Description

  The present invention relates to a wet veneer veneer cut by a veneer lace, or a wet veneer veneer that has been dried by a veneer dryer, and then the continuous veneer veneer is once wound on a take-up reel. The present invention relates to a locking method in which a wound ball is not unwound from a veneer veneer at the final end when the wound ball is transferred to a rewinding place.

  Conventionally, a continuous veneer veneer cut by a veneer lace is usually conveyed by a conveyor to a veneer veneer winding position. At the veneer single plate winding position, the transport conveyor and the side drive roll having the same transport surface, and the winding reel rotatably supported at the position immediately above are maintained as pressed against each other. Yes. When the side drive roll is rotated at almost the same speed as the conveyor, the winding reel is passively driven by this rotational force in a line contact state, so that the veneer single plate conveyed on the conveyor is wound around the take-up reel. taking it.

  Usually, the width of the veneer single plate to be wound is 6 to 8 mm (1800 to 2400 mm), and the take-up reel and the side drive roll have a longer length in order to wind up these long veneer single plates. It is necessary. As described above, a continuous veneer single plate is wound around a take-up reel placed on a side drive roll, and is wound into a wound ball state by press-contact rotation of both.

  The wound ball that has been wound up is temporarily stored in a reeling deck installed at the start end of the winding position. That is, the winding of the veneer veneer is completed by the struts constituting the starting end of the reeling deck. Then, the wound ball that has been wound up moves up in the column via an elevating device provided on the column, and is transferred to the transfer rail of the wound ball stock area. Next, the next take-up reel is lowered onto the side drive roll from the return rail of the reel stock area and a new take-up is started.

  Usually this transfer rail has a slight downward slope towards the unwinding location located in front. For this reason, the wound balls are transferred forward while rotating while being stored in the wound ball stock area or as they are rolled by bearings at both ends of the take-up reel. Therefore, the veneer veneer once wound on the take-up reel is also unwound from its end portion on the way to the rewind location, and the intended purpose cannot be achieved.

  Conventionally, in order to prevent the above-mentioned rewinding phenomenon, the central part of the wound ball wound on the take-up reel is tied with a rope, or a plurality of terminal portions of a continuous veneer single plate are provided with tape or staples. For a long time. However, all of these conventional means are performed manually by the operator, and the working environment is poor. Therefore, the conventional means is not only extremely inefficient but also dangerous.

  In view of this, the present invention provides a wet veneer veneer cut by a veneer lace, or a wet veneer veneer that has been dried by a veneer dryer, and then a continuous veneer veneer is temporarily wound around a take-up reel. The present invention provides a locking method in which a wound ball is taken up, and the wound ball is not unwound from the last veneer veneer wound when the wound ball is transferred to a rewinding place.

Means for solving problems and their effects

In order to solve the above-described problem, the first method of locking the continuous veneer veneer wound ball of the present invention is as follows.
A continuous veneer single plate is wound on a take-up reel that is rotatably supported at a veneer single plate take-up position, and is wound into a ball. A plurality of yarn members are fed out from a plurality of locations spaced at an arbitrary interval in the core direction, and the winding member is rotated a plurality of times while the tip is wound around the winding ball to wind the yarn member around the outer surface of the winding ball, and then the yarn The member is separated and the wound ball is locked.

In order to solve the above problem, the second method of locking the continuous veneer veneer wound ball of the present invention is as follows.
A plurality of winding guide members are arranged opposite to each other at an arbitrary interval in the axial direction of the take-up reel that is rotatably supported at the winding position of the veneer single plate, and a continuous veneer single plate on the conveyor. Is wound along the curvature of a winding guide member that rotates at the same speed as the conveyor, on a part of the outer periphery of the winding reel located on the opposite side of the veneer veneer. A veneer single plate is wound on a reel, and at the end of winding to become a desired winding ball, a plurality of yarn members are fed out from a plurality of locations at arbitrary intervals in the axial center direction of the winding reel, and the tip is wound around The winding ball is rotated only a plurality of times while being wound around, and the thread member is wound around the outer peripheral surface of the winding ball, and then the thread member is separated to lock the winding ball.

