Description

L'invention se rapporte à un module porte-outils pour le façonnage d'au moins une découpe de carton, afin de réaliser un élément de conditionnement.The invention relates to a tool-holder module for shaping at least one cardboard blank to produce a packaging element.

Par « éléments de conditionnement », on devra comprendre des caisses de carton, des présentoirs se présentant sous la forme d'un plateau à bords rabattus, des coiffes de lots de produits, des caisses à couvercle présentant des rabats etc.The term "packaging elements" should be understood to include cardboard boxes, displays in the form of a tray with flanged edges, caps for batches of products, crates with lids having flaps, etc.

On connaît des procédés et des installations qui assurent le façonnage de découpes de cartons dans une installation industrielle pour réaliser de tels éléments de conditionnement. Ces derniers sont usuellement réalisés à des cadences pouvant atteindre 25 pièces par minutes.Processes and systems are known which process cardboard blanks in an industrial plant to make such packaging elements. These are usually made at rates of up to 25 pieces per minute.

Ainsi, par exemple, dans le domaine du façonnage d'éléments de conditionnement, ou d'emballages divers réalisés à partir de découpes de carton, on connaît des installations qui comportent un poste équipé d'une matrice et d'un poinçon, ces derniers étant disposés de part et d'autre d'un tapis d'amenée de découpes de carton. Les découpes sont amenées en regard de la matrice, et l'élément à façonner est réalisé par matriçage de la découpe, c'est-à-dire par application sous pression de la matrice sur un côté de la découpe de carton, le poinçon prenant appui contre l'autre côté de la découpe, en même temps. Le document DE 200 19 140 décrit par exemple une telle installation de façonnage.Thus, for example, in the field of forming packaging elements, or various packages made from cardboard blanks, there are known installations that include a station equipped with a die and a punch, the latter being arranged on either side of a conveyor belt for cardboard blanks. The cuts are brought opposite the die, and the element to be shaped is made by stamping the cut, that is to say by applying under pressure the die on one side of the cardboard blank, the punch taking support against the other side of the cut, at the same time. The document DE 200 19 140 describes for example such a processing plant.

A l'origine de l'invention, on a cherché à réaliser une installation qui permet d'atteindre des cadences plus élevées que celles des machines existantes. Autrement dit, on a cherché à atteindre des cadences supérieures à 25 pièces par minute.At the origin of the invention, we sought to achieve an installation that achieves higher rates than existing machines. In other words, we sought to achieve rates greater than 25 pieces per minute.

On a également cherché à réaliser une machine qui s'adapte au façonnage de divers éléments, par exemple au façonnage de plateaux présentoirs en carton, tout comme à la fermeture de caisses, par exemple.It has also been sought to produce a machine that adapts to the shaping of various elements, for example the shaping of cardboard display trays, as well as the closing of crates, for example.

L'invention atteint ces objectifs et concerne, dans un premier temps, un procédé de façonnage d'au moins une découpe de carton entre une position d'entrée et une position de sortie d'un poste de façonnage, le procédé comprenant une étape d'application d'outils de façonnage sur ladite découpe de carton, lesdits outils étant animés d'un mouvement de va-et-vient de part et d'autre de ladite découpe entre une position de façonnage et une position escamotée,The invention achieves these objectives and relates, in a first step, to a method of forming at least one carton blank between an input position and an output position of a forming station, the method comprising a step of applying forming tools to said cardboard blank, said tools being reciprocated on either side of said blank between a shaping position and a retracted position,

ledit procédé consistant à assurer le déplacement de la découpe de carton au moyen desdits outils de façonnage entre ladite position d'entrée et ladite position de sortie du poste de façonnage en même temps que la découpe de carton est façonnée par lesdits outils de façonnage. Un tel procédé est notamment décrit dans le document DE 198 43 490 .said method of moving the carton blank by means of said forming tools between said input position and said output position of the forming station at the same time as the carton blank is shaped by said forming tools. Such a method is described in particular in the document DE 198 43 490 .

Conformément à l'invention, le procédé est remarquable en ce que dans ledit poste de façonnage, il met en oeuvre au moins deux modules porte-outils, chaque module porte-outils comprenant au moins un chariot de façonnage portant une matrice et un poinçon constituant les outils de façonnage, chaque chariot de façonnage de chaque module prenant en charge à tour de rôle des découpes de carton arrivant en position d'entrée dudit poste de façonnage.According to the invention, the method is remarkable in that in said processing station, it implements at least two tool-holder modules, each tool-carrying module comprising at least one shaping carriage carrying a matrix and a punch constituting the shaping tools, each shaping carriage of each module taking care in turn of the cardboard blanks arriving in the input position of said shaping station.

Le fait que chaque chariot de façonnage comprend une matrice (entière - qui ne se présente pas en deux parties) et un poinçon offrent plusieurs avantages : la quantité de matériel mis en oeuvre est réduite (seulement deux modules) tout en assurant des cadences élevées. L'encombrement de la machine permettant de réaliser le procédé est aussi moins important que celui de la machine présentée dans le document DE 198 43 490 .The fact that each forming carriage comprises a matrix (whole - which is not in two parts) and a punch offer several advantages: the amount of material used is reduced (only two modules) while ensuring high rates. The size of the machine making it possible to carry out the process is also less important than that of the machine presented in the document DE 198 43 490 .

Le procédé selon l'invention comporte également les caractéristiques suivantes, prises séparément ou en combinaison :

  • la prise en charge des découpes à tour de rôle par les chariots de façonnage desdits au moins deux modules est réalisée à intervalles réguliers ;
  • le procédé comporte une étape d'application de colle sur au moins une partie d'une découpe de carton avant façonnage de la découpe de carton.
The method according to the invention also comprises the following characteristics, taken separately or in combination:
  • the support of the cuttings in turn by the forming carriages of said at least two modules is performed at regular intervals;
  • the method comprises a step of applying glue on at least a portion of a carton blank before forming the carton blank.

L'invention concerne également l'application du procédé, tel que défini ci-dessus pour la réalisation de présentoirs en carton, pour la réalisation de caisses en carton, pour la réalisation de lots d'articles. L'invention concerne encore l'application du procédé à la fermeture de caisses.The invention also relates to the application of the process, as defined above, for the production of cardboard displays for the production of crates in cardboard, for producing batches of articles. The invention further relates to the application of the method to the closure of boxes.

