Example one

Referring to fig. 1-3, the embodiment discloses a stacker, which is mainly used for stacking bar materials 200, and specifically includes a detection device 1, where the detection device 1 is configured to detect the end face size of the bar materials 200; a stock device 2, the stock device 2 being configured to store the detected bar 200; a stacking device configured to selectively load the bars 200 in the storing device 2 and arrange the bars in layers; a material frame device 5 configured to stack the layered bar stock 200 of the stacking device.

The stacker further comprises an electric control device configured to control selective material taking of the stacker so that the total width of the layered bar material 200 is within a preset range.

The stacking machine further comprises a machine frame 100, and the detection device 1, the storage device 2, the stacking device and the material frame device 5 are all arranged on the machine frame 100. Furthermore, the electric control device is also used for controlling the time sequence action of each device of the integrated stacking machine, so as to realize the automatic operation of the stacking flow. Further, the stacking machine further comprises a display device, and the display device is configured to be capable of displaying the operation state of each device, so that the stacking process can be monitored manually in real time.

The embodiment further provides a stacking method, in which the stacking machine is used to stack the bar stock 200, and the method specifically includes the following steps:

s1: putting the bar 200 into the detection device 1 to detect the end face size of the bar 200;

s2: the detected bar stock 200 is stored by the material storage device 2;

s3: according to the step S2, the stacking device selectively takes materials from the material storage device 2 and arranges the bar materials 200 into layers;

s4: pushing the arranged layered bar stock 200 into a material frame 300 of a material frame device 5;

s5: and repeating the steps S3 and S4 to complete the stacking of the layered bar stock 200 in the material frame 300.

The total width of each layer of bar stock 200 should be within a certain preset range, so that the bar stock 200 can be just stacked in the material frame 300 without shaking and loosening, and the regularity and stability of stacking are ensured. Therefore, in step S2, the end face dimension data of the bar stock 200 stored in the stock device 2 forms a database; in step S3, the electronic control device performs data analysis on all the bars 200 in the database, so that the total width of each layer of bars 200 is within a preset range after the bars 200 selected by the stacking device are arranged into layers. In this embodiment, the bar material 200 to be stacked has a regular hexagonal prism structure, the end surface of which has a regular hexagonal shape, and the storage space of the material frame 300 has a generally rectangular parallelepiped structure. Therefore, for the bars 200 with the regular hexagonal prism structure, in order to stack more bars 200 as much as possible, the total number of the bars 200 of the two adjacent layers of bars 200 should be different by 1, and the number of the bars 200 at the bottom layer is greater than that of the bars 200 at the last but one layer, so that except for the bars 200 at the top layer and the bottom layer and the edge bars 200 of the layered bars 200 with more total number, each bar 200 is arranged between the two adjacent bars 200 at the lower layer and the upper layer, and the side surfaces of the bars 200 are mutually attached, which is beneficial to the regular arrangement of the bars 200, effectively utilizes the regular hexagonal prism structure of the bars 200 to improve the space utilization rate of the material frame 300, and can avoid the problems that the bars 200 shake in the material frame 300, cause disordered arrangement, and are not beneficial to later transportation and use. For the bars 200 with a regular hexagonal prism structure, the total number of the bars 200 in each layer can be 72 or 71, and of course, the total number of the bars 200 in each layer and the total width thereof can be adjusted according to the structure of a specific product and the size of the storage space of the material frame 300, which is just an example.

The bar material 200 has two end faces arranged along the axial direction, and due to the manufacturing error problem of the bar material 200, the sizes of the end faces of different bar materials 200 are different, and the sizes of the two end faces of the same bar material 200 arranged along the axial direction are also different, so that the step S1 includes the steps of:

s11: the detection device 1 detects the dimensions of both end faces of the bar 200 provided in the axial direction.

The sizes of the two end faces of the same bar 200 arranged along the axis direction are detected and recorded into the database, so that when the bar 200 is selected in the step S3, the sizes of the two end faces of the bar 200 are considered, and the total width of the two end faces of each layer of the bar 200 is controlled within a preset range.

