複数の色を取り替えながら塗装を行うことのできる回転
霧化静電塗装機が使用されており、このような回転霧化
静電塗装機では色替毎に染料供給経路を洗浄することが
できるようになっている。Rotary atomizing electrostatic atomizers that can paint while changing multiple colors are used, and with such rotary atomizing electrostatic atomizers, the dye supply path can be cleaned after each color change. It has become.
噴霧頭は運転後に塗装機から取り外されてその表面に付
着した汚染物を洗浄するようになっている。The spray head is removed from the sprayer after operation and its surface is cleaned of contaminants.
しかしながら、噴霧頭は多数の小さな噴出穴を有し、こ
の噴出穴も色替毎の洗浄によって洗浄されるが、運転後
には幾つかの穴が詰まっていることがあり、この噴出穴
の詰まりを除去するのは面倒な作業であった。However, the spray head has many small nozzle holes, and although these nozzles are also cleaned by cleaning every color change, some of the holes may be clogged after operation. Removal was a tedious task.
この噴出穴の洗浄作業は従来ブラシや針金を使用して行
っていたが、ブラシでは穴の内部を十分に洗浄すること
ができず、そして毛の固いブラシで磨くと表面に細かな
傷がつき、この傷がさらに汚れを促進させるという間ガ
があった。従って、針金を用いて人手によって一つずつ
穴を清掃することが必要であったが、この場合にも同様
に傷がつき、汚れもなかなか除去出来ない。さらに、穴
の洗浄のために超音波洗浄を用いることも考えられるが
、超音波洗浄を用いると温度が上がるので噴霧頭に歪み
が発生するという問題があった。Traditionally, cleaning of this spout hole has been done using a brush or wire, but the brush cannot sufficiently clean the inside of the hole, and cleaning with a hard-bristled brush leaves small scratches on the surface. However, there was a problem that this scratch caused further staining. Therefore, it has been necessary to manually clean the holes one by one using a wire, but this also causes scratches and makes it difficult to remove dirt. Furthermore, although it is possible to use ultrasonic cleaning to clean the holes, there is a problem in that the temperature rises when ultrasonic cleaning is used, causing distortion in the spray head.
上記問題点を解決するために、本発明による塗装機の噴
霧頭の洗浄方法は塗装機の噴霧頭を取り外し、この噴霧

ップ44によって閉じられる。The cleaning device includes a container 30 containing a cleaning solution, inside the container 330 a mounting post 32 is fixed vertically to the bottom of the container 30. A mounting plate 34 is horizontally attached to the intermediate portion of the mounting support 32. A six 34a is provided in the center of the mounting plate 34, and the cleaning liquid can move up and down through the six 34a. The mounting support 32 is stepped in the middle, and the thin part at the top is the spray head 10.
It can be inserted into the hole 10d in the axial direction, and a screw 36 is screwed into the upper end of the hole 10d. Therefore, the spray head 10 is supported by the mounting plate 34 and fixed by the screws 36. Top lid 3 of container 30
8 can be opened and closed for insertion of a spray head 10. Further, a cleaning liquid inlet 40 is provided near the upper end of the container 30, and a cleaning liquid outlet 4o is provided near the upper end of the container 30. These inlets 40 and outlets 42 are each closed by caps 44.

とが分かった。Advantageously, surfactants such as oleic acid esters, stearic acid esters, lauric acid esters are mixed in the cleaning liquid. In the example, a cleaning solution containing 5% by weight of sodium laurate to butyl acetate was used, and the spray head 10 removed from the paint sprayer was placed in the container 30.
The container 30 was vibrated in the direction of arrow A at a frequency of 20 [1z and an amplitude of 10 cm. As a result, in the spray head 10 in which 12 of the 90 ejection holes 10c were clogged, the clogs could be removed by cleaning for 6 hours. In addition, the overall appearance of the material, which had been contaminated with a white color, was restored to its original luster. In addition, the frequency of vibration is 10 to 50Hz
, an amplitude in the range of 5 to 20 cm has been found to be suitable.
