- 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, 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 filler neck, then a second transverse weld when the product has been introduced into the tube, to close a package around the latter.
- the present invention now aims to improve the machines thus known.
- a machine for forming, filling and automatically closing packaging bags comprising means capable of generating at least one fold on the film intended to constitute a bag, to form at least one bellows on the final bag.
- the aforementioned fold can be longitudinal, that is to say parallel to the direction of film travel, or transverse, that is to say perpendicular to this direction of travel of the film.
- the machine further comprises means capable of defining step by step areas for fixing a fold mentioned above in places preferably corresponding to the transverse welds, before formation of the sachets.
- two folds are provided, longitudinal or transverse, intended to form lateral bellows on the bag, transversely to the closure profiles.
- the fold, longitudinal or transverse is produced in the form of a Z-fold in the body of the film.
- the longitudinal or transverse fold is produced by adding a folded strip corresponding, for example, to the desired bottom gusset, on a film.
- the present invention also relates to a method for manufacturing packaging bags on a machine for forming, filling and automatically closing packaging bags, which method comprises the step of generating at least one fold on the film intended to constitute a sachet, to form at least one bellows on the final sachet.
- the method further comprises the step of defining step by step attachment zones of the above fold in places preferably corresponding to the transverse welds, before formation of the sachets.
- the step of generating the fold consists in producing a Z-fold in the body of the film.
- the step of generating the fold consists in making the fold by adding a strip folded longitudinally and corresponding for example to the desired bottom gusset, on a film.
- the bag comprises a bottom bellows.
- the invention is not limited to this provision.
- the invention can be applied to the production of bags comprising two lateral bellows.
- the fold produced on the film is a longitudinal fold, that is to say parallel to the direction of movement of the film. Then, other variants will be described according to which the fold is produced transversely on the film.
- a packaging bag 10 formed using a film 12. It is preferably a film thermoplastic. However, the invention can extend to any flexible film capable of constituting a packaging sachet.
- the bag 10 comprises a closure assembly 20 formed by two complementary closure profiles 22 and 24, respectively male and female, fixed on the internal surface of the bag 10, at the mouth 11 of the latter.
- the sections 22 and 24 extend, in longitudinal direction according to the first embodiments, on the film 12 during the process of manufacturing the bag. The latter is closed transversely (that is to say perpendicular to the sections 22, 24) by welds 30.
- the bag 10 is provided with a bellows 40 on its bottom opposite to the mouth 11.
- the bellows 40 is composed of two facets 42, 44 which form a dihedral internal to the bag, concave towards the outside.
- Profiles 22 and 24 can take many configurations. They can for example have come from molding with the film 12, or be attached to it. For this, the profiles 22 and 24 can be carried by respective bands 23, 25 as illustrated in particular in FIGS. 3 and 4 or carried by a single band 28 folded in a U as illustrated in particular in FIG. 1.
- These strips 23, 25, 28 can be fixed to the internal surface of the film 12 (or even external for the strip 28) by any suitable means, preferably by welding.
- the closure assembly 20 can be provided with a longitudinal cord 26 facilitating the opening of the bag.
- the bag 10 can be closed longitudinally by the strip 28 supporting the profiles 22 and 24 as illustrated in FIG. 1 or by a longitudinal weld 14 as illustrated for example in FIGS. 3 and 4.
- This longitudinal weld 14 can be formed in different places of the bag 10, for example over the width of the side walls 15, 16, in the body of the bag 10, as illustrated in FIGS. 3 and 4 or at the junction zone of a side wall 16 and the bottom bellows 40 as illustrated in FIGS. 5 and 6.
- the overlap of the two edges of the film 12, at the level of the longitudinal weld 14 may itself be an overlap on the right or on the left, as illustrated in FIGS. 3, 4 and 3a, 4a.
- the film 12 can be a single flexible single-layer film as illustrated in FIG. 1 or a complex film composed of different adjacent layers, for example coextruded, as illustrated in FIG. 2.
- the U-shaped band 28 supporting the profiles 22 and 24 is welded to half its width, on the edges 18, 19 of the film 12.
