Description

L'invention concerne un procédé et un dispositif pour la réalisation et la mise en place d'un intercalaire de séparation de type à cloison mince interposé entre les objets d'un groupe d'objets juxtaposés à emballer ainsi qu' un procédé d'emballage utilisant un tel intercalaire.The invention relates to a method and a device for the production and installation of a separation divider of the thin partition type interposed between the objects of a group of juxtaposed objects to be packaged as well as a packaging process. using such a spacer.

L'invention s'applique plus spécialement au cas où les objets sont des bouteilles ou similaires.The invention applies more particularly to the case where the objects are bottles or the like.

On connaît déjà de nombreuses formes de réalisation d'intercalaires ( documents FR 2.465.653, 2.475.002, 2.499.948, 2.501.160, 2.503.034, 2.523.548, 2.447.866, 2.421.116, 2.360.473, 2.389.546, 2.431.959, 2.481.243, 2.541.235). Le plus souvent ces intercalaires en carton sont constitués de plusieurs éléments plans associés entre eux, ce qui a comme inconvénients de nécessiter une quantité importante de carton , des opérations complexes de collage, découpage, association, pliage, d'être finalement inesthétiques.Numerous embodiments of dividers are already known (documents FR 2,465,653, 2,475,002, 2,499,948, 2,501,160, 2,503,034, 2,523,548, 2,447,866, 2,421,116, 2,360,473, 2,389,546, 2,431,959, 2,481,243, 2,541,235). Most often these cardboard dividers consist of several planar elements associated with each other, which has the disadvantages of requiring a large amount of cardboard, complex operations of bonding, cutting, association, folding, to be ultimately unsightly.

On connaît aussi (document FR 2.310.270) un procédé et un dispositif pour la réalisation et la mise en place d'un intercalaire en vue de l'emballage de bouteille, dans lesquels une bande de matière -destinée à former l'intercalaire- est conduite en méandres, en ligne doublement ondulée jusqu'à présenter le contour finalement souhaité. Puis la bande ainsi conformée est enfilée sur les bouteilles à emballer. Toutefois, ce procédé et ce dispositif ont comme inconvénients que la déformation de la bande, progressivement, dans sa direction longitudinale, lors de son avancement, est complexe.There is also known (document FR 2,310,270) a method and a device for producing and installing an interlayer for the packaging of the bottle, in which a strip of material - intended to form the interlayer - is conducted in meanders, in a doubly wavy line until presenting the finally desired contour. The strip thus shaped is then threaded onto the bottles to be packaged. However, this method and this device have the disadvantages that the deformation of the strip, gradually, in its longitudinal direction, during its advancement, is complex.

L'invention a donc pour objectif un procédé et un dispositif pour la réalisation d'un intercalaire qui simultanément utilisent le minimum de matière constitutive, soient d'une réalisation et d'une mise en place particulièrement simple ; soit fiable.The object of the invention is therefore to provide a method and a device for the production of an interlayer which simultaneously uses the minimum of constituent material, is of a particularly simple production and installation; be reliable.

L'invention concerne ensuite un procédé d'emballage d'un groupe d'objets juxtaposés avec intercalaire de séparation du type à cloison mince, caractérisé par le fait que l'on réalise et on met en place sur le groupe au moins un intercalaire par le procédé ; et après on place les objets avec le ou les intercalaires placés autour dans un contenant enveloppant le groupe.The invention then relates to a method of packaging a group of juxtaposed objects with a separation divider of the thin wall type, characterized in that at least one spacer is produced and placed on the group. the process; and then the objects are placed with the interlayer (s) placed around in a container enveloping the group.

Pour former l'intercalaire 1 on part d'abord d'un tronçon 7 de bande essentiellement déformable longitudinalement . Puis on le déforme progressivement jusqu'à ce qu'il présente une forme de surface réglée parallèlement à une direction transversale T et à partir d'une courbe de référence 8 , le tronçon de bande ainsi conformé formant alors l'intercalaire 1 interposé entre les objets 3. A cet effet, on garde le tronçon 7 au moins sensiblement stationnaire, dans son ensemble, et on procède alors à sa déformation transversale ( et éventuellement longitudinale), jusqu'à l'amener progressivement jusqu'à la forme de surface réglé par rapport à la courbe de référence 8. On entend par maintien au moins sensiblement stationnaire du tronçon 7, pendant sa déformation transversale, le fait que le tronçon 7 n'a pas besoin d'être déplacé, dans son ensemble, longitudinalement et/ou transversalement en vue de réaliser la déformation transversale (contrairement, par exemple, au document FR 2.310.270 où un tel déplacement longitudinal est indispensable pour réaliser la déformation). Toutefois, il est bien entendu qu'un tel déplacement peut intervenir, indépendamment et en plus de la déformation transversaleTo form the interlayer 1, one starts first with a section 7 of strip which is essentially deformable longitudinally. Then it is gradually deformed until it has a surface shape adjusted parallel to a transverse direction T and from a reference curve 8, the strip section thus shaped then forming the interlayer 1 interposed between the objects 3. To this end, the section 7 is kept at least substantially stationary, as a whole, and its transverse (and possibly longitudinal) deformation is then carried out, until it is brought gradually to the set surface shape. with respect to the reference curve 8. The term “maintaining at least substantially stationary of the section 7, during its transverse deformation, means that the section 7 does not need to be displaced, as a whole, longitudinally and / or transversely in order to carry out the transverse deformation (unlike, for example, in document FR 2,310,270 where such a longitudinal displacement is essential for carrying out the deformation). However, it is understood that such a displacement can occur, independently and in addition to the transverse deformation

