Detailed Description

In order that the invention may be readily understood, a more complete description of the invention will be rendered by reference to the appended drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 and 2, an automatic reel changer according to an embodiment of the present invention includes a mounting frame 10, an unreeling mechanism 20, a stock preparing mechanism 30 and a tape splicing mechanism 40. The unreeling mechanism 20 includes an unreeling shaft 21 rotatably connected to the mounting frame 10 about its own axis. The stock preparation mechanism 30 includes a stock preparation shaft 32 and a stock pusher 33 (see fig. 6). The stock shaft 32 has a butt end 320. The stock shaft 32 is rotatably connected to the mounting frame 10 about a rotation axis. The pushing member 33 is configured to provide axial pushing force to the stock roll on the stock shaft 32. The stock shaft 32 includes a pushing position during rotation about the rotation axis. When the stock shaft 32 is in the pushing position, the abutting end 320 of the stock shaft 32 abuts against the unwinding shaft 21, and the pushing member 33 is controlled to push the stock roll on the stock shaft 32 to be transferred to the unwinding shaft 21. It will be appreciated that the above-mentioned axis of rotation is not parallel to the axis of the stock shaft 32, since the rotation of the stock shaft 32 to the pushing position is to be achieved. Preferably, the axis of rotation is perpendicular to the axis of the preparation shaft 32.

The tape splicing mechanism 40 is provided to the mounting frame 10 for cutting off the work tape discharged from the reel 21 and connecting the cut work tape to the stock roll on the reel 21.

In the automatic reel changer, when the work roll on the reel 21 is used up and the reel needs to be replaced, the work tape released from the reel 21 is first cut by the tape receiving mechanism 40, and the cartridge (the roll includes the cartridge and the tape wound around the cartridge) on the reel 21 is discharged. The stock shaft 32 is then rotated about the rotation axis such that the docking end 320 of the stock shaft 32 is docked with the unwind shaft 21, and then the pusher 33 pushes the stock roll on the stock shaft 32 to transfer to the unwind shaft 21. Finally, the cut-off working tape is connected to the stock roll on the unreeling shaft 21 by the tape connecting mechanism 40, thereby realizing automatic roll change. Therefore, compared with the automatic reel changing device which needs to be provided with two sets of unreeling mechanisms which are mutually standby in the prior art, the automatic reel changing device disclosed by the invention has the advantages that the material preparing shaft 32 and the pushing piece 33 are utilized to push the material preparing reel on the material preparing shaft 32 to the unreeling shaft 21, and two sets of unreeling mechanisms 20 do not need to be provided, so that the structure of the automatic reel changing device is greatly simplified, and the occupied space is reduced.

It should be noted that, the pushing member 33 provides axial pushing force to the stock roll on the stock shaft 32, which is understood as follows: the pushing force provided by the pushing member 33 may be the pushing force itself parallel to the axial direction of the stock shaft 32, or may be a component force having an axial direction parallel to the stock shaft 32, so long as pushing of the stock roll on the stock shaft 32 onto the unreeling shaft 21 can be achieved, which is not limited herein.

In the embodiment of the invention, the unreeling shaft 21 is movable relative to the mounting frame 10 in its own axial direction. In this way, deviation correction (i.e. the position of the trimming strip in its width direction) can be achieved by the axial displacement of the unwinding shaft 21 itself.

Referring to fig. 3 and 4, in the embodiment of the invention, the unreeling mechanism 20 further includes a first guide post 22, a rotating shaft 23, a first driving component 24 and a second driving component 25. The first guide post 22 is movably connected to the mounting frame 10 along its own axis. The rotary shaft 23 is axially fixed and circumferentially rotatably coupled within the first guide post 22. That is, the first guide post 22 is a hollow post, the rotating shaft 23 is sleeved in the first guide post 22, and the rotating shaft 23 can rotate around its own axis relative to the first guide post 22 and is fixed relative to the first guide post 22 in the axial direction of the rotating shaft 23. The unreeling shaft 21 is fixedly connected to one end of the rotating shaft 23 so that the unreeling shaft 21 rotates synchronously with the rotating shaft 23, thereby realizing unreeling. The first driving assembly 24 is disposed on the mounting frame 10 and is in transmission connection with the first guide post 22, so that the first driving assembly 24 drives the first guide post 22 to move along the self axis relative to the mounting frame 10, thereby driving the unwinding shaft 21 to move along the self axis. The second driving assembly 25 is disposed on the first guide post 22 and is in transmission connection with the rotating shaft 23, so that the second driving assembly 25 drives the rotating shaft 23 to rotate around its own axis, thereby driving the unwinding shaft 21 to rotate. In this way, the first driving assembly 24 and the second driving assembly 25 respectively drive the unwinding shaft 21 to move along the axis of the unwinding shaft and rotate around the axis of the unwinding shaft, so that the structure is simple, and the operation is stable. And, locate the rotation axis 23 cover in first guide pillar 22 in favor of reducing the structure volume, reduce occupation space. Preferably, the first guide post 22, the rotating shaft 23 and the unreeling shaft 21 are coaxially arranged.

In particular, in the embodiment, the rotation shaft 23 may be mounted in the first guide post 22 through a bearing, so that the rotation shaft 23 is rotatable relative to the first guide post 22 and fixed relative to the first guide post 22 in the axial direction.

In some embodiments, unwind mechanism 20 further includes a roller assembly 26. The roller assembly 26 includes a second guide post 261 and a roller 262. The second guide post 261 is movably connected to the mounting frame 10 in a direction parallel to the first guide post 22, and the second guide post 261 and the first guide post 22 are controllably connected to or separated from each other. The passing roller 262 is mounted to the second guide post 261 for guiding the working web discharged from the unreeling shaft 21. So, when need rectify to the work material area, control second guide pillar 261 is connected with first guide pillar 22 for second guide pillar 261 and first guide pillar 22 synchronous motion, thereby realize unreeling shaft 21 and cross roller 262 and remove along being on a parallel with the axis direction of unreeling shaft 21 in step, and then realize adjusting (rectifying) the position in the material area width direction, so avoided the work material area and cross roller 262 and produced the relative movement in the axial direction of unreeling shaft 21 in the process of rectifying, thereby lead to the fact the phenomenon of wearing and tearing to the work material area, be favorable to improving product quality. When deviation correction is not needed, the second guide post 261 is controlled to be separated from the first guide post 22, so that the first guide post 22 is prevented from moving along the axis (such as reel change and unloading) to drive the second guide post 261 and the roller 262 to move.

In the embodiment, the driving portion 241 is fixedly connected to the first guide post 22. The second guide post 261 is fixedly connected with a mounting member 263. The roller assembly 26 also includes a fixed hug 264 and a movable hug 265. The fixed clasping member 264 is mounted to the mounting member 263 and abuts against one side of the driving portion 241. The movable hug 265 is movably connected to the mount 263. The movable clasping member 265 can prop against the opposite side of the driving portion 241 in the moving process, so that the driving portion 241 is clasped by the fixed clasping member 264 and the movable clasping member 265, that is, the connection between the second guide post 261 and the first guide post 22 is realized. When the second guide post 261 and the first guide post 22 need to be separated, the movable hug 265 is moved, so that the movable hug 265 and the fixed hug 264 are released and separated from the driving part 241. Alternatively, the second guide post 261 may include two or more parallel to each other, so that on one hand, the movement stability of the over-roller 262 is improved and the shake of the over-roller 262 is reduced; on the other hand, can function to prevent the second guide post 261 from rotating.

Further, the roller assembly 26 further includes a roller mounting plate 266, the roller mounting plate 266 being fixedly connected to the second guide post 261, the roller 262 being mounted to the roller mounting plate 266.

