Abstract

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.
