ABSTRACT:
A picking cart and a picking system capable of improving sorting precision and operating efficiency. The picking cart comprises a plurality of storage shelves at least one of which has a container placed thereon in a drawable manner, a display unit for displaying at least an article to be picked and one of the storage shelves to which the article is to be delivered, a sensor unit for detecting whether or not the container placed thereon has been drawn from each of the storage shelves, and a determination unit for determining whether or not one of the storage shelves from which the container placed thereon has been drawn is identical to the storage shelf displayed on the display unit, based on the detection result of the sensor unit. Before an article is placed in a container, that is, when a container is drawn, it is possible to know whether or not sorting has been carried out just as displayed.
