Definitions

  • Tubular film bags are widely used for packaging food, for example chocolate bars. It is known to supply groups of such packs in a coherent manner, the separating cuts not being continuous in the transverse sealing seams, so that at least two connecting webs remain.
  • a device for producing such group packs is described in CH-PS 574 844. With the formation of the transverse sealing seam, a line of weakness is squeezed in the middle of this seam. The packs then go on a faster rotating conveyor belt. With a roller, they can be pressed selectively against the tape so that the pressed package is torn off the line of weakness just formed becomes.
  • this device cannot be used if the packaged products are sensitive to pressure.
  • the stress on the transverse seal just formed by tearing is problematic.
  • a device for cutting tapes from cellulose wadding is known with two counter-rotating drums.
  • One drum has a knife, the other a counter knife with two different profiles.
  • a continuous cutting cut or a cutting cut interrupted several times over its length can be carried out.
  • Fanfold folds with e.g. 100 sheets connected to one another via a perforation.
  • the present invention is based on the object of designing a device of the type mentioned at the outset in such a way that it is also suitable for pressure-sensitive packaged products and that the transverse sealing seams are not stressed when they are separated. This object is achieved by the combination of features of claim 1.
  • the pack according to the invention is described in claims 2-5.
  • the separation device shown has two superimposed, counter-rotating rollers 1 and 2, which are equipped with sealing jaws 3, 4, to which a hose 5 is fed by means of a conveyor belt or the like, not shown.
  • the tube 5 has been formed in a known manner on a tubular bag machine in such a way that it contains products 6, for example chocolate bars, at regular intervals from one another. Due to pressure and / or heat, the sealing jaws 3, 4 form a wide transverse sealing seam in the tube between two products 6 7, so that a series of interconnected hose packs 8 is formed.
  • the sealing jaw 3 is provided in the middle with a knife 9 and the sealing jaw 4 with a counter holder 10.
  • the knife 9 cuts through the transverse seam 7 as soon as it is formed in the longitudinal direction of the seam 7.
  • the cut 11 caused by the knife 9 can, for example, leave only two weak connecting webs 12 between the two halves of the seam 7. Instead, the knife 9 could also have a plurality of webs 12.
  • An endless conveyor belt 13 is arranged behind the pair of rollers 1, 2, on the upper run of which the connected hose packs 8 are conveyed further.
  • the speed v 2 of the band 13 is greater than the peripheral speed v 1 of the sealing jaws 3, 4 during the seam formation.
  • the rollers 1, 2 can also rotate non-uniformly.
  • FIG 2 a cross section through the rollers 1, 2 and sealing jaws 3, 4 is shown enlarged.
  • the counter-holder 10 has at least two, in the example shown frustoconical recesses 20 which can be moved by relative movement between the rollers 1, 2 in the area of the cutting edge 21 of the knife 9 or outside the area of this cutting edge 21.
  • the roller 2 is axially displaceable in two positions, for example by means of a cylinder unit 22 which engages via a lever 23 and a driver 24 in a groove 25 of the roller axis 26.
  • the rollers 1, 2 are connected to one another in a rotationally fixed manner in opposite directions via gear wheels 27, 28.
  • the knife 9 is zigzag-shaped.
  • the resulting section 11 is drawn in a greatly exaggerated manner for a better overview.
  • the recesses 20 of the counter-holder 10 are in the cutting area of the knife 9, so that the cut 11 does not go through there and the webs 12 remain (FIG. 4).
  • the cut 11 is continuous and the previous single bag or the previous group of bags is separated (FIG. 5).
  • FIG. 6 shows a variant in which the section 11 is straight but forms an acute angle with the transport direction A.
  • the webs 12 are always in a region of the cutting line 11, which forms an acute angle with the transport direction A.
  • the longitudinal sealing seam 30 is additionally indicated in FIG. 6.
  • FIGS. 7 and 8 show a further variant of the recesses 20 as lateral, triangular recesses 20 'in the counter-holder 10. In order to form a larger number of webs 12, the number of recesses is selected as required.
  • the roller 2 is adjustable by means of the cylinder 22 Number of revolutions shifted from the position shown in FIG. 4 into the position according to FIG. 5 and after one revolution back to the position according to FIG. 4.
  • the products 6 are not touched, so that pressure-sensitive products can also be processed with the device. Switching to a different number of connected bags is very easy.
  • the recesses 20 may also be expedient to design the recesses 20 other than frustoconical, e.g. pyramid-shaped or prism-shaped or as a lateral recess 20 'in the desired shape on the counter-holder 10.
