Description

Painting device {Painting device}

One aspect of the present invention relates to a coating apparatus, and more specifically, to a coating apparatus capable of performing painting while moving along the outer wall of a building.

In recent years, high-rise buildings or apartments are increasing not only in Korea but also overseas, and the exterior wall paint construction and painting of buildings is acting as a very important factor in terms of economy and urban aesthetics. With respect to the spray painting work, the painting work of the outer walls of high-rise buildings and large ships is generally performed in a manner in which a worker hangs in the air on a rope.

However, such a work method has a clear limitation in that it is difficult to improve work efficiency because the supply and demand of skilled manpower is limited, the cost is large due to labor costs, and safety accidents such as a fall risk may occur during work.

In the recent revision of the Enforcement Decree and the Enforcement Regulations of the Air Conservation Act, details on the exterior painting work of apartment houses at workplaces generating fugitive dust have been added, and from January 1, 2021, when the rooftop waterproofing and exterior painting in apartments, conventional spraying is used. The work is impossible, and the work must be carried out in a roller method or brushing method that does not generate a lot of scattering dust.

In order to paint using the existing spray method, it is essential to install a dust barrier or apply a new dust collector, so work costs and necessary facilities are expected to increase. It seems that there will be problems such as an increase in overall cost, such as a decrease in work efficiency and an increase in working hours while remaining as it is.As a result, it is possible to meet the standards of the revised Air Conservation Act while painting is carried out in an automated or mechanized method in place of manpower. There is a need to develop a new coating method.

The length of the paint supply hose 11 is not limited, and may be adjusted according to the height of the building to be painted. For example, the paint supply hose 11 is connected via a paint tank and rollers installed on the roof of the building to be painted, and the paint supply hose 11 is wound or unwound from the roller as the painting device 1 moves. Connect the paint tank and the painting device (1).

Since the paint supply hose 11 is provided by connecting the exterior and the painting device 1, the painting device 1 may not fall to the ground during painting.

One or more painting nozzles 54 coupled to the painting nozzle connection hose 53 may be provided at regular intervals to form a painting with uniform quality.

When the coating nozzle 54 is provided as one, if the spraying amount of the paint increases by increasing the pressure of the supplied paint, the distance between the painting nozzle 54 and the wall should be increased. There is a problem that the amount of occurrence increases. Since two or more painting nozzles 54 are provided, the distance between the painting nozzle 54 and the wall can be made close even under the same spraying amount and pressure condition of the paint, thereby reducing the generation amount of scattered dust.

Although the direction of the painting nozzle 54 is not limited, it is recommended to spray the paint in a direction perpendicular or close to the surface of the wall to be painted, and spray the paint according to the shape, structure and presence or absence of irregularities of the wall.

The painting nozzle assembly 50 is preferably provided in one or more of the main body 10, and may be provided, including different painting nozzles 54. Hereinafter, as an example of the present invention, a coating apparatus 1 including three different types of coating nozzle assemblies 50 as shown in FIG. 4 will be described in detail.

Each painting nozzle assembly 50 has a different type and shape of the painting nozzle 54, and accordingly, each painting nozzle assembly 50 may have different functions and purposes.

The first painting nozzle assembly 50 includes a painting nozzle 54 for general painting, and the second painting nozzle assembly 50 includes a painting nozzle 54 for painting in narrow or corner areas. And, the third painting nozzle assembly 50 includes a painting nozzle 54 for use when the spraying direction of the paint is limited, including the uneven or indentation of the wall to be painted.

The first painting nozzle, which is the painting nozzle 54 of the first painting nozzle assembly 50 shown in Fig. 4-a, can form a wide painting surface on a wall of a general structure, and has excellent work efficiency due to a large area to be painted. . The first coating nozzle is provided at regular intervals and is provided in a vertical direction on the surface of the wall, so that the paint can be sprayed in a vertical direction on the surface of the wall.

The second painting nozzle, which is the painting nozzle 54 of the second painting nozzle assembly 50 shown in FIG. A surface may be formed, and a nozzle having a narrower spray angle than the first coating nozzle may be used as the second coating nozzle.

