Abstract

The form is unfolded and, to this effect, two working faces of the folded form are grasped and then a relative displacement of the two working faces is effected so as to bring them into the final relative position of the container, and subsequently the container is finished, that is to say its base is formed. The unfolding movement is a rotation and the two working faces are mutually adjacent and define an edge, in particular downstream. <IMAGE>

Description

Procédé et machine pour constituer un contenant de forme générale parallélépipédique, tel qu'un étui ou une caisse américaine, à partir d'une forme aplatie.Method and machine for making a container of generally parallelepiped shape, such as a case or an American case, from a flattened shape.

La présente invention concerne un procédé et une machine pour constituer un contenant de forme générale parallélépipédique, tel qu'un étui ou une caisse dite américaine, à partir d'une forme aplatie., correspondant au contenant, plié le long de ses arêtes.The present invention relates to a method and a machine for constituting a container of generally rectangular shape, such as a case or a so-called American box, from a flattened shape., Corresponding to the container, folded along its edges.

Le domaine technique auquel s'intéresse l'invention est celui des contenants constitués à partir d'une forme aplatie. De tels contenants sont réalisés notamment en carton présentant une certaine tenue. Les dimensions peuvent être comprises, selon les besoins entre quelques centimètres environ et au moins un mètre environ. La forme aplatie comporte des lignes de pliage à l'endroit des arêtes du contenant. De façon connue, un tel contenant comporte quatre faces latérales, un fond et un couvercle. Le fond comporte au moins un rabat et préférentiellement quatre rabats venant dans le prolongement des faces latérales. Il en est de même en ce qui concerne le couvercle. La forme se présente sous forme aplatie, comportant deux plans correspondant chacun à deux faces latérales adjacentes du contenant et, dans le cas d'un contenant comportant quatre rabats de fond et quatre rabats de couvercle, à deux rabats de fond et deux rabats de couvercle voisins.The technical field in which the invention is concerned is that of containers made from a flattened shape. Such containers are made in particular of cardboard having a certain resistance. The dimensions can be included, depending on requirements, between a few centimeters and at least about one meter. The flattened shape has fold lines at the edges of the container. In known manner, such a container has four side faces, a bottom and a cover. The bottom comprises at least one flap and preferably four flaps coming in the extension of the lateral faces. The same applies to the cover. The shape is in flattened form, comprising two planes each corresponding to two adjacent lateral faces of the container and, in the case of a container comprising four bottom flaps and four lid flaps, two bottom flaps and two lid flaps neighbors.

On connaît déjà des procédés et des machines pour constituer un contenant à partir d'une telle forme. Dans ces procédés et machines connus, les formes pliées sont placées dans des moyens de stockage où elles sont superposées et empilées.Methods and machines are already known for constituting a container from such a form. In these known methods and machines, the folded forms are placed in storage means where they are superimposed and stacked.

Dans une phase initiale du procédé, on extrait une forme des moyens de stockage. Dans une phase ultérieure, on déplie la forme et dans une phase finale on réalise la finition du contenant, c'est-à-dire la constitution de son fond.In an initial phase of the process, a form of the storage means is extracted. In a later phase, the shape is unfolded and in a final phase, the container is finished, that is to say the constitution of its bottom.

On connaît plusieurs modes de réalisation de la phase de dépliage de la forme. Dans un premier mode de réalisation connue, on saisit deux faces de travail de la forme pliée, parallèles et opposées l'une à l'autre notamment les faces horizontales inférieure et horizontale supérieure. On procède ensuite à un mouvement de translation relatif de ces phases qui tout en restant parallèles l'une à l'autre sont écartées et placées à l'aplomb l'une de l'autre. Dans une autre forme d'exécution connue, on agit sur les deux arêtes de pliage opposées de la forme et on les sollicite l'une en direction de l'autre pour ouvrir cette forme.Several embodiments are known of the unfolding phase of the form. In a first known embodiment, two working faces of the folded shape are grasped, parallel and opposite to each other, in particular the lower horizontal and upper horizontal faces. One then proceeds to a relative translational movement of these phases which, while remaining parallel to one another, are spaced apart and placed perpendicular to one another. In another known embodiment, one acts on the two opposite folding edges of the form and is urged one towards the other to open this form.

Ces procédés et machines connus présentent généralement l'inconvénient d'être adaptés au cas spécifique d'un contenant, notamment ses dimensions, et ne sont donc pas conçus pour permettre une modification commode ou de grande ampleur du type de contenant.These known methods and machines generally have the disadvantage of being adapted to the specific case of a container, in particular its dimensions, and are therefore not designed to allow a convenient or large-scale modification of the type of container.

Dans les procédés et machines connus, il est prévu des moyens de guidage, traversés par la forme après son dépliage, et permettant son maintien d'équerre avant et pendant la constitution du fond. Ces moyens de guidage se révèlent complexes, difficilement réglables selon le type de contenant et le passage de la forme ouverte sur ces moyens de guidage est une opération délicate.In known methods and machines, there are provided guide means, traversed by the form after its unfolding, and allowing its maintenance square before and during the constitution of the bottom. These guide means prove to be complex, difficult to adjust according to the type of container and the passage of the open form over these guide means is a delicate operation.

La présente invention vise à remédier à ces différents inconvénients tout en proposant un procédé de constitution d'un contenant du type indiqué qui fonctionne à fréquence élevée et une machine pour la mise en oeuvre du procédé d'encombrement restreint, malgré la fréquence obtenue et les possibilités de réglage.The present invention aims to remedy these various drawbacks while proposing a method of constituting a container of the indicated type which operates at high frequency and a machine for implementing the method of limited space, despite the frequency obtained and the adjustment possibilities.

