On the other hand, the air supply adapter 36 disposed to face the water supply adapter 34 also has the same structure as the water supply adapter 34. That is, the air supply adapter 36 has a coupler 44 to which the other open end portion 26 of the center tube 28 inserted into the rod brush 16 is inserted and coupled to the front surface of the air supply adapter 36. The air supply pipe 46 is connected so that the air supply is made to the coupler 44 side through the inside of the air supply adapter 36 can be advanced by the hydraulic cylinder 48 fixed to the frame 30.

In addition, the pressing plates 50a and 50b are disposed to face each other in a direction parallel to the axis of the rod brush 16 inserted into the frame 30. These pressing plates 50a and 50b have a curved surface 52 almost identical to the curved surface of the rod brush 16 on the opposite surface facing the rod brush 16 and a plurality of drain holes 54 are formed. . These pressing plates 50a and 50b are able to advance and retract with respect to the rod brush 16 by the respective hydraulic cylinders 56 in the frame 30, and are guided in parallel by the guide bars 58 on both sides. do.

On the other hand, the rod brush 16 is allowed to enter the lower space of the opening and closing plate (32a, 32b) and rotatable bristle brushes (60a, 60b) are disposed at both sides of the entered rod brush 16 Upper sprinkling tubes 62a and 62b are disposed on the bristle brushes 60a and 60b, respectively, and lower sprinkling tubes 64 are disposed in the lower middle of the bristle brushes 60a and 60b.

As shown in FIG. 6, the present invention uses a sponge rod cylindrical rod brush 16 mounted on the arm 14 of the robot 18. The rod brush 16 has a plurality of perforations 22 formed therein and a central tube 28 having open ends 24 and 26 inserted into both sides thereof, and both ends of the open ends 24 and 26 are inserted therein. Exposed to the outside and fixed to the arm 14 of the robot 18, the rod brush 16 is not rotated. In this way, the rod brush 16 installed on the robot 18 cleans the surface of the CRT 10 transferred by the inline conveyor 12 installed adjacent to the robot 18. As mentioned above, the CRT 10 is polished by using a dedicated abrasive after the coating process of the surface is completed. After this polishing process, abrasive residues and foreign substances should be removed from the surface.

The rod brush 16 is contaminated in the process of moistening the rod brush 16 and rubbing the surface of the CRT 10. The contaminated rod brush 16 is to be cleaned in the cleaning stage (20). The washing process of the rod brush 16 basically consists of an internal water washing step, an external brush water washing step, a washing water pressure separation step, and an internal air washing step, and these steps may be changed in some order as necessary. In the invention will be described through these basic washing steps.

The contaminated rod brush 16 is moved by the robot 18 into the center of the frame 30 of the cleaning stage 18. When the contaminated rod brush 16 is transferred to the frame 30 of the cleaning stage 18, the water supply adapter 34 and the air supply adapter 36, the opening and closing plates 32a and 32b, and the pressing plate 50a All of 50b are in a retracted state.

First, the rod brush 16 is placed between the water supply adapter 34 and the air supply adapter 36, and these water supply adapter 34 and the air supply adapter 36 are operated by the operation of the respective hydraulic cylinders 42 and 48. It is moved to both ends of the rod brush 16 so that each coupling hole 38 and 44 is coupled to each open end 24 and 26 of the center tube 28 disposed at the center of the rod brush 16. In this way, the water supply adapter 34 and the air supply adapter 36 coupled to the open ends 24 and 26 of the center tube 28 of the rod brush 16 are connected to the air supply pipe 46 of the air supply adapter 36. Water is supplied at high pressure to the water supply adapter 34 through the water supply pipe 40 in a blocked state. Water penetrates into the interior of the rod brush 16 through the perforation 22 of the center tube 28 and pushes out the contaminants penetrated into the contaminated rod brush 16 to the outside, thereby pushing the outside of the rod brush 16. To be discharged. In this manner, internal washing of the rod brush 16 is performed.

Thereafter, the water supply adapter 34 and the air supply adapter 36 are retracted and separated from the rod brush 16. The rod brush 16 having the internal water washing is further lowered into the frame 30 of the washing stage 20 and placed between the bristle brushes 60a and 60b, and the opening and closing plate of the upper bristle brushes 60a and 60b. 32a) and 32b are closed by the operation of each hydraulic cylinder 33 (Fig. 4). In this process, water is sprayed from the upper and lower spray pipes 62a, 62b and 64, and the external brush water washing step is performed while the bristle brushes 60a and 60b rotate. In this washing step, the outer surface of the rod brush 16 is washed with water.

Subsequently, the opening and closing plates 32a and 32b above the bristle brushes 60a and 60b are opened and the rod brush 16 is raised to retreat between the water supply adapter 34 and the air supply adapter 36 which are retracted. , The pressing plates 50a and 50b disposed to face each other in a direction parallel to the axis of the rod brush 16 are moved by the respective hydraulic cylinders 56 to the rod brush 16 side and thus to the rod brush 16. The curved surface 52 of the opposite surface facing toward starts to be pressed as it adheres to the rod brush 16 (FIG. 5). Due to the compression of the pressing plates 50a and 50b, the washing water and some remaining contaminants in the rod brush 16 are drained through the drain holes 54 of the pressing plates 50a and 50b. This completes the wash water compression separation step.

After the washing water compression separation step is completed, the pressing plates 50a and 50b are separated from the rod brushes 16, and the water supply adapter 34 and the air supply adapter 36 are moved to both ends of the rod brushes 16, respectively. Spheres 38, 44 are coupled to each open end 24, 26 of the central tube 28 disposed in the center of the rod brush 16. In this case, air is supplied at high pressure to the air supply adapter 36 through the air supply pipe 46 in a state where the water supply pipe 40 of the water supply adapter 34 is blocked. The high pressure air penetrates into the inside of the rod brush 16 through the through hole 22 of the center tube 28 and pushes the washing water and the remaining contaminants penetrated into the contaminated rod brush 16 to the outside, It is discharged to the outside of the brush 16. In this manner, internal air cleaning of the rod brush 16 is performed.

In this way, the contaminated rod brush 16 in the process of soaking the water in the rod brush 16 and scrubbing the surface of the brown tube 10 has an internal water washing step, an external brush water washing step, a washing water pressure separation step, and internal air. Contaminants can be completely cleaned in the washing process consisting of a washing step.

As such, the present invention supplies high-pressure washing water to the interior of the rod brush for cleaning the surface of the CRT so that the abrasive residue or the abrasive material which is buried inside or near the surface of the brush can be discharged to the outside of the brush. While spraying the wash water on the outer surface of the rod brush, remove foreign substances on the surface with the rotary bristle brush, compress the rod brush containing the wash water to dewater the wash water in the rod brush, and supply high-pressure air back into the rod brush. Thus, the washing water in the rod brush can be discharged and removed to completely clean the contaminants such as the abrasive residue or the abrasive material on the rod brush.
