A transport apparatus for transferring workpieces in a processing device includes at least two stations having at least two gripping tool units arranged on a gripping tool support which is movable back and forth between the stations of the processing device. The gripping tool support is movably mounted so as to be linearly guided and mounted by a parallelogram guide arrangement so as to be displaceable transversely with respect to its linearly guided movability. The gripping tool support is movable by a gripping tool support drive with two crank gear arrangements each having a gripping tool support drive motor.

Transport apparatus for transferring workpieces in a processing device

In a transport method for transferring workpieces between a plurality of successive stations of a processing device, especially a forming device, workpieces are in each case transported from one station to the respective next station of the processing device simultaneously by means of a plurality of gripping tools which are movable jointly in a transport cycle. In the event of a process disturbance, the transport cycle is suspended and the gripping tools with the workpieces are moved into a waiting position in which the workpieces are outside the operating range of processing tools of the stations of the processing device. Once the process disturbance has been eliminated, the transport cycle of the workpieces is resumed. By virtue of the movement of the gripping tools into a safe waiting position outside the operating range of the processing tools of the stations, consequent damage resulting from the process disturbance can be prevented.

Transport method for transferring workpieces

In a multistage forming machine, an apron is screwed to a press slide. At its upper end, the apron has six elongated clamping cams, distributed over its width, while four upwardly projecting clamping lugs are fitted at is lower end. Suspended in the apron is a combined tool block with a wedge-shaped supporting plate. Four clamping lugs, distributed over the width, are formed at the upper end of the supporting plate, while four clamping cams are formed at the lower end. The clamping lugs of the combined tool block are suspended by means of the clamping cams of the apron, while the clamping cams of the combined tool block are inserted between the clamping lugs and the main part of the apron. By means of two clamping devices, a clamping force acting in the vertical direction of the combined tool block is produced, bringing about a clamping of the combine tool block and the press slide in the horizontal direction.
