Abstract: A hemming system includes a processing station; a processing robot for performing hemming on a workpiece in the processing station; a die storage for storing dies for hemming in association with types of workpiece; a first-stage changing station in which a die used by the processing robot when performing hemming on a next different type of workpiece and corresponds to the next different type of workpiece is disposed on standby; first transfer means for transferring the die in the first-stage changing station to the processing station; a second-stage changing station in which the die disposed in the processing station is temporarily disposed; second transfer means for transferring the die disposed in the processing station to the second-stage changing station; and a mobile robot for moving the die from the second-stage changing station to the die storage and move the die from the die storage to the first-stage changing station.