Par ailleurs, l'invention concerne un module porte-outils de façonnage d'au moins une découpe de carton dans un poste de façonnage, pour la mise en oeuvre du procédé tel que défini ci-dessus, le module porte-outil comportant :

  • au moins un jeu d'outils de façonnage ;
  • des moyens de déplacement de chacun des outils de part et d'autre d'une découpe de carton, entre une position de façonnage et une position escamotée ;
  • des moyens pour appliquer sous pression au moins un parmi les outils contre une face de la découpe.

Il va tout d'abord être fait référence aux figures 1a, 1b et 2 à 5 pour décrire une installation conforme à l'invention, comprenant un seul module 1 porte-outils de façonnage d'au moins une découpe 2 de carton dans un poste 3 de façonnage.It will first be referred to Figures 1a, 1b and 2 to 5 to describe an installation according to the invention, comprising a single module 1 tool holder for shaping at least one blank 2 cardboard in a station 3 shaping.

Dans la description qui va suivre, les termes « inférieur », « supérieur », « haut », « bas », « droite » et « gauche » sont utilisés en référence aux dessins pour une plus grande facilité de compréhension. Ils ne doivent pas être compris comme étant des limitations de la portée de l'invention, notamment quant à l'orientation du module 1 de façonnage ou à celle des découpes 2 de carton.In the following description, the terms "lower", "upper", "up", "down", "right" and "left" are used with reference to the drawings for greater ease of understanding. They are not to be understood as being limitations of the scope of the invention, in particular as to the orientation of the forming module 1 or that of the blanks 2 of cardboard.

En effet, l'orientation du module 1 de façonnage et de la découpe 2 de carton n'est ici présentée que dans le cadre d'un mode préféré de réalisation de l'invention.Indeed, the orientation of the forming module 1 and the cardboard blank 2 is presented here only in the context of a preferred embodiment of the invention.

On voit, sur la figure 1a, le poste 3 de façonnage qui porte le module 1 porte-outils conforme à l'invention.We see, on the figure 1a , the forming station 3 which carries the module 1 tool holder according to the invention.

En amont du poste 3 de façonnage, se trouve un magasin 4 de découpes 2 de carton, les découpes 2 de carton étant toutes positionnées debout dans le même sens, les unes derrière les autres dans le magasin 4.Upstream of the forming station 3, there is a magazine 4 of cardboard blanks 2, the blanks 2 of cardboard being all positioned upright in the same direction, one behind the other in the magazine 4.

Le magasin 4 stocke les découpes 2 de carton en position inclinée.The magazine 4 stores the cardboard blanks 2 in an inclined position.

L'installation comporte, de façon connue en soi, des moyens pour extraire les découpes 2 de carton une à une du magasin 4, grâce, notamment, à l'intervention d'un bras 5 de prélèvement des découpes 2 de carton qui est monté articulé sur un axe Y sensiblement horizontal. Le bras 5 comporte par ailleurs, de façon connue en soi, des ventouses 51, propres à prélever, par effet de succion, une découpe 2 dans le magasin 4.The installation comprises, in a manner known per se, means for extracting the cutouts 2 of cardboard one by one from the magazine 4, thanks, in particular, to the intervention of a picking arm 5 of the blanks 2 of cardboard which is mounted articulated on a substantially horizontal axis Y. The arm 5 further comprises, in a manner known per se, suction cups 51, adapted to take, by suction effect, a cutout 2 in the magazine 4.

Le bras 5 de prélèvement permet d'amener les découpes 2 en position sensiblement horizontale le long d'un axe X représenté sur la figure 1 a.The picking arm 5 makes it possible to bring the blanks 2 in a substantially horizontal position along an axis X represented on FIG. figure 1 at.

L'axe X, qui est longitudinal, est également l'axe suivant lequel les découpes 2 de carton sont déplacées dans le poste 3 de façonnage, entre une position 6 d'entrée et une position 7 de sortie (position 6 d'entrée à gauche du poste de façonnage et position 7 de sortie à droite du poste de façonnage).The X axis, which is longitudinal, is also the axis along which the cardboard blanks 2 are moved in the forming station 3, between an input position 6 and an output position 7 (input position 6 to left of the shaping station and 7 exit position to the right of the shaping station).

Le module 1 est monté mobile en déplacement entre la position 6 d'entrée du poste 3 de façonnage et la position 7 de sortie du poste 3 de façonnage.The module 1 is mounted movably in displacement between the input position 6 of the forming station 3 and the output position 7 of the forming station 3.

Pour ce faire, le module 1 comporte un bâti mobile qui est structuré en forme de chariot 8 de façonnage, portant les outils de façonnage, et ce module 1 comporte aussi des moyens de déplacement dudit chariot 8 entre la position 6 d'entrée et la position 7 de sortie.To do this, the module 1 comprises a mobile frame which is structured in the form of a trolley 8 for shaping, carrying the shaping tools, and this module 1 also comprises means for moving said trolley 8 between the input position 6 and the 7 exit position.

Ces moyens de déplacement sont réalisés par des glissières 9 sensiblement horizontales, sur lesquelles le chariot 8 de façonnage est monté.These displacement means are formed by substantially horizontal slideways 9, on which the shaping carriage 8 is mounted.

Les glissières 9 sont disposées en haut et en bas du poste de façonnage, de sorte que le module 1 est guidé dans sa partie supérieure et dans sa partie inférieure.The slides 9 are arranged at the top and bottom of the forming station, so that the module 1 is guided in its upper part and in its lower part.

Les moyens de déplacement du chariot 8 comportent également une courroie 10, prévue par exemple en partie supérieure du poste 3 de façonnage. La courroie 10 est reliée au chariot 8.The carriage 8 of the movement means also comprise a belt 10, provided for example in the upper part of the station 3 shaping. The belt 10 is connected to the carriage 8.

La courroie est entraînée en déplacement par un actionneur 11 qui, dans le cadre de cet exemple de réalisation, est un servomoteur apte à entraîner la courroie en déplacement dans un sens et en sens inverse. L'actionneur est notamment illustré en figure 1 b.The belt is driven in displacement by an actuator 11 which, in the context of this exemplary embodiment, is a servomotor able to drive the belt moving in one direction and in the opposite direction. The actuator is particularly illustrated in figure 1 b.

