Abstract

The card printing machine includes a card feeder (10) supplying cards to a colour printing station (1) and a black and white printing station (2). These stations use thermal impression printing techniques, with a ribbon passing in front of the head. These are followed by a station which reverses the card (4). This includes a drum arranged to rotate the card through 180 degrees. After printing on both sides of the card in both colour and black and white, the card passes through a further station which applies the required electrical personalisation to it. The card then joins a stack (6). <IMAGE>

Bien entendu, les machines 1, 2 et 3 de la figure 1 peuvent présenter des différences importantes de l'une à l'autre, notamment en ce qui concerne le ruban et le système de pilotage, mais leur principe et leur mode de réalisation sont semblables.Of course, the machines 1, 2 and 3 of FIG. 1 can present significant differences from one to the other, in particular with regard to the ribbon and the control system, but their principle and their embodiment are alike.

Chaque dispositif de retournement 4 ou 7 comprend (figures 2, 3 et 4) un tambour horizontal 11 dans lequel la carte 9 est introduite à plat, guidée par une rainure de passage 12, dans le sens de la longueur; ce tambour pivote de ± 180° autour de son axe horizontal grâce à des roulements 50 qui sont portés par un châssis 51. La rotation du tambour 11 est obtenue par un moteur 23 dont l'arbre de sortie porte un pignon 52 qui vient se craboter sur une roue dentée 53 solidaire du tambour.Each turning device 4 or 7 comprises (FIGS. 2, 3 and 4) a horizontal drum 11 into which the card 9 is inserted flat, guided by a passage groove 12, lengthwise; this drum pivots ± 180 ° around its horizontal axis by means of bearings 50 which are carried by a frame 51. The rotation of the drum 11 is obtained by a motor 23 whose output shaft carries a pinion 52 which is clutched on a toothed wheel 53 secured to the drum.

Des rouleaux 13, 14, 15, 16 prennent en charge les déplacements de la carte 9 pour l'introduire dans le tambour puis, après retournement, pour l'acheminer à un autre poste de travail en aval ou en amont du tambour; ces rouleaux sont entraînés en rotation par des moyens moteur non représentés. D'autres rouleaux 17, 18 assurent les déplacements de la carte à l'intérieur du tambour.Rollers 13, 14, 15, 16 take charge of the movements of the card 9 to introduce it into the drum then, after turning over, to convey it to another work station downstream or upstream of the drum; these rollers are rotated by motor means not shown. Other rollers 17, 18 ensure the movements of the card inside the drum.

La distance entre, respectivement, d'une part, les rouleaux 13, 14 et 17, 18, et d'autre part les rouleaux 16, 17 et 17, 18 est inférieure à la longueur d'une carte en sorte qu'une carte entrant ou sortant dans le dispositif de retournement est successivement poussée et tirée par deux paires de rouleaux quel que soit le sens de son déplacement. Le rouleau d'entraînement 17 est doté d'un pignon 19, 20 à chaque extrémité faisant saillie à l'extérieur du tambour. Un moteur fixe 21, dont le pignon d'entraînement 22 est situé dans le même plan que les pignons d'extrémité, vient se craboter alternativement sur l'un ou l'autre pignon d'extrémité selon la position du tambour après rotation.The distance between, respectively, on the one hand, the rollers 13, 14 and 17, 18, and on the other hand the rollers 16, 17 and 17, 18 is less than the length of a card so that a card entering or leaving the turning device is successively pushed and pulled by two pairs of rollers whatever the direction of its movement. The drive roller 17 is provided with a pinion 19, 20 at each end projecting outside the drum. A fixed motor 21, the drive pinion 22 of which is situated in the same plane as the end pinions, comes to interlock alternately on one or the other end pinion according to the position of the drum after rotation.

Pendant le convoyage interne de la carte par les rouleaux 17, 18 et afin d'éviter le désaccouplement des pignons 19 ou 20 avec le pignon d'entraînement 22, le moteur de retournement 23 est alimenté pour créer un couple résistif au démarrage du moteur 21 et ce jusqu'à la fin du convoyage.During the internal conveying of the card by the rollers 17, 18 and in order to avoid the uncoupling of the pinions 19 or 20 with the drive pinion 22, the turning motor 23 is supplied to create a resistive torque when the motor starts 21 until the end of the conveying.

L'entrée ou la sortie de la carte 9 du tambour 11 est détectée par deux dispositifs optiques 40, 41, par exemple deux cellules photoélectriques, placés chacun à une extrémité du tambour et à l'extérieur de celui-ci.The entry or exit of the card 9 of the drum 11 is detected by two optical devices 40, 41, for example two photoelectric cells, each placed at one end of the drum and outside of it.

La rotation du tambour 11 est détectée par un dispositif optique comprenant une cellule photoélectrique 45 coopérant avec deux perçages 46 et 47 présents dans la flasque du tambour 11, diamétralement opposés.The rotation of the drum 11 is detected by an optical device comprising a photoelectric cell 45 cooperating with two holes 46 and 47 present in the flange of the drum 11, diametrically opposite.

