  • Patent number: 10537932
    Abstract: 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.
