Description

La présente invention a pour objet un module de support et d'entraînement d'une matière en bande bobinée pour une machine la travaillant, notamment pour une machine destinée à l'utilisation de bandes métallisées pour la fabrication d'emballages.The present invention relates to a module for supporting and driving a wound strip material for a machine working, especially for a machine for the use of metallized strips for the manufacture of packaging.

Une telle machine est utilisée pour le gaufrage et le transfert par pression de portions de films, préférentiellement métalliques, issues de telles bandes sur un substrat de papier, de matière plastique ou de carton plus particulièrement. Ces opérations sont par exemple effectuées dans une machine équipée d'une presse à platine travaillant des éléments en plaque, tels que des feuilles de carton, pour l'estampage de motifs donnés. Ces motifs étant issus d'une bande métallisée conduite entre le plan de défilement des éléments en plaque et le sommier supérieur de la presse. Dans un mouvement vertical périodique, le sommier inférieur mobile va presser la bande métallisée contre chaque feuille de carton entre des clichés et des contreparties correspondantes pour y déposer la dorure en correspondance avec les motifs des clichés. Une fois le transfert réalisé, le sommier inférieur redescend et la feuille de carton estampée est retirée de la presse à platine pour laisser la place à une nouvelle feuille. Dans le même intervalle de temps, la bande métallisée est déplacée de façon à ce qu'une nouvelle surface vierge soit mise en correspondance avec les clichés. Le processus de découpage et de transfert de la bande peut alors être répété.Such a machine is used for the embossing and pressure transfer of portions of films, preferably metal, from such strips on a substrate of paper, plastic or cardboard more particularly. These operations are for example carried out in a machine equipped with a platen press working plate elements, such as cardboard sheets, for the stamping of given patterns. These patterns are derived from a metallized strip conducted between the scroll plane of the plate elements and the upper bed of the press. In a periodic vertical movement, the movable lower bed base will press the metallized strip against each sheet of cardboard between shots and corresponding counterparts to deposit the gilding in correspondence with the patterns of the pictures. Once the transfer is completed, the lower bed base descends and the stamped cardboard sheet is removed from the platen press to make room for a new sheet. In the same time interval, the metallized strip is moved so that a new virgin surface is mapped to the plates. The process of cutting and transferring the tape can then be repeated.

Une telle machine peut également être utilisée pour le découpage de feuilles de carton selon une suite d'opérations faites chacune dans une station adjacente. Cette suite d'opérations comprend généralement l'introduction de la feuille dans la presse, son découpage par des outils agencés sur la platine, l'éjection des déchets par des outils spécifiques et la réception en piles des éléments de feuille découpés. Afin d'optimiser les possibilités d'une telle machine, il est connu de pouvoir la transformer de façon à ce que la station initialement prévue pour le découpage devienne une station d'estampage de bandes métallisées par remplacement des outils de découpage en un dispositif d'estampage et par remplacement des outils de la station d'éjection en un dispositif de chargement et de déroulement des bobines de bandes métallisées. Une telle transformation est illustrée par la machine décrite dans le brevet EP 741'096 .Such a machine can also be used for cutting cardboard sheets according to a sequence of operations each made in an adjacent station. This series of operations usually includes the introduction of the sheet in the press, its cutting by tools arranged on the plate, the ejection of waste by specific tools and the receipt in stacks of cut sheet elements. In order to optimize the possibilities of such a machine, it is known to be able to transform it so that the station initially intended for cutting becomes a stamping station for metallized strips by replacing the cutting tools in a device for cutting. stamping and replacing the tools of the ejection station in a device for loading and unwinding the metallized strip coils. Such a transformation is illustrated by the machine described in the patent EP 741,096 .

