Definitions
- the present invention relates to the field of packaging bags.
- the known means are generally satisfactory.
- the bags are most often formed from two flat sheets welded together on three sides and provided with closing means, for example complementary male / female profiles at the mouth of the bags.
- FIG. 1 appended Illustrated in FIG. 1 appended, in a schematic manner, a known technique for producing bags with lateral bellows by introduction of bellows 10 precut between two sheets 12 and 14 constituting the two main faces of the bags, at 90 ° from the direction of travel S of these leaves.
- Said sheets 12, 14 are provided with longitudinal male / female closure profiles 13, 15.
- the bellows 10 Preferably have a variable width, increasing in distance from the closure profiles 13, 15 to allow the bags to be inflated.
- This known technique certainly makes it possible to produce packaging bags with side gussets. However, it turns out to be quite complex.
- the need to introduce the bellows 10 at 90 ° from the direction of travel of the sheets 12, 14 does not allow high production rates and requires perfect synchronism between the travel of the sheets 12, 14 and the introduction of the bellows 10 .
- Document FR-A-2 686 063 describes another technique for manufacturing bellows packaging bags which consists in preforming a bag with side gussets, split the bag over part of its length along the outer fold lines of the bellows, fold down on the outside of the bag, flaps thus delimited, deposit closure profiles on these flaps, reform the bag and weld the closure profiles on said flaps in place.
- this technique is not entirely satisfactory given its complexity.
- the present invention now aims to improve the means of manufacturing known side bellows packaging bags.
- the present invention also relates to a device for implementing this method, as well as the sachets obtained.
- FIG. 2 shows a film 100 provided with two Z-folds, 110, 120, parallel to the longitudinal direction D of the film 100.
- the two Z folds 110 and 120 can be formed by any suitable means.

- the folds 110 and 120 are intended to form the side bellows of the bag once it is finished.
- the film illustrated in FIG. 2 has a flat main face 130, intended to form a main face of the bag after its completion.
- This main face 130 is extended on either side, on its longitudinal edges, by first longitudinal flaps 112 and 122 themselves extended by second longitudinal flaps 114 and 124.
- the flaps 112 and 114 form the fold 110.
- the flaps 122 and 124 form the fold 120.
- the flaps 112 and 122 are connected to the main face 130 by fold lines 111 and 121.
- the flaps 112 and 122 are folded towards the middle of the face 130 from the fold lines 111 and 121 so that they are underlying the main face 130.
- the flaps 114 and 124 are connected to the flaps 112 and 122 by fold lines 113 and 123.
- the flaps 114 and 124 extend towards the exterior from the fold lines 113 and 123.
- the flaps 114 and 124 also have widths identical to the flaps 112 and 122 so that they are respectively underlying and superimposed thereon.

- the two sections 140 and 142 Preferably as shown in FIG. 2, the two sections 140 and 142 have identical widths. However, this condition is not imperative.
- the main thing is that the sections 140 and 142 have a cumulative width slightly greater than the face 130 to form the second face of the bag after having been connected by their free external longitudinal edge, as will be seen below with reference to the figure. 8.
- the flaps 114 and 124 are substantially coplanar with the sections 140 and 142.
- the flaps 114 and 124 are connected to the sections 140 and 142 by lines 115 and 125.
- the bag-forming method comprises a step of cutting at regular intervals two notches 150, 160 in each of the zones intended to form the side bellows.
- notches 150 and 160 appear in their real configuration within the folds 110 and 120 in FIG. 6.
- the notches 150 and 160 can be formed in the film 100 before the folds 110 and 120 are produced. In this case, they initially have the geometry illustrated in FIG. 5.
- the notches 150 and 160 are formed after completion of the folds 110 and 120.
- the notches 150 and 160 can be made in the film 100 by any suitable means.
- the notches 150 and 160 are produced using the blade 200 as an anvil for the cutting punch, in order to preserve the face 130 of the film.
- the configuration of the notches 150 and 160 can be the subject of various variants.
- the notches 150 and 160 extend between the lines 111 and 115 on the one hand and 121 and 125 on the other hand as illustrated in FIG. 5.
- the notches 150 and 160 can be formed back from lines 111 and 115, 121 and 125 above, as illustrated in FIG. 5a.
- each notch 150 and 160 is delimited by two longitudinal edges 152, 154 and 162, 164 and two transverse edges 156, 158 and 166, 168.
- the longitudinal edges 152, 154 and 162, 164 are rectilinear and coincide respectively with the lines 111, 115, 121 and 125 according to FIG. 5, which themselves correspond to the final external generators of the side bellows. In the folded state illustrated in FIG. 6, the two edges 152 and 154, respectively 162 and 164 are superimposed.
- the transverse edge 156, 166 closest to the mouth of the sachets is preferably straight and transverse to the longitudinal direction D of the film 100.
- the second transverse edge 158, 168 closest to the bottom of the sachets is preferably non-rectilinear, concave towards the mouth of the sachets. More precisely still, this second transverse edge 158, 168 is preferably formed of a dihedral composed of two rectilinear sections 158a and 158b, 168a and 168b.
- the two aforementioned sections 158a and 158b, 168a and 168b respectively constituting one of the second transverse edges 158 and 168 are preferably of identical length. They extend respectively over one of the flaps 112 and 114, 122 and 124. Thus the sections 158a and 158b, 168a and 168b intersect on the median fold line 113, 123.
