Definitions
- the present invention relates to the field of automatic formation, filling and closing of packaging bags resealable with flexible films, for example of material thermoplastic, fitted with added profiles, especially male and female complementary zipper.
- closure profiles very often prove to be very delicate and regularly requires interventions delaying the manufacturing process.
- this implementation requires major changes when you want transform conventional automatic machines for training, filling and closing of film-based packaging bags thermoplastic materials.
- EP-A-531701 describes a packaging machine comprising means adapted to fix two to a film separately support profiles, then fold the film thus fitted around products to wrap, fix the longitudinal edges of the film and weld it transversely to close the packaging around the products.
- the present invention therefore aims to perfect known machines for forming, filling and automatic closure of reclosable film-based packaging bags made of flexible material.
- the strip carrying the complementary profiles is folded into a U and said profiles complementary are engaged when fixing the strip on the film.
- the strip bearing the closing profiles can be in the flat state during welding on the flexible film.
- the present invention also relates to a method of automatic formation, filling and closing of packaging bags resealable as well as the sachets obtained by the implementation of this process.
- the invention essentially differs from the state of the technique illustrated in this figure by the fact that the closure profiles are not routed on the forming neck and fixed on the film at level of this forming neck, but fixed on the film upstream of this forming neck.
- FIGS. 2a to 2d We will first describe the first variant of implementation work in accordance with the present invention illustrated in FIGS. 2a to 2d.
- a flexible film 1 in the planar state from for example an unwinder and a strip 100 of flexible material which carries additional closing profiles 110, 112. More specifically, according to the variant of implementation of FIGS. 2, the strip 100 is folded back on itself in a U shape and the complementary profiles 110, 112 are engaged when the strip 100 is attached to the film 1 as illustrated in Figure 2a.
- the weld zone between the wing 102 and the film 1 is referenced 150. It will be noted that preferably this weld zone 150 is confined in a region located beyond the profiles 110, 112, that is to say between these profiles 110, 112 and the free ends 103, 105 of the wings 102, 104 of the strip 100.
- the cutout 160 is made on the side of the weld zone 150 opposite the opening of the strip 100 folded in U.
- the film 1 is present in the form of two sections: a first section la on which the strip 100 is fixed by the weld zone 150, and a second section 1b separate.
- the first the stretch of the film is folded 180 ° on itself so that the wing 102 of the strip 100 is found adjacent to the surface of the section opposite it the adjacent one.
- the second section 1b is close to the end 105 of the second wing 104 of the strip 100 and welded to this wing 104 at a weld zone referenced 152.
- the strip 100 folded in U forms in combination with the 180 ° bend, referenced 170, a Z.
- the film 1 plus strip 100 assembly illustrated in FIG. 2d can then be routed to a forming collar comparable to that illustrated in FIG. 1 to conform the film to the tubular state and form and close sachets from this tubular film by means of longitudinal and transverse welding such as the means illustrated below reference 30 and 40 in FIG. 1.
- the strip 100 is welded by its external surface to the sections 1a and 1b of the film 20.
- the film 1 is folded on itself in the form of a fold 170 to 180 ° adjacent to the end 103 of the wing 102 and around the strip 100 in U in the form of a second fold 172 also at 180 °.
- the second wing 104 of the strip 100 is welded near its free end 105 on the second section 1b now adjacent to film 1, at an area of solder 152.
- the assembly comprising the film 1 and the strip 100 thus obtained is then routed to the forming neck of a machine for filling and closing classic sachets.
- a thermal interlayer insulation is placed between the free ends of the wings 102, 104 during the welding 150, 152 to avoid direct welding of the ends 103, 105 of these wings between them; or we make sure to use a strip 100 having on its internal surface a melting point greater than that of its outer surface.
- FIG. 4a thus shows a flat strip 100 fitted with additional closing profiles 110, 112 attached to a flat film 1, and in FIG. 4b the same flat strip 100 welded to the film plane 1 in the vicinity of its ends, at the level of two zones 150, 152.
- the strip 100 could be welded over the entire width of its surface adjacent to the film 1 on the latter.
