Definitions
- the present invention relates to a device for rotating flat objects on themselves, while transporting them successively in a given direction.
- the invention finds a particularly advantageous, but not exclusive, application in the field of the manufacture of corrugated packaging boxes.
- the manufacture of boxes is traditionally done online, by folding and gluing cuts by means of a machine commonly called folder-gluer.
- folder-gluer Such a processing machine is usually in the form of a succession of modules in which are distributed the various functional arrangements which are responsible for performing the multiple elementary operations necessary for making boxes.
- Each module has its own transport system for cuts, usually roller or belt conveyors, but the assembly is arranged in such a way that the conveying is effected globally continuously over the entire length of the folder-gluer. .
- pivoting devices there are those which implement two conveyors placed side by side, parallel to the conveying direction of the cuts. Thus positioned, these conveyors are able to jointly support each cut during its conveyance. And since they are also animated by different speeds, they naturally tend to translate each cut while rotating it on itself.
- the assembly is generally arranged so that the flat pivoting operates on 90 °.
- This type of pivoting device has the disadvantage of being primarily adapted to the compact cardboard, that is to say the cuts of small and medium formats. Its effectiveness is indeed significantly reduced when the cuts are large sizes as is often the case with corrugated cardboard.
- the technical problem to be solved by the object of the present invention is to propose a device for pivoting a succession of flat objects, comprising two conveyors which are arranged parallel to one another in order to carry each flat object by supporting it jointly, and which are able to be animated with different speeds to rotate each object flat while carrying it.
- the pivoting device makes it possible to avoid the problems of the state of the art by being perfectly adapted to large flat objects, and in particular to those made of corrugated cardboard, while remaining fully usable for objects of standard sizes, even of reduced sizes, which is made of compact cardboard.
- each conveyor is mounted adjustable in the transverse position individually.
- flat object extends to any flattened and thin object, regardless of its outline, its format or the material that composes it, such as an entire sheet, a pre-cut sheet, a set of poses or cuts punctually attached to each other, an individual pose or cut, a folded box, etc.
- a flat object can be made of a material and particularly in paper, compact cardboard, corrugated cardboard, plastic, etc.
- the term conveyor generally refers to any device capable of transporting a flat object, such as a roller conveyor, a conveyor belt, a juxtaposition of conveyor belts, a conveyor belt, or to a combination of these different types of conveyors.
- An adjustable mounted conveyor in the transverse position means that its positioning can be changed by moving it laterally, regardless of how the movement is made.
- a conveyor can for example be removably mounted, that is to say, it is able to be disassembled, moved and reassembled to another position.
- the conveyor can also be mounted movably, that is to say, it is able to be moved between an infinity of operating positions, following a set motion along a predetermined path of movement.
- the invention as thus defined has the advantage of having conveyors whose position is modifiable, but especially whose relative spacing is adjustable. Indeed, as each conveyor can be moved individually, it is possible to change its position independently of that of its counterpart. This makes it possible to vary the distance separating the two conveyors, independently of their respective transverse positions. It then becomes possible to adjust this relative spacing, in particular according to the size of the objects to be treated and / or their disposition when they are upstream of the pivoting device.
- conveyors are generally remote when it comes to processing large format objects, or elongated objects in the direction of their length (Fig. 4).
- conveyors are close together when it comes to processing objects of smaller size, or elongated objects in the direction of their width (Fig. 5).
- a pivoting device according to the invention is compatible both with flat objects of large dimensions, and in particular those made of corrugated cardboard, with objects of smaller sizes, which are made of cardboard compact.
- FIG. 1 illustrates a folder-gluer in which is integrated a pivot unit implementing two pivoting devices according to the invention
- FIG. 2 is a perspective view from above of the pivot unit visible in Figure 1;
- FIG. 4 shows the pivoting unit in a first operating configuration for treating elongate objects in the direction of their length
- FIG. 5 in turn shows the pivot unit in a second operating configuration for treating elongated objects in the direction of their width.
- Fig. 1 illustrates a folder-gluer 100 whose function is to fold and glue a succession of flat objects 101 in the form of blanks, in order to manufacture corrugated cardboard folding boxes.
- this folder-gluer 100 is conventionally composed of a feeder 110, an alignment module 120, a first folding module 130, a precasement module 140, a gluing module 150, a second folding module 160, a transfer module 170 and a receiving module 180.
