Problems solved by technology

[0005] When automatic picking is carried out with a serial picking strategy, the following items always have to wait for the previous items to be picked before starting to pick. Compared with parallel picking, it will inevitably generate a lot of waiting time; especially for orders with little demand for single items, The accumulation of waiting time will greatly affect the picking efficiency of the system

Embodiment Construction

[0021] A hybrid picking strategy combining series and parallel. Such as image 3 As shown in Fig. 1, when the picking operation is carried out with a single-order serial-parallel mixed picking strategy, the received order is firstly preprocessed to determine whether the order can be partially or completely parallel picked. strategy selection. For some orders that are picked in parallel, it is judged whether there is a gap between the picked items on the conveying system. If there is a gap, select the item that can be picked by using the gap among the unpicked items for interstitial picking. For the last remaining unpicked items, pick according to the serial picking strategy. After all the items required by the order have been picked and ejected and conveyed out of the picking area, the next order starts to be picked.

[0022] Let the total number of batches of orders be M, the total number of items contained in the batch of orders be N, and the number of pickers equal to th...

Abstract

A product mixed sorting method comprises the following steps: (1) pretreating a received order, determining whether the order can be partially or completely subjected to parallel sorting, if yes, preferentially performing parallel sorting, or else, performing sorting according to a serial sorting strategy; (2) aiming at an order which is partially subjected to parallel sorting, determining whether gaps exist among products in a conveying system after sorting, and if yes, performing gap-insertion sorting on to-be sorted products by utilizing selecting utilizable gaps in unsorted products; (3) sorting finally-residual unsorted products according to the serial sorting strategy; and (4) starting to perform sorting for a next order after all products needed by the order are completely sorted, ejected and conveyed out of a sorting zone. The invention also discloses a sorting time calculation method for product mixed sorting. The product mixed sorting method helps to solve the problems that in a conventional serial sorting strategy, cargos are mixed and overlapped together in a conveying system, cannot be subjected to direct regular packaging and are not easy to count and identify, and is improved in sorting efficiency and saved in sorting time compared with the serial sorting strategy.

Description

technical field [0001] The present invention relates to a product mixed picking strategy, in particular to a product mixed picking method and a picking time calculation method. Background technique [0002] The product picking using the single-item automatic picking system based on the ejection device (hereinafter referred to as the automatic picking system) is widely used in large-scale retail distribution centers such as medicine and tobacco. It has the characteristics of high picking efficiency, low error rate, and low labor cost. It is suitable for Multi-variety, small-batch, and regular-shape products are dismantled and batch-order-picked. [0003] According to different combinations of sorting machines and conveying systems, there are many types of automatic picking systems; generally, an automatic picking system with a single type of picking machine configured on one side of a single conveying system can be called a basic automatic picking system. This kind of system...
