In a destacking device comprising a stacking magazine (2), the respective lowest sheet of a stack (1) of metal sheets is destacked by way of a suction element (5, 15). This element can be moved upward and downward by way of a drive (6). At the end of the upward movement, the respective lowest metal sheet (4) of the stack (1) is gripped by suction power and pulled from the stack. A second suction element (5′, 15′) is provided, which can be moved upward and downward by way of a drive (6′) and by way of which the lowest sheet (4) of the stack (1) can be gripped at the end of the upward movement. The second suction element is driven so as to be leading with respect to the first suction element, so that the respective lowest sheet (4) of the stack (1) can first be pulled from the stack by the second suction element (5′), and subsequently by the first suction element (5). In this way, it becomes possible to destack thin sheets having a thickness of only 0.12 mm and a square shape without disruption. The stack is held magnetically in the stacking magazine, which facilitates destacking.
A destacking device, comprising a stacking magazine that is open on the bottom side and has holding means for a stack of metal sheets, and a pull-off device that is disposed beneath the stacking magazine and has a first suction element, which is driven in upward and downward movement, and in a reversal position thereof from the upward movement to the downward movement is positioned within the lower opening of the stacking magazine for gripping the respective lowest sheet of a stack of sheets by way of negative pressure and pulling the gripped sheet from the stack, characterized in that the pull-off device comprises an additional suction element which is driven in upward and downward movement so as to be leading in movement with respect to the first suction element, the lower opening of the stacking magazine is unobstructed by physical supports, and the holding means is implemented exclusively with magnets so that the stack can be held in the stacking magazine strictly magnetically, and the magnets are disposed on at least two opposing sides of the stacking magazine.

A method for destacking individual metal sheets from the bottom side of a sheet stack by gripping the respective lowest sheet by way of a first negative pressure suction element, which pulls the gripped metal sheet from the stack and deposits the same on a placement area, the stack being held in a stacking magazine that has an opening on the bottom side and has holding means, characterized in that the respective lowest sheet is partially detached from the stack by an additional suction element before being pulled off by the first suction element, the opening at the bottom of the stacking magazine is unobstructed, and the stack is held in the stacking magazine exclusively by magnetic holding means in the form of magnets.