- a first external fabric 29 is thus formed, passing through the web of the U-shaped band 28, and a second inner fabric 30 passing through the sections 22 and 24.
- This effect can be reinforced, and even guaranteed, if, as illustrated in FIG. 7, the second inner fabric 30 which carries the profiles 22 and 24 is of longer dimensions than the outer fabric 29.
- FIGS. 7 and 8 Illustrated in FIGS. 7 and 8, a variant according to which the U-shaped band 28 is fixed to the inner surface of the edges 18, 19 of the film 12.

- the U-shaped band 28 is fixed to the edges 18, 19 of the film 12, at the level of zones of the band 28 comprised between the sections 22, 24 and the center of the band. 28, provided for example with the opening cord 26.
- this strip 28 it is possible to fix this strip 28 in a U shape, on the edges 18, 19 of the film 12, at the level of zones of the strip 28 located between the profiles 22, 24 and the longitudinal free edges of the U-shaped band 28.
- the strip 28 is fixed by its longitudinal edges on the outer surface of the edges 18, 19 of the film 12.
- the strip 28 could be fixed, by its longitudinal edges, on the internal surface of the edges 18, 19 of the film 12.
- the loop closure assembly thus formed can be welded in height, on an edge of the film 12, like a fold.
- the machine 100 includes means 118 capable of defining step by step fixing zones 13 of the aforementioned fold in places corresponding to the transverse welds (carried out subsequently), before formation of the sachets. .
- These fixing means 118 are preferably provided at the part 104 or the part of the machine 100 located immediately downstream.
- these means can be designed to fix the fold, by static discharge, partial gluing or any other equivalent fixing means.
- the above-mentioned fixing means 118 are preferably adjustable over the length of the film 12 to allow precise adjustment thereof with respect to the zones corresponding subsequently to the transverse welds.
- This fixing thus constitutes an essential characteristic of the present invention. It should also be noted that this attachment being located at the place of the transverse welds, said attachment 13 does not in any way disturb the production. subsequent of the sachet.
- this fixing 13 step by step of the fold P makes it possible to facilitate the production of the transverse welds taking into account the extra thickness at this level resulting from the fold intended to form the bellows.
- the film 12 provided with the fold P is then conveyed in a manner known per se to the FFS machine proper comprising a forming neck 120, a filling chute 130, longitudinal welding means 135 and transverse welding means 140.
- the fixing means 118 make it possible to fix two of the walls of the fold P in the case of a complex film 12 and three parts in the case of a simple film 12.
- the final fold P is preferably formed during the gripping of the film 12, on the one hand on the side of the profiles 22, 24, on the other hand on the side of the fold P, by a set of pneumatic, hydraulic, electromagnetic or mechanical 150 which pinch and stretch the film 12 at the time of the transverse welding.
- Such clamps 150 are therefore controlled sequentially upon opening and closing on the one hand to grip the film and in lateral displacement to ensure a certain tension of the film 12 and to avoid any stray folds on the other hand.
- FIG. 15 Such a clamp system is shown diagrammatically in FIG. 15.
- the fold P can be positioned on one side or the other of the axis of the tube 130, with respect to the longitudinal weld 14.
- the present invention makes it possible to produce, with the same filling tube 130 and the same training neck 120, the cost of which is high in an FFS machine, depths of fold P, and therefore of bellows 40, different simply in modifying the covering surface of the plates 112, 114 making up the conformation baffle 110.
- the P fold can be finalized by forcing in the conditioning tube 130.
- Such a window 132 and the corresponding training technique are notably illustrated in FIGS. 22 to 25.
- the bellows 40 is formed by Z-folding of the film 12.
- the bellows 40 can be produced by adding a strip 50 of film at the level of the formation neck 120.
- This strip 50 is fixed to the film 12 by any conventional technique , preferably by welding.
- This technique allows, on a complex or simple film 12 provided with a closure assembly 20 before the neck 120 passes, to add a strip 50 of complex or simple film which, by longitudinal welding, forms the bottom gusset 40.
