Claims

[Scope of Claim for Utility Model Registration] In a transport work abnormality detection mechanism for an automatic guided vehicle that automatically transports a transported object by automatically controlling each operation of traveling, stopping, and turning, a loading section on which the transported object is loaded; a contact section disposed close to the loading section; a contact section attached to the conveyed object so as to be freely connectable to the contact section when the conveyed object is loaded on the loading section;
a detection unit that detects the presence or absence of obstacles, displacement of the conveyed object, and other abnormal conditions during the conveyance operation; A transport work abnormality detection mechanism for an automatic guided vehicle, comprising a processing circuit that performs abnormality processing based on this determination.
