  As shown in FIGS. 1 to 7, the thermal transfer machine 10 according to the present embodiment uses a clothing material 60 (shown in FIG. 7) as an object to be transferred, and a transfer sheet 50 (shown in FIG. 6). ) Is a device for printing a transfer mark 51 (shown in FIG. 6) such as a logo by thermal transfer.

  As shown in FIG. 1, the thermal transfer machine 10 includes a work table 13 that performs a heat transfer operation on a base plate 12 supported by a plurality of legs 11, and a hole 18 provided in the work table 13. The lower transfer mold 30 is arranged so that it does not move just inside. Moreover, the support | pillar 14 is each provided in the both ends of the base 12 of the thermal transfer machine 10, and the supporting member 15 which connects this support | pillar 14 is arrange | positioned. In the support member 15, the pressurizing device 16 and the upper transfer die 20 attached to the lower end portion thereof are supported at a position directly above the lower transfer die 30. The pressurizing device 16 can move the upper transfer mold 20 up and down, and comes into contact with the lower transfer mold 30 disposed directly below and is at a predetermined pressure (1 atm in the embodiment of the present invention). (101325 Pa)). A power supply device 17 is provided below the base 12 for operating the pressurizing device 16 and heating the upper transfer die 20 and the lower transfer die 30 as will be described later. Further, the support member 15 is provided with an operation switch 19 for controlling the start and stop of the pressurizing device 16 and the heating start and stop of the upper transfer mold 20 and the lower transfer mold 30 in conjunction with each other. .

  Next, the upper transfer mold 20 and the lower transfer mold 30 will be described in detail.

  The upper transfer mold 20 is a pressurizing unit that applies pressure to the transfer sheet 50 and the cloth 60 from above. As shown in FIG. 3A, the upper transfer mold 20 is a substantially rectangular parallelepiped mold, and includes a transfer mark 51 that performs thermal transfer. An upper pressurizing portion 21 having the same shape as the outer shape is formed to project, and as shown in FIG. 4 and the like, the upper pressurizing portion 21 faces downward, It is attached by bolting. The upper transfer mold 20 according to the embodiment of the present invention is a pressure heating unit that applies pressure to the transfer sheet 50 and the cloth 60 and heats the transfer sheet 50 and the cloth 60, and generates heat inside the mold. A device (not shown) is provided. The heat generating device is supplied with power from the power supply device 17, and the heat generating device is operated by pressing the operation switch 19. In the embodiment of the present invention, the upper transfer mold 20 is heated to 160 ° C. by the heat generating device.

  The lower transfer mold 30 is a pressurizing unit that applies pressure to the transfer sheet 50 and the cloth 60 from below. As shown in FIG. 3B, the lower transfer mold 30 is a substantially rectangular parallelepiped mold. A lower pressurization unit 31 formed to face the upper pressurization unit 21 is provided. Similarly to the upper pressurizing unit 21, the lower pressurizing unit 31 is formed so as to have the same shape as the outer shape of the transfer mark 51, and protrudes above the lower transfer mold 30. Further, as described above, the lower transfer mold 30 is stored in the hole 18 formed in the work table 13 of the base plate 12 so as not to move, and receives the pressure of the upper transfer mold 20 for transfer. The transfer mark 51 and the fabric 60 of the sheet 50 are sandwiched.

  And this lower pressurization part 31 and above-mentioned upper pressurization part 21 are constituted so that it may become just the same external shape, if it makes it contact. Here, in the upper transfer mold 20 and the lower transfer mold 30 according to the embodiment of the present invention, only the upper pressurizing unit 21 and the lower pressurizing unit 31 that are formed to project are in contact with each other via the transfer sheet 50 and the cloth 60. Thus, pressure is applied to the transfer mark 51 and the fabric 60 of the transfer sheet 50, and the other parts of the upper transfer mold 20 and the lower transfer mold 30 are connected to the upper pressurizing unit 21. Even if the lower pressurizing unit 31 is in contact with the transfer sheet 50 and the cloth 60, the height is set so as not to contact both. For this reason, pressure is not applied to surrounding portions other than the transfer mark 51 portion to be thermally transferred on the transfer sheet 50 or the cloth 60. As a result, when thermal transfer is performed, it is possible to prevent thermal transfer marks from being generated on the surrounding fabric 60.