- transverse weld 30 can be straight or curved to facilitate self-maintenance of the bag in the vertical position after deployment of the bellows 40. More specifically in this case the transverse welds 30 produced on the two sides of the bag are symmetrical. To produce such curved transverse welds 30, it suffices to conform the transverse welding jaws 140 accordingly.
- the strip 50 intended to form the bellows 40 can be folded beforehand or folded on the conditioner. It is also prefixed step by step at the areas 13 corresponding to the transverse welds 30, as indicated above.
- the dimension of the final bellows 40 depends on the width of the strip 50 used.
- the film 12 can be provided with the closure assembly 20 before the ply P is produced (the closure assembly 20 being originally linked to the film 12 or attached to it) or even be provided of this closure assembly immediately upstream of the training neck 120.
- the advance of the film 12 can be timed and synchronized with the operation of the welding jaws 135, 140, or continuous.
- the transverse welds 30 can be produced either to ensure a connection between the two walls 42 and 44 of the bottom bellows at the level of the transverse welds 30, or to avoid such a connection.
- the bag 10 comprises two longitudinal bellows 40a, 40b, parallel to the closure profiles 20. More specifically, according to Figure 26 the two bellows 40a, 40b, are equidistant of the closure assembly 20. However, this equi-distance is not absolutely required.
- FIG. 27 also shows an alternative embodiment of bags comprising two lateral bellows 40a, 40b, extending perpendicular to the closure assembly 20.
- These lateral bellows 40a, 40b are also obtained using folds longitudinal produced on the film before the latter reaches the forming neck, or by adding suitable strips 50 to the film, as described above.
- means are provided for depositing the closure assembly 20 on the film 12 transversely to the direction. movement of the film.
- Such means of conveying the closure assembly 20 in a transverse direction may conform, for example, to the means described in documents US-A-4617683, US-A-4655862, US-A-4666536, US-A- 4701361, US-A-4709398, US-A-4878987, US-A-4844759, US-A-4929225, US-A-4909017 and US-A-5111643.
- the closure assembly 20 is adjacent to one of the transverse welds 32, in order to guarantee the tightness of the bags despite the presence of the lateral bellows 40a, 40b.
- the fold 40 intended to form the bellows can be a transverse fold, that is to say perpendicular to the direction of movement of the film 12.
- the fold 40 in the form of a transverse z-fold in the body of the film 12.
- the transverse fold 40 is produced using a strip 50 folded longitudinally in a U on itself, attached to the film 12.
- FIG. 28 there is shown diagrammatically in FIG. 28 such a U-shaped strip 50, convexity directed towards the rear with respect to the direction of movement of the film 12, connected (coming from material) initially to the support strips 23, 25 of the profiles 22, 24.
- the strip 50 connected to the profiles 22, 24, deposited on the film 12, has a length equal to half the width of the film 12.
- One side of the U-shaped strip and the adjacent support strip 23 are welded to the film 12 at the level of the deposition station, upstream of the forming neck 120.
- the other side of the U-shaped strip and the second support strip 25 are welded to the internal wall of the film 12 constituting the packaging after folding of this film in tubular configuration and filling of the packaging, that is to say during the finishing of this packaging, at the transverse welding station 140.
- Such a strip 50 linked to the sections 22, 24 can be conveyed transversely on the film 12 by means known for this purpose as described in the aforementioned documents.
- the transverse welding station 140 means capable of cutting this strip in order to separate the strip 50 in the actual U, intended to form a bellows, and the profiles 22, 24, along the cutting line. referenced 200 in Figure 28.
- the profiles 22, 24 are linked to the mouth area of a sachet which has just been individualized, while the strip 50 in U forms a bellows of background for the sachet being formed.
- such a U-shaped transverse strip 50 deposited on the film 12 can be separated from the origin of the transverse closing profiles 22, 24. This avoids the operation of subsequently cutting this strip as described for FIG. 28. However, it remains necessary to cut the bags in a manner known per se, along the line 202, between the closure profiles 22, 24 and the strip 50.
- the transverse welding operation of this strip 50 on the film 12 can be adapted either to fix the ends of the fold together, at the internal surfaces of the fold, in a manner comparable to FIG. 27, that is to leave the internal surfaces of the fold free, in a manner comparable to FIG. 26.