  The wet veneer veneer cut by the veneer lace or the dried continuous veneer veneer dried by the veneer drier is conveyed to the veneer veneer winding position on the conveyor. In the veneer single plate winding position, a plurality of winding guide members are installed at arbitrary intervals in the axial direction of the winding reel. When the veneer single plate is wound, the winding guide member is in close contact with a part of the outer periphery of the take-up reel from the lower position of the take-up reel to the side opposite to the side where the veneer single plate is carried. Is done.

  Also, when winding the veneer single plate, this winding guide member is controlled to be almost the same as the transfer speed of the transfer conveyor, and the veneer single plate transferred from the transfer conveyor onto the take-up guide member follows the curvature of the take-up reel. It can be rolled in a surface state. In addition, even if the veneer veneer to be wound is after drying and the fiber has a higher rigidity than the wet veneer veneer, the winding guide member has a planar shape on the outer peripheral surface of the take-up reel. It is possible to wrap it following the above.

  Even in a continuous veneer veneer, the veneer veneer is likely to break due to cracks, cuts, etc. (it tends to occur more often in the dried veneer veneer), When the belt is loose, stable winding can be performed by winding the veneer single plate transferred onto the winding guide member as described above in a surface state following the curvature of the winding reel.

  In addition, the winding guide members are arranged in a plurality of rows with respect to the axis direction of the take-up reel. However, the winding guide members in each row are individually pressed under a certain pressure or pulled. I am nervous. Therefore, for example, even if the take-up reel is bent by its own weight or the veneer single plate has a difference in thickness, the take-up guide members in each row are maintained in the same tension state. For this reason, the winding guide member can apply substantially the same frictional force to the veneer single plate so as to follow the curvature of the winding reel, so that a stable winding operation can be performed.

  Then, a continuous veneer single plate is wound on a take-up reel that is rotatably supported at a veneer single plate winding position to form a ball, and the yarn member is placed at the end of winding to become a desired winding ball. Pull out. The thread member is fed out from a plurality of thread winding wheels at arbitrary intervals in the axial direction of the take-up reel. These spools are located in a direction orthogonal to the axial center direction of the take-up reel, that is, on an extension line of the outer peripheral surface of the wound ball, and the thread member is fed out from these spools. On the other hand, the thread member has its tip passed through a nozzle installed between the bobbin winder and the wound ball and is wound around the wound ball just before the end of winding, and is wound around the outer circumferential surface of the wound ball a plurality of times. Become.

  Preferably, a conduction hole is formed in the nozzle. This conduction hole guides the tip of the yarn member toward the outer circumference of the winding ball, and the compressed air is blown into the conduction hole so that the yarn member is fed out and is wound around the winding ball just before the end of winding. become. Then, after the yarn member is wound around the outer peripheral surface of the wound ball just before the end of winding a plurality of times, the yarn member is separated and cut by a yarn member separator provided in the nozzle to lock the wound ball.

  And the position where the said nozzle is installed in order to let out a thread | yarn member can be any position on the front side or the rear side with respect to the take-up reel. That is, when the nozzle is installed on the front side in the veneer veneer conveying direction, the yarn member is drawn out on a continuous veneer veneer wound as a wound ball, and the yarn fed out on the veneer veneer A member will be wound in a wound ball as it is. On the other hand, when the nozzle is installed on the rear side in the veneer veneer conveying direction, the yarn member is drawn out on the outer surface of the winding ball, and the tip of the yarn member is moved along with the rotation of the take-up reel. At the winding position, the thread member is directly wound on the winding ball.

  The thread member wound around the winding ball is wound a plurality of times, and then separated and cut by a thread member separator installed in the nozzle. Moreover, the termination | terminus part of a thread | yarn member will be latched in the state which hung down from the wound ball as a free end, or the state wound in the wound ball.

