Abstract
Description
Technical Field
[0001] This utility model relates to the field of roller material threading and pulling shaft technology, and in particular to an automatic roller material threading and pulling shaft device. Background Technology
[0002] In the production process of a printing and packaging plant, roll materials (such as roll plastic film and roll paper) need to undergo multiple processes, including printing, lamination, curing, and slitting. Before entering the intelligent curing chamber after the lamination process, the roll material must be threaded through a material spool for curing. After curing, the material spool must be removed from the curing chamber to proceed to the next production step. Furthermore, other processes in the production process also frequently require threading or removing material spools.
[0003] Currently, the industry mostly uses manual feeding and manual operation for threading and unthreading rolls of material. This traditional operating mode not only results in high labor intensity for workers and low work efficiency, but also leads to high labor costs, which to some extent restricts the improvement of production efficiency.

[0053] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0054] like Figure 1-2 As shown, this utility model embodiment provides an automatic shaft threading and pulling device for roll materials. The automatic shaft threading and pulling device includes a material shaft feeding device 1, a material shaft storage and transfer device 2, and a material shaft threading and pulling device 3 arranged sequentially adjacent to each other. It may also include a roll support device 4. The material shaft feeding device 1 is used to drive the material shaft a from the lower part of the first side to the feeding point of the material shaft storage and transfer device 2 at the top of the second side.
[0055] The material shaft storage and circulation device 2 is used to store material shafts a transferred by the material shaft loading device 1 and material shafts a pulled out by the material shaft threading device 3, and / or to provide material shafts a during threading to the material shaft threading device 3. The material shaft threading device 3 is used to clamp and drive the material shafts a provided by the material shaft storage and circulation device 2 through the material roll b in the material roll support device 4, and / or to clamp and pull out the material shafts a from the material roll b in the material roll support device 4, which supports the material roll b. The material shaft storage and circulation device 2 can store new material shafts a transferred by the loading device, collect old material shafts a pulled out by the threading device, and provide material shafts a to the threading process as needed, forming a closed-loop management of material shafts a. This orderly storage and circulation mode avoids the chaos and loss caused by random stacking of material shafts a, improves the turnover efficiency and reuse rate of material shafts a, and reduces production material costs.
[0056] Through the coordinated operation of the material shaft feeding device 1, the material shaft storage and transfer device 2, the material shaft threading and pulling device 3, and the material roll support device 4, the entire process of feeding, storing, threading, pulling, and supporting the material shaft a and the material roll b is fully automated. Workers no longer need to manually move the material shaft a or repeatedly perform threading and pulling operations, freeing them from heavy physical labor and significantly reducing labor intensity.
[0057] It should be noted that the automatic shaft pulling and threading device 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 shaft pulling operation of roll b, or only for the shaft threading operation of roll b, or it can be used for working conditions where shaft pulling and shaft threading 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 placement mechanism 13. The material shaft placement mechanism 13 is located at the lower part of the first side of the first frame 11, the material shaft storage and transfer device 2 is located on the second side of the first frame 11, and the first lifting mechanism 12 is mounted on the first frame 11. Wherein, as... 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 drive members 122 and multiple moving plates 123. The two chain drive members 122 are spaced apart on the first frame 11, and the transmission path of the chain drive members 122 includes an upward vertical section located on the first side of the first frame 11, a downward vertical section located on the second side of the first frame 11 and a top horizontal transition section connecting the upward vertical section and the downward vertical section.
[0060] Multiple movable plates 123 are spaced apart on the chain drive component 122. The movable plates 123 on two chain drive components 122 correspond horizontally. The transmission path of the chain drive component 122 consists of an upward vertical section, a top horizontal transition section, and a downward vertical section. This allows the material shaft a to achieve continuous vertical upward, flipping, and vertical downward movement, ensuring the smoothness and stability of the material shaft a's transmission and preventing the material shaft a from falling or jamming during transmission. 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 moving plates 123 on the two chain transmission members 122 move up to the material shaft placement mechanism 13 in the upward vertical section to support the material shaft a on the material shaft placement mechanism 13, and drive the material shaft a to rise vertically along the upward vertical section. During the process of the material shaft a flipping from the top horizontal transition section to the downward vertical section, the material shaft a is transferred to the loading point of the material shaft storage and transfer device 2 on the top of the second side of the first frame 11.
