The rotary atomizing coating device () is provided with a spray head () formed of a tube body having a circular truncated conical shape and constituted to spray, from an opening end on the large diameter side, a coating introduced from an opening end on the small diameter side thereof, and a coating supply machine () engaged with the spray head () for supplying the coating while rotating the spray head () around an axial line (O). The spray head () has a first coating diffusion part () having a curved surface with a convex shape towards the axial line (O) on the inner peripheral surface, and a second coating diffusion part () extending to an outer edge () of the opening end on the large diameter side having a curved surface with a concave shape towards the axial line (O) with grooves () on the outer edge ().

Rotary atomizing coating device and spray head

Provided are a coating apparatus which coats an article using a plurality of coating nozzles and is capable of performing the coating without restriction of the posture of the article, a coating nozzle used for the same, and a coating method. A coating apparatus includes: a first air jet port; a plurality of coating material jet portsdispersedly disposed in the periphery of the first air jet portacross the whole circumference; and a plurality of second air jet portsdispersedly disposed in the periphery of the coating material jet portsacross the whole circumference. The coating apparatus includes a plurality of coating nozzleseach of which performs jetting via a circulating passage formed along the dispersing arrangement of the second air jet ports. A controlling unitindependently controls individual adjusting units of the plurality of coating nozzles

Coating nozzle, coating apparatus, and coating method using the same

A rotary atomization coating device is provided with a rotary atomizing head including a paint storage and adapted to atomize paint supplied to the paint storage and to discharge the paint onto a work, and a paint supplying nozzle adapted to supply the paint to the paint storage. The rotary atomizing head includes a plurality of bell cups. Each of the bell cups includes, at a front face thereof, a paint discharging face adapted to thin the paint by a centrifugal force. The rotary atomizing head includes a plurality of paint supplying holes corresponding to the respective bell cups. The paint supplying holes are adapted to supply the paint from the paint storage to the respective paint discharging faces. A plurality of grooves extending along a radial direction of the rotary atomizing head are formed at circumferential portions of the respective paint discharging faces.