- the inclination of the sections 158a and 158b, 168a and 168b relative to a line transverse to the longitudinal direction D is of the order of 15 °, so that the angle of the dihedron formed by the sections 158a and 158b, 168a and 168b is of the order of 150 °.
- the generally planar film 100 provided with two Z-folds 110, 120 and equipped with two notches 150, 160 as shown in FIGS. 5 and 5bis is preferably directed to a conventional "filling, filling and closing" machine for producing the bags.
- 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 and supplies the film shaped as a tube at the outlet, a filling chute which opens into this forming neck and consequently into 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 bag around it.
- complementary male / female closure profiles 170 are deposited on the film 100 at the mouth of a bag, transversely to the longitudinal direction D, before the film 100 is not routed on the forming neck of the FFS machine as illustrated in FIG. 7.
- closure profiles 170 are placed against the main face 130, opposite the notches 150 and 160, that is to say between the transverse edges 156 and 158, respectively 166 and 168.
- the length of the closure sections 170 is preferably equal to the width of the main face 130, ie the distance separating the fold lines 111 and 121.
- the sections 170 are immobilized in position on the film 100 by any suitable means.
- the sections 170 are only initially fixed by their ends on the film 100 by means of spot welding.
- the fixing of the profiles 170 over their entire length on the internal face of the faces principal of the bag is ensured subsequently, preferably during the production of the transverse welds which will be described below with reference to FIG. 9.
- the fixing of the sections 170 by spot welding at their ends can moreover be accompany a spot weld of the lateral edges of the bag, opposite the folds 110, 120, at the level of the future transverse weld zones illustrated in FIG. 9, to fix the aforementioned folds and avoid their deformation in the rest of the film routing 100.
- the aforementioned spot welding means are preferably adjustable over the length of the film 100 in order to allow them to be precisely adjusted with respect to the zones corresponding subsequently to the transverse welds and to the length of the sachets sought.
- the instants for controlling these spot welding means should also be carefully synchronized with the travel of the film 100, since the instants for controlling these spot welding means control both the location of the corresponding welding zones. and the step of these zones.
- the fixing of the closure sections 170 by their ends and, where appropriate, the point fixing of the folds 110 and 120 makes it possible to facilitate the subsequent routing of the film 100 and also makes it possible to facilitate the subsequent production of the welds illustrated in FIG. thanks to the crushing resulting from the ends of the sections 170.
- the aforementioned spot welding means may generally conform to the means described in document FR-A-2 638 419.
- the fixing of the closure profiles 170 and the temporary fixing by points of the folds 110 and 120 can be carried out not by thermal welding, but by any equivalent means, such as for example by static discharge or partial bonding.
- the means designed to deposit the closure sections 170 on the film 100 transversely to the longitudinal direction D of the film 100 can be the subject of numerous embodiments.
- these means may conform 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-4 909017 and US-A-5111643.
- the entire film 100 illustrated in FIG. 7 is directed towards the forming neck of an FFS machine, as indicated above.
- the film 100 is conformed to the tubular state as illustrated in FIG. 8.
- the external free edges 141 and 143 of the sections 140 and 142 are then joined and welded in a conventional manner per se, thanks to the aforementioned longitudinal welding means of the FFS machine.
- the tubular film is then filled with its content thanks to the filling chute provided for this purpose.
- tubular film is routed opposite the welding means provided to ensure the welds illustrated in FIG. 9.
- transverse weld 180 coincides with the transverse edge 156, 166 of the notches.
- This transverse weld 180 is intended to form the bottom of a sachet. It ensures the connection of four film thicknesses at the side bellows (the two sides main and side gussets) and two thicknesses of film between these gussets (corresponding to the main faces).
- transverse weld 182 is produced between the transverse edges 156 and 158, respectively 166 and 168 of the notches. This transverse weld 182 is intended to form the mouth of a sachet. It connects the two main faces together.
- a transverse rectilinear cutting line 181 can be made between them to separate two adjacent sachets.
- the welds 184 and 186 are each formed of two sections 184a and 184b, 186a and 186b, which respectively cover the longitudinal edges 152, 154 and 162, 164 on the one hand and the transverse edges 158 and 168 on the other hand of the notches.
- the welds 184, 182 and 186 which intersect ensure a perfect seal on the mouth of the bags. More precisely, the sections 184a and 186a provide the connection of the outer edges of the two main faces of the bag while the sections 184b and 186b provide the connection between the edges 158a, 158b on the one hand and 168a, 168b on the other hand.
- the method according to the present invention has the fundamental advantage of limiting the welds 184, 182 and 186 to two film thicknesses, in particular at the place of fixing the closure profiles 170, whereas most of the conventional methods must carry out the welds on four film thicknesses at the side bellows.
- the film 100 can be the subject of numerous variants. It is preferably a thermoplastic film. However, the invention can extend to any flexible film capable of constituting a packaging sachet.
- the welds 184a, 186a can moreover be produced at least partially behind the fold lines 111, 115, 121, 125 as illustrated in the figure. 9.
- the variant embodiment of the notches illustrated in FIG. 5a makes it possible to improve the lateral tightness of the bags.

Abstract
Description
La présente invention concerne le domaine des sachets d'emballage.The present invention relates to the field of packaging bags.
De nombreux sachets d'emballage et de nombreux systèmes pour la fabrication de ceux-ci ont déjà été proposés.Many packaging bags and many systems for the manufacture of these have already been proposed.