[0061] Among them, material shaft a is used for roll plastic film or roll paper, that is, material roll b is roll plastic film or roll paper. Material shaft a is a rotating structure. Material shaft a includes a middle section and overlapping sections set on both sides of the middle section. The moving plate 123 supports the middle section of material shaft a. When it is transferred to the material shaft storage and transfer device 2 at the top of the second side of the first frame 11, the feeding point at the top of the second side supports the overlapping sections on both sides of material shaft a. Of course, in actual application, the feeding point of the material shaft storage and transfer device 2 at the top of the second side does not interfere with the downward movement of the moving plate 123.
[0062] The material shaft feeding device 1, through the cooperation of the first frame 11, the first lifting mechanism 12, and the material shaft placement mechanism 13, achieves automated operation of feeding material shaft a. The two chain drive components 122 of the first lifting mechanism 12 move synchronously, driving the moving plate 123 to move along a specific path. This automatically supports the material shaft a on the material shaft placement mechanism 13 and transports it from the lower part of the first side of the first frame 11 to the feeding point at the top of the second side, eliminating the need for manual feeding and significantly reducing the labor intensity of workers. Compared to manual feeding, the automated transmission process is continuous and stable, reducing the tedious steps and time consumption of manual operation, significantly improving the efficiency of feeding operations, and meeting the high-efficiency requirements for feeding material shaft a in scenarios such as printing and packaging plants.
[0063] like Figure 3 As shown, the chain drive component 122 includes a drive chain 1221, a driving sprocket 1222, and a driven sprocket 1223. The drive chain 1221 meshes between the driving sprocket 1222 and the driven sprocket 1223, and a movable plate 123 is mounted on the drive chain 1221. The fixed end of the first drive component 121 is mounted on the first frame 11, and the driving end of the first drive component 121 is connected to a long shaft. The driving sprockets 1222 of both chain drive components 122 are fixedly sleeved on the long shaft, and the driven sprockets 1223 are rotatably mounted on the first frame 11. After the first drive component 121 is activated, it drives the two driving sprockets 1222 to rotate synchronously through the long shaft, thereby driving the drive chain 1221 to move, achieving synchronous operation of the two chain drive components 122. Wherein, 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 connection strength. The movable plate 123 has an L-shaped structure. The supporting part 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 the upward vertical section, the supporting part of the movable plate 123 is perpendicular to the moving direction of the transmission chain 1221 and tilts inward at a certain angle, so that the material shaft a can be stably placed on the supporting part of the movable plate 123, preventing the material shaft a from sliding during the upward process and improving the stability of the support.
[0065] like Figure 4 As shown, the first lifting mechanism 12 also includes a tensioning unit 125. The driven sprocket 1223 is mounted on the tensioning unit 125 via a rotating shaft. The tensioning unit 125 is adjustablely mounted on the first frame 11. The tensioning unit 125 can employ a bolt-adjustable structure. 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, adjusting the tensioning unit 125 to move the driven sprocket 1223 away from the driving sprocket 1222 will tighten the transmission chain 1221, ensuring the reliability of the transmission.
[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 parallel to each other on the movable frame 131. The support rods 132 are inclined towards 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 distance between the two chain drive components 122 is smaller than the distance between the two support rods 132. In this way, the movable plate 123 can pass smoothly between the two support rods 132 during the 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 equipped with four moving wheels 133 and multiple first rolling wheels 134. The four moving wheels 133 are located at the four corners of the bottom of the mobile frame 131 for walking on the ground, facilitating 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 together. The first mounting frame 111 extends longitudinally, and the second mounting frame 112 extends horizontally. The first lifting mechanism 12 is disposed on the first mounting frame 111, and the second mounting frame 112 is provided with a guide rail for the first rolling wheel 134 to slide. When the movable frame 131 needs to cooperate with the first frame 11, the first rolling wheel 134 of the movable frame 131 slides along the guide rail to the designated position.
