Description

Technical Field

[0001] The invention relates to the technical field of roll material threading and pulling shafts, in particular to an automatic threading and pulling shaft system for roll materials. Background Art

[0002] In the production process of a printing and packaging factory, roll materials (such as roll plastic film and roll paper) must undergo multiple processing steps, including printing, laminating, curing, and slitting. After the laminating process is completed and before entering the intelligent curing chamber, the roll material must be threaded through a material shaft for curing. Once the curing process is complete and the roll material is removed from the curing chamber, the material shaft must be removed to allow it to enter the next production process. Furthermore, other steps in the production process often require the operation of threading and removing material shafts.

[0003] Currently, the industry's most common method for threading and unthreading webs is manual loading and threading. This traditional operation not only results in high labor intensity and low efficiency, but also leads to high labor costs, which, to a certain extent, restricts the improvement of production efficiency.

[0053] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0054] like Figure 1-2 As shown, an embodiment of the present invention provides an automatic threading and pulling shaft system for roll materials, the automatic threading and pulling shaft system includes a material shaft loading device 1, a material shaft storage and circulation device 2, a material shaft threading device 3 and a material roll support device 4 arranged adjacent to each other in sequence, the material shaft loading device 1 is used to drive the material shaft a to transfer from the lower part of the first side to the loading position of the material shaft storage and circulation device 2 at the top of the second side.

[0055] The material shaft storage and circulation device 2 is used to store the material shaft a transferred by the material shaft loading device 1 and the material shaft a pulled out by the material shaft pulling device 3, and / or to provide the material shaft a to the material shaft pulling device 3 when the material shaft is being pulled out. The material shaft pulling device 3 is used to clamp and drive the material shaft a provided by the material shaft storage and circulation device 2 to pass it to the material roll b in the material roll support device 4, and / or to clamp and pull out the material shaft a of the material roll b in the material roll support device 4, and the material roll support device 4 is used to support the material roll b. The material shaft storage and circulation device 2 can not only store the new material shaft a transferred by the loading device, but also recycle the old material shaft a pulled out by the pulling device, and provide the material shaft a to the threading process as needed, forming a closed-loop management of the material shaft a. This orderly storage and circulation mode avoids the confusion and loss caused by the random stacking of material shafts a, improves the turnover efficiency and reuse rate of material shafts a, and reduces the cost of production materials.

[0056] The coordinated operation of the spool loading device 1, the spool storage and circulation device 2, the spool threading and extraction device 3, and the coil support device 4 automates the entire process of loading, storing, threading, and extracting spool a, as well as supporting coil b. This eliminates the need for workers to manually handle spool a and repeatedly thread and extract it, freeing them from heavy physical labor and significantly reducing labor intensity.

[0057] It should be noted that the automatic threading and pulling shaft system for roll materials in this embodiment can be flexibly adapted to various working conditions according to actual needs: it can be used only for the pulling shaft operation of roll b, or only for the threading shaft operation of roll b, and can also be suitable for working conditions where pulling and threading shafts are performed alternately.

[0058] like Figure 3 As shown, the material shaft feeding device 1 includes a first frame 11, a first lifting mechanism 12 and a material shaft placing mechanism 13, wherein the material shaft placing mechanism 13 is located at the lower part of the first side of the first frame 11, the material shaft storage and circulation device 2 is located at the second side of the first frame 11, and the first lifting mechanism 12 is arranged on the first frame 11. Figure 5 As shown, the right side is the first side of the first frame 11 , and the left side is the second side of the first frame 11 .

[0059] like Figure 4 As shown, the first lifting mechanism 12 includes a first driving member 121, two chain transmission members 122 and a plurality of movable plates 123. The two chain transmission members 122 are arranged at intervals on the first frame 11, and the transmission path of the chain transmission member 122 includes an ascending vertical section located on the first side of the first frame 11, a descending vertical section located on the second side of the first frame 11, and a top horizontal transition section connecting the ascending vertical section and the descending vertical section.

[0060] Multiple moving plates 123 are arranged at intervals on the chain transmission member 122. The moving plates 123 on the two chain transmission members 122 correspond to each other horizontally. The transmission path of the chain transmission member 122 is an upward vertical section, a top horizontal transition section and a downward vertical section, so that the material shaft a can achieve vertical ascent, flip transfer and vertical downward coherent movement, ensuring the smoothness and stability of the material shaft a transmission and avoiding the problem of the material shaft a falling or getting stuck during the transmission process. Figure 12 As shown, the first driving member 121 drives the two chain transmission members 122 to move synchronously, so that a pair of horizontally corresponding movable plates 123 on the two chain transmission members 122 ascend in the ascending vertical section to the position of the material shaft placing mechanism 13 to support the material shaft a on the material shaft placing mechanism 13, and drive the material shaft a to rise vertically along the ascending vertical section. In the process of the material shaft a flipping through the top horizontal transition section to the descending vertical section, the material shaft a is transferred to the loading position of the material shaft storage and circulation device 2 at the top of the second side of the first frame 11.