L'agencement dans la station d'éjection d'un dispositif de chargement et de déroulement de bandes au sein d'une telle machine est décrit en détail dans le brevet EP 741'095 . Ce dispositif comprend notamment une paire de bras verticaux parallèles entre lesquels sont disposés des traverses servant de supports à une pluralité de bobines de bandes métallisées. Les largeurs de ces bandes étant typiquement de l'ordre de 5 à 20 cm. Il convient de relever que ces bandes métallisées portant des motifs, ou des bandes appelées bandes à diffraction, sont généralement réalisées en déposant, par impression, une couche décorative métallique sur un substrat constitué par un matériau flexible, par exemple un matériau plastique. De par leur fabrication, ces bandes métallisées comportent une fine ligne de raccord provenant du cliché cylindrique portant le motif à imprimer qui ne peut pas, à l'évidence, couvrir les 360° du cylindre porte-cliché. De ce fait, cette fine ligne de raccord apparaîtra à chaque tour du cylindre porte-cliché et il conviendra d'éviter que cette ligne de raccord entre en conflit avec l'un des motifs à estamper.The arrangement in the ejection station of a loading and unwinding device in such a machine is described in detail in the patent. EP 741'095 . This device comprises in particular a pair of parallel vertical arms between which are arranged cross supports for a plurality of metallized strip coils. The widths of these strips are typically of the order of 5 to 20 cm. It should be noted that these patterned metallized strips, or bands called diffraction bands, are generally made by depositing, by printing, a decorative metal layer on a substrate made of a flexible material, for example a plastic material. By their manufacture, these metallized strips have a thin line of connection from the cylindrical plate bearing the pattern to be printed which obviously can not cover the 360 ° of the forme cylinder. As a result, this thin connection line will appear at each turn of the forme cylinder and it will be necessary to prevent this connection line from conflicting with one of the patterns to be stamped.

De part la disposition transversale des axes de rotation des bobines par rapport à l'axe longitudinal de la machine, le déroulement des bandes se fait parallèlement au sens de défilement des feuilles à estamper. Le transport de ces bandes nécessite des moyens de déroulement et d'avance intermittents généralement constitués par des rouleaux contre lesquels les bandes sont pincées par des galets presseurs. L'entraînement motorisé de ces rouleaux permet l'avance intermittente de ces bandes. Suivant les profils de vitesse désirés, il peut y avoir plusieurs rouleaux d'avance qui permettent à chaque bande de bénéficier d'un entraînement indépendant. Lors de l'utilisation de bandes plus larges, il est également nécessaire de prévoir plusieurs galets presseurs par bande. Ces galets presseurs sont montés en coulissement sur des axes transversaux de façon à ce que leur positionnement puisse se faire en toute indépendance. Cependant, l'ensemble formé par le dispositif de chargement et de support des bobines, les rouleaux de renvois, les rouleaux d'entraînement, leur motorisation ainsi que les galets presseurs réglables en position nécessite la mise en oeuvre de travaux conséquents lorsqu'il s'agit d'aménager un tel dispositif au sein d'une machine de découpage en vue de sa transformation en une machine d'estampage. Ne pouvant pas être réalisés en temps masqués, ces travaux de transformation immobilisent la machine durant de longues heures et contribuent au renchérissement de la future production, principalement lors de petites séries.Due to the transverse arrangement of the axes of rotation of the coils with respect to the longitudinal axis of the machine, the unwinding of the strips is parallel to the direction of scrolling sheets to stamp. The transport of these strips requires means of unwinding and intermittent advance generally consist of rollers against which the strips are pinched by pressure rollers. The motorized drive of these rollers allows the intermittent advance of these bands. Depending on the desired speed profiles, there may be several advance rollers that allow each band to benefit from an independent drive. When using wider strips, it is also necessary to provide several pressure rollers per band. These pressure rollers are slidably mounted on transverse axes so that their positioning can be done independently. However, the assembly formed by the device for loading and supporting the coils, the return rollers, the drive rollers, their motorization and the pressure rollers adjustable in position requires the implementation of substantial work when it s is to arrange such a device in a cutting machine for its transformation into a stamping machine. Since they can not be made in masked time, these processing works immobilize the machine for long hours and contribute to the increase of the future production, mainly during small series.

Bien que la majorité des dorures déposées sur les emballages puissent être réalisées à partir de bandes de faible largeur, n'excédant généralement pas 30 cm, il est parfois nécessaire de recourir à des bandes métallisées de plus grande largeur, typiquement de l'ordre de 50 à 70 cm, ou à une pluralité de bandes plus étroites disposées côte à côte et dont la largeur totale cumulée avoisine cet ordre de grandeur.Although the majority of the gilding deposited on the packages can be made from strips of small width, generally not exceeding 30 cm, it is sometimes necessary to use metallized strips of greater width, typically of the order of 50 to 70 cm, or a plurality of narrower bands arranged side by side and whose total cumulative width is around this order of magnitude.

Or, l'utilisation de bobines de grande largeur pose des problèmes de manutention notamment. En raison du poids que représentent ces bobines, il n'est à l'évidence plus possible de les déplacer à bras d'homme pour les disposer dans la machine. Il convient donc de recourir à des moyens de levage comme des palans ou de petits véhicules aptes à déplacer aisément de lourdes charges. Cependant, la mise en place de telles bobines par ces moyens rend les manipulations en machine délicates, voire parfois même impossibles, soit par manque de place autour de la machine, soit en raison d'un accès impossible à l'intérieur de la machine non prévue pour de tels moyens.However, the use of large width reels poses handling problems in particular. Because of the weight that represent these coils, it is obviously no longer possible to move them to man's arms to arrange them in the machine. Lifting devices such as hoists or small vehicles that can move heavy loads easily should be used. However, the establishment of such coils by these means makes machine manipulations delicate, sometimes even impossible, either for lack of space around the machine, or because of an impossible access to the inside of the machine. provided for such means.

