Description
본 발명은 그린 타이어의 균일성을 측정하는 측정장치에 관한 것으로, 더욱 상세하게는 그린 타이어 성형공정 중에서 그린 타이어의 균일성을 체크할 수 있도록 함으로서 성형공정에서 발생되는 성형 품질의 문제점을 조기에 대처하여 다음 공정인 가류 및 검사 공정에서 나타나는 품질 불량률을 감소시킬 수 있게 하는 그린 타이어의 균일성 측정장치에 관한 것이다.The present invention relates to a measuring device for measuring the uniformity of the green tire, and more particularly, it is possible to check the uniformity of the green tire during the green tire molding process to cope with the problems of molding quality occurring in the molding process at an early stage. The present invention relates to a uniformity measuring apparatus for green tires, which can reduce a quality defect rate occurring in a next step of vulcanization and inspection.
일반적으로 타이어를 성형시킴에 있어서는 먼저 타이어를 구성하는 각각의 반제품(인너라이너, 카카스, 벨트 사이드월, 트래드 등)을 성형시키고, 이들 반제품을 성형드럼상에서 적층 압착시켜 그린 타이어를 성형시키게 되며, 성형이 완료된 그린 타이어는 가류금형내에 장입되고 고온 고압에 의해 가류되어 완성된 타이어가 생산되는 것이다.In general, in molding a tire, each semi-finished product (inner liner, carcass, belt sidewall, tread, etc.) constituting the tire is first formed, and these semi-finished products are laminated and pressed on a forming drum to form a green tire. The molded green tire is charged into a vulcanization mold and vulcanized by high temperature and high pressure to produce a finished tire.
타이어는 원형의 구룸바퀴로서 타이어의 균일성(유니포머티)은 타이어의 품질 면에서 아주 중요한 인자이다.The tire is a round wheel, and the uniformity of the tire (uniformity) is a very important factor in the quality of the tire.
지금까지 타이어의 균일성을 측정하기 위해서는 가류공정을 거친 완성 타이어를 정밀한 림에 장착시키고, 타이어의 내부로 공기압을 충전시킨 다음 로드휠에 부하를 걸어 타이어의 칫수와 힘의 크기 및 변화를 측정하여 왔다.(특허번호 US5228337, WO9109746 참조)Until now, in order to measure the uniformity of the tire, the finished tire after the vulcanization process has been mounted on a precise rim, the air pressure is filled into the tire, and the load is applied to the road wheel to measure the size and change of the tire. (See Patent Nos. US5228337, WO9109746)
그러나 상기 측정장치는 가류공정을 거친 완성된 타이어에 한해서만 측정이 가능한 것으로서 가류공정의 전 단계인 그린 타이어 성형 공정에서의 균일성 측정장치는 전무한 실정이다.However, the measuring device is capable of measuring only the finished tire that has undergone the vulcanization process, and there is no uniformity measuring device in the green tire forming process, which is a preliminary step of the vulcanization process.
본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로서, 본 발명은 그린 타이어의 성형공정에서 그린 타이어의 균일성을 측정할 수 있게 함으로서 성형 공정에서 발생되는 성형 품질의 문제점을 조기에 대처하여 다음 공정인 가류 및 검사 공정에서 나타나는 품질 불량률을 감소시킬 수 있게 하는 그린 타이어의 균일성 측정장치를 제공함에 그 목적이 있다.The present invention has been made to solve the above-described problems, the present invention is to measure the uniformity of the green tire in the molding process of the green tire to cope with the problems of the molding quality occurring in the molding process early to the next step It is an object of the present invention to provide an apparatus for measuring the uniformity of green tires that can reduce the quality defect rate that appears in the phosphorus vulcanization and inspection process.

That is, the present invention comprises a forming drum in which each semi-finished product is laminated, a stitching roll for pressing each semi-finished product to the forming drum, and a cylinder device for bringing the stitching roll into close contact with the forming drum.

첨부된 도면 도 1 은 본 발명에 따른 그린 타이어 균일성 측정장치를 도시한 개략도 이다.1 is a schematic diagram showing an apparatus for measuring green tire uniformity according to the present invention.
