[0002] In the process of office supplies production, office supplies are usually placed in packaging boxes for packaging, and then the packaging boxes are placed in the warehouse for storage. In order to ensure the cleanliness of the warehouse, the packaging boxes are usually stacked together in the stereoscopic warehouse;

[0003] Most of the existing stacking devices use stackers, which usually clamp the boxes one by one, then use a hoist to lift the boxes to a specified height, and then use the forks on the loading platform to perform telescopic movements to place the boxes at a high place, and then stack the boxes together one by one. This method allows only one box to be placed at a time. After the box is placed, it is necessary to wait for the loading platform to be reset before the next box can be placed again, resulting in a poor stacking efficiency of the boxes. After the boxes are stacked to a certain height, this placement method may cause the boxes to be stacked unstable, causing the stacked boxes to topple over, and causing damage to the office supplies in the boxes. Therefore, it is necessary to design a stacking device and stacking system for office supply boxes to solve the above problems. Summary of the invention

The power supply, the conductive rod, the two conductive sheets and the two electromagnets 13 form a loop through wires.

[0035] A stacking system for office supplies packaging boxes is composed of the above-mentioned stacking device.

[0036] The functional principle of the present invention can be explained through the following operation mode: the first motor 10 is started, so that the first motor 10 drives the second rotating rod 19 and the conveying roller to rotate, so that the conveyor belt 9 runs, and then the packaging boxes are placed on the conveyor belt 9 in sequence at equal intervals, so that the conveyor belt 9 drives the packaging boxes to move to the left;

[0037] In the process of the packing box moving to the left, since the rotating gear 34 and the incomplete gear 33 are not in meshing state at this time, the inclined plate 24 is tilted to the right, so that when the packing box is conveyed to the left, under the action of the inclined plate 24 and the partition plate 29, the packing box moves to the front side of the partition plate 29, and then continues to be conveyed to the left until the packing box contacts the limit frame 16, and the packing box will stay on the left side of the conveyor belt 9;

[0038] As the conveyor belt 9 continues to run, the second rotating rod 19 on the left side rotates through the first transmission assembly 20 to drive the two screw rods 22 to rotate, and the screw rod 22 on the front side rotates through the second transmission assembly 27 to drive the third rotating rod 26 to rotate. Since the two bevel gears 32 are in a meshing state, the transmission rod 31 is driven to rotate, and then the incomplete gear 33 is driven to rotate;

[0039] When the packaging box moves to the front side of the partition plate 29, the incomplete gear 33 will mesh with the rotating gear 34, so that the rotating gear 34 drives the vertical rod 35 to rotate, and then the vertical rod 35 drives the inclined plate 24 to rotate toward the front side, and the packaging box placed behind will be transported to the rear side of the partition plate 29;

[0040] When the packaging box moves to the rear side of the partition plate 29, the incomplete gear 33 is no longer meshed with the rotating gear 34, so that under the elastic action of the torsion spring 36, the vertical rod 35 drives the inclined plate 24 to rotate backward and reset, and the next packaging box placed will be transported to the front side of the partition plate 29;

[0041] According to the above method, multiple packaging boxes are stacked on both the front and rear sides of the partition plate 29;

[0042] During the transportation process, the packaging box will contact the inclined plate 24, so that the packaging box may be tilted on the front and rear sides of the partition plate 29, so the packaging box can be corrected by rotating the two screw rods 22;

[0043] During the rotation of the two screw rods 22, the two moving plates 21 will continuously move relative to or away from each other. When the two moving plates 21 move relative to each other, the two clamping plates 23 will be driven to move relative to each other, thereby pushing the packaging box, so that the packaging box contacts the partition plate 29. As the moving plates 21 continue to move, the packaging box is deflected, so that the front and rear sides of the packaging box contact the clamping plates 23 and the partition plate 29 respectively, so that each packaging box can be flatly placed in the left area of ​​the conveyor belt 9.

[0044] It is worth mentioning that, since the packaging boxes are placed on the conveyor belt 9 at equal intervals, when the packaging box just moves between the clamping plate 23 and the partition plate 29, the clamping plate 23 moves toward the partition plate 29. When the clamping plate 23 moves back to its original position, the next packaging box just moves between the clamping plate 23 and the partition plate 29.

[0045] When the number of boxes stacked on the front and rear sides of the partition plate 29 reaches a specified number, the staff stops placing boxes on the conveyor belt 9, and the first motor 10 continues to run. When the two clamping plates 23 come into contact with multiple boxes again, the staff turns off the first motor 10 and starts the second motor 28, so that the first rotating rod 3 rotates ninety degrees, thereby rotating the conveyor belt 9 and the boxes to a vertical state.

[0046] After the first rotating rod 3 rotates ninety degrees, the conductive rod 5 will contact the two conductive sheets, so that the two electromagnets 13 are energized. After the two electromagnets 13 are energized, they will generate an attractive force on the corresponding sliders 15, so that the two sliders 15 drive the corresponding limit frames 16 to move back to each other, so that the through opening is opened. At this time, under the action of gravity, the packaging box falls vertically on the placement board of the warehouse (since pads are placed above and below the placement board of the warehouse to separate the packaging box from the ground and prevent the packaging box from getting wet, there will be a large gap between the placement board and the ground. When stacking the packaging boxes, it is necessary to push the left part of the bottom plate 1 to the bottom of the placement board, so that after the conveyor belt 9 is turned over, the packaging box can be stacked just above the placement board);

[0047] During the rotation of the conveyor belt 9 and the stacked packaging boxes, the blocking rod 17 will be located in front of the multiple packaging boxes, so as to prevent the packaging boxes from tipping over when they are turned over. After the packaging boxes are placed, the movement of the limit frame 16 will drive the two blocking rods 17 to move away from each other, so that the blocking rod 17 is away from the packaging boxes. Therefore, after the stacked packaging boxes are placed, the staff can push the device to the right, so as to move the device away from the stacked packaging boxes. Then the staff controls the second motor 28 to drive the first rotating rod 3 to rotate in the opposite direction, so that the conveyor belt 9 is reset and can be used again (after the first rotating rod 3 rotates in the opposite direction, the conductive rod 5 will be away from the two conductive sheets, so that the two electromagnets 13 are powered off, and under the elastic action of the spring 14, the two limit frames 16 are reset).

[0048] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