- Fig. 1 shows in addition that the folder-gluer 100 is also equipped with a pivoting unit 1 which is located between the first folding module 130 and the precasement module 140. Thus positioned, this pivoting unit 1 is responsible for turning to flatten each blank 101 while transporting it from the first folding module 130 to the precuring module 140. As can be seen more clearly in FIG. 2, the pivot unit 1 is composed of two pivoting devices 10 and 20 which are arranged one after the other in the conveying direction.
- the pivoting devices 10 and 20 are arranged substantially adjacent. This characteristic means that they are placed directly one after the other, and that they therefore act in a directly successive manner. This implies that no intermediate device or space is present between the two, which makes it possible to optimize the cumulative action of the two successive pivoting devices 10 and 20.
- the pivot unit 1 may further comprise an input conveyor which is placed directly upstream of the successive pivoting devices 10 and 20, and which is able to to transport each cut 101 only by supporting it from below.

- each conveyor 11, 12; 21, 22 is exercised in a linear translational motion.
- the interest of this type of movement is to be particularly easy to guide and generate. This makes it possible to structurally simplify each pivoting device 10 and 20, and thus to improve its reliability while lowering its cost price.
- each pivoting device 10 and 20 is provided with guide means 30 which are able to guide the transverse displacement of each conveyor 11, 12; 21, 22.
- the guide means 30 comprise at least one transverse guide rail 31, 32; 33, 34 with respect to which the conveyor 1, 12; 21, 22 is able to cooperate by sliding.

Description
DISPOSITIF DE PIVOTEMENT D'OBJETS PLATS DEVICE FOR PIVOTING FLAT OBJECTS
La présente invention concerne un dispositif permettant de faire pivoter des objets plats sur eux-mêmes, tout en les transportant de manière successive dans une direction donnée. L'invention trouve une application particulièrement avantageuse, mais non exclusive, dans le domaine de la fabrication des boîtes d'emballage en carton ondulé. Dans l'industrie de l'emballage, la fabrication de boîtes s'effectue traditionnellement en ligne, en pliant et en collant des découpes au moyen d'une machine communément appelée plieuse-colleuse. Une telle machine de traitement se présente habituellement sous la forme d'une succession de modules dans lesquelles sont répartis les différents agencements fonctionnels qui sont chargés de réaliser les multiples opérations élémentaires nécessaires à la confection des boîtes. Chaque module dispose de son propre système de transport des découpes, généralement des transporteurs à rouleaux ou à bandes, mais l'ensemble est agencé de manière à ce que le convoyage s'opère globalement de façon continue sur toute la longueur de la plieuse-colleuse. The present invention relates to a device for rotating flat objects on themselves, while transporting them successively in a given direction. The invention finds a particularly advantageous, but not exclusive, application in the field of the manufacture of corrugated packaging boxes. In the packaging industry, the manufacture of boxes is traditionally done online, by folding and gluing cuts by means of a machine commonly called folder-gluer. Such a processing machine is usually in the form of a succession of modules in which are distributed the various functional arrangements which are responsible for performing the multiple elementary operations necessary for making boxes. Each module has its own transport system for cuts, usually roller or belt conveyors, but the assembly is arranged in such a way that the conveying is effected globally continuously over the entire length of the folder-gluer. .
La fabrication de boîtes complexes requiert des opérations de pliage et de collage au niveau des quatre côtés des découpes. Pour que ces opérations puissent être effectuées en un seul passage dans la plieuse-colleuse, il s'avère indispensable de modifier l'orientation des découpes au cours du processus de fabrication des boîtes. C'est la raison pour laquelle des dispositifs de pivotement destinés à être intégrés au sein même des plieuses-colleuses, et capables de tourner à plat toutes les découpes qui les traversent durant leur convoyage ont été développés. The manufacture of complex boxes requires folding and gluing operations at the four sides of the cutouts. So that these operations can be performed in a single pass in the folder-gluer, it is essential to change the orientation of the cuts during the box manufacturing process. This is the reason why pivoting devices intended to be integrated within the folder-gluers, and able to turn flat all cuts that pass through during their conveying have been developed.
Etat de la technique State of the art
Parmi les dispositifs de pivotement connus de l'état de la technique, on distingue ceux qui mettent en œuvre deux convoyeurs placés côte à côte, parallèlement à la direction de convoyage des découpes. Ainsi positionnés, ces convoyeurs sont en mesure de supporter conjointement chaque découpe durant son convoyage. Et comme ils sont par ailleurs animés de vitesses différentes, ils ont naturellement tendance à faire translater chaque découpe tout en la faisant tourner sur elle-même. L'ensemble est généralement agencé de manière à ce que le pivotement à plat s'opère sur 90°.
