The invention relates to a device for returning machined workpieces from the delivery side of a first machining unit to the feeding side of the first or of another machining unit. The inventive device comprises the following: a transfer device () for transferring the machined workpieces to the delivery side of the first machining unit; a lifting device for lifting the workpieces, which are delivered by the transfer unit, into a return position located above the transfer unit, and; a return device () for conveying the workpieces, which are delivered by the lifting device, back to the feeding side of the first or the other machining unit. The transfer device () comprises a transfer table with interspaced first supporting elements () for the workpieces. The lifting device comprises at least one lifting table () that, in turn, has interspaced second support elements (), which can be upwardly guid through between the first support elements () of the transfer table. The lifting device comprises at least one drive unit (), which moves the at least one lifting table () in a rotary motion from the transfer table upwards to the return position and back to the transfer table.

Device for returning workpieces

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

Crank drive for returning work pieces

A feed and stacking device for slab-shaped workpieces has a rigid frame which is pivotally mounted on a base stand for movement between a horizontal position and a raised position. A support bar is movable along the length of the frame and carries a plurality of vacuum operated pick-up devices for transferring a workpiece from a stack to a processing device or vice versa.
