The flexible sheet 6 is caused to conform to the three-dimensional surface of the transfer medium 4 with the transfer material 5 therebetween, and the transfer material 5 is heated by the flexible sheet 6 to be adhered to the transfer medium 4. A base film of the transfer material 5 is peeled off the transfer medium 4, to obtain a product 7 made by forming a transfer layer being transferred generally on the three-dimensional surface of the transfer medium 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a transfer product in which a surface of a three-dimensional article is painted with a transfer material.

[0002]

2. Description of the Related Art Conventionally, there has been known a method for producing a transfer product which comprises the following steps in order to form a picture, a character or the like on the surface of various three-dimensional shaped articles such as home electric appliances, cosmetic containers, and ornaments. Has been.

First, the transferred body 4 is placed on a placing portion 1 having a plurality of suction holes 2 on the upper surface and a sheet fixing portion 3 on the periphery (see FIG. 2a).

Next, the transfer material 5 and the flexible sheet 6 are sequentially covered on the transfer target body 4, and the ends of the transfer material 5 and the flexible sheet 6 are fixed by the sheet fixing portion 3 (FIG. 2).
b)).

Next, the suction hole 2 provided on the upper surface of the mounting portion 1
The transfer material 5 and the flexible sheet 6 are made to follow the three-dimensional shape of the transferred body 4 by sucking more air, and the flexible sheet 6 that has been heated after the transfer material 5 is placed or before the transfer material 5 is moved. The transfer material 5 is heated by heat conduction to be thermally adhered to the transferred body 4 (see FIG. 2c).

Finally, the base film of the transfer material 5 is peeled off from the transferred body 4 to obtain a transfer product 7.

[0007]

However, in the conventional method, the ideal process progression as shown in FIG. 2 is rare. Since the transfer material 5 and the flexible sheet 6 have no air permeability, when the transfer material 5 and the flexible sheet 6 are fixed by the sheet fixing portion 3,
If air is sandwiched between the transfer material 5 and the transfer target 4 when the transfer material 5 is made to follow the three-dimensional shape of the transfer target 4, the air trap 9 may be formed and an air pocket 9 may be formed. If air is trapped in the air, there is a case where there is no escape path for the air and an air pool 9 is formed (see FIGS. 3a and 3b).

By forming the air pocket 9, the transfer material 5
The heat of the flexible sheet 6 is not transferred to the transfer material 5 at the portion where the air pocket 9 is formed between the transfer material 5 and the transfer-receiving member 4. Since the transfer material 5 does not adhere to the transferred material 4 in the formed portion, the transferred material 4
Transcription is incomplete (see Figure 3c).

Therefore, it is an object of the present invention to solve the above problems and to provide a method for producing a transfer product in which all the patterns to be transferred are formed on the three-dimensional surface of the transferred material.

[0010]

In order to achieve the above-mentioned object, a method of manufacturing a transfer product according to the present invention comprises (1) a mounting device having a plurality of suction holes on the upper surface and a sheet fixing portion on the periphery. A step of placing the transferred material on the portion, (2) a step of sequentially covering the transfer material and the flexible sheet on the transferred material and fixing the periphery of the transfer material and the flexible sheet with a sheet fixing portion, (3) a step of sucking air from the suction hole to bring the transfer material into close contact with the transfer target, (4) from the flexible sheet heated after the step of (3) or before the step of (3) The step of heating the transfer material by heat conduction to adhere it to the transferred material, (5) the step of peeling the base film of the transfer material adhered to the transferred material, and the transfer of sequentially performing the steps (1) to (5) above. In the product manufacturing method, a transfer material having a large number of fine holes is used as the transfer material.

[0011]

Since the transfer material having a large number of fine holes is used as the transfer material, when air is sandwiched between the transfer material and the flexible sheet when the sheet is fixed by the sheet fixing portion, or the transfer material is transferred. Even when air is sandwiched between the transfer material and the transfer target when the body is made to follow the three-dimensional shape of the body, if the air is sucked through the suction holes provided on the upper surface of the mounting portion, the transfer material and the flexible sheet are separated. Air between the transfer material and the transfer material 4 is also vented through the fine pores of the transfer material and eliminated. Therefore, by suction from the suction holes on the upper surface of the mounting portion, the flexible sheet is moved along the entire surface of the transfer target through the transfer material, and the heat of the flexible sheet is transferred to the entire transfer material.

The mounting portion 1 is constructed so as to have a plurality of suction holes 2 on its upper surface and a sheet fixing portion 3 on the periphery.

The mounting portion 1 is for mounting the transferred body 4 on the upper surface thereof. The sheet fixing portion 3 of the mounting portion 1 is provided with the transfer target 4
By fixing the periphery of the transfer material 5 and the flexible sheet 6 which are sequentially covered thereon, a closed chamber is formed. The periphery of the transfer material 5 as used herein refers to a portion surrounding a pattern to be transferred in one painting process and a region necessary for aligning the transfer material 5 with the transfer target 4, and the transfer material 5 It does not refer to the edge of 5. Further, in FIG. 1, the seat fixing portion 3
Is above the upper surface of the mounting portion 1, but may be the same as or lower than the upper surface of the mounting portion 1. The suction hole 2 on the upper surface of the mounting portion 1 is connected to a suction member such as a vacuum pump,
The suction member sucks the gas in the closed chamber through the suction hole 2.

