Description

Traditionnellement, les emballages stockables à plat en matière synthétique, rigide ou semi rigide, imprimé ou non, sont réalisés à partir de flans découpés, par une succession de phases s'effectuant à des postes indépendants et comprenant, une éventuelle décoration du flan, le marquage de ses plis et le découpage respectivement de sa périphérie, des trous intérieurs et de certaines parties dites critiques, telles que les zones d'angles rentrants. Cette façon de procéder nécessite de nombreuses manipulations, exige donc de la main d'oeuvre mais aussi des espaces pour les stockages intermédiaires entre postes. De plus, après découpage, la séparation de l'emballage à plat et de ses déchets, exige une intervention manuelle dite de décorticage pour éliminer les déchets non éliminés hors du découpage.Traditionally, packaging that can be stored flat in synthetic, rigid or semi-rigid material, printed or not, is produced from cut blanks, by a succession of phases carried out at independent stations and comprising, if necessary, decoration of the blank, the marking of its folds and the cutting respectively of its periphery, the interior holes and certain so-called critical parts, such as the areas of re-entrant angles. This way of proceeding requires many manipulations, therefore requires manpower but also spaces for intermediate storage between stations. In addition, after cutting, the separation of the flat packaging and its waste requires manual intervention called shelling to remove the non-eliminated waste from cutting.

Il en est par exemple ainsi avec l'installation décrite dans DEA-3617916 où l'emballage et le déchet de film sont éjectés ensemble par un tapis roulant.This is for example the case with the installation described in DEA-3617916 where the packaging and the film waste are ejected together by a conveyor belt.

La présente invention a pour but de remédier à ces inconvénients en fournissant une installation de fabrication entièrement automatique, c'est à dire n'exigeant aucune intervention humaine, délivrant des piles d'emballages à plat, tout en supprimant tout stockage intermédiaire entre les postes et pouvant fonctionner avec des alimentations en flan différentes.The present invention aims to remedy these drawbacks by providing a fully automatic manufacturing installation, that is to say requiring no human intervention, delivering stacks of flat packaging, while eliminating any intermediate storage between stations. and able to operate with different blank power supplies.

Cette installation est du type comprenant une table de marge positionnant chaque flan en amont d'un poste de travail, un plateau formant chemin de transfert principal et coopérant avec des moyens de déplacement pas à pas de chaque flan à partir de la table de marge jusqu'au poste le plus aval d'éjection du flan, et d'amont en aval de ce chemin de transfert, un poste de marquage à chaud des plis, au moins un poste de découpage, à froid ou à chaud de l'emballage dans le flan et de poinçonnage du flan, et un tapis roulant transversal d'évacuation des produits découpés.This installation is of the type comprising a margin table positioning each blank upstream of a work station, a plate forming the main transfer path and cooperating with means for moving step by step each blank from the margin table up to '' at the most downstream ejection station of the blank, and upstream downstream of this transfer path, a station for hot marking of the plies, at least one cutting station, cold or hot of the packaging in the blank and punching the blank, and a transverse conveyor belt for discharging the cut products.

Selon l'invention, le poste de découpage est suivi d'un premier poste de décorticage des déchets de poinçonnage des perforations disposées à l'intérieur de la périphérie de l'emballage, poste faisant tomber les déchets dans un bac disposé sous le plateau,et d'un second poste de décorticage assurant le détourage de l'emballage à plat et sa séparation du flan, en faisant tomber chaque emballage à plat sur le tapis roulant transversal à fonctionnement pas à pas, l'amenant à une zone d'attente, tandis que le poste de décorticage est suivi d'un poste d'éjection dans un bac du déchet formé par la ceinture du flan, et que, d'autre part, la zone d'attente est disposée à l'une des extrémités de la trajectoire de moyens automatiques de reprise de chacun des emballages à plat faisant partie d'un poste d'empilage.According to the invention, the cutting station is followed by a first shelling station for punching waste from the perforations arranged inside the periphery of the packaging, station dropping the waste in a bin disposed under the tray, and a second shelling station ensuring the trimming of the flat packaging and its separation from the blank, by dropping each packaging flat on the transverse conveyor belt in operation step by step, bringing it to a waiting area, while the shelling station is followed by an ejection station in a waste bin formed by the blank belt, and that, on the other hand, the waiting area is arranged at one end of the trajectory of automatic recovery means for each of the flat packages forming part of a stacking station.