Les objets 3 reposent sur des moyens support 9 lesquels sont de forme générale plane et placés horizontalement, les objets 3 s'étendant le long d'axes 10 dirigés verticalement ; la direction transversale T est alors verticale.The objects 3 rest on support means 9 which are of generally planar shape and placed horizontally, the objects 3 extending along axes 10 directed vertically; the transverse direction T is then vertical.

Les objets 3 sont groupés dans leur configuration définitive l'espace 2 existant originellement entre eux pour permettre la mise en place de l'intercalaire 1.The objects 3 are grouped in their final configuration the space 2 originally existing between them to allow the establishment of the interlayer 1.

Une configuration typique d'objets 3 est celle comprenant six objets 3 répartis en deux lignes et trois rangées. Toutefois, l'invention s'applique également à d'autres configurations notamment celle à trois lignes et quatre rangées, soit douze objets 3.A typical configuration of objects 3 is that comprising six objects 3 distributed in two lines and three rows. However, the invention also applies to other configurations, in particular that with three lines and four rows, ie twelve objects 3.

Un tronçon 7 de bande est une pièce qui, à plat, a une forme générale rectangulaire limitée notamment par deux petits bords transversaux 11 placés verticalement et deux grands bords longitudinaux 12 situés. dans des plans horizontaux, lorsque l'intercalaire 1 est mis en place est verticalement.A strip section 7 is a part which, flat, has a generally rectangular shape limited in particular by two small transverse edges 11 placed vertically and two large longitudinal edges 12 located. in horizontal planes, when insert 1 is in place is vertically.

Une déformation longitudinale du tronçon 7 de bande est telle que les deux bords longitudinaux 12 soient déformés de façon similaire, de même que toute ligne intermédiaire entre les deux bords longitudinaux 12; et que les deux bords transversaux 11 ne soient pas substantiellement déformés de même que toute ligne intermédiaire entre les deux bords transversaux 11. Le tronçon 7 de bande forme alors une nappe à une ou plusieurs ondulations plus ou moins prononcées. Le tronçon 7 de bande est déformable sur toute sa longueur de façon continue par le fait que, d'une part, la déformation peut intervenir sur toute zone transversale plus ou moins étendue longitudinalement située entre les deux bords transversaux 11 et que, d'autre part, la déformation est progressive et "élastique", c'est-à-dire, que le rayon de courbure du tronçon 7 de bande varie de façon continue. Le tronçon 7 de bande peut être courbé plus ou moins fortement sur un tronçon transversal d'une certaine longueur (plutôt que d'être plié le long d'une ligne localisée).A longitudinal deformation of the strip section 7 is such that the two longitudinal edges 12 are similarly deformed, as is any intermediate line between the two longitudinal edges 12; and that the two transverse edges 11 are not substantially deformed, as is any intermediate line between the two transverse edges 11. The strip section 7 then forms a sheet with one or more more or less pronounced undulations. The strip section 7 can be deformed continuously over its entire length by the fact that, on the one hand, the deformation can occur over any more or less longitudinally extended transverse zone situated between the two transverse edges 11 and that, on the other apart, the deformation is progressive and "elastic", that is to say, the radius of curvature of the strip section 7 varies continuously. The strip section 7 can be bent more or less strongly over a transverse section of a certain length (rather than being folded along a localized line).

La surface réglée que forme le tronçon 7 de bande est définie par un segment de direction transversale T, verticale et parallèle aux bords transversaux 11, déplacé le long de la courbe de référence 8. La courbe de référence 8 constitue, au moins approximativement, celle d'une section droite longitudinale de l'intercalaire 1 (correspondant aux bords longitudinaux 12) une fois mis en place sur les objets 3. A cet effet, la courbe de référence 8 a une forme plus ou moins complexe déterminée par la configuration du groupe 4 d'objets, de manière à être interposée entre les projections axiales des objets, sur les moyens support 7.The adjusted surface formed by the section 7 of the strip is defined by a segment of transverse direction T, vertical and parallel to the transverse edges 11, displaced along the reference curve 8. The reference curve 8 constitutes, at least approximately, that of a longitudinal cross section of the interlayer 1 (corresponding to the longitudinal edges 12) once placed on the objects 3. For this purpose, the reference curve 8 has a more or less complex shape determined by the configuration of the group 4 of objects, so as to be interposed between the axial projections of the objects, on the support means 7.

