(First embodiment)
The hot press apparatus according to the embodiment of the present invention is used for performing sublimation transfer. In addition, a hot press apparatus is applicable also to the other apparatus which requires the process of performing pressurization and heating (henceforth a hot press) with respect to a target object.

  A sublimation transfer apparatus 10 shown in FIG. 1 includes a heating unit 20, a support base 30, a control unit 40, and a sensor unit 42. In the present embodiment, the fabric 50 and the sublimation transfer sheet 60 are the targets of the hot press by the sublimation transfer apparatus 10. The fabric 50 according to the present embodiment is made of a resin fiber material such as polyester, but clothing and fasteners made of a resin fiber material such as polyester can also be used.

  The heating unit 20 is configured to be movable up and down, and includes a plurality of coil units 22 and a conductor plate 24 in which a conductor is formed in a plate shape. Each of the plurality of coil portions 22 has a coil 23, and a current flows through each coil portion 22 when a current is supplied from a power source (not shown). The conductor plate 24 is made of a magnetic material and generates heat due to electromagnetic induction of the coil portion 22. The conductor plate 24 preferably has a high thermal conductivity in order to efficiently transmit the generated heat to the fabric 50 and the sublimation transfer sheet 60.

  The support base 30 is provided to face the heating unit 20. The fabric 50 and the sublimation transfer sheet 60 placed on the fabric are set on the support table 30. In the present embodiment, the conductive plate 24 that generates heat is pressed against the fabric 50 and the sublimation transfer sheet 60 to be subjected to hot pressing, whereby heat and pressure are applied to both, and the sublimation transfer sheet 60 is heated. The design is transferred to the fabric 50 by sublimation.

  The control unit 40 is for controlling a current supplied to the coil unit 22 from a power source (not shown). Specifically, the presence / absence of current supply, supply amount, supply time, and the like can be controlled independently for each coil unit 22. For example, all the coil portions 22 may be used to simultaneously generate heat in all the regions of the conductor plate 24, or only a specific region of the conductor plate 24 may be heated using some of the coil portions 22.

  Furthermore, it is possible to move the heat generating region of the conductor plate 24 by sequentially switching the coil portions 22 to which current is supplied. According to such a configuration, it is not necessary to move the coil portion 22 itself in order to move the heat generation region, and therefore it is possible to reduce the number of movable portions that can cause a failure.

  The sensor unit 42 is for measuring the temperature distribution of the object (the fabric 50 and the sublimation transfer sheet 60). The sensor unit 42 includes a plurality of sensor elements 46. Each sensor element 46 is provided close to the conductor plate 24 and measures the heating temperature of the object by measuring the temperature of the conductor plate 24. The sensor unit 42 measures the temperature distribution of the conductor plate 24 based on the temperature measured by the sensor element 46. The measured temperature distribution is sent to the control unit 40 as information on the temperature distribution. The control unit 40 can control the current supplied to each coil unit 22 based on the information. Note that the temperature distribution state measurement by the sensor unit 42 may always be performed, and information regarding the temperature distribution may be continuously sent to the control unit 40. Thus, the conductor plate 24 can always generate heat at the same temperature. For example, even when a plurality of fabrics 50 are processed, all the fabrics can be heated under the same conditions, and the same quality can be obtained. Can keep.

  In addition, as a method for measuring the temperature distribution, the sensor unit 42 and the thermography may be linked to directly measure the temperature distribution of the conductor 24 or the object to be hot pressed.

  If necessary, the sublimation transfer apparatus 10 according to the present embodiment may further include a steam unit that sprays water vapor or the like on the fabric 50 during the sublimation transfer operation or after the sublimation transfer operation.

  As described above, according to the present embodiment, since the conductor plate 24 itself generates heat by electromagnetic induction of the coil portion 22, the temperature of the conductor plate 24 can be instantaneously increased. Therefore, the first sublimation transfer operation can be started immediately even after the power of the sublimation transfer apparatus 10 is turned on. Moreover, since it becomes possible to heat quickly when heating is needed, it is not necessary to always heat the conductor board 24. FIG. Therefore, work efficiency can be improved and economic costs such as electricity bills can be reduced.

  Although the sublimation transfer apparatus 10 according to the above-described embodiment performs sublimation transfer on one side of the fabric 50, a heating unit 20 ′ as shown in FIG. Sublimation transfer may be performed on both sides of 50.