Ce type de dispositif de pivotement présente toutefois l'inconvénient d'être avant tout adapté au carton compact, c'est-à-dire aux découpes de petits et moyens formats. Son efficacité s'avère en effet significativement réduite dès lors que les découpes sont de grandes tailles comme c'est souvent le cas avec le carton ondulé. La raison à cela est qu'avec une découpe dont au moins une des dimensions est bien supérieure à la largeur du dispositif de pivotement, au fur et à mesure du pivotement, certaines portions d'extrémités de la découpe finissent immanquablement par dépasser de part et d'autre des deux convoyeurs placés côte à côte. Ces derniers sont alors contraints de générer le pivotement en agissant uniquement sur la portion la plus centrale de la découpe, les portions d'extrémités ne faisant alors que suivre le mouvement. Or en pratique, vaincre une telle inertie avec de si faibles bras de levier s'avère particulièrement difficile. De plus, d'importants glissements apparaissent rapidement au niveau de la portion centrale de la découpe. L'ensemble de ces phénomènes fait qu'il devient dès lors quasi impossible de contrôler avec précision la rotation, et conséquemment de garantir la position finale de la découpe. Among the pivoting devices known from the state of the art, there are those which implement two conveyors placed side by side, parallel to the conveying direction of the cuts. Thus positioned, these conveyors are able to jointly support each cut during its conveyance. And since they are also animated by different speeds, they naturally tend to translate each cut while rotating it on itself. The assembly is generally arranged so that the flat pivoting operates on 90 °. This type of pivoting device, however, has the disadvantage of being primarily adapted to the compact cardboard, that is to say the cuts of small and medium formats. Its effectiveness is indeed significantly reduced when the cuts are large sizes as is often the case with corrugated cardboard. The reason for this is that with a cutout of which at least one of the dimensions is much greater than the width of the pivoting device, as and when swiveling, some portions of ends of the cut inevitably end up overtaking and other two conveyors placed side by side. The latter are then forced to generate pivoting by acting only on the most central portion of the cut, the end portions then only follow the movement. But in practice, overcoming such inertia with such weak arms is particularly difficult. In addition, large slips appear quickly at the central portion of the cut. All these phenomena makes it almost impossible to accurately control the rotation, and consequently to guarantee the final position of the cut.
Exposé de l'invention Presentation of the invention
Aussi, le problème technique à résoudre par l'objet de la présente invention, est de proposer un dispositif de pivotement d'une succession d'objets plats, comprenant deux convoyeurs qui sont disposés parallèlement l'un à l'autre afin de transporter chaque objet plat en le supportant conjointement, et qui sont à même d'être animés de vitesses différentes afin de faire pivoter à plat chaque objet tout en le transportant. Le dispositif de pivotement permet d'éviter les problèmes de l'état de la technique en étant parfaitement adapté au objets plats de grandes dimensions, et notamment à ceux réalisés en carton ondulé, tout en demeurant pleinement utilisable pour des objets de tailles standards voire de tailles réduites, qui plus est réalisés de carton compact. Also, the technical problem to be solved by the object of the present invention is to propose a device for pivoting a succession of flat objects, comprising two conveyors which are arranged parallel to one another in order to carry each flat object by supporting it jointly, and which are able to be animated with different speeds to rotate each object flat while carrying it. The pivoting device makes it possible to avoid the problems of the state of the art by being perfectly adapted to large flat objects, and in particular to those made of corrugated cardboard, while remaining fully usable for objects of standard sizes, even of reduced sizes, which is made of compact cardboard.
La solution au problème technique posé consiste, selon la présente invention, en ce que chaque convoyeur est monté réglable en position transversale de façon individuelle. The solution to the technical problem posed consists, according to the present invention, in that each conveyor is mounted adjustable in the transverse position individually.
La notion d'objet plat s'étend à tout objet aplati et de faible épaisseur, indépendamment de son contour, de son format ou du matériau qui le compose, tel qu'une feuille entière, une feuille prédécoupée, un ensemble de poses ou découpes attachées ponctuellement les unes aux autres, une pose ou découpe individuelle, une boîte pliée, etc. Par ailleurs, un tel objet plat peut être réalisé dans un matériau
quelconque, et notamment en papier, en carton compact, en carton ondulé, en matière plastique, etc. The concept of flat object extends to any flattened and thin object, regardless of its outline, its format or the material that composes it, such as an entire sheet, a pre-cut sheet, a set of poses or cuts punctually attached to each other, an individual pose or cut, a folded box, etc. Moreover, such a flat object can be made of a material and particularly in paper, compact cardboard, corrugated cardboard, plastic, etc.