[0061] Among them, the material shaft a is used for a roll of plastic film or roll of paper, that is, the material roll b is a roll of plastic film or roll of paper, the material shaft a is a rotating body structure, the material shaft a includes a middle section and overlapping sections arranged on both sides of the middle section, and the movable plate 123 supports the middle section of the material shaft a. When it is transferred to the loading position of the material shaft storage and circulation device 2 at the top of the second side of the first frame 11, the loading position at the top of the second side supports the overlapping sections on both sides of the material shaft a. Of course, in actual application, the loading position of the material shaft storage and circulation device 2 at the top of the second side does not interfere with the downward movement of the movable plate 123.

[0062] The material shaft loading device 1 realizes the automated operation of material shaft a loading through the cooperation of the first frame 11, the first lifting mechanism 12 and the material shaft placement mechanism 13. The two chain transmission members 122 of the first lifting mechanism 12 move synchronously, driving the movable plate 123 to move on a specific path, which can automatically support the material shaft a on the material shaft placement mechanism 13 and transport it from the lower part of the first side of the first frame 11 to the loading point at the top of the second side. No manual loading is required, which greatly reduces the labor intensity of workers. Compared with manual loading, the automated transmission process is continuous and stable, reducing the tedious steps and time consumption of manual operation, significantly improving the efficiency of loading operations, and meeting the efficient demand for material shaft a loading in scenarios such as printing and packaging factories.

[0063] like Figure 3 As shown, the chain transmission member 122 includes a transmission chain 1221, a driving sprocket 1222 and a passive sprocket 1223. The transmission chain 1221 is engaged between the driving sprocket 1222 and the passive sprocket 1223, and the movable plate 123 is arranged on the transmission chain 1221. The fixed end of the first driving member 121 is arranged on the first frame 11, and the driving end of the first driving member 121 is connected to the long shaft. The driving sprockets 1222 of the two chain transmission members 122 are fixedly mounted on the long shaft, and the passive sprocket 1223 is rotatably arranged on the first frame 11. After the first driving member 121 is started, the two driving sprockets 1222 are driven to rotate synchronously through the long shaft, thereby driving the transmission chain 1221 to move, thereby realizing the synchronous operation of the two chain transmission members 122. Among them, as Figure 5 As shown, the transmission chain 221 rotates counterclockwise, the right side is the upward vertical section located on the first side of the first frame 11, the left side is the downward vertical section located on the second side of the first frame 11, and the top is the top horizontal transition section connecting the upward vertical section and the downward vertical section.

[0064] like Figure 5As shown, one end of the movable plate 123 is fixedly connected to a link of the transmission chain 1221. The connection method can be welding or bolting to ensure the connection strength. The movable plate 123 has an L-shaped structure. The supporting portion of the movable plate 123 is used to support the middle section of the material shaft a. When the transmission chain 1221 drives the movable plate 123 to be in the upward vertical section, the supporting portion of the movable plate 123 is perpendicular to the moving direction of the transmission chain 1221 and tilted inward at a certain angle. This allows the material shaft a to be stably placed on the supporting portion of the movable plate 123, preventing the material shaft a from sliding during the upward process and improving the support stability.

[0065] like Figure 4 As shown, the first lifting mechanism 12 also includes a tensioning unit 125. A driven sprocket 1223 is mounted on the tensioning unit 125 via a rotating shaft. The tensioning unit 125 is adjustably mounted on the first frame 11. The tensioning unit 125 can be adjusted using a bolt mechanism. By adjusting the mounting position of the tensioning unit 125 on the first frame 11, the position of the driven sprocket 1223 is changed, thereby adjusting the tension of the transmission chain 1221. When the transmission chain 1221 becomes slack, the tensioning unit 125 is adjusted to move the driven sprocket 1223 away from the driving sprocket 1222, thereby tightening the transmission chain 1221 and ensuring transmission reliability.

[0066] like Figure 6 As shown, the material shaft placement mechanism 13 includes a movable frame 131 and two support rods 132. The two support rods 132 are arranged in parallel and spaced apart on the movable frame 131. The support rods 132 are inclined toward the direction close to the first frame 11. The inclination angle can be set according to actual needs, generally 3°-5°. The two support rods 132 are used to support the overlapping sections on both sides of the material shaft a. The spacing between the two chain transmission members 122 is smaller than the spacing between the two support rods 132, so that the movable plate 123 can smoothly pass between the two support rods 132 during movement, thereby supporting the middle section of the material shaft a located on the support rods 132.

