Description

Technical Field

[0001] This invention relates to the field of gravure printing technology, and in particular to an automatic paper feeding and loading device and method for gravure printing. Background Technology

[0002] Gravure printing is one of the key processes in banknote production. Its semi-finished products are usually stacked and stored using a paper receiving bin and a plate insertion mechanism. The specific process is as follows: after printing a certain quantity, a paper receiving panel is automatically inserted by the plate insertion machine, and the side plates are placed and fixed manually. After stacking to a certain quantity, a multi-layer combined shelf structure is formed, and the paper is temporarily stored after being sealed with straps.

[0003] Taking the banknote printing industry as an example, it still relies on manual dismantling of multi-layered modular shelf structures to neatly collect the panels and side panels for reuse. Simultaneously, banknotes need to be sequentially removed and transferred to the next process. This method is not only highly manual, requiring frequent manual intervention for panel and side panel dismantling, paper stacking, and paper transfer, resulting in high labor intensity and low efficiency, but also lacks automation. Operations such as panel and side panel status detection and paper counting lack real-time feedback, easily leading to significant production errors. Summary of the Invention

[0004] Based on this, the purpose of this invention is to provide an automatic paper feeding and loading device and method for gravure printing, which aims to solve the problem of high labor intensity in the current printing industry of manually removing the shelves of the gravure printing process for paper loading, and to improve the automation and intelligence level of printing operations.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, the present invention proposes an automatic paper handling and loading device for gravure printing, comprising a depaneling and paper picking device, a sorting device, a first transfer conveying device, a stacking device, and a second transfer conveying device. The depaneling and paper picking device picks up the sealing plates and products on the stacked gravure printing products in a preset order. The sorting device is located beside the depaneling and paper picking device to perform multi-angle and multi-directional sorting operations on the gravure printing products, wherein the sorting operation includes at least a vibration operation. The first transfer conveying device is located between the depaneling and paper picking device and the sorting device to transfer the gravure printing products processed by the depaneling and paper picking device to the sorting device. The stacking device includes a palletizing mechanism and a stacking mechanism. The palletizing mechanism is used to load the sorted gravure printing products onto pallets, and the stacking mechanism is used to stack the pallets containing the gravure printing products transferred from the palletizing mechanism. The second transfer conveying device is located between the sorting device and the palletizing mechanism to transfer the gravure printing products processed by the sorting device to the palletizing mechanism.

[0006] The automatic paper handling and loading device for gravure printing according to embodiments of the present invention has at least the following beneficial effects: Through the designed plate-removing and paper-picking device, automated and sequential picking of the top sealing plates and products of stacked gravure printing is achieved, replacing the original manual removal operation. Simultaneously, in conjunction with the first transfer conveyor device, the gravure printing products after plate removal are automatically transferred to the sorting device. The sorting device can perform automated sorting operations on the transferred gravure printing products from multiple angles and directions; that is, at least through vibration operation, the gravure printing products can be flattened and gaps removed, ensuring uniformity and providing high-quality input for subsequent processes. Simultaneously, in conjunction with the second transfer conveyor device, the sorted gravure printing products are automatically transferred to the palletizing device. Finally, through the palletizing device integrating the palletizing mechanism and the stacking mechanism, the sorted gravure printing products are fully processed. The automated tray loading operation of printed materials and the automated stacking operation of full trays of gravure printed materials replace the original manual paper stacking process. In summary, the first and second transfer conveying devices provide automated connections between the unpacking to sorting and sorting to stacking processes, respectively, enabling seamless connection of key processes such as unpacking, sorting, traying, and stacking. The entire set of devices works in concert to form a highly continuous and automated processing flow, eliminating the frequent and heavy manual labor in the original process, such as manually removing the sealing plates and products, manually picking and transferring gravure printed materials, manually sorting paper, and manually stacking. It overcomes the intermittent and speed limitations of manual operation, improves production efficiency and processing continuity, and at the same time, automated processing can ensure the neatness of the paper stacks, ensuring the stability and consistency of the gravure printed materials during the processing.

