る。[Detailed description of the invention] (Field of industrial application) The present invention relates to a device for applying electrostatic coating to the sides of workpieces that are continuously moving along a conveyance path, and is particularly applicable to painting the sides of automobile bodies. It is something that is used.

95252, 61-143669, etc. are known, and in these, for example, as shown in FIG. H, M, and L are spaced apart by a pitch P in the moving direction of the vehicle body W, and the heights are set as L, M, and L.
It is arranged so that it becomes higher in the order of H or lower in the reverse order, and by arranging it in this way,
The distance between each gun is large enough to prevent paint particles emitted from each gun from interfering with each other.

させていることに起因する。(Problem to be solved by the invention) If painting work is continued with each gun arranged in this way, paint particles emitted from the other guns M and H, especially M, will appear on the lowest gun L and the outer surface of the stand. There is a tendency for a part of to be drawn in the direction of arrow A,
A phenomenon occurs in which paint adheres to the outer surface and becomes dirty, and the paint is wasted. This is due to the fact that a downward airflow is generated in the painting room to collect floating paint.

したことを特徴とする。(Means for solving the problem) The present invention solves the above problem by changing the arrangement of each gun from the conventional one. In a coating equipment in which three electrostatic coating guns of different heights, top, middle, and bottom, are installed on the side surface, and these guns paint the side surface of the workpiece, the three guns The painting gun is characterized in that the middle painting gun is installed farthest from the lower painting gun in the direction of the conveyance path, and the upper painting gun is installed in the middle thereof.

The actual distance from the lower gun to the middle gun and upper gun can be secured sufficiently without increasing the total length of the arrangement range of each upper, middle, and lower gun, and paint particles are prevented from adhering to the lower gun. Ru.

In FIGS. 1a, b, and c, reference numeral 1 denotes a conveyance path for a workpiece W, and 2 denotes a group of guns for painting the side surface of the workpiece, which are fixed on the side surface of the conveyance path 1 and consist of a lower gun 2L, a middle gun 2M, and an upper gun 2H. In addition, 3 is the front and back surfaces of the workpiece W,
The gun group that paints the top surface changes the discharge direction while moving along the path 3a.

く、したがつて、下部ガン２Ｌの汚れが少ない。 The upper, middle, and lower painting guns are lower, upper, and middle, that is, 2L, 2H, and 2M when viewed from the traveling direction of the workpiece W.
They are arranged at a constant pitch P in _the order of
The distance l ₂ between and gun 2H is slightly smaller than 2P. Since these distances l ₁ and l ₂ are considerably longer than the distance between the guns L and M in FIG. 3, paint particles emitted from the upper gun 2H and middle gun 2M have difficulty reaching the lower gun 2L. The rate of adhesion to the gun 2L is low, and therefore the lower gun 2L is less contaminated.

前記実施例は、ワークＷの進行方向上流側から
２Ｌ，２Ｈ，２Ｍの順に並べてあるが、これとは
逆に第２図に示すガン群４のように下流側から４
Ｌ，４Ｈ，４Ｍの順に並べてもよく、同様の効果
が得られる。 In the above embodiment, guns 2L, 2H, and 2M are arranged in the order from the upstream side in the traveling direction of the workpiece W, but conversely, guns 4 are arranged from the downstream side as in the gun group 4 shown in FIG.
The same effect can be obtained by arranging them in the order of L, 4H, and 4M.

また、各ガンの吐出量を、下部ガンを最大とし

ガンへの付着量を更に減少させることができる。
この場合に中部ガン、下部ガンを少しずつ上方へ
ずらせて散布量の均一化を図る必要がある。 Moreover, if the discharge amount of each gun is set to the maximum at the lower gun and decreased in the order of the middle gun and the upper gun, the amount of adhesion to the lower gun can be further reduced.
In this case, it is necessary to shift the middle and lower guns upward little by little to equalize the amount of spray.

止することができる。(Effect of the invention) As described above, the middle and upper painting guns can be installed at the required distance without changing the maximum horizontal distance from the lower painting gun, so the lower painting gun can be installed at the required distance without increasing the overall length of the painting equipment. It can prevent stains.
