Definitions

  • the invention relates to a device and method for stacking, i.e. for dividing a stack of sheets into giant ones Number of sheets. Paper processing is often done after manufacturing of single sheets, stacking and palletizing these single sheets. at Further processing of these single sheets must then be done individually Giants are generated that are as precise as possible a specified number of sheets Number of sheets included. Usual ream sizes are, for example in the range of 50 to 500 sheets.
  • this method has the disadvantage that it is used to determine the correct one the height of the paper stack is necessary on the one hand, a high To bring surface pressure into the paper stack on the puncture side, on the other hand with the increasing surface pressure the danger there is at least one of the leaves in the puncture area when piercing to damage. Damage does not only count here Kink the paper if at the puncture site instead of the space a sheet is hit between two sheets, but even if the surface of one of the leaves, for example, by Wiping or scratching marks, their quality is impaired.
  • GB 772 679 describes the processing of sheet stacks in one Printing press, in which when a stack is emptied a plate underneath brought the old stack, placed a new stack underneath and then the plate is removed.
  • DE 26 39 676 A1 describes a method and a device for loading a circular stack feeder, to which described is that when a pallet is emptied a signal is triggered when there is no longer a complete stack of sheets on the pallet. Then a pallet change takes place. With this facility, none exactly measured stack formed, but the final state is one scaled sheet position.
  • US 4 955 854 describes a device for dividing a stack into a number of individual stacks, in which the division up to complete emptying of the entire stack is continued and then one Batch change takes place.
