Description

A painting device used on the wall}

The present invention relates to a wall paint painting device. In order to solve problems caused by the prior art, such as workers being exposed to dust when painting the interior and exterior walls of a building using a spray method, workers are not exposed to dust when painting the interior and exterior walls of a building. This relates to a wall paint painting device in which a roller-type or plate-based painting unit is combined with an attachment robot body.

The total number of deaths from industrial accidents in the construction industry has remained in the 2,000 range since exceeding 2,000 from 1,864 in 2012 to 2,142 in 2018, and the number of deaths from disasters each year is also approaching 1,000. In particular, the proportion of deaths from industrial accidents in the construction industry is 49.9% (482 out of 966), and the proportion of fatalities from falls is an overwhelming 77.1% (290 out of 376).

In painting the interior and exterior walls of buildings, external rope workers who can paint the interior and exterior walls of buildings are always suffering from a manpower shortage due to safety issues involving the risk of falling and the need for a long period of experience to acquire a certain level of work skill. If unskilled or foreign workers are hired due to manpower supply and demand issues, the number of industrial accidents such as falls is expected to increase due to lack of skills.

Accordingly, there is a trend of change in the construction industry that prevents accidents that occur due to labor input by having machines replace people with painting the interior and exterior walls of high-rise buildings. However, for work that requires precision or construction work that requires inspection, machines replace people. As it is not easily converted into a work process, development of related technology is urgently needed.

In relation to painting work on interior and exterior walls of buildings, spray-type painting robots using multiple spray nozzles for painting have recently been on the rise.

Robotic painting based on the spray method is an advantageous method for companies performing painting work because it is fast and has little burden on additional costs, and the quality of the painting is generally good, so it is widely applied to painting work on the interior and exterior walls of buildings.

Let's look at Korean Patent Publication No. 10-2012-0109959, which is a related prior art.

The prior art relates to a building exterior wall painting device using a multi-spray method that is installed on the exterior wall of a high-rise building and automatically moves vertically or horizontally and can automatically paint the exterior wall of the building using a multiple spray method.

However, due to the problem of dust caused by the spraying method of the prior art, the recently revised domestic Air Quality Conservation Act has been revised to allow painting work only by the roller method or low-flying dust generation method when painting outdoors. The enforcement regulations will be further revised and come into effect in 2023.

In particular, spray painting is prohibited in most overseas countries due to environmental issues. Accordingly, there is an urgent need for technological development in Korea to respond to this.

In order to solve the problems caused by the above-described prior art, we propose a wall paint painting device that can be combined with a paint part that does not generate dust and a painting robot device that can move while attached to the inside and outside walls of a building during painting work on the inside and outside walls of the building. I want to do it.

In order to solve the problems caused by the above-described prior art, the wall paint coating device according to the present invention includes an attachment robot body (100) that is attached to the wall and moves by the operation of the air chamber (120) in a state in which the air chamber (120) is mounted. ); and a painting unit 200 coupled to the attachment robot main body 100, and the shape of the painting unit 200 may be a roller type or a plate shape.

Preferably, a paint supply pipe 250 connected to the painting unit 200; And it further includes a soleroid valve 300 mounted on one side of the paint supply pipe 250,

The paint supplied by the operation of the pump flows to the painting unit 200 through the paint supply pipe 250, and only when the attachment robot body 100 moves, the soleroid valve 300 opens and flows into the pump. The supplied paint may flow into the painting unit 200.

Preferably, the painting unit 200 includes a paint flow pipe 220 through which the paint supplied from the paint supply pipe 250 flows; And a plurality of paint discharge holes 240 formed at regular intervals in the paint flow pipe 220,

With the paint supply pipe 250 connected to both ends of the paint flow pipe 220, paint may flow into both ends of the paint flow pipe 220.

Preferably, it further includes a wheel 140 mounted on the attachment robot body 100,

The painting unit 200 further includes a roller-type brush 260 surrounding the paint flow pipe 220,

In a state where the paint flow pipe 220 is fixedly coupled to the attachment robot body 100 and the roller-type brush 260 surrounds the paint flow pipe 220, the paint flow pipe 220 is operated by the motor included in the air chamber 120. As the gap between the attachment robot body 100 attached to the wall and the wall becomes narrower, the degree of adhesion of the roller-type brush 260 to the wall can increase.

