Crank drive for returning work pieces

Abstract

The invention relates to a mechanism for returning processed work pieces (7) from the output side to the loading side of a processing unit, which mechanism has a transfer mechanism (1) to transfer the work pieces (7) at the output side of the processing unit, a return mechanism (2) for transporting work pieces (7) delivered by the transfer mechanism (1) back to the loading side of the processing unit or to a further processing unit, and a lifting mechanism to lift the work pieces (7) to a return position located above the output position, whereby the lifting mechanism is located between the transfer mechanism (1) and the return mechanism (2) and has a lifting platform (3), with the lifting mechanism having a crank drive (4), by means of which the lifting platform (3) can be raised and lowered.
