Description

本発明は、静電噴霧塗装において使用される荷電用電源の供給と噴霧化用空気供給において、それぞれの供給源から静電塗装スプレーガンに供給するための接続供給手段及びその供給手段を備えた静電スプレーガンに関する。 The present invention includes a connection supply means for supplying power to an electrostatic coating spray gun from each supply source and a supply means for supplying a power source for charging and an atomizing air supply used in electrostatic spray coating. It relates to an electrostatic spray gun.

静電塗装装置において一般的な装置は、噴霧化装置と高電圧静電気により電界形成と塗料への荷電を行う荷電装置を有する静電塗装ガン、該静電塗装ガンに塗料を供給する装置、高電圧荷電のために必要な電力を供給する電源装置、及びこれらを接続する塗料ホース・空気ホース・電源ケーブル等の接続供給手段より構成されている。これらの構成は塗装手段の違いにより異なり、必要のないものも有るがほとんどの場合に使用されており、塗装機(スプレーガン)には前記塗料ホース、空気ホース、電源ケーブルの3本のホース又はケーブルが接続されている。 A general apparatus in an electrostatic coating apparatus includes an atomizing apparatus, an electrostatic coating gun having a charging device for forming an electric field and charging a paint by high-voltage static electricity, an apparatus for supplying the electrostatic coating gun with a paint, The power supply device supplies power necessary for voltage charging, and connection supply means such as a paint hose, an air hose, and a power cable for connecting them. These configurations differ depending on the coating means, and some of them are not necessary, but are used in most cases. The paint hose (spray gun) has three paint hose, air hose, three hoses of power cable or The cable is connected.

汎用的に多く用いられる静電塗装ガンにはエア霧化方式があり、特に作業者の手によって操作される手持ち式の静電塗装ガンは、このエア静電塗装ガンが圧倒的に多く使用されている。この種のエア静電塗装ガンに高電圧を荷電する方式としては、近年高周波低電圧を電源ケーブルで供給し、静電ガンの内部において変圧器及び倍電圧整流回路等により所定の高電圧に昇圧して荷電する方法が用いられるようになってきた。したがって高電圧そのものを電源ケーブルで供給する従来の方式に比べ、ケーブルの耐電圧に対する特別な構成の必要性がなくなっている。 There is an air atomization method for electrostatic coating guns that are widely used for general purposes. Especially, hand-held electrostatic coating guns that are operated by the hands of operators are overwhelmingly used. ing. As a method of charging a high voltage to this type of electrostatic electrostatic gun, in recent years, a high frequency and low voltage has been supplied by a power cable, and the voltage is boosted to a predetermined high voltage by a transformer and a voltage doubler rectifier circuit inside the electrostatic gun. Thus, charging methods have been used. Therefore, the necessity of a special configuration for the withstand voltage of the cable is eliminated as compared with the conventional method of supplying the high voltage itself with the power cable.

また静電塗装ガンを塗装場で操作するにあたり、高電圧電源の荷電制御の他、安全性の見地からアース線、荷電電流の検知用回路、異常時の検出・遮断等の回路用電線が必要となり、前記電源ケーブルには複数の電線が必要となっている。特開平10−128170号公報は、その一例で電源(制御装置)と静電塗装ガンを結ぶ回路が示されている。これらに用いるケーブルは既存の複数芯線で構成されたケーブルが用いられるのが一般的である。 Also, when operating the electrostatic painting gun at the painting site, in addition to charge control of the high-voltage power supply, grounding wires, circuits for detecting the charged current, and electric wires for detecting and shutting off when there is an abnormality are necessary from the viewpoint of safety Thus, a plurality of electric wires are required for the power cable. Japanese Patent Application Laid-Open No. 10-128170 discloses a circuit connecting a power source (control device) and an electrostatic coating gun as an example. The cable used for these is generally an existing cable composed of a plurality of core wires.

