Device for destacking cubic printed products

Abstract

A device for destacking books, brochures, or similar cubic printed products (), wherein said device comprises a separating belt () that is powered by a controllable drive and serves for the cyclic separation of the respective bottom printed product () from the stack (), lateral boundaries () that can be adjusted to the respective format and position the stack () on the separating belt (), a height-adjustable retaining element () that forms a passage for the respective printed product () to be separated, a support () in the infeed region of the separating belt () in order to support the rear edge of the printed product () lying on top of the bottom printed product during the separation of the bottom printed product (), and a feeding belt () that is arranged upstream of the separating belt () and serves for delivering the next stack () into the separating position. In order to reliably and flawlessly separate, in particular, thick book blocks with a small format from high stacks, the destacking device () features at least one supporting element () that is arranged at a defined distance behind the stack () and can be moved out of the transport path during the delivery of the next stack (). The supporting element automatically moves out of the transport path during the delivery of the next stack ().
