Patent ID: 11733086

Abstract:
In order to suppress the collection of articles that are different from those specified when collecting articles using an article transport vehicle from a plurality of accommodating portions that accommodate articles, an article transport vehicle (3) includes a control portion (15), and a weight detecting portion (18) that detects a total weight (W) of articles (B) supported by a support portion (12), wherein articles picked up from accommodating portions (1) are supported by the support portion (12). In a case in which an increased weight (ΔW), which is an increase in the total weight (W) when an article (B) is newly supported by the support portion (12), is out of a prescribed range (WL, WH) according to a weight (BW) of a target article, which is an article (B) that is to be picked up from the accommodating portion (1), the control portion (15) determines that the target article was not correctly picked up, and makes a notification giving error information.
