Description

Dispositif d'impression d'un support en bande Device for printing a strip medium
La présente invention concerne un dispositif d'impression d'un support, par exemple un tronçon de bande pour former un ticket justificatif d'une transaction.The present invention relates to a device for printing a support, for example a strip section to form a ticket justifying a transaction.
Plus particulièrement, l'invention concerne des dispositifs d'impression dans lesquels la tête d'impression -par exemple à jet d'encre, à impacts ou thermique- est reliée pivotante à un chariot se déplaçant en va et vient, transversalement à la bande à imprimer, le long d'un guide rectiligne solidaire d'un bâti. La tête d'impression est maintenue en appui, par un ressort disposé entre le chariot et la tête, contre un pupitre lui faisant face et solidaire du bâti. Après l'exécution d'une ligne d'impression, la bande, par exemple un ruban de papier se présentant sous la forme d'un rouleau déroulé au fur et à mesure de l'impres- sion, est déplacée perpendiculairement au guide entre la tête et le pupitre par l'intermédiaire de galets montés pivotants sur le bâti. Lorsque le rouleau de bande contenu dans le dispositif est épuisé, il faut en installer un autre et amorcer le dispositif en insérant l'extrémité de la bande dans les galets et entre le pupitre et la tête. Dans un tel dispositif, cette mise en place s'avère délicate et toute mauvaise introduction génère des bourrages de la bande .More particularly, the invention relates to printing devices in which the printing head - for example inkjet, impact or thermal - is pivotally connected to a carriage moving back and forth, transversely to the strip to print, along a straight guide secured to a frame. The print head is held in abutment, by a spring arranged between the carriage and the head, against a console facing it and integral with the frame. After the execution of a printing line, the strip, for example a paper ribbon in the form of a roll unwound as the printing is carried out, is moved perpendicular to the guide between the head and console via rollers pivotally mounted on the frame. When the tape roll contained in the device is exhausted, another must be installed and the device must be primed by inserting the end of the tape into the rollers and between the desk and the head. In such a device, this installation proves to be delicate and any incorrect introduction generates jams of the strip.
Pour remédier à ces inconvénients, on connaît du document WO 96/05062 un dispositif d'impression comportant un bâti sur lequel un capot portant le pupitre et les galets est monté pivotant entre une position de fermeture dans laquelle la tête est en appui sur le pupitre et une position d'ouverture permettant la mise en place d'une bande vierge. Après avoir ouvert le capot on peut insérer un nouveau rouleau de bande, puis ce capot est refermé tandis que l'extrémité libre de la bande est maintenue manuellement de manière à être prise entre le pupitre et la tête une fois le capot dans sa position de fermeture. Dans un tel dispositif, la mise en place de la bande est facilitée, mais pendant le déplacement du capot entre ses deux positions, il se produit des chocs et des frottements entre la tête d'impression, contrainte dans une position inclinée par le ressort, et le pupitre. Ces chocs et frottements répétés peuvent conduire à la détérioration de la tête d'impression ou entraîner des jeux entre les différents éléments du dispositif, entraînant la dégradation de la qualité de l'impression. Selon l'invention, on propose un dispositif d'impression d'un support en bande comportant un bâti, un chariot mobile en translation le long d'un guide solidaire du bâti et portant une tête d' impression pivotante et un moyen élastique disposé entre le chariot et la tête d'impression, un capot portant un pupitre et relié pivotant au bâti entre une position fermée dans laquelle la tête d' impression est maintenue en appui sur le pupitre par le moyen élastique et une position ouverte, un organe de verrouillage porté par le bâti de manière escamotable entre une première position où il coopère avec une butée solidaire du capot et une seconde position dans laquelle il échappe à cette butée, caractérisé en ce que l'organe de verrouillage est solidaire d'un levier articulé au bâti, ce levier possédant une extrémité coopérant avec la tête d'impression de manière que dans le mouvement de l'organe de verrouillage entre sa première et sa seconde position, l'extrémité du levier provoque le pivotement de la tête d'impression à l' encontre de l'effet du moyen élastique.To overcome these drawbacks, document WO 96/05062 discloses a printing device comprising a frame on which a cover carrying the desk and the rollers is pivotally mounted between a closed position in which