Abstract

The method involves forming a packaging bag in a movement film and welding opening and closing sections on the film, where the sections comprise a set of actuating cursors (4). A cut-out is made in the sections, where the cut-out has a length that is greater than the width of each cursor. One of the cursors is ejected from the sections by the cut-out, when the cursors are not found on the sections. A cut-out of the sections is performed regularly along the sections, where each cut-out is separated from the other cut-outs by a distance that is multiple of a step (6) of the bag.

Description

DOMAINE TECHNIQUE GENERALGENERAL TECHNICAL FIELD

La présente invention concerne la fabrication de sachets d'emballage comportant des profilés de fermeture et d'ouverture munis de curseurs.The present invention relates to the manufacture of packaging bags comprising closure and opening profiles provided with sliders.

ETAT DE L'ARTSTATE OF THE ART

On connaît de nombreux procédés de fabrication de sachets d'emballage comportant des profilés de fermeture et d'ouverture munis de curseurs.Numerous processes are known for manufacturing packaging bags comprising closure and opening profiles provided with sliders.

La figure 1 montre que certains de ces procédés comportent une étape consistant à former des sachets 2 dans un film 1 en défilement, et une étape consistant à souder, sur les sachets 2 ainsi formés, des profilés 3 de fermeture et d'ouverture comportant une série de curseurs 4 d'actionnement.FIG. 1 shows that some of these methods comprise a step of forming bags 2 in a moving film 1, and a step of welding, on the bags 2 thus formed, 3 closing and opening profiles comprising a series of actuators 4 sliders.

Les profilés 3 de fermeture et d'ouverture comportent en général des profils complémentaires, et chaque curseur 4 permet d'ouvrir ou de fermer un sachet 2 en mettant en coopération ou non les profilés lors de son déplacement le long des profilés.The closing and opening profiles 3 generally comprise complementary profiles, and each slider 4 makes it possible to open or close a bag 2 by putting the sections in cooperation or not when moving along the profiles.

Sur certaines machines de conditionnement, il est préférable de souder les profilés 3 en continu.On certain packaging machines, it is preferable to weld the sections 3 continuously.

Etant données les variations de longueur de pas 5 des curseurs 4 sur les profilés 3 et les variations de longueur de pas 6 des sachets lors de la fabrication, il est nécessaire de recaler chaque curseur 4 dans le pas désiré 6 du sachet 2.Given the variations in the length of steps 5 of the sliders 4 on the sections 3 and the variations of step length 6 of the bags during manufacture, it is necessary to reset each slider 4 in the desired step 6 of the bag 2.

A cet effet, on soude sur les sachets 2 des profilés 3 munis de curseurs 4 dont le pas 5 est légèrement inférieur au pas 6 des sachets 2, de sorte qu'avec les tolérances sur les pas 5 et 6, la longueur 40 maximale d'un profilé muni d'un curseur 4 soit toujours inférieure au pas 6 minimal d'un sachet 2.For this purpose, it is welded on the bags 2 of the profiles 3 provided with sliders 4 whose pitch 5 is slightly less than the pitch 6 of the bags 2, so that with the tolerances on the steps 5 and 6, the maximum length 40 d a section provided with a slider 4 is always smaller than the minimum pitch 6 of a bag 2.

Cependant, comme le montre la figure 2, en repositionnant le curseur 4 au pas 6 du sachet 2, au bout de la fabrication de n sachets, on se retrouve avec deux curseurs 4 sur un sachet 2 de rand n. On a en effet une largeur 6' de sachet s'écartant du pas 6 souhaité des sachets.However, as shown in FIG. 2, by repositioning the slider 4 at step 6 of the bag 2, at the end of the production of n bags, one gets found with two sliders 4 on a bag 2 rand n. Indeed, there is a width 6 'of sachet deviating from the desired step 6 of the sachets.

Actuellement, on marque le sachet 2 de rang n comme défectueux et on l'éjecte de la ligne de production.Currently, the bag 2 of rank n is marked as defective and is ejected from the production line.

Cela crée une rupture dans la chaîne de production que l'on souhaite par ailleurs continue.This creates a break in the production line that one wishes otherwise continues.

Cela cause également la perte de l'ensemble du sachet, et donc un surcoût de fabrication si cela se reproduit souvent.This also causes the loss of the entire bag, and therefore an additional manufacturing cost if it happens often.