Further, between steps S3 and S4, the stacking method further includes the steps of:

s31: after the bar stock 200 in the stock device 2 is taken away, the corresponding size data of the bar stock 200 is eliminated, and meanwhile, a new bar stock 200 is stored, the size data is continuously recorded into the database, and the database is updated.

The arrangement of the step S31 enables the database of the storage device 2 to be continuously updated, the database capacity is unchanged, sufficient bar material 200 size data is maintained, the selectivity of the stacking device is increased, the stacking device can obtain a proper bar material 200 from the new database, the feeding continuity of the storage device 2 is ensured, and the stacking efficiency is improved.

According to the material stacking machine and the material stacking method, materials are selectively taken through the material stacking device, so that the total width of each layer of stacked bars 200 is within a preset range, meanwhile, the adjacent bars 200 can be fully attached, stable stacking of the bars 200 in the material frame 300 is achieved, and convenience in later-stage transportation and use is improved. It should be noted that the stacker in this embodiment is mainly used for stacking the bars 200 having a regular hexagonal prism structure, but is not limited to stacking the bars 200 having a regular hexagonal prism structure, and may also be used for stacking the bars 200 having other structures, such as a rectangular parallelepiped, a regular triangular prism, and the like, and the specific stacking principle is similar to that in this embodiment, the description is mainly given by taking the bars 200 having a regular hexagonal prism structure as an example.

In specific implementation, when the tension spring 414 on the connecting seat 416 is in the limit tension state, the eighth driving module 418 drives the connecting seat 416 to move a certain distance along the arrangement direction of the bars 200, so that the tension spring 414 on the connecting seat 416 is reset, and at this time, when the stop top plate 413 moves backwards again, the tension spring 414 is stretched again, and the stop top plate 413 continues to exert the stop function. Through the cooperation of the reverse stopping mechanism and the elastic stopping mechanism, the layered bar materials 200 in the cartridge clip 410 are always kept tightly attached without shaking or rolling until the final layered arrangement is completed.

Further, referring to fig. 12, the clip loading mechanism 41 further includes a second laser displacement sensor 419 disposed on the clip 410, which cooperates with the first laser displacement sensor 313 to detect the total width of the entire layered bar material 200, and when the total width reaches a predetermined range, the feeding device 3 stops feeding the bar material 200. Specifically, the second laser displacement sensor 419 is used to coordinate the first bar 200 entering the clip 410, and the first laser displacement sensor 313 is used to coordinate the last bar 200 entering the clip 410, so as to measure the total width of the whole layered bar 200.

Referring to fig. 12 and 13, the pushing mechanism 42 includes a push plate 421 and a ninth driving module 422, the push plate 421 is disposed opposite to the layered bar 200 in the clip loading mechanism 41, and the ninth driving module 422 is used for driving the push plate 421 to abut against an end surface of the layered bar 200, so as to push the entire layered bar 200 to move toward the inside of the material frame 300. The ninth drive module 422 may be selected to be a pneumatic module. Further, the width of the push plate 421 should be consistent with the total width of the layered bar 200 to ensure that all the bar 200 of the layered bar 200 are abutted, so that the total width of the layered bar 200 can be varied according to the size and structure of the stacked products, and at least two push plates 421 with different widths and corresponding ninth driving modules 422 can be optionally provided to respectively push the layered bars 200 with different total width sizes. In this embodiment, for the bar material 200 having a regular hexagonal prism structure, the number of the bar materials 200 arranged in two adjacent layers differs by 1, so the total width of the layered bar material 200 mainly has two sizes, and accordingly, the number of the push plate 421 and the number of the ninth driving module 422 are both set to two. Further, since the positions of the frame 300 and the clip loading mechanism 41 on the frame 100 are relatively fixed, the clip device 4 further includes a tenth driving module 46 for driving the pushing mechanism 42 to move along the width direction of the layered bar material 200, so that the pushing plates 421 with different width dimensions correspond to the layered bar material 200 with corresponding total width, and further the layered bar material 200 is pushed into the same frame 300.