La présente invention propose donc un procédé pour constituer un contenant de forme générale parallélépipédique à partir d'une forme aplatie, dans lequel dans une première phase, on déplie la forme et à cet effet, on saisit respectivement deux faces de travail de la forme pliée et ensuite on réalise un déplacement relatif des deux faces de travail - dit mouvement de dépliage - pour amener les deux faces de travail dans la position relative définitive du contenant et, dans une seconde phase ultérieure, on réalise la finition du contenant c'est-à-dire la constitution de son fond. Dans ce procédé, le mouvement de dépliage est une rotation et les deux faces de travail adjacentes entre elles et définissant une arête notamment aval.The present invention therefore provides a method for constituting a container of generally parallelepipedal shape from a flattened shape, in which in a first phase, the shape is unfolded and for this purpose, two working faces of the folded shape are gripped respectively. and then a relative displacement of the two working faces is made - known as the unfolding movement - to bring the two working faces into the final relative position of the container and, in a second subsequent phase, the container is finished. ie the constitution of its fund. In this method, the unfolding movement is a rotation and the two working faces adjacent to each other and defining a particularly downstream edge.

Selon d'autres caractéristiques du procédé, l'extraction et l'amenée d'une forme sont réalisées par translation de cette forme dans son propre plan, en la saisissant par une zone de saisie opposée aux faces de travail, notamment l'arête amont. Pendant toute la phase de finition, on maintient le contenant essentiellement par ses deux faces de travail dans leur position relative définitive. On traite simultanément plusieurs formes et/ou contenants, notamment une première forme en phase d'extraction et d'amenée, une deuxième forme en phase de dépliage et une troisième forme en phase de finition.According to other characteristics of the process, the extraction and the supply of a form are carried out by translation of this form in its own plane, by gripping it by a gripping zone opposite to the working faces, in particular the upstream edge. . During the entire finishing phase, the container is maintained essentially by its two working faces in their final relative position. Several forms and / or containers are treated simultaneously, in particular a first form in the extraction and supply phase, a second form in the unfolding phase and a third form in the finishing phase.

La présente invention propose également une machine pour la mise en oeuvre du procédé comportant des moyens de stockage de formespliées , empilées, superposées, auxquels sont associés des moyens d'amenée de formes ; des moyens de dépliage d'une forme comprenant des moyens de saisie de deux faces de travail de la forme et des moyens pour réaliser un déplacement relatif des moyens de saisie ; et des moyens de finition du contenant notamment de constitutiona de son fond auxquels sont associés des moyens de maintien du contenant. Suivant l'invention, les moyens de saisie sont adjacents entre eux pour pouvoir être associés à deux faces également adjacentes de la forme et les moyens pour réaliser un déplacement relatif des moyens de saisie sont des moyens pour réaliser au moins un pivotement de ces moyens.The present invention also provides a machine for implementing the method comprising means for storing folded, stacked, superimposed shapes, with which means for feeding shapes are associated; means for unfolding a shape comprising means for gripping two working faces of the shape and means for carrying out a relative displacement of the gripping means; and means for finishing the container, in particular for constituting its bottom, with which means for holding the container are associated. According to the invention, the gripping means are adjacent to each other so that they can be associated with two faces also adjacent to the shape and the means for carrying out a relative displacement of the gripping means are means for carrying out at least one pivoting of these means.

Selon d'autres caractéristiques de la machine suivant l'invention, les nn- yens de saisie constituent également les moyens de maintien et la machine comporte deux longerons semblables, parallèles, côte à côte, guidés à coulissement axial par des. moyens de coulissement, entraînés en translation xiale, alternativement dans un sens et dans l'autre par des moyens d'entraînement, associés fonctionnellement l'un à l'autre pour être déplacés dans deux sens opposés, chacun des longerons constituant éventuellement respectivement dans sa partie amont et dans sa partie aval des moyens d'appui d'une forme ou d'un contenant et comportant à sa partie extrême libre amont les moyens d'amenée et à sa partie extrême libre aval les moyens de saisie ou de maintien.According to other characteristics of the machine according to the invention, the gripping pins also constitute the holding means and the machine comprises two similar longitudinal members, parallel, side by side, guided in axial sliding by. sliding means, driven in xial translation, alternately in one direction and in the other by drive means, functionally associated with each other to be moved in two opposite directions, each of the side members possibly constituting respectively in its upstream part and in its downstream part of the support means of a form or of a container and comprising at its upstream end free part the supply means and at its downstream end free part the gripping or holding means.

Suivant l'invention, il est proposé un procédé et une machine pour constituer un contenant C de forme générale parallélépipédique, tel qu'un étui ou une caisse dite américaine, à partir d'une forme F initialement aplatie, correspondant au contenant C plié le long de ses arêtes. Pour la compréhension du texte qui suivra, on se réfère aux figures la, Ib, lc. La figure la représente la forme F qui comprend deux flancs superposés supérieur fs et inférieur fi réunis entre eux par deux arêtes, une arête amont am et une arête aval av. Chaque flanc fs et fi est composé de deux faces latérales adjacentes du contenant, soit les faces fl's et fl"s pour le flanc fs et les faces fl'i et fl"i pour le flanc fi. Sur chacun des flanc fs, fi se trouve une arête respectivement as et ai. La forme F comporte encore le fond fo et le couvercle co du contenant qui dans l'exemple considéré sont constitués chacun par quatre rabats, deux associés au flanc fs et deux associés au flanc fo, venant dans le prolongement des faces latérales respectives.According to the invention, there is provided a method and a machine for constituting a container C of generally parallelepiped shape, such as a case or a so-called American box, from a form F initially flattened, corresponding to the container C folded along its edges. For the understanding of the following text, we refer to Figures la, Ib, lc. FIG. 1a represents the form F which comprises two superposed flanks upper fs and lower fi joined together by two edges, an upstream edge am and a downstream edge av. Each flank fs and fi is composed of two adjacent lateral faces of the container, that is to say the faces fl's and fl "s for the flank fs and the faces fl'i and fl" i for the flank fi. On each of the flanks fs, fi is an edge respectively as and ai. The form F also includes the bottom fo and the cover co of the container which in the example considered each consist of four flaps, two associated with the flank fs and two associated with the flank fo, coming in the extension of the respective lateral faces.