PRESENTATION DE L'INVENTIONPRESENTATION OF THE INVENTION

L'invention propose de pallier au moins un des inconvénients de l'art antérieur.The invention proposes to overcome at least one of the disadvantages of the prior art.

A cet effet, on propose selon l'invention un procédé de fabrication de sachets d'emballage comportant une étape consistant à :

  • former au moins un sachet dans un film en défilement,
  • souder, sur le film en défilement, des profilés de fermeture et d'ouverture comportant une série de curseurs d'actionnement,
  • effectuer au moins une découpe dans les profilés, la longueur de la découpe étant supérieure à la longueur de chaque curseur,
    caractérisé en ce qu'il comporte une étape consistant à :
  • éjecter un curseur des profilés par une découpe.
For this purpose, it is proposed according to the invention a method of manufacturing packaging bags comprising a step consisting in:
  • forming at least one sachet in a moving film,
  • welding, on the running film, closure and opening profiles comprising a series of actuating sliders,
  • at least one cut in the profiles, the length of the cut being greater than the length of each slider,
    characterized in that it comprises a step of:
  • to eject a slider of the profiles by a cut.

L'invention est avantageusement complétée par les caractéristiques suivantes, prises seules ou en une quelconque de leur combinaison techniquement possible :

  • l'étape de découpe des profilés est effectuée régulièrement le long des profilés, chaque découpe étant séparée des autres découpes d'une distance multiple d'un pas des sachets ;
  • le procédé comporte en outre une étape consistant à positionner un curseur près d'une découpe sur les profilés ;
  • l'étape d'éjection est effectuée lorsqu'il y a plus d'un curseur sur les profilés pour un sachet.
The invention is advantageously completed by the following features, taken alone or in any of their technically possible combination:
  • the step of cutting profiles is performed regularly along the profiles, each cut being separated from other cuts a distance multiple of one step of the bags;
  • the method further comprises a step of positioning a slider near a cutout on the profiles;
  • the ejection step is performed when there is more than one slider on the profiles for a bag.

L'invention présente de nombreux avantages.The invention has many advantages.

L'invention permet de n'avoir qu'un seul curseur d'actionnement sur un sachet.The invention makes it possible to have only one actuating slider on a bag.

Elle permet d'éviter une rupture dans la chaîne de production et donc un surcoût de fabrication. Seul le curseur est perdu, et non pas l'ensemble du sachet comme c'est le cas dans l'art antérieur.It avoids a break in the production line and therefore an additional manufacturing cost. Only the cursor is lost, and not the entire bag as is the case in the prior art.

L'éjection d'un curseur surnuméraire sur un sachet s'effectue facilement.Ejecting a supernumerary cursor on a bag is easy.

La découpe des profilés permet de ne pas avoir de surépaisseur au niveau de la zone de soudage latérale des sachets. Le soudage s'effectue donc de manière plus efficace et l'étanchéité du sachet est renforcée.The cutting of the profiles makes it possible to have no extra thickness in the area of lateral welding of the bags. The welding is therefore performed more effectively and the sealing of the bag is reinforced.

DESCRIPTION DETAILLEEDETAILED DESCRIPTION

Classiquement, un procédé de fabrication de sachets 2 d'emballage selon l'invention comporte une étape consistant à former au moins un sachet 2 dans un film 1 en défilement et à souder, sur le film en défilement, des profilés 3 de fermeture et d'ouverture comportant une série de curseurs 4 d'actionnement. Une telle étape est conforme à ce qui a été divulgué en référence à la figure 1 et n'est pas décrite ici par souci de concision.Conventionally, a method of manufacturing packaging bags 2 according to the invention comprises a step consisting in forming at least one bag 2 in a film 1 in scrolling and welding, on the running film, profiles 3 closure and d opening comprising a series of sliders 4 actuation. Such a step is in accordance with what has been disclosed with reference to Figure 1 and is not described here for the sake of brevity.

De même, les profilés 3 et les curseurs 4 sont classiques et ne sont décrits en détail dans la présente description. Les curseurs 4 sont présents sur les profilés 3 selon un pas 5.Likewise, the profiles 3 and the sliders 4 are conventional and are not described in detail in the present description. The cursors 4 are present on the profiles 3 according to a step 5.

Après le soudage des profilés sur le film en défilement, le procédé de fabrication comporte une étape de remplissage des sachets et une étape de soudage latéral pour individualiser les sachets 2. L'étape de remplissage et de soudage latérale peuvent être effectuées dans n'importe quel ordre l'une par rapport à l'autre, et être effectuées sur une même machine où sur une machine différente.After the welding of the profiles on the moving film, the manufacturing method comprises a step of filling the bags and a lateral welding step to individualize the bags 2. The step of filling and lateral welding can be carried out in any which order relative to each other, and be performed on the same machine or on a different machine.

