〈産業上の利用分野〉
本発明は深溝の中で入口部に返りのあるものやタンク内
面等の塗装に対処しえる液体吹付方法およびその装置に
関するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Field of Application> The present invention relates to a liquid spraying method and apparatus that can be applied to deep grooves with curved inlets, the inner surface of tanks, and the like.
〈従来の技術〉
従来、エアースプレーで塗料を斜め前方に噴射するには
片角ガンがあるが、これは一方向のみの噴射で、且つ深
溝をもった被塗物等の返りの部分は塗装できない（例え
ば、実公昭３５−６７８号公報）。即ち、片角ガンは細
長く伸びた塗料ノズル先端の周囲に霧化用空気口を形成
し、噴射した塗料に高圧空気を噴射衝突させて霧化し、
更に側方より別の高圧空気流を噴射衝突させて斜め前方
に噴霧流を形成するものであり、主として管内面の塗装
に用いられている。<Conventional technology> Conventionally, a one-sided gun is used to spray paint diagonally forward using air spray, but this sprays only in one direction, and the curved parts of objects with deep grooves are not painted. It is not possible (for example, Japanese Utility Model Publication No. 35-678). In other words, the single-sided gun forms an atomizing air port around the elongated tip of the paint nozzle, and atomizes the sprayed paint by spraying high-pressure air against it.
Furthermore, another high-pressure air stream is jetted from the side and collides with the other to form a spray stream diagonally forward, and is mainly used for painting the inner surface of a pipe.
この場合、噴射方向は少なくとも横方向９０°より大き
く、前方へ向う噴霧流となる。即ち、塗料の開口は前方
へ向いており、これを外部気流により後方に向う成分を
持たせるとノズル開口面に噴射塗料が付着し汚損すると
共に、付着した塗料が被塗面に飛び塗面を汚損する。In this case, the spray direction is at least greater than 90° in the lateral direction, resulting in a forward spray flow. In other words, the paint opening faces forward, and if an external airflow causes a component to flow backward, the sprayed paint will adhere to the nozzle opening surface and stain it, and the adhered paint will fly onto the surface to be coated and cause the surface to be coated. defile.
又、エアースプレーガンとして先端が曲り、横方向もし
くは斜め前、後方向に噴霧される所謂、長着ガンがある
が、塗料通路の他に空気通路を形成させるため、構造が
複雑で、先端ノズル部の形状も大きくなってしまう、エ
アースプレー以外では、エアレススプレーとしてパイプ
先端に首曲り構造とし自由に噴射角度を変えられるスプ
レーガンが既に存在する。Additionally, there is a so-called long spray gun, which has a curved tip and sprays horizontally or diagonally forward or backward, but it has a complicated structure because it forms an air passage in addition to the paint passage, and the tip nozzle In addition to air sprays, which require large parts, there are already airless spray guns that have a bent neck structure at the tip of the pipe and can freely change the spray angle.
また、内面塗装は被塗物の形状により種々の装置が用い
られているが、一般には裏面となる塗装は吹付は塗装で
行なわれることが少ない。Furthermore, various apparatuses are used for inner surface coating depending on the shape of the object to be coated, but in general, spraying is rarely used to coat the back surface.
これは吹付けによるオーバースプレーミストが作業者側
にくることや、適切な塗装装置がなかったことによる０
通常、溝が奥で広くなっている被塗物の場合、工場塗装
において浸漬等の方法によって塗装されるが、これらの
塗装は少量塗装に不適で、且つ設置後の塗り替え、補修
等は不可能である。しかし、腐蝕、発錆等の条件はむし
ろ内面の方が悪く、確実な塗装の必要性がある。入口部
に返りのあるＣ形鋼は内面の大きさが５０〜１００ ＋
ｓ＋ｓ程度のものが多く、従来のスプレーガンでは塗装
不可能であった。This is due to the overspray mist from spraying coming towards the worker and the lack of appropriate painting equipment.
Normally, objects to be coated with grooves that are wider at the back are painted using methods such as dipping at the factory, but these coatings are unsuitable for small quantities and cannot be repainted or repaired after installation. It is. However, conditions such as corrosion and rust are worse on the inner surface, so reliable painting is necessary. C-shaped steel with a curved entrance has an inner surface size of 50 to 100 +
Many of them were about s+s, and could not be painted with conventional spray guns.
前述のようにエアースプレーガンでは霧化頭が溝内に入
らず、且つ入るように小さい構造のものが仮に製作でき
たとしても噴出口そのものも小さくなり、必要な塗料噴
出量が得られず。As mentioned above, with an air spray gun, the atomizing head does not fit into the groove, and even if one could be made with a structure small enough to do so, the nozzle itself would also be small and the required amount of paint would not be ejected.
また高粘度の塗料になると噴出不可能となる。Also, if the paint has a high viscosity, it will not be possible to spray it.
更に、エアレススプレーガンでは高圧塗料を噴射するた
め噴出量が多すぎ、塗料の垂れ等の問題が起こる。塗料
の垂れを少なくするためには極度に小さいノズル口を用
いることとなり、十分に濾過した塗料でも詰りか生じ使
用不可能となる。Furthermore, since the airless spray gun injects high-pressure paint, the amount of spray is too large, causing problems such as dripping of the paint. In order to reduce the amount of paint dripping, an extremely small nozzle opening must be used, and even paint that has been thoroughly filtered will become clogged and unusable.
本発明は上記実情に鑑み、予め、圧縮空気と液体（塗料