La figure lc représente le contenant C, une fois réalisé, présentant sa forme générale parallélépipédique, le fond étant constitué.FIG. 1c shows the container C, once produced, having its general rectangular shape, the bottom being formed.

La figure lb représente une étape intermédiaire entre la forme F et le contenant C à savoir, la forme dépliée FD dans laquelle les faces latérales fl's, fm"s, fm'i, fl"i sont à équerre tandis que le fond fo et le couvercle co ne sont pas encore constitués dans le prolongement de ces faces latérales.FIG. 1b represents an intermediate step between the form F and the container C, namely, the unfolded form FD in which the side faces fl's, fm "s, fm'i, fl" i are square while the bottom fo and the co cover are not yet formed in the extension of these side faces.

Le procédé suivant l'invention s'applique à des formes pliées F placées notamment empilées et superposées, en particulier horizontalement , dans des moyens de stockage 1.The method according to the invention applies to folded forms F placed in particular stacked and superimposed, in particular horizontally, in storage means 1.

Dans une phase initiale du procédé, on extrait une forme pliée F des moyens de stockage et on l'amène pour la phase ultérieure du procédé. Cette phase d'extraction et d'amenée est illustrée sur les figures 2c, 2d, 3c et 3d par le fond F n+2.In an initial phase of the process, a folded form F is extracted from the storage means and brought to the later phase of the process. This extraction and supply phase is illustrated in FIGS. 2c, 2d, 3c and 3d by the background F n + 2.

Dans une phase ultérieure du procédé, on déplie la forme et à cet effet, on saisit respectivement deux faces de travail ft de la forme pliée F et ensuite on réalise un déplacement relatif des deux faces de travail ft - dit mouvement de dépliage - pour amener les deux faces de travail ft dans la position relative définitive du contenant C. Cette phase est illustrée sur les figures 2a, 2b, 3a, 3b, par la forme F n+1 ou forme dépliée FD n+1.In a later phase of the process, the shape is unfolded and for this purpose, two working faces ft of the folded form F are respectively grasped and then a relative displacement of the two working faces ft is made - called unfolding movement - to bring the two working faces ft in the final relative position of the container C. This phase is illustrated in FIGS. 2a, 2b, 3a, 3b, by the form F n + 1 or the unfolded form FD n + 1.

Dans une phase ultime du procédé suivant l'invention on réalise la finition du contenant C c'est-à-dire la constitution de son fond fo. Cette phase est illustrée par la forme dépliée FD n+1 sur les figures 2c, 2d, 2e, 3c, 3d et 3e.In a final phase of the process according to the invention, the container C is finished, that is to say the constitution of its bottom fo. This phase is illustrated by the unfolded form FD n + 1 in FIGS. 2c, 2d, 2e, 3c, 3d and 3e.

Suivant l'invention, le mouvement de dépliage est une rotation et les deux faces de travail ft adjacentes entre elles. En particulier, les deux faces de travail ft sont les faces fl"s et fl'i définissant entre elles l'arête aval av. Dans la forme pliée F, ces deux faces de travail ft sont appliquées l'une contre l'autre. Dans la forme dépliée FD et dans le contenant C, ces deux faces de travail sont perpendiculaires l'une à l'autre. L'axe 2 du mouvement de dépliage est donc confondu avec l'arête aval av. Comme on le verra par la suite, l'arête aval av est, dans la machine, l'arête frontale de la forme F.According to the invention, the unfolding movement is a rotation and the two working faces ft adjacent to each other. In particular, the two working faces ft are the faces fl "s and fl'i defining between them the downstream edge av. In the folded form F, these two working faces ft are applied one against the other. In the unfolded form FD and in the container C, these two working faces are perpendicular to each other, the axis 2 of the unfolding movement is therefore confused with the downstream edge av. next, the downstream edge av is, in the machine, the front edge of the form F.

Egalement, suivant l'invention, on réalise l'extraction et l'amenée dans la première phase du procédé par un mouvement de translation de la forme F, dans son propre plan, en la saisissant par une zone de saisie opposée aux faces de travail, notamment l'arête amont am.Also, according to the invention, the extraction and the supply are carried out in the first phase of the process by a translational movement of the form F, in its own plane, by gripping it by a gripping zone opposite to the working faces. , notably the upstream ridge am.

Dans la description, on entend par saisir une face ou une zone d'une forme ou d'un contenant, faire interférer un organe approprié avec cette face ou zone de manière que la mise en oeuvre de cet organe, notamment son déplacement, provoque le déplacement concomittant de cette face ou zone.In the description, the term “grasping a face or an area of a shape or a container” means making an appropriate member interfere with this face or area so that the implementation of this member, in particular its displacement, causes the concomitant displacement of this face or zone.

Suivant l'invention, pendant la phase finale de finition, on maintient le contenant C, essentiellement par ses deux faces de travail ft, dans la position relative définitive. Autrement dit, on poursuit la saisie effectuée dans la phase de dépliage, pendant la phase de finition.According to the invention, during the final finishing phase, the container C is maintained, essentially by its two working faces ft, in the final relative position. In other words, the entry made in the unfolding phase is continued, during the finishing phase.

La phase de finition peut être combinée à une phase de remplissage et de fermeture du contenant.The finishing phase can be combined with a filling and closing phase of the container.

Suivant l'invention, on traite simultanément plusieurs formes et/ou contenant. Ainsi une première forme est en phase d'extraction et d'amenée, tandis qu'une deuxième forme, notamment celle qui chronologiquement précède immédiatement la première forme,.est dans la phase de dépliage et une troisième forme dépliée - notamment celle qui chronologiquement précède immédiatement la deuxième forme - est dans la phase de finition. Cette caractéristique permet au procédé de fonctionner à une fréquence élevée.According to the invention, several forms and / or container are treated simultaneously. Thus a first form is in the extraction and supply phase, while a second form, in particular that which chronologically immediately precedes the first form, is in the unfolding phase and a third unfolded form - in particular that which chronologically precedes immediately the second form - is in the finishing phase. This feature allows the process to operate at a high frequency.