Par exemple dans le cas particulier d'une configuration à deux lignes et trois rangées d'objets 3, ainsi que représenté, la courbe de référence 8 commence et finit entre les deux lignes de la configuration. La courbe 8 forme initialement environ un quart de tour en sens positif autour de l'objet 3 situé en première ligne et première rangée ; puis après un point d'inflexion, forme environ trois quart de tour en sens négatif autour de l'objet 3 situé en première ligne et deuxième rangée puis après un point d'inflexion, forme environ trois quart de tour en sens positif autour de l'objet 3 situé en deuxième ligne et deuxième rangée ; puis après un point d'inflexion, forme environ un quart de tour en sens négatif autour de l'objet 3 situé en deuxième ligne et troisième rangée. Si on désigne l'objet de la ième ligne et jème rangée par Li Rj, la courbe 8 ci-dessus est définie par la séquence des références L1R1, L1R2, L12R2, L2R3. On appelle sens positif, les sens des aiguilles d'une montre et sens négatif, le sens opposé. Dans le cas d'une configuration à trois lignes et quatre rangées d'objets 3, la courbe 8 peut être définie par la séquence L1R1, L2R1, L3R1, L3R2, L2R2, L2R1, L1R3, L2R3, L3R3, L3R4, L2R4, L1R4. Dans les différentes configurations, la courbe 8 forme, selon les cas, au moins une partie et généralement une pluralité de partie de tour comprise entre environ un quart de tour et environ trois quart de tour.For example in the particular case of a configuration with two lines and three rows of objects 3, as shown, the reference curve 8 begins and ends between the two lines of the configuration. Curve 8 initially forms approximately a quarter turn in a positive direction around the object 3 located in the first line and first row; then after an inflection point, form approximately three quarter turns in a negative direction around the object 3 located in the first line and second row then after an inflection point, form approximately three quarter turns in a positive direction around the object 3 located in second line and second row; then after an inflection point, form a quarter turn in a negative direction around the object 3 located in second line and third row. If we designate the object of the ith line and jth row by Li Rj, the curve 8 above is defined by the sequence of references L1R1, L1R2, L12R2, L2R3. We call positive direction, clockwise and negative direction, opposite direction. In the case of a configuration with three lines and four rows of objects 3, the curve 8 can be defined by the sequence L1R1, L2R1, L3R1, L3R2, L2R2, L2R1, L1R3, L2R3, L3R3, L3R4, L2R4, L1R4 . In the various configurations, the curve 8 forms, as the case may be, at least one part and generally a plurality of part of the tower comprised between about a quarter of a turn and about three quarter of a turn.

Selon une première variante (non représentée) on conforme d'abord le tronçon 7 de bande autour de gabarits puis simultanément, on dissocie le tronçon 7 conforme des gabarits et on l'intercale avec la même conformation entre les objets 3 du groupe 4 au moins sensiblement dans leur position relative finale. On dispose les objets 3 et les gabarits, une fois le tronçon 7 de bande conformé, dans la même configuration et les uns en regard des autres, dans le sens transversal (vertical), et on effectue un coulissement relatif du tronçon 7 de bande conformé, dans les sens transversal, des gabarits au groupe 4 d'objets.According to a first variant (not shown), the section 7 of the strip is first conformed around templates, then simultaneously, the conforming section 7 is separated from the templates and inserted with the same conformation between the objects 3 of group 4 at least. substantially in their final relative position. The objects 3 and the templates are placed, once the section 7 of strip conformed, in the same configuration and facing each other, in the transverse (vertical) direction, and a relative sliding of the section 7 of strip conformed , in transverse directions, templates to group 4 of objects.

Selon une seconde variante possible préférentielle et représentée on conforme directement le tronçon 7 de bande par et entre les objets 3 et non par l'intermédiaire de gabarits et, à cet effet, on place d'abord le tronçon 7 de bande au moins sensiblement à plat entre les objets 3 dans une position initiale écartée où ils sont écartés transversalement horizontalement et longitudinalement les uns des autres tout en reposant sur les moyens supports 9 pour élargir horizontalement l'espace 2 (pour permettre cette mise en place) puis, on déplace relativement les objets 3 jusqu'à les amener dans leur configuration relative définitive plus rapprochée où l'espace 2 est plus petit horizontalement, ce mouvement relatif des objets 3 provoquant la déformation transversale concomitante du tronçon 7. Dans ce cas, la réalisation de l'intercalaire 1 et sa mise en place finale entre les objets 3 sont réalisées simultanément, les objets 3 constituant le moyen positif direct assurant la déformation du tronçon de bande 7. Et cette déformation résultant du mouvement relatif de rapprochement des objets 3, l'espace 2 étant diminué d'une valeur initiale importante à une valeur finale définitive, plus faible. Dans la première variante où on utilise des gabarits pour déformer transversalement le tronçon 7 de bande, cette déformation résulte d'un mouvement relatif des gabarits semblable au mouvement relatif des objets 3 prévu dans la seconde variante.According to a second preferred and shown alternative variant, the strip section 7 is conformed directly by and between the objects 3 and not by means of templates and, to this end, the strip section 7 is first placed at least substantially at flat between the objects 3 in an initial spread apart position where they are spread transversely horizontally and longitudinally of each other while resting on the support means 9 to horizontally widen the space 2 (to allow this positioning) then, the objects 3 are relatively displaced until they are brought into their final relative configuration closer together where the space 2 is smaller horizontally, this relative movement of the objects 3 causing the concomitant transverse deformation of the section 7. In this case, the production of the interlayer 1 and its final positioning between the objects 3 are carried out simultaneously, the objects 3 constituting the direct positive means ensuring the deformation of the strip section 7. And this deformation resulting from the relative movement of approximation of the objects 3, the space 2 being reduced from a large initial value to a final, lower final value. In the first variant where jigs are used to deform the strip section 7 transversely, this deformation results from a relative movement of the jigs similar to the relative movement of the objects 3 provided for in the second variant.