[0007] In addition, the automatic paper feeding and loading device for gravure printing according to the present invention may also have the following additional technical features: Furthermore, the depaneling and paper-retrieving device includes a first shelf gripping mechanism and a second shelf gripping mechanism; wherein, the first shelf gripping mechanism is provided with a first gripping part, a support part, and a clamping part, the first gripping part sequentially picks up the side panels and classifies and transfers them to the support part and the clamping part; the second shelf gripping mechanism is provided with a second gripping part, the second gripping part picks up the sealing plate and the product.

[0008] Furthermore, the paper removal device also includes a flipping structure, which is used to flip half a circle to remove the gravure prints on the top panel and side panels. The flipping structure includes a driving assembly and a first fork arm. The first fork arm is rotatably mounted on the driving assembly. The driving assembly is used to drive the first fork arm to move and rotate horizontally. The first fork arm is provided with a third gripping part that can move closer to or further away from each other.

[0009] Furthermore, the sorting device includes a machine base, a support assembly, two opposing second forks, and a vibration device. The support assembly is movably mounted on the machine base to adjust the pitch and roll angles. Both second forks are movably mounted on the support assembly to move closer to or further away from each other. The vibration device is mounted on the machine base to vibrate the stack of paper held by the second forks.

[0010] Furthermore, the finishing device also includes an ion air outlet device, which is disposed on the machine platform to blow ion air onto the gravure print held by the second fork arm.

[0011] Furthermore, the coding disc mechanism includes a positioning platform and a gripping component. The positioning platform horizontally holds the gravure prints received from the second transfer conveying device. The coding disc is vertically movably mounted on the positioning platform. The gripping component is mounted on the positioning platform and has a fourth gripping part.

[0012] Furthermore, the stacking mechanism includes a chopping tray frame, a horizontal positioning component, and a vertical pushing component. The chopping tray frame is arranged side by side with the positioning platform. The horizontal positioning component is movably mounted on the chopping tray frame in the horizontal direction to support the chopping tray when it moves to the lowest position and transfer the chopping tray to the bottom of the chopping tray frame. The vertical pushing component is movably mounted on the chopping tray frame in the vertical direction to perform a stacking operation on the chopping trays transferred by the horizontal positioning component from top to bottom.

[0013] Furthermore, the first transplanting and conveying device includes a third fork arm disposed between the paper removal device and the sorting device, and a fourth fork arm that is respectively inserted and fitted with the first fork arm and the third fork arm.

[0014] Furthermore, the second transplanting and conveying device includes a fifth fork arm disposed between the sorting device and the palletizing device, and a sixth fork arm that interlocks and fits with the second fork arm and the fifth fork arm respectively.

[0015] Secondly, the present invention also proposes an automatic paper feeding and loading method for gravure printing, applied in the aforementioned automatic paper feeding and loading device for gravure printing, the method comprising: The deplate and paper-retrieving device is controlled to pick up the sealing plates and products on the stacked gravure prints in a preset order; The first transfer conveyor is controlled to transfer the desealed plate and the gravure print of the product to the sorting device; The finishing device is controlled to perform multi-angle and multi-directional finishing operations on the gravure printed product after the sealing plate and the product are removed, wherein the finishing operation includes at least a vibration operation; The second transfer conveyor is controlled to transfer the gravure prints processed by the sorting device to the stacking mechanism. The palletizing device is controlled to perform tray loading operations on the sorted gravure prints and to stack the trays containing the gravure prints.

[0016] The automatic paper feeding and loading method for gravure printing according to embodiments of the present invention has at least the following beneficial effects: By defining a well-defined sequence of control steps, the entire process of gravure printing, from unpacking to sorting and then to palletizing, is fully automated. This eliminates the heavy and error-prone manual labor involved in the original process, such as manually removing the seals and products, manually handling and transferring gravure prints, manually sorting paper, manually palletizing, and manually stacking. It overcomes the intermittency and speed bottleneck of manual operation, increases the throughput per unit time and the continuity of production. At the same time, the standardized automated operation reduces the differences caused by human factors, improves the neatness of the gravure print stack shape, and enhances the stability and consistency of the final stack.