Le document US 4'341'586 décrit un dispositif de distribution d'une matière en bande pour l'emballage de gros rouleaux de papier afin de les protéger avant leur utilisation. La matière en bande destinée à cette emballage se trouve enroulée sur des bobines disposées entre les parois de deux bâtis adjacents. Ces bobines sont portées par leur moyeu sur des arbres qui sont soutenus en leurs extrémités directement entre les parois du bâti correspondant. Or, conformément à une telle disposition, l'agencement par exemple de trois bobines sur un tel arbre ne permet pas le retrait de la bobine centrale sans le retrait préalable d'une des bobines latérales.The document US 4,341,586 discloses a strip material dispensing device for packaging large rolls of paper to protect them prior to use. The strip material for this package is wound on coils disposed between the walls of two adjacent frames. These coils are carried by their hub on shafts which are supported at their ends directly between the walls of the corresponding frame. However, according to such a provision, the arrangement for example of three coils on such a shaft does not allow the removal of the central coil without the prior removal of one of the side coils.

Le but de la présente invention vise à remédier, au moins en partie, aux inconvénients précités en suggérant un nouveau module de support et d'entraînement d'une matière en bande pour une machine la travaillant. A ces fins, l'objet de la présente invention doit offrir un accès optimum pour le chargement et le déchargement de bobines, même de grandes tailles, par tout moyen conventionnel quel qu'il soit. La manutention de telles bobines ne doit ni être limitée ni rendue impossible par un espace voisin restreint ou par une voie d'accès impossible. L'objet de la présente invention doit également autoriser sa préparation en temps masqué afin de réduire autant que possible le temps d'immobilisation de la machine en cours de transformation. Il doit offrir une convertibilité rapide et conviviale de la machine de découpage en une machine d'estampage et inversement. Il doit également pouvoir offrir une plus grande flexibilité quant à l'agencement d'éventuels organes ou dispositifs optionnels, tels que, par exemple des organes de détection des lignes de raccord existant sur la bande métallisée,ou sur la bande à diffraction, dispositifs nécessitant des distances spatiales importantes. Enfin, il doit pouvoir être facilement adaptable aux machines de découpages n'ayant encore jamais été transformées en machines d'estampage.The object of the present invention is to remedy, at least in part, the aforementioned drawbacks by suggesting a new support module and drive a strip material for a machine working. For these purposes, the object of the present invention is to provide optimum access for loading and unloading coils, even large ones, by any conventional means. The handling of such reels should not be limited or made impossible by a nearby restricted space or by an impossible access route. The object of the present invention must also allow its preparation in masked time to reduce as much as possible the downtime of the machine during processing. He must offer a fast and user-friendly convertibility of the cutting machine into a stamping machine and vice versa. It must also be able to offer greater flexibility as to the arrangement of any optional members or devices, such as, for example, detecting members of connection lines existing on the metallised strip, or on the diffraction band, devices requiring important spatial distances. Finally, it must be easily adaptable to cutting machines that have never been converted into stamping machines.

Ces buts sont atteints grâce à la présente invention qui a pour objet un module de support et d'entraînement d'une matière en bande bobinée, conforme à ce qu'énonce la revendication 1.These objects are achieved by the present invention which relates to a support and training module a wound web material as set forth in claim 1.

  • La figure 1 est une vue en perspective de face du module de l'invention.
  • La figure 2 est une vue en perspective depuis l'arrière d'une partie de l'objet de l'invention illustrant un porte-bobine agencé sur une barre transversale, un dispositif d'entraînement associé ainsi qu'une chaîne cinématique préférée.
  • La figure 3 est une vue partielle et en perspective d'un détail d'une variante de l'illustration donnée à la figure 2.
  • La figure 4 est une vue simplifiée, en perspective de face, du module de l'invention.
The invention will be better understood from the study of a preferred embodiment, taken in a non-limiting manner and illustrated by the appended figures in which:
  • The figure 1 is a front perspective view of the module of the invention.
  • The figure 2 is a perspective view from the rear of a part of the object of the invention illustrating a reel holder arranged on a cross bar, an associated driving device and a preferred kinematic chain.
  • The figure 3 is a partial view in perspective of a detail of a variant of the illustration given to the figure 2 .
  • The figure 4 is a simplified view, in front perspective, of the module of the invention.

