In addition, the bracket 140 may be provided as an endless winder, so that the frame 140 may be moved in the vertical directions D3 and D4.

The applicator 130 may be movable along the left and right directions (D1, D2) within the inner space provided by the frame 110, and is a kind of spray nozzle for directly spraying the paint onto the target surface SF. It may include.

When the wire WR is connected to the bracket 140 and maintains a certain length, the frame 110 is positioned at a predetermined position along the vertical direction (D3, D4). In this case, the application unit The 130 moves along the left and right directions D1 and D2 within a range along the left and right directions D1 and D2 of the frame 110 and sprays the paint onto the target surface SF.

When spraying is complete, the length of the wire WR is changed by the driving force of the winch drum DR, and the frame 110 is in a vertical direction ( It moves to D3, D4), and is located in another predetermined position. After that, spraying of the paint by the application unit 130 is performed.

When a certain area is applied along the vertical directions D3 and D4 of the target surface SF as described above, the winch drum DR is moved along the left and right directions D1 and D2. Accordingly, the frame 110 is also moved along the left and right directions D1 and D2.

When the frame 110 moves along the left and right directions D1 and D2, the frame 110 moves in the vertical direction (D3, D4) according to the length change of the wire WR, which is the above-described method, and the application part The application of the target surface SF is completed by moving along the left and right directions D1 and D2 in the frame 110 of 130 and spraying the paint by the application unit 130.

On the other hand, the frame 110 covers the applicator 130 to protect the applicator 130, the upper frame 112, the lower frame 114, the left frame 116 and the right frame 118, etc. It may include.

The frame 110 may have a rectangular parallelepiped shape as a whole due to the upper frame 112, the lower frame 114, the left frame 116, and the right frame 118, but is not limited thereto. It can be changed into various shapes such as the open semi-cylindrical shape.

On the other hand, the frame 110 supports the movement of the applicator 130 in the left and right directions (D1, D2) and supports the movement in the left and right direction support rails 111 and the forward and backward directions (D5, D6). It may include a support rail (not shown) in the front and rear directions for supporting and implementing.

On the other hand, the movement of the applicator 130 in the left and right directions (D1, D2) and the movement in the front and rear directions (D5, D6) is not limited to the above-described rail method, and all known moving means may be applied. I can.

The wheel part 120 guides the movement when the frame 110 moves along the wall surface W of the building ST according to the change in the length of the wire WR by the driving of the winch drum DR. As a means of doing so, it may be a component that allows the frame 110 to be in close contact with the wall surface (W).

The wheel part 120 is the target by the application part 130 by moving the position along the upper direction (D3) or the lower direction (D4) of the frame 110 due to the change in the length of the wire (WR). In the process of applying the first region R1 of the surface SF, a state in contact with the wall surface W in the first state may be maintained.

Here, the first region R1 may mean an area of a substantially flat target surface SF in which a protruding wall surface or a protruding obstacle does not exist.

In addition, the first state may refer to a state of the wheel part 120 so that the quality of application of the target surface SF requiring application is not degraded, which is the application part 130 and the target surface ( It may vary depending on the optimal distance from SF).

When the application of the first region R1 is completed by the application unit 130, the length of the wire WR is changed by the driving force of the winch drum DR, so that the frame 110 becomes the first region. It moves to the second area R2 which is the next area of (R1).

Here, as shown in FIGS. 1 and 2, the second region R2 has a wall surface protruding from the state of the wall surface of the first region R1 or an obstacle protruding from the wall surface of the first region R1. It may be an existing region, for example, a region in which the window CH formed by protruding is present.

At this time, after the application of the first region R1 is completed, the wheel part 120 is in the first state before entering the second region R2 due to a change in the length of the wire WR. As shown in FIG. 2, the second state may be withdrawn from the frame 110.

Due to the change in the state of the wheel part 120 from the first state to the second state, when the frame 110 moves in the upward direction (D3) or the downward direction (D4), the protruding Interference with the wall or the protruding obstacle may be prevented.

And, when there is an area that needs to be applied in the second area R2, the coating unit 130 is applied among the second area R2 while the wheel unit 120 is in the second state. It is possible to apply the required area, which will be described in detail with reference to FIGS. 4 to 6.

