DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The object of the present invention is to provide a paper loading machine for realizing side loading of paper on paper processing equipment such as a paper mounting machine.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1-9 As shown, this embodiment provides a paper loading machine 100, including a paper separation device 2 having a paper stacking area 24, and a reversing paper feeding device 4 for receiving the paper output by the paper separation device 2.

[0036] The paper separation device 2 includes a paper separation workbench 21, a paper separation conveyor belt 22 and a paper separation paper stopper 23, wherein the paper separation conveyor belt 22 and the paper separation paper stopper 23 are installed on the paper separation workbench 21. The paper separation paper stopper 23 is located above the paper separation conveyor belt 22, and a paper discharge gap is provided between the paper separation paper stopper 23 and the paper separation conveyor belt 22 to allow the paper in the paper stacking area 24 to pass through, the paper stacking area 24 is located above the paper separation conveyor belt 22, and the paper separation paper stopper 23 is located on one side of the paper stacking area 24. The paper separation conveyor belt 22 has a paper separation paper discharge end 221.

[0037] The reversing paper feeding device 4 is located on the side of the paper separation stopper 23 away from the paper stacking area 24, and is used to receive the paper outputted by the paper separation paper output end 221. The reversing paper feeding device 4 includes a reversing workbench 41 and a reversing conveyor belt 42, the reversing conveyor belt 42 is installed on the reversing workbench 41 and its conveying direction is perpendicular to the conveying direction of the paper separation conveyor belt 22, and the reversing conveyor belt 42 has a reversing paper feeding end 421, and the height of the reversing paper feeding end 421 is lower than the paper separation paper output end 221.

[0038] It should be noted that the “paper feed end” and “paper discharge end” referred to in this embodiment are respectively the position where paper falls (input paper) and the position where paper discharges (output paper) on the upper belt surface of the corresponding conveyor belt.

[0039] In actual use, the paper is piled up in the paper stacking area 24. After the paper separation conveyor belt 22 is started, the lower layer of paper passes through the paper discharge gap with the paper separation conveyor belt 22, and the upper layer of paper is blocked by the paper separation stopper 23 and then falls. After the lower layer of paper is conveyed to the paper separation paper discharge end 221 by the paper separation conveyor belt 22, it falls on the reversing conveyor belt 42 under the action of its own inertia and gravity, and then the reversing conveyor belt 42 conveys the paper to the paper loading station on the side of the paper processing equipment such as the paper mounting machine. Since the paper loading machine 100 can realize a 90-degree turn to load paper, the paper separation device 2 can be set parallel to the length direction of the paper processing equipment such as the paper mounting machine, and the reversing paper feeding device 4 can be set perpendicular to the length direction of the paper processing equipment such as the paper mounting machine, thereby saving the space occupied by the equipment, and also reducing the labor cost because of the automatic paper loading method.

[0040] In this embodiment, the paper separation stopper 23 is preferably an integrated stainless steel plate, the lower part of which is bent into an arc toward the side away from the paper stacking area 24, and the upper part is a vertical plate. The arc plate structure allows the paper to be spread out better and avoids scratches on the paper.

[0041] Furthermore, the present embodiment also includes a paper feeding device 3 capable of conveying the output paper of the paper separation outlet end 221 to the reversing paper feeding device 4. The paper feeding device 3 is located between the paper separation device 2 and the reversing paper feeding device 4, and includes a paper feeding workbench 31 and a paper feeding conveyor belt 32. The paper feeding conveyor belt 32 is installed on the paper feeding workbench 31 and has the same conveying direction as the paper separation conveyor belt 22 (collinear or approximately collinear). The paper feeding conveyor belt 32 has a paper feeding feed end 327 and a paper feeding outlet end 328. The height of the paper feeding feed end 327 is lower than the paper separation outlet end 221, and the height of the paper feeding outlet end 328 is higher than the reversing paper feeding end 421. Generally, the running speed of the paper feeding conveyor belt 32 should be greater than the running speed of the paper separation conveyor belt 22, so that when the paper leaves the paper separation conveyor belt 22 and falls on the paper feeding conveyor belt 32, it is quickly separated from the paper on the paper separation conveyor belt 22, thereby reducing the overlapping area of ​​adjacent papers.