Pour des sachets peu épais, généralement plats, à l'état rempli, les moyens connus donnent globalement satisfaction. Dans ce cas les sachets sont formés le plus souvent de deux feuilles planes soudées entre elles sur trois côtés et munies de moyens de fermeture, par exemple de profilés mâle/femelle complémentaires au niveau de l'embouchure des sachets.For thin bags, generally flat, in the filled state, the known means are generally satisfactory. In this case, the bags are most often formed from two flat sheets welded together on three sides and provided with closing means, for example complementary male / female profiles at the mouth of the bags.
En revanche jusqu'ici la réalisation de sachets destinés à recevoir un contenu épais, quelle que soit sa nature, ne s'avère pas totalement satisfaisante, bien que de nombreuses recherches aient été conduites dans ce domaine très particulier.However, so far the production of sachets intended to receive thick content, whatever its nature, has not been entirely satisfactory, although much research has been carried out in this very particular field.
En particulier de tels sachets requièrent souvent des soufflets latéraux délicats à réaliser.In particular, such bags often require delicate side gussets to produce.
On a illustré sur la figure 1 annexée, de manière schématique, une technique connue de réalisation de sachets à soufflets latéraux par introduction de soufflets 10 prédécoupés entre deux feuilles 12 et 14 constituant les deux faces principales des sachets, à 90° du sens de défilement S de ces feuilles. Lesdites feuilles 12, 14 sont munies de profilés de fermeture mâle/femelle longitudinaux 13, 15. De préférence les soufflets 10 présentent une largeur variable, croissante en éloignement des profilés de fermeture 13, 15 pour permettre le gonflage des sachets. Cette technique connue permet certes de réaliser des sachets d'emballage à soufflets latéraux. Cependant elle s'avère assez complexe. En particulier la nécessité d'introduire les soufflets 10 à 90° du sens de défilement des feuilles 12, 14 ne permet pas des cadences de fabrication élevées et requiert un synchronisme parfait entre le défilement des feuilles 12, 14 et l'introduction des soufflets 10.Illustrated in FIG. 1 appended, in a schematic manner, a known technique for producing bags with lateral bellows by introduction of bellows 10 precut between two sheets 12 and 14 constituting the two main faces of the bags, at 90 ° from the direction of travel S of these leaves. Said sheets 12, 14 are provided with longitudinal male / female closure profiles 13, 15. Preferably the bellows 10 have a variable width, increasing in distance from the closure profiles 13, 15 to allow the bags to be inflated. This known technique certainly makes it possible to produce packaging bags with side gussets. However, it turns out to be quite complex. In particular, the need to introduce the bellows 10 at 90 ° from the direction of travel of the sheets 12, 14 does not allow high production rates and requires perfect synchronism between the travel of the sheets 12, 14 and the introduction of the bellows 10 .
Le document FR-A-2 686 063 décrit une autre technique de fabrication de sachets d'emballage à soufflets qui consiste à préformer un sachet à soufflets latéraux, fendre le sachet sur une partie de sa longueur selon des lignes de pliage extérieures des soufflels, rabattre sur l'extérieur du sachet, des volets ainsi délimités, déposer des profilés de fermeture sur ces volets, reformer le sachet et souder les profilés de fermeture sur lesdits volets mis en place. Cette technique ne donne cependant pas totalement satisfaction compte tenu de sa complexité.Document FR-A-2 686 063 describes another technique for manufacturing bellows packaging bags which consists in preforming a bag with side gussets, split the bag over part of its length along the outer fold lines of the bellows, fold down on the outside of the bag, flaps thus delimited, deposit closure profiles on these flaps, reform the bag and weld the closure profiles on said flaps in place. However, this technique is not entirely satisfactory given its complexity.
La Demanderesse a également décrit plusieurs solutions alternatives de fabrication de sachets d'emballage à soufflets latéraux dans le document FR-A-2 745 263.The Applicant has also described several alternative solutions for manufacturing packaging bags with side gussets in document FR-A-2 745 263.
La présente invention a maintenant pour but de perfectionner les moyens de fabrication de sachets d'emballage à soufflets latéraux connus.The present invention now aims to improve the means of manufacturing known side bellows packaging bags.
Ce but est atteint dans le cadre de la présente invention grâce à un procédé de fabrication de sachets d'emballage tel que défini en revendication 1 annexée, laquelle tient compte du document EP 0 934 209 opposable au titre de l'article 54 (3) CBE.This object is achieved in the context of the present invention by a method of manufacturing packaging bags as defined in claim 1 attached, which takes account of the document EP 0 934 209 enforceable under article 54 (3) EPC.
La présente invention concerne également un dispositif pour la mise en oeuvre de ce procédé, ainsi que les sachets obtenus.The present invention also relates to a device for implementing this method, as well as the sachets obtained.
D'autres caractéristiques, buts et avantages de l'invention apparaîtront à la lecture de la descriptiorr détaillée qui va suivre, et en regard des dessins annexés donnés à titre d'exemple non limitatif et sur lesquels :
- la figure, 1 précédemment décrite représente schématiquement une technique classique de fabrication de sachets d'emballage à soufflets latéraux,

- la figure 5bis représente une vue similaire à plat d'une variante de film conforme à la présente invention muni d'encoches,
- et les figures 6 à 9 représente quatre étapes successives du procédé de formation de sachets conforme à la présente invention.