De manière analogue, le terme convoyeur désigne dé façon générale n'importe quel dispositif capable de transporter un objet à plat, tel qu'un convoyeur à rouleaux, un convoyeur à bande, une juxtaposition de courroies de transport, un tapis de transport, ou à une combinaison de ces différents types de convoyeurs. Similarly, the term conveyor generally refers to any device capable of transporting a flat object, such as a roller conveyor, a conveyor belt, a juxtaposition of conveyor belts, a conveyor belt, or to a combination of these different types of conveyors.
Un convoyeur monté réglable en position transversale signifie que l'on peut modifier son positionnement en le déplaçant latéralement, et ceci indépendamment de la manière avec laquelle le déplacement est réalisé. C'est ainsi qu'un tel convoyeur peut par exemple être monté de manière amovible, c'est-à-dire qu'il est en mesure d'être démonté, déplacé puis remonté à une autre position. Mais le convoyeur peut également être monté mobile, c'est-à-dire qu'il est à même d'être déplacé entre une infinité de positions de fonctionnement, suite à une mise en mouvement suivant une trajectoire de déplacement préétablie. An adjustable mounted conveyor in the transverse position means that its positioning can be changed by moving it laterally, regardless of how the movement is made. Thus, such a conveyor can for example be removably mounted, that is to say, it is able to be disassembled, moved and reassembled to another position. But the conveyor can also be mounted movably, that is to say, it is able to be moved between an infinity of operating positions, following a set motion along a predetermined path of movement.
L'invention telle qu'ainsi définie présente l'avantage de disposer de convoyeurs dont la position est modifiable, mais surtout dont l'écartement relatif est ajustable. En effet, comme chaque convoyeur peut être déplacé individuellement, il est possible de changer sa position indépendamment de celle de son homologue. Cela permet de faire varier la distance séparant les deux convoyeurs, indépendamment de leurs positionnements transversaux respectifs. Il devient dès lors possible d'ajuster cet écartement relatif, notamment en fonction de la taille des objets à traiter et/ou de leur disposition lorsqu'ils se présentent en amont du dispositif de pivotement. En pratique, des convoyeurs sont généralement éloignés lorsqu'il s'agit de traiter des objets de grands formats, ou des objets allongés se présentant dans le sens de leur longueur (Fig. 4). A contrario, les convoyeurs sont rapprochés quand il est question de traiter des objets de plus petits formats, ou des objets allongés se présentant dans le sens de leur largeur (Fig. 5). The invention as thus defined has the advantage of having conveyors whose position is modifiable, but especially whose relative spacing is adjustable. Indeed, as each conveyor can be moved individually, it is possible to change its position independently of that of its counterpart. This makes it possible to vary the distance separating the two conveyors, independently of their respective transverse positions. It then becomes possible to adjust this relative spacing, in particular according to the size of the objects to be treated and / or their disposition when they are upstream of the pivoting device. In practice, conveyors are generally remote when it comes to processing large format objects, or elongated objects in the direction of their length (Fig. 4). On the other hand, conveyors are close together when it comes to processing objects of smaller size, or elongated objects in the direction of their width (Fig. 5).
Les deux convoyeurs peuvent être déplacés non seulement ensemble afin de déporter transversalement l'action du dispositif de pivotement, mais aussi indépendamment l'un de l'autre afin d'adapter cette action aux spécificités des objets traités. En conséquence, un dispositif de pivotement conforme à l'invention s'avère compatible aussi bien avec les objets plats de grandes dimensions, et notamment ceux réalisés en carton ondulé, qu'avec les objets de tailles plus réduites, qui plus est réalisés de carton compact.
Brève description des dessins The two conveyors can be moved not only together to transversely deport the action of the pivot device, but also independently of each other to adapt this action to the specifics of the treated objects. Consequently, a pivoting device according to the invention is compatible both with flat objects of large dimensions, and in particular those made of corrugated cardboard, with objects of smaller sizes, which are made of cardboard compact.