Specifically, taking banknotes as an example, each layer of the container-type shelf structure 100 is surrounded by two sizes of side panels 110 to form an area for placing stacks of paper 140. Each layer of the container-type shelf structure 100 has an upper panel 120 and a lower panel 130 on its upper and lower sides, respectively, to cover the upper and lower openings of the area for placing stacks of paper 140. It should be noted that the container-type shelf structure 100 is not limited to holding banknotes; it can also hold other intaglio printed materials.

[0022] Please refer to Figures 2 to 14 The present invention provides an automatic paper feeding and loading device for gravure printing, comprising a paper disassembly and picking device, a sorting device 500, a first transfer and conveying device, a stacking device 600, and a second transfer and conveying device.

[0023] The demounting and paper-picking device picks up the sealing plates and products from the stacked gravure prints in a preset sequence. A sorting device 500 is located beside the demounting and paper-picking device to perform multi-angle and multi-directional sorting operations on the gravure prints. The sorting operation includes at least a vibration operation to achieve the function of shaking, loosening, and aligning the prints. A first transfer conveying device is located between the demounting and paper-picking device and the sorting device 500 to transfer the gravure prints processed by the demounting and paper-picking device to the sorting device 500. The palletizing device 600 includes a palletizing mechanism and a stacking mechanism. The palletizing mechanism is used to load the sorted gravure prints onto empty pallets 641. The stacking mechanism is used to stack the pallets 641 containing the gravure prints transferred from the palletizing mechanism to facilitate transportation and storage. A second transfer conveying device is located between the sorting device 500 and the palletizing mechanism to transfer the gravure prints processed by the sorting device 500 to the palletizing mechanism.

[0024] In some alternative embodiments, such as Figures 2 to 5 The paper removal device includes a first shelf gripping mechanism 200 and a second shelf gripping mechanism 300.

[0025] Specifically, the first shelf gripping mechanism 200 is provided with a first gripping part, a support part and a clamping part. The first gripping part sequentially picks up the side panels and transfers them to the support part and the clamping part in a classified manner.

[0026] The second shelf gripping mechanism 300 is equipped with a second gripping part, which picks up the sealing plate and the product.

[0027] In some alternative embodiments, such as Figures 2 to 5 The paper removal and disassembly device also includes a flipping mechanism 400.

[0028] In specific operation, firstly, the second shelf gripping mechanism 300 picks up the upper panel 120 corresponding to each layer of paper stack 140 of the container shelf structure 100. Then, the flipping mechanism 400 transfers the paper stack 140 after removing the upper panel 120 to the second shelf gripping mechanism 300, performs a half-turn flip, and places the upper panel 120 on the second loading platform 340. After that, the first shelf gripping mechanism 200 picks up the side panel 110 and classifies and transfers it to the support and clamping parts, and finally places it on the first loading platform 240. Then, the second shelf gripping mechanism 300 picks up each layer of paper stack 140 and the corresponding lower panel 130 of the container shelf structure 100. Then, the flipping mechanism 400 transfers the paper stack 140 after removing the lower panel 130 to the second shelf gripping mechanism 300, performs a half-turn flip, and places the lower panel 130 on the second loading platform 340.

[0029] It should be noted that in this embodiment, an automatic control system is required to control the first shelf gripping mechanism 200, the second shelf gripping mechanism 300, the flipping mechanism 400, the sorting device 500, and the palletizing device 600 according to a set procedure, such as a PLC control module. Simultaneously, the automatic control system also needs to acquire the working status of each device mechanism through sensors, such as position sensors. Since the automatic control system and position sensors are existing technologies in the field of automation control, they will not be elaborated upon here.

[0030] In some alternative embodiments, such as Figure 4 , Figure 5 As shown, the first shelf gripping mechanism 200 includes a first shelf 210, a temporary platform 220, a first gripper assembly 230, a first loading platform 240, and a second gripper assembly 250.

