【発明の詳細な説明】
〔産業上の利用分野〕
本発明は部材の表面の一部をマスキング材で保護して該
部分に表面処理が施されないようにするマスキング方法
−に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a masking method for protecting a part of the surface of a member with a masking material to prevent surface treatment from being applied to the part.
例えば自動車の床裏には防錆防音防振処理を施すために
ポリ塩化ビニルゾルやタールウレタン等の保護塗料が塗
装されている。このような保護塗料の塗装にあたり、例
えば自動車の床裏に存在する水抜き孔、ケーブル孔、ネ

材で保護することが行われている。またブラケット等の
部材を取付ける個所やボス等も保護塗料が付着しないよ
うにするために、該部分をマスキング材で保護すること
が必要である。For example, protective paints such as polyvinyl chloride sol and tar urethane are applied to the underside of automobile floors to provide anti-rust, sound and vibration-proof treatment. When applying such protective paint, in order to prevent the protective paint from adhering to the inside and periphery of holes such as water drain holes, cable holes, screw holes, and component through holes that exist under the floor of automobiles, for example. , the hole is protected with a masking material. Further, in order to prevent the protective paint from adhering to the parts where members such as brackets are attached, bosses, etc., it is necessary to protect these parts with a masking material.
上記自動車の床裏塗装にあたっては使用されるマスキン
グ材の数は実に２００個以上にもなる。In fact, more than 200 masking materials are used when painting the underside of the automobile floor.
このような多数のマスキング材を自動車製造ラインに支
障を生じないように迅速に所定部分に取付けるには多数
の熟練した作業員が必要になる。A large number of skilled workers are required to quickly attach such a large number of masking materials to predetermined parts without disrupting the automobile manufacturing line.
上記マスキング材としては従来粘着テープが用いられて
来たが、粘着テープではその都度所定の大きさ形状に切
取って保護個所に貼着しなければならないし、厚さが薄
いので塗装後室膜に埋没してしまって剥離が極めて困難
になる。Adhesive tape has conventionally been used as the masking material mentioned above, but with adhesive tape it is necessary to cut it into a predetermined size and shape each time and stick it to the protected area, and because it is thin, it is difficult to apply the adhesive tape after painting. It becomes embedded in the surface, making it extremely difficult to remove it.
従来、上記粘着テープに代わってポリスチレン発泡体等
のプラスチック発泡体を材料としたマスキング材が提供
されている（特開昭６４−４３３７６号、特開昭６４−
８５１７１号等）。このようなプラスチック発泡体を材
料とするマスキング材は容易に所定の形状に成形出来、
また厚さも大きくすることが出来るので、マスキング材
を保護個所に取付けたり、取はずしたりする作業が極め
て容易になる。また重要なことは、このようなマスキン
グ材はロボットを用いて保護個所に取付けたり取はずし
たりすることが出来ることである。Hitherto, masking materials made of plastic foams such as polystyrene foam have been provided in place of the above-mentioned adhesive tapes (Japanese Patent Laid-Open Nos. 43376-1986 and 1983-1999).
No. 85171, etc.). Masking materials made from such plastic foam can be easily molded into a predetermined shape.
Moreover, since the thickness can be increased, the work of attaching and removing the masking material to the protected area becomes extremely easy. It is also important that such masking materials can be applied and removed from protected areas using robots.
このようなロボットによるマスキング材の自動取付は取
はずしにあってはロボットに円滑にマスキング材を供給
することにある。The purpose of automatic attachment of the masking material by such a robot is to smoothly supply the masking material to the robot during removal.
ロボットにマスキング材を供給するにはコンベアーによ

することが考えられる。しかしながらロボットにおいて
はマスキング材の拾い上げ個所は固定されている。した
がってベルトコンベアの一定位置に動かないようにマス
キング材を載置することが必要である。In order to supply the masking material to the robot, it is conceivable to use a conveyor to transport the masking material from the collection location to the installation location. However, in a robot, the location from which the masking material is picked up is fixed. Therefore, it is necessary to place the masking material at a fixed position on the belt conveyor so that it does not move.
本発明は上記従来の課題を解決するための手段として、

マスキング方法を提供するものである。The present invention, as a means for solving the above-mentioned conventional problems,
The masking material (3) is placed on one end of the belt conveyor (1), and the masking material (3) is picked up by the mounting device (6) at the other end, and the masking material (3) is placed on the protected part of the member (10). The present invention provides a masking method in which an adhesive layer (2) is formed on the surface of the belt conveyor (1) on which the masking material (3) is placed.

Place it by fixing it to the In this way, the masking material (3) can be placed at a fixed location on the placement surface of the belt conveyor (1) without moving, and the other end of the belt conveyor (1) can be reliably placed on the robot attachment part W ( 6) can be picked up by
