For example, the case may be moved in the horizontal direction on the frame 110 .

Meanwhile, the case may be omitted.

Here, as an example, the applicator 200 is disposed on the arrangement space formed by the case, and may further include a shape output unit 210 forming the inner space S1 .

As an example, the shape output unit 210 is disposed on the arrangement space to limit the range in which the paint sprayed by the nozzle unit 220, which will be described below, is applied to the target surface W, so that a preset number, shape It may be configured to be applied to the target surface (W).

For example, the shape output unit 210 may be disposed on the case, and may be directly or indirectly connected to the frame 110 by the case.

For example, the shape output unit 210 may be provided on a surface opposite to the nozzle unit 220 so as to limit the range in which the paint sprayed by the nozzle unit 220, which will be described below, is applied to the target surface W. An opening S2 having a shape of may be formed.

That is, the paint sprayed by the nozzle unit 220 may be applied to the target surface W through the opening S2 , and the paint that does not pass through the opening S2 is the shape output unit 210 . It can be sprayed on the inner surface of the

Meanwhile, the applicator 200 may further include a nozzle unit 220 disposed on the inner space S1 of the shape output unit 210 and spraying paint to the target surface W.

For example, the nozzle unit 220 may be configured to spray paint by pneumatic and/or hydraulic pressure.

For example, the nozzle unit 220 may be connected to a supply pipe for supplying paint to spray paint supplied from the supply pipe.

In addition, the nozzle unit 220 may include a storage tank for storing the paint, so that the supply pipe may be omitted.

Here, as an example, the nozzle unit 220 and the shape output unit 210 may be moved in a horizontal direction with respect to the target surface W, and further, the shape output unit 210 may have a predetermined center It is rotated based on the axis X to change the position of the opening S2 with respect to the nozzle unit 220 .

To explain this in more detail, as an example, the nozzle unit 220 and the shape output unit 210 are directly connected to the frame 110 by a known moving member such as a rail or a gear (not shown). It may be moved in the horizontal direction with respect to the target plane W, or may be indirectly moved in the horizontal direction based on the target plane W by the case.

Also, the shape output unit 210 may be rotated with respect to the central axis X by a rotating member such as a rotating shaft, a rotating gear, and a rotating arm (not shown) connected to the shape output unit 210 .

The central axis X may be in a direction parallel to the vertical direction.

As a result, as the shape output unit 210 is rotated based on the central axis X, the position of the opening S2 opposite to the nozzle unit 220 disposed in the inner space S1 is The range of the paint sprayed to the target surface W through the opening S2 may be adjusted.

Here, as an example, the shape output unit 210 may have a cylindrical shape, and the opening S2 may have a triangular shape when the cylindrical shape output unit 210 is expanded.

To explain this in more detail, the shape output unit 210 may be a cylindrical pipe tube shape having a hollow to form the inner space S1 as a whole, and the opening S2 is the shape output unit having a cylindrical shape. When 210 is cut and expanded in the vertical direction, it may have a triangular shape.

In this case, the opening S2 may be formed in a direction in which one side of the triangular shape is parallel to the vertical direction.

As a result, when the opening S2 is located at a position adjacent to one side parallel to the vertical direction with respect to the nozzle unit 220, the paint is applied to the target surface W relatively long in the vertical direction. When the opening S2 is located at a position far from one side parallel to the vertical direction with respect to the nozzle unit 220, the paint is applied to the target surface W relatively short in the vertical direction. can be

Meanwhile, the application unit 200 may further include an application limiting unit 230 disposed between the shape output unit 210 and the nozzle unit 220 .

For example, the application limiting part 230 is disposed in the inner space S1 and has a cylindrical shape having a hollow as a whole, and on one surface in the vertical direction so that the paint sprayed by the nozzle part 220 is discharged to the outside. An open hole may be formed.

As shown in FIG.

For example, the application limiting unit 230 may be rotated based on the central axis (X) in the same principle as the shape output unit 210 .

On the other hand, the application limiting unit 230 is not essential, and a user may selectively install or omit the application limiting unit 230 .

Here, for example, the nozzle unit 220 and the shape output unit 210 may be moved in the vertical direction with respect to the target surface (W).

To explain this in more detail, the nozzle unit 220 and the shape output unit 210 may be moved in the vertical direction with respect to the target surface W due to the winding of the wire WI.

In addition, the nozzle unit 220 and the shape output unit 210 may be moved in the vertical direction by a known vertical moving member such as a rail or a gear (not shown) with respect to the frame 110 . .

Here, for example, the shape output unit 210 may be moved in the vertical direction with respect to the nozzle unit 220 .