一方塗料ホース、エアホースはそれぞれ単独で、塗料供給装置及び空気源より静電塗装ガンに供給される方式となっている。したがって前記の電源ケーブルを加えた3本が静電ガンに接続され、扱いを考慮して部分的に束ねられた状態で使用されている。この状態で使用しての問題はそれぞれのホースもしくはケーブルの汚れである。塗装域ではこれらのホースやケーブルへの塗料等の付着は避けがたく、汚れによる他への汚損、高電圧のリークによる危険性の増加等があり、定期的な清掃が必要となっている。
また各ホース、ケーブルを束ねた場合、操作中にいずれかのホース、ケーブルに負担が掛かり損傷の危険が増すこともあって、束ね方自体に配慮をし、定期的なチェックが必要でもあった。
On the other hand, the paint hose and the air hose are each independently supplied to the electrostatic paint gun from the paint supply device and the air source. Accordingly, the three power cables are added to the electrostatic gun and are used in a partially bundled state in consideration of handling. The problem with using in this state is the soiling of the respective hose or cable. In the painting area, it is unavoidable that paints or the like adhere to these hoses and cables, and there is an increase in danger due to contamination due to dirt, leakage due to high voltage, etc., and periodic cleaning is necessary.
In addition, when bundling each hose and cable, the burden on one of the hoses and cables may increase during operation, increasing the risk of damage. Considering the bundling method itself and periodic checks were also necessary. .

空気を必要とする装置に供給するためのエアホースに電線を併設し、一体化した技術は特定の技術として、例えば特開平4−29692号公報に示されるごとく、すでにいくつかの例が見られるが、高電圧を扱う静電塗装装置の分野では実用において適切な手段が示されていない。
特開平4−29692号公報 特開2001−50438号公報 実開平5−47679号公報 特開平10−128170号公報
As an example of a specific technique for integrating an electric wire with an air hose for supplying air to a device that requires air, as shown in, for example, Japanese Patent Laid-Open No. 4-29692, several examples have already been seen. In the field of electrostatic coating apparatuses that handle high voltages, no means suitable for practical use has been shown.

静電塗装におけるスプレーガンには、塗料ホースの他、エアホースと電源ケーブルが必要であり、操作する上での不都合さに問題があった。近年塗装ガンの内部昇圧による方式により電源ケーブルは低電圧化され、細く軽くなってきているが、塗装現場でのホース、コード類の汚れに対する清掃処理等の問題もあり、洗浄性、取扱い性の改善が望まれている。 The spray gun in electrostatic coating requires an air hose and a power cable in addition to a paint hose, which has a problem in inconvenience in operation. In recent years, the power supply cable has been reduced in voltage and reduced in thickness due to the internal boosting method of the paint gun, but there are also problems such as cleaning treatment for dirt on hoses and cords at the painting site, and it is easy to clean and handle. Improvement is desired.

塗料と圧縮エアと静電荷電用電源をそれぞれ静電スプレーガンに供給して静電塗装を行う装置において、荷電電極を備え、外部より供給される低電圧電源を直流高電圧に昇圧する高電圧発生器を内蔵し、噴霧操作信号によって荷電電極への荷電が制御される静電スプレーガンに用いる電源ケーブルとして、複数の芯線をエアホースの周囲に配置して螺旋状に巻き、かつその周囲にシールド線で被覆した電源ケーブルを用いる。 A high voltage that boosts a low voltage power source supplied from the outside to a DC high voltage in a device that performs electrostatic coating by supplying paint, compressed air, and electrostatic charging power to an electrostatic spray gun. As a power cable for use with an electrostatic spray gun that has a built-in generator and the charge to the charging electrode is controlled by a spray operation signal, multiple core wires are placed around the air hose and spirally wound, and shielded around it Use a power cable covered with wire.

