[0034] This invention proposes a paper sheet machine 100.

[0035] Please refer to Figures 1 to 12. In one embodiment of the present invention, the paper sheet machine 100 includes: a storage device 1, a picking device 2, and a conveying device 3; the storage device 1 includes at least one set of storage modules 11, which are used to store corner protector paperboard 20 and convey the corner protector paperboard 20 along a first direction; the picking device 2 is disposed on one side of the storage device 1 along the first direction, and the picking device 2 includes at least one set of picking modules 21, which include a picking mechanism 211 and a receiving component 212. Material 212 has a transition groove 2121 for accommodating corner protector cardboard 20. Material picking mechanism 211 is used to sequentially pick up corner protector cardboard 20 from storage device 1 and transfer it to transition groove 2121. Conveying device 3 is located on one side of picking device 2 along the second direction. Conveying device 3 includes at least one set of conveying modules 31. Conveying module 31 is used to pick up corner protector cardboard 20 from transition groove 2121 along the second direction and transfer it to a preset station. The first direction intersects with the second direction.

[0036] In this embodiment, the storage device 1 is a cardboard storage and primary supply unit. Each storage module 11 in the device includes a vertically oriented storage bin, which can hold multiple corner protector cardboard sheets 20 of the same specification. The bottom or outlet of the storage bin is connected to a pushing mechanism driven by a stepper motor or cylinder. The storage mechanism is used to store a certain number of corner protector cardboard sheets 20 and pushes the foremost cardboard sheet horizontally to a preset position along a preset first direction for subsequent gripping. The picking device 2 has at least one picking module 21 corresponding to the storage module 11. Each picking module 21 includes a picking mechanism 211 and a receiving component 212. The receiving component 212 has a groove whose shape matches the shape of the corner protector cardboard sheet 20. This groove is configured as a transition groove 2121 for temporarily accommodating and positioning a single corner protector cardboard sheet 20. The picking mechanism 211 can be a vacuum suction cup array or a mechanical gripper. After the storage module 11 pushes a piece of cardboard to the picking position, the picking mechanism 211 moves to one side of the cardboard along the first direction and picks up the cardboard by negative pressure adsorption or mechanical clamping. Then, it transfers and places the cardboard into the transition groove 2121 of the receiving component 212. The transition groove 2121 is used to realize the positioning and posture correction of the cardboard. The input end of the conveying device 3 corresponds to the position of the transition groove 2121. After the corner protector cardboard 20 falls into the transition groove 2121, it is used to remove the cardboard from the transition groove 2121 and drive the cardboard to move along the second direction intersecting the first direction, and transfer and place it to the preset work station.

[0037] The technical solution of the present invention employs a storage device 1, a picking device 2, and a conveying device 3 in a paper machine 100. The storage device 1 includes at least one set of storage modules 11, which are used to store corner protector paperboard 20 and convey the corner protector paperboard 20 along a first direction. The picking device 2 is located on one side of the storage device 1 along the first direction and includes at least one set of picking modules 21. The picking module 21 includes a picking mechanism 211 and a receiving member 212. The receiving member 212 has a transition groove 2121 for accommodating the corner protector paperboard 20. The picking mechanism 211 is used to sequentially pick up the corner protector paperboard 20 from the storage device 1 and transfer it to the transition groove 2121. The conveying device 3 is located on the picking device. 2. Along one side of the second direction, the conveying device 3 includes at least one set of conveying modules 31. The conveying modules 31 are used to take out the corner protector paperboard 20 from the transition trough 2121 along the second direction and transfer it to a preset station. This allows the paper machine 100 to store and convey the corner protector paperboard 20 through the storage device 1, and to take out the corner protector paperboard 20 from the storage device 1 in sequence through the picking device 2 and put it into the transition trough 2121. Then, the conveying device 3 transfers the corner protector paperboard 20 from the transition trough 2121 to the preset position in sequence. The conveying device 3 can extend the conveying path of the paperboard and can adjust the output direction and path of the paperboard as needed to accurately convey the corner protector paperboard 20 to the preset position.

[0038] In one embodiment, the conveying device 3 further includes a first frame 32, and the conveying module 31 is mounted on the first frame 32. The conveying module 31 includes a first conveying component 311 and a second conveying component 312. The second conveying component 312 is located on the side of the first conveying component 311 away from the material picking device 2. The first conveying component 311 has a first conveying groove 3111 that communicates with the transition groove 2121, and the second conveying component 312 has a second conveying groove 3121 that communicates with the first conveying groove 3111. The first conveying component 311 connects to the corner protector paperboard 20 through the first conveying groove 3111 and drives the corner protector paperboard 20 to move toward the second conveying groove 3121. The second conveying component 312 connects to the corner protector paperboard 20 through the second conveying groove 3121 and drives the corner protector paperboard 20 to move toward the wrapping device.

[0039] In this embodiment, the conveying module 31 is mounted on a specific mounting surface of the first frame 32. The conveying module 31 includes a first conveying assembly 311 and a second conveying assembly 312. The first conveying assembly 311 is located on the side near the picking device 2 and has a first conveying groove 3111 that is aligned and connected with the transition groove 2121 on the receiving member 212 in the picking device 2 in terms of horizontal height and axis. The width of the first conveying groove 3111 is slightly larger than the thickness of the corner protector cardboard 20, and its length extends along a predetermined conveying path. The first conveying assembly 311 can be a motor-driven synchronous belt, friction wheel, or small roller array, mounted on both sides of the first conveying groove 3111 to receive the corner protector cardboard 20 that is moved into the transition groove 2121, and to drive it to move away from the picking device 2 along the first conveying groove 3111 by friction. The second conveying assembly 312 is located on the side of the first conveying assembly 311 away from the material handling device 2. It has a second conveying trough 3121 that connects and docks with the outlet end of the first conveying trough 3111. The second conveying trough 3121 is similar to the first conveying trough 3111 in cross-sectional shape and function, but its extension direction can be adjusted according to actual layout requirements. The second conveying assembly 312 is used to receive the corner protector cardboard 20 sent out from the first conveying trough 3111, and continues to drive the corner protector cardboard 20 along a set path through its second conveying trough 3121, ultimately accurately transferring the corner protector cardboard 20 to the designated position. The connection between the two conveying assemblies ensures that the corner protector cardboard 20 will not get stuck or deviate in posture during the transfer process, thereby realizing the continuous automated transfer of the corner protector cardboard 20 from the temporary transfer trough 2121 to the final station.

[0040] In one embodiment, the first conveying assembly 311 includes two first conveying members 3112 arranged opposite to each other along a first direction. The first conveying members 3112 are slidably mounted on the first frame 32 along the first direction, and the space between the two first conveying members 3112 forms a first conveying groove 3111. The two first conveying members 3112 have conveying positions that are close to each other and passing positions that are far apart from each other. When the first conveying member 3112 is in the passing position, the material picking device 2 can drive the corner protector paper 20 to extend into the first conveying groove 3111. When the first conveying member 3112 is in the conveying position, the two first conveying members 3112 can respectively abut against the corner protector paper 20 to drive the corner protector paper 20 to move along the extension direction of the first conveying groove 3111.

