Description

La présente invention se rapporte à un dispositif d'alimentation pour matériau en bande, comprenant une broche montée pivotante dans un bâti et reliée à un moteur d'entraínement. Cette invention se rapporte également à un module d'alimentation comprenant au moins deux dispositifs d'alimentation.The present invention relates to a supply device for strip material, comprising a spindle pivotally mounted in a frame and connected to a drive motor. This invention relates also to a power module comprising at least two feeding devices.

Il existe des domaines dans lesquels il est utile de pouvoir alimenter un processus de fabrication avec différents matériaux en bandes dont les longueurs à fournir au cours de ce processus peuvent varier sensiblement entre les différents matériaux, cette longueur étant fonction de la quantité de matériau en bande utilisé. Par conséquent, si l'on ne désire fournir que les longueurs nécessaires au processus de fabrication pour utiliser le matériau en bande de façon optimale, il faut pouvoir entraíner les broches portant ces matériaux en bandes à des vitesses ou à des intervalles différents. On rencontre en particulier ce problème dans la fabrication de matériau en feuille dont la surface est sélectivement métallisée à l'aide de feuilles de métal rapporté. Cette technique est couramment utilisée en particulier pour l'impression et le gaufrage de découpes de papier ou de carton pour la fabrication d'emballages, notamment pour articles de luxe.There are areas in which it is useful to be able feeding a manufacturing process with different strip materials whose lengths to be supplied during this process may vary substantially between different materials, this length being a function the amount of strip material used. Therefore, if one does not want to supply only the lengths necessary for the manufacturing process to use the strip material optimally, you must be able to drive the pins carrying these materials in strips at speeds or at different intervals. This problem is encountered in particular in the manufacture of sheet material whose surface is selectively metallized with added metal sheets. This technique is commonly used especially for printing and embossing paper or cardboard cutouts for the manufacture of packaging, especially for luxury items.

Il est évidemment possible de disposer chaque rouleau de matériau en bande sur une broche indépendante, entraínée par son propre moteur, mais la multiplication de ces broches pose des problèmes d'encombrement. Par ailleurs, si les broches destinées à l'alimentation des matériaux en bande doivent s'étendre sur toute la largeur de travail de la machine, pour permettre de distribuer sélectivement le matériau en bande aux endroits désirés sur les découpes de papier ou de carton, la largeur du matériau en bande est pratiquement toujours sensiblement inférieure à celle de la largeur de travail de la machine correspondant elle-même plus ou moins à celle des découpes de papier ou de carton. Par conséquent, le plus souvent seule une faible partie de la longueur d'une broche d'entraínement est utilisée, ou si on dispose plusieurs bobines de matériau en bande côte à côte sur la même broche d'entraínement, la quantité de matériau en bande distribué par cette broche doit être réglée sur le matériau en bande le plus utilisé, augmentant la perte de l'autre matériau en bande disposé sur cette même broche.It is obviously possible to arrange each roll of strip material on an independent spindle, driven by its own motor, but the multiplication of these pins poses problems of space. Furthermore, if the pins intended for supplying the strip material should extend over the entire working width of the machine, to allow to selectively distribute the strip material where desired on paper or cardboard cutouts, the width of the strip material is almost always substantially less than that of the working width of the corresponding machine itself more or less than that of paper or cardboard cutouts. Therefore, the more often only a small part of the length of a spindle is used, or if there are several coils of material in a strip side by side on the same drive spindle, the amount of strip material distributed by this spindle must be set to the most used strip material, increasing loss of other material in a strip arranged on this same pin.

Le but de la présente invention est de remédier, au moins en partie, aux inconvénients susmentionnés.The object of the present invention is to remedy, at least by part, to the aforementioned drawbacks.

A cet effet, cette invention a pour objet un dispositif d'alimentation pour matériau en bande dans lequel ladite broche est divisée longitudinalement en deux tronçons distincts montés rotativement indépendamment l'un par rapport à l'autre, et en ce qu'il comprend deux mécanismes d'entraínement respectifs de ces deux tronçons reliés à une extrémité commune de ladite broche, ledit tronçon adjacent à ladite extrémité commune présentant la forme d'un élément tubulaire monté pivotant sur un arbre le traversant axialement et cet élément tubulaire est solidaire de moyens pour le relier à l'un desdits mécanismes d'entraínement, l'extrémité dudit arbre adjacente à ladite extrémité commune de ladite broche comprenant des moyens pour la relier à l'autre desdits mécanismes d'entraínement, tandis que l'autre extrémité dudit arbre est solidaire dudit second tronçon.To this end, the subject of this invention is a device feed for strip material in which said spindle is divided longitudinally into two separate sections rotatably mounted independently of each other, and in that it comprises two respective drive mechanisms of these two sections connected to a common end of said spindle, said section adjacent to said common end in the form of a mounted tubular member pivoting on a shaft axially passing through it and this tubular element is secured to means for connecting it to one of said mechanisms drive, the end of said shaft adjacent to said end common of said pin comprising means for connecting it to the other said drive mechanisms, while the other end of said shaft is integral with said second section.