[0067] like Figure 6 and Figure 7 As shown, the bottom of the mobile frame 131 is provided with four moving wheels 133 and a plurality of first rolling wheels 134. The four moving wheels 133 are provided at the four corners of the bottom of the mobile frame 131 for walking on the ground, so as to facilitate the movement of the mobile frame 131 between different areas. Figure 5 As shown, the first frame 11 includes a first mounting frame 111 and a second mounting frame 112 connected to each other. The first mounting frame 111 extends longitudinally and the second mounting frame 112 extends horizontally. The first lifting mechanism 12 is arranged on the first mounting frame 111. The second mounting frame 112 is provided with a guide rail for the first rolling wheel 134 to slide. When the mobile frame 131 needs to work in conjunction with the first frame 11, the first rolling wheel 134 of the mobile frame 131 slides along the guide rail to the specified position.

[0068] like Figure 8-10 As shown, the material shaft feeding device 1 also includes a locking mechanism 14, as shown in FIG. Figure 9 As shown, the locking mechanism 14 includes a first telescopic member 141 and a locking plate 142. The first telescopic member 141 is provided on the second mounting frame 112. The telescopic end of the first telescopic member 141 is connected to the locking plate 142. The locking plate 142 can be moved horizontally to engage with the movable frame 131 to limit the displacement of the movable frame 131. The first telescopic member 141 can be a pneumatic cylinder or a hydraulic cylinder. When the movable frame 131 is placed on the second mounting frame 112, part of the movable frame 131 abuts against the locking plate 142. The first telescopic member 141 retracts and drives the movable frame 131 to move through the locking plate 142, so that the movable frame 131 abuts against the second mounting frame 112 and fixes the movable frame 131. When the movable frame 131 needs to be moved, the first telescopic member 141 extends to release the lock on the movable frame 131. Figure 10 , which is a structural diagram of the movable frame 131 being locked with the locking plate 142 through the second rolling wheel 135 .

[0069] like Figure 8 and Figure 11 As shown, the second mounting frame 112 is equipped with two guide plates 113 and two abutment plates 114. The two abutment plates 114 are arranged in parallel and spaced apart to limit the movement direction of the movable frame 131. The two guide plates 113 are arranged on either side of the moving path of the movable frame 131 to guide the movement direction. The ends of the guide plates 113 away from the abutment plates 114 are tilted outward to form a bell-shaped shape. This guide function serves as a guide when the movable frame 131 approaches the second mounting frame 112, allowing the movable frame 131 to accurately enter between the two guide plates 113.

[0070] like Figure 9 and Figure 10 As shown, a second rolling wheel 135 is provided on the movable frame 131. The second rolling wheel 135 is provided on a side of the movable frame 131 close to the second mounting frame 112. The locking plate 142 cooperates with the second rolling wheel 135. The locking plate 142 drives the second rolling wheel 135 to move along the extension direction of the movable frame 131. The rolling surface of the second rolling wheel 135 contacts the locking plate 142. When the locking mechanism 14 drives the movable frame 131 close to the first frame 11, due to the action of the guide plate 113, the movable frame 131 will move slightly left and right in the process of approaching the first frame 11. The second rolling wheel 135 converts the sliding friction between the locking plate 142 and the movable frame 131 into rolling friction, thereby reducing frictional resistance, making the locking and unlocking process smoother, and also reducing wear on components.

[0071] like Figure 3 and Figure 6As shown, the material shaft loading device 1 also includes a first transport vehicle 15, which is an AGV automatic guided transport vehicle. The first transport vehicle 15 is arranged below the material shaft placement mechanism 13. The first transport vehicle 15 carries the material shaft placement mechanism 13 to move and places the material shaft placement mechanism 13 on the second mounting frame 112. The first transport vehicle 15 can be hydraulically lifted. When the material shaft placement mechanism 13 needs to be transferred, the first transport vehicle 15 is driven below the material shaft placement mechanism 13, the carrying platform of the first transport vehicle 15 is raised to lift the material shaft placement mechanism 13, and then the first transport vehicle 15 is moved to the designated position, and then the carrying platform is lowered to place the material shaft placement mechanism 13 on the second mounting frame 112. It should be noted that the AGV automatic guided transport vehicle belongs to the existing technology, and its specific structure will not be repeated here.