Exposé détaillé des formes de réalisation préférées Detailed description of the preferred embodiments
La Fig. 1 illustre une plieuse-colleuse 100 dont la fonction est de plier et de coller une succession d'objets plats 101 en forme de découpes, en vue de fabriquer des boîtes pliantes en carton ondulé. Dotée d'une structure modulaire, cette plieuse- colleuse 100 est classiquement composée d'un margeur 110, d'un module d'alignement 120, d'un premier module de pliage 130, d'un module de précassage 140, d'un module d'encollage 150, d'un second module de pliage 160, d'un module de transfert 170 et d'un module de réception 180. Ces différents éléments étant parfaitement connus de l'état de la technique, ne sont pas décrits en détail, tant structurellement que fonctionnellement. Fig. 1 illustrates a folder-gluer 100 whose function is to fold and glue a succession of flat objects 101 in the form of blanks, in order to manufacture corrugated cardboard folding boxes. With a modular structure, this folder-gluer 100 is conventionally composed of a feeder 110, an alignment module 120, a first folding module 130, a precasement module 140, a gluing module 150, a second folding module 160, a transfer module 170 and a receiving module 180. These various elements being perfectly known from the state of the art, are not described in FIG. detail, both structurally and functionally.
La Fig. 1 montre en outré que la plieuse-colleuse 100 est également équipée d'une unité de pivotement 1 qui est implantée entre le premier module de pliage 130 et le module de précassage 140. Ainsi positionnée, cette unité de pivotement 1 est chargée de tourner à plat chaque découpe 101 tout en la transportant du premier module de pliage 130 au module de précassage 140.
Ainsi qu'on peut le voir plus clairement sur la Fig. 2, l'unité de pivotement 1 est composée de deux dispositifs de pivotement 10 et 20 qui sont disposés l'un à la suite de l'autre suivant la direction de convoyage. Fig. 1 shows in addition that the folder-gluer 100 is also equipped with a pivoting unit 1 which is located between the first folding module 130 and the precasement module 140. Thus positioned, this pivoting unit 1 is responsible for turning to flatten each blank 101 while transporting it from the first folding module 130 to the precuring module 140. As can be seen more clearly in FIG. 2, the pivot unit 1 is composed of two pivoting devices 10 and 20 which are arranged one after the other in the conveying direction.
De manière particulièrement avantageuse, les dispositifs de pivotement 10 et 20 sont disposés de façon sensiblement adjacente. Cette caractéristique signifie qu'ils sont placés directement l'un à la suite de l'autre, et qu'ils agissent par conséquent de manière directement successive. Cela sous-entend qu'aucun dispositif intermédiaire ou espace n'est présent entre les deux, ce qui permet d'optimiser l'action cumulée des deux dispositifs de pivotement 10 et 20 successifs. Particularly advantageously, the pivoting devices 10 and 20 are arranged substantially adjacent. This characteristic means that they are placed directly one after the other, and that they therefore act in a directly successive manner. This implies that no intermediate device or space is present between the two, which makes it possible to optimize the cumulative action of the two successive pivoting devices 10 and 20.
Conformément à une autre caractéristique avantageuse, mais non représentée sur les différentes figures, l'unité de pivotement 1 peut comporter en outre un convoyeur d'entrée qui est placé directement en amont des dispositifs de pivotement successifs 10 et 20, et qui est en mesure de transporter chaque découpe 101 uniquement en le soutenant par-dessous. According to another advantageous characteristic, but not shown in the various figures, the pivot unit 1 may further comprise an input conveyor which is placed directly upstream of the successive pivoting devices 10 and 20, and which is able to to transport each cut 101 only by supporting it from below.
La présence d'un tel convoyeur d'entrée permet de transporter chaque découpe The presence of such an input conveyor makes it possible to transport each cutout
101 sans la maintenir fermement, contrairement à ce qui se passe avec un convoyeur classique de plieuse-colleuse, qui associe généralement un transporteur inférieur et un transporteur supérieur en position superposée. Ici, le convoyeur d'entrée consiste en quelque sorte en un simple transporteur inférieur sur lequel repose chaque découpe 101. L'absence d'un transporteur supérieur garantit une certaine mobilité à la découpe 101 , dans le plan de cette dernière. Cette liberté de déplacement permet alors avantageusement de débuter très tôt le pivotement de la découpe 101 , c'est-à-dire dès qu'elle arrive sur les premiers convoyeurs 11 et 12. 101 without holding it firmly, unlike what happens with a conventional folder-gluer conveyor, which generally associates a lower conveyor and an upper conveyor in a superimposed position. Here, the input conveyor is in a way a simple lower conveyor on which rests each cut 101. The absence of an upper carrier ensures a certain mobility to the cut 101 in the plane of the latter. This freedom of movement then advantageously makes it possible to start very early the pivoting of the blank 101, that is to say as soon as it arrives on the first conveyors 11 and 12.