Le poste 3 de façonnage comporte, au moins à son entrée 6, un jeu de rails 12 orientés sensiblement horizontalement à une hauteur prédéterminée, sur lesquels reposent et sont déplacées les découpes 2 de carton.The forming station 3 comprises, at least at its inlet 6, a set of rails 12 oriented substantially horizontally at a predetermined height, on which rest and are moved the blanks 2 of cardboard.

Les rails 12 sont espacés d'une distance prédéterminée, en relation avec la largeur des découpes 2 de carton non façonnées, de sorte que les découpes avant façonnage soient aptes à reposer sur les deux rails 12.The rails 12 are spaced a predetermined distance, in relation to the width of the cutouts 2 of unshaped cardboard, so that the cutouts before shaping are able to rest on the two rails 12.

La position 7 de sortie pour être équipée de tels rails 12 ou comprendre un tapis 200 de convoyage et d'évacuation.The position 7 output to be equipped with such rails 12 or include a carpet 200 conveying and evacuation.

Les éléments de façonnage que comporte le module 1 porte-outils vont maintenant être décrits.The shaping elements that comprises the module 1 tool holder will now be described.

Conformément à l'invention, le module 1 porte-outils comporte un jeu de porte-outils 13 et 14 pour des outils de façonnage. Les porte-outils 13 et 14 sont disposés de part et d'autre des rails 12 sur lesquels reposent les découpes avant façonnage, c'est-à-dire que, dans le cadre de ce mode de réalisation, les outils 13 et 14 sont positionnés au-dessus et au-dessous des rails 12.According to the invention, the module 1 tool holder comprises a set of tool holders 13 and 14 for forming tools. The tool holders 13 and 14 are arranged on either side of the rails 12 on which the cutouts before shaping rest, that is to say that, in the context of this embodiment, the tools 13 and 14 are positioned above and below rails 12.

Le module 1 comporte également des moyens de déplacement de chacun des porte-outils 13 et 14 de part et d'autre d'une découpe 2, suivant une direction perpendiculaire au sens de déplacement de la découpe, c'est-à-dire suivant une direction Z montrée en figures 1 a et 1 b.The module 1 also comprises means for moving each of the tool holders 13 and 14 on either side of a blank 2, in a direction perpendicular to the direction of movement of the blank, that is to say next a Z direction shown in figures 1 a and 1 b.

Les porte-outils 13 et 14 (et par conséquent les outils qu'ils portent) se déplacent donc suivant une direction verticale, entre une position 15 inactive où les outils sont escamotés et une position 16 active dite « de façonnage ».The tool holders 13 and 14 (and therefore the tools they carry) therefore move in a vertical direction, between an inactive position 15 where the tools are retracted and an active position 16 called "shaping".

La position 15 escamotée des porte-outils 13 et 14 (et donc des outils) est la position suivant laquelle lesdits porte-outils sont les plus éloignés des rails 12 sur lesquels reposent les découpes avant façonnage.The retracted position 15 of the tool holders 13 and 14 (and therefore tools) is the position in which said tool holders are furthest removed from the rails 12 on which the cutouts before shaping rest.

La position 16 de façonnage des porte-outils 13, 14 (et donc des outils) est la position suivant laquelle les porte-outils sont au plus près des rails 12 sur lesquels reposent les découpes telle que montrée sur la figure 3.The position 16 for shaping tool holders 13, 14 (and therefore tools) is the position in which the tool holders are as close as possible to the rails 12 on which the cutouts rest as shown on FIG. figure 3 .

Les moyens de déplacement des porte-outils 13, 14 entre la position 16 de façonnage et la position 15 escamotée sont portés par le chariot 8 de façonnage, de sorte que le module est réalisé de la façon la plus compacte possible.The means for moving the tool holders 13, 14 between the shaping position 16 and the retracted position 15 are carried by the shaping carriage 8, so that the module is produced in the most compact manner possible.

Ces moyens de déplacement comprennent au moins une glissière 17 qui est illustrée sur les figures 1 a et 1 b.These moving means comprise at least one slide 17 which is illustrated on the figures 1 a and 1 b.

La glissière 17 est une glissière verticale, sur laquelle sont montés libres en déplacement (ou mobiles) les porte-outils 13 et 14.The slide 17 is a vertical slide, on which are mounted freely moving (or mobile) the tool holders 13 and 14.

Les porte-outils 13, 14 sont respectivement reliés à une courroie 18 et 180.The tool holders 13, 14 are respectively connected to a belt 18 and 180.

Des actionneurs 19 et 190, respectivement, assurent l'entraînement en rotation des courroies 18 et 180 dans un sens et en sens inverse.Actuators 19 and 190, respectively, provide rotational drive of the belts 18 and 180 in one direction and in the opposite direction.

Les actionneurs 19 et 190 sont, dans le cadre de ce mode de réalisation, des servomoteurs.The actuators 19 and 190 are, in the context of this embodiment, servomotors.

L'entraînement en rotation des courroies 18 et 180 dans un sens et en sens inverse, assure le déplacement des porte-outils 13, 14 (et donc des outils qu'ils portent) entre la position 15 escamotée et la position 16 de façonnage.The rotational drive of the belts 18 and 180 in a direction and in the opposite direction, ensures the movement of the tool holders 13, 14 (and therefore the tools they carry) between the retracted position and the position 16 shaping.

On prévoit que les outils de façonnage sont montés amovibles sur les porte-outils 13 et 14.It is expected that the forming tools are removably mounted on the tool holders 13 and 14.

De cette façon, on peut utiliser des outils de façonnage de formes différentes, en fonction de la forme que l'on souhaite donner à la découpe 2 de carton (et, en particulier, suivant l'application que l'on souhaite donner au procédé qui sera décrit ultérieurement).In this way, it is possible to use shaping tools of different shapes, depending on the shape that it is desired to give to the blank 2 of cardboard (and, in particular, according to the application that it is desired to give to the process which will be described later).

Suivant le mode de réalisation illustré en particulier sur les figures 2 à 5, les outils sont respectivement constitués d'un poinçon 130 et d'une matrice 140 de forme complémentaire.According to the embodiment illustrated in particular on the Figures 2 to 5 the tools consist respectively of a punch 130 and a matrix 140 of complementary shape.

