  • the smooth and essentially continuous collecting box floor used in the prior art is replaced by retractable and extendable supporting elements, which instead of the previous collection box floor now carry the sheets or the stack to be formed from the sheets and thus the task of supporting means for supporting or to store the sheets or the stack.
  • the stacking area be adapted to the height of the stack to be formed from the sheets, but also the bottom of the stacking area becomes flexible in terms of format, since only the actually required supporting elements have to be used to support the stack, which is particularly the case when using lateral stacking Attacks is beneficial.
  • Another advantage of the invention is that upon removal of the finished stack from the stack formation area, the resulting gap behind this stack is filled by extending the support elements in their upper end position again.
  • an essentially automatically adjusting stack deposit is proposed by means of the invention If appropriate, it can also be designed to be multi-functional and has per support or per individual collection box a support device which is formed from a multiplicity of support elements movably mounted between an upper and a lower end position.
  • At least some of the support elements preferably have a rod-shaped or pin-shaped body and are mounted so as to be movable substantially in the direction of the longitudinal extent of their rod-shaped or pin-shaped body.
  • At least some of the support elements have a wider, preferably flat, head relative to a remaining section, with which these support elements can be brought into a particularly flat contact with the underside of the lowermost flat part of a stack.
  • the support members are movable between an upper position and a lower position, and the distance between the upper position and the lower position is sized or adjustable in response to a predetermined maximum height of the stack to be formed from the flat parts.

  • the pins 22 serve to receive the incoming from the conveyor 2 sheets and thus take over a support function for storing the sheets for the formation of a stack. Therefore, the pins 22 may also be referred to as support elements. While the pins 22 shown in the figures consist only of a rod or pin-shaped body, it is for example alternative also conceivable to provide the pins with a relative to the rod or pin-shaped body wider, preferably flat, head or stamp to form a larger surface support for the sheets, which is not shown in the figures.
  • the pins 22 are movably mounted in the vertical direction between an upper end position and a lower end position. In the upper end position, the pins 22 are extended furthest. In the Fig. 1 visible pins 22 are in their upper end position. In the lower end position, however, the pins are retracted. In the embodiments shown in the figures, the pins 22 are in its lower end position with its upper front end or head at height and in alignment with the bottom 18 and thus substantially completely withdrawn into the housing 20 down or disappeared in this , In particular, when the pins 22 are movably mounted in the housing 20 so that they are retracted into a lower position below the bottom 18 in the housing 20 and thus below the bottom 18, the effective lower end position is alternatively formed by the bottom 18.
