  • FIG. 18 shows a partial view of a further variant of the invention Device 1-18 for erecting / folding a folding box 2. This does not differ in its basic structure from the variant from Fig. 1, so that only the differences will be discussed here.
  • the device 1-18 comprises a folding station shown in the partial view 140.
  • This in turn includes those belonging to the swiveling means according to the invention Swivel arms 141.
  • Swivel arms 141 These are in a dashed contour 141 ' Position shown pivotable, whereby the folding walls 130 of the folding box 2nd from its upright, locked position to one - in Figure 18 by the dashed Contour 130 'shown - substantially parallel to the floor position be pivoted.
  • a shear force i.e. one parallel to the floor the folding box 2 force acting on the folding walls 130 to be pivoted Folding box 2 exercised.
  • the folding box 2 is of clamping means 142 in the area of its bottom captured.
  • the swivel arms 141 grip the folding walls 130 in their erected position from the outside. It is particularly advantageous that the Swivel arms 141 simultaneously or immediately before they fold the folding walls 130, the folding walls 130 provided from the bottom of the folding box 2 Release detent. It is therefore simultaneously or immediately before pivoting the folding walls 130 with the help of the swivel arms 141 a solution of the locked Folding walls 130 reached from their catch on the bottom of the folding box. This will a time saving when swiveling the folding walls into their parallel to the floor Position for folding the folding box 2 achieved.
  • the swivel arms 141 point when held in place by the clamping means 142 Folding box 2 a pivot axis running parallel to the folding axis of the folding walls 130 on.
  • the advantages here are that the pivoting movements of the Swivel arms 141 and the folding walls 130 run in the same direction. It there is therefore no tension between the in this embodiment Swivel arms 141 and those to be swiveled using the swivel arms 141 Folding walls 130.
  • the folding box is closed by the clamping means 142 held, the folding walls 130 by the Swivel arms 141 from their detent in the erected state in the Folding box 2 released and pivoted into a position parallel to the bottom of folding box 2, in which they are held by another detent. Subsequently the kink walls are kneeled. This is not done by one in FIG. 18 Second lifting device shown, the design of the lifting device 28th from Fig. 2 corresponds and is used only in reverse to the bring the upper edge of the folding box 2 to its bottom. Then the Folding box 2 released.
  • This function has the advantage that the articulated walls or the folding walls can be moved separately from each other. It can therefore no longer to the clamping known between the prior art Folding walls and articulated walls come. A folding box is folded therefore considerably more reliable than in known from the prior art Devices.
  • the folding boxes when folding or Raising led to be moved are also advantageous.
  • a movement of the folding or folding walls with the help of Gravity is not required so that work can be carried out reliably even if gravity, for example, due to an increased force required to move the folding or articulated walls - what force, for example, with a Clamping between folding and articulated walls can occur - not sufficient.