[0041] In this embodiment, two first conveying members 3112 are each slidably mounted on the first frame 32 via a set of linear sliding pairs to control the movement of the first conveying members 3112 along the first direction. The gap between the two first conveying members 3112 forms the first conveying trough 3111. When the first conveying members 3112 are in the passing position, the distance between them is increased to exceed the width of the corner protector cardboard 20. At this time, the inlet width of the first conveying trough 3111 is large enough that the picking device 2 can vertically or horizontally extend the corner protector cardboard 20 into and place it in the trough space between the two first conveying members 3112 without interfering with the conveying members. After the corner protector cardboard 20 is placed, the two first conveying members 3112 move towards each other along the first direction until they reach the preset conveying position. At this time, the inner working surfaces of the two first conveying members 3112 are in close contact with or maintain slight pressure contact with the two sides of the corner protector cardboard 20. The first conveying component 3112 can be composed of a friction wheel, synchronous belt, or small roller assembly driven by a motor. Its working surface contacts the side of the corner protector cardboard 20, and synchronously drives the corner protector cardboard 20 to move along the extension direction of the first conveying trough 3111 through friction. The first conveying assembly 311 can accommodate corner protector cardboard 20 of different sizes and specifications, and can ensure the positioning accuracy and conveying stability of the cardboard during the transfer process.

[0042] In one embodiment, the second conveying assembly 312 includes a rotating disk 3122 rotatably connected to the first frame 32, and two second conveying members 3123 mounted on the rotating disk 3122. The two second conveying members 3123 are arranged opposite to each other along a first direction, and the space between the two second conveying members 3123 forms a second conveying groove 3121. The two second conveying members 3123 can respectively abut against the corner protector cardboard 20 to drive the corner protector cardboard 20 to move along the extension direction of the second conveying groove 3121.

[0043] In this embodiment, the rotating disk 3122 is connected to the corresponding mounting base of the first frame 32. The two second conveying components 3123 are mounted on the upper surface of the rotating disk 3122 through their respective mounting brackets 2131. The two second conveying components 3123 are arranged opposite to each other along the first direction, and the space between them constitutes the second conveying groove 3121. The width of the second conveying groove 3121 matches the corner protector cardboard 20. Each second conveyor 3123 can be a synchronous belt driven by a micro motor, a friction wheel, or a series of small rollers, with the running surface of the driving element facing the inside of the conveying trough. When the corner protector cardboard 20 is fed from the first conveying assembly 311 into the initial section of the second conveying trough 3121, the two second conveyors 3123 start synchronously. Through the friction with the two sides of the corner protector cardboard 20, they jointly clamp and drive the corner protector cardboard 20 to move along the extension direction of the second conveying trough 3121. The operator can adjust the extension direction of the second conveying trough 3121 according to actual needs through the rotating disk 3122, so that the corner protector cardboard 20 is moved to the preset station. Thus, the second conveying assembly 312 can not only achieve linear conveying, but also adjust the discharge angle of the corner protector cardboard 20 during the conveying process or at the beginning stage of the conveying, so as to accurately move the corner protector cardboard 20 to the preset position in different orientations in the wrapping device, thereby improving the flexibility of the paper sheet machine 100 and its adaptability to different packaging processes.

[0044] In one embodiment, the conveying device 3 includes two sets of conveying modules 31, each consisting of an upper conveying module 31a and a lower conveying module 31b spaced apart in a vertical direction. The upper conveying module 31a is vertically mounted on the first frame 32. The upper conveying module 31a can move vertically within a preset height range in a third direction; the lower conveying module 31b is typically mounted at a fixed height at a lower position on the first frame 32. This arrangement allows the conveying device 3 to simultaneously output two corner protectors 20, improving packaging efficiency. Furthermore, the height of the upper corner protectors 20 can be adjusted according to the actual product height, thus adapting the spacing between the upper and lower corner protectors 20 to the product height, thereby optimizing the space utilization of the production layout and the flexibility of process connections.

[0045] In one embodiment, the storage device 1 includes two sets of storage modules 11, each set including an upper storage module 11a and a lower storage module 11b spaced apart in the vertical direction; the material handling device 2 includes two sets of material handling modules 21, each set including an upper material handling module 21a and a lower material handling module 21b spaced apart in the vertical direction; the upper material handling module 21a is correspondingly arranged with the upper storage module 11a and is used to pick up the material from the upper storage module 11a. The corner protector cardboard 20 is conveyed by the group 11a; the upper conveying module 31a is correspondingly set with the upper picking module 21a and is used to transfer the corner protector cardboard 20 in the upper picking module 21a; the lower picking module 21b is correspondingly set with the lower storage module 11b and is used to pick up the corner protector cardboard 20 conveyed by the lower storage module 11b; the lower conveying module 31b is correspondingly set with the lower picking module 21b and is used to transfer the corner protector cardboard 20 in the lower picking module 21b. In this embodiment, the material storage device 1 and the material handling device 2 of the paper sheet machine 100 both adopt a double-layer modular spatial layout design to improve its material handling capacity and flexibility. This double-layer parallel structure enables the paper sheet machine 100 to output two corner protector paper sheets 20 at the same time, or to achieve uninterrupted continuous material supply through alternating work, which greatly improves the overall efficiency and production capacity of the equipment. The timing and position of the actions of all modules are synchronized and coordinated by the central control system through sensor signals to ensure that the upper and lower operation flows are independent and do not interfere with each other.

[0046] In one embodiment, the material handling device 2 further includes a second frame 22, and the material handling module 21 further includes a drive mechanism 213, which is disposed on the second frame 22. The drive mechanism 213 includes a bracket 2131 and a translation drive assembly 2132 disposed on the bracket 2131. The material handling mechanism 211 is connected to the translation drive assembly 2132, which drives the material handling mechanism 211 to perform translational movement along a first direction. The receiving member 212 is connected to the bracket 2131 and is located below the material handling mechanism 211 along a second direction, with a transition groove. 2121 extends along a third direction and is disposed on receiving member 212. Transition groove 2121 has inlet and outlet. Inlet is located at the top of transition groove 2121 and is used to receive material released by material receiving mechanism 211. Outlet is located at one end of transition groove 2121 along a third direction and is used to allow corner protector cardboard 20 to extend from the end near conveying device 3 so that conveying device 3 can move corner protector cardboard 20 out of transition groove 2121 along a second direction through the end of corner protector cardboard 20 near conveying device 3. The first direction, second direction and third direction are perpendicular to each other.

