Definitions

  • the present invention relates to the field of bags or sachets comprising complementary closure profiles suitable for allow successive openings and closings at will the user.
  • the present invention relates to the field of machines therefor, in particular machines adapted for training, automatic filling and closing of film-based packaging, in particular in thermoplastic material, comprising profiles of additional closure, for example male closure profiles and complementary female.
  • Such machines are often called FFS, corresponding with the initials of the English expression "Form, Fill and Seal Machine”.
  • Most of these machines include a forming collar which receives as input the film at the plan stage from an unwinder and provides the output of the film shaped into a tube, a filling chute which opens into this forming neck and consequently into said tube, means for conveying closure profiles and for fixing them on the film, longitudinal welding means for closing the tube longitudinally and means capable of sequentially generating a first transverse weld before a product is introduced into the tube through the filler neck, then a second transverse weld when the product has been introduced into the tube, to close a package around the latter.
  • the first attempt on the subject is described in documents US-A-4617683 and US-A-4655862. These documents dating back ten years have proposed two solutions to route the transverse profiles on the film, in the plan stage, before that it does not reach the forming neck.
  • the first solution is to laterally move sections of closure profiles using drive rollers placed laterally at the edge of the moving film, in combination with a displacement suction gripping head transverse.
  • the second solution consists in depositing profiles of closure on the film using a rotating barrel provided with retaining means pneumatic control.
  • Document US-A-4701361 has proposed, to form a film provided sequentially of complementary closure profiles, to realize, by extrusion, a tubular film provided with helical closure profiles, extruded or added, then cut the tubular film in a helix to obtain a strip provided with equi-distributed transverse profiles.
  • Document US-A-4878987 proposed, to reduce the length profiles deposited on the film, and therefore improve the positioning of these, to supply the profiles not using of a lateral reserve, as described in documents US-A-4617683 and US-A-4655862, but using two reserves of profiles arranged respectively on each side of the film intended to form the bags. So, each of the two sections of sections displaced on the film, respectively at from each lateral reserve, no longer covers the entire width of the film, but only half of it.
  • document US-A-5111643 proposes a complex installation comprising a chute which opens at the base of the forming neck for route the closure profiles carried by a support strip, and a discharge chute for the support strip.
  • EP-A-441 504 describes a packaging and a closure means corresponding to the preambles of claims 39 and 43.
  • a film-based packaging forming machine which comprises means for conveying closure profiles, transversely, on a film, formed in combination with a straight guide superimposed on the film, transverse to it, designed to position with precision at least one closing profile, transversely above the film, and a means for gripping the upstream end of the profile closure, capable of transverse displacement, along the guide, to route the closing profile in the latter by pulling on the end upstream of the closure profile.
  • the present invention now aims to improve the film-based packaging forming machines with profiles additional closure.
  • the present invention applies in particular, but not exclusively, to machines in which the closure means are conveyed on the film, transversely to the direction of it.
  • the invention preferably applies to training machines, automatic filling and closing of film-based packaging, type known per se comprising a forming collar which receives the film as input at the plan stage from an unwinder and outputs the film shaped into a tube, a filling spout which opens into this neck forming means and therefore in said tube, means for conveying closing means on the film and for fixing these on the film, longitudinal welding means for closing the tube longitudinally and means able to generate a first weld sequentially transverse before a product is introduced into the tube by the chute filling, then a second transverse weld when the product has been introduced into the tube, to close a package around the latter.
  • the conveying means are suitable for conveying transversely on the film, sections of closure means having at most one length of the order of half the width of the film, before it reaches the forming neck, and to fix the first one of the support webs on the film and means are also provided capable of fixing the second web support, on the internal wall of the film shaped into a sachet, after filling of it, when finishing the sachet.
  • the aforementioned biasing means can be formed of means temporary loads, for example in the form of a roller, a clamp or an equivalent means.
  • the two support webs of the closure means have different widths.
  • the present invention also relates to a method of forming packaging, the packaging thus obtained, and the closure means this effect.
