BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coating gun applicator which is attached to a coating gun for coating a coating material such as a building structure, and in particular, atomizes the coating material from a nozzle by a trigger operation. The present invention relates to a coating gun applicator that is attached to a spraying coating gun.

[0002]

2. Description of the Related Art Generally, as a coating gun, for example, a gun main body provided with a paint supply passage, a grip portion connected to the gun main body and capable of being held by one hand, and a detachable mounting portion at the tip of the gun main body are provided. Some include a nozzle that sprays paint from the supply passage in a mist state, and a trigger that opens and closes the paint supply passage of the gun body. And using this painting gun, for example,
When painting a painted object such as a steel frame member of a building structure, connect the painting gun to a pump that pumps the paint to the paint supply path of the gun body, point the nozzle at the painted object, and pull the trigger. As a result, the pressure-fed paint is sprayed from the nozzle in the form of mist, diffuses, adheres to the steel frame member, and is applied.

[0003]

By the way, in the above-mentioned coating gun, since the paint diffuses from the nozzle in the form of mist, not all of the sprayed paint adheres to the coated object, but a few percent of it. Is scattered around the paint. Since the scattered paint is in the form of a mist, it has a problem that it is easily sucked by the human body, causing a health problem, and that it adheres to something other than the painted object. In particular, some slow-drying paints are difficult to remove when they adhere, and if they are likely to adhere to anything other than painted objects, the surrounding area must be covered with a sheet, etc.
The work becomes complicated. Further, since the paint scatters, the coating gun has to be repeatedly reciprocated (for example, 4 reciprocations) with respect to the coated object in order to obtain a constant coating film, which makes the work extremely complicated. was there. Furthermore, there is a problem in that the paint is wasted due to the scattering. For example, the amount of paint used is increased by about 40% as compared with the case of hand painting using a brush or roller.

The present invention has been made in view of the above problems, and it is possible to prevent the paint from scattering and allow most of the sprayed paint to adhere to the object to be coated so that the paint can be effectively used and the human body and the paint can be coated. An object of the present invention is to provide an applicator for a painting gun that suppresses the influence on objects other than objects.

[0005]

In order to achieve such an object, the coating gun applicator of the present invention is a coating gun applicator attached to a coating gun for spraying paint from a nozzle in a mist state by a trigger operation. In the above, a cylindrical guide tube is detachably attached to the tip of the coating gun and regulates the spread range of the paint sprayed from the nozzle, and bristles are planted along the opening edge of the tip of the guide tube. And a brush portion to be formed.

[0006]

According to the coating gun applicator having the above structure,
Used by being attached to the tip of the painting gun. And
When painting a coated object using this coating gun, the brush portion of the applicator is applied to the coated object, the trigger of the coating gun is pulled, and the brush portion is brought into sliding contact with the coated object. As a result, the paint is sprayed in a mist form from the nozzle and adheres to the portion surrounded by the brush portion. In this case, the paint sprayed in the form of mist diffuses outward from the nozzle, but since this paint collides with the wall of the guide tube, its spreading range is restricted and surrounded by the brush part. In addition to being converged on the portion, the brush portion comes into contact with the object to be coated, so that the mist-like paint hits the brush portion and is absorbed in the brush portion, thus preventing the paint from scattering. Further, the paint that hits the wall portion of the guide tube flows and is absorbed into the brush portion. Then, when the brush portion is brought into sliding contact with the coating material, the coating material absorbed in the brush portion is applied to the coating material, and the coating material directly attached by the spray from the nozzle is smoothed in order.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A coating gun applicator according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 4, the coating gun applicator T according to the embodiment is detachably attached to the coating gun G. As the coating gun G, for example, as shown in FIGS. 1 and 2, a gun body 1 provided with a paint supply path (not shown), and a grip portion 2 connected to the gun body 1 and capable of being gripped with one hand. And a nozzle 3 detachably provided on the tip 1a of the gun body 1 for spraying the paint from the supply path in a mist state, and a trigger 4 for opening and closing the paint supply path of the gun body 1. The grip 2 communicates with the supply path of the gun body 1 and the tank 5
A connection portion 7 is provided which is connected to a pump 6 for pumping the paint inside.

A coating gun applicator T according to an embodiment is shown in FIG.
As shown in FIG. 3, a guide tube 10 detachably attached to the tip portion 1a of the coating gun G and a brush portion 20 formed at the tip portion of the guide tube 10 are provided.

The guide tube 10 has a substantially trapezoidal outer shape, and is formed in an elongated elliptical cross section so that the spread range of the paint sprayed from the nozzle 3 can be regulated.
It is formed in a tubular shape that gradually expands from the base end portion 11 to the tip end portion 12. The base end portion 11 is provided with a fitting 13 that is attached to the tip end portion 1a of the coating gun G.
The fitting 13 includes a connecting member 15 that encloses the nozzle 3 and has a male screw portion 14 formed on the outer periphery thereof, a male screw portion 8 formed on the tip 1a of the coating gun G, and a male screw portion of the connecting member 15. It is composed of a connecting pipe 16 which is screwed to 14 and connects both.