the head is supported on the desk. and an open position allowing the establishment of a blank strip. After opening the cover, a new roll of tape can be inserted, then this cover is closed while the free end of the strip is held manually so as to be taken between the desk and the head once the cover is in its position. closing. In such a device, the positioning of the strip is facilitated, but during the movement of the cover between its two positions, shocks and friction occur between the print head, constrained in a position inclined by the spring, and the music stand. These repeated shocks and rubs can lead to deterioration of the print head or cause play between the various elements of the device, leading to the degradation of the quality of the print. According to the invention, there is provided a device for printing a strip support comprising a frame, a carriage movable in translation along a guide secured to the frame and carrying a pivoting print head and an elastic means disposed between the carriage and the print head, a cover carrying a desk and pivotally connected to the frame between a closed position in which the print head is held in abutment on the desk by the elastic means and an open position, a locking member carried by the frame retractably between a first position where it cooperates with a stop secured to the cover and a second position in which it escapes this stop, characterized in that the locking member is secured to a lever articulated to the frame , this lever having one end cooperating with the print head so that in the movement of the locking member between its first and its second position, the extremi tee of the lever causes the print head to pivot against the effect of the elastic means.
Ainsi le pivotement de la tête d' impression provoqué par l'extrémité du levier dégage la tête du trajet du pupitre pendant le déplacement du capot entre ses deux positions. La tête n'est donc plus heurtée par le pupitre.Thus the pivoting of the print head caused by the end of the lever releases the head from the path of the desk during the movement of the cover between its two positions. The head is therefore no longer struck by the desk.
Avantageusement, l'extrémité du levier a une largeur correspondant à la longueur du déplacement du chariot. Ainsi, l'extrémité du levier peut coopérer avec la tête quelle que soit la position du chariot le long du guide .Advantageously, the end of the lever has a width corresponding to the length of the movement of the carriage. Thus, the end of the lever can cooperate with the head whatever the position of the carriage along the guide.
Selon un mode de réalisation particulier, l'or- gane de verrouillage comporte une surface de son actionne- ment entre ses deux positions, coopérant par appui avec la butée lors du pivotement du capot près de sa position de fermeture .According to a particular embodiment, the locking member has a surface for its actuation between its two positions, cooperating by pressing with the stop when the cover is pivoted near its closed position.
Ainsi, le pivotement de la tête est automatique- ment obtenu quand le capot est en fin de course de fermeture ou en début de course d'ouverture.Thus, the pivoting of the head is automatically obtained when the cover is at the end of the closing stroke or at the start of the opening stroke.
Le bouton poussoir peut être porté par le capot à l'aplomb de la surface d' ctionnement quand le capot est dans sa position de fermeture, la manoeuvre du bouton provoquant le déplacement de l'organe de verrouillage de sa première vers sa seconde position par glissement sur la surface d' actionnement .The push button can be carried by the cover plumb with the operating surface when the cover is in its closed position, the operation of the button causing the locking member to move from its first position to its second position by sliding on the actuating surface.
Le bouton poussoir, dans une variante de réalisation, peut être disposé sur le bâti, la manoeuvre du bouton provoquant le déplacement de l'organe de verrouillage de sa première vers sa seconde position par action sur une portion de manoeuvre de cet organe différente de la surface d' actionnement .The push button, in an alternative embodiment, can be arranged on the frame, the operation of the button causing the locking member to move from its first to its second position by action on an operating portion of this member different from the actuating surface.
Avantageusement, dans ces réalisations, un moyen de rappel élastique est disposé entre le bâti et l'organe de verrouillage pour rappeler l'organe de verrouillage dans sa première position.Advantageously, in these embodiments, an elastic return means is disposed between the frame and the locking member to return the locking member to its first position.