Après détection d'une entrée de carte dans le tambour, dans le sens 43 ou le sens 44, écoulement d'un certain délai et absence de détection d'une sortie dans un sens ou dans l'autre, il est certain qu'une carte est présente dans le tambour et que la rotation va pouvoir être activée.After detection of a card entry in the drum, in direction 43 or direction 44, lapse of a certain delay and absence of detection of an exit in one direction or the other, it is certain that a card is present in the drum and the rotation will be able to be activated.

Avant de déclencher la commande de rotation du moteur 23, la position initiale du tambour est vérifiée en envoyant à travers le perçage 46 un faisceau lumineux qui est émis par un émetteur (non représenté) et détecté par la cellule photoélectrique 45. Après l'écoulement d'un délai inférieur au temps de rotation, il est vérifié que la cellule photoélectrique 45 est bien masquée par la rotation de la flasque du tambour; après l'écoulement d'un délai supérieur au temps de rotation, il est envoyé un faisceau lumineux, cette fois à travers le perçage 47 qui, détecté par la cellule 45, atteste de la rotation de 180° du tambour.Before triggering the rotation control of the motor 23, the initial position of the drum is checked by sending through the bore 46 a light beam which is emitted by a transmitter (not shown) and detected by the photoelectric cell 45. After the flow with a delay less than the rotation time, it is verified that the photoelectric cell 45 is well masked by the rotation of the flange of the drum; after the expiration of a delay greater than the rotation time, a light beam is sent, this times through the hole 47 which, detected by the cell 45, attests to the rotation of 180 ° of the drum.

Le moteur de retournement 23 entraîne la rotation du tambour 11 de ± 180° par rapport à une position initiale horizontale de la rainure d'introduction 24 des cartes réalisant le retournement de la carte autour de son grand axe.The reversing motor 23 drives the rotation of the drum 11 by ± 180 ° relative to an initial horizontal position of the card insertion groove 24 carrying out the reversal of the card around its major axis.

Le tambour est doté de moyens de reconnaissance, directement visibles 30, 31 par un opérateur, permettant de connaître le sens de la carte contenue dans le tambour, recto ou verso.The drum is provided with recognition means, directly visible 30, 31 by an operator, making it possible to know the direction of the card contained in the drum, front or back.

Un dispositif électronique de commande 55 du type microprocesseur, reçoit les signaux en provenance des dispositifs de détection 40, 41 et 45 et élaborent des signaux de commande des moteurs 21, 23 ainsi que des moyens moteurs d'entraînement (non représentés) des rouleaux 13 à 16.An electronic control device 55 of the microprocessor type, receives the signals from the detection devices 40, 41 and 45 and develops control signals for the motors 21, 23 as well as the drive motor means (not shown) of the rollers 13 to 16.

La carte 9 est introduite dans le tambour 11 par les rouleaux externes, référencés 13 et 14 d'un côté et 15, 16 de l'autre côté, selon son grand axe et en position à plat. Elle est prise en charge par les rouleaux internes 17, 18 qui prennent le relais des rouleaux externes de transit positionnés à moins d'une longueur de carte.The card 9 is introduced into the drum 11 by the external rollers, referenced 13 and 14 on one side and 15, 16 on the other side, along its major axis and in the flat position. It is supported by the internal rollers 17, 18 which take over from the external transit rollers positioned within one card length.

Lorsque la carte est entièrement à l'intérieur du tambour, rouleaux internes arrêtés et la position de la carte contrôlée, le moteur de retournement 23 est activé pour faire tourner le tambour de 180° dans un sens ou dans l'autre.When the card is entirely inside the drum, internal rollers stopped and the position of the card controlled, the turning motor 23 is activated to rotate the drum 180 ° in one direction or the other.

A la fin de la rotation, l'un des deux pignons 19, 20 situés aux extrémités de l'axe du rouleau moteur interne vient se craboter sur le pignon 22 du moteur 21 qui, commandé dans un sens ou dans l'autre, permet de diriger la carte en aval ou en amont du tambour 11.At the end of the rotation, one of the two pinions 19, 20 situated at the ends of the axis of the internal motor roller comes to clutch on the pinion 22 of the motor 21 which, controlled in one direction or the other, allows to direct the card downstream or upstream of the drum 11.

La carte retournée est prise en charge par les rouleaux externes 13 à 16 de transit positionnés à moins d'une longueur de carte des rouleaux internes 17, 18. La carte est ainsi acheminée vers un autre poste de travail, soit en amont, soit en aval du tambour.The returned card is taken care of by the external rollers 13 to 16 of transit positioned within a card length of the internal rollers 17, 18. The card is thus routed to another work station, either upstream or downstream of the drum.

La station 5 de personnalisation électrique est connue en elle-même. Elle est compatible avec tous les types de circuits intégrés ou puces électroniques existant sur le marché. Cette station 5 a pour but de personnaliser le circuit intégré qui a été placé dans une cavité de la carte, par exemple pour y enregistrer un code secret que seul l'utilisateur futur de la carte connaîtra.The station 5 for electrical personalization is known in itself. It is compatible with all types of integrated circuits or electronic chips existing on the market. The purpose of this station 5 is to personalize the integrated circuit which has been placed in a cavity of the card, for example to record a secret code there that only the future user of the card will know.
