Description

Procédé et machine de fixation d'une bande élastique sur une pochette de classement et la pochette obtenue par ce procédé Method and machine for attaching an elastic band to a filing pocket and the pocket obtained by this process
L'invention concerne un procédé de fixation des extrémités d'une bande élastique souple en tension sur une pochette de classement afin de verrouiller la fermeture de celle-ci, ainsi qu'une machine de mise en oeuvre dudit procédé et la pochette ainsi réalisée.The invention relates to a method of fixing the ends of a flexible elastic band in tension on a filing pocket in order to lock the closure thereof, as well as a machine for implementing said process and the pocket thus produced.
En général, la pochette de classement concernée est constituée d'une feuille en matière synthétique semi-rigide qui, en position ouverte, se présente sous une forme généralement rectangulaire et est constituée de deux couvertures liées l'une à l'autre par au moins une ligne de pliage permettant le rabat d'une couverture sur l'autre. Cette feuille peut également comporter une deuxième ligne de pliage délimitant ainsi un dos entre les deux couvertures. En outre, chacune des couvertures peut présenter un ou plusieurs rabats latéraux ou d'extrémité.In general, the classification pocket concerned consists of a semi-rigid plastic sheet which, in the open position, is in a generally rectangular shape and consists of two covers linked to each other by at least a fold line allowing the flap from one cover to the other. This sheet may also include a second fold line thus delimiting a back between the two covers. In addition, each of the covers may have one or more side or end flaps.
L'une des couvertures de la pochette est porteuse de la bande élastique et, à cet effet, présente des orifices au travers desquels est enfilée la bande élastique. Ainsi, à proximité d'un bord libre opposé à la zone de pliage, la couverture présente deux orifices sensiblement équidistants des coins de la couverture, appelés orifices de passage. Par ailleurs, le long des deux bords de la couverture adjacents au bord libre sont ménagés deux orifices dits de fixation, en général symétriques aux orifices de passage par rapport à la bissectrice des angles des coins de la couverture.One of the covers of the pocket carries the elastic band and, for this purpose, has holes through which the elastic band is threaded. Thus, near a free edge opposite the folding zone, the cover has two orifices substantially equidistant from the corners of the cover, called through orifices. Furthermore, along the two edges of the cover adjacent to the free edge are formed two so-called fixing orifices, generally symmetrical to the orifices of passage with respect to the bisector of the corners of the corners of the cover.
Ces orifices sont destinés à accueillir une bande élastique souple de telle sorte qu'une fois la pochette fermée, c'est-à-dire la couverture porteuse de la bande souple élastique rabattue sur la seconde couverture, ladite bande apparait à chaque coin de ladite couverture entre un orifice de passage et un orifice de fixation et permet le verrouillage de la fermeture de la pochette.These orifices are intended to accommodate a flexible elastic band so that once the pouch is closed, that is to say the cover carrying the elastic flexible band folded over the second cover, said band appears at each corner of said cover between a passage orifice and a fixing orifice and allows the locking of the pouch closure.
Le montage de cette bande élastique s'opère de la manière suivante : une première extrémité de la bande est introduite au travers de l'un des orifices de fixation depuis la face intérieure de la couverture vers sa face extérieure, puis cette extrémité de la bande est introduite au travers de l'orifice de passage contigu de telle sorte que la bande élastique s'étend transversalement sur la face extérieure entre l'orifice d'introduction et l'orifice de passage. Ensuite, la bande élastique est introduite dans le second orifice de passage depuis la face intérieure vers la face extérieure de la couverture d'où elle est introduite ensuite au travers du second orifice de fixation depuis la face extérieure vers la face intérieure de la couverture. Les extrémités de ladite bande sont alors fixées sur la couverture.The mounting of this elastic band takes place as follows: a first end of the band is introduced through one of the fixing holes from the inside of the cover to its outside, then this end of the band is introduced through the contiguous passage orifice so that the elastic band extends transversely on the outside face between the introduction orifice and the passage orifice. Then, the elastic band is introduced into the second passage orifice from the internal face towards the external face of the cover, from where it is then introduced through the second fixing orifice from the external face towards the internal face of the cover. The ends of said strip are then fixed to the cover.