D'autres caractéristiques et avantages de l'invention ressortiront de la description qui suit d'un mode de réalisation.Other characteristics and advantages of the invention will emerge from the following description of an embodiment.
Il sera fait référence aux dessins annexés parmi lesquels :Reference will be made to the accompanying drawings, in which:
- la figure 1 est une vue simplifiée en perspective du dispositif selon l'invention ; - la figure 2 est une vue de côté simplifiée en coupe partielle du dispositif selon l'invention dans une position de fermeture du capot ;- Figure 1 is a simplified perspective view of the device according to the invention; - Figure 2 is a simplified side view in partial section of the device according to the invention in a closed position of the cover;
- la figure 3 est une vue de côté simplifiée en coupe partielle du dispositif selon l'invention dans une position intermédiaire entre les positions de fermeture et d'ouverture du capot ;- Figure 3 is a simplified side view in partial section of the device according to the invention in an intermediate position between the closed and open positions of the cover;
- la figure 4 illustre par une vue semblable à la figure 2 une variante de réalisation de l'invention dans laquelle le bouton poussoir est porté par le capot. Le bâti, représenté aux figures sous la forme d'un boîtier 1, porte une tige formant un guide 2, le long duquel coulisse un chariot 5 constituant de manière connue l'écrou d'un système vis/écrou dont la vis 6 est parallèle au guide 2 et accouplée à un moteur d'entraînement 3 solidaire du boîtier 1.- Figure 4 illustrates in a view similar to Figure 2 an alternative embodiment of the invention in which the push button is carried by the cover. The frame, shown in the figures in the form of a housing 1, carries a rod forming a guide 2, along which slides a carriage 5 constituting in known manner the nut of a screw / nut system whose screw 6 is parallel to the guide 2 and coupled to a drive motor 3 secured to the housing 1.
Le chariot 5 porte sur un flanc vertical parallèle à sa direction de coulissement une tête d'impression 7 pivotante autour d'un axe 8 parallèle au guide 2 et solidaire du chariot 5, et un ressort 9 disposé au-dessus de l'axe 8 entre le chariot 5 et la tête 7, dont l'effort tend à éloigner du flanc du chariot 5 l'extrémité supérieure de la tête 7.The carriage 5 carries on a vertical flank parallel to its direction of sliding a print head 7 pivoting about an axis 8 parallel to the guide 2 and integral with the carriage 5, and a spring 9 disposed above the axis 8 between the carriage 5 and the head 7, the force of which tends to move the upper end of the head 7 away from the side of the carriage 5.
Le boîtier 1 comporte une ouverture découvrant une partie 10 fermée par un capot 11 pivotant entre deux positions autour d'un axe 12 solidaire du boîtier 1 et disposé parallèlement au guide 2 le long du côté de la partie 10 opposé à ce guide 2. Un ressort en épingle 4 est disposé autour de l'axe 12 entre le boîtier 1 et le capot 11 de telle sorte que le ressort en épingle 4 tend à faire pivoter le capot 11 vers une position d'ouverture où il découvre l'ouverture du boîtier 1. Le capot 11 possède deux parois latérales (dont une seule est représentée aux figures 2 et 3) entre lesquelles s'étend un pupitre 13 offrant une surface plane en regard de la tête 7 et sur laquelle la tête 7 s'appuie elastiquement sous l'action du ressort 9 quand le capot 11 est dans une position de fermeture comme représenté à la figure 2. Le capot 11 porte par chacune de ses parois latérales deux butées 14 possédant une extrémité arrondie et disposées en regard l'une de l'autre. Un pignon, non représenté, monté pivotant sur le boîtier 1 de manière à ce que ses dents coopèrent avec celles d'une portion de roue dentée 11.1 du capot 11, est attelé à un amortisseur connu en lui-même tendant à freiner partiellement l'action du ressort en épingle 4 de telle sorte que l'ouverture du capot 11 soit à vitesse lente.The housing 1 has an opening revealing a part 10 closed by a cover 11 pivoting between two positions around an axis 12 integral with the housing 1 and disposed parallel to the guide 2 along the side of the part 10 opposite this guide 2. A hairpin spring 4 is arranged around the axis 12 between the housing 1 and the cover 11 so that the hairpin spring 4 tends to pivot the cover 11 to an open position where it discovers the opening of the housing 1. The cover 11 has two side walls (only one of which is shown in FIGS. 2 and 3) between which extends a desk 13 offering a flat surface facing the head 7 and on which the head 7 rests elastically under the action of spring 9 when the cover 11 is in a closed position as shown in FIG. 2. The cover 11 carries, by each of its side walls, two stops 14 having a rounded end and arranged opposite one another. A pinion, not shown, pivotally mounted on the housing 1 so that its teeth cooperate with those of a toothed wheel portion 11.1 of the cover 11, is coupled to a damper known in itself tending to partially brake the action of the hairpin spring 4 so that the opening of the cover 11 is at slow speed.
