L'invention est du domaine des machines à impression thermique. Elle a pour objet un module d'impression pour mécanismeThe invention is in the field of thermal printing machines. Its subject is a printing module for a mechanism
10 d'impression thermique équipant de telles machines, étiqueteuses notamment.10 thermal printing equipping such machines, labeling machines in particular.
Les machines à impression thermique sont équipées d'un mécanisme d'impression pour le marquage par chauffage d'une bande à imprimer conditionnée en rouleau. Le mécanisme d'impression comprend un châssis, qui supporte des moyens d'entraînement de la bande par défilement àThe thermal printing machines are equipped with a printing mechanism for marking by heating a strip to be printed conditioned in a roll. The printing mechanism comprises a frame, which supports means for driving the strip by scrolling at

Ce dernier comporte des moyens électroniques d'activation d'au moins une ligne de points chauffants pour le marquage de la bande, qui est ménagée sur un substrat en céramique ou analogue, et des moyens de commande pour la mise en oeuvre de ces moyens d'activation. On notera que les moyens d'activation de la ligne de points sont15 through a thermal printing module. The latter comprises electronic means for activating at least one line of heating points for marking the strip, which is formed on a ceramic or similar substrate, and control means for the implementation of these means. activation. Note that the means of activating the line of points are
20 avantageusement directement rapportés sur le substrat en céramique. On notera aussi qu'en raison de l'environnement chauffant inhérent au caractère thermique du module, il est nécessaire de prévoir l'installation sur celui-ci d'un radiateur.20 advantageously directly attached to the ceramic substrate. Note also that due to the heating environment inherent in the thermal nature of the module, it is necessary to provide for the installation thereon of a radiator.
La fragilité des organes électroniques du module, et notamment de la ligne de points, rend nécessaire d'adjoindre aux moyens deThe fragility of the electronic components of the module, and in particular of the line of points, makes it necessary to add to the means of
25 commande, des moyens électroniques de contrôle du fonctionnement du module d'impression. Ces moyens de contrôle sont associés à des moyens de rupture d'un flux électrique vers le module d'impression, pour qu'en cas de défauts identifiés détectés, l'alimentation en puissance de la ligne de points et/ou la commande de leur activation soient interrompues. On relèvera que l'identification25 control, electronic means for controlling the operation of the printing module. These control means are associated with means for breaking an electrical flow to the printing module, so that in the event of identified identified faults, the power supply to the line of dots and / or the control of their activation are interrupted. It should be noted that the identification
30 de ces défauts relève d'un choix des concepteurs, mais que de manière habituelle ces défauts identifiés comprennent au moins une détection d'une surchauffe de la ligne de points. Par ailleurs, la recherche d'une réduction de l'encombrement du mécanisme d'impression conduit naturellement les concepteurs à disposer le plus grand nombre possible d'organes sur la machine, et notamment la réserve en rouleau de la bande à imprimer et les moyens de commande du module d'impression. Le module est donc équipé de moyens de raccordement électrique entre les moyens d'activation de la ligne de points et les moyens distants de commande et de contrôle, localisés sur la machine.30 of these faults is a choice of designers, but that usually these identified faults include at least a detection of overheating of the line of points. In addition, the search for a reduction in the size of the printing mechanism naturally leads designers to place as many organs as possible on the machine, and in particular the roll reserve of the strip to be printed and the means the print module. The module is therefore equipped with electrical connection means between the means for activating the line of points and the remote command and control means, located on the machine.
Une solution avantageuse consiste à pourvoir le module d'un câble en nappe pour un tel raccordement. On notera que de manière analogue, ce câble est relié aux moyens d'activation de la ligne de points du module, soit directement par fixation, par soudage notamment, soit par l'intermédiaire d'un jeu de connecteurs.An advantageous solution consists in providing the module with a ribbon cable for such a connection. It will be noted that in a similar manner, this cable is connected to the means for activating the line of points of the module, either directly by fixing, in particular by welding, or by means of a set of connectors.
