Description

L'invention concerne un dispositif d'impression destiné à travailler sur un support étroit tel qu'un titre de transport ou analogue, et un appareil de traitement de titres comprenant un tel dispositif d'impression.The invention relates to a printing device intended to work on a narrow support such as a ticket or the like, and to a ticket processing apparatus comprising such a printing device.

Plus précisément, l'invention se rapporte à un dispositif d'impression traversé par le support d'impression étroit qui se déplace dans la direction de sa propre longueur, le dispositif comprenant une enclume ou contre-plaque constituée au moins en partie par un rouleau cylindrique de révolution pouvant tourner autour de son axe de façon que sa surface cylindrique accompagne pratiquement sans glissement le déplacement du support d'impression, et une tête d'impression à aiguilles mobile en translation transversalement au déplacement du support de façon à réaliser une impression sur celui-ci selon une génératrice du rouleau.More specifically, the invention relates to a printing device traversed by the narrow printing medium which moves in the direction of its own length, the device comprising an anvil or counter plate formed at least in part by a roller cylindrical of revolution able to rotate around its axis so that its cylindrical surface accompanies practically without sliding the movement of the print medium, and a print head with needles movable in translation transversely to the movement of the medium so as to perform a printing on this according to a generator of the roller.

On sait que le fonctionnement correct d'une tête d'impression à aiguilles exige que la distance entre la tête et la surface d'impression ait une valeur rigoureusement constante. Il faut donc que la tête soit guidée dans son mouvement de translation avec une grande précision de façon que sa distance à la génératrice du cylindre soit constante quelle que soit sa position.It is known that the correct operation of a needle print head requires that the distance between the head and the print surface has a strictly constant value. It is therefore necessary that the head is guided in its translational movement with great precision so that its distance from the generator of the cylinder is constant whatever its position.

Le but de l'invention est de fournir des moyens simples et efficaces pour assurer ce guidage.The object of the invention is to provide simple and effective means for this guidance.

Ce but est atteint selon l'invention en ce que le dispositif d'impression comprend un ensemble unitaire de guidage du rouleau en rotation et de guidage de la tête en translation.This object is achieved according to the invention in that the printing device comprises a unitary assembly for guiding the roller in rotation and for guiding the head in translation.

De préférence, l'ensemble unitaire de guidage comporte une surface de glissement cylindrique de révolution, coaxiale au rouleau, pour le guidage de la tête. Cette surface de glissement peut appartenir à un alésage d'un arbre fixe sur lequel est monté le rouleau, une barre solidaire de la tête d'impression pouvant coulisser dans cet alésage.Preferably, the unitary guide assembly comprises a cylindrical sliding surface of revolution, coaxial with the roller, for guiding the head. This sliding surface may belong to a bore of a fixed shaft on which the roller is mounted, a bar secured to the print head being able to slide in this bore.

Selon un mode de réalisation, la barre présente des dents de crémaillère qui coopèrent, pour l'entraînement de la tête en translation, avec au moins un pignon entraîné par un moteur.According to one embodiment, the bar has rack teeth which cooperate, for driving the head in translation, with at least one pinion driven by a motor.

Selon une autre caractéristique de l'invention, l'ensemble unitaire de guidage comprend des moyens indépendants de la surface de glissement de révolution pour assurer un positionnement angulaire constant de la tête autour de l'axe du rouleau. Ces moyens indépendants peuvent comprendre des galets rotatifs coopérant avec une tige solidaire de la tête d'impression et qui s'étend dans la direction de translation de celle-ci.According to another characteristic of the invention, the unitary guide assembly comprises means independent of the sliding sliding surface to ensure constant angular positioning of the head around the axis of the roller. These independent means may include rotary rollers cooperating with a rod integral with the print head and which extends in the direction of translation of the latter.