In particular, in one embodiment, the roller assembly 26 further includes a first rail 2630 and a first driver 267. The first sliding rail 2630 is fixedly connected to the mounting member 263. The movable clasping member 265 is disposed on the first sliding rail 2630 and is slidable along the first sliding rail 2630. The first driving member 267 is fixedly connected to the mounting member 263 and is in driving connection with the movable clasping member 265 to drive the movable clasping member 265 to move along the first sliding rail 2630. In this way, the first sliding rail 2630 and the first driving member 267 are utilized to realize the movement of the movable clasping member 265, so that the clasping and releasing actions are stable and reliable. Alternatively, the first driver 267 may be a cylinder. It is understood that the first driving member 267 may be any other driving member capable of performing linear reciprocating motion, which is not limited herein.

Further, the fixed hug 264 and the movable hug 265 are respectively located at two sides of the driving part 241 in a direction perpendicular to the first guide post 22, so as to prevent interference to the movement of the first guide post 22 along the axis thereof when the fixed hug 264 and the movable hug 265 release the driving part 241.

Further, a side of the driving part 241 facing the movable hug 265 has a fitting groove that can be fitted with the movable hug 265. In this way, the stability of the movable clasping member 265 and the fixed clasping member 264 when clasping the driving portion 241 is further improved. Alternatively, both the fixed hug 264 and the movable hug 265 may be rollers. When the fixed hugging member 264 and the movable hugging member 265 are released, the fixed hugging member 264 can roll on the surface of the driving part 241, reducing friction.

In some embodiments, the over-roller assembly 26 also includes a lock 268 and a lock lever 269. The locking member 268 is fixedly coupled to the mounting member 263 and the locking lever 269 is fixedly coupled to the mounting frame 10. The locking lever 269 is parallel to the second guide post 261, and the locking piece 268 is controllably connected to or disconnected from the locking lever 269. Thus, when no deviation correction is required, the second guide post 261 is separated from the first guide post 22, and at this time, the locking piece 268 may be connected with the locking lever 269 in order to prevent the over roller 262 from moving. When correction is needed, the locking piece 268 is separated from the locking rod 269, and the second guide post 261 is connected with the first guide post 22, so that the second guide post 261 and the first guide post 22 can synchronously move along the axial direction of the first guide post 22, namely, the over roller 262 and the unreeling shaft 21 synchronously move along the axial direction of the unreeling shaft 21, and correction is further achieved. Alternatively, the lock 268 may be a jaw cylinder.

In some embodiments, the first drive assembly 24 includes a first lead screw 242, a first lead screw nut 243, and a slider 244. One end of the first screw 242 is rotatably connected to the mounting frame 10 around its own axis and is parallel to the first guide post 22. The first screw nut 243 is screw-coupled to the first screw 242. The slider 244 is fixedly connected to the first guide post 22 and the first lead screw nut 243. In this way, the first screw nut 243 is driven to move along the first screw 242 by the rotation of the first screw 242, so as to drive the slider 244 and the first guide post 22 to move along the axial direction of the first guide post 22, and further drive the unreeling shaft 21 to move along the axis thereof. Further, the driving part 241 is fixedly connected to the slider 244.

In particular, in the illustrated embodiment, the first drive assembly 24 further includes a third guide post 245, a first mount 246, and a screw drive 247. One end of the third guide post 245 is fixedly connected to the mounting frame 10 and is parallel to the first guide post 22. The first mounting seat 246 is fixedly connected to the other end of the third guide post 245. The screw driving member 247 is mounted on the first mounting seat 246 and is in transmission connection with one end of the first screw 242 far away from the mounting frame 10, so that the screw driving member 247 drives the first screw 242 to rotate around the axis thereof. Further, the sliding member 244 is disposed on the third guide post 245 and is slidable along the third guide post 245, so as to guide the sliding member 244, and make the movement of the sliding member 244 more stable. Specifically, the screw driving member 247 may be a motor.

Alternatively, the output shaft of the screw drive 247 may be drivingly connected to the first screw 242 by a coupling.

In order to further stabilize the movement of the respective sliding members, the sliding member 244 may optionally be slidably mounted to the third guide post 245 by a guide sleeve. The first guide post 22 may also be slidably mounted to the mounting frame 10 via a guide sleeve. The second guide post 261 may also be slidably mounted to the mounting frame 10 via a guide sleeve.

In some embodiments, the second driving assembly 25 includes a second mounting seat 251, a rotation driving member 252 and a transmission structure. The second mounting seat 251 is fixedly connected to the first guide post 22. The rotation driving part 252 is mounted to the second mounting seat 251. The transmission structure is connected between the rotation driving member 252 and the rotation shaft 23 in a transmission manner, so that the rotation shaft 23 is driven by the rotation driving member 252 to rotate around the self axis, and the unwinding shaft 21 is driven to rotate around the self axis. In particular embodiments, the second mount 251 is fixedly coupled to the slider 244.

In particular embodiments, the transmission structure includes a driving gear 253 and a driven gear 254 that intermesh. The driving gear 253 is mounted to the output shaft of the rotary driver 252 such that the driving gear 253 and the output shaft of the rotary driver 252 are rotated in synchronization. The driven gear 254 is mounted to the rotation shaft 23 such that the driven gear 254 rotates in synchronization with the rotation shaft 23. In this way, the rotational motion output from the rotational driver 252 is transmitted to the rotation shaft 23 through the driving gear 253 and the driven gear 254 engaged with each other, thereby driving the rotation shaft 23 to rotate. The transmission structure is not limited to a gear transmission structure, and may be a structure such as a belt transmission structure, and is not limited thereto. Alternatively, the rotary drive may be a motor.

The unreeling shaft 21 and the passing roller 262 are located on the same side of the mounting frame 10, so that the material belt discharged from the unreeling shaft 21 is guided by the roller 262. The first guide post 22 and the second guide post 261 penetrate through two opposite sides of the mounting frame 10, and the third guide post 245 is located on one side of the mounting frame 10 away from the unreeling shaft 21.

In an embodiment of the present invention, the stock preparation mechanism 30 further includes a pushing member 34 (see fig. 1). The stock shaft 32 also has a push end 322 opposite the butt end 320. The pushing member 34 is fixedly connected to the pushing end 322. The stock shaft 32 also includes a stock position during rotation about the axis of rotation. When the stock shaft 32 is in the stock position, the pushing member 34 faces the unwinding shaft 21 for pushing the stock roll on the unwinding shaft 21. In this way, after the pushing member 33 pushes the stock roll on the stock shaft 32 onto the unwinding shaft 21, the unwinding shaft 21 moves along the axis thereof in a direction away from the stock shaft 32, and the stock shaft 32 rotates about the rotation axis to the stock position so that the pushing member 34 faces the unwinding shaft 21. The unwind shaft 21 is then moved along its axis in a direction towards the stock shaft 32, the pushing member 34 being in close abutment against the stock roll on the unwind shaft 21, so that the stock roll and the unwind shaft 21 are moved relatively along the axis of the unwind shaft 21 for adjusting (i.e. positioning) the position of the stock roll on the unwind shaft 21. Optionally, the pushing element 34 includes a body fixedly connected to the pushing end 322 and a plurality of pushing claws disposed around the body. Each pushing claw extends to one side of the body away from the pushing end 322 and is used for contacting with the stock roll on the unreeling shaft 21 so as to push the stock roll. In this way, the unwinding shaft 21 is prevented from coming into contact with the pushing member 34.