Comme on l'a compris, dans la phase de dépliage et de finition, la forme dépliée, respectivement le contenant est saisi et maintenu par des faces de travail ft notamment au voisinage immédiat de l'arête aval av. Cette disposition permet au procédé d'être appliqué à des formes de dimensions très variables.As has been understood, in the unfolding and finishing phase, the unfolded shape, respectively the container is grasped and held by working faces ft in particular in the immediate vicinity of the downstream edge av. This arrangement allows the process to be applied to shapes of very variable dimensions.

Sur les figures 2a et 3a, est illustré le procédé suivant l'invention, des formes F n+2, ... F n+6 ... étant placées dans les moyens de stockage, une forme F n+1 étant au début de sa phase de dépliage, le contenant Cn étant à la fin de la phase de finition. Par conséquent, on commence alors à saisir les deux faces de travail ft de la forme F n+1. Quant aux deux faces de travail ft du contenant Cn, elles sont encore maintenues.In FIGS. 2a and 3a, the process according to the invention is illustrated, forms F n + 2, ... F n + 6 ... being placed in the storage means, a form F n + 1 being at the start of its unfolding phase, the container Cn being at the end of the finishing phase. Consequently, we then begin to grasp the two working faces ft of the form F n + 1. As for the two working faces ft of the container Cn, they are still maintained.

Sur les figures 2b et 3b est illustrée la phase de dépliage proprement dite, en ce qui concerne la forme F n+1. Dans cette phase intervient le déplacement relatif des deux faces de travail ft autour de l'axe 2. La forme F n+1 initialement aplatie se déforme, son contour en élévation étant celui d'un parallélogramme (en tireté sur les figures 2b et 3b). jusqu'à présenter un contour rectangulaire (en traits pleins). Dans cette pyase, la forme F n+1 est à l'arrêt. Le contenant Cn est également à l'arrêt et la phase de finition étant terminée, on cesse de saisir les deux faces de travail ft. Sur les figures 2c et 3c est illustrée la phase d'extraction et d'amenée de la forme F n+2. Dans cette phase, la forme dépliée FD n+1 entre dans sa phase de finition. Dans cette phase, la forme F n+2 et la forme dépliée FD n+1 sont déplacées simultanément et dans le même sens. Le contenant Cn est en instance d'évacuation.In FIGS. 2b and 3b is illustrated the unfolding phase proper, as regards the form F n + 1. In this phase, the relative displacement of the two working faces ft takes place around the axis 2. The shape F n + 1 initially flattened deforms, its outline in elevation being that of a parallelogram (in dashed lines in FIGS. 2b and 3b ). until presenting a rectangular outline (in solid lines). In this p Yase, form F n + 1 is stopped. The container Cn is also at a standstill and the finishing phase having been completed, the two working faces ft are no longer gripped. In FIGS. 2c and 3c is illustrated the extraction and supply phase of the form F n + 2. In this phase, the unfolded form FD n + 1 enters its finishing phase. In this phase, the form F n + 2 and the unfolded form FD n + 1 are moved simultaneously and in the same direction. The container Cn is being evacuated.

Sur les figures 2d et 3d, la forme F n+2 est toujours dans sa phase d'extraction et d'amenée et la forme dépliée FD n+1 également dans sa phase de finition.In Figures 2d and 3d, the form F n + 2 is always in its extraction and supply phase and the unfolded form FD n + 1 also in its finishing phase.

Cette phase de finition peut comporter plusieurs étapes successives soit une étape initiale de fermeture des rabats (figures 2c et 3c, et une étape intermédiaire d'encollage (figure 2d et 3d) et enfin une étape finale de soli- darisation et pressage des rabats (figures 2e et 3e). Dans ce cas, le contenant Cn a été évacué et la forme F n+2 se trouve à la fin de sa phase d'extraction et d'amenée.This finishing phase may include several successive steps, namely an initial step of closing the flaps (FIGS. 2c and 3c, and an intermediate step of gluing (FIGS. 2d and 3d) and finally a final step of solidifying and pressing the flaps ( Figures 2e and 3e) In this case, the container Cn has been evacuated and the form F n + 2 is at the end of its extraction and supply phase.

Le cycle peut ensuite être répété.The cycle can then be repeated.

Sur les figures 2c, les flèches g indiquent la fermeture des rabats, la flèche h l'opération d'encollage et les flèches i, le pressage et la fermeture définitive des rabats.In FIGS. 2c, the arrows g indicate the closing of the flaps, the arrow h the gluing operation and the arrows i, the pressing and the final closing of the flaps.

L'invention concerne également une machine pour la mise en oeuvre du procédé qui comporte les moyens de stockage 1 pour des formes pliées, empilées et superposées, auxquelles sont associées des moyens d'amenée 3 de ces formes ; des moyens 4 de dépliage d'une forme F ; et des moyens de finition 5 d'un contenant C notamment de constitution de son fond fo, auxquels sont associés des moyens de maintien du contenant.The invention also relates to a machine for implementing the method which comprises the storage means 1 for folded, stacked and superimposed shapes, with which are associated feeding means 3 for these shapes; means 4 for unfolding a form F; and means 5 for finishing a container C, in particular for constituting its bottom fo, to which are associated means for holding the container.

Les moyens de dépliage 4 comprennent des moyens 6 de saisie de deux faces de travail ft de la forme F et des moyens 7 pour réaliser un déplacement relatif des moyens de saisie 6.The unfolding means 4 comprise means 6 for gripping two working faces ft of the form F and means 7 for carrying out a relative displacement of the gripping means 6.