Un organe de verrouillage 17 est monté pivotant autour d'un axe 22 parallèle au guide 2 et solidaire par ses extrémités de chacun des deux côtés de la partie 10 perpendiculaires au guide 2. L'organe de verrouillage 17 comporte deux crochets 18 (dont un seul est représenté dans les figures 2 et 3) disposés de part et d'autre d'un levier 19 s 'étendant parallèlement au guide 2 et ayant une extrémité située au-dessous de l'extrémité inférieure de la tête 7. Les crochets 18 comportent chacun une proéminence supérieure 20 de profil convexe formant une surface d' actionnement de l'organe de verrouillage 17. Un ressort 21 est disposé entre le fond de la partie 10 du boîtier 1 et une portion de manoeuvre 23 de l'organe de verrouillage 17 s 'étendant en retrait de l'axe 22 du côté opposé au levier 19.A locking member 17 is mounted pivoting about an axis 22 parallel to the guide 2 and integral by its ends with each of the two sides of the part 10 perpendicular to the guide 2. The locking member 17 comprises two hooks 18 (one of which only is shown in Figures 2 and 3) arranged on either side of a lever 19 extending parallel to the guide 2 and having one end located below the lower end of the head 7. The hooks 18 each have an upper prominence 20 of convex profile forming an actuating surface of the locking member 17. A spring 21 is disposed between the bottom of the part 10 of the housing 1 and an operating portion 23 of the locking member 17 extending back from the axis 22 on the side opposite the lever 19.
On notera, au vu des figures, que l'organe de verrouillage 17 pivote entre deux positions extrêmes . Dans une première position, l'extrémité du levier 19 se trouve au-dessous de l'extrémité inférieure de la tête 7. Cette position est atteinte lorsque, le capot 11 étant dans sa position de fermeture, les crochets 18 retiennent chacun une butée 14 sous l'action du ressort 21, ou lorsque, le capot étant dans sa position d'ouverture, l'organe de verrouillage 17 est en appui sur l'élément mobile 16 d'un bouton poussoir 15 disposé sur le boîtier 1 à l'aplomb du ressort 21 (figure 1) . Dans une seconde position, correspondant à une position intermédiaire du capot 11 entre ses positions de fermeture et d'ouverture, l'extrémité arrondie des butées 14 solidaires du capot 11, étant en appui sur la proéminence 20 des crochets 18 en s ' opposant à l'effort du ressort 21, contrôle le pivotement du levier 19. L'extrémité du levier 19 a alors repoussé la tête 7 par action sur son extrémité inférieure à l' encontre de l'effet du ressort 9. Dans cette position, la tête 7 n'est plus en contact avec le pupitre 13.It will be noted, in view of the figures, that the locking member 17 pivots between two extreme positions. In a first position, the end of the lever 19 is located below the lower end of the head 7. This position is reached when, the cover 11 being in its closed position, the hooks 18 each retain a stop 14 under the action of the spring 21, or when, the cover being in its open position, the locking member 17 is supported on the movable element 16 of a push button 15 disposed on the housing 1 at the plumb of spring 21 (figure 1). In a second position, corresponding to an intermediate position of the cover 11 between its closed and open positions, the rounded end of the stops 14 integral with the cover 11, being in abutment on the protrusion 20 of the hooks 18 while opposing the force of the spring 21, controls the pivoting of the lever 19. The end of the lever 19 then pushed back the head 7 by action on its lower end against the effect of the spring 9. In this position, the head 7 is no longer in contact with the console 13.