In order to prevent the standby shaft 32 from interfering with the movement of the pushing member 34 during the process of rotating the standby shaft 32 to the standby position about the rotation axis, the standby shaft 21 and the standby roll on the standby shaft 21 need to be moved in a direction away from the standby shaft 32 along the axis thereof before rotating the standby shaft 32 to the standby position, thereby effectively avoiding the situation. When the stock shaft 32 rotates to the stock position, the unwinding shaft 21 moves along its axis in a direction approaching the stock shaft 32, and the stock roll on the unwinding shaft 21 is pushed by the pushing member, so that the stock roll is positioned on the unwinding shaft 21.

In particular, in the embodiment, the positioning block 27 is provided on the unreeling shaft 21. In this way, the backup roll on the unwinding reel 21 is pushed against the pushing member 34 until the backup roll is positioned against the positioning block 27, i.e. the backup roll is pushed against in place.

It should be noted that the positioning of the stock roll on the unwinding shaft 21 is not limited to the manner in which the pushing member is mounted on the stock shaft 32, and in other embodiments, a separate pushing mechanism may be designed. Referring to fig. 8, the pushing mechanism includes a pushing shaft 52 and a pushing member 53, where the pushing shaft 52 is rotatably connected to the mounting frame 10 around its own axis. The pushing member 53 is mounted to the pushing shaft 52. The pushing member 53 includes a pushing position during rotation of the pushing shaft 52 about its own axis. When the pushing member 53 is located at the pushing position, the pushing member 53 is located between the unwinding shaft 21 and the stock shaft 32, and is used for pushing the stock roll on the unwinding shaft 21.

In this way, when the pushing member 33 pushes the stock roll on the stock shaft 32 onto the unwinding shaft 21, the unwinding shaft 21 moves along its own axis in a direction away from the stock shaft 32, and the pushing shaft 52 of the pushing mechanism rotates to drive the pushing member 53 to be in the pushing position, where the pushing member 53 is located between the unwinding shaft 21 and the stock shaft 32. Then, the unwinding shaft 21 moves along its own axis toward one end near the stock shaft 32, so that the pushing member 53 tightly pushes the stock roll on the unwinding shaft 21, thereby pushing the stock roll into place. Finally, the rotation of the pushing shaft 52 drives the pushing member 53 to rotate to the initial position, and the unwinding shaft 21 moves to the working position along its own axis.

In the embodiment, the pushing mechanism includes a third mounting seat 54 and a pushing driving member 55. The third mount 54 is fixedly mounted to the mount 10. The pushing shaft 52 is rotatably connected to the third mount 54 about its own axis. The pushing driving member 55 is disposed on the third mounting seat 54, and is in transmission connection with the pushing shaft 52, so as to drive the pushing shaft 52 to rotate around its own axis.

Further, the pushing driver 55 may be a cylinder. The pushing mechanism further comprises a driving block 57 and a hinge seat 56. The driving block 57 is fixedly connected to the pushing shaft 52, and the hinge seat 56 is fixedly connected to the third mounting seat 54. The fixed end of the pushing driving member 55 is hinged to the hinge seat 56, and the hinge axis is parallel to the axis of the pushing shaft 52. The drive end of the push drive member 55 is hingedly connected to the drive block 57 with the hinge axis parallel and non-collinear with the axis of the push shaft 52. In this way, the driving end of the pushing member 55 is extended and contracted, so that the pushing shaft 52 is driven to rotate around its own axis, and the pushing member 53 is driven to swing.

Further, the pushing mechanism further includes a rotary support base 57, and the rotary support base 57 is fixedly connected to the third mounting base 54. The pushing shaft 52 is disposed through the rotation support base 57 and can rotate relative to the rotation support base 57. Specifically, the thrust shaft 52 is mounted to the rotation support base 57 through a bearing.

In the embodiment, the pushing mechanism further includes an adjusting block 58, an adjusting rod 59, and a first elastic member 591. The adjusting block 58 is fixedly connected to the pushing shaft 52, and the pushing member 53 is movably mounted at one end of the pushing shaft 52 along the axis of the pushing shaft 52. One end of the adjustment lever 59 penetrates the adjustment block 58 and is connected to the pushing member 53. The first elastic member 591 is disposed on a side of the adjusting block 58 away from the pushing member 53, and one end of the first elastic member 591 abuts against the adjusting rod 59, and the opposite end abuts against the adjusting block 58, so as to provide a pre-tightening force for the pushing member 53 to move toward the adjusting block 58 along the axis of the pushing shaft 52. Alternatively, the first elastic member 591 may be a compression spring. The compression spring is sleeved on the adjusting rod 59 and is positioned on the side of the adjusting block 58 away from the pushing piece 53. Alternatively, the adjusting rod 59 is a screw, which is screwed to the pushing member 53.

In this way, when the pushing member 53 is in the pushing position (i.e. between the unwinding shaft 21 and the stock shaft 32), the unwinding shaft 21 moves along its own axis towards the stock shaft 32, and the stock roll on the unwinding shaft 21 contacts the pushing member 53, so as to compress the first elastic member 591 for buffering, and make the pushing member 53 abut against the stock shaft 32 for supporting. When the unwinding shaft 21 continues to move along its own axis toward the stock shaft 32, the pushing member 53 pushes the stock roll on the unwinding shaft 21 to move relative to the unwinding shaft 21, so that it reaches the working position.

Further, the pushing mechanism also includes a guide rod 592. The guide rod 592 is disposed through the adjusting block 58 and is slidable relative to the adjusting block 58, and one end of the guide rod 592 is fixedly connected to the pushing member 53. In this manner, the guide rod 592 can guide the thrust piece 53 to slide along the axis of the thrust shaft 52. It will be appreciated that the guide rod 592 is parallel to the thrust shaft 52.

Referring to fig. 5, 6 and 7, in the embodiment of the invention, the stock shaft 32 is a hollow shaft. At least one sliding groove 321 is formed in the circumferential side wall of the material preparation shaft 32. The slide groove 321 extends longitudinally along the axial direction of the stock shaft 32. The pushing member 33 is slidably disposed in the stock shaft 32 along the axial direction of the stock shaft 32, and extends out of the stock shaft 32 from the corresponding sliding slot 321. In this way, the preparation roll is sleeved on the preparation shaft 32, and when the pushing member 33 slides along the sliding groove 321, the portion of the pushing member 33 extending out of the sliding groove 321 pushes the preparation roll to move along the preparation shaft 32 until the preparation shaft 32 is pushed onto the unwinding shaft 21.

In some embodiments, the stock preparation mechanism 30 further includes a pushing driving assembly including a pushing screw 361, a pushing screw nut 35, and a pushing driving member 36. The pushing screw 361 is disposed in the stock shaft 32 and rotatable relative to the stock shaft 32. The pushing screw nut 35 is screwed to the pushing screw 361. The pushing piece 33 and the pushing screw nut 35 are relatively and fixedly arranged. The pushing driving member 36 is installed at one end of the stock shaft 32, and is in transmission connection with the pushing screw 361, so as to drive the pushing screw 361 to rotate. Thus, when the stock roll on the stock shaft 32 needs to be pushed onto the unwinding shaft 21, the pushing driving member 36 drives the pushing screw 361 to rotate, so as to drive the pushing screw nut 35 to move along the pushing screw 361, and further drive the pushing member 33 to move along the pushing screw 361 (i.e. move along the axial direction of the stock shaft 32). It can be appreciated that the pushing screw 361 and the stock shaft 32 are axially parallel to each other. Preferably, the pushing ram 361 is coaxially disposed within the equipment shaft 32.