L'invention a également pour objet un appareil de traitement de titres,tels que des titres de transport ou analogues, comprenant un dispositif d'impression tel que défini ci- dessus pour l'impression sur les titres.The invention also relates to a ticket processing apparatus, such as tickets or the like, comprising a printing device as defined above for printing on tickets.

Un tel appareil peut comprendre au moins une courroie coopérant avec le titre sur une fraction de la largeur de celui-ci pour l'entraîner selon un trajet interne à l'appareil, et le rouleau peut présenter un décrochement pour loger la courroie en affleurement du reste de sa surface latérale.Such an apparatus may comprise at least one belt cooperating with the title over a fraction of the width of the latter to drive it along an internal path to the apparatus, and the roller may have a recess to accommodate the belt flush with the rest of its lateral surface.

D'autres caractéristiques de l'invention ressortiront de la description détaillée ci-après et des dessins annexés- dans lesquels :

  • - la figure 1 est une vue schématique en élévation d'un appareil de traitement de titres selon l'invention;
  • - la figure 2 est une vue partielle en perspective de l'appareil;
  • - la figure 3 est une coupe partielle selon la ligne III-III de la figure 1.
Other characteristics of the invention will emerge from the detailed description below and from the appended drawings in which:
  • - Figure 1 is a schematic elevational view of a ticket processing apparatus according to the invention;
  • - Figure 2 is a partial perspective view of the apparatus;
  • - Figure 3 is a partial section along line III-III of Figure 1.

L'appareil représenté schématiquement à la figure 1 est destiné au traitement de titres de transport constitués par des supports d'informations imprimés et magnétiques, à base de papier ou de carton. Un tel traitement peut comprendre une impression et/ou un enregistrement magnétique et/ou une lecture magnétique et peut avoir pour but par exemple la création d'un titre valable à partir d'un support vierge, le contrôle du titre ou son invalidation après utilisation.The apparatus shown diagrammatically in FIG. 1 is intended for the processing of tickets made up of printed and magnetic information carriers, based on paper or cardboard. Such processing may include printing and / or magnetic recording and / or magnetic reading and may, for example, be for the creation of a valid title from a blank medium, the control of the title or its invalidation after use. .

Le titre décrit dans l'appareil un trajet interne entre une entrée définie par deux galets 135 et 195 et une sortie définie par deux galets 163 et 203.The title describes in the device an internal path between an inlet defined by two rollers 135 and 195 and an outlet defined by two rollers 163 and 203.

Le titre est entraîné selon le trajet interne par deux courroies crantées 10, 10' se déplaçant parallèlement l'une à l'autre en étant espacées dans la direction de leur largeur, et sur chacune desquelles le titre s'appuie par une fraction de sa largeur, comme on peut le voir à la figure 3, où le titre est désigné par la lettre T.The ticket is driven along the internal path by two toothed belts 10, 10 'moving parallel to each other being spaced in the direction of their width, and on each of which the ticket is supported by a fraction of its width, as can be seen in Figure 3, where the title is designated by the letter T.

Les courroies 10 et 10', après être passées sur un galet 193 entraîné par un moteur M1 et sur un galet 194, passent entre les galets 135 et 195. Elles traversent ensuite un dispositif d'impression, qui sera décrit plus loin, en étant tendues entre deux galets 141 et 142. Les courroies sont ensuite déviées par un galet 161 et renvoyées par un galet 162 pour venir passer entre les galets 163 et 203. Un galet 192 les renvoie enfin vers le galet moteur 193.The belts 10 and 10 ', after having passed over a roller 193 driven by an M1 engine and over a roller 194, pass between the rollers 135 and 195. They then pass through a printing device, which will be described later, being stretched between two rollers 141 and 142. The belts are then deflected by a roller 161 and returned by a roller 162 to come pass between the rollers 163 and 203. A roller 192 finally returns them to the drive roller 193.

