Description

PILE DE SACS AVEC FERMETURE A GLISSIERE ET CURSEUR STACK OF BAGS WITH ZIPPER AND SLIDER
L'invention concerne les sacs refermables au moyen de profilés, et leur fabrication.The invention relates to resealable bags by means of profiles, and their manufacture.
On connaît des procédés pour fabriquer des sacs en matière plastique présentant à une embouchure deux profilés et un curseur coulissant sur ceux-ci. Lors de la fabrication, le curseur est situé à une distance prédéterminée des extrémités des profilés pour ne pas interférer avec des opérations de soudure et de coupe effectuées. Toutefois, lorsque les sacs sont disposés les uns sur les autres, les curseurs viennent s'empiler les uns sur les autres en générant une hauteur de pile beaucoup plus importante au niveau des curseurs que sur le reste des sacs. Ainsi, le stockage des sacs se trouve compliqué par le volume des piles et leur instabilité. En particulier, il est difficile de constituer des rouleaux ou des piles comportant un nombre important de sacs .Processes are known for manufacturing plastic bags having at a mouth two profiles and a sliding cursor thereon. During manufacture, the cursor is located at a predetermined distance from the ends of the profiles so as not to interfere with welding and cutting operations carried out. However, when the bags are placed on top of each other, the sliders stack on top of each other, generating a much higher stack height at the level of the sliders than on the rest of the bags. Thus, the storage of the bags is complicated by the volume of the batteries and their instability. In particular, it is difficult to form rolls or stacks comprising a large number of bags.
Le document US-5 682 730 montre une pile de sacs présentant une série inférieure de sacs successifs dans laquelle la distance a une première valeur constante de sorte que les curseurs sont empilés les uns sur les autres près d'une extrémité des profilés, et une série supérieure de sacs successifs dans laquelle la distance a une deuxième valeur constante, différente de la première valeur, les curseurs de cette deuxième série étant empilés près de l'autre extrémité des profilés. Ainsi, les deux piles de curseurs n'interfèrent pas entre elles et s'étendent presque à la même hauteur, ce qui diminue très sensiblement la hauteur de la pile. Cette disposition est rendue possible par la souplesse des sacs. Toutefois, la hauteur de la pile de sacs demeure relativement importante. Un but de l'invention est d'améliorer le stockage des sacs notamment pour réaliser des rouleaux ou piles de très nombreux sacs.Document US Pat. No. 5,682,730 shows a stack of bags having a lower series of successive bags in which the distance has a first constant value so that the sliders are stacked on each other near one end of the profiles, and a upper series of successive bags in which the distance has a second constant value, different from the first value, the sliders of this second series being stacked near the other end of the profiles. Thus, the two stacks of sliders do not interfere with each other and extend almost to the same height, which very significantly decreases the height of the stack. This arrangement is made possible by the flexibility of the bags. However, the height of the stack of bags remains relatively large. An object of the invention is to improve the storage of bags, in particular for making rolls or stacks of very many bags.
En vue de la réalisation de ce but, on prévoit selon l'invention un ensemble d'au moins trois sacs consécutifs dans une succession, comprenant chacun deux profilés et un curseur situé à une distance d'une extrémité des profilés, les profilés et les curseurs étant identiques entre les sacs, dans lequel les distances sont différentes entre les sacs dans chaque paire de sacs adjacents.In order to achieve this goal, there is provided according to the invention a set of at least three consecutive bags in a succession, each comprising two sections and a slider located at a distance from one end of the sections, the sections and the sliders being identical between the bags, in which the distances are different between the bags in each pair of adjacent bags.
Ainsi, on obtient une disposition des curseurs différente de celle connue précitée et permettant de stocker les sacs avec un volume différent et plus stable et par exemple en une pile moins haute. Par exemple, les curseurs pourront être décalés relativement d'une demi- longueur de curseur. Dès lors, l'empilement des sacs provoque une légère torsion des profilés, et une inclinaison des curseurs se couchant les uns sur les autres. On réduit ainsi le volume de la pile au niveau des curseurs.Thus, a different arrangement of the sliders is obtained from that known above and allowing the bags to be stored with a different and more stable volume and for example in a lower stack. For example, the cursors can be offset relatively by half a cursor length. Consequently, the stacking of the bags causes a slight twisting of the profiles, and an inclination of the sliders lying on top of each other. This reduces the volume of the battery at the level of the sliders.
