Autonomous mobile robots for picking and placing goods on shelves, and warehousing system and method

Abstract

The invention discloses autonomous mobile robots for picking and placing goods on shelves, and a warehousing system and method. The autonomous mobile robots each comprise a moving base plate and a support body. The support bodies can rise and fall relative to the moving base plates and can stretch out of the moving base plates bi-directionally and horizontally, and the stretching-out directions ofthe support bodies are perpendicular to the linear motion directions of the moving bases. The autonomous mobile robots can walk in passages between shelf arrays for goods picking and placing. The autonomous mobile robots for picking and placing the goods on the shelves, and the warehousing system and method are suitable for carrying large materials, the autonomous mobile robots are low in manufacturing cost and compact in structure; the goods picking and placing directions of the support bodies of the autonomous mobile robots are perpendicular to the linear motion directions of the autonomousmobile robots, therefore, the robots do not need to frequently change the postures in the passages between the shelves, and the operation efficiency is improved; and the robots are compact in structure, therefore, the placing density of the goods in a warehouse can be increased, and the storage efficiency of the warehouse is improved.

Description

technical field [0001] The invention relates to the field of warehousing and logistics, in particular to the technical field of picking and placing goods in warehousing and logistics. Background technique [0002] At present, in the field of warehousing and logistics, there have always been many difficulties in picking up large-scale materials from the shelves. At present, in most warehouses, the picking and placing of large-scale materials still needs to rely on forklifts. Forklifts have the advantages of carrying heavy loads and lifting forks to pick up goods. The following obvious disadvantages: [0003] (1) The forklift is large in size, and there needs to be a large enough aisle between the shelves for the forklift to move, which indirectly reduces the storage density of the warehouse and affects the storage capacity of the warehouse; [0004] (2) The forklift direction is parallel to the direction of linear motion. When you need to fork the goods from the shelf, you n...

AI Technical Summary

Problems solved by technology

[0003] (1) The forklift is large in size, and there needs to be a large enough aisle between the shelves for the movement of the forklift, which indirectly causes the storage density of the warehouse to decrease and affects the storage capacity of the warehouse;

[0004] (2) The pick-up direction of the forklift is parallel to the direction of linear movement. When goods need to be forked from the shelf, it is necessary to control the forklift to move perpendicular to the aisle, and then control the forklift to rotate 180 degrees so that it moves parallel to the aisle to transport the goods out. It is necessary to frequently adjust the posture of the forklift, which is difficult to operate and low in efficiency;

[0005] (3) Manual forklifts rely on the technical level of labor, and the labor cost is high, while the cost of automatic forklifts is high, so both manual forklifts and automatic forklifts have the problem of high cost of use