En général, on met en place des rivets creux sur les orifices de fixation et de passage afin de les renforcer. Ces rivets permettent également, au niveau des orifices de fixation, de fixer les extrémités de la bande élastique en la pinçant contre la périphérie de l'orifice de fixation. Le montage de la bande élastique décrit ci-dessus peut s'effectuer de manière manuelle. Cependant, un montage manuel présente de nombreux inconvénients et en particulier, il peut se révéler dangereux pour le manutentionnaire notamment lors de la mise en place des rivets et, en outre, il ne permet pas une productivité élevée.In general, hollow rivets are put in place on the fixing and passage orifices in order to reinforce them. These rivets also make it possible, at the level of the fixing holes, to fix the ends of the elastic band by pinching it against the periphery of the fixing hole. The assembly of the elastic band described above can be done manually. However, manual assembly has many drawbacks and in particular, it can prove to be dangerous for the handler, in particular when setting the rivets and, moreover, it does not allow high productivity.
Le brevet FR-B-2 503 803 propose un procédé de fixation automatique des extrémités d'une bande souple par des rivets dans les orifices de fixation. Ce procédé fait appel à un système de pinces mécaniques qui permettent l'introduction des extrémités de la bande souple élastique par les orifices de passage et l'amenée desdites extrémités aux orifices de fixation où l'extrémité de la bande est rabattue mécaniquement au moment de la pose du rivet qui permet sa fixation.Patent FR-B-2 503 803 proposes a method for automatically fixing the ends of a flexible strip by rivets in the fixing orifices. This process uses a system of mechanical clamps which allow the introduction of the ends of the flexible elastic band through the passage openings and the supply of said ends to the fixing orifices where the end of the band is folded down mechanically at the time of the installation of the rivet which allows its fixing.
Ce type de fixation nécessite obligatoirement la mise en place de rivet afin de fixer les extrémités de la bande élastique. Or, les matériaux synthétiques utilisés pour réaliser les pochettes présentent des qualités mécaniques suffisantes pour ne plus nécessiter la pose de rivet de renforcement au niveau des orifices de passage et de fixation. Dans un souci de simplification et d'économie du procédé de fixation de la bande élastique, il convient donc de pouvoir s'affranchir de la présence de rivets.This type of fixing necessarily requires the installation of a rivet in order to fix the ends of the elastic band. However, the synthetic materials used to make the pockets have sufficient mechanical qualities to no longer require the installation of reinforcing rivets at the passage and fixing orifices. For the sake of simplification and economy of the method of fixing the elastic band, it is therefore necessary to be able to overcome the presence of rivets.
Dans ce but, l'invention propose un procédé de fixation des extrémités d'une bande élastique sur une couverture de pochette dans lequel l'enfilage de ladite bande au travers des orifices de passage et de fixation prévus dans la couverture peut être réalisé mécaniquement et dans lequel la fixation des extrémités de la bande élastique mise en place peut être réalisée sans qu'il soit nécessaire d'utiliser un rivet ou tout autre élément complémentaire. A cet effet, l'invention a pour objet un procédé de fixation des extrémités d'une bande élastique sur une pochette en matière synthétique du type comportant deux couvertures reliées entre elle par au moins une ligne de 5 pliage, ladite bande élastique constituant le moyen de verrouillage de la fermeture de la pochette par rabat d'une couverture sur l'autre, caractérisé en ce que la fixation des extrémités de la bande élastique est réalisée par soudage par ultrasons, la bande élastique comprenant un 10 matériau propre à être soudé par ultrasons sur la matière constitutive de la pochette.To this end, the invention provides a method of fixing the ends of an elastic band on a cover of a pocket in which the threading of said band through the passage and fixing orifices provided in the cover can be carried out mechanically and wherein the fixing of the ends of the elastic band put in place can be carried out without the need to use a rivet or any other complementary element. To this end, the subject of the invention is a method of fixing the ends of an elastic band to a pouch of synthetic material of the type comprising two covers linked together by at least one fold line, said elastic band constituting the means for locking the closure of the pouch by flap from one cover to the other, characterized in that the ends of the elastic band are fixed by ultrasonic welding, the elastic band comprising a material suitable for being welded by ultrasound on the material of the pouch.