Préférentielle ent, les distances diffèrent d'au moins une dimension des curseurs parallèlement aux profilés . Ainsi, on peut empiler les sacs les uns sur les autres avec les profilés contigus sans que les curseurs ne viennent s'empiler en interférant mutuellement, les curseurs se disposant les uns à côté des autres. Dès lors, le volume de l'ensemble des sacs correspond sensiblement à celui généré par les parois et les profilés, et est donc considérablement réduit. Dès lors, la pile de sacs est stable.Preferably, the distances differ by at least one dimension of the sliders parallel to the profiles. Thus, the bags can be stacked on top of each other with the contiguous profiles without the sliders stacking up, interfering with each other, the sliders being placed next to each other. Consequently, the volume of all the bags corresponds substantially to that generated by the walls and the profiles, and is therefore considerably reduced. The stack of bags is therefore stable.
Avantageusement, les distances sur les sacs adjacents varient suivant une progression monotone. Ainsi, on peut empiler un très grand nombre de sacs en optimisant le volume disponible pour les curseurs sans risquer d'interférence, même entre des curseurs de sacs non consécutifs. Avantageusement, les distances varient d'un incrément constant.Advantageously, the distances on the adjacent bags vary according to a monotonous progression. Thus, a very large number of bags can be stacked while optimizing the volume available for the sliders without risking interference, even between non-consecutive bag sliders. Advantageously, the distances vary by a constant increment.
Avantageusement, les sacs sont disposés avec leurs profilés contigus.Advantageously, the bags are arranged with their contiguous profiles.
Avantageusement, l'ensemble constitue un rouleau de sacs.Advantageously, the assembly constitutes a roll of bags.
Avantageusement, l'ensemble constitue une pile de sacs .Advantageously, the assembly constitutes a stack of bags.
On prévoit également selon l'invention un procédé de fabrication d'au moins trois sacs comprenant chacun deux profilés et un curseur, les profilés et les curseurs étant identiques entre les sacs, dans lequel on dispose chaque curseur à une distance d'une extrémité des profilés et dans lequel on dispose les curseurs de sorte que les distances sont différentes entre deux sacs successifs quelconques.The invention also provides a method of manufacturing at least three bags each comprising two sections and a slider, the sections and the sliders being identical between the bags, in which each slider is placed at a distance from one end of the profiles and in which we have the sliders so that the distances are different between any two successive bags.
On prévoit encore selon l'invention une installation pour fabriquer des sacs comprenant deux profilés et un curseur, l'installation comprenant des moyens pour disposer le curseur à une distance d'une extrémité des profilés, dans laquelle les moyens sont agencés pour disposer le curseur à des distances différentes sur deux sacs successifs quelconques.According to the invention, there is also provided an installation for manufacturing bags comprising two sections and a slider, the installation comprising means for placing the slider at a distance from one end of the sections, in which the means are arranged for placing the slider at different distances on any two successive bags.
D'autres caractéristiques et avantages de l'invention apparaîtront encore dans la description suivante d'un mode préféré de réalisation donné à titre d'exemple non limitatif. Aux dessins annexés : la figure 1 est une vue partielle en coupe transversale d'un sac au niveau des profilés ; - la figure 2 est une vue en perspective illustrant le principe du positionnement des curseurs de plusieurs sacs d'un ensemble ;Other characteristics and advantages of the invention will become apparent in the following description of a preferred embodiment given by way of nonlimiting example. In the accompanying drawings: Figure 1 is a partial cross-sectional view of a bag at the profiles; - Figure 2 is a perspective view illustrating the principle of positioning the sliders of several bags of an assembly;
- la figure 3 est une vue de face de deux sacs de la figure 2 ;- Figure 3 is a front view of two bags of Figure 2;
- la figure 4 est une vue de face d'un empilement d'un grand nombre de sacs ; et- Figure 4 is a front view of a stack of a large number of bags; and
- la figure 5 est une vue schématique d'une installation selon l'invention. En référence à la figure 1, l'invention met en oeuvre des sacs 2 identiques entre eux, d'un type connu en soi. Le sac 2 en matière plastique comporte deux parois planes rectangulaires 4 disposées bord à bord et soudées l'une à l'autre sur trois de leurs bords pour constituer une poche. Les côtés non soudés forment une embouchure et reçoivent sur leur face intérieure des profilés rectilignes complémentaires 6 constituant une fermeture amovible étanche. Un curseur 8 est monté mobile à coulissement sur les profilés 6 et est conformé, de façon non illustrée mais connue en soi, de sorte que son coulissement dans un sens provoque l'association des profilés 6 pour la fermeture du sac 2 et dans l'autre sens la dissociation des profilés et l'ouverture du sac. En référence à la figure 5, dans le procédé de fabrication de sacs selon l'invention, les sacs 2 sont formés à partir d'une membrane continue 4 et les profilés 6 sont rapportés et soudés au poste 11 sur les sacs en continu avant ou après découpe individuelle des sacs dans la membrane. Les profilés 5 sont rapportés alors qu'ils portent déjà un curseur 8 pour chaque sac, ou bien on rapporte les curseurs 8 après la pose des profilés 6 sur les sacs. La fabrication comprend l'étape de soudure des extrémités 10a, 10b des profilés 6 l'un à l'autre et leur sectionnement au poste 13, qui peut être simultané à l'étape de sectionnement des sacs les uns par rapport aux autres.