  A thread member separator made of a heating element such as a nichrome wire or a heating iron is installed in the nozzle, and is fused and separated by the heating element to lock the winding ball with its end portion as a free end. It becomes possible. In particular, the yarn member is usually constructed by twisting a plurality of fine single yarns, the fusing part by the heating element is bundled in a burned state, defibrated into a single yarn, and the end portion is wound. It is easy to maintain the hung-down state from the ball, and the collection work of the thread member in the subsequent process becomes easy.

  Further, in addition to the above-described aspect, the yarn member separator is configured by arranging a cutting blade having a sharp blade edge or a serrated blade edge in a direction intersecting the feeding direction of the yarn member at the separation cutting portion. Is also possible. And the thread member is cut | disconnected by sliding-contacting the cutting blade with respect to the thread | yarn member surface paid out, and a wound ball is latched.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
The conveyor 1 shown in FIG. 3 is configured such that a plurality of rows of belts 4 are stretched between a start end pulley 2 and a front end pulley 3 and can be rotated by driving a motor (not shown). Yes. In the vicinity of the terminal end portion of the conveyor 1, a pair of reel columns 6 are installed on the outer side perpendicular to the conveying direction. A reel receiver 8 that rotatably supports the take-up reel 7, and a reel presser 10 that holds the take-up reel 7 from above when the veneer single plate 9 is taken up by the take-up reel 7. Are installed facing each other inward to constitute a veneer single plate winding position 11. Further, suspension fluid cylinders 12 are respectively installed downward on the upper side portions of the pair of reel columns 6, and the chain and belt wound around the support portion 14 of the gantry 5 at the tip of the piston rod 13. One end of the support member 15 such as the like is connected, and the other end is attached to the support 16 of the reel column 6.

  A take-up guide member 17 for winding the veneer single plate 9 conveyed from the conveyer 1 around the take-up reel 7 from the lower position of the take-up reel 7 to the side opposite to the side into which the veneer single plate 9 is carried. The winding reel 7 is disposed so as to face the outer peripheral surface. In the winding guide member 17, as shown in FIG. 1, an endless belt 18 in which a belt is wound endlessly is arranged in a plurality of rows at an arbitrary interval in the axial direction of the winding reel 7. As shown in the figure, the winding reel 7 is disposed so as to face the outer peripheral side of the veneer single plate 9 on the opposite side to the carry-in side following the lower surface.

  As shown in FIG. 3, the winding guide member 17 is composed of a plurality of rows of endless belts 18 wound around pulleys positioned at a base end portion, an intermediate portion, an upper portion, and a distal end portion, respectively. That is, a plurality of front end pulleys 3 are attached to the shaft 20 of the front end pulley 3 of the transport conveyor 1 at an arbitrary interval in the axial direction, and the base end pulley 19 is connected to the front end pulley 3. They are arranged and installed within the interval. Further, an intermediate shaft 21 is supported in the vicinity of the front end of the gantry 5, and the pulley 22 at the intermediate portion extends in the axial direction of the intermediate shaft 21 so as to match the phase of the pulley 19 at the base end portion. Arranged and attached to each. Further, as shown in FIG. 2, an upper shaft 24 is rotatably supported between the upper portions of a plurality of support bodies 23 installed at the front end of the gantry 5 at right angles to the conveying direction. The pulleys 25 are arranged and attached in the axial direction of the upper shaft 24 so as to match the phases of the pulleys 19 and 22 at the base end portion and the intermediate portion. As shown in FIG. 2, the pulley 26 at the front end is rotatably supported within the distance between the front ends of the pair of support arms 27, and the rear ends of each pair of support arms 27 are connected to each other by connecting beams 28. Has been. Each of the pair of support arms 27 is formed with a support portion 32 that is pivotally supported by the intermediate shaft 21 in an intermediate region thereof, and a bearing surface attached to the support portion 32 slides between the intermediate shaft 21. It has a configuration.

