Description

Domaine de l'inventionField of the invention

La présente invention concerne les procédés d'impression sur des surfaces rigides ou semi-rigides, par projection d'encre, en proposant un système de positionnement de plusieurs têtes de projection d'encre pour couvrir une largeur d'impression quelconque désirée.The present invention relates to methods for printing on rigid or semi-rigid surfaces, by ink projection, by providing a positioning system of a plurality of ink projection heads to cover any desired printing width.

Etat de l'artState of the art

Pour l'impression sur des surfaces rigides ou semi-rigides, la technique du contact par rouleaux d'impression est connue, ainsi que la technique sans contact par les têtes de projection, cette dernière étant plus perfectionnée et de meilleure qualité pour l'application des encres.For printing on rigid or semi-rigid surfaces, the printing roll contact technique is known, as is the non-contact technique by the projection heads, the latter being more sophisticated and of better quality for the application. inks.

Dans la technique d'impression par projection on utilise cependant des têtes de projection des encres qui sont d'une largeur limitée, de telle sorte que pour couvrir une bande d'impression de largeur supérieure à celle des têtes, il est nécessaire d'utiliser de multiples têtes disposées de telle sorte qu'elles couvrent à elles toutes la largeur de la bande sur laquelle l'impression doit être appliquée.In the projection printing technique, however, ink projection heads are used which are of limited width, so that to cover a printing band of width greater than that of the heads, it is necessary to use multiple heads arranged so that they cover all the width of the band on which the printing is to be applied.

Ladite disposition de plusieurs têtes pour composer une largeur d'impression nécessite dans ce cas un positionnement exact des têtes, pour couvrir toute la largeur de la bande qui doit être imprimée, mais sans accumuler l'encre par recouvrement, afin que la surface imprimée soit uniforme sur toute la largeur, sans rayures longitudinales différenciées du reste.Said arrangement of several heads for composing a printing width requires in this case an exact positioning of the heads, to cover the entire width of the band to be printed, but without accumulating the ink by recovery, so that the printed surface is uniform across the width, without longitudinal stripes differentiated from the rest.

Objet de l'inventionObject of the invention

L'invention propose un système de positionnement des têtes d'impression, dans les machines d'impression par projection mentionnées, selon un mode de réalisation qui résout de façon satisfaisante et simple ledit positionnement des têtes d'impression.The invention proposes a system for positioning the printing heads, in the mentioned projection printing machines, according to a method of which satisfactorily and simply solves said positioning of the print heads.

Selon le système de la présente invention, les multiples têtes destinées à composer une largeur de bande d'impression sont disposées en quinconce en deux files transversales, intégrant en rapport avec chacune des têtes un mécanisme de centrage transversal et un mécanisme de réglage longitudinal, en rapport avec la direction d'application de l'impression qui doit être réalisée.According to the system of the present invention, the multiple heads intended to compose a print bandwidth are staggered in two transverse rows, integrating in relation to each of the heads a transverse centering mechanism and a longitudinal adjustment mechanism, in relationship with the application management of the printing that needs to be done.

Le mécanisme de centrage transversal de chaque tête est composé d'un ressort de poussée de la tête depuis un bord et une vis conique utilisable disposée en rapport avec le côté opposé de la tête, permettant à ladite vis conique, par son actionnement, de pousser la tête contre le ressort de l'autre côté.The transverse centering mechanism of each head is composed of a spring for thrusting the head from an edge and a usable conical screw arranged in relation to the opposite side of the head, allowing said conical screw, by its actuation, to push the head against the spring on the other side.

On obtient ainsi une disposition permettant le déplacement transversal de chaque tête, pour les situer dans la position exacte qui leur correspond, de telle sorte que leurs limites latérales d'impression coïncident avec les limites latérales d'impression des têtes respectives disposées dans la file précédente ou postérieure dans la situation transversale de la bande qui doit être imprimée.An arrangement is thus obtained allowing the transverse displacement of each head, to locate them in the exact position corresponding to them, so that their lateral printing limits coincide with the lateral printing limits of the respective heads arranged in the previous file. or posterior in the transverse situation of the band to be printed.