The second painting nozzle is provided in a vertical direction on the surface of the wall, so that the paint can be sprayed in a vertical direction on the surface of the wall. Since the spraying area of the second painting nozzle can be formed smaller than the spraying area of the first painting nozzle, the gap between the second painting nozzles can be formed narrower than the gap between the first painting nozzles, and a larger number of the second painting nozzles can be formed. A painting nozzle may be provided.

The third painting nozzle, which is a painting nozzle of the third painting nozzle assembly 50 shown in FIG. 4-c, can be used for painting a wall having an uneven or indented portion, and is provided on the side of the uneven or indented portion of the wall. And the spraying direction of the paint may be adjusted for painting the unpainted surface by the paint sprayed in the vertical direction of the wall surface by the second painting nozzle assembly 50.

The spraying direction of the paint can be made by a spraying direction adjusting means that can change the angle or spraying direction of the third painting nozzle, and as an example of the spraying direction adjusting means, it extends from the painting nozzle connection hose 53 and extends to the third painting nozzle. A flexible pipe may be used as the coating nozzle hose 58 to which this is coupled. The flexible pipe allows the position and direction of the third coating nozzle to be adjusted, and is fixed in a deformed form by an external force to perform painting.

The shape of the 3rd coating nozzle is not fixed and can be transformed into different positions and angles depending on the wall condition each time it is used, and the position of the 3rd coating nozzle is accurately recorded, and the distance between the 3rd coating nozzles is constantly adjusted. In order to perform painting of a certain quality, the third painting nozzle 54 may be provided with an indicator needle 55 indicating the spraying direction, and a scale display portion 56 with a scale for grasping the position of the indicator needle 55 ) Is preferably provided in the third coating nozzle assembly 50.

The propulsion means is a means for generating a propulsive force for attaching the main body 10 to the wall by generating a propulsive force, and the coating device 1 is not separated from the wall by the propulsive force and can stably move the wall surface while maintaining a balance.

The propulsion means is not limited, but a propulsion device 20 capable of applying a propulsive force to the main body 10 by generating wind is preferred, and as an example of the propulsion device 20, the device is It can cancel the received gravity or play a role of improving the friction between the device and the wall by being in close contact with the wall, and a propulsion device 20 that allows the device to move three-dimensionally in space may be used.

The wind generation method of the propulsion device 20 is not limited, and a means within a range that can be employed by a person skilled in the art may be used as long as it is a means capable of generating wind in a certain direction, and an embodiment of the present invention uses wind power. As a means of generating, a motor or propeller blades 22 or fans rotated by the power of an internal combustion engine are used.

One or more propulsion devices 20 may be provided, and various sizes, shapes, and numbers of propulsion devices 20 may be selected according to the size and weight of the painting device 1. When two or more propulsion devices 20 are used, it is preferable that the propulsion device 20 is provided in a symmetrical shape for the balance of the wind power provided to the painting device 1, and the center of gravity of the painting device 1 The propulsion device 20 may be provided in the modified position according to the. The propulsion device 20 may be provided with 2 to 16, and preferably 2 to 10 may be provided.

The position of the propulsion device 20 is not limited, and may be provided inside the body 10, may be provided to protrude to the outside of the body 10, and provided both inside and outside the body 10 It is also possible, it is also possible to be provided connected to the dust collecting device 40 coupled to the main body 10. When the propulsion device 20 is provided outside the main body 10, vibration may occur depending on the distance from the main body 10, so the support is supported at the connection part connecting the propulsion device 20 and the main body 10 for a stable connection. Or, it is better to have a bracket.

When the propulsion device 20 protrudes to the outside of the main body 10, the length, shape, and angle of the connection portion are not limited, but may be provided to be parallel to the wall or away from the wall, and the distance between the wall and the propulsion device 20 is When the connecting rod is provided farther away, when the driving force is generated, the distance from the side surface is increased, so that there is little dust generation, and there is an advantage in the air flow.

In addition, when the direction of the propulsion force generated by the propulsion device 20 is the first propulsion direction, all propulsion devices 20 can generate propulsion in the same first propulsion direction, and different propulsion devices 20 The propulsion device 20 may further include a propulsion device 20 that generates propulsion in a second propulsion direction different from the first propulsion direction by providing different directions of the propulsion force generated by the propulsion force. In this case, the direction of the driving force in which the magnitude of the resultant force of the driving force having the same driving direction is greater is defined as the first propulsion direction, and the direction of the driving force in which the magnitude of the total resultant force is small is defined as the second driving direction.

