Description

그린타이어의 외경측정장치{Outer Diameter Measure-Meter of Green Tire}Outer Diameter Measure-Meter of Green Tire

본 발명은 성형공정 중인 그린타이어의 외경을 측정하는 장치에 관한 것으로, 특히 그린타이어의 정확한 외경측정이 가능하여 균일한 품질의 제품개선 데이터로 활용할 수 있도록 이루어진 그린 타이어의 외경측정장치에 관한 것이다.The present invention relates to an apparatus for measuring the outer diameter of the green tire during the molding process, and more particularly, to an outer diameter measuring apparatus for green tires, which is capable of accurately measuring the outer diameter of the green tire to be utilized as product improvement data of uniform quality.

일반적으로 그린타이어는 타이어용 고무혼련과, 디핑, 비드제조, 칼렌다 작업 및, 압출작업등을 거친후 이들의 여러 부재를 조립하여 성형 공정에서 제조되는 반제품의 타이어로서, 타이어 제조시 이 그린타이어가 성형공정에서 완성된 다음 가류공정과 마무리 공정을 통해 완성된 타이어를 제조하도록 되어 있다.In general, green tires are semi-finished tires that are manufactured in a molding process by assembling various members after rubber kneading for tires, dipping, bead manufacture, calendar work, and extrusion work. The finished tire is then manufactured through a vulcanization and finishing process.

여기서 그린타이어 성형시 외경관리는 작업공정상 필수 사항으로 성형중인 그린타이어의 외경을 측정하는 장치는 종래 접촉식과 비접촉식 장치가 개발되어 적용하고 있지만, 현장 설비에서 효과적으로 활용되지 못하고 작업자가 주로 줄자를 가지고 수동으로 그린타이어의 외경을 측정하여 그 데이터를 얻도록 되어 있었다.Here, the external diameter management in forming green tires is an essential item in the work process.A device for measuring the outer diameter of green tires during molding is developed and applied to conventional contact and non-contact devices. The outer diameter of the green tire was measured manually to obtain the data.

그러나 이러한 줄자 방식의 측정은 측정자의 오차범위가 클 수밖에 없으며, 측정을 위해 일시적으로 성형작업을 중단하고, 외경오차 수리시 재확인 작업을 수행하는 불합리한 측정작업이 이루어지고 있었다.However, the measurement method of the tape measure has a large error range of the measuring instrument, and the measuring work was temporarily performed to temporarily stop the molding work for the measurement and perform the rechecking operation when repairing the outer diameter error.

한편, 종래 접촉식 측정장치는 그린 타이어 성형시 트레드 압착부의 전진위치를 임의의 거리로 입력함으로서 이 그린타이어의 외경에 관계없이 압착부가 일정거리로 전진하게 되는데, 이때 측정하는 그린 타이어의 외경이 작을 때에는 이 그린 타이어의 트레드에 압착부의 압착롤러가 닿지 않게 되는 반면, 측정하는 그린 타이어의 외경이 클 때에는 트레드에 압착롤러가 과다한 힘으로 접촉하여 변형이 발생하므로 매 작업마다 일정한 힘을 가해주기가 곤란하였다.On the other hand, in the conventional contact measuring apparatus by inputting the advance position of the tread crimping part at a predetermined distance when forming the green tire, the crimping part is advanced at a certain distance regardless of the outer diameter of the green tire, wherein the outer diameter of the green tire to be measured is small. When the green tire's tread does not come in contact with the press roller at the press section, while the outer diameter of the green tire to be measured is large, it is difficult to apply a constant force to each work because the press roller contacts the tread with excessive force. It was.

따라서 그린타이어의 외경측정과 트레드 압착이 별도로 수행되는 번거로움과 측정작업 데이타의 내용이 피드백에 의한 보정작업도 이루어지지 않은 실정이다.Therefore, the inconvenience of measuring the outer diameter and tread compression of the green tire and the contents of the measurement work data have not been corrected by the feedback.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위하여 발명된 것으로, 성형 공정의 중단없이 성형 공정 중 그린 타이어의 외경을 정확하게 측정하여 저장함에 따라 이 그린타이어의 품질개선 데이터로 활용하여 제품의 생산성 증대와 균일한 품질의 타이어를 생산할 수 있는 개선된 그린 타이어의 외경측정장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the conventional problems as described above. As the outer diameter of the green tire is accurately measured and stored without interruption of the molding process, it is utilized as quality improvement data of the green tire to increase product productivity. It is an object of the present invention to provide an improved outer tire diameter measuring apparatus capable of producing tires of uniform quality.

