Cargo-to-person sowing and sorting integrated workstation and sorting method thereof

Abstract

The invention provides a cargo-to-person sowing and sorting integrated workstation and a sorting method thereof. The cargo-to-person sowing and sorting integrated workstation comprises at least one sorting table, an output floor changing elevator, conveying lines and a control system, wherein each conveying line comprises a corresponding main conveying line used for supplying and discharging cargoes and a corresponding plurality of auxiliary conveying lines, the main conveying lines are provided with first ends and second ends correspondingly, the first ends are used for inputting cargo sourceboxes from an external storage area, the second ends output order boxes on the conveying lines to the outside through the output floor changing elevator, a plurality of floors of cargo shelves are arranged on the sorting table, each floor of cargo shelf is provided with a plurality of stations, the stations comprise cargo source box stations and order box stations, each floor of cargo shelf is provided with the corresponding conveying line, one of the corresponding conveying line comprises the corresponding main conveying line, and the other of the corresponding conveying line comprises corresponding auxiliary conveying lines. The sorting method is high in automation degree, high in sorting efficiency, low in labor intensity, low in flow requirement for a box type vertical warehouse and the conveying lines, low in cost, diversified in service form and high in universality.

Description

technical field [0001] The invention relates to the technical field of picking in logistics warehousing, in particular to a goods-to-person spreading and picking integrated workstation and a picking method thereof. Background technique [0002] In recent years, with the rapid development of computers and e-commerce, it has not only brought opportunities for the rapid rise of the automated logistics and warehousing industry, but also brought unprecedented challenges to the warehousing and logistics industry. [0003] At present, the picking mode of supplying goods by conveyor line mainly adopts two modes of goods-to-person picking station or spreading wall: [0004] The first is to use a box-type three-dimensional warehouse. The material boxes are transported to the picker by the transmission line. The picker picks the goods according to the order, and then the transmission line transports the material box back. Picking stations are usually divided into single layer (1 sourc...

AI Technical Summary

Problems solved by technology

This type of model is universal, but it is necessary to distinguish between the order box supply layer 11 and the source box supply layer 12, so the number and area of ​​source box stations and order box stations are fixed, and cannot be customized according to different order characteristics and orders. The demand is dynamically adjusted, and the adaptability is poor. Relatively speaking, the number of source boxes supplied at the same time is limited, and the number of matching orders during picking is small. Each time the source of goods is supplied to the picking station, the probability of picking multiple times (orders are repeated on average) Picking hit rate) is low, so the number of times the source box enters and exits the box-type vertical warehouse is more, the flow demand of the opposite warehouse and the flow demand of the conveyor line are relatively high, and the overall efficiency depends on the overall supply capacity of goods to people and the scheduling plan, but the scheduling Rigid and strong, the overall picking efficiency is not high

At the same time, due to the need to improve supply capacity and efficiency, such as the layered cargo picking method and system with the patent application number CN201610825164.7, it improves the picking efficiency to a certain extent compared with the traditional picking station, and adopts a double-layer picking station (such as Figure 7 The number 11 is the supply layer, and the number 12 is the delivery layer), and each layer must be designed with independent supply and delivery output conveyor lines and buffers. The overall process plan is relatively complicated and the cost is high

[0005] The second method is the sowing wall order processing method. The sowing wall is generally designed according to the number of order customers in the wave. Before sowing, the goods are collected according to the wave order. B-terminals or small B-terminals (stores or convenience stores) are supplied in batches in a centralized manner. The spreading wall is generally used when the business form is relatively fixed and the business volume does not fluctuate greatly. poor versatility

At the same time, because the picking mode of the spreading wall requires the staff to pick the goods from the conveyor line to the spreading wall (or vice versa), a large number of twisting operations will cause labor injuries, which is not conducive to the occupational health of employees, and the labor intensity is high