Suivant l'invention, les moyens de saisie 6 sont adjacents entre eux pour pouvoir être associés à deux faces également adjacentes de la forme F, ainsi qu'il a été expliqué précédemment. Les moyens 7 sont des moyens pour réaliser au moins un pivotement des moyens de saisie 6 notamment autour de l'axe 2. Les moyens de maintien associés aux moyens de finition 5 sont constitués par les moyens de saisie 6.According to the invention, the gripping means 6 are adjacent to each other so that they can be associated with two equally adjacent faces of the form F, as explained above. The means 7 are means for carrying out at least one pivoting of the gripping means 6 in particular around the axis 2. The holding means associated with the means of finish 5 are constituted by the gripping means 6.

Dans une forme d'exécution préférentielle mais non limitative, la machine suivant l'invention comprend deux longerons à savoir un premier longeron 8a et un second longeron 8b. Les deux longerons 8a, 8b sont semblables, parallèles entre eux, placés côte à côte, disposés notamment horizontalement, rigides. Les deux longerons 8a, 8b sont guidés à coulissement axial le long d'un axe 9, notamment horizontal et transversal à l'axe 2, sur une même course de coulissement, par des moyens de coulissement 10. Les deux longerons 8a, 8b, sont entraînés en translation axiale le long de l'axe 9 et sur la course de coulissement, alternativement dans un sens et dans le sens opposé par des moyens d'entrai- nement 11.In a preferred but non-limiting embodiment, the machine according to the invention comprises two beams, namely a first beam 8a and a second beam 8b. The two beams 8a, 8b are similar, mutually parallel, placed side by side, arranged in particular horizontally, rigid. The two longitudinal members 8a, 8b are guided in axial sliding along an axis 9, in particular horizontal and transverse to the axis 2, on the same sliding stroke, by sliding means 10. The two longitudinal members 8a, 8b, are driven in axial translation along the axis 9 and on the sliding stroke, alternately in one direction and in the opposite direction by drive means 11.

Les deux longerons 8a, 8b sont associés fonctionnellement l'un à l'autre notamment mais non exclusivement par les moyens d'entraînement 11, pour être déplacés dans deux sens opposés. Par conséquent, lorsque l'un des longerons soit par exemple le longeron 8a se trouve à l'extrémité amont de la course de coulissement, l'autre longeron soit 8b se trouve à l'extrémité aval de la course. Inversement, lorsque le longeron 8a est à l'extrémité aval de la course de coulissement, le longeron 8b en est à l'extrémité amont.The two beams 8a, 8b are functionally associated with each other in particular but not exclusively by the drive means 11, to be moved in two opposite directions. Consequently, when one of the side members, for example the side member 8a, is at the upstream end of the sliding stroke, the other member, either 8b, is located at the downstream end of the stroke. Conversely, when the spar 8a is at the downstream end of the sliding stroke, the spar 8b is at the upstream end.

Chacun des longerons - notamment sa face horizontale supérieure 12 - peut éventuellement constituer respectivement dans sa partie amont 13 et dans sa partie aval 14 des moyens d'appui 15 une forme F ou d'un contenant C.Each of the side members - in particular its upper horizontal face 12 - may possibly constitute respectively in its upstream part 13 and in its downstream part 14 of the support means 15 a form F or of a container C.

Les moyens de saisie et de maintien 6 sont en deux ensembles 6a, 6b placés et associés aux deux parties extrêmes libres aval 16 des longerons respectifs 8a, 8b.The gripping and holding means 6 are in two sets 6a, 6b placed and associated with the two free downstream end portions 16 of the respective side members 8a, 8b.

De même, les moyens d'amenée 3 sont en deux ensembles 3a, 3b placés et associés aux parties extrêmes libres amont 17 des deux longerons respectifs 8a, 8b.Similarly, the supply means 3 are in two assemblies 3a, 3b placed and associated with the upstream free end portions 17 of the two respective longitudinal members 8a, 8b.

La machine comporte également un bâti non représenté supportant deux longerons latéraux 18 fixes, parallèles aux longerons 8a, 8b, écartés transversalement de ceux-ci, s'étendant le long de la machine notamment sur toute la course de coulissement des longerons 8a, 8b, dont la face supérieure horizontale est coplanaire aux faces 12, dont l'écartement est préférentiellement réglable, qui constituent en combinaison éventuellement avec les faces 12 des zones d'appui et de glissement des formes F ou contenant C.The machine also comprises a frame, not shown, supporting two fixed lateral beams 18, parallel to the beams 8a, 8b, spaced transversely from the latter, extending along the machine in particular over the entire sliding travel of the beams 8a, 8b, the horizontal upper face of which is coplanar with the faces 12, the spacing of which is preferably adjustable, which constitute, possibly in combination with the faces 12, support and sliding zones of the forms F or containing C.

Les moyens de réglage de la distance entre les deux longerons latéraux 18 peuvent faire l'objet de nombreuses variantes d'exécution à la portée de l'homme de métier. Alternativement, ces longerons 18 ne sont pas réglables mais d'une largeur telle qu'ils permettent le support de forme de dimensions variables. Alternativement également, il est prévu plusieurs couples de longerons 18 à des écartements différents.The means for adjusting the distance between the two side rails 18 can be the subject of numerous alternative embodiments within the reach of those skilled in the art. Alternatively, these beams 18 are not adjustable but of a width such that they allow the shape support of variable dimensions. Alternatively also, several pairs of beams 18 are provided at different spacings.

