A rotary atomizing head includes an outer peripheral surface washing passage open onto an atomizing head outer peripheral surface for causing wash fluid supplied from a feed tube to flow out into an annular clearance between the rotary atomizing head and a shaping air ring. An outflow opening of an outflow passage constituting the outer peripheral surface washing passage is provided in a position closer to the backside into the annular clearance by a length dimension than a front end surface of a front ring section constituting the shaping air ring. Further, the outflow opening opens to the annular clearance in an angle that is an acute angle to the atomizing head outer peripheral surface.

The coating machine is provided with an air motor (3), a rotational shaft (4) that is rotatably supported by the air motor (3), a feed tube (5) that extends to a tip end of the rotational shaft (4) through the inside of the rotational shaft (4), a rotary atomizing head (6) that is mounted to the tip end of the rotational shaft (4), and a shaping air ring (7) that surrounds an outer periphery of the rotary atomizing head (6) and an axial tip end of which is arranged in back of a paint releasing edge (6D) of the rotary atomizing head (6). The shaping air ring (7) includes a great number of first shaping air spurting holes (9), and a great number of second shaping air spurting holes (10). An inner diameter dimension (d1) of the first shaping air spurting hole (9) is set to be larger than an inner diameter dimension (d2) of the second shaping air spurting hole (10). The number (N2) of the second shaping air spurting holes (10) is set to be smaller than the number (N1) of the first shaping air spurting holes (9).

A painting device is provided with: a bell-shaped cup for discharging paint; a housing for holding the cup so as to be freely rotatable; and first tip openings disposed on the outside in the radial direction on the base end side of the tip side outer peripheral edge of the cup and throwing paint onto a workpiece by spraying shaping air in the direction of the tip. When a tangent line that is tangent to the tip side outer peripheral edge of the cup from a first tip opening is drawn in a front view of the painting device, the first tip opening sprays shaping air at an inclination more to the inside in the radial direction of the cup than the tangent line.

Rotating projector for a coating product including a spraying device having a circular spraying edge, driving means for driving the spraying device around a rotational axis, a body including primary openings arranged on a primary contour for ejecting primary air jets in a primary direction. The air jets having an axial component and an orthoradial component which are nonzero. The primary direction has a nonzero radial component, which is centrifugal relative to the rotation axis. Each primary jet extends along the rotational axis at a distance from the rotational axis than the radius of the spraying edge. The body includes secondary openings arranged on a secondary contour for ejecting the secondary air jets in a secondary direction having axial and centripetal radial components. The secondary jets hit an external surface of the spraying device. The contours coincide with a circle centered about the rotation axis.

The joint ring 20 of this coating device 1 has an insulating member 23 which is positioned between a joint ring body 21 and a cover member 22, positioned so as to cover the joint ring body 21, and positioned so as to be separated from the cover member 22 by only a prescribed distance. In addition, the joint ring 20 is equipped with: a first chamber 230 that connects a first discharge port 212 and a second intake port 221, and is formed between the joint ring body 21 and the insulating member 23; and a second chamber 240 formed between the cover member 22 and the insulating member 23.

A spray device that atomizes and applies coating material to a coating target object includes a tip portion provided with a coating material supply port to supply coating material, an atomizing air supply port to supply air designed to atomize the supplied coating material, a plurality of pattern air supply ports to supply pattern air designed to adjust a spray width of the supplied coating material onto the coating target object, and first twisted supply paths to each of the pattern air supply ports, and a shielding plate that is provided adjacent to the outside of the pattern air supply ports and protrudes from a lower surface of the spray device toward the coating target object to prevent inflow of air outside an outer wall of the spray device.

An electrostatic atomizer can include an applicator rotatably attached to a distal end of a turbine and a shaft; and an applicator washing component comprising a solvent fluid line configured to separately dispense a cleaning solvent to an external applicator surface by an external solvent line and an internal applicator surface by an internal solvent line, wherein the cup washing component is distinct from a coating fluid line.

The disclosure relates to a coating method for coating a component with a coating agent, comprising the following steps: moving an application device over a component surface of the component to be coated, delivering a coating agent jet (9) from the application device to the component surface that is to be coated, defining switching points on the component surface for initiating a switching action, in particular for switching on or switching off a coating agent jet, and performing the switching action when one of the switching points is reached.

The disclosure provides the following steps: marking the switching points on the component surface by generating a switching marking on the component surface at the individual switching points, detecting the switching markings corresponding to the individual switching points during movement of the application device, and performing the switching actions when the switching markings are detected on the component surface.