Further, as shown in FIG. 3, a bracket 29 protruding downward is provided in the vicinity of the tip of the gantry 5, and a fluid cylinder 30 and a piston rod 31 are provided between the end of the bracket 29 and the connecting beam 28. And a plurality of pairs of support arms 27 interlocked by the connecting beam 28 follow the outer shape of the take-up reel 7 on which the veneer single plate 9 is taken up.
In the embodiment shown in FIG. 6, the auxiliary arms 27 a are extended from the end portions of the support arms 27, and the function of the connecting beam 28 is applied to the ends of the auxiliary arms 27 a provided on the pair of support arms 27. The connecting shaft 28a is provided. A fluid cylinder 30 and a piston rod 31 are interposed between the connecting shaft 28a and the mount 5, and a plurality of pairs of support arms 27 interlocked by the connecting shaft 28a and the auxiliary arm 27a are wound around the veneer single plate 9. It follows the outer shape of the take-up reel.

  Each of the endless belts 18 is configured in an endless shape by being wound in order of a pulley 19 at a base end, a pulley 22 at an intermediate portion, a pulley 25 at an upper portion, and a pulley 26 at a distal end. The conveyor 33 and the winding guide member 17 are rotationally controlled at substantially the same speed by passively rotating the motor 33 installed in the machine. Further, when the pair of support arms 27 are turned by the following fluid cylinder 30 in the direction of the take-up reel 7 around the support portion 32 placed on the intermediate shaft 21 via the bearing surface, each pair of support arms 27 is turned. The pulley 26 at the tip located at the tip of the support arm 27 is in contact with the outer periphery of the take-up reel 7, and the take-up guide member 17 is pressed against a part of the outer periphery of the take-up reel 7 in a planar shape following the curvature. State.

  Further, the winding guide member 17 is provided with a rotating pulley 37 that is pressed or pulled under the pressure in the endless belt 18 constituting the winding guide member 17 while allowing the rotational force of the winding guide member 17. A constant tension is applied to the endless belt 18 of the winding guide member 17 to maintain the tension state. That is, as shown in FIGS. 3 to 6 and FIG. 8, an L-shaped shape corresponding to the endless belt 18 constituting the winding guide member 17 is arranged in the axial direction of the shaft 38 supported on the mount 5. A lever 39 is attached, and the rotary pulley 37 is rotatably supported at an intermediate position where the lever 39 protrudes. Further, a tension fluid cylinder 40 is pivotally supported at the end of the bracket 29 projecting downward from the vicinity of the tip of the gantry 5, and the piston rod 41 of the tension fluid cylinder 40 is connected to the other end of the lever 39. It is attached. Therefore, the rotary pulley 37 presses the endless belt 18 constituting the winding guide member 17 under a certain pressure, and the rotary pulley 37 shown in FIG. By pulling, the winding guide member 17 is in a tension state.

  Note that the L-shaped lever 39 is not provided for each L-shaped lever 39 as a shaft for rotatably supporting the rotary pulley 37, but is inserted into an intermediate position between the rotary levers 39 located at both ends. A rotating pulley 37 is rotatably supported in accordance with the number of rows of endless belts 18 constituting the winding guide member 17 in the axial direction of the shaft, which is constituted by a single shaft (not shown). It is also possible to attach the other end to the piston rod 41 of the tension fluid cylinder 40. According to this, each rotation pulley 37 can act integrally with the winding guide member 17 to be in a tension state, and the winding guide member 17 is in a state along the curvature of the winding reel 7. be able to. Further, when the self-weight deflection of the take-up reel 7 occurs or there is a difference in thickness of the veneer single plate 9, an L-shaped lever 39 is attached to each endless belt 18 constituting the take-up guide member 17. If the tensioning fluid cylinders 40 for applying a certain pressure to the individual endless belts 18 are installed, the winding guide members 17 in each row are maintained in the same tensioned state, and the winding reels 7 Almost the same frictional force can be applied to the veneer single plate 9 at any part in the axial direction.

