ABSTRACT:
A transport system for transporting workpieces through machining stations of a press device. The transport system includes at least one independent transport device dedicated to each machining station, the transport device being effective for receiving and transporting a workpiece in at least one of a 2-axial and a 3-axial transport motion. The transport system includes a longitudinal transport device for effecting a horizontal longitudinal motion of the workpiece in a transport direction of the workpiece and having a horizontally extending extension arm for transporting the workpiece between machining stations. The extension arm includes guides, and a transport slide for transporting the workpiece in the transport direction. The transport slide is disposed on the guides for being longitudinally movable thereon and has coupling device thereon for coupling one of a suction beam and a gripper arrangement to the extension arm for effecting a reception of the workpiece by the longitudinal transport device. The transport system further includes: a lifting mechanism operatively connected to the longitudinal transport device for effecting a vertical motion of the workpiece; and a closing-opening mechanism operatively connected to the longitudinal transport device and the lifting mechanism for effecting a transverse motion of the workpiece with respect to the transport direction thereof.