In particular embodiments, the pushing drive assembly further includes a drive bevel gear 362 and a driven bevel gear 364 that intermesh. The drive bevel gear 362 is mounted to the output shaft of the pushing drive 36, and the driven bevel gear 364 is mounted to one end of the pushing screw 361. In this way, the transmission between the pusher drive 36 and the pusher screw 361 is achieved by the intermeshing drive bevel gear 362 and driven bevel gear 364. Alternatively, the pushing drive 36 may be a motor.

In particular embodiments, the pushing driving assembly further includes a driving wheel 37 fixedly sleeved outside the pushing screw nut 35. The pusher 33 is fixedly connected to the drive wheel 37.

To guide the drive wheel 37, in one embodiment, the push drive assembly further includes a push guide bar fixedly mounted within the stock shaft 32, the push guide bar being parallel to the axis of the stock shaft 32 and extending through the drive wheel 37, the drive wheel 37 being slidable along the push guide bar. In this way, the pushing guide rod is used for guiding the movement of the driving wheel 37, so that the movement of the pushing member 33 is more stable, and the pushing action is stable and reliable. In another embodiment, the pushing guide bar may not be provided, and the movement of the driving wheel 37 may be guided by the inner wall of the stock shaft 32. That is, the driving wheel 37 is slidably fitted with the circumferential inner wall of the stock shaft 32 so that the driving wheel 37 can slide along the circumferential inner wall of the stock shaft 32, thereby achieving guiding of the movement of the driving piece 37.

In the embodiment, the pushing driving assembly further comprises a guiding roller installed on the driving wheel 37, and the guiding roller is in rolling fit with the sliding groove 321 to roll along the sliding groove 321, so as to guide the driving wheel 37 and the pushing member 33 to move along the axial direction of the material preparation shaft 32, and make the pushing of the pushing member 33 more stable. Since the guide rollers are arranged for guiding, the pushing piece 33 can only pass through the chute 321 to the outside of the material preparation shaft 32 and is not contacted with the inner wall of the chute 321 for guiding, thereby avoiding abrasion caused by the contact of the pushing piece 33 and the inner wall of the chute 321.

More specifically, two sliding grooves 321 are formed in the material preparing shaft 32, and each sliding groove 321 is correspondingly provided with a material pushing piece 33. In this way, the two pushing members 33 are respectively arranged to move along the two sliding grooves 321, so that the pushing of the pushing members 33 is more stable. Two slide grooves 321 are positioned at the bottom of the stock shaft 32.

In particular embodiments, the stock preparation mechanism 30 further includes a first sensor 391. The circumference of the stock shaft 32 is provided with a detection port. The first sensor 391 is mounted to the detection port for detecting the position of the drive wheel 37. In this way, the first sensor 391 can detect the position of the driving wheel 37 to limit the movement range of the driving wheel 37, so as to prevent the driving wheel 37 from colliding with the components at the two ends of the material preparation shaft 32. It will be appreciated that the drive wheel 37 is provided with a sensing mass corresponding to the first sensor 391.

In particular embodiments, the preparation shaft 32 has at least one equipment location along its axis for the preparation roll sleeve equipment. Each standby level is provided with a second sensor. The second sensor is used for detecting whether a corresponding material preparation position is sleeved with a material preparation roll. In this manner, the second sensor 392 can detect whether a stock roll is present at each stock level on the stock shaft 32.

Preferably, the first sensors 391 include two detecting ports, the two detecting ports are arranged at intervals along the axial direction of the stock shaft 32, and the two first sensors 391 are respectively installed in the two detecting ports. In order to avoid the second sensor 392 affecting the loading of the stock shaft 32 with the stock roll, a detection groove may be formed in the circumference of the stock shaft 32, and the detection groove is communicated with the two detection ports. A plurality of second sensors 392 are disposed within the detection recess. Further, the stock preparing mechanism 30 further includes a cover plate 393, where the cover plate 393 covers the detecting groove, for preventing the second sensor 392 from falling off. The cover plate 393 is provided with a detection notch at a position corresponding to the second sensor 392. The second sensor 392 detects the roll of stock material through the corresponding detection gap.

In particular embodiments, the feed preparation mechanism 30 further includes a plurality of guide wheels 323. The circumferential surface of the stock shaft 32 is provided with a guide groove extending lengthwise along the axial direction of the stock shaft 32, and a plurality of guide wheels 323 are provided in the guide groove and are disposed along the lengthwise extending direction of the guide groove. Each guide wheel 323 partially protrudes from the peripheral side surface of the stock shaft 32. In this way, the guide wheel 323 guides the movement of the stock roll along the axial direction of the stock shaft 32, so that the movement of the stock roll is more stable. Optionally, a guide slot is provided at the top of the stock shaft 32.

In particular embodiments, wear strips 326 are provided on the circumferential side walls of the stock shaft 32. The wear strips 326 extend longitudinally in the axial direction of the stock shaft 32. The wear strips 326 are used to prevent the stock roll from causing wear to the stock shaft 32 as it is frequently moved over the stock shaft 32. Further, a mounting groove for mounting the wear strip 326 is formed in the circumferential side wall of the stock shaft 32. The wear strip 326 partially protrudes from the peripheral surface of the stock shaft 32.

In an embodiment, the circumferential outer surface of the abutting end 320 of the stock shaft 32 is provided with a tensioning groove, and the stock mechanism further comprises a tensioning assembly 327 disposed in the tensioning groove. The tensioning assembly 327 is controllably movable in a radial direction of the preparation shaft 32 to extend or retract the tensioning slots. When the tensioning assembly 327 moves along the radial direction of the material preparation shaft 32 and extends out of the tensioning groove, the tensioning assembly 327 is in tensioning fit with the material preparation roll at the butt joint end 320, and at this time, the material preparation roll is fixed relative to the material preparation shaft 32, i.e. the material preparation roll cannot move along the axial direction of the material preparation shaft 32, so that the material preparation roll is prevented from being thrown out under the action of centrifugal force in the rotation process of the material preparation shaft 32. When the tensioning assembly 327 moves along the radial direction of the stock shaft 32 to retract the tensioning groove, the tensioning assembly 327 releases the tensioning of the stock roll sleeved at the butt end 320, and the stock roll can move along the axial direction of the stock shaft 32 to facilitate roll changing.

Further, the tensioning assembly 327 includes a tensioning block and an expansion member. The tensioning block is arranged in the tensioning groove of the material preparation shaft 32, and the tensioning block can extend or retract the tensioning groove along the radial movement of the material preparation shaft 32. The expansion piece is arranged between the bottom wall of the tensioning groove and the tensioning block. The expansion member is controllably expanded or contracted to drive the radial movement of the tensioning block along the feed shaft 32. Alternatively, the inflatable member may be a balloon. When the preparation roll needs to be fixed, the air bag is inflated, so that the tensioning block can move outwards along the radial direction of the preparation shaft 32, and the tensioning block stretches out of the tensioning groove, so that the preparation roll is fixed relative to the preparation shaft 32. When the reserve roll does not need to be fixed, the air bag is deflated, so that the tensioning block can move inwards along the radial direction of the reserve shaft 32, and the tensioning block is retracted into the tensioning groove, so that the reserve roll is released.

In particular embodiments, the stock solution mechanism 30 further includes a first end cap 324 and a second end cap 325 fixedly mounted to the mating end 320 and the pushing end 322, respectively, of the stock shaft 32. Opposite ends of the push screw 361 are rotatably coupled to the first and second end caps 324 and 325, respectively, by bearings.