On part soit d'un tronçon 7 de bande à plat soit d'une bande continue enroulée en bobine qu'on coupe à la longueur souhaitée, pour former un tronçon 7.We start either from a flat strip 7 section or from a continuous strip wound in a reel which is cut to the desired length, to form a section 7.

L'invention concerne également un procédé d'emballage d'un groupe 4 d'objets dans lequel on dispose d'abord les objets 3 au moins approximativement dans la configuration de l'emballage final notamment dans la position écartée ; puis on réalise et on met en place sur le groupe 4 au moins un intercalaire 1 ainsi que décrit précédemment ; enfin on place après les objets 3 avec le ou les intercalaires 1 placés autour dans un contenant enveloppant le groupe 4, notamment, au moins partiellement, en carton. Le contenant peut faire l'objet de variantes : caisse américaine, barquette associée à un capuchon en matière plastique, emballage tout plastique ou autre.The invention also relates to a method of packaging a group 4 of objects in which the objects 3 are first placed at least approximately in the configuration of the final packaging, in particular in the separated position; then at least one interlayer 1 is produced and put in place on group 4 as described above; finally, the objects 3 are placed afterwards with the interlayer (s) 1 placed around in a container enveloping the group 4, in particular, at least partially, made of cardboard. The container can be subject to variants: American box, tray associated with a plastic cap, all-plastic packaging or other.

Avant d'être conformé et mis en place, l'intercalaire 1 se présente sous la forme d'une découpe de forme générale rectangulaire, en élévation. Le procédé selon l'invention vise à donner à l'intercalaire 1 une forme tridimensionnelle de surface réglée à partir de la courbe de référence 8, adaptée, à la configuration du groupe 4 d'objets 3. L'intercalaire 1 comporte un tronçon 7 de bande unique et la courbe de référence 8 peut former au moins un demi tour. Ou la courbe de référence 8 peut avoir au moins un trois quart de tour, et notamment deux trois quart de tour, de manière à séparer quatre objets 3.Before being shaped and put in place, the interlayer 1 is in the form of a generally rectangular cutout, in elevation. The method according to the invention aims to give the interlayer 1 a three-dimensional surface shape adjusted from the reference curve 8, adapted to the configuration of group 4 of objects 3. The interlayer 1 comprises a section 7 of single strip and the reference curve 8 can form at least half a turn. Or the reference curve 8 can have at least one three quarter turn, and in particular two three quarter turn, so as to separate four objects 3.

L'intercalaire 1 peut être réalisé en carton simple face ou encore en carton ondulé. Cette forme de réalisation présente l'avantage de faciliter la déformation longitudinale par "roulage" du tronçon 7 de bande tout en empêchant la déformation transversale. L'intercalaire 1 comporte alors, une fois mis en place, un caractère auto-portant grâce à la rigidité transversale qu'il présente.The interlayer 1 can be made of single-sided cardboard or also of corrugated cardboard. This embodiment has the advantage of facilitating the longitudinal deformation by "rolling" of the section 7 of the strip while preventing transverse deformation. The interlayer 1 then comprises, once in place, a self-supporting character thanks to the transverse rigidity which it presents.

L'invention concerne, enfin, un dispositif pour la réalisation et la mise en place d'un intercalaire 1 tel qu'il a été décrit, interposé entre les objets 3 du groupe 4 d'objets.Finally, the invention relates to a device for producing and installing an insert 1 as described, interposed between the objects 3 of the group 4 of objects.

Ce dispositif est tel que le tronçon 7 est déformé d'une part complètement, c'est-à-dire pour toute sa longueur (entre les bords transversaux 11) -et cela dès le début de la conformation- et, d'autre part, progressivement puisque le tronçon 7 dans sa totalité ne passe que progressivement de sa forme initiale à sa conformation définitive.This device is such that the section 7 is completely deformed on the one hand, that is to say for its entire length (between the transverse edges 11) - and this from the start of the conformation - and, on the other hand , gradually since the section 7 in its entirety passes only gradually from its initial shape to its final conformation.