[0068] like Figure 8-10 As shown, the feeding device 1 of the material shaft also includes a locking mechanism 14, such as... 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 mounted on the second mounting bracket 112, and its telescopic end is connected to the locking plate 142. The locking plate 142 can move horizontally to engage with the movable frame 131, thereby limiting the displacement of the movable frame 131. The first telescopic member 141 can be a cylinder or a hydraulic cylinder. When the movable frame 131 is placed on the second mounting bracket 112, part of the movable frame 131 abuts against the locking plate 142. When the first telescopic member 141 retracts, it drives the movable frame 131 to move through the locking plate 142, causing the movable frame 131 to abut against the second mounting bracket 112 and fix the movable frame 131. When it is necessary to move the movable frame 131, the first telescopic member 141 extends, releasing the lock on the movable frame 131. Figure 10 The diagram shows a structure in which the movable frame 131 is locked to the locking plate 142 via the second rolling wheel 135.
[0069] like Figure 8 and Figure 11 As shown, the second mounting frame 112 is provided 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 both sides of the movement path of the movable frame 131 to guide the movement direction. The end of the guide plate 113 away from the abutment plate 114 is inclined outward to form a funnel shape, which plays a guiding role when the movable frame 131 approaches the second mounting frame 112, so that the movable frame 131 can 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 located on the side of the movable frame 131 near the second mounting bracket 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, and the rolling surface of the second rolling wheel 135 contacts the locking plate 142. When the locking mechanism 14 drives the movable frame 131 closer to the first frame 11, due to the action of the guide plate 113, the movable frame 131 will move slightly left and right during 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, reducing frictional resistance, making the locking and unlocking process smoother, and also reducing the wear of 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 (Automated Guided Vehicle). The first transport vehicle 15 is located below the material shaft placement mechanism 13. The first transport vehicle 15 carries the material shaft placement mechanism 13 and moves it, placing the material shaft placement mechanism 13 onto the second mounting frame 112. The first transport vehicle 15 can be hydraulically lifted. When it is necessary to move the material shaft placement mechanism 13, the first transport vehicle 15 is driven to a position 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, 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 onto the second mounting frame 112. It should be noted that the AGV is existing technology, and its specific structure will not be described in detail here.
[0072] like Figure 13 As shown, the material shaft storage and transfer device 2 includes a second frame 21, a first transfer mechanism 25, a second transfer mechanism 26, and a receiving mechanism 27. The first transfer mechanism 25, the second transfer mechanism 26, and the receiving mechanism 27 are mounted on the second frame 21. The second frame 21 has a first storage compartment 22, a second storage compartment 23, and a third storage compartment 24 arranged horizontally and alternately from bottom to top. By setting up three layers of storage compartments, the storage capacity of material shafts a is significantly increased compared to the traditional clip-type material shaft a compartment, solving the problem of insufficient capacity when centrally inserting or removing shafts. The lower side of the third storage compartment 24 is inclined towards the higher side of the second storage compartment 23, and the lower side of the second storage compartment 23 is inclined towards the higher side of the first storage compartment 22, allowing the material shaft a to automatically roll to the receiving position of the transfer mechanism by gravity, reducing manual intervention and improving transfer efficiency.
[0073] The lower side of the first storage bin 22 is tilted to provide the material shaft a during the threading process to the material 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 called the high side and the lower side is called the low side.
[0074] The first material transfer mechanism 25 is located on 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 on the higher side of the second storage bin 23, and is used to receive the material shaft a pulled out by the upper material shaft pulling device 3. The second material transfer mechanism 26 is located on 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. The third storage bin 24 stores the shafts a transferred by the shaft feeding device 1. The higher side of the third storage bin 24 is the feeding point of the shaft storage and transfer device 2. Part of the shafts a in the second storage bin 23 come from the shafts a transferred from the third storage bin 24, and the other part comes from the shafts a pulled out by the shaft pulling device 3 through the receiving mechanism 27. Finally, all are transferred from the second storage bin 23 to the first storage bin 22 through the second material transfer mechanism 26. The lower side of the first storage bin 22 provides the shafts a during the shaft pulling process to the shaft pulling device 3. The first material transfer mechanism 25 transfers the shafts a from the third storage bin 24 to the second storage bin 23, and the second material transfer mechanism 26 transfers the shafts a from the second storage bin 23 to the first storage bin 22. Combined with the receiving mechanism 27 receiving the shafts a pulled out by the shaft pulling device 3, a closed loop of "storage-transfer-re-storage" is formed, realizing the full automation of the shaft pulling and pulling operations.