In particular, in the embodiment, the stock preparation mechanism 30 further includes a mounting bracket 311, a rotating bracket 312, a stock preparation driving member 313, and a stock preparation transmission assembly. The mounting bracket 311 is fixedly mounted to the mounting bracket 10, and the swivel bracket 312 is rotatably connected to the mounting bracket 311 about a swivel axis. The pushing end 322 of the stock shaft 32 is fixedly connected to the rotating bracket 312. The stock driving member 313 is disposed on the mounting frame 10, and the stock driving assembly is in transmission connection between the stock driving member 313 and the rotating bracket 312, so that the stock driving member 313 drives the rotating bracket 312 to rotate around the rotation axis through the stock driving assembly, thereby realizing that the stock shaft 32 is rotatable around the rotation axis. Alternatively, the mounting bracket 311 and the stock drive 313 are located on opposite sides of the mounting frame 10, respectively.

Further, the stock driving assembly includes a stock driving wheel 314, a stock driven wheel 315, a stock driving belt 316, and a stock rotating shaft 317. The rotary bracket 312 is rotatably connected to the mounting bracket 311 about a rotation axis by a stock rotation shaft 317. The stock driving wheel 314 is mounted on the output shaft of the stock driving member 313 to rotate synchronously with the output shaft of the stock driving member 313. The stock follower 315 is mounted to the stock rotating shaft 317 to rotate in synchronization with the stock rotating shaft 317. The stock driving belt 316 is sleeved between the stock driving wheel 314 and the stock driven wheel 315, so that the stock driving wheel 314 and the stock driven wheel 315 rotate synchronously. It should be noted that the stock driving assembly is not limited to the belt driving method, and in other embodiments, for example, a gear driving method may be used, which is not limited herein. Alternatively, the stock drive 313 may be a motor.

Referring to fig. 1 and 9, in the embodiment of the invention, the automatic reel changer further includes a waste collection mechanism 60 for unloading the cartridges on the unreeling shaft 21. Before pushing the preparation roll on the preparation shaft 32 onto the unwinding shaft 21, the cartridges on the unwinding shaft 21 need to be unloaded, and the waste collection mechanism 60 is used to unload the cartridges on the unwinding shaft 21.

The waste collection mechanism 60 includes a grasping assembly 62 rotatably coupled to the mounting frame 10 about a first axis. The gripper assembly 62 includes a gripping position and a discharging position during rotation about the first axis. The gripper assembly 62 is used to grip the cartridge on the unwind shaft 21 when the gripper assembly 62 is in the gripping position; the gripper assembly 62 releases the cartridge when the gripper assembly 62 is in the discharge position. When the work roll on the unreeling shaft 21 runs out in this way, the work tape released from the unreeling shaft 21 is cut off by the tape receiving mechanism 40. The gripper assembly 62 is then rotated about the first axis to a gripping position and grips the cartridge on the unwind spool 21. Then, the unreeling shaft 21 is moved along the axis, so that the cartridge is separated from the unreeling shaft 21. Subsequently, the gripper assembly 62 is rotated about the first axis to a discharge position, i.e. the cartridge separated from the discharge shaft 21 is transferred to the discharge position and released. That is, automatic unloading of the waste is realized, manual unloading is avoided, labor cost is reduced, and production efficiency is improved.

In some embodiments, the grasping assembly 62 includes a rotational shaft 621, a second drive 622, a first swing arm 623, and a grip 624. The rotary shaft 621 is rotatably connected to the mount 10 about its own axis. It is understood that the axis of the rotating shaft 621 is the first axis. The second driving member 622 is disposed on the mounting frame 10 and is drivingly connected to the rotating shaft 621 to drive the rotating shaft 621 to rotate about its own axis. One end of the first swing arm 623 is fixedly connected to the rotating shaft 621, and the grip 624 is disposed at the other end of the first swing arm 623. Thus, when the second driving member 622 drives the rotating shaft 621 to rotate, and drives the gripper 624 to the gripping position, the gripper 624 grips the cartridge on the unreeling shaft 21, i.e. the cartridge is fixed relative to the gripper 624. The unwind shaft 21 is then moved along its axis so that the cartridges are separated from the unwind shaft 21. Then, the second driving member 622 drives the rotating shaft 621 to rotate, so as to drive the gripper 624 to the discharging position, and at this time, the gripper 624 releases the cartridge, thereby unloading the cartridge on the discharging shaft 21. Alternatively, the grip 624 may be a jaw cylinder.

In particular embodiments, the grasping assembly 62 further includes a first slider 625 and a third drive 626. The first slider 625 is slidably connected to the first swing arm 623 along the longitudinal direction of the first swing arm 623. The grip 624 is disposed on the first slider 625. The third driving member 626 is disposed on the first swing arm 623 and is in driving connection with the grip 624 to drive the grip 624 to move along the longitudinal direction of the first swing arm 623. When the first swing arm 623 rotates around the first axis to the discharging position, the third driving member 626 drives the grip 624 gripping the barrel to move along the longitudinal direction of the first swing arm 623, so that the grip 624 approaches the storage area, and the barrel is easily discharged, thereby avoiding impact. Alternatively, the third driving member 626 may be a cylinder.

Further, one side of the first swing arm 623 has a guide rail 6232, and the first slider 625 is disposed on the guide rail 6232 and can slide along the guide rail 6232. The opposite side of the first swing arm 623 is provided with a third driving member 626. That is, the first slider 625 and the third driving piece 626 are located at opposite sides of the first swing arm 623, respectively. In this way, the movement of the grip 624 is made smoother and more reliable.

In particular embodiments, the output shaft of the second drive member 622 may be drivingly connected to the rotatable shaft 621 by a coupling. Alternatively, the second drive 622 may be a motor. More specifically, the second driving member 622 may be fixedly mounted to the mounting frame 10 through a fixing base, so as to ensure connection stability of the second driving member 622 and reduce vibration of the second driving member 622.

In some embodiments, the waste collection mechanism 60 also includes a storage assembly 64. The storage assembly 64 is located below the grasping assembly 62. The storage assembly 64 includes a sled 641. The slider 641 has a plurality of storage areas for storing cartridges arranged at intervals along the first direction (the "plurality" of the plurality of storage areas is to be understood as two or more). The slide 642 is slidably connected to the mounting frame 10 along a first direction to drive the plurality of storage areas to sequentially move below the discharging position so as to receive the cartridges released by the grippers 624. As such, the gripper assembly 62 releases the cartridge at the discharge location such that the cartridge falls into the storage area. And when one storage area is full of cartridges, slide 641 moves in a first direction so that the other storage area moves below the discharge position.

Preferably, the first direction is parallel to the first axis. In this manner, the volume occupied by the garbage collection mechanism 60 in a direction perpendicular to the first axis is advantageously reduced.

In particular, in one embodiment, the storage assembly 64 further includes a second screw and a fourth driver 643. The second screw is rotatably connected to the mounting frame 10 about its own axis. The slide 641 is screw-coupled to the second screw. The fourth driving part 643 is disposed on the mounting frame 10 and is connected to the second screw rod in a transmission manner, so as to drive the second screw rod to rotate around its own axis. In this way, the fourth driving member 643 drives the second screw to rotate, so that the slide 641 moves along the axial direction of the second screw, and further sequentially moves the plurality of storage areas to a position below the discharging position. It will be appreciated that the axis of the second screw is parallel to the first direction. More specifically, the storage assembly 64 also includes a second lead screw nut. The second screw nut is in threaded connection with the second screw. The slide 641 is fixedly coupled to the second lead screw nut. That is, the slider 641 is indirectly screw-coupled to the second screw through a second screw nut.

Further, the storage assembly 64 also includes a guide rod 644. One end of the guide rod 644 is fixedly coupled to the mounting frame 10. And is parallel to the second screw rod. The slide 641 is slidably coupled to a guide 644. In this way, the sliding of the slide 641 is guided by the guide rod 644, so that the movement of the slide 641 is more stable and reliable.

