Definitions

  • the invention relates to a method and an apparatus for producing bag packages.
  • Bag packs in which, for example, foods, such as milk powder or flour, can be stored are usually made of a sealable material, have a base suitable as a base, in particular a block bottom, and an angular, preferably rectangular cross-section. To improve the stability of these bag packages, it is common to reinforce the longitudinal edges.
  • edge reinforcements prevent deformation of the side walls and thus ensure a high dimensional stability of the bag package.
  • the reinforcements consist for example of sealing seams which are produced by means of heat sealing so that they do not have to fulfill any sealing function.
  • tubular bag machines form the bag packages of rectangular cross-section from a packaging material web.
  • the packaging material web is folded so that a tube is formed.
  • the edges are shaped and sealed, so that the desired rectangular cross section is formed and the bag package has the desired stability.
  • the abutting edges are welded together, whereby the longitudinal seam or the longitudinal sealing seam is formed.
  • DE-GM 18 07 453 describes an apparatus for producing bag packages.
  • the edge strips adapted to the reduced bag cross-section mainly on both sides of the bag longitudinal edge, are longitudinally displaceable and spring-mounted.
  • Below the bag bottom is a press plate with this hinged and swung to the bag walls heating plates pressed.
  • the side heating plates are hinged and shaped so as to give the desired Kantenversch conductedung on the bottom and at the side edges in cooperation with the edge strips located inside the bag.
  • a disadvantage of known methods and devices is that in the area behind the forming tube, in which the edges are formed and sealed, machine height is required.
  • the known from the prior art method for producing sealed-edge bag packs provides that a Hüllstoffschlauch is formed from a packaging material web wherein the sealing seams are formed prior to forming the Hüllstoffschlauches on the packaging material web.
  • the apparatus for producing bag packages comprises a folding station for forming folds; a sealing station for sealing the formed pleats, a packaging material driving station, and a forming station for forming the wrapping tube, the folding station and the sealing station being arranged to form the sealing seams prior to forming the wrapping tube.
  • the folds are formed at the point in the packaging material web, at which later the edges are provided. Since the sealing seams applied to the flat packaging material web are not required in this area Maschinenh6h ⁇ .
  • folding plates or sheet metal plates are provided for forming the folds in the packaging material web, wherein the packaging material web is guided on the underside of the first folding plate and on the upper side of the at least second folding plate.
  • These metal sheets are easy to replace.
  • the device can be designed for different bag sizes. Depending on whether the subsequent longitudinal sealing seam, which is welded in forming the Hüllstoffschlauches, is located in the region of an edge, three or four folds are formed.
  • an outlet roller is provided between the folding station and the sealing station, with which the packaging material is diverted at right angles. This ensures that a seam seal with uniform seam width is to be made.
  • the outlet roller causes the folds to be bent sharp-edged and can therefore be sealed afterwards with a constant seam width.
  • the forming station has a forming tube and a forming shoulder, which are already known from conventional tubular bag machines.
  • An arranged below the forming shoulder guide plate ensures that the edge seals get the desired orientation.
  • the sealing station consists of at least one heatable sealing jaw and an anvil jaw.
  • the at least one sealing jaw is typically disposed below the packaging material web and the anvil jaw at the top thereof. It is advantageous if the Amb thoroughlybacke is also heated.
  • the lower sealing jaw is pneumatically driven, it is possible to immediately remove the heated sealing jaw when the packaging material is at a standstill in order to prevent thermal damage.
  • the sealing pressure is set via the lower jaws with compression springs.
  • FIG. 1 a shows a bag pack, designated in its entirety by the reference numeral 10.
  • the edges of the bag pack 10 have sealing seams 12.
  • the sealing seams 12 ensure the stability of the bag package 10.
  • One of the sealing seams 12 represents the longitudinal seam.
  • FIG. 1b shows the bag pack 10 with a centrally extending longitudinal seam 11 and four sealing seams 12 forming the edges of the bag pack 10.
  • FIG. 2 shows a sealing station 20 in a schematic representation.
  • the sealing station 20 comprises a heatable sealing jaw 22 and above it an anvil jaw 24. Between the sealing jaw 22 and the anvil jaw 24, a packaging material web 26 is carried out by means of two driven rolling rolls 28, thereby sealing the folds already formed in the packaging material web 26.
  • the sealing jaw 22 is pneumatically driven in the direction of a double arrow 30.
  • the sealing pressure is adjusted by a compression spring 32.
  • sheet metal plates 40 are shown for forming the folds. Between these metal plates 40, a packaging material web 42 is performed to form the folds. In this case, the packaging material web 42 is diverted via a roller 43.
  • the metal plates 40 cause folds 44 are formed in the packaging material web 42 at predetermined locations.
  • Figure 4 shows a section along the line IV - IV of Figure 3.
  • the metal plates 40 can be seen.
  • the packaging material web 42 which has folds 44 in predetermined areas.
  • FIG. 5 shows a device according to the invention for producing bag packs, a so-called tubular bag machine 50.
  • This comprises a folding station 52, a sealing station 54, a forming station 56 and a driven pressure roller pair 58 as packaging material drive station.
  • a packaging material web 60 is transported for processing.
  • Arrows 62 indicate the direction of the packaging material web 60.
  • the packaging material web 60 is first diverted via a deflection roller 64 and guided down to an inlet roller 66. Subsequently, the packaging material web 60 between sheet metal plates 68 is performed to form the folds in the packaging material web 60.
  • the sheet metal plates 68 correspond to the sheet metal plates 40 from FIG. 4.
  • An outlet roller 70 redirects the packaging material web 60 before it is passed through the sealing station 54.
  • the sealing station 54 comprises an anvil jaw 72 and sealing jaws 74 which are disposed in the region of the folds in the packaging material web 60, so that these folds are sealed.
  • the packaging material web 60 which now has sealed seams 76, via the driven Pressure roller pair 58 to the forming station 56 further transported.
  • the forming station 56 includes a forming shoulder 78 and a forming tube 80.
  • an envelope tube is formed from the packaging web 60.
  • the abutting edges of the packaging material web 60 are welded to a longitudinal seam sealing jaw 82.
  • the packaging material conveyor belts 84 For transporting the packaging material web 60 or the Hüllstoffschlauches serve two packaging material conveyor belts 84. With cross-seaming jaws 86, the transverse seams are sealed.
  • FIG. 6 shows a section along the line VI - VI from FIG. 5.
  • the first sheet metal plates 68A are arranged above the second sheet metal plates 68B in FIG. 6 so that the flat packaging material web 60 can be made between.
  • FIG. 7 shows a section along the line VII - VII from FIG. 5. Again, the first sheet plates 68A and the second sheet metal plates 68B and the packaging material web 60 passed between them are shown. In this illustration, it can be seen that the second metal sheets 68B are now above the first metal sheets 68A. The position of the first metal plates 68A to the position of the second metal plates 68B is thus changed as compared with that in FIG.
  • first metal plates 68A are aligned with the second metal plates 68B so that the first metal plates 68A are above the second metal plates 68B in the area shown in FIG. 6 and the first metal plates 68A are below the second metal plates 68B in the area shown in FIG.
  • the metal plates 68 thus do not run parallel to each other.
  • the first metal plates 68A are located above the second metal plates 68B.
  • the second metal plates 68B are now aligned or inclined relative to the first metal plates 68A so that they are located above the first metal plates 68a in the rear region relative to the transport direction 62. This causes the guided between the metal sheets 68 packaging material web 60 is folded at designated locations.
  • the pleats are then sealed in the sealing station 54 and later form the sealed edges or seams 76 of the bag package.
