Traditional warehouse picking takes up 40%-50% of the time to process all orders, and walking for picking takes up 50% of the time. Walking is the most time-consuming and labor-intensive part of manual picking, which is also the bottleneck of picking efficiency. Manual picking should be familiar with the picking process, understand the approximate location of the goods inventory with the support of the matching system, and arrange the picking path reasonably. The maximum daily picking volume for a single person is about 1,500 pieces. However, new technologies such as automation and robots have replaced the traditional manual picking method.
Picking requires the process of selection, transportation, and concentration: in the traditional “man-to-goods” picking method, the man and the animal are stationary, and the picker brings the picking container to the storage location of the goods to be picked according to the picking list or under the guidance of the system to pick; in the “goods-to-man” picking system, the man is stationary and the object is moving, and the AGV (Automated Guided Vehicle) shelf or automatic sorting system delivers the goods to be picked to the picking workbench, and then the goods to be picked are picked out manually or automatically. People do not need to walk at the picking station, and the daily picking volume reaches more than 3,000 pieces, and the safety of the workplace is improved.