Le mécanisme de réglage longitudinal de chaque tête est composé à son tour d'un ressort de poussée qui agit sur l'avant de la tête, alors que sur l'autre côté une vis conique utilisable est disposée, grâce à laquelle le déplacement de la tête contre le ressort de l'autre partie est possible.The longitudinal adjustment mechanism of each head is composed in turn of a thrust spring which acts on the front of the head, while on the other side a usable conical screw is arranged, by which the movement of the head against the spring of the other party is possible.

On obtient ainsi une disposition permettant, de la même façon, un déplacement basculant de la tête dans le sens longitudinal selon la direction de l'impression, pour ajuster la position de la tête dans cette direction de façon qu'elle coïncide en parallélisme avec les têtes de la même file.Thus, a provision is obtained allowing, in the same way, a tilting movement of the head in the longitudinal direction in the direction of printing, to adjust the position of the head in this direction so that it coincides in parallel with the heads of the same line.

Les deux mouvements génèrent une combinaison qui permet de positionner, d'une façon très simple, les différentes têtes de projection de l'encre dans chaque impression d'application, pour ajuster avec précision la localisation nécessaire de chacune des têtes en rapport avec les autres pour obtenir une impression totalement uniforme.The two movements generate a combination that makes it possible to position, in a very simple way, the different ink projection heads in each application print, to precisely adjust the necessary location of each of the heads in relation to the others. to get a totally uniform impression.

La répartition des têtes de la façon indiquée entraîne également une séparation entre elles qui permet d'intégrer les mécanismes de positionnement sans préjudice pour la fonction d'impression qui doit être réalisée par l'ensemble des têtes utilisées.The distribution of the heads in the manner indicated also leads to a separation between them which makes it possible to integrate the positioning mechanisms without prejudice to the printing function that must be performed by all the heads used.

Grâce à tout cela, le système selon l'invention offre des caractéristiques certainement avantageuses, de préférence pour la fonction de réglage de l'impression par composition sur des bandes par l'intermédiaire de multiples têtes de projection d'encre.Thanks to all this, the system according to the invention offers certainly advantageous features, preferably for the function of adjusting the composition printing on strips via multiple ink projection heads.

Description détaillée de l'inventionDetailed description of the invention

L'objet de l'invention concerne un système de positionnement des têtes dans les machines d'impression par projection qui utilisent un ensemble de têtes pour chaque couleur d'encre pour couvrir la largeur de la bande d'impression, disposant les têtes (1) de chaque groupe d'impression en deux files transversales parallèles, selon une distribution en quinconce, ainsi que cela est illustré sur la figure 1.The object of the invention is a head positioning system in projection printing machines which uses a set of heads for each ink color to cover the width of the printing tape, arranging the heads (1 ) of each printing unit into two parallel transverse lines, in a staggered distribution, as shown in FIG. figure 1 .

Par l'intermédiaire de cette distribution, en disposant le nombre de têtes (1) nécessaire, il est possible de couvrir une largeur quelconque de bande d'impression, en devant faire coïncider de façon exacte les limites de la zone (2) d'impression des têtes (1) correspondantes des deux files de la distribution, pour que l'impression soit uniforme sur toute la largeur.Through this distribution, by arranging the necessary number of heads (1), it is possible to cover any width of printing band, having to exactly coincide the limits of the area (2) of printing the corresponding heads (1) of the two rows of the distribution, so that the printing is uniform over the entire width.

Cela nécessite un positionnement corrélatif des têtes (1) selon le type d'encre à appliquer et les paramètres de la projection d'application, et donc selon le système de l'invention on dispose en rapport avec chaque tête (1) un mécanisme de centrage transversal et un mécanisme de réglage longitudinal, par rapport à la direction de l'impression, permettant la distribution en quinconce de l'ensemble des têtes (1), en deux files parallèles, une séparation entre les têtes (1) distinctes, qui permet d'incorporer entre elles les mécanismes mentionnés.This necessitates a correlative positioning of the heads (1) according to the type of ink to be applied and the parameters of the application projection, and therefore according to the system of the invention there is arranged in relation to each head (1) a mechanism of transverse centering and a longitudinal adjustment mechanism, with respect to the direction of printing, allowing the staggered distribution of all the heads (1) in two parallel rows, a separation between the heads (1) distinct, which allows to incorporate the mentioned mechanisms.