-La déviation par les galets 161 à 163 permet l'insertion, sur le trajet interne, d'une tête magnétique 170 et d'un détecteur de passage de titres 175 portés par une platine 171, 173. En regard de la platine sont prévues d'autres courroies 20,20' qui s'enroulent sur deux galets 201 et 203, ainsi que sur un galet de retour 202. Les courroies 20, 20' coopèrent avec la face supérieure du titre tandis que les courroies 10, 10' coopèrent avec sa face inférieure. Des moyens non représentés assurent la mise en tension des courroies.-The deflection by the rollers 161 to 163 allows the insertion, on the internal path, of a magnetic head 170 and a ticket passage detector 175 carried by a plate 171, 173. Next to the plate are provided other belts 20,20 'which are wound on two rollers 201 and 203, as well as on a return roller 202. The belts 20, 20' cooperate with the upper face of the ticket while the belts 10, 10 'cooperate with its underside. Means not shown ensure the tensioning of the belts.

Les galets et le moteur M1 sont montés sur un bâti 1 constitué par un flasque vertical.The rollers and the motor M1 are mounted on a frame 1 constituted by a vertical flange.

D'autres particularités de l'appareil pourront être trouvées dans la Demande de Brevet N° 83 11 444, déposée le 8 juillet 1983, ainsi que dans les demandes de brevets N° 84 10378 et N° 84 10379 , intitulées respectivement "Dispositif de traitement de titres cartonnés propre à la création et/ou au contrôle du titre" et "Dispositif pour l'impression de bandes-témoin de plan de vol pour la navigation aérienne", déposées le même jour que la présente Demande, au nom de la Demanderesse. Le contenu descriptif de ces Demandes de brevet est à considérer comme incorporé à la présente Demande de brevet.Other features of the device can be found in Patent Application No. 83 11 444, filed on July 8, 1983, as well as in Patent Applications No. 84 10378 and No. 84 10379, respectively entitled "Device processing of cardboard titles specific to the creation and / or control of the title "and" Device for printing flight plan witness strips for air navigation ", deposited on the same day as this Request, in the name of the Applicant. The descriptive content of these Patent Applications is to be considered as incorporated into this Patent Application.

L'enclume ou contre-plaque du dispositif d'impression est formée par les courroies 10 et 10' en coopération avec un rouleau 150 ayant la forme générale d'un cylindre de révolution. Selon l'invention (figure 3 ) , le rouleau 150 présente, de part et d'autre d'une partie lisse 151, des évidements cannelés 152 et 152' coopérant avec la face crantée des courroies 10 et 10' de façon que la face lisse de celles-ci affleure à la surface de la partie médiane 151 selon une génératrice du rouleau 150. Toutefois, il est clair que la présente invention peut aussi s'appliquer à d'autres modes de réalisation du trajet interne, qui ne s'appuieraient pas sur l'usage d'une ou plusieurs courroies.The anvil or counter plate of the printing device is formed by the belts 10 and 10 'in cooperation with a roller 150 having the general shape of a cylinder of revolution. According to the invention (Figure 3), the roller 150 pre feels, on either side of a smooth part 151, grooved recesses 152 and 152 'cooperating with the notched face of the belts 10 and 10' so that the smooth face of these is flush with the surface of the part median 151 along a generatrix of the roller 150. However, it is clear that the present invention can also be applied to other embodiments of the internal path, which would not be based on the use of one or more belts .

Une tête d'impression à aiguilles, dont le culot 145 et le canal d'aiguilles 146 sont représentés schématiquement à la figure 3, est montée de façon à réaliser une impression sur le titre T le long de la qénératrice du rouleau 150.Un dévidoir 143 de ruban encreur est solidaire de la tête d'impression.A needle print head, the base 145 and the channel of needles 146 are shown diagrammatically in FIG. 3, is mounted so as to produce an impression on the title T along the line of the roller 150. 143 of ink ribbon is secured to the print head.

