According to an embodiment of the present invention, the object to be painted (P) is transported by a conveyor having a predetermined length, and the object to be painted (P) is painted by spraying paint on the object to be painted (P) during the transport. In the booth system, the conveyor includes: a wiping booth for cleaning the object to be coated (P) introduced into the conveyor; A first painting booth (11) that sprays paint onto the object (P) that has passed through the wiping booth; a first setting booth (21) provided to dry the object (P) that has passed through the first painting booth (11) for a predetermined period of time; a second painting booth (12) for spraying paint on the object (P) that has passed through the first setting booth (21); a second setting booth (22) provided to dry the object (P) that has passed through the second painting booth (12) for a predetermined period of time; a third painting booth (13) for spraying paint on the object (P) that has passed through the second setting booth (22); And a third setting booth (23) provided to dry the object (P) that has passed through the third painting booth (13) for a predetermined time, and is configured to pass through the first painting booth (11) to A paint booth system is provided in which a conveyor is bent at both ends of the third paint booth (13), and a predetermined shielding wall (5) is formed around the bent surface of the conveyor.

The wiping booth refers to a booth (process) that cleans the surface of the object to be painted (P) so that the paint can be well colored on the surface of the object to be painted (P). Depending on the type, etc., it may be omitted.

After the object P passes through the third setting booth 23, a predetermined heat treatment process may be performed, and the heat treatment is preferably performed at a temperature of 80 degrees Celsius for about 40 minutes.

In the above description, 'bending' may mean changing the moving direction of the conveyor at an angle between 60 degrees and 120 degrees. Figure 1 shows an example bent at 90 degrees. The bending point may be configured to have a predetermined curvature, and through this configuration, shaking of the object P at the bending point can be minimized.

Figure 1 shows an example in which the first painting booth 11 is equipped with two nozzles, the second painting booth 12 is equipped with three nozzles, and the third painting booth is equipped with two nozzles. By performing the painting work multiple times (multiple stages) within one painting booth, the painting work can be performed without missing any parts.

In addition, the conveyor includes: a first painting booth conveyor 301 passing through the first painting booth 11; a second conveyor 302 provided in a bent direction at the outlet of the first painting booth 11; a first setting booth conveyor 303 that is bent at an end of the second conveyor 302 and is provided in a direction parallel to the first painting booth conveyor 301; A 2-1 booth connection conveyor 304 that is bent into a predetermined semicircular shape at an end of the first setting booth conveyor 303 and is provided in a direction parallel to the first setting booth conveyor 303; A second painting booth conveyor 305 passing through the second painting booth 12 in a bent direction at an end of the 2-1 booth connecting conveyor 304; A 2-2 booth connection conveyor 306 provided in a bent direction at the outlet of the second painting booth 12; A 2-1 setting booth conveyor 307 that is bent at an end of the 2-2 booth connecting conveyor 306 and is provided in a direction parallel to the second painting booth conveyor 305; A 2-2 setting booth conveyor 308 is bent into a predetermined semicircular shape at an end of the 2-1 setting booth conveyor 307 and is provided in a direction parallel to the 2-1 setting booth conveyor 307. ; A 3-1 booth connection conveyor (309) provided in a bent direction at the end of the 2-2 setting booth conveyor (308); A third paint booth conveyor 310 passing through the third paint booth 13 in a bent direction at an end of the 3-1 booth connection conveyor 309; A 3-2 booth connection conveyor 311 provided in a bent direction at the outlet of the third painting booth 13; A 3-1 setting booth conveyor 312 provided in a direction bent at an end of the 3-2 booth connection conveyor 311 and parallel to the third painting booth conveyor 310; And a 3-2 setting booth conveyor 313 that is bent into a predetermined semicircular shape at an end of the 3-1 setting booth conveyor 312 and is provided in a direction parallel to the 3-1 setting booth conveyor 312. ); can be configured by being connected in series.

