Goods picking method, goods picking device and goods picking system based on goods storage equipment

Abstract

The invention discloses a goods picking method, a goods picking device and a goods picking system based on goods storage equipment and relates to the technical field of warehouse logistics. One specific embodiment of the goods picking method comprises the points that the goods storage equipment comprises a main frame body and a storage layer installed on the main frame body, wherein a rotating track formed by the horizontal rotating storage layer is an inscribed circle of a warehouse map grid or is in the inscribed circle. When goods are picked based on the goods storage equipment, the goods picking method comprises the steps that transportation equipment carries the goods storage equipment where target goods are placed to a specified goods picking workstation according to a goods pickingpath specified by a carrying task, so that goods picking personnel or the goods picking equipment carries out goods picking operation; and before the goods picking operation is carried out, the goodsstorage equipment is rotated in situ until a goods picking surface where the target goods exist faces the goods picking personnel or the goods picking equipment. According to the goods picking method,the rotation track of the storage layer of the goods storage equipment is limited in the inscribed circle of the warehouse map grid, so that the goods storage equipment can rotate in situ, and the carrying efficiency and the picking efficiency are improved.

Description

technical field [0001] The invention relates to the field of warehousing and logistics, in particular to a picking method based on storage equipment, a picking device and a picking system. Background technique [0002] As the core equipment in the logistics picking process, the Automated Guided Vehicle (AGV) will transport the shelf where the target goods are located to the designated picking workstation after receiving the handling task. During the process of AGV moving the shelf, if there is no target goods on the picking surface of the shelf facing the picker, or the picking task of this picking surface has been completed, and there are picking tasks on other picking surfaces, the shelf needs to be rotated. [0003] Since the area swept by an existing shelf when it rotates is larger than the grid corresponding to the shelf on the warehouse map, the shelf will collide with the adjacent shelf during the rotation. In order to prevent the shelf from colliding with adjacent s...

AI Technical Summary

Problems solved by technology

[0005] (1) When a shelf needs to be rotated, the AGV must first transport the shelf to the steering area for rotation, and then return to the picking workstation for picking operations, which consumes the handling capacity of the AGV, and the handling efficiency is low, and the picking efficiency is low;

[0006] (2) Before the end of the rotating shelf, the grid corresponding to the steering area in the warehouse map needs to be locked, and other equipment is not allowed to pass through. Other equipment can only wait in place or re-plan the path, which is likely to cause traffic congestion and limit the traffic in the system. The upper limit of the number of AGVs limits the handling and picking capabilities of the system;

[0007] (3) Each picking workstation includes a picking position and is in charge of a picker. After the picking task of the current shelf is completed, the picker needs to wait for the departure of the current shelf and the arrival of the next shelf. The picking efficiency Low, the system's outbound capacity is poor; the picking workstation occupies a large area, but the warehouse area is fixed, resulting in a small number of picking workstations and low picking capacity of the system