[0047] In this embodiment, the second frame 22 serves as its main support structure, providing a stable mounting foundation and positioning reference for all components installed on it. The drive mechanism 213 is integrally mounted on the second frame 22. The drive mechanism 213 includes a bracket 2131 and a translation drive assembly 2132. The translation drive assembly 2132 can be composed of a servo motor, a ball screw pair, and a precision linear guide. The material handling mechanism 211 can be a vacuum suction cup or a mechanical gripper. The material handling mechanism 211 is mounted on the mounting plate and can drive the entire material handling mechanism 211 to perform reciprocating linear translational motion along a first direction, realizing its gripping and placing action stroke. The receiving part 212 is connected to the bracket 2131 of the drive mechanism 213 by bolts or welding and is located directly below the material handling mechanism 211. The transition groove 2121 is machined or formed on the receiving part 212 and extends through it along a third direction. The top of the transition trough 2121 has a feed inlet with its opening facing upwards, used to directly receive corner protector cardboard 20 released and falling or placed from above by the material handling mechanism 211. The transition trough 2121 also has a discharge inlet at one end along a third direction, with its opening direction aligned with the second direction. This allows the end of the corner protector cardboard 20 placed in the transition trough 2121, near the conveying device 3, to extend out of the discharge inlet. This enables the subsequent conveying device 3 to clamp the extended portion and horizontally move the corner protector cardboard 20 out of the transition trough 2121 along the second direction, thus completing the material transfer.

[0048] In one embodiment, the material handling mechanism 211 includes a lifting power component and a material handling assembly. The lifting power component is driven to the material handling assembly and is used to drive the material handling assembly to move up and down along a second direction. The material handling assembly includes multiple vacuum suction cups spaced apart along a third direction. The lifting power component is rigidly driven to the material handling assembly through its output shaft or connector, and is used to drive the entire material handling assembly connected to it to move. The material handling assembly is equipped with multiple independent vacuum suction cups at equal or unequal intervals along a third direction. Each vacuum suction cup is connected to a central vacuum generator or vacuum pump system through an independent air pipe and is equipped with an independent vacuum switch valve and vacuum degree sensor. The vacuum suction cups can adhere to the surface of the cardboard under negative pressure. The spaced arrangement of multiple suction cups along a third direction ensures that the adsorption force is evenly distributed for long strips or large-area corner protectors 20, effectively preventing the cardboard from bending, slipping, or falling off during the transfer process.

[0049] In one embodiment, the storage device 1 further includes a support frame, and the storage module 11 is mounted on the support frame. The storage module 11 includes a storage bin and a feeding drive assembly. The storage bin is used to store multiple corner protector cardboard pieces 20 arranged along a first direction. The storage bin has an output port on the side of the storage bin near the picking device 2 along the first direction for the corner protector cardboard pieces 20 to pass through. The feeding drive assembly is used to drive the multiple corner protector cardboard pieces 20 to move along the first direction to push the multiple corner protector cardboard pieces 20 toward the output port. And / or, the storage device 1 further includes a separating assembly, which is provided corresponding to the storage bin. The separating assembly is used to separate the outermost corner protector cardboard piece 20 from the corner protector cardboard piece 20 behind it when the picking device 2 picks up the outermost corner protector cardboard piece 20 in the storage bin.

[0050] In this embodiment, each storage module 11 is specifically used for a storage bin that physically contains materials and a feeding drive assembly. The storage bin is configured as a long, narrow channel structure, in which multiple corner protector cardboard sheets 20 are stacked and arranged along a first direction. The storage bin has an opening on the side near the picking device 2 along the first direction, which is an output port for a single corner protector cardboard sheet 20 to pass through. The feeding drive assembly is installed at the rear end of the storage bin and can be a synchronous belt pusher mechanism driven by a servo motor or a pusher directly driven by a cylinder. The output end of the feeding drive assembly contacts the end of the paper stack, thereby continuously or intermittently applying a pushing force along the first direction towards the output port to the paper stack, thereby smoothly pushing the entire stack of corner protector cardboard sheets 20 as a whole towards the output port to compensate for the gap caused by the removal of the foremost cardboard sheet, ensuring that the outermost cardboard sheet is always in the preset ready-to-be-picked position. The material separation component is set in the output area of ​​the storage bin. When the picking device 2 performs the picking action and tries to pick up the corner protector cardboard 20 at the front end of the storage bin, it overcomes the electrostatic adsorption or vacuum adhesion between the cardboard sheets, ensuring that only the outermost single cardboard sheet is reliably picked up each time, while the subsequent cardboard sheets are blocked and kept in the storage bin, thus achieving precise single-sheet separation.

[0051] The present invention also proposes a packaging production line 200, which includes a paper sheeter 100. The specific structure of the paper sheeter 100 is as described in the above embodiments. Since the packaging production line 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0052] Referring to Figures 4 to 12, in one embodiment, the storage device 1 of the paper sheet machine 100 includes a support frame 12, a storage module 11, and a separation module (not shown). The storage module 11 is disposed on the support frame 12 and includes a storage bin 112 and a feeding drive assembly. The storage bin 112 is used to store multiple pieces of corner protector paperboard 20 stacked along a first direction. The feeding drive assembly is used to drive the multiple pieces of corner protector paperboard 20 to move along the first direction, so as to push the multiple pieces of corner protector paperboard 20 towards the output port of the storage bin 112. After a corner protector cardboard piece 20 is picked up from the output port of the storage bin 112, the separation module is used to limit the remaining corner protector cardboard pieces 20 within the storage bin 112. The separation module includes a first separation component and a second separation component. The first separation component is located above the storage bin 112 and is used to flexibly abut against the multiple corner protector cardboard pieces 20 from top to bottom. The second separation component is located at the output port of the storage bin 112 and is used to flexibly abut against the corner protector cardboard piece 20 located at the output port of the storage bin 112 along a first direction.

[0053] In this embodiment, the first direction can be the front-back direction, and the second direction can be the left-right direction. The storage bin 112 of the storage module 11 extends along the second direction. Multiple corner protector cardboard pieces 20 are stacked along the first direction and then vertically placed into the storage bin 112. The feeding drive component is located on the side of the storage bin 112 away from the output port. The feeding drive component may include a servo drive component. The servo drive component may include a pusher plate that can reciprocate along the first direction. When the corner protector cardboard piece 20 located at the output port end is picked up, the pusher plate pushes the corner protector cardboard pieces 20 stacked along the first direction to move towards the output port along the first direction, pushing the corner protector cardboard piece 20 to the output port position to replenish the corner protector cardboard piece 20.

[0054] It is understandable that, since multiple corner protector cardboard pieces 20 are stacked along the first direction, when picking up the corner protector cardboard piece 20 at the output port, the corner protector cardboard piece 20 closest to or located at the output port may be picked up simultaneously due to adhesion and adsorption. This results in an uncertain number of corner protector cardboard pieces 20 picked up at one time, possibly multiple pieces, or the corner protector cardboard pieces 20 behind may fall off under the suction and traction, leading to material waste.