Dans ce mode particulier de réalisation, choisi uniquement à titre d'exemple, les deux dispositifs de pivotement 10 et 20 composant l'unité de pivotement sont sensiblement identiques. Chacun d'entre eux comprend en effet deux convoyeurs 1 1 , 12; 21 , 22 qui sont disposés parallèlement l'un à l'autre afin de transporter chaque découpe 101 en le supportant conjointement, et qui sont à même d'être animés de vitesses différentes afin de faire pivoter à plat chaque découpe 101 tout en le transportant. In this particular embodiment, chosen solely by way of example, the two pivoting devices 10 and 20 composing the pivoting unit are substantially identical. Each of them comprises two conveyors 11, 12; 21, 22 which are arranged parallel to each other in order to transport each blank 101 by supporting it together, and which are able to be driven at different speeds in order to flatten each blank 101 while transporting it .
Conformément à l'objet de la présente invention, chaque convoyeur 11 , 12; 21 , 22 est monté réglable en position transversale de façon individuelle. According to the object of the present invention, each conveyor 11, 12; 21, 22 is individually adjustable in the transverse position.
Selon une particularité de l'invention, chaque convoyeur 11, 12; 21 , 22 est monté mobile en déplacement transversal. Dans le cas présent, chaque convoyeur 11 , 12; 21 , 22 n'est donc pas simplement monté amovible entre quelques positions de
fonctionnement, mais il est monté mobile afin de pouvoir être déplacé rapidement et de pouvoir accéder à une infinité de position de fonctionnement. According to a feature of the invention, each conveyor 11, 12; 21, 22 is movably mounted in transverse displacement. In the present case, each conveyor 11, 12; 21, 22 is not simply mounted removably between a few positions of operation, but it is mounted mobile so that it can be moved quickly and can access an infinity of operating position.
De manière particulièrement avantageuse, la mobilité transversale de chaque convoyeur 11 , 12; 21 , 22 s'exerce suivant un mouvement de translation linéaire. L'intérêt de ce type de mouvement est d'être particulièrement facile à guider et à générer. Cela permet de simplifier structurellement chaque dispositif de pivotement 10 et 20, et donc d'améliorer sa fiabilité tout en baissant son prix de revient. Particularly advantageously, the transverse mobility of each conveyor 11, 12; 21, 22 is exercised in a linear translational motion. The interest of this type of movement is to be particularly easy to guide and generate. This makes it possible to structurally simplify each pivoting device 10 and 20, and thus to improve its reliability while lowering its cost price.
D'ailleurs, et selon une autre particularité de l'invention, chaque dispositif de pivotement 10 et 20 est doté de moyens de guidage 30 qui sont en mesure de guider le déplacement transversal de chaque convoyeur 11 , 12; 21, 22. Moreover, and according to another feature of the invention, each pivoting device 10 and 20 is provided with guide means 30 which are able to guide the transverse displacement of each conveyor 11, 12; 21, 22.
De manière particulièrement avantageuse, pour chaque convoyeur 1 1 , 12; 21 , 22, les moyens de guidage 30 comportent au moins un rail de guidage transversal 31 , 32; 33, 34 par rapport auquel le convoyeur 1 , 12; 21 , 22 est apte à coopérer par coulissement. Particularly advantageously, for each conveyor January 1, 12; 21, 22, the guide means 30 comprise at least one transverse guide rail 31, 32; 33, 34 with respect to which the conveyor 1, 12; 21, 22 is able to cooperate by sliding.