La figure 1 montre l'objet de la présente invention, vu depuis le devant, qui consiste en un module 1, indépendant, situé entièrement à l'extérieur d'une machine attenante non illustrée qui travaille une matière en bande. Il est donc prévu que ce module soit disposé hors de cette machine et hors de son axe longitudinal, préférentiellement à la hauteur de la station d'éjection normalement prévue dans toute machine de découpage performante. Cette station aura été transformée pour l'occasion en un espace agencé de rouleaux de renvois disposés par exemple à 45° par rapport à l'axe longitudinal de la machine. De ce fait, il est prévu que la ou les bandes issues de ce module 1 puissent entrer dans ladite machine par son côté, au travers d'une fenêtre ouverte dans l'une des parois latérales de son bâti, avant d'être déviées par lesdits rouleaux de renvois en repérage avec l'axe longitudinal de cette machine.The figure 1 shows the object of the present invention, seen from the front, which consists of a module 1, independent, located entirely outside an adjacent machine not shown that works a material band. It is therefore expected that this module is disposed out of this machine and out of its longitudinal axis, preferably at the height of the ejection station normally provided in any cutting machine performance. This station has been converted for the occasion into an arranged space of rollers of references arranged for example at 45 ° with respect to the longitudinal axis of the machine. Therefore, it is expected that the strip or strips from this module 1 can enter said machine by its side, through an open window in one of the side walls of its frame, before being deflected by said reference rolls in registration with the longitudinal axis of this machine.

Le module 1 comprend un bâti formé d'une embase 2 et de deux parois latérales 3, 4 constituant une structure portante 5 notamment pour une pluralité de bobines 6 desquelles est issue ladite matière en bande. Chaque bobine est soutenue par un porte-bobines 10 et est entraînée en rotation par au moins un dispositif d'entraînement 20.The module 1 comprises a frame formed of a base 2 and two side walls 3, 4 constituting a bearing structure 5, in particular for a plurality of coils 6 from which said strip material originates. Each coil is supported by a reel holder 10 and is rotated by at least one driving device 20.

Les figures 2 et 3 montrent plus en détail, depuis l'arrière, un des organes d'entraînement 20 ainsi que le porte-bobine 10 associé à ce dispositif. Ce porte-bobine se compose de deux flasques 11 qui permettent de soutenir la bobine 6 par son moyeu 7. Cette bobine est montée libre en rotation au moyen de flasques 11, chacun agencé sur un support 12. Ces supports sont fixés à leur tour sur une barre 15 porte-bobines au moyen d'organe de serrage 13, tels que des vis ou des poulets moletés par exemple. Les porte-bobines 10 sont ajustables le long de cette barre 15 qui, comme illustrée dans les figures 1 et 2, est préférentiellement de section carrée et est soutenue en ses extrémités par les parois 3 et 4 de la structure portante 5. Grâce à de tels porte-bobines 10 amovibles indépendamment les uns des autres, il est possible d'ajuster, de placer et de retirer aisément une bobine 6 du module 1 sans devoir déplacer d'autres bobines déjà mises en place.The Figures 2 and 3 show in more detail, from the rear, one of the drive members 20 and the spool holder 10 associated with this device. This spool holder consists of two flanges 11 which support the spool 6 by its hub 7. This spool is mounted free to rotate by means of flanges 11, each arranged on a support 12. These supports are in turn fixed on a reel bar 15 by means of clamping member 13, such as knurled screws or chickens for example. The reel carriers 10 are adjustable along the bar 15 which, as illustrated in FIGS. figures 1 and 2 , is preferably of square section and is supported at its ends by the walls 3 and 4 of the supporting structure 5. With such reel carriers 10 removable independently of each other, it is possible to adjust, place and easily remove a coil 6 from module 1 without having to move other coils already in place.

En référence aux figures 2 et 3, le dispositif d'entraînement 20 comprend deux joues 21, 22 entre lesquelles tourne une courroie 16, sans fin, mieux visible dans la figure 3. Cette courroie est disposée de manière à ce qu'elle soit toujours en contact avec une portion arrière de la circonférence extérieure de la bobine 6. Par frottement avec cette portion cylindrique, la bobine est entraînée en rotation par l'action de la courroie 16 et de ce fait, la matière en bande peut en être déroulée en vue de son utilisation dans une machine attenante, voire à l'inverse enroulée s'il elle provient de cette machine.With reference to Figures 2 and 3 , the driving device 20 comprises two cheeks 21, 22 between which turns a belt 16, endless, better visible in the figure 3 . This belt is arranged so that it is always in contact with a rear portion of the outer circumference of the coil 6. By friction with this cylindrical portion, the coil is rotated by the action of the belt 16 and of therefore, the web material may be unwound for use in an adjoining machine, or even rolled back if it comes from this machine.