[0031] Specifically, the first shelf 210 is a frame structure, and the temporary platform 220 is located on the upper part of the first shelf 210. The temporary platform 220 is provided with a support part and a clamping part whose positions do not interfere with each other. The support part and the clamping part are used to horizontally clamp the end face of the side plate 110.

[0032] For example, the temporary platform 220 is provided with support columns 221 of equal height and clamping grooves composed of clamping plates 222 arranged opposite each other. One type of side plate 110 of the same specification is placed in the clamping groove, and the remaining type of side plate 110 is placed on the support column 221.

[0033] The first gripper assembly 230 is provided with a first gripper portion. When the first gripper assembly 230 is in working state, the first gripper portion sequentially picks up the side plate 110 corresponding to each layer of paper stack 140 of the container shelf structure 100 and transfers it to the support portion and the clamping portion.

[0034] The first loading platform 240 is located at the bottom of the first shelf 210. The first loading platform 240 has a first platform for loading the side panel 110 and a second platform for loading the top panel 120.

[0035] The second gripper assembly 250 is provided with a second gripper portion. When the second gripper assembly 250 is in working state, the second gripper portion sequentially picks up the upper panel 120 of the temporary stage 220 and classifies and transfers it to the second table surface on the corresponding first loading stage 240.

[0036] Optionally, to facilitate the automatic transport of the top panel 120 and side panel 110, the first loading platform 240 can be an AGV (Automated Guided Vehicle). AGVs are transport vehicles equipped with electromagnetic or optical automatic guidance devices, capable of traveling along a prescribed guidance path, and possessing safety protection and various transfer functions. In industrial applications, they are handling vehicles that do not require a driver and are powered by rechargeable batteries.

[0037] In some alternative embodiments, such as Figure 4 As shown, both the first gripper assembly 230 and the second gripper assembly 250 include a first horizontal movement component and a first vertical movement component 251.

[0038] Specifically, the first horizontal moving component is movably mounted on the first shelf 210, the first vertical moving component 251 is mounted on the first horizontal moving component, and the first gripper portion and the second gripper portion are both mounted on the corresponding first vertical moving component 251.

[0039] In this embodiment, when the first horizontal moving component is in the working state, both the first gripper and the second gripper can move along... Figure 2The first vertical moving component 251 moves along the X-axis direction; when the first vertical moving component 251 is in the working state, both the first gripper and the second gripper can move along the X-axis direction. Figure 2 It moves along the Z-axis.

[0040] Optionally, both the first horizontal moving component and the first vertical moving component 251 can be moving devices such as linear moving modules, moving structures with lead screws and rotary drives, or linear motors. In addition, pneumatic grippers, hydraulic grippers, electric grippers, and other automatic gripping devices can be set on the linear moving module to form the first gripper part and the second gripper part in sequence.

[0041] In some alternative embodiments, such as Figure 6 , Figure 7 As shown, the second shelf gripping mechanism 300 includes a second shelf 310, a third gripper assembly 320 disposed opposite to it, a suction cup 330, and a second loading platform 340.

[0042] Specifically, both third gripper assemblies 320 are synchronously and vertically movable on the second shelf 310. When both third gripper assemblies 320 are in operation, they can move closer to each other and further apart in the vertical direction. Each third gripper assembly 320 has a synchronously horizontally moving third gripper portion, allowing the two third gripper portions to move closer to or further apart, thereby gripping the upright stack of paper 140 supported by the lower panel 130.

[0043] The suction cup 330 is movably mounted on the second shelf 310. When the suction cup 330 is in working condition, it can move in the horizontal and vertical directions to sequentially pick up the lower panel 130 corresponding to each layer of paper stack 140 of the container shelf structure 100 and transfer it to the third gripper assembly 320. At this time, the two oppositely arranged third grippers are controlled to move closer to each other until they clamp the edge of the lower panel 130.

[0044] The second loading platform 340 is located at the bottom of the second shelf 310 and corresponds to the position of the third gripper assembly 320. The second loading platform 340 is provided with a third table surface for loading the lower panel 130.