[0042] In order to meet the needs of conveying papers of different sizes, the paper conveying belt 32 in this embodiment is preferably a conveying belt with retractable length.

[0043] Specifically, in this embodiment, the paper feeding workbench 31 includes a paper feeding platform body 311, a paper feeding slide 312 and a paper feeding slide driving device 313. The paper feeding slide 312 is slidably mounted on the paper feeding platform body 311, and the paper feeding slide driving device 313 is used to drive the paper feeding slide 312 to slide back and forth along the conveying direction of the paper feeding conveyor belt 32.

[0044] In this embodiment, the paper feeding conveyor belt 32 includes a paper feeding belt body 321, a first paper feeding roller shaft 322, a second paper feeding roller shaft 323, a third paper feeding roller shaft 324, a fourth paper feeding roller shaft 325 and a paper feeding driving device 326. The first paper feeding roller shaft 322, the second paper feeding roller shaft 323 and the third paper feeding roller shaft 324 are used to tension the paper feeding belt body 321 from the inside and are distributed in a triangular shape, and the fourth paper feeding roller shaft 325 is used to tension the paper feeding belt body 321 from the outside. The second paper feeding roller shaft 323 is rotatably mounted on the paper feeding slide 312, the first paper feeding roller shaft 322 and the third paper feeding roller shaft 324 are rotatably mounted on the paper feeding workbench 31, and the fourth paper feeding roller shaft 325 is slidably and rotatably mounted on the paper feeding platform body 311 or the paper feeding slide 312. The fourth paper feeding roller shaft 325 is located below the first paper feeding roller shaft 322 and the second paper feeding roller shaft 323, and above the third paper feeding roller shaft 324. The paper feeding driving device 326 can at least drive one of the first paper feeding roller shaft 322 , the second paper feeding roller shaft 323 , the third paper feeding roller shaft 324 , and the fourth paper feeding roller shaft 325 to rotate.

[0045] When the paper feed carriage driving device 313 drives the paper feed carriage 312 to slide along the conveying direction of the paper feed conveyor belt 32, the second paper feed roller shaft 323 is driven to move synchronously. Since the upper belt surface of the paper feed belt body 321 is between the first paper feed roller shaft 322 and the second paper feed roller shaft 323, when the second paper feed roller shaft 323 moves, the length of the upper belt surface of the paper feed belt body 321 changes, thereby adapting to paper of different sizes. Since the overall length of the paper feed belt body 321 remains unchanged, the position of the fourth paper feed roller shaft 325 can be adjusted to match the position change of the second paper feed roller shaft 323. The fourth paper feed roller shaft 325 is slidably and rotatably installed on the paper feed platform body 311 or the paper feed carriage 312, so that the fourth roller shaft can both rotate with the paper feed belt body 321 and move.

[0046] In this embodiment, "sliding and rotating" refers to an installation method that can both rotate and slide relative to each other. "The fourth paper feed roller shaft 325 is slidably and rotatably installed on the paper feed platform 311 or the paper feed slide 312" includes but is not limited to the method of rotatably installing the fourth paper feed roller shaft 325 on a slider, and sliding the slider into a corresponding slide groove on the paper feed platform 311 or the paper feed slide 312. When the fourth paper feed roller shaft 325 slides into place, the slider can be fixed by a fastener.

[0047] It should be noted that the “sliding” referred to in this embodiment refers to the relative translation of the two, and is not limited to the connection method of sliding friction, but also includes the connection method of rolling friction.

[0048] In order to prevent the paper from falling to the outside of the paper feed belt body 321 when being transported on the paper feed belt body 321, in this embodiment, two paper feed vertical plates 3121 are fixed to the paper feed slide 312. The two paper feed vertical plates 3121 are arranged parallel to the conveying direction of the paper feed conveyor belt 32 and are located on the upper side of the paper feed belt body 321. The paper on the paper feed belt body 321 is transported between the two paper feed vertical plates 3121.

