施例についてその構成を説明する。Electro-coating has been adopted, but although it may be possible to use non-conductive organic solvent-based paint, when using conductive water-based paint, the entire paint supply system must be closed in order to obtain an electrostatic effect. It has the disadvantage that it must be insulated, and it also contains the danger of high voltage being applied to the main paint tank in the paint mixing room. By adopting the structure described in the claims of the present invention, the paint supply system that requires insulation can be shortened regardless of whether water-based paint is used, and high voltage is completely removed from the paint main tank in the paint mixing room. No voltage is applied, which improves safety. 5 The configuration of the illustrated embodiment will be explained below.

中継タンク4に戻るように構成されている。In the drawing, a coating gun 2 is arranged in a coating booth 1 and is equipped to apply electrostatic coating to an object 3 to be coated.
This paint gun 2 is constantly supplied with water-based paint from a relay tank 4 outside the paint booth 1 via a paint pressure pump 5 and a feed hose 6. Also, surplus paint during operation is configured to return to the relay tank 4 through a return hose T.

。The paint supply pipe 12 is constantly supplied with water-based paint from the paint main tank 15 in the paint mixing chamber 14 by the paint pressure pump 16, and when the discharge port 13 is closed, the paint is sent to the return pipe. It can return to the paint main tank 15 via IT.
上述の吐出口13には、開閉バルブ18が設けられてお

御により開閉される。The above-mentioned discharge port 13 is provided with an on-off valve 18, and this on-off valve 18 is opened and closed under the control of an on-off control mechanism 19.

いかなる機構のものでもよい。This opening/closing control mechanism 19 controls the application of high voltage when the object 3 to be coated passes in front of the coating gun 2 in the coating booth 1 and the high voltage generator 9 is activated to apply a high voltage to the coating gun 2. In response to the signal, the on-off valve 18 is closed, and when the object 3 to be coated has finished passing in front of the coating gun 2 and no high voltage is applied, the on-off valve 18 is closed in response to the no-application signal. If it opens and responds so that the water-based paint sent from the paint supply pipe 12 is discharged and supplied from the discharge port 13 through the paint supply port 11 and into the relay tank 4,
It may be of any mechanism.
上記構成の本発明装置では、導電性の水性塗料の供給系

塗料供給口11に対し、空間的に隔離されているので、
塗料主タンク15から前記吐出口13に至る第一の系と

的に全く絶縁された二つの系に区分されて構成されてお
り、吐出口13から水性塗料が連続して中継タンク4に
供給されているときにのみ、二つの系は電気的に導通状
態とされるに過ぎない。In the apparatus of the present invention having the above configuration, the conductive water-based paint supply system has the discharge port 13 of the paint supply pipe 12 spatially isolated from the paint supply port 11 of the relay tank 4.
The system is divided into two electrically insulated systems: a first system from the main paint tank 15 to the discharge port 13, and a second system from the relay tank 4 to the paint gun 2. The two systems are electrically connected only when the water-based paint is continuously supplied to the relay tank 4 from the discharge port 13.
したがつて、塗装ガン2に高電圧が印加されているとき

塗料主タンク15から吐出口13に至る第一の系には、
該高電圧は全く印加されないものであり、同時にこの第
一の系がアースと絶縁されていなくとも、塗装ガン2の
静電効果には全く影響を与えない。Therefore, when a high voltage is applied to the coating gun 2, if the discharge of water-based paint from the discharge port 13 is interrupted,
The first system from the paint main tank 15 to the discharge port 13 includes:
The high voltage is not applied at all and at the same time has no effect on the electrostatic effect of the paint gun 2, even though this first system is not insulated from earth.

ことにより絶縁を要する区間を著しく短かくしうる効果
がある。Since the present invention has the above-mentioned configuration and function, the paint supply system that must be insulated from the ground in order to produce an electrostatic effect can be limited to the system from the relay tank to the paint gun, and By arranging the tank close to the coating gun, the area requiring insulation can be significantly shortened.

ある。In addition, the opening/closing control mechanism of the opening/closing valve allows water-based paint to be supplied from the main paint tank to the relay tank only when high voltage is not applied to the painting gun, and when high voltage is being applied to the painting gun, the opening/closing valve By closing, it is possible to completely insulate the space between the discharge port and the relay tank by using the space as an insulator, which has the effect of completely eliminating the risk of high voltage being applied to the main paint tank side. be.
