Abstract

PURPOSE:To contrive to form an uniform finish coating surface with efficiency, by spraying coating material to the surfaces of a long-size work part being conveyed by a conveying means and forming a uniform finish coating on the sprayed surfaces by a leveling means, while simultaneously coating the other surfaces by a coating means. CONSTITUTION:A spray means 9 sprays coating material to a plurality of surfaces of a long-size work part 5 being conveyed by a conveying means 7. A leveling means consisting of brushes 11 forms a uniform finish coating on the surface sprayed by the spray means 9, while a coating means consisting of a roller 15 applies the coating to the other surfaces in parallel with the leveling operation by the leveling means 11, whereby an uniform finish coating can be attained with efficiency.

Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention (Industrial Field of Application) This invention relates to a long object coating device that can simultaneously coat each surface of a continuous long object.

(Prior art) Generally, in long workpieces such as elevator rails,
Coating each surface of the workpiece can be done by brushing or by spraying, and with either method, the coating is applied from one direction, and when the coating on the - side is completed and the painted surface is dry, it is reversed and the next side is applied. Painting is carried out by repeating the process of moving on to the painted surface.

(Problems to be Solved by the Invention) As mentioned above, in the conventional method of painting, the work is time-consuming and work efficiency is low because the painting is done on one side and then on the other side. Because of this, there were problems such as difficulty in obtaining a uniform finished surface.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an apparatus for coating long objects that has good working efficiency and can provide a uniformly finished surface.

[Configuration of the Invention (Means for Solving the Problems) In order to achieve the above object, the present invention includes applying paint to the painted surface of a workpiece having a plurality of painted surfaces transported by a transporting means. A spraying means for spraying, a leveling means for uniformly leveling the paint sprayed by the spraying means, and an application means for applying the paint to another painted surface in parallel with the work by the leveling means. We are prepared.

(Function) According to such a long object coating apparatus, paint is sprayed by the spraying means onto the painted surface of the long object sent by the conveyance means. The sprayed paint is leveled into a uniform finished surface by a leveling means. At the same time, other painted surfaces are applied by the application means, and multiple painted surfaces are simultaneously applied, and
The paint will be applied evenly.

(Embodiment) Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings of FIGS. 1 and 2.

In the figure, numeral 1 indicates a paint recovery tank of the coating device 3, which has a long shape from front to back.

In front of the paint recovery tank 1, there is provided a conveyance roller 7 for conveying a long workpiece 5 in the direction of the arrow X, and in tandem with the paint recovery tank 1, there is a conveyance roller 7 for conveying the workpiece 5 after painting is completed while holding it there. A device (not shown) is provided.

Above the paint recovery tank 1, a pair of left and right injection nozzles 9.9, a pair of left and right first brushes 11.11, and a pair of left and right second brushes 13.13 are arranged from the front end side. 1. An applicator roller 1 is located between the second brushes 11 and 13.
5 is placed.

The injection nozzle 9.9 and the first brush 11.11 are mounted on the mounting shaft 1
They are fixedly supported by a support frame 19 that can move up and down using 7 as a fulcrum, and are positioned at approximately the same height.

The support frame 19 rises by a predetermined distance J when the roller 21 provided at the tip rides on the workpiece 5, and the support frame body 19 rises by a predetermined distance j, and the first.
The injection nozzle 9 and the first
The brush 11 has a gauge function that allows the brush 11 to be correctly positioned.

The injection nozzle 9 is connected and communicated with the pump device 23 so that the paint in the paint tank 25 is sprayed when the pump device 23 is operated.

The application roller 15 is rotatably supported at both ends by an arm 27 that is rotatable about an arm shaft 27a as a fulcrum.
The lower surface is located below the paint liquid level in the paint recovery tank 1. Furthermore, the application roller 15 is always urged upward by a biasing spring 29 provided on the arm 27, so that contact pressure is ensured to ensure that the application roller 15 comes into contact with the third painted surface 5b of the workpiece 5. .

On the other hand, the second brush 13.13 is fixedly supported by the fixed frame 31 and is set at almost the same height as the first brushes ii and 1i in front, and is leveled with the first brush 11. It is used for finishing applications that cannot be completely finished.

The paint 1 ft 25 and the paint recovery tank 1 are connected by a communication path 33, and the excess paint sprayed from the injection nozzle 9.9 is transferred from the paint recovery tank 1 to the paint tank 25 via the communication path 33.
The circulation is repeated in which the liquid is returned to , is sent out again by the pump device 23, and is injected from the injection nozzle 9.9.

In the coating apparatus configured in this way, the conveyance roller 7
The long workpiece 5 transported by the coating device 3
In the first step of the process, the first and second painted surfaces 5a of the workpiece 5 are
, 5a from the spray nozzle 9.9, the first brush 11.11 acts to uniformly level the paint. Subsequently, the coating roller 15 comes into contact with the third coating surface 5b of the workpiece 5 to apply the paint. Then, in the final process, the first
．． The second brush 13.13 acts on the second painted surfaces 5a, 5a, and the surface is leveled to a uniform finish. Second. The third painted surfaces 5a, 5a, 5b can now be obtained at the same time.

In this embodiment, the spray nozzle 9, brush 11, and roller 15 are arranged optimally for the elevator rail, but by changing these layouts, it can be used for workpieces with other angles, channel shapes, etc. Become adaptable.

[Effects of the Invention] As explained above, according to the coating apparatus of the present invention, it is possible to simultaneously coat each coating surface of a long workpiece having a plurality of coating surfaces, thereby greatly improving work efficiency. can be achieved. Moreover, a uniform finished surface can be obtained and the quality is also stable. Furthermore, the working environment for the painting process is also very favorable.