Referring to fig. 12, the cartridge clip device 4 further includes a first module fixing plate 43 and a second module fixing plate 44 which are parallel to each other and are disposed at an interval, the second module fixing plate 44 is used for supporting the material pushing mechanism 42, and the ninth driving module 422 is disposed on the second module fixing plate 44; the first module fixing plate 43 is disposed on the frame 100 for supporting the entire cartridge clip device 4, and the cartridge clip loading mechanism 41, the eighth driving module 418 and the tenth driving module 46 are disposed on the first module fixing plate 43. In this embodiment, the push plate 421 can push the bar material 200 into the frame 300 along the first direction under the driving of the ninth driving module 422; the pusher mechanism 42 is movable in the second direction by the tenth drive module 46.

Further, the width of the clip 410 is smaller than the length of the bar 200, so that the two free ends of the bar 200 can protrude out of the clip 410, which is convenient for pushing the bar 200 by the conveying clamping jaw 311 and also convenient for pushing the push plate 421 against the bar 200 to complete the pushing. Specifically, referring to fig. 11, the upper clamping jaw 3111 and the lower clamping jaw 3112 are both U-shaped, the bar stock 200 is clamped at a free end of the U-shaped, and the width of the clip 410 is smaller than the distance between the two free ends of the U-shaped, so that the conveying clamping jaw 311 is not interfered when pushing the bar stock 200 into the clip 410, and pushes the bar stock 200 into the clip 410 along the arrangement direction until the bar stock 200 is attached to the nearest bar stock 200. Further, the sides of the upper and lower covers 4101, 4102 that contact the bar 200 are coated with plating to prevent the upper and lower covers 4101, 4102 from scratching the bar 200.

Further, since the length and the size of the bars 200 are substantially the same, in order to ensure that the end surfaces of the plurality of bars 200 are flush when the stacking device performs the layered arrangement, the feeding clamping jaw 221 and the blanking clamping jaw 231 should clamp a specific part of the bars 200, so that the problem that whether the end surfaces are flush is not considered when each layer of the bars 200 are arranged. In order to achieve the above purpose, referring to fig. 6 and 9, an abdicating groove 214 is formed at a side of each accommodating groove 213 of the fixing plate 111, the sliding plate 14 and the storage tray 212 of the detecting device 1, the position of the abdicating groove 214 is kept consistent with that of the bar stock 200, the feeding clamping jaw 221 and the blanking clamping jaw 231 extend into the corresponding abdicating groove 214 to clamp a fixed position of the bar stock 200, further, each bar stock 200 keeps the same displacement and working position in the process that the bar stock 200 is transferred from the blanking clamping jaw 231 to the rotating clamping jaw 321 and is pushed to the conveying clamping jaw 311 by the rotating clamping jaw 321, and thus end faces of a plurality of bar stocks 200 entering the cartridge clip 410 are kept flush.

EXAMPLE five

The present embodiment provides a material frame device that can be used in the fourth embodiment to stack the layered bar materials 200 arranged by the clip device 4 layer by layer. Referring to fig. 17 and 18, the material frame device 5 includes: a material frame 300, which is provided with an opening, the opening is arranged towards the cartridge clip loading mechanism 41, and is used for stacking the layered bar materials 200 pushed by the material pushing mechanism 42; the material frame support frame 51 is arranged on the rack 100; the eleventh driving module 52 is disposed on the frame support 51 for driving the frame 300 to move up and down along the stacking direction. In this embodiment, the stacking direction is a vertical direction (third direction), which is perpendicular to the pushing direction of the pushing mechanism 42. In specific implementation, since the position of the clip loading mechanism 41 on the rack 100 is fixed, the height of the pushing mechanism 42 is the same when pushing the layered bar material 200 each time, and therefore, the height of one layer of the bar material 200 needs to be adaptively lowered for each pushing of the frame 300, so that the next layer of the bar material 200 can be stacked on the previous layer of the bar material 200 in the frame 300.

