- the embodiment illustrated in Figures 1 to 5 includes a carriage 1 carrying a print head 2 of a first type plugged into this carriage and which can be exchanged by at least one print head 3 from another type.
- the carriage 1 is slidably mounted on a shaft 5 fixed on the printer frame 7 thanks to a piece of attachment 8 and moves back and forth through a document to print it.
- the printer has a maintenance station 6 arranged laterally outside the printing area and which is intended to prevent ink drying in the print head nozzles and clogging of these nozzles.
- the maintenance station 6 includes two caps for this purpose. 10 and 11 arranged side by side on a cap holder 12 itself mounted on a movable support 14 of complex structure.
- the two caps 10 and 11 are arranged side by side in a direction perpendicular to the direction 15 (fig. 2a) of movement of the carriage 1 and the movable support 14 is arranged so as to perform a first translational movement relative to the frame 7 to have one or the other of the caps 10.11 opposite of the print head 2 or 3 plugged into the carriage.
- This movable support 14 comprises a support plate 16 which carries the cap holder 12 and which is connected to a intermediate plate 18 by a pair of flat springs 17 substantially parallel to direction 15.
- the plate intermediate 18 is connected by a second pair of springs plates 19 perpendicular to the first pair at a plate 20 secured to the frame 7 of the printer.
- the maintenance station is provided with a selection mechanism and control 25, comprising a feeler lever 26 pivotally mounted at 27 on the carriage 1.
- This lever 26 has a feeler element 28 cooperating with the print head 2 or 3 plugged in.
- feeler lever 26 occupies an angular position different depending on the plug-in print head. So the print head 3 of FIG. 4a has a width larger than the print head 2 of FIG. 2a and the lever is therefore pivoted by an angle of about 25 ° on the cart.
- the mechanism 25 further comprises a fixed ramp 30 on the support plate 16 and capable of cooperating with a finger 29 provided at the end of the feeler lever 26.
- a finger 29 provided at the end of the feeler lever 26.
- this finger 29 comes into contact with the ramp 30 to move the support plate 16 to the left at the Figure 3b.
- finger 29 passes beside the ramp 30 when the wider print head 3 is plugged in on the carriage 1 ( Figures 4a to 4c).
- the mechanism 25 also has a pusher 33 in tooth 34 attached to the carriage 1 and which is intended to cooperate with a boss 35 in the form of an integral cam of the support plate 16.
- This boss 35 has two sliding sides 36 and 37 separated by a point on which the tooth 34 is supported when the carriage 1 is moved to maintenance station 6. So tooth 34 is facing the flank 37, when the finger 29 passes to side of the ramp 30 (fig. 4b), and cooperates with this sidewall 37 to push the support plate 16 to the right at the Figure 4c, to arrange the cap 10 opposite the print head 3.
- tooth 34 comes into contact with the sidewall 36 and moves the support plate 16 towards the left in Figure 3c to place the cap 11 opposite of the print head 2.
- the complex support 14 makes it possible to accomplish the moving the caps for selection and their application against the print head by a construction very simple and requiring no training particular, if not the movement of the carriage.
- feeler lever 26 is brought to a predetermined angular position to cooperate or not with the ramp 30 on the support plate 16 so as to obtain the selection of the cap which is placed opposite the print head.
- the lateral translation of the support plate is then performed by sliding tooth 34 along a of the two sides of the boss 35. After this lateral translation, the carriage still causes the cap to be applied selected against the print head and then be immobilized in the maintenance station with the nozzles covered by the appropriate cap.
- printing the support plate 16 returns under the elastic effect flat springs 17 and 19 in their initial position illustrated in Figures 2a, 3a, 4a and 5a.
- feeler lever 26 could be replaced by a projecting part of the printhead acting directly on the ramp 30.
- the movement of the support plate caps could also be done by action direct on cam-shaped boss 35 without preselection by the ramp and with or without the presence of a feeler lever 26.
- the two pairs of flat springs 17 and 19 could be replaced by any other mechanism allowing lateral and application movements of the caps, for example by means of levers requested by springs to a rest position.
- the support plate 16 would carry a cap central and two side caps for example.
