Abstract

PURPOSE:To make the separability of an object (or box) to be transfered better without causing the loosening of the edge portion of the object by heat and also the discoloration of the object by using a system in which a foil is clamped near the perimeter of an object and slightly lowered from the upside of the object to give the foil a tension, and then a press stamp is lowered. CONSTITUTION:A foil 1 is automatically sent out through guide rolls 9 from a sender 3 to a winder 2 and held by a clamp 7 in the neighborhood of the edge of the foil 1, where an object 5 to be transfered is centered. The clamp 7 is slightly lowered from the upside of the object 5, and a silicone rubber press stamp 4 heated is then lowered for transfering. When the temperature of the stamp 4 is raised (200 deg.C or lower), a slack is occurred in the object 5 by heat and a discoloration also takes place. When the temperature is too low, the separation of the object 5 takes place. Therefore, the temperature rise to 140 deg.C is adequate.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a hot stamp transfer method.

As is well known, the hot stamp transfer method is used to transfer products,
For example, due to the 1A eclipse of a home appliance product, the product will be eligible for gold r! This is a method to transfer the shiny and gorgeous λ wear.

Compared to other surface processing techniques such as resin plating, direct t'9 printing, and stamping, this hot stamping type transfer has the following advantages: l) The stamp machine is compact and does not require a large installation area;
2) Since melt cutting is not used, there is no need for anti-corrosion equipment. 3
) It is possible to precisely stamp even the roughest patterns, and the desired metallic tone can be easily obtained. 4) In addition to resin, it has a wide range of applications such as paper, cloth, and resin. 5) Tenyo Q9 has wear resistance and chemical resistance, and does not change over time.
6) Lighter application compared to using metal foil! 2 is widely used because it has the advantage of saving resources and meeting the goals of energy saving and energy saving.

[Conventional technology and its problems]

Conventional general hot scrubbing methods include a polyester resin film, a peeling layer, an i4ir layer, and a polyester resin film. uVF
A hot-stamped pink foil made of I- is coated with the 'lf layer on the transfer surface of a synthetic resin home appliance product, and the polyester resin film on the top surface is coated with a pressure stamp of silicone rubber heated to +50 t to 200°C. It is a stamp that transfers an image by pressing, and there are two types of pressure stamps made of soric rubber: flat and convex.
1-33455).

Further, as a special hot stamp type transfer method, the method shown in FIG. 3 is known. In the same figure, between the band-shaped hot stamping foil l + feeding 'Jff3 and the plotting device 2! ! A pressure stamp 4 made of gluecon rubber that can be moved up and down is provided approximately above the center of the frame, and an adherend 5 (for example, a housing of a home appliance) is faced downwardly with a transfer foil 1 in between. The adherend 5 is formed with inclined surfaces, and in order to transfer the violet layer to the 11J inclined surface 6, an elastic body is provided in the vicinity of the pressure stamp 4 and before and after the hot stamping foil l. Clamp 7 consisting of
．． At step 7, the pressure stamp 4 is lowered while holding the foil IrM and transferred.

Such general and′! When the transfer was performed using the special hot stamping transfer method shown in S3, in both cases, when the transfer was carried out by feeding the hot stamping foil l in the longitudinal direction, the inventor found that when the transfer was carried out in the longitudinal direction of the hot stamping foil l, It was discovered that poor foil cutting (jaggies) occurred in some directions.

In particular, in the case shown in Figure 3, the hot stamping foil 1 is held by the hot stamping knob 7.7 in order to prevent the knob from being stuck in the Q position. As a result, as mentioned above, even the fine inspection lines can be precisely stamped and the desired metal tone can be obtained.
There are 10 advantages of the stamp transfer method.

[Means for solving the problem] Therefore, the present invention, in order to eliminate such problems since iZ, changes the temperature Ut of the pressure stamp, changes the pressing force and pressing time, and , hot stamping foil 'A/ftl! This was created as a result of considering the shrinkage of the l rod and the wrong number of wiping lines. A pressurized stamp facing the 4414 body is provided at the center, and the foil is held with a clamp near the outer periphery of the adherend. This relates to the Honotosukun pink transfer method in which the pressure stamp is lowered when the foil is slightly lowered and tension is applied.

The following is a detailed explanation of the R-formation of the present invention 1 using examples. Fig. 1 is a schematic diagram of an apparatus for terminating the method of the present invention, and the process is (a) - (b) - They are shown in the order of (c).

In FIG. 1, parts that are the same as those shown in FIG. 3, which shows a conventional example, are designated by the same reference numerals, and their explanations are omitted. 71 of the stamp transfer on the upper surface of the speaker housing, which is the adherend 5, placed on the ! Do me.

That is, the foil is automatically fed out from the foil 2:y drawing out WW3 via the guide roll 9.9 to the cutting device 2.

Next, in (B), the foil 1 is held by the club 7 at a position near the outside of the edge of the foil 1 with the adherend 5 bound in the middle and LL-closed, and the shrift lamp 7 is held.
? ! It is lowered slightly from the upper surface of the human body 5.

As a result, the foil 1 imparts a bowing force of 5 to 10 kg/e- to the polyester base film 19. Therefore, the base film is elongated by a maximum of about 2.5%. Further, when the clamp 7 drips, it remains for 8 days, and the angle φ of the foil 1 is preferably α-25° or more, and the test results showed that α-30' was good.

The hole 17 is sufficiently large so as not to come into contact with the heating layer 10 and the adherend 5. When the core clamp 7 is lowered, a uniform tension is applied to the hot stamping foil 1 around the M attachment body 5.

Therefore, in the present invention, the hot stamping foil 1 is intermittently fed out, and in synchronization with this, the pressure stamp 4 is intermittently lowered to perform foil transfer.

Since the present invention is configured as described above, it has the following effects.

〔Effect of the invention〕

■ Layer breakage in foil transfer is improved without raising the temperature of the pressure stamp, or without increasing the pressing force or time, and the commercial value can be increased.