Ce dispositif comporte des moyens d'alimentation 13 en tronçons 7 de bande ; des moyens de saisie et d'entraînement du tronçon 7 de la bande notamment dans la direcitn longitudinale et/ou transversale ; des moyens de déformation transversale du tronçon 7 de bande c'est-à-dire des moyens propres à amener le tronçon de bande 7 à présenter une forme de surface réglée parallèlement à une direction transversale et à partir d'une courbe de référence 8 ; et des moyens 9 support des objets 3. Les moyens d'alimentation en tronçons 7 de bande sont constitués, par exemple, par un magasin de découpes à plat superposées ou par un mandrin support d'une bobine de bande associée à des moyens de coupe transversale.This device comprises means 13 for supplying strip sections 7; means for gripping and driving the section 7 of the strip, in particular in the longitudinal and / or transverse direction; means for transverse deformation of the strip section 7, that is to say means suitable for causing the strip section 7 to have a surface shape adjusted parallel to a transverse direction and from a reference curve 8; and means 9 for supporting objects 3. The means for supplying strip sections 7 consist, for example, of a store of superimposed flat cutouts or by a support mandrel of a strip reel associated with cutting means. transverse.

De tels moyens d'alimentation sont connus ou à la portée de l'homme du métier dans le domaine technique de l'emballage et, pour cette raison, ne sont pas décrits davantage. Ces moyens d'alimentation peuvent faire l'objet de nombreuses variantes de réalisation telle qu'en sortie on ait des tronçons 7 de bande successifs non encore conformés et mis en place.Such supply means are known or within the reach of those skilled in the art in the technical field of packaging and, for this reason, are not described further. These supply means can be the subject of numerous alternative embodiments such that, at the output, there are successive strip sections 7 not yet shaped and put in place.

Les moyens de saisie et d'entraînement ont pour fonctions de saisir le tronçon de bande 7 des moyens d'alimentation et de le déplacer ainsi qu'il est souhaité notamment avant sa conformation pour le placer entre les gabarits ou les objets 3 assurant la déformation transversale. De tels moyens de saisie et d'entraînement sont constitués, par exemple, de pinces, de doigts, de ventouses, de chariot ou équivalent ou autres entraîné en déplacement au moyen de moteur, moto-réducteur, piston ou autres, directement ou par l'intermédiaire de chariot, chaîne sans fin, vis filetées etc ... De tels moyens de saisie et d'entraînement sont connus ou à la portée de l'homme du métier dans le domaine technique de l'emballage et, pour cette raison, ne sont pas décrits davantage,. Ces moyens de saisie et d'entraînement peuvent faire l'objet de nombreuses variantes de réalisation remplissant la fonction indiquée.The gripping and driving means have the function of gripping the strip section 7 of the feeding means and of displacing it as desired, in particular before it is shaped to place it between the templates or the objects 3 ensuring the deformation transverse. Such gripping and driving means consist, for example, of pliers, fingers, suction cups, carriage or the like or other driven in displacement by means of motor, gear motor, piston or others, directly or by the trolley intermediate, endless chain, threaded screws etc ... Such gripping and drive means are known or within the reach of those skilled in the art in the technical field of packaging and, for this reason, are not described further ,. These input and drive means can be the subject of numerous alternative embodiments fulfilling the indicated function.

On se réfère maintenant aux figures 1A à 1E qui illustrent l'invention dans une forme possible de mise en oeuvre , les objets 3 sont mobiles et déplaçables relativement les uns par rapport aux autres longitudinalement et transversalement horizontalement entre d'une part une position initiale (figure 1A) ou ils sont écartés longitudinalement et transversalement horizontalement les uns des autres dans une configuration rappelant la configuration finale en autorisant l'amenée et le passage notamment longitudinal (ou transversal ou autre), entre eux, du tronçon 7 de bande à plat dans une configuration rappelant la configuration finale, grâce aux moyens de saisie et d'entraînement et d'autre part une position finale (figure 1E) où ils sont rapprochés les uns des autres longitudinalement et transversalement, dans leur configuration finale ou correspondant au moins sensiblement à la configuration finale des objets 3 à emballer.Reference is now made to FIGS. 1A to 1E which illustrate the invention in a possible form of implementation, the objects 3 are movable and displaceable relatively to each other longitudinally and transversely horizontally between on the one hand an initial position ( Figure 1A) or they are spaced longitudinally and transversely horizontally from one another in a configuration recalling the final configuration by allowing the supply and the passage, in particular longitudinal (or transverse or other), between them, of section 7 of strip flat in a configuration reminiscent of the final configuration, thanks to the gripping and driving means and on the other hand a final position (FIG. 1E) where they are brought close to each other longitudinally and transversely, in their final configuration or corresponding at least substantially to the final configuration of the objects 3 to be packaged.