- the direction and magnitude of the perpendicular translational movement will then be defined by the type of print head cares.
- One or more caps could be connected by flexible tube to a suction pump allowing priming the print head or fitted with a ink absorbing pad.
- the maintenance station may also be equipped with one or more mud flaps intended wipe the front of the print heads. These flaps could be retractable or not on the mobile support or on the frame.

Dans les imprimantes à jet d'encre, il est conventionnel de protéger les buses d'éjection d'encre de la tête d'impression, lorsqu'elle se trouve en position de repos durant un temps prolongé entre des périodes d'impression, ceci afin d'éviter un séchage de l'encre conduisant à un bouchage des buses.In inkjet printers, it is to protect the ink ejection nozzles from the print head, when it is in the position rest for an extended time between periods in order to avoid drying of the ink leading to blockage of the nozzles.
A cet effet, on applique contre la plaque des buses un capuchon qui maintient un certain taux d'humidité.To this end, a nozzle is applied against the nozzle plate. hood that maintains a certain humidity level.
Le dispositif faisant l'objet de la présente invention s'applique à une imprimante munie d'une tête d'impression interchangeable enfichable dans le chariot mobile d'impression.The device which is the subject of the present invention applies to a printer with a printhead interchangeable plug-in in the mobile carriage printing.
Différents types de têtes peuvent être enfichés dans le chariot, par exemple une tête à encre noire ou une tête à encre multicolore.Different types of heads can be plugged into the carriage, for example a black ink head or a head with multicolored ink.
Pour éviter un salissement, via le capuchon, d'une tête par l'encre d'une autre tête, par exemple d'une tête couleur par une tête noire, on prévoit des capuchons respectifs pour chaque type de tête enfichée. To avoid soiling, via the cap, of a head by the ink of another head, for example of a head color with a black head, caps are provided respective for each type of plug-in head.
Le brevet US 5,155,497 décrit une station de maintenance pour une imprimante de ce type. Cette station comprend un support tournant à 180° autour d'un axe parallèle à la direction de déplacement du chariot et sur lequel sont montés en positions opposées deux capuchons par l'intermédiaire de deux coulisseaux déplaçables longitudinalement le long de cette direction de déplacement du chariot mobile. Après détection du type de tête d'impression monté sur le chariot, le support tournant met en place par rotation le coulisseau et le capuchon correspondant à la tête, le chariot entraíne ensuite le coulisseau longitudinalement pour appliquer le capuchon contre la plaque des buses.US Patent 5,155,497 describes a station maintenance for a printer of this type. This station includes a support rotating 180 ° around an axis parallel to the direction of travel of the carriage and on which are mounted in opposite positions two caps via two movable slides longitudinally along this direction of moving the moving carriage. After detection of the type of print head mounted on the carriage, the support turning rotates the slide and the cap corresponding to the head, the carriage drives then the slide longitudinally to apply the cap against the nozzle plate.
Cette station de maintenance comprend un grand nombre de pièces et est d'une construction compliquée.This maintenance station includes a large number of parts and is of complicated construction.
Le but de la présente invention est de remédier à ces inconvénients et elle est caractérisée à cet effet par le fait que la station de maintenance comprend un support de capuchons sur lequel les capuchons sont disposés côte à côte suivant une direction perpendiculaire à la direction de déplacement du chariot, ce support étant agencé de façon à effectuer sous l'action du mécanisme de sélection et de commande, d'une part, un premier mouvement de translation par rapport au bâti suivant une direction parallèle à ladite direction perpendiculaire pour mettre l'un des capuchons en regard de la tête d'impression enfichée sur le chariot et, d'autre part, un second mouvement de translation par rapport au bâti suivant une seconde direction perpendiculaire à ladite direction perpendiculaire faisant un angle tel avec la direction de déplacement du chariot que le capuchon sélectionné en regard de la tête enfichée sur le chariot soit appliqué contre cette tête enfichée lors dudit second mouvement de translation.The object of the present invention is to remedy these disadvantages and it is characterized for this purpose by the the maintenance station includes a support for caps on which the caps are arranged side by side coast in a direction perpendicular to the direction movement of the carriage, this support being arranged way to perform under the action of the selection mechanism and control, on the one hand, a first movement of translation relative to the frame in a direction parallel to said perpendicular direction to put one of the caps next to the print head plugged into the carriage and, secondly, a second translational movement relative to the frame according to a second direction perpendicular to said direction perpendicular making such an angle with the direction of movement of the carriage as the selected cap in look of the head plugged into the carriage is applied against this head inserted during said second movement of translation.