도 1 에 도시되는 바와 같이, 본 발명은 각각의 반제품이 적층되는 성형드럼(7)과, 상기 성형드럼(7)에 각각의 반제품을 압착시키는 스테칭롤(2)과, 상기 스테칭롤(2)을 성형드럼(7)에 밀착시키는 실린더장치로(3) 구성되는 것에 있어서, 상기 실리더장치(3)에 스테칭롤(2)에 전가되는 부하를 감지하고 이를 전기적인 신호로 변환시키는 압력 변환기(4)를 설치시키고, 상기 압력 변환기(4)의 신호를 인가 받아 압력 변환기(4)에 감지된 부하 량을 연산하고, 연산 값에 따라 성형기(8)를 제어하는 콘트롤러(5)와, 상기 콘트롤러(5)에 연결되어 콘트롤러(5)의 측정값을 표시하는 디스플레이 장치(6)로 구성되는 것이다.As shown in FIG. 1, the present invention provides a forming drum 7 on which each semi-finished product is stacked, a stitching roll 2 for pressing each semi-finished product onto the forming drum 7, and the stitching roll 2. In the cylinder device (3) in close contact with the forming drum (7), the pressure transducer for detecting the load transferred to the stitching roll (2) to the cylinder device (3) and converts it into an electrical signal ( A controller 5 for installing 4), calculating the amount of load sensed by the pressure transducer 4 by receiving the signal of the pressure transducer 4, and controlling the molding machine 8 according to the calculated value; And a display device 6 which is connected to 5 to display the measured value of the controller 5.
이와 같이 구성되는 본 발명은 성형드럼(7)에 인너라이너와 카카스, 벨트, 비드 및 사이드월을 순차적으로 적층시키고, 최종적으로 트래드부를 설치시키기 전에 스테칭롤(2)을 성형드럼(7)에 적층된 각각의 반제품을 압착시킨다.According to the present invention, the inner liner, the carcass, the belt, the bead and the sidewall are sequentially stacked on the forming drum 7, and the stitching roll 2 is attached to the forming drum 7 before finally installing the tread portion. Each stacked semifinished product is pressed.
스테칭롤(2)을 성형드럼(7)에 압착시키기 위하여 실린더장치(3)를 동작시켜 피스톤의 선단부에 결합된 스테칭롤(2)을 상승시켜 성형드럼(7)에 적층된 각각의 반제품에 압착되게 한다.In order to squeeze the stitching roll 2 to the forming drum 7, the cylinder device 3 is operated to raise the stitching roll 2 coupled to the front end of the piston to press the respective semi-finished products laminated to the forming drum 7. To be.
이때 각각의 반제품을 압착시키는 과정에서 스테칭롤(2)을 통하여 적층설치된 그린 타이어의 표면 상태가 피스톤을 거쳐 압력 변환기(4)에 전달되고, 압력 변환기(4)는 스테칭롤(2)로부터 전달되는 압력을 전기 신호로 변화시켜 콘트롤러(5)에 인가시키게 된다.At this time, in the process of pressing each semi-finished product, the surface state of the green tires laminated through the stitching roll 2 is transmitted to the pressure transducer 4 via the piston, and the pressure transducer 4 is transferred from the stitching roll 2. The pressure is converted into an electrical signal and applied to the controller 5.
압력 변환기(4)로부터 전기적인 신호를 인가 받은 콘트롤러(5)는 내장된 프로그램에 의해 그린 타이어 표면 압력 즉, 평균 압력, 낮은 압력(lowest pressure), 높은 압력(higest pressure) 값을 측정하게 되며, 측정된 압력값과 위치(angle)가 디스플레이 장치(6)로 인가되어 표시됨으로써 작업자가 그린 타이어의 불 균일한 부분을 정확하게 파악할 수 있게 된다.The controller 5, which receives an electric signal from the pressure transducer 4, measures the tire pressures, i.e., average pressure, lower pressure, and higest pressure, which are drawn by the built-in program. The measured pressure value and angle are applied to the display device 6 to be displayed so that the operator can accurately grasp the uneven portion of the green tire.
그리고 측정된 값중 가장 큰 값을 나타내는 부위(angle)가 성형드럼(7)의 상단에 위치되도록 성형기(8)를 제어함으로서 작업자가 불 균일한 부분을 육안으로 용이하게 식별할 수 있게 한다.And by controlling the molding machine 8 so that the angle (angle) representing the largest value of the measured value is located on the top of the forming drum (7), the operator can easily identify the non-uniform parts with the naked eye.
본 발명은 전술한 실시 예에 한정되지 않고 본 발명의 기술사상이 허용하는 범위 내에서 다양하게 변형하여 실시할 수가 있다.The present invention is not limited to the above embodiments, and various modifications can be made within the scope allowed by the technical idea of the present invention.
이상에서와 같이 본 발명에 따르면 그린 타이어의 성형공정중에 그린 타이어의 균일 상태를 용이하게 식별할 수 있어 성형 품질의 문제점을 조기에 해결함으로서 다음 공정인 가류 및 검사 공정에서 나타나는 품질 불량을 감소시킬 수 있을 뿐만 아니라 측정장치의 효용성이 증대되어 타이어의 품질 향상을 한 단계 높일 수 있는 효과가 있다.As described above, according to the present invention, it is possible to easily identify the uniform state of the green tire during the molding process of the green tire, thereby solving the problem of molding quality early, thereby reducing the quality defects appearing in the next process, vulcanization and inspection process. In addition, the utility of the measuring device is increased, thereby improving the tire quality.
