Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、塗装機の塗料噴霧方向に向かって並行に突出
する複数本のコロナピンが、塗装機の外周を囲繞する金
属環に沿って所定間隔で配された静電塗装用放電極に関
する。[Detailed Description of the Invention] [Industrial field of application] According to the present invention, a plurality of corona pins projecting in parallel in the paint spraying direction of a coating machine are provided along a metal ring surrounding the outer periphery of the coating machine. The present invention relates to a discharge electrode for electrostatic coating arranged at intervals.
静電塗装は、塗装機から噴霧する塗料粒子に、放電極か
ら発生する多量のマイナスイオンを付着帯電させ、更に
放電極と被塗物との間に形成した直流電界の力により、
その塗料粒子を効率良く被塗物に吸引吸着させるもので
ある。In electrostatic coating, a large amount of negative ions generated from the discharge electrode are attached and charged to the coating particles sprayed from the coating machine, and by the force of the DC electric field formed between the discharge electrode and the object to be coated,
The paint particles are efficiently sucked and adsorbed on the object to be coated.
ところで、静電塗装の方式には、放電極と被塗物との間
に形成される電界内に噴霧した塗料粒子に、放電極から
発するマイナスイオンを付着させるグリッド式と、高電
圧を印加した回転カップから塗料を噴霧する塗装機と被
塗物との間に直接電界を形成し、遠心力と静電気の霧化
作用によって塗料の微粒化荷電を行う遠心力−静電霧化
式とがある。By the way, in the electrostatic coating method, a grid type in which negative ions emitted from the discharge electrode are attached to the paint particles sprayed in the electric field formed between the discharge electrode and the object to be coated, and a high voltage is applied. There is a centrifugal force-electrostatic atomization type in which an electric field is directly formed between a coating machine that sprays paint from a rotating cup and an object to be coated, and the atomization charge of the paint is generated by the atomization action of centrifugal force and static electricity. .
また、グリッド式には、被塗物との間に電界を形成する
放電極と、その電界内に向かって塗料を噴霧する塗装機
とが互いに切り離して別々に設けられた方式と、放電極
を塗装機の外周に直接取り付けて両者が一体化された方
式とがある。In addition, in the grid type, a discharge electrode that forms an electric field between the object to be coated and a coating machine that sprays paint toward the electric field are provided separately from each other and a discharge electrode. There is a method in which both are integrated by directly attaching to the outer periphery of the coating machine.
そして、後者の方式は、例えば、特公昭35-7683号公報
に記載されたように、複数本のコロナピンが、塗装機の
外周を囲繞する金属環に沿って所定間隔で取り付けら
れ、塗装機から噴霧される塗料粒子が、その周囲を囲む
ように配した各コロナピンから発せられるマイナスイオ
ンを受けて直ちに帯電されるので、前者の方式よりも塗
料粒子の帯電率が良いとされていた。Then, the latter method is, for example, as described in Japanese Patent Publication No. 35-7683, a plurality of corona pins are attached at predetermined intervals along a metal ring surrounding the outer periphery of the coating machine, Since the sprayed paint particles are immediately charged by receiving negative ions emitted from each corona pin arranged so as to surround them, it is said that the charge ratio of the paint particles is better than that of the former method.
しかし、この方式も、回転カップで塗料の微粒化と荷電
を同時に行う遠心力−静電霧化式に比較すれば、被塗物
に対する塗料粒子の塗着効率が劣っていた。However, this system is also inferior in the coating efficiency of the coating particles to the object to be coated, as compared with the centrifugal force-electrostatic atomization system in which the coating cup is atomized and charged simultaneously by the rotating cup.
このため、現在の静電塗装は、遠心力−静電霧化式が主
流を占めている。Therefore, the centrifugal force-electrostatic atomization method is predominant in the current electrostatic coating.
しかしながら、遠心力−静電霧化式は、回転カップを有
する塗装機にDC-80〜120KV程度の高電圧が印加されるか
ら、塗装作業者の電撃事故や、塗装機と被塗物が異常接
近して生ずる火花放電を防止するために、高電圧発生装
置に高価な安全スイッチ等を設けなければならず、その
設備費が著しく嵩んでいた。However, in the centrifugal force-electrostatic atomization type, a high voltage of about DC-80 to 120KV is applied to a coating machine with a rotating cup, so a coating worker's electric shock or the coating machine and the object to be coated are abnormal. In order to prevent the spark discharge that occurs in the vicinity, it is necessary to provide an expensive safety switch or the like in the high voltage generator, and the equipment cost thereof is significantly increased.
また、近時は、世界的な環境保全運動が高まる中、塗装
業界においても、公害防止と省資源のため水系塗料への
移行が推奨されているが、導電性のある水系塗料を高電
圧が印加された塗装機に供給する場合は、その塗料供給
系を絶縁しなければならないという面倒がある。In addition, in recent years, as the global environmental conservation movement has increased, the coating industry is also recommended to shift to water-based paints to prevent pollution and save resources. When supplying the applied coating machine, the coating supply system must be insulated.
殊に、自動車塗装のように、30〜60色もの多色塗装を行
う場合は、その塗料供給系すべてに絶縁対策を施さなけ
ればならないが、現実には不可能であるとさえ云われて
いる。In particular, when painting 30 to 60 colors, such as automobile painting, it is necessary to take insulation measures for all the paint supply systems, but it is said that this is not possible in reality. .
なお、この事情は、遠心力−静電霧化式の静電塗装に限
らず、特公昭35-7683号公報に記載されたように、塗装
機とその外周に取り付ける放電極とを一体化したグリッ
ド式の静電塗装においても同様である。Incidentally, this situation is not limited to centrifugal force-electrostatic atomization type electrostatic coating, but as described in JP-B-35-7683, a coating machine and a discharge electrode attached to the outer periphery thereof are integrated. The same applies to grid type electrostatic coating.
一方、塗装機の周囲を囲む金属環等の環状導体に沿って
複数本のコロナピンを所定間隔で配したものにあって
は、塗装機から噴霧された塗料がその環状導体やコロナ
ピンに付着して汚れ、これが粗い塗料粒子となって二次
的に飛び出し、被塗物に付着して塗装不良を生ずるとい
う問題があった。On the other hand, in the case where a plurality of corona pins are arranged at predetermined intervals along an annular conductor such as a metal ring surrounding the coater, the paint sprayed from the coater adheres to the annular conductor and corona pins. There is a problem that stains, which become coarse paint particles and fly out secondarily, adhere to the object to be coated and cause defective coating.
そこで、コロナピンの先端部のみを露出させ、その他の
導体部分すなわち当該コロナピンや環状導体を絶縁材で
被覆することにより、これらに塗料を付着させないよう
にしたものも提案されている（特開昭62-277171号公
報，特開昭63-258665号公報参照）。Therefore, there is also proposed a method in which only the tip of the corona pin is exposed and the other conductor portions, that is, the corona pin and the annular conductor are covered with an insulating material to prevent the coating material from adhering to them (JP-A-62-62) -277171, JP-A-63-258665).
しかし、この場合もコロナピンにはDC-80〜120kV程度の
高電圧が印加されるから、やはり、被塗物等のアース物
体が異常接近したときに生ずる火花放電や電撃事故を防
止することはできなかった。However, in this case as well, a high voltage of about DC-80 to 120 kV is applied to the corona pin, so it is still impossible to prevent spark discharge or electric shock accident that occurs when an earth object such as an object to be coated comes into abnormal proximity. There wasn't.
また、塗装機の周囲に配された各コロナピンは環状導体
を介して互いに電気的に接続されるだけでなく高電圧ケ
ーブルにも直接接続されているので、高電圧の供給が停
止された後であっても、一本のコロナピンにアース物体
が近づくと、全てのコロナピン，環状導体及び高電圧ケ
ーブルに蓄積された電荷が瞬時にそのアース物体に向か
って流れるので、火花放電や電撃事項を起こすおそれが
ある。In addition, since each corona pin arranged around the coating machine is not only electrically connected to each other via the annular conductor but also directly connected to the high voltage cable, after the high voltage supply is stopped, Even if there is one corona pin, the electric charge accumulated in all corona pins, ring conductors, and high-voltage cables instantly flows toward the grounded object when a grounded object approaches, which may cause spark discharge or electric shock. There is.