[0055] To this end, the storage module 11 includes a separation module, which includes a first separation component and a second separation component. The first separation component, located above the storage bin 112, flexibly abuts against multiple corner protector cardboard pieces 20 from top to bottom, so that the multiple corner protector cardboard pieces 20 are limited vertically by the storage bin 112 and the first separation component. The second separation component, located at the output port of the storage bin 112, flexibly abuts against the corner protector cardboard pieces 20 located at the output port along a first direction towards the feeding drive component, so that the multiple corner protector cardboard pieces 20 are limited vertically by the second separation component and the feeding drive component along the first direction, ensuring that the multiple corner protector cardboard pieces 20 are stably limited when they are not discharged through the output port. Furthermore, since the first separating component flexibly abuts against the multiple corner protector cardboard pieces 20 from top to bottom, and the second separating component flexibly abuts against the corner protector cardboard pieces 20 located at the output port, when a single corner protector cardboard piece 20 is picked up at the output port, the flexible abutment generates appropriate resistance, ensuring that the cardboard pieces behind are not pulled from the output port by the cardboard pieces picked up in front. At the same time, the resistance generated by the flexible abutment is small, so when the cardboard pieces are picked up and moved out of the output port, they will not rub against the separating module and be damaged. Meanwhile, when the feeding drive component pushes the multiple corner protector cardboard pieces 20 toward the output port of the storage bin 112 to replenish the material, the friction between the multiple corner protector cardboard pieces 20 and the separating module is small, so the corner protector cardboard pieces 20 will not be damaged.

[0056] The first separation module may include a first dispensing brush 1131, which flexibly abuts against multiple corner protector cardboard pieces 20 from top to bottom. The second separation module may include a second dispensing brush 1132, which flexibly abuts against the corner protector cardboard pieces 20 located at the output port from front to back. The second separation module may be located below the first separation module, and the second dispensing brush 1132 may extend from bottom to top. There are multiple ways to pick up a single corner protector cardboard piece 20 from the output port of the storage bin 112. It can be done by adsorbing the corner protector cardboard piece 20 with a suction cup or by gripping the corner protector cardboard piece 20 with a claw. The specific method is not limited.

[0057] Optionally, the first separation component includes a first mounting plate and a first flexible member disposed below the first mounting plate. The first mounting plate extends along a first direction, and the first flexible member is arranged on the first mounting plate along the first direction. The first flexible member is used to flexibly abut against multiple pieces of corner protector cardboard 20 from top to bottom. The flexible component can be the bristles of the first separating brush 1131, which are arranged along the first direction and extend in the vertical direction. It is understood that since multiple corner protector cardboard pieces 20 are stacked along the first direction, if the multiple limiting components are limited only by the second separating component and the feeding drive component along the first direction, the multiple corner protector cardboard pieces 20 may not be sufficiently limited, resulting in a loose stack. Therefore, the first mounting plate is set to extend along the first direction, so that the first mounting plate can cover the multiple corner protector cardboard pieces 20, thereby allowing the first flexible component located below the first mounting plate to flexibly abut against the multiple corner protector cardboard pieces 20 from top to bottom. This ensures that the multiple corner protector cardboard pieces 20 can be limited by the first flexible component and the storage bin 112 in the vertical direction, ensuring that the multiple corner protector cardboard pieces 20 can maintain a stacked state and preventing the multiple corner protector cardboard pieces 20 from becoming loose, which would make it difficult to pick up the corner protector cardboard pieces 20 from the output end.

[0058] Optionally, the first flexible component includes a first flexible segment and a second flexible segment. The second flexible segment extends from the first flexible segment to the output port of the storage bin 112. The first flexible segment is used to flexibly abut against the upper part of the multiple corner protector cardboard sheets 20 from top to bottom, and the second flexible segment is used to flexibly abut against the corner protector cardboard sheets 20 located at the output end along the first direction. It is understood that if the second separating component extends from bottom to top and flexibly abuts against the corner protector cardboard sheets 20 located at the output port, it will result in greater discharge resistance of the corner protector cardboard sheets 20 at the output port, affecting the picking up of the corner protector cardboard sheets 20. If the second separating component only flexibly abuts against the lower end of the corner protector cardboard sheets 20 at the output port, it will result in a lack of flexible restraint on the upper side of the output port for the corner protector cardboard sheets 20, causing the upper part of the rear corner protector cardboard sheets 20 to be easily pulled and displaced by the front corner protector cardboard sheets 20 that have been picked up. To this end, the first flexible component is provided, including a first flexible segment and a second flexible segment, such that the second flexible segment extends from the first flexible segment to the output port of the storage bin 112. When the first flexible component extends from top to bottom, the second flexible segment can abut against the upper side of the corner protector cardboard 20, while the second separation component can abut against the lower side of the corner protector cardboard 20, so that there is a gap between the second flexible segment and the second separation component. The corner protector cardboard 20 located at the output port of the storage bin 112 can be picked up through this gap, ensuring that the picking resistance of the corner protector cardboard 20 is small, while ensuring the flexible limit of the rear corner protector cardboard 20.

[0059] Optionally, the first separation assembly further includes a mounting frame, on which a first mounting plate is movably mounted vertically, allowing the distance between the first flexible element and the first mounting plate to be adjustable. This configuration allows the distance between the first flexible element and the bottom wall of the storage bin 112 to be adjustable, enabling the storage module 11 to accommodate the storage and placement of corner protectors 20 at different heights. The first separation assembly may also include an adjusting screw, rotatably mounted above the first mounting plate and threadedly connected to the mounting frame. Rotating the adjusting screw allows for vertical adjustment of the first mounting plate, thereby adjusting the vertical position of the first flexible element.

[0060] Optionally, a second separation component is disposed below the first separation component. The second separation component includes a second flexible member extending from bottom to top, which flexibly abuts against the lower end of the corner protector cardboard 20 along a first direction. The second separation component may further include a second mounting plate, with the second flexible member disposed on the second mounting plate and extending upwards from the second mounting plate to the lower side of the output port of the storage hopper 112. This allows the second flexible member to flexibly abut against the lower side of the corner protector cardboard 20, while the second flexible segment of the first flexible member can flexibly abut against the upper side of the corner protector cardboard 20. This ensures that the corner protector cardboard 20 is stably limited when picked up, and a clearance can be reserved between the second flexible segment and the second flexible member for the suction cup or gripper to pick up the cardboard from the output port.

[0061] Optionally, the first separation component is provided in multiple sets, and the multiple sets of the first separation component are arranged at intervals along the second direction. Since the single corner protector cardboard 20 extends along the second direction, when multiple sets of the first separation component are arranged at intervals along the second direction, the multiple sets of the first separation component can flexibly abut against multiple parts of the multiple corner protector cardboard 20 along the second direction from top to bottom, ensuring that the limiting resistance of each part of the corner protector cardboard 20 along the second direction is approximately equal, thereby ensuring that after the cardboard at the output position is picked up, the multiple cardboard pieces behind it will not shift or deform.

[0062] Optionally, multiple sets of second separation components are provided, and these multiple sets of second separation components are spaced apart along the second direction at the output port of the storage bin 112. It is understood that when a single piece of corner protector cardboard 20 extends along the second direction, and multiple sets of second separation components are provided and spaced apart along the second direction, the limiting resistance experienced by the corner protector cardboard 20 along the second direction is approximately equal when picking up the single piece of corner protector cardboard 20 at the output port, facilitating the uniform application of picking force to the corner protector cardboard 20. Furthermore, limiting resistance can be uniformly applied to the rear corner protector cardboard 20 along the second direction to ensure that the rear corner protector cardboard 20 is uniformly limited at all points.

