타이어 제조를 위한 압출물 중량 부적합품 표시장치{Indication apparatus of tire extrudate weight faulty product}Indication apparatus of tire extrudate weight faulty product

본 발명은 타이어 제조공정 중 압출공정에서 압출물 중량 부적합품 표시장치에 관한 것으로, 더욱 상세하게는 타이어 제조를 위한 압출공정에 있어 생산되는 압출물의 중량 부적합 발생 시 이를 압출물에 표시하여 성형공정에서 부적합 반제품 사용을 막음으로써 생산되는 타이어의 품질을 균일화할 수 있는 타이어 제조를 위한 압출물 중량 부적합 표시장치에 관한 것이다.The present invention relates to an apparatus for displaying an unsuitable weight of an extrudate in an extrusion process during a tire manufacturing process, and more particularly, when an unsuitable weight of an extrudate produced in an extrusion process for manufacturing a tire is displayed on an extrudate, it is not suitable for a molding process. The present invention relates to an extrudate weight nonconformity display device for manufacturing a tire capable of uniformizing the quality of a tire produced by preventing the use of semi-finished products.

기 공지된 바와 같이 타이어를 제조하는 과정에서 정련공정을 마친 시트고무는 압출공정의 압출기를 통해 압출물 반제품으로 만들어지고, 이 압출물 반제품들이 성형공정의 성형드럼에서 부착 어셈블리(Assembly)되어 그린타이어가 성형 되어진다.As known in the art, the sheet rubber, which has been refined in the manufacture of tires, is made into an extruded semi-finished product through an extruder of an extrusion process, and the extruded semi-finished products are attached to an assembly drum of a molding process, and the green tire is Is molded.

여기서 상기 압출공정에 생산되는 압출물은 배합고무의 물성이나 압출 작업조건에 의해 프로파일이 변동될 수 있다.Here, the extrudate produced in the extrusion process may vary in profile due to the physical properties of the rubber compound or the working conditions of the extrusion.

이러한 압출작업에서 압출물의 프로파일은 대부분 작업자의 경험과 감각에 의해 맞춰지기 때문에 변동이 빈번하게 발생하고 있으나, 성형공정 이전 단계에서 이를 가려낼 수 있는 장치가 없는 상황이다. 특히 압출물 중량이 관리 허용치를 벗어나게 될 경우 타이어 제조시 불량이 발생할 수 있을 뿐만 아니라 내구성능을 떨어뜨려 소비자의 안전에 위험을 줄 수 있다.In this extrusion operation, the profile of the extrudate is often changed because it is tailored by the experience and the senses of the operator, but there is no device capable of screening it before the forming process. In particular, if the extrudate weight is out of the control allowance, not only the defects in tire manufacturing may occur, but also the durability may be impaired, which may endanger consumer safety.

종래 이와 같은 압출공정을 좀더 자세히 설명하면, 도 1에 도시된 바와 같이 정련공정을 마친 시트고무(1)는 압출기(2)의 압출 스크류(3)들을 통하여 개별 압출전 배합고무(1)들이 헤드 금형부(11)로 동시에 투입되어 이 압출기(2)의 헤드 금형부(11)에서 서로 조합되어 압출된 다음, 일련의 컨베이어(4)들과 냉각장치를 거쳐 화살표 방향을 따라 다음 공정인 성형공정으로 이동하기 위해 권취장치(12)에 적재 되어진다.Conventionally, such an extrusion process will be described in more detail. As shown in FIG. 1, the sheet rubber 1 that has been refined as shown in FIG. 1 has the head of each compound pre-extrusion compounding head 1 through the extrusion screw 3 of the extruder 2. Simultaneously injected into the mold part 11 and extruded in combination with each other in the head mold part 11 of the extruder 2, and then through a series of conveyors 4 and a cooling device to the next step along the direction of the arrow It is loaded in the winding device 12 to move to.

그러나 종래 압출기(2)에서 헤드 금형부(11)를 통과한 압출물(6)들은 배합고무의 물성, 압출 작업조건에 의해 프로파일과 중량이 변동되는데 압출물이 관리 허용치에서 벗어날 경우, 부적합 구간을 쉽게 구분할 수 없어 부적합 반제품으로 타이어를 제조하는 문제점이 있었다.However, in the conventional extruder 2, the extrudate 6 passed through the head mold part 11 is varied in profile and weight depending on the physical properties of the rubber compound and the working conditions of the extrusion. There is a problem in manufacturing a tire as a non-compliant semi-finished product can not be easily distinguished.

따라서, 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 압출 공정작업에 있어서 압출물의 중량을 측정하여 중량이 관리 허용치에서 벗어날 경우 이를 압출물 표면에 자동으로 표시함으로써 부적함품을 쉽게 구분하고 균일한 반제품을 사용하여 완제품 타이어의 품질을 향상시키는 타이어 제조를 위한 압출물 중량 부적합품 표시장치를 제공함에 그 목적이 있다.Therefore, the present invention has been invented to solve the conventional problems as described above, by measuring the weight of the extrudate in the extrusion process operation, if the weight deviates from the control allowance by automatically displaying it on the surface of the extrudate to easily distinguish An object of the present invention is to provide an extrudate weight non-conforming device display device for manufacturing tires, which improves the quality of finished tires by using uniform and semi-finished products.

