Summary:To realize micronization and uniformization of coating particle sizes in a rotary bell cup coater.SOLUTION: A rotary bell cup coater 1 includes: a feed tube 22 for ejecting a coating material from a tip; a bell cup 3 rotating about a central axis C of the feed tube 22; and a bell hub 5 which is provided on an inner peripheral side of the bell cup 3, and which has a concave cross section in a posture of directing the concavity to the feed tube 22. The bell hub 5 rotates about the central axis C together with the bell cup 3, and thereby the coating material ejected from the feed tube 22 toward an inner bottom surface 51 of the bell hub 5 is transferred to an inner peripheral surface of the bell cup 3 via an inner peripheral surface 52 and an end surface 53 of the bell hub 5.SELECTED DRAWING: Figure 1 【課題】回転ベルカップ塗装機において、塗料粒子径の微細化および均一化を実現する。【解決手段】回転ベルカップ塗装機１は、先端から塗料を吐出するフィードチューブ２２と、フィードチューブ２２の中心軸Ｃまわりに回転するベルカップ３と、ベルカップ３の内周側に設けられ、かつフィードチューブ２２に凹みを向けた姿勢とされた断面凹状のベルハブ５と、を備える。ベルハブ５は、ベルカップ３とともに中心軸Ｃまわりに回転することにより、フィードチューブ２２からベルハブ５の内底面５１に向って吐出された塗料が、ベルハブ５の内周面５２および端面５３を介してベルカップ３の内周面へ乗り移るように構成されている。【選択図】図１
