Description
본 발명은 타이어 제조시 성형드럼으로 공급하는 비드(bead)를 비드로더에서 내경을 측정하여 이상시 불량비드를 선별할 수 있는 타이어의 비드 내경 측정장치에 관한 것이다.The present invention relates to a bead inner diameter measuring apparatus for selecting a bead in the event of an abnormality by measuring the inner diameter of the bead (bead) supplied to the forming drum at the time of manufacture of the tire.
기히 공지된 바와 같이 타이어의 비드란 타이어를 차량의 림에 결합하는 부분으로, 강철로 된 와이어에 일정한 두께로 고무를 입혀서 여러 층으로 감은 다음, 필라(filler) 고무를 부착하고 코드지로 감싼진 구조로 되어 있다.As is well known, the bead of a tire is a part that binds a tire to a rim of a vehicle, and is made of steel wire coated with rubber to a certain thickness, wound into several layers, and then filled with a filler rubber and wrapped with cord paper. It is.
완성된 비드는 성형기로 공급되는 카카스, 사이드월과 함께 부착된 다음, 2차 성형기로 옮겨서 일정한 형상으로 포밍(forming) 한 후 그 위에 벨트와 캡 트레드를 부착하여 그린 타이어를 완성시키도록 되어 있다.The finished beads are attached together with the carcass and sidewall supplied to the molding machine, and then transferred to the secondary molding machine to form into a certain shape, and then a belt and a cap tread are attached to complete the green tire. .
여기서 상기 성형기로 비드를 공급할 때 비드로더를 이용하게 되는바, 그 비드로더(10)는 도 1에 도시된 바와 같이 성형기의 성형드럼(11)으로 비드(5)를 공급하기 위해 먼저 비드세터(12)에 비드를 공급 시키는바, 이때 상기 비드로더(10)는 도 2에 도시된 바와 같이 베이스원판(1)에 장착된 비드롤러(2)가 실린더(9)의 작동으로 회동하는 가동원판(3)의 가이드 홈(4)을 따라 점선의 위치에서 실선의 위치로 이동하여 비드(5)를 팽창시키도록 되어 있다.Here, the bead loader is used when supplying the beads to the molding machine. The bead loader 10 is a bead setter (1) for supplying the beads 5 to the forming drum 11 of the molding machine as shown in FIG. 12, a bead is supplied to the bead loader 10, wherein the bead loader 10 has a movable disc in which the bead roller 2 mounted on the base disc 1 is rotated by the operation of the cylinder 9 ( The bead 5 is inflated by moving from the position of the dotted line along the guide groove 4 of 3) to the position of the solid line.
그러나 이와 같은 비드로더(10)는 팽창된 비드(5)를 도 1의 비드세터(12)에 공급할 때 이 비드(5)의 내경을 제대로 측정하지 못하고 단지 작업자가 경험 등으로 불량 또는 비틀림 비드가 있으면 이를 제거하도록 되어 있으며, 상기와 같은 불량 비드가 작업자의 실수로 제거하지 못하고 성형드럼(11)에 공급되게 되면, 이 성형드럼(11)에 비드(5)가 제대로 안착되지 못하거나 비드(5)를 잡아주지 못하므로 케이스 팽창시 팽창이 불균일하게 발생하게 되어 결국 완성 타이어의 품질을 저하시키는 요인이 되었다.However, when the bead loader 10 supplies the expanded bead 5 to the bead setter 12 of FIG. If it is to be removed, and if such a bad bead can not be removed by the operator accidentally supplied to the forming drum 11, the bead (5) is not properly seated on the forming drum (11) or beads (5) ), The expansion of the case occurs unevenly, resulting in a deterioration of the quality of the finished tire.
이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 비드로더에서 비드의 내경을 측정하여 불량비드를 사전에 선별함으로 별도의 비드 내경 측정시간이 필요하지 않을 뿐만 아니라, 선별된 정상 비드만을 성형드럼에 공급하여 양질의 타이어를 생산할 수 있는 타이의 비드 내경 측정장치를 제공함에 그 목적이 있다. Therefore, the present invention was invented to solve the conventional problems as described above, by measuring the inner diameter of the bead in the bead loader by selecting the bad beads in advance, not only a separate bead inner diameter measurement time is required, but also selected normal beads It is an object of the present invention to provide a bead inner diameter measuring device capable of supplying a bay to a forming drum to produce a high quality tire.
상기와 같은 목적을 달성하기 위한 본 고안은 베이스 원판의 비드롤러들이 가동원판의 가이드 홈을 따라 팽창 및 수축 작용으로 작동하여 비드를 팽창시켜 보유 지지하는 비드로더의 비드 내경 측정장치에 있어서, 상기 가동원판의 축을 기준으로 일정간격으로 이격된 변위센서들이 위치하고 이 변위센서들이 비드의 내경을 측정하는 구조로 되어 있다.The present invention for achieving the above object is in the bead loader bead inner diameter measuring device of the bead rollers of the base disc is operated in the expansion and contraction action along the guide groove of the movable disc to expand and retain the beads, the movable Displacement sensors are spaced at regular intervals from the axis of the disc and these displacement sensors measure the inner diameter of the beads.
이하, 본 발명을 첨부된 예시 도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 2와 도 3은 본 발명에 따른 비드(5)의 내경 측정장치를 나타낸 도면들이다.2 and 3 show the internal diameter measuring apparatus of the bead 5 according to the present invention.
본 발명은 도면에 도시된 바와 같이 베이스 원판(1)의 비드롤러(2)들이 가동원판(3)의 가이드 홈(4)을 따라 팽창 및 수축작용으로 작동하여 비드(5)를 팽창시켜 보유 지지하는 비드로더의 비드 내경 측정장치에 있어서, 상기 가동원판(5)의 축(6)을 기준으로 일정간격(D)으로 이격된 변위센서(7)들이 위치하고, 이 변위센서(7)들이 비드(5)의 내경을 측정하도록 되어 있다.As shown in the drawing, the bead rollers 2 of the base disc 1 operate in the expansion and contraction action along the guide groove 4 of the movable disc 3 to expand and hold the beads 5. In the bead loader internal diameter measuring apparatus of the bead loader, displacement sensors (7) spaced at a predetermined distance (D) with respect to the axis (6) of the movable disk (5) is located, the displacement sensors (7) are bead ( It is to measure the inner diameter of 5).
즉 상기 비드로더(10)에 설치된 변위센서(7)들이 팽창된 비드(5)를 측정하여 도 4에 도시된 PLC 콘트롤러(8)에서 기준값과 비교하여 비드(5)의 불량 유무를 판단하도록 되어 있으며, 허용값을 설정하여 허용치 이내에서만 만들어진 비드만을 성형드럼으로 공급하도록 되어 있다.That is, the displacement sensors 7 installed in the bead loader 10 measure the expanded beads 5 to determine whether the beads 5 are defective by comparing the reference values in the PLC controller 8 illustrated in FIG. 4. The tolerance is set so that only beads made within the tolerance are supplied to the forming drum.
한편, 도 4는 변위센서(7)들이 비드(5)의 내경을 측정할 때 PLC 콘트롤러(8)와 작업 연관관계를 나타내는 작업 흐름도이다.On the other hand, FIG. 4 is a work flow diagram showing the work relation with the PLC controller 8 when the displacement sensors 7 measure the inner diameter of the bead 5.
