PCT No. PCT/SE86/00449 Sec. 371 Date Apr. 6, 1989 Sec. 102(e) Date Apr. 6, 1989 PCT Filed Oct. 6, 1986 PCT Pub. No. WO88/02301 PCT Pub. Date Apr. 7, 1988.A loading elevator for a multi-platen press is provided with a pusher which simultaneously transfers a number of transport plates loaded with stampings to the press. After press operations are completed, the plates are unloaded by an extractor to an unloading elevator. The pushing and the unloading of the plates are automatic, with sensors provided to halt the loading and unloading in the event of excessive resistance to the movement of any one of the plates. A plurality of sensors are provided in the pusher and in the extractor, one sensor there for each of the plates. Each sensor is connected to halt the operation on recognition by the sensor that an express resistance exists and if desired to provide a signal that the halting has taken place. At the unloading elevator, a sliding contact at each of the plates senses that the plate has been moved to the unloading elevator, and the sliding contact is separated from the plate by the stamping carried on the plate, which senses thereby that the plate and the stamping upon it have both been transported to the unloading elevator. |
