However, the conventional method requires a certain amount of space for peeling the base film from the transfer medium, and therefore it is difficult to peel the base film in the small transfer device. there were. Further, since the peeling process takes a long time, it hinders the process of feeding the next transfer material and the process of painting, which is very inefficient. Further, when the base film is wound after the transfer, since the base film deformed into irregularities is wound around the winding roller 16, the volume of the transfer material becomes 10 times or more that of the roll of the transfer material before being sent out. Therefore, it is necessary to provide a wide space for the take-up roll or to frequently replace the take-up roll.

Therefore, the present invention solves the above problems and provides a transfer method in which the steps of feeding and painting the transfer material proceed rapidly and are efficient, and the roll space of the wound base film is small. The purpose is to provide.

First, a transfer device used in the transfer method of the present invention will be described.

The mounting table 1 is provided with a sealing wall 12 higher than the transferred body 3 around the upper surface thereof. A large number of suction holes 13 are formed on the upper surface on which the transferred body 3 and the bottom raising plate 2 are placed. The suction hole 13 is connected to the suction member 14, and the transfer target 3
The gas between the transfer material 8 and the bottom raising plate 2 is sucked.

The bottom raising plate 2 is laid on the mounting table 1, on which the transferred material 3 is mounted, and the flexible sheet 9 is placed on the transferred material 3.
When it is pressed against, the transfer material 8 is deformed to a height higher than the height of the transferred body 3. The upper surface of the bottom raising plate 2 is set within the lower surface of the transferred body 3. When the upper surface of the bottom raising plate 2 protrudes from the lower surface of the transferred body 3, it becomes difficult for the transfer material 8 to adhere to the periphery of the upper surface of the transferred body 3.

The frame body 4 surrounds the transferred body 3 and forms a groove 5 between the frame body 4 and the transferred body 3. Transfer material 8 by groove 5
The portion where the break occurs is guided around the transferred body 3.

The transfer material 8 is a roll formed by laminating a transfer layer such as a release layer, a pattern layer and an adhesive layer on the base film 6 and winding it. After the transfer to the transfer target 3, the base film 6 is peeled off to form a transfer layer on the surface of the transfer target 3. The transfer layer may include a metal vapor deposition layer.

A feed roller 15 and a take-up roller 16 are arranged on both sides of the area where the mounting table 1 and the support member 10 face each other. The roll-shaped transfer material 8 is sent from the sending roller 15 toward the take-up roller 16, and when the transfer layer is transferred to the transfer target 3, a new transfer layer is sent from the sending roller 15 by a predetermined pitch. The base film 6 from which the transferred portion of the layer has been cut and removed is wound by the winding roller 16. The transfer material 8 is not limited to a roll-shaped material, and may be a sheet-shaped sheet and replaced every time transfer is performed once.

The flexible sheet 9 has, for example, a thickness of 1 to 3.
Any material that can be elastically deformed along the three-dimensional shape of the transferred body 3 and has heat resistance, such as a silicon rubber of about mm, may be used.

The support member 10 is a box-shaped main body 3 to be transferred.
The plate-shaped heating member 17 and the flexible sheet 9 are provided on the surface facing the
Have. The heating member 17 has a large number of fine holes formed as fluid inlet / outlet holes 18 on its surface. Further, if the surface of the heating member 17 is roughened to have an uneven surface, the flexible sheet 9 can be easily suction-adhered. A heat source 19 is embedded between the fine holes so that the heat source 19 heats the entire heating member 17. As the heat source 19, an electric heater, steam,
A heat transfer oil can be applied. Flexible sheet 9 and support member 1
A fluid supply member 20 for supplying the fluid 11 through the supply passage 21 and a fluid discharge member 22 for discharging the supplied fluid 11 through the discharge passage 23 are provided between the two. As the fluid 11, for example, a liquid such as water or oil,
A gas such as steam or compressed air is used. Also, fluid 1
If 1 is heated in advance, the heating efficiency will be improved.
When the fluid 11 is supplied from the fluid supply member 20, the fluid 11 is ejected from the fluid inlet / outlet hole 18 of the heating member 17, the space between the flexible sheet 9 and the heating member 17 is expanded, and the flexible sheet is formed. 9 is in a pressurized state. On the other hand, when the flexible sheet 9 is heated, the fluid 11 between the flexible sheet 9 and the heating member 17 is discharged from the fluid inlet / outlet hole 18 of the heating member 17 by the fluid discharge member 22, and the flexible sheet 9 is discharged. 9 is attracted to and brought into contact with the heating member 17, and the flexible sheet 9 is heated by heat conduction.

