ようになっている。Further, the automobile body W is intermittently transported by a floor conveyor 1 that operates for one minute and stops for three minutes, for example.
しかして、前段の自動塗装ゾーン９で自動車ボディＷの
塗装が終了すると、フロアコンベア１を１分間作動させ
て当該自動車ボディＷを次段の手吹塗装ゾーン１１に移
送する。When the painting of the car body W is completed in the automatic painting zone 9 at the previous stage, the floor conveyor 1 is operated for one minute to transfer the car body W to the hand-blown painting zone 11 at the next stage.
この１分間は自動塗装ゾーン９と手吹塗装ゾーン１１の
何れにおいても塗装が行他れないから、塗装ブース２内

きによる補正塗装を行う。When the car body W arrives at the hand-blown painting zone 11, the floor conveyor 1 is stopped for 3 minutes, and when there is 1 minute left in the stop time, the wind speed of the clean air flowing into the painting booth 2 is adjusted to the normal speed. At the same time, hand-blown correction painting is performed on the automobile body W that has been completely flushed with the solvent.

に低減されることとなる。In this way, not only the length of each zone is shortened (but also a setting zone is not required between painting zones 9 and 11, the total length of the painting booth 2 is shorter than that shown in Fig. 1). Furthermore, it becomes shorter, the installation space is significantly reduced, and the equipment cost and running cost of the entire painting booth 2 are significantly reduced.
以上述べたように、本発明方法によれば、塗装ブースの

れた効果がある。As described above, according to the method of the present invention, it is possible to shorten the length of the coating booth and significantly reduce the installation space, and at the same time, the coating surface of the coating film is good, and automatic coating using a manipulator is possible. This has the great effect of making it extremely easy.
また、塗装ブースが小型化されると共に、当該塗装ブー
ス内に清浄空気を流通させる空調装置や給排気ファンの
容量も小さ（て済むから、塗装ブース全体の設備費を大
幅に低減することができるという効果がある。In addition, as the paint booth becomes smaller, the capacity of the air conditioner and air supply/exhaust fan that circulate clean air within the paint booth is also small, which significantly reduces the equipment cost of the entire paint booth. There is an effect.
更に、コンベアが作動して被塗装物が移送されている間

動力費を節減してランニングコストを大幅に低減できる
という優れた効果もある。Furthermore, while the conveyor is operating and the object to be coated is being transferred, the flow velocity of clean air supplied into the coating booth is reduced, reducing power costs for air conditioners and air supply/exhaust fans. It also has the excellent effect of significantly reducing running costs.