Bien évidemment, plusieurs de ces dispositifs peuvent être disposés côte à côte sur la même machine, formant ainsi un module d'alimentation suivant le nombre maximum de bandes différentes prévu pour une machine donnée, chaque dispositif pouvant distribuer deux bandes différentes à des vitesses ou à des intervalles de temps indépendants. Dans ce cas, on peut avantageusement associer des dispositifs dont les broches respectives présentent des tronçons dont les longueurs varient d'une broche à l'autre, afin de permettre de disposer et de positionner des bandes de différentes largeurs, dans différentes positions par rapport à la largeur de travail de la machine.Obviously, several of these devices can be arranged side by side on the same machine, thus forming a module supply according to the maximum number of different bands provided for a given machine, each device being able to distribute two different bands at speeds or time intervals independent. In this case, it is advantageous to associate devices whose respective pins have sections whose lengths vary from one spindle to another, in order to provide and to position strips of different widths, in different positions in relation to the working width of the machine.

Par conséquent, non seulement ce dispositif permet l'entraínement continu ou intermittent de broches coaxiales à fréquence et/ou à vitesses différentes, mais il permet de varier la longueur des différents tronçons et d'offrir ainsi une grande flexibilité quant à la répartition des différentes bandes de matériau distribuées.Therefore, not only does this device allow continuous or intermittent drive of frequency coaxial spindles and / or at different speeds, but it allows the length of the different sections and thus offer great flexibility as to the distribution of the different strips of material distributed.

D'autres particularités et avantages de cette invention apparaítront au cours de la description qui va suivre faite à l'aide du dessin annexé qui illustre, schématiquement et à titre d'exemple, une forme d'exécution du dispositif moteur pour broche d'entraínement.

    • La figure 1 illustre un module d'alimentation de matériau en bande d'une machine pour l'impression sur papier ou carton de motifs à l'aide de feuilles métalliques ou de substrats de plastique métallisé, notamment pour la réalisation d'impression dans le domaine de l'emballage.Figure 1 illustrates a material supply module in machine band for printing patterns on paper or cardboard using metallic foils or metallized plastic substrates, especially for printing in the field of packaging.

    Dans l'exemple illustré, le module d'alimentation comporte trois dispositifs d'alimentation 1, 2 et 3. Chaque dispositif comporte une broche 11, 12, respectivement 13 divisée longitudinalement en deux tronçons 11a, 11b; 12a, 12b; respectivement 13a, 13b. Les premiers tronçons 11a, 12a, 13a sont constitués par des éléments tubulaires montés rotativement sur des arbres 4, 5, respectivement 6 par l'intermédiaire de paliers à billes 7 disposés à une extrémité et de paliers à aiguilles 8 disposés à l'autre extrémité.In the example illustrated, the power module has three feeding devices 1, 2 and 3. Each device has a pin 11, 12, respectively 13 divided longitudinally into two sections 11a, 11b; 12a, 12b; respectively 13a, 13b. The first sections 11a, 12a, 13a consist of tubular elements rotatably mounted on shafts 4, 5, respectively 6 by means of ball bearings 7 arranged at one end and needle bearings 8 arranged at the other end.

    Une extrémité de chaque arbre 4, 5, 6 est reliée à un moteur d'entraínement 8, 9 respectivement 10, par exemple, par un système accouplement élastique 31, 32, respectivement 33, tandis que les extrémités respectives opposées de ces arbres 4, 5, 6 sont solidaires des seconds tronçons 11b, 12b, respectivement 13b desdites broches 11, 12 respectivement 13.One end of each shaft 4, 5, 6 is connected to a motor 8, 9 respectively 10, for example, by a system elastic coupling 31, 32, respectively 33, while the respective opposite ends of these shafts 4, 5, 6 are integral with the second sections 11b, 12b, respectively 13b of said pins 11, 12 respectively 13.

    Comme on peut le constater sur le dessin, ces second tronçons 11b, 12b, 13b sont également constitués par des éléments tubulaires dont une des extrémités est chassée sur une extrémité des arbres respectifs 4, 5, 6. Un organe de pivotement 111b, 112b, 113b est chassé dans les autres extrémités de ces seconds tronçons 11b, 12b, 13b.As can be seen in the drawing, these second sections 11b, 12b, 13b are also formed by elements tubular, one end of which is driven out on one end of the respective shafts 4, 5, 6. A pivoting member 111b, 112b, 113b is driven into the other ends of these second sections 11b, 12b, 13b.

    Les deux extrémités des broches 11, 12, 13 sont pivotées dans deux portions d'un bâti 14 par l'intermédiaire de paliers à billes 15. A une extrémité de ces broches 11, 12, 13, ce sont les extrémités des arbres respectifs 4, 5, 6 qui sont montée pivotantes dans les paliers à billes 15 respectifs, tandis qu'à l'autre extrémité de ces mêmes broches 11, 12, 13, ce sont les organes de pivotement 111b, 112b et 113b qui sont pivotés dans ces paliers à billes 15 respectifs.The two ends of pins 11, 12, 13 are pivoted in two portions of a frame 14 by means of ball bearings 15. At one end of these pins 11, 12, 13, these are the ends of the shafts respective 4, 5, 6 which are pivotally mounted in the ball bearings 15 respective, while at the other end of these same pins 11, 12, 13, it is the pivoting members 111b, 112b and 113b which are pivoted in these respective ball bearings 15.