Ainsi, selon l'invention, il n'est plus nécessaire de mettre en place des rivets pour assurer la fixation de 15 ladite bande élastique.Thus, according to the invention, it is no longer necessary to install rivets to secure said elastic band.
De préférence, la pochette est en polypropylène. Avantageusement, la bande élastique est constituée d'au moins une bande ou de fils enrobés dans du polypropylène. 20Preferably, the pouch is made of polypropylene. Advantageously, the elastic band consists of at least one band or of threads coated in polypropylene. 20
L'invention concerne également une machine pour la mise en oeuvre du procédé et une pochette dans laquelle la bande élastique est fixée sur une des couvertures de la pochette par soudage par ultrasons.The invention also relates to a machine for implementing the method and to a pouch in which the elastic band is fixed to one of the covers of the pouch by ultrasonic welding.

A titre d'exemple, on réalise la fixation d'une bande élastique en tant que moyen de verrouillage de la fermeture d'une pochette de classement. Cette pochette est constituée d'une feuille en polypropylène généralement rectangulaire qu'une ligne de pliage sépare en deux couvertures rabattables l'une sur l'autre et dont l'une peut être prolongée par un rabat d'extrémité.For example, the fixing of an elastic band is carried out as a means of locking the closure of a filing pocket. This pocket consists of a generally rectangular polypropylene sheet which a fold line separates into two covers which can be folded one over the other and one of which can be extended by an end flap.
L'une des couvertures, non pourvue d'un rabat de prolongement d'extrémité, comporte deux orifices de passage A et B le long de son bord libre longitudinal ainsi qu'un orifice C, D dit de fixation situé le long de chaque bord latéral de ladite couverture comme cela est bien connu.One of the covers, not provided with an end extension flap, has two through holes A and B along its longitudinal free edge as well as a hole C, D said fixing located along each edge lateral of said cover as is well known.
La machine représentée à la figure 1 comporte, de préférence, un support sur lequel est mise en place la couverture 4, des moyens de guidage propres à guider la bande élastique, amenée par une paire de rouleaux 2, au travers de l'orifice A depuis une première face de la couverture 4 vers la seconde face puis au travers de l'orifice B de la seconde face vers la première face de la couverture, un dispositif de coupe de la bande élastique 1, des moyens d'amenée propres à amener les extrémités l', l' ' de la bande élastique 1 vers les orifices de fixation C, D au travers desquels les extrémités sont enfilées et des moyens propres à assurer la fixation desdites extrémités par soudage par ultrasons.The machine shown in FIG. 1 preferably includes a support on which the cover 4 is placed, guide means suitable for guiding the elastic band, brought by a pair of rollers 2, through the orifice A from a first face of the cover 4 towards the second face then through the orifice B of the second face towards the first face of the cover, a device for cutting the elastic band 1, supply means suitable for bringing the ends l ', l' of the elastic band 1 towards the fixing orifices C, D through which the ends are threaded and means suitable for securing said ends by ultrasonic welding.
La couverture 4 pourvue des orifices de fixation C, D et de passage A, B est mise en place sur le support présentant une face inférieure et une face supérieure. La face inférieure correspond à la face extérieure de la couverture 4 et la face supérieure correspond à la face intérieure de la couverture 4, lorsque la pochette est fermée.The cover 4 provided with fixing holes C, D and passage A, B is placed on the support having a lower face and an upper face. The lower face corresponds to the outer face of the cover 4 and the upper face corresponds to the inner face of the cover 4, when the cover is closed.