[0049] In order to make the paper on the reversing conveyor belt 42 more orderly in the horizontal direction (perpendicular to the conveying direction of the reversing conveyor belt 42), the paper feeding workbench 31 of this embodiment also includes a side paper pushing device. The side paper pushing device includes a side pushing cylinder 3122 and a side pushing plate 3123. The side pushing plate 3123 is fixed to the telescopic end of the side pushing cylinder 3122, and the side pushing cylinder 3122 is fixed to the paper feeding slide 312. The lower edge of the side pushing plate 3123 is higher than the reversing paper feeding end 421, and the gap between the lower edge of the side pushing plate 3123 and the reversing paper feeding end 421 is smaller than the thickness of the paper. The side pushing plate 3123 is used to push the paper on the reversing conveyor belt 42 along the conveying direction of the paper separation conveyor belt 22. The reversing workbench 41 includes a reversing paper stopper 413, which is opposite to the side pushing plate 3123 and is located on the side of the side pushing plate 3123 away from the paper separation device 2.

[0050] When in use, the side push cylinder 3122 can drive the side push plate 3123 to complete a periodic paper pushing action, so that one side of the paper on the reversing conveyor belt 42 is aligned with the reversing paper stopper 413.

[0051] The fixed position of the reversing paper baffle 413 can be flexibly selected. In order to adapt to different sizes of paper, the reversing workbench 41 in this embodiment further includes a reversing platform body 411, a reversing slide 412 and a reversing slide driving device 414. The reversing slide 412 is slidably mounted on the reversing platform body 411, and the reversing paper baffle 413 is fixed on the reversing slide 412. The reversing paper baffle 413 is arranged parallel to the side push plate 3123. The lower end of the reversing paper baffle 413 is not higher than the reversing paper feed end 421, and the reversing slide driving device 414 is used to drive the reversing slide 412 to slide along the conveying direction of the paper conveying belt 32.

[0052] When in use, the reversing slide 412 can be driven by the reversing slide driving device 414 to slide along the conveying direction of the paper conveyor belt 32, thereby adjusting the relative distance between the side push plate 3123 and the reversing paper baffle 413 to adapt to papers of different widths.

[0053] In order to prevent the paper from falling to the outside of the reversing conveyor belt 42 when falling from the paper feed conveyor belt 32 to the reversing conveyor belt 42, a reversing vertical plate 4121 is also fixed on the reversing slide 412 in this embodiment. The reversing vertical plate 4121 is located between the side push plate 3123 and the reversing paper stopper 413, and is located on the upper side of the reversing paper feed end 421. The reversing vertical plate 4121 is also perpendicular to the reversing paper stopper 413 and the side push plate 3123.

[0054] In order to meet the needs of conveying paper of different sizes, the paper separation workbench 21 in this embodiment includes a paper separation platform body 211, a paper separation slide 212 and a paper separation slide driving device 213. The paper separation stopper 23 is fixed on the paper separation slide 212, the paper separation slide 212 is slidably mounted on the paper separation platform body 211, and the paper separation slide driving device 213 is used to drive the paper separation slide 212 to slide along the conveying direction of the paper separation conveyor belt 22.

[0055] In order to stack the papers more neatly in the paper stacking area 24, a paper separation vertical plate 2121 is fixed on the paper separation slide 212 in this embodiment. The paper separation vertical plate 2121 is perpendicular to the upper part (vertical part) of the paper separation stopper board 23, thereby forming a right-angle area for better stacking of square papers.

[0056] Furthermore, in order to facilitate feeding of paper to the paper stacking area 24, the present embodiment also includes a paper feeding device 1 for feeding paper to the paper stacking area 24. The paper feeding device 1 includes a fixed bracket 11, a rotating bracket 12, a rotating bracket driving device, a sliding bracket 13 and a sliding bracket driving device 14. The rotating bracket 12 is rotatably connected to the fixed bracket 11, and the rotating bracket driving device is used to drive the rotating bracket 12 to rotate relative to the fixed bracket 11. The rotation axis of the rotating bracket 12 is parallel to the paper separation stopper board 23 (the corresponding paper loading machine 100 is referred to as an L-type paper loading machine) or perpendicular to the paper separation stopper board 23 (the corresponding paper loading machine 100 is referred to as a Z-type paper loading machine). The sliding bracket 13 is perpendicular to the rotating bracket 12 and is slidably installed on the rotating bracket 12. The sliding bracket 13 is used to carry the paper stack 16, and the sliding bracket driving device 14 is used to drive the sliding bracket 13 to slide along the rotating bracket 12.