[0072] like Figure 13 As shown, the material shaft storage and circulation device 2 includes a second frame 21, a first material moving mechanism 25, a second material moving mechanism 26, and a receiving mechanism 27. The first material moving mechanism 25, the second material moving mechanism 26, and the receiving mechanism 27 are arranged on the second frame 21. Among them, the second frame 21 is provided with a first storage bin 22, a second storage bin 23, and a third storage bin 24, which are staggered from bottom to top. By setting up three layers of storage bins, the storage capacity of material shafts a is significantly increased compared to the traditional clip-type material shaft a bin, solving the problem of insufficient capacity when the material shafts are centrally threaded or pulled out. The low side of the third storage bin 24 is tilted toward the high side of the second storage bin 23, and the low side of the second storage bin 23 is tilted toward the high side of the first storage bin 22, so that the material shafts a can automatically roll to the receiving position of the material moving mechanism with the help of gravity, reducing manual intervention and improving circulation efficiency.

[0073] The lower side of the first storage bin 22 is tilted toward the shaft threading device 3 to provide the shaft a for threading to the shaft threading device 3. It should be noted that in this embodiment, the first storage bin 22, the second storage bin 23, and the third storage bin 24 are all tilted. For ease of understanding, the higher side of the storage bin is the high side, and the lower side is the low side.

[0074] The first material transfer mechanism 25 is located at the lower side of the third storage bin 24 and is used to receive the material shaft a at the end of the third storage bin 24 and drive the material shaft a to move vertically and place it in the second storage bin 23. The receiving mechanism 27 is located at the upper side of the second storage bin 23 and is used to receive the material shaft a pulled out by the material shaft pulling device 3 above. The second material transfer mechanism 26 is located at the lower side of the second storage bin 23 and is used to receive the material shaft a at the end of the second storage bin 23 and drive the material shaft a to move vertically and place it in the first storage bin 22. Among them, the third storage bin 24 is used to store the material shaft a transferred by the material shaft loading device 1, wherein the high side of the third storage bin 24 is the loading place of the material shaft storage and circulation device 2. Part of the material shaft a of the second storage bin 23 comes from the material shaft a circulated by the third storage bin 24, and the other part comes from the material shaft a pulled out by the material shaft pulling device 3 in the second storage bin 23 through the receiving mechanism 27. Finally, the second storage bin 23 is transferred to the first storage bin 22 through the second material transfer mechanism 26, and the low side of the first storage bin 22 provides the material shaft a for the material shaft pulling device 3 during the pulling operation. The first material transfer mechanism 25 transfers the material shaft a from the third storage bin 24 to the second storage bin 23, and the second material transfer mechanism 26 transfers the material shaft a from the second storage bin 23 to the first storage bin 22. Combined with the receiving mechanism 27 to receive the material shaft a pulled out by the material shaft pulling device 3, a closed loop of "storage-transfer-re-storage" is formed, realizing the full process automation of the pulling and pulling operations.

[0075] like Figure 13 and Figure 16 As shown, the receiving mechanism 27 comprises a telescopic drive unit 271, a second long shaft 272, and a plurality of rotating plates 273 mounted on and fixed to the second long shaft 272. The rotating plates 273 are spaced apart on the second long shaft 272 and support the middle section of the material shaft a. The second long shaft 272 is located at the upper end of the second storage bin 23 and rotates relative to the end of the second storage bin 23 via mounting plates 274. Two mounting plates 274 are respectively fixed to the outer portion of the upper side of the second storage bin 23. The second long shaft 272 passes through the mounting plates 274 and is rotatably connected to the mounting plates 274. The telescopic drive unit 271 is mounted on the second frame 21. It rotates the second long shaft 272, which in turn rotates the rotating plates 273 to receive the material shaft a pulled from the upper material shaft extraction device 3 and into the second storage bin 23. This rotational action precisely receives the material shaft a pulled from the upper roll b, preventing the material shaft a from drifting or jamming due to free fall. The rotating plate 273 can be stored close to the bottom of the storage bin when not in operation, reducing the space occupied by surrounding equipment and avoiding interference with other mechanisms when they are working. Figure 17As shown, in order to allow the received material shaft a to enter the second storage bin 23 smoothly, the receiving mechanism 27 also includes two guide plates 275. The two guide plates 275 are arranged opposite to each other and are located at the ends on the high side of the second storage bin 23 to form an open design, forming a physical barrier in the process of the material shaft a entering the second storage bin 23 to prevent the material shaft a from getting stuck due to angle deviation.

[0076] like Figure 16 As shown, the telescopic drive unit 271 includes two second telescopic members 2711 and two hinged plates 2712. The two second telescopic members 2711 are respectively arranged at both ends of the second long axis 272. The fixed end of the second telescopic member 2711 is connected to the second frame 21. One end of the hinged plate 2712 is hinged to the telescopic end of the second telescopic member 2711, and the other end of the hinged plate 2712 is connected to the second long axis 272. The two second telescopic members 2711 are respectively connected to the second long axis 272 via the hinged plates 2712. The receiving angle of the rotating plate 273 can be adjusted according to the different diameters of the material shaft a to ensure stable receiving under different material shaft diameters a.