- the film assembly 1, strip 100 can be routed flat to the forming neck, the profiles 110, 112 being progressively brought together and engaged in the neck of forming using the means illustrated in FIGS. 1 to 6 of document FR-A-2583018.
- the film 1 / strip 100 assembly shown in FIG. 4b can be deformed in Z before transfer to the forming neck of a classic filling and closing training of sachets.
- the sections 110, 112 are carried in taken by folding the strip 100 in U on itself.
- the film 1 is folded into a Z thanks to a first fold 170 to 180 ° adjacent to one of the ends of the wings of strip 100 and a second fold 172 at 180 ° on the outside of strip 100 and half length of it.
- This fourth variant is related to the third illustrated in FIGS. 4a to 4c in the sense that the strip 100 is close together and welded in the planar state on the film 1 as illustrated on the Figures 5a and 5b.
- the ends 103, 105 of the strip 100 are fixed respectively on sections la and 1b separate from film 1.
- the assembly comprising the two sections 1a and 1b of film 1 connected by the flat strip 100 provided with closure profiles 110, 112 can be routed in the planar state to the forming neck of a automatic filling and closing of sachets training then progressive reconciliation of profiles 110, 112 and engagement thereof by means illustrated in FIGS. 3 to 6 of document FR-A-2508013 or even folded in Z as illustrated in FIG. 5c thanks to the realization of a fold 170 of one of the sections la or 1b of the film 1, at 180 ° on itself near the end 103, 105 of one of the wings 102, 104 of the strip 100.
- the whole film 1, tape 100 arranged in Z can be routed in a conventional manner to the forming neck a machine for forming, filling and automatically closing sachets.
- the film 1 used in the context of the invention may be conform to the arrangements known to those skilled in the art.
- these sections 110, 112 can be associated with one or more cords integrated into the band 100 to facilitate the opening of the packaging sachets.
- the invention is not limited to the formation of film-based sachets in thermoplastic materials.
- profiles 110, 112 capable of to equip a wrapping film, such as for example integrated cords to the film to make it easier to open, decorative borders by example of colored borders or graduated borders for marking the volume of the product contained in the packaging.
- the free ends of the strip 100 are arranged between the free ends of the sheets 1a, 1b.
- the areas of weld defined between the sheets la, 1b and the ends of the strip 100 are illustrated in 150, 152.
- FIG. 7 a variant has been illustrated according to which the film 1 is not composed of two separate sheets 1a, 1b but of a single film folded in U and whose free ends are fixed respectively on the ends of the strip 100.
- the ends of the film 1 are placed on the outside of the ends of the strip 100 (alternatively, they could be placed on the inside).
- FIG. 8 shows another variant according to which the film is folded into a U and the core of the U thus formed on the film 1 is placed between the two wings of the strip 100, itself U-shaped.
- the film 1 also defines two sheets 1a, 1b adjacent and parallel joined by the aforementioned U-shaped core.
- the film 1 is provided at the level of the core lc with a zone of weakness 1d, for example in the form of a pre-tear or dotted line, of central preference.
- connection zones 150, 152 can be obtained by welding or by collage.
- the sheets 1a, 1b illustrated in FIGS. 6, 7 and 8 can be open, i.e. separated, by any appropriate means, so that the film 1 reaches the entrance of the forming neck in a substantially flat state.
- the ends of the U-shaped strip 100 are bent 90 ° outwards so that the strip 100 has the general shape of a U.
- the core of the strip 100 is arranged in a groove complementary longitudinal 222 formed in the counter blade 220.
- the ends of the strip 100 define coplanar sections 100a, 100b, arranged between the adjacent faces opposite the blade 210 and the counter blade 220.
- the film 1 is also routed between the blade 210 and the counter blade. 220, thus the latter ensure the connection between the film 1 and the sections 100a, 100b of the strip 100, by pressure and thermal input.
- the roller 200 is arranged under the strip 100 folded in T.
- the roller 200 comprises by consequently an annular groove opening on its periphery for the passage of the web of the strip 100.
- the film 1 is routed between the blade 210 and the counter blade 220 in the form of two separate sections 1a, 1b.
- the roller 200 is placed above the strip 100.
- the film 1 can in this case be continuous, being, where appropriate, provided with a tearable dotted line or equivalent 1d as indicated previously.