Referring to fig. 18, the material frame device 5 further includes a material pressing mechanism 53, which specifically includes a pressing plate 531 disposed inside the material frame 300 and a twelfth driving module 532 disposed on the material frame support frame 51, where the twelfth driving module 532 is configured to drive the pressing plate 531 to move along a third direction, so that the pressing plate 531 abuts against the bar material 200 in the material frame 300; through the arrangement of the material pressing mechanism 53, the bar material 200 can be pressed after the bar material 200 is pushed into the material frame 300, the tilting or displacement of the bar material 200 due to mutual extrusion is avoided, and the stability of the bar material 200 in the material frame 300 is fully ensured. Further, when the pushing mechanism 42 continuously pushes the material, the pressing plates 531 need to be raised to avoid obstructing the stacking of the next layer of bar materials 200, but when the pressing plates 531 are raised, the stability of the bar materials 200 is difficult to ensure, therefore, at least two pressing mechanisms 53 are provided, and are arranged at intervals along the pushing direction of the pushing mechanism 42, when a new layer of bar materials 200 is pushed into the material frame 300, the pressing plates 531 near the clip loading mechanism 41 are raised in advance, so that the new layer of bar materials 200 can be stacked on the previous layer of bar materials 200, along with the continuous pushing, when the new layer of bar materials 200 moves to the subsequent pressing plates 531, the pressing plates 531 are raised to provide a stacking space for the new layer of bar materials 200, meanwhile, the previous pressing plate 531 is lowered to press the bar materials 200 being pushed in, the pushing mechanism 42 continues to be pushed, until the layer of bar materials 200 is stacked, all the pressing plates 531 press the upper part of the new layer of bar, by analogy with … …, the plurality of pressing mechanisms 53 are arranged such that at least one pressing plate 531 presses the bar 200, thereby ensuring the stability of the stacking of the bar 200 and not affecting the stacking process. Optionally, in this embodiment, two pressing mechanisms 53 are provided.

The material frame device 5 further comprises a material frame supporting plate 54, the material frame 300 is placed on the material frame supporting plate 54, and the material frame supporting plate 54 is connected with the output end of the eleventh driving module 52, so as to drive the material frame 300 to lift. In specific implementation, after one material frame 300 is fully stacked, the stacked material frame 300 is unloaded by an external machine, and then a new material frame 300 is placed, so that loading and unloading of the material frame 300 are realized. Further, referring again to fig. 17 and 18, the frame rails 55 are provided on the rack 100, and the frame 300 is unloaded or loaded from or to the frame support plates 54 by the frame rails 55. Further, the material frame device 5 further comprises a second positioning mechanism, the second positioning mechanism comprises two third positioning plates 56 arranged on the material frame supporting plate 54, the three third positioning plates 56 are arranged at intervals along the pushing direction of the layered bar material 200, the material frame 300 is arranged between the two third positioning plates 56, so that the deviation along the pushing direction cannot occur, and the bar material 200 pushed by the pushing plate 421 can be arranged in the material frame 300. Further, referring to fig. 18 and 19, the frame device 5 further includes a third positioning mechanism 57, the third positioning mechanism 57 includes a third driving mechanism 571 disposed below the frame supporting plate 54 and a fourth positioning plate 572 disposed at an output end of the third driving mechanism 571, a through groove 541 penetrating along a third direction is formed in the center of the frame supporting plate 54, one of the fourth positioning plate 572 and the bottom plate of the frame 300 is provided with a positioning hole, the other is provided with a positioning element, a main body of the third driving mechanism 571 is fixed relative to the frame supporting plate 54, after the frame 300 is pushed onto the frame supporting plate 54, the third driving mechanism 571 drives the fourth positioning plate 572 to approach the frame 300, so that the positioning element is inserted into the positioning hole, thereby positioning the frame 300 is realized, and the frame 300 is ensured not to be deviated. Optionally, the number of the positioning holes and the positioning members may be two, and the positioning holes and the positioning members are arranged in a diagonal direction of the rectangular structure, so as to sufficiently ensure the positioning of the material frame 300 on the horizontal plane. Optionally, the positioning member is a positioning pin.