Alternatively, the fourth driving member 643 may be a motor. The output shaft of the fourth driving member 643 may be drivingly connected to the second lead screw through a coupling.

In particular embodiments, the storage assembly 64 further includes two support rods 645. Two support rods 645 are fixedly coupled to the carriage 641. The two support bars 645 are spaced apart and each parallel to the first direction. A storage space for carrying the cartridge is formed between the two support bars 645. The storage space includes a plurality of storage areas arranged along a first direction. In this way, the cartridge may be placed in the storage area of the storage space from above the two support rods 645, so that the two support rods 645 carry the cartridge to achieve storage. When the cartridge needs to be removed, it is only necessary to lift the cartridge upward to separate it from the support bar 645. In order to load the cartridge, the distance between the two support rods 645 is smaller than the diameter of the cartridge.

Further, the storage assembly 64 also includes a plurality of dividers 646. The plurality of partition members 646 are fixedly connected to the two support rods 645 and are arranged at intervals along the longitudinal direction of the support rods 645 to separate the plurality of storage areas (i.e., one partition member 646 is disposed between every two adjacent storage areas). That is, the plurality of partitions 646 divide the storage space into a plurality of storage areas each for storing one cartridge in the longitudinal direction of the support bar 645. In this manner, the provision of the partition 646 effectively avoids interaction between two cartridges located in adjacent two storage areas.

Referring to fig. 10, 11 and 12, in the embodiment of the invention, the tape splicing mechanism 40 includes a second swing arm 41, a clamping assembly 42 and a cutter 43. One end of the second swing arm 41 is rotatably connected to the mounting frame 10 around the second axis, the clamping assembly 42 is rotatably connected to the other end of the second swing arm 41 around the third axis, the clamping assembly 42 is used for clamping the working material belt, the cutter 43 is arranged on the second swing arm 41 and can approach or depart from the clamping assembly 42, and the cutter 43 is used for cutting off the material belt. Thus, when a reel change is required, the clamping assembly 42 of the take-up mechanism 40 clamps the working web paid out on the pay-off spool 21. The knife is then moved toward the clamping assembly 42 to sever the clamped working web. The scrap collecting mechanism 60 then removes the cartridge from the unwind shaft 21, and the pusher 33 pushes the stock roll from the stock shaft 32 onto the unwind shaft 21 and positions the stock roll from the unwind shaft 21. The clamp assembly 42 rotates about the third axis such that the severed working web portion wraps around the clamp assembly 42. Finally, the second swing arm 41 rotates to bring the working tape clamped by the clamping assembly 42 close to the stock roll on the unwinding shaft 21, so as to adhere the working tape to the stock roll on the unwinding shaft 21.

Preferably, the second axis is parallel to the axis of the unwind shaft 21. The third axis is parallel to the second axis.

In some embodiments, the clamping assembly 42 includes a turntable 421, a fixed nip roller 422, and a movable nip roller 423. The turntable 421 is rotatably connected to one end of the second swing arm 41 about a third axis. The fixed nip roller 422 is mounted to the turntable 421, and the movable nip roller 423 is connected to the turntable 421 toward or away from the fixed nip roller 422. In this way, the clamping or unclamping of the working web is achieved by the movable nip roller 423 approaching or moving away from the fixed nip roller 422. That is, when the work material belt needs to be nipped, the movable nip roller 423 is moved toward a direction approaching the fixed nip roller 422, thereby nipping the work material belt between the movable nip roller 423 and the fixed nip roller 422. When it is necessary to unwind the work material tape after the work material tape is attached to the stock roll, the movable nip roller 423 moves in a direction away from the fixed nip roller 422, thereby unwinding the work material tape. And, when the working material tape is stuck to the stock roll, the rotary table 421 is rotated so that the cut working material tape is partially wrapped around the fixed nip roller 422 or the movable nip roller 423 and directed toward the stock roll for easy sticking. In order to better clamp the working material belt discharged from the unwinding shaft 21, the movable nip roller 423 and the fixed nip roller 422 are parallel to the second axis, that is, parallel to the unwinding shaft 21.

In particular, in the embodiment, one of the fixed nip roller 422 and the movable nip roller 423 is rotatable about its own axis. That is, when the fixed nip roller 422 and the movable nip roller 423 clamp the work material belt, the fixed nip roller 422 or the movable nip roller 423 can be driven to rotate around the axis thereof when the work material belt is pulled by a certain external force. In this way, the second swing arm 41 rotates to make the working material belt clamped by the movable clamping roller 423 and the fixed clamping roller 422 approach the material preparation roll on the unreeling shaft 21 until the fixed clamping roller 422 or the movable roller 423 wrapped with the working material belt is pressed against the material preparation roll, so that the working material belt is adhered to the material preparation roll. Then the material preparation roll rotates along with the unreeling shaft 21, so that the working material belt drives the fixed clamping roller 422 or the movable roller 423 to rotate around the axis of the fixed clamping roller 422 or the movable roller 423, the tail end of the working material belt is completely stuck to the material preparation roll, the phenomenon that the tail part of the working material belt is not stuck to the material preparation roll to form a free end, and the phenomenon that powder is easily dithered in the tape feeding process to affect the quality of products is avoided. Preferably, the fixed nip roller 422 is rotatable about its own axis. In this manner, the turntable 421 is rotated so that the severed working web is partially wrapped around the fixed nip roller 422 and toward the stock roll prior to affixing the working web to the stock roll.

In particular embodiments, the clamping assembly 42 further includes a fifth driver 424 disposed on the turntable 421. The fifth driving member 424 is drivingly connected to the movable roller 423 to drive the movable roller 423 toward and away from the fixed roller 422. More specifically, the movable pinch roller 423 is mounted to the driving end of the fifth driving member 424 through a movable pinch roller seat. Alternatively, the fifth driver 424 may be a jaw cylinder.

In particular, in the embodiment, the fixed clamping roller 422 can also be fixedly connected to the turntable 421 through the fixed clamping roller seat, so that the connection of the fixed clamping roller 422 is more stable.

Further, the clamping assembly 42 further includes a second elastic member disposed between the movable clamping roller seat and the fixed clamping roller seat, and the second elastic member is configured to provide a pre-tightening force that enables the movable clamping roller seat to have a movement trend away from the fixed clamping roller seat. Thus, the second elastic piece plays a role in buffering on the one hand, and the working material belt is prevented from being damaged due to rigid impact caused to the working material belt when the movable clamping roller 423 and the fixed clamping roller 422 clamp the working material belt. On the other hand, the fifth driving member 424 drives the movable nip roller 423 and cooperates with the fixed nip roller 422 to nip the work material belt while compressing the second elastic member. When the working material belt is required to be loosened, the fifth driving member 424 removes the force, and the movable nip roller 423 is moved away from the fixed nip roller 422 under the action of the second elastic member, thereby loosening the working material belt. Thus, the fifth driver 424 may employ a single pneumatic jaw cylinder, thereby reducing the pneumatic path and reducing the risk of pneumatic path entanglement.