Preferably, it further includes a wheel 140 mounted on the attachment robot body 100,

The painting unit 200 includes a painting plate 280 coupled to the paint flow pipe 220; And it further includes a plate-shaped brush 290 surrounding the painting plate 280,

The painting plate 280 has a rectangular shape with a certain area,

A plurality of paint plate discharge holes 282 are formed at regular intervals on the surface of the paint plate 280 facing the wall, and the paint plate discharge holes 282 are formed at regular intervals up, down, left and right on the entire surface of the paint plate 280 facing the wall. A plurality of paint plate discharge holes 282 are formed,

In a state where the paint flow pipes 220 are composed of two or more across the painting plate 280, the two or more paint flow pipes 220 are coupled to the painting plate 280 at regular intervals from each other to apply the painting. Supporting the plate 280, at least two of the two or more paint flow pipes 220 are coupled to each other off the center of the painting plate 280 to support the painting plate 280. And

In a state where the paint flow pipe 220 is fixedly coupled to the attachment robot body 100 and the plate-shaped brush 290 surrounds the painting plate 280, the wall surface is moved by operation of the motor included in the air chamber 120. As the close contact gap between the attachment robot body 100 attached to the wall surface narrows, the degree of close contact of the plate-shaped brush 290 with the wall surface may increase.

Due to the above-mentioned problem solving means, the roller-type or plate-shaped painting part is coupled to the attachment robot body attached to the interior and exterior walls of the building through the operation of the air chamber, and the paint is supplied only when the attachment robot body is moved, and further included in the air chamber. The operation of the motor increases the adhesion of the roller-type brush or plate-type brush that is in close contact with the wall, and the strength of the paint coating can be adjusted, thereby solving problems caused by painting the interior and exterior walls of a building according to the prior art.

Hereinafter, preferred embodiments of the method according to the present invention will be described with reference to the attached drawings. In this process, the thickness of lines or sizes of components shown in the drawing may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are terms defined in consideration of functions in the present invention, and may vary depending on the intention or custom of the user or operator. Therefore, definitions of these terms should be made based on the content throughout this specification.

Description will be made with reference to FIGS. 1 to 3.

The wall paint painting device according to the present invention includes an attachment robot body 100, a painting unit 200, a paint supply pipe 250, a soleroid valve 300, a pump, and a paint storage container.

As the attachment robot body 100 moves along the wall, the painting unit 200 coupled thereto comes into close contact with the wall, thereby performing a paint painting operation on the wall. The paint supply pipe 250 is connected to the painting unit 200, and the paint flowing through the paint supply pipe 250 is supplied to the painting unit 200.

With one end of the paint supply pipe 250 connected to a pump fixed at a certain location and the other end connected to the attachment robot body 100, the paint supply pipe 250 remains in communication even when the attachment robot body 100 moves along the wall. It can be formed to a considerable length that can follow the attachment robot main body 100, and of course, it can also be freely movable.

By operating the pump, paint is supplied from the paint storage container to the paint supply pipe 250.

In order to prevent the problem of uneven paint coating as the paint is continuously supplied and the wall painting work is performed while the attachment robot main body 100 is stopped, and furthermore, the problem of excess paint being supplied unnecessarily and being wasted, the paint A soleroid valve 300 may be installed on one side of the supply pipe 250.

As the paint supplied by the operation of the pump flows through the paint supply pipe 250 and is supplied to the painting unit 200, the paint may be supplied only when the attachment robot body 100 moves. Paint is supplied only when the attachment robot body 100 moves, thereby achieving uniform painting and minimizing paint waste.

Control of the attachment robot body 100 can be performed through an MCU (Micro Computer Unit) mounted on the attachment robot body 100 from the GCS (Ground Control System) on the ground, and the operation of the soleroid valve 300 is also performed on the ground. Of course, this can be done under the control of GCS (Ground Control System).