能とした液体吹付方法およびその装置を提供することを
目的としたものである。In view of the above-mentioned circumstances, the present invention is designed to spray a mixture of compressed air and liquid (paint) into an atomized mixture from a nozzle through a transfer pipe, thereby making it possible to spray liquid into narrow grooves. The object of the present invention is to provide a spraying method and apparatus.

る。Means for Solving the Problems> The present invention provides a mixing chamber where an air passage and a liquid passage formed in a part of the spray gun body merge, and in which compressed air and liquid are fed through separate passages. The mixture is mixed and atomized, and while maintaining this state, it is sent to a transfer pipe and atomized from a closed nozzle provided at the tip of the transfer pipe.

The mixture is atomized and guided to an opening nozzle via a transfer pipe extending to the tip, and is injected to the outside from the opening nozzle. Therefore, the opening nozzle (injection nozzle) may have a minimum shape and can spray to small areas. Moreover, by bending this transfer pipe, it is possible to give a return component to the spray, making it possible to coat the inner surfaces of objects of various shapes. Of course, this opening nozzle can be arbitrarily selected from a plurality of nozzles having different jetting directions.

ことによって対応がはかれる。<Effects of the Invention> As described above, the liquid spraying method and device of the present invention have the following effects:
Compressed air and paint are made into a liquid mixture in advance in a mixing chamber inside the gun body, and this is led to the open nozzle at the tip through a transfer pipe connected to the gun body, so the open nozzle itself can be made smaller. Therefore, in combination with the preceding transfer pipe, the opening nozzle can be carried into a detailed area of the object to be coated. Further, in experiments conducted by one of the inventors, it has been found that even if this mixed gas/liquid is transferred for more than 70 degrees in a transfer pipe, no shortness of breath that would impede the coating is observed. Further, by adjusting and reducing the amount of paint sprayed, atomization becomes better, thereby making it possible to make the tip of the opening nozzle extremely small and to freely set the spray direction. In addition, if the elbow is placed in front of the opening nozzle, the injection direction can be set as the return direction, making it easier to paint the upper surface of the lip inside the C-shaped steel, the return part in the deep groove, the inner surface of the tank, etc. It can also be adjusted by hand using a vibrating rotating nozzle mechanism. In addition, a plurality of opening nozzles can be arranged radially to easily spray in different directions. Of course, this transfer pipe is made of a flexible material and can easily change direction by itself. This allows the spraying distance to be set at an appropriate distance of 2 to 3 cm, making it possible to create the best coating film. Moreover, since it is sprayed from the nozzle as a mixed air flow, the amount of air spray can be adjusted from a small amount to a large amount.
Patterns can be selected from flat to round by changing the nozzle. Therefore, it is possible to apply the nozzle provided at the tip depending on the spraying material and the object, and this can be done by providing various nozzles.