On comprend que le soudage latéral est effectué selon un pas 6 des sachets, mais du fait des tolérances notamment, les sachets 2 ont une largeur 6' qui peut être différente du pas souhaité 6.It is understood that the lateral welding is carried out at a step 6 of the bags, but because of the particular tolerances, the bags 2 have a width 6 'which may be different from the desired pitch 6.

La figure 3 montre que le procédé comporte une étape consistant à effectuer, préférentiellement avant l'étape de remplissage et l'étape de soudage latéral, au moins une découpe 7 dans les profilés 3 soudés sur le film en défilement.FIG. 3 shows that the method comprises a step of carrying out, preferably before the filling step and the lateral welding step, at least one cutout 7 in the sections 3 welded to the moving film.

La figure 3 montre également, en superposant verticalement les n+3 sachets 2 successifs, que l'étape de découpe des profilés 3 est effectuée régulièrement le long des profilés. Chaque découpe 7 est séparée des autres découpes 7 d'une distance multiple d'un pas 6 des sachets 2.FIG. 3 also shows, by vertically superimposing the n + 3 successive bags 2, that the cutting step of the sections 3 is carried out regularly along the profiles. Each cutout 7 is separated from the other cuts 7 by a distance multiple of one step 6 of the bags 2.

Très préférentiellement, la découpe 7 correspond à une zone de soudage latéral. Ainsi, comme le montre la figure 4, un sachet 2 fabriqué grâce au procédé selon l'invention comporte une découpe 7 à chaque extrémité des profilés 3. La découpe 7 des profilés 3 permet de ne pas avoir de surépaisseur au niveau de la zone 20 de soudage latéral des sachets. Le soudage s'effectue donc de manière plus efficace et l'étanchéité du sachet est renforcée.Very preferably, the cutout 7 corresponds to a lateral welding zone. Thus, as shown in Figure 4, a bag 2 manufactured by the method according to the invention comprises a cutout 7 at each end of the profiles 3. The cutout 7 of the profiles 3 allows to have no extra thickness at the zone 20 lateral welding of the bags. The welding is therefore performed more effectively and the sealing of the bag is reinforced.

Le procédé comporte en outre une étape consistant à positionner chaque curseur 4 sur les profilés 3. Préférentiellement, le curseur 4 est positionné dans une zone de repositionnement 60 proche d'une découpe 7.The method further comprises a step of positioning each slider 4 on the profiles 3. Preferably, the slider 4 is positioned in a repositioning zone 60 near a cutout 7.

La figure 3 montre que, du fait des variations du pas 6 des sachets causant une largeur 6' différente des sachets entre eux, ainsi que des variations du pas 5 des curseurs 4, il se produit que plusieurs curseurs 4 peuvent être positionnés sur les profilés 3 pour un même sachet 2. Il s'agit par exemple du sachet 2 de rang n sur la figure 3.FIG. 3 shows that, because of the variations of the pitch 6 of the sachets causing a different width 6 'of the sachets to one another, as well as variations of the pitch 5 of the cursors 4, several cursors 4 can be positioned on the profiles. 3 for the same bag 2. This is for example the bag 2 of rank n in Figure 3.

Dans ce cas, le procédé comporte en outre une étape consistant à éjecter un curseur 4 des profilés 3 par une découpe 7. Du fait de l'éjection, il n'y qu'un seul curseur d'actionnement sur un sachet.In this case, the method further comprises a step of ejecting a slider 4 of the sections 3 by a cutout 7. Due to the ejection, there is only one actuating slider on a bag.

L'étape d'éjection permet d'éviter une rupture dans la chaîne de production et donc un surcoût de fabrication. Seul le curseur est perdu, et non pas l'ensemble du sachet comme c'est le cas dans l'art antérieur.The ejection step avoids a break in the production line and therefore a manufacturing overhead. Only the cursor is lost, and not the entire bag as is the case in the prior art.

L'éjection d'un curseur surnuméraire sur un sachet s'effectue facilement. En effet, la longueur 70 de la découpe 7 est supérieure à la longueur 40 de chaque curseur 4.Ejecting a supernumerary cursor on a bag is easy. Indeed, the length 70 of the cutout 7 is greater than the length 40 of each slider 4.
