<p>A device at multi-platen presses (11) which with a loading elevator (12) by means of a pusher (14) simultaneously transfers a number of transport plates (15) loaded with stampings (17) to the press (11) which after the press operations are unloaded by means of an extractor (16) to an unloading elevator (13). The purpose is to prevent breakdowns and to automize the pushing-in and unloading of the transport plates, whereby it shall be able to stop the pushing-in or the unloading. These tasks have been solved in that the pusher (14) and/or the extractor (16) are provided with said means (22, 29), shaped as sensors of a number at least corresponding to the number of transport plates (15), which sensors are arranged to sense every separate transport plate regarding its pushing-in and withdrawal resistance resp., and that each sensor (22, 29) is arranged to activate an alarm device and/or a stop device, which stops the continued movement of the pusher or the extractor resp. when a certain force maximum is exceeded.</p> |