Un problème posé réside dans la facilité offerte pour la maintenance, et plus particulièrement l'interchangeabilité, du module d'impression en cas de panne. Pour cela, il a été proposé par l'art antérieur de raccorder entre eux la machine et le câble en nappe équipant le module, par l'intermédiaire d'un jeu de connecteurs qui leurs sont respectivement affectés. Il en résulte une facilité de rupture de la liaison entre le module et la machine.A problem is the ease offered for maintenance, and more particularly the interchangeability, of the printing module in the event of a breakdown. For this, it has been proposed by the prior art to connect the machine and the ribbon cable equipping the module, by means of a set of connectors which are respectively assigned to them. This results in easy breakage of the connection between the module and the machine.
Cependant, il est apparu à l'usage qu'une fragilité mécanique du module d'impression n'était pas en adéquation avec les habitudes prises quant à l'utilisation des machines d'impression thermique, notamment celles sujettes à être manipulées fréquemment dans des conditions mécaniquement hostiles, telles que des étiqueteuses. Plus précisément, leur manipulation brusque et les chocs auxquels elles sont susceptibles d'être soumises, tendent à rompre la qualité du raccordement entre les connecteurs respectivement affectés au module d'impression et à la machine. Il est en outre fréquent que ce raccordement ne soit pas effectué correctement, lors d'une opération de maintenance notamment.However, it has become apparent from use that a mechanical fragility of the printing module is not in line with the habits adopted with regard to the use of thermal printing machines, in particular those subject to being handled frequently in mechanically hostile conditions, such as labellers. More precisely, their rough handling and the shocks to which they are likely to be subjected tend to break the quality of the connection between the connectors respectively assigned to the printing module and to the machine. It is also frequent that this connection is not carried out correctly, in particular during a maintenance operation.
Il en découle un dysfonctionnement de l'activation de la ligne de points et un contrôle aléatoire du fonctionnement du module d'impression, avec pour conséquence un risque de détérioration de la ligne de points, voire du module d'impression dans sa globalité. Une solution consiste donc à raccorder directement par soudage le câble en nappe équipant le module d'impression aux moyens de commande et de contrôle localisés sur la machine. Cependant, cette solution est choisie au détriment de la facilité susvisée de la maintenance et de l'interchangeabilité du module d'impression en cas de panne ou de détérioration.This results in a malfunction of the activation of the dot line and a random check of the operation of the printing module, with the consequence of a risk of deterioration of the dot line, or even of the printing module as a whole. One solution therefore consists in directly connecting by welding the ribbon cable equipping the printing module with the command and control means located on the machine. However, this solution is chosen to the detriment of the above-mentioned ease of maintenance and the interchangeability of the printing module in the event of failure or deterioration.
Une autre solution consiste à pourvoir le raccordement mécanique entre les connecteurs affectés au module d'impression et à la machine, de moyens mécaniques garantissant la fiabilité de ce raccordement. Par exemple, une solution consiste à organiser en détrompeur le connecteur du module d'impression avec celui affecté à la machine. Cependant, cette solution reste insuffisante, en raison du fait que ce détrompeur ne garantit en rien une continuité de la qualité du raccordement, susceptible d'être altérée suite à des gestes brusques ou des chocs lors de l'utilisation de la machine.Another solution consists in providing the mechanical connection between the connectors assigned to the printing module and to the machine, with mechanical means guaranteeing the reliability of this connection. For example, one solution is to organize the connector of the printing module with the connector assigned to the machine. However, this solution remains insufficient, due to the fact that this keying device does not in any way guarantee continuity of the quality of the connection, liable to be altered following abrupt gestures or shocks during the use of the machine.
Une autre solution encore consiste à utiliser des connecteurs à verrouillage-pourle accordement entreie~câble-en iHppe~équipaπt~ le module d'impression et la machine.Another solution is to use connectors lock-tuning forLe entreie ~ cable in iHppe ~ ~ équipaπt the print module and the machine.
Une solution aussi pratiquée à l'usage, consiste à coller ensemble les connecteurs, ce qui n'est guère opportun en raison du fait que cette solution ne facilite pas la maintenance du module d'impression.A solution also practiced in use, consists in bonding the connectors together, which is hardly expedient due to the fact that this solution does not facilitate maintenance of the printing module.
