Device for destacking one or more stacks of flexible flat structures, in particular of sheets of paper or printed products

摘要

The stack (12) which is to be destacked and is formed by rectangular products (13), for example folded or unfolded sheets of paper or printed products, lies on a stack support in the form of an endless roller grid (1) circulating in the direction of arrow A. The individual rollers (2), running parallel to one another and with a mutual spacing, of the roller grid (1) are inclined with respect to the direction of movement (A) of the roller grid (1), whilst the stack (12) is aligned with this direction of movement (A). In the region of the corner, facing the arriving rollers (2), of the stack (12) a separating element (14) is arranged below the roller grid (1). This separating element grasps the corner of the respective lowermost product (13) and draws said corner through between two rollers (2). The following roller then runs over this downwardly bent corner, so that the following rollers can then run in between this lowermost product (13) and the stack (12). The lowermost product (13) is thereby detached and comes to rest on a conveyor belt (20) which transports the released product away in the direction of arrow B which is directed opposite to the direction of movement (A) of the roller grid (1).