[0075] like Figure 13 and Figure 16 As shown, the receiving mechanism 27 includes a telescopic drive unit 271, a second long shaft 272, and multiple rotating plates 273 sleeved and fixed on the second long shaft 272. The rotating plates 273 are located on the second long shaft 272 and spaced apart, supporting the middle section of the material shaft a. The second long shaft 272 is located at the end of the second storage bin 23 on the higher side 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 outside of the second storage bin 23 on the higher side. The second long shaft 272 passes through the mounting plates 274 and is rotatably connected to them. The telescopic drive unit 271 is mounted on the second frame 21. The telescopic drive unit 271 drives the second long shaft 272 to rotate, thereby simultaneously rotating the rotating plates 273 to receive the material shaft a pulled out by the upper material shaft pulling device 3 into the second storage bin 23. The rotational action precisely receives the material shaft a pulled out by the upper material roll b, preventing the material shaft a from shifting position or jamming due to free fall. The rotating plate 273 can be retracted to the underside of the storage compartment when not in operation, reducing space occupation of surrounding equipment and avoiding interference with other mechanisms during operation. For example... Figure 17As shown, in order to allow the receiving shaft a to smoothly enter the second storage bin 23, the receiving mechanism 27 also includes two guide plates 275. The two guide plates 275 are arranged opposite each other and the ends located on the high side of the second storage bin 23 form an open design, forming a physical barrier during the process of the shaft a entering the second storage bin 23, preventing the shaft a from getting stuck due to angular deviation.
[0076] like Figure 16 As shown, the telescopic drive unit 271 includes two second telescopic members 2711 and two hinge plates 2712. The two second telescopic members 2711 are respectively disposed at both ends of the second long shaft 272. The fixed end of the second telescopic member 2711 is connected to the second frame 21. One end of the hinge plate 2712 is hinged to the telescopic end of the second telescopic member 2711, and the other end of the hinge plate 2712 is connected to the second long shaft 272. The two second telescopic members 2711 are respectively connected to the second long shaft 272 through the hinge plate 2712. The bearing angle of the rotating plate 273 can be adjusted according to the different diameters of the material shaft a to ensure stable bearing under different material shaft a diameters.
[0077] like Figure 18 and Figure 19 As shown, the first material transfer mechanism 25 and the second material transfer mechanism 26 are the same, both including a linear drive A1 and a transfer frame A2. The transfer frame A2 is used to receive the material shaft a, and the fixed end of the linear drive A1 is connected to the second frame 21.
[0078] like Figure 13 and Figure 18 As shown, the telescopic end of the linear drive A1 of the first material transfer mechanism 25 drives the first transfer frame A2 of the first material transfer mechanism 25 to move vertically between the lower end of the third storage bin 24 and the higher 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 A1 of the second material transfer mechanism 26 drives the transfer frame A2 to move vertically between the lower end of the second storage bin 23 and the higher end 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 place it in the first storage bin 22.
[0079] like Figure 14 and Figure 15 As shown, the first material transfer mechanism 25 also includes a first proximity switch 251 disposed on the second frame 21. The first proximity switch 251 is disposed at the lower end of the third storage compartment 24 and is used to detect whether there is a material shaft a on the transfer frame A2 of the first material transfer 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 21. The bottom of the first connecting rod A21 is connected to the telescopic end of the linear drive A1. The two transfer plates A22 are respectively disposed on both sides of the first connecting rod A21. One side of the transfer plate A22 is provided with a stop part A221 and a groove A222 in the vertical direction. The stop part 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 stop A221 on the transfer plate A22 provides lateral restraint during the transfer of the material shaft a, preventing other material shafts a in the storage compartment from falling out. The groove A222, by matching its shape to the material shaft a it receives, provides double protection for the stability of the material shaft a during the transfer process. In this embodiment, the bottom surface of the groove A222 is a slope, so 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 dimensions of the groove A222 can be standardized according to the diameter of the material shaft a, adapting to various specifications of material shafts a and improving the versatility of the device. It should be noted that in this embodiment, the only difference between the first transfer mechanism 25 and the second transfer mechanism 26 is the position of the groove A222 on the transfer plate A22.