Les moyens de stockage 1 sont associés rigidement au bâti de la machine donc fixes, placés à la partie extrême amont de la machine et immédiatement au-dessus des longerons 8a, 8b et 18. Ces moyens de stockage peuvent éventuellement être réglables ou amovibles. Dans une forme d'exécution possible, mais non limitative, ils sont constitués par quatre cornières 19, placées verticalement défbissant le cadre dans lequel les formes peuvent être empilées. Ces cornières 19 sont notamment associées aux longerons latéraux 18. Les deux cornières amont 19a s'étendent jusqu'à la partie extrême libre inférieure des moyens de stockage 1 en constituant un blocage amont pour les formes F stockées. Les deux cornières aval 19b sont écartées de la face horizontale supérieure des longerons latéraux 18 et de la face horizontale supérieure 12, c'est-à-dire du plan P de glissement et translation des formes F d'une distance au moins égale à l'épaisseur d'une forme F, mais au plus égale à l'épaisseur de deux formes, de manière à permettre l'extraction d'une forme à la fois, par l'extrémité inférieure des moyens de stockage 1. Il est à observer que les formes F viennent se placer normalement au droit de l'ouverture ainsi constituée des moyens de stockage 1, par pesanteur et par l'appui réalisé sur la forme inférieure par les formes placées au-dessus.The storage means 1 are rigidly associated with the frame of the machine, therefore fixed, placed at the extreme upstream part of the machine and immediately above the side members 8a, 8b and 18. These storage means can optionally be adjustable or removable. In a possible, but non-limiting, embodiment, they are constituted by four angles 19, placed vertically defining the frame in which the shapes can be stacked. These angles 19 are in particular associated with the side rails 18. The two upstream angles 19a extend to the lower free end portion of the storage means 1 by constituting an upstream blocking for the stored forms F. The two downstream angles 19b are spaced from the upper horizontal face of the lateral beams 18 and from the upper horizontal face 12, that is to say from the plane P of sliding and translation of the forms F by a distance at least equal to l thickness of a form F, but at most equal to the thickness of two forms, so as to allow the extraction of one form at a time, by the lower end of the storage means 1. It should be observed that the forms F come to be placed normally at the level of the opening thus constituted by the storage means 1, by gravity and by the support produced on the lower form by the forms placed above.

Les moyens 6 de coulissement comprennent un longeron médian 20, d'axe 9, sétendant entre les deux longerons 8a, 8b,dont la face horizontale supérieure est coplanaire de la face 12, le longeron 20 est fixe et porté par le bâti de la machine. Le longeron médian 20 peut recevoir deux rails 21 avec lesquels coopèrent des roulements 22 d'axes horizontaux et transversaux portéspar les longerons 8a, 8b. En outre, les moyens de coulissement 10 comportent des galets 23 portés par le bâti de la machine, d'axe vertical, notamment, avec lesquels coopèrent des crémaillères 24, faisant partie des moyens d'entraînement 11, associés aux deux longerons 8a, 8b à leurs parties inférieures, dont les dentures sont internes et coopèrent avec un pignon denté 25 d'axe vertical porté par un arbre 26 entraîné à rotation dans un sens ou le sens opposé par un motovariateur d'entraînement à deux sens de rotation (figures 5 et 6).The sliding means 6 comprise a median beam 20, of axis 9, extending between the two beams 8a, 8b, the upper horizontal face of which is coplanar with the face 12, the beam 20 is fixed and carried by the frame of the machine . The central spar 20 can receive two rails 21 with which the bearings 22 of horizontal and transverse axes carried by the spars 8a, 8b cooperate. In addition, the sliding means 10 comprise rollers 23 carried by the frame of the machine, of vertical axis, in particular, with which the racks 24 cooperate, forming part of the drive means 11, associated with the two longitudinal members 8a, 8b at their lower parts, the teeth of which are internal and cooperate with a toothed pinion 25 of vertical axis carried by a shaft 26 driven in rotation in one direction or the opposite direction by a drive variable speed drive with two directions of rotation (FIGS. 5 and 6).

Chaque ensemble 3a, 3b des moyens d'amenée 3 se présente préfêrentiellement sous la forme d'un doigt constituant un cliquet (figure 8) c'est-à-dire comportant une face de blocage 27, verticale et une rampe inclinée 28. Ce doigt est mobile et soumis à l'action d'un ressort ou équivalent (non figuré) qui le sollicite vers sa position active tout en lui permettant d'être effacé notamment de passer sous la forme inférieure se trouvant dans les moyens de stockage 1 dans le sens aval - amont. Ce doigt est préférentiellement porté par une pièce 29 comportant un filetage avec lequel coopère une tige fileté 30 montée axialement dans chaque longeron 8a, 8b et porté par deux paliers d'extrémité 31 par rapport auxquels elle est à rotation libre. La tige filetée 30 saille du palier d'extrémité 31 donc du longeron 8a, "8b, la partie saillante comportant un moyen de préhension tel qu'uncarré ou similaire permettant de manoeuvrer à pivotement la tige filetée 30 et de régler la position longitudinale de la pièce 29 donc du doigt. Ce dispositif est tel que la tige filetée 30 peut être de grande longueur ce qui donne une grande possibilité de réglage de la position des moyens d'amenée 3. Naturellement, les longerons 8a, 8b sont pourvus de lumières 32, allongées, percées dans la partie amont 13 et permettant le passage des ensembles 3.Each set 3a, 3b of the supply means 3 is preferably in the form of a finger constituting a pawl (FIG. 8), that is to say comprising a blocking face 27, vertical and an inclined ramp 28. This finger is mobile and subjected to the action of a spring or equivalent (not shown) which urges it towards its active position while allowing it to be erased in particular to pass into the lower form located in the storage means 1 in the downstream - upstream direction. This finger is preferably carried by a part 29 comprising a thread with which a threaded rod 30 cooperates axially mounted in each spar 8a, 8b and carried by two bearings of ex end 31 with respect to which it is freely rotating. The threaded rod 30 protrudes from the end bearing 31 therefore of the spar 8a, "8b, the projecting part comprising a gripping means such as a square or the like enabling the threaded rod 30 to be pivoted and adjust the longitudinal position of the part 29 therefore of the finger This device is such that the threaded rod 30 can be very long which gives a great possibility of adjusting the position of the supply means 3. Naturally, the side members 8a, 8b are provided with lights 32 , elongated, drilled in the upstream part 13 and allowing the passage of the assemblies 3.

Chaque ensemble 6a, 6b des moyens de saisie comporte deux sous-ensembles soit 6la et 6"a pour l'ensemble 6a, 6'b et 6"b pour l'ensemble 6b. Les sous ensembles 6'a et 6'b d'une part, 6"a et 6"b d'autre part sont semblables et un seul d'entre eux sera décrit et désigné par 6' et 6".Each set 6a, 6b of the gripping means comprises two sub-assemblies, namely 6la and 6 "a for the set 6a, 6'b and 6" b for the set 6b. The subassemblies 6'a and 6'b on the one hand, 6 "a and 6" b on the other hand are similar and only one of them will be described and designated by 6 'and 6 ".

