As shown in (1), it is taken into the booth defined by the above three shells. Inside this booth, paint spray nozzles 5, 6 and 7 are provided facing the surface of the frame structure to be painted. The paint spray nozzles 5, 6 and 7 are attached to holders 8, 9 and 10 inserted through insertion holes or slits provided in corresponding shells, and horizontally moved, lifted and rotated by a device (not shown). And the spray of paint is controlled.

The insertion holes, slits, etc. of the paint spray nozzle holders 8, 9 and 10 can also be provided on the side wall or ceiling of the shell. The holder does not have to be a single rod-shaped body inserted from the outside of the booth, but can be, for example, an articulated arm attached inside the booth. Also, when using such an articulated arm, it is recommended to provide not only a paint spray nozzle but also an infrared video camera or other sensor. In addition, it goes without saying that the number and orientation of the paint spray nozzles and the method of moving the paint spray nozzles are appropriately changed according to the shape and arrangement of the surface to be painted, the purpose of painting and the ability of the holder. Exhaust pipe 2e, 3
e and 4e are connected to a suction port of an exhaust blower (not shown) via a header (not shown). By operating the exhaust blower before the start of coating, an air flow passing through the filters 11, 12 and 13 is generated to exhaust the inside of the booth.

When the painting work is started, the paint mist scattered inside the booth is sucked by the air flow passing through the filters 11, 12 and 13, and is collected by the filter to remove the paint mist. Exhaust pipe is exhaust pipe 2e, 3e
And 4e, and is discharged from the exhaust blower discharge port. The position of the exhaust pipe connection port is not limited to the top of the booth shown in the figure,
It can be side or bottom. When a large amount of exhaust gas is emitted and odor is generated and there is a risk of environmental pollution, it can be released into the atmosphere after being burnt. The filters 11, 12 and 13 for collecting paint mist that scatters during paint work
It is recommended to have a replaceable structure, for example, to provide each shell with an insertion hole for taking out and replacing. And such an insertion hole is provided on the top, side or bottom of each shell.

Therefore, it is desirable that the filter medium has a structure such that clogging due to the paint mist does not easily occur as shown in FIG. In FIG. 3, 131 and 132 are baffle plates having a large number of holes, 133 is a distance piece, 134 is a filter medium made of sponge or non-woven fabric, and 135.
Is a metal fitting for holding the filter medium. When exhaust gas containing paint mist passes between baffle plates, the direction of the flow is suddenly changed, so the mist in the exhaust gas collides with the baffle plate due to inertia and most of it is collected. The filter material is less likely to be clogged. When replacing the filter material, change the pressure loss of the filter as a guide.
The filter material removed from the booth is washed repeatedly with a solvent such as lacquer or thinner, or with water, and then used repeatedly.
