【発明の詳細な説明】 ［産業上の利用分野］ 本発明はベル型塗装機のベルカップ洗浄方法に関す
る。さらに詳しくは、ベルカップの内部などに付着した
塗料や油汚れをきれいに洗浄してつぎの塗装工程におけ
る色ブツの発生を防止しうる洗浄方法に関する。TECHNICAL FIELD The present invention relates to a bell cup cleaning method for a bell type coating machine. More specifically, the present invention relates to a cleaning method capable of cleanly cleaning paints and oil stains adhering to the inside of a bell cup or the like to prevent color spots from being generated in the next coating step.
［従来の技術］ 従来より自動車ボデーなどの塗装には高速回転するベ
ルカップにより塗料を霧化して塗装するベル型回転霧化
式塗装機（以下、ベル型塗装機という）が多く用いられ
ている。[Prior Art] Conventionally, a bell-type rotary atomization type coating machine (hereinafter, referred to as a bell-type coating machine) that atomizes the paint by a bell cup that rotates at high speed and is used for painting automobile bodies and the like has been widely used. .
そのようなベル型塗装機には洗浄用のシンナーを洗浄
ノズルから噴射し、あるいはさらに洗浄ノズルの下方か

塗料を洗い落すようにした洗浄装置が取りつけられてお
り、それによって色替え後の塗装工程において色替え前
の塗料が一緒に噴霧されないようにしている（実開昭61
−106362号公報参照）。In such a bell-type coating machine, a thinner for cleaning is sprayed from the cleaning nozzle, or air is further sprayed from below the cleaning nozzle to wash off the paint before color change adhering to the bell cup. A cleaning device is installed so that the paint before the color change is not sprayed together in the painting process after the color change.
-106362).
［発明が解決しようとする課題］ 従来のベル型塗装機に内蔵されている洗浄装置では、
洗浄を充分に行なっても色ブツ（塗装面に色替え面の硬
化前の塗料および硬化した塗料片が斑点状に付着した状
態）のなどの不具合が発生することがある。[Problems to be Solved by the Invention] In the cleaning device built in the conventional bell type coating machine,
Even if the washing is sufficiently performed, problems such as color spots (a state in which the paint before hardening of the color changing surface and the hardened paint pieces adhere to the painted surface in spots) may occur.
その原因としてはベルカップの洗浄時に飛び散った燃
料を含む洗浄液が飛散防止用の円筒状フランジに付着し
たのち、シェーピング用エアーリングのエアー孔に垂れ
落ち、生乾きの状態になったものが色替え後の塗装時に
前記エアー孔から吹き出すエアーと一緒に噴霧されてし
まうことなどにあると考えられる。The reason for this is that after cleaning liquid containing fuel that has been scattered during cleaning of the bell cup adheres to the cylindrical flange for preventing scattering, it drops into the air hole of the shaping air ring and becomes a dry state after color change. It is considered that the water is sprayed together with the air blown from the air holes at the time of coating.
本発明は叙上の実情に鑑み、円筒状フランジなどに洗
浄液を付着させるおそれがなく、しかも一層充分にベル
カップの色替え前の塗料を洗浄しうるベルカップ洗浄方
法を提供することを目的としている。In view of the above circumstances, the present invention has an object to provide a bell cup cleaning method capable of cleaning the paint before the color change of the bell cup more sufficiently without the risk of attaching the cleaning liquid to the cylindrical flange or the like. There is.
［課題を解決するための手段］ 本発明のベルカップ洗浄方法は、ベル型塗装機から取
り外したベルカップを有機溶剤を主成分とする洗浄液に
浸し、ついで取り出したベルカップを水中で超音波洗浄
することを特徴としている。[Means for Solving the Problems] The bell cup cleaning method of the present invention is performed by immersing the bell cup removed from the bell type coating machine in a cleaning liquid containing an organic solvent as a main component, and then ultrasonically cleaning the bell cup taken out in water. It is characterized by doing.
かかる方法において、超音波洗浄を行なった後のベル
カップを、さらにシンナーガンでスプレー洗浄するする
のが好ましい。In this method, it is preferable that the bell cup after ultrasonic cleaning is further spray-cleaned with a thinner gun.
［作 用］ ベルカップを所定時間有機溶剤を主成分とする洗浄液
中に漬けておくと、ベルカップの内部などに付着した色
替え前の塗料に有機溶剤がしみ込み、塗料の一部は剥離
して落ち、残りもその付着力が弱まる。[Operation] When the bell cup is immersed in a cleaning solution containing an organic solvent as the main component for a certain period of time, the organic solvent permeates into the paint on the inside of the bell cup before the color change, and part of the paint peels off. Then, it will fall off, and the adhesive strength will weaken for the rest.
ついでその状態をベルカップを水槽内に入れて超音波
洗浄を行なうと、残余の塗料がすべてベルカップの表面
から除去され、洗浄にされる。Then, the bell cup is put in a water tank and ultrasonically cleaned in this state, and all the remaining paint is removed from the surface of the bell cup for cleaning.
なお水槽から取り出されたベルカップには洗浄液や水
分が付着しているので、シンナーガンでそれらを洗い落
したのち、再びベル型塗装機に取りつけてつぎの塗装を
行なえばよい。Since the cleaning liquid and water are attached to the bell cup taken out of the water tank, the bell cup may be washed off with a thinner gun, and then mounted again on the bell type coating machine to perform the next coating.