Par ces mesures, on obtient une construction très simple, peu encombrante comportant un nombre de pièces réduit et qui est d'un prix de revient modéré.By these measures, we obtain a very simple, space-saving with a number of parts reduced and which is of a moderate cost price.
Selon un mode d'exécution favorable, le mécanisme de sélection et de commande comprend un levier de sélection monté sur le chariot et coopérant avec la tête d'impression enfichée sur le chariot pour occuper des positions distinctes selon le type de tête d'impression enfichée, ce levier de sélection étant agencé de façon à coopérer avec une pièce solidaire du support de façon que ce dernier soit déplacé suivant le premier mouvement de translation pour opérer la sélection du capuchon à appliquer.According to a favorable mode of execution, the mechanism of selection and control includes a selection lever mounted on the carriage and cooperating with the head plugged into the carriage to occupy separate positions depending on the type of printhead inserted, this selection lever being arranged so as to cooperate with a part secured to the support so that the latter is moved following the first movement of translation to operate the cap selection at apply.
Grâce à ces caractéristiques, la commande de sélection du capuchon à appliquer est effectuée de façon fiable et simple.Thanks to these features, the selection command of the cap to be applied is performed reliably and simple.
Selon un mode d'exécution préféré, le support est relié au bâti par l'intermédiaire de deux paires de ressorts plats perpendiculaires entre eux et mis en série, une première des deux paires de ressorts plats autorisant le premier mouvement de translation et la seconde paire contrôlant le second mouvement de translation.According to a preferred embodiment, the support is connected to the frame via two pairs of flat springs perpendicular to each other and placed in series, a first of the two pairs of flat springs allowing the first translational movement and the second pair controlling the second translational movement.
Cette disposition assure un fonctionnement fiable tout en ayant un nombre de composants très réduit.This arrangement ensures reliable operation while by having a very small number of components.
D'autres avantages ressortent des caractéristiques exprimées dans les revendications dépendantes et de la description exposant ci-après l'invention plus en détail à l'aide de dessins qui représentent schématiquement et à titre d'exemple un mode d'exécution. Other advantages emerge from the characteristics expressed in the dependent claims and the description setting out the invention below in more detail at using drawings which represent schematically and at as an example an execution mode.
La figure 1 est une vue schématique en perspective d'une partie de l'imprimante montrant en particulier la station de maintenance.Figure 1 is a schematic perspective view of a part of the printer showing in particular the maintenance station.
Les figures 2a et 2b sont des vues frontales montrant le chariot a) en dehors de la station de maintenance et b) parqué dans la station de maintenance.Figures 2a and 2b are front views showing the truck a) outside the maintenance station and b) parked in the maintenance station.
Les figures 3a, 3b et 3c sont des vues en plan du chariot avec une première tête d'impression, a) en dehors de la station de maintenance, b) en entrant dans la station de maintenance pendant la sélection du capuchon, et c) à l'arrêt dans la station de maintenance.Figures 3a, 3b and 3c are plan views of the carriage with a first printhead, a) outside of the maintenance station, b) when entering the station maintenance during cap selection, and c) to shutdown in the maintenance station.
Les figures 4a, 4b et 4c sont également des vues en plan du chariot avec une seconde tête d'impression dans trois positions différentes par rapport à la station de maintenance.Figures 4a, 4b and 4c are also views in plan of the carriage with a second print head in three different positions in relation to the maintenance.
Les figures 5a, 5b et 5c sont des vues latérales montrant le chariot dans des positions différentes par rapport à la station de maintenance, en 5a le chariot est en dehors de cette dernière, en 5b le chariot est à l'intérieur de la station et muni de la première tête d'impression, et en 5c il est à l'intérieur de la station mais muni de la seconde tête d'impression.Figures 5a, 5b and 5c are side views showing the carriage in different positions relative to at the maintenance station, in 5a the trolley is in outside of the latter, in 5b the carriage is inside of the station and fitted with the first print head, and in 5c it is inside the station but with the second print head.