Ainsi, dès qu'il est positionné à la table de marge, chaque flan est saisi par les moyens de préhension, est déplacé pas à pas surle plateau du chemin de transfert où, successivement, ses plis sont marqués à chaud, puis il est découpé et poinçonné pour former l'emballage à plat. Ces deux opérations sont suivies d'un décorticage visant à séparer l'emballage à plat des déchets des perforations et des zones critiques, mais aussi de sa découpe périphérique. Suivant une caractéristique originale de l'invention, ce décorticage est effectué en deux fois et à deux postes distincts. Le premier concerne les déchets et découpes situés à l'intérieur du périmètre de l'emballage, et le second, la seule découpe périphérique; c'est à dire le déchet du flan. Au premier poste de décorticage, les déchets traversent le plateau fixe du chemin de transfert pour rejoindre un bac à déchets alors qu'au second poste, c'est l'emballage à plat qui traverse le plateau pour rejoindre un autre poste, tandis que sa découpe périphérique reste sur le plateau fixe pour être amenée, par les moyens de déplacement, à un poste d'éjection vers un bac à déchets.Thus, as soon as it is positioned at the margin table, each blank is gripped by the gripping means, is moved step by step on the tray of the transfer path where, successively, its folds are hot stamped, then it is cut out and punched to form the flat packaging. These two operations are followed by a peeling aimed at separating the flat packaging of the waste from the perforations and critical areas, but also from its peripheral cutting. According to an original characteristic of the invention, this shelling is carried out in two stages and at two separate stations. The first concerns the waste and cuts located inside the perimeter of the packaging, and the second, the only peripheral cutting; that is to say the waste of the blank. At the first shelling station, the waste crosses the fixed tray of the transfer path to reach a waste bin while in the second station, it is the flat packaging which crosses the tray to reach another station, while its peripheral cutting remains on the fixed plate to be brought, by the displacement means, to an ejection station towards a waste bin.

Cette division des postes et leur aménagement permettent d'obtenir un parfait décorticage, sans besoin d'aucune reprise manuelle, donc sans intervention humaine.This division of the stations and their layout make it possible to obtain perfect shelling, without the need for any manual rework, therefore without human intervention.

Dans une forme d'exécution de l'invention, et en particulier lorsque l'emballage a besoin d'une décoration, en complément ou en remplacement d'une pré-impression, un poste d'impression de chaque flan est intercalé entre la table de marge et le poste de marquage des plis à chaud.In one embodiment of the invention, and in particular when the packaging needs decoration, in addition to or instead of a pre-printing, a printing station for each blank is inserted between the table margin and hot pleat marking station.

Dans la forme d'exécution représentée, l'installation comprend, en amont d'un plateau horizontal 2 formant chemin de transfert principal, des moyens d'alimentation A en flan 3 et, successivement le long de ce chemin de transfert, respectivement, un poste B de décoration, un poste C de marquage, à chaud et par haute fréquence des plis, un poste D de découpe du flan au moyen d'un poinçon ou emporte-pièce chauffant, un premier poste E de décorticage, un second poste F de décorticage, et enfin un poste G d'éjection des déchets.In the embodiment shown, the installation comprises, upstream of a horizontal plate 2 forming the main transfer path, supply means A in the blank 3 and, successively along this transfer path, respectively, a station B for decoration, a station C for marking, hot and by high frequency of the folds, a station D for cutting the blank by means of a heating punch or punch, a first station E for shelling, a second station F shelling, and finally a G waste ejection station.

