Abstract

The invention concerns a machine comprising two feed rollers (3, 14), one of which at least is a power-operated roller, and a rotating printing drum (6) co-operating with a counter-printing power-operated roller (17). The rollers (17, 14) are borne by the ends of a lever consisting of two yokes, pivoting in its middle (11) and articulated thereat by an articulation with adjustable stop; The displacement of said feed roller (14) following the passage of an envelope (24") between the feed rollers (3, 14) causes the lever to pivot thereby bringing about a corresponding displacement of the counter-printing roller (17), if the latter has not already been displaced by at least said corresponding displacement during the passage of a preceding object (23").

Description

Machine d'impression d'objets plats, notamment d'enveloppes, à tambour d'impression et dispositif compensateur d'épaisseurPrinting machine for flat objects, in particular envelopes, with printing drum and thickness compensating device
La présente invention concerne les machines d'impression d'objets plats et, plus particulièrement, les machines de traitement de courrier destinées à apposer une marque d'oblitération ou d'affranchissement sur des enveloppes, par impression au moyen d'un tambour rotatif de marquage coopérant avec un contre- rouleau permettant d'obtenir l'effort de contre- impression.The present invention relates to machines for printing flat objects and, more particularly, mail processing machines intended to affix a cancellation or franking mark on envelopes, by printing by means of a rotary drum. marking cooperating with a counter-roller making it possible to obtain the counter-impression force.
Le document EP-A-0547922 , parmi bien d'autres, fait connaître une telle machine d'impression d'objets plats (en particulier d'enveloppes) d'épaisseurs diverses amenés successivement le long d'une table au moyen d'un mécanisme d'amenée et imprimés au moyen d'un mécanisme d'impression, le mécanisme d'amenée comprenant au moins deux galets, dont au moins un galet motorisé, entre lesquels passent les objets, le mécanisme d'impression comprenant un tambour tournant d'impression et un galet motorisé de contre-impression.Document EP-A-0547922, among many others, makes known such a machine for printing flat objects (in particular envelopes) of various thicknesses brought successively along a table by means of a feeding mechanism and printed by means of a printing mechanism, the feeding mechanism comprising at least two rollers, including at least one motorized roller, between which the objects pass, the printing mechanism comprising a rotating drum d and a motorized roller for counter-printing.
Les machines imprimant les marques d'oblitération ou d'affranchissement à l'aide d'un tambour rotatif utilisent aujourd'hui une motorisation pour entraîner les enveloppes et une autre pour piloter le tambour d'impression. Le mouvement du tambour est décrit précisément dans le document O-A-96/26502. Le moteur d'entraînement du tambour d'impression effectue un travail violent d'accélération pour permettre au tambour de rencontrer la lettre en synchronisme parfait. De plus, pour permettre le traitement des enveloppes épaisses, le moteur d'entraînement du tambour d'impression doit déplacer le rouleau de contre-impression. Comme ce dernier est plaqué fortement contre le tambour, le travail à effectuer brusquement par le moteur d'entraînement est très important . D'autre part, on emploie de plus en plus des moteurs pas-à-pas pour la motorisation du tambour d'impression. Si ceux-ci présentent de grands avantages, ils sont néanmoins relativement sensibles aux brusques variations de charge.The machines printing the cancellation or franking marks using a rotary drum today use a motorization to drive the envelopes and another to drive the printing drum. The movement of the drum is described precisely in document OA-96/26502. The print drum drive motor performs a violent acceleration work to allow the drum to meet the letter in perfect synchronism. In addition, to allow processing of thick envelopes, the print drum drive motor must move the counterprint roller. As the latter is pressed strongly against the drum, the work to be done suddenly by the drive motor is very important. On the other hand, more and more stepping motors are used for the motorization of the printing drum. While these have great advantages, they are nevertheless relatively sensitive to sudden load variations.