- the FIG. 1 previously described schematically represents a conventional technique for manufacturing packaging bags with side gussets,
- FIG. 2 represents a first step of a method in accordance with the present invention consisting in producing two Z-folds on a film.
- FIG. 3 represents a cross-sectional view of the same film,
- FIG. 4 represents a view similar to FIG. 2 and illustrates the portion of film removed to form notches,
- FIG. 5 represents a flat view of the same film provided with notches,
- FIG. 5a represents a similar flat view of a variant of film according to the present invention provided with notches,
- and FIGS. 6 to 9 represent four successive stages of the method for forming sachets according to the present invention.
On aperçoit sur la figure 2 un film 100 muni de deux plis en Z, 110, 120, parallèles à la direction longitudinale D du film 100.FIG. 2 shows a film 100 provided with two Z-folds, 110, 120, parallel to the longitudinal direction D of the film 100.
Les deux plis en Z 110 et 120 peuvent être formés par tous moyens appropriés.The two Z folds 110 and 120 can be formed by any suitable means.
De préférence ils sont formés chacun grâce à deux lames 200 et 202, respectivement 200 et 204, partiellement superposées en chevauchement comme illustré sur la figure 3 pour former une chicane dans laquelle est engagée le film 100.Preferably they are each formed by two blades 200 and 202, respectively 200 and 204, partially superimposed in overlap as illustrated in FIG. 3 to form a baffle in which the film 100 is engaged.
Les plis 110 et 120 sont destinés à former les soufflets latéraux du sachet une fois celui-ci terminé.The folds 110 and 120 are intended to form the side bellows of the bag once it is finished.
Ainsi après réalisation des plis 110 et 120, le film illustré sur la figure 2 présente une face principale plane 130, destinée à former une face principale du sachet après achèvement de celui-ci. Cette face principale 130 est prolongée de part et d'autre, sur ses bords longitudinaux, par des premiers volets longitudinaux 112 et 122 eux-mêmes prolongés par des seconds volets longitudinaux 114 et 124. Les volets 112 et 114 forment le pli 110. Les volets 122 et 124 forment le pli 120. Les volets 112 et 122 sont reliés à la face principale 130 par des lignes de pliage 111 et 121. Les volets 112 et 122 sont repliés vers le milieu de la face 130 à partir des lignes de pliage 111 et 121 de sorte qu'il sont sous-jacents à la face principale 130. Les volets 114 et 124 sont reliés aux volets 112 et 122 par des lignes de pliage 113 et 123. Les volets 114 et 124 s'étendent vers l'extérieur à partir des lignes de pliage 113 et 123. Les volets 114 et 124 ont par ailleurs des largeurs identiques aux volets 112 et 122 de sorte qu'ils sont respectivement sous-jacents et superposés à ceux-ci. Enfin chacun des volets 114 et 124 est prolongé vers l'extérieur par des tronçons auxiliaires 140 et 142. Ces tronçons auxiliaires 140 et 142 sont destinés à former en combinaison la seconde face principale des sachets. De préférence comme représenté sur la figure 2, les deux tronçons 140 et 142 ont des largeurs identiques. Cependant cette condition n'est pas impérative. L'essentiel est que les tronçons 140 et 142 possèdent une largeur cumulée légèrement supérieure à la face 130 pour former la seconde face du sachet après avoir été reliés par leur bord libre longitudinal externe, comme on le verra par la suite en regard de la figure 8.Thus, after completion of the folds 110 and 120, the film illustrated in FIG. 2 has a flat main face 130, intended to form a main face of the bag after its completion. This main face 130 is extended on either side, on its longitudinal edges, by first longitudinal flaps 112 and 122 themselves extended by second longitudinal flaps 114 and 124. The flaps 112 and 114 form the fold 110. The flaps 122 and 124 form the fold 120. The flaps 112 and 122 are connected to the main face 130 by fold lines 111 and 121. The flaps 112 and 122 are folded towards the middle of the face 130 from the fold lines 111 and 121 so that they are underlying the main face 130. The flaps 114 and 124 are connected to the flaps 112 and 122 by fold lines 113 and 123. The flaps 114 and 124 extend towards the exterior from the fold lines 113 and 123. The flaps 114 and 124 also have widths identical to the flaps 112 and 122 so that they are respectively underlying and superimposed thereon. Finally, each of the flaps 114 and 124 is extended outwards by sections auxiliaries 140 and 142. These auxiliary sections 140 and 142 are intended to form in combination the second main face of the sachets. Preferably as shown in FIG. 2, the two sections 140 and 142 have identical widths. However, this condition is not imperative. The main thing is that the sections 140 and 142 have a cumulative width slightly greater than the face 130 to form the second face of the bag after having been connected by their free external longitudinal edge, as will be seen below with reference to the figure. 8.
A l'issue de l'étape de formation des plis 110 et 120 illustrée sur la figure 2, les volets 114 et 124 sont sensiblement coplanaires des tronçons 140 et 142. Les volets 114 et 124 sont reliés aux tronçons 140 et 142 par des lignes 115 et 125.At the end of the step of forming the folds 110 and 120 illustrated in FIG. 2, the flaps 114 and 124 are substantially coplanar with the sections 140 and 142. The flaps 114 and 124 are connected to the sections 140 and 142 by lines 115 and 125.