率良く荷電できるようにして、塗料供給系を絶縁する面
倒をなくすると同時に、電撃事故や火花放電の危険もな
くせるようにすることを技術的課題としている。Therefore, in order to promote the use of non-polluting water-based paint, the present invention has improved the conventional grid type and efficiently applied the paint particles sprayed from the paint machine at the discharge electrode without applying a high voltage to the paint machine. The technical task is to enable charging and eliminate the trouble of insulating the paint supply system, and at the same time eliminate the danger of electric shock and spark discharge.

前記金属環に接続されたことを特徴とする。In order to solve this problem, the present invention has a plurality of corona pins that project in parallel toward the paint spray direction of the coating machine, arranged at predetermined intervals along a metal ring surrounding the outer periphery of the coating machine. In an electrostatic coating discharge electrode in which a metal ring is connected to a high-voltage cable and is attached to a coating machine in an electrically insulated state, each corona pin has an insulating ring-shaped case that accommodates the metal ring. It is attached to the tip of each insulating case that is provided at a predetermined interval along with, and is connected to the metal ring through a high resistor provided in each insulating case.

また、高電圧ケーブルに接続される金属環が、塗装機に
対して電気的絶縁状態で取り付けられているから、塗装
機へ水系塗料を供給する塗料供給系に面倒な絶縁対策を
施す必要がない。In addition, the metal ring connected to the high-voltage cable is installed in an electrically insulated state with respect to the coating machine, so there is no need to take troublesome insulation measures for the coating supply system that supplies water-based coating to the coating machine. .

れがない。Furthermore, each corona pin is attached to the tip of the insulating case that is provided at a predetermined interval along the metal ring, and is connected to the metal ring through the high resistor provided in the insulating case. Even if a human body or a grounded object such as an object to be approached approaches this, there is no risk of spark discharge or electric shock accident because a voltage drop occurs in the high resistor while supplying a high voltage.
Further, after the supply of the high voltage is stopped, at most, only the electric charge accumulated in one corona pin is discharged to the ground object, so that there is no possibility of electric shock or spark discharge.