静電エアスプレーガンに供給空気接続口と電源及び制御ケーブルのコネクタソケットを備えた取付け台を設け、この取付け台の前記それぞれの供給空気接続口と電源及び制御ケーブルに嵌合して着脱可能に接続する空気供給端子と配電用プラグを備えた接続プラグを設けるとともに、この接続プラグと、電源及び空気源とを接続するケーブルにはエアチューブの周囲に複数の金属導線と補強糸で撚り合わせ、さらにシールド線と外被で構成したエアホース一体形の電源ケーブルを用いた。 An electrostatic air spray gun is provided with a mounting base with a supply air connection port and a connector socket for the power supply and control cable, and can be attached to and removed from the mounting air supply port, power supply and control cable of the mounting base. While providing a connection plug with an air supply terminal to be connected and a power distribution plug, the cable connecting the connection plug, the power source and the air source is twisted with a plurality of metal wires and reinforcing yarn around the air tube, Furthermore, an air hose integrated power cable composed of a shielded wire and a jacket was used.

また前記取付け台と接続プラグは装着後、確実に固定される締結手段を用いて使用時の外れ等によるトラブルを防止している。さらに前記接続プラグは配電用プラグと供給空気端子を装着した端板と端子カバーで構成し、該端子カバーと前記電源ケーブルとを緊締して実用的に装着の容易化が図れる。
エアホースと接続プラグの接続と、接続プラグを静電ガンの取付け台に接続する容易化のために、エアホースを端板に挿入し、そのエアホースの内径部に緊密に嵌挿した供給空気端子の先端外周にシール環を介装した。
Further, the mounting base and the connection plug are used to prevent troubles caused by detachment during use by using fastening means that is securely fixed after mounting. Further, the connection plug is constituted by an end plate and a terminal cover on which a power distribution plug, a supply air terminal is mounted, and the terminal cover and the power cable are tightened to facilitate practical mounting.
For easy connection between the air hose and the connection plug and the connection plug to the electrostatic gun mounting base, insert the air hose into the end plate, and insert the tip of the supply air terminal into the inner diameter of the air hose. A seal ring was interposed on the outer periphery.

静電塗装用のスプレーガンは、通常のスプレーガンに比較し、高電圧の発生手段を必要とし、高電圧荷電に対する絶縁等のために小形化が難しく、さらに前記のごとくホース類が3本あるために取り扱いにくく、かつその質量で重いために、作業者にとって取扱い上で大きな問題であった。またこれらのホースは汚れやすく、定期的な清掃を必要とし、塗装作業全体を考えた場合に、作業能率の低下、清掃に要する洗浄液の無駄があった。 The spray gun for electrostatic painting requires a means for generating a high voltage as compared with a normal spray gun, and it is difficult to reduce the size due to insulation against high voltage charge, and there are three hoses as described above. Therefore, it is difficult to handle and heavy due to its mass, which is a big problem in handling for the operator. Further, these hoses are easily soiled and require regular cleaning. When considering the entire painting operation, the work efficiency is lowered and the cleaning liquid required for cleaning is wasted.

本発明の実施により静電スプレーガンに取り付くエアホースと電源コードが一体になり、操作性はもちろんエアホースの清掃がなくなり、塗装作業以外の清掃作業が削減されて、全体の作業能率が向上する。
さらに清掃作業に使用する洗浄液、通常は洗浄用のシンナー使用量が大幅に削減でき、資源の節約、揮発性有機化合物の排出量の削減にもなり、結果的に環境の保護につなげることができる。
By implementing the present invention, the air hose attached to the electrostatic spray gun and the power cord are integrated, and the air hose is not cleaned as well as the operability, and the cleaning work other than the painting work is reduced, and the overall work efficiency is improved.
In addition, the amount of cleaning liquid used for cleaning work, usually thinner for cleaning, can be greatly reduced, saving resources and reducing emissions of volatile organic compounds, resulting in environmental protection. .