[0045] In this embodiment, the third gripper holding the lower panel 130 moves downward until the lower panel 130 is placed on the third platform of the second loading table 340. Then, the two opposing third grippers are controlled to move away from each other and move upward to pick up the next lower panel 130.

[0046] Optionally, to facilitate the automatic transport of the lower panel 130, the second loading platform 340 can be an AGV trolley, with the same principle as above.

[0047] In some alternative embodiments, such as Figure 7 As shown, the third gripper includes a vertically arranged first plate frame 331, first claw plates 332 disposed at the upper and lower ends of the first plate frame 331, a first driver that drives the first plate frame 331 to move horizontally, and a second driver that drives the two first claw plates 332 to move closer to each other and further away from each other. The first driver is fixed on the second shelf 310.

[0048] In this embodiment, when it is necessary to clamp the lower panel 130, the first driver is first controlled to drive the two oppositely arranged first plate holders 331 to move closer to each other until the middle part of the first plate holders 331 is attached to the edge of the lower panel 130. Then, the second driver is controlled to drive the two oppositely arranged first claw plates 332 to move closer to each other until the two first claw plates 332 clamp the upper and lower surfaces of the edge of the lower panel 130.

[0049] Optionally, the first driver can be a telescopic cylinder, a telescopic hydraulic cylinder, a telescopic motor, or other driving device; similarly, the second driver can also be a telescopic cylinder, a telescopic hydraulic cylinder, a telescopic motor, or other driving device.

[0050] In some alternative embodiments, the first plate frame 331 moves up and down via a lifting device. Optionally, the lifting device may be a linear motion module, such as a linear motor.

[0051] In some alternative embodiments, such as Figure 6 , Figure 8 As shown, the flipping mechanism 400 includes a third driver 410 and a first fork arm 420.

[0052] Specifically, the third actuator 410 is mounted on the second shelf 310, and the first fork arm 420 is rotatably mounted on the third actuator 410. The first fork arm 420 is equipped with third gripping parts that can move closer to or further away from each other. During operation, the third gripping parts are controlled to grip the paper stack 140, and then the third actuator 410 is controlled to first drive the first fork arm 420 to move horizontally, and finally the third actuator 410 is controlled to drive the first fork arm 420 to rotate half a revolution, so that the lower panel 130 faces upward.

[0053] Optionally, the third drive 410 can be a drive device such as a cylinder, hydraulic cylinder, or motor capable of rotary linear motion.

[0054] Preferably, the first fork arm 420 adopts a hollow design. By reducing the contact area between the paper and the supporting surface of the first fork arm 420, the paper will undergo reasonable deformation in the hollow area due to the lack of support. This can reduce the risk of relative slippage of banknotes during the conveying process.

[0055] In some alternative embodiments, such as Figure 6 , Figure 8As shown, the first fork arm 420 is provided with opposing fourth gripper assemblies. Specifically, the two fourth gripper assemblies are provided with fourth gripper portions that move synchronously horizontally and synchronously vertically. When the fourth gripper assemblies are in the working state, the two fourth gripper portions move closer to or further away from each other and can move up and down together.

[0056] The first transfer conveyor is used to transport the paper stack 140 with the lower panel 130 removed to the sorting device 500.

[0057] In some alternative embodiments, such as Figure 8 As shown, the fourth gripper includes a vertically arranged second plate frame 431, a concave groove plate 432 disposed at the lower end of the second plate frame 431, a fourth driver for driving the second plate frame 431 to move vertically, and a fifth driver for driving the concave groove plate 432 to move horizontally.

[0058] Specifically, the second plate frame 431 is fixed on the first fork arm 420, and the width of the clamping groove of the concave groove plate 432 matches the thickness of the lower panel 130.

[0059] Optionally, the fourth actuator can be a telescopic cylinder, a telescopic hydraulic cylinder, a telescopic motor, or other driving device; similarly, the fifth actuator can also be a telescopic cylinder, a telescopic hydraulic cylinder, a telescopic motor, or other driving device.