En fonctionnement, le capot 11 étant dans sa position de fermeture et l'organe de verrouillage 17 dans sa première position, les crochets 18 retiennent chacun une butée 14 empêchant l'ouverture du capot 11 malgré l'effort exercé par le ressort en épingle 4. L' actionnement du bouton 15 provoque le coulissement de sa partie mobile 16 dont une extrémité vient appuyer sur la portion de manoeuvre 23 de l'organe de verrouillage 17 en s 'opposant à l'effort exercé par le ressort 21 sur cette portion de manoeuvre 23. L'organe de verrouillage 17 bascule alors vers sa seconde position. Les crochets 18 de l'organe de verrouillage 17 laissent alors échapper les butées 14 qui viennent en appui des proéminences 20 et maintiennent l'organe de verrouillage 17 dans sa seconde position même si le contact entre le bouton 15 et la portion de manoeuvre 23 de l'organe de verrouillage 17 a cessé. Dans sa seconde position l'organe de verrouillage 17 appuie, par l'intermédiaire du levier 19, sur l'extrémité inférieure de la tête 7 provoquant son pivotement en s 'opposant à l'effort du ressort 9. La tête 7 n'est alors plus au contact du pupitre 13. Sous l'action du ressort en épingle 4 en appui sur le capot 11, l'ouverture du capot se poursuit tandis que du fait du profil des proéminences 20, l'organe de verrouillage 17 revient progressivement dans sa première position sous l'effet des ressorts 21. L'ouverture du capot 11 une fois achevée, un opérateur insère un nouveau rouleau de bande.In operation, the cover 11 being in its closed position and the locking member 17 in its first position, the hooks 18 each retain a stop 14 preventing the opening of the cover 11 despite the force exerted by the pin spring 4 The actuation of the button 15 causes its movable part 16 to slide, one end of which presses on the operating portion 23 of the locking member 17 while opposing the force exerted by the spring 21 on this portion of operation 23. The locking member 17 then switches to its second position. The hooks 18 of the locking member 17 then let escape the stops 14 which bear against the projections 20 and keep the locking member 17 in its second position even if the contact between the button 15 and the operating portion 23 of the locking member 17 has ceased. In its second position, the locking member 17 presses, via the lever 19, on the lower end of the head 7 causing it to pivot by opposing the force of the spring 9. The head 7 is not then no longer in contact with the desk 13. Under the action of the hairpin spring 4 bearing on the cover 11, the opening of the cover continues while, due to the profile of the protrusions 20, the locking member 17 gradually returns in its first position under the effect of the springs 21. When the cover 11 is opened, an operator inserts a new roll of tape.