Les moyens de guidage de la bande élastique 1 sont constitués par un canal d'aspiration au travers duquel la bande élastique 1 est aspirée. Le canal comporte une première section 5 permettant de guider la bande élastique 1 le long de la face extérieure de la couverture 4 jusqu'au premier orifice de passage A, une deuxième section 6 guidant, le long de la face intérieure de la couverture 4, la bande élastique 1 depuis ledit premier orifice de passage A jusqu'au second orifice de passage B et une troisième section 7 guidant la bande élastique 1 de nouveau le long de la face extérieure de la couverture 4. Ainsi, pour passer de la première section 5 à la deuxième section 6 dudit canal d'aspiration, la bande élastique 1 est guidée au travers du premier orifice de passage A et pour passer de la deuxième section 6 à la troisième section 7 dudit canal, la bande élastique 1 est guidée au travers du second orifice de passage B.The means for guiding the elastic band 1 are constituted by a suction channel through which the elastic band 1 is sucked. The channel has a first section 5 for guiding the elastic band 1 along the outer face of the cover 4 to the first passage orifice A, a second section 6 guiding, along the inside face of the cover 4, the elastic band 1 from said first passage orifice A to the second passage orifice B and a third section 7 guiding the elastic band 1 again along the external face of the cover 4. Thus, to pass from the first section 5 to the second section 6 of said suction channel, the elastic band 1 is guided through the first passage orifice A and to pass from the second section 6 to the third section 7 of said channel, the elastic band 1 is guided through the second passage orifice B.
La bande élastique 1 est aspirée dans le canal d'aspiration jusqu'à ce que son extrémité libre menante l' parvienne à l'extrémité du canal 7. Des tiges de serrage 9 sont alors prévues pour maintenir en place la bande élastique 1 tandis qu'un dispositif de coupe 3, prévu à l'entrée du canal d'aspiration est actionné et crée la seconde extrémité l' ' de la bande 1.The elastic band 1 is sucked into the suction channel until its free leading end reaches it at the end of the channel 7. Clamping rods 9 are then provided to hold the elastic band 1 in place while 'A cutting device 3, provided at the entrance to the suction channel is actuated and creates the second end 1' 'of the strip 1.
Afin d'amener les extrémités l' et l'' de la bande élastique 1 en regard des orifices de fixation C et D de la couverture, les extrémités de la première section 5 et de la troisième section 7 du canal d'aspiration, en regard respectivement des orifices de passage A et B, sont maintenues fixes tandis que leurs extrémités opposées peuvent pivoter autour de l'axe passant au travers desdits orifices de passage A et B jusqu'à ce que lesdites extrémités opposées soient en regard des orifices de fixation C et D.In order to bring the ends l 'and l' of the elastic band 1 opposite the fixing orifices C and D of the cover, the ends of the first section 5 and of the third section 7 of the suction channel, in look respectively at the passage openings A and B, are kept fixed while their opposite ends can pivot around the axis passing through said passage openings A and B until said opposite ends are opposite the fixing holes C and D.
Par ailleurs, des moye: sont prévus pour gi jer lesdites extrémités 1 • et 1 ' ' de a bande élastique 1 au travers des orifices de fixation C et D depuis la face extérieure de la couverture 4 vers sa face intérieure. De préférence, ces moyens sont constitués par des buses à air comprimé. Les extrémités 1 ' et 1 ' ' de la bande élastique sont ensuite rabattues et soudées par ultrasons sur la face intérieure de la couverture 4 à l'aide de deux têtes de soudage par ultrasons (non représentées).In addition, hubs: are provided for gi jer said ends 1 • and 1 'of an elastic band 1 through the fixing holes C and D from the outer face of the cover 4 to its inner face. Preferably, these means consist of compressed air nozzles. The ends 1 'and 1''of the elastic band are then folded down and welded by ultrasound to the inside of the cover 4 using two ultrasonic welding heads (not shown).
La pochette étant en polypropylène, la bande élastique 1 est constituée d'au moins une bande ou de fils enrobés dans du polypropylène afin de permettre le soudage par ultrasons sur ladite pochette. The pouch being made of polypropylene, the elastic band 1 consists of at least one band or of wires coated in polypropylene in order to allow ultrasonic welding on said pouch.
