Abstract: A supervisory controller determines the control status of a conveyor belt by a control unit. When it is determined that the control status of the conveyor belt is abnormal, the supervisory controller prohibits loading an article onto a traveling carriage and instructs the control unit to reset the control unit. When it is determined again that the control status of the conveyor belt by the control unit subjected to the reset instruction is abnormal, the supervisory controller prohibits loading an article onto the traveling carriage and acquires an abnormality record from the control unit. When it is determined that the control status of the conveyor belt by the control unit subjected to the reset instruction is normal, the supervisory controller acquires the abnormality record from the control unit.

Abstract: An article conveying facility in which an article is conveyed by a conveyance carriage travelling on a pair of left and right rails provided along a conveyance path. The article conveying facility includes a carriage driving apparatus that drives the conveyance carriage by utilizing a frictional force generated by contact with the conveyance carriage, and sensors that detect floating of the conveyance carriage with respect to the rails. The conveyance carriage includes a fin that contacts the carriage driving apparatus. The fin is provided so as to extend along the travelling direction of the conveyance carriage, at a lower position than the position of an upper surface of the rails. The sensors detect floating of the conveyance carriage with respect to the rails by detecting the fin.

Abstract: An article transport facility includes a main conveyor device and induction conveyors. The main conveyor device includes belt conveyors and carriage bodies. The induction conveyor includes a first conveyor device for loading article onto a second transport path and a second conveyor device that is provided for an article-loading position on a transport path and loads the article onto the belt conveyor. The first conveyor device adjusts the timing of loading the article to the article-loading position, by controlling the timing of loading the article onto the second conveyor device. The second conveyor device adjusts, on the belt conveyors, loading position of the article loaded onto the belt conveyor by controlling the timing of loading the article onto the belt conveyor.