본 발명은 모터(1)에 의해 선형 가이드(2)를 따라 이동하며 엔코더(11)에 의해 전진거리가 측정되는 트레드 압착롤러(3)를 구비한 압착부(4)와, 트레드 센터롤러(5)를 구비하며 선형센서(7)에 의해 전진거리가 측정되는 외경 측정부(6)와, 콘틀롤러(8), 저장부(9) 및 표시부(10)를 구비하며, 콘트롤러(8)는 상기 선형센서(7)에 의해 측정된 데이타를 입력받아 그린타이어의 외경 및 상기 트레드 압착롤러(3)의 전진거리량을 결정하고, 상기 엔코더(11)를 통해 트레드 압착롤러(3)의 전진거리를 감지하여 결정된 트레드 압착롤러의 전진거리와 트레드 압착롤러(3)의 전진거리 일치시키며, 저장부(9)에 외경측정부 및 압착부의 측정된 데이타 저장시키고, 표시부(10)로 측정치를 나타내도록 이루어진 구조이다.The present invention is a compression unit (4) having a tread compaction roller (3) which is moved along the linear guide (2) by the motor (1) and the forward distance is measured by the encoder (11), and the tread center roller (5) And an outer diameter measuring unit 6 having a forward distance measured by the linear sensor 7, a controller 8, a storage unit 9, and a display unit 10. The data measured by the linear sensor (7) is input to determine the outer diameter of the green tire and the advance distance amount of the tread roller (3), and the advance distance of the tread roller (3) through the encoder (11) Sensing and determining the advance distance of the tread compaction roller and the advance distance of the tread compaction roller 3, and store the measured data of the outer diameter measuring section and the crimping section in the storage section 9, and display the measured value with the display section 10 Structure.

도 1 및 도 2 를 참조하여 본 발명의 바람직한 실시예를 보다 자세히 설명한다.1 and 2 will be described in detail a preferred embodiment of the present invention.

상기 트레드 센터롤러(5)를 전진시키면 선형센서(7)에 의해 전진거리를 측정한다. 이때 상기 그린타이어(12)의 회전속도를 콘트롤러(8)로 인가 받아서 이 그린 타이어(12)의 1회전 시간동안만 트레드 센터롤러(5)의 전진거리를 일정시간마다 받아들여서 그린타이어(12)의 외경을 콘틀롤러(8)에서 계산한다.When the tread center roller 5 is advanced, the advance distance is measured by the linear sensor 7. At this time, the rotational speed of the green tire 12 is applied to the controller 8 to receive the advance distance of the tread center roller 5 only for one rotation time of the green tire 12 at a predetermined time, thereby allowing the green tire 12 to be applied. The outer diameter of is calculated by the controller (8).

여기서 상기 트레드 센터롤러(5)의 전진거리(CLI)와 그린타이어(12)의 중심부에서 이 트레드 센터롤러(5)까지의 거리(CL) 및 상기 그린타이어(12)의 중심부터 트레드 센터롤러(5)가 접촉한 거리(CL2)의 관계는 다음의 식 1로 결정된다.Here, the forward distance CLI of the tread center roller 5 and the distance CL from the center of the green tire 12 to the tread center roller 5 and the center of the green tire 12 from the center of the tread center roller 5 The relationship of the distance CL2 which 5) contacted is determined by following formula (1).

(식 1)(Equation 1)

CL2= CL-CL1CL2 = CL-CL1

상기 식 1에 의해 그린타이어(12)의 외경 = 2πCL2로 계산된다.Equation 1 calculates the outer diameter of the green tire 12 = 2πCL2.

이와 반면에 상기 트레드 센터롤러(5)의 전진거리의 값을 트레드 압착롤러(3)의 전진 거리량으로 콘트롤러(8)에서 환산하여 상기 트레드 압착롤러(3) 전진시 엔코더(11)를 사용하여 전진거리를 측정하여 일치하게 되면, 이 트레드 압착롤러(3)의 전진을 정지시킨다.On the other hand, the value of the forward distance of the tread center roller 5 is converted into the forward distance of the tread compaction roller 3 by the controller 8 to use the encoder 11 when the tread compaction roller 3 is advanced. When the forward distance is measured and coincided, the forward of the tread roller 3 is stopped.

즉 트레드 압착롤러 전진거리(PL2)=(CL2)이고, 이 트레드 압착롤러 정지거리(PL1)=PL-PL2이다.That is, the tread compaction roller forward distance PL2 is equal to CL2, and the tread compaction roller stopping distance PL1 is equal to PL-PL2.

이와 같은 본 발명은 콘트롤러(8)의 상기와 같은 계산방식에 의해서 성형중 그린 타이어의 외경을 정확하게 측정하여 저장함에 따라 성형작업을 중단시키지 않고서도 그린 타이어의 외경을 측정 저장하여 제품개선 데이터로 활용할수 있도록 되어 있다.As described above, the present invention accurately measures and stores the outer diameter of the green tire during molding according to the calculation method of the controller 8, thereby measuring and storing the outer diameter of the green tire without interrupting the molding operation, thereby utilizing the product improvement data. I can do it.