Comme on peut le voir sur les figures, le poinçon 130 a la forme d'un disque d'une certaine épaisseur, et la matrice 140 a sensiblement la forme d'une cloche, la forme interne de la cloche épousant la forme externe du disque.As can be seen in the figures, the punch 130 has the shape of a disc of a certain thickness, and the die 140 is substantially bell-shaped, the internal shape of the bell conforming to the external shape of the disc .

On va maintenant décrire le procédé de façonnage d'une découpe 2 de carton, entre la position 6 d'entrée du poste 3 de façonnage et la position 7 de sortie du poste 3 de façonnage.We will now describe the process of forming a blank 2 of cardboard, between the 6 position of entry of the shaping station 3 and the 7 position of the exit station 3 shaping.

Conformément au procédé selon l'invention, ce dernier consiste à assurer le déplacement de la découpe 2 de carton au moyen des outils 130 et 140 de façonnage, entre la position 6 d'entrée et la position 7 de sortie du poste 3 de façonnage, en même temps que la découpe 2 de carton est façonnée par lesdits outils 130 et 140.According to the method according to the invention, the latter consists in ensuring the displacement of the cardboard blank 2 by means of the forming tools 130 and 140, between the input position 6 and the output position 7 of the forming station 3, at the same time as the blank 2 of cardboard is shaped by said tools 130 and 140.

La première étape, illustrée en figure 2, montre que les outils 130 et 140 sont en position 15 escamotée lorsqu'une découpe 2 de carton est amenée en position 6 à l'entrée du poste 3 de façonnage, sur les rails 12.The first step, illustrated in figure 2 shows that the tools 130 and 140 are in the retracted position when a blank 2 of cardboard is brought into position 6 at the entrance of the forming station 3, on the rails 12.

La figure 3 illustre la seconde étape, assurant le façonnage de la découpe 2.The figure 3 illustrates the second step, ensuring the shaping of the blank 2.

Dans cette étape, la découpe 2 est déplacée suivant l'axe X, sur les rails 12, par un taquet 20 de déplacement, jusqu'à un capteur 21 qui détecte la présence et le positionnement de ladite découpe.In this step, the cutout 2 is moved along the axis X, on the rails 12, by a stop 20 of displacement, to a sensor 21 which detects the presence and positioning of said cut.

En même temps, les outils 130 et 140 sont amenés en position 16 de façonnage, c'est-à-dire appliqués contre les deux faces opposées de la découpe 2 reposant sur les rails 12.At the same time, the tools 130 and 140 are brought into the shaping position 16, that is to say applied against the two opposite faces of the cutout 2 resting on the rails 12.

Pour ce faire, les courroies 18 et 180 sont entraînées en rotation grâce aux actionneurs 19 et 190 (non représentés sur les figures 2 à 5).To do this, the belts 18 and 180 are rotated by the actuators 19 and 190 (not shown in FIGS. Figures 2 to 5 ).

Suivant une troisième étape illustrée en figure 4, le chariot 8 est entraîné en déplacement horizontal, en même temps que les outils 130 et 140 sont entraînés en déplacement vertical.Following a third step illustrated in figure 4 , the carriage 8 is driven in horizontal displacement, at the same time as the tools 130 and 140 are driven in vertical displacement.

Ce double mouvement assure le façonnage de la découpe en même temps que son déplacement dans le poste 3 de façonnage.This double movement ensures the shaping of the cut at the same time as its movement in the workstation 3.

Au même moment, le taquet 20 qui a permis d'amener la découpe 2 de carton est déplacé en sens inverse, en direction du magasin 4, de manière à se mettre en position pour prendre en charge une nouvelle découpe 2 de carton (figure 4).At the same time, the cleat 20 which made it possible to bring the blank 2 of cardboard is moved in the opposite direction, towards the magazine 4, so as to be in position to take charge of a new cut 2 of cardboard ( figure 4 ).

L'ultime étape du procédé conforme à l'invention est illustrée en figure 5.The final stage of the process according to the invention is illustrated in figure 5 .

Suivant cette dernière étape, les outils 130 et 140 sont entraînés en déplacement vertical vers leur position 15 escamotée, libérant ainsi la découpe 2 de carton façonnée, sur un tapis 200 d'évacuation situé en position 7 de sortie.In this last step, the tools 130 and 140 are driven in vertical displacement towards their retracted position, thus releasing the blank 2 of shaped cardboard on an evacuation belt 200 located in the output position 7.

La découpe 2 de carton façonnée est alors prise en charge par ce tapis pour être entraînée vers un poste situé en aval d'une installation conforme à l'invention, tel que, par exemple, un poste de remplissage.The cut 2 of shaped cardboard is then supported by this mat to be driven to a post located downstream of an installation according to the invention, such as, for example, a filling station.

Dans l'exemple illustré en figure 5, les outils 130 et 140 sont entraînés en position 15 escamotée alors que le chariot 8 est immobile. Cette étape se déroule pendant une durée suffisante pour dégager la découpe ; après quoi, les outils 130 et 140 sont entraînés en déplacement vers la position 15 escamotée, puis le chariot 8 est entraîné en déplacement vers la position 6 d'entrée du poste 3 de façonnage.In the example shown in figure 5 the tools 130 and 140 are driven in the retracted position while the carriage 8 is stationary. This step takes place for a sufficient time to clear the cutout; after which, the tools 130 and 140 are moved to the retracted position 15, then the carriage 8 is moved to the position 6 of the input of the forming station 3.

Pour augmenter encore les cadences de formage de découpes 2, on peut mettre en oeuvre deux modules 1 et 1' porte-outils, comme illustrés en figure 6.To further increase the forming rates of blanks 2, it is possible to implement two modules 1 and 1 'tool holder, as illustrated in FIG. figure 6 .

Conformément à l'invention, chaque module porte-outils 1 et 1' comprend au moins un chariot 8 de façonnage portant les outils 130 et 140 de façonnage (par analogie : chariot 8' et outils 130' et 140').According to the invention, each tool holder module 1 and 1 'comprises at least one shaping carriage 8 carrying the shaping tools 130 and 140 (by analogy: carriage 8' and tools 130 'and 140').