상기 목적을 달성하기 위하여, 본 발명은 정련된 시트고무들이 호퍼와 스크류, 배럴을 갖춘 압출 스크류에 공급되어 이 압출기의 헤드 금형부를 통해 반제품 압출물로 토출 압출되는 압출기에 있어서, 상기 압출설비는 압출물의 중량을 측정할 수 있는 중량계와, 부적합 발생시 이를 표시하기 위한 마킹장치 및, 마킹장치를 컨트롤 할 수 있는 컨트롤러가 설치되어 있다.In order to achieve the above object, the present invention is an extruder in which the refined sheet rubber is supplied to an extrusion screw having a hopper, a screw, a barrel and ejected and extruded into a semi-finished extrudate through the head mold of the extruder, wherein the extrusion equipment is extruded A weighing scale capable of measuring the weight of water, a marking device for displaying a non-conformity, and a controller for controlling the marking device are installed.

상기와 같이 본 발명은 타이어 제조에 필요한 반제품 제조시 생산되는 압출물의 중량을 정확하게 측정하여 중량 부적합 발생시, 이를 압출물에 표기하여 균일한 압출물 반제품을 사용하게 함으로써 타이어의 불량을 감소시키고, 타이어의 내구성을 확보함으로써 소비자의 안전을 도모할 수 있는 효과를 지닌다.As described above, the present invention accurately measures the weight of the extrudate produced during the manufacture of semi-finished products required for tire manufacture, and when the weight mismatch occurs, it is marked on the extrudate to use a uniform extrudate semi-finished product to reduce the defect of the tire, By securing durability, it has the effect of promoting consumer safety.

2 is a partially enlarged configuration diagram showing the main part of the present invention.

이하, 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명을 설명하기에 앞서 종래구조와 동일한 부분에는 동일한 참조부호를 사용한다.Prior to describing the present invention, the same reference numerals are used for the same parts as the conventional structures.

도 1은 본 발명이 적용된 종래 통상적인 압출기의 전체 구성도이고, 도 2는 본 발명의 요부를 나타낸 부분 구성도이다.1 is an overall configuration diagram of a conventional conventional extruder to which the present invention is applied, Figure 2 is a partial configuration diagram showing the main part of the present invention.

본 발명은 정련된 배합고무(1)들이 압출기(2)의 스크류(3)에 공급되어 이 압출기의 헤드 금형부(11)를 통해 반제품 압출물(6)로 토출 압출되는 압출기(2)와 이 압출물(6)이 무게를 측정하는 중량계(5)를 구비하여 이루어진 타이어 제조를 위한 압출물 중량 부적함품 표시장치에 있어서, 상기 중량계(5)에서 기준관리 허용치를 벗어날 경우 이를 압출물(6)에 표시할 수 있는 마킹장치(9)와 이 마킹장치(9)의 제어를 위한 컨트롤러(10)가 설치된 구조로 되어 있다.The present invention relates to an extruder (2) in which refined compound rubber (1) is supplied to the screw (3) of the extruder (2) and discharged and extruded into the semi-finished extrudate (6) through the head mold part (11) of the extruder. In the extrudate weight non-defective display device for tire production made by the extrudate (6) is provided with a weighing scale (5) to measure the weight, when the extrudate (standard) is out of the standard control allowance, it is the extrudate ( The marking device 9 which can be displayed on 6) and the controller 10 for controlling the marking device 9 are provided.

그리고 상기 컨트롤러(10)는 작업자에 의해 제어되는 공지의 PC(8)의 PLC(7)와 연결되어 제어된다.The controller 10 is connected to and controlled by the PLC 7 of the known PC 8 controlled by the operator.

여기서 상기 중량계(5)는 압출물 1m당 측정 범위가 0.4 내지 0.5㎏ 보다 크고, 측정단위는 0.1㎏ 이하인 것이면 된다, 즉, 이 중량계(5)는 압출물(6)의 단위길이당 중량을 미세하게 측정할 수 있는 크기이면 상관없다.Wherein the weight scale 5 is a measurement range per 1m of the extrudate is larger than 0.4 to 0.5kg, the measuring unit may be 0.1kg or less, that is, the weight scale 5 is the weight per unit length of the extrudate 6 It does not matter if it is the size which can measure microscopically.

이어 본 발명의 작용을 살펴보면, 압출기(2) 헤드 금형부(11)를 통과한 압출물(6)이 컨베이어(4)를 따라 이송될 때, 중량계(5)가 압출물(6)의 단위길이당 중량을 측정한다. 이때 측정된 중량이 관리 허용치를 벗어나게 될 경우, 컨트롤러(10)가 마킹장치(9)를 작동시켜 압출물(6)에 부적합 표시를 하게 된다.Looking at the operation of the present invention, when the extrudate 6 passed through the extruder 2 head mold portion 11 is transferred along the conveyor 4, the weight scale 5 is a unit of the extrudate 6 Measure the weight per length. At this time, if the measured weight is out of the control allowance, the controller 10 operates the marking device 9 to mark the non-conformity on the extrudate 6.

또한, 측정된 중량이 관리허용치 내에 들어올 경우, 컨트롤러(10)가 마킹장치(9)를 작동시켜 압출물(6)에 마킹되는 부적합 표시를 멈추게 된다.In addition, when the measured weight is within the allowable value, the controller 10 operates the marking device 9 to stop the display of nonconformity marked on the extrudate 6.

따라서 작업자는 생산된 압출물에서 적합구간과 부적합 구간을 별도 선별하여 타이어를 제조할 수 있는 것이다.Therefore, the operator can separate the suitable section and the non-conforming section from the produced extrudate to manufacture the tire.
