Description

그린타이어 두께에 따른 가류시간 설정장치와 설정방법{Curing time setting apparatus and setting method according to green tire}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vulcanizing apparatus,

본 발명은 타이어 제조시 성형공정을 끝낸 그린타이어를 가류할 때 그린타이어의 가류시간을 설정하는 방법과 장치에 관한 것으로, 특히 그린타이어 가류시 필요한 가류시간을 그린타이어 트레드의 두께에 따라 적정하게 설정하여 가류하는 그린타이어 두께에 따른 가류시간 설정장치와 설정방법에 관한 것이다.The present invention relates to a method and apparatus for setting a vulcanization time of a green tire when vulcanizing a green tire which has been subjected to a molding process in the production of a tire, and more particularly to a method and apparatus for setting a vulcanization time required for vulcanization of a green tire, The present invention relates to a vulcanizing time setting device and a setting method according to the thickness of a green tire vulcanized.

일반적으로 타이어의 제조는 타이어 제조에 필요한 각종 원료를 혼합해 타이어에 사용되는 고무를 배합해 내는 정련공정(믹싱공정 이라고도 함)을 거치고, 상기 정련공정에서 생산된 배합고무를 압출과 압연공정을 통해 반제품화 한 후, 성형공정에서 타이어에 사용되는 모든 구성 반제품들을 성형기에서 순차적으로 붙여서 원통형의 그린타이어를 만든 다음, 상기 성형공정을 마친 그린타이어를 가류몰드에 넣어 일련의 열과 압력을 가하여 배합된 고무를 화학적으로 결합시키어 타이어의 안정된 고유성질을 얻는 가류공정을 거치게 되면, 완제품 타이어가 제조된다.In general, the manufacture of a tire involves a refining process (also referred to as a mixing process) in which various raw materials necessary for manufacturing a tire are mixed to form a rubber used in a tire, and the rubber compound produced in the refining process is subjected to extrusion and rolling After semi-finished products, all semi-finished products used for the tire in the molding process are sequentially stuck to each other in a molding machine to form a cylindrical green tire, and then the molded green tire is put into a vulcanization mold to apply a series of heat and pressure, Is chemically bonded to obtain a stable intrinsic property of the tire, an end product tire is produced.

이와 같은 타이어의 제조공정 중 가류공정에서는 가류되는 그린타이어 규격에 따라 일정한 가류시간 동안 열과 압력을 받아 가류가 진행되는데, 그러나 가류시간은 압출과 압연공정 등을 통해 생성된 반제품들 간 두께 편차와 그린타이어의 트레드 두께 편차 등이 고려되지 않고 일률적으로 가류시간을 설정하여 가류가 진행되었다.In the vulcanization process of the tire manufacturing process, the vulcanization proceeds under a certain vulcanization time according to the vulcanized green tire standard. However, the vulcanization time depends on the thickness deviation between the semi-finished products produced through the extrusion and rolling processes, The vulcanization progressed by setting the vulcanization time uniformly without considering the variation of the thickness of the tread of the tire and the like.

종래 이러한 가류시간 설정은 규격별로 설정된 그린타이어의 두께에 따라 일정하게 설정되어 왔으나, 이 같은 종래 가류방식은 가류하는 타이어에 최적화된 가류시간을 설정하는 것이 곤란하여 적정 가류시간 보다 통상적으로 길게 가류시간을 설정할 수밖에 없기 때문에 가류가 완료된 후 완제품 타이어의 품도 저하가 발생되는 단점이 있었다.Such a vulcanization time is conventionally set according to the thickness of the green tire set according to the standard. However, in the conventional vulcanization system, it is difficult to set the vulcanization time optimized for the vulcanizing tire, so that the vulcanization time So that the article of the finished product tires is lowered after vulcanization is completed.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 그린타이어를 가류기에 투입하기 전 그린타이어의 트레드 부위별 두께를 측정하고 측정된 두께 변화에 따른 가류시간을 유동적으로 조절하여 가류시킴에 따라 타이어의 가류품도 향상으로 완제품 타이어의 품도 개선이 이루어지는 그린타이어 두께에 따른 가류시간 설정장치와 설정방법을 제공함에 그 목적이 있다.SUMMARY OF THE INVENTION Accordingly, the present invention has been made in order to solve the above problems, and it is an object of the present invention to measure the thickness of a tread portion of a green tire before a green tire is introduced into a vulcanizer, The present invention provides a vulcanizing time setting device and a setting method according to the thickness of a green tire in which the vulcanized product of a tire is improved to improve the quality of an article of finished tire.

즉, 본 발명은 도 1에 도시된 바와 같이 그린타이어(1)를 가류기에 투입하는 로더(2)에서 이 로더(2)의 수평대(3)를 따라 이동 가능하게 설치되는 두께 측정기(4)와, 이 두께 측정기(4)의 신호를 감지하는 센서 감지기(5) 및, 상기 센서 감지기(5)의 두께 측정신호에 따라 가류시간이 계산되는 PLC(6)로 이루어져서 상기 PLC의 지령에 따른 가류기의 가류시간이 재조정되는 구조로 되어 있다.That is, according to the present invention, as shown in Fig. 1, a thickness measuring device 4, which is movably installed along a horizontal base 3 of a loader 2, for loading a green tire 1 into a vulcanizer, A sensor sensor 5 for sensing a signal of the thickness measuring instrument 4 and a PLC 6 for calculating a vulcanizing time according to a thickness measurement signal of the sensor sensor 5, So that the curing time of the vessel is readjusted.