[0063] Optionally, the first separation component and / or the second separation component are configured as a dispensing brush. In this way, the bristles of the dispensing brush can flexibly abut against the corner protector 20, generating appropriate limiting resistance to prevent the rear corner protector 20 from being pulled off by the front corner protector 20, while also preventing damage to the corner protector 20. The separation module also includes a limiting component located at the output port of the storage bin 112. When the feeding drive component pushes multiple corner protector 20 pieces towards the output port of the storage bin 112, the limiting component rigidly abuts against the corner protector 20 along a first direction to limit the corner protector 20 from moving out of the storage bin 112.

[0064] It is understandable that at the output port of the storage bin 112, if only the first and second flexible members flexibly abut against the upper and lower sides of the corner protector cardboard 20, when the feeding drive assembly moves multiple corner protector cardboard 20 pieces toward the output port, there may be a situation where the driving force is too large and the limiting resistance of the first and second flexible members is insufficient. Therefore, a limiting component is also provided at the output port of the storage bin 112. This limiting component rigidly abuts against the corner protector cardboard 20 along the first direction. When the feeding drive assembly moves multiple corner protector cardboard 20 pieces toward the output port, the limiting component rigidly abuts against the corner protector cardboard 20 along the first direction to restrict the corner protector cardboard 20 from moving out. The limiting component may include a limiting cylinder and a limiting rod. The limiting cylinder drives the limiting rod to move up and down. When the limiting rod extends upward, the corner protector cardboard 20 located at the output port of the storage bin 112 can abut against the limiting rod. When the corner protector cardboard 20 is picked up from the output port of the storage bin 112, the limiting cylinder can drive the limiting rod to move downward, so as not to rigidly abut against the corner protector cardboard 20, thus ensuring the material discharge operation of the storage device 1. After the corner protector cardboard 20 material in the storage module 11 has been discharged, in order to facilitate the replenishment of material to the storage module 11, the storage device 1 may optionally include a hopper drive assembly. The hopper drive assembly is connected to the storage module 11 and is used to drive the storage module 11 to reciprocate along the second direction. After the multiple corner protector cardboard 20 pieces in the storage hopper 112 have been discharged, the hopper drive assembly is used to drive the storage module 11 to move out of the support frame 12 along the second direction so that the storage hopper 112 can be replenished with corner protector cardboard 20.

[0065] Optionally, the first separation component can be fixed on the support frame 12, the storage module 11 can be movably mounted on the support frame 12 along the second direction, and the second separation component and the limiting component can be disposed on the storage module 11 and move back and forth along the second direction with the storage module 11. After the multiple corner protector cardboard pieces 20 in the storage bin 112 are picked up in sequence, the storage module 11 can be moved along the second direction and removed from the support frame 12 by the bin drive component. The operator can put the multiple corner protector cardboard pieces 20 stacked along the first direction into the storage bin 112 from top to bottom. The multiple corner protector cardboard pieces 20 are limited and squeezed in the storage bin 112 by the push plate of the feeding drive component, the limiting rod of the limiting component, and the second flexible part of the second separation component. Then, the storage module 11 is driven back to its original position by the bin drive component. At this time, the first flexible part of the first separation component flexibly abuts against the multiple corner protector cardboard pieces 20 and cooperates with the bottom wall of the storage bin 112 to limit the multiple corner protector cardboard pieces 20 to the upper and lower positions.

[0066] Optionally, the hopper drive assembly is provided in two sets, and the two sets of hopper drive assemblies are respectively located on both sides of the storage hopper 112 along the second direction. Each set of hopper drive assemblies includes a hopper drive component and a guide component. The storage hopper 112 is movably connected to the support frame 12 along the first direction through the guide component, and the hopper drive component drives the connection between the storage hopper 112 and the support frame 12.

[0067] It is understandable that when the storage module 11 is equipped with two sets of hopper drive components, and the two sets of hopper drive components are respectively located on both sides of the storage hopper 112 along the second direction, it can ensure that the storage module 11 is subjected to balanced forces when sliding along the second direction, and will not jam. The guide component can be mounted on the support frame 12, and the storage module 11 can be slidably mounted on the guide component. The guide component can be a ball linear guide roller or a guide chain. The hopper drive component can be a cylinder or a hydraulic cylinder; no specific limitation is made here.

[0068] Optionally, the storage modules 11 are arranged in two groups, with the two groups of storage modules 11 spaced apart in the vertical direction. Each group of storage modules 11 may be equipped with a corresponding set of hopper drive components, or the two groups of storage modules 11 may be driven by the same set of hopper drive components, which is not limited here.

[0069] Optionally, the storage device 1 can be used in the paper sheet machine 100. The paper sheet machine 100 may include the storage device 1, a feeding mechanism, and a conveying device 3. The feeding mechanism picks up corner protector paper sheets 20 from the storage device 1 using a suction cup. After picking up a single corner protector paper sheet 20 from the storage bin 112 of the storage module 11, the feeding mechanism conveys it to the conveying device 3. The conveying device 3 conveys the corner protector paper sheet 20 to the packaging machine at a certain angle. The packaging machine wraps the corner protector paper sheet 20 around the upper and lower ends of the fabric roll, protecting the two angular ends of the fabric roll and preventing damage. Therefore, in this embodiment, the storage module 11 is configured as two sets, spaced apart vertically, so that the subsequent conveying device 3 can simultaneously convey two sets of vertically spaced corner protector paper sheets 20 to the packaging machine. The corner protector cardboard 20 may include serrated segments and a body segment. When the corner protector cardboard 20 is stacked in the storage bin 112 along the first direction, the serrated segments of the corner protector cardboard 20 located in the upper storage module 11 face upwards, and the serrated segments of the corner protector cardboard 20 located in the lower storage module 11 face downwards. When the corner protector cardboard 20 is bent into a roll, the serrated segments of the corner protector cardboard 20 can be folded. Therefore, when the subsequent packaging machine wraps the corner protector cardboard 20 around both ends of the roll, the serrated segments of the two sets of corner protector cardboard 20 can respectively wrap the upper and lower end faces of the roll, and the body segment of the corner protector cardboard 20 wraps around the periphery of the roll, forming a wrapping around both ends of the roll.

[0070] Optionally, the material handling device 2 includes a frame and at least one set of material handling modules 21 disposed on the frame. The material handling module 21 includes a drive mechanism 213, a material handling mechanism 211 and a receiving component 212. The drive mechanism 213 is mounted on the frame and includes a support 2131 and a translation drive assembly 2132 mounted on the support 2131. The material picking mechanism 211 is connected to the translation drive assembly 2132, which drives the material picking mechanism 211 to move in a first direction. The material picking mechanism 211 is used to pick up or release materials. The receiving member 212 is connected to the support 2131 and is located below the material picking mechanism 211 in a third direction. The receiving member 212 has a transition groove 2121 extending in a second direction. The transition groove 2121 has an inlet and an outlet. The inlet is located at the top of the transition groove 2121 and is used to pick up materials released by the material picking mechanism 211. The outlet is located at one end of the transition groove 2121 in the second direction and is used to output the materials in the transition groove 2121 in the third direction. The first direction, the third direction, and the second direction are perpendicular to each other.