Dans cet exemple de réalisation, et conformément aux Figs. 2 et 3, chaque dispositif de pivotement 10 et 20 repose sur un bâti 13, 23 qui est essentiellement composé de deux parois latérales verticales 14, 15; 24, 25 qui sont reliées par deux traverses horizontales 16, 17; 26, 27. Chaque convoyeur 11 , 12; 21 , 22 se présente sous la forme d'un convoyeur à rouleaux qui s'étend longitudinalement, et qui est monté transversalement coulissant par rapport à son bâti 13, 23, par l'intermédiaire de deux rails de guidage transversaux 31 , 32, 33, 34 qui sont fixés respectivement sur les deux traverses 16, 17; 26, 27. Pour d'évidentes raisons de simplicité, les deux convoyeurs 11 , 12; 21 , 22 de chaque dispositif de pivotement 10 et 20 coopèrent avec la même paire de rails de guidage 31 , 32; 33, 34. In this embodiment, and in accordance with FIGS. 2 and 3, each pivoting device 10 and 20 rests on a frame 13, 23 which is essentially composed of two vertical side walls 14, 15; 24, 25 which are connected by two horizontal crosspieces 16, 17; 26, 27. Each conveyor 11, 12; 21, 22 is in the form of a roller conveyor which extends longitudinally, and which is mounted transversely sliding relative to its frame 13, 23, by means of two transverse guide rails 31, 32, 33 34 which are respectively fixed on the two crosspieces 16, 17; 26, 27. For obvious reasons of simplicity, the two conveyors 11, 12; 21, 22 of each pivoting device 10 and 20 cooperate with the same pair of guide rails 31, 32; 33, 34.
Même si ce n'est pas le cas dans le mode particulier de réalisation choisi pour illustrer l'invention, chaque dispositif de pivotement 10 et 20 peut être avantageusement pourvu de moyens de verrouillage capables de bloquer la mobilité transversale de chaque convoyeur 1 1 , 12; 21 , 22. Bien entendu, les moyens de verrouillage en question peuvent être de tout type connu, comme par exemple une simple vis de blocage. Even if this is not the case in the particular embodiment chosen to illustrate the invention, each pivoting device 10 and 20 may advantageously be provided with locking means capable of blocking the transverse mobility of each conveyor 1 1, 12 ; Of course, the locking means in question can be of any known type, such as for example a simple locking screw.
A défaut, et selon une autre particularité de l'invention, chaque dispositif de pivotement 10 et^ 20 dispose de moyens d'entraînement 40 qui sont à même d'entraîner chaque convoyeur 11 , 12; 21 , 22 en déplacement transversal. Ces moyens d'entraînement 40 sont avant tout destinés à contrôler avec précision le déplacement de chaque convoyeur 11 , 12; 21 , 22. Mais ici, ils jouent aussi de manière avantageuse le rôle de moyens de verrouillage tels que précédemment définis. Ces moyens
d'entraînement 40 peuvent par ailleurs être motorisés ou manuels, selon le degré de sophistication que l'on désire conférer aux dispositifs de pivotement 10 et 20. Otherwise, and according to another feature of the invention, each pivoting device 10 and ^ 20 has drive means 40 which are able to drive each conveyor 11, 12; 21, 22 in transverse displacement. These drive means 40 are primarily intended to accurately control the movement of each conveyor 11, 12; 21, 22. But here, they also advantageously play the role of locking means as previously defined. These means drive 40 can also be motorized or manual, depending on the degree of sophistication that it is desired to provide to the pivoting devices 10 and 20.
Dans cet exemple de réalisation, les moyens d'entraînement 40 se présentent pour chaque convoyeur 1 , 12; 21 , 22, sous la forme d'un classique système de transmission 41 , 42 de type écrou et vis sans fin. Ce dernier n'est pas décrit en détail ici, compte tenu du fait qu'il est parfaitement connu de l'état de la technique. Sur la Fig. 3, les deux systèmes de transmission 41 et 42 sont visibles, et sont associés aux deux convoyeurs 11 et 12 du dispositif de pivotement 10. In this embodiment, the drive means 40 are for each conveyor 1, 12; 21, 22, in the form of a conventional transmission system 41, 42 type nut and worm. The latter is not described in detail here, given that it is perfectly known from the state of the art. In FIG. 3, the two transmission systems 41 and 42 are visible, and are associated with the two conveyors 11 and 12 of the pivot device 10.
Selon une autre particularité de l'invention visible sur la Fig. 2, le dispositif de pivotement comprend des moyens de support 50 qui sont en mesure de soutenir, tout en la laissant glisser, au moins une portion de chaque découpe 101 qui n'est pas supportée par les convoyeurs 11 , 12; 21 , 22. According to another feature of the invention visible in FIG. 2, the pivoting device comprises support means 50 which are able to support, while allowing it to slide, at least a portion of each blank 101 which is not supported by the conveyors 11, 12; 21, 22.