[0077] like Figure 18 and Figure 19 As shown, the first material moving mechanism 25 and the second material moving mechanism 26 both include a linear drive member A1 and a transfer frame A2. The transfer frame A2 is used to receive the material shaft a. The fixed end of the linear drive member A1 is connected to the second frame 21.

[0078] like Figure 13 and Figure 18 As shown, the telescopic end of the linear drive member A1 of the first material moving mechanism 25 drives the first transfer frame A2 of the first material moving mechanism 25 to move vertically between the lower end of the third storage bin 24 and the upper end of the second storage bin 23 to receive the material shaft a at the end of the third storage bin 24 and drive the material shaft a to move vertically and place it in the second storage bin 23. Figure 13 and Figure 19 As shown, the telescopic end of the linear drive member A1 of the second material moving mechanism 26 drives the transfer rack A2 to move in the vertical direction between the lower side end of the second storage bin 23 and the high side of the first storage bin 22 to receive the material shaft a at the end of the second storage bin 23 and drive the material shaft a to move vertically and be placed in the first storage bin 22.

[0079] like Figure 14 and Figure 15 As shown, the first material moving mechanism 25 also includes a first proximity switch 251 arranged on the second frame 21. The first proximity switch 251 is arranged at the lower side end of the third storage bin 24 and is used to detect whether there is a material shaft a on the transfer frame A2 of the first material moving mechanism 25.

[0080] like Figure 18 and Figure 19As shown, the transfer frame A2 includes a first connecting rod A21 and two transfer plates A22. The first connecting rod A21 is horizontally oriented and extends along the width direction of the second frame body 21, and the bottom of the first connecting rod A21 is connected to the telescopic end of the linear drive member A1. The two transfer plates A22 are respectively arranged on both sides of the first connecting rod A21. One side of the transfer plate A22 is provided with a stop portion A221 and a groove A222 in the vertical direction. The stop portion A221 is used to stop the material shaft a, and the groove A222 is used to receive the middle section of the material shaft a.

[0081] In this embodiment, the stopper A221 on the transfer plate A22 provides lateral limitation during the transfer of the material shaft a, preventing the remaining material shafts a in the storage bin from falling. The groove A222 matches the shape of the received material shaft a, doubly ensuring the stability of the material shaft a during the transfer process. In this embodiment, the bottom surface of the groove A222 is an inclined surface. When the material shaft a rolls into the groove A222 and moves downward, the material shaft a will not roll out of the groove A222. The size of the groove A222 can be standardized according to the diameter of the material shaft a, adapting to various specifications of the material shaft a and improving the versatility of the device. It should be noted that in this embodiment, only the position of the groove A222 of the transfer plate A22 is different in the first material transfer mechanism 25 and the second material transfer mechanism 26.

[0082] like Figure 18 and Figure 19 As shown, the first material moving mechanism 25 and the second material moving mechanism 26 also include two groups of first guide assemblies A3 arranged at intervals. Each group of first guide assemblies A3 includes a first guide rail A31, a first guide slider A32 and two first limit plates A33. The first guide rail A31 is vertically oriented and arranged on the second frame 21. The first guide slider A32 is arranged on the first connecting rod A21 and is slidably connected to the first guide rail A31. When the linear drive member A1 drives the transfer frame A2 to move in the vertical direction, the first guide slider A32 slides along the first guide rail A31. The cooperation between the first guide rail A31 and the first guide slider A32 can ensure that the transfer frame A2 has no lateral deviation during the vertical movement. The two first limit plates A33 are respectively arranged at both ends of the first guide rail A31 to limit the first guide slider A32, and then used to limit the travel of the transfer frame A2, ensuring that the linear drive member A1 has an up and down travel during operation and that the material shaft a rolls smoothly into or out of the slot.

[0083] like Figure 13As shown, to prevent the transfer plate A22 in the first and second material moving mechanisms 25 and 26 from interfering with the storage bins during operation and to facilitate the material shaft a from rolling out of the slot, the first, second, and third storage bins 22, 23, and 24 are each constructed with two spaced support rods extending along the length of the second frame 21. The overlapping sections of the material shaft a overlap the supporting rods on both sides of the storage bins. The transfer rack A2 in the first and second material moving mechanisms 25 and 26 is located between the two support rods, and the groove A222 on the transfer rack A2 cooperates with the middle section of the material shaft a. When the linear drive member A1 drives the transfer rack A2 downward to transfer the material shaft a to the next storage bin, the overlapping sections at both ends of the material shaft a overlap the two support rods 132 of the next storage bin. When the linear drive member A1 further descends, the material shaft a disengages from the groove A222 of the transfer plate A22, and the material shaft a then enters the storage bin and rolls along the tilted direction.