Dans le cadre de ce mode de réalisation, chaque chariot 8 et 8' de façonnage de chaque module 1 et 1' prend en charge, à tour de rôle, des découpes 2 de carton arrivant en position 6 d'entrée du poste de façonnage.In the context of this embodiment, each trolley 8 and 8 'for shaping each module 1 and 1' supports, in turn, cardboard blanks 2 arriving at the input position 6 of the forming station.

La prise en charge à tour de rôle est réalisée à intervalles réguliers pour un fonctionnement optimum de l'installation.The support takes turns at regular intervals for optimum operation of the installation.

Grâce au fonctionnement simultané et décalé des deux chariots 8 et 8', une telle installation permet d'atteindre des cadences de réalisation de découpes 2 de carton façonnées de l'ordre de 50 pièces par minute.By virtue of the simultaneous and offset operation of the two carriages 8 and 8 ', such an installation makes it possible to achieve production rates of shaped cardboard blanks 2 of the order of 50 pieces per minute.

Cette installation comprend en outre un dispositif 80 qui permet de maintenir la découpe formée quand la matrice et le poinçon sont escamotés.This installation further comprises a device 80 which makes it possible to maintain the cutout formed when the die and the punch are retracted.

Le dispositif 80 n'a pas été représenté sur toutes les figures pour une raison de clarté de ces dernières. Il peut toutefois être aisément réalisé par l'homme du métier à partir des informations qui sont exposées par la suite.The device 80 has not been shown in all the figures for reasons of clarity of the latter. It can, however, be easily realized by those skilled in the art from the information which is exposed thereafter.

Par ailleurs, une telle installation peut également comprendre, comme il est illustré sur la figure 6a, des moyens 22 pour encoller une partie de la découpe 2 de carton, de sorte qu'elle soit fixée suivant une certaine position après façonnage.Moreover, such an installation may also include, as illustrated on the figure 6a , means 22 for gluing a portion of the blank 2 of cardboard, so that it is fixed in a certain position after forming.

Les figures 6a et 6b, comme indiqué précédemment, ne sont que d'autres vues de l'installation illustrée en figure 6, assurant une meilleure perception visuelle de la disposition de chacun des modules 1 et 1'.The Figures 6a and 6b , as mentioned earlier, are only other views of the illustrated installation in figure 6 , providing a better visual perception of the disposition of each of the modules 1 and 1 '.

La figure 6a a pour particularité de montrer le décalage de fonctionnement entres les modules 1 et 1'.The figure 6a has the particularity of showing the operating offset between the modules 1 and 1 '.

En particulier, on note que le module 1' se trouve à l'entrée du poste 3 de façonnage, avec les outils 130 et 140 en position 15 escamotée, alors que le module 1' se trouve en position 7 de sortie du poste de façonnage avec les outils 130' et 140' en position 16 de façonnage.In particular, it is noted that the module 1 'is at the entrance of the workstation 3, with the tools 130 and 140 in the retracted position 15, while the module 1' is in position 7 of exit of the work station with the tools 130 'and 140' in the shaping position 16.

Ainsi, dans le cadre du mode de réalisation illustré, les modules 1 et 1' sont décalés d'un demi-cycle de façonnage dans leurs étapes de façonnage, l'un des modules 1 commençant le cycle de façonnage alors que l'autre module 1' le termine.Thus, in the context of the illustrated embodiment, the modules 1 and 1 'are offset by a half-cycle of shaping in their shaping steps, one of the modules 1 starting the shaping cycle while the other module He finishes it.

La figure 6b illustre schématiquement ce que l'on peut apercevoir lorsqu'on regarde l'installation dans le prolongement du tapis d'évacuation situé au niveau de la position 7 de sortie, illustré sur la figure 6a.The figure 6b schematically illustrates what can be seen when looking at the installation in the extension of the discharge belt located at the position 7 output, shown on the figure 6a .

Il est par ailleurs à noter que les moyens permettant le déplacement, aussi bien des outils de façonnage, que des chariots 8 et 8', ne sont pas réalisés par des systèmes rails-courroies-actionneurs, mais par des systèmes à vérins que l'homme du métier est à même de monter à leur place.It should also be noted that the means making it possible to move both the shaping tools and the carriages 8 and 8 'are not made by rail-belt-actuator systems, but by jack systems that the a person skilled in the art is able to ride in their place.

On comprend ainsi que l'invention n'est pas limitée à certains moyens de déplacement des différents éléments du module 1, 1' de façonnage, mais qu'elle s'étend au contraire à la mise en oeuvre de tout moyen équivalent.It is thus understood that the invention is not limited to certain means for moving the different elements of the forming module 1, 1 ', but that it extends on the contrary to the implementation of any equivalent means.

On va maintenant s'intéresser aux figures 7 à 9, pour décrire le fonctionnement du procédé de façonnage conforme à l'invention qui met en oeuvre deux modules 1 et 1' de façonnage.We will now be interested in Figures 7 to 9 , to describe the operation of the shaping method according to the invention which implements two shaping modules 1 and 1 '.

Sur la figure 7, on voit que le module 1 entame le façonnage d'une découpe 2 de carton par déplacement en translation verticale des outils 130 et 140 en position 16 de façonnage. En même temps, le module 1' libère une découpe 2' façonnée en escamotant les outils 130' (poinçon) et 140' (matrice) vers la position 15 escamotée.On the figure 7 , it is seen that the module 1 begins shaping a blank 2 cardboard by vertical translation movement of the tools 130 and 140 in 16 shaping position. At the same time, the module 1 'releases a cut 2' shaped by retracting the tools 130 '(punch) and 140' (die) to the retracted position.

Sur la figure 8, est montrée une seconde étape de ce procédé mettant en oeuvre deux modules 1 et 1'.On the figure 8 is shown a second step of this method using two modules 1 and 1 '.