  When winding the veneer veneer 9, first, fluid is supplied to the front port of the suspension fluid cylinder 12 attached to the fixed reel column 6, and the gantry 5 is moved to the carry-in side of the veneer veneer 9. With the axis of the start end pulley 2 of the conveyor 1 positioned as a fulcrum, the tip of the gantry 5 is swung upward. Therefore, the front end of the gantry 5 turns together with the transport conveyor 1 and the winding guide member 17, and the winding guide member 17 comes into contact with the lower surface of the winding reel 7 that is rotatably supported by the reel receiver 8. Next, the fluid cylinder 30 for follow-up and the fluid cylinder 40 for tension are actuated so that the endless belts 18 constituting the take-up guide member 17 follow the lower surface of the take-up reel 7 on the carry-in side of the veneer single plate 9. It moves to the outer peripheral side surface on the opposite side so as to be in close contact with each other, and is maintained in a tension state. (See Figure 3)

  If it will be in this state, the veneer veneer 9 conveyed from the front | former process will move on the conveyance conveyor 1, and will be rotated by controlling the outer periphery of the lower surface of the take-up reel 7, and substantially the same speed as the conveyance conveyor 1. It can reach between the endless belt 18 of the winding guide member 17. The veneer single plate 9 supplied in a continuous state may be a wet state cut by a veneer lace (not shown) or a dry state dried by a veneer dryer (not shown).

  The endless belt 18 of the winding guide member 17 is brought into close contact with a part of the outer periphery of the winding reel 7 from the lower position of the winding reel 7 to the side opposite to the side where the veneer single plate 9 is carried. Therefore, the veneer single plate 9 is wound in a surface state following the curvature of the take-up reel 7 by the frictional force generated with the driving of the take-up guide member 17. Even if the veneer veneer 9 to be wound is dried and the rigidity of the fiber is stronger than that of the wet veneer veneer 9, the outer periphery of the take-up reel 7 is taken up by the take-up guide member 17. It is possible to wind the surface following the surface.

  In addition, the veneer veneer 9 to be wound is easy to break due to cracks, cuts, etc. (they tend to occur on the veneer veneer 9 after drying), or the central part of the wound ball in the winding process is loosened Even so, as described above, the winding guide members 17 in a plurality of rows are in close contact with the veneer single plate 9 in a planar shape, so that stable winding can be performed. That is, in the course of winding the veneer single plate 9, the individual endless belts 18 constituting the winding guide member 17 are substantially separated for each endless belt 18 by the lever 39, the rotating pulley 37, and the fluid cylinder 40 arranged individually. When the same pressure is applied and the tensioned state is maintained, for example, even if the self-deflection of the take-up reel 7 has occurred or the veneer single plate 9 has a difference in thickness, the take-up guide for each row It is possible to apply substantially the same frictional force to the veneer single plate 9 at any portion in the axial direction of the take-up reel 7 while maintaining the member 17 in the same tension state.

As the veneer veneer 9 is wound on the take-up reel 7 and the diameter of the wound ball 35 increases, the tip of the gantry 5 increases in diameter of the wound ball 35 with the shaft of the start end pulley 2 of the conveyor 1 as a fulcrum. It will be turned downward by the amount. (See Figure 4)
That is, since the position of the reel receiver 8 that supports the winding reel 7 is fixed, the winding ball 35 overcomes the fluid pressure of the suspension fluid cylinder 12 by an increase in its diameter, and the winding guide member 17. The cradle 5 is pushed down via Further, as the diameter of the winding ball 35 increases, the position of the pulley 26 at the tip of the winding guide member 17 also moves in the clockwise direction from the position shown in FIGS. Overcoming the fluid pressure will gradually get up. Further, as the diameter of the winding ball 35 increases, the position of the rotating pulley 37 that presses and tensions the winding guide member 17 individually also overcomes the fluid pressure of the tensioning fluid cylinder 40 and is individually displaced. Will do. These are also apparent from the comparison between the winding start position of the veneer single plate 9 shown in FIG. 3 and the winding advance position shown in FIG.

