본 발명은 타이어 제조중 압연공정에 설치되는 EPI(Each Per Inch)롤러에 관한 것으로, 더욱 상세하게는 여러 규격의 EPI롤러를 단일 EPI롤러로 통합하여 각 규격의 압연 스틸코드에 맞는 EPI롤러를 조절하여 사용할 수 있는 압연공정의 EPI 롤러 장치에 관한 것이다.The present invention relates to an EPI (Each Per Inch) roller that is installed in the rolling process during tire manufacturing, and more specifically, to integrate EPI rollers of various specifications into a single EPI roller to adjust the EPI rollers for each rolled steel cord of the standard. It relates to an EPI roller device of a rolling process that can be used by.

타이어의 압연공정은 스틸코드에 일정두께의 고무를 입히는 작업으로 일명 톱핑(Topping)작업이라고도 한다.The rolling process of tires is a process of coating rubber with a certain thickness on a steel cord, also known as topping operation.

이와 같은 압연공정에서 EPI롤러들은 스틸코드에 고무를 입히는 토핑과정에서 스틸코드의 간격을 일정하게 유지시켜 줌으로써 최종적으로는 타이어 제조 후, 성능 균일성(Uniformity)에 중요한 역할을 한다.In the rolling process, EPI rollers maintain a constant gap between steel cords in the topping process of rubber coating on steel cords, and thus play an important role in uniformity after tire manufacturing.

이러한 압연공정의 EPI롤러들을 이용하는 압연 스틸코드의 직경들은 통상 1.64㎜ ~ 0.61㎜ 범위를 가지도록 되어 있다.The diameters of the rolled steel cords using EPI rollers in this rolling process are usually in the range of 1.64 mm to 0.61 mm.

그러나 종래 각 규격에 맞는 압연 스틸코드의 다양한 직경을 위해 여러 대의 EPI롤러를 사용하게 되었는바, 즉 도 2와 같은 압연설비의 칼렌다 롤러(1)들을 통하여 배출되는 스틸코드(2)들은 규격에 맞는 EPI롤러(10)를 통하여 토핑된 스틸코드(2)로 배출되어 다음 공정으로 이송되었다.However, conventionally, several EPI rollers are used for various diameters of rolled steel cords meeting each standard, that is, the steel cords 2 discharged through the calender rollers 1 of the rolling equipment as shown in FIG. It was discharged to the steel cord 2 topping through the EPI roller 10 and transferred to the next process.

그러나 종래 EPI롤러들은 각각의 스틸코드 규격에 맞는 EPI롤러들을 사용하여야 하기 때문에 여러 대의 EPI롤러들을 준비해야 하고, 이를 교체할 때마다 번번히 수작업에 의해 장탈착 작업을 수행하므로서 오장탈착의 문제와 교체 작업시간이 과다하게 소요될 뿐만 아니라, 사용하지 않는 EPI롤러들은 별도의 보관장소에 보관하는 공간사용에도 불합리한 문제점이 있었다.However, conventional EPI rollers have to use EPI rollers that meet the steel code specifications. Therefore, several EPI rollers need to be prepared. In addition to excessive time, unused EPI rollers had unreasonable problems in using space stored in a separate storage location.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 단일 EPI롤러를 이용하여 스틸코드의 다양한 규격에 맞추어 조절하여 사용할 수 있 기 때문에 스틸코드의 규격 변경시 별도의 교체작업 없이 다양한 스틸코드 생산에 정확하게 맞추어 사용할 수 있으면서 작업환경에 대한 효율적 공간사용도 가능하게 이루어지는 압연공정의 EPI롤러 장치를 제공함에 그 목적이 있다.Therefore, the present invention was invented to solve the conventional problems as described above, and can be used to adjust to various specifications of the steel cord using a single EPI roller, so that a variety of steel without a separate replacement when changing the specifications of the steel cord It is an object of the present invention to provide an EPI roller device for a rolling process that can be used precisely for the production of a cord and also enables efficient use of a space for a work environment.

상기와 같은 목적을 달성하기 위한 본 발명은 EPI간격 폭들을 조절하는 나사 회전축과, 이 나사 회전축을 구동시키는 구동모터, 이 구동모터와 나사 회전축을 연결시키는 구동 전달축 및, 상기 구동모터를 제어하는 제어부로 이루어져 있어서 스틸코드의 규격 변경시 이 스틸코드의 직경 규격에 맞는 EPI간격 폭을 조절하여 사용할 수가 있도록 되어 있다.The present invention for achieving the above object is a screw rotation axis for adjusting the EPI interval widths, a drive motor for driving the screw rotation axis, a drive transmission shaft for connecting the drive motor and the screw rotation shaft, and controlling the drive motor It is composed of a control unit, and when changing the standard of steel cord, it is possible to adjust the width of the EPI gap that meets the diameter standard of this steel cord.

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 압연공정에 설치되는 EPI롤러 장치를 나타낸 개략 구성 단면도이고, 도 2는 본 발명이 압연공정에 적용된 사용 상태도이다.1 is a schematic sectional view showing an EPI roller device installed in a rolling process according to the present invention, Figure 2 is a state diagram used in the present invention applied to the rolling process.