Le poste d'alimentation A est composé d'une table de marge 4 assurant le positionnement de chacun des flans 3 qui lui sont amenés par un automate de transfert 5 avec plateau à ventouses 6, soit d'un magasin de stockage 7 d'une pile de flans, soit de la zone de sortie d'un ensemble H de découpage des flans. Cet ensemble comprend un porte bobine 8, un dérouleur batteur 9 et un poste 10 de découpage d'un flan dans la bande se dévidant de la bobine. Il est monté sur rail pour dégager l'installation lorsqu'il n'est pas utilisé.The feeding station A is composed of a margin table 4 ensuring the positioning of each of the blanks 3 which are brought to it by a transfer automaton 5 with suction cup plate 6, that is to say of a storage magazine 7 of a stack of blanks, that is to say from the exit zone of a set H for cutting blanks. This assembly includes a reel holder 8, a beater unwinder 9 and a station 10 for cutting a blank in the strip unwinding from the reel. It is mounted on a rail to free the installation when it is not in use.

Le plateau 2 du chemin de transfert est associé à des moyens de préhension et de déplacement pas à pas de chacun des flans 3 amenés à la table de marge 4, moyens qui, dans la forme d'exécution représentée, sont constitués par des pinces transversales 12 espacées longitudinalement d'un pas et reliées chacune à deux chaines 13, décrivant une trajectoire continue sous le plateau 2. La liaison entre les pinces et les chaines est assurée par des doigts, non représentés, circulant dans des glissières ménagées dans la table 2. Bien entendu, les chaines sont reliées à des moyens moteurs aptes à leur communiquer un mouvement de translation pas à pas permettant d'amener chaque flan à chacun des postes successifs.The plate 2 of the transfer path is associated with means for gripping and moving step by step of each of the blanks 3 brought to the margin table 4, means which, in the embodiment shown, consist of transverse clamps 12 spaced longitudinally with one step and each connected to two chains 13, describing a continuous trajectory under the plate 2. The connection between the clamps and the chains is ensured by fingers, not shown, circulating in slides arranged in the table 2. Good understood, the chains are connected to motor means capable of communicating to them a translational movement step by step allowing each blank to be brought to each of the successive stations.

Les différents postes de travail B à F précédemment décrits comprennent chacun une presse 15, de type mécanique ou hydraulique comme représenté aux figures 1 et 2. Dans chacune de ces presses, le plateau supérieur mobile 16 porte l'outil assurant l'opération au poste considéré, tandis que le plateau inférieur est constitué par le plateau 2.The various work stations B to F previously described each include a press 15, of mechanical or hydraulic type as shown in Figures 1 and 2. In each of these presses, the movable upper plate 16 carries the tool ensuring the operation at the station considered, while the lower plate is constituted by plate 2.

Au poste de décoration B, le plateau supérieur 16 comporte des moyens 14 pour assurer la décoration, par tempographie ou marquage à chaud, en complément ou en remplacement d'une pré-impression.At decoration station B, the upper plate 16 includes means 14 for decoration, by tempography or hot stamping, in addition to or in replacement of a pre-printing.

Au poste de marquage C, le plateau mobile supérieur 16 de la presse est muni d'un poinçon amovible 17 apte à réaliser, dans le flan placé sous lui, des plis de marquage et par exemple ceux représentés en 18 à la figure 3. En pratique, le poinçon 17 est relié à un générateur à haute fréquence 19 disposé latéralement au chemin de transfert 2.At the marking station C, the upper movable plate 16 of the press is provided with a removable punch 17 capable of producing, in the blank placed under it, marking folds and for example those shown at 18 in FIG. 3. In in practice, the punch 17 is connected to a high frequency generator 19 disposed laterally to the transfer path 2.

Au poste D, le plateau supérieur mobile 16 de la presse verticale 15 est muni d'un poinçon amovible chauffant 39 apte à réaliser dans le flan, des perforations 20, des lignes de séparation 21 et la trace périphérique 22 délimitant l'emballage dans le flan 3, comme montré à la figure 3.At station D, the movable upper plate 16 of the vertical press 15 is provided with a removable heating punch 39 capable of producing in the blank, perforations 20, separation lines 21 and the peripheral trace 22 delimiting the packaging in the blank 3, as shown in Figure 3.