[0084] like Figure 13 As shown, the support rods 132 of the second and third storage bins 23, 24 are provided with first shielding plates 28 along their lengths. The two first shielding plates 28 are arranged opposite each other and form an open design. They form a physical barrier when the material shaft a enters the second and third storage bins 23, 24, preventing the material shaft a from getting stuck due to angular deviation.

[0085] like Figure 20 and Figure 21 As shown, the material shaft threading device 3 includes a third frame 31, a second lifting mechanism 32 and a clamping and transverse moving mechanism 33. The second lifting mechanism 32 and the clamping and transverse moving mechanism 33 are both arranged on the third frame 31, wherein the material roll b is located on the outside of the third frame 31 and opposite to the end of the clamping and transverse moving mechanism 33.

[0086] like Figure 22 As shown, the second lifting mechanism 32 includes a second driving member 321 and a support frame 322, the support frame 322 is used to support the material shaft a, the fixed end of the second driving member 321 is connected to the third frame 31, wherein the second driving member 321 is a double-stroke cylinder, as shown Figure 26 and Figure 27 As shown, the telescopic end of the second driving member 321 drives the support frame 322 to move between the first position, the second position and the third position in the vertical direction, wherein the first position, the second position and the third position are arranged in sequence from bottom to top in the vertical direction, and the second lifting mechanism 32 can drive the support frame 322 to move in the vertical direction for feeding when the material roll b in the material roll support device 4 is threaded through the shaft, that is, sending the material shaft a from the first position to the third position, and can also be used for receiving when the material roll b in the material roll support device 4 is pulled out of the shaft, that is, lowering the material shaft a from the third position to the second position so that the subsequent material shaft storage and circulation device 2's receiving mechanism 27 can receive the material shaft a and facilitate the subsequent storage of the material shaft a.

[0087] The clamping and transverse movement mechanism 33 includes a linear motion assembly 331 and a clamping claw assembly 332. The clamping claw assembly 332 is used to clamp the material shaft a. The linear motion assembly 331 is mounted on the third frame 31 and is located above the support frame 322. The linear motion assembly 331 extends along the width of the third frame 31. The movable end of the linear motion assembly 331 drives the clamping claw assembly 332 to move horizontally and linearly along the width of the third frame 31. This allows the material shaft a to be removed from the material roll b in the material roll support device 4, which is mounted at the end of the linear motion assembly 331, and placed on the support frame 322, or the material shaft a provided by the material roll feeding device 3 to the support frame 322 is inserted into the material roll b in the material roll support device 4. One end of the linear motion assembly 331 extends beyond the third frame 31, allowing the clamping claw assembly 332 to drive the material shaft thereon to fully enter the material roll b in the material roll support device 4.

[0088] The clamping and transverse movement mechanism 33 can drive the clamping claw assembly 332 to move horizontally through the linear movement component 331 to complete the shaft threading or pulling action, effectively replacing manual operation, greatly reducing the labor intensity of workers, significantly improving the efficiency of shaft threading and pulling operations, and simultaneously reducing labor costs, which is conducive to improving production efficiency. The material shaft threading and pulling device 3 of this embodiment realizes the mechanized operation of the material shaft a threading and pulling operation through the coordinated cooperation of the third frame 31, the second lifting mechanism 32 and the clamping and transverse movement mechanism 33.

[0089] like Figure 22 As shown, the support frame 322 includes a second connecting rod 3221 and two lifting plates 3222. The second connecting rod 3221 is horizontally oriented and extends along the width of the third frame 31. The bottom of the second connecting rod 3221 is connected to the telescopic end of the second driving member 321. The two lifting plates 3222 are respectively arranged on either side of the second connecting rod 3221. The top ends of the lifting plates 3222 are recessed with arcuate grooves, the shape of which is adapted to the outer surface of the material shaft a. The support frame 322 adopts a structure in which the second connecting rod 3221 connects the two lifting plates 3222, and the top ends of the lifting plates 3222 are recessed with arcuate grooves adapted to the outer surface of the material shaft a. The lifting plates 3222 are used to receive the material shaft a provided by the material shaft insertion and extraction device 3 or the material shaft a extracted by the clamping and traversing mechanism 33. The arcuate grooves can provide stable support and positioning for the material shaft a, preventing the material shaft a from shaking or shifting during the support process, and ensuring the position accuracy of the material shaft a when clamped by the clamping assembly. To further prevent the shaft a from falling out when the support frame 322 receives the shaft a in the first position, a second shielding plate 325 is provided on one side of the third frame 31. The second shielding plate 325 is located at a position opposite to the support frame 322 when it is in the first position. Furthermore, to prevent the shaft a from falling out of the lower side of the first storage bin 22 in the shaft storage and circulation device 2 when the second driving member 321 drives the support frame 322 to move, a lifting plate 3222 of the support frame 322 forms a stopper on the side near the shaft loading device 3.