[0082] like Figure 18 and Figure 19 As shown, the first material transfer mechanism 25 and the second material transfer mechanism 26 also include two sets of spaced-apart first guide components A3. Each set of first guide components A3 includes a first guide rail A31, a first guide slider A32, and two first limiting plates A33. The first guide rail A31 is vertically oriented on the second frame 21, and the first guide slider A32 is disposed on the first connecting rod A21 and slidably connected to the first guide rail A31. When the linear drive A1 drives the transfer frame A2 to move vertically, 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 ensures that the transfer frame A2 does not deviate laterally during vertical movement. The two first limiting plates A33 are respectively disposed at both ends of the first guide rail A31 to limit the first guide slider A32, thereby limiting the stroke of the transfer frame A2 and ensuring that the vertical stroke of the linear drive A1 during operation ensures that the material shaft a rolls smoothly into or out of the slot.
[0083] like Figure 13As shown, to avoid interference between the transfer plate A22 in the first transfer mechanism 25 and the second transfer mechanism 26 and the storage bin during operation, and to facilitate the material shaft a rolling out of the slot, the first storage bin 22, the second storage bin 23, and the third storage bin 24 are all constructed with two spaced support rods. The support rods extend along the length of the second frame 21, and the overlapping sections on both sides of the material shaft a overlap with the support rods on both sides of the storage bin. The transfer frame A2 in the first transfer mechanism 25 and the second transfer mechanism 26 is located between the two support rods, and the groove A222 on the transfer frame A2 cooperates with the middle section of the material shaft a. When the linear drive A1 drives the transfer frame A2 to descend and transfer the material shaft a to the next storage bin, the overlapping sections at both ends of the material shaft a overlap with the two support rods 132 of the next storage bin. When the linear drive A1 descends further, the material shaft a disengages from the groove A222 of the transfer plate A22 and then enters the storage bin and rolls in the inclined direction.
[0084] like Figure 13 As shown, the support rods 132 of the second storage bin 23 and the third storage bin 24 are provided with first baffles 28 along their length. The two first baffles 28 are arranged opposite each other and form an open design, forming a physical barrier during the process of the material shaft a entering the second storage bin 23 and the third storage bin 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 and pulling device 3 includes a third frame 31, a second lifting mechanism 32 and a clamping and traversing mechanism 33. The second lifting mechanism 32 and the clamping and traversing mechanism 33 are both mounted on the third frame 31, wherein the material roll b is located on the outside of the third frame 31 and is opposite to the end of the clamping and traversing 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 supports the material shaft a. The fixed end of the second driving member 321 is connected to the third frame 31. The second driving member 321 is a double-stroke cylinder. Figure 26 and Figure 27 As shown, the telescopic end of the second driving member 321 drives the support frame 322 to move vertically between the first position, the second position, and the third position. The first position, the second position, and the third position are arranged from bottom to top in the vertical direction. The second lifting mechanism 32 can drive the support frame 322 to move vertically for feeding material roll b when it passes through the shaft in the material roll support device 4, that is, to send the material shaft a from the first position to the third position. It can also be used for receiving material roll b when it pulls out the shaft in the material roll support device 4, that is, to lower the material shaft a from the third position to the second position so that the receiving mechanism 27 of the subsequent material shaft storage and transfer device 2 can receive the material shaft a, thereby facilitating the subsequent storage of the material shaft a.
[0087] The clamping and traversing mechanism 33 includes a linear motion component 331 and a gripper assembly 332. The gripper assembly 332 is used to clamp the material shaft a. The linear motion component 331 is disposed on the third frame 31 and located above the support frame 322. The linear motion component 331 extends along the width direction of the third frame 31. The moving end of the linear motion component 331 drives the gripper assembly 332 to move horizontally and linearly along the width direction of the third frame 31 to pull out the material shaft a from the material roll b in the material roll support device 4 disposed at the end of the linear motion component 331 and place it on the support frame 322, or to insert the material shaft a provided by the material shaft feeding device 3 to the support frame 322 into the material roll b in the material roll support device 4. One end of the linear motion component 331 extends out of the third frame 31 so that the gripper assembly 332 can drive the material shaft on it to fully enter the material roll b in the material roll support device 4.