When the pushing mechanism 42 pushes the bar material 200, in order to ensure that the bar material 200 is tightly arranged in the material frame 300 without loosing, after the bar material is pushed into the material frame 300, two ends of the layered bar material 200 in the width direction are abutted with the inner wall of the material frame 300 as much as possible, that is, a small fit clearance is maintained. It will be appreciated that for the two adjacent layers of the laminated bars 200 with different total widths, the layer of the bars 200 with larger width dimension is kept in contact with the inner wall of the material frame 300, so that the laminated bars 200 with smaller width dimension are clamped in the middle, and the overall stability is still ensured. In this embodiment, for the bar stock 200 having a regular hexagonal prism structure, the number of the layered bar stock 200 at the bottom layer is 72, the number of the layered bar stock 200 at the penultimate layer is 71, the number of the layered bar stock 200 at the penultimate layer is 72, and so on … …, wherein the 72 layered bar stock 200 can abut against the inner wall of the material frame 300, so as to ensure the stability of the whole bar stock 200. Further, it is required that the electric control device should adequately consider the size of the inner space of the material frame 300 and reasonably set the preset range of the total width of each layer of bar material 200 when calculating.

Further, taking the stack of bars 200 of regular hexagonal prism structure as an example, when 72 and 71 bars 200 need to be pushed, the 72 bars 200 can abut against the side wall of the material frame 300, but the 71 bars 200 need the layer of bars 200 to be located at the middle position of the whole material frame 300, that is, the layer of bars 200 has the same gap with the two opposite side walls of the material frame 300. However, the position of the material frame 300 is fixed, the clip loading mechanism 41 sequentially completes the arrangement of the bars 200, the last bars 200 of the layered bars 200 with different widths are all located at the entrance of the clip 410, so that although the total widths of the bars 200 with different total numbers are different, the last bars 200 of the layered bars 200 are all abutted against the side wall of the material frame 300 during pushing, and thus the layer of bars 200 with smaller total width cannot be located in the middle of the material frame 300, and regular stacking cannot be achieved, so that the position of the whole clip device 4 in the second direction needs to be changed, so that the push plate 421 can push the layer of bars 200 to the middle of the material frame 300, and ensure the bars 200 are attached to the upper and lower layers of bars 200. Therefore, referring to fig. 14, a thirteenth driving module 45 is further disposed between the first module fixing plate 43 and the frame 100, and the thirteenth driving module 45 is used for driving the first module fixing plate 43 and the entire clip device 4 to move along the second direction, so as to change the position of the layered bar material 200 relative to the material frame 300. It will be appreciated that the above process can be omitted when bar 200 is free of the problem of inconsistent widths of adjacent layers.

Although the position of the material frame 300 is located and limited, in order to ensure that the layered bar material 200 is pushed into the material frame 300 accurately and abuts against the inner wall of the material frame 300, the side of the bar material 200 arranged at the last time is flush with the inner wall of the material frame 300, i.e. the coordinate in the second direction remains the same, therefore, the thirteenth driving module 45 is arranged to solve the problem that the layered bar material 200 cannot be pushed into the material frame 300 accurately. In order to accurately know the specific moving distance of the layered bar material 200, a laser head 58 is arranged on the frame support plate 54, detects the coordinate of the outer wall of the frame 300 pushed into the frame support plate 54 by the principle of light reflection, and obtains the first coordinate of the inner wall of the frame 300 by the thickness (fixed value) of the frame 300, and a first laser displacement sensor 313 can measure the second coordinate of the side part of the last bar material 200 of the layered bar material 200 in the clip 410, and obtains the moving amount of the clip device 4 in the second direction by comparing the two coordinates, so that the side part of the last bar material 200 can just abut against the inner wall of the frame 300 when the layered bar material 200 is pushed in.
