2. Description of the Related Art Conventionally, spray coating is performed by spraying a spray gun so as to have a constant film thickness while applying a spray pattern in a circular (round) or elliptical (flat) spray pattern. Drive. In order to paint a wide area efficiently with one spray gun, it is necessary to increase the spray pattern width as much as possible and apply the paint with a small number of coatings.

[0003] In general, the spraying efficiency of spray coating is very low as compared with brush or roller coating, and is usually about 50 to 60%. In the case of spray coating such as air spray or airless spray, compared to the center of the spray pattern,
The coating efficiency tends to decrease as it approaches the end of the pattern. This is because the atomized air flow and the accompanying air flow act as a carrier air flow that collides with the object and carries away the atomized particles, so that the atomized particles at the end of the pattern are closer to the object. Since the inertia force is low, it is easily affected by the carrier air flow. For this reason, increasing the pattern width has been a factor that causes a decrease in coating efficiency.

[0004] In order to improve the coating efficiency, a spray is used.
It is necessary to reduce the pattern as much as possible to increase the inertial force of the atomized paint particles in the direction of the object to be coated, and it is effective to spray the paint particles at a short distance as one means. That is, spray
By spraying while moving the gun at a coating distance of several centimeters, it is possible to cause the atomized paint particles to collide with the object to be coated at a high coating speed. As a result, the coating efficiency becomes 90%. % Or more can be secured. However, in this case, the spray pattern opening angle must be at most about 30 degrees.

However, when the spray distance is reduced as described above, the spray pattern width becomes extremely small, and as a result, the wet coating film sprayed by one spray gun moving operation becomes too thick. This causes paint film defects such as sagging and Nagare.

In a normal spray gun, the outer diameter of the body is several times as large as the outer diameter of the nozzle portion for atomization. The maximum pitch is about 2 cm. In general, it is known that in order to obtain a uniform film thickness distribution, the coating pitch of the spray pattern is set to 1/2 or less of the effective spray pattern width. Therefore, the pitch between nozzles is 2c
m indicates that if the effective spray pattern width is 4 cm or less, the film thickness distribution may be non-uniform.

[0008] The coating distance of close-range coating in which a coating efficiency of 90% or more can be expected is within about 5 cm. If an effective spray pattern width of 4 cm or more is to be secured at this distance,
The spray pattern opening angle must be about 90 degrees or more, which is difficult to achieve with a conventional spray gun or spray nozzle. Even if the pattern is forcibly expanded, it is difficult to secure a coating efficiency of 90% due to the influence of the flow of the conveying air.
