  • the present invention relates to a method for forming bag stacks from bags, to an apparatus for carrying out one of these methods and to an apparatus for producing flat bags.
  • Stacking bags is a long-standing problem area. Also DE 35 24 203 C2 deals among other things with the associated problems. According to the state of the art, flat-bottomed bags are produced by depositing bags directly from a delivery cylinder with the trays just formed, perpendicular to a tray. This shows the opening of the bag upwards. The stacks are thus formed by the bags are strung together. They touch each other with their front pages. However, this method has proved disadvantageous as the length of the bags increases. Therefore, the present invention has set itself the goal of proposing a bag-stacking method in which bag stacks are formed in a more reliable manner.
  • the object of the invention is achieved by the features of the characterizing part of claim 1.
  • a belt-tongs system transports the bags up to the storage rack and aligns in a suitable manner.
  • the belt-tongs system rotates the bag by 180 °, so that the front side faces the stack at the end of the transport with the belt-tongs system, without the belt-tongs system the stack turned away.
  • the method according to the invention has proved to be particularly advantageous in connection with flat bags.
  • Fig. 1 shows a flat and side-folding bag machine 1 with a folding and transport cylinder 2, on which a part of Pinchboden bag making is made.
  • a folding and transport cylinder 2 has a plurality of pliers 3, of which bags or semi-finished bag can be added.
  • the rotation of the folding and transporting cylinder 2 about its axis 4 leads these bags or bag semi-finished products to different processing stations and also past the upper folding cylinder (folding blade) 5.
  • the exact configuration of such Bag machine 1 which indeed includes a machine frame 6, but is not the subject of the present patent application. Rather, it is at this point to show that the bags are placed on a bag tray 7, wherein the bags 9 line up in their vertical extent there.
  • the bags 9 are prevented from tipping over by the bag support 8.
  • the result of this usual measure are very unstably stacked bags, which are also exposed to a harmful burden shortly after their bonding.
  • FIG. 2 shows a bagging machine 1, which is equipped with a device according to the invention.
  • the bagging machine 1 again has a folding and transporting cylinder 2 and an upper folding cylinder (folding blade) 5.
  • the bags 9 are brought from the discharge 15 to leave the folding and transporting cylinder 2 and are transferred to a double belt conveyor 10a. From this, the bags 9 are guided to a switch 11, which decides whether the bags 9 are transferred to the double belt conveyor 10b or the double belt conveyor 10c.
  • the double belt conveyor 10b feeds an upper tray, while double belt conveyor 10c feeds a lower tray. After passing through these double belt conveyors 10b and 10c, the bags pass to transfer stations 12b, c, from which they are respectively transferred to the associated belt-tongs system 13b or c.
  • the said belts 13b and 13c run on the transport rollers 14.
  • the two belt-tongs systems 13b and 13c are respectively provided with grippers or tongs 16 which carry the bags 9 with them.
  • the bags 9 are rotated by 180 ° by the belt-tongs system with respect to the storage locations 17b and 17c. In the present case, this rotation contributes to the fact that the side of the newly added to the stack front of each bag on which the Pinchfaltung is placed on the front of the already deposited bag meets, which just has no pinch fold and which is so smooth ,
  • Figure 2 shows a plurality of bags 9 at the storage locations 17.
  • the corresponding bag stack in the direction of arrow 18 are transported away from the respective storage location.
  • the belt-tongs system 13b or 13c is activated, and the switch 11 supplies the bags 9 via the respective double-belt conveyors 10b and 10c. In this way, enough time remains for the Ausschleusungsvorgang the corresponding bag stack of the bag depositories 17.
  • FIG. 3 shows a diagram of a flat bag 9 with a pinch bottom, which has a folded-back bottom area 19, which is folded back onto a front side 21 and connected thereto by gluing.
  • the distance of the folded-back flap 19 from the front 21 was exaggerated.
  • the side 21 opposite is the smooth side 20, on which no bottom part 19 has been folded back.
  • FIG. 4 once again shows how such pouches 9 can be stacked in an advantageous embodiment of the invention.
  • the bags are stacked on each other while the front side 21, with the folded-back part of the bottom 19, faces the smooth side 20 of the already deposited bags.
  • the bag 9, which is being stored, is still being transported in the direction z.
  • components of movement in the vertical direction x are also added.