  Further, the lower transfer mold 30 according to the embodiment of the present invention has a transfer sheet restricting portion 32 that restricts the arrangement position of the transfer sheet 50 around the lower pressurizing portion 31. The transfer sheet restricting portion 32 according to the embodiment of the present invention has a substantially rectangular frame shape surrounding the lower pressurizing portion 31 and is formed to have a predetermined height higher than the lower pressurizing portion 31. ing. The transfer sheet restricting section 32 fits the transfer sheet 50 having the same size and the transfer mark 51 at the same position so that the transfer mark 51 faces upward. It is comprised so that it may become the same shape as the pressurization part 31, and may be arrange | positioned in the position which overlaps.

  In the embodiment of the present invention, the height of the lower transfer mold 30 and the hole 18 is set so that the height of the transfer sheet regulating portion 32 in the lower transfer mold 30 is flush with the height of the work table 13. It has been decided. Further, the corners 33 at the four corners of the transfer sheet restricting portion 32 are rounded, thereby damaging the arranged transfer sheet 50 and the cloth 60 as compared with the case where the corners are sharp. The possibility that it will fall is made low.

  The height of the transfer sheet restricting portion 32 is formed to be a predetermined amount higher than the height of the lower pressurizing portion 31 because the transfer auxiliary member 40 described later is disposed on the lower pressurizing portion 31 and This is because when the transfer sheet 50 is arranged on the top, the height of the transfer sheet 50 is exactly the same as the height of the transfer sheet regulating portion 32. By setting the heights of the lower pressurizing unit 31 and the transfer sheet regulating unit 32 in consideration of the arrangement of the transfer assisting member 40 in this way, the transfer sheet regulating unit 32 can ensure the transfer sheet 50. In addition, the arrangement position can be regulated, and an effect (described later) by using the transfer auxiliary member 40 can also be obtained.

  Here, if the height of the transfer sheet restricting portion 32 is set to be the same as the height of the lower pressurizing portion 31, for example, without considering the arrangement of the transfer assisting member 40, the transfer assisting member 40 is added downward. Since the transfer sheet 50 is disposed at a position higher than the height of the transfer sheet restricting portion 32 when the transfer sheet 50 is disposed thereon after being disposed on the pressure portion 31, the position of the transfer sheet 50 is disposed. Therefore, the transfer sheet restricting section 32 cannot control the transfer sheet restricting section 32, and the transfer sheet restricting section 32 does not play its role.

  Further, in the embodiment of the present invention, in addition to the upper transfer mold 20, the lower transfer mold 30 also serves as a pressure heating unit that applies pressure to the transfer sheet 50 and the cloth 60 and heats the transfer sheet 50 and the cloth 60. The lower transfer mold 30 is also provided with a heat generating device (not shown) inside the mold. This heating device is also supplied with power from the power supply device 17, and when the operation switch 19 is pressed, heat generation is started simultaneously with the heating device of the upper transfer mold 20. In the embodiment of the present invention, the lower transfer mold 30 is heated to 70 to 80 ° C. by the heat generating device.

  As described above, in addition to the upper transfer mold 20, the lower transfer mold 30 is also a pressure heating unit, so that the transfer sheet 50 and the fabric 60 are heated more uniformly with only the upper transfer mold 20. In addition, the transfer sheet 50 and the fabric 60 can be heated, and problems such as the transfer mark 51 being peeled off due to poor adhesion after thermal transfer can be prevented. Furthermore, since the heating temperature of the upper transfer mold 20 and the lower transfer mold 30 are set so that the heating temperature of the upper transfer mold is 160 ° C. and the heating temperature of the lower transfer mold 30 is 70 to 80 ° C. Necessary heat can be transferred to the transfer sheet at an optimum temperature, and heat transfer of the transfer mark to the transfer object can be performed reliably and efficiently.

  Next, a thermal transfer method using the thermal transfer machine 10 according to the embodiment of the present invention will be described with reference to FIGS.

  First, as shown in FIGS. 1, 2, and 4, the lower transfer mold 30 is placed and fixed in the hole 18 so that the lower pressurizing portion 31 faces upward, and the upper transfer mold 20 is fixed by the upper pressurizing portion 21. Attach to the pressure device 16 with bolts or the like so that it faces downward.