Les joues 21, 22 sont maintenues entre elles par des entretoises 23 et permettent notamment l'agencement d'un organe d'entraînement 24 pour la mise en rotation de la courroie 16. Depuis cette organe d'entraînement, la courroie chemine respectivement autour d'un galet tendeur 25, puis autour d'une pluralité de galets de renvoi 26 dont un galet de renvoi inférieur 27 situé à l'extrémité inférieure du parcours peu en dessous de la bobine 6, avant de remonter jusqu'à l'organe d'entraînement 24 en prenant appui contre une portion cylindrique de la bobine 6. Lorsque la matière en bande est déroulée de la bobine, le diamètre de cette dernière diminuant, la longueur du parcours de la courroie situé entre le galet de renvoi inférieur 27 et l'organe d'entraînement 24 s'en trouve constamment variée. Le galet tendeur à pour but de compenser en tout temps ces variations. Pour ce faire, il est monté en coulissement le long d'une ouverture oblongue 28 et est relié à un mécanisme tendeur 30. Ce mécanisme peut être pourvu d'un moyen élastique, tel qu'un ressort de traction 31 par exemple, relié au galet tendeur 25 par un filin 32.The cheeks 21, 22 are held together by spacers 23 and allow in particular the arrangement of a drive member 24 for the rotation of the belt 16. From this drive member, the belt respectively runs around a tensioning roller 25, then around a plurality of return rollers 26 including a lower return roller 27 located at the lower end of the path slightly below the coil 6, before going up to the body d 24 when the strip material is unwound from the coil, the diameter of the latter decreasing, the length of the path of the belt between the lower return roller 27 and the drive member 24 is constantly varied. The purpose of the tensioning roller is to compensate for these variations at any time. To do this, it is slidably mounted along an oblong opening 28 and is connected to a tensioning mechanism 30. This mechanism can be provided with an elastic means, such as a tension spring 31 for example, connected to the tensioner roller 25 by a rope 32.

Comme mieux visible sur la figure 2, le dispositif d'entraînement 20, ajustable entre les parois 3, 4 de la structure portante 5, est maintenu en appui en l'une de ses extrémités sur une barre-support 29 et en l'autre extrémité par le biais de l'organe d'entraînement 24. La barre-support 29 est maintenue fixe entre les parois de la structure portante 5. L'organe d'entraînement 24 est préférentiellement constitué par une bague traversée d'un arbre d'avance 40. Cette arbre d'avance se trouve également maintenu entre les parois latérales 3, 4 du module 1 et se trouve relié en l'une de ses extrémités à un moteur électrique 41 par une courroie d'avance 42. C'est ce moteur électrique qui va pouvoir piloter le ou les dispositifs d'entraînement 20 adjacents associés au même arbre d'avance 40, par le biais des organes d'entraînement 24 correspondants.As better visible on the figure 2 , the drive device 20, adjustable between the walls 3, 4 of the supporting structure 5, is held in abutment at one of its ends on a support bar 29 and at the other end by means of the driving member 24. The support bar 29 is held stationary between the walls of the supporting structure 5. The drive member 24 is preferably constituted by a ring traversed by a feed shaft 40. This shaft of advance is also maintained between the side walls 3, 4 of the module 1 and is connected at one of its ends to an electric motor 41 by a feed belt 42. It is this engine electrical drive that will be able to drive the adjacent drive device or 20 associated with the same feed shaft 40, through the corresponding drive members 24.