Il apparaît donc qu'un compromis doit être trouvé entre la fiabilité du raccordement entre le câble en nappe équipant le module d'impression et la machine, et paradoxalement la facilité offerte de rupture de ce raccordement en vue de faciliter la maintenance du module d'impression, dans un cadre de contraintes liées à une limitation de l'encombrement et du coût d'obtention du module d'impression.It therefore appears that a compromise must be found between the reliability of the connection between the ribbon cable equipping the printing module and the machine, and paradoxically the ease of breaking this connection in order to facilitate the maintenance of the module. printing, within the framework of constraints linked to a limitation of the size and the cost of obtaining the printing module.
Le but de la présente invention est de proposer un module d'impression pour machine à impression thermique, qui soit d'un encombrement restreint et qui soit néanmoins organisé pour résoudre le problème lié au raccordement entre eux des connecteurs respectivement affectés au module d'impression et à la machine. La démarche inventive de la présente invention a consisté dans sa globalité à faire un choix inhabituel dans le domaine, qui consiste à palier aux conséquences d'un raccordement défectueux entre les connecteurs respectivement affectés au module d'impression et à la machine, en intervenant directement sur l'activation en puissance de la ligne de point et/ou la commande de cette activation, en cas d'un tel raccordement défectueux.The aim of the present invention is to propose a printing module for a thermal printing machine, which is of a small size and which is nevertheless organized to solve the problem linked to the connection between them of the connectors respectively assigned to the printing module. and machine. The inventive step of the present invention consisted in its entirety in making an unusual choice in the field, which consists of overcoming the consequences of a defective connection between the connectors respectively assigned to the printing module and to the machine, by intervening directly. on the power activation of the point line and / or the control of this activation, in the event of such a defective connection.
La détection de ce raccordement défectueux est obtenue par une localisation sur le module de moyens électroniques de sécurisation, en interposition entre le connecteur affecté au module et les moyens d'activation de la ligne de points, de telle sorte qu'une commande et/ou une alimentation en puissance non conforme du module d'impression en provenance de la machine, résultant d'un raccordement défectueux entre les connecteurs, provoque une interruption concomitante d'un flux électrique vers la ligne de points. On comprendra que dans le cadre de la démarche inventive de la présente invention, et du problème spécifique qu'elle cherche à résoudre, les moyens susvisés de sécurisation du module d'impression, qui constituent des moyens de détection d'un raccordement défectueux entre les connecteurs, sont aptes de fonctionner tant en complément qu'en substitution des moyens de contrôle habituellement intégrés à distance aux moyens de commande localisés sur la machine.The detection of this faulty connection is obtained by localization on the module of electronic security means, interposed between the connector assigned to the module and the means of activating the line of dots, so that a command and / or a non-compliant power supply to the printing module from the machine, resulting from a faulty connection between the connectors, causes a concomitant interruption of an electrical flow to the line of dots. It will be understood that in the context of the inventive step of the present invention, and of the specific problem which it seeks to solve, the abovementioned means of securing the printing module, which constitute means for detecting a defective connection between the connectors, are able to function both in addition to and in substitution for the control means usually integrated remotely to the control means located on the machine.
Ainsi le module d'impression thermique de la présente invention comporte : *- des moyens électroniques d'activation d'au moins une ligne de points chauffants pour le marquage d'une bande à imprimer, ligne de points ménagée sur un substrat en céramique ou analogue.Thus the thermal printing module of the present invention comprises: * - electronic means for activating at least one line of heating points for marking a strip to be printed, line of points formed on a ceramic substrate or similar.
*- un câble en nappe pour le raccordement électrique entre les moyens électroniques d'activation de la ligne de points, et des moyens distants de commande localisés sur une machine d'impression prévue pour être équipée du module, et* a ribbon cable for the electrical connection between the electronic means for activating the line of points, and remote control means located on a printing machine intended to be equipped with the module, and
*- au moins un jeu de connecteurs coopérants, ou analogues, respectivement affectés au module et à la machine pour leur raccordement par l'intermédiaire du câble en nappe. On notera à ce stade de la description que selon des caractéristiques secondaires du module d'impression de l'invention, les moyens électroniques d'activation de la ligne de points sont rapportés sur le substrat, et qu'un radiateur est installé sur le module d'impression. * - at least one set of cooperating connectors, or the like, respectively assigned to the module and to the machine for their connection by means of the ribbon cable. It will be noted at this stage of the description that according to secondary characteristics of the printing module of the invention, the electronic means for activating the line of dots are attached to the substrate, and that a radiator is installed on the module printing.
