Article transport system
With a parts supply system in which a plurality of parts boxes is transported by a trolley while the parts boxes are unloaded from the trolley at respectively corresponding part-supply places provided on a parts transport route, progress status of supply of the parts boxes to respective unloading places is determined. Information of RFID tags T 1 to T 10 respectively applied to a plurality of parts boxes B 1 to B 10 is read by ID tag reading devices 4 A, 4 B and 4 C respectively mounted on trolleys 21, 22 and 23 . Thus, the respective parts boxes B 1 to B 10 that exist on the trolleys 21, 22 and 23 are identified, and information is generated on the progress status of supply of the respective parts boxes B 1 to B 10 to the part-supply places. Thus, the progress status of the supply of the parts boxes B 1 to B 10 to the part-supply places is recognized.