Il est montré que le module 1 déplace et façonne la découpe 2 de carton grâce à un déplacement vertical des outils 130 (poinçon) et 140 (matrice) simultanément à un déplacement horizontal du module 1. Pendant ce temps, le module 1' est ramené vers la position 6 d'entrée du poste 3 de façonnage, les outils 130' et 140' étant totalement en position 15 escamotée lorsqu'ils arrivent à la position 6 d'entrée. Pendant ce temps également, une nouvelle découpe 30 est amenée en position 6 d'entrée du poste de façonnage, après avoir été encollée grâce aux moyens d'encollage 22.It is shown that the module 1 moves and shapes the cardboard blank 2 by vertically moving the tools 130 (punch) and 140 (die) simultaneously with a horizontal movement of the module 1. During this time, the module 1 'is brought back to the input position 6 of the forming station 3, the tools 130 'and 140' being completely in the retracted position when they arrive at the input position 6. During this time also, a new cutout 30 is brought to the input position 6 of the processing station, after having been glued by the gluing means 22.

La figure 9 illustre une ultime étape suivant laquelle le module 1 libère la découpe 2 de carton façonnée au voisinage la position 7 de sortie du poste 3 de façonnage.The figure 9 illustrates a final step in which the module 1 releases the cut 2 of cardboard shaped near the 7 outlet position of the workstation 3.

Au même moment, le module 1' commence le façonnage de la nouvelle découpe 30, en déplaçant les outils 130' et 140' jusqu'à la position 16 de façonnage. Au même moment également, une nouvelle découpe est prélevée par le bras 5, puis déposée sur les rails 12, comme le montre schématiquement la figure 9 par la flèche P de prélèvement, et ainsi de suite.At the same time, the module 1 'begins shaping the new cutout 30, moving the tools 130' and 140 'to the position 16 shaping. At the same time also, a new cut is taken by the arm 5 and then deposited on the rails 12, as schematically shown in FIG. figure 9 by the picking arrow P , and so on.

Pour permettre à la découpe 2 façonnée de ne pas être éjectée hors de l'installation pendant l'escamotage de la matrice, le dispositif 80 est actionné. Il va maintenant être décrit.To allow the shaped cut 2 not to be ejected from the installation during the retraction of the die, the device 80 is actuated. It will now be described.

Le dispositif 80 comporte un plateau 81 muni de ventouses 82.The device 80 comprises a plate 81 provided with suction cups 82.

Les ventouses 82 sont aptes à retenir le fond d'une découpe formée par succion. Elles sont ainsi reliées à des moyens d'aspiration, comme il est en soi connu de l'homme du métier.The suction cups 82 are able to retain the bottom of a cut formed by suction. They are thus connected to suction means, as is in itself known to those skilled in the art.

Pour permettre le placement du plateau 81 sous la découpe formée, ainsi que son escamotage, on prévoit de monter le plateau 81 à l'extrémité d'un vérin 83, et de monter l'ensemble mobile en déplacement vertical.To allow the placement of the plate 81 under the formed cut, and its retraction, it is planned to mount the plate 81 at the end of a cylinder 83, and to mount the moving assembly in vertical displacement.

Le vérin 83 permet de déplacer le plateau 81 suivant un mouvement horizontal.The cylinder 83 moves the plate 81 in a horizontal movement.

Le déplacement vertical peut être assuré par un montage de l'ensemble sur un rail 84, relié à un vérin électrique, non représenté.The vertical displacement can be ensured by mounting the assembly on a rail 84, connected to an electric jack, not shown.

Pour permettre l'insertion du plateau 81 dans la matrice avant l'escamotage de la matrice et du poinçon, la matrice comporte une ouverture de passage (non représentée) dont les dimensions sont sensiblement supérieures à celles du plateau 81 équipé des ventouses 82.To allow the insertion of the plate 81 into the matrix before the retraction of the matrix and the punch, the matrix comprises a passage opening (not shown) whose dimensions are substantially greater than those of the plate 81 equipped with the suction cups 82.

La matrice comporte également un passage latéral vertical pour qu'elle puisse se dégager du dispositif 80, lorsqu'elle réalise un mouvement vertical lorsqu'elle s'escamote (voir figures 7 et 8 par exemple).The die also has a vertical lateral passage so that it can disengage from the device 80, when it makes a vertical movement when it retracts (see Figures 7 and 8 for example).

Le mouvement vertical du dispositif 80 est réalisé quand la découpe formée est totalement dégagée de la matrice. En effet, quand la découpe est formée, le dispositif de maintien 80 emmène la découpe formée sur le tapis d'évacuation en position 7 de sortie du poste. Puis, les ventouses 82 sont désactivées et le dispositif 80 est légèrement abaissé pour le dégager de la découpe. Enfin, le plateau 81 est escamoté par actionnement du vérin 83, puis il est rabaissé à un niveau inférieur.The vertical movement of the device 80 is realized when the cutout formed is totally free of the matrix. Indeed, when the cutout is formed, the holding device 80 takes the cutout formed on the conveyor belt in position 7 output station. Then, the suction cups 82 are deactivated and the device 80 is lowered slightly to disengage it from the blank. Finally, the plate 81 is retracted by actuation of the cylinder 83, then it is lowered to a lower level.

La description qui précède montre comment le procédé conforme à l'invention permet de façonner des découpes de carton pour réaliser des caisses qui peuvent être remplies dans un poste aval ; ou bien encore, pour réaliser des présentoirs (barquettes ou plateaux de présentation) en carton, qui sont usuellement utilisés dans les grandes surfaces pour présenter une série de produits.The foregoing description shows how the process according to the invention makes it possible to form cardboard blanks for producing boxes. which can be filled in a downstream post; or even to produce displays (trays or presentation trays) cardboard, which are usually used in large areas to present a series of products.

D'autres applications sont également possibles grâce au procédé et au module conformes à l'invention.Other applications are also possible thanks to the method and module according to the invention.

Les figures 10a et 10b illustrent en particulier une application du procédé conforme à l'invention au coiffage de lots d'articles.The Figures 10a and 10b illustrate in particular an application of the method according to the invention to the capping of batches of articles.

On retrouve sur la figure 10a l'installation décrite précédemment sur les figures 1 a et 1 b, à savoir le magasin 4, le bras 5 de prélèvement, les moyens 9 et 10 de déplacement horizontal du chariot 8 et les moyens 18 et 180 de déplacement vertical des outils de façonnage.We find on the figure 10a the installation described previously on figures 1 a and 1b, namely the magazine 4, the picking arm 5, the means 9 and 10 for horizontal displacement of the carriage 8 and the means 18 and 180 for vertical displacement of the forming tools.

