ABSTRACT:
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 (1) 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 (2) 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 (1) comprises a transfer table with interspaced first supporting elements (4) for the workpieces. The lifting device comprises at least one lifting table (3, 3′, 3″) that, in turn, has interspaced second support elements (5), which can be upwardly guid through between the first support elements (4) of the transfer table. The lifting device comprises at least one drive unit (7, 8), which moves the at least one lifting table (3, 3′,3″) in a rotary motion from the transfer table upwards to the return position and back to the transfer table.