Le sous ensemble 6' est destiné à saisir la face fl'i qui reste normalement horizontale. Le sous ensemble 6' est donc placé horizontalement et se présente par exemple sous la forme d'au moins une - et généralement plusieurs - ventouses de succions 33 portées par un support 34 associé rigidement au longeron correspondant 8a, 8b la face de succion de la ventouse 33, notamment supérieure étant coplanaire du plan P. Naturellement, des moyens d'aspiration connus en soi sont associés à la ventouse 33.The sub-assembly 6 'is intended to grip the face fl'i which normally remains horizontal. The sub-assembly 6 ′ is therefore placed horizontally and is for example in the form of at least one - and generally several - suction cups 33 carried by a support 34 rigidly associated with the corresponding spar 8a, 8b the suction face of the suction cup 33, in particular upper being coplanar with plane P. Naturally, suction means known per se are associated with suction cup 33.

Le sous ensemble 6" est destiné à être associé à la face fl"s qui est soit horizontale dans le cas de la forme F (figure la), soit verticale dans le cas de-la forme dépliée FD ou du contenant C (figure lb et 1c). Le sous ensemble 6" comporte donc au moins une ventouse et générale--ment plusieurs ventouses de succions 35 portées par un support 36 mobile, associé directement ou non au longeron correspondant 8a, 8b.The sub-assembly 6 "is intended to be associated with the face fl" s which is either horizontal in the case of the form F (figure la), or vertical in the case of the unfolded form FD or of the container C (figure lb and 1c). The subassembly 6 "therefore comprises at least one suction cup and generally several suction cups 35 carried by a movable support 36, associated directly or not with the corresponding spar 8a, 8b.

Les ventouse 33, 35 sont associées à un dispositif d'aspiration connu en soi et non représenté, comportant des moyens de commande appropriés à la portée de l'homme de métier.The suction cups 33, 35 are associated with a suction device known per se and not shown, comprising control means suitable for those skilled in the art.

Les moyens 7 sont associés au support 36 et permettent le déplacement de celui-ci donc de la ventouse 35.The means 7 are associated with the support 36 and allow the displacement of the latter therefore of the suction cup 35.

Suivant l'invention, la ventouse 35 peut se trouver dans trois positions particulières :

  • Dans une première position illustrée par la figure 9a, la ventouse 35 est totalement escamotée c'est-à-dire qu'elle se trouve en dessous du plan P ce qui ne gêne pas par conséquent le passage au-dessus d'elle d'un contenant C. Dans une deuxième position illustrée par la figure 9b, la ventouse 35 se trouve placée horizontalement notamment au droit d'une ventouse 33 (figure 9b). Cette position permet aux ensembles de ventouses 33,35 de saisir les deux faces de travail ft d'une forme pliée F.
According to the invention, the suction cup 35 can be in three particular positions:
  • In a first position illustrated by FIG. 9a, the suction cup 35 is completely retracted, that is to say that it is located below the plane P, which does not therefore hamper the passage above it of a container C. In a second position illustrated by FIG. 9b, the suction cup 35 is placed horizontally in particular in line with a suction cup 33 (FIG. 9b). This position allows the sets of suction cups 33,35 to grip the two working faces ft of a folded form F.

Dans la troisième position, la ventouse 35 est placée verticalement, donc perpendiculairement à l'avant de la ventouse 33 (figure 9c). Cette disposition permet d'amener et de maintenir les deux faces de travail ft à équerre c'est-à-dire de déplier la forme F. Chronologiquement, et en supposant qu'une forme soit prête à être dépliée, la ventouse 35 se trouve dans sa seconde position illustrée par la figure 9b, puis passe dans la troisième position illustrée par la figure 9c où la forme F est dépliée, puis enfin passe dans sa première position illustrée par la figure 9a qui permet l'évacuation du contenant C. On peut concevoir de nombreuses variantes d'exécution en ce qui concerne la position escamotée des ventouses mobiles 35, donc les moyens d'entraînement 7.In the third position, the suction cup 35 is placed vertically, therefore perpendicular to the front of the suction cup 33 (Figure 9c). This arrangement makes it possible to bring and maintain the two working faces ft at an angle, that is to say to unfold the form F. Chronologically, and assuming that a form is ready to be unfolded, the suction cup 35 is found in its second position illustrated by FIG. 9b, then passes into the third position illustrated by FIG. 9c where the form F is unfolded, then finally passes into its first position illustrated by FIG. 9a which allows the evacuation of the container C. On can conceive of numerous variant embodiments with regard to the retracted position of the movable suction cups 35, therefore the drive means 7.

Dans la forme d'exécution illustrée par la figure 9a, les ventouses 35 sont, dans la position escamotée placées verticalement en dessous du plan P. Dans la forme d'exécution illustrée par la figure 10c, la ventouse 35 est placé horizontalement dans le prolongement de la ventouse 33. Dans le cas de la figure 11c, la ventouse 35 est en position escamotée inclinée.In the embodiment illustrated in FIG. 9a, the suction cups 35 are, in the retracted position placed vertically below the plane P. In the embodiment illustrated by FIG. 10c, the suction cup 35 is placed horizontally in the extension of the suction cup 33. In the case of FIG. 11c, the suction cup 35 is in the inclined retracted position.

