Abstract: Provided is an application method including: a feeding step including feeding a viscous material to a discharge member; a temperature measurement step including measuring a temperature of the viscous material in a flow path through which the viscous material is fed to the discharge member; a pressurizing step including pressurizing the viscous material fed to the discharge member, based on the temperature measured in the temperature measurement step; and a discharge step including discharging, through the discharge member, the viscous material pressurized in the pressurizing step.

Abstract: An electrostatic coating device is provided with a housing, which has a cascade housing section that houses a cascade, and a motor housing section that houses an air motor. A clearance between the cascade and the inner wall of a first housing hole forms a first air flow passage. Furthermore, an annular clearance between the air motor (specifically, an air turbine) and the inner wall of a motor chamber forms a second air flow passage. The first air flow passage and the second air flow passage are communicated with each other via, for instance, a third air flow passage that includes a first communication passage, a circular recessed section, a second communication passage, and a third communication passage.

Abstract: A coating device includes: a rotating shaft; outer members; and an inner member connected to at least one of the outer members. The inner member includes: a cylindrical body which is connected to at least one of the outer member and includes an annular opening continuing to a coating-material diffusion surface of the outer member; a disk-shaped lid which is provided on the inner side of the opening and has an outer peripheral edge part of a smaller diameter than the opening; and a supporting part which connects the lid and the body. A rear surface of the lid and an inner peripheral surface of the body form a coating-material reservoir. An annular slit is formed between the outer peripheral edge part of the lid and the opening. The supporting part is provided more inside in the radial direction than the slit when viewed along an axial line.

Abstract: Provided is a coating device capable of suppressing condensation from forming on a joint ring that connects a robot arm and a rotary atomization head. 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.
