Dispositif de renforcement d'un emballage plissé pour corps convexes.Reinforcement device for pleated packaging for convex bodies.
La présente invention vise un dispositif de renforcement d'un emballage pour corps convexes, réalisé à partir d'une feuille mince plissée dont les plis sont fixés à leurs extrémités pour lui donner une tenue à la charge verticale.The present invention relates to a device for reinforcing a package for convex bodies, produced from a thin pleated sheet whose folds are fixed at their ends to give it resistance to vertical load.
On connait par les brevets FR-A-2595666 et FR-A2628719 un emballage pour corps convexes réalisé à partir d'une feuille mince et souple qui permet dans l'une de ses applications de consommer un sandwich rond en laissant l'emballage autour du sandwich pour recueillir les coulures éventuelles et de le replier au fur et à mesure de la consommation du sandwich. La souplesse de la feuille permet de déployer manuellement les plis autour du corps convexe; en effet, pendant le déploiement des plis avec une main, on maintient avec l'autre main le corps convexe en le serrant entre les doigts; plus le film est souple moins on a besoin de serrer le corps convexe pour le maintenir entre les doigts; lorsque ce corps convexe est fragile comme, par exemple, les sandwiches de forme sensiblement cylindrique de révolution, produits en restauration rapide, réalisés à partir de pain brioché, on risque d'écraser le sandwich lors du déploiement de l'emballage plissé; la contrepartie de la souplesse de la feuille employée est que l'emballage ne protège pas le sandwich contre l'écrasement en cours de transport. D'où l'idée de protéger le sandwich, lorsqu'il est de forme cylindrique par un anneau de carton qui l'entoure sur toute sa paroi latérale, le tout étant ensuite entouré d'une feuille de papier mince. L'inconvénient d'un tel dispositif est que sa mise en oeuvre prend beaucoup de temps et que, lorsqu'il est associé à l'emballage plissé comme décrit dans le brevet FR-A-2676037, il est difficile d'enlever l'anneau de carton sans enlever l'emballage plissé qui, de ce fait, ne remplit plus son office de protection contre les coulures. Dans le cadre du développement de l'emballage plissé, on a essayé deWe know from patents FR-A-2595666 and FR-A2628719 a packaging for convex bodies made from a thin and flexible sheet which allows in one of its applications to consume a round sandwich leaving the packaging around the sandwich to collect any drips and fold it up as you eat the sandwich. The flexibility of the sheet makes it possible to manually deploy the folds around the convex body; in fact, during the deployment of the folds with one hand, the convex body is held with the other hand by squeezing it between the fingers; the more flexible the film the less need to tighten the convex body to hold it between the fingers; when this convex body is fragile such as, for example, sandwiches of substantially cylindrical shape of revolution, produced in fast food, made from brioche bread, there is a risk of crushing the sandwich when the pleated packaging is deployed; the counterpart of the flexibility of the sheet used is that the packaging does not protect the sandwich against crushing during transport. Hence the idea of protecting the sandwich, when it is cylindrical in shape by a cardboard ring which surrounds it over its entire side wall, the whole then being surrounded by a sheet of thin paper. The disadvantage of such a device is that its implementation takes a long time and that, when combined with the pleated packaging as described in patent FR-A-2676037, it is difficult to remove the cardboard ring without removing the pleated packaging which, as a result, no longer fulfills its function of protection against drips. As part of the development of pleated packaging, we tried to
FEUILLEDEREMPLACEMENT(REGLE261 - - fixer la bande de renfort directement sur la feuille mince dans la direction perpendiculaire aux plis; mais on est vite limité en épaisseur de renfort parce qu'il devient vite impossible de déployer le renfort sans écraser le sandwich. On a essayé ensuite, pour contourner cette difficulté, dans le brevet FR-A-2734791 , tout en gardant une bande de renfort fixée à la feuille, de la laisser prédéployée avec des plis égaux tandis que la partie plissée de l'emballage est plissée comme précédemment décrit; le problème est que, lorsqu'il est associé à une feuille plate, comme dans le brevet FR-A2676037, permettant de protéger les ouvertures supérieures et inférieures laissées par les bords de la partie plissée, il n'est plus possible de les empiler convenablement pour en réduire le volume occupé lors du transport de l'emballage plissé.LOCATION SHEET (RULE 261 - - fix the reinforcement strip directly on the thin sheet in the direction perpendicular to the folds; but we are quickly limited in thickness of reinforcement because it quickly becomes impossible to deploy the reinforcement without crushing the sandwich. We then tried, to get around this difficulty, in patent FR-A-2734791, while keeping a reinforcement strip fixed to the sheet, to leave it pre-deployed with equal folds while the pleated part of the packaging is pleated. as previously described; the problem is that, when combined with a flat sheet, as in patent FR-A2676037, making it possible to protect the upper and lower openings left by the edges of the pleated part, it is no longer possible to stack them properly to reduce the volume occupied during transport of the pleated packaging.
