Here, the movable positioning member 14 described above will be described in detail.

3A is a perspective view around the movable positioning member 14, and FIG. 3B is a cross-sectional view around the movable positioning member 14.

As shown in FIGS. 3A and 3B, the slider 15 coupled to the movable positioning member 14 has a fixing mechanism 16 for fixing the movable positioning member 14 moved along the guide shafts 13, 13. have. The fixing mechanism 16 is fixed to the fixing screw 16a and the guide shaft 13, and is fixed to the linear bush 15a provided so as to be movable back and forth along the guide shafts 13 and 13, and to the lower end of the fixing screw 16a. The shaft 13 has a slide block 16b which is penetrated with a predetermined gap.

By rotating the fixing screw 16a, the user also raises the slide block 16b fixed to the lower end of the fixing screw 16a in the Z1 direction. As a result, the inscribed portion 16b1 of the slide block 16b comes into contact with the guide shaft 13, and the slider 15 is fixed by the friction caused by this contact, so that the movable positioning member 14 coupled to the slider 15 is also fixed.

Further, the user rotates the fixing screw 16a in the opposite direction, so that the slide block 16b fixed to the lower end portion of the fixing screw 16a also descends in the Z2 direction. As a result, the fixing of the slider 15 is released, so that the movable positioning member 14 connected to the slider 15 is also released.

In this way, the movable positioning member 14 is fixed or released from being fixed by a user operation. Therefore, there is a possibility that fixing of the movable positioning member 14 may be insufficient due to insufficient rotation of the fixing screw 16a by the user, or the user may forget to fix the movable positioning member 14.

When the movable positioning member 14 is not sufficiently fixed in this way, when the thermal head 32 is heated and punched while moving the thermal head 32 in the X1 direction (from the front end side to the rear end side) on the movable positioning member 14 side, the gauze frame 21 May shift to the movable positioning member 14 side (X1 side).

If the thermal head 32 heats and punches the gauze frame 21 in a state where the gauze frame 21 is displaced to the movable positioning member side (X1 side), the heat sensitive gauze 22 cannot be heat punched and the heat sensitive gauze 22 is wasted. It will be.

Therefore, in the present embodiment, a plurality of heating elements 32a arranged in the Y direction, which is the main scanning direction, while the thermal head 32 and the platen roller 42 are moved in the X2 direction, which is the sub scanning direction, are selectively selected based on the image data. The plate is perforated with an image on the heat-meltable film of the heat-sensitive cloth 22 by driving to heat.

FIG. 4 is a diagram showing a functional configuration of the thermal plate making apparatus 10 according to the present embodiment of the present invention.

As shown in FIG. 4, the thermal plate making apparatus 10 includes a control unit 60, a display unit 80, a head unit 30, a platen unit 40, and a sensor 35. The head portion 30, the platen portion 40, and the sensor 35 have been described above, and thus description thereof will be omitted.

The display unit 80 is an image output device such as an organic EL (electroluminescence) display or a liquid crystal display, and displays an error message or the like based on the output signal supplied from the control unit 60.

The control unit 60 performs central control of the thermal plate making apparatus 10.

For example, the control unit 60 includes a job acquisition unit 61, a calculation unit 62, an abnormality determination unit 63, and a plate making control unit 64.

The job acquisition unit 61 acquires a job generated by, for example, a PC (personal computer) (not shown) connected via a network. The acquired job includes image data, the size (width and length) of plate making, the size (width and length) of the gauze frame, and the like.

The calculation unit 62 calculates the movement amount of the thermal head 32 based on the job acquired by the job acquisition unit 61. For example, the calculation unit 62 extracts the length of plate making from the job.

When the rear end of the gauze frame 21 is detected by the sensor 35 while the thermal head 32 is moving in the X1 direction by the amount of movement calculated by the calculating part 62, the abnormality determining means 63 indicates that the position of the gauze frame 21 is abnormal. Determined to have occurred.

The plate-making control means 64 moves the head portion 30 and the platen portion 40 from the other end side of the gauze frame 21 to one side with the pressing force adjusting means 50 pressing the heat sensitive mesh 22 with the platen roller 42 and the thermal head 32. The thermal head 32 is controlled so as to heat and perforate while moving it toward the end portion side, that is, in the X2 direction.

FIG. 5 is a schematic diagram schematically explaining the operation of the thermal plate making apparatus 10 according to the present embodiment of the present invention. (A) is a diagram showing a state in which the head unit 30 and the platen unit 40 are moved in the X1 direction, and (b) is a diagram showing a state in which the head unit 30 and the platen unit 40 are stopped. FIG. 7C is a diagram showing a state in which the head unit 30 and the platen unit 40 move while heating and punching in the X2 direction. The head unit 30 and the platen unit 40 are referred to as a plate making unit 70.

