Item sorting system and method

Abstract

The invention discloses an article sorting system and method. The system includes: a control server, a first robot and a second robot; the first robot and the second robot respectively operate in the storage area of ​​the item sorting system; at least one cargo container is deployed in the storage area, and each cargo container includes at least Two sub-grids; the control server is configured to determine the target sub-grid from at least two sub-grids of at least one collection container, and send a sorting instruction to the first robot; and when the target sub-grid is the first collection container The first sub-grid, and when the items contained in the first sub-grid reach the first preset threshold, a handling instruction is sent to the second robot; the first robot is configured to respond to the sorting command and deliver the items to the first sub-grid mouth; the second robot is configured to respond to the handling instruction, drive to the position of the first cargo container, and transport the first cargo container to the packing platform specified by the handling instruction. 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 conditions have been 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 sorting structure, by controlling the robot to receive the items provided by the supply table on the steel platform, and combining the steel The auxiliary equipment set on the platform delivers the items to the grids 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 grids. 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