L'objet de l'invention est de réaliser un dispositif permettant d'obtenir un emballage plissé ayant une bonne résistance à la charge verticale, facile à déployer et facile à stocker lorsqu'il est replié pour le transport. Dans ce but, on associe aux plages successives séparées par un pli des renforts rectangulaires issus d'une bande de matériau semi-rigide, découpés, posés et fixés par des moyens appropriés.The object of the invention is to provide a device making it possible to obtain a pleated package having good resistance to vertical load, easy to deploy and easy to store when it is folded up for transport. To this end, rectangular reinforcements from a strip of semi-rigid material, cut, laid and fixed by appropriate means, are associated with successive ranges separated by a fold.
L'invention concerne aussi des dispositifs de pose, de pliage et de fixation des moyens de renforcement de 1'emballage.The invention also relates to devices for placing, folding and fixing the means for reinforcing the packaging.

Le dispositif consiste à associer à la feuille soupleThe device consists in associating with the flexible sheet
1 (fig.l) non plus une bande continue de renfort, mais une bande discontinue formée de renforts rectangulaires1 (fig.l) no longer a continuous strip of reinforcement, but a discontinuous strip formed of rectangular reinforcements
2 placés au voisinage les uns des autres et articulés entre eux par une charnière 3 formée de la feuille mince 1 qui les relie les uns aux autres. Le plissage étant formé de plages rectangulaires 5 et 6 successives séparées entre elles par des plis 4 faisant partie intégrante de la charnière 3 , les renforts rectangulaires 2 sont placés à l'intérieur de ces plages rectangulaires 5 et 6 et se replient les uns sur les autres de la même manière que les plis 4 de la feuille mince. Lorsqu'on replie les renforts rectangulaires 7 et 8 (fig.2) successifs l'un sur l'autre de manière que ces deux renforts rectangulaires 7 et 8 successifs soient en contact direct, il faut que la distance 9 qui les sépare soit supérieure ou égale à leur épaisseur 10 et 11 cumulée sinon la portion de feuille mince servant de charnière 12 subit une contrainte de tension qui peut soit empêcher le positionnement des renforts rectangulaires 7 et 8 l'un sur l'autre, soit provoquer un étirement de la partie de feuille mince formant charnière 12, soit sa déchirure; en contrepartie, lorsque le pli 13 est fait de telle sorte que ce soit la feuille mince 14 qui est en contact avec ellememe et que les renforts rectangulaires 8 et 15 se trouvent placés du côté extérieur, ils peuvent être positionnés l'un contre l'autre.2 placed in the vicinity of each other and hinged together by a hinge 3 formed from the thin sheet 1 which connects them to each other. The pleating being formed of successive rectangular areas 5 and 6 separated from each other by folds 4 forming an integral part of the hinge 3, the rectangular reinforcements 2 are placed inside these rectangular areas 5 and 6 and fold over each other. others in the same way as the folds 4 of the thin sheet. When folding the successive rectangular reinforcements 7 and 8 (fig. 2) one on the other so that these two successive rectangular reinforcements 7 and 8 are in direct contact, the distance 9 between them must be greater or equal to their combined thickness 10 and 11 otherwise the portion of thin sheet serving as a hinge 12 undergoes a tension stress which can either prevent the positioning of the rectangular reinforcements 7 and 8 one on the other, or cause a stretching of the part of thin sheet forming hinge 12, ie its tear; in return, when the fold 13 is made so that it is the thin sheet 14 which is in contact with itself and that the rectangular reinforcements 8 and 15 are placed on the outside, they can be positioned one against the other.