[0090] like Figure 22 As shown, the second lifting mechanism 32 also includes a second proximity switch 324 provided on the third frame 31. The second proximity switch 324 is provided at a position opposite to the support frame 322 when it is in the first position. It is used to detect whether the material shaft a has entered the support frame 322, thereby facilitating the automated linkage control of the threading and pulling operations, improving the intelligence of the device, reducing the need for manual monitoring, and further improving the level of automation in production. It should be noted that the automated control logic and related procedures involved in this embodiment are not within the scope of protection of this patent.

[0091] When the material roll b is threaded through the material shaft a, the second driving member 321 drives the support frame 322 to the first position, and the material shaft a enters the arc groove of the lifting plate 3222 of the support frame 322, wherein the second proximity switch 324 is used to detect whether the material shaft a enters the lifting plate 3222 on the support frame 322, and the second driving member 321 drives the support frame 322 to move vertically to the third position, i.e., the threading preparation position, to facilitate the clamping of the material shaft a by the clamping claw assembly 332.

[0092] When the material shaft a is pulled out from the material roll b, the second driving member 321 drives the support frame 322 to the third position to prepare to receive the material shaft a pulled out by the clamping claw assembly 332. After the support frame 322 receives the material shaft a, the second driving member 321 drives the material shaft a to drop to the second position so that the subsequent material shaft storage and circulation device 2 can receive the material shaft a and facilitate the subsequent storage of the material shaft a.

[0093] like Figure 22 As shown, the second lifting mechanism 32 further includes two sets of spaced-apart second guide assemblies 323. Each set of second guide assemblies 323 includes a second guide rail 3231 and a second guide slider 3232. The second guide rail 3231 is vertically oriented and arranged on the third frame 31. The slider is arranged on the second connecting rod 3221 and is slidably connected to the second guide rail 3231. When the second driving member 321 drives the support frame 322 to move in the vertical direction, the second guide slider 3232 slides along the second guide rail 3231. When the second driving member 321 drives the support frame 322 to move vertically, the second guide assembly 323 can accurately guide the movement direction of the support frame 322, effectively limiting the deviation of the support frame 322, making the lifting and lowering movement of the support frame 322 smoother and more stable, thereby improving the stability of the operation of the second lifting mechanism 32.

[0094] In this embodiment, the second guide assembly 323 further includes a second limiting plate 3233, which is disposed at the top end of the second guide rail 3231 to limit the position of the second guide slider 3232. Specifically, the second limiting plate 3233 limits the travel of the second guide slider 3232, preventing the second guide slider 3232 from excessive movement and disengaging from the second guide rail 3231. When the second limiting plate 3233 limits the position of the second guide slider 3232, the second driving member 321 drives the support frame 322 to the third position, ensuring that when the support frame 322 is in the third position, the material axis a is exactly at the center of the clamping jaw assembly 332.

[0095] like Figure 23 and Figure 24 As shown, the clamping assembly 332 includes an opening and closing drive unit 3321 and two oppositely disposed clamping units 3322. The opening and closing drive unit 3321 is a guide rail slider structure. The guide rail of the opening and closing drive unit 3321 extends along the length direction of the third frame 31, that is, perpendicular to the extension direction of the linear motion assembly 331. The moving end of the linear motion assembly 331 is connected to the guide rail in the opening and closing drive unit 3321. The two moving ends on the opening and closing drive unit 3321 are respectively connected to the two clamping units 3322 and drive the two clamping units 3322 to move toward or away from each other to clamp or release the material shaft a. In this embodiment, the clamping assembly 332 uses a guide rail slider structure to drive the two clamping units 3322 to move toward or away from each other, which can achieve stable clamping and release of the material shaft a. The opening and closing action of the clamping units 3322 is highly controllable and can adapt to the clamping requirements of material shafts a of different diameters and specifications, thereby improving the adaptability of the device to different material shafts a.

[0096] like Figure 23 As shown, the two clamping jaw units 3322 have identical structures and are arranged in a mirror-like manner. Each clamping jaw unit 3322 includes a connecting plate 33221 and two clamping jaw bodies 33222. The two connecting plates 33221 are respectively connected to the two sliders of the opening and closing drive unit 3321. The two clamping jaw bodies 33222 are connected to the bottom end of the connecting plate 33221 and are spaced apart. The two clamping jaw bodies 33222 in the two clamping jaw units 3322 are arranged in a one-to-one correspondence. The provision of the dual clamping jaw bodies 33222 increases the contact area with the material shaft a, making the clamping jaws more stable on the material shaft a, dispersing the clamping force, reducing the risk of damage to the material shaft a due to localized excessive force, and further improving the reliability of the clamping operation. Of course, to further increase friction and prevent the material shaft a from falling, anti-slip pads are provided on the contact surface of the clamping jaw bodies 33222.