[0060] In this embodiment, after the first shelf gripping mechanism 200 removes the side plate 110 of the current layer of paper stack 140, the third driver 410 drives the first fork arm 420 to move horizontally to directly above the current layer of paper stack 140. Then, the fourth gripper moves downward until the concave groove plate 432 of the fourth gripper matches the horizontal position of the lower panel 130. Then, the two sets of concave groove plates 432 move closer to each other until they clamp the edge of the lower panel 130. Then, the fourth gripper moves upward, and finally, the third driver 410 drives the first fork arm 420 to move horizontally to the flipping station. After the flipping is completed, the fourth gripper releases its gripping state, and the first transfer conveying device moves the paper stack 140 of this layer to the sorting device 500.

[0061] In some alternative embodiments, such as Figure 9 , Figure 10 As shown, the sorting device 500 includes a machine base 510, a support assembly, a second fork arm 540 arranged opposite to it, and a vibration device.

[0062] Specifically, the support assembly is movably mounted on the machine base 510, and both second forks 540 are movably mounted on the support assembly to move closer to or further away from each other. By movably mounting the support assembly on the machine base 510, the pitch and roll angles of the paper stacks 140 held on the two second forks 540 can be adjusted.

[0063] The vibration device is installed on the machine base 510. When the vibration device is in working condition, it can shake and disperse the paper stack 140 held by the second fork arm 540.

[0064] Alternatively, the vibration device can be a vibration motor or other vibration device.

[0065] In some alternative embodiments, such as Figure 9 , Figure 10 As shown, the support assembly includes a rotating arm 520 and a support arm 530.

[0066] Specifically, the rotating arm 520 is rotatably mounted on the machine base 510 to adjust the pitch angle of the rotating arm 520 in the vertical direction, the support arm 530 is rotatably mounted on the rotating arm 520 to adjust the roll angle of the support arm 530 in the horizontal direction, and both second fork arms 540 are movably mounted on the support arm 530.

[0067] In this embodiment, when the two second forks 540 are in working state, the two second forks 540 move closer to each other and clamp the paper stack 140 from top to bottom, or move away from each other. At this time, the lower second fork 540 temporarily supports the paper stack 140.

[0068] Preferably, the second fork arm 540 adopts a hollow design. By reducing the contact area between the paper and the support surface of the second fork arm 540, the paper will undergo reasonable deformation in the hollow area due to the lack of support. This can reduce the risk of relative slippage of banknotes during the transportation process.

[0069] In some alternative embodiments, the sorting device 500 further includes an ion air outlet device disposed on the machine base 510.

[0070] In this embodiment, the positive and negative ion streams generated by the high-voltage ionization of air by the ion air outlet device can be blown directionally onto the surface of the banknotes to prevent them from sticking together. Moreover, due to the vibration of the vibration device and the clamping action of the second fork arm 540, the separated banknotes can be effectively aligned.

[0071] After the sorting device 500 completes the processing, the sorted paper stack 140 is transported to the palletizing device 600 by the second transfer conveyor.

[0072] In some alternative embodiments, the encoder mechanism includes a positioning platform and a gripping component.

[0073] Specifically, the positioning platform 620 horizontally places the gravure prints transferred from the second transfer conveyor, the chopping tray is vertically movable on the positioning platform 620, the gripping component is located on the positioning platform 620, and the gripping component is provided with a fourth gripping part.

[0074] In some alternative embodiments, such as Figures 11 to 14As shown, the stacking mechanism also includes a third shelf 610, and a positioning platform 620 is horizontally movably mounted on the third shelf 610 to receive the paper stack 140 conveyed by the second transfer conveyor.

[0075] In some alternative embodiments, such as Figures 11 to 14 As shown, the gripping assembly includes a fifth gripper assembly and a second vertical movement assembly 640. Specifically, the fifth gripper assembly is mounted on the third shelf 610, and the fifth gripper assembly has a fifth gripper portion that moves vertically relative to each other. The two fifth gripper portions move closer to each other or further apart in the vertical direction, so as to grip the paper stack 140 on the positioning platform 620.

[0076] The second vertical moving component 640 is vertically movable on the third shelf 610, and the chopping plate 641 is placed on the second vertical moving component 640.

