Abstract: A coating method is provided which includes the steps of applying a base paint on a workpiece, blowing air at 19° C. or higher and 26° C. or lower to the applied base paint to pre-dry the base paint, applying a clear coating on the pre-dried base paint, and finally drying the workpiece with the clear coating applied thereon.

Abstract: A liquid mixing device and a liquid mixing method are provided, which can suppress air from being mixed into liquids to generate air bubbles, and the structure is easy to clean, so that a high-quality mixed liquid can be obtained. The liquid mixing device is suitable for mixing multiple liquids and includes a stirring chamber; a supply portion, disposed on an inner surface of the stirring chamber to supply the liquids into the stirring chamber; a stirring component, disposed in the stirring chamber to stir the liquids supplied into the stirring chamber; and an opposing plate, disposed on the stirring component and disposed opposite to the supply portion.

Abstract: A liquid-mixing apparatus used in a liquid-mixing method comprises a plurality of supply valves provided to a cylinder. The supply valves make it possible to individually supply a plurality of types of liquids into a retention chamber. Each of the supply valves is configured so as to be switchable between an open state, in which the interior of a supply channel via which a liquid is supplied and the interior of the retention chamber intercommunicate, and a closed state, in which communication between the supply channel and the retention chamber is blocked. A piston moves in the direction in which the volume of the retention chamber increases while at least one of the supply valves is in the open state, whereby a liquid is drawn into the storage chamber.

Abstract: A painting system used in a painting method in which a plurality of colors of paint supplied from a paint supply device are mixed and toned with a mixing device and applied to a workpiece, the painting system comprising a storage unit that can store the paint that is mixed and toned with the mixing device, and a cleaning unit that can clean the mixing device. When applying the paint in the storage unit to the workpiece, the cleaning unit cleans the mixing device.

Abstract: 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 20; a plurality of coating material jet ports 22 dispersedly disposed in the periphery of the first air jet port 20 across the whole circumference; and a plurality of second air jet ports 24 dispersedly disposed in the periphery of the coating material jet ports 22 across the whole circumference. The coating apparatus includes a plurality of coating nozzles 18 each of which performs jetting via a circulating passage formed along the dispersing arrangement of the second air jet ports 24. A controlling unit 34 independently controls individual adjusting units of the plurality of coating nozzles 18.

Abstract: A coating apparatus has a rotary atomizing head that discharges paint to a work, and an air injecting unit that injects annular shaping air towards an outer peripheral edge portion of the rotary atomizing head. The air injecting unit has first air injecting ports and second air injecting ports. First air of relatively high wind speed is injected from the first air injecting ports and second air of relatively low wind speed is injected from the second air injecting ports.

Abstract: An intermediate reserve tank for temporarily storing a conductive coating medium is provided in a coating medium supply passage for supplying the conductive coating medium from a color switch valve mechanism to a spray gun. A block valve mechanism for electrically insulating the color switch valve mechanism and the intermediate reserve tank is provided. A coating medium extrusion portion for supplying water or a cleaning solution is connected to a transmission passage between the intermediate reserve tank and the spray gun via a switch valve. When an amount of the coating medium necessary until an end of a coating operation becomes a predetermined amount, the conductive coating medium is extruded by the water or the cleaning solution by switching the switch valve.
