Description

Dispositif de déploiement d'un emballage plissé pour corps convexes, méthode de mise en oeuvre et procédé de fabrication.Device for deploying a pleated packaging for convex bodies, implementation method and manufacturing method.
L'invention concerne un dispositif de déploiement des plis d'un emballage en film pour corps convexes, par exemple pour sandwiches mais non exclusivement, sa méthode de mise en oeuvre et son procédé de fabrication. Le brevet FR-À-2595666 décrit un emballage plissé pour corps convexes fabriqué à partir du pliage d'un film mince sous forme de plis couchés fixés entre eux à leurs extrémités. De cet emballage plissé a découlé plusieurs emballages brevetés du même genre auxquels peut s'appliquer le dispositif objet de l'invention.The invention relates to a device for deploying the folds of a film packaging for convex bodies, for example for sandwiches but not exclusively, its implementation method and its manufacturing method. The patent FR-À-2595666 describes a pleated package for convex bodies made from the folding of a thin film in the form of coated plies fixed together at their ends. From this pleated packaging resulted several patented packaging of the same kind to which the device object of the invention can be applied.
Quand on n'a pas l'habitude de déployer ce type d'emballage plissé, il est difficile de défaire tous les plis couchés et il arrive qu'on ne puisse faire le tour complet du sandwich avec l'emballage plissé lorsqu'il est déployé à cause d'un nombre de plis couchés non déployés trop important .When you are not used to deploying this type of pleated packaging, it is difficult to undo all the folded folds and sometimes you cannot go around the sandwich with the pleated packaging when it is deployed due to a too large number of folds not deployed deployed.
Le dispositif objet de la présente invention pallie cet inconvénient en permettant à quiconque non averti de déployer l'ensemble des plis couchés de l'emballage plissé autour du corps à emballer.The device object of the present invention overcomes this drawback by allowing anyone who is not aware to deploy all of the folds of the pleated packaging around the body to be packed.
Selon l'invention, on fixe une bande souple dans la partie centrale de l'emballage plissé et dans la direction perpendiculaire aux plis couchés, la fixation de ladite bande sur les plats des plis couchés étant obtenue au moyen d'un produit adhésif ou d'une colle pelable. Ainsi, en tirant sur l'extrémité de ladite bande souple on déploie les plis couchés un par un autour du produit à emballer. Sur les dessins ;According to the invention, a flexible strip is fixed in the central part of the pleated packaging and in the direction perpendicular to the coated folds, the fixing of said strip on the flat of the coated folds being obtained by means of an adhesive or 'peelable glue. Thus, by pulling on the end of said flexible strip, the folds are deployed one by one around the product to be packaged. In the drawings;
La figure 1 représente un emballage plissé suivant l'état de la technique sur lequel on a fixé un dispositif de déploiement des plis selon l'invention.FIG. 1 represents a pleated package according to the state of the art on which a device for deploying the folds according to the invention has been fixed.
La figure 2 montre un sandwich autour duquel on déploie un emballage plissé suivant la figure 1.FIG. 2 shows a sandwich around which a pleated packaging is deployed according to FIG. 1.
La figure 3 représente schématiquement et en perspective un procédé de fabrication connu d'emballages plissés auquel on a adapté un moyen de dépose du dispositif de déploiement suivant l'invention.FIG. 3 shows schematically and in perspective a known method of manufacturing pleated packaging to which a means of removing the deployment device according to the invention has been adapted.
Un emballage connu (fig.l)est réalisé à partir du pliage d'un film mince sous forme de plis couchés 1 fixés entre eux à leurs extrémités 2 et comprenant chacun un plat 3 relativement étroit et un creux 4 relativement profond. La longueur cumulée des plis couchés 1 déployés est égale ou supérieure au périmètre de l'objet convexe à emballer dans la zone couverte par la partie centrale de l'emballage plissé située parallèlement et à égale distance des extrémités 2 des plis cochés et qui correspond généralement à son plus grand périmètre.A known package (fig.l) is produced from the folding of a thin film in the form of coated pleats 1 fixed between them at their ends 2 and each comprising a dish 3 relatively narrow and a relatively deep hollow 4. The cumulative length of the folded plies 1 deployed is equal to or greater than the perimeter of the convex object to be packaged in the area covered by the central part of the pleated packaging located parallel and equidistant from the ends 2 of the checked plies and which generally corresponds at its greatest perimeter.
