閉しる。25 is a paint storage tank, and 26 is a filter. In addition, M is a motor, 27 is an operation panel equipped with a known automatic control circuit (not shown), 28 is a three-way valve, and 2 and 9 are air curtain operation valves, and the three-way valve 28 operates the operation and stop of the spray gun 3. However, if the air curtain is not required, the operating valve 29 is closed.
上記構成において、操作盤２７の図示しない電源を入れ
、真空ブロワＢ及びコンプレッサーＣを作動させ、塗装
ガンＡを使用する。In the above configuration, the power (not shown) of the operation panel 27 is turned on, the vacuum blower B and the compressor C are operated, and the coating gun A is used.

散が確実に防止される。That is, the paint is sprayed from the nozzle 3a of the spray gun 3 toward the object to be painted, such as the wall P, but the paint mist floating between the booth hood l and the wall P is sucked by the vacuum blower B and adheres to the filter hood. Therefore, scattering of the booth hood 1 to the outside is reliably prevented.

ことができる。At this time, in the space between the booth hood 1 and the wall P, turbulence occurs in the flow of the atomized paint sprayed from the spray gun 3 (mainly vortices at the time of spraying from the nozzle 3a), resulting in poor finish of the paint film. However, in such a case, by introducing air from outside the booth hood 1 through the ventilation path 11, a natural flow is created in the atomized paint, which is different from the case without a booth hood. A similar uniform coating film can be formed. The amount of ventilation from the ventilation passage 11 can be adjusted depending on the type of paint, etc. by changing the opening degree of the shutter 12.

応して最適条件を選択できるようにしである。On the other hand, if the distance between the booth hood 1 and the wall P is large due to scaffolding or the like, or if the worker is exposed to crosswinds during outdoor work, the scattering prevention hood 4 alone cannot completely prevent mist from scattering. In this case, compressed air is supplied to the annular pipe 9 by the operation valve 29, and the air is blown toward the wall surface P from the air outlet 9a to form an annular air curtain Q and blow the inside of the booth hood 1. Separate from outside air. This makes it possible to prevent mist from scattering from the booth hood 1 and adverse effects on the paint film due to crosswinds. The air volume and pressure of the air curtain Q, the suction air volume by the vacuum blower B, etc. are so set that the optimum conditions can be selected according to the type of paint, coating conditions, etc., using the pressure regulating valve v2 and the like.

もよい。Although the above example has been described in which the booth hood 1 surrounding the spray gun 1 is provided separately from the mist suction hood 14, it is also possible to integrate the two, or the booth hood 1 may be provided with a handle 21 to make it portable. Alternatively, a mounting bracket or the like for mounting on a traveling robot (not shown) may be provided.

となる。As described above, in the present invention, a mist scattering prevention hood is provided in front of the nozzle of the spray gun, a booth hood is provided on the outer periphery of the hood, a mist suction path is formed between both hoods, and the mist is sucked through the filter in front of the prevention hood. Since the mist is sucked, it is possible to prevent the mist from scattering and improve the working environment. In addition, a ventilation path is provided between the mist 1F & scatter prevention hood and the booth hood to prevent swirling currents in the hood and form a uniform coating film, so operators do not need any special skill. , can be easily spray painted. Furthermore, an annular pipe for supplying compressed air is installed in the front of the booth hood to form an air curtain between the booth hood and the surfaces to be coated, so it is not affected by crosswinds, etc.
Uniform coating and prevention of mist scattering are achieved, and therefore, unmanned painting is possible by attaching this to a traveling robot or the like.
