本発明は、気孔を含む柔軟なフオーム材の表面にレーザ
を用いて文字や図形などを彫刻する方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for engraving characters, figures, etc. on the surface of a flexible foam material containing pores using a laser.
従来から、通常のプラスチックやゴムの表面に文字や図
形などを彫刻する場合には、その文字や図形に対応した
凸部を有する金属ごて等を加熱して押し当てる方法が一
般に行なわれている。Conventionally, when engraving letters or figures on the surface of ordinary plastic or rubber, the general method used is to heat and press a metal iron, etc. that has a protrusion corresponding to the letter or figure. .
しかし、この方法は通常の硬いプラスチックやゴムには
適用でさるものの、プラスチックフオームやラバーフォ
ームのように気孔（セル）を含んだ柔らかいフォーム材
は熱による溶融が激しい為、この方法でフォーム材に文
字や図形を元の形状通りに彫刻することは不可能であっ
た。However, although this method is applicable to ordinary hard plastics and rubber, soft foam materials containing pores (cells) such as plastic foam and rubber foam melt rapidly due to heat, so this method cannot be applied to foam materials. It was impossible to engrave letters and figures exactly as they were originally.
一方、最近ではレーザ加工技術が金属や宝石等の切断や
穴あけなどに利用され、一部ではレーザを用いて文字や

ようになってさた。例えば、半導体関係ではマスキング
した素子表面にＹＡ（ｉレーザを照射し、−回の照射で
小さなロフト番号などを彫刻する例がある。On the other hand, recently, laser processing technology has been used for cutting and drilling metals, jewelry, etc., and in some cases, laser engraving, which uses lasers to engrave characters and figures on the surface of materials, has come into use. For example, in the semiconductor field, there is an example in which a masked element surface is irradiated with a YA (i-laser) and a small loft number or the like is engraved by -times of irradiation.
しかしながら、現在までのところレーザ彫刻も特殊な分
野に限られ、プラスチックやゴムのフオーム材に適用し
た例は知られていない。However, to date, laser engraving has been limited to special fields, and there are no known examples of its application to plastic or rubber foam materials.
上記した通り、気孔を含む柔軟なフオーム材には文字や
図形などの凹部を明瞭でしかも美しく彫刻することが極
めて難しく、その為の適当な方法が知られていなかった
。As mentioned above, it is extremely difficult to engrave clear and beautiful recesses such as letters and figures on flexible foam materials containing pores, and no suitable method for this purpose has been known.
本発明は、気孔を含むプラスチック又はゴムのフォーム
材の表面に、文字や図形などを原図に忠実に明瞭且つ美
しく彫刻する方法を提供することを目的とする。An object of the present invention is to provide a method for engraving characters, figures, etc. clearly and beautifully on the surface of a plastic or rubber foam material containing pores, faithfully to the original drawing.

オームがあり、いずれも本発明方法を適用できる。(Means for Solving the Problems) The method for engraving a foam material according to the present invention is to form a foam material directly on the surface of the foam material on which a mask T having holes corresponding to the original drawing is placed, or by numerical control according to the original drawing. on the surface of the material,
〇Foam material is a plastic material whose apparent density is reduced due to the presence of independent or continuous pores throughout the surface. Plastic foams include polyurethane foam, polyvinyl chloride foam, polyethylene foam, etc., and rubber foams include natural rubber, styrene-butadiene rubber, nitrile rubber, etc., to which the method of the present invention can be applied. .

マスキングするか、若しくは各種の加工機械に応用され
ている数値制御（Ｎ Ｏ）方式を利用することができる
。As a laser, a YAG laser or a carbon dioxide laser that can obtain high output is preferable, but other lasers such as those that emit ultraviolet rays or visible light may also be used as long as they can irradiate sufficient energy to melt and vaporize the foam material. I do not care. In order to prevent excessive melting of the foam material, the laser beam needs to be scanned in parallel at an appropriate speed and pitch.In addition, as a means of irradiating the scanning laser beam only to desired positions on the surface of the foam material, It is possible to mask the surface of the foam by placing a mask made of a material such as metal that can block the irradiated laser beam, or by using a numerical control (NO) method applied to various processing machines.
本発明においては、走査するレーザ光が極めて少ない出
力でフォーム材を表面で溶融させる。フオーム材は気孔
が多いので、表面で溶融してその場に球状に付着して固
まらず、飛散して原図通りの明瞭な凹部が形成される。In the present invention, the scanning laser beam melts the foam material at the surface with extremely low power. Since the foam material has many pores, it melts on the surface and adheres to the spot in a spherical shape, but does not harden and scatters, forming a clear concave portion as shown in the original drawing.
彫刻された四部にはレーザの出力や走査速度及びフォー
ム材の材質などに応じて焦げ跡がつき、凹部以外の表面
とは異なる特有の色調が得られる。Depending on the laser output, scanning speed, foam material, etc., the four engraved parts will have scorch marks, resulting in a unique color tone that is different from the surface other than the recessed parts.

深さ、凹部の表面状態及び凹部の焦げ跡の状態などにも
影響を与える。The depth of the recess to be engraved, the surface condition of the recess, the state of burnt marks on the recess, etc. can be adjusted by adjusting the laser output, the scanning speed and pitch of the laser beam, the aperture of the focus of the laser beam, etc. Furthermore, if assist air is blown at the same time as the laser beam irradiation, the melted foam material is completely scattered and a beautiful finished state of the concave portion can be stably obtained. At the same time, the flow rate of the assist air also affects the depth of the recess to be engraved, the surface condition of the recess, the state of scorch marks on the recess, and the like.