Figure 1 shows the shapes of the first painting booth conveyor 301 to the 3-2 setting booth conveyor 313 according to the above embodiment. By configuring the system in such a way that the 2-1 setting booth conveyor 307 moves in the direction opposite to the direction of movement of the second painting booth conveyor 305 of the second painting booth 12, one side of the space where the system is installed is The second setting booth 22 can be formed by using the third setting booth 23 (the same applies to the third setting booth 23). The setting booth can dry the paint applied in the previous process by bringing the object (P) into contact with air for a predetermined period of time.

The form of 'bending into a predetermined semicircular shape' may mean that the conveyor is arranged along a semicircle with a predetermined radius so that the objects P passing through the conveyor on both sides of the bending point do not interfere with each other. For example, at the bending point between the 2-1 setting booth conveyor 307 and the 2-2 setting booth conveyor 308, a bending point having a radius larger than the width of the object to be painted (P) may be formed. there is.

In addition, a plurality of nozzles 4 are disposed in each of the first to third painting booths 11 to 13 to have a spray angle of 120 to 180 degrees, and the first painting booth 11 Primer is sprayed in, color paint is sprayed in the second paint booth (12), and clear paint is sprayed in the third paint booth (13). The moving speed of the conveyor is 3 m/min to 5 m/min, and the length of the conveyor is , the time for the object (P) to pass through the first setting booth 21 is more than 5 minutes, the time it passes through the second setting booth 22 is more than 8 minutes, and the time it passes through the third setting booth 23 is more than 5 minutes. It can be designed to last 7 minutes or more.

Through the above configuration, the setting time (time for the object to be coated (P) to pass through the setting booth) can be designed by adjusting the moving speed of the conveyor and the length of the conveyor in the setting booth. For example, if the length of the conveyor in the setting booth is 20m and the moving speed of the conveyor is 4m/min, a setting time of 5 minutes can be given in the marine setting booth.

If the moving speed of the conveyor is less than 3 m/min, the process progress speed is too slow and production may decrease, and if the moving speed is more than 5 m/min, painting may not be completed completely and defects may occur.

In addition, the conveyor includes: an upper conveyor (31) connected to the upper part of the object (P); A lower conveyor 32 connected to the lower part of the object to be painted (P); An upper hook (33) provided to support the object (P) to be painted on the upper conveyor (31); a rotation motor provided to rotate the upper hook (33); And a lower hook (34) provided to support the object (P) on the lower conveyor (32) and rotated according to the rotation of the object (P), wherein the upper conveyor (31) and The moving speed of the lower conveyor 32 can be controlled to be maintained in the same range.

When the object (P) is transported while connected only to the upper hook (33), the vibration or shaking of the conveyor is applied directly to the object (P), causing vibration (pendulum movement) in the object (P). This may occur, resulting in uneven painting. To prevent this problem, a hook can be connected to the lower part of the object to be painted (P) so that it can be fixed against horizontal vibration/movement.

By configuring the object to be painted (P) to be rotated by a rotation motor as described above, all or some surfaces of the object to be painted (P) can be selectively painted.

In addition, an LED frame (6) is provided on the upper wall of the first painting booth (11) to the third painting booth (13), and the LED frame (6) is formed to be bent at a predetermined acute angle from the wall surface. Including a plurality of mounting portions 61 provided, a plurality of LEDs mounted on the mounting portions 61 radiate light in a downward diagonal direction from the upper part of the wall, so that when the worker M is placed, the worker M ) may be configured to irradiate light in a direction ranging from the top of the object (P) to the bottom of the top of the object (P).

In the conventional paint booth system, the light from the lights installed on the ceiling was blocked by facilities installed on the ceiling of the factory, making it difficult for the worker (M) to check the surface of the object to be painted (P). In the case of installing the light on the wall, the worker (M) had difficulty checking the surface of the object (P). There was a problem with light being obscured by (M)’s body. In an embodiment of the present invention, the LED frame 6 is installed at a position between the ceiling and the wall, and the LED is mounted on the mounting unit 61 in a downward diagonal direction so that the LED has a predetermined angle, thereby preventing lighting loss due to obstacles. You can easily check the surface of the object to be coated (P) without any pressure.