Le capot 11 étant dans sa position d'ouverture et l'organe de verrouillage 17 dans sa première position mais au contact de l'élément mobile 16 du bouton 15, le capot 11 est progressivement refermé sous l'action de l'opérateur s 'opposant à l'effort du ressort en épingle 4. Les butées 14 viennent au contact des proéminences 20 entraînant le pivotement progressif de l'organe de ver- rouillage 17 vers sa seconde position, s 'opposant ainsi à l'action du ressort 21. L'organe de verrouillage 17, par l'intermédiaire du levier 19, dégage alors la tête 7 du trajet suivi par le pupitre 13 solidaire du capot 11. A la fin du pivotement du capot 11, les butées 14 quittant les proéminences 20 sont capturées par les crochets 18 de l'organe de verrouillage 17 revenant de sa seconde position dans sa première position sous l'action exercée par le ressort 21 sur la portion de manoeuvre 23. Le rappel de l'organe de verrouillage dans sa première position provoque l'abaissement du levier 19 dont l'extrémité ne s'oppose alors plus à l'action du ressort 9 qui applique à nouveau la tête 7 sur le pupitre 13.The cover 11 being in its open position and the locking member 17 in its first position but in contact with the movable element 16 of the button 15, the cover 11 is gradually closed under the action of the operator s' opposing the force of the hairpin spring 4. The stops 14 come into contact with the protuberances 20 causing the progressive pivoting of the locking member 17 towards its second position, thus opposing the action of the spring 21. The locking member 17, by means of the lever 19, then releases the head 7 from the path followed by the console 13 secured to the cover 11. At the end of the pivoting of the cover 11, the stops 14 leaving the prominences 20 are captured by the hooks 18 of the locking member 17 returning from its second position to its first position under the action exerted by the spring 21 on the operating portion 23. The return of the locking member to its first position causes lowering of levi er 19, the end of which no longer opposes the action of the spring 9 which again applies the head 7 to the console 13.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et on peut y apporter des variantes de réalisation sans sortir du cadre de l'invention.Of course, the invention is not limited to the embodiment described and it is possible to make variant embodiments without departing from the scope of the invention.
En particulier, bien que le bouton poussoir ait été représenté agissant directement sur l'organe de verrouillage, on peut disposer le bouton poussoir pour qu'il agisse, par une extrémité biseautée de sa partie mobile, sur la proéminence 20 d'un des crochets 18. Cette variante est représentée à la figure 4. Le bouton poussoir 15a est fixé sur le capot 11, au-dessus de la proéminence 20 d'un des crochets 18. La partie mobile 16a de ce bouton poussoir possède une extrémité biseautée 16b. La partie obile 16a est maintenue en partie haute du bouton poussoir par un ressort 15b de raideur inférieure au ressort en épingle 4. Ainsi, lorsque la partie mobile 16a est enfoncée par l'opérateur, l'extrémité biseautée 16b vient en appui de la proéminence 20 et provoque le basculement de l'organe de verrouillage 17 entraînant la libération des butées 14. Le capot 11 pivote alors légèrement vers sa position ouverte sous l'action du ressort en épingle 4 en provoquant la compression du ressort 15b entre le corps du bouton poussoir solidaire du capot et la partie mobile 16a maintenue enfoncée par l'opérateur. Les butées 14 sont alors en appui des proéminences 20 et l'opérateur peut cesser sa pression sur la partie mobile 16a pour laisser le capot 11 achever son pivotement . Par ailleurs, bien que l'organe de verrouillage ait été représenté comportant des crochets équipés d'une proéminence, une autre variante pourrait consister à réaliser des crochets dénués de proéminence. L'opérateur doit alors actionner le bouton poussoir 15 durant la totalité des phases d'ouverture et de fermeture, de manière à assurer, outre la libération des butées, le maintien de la tête en position dégagée. In particular, although the push button has been shown acting directly on the locking member, the push button can be arranged so that it acts, by a beveled end of its movable part, on the prominence 20 of one of the hooks 18. This variant is shown in FIG. 4. The push button 15a is fixed on the cover 11, above the prominence 20 of one of the hooks 18. The movable part 16a of this push button has a beveled end 16b. The part obile 16a is held in the upper part of the push button by a spring 15b of lower stiffness than the pin spring 4. Thus, when the movable part 16a is pressed by the operator, the beveled end 16b comes to bear on the prominence 20 and causes the locking member 17 to tilt, causing the stops 14 to be released. The cover 11 then pivots slightly towards its open position under the action of the hairpin spring 4 causing the compression of the spring 15b between the body of the integral push button of the cover and the movable part 16a held down by the operator. The stops 14 are then in support of the prominences 20 and the operator can stop pressing on the movable part 16a to let the cover 11 complete its pivoting. Furthermore, although the locking member has been shown comprising hooks equipped with a prominence, another variant could consist in making hooks devoid of prominence. The operator must then actuate the push button 15 during all of the opening and closing phases, so as to ensure, in addition to the release of the stops, the maintenance of the head in the released position.