Pour passer de la position initiale à la position finale, les objets 3 sont entraînés relativement les uns par rapport aux autres selon une cinématique et des moyens appropriés pouvant faire l'objet de nombreuses variantes. Par exemple, dans le cas d'un groupe de six objets 3 répartis en deux lignes et trois rangées (avec la désignation LiRj telle que définie plus haut), on place d'abord un tronçon 7 entre les objets 3 en position initiale, (figure 1A) notamment par un déplacement longitudinal horizontal (selon la flèche A) ; puis, (figure 1B) on rapproche les deux lignes d'objets 3 (respectivement L1R1, L1R2, L1R3 d'une part, L2R1, L2R2, L2R3 d'autre part) jusqu'à ce qu'ils soient appliqués sur le tronçon 7 de bande, de part et d'autre (flèches C). Puis on opère un pivotement d'ensemble des deux objets 3 centraux L1R2 et L2R2, c'est-à-dire de la rangée centrale, de 180° au moins sensiblement autour d'un axe vertical médian (figures 1C et 1D) (flèche D) ce qui a pour effet de conformer le tronçon 7 de bande pour lui donner une forme générale de S dans sa partie transversale médiane. Puis, on opère un rapprochement relatif longitudinal horizontal des objets 3 d'extrémité L1R1, L2R1 d'une part, L1R3, L2R3 d'autre part sur les objets 3 centraux L1R2 et L2R2, jusqu'à amener les objets 3 à proximité immédiate les uns des autres contre ou sensiblement contre le tronçon 7 de bande ce qui a pour effet de déformer ainsi les parties transversales d'extrémité du tronçon 7 (flèches E) (figure 1E). Le dispositif comporte, à cet effet, des moyens de guidage, saisie, entraînement, déplacement, de blocage des objets 3 relativement les uns par rapport aux autres tels que des glissières, des chaînes sans fin , des moteurs ou moto-réducteurs, des chariots, des ventouses de succion, des tapis mobiles, des pinces ou tout moyen apte à agir positivement sur les objets 3 pour d'une part les bloquer ou les maintenir dans certaines configurations relatives (notamment la position ou configuration initiale écartée et la position ou configuration finale rapprochée) et, d'autre part les déplacer selon des séquences contrôlées d'une position ou configuration à une autre.To pass from the initial position to the final position, the objects 3 are driven relatively with respect to each other according to kinematics and appropriate means which can be the subject of numerous variants. For example, in the case of a group of six objects 3 distributed in two lines and three rows (with the designation LiRj as defined above), first place a section 7 between the objects 3 in the initial position, ( FIG. 1A) in particular by a horizontal longitudinal displacement (according to arrow A); then (FIG. 1B) the two lines of objects 3 are brought together (respectively L1R1, L1R2, L1R3 on the one hand, L2R1, L2R2, L2R3 on the other hand) until they are applied to the section 7 tape, on both sides (arrows C). Then there is an overall pivoting of the two central objects 3 L1R2 and L2R2, that is to say of the central row, by 180 ° at least approximately around a median vertical axis (Figures 1C and 1D) (arrow D) which has the effect of conforming the section 7 of strip to give it a general shape of S in its median transverse part. Then, a horizontal longitudinal relative bringing together of the end objects 3 L1R1, L2R1 on the one hand, L1R3, L2R3 on the other hand on the central objects 3 L1R2 and L2R2 is carried out, until bringing the objects 3 in the immediate against each other or substantially against the section 7 of the strip, which has the effect of thus deforming the transverse end portions of the section 7 (arrows E) (FIG. 1E). The device comprises, for this purpose, means for guiding, gripping, driving, moving, blocking the objects 3 relatively to each other such as slides, endless chains, motors or geared motors, carriages , suction cups, movable belts, clamps or any means capable of acting positively on the objects 3 in order to block or maintain them in certain relative configurations (in particular the initial position or configuration discarded and the position or configuration close final) and, on the other hand, move them according to controlled sequences from one position or configuration to another.

Dans la forme de réalisation qui vient d'être décrite, les moyens propres à amener le tronçon 7 de bande à présenter une forme de surface réglée à partir de la courbe de référence 8 c'est-à-dire les moyens de déformation transversale du support 7 de bande sont placés à proximité des moyens support 9 et comprennent les objets 3 eux-mêmes, faisant fonction de gabarits pour la conformation de l'intercalaire 1, avant que d'y être emballé. La même forme de réalisation est applicable avec ces moyens de déformation transversale écartés des moyens de support 9 et comprenant des gabarits au lieu et place des objets 3 dans leur fonction de gabarits, le dispositif comprenant alors des moyens de transfert d'un intercalaire 1 conformé depuis les gabarits jusqu'au groupe 4 d'objets 3 qui se trouve alors dans sa configuration finale présentant l'espace 2 juste nécessaire pour le passage, dans le sens transversal, de l'intercalaire 1 conformé.In the embodiment which has just been described, the means suitable for causing the strip section 7 to have a surface shape adjusted from the reference curve 8, that is to say the transverse deformation means of the strip support 7 are placed near the support means 9 and include the objects 3 themselves, acting as templates for the conformation of the interlayer 1, before being packed there. The same embodiment is applicable with these transverse deformation means separated from the support means 9 and comprising jigs instead of and places objects 3 in their jigs function, the device then comprising means for transferring a shaped interlayer 1 from the templates to the group 4 of objects 3 which is then in its final configuration having the space 2 just necessary for the passage, in the transverse direction, of the interlayer 1 shaped.

