[0057] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a gantry-type paper unloader.

[0058] A gantry-type paper unloader includes a mounting body 1 and a mounting frame 2, the mounting frame 2 being disposed on the mounting body 1. It also includes a moving mechanism disposed within the mounting body 1 for component movement; a paper unloading mechanism disposed on the moving mechanism for moving paper stacks; the paper unloading mechanism includes a first alignment plate 3 disposed on the paper unloading mechanism for paper stack alignment; a second alignment plate 4 disposed on the paper unloading mechanism for paper stack alignment; a mounting component 5 disposed within the second alignment plate 4 and fixedly connected to it; two first cylinders 6 disposed on and fixedly connected to the mounting component 5; a first clamping plate 7 disposed at and fixedly connected to the output end of the first cylinders 6; a first motor 8 disposed within and fixedly connected to the mounting component 5; a first threaded rod 9 disposed at and fixedly connected to the output end of the first motor 8; and a second clamping plate 10 disposed on and threadedly connected to the first threaded rod 9.

[0059] With this configuration, during operation, the second moving component 15 drives the paper unloading mechanism to move along the first slide rail, bringing the rotating wheel 13 closer to the paper stack. Simultaneously, the second driving component 19 causes the rotating wheel 13 to rotate. When the rotating wheel 13 contacts the paper stack, its rotation separates the paper stack. Subsequently, the first moving component 14, equipped with the second alignment plate 4, moves the second alignment plate 4 to the paper stack position. The first cylinder 6 pushes the first clamping plate 7, while the first motor 8 drives the first threaded rod 9 to rotate, causing the second clamping plate 10 to move. As the first clamping plate 7 and the second clamping plate 10 move, the distance between them increases. The paper stack is moved until the upper part of the paper stack that can be separated from the rotating wheel 13 is clamped. Then, the first moving member 14 moves the first clamping plate 7 and the second clamping plate 10 to a position that can clamp the paper stack. Then, the first cylinder 6 drives the first clamping plate 7 to move, contact the paper and clamp it. Then, the first moving member 14, which is equipped with the second alignment plate 4, moves closer to the first alignment plate 3 and moves the paper stack to the placement plate 11. Then, the first cylinder 6 drives the first clamping plate 7 to release the paper stack and place the paper stack on the placement plate 11. The rotating wheel 13 rotates counterclockwise when it rotates.

[0060] refer to Figure 1 and Figure 2 In a preferred embodiment, the paper unloading mechanism further includes: a separation section disposed on the moving mechanism for separating paper stacks; an adjustment section disposed on the moving mechanism for adjusting the first alignment plate 3 and the second alignment plate 4; and a paper unloading section disposed on the adjustment section for unloading paper.

[0061] refer to Figure 1 In a preferred embodiment, the separation unit includes: a placement plate 11, disposed on the moving mechanism, for placing paper stacks; a first driving member 12, disposed on the placement plate 11 and fixedly connected to the placement plate 11; and a rotating wheel 13, disposed on the first driving member 12, for separating paper stacks.

[0062] refer to Figure 4 and Figure 5 In a preferred embodiment, the adjustment unit includes: two first moving members 14, which are disposed on the moving mechanism for moving the component; two mounting blocks 16, which are disposed on the first moving members 14 and fixedly connected to them; and two second cylinders 17, which are disposed within the mounting blocks 16 and fixedly connected to them.

[0063] refer to Figure 3 and Figure 4In a preferred embodiment, the adjustment unit further includes: two fixing brackets 18, which are disposed at the output end of the second cylinder 17 and fixedly connected to the output end of the second cylinder 17; and two second driving members 19, which are disposed on the fixing brackets 18 for providing power.

[0064] refer to Figure 5 In a preferred embodiment, the paper unloading unit includes: two second motors 20, which are mounted on and fixedly connected to the mounting block 16; two second threaded rods 21, which are located at the output ends of the second motors 20 and fixedly connected to them; two movable plates 22, which are mounted on the second threaded rods 21 and threadedly connected to them; and two unloading paperboards 23, which are mounted on and fixedly connected to the movable plates 22.

[0065] With this setup, during operation, the second driving component 19 on the second alignment plate 4 drives the second alignment plate 4 to rotate, ensuring that the second alignment plate 4 does not contact the paper stack when moving. Then, the first moving component 14 on the second alignment plate 4 moves to the other side of the paper stack. Subsequently, the second driving component 19 drives the second alignment plate 4 to rotate, keeping the second alignment plate 4 vertical. Then, the first moving components 14 on both sides move together to align the first alignment plate 3 and the second alignment plate 4 with the paper stack. After alignment is completed, the first moving components 14 on both sides drive the first alignment plate 3 and the second alignment plate 4 to release the paper stack. The second motor 20 then works, driving the second threaded rod 21 to rotate. The second threaded rod 21 drives the moving plate 22 to move, allowing the moving plate 22 to move the unloading plate 23, pushing the aligned paper stack away from the placement plate 11 and into the processing area. The second cylinder 17 ensures that the first alignment plate 3 and the second alignment plate 4 are in contact with the placement plate 11.

