Definitions
- the invention is in the field of thermal printing machines. Its subject is a printing module for a mechanism
- the 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
- a thermal printing module 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
- control electronic means for controlling the operation of the printing module.
- 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.
- these faults are a choice of designers, but that usually these identified faults include at least a detection of overheating of the line of points.
- 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.
- a problem is the ease offered for maintenance, and more particularly the interchangeability, of the printing module in the event of a breakdown.
- 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.
- 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.
- 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.
- one solution is to organize the connector of the printing module with the connector assigned to the machine.
- 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.
- Another solution is to use connectors lock-tuning forLe entreie ⁇ cable in iHppe ⁇ ⁇ équipa ⁇ t the print module and the machine.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- FIG. 1 is a perspective view of a thermal printing module according to a first embodiment of the invention
- FIG. 2 is a perspective view of a thermal printing module according to a second alternative embodiment of the invention
- fig.3 is a logic diagram of the operation of security means fitted to any of the modules respectively illustrated in fig.1 and fig. 2.
- a thermal printing module is composed of a radiator 1 on which is fixed:
- 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).
- the connector at least assigned to the module is any one at least of a group of connectors comprising a connector 7 connected directly to the module and cooperating with a connector fitted to the ribbon cable (not shown in the figures), in the case of the variant illustrated in fig.1, and / or a connector 14 fitted to the ribbon cable 13 and cooperating with a complementary connector commonly fitted to the machine.
- the security means include:
- this first group of means comprising:
Landscapes
- Accessory Devices And Overall Control Thereof (AREA)