Dans le cas des figures 9a, 9b, 9c , les moyens 7 sont conçus pour permettre la combinaison d'un pivotement à 90° puis d'une translation verticale de la ventouse 35. Dans le cas des figures 10a, lOb, 10c, les moyens 7 sont conçus pour permettre un pivotement de la ventouse 35 de 180°. Dans le cas des figures lla, llb, llc, les moyens 7 sont conçus pour permettre un double pivotement des moyens 35 d'une part de 90° et d'autre part de l'ordre d'au moins 30 à 45°.In the case of FIGS. 9a, 9b, 9c, the means 7 are designed to allow the combination of a 90 ° pivoting then of a vertical translation of the suction cup 35. In the case of FIGS. 10a, 10b, 10c, the means 7 are designed to allow pivoting of the suction cup 35 by 180 °. In the case of FIGS. 11a, 11b, 11c, the means 7 are designed to allow a double pivoting of the means 35 on the one hand by 90 ° and on the other hand of the order of at least 30 to 45 °.

Dans le cas particulier des figures 9a, 9b, 9c, les moyens 7 se présentent sous la forme suivante: le support 36 est monté articulé autour de l'axe 2 sur une console 37 montée à coulissement vertical, notamment sur une partie externe libre aval notamment sur la partie extrême libre aval 16 du longeron 8a, 8b. Cette console 37 est associée à la tige 38 d'un vérin 39 porté par le longeron 8a, 8b. Ce vérin 39 permet d'élever et d'abaisser la console 37 donc de faire passer les ventouses 35 de la première à la troisième position ou inversement. Un second vérin 40 est porté par la console 37 et sa tige 41 est associée au support 36, en formant levier. Le vérin 40 permet le pivotement du support 36 donc des ventouses 35 autour de l'axe 2.In the particular case of FIGS. 9a, 9b, 9c, the means 7 are in the following form: the support 36 is mounted articulated around the axis 2 on a console 37 mounted with vertical sliding, in particular on a free downstream external part in particular on the downstream free end portion 16 of the beam 8a, 8b. This console 37 is associated with the rod 38 of a jack 39 carried by the beam 8a, 8b. This jack 39 makes it possible to raise and lower the console 37 therefore to move the suction cups 35 from the first to the third position or vice versa. A second cylinder 40 is carried by the console 37 and its rod 41 is associated with the support 36, forming a lever. The jack 40 allows the support 36 to pivot, therefore the suction cups 35 around the axis 2.

Comme on l'a bien compris, les ventouses 33, 35, c'est-à-dire les sous ensembles 6'a ; 6"a, d'une part 6'b, 6"b d'autre part constituent une pince de succion permettant de déplier et de maintenir dépliée une forme initialement pliée.As is well understood, the suction cups 33, 35, that is to say the subassemblies 6'a; 6 "a, on the one hand 6'b, 6" b on the other hand constitute a suction forceps making it possible to unfold and maintain unfolded an initially folded shape.

La machine qui vient d'être décrite fonctionne selon les phases du procédé décrit précédemment ; les moyens de stockage 1 sont chargés de forme F pliées. Les moyens d'entraînement 11 sont mis en oeuvre. Tout d'abord, l'un des ensembles des moyens d'amenée, soit par exemple l'ensemble 3a associé au longeron 8a vient interférer avec l'arête amont am de la forme inférieure des moyens de stockage. Le doigt 8a est déplacé d'amont en aval et entraîne la forme F. Le mouvement de coulissement se poursuit jusqu'à ce que l'arête aval av de la forme vienne correspondre à l'axe 2 des moyens de saisie 6 associés à l'autre longeron soit 8b, donc à l'ensemble 6b, les deux sous ensembles 6'b et 6"b se trouvant alors dans la troisième position illustrée par la figure 9c. A cette fin, il est procédé à un réglage de la distance entre les ensembles de moyens d'amenée 3 et les ensembles de moyens de saisie 6 pour que dans la position décrite, leur écartement corresponde à la distance entre les arêtes amont am et aval av de la forme pliée. Les moyens de saisie 6 et les moyens 7 sont alors actionnés pour venir saisir comme indiqué précédemment les deux faces de travail de la forme puis déployer celle-ci jusqu'à amener ces deux faces perpendiculairement l'une à l'autre.The machine which has just been described operates according to the phases of the process described above; the storage means 1 are loaded with folded form F. The drive means 11 are used. First of all, one of the sets of supply means, for example the set 3a associated with the spar 8a, comes to interfere with the upstream edge am of the lower shape of the storage means. The finger 8a is moved from upstream to downstream and drives the form F. The sliding movement continues until the downstream edge av of the shape comes to correspond to the axis 2 of the gripping means 6 associated with the 'other spar is 8b, therefore to the assembly 6b, the two subassemblies 6'b and 6 "b then being in the third position illustrated in FIG. 9c. To this end, the distance is adjusted between the sets of feeding means 3 and the sets of gripping means 6 so that, in the position described, their spacing corresponds to the distance between the upstream edges am and downstream av of the folded form. means 7 are then actuated to come and grasp, as indicated above, the two working faces of the form and then deploy the latter until the two faces are brought perpendicular to one another.

Ensuite, le mouvement du longeron 8a peut se poursuivre vers l'aval pour permettre la finition du contenant. La machine comporte à cet égard des moyens de finition permettant la fermeture des rabats du couvercle, leur encollage, le pressage etc.Then, the movement of the beam 8a can continue downstream to allow the container to be finished. In this respect, the machine includes finishing means allowing the closing of the lid flaps, their gluing, pressing, etc.

Simultanément au mouvement du premier longeron 8a, le longeron 8b s'est déplacé d'aval en amont. La rampe 28 des moyens d'amenée 3 est venue interférer avec la forme inférieure des moyens de stockage 1 et le doigt s'effacer en permettant aux moyens d'amenée 3b de venir se placer dans la position à partir de laquelle une forme peut être extraite des moyens de stockage 1.Simultaneously with the movement of the first spar 8a, the spar 8b has moved from downstream to upstream. The ramp 28 of the feeding means 3 has come to interfere with the lower shape of the storage means 1 and the finger is erased by allowing the feeding means 3b to come to be placed in the position from which a shape can be extracted from the storage means 1.

Naturellement, l'invention peut faire l'objet de nombreuses autres variantes d'exécution.Naturally, the invention can be the subject of numerous other alternative embodiments.