L'emballage plissé comporte à chaque extrémité une zone sans plis couchés 5 et 6 ne comportant qu'une épaisseur de film permettant de le séparer des autres emballages plissés par simple découpe, suivant le procédé de fabrication adopté. A titre d'exemple, non limitatif, lorsqu'il s'agit d'emballer un sandwich 7 (fig.2) formé à partir de deux demi- pains ronds du genre de ceux produits dans la restauration rapide, de forme sensiblement cylindrique de révolution, les plis couchés 1 de l'emballage plissé sont déployés un par un, dans leur partie centrale 8 en suivant la face cylindrique 9 du sandwich 7, depuis une zone de retenue située au niveau d'une zone sans plis couchés 5 jusqu'à l'autre zone sans plis couchés 6. Au cours du déploiement des plis couchés 1, les bords de l'emballage plissé où les extrémités 2 des plis couchés 1 sont fixées entre elles, se rabattent sur la partie inférieure 11 et supérieure 10 du sandwich 7.The pleated packaging has at each end a zone without coated pleats 5 and 6 comprising only a film thickness allowing it to be separated from the other pleated packaging by simple cutting, according to the manufacturing process adopted. By way of example, without limitation, when it comes to packaging a sandwich 7 (FIG. 2) formed from two round half-breads of the kind of those produced in fast food restaurants, of substantially cylindrical shape. revolution, the coated folds 1 of the pleated packaging are deployed one by one, in their central part 8 following the cylindrical face 9 of the sandwich 7, from a retaining zone situated at the level of an area without coated folds 5 up to to the other zone without coated folds 6. During the deployment of coated folds 1, the edges of the pleated packaging where the ends 2 of the coated folds 1 are fixed together, fold over the lower 11 and upper 10 of the sandwich 7.
Le plissage de ces emballages plissés a lieu à partir d'une première bobine 12 (fig.3) de film primaire souple dont la largeur 13 est sensiblement celle qui sépare les extrémités 2 des plis couchés 1 le long desquels les plis couchés 1 sont fixés entre eux. Les plis couchés 1 sont réalisés perpendiculairement au sens de défilement de la bobine 12 en alternant une zone plissée 14 avec une zone sans plis 15. Puis les extrémités 2 des plis couchés 1 sont fixées entre elles au niveau du bord de la première bobine. Enfin, dans une première version, les emballages plissés sont séparés les uns des autres par une coupe transversale 16 au niveau des zones sans plis couchés 15 où il n'y a qu'une épaisseur de film primaire souple.The pleating of these pleated packaging takes place from a first reel 12 (fig. 3) of flexible primary film whose width 13 is substantially that which separates the ends 2 of the coated plies 1 along which the coated plies 1 are fixed between them. The coated plies 1 are produced perpendicular to the direction of travel of the reel 12 by alternating a pleated area 14 with an area without folds 15. Then the ends 2 of the coated pleats 1 are fixed together at the edge of the first reel. Finally, in a first version, the pleated packages are separated from each other by a cross section 16 at the level of the areas without coated folds 15 where there is only one thickness of flexible primary film.
Selon l'invention, on fixe une bande souple 17 (fig.l) dans la partie centrale 8 de l'emballage plissé et dans la direction perpendiculaire aux plis couchés 1 . Cette bande souple est d'une largeur 18 de l'ordre de dix à vingt pour cent de la distance entre les extrémités 2 de fixation des plis couchés 1. Cette bande souple est fixée sur la partie apparente de chaque pli couché 1 appelée le plat 3 au moyen d'un produit adhésif ou d'une colle pelable qui permet de l'enlever sans dégrader le film souple constituant l'emballage plissé. Ce moyen de fixation doit être suffisamment résistant pour permettre le déploiement des plis couchés sans qu'elle se détache du plat 3. De préférence, cette bande souple 17 n'est pas fixée, au film souple, à ses extrémités 19 et 20 situées au droit des zones sans plis couchés 5 et 6, pour permettre de saisir d'une main une des extrémités 19 ou 20 de la bande souple 17 tout en gardant une place suffisante pour tenir la zone sans plis couchés 5 ou 6 de l'emballage plissé correspondant à cette extrémité 19 ou 20 de l'autre main.According to the invention, a flexible strip 17 (fig.l) is fixed in the central part 8 of the pleated packaging and in the direction perpendicular to the coated plies 1. This flexible strip is of a width 18 of the order of ten to twenty for cent of the distance between the 2 fixing ends of the coated plies 1. This flexible strip is fixed on the visible part of each coated ply 1 called the flat 3 by means of an adhesive product or a peelable glue which allows the 'remove without degrading the flexible film constituting the pleated packaging. This fixing means must be strong enough to allow the deployment of the folded plies without it detaching from the dish 3. Preferably, this flexible strip 17 is not fixed, to the flexible film, at its ends 19 and 20 located at the right of the areas without coated folds 5 and 6, to allow one hand to grasp one of the ends 19 or 20 of the flexible strip 17 while keeping sufficient space to hold the area without coated folds 5 or 6 of the pleated packaging corresponding to this end 19 or 20 with the other hand.
