Meanwhile, a first shatterproof unit 140 and a second shatterproof unit 150 may be mounted on the second moving unit 130, and the first shatterproof unit 140 and the second shatterproof unit may be provided. 150 may be disposed in front of the injection unit 120 to prevent scattering of the paint sprayed through the injection unit 120.

The first scattering prevention unit 140 may absorb the paint sprayed through the spray unit 120 to prevent scattering of the paint, and may be rotated by contact with the target surface SF.

The first scattering prevention unit 140 may be located within an injection range RG of the coating material IN, which is partially sprayed through the injection unit 120, and the whole is injected through the injection unit 120 It may be located in the injection range (RG) of the paint (IN).

In other words, the first scattering prevention unit 140 may be located within an injection range RG of the coating material IN, which is at least partially sprayed through the injection unit 120.

Alternatively, the first scattering prevention unit 140 may be located outside the injection range RG of the coating material partially sprayed through the injection unit 120, and the whole is injected through the injection unit 120 It may be located outside the injection range (RG) of the paint (IN).

The first scattering prevention unit 140 may include a 1-1 scattering prevention unit 142 and a 1-2 scattering prevention unit 144 which are respectively disposed on the front upper side and the front lower side of the injection unit 120. Can.

The first-first scattering preventing unit 142 may prevent the paint sprayed from the spraying unit 120 from being scattered toward the upper direction, and the first-2 scattering preventing unit 144 may be the spraying unit It is possible to prevent the paint sprayed from 120 from being scattered toward the downward direction.

Here, the first-first scattering prevention unit 142 and the first-2 scattering prevention unit 144 are spraying spaces for the paint sprayed through the spraying unit 120 to be directly sprayed on the target surface SF. It can be arranged spaced apart, so that (S) is formed.

The first-first scattering prevention unit 142 and the first-2 scattering prevention unit 144 may be formed of a cylindrical sponge, and the mounting frame 134 by contact with the target surface SF. ).

That is, the first-first scattering prevention unit 142 and the first-2 scattering prevention unit 144 are mounted frame 134, left and right support frame 132, or the vertical direction of the injection unit 120 ( When moving to D2), that is, when moving in the vertical direction D1, D2 of the first moving unit 110, it may be rolled by contact with the target surface SF.

In other words, the first-first scattering prevention unit 142 and the first-2 scattering prevention unit 144 are interlocked with the movement of the injection unit 120 in the vertical direction (D1, D2) in the vertical direction ( D1, D2).

The first-first scattering prevention unit 142 and the first-2 scattering prevention unit 144 may have widths corresponding to the widths of the mounting frame 134 in the left and right directions D3 and D4, In other words, it may be arranged to be long along the left and right directions D3 and D4 so as to correspond to the movement ranges of the left and right directions D3 and D4 of the injection part 120 on the left and right direction support frames 132. .

Further, the first-first scattering prevention unit 142 and the first-2 scattering prevention unit 144 may be located on the mounting frame 134 so as to protrude more forward than the mounting frame 134, Conversely, the mounting frame 134, the first-first scattering prevention unit 142 and the first-2 scattering prevention unit 144 is in contact with the target surface (SF), the target surface (SF) ) And can be placed apart.

This is because the first-first scattering prevention unit 142 and the first-2 scattering prevention unit 144 are formed of a sponge and contract slightly when contacting the target surface SF, thereby causing the mounting frame 134 This is to prevent contact with the target surface SF.

Meanwhile, the first-first scattering prevention unit 142 and the first-2 scattering prevention unit 144 are rotated on the rotation support unit 135 which is installed on the left cover frame 134c and the right cover frame 134d, respectively. It can be mounted as possible.

Here, a part of the left-right direction (D3, D4) side of the 1-1 scattering prevention unit 142 and the 1-2 scattering prevention unit 144 is the left cover frame 134c and the right cover frame ( 134d) may prevent the paint sprayed through the injection unit 120 from being scattered.

And, the other part of the left-right direction (D3, D4) side of the 1-1 scattering prevention unit 142 and the 1-2 scattering prevention unit 144, that is, the left cover frame 134c and the right The front side of the cover frame 134d may be closed through a separate component, for example, a separate sponge or a separate blocking wall, or the left cover frame 134c and the right cover frame 134d It can be closed by changing the shape of, for example, changing to a "T" shape protruding toward the injection space (S).