Les outils de façonnage sont différents de ceux présentés précédemment. L'outil situé en partie supérieure du poste 3 de façonnage est une coiffe 23 en forme de cloche, faisant office de matrice installée sur le porte-outil 13. L'outil de façonnage inférieur est installé sur le porte-outil 14 et il est constitué par au moins deux plateaux-poussoir 24 sur lesquels des lots 40 de produits sont pris en charge afin d'être coiffés par une découpe 25 de carton directement façonnée sur les lots 40 de produits.The shaping tools are different from those previously presented. The tool located in the upper part of the forming station 3 is a bell-shaped cap 23, acting as a die installed on the tool holder 13. The lower forming tool is installed on the tool holder 14 and it is consisting of at least two push plates 24 on which batches 40 of products are supported to be capped by a cardboard cut 25 directly shaped on the batches 40 of products.

Les lots 40 de produits sont réalisés par un ensemble de produits alignés les uns à côté des autres dans une barquette 41. Les lots 40 de produits sont amenés en amont du poste 3 de façonnage sur un convoyeur 26.The batches 40 of products are produced by a set of products aligned next to each other in a tray 41. The batches 40 of products are brought upstream of the processing station 3 on a conveyor 26.

Le convoyeur 26 s'étend au moins sur toute la longueur du poste 3 de façonnage.The conveyor 26 extends at least the entire length of the station 3 shaping.

Les lots 40 sont déplacés sur le convoyeur 26 jusqu'à venir se positionner à un emplacement déterminé par un référentiel.The batches 40 are moved on the conveyor 26 until they are positioned at a location determined by a reference frame.

Le référentiel comporte, d'une part, un taquet 27 de positionnement d'un lot 40 de produit, lequel taquet 27 est guidé sur le port porte-outils 14, et, d'autre part, des éléments 28 de positionnement, prévus sur le porte-outils 13 pour indexer la position de la découpe par rapport à la position du lot 40 de produits, avant que le module 1 ne façonne la découpe directement sur le lot 40 de produits, afin notamment de le fermer.The reference system comprises, on the one hand, a cleat 27 for positioning a batch 40 of product, which cleat 27 is guided on the tool-carrying port 14, and, on the other hand, positioning elements 28, provided on the tool holder 13 for indexing the position of the blank with respect to the position of the batch 40 of products, before the module 1 forms the cut directly on the batch 40 of products, in particular to close it.

On peut prévoir également des moyens d'encollage (non représentés) qui permettraient de déposer de la colle sur une certaine partie de la découpe 25 de carton afin que, une fois la découpe 25 de carton façonnée, elle vienne se fixer sur la barquette 41.It is also possible to provide sizing means (not shown) which would make it possible to deposit glue on a certain part of the cardboard blank 25 so that, once the shaped cardboard blank 25 has been cut, it will be fixed on the tray 41 .

Pour permettre le façonnage de la découpe 25 de carton, cette dernière est guidée dans un couloir horizontal grâce à des rails 29 de guidage (voir figure 10b), jusqu'à ce qu'elle soit prisonnière entre le haut du lot 40 de produits et l'extrémité de la coiffe 23.To permit the forming of the cardboard cut 25, the latter is guided in a horizontal corridor by means of guide rails 29 (see FIG. figure 10b ), until it is trapped between the top of the batch of products 40 and the end of the cap 23.

Les rails 29 de guidage sont disposés latéralement par rapport au couloir horizontal de guidage de la découpe et ils supportent les bords latéraux desdites découpes pendant leur convoyage jusqu'au référentiel.The guide rails 29 are arranged laterally with respect to the horizontal guideway of the cut and they support the lateral edges of said cuts during their conveying to the reference frame.

Les rails 29 sont montés escamotables sur les côtés du couloir (voir flèches sur la figure 10b) de sorte à libérer la découpe 25 lorsqu'elle est prise en charge par les outils de façonnage.The rails 29 are mounted retractable on the sides of the corridor (see arrows on the figure 10b ) so as to release the blank 25 when supported by the forming tools.

Pour ce faire, les plateaux-poussoir 24 qui supportent le lot 40 de produits à coiffer, sont entraînés en déplacement vertical vers le haut et en déplacement horizontal jusqu'à ce que la partie supérieure du lot 40 vienne en butée contre la découpe 25 de carton, elle-même en mouvement suivant une direction horizontale.To do this, the push plates 24 which support the batch 40 of products to be combed, are driven in vertical displacement upwards and in horizontal displacement until the upper part of the batch 40 comes into abutment against the cutout 25. carton, itself moving in a horizontal direction.

Lorsque la découpe 25 de carton est prisonnière entre l'extrémité de la coiffe 23 et la partie supérieure du lot 40 de produits, les rails 29 de guidage sont escamotés et la découpe 25 de carton est façonnée sur le lot 40 de produits.When the cardboard blank is trapped between the end of the cap 23 and the top of the product batch 40, the guide rails 29 are retracted and the cardboard blank 25 is formed on the batch 40 of products.

Une fois le lot 40 de produits entièrement recouvert de la découpe 25 de carton façonnée, l'ensemble est déposé en position 7 de sortie du poste 3 de façonnage, grâce aux plateaux-poussoir 24 qui déposent le lot sur le convoyeur 26 lorsqu'ils descendent, entraînés par la courroie 18 de manoeuvre du porte-outils (voir figure 10b).Once the batch 40 of products completely covered with the cut 25 of shaped cardboard, the set is deposited in position 7 of output of the station 3 shaping, thanks to the push plates 24 which deposit the batch on the conveyor 26 when descend, driven by the belt 18 for operating the tool holder (see figure 10b ).

Sur la figure 10b, on remarque également que les plateaux-poussoir 24 sont réalisés par les extrémités de bras, montés sur la glissière 17.On the figure 10b it is also noted that the push plates 24 are formed by the ends of the arms, mounted on the slide 17.

On pourrait toutefois prévoir un autre mode de réalisation alternatif à l'intervention de deux plateaux-poussoir 24 dont l'écartement est fixe.However, we could provide another alternative embodiment to the intervention of two push plates 24 whose spacing is fixed.

