Abstract
The invention pertains to an apparatus for destacking printed products such as books, brochures or book blocks for further processing, with said apparatus comprising a separating belt that takes hold of the respective product to be separated, a retaining device for preventing the residual stack from being transported further and a feed belt that is arranged upstream of the separating belt and feeds additional stacks to the separating area, wherein the retaining device comprises a movable element that is in contact with the stack and acts upon the residual stack with a force that feeds this residual stack onto the separating belt.
Claims19
An apparatus for sequentially separating individual printed products that are stacked in a height direction between top and bottom printed products, comprising:
- a first transport device that acts upon the respective sequential bottom printed product along a first feed direction (v) extending perpendicular to the stack height,
- a second transport device that is arranged upstream of the first transport device and feeds stacks thereto along said first fed direction, and
- a height-adjustable retaining device that holds back printed products above the bottom printed product from transport in the first feed direction and forms a passage with the first transport device for the respective bottom printed product to be separated from the stack as transported along the first feed direction by the first transport device,
- wherein the retaining device includes at least one movable contact element which contacts a surface of the stack with a force acting in a direction (d) toward the first transport device and perpendicular to the first feed direction (v).

- at least one movable contact element which contacts a surface of the stack with a force acting in a direction (d) toward the first transport device and perpendicular to the first feed direction (v),
- whereby said force urges the bottom printed product against the first transport device for separation and transport out of the stack while the retaining device holds back products above the bottom printed product.