  In addition to the above-described form, the winding guide member 17 has pulleys located at both ends of the veneer single plate 9 as shown in FIG. It is also possible to configure with a plurality of rows of endless belts 18 wound around each. That is, a base end shaft 46 is rotatably supported in front of the shaft 20 of the front end pulley 3 of the conveyor 1 at a position below the winding position of the veneer single plate 9, and the base end shaft 46 extends in the axial direction. A linkage pulley (not shown) is attached to a position in phase with the tip pulley 3 and a linkage conveyor 47 is wound around. On the other hand, a plurality of base end pulleys 48 are attached to the base end shaft 46 at an arbitrary interval in the axial direction. A pair of support arms 49 that are bent upwardly toward each other are rotatably supported. Then, a shaft is provided within the distance between the tips of the pair of support arms 49, and small-diameter tip pulleys 50 are rotatably supported on the shafts, and the base-end pulley 48 and the small-diameter tip pulley 50 are interposed between them. The endless belt 18 such as a belt is stretched over, and arbitrary positions of the support arms 49 are integrally connected by a connecting beam 51, and both ends of the connecting beam 51 are pivotally supported by the frame 5. The piston rod 31 is attached.

  Each endless belt 18 has a belt-like shape that is endlessly stretched between the base end pulley 48 and the front end pulley 50, but is not stretched between pulleys of equal diameter. 48 has a larger diameter than the pulley 50 at the tip. Therefore, there is a margin when the endless belt 18 is pressed against the lower outer periphery of the take-up reel 7 by the difference in radius between the pulleys 48 and 50, and the endless belt 18 is placed on the lower end of the outer periphery of the take-up reel 7 with a certain length. Can be pressed with an arcuate surface. By pressing in this planar shape, the planar contact area between the endless belt 18 and the lower part of the take-up reel 7 can be increased and more frictional force can be generated, and the veneer single plate 9 can be applied to the take-up reel 7. Can be stably wound. Further, since the support arm 49 that supports the base end pulley 48 and the front end pulley 50 is bent upward from the intermediate region toward the front end, the diameter of the wound ball 35 increases as the winding proceeds. As a result, inconveniences such as interference between the lower end of the upper track of each endless belt 18 and the upper end of the support arm 49 and rotation of the endless belt 18 are avoided, and the veneer single plate to the take-up reel 7 is avoided. 9 winding is ensured.

  In the embodiment shown in FIGS. 3 to 4, the gantry 5 is swiveled by a suspension fluid cylinder 12, but the position of the reel receiver 8 can be raised and lowered as in the embodiment shown in FIG. It is also possible to do. Specifically, the frame 5 and the winding guide member 17 that is rotatably supported can be fixed, and the reel receiver 8 can be moved up and down together with the reel support 6. As another embodiment, as shown in FIG. 5, reel receivers 8 at both ends supporting the take-up reel 7 are coupled to a step shaft 52, and a step shaft is connected by a motor 53 connected to the step shaft 52. The reel receiver 8 may be movable up and down with respect to the reel column 6 by making 52 rotatable. The reel support 6 is provided with a belt-like line sensor 54 for detecting the diameter of the wound ball 35. The line sensor 54 detects the thickness of the veneer single plate 9 to be wound, and the take-up reel 7 rotates once. Each time the thickness of the stepped shaft 52 is stepped by the motor 53 by the detected thickness, the reel receivers 8 at both ends can be raised.

