Method and device for stacking

摘要

A device and to a method for stacking plate-like products into a straight, cylindrical stack having an upper and a lower side and at least two side surfaces arranged at a distance from each other. In order to create a desired pretension in the stack already during stacking, which can even be maintained when individual products are added, the plate-like products are lifted against gravity from the bottom to the top into a stack nest, the products are held in the stack nest by applying a force on the side surfaces thereof to prevent dropping in the direction of gravity. While the force application is maintained, further products are added to the stack in the stack nest from the bottom side.

主权项

1. 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.