La présente invention a pour but de pallier ces divers inconvénients, et de diminuer sensiblement le travail à effectuer par le moteur d'entraînement du tambour d'impression. L'invention atteint son but dans le cadre d'une machine du type défini plus haut grâce à un dispositif automatique et simple de compensation d'épaisseur, à savoir que les axes du galet de contre-impression et de l'un des deux galets d'amenée sont portés par les extrémités d'un levier pivotant en son milieu et articulé à cet endroit par une articulation à butée, de telle sorte que le déplacement dudit galet d'amenée par suite du passage d'un objet entre les deux galets d'amenée entraîne un pivotement du levier et donc un déplacement correspondant du galet de contre- impression, si celui-ci n'a pas déjà été déplacé d'au moins ledit déplacement correspondant lors du passage d'un objet précédent.The present invention aims to overcome these various drawbacks, and to significantly reduce the work to be done by the drive motor of the printing drum. The invention achieves its object in the context of a machine of the type defined above thanks to an automatic and simple thickness compensation device, namely that the axes of the counter-impression roller and one of the two rollers feed are carried by the ends of a lever pivoting in the middle and articulated at this point by a hinge with a stop, so that the movement of said feed roller as a result of the passage of an object between the two rollers feed causes pivoting of the lever and therefore a corresponding displacement of the counter-impression roller, if the latter has not already been displaced by at least said corresponding displacement during the passage of a previous object.
Autrement dit, au lieu que le travail de déplacement du galet de contre-impression soit effectué par le moteur d'entraînement du tambour d'impression, il est en partie effectué par le moteur des galets d'amenée et l'enveloppe elle-même au moment où elle passe dans les galets d'amenée. Il y a donc une diminution de la puissance nécassaire du moteur du tambour et augmentation dans les mêmes proportions de la puissance du moteur entraînant les enveloppes. Les technologies des deux moteurs étant très différentes, économique pour l'entraînement de l'enveloppe et chère pour l'entraînement du tambour d'impression, la présente invention permet ainsi de diminuer sensiblement le coût de la machine. Avantageusement, ledit levier compensateur d'épaisseur est constitué par deux chapes articulées l'une sur l'autre par une articulation. Une vis traverse un prolongement de l'une des chapes pour s'appuyer sur l'autre, afin de constituer une butée réglable de ladite articulation.In other words, instead of the work of moving the counter-printing roller being carried out by the drive motor of the printing drum, it is partly carried out by the motor of the feed rollers and the casing itself. as it passes through the feed rollers. There is therefore a decrease in the necessary power of the drum motor and an increase in the same proportion of the power of the motor driving the casings. The technologies of the two motors being very different, economical for driving the envelope and expensive for driving the printing drum, the present invention thus makes it possible to significantly reduce the cost of the machine. Advantageously, said thickness compensating lever is constituted by two yokes articulated one on the other by an articulation. A screw passes through an extension of one of the yokes to rest on the other, in order to constitute an adjustable stop for said articulation.
De préférence, des ressorts rappellent respectivement les galets portés par le levier vers le contact avec le galet antagoniste et le tambour d'impression.Preferably, springs respectively recall the rollers carried by the lever towards the contact with the opposing roller and the printing drum.
Avantageusement, le galet de contre-impression est motorisé par le moteur du galet d'amenée au moyen d'un ensemble courroie-poulies.Advantageously, the counter-impression roller is motorized by the motor of the feed roller by means of a belt-pulley assembly.

La machine de traitement de courrier comporte une structure principale formée de deux platines verticales parallèles avant 1 et arrière l' reliées par des entretoises 2. Cette structure en caisson permet le montage et le guidage des divers éléments constitutifs de la machine.- Figure 6 is a similar view of the machine of Figure 1, showing a third step in the path of an envelope, after printing, - Figure 7 is a similar view of the machine of Figure 1, showing the arrival of a new envelope thinner than the envelope that has just been printed, - Figure 8 is a similar view of the machine of 1, showing the arrival of a new envelope thicker than the envelope which has just been printed. The mail processing machine has a main structure formed by two parallel vertical plates before 1 and rear 1 connected by spacers 2. This box structure allows the mounting and guiding of the various components of the machine.
Une table horizontale 22 est montée à l'avant, perpendiculairement à la platine 1, pour le guidage des enveloppes à imprimer.A horizontal table 22 is mounted at the front, perpendicular to the plate 1, for guiding the envelopes to be printed.
Le mécanisme d'amenée d'enveloppes comprend le galet moteur 3 monté à l'avant de la platine 1 sur l'arbre 4 qui est mis en rotation par le moteur 5, disposé à l'arrière de la platine l'.The mechanism for feeding envelopes comprises the drive roller 3 mounted at the front of the plate 1 on the shaft 4 which is rotated by the motor 5, disposed at the rear of the plate 1 '.