[0088] The clamping and lateral movement mechanism 33 can drive the gripper assembly 332 to move horizontally via 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 reducing labor costs, which is conducive to improving production efficiency. In this embodiment, the shaft threading and pulling device 3 achieves mechanized operation of shaft a threading and pulling through the coordinated cooperation of the third frame 31, the second lifting mechanism 32, and the clamping and lateral 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 direction 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 disposed on both sides of the second connecting rod 3221. The top of the lifting plate 3222 is recessed with an arc-shaped groove, 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 of the lifting plate 3222 is recessed with an arc-shaped groove adapted to the outer surface of the material shaft a. The lifting plate 3222 is used to receive the material shaft a provided by the material shaft pulling device 3 or the material shaft a pulled out by the clamping and traversing mechanism 33. The arc-shaped groove 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 accuracy of the position of the material shaft a when clamped by the clamping assembly. To further prevent the material shaft a from falling off when the support frame 322 receives the material shaft a in the first position, a second baffle plate 325 is provided on one side of the third frame 31. The second baffle plate 325 is positioned opposite to the support frame 322 when it is in the first position. Specifically, to prevent the material shaft a from falling off the lower side of the first storage compartment 22 in the material shaft storage and transfer device 2 when the second drive member 321 moves the support frame 322, a stop is formed on the side of the lifting plate 3222 of the support frame 322 near the material shaft feeding device 3.
[0090] like Figure 22 As shown, the second lifting mechanism 32 also includes a second proximity switch 324 disposed on the third frame 31. The second proximity switch 324 is positioned opposite to the support frame 322 when it is in the first position, and is used to detect whether the material shaft a has entered the support frame 322. This facilitates automated linkage control of the shaft insertion and removal operation, improves the intelligence level of the device, reduces the need for manual monitoring, and further enhances the automation level of production. It should be noted that the automated control logic and related programs 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 drive unit 321 drives the support frame 322 to the first position, and the material shaft a enters the arc-shaped groove of the lifting plate 3222 of the support frame 322. The second proximity switch 324 is used to detect whether the material shaft a has entered the lifting plate 3222 on the support frame 322. The second drive unit 321 drives the support frame 322 to move vertically to the third position, i.e., the shaft threading preparation position, so that the gripper assembly 332 can grip the material shaft a.
[0092] When the material roll b is pulled out by the material shaft a, the second drive member 321 drives the support frame 322 to the third position to prepare to receive the material shaft a pulled out by the gripper assembly 332. After the support frame 322 receives the material shaft a, the second drive member 321 drives the material shaft a to the second position so that the receiving mechanism 27 of the subsequent material shaft storage and transfer 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 also includes two sets of spaced-apart second guide components 323. Each set of second guide components 323 includes a second guide rail 3231 and a second guide slider 3232. The second guide rail 3231 is vertically oriented on the third frame 31, and the slider is mounted on the second connecting rod 3221 and slidably connected to the second guide rail 3231. When the second driving member 321 drives the support frame 322 to move vertically, 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 components 323 can accurately guide the movement direction of the support frame 322, effectively limiting the offset of the support frame 322, making the lifting and lowering movement of the support frame 322 more stable and smooth, and improving the stability of the second lifting mechanism 32.
[0094] In this embodiment, the second guide assembly 323 further includes a second limiting plate 3233. The second limiting plate 3233 is disposed at the top of the second guide rail 3231 to limit the movement of the second guide slider 3232. That is, the second limiting plate 3233 can limit the movement of the second guide slider 3232 to prevent the second guide slider 3232 from disengaging from the second guide rail 3231 due to excessive movement. At the same time, when the second limiting plate 3233 limits 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 shaft a is exactly at the center position of the gripper assembly 332.
[0095] like Figure 23 and Figure 24 As shown, the gripper assembly 332 includes an opening / closing drive unit 3321 and two opposing gripper units 3322. The opening / closing drive unit 3321 is a guide rail slider structure. The guide rail of the opening / 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 / closing drive unit 3321. The two moving ends on the opening / closing drive unit 3321 are respectively connected to the two gripper units 3322 and drive the two gripper units 3322 to move towards or away from each other to grip or release the material shaft a. In this embodiment, the gripper assembly 332 uses a guide rail slider structure to drive the two gripper units 3322 to move towards or away from each other, which can achieve stable gripping and releasing of the material shaft a. The opening and closing action of the gripper units 3322 is highly controllable and can adapt to the gripping requirements of material shafts a with different diameter specifications, thus improving the adaptability of the device to different material shafts a.