Le mode d'exécution illustré aux figures 1 à 5 comprend
un chariot 1 portant une tête d'impression 2 d'un
premier type enfichée sur ce chariot et qui peut être
échangée par au moins une tête d'impression 3 d'un autre
type. Le chariot 1 est monté coulissant sur un arbre 5
fixé sur le bâti 7 de l'imprimante grâce à une pièce de
fixation 8 et se déplace par un mouvement de va-et-vient
au travers d'un document pour l'imprimer.The embodiment illustrated in Figures 1 to 5 includes
a
L'imprimante présente une station de maintenance 6
aménagée latéralement hors de la zone d'impression et qui
est destinée à prévenir un séchage de l'encre dans les
buses des têtes d'impression et un bouchage de ces buses.
La station de maintenance 6 comprend à cet effet deux capuchons
10 et 11 disposés côte à côte sur un porte-capuchon
12 lui-même monté sur un support mobile 14 de
structure complexe. Les deux capuchons 10 et 11 sont disposés
côte à côte suivant une direction perpendiculaire à
la direction 15 (fig. 2a) de déplacement du chariot 1 et
le support mobile 14 est agencé de façon à effectuer un
premier mouvement de translation par rapport au bâti 7
pour disposer l'un ou l'autre des capuchons 10,11 en regard
de la tête d'impression 2 ou 3 enfichée sur le chariot.The printer has a
Ce support mobile 14 comprend une plaque-support 16
qui porte le porte-capuchon 12 et qui est reliée à une
plaque intermédiaire 18 par une paire de ressorts plats 17
sensiblement parallèles à la direction 15. La plaque
intermédiaire 18 est reliée par une seconde paire de ressorts
plats 19 perpendiculaires à la première paire à une
plaque 20 solidaire du bâti 7 de l'imprimante. Ces deux
paires de ressorts-plats 17 et 19 permettent des mouvements
de translation de la plaque support 16 selon deux
directions perpendiculaires entre elles.This
Pour effectuer la sélection du capuchon 10 ou 11 qui
doit être placé en regard de la tête d'impression 3 ou 2,
la station de maintenance est munie d'un mécanisme de sélection
et de commande 25, comportant un levier palpeur 26
monté pivotant en 27 sur le chariot 1. Ce levier 26 présente
un élément tâteur 28 coopérant avec la tête d'impression
2 ou 3 enfichée. Comme cette tête présente une
forme ou un élément de forme différent pour chaque type de
tête, le levier palpeur 26 occupe une position angulaire
différente selon la tête d'impression enfichée. Ainsi, la
tête d'impression 3 de la figure 4a présente une largeur
plus grande que la tête d'impression 2 de la figure 2a et
le levier est de ce fait pivoté d'un angle de 25° environ
sur le chariot.To select the
Le mécanisme 25 comprend en outre une rampe 30 fixée
sur la plaque-support 16 et susceptible de coopérer avec
un doigt 29 prévu à l'extrémité du levier palpeur 26.
