Description

Operating device for spray gun}

The present invention relates to a spray gun operating device capable of remotely operating a spray gun used for painting various structures. The present invention relates to a spray gun operating device capable of obtaining a uniform painting quality by maintaining a certain distance between the spray gun and the surface to be painted as well as being able to paint the painted surface very simply without auxiliary tools such as ladders.

As is well known, it is common to paint the interior and exterior surfaces of various structures such as buildings with paints or paints for corrosion prevention and aesthetics. Such a painting operation includes a method of directly applying paint to the surface to be coated with a brush or roller, and a method of spraying the paint in the form of particles on the surface to be coated using an air or airless spray gun.

Among them, the spray method is mainly used when the surface to be painted is relatively wide, such as an exterior wall or ceiling of a building, due to the advantages of being able to paint very easily and quickly.

The spray gun is configured in the form of a pistol with a nozzle at the ejection port, and is connected to the air compressor and the paint tank with a hose, and the operator pulls the trigger with a finger while holding the handle of the spray gun to easily apply paint to the surface to be painted. Can be sprayed.

However, since most of the painting work using a spray gun is performed manually by a worker, the following problems have been encountered.

First, in the case of the area where the surface to be painted is roughly opposite the height of the worker, it is relatively easy to spray paint and paint, but it is not only very difficult to paint the surface to be painted at a high position such as the ceiling or the upper side of the wall, but also the uniform coating quality. It is also quite difficult to obtain.

In other words, in order to spray the paint on the ceiling or the upper side of the wall, the operator must tilt the head back and raise the hand holding the spray gun high above the head to spray the paint, so the painting work is inevitably difficult. Also, the work efficiency is easily fatigued. Not only is it greatly degraded, but it is difficult to obtain good coating quality due to the spraying in an unstable position

Second, accordingly, the paint is sprayed in a state close to the ceiling using, for example, a ladder, but even in this case, the posture is still unstable, so it is difficult to obtain good coating quality, fatigue is easily felt, and a fall accident occurs. There was also a lot of fear of becoming.

Third, in the case of painting using a spray gun, the distance between the surface to be painted and the spray gun has a very large effect on the painting quality, but manual work by the operator cannot maintain a constant distance between the two, so uniform and good painting quality cannot be obtained.

Fourth, it is difficult to grasp it because the worker is close to the surface to be painted even though the painting quality is uneven due to partially sprayed or less sprayed paint due to an unstable posture during painting on the ceiling or the upper side of the wall.

It is possible to obtain a much more uniform coating quality compared to the conventional one.

In addition, when spraying paint on the ceiling or the upper side of the wall, the worker proceeds the painting in a state that is sufficiently far from the surface to be painted, so that the uneven painting condition such as stains due to the difference in the amount of paint applied to the surface to be painted is more easily corrected. Because it can be recognized, it is also possible to prevent coating defects in advance.

Therefore, the present invention has a very excellent effect that greatly contributes to improvement of work convenience, reliability, safety, and quality of painting using a spray gun.
