Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of logistics sorting, and in particular to a warehouse sorting equipment and a management system. Background Art
[0002] Warehouse sorting refers to the process of classifying, arranging and distributing goods according to certain rules. It is a very important part of the logistics system. When the goods arrive at the warehouse, they will be inspected and registered, and each item will be labeled or identified. The code will be recorded in the system to facilitate the subsequent sorting work. The inventory goods will be transported to the sorting location by conveyor belts, and the goods of different specified types will be collected through sorting. Finally, the goods picked in the sorting box will be packaged and packed.
[0003] The conveyor belt is a device used to transport and sort items. The speed of sorting items directly affects the efficiency of items leaving the warehouse. The current mainstream development trend of sorting conveyor belts is to set up multiple separate transversely movable sub-conveyor modules on the main conveyor belt. When the goods are transported to the designated location by the main conveyor belt, the transverse sub-conveyor belt is started to sort the items horizontally to the downstream sorting box or conveyor belt. However, due to the uncertain transverse position of the goods on the main conveyor belt, this solution has high requirements for the start timing and speed control of the transverse sub-conveyor belt. If the speed is too fast or too slow, it is easy to cause the goods to fall into the wrong channel. Therefore, it is urgent to provide a simple and efficient sorting and conveying equipment to achieve accurate and efficient transmission and sorting of designated goods. Summary of the invention
[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a warehouse sorting equipment and management system.

[0007] Above the side of the main conveyor belt opposite to the sorting conveyor belt, a sorting pushing mechanism is respectively arranged corresponding to each sorting conveyor belt, and the sorting pushing mechanism is used to push the goods to the corresponding sorting conveyor belt.
[0008] As a preferred technical solution, the sorting and pushing mechanism includes a cylinder perpendicular to the movement direction of the main conveyor belt and located on the opposite side of the main conveyor belt and the sorting conveyor belt. The output end of the cylinder faces the sorting conveyor belt, and the output end of the cylinder is connected to the push plate through a retractable connecting rod drive.
[0009] As a preferred technical solution, both sides of the push plate are bent toward the sorting conveyor belt to form a C shape.
[0010] As a preferred technical solution, a scanning device is provided at the starting point of the main conveyor belt, and the scanning device is a combination of one or more scanning devices selected from the group consisting of a code reader, a RIDF, a camera, and an infrared scanner.
[0011] As a preferred technical solution, a stacker for recovering the remaining empty pallets after sorting is further provided at the end of the main conveyor belt.
[0012] As a preferred technical solution, a sorting opening is provided on the main conveyor belt corresponding to each sorting conveyor belt; the sorting opening protrudes from the main conveyor belt and extends in a direction of gravity, presenting a certain slope.
[0013] As a preferred technical solution, the horizontal plane where the sorting conveyor belt is located is lower than the horizontal plane where the main conveyor belt is located.
