Line-up and rotation method, device and system for goods shelves

Abstract

The invention discloses a line-up and rotation method, device and system for goods shelves, and relates to the field of logistics automation. The line-up and rotation method for the goods shelves comprises the following steps of: lining up and scheduling carrying tools for carrying the goods shelves while distributing carrying tasks; according to the order requirements, planning paths for carryingthe goods shelves by the carrying tools for the carrying tools, and regulating operating paths of the carrying tools in real time; performing real-time detection on a surrounding environment in whichthe goods shelves are located from carrying task distribution to carrying task accomplishment; and rotating the goods shelves if the surrounding environment in which the goods shelves are located issuitable for rotating. Lining up and scheduling are expanded to the whole area, so that the defect that a fixed line-up area only can limited number of robots is overcome; and path rotation points areflexibly and dynamically set, so that the defect that circulation is poor as a rotation area is fixed is overcome, and therefore, goods shelf carrying efficiency is improved.

Description

technical field [0001] The invention relates to the field of logistics automation, in particular to a method, device and system for queuing and rotating shelves. Background technique [0002] At present, the logistics automation technology is booming, and the robot goods-to-person system has been widely used in the warehousing industry of western developed countries due to its advantages of flexibility and low cost. In traditional warehouse operations, the shelves are fixed, and operators need to walk to the designated storage space to carry out operations. The robot goods-to-person system is different from the traditional operation method. The shelves are transported to the workbench by mobile robots and queued up. The personnel operate on the workbench without walking. The robot goods-to-person system greatly improves the efficiency of personnel work. [0003] In the existing robotic goods-to-person system, the mobile shelf can be placed on multiple sides, and the front, ...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is that the number of robots that can be accommodated in the fixed queuing area is limited, and the robots that cannot be accommodated will stay in the aisle and block the path of other robots

The queuing path is relatively fixed, and it is easy to cause path deadlock

In this method, the surface-turning area is fixed, which is likely to become a bottleneck of efficiency. When multiple robots need to switch surfaces, the queued robots wait for the release of the surface-turning area, so that the circulation becomes poor.