  • the present invention also relates to a packaging according to the claim 39 and a closure means according to claim 43.
  • means are provided for conveying the closure means 300 transversely on the film F before that it does not reach the forming collar 20 and to fix this closure means 300 on film F.
  • the closure means 300 comprises two generally parallel support sails 310, 320 provided on their facing internal surfaces 311, 321, and set back from their lateral edges 315, 316, 325, 326 of at least one first longitudinal assembly 302 consisting of two complementary profiles 312, 322 linked respectively to the two support sails 310, 320 and a second longitudinal assembly 304 placed at a distance from the first assembly 302 according to the width of the sails supports 310, 320.
  • the second set 304 is also formed of two profiles complementary 314, 324 linked respectively to the two support webs 310, 320.
  • the second assembly 304 can be formed of a simple rib or buttress formed projecting longitudinally on the internal surface of one of the sails 310 or 320 or on each of these sails 310 and 320.
  • each of the support sails 310 and 320 carries a profile male and female profile.
  • one sails carries two male sections and the second veil carries two female profiles.
  • the means routing 10 are associated with means 160 for soliciting approximation, support sails 310, 320, between the two sets longitudinal 302, 304, so that the distance between the side edges of the two sails 315 and 325, 316 and 326 increases under the effect of this stress, by deformation of the sails 310, 320, as seen on the Figures 3 and 5.
  • the distance d1 separating the two longitudinal assemblies 302 and 304 is greater than the distance d2 defined at rest between the sails 310 and 320 by these assemblies 302 and 304. More again precisely this distance d1 is preferably between a times and five times the distance d2.
  • the distance d1 can be around 3mm, while d2 is around 2mm.
  • the routing means are also associated with two guides fixed parallel straight lines 170, 180 (orthogonal to the longitudinal axis of film scrolling) able to penetrate space respectively formed between each pair of lateral edges 315 and 325, 316 and 326 of support webs 310, 320, as seen in Figures 3 to 5.
  • guides 170, 180 can be the subject of many variations. As illustrated in the appended figures, these guides 170, 180 may have a rectangular, even oblong, cross section.
  • the biasing means 160 may consist of means temporary load formed by a roller 162 with axis 164 parallel to the axis longitudinal travel of the film, as illustrated in FIG. 3, or of any equivalent means, superimposed on closure means 300, immediately upstream of a guide 170, 180.
  • the height of the biasing means 160 relative to the support of the closure means 300 is adapted so that the means 160 stress and deform at least one of the sails 310, 320, between the two sets 302, 304.
  • the biasing means 160 may be formed of a clamp, the two of which jaws are likely to stress the support sails 310, 320, in approximation between the two longitudinal assemblies 302, 304, as we sketched it in 162, 162bis in FIG. 3.
  • Such welding 330 is carried out before routing the sections of closure means 300 on the film F. It can be produced downstream of the cutting station 206. However preferably welding 330 is carried out upstream of this cutting station 206, said cutting being carried out in the middle of the weld thus produced, so that a weld 330 thus forms a connection respectively between the rear ends of the sails of a first section and the front ends of the sails of a second section of means closing.
  • Such a weld 330 also offers the advantage of improving the tightness of the sachets and prohibit a complete withdrawal or separation of profiles 312, 322; 314, 324, when opening the sachets, which facilitates their subsequent re-engagement.
  • the widths d3 and d4 of the support sails projecting laterally by with respect to said sets 302 and 304 may be identical on the two sides of the sails.
  • widths d3 and d4 can be different from side to side, all by being identical for the two sails 310, 320, or by being different from one sail to another, in particular to facilitate the welding of the sails 310 and 320 on film.
  • the means 10 provided for routing the closing means 300, transversely, on film F, before it reaches the neck of forming 20, can in themselves be the subject of many variants.
  • routing means 10 conform to the provisions described in document FR-A-2 745 261.

  • the gripping means 150 can be formed by a suction head.
  • means are provided for transverse movement of the gripping means 150, synchronized with the displacement of film F.