[0096] like Figure 23 As shown, the two gripper units 3322 have identical structures and are mirror-oriented. Each gripper unit 3322 includes a connecting plate 33221 and two gripper bodies 33222. The two connecting plates 33221 are respectively connected to the two sliders of the opening and closing drive unit 3321. The two gripper bodies 33222 are connected to the bottom end of the connecting plate 33221 and are spaced apart. The two gripper bodies 33222 in the two gripper units 3322 are arranged in a one-to-one correspondence. By setting up double gripper bodies 33222, the contact area with the material shaft a is increased, making the gripper hold the material shaft a more stable, dispersing the gripping force, reducing the risk of damage to the material shaft a due to excessive local force, and further improving the reliability of the gripping operation. Of course, to further increase the friction and prevent the material shaft a from falling, an anti-slip pad is provided on the contact surface of the gripper body 33222.
[0097] like Figure 24As shown, the gripper assembly 332 also includes a synchronization unit 3323. The synchronization unit 3323 includes a gear 33231 and two racks 33232. The two racks 33232 are respectively connected to the connecting plates 33221 of the two gripper units 3322. Both racks 33232 mesh with the gear 33231. The gear 33231 is connected to the opening and closing drive unit 3321 through the 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 gripper units 3322 to move, the synchronization unit 3323 ensures that the movements of the two gripper units 3322 remain synchronized, avoiding the material shaft a from being offset or unevenly stressed due to asynchronous movements of the gripper units 3322. This ensures the coordination and consistency of the opening and closing actions of the gripper assembly 332, and improves the gripping accuracy.
[0098] like Figure 21 As shown, in practical applications, the gripper assembly 32 holds one side of the material shaft a. Since the material shaft a is relatively long, to prevent one side of the material shaft a from tilting and failing to accurately enter the material roll b when the gripper assembly moves it, the material shaft threading and pulling device 3 also includes a guide wheel mechanism 34. The guide wheel mechanism 34 is mounted on the third frame 31 and located below the linear motion assembly 331, near the material roll b. The guide wheel mechanism 34 provides rolling support to the material shaft a when the gripper assembly 332 holds and moves it. During the movement of the material shaft a while the gripper assembly 332 holds it, the guide wheel mechanism 34 provides rolling support, sharing the weight of the material shaft a, reducing the stress on the gripper assembly 332, and preventing the material shaft a from sagging due to gravity during movement, thus affecting the threading and pulling accuracy and 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. 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 gripper assembly 332 clamps the material shaft, the telescopic component 341 drives the V-shaped roller 343 to rise to the material shaft support position. When the gripper assembly needs to move in front of the V-shaped roller 343 during threading, the front end of the material shaft has already been inserted into the core of the material roll. To avoid interference between the gripper assembly 332 and the V-shaped roller 343, the telescopic component 341 drives the V-shaped roller 343 to descend, while the gripper assembly 332 continues to move, completing the threading process. During the unloading process, after the gripper assembly 332 clamps the material shaft and moves it behind the V-shaped roller 343, the telescopic component 341 drives the V-shaped roller 343 to rise and support the material shaft, while the gripper assembly 332 continues to move, completing the unloading process. The V-shaped roller 43 supports the middle section of the material shaft, while the gripper assembly 32 clamps the overlapping section on one side of the material shaft.
[0100] like Figure 1 As shown, the material roll support device 4 includes a fourth frame 41, a support mechanism 42, and a second transport vehicle 43. The support mechanism 42 includes two third drive members 421 and two support frames 422. The two third drive members 421 and the two support frames 422 are arranged in a one-to-one correspondence. The two support frames 422 are respectively arranged on both sides of the fourth frame 41. The third drive members 421 drive the fourth frame 41 to move up and down to receive the material roll b transported by the second transport vehicle 43, and automatically lift the material roll b to the center position of the material pull shaft a according to its diameter. The second transport vehicle 43 is also an AGV (Automated Guided Vehicle). To avoid the support frame 422 from interlocking with the second transport vehicle 43 when receiving the material roll b, the support frame 422 and the receiving structure on the second transport vehicle 43 are alternately arranged. To facilitate the movement of the second transport vehicle 43, the second transport vehicle 43 enters from the front end and exits from the rear end of the fourth frame 41.