The attachment robot body 100 is equipped with an air chamber 120, and the pressure between the attachment robot body 100 and the wall is maintained at a state lower than atmospheric pressure by operating the motor included in the air chamber 120. The attachment robot body 100 is moved along the wall while attached to the wall.

By operating the motor included in the air chamber 120, the degree of adhesion between the attachment robot body 100 and the wall can be adjusted to increase or decrease the adhesion between the painted part 200 and the wall. This will be described later.

As a means of moving the attachment robot body 100, wheels 140 may be mounted on the attachment robot body 100. The rotation of the wheel 140 is also controlled by the ground control system (GCS), and the moving speed of the attachment robot body 100 can be adjusted accordingly. Furthermore, the direction in which the attachment robot body 100 moves can be determined by adjusting the rotation speed of one wheel 140 and the rotation speed of the other wheel 140.

The degree of wall painting can be adjusted by adjusting the rotation speed of the wheel 140. In other words, the moving speed of the attachment robot body 100 is determined according to the rotation speed of the wheel 140. At a slow speed, a relatively large amount of paint will be painted on the wall, and at a high speed, a relatively small amount of paint will be applied to the wall. Since it will be painted on the wall, the degree to which the paint is applied to the wall may vary depending on whether it is moved at a fast or slow speed.

The painting unit 200 may be coupled to the attachment robot body 100 in a fixed state. Accordingly, the degree of adhesion between the painting unit 200 and the wall or the amount of paint to be applied varies depending on the moving speed of the attachment robot main body 100 or the degree of adhesion to the wall. Ultimately, the moving speed of the attachment robot main body 100 or the air chamber ( 120), the degree of painting can be adjusted by adjusting the number of revolutions of the motor included.

The painting unit 200 may include a paint flow pipe 220 through which paint supplied from the paint supply pipe 250 flows and a plurality of paint discharge holes 240 formed in the paint flow pipe 220.

A plurality of paint discharge holes 240 may be formed in the paint flow pipe 220 at regular intervals from each other. Ultimately, the paint discharged through the paint discharge hole 240 is painted on the wall through a roller-type brush 260 or a plate-type brush 290, which will be described later. As the paint discharge holes 240 are formed at regular intervals, the paint part (200) The paint can be discharged and painted evenly on the entire wall to which it is in close contact.

The paint supply pipe 250 is connected to both ends of the paint flow pipe 220, and in this state, paint may flow into both ends of the paint flow pipe 220.

When paint flows in from only one end rather than both ends, a large amount of paint is discharged to the paint discharge hole 240 close to the inflow end, and to the paint discharge hole 240 located far from the inflow end. A small amount of paint may be discharged, and accordingly, even when the entire painted part 200 is in close contact with the wall, the degree of painting for each part in close contact may vary, resulting in uneven paint application.

Therefore, it is preferable that the paint flows into both ends of the paint flow pipe 220 so that paint can be applied as uniformly as possible.

The shape of the painting unit 200 may be roller-type or plate-shaped.

The roller-type painting unit 200 will be described with reference to FIG. 2 .

In addition to the paint flow pipe 220 and the paint discharge hole 240 described above, the painting unit 200 may further include a roller-type brush 260 surrounding the paint flow pipe 220.

The roller-type brush 260 surrounds the paint flow pipe 220, which moves as the attachment robot body 100 moves, and is rotated and moved by the movement of the paint flow pipe 220, and is in close contact with the wall, and the paint flow pipe 220 The paint discharged through the paint discharge hole 240 is applied to the wall through this roller-type brush 260.

Since the roller-type painting unit 200 is in close contact with the wall and the paint is applied, the problem caused by the conventional spray painting process that generates dust is solved.

In a state where the paint flow pipe 220 is fixedly coupled to the attachment robot body 100 and the roller-type brush 260 surrounds the paint flow pipe 220, the attachment is attached to the wall by the operation of the motor included in the air chamber 120. As the gap between the lower end of the robot body 100 and the wall becomes narrower, the degree of adhesion of the roller-type brush 260 to the wall can increase.