That is, the shape output unit 210 may not only be positionally moved in the vertical direction with respect to the target surface W, but also be positioned and moved in the vertical direction relative to the nozzle unit 220 . may be

Hereinafter, it will be described that the number 1 is applied to the target surface W by the shape output unit 210 with reference to FIG. 4 .

For example, as shown in FIG. 4 , in order to apply the part a2 of the number 1, the shape output unit 210 is rotated so that the opening S2 is a1 having a length corresponding to a2 in the vertical direction. It may be rotatably disposed to face the nozzle unit 220 .

As a result, when the nozzle unit 220 sprays the paint, the paint sprayed from the nozzle unit 220 may be injected to the target surface W through the opening S2 corresponding to a1 .

On the other hand, while the shape output unit 210 and the nozzle unit 220 are moved to the right in the horizontal direction, the shape output unit 210 is rotated at the same time as the opening ( The location of S2) may be changed.

As shown in FIG. 4 , in order to apply the part a4 of number 1, the shape rule force part is rotated so that the opening S2 has a length corresponding to a4 in the vertical direction a3 to the nozzle part 220. They may be rotated to face each other.

Furthermore, at the same time, the shape output unit 210 may be moved (d) in the vertical direction with respect to the nozzle unit 220 so that the paint is sprayed on the portion a4 .

As a result, the shape output robot 100 can apply the desired number or shape to the target surface W by implementing the rotation of the shape output unit 210 and movement of the position in the horizontal and vertical directions. have.

On the other hand, as shown in FIG. 2 , the applicator 200 further includes a cleaner 240 for wiping the paint existing on the inner surface of the shape output unit 210 by being moved in the internal space S1 . can do.

As an example, the cleaner 240 is a component for wiping paint, and when the application limiting part 230 is present, it comes into contact with the inner surface of the application limiting part 230 to wipe off the paint adhered to the inner surface, If the application limiting part 230 is omitted, it may come into contact with the inner surface of the shape output unit 210 while being moved in the inner space to wipe off the paint adhered to the inner surface.

Hereinafter, the cleaner 240 will be described in more detail by limiting the case in which the application limiting part 230 is omitted for convenience of description.

For example, the cleaner 240 may have a cylindrical shape forming a hollow as a whole, and the nozzle unit 220 may be disposed in the hollow of the cleaner 240 .

Here, for example, the cleaner 240 may be moved to a first position that is a position out of the inner space S1 and a second position that is moved to the inner space S1 .

To explain this in more detail, the cleaner 240 is repeated to the first position and the second position with respect to the shape output unit 210 by a known vertical moving member such as a rail or a gear (not shown). position can be moved.

For example, the first position may be a position disposed above the shape output unit 210 in the vertical direction away from the shape output unit 210 , and the second position may be located on the inner space S1 . It may be a position in contact with the inner surface of the shape output unit 210 by entering the .

At this time, when moving from the first position to the second position, the outer surface of the cleaner 240 comes into contact with the inner surface of the shape output unit 210 to remove the paint deposited on the inner surface of the shape output unit 210 . can be wiped off

Also, the inner surface of the cleaner 240 may simultaneously wipe off the paint adhered to the tip of the nozzle unit 220 while the nozzle unit 220 comes into contact with the tip, which is the end of the paint spraying end.

For example, the cleaner 240 may be made of a material such as fiber or synthetic resin.

Here, as an example, the cleaner 240 may be rotated based on the central axis (X).

To explain this in more detail, the cleaner 240 includes the shape output unit ( 210) can be relatively rotated.

As a result, the cleaner 240 can more easily wipe off the paint adhered to the inner surface of the shape output unit 210 .

Meanwhile, as shown in FIG. 2 , the application unit 200 faces the cleaner 240 and further includes a storage unit 250 for storing the paint separated from the inner surface of the shape output unit 210 . can do.

For example, the storage unit 250 may be disposed at a position opposite to the cleaner 240 in the vertical direction, and may be disposed below the shape output unit 210 in the vertical direction.

For example, the storage unit 250 may be configured to receive and store the paint flowing downward on the inner surface of the shape output unit 210 .

For example, the storage unit 250 may be configured to surround a lower outer surface of the shape output unit 210 , and may be screw-coupled to the shape output unit 210 .

Accordingly, when a large amount of paint is stored in the storage unit 250 , the operator may separate the storage unit 250 from the shape output unit 210 and discard the paint stored in the storage unit 250 .

As described above, in the shape output robot 100 according to an embodiment of the present invention, the nozzle unit 220 limits the range in which the paint sprayed by the nozzle unit 220 is applied to the target surface W. Various numbers and shapes may be applied to the target surface W while adjusting the position of the opening S2 on the surface opposite to .