Comme on l'a indiqué précédemment selon une caractéristique essentielle de la présente invention, le procédé de formation de sachet comprend une étape de découpe à intervalles réguliers de deux encoches 150, 160 dans chacune des zones destinées à former les soufflets latéraux.As indicated above according to an essential characteristic of the present invention, the bag-forming method comprises a step of cutting at regular intervals two notches 150, 160 in each of the zones intended to form the side bellows.
Les surfaces de matière retirée pour former ces encoches 150 et 160 sont représentées hachurées sur la figure 4.The surfaces of material removed to form these notches 150 and 160 are shown hatched in FIG. 4.
Ces encoches 150 et 160 apparaissent à l'état déployé sur la figure 5.These notches 150 and 160 appear in the deployed state in FIG. 5.
Enfin les encoches 150 et 160 apparaissent dans leur configuration réelle au sein des plis 110 et 120 sur la figure 6.Finally, the notches 150 and 160 appear in their real configuration within the folds 110 and 120 in FIG. 6.
Les encoches 150 et 160 peuvent être formées dans le film 100 avant réalisation des plis 110 et 120. Dans ce cas elles ont initialement la géométrie illustrée sur la figure 5.The notches 150 and 160 can be formed in the film 100 before the folds 110 and 120 are produced. In this case, they initially have the geometry illustrated in FIG. 5.
Cependant de préférence les encoches 150 et 160 sont formées après réalisation des plis 110 et 120. Les encoches 150 et 160 peuvent être réalisées dans le film 100 grâce à tous moyens appropriés. De préférence les encoches 150 et 160 sont réalisées en utilisant la lame 200 comme enclume pour le poinçon de découpe, afin de préserver la face 130 du film.However preferably the notches 150 and 160 are formed after completion of the folds 110 and 120. The notches 150 and 160 can be made in the film 100 by any suitable means. Preferably the notches 150 and 160 are produced using the blade 200 as an anvil for the cutting punch, in order to preserve the face 130 of the film.
La configuration des encoches 150 et 160 peut faire l'objet de diverses variantes.The configuration of the notches 150 and 160 can be the subject of various variants.
De préférence les encoches 150 et 160 s'étendent entre les lignes 111 et 115 d'une part et 121 et 125 d'autre part comme illustré sur la figure 5. Cependant, en variante, comme illustré sur la figure 5bis, les encoches 150 et 160 peuvent être formées en retrait des lignes 111 et 115, 121 et 125 précitées, comme illustré sur la figure 5bis.Preferably the notches 150 and 160 extend between the lines 111 and 115 on the one hand and 121 and 125 on the other hand as illustrated in FIG. 5. However, as a variant, as illustrated in FIG. 5a, the notches 150 and 160 can be formed back from lines 111 and 115, 121 and 125 above, as illustrated in FIG. 5a.
Plus précisément encore comme illustré sur les figures annexées de préférence chaque encoche 150 et 160 est délimitée par deux bords longitudinaux 152, 154 et 162, 164 et deux bords transversaux 156, 158 et 166, 168.More precisely still as illustrated in the appended figures preferably each notch 150 and 160 is delimited by two longitudinal edges 152, 154 and 162, 164 and two transverse edges 156, 158 and 166, 168.
Les bords longitudinaux 152, 154 et 162, 164 sont rectilignes et coïncident respectivement avec les lignes 111, 115, 121 et 125 selon la figure 5, qui correspondent elles mêmes aux génératrices extérieures finales des soufflets latéraux. Dans l'état plié illustré sur la figure 6, les deux bords 152 et 154, respectivement 162 et 164 sont superposés.The longitudinal edges 152, 154 and 162, 164 are rectilinear and coincide respectively with the lines 111, 115, 121 and 125 according to FIG. 5, which themselves correspond to the final external generators of the side bellows. In the folded state illustrated in FIG. 6, the two edges 152 and 154, respectively 162 and 164 are superimposed.
Le bord transversal 156, 166 le plus proche de l'embouchure des sachets est de préférence rectiligne et transversal à la direction longitudinale D du film 100.The transverse edge 156, 166 closest to the mouth of the sachets is preferably straight and transverse to the longitudinal direction D of the film 100.
Le second bord transversal 158, 168 le plus proche du fond des sachets est de préférence non rectiligne, concave vers l'embouchure des sachets. Plus précisément encore, ce second bord transversal 158, 168 est de préférence formé d'un dièdre composé de deux tronçons rectilignes 158a et 158b, 168a et 168b. Les deux tronçons précités 158a et 158b, 168a et 168b composant respectivement l'un des seconds bords transversaux 158 et 168 sont de préférence de longueur identique. Ils s'étendent respectivement sur l'un des volets 112 et 114, 122 et 124. Ainsi les tronçons 158a et 158b, 168a et 168b s'intersectent sur la ligne de pliage médiane 113, 123.The second transverse edge 158, 168 closest to the bottom of the sachets is preferably non-rectilinear, concave towards the mouth of the sachets. More precisely still, this second transverse edge 158, 168 is preferably formed of a dihedral composed of two rectilinear sections 158a and 158b, 168a and 168b. The two aforementioned sections 158a and 158b, 168a and 168b respectively constituting one of the second transverse edges 158 and 168 are preferably of identical length. They extend respectively over one of the flaps 112 and 114, 122 and 124. Thus the sections 158a and 158b, 168a and 168b intersect on the median fold line 113, 123.
