- the gripping heads 35 are positioned relative to one another in such a way that a head image that is optimal for lifting is set depending on the dimensions of the part 12 to be unstacked.
- the Greifein unit drives 37 are controlled so that the gripping units 34 and thus the coupled gripping heads 35 are positioned and spaced relative to one another in the direction of passage 17, so that the positions of the gripping heads 35 in the direction of passage 17 for lifting off Are partially optimal.
- the track drives 68 are controlled, whereby the carrier 32, which are movably guided on the cross members 31 guide rails 69 are positio ned relative to each other, so that the distance of the gripping heads 35 can be changed in the transverse direction.
- the gripper head drives 44 are then activated so that the gripper heads 35 come in contact with the top of the part 12 to be lifted in the form of the suction heads.
- the suction heads are then evacuated, that is, a vacuum is generated, so that the suction heads are sucked onto the uppermost part 12.
- the part can be lifted off by simultaneously raising the gripping heads 35 or, preferably, by staggered starting up of different gripping heads, as is described in particular in DE 101 17 607 B4.
- the gripping heads 35 can each perform a movement with faster and slower movement phases during the lifting process, the movements of the different gripping heads 35 being asynchronous to one another, so that a continuously changing, undulating deformation of the gripping heads 35 held during the lifting process Part results, whereby the uppermost part is easier to detach from the rest of the stack of parts 16.
- the gripping heads 35 of the unstacking slides 26 move together into a trans port position.
- the longitudinal slide drives 51 are then activated, so that the destacking slides travel together to the conveyor belt 18.
- the unstacking slides which were previously located above the conveyor belt 18, are moved in the direction of the supply station.
- the carriage transverse drives 55 are activated, so that one of the unstacking carriage 26, in particular the unloaded one, can dodge in the transverse direction 29.
- the gripping heads 35 are moved downwards together to a discharge height and the part is deposited on the gripping heads 35 by introducing a pressure pulse. At the same time, an new unstacking of the uppermost part 12 by means of the unstacking slide 26 there.
- the adjustability of the gripping heads 35 to one another in the direction of travel and in the transverse direction 29 means that the gripping head image can be changed individually and adapted to different dimensions of parts to be unstacked.