[0066] refer to Figure 2 and Figure 3 In a preferred embodiment, the moving mechanism includes: a third motor 24, mounted on and fixedly connected to the mounting frame 2; a third threaded rod 25, mounted on and fixedly connected to the output end of the third motor 24; a lifting member 26, mounted on and threadedly connected to the third threaded rod 25; a first guide rail 27, mounted on and fixedly connected to the lifting member 26; a second moving member 15, mounted on the first guide rail 27, for mounting the placement plate 11; and a second guide rail 28, mounted on the first guide rail 27, for mounting the first moving member 14.

[0067] With this configuration, during operation, the third motor 24 drives the third threaded rod 25 to rotate, causing the lifting component 26 to lift and move, and also causing the first slide rail to move, thus moving the entire paper unloading mechanism. The first slide rail is used to move the second moving component 15, and the second slide rail is used to move the two first moving components 14. Both the first moving component 14 and the second moving component 15 are provided with a drive zone.

[0068] This device, by incorporating a moving mechanism, enables the paper unloading mechanism to move and adjust flexibly to adapt to the processing needs of paper stacks of different positions and sizes. This allows the paper unloading mechanism to move freely in the horizontal direction, further enhancing its adaptability and flexibility. Through the coordinated operation of the separation section, adjustment section, and paper unloading section, the device achieves rapid separation, alignment, and unloading of paper stacks. Simultaneously, it adds the function of the second alignment plate 4, allowing it to assist the rotating wheel 13 in quickly moving the paper stack onto the placement plate 11.

[0069] In summary, this device achieves automated paper stack processing through the coordinated operation of the moving mechanism and the paper unloading mechanism, thereby improving production efficiency, reducing labor costs, and demonstrating significant economic and social benefits.

[0070] Working principle: In use, the paper stack is placed near the second alignment plate 4. Then, the third motor 24 drives the third threaded rod 25 to rotate, causing the lifting component 26 to lift and move, which in turn moves the first slide rail, thus moving the entire paper unloading mechanism to the appropriate position. The second moving component 15 then moves the paper unloading mechanism along the first slide rail, bringing the rotating wheel 13 closer to the paper stack. Simultaneously, the second driving component 19 rotates the rotating wheel 13. When the rotating wheel 13 contacts the paper stack, its rotation... After separating the paper stack, the first moving member 14, which is equipped with the second alignment plate 4, moves the second alignment plate 4 to the paper stack position. The first cylinder 6 pushes the first clamping plate 7, and at the same time, the first motor 8 drives the first threaded rod 9 to rotate, causing the second clamping plate 10 to move. As the first clamping plate 7 and the second clamping plate 10 move, the distance between them increases until they can clamp the upper part of the paper stack separated by the rotating wheel 13. Then, as the first moving member 14 moves the first clamping plate 7 and the second clamping plate 10 to a position where they can clamp the paper stack, the first cylinder 6 drives the first clamping plate 10 to move. Plate 7 moves, contacts and clamps the paper, then the first moving member 14, equipped with the second alignment plate 4, moves closer to the first alignment plate 3, moving the paper stack onto the placement plate 11. Then, the first cylinder 6 drives the first clamping plate 7 to release the paper stack, placing it on the placement plate 11. Next, the second driving member 19, equipped with the second alignment plate 4, drives the second alignment plate 4 to rotate, ensuring that the second alignment plate 4 does not contact the paper stack during movement. Then, the first moving member 14, equipped with the second alignment plate 4, moves to the other side of the paper stack, and then the second... The driving component 19 drives the second alignment plate 4 to rotate, keeping the second alignment plate 4 vertical. Then, the first moving components 14 on both sides move together to align the first alignment plate 3 and the second alignment plate 4 with the paper stack. After alignment is completed, the first moving components 14 on both sides drive the first alignment plate 3 and the second alignment plate 4 to release the paper stack. The second motor 20 then works, driving the second threaded rod 21 to rotate. The second threaded rod 21 drives the moving plate 22 to move, allowing the moving plate 22 to drive the unloading plate 23 to move, pushing the aligned paper stack away from the placement plate 11 and into the processing area.
