  • Patent number: 8573920
    Abstract: A stacking device for print products that includes a table to receive the print products such that the print products form a stack. The device also includes at least two ejector elements arrangeable against the stack to push the stack in an ejection direction away from the table. The stacking devices further includes at least two drive elements operatively connected, respectively, with the at least two ejector elements so that the at least two ejector elements move independent of one another.

  • Patent number: 8235436
    Abstract: A bundle gripper for a palletizing machine for picking up respectively at least one bundle and depositing the bundle on a pallet. The bundle gripper including a frame, an adjustable end stop, and at least one gripper finger such that the gripper finger has a front end and is adjustable on the frame. The gripper finger being movable between a first position and a second position. The bundle gripper also including a hold-down clamp coupled to the frame and positioned against the end stop for clamping the bundle against the gripper finger such that a distance between the end stop and the front end of the gripper finger in the second position is changeable to adapt to different lengths of the bundles. The end stop and the gripper finger are each movable to change the distance and the hold-down clamp is correspondingly adjustable to accommodate different lengths of the bundles.

  • Patent number: 8152434
    Abstract: An infeed station has a stack feeder and a first and second chamber, which can each receive stacks from the stack feeder. The stacks can be conveyed in the chambers and can be transferred to a stack gripper with the conveyors assigned to the first chamber and the second chamber. First centering units serve to center the stacks in the first chamber, and second centering units serve to center the stacks in the second chamber. Third conveyors are arranged between the first and second conveyors. The first and second centering units can be shifted relative to each other so that the third conveyors are positioned in the first or second chamber, and the chamber with the third conveyors is much wider than the other chamber. The infeed station can be changed between double infeed with parallel processing of two stacks and single infeed with processing of only one stack of relatively great width at a time.