    Comme on peut le constater sur la figure 1, les trois broches 11, 12, 13 ont la même longueur, mais sont divisées en tronçons 11a, 11b; 12a, 12b; 13a, 13b, dont les longueurs respectives varient d'une broche à l'autre. Cette variation de longueur entre les tronçons homologues des différentes broches 11, 12, 13, a pour but d'offrir des broches d'alimentations de différentes longueurs dans chacune des deux moitiés de la longueur des dispositifs d'alimentation 1, 2 et 3 du module d'alimentation. Grâce à cette disposition, l'utilisateur dispose de trois longueurs de tronçons de broches différentes 11a, 12a, 13a, respectivement 11b, 12b, 13b, pour chaque moitié de la longueur du module d'alimentation, permettant de fixer sur ces tronçons des rouleaux de matériaux en bandes de différentes largeurs. Cet éventail de dimensions donne un large choix en fonction des besoins.As can be seen in Figure 1, the three pins 11, 12, 13 have the same length, but are divided into sections 11a, 11b; 12a, 12b; 13a, 13b, the respective lengths of which vary from spindle to the other. This variation in length between the homologous sections of different pins 11, 12, 13, aims to offer pins feeds of different lengths in each of the two halves the length of the supply devices 1, 2 and 3 of the module feed. Thanks to this arrangement, the user has three lengths of different spindle sections 11a, 12a, 13a, respectively 11b, 12b, 13b, for each half of the length of the feed module, for fixing rollers on these sections of strip materials of different widths. This range of dimensions gives a wide choice depending on the needs.

    Alors que les tronçons 11b, 12b, 13b sont entraínés par les arbres 4, 5, respectivement 6 en prise avec les moteurs d'entraínement 8, 9, et 10, les tronçons 11a, 12a, 13a sont solidaires de pignons cannelés 16, 17, respectivement 18. Comme illustré en particulier sur la figure 3, chacun de ces pignon 16, 17 et 18 est relié par une courroie crantée 19, 20, respectivement 21 à un pignon cannelé 22, 23, respectivement 24, calé sur l'arbre de sortie d'un moteur d'entraínement 25, 26, respectivement 27. Des galets presseurs 28, 29, respectivement 30 servent à mettre les courroies 19, 20, 21 sous une pré-tension appropriée.While the sections 11b, 12b, 13b are driven by the shafts 4, 5, respectively 6 engaged with the drive motors 8, 9, and 10, the sections 11a, 12a, 13a are integral with grooved pinions 16, 17, respectively 18. As illustrated in particular in FIG. 3, each of these pinions 16, 17 and 18 is connected by a toothed belt 19, 20, respectively 21 to a grooved pinion 22, 23, respectively 24, wedged on the output shaft of a drive motor 25, 26, respectively 27. Pressure rollers 28, 29, respectively 30 serve to put the belts 19, 20, 21 under an appropriate pre-tension.

    Etant donné que chacun des deux tronçons 11a, 11b; 12a, 12b; 13a, 13b des broches 11, 12, respectivement 13 est entraíné par un moteur indépendant, chacun de ces tronçons peut être entraíné à des intervalles, pendant des durées et à des vitesses, indépendants de tout autre tronçon, que celui-ci appartienne à une autre broche ou à la même broche, par une programmation appropriée des moteurs d'entraínements 8, 9, 10, 25, 26, 27. La programmation de ces moteurs d'entraínement ne fait pas partie de la présente invention et n'est pas nécessaire à sa compréhension, de sorte qu'elle ne sera pas décrite ici.Since each of the two sections 11a, 11b; 12a, 12b; 13a, 13b of pins 11, 12, respectively 13 is driven by a independent motor, each of these sections can be driven to intervals, for durations and at speeds, independent of everything another section, whether this one belongs to another spindle or to the same spindle, by appropriate programming of the drive motors 8, 9, 10, 25, 26, 27. The programming of these drive motors does not is not part of the present invention and is not necessary for its understanding, so it will not be described here.

    Bien entendu, le module d'alimentation décrit peut comporter un nombre de broches différent de trois et est fonction des applications envisagées. Toutefois, dans le cas d'un module d'alimentation pour une machine utilisée pour l'impression d'empreintes métallisées sur des feuilles ou des découpes de papier ou de carton, notamment en vue de la confection d'emballage à partir de ces feuilles ou découpes, le module décrit permet de couvrir pratiquement toutes les combinaisons que l'on peut rencontrer dans la pratique.Of course, the power module described may include a number of pins other than three and depends on the applications considered. However, in the case of a power module for a machine used for printing metallic prints on sheets or cutouts of paper or cardboard, particularly for the purpose of packaging from these sheets or cutouts, the module described makes it possible to cover practically all the combinations which one can meet in practice.