[0077] To prevent the chopping plate 641 from moving on the second vertical moving component 640, in some optional embodiments, such as Figures 11 to 14 As shown, the gripping assembly also includes horizontally movable and relatively positioned positioning grippers 650.

[0078] Specifically, the positioning gripper 650 is mounted on the third shelf 610. When the second vertical moving component 640 moves to the first preset height, the positioning grippers 650 on both sides move closer to each other until the positioning gripper 650 clamps the limiting area on the chopping plate 641.

[0079] In some alternative embodiments, such as Figures 11 to 14 As shown, the pallet stacking mechanism includes a pallet chopping frame 660, a horizontal positioning component, and a vertical pushing component.

[0080] Specifically, the chopping plate rack 660 and the third shelf 610 are arranged side by side, and the horizontal positioning component is movably mounted on the chopping plate rack 660 in the horizontal direction to support the chopping plate 641 when the chopping plate 641 moves to the lowest position (second preset height, the second preset height is lower than the first preset height) and transfer the chopping plate 641 to the bottom of the chopping plate rack 660.

[0081] The vertical push component is mounted on the chopping plate rack 660 in a vertical direction to stack the chopping plates 641 that are transferred by the horizontal positioning component from top to bottom.

[0082] In this embodiment, after the paper stack 140 is placed on the chopping tray 641, the positioning grippers 650 on both sides move away from each other. Then, the second vertical moving component 640 moves the chopping tray 641 downward to the second preset height at the bottom of the third shelf 610. When the horizontal positioning component is in working state, the horizontal positioning component first moves the chopping tray rack 660 at the bottom of the third shelf 610 to the bottom of the chopping tray rack 660, and then the vertical pushing component stacks the chopping trays 641 supporting the paper stack 140 layer by layer.

[0083] Optionally, the second vertical moving component 640 may be a lifting structure with a lead screw and a rotary drive, a linear moving module, or other moving devices.

[0084] In some alternative embodiments, such as Figure 12 As shown, the fifth gripper includes a vertically arranged third plate frame 631, second gripper plates 632 disposed at the upper and lower ends of the third plate frame 631, and a sixth driver that drives the two second gripper plates 632 to move closer to each other and further away from each other. The third plate frame 631 is fixed on the third shelf 610.

[0085] In this embodiment, when it is necessary to clamp the paper stack 140, the positioning platform 620 is first controlled to move to the side of the second claw plate 632, and then the sixth driver is controlled to drive the two opposing second claw plates 632 to move closer to each other until the two first claw plates 332 clamp the upper and lower surfaces of the paper stack 140.

[0086] Alternatively, the sixth actuator can be a telescopic cylinder, a telescopic hydraulic cylinder, a telescopic motor, or other drive devices.

[0087] Preferably, in order to accurately control the position of the positioning platform 620 and reduce the risk of banknote slippage during the movement of the positioning platform 620, the positioning platform 620 adopts an air-floating platform.

[0088] It should be noted that the core component of the air-floating platform is the air-floating guide rail system, the principle and specific structure of which are existing technologies and will not be described in detail here.

[0089] In some alternative embodiments, such as Figure 11 As shown, the palletizing device 600 also includes an automatic strip placement mechanism 680. This mechanism automatically cuts, positions, and places the sealing strips (such as paper banknote strapping) during the banknote bundling process, replacing manual adhesive / strip application. It should be noted that the automatic strip placement mechanism 680 is prior art and will not be described in detail here.

[0090] In some alternative embodiments, such as Figure 13 , Figure 14 As shown, the vertical pushing component includes a second horizontal moving component 671, a third vertical moving component 672, a first telescopic component 673, and a second telescopic component 674.

[0091] Specifically, the second horizontal moving component 671 is horizontally movable at the bottom of the chopping plate rack 660. When the second horizontal moving component 671 is in working state and the second vertical moving component 640 moves to the second preset height, the second horizontal moving component 671 supports the chopping plate 641 and transfers it to the bottom of the chopping plate rack 660.