A titre d'exemple non limitatif l'inclinaison des troncons 158a et 158b, 168a et 168b par rapport à une ligne transversale à la direction longitudinale D est de l'ordre de 15°, de sorte que l'angle du dièdre formé par les tronçons 158a et 158b, 168a et 168b est de l'ordre de 150°.By way of nonlimiting example, the inclination of the sections 158a and 158b, 168a and 168b relative to a line transverse to the longitudinal direction D is of the order of 15 °, so that the angle of the dihedron formed by the sections 158a and 158b, 168a and 168b is of the order of 150 °.
Le film 100 généralement plan, muni des deux plis en Z 110, 120 et équipé des deux encoches 150, 160 tel que représenté sur les figures 5 et 5bis est de préférence dirigé vers une machine de "formation, remplissage et fermeture" classique pour la réalisation des sachets.The generally planar film 100, provided with two Z-folds 110, 120 and equipped with two notches 150, 160 as shown in FIGS. 5 and 5bis is preferably directed to a conventional "filling, filling and closing" machine for producing the bags.
De telles machines sont souvent dénommées FFS, correspondant aux initiales de l'expression anglaise "Form, Fill and Seal machine".Such machines are often called FFS, corresponding to the initials of the English expression "Form, Fill and Seal machine".
On a déjà proposé de nombreuses machines de ce type.Many machines of this type have already been proposed.
La plupart de ces machines comprennent un col de formage qui reçoit en entrée le film à l'état plan et fournit en sortie le film conformé en tube, une goulotte de remplissage qui débouche dans ce col de formage et par conséquent dans ledit tube, des moyens de soudure longitudinale pour fermer le tube longitudinalement et des moyens aptes à générer séquentiellement une première soudure transversale avant qu'un produit ne soit introduit dans le tube par la goulotte de remplissage, puis une seconde soudure transversale quant le produit a été introduit dans le tube, pour fermer un sachet autour de ce dernier.Most of these machines include a forming neck which receives the film in the planar state and supplies the film shaped as a tube at the outlet, a filling chute which opens into this forming neck and consequently into 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 bag around it.
La structure générale de ces machines étant bien connue de l'homme de l'art, on ne décrira pas cette structure dans le détail par la suite.The general structure of these machines being well known to those skilled in the art, this structure will not be described in detail below.
On notera que de préférence dans le cadre de la présente invention, des profilés de fermeture 170 complémentaires mâle/femelle sont déposés sur le film 100 au niveau de la zone d'embouchure d'un sachet, transversalement à la direction longitudinale D, avant que le film 100 ne soit acheminé sur le col de formage de la machine FFS comme on l'a illustré sur la figure 7.It will be noted that preferably in the context of the present invention, complementary male / female closure profiles 170 are deposited on the film 100 at the mouth of a bag, transversely to the longitudinal direction D, before the film 100 is not routed on the forming neck of the FFS machine as illustrated in FIG. 7.
Plus précisément encore les profilés de fermeture 170 sont placés contre la face principale 130, en regard des encoches 150 et 160, c'est à dire entre les bords transversaux 156 et 158, respectivement 166 et 168.More precisely still, the closure profiles 170 are placed against the main face 130, opposite the notches 150 and 160, that is to say between the transverse edges 156 and 158, respectively 166 and 168.
La longueur des profilés de fermeture 170 est de préférence égale à la largeur de la face principale 130, soit la distance séparant les lignes de pliage 111 et 121.The length of the closure sections 170 is preferably equal to the width of the main face 130, ie the distance separating the fold lines 111 and 121.
Après leur pose sur le film 100, les profilés 170 sont immobilisés en position sur le film 100 par tous moyens appropriés. De préférence après leur pose, les profilés 170 sont uniquement fixés dans un premier temps par leurs extrémités sur le film 100 grâce à une soudure par points. La fixation des profilés 170 sur toute leur longueur sur la face interne des faces principales du sachet est assurée ultérieurement, de préférence lors de la réalisation des soudures transversales qui seront décrites par la suite en regard de la figure 9. La fixation des profilés 170 par une soudure par points au niveau de leurs extrémités peut d'ailleurs s'accompagner d'une soudure par points des bords latéraux du sachet, en regard des plis 110, 120, au niveau des futures zones de soudures transversales illustrées sur la figure 9, pour fixer les plis précités et éviter leur déformation dans la suite de l'acheminement du film 100.After being placed on the film 100, the sections 170 are immobilized in position on the film 100 by any suitable means. Preferably after their installation, the sections 170 are only initially fixed by their ends on the film 100 by means of spot welding. The fixing of the profiles 170 over their entire length on the internal face of the faces principal of the bag is ensured subsequently, preferably during the production of the transverse welds which will be described below with reference to FIG. 9. The fixing of the sections 170 by spot welding at their ends can moreover be accompany a spot weld of the lateral edges of the bag, opposite the folds 110, 120, at the level of the future transverse weld zones illustrated in FIG. 9, to fix the aforementioned folds and avoid their deformation in the rest of the film routing 100.
Cependant en variante on peut envisager de souder au moins l'un des profilés 170 sur le film 100 sur toute sa longueur dès sa pose.However, as a variant, it is possible to envisage welding at least one of the sections 170 on the film 100 over its entire length as soon as it is laid.
Les moyens de soudure par points précités sont de préférence réglables sur la longueur du film 100 pour permettre de régler avec précision ceux-ci par rapport aux zones correspondant ultérieurement aux soudures transversales et à la longueur des sachets recherchées.The aforementioned spot welding means are preferably adjustable over the length of the film 100 in order to allow them to be precisely adjusted with respect to the zones corresponding subsequently to the transverse welds and to the length of the sachets sought.