The support member 10 can be moved up and down with respect to the transferred body 3 on the mounting table 1 by a driving member (not shown).

According to the transfer apparatus as described above, as shown in FIG. 1, the bottom raising plate 2 is laid on the mounting table 1 and the transferred body 3 is mounted thereon, and the periphery of the transferred body 3 is placed. A groove 5 is formed between the frame body 4 and the transferred body 3 while being surrounded by the frame body 4, and the transfer layer of the transfer material 8 is opposed to the transferred body 3. At this time, the flexible sheet 9 discharges the fluid 11 from the fluid discharge member 22 so that almost the entire surface of the flexible sheet 9 is adsorbed on the surface of the heating member 17, and the flexible sheet 9 is flexible by the heat source 19 of the heating member 17. The sheet 9 is directly heated by heat conduction.

Next, as shown in FIG. 2, the support member 10 is lowered and pressed against the wall 12 of the mounting table 1 via the flexible sheet 9 and the transfer material 8. Further, the fluid 11 is ejected from the fluid supply member 20 through the fluid inlet / outlet hole 18 of the heating member 17 to expand the space between the heating member 17 and the flexible sheet 9 to pressurize the flexible sheet 9. . The transfer material 8 together with the flexible sheet 9 is pressed against the upper surface of the transferred body 3 so that the flexible sheet 9 and the transfer material 8 follow the three-dimensional shape of the transferred body 3. The transfer layer of the transfer material 8 is transferred to the transfer target 3 by the heat transmitted from the flexible sheet 9 and the pressure of the fluid 11.
At this time, a pressure is applied to the transfer material 8 so that the transfer material 8 in a portion that is not transferred to the transfer material 3 extends beyond the breaking elongation in the groove 5, and as shown in FIG. Cut around.

Then, the fluid 11 is removed by the fluid discharge member 22.
Of the flexible sheet 9 and the heating member 17
Then, the support member 10 is raised as shown in FIG.

Thereafter, the feed roller 15 and the take-up roller 16 are driven to take up the cut transfer material 8 on the take-up roller 16, and the next transfer layer to be transferred is positioned in the transfer area. On the other hand, since the transferred material 3 is integrated with the base film 6, the base film 6 is peeled off after being taken out from the apparatus.

In this way, one cycle of the transfer process is completed.

The present invention is not limited to the above embodiments, but can be implemented in various other modes.

For example, in the embodiment, the mounting table 1 may be moved up and down with respect to the support member 10.

When the fluid 11 is supplied, the fluid 11 is supplied before the flexible sheet 9 comes into contact with the transfer material 8 to bring the flexible sheet 9 under pressure into contact with the transfer material 8. At the same time, it may be pressed against the transferred body 3 via the transfer material 8.

When the fluid 11 is discharged, the flexible sheet 9 may be discharged after the flexible sheet 9 is separated from the transfer material 8.

When the flexible sheet 9 is heated,
The flexible sheet 9 may be heated after coming into contact with the transfer material 8.

Further, as shown in FIG. 5, the supporting member 10
Has a volume sufficient to completely cover the transferred body 3, the bottom raising plate 2, and the frame body 4, and instead of the plate-shaped heating member 17, the flexible sheet 9 is indirectly provided via the fluid 11. A heating member 17 such as a heater for heating the above may be arranged on the inner bottom surface of the support member 10. When such a support member 10 is used, the mounting table 1 is a wall 1 for sealing.