Ainsi, dans le cas de la tête d'impression 2 des figures
3a à 3c, ce doigt 29 entre en contact avec la rampe 30
pour déplacer la plaque-support 16 vers la gauche à la
figure 3b. Au contraire, le doigt 29 passe à côté de la
rampe 30 lorsque la tête d'impression 3 plus large est enfichée
sur le chariot 1 (figures 4a à 4c).The
Le mécanisme 25 présente en plus un poussoir 33 en
forme de dent 34 solidaire du chariot 1 et qui est destiné
à coopérer avec un bossage 35 en forme de came solidaire
de la plaque-support 16. Ce bossage 35 présente deux
flancs de glissement 36 et 37 séparés par une pointe sur
lesquels la dent 34 prend appui lorsque le chariot 1 est
déplacé dans la station de maintenance 6. Ainsi la dent 34
est en regard du flanc 37, lorsque le doigt 29 passe à
côté de la rampe 30 (fig. 4b), et coopère avec ce flanc 37
pour pousser la plaque-support 16 vers la droite à la
figure 4c, pour disposer le capuchon 10 en regard de la
tête d'impression 3.The
Au contraire, lorsque le doigt 29 en coopérant avec la
rampe 30 opère une sélection, la dent 34 entre en contact
avec le flanc 36 et déplace la plaque-support 16 vers la
gauche à la figure 3c pour placer le capuchon 11 en regard
de la tête d'impression 2.On the contrary, when the
Après que la sélection du capuchon 10 ou 11 a été effectuée
par flexion des ressorts-plats 17, le chariot 1
continue sa course en poussant la plaque-support 16 par
l'intermédiaire du poussoir 33 et du bossage 35, les
ressorts-plats 19 sont alors déformés comme cela est montré
à la figure 2b. La distance séparant les plaques 18 et
20 est ainsi raccourcie et la plaque-support 16 et les capuchon
10,11 accomplissent un déplacement oblique vers le
haut en direction de la tête d'impression 2 ou 3 pour solliciter
l'un ou l'autre des capuchons contre la tête d'impression
enfichée.After selection of
Ainsi, le support complexe 14 permet d'accomplir le
déplacement des capuchons en vue de leur sélection et de
leur application contre la tête d'impression par une construction
très simple et ne nécessitant aucun entraínement
particulier, si ce n'est le déplacement du chariot. Lors
de l'enfichage de la tête d'impression sur le chariot 1 le
levier palpeur 26 est amené à une position angulaire prédéterminée
pour coopérer ou non avec la rampe 30 sur la
plaque-support 16 de façon à obtenir la sélection du capuchon
adéquat qui est mis en regard de la tête d'impression.
La translation latérale de la plaque-support est ensuite
effectuée par glissement de la dent 34 le long d'un
des deux flancs du bossage 35. Après cette translation latérale,
le chariot provoque encore l'application du capuchon
sélectionné contre la tête d'impression pour ensuite
être immobilisé dans la station de maintenance avec les
buses recouvertes par le capuchon adéquat. Lors de l'impression
la plaque-support 16 retourne sous l'effet élastique
des ressorts plats 17 et 19 dans sa position initiale
illustrée aux figures 2a, 3a, 4a et 5a.Thus, the
Il est bien entendu que le mode de réalisation décrit
ci-dessus ne présente aucun caractère limitatif et qu'il
peut recevoir toutes modifications désirables à l'intérieur
du cadre tel que défini par la revendication 1. En
particulier, le levier palpeur 26 pourrait être remplacé
par une partie saillante de la tête d'impression agissant
directement sur la rampe 30. Le déplacement de la plaque-support
des capuchons pourrait également se faire par action
directe sur le bossage 35 en forme de came sans présélection
par la rampe et avec ou sans la présence d'un
levier palpeur 26.It is understood that the embodiment described
above is in no way limiting and that it
can receive any desirable modifications inside
of the framework as defined by
Les deux paires de ressorts plats 17 et 19 pourraient
être remplacées par tout autre mécanisme permettant d'effectuer
les mouvements latéraux et d'application des capuchons,
par exemple au moyen des leviers sollicités par des
ressorts vers une position de repos.The two pairs of
On pourrait également réaliser grâce au même principe une variante permettant l'utilisation de trois types différents de têtes d'impression ou davantage.We could also achieve thanks to the same principle a variant allowing the use of three different types or more print heads.
Dans ce cas, la plaque-support 16 porterait un capuchon
central et deux capuchons latéraux par exemple. Le
sens et la grandeur du mouvement de translation perpendiculaire
seront alors définis par le type de tête d'impression
enfiché. Un ou plusieurs capuchons pourraient être
reliés par tube flexible à une pompe d'aspiration permettant
l'amorçage de la tête d'impression ou munis d'un
coussin absorbant l'encre. La station de maintenance pourra
également être équipée d'une ou plusieurs bavettes destinées
à essuyer la partie frontale des têtes d'impression.
Ces bavettes pourraient être montées de façon escamotable
ou non sur le support mobile ou sur le bâti.In this case, the