Selon l'invention, un ensemble unitaire est prévu pour le guidage du rouleau 150 en rotation et le guidage de la tête d'impression en translation. Cet ensemble de guidage comprend un arbre creux, fixe, formé d'un fourreau 301 et d'une douille 302 emmanchée dans le fourreau, sur lequel le cylindre 150 est monté par l'intermédiaire de roulements à billes 303. Des joues en matière plastique 304, traversées par l'arbre 301, 302, sont vissées au rouleau 150 de part et d'autre de la longueur de celui-ci. Le fourreau 301 présente au voisinage de l'une de ses extrémités une collerette 305 par laquelle il est fixé grâce à des vis 306 sur la face arrière d'une embase 307 elle-même montée sur la face arrière du flasque 1 grâce à des vis 308 traversant des bossages 309 de l'embase. L'avant est le côté du flasque1, en avant de la figure 1 et vers la gauche de la figure 3, où se trouvent le rouleau 150 et les courroies 10 et 10', le côté opposé est appelé arrière.According to the invention, a unitary assembly is provided for guiding the roller 150 in rotation and guiding the print head in translation. This guide assembly comprises a hollow, fixed shaft, formed of a sleeve 301 and of a sleeve 302 fitted into the sleeve, on which the cylinder 150 is mounted by means of ball bearings 303. Plastic cheeks 304, crossed by the shaft 301, 302, are screwed to the roller 150 on either side of the length thereof. The sleeve 301 has, in the vicinity of one of its ends, a flange 305 by which it is fixed by means of screws 306 on the rear face of a base 307 itself mounted on the rear face of the flange 1 by means of screws 308 passing through bosses 309 of the base. The front is the side of the flange 1, in front of FIG. 1 and to the left of FIG. 3, where the roller 150 and the belts 10 and 10 'are located, the opposite side is called rear.

L'arbre 301, 302 traverse le flasque 1 et l'embase 307 et supporte en porte-à-faux le rouleau 150. L'arbre est alésé selon une surface cylindrique de révolution 310 coaxiale au rouleau 150, qui reçoit une barre 311 pouvant coulisser dans l'alésage. La barre 311 est solidaire d'une potence 312 qui supporte la tête d'impression 145, 146 (la partie supérieure de la potence et la tête sont arrachées à la figure 2), de sorte que le coulissement de la barre 311 dans l'alésage de l'arbre 301, 302 assure un guidage précis de la tête d'impression le long de la génératrice du rouleau 150, la distance entre la tête d'impression et l'enclume étant ainsi maintenue rigoureusement constante.The shaft 301, 302 crosses the flange 1 and the base 307 and supports the cantilever roll 150. The shaft is bored according to a cylindrical surface of revolution 310 coaxial with the roll 150, which receives a bar 311 which can slide into the bore. The bar 311 is integral with a bracket 312 which supports the print head 145, 146 (the upper part of the bracket and the head are cut away in FIG. 2), so that the sliding of the bar 311 in the bore of the shaft 301, 302 ensures precise guidance of the print head along the generatrix of the roller 150, the distance between the print head and the anvil being thus kept strictly constant.

Pour empêcher la rotation de la barre 311, et par conséquent de la tête d'impression, autour de l'axe commun 322 à L'alésage 310 et au rouleau 150, on a prévu des moyens de positionnement angulaire indépendants de la surface de glissement 310. Ces moyens de positionnement comprennent deux galets 313 montés de part et d'autre d'une tige 314 solidaire de la potence 312, et coopérant avec la tige. Celle-ci est située au-dessous de la barre 311 et les galets 313 tournent librement sur des axes verticaux montés sur un rebord horizon tal inférieur 315 de l'embase 307.To prevent rotation of the bar 311, and consequently of the print head, around the common axis 322 to the bore 310 and to the roller 150, angular positioning means are provided which are independent of the sliding surface. 310. These positioning means comprise two rollers 313 mounted on either side of a rod 314 secured to the bracket 312, and cooperating with the rod.