- Figure 5 is a schematic view of an installation according to the invention. Referring to Figure 1, the invention uses bags 2 identical to each other, of a type known per se. The plastic bag 2 has two rectangular flat walls 4 arranged edge to edge and welded to each other on three of their edges to form a pocket. The non-welded sides form a mouth and receive on their inner face complementary rectilinear profiles 6 constituting a removable waterproof closure. A slider 8 is movably mounted to slide on the sections 6 and is shaped, in a manner not illustrated but known per se, so that its sliding in one direction causes the association of the sections 6 for closing the bag 2 and in the another way is to dissociate the profiles and open the bag. With reference to FIG. 5, in the method of manufacturing bags according to the invention, the bags 2 are formed from a continuous membrane 4 and the profiles 6 are attached and welded at station 11 on the bags continuously before or after individual cutting of the bags in the membrane. The profiles 5 are added while they already carry a slider 8 for each bag, or else the sliders 8 are brought back after the profiles 6 have been placed on the bags. The manufacturing includes the step of welding the ends 10a, 10b of the sections 6 one to the other and their sectioning at station 13, which can be simultaneous with the sectioning of the bags relative to one another.
A un stade ou à un autre de la fabrication après la pose du curseur 8, par exemple durant le sectionnement des profilés 6, un dispositif de positionnement 15 est programmé pour faire coulisser le curseur 8 de chaque sac sur les profilés et le placer à une distance prédéterminée dl, d2 de l'une des extrémités 10a des profilés. Cette distance dl, d2 est prévue pour être différente sur deux sacs 2 quelconques successifs lors de la fabrication. En l'espèce, et en référence à la figure 3, la différence entre dl et d2 est un incrément "i" supérieur à une longueur "1" du curseur 8 parallèlement aux profilés 6. De plus, pour une série donnée de sacs 2, par exemple une série de neuf sacs comme sur la figure 4, la distance "d" subit une variation monotone, à savoir qu'elle ne fait que décroître ou croître (comme c'est le cas ici), en progressant de sac en sac dans la série. L'incrément "i" entre les sacs 2 est ici constant. On veillera de préférence à donner à l'incrément "i" une valeur ne dépassant que de peu la longueur "1" du curseur 8, notamment inférieure à 21, par exemple égale à 1,5 1, afin de pouvoir mettre le plus grand nombre possible de sacs dans une même série sans être gêné par l'autre extrémité 10b des profilés.At one stage or another of the manufacturing after the installation of the cursor 8, for example during the sectioning of the profiles 6, a positioning device 15 is programmed to slide the cursor 8 of each bag on the profiles and place it at a predetermined distance dl, d2 from one of the ends 10a of the profiles. This distance dl, d2 is intended to be different on any two successive bags 2 during manufacture. In this case, and with reference to FIG. 3, the difference between dl and d2 is an increment "i" greater than a length "1" of the cursor 8 parallel to the profiles 6. In addition, for a given series of bags 2 , for example a series of nine bags as in Figure 4, the distance "d" undergoes a monotonous variation, namely that it only decreases or increases (as is the case here), progressing from bag to bag in the series. The increment "i" between the bags 2 is here constant. It will be preferable to give the increment "i" a value which only slightly exceeds the length "1" of the cursor 8, in particular less than 21, for example equal to 1.5 1, in order to be able to set the largest possible number of bags in the same series without being hindered by the other end 10b of the profiles.
A l'issue de cette fabrication, on obtient des sacs 2 dont les curseurs 8 présentent les différences de distance dl, d2 précitées. Les sacs 2 peuvent ainsi être enroulés et empilés en faisant coïncider respectivement les extrémités 10a et 10b des profilés 6, sans que les curseurs 8 n'interfèrent mutuellement dans une même série de sacs, voire même entre des séries de sacs successives, comme les deux séries de neuf sacs de la figure 4. At the end of this manufacture, bags 2 are obtained, the sliders 8 of which have the aforementioned differences in distance dl, d2. The bags 2 can thus be rolled up and stacked by making the ends 10a and 10b of the profiles 6 coincide respectively, without the sliders 8 interfering mutually in the same series of bags, or even between series of bags successive, like the two series of nine bags in Figure 4.
