However, since a high voltage is directly applied to the main body of the coating machine, a non-conductive coating which does not leak current from the coating path is applicable. In the case of a conductive paint such as a water-based paint, a current leaks through the paint, so that a voltage cannot be directly applied to the coating machine. As shown in FIG. An external electrode 32 to which a high voltage from 33 is applied is provided to perform electrostatic coating. This is called an external electrode system and is disclosed in, for example, Japanese Patent Application Laid-Open No. 61-78452. Further, in recent years, as shown in FIG. 4, an external electrode 42 to which a high voltage is applied from a high voltage generator 43 is provided around a coating machine main body 41, and a high voltage for charging is also directly provided on the coating machine main body 41. A voltage is applied to the external electrode 42 in the case of a conductive paint, and to the coating machine main body 41 in the case of a non-conductive paint. There are also methods of performing both types of electrostatic coating (for example, Japanese Patent Application Laid-Open No. 2-47174, Japanese Utility Model Application Laid-Open No. 2-47174).
No. 37765).

・非導電性塗料両用の静電塗装装置を提供することにあ
る。In the external electrode type electrostatic coating apparatus shown in FIG. 3, a ground wire 34 is attached to forcibly drop the main body of the coating machine to the ground potential.
Therefore, the main body of the coating machine is grounded by both the paint and the water-based cleaning agent filled in the feed tube 35 and the ground wire 34, and if the paint or the like is removed from the coating machine, the external electrode 3
Even if a high voltage is applied to 2, the main body of the coating machine can be kept at the ground potential by grounding with the ground wire 34. However, in the electrostatic coating apparatus for both conductive and non-conductive shown in FIG.
Since it is necessary to connect the charging high voltage generator 44 directly to the coating machine main body 41 so that a high voltage can be applied directly, the ground cannot be taken directly from the coating machine main body 41 (the grounding of FIG. 3). No equivalent to line 34 can be provided). Therefore, the conductive paint is applied to the external electrodes 42.
When the electrostatic coating is performed by using the paint, the coating machine main body 41 is grounded only by the conductive paint. Therefore, if a high voltage is applied to the external electrode 42 in a state where the conductive paint is not filled in the coating machine as in the case of the color change cleaning, the coating machine body 41 is electrically insulated.
A large amount of electric charge is accumulated in the coating machine main body 41. If the grounding body approaches the coating machine main body 41 at this time, a spark may be generated between the coating machine main body 41 and the grounding body. An object of the present invention is to provide an electrostatic coating apparatus for both conductive and non-conductive paints, which can maintain electrostatic safety.

Is on). Turning on the ground of the coating apparatus main body 13 by the grounding system 16 is performed by opening the valve 10 and the valve 11, filling the supply path of the conductive fluid with the conductive fluid, and closing the valve 11 when the filling is completed. In the case of coating with a non-conductive paint, a high voltage is directly applied to the coating apparatus main body 13 from the charging high voltage generator 7 and the grounding of the coating apparatus main body 13 by the grounding system 16 is turned off (the ground wire 17 is connected to the ground). Off state). The paint supply system 14 is also non-grounded by the non-conductive paint. Turning off the grounding of the coating apparatus body 13 by the grounding system 16 is performed by opening the valve 11 and the air valve 12 and purging the conductive fluid in the supply path of the conductive fluid by air. Since the grounding of the coating apparatus main body 13 by the grounding system 16 is performed by charging and purging with the conductive fluid, the switching can be quickly performed. The merit of using a conductive fluid to turn on and off the ground is
The mechanism is simple and secure. The painting machine is
Since a voltage of tens of thousands of volts is applied, the potential with the ground portion is very large. Generally, when turning on and off the ground using a mechanical method such as a switch, the interval between the switches is short and high voltage cannot be sufficiently insulated. In order to ensure sufficient grounding and insulation properties, the structure becomes large and complicated. However, in the method using a conductive fluid,
By filling the hose with fluid, the coating machine can be grounded, and high-voltage insulation can be ensured only by air purging the fluid. Further, since the voltage gradually decreases by using the length of the hose, various voltages can be easily handled by selecting the length of the hose.

Then, at the time of the next coating, the cleaning solvent is filled again. In the case of coating with a non-conductive paint, a high voltage is directly applied from the charging high voltage generator 7 to the coating apparatus body 13 and the grounding system 16 is applied.
The grounding of the coating apparatus main body 13 is turned off (the ground wire 20 is off). The paint supply system 14 is also non-grounded by the non-conductive paint. The grounding of the coating apparatus main body 13 by the grounding system 16 is performed by opening the air valve 19 and purging the aqueous cleaning solvent in the cleaning agent path by air. Since the switching of the ground can be performed using the cleaning path, there is no need to provide a special circuit for performing the switching of the ground, and the configuration and control of the coating machine are easy.