The first propulsion direction is generated in a direction opposite to the direction of the wind generated by the propulsion device 20 according to the mechanical law, and the angle formed by the first propulsion direction with the wall surface may be 80 degrees to 90 degrees, preferably 83 It is good that it is degrees to 87 degrees, more preferably 84 degrees to 86 degrees.

The angle between the second propulsion direction and the wall surface is preferably 75 degrees to 85 degrees, more preferably 77 degrees to 83 degrees.

If the angle between the second propulsion direction and the wall is less than the range, the adhesion resistance to the wall increases and the adhesion may decrease. If it is greater than the range, the weight of the painting device 1 is canceled by offsetting gravity. There is a problem that the effect is not sufficient.

The driving force generated by the propulsion device 20 is the x-axis with respect to the x-axis parallel to the wall of the wall for painting and the y-axis perpendicular to the wall when the painting device 1 attached to the wall is observed from the side. It can be expressed as the sum of the force acting in the direction and the force acting in the y-axis direction, and the propulsive force generated in the second propulsion direction is more than the propulsive force generated in the first propulsion direction in order to offset the gravity. It is better to have a higher proportion of the force acting on it.

In the case of generating propulsion including the component in the direction of gravity, the gravity caused by the load of the coating device 1 is canceled, and when the component in the direction toward the wall is included, the painting device 1 can be brought into close contact with the wall. In addition, since the normal force on the contact surface increases and the frictional force increases, there is an advantage that the coating device 1 can be well attached to the wall.

In addition, the propulsion device 20 can be rotated so that the direction of the wind power can be changed in real time, and the angle formed by the propulsion direction with the wall surface can be changed. The propulsion device 20 may be provided in a controllable form to change the direction of the propulsion force by an external signal.

According to an embodiment of the present invention, when the propeller blades 22 rotated by the motor as the propulsion device 20 are used, the propulsion motor 21 is light in weight, less failure, and high output. Also, it is preferable that an internal combustion engine or a motor that is easy to control output is used, and the type of the propulsion device 20 is not limited. As an example (實例), the propulsion motor 21 may be a motor supplied with DC or AC power, a brush motor or a brushless motor may be used depending on the structure of the motor, and a brushless motor may be used. In this case, an in-runner type or an out-runner type motor may be used depending on the positional relationship between the stator and the rotor.

When an in-runner type motor is used, the rotor is provided inside, which is advantageous for instantaneous high-speed output, and when an out-runner type motor equipped with an external rotor is used, it is advantageous in dissipating heat and generating strong torque. There is an advantage to be able to.

In this case, an electronic speed controller (ESC) 120 may be further included in order to control the output by adjusting the number of rotations of the motor.

The electronic transmission 120 is connected to the propulsion motor 21, the power supply and the control unit 100, and can control the output and rotation speed of the motor by adjusting the voltage or frequency supplied to the propulsion motor 21, and transfer from the outside. It is preferable to be able to control the propulsion force generated by controlling the output and rotation speed of the propulsion motor 21 by the signal.

The conveying means 30 is a means for allowing the painting device 1 to move the wall, and the painting device 1 moves the main body 10 located on the wall of the wall by the propulsion device 20 along the wall surface. It may include a moving wheel and a caterpillar combined with the moving wheel as a conveying means.

The driving wheel 31 is a wheel that is connected to the driving motor 130 provided in the main body and is driven to provide force to move the track, and the rotation direction and rotation speed of the driving wheel 31 are controlled by the driving motor 130. Regulated by

The caterpillar 32 generally refers to a device in which a belt made of steel plate or the like is hung around a wheel, etc., and is coupled to surround the driving wheel 31 on the outer circumferential surface of the driving wheel 31, and the driving wheel 31 ) Is combined with the inner surface of the caterpillar 32, and the caterpillar 32 moves along the outer circumferential surface of the moving wheel according to the rotational speed and direction of the moving wheel 31. The caterpillar is supported and provided by wheels other than the driving wheels 31 on the inner surface.