Dans une forme de réalisation possible, ces moyens de transfert comprennent au moins un doigt ou similaire horizontal et de direction générale perpendiculaire au tronçon 7 de bande à plat non conformé mobile doublement, d'une part longitudinalement par rapport à leurs axes c'est-à-dire transversalement par rapport aux axes 10 des objets 3 notamment dans un plan horizontal de manière à pouvoir être soit placé contre le bord longitudinal 12 notamment supérieur du tronçon 7 de bande conformé et ainsi interférer avec lui de manière à pouvoir agir sur lui, soit escamoté écarté, d'autre part, transversalement, notamment verticalement c'est-à-dire parallèlement du tronçon 7 et à la direction transversale T ou aux axes 10, vers le haut ou le bas de manière a pouvoir (en combinaison avec le mouvement longitudinal) soit entraîner l'intercalaire 1 conformé vers le bas des gabarits aux objets 3, soit revenir vers le haut en position escamotée. De tels moyens de transfert peuvent être réalisés différemment et sont connus ou à la portée de l'homme du métier dans la technique de l'emballage. Ils ne sont donc pas décrits plus avant.In one possible embodiment, these transfer means comprise at least one finger or the like horizontal and of general direction perpendicular to the section 7 of strip of flat non-conformed flat movable doubly, on the one hand longitudinally relative to their axes that is that is to say transversely with respect to the axes 10 of the objects 3 in particular in a horizontal plane so as to be able to be either placed against the longitudinal edge 12 in particular upper of the section 7 of shaped strip and thus to interfere with it so as to be able to act on it, either retracted apart, on the other hand, transversely, in particular vertically, that is to say parallel to the section 7 and to the transverse direction T or to the axes 10, upwards or downwards so as to be able (in combination with the longitudinal movement) either drive the interlayer 1 shaped downwards from the templates to the objects 3, or return upwards in the retracted position. Such transfer means can be produced differently and are known or within the reach of the skilled person in the packaging technique. They are therefore not described further.

Dans une autre forme possible de mise en oeuvre (figures 2A à 2E), la séquence opératoire est légèrement différente de celle qui à été décrite en référence aux figures 1A à 1E. Cette séquence s'applique à l'une comme à l'autre des deux variantes considérées : mise en place directe de l'intercalaire 1 sur les objets 3 assurant leur conformation ou utilisation intermédiaire de gabarits. Dans la séquence des figures 2A à 2E, les objets 3 (ou gabarits- cette précision en forme de variante n'étant par la suite plus répétée) sont, originellement (figure 2A) dans leur position finale, le tronçon 7 de bande étant à l'aplomb de l'espace entre les deux lignes d'objets 3. Par un mouvement vertical descendant selon les flèches F, le tronçon 7 est introduit dans cet espace (figure 2B). Puis, les objets 3 d'extrémité L1R1, L2R1, L1R3, L2R3, L2R3) sont écartés relativement horizontalement et longitudinalement des objets 3 centraux (figure 2D) comme précédemment selon la flèche D (figure 1C). Et, enfin, on rapproche longitudinalement et horizontalement, les objets 3 d'extrémité (figure 2E), comme précédemment selon les flèches E (figure 1E).In another possible form of implementation (FIGS. 2A to 2E), the operating sequence is slightly different from that which has been described with reference to FIGS. 1A to 1E. This sequence applies to both of the two variants considered: direct installation of the interlayer 1 on the objects 3 ensuring their conformation or intermediate use of templates. In the sequence of FIGS. 2A to 2E, the objects 3 (or templates - this precision in the form of a variant being subsequently no longer repeated) are, originally (FIG. 2A) in their final position, the section 7 of strip being at the vertical alignment of the space between the two lines of objects 3. By a vertical downward movement according to the arrows F, the section 7 is introduced into this space (FIG. 2B). Then, the end objects 3 L1R1, L2R1, L1R3, L2R3, L2R3) are separated relatively horizontally and longitudinally from the central objects 3 (FIG. 2D) as previously according to arrow D (FIG. 1C). And, finally, the end 3 objects (FIG. 2E) are brought together longitudinally and horizontally, as before according to the arrows E (FIG. 1E).