La figure 11 montre, en effet, un plateau-poussoir 35 installé sur le porte-outils 14 et sur lesquels pourrait reposer un lot 40 de produits conditionnés en barquette à recouvrir. Le plateau-poussoir 35 est réalisé avec une largeur modifiable, et les convoyeurs 36 sont montés mobiles en déplacement horizontal (illustrés schématiquement par la référence 42) de sorte que leur écartement peut varier et être fixé en fonction de la largeur de la barquette du lot de produit 40.The figure 11 shows, in fact, a pusher plate 35 installed on the tool holder 14 and on which could rest a batch 40 of packaged products trays to cover. The push plate 35 is made with a modifiable width, and the conveyors 36 are movably mounted in horizontal displacement (illustrated schematically by the reference 42) so that their spacing can vary and be fixed according to the width of the tray of the batch of product 40.

On pourrait également réaliser différemment la coiffe 23.The cap 23 could also be made differently.

La figure 12 illustre une coiffe 23 dont la partie latérale est réalisée par des ailettes (ou volets) 31 qui sont articulées chacune au niveau de leur extrémité supérieure (voir flèche sur la figure 12).The figure 12 illustrates a cap 23, the lateral portion is formed by fins (or flaps) 31 which are each articulated at their upper end (see arrow on the figure 12 ).

La figure 13 illustre encore un autre mode d'application du procédé conforme à l'invention pour la fermeture de caisses.The figure 13 illustrates yet another mode of application of the method according to the invention for closing crates.

En effet, on voit sur la figure 13 une installation comprenant un convoyeur 60 qui assure le déplacement de caisses 61 présentant un couvercle rabattable, en position ouverte, à l'entrée 6 du poste 3 de façonnage.Indeed, we see on the figure 13 an installation comprising a conveyor 60 which moves crates 61 having a folding lid, in the open position, to the inlet 6 of the forming station 3.

Un module 62 conforme à l'invention comporte, au-dessus du convoyeur 60, un premier outil 63 de façonnage (outil de façonnage supérieur) qui se présente sous la forme d'un plateau 64 central.A module 62 according to the invention comprises, above the conveyor 60, a first forming tool 63 (upper forming tool) which is in the form of a central plate 64.

Le plateau 64 présente, le long de ses côtés, des volets 65 qui sont articulés.The plate 64 has, along its sides, flaps 65 which are articulated.

En dessous du convoyeur 60, se trouve le second outil de façonnage 66, présentant un plateau-support 67 qui a pour fonction de prendre en charge la caisse 61 lorsque cette dernière est positionnée précisément contre un élément 68 de repère.Below the conveyor 60, there is the second forming tool 66, having a support plate 67 whose function is to take charge of the box 61 when the latter is positioned precisely against a marker element 68.

Cet élément 68 de repère assure également l'orientation correcte de la caisse 61 par rapport au plateau 64 de l'outil 63. De cette manière, lorsque les outils de façonnage passent de leur position 15 escamotée à leur position 16 de façonnage, le plateau 64 prend appui sur la surface supérieure de la caisse 61 et les volets 65 articulés viennent rabattre correctement les parties 69 du couvercle qui sont rabattables sur-les faces latérales de la caisse 61.This marker element 68 also ensures the correct orientation of the box 61 with respect to the plate 64 of the tool 63. In this way, when the forming tools pass from their retracted position to their position 16 of shaping, the plate 64 is supported on the upper surface of the box 61 and the hinged flaps 65 correctly fold down the parts 69 of the lid which are foldable on the lateral faces of the box 61.

Afin de maintenir les parties 69 rabattables du couvercle de la caisse 61, on prévoit de les encoller préalablement au voisinage de la position 6 d'entrée du poste 3 de façonnage.In order to maintain the parts 69 foldable cover of the box 61, it is expected to glue prior to the vicinity of the position 6 of the input station 3 shaping.

Pour ramener le couvercle de la caisse 61 d'une position ouverte (dans laquelle il se trouve au moment de rentrer dans l'installation) à une position fermée, avant rabat des parties 69, on peut prévoir un déplacement latéral transversal du module 62, ou à tout le moins de l'outil 63 de façonnage. La plaque 64 et les volets 65 pourraient ainsi rabattre le couvercle avant d'actionner les volets 65 pour rabattre les parties 69 contre les faces latérales de la caisse 61.To bring the lid of the box 61 from an open position (in which it is at the time of entering the installation) to a closed position, before flap portions 69, may be provided a transverse lateral displacement of the module 62, or at least the shaping tool 63. The plate 64 and the flaps 65 could thus fold down the lid before actuating the flaps 65 to fold the parts 69 against the lateral faces of the box 61.

On comprend de la description qui précède comment l'invention permet de façonner des découpes de carton différentes, grâce notamment aux moyens mis en oeuvre pour changer les outils de façonnages sur le module de façonnage.It is understood from the foregoing description how the invention makes it possible to shape different cardboard blanks, thanks in particular to the means used to change the forming tools on the forming module.

On comprend également comment le procédé conforme à l'invention permet d'atteindre des cadences supérieures à celles que permettent d'obtenir les dispositifs actuels, notamment en façonnant la découpe en même temps qu'elle est déplacée. On comprend en particulier comment on peut doubler la cadence actuelle grâce à la mise en oeuvre de deux modules conformes à l'invention.It is also understood how the method according to the invention achieves higher rates than those that allow the current devices, especially by shaping the cut at the same time it is moved. It is understood in particular how one can double the current rate thanks to the implementation of two modules according to the invention.

Il devra être compris que l'invention n'est toutefois pas limitée aux modes de réalisation qui ont été décrits ci-dessus.It should be understood that the invention is however not limited to the embodiments which have been described above.

En particulier, on comprend aisément que la réalisation des moyens de déplacement du module sur des rails, ou bien même celle des outils, pourrait être différente sans sortir du cadre de l'invention.In particular, it is easily understood that the realization of the module moving means on rails, or even that tools, could be different without departing from the scope of the invention.

Notamment, on voit en figure 13 par exemple, que de tels moyens peuvent être réalisés par des vérins ou par des systèmes à glissières.In particular, we see figure 13 for example, such means can be made by jacks or slide systems.

L'invention n'est donc pas limitée aux modes de réalisation cités précédemment mais s'étend à la réalisation de tout moyen équivalent.The invention is therefore not limited to the embodiments mentioned above but extends to the realization of any equivalent means.