On the other hand, the 2-1 scattering prevention unit 152 and the 2-2 scattering prevention unit 154 are connected to the injection unit 120 so that the injection unit 120 supports the left and right support frames 132. Accordingly, when moving in the left and right directions D3 and D4, it may be interlocked to move in the left and right directions D3 and D4 together with the injection unit 120.

In addition, the 2-1 scattering prevention unit 152 and the 2-2 scattering prevention unit 154 are in the left and right directions (D3, D4) of the injection unit 120 on the left and right support frames 132. A plurality of spaces may be implemented in a fixed manner in which a plurality of spaced apart spaces are arranged along the left and right directions D3 and D4 within a range of movement, or may be implemented as a movable space in which a plurality of spaces are moved.

14 is a view for explaining a first control method of the injection unit provided in the coating apparatus according to the present invention.

First, the first control method of the injection unit 320 is applicable to all of the above-described embodiments, but the coating device 100 according to an embodiment of the present invention described with reference to FIGS. 1 to 10 will be described below. Listen and explain.

In addition, the second moving part 130 provided to the coating apparatus 100 according to an embodiment of the present invention described with reference to FIGS. 1 to 10 will be described as a frame 330.

14, the injection unit 320 is mounted to be movable in the left and right directions (D3, D4) on the frame 330, the injection direction can be adjusted by the control unit.

The control unit is a component of the coating apparatus 100 according to the present invention, the injection pressure of the paint sprayed by the injection unit 320, the injection direction, the vertical direction (D1, D2) of the first moving unit 110 It is possible to control the overall coating operation, such as movement along, movement of the frame 330 on the first moving unit 110.

When the sprayer 320 sprays the paint for application of the target surface SF while the sprayer 320 moves in the left and right directions D3 and D4 along the target surface, the protruding portion formed on the target surface SF ( In order to improve the application quality of the side surfaces P1 and P2 of P), the injection direction of the injection unit 320 may be adjusted according to the moving direction of the injection unit 320.

14(a) is a view for explaining a situation in which the spraying direction of the spraying part 320' is applied by a conventional coating device in which the spraying direction is not adjusted, and as shown in the drawing, the side surface of the protruding portion P In P1), the paint is not normally sprayed, so it is difficult to expect quality assurance of coating.

However, in the present invention, as illustrated in FIGS. 14(b) and 14(c), the injection direction of the injection unit 320 is controlled by the control unit, thereby effectively solving the above-described conventional problems.

When the sprayer 320 sprays the paint for application of the target surface SF while the sprayer 320 moves in the right direction D4 along the target surface SF, as shown in FIG. 14(b), The injection unit 320 may be controlled such that the injection direction of the injection unit 320 is biased to the right.

And, as shown in Fig. 14(c), the control unit sprays the paint for application of the target surface SF while the sprayer 320 moves in the left direction D3 along the target surface SF. In this case, the injection unit 320 may be controlled such that the injection direction of the injection unit 320 is biased to the left.

As described above, when the spraying direction of the paint by the spraying part 320 is biased in the right direction or the left direction, the side surfaces P1 and P2 of the protruding part P can be applied precisely to guarantee the quality of the coating. I can do it.

Here, the degree of injection direction of the injection unit 320 by the control unit may vary depending on the size and shape of the projecting portion P, or may be changed based on the injection pressure of the paint by the injection unit 320.

The coating device 100 according to the present invention may include a sensing unit (not shown) for obtaining information on the protruding portion P, and the sensing unit may include a first moving unit 110 for the target surface SF ) In the process of moving from the uppermost line UP1 to the lowermost line LW1 in the vertical direction D1, D2, the surface information of the target surface SF is obtained so that the information of the protruding portion P is obtained. Can be obtained.

The sensing unit is a mechanical contact method for acquiring information by a moving distance for contact with the target surface SF or a time or distance at which light irradiated toward the target surface SF is reflected back from the target surface SF. It may be a component that can be applied, such as an optical method for obtaining information.

The control unit moves based on the surface information of the target surface SF obtained by the sensing unit when moving in the vertical directions D1 and D2 of the first moving unit 110, the moving direction of the spraying unit 320 The degree of the injection direction according to the can be adjusted.

Here, a plurality of the detection units are formed on the first moving unit 110, so that the first moving unit 110 is from the uppermost line UP1 to the lowermost line LW1 of the target surface SF. In the process of being moved, it is possible to obtain surface information for the entire target surface SF.

In other words, in order to apply the first region R1, the second region R2, and the third region R3, the first moving part 110 has a lower direction D2, an upper direction D1, and a lower side. Although sequentially moved along the direction D2, surface information of all target surfaces SF may be obtained by the sensing unit when moving along the lower direction D2 to apply the first region R1. .

