An article conveyance apparatus couples a plurality of conveyor carriages for conveying articles and enables the coupled conveyor carriages to travel along a conveyance path K. The conveyor carriage is coupled by a coupling part to another conveyor carriage placed in the longitudinal direction with respect to a traveling direction H of the conveyor carriage. The conveyor carriage includes a load cell that is provided in the coupling part and measures a force applied between the conveyor carriages, and a controller that calculates a force F applied to wheels of the conveyor carriage, based on a tension T between the conveyor carriages calculated according to the force applied between the conveyor carriages and measured by the load cell.

Article conveyance apparatus

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.

Article transport facility

A sorting facility for sorting an article by a belt conveyor provided on a traveling carriage traveling along a conveyance path. A plurality of traveling carriages travel on the conveyance path. Each of the plurality of traveling carriages is provided with a power generation motor generating electric power by traveling of the traveling carriage. The belt conveyor provided on each of the plurality of traveling carriages is driven in a predetermined position on the conveyance path by the electric power generated by the power generation motor. The power generation motor provided in each of the plurality of traveling carriages starts generation of the electric power necessary to drive the belt conveyor in order from the power generation motor provided in the traveling carriage scheduled to pass the predetermined position on the conveyance path first, after the traveling carriages are actuated and traveling speeds become a constant speed.

Sorting facility

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.

Article conveying facility

A sorting facility for sorting articles by a plurality of connected conveyance carriages. The sorting facility includes a supervisory controller managing a position of each of the conveyance carriages, a trigger sensor detecting each of the conveyance carriages, and a belt conveyor provided on each of the conveyance carriages. The supervisory controller identifies each of the conveyance carriages that should deliver the articles to the chute based on the managed position of each of the conveyance carriages. The supervisory controller instructs the belt conveyor provided in each of the conveyance carriages identified to start a delivery operation of each of the articles at timing when each of the conveyance carriages identified is detected by the trigger sensor.

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.