Le positionnement des renforts rectangulaires 2 (fig.l) les uns par rapport aux autres est l'une des principales difficultés résolues par le dispositif, objet de la présente invention, permettant de positionner correctement les renforts rectangulaires 2 les uns par rapport aux autres. Ces renforts rectangulaires 2 (fig.3) ont une hauteur 16 en cohérence avec la hauteur du corps convexe à protéger et plus particulièrement, à titre d'exemple non limitatif, du sandwich de forme sensiblement cylindrique de révolution, précédemment décrit; lorsque l'emballage ainsi réalisé est déployé (fig.3), la succession des renforts rectangulaires 2 reliés entre eux par les charnières 17 de la feuille souple 1 constitue une suite de dièdres formant sensiblement un anneau 18; lorsqu'on applique des charges verticales sur cet anneau 18 placé sur un plan horizontal, le flambage des renforts rectangulaires 2 sous la charge est limité par la mise sous contrainte de tension orientée horizontalement de la feuille mince formant charnière 17; la résistance de cet anneau 18 est limitée, entre autres causes, par la résistance de la feuille mince 1 qui finit par se déchirer sous l'action de la tension lorsque la charge devient trop importante; le renfort rectangulaire 2 peut alors fléchir. Une manière d'envisager la pose des rectangles de renfort 2 (fig.4), consiste à partir d'une bobine de matériau semi-rigide dont la largeur correspond à la hauteur 16 (fig.3) du renfort rectangulaire; cette bande 19 (fig.4) est tirée par des rouleaux 20 à une vitesse légèrement inférieure à la vitesse de défilement de la bande de feuille mince 21 sur laquelle elle va être fixée. La bande 19 de matériau semi-rigide est ensuite entraînée par un cylindre support 22 tournant avec une vitesse tangentielle égale à la vitesse de défilement de la bande de feuille mince 21; la bande 19 de matériau semi-rigide est maintenue sur le cylindre support 22 par un système 23 de trous ou de fentes 24 d'aspiration qui lui permettent de glisser légèrement compte tenu de la différence de vitesse de défilement entre la vitesse tangentielle du cylindre support 22 et celle de la bande 19. Le cylindre support 22 sert d'enclume à des couteaux 25, solidaires d'un cylindre de coupe 26,- dont le fil 27 vient tangenter le cylindre support 22 suivant ses génératrices. La position des couteaux 25 sur le cylindre de coupe 26 et sa vitesse sont déterminés pour découper des renforts rectangulaires 2 dont la largeur est telle qu'il s'adaptent alternativement à la largeur de chacune des plages de feuille mince 5 et 6 (fig.l) séparant deux plis 4 successifs de l'emballage lorsqu'il est plié.The positioning of the rectangular reinforcements 2 (fig.l) relative to each other is one of the main difficulties solved by the device, object of the present invention, making it possible to correctly position the rectangular reinforcements 2 by compared to others. These rectangular reinforcements 2 (fig.3) have a height 16 in coherence with the height of the convex body to be protected and more particularly, by way of nonlimiting example, of the sandwich of substantially cylindrical shape of revolution, previously described; when the packaging thus produced is deployed (fig. 3), the succession of rectangular reinforcements 2 connected together by the hinges 17 of the flexible sheet 1 constitutes a series of dihedrons substantially forming a ring 18; when vertical loads are applied to this ring 18 placed on a horizontal plane, the buckling of the rectangular reinforcements 2 under the load is limited by the horizontally oriented tensioning stress of the thin sheet forming a hinge 17; the resistance of this ring 18 is limited, among other causes, by the resistance of the thin sheet 1 which ends up tearing under the action of tension when the load becomes too great; the rectangular reinforcement 2 can then flex. One way of considering the installation of the reinforcement rectangles 2 (fig. 4), consists of starting from a coil of semi-rigid material whose width corresponds to the height 16 (fig. 3) of the rectangular reinforcement; this strip 19 (fig.4) is pulled by rollers 20 at a speed slightly lower than the running speed of the strip of thin sheet 21 on which it will be fixed. The strip 19 of semi-rigid material is then driven by a support cylinder 22 rotating with a tangential speed equal to the running speed of the thin sheet strip 21; the strip 19 of semi-rigid material is held on the support cylinder 22 by a system 23 of holes or suction slots 24 which allow it to slide slightly taking into account the difference in running speed between the tangential speed of the support cylinder 22 and that of the strip 19. The support cylinder 22 serves as anvil for knives 25, integral with a cutting cylinder 26, - the wire 27 of which tangents the support cylinder 22 along its generatrices. The position of the knives 25 on the cutting cylinder 26 and its speed are determined to cut rectangular reinforcements 2 whose width is such that they alternately adapt to the width of each of the thin sheet areas 5 and 6 (fig.l) separating two successive folds 4 of the package when it is folded .