In the embodiment, the tape splicing mechanism 40 further includes a fixing frame 44, a second slider 45, and a sixth driving element 46. The mount 44 is fixedly coupled to the mount 10. The second slider 45 is movably connected to the fixed frame 44 in a direction parallel to the second axis. The end of the second swing arm 41 remote from the clamping assembly 42 is rotatably connected to the second slider 45 about a second axis. The sixth driving member 46 is mounted on the fixing frame 44 and is drivingly connected to the second slider 45 to drive the second slider 45 to move in a direction parallel to the second axis. Thus, when it is necessary to clamp the working web discharged from the discharge spool 21, the sixth driving member 46 drives the second slider 45 to move in a direction parallel to the second axis (i.e., a direction parallel to the discharge spool 21), thereby driving the fixed nip roller 422 and the movable nip roller 423 of the nip assembly 42 to move in a direction parallel to the second axis so that the working web is interposed between the fixed nip roller 422 and the movable nip roller 423. The movable nip roller 423 is then moved toward a direction approaching the fixed nip roller 422 to effect pinching of the working web between the movable nip roller 423 and the fixed nip roller 422. Alternatively, the sixth driver 46 may be a translation cylinder.

Further, the fixing frame 44 has a second sliding rail 441, and the second slider 45 is slidably disposed on the second sliding rail 441. That is, the second slider 45 can slide along the second sliding rail 441.

In the embodiment, the belt receiving mechanism 40 further includes a swing shaft 47 and a seventh driving member 48. The pendulum shaft 47 is rotatably connected to the second slider 45 about its own axis. One end of the second swing arm 41, which is far away from the clamping assembly 42, is fixedly mounted on the swing shaft 47, so that the second swing arm 41 and the swing shaft 47 can rotate synchronously. The seventh driving member 48 is disposed on the second slider 45 and is in transmission connection with the pendulum shaft 47 to drive the pendulum shaft 47 to rotate around its own axis. It will be appreciated that the axis of the pendulum shaft 47 is the second axis. In this way, the swing shaft 47 is driven to rotate by the seventh driving member 48, so that the end of the second swing arm 41 remote from the clamp assembly 42 is rotated about the second axis. When the cut working tape needs to be adhered to the stock roll, the seventh driving member 48 drives the swing shaft 47 to rotate, so that the second swing arm 41 drives the clamping assembly 42 to rotate to the stock roll on the unwinding shaft 21, and simultaneously the turntable 421 rotates, so that the cut working tape partially wraps the fixed clamping roller 422 or the movable clamping roller 423 and faces the stock roll. Further, the output shaft of the seventh driving member 48 is drivingly connected to the pendulum shaft 47 through a coupling. Alternatively, the seventh driver 48 may be a motor.

Further, the clamping assembly 42 further includes an eighth driving member 49 and a transmission assembly, and the eighth driving member 49 is fixedly mounted with respect to the second slider 45. The transmission assembly is in transmission connection between the eighth driving member 49 and the turntable 421, so that the eighth driving member 49 drives the turntable 421 to rotate through the transmission assembly.

Further, the drive assembly includes a drive shaft 491. The transmission shaft 491 is in driving connection with the eighth driving member 49 and the turntable 421, respectively, to transmit the rotational movement output from the eighth driving member 49 to the turntable 421. Still further, the transmission assembly also includes a drive pulley 492, a primary drive pulley 493, a first drive belt 494, a secondary drive pulley 495, a driven pulley 496, and a second drive belt 497. The driving wheel 492 is mounted to the output shaft of the eighth driving member 49 to rotate in synchronization with the output shaft of the eighth driving member 49. The main driving wheel 493 is mounted to one end of the driving shaft 491 to rotate in synchronization with the driving shaft 491. The first belt 494 is interposed between the capstan 492 and the main driving wheel 493 to rotate the capstan 492 in synchronization with the main driving wheel 493. The secondary transmission wheel 495 is mounted to the other end of the transmission shaft 491 so as to rotate in synchronization with the transmission shaft 491. Driven wheel 496 is mounted to turntable 421 for synchronous rotation with turntable 421. A second drive belt 497 is interposed between the secondary drive wheel 495 and the driven wheel 496 to synchronize rotation of the secondary drive wheel 495 and the driven wheel 496. In this way, the output shaft of the eighth driving member 49 rotates to sequentially drive the driving wheel 492, the main driving wheel 493, the transmission shaft 491, the auxiliary driving wheel 495, the driven wheel 496, and the turntable 421. The transmission connection of the transmission shaft 491 to the eighth driving member 49 and the turntable 421 is not limited to a belt transmission, and may be realized by, for example, a gear transmission, a chain transmission, or the like in other embodiments, and is not limited thereto.

Further, the drive shaft 491 may be a hollow shaft. The transmission shaft 491 is coaxially sleeved outside the pendulum shaft 47 and is rotatable relative to the pendulum shaft 47. In this way, the transmission shaft 491 is sleeved with the swing shaft 47, so that the structure is more compact, the structure is simplified, and the occupied space is reduced. Alternatively, the transmission shaft 491 may be coaxially mounted outside the pendulum shaft 47 through a bearing.

In particular, in one embodiment, the taping mechanism 40 further includes a sliding plate 451 and a pendulum shaft mount 452. The sliding plate 451 is fixedly coupled to the second slider 45. The seventh driving member 48 is fixedly mounted on the sliding plate 451. The swing axle mount 452 is fixedly coupled to the slide plate 451. The pendulum 47 is rotatably connected to a pendulum mount 452 about its own axis. The transmission shaft 491 is sleeved outside the pendulum shaft 47. The eighth driving member 49 is fixedly mounted on the swing shaft mounting seat 452. Optionally, the second slider 45 may include two or more, so as to further improve the stability of the motion of the tape splicing mechanism 40.

In particular to one embodiment, the clamping assembly 42 further comprises a rotary shaft 425, the rotary shaft 425 being rotatably connected to the second swing arm 41 about its own axis. The rotary table 421 is fixedly coupled to the rotary shaft 425 to rotate in synchronization with the rotary shaft 425. Driven wheel 496 is fixedly mounted to shaft 425 for synchronous rotation with shaft 425. Further, the rotating shaft 425 is provided with a central hole along the axis thereof, and the air path of the fifth driving element 424 penetrates through the central hole of the rotating shaft 425 and is connected with the air joint. In this way, the air path winding caused by the rotation of the rotation shaft 425 can be avoided.

In some embodiments, the tape splicing mechanism 40 further includes a cutting driving member 431 and a cutter base 432. The cutting driving member 431 is fixedly mounted on the second swing arm 41, the cutter seat 432 is fixedly mounted on the driving end of the cutting driving member 431 and faces the clamping assembly 42, and the cutter 43 is mounted on one end of the cutter seat 432 facing the clamping assembly 42. The cutter driving member 431 drives the cutter seat 432 toward or away from the clamp assembly 42 to cause the cutter 43 to cut off the work material tape clamped by the movable clamp roller 423 and the fixed clamp roller 422 and then return to the original positions. Alternatively, the cutter driver 431 may be an air cylinder.

Referring to fig. 3, 13 and 14, in the embodiment of the present invention, the unreeling mechanism further includes a guiding assembly for guiding the working tape released from the unreeling shaft 21. The guide assembly includes a support base 71, a rotating wheel 72, a guide driving member 73, a rotating arm 76, and a guide roller 77.

The supporting seat 71 is fixedly connected to the mounting frame 10, and has a shaft hole for the first guide post 22 to pass through. Since the support base 71 is fixed relative to the mounting frame 10, the first guide post 22 is movable along its own axis relative to the mounting frame 10, and thus the first guide post 22 is movable along its own axis relative to the support base 71. The rotary wheel 72 is rotatably connected to the support base 71 about the axis of the shaft hole. The guide driving member 73 is disposed on the mounting frame 10 and is drivingly connected to the rotating wheel 72 to drive the rotating wheel 72 to rotate about the axis of the shaft hole. One end of the rotating arm 76 is fixedly connected to the rotating wheel 72, and the guide roller 77 is disposed at the other end of the rotating arm 76. Thus, the guiding driving member 73 can drive the rotating wheel 72 to rotate, so as to drive the rotating arm 76 and the guiding roller 77 to rotate along with the rotating wheel 72, and further adjust the position of the guiding roller 77 to guide the working material belt. Compared with the guide roller 77 in the prior art which moves along a straight line, the guide roller 77 is installed through the rotary structure in the embodiment, and the supporting seat 71 is sleeved on the first guide post 22 through the shaft hole, so that the structure is compact, the occupied space is reduced, and the use is more flexible.