  Further, as an embodiment in which the pedestal 5 and the like can be swiveled with respect to the reel column 6 as shown in FIG. 8, the pedestal 5 may be supported at a constant pressure by a balance weight 55 instead of the fluid cylinder 12 of FIG. Is possible. The balance weight 55 can be moved up and down along the pair of reel columns 6, and a support member 15 such as a chain and a belt attached to the balance weight 55 includes a balance pulley 56 above the reel column 6 and the frame. 5 is wound around a support portion 14 composed of a pulley attached to 5, and its end is fixed to a support 16 of the reel column 6. Therefore, the support member 15 pulled downward by the balance weight 55 that receives the gravity changes the direction to lift the support portion 14 of the gantry 5, and the gantry 5 takes up the take-up guide member 17 with a certain pressure. 7 can be pressed.

  Further, as shown in FIGS. 3 and 4 and FIGS. 6 and 7, a plurality of thread member feeding mechanisms 61 for feeding the thread member 60 toward the axial direction of the take-up reel 7 are installed at an arbitrary interval. As shown in FIG. 2, the yarn member feeding mechanism 61 is a nozzle for feeding the yarn member 60 into the winding ball 35 within a substantially intermediate space of the support arm 27 of the winding guide member 17. 62 is attached.

  In the winding according to any of these embodiments, the continuous veneer single plate 9 is wound around the winding reel 7 to increase the diameter of the winding ball 35, and the thread member 60 is replaced with the thread member just before the end of the winding. A plurality of rows are fed out by the feeding mechanism 61 and the leading ends thereof are wound around the winding balls 35. The thread member 60 once wound is wound around the outer peripheral surface by rotating the winding balls 35 a plurality of times.

  As described above, a plurality of the thread member feeding mechanisms 61 are installed in the axial direction of the take-up reel 7 at an arbitrary interval, and the attachment position of the thread member feeding mechanism 61 is relative to the take-up reel 7. Any position on the front side or the rear side is possible. For example, when the yarn member feeding mechanism 61 is installed on the front side in the conveying direction of the veneer veneer 9, the yarn member 60 is fed onto the continuous veneer veneer 9 wound as the winding ball 35, The thread member 60 fed out on the veneer single plate 9 is wound on the winding ball 35 as it is. On the other hand, when the yarn member feeding mechanism 61 is installed on the rear side in the conveying direction of the veneer veneer 9, the yarn member 60 is fed onto the outer surface of the winding ball 35 to rotate the take-up reel 7. Along with this, the tip of the veneer single plate 9 reaches the winding position, and the thread member 60 is wound on the winding ball 35 as it is.

  In the embodiment in which the thread member feeding mechanism 61 is installed on the rear side with respect to the take-up reel 7, the nozzle 62 for feeding the thread member 60 is arranged at an arbitrary interval in the lateral direction of the take-up reel 7 as shown in FIG. A plurality of the nozzles 62 are arranged, and the nozzles 62 are attached to a horizontal frame 63 that extends over a substantially intermediate position of the support arms 27. Thus, the support arm 27 to which the nozzle 62 is attached via the horizontal frame 63 can be moved by the fluid cylinder 30 for each of a plurality of sets. Therefore, the nozzle 62 attached to the horizontal frame 63 is moved by the fluid cylinder 30. It can be moved. For this reason, the nozzle 62 for feeding out the thread member 60 can move together with the support arm 27 in accordance with the size of the winding ball 35, and the distance from the take-up reel 7 changes unlike the fixed nozzle 62. Therefore, the fed yarn member 60 can be reliably wound around the winding ball 35 regardless of the finished size of the winding ball 35.

  Further, as in the embodiment of FIG. 6 showing the detailed structure of the thread member feeding mechanism 61, the thread member 60 fed from the nozzle 62 is stored in a thread winding wheel 64, and this thread winding wheel 64 is supported from the reel column 6 to the support frame. 65 is protruded and stored in a case 66 attached to the support frame 65. The yarn member 60 drawn out from the spool 64 of the case 66 is guided to the nozzle 62 via the yarn breakage detecting portion 67, and is drawn out from the nozzle 62 onto the winding ball 35 just before the winding is finished.