Le mécanisme d'impression comprend le tambour d'impression 6 qui est: gravé avec la marque à imprimer. Le tambour est monté, lui aussi à l'avant de la platine 1, sur l'arbre 7 mis en rotation par le moteur 8 disposé à l'arrière.The printing mechanism comprises the printing drum 6 which is: engraved with the mark to be printed. The drum is also mounted at the front of the plate 1 on the shaft 7 rotated by the motor 8 disposed at the rear.
Eventuellement, un mécanisme d'éjection d'enveloppe non représenté, constitué classiquement de galets, peut être disposé en aval du mécanisme d' impression .Optionally, a not shown envelope ejection mechanism, conventionally made up of rollers, can be arranged downstream of the printing mechanism.
La figure 3 montre la réalisation du levier articulé constituant le dispositif compensateur de l'invention. Il se compose de deux chapes en U 9 et 10, à angles coupés, montées tête-bêche et articulées l'une et l'autre sur un axe 11 vissé dans la platine 1 (cf. figure 1) et parallèle aux arbres 4 et 7. La chape supérieure 10 porte, sur un prolongement 25 de son dos disposé du côté de l'articulation 11, une vis 12 dont l'extrémité 26 est en contact avec l'intérieur du dos de la chape opposée inférieure 9. L'articulation 11 est donc une articulation à butée réglable permettant au levier constitué par les chapes 9, 10 de ne fonctionner que dans un sens de rotation.Figure 3 shows the embodiment of the articulated lever constituting the compensating device of the invention. It consists of two U-shaped yokes 9 and 10, with cut angles, mounted head to tail and hinged to each other on an axis 11 screwed into the plate 1 (see Figure 1) and parallel to the shafts 4 and 7. The upper yoke 10 carries, on an extension 25 of its back disposed on the side of the joint 11, a screw 12 whose end 26 is in contact with the inside of the back of the opposite opposite yoke 9. The articulation 11 is therefore an articulation with adjustable stop allowing the lever constituted by the yokes 9, 10 to operate only in one direction of rotation.
La chape 9 porte à son extrémité opposée à l'articulation 11 un axe tourillonnant 13 traversant la platine 1 par une lumière appropriée 27 et à l'extrémité avant duquel est monté un galet 14. Le galet 14 est libre et en pression de contact avec le galet moteur 3 par l'action d'un ressort de traction 15 reliant la chape 9 à une cheville 28 montée dans la platine 1 (cf. figure 1) .The yoke 9 carries at its end opposite the articulation 11 a journalling axis 13 passing through the plate 1 by an appropriate light 27 and at the front end of which is mounted a roller 14. The roller 14 is free and in contact pressure with the drive roller 3 by the action of a tension spring 15 connecting the yoke 9 to a pin 28 mounted in the plate 1 (see Figure 1).
La chape 10 porte à son extrémité opposée à l'articulation 11, à même distance que l'axe 13, un axe tourillonnant 16 sur lequel est monté le galet de contre-impression 17. Le galet de contre-impression 17 est en pression de contact avec le tambour d'impression 6 par l'action d'un ressort de traction 18 reliant la chape 10 à une cheville 29 montée dans la platine 1 (cf. figure 1)The yoke 10 carries at its end opposite the articulation 11, at the same distance as the axis 13, a swiveling axis 16 on which the counter-impression roller 17 is mounted. The counter-impression roller 17 is under pressure of contact with the printing drum 6 by the action of a tension spring 18 connecting the yoke 10 to a dowel 29 mounted in the plate 1 (cf. FIG. 1)
La rotation du galet de contre-impression 17 simultanée à celle du galet 3 est assurée par le moteur 5 au moyen de l'ensemble constitué des poulies 19,21 montées sur les arbres respectifs 4, 16 et de la courroie 20 (figure 1) .The rotation of the counter-printing roller 17 simultaneous with that of the roller 3 is ensured by the motor 5 by means of the assembly consisting of the pulleys 19, 21 mounted on the respective shafts 4, 16 and the belt 20 (FIG. 1) .