본 발명은 압연설비의 칼렌다 롤러(1)들을 통하여 배출되는 고무가 토핑 압연된 스틸코드(2)들을 간격(3)들 사이로 통과시키어 배출하는 압연공정의 EPI롤러 장치에 있어서, 상기 간격(3)들을 형성하는 롤러편(4)들은 제어부(5)에 의해 제어되는 구동모터(6)의 동력 전달축(7)을 매개로 연결된 나사 회전축(8)에 동일 직선상으로 배치되어 있으며, 이 나사 회전축(8)에 교대로 형성된 정방향 회전축인 정 나사부(8a)와 역방향 회전축인 역 나사부(8b)에는 롤러편(4)들이 각각 나선 결합되어 이 나사 회전축(8)의 회전에 따라 EPI 간격(3) 폭이 좌우로 조절되는 구조로 되어 있다.The present invention relates to an EPI roller apparatus of a rolling process in which rubber discharged through calendar rollers (1) of rolling equipment passes through steel cords (2) topping-rolled through the gaps (3), wherein the gaps (3) The roller pieces 4 forming the blades are arranged in the same straight line on the screw rotation shaft 8 connected via the power transmission shaft 7 of the drive motor 6 controlled by the control unit 5, and this screw rotation shaft The roller pieces 4 are spirally coupled to the forward threaded portion 8a, which is the forward rotational shaft alternately formed at (8), and the reverse threaded portion 8b, which is the reverse rotational shaft, so that the EPI interval (3) is in accordance with the rotation of the screw rotational shaft 8. The width is adjusted to the left and right.

그리고 상기 나사 회전축(8)을 구동시키는 구동모터(6)는 제어부(5)에 의하여 이 나사 회전축(8)을 정/역 방향으로 회전시킬 수 있도록 되어 있으면서 회전 RPM은 약 1700 ~ 1500으로 설정되어 있다.The drive motor 6 for driving the screw rotation shaft 8 is configured to rotate the screw rotation shaft 8 in the forward / reverse direction by the control unit 5 while the rotation RPM is set to about 1700 to 1500. have.

또한 상기 나사 회전축(8)에 의하여 EPI간격(3)은 12, 15, 17, 19(EPI)의 EPI 간격조절이 가능하도록 되어 있는바, 즉 상기 모터(6)의 동력 전달축(7)에는 나사 회전축(8)이 연결되어 있으며, 이 나사 회전축(8)에는 정방향 회전축인 정나사부(8a)와 역방향 회전축인 역나사부(8b)가 교대로 배치되고, 이들 정나사부(8a)와 역나사부(8b)에는 동일한 롤러편(4)들이 각각 나선 결합되어 있다.
따라서 상기 나사 회전축(8)이 정/역 회전하면 이들 롤러편(4)들은 정나사부(8a)와 역나사부(8b)에 의해 동시에 동일한 간격으로 벌어지거나 좁혀지도록 되어 있습니다. 예를 들어 19 EPI 일때는 이 롤러편(4)들의 EPI 간격(3)이 가장좁고 12 EPI 일때의 EPI 간격(3)이 가장 넓어지도록 EPI 간격조절이 가능하도록 되어 있다.In addition, the screw rotation shaft 8 allows the EPI interval 3 to adjust the EPI interval of 12, 15, 17, 19 (EPI), that is, the power transmission shaft 7 of the motor 6 The screw rotation shaft 8 is connected, and the screw rotation shaft 8 is alternately arranged with a forward screw portion 8a, which is a forward rotation shaft, and a reverse screw portion 8b, which is a reverse rotation shaft, and these forward screw portions 8a and a reverse thread portion ( The same roller piece 4 is spirally coupled to 8b), respectively.
Therefore, when the screw rotation shaft (8) rotates forward / reverse, these roller pieces (4) are opened or narrowed at the same time by the forward screw portion (8a) and the reverse screw portion (8b) at the same time. For example, when it is 19 EPI, the EPI interval 3 can be adjusted so that the EPI interval 3 of these roller pieces 4 is the narrowest, and the EPI interval 3 when 12 EPI is widest.

한편, 도 3은 본 발명의 작동 흐름도를 도시한 것으로, 필요에 따라 EPI롤(10)의 간격(3)을 조절하고자 할 경우 상기 제어부(5)는 EPI 변경신호를 받아 데이터를 리딩하게 되고 이 리딩한 데이터를 분석하여 구동모터(6)에 신호를 인가시키게 된다.On the other hand, Figure 3 shows the operation of the present invention, if necessary to adjust the interval (3) of the EPI roll 10, the control unit 5 receives the EPI change signal to read the data A signal is applied to the driving motor 6 by analyzing the read data.

그러면 이 구동모터(6)는 제어부(5)의 설정치에 맞추어 나사 회전축(8)을 구동시키어 EPI롤(10)에서 EPI간격(3)을 조절하게 된다.Then, the drive motor 6 drives the screw rotation shaft 8 in accordance with the set value of the control unit 5 to adjust the EPI interval 3 in the EPI roll 10.

이렇게 EPI간격(3)이 조절된 EPI롤(10)은 압연설비의 카렌다 롤러(1)들에서 배출되는 토핑된 스틸코드(2)들을 규격에 맞는 EPI간격(3)으로 통과시키도록 되어 있다.The EPI roll 10 in which the EPI interval 3 is adjusted is configured to pass the topping steel cords 2 discharged from the calendar rollers 1 of the rolling equipment to the EPI interval 3 conforming to the standard.

상기와 같이 본 발명에 따른 압연공정의 EPI롤러 장치는 EPI간격 폭이 스틸코드의 규격에 맞추어 조절되기 때문에 압연 준비시간을 줄이고, 나사 회전축을 통해 신속한 EPI를 구현한 수 있으며, 더욱이 종래 EPI롤 교체시 수동작업으로 인한 오장착에 대한 불량을 방지하면서 EPI롤의 자동화를 이룰 수 있도록 되어 있다. As described above, the EPI roller device of the rolling process according to the present invention can reduce the rolling preparation time because the width of the EPI is adjusted to the specifications of the steel cord, it is possible to implement a rapid EPI through the screw rotation shaft, and moreover replace the conventional EPI roll It is possible to achieve automation of EPI rolls while preventing defects caused by manual operation.
