Abstract

In unloading a press, it is desirable to provide automatic unloading without the need for operators, even in situations requiring a definite stacking order in containers located next to the press. To achieve this automatic unloading, extraction grippers and a carrier frame are provided which can be moved in three directions which are at right angles to each other by servo drives controlled by a continuous-path numerical control unit.