Avantageusement, la structure portante 5 est montée sur des roulettes 8 permettant d'accroître la mobilité du module 1 et d'autoriser si nécessaire son déplacement dans un espace dégagé, libre de tout encombrement. Tel qu'illustré dans la figure 1, le module de la présente invention est doté d'une pluralité de bobines 6 réparties sur deux étages. Toutefois, on notera qu'une autre disposition de ces bobines, sur un seul ou sur plusieurs étages, pourrait être également adoptée. Comme illustré dans la figure 1, le nombre de dispositifs d'entraînement par bobine peu varier à volonté, suivant la largeur de la bande, sa longueur déroulée, son diamètre ou la cadence d'entraînement par exemple. Ainsi, les performances d'entraînement des bobines peuvent être notablement augmentées en utilisant plusieurs dispositifs d'entraînement pour piloter les bobines. Le couplage de plusieurs dispositifs sur une même bobine permet également de mieux maîtriser l'effet d'inertie que peut produire cette bobine lorsqu'elle est mise en rotation et de ce fait autorise aussi des vitesses d'avance pouvant être plus rapides.Advantageously, the supporting structure 5 is mounted on rollers 8 to increase the mobility of the module 1 and to authorize if necessary its displacement in a clear space, free of any bulk. As illustrated in figure 1 the module of the present invention is provided with a plurality of coils 6 distributed over two stages. However, it will be noted that another arrangement of these coils, on one or several stages, could also be adopted. As illustrated in figure 1 , the number of coil drive devices can vary at will, depending on the width of the strip, its unwound length, its diameter or the drive rate, for example. Thus, the drive performance of the coils can be significantly increased by using multiple drive devices to drive the coils. The coupling of several devices on the same coil also makes it possible to better control the effect of inertia that can produce this coil when it is rotated and thus also authorizes faster speeds of advance.

Pour améliorer les performances de l'entraînement des bobines, il est également possible, au moyen de courroies supplémentaires par exemple, de coupler plusieurs arbres d'avance 40 entre eux de façon à augmenter la puissance mécanique d'entraînement appliquée à certaines bobines. Cela peut être particulièrement utile lorsque les moteurs 41 sont dimensionnés pour délivrer une puissance moyenne alors qu'il serait nécessaire de pouvoir bénéficier d'une plus grande puissance dans le cas de l'entraînement d'une bobine de très grand diamètre par exemple.To improve the performance of the drive of the coils, it is also possible, by means of additional belts for example, to couple several advance shafts 40 between them so as to increase the mechanical power of drive applied to certain coils. This can be particularly useful when the motors 41 are dimensioned to deliver an average power while it would be necessary to be able to benefit from a greater power in the case of driving a very large diameter coil for example.

Selon le mode de réalisation décrit jusqu'ici, les bobines 6 qui sont disposées sur le même arbre d'avance 40 sont entraînées simultanément par le même moteur 41. Cependant, en guise de variante il serait parfaitement possible de rendre l'entraînement de chacune de ces bobines indépendant de façon à multiplier le nombre de vitesses et de cadences d'entraînement différentes que le module 1 pourrait restituer simultanément. A cet effet, il serait possible de perfectionner les arbres d'avance 40 de sorte qu'ils ne soient non pas constitués d'un seul tube mais d'une pluralité de tubes concentriques de diamètres différents montés en rotation indépendamment les uns des autres sur des paliers successifs solidaires de ces tubes. Ainsi il serait possible d'obtenir un arbre d'avance composé de différentes sections, chacune pouvant être entraînée d'une manière indépendante. Un autre mode de réalisation consisterait à doter certains ou tous les dispositifs d'entraînement 20 d'un moteur électrique 41 propre à chaque courroie 16. Ainsi, chaque organe d'entraînement 24 de chaque dispositif d'entraînement 20 pourrait être piloté par un moteur électrique 41 indépendant, qui soit par exemple directement embarqué sur le dispositif d'entraînement lui-même. Un tel agencement permettrait alors de piloter d'une manière différentiée le déroulement des bobines concernées afin de pouvoir bénéficier de vitesses et de cadences distinctes selon les besoins spécifiques de ces bobines.According to the embodiment described so far, the coils 6 which are arranged on the same feed shaft 40 are driven simultaneously by the same motor 41. However, as a variant it would be perfectly possible to make the drive of each of these independent coils so as to multiply the number of different speeds and training rates that the module 1 could restore simultaneously. For this purpose, it would be possible to improve the advance shafts 40 so that they are not made of a single tube but a plurality of concentric tubes of different diameters rotatably mounted independently of each other on successive bearings integral with these tubes. Thus it would be possible to obtain a feed shaft composed of different sections, each of which can be driven independently. Another embodiment would be to provide some or all of the drive devices 20 with an electric motor 41 specific to each belt 16. Thus, each drive member 24 of each drive device 20 could be driven by an engine independent electric 41, which is for example directly embedded on the drive device itself. Such an arrangement would then drive in a differentiated manner the unwinding of the coils concerned to be able to benefit from different speeds and rates according to the specific needs of these coils.