  The nozzle 62 for feeding out the thread member 60 is provided with a tubular conduction hole 70 as shown in FIG. 9, and an insertion portion 71 of the thread member 60 is disposed at the base of the conduction hole 70. The insertion portion 71 of the thread member 60 is provided with a compressed air outlet 72 that blows out toward the conduction hole 70. A thread member separator 73 for cutting the thread member 60 is disposed in the middle of the nozzle 62. In addition, high pressure air from a compressor (not shown) is sent to the compressed air outlet 72, or the blower 74 is continuously connected to the compressed air outlet 72 as in the embodiment of FIG. May be installed. In particular, when power is used as the thread member separator 73, the blower 74 that can be controlled with the same power is easier to handle.

  The thread member separator 73 of the embodiment shown in FIG. 9A includes a heater 75 having a hole through which the thread member 60 can be inserted at the center, and the thread member 60 made of a thermoplastic material has a conduction hole 70. The hole of the heater 75 is also penetrated when penetrating, and when the heater 75 is energized when the yarn member 60 is cut, the yarn member 60 can be cut by this heat. Further, in the thread member separator 73 of the embodiment shown in FIG. 9B, a cutting blade 76 is disposed in a direction intersecting with the conduction hole 70 of the thread member 60, and this cutting blade 76 is driven by a solenoid 77. It is like that. The cutting blade 76 has a sharp blade edge or a serrated blade edge, and when cutting the thread member 60, when the solenoid 77 is energized, the cutting blade 76 can be cut by being in sliding contact with the thread member 60. .

  The yarn member feeding mechanism 61 is used to confirm the absence of the veneer veneer 9 that is continuously fed on the conveyor 1 immediately after the winding of the winding ball 35, or from the veneer race to the end of the veneer veneer 9 Is driven when the end of the continuous veneer veneer 9 is detected. Based on this detection command, the blower 74 is energized to supply compressed air into the conduction hole 64 of the nozzle 62. Allow to blow. Since the tip of the thread member 60 is guided in advance from the insertion portion 71 to the conduction hole 70, the thread member 60 is fed out from the thread winding wheel 64 by the force of the wind and passes through the conduction hole 70 provided in the nozzle 62. It passes through the outer periphery of the wound ball 35 and is wound around the wound ball 35 just before the end of winding. Then, the thread member 60 is wound around the outer peripheral surface of the winding ball 35 just before the end of winding a plurality of times, and then separated and cut by a thread member separator 73 provided in the nozzle 62. At this time, the end portion of the thread member 60 is locked in a state where it is hung from the winding ball 35 as a free end (see FIG. 10) or in a state where it is caught in the winding ball 35 (see FIG. 10).

  The heater 75 of the thread member separator 73 can be composed of a heating element such as a nichrome wire or a heating iron. The heater 75 is installed on the thread member conveyance path surface of the conduction hole 70, and is energized when the thread member 60 is separated, that is, when the thread member 60 is wound around the outer circumferential surface of the winding ball 35 a plurality of times. Thus, the thread member 60 is fused and separated. The terminal portion of the thread member 60 that has been separated by fusing becomes a free end, and is in a state where it hangs down while retaining the wound ball. In particular, the yarn member 60 is usually formed by twisting a plurality of fine single yarns, the fusing part by the heating element 65 is bundled in a burned state, defibrated into a single yarn, and terminated. Can be easily maintained in a state of hanging from the winding ball 35, and the collection work of the thread member 60 in the subsequent process is facilitated.

  In addition to the above-described aspect, the thread member separator 73 is constituted by a cutting blade 76 whose separation cutting portion is arranged in a direction intersecting with the feeding direction of the thread member 60, and with respect to the surface of the thread member 60 to be fed. Then, the solenoid 77 is driven to slidably contact the cutting edge of the cutting blade 76 to cut the yarn member 60, and the winding ball 35 is locked with the end portion thereof being a free end.