中心のエアチューブの周囲に複数の導線を補強糸と交互に配置し、螺旋状に巻きつけているためエアチューブ径にかかわらず極端な曲げに対しても柔軟性が損なわれず電気的接続が維持される。さらに外側のシールド線で電気的ノイズからも保護される。
また本発明によれば静電塗装ガンの取付け台に空気接続口とコネクタソケットを配してこれらと嵌合する接続プラグを設けることで簡単かつ確実にそれぞれを接続することができ、ケーブルの着脱、静電ガンの交換等の作業が容易になる。
Multiple conductors are alternately arranged around the central air tube with reinforcing threads and wound spirally, so that the electrical connection is maintained without losing flexibility even for extreme bending regardless of the air tube diameter. Is done. In addition, the outer shield wire protects against electrical noise.
Further, according to the present invention, the air connection port and the connector socket are arranged on the mounting base of the electrostatic coating gun, and the connection plugs to be fitted to these are provided so that each can be connected easily and reliably, and the cable can be attached and detached. This makes it easy to replace the electrostatic gun.

エアチューブはプラグの端板に挿入され供給端子によって緊密に固定されており、この供給端子の外周に設けたシール環によって静電ガンの取付け台に差し込むだけで配管することができ、取扱いが容易となる。
The air tube is inserted into the end plate of the plug and is tightly fixed by the supply terminal, and it can be piped by simply inserting it into the mounting base of the electrostatic gun with a seal ring provided on the outer periphery of the supply terminal, making it easy to handle It becomes.

本発明の実施例を図面に基づいて詳細に説明する。図4は静電塗装ガンの断面構成と装置全体の概略構成を表している。静電塗装ガン1は先端部に霧化装置2が配置され、この例では空気キャップ3により塗料ノズル4から噴出する塗料を圧縮エアで噴霧化するエア霧化方式のスプレーガンが示されている。噴霧塗料は塗料供給装置Pから塗料ホース30によって供給され、前記塗料ノズル4から噴出する。 Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 4 shows a sectional configuration of the electrostatic coating gun and a schematic configuration of the entire apparatus. The electrostatic coating gun 1 is provided with an atomizing device 2 at the tip, and in this example, an air atomizing type spray gun is shown in which the paint ejected from the paint nozzle 4 by the air cap 3 is atomized with compressed air. . The spray paint is supplied from the paint supply device P by the paint hose 30 and ejected from the paint nozzle 4.

高電圧を荷電する電極6は、本例の場合霧化装置の中心部に配置されているが、静電塗装ガンの形態によって、その他の形態、位置に配置されることがある。高電圧は、握り部7に設けた取付け台8のソケット9より静電塗装ガン1内に送り込まれた電源が高電圧発生器10に送り込まれ、ここで一般的には50から80キロボルトに昇圧され、前記電極6より放電して被塗装物への電界を形成し、かつ噴霧塗料を電気的に帯電させる。 In the case of this example, the electrode 6 that charges a high voltage is disposed at the center of the atomizer, but may be disposed in other forms and positions depending on the form of the electrostatic coating gun. The high voltage is supplied from the socket 9 of the mounting base 8 provided in the grip 7 to the electrostatic coating gun 1 to the high voltage generator 10 where it is generally boosted to 50 to 80 kilovolts. Then, the electrode 6 is discharged to form an electric field to the object to be coated, and the spray paint is electrically charged.

静電塗装ガン1には高周波低電圧電源Eから通常十数ボルト乃至数十ボルトの低電圧が電源ケーブル20によって前記静電塗装ガン1に供給されるため、電源の供給のみであればケーブル自体に特別な耐電圧構造の必要なく汎用的なケーブルで可能となる。さらに、圧縮空気によって噴霧化を行う本例の場合、コンプレッサ等の空気供給源Aからエアホースによって圧縮空気を供給するが、本例の場合、前記の電源ケーブル20を後述する通りエアホースと同軸に一体構成させたことで、1本で示されている。 The electrostatic coating gun 1 is normally supplied with a low voltage of several tens to several tens of volts from the high-frequency low-voltage power source E to the electrostatic coating gun 1 through the power cable 20. In addition, a general-purpose cable can be used without the need for a special withstand voltage structure. Further, in the case of this example in which atomization is performed by compressed air, compressed air is supplied from an air supply source A such as a compressor by an air hose. In this example, the power cable 20 is integrated with the air hose as described later. This is shown as a single line.