Selon la présente invention, un tel module est principalement reconnaissable en ce qu'il comporte, en interposition entre les moyens d'activation de la ligne de points et le connecteur affecté au module pour son raccordement à un connecteur complémentaire affecté à la machine, des moyens électroniques de sécurisation de son fonctionnement par rupture d'un flux électrique, tel que de puissance et/ou de commande, vers les moyens d'activation de la ligne de points, en cas d'une information non pertinente de fonctionnement.According to the present invention, such a module is mainly recognizable in that it comprises, in interposition between the means for activating the line of points and the connector assigned to the module for its connection to an additional connector assigned to the machine, electronic means for securing its operation by breaking an electrical flow, such as power and / or control, to the activation means of the line of points, in the event of irrelevant operating information.
Ces moyens de sécurisation sont plus particulièrement des moyens de contrôle de l'activation de l'un quelconque au moins des points de la ligne de points, en aval du connecteur affecté au module, pour prendre en compte un dysfonctionnement éventuel du raccordement mécanique entre ce connecteur et celui affecté à la machine.These securing means are more particularly means for controlling the activation of any at least of the points of the line of points, downstream of the connector assigned to the module, to take into account a possible malfunction of the mechanical connection between this connector and the one assigned to the machine.
On comprendra notamment par rupture d'un flux électrique l'une quelconque au moins des ruptures de flux comprenant une rupture de l'alimentation en puissance de la ligne de points et une rupture d'un signal de commande de l'activation de l'un quelconque au moins de ces points.It will be understood in particular by breaking of an electrical flow at least any one of breaks in flow comprising a break in the power supply of the line of points and a break in a signal for controlling the activation of the at least any of these points.
Plus précisément, les moyens de sécurisation du module sont l'un quelconque au moins : *- de moyens de sécurisation comprenant des moyens de rupture d'un signal de commande de l'activation de la ligne de points et/ou de rupture de l'alimentation électrique de puissance du module, placés sous la dépendance de moyens de détection d'une activation trop longue de la ligne de points, et *- de moyens de rupture de l'alimentation électrique de puissance du module, placés sous la dépendance de moyens de détection d'une absence de tension logique du module.More specifically, the module securing means are at least any one: * - securing means comprising means for breaking a command signal for activating the line of points and / or breaking the line power supply of the module, placed under the dependence of means for detecting a too long activation of the point line, and * - means of breaking the power supply of the module, placed under the dependence of means for detecting an absence of logic voltage from the module.

Ces moyens de raccordement mettent en œuvre un câble en nappe 13, seulement visible sur la fig.2, et au moins un jeu de connecteurs coopérant respectivement affectés au module et à la machine. Ce câble en nappe 13 est indifféremment raccordé au module, soit tel qu'illustré sur la variante de la fig.1 par l'intermédiaire d'un connecteur annexe 7, coopérant avec un connecteur complémentaire équipant le câble en nappe, non visibles sur cette figure, soit directement par soudage, tel qu'illustré sur la variante de la fig.2, le connecteur affecté dans ce cas au module étant un connecteur 14 équipant le câble en nappe 13 qui coopère avec un connecteur complémentaire équipant la machine (non représenté sur la figure). On comprendra donc que le connecteur au moins affecté au module est l'un quelconque au moins d'un groupe de connecteurs comprenant un connecteur 7 relié directement au module et coopérant avec un connecteur équipant le câble en nappe (non représentés sur les figures), dans le cas de la variante illustrée sur la fig.1 , et/ou un connecteur 14 équipant le câble en nappe 13 et coopérant avec un connecteur complémentaire équipant de manière courante la machine. En se reportant plus particulièrement sur la fig.3, les moyens de sécurisation comprennent :These connection means implement a ribbon cable 13, only visible in FIG. 2, and at least one set of cooperating connectors respectively assigned to the module and to the machine. This ribbon cable 13 is indifferently connected to the module, either as illustrated in the variant of FIG. 1 via an annex connector 7, cooperating with a complementary connector fitted to the ribbon cable, not visible on this figure, either directly by welding, as illustrated in the variant of FIG. 2, the connector assigned in this case to the module being a connector 14 fitted to the ribbon cable 13 which cooperates with a complementary connector fitted to the machine (not shown on the face).
