Abstract

The method for the control of a printing head comprises the formation of printing subsystems (M1, M2, M3) each comprised of a supply block (CE) to which are associated, within the subsystem in question, one, two or three heads (T) provided with a proper computation unit and having similar or different characteristics. A bus (10) interconnects on one hand said subsystems, and on the other hand the supply blocks (CE) and the heads (T). The bus (10) also connects the assembly to a control console (30) which is itself connected with a host computer (40). It may also connect the assembly optionally to external information means such as a video camera (50) or a laser reader (51). The invention may be applied to the installation of flexible printing workshops.

Description

PROCEDE DE COMMANDE DE TETE D'IMPRESSION PRINTHEAD CONTROL METHOD
A JET D'ENCRE ET ATELIER FLEXIBLEINKJET AND FLEXIBLE WORKSHOP
AINSI EQUIPESO EQUIPPED
L'invention concerne un procédé de commande de tête d'impression à jet d'encre. Elle concerne également tout atelier flexible équipé selon ce procédé- La technique dit du jet d'encre permet une grande variété de carac- tères d'impression, tant sur le plan de la finesse des caractères que sur celui de la couleur ou du nombre de jets. De plus, elle permet de marquer pratiquement tout type de support quelque soit sa forme, sa nature ou sa dimension.The invention relates to a method for controlling an ink jet print head. It also concerns any flexible workshop equipped according to this process. The so-called inkjet technique allows a wide variety of printing characteristics, both in terms of the smoothness of the characters and in terms of color or number of jets. In addition, it makes it possible to mark practically any type of support whatever its shape, its nature or its size.
Cependant, un gros problème se pose des lors que l'on veut comman¬ o der à distance une ou plusieurs têtes d'i mpres.sion. On peut alors avoir recours à un procédé de commande centralisée dont la structure de mise e.n oeuvre peut être qualifiée d'arborescente. Un tel procédé conduit à des installations extrêmement lourdes, coûteuses et difficiles à piloter.However, a big problem arises when we want to remotely control one or more heads of i mpres.sion. We can then have recourse to a centralized control method whose implementation structure can be described as tree-like. Such a process leads to extremely heavy, costly and difficult to control installations.
La présente invention a pour but de pallier ces inconvénients et 5 concerne un procédé de commande qui permet d'associer un nombre théori¬ quement infini de têtes d'écriture indépendantes et de les programmer à partir d'un point d'entrée unique ou non.The present invention aims to overcome these drawbacks and relates to a control method which makes it possible to associate a theoretically infinite number of independent writing heads and to program them from a single entry point or not .
Elle concerne plus précisément un procédé de commande d'une pluralité de têtes d'impression, caractérisé en ce qu'il consiste à créer f) des "sous-systèmes" d'impression constitués d'un "bloc d'alimentation" d'au moins une "tête d'impression", la liaison entre les "sous-systèmes" d'une part, entre le "bloc d'alimentation" cl les "têtes d'impression" d'autre part, un clavier de commande de l'ensemble et un calculateur extérieur, étant faite par un bus. 5 L'invention concerne également tout atelier flexible d'impression mettant en oeuvre une pluralité de tels sous-systèmes d'impression.It relates more precisely to a method for controlling a plurality of printheads, characterized in that it consists in creating f) printing "subsystems" consisting of a "power supply" of at least one "print head", the link between the "subsystems" on the one hand, between the "power supply" and the "print heads" on the other hand, a keyboard for controlling the assembly and an external computer, being made by a bus. The invention also relates to any flexible printing workshop using a plurality of such printing subsystems.
L'invention sera mieux comprise à l'aide des explications qui vont suivre et des figures jointes parmi lesquelles :The invention will be better understood with the aid of the explanations which follow and of the appended figures among which:
La figure 1 illustre schématiquement une architecture de moyens Q mettant en oeuvre un procédé conforme à l'invention. La figure 2 illustre un bus tel qu'utilisé conformément à l'invention. Le procédé conforme à l'invention illustré au moyen des figures 1 et 2, consiste à créer des sous-systèmes dit "sous-systèmes d'impression" dans la suite de la description et référencé (M) de manière générale avec ou sans indice. Chacun de ces sous-systèmes d'impression (M) est essentiel¬ lement constitué d'un "bloc d'alimentation" (CE) assurant l'alimentation électrique et en encre d'au moins une "tête d'impression" (T) qui, selon une caractéristique de l'invention, est dotée d'une unité de calcul (TC) qui lui est propre. Dans la figure 1, on a représenté à titre d'exemple non limitatif, trois types de tels sous-systèmes d'impression .