【発明の詳細な説明】
〔産業上の利用分野〕
この発明は、塩化とニール樹脂製シート材、合成皮革な
ど熱可塑性シート材に、、比較的広い面積を存する立体
的な凹凸模様を施し、その表面にきれいな箔押し加工を
施すことができる高周波誘電加熱による立体箔押し方法
および高周波箔押し装置に関する発明である。[Detailed Description of the Invention] [Field of Industrial Application] This invention provides a three-dimensional uneven pattern having a relatively wide area on a thermoplastic sheet material such as a sheet material made of chloride/neel resin or synthetic leather. This invention relates to a three-dimensional foil stamping method and high frequency foil stamping device using high frequency dielectric heating, which can perform a beautiful foil stamping process on the surface.
従来の箔押し加工は、文字など比較的狭い面積のものを
平面に施すのが普通である。Conventional foil stamping typically involves stamping relatively small areas such as letters on a flat surface.
箔押しの加工面を立体的に現わす方法として、−旦平面
に箔押しした部分を、同じ形状の型で窪ませて凹溝とし
、凹溝内の底面に箔が存在するようにしたものがある。One way to make the foil-stamped surface appear three-dimensional is to use a mold of the same shape to make a groove in the foil-stamped area, so that the foil is present on the bottom of the groove. .
また逆に、箔押し部分を膨らませることも試みられてい
る。Conversely, attempts have also been made to inflate the foil stamped area.
しかしながら、箔押し部の幅が１センチメートル以上、
数センチメートルにも及ぶ広い面の箔押し、特に立体的
に複雑な形状で突出する表面全体に箔を付着させるよう
なものは存在しなかった。However, if the width of the foil stamping part is 1 cm or more,
There was no such thing as foil stamping over a wide area of several centimeters, especially when foil was applied to the entire protruding surface of a complex three-dimensional shape.
箔押し用の箔原紙は、フィルム表面に金属を蒸着させ、
その金属表面に熱接着剤をコーティングするのが普通で
あり、被処理材の表面に押圧転写し、かつ加熱接着させ
ることによって剥離しない箔押し加工が施されるもので
ある。Foil base paper for foil stamping is made by vapor-depositing metal on the surface of the film.
It is common to coat the metal surface with a thermal adhesive, which is then pressure-transferred onto the surface of the material to be treated and heat-adhered to achieve a non-peelable foil stamping process.
ところが、上記箔原紙の金属層の厚みは３ミクロン程度
と非常に薄いものであるため、広い平面に均等な力で箔
押しすること自体が困難で箔切れを生じ易い、仮に所定
の平面に箔押しすることができたとしても、従来技術を
応用して箔押し面に立体的な凹凸を施＼すと、表面積が
変化し、箔が被処理材の表面から剥離、もしくは箔切れ
してしまい美しい立体的な箔押し面とすることができな
い。However, since the thickness of the metal layer of the base foil paper is very thin, about 3 microns, it is difficult to stamp the foil over a wide flat surface with even force, and the foil tends to break. Even if it were possible to apply conventional techniques to create three-dimensional irregularities on the foil stamping surface, the surface area would change and the foil would peel off or break off from the surface of the material being treated, resulting in a beautiful three-dimensional shape. The surface cannot be stamped with foil.
このような点に鑑み、本発明は、塩化ビニール樹脂製シ
ート材などの比較的広い面積で、しかも立体的な凹凸表
面に、美しい箔押し加工を施すことができる方法および
その装置を発明したものである。In view of these points, the present invention has devised a method and an apparatus for applying a beautiful foil stamping process to a relatively wide area and three-dimensional uneven surface of a vinyl chloride resin sheet material, etc. be.
本発明に係る方法は、高周波誘電加熱によって、加熱条
件下で押圧し、凹凸の塑性加工及び箔押し加工を同時に
行なうものとする。In the method according to the present invention, pressing is performed under heating conditions using high-frequency dielectric heating, and plastic processing of unevenness and foil stamping are performed simultaneously.

）を介在させて加熱、押圧するものどする。In this method, a desired three-dimensional shape is carved by unevenness, and a pair of male mold (4) and female mold (4) made of conductive material are formed.
5) is used. One of the male type (4) and female type (5) is fixed to the upper electrode (7) of the high frequency dielectric heating device, and the other to the lower electrode (8), and the gap between the male type (4) and the female type (5) is fixed. The foil base paper (6) and the treated material (1), which is a thermoplastic sheet material, are
) is used to heat and press the material.
このとき、一対のオス型（４）とメス型（５）は嵌合状
態において、凹凸の所望形状が刻設されている形状加工
部（４ａ） 、 （５ａ）以外の外方部に比較的大きな
隙間Ｘを生じるようにする。At this time, when the pair of male mold (4) and female mold (5) are in the fitted state, there is a relatively large area on the outer part other than the shape-processed parts (4a) and (5a) in which the desired shape of unevenness is engraved. Create a large gap X.

理材（１）が型に沿って変形するとともに、箔原紙（６

) is pressed with an even force against the uneven surface of the material to be treated (1),
The metal layer is transferred as a foil (3).

When the male die (4) and the female die (5) are pressed together at a portion other than (5a), the foil will be transferred to that portion as well.
また、挟圧されなくても箔原紙と被処理材が接すると箔
原紙表面の熱接着剤が作用し、やはり一部が転写される
可能性がある。In addition, even if no pressure is applied, when the base foil paper and the material to be processed come into contact with each other, the thermal adhesive on the surface of the base foil paper acts, and there is still a possibility that a portion of the foil base paper may be transferred.