Bien entendu il convient également de synchroniser avec soin les instants de commande de ces moyens de soudure par points avec le défilement du film 100, puisque les instants de commande de ces moyens de soudure par points contrôlent à la fois le lieu des zones de soudure correspondantes et le pas de ces zones.Of course, the instants for controlling these spot welding means should also be carefully synchronized with the travel of the film 100, since the instants for controlling these spot welding means control both the location of the corresponding welding zones. and the step of these zones.
La fixation des profilés de fermeture 170 par leurs extrémités et le cas échéant la fixation par points des plis 110 et 120 permet de faciliter l'acheminement ultérieur du film 100 et permet également de faciliter la réalisation ultérieure des soudures illustrées sur la figure 9, notamment grâce à l'écrasement résultant des extrémités des profilés 170.The fixing of the closure sections 170 by their ends and, where appropriate, the point fixing of the folds 110 and 120 makes it possible to facilitate the subsequent routing of the film 100 and also makes it possible to facilitate the subsequent production of the welds illustrated in FIG. thanks to the crushing resulting from the ends of the sections 170.
Les moyens de soudure par points précités peuvent être globalement conformes aux moyens décrits dans le document FR-A-2 638 419.The aforementioned spot welding means may generally conform to the means described in document FR-A-2 638 419.
En variante la fixation des profilés de fermeture 170 et la fixation provisoire par points des plis 110 et 120 peut être réalisée non pas par soudure thermique, mais par tous moyens équivalents, tels que par exemple par décharge statique ou collage partiel.As a variant, the fixing of the closure profiles 170 and the temporary fixing by points of the folds 110 and 120 can be carried out not by thermal welding, but by any equivalent means, such as for example by static discharge or partial bonding.
Les moyens conçus pour déposer les profilés de fermeture 170 sur le film 100 transversalement à la direction longitudinale D du film 100 peuvent faire l'objet de nombreux modes de réalisation.The means designed to deposit the closure sections 170 on the film 100 transversely to the longitudinal direction D of the film 100 can be the subject of numerous embodiments.
A titre d'exemples non limitatifs, ces moyens peuvent être conformes aux moyens décrits dans les 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-4 909017 et US-A-5111643.By way of nonlimiting examples, these means may conform 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-4 909017 and US-A-5111643.
Une fois les plis 110, 120 réalisés et les profilés de fermeture 170 placés et au moins provisoirement fixés, l'ensemble du film 100 illustré sur la figure 7 est dirigé vers le col de formage d'une machine FFS, comme indiqué précédemment.Once the folds 110, 120 have been made and the closure profiles 170 placed and at least provisionally fixed, the entire film 100 illustrated in FIG. 7 is directed towards the forming neck of an FFS machine, as indicated above.
Le cas échéant des moyens spécifiques peuvent être prévus au niveau de ce col de formage pour faciliter son franchissement notamment par les plis 110, 120. A cette fin on peut par exemple prévoir des fenêtre complémentaires sur le col de formage pour recevoir les plis 110 et 120.Where appropriate, specific means can be provided at this forming neck to facilitate its crossing, in particular by the folds 110, 120. To this end, it is possible, for example, to provide additional windows on the forming neck to receive the folds 110 and 120.
A la sortie du col de formage, le film 100 est conformé à l'état tubulaire comme illustré sur la figure 8. Les bords libres externes 141 et 143 des tronçons 140 et 142 sont alors accolés et soudés de façon classique en soi, grâce aux moyens de soudure longitudinale précités de la machine FFS.At the exit from the forming neck, the film 100 is conformed to the tubular state as illustrated in FIG. 8. The external free edges 141 and 143 of the sections 140 and 142 are then joined and welded in a conventional manner per se, thanks to the aforementioned longitudinal welding means of the FFS machine.
Le film tubulaire est alors rempli de son contenu grâce à la goulotte de remplissage prévue à cet effet.The tubular film is then filled with its content thanks to the filling chute provided for this purpose.
Puis le film tubulaire est acheminé en regard des moyens de soudure prévus pour assurer les soudures illustrées sur la figure 9.Then the tubular film is routed opposite the welding means provided to ensure the welds illustrated in FIG. 9.
Il est ainsi réalisé au niveau de ces moyens de soudure de préférence :
- deux soudures transversales parallèles entre elles 180, 182 d'une part et
- une soudure 184, 186 sur la périphérie des encoches 150, 160.
- two transverse welds parallel to each other 180, 182 on the one hand and
- a weld 184, 186 on the periphery of the notches 150, 160.
L'une des soudures transversales 180 coïncide avec le bord transversal 156, 166 des encoches. Cette soudure transversale 180 est destinée à former le fond d'un sachet. Elle assure la liaison de quatre épaisseurs de film au niveau des soufflets latéraux (les deux faces principales et les soufflets latéraux) et deux épaisseurs de film entre ces soufflets (correspondant aux faces principales).One of the transverse welds 180 coincides with the transverse edge 156, 166 of the notches. This transverse weld 180 is intended to form the bottom of a sachet. It ensures the connection of four film thicknesses at the side bellows (the two sides main and side gussets) and two thicknesses of film between these gussets (corresponding to the main faces).