Of course, surface information of all target surfaces SF may be obtained by the sensing unit by moving the first moving unit 110 in the vertical direction D1 and D2 irrespective of application.

In addition, the detection unit may be mounted on the frame 330, may be moved in conjunction with the injection unit 320, or prior to the movement of the injection unit 320 on the upstream side of the injection unit 320 It may be moved.

As described above, when the sprayer 320 passes the area where the protruding portion P exists based on the surface information of the target surface SF obtained by the sensing unit, the spraying direction is determined in accordance with the moving direction. In order to bias, the injection unit 320 may be controlled, and when passing through an area where the projecting portion P does not exist, the injection unit may be controlled such that the injection direction is vertical as in the prior art.

Of course, the controller assumes the presence of the protruding portion P on the target surface SF, and when the jetting part 320 moves in the left direction D3 along the target surface, the jetting direction of the jetting part 320 This is to be biased to the left, and when moving in the right direction D4, the jetting direction of the jetting unit 320 may be biased to the right.

15 is a view for explaining a second control method of the injection unit provided in the coating apparatus according to the present invention.

First, it is revealed that the second control method of the spraying unit 420 can be applied to all coating devices spraying the paint while the spraying unit 420 is moved in the left and right directions D3 and D4 as well as the above-described embodiment. .

15, the injection unit 420 is movable in the left and right directions (D3, D4) on the same frame 130 as the second moving unit 130 described with reference to FIGS. 1 to 10, the frame 130 ), and the injection direction may be controlled by the control unit.

The control unit is a component of the coating apparatus according to the present invention, it is possible to control the overall coating operation such as the injection pressure and the spraying direction of the paint sprayed by the injection unit 420.

When the sprayer 420 sprays a coating material for application to the target surface SF while the sprayer 420 moves in the left and right directions D3 and D4 along the target surface SF, the controller The spraying direction of the spraying unit 420 may be adjusted to be applied to the area X exceeding a range that can be moved in the left and right directions D3 and D4.

15(a) is a view for explaining a situation in which a spraying part is coated by a conventional coating device in which the spraying direction is not adjusted, and as shown in the drawing, the spraying part 420' is a frame 430' The distance equal to the width of the left and right directions D3 and D4 cannot be moved.

This is due to the structural characteristics of the left cover frame 434c', the right cover frame 434d', the left and right support frames and the spraying portion 420' constituting the frame 430', and the spraying portion 420' ) Is located at the left end of the left and right support frames as shown in FIG. 15(a), there is a predetermined separation distance Y between the injection part 420' and the left cover frame 434c'. .

Further, even when the injection portion 420' is located at the right end of the left and right support frames, a predetermined separation distance Y exists between the injection portion 420' and the right cover frame 434d'.

The separation distance (Y) as described above eventually results in a specific area (X') of the target surface (SF') despite the injection portion 420 being positioned at the left end of the left and right support frames or the right end of the left and right support frames. There is a problem that the coating is not sprayed, resulting in a problem that the coating quality is lowered.

However, in the present invention, the conventional problems as described above can be effectively solved by controlling the injection direction of the injection unit 420 by the control unit as shown in FIGS. 15(b) and 15(c).

The control unit may be moved on the frame 430 when the sprayer 420 is sprayed with paint while moving in the left direction D3 along the target surface SF as shown in FIG. 15(b). The injection unit 420 may be controlled such that the injection direction is biased to the left at a predetermined first point PO1 from the left end.

The control unit may increase the degree of bias toward the left side while the injection unit 420 passes through the predetermined first point PO1, and the predetermined first point PO1 may be applied to the injection unit 420. It may be determined based on at least one of the injection pressure and the injection range for the paint.

For example, the predetermined first point (PO1) is the larger the injection pressure, and the wider the injection range, the wider the injection range 420 from the left end where the injection unit 420 can be moved. It can be a close point.

In addition, the degree of bias from the predetermined first point PO1 to the left side of the injection portion 420 may be smaller as the injection pressure is larger and the wider the injection range is.

The control unit may be moved on the frame 430 when the sprayer 420 sprays the paint while moving in the right direction D4 along the target surface SF as shown in FIG. 15(c). The injection unit 420 may be controlled such that the injection direction is shifted to the right at a predetermined second point PO2 from the right end.