The transfer material 5 is provided with a transfer layer such as a pattern layer and an adhesive layer on a base film having releasability, and has a large number of fine holes.

When sucking the gas in the closed chamber, the gas between the transfer material 5 and the flexible sheet 6 or between the transfer material 5 and the transfer target 4 is removed through the fine holes. As a method of forming a large number of fine holes in the transfer material 5, a method of forming a transfer layer on the base film and then making holes in the base film and the transfer layer with a thin laser beam or a needle-shaped material is used. Alternatively, a method is used in which the base film is resin-decomposed into a dot pattern by a chemical reaction such as a chemical, and the transfer layer is formed thereon. When the microscopic holes are provided in the pattern layer, the microscopic holes are formed in a size that is invisible to the naked eye.

The transfer material 5 may be either a roll or a sheet. When the roll-shaped transfer material 5 is used, a delivery roller and a take-up roller are arranged outside the mounting portion 1, and the transfer material 5 is fed from the delivery roller so that the pattern layer and the transferred body 4 face each other. Sent out. When the pattern layer is transferred to the transferred body 4, the transfer material 5 is moved by a predetermined pitch.
Is sent out from the sending roller, a new pattern layer and the transferred body 4 are opposed to each other, and the base film after peeling is wound by the winding roller.

The flexible sheet 6 has heat resistance and the transferred body 4
It is configured to have flexibility and stretchability that deform along the three-dimensional shape. As the material of the flexible sheet 6, for example, silicon rubber having a thickness of about 1 to 3 mm is used.

The flexible sheet 6 is heated on the transfer material 5 along the three-dimensional shape of the transfer material 4 via the transfer material 5 by suction from the suction holes 2 of the mounting portion 1 to be transferred to the transfer material 4. Let it adhere.
The flexible sheet 6 is heated by a heater or the like in order to thermally bond the transfer material 5 to the transfer target 4, but the flexible sheet 6 is deformed before being fixed by the sheet fixing portion 3. It may be either inside or after the transfer target 4 has been conformed to the three-dimensional shape.

Using the above transfer device, the transfer product 7 is manufactured as follows.

First, as shown in FIG. 1A, the transferred body 4 is placed on the placing portion 1.

Next, the transfer material 5 and the flexible sheet 6 are sequentially covered on the transfer target 4, and the periphery of the transfer material 5 and the flexible sheet 6 are fixed by the sheet fixing portion 3.

Next, as shown in FIG. 1b, the flexible sheet 6 is deformed by sucking air from the suction holes 2 provided on the upper surface of the mounting portion 1, and the transfer material 5 and the flexible sheet 6 are also deformed. Between the transfer material 5 and the transfer material 5 and the transferred material 4 is also aspirated by the fine holes of the transfer material 5 for aeration 8.

Next, as shown in FIG. 1c, the flexible sheet 6 is placed along the three-dimensional shape of the transferred body 4 with the transfer material 5 interposed therebetween.
The transfer material 5 is heated by the flexible sheet 6 and adhered to the transfer target 4.

Finally, the base film of the transfer material 5 is peeled off from the transfer object 4, and as shown in FIG. 1d, the transfer product 7 in which the transfer layer to be transferred is entirely formed on the three-dimensional surface of the transfer object 4. To get

The method of manufacturing the transfer product 7 of the present invention is not limited to the above-described embodiment, and for example, the flexible sheet 6 can be made more easily conformed to the three-dimensional shape of the transferred object 4,
The flexible sheet 6 may be pressed from the back side for the purpose of shortening the time for adhering the transfer material 5 to the transferred body 4. As a method for applying pressure from the back surface of the flexible sheet 6, a method in which a pressing member such as an elastic pad made of silicon rubber is moved forward by an air cylinder or the like to mechanically apply pressure to the flexible sheet 6 or water or the like is used. There is a method of pressurizing the flexible sheet 6 by supplying a fluid to the space behind the flexible sheet 6. In particular, when the flexible sheet 6 is pressed by a fluid, the flexible sheet 6 can be easily fitted to the transferred body 4 having a three-dimensional shape, and it is necessary to design the flexible sheet 6 according to the shape of the transferred body 4 like a pressing member. There is no. As the fluid, in addition to the above-mentioned water, for example, a liquid such as oil or a gas such as steam or compressed air is used. In addition, heating the fluid in advance improves the heating efficiency. The pressurization of the flexible sheet 6 by the fluid may be started before being fixed by the sheet fixing portion 3, during the deformation of the flexible sheet 6, or after the deformation.
