Description

타이어 균일성 검사용 림{Rim for tire uniformity inspection}Rim for tire uniformity inspection

본 발명은 완성 타이어의 검사공정 중 균일성(Uniformity) 검사시 균일성 검사 측정값의 신뢰도를 향상시키면서 별도의 윤활장치 불사용으로 주변 오염도를 개선할 수 있는 타이어 균일성 검사용 림(Rim)에 관한 것이다.The present invention is a tire uniformity test rim (Rim) that can improve the degree of ambient contamination by the use of a separate lubricator while improving the reliability of the uniformity test measured value during the uniformity test during the inspection process of the finished tire. It is about.

타이어 제조시 가류공정을 마치고 사상(Trimming)과 수리공정을 끝낸 완성 타이어는 창고로 입고시키기 전에 최종적으로 검사공정을 거치게 된다.When the tire is manufactured, the finished tire after finishing the vulcanization process and finishing the trimming and repairing process is finally inspected before being put into the warehouse.

완성 타이어의 검사공정은 검사원의 외관검사를 거쳐 타이어의 균일성을 확인하는 균일성 검사를 거치게 되는바, 여기서 상기 타이어의 균일성 검사에서는 완성 타이어를 검사용 림에 조립하게 되는데, 이때 타이어가 림에 안착이 잘되도록 윤활액을 림 플랜지와 결합하는 타이어의 비드부에 도포해 준다.The inspection process of the finished tire is subjected to a uniformity test to check the uniformity of the tire through the appearance inspection of the inspector, wherein in the tire uniformity test, the finished tire is assembled to the inspection rim, where the tire is a rim Apply lubricant to the bead portion of the tire that engages the rim flanges for proper seating.

타이어의 비드부의 윤활유 도포는 타이어가 림에 부착될 때 밀착이 잘되어서 타이어 균일성 검사시 측정 신뢰도를 향상시킬 뿐만 아니라, 균일성 측정 완료 후 상기 림에서 타이어를 분리시킬 때 해제가 잘되도록 도와주게 된다.Lubrication of the bead of the tire ensures good adhesion when the tire is attached to the rim, which not only improves measurement reliability when checking tire uniformity, but also helps to release the tire when detaching the tire from the rim after the uniformity measurement is completed. do.

한편, 상기 윤활제를 도포하는 윤활장치는 도포부위 및 도포량 변화에 따라 반복 측정되는 균일성 검사 측정값의 변화를 유발시키며, 이러한 변화를 최소화하 기 위하여 도포부위 확대 등을 수행하고 있지만 근본적으로 해결되지 않음에 따라 완성 타이어의 균일성 검사시 최초 측정값과 여러 번 측정값이 다르게 나오고 있는 실정이었다.On the other hand, the lubrication device for applying the lubricant causes a change in the uniformity test measured value repeatedly measured in accordance with the application site and the coating amount changes, and in order to minimize such a change, the application site expansion, etc. is not fundamentally solved. As a result, when the uniformity of the finished tire was checked, the measured value was different from the initial measured value several times.

이러한 윤활유 도포방식은 도 3을 참조로 부언하면, 타이어(101)의 비드부(101a) 면과 검사용 림(102)의 상하 플랜지(103) 면에 우레탄 스폰지 등을 이용하여 밀착한 후 타이어를 회전시키면서 이 스폰지를 통해 공급되는 윤활액(106)을 이들 미부착 부위에 도포하여서 도 3과 같이 검사용 림(102)에 장착하여 균일성 검사 위해 데이터를 측정하게 되었다.3 is a method of applying lubricating oil, after contacting the surface of the bead portion 101a of the tire 101 with the upper and lower flange 103 surfaces of the inspection rim 102 by using a urethane sponge or the like, the tire is applied. The lubricating liquid 106 supplied through the sponge while being rotated was applied to these unattached portions and mounted on the inspection rim 102 as shown in FIG. 3 to measure data for uniformity inspection.

그러나 종래에는 상기 도포되는 윤활액(106)의 도포량과 도포부위가 다양한 규격을 갖는 타이어마다 다르므로, 이로 말미암아 림(102)과 밀착 정도가 타이어(101) 마다 미세하게 다르게 나타나며, 이는 균일성 검사 측정값에 영향을 미치게 되어 결국 측정 데이터의 신뢰도를 떨어뜨리는 결과를 초래하였다.However, in the related art, since the coating amount and the application site of the applied lubricating liquid 106 are different for each tire having various specifications, the degree of close contact with the rim 102 is slightly different from tire to tire 101, which is uniformity test measurement. This affects the value, which in turn lowers the reliability of the measurement data.

또한, 종래 도포액 윤활장치를 이용하는 경우 윤활액이 검사설비 주변을 오염시켜 작업환경이 열악해지는 문제점도 지니고 있었다.In addition, when using a conventional coating liquid lubricating device had a problem that the working environment is poor because the lubricating liquid contaminated around the inspection equipment.

이에 본 발명은 상기와 같은 종래 문제점을 감안하여 발명된 것으로, 완성 타이어의 균일성 검사시 타이어를 림에 부착할 때 윤활액 도포를 사용하지 않으면서 균일성 검사의 측정값 오류를 최소화 시킴에 따라 측정 신뢰도 향상과 주변 오염을 제거한 타이어 균일성 검사용 림을 제공함에 그 목적이 있다.Accordingly, the present invention has been invented in view of the above-described conventional problems, and the measurement is performed by minimizing the measurement error of the uniformity test without using a lubricating fluid when the tire is attached to the rim during the uniformity test of the finished tire. The aim is to provide a rim for tire uniformity inspection with improved reliability and removal of surrounding contamination.