[0071] The material handling device 2 can be used in a paper sheeter 100, which may include a material handling device 2, a storage device 1, and a feeding device. The material handling device 2 is used to pick up the material (e.g., corner protector cardboard 20) stored in the storage device 1 and then convey the material to the feeding device. Of course, the material handling device 2 can also be used to pick up other materials with similar structures. The paper sheeter 100 can be applied to a packaging production line, which may include a paper sheeter 100 and a film winding machine. The film winding machine is used to perform film winding operations on the outer periphery of roll products (e.g., non-woven fabric rolls). The paper sheeter 100 is used to feed the corner protector cardboard 20 to the film winding machine and, during the film winding process, uses the film winding machine to wind the corner protector cardboard 20 around the axial corners of the roll product to protect the corners of the roll product.

[0072] To facilitate the winding of the corner protector 20 onto the end corners of the roll product, the corner protector 20 may include a strip-shaped paper body and a serrated portion on one side of the paper body in the width direction. The serrated portion has multiple notches spaced apart along the length direction of the paper body, so that serrations are formed between adjacent notches. One end of the corner protector 20 can be fed into the angle between the end of the roll product and the stretch film by the feeding device of the paper sheet machine 100. When the corner protector 20 enters the winding position, the paper body adheres to the outer peripheral surface of the roll product, and the serrated portion extends beyond the end face of the roll product. Under the tension of the stretch film, it is pressed against the end face of the material, so that the serrated portion of the corner protector 20 can automatically fold into a right angle relative to the paper body, thereby protecting the end corners of the roll product.

[0073] The material handling device 2 includes a frame and material handling modules 21 mounted on the frame. The number of material handling modules 21 can be set according to actual needs, and can be one, two, or more. For example, when applied to a packaging production line for roll products, since both ends of the roll product need to be wound with corner protectors 20, the material handling device 2 can include two sets of material handling modules 21 spaced apart along the height direction of the frame. The lower material handling module 21b is used to pick up the lower corner protectors 20 and convey them to the lower end of the roll product for winding through a feeding device. The upper material handling module 21a is used to pick up the upper corner protectors 20 and convey them to the upper end of the roll product for winding through a feeding device. The feeding device can receive the corner protectors 20 conveyed by the material handling modules 21 through a belt conveyor mechanism and convey them to the film winding machine.

[0074] The following describes the specific structure of one set of material handling modules 21. When there are multiple sets of material handling modules 21, the structures of each material handling module 21 are the same or similar.

[0075] In this embodiment, the first direction can be the width direction of the material picking module 21 (e.g., the front-to-back direction), the third direction can be the height direction of the material picking module 21 (e.g., the up-down direction), and the second direction can be the length direction of the material picking module 21 (e.g., the left-to-right direction).

[0076] The material handling module 21 includes a drive mechanism 213, a material handling mechanism 211, and a receiving component 212. The drive mechanism 213 drives the material handling mechanism 211 to move relative to the frame, enabling it to move to a suitable position to pick up the corner protectors 20. For example, in the paper machine 100, the material handling device 2 and the storage device 1 are arranged side-by-side along a first direction. The drive mechanism 213 includes a translation drive module driven by the material handling mechanism 211. This translation drive module drives the material handling mechanism 211 to move along the first direction, enabling it to pick up the corner protectors 20 from the storage device 1. The translation drive module includes, but is not limited to, cylinders, hydraulic cylinders, linear motors, electric push rods, or other modules capable of linear drive. The receiving component 212 is located below the picking module 21. The receiving component 212 has a transition groove 2121, with a feed inlet at the top. This allows the picking module 21 to release the corner protector cardboard 20 from top to bottom into the transition groove 2121 via the feed inlet. It is understood that the corner protector cardboard 20 is typically elongated. To ensure the corner protector cardboard 20 can be stably contained within the transition groove 2121, the receiving component 212 and the transition groove 2121 can be configured as elongated strips aligned with the extending direction of the corner protector cardboard 20. One end of the transition groove 2121 along its length is also provided with a discharge inlet, which can connect with the feeding device. Understandably, the width of the transition groove 2121 should not be too large, usually slightly larger than the thickness of the corner protector paperboard 20. This ensures that the corner protector paperboard 20 remains perpendicular to the bottom wall of the transition groove 2121 within the transition groove 2121. In other words, the transition groove 2121 can position the corner protector paperboard 20 so that it can continue to be conveyed to the downstream feeding device.

[0077] For example, the feeding device can use a belt conveyor mechanism for feeding. The belt conveyor mechanism includes two conveyor belts arranged opposite each other, forming a clamping groove between the two conveyor belts for accommodating the corner protector cardboard 20. The feeding port of the clamping groove can connect with the discharge port of the transition groove 2121. When the picking module 21 releases the corner protector cardboard 20 into the transition groove 2121, the end of the corner protector cardboard 20 can also fall into the clamping groove of the belt conveyor mechanism. Then, the belt conveyor mechanism transports the corner protector cardboard 20 to the downstream station. As the belt conveyor mechanism drives the corner protector cardboard 20 to move, the corner protector cardboard 20 in the transition groove 2121 can move towards the belt conveyor mechanism through the discharge port. In this way, the receiving component 212 can realize the buffering and positioning of the corner protector cardboard 20, so as to achieve accurate delivery of the corner protector cardboard 20 to the feeding device.

[0078] At least one set of material picking modules 21 is provided on the frame. Each material picking module 21 includes a drive mechanism 213, a material picking mechanism 211, and a receiving component 212. When applied to the paper sheet machine 100, the translation drive assembly 2132 of the drive mechanism 213 drives the material picking mechanism 211 to extend along a first direction to the material picking position to pick up material (e.g., corner protector cardboard 20), and then retracts back to its original position along the first direction. The material picking mechanism 211 releases the picked-up corner protector cardboard 20 so that it can fall into the transition groove 2121 for buffering through the feed slot at the top of the receiving component 212. The discharge slot of the transition groove 2121 can be used for precise docking with the feed port of the feeding device. At the same time, the transition groove 2121 can position the corner protector cardboard 20 to ensure that it does not tilt, thereby facilitating the smooth transfer of the corner protector cardboard 20 from the transition groove 2121 through the discharge slot to the feeding device. The above technical solution can achieve buffering and positioning of corner protector cardboard 20, and achieve precise delivery of corner protector cardboard 20.

[0079] In order to enable the material picking mechanism 211 to pick up materials at different heights more accurately, the drive mechanism 213 may optionally include a lifting drive assembly 2133 mounted on the frame. The lifting drive assembly 2133 is driven to connect with the support 2131 and is used to drive the support 2131 to move up and down relative to the frame in a third direction.