On se réfère, maintenant, aux figures 3 à 7 qui illustrent, plus en détail, un dispositif pour la réalisation et la mise en place d'un intercalaire 1, correspondant au cas de la mise en oeuvre qui vient d'être décrite. Ce dispositif est incorporé, généralement, à une machine ou à une installation d'emballage, non représentée. Seuls certains organes du dispositif sont représentés. Le dispositif comporte (figure 3) un bâti 14 supportant en position médiane supérieure les moyens de déformation transversale comprennent des moyens 15 de déplacement relatif longitudinal horizontal des objets 3 d'extrémité, dans un sens ou le sens opposé (figure 4) et des moyens 16 de rotation à 180° des objets 3 centraux (figures 5, 6, 7).Reference is now made to FIGS. 3 to 7 which illustrate, in more detail, a device for producing and placing an insert 1, corresponding to the case of the implementation which has just been described. This device is incorporated, generally, in a machine or in a packaging installation, not shown. Only certain organs of the device are represented. The device comprises (FIG. 3) a frame 14 supporting in the upper middle position the transverse deformation means comprise means 15 for relative longitudinal horizontal movement of the end objects 3, in one direction or the opposite direction (FIG. 4) and means 16 of 180 ° rotation of the 3 central objects (Figures 5, 6, 7).

Préférentiellement, les moyens 16 comprennent également des moyens pour la montée ou la descente des objets 3 centraux. les moyens 15, 16 sont commandés, par exemple à partir de cames de commande 17 portées par le bâti 14, entraînées convenablement à rotation. Des systèmes mécaniques tels que bielle, manivelle ou autre et/ou pneumatiques, ou autre sont associées aux cames 27 pour transmettre les mouvements appropriés aux moyens 15 et 16 soit, respectivement les systèmes 18, 19 (figure 3). Le système 18 (figure 4) peut comporter par exemple, une prise de commande de came 20, commandée par une came 17 agissant sur un palonnier 20a d'inversion du mouvement pour assurer une commande unique à deux coulisseaux 21 mobiles à coulissement horizontalement, supportant rigidement deux bras verticaux 22, supportant rigidement, eux-mêmes, deux supports 23 dirigés face à face, coaxialement, horizontalement, terminés par des ventouses 24 associées à une commande pneumatique. Les ventouses 24 agissent sur et peuvent saisir et entraîner les objets 3 d'extrémité, de manière que par actionnement de la came 17 correspondante et via la commande 20 les coulisseaux 21 soient entraînés à coulissement dans un sens ou dans l'autre horizontalement et longitudinalement, ce qui provoque le déplacement concomitant des ventouses 24 donc des objets 3 qu'elles saisissent.Preferably, the means 16 also include means for raising or lowering the central objects 3. the means 15, 16 are controlled, for example from control cams 17 carried by the frame 14, suitably driven in rotation. Mechanical systems such as connecting rod, crank or other and / or pneumatic, or other are associated with the cams 27 for transmitting the appropriate movements to the means 15 and 16, or respectively the systems 18, 19 (FIG. 3). The system 18 (FIG. 4) may include, for example, a cam control socket 20, controlled by a cam 17 acting on a spreader 20a for reversing the movement to provide a single control with two movable slides 21 sliding horizontally, rigidly supporting two vertical arms 22, rigidly supporting, themselves, two supports 23 directed face to face, coaxially, horizontally, terminated by suction cups 24 associated with a pneumatic control. The suction cups 24 act on and can grip and drive the end objects 3, so that by actuation of the corresponding cam 17 and via the control 20 the slides 21 are driven to slide in one direction or the other horizontally and longitudinally , which causes the concomitant displacement of the suction cups 24 therefore of the objects 3 which they grasp.

Le système 19 (figures 5, 6, 7) peut comporter, par exemple un coulisseau 25 en prise avec une came 17, agissant sur une pignonerie 26 agissant sur des moyens porteurs 27 guidés à rotation par des moyens de guidage 28.The system 19 (FIGS. 5, 6, 7) may comprise, for example a slide 25 engaged with a cam 17, acting on a pinion 26 acting on carrier means 27 guided in rotation by guide means 28.

Les moyens porteurs 27 sont également associés à un coulisseau 29 monté coulissant verticalement, entraîné vers le haut ou le bas par un vérin 30 ou équivalent.The carrier means 27 are also associated with a slide 29 mounted to slide vertically, driven up or down by a jack 30 or equivalent.

Les moyens porteurs 27 sont constitués par un cadre 31 disposé horizontalement des mors 32 coulissant horizontalement au moyens de vérins 33 ou équivalent, aptes -lorsqu'ils coopèrent- à venir enserrer le goulot ou bouchon 6 d'un objet 3 ou des objets 3 centraux pour les saisir fermement et permettre, notamment leur rotation à l'encontre du tronçon de base 7.The carrying means 27 are constituted by a frame 31 disposed horizontally with the jaws 32 sliding horizontally by means of jacks 33 or equivalent, suitable -when they cooperate- to grip the neck or plug 6 of an object 3 or central objects 3 to grip them firmly and allow, in particular their rotation against the base section 7.
