Definitions

  • the invention relates to a folding apparatus with at least one transverse folding device which can be acted upon and unloaded by tape guides and is designed as a compression folding device, which has a compression chess flanked on the input side by two outer rollers which cooperate with a central fixed roller to form transport gaps and are assigned to the tape guides, and by one on the central one Roller running belt set is enforced.
  • outlet-side outer roller can be swiveled from the middle roller while lifting the outlet-side transport gap and the upsetting shaft can be raised with its entrance via the inlet-side transport plane of the belt set running over the middle roller.
  • the measures ensure that the upsetting device designed in this way can optionally be activated or passivated and, in the passivated state, can be passed through by the products arriving via the belt guide without a folding process.
  • the measures according to the invention therefore advantageously offer the possibility of, for example, laying out cross-folded products only once behind a second cross-folding device.
  • outlet-side outer roller and the compression shaft are accommodated on bearing plates pivotable about the axis of the inlet-side outer roller.
  • the entire assembly can be adjusted in a simple manner by means of an actuator acting on the end shields, the end positions being able to be appropriately secured by stops.
  • the inlet of the compression shaft can be closed when the transport gap on the outlet side is lifted by tongues which can be releasably received on the pivotable end shields and bridging the two outer rollers.
  • These tongues form practically stationary guide devices which prevent the products from dodging in the area between the two outer rollers which are spaced apart from one another.
  • the outer roller on the outlet side is followed by a deflecting roller which can be pivoted with it and is also accommodated on the end shields, which engages in the outlet-side belt guide with the formation of a belt kink and its belt-side distance from the adjacent outer roller at least the maximum depth of the upsetting shaft corresponds.
  • the folding apparatus on which FIGS. 1 and 2 are based consists, in a manner known per se, of a first transverse folding device, which is formed here by a flap folding device 1, and a second transverse folding device connected to it by a band guide 2, which is formed by an upsetting folding device 3.
  • the upset folding device 3 can be connected via a band guide 4 running out of it to a product delivery (not shown here in greater detail) or a further folding device for producing a longitudinal or transverse fold.
  • the once cross-folded products are lifted out of the folding flaps of the flap folding device 1 by lift-outs and introduced into the band guide 2, which is designed here in two parts in order to achieve a delay in the products.
  • the upsetting device 3 consists of a compression shaft 5 which practically forms a dead end for the products P arriving via the belt guide 2 and of three rolls 6, 7, 8 which are driven at the same circumferential speed and which are set against one another in the activated position on which FIG. 1 is based so that which are offset from one another on the circumference of the middle roller 6 by approximately 90 ° , the transport gaps 9 or 10 opposite the input cross section of the upsetting shaft 5 and a middle roller 6 forming the upsetting shaft entrance of the two outer rollers 7 and 8, which are circumferentially spaced from each other, result in limited passage window 11.
  • rollers 6 to 8 are driven so that the transport gap 9 facing the first transverse folding device acts as a feed gap into which the transport plane of the belt guide 2 enters, and that the second transport gap 10 acts as a pull-out gap against which the belt guide 4 connects.
  • the two outer rollers 7, 8 simultaneously form the deflecting rollers of the upper belt sets 12a and 12b, which interact to form the belt guides 2 and 4 with a lower belt set 13, which runs through the middle roller 6 and passes through the compression folding device 3, the two outer ones In the activated position on which FIG. 1 is based, rollers 7, 8 can be adjusted to adapt the clear width of the transport gaps 9, 10 to different product thicknesses compared to the central, stationary roller 6.
  • the compression shaft 5, which is continuous over the entire width of the machine, is inclined upwards relative to the transport plane of the belt guide 2 entering the transport gap 9, starting from the passage window 11 forming its entrance.
  • a further adaptation to the different conditions that result in products of different thickness is possible by pivoting or displacing the upsetting shaft 5.
  • this can simply be accommodated on a pivotable or adjustable crossbar 14.
  • the upsetting shaft 5 results as the interior of a configuration which is approximately U-shaped in longitudinal section towards the middle roller 6 and which is formed by U-shaped, spaced-apart, parallel guide walls extending over the entire machine width and bridging the distance between these guide walls and the depth of the upsetting shaft, which is therefore adjustable and adjustable and also extends over the entire machine width, is formed.
