関する。[Detailed description of the invention] (Field of industrial application) The present invention relates to a coating device that paints the top surfaces of automobiles transported along a transportation route, and in particular, the invention relates to a coating device that paints the top surfaces of automobiles transported along a transportation route. This invention relates to a film that can form a film with a uniform thickness distribution.
（従来の技術）
従来、この種の自動車の塗装装置として、例え

る。(Prior Art) Conventionally, as disclosed in Japanese Patent Publication No. 50-19577, a coating device for automobiles of this type has been equipped with one top spray gun ( The top spray gun (paint gun) is mounted downward, and the top spray gun (paint gun) is controlled so that it can move up and down and left and right so that it always maintains a fixed distance from the top of the car, and the paint film is uniformly applied to the top of the car. It is known that it is formed in this way.

昇降装置とに分類される。 Conventionally, a pair of rotary coating machines (hereinafter referred to as bells) corresponding to the above-mentioned top spray guns are attached to the horizontal support frame, and each bell is capable of reciprocating in a direction perpendicular to the conveying direction. There is also known a so-called two-bell reciprocating type, which can be raised and lowered and whose top surface is painted. This type of device can be roughly divided into a gate-shaped lifting device in which the above-mentioned horizontal support frame is attached to a pair of vertical support frames erected on both sides of the conveyance path so that it can be raised and lowered, and a vertical lift device installed on one side of the conveyance path. It is classified as a single-arm lifting device in which the horizontal support frame is attached to a support frame in a cantilevered manner so that it can be moved up and down.
（考案が解決しようとする問題点）
ところが、上記の従来のものでは次のような問

が自ずと制留約され作業効率上問題があつた。(Problems to be solved by the invention) However, the above conventional method had the following problems. That is, in the former case, since the top surface of the car is painted with one top spray gun, the stroke required for reciprocating the top spray gun is long;
Therefore, since it takes time to make one reciprocating movement, the conveyance speed is naturally limited in order to evenly paint the upper surface of a car, which poses a problem in terms of work efficiency.
一方、後者の２ベルレシプロタイプの塗装装置

当する。 On the other hand, in the latter 2-bell reciprocating type painting equipment, since the top surface of the car is painted with 2 bells, the stroke required for the reciprocating movement of each bell is shortened to almost half compared to the former, and the conveyance speed of the former is reduced by approximately half. Although this solves the problem of work efficiency due to constraints, the problem arises that the paint film becomes thinner in the center of the upper surface of the car. That is, as shown in Fig. 3, the spacing L between the bells b, b, which spray the paint a, is set to, for example, approximately 60 to 70 cm in consideration of coating efficiency, and Since the paints a and a are charged to, for example, about -90KV to increase the coating efficiency, the rotary sprayer is charged with electrical interference (electrostatic repulsion) between the paints a and a. As shown in the diagram, the top surface d of the car c
The sprayed paints a and a repel each other in the center of the vehicle (front bonnet, roof, trunk lid, etc.) and move away from each other, and the amount of paints a and a sprayed in the center is different from that of other parts. As a result, unevenness in the thickness of the coating film e occurs in the central portion (see FIG. 4a). In Figure 4,
f refers to a portion corresponding to the central portion of the upper surface d of the automobile c. Incidentally, FIG. 4b shows the electric field regions g, g of the charged paints a, a sprayed from the respective bells b, b. The gap between the electric field regions g and g corresponds to a portion f corresponding to the central portion of the upper surface d of the vehicle c.

Occur. It is also possible to lengthen the stroke of each bell b, b, but in this case, the paint a
The spray area is expanded outward to the side of the vehicle C, and as a result, an excess of paint a is sprayed onto the rain rail outer, etc., and this excess paint may cause the paint a to sag.

By appropriately setting the positional relationship between the two bells (rotating atomizing electrostatic painting guns) that paint the top surface of automobiles, it is possible to improve the efficiency of painting work while also improving the efficiency of both bells (rotating atomizing electrostatic painting guns). The purpose of the present invention is to avoid electrical interference of the paint that is rotary sprayed from the vehicle and to form a uniform thickness distribution of the paint film on the upper surface of the automobile.

Each painting gun 12, 12 supported by
The upper surface of the automobile M is painted by moving it independently up and down and left and right above the upper surface of the automobile M. At this time, since each of the painting guns 12, 12 is shifted in the front and back and left and right positions, the distance between them is wider by L 1 -L than in the conventional case where the painting guns b, b are arranged facing each other.

For example, two painting guns 12, 12 are provided on the crossbeam 5 so as to be able to move back and forth, for a total of four painting guns 12.
It is also possible to configure the upper surface of the automobile M to be painted. At this time, the above-mentioned painting guns 12, 12 provided on the crossbeam 5 need to be held at a predetermined interval to avoid electrical interference (electrostatic repulsion) of the rotary sprayed paint. .

うにしてもよい。 In addition, each of the painting guns 12, 12 is configured to be movable up and down relative to the crossbeam 5 using a fluid pressure cylinder, and when moving the painting from the front panel to the roof or from the roof to the trunk lid, the crossbeam 5 is moved up and down. It may also be possible to quickly prepare the coating position by a synergistic effect with the expansion and contraction operation of the fluid pressure cylinder.

の両立を図ることができる。(Effects of the Invention) As explained above, according to the automobile painting apparatus of the present invention, at least two painting guns are shifted from left to right and front to back, and each is independently moved up and down and left and right to transport the paint. Since the upper surface of the car on the road is painted, the distance between the two painting guns is wider than in the conventional system where each painting gun is arranged facing each other, so the paint that is sprayed rotatingly from both the painting guns is increased. Electrical interference (electrostatic repulsion) can be avoided, and the film thickness distribution of the paint film on the top surface of the car can be uniform by making the amount of coating on the central part of the car's top surface equal to that of other parts. Therefore, it is possible to achieve both improvement in painting work efficiency and uniformity of the thickness of the coating film.