Au premier poste de décorticage E, le plateau mobile supérieur 16 est muni de poinçons amovibles 23, aptes à chasser les déchets de poinçonnage des perforations 20 et 21 à travers des ouvertures, non représentées, du plateau 2. Ces déchets passent à travers le plateau 2 et tombent dans un bac à déchets 34 (visible figure 3).At the first shelling station E, the upper movable plate 16 is provided with removable punches 23, capable of expelling the punching waste from the perforations 20 and 21 through openings, not shown, of the plate 2. This waste passes through the plate 2 and fall into a waste container 34 (visible in FIG. 3).

Le second poste de décorticage F est similaire au premier, à la différence que le plateau supérieur mobile 16 comporte un poinçon amovible 24 dont le contour correspond à celui extérieur de l'emballage à plat que l'on veut réaliser. Comme le montre plus en détails les figures 4 et 5, ce poinçon 24 est destiné à passer à travers une ouverture 25, de même forme que lui et ménagée dans le plateau fixe 2. Il est associé à des serre-flans 26 composés de deux éléments télécospiques incluant un ressort de rappel 27. Ainsi, lorsque le plateau mobile 16 de la presse est déplacé verticalement vers le bas dans le sens de la flèche 28 de figure 4, les serre-flans viennent prendre appui sur le flan 3 pour le plaquer sur le plateau fixe 2 avant que le poinçon 24 ne vienne en contact avec l'emballage à plat. Ainsi, lorsque ce poinçon rencontre l'emballage 29, ceinturé par la ligne de découpe 22, pour le désolidariser du flan 3 en le faisant passer à travers l'ouverture 25, ledit flan est parfaitement maintenu et ne peut pas glisser, en gênant le décorticage de l'emballage. Il est à noter que les poinçons 23 du premier poste de décorticage peuvent aussi être associés à des serres-flans du type décrit ci dessus.The second shelling station F is similar to the first, with the difference that the movable upper plate 16 comprises a removable punch 24 whose outline corresponds to that outside of the flat packaging you want to make. As shown in more detail in FIGS. 4 and 5, this punch 24 is intended to pass through an opening 25, of the same shape as it and formed in the fixed plate 2. It is associated with blank clamps 26 composed of two telecospheric elements including a return spring 27. Thus, when the movable plate 16 of the press is moved vertically downward in the direction of the arrow 28 in FIG. 4, the blank clamps come to bear on the blank 3 to press it down on the fixed plate 2 before the punch 24 comes into contact with the flat packaging. Thus, when this punch meets the packaging 29, surrounded by the cutting line 22, to separate it from the blank 3 by passing it through the opening 25, said blank is perfectly maintained and cannot slip, hampering the peeling the packaging. It should be noted that the punches 23 of the first shelling station can also be associated with greenhouses of the type described above.

La figure 5 montre que l'emballage à plat ainsi formé est chassé sur le brin supérieur d'un tapis sans fin 30 muni localement de perforations 32 communiquant avec un caisson d'aspiration 33, relié à une source de vide.FIG. 5 shows that the flat packaging thus formed is expelled on the upper strand of an endless belt 30 provided locally with perforations 32 communicating with a suction box 33, connected to a source of vacuum.

La ceinture 3a réalisée par découpage de l'emballage dans le flan 3 est, comme montrée à la figure 3, amenée dans une phase suivante au poste G d'éjection des déchets où elle est chassée dans un bac à déchets 31.The belt 3a produced by cutting the packaging from the blank 3 is, as shown in FIG. 3, brought in a next phase to the station G for ejecting the waste where it is removed into a waste bin 31.

Cette figure 3 montre que le tapis aspirant 30 est disposé transversalement au plateau 2 constituant chemin de transfert longitudinal, de manière à amener l'emballage à plat 29 à une zone d'attente désignée de façon générale par J. Le tapis 30 est relié à des moyens moteurs aptes à le déplacer de manière cyclique avec une course correspondant à l'intervalle entre le second poste de décorticage et la zone d'attente J.This FIG. 3 shows that the suction belt 30 is arranged transversely to the plate 2 constituting a longitudinal transfer path, so as to bring the packaging flat 29 to a waiting area generally designated by J. The belt 30 is connected to motor means able to move it cyclically with a stroke corresponding to the interval between the second shelling station and the waiting zone J.

