Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation technology, and in particular to a visual recognition speed difference separation device for stacked items in logistics. Background Technology

[0002] In the logistics sorting process, it is common to encounter situations where two or more box-type packages and envelope-type packages are stacked together. Stacking separation devices are processing equipment designed to separate stacked packages. They typically have multiple conveying mechanisms along the conveying direction, with the discharge end of the upstream conveying mechanism being higher than the infeed end of the downstream conveying mechanism. This creates a height difference between the two conveying mechanisms, allowing the stacked packages to be completely separated or partially staggered after falling. Based on this, multiple drops formed by multiple conveying mechanisms ultimately complete the separation of the stacked packages.

[0003] In the existing technology, most traditional stacking separation devices are fixed structures with fixed heights for their crawling conveyor belts. The height of the crawling conveyor belts cannot be adjusted, thus making it impossible to adjust the height difference between the two crawling conveyor belts. This design makes it easy to damage fragile items when the stacking packages being separated contain such items, thereby reducing the practicality of the stacking separation device.

[0025] To adjust the height of the crawling conveyor belt 3, a servo motor 11 is fixedly installed on the upper surface of the middle position of the base plate 6. A threaded rod 12 is fixedly installed at the output end of the servo motor 11. A lifting cylinder 13 is fixedly installed on the lower surface of the crawling conveyor belt 3 mounting bracket. The lifting cylinder 13 is sleeved on the outer surface of the threaded rod 12. The inner wall of the lifting cylinder 13 has a threaded groove that meshes with the threaded rod 12.

A slider 15 is fixedly installed on the side wall of one docking plate 14, and a sliding groove that matches the slider 15 is opened on the side wall of the other docking plate 14.

[0026] By setting up a base 1, a parallel conveyor belt 2, a crawling conveyor belt 3, an anti-fall frame 4, a vision camera 5, a base plate 6, a sleeve frame 7, a lifting plate 8, a limit block 9, a limit bolt 10, a servo motor 11, a threaded rod 12, a lifting cylinder 13, a docking plate 14, and a slider 15, the height of the crawling conveyor belt 3 can be adjusted. By adjusting the height of the crawling conveyor belt 3, the height difference between two adjacent crawling conveyor belts 3 can be adjusted, thereby preventing damage to items and improving the practicality of the stacking separation device.

[0027] The upper surface of the fall arrestor 4 is provided with an installation component, which includes an installation port 16. The installation port 16 is opened through the upper surface of one end of the fall arrestor 4. An installation frame 17 is fixedly installed on the upper surface of the fall arrestor 4 around the installation port 16. An installation block 18 is provided inside the installation frame 17. A fixing block 19 that is inserted into the installation port 16 is fixedly installed on the lower surface of the installation block 18. A vision camera 5 is fixedly installed at the bottom end of the fixing block 19. A positioning block 20 is fixedly installed on the inner wall of the installation frame 17. A positioning groove that matches the positioning block 20 is opened on the outer surface of the installation block 18. A fixing bolt 21 is threadedly connected to the outer wall of the installation frame 17. The fixing bolt 21 passes through the outer wall of the installation frame 17 and is inserted into the installation block 18. A pull handle 22 is fixedly installed on the upper surface of the installation block 18.

[0028] By setting up the installation port 16, installation frame 17, installation block 18, fixing block 19, positioning block 20, fixing bolt 21 and pull handle 22, the function of quickly and conveniently assembling and disassembling the vision camera 5 is realized, which improves the installation method of the vision camera 5 in the prior art. When the vision camera 5 is damaged, it can be quickly disassembled and assembled, thereby facilitating the replacement or repair of the vision camera 5 and further enhancing the practicality of the stacking separation device.

[0029] Working principle: When using the stacked package separation device to separate stacked packages, the parallel conveyor belt 2 transports the stacked packages. When the stacked package moves to the end of the parallel conveyor belt 2 and contacts the crawling conveyor belt 3, the crawling conveyor belt 3 transports the stacked package. During the transportation process, the vision camera 5 captures and identifies the packages. When the stacked package reaches the top of the first crawling conveyor belt 3, it falls down onto the second crawling conveyor belt 3. During this process, because the packages below contact the crawling conveyor belt 3 first, the stacked packages are completely separated or partially misaligned after falling. Then, after passing through multiple crawling conveyor belts 3, the stacked packages are completely separated.

[0030] When the height of the crawling conveyor belt 3 needs to be adjusted, first loosen the limiting bolt 10 on the outer wall of the sleeve 7, causing the limiting bolt 10 to extend away from the sleeve 7. After the limiting bolt 10 slides out of the limiting hole, the fixing of the lifting plate 8 is released. Then, start the servo motor 11. When the servo motor 11 runs, it drives the threaded rod 12 to rotate clockwise or counterclockwise. During the rotation of the threaded rod 12, the threaded rod 12 drives the lifting cylinder 13 to move through the threaded groove. Under the action of the sleeve 7 and the lifting plate 8, the lifting cylinder 13 drives the crawling conveyor belt 3 to rise and fall. The lifting plate 8 slides inside the sleeve 7, limiting... The position block 9 slides inside the limiting groove, while the docking plate 14 on the crawling conveyor belt 3, which is lifting and lowering, slides on the side wall of the docking plate 14 on the fixed crawling conveyor belt 3. The slider 15 slides inside the slide groove. When the crawling conveyor belt 3 is lifted and lowered to a suitable height, the servo motor 11 is turned off, so that the height of the crawling conveyor belt 3 no longer changes. Finally, the limiting bolt 10 is turned in the opposite direction, so that the limiting bolt 10 is turned back into the limiting hole, fixing the lifting plate 8, thereby fixing the crawling conveyor belt 3 and completing the height adjustment of the crawling conveyor belt 3. Repeat the above operation to adjust the height of multiple crawling conveyor belts 3.

[0031] When the visual camera 5 needs to be replaced or repaired, first loosen the fixing bolt 21 so that the fixing bolt 21 extends away from the mounting frame 17. After the fixing bolt 21 separates from the mounting block 18, release the fixing of the mounting block 18. Then, pull the mounting block 18 upward by pulling the handle 22 so that the mounting block 18 slides upward inside the mounting frame 17. The positioning block 20 slides inside the positioning groove. The fixing block 19 drives the visual camera 5 to slide upward inside the mounting opening 16. After the visual camera 5 slides out of the mounting opening 16, the disassembly of the visual camera 5 is completed. At this time, the visual camera 5 can be replaced or repaired. After the visual camera 5 is replaced or repaired, reverse the above operation and reinstall the visual camera 5 inside the fall arrestor 4.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