[0080] Optionally, the lifting drive assembly 2133 is driven to connect with the bracket 2131. The lifting drive assembly 2133 drives the bracket 2131 to move up and down, which in turn drives the translation drive assembly 2132, the material picking mechanism 211, and the receiving component 212 to move up and down as a whole. Thus, even if the position of the material picking mechanism 211 changes along a third direction, the receiving component 212 remains below the material picking mechanism 211, allowing the material picking mechanism 211 to easily release the material into the transition groove 2121 of the receiving component 212 after picking it up, thereby improving material transfer efficiency. The lifting drive assembly 2133 may include, but is not limited to, mechanisms using cylinders, hydraulic cylinders, electric push rods, servo motors, and ball screws to achieve the lifting drive.

[0081] For example, the frame is provided with two sets of material handling modules 21 spaced apart along its height direction (i.e., the third direction), namely an upper material handling module 21a and a lower material handling module 21b. Both the upper drive module and the lower material handling module 21b include a lifting drive assembly 2133. The lifting drive assembly 2133 of the upper material handling module 21a can use a servo motor and ball screw mechanism to drive the material handling mechanism 211 to perform lifting movements, thus giving the upper material handling mechanism 211 a large stroke and high motion accuracy. The lifting drive assembly 2133 of the lower material handling module 21b can use a cylinder to drive the material handling mechanism 211 to perform lifting movements, resulting in a simpler structure, smaller footprint, and lower cost.

[0082] To ensure the stability of the material handling mechanism 211's translational movement along the first direction, the drive mechanism 213 may optionally include a guide assembly 2134 disposed on the support 2131. The material handling mechanism 211 is movably connected to the support 2131 via the guide assembly 2134, which guides the movement of the material handling mechanism 211 relative to the support 2131 along the first direction. The guide assembly 2134 may include, but is not limited to, linear guides or linear bearing pairs for guidance.

[0083] For example, the guide assembly 2134 includes at least one linear bearing pair, which includes a linear bearing fixed to the bracket 2131 and a guide shaft passing through the linear bearing. The guide shaft extends along a first direction, and one end of the guide shaft is connected to the material handling mechanism 211. When the translation drive module drives the material handling mechanism 211 to move relative to the bracket 2131 along the first direction, the cooperation between the linear bearing and the guide shaft can achieve guidance along the first direction, making the movement of the material handling mechanism 211 more stable and reliable. Optionally, the guide assembly 2134 includes multiple linear bearing pairs, which can further improve the movement stability of the material handling mechanism 211, and also provide a certain support for the material handling mechanism 211, ensuring the installation reliability of the material handling mechanism 211.

[0084] It is understandable that when the transition groove 2121 of the receiving component 212 is used to receive the corner protector cardboard 20, since the width of the transition groove 2121 should not be too wide, the opening width of the feed groove of the transition groove 2121 is usually also relatively narrow.

[0085] To ensure that the picking mechanism 211 can accurately release the picked-up corner protector cardboard 20 into the transition groove 2121, optionally, the picking mechanism 211 includes a lifting power component 2111 and a picking assembly 2112. The lifting power component 2111 is driven to the picking assembly 2112, and is used to drive the picking assembly 2112 to move up and down in a third direction. Thus, after the picking assembly 2112 picks up the corner protector cardboard 20, the lifting power component 2111 drives the picking assembly 2112 to move downwards a certain distance, allowing the corner protector cardboard 20 picked up by the picking assembly 2112 to be accurately inserted into the transition groove 2121 from the feed slot. Then, the picking assembly 2112 completely releases the corner protector cardboard 20. The lifting power component 2111 may include, but is not limited to, using a cylinder, hydraulic cylinder, or electric push rod to achieve the lifting drive. The material handling assembly 2112 includes, but is not limited to, using cylinder grippers, vacuum suction cups 2112a, etc. to pick up and release materials.

[0086] Typically, the corner protector cardboard 20 is elongated. To facilitate more convenient and stable pickup of the corner protector cardboard 20, the picking assembly 2112 may optionally include a plurality of vacuum suction cups 2112a spaced apart along a second direction. This second direction can be aligned with the length direction of the corner protector cardboard 20. Thus, by adsorbing the corner protector cardboard 20 with multiple vacuum suction cups 2112a, multiple adsorption points can be formed along the length of the corner protector cardboard 20, preventing bending due to its excessive length and ensuring that the corner protector cardboard 20 can be smoothly transferred into the transition groove 2121 in a flattened state. The number of vacuum suction cups 2112a can be set according to the actual length of the corner protector cardboard 20 and is not specifically limited here.

[0087] To improve material handling efficiency, the frame may optionally include two sets of material handling modules 21 spaced apart along a third direction. Each material handling module 21 can move up and down relative to the frame along the third direction. In this way, the two sets of material handling modules 21 can respectively pick up materials within different height ranges, thus improving material handling efficiency. Furthermore, the fact that each set of material handling modules 21 can move up and down relative to the frame greatly increases the material handling range along the third direction.

[0088] In this embodiment, the storage module 11 of the storage device 1 and the picking module 21 of the picking device 2 can be configured one-to-one. The storage module 11 is used to store corner protector cardboard 20. When picking is required, the storage module 11 is used to convey the corner protector cardboard 20 along the first direction toward the side closer to the picking module 21. The picking mechanism 211 of the picking module 21 moves along the first direction toward the side closer to the storage module 11 under the drive of the translation drive module. The picking mechanism 211 picks up the outermost corner protector cardboard 20 on the storage module 11 and then releases it into the transition groove 2121 of the receiving member 212, and conveys it to the downstream feeding device through the transition groove 2121. The specific structure of the picking device 2 is as described in the above embodiment. Since this paper machine 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, and will not be described in detail here.

[0089] Optionally, the storage device 1 further includes a support frame 12, and the storage module 11 includes a conveying mechanism 111 disposed on the support frame 12, and a storage bin 112 drivenly connected to the conveying mechanism 111. The storage bin 112 is used to store corner protector cardboard 20. Multiple corner protector cardboard 20 can be stacked in the storage bin 112 along the first direction. The storage bin 112 is provided with a discharge port 1121 on the side facing the material taking device 2. The conveying mechanism 111 is used to drive the storage bin 112 to reciprocate along the first direction.

[0090] In this embodiment, the support frame 12 is used to support the storage module 11. When multiple storage modules 11 are provided, they can be installed on the same support frame 12. The storage module 11 includes a conveying mechanism 111 and a storage bin 112. The conveying mechanism 111 is used to drive the storage bin 112 to reciprocate along a first direction so that the storage bin 112 can move closer to or further away from the picking module 21. Multiple corner protector cardboard pieces 20 can be stacked in the storage bin 112 along the first direction, with the paper surface of each corner protector cardboard piece 20 in an upright state. When picking is required, the conveying mechanism 111 drives the storage bin 112 to move along the first direction to the side of the support frame 12 close to the picking module 21. The picking mechanism 211 of the picking module 21 moves along the first direction to the outlet 1121 of the storage bin 112 to pick up the corner protector cardboard piece 20 at the outlet 1121. When the corner protector cardboard 20 in the storage bin 112 is used up, the conveying mechanism 111 can drive the storage bin 112 to move along the first direction to the side of the support frame 12 away from the material picking module 21, so as to facilitate the material replenishment operation on the other side of the support frame 12.