4 to 6 are schematic side views for explaining a state change of the coating apparatus according to an embodiment of the present invention when an obstacle protruding from a wall surface of a building is present.

First, referring to FIG. 4, the frame 110 is positioned on the first area R1 when the wire WR is connected to the bracket 140 and maintains a certain length. In this state, the application unit The 130 moves along the left and right directions D1 and D2 within a range along the left and right directions D1 and D2 of the frame 110 and sprays the paint onto the target surface SF.

At this time, the wheel part 120 maintains the first state and maintains a state in close contact with the wall surface W, whereby the frame 110 is stably positioned on the first region R1 without shaking, The applicator 130 may allow the first region R1 to be applied while being disposed at the first position on the frame 110.

When the application of the first region R1 is completed, the frame 110 may be moved to the second region R2 as illustrated in FIG. 5 due to a change in the length of the wire WR.

At this time, when the frame 110 moves in the downward direction D4, in order to prevent interference with a protruding wall surface or a protruding obstacle (for example, a window, etc.) existing in the second region R2, The distance from the wall surface W may be increased, and this may be implemented by drawing out the wheel part 120.

The wheel part 120 may be in a second state, which is more pulled out than the first state before the frame 110 enters the second region R2, and thus, the frame 110 ) More and more spaced apart.

The change in the state of the wheel unit 120 may be implemented by a pneumatic cylinder or a hydraulic cylinder, and other known means may be applied.

On the other hand, when there is an area in the second area R2 that requires coating by a paint (for example, the left and right portions of the window), the application unit 130 performs the application based on the first position. By moving the position toward the required area, the distance for application between the areas where the application is required can be adjusted.

Since the spray pressure of the paint sprayed by the applicator 130 is optimized in consideration of the quality of the coating and the distance to the coated surface, the applicator 130 applies the area that needs to be applied among the second area R2. In this case, as in the case of applying the first region R1, if the first region R1 is positioned at the first position, the distance from the region to be applied may increase, thereby causing a problem in the quality of the application.

For this reason, in the present invention, in the case of applying a region requiring application among the second region R2, the application unit 130 is moved toward the region where application is required, and then the paint is sprayed to prevent degradation of coating quality. It can be prevented.

Meanwhile, the applicator 130 may be implemented as a coating roller that is rotatable while absorbing the paint in addition to the spray nozzle for spraying the paint.

In this case, while the frame 110 is positioned on the second region R2, the region requiring application among the second region R2 may be applied by rotating the application roller.

In other words, the application unit 130 is implemented as a spray nozzle that directly sprays the paint toward the first region R1 in a state disposed at the first position on the frame 110, and the first region ( R1) is applied, but when the protruding wall surface or the protruding obstacle is present in the second region R2 and a region requiring application by the paint is present, the paint is applied in the second region R2. It is changed to a rotatable application roller in an absorbed state and moves toward the required region to apply the region requiring the application.

Of course, it will be possible to apply the first region R1 with an application roller.

When the application of the area in the second area R2 that needs to be applied is completed as described above, the frame 110 is next to the second area R2 as shown in FIG. 6 due to a change in the length of the wire WR. It may be moved to the third area R3, which is an area.

Since the application of the third region R3 is the same as the application of the first region R1, a detailed description will be omitted.

On the other hand, the coating device 100 according to an embodiment of the present invention is mounted on the frame 110 to detect the state of the wall surface W with respect to the direction in which the frame 110 moves. It may include (not shown), and may further include a control unit (not shown) for controlling the wheel unit 120 based on the detection result by the wall surface detection unit.

When the frame 110 moves according to a change in the length of the wire WR, the control unit may control the wheel unit 120 in real time based on a detection result by the wall surface detection unit.

Therefore, when the frame 110 is moved in the vertical direction (D3, D4) and the target surface (SF) is applied, the present invention detects a protruding wall surface or a protruding obstacle in real time, and the wheel part ( By controlling 120), it is possible to smoothly perform the coating operation without stopping the operation, while preventing interference between the frame 110 and the protruding wall.

In the above, the configuration and features of the present invention have been described based on the embodiments according to the present invention, but the present invention is not limited thereto, and it is understood that various changes or modifications can be made within the spirit and scope of the present invention. It will be apparent to those skilled in the art, and therefore, such changes or modifications should be found to fall within the scope of the appended claims.