Le mécanisme de centrage transversal (1) est composé, ainsi que cela est illustré sur les figures 2 et 3, d'un ressort de poussée (3) qui agit sur un côté de la tête (1) correspondante, alors qu'une vis conique (4) est disposée sur l'autre côté, par l'intermédiaire de laquelle il est possible de réaliser une poussée de la tête (1) contre le ressort (3).The transverse centering mechanism (1) is composed, as is illustrated on the Figures 2 and 3 a thrust spring (3) which acts on one side of the corresponding head (1), while a conical screw (4) is arranged on the other side, through which it is possible to carry out a thrust of the head (1) against the spring (3).

De la sorte, par la combinaison de la poussée du ressort (3) et de l'actionnement de la vis conique (4), il est possible de réaliser un déplacement (5) de la tête (1) pour la situer correctement en correspondance des têtes respectives de la file précédente ou postérieure de la distribution transversale dans la bande d'impression qui doit être réalisée.In this way, by the combination of the thrust of the spring (3) and the actuation of the conical screw (4), it is possible to make a displacement (5) of the head (1) to locate it correctly in correspondence respective heads of the previous or subsequent file of the transverse distribution in the print band to be performed.

Le mécanisme de réglage longitudinal (figure 4) est composé à son tour d'un ressort (6) qui agit à l'avant de la tête (1) correspondante, alors que sur l'autre côté une vis conique (7) est également disposée, par l'intermédiaire de laquelle il est possible de réaliser à son tour une poussée de la tête (1) contre le ressort (6).The longitudinal adjustment mechanism ( figure 4 ) is composed in turn of a spring (6) which acts in front of the corresponding head (1), while on the other side a conical screw (7) is also arranged, through which it is possible to realize in turn a thrust of the head (1) against the spring (6).

De cette façon, par la combinaison de la poussée du ressort (6) et de l'actionnement de la vis conique (7), il est possible de réaliser un déplacement (8) de basculement de la tête (1) dans le sens longitudinal, pour la situer de façon correspondante en parallèle avec le reste des têtes (1) de la même file.In this way, by the combination of the thrust of the spring (6) and the actuation of the conical screw (7), it is possible to make a displacement (8) of tilting of the head (1) in the longitudinal direction , to locate it correspondingly in parallel with the rest of the heads (1) of the same queue.

La combinaison des deux mouvements de réglage mentionnés permet de situer avec précision chacune des têtes (1) de l'ensemble d'impression, dans chaque application, pour le développement d'une impression parfaitement uniforme.The combination of the two adjustment movements mentioned makes it possible to precisely locate each of the heads (1) of the printing assembly, in each application, for the development of a perfectly uniform printing.

Le fonctionnement des têtes (1) est susceptible d'être régi par un logiciel de commande, pour retarder ou avancer le début du fonctionnement de la projection d'encre de chacune des têtes (1) quand elle correspond, pouvant ainsi obtenir une impression parfaite.The operation of the heads (1) is likely to be governed by a control software, to delay or advance the start of the operation of the ink projection of each of the heads (1) when it corresponds, thus obtaining a perfect impression .

Les têtes (1) sont également installées dans un montage à basculement vertical, au travers duquel elles peuvent être installées à partir d'une position de projection verticale, dans une position de projection horizontale, pour réaliser une projection d'impression sur toute la surface d'une quelconque pièce (9) d'application, ainsi que cela est illustré sur la figure 4 ; il est possible d'établir la position de l'une quelconque des têtes (1) dans un angle (β) d'inclinaison variable, pour obtenir l'incidence de la projection dans des zones (10) sur lesquelles la projection verticale ne parvient pas à entrer en contact correctement, ainsi que cela est illustré sur la figure 5.The heads (1) are also installed in a vertical tilt arrangement, through which they can be installed from a vertical projection position, in a horizontal projection position, to effect full-surface printing projection. any part (9) of application, as is illustrated on the figure 4 ; it is possible to establish the position of one any of the heads (1) in a variable inclination angle ( β ), to obtain the incidence of the projection in areas (10) over which the vertical projection can not come into proper contact, as illustrated. on the figure 5 .