(M). L'un référencé (Ml) comporte une seule tête (T). L'autre référencé (M2) comporte deux têtes (T). Le troisième référencé (M3) comporte trois têtes (T).FIG. 1 schematically illustrates an architecture of means Q implementing a method according to the invention. FIG. 2 illustrates a bus as used in accordance with the invention. The method according to the invention illustrated by means of FIGS. 1 and 2, consists in creating subsystems called "printing subsystems" in the following description and referenced (M) generally with or without index . Each of these printing subsystems (M) is essentially made up of a "power supply unit" (CE) ensuring the electrical supply and ink of at least one "print head" (T ) which, according to a characteristic of the invention, is provided with its own calculation unit (TC). In Figure 1, there is shown by way of non-limiting example, three types of such printing subsystems. (M). The one referenced (Ml) has a single head (T). The other referenced (M2) has two heads (T). The third referenced (M3) has three heads (T).
Selon une caractéristique importante de l'invention, au sein même d'un sous-système d'impression (M), les têtes d'impression (T) peuvent présenter des caractéristiques identiques ou différentes portant notamment sur la taille et la finesse des caractères, sur la couleur et sur le nombre de jets associés dans la même tête...According to an important characteristic of the invention, within a printing subsystem (M), the printheads (T) may have identical or different characteristics relating in particular to the size and the fineness of the characters , on the color and on the number of associated jets in the same head ...
Conformément à l'invention, la liaison entre les sous-systèmes (M) d'une part, "le bloc d'alimentation et les têtes d'impression" d'autre part, est assurée au moyen d'un bus 10. Ce dernier est d'un type classique à deux torsades 11 et 12, l'une dite "paire donnée" et l'autre "paire mise sous tension", blindées dans une gaine 13.According to the invention, the connection between the subsystems (M) on the one hand, "the power supply and the print heads" on the other hand, is ensured by means of a bus 10. This the latter is of a conventional type with two twists 11 and 12, one known as a "given pair" and the other a "tensioned pair", shielded in a sheath 13.
Selon une caractéristique de l'invention, il est possible de réaliser ainsi des ateliers flexibles d'impression et d'adapter le nombre et les carac¬ téristiques de chaque sous-système d'impression (M) aux applications consi¬ dérées. Ces sous-systèmes reliés entre eux en série par le bus 10, peuvent être espacés les uns des autres sur des distances pouvant aller jusqu'à 500 mètres. Le bus 10 relie l'ensemble défini précédemment à une console de commande 30 constituée par exemple d'un clavier 31, lui-même relié par ledit bus à un module 32 d'interface entrée-sortie E/S, associé à un calcula¬ teur extérieur 40 dit ordinateur hôte. Chacun des dispositifs commandés par le bus 10 est doté de manière connue d'un circuit d'interface bus (non représenté).According to a characteristic of the invention, it is thus possible to produce flexible printing workshops and to adapt the number and the characteristics of each printing subsystem (M) to the applications considered. These subsystems connected together in series by bus 10, can be spaced from each other over distances of up to 500 meters. The bus 10 connects the assembly defined above to a control console 30 consisting for example of a keyboard 31, itself connected by said bus to a module 32 of I / O input / output interface, associated with a calcula¬ outside designer 40 says host computer. Each of the devices controlled by the bus 10 is provided in a known manner with a bus interface circuit (not shown).
Selon une autre caractéristique de l'invention et comme le montre la figure 1, dans le cadre de variantes de réalisation, en série avec les moyens de commande (console 30 - ordinateur 40) et les sous-systèmes d'impression (M), peuvent être montés des moyens d'informations autres que les moyens d'impression et qui peuvent réagir sur eux. Par exemple on a représenté sur la figure 1, une caméra vidéo 50, destinée à lire direc¬ tement les caractères imprimés et un lecteur Laser 51 capable de lire un code barres.According to another characteristic of the invention and as shown Figure 1, in the context of alternative embodiments, in series with the control means (console 30 - computer 40) and the printing subsystems (M), can be mounted information means other than the means who can react on them. For example, there is shown in FIG. 1, a video camera 50, intended for reading directly the printed characters and a Laser reader 51 capable of reading a bar code.
Des bouchons 60, 61 placés à l'entrée et à la sortie permettent de fermer et d'accorder l'impédance du bus 10. La présente invention présente de nombreuses applications nota - ment chaque fois où il convient de regrouper par une, deux ou trois, les têtes d'impression sur les mêmes lignes de produits à marquer ou sur des lignes différentes. Elle permet un espacement relativement important entre les différents modules de marquage. Plugs 60, 61 placed at the input and at the output make it possible to close and tune the impedance of the bus 10. The present invention has numerous applications, particularly whenever it is advisable to group by one, two or three, the print heads on the same lines of products to be marked or on different lines. It allows a relatively large spacing between the different marking modules.
