Definitions

  • the present invention relates to the field of bags or sachets comprising complementary closure profiles adapted to allow successive openings and closings at will of the user.
  • the present invention relates to the field of machines for this purpose, in particular machines suitable for the formation, filling and automatic closure of film-based packaging, in particular of thermoplastic material, comprising complementary closure profiles, by example of complementary male and female closure profiles.
  • Such machines are often called FFS, corresponding to the initials of the English expression "Form, Fill and Seal Machine”.
  • Most of these machines include a forming neck which receives the film in the planar state from an unwinder and provides the film-shaped tube as output, a filling chute which opens into this forming neck and by Consequently in said tube, means for conveying closure profiles and for fixing them to the film, longitudinal welding means for closing the tube longitudinally and means capable of sequentially generating a first transverse weld before a product either introduced into the tube by 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 in this area is described in documents US-A-4617683 and US-A-4655862. These documents, which date back ten years, proposed two solutions for conveying the transverse profiles on the film, in the planar state, before it reaches the forming neck.
  • the first solution consists in moving laterally sections of closure profiles using drive rollers placed laterally at the edge of the moving film, in combination with a suction gripping head with transverse displacement.
  • the second solution consists in depositing closure profiles on the film using a rotary barrel provided with pneumatically controlled temporary retaining means.
  • the first of these solutions consists in driving the closure profiles, using an endless belt on a stirrup superimposed on the film and pivoting 180 °, to turn the closure profiles on said film.
  • the profiles are routed initially, relief directed towards the film, on the stirrup, then are turned over, relief directed opposite the film, to be fixed on the latter.
  • the second solution consists in conveying the profiles transversely on a shoe superimposed on the film and then lowering the latter against the film to ensure the fixing of the closure profiles.
  • document US-A-5111643 proposes a complex installation comprising a chute which opens out at the base of the forming neck to convey the closure profiles carried by a support strip, and a discharge chute for the support strip.
  • the present invention now aims to improve the machines for forming film-based packaging comprising complementary closure profiles.
  • the invention preferably applies to machines for forming, filling and automatically closing film-based packaging, of the type known per se comprising a forming neck which receives the film in the plane state coming 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 transversely on the film before it reaches the forming neck and to fix these 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 by the chute filling, then a second transverse seal when the product has been introduced into the tube, to close a package around the latter.
  • the present invention goes against the prejudice linked to the means of implementation described in the first documents US-A-4617683 and US-A-4655862. Indeed, while many designers considered that the means described in these documents could not be satisfactory, which led to the many subsequent proposals mentioned above, the present inventors, after many experiments have found that a solution inspired by the means described in these documents US-A-4617683 and US-A-4655862, could give satisfaction, subject to an improvement consisting in combining a straight guide and a gripping means operating by traction on the closing profiles.
  • the means for conveying the closure profiles are adapted to fix to the film one of two complementary profiles, in engagement, each having a length of the order of half the width of the film, and means are further provided capable of fixing the second closure profile, on the internal wall of the film shaped into a sachet, after filling thereof, when the sachet is finished.
  • the two closure profiles are carried by support strips of different width.
  • the rectilinear guide 100 can be the subject of different embodiments.
  • the guide 100 is formed of a rigid rectilinear channel of complementary section of at least part of the closure profiles P.
  • the rectilinear guide 100 consists of a channel formed by two pivoting jaws, receiving in the closed position, the profile P conveyed by the means 150, but capable of opening to then facilitate the removal of the profiles P on the underlying films F.
  • the gripping means 150 can also be the subject of different embodiments.
  • these gripping means are preferably formed by a clamp system controlled on closing to grip the upstream end of a profile P, in order to route it in the straight guide 100, then opening to release the profile P before returning to the initial gripping position shown diagrammatically in FIG. 1.
  • the gripping means 150 may be formed of a suction head.
  • means for transverse displacement of the gripping means 150 are provided, synchronized with the movement of the film F.
  • Auxiliary means are preferably provided for conveying the profiles P: drive rollers 200, 202, a guide 204 of the profiles upstream of the film F, means 206 for sectioning the profiles P, by section (the profiles P preferably being routed from a coil reel 208) and a position sensor 210.
  • closure profiles P are fixed to the film F by any suitable means, advantageously using welding jaws, associated with the straight guide 100, as shown diagrammatically under the reference 120 in FIG. 1.
  • the system is suitable for depositing closure profiles P covering the entire width of the film F, these profiles P being fixed on the film F over their entire length, as shown diagrammatically in FIG. 3 and engaging only after folding and crushing of the tubular film after filling the bag, during the finishing thereof.
  • the system can be adapted to deposit directly on the film F a pair of profiles P in engagement, covering only half the width of the film F, one P1 of the two profiles, adjacent to the film, being fixed on the latter at the deposition station, thanks to the welding jaws 120, while the second superimposed profile P2 is fixed on the internal wall of the bag, when the latter is finished ci, after filling.
  • the second section P2 can be welded to the film F by means of the welding jaws 50, or also by means of additional transverse welding jaws 52, as shown diagrammatically in FIG. 4.
  • the support strip 54 of the second profile P2 is wider than the support strip 56 of the first profile P1, to facilitate the second weld.
  • the profile P being arranged transversely on the film F before the latter reaches the forming neck 20, means are preferably provided facilitating the passage of this forming neck 20.
  • FIG. 4 there is shown diagrammatically at 51 a cutting tool associated with the transverse sealing jaws 50 for separating the sachets once finished, and diagrammatically at 53 a cutting tool capable of being used to make the pre-cut line 80.
  • closure profiles P themselves can be the subject of numerous variants.
  • FIG. 2 it can be complementary asymmetrical male / female profiles P1 and P2.
  • means are provided, for example in the form of bi-material profiles P or equivalent means, making it possible to define a melting temperature on the outer surface of the support strips 54, 56 lower than the melting temperature on their internal surfaces .
  • the film F used can also be the subject of numerous variants. It may be a flexible film of monolayer or multilayer plastic, if necessary coated, for example metallized.
  • the gripping means can be formed of a needle carried by drive means adapted to, on the one hand, move the needle alternately, by translation or pivoting, in approach and away from the guide 100, to prick the profile P in the close position of the guide and on the other hand to move the needle alternately back and forth along the guide 100.
  • these drive means are suitable for 1) bringing the needle closer to the upstream end of the guide 100 to prick the free end of the profile P coming from the reserve 208, 2) move the needle along the guide 100 while keeping the needle in the close position engaged with the profile to convey the latter by pulling on its upstream end, 3) move the needle away from the guide 100 to release the profile P at the end of the routing stroke, and 4) move the needle back along the guide 100 towards the e x upstream end of the latter while maintaining the needle in a free distant position relative to the profile, before repeating a drive cycle from step 1) for the next section of profile P.