De manière particulièrement avantageuse, les moyens de support 50 comportent au moins une glissière 51 , 52, 53 qui est montée de façon amovible le long d'un des côtés d'un des convoyeurs 11 , 12; 21 , 22, et qui s'étend de façon sensiblement longitudinale dans le plan du convoyeur 11 , 12; 21 , 22. Particularly advantageously, the support means 50 comprise at least one slideway 51, 52, 53 which is removably mounted along one of the sides of one of the conveyors 11, 12; 21, 22, and extending substantially longitudinally in the plane of the conveyor 11, 12; 21, 22.
Dans cet exemple de réalisation, seul le dispositif de pivotement 20 est équipé de telles glissières 51 , 52 et 53. Deux glissières latérales 51 et 53 sont placées respectivement au niveau des bords externes des convoyeurs 21 et 22, ainsi qu'une glissière centrale 52 qui est positionnée le long du bord interne du convoyeur 21. In this exemplary embodiment, only the pivoting device 20 is equipped with such slides 51, 52 and 53. Two lateral slides 51 and 53 are placed respectively at the outer edges of the conveyors 21 and 22, as well as a central slide 52. which is positioned along the inner edge of the conveyor 21.
Selon une autre particularité de l'invention, qui est liée au fait que les découpes 101 constituent des objets plats de faible masse spécifique, chaque dispositif de pivotement 10 et 20 est doté de moyens de plaquage 60 qui sont chargés de plaquer chaque découpe 101 contre chaque convoyeur 1 1 , 12; 21 , 22. According to another feature of the invention, which is related to the fact that the cuts 101 are flat objects of low specific mass, each pivoting device 10 and 20 is provided with plating means 60 which are responsible for pressing each blank 101 against each conveyor 1 1, 12; 21, 22.
De manière particulièrement avantageuse, chaque convoyeur 11 , 12; 21 , 22 coopère avec des moyens de plaquage 60 qui lui sont propres. Cette caractéristique est avant tout destinée à ne pas perturber la mobilité transversale de chaque convoyeur 11 , 12; 21 , 22. Mais elle permet également d'activer de façon sélective, et/ou dé faire fonctionner de façon différenciée, les différents moyens de plaquage 60 qui sont respectivement associés aux différents convoyeurs 11 , 12; 21 , 22. Particularly advantageously, each conveyor 11, 12; 21, 22 cooperates with plating means 60 which are specific to it. This characteristic is primarily intended not to disturb the transverse mobility of each conveyor 11, 12; 21, 22. However, it also makes it possible to selectively activate, and / or operate in a differentiated manner, the different plating means 60 which are respectively associated with the different conveyors 11, 12; 21, 22.
Conformément à une autre caractéristique avantageuse, pour chaque convoyeur 11 , 12; 21 , 22, les moyens de plaquage 60 sont pourvus d'au moins un organe d'aspiration 61 qui sont à même de générer une aspiration à travers le convoyeur. According to another advantageous characteristic, for each conveyor 11, 12; 21, 22, the plating means 60 are provided with at least one suction member 61 which are able to generate a suction through the conveyor.
La Fig. 3 montre que dans cet exemple de réalisation, chaque convoyeur 1 , 12; 21 , 22 est associé à trois organes d'aspiration 61 sensiblement identiques. Chaque organe d'aspiration 61 se compose d'un caisson 62 qui prend place directement sous
les rouleaux 11a du convoyeur 11 , et qui est relié à une pompe d'aspiration 63 par l'intermédiaire d'une tubulure 64. Fig. 3 shows that in this embodiment, each conveyor 1, 12; 21, 22 is associated with three substantially identical suction members 61. Each suction member 61 consists of a box 62 which takes place directly under the rollers 11a of the conveyor 11, and which is connected to a suction pump 63 via a pipe 64.
L'invention concerne plus généralement toute machine de pliage et de collage 100 d'une succession d'objets plats, qui comporte au moins un dispositif de pivotement 10 et 20 tel que précédemment décrit. The invention more generally relates to any folding and gluing machine 100 of a series of flat objects, which comprises at least one pivoting device 10 and 20 as previously described.
De la même manière, l'invention est également relative à toute machine de pliage et de collage 100 d'une succession d'objets plats, qui comprend au moins une unité de pivotement 1 telle que précédemment décrite.
In the same way, the invention also relates to any folding and gluing machine 100 of a succession of flat objects, which comprises at least one pivoting unit 1 as previously described.