As shown in FIG. 5A, the pressing member/positioning member 34 also has a function as a reference position fixing member, and the front end portion 21a of the gauze frame 21 is fixed so that the gauze frame 21 does not shift in the X2 direction. Pressed.

Then, the plate making unit 70 is moved in the X1 direction with the platen roller 42 of the platen section 40 in the release position. As a result, the platen roller 42 and the thermal head 32 are moved in the X1 direction without being pressed, so that the gauze frame 21 does not shift in the X1 direction even during the movement.

While the plate making unit 70 is moving in the X1 direction, the sensor 35 detects whether or not it has come into contact with the inner frame 21c of the rear end portion of the gauze frame 21.

Then, as shown in FIG. 5B, the plate making control means 64 moves the plate making unit 70 in the X1 direction by the movement amount L1 calculated by the calculating means 62, and stops the movement at the point where the movement amount L1 is reached. Let

When the sensor 35 detects the inner frame 21c at the rear end of the mesh frame 21 during the movement in the X1 direction, the malfunction determining unit 63 determines that an abnormality has occurred at the position of the mesh frame 21.

When the plate making unit 70 is moved in the X1 direction by the movement amount L1 without being judged as abnormal by the abnormality judging means 63, the plate making control means 64 causes the pressing force adjusting means 50 to press the platen roller 42 of the platen portion 40 to the pressing position. Move to.

Then, the plate making control unit 64 controls the platen roller 42 and the thermal head 32 so as to heat and perforate the plate making unit 70 while moving the plate making unit 70 in the X2 direction while pressing the thermal sensitive cloth 22.

A cleaning brush 36 as a cleaning means is provided on the head 30 side of the heat sensitive cloth 22 so as to come into contact with the heat sensitive cloth 22. The cleaning brush 36 is provided in the X1 direction (on the side of the pressing member/positioning member 34) of the head portion 30. As a result, the cleaning brush 36 can remove dust and dirt adhering to the surface of the heat-sensitive cloth 22 while the head unit 30 is moving in the X2 direction.

Although an example in which the cleaning brush 36 is provided as the cleaning unit is shown, the cleaning unit is not limited to this, and the cleaning unit may be an air blowing unit that removes dust or dirt by blowing air onto the surface of the heat sensitive gauze 22, or a heat sensitive unit. An adhesive roller that removes dust and dirt by bringing an adhesive surface into contact with the surface of the gauze 22, and an air suction means that removes air by sucking air together with the dust and dirt on the surface of the heat-sensitive gauze 22. May be.

FIG. 6 is a flowchart illustrating the operation of the thermal plate making apparatus 10 according to the present embodiment of the present invention.

As shown in FIG. 6, when a plate making start is requested from a PC (not shown) or the like (step S101; YES), the plate making unit 70 is moved in the X1 direction with the platen roller 42 in the release position (step S103). ..

While the plate making unit 70 is moving in the X1 direction, it is determined whether or not the sensor 35 is turned on, that is, whether the sensor 35 has come into contact with the inner frame 21c of the gauze frame 21 (step S105).

When the sensor 35 is in the off state (step S105; YES), if the plate making unit 70 is moved in the X1 direction by the movement amount L1 (step S109; YES), it is presumed that the plate making unit 70 could be moved to an appropriate position based on the job. Therefore, the plate-making control means 64 causes the pressing force adjusting means 50 to press the platen roller 42 (step S111).

Then, the plate-making control unit 64 moves the plate-making unit 70 in the X2 direction until the reference position is reached while pressing the heat sensitive mesh 22 with the platen roller 42 and the thermal head 32, and the image data included in the job. Based on the above, the thermal head 32 controls to heat and punch (step S113).

When the plate making unit 70 reaches the reference position (step S115; YES), the plate making control means 64 stops the plate making operation (step S117).

On the other hand, before the plate making unit 70 is moved in the X1 direction by the movement amount L1 (step S109; NO), the sensor 35 is turned on, that is, when the inner frame 21c at the rear end of the gauze frame 21 is detected (step S105). NO), it can be inferred that the plate making unit 70 cannot be stopped at an appropriate position based on the job, and therefore the abnormality determination means 63 causes the display unit 80 to display an error message (step S107).

In this way, when the sensor 35 detects the inner frame 21c at the rear end of the gauze frame 21 during the movement of the plate making unit 70 in the X1 direction in which heating and punching is not performed, the gauze frame 21 is detected. Since it is determined that an abnormality has occurred at the position of No. 2, it is possible to reset the gauze frame 21 even when the plate making unit 70 cannot be stopped at an appropriate position based on the job.

In the present embodiment of the present invention, the plate making unit 70 is controlled to be heated and perforated by the thermal head 32 while moving in the X2 direction, but the movement is not limited to the plate making unit 70, and the gauze frame 21 may be moved. You may That is, one of the gauze frame 21 and the plate making unit 70 may be moved relatively.
