Definitions

  • the invention relates to a device for the Z-shaped folding of paper bags or the like around transverse folding lines with folding wheels which determine the folding edges, folding swords and the bags around folding bars which fold the folding swords.
  • a device for knocking in the side flaps of opened bottoms of cross-bottom bags with creasing wheels, folding swords that determine the folding lines and folding bars that fold in around the folding swords is known, for example, from DE-GMS 6 929 888.
  • the starting point of the invention is the finding that more compact, less storage space-requiring, more stable and more elegant stacks of cross-bottom bags can be formed when the area of the flat-lying bags between the end-side cross bottoms is folded in a Z-shape, so that the double-cross-folded bags also in have a height corresponding to the floor areas in their central area.
  • the object of the invention is therefore to provide a device for Z-shaped folding, in particular of cross-bottom bags, so that they can be stacked into compact, straight-edged stacks.
  • the device according to the invention makes it possible to fold the central regions of cross-bottom bags between the end bottoms in a Z-shape in time with the manufacture of the bags, so that these are shortened by almost half their length and can be stacked up to correspondingly smaller stable and compact stacks.
  • the shafts 3, 4, 5 and 6 are mounted between the side walls 1 and 2 of the machine frame. These shafts 3, 4, 5 and 6 carry conveyor belt rollers, not designated in any more detail, which are wrapped in endless conveyor belts 7, 8 and 9, 10, respectively. In the machine frame between the rotatable shafts 3, 4 and 5, 6 two further shafts 11 and 12 are superimposed, which support the upper scoring discs 13 and lower scoring discs 14, so that the individual bags transported by the conveyor belts 7, 8, 9, 10 15 received two pre-grooves 16 and 17 by the scoring discs 13 and 14.
  • the thus pre-grooved sacks 15 then arrive with their one half on a guide table 18 and are gripped in the area of their other half by conveyor belt pairs 19 and 20, the roles of which are carried on the one hand by the shafts 5 and 6 and on the other hand by two further shafts 21 and 22 will.
  • the shafts 21 and 22 are supported at their ends facing away from the wall 1 in a bracket 23, which is only shown in FIG. 3 for the sake of simplicity.
  • a folding sword 24 Arranged between the pair of conveyor belts 19 and the guide table 18 is a folding sword 24 which tapers out and has a vertically raised molded support strip 25 and a folded edge 26.
  • the sack is folded around this fold edge 26 in the region of its grooves 16 by a guide rod 27.
  • the folding rod 27 extends with reference to FIG. 1 and seen in the direction of transport from below the folding edge 26 and the folding sword 24 ascending towards the pair of conveyor belts 19.
  • the folding of the sack 15 'around the folding edge 26 in the area of the creasing 16 by the folding rod 27 is supported by the guide table 18, which, as shown in FIGS. 3 to 6, from a horizontal position to that in FIGS. 5 and 6 shown inclination is increasing.
  • the folding rod 27 is only attached at one end by means of a bracket 28 to a crossbar, not shown, which connects the walls 1 and 2 to one another.
  • FIG. 5 shows that the conveyor belt pairs 19 and 20 are covered by upper and lower housing parts 29 and 30.
  • a folding sword 35 is provided, which is fastened via brackets 36 and 37.
  • the folding sword 35 has a guide rod 38 which is fastened at its free end to the guide table 18 via a further holder 39, specifically underneath the same.
  • the sack area resting on the guide table 18 is guided on the one hand by the guide rod 38 with its groove 17 to the folding sword 35, and on the other hand is pressed onto the guide table 18 by a pressing rod 40, so that the sack is folded for the second time, namely around the crease 17.
  • This second folding process is supported by a folding rod 41, which presses the sack in the area of the grooves 17 around the folding edge of the folding sword 35, as shown in FIG. 6.
  • the folding rod 41 is fixedly connected at one end to the console 42 while it bifurcates at its other end. While one fork tine 41 'supports the folding process of the bag 15' by means of the folding sword 35, the tine 41 "of the folding bar 41 causes the sack part resting on the guide table 18 after the folding process has been completed onto a horizontal storage table 43 adjoining the guide table 18 is pressed down so that the folded sack can be removed on the one hand by the conveyor belt pair 32 and on the other hand by the discharge conveyor belt 44 adjoining the folding sword 35.