Le recours à un tapis aspirant 30 est indispensable lorsque, comme montré figure 6, l'on réalise, simultanément dans un même flan et par un plateau comportant plusieurs poinçons 24, plusieurs emballages à plat 29a-29b, identiques ou différents, car, alors, il conserve la position relative des emballages à plat, entre le poste de décorticage et la zone d'attente et favorise ainsi l'empilage ultérieur, et la reprise éventuelle au poste de conditionnement et de remplissage final. En d'autres termes, le tapis 30 évite d'avoir à trier manuellement les emballages à plat obtenus et déversés dans un bac avec leurs déchets, comme c'est le cas dans les installations actuelles.The use of a suction mat 30 is essential when, as shown in FIG. 6, several flat packages 29a-29b, identical or different, are produced simultaneously in the same blank and by a plate comprising several punches 24, because then , it keeps the relative position of the flat packaging, between the hulling and waiting area and thus promotes subsequent stacking, and possible resumption at the packaging and final filling station. In other words, the belt 30 avoids having to manually sort the flat packages obtained and discharged into a bin with their waste, as is the case in current installations.

Comme le montre la figure 3, le poste d'empilage, désigné de façon générale par K, est disposé transversalement au tapis 30, c'est à dire parallèlement au chemin de transfert 2. Il est composé d'un tapis roulant 35 apte à se déplacer de façon cyclique dans le sens de la flèche 36 de cette figure 3. La longueur de ce tapis est suffisante pour qu'il possède une zone d'empilage proprement dite, référencée K1, et une zone K2 d'attente avant préhension de la pile pour stockage.As shown in Figure 3, the stacking station, generally designated by K, is arranged transversely to the belt 30, that is to say parallel to the transfer path 2. It is composed of a conveyor belt 35 capable of move cyclically in the direction of arrow 36 in this figure 3. The length of this mat is sufficient for it to have a proper stacking zone, referenced K1, and a waiting zone K2 before gripping the battery for storage.

Un automate de transfert 37, avec plateau à ventouses 38, est disposé au dessus des zones d'attente J et d'empilage K1, de manière à prélever sur le tapis aspirant 30 chacun des emballages 29 décortiqués pour l'amener sur la pile en cours de formation. Lorsque la pile a atteint un nombre d'éléments déterminé, elle est amenée au poste d'attente K2 par déplacement du tapis 35.A transfer machine 37, with suction cup plate 38, is arranged above the waiting zones J and stacking zones K1, so as to take from the suction belt 30 each of the packages 29 peeled to bring it onto the stack. training courses. When the stack has reached a determined number of elements, it is brought to the waiting station K2 by moving the belt 35.

Grâce à cette installation, chaque flan, préimprimé ou non, provenant soit du magasin 7, soit de l'ensemble de découpage H, est automatiquement amené sur la table de marge 4 pour subir, successivement et de manière entièrement automatique, les diverses opérations permettant de réaliser l'emballage à plat, son décorticage, sa séparation d'avec le déchet du flan et son empilage, tandis que, simultanément les différents déchets sont éliminés, et cela sans recours à aucune intervention manuelle.Thanks to this installation, each blank, preprinted or not, coming either from the magazine 7 or from the cutting assembly H, is automatically brought to the margin table 4 to undergo, successively and entirely automatically, the various operations allowing to carry out the packaging flat, its peeling, its separation from the waste of the blank and its stacking, while, simultaneously, the various wastes are eliminated, and this without recourse to any manual intervention.

Une telle installation peut être utilisée pour réaliser tout type d'emballage à plat, utilisable immédiatement ou nécessitant une reprise avant remplissage.Such an installation can be used to make any type of flat packaging, usable immediately or requiring recovery before filling.

Grâce à sa structure, cette installation réduit les temps morts entre les différents postes, supprime toute zone de stockage intermédiaire et améliore ainsi la productivité des emballages à plat.Thanks to its structure, this installation reduces downtime between the different stations, eliminates any intermediate storage area and thus improves the productivity of flat packaging.
