静電塗装装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrostatic coating device that ensures the safety of painted confectionery by discharging electrically charged paint from a paint tank to the outside of the painting booth.
一般に、塗装ブース内には高電圧を印加しつつ塗料を静
電霧化する塗装機を設け、該塗装機は塗料ホースを介し

被塗物に向は噴霧するようにした静電塗装装置が知られ
ている。Generally, a paint booth is equipped with a paint machine that electrostatically atomizes paint while applying a high voltage, and the paint machine is connected to a paint tank via a paint hose, and the paint tank is placed on an insulated stand. However, an electrostatic coating device is known in which a conductive paint such as a water-based paint or a metallic paint is stored in the paint tank, and the conductive paint is sprayed from a coating machine onto the object to be coated. .
しかし、このように塗料として導電性塗料を使用し九場
合、塗装機に高電圧（例えば−９０ｋＶ）を印加すると
、この高電圧は塗料ホース内に充満している塗料を伝わ
って塗料タンクまたはその内部の塗料を塗装機とほぼ同
電位にしてしまう現象を起す。このため、塗料タンクが
高電位となって塗装作業中にま九は作業停止後に該１１
１科タンクに人手が接触すると電撃を受けたり、また塗
料タンクやその内部の塗料にス・臂−りが発生する程度
までの電荷量が蓄えられると、このスノ４−りのために
溶剤蒸気に着火して爆発や火災を起す危険性がある。。However, when a conductive paint is used as the paint in this way, if a high voltage (for example -90kV) is applied to the paint sprayer, this high voltage will be transmitted through the paint filling the paint hose to the paint tank or the paint tank. This causes the paint inside to have almost the same potential as the paint sprayer. For this reason, the paint tank became high potential and during painting work, the paint tank was stopped and the 11
If a person comes into contact with the tank, he or she will receive an electric shock, or if the paint tank or the paint inside it accumulates enough charge to cause splatters, solvent vapor will be released due to this sludge. There is a risk of ignition, causing an explosion or fire. .

地されたアース棒を塗料タンクに接触させ、該塗料タン
クに蓄えられた電荷を放電するようにしていた。In order to eliminate the above-mentioned dangers, conventionally, after painting with conductive paint, a ground rod whose tip is grounded outside the paint booth is brought into contact with the paint tank, and the electric charge stored in the paint tank is removed. was designed to discharge.
しかし、このようなアース棒を用いる方法にあっては、
その都度人手によってアース棒を塗料タンクに接触させ
なくてはならず一非常に煩わしいという欠点があった。However, with this method of using a grounding rod,
The disadvantage is that the grounding rod must be brought into contact with the paint tank each time by hand, which is extremely troublesome.
また、塗料タンクに塗料が付着してい走り、アース棒が
発錆し、または塗料が付着して確実に放電を行なうこと
ができないという欠点があった。In addition, there are also disadvantages in that paint adheres to the paint tank, causes rust on the grounding rod, or prevents reliable discharge due to paint adhesion.
一方、塗料タンクに導電性塗料と、例えばソリッド塗料
のような非導電性塗料とをある周期で交互に貯え、複数
種類の塗料を使い分ける塗装方式がある。このような方

塗料を使用している場合でも塗装機と被塗物との間の電
界中に塗料タンクがあると、該塗料夕／りおよび塗料に
電荷が蓄えられてしまう恐れがあうた。On the other hand, there is a coating method in which a conductive paint and a non-conductive paint such as a solid paint are alternately stored in a paint tank at a certain period, and multiple types of paint are selectively used. Even in this type of system, when using conductive paint, not only must the electric charge stored in the paint tank be discharged each time using a grounding rod, but also when using non-conductive paint. Even if the paint tank is present in the electric field between the paint sprayer and the object to be coated, there is a risk that electric charge will be stored in the paint sludge and the paint.
本発明はこのような従来技術による静電塗装装置の欠点

うにした静電塗装装置を提供するものである。The present invention improves the shortcomings of the electrostatic coating equipment according to the prior art, and installs a high voltage switch located outside the coating booth in the middle of the high voltage cable for discharging the charges accumulated in the paint tank. The present invention provides an electrostatic coating device in which the safety of coating work is ensured by opening and closing the high voltage switch.

In the case where a metal plate is attached to the insulating stand 7 and the paint tank 8 is made of gold, the electric charge stored in the paint pump 9 is transferred to a high voltage via the high voltage cable 20, the metal plate, and the paint tank 8. It may be configured to discharge from the voltage cable 16. However, when conductive paint is stored in the paint tank 8, the paint jink 8 and the paint Ig 9 are brought to substantially the same potential via the paint hose 11, so the high voltage cable 20 is unnecessary.

Dispense by flying towards the object to be coated. At this time, the high voltage applied to the paint sprayer 2 is applied to the paint hose 14 and the three-way switching valve 13 because the electrical resistance value of the paint is low (in the case of metallic paint, the electrical resistance value is 0.3 or less). , flows into the paint tank 8 via the paint hose 15, and has almost the same potential as the paint machine 2. Also, the paint bongoo 9 is also a paint hose tt.
, 't2, the potential becomes the same as that of the paint tank 8. However, since the high voltage switch 17 is open, the paint tank 8 remains in the state where the high voltage is applied, so that the m-loading operation is possible.

After stopping the paint 4 and 9, when the selection switch 18 is switched to the contact 18B side, the excitation coil t7A of the high voltage switch 17 is extinguished, returns to the contact 17B position and is closed, and the paint tank 8 is closed. Then, the electroconductive paint is charged and the psychic charge is discharged. At the same time, the electric charge charged on the paint sensor 9 is also discharged via the high voltage cable 20 or the paint hose 11. Therefore, even if the paint tank 8 is touched after it is completely grounded, the user will not receive an electric shock. Mae,
Since there is no risk of explosion or fire, cleaning work and color changing work can be carried out safely.
