And the other side is an opening and closing piston 7 hinged to the rear of the upper surface of the body 3, the opening and closing piston 7 and one side is hinged and the other side is a connecting rod attached to the center of the fixing rod (8a) (7a), the fixing bracket (8b) is attached to the body while rotatably wrapping both sides of the fixing rod (8a), the opening and closing plate (8) which is a rectangular plate attached to the fixing rod (8a), the body (3) A connecting bracket 9 attached to the center portion of the lower surface, an outgoing piston 10 attached to one side of the connecting bracket 9, and a rotating motor attached through the outgoing piston 10 and the bracket 10a; 11a), the rotary shaft 11b extending from the top of the rotary motor 11a and having a coupling 11d for eccentricity correction, A bearing 11c installed for smooth rotation of the rotary shaft 11b, a stopper 11 connected to the rotary shaft 11b, and one side of the lower surface of the body 3 are hinged and the other side is supported by the support frame 1. Tilting piston (2) is fixed to the upper surface, dust suction duct 13 is installed below the body 3, the dust suction duct 13 is composed of a dust collector (14) connected to the body (3) A plurality of inlet detector 20 and a freely rotating rotary roller 16 are installed in the interior of the tire 15 to detect the inlet of the tire 15, while the stopper 11 has a body via a lower portion of the body 3. (3) It is installed to enter and exit inside.

Meanwhile, the air spray 5 is connected to a supply line 17 through which compressed air flows, and a check valve 18 and a filling tank 19 are connected to the supply line 17.

In addition, the rollers 12 of the inlet conveyor to which the tire 15 is transported are installed to be inclined downward by a predetermined angle relative to the horizontal line so that the tire 15 to be transported is naturally moved in the working direction by its own weight.

Accordingly, when the tire 15 subjected to the buffing operation is introduced into the body 3 via the roller 12 of the inlet conveyor, the inlet of the tire 15 is detected by the inlet detector 20. At the same time, as the rod of the opening and closing piston 7 is extended to push the connecting rod 7a, the opening and closing plate 8 is rotated downward to close the rear part of the body 3.

Subsequently, the rod of the advance piston 10 is contracted and the stopper 11 is raised, and the stopper 10 is inserted into the inner bead portion (rim mounting space) of the tire 15 so as to flow the tire 15. Will be blocked.

Then, when the rod of the tilting piston (2) is contracted and the body (3) is inclined forward by about 30 degrees to contact the inlet of the dust suction duct (13), the rod of the driving piston (4) is expanded to the Air spray (5) and the pneumatic rod (6) is lowered, at which time the end of the pneumatic rod (6) which is lowered in the air is in contact with the tire (15) is pushed up as the pneumatic rod (6) Detected by the magnet sensor (6a), and then the expansion of the drive piston (4) rod is stopped, the air spray (5) maintains an ideal distance from the tire.

Subsequently, compressed air flowing from the supply line 17 is injected into the tire 15 through the air spray nozzle 5, and at the same time, the rotary motor 11a is operated to rotate the stopper 11. By the rotation of 11, the tire 15 is rotated while sliding on the rotary roller 16 of the body 3. In this case, since the tire 15 is inclined by about 30 °, the tire 15 is rotated while being in close contact with the stopper 11, while the instability of rotation due to the gap between the rotation shaft 11b and the stopper 11 is caused by the bearing 11c. The coupling 11d compensates for the eccentricity caused by the inclination of the rotating shaft 11b.

Accordingly, the tire 15 is rotated by the stopper 11 while spraying the compressed air at the fixed position of the air spray 5, so that the entire tire 15 is within the operating range of the air spray 5. Dust is removed, and the removed dust is discharged to the outside via the dust suction duct 13 by the suction force of the dust collector 14.

When the compressed air spraying operation through the air spray 5 ends after a predetermined time has elapsed, the body 3 is raised in the reverse order of the above-described operation, and the stopper 11 is lowered so that the inlet conveyor is inclined. The tire 15 moves along the roller 12 in the post-work progress direction.

Therefore, the tire after the buffing operation is moved to the next process after the dust is removed and discharged in the buffing dust removal apparatus according to the present invention, at this time dust scattering phenomenon due to the compressed air injected from the air spray (5) to the surrounding facilities It can be prevented to prevent contamination of the surrounding facilities, it is possible to shorten the operation time by optimizing the compressed air injection interval of the tire 15 and the air spray (5).

As described above, according to the present invention, the air spray on the upper part of the body is operated while stopping and rotating the tire introduced into the body configured to be inclined forward by about 30 ° through the stopper to remove dust from the tire, The removed dust is discharged to the outside through the connected dust suction duct, so that the removed dust is discharged directly to the dust suction duct within the body of the buffing dust removal device despite the strong compressed air of the air spray. As well as preventing contamination of the surrounding facilities, it is possible to shorten the air spray operation time required in the conventional buffing operation and to maintain the optimum spraying distance to shorten the process time.