Généralement la vitesse tangentielle du fil 27 (fig.4) des couteaux 25 est égale à/ou voisine de la vitesse tangentielle du cylindre support 22 suivant le degré d'usure des couteaux 25; en tout état de cause les points de contact du fil 27 des couteaux 25 sur la surface du cylindre support 22 se fait toujours aux mêmes places, les trous ou fentes 24 d'aspiration servant au maintien des renforts rectangulaires 2 étant situés entre ces points de contact. Compte tenu de la différence de vitesse entre la bande 19 et la surface du cylindre de support 22, dès que le renfort rectangulaire 28 est découpé, il est entraîné à la vitesse du cylindre support 22 et il se créé ainsi un espace entre deux renforts rectangulaires 28 et 29 successifs. On peut amener alors la bande formée d'une feuille mince 21 à tangenter le cylindre support 22 dans la zone comportant les renforts rectangulaires 30 qui viennent s'appliquer avec précision sur la feuille mince 21 et s'y fixer suivant un moyen connu; ensuite, on coupe l'aspiration sur les trous ou fentes 24 du cylindre de support 22 qui maintenaient les renforts rectangulaires 31 en place et l'on dégage une feuille mince munie de renforts rectangulaires comme représenté par la figure 1. On peut alors procéder au plissage.Generally the tangential speed of the wire 27 (fig.4) of the knives 25 is equal to or close to the tangential speed of the support cylinder 22 depending on the degree of wear of the knives 25; in any event, the contact points of the wire 27 of the knives 25 on the surface of the support cylinder 22 are always made in the same places, the suction holes or slots 24 serving to maintain the rectangular reinforcements 2 being situated between these points contact. Given the difference in speed between the strip 19 and the surface of the support cylinder 22, as soon as the rectangular reinforcement 28 is cut, it is driven at the speed of the support cylinder 22 and a space is thus created between two rectangular reinforcements 28 and 29 successive. It is then possible to bring the strip formed from a thin sheet 21 to tangent the support cylinder 22 in the zone comprising the rectangular reinforcements 30 which are applied with precision to the thin sheet 21 and to be fixed thereon by known means; then, the suction is cut on the holes or slots 24 of the support cylinder 22 which held the rectangular reinforcements 31 in place and a thin sheet provided with rectangular reinforcements is released as shown in FIG. 1. We can then proceed to the pleating.
Dans une version préférée de l'invention, le plissage se fait suivant un procédé dérivant directement du brevet européen 0 528 920; les plages 5 et 6 situées de part et d'autre d'un pli 4 sont de largeur A 32 et B 33 avec A>B; les plages ont alternativement une largeur A 32 et une largeur B 33; la plage 34 (fig.2) de largeur A 32 est décomposée en une plage 35 de largeur A-B 36 et une plage 37 de largeur B 38; ces deux plages 34 et 35 sont séparées par un pli 39; les deux plages 37 et 41 de largeur B 38 et 33 étant placées côte à côte; le renfort rectangulaire 40 comporte une découpe au droit de ce pli 39; la découpe du renfort rectangulaire 40 (fig.4) de largeur A est réalisée sur le cylindre support 22 par un deuxième cylindre de coupe 42; le renfort rectangulaire 40 étant déjà séparé de la bande 19 par la découpe par le cylindre de coupe 25, les deux morceaux 44 et 45 obtenus par la découpe 43 restent sensiblement côte à côte; cela ne pose pas de problème dans la mesure où la partie 44 de largeur A-B se trouve en tête du renfort rectangulaire 40 de la plage de largeur A pris dans le sens du déplacement; la découpe au droit du pli 39 peut aussi être réalisée par des couteaux placés sur le cylindre de coupe 26; il y a dans ces conditions un espace créé entre les deux parties du renfort. La feuille 46 munie de ses renforts rectangulaires 2 passe sur une roue de préformage 47 (fig.5) comportant des dents 48, les renforts rectangulaires 49 étant situés du côté de la roue 47; la plage 50 de largeur A-B se place au fond de la dent 47, les deux plages 51 et 52 de largeur B recouvrent la dent 47 qui est en forme de V renversé. Une roue de resserrement des plis 53 composée de barreaux 54 vient prendre la feuille mince préformée avec ses renforts rectangulaires; les plages 55 de la largeur A- B se placent au sommet des barreaux 54 tandis que les deux plages 56 et 57 de largeur B se placent dans le creux formé par deux barreaux 54 et 58 successifs; les renforts rectangulaires sont alors du côté extérieur de la roue de resserrement des plis 53; lorsque les barreaux 54 se rapprochent les plages 59 et 60 de largeur B se rapprochent et les renforts rectangulaires se superposent sans problème du fait de l'espace 12 (fig.2) laissé entre deux renforts rectangulaires 7 et 8 successifs au moment de la découpe et les plages 61 et 62 de largeur A-B se placent côte à côte; il est cependant nécessaire que les