〔産業上の利用分野〕
本発明は、腕時計用装飾カバーガラス特にサファイヤガ
ラスの着色方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for coloring decorative cover glass for wristwatches, particularly sapphire glass.
従来から腕時計カバーガラスに印刷、蒸着等により装飾
を施すことは行なわれている。また、カバーガラスに濃
度が徐々に変化する着色を施すことも行なわれている。BACKGROUND OF THE INVENTION Conventionally, wristwatch cover glasses have been decorated by printing, vapor deposition, etc. It has also been practiced to color the cover glass so that its density gradually changes.
この方法は、着色塗料をふきつける方法によっているが
、これは多数の製品を均一な仕上がりにすることがむず
かしい。アクリルガラスでは染料を入れた溶液中にガラ
スを浸漬し、徐々に引き上げることにより濃度が徐々に
変化したガラスを得ることができるが、この方法はアク
リルガラスのみにしか使えない。This method relies on spraying colored paint, but this method is difficult to achieve a uniform finish on a large number of products. For acrylic glass, it is possible to obtain a glass whose concentration gradually changes by immersing the glass in a solution containing a dye and gradually pulling it up, but this method can only be used for acrylic glass.
本発明はサファイヤガラスに濃度が徐々に変化する着色
を作業性よく、均一な仕上がりで施そうとするものであ
る。The present invention aims to apply coloring to sapphire glass in which the density gradually changes with good workability and a uniform finish.
サファイヤガラスに紫外線を照射するとサファイヤガラ
スが茶色に着色するという性質がある。Sapphire glass has the property of turning brown when exposed to ultraviolet light.
これはサファイヤガラス中に含まれる酸化チタンが紫外
線の作用により変質するためである。本発明はこの性質
を利用し、サファイヤガラスに照射する紫外線量を調節
することにより、着色濃度が徐々に変化するようにした
ものである。その方法は紫外線照射装置とサファイヤガ
ラスの中間にシャッターを設置し、シャッターを徐々に
開きながらサファイヤガラスに紫外線を照射することに
よる。This is because the titanium oxide contained in sapphire glass is altered by the action of ultraviolet light. The present invention utilizes this property to gradually change the coloring density by adjusting the amount of ultraviolet rays irradiated to the sapphire glass. This method involves installing a shutter between the ultraviolet irradiation device and the sapphire glass, and irradiating the sapphire glass with ultraviolet light while gradually opening the shutter.

シャッター３を設置し、このシャッター３を１５秒間か
けて１の上でαの位置からｂの位置まで段階的に移動さ
せ、さらに１５秒間かけてａの位置までもどした。この
動作は手動でも良いし、他の駆動源を用いても良い。Hereinafter, the present invention will be explained based on Examples. The drawings are schematic diagrams showing embodiments of the present invention. Ultraviolet rays are irradiated from the ultraviolet ray irradiation device 2. The 7-eye gazette 1 is placed at a distance of 206 nm from the ultraviolet irradiation device 2. Further, a shutter 3 was installed at a distance of 1 crn, and the shutter 3 was moved stepwise from the position α to the position b above the shutter 1 over a period of 15 seconds, and then returned to the position a over a further 15 seconds. This operation may be performed manually or by using another driving source.
この工程により、サファイヤガラス１のα近傍は茶色で
濃度が濃く、ｂ近傍では色かうすく着色された。As a result of this step, the sapphire glass 1 was colored brown with a high density near α, and was colored faintly near b.
この着色サファイヤガラスは紫外線照射条件を管理する
ことにより多数のサファイヤガラスを同じ仕上がりに仕
上げることができる。また、ガラス自体に着色しである
ため、剥離することはなく品質は安定している。This colored sapphire glass can be finished to the same finish by controlling the ultraviolet irradiation conditions. In addition, since the glass itself is colored, it does not peel off and the quality is stable.
本実施例に述べた以外にシャッターの形状、移動速度を
変えることにより種々の濃度変化のパターンを得ること
ができる。In addition to those described in this embodiment, various density change patterns can be obtained by changing the shape and moving speed of the shutter.
以上実施例に述べたように本発明によれば、す７アイヤ
ガラスに簡単に作業性よく均一な仕上力りで濃度が徐々
に変化する着色を施すことができる。As described in the embodiments above, according to the present invention, it is possible to easily and easily apply coloring to glass with a uniform finish with good workability and a gradual change in density.