상기와 같은 목적을 달성하기 위한 본 발명은 완성 타이어의 균일성 검사를 위해 타이어 비드부가 림의 플랜지에 밀착 장착되는 타이어 균일성 검사용 림에 있어서, 상기 림의 플랜지에는 이 플랜지 접촉 둘레면을 따라 다수의 볼들이 일정간격으로 배치되되, 상기 볼들은 체임버 홈에 내장되어 타이어 비드부와 구름마찰로 접촉하여 일정한 마찰력을 유지시켜 주도록 되어 있다.The present invention for achieving the above object is a tire uniformity inspection rim in which the tire bead is closely mounted to the flange of the rim for uniformity inspection of the finished tire, the flange of the rim along the flange contact circumferential surface A plurality of balls are arranged at regular intervals, the balls are built into the chamber groove to maintain a constant friction by contacting the tire bead portion and the rolling friction.

상기와 같은 본 발명에 따른 타이어 균일성 검사용 림은 완성 타이어의 균일성 검사시 윤활제 도포를 불필요하게 되어 주변 오염을 개선하고 반복 측정 데이터 값의 신뢰도 향상이 이루어지는 효과를 지닌다.The tire uniformity test rim according to the present invention as described above has the effect of eliminating the need for applying a lubricant during the uniformity test of the finished tire to improve the surrounding contamination and to improve the reliability of repeated measurement data values.

이하, 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 타이어 균일성 검사용 림의 부분 사진이고, 도 2 (A)와 (B)는 본 발명의 림에서 타이어 비드부의 부착 및 탈착 관계를 보여주는 도면들 이다.1 is a partial photograph of the tire uniformity test rim according to the present invention, Figure 2 (A) and (B) is a view showing the relationship between the attachment and detachment of the tire bead portion in the rim of the present invention.

본 발명은 완성 타이어(1)의 균일성 검사를 위해 이 타이어(1)의 비드부(1a)가 림(2)의 플랜지(3)에 밀착 장착되는 타이어 균일성 검사용 림에 있어서, 상기 림(2)의 플랜지(3)에는 이 플랜지(3)의 접촉 둘레면을 따라 다수의 볼(4)들이 등간격으로 배치되되, 상기 볼(4)들은 체임버 홈(5)에 내장되어 플랜지(3) 접촉면에서 약간 돌출 장착되어 있다.The present invention relates to a tire uniformity inspection rim in which the bead portion 1a of the tire 1 is closely attached to the flange 3 of the rim 2 for uniformity inspection of the finished tire 1, wherein the rim In the flange (3) of the (2) a plurality of balls (4) are arranged at equal intervals along the contact circumferential surface of the flange (3), the balls (4) are embedded in the chamber groove (5) and the flange (3) ) It is mounted slightly protruding from the contact surface.

즉, 본 발명에 따른 림(2)의 플랜지(3)에는 볼(4)들이 내장 장착됨에 따라 타이어(1)의 비드부(1a)가 상기 림(2)에 접촉하여 도 2 (A)와 같이 화살표 방향으로 장착될 때 림(2)의 플랜지(3) 접촉면보다 볼(4)들이 돌출됨에 따라, 상기 비드부(1a)는 체임버 홈(5) 내에서 회전하는 볼(4)들과 구름마찰 작용으로 마찰력이 최소화되면서 장착될 뿐만 아니라, 이 볼(4)들에 의해 일정한 마찰력을 유지할 수 있다.That is, as the balls 4 are mounted in the flange 3 of the rim 2 according to the present invention, the bead part 1a of the tire 1 comes into contact with the rim 2 and with FIG. 2 (A). As the balls 4 protrude from the contact surface of the flange 3 of the rim 2 when mounted in the direction of the arrow as shown, the bead portion 1a is rolled with balls 4 rotating in the chamber groove 5. Not only the friction force is minimized and mounted, but also the friction force can be maintained by the balls 4.

이로 인하여 종래와 같이 본 발명은 별도의 윤활유 도포장치 없이 타이어(1)를 균일성 검사용 림(2)에 간편하게 장착시킬 수 있으며, 타이어의 반복 측정에서도 처음 측정값과 거의 변화없는 측정값을 얻기 때문에 균일성 측정 데이터의 신뢰성을 얻을 수 있다.Due to this, the present invention can easily mount the tire 1 to the uniformity inspection rim 2 without a separate lubricating oil applying device as in the prior art, and obtains the measured value almost unchanged from the initial measured value even in repeated measurement of the tire. Therefore, the reliability of the uniformity measurement data can be obtained.

한편, 타이어 균일성 검사 완료 후에는 도 2 (B)와 같이 타이어(1)의 비드부(1a)를 화살표 방향으로 힘을 가하게 되면, 플랜지(3)의 볼(4)들은 도 2 (A)와 반대 방향으로 회전하여 구름마찰 방식으로 비드부(1a)를 림(2)에서 이탈시키게 된다.On the other hand, after the tire uniformity test is completed, when the bead portion 1a of the tire 1 is applied in the direction of the arrow as shown in FIG. 2 (B), the balls 4 of the flange 3 are moved to FIG. It rotates in the opposite direction to and the bead portion (1a) is separated from the rim (2) in a rolling friction manner.