高電圧発生器10は詳細が図示されていないが低電圧電気を数千ボルトに昇圧させる変圧器、さらに整流と昇圧を行う倍電圧整流回路、高抵抗体を含み、前記した高電圧直流電気として出力する構造になっている。これらの構成は一例として、特開平8−302456号公報に詳細が示されている高電圧発生装置等をあげることができる。 Although not shown in detail, the high-voltage generator 10 includes a transformer that boosts low-voltage electricity to several thousand volts, a voltage doubler rectifier circuit that rectifies and boosts, and a high-resistance element. It has a structure to output. As an example of such a configuration, a high voltage generator described in detail in JP-A-8-302456 can be given.

前記取付け台8のソケット9は、複数本の電線が図示されているが、このうちの2本乃至3本がアース線を含め電源供給に使用されている。その他必要により荷電制御、電流検出等に使用されている。取付け台8は握り部7に固定され、噴霧化用空気を前記霧化装置2に供給するエア通路11の入り口となる空気接続口12が形成されている。 A plurality of electric wires are illustrated in the socket 9 of the mounting base 8, and two or three of them are used for power supply including a ground wire. In addition, it is used for charge control, current detection, etc. if necessary. The mounting base 8 is fixed to the grip 7 and is formed with an air connection port 12 serving as an inlet of an air passage 11 for supplying atomizing air to the atomizing device 2.


静電塗装ガン1の取付け台8側と電源ケーブル20側の接続の方法は、図1に取付け前の状態を示すように、電源と霧化用エアを供給する側の接続プラグ13は、端板14に配電用プラグ15、供給空気端子16が取付けられ端子カバー17とともに前記握り部7の取付け台8に固定される。供給空気端子16は、端板14の取付け穴22に差し込まれた空気チューブ21の出口側より嵌挿することによって固定される。さらに供給空気端子16は突き出た端部外周に環状シール23を設け、前記取付け板8の空気接続口12に差し込むことで漏洩を防止した接続ができるよう構成されている。前記、緊密に固定する手段としては、既存技術の範囲内で考えられる他の締結接続手段を用いることもできる。

The connection method between the mounting base 8 side of the electrostatic coating gun 1 and the power cable 20 side is as follows. As shown in FIG. The power distribution plug 15 and the supply air terminal 16 are attached to the plate 14 and fixed together with the terminal cover 17 to the mounting base 8 of the grip portion 7. The supply air terminal 16 is fixed by being inserted from the outlet side of the air tube 21 inserted into the mounting hole 22 of the end plate 14. Further, the supply air terminal 16 is provided with an annular seal 23 on the outer periphery of the protruding end, and is connected to the air connection port 12 of the mounting plate 8 so as to be connected to prevent leakage. As the means for tightly fixing, other fastening connection means conceivable within the scope of the existing technology can be used.

Further, a shield wire 26 made of a metal wire is coated on the outer periphery in a mesh shape, and the outermost periphery is covered with a protective coating 27.

These terminals are electrically connected to each other and inserted into the mounting base 8 of the electrostatic gun 1 for connection. The end plate 14 is fixed to the terminal cover 17 together with the power cable 20 to be securely fixed. Further, after being inserted and connected to the electrostatic gun, it is securely fixed by the screw 28.

空気チューブ21と各導線の接続方法は、前記のソケットとプラグによるコネクタを使用する他、静電ガン側の取付け台とケーブル側の端板に直接設けたそれぞれの端子をオスメスの嵌合手段、もしくは圧接手段によって簡単に接合できる方法が採られる。図3の事例は、電源ケーブルを取り付けたときにばね31の弾発力で電気的接続をさせた圧設の一例で、具体的嵌合もしくは圧接手段は必要に応じて公知の技術から選択される。 The connection method of the air tube 21 and each conductor is not only the use of the connector by the socket and the plug, but also the male and female fitting means provided on the electrostatic gun side mounting base and the cable side end plate. Or the method of joining simply by a press-contact means is taken. The example of FIG. 3 is an example of press-fitting in which electrical connection is made by the elastic force of the spring 31 when the power cable is attached, and the specific fitting or press-contact means is selected from known techniques as required. The