plages de largeur B aient suffisamment de jeux lorsque les barreaux 63 et 64 sont rapprochés pour qu'elles puissent se dégager facilement du fait de leur rigidité. Ensuite les plages 61 et 62 'de largeur A-B sont transférées sur le cylindre de regroupement des plis 65 avec le renfort rectangulaire tourné vers ce dernier 65 et, les plages 66 et 67 de largeur B successives formant une excroissance, les renforts rectangulaires correspondants étant situés à l'intérieur de l'excroissance; ensuite on procède au couchage des plis à l'aide d'un cylindre comprenant, à hauteur des renforts rectangulaires, un diamètre réduit tenant compte des diverses épaisseurs de renfort rectangulaire qui viennent se superposer et qui font une surépaisseur significative.In a preferred version of the invention, the pleating is done according to a process deriving directly from European patent 0 528 920; areas 5 and 6 located on either side of a fold 4 are of width A 32 and B 33 with A>B; the pads have alternately a width A 32 and a width B 33; the range 34 (fig.2) of width A 32 is broken down into a range 35 of width AB 36 and a range 37 of width B 38; these two areas 34 and 35 are separated by a fold 39; the two tracks 37 and 41 of width B 38 and 33 being placed side by side; the rectangular reinforcement 40 has a cut to the right of this fold 39; the cut rectangular reinforcement 40 (fig.4) of width A is produced on the support cylinder 22 by a second cutting cylinder 42; the rectangular reinforcement 40 already being separated from the strip 19 by the cut by the cutting cylinder 25, the two pieces 44 and 45 obtained by the cut 43 remain substantially side by side; this does not pose a problem insofar as the portion 44 of width AB is at the head of the rectangular reinforcement 40 of the range of width A taken in the direction of movement; the cut to the right of the fold 39 can also be carried out by knives placed on the cutting cylinder 26; in these conditions there is a space created between the two parts of the reinforcement. The sheet 46 provided with its rectangular reinforcements 2 passes over a preforming wheel 47 (fig.5) having teeth 48, the rectangular reinforcements 49 being located on the side of the wheel 47; the area 50 of width AB is placed at the bottom of the tooth 47, the two areas 51 and 52 of width B cover the tooth 47 which is in the form of an inverted V. A fold tightening wheel 53 made up of bars 54 takes the preformed thin sheet with its rectangular reinforcements; the pads 55 of width A- B are placed at the top of the bars 54 while the two pads 56 and 57 of width B are placed in the hollow formed by two successive bars 54 and 58; the rectangular reinforcements are then on the outside of the fold tightening wheel 53; when the bars 54 approach the ranges 59 and 60 of width B approach and the rectangular reinforcements are superimposed without problem because of the space 12 (fig.2) left between two successive rectangular reinforcements 7 and 8 at the time of cutting and the tracks 61 and 62 of width AB are placed side by side; it is however necessary that the pads of width B have sufficient play when the bars 63 and 64 are brought together so that they can be released easily due to their rigidity. Then the areas 61 and 62 ′ of width AB are transferred to the ply grouping cylinder 65 with the rectangular reinforcement facing the latter 65 and, the successive areas 66 and 67 of width B forming a protrusion, the reinforcements corresponding rectangles being located inside the protrusion; then the plies are coated using a cylinder comprising, at the height of the rectangular reinforcements, a reduced diameter taking into account the various thicknesses of rectangular reinforcement which come to be superimposed and which make a significant extra thickness.
Une manière de fixer les renforts rectangulaires sur la feuille mince, consiste à utiliser un renfort rectangulaire enduit d'une mince couche de matière thermosoudable placée du côté extérieur 70 par rapport au cylindre support 22; la feuille mince peut aussi être enduite d'une mince couche de matière thermosoudable du côté 69 faisant face au renfort rectangulaire; la fixation du renfort se fait alors au moment de l'application de la feuille souple sur le renfort rectangulaire par chauffage à l'air chaud 68 de la face de la feuille souple opposée à celle qui est enduite. One way to fix the rectangular reinforcements on the thin sheet, consists in using a rectangular reinforcement coated with a thin layer of heat-sealable material placed on the outer side 70 relative to the support cylinder 22; the thin sheet can also be coated with a thin layer of heat-sealable material on the side 69 facing the rectangular reinforcement; fixing the reinforcement is then made at the time of application of the flexible sheet on the rectangular reinforcement by heating with hot air 68 of the face of the flexible sheet opposite to that which is coated.
