  • cross-stackers are usually designed to criss-cross several dozen or several hundred printed products per minute, which are delivered in a so-called scale flow from a printing press, and are usually transported further to a packaging station for further packaging.
  • Cross stackers are therefore designed for mass processing with large quantities per minute or hour. Cross stackers therefore have to work particularly reliably.
  • the invention has for its object to provide an apparatus and a method with which prefolded boxes can be reliably and economically stacked and processed.
  • a basic idea of the invention can be seen in the fact that the prefolded boxes are stacked crosswise or offset in accordance with the procedure in a cross-stacker.
  • a special hold-down device is provided.
  • the holding-down device according to the invention in particular on the stacking basket, a defined hold-down force can be applied to the upper folded cardboard in the stack and thus to the stack as a whole. This allows another exact stacking of the carton in the stacking basket.

  • a particularly preferred embodiment of the invention is that in the stacking basket, a basket bottom is arranged, which is adjustably mounted and driven between an upper lifting position, in which the stack can be transferred from the receiving element and a lower stroke position.
  • the receiving element above the stacking basket may be formed approximately like a rake.
  • a plurality of receiving elements can be arranged in a receiving basket above the stacking basket, which are operated alternately.
  • a first receiving element may be arranged in an upper receiving position in order to receive therein the first prefolded cartons from the shingled stream.
  • a second receiving element may be positioned in a lower receiving position, in which the second receiving element is a partial stack of rectified and stacked boxes on a lifting floor in the stacking basket passes.
  • the second receiving element can move up into the receiving position, while the first receiving element is moved in accordance with the stacking height forming by the supplied cardboard down in the direction of the lower receiving position and in a reject position.
  • the lifting floor of the stacking basket can be rotated by a rotary drive by 180 °, so that the next supplied partial stack of rectified boxes can be placed crosswise on the entire stack.
  • the lifting floor can be moved from an upper stroke position at the beginning of the stacking to a lower stroke position, in which the crosswise deposited total stack reaches its final height.
  • a particularly reliable hold down is achieved according to a further embodiment of the invention in that the first hold-down device has at least one hold-down arm, which is movable along the stack and presses with a predetermined hold-down force on the upper carton of the stack on the lifting floor.
  • the one or more hold-down arms of the first hold-down device may be movably mounted in a side region of the stacking basket or separately therefrom.
  • a compressed air device is basically possible, which generates a directed compressed air jet from the top of the folded-up cardboard on top of the stack.
  • the first hold-down device is preferably mounted co-rotating with the stacking basket.
  • a particularly reliable and compact stacking of pre-folded boxes is achieved according to a further embodiment of the invention in that in a transfer area between the feed device and the stacking basket, a second hold-down device is arranged, held down by which in stacking the prefolded cartons on the receiving element a respective upper carton is.
  • a second hold-down device With the second hold-down device, a hold-down force is exerted already on the receiving element when forming the stack and when transferring the carton from the feed device.
  • the second hold-down device has at least one rotationally mounted and driven roller body, on the outer circumference of which flexible hold-down elements are arranged.
  • the second hold-down device may comprise at least one roller body, on whose outer side flexible lamellae or rods are arranged. In the case of a feed from the right, the roller body would rotate in a clockwise direction, so that on the one hand the feed movement is supported by the flexible hold-down elements and the rotational movement of the roller body, and on the other hand a hold-down force is thereby exerted on the carton.
  • an ejector is provided on the stacking basket, through which the stack can be pushed out horizontally when reaching a final height of the stack on the lifting floor in the stacking basket, and that in the region of the ejector third hold-down means is arranged, through which for holding down the stack on the upper prefolded cardboard of the stack, a hold-down force can be applied.
  • the third hold-down device can be designed as desired, for example as a compressed air device.
  • the ejection device it is particularly preferred for the ejection device to have at least one horizontally movable slide on which at least one hold-down element is adjustably mounted between a hold-down position and a retracted position.
  • the at least one hold-down member may be formed rod-shaped.
  • the rod-shaped hold-down member can be adjusted via an actuating cylinder, in particular a pneumatic or hydraulic cylinder, between an approximately vertical retraction position and an approximately horizontal hold-down position.

  • the ejector takes over essentially only the displacement of the stack from the laterally open stacking basket. Once the slide of the ejector has reached its end position when ejecting, this moves back to its initial position in the stack basket. Thus, the third hold-down device again comes out of engagement with the stack.
  • the stack is stacked between a lower conveyor belt and an upper conveyor belt, the distance between the two conveyor belts being set so as to hold down the upper carton on the stack.

  • the apparatus described above can be used for stacking prefolded cartons.
  • the advantages described above can be achieved.
  • a preferred embodiment of the method according to the invention consists in that the feed device has a lower conveyor and an upper conveyor through which the prefolded cartons are pressed onto the lower conveyor in the shingled stream.
  • the shingled stream is already subjected to a holding-down force during the feeding of the prefolded cardboard boxes, in particular from a board machine. This prevents pre-folded boxes from building up in the course of the scale flow and lead to a malfunction.
  • the conveyors may be roller conveyors or preferably circulating conveyor belts.
  • the feed device can have a plurality of conveying devices arranged one behind the other, so that the continuous scale flow can be separated or separated into subsections by appropriate control of the conveying devices. From these then partial stacks are formed, each with the same orientation of the boxes. The partial stacks can be placed crosswise to the total stack. In the feed device, other separating devices may be provided.
  • a particularly reliable stacking of the pre-folded boxes is achieved according to a further preferred embodiment of the invention in that in a transition region between the feed device and the stacking basket, a second hold-down device is arranged, is held down by the stacking of the prefolded cartons on the receiving element a respective upper carton , Thus, even when stacking the unfolded cartons to a partial stack on the receiving element it is ensured that the upper carton does not unfold in an undesired manner.