[0097] like Figure 24As shown, the clamping jaw assembly 332 also includes a synchronization unit 3323, which includes a gear 33231 and two racks 33232. The two racks 33232 are respectively connected to the connecting plates 33221 of the two clamping jaw units 3322. The two racks 33232 are meshed with the gear 33231. The gear 33231 is connected to the opening and closing drive unit 3321 via a connecting shaft 33233. The gear 33231 rotates along the axis of the connecting shaft 33233. When the opening and closing drive unit 3321 drives the clamping jaw unit 3322 to move, the synchronization unit 3323 ensures that the movement of the two clamping jaw units 3322 remains synchronized, avoiding offset clamping of the material axis a or uneven force due to asynchronous movement of the clamping jaw units 3322. This ensures the coordination and consistency of the opening and closing movements of the clamping jaw assembly 3322 and improves clamping accuracy.

[0098] like Figure 21 As shown, in actual application, the clamping jaw assembly 32 clamps one side of the material shaft a. Since the material shaft a is long, in order to prevent the clamping jaw assembly from tilting one side of the material shaft a when driving the material shaft a to move, so that it cannot accurately enter the material roll b. The material shaft threading and pulling device 3 also includes a guide wheel mechanism 34. The guide wheel mechanism 34 is arranged on the third frame 31 and is located below the linear moving assembly 331 on the side close to the material roll b. The guide wheel mechanism 34 is used to provide rolling support for the material shaft a when the clamping jaw assembly 332 clamps the material shaft a and moves. During the process of the clamping jaw assembly 332 clamping the material shaft a and moving, the guide wheel mechanism 34 can provide rolling support for the material shaft a, share the weight of the material shaft a, reduce the stress burden of the clamping jaw assembly 332, and at the same time prevent the material shaft a from sagging due to gravity during movement, which affects the threading and pulling accuracy, making the movement of the material shaft a more stable.

[0099] like Figure 25As shown, the guide wheel mechanism 34 includes a third telescopic member 341, a connecting frame 342 and a V-shaped roller 343. The V-shaped roller 343 is horizontally oriented and rotatably connected to the connecting frame 342. The telescopic end of the third telescopic member 341 is connected to the V-shaped roller 343 through the connecting frame 342 to drive the V-shaped roller 343 to rise and fall, wherein the V-shaped roller 343 is used to support the material shaft a. The V-shaped roller 343 can better adapt to the shape of the material shaft a and enhance the support stability of the material shaft a. During the threading process, after the clamping jaw assembly 332 clamps the material shaft, the telescopic member 341 drives the V-shaped roller 343 to rise to the material support shaft position. When the clamping jaw assembly needs to move in front of the V-shaped roller 343 during the threading process, the front end of the material shaft has already penetrated the core of the material roll. To avoid interference between the clamping jaw assembly 332 and the V-shaped roller 343, the telescopic member 341 drives the V-shaped roller 343 to descend, and the clamping jaw assembly 332 continues to move, completing the threading process. During the unloading process, after the clamping jaw assembly 332 clamps the material shaft and moves to the rear of the V-shaped roller 343, the telescopic member 341 drives the V-shaped roller 343 to rise and support the material shaft, and the clamping jaw assembly 332 continues to move, completing the unloading process. Among them, the V-shaped roller 43 supports the middle section of the material shaft, and the clamping jaw assembly 32 clamps the overlapping section on one side of the material shaft.

[0100] like Figure 1 As shown, the roll support device 4 comprises a fourth frame 41, a supporting mechanism 42, and a second transport vehicle 43. The supporting mechanism 42 includes two third drive members 421 and two supporting brackets 422. The two third drive members 421 correspond to the two supporting brackets 422, and the two supporting brackets 422 are respectively arranged on either side of the fourth frame 41. The third drive members 421 drive the fourth frame 41 to move upward and downward to receive the roll b transported by the second transport vehicle 43 and automatically lift the roll b to the center of the threading and drawing axis a according to its diameter. The second transport vehicle 43 is also an AGV (Automated Guided Vehicle). To prevent the supporting brackets 422 from interlocking with the second transport vehicle 43 when receiving the roll b from the second transport vehicle 43, the supporting brackets 422 are arranged alternately with the receiving structure on the second transport vehicle 43. To facilitate the movement of the second transport vehicle 43, the second transport vehicle 43 enters from the front of the fourth frame 41 and exits from the rear.

[0101] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may alter, modify, replace and modify the above embodiments within the scope of the present invention.
