ABSTRACT:
A working apparatus for a work being conveyed wherein a movable base is provided alongside of a conveyor conveying a plate-like workpiece mounted on a carrier in such a manner that the workpiece is held in an upright posture with its side surfaces facing sideward, the movable base being movable in the longitudinal direction in which the workpiece is conveyed, and a robot mounted on the movable base is used to apply predetermined working to the workpiece being conveyed by the conveyor. A clamping device for clamping the carrier is provided on the movable base and operated by signals from a detecting device that detects the carrier. A positioning mechanism is also provided on the movable base, for positioning the workpiece on the carrier in three orthogonal directions with respect to the movable base and holding the workpiece in that position. The positioning mechanism includes a vertically movable lifter for pushing the workpiece up from below to a predetermined position, a first unit having a reference seat for receiving one of the front and rearward side edges of the workpiece and a first clamp member for clamping the one side edge from sideward direction and a second unit having an abutment seat for contacting the other of the front and rearward side edges of the workpiece and a second clamp member for clamping the other side edge from sideward direction. The first unit is mounted on the movable base to be movable laterally toward and away from the conveyor. The second unit is also mounted on the movable base to be movable laterally toward and away from the conveyor and additionally movable in the longitudinal direction.
