(see Fig. 7), the coating film became non-uniform, and this was a major problem in terms of coating quality.

That is, in FIG. 7, an appropriate coating film is formed on 8 parts of the object 6 to be coated, but the coating film is thin on the A part, and on the other hand,
At 0 parts, the coating film becomes thick.

Therefore, an object of the present invention is to make the relative movement locus of the painting gun with respect to the object to be painted, which is transported by the conhair, in a direction perpendicular to the direction of conveyance of the object to be painted, so that It is an object of the present invention to provide a coating device capable of forming a uniform coating film and improving the quality of coating.

[Means to solve the problem]

In order to achieve the above object, the main means adopted by the present invention is that the main means is a coating device that is equipped with a coating gun movable in the longitudinal direction for spraying paint onto the object being conveyed by a conveyor. This is a coating device in which the device main body is supported so as to be able to move 18 times in the conveying direction of the object to be coated.

[Effect]

By moving the coating gun on the main body of the coating apparatus which is tilted by being moved 1z in the conveyance direction of the object to be coated, the locus of movement of the painting gun relative to the object to be coated which is being conveyed by the conveyor can be determined by can be perpendicular to the conveying direction.

As a result, a uniform coating film can be continuously formed on the object to be coated.

In this case, by appropriately controlling the swing angle of the coating device body and the moving speed of the coating gun on the coating device body, it is possible to follow changes in the moving speed of the object to be coated and always maintain a uniform coating film. can be formed.

(Examples) Examples embodying the present invention will be described below with reference to the accompanying drawings to provide an understanding of the present invention.The following embodiments are examples embodying the present invention, and include: It is not intended to limit the technical scope of the present invention.

FIG. 4 is a schematic diagram of a coating apparatus according to another embodiment of the present invention.

In the coating device 7 according to this embodiment, as shown in FIG. 1, for example, in the vertical direction (longitudinal direction) of the coating device main body 8,
- a set of painting guns 9.9 is movably arranged;

The coating device main body 8 is mounted on a base so that it can swing within an angle range of α about a lower fulcrum E in the conveyance direction (arrow 5 direction) of the object to be coated 6 (see FIG. 6). It is arranged on a stand 10. In this case, the value of the swing angle α of the coating device main body 8 is appropriately set based on the moving speed of the coating gun 9 on the coating device main body 8 and the moving speed of the conveyor 4 that conveys the object to be coated 6. be done.

The coating device main body 8 has a t provided inside the base 10.
! It is oscillated by the 1fjJJ machine side (not shown) and can be manually adjusted as appropriate by a manual setting mechanism built into the lateral movement mechanism.

The coating device 17 according to this embodiment is configured as described above.

Continuing on, the procedure for painting the object to be painted 6 conveyed by the conveyor 4 using the painting device 7 will be explained.
This will be explained based on FIGS. 1, 2, 3, and 6.

First, the coating apparatus main body 8 is swing-driven to the position shown by the solid line in FIG. 1 with respect to the object 6 to be coated that is conveyed by the conveyor 4 in the direction of the arrow 5.

When the object 6 to be painted reaches a position corresponding to the coating gun 9, the object 6 moves in the direction of the arrow 5, and the gun 9 moves from the upper limit position (L) to the vicinity of the fulcrum E. It is driven to move at a predetermined speed while ejecting paint toward the lower limit position. When the coating gun 9 reaches the lower limit position, the coating gun 9 is temporarily stopped, and the coating apparatus main body 8 is moved to the position indicated by the two-dot diagonal line in FIG. direction) by an angle α.

Thereafter, the coating gun 9 is driven to move from the lower limit position toward the upper limit position (R) while ejecting paint.