La figure 4 illustre la première étape de l'insertion d'une enveloppe. L'enveloppe 23 provenant d'un système classique de dépilage ne faisant pas partie de 1 ' invention est prise en charge par les galets d'amenée 3 et 14. La mise en rotation du galet 3 est assurée par le moteur 5 au moyen de l'arbre 4. L'épaisseur de l'enveloppe 23 contraint le galet 14 à se déplacer dans le sens de la flèche 30, c'est-à-dire à s'élever par rapport à sa position de repos. De ce fait, la chape 9 tourne dans le sens horaire autour de l'axe 11, et par l'intermédiaire du contact de la vis 12 avec la face intérieure de la chape 9, la chape 10 tourne également dans le sens horaire autour de 1 ' axe 11. Ainsi, le galet de contre-impression 17 s'éloigne du tambour d'impression 6, vers le bas, de la valeur de l'épaisseur de l'enveloppe 23, du fait que les axes de rotation des galets 14 et 17 sont disposés à des distances égales de l'axe 11.Figure 4 illustrates the first step in inserting an envelope. The casing 23 coming from a conventional unstacking system which is not part of the invention is supported by the feed rollers 3 and 14. The rotation of the roller 3 is ensured by the motor 5 by means of the shaft 4. The thickness of the envelope 23 forces the roller 14 to move in the direction of the arrow 30, that is to say to rise relative to its rest position. Therefore, the yoke 9 rotates clockwise around the axis 11, and through the contact of the screw 12 with the inner face of the yoke 9, the yoke 10 also rotates clockwise around 1 axis 11. Thus, the counter-printing roller 17 moves away from the printing drum 6, downwards, by the value of the thickness of the envelope 23, because the axes of rotation of the rollers 14 and 17 are arranged at equal distances from the axis 11.
La figure 5 montre l'étape suivante. Le tambour d'impression 6 est mis en rotation par le moteur 8 par l'intermédiaire de l'arbre 7. L'enveloppe 23 est maintenant engagée à la fois dans les galets d'amenée 3, 14 et entre le tambour d'impression 6 et le galet de contre-impression 17, et l'enveloppe 23 reçoit l'impression du tambour 6.Figure 5 shows the next step. The printing drum 6 is rotated by the motor 8 via the shaft 7. The casing 23 is now engaged both in the feed rollers 3, 14 and between the printing drum 6 and the counter-printing roller 17, and the envelope 23 receives the impression of the drum 6.
Ensuite, comme le montre la figure 6, l'enveloppe 23 quitte les galets d'amenée 3, 14 : l'action du ressort de rappel 15 ramène le galet 14 au contact du galet 3, alors que le galet de contre- impression 17 est toujours au contact de l'enveloppe, ce qui est rendu possible par l'articulation relative à butée des chapes 9 et 10. De ce fait, le mécanisme est prêt à recevoir une nouvelle enveloppe.Then, as shown in FIG. 6, the envelope 23 leaves the feed rollers 3, 14: the action of the return spring 15 brings the roller 14 into contact with the roller 3, while the counter-printing roller 17 is always in contact with the envelope, which is made possible by the articulation relative to the stop of the yokes 9 and 10. Therefore, the mechanism is ready to receive a new envelope.
La figure 7 montre l'arrivée d'une enveloppe 24' plus mince que l'enveloppe 23' qui l'a précédée et est en cours d'éjection. Naturellement, le galet 14 est libre de monter de l'épaisseur voulue, grâce à l'articulation 11 qui n'est pas bloquée du fait que le contre-tambour 17 avait déjà été déplacé vers le bas d'une distance correspondant à l'épaisseur de l'enveloppe 23', supérieure à celle dont doit monter le galet 14 pour laisser passer l'enveloppe 24'.Figure 7 shows the arrival of an envelope 24 'thinner than the envelope 23' which preceded it and is being ejected. Naturally, the roller 14 is free to mount the desired thickness, thanks to the articulation 11 which is not blocked because the counter-drum 17 had already been moved down a distance corresponding to the thickness of the envelope 23 ', greater than that which the roller 14 must mount to allow the envelope 24' to pass.
La figure 8 présente le cas contraire de l'arrivée d'une enveloppe 24" plus épaisse que l'enveloppe 23" qui l'a précédée. Le déplacement du galet 14 vers le haut, plus grand que dans le cas précédent, se fait et écarte par conséquent encore plus le galet 17 et le tambour 6 l'un de l'autre, sans incidence néfaste sur l'enveloppe précédente 23", du fait que l'impression de celle-ci est terminée. FIG. 8 shows the opposite case of the arrival of an envelope 24 "thicker than the envelope 23" which preceded it. The displacement of the roller 14 upwards, greater than in the previous case, is done and consequently separates the roller 17 and the drum 6 from each other even more, without detrimental impact on the preceding envelope 23 " , because the printing of this one is finished.