Grâce aux caractéristiques que présente l'objet de la présente invention, il devient possible d'accéder sans aucune difficulté à tous les arbres d'avance et à tous les porte-bobines. Ainsi, l'utilisation de moyens de manutention, tels que des transpalettes, des élévateurs ou des palans par exemple, peuvent être avantageusement mis à contribution pour le chargement/déchargement des bobines lourdes sans craindre que l'accès en soit limité, difficile, voire impossible. Le dégagement disponible autour du module de la présente invention offre ainsi des perspectives techniques et ergonomiques impensables auparavant avec un module confiné à l'intérieur de la machine travaillant la matière en bande.Thanks to the characteristics that presents the object of the present invention, it becomes possible to access without any difficulty to all the feed shafts and to all the reel carriers. Thus, the use of handling means, such as pallet trucks, elevators or hoists, for example, can be advantageously used for the loading / unloading of heavy coils without fear that access is limited, difficult or impossible. The clearance available around the module of the present invention thus offers perspectives technical and ergonomic unthinkable previously with a module confined inside the machine working the material band.

Avantageusement, le concept d'une unité externe à la machine permet de multiplier les possibilités que peut offrir un tel module par rapport à un dispositif de chargement de bobines installé au sein de la machine. A titre d'exemple, le diamètre des bobines de la matière en bande ou le nombre d'arbres porteurs de ces bobines n'est nullement limité par un volume fini, déterminé par l'espace disponible en machine entre les parois de son bâti. En option, il serait également possible de prévoir un agencement spécial pour les bobines lourdes, de très grand diamètre, à savoir de l'ordre de 400 mm. A cet effet, il serait souhaitable qu'un tel agencement puisse prendre place au bas du module, le plus près du sol de sorte que par exemple, la course de levage d'un transpalette soit suffisante pour mettre plus facilement en place la bobine en question.Advantageously, the concept of a unit external to the machine makes it possible to multiply the possibilities that such a module can offer with respect to a device for loading coils installed within the machine. For example, the diameter of the reels of the strip material or the number of bearing shafts of these reels is not limited by a finite volume, determined by the space available in the machine between the walls of its frame. Optionally, it would also be possible to provide a special arrangement for heavy coils, very large diameter, namely of the order of 400 mm. For this purpose, it would be desirable for such an arrangement to be able to take place at the bottom of the module, closest to the ground so that, for example, the lifting stroke of a pallet truck is sufficient to put the coil in place more easily. question.

Avantageusement, l'entraînement des bobines tel que prévu dans le module de la présente invention, ne nécessite aucune intervention de réglage en cours de production. Ceci n'est généralement pas le cas dans les systèmes actuels qui utilisent des freins mécaniques pour maîtriser l'inertie des bobines lors de chaque changement de vitesse.Advantageously, the drive of the coils as provided in the module of the present invention requires no adjustment during production. This is not usually the case in current systems that use mechanical brakes to control the inertia of the coils at each gear change.

Avantageusement encore, de part sa position hors machine, le module de la présente invention est entièrement accessible autant pour des travaux de préparation d'un travail à venir que pour des opérations de maintenance. Ainsi, il devient possible de travailler en temps masqué sur le module, sans nécessiter l'immobilisation de la machine lorsque celle-ci s'affaire à des travaux de découpage.Advantageously, from its off-machine position, the module of the present invention is fully accessible for both preparation work for a future work for maintenance operations. Thus, it becomes possible to work in masked time on the module, without requiring the immobilization of the machine when it is working on cutting work.

Grâce à la délocalisation hors de la machine de la fonction de déroulage ou de bobinage de la matière en bande, il devient avantageusement possible de conserver en machine une partie des dispositifs et organes utilisés lorsque la machine est prévue pour une configuration de découpage-éjection des déchets. Ainsi, la transformation de la machine d'une configuration prévue pour le découpage et l'éjection en une nouvelle configuration prévue pour l'estampage et inversement, s'en trouve d'autant plus facilitée et rapide à mettre en oeuvre. Aussi, on notera que la modification et l'adaptation de machines de découpage dépourvues de système d'estampage en est également rendue plus aisée.Thanks to the relocation of the unwinding or winding function of the web material out of the machine, it becomes advantageously possible to keep in a machine part of the devices and organs used when the machine is provided for a cutting-ejection configuration waste. Thus, the transformation of the machine from a planned configuration for cutting and ejection into a new configuration provided for stamping and vice versa, is all the more facilitated and quick to implement. Also, it will be noted that the modification and adaptation of cutting machines without stamping system is also made easier.