[0091] Optionally, the conveying mechanism 111 includes a cylinder and a ball screw guide rail. The storage bin 112 is slidably mounted on the support frame 12 along the first direction via the ball screw guide rail. The cylinder is driven by the storage bin 112 to drive the storage bin 112 to reciprocate along the ball screw guide rail. Of course, the conveying mechanism 111 can also use a belt pulley conveyor, a motor and gear rack mechanism, or other methods to realize the movement of the storage bin 112 along the first direction.

[0092] It is understandable that multiple corner protector cardboard pieces 20 are stacked in the storage bin 112. Since two adjacent corner protector cardboard pieces 20 are stuck together, when the material picking module 21 picks up the outermost corner protector cardboard piece 20, it may bring out the corner protector cardboard piece 20 behind it.

[0093] In order to separate two adjacent corner protector cardboard pieces 20, the storage module 11 may optionally include a material distribution component 113. The material distribution component 113 is provided corresponding to the storage bin 112. The material distribution component 113 is used to separate the outermost corner protector cardboard piece 20 from the corner protector cardboard piece 20 behind it when the material picking device 2 picks up the outermost corner protector cardboard piece 20.

[0094] For example, the material distribution assembly 113 may include a flexible material distribution component (e.g., a brush) to limit the rear corner protector 20, preventing it from being pulled out when the material picking module 21 picks up the outermost corner protector 20. Alternatively, the material distribution assembly 113 may include a movable baffle. During material picking, the baffle is inserted between the outermost corner protector 20 and its adjacent rear corner protector 20 to provide rigid limiting. After picking is complete, the baffle moves to a clearance position to allow the rear corner protector 20 to be easily removed. Of course, other forms of the material distribution assembly 113 can also be used for material distribution.

[0095] Optionally, the material distribution assembly 113 includes a first material distribution brush 1131, which is located at the lower edge of the discharge port 1121 and is used to abut against the lower edge of the corner protector cardboard 20 near the discharge port 1121; and / or, the material distribution assembly 113 includes a second material distribution brush 1132, which is located above the storage bin 112 and is used to abut against the top of the multiple corner protector cardboard 20 pieces in the storage bin 112.

[0096] For example, the material separating component 113 may include a first separating brush 1131 disposed at the lower edge of the discharge port 1121. The first separating brush 1131 abuts against the lower edge of the corner protector cardboard 20 near the discharge port 1121. Because the first separating brush 1131 has a certain degree of flexibility, only a slight force is required from the material handling module 21 to allow the outermost corner protector cardboard 20 to pass over the first separating brush 1131 and be removed. At the same time, the resetting of the separating brush will continue to limit the rear corner protector cardboard 20, preventing the rear corner protector cardboard 20 from being carried out as well. Furthermore, because the first separating brush 1131 is relatively soft, it can avoid scratching the corner protector cardboard 20 while separating the materials, ensuring that the corner protector cardboard 20 can be removed intact.

[0097] Optionally, multiple first separating brushes 1131 can be spaced apart along the second direction (i.e., the length direction of the corner protector 20). Thus, by having multiple first separating brushes 1131 act on multiple portions along the length of the corner protector 20, a better limiting effect can be achieved, ensuring effective separation of the outermost corner protector 20 from the corner protectors 20 behind it. Alternatively, a single first separating brush 1131 can be provided, extending from one end of the corner protector 20 to the other.

[0098] For example, the material distribution component 113 may include a second material distribution brush 1132 disposed above the storage bin 112, the second material distribution brush 1132 abutting against the top of multiple corner protector cardboard pieces 20 inside the storage bin 112. The second material distribution brush 1132 provides resistance to the top of the corner protector cardboard pieces 20, and because the second material distribution brush 1132 is flexible, only a slight force is required from the material handling module 21 to allow the outermost corner protector cardboard piece 20 to pass over the second material distribution brush 1132 and be removed. Simultaneously, the resetting of the material distribution brush continues to limit the movement of the rear corner protector cardboard pieces 20, preventing them from being carried out as well. Furthermore, because the second material distribution brush 1132 is relatively soft, it avoids scratching the corner protector cardboard pieces 20 while distributing the material, ensuring that the corner protector cardboard pieces 20 can be removed intact.

[0099] Optionally, the second separating brush 1132 is an elongated strip extending along the first direction, so that the second separating brush 1132 can completely cover the multiple corner protector cardboard sheets 20 in the storage bin 112, and the bristles of the second separating brush 1132 can extend between any two adjacent corner protector cardboard sheets 20. Optionally, multiple second separating brushes 1132 are provided, and the multiple second separating brushes 1132 are spaced apart along the second direction (that is, the length direction of the corner protector cardboard sheets 20). In this way, by having multiple second separating brushes 1132 act on multiple parts along the length direction of the corner protector cardboard sheets 20 respectively, a better limiting effect can be achieved, thereby ensuring that the outermost corner protector cardboard sheet 20 is effectively separated from the corner protector cardboard sheet 20 behind it.

[0100] Optionally, the material distribution assembly 113 includes a first material distribution brush 1131 and a second material distribution brush 1132. The first material distribution brush 1131 is located at the lower edge of the discharge port 1121, and the second material distribution brush 1132 is located above the storage bin 112. The first material distribution brush 1131 is used to abut against the lower edge of the corner protector cardboard 20 near the discharge port 1121, and the second material distribution brush 1132 is used to abut against the top of the multiple corner protector cardboard pieces 20 inside the storage bin 112. In this way, through the cooperation of the first material distribution brush 1131 and the second material distribution brush 1132, a more reliable flexible limiting effect can be achieved on the corner protector cardboard 20, resulting in a better material distribution effect.

[0101] Optionally, the storage device 1 includes two sets of storage modules 11, each set including an upper storage module 11a and a lower storage module 11b spaced apart in the vertical direction; the picking device 2 includes two sets of picking modules 21, each set including an upper picking module 21a and a lower picking module 21b spaced apart in the vertical direction; the upper picking module 21a is correspondingly arranged to the upper storage module 11a and is used to pick up the corner protector cardboard 20 conveyed by the upper storage module 11a; the lower picking module 21b is correspondingly arranged to the lower storage module 11b and is used to pick up the corner protector cardboard 20 conveyed by the lower storage module 11b.

[0102] Optionally, the upper material picking module 21a cooperates with the upper material storage module 11a to pick up the upper corner protector cardboard 20, and the lower material picking module 21b cooperates with the lower material storage module 11b to pick up the lower corner protector cardboard 20. The upper and lower material picking modules 21 can work simultaneously, which can effectively improve the material picking efficiency.

Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