The control unit may increase the degree of bias toward the right side while the injection unit 420 passes through the predetermined second point PO2, and the predetermined second point PO2 of the injection unit 420 may be increased. It may be determined based on at least one of the injection pressure and the injection range for the paint.

For example, the predetermined second point (PO2) is the larger the injection pressure, and the larger the injection range, the wider, the wider the injection range 420 from the right end where the injection portion 420 can be moved on It can be a close point.

In addition, the degree of bias from the predetermined second point PO2 to the right side of the injection unit 420 may be reduced as the injection pressure is large, and when the injection range is wide, it is small.

As described above, when the spray direction of the paint is changed at the first point PO1 and the second predetermined point PO2 where the spray direction of the paint is changed, the specific area X in which the conventional paint is not sprayed Edo is also sprayed, and it is possible to realize an improvement in coating quality.

16 is a view for explaining a third control method of the injection unit provided in the coating apparatus according to the present invention.

Referring to FIG. 16, the injection unit 520 is movable to the left and right directions D3 and D4 on the same frame 530 as the second moving unit 130 described with reference to FIGS. 1 to 10. ), and the injection direction may be controlled by the control unit.

The control unit is a component of the coating apparatus according to the present invention, it is possible to control the overall coating operation such as the injection pressure and the spraying direction of the paint sprayed by the injection unit 520

When the sprayer 520 sprays the paint for application to the target surface SF while the sprayer 520 moves in the left and right directions D3 and D4 along the target surface SF, the sprayer 520 The spraying direction of the spraying unit 520 may be adjusted so that scattering of the paint due to inertia generated while reaching the left end or the right end that can be moved on the frame is prevented.

16(a) is a view for explaining a situation in which the spraying part is coated by a conventional coating device in which the spraying direction is not adjusted. As shown in the drawing, the spraying part 520' is on the frame 530'. When the left end that can be moved is reached, the paint is scattered to the left outside by the inertia that the injection part 520' moves to the left.

Then, when the sprayer 520' reaches the right end that can be moved on the frame, the paint is scattered to the right by the inertia that the sprayer 520' moves to the right.

The scattering problem as described above causes many problems such as a decrease in coating quality.

However, in the present invention, the injection direction is controlled by the control unit as shown in FIG. 16(b), thereby effectively solving the above-described conventional problems.

When the sprayer 520 is spraying paint while moving in the left direction D3 along the target surface SF, the control unit may be moved on the frame 530 as shown in FIG. 16(b). The injection unit 520 may be controlled such that the injection direction is biased to the right at a predetermined third point PO3 from the left end.

The control unit may increase the degree of bias toward the right side while the injection unit 520 passes through the predetermined third point PO3, and the predetermined third point PO3 may be applied to the injection unit 520. It may be determined based on at least one of the injection pressure and the injection range for the paint.

For example, the predetermined third point (PO3) is the larger the injection pressure, and the wider the injection range, the wider the injection range 520 from the left end where the injection unit 520 can be moved. It can be a close point.

In addition, the degree of bias from the predetermined third point PO3 to the right side of the injection portion 520 may be reduced as the injection pressure is large and the wider the injection range is.

In addition, when the spraying part 520 sprays the paint while moving in the right direction D4 along the target surface SF, a predetermined fourth point from the right end that can be moved on the frame 530 ( In the PO4), the injection unit 520 may be controlled such that the injection direction is biased to the left.

The control unit may increase the degree of bias to the left as the injection unit 520 passes through the predetermined fourth point PO4, and the predetermined fourth point PO4 may be applied to the injection unit 520. It may be determined based on at least one of the injection pressure and the injection range for the paint.

For example, the predetermined fourth point (PO4) is the larger the injection pressure, and the wider the injection range, the wider, the wider the injection portion 520 on the frame 530 can be moved from the right end It can be a close point.

In addition, the degree of bias from the predetermined fourth point PO4 to the left side of the injection portion 520 may be smaller as the injection pressure is larger and the wider the injection range is.

As described above, when the spraying direction of the paint is changed at the predetermined third point (PO3) and the predetermined fourth point (PO4) in the spraying direction of the coating material, the inertia due to the movement of the spraying unit 520 is caused. By preventing scattering of the paint, it is possible to solve various problems that may be caused by the improvement of coating quality and scattering of the paint.

In the above, the configuration and features of the present invention have been described based on the embodiment according to the present invention, but the present invention is not limited to this, and various modifications or changes can be made within the spirit and scope of the present invention. It is apparent to those skilled in the art, and thus, such changes or modifications are found to be within the scope of the appended claims.