Parmi les multiples avantages qu'offre l'agencement hors machine d'un tel module, on mentionnera encore que d'une part, la place ainsi libérée en machine permet d'être exploitée à d'autres fins pour l'adaptation et l'agencement d'options diverses et que d'autre part, le dégagement qu'offre l'espace environnant du module peut également être exploité pour y adjoindre tout un éventail d'organes additionnels. Parmi ces organes, on citera en exemple des entraînements à courroie étroite pour des bobines de faible largeur, des axes supplémentaires de déroulement de bobines montées sur des arbres d'origine, ou encore, ainsi que représenté sur la figure 4, des cellules de lecture spécifiques 45, 46, 47, 48 pour la détection de motifs ou de raccords de bandes particulières comme les bandes à hologrammes ou celles dites à effet de diffraction. Pour ce qui est de ce dernier cas, on mentionnera que la lecture et le repérage des raccords et des motifs holographiques des bandes à effet de diffraction nécessite une course de réglage des cellules optiques 45 à 48 beaucoup plus importantes que dans le cas de la lecture des seules positions de motifs holographiques. A cet effet, et pour obtenir un dégagement suffisant autorisant le respect de distances optimales, les cellules de lecture 45 à 48 sont agencées de manière à pouvoir coulisser respectivement le long des barres verticales 49, 50, 51, 52. Les barres verticales 49 à 52 sont montées, de façon à pouvoir coulisser latéralement, sur deux traverses 53, 54 portées par des supports 55 et 56 fixés aux parois 3 et 4 de la structure portante 5. Actuellement, dans les modules confinés à l'intérieur de ces machines, il n'est souvent pas possible d'obtenir un dégagement suffisant permettant de respecter ces distances optimales. Or, grâce à l'objet de la présente invention, le module externe peut avantageusement servir de support à ce genre de dispositifs annexes sans que l'on soit restreint à un espace environnant limité.Among the many advantages offered by the off-machine arrangement of such a module, it will also be mentioned that on the one hand, the space thus released in a machine makes it possible to be exploited for other purposes for adaptation and arrangement of various options and that on the other hand, the clearance of the surrounding space of the module can also be exploited to add a range of additional bodies. Among these members, exemplary narrow belt drives for coils of small width, additional axes unwinding coils mounted on original trees, or, as shown in FIG. figure 4 , specific reading cells 45, 46, 47, 48 for the detection of patterns or special strip connections such as holograms or so-called diffraction bands. As regards the latter case, it will be mentioned that the reading and the marking of the connections and the holographic patterns of the diffraction-effect strips necessitates an adjustment run of the optical cells 45 to 48 which are much larger than in the case of reading. only positions of holographic patterns. For this purpose, and to obtain a sufficient clearance allowing the respect of optimal distances, the reading cells 45 to 48 are arranged so as to slide respectively along the vertical bars 49, 50, 51, 52. The vertical bars 49 to 52 are mounted, so that they can slide laterally on two crosspieces 53, 54 carried by supports 55 and 56 fixed to the walls 3 and 4 of the supporting structure 5. Currently, in the confined modules inside these machines, it is often not possible to obtain sufficient clearance to respect these optimum distances. However, thanks to the object of the present invention, the external module can advantageously serve as a support for this kind of ancillary devices without being restricted to a limited surrounding space.

Il convient de noter que le module tel que décrit est préférentiellement utilisé en tant que module dérouleur pour transférer une matière en bande depuis ce module vers une machine la travaillant. Or, on remarquera que le cheminement inverse pourrait si nécessaire être parfaitement obtenu avec le même module en inversant simplement sa fonction initiale de module dérouleur en un module enrouleur pour matière en bande usagée par exemple.It should be noted that the module as described is preferably used as an unwinder module for transferring a material strip from this module to a machine working. However, it will be noted that the reverse path could, if necessary, be perfectly obtained with the same module by simply reversing its initial unwinding module function in a retractor module for used web material for example.

On précisera enfin que par l'appellation matière en bande, on entend couvrir aussi bien l'utilisation d'une seule bande, de grande largeur par exemple, qu'une pluralité de bandes ou bandelettes placées les unes à côté des autres avec ou sans espaces interstitielles. Aussi, bien que la machine dans laquelle a été décrit le dispositif de la présente invention fait clairement référence à une presse à platine travaillant des éléments en plaque, on mentionnera que l'utilisation de ce dispositif n'est nullement limitée à de telles machines.Finally, it will be specified that by the term "web material" it is meant to cover both the use of a single band, of large width for example, and a plurality of strips or strips placed next to one another with or without interstitial spaces. Also, although the machine in which the device of the present invention has been described clearly refers to a platen press working plate elements, it will be mentioned that the use of this device is not limited to such machines.

De nombreuses améliorations peuvent être apportées au dispositif de la présente invention dans le cadre des revendications.Many improvements can be made to the device of the present invention within the scope of the claims.
