Description of the Related Art When painting a long member such as a door sash, it is necessary to perform painting while moving the painting gun along the longitudinal direction of the door sash, but the paint is sprayed in only one direction. Using a painting gun requires multiple reciprocations of the painting gun to coat the entire surface of the door sash. In such a case, for example, an annular coating gun provided with a plurality of nozzles radially arranged toward the center, which is described in Japanese Utility Model Publication No. 3-123555, is used, and the center of the annular coating gun is used. If you paint by moving the painting gun along the longitudinal direction of the door sash with the axis aligned with the longitudinal direction of the door sash, you can paint the entire surface of the door sash without reciprocating the painting gun. it can.

スキングしなければならないという不具合が生じる。In the above-mentioned conventional coating method, the paint sprayed from each nozzle adheres to the surface of the door sash located near the center of the coating gun, but all of the sprayed paint is the door sash. The paint that did not adhere to the surface of the door sash and that did not adhere to the surface of the door sash is scattered from the painting gun to the outside. At this time, if the paint spray direction from each nozzle is not tilted, the paint will be scattered over a wide area, and the paint will be spread even in the groove part of the door sash surface, so when using a so-called air atomization type nozzle. This scattering is particularly strong, and the scattered paint is applied to the door body and the like, which causes a problem that the door body and the like must be masked over a wide range.

を特徴とする。In order to achieve the above object, the present invention provides a door sash near the center of an annular coating gun provided with a plurality of nozzles arranged radially toward the center. In the method of painting the door sash by moving the painting gun along the longitudinal direction of the door sash,
Inclining the paint spraying direction of each nozzle to one side along the center axis of the coating gun so that the paint sprayed from each nozzle is scattered to one side along the center axis, and the center axis of the coating gun is doorsashed. Is inclined by a predetermined angle with respect to the longitudinal direction so that the mist-like paint sprayed from the nozzle does not reach the portion other than the door sash such as the door body.

On the other hand, the door body and the like are located on an extension of the door sash in the longitudinal direction. Therefore, if the central axis of the painting gun is tilted with respect to the longitudinal direction of the door sash, the paint scattered from the painting gun does not reach the door body or the like.

通路である。DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, reference numeral 1 is an annular coating gun, which is attached to the tip of an arm 3 of a coating robot (not shown). The coating gun 1 is configured such that a plurality of nozzle units 2 having nozzles 21 and a plurality of manifold blocks 31 are alternately connected on the same circumference, and the nozzle units 2 are radially arranged at equal intervals. There is. Each of the nozzles 21 is inclined to one side by a predetermined angle (for example, 30 degrees) with respect to the center direction of the coating gun 1, and the paints sprayed from the nozzles 21 collide with each other in the vicinity of the center and then are scattered toward one side. I decided to do it. The manifold block 3
1 is not attached at one place, and an opening 32 is provided, and the opening 3
The door sash S was allowed to enter and exit the painting gun 1 via the 2 button. In addition, the nozzle unit 2 sandwiching the opening 32
A cover plate 33 was attached to the end face of the nozzle unit 2 to close the various passages 22 to 25 of the nozzle unit 2. Each passage 22-25
Is the manifold block 3 between each nozzle unit.
1 and the passages provided in the arm 3. Each nozzle unit 2
Has a built-in air valve (not shown) that prevents the paint supplied through the passage 22 from reaching the nozzle 21, and when air pressure is supplied through the passage 23, the air valve opens. The paint is supplied to the nozzle 21 from the passage 22. The passage 24 is a supply passage of air for atomizing the paint sprayed from the nozzle 21, and the passage 25 is a passage for venting air when the air valve is operated.

And a door sash S connected on it,
The door sash S includes a front inclined portion Sa and a rear vertical portion S.
c and a horizontal portion Sb connecting the two. In addition, A is a straight line indicating the longitudinal direction of the inclined portion Sa,
B is a straight line showing the longitudinal direction of the horizontal portion Sb, C is a straight line showing the longitudinal direction of the vertical portion Sc, and L is the central axis of the coating gun 1. First, the inclined portion Sa is put into the coating gun 1 through the opening 32 of the coating gun 1, and the coating gun 1 is moved upward from the lower end side of the inclined portion Sa to coat the inclined portion Sa. At this time, the coating gun 1 is moved along A, but its posture is tilted so that an angle of θa is formed between L and A. By the way, the direction of tilting the L is not particularly limited, but the tilting direction is determined so that the coating mist scattered along the L does not reach the door body Dd or the vehicle body (not shown).

Do. When the horizontal portion Sb is coated, the paint that scatters even if L is matched with Sb is the door body D.
It is not necessary to incline L with respect to Sb as long as it does not affect d or the like. Then, when the painting of the horizontal portion Sb is completed, the painting gun 1 is once detached from the door sash S, and the vertical portion Sc
The vertical portion Sc is put in the coating gun 1 by moving it to the lower end side, and the coating gun 1 is moved upward along C as it is to coat the vertical portion Sc. Also, when coating the vertical portion Sc, L is inclined by θc with respect to Sc so that the scattered paint mist does not reach the door body Dd.
