Through such a structure, the upper heating plate 30, the lower heating plate 40, and the side edge bars 50a and 50b do not directly press the transfer film 7 of the door 5, but the buffer member rich in elastic force. (70a) 70b (70c), for example, pressurized through the buffer member (70a) 70b (70c) made of cloth or the like. In addition, such buffer members 70a, 70b, 70c are locally distributed by uniformly distributing heat transferred from the upper heating plate 30, the lower heating plate 40, and the side edge bars 50a, 50b. It also functions to heat the door 5 and the transfer film 7 uniformly as a whole without temperature variation due to phosphorus overheating.

Meanwhile, as shown in FIGS. 4 and 6, the door 5 is formed with a portion of the flange 5a on which one side thereof protrudes to the upper side. Such a flange 5a portion has a lower side and a lower portion. Sides of the doors 5 adjacent thereto are supported in a "a" shape by one side corner bar 50a, and an upper side of the flange 5a is inserted into a recess 30a formed in the upper heating plate 30 to be hot pressed. do. Therefore, the entire surface of the door 5 is in contact with the transfer film 7 to receive a pattern from the transfer film 7.

The pressurized thermal transfer apparatus 1 according to the present invention configured as described above moves the trolley 22 to the front side of the main body 10 so that the door 5 covered with the transfer film 7 is placed on the back. The trolley 22 has a transfer position in which the lower heating plate 40 is located directly below the upper heating plate 30, and is movable from the transfer position to the detachable position in front of the frame, and the lower heating plate (in the detachable position). The door 5 and the transfer film 7 are raised on the 40, or the door 5 and the transfer film 7 which have been transferred are lowered.

1 and 2 show the lower heating plate 40 in the detached position, and FIG. 4 shows the lower heating plate 40 in the transfer position.

When the door 5 and the transfer film 7 are placed on the lower heating plate 40 in this way, as shown in FIG. 4, the lower heating plate 40 and the left and right corner bars 50a and 50b are shown. The doors 5 and the transfer film 7 are placed on the buffer members 70b and 70c, respectively. When the push cylinder 56 is operated, as shown in FIG. 6, the door 5 and the transfer film 7 are placed between the lower heating plate 40 and the left and right corner bars 50a and 50b. The left and right sides are supported. In such a state, the upper buffer member 70a is extended again on the upper part of the door 5 and the transfer film 7, and a motor (not shown) of the transfer part 20 is operated to move the cart 22 to the main body part ( 10), and in this case, when the motor moves the chain 24 through the sprocket (not shown), the trolley 22 connected to the chain 24 is led, and the trolley ( The wheels 22a mounted on the lower surface of 22 move on the rail 12 and move from the detached position to the transfer position.

Then, after moving to the transfer position as described above, the hydraulic cylinders 62 of the lifting unit 60 as shown in FIG. 3 are operated, and the four hydraulic cylinders 62 are each of the lower heating plate 40. The lower side is supported on all sides and lifted up, and the lower heating plate 40 is lifted up from the trolley 22 while being lifted up to the upper heating plate 30 side, and the door 5 and the transfer film 7 and the upper side buffer are lifted up. The member 70a is crimped | bonded between the upper and lower heating plates 30 and 40. In this case, the upper heating plate 30 naturally absorbs the lifting force of the hydraulic cylinder 62 because the rod 34 is elastically supported downward by the spring 36, and as a result, the door 5 and The transfer film 7 has the upper and lower heating plates 30 and 40 and the left and right corner bars 50a and 50b surrounded by a plurality of buffer members 70a, 70b and 70c on the outer surface thereof. Is pressed by.

In this case, the upper and lower surfaces of the door 5 and the transfer film 7 are pressed by the lifting force of the hydraulic cylinder 62 and the elastic force of the spring 36, and the left and right sides are opposite to the push cylinder 56 and the opposite side. Is pressed by the stopper 54. In this state, power is supplied to the upper and lower heating plates 30 and 40, and is directly heated by the electric heating heaters 32 and 42, and the left and right corner bars 50a and 50b are lower heating plates ( It is heated by heat transmitted from 40 to heat both sides of the door 5 and the transfer film 7.

After 5 minutes have elapsed through the heating operation, the pattern is thermally transferred from the transfer film 7 to the door 5. When the heat transfer is completed, the hydraulic cylinder 62 of the lifting unit 60 is lowered, and the trolley 22 is moved from the transfer position to the detachable position to move the door 5 and the transfer film 7 to the lower heating plate ( After lowering from 40, the transfer film 7 is removed from the surface of the door 5 to produce a door 5 on which the pattern is transferred.

As described above, according to the present invention, the transfer film 7 is disposed on the surface of the door 5, and the transfer film 7 is disposed between the upper heating plate 30 and the lower heating plate 40 and the left right corner bars 50a and 50b. High-quality transfer pattern by direct heating method by direct heating method by transferring the pattern formed in the film 7 to the surface of the door 5 by heat pressing in the state surrounded by the buffer members 70a, 70b and 70c. The door 5 can be produced.

In the present invention, the door 5 is mounted on the lower heating plate 40 at the front side of the main body 10, and the inner side of the main body 10 is driven by a chain 24 driving method using a motor (not shown). After moving to the upper surface of the door 5 and the left and right corners of the door 5 by the electric cylinder 60 of the elevating section 60, the electric cylinder is raised to the upper heating plate 30 side by itself, Transcription work can be achieved over. Therefore, compared with the conventional vacuum crimping method, an excellent effect that can achieve a significant improvement in the work efficiency is obtained.
