Description
本発明は、包括的には、材料塗布システム、例えば限定はされないが粉体コーティング材料塗布システムに関する。より詳細には、本発明は、洗浄時間及び色交換時間を短縮し、使いやすさを改善するアプリケーターに関する。
本願は、「POWDER APPLICATOR WITH PATTERN ADJUSTMENT」として2003年8月18日に出願された係属中の米国仮特許出願第60/481,250号、「POWDER SPRAY APPLICATOR」として2003年11月18日に出願された係属中の米国仮特許出願第60/523,012号、及び「POWDER COATING MATERIAL SPRAY GUN」として2004年3月19日に出願された係属中の米国仮特許出願第60/554,655号の優先権を主張する。この引用により、上記全ての出願の全ての開示内容を、本明細書に完全に援用される。
材料塗布システムは、1つ又は複数の材料を1つ又は複数の層で物体に塗布するために用いられる。一般的な例は、粉体コーティングシステム、食品加工産業、医薬品、電子産業、及び製品組み立てに用いることができるような他の粒子材料塗布システム、絶縁保護コーティングをプリント回路基板に、又は接着剤を表面に塗布するような液体スプレーシステム、及び液体塗料スプレーシステムである。これらは、材料を物体に塗布するのに用いられる様々な多くのシステムのほんの数例にすぎない。
本発明は、粒子材料用のスプレーアプリケーターに関するいくつかの新たな態様を意図している。スプレーアプリケーターは、粒子材料の濃厚相流を用いる材料塗布システムと組み合わせると特に有用である。「濃厚相」とは、粒子流中に存在する空気が給送ホッパ等の供給源における材料を流動化するのに用いられる空気の量とほぼ同じであることを意味する。本明細書で用いる場合、「濃厚相」及び「高密度」は、空気搬送システム内の材料流の低空気体積モードという同じ概念を伝えるために用いられ、この場合、材料粒子の全てが懸濁状態で搬送されるわけではない。このような濃厚相システムでは、材料は、極めて少ない空気体積で流路に沿って押し進められ、材料は、どちらかというと流路に沿って互いに押し固まる栓の性質を帯びて、或る意味では流路内でピストンとして栓を押すようにして流れる。流路の断面が小さいほど、より低い圧力でこの移動を行わせることができる。
