Definitions

  • the invention relates to a method and an apparatus for producing film bags, the V-shaped inserted gussets and a reclosure with a slider in a head-side filling opening.
  • the reclosure of the foil pouch consists of two profile strips and a slide coupling the profile strips.
  • One of the profile strips is connected to a front side of the film bag and the other profile strip after filling of the film bag connected to the other front side.
  • the initially flat foil bags are loaded into bag filling devices with filling material. The filling takes place at the head of the bag. The contents are introduced into an opening which is still present between the reclosure and a front side of the film bag. Thereafter, this opening is closed by a sealed seam.
  • Foil bags with the described features are used, inter alia, for packaging animal feed.
  • Foil bags with the features described are made DE 202 07 333 U1 known. Their production is complicated. Following the bag production, the reseals are applied in a downstream part of the plant. For this purpose, a film section of the already manufactured film bag is unfolded in the head region of the bag, placed a reclosure on the underlying film web and connected to this. Thereafter, the unfolded film section must be folded back and the missing sealing seams are attached.
  • the devices required for the application of reclosures must perform several steps and have a significant footprint. There is a need to integrate the application of reclosures while avoiding a downstream part of the plant in conventional bag-making process.
  • EP 1234773 and US Pat. No. 6,347,885 reveal a foil bag with Schieberausstanzungen.
  • the invention has for its object to provide a method in which the application of the reclosures during the continuous web advance of a flat film web takes place before the bag forming.
  • the invention is based on the idea of applying the reseals to the flat film web before the film web passes through a folding station, in which it is folded and gussets are formed.
  • the application of the reclosures according to the invention can be integrated into existing bag-making systems, the method according to the invention making use of the punching devices and folding devices already present in a bag-making machine.
  • the technical problem to be solved is that the reclosures during transport of the film web through the system, in particular in the Umfalt coupleden move, since the reclosures are initially connected only at the ends of the film web. There must be an opening between the profile strips of the reclosure and the film web so that the bags can be filled at the head end.
  • weakening lines are introduced into the flat film web transversely to the web longitudinal direction, which are arranged at the level of the window-shaped recesses and extend over the web width with the proviso that between the weakening lines and the window-shaped recesses in each case a 5 mm to 50 mm wide non-weakened film area remains.
  • the weakening lines are, for example, a perforation produced by punching or a weakening line produced by means of laser technology.
  • the film web is guided in the folding station in such a way that the edges of the folding tools rest against the non-weakened film areas between the perforation / weakening line and the recesses.
  • the folding of the film web into a tubular web is carried out using triangular Umfaltblechen, wherein the window-shaped punched-out are centered over the triangular plates.
  • the bags can be separated from the bag string in various ways.
  • An embodiment of the method according to the invention provides that the bags are separated by a separating cut of the bag string, wherein between the cutting edge and the adjacent weakening line remains a strip-shaped portion which covers the reclosure.
  • the strip can be used as a tamper-evident closure if the double-layered strip is sealed with a transverse sealing seam at its upper edge after the foil bag has been filled.
  • the top strip must be cut off, exposing the reclosure at the upper edge of the foil bag. If the sealing seam of the waste strip is undamaged, it is ensured that the foil bag has not previously been opened.
  • the bags can also be separated along the lines of weakness of the bag string by a tensile force is applied, for example by a train delay on the bag to be separated in the web longitudinal direction.
  • the bags are torn from the bag string along the line of weakness.
  • At the bottom end of the demolished foil bag remains a remnant, which can be used as a material for forming and sealing the bag bottom.
  • a further embodiment of the method according to the invention provides that the bags are separated by a separating cut of the bag string and between the cutting edge and the reclosure of a two-layer existing strip-shaped section remains, which covers the reclosure, and that the reclosure covering film layers with a Cutting knife are separated from the bag to expose the slider of the resealable.
  • supernatant film sections are separated after bag folding and welding by folding and cutting. This results in smooth film edges, which are not bevelled on the longitudinal sealing seams.
  • the plant shown comprises a unwinding station 1 for removing a flat film web 2 from a film roll 3, a punching device 4, a feeder 5 for prefastened reclosures 6, a folding station 7 with folding devices for double-layer folding of the film web 2 and for inserting V-shaped side folds, sealing stations 8 for the transverse sealing and longitudinal sealing of the folded material web and a station 9 for separating foil bags from the material web.
  • the punching device 4 window-shaped punching 10, which limit the upper end of the laterally formed side folds, as well Schieberausstanzungen 11 introduced ( Fig. 2 ).
  • the material web supplied resealments 6 consist of two superimposed and interconnected profile strips 12 and a slide 13, which overlaps the closing edges of the profile strip like a rider.
  • the prefastened reclosures 6 are placed on the flat film web 2 so that the slides 13 are located in the Schieberausstanzungen 11, and are then connected at the ends 14 with the film web 2.
  • the Fig. 2 shows the film web with reclosing reclosures 6 before the film web of the folding station 7 is supplied. In the folding station 7, the film web is folded into a double-layer material web and gussets are inserted.
  • the reclosures 6 are connected to a front surface of the bag by means of a sealed seam with the inclusion of the upper end of the gussets and the superimposed film layers are joined with further sealing seams 15 to form a bag-string 16 consisting of bag-shaped sections.
  • bags 17 are separated from the bag string.
  • the process product is in Fig. 3a shown.
  • the in Fig. 3a illustrated film bag 17 has two front sides, V-shaped inserted between the front side gussets 18 and a reclosure 6 in a head-side opening of the bag.
  • the reclosure 6 consists of two profile strips 12 and a slide 13 coupling the profile strips.
  • One of the profile strips 12 is connected to a front side of the bag.
  • the other profile strip can be connected after filling the bag with the other front side.
  • the superimposed film layers of the bag are connected to transverse and longitudinal sealing seams 15 at the bottom and along the edges of the side pleats 18, the longitudinal sealing seams 19 extending along the side pleats 18 extending from the bottom to the upper edge of the bag.
  • the reclosure 6 including its slider 13 is spaced from the upper edge of the bag within the bag.
  • a front side of the bag contains a pusher punching adapted to the dimension of the slider 13 11, in which the slider 13 is positioned prior to the first use of the bag.
  • the front sides of the film bag 17 have at the upper end of the bag on a reclosing occlusive strip-shaped portion 20 which is torn off along a arranged approximately at the level of the slider or below the slider line of weakness 21.
  • the weakening line 21 consists of a perforation produced by punching.
  • the line of weakness can also be produced by laser technology if a visually attractive tear-off edge is desired.
  • punch lines 22 which extend through the longitudinal sealing seams 19 to the outer edges of the bag.
  • the gussets 18 terminate below the perforation line 21.
  • the strip-shaped portion 20 can be separated along the perforation line 21 and the subsequent punching lines 22 of the film bag 17. In this case, the reclosure 6 is exposed.
  • the perforation line 21 is introduced into the flat material web and is in Fig. 2 shown. Of the Fig. 2 If one deduces that the perforation line 21 extend over the web width with the proviso that between the perforation and the window-shaped recesses 10 in each case a 5 mm to 50 mm wide, non-perforated film area 23 remains.