여기서 상기 로더(2)는 공지와 같이 가류기의 지지 프레임(7)에 설치된 수직 가이드바(8)를 따라 승하강용 실린더(9)에 의해 업다운 이동됨과 동시에, 상기 지지 프레임(7)의 수평 가이드바(10)를 따라 수평방향으로 좌우 이동하여 성형공정을 마친 그린타이어(1)를 집어 공지의 가류기에 투입할 수 있도록 되어 있다.The loader 2 is moved up and down by a vertical lifting cylinder 9 along a vertical guide bar 8 provided on a support frame 7 of a vulcanizer as well known in the art, The green tire 1 that has been subjected to the molding process can be picked up and introduced into a known vulcanizer by horizontally moving the bar 10 along the horizontal direction.

이 같은 상기 로더(2)에는 이의 수평대(3)를 따라 좌우로 이동하는 이격되어 설치된 한 쌍의 두께 측정센서(4a,4b)를 갖춘 두께 측정기(4)가 설치되어 있어서 다양한 타이어 규격에 맞추어 로더(2)로 집어 올린 그린타이어(1)의 트레드(1a) 부위를 각 부위단위로 두께 측정할 수가 있다.The loader 2 is provided with a thickness measuring device 4 having a pair of thickness measurement sensors 4a and 4b spaced apart from each other and moving left and right along the horizontal band 3 thereof. The thickness of the portion of the tread 1a of the green tire 1 picked up by the loader 2 can be measured in units of parts.

이렇게 상기 두께 측정기(4)에서 측정된 그린타이어(1)의 트레드 부위 두께 신호는 PLC(6)에 설치된 센서 감지기(5)로 인가되고, 상기 센서 감지기(5)에서 PLC(6)로 신호를 보내면, 상기 PLC(6)는 센서 감지기(5)를 통해 측정값을 인식하여 자동으로 가류시간을 계산하도록 되어 있다.The tread portion thickness signal of the green tire 1 measured in the thickness measuring device 4 is applied to the sensor sensor 5 installed in the PLC 6 and the signal from the sensor sensor 5 to the PLC 6 The PLC 6 recognizes the measured value through the sensor sensor 5 and calculates the crawl time automatically.

따라서 상기 PLC(6)에서 재설정된 가류시간을 가류기로 전달되어 타이어의 트레드 두께 변화에 따라 맞추어 설정되어 그린타이어(1)의 가류시간을 정확하게 조절하도록 되어 있기에 종래와 같이 과가류에 대한 문제점을 해결한다.Therefore, the vulcanizing time reset in the PLC 6 is transferred to the vulcanizer, and is adjusted according to the change in the thickness of the tire, so that the vulcanization time of the green tire 1 is precisely controlled. Resolve.

한편, 본 발명에 따른 그린타이어 두께에 따른 가류시간 설정방법은 다음과 같다.The method of setting the vulcanizing time according to the thickness of the green tire according to the present invention is as follows.

로더(2)에 물려진 그린타이어(1)의 트레드부(1a) 두께를 두께 측정기(4)로 측정하는 단계와, 상기 두께 측정기(4)로 측정된 신호가 센서 감지기(5)로 인가되어 PLC(6)로 전달되는 단계, 상기 PLC(6)에서 타이어 규격별 두께 변화에 따른 가류시간 재설정하는 단계 및, 상기 PLC(6)에서 재설정된 가류시간에 따라 가류기의 가류가 진행되는 단계로 이루어져 있다.Measuring the thickness of the tread portion 1a of the green tire 1 held by the loader 2 with the thickness measuring instrument 4 and measuring the thickness of the tread portion 1a of the green tire 1 by applying a signal measured by the thickness measuring instrument 4 to the sensor sensor 5 The method according to claim 1, further comprising the steps of: (a) returning the vulcanizing time to the PLC (6), (c) consist of.

그리고 그린타이어(1)의 가류시간 재설정은 가류되는 그린타이어(1)의 두께에 맞추어 공지의 제어장치인 PLC(6)에서 자동계산 되어지는데, 동일 규격이어도 그린타이어(1)의 두께편차에 따라 가류시간 설정기준을 적용하여 가류 스펙 대비 변경하여 가류시간이 계산된다.The vulcanization time resetting of the green tire 1 is automatically calculated in the PLC 6 which is a known control device in accordance with the thickness of the vulcanized green tire 1. In accordance with the thickness variation of the green tire 1 The vulcanization time is calculated by changing the vulcanization specification by applying the vulcanization time setting standard.

예를 들어, 승용차용 그린타이어(모델명 PCR 205/65R17 H415)의 두께편차(두께 실측시 스펙대비 1㎜ 작용 경우)에 따라 가류스펙시간인 10분 30초를 적용하게 되는데, 이에 따라 최종 가류시간은 가류스펙시간-그린타이어 두께편차(로직)로 설정됨에 따라 9분 30초 동안 가류된다.For example, according to the thickness deviation of the green tire for a passenger car (model name PCR 205 / 65R17 H415) (when 1 mm of the spec is used in the thickness measurement), the vulcanization spec time of 10 minutes 30 seconds is applied, Is vulcanized for 9 minutes and 30 seconds as it is set to the vulcanization spec time - green tire thickness deviation (logic).

상기와 같은 본 발명은 그린타이어 가류시 가류되는 그린타이어의 규격에 맞추어 가류시간을 유동적으로 조절함에 따라 과가류가 방지되어 과가류로 인한 가류품도 저하와 생산성 저감을 감소시킬 수 있도록 되어 있다.According to the present invention as described above, the vulcanization time can be flexibly adjusted in accordance with the standard of the green tire vulcanized during the vulcanization of the green tire, so that the overflow can be prevented so that the vulcanization due to overflow can be reduced and the productivity reduction can be reduced have.