In order to completely transmit the rotational motion of the movable wheel 31 and prevent slipping between the movable wheel 31 and the caterpillar 32, a protrusion is provided on the outer circumferential surface of which the movable wheel 31 is coupled to the caterpillar or It has a shape structure, and includes a recess or a groove formed on the inner surface of the caterpillar 32 so as to be engaged with the outer circumferential surface structure of the driving wheel 31 so as to be coupled. Two moving wheels 31 may be present in the front and rear of the coating apparatus, but it is preferable to exist as one in the front or rear of the coating apparatus because the weight of the coating apparatus can be reduced.

The caterpillar 32 coupled to the driving wheel 31 provides friction with the wall to enable stable wall attachment of the painting device, and allows the painting device to cross or pass unevenness or obstacles existing on the wall. Make sure that the device does not deviate from the wall and provides a uniform coating.

The material of the caterpillar 32 is not limited, and it is preferable to use a material having a long life due to excellent abrasion resistance while having excellent friction with the wall surface, and preferably a soft polymer having a shore hardness in the range of 50 to 90 may be used. .

The drive device 30 according to an embodiment of the present invention includes a caterpillar 32 and a driving wheel 31. The driving device 30 is provided symmetrically on both sides of the main body 10, respectively.

It is preferable that the caterpillar 32 is formed with irregularities in order to improve the frictional force on the outer surface in contact with the wall. If one of the wheels supporting the caterpillar 32 is provided, a driving wheel is provided at the front or rear of the main body, and when a driving wheel 31 is provided at the rear of the coating device, the corresponding The front wheel 33 may be provided instead of the driving wheel 31.

Unlike the driving wheel 31, the floating wheel 33 is a wheel that does not transmit power but does not directly contact the floor, and is preferably provided in the front opposite to the driving wheel 31.

The bogie wheel 34 is provided inside the caterpillar 32 and directly contacts the wall through the track, and one or more may be additionally included. The bogie wheel 34 stably maintains the shape and movement of the track to aid in the movement of a stable device and to form a uniform coating.

In order for the painting device 1 to perform painting work with a certain quality, it is preferable that the distance between the wall surface and the painting nozzle 54 of the painting nozzle assembly 50 be kept constant. For example, when the coating device 1 moves past a wall surface with a protrusion, the distance between the wall surface and the painting nozzle 54 may increase as it passes through the protrusion, and only one endless track passes through the protrusion. Thus, when the main body 10 is not disposed parallel to the wall surface, the distance between each painting nozzle and the wall surface may be different, so that the painting result may be obtained unevenly.

In this way, in order to solve the problem that the quality of the painting may be poor because the distance between the painting nozzle 54 and the wall surface is not kept constant, the painting apparatus according to an embodiment of the present invention is provided with a distance between the painting nozzle 54 and the side surface. It may include a height adjustment means capable of changing the position and shape of the driving wheel 31 or the caterpillar 32 to maintain the.

The distance between the main body and the wall may be adjusted by controlling the driving wheel 31 and the caterpillar 32 coupled thereto by a height adjusting means. As an example, the height adjustment means is not driven by being directly coupled with a driving wheel and a caterpillar under normal conditions, but operates when a signal for controlling the height of the coating apparatus is received from the control unit 101 to contact the caterpillar, It may include a height adjustment wheel to change the shape or path of the caterpillar.

The height adjustment means may be involved in the movement of a caterpillar or a moving wheel according to a signal transmitted from the control unit 101 to increase or close the distance or distance between the painting device and the wall surface. The coating device can perform uniform coating even on irregular or uneven walls.

The configuration of the height adjustment means is not limited by the examples described in the present specification, and is interpreted as including structures and devices that can be employed by a person skilled in the art in order to obtain the same effect.

The signal transmitted to the height adjusting means is generated from a gap measuring sensor included in the painting apparatus 1, processed through the control unit 101, and then transmitted to the height adjusting means.

As an example, it is preferable that at least one gap measurement sensor is provided in the body, and the gap measurement sensor measures the distance between the body and the wall and transmits the measurement data to the control unit 101 in real time or at regular time intervals, and the control unit 101 processes the received data and generates a signal for controlling the height adjustment means when the interval is out of the previously input numerical range or when the difference between the measured intervals exceeds a predetermined range.