[0092] The third vertical moving component 672 is vertically movable on the chopping plate rack 660, and the first telescopic component 673 is disposed on the third vertical moving component 672. The first telescopic component 673 is provided with a first telescopic part that extends and retracts in the horizontal direction, and the second telescopic component 674 is disposed on the chopping plate rack 660, and the second telescopic component 674 is provided with a second telescopic part that extends and retracts in the horizontal direction.

[0093] When the second horizontal moving component 671 supports the chopping tray 641 and transfers it to the bottom of the chopping tray frame 660, the first telescopic component 673 first operates to clamp the chopping tray 641. Then, the third vertical moving component 672 drives the first telescopic component 673 to move upward to a certain height. After that, the second telescopic component 674 operates to clamp the chopping tray 641. At this time, the first telescopic component 673 can be released from the clamping state. Then, the third vertical moving component 672 drives the first telescopic component 673 to move downward to the initial position to clamp the next stack of paper 140.

[0094] Optionally, both the first telescopic device 673 and the second telescopic device 674 can be telescopic power devices such as telescopic cylinders, telescopic motors, and telescopic cylinders. The second horizontal moving component 671 and the third vertical moving component 672 can be moving devices such as linear moving modules and moving structures with lead screws and rotary drives.

[0095] In some alternative embodiments, such as Figure 1 As shown, the first transplanting and conveying device includes a third fork arm 710 disposed between the paper removal device and the sorting device 500, and a fourth fork arm 730 that is inserted and fitted with the first fork arm 420 and the third fork arm 710 respectively. The fourth fork arm 730 can move in the horizontal and vertical directions.

[0096] In this embodiment, when it is necessary to move the paper stack 140 supported on the first fork arm 420 to the third fork arm 710, the fourth fork arm 730 first moves to directly below the first fork arm 420, then the fourth fork arm 730 passes through the first fork arm 420 to lift the paper stack 140 upwards, then the fourth fork arm 730 moves to the left from above the first fork arm 420 until it moves to the third fork arm 710, then the fourth fork arm 730 moves downwards and passes through the third fork arm 710, at which point the paper stack 140 falls onto the third fork arm 710, and finally the first transfer device transports the paper stack 140 with the lower panel 130 removed to the sorting device 500.

[0097] In some alternative embodiments, such as Figure 1 As shown, the second transplanting and conveying device includes a fifth fork arm 720 disposed between the sorting device 500 and the palletizing device 600, and a sixth fork arm 740 that is inserted and attached to the second fork arm 540 and the fifth fork arm 720 respectively. The sixth fork arm 740 can move in the horizontal and vertical directions.

[0098] In this embodiment, when it is necessary to move the paper stack 140 supported on the second fork arm 540 to the fifth fork arm 720, the sixth fork arm 740 first moves to directly below the second fork arm 540, then the sixth fork arm 740 passes through the second fork arm 540 to lift the paper stack 140 upwards, then the sixth fork arm 740 moves to the left from the middle of the two second fork arms 540 until it moves to the fifth fork arm 720, then the sixth fork arm 740 moves downwards and passes through the fifth fork arm 720, at which point the paper stack 140 falls on the fifth fork arm 720, and finally the sorted paper stack 140 is transported to the palletizing device 600 by the second transfer conveyor.

[0099] It should be noted that the third fork arm 710, the fourth fork arm 730, the fifth fork arm 720, and the sixth fork arm 740 all adopt a hollow design. The hollow area of ​​the fourth fork arm 730 complements the hollow areas of the first fork arm 420 and the third fork arm 710, and the hollow area of ​​the sixth fork arm 740 complements the hollow areas of the second fork arm 540 and the fifth fork arm 720.

[0100] In some alternative embodiments, such as Figure 6 , Figure 9 As shown, both the fourth fork arm 730 and the sixth fork arm 740 can move horizontally via the first guide rail moving module 741, for example, a linear motor.

[0101] In some alternative embodiments, both the fourth fork arm 730 and the sixth fork arm 740 can move vertically via a first guide rail moving module, such as a linear motor.
