Item sorting system and method

Abstract

The invention discloses an article sorting system and method. The system includes: a server and multiple handling robots; multiple handling robots run in the storage area, and multiple sets of grids are deployed in the storage area, and each set of grids includes at least: the first type of grid and the second type of grid; server configuration In order to determine that the number of items loaded in the loading container reaches the preset threshold, it is the target grid. When the target grid is the second type of grid, determine the first obstacle grid that hinders the transfer of the target grid. Assign a transfer robot to the first obstacle grid and the target grid respectively, and send a transfer instruction to the transfer robot; The object container is removed; the second transport robot is configured to drive to the target grid position in response to the transport command, and transport the load container at the target grid position to the packaging table. The invention improves the sorting efficiency of articles.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of intelligent logistics, and in particular to an item sorting system and method. Background technique [0002] With the development of e-commerce, severe requirements are put forward for the logistics industry. For example, how to efficiently and accurately sort logistics items, etc. [0003] At present, the following two methods are often used for sorting items: Method 1, as shown in Figure 1(a), adopts a steel platform-type sorting structure, and controls the robot to receive the items provided by the supply table on the steel platform, and combines the steel The auxiliary equipment set on the platform delivers the items to the grid on the steel platform; the second method, as shown in Figure 1(b), adopts a landing zigzag sorting structure, and controls the robot to land on the grid with the grid. The zig-zag sorting field receives the items provided by the supply platform, so ...

Problems solved by technology

[0004] However, the above two sorting methods have the following problems. For the first method: although the purpose of item sorting can be achieved, it takes a lot of cost to build a steel platform, and the steel platform is not easy to expand, so that the robot performs item sorting on the steel platform During the task, the flexibility is poor, and it is easy to be limited by the number of auxiliary equipment, resulting in a decrease in the efficiency of item sorting; for the second method: when the number of robots is large and the density is high, the robot is prone to congestion in the sawtooth area when performing item sorting tasks , leading to a decrease in item sorting efficiency