  Next, as illustrated in FIG. 5, the transfer assisting member 40 is disposed so as to overlap the lower pressure unit 31. The transfer assisting member 40 is made of a material such as plastic (for example, urethane) having heat resistance and elastic force (repulsive force), and includes an upper pressure unit 21 and a lower pressure unit 31. And a member having a predetermined thickness formed in the same shape as the outer shape of the transfer mark 51. By sandwiching the transfer auxiliary member 40 between the lower pressurizing portion 31 and the transfer sheet 50, the transfer mark 51 is easily brought into close contact with the cloth 60 due to its elastic force (repulsive force). Thermal transfer can be performed. Further, the transfer assisting member 40 is sandwiched between the upper pressurizing part 21 of the upper transfer mold 20 and the lower pressurizing part 31 of the lower transfer mold 30, thereby moving the upper transfer mold 20 downward and applying the upper pressure. The effect of alleviating both impacts when the part 21 and the lower pressurizing part 31 are brought into contact with each other via the transfer sheet 50 and the cloth 60 can also be obtained.

  Next, as shown in FIG. 6, the transfer sheet 50 formed in advance in the size and shape of the frame of the transfer sheet restricting portion 32 is transferred to the transfer sheet restricting portion 32 so that the transfer mark 51 faces upward. Along the lower transfer mold 30. Then, the transfer sheet 50 is regulated by the transfer sheet regulating unit 32, and the outer shape of the transfer mark 51 is exactly the same as that of the lower pressurizing unit 31, and is arranged at a position overlapping the upper side. Further, by calculating so that the height of the transfer sheet regulating portion 32 and the combined height of the transfer auxiliary member 40 and the transfer sheet 50 are exactly the same, the transfer sheet 50 can be transferred with the transfer sheet 50 disposed. The sheet 50 and the transfer sheet regulating portion 32 are configured to be flush with each other.

  Next, a material 60 as a material to be transferred is placed on the transfer sheet 50, and the operation switch 19 is pressed to operate the pressure device 16, the heat generating device of the upper transfer mold 20, and the heat generating device of the lower transfer mold 30. Then, as shown in FIG. 7, the upper transfer mold 20 is pushed downward by the pressure device 16, and the upper transfer mold 20 and the lower transfer mold 30 (in the embodiment of the present invention, the transfer auxiliary member 40) are used. While sandwiching the transfer sheet 50 and the cloth 60, the upper transfer mold 20 and the lower transfer mold 30 are heated at a predetermined temperature. Accordingly, the transfer sheet 50 and the cloth 60 are sandwiched between the heated upper transfer mold 20 and the heated lower transfer mold 30, the adhesive of the transfer mark 51 is melted, and the transfer mark 51 is moved to the cloth. 60. In the embodiment of the present invention, the heating temperature of the upper transfer mold 20 is 160 ° C., the heating temperature of the lower transfer mold 30 is 70 to 80 ° C., the pressure applied by the pressure device 16 is 1 atm (101325 Pa), and the processing time. Performed the transfer operation in 10 seconds.

  Thereafter, the upper transfer mold 20 is moved upward, the heating devices of the upper transfer mold 20 and the lower transfer mold 30 are stopped, the transfer sheet 50 and the fabric 60 are taken out from the thermal transfer machine 10, and the transfer sheet 50 and the fabric 60 are removed. After natural cooling, the transfer sheet 50 is peeled off leaving the transfer mark 51 from the fabric 60, and the thermal transfer process is completed.

  As described above, according to the thermal transfer machine 10 of the embodiment of the present invention, the thermal transfer machine 10 includes the upper transfer mold 20 in which the upper pressurizing portion 21 having the same shape as the outer shape of the transfer mark 51 protrudes downward, and the upper transfer mold 20. The transfer mold 20 has a lower transfer mold 30 opposite to the upper pressurizing section 21 of the transfer mold 51 and having a lower pressurizing section 31 of the same shape as the transfer mark 51 projecting upward. ) 60 and the transfer mark 51 of the transfer sheet 50 are sandwiched and heated, so that the fabric (transferred material) 60 around the thermally transferred mark 51 is reliably generated without generating a thermal transfer mark. The transfer mark 51 of the transfer sheet 50 can be thermally transferred to the object 60).
