Article sorting system and method

Abstract

The invention discloses an article sorting system and method. The system involves a control server, a first robot and a second robot; the first robot and the second robot operate in a storage area ofthe article sorting system; at least one cargo collection container is arranged in the storage area, and each cargo collection container comprises at least two sub-grids; the control server is configured to determine a target sub-grid from the at least two sub-grids of the at least one cargo collection container and send a sorting instruction to the first robot, and send a carrying instruction tothe second robot when the target sub-grid is the first sub-grid of the first cargo collection container and articles contained in the first sub-grid reach a first preset threshold value; the first robot is configured to respond to the sorting instruction and deliver the articles to the first sub-grid; and the second robot is configured to respond to the carrying instruction, travel to the positionof the first cargo collection container and carry the first cargo collection container to a packaging table specified by the carrying instruction. According to the system and method, the article sorting efficiency is improved.

Description

Technical field[0001]The embodiment of the present invention relates to the field of intelligent logistics technology, 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 sort logistics items efficiently and accurately.[0003]At present, the following two methods are often used for sorting items: Method one, as shown in Figure 1(a), adopts a steel platform sorting structure, and controls the robot to receive the items provided by the supply table on the steel platform, and combine it with steel The auxiliary equipment set on the platform delivers the items to the grid opening on the steel platform; the second method, as shown in Figure 1(b), adopts a floor sawtooth sorting structure, and controls the robot to land on the grid opening. The zigzag sorting field receives the items provided by the supply table to deliver the items to the...

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