Par exemple, pour déployer l'emballage plissé, on tire d'une main sur l'extrémité 19 (fig.l et 2) de la bande souple 17 dans la direction opposée à la zone sans plis 5 correspondante de l'emballage plissé qui est retenue par l'autre main. En tirant sur l'extrémité 19 de la bande souple 17, on tire sur un premier plat 21 d'un pli couché auquel correspond un creux 22, sur lequel la bande souple 17 est initialement fixée, pour déployer ledit creux 22 jusqu'à ce que le film souple soit tendu entre le plat 21 et la zone sans plis couchés 5 qui est retenue par l'autre main. Ainsi, on a déployé le premier pli couché, constitué du plat 21 et du creux 22, situé au voisinage de la zone sans plis couchés 5. Lorsque l'on continue à tirer sur la bande souple 17, l'effort résistant est suffisant, puisque le film souple est tendu, pour la décoller du premier plat 21. Le point de résistance suivant est le deuxième plat 23 qui reste fixé à la bande souple 17 jusqu'à ce que le creux 24 qui le sépare du premier plat 21 soit déployé. Lorsque le film souple est à nouveau tendu, le deuxième plat 23 se détache de la bande souple 17 et, ainsi, on déploie un par un les plis couchés successifs jusqu'à l'extrémité 20 de la bande souple 17 qui se détache alors complètement de l'emballage plissé déployé au droit de la zone sans plis couchés 6 opposée. Un moyen de mettre en place la bande souple 17 consiste à dérouler un film secondaire souple 26 de la largeur de la bande souple 17 à partir d'une deuxième bobine 25 (fig. 3) en cours de fabrication des emballages plissés dans la partie médiane du film primaire souple provenant de la première bobine 12, après plissage alternant les zones plissées 14 avec des zones sans plis 15 et fixation des plis couchés 1 à leurs extrémités 2 et avant séparation des emballages plissés par coupe transversale 16. Ce film secondaire 26 est d 'abord déroulé puis enduit sur toute ou partie de sa largeur, par exemple, d'une colle pelable suivant des aires enduites de colle pelable 27 de longueur correspondant à la longueur des zones plissées 14, dont la position est synchronisée avec le défilement des zones plissées 14 sur la machine. Cette colle est placée, à l'aide de buses 28, du côté convenable pour qu'elle vienne en contact avec les plats des plis couchés 1, lorsque le film secondaire souple 26 est appliqué et pressé dessus et s'y fixe provisoirement. Les aires sans colle pelable 29 qui viennent en contact avec les zones sans plis couchés 15 ne se collent pas du fait qu'elles ne comportent pas de colle pelable. Ensuite, lorsque l'on procède à la séparation des zones de plis couchés 14 par une découpe transversale 16 dans les zones sans plis couchés 15, on coupe la bande 17 dans une zone où elle n'est pas collée sur l'emballage plissé ce qui laisse une prise à chaque extrémité 19 et 20 pour saisir la bande lorsque l'on veut défaire les plis. For example, to deploy the pleated packaging, the end 19 (fig.l and 2) of the flexible strip 17 is pulled with one hand in the direction opposite to the corresponding pleated packaging-free area 5 which is held by the other hand. By pulling on the end 19 of the flexible strip 17, a first ply 21 is pulled from a lying ply to which corresponds a recess 22, on which the flexible strip 17 is initially fixed, to deploy said recess 22 until that the flexible film is stretched between the plate 21 and the area without coated folds 5 which is retained by the other hand. Thus, the first coated ply, consisting of the flat 21 and the hollow 22, located in the vicinity of the zone without coated plies 5, has been deployed. When the flexible strip 17 is continued to pull, the resistant force is sufficient, since the flexible film is stretched, in order to detach it from the first plate 21. The next point of resistance is the second plate 23 which remains fixed to the flexible strip 17 until the hollow 24 which separates it from the first plate 21 is deployed . When the flexible film is stretched again, the second plate 23 detaches from the flexible strip 17 and, in this way, the successive coated folds are deployed one by one up to the end 20 of the flexible strip 17 which then detaches completely of the pleated packaging deployed to the right of the zone without ply layers 6 opposite. One way to set up the flexible strip 17 consists in unwinding a flexible secondary film 26 the width of the flexible strip 17 from a second reel 25 (fig. 3) during the manufacture of pleated packages in the middle part of the flexible primary film coming from the first reel 12, after pleating alternating the pleated areas 14 with areas without pleats 15 and fixing of the folds 1 at their ends 2 and before separation of the pleated packages by cross section 16. This secondary film 26 is first unrolled and then coated over all or part of its width, for example, with a peelable adhesive according to areas coated with peelable adhesive 27 of length corresponding to the length of the pleated areas 14, the position of which is synchronized with the movement of the pleated areas 14 on the machine. This adhesive is placed, using nozzles 28, on the suitable side so that it comes into contact with the dishes of the coated plies 1, when the flexible secondary film 26 is applied and pressed thereon and temporarily fixed therein. The areas without peelable glue 29 which come into contact with the areas without coated folds 15 do not stick together because they do not include peelable glue. Then, when we proceed to the separation of the coated pleat zones 14 by a transverse cut 16 in the zones without coated pleats 15, the strip 17 is cut in an area where it is not glued on the pleated packaging. which leaves a grip at each end 19 and 20 to grip the strip when you want to undo the folds.