[0057] When in use, after the paper stack 16 is moved onto the sliding bracket 13, the rotating bracket 12 is driven to rotate by the rotating bracket driving device, and the lower end of the rotating bracket 12 swings toward the side away from the paper separation device 2, and the paper on the sliding bracket 13 starts to rotate from the horizontal state or the nearly horizontal state at the starting position (the rotation angle is less than 90 degrees, preferably 70 degrees), and the rotating bracket driving device stops after the rotation is in place. After that, the sliding bracket driving device 14 drives the sliding bracket 13 to slide along the rotating bracket 12, and the paper on the sliding bracket 13 moves obliquely upward toward the side where the paper stacking area 24 is located. After the sliding bracket 13 slides into place, the sliding bracket driving device 14 stops. After that, the paper on the sliding bracket 13 is manually moved to the paper stacking area 24. The rotating bracket 12 has two extreme positions when rotating, namely, the first upper extreme position and the first lower extreme position. When the paper on the sliding bracket 13 is in the starting position, the corresponding position of the rotating bracket 12 is the first lower extreme position.

[0058] In order to facilitate moving the paper stack 16 onto the sliding bracket 13 , in this embodiment, a conveying roller 15 for conveying the paper stack 16 is rotatably mounted on the sliding bracket 13 . There are multiple conveying rollers 15 , and the axes of the conveying rollers 15 are parallel to the rotation axis of the rotating bracket 12 .

[0059] In order to facilitate the control of the working process of the paper loading machine 100, this embodiment also includes a controller, a first position sensor, a second position sensor and a third position sensor. The first position sensor, the second position sensor and the third position sensor are respectively electrically connected or wirelessly connected to the controller. The first position sensor and the second position sensor are used to monitor the height of the paper on the reversing conveyor belt 42. The first position sensor is higher than the second position sensor. The third position sensor is fixed on the rotating bracket 12. The third position sensor is used to monitor the height of the paper on the sliding bracket 13. The controller controls the actions of the rotating bracket driving device, the sliding bracket driving device 14 and the paper separation conveyor belt 22 respectively. When the solution that also includes the paper feeding device 3 is selected, the controller controls the action of the paper feeding conveyor belt 32 at the same time.

[0060] When in use, when the height of the paper on the reversing conveyor belt 42 is higher than the first position sensor, the controller controls the rotating bracket driving device, the sliding bracket driving device 14, the paper separation conveyor belt 22 and the paper feeding conveyor belt 32 to stop, the reversing conveyor belt 42 continues to move, and the height of the paper on the reversing conveyor belt 42 gradually decreases. In this process, when the height of the paper on the reversing conveyor belt 42 drops below the second position sensor, the controller controls the rotating bracket driving device, the sliding bracket driving device 14, the paper separation conveyor belt 22 and the paper feeding conveyor belt 32 to restart the action according to the set program, the reversing conveyor belt 42 continues to move, and the height of the paper on the reversing conveyor belt 42 gradually increases until the height of the paper on the reversing conveyor belt 42 is higher than the first position sensor, and the controller controls the rotating bracket driving device, the sliding bracket driving device 14, the paper separation conveyor belt 22 and the paper feeding conveyor belt 32 to stop again. The above process is repeated.

[0061] In order to facilitate the handling of paper, a fourth position sensor is fixed to the upper end of the rotating bracket 12 in this embodiment, and the fourth position sensor is electrically connected or wirelessly connected to the controller. When the top layer of paper on the sliding bracket 13 is taken away, the height of the paper stack 16 on the sliding bracket 13 is lower than the fourth position sensor, and the controller controls the sliding bracket driving device 14 to operate, so that the sliding bracket 13 slides upward until the height of the paper stack 16 on the sliding bracket 13 is higher than the fourth position sensor. The sliding bracket 13 has two limit positions when sliding, namely the second upper limit position and the second lower limit position. After the sliding bracket 13 slides upward to the second upper limit position (which can be monitored by a travel switch or other commonly used control methods), the controller controls the sliding bracket driving device 14 to operate, so that the sliding bracket 13 returns to the second lower limit position.