The brush portion 20 is formed by implanting bristles along the entire peripheral edge of the tip end opening of the guide tube 10. The bristles of the brush portion 20 are arranged to have the same length, and
The front end 21 of the is located substantially on the same plane and can come into contact with the coated object 22.

Therefore, when the applicator T according to this embodiment is attached to the coating gun G, the base end 11 of the guide tube 10 is attached.
Is attached to the tip portion 1a of the coating gun G via the mounting bracket 13. In this case, the connecting pipe 16 of the fitting 13 is attached to the tip portion 1a of the coating gun G and the male screw portion 8 of the connecting member 15,
It only needs to be screwed into 14, so it can be easily installed.

When the coating gun 22 is coated with a coating material 22 such as a steel member of a building structure, a pump is applied to the connecting portion 7 of the grip portion 2 of the coating gun G as shown in FIG. 6 is connected so that the paint in the tank 5 can be pumped by this pump 6. Then, as shown in FIG.
Apply the brush portion 20 of the applicator T to the coating object 22, and apply the coating gun G.
The trigger 4 is pulled to bring the brush portion 20 into sliding contact with the coating material 22. As a result, the paint supply path of the gun body 1 is opened, and the pressure-fed paint is sprayed in a mist form from the nozzle 3 and adheres to the portion surrounded by the brush portion 20.

In this case, the paint sprayed in the form of mist diffuses outward from the nozzle 3, but this paint is guided by the guide tube 1.
Since it collides with the wall portion of No. 0, the expansion range thereof is regulated and converged to the portion surrounded by the brush portion 20. Further, since the brush portion 20 is in contact with the coating material 22, the mist-like paint hits the brush portion 20 and is absorbed in the brush portion 20. In addition, the paint that hits the wall portion of the guide tube 10 flows over the wall portion, reaches the brush portion 20, and is absorbed into the brush portion 20.

Since the brush portion 20 is brought into sliding contact with the coating material 22, the coating material absorbed in the brush portion 20 is applied to the coating material 22 and the coating material directly deposited by the spray from the nozzle 3 is removed. They are leveled in order.

Therefore, the guide tube 10 and the brush portion 20
The paint does not scatter to the outside, and adheres to the portion of the coated object 22 surrounded by the brush portion 20. As a result, since the paint does not scatter, it is suppressed that the paint is sucked into the human body, and the situation that the paint adheres to an object other than the painted object 22 is also suppressed. Further, since there is no scattering, it is not necessary to cover the periphery with a sheet or the like, and the workability is improved accordingly. Furthermore, since the paint that is not scattered and is absorbed in the brush portion 20 is applied to the coated object 22, it is easy to obtain a desired coating film. You don't have to reciprocate the gun G many times.
A round trip is sufficient, and the work efficiency improves accordingly. Furthermore, since there is no scattering, the amount of paint is not wasted, and the amount used can be approximately the same as in the case of hand painting using a brush or roller. Further, since the brush portion 20 is brought into sliding contact with the coating material 22, the coating material directly applied by the spray from the nozzle 3 and the coating material applied by the brush portion 20 are smoothed in order. Therefore, the paint becomes uniform and the quality of the coated surface is improved.

Further, since the paint is applied not only by spraying but also by the brush portion 20, for example, where the paint does not reach by spraying only, such as a complicated structure portion such as a bolt on the coated object 22, or the brush portion. It is possible to sufficiently apply the paint to places where the paint does not reach with 20 alone, and while maintaining the paint application performance by spraying, that is, several times more work than hand painting with a brush or roller. The property can be ensured and the paintability by the brush can be added.

In the above embodiment, the guide tube 10
Although the outer shape of the above is formed into a substantially trapezoidal shape, the shape is not necessarily limited to this, and may be appropriately changed, for example, formed into a conical shape. Further, the connection with the coating gun G is not limited to the above, and any connecting means may be adopted. Furthermore, in the above-described embodiment, the paint gun G is a type that sprays the paint by pumping the external pump 6. However, for example, it may be mounted on a paint gun that sprays the paint by air, and all types of spray guns Of course, it can be applied to a mold painting gun.

[0019]

As described above, according to the coating gun applicator of the present invention, it is possible to prevent the coating material from scattering outside the guide tube and the brush portion. Therefore, the paint is less likely to be sucked into the human body, and the influence on the health of the worker can be suppressed. In addition, it is possible to prevent a situation where it adheres to an object other than a coated object, and moreover, it is not necessary to cover the periphery with a sheet or the like, which improves workability. Furthermore, since the paint that does not scatter and that is absorbed in the brush part can be applied to the coated object, it is easy to obtain the required coating film. Therefore, it is necessary to repeatedly reciprocate the coating gun with respect to the coated object as in the past. Without it, the work efficiency improves. Furthermore, since there is no scattering, the use efficiency of the paint can be greatly improved without wasting the paint.
In addition, since the brush part can be brought into sliding contact with the object to be coated, it is possible to smooth out the paint directly attached by the jet from the nozzle and the paint applied by the brush part, and therefore improve the quality of the coated surface by making the paint uniform. Can be planned. Also, since the paintability of the brush can be added while maintaining the coating performance of the paint by spraying, the paint cannot reach the place where spraying alone, such as complex structure parts, or the paint can be removed only by the brush part. Where you can't reach
It has various effects such as sufficient application of paint.