That is, as the adhesion of the attachment robot main body 100 increases due to the operation of the motor included in the air chamber 120, the roller-type painting unit 200 fixedly coupled to the attachment robot main body 100 also increases the adhesion to the wall surface. is further increased, and thus the degree of paint applied to the wall can be adjusted.

Ultimately, the degree of paint applied to the wall can be adjusted by the rotation speed of the wheel 140 or the adhesion force of the attachment robot body 100 by the operation of the air chamber 120.

The plate-shaped painting unit 200 will be described with reference to FIG. 3 .

In addition to the paint flow pipe 220 and the paint discharge hole 240 described above, the painting unit 200 includes a plate-shaped painting plate 280 coupled to the paint flow pipe 220 and a plate-shaped brush surrounding the painting plate 280 ( 290) may further be included.

The paint plate 280 may have a rectangular shape with a constant area.

As the attachment robot body 100 moves, the paint flow pipe 220 moves. As the paint flow pipe 220 moves, the painting plate 280 of a certain area moves along the wall. At this time, if the painting plate 280 is not sufficiently supported by the paint flow pipe 220, the painting plate 280 of a certain area may be moved in an unexpected direction during the process of moving along the wall, or damage may occur during the movement process.

As the paint flow pipe 220 is coupled to the painting plate 280, the part coupled to the paint flow pipe 220 corresponds to a portion of the painting plate 280, thereby preventing the entire painting plate 280 from being supported, thereby causing the above-described problem. In order to prevent this, the paint flow pipes 220 may be composed of two or more paint flow pipes 220 crossing the painting plate 280. In this state, two or more paint flow pipes 220 are connected to the painting plate 280 at regular intervals from each other. It can be combined to support the painting plate 280.

A plurality of paint discharge holes 282 may be formed at regular intervals on the surface of the paint plate 280 facing the wall. The paint discharged through the paint flow pipe 220 to the paint discharge hole 240 reaches the painting plate 280 and is discharged to the plurality of painting plate discharge holes 282 formed in the painting plate 280, and is discharged through the painting plate discharge hole. The paint discharged through 282 is applied to the wall via a plate-shaped brush 290.

As the paint plate discharge holes 282 are formed at regular intervals, the paint discharged through the paint plate discharge holes 282 flows uniformly to the plate brush 290, and thus the entire plate brush 290 is brought into close contact. The paint can be discharged and applied evenly to the entire wall surface.

The plate-shaped brush 290 surrounds the painting plate 280 mounted on the paint flow pipe 220, which moves as the attachment robot body 100 moves, and the plate-shaped brush 290 moves due to the movement of the paint flow pipe 220. The paint comes into close contact with the wall surface, and the paint discharged through the paint flow pipe 220 to the paint discharge hole 240 is painted on the wall surface through the painting plate 280 and the plate-shaped brush 290.

Since the plate-shaped painting part 200 is in close contact with the wall and the paint is applied, the problems caused by the conventional spray painting work that generates dust are solved.

With the paint flow pipe 220 fixedly coupled to the attachment robot body 100 and the plate-shaped brush 290 surrounding the painting plate 280, the attachment robot is attached to the wall by operating the motor included in the air chamber 120. As the gap between the bottom surface of the main body 100 and the wall narrows, the degree of adhesion of the plate brush 290 to the wall may increase.

That is, as the adhesion of the attachment robot main body 100 increases due to the operation of the motor included in the air chamber 120, the adhesion of the plate-shaped painted part 200 fixedly coupled to the attachment robot main body 100 to the wall also increases. This increases further, and the degree of paint applied to the wall can be adjusted accordingly.

Ultimately, the degree of paint applied to the wall can be adjusted by the rotation speed of the wheel 140 or the adhesion force of the attachment robot body 100 by the operation of the air chamber 120.

Above, the present invention has been described with reference to the embodiments shown in the drawings so that those skilled in the art can easily understand and reproduce the present invention, but these are merely illustrative examples, and various modifications and equivalent alternatives can be made by those skilled in the art from the embodiments of the present invention.