  • the guide walls can be tapered and bent to form a V-shaped inlet and outlet area opening towards the middle roller 6.
  • the upset folding device 3 In the activated position of the upset folding device 3 on which Figure 1 is based, the products P drawn in once through the inlet-side transport gap 9 shoot with their front edge into the upset shaft 5 and are pulled off with the formation of a second transverse fold over the outlet-side transport gap 10, so that the tape guide 4 twice cross-folded products P 'leads.
  • the upset folding device 3 In order to be able to produce cross-folded products only once and to lay them out behind the upset folding device 3 by means of the band guide 4, the upset folding device 3 can be brought into the passivated position on which FIG. 2 is based, in which the once folded products P shoot past the upsetting shaft 5.
  • the outer roller 8 on the outlet side and the upsetting shaft 5 are received on common bearing plates 16 which can be pivoted about the axis 15 of the outer roller 7 on the inlet side and which are pivoted up from the position on which FIG. 1 is based to passivate the upset folding device 3 to the position on which FIG. 2 is based , in which the outlet-side outer roller 8 is lifted so far from the stationary middle roller 6 that there is no longer any transport gap between these two rollers, that is to say the outlet-side transport gap 10 is canceled, and in which the compression shaft 5 is raised so far, that its input 11 is located above the transport plane of the belt guide 2 entering the transport gap 9 on the inlet side.
  • the pivoting position of the pivotable assembly which is accommodated on the end shields 16 is selected in the passive position on which FIG. 2 is based so that the belt set 13 traveling underneath the compression shaft entrance 11 is not deflected in the region of the middle roller 6; H. that the transport plane of the belt guide 2 extends without deflection in the area of the middle roller 6 under the two outer rollers 7, 8.
  • the adjustable assembly can be adjusted by actuators 17 acting on the end shields 16, for example in the form of a cylinder-piston unit or a spindle drive etc.
  • the end positions on which FIGS. 1 and 2 are based can be defined by stops 18 and 19 which cooperate with the end shields 16.
  • the upsetting shaft entrance 11 in the passivated position on which FIG. 2 is based can be closed by a guide device 20 bridging the distance between the two outer rollers 7, 8 in order to accomplish a further securing.
  • This can simply be designed in the form of a rake consisting of tongues lying next to one another and releasably fixable on the pivotable end shields 16.
  • a deflection roll 21 is provided downstream of the outer roll 8 on the outside, which is received together with the adjacent outside roll 8 and the upsetting shaft 5 on the end plates 16 and into which the upsetting device 3 leaving band guide 4 engages to form a band kink 22, by means of which the conveyed products are stabilized.
  • the deflection roller 21 In the passivated position on which FIG. 2 is based, in which the products P, once folded, are to simply pass through the passivated upsetting device 3, is deflected by the deflection roller 21 in cooperation with a downstream stationary deflection roller 23 and the two outer rollers 7, 8 of the upsetting folding device 3 only a comparatively flat ribbon bend is formed.
  • the distance of the deflecting roller 21 from the adjacent outer roller 8 of the upset folding device 3 is chosen so that the length of the through Deflection roller 21 and the adjacent outer roller 8 limited band guide section at least the depth of the upsetting shaft 5 than at least the maximum processable format. This ensures that, in the case of upsetting operation, the products which are folded twice here in the region of the hinge 22 are only deflected when they have already left the upsetting device 3.
  • the set of belts 13 passing through the upset folding device 3 and running on the middle roll 6, as well as the cooperating upper and lower belt sets 12a, 12b on the inlet and outlet sides run over pivotably mounted compensating rollers 24 which, in addition to the gap adjustment, also enable the above-described change in position of the pivotable assembly.
  • the rollers 6, 7, 8 of the upset folding device 3, which are driven at the same speed, can be driven by means of a toothed belt toothed on both sides, which runs via pinions attached to the side of the rollers.
  • the belt sets 12a and 12b receive their drive via the rollers 7, 8 of the edging folding device 3, which act as deflection rolls.
  • the driving of the rolls of the edging folding device 9 3 is therefore in operation both in the activated and in the passivated position, so that the drive of the Volume set 13 can be derived from this.
