Patent ID: 8870518

Claim:
A device for stacking plate-like products each with an upper side and an underside and at least two lateral surfaces located some distance apart into a straight, cylindrical stack, comprising: a lower deflection device; an upper deflection device; at least one traction mechanism of a traction mechanism drive that revolves between the lower and the upper deflection device configured to be brought into contact with each lateral surface of the plate-like products in the stack and applies a force to the lateral surfaces of the plate-like products in the stack to prevent dropping in a direction of the force of gravity; a back stop of the traction mechanism drive configured to prevent downward movement of the traction mechanism resting against the stack of the plate-like products; a movable counterholding unit configured to be brought into contact with the upper side of the stack, the counterholding unit comprising a weight movable along guides, wherein the counterholding unit applies a force that is evenly distributed throughout the stack; and a lifting arrangement for at least one plate-like product that can be moved in the direction of the underside of the stack and can be moved between a receiving position located below the lower deflection device of each traction mechanism drive and a delivery position located above the lower deflection device while the force applied by the at least one traction mechanism is maintained, so that the at least one plate-like product is held in the stack by the at least one traction mechanism when the at least one plate-like product is moved to the delivery position by the lifting arrangement.
