Abstract: An electrostatic coating machine comprising at least two paint tanks (13A, 13B) for pushing out a paint by a pressure of a hydraulic fluid which one attached to a rotary base (14) while being electrically insulated form each other, and can be positioned to a coating position opposing to the machine body (3) by the rotation of the rotary base (14) such that while one paint tank is at the coating position, the other paint tank is engaged with a paint charging attachment (22) that is disposed being electrically insulated from the machine body (3) and has a paint supply port (Ps) for supplying a cleaning fluid and a paint of a next color and a drain recovery port (Dr) for recovering drains. Cleaning/paint charging time can be shortened to improve operation efficiency and insulation countermeasure for the paint supply system can be saved.

Abstract: PROBLEM TO BE SOLVED: To make it possible to decrease the stained parts where a conductive coating material sticks to the front ends of couplers and to easily wash these parts even if the coating material sticks thereto at the time of supplying the coating material by engaging and disengaging the couplers interposed in a coating material flow passage for supplying the coating material. SOLUTION: Respective valves 7, 8 formed at the respective couplers 9A, 9B are opened and formed to the front faces of the couplers 9A, 9B where their coating material inlet/outlet ports 7a, 8a face each other at the time of engagement. Valve disks 7b, 8b energized to close the coating material inlet/ outlet ports 7a, 8a from the inner side are disposed in the valves 7, 8. Operating elements 7d, 8d to open the coating material inlet/outlet ports 7a, 8a by pushing the other valve disks 7b, 8b are formed on at least one of the valve disks 7b, 8b so as to project from the inlet/outlet ports 7a, 8a. An annular projection 7e which is pressed to a synthetic resin valve seat 8e formed on the front surface of the other coupler 9B in tight contact therewith is so formed as to enclose the inlet/outlet port 7a.

Abstract: PURPOSE:To provide a spark arrestor in electrostatic spray coating capable of preventing spark from occurring between a material to be coated and a coater by surely detecting the abnormal access of the material to the coater grounded when applying high voltage to the material and performing electrostatic spray coating with the coater grounded. CONSTITUTION:After a coater to be grounded is installed in the insulated state, it is connected to an earth 12 through grounded circuits 11A, 11B. An abnormal current detector 13 for detecting abnormal current flowing in the grounded circuits 11A, 11B, and a controller 15 to lower the current and voltage fed to the material to be coated W based on the detected-signal are provided.

Abstract: PURPOSE:To surely prevent the formation of thin films on the liquid surface of a water-base coating material by constituting a coating material tank of an air-tight tank and connecting a supply tube for compressed air which imparts inner pressure to prevent the vaporization of water from the water-base coating material. CONSTITUTION:To the coating material tank 1, a supply tube 4 for the coating material to send the water-base coating material from the tank 1 to each coater 3 under pressure by a pump 2, a return tube 5 for an excess coating material which is not sprayed by the coater 3, and a supply tube 7 for compressed air connected to a supply source of compressed air are connected. When the tank 1 is charged with the specified amt. of water-base coating material, the tank 1 is hermetically sealed to make the air-tight state, for which compressed air is introduced through the supply tube 7 for compressed air to obtain about 1-4kg/cm internal pressure of the tank 1. Thereby, vaporization of water in the water-base coating material reserved in the tank 1 is prevented. Thus, the formation of thin films on the liquid surface of the coating material, which causes ruggedness in a coating film, can be surely prevented.