In particular to the embodiment, the axis of the shaft hole is collinear with the axis of the unwinding shaft 21, so that the position adjustment of the guide roller 77 is more flexible and the occupied space is further reduced. Further, the axis of the guide roller 77 is parallel to the axis of the shaft hole, that is, the guide roller 77 is parallel to the unreel shaft 21, so that the material tape discharged from the unreel shaft 21 can be guided better.

In particular, in the embodiment, the rotary arm 76 extends lengthwise in the axial direction perpendicular to the shaft hole.

In some embodiments, the guide assembly further includes a guide drive wheel 74 and a guide belt 75. The guide driving wheel 74 is mounted to the output shaft of the guide driving member 73 to rotate in synchronization with the output shaft of the guide driving member 73. The guiding belt 75 is sleeved between the guiding driving wheel 74 and the rotating wheel 72, so that the guiding driving wheel 74 and the rotating wheel 72 synchronously rotate. That is, the guide driving member 73 drives the rotation wheel 72 to rotate by means of a belt transmission. Alternatively, the guide driving member 73 may be a motor.

In some embodiments, the support base 71 includes a mounting portion and a shaft portion fixedly coupled to one side of the mounting portion. The shaft hole sequentially penetrates the mounting portion and the shaft portion. The mounting portion is for fixed mounting to the mounting frame 10. The rotary wheel 72 is rotatably sleeved outside the shaft portion. In particular embodiments, the rotator wheel 72 may be journaled to the shaft portion by a bearing. The mounting portion may be mounted to the mounting frame 10 by, for example, welding, fastening with threaded fasteners, or the like.

Referring to fig. 15, based on the automatic reel changing device, the invention further provides a reel changing method, which includes the steps of:

s100: the work tape discharged from the reel 21 is cut off by the tape splicing mechanism 40, and then the cartridge on the reel 21 is discharged.

Specifically, the sixth driving member 46 drives the second slider 45 to move in a direction parallel to the second axis (i.e., a direction parallel to the axis of the unwinding shaft 21) so that the work material tape is interposed between the fixed nip roller and the movable nip roller. The fifth driving member then drives the movable nip roller toward the fixed nip roller to pinch the work material web. Then, the cutter is driven by the cutter driving member 431 to cut the work tape.

The second driving member 622 drives the rotating shaft 621 to rotate, so as to drive the gripper 624 to the gripping position, and the gripper 624 grips the cartridge on the unreeling shaft 21, i.e. the cartridge is fixed relative to the gripper 624. The unwind shaft 21 is then moved along its axis such that the cartridge is separated from the unwind shaft 21. Then, the second driving member 622 drives the rotating shaft 621 to rotate, so as to drive the gripper 624 to the discharging position, at this time, the gripper 624 releases the cartridge, and the cartridge falls into the storage area to be collected.

Further, to facilitate insertion of the work material strip between the fixed and movable nip rollers, the work material strip may be rotated by the rotating wheel 72 of the guide assembly to adjust the position of the work material strip with the guide roller 77 such that the work material strip is aligned with the gap between the fixed and movable nip rollers.

S200: the stock shaft 32 is rotated such that the docking end 320 of the stock shaft 32 is docked with the unwind shaft 21. The pusher 33 then pushes the stock roll on the stock shaft 32 to the unwind shaft 21.

Specifically, the stock shaft 32 is rotated such that the butt end 320 of the stock shaft 32 faces the unwind shaft 21. The unwind shaft 21 is then driven along its own axis toward the docking end 320 to bring the unwind shaft 21 into contact with the docking end 320 for docking. The pushing member 33 on the stock shaft 32 moves along the stock shaft 32, thereby pushing the stock roll on the stock shaft 32 onto the unreeling shaft 21.

S300: the cut-off working tape is connected to the stock roll on the unwind spool 21 by the tape splicing mechanism 40.

Specifically, the eighth driving member 49 drives the rotary table 421 to rotate so that a portion of the work material tape is wrapped around the fixed nip roller 422 or the movable nip roller 423.

The seventh driving member 48 drives the second swing arm 41 to rotate about the swing shaft 47, so that the fixed nip roller 422 or the movable nip roller 423 wrapped with a part of the work material tape contacts the preparation roll on the unwinding shaft 21, thereby adhering the work material tape to the preparation roll (for facilitating the connection of the material tape, the starting end of the preparation material tape of the preparation roll has a double-sided tape, and the double-sided tape is adhered to the work material tape). The unreeling shaft 21 rotates, so that the material preparation roll on the unreeling shaft 21 is driven to rotate, and the fixed clamping roller 422 or the movable clamping roller 423 is driven to rotate around the axis of the work material belt, so that the whole tail of the work material belt is adhered to the material preparation roll. Then, the fifth driving member drives the movable nip roller to move away from the fixed nip roller, thereby releasing the work material belt.

The sixth driving member 46 drives the second slider 45 to move in a direction parallel to the second axis, and the seventh driving member 48 drives the second swing arm 41 to rotate around the swing shaft 47, so that the tape splicing mechanism 40 returns to the original position.

Further, to avoid pulling the work material strip during the return of the strip splicing mechanism 40 to its original position, the work material strip may be lifted by the guide roller 77 of the guide assembly so that the work material strip is separated from the strip splicing mechanism 40. After the taping mechanism 40 returns to its original position, the guide roller 77 of the guide assembly brings the work material tape into position for unreeling.

In some embodiments, step S201 is further included after step S200: the stock roll on the unwind spool 21 is pushed into place along the axis of the unwind spool 21.

In one embodiment, the step S201 specifically includes: the unreeling shaft 21 moves in a direction away from the stock shaft 32 along its own axis, and the stock shaft 32 rotates so that the pushing piece 53 on the stock shaft 32 faces the unreeling shaft 21. The unwinding shaft 21 moves along its own axis in a direction approaching the stock shaft 32, so that the pushing member 53 pushes the stock roll on the unwinding shaft 21 into position (i.e., the stock roll contact positioning block 27). It will be appreciated that the movement of the unwind shaft 21 in a direction away from the stock shaft 32 along its own axis is for avoidance, preventing the stock shaft 32 from rotating such that the abutment 53 on the stock shaft 32 interferes with the abutment 53 as it is directed towards the unwind shaft 21.

In another embodiment, step S201 specifically includes: the unreeling shaft 21 moves in a direction away from the stock shaft 32 along its own axis. The pushing shaft 52 of the pushing mechanism rotates around its own axis to drive the pushing member 53 to rotate to the pushing position, i.e. the pushing member 53 is located between the stock shaft 32 and the unreeling shaft 21. The unwinding shaft 21 moves along its own axis in a direction approaching the stock shaft 32, so that the pushing member 53 pushes the stock roll on the unwinding shaft 21 into position (i.e., the stock roll contact positioning block 27).

When the docking end 320 of the stock shaft 32 is facing away from the unwind shaft 21, the docking end 320 of the stock shaft 32 may dock with a loading device, such as an AGV, to load one or more stock rolls onto the stock shaft 32.

Based on the automatic reel changing device, the invention further provides winding equipment. The winding apparatus comprises an automatic reel changer as described in any of the embodiments above.