L'autre soudure transversale 182 est réalisée entre les bords transversaux 156 et 158, respectivement 166 et 168 des encoches. Cette soudure transversale 182 est destinée à former l'embouchure d'un sachet. Elle relie entre elles les deux faces principales.The other transverse weld 182 is produced between the transverse edges 156 and 158, respectively 166 and 168 of the notches. This transverse weld 182 is intended to form the mouth of a sachet. It connects the two main faces together.
Une fois les soudures 180 et 182 réalisées, une ligne de découpe rectiligne transversale 181 peut étre réalisée entre celles-ci pour séparer deux sachets adjacents.Once the welds 180 and 182 have been made, a transverse rectilinear cutting line 181 can be made between them to separate two adjacent sachets.
Les soudures 184 et 186 sont formées chacune de deux tronçons 184a et 184b, 186a et 186b, qui couvrent respectivement les bords longitudinaux 152, 154 et 162, 164 d'une part et les bords transversaux 158 et 168 d'autre part des encoches.The welds 184 and 186 are each formed of two sections 184a and 184b, 186a and 186b, which respectively cover the longitudinal edges 152, 154 and 162, 164 on the one hand and the transverse edges 158 and 168 on the other hand of the notches.
Ainsi les soudures 184, 182 et 186 qui s'intersectent permettent d'assurer une étanchéité parfaite sur l'embouchure des sachets. Plus précisément les tronçons 184a et 186a assurent la liaison des bords extérieurs des deux faces principales du sachet tandis que les tronçons 184b et 186b assurent la liaison entre les bords 158a, 158b d'une part et 168a, 168b d'autre part.Thus the welds 184, 182 and 186 which intersect ensure a perfect seal on the mouth of the bags. More precisely, the sections 184a and 186a provide the connection of the outer edges of the two main faces of the bag while the sections 184b and 186b provide the connection between the edges 158a, 158b on the one hand and 168a, 168b on the other hand.
Le procédé conforme à la présente invention présente l'avantage fondamental de limiter les soudures 184, 182 et 186 à deux épaisseurs de film, notamment à l'endroit de fixation des profilés de fermeture 170, alors que la plupart des procédés classiques doivent réaliser les soudures sur quatre épaisseurs de film au niveau des soufflets latéraux.The method according to the present invention has the fundamental advantage of limiting the welds 184, 182 and 186 to two film thicknesses, in particular at the place of fixing the closure profiles 170, whereas most of the conventional methods must carry out the welds on four film thicknesses at the side bellows.
Bien entendu, la présente invention n'est pas limitée au mode de réalisation qui vient d'être décrit, mais s'étend à toutes variantes conformes à la définition donnée dans les revendications annexes.Of course, the present invention is not limited to the embodiment which has just been described, but extends to all variants conforming to the definition given in the appended claims.
Par exemple on peut réaliser des sachets à l'aide d'un film du type illustré sur la figure 7 comprenant des encoches 150, 160 et des profilés de fermeture 170, sans diriger ce film sur une machine de formation, remplissage et fermeture comme indiqué précédemment. Le film est alors conformé à l'état tubulaire par tout moyen classique approprié.For example, it is possible to make sachets using a film of the type illustrated in FIG. 7 comprising notches 150, 160 and closure profiles 170, without directing this film on a forming, filling and closing machine as indicated. previously. The film is then shaped into the tubular state by any suitable conventional means.
Dans le cadre de la présente invention le film 100 peut faire l'objet de nombreuses variantes. Il s'agit de préférence d'un film thermoplastique. Cependant l'invention peut s'étendre à tout film souple susceptible de constituer un sachet d'emballage.In the context of the present invention, the film 100 can be the subject of numerous variants. It is preferably a thermoplastic film. However, the invention can extend to any flexible film capable of constituting a packaging sachet.
Par ailleurs, l'homme de l'art comprendra que si dans le cas illutré sur la figure 5 où les bords longitudinaux 152, 154, 162, 164 des encoches 150 et 160 coïncident avec les lignes de pliage 111, 115, 121 et 125, les soudures 184a et 186a sont réalisées sur deux épaisseurs de film, en revanche lorsque les bords longitudinaux 152, 154, 162, 164 des encoches 150 et 160 sont formées en retrait des lignes de pliage 111, 115, 121, 125, les soudures 184a, 186a sont réalisées au moins en partie dans quatre épaisseurs superposées de film. Il en est de même pour une partie d'extrémité des soudures transversales 180, 182. Les soudures 184a, 186a peuvent d'ailleurs être réalisées au moins partiellement en retrait des lignes de pliage 111, 115, 121, 125 comme illustré sur la figure 9. La variante de réalisation des encoches illustrées sur la figure 5bis permet d'améliorer l'étanchéité latérale des sachets.Furthermore, those skilled in the art will understand that if in the case illustrated in FIG. 5 where the longitudinal edges 152, 154, 162, 164 of the notches 150 and 160 coincide with the fold lines 111, 115, 121 and 125 , the welds 184a and 186a are carried out on two thicknesses of film, on the other hand when the longitudinal edges 152, 154, 162, 164 of the notches 150 and 160 are formed set back from the fold lines 111, 115, 121, 125, the welds 184a, 186a are produced at least in part in four superimposed thicknesses of film. It is the same for an end part of the transverse welds 180, 182. The welds 184a, 186a can moreover be produced at least partially behind the fold lines 111, 115, 121, 125 as illustrated in the figure. 9. The variant embodiment of the notches illustrated in FIG. 5a makes it possible to improve the lateral tightness of the bags.
