A fabric roller 90 for winding the fabric is provided.

  Further, the image forming apparatus 1 includes an apparatus main body 5 provided with a fabric supply roller 10 and a binder coating apparatus 20 inside, and a stand 6 that supports the apparatus main body 5. In this example, the print head 30 includes an inkjet nozzle 31 driven by a piezo element, and applies a sublimable ink of a predetermined color to the fabric 2. The fabric 2 that moves under the print head 30 is driven to move intermittently in the direction of arrow A in accordance with the sublimation ink discharge timing of the print head 30.

  The pre-heater 40 includes a far-infrared lamp 41 and heats and dries the fabric 2 coated with sublimable ink. The tension adjusting device 50 is provided with a tension adjusting knob 52 in addition to the spring 51, and adjusts to a predetermined tension.

  In addition, a heater 61 is disposed around the heating drum 60, and the fabric 2 is heated to a predetermined temperature to develop sublimation ink and dye the fabric. In this case, the heating temperature of the heating drum 60 can be selected depending on the type of fabric. For example, 170 to 180 ° C for polyester and 150 to 160 ° C for nylon are suitable. In the figure, reference numeral 62 denotes a duct for ventilation in the apparatus.

  In this example, the cutter device 80 includes a blade 81 heated by an electric heater and a roller 82 that sandwiches the fabric 2 between the blade 81 and melts and cuts the fabric 2. If the movement of the fabric 2 is intermittent at this time, the fabric 2 may be burnt by overheating when the fabric 2 is stationary. Therefore, an automatic tension bar 70 is provided so that the intermittent movement of the fabric 2 is continuously moved. I have to. In this cutter device 80, a range printed on the fabric 2 is detected by a sensor 83, and the blade 81 is moved to the width.

  In this example, a predetermined pattern or the like is printed on the fabric 2, and the fabric roller 90 is wound up in a state of being cut to a predetermined width.

  According to this example, according to the image forming apparatus for a fabric according to the embodiment, the application pattern is formed by directly applying the sublimation ink to the fabric without using the transfer paper. Distortion of the coating pattern due to the difference can be prevented. In addition, since an anti-bleeding agent for the fabric is applied to the fabric before applying the sublimable ink, it is possible to prevent the fabric from bleeding when the sublimable ink is applied. Further, since the sublimable ink is dried before heating, the sublimable ink can be dried before heating, and the fabric can be efficiently dyed by heating.

  Furthermore, since the sublimation ink is applied to the fabric with an inkjet nozzle, an appropriate amount of ink can be precisely applied. Moreover, since heating is performed with a heating drum, the fabric coated with the sublimable ink can be efficiently and uniformly heated. And since the movement adjustment which changes the intermittent movement of the cloth to the continuous movement is performed between the ink application and the heating, even if the cloth is sent intermittently during the ink application, the cloth is continuously applied during the drying. It can be sent, and there will be no trouble in continuous heating.

  In the above example, the binder coating device is provided. However, when using a fabric coated with the binder or a fabric that does not cause bleeding, it is not necessary to provide the binder coating device in the image forming apparatus for the fabric. Moreover, although the example which applies sublimation ink with an inkjet nozzle was shown, what kind of means may be used for application | coating of this ink. Further, a drying device for drying the sublimable ink before heating is not always necessary, and the heating device is not limited to the heating drum, and any type of heating device can be used.

  Next, another embodiment of the present invention will be described. FIG. 4 is a conceptual diagram of an image forming apparatus for cloth according to another embodiment. In this example, a sag detector 410 that detects the sagging of the fabric as a fabric transfer state of the fabric 2 is disposed downstream of the roller 21 of the image forming apparatus 1, and the rotational speeds of the roller 21 and the tension adjusting device 50 are determined according to the fabric speed. Control is performed by the rotation synchronization means 400 which is a transfer speed control means. That is, when the rotation synchronization means 400 detects the sag of the fabric 2, the rotation of the roller 21 and the tension adjusting device 50 is adjusted so that the fabric 2 does not sag. Here, an ultrasonic sensor, an optical sensor, or the like can be used as the slack plugging device 410. These sensors generate a slack state of the fabric 2 in the plugging device 410 installation region. This is done by inputting the reflection state.

  Further, in the present invention, the heating device is disposed in a region where the fabric moves and is non-contact heating means for heating the fabric in a non-contact manner, and the fabric contact heating unit disposed in the region and contacting the fabric to heat the fabric.

The cylindrical member 430 is attached to the non-contact heating member 421. Therefore, the heating apparatus according to this example can be realized by simply attaching the cylindrical member 430 to the heating drum 60 of the image forming apparatus 1 described above.

  According to this example, as shown in FIG. 5, the fabric 2 comes into contact with the cylindrical member 430 before and after the cylindrical member 430 without contacting the non-contact heating member 421. The fabric 2 then moves downstream without contacting the non-contact heating member 421. In this example, if the heater incorporating the non-contact heating member 421 is heated to, for example, about 150 degrees Celsius, the cylindrical member 430 is also heated to the same temperature, and the fabric 2 is non-contacting upstream of the cylindrical member 430. Heating is performed in a non-contact state by the environmental temperature and radiation increased by the heating member 421, and then heated directly by contacting the cylindrical member 430. Even after leaving the cylindrical member 430, the non-contact heating member 421 is heated in a non-contact manner.

  Therefore, according to this example, the cloth coated with the sublimable ink is preheated in a non-contact manner by the non-contact heating member 421 and then directly heated by the cylindrical member 430. Therefore, the ink sublimation is effectively performed. In addition, since the time and distance of contact with the cylindrical member 430 are short, color mixing of ink due to contact can be prevented.

According to this example, similarly to the above-described example, color mixing due to the contact of the protruding portion 442 that is a non-contact heating unit with the fabric 2 can be prevented, and the non-contact heating member 441 and the protruding portion 442 are provided. There is no fear of coming off. Note that the protruding portion 442 is not limited to one row, and a plurality of rows can be provided.

  FIG. 8 is a cross-sectional view showing a configuration of a heating device according to another embodiment. In this example, the heating device 450 has a cylindrical wall-shaped non-contact heating member 451 provided with a row of protrusions 452, and the protrusions 452 are covered with a cover member 460. The cover member 460 is made of a ceramic material, and has a main body 461 having a smooth contour and a groove portion 462 for attachment to the ridge 452. According to this example, it is possible to suppress the wear of the contact heating unit and reduce the resistance to the fabric 2, and also to replace the cover member 460 and to make the heating device 450 have a long life.
