Description
본 발명은 래디얼타이어의 구성재료인 스틸벨트를 절단하는 장치에 관한 것으로, 특히 직선나이프의 고정 및 교체에 따른 작업 중단시간을 최소화하여 작업 능률을 향상시키도록 된 스틸벨트 절단용 나이프의 고정구조에 관한 것이다.The present invention relates to an apparatus for cutting a steel belt, which is a constituent material of a radial tire, and more particularly, to a fixing structure of a knife for cutting a steel belt to improve work efficiency by minimizing downtime due to fixing and replacing a straight knife. It is about.
일반적으로 래디얼 타이어의 종류에 따라 각각의 규격에 맞는 스틸벨트의 폭 및 각도가 요구되는데, 이러한 스틸벨트의 규격에 따라 스틸벨트를 절단하는 작업은 재단공정에서 이루어지게 된다.In general, the width and angle of the steel belt according to the specifications are required according to the type of radial tire, the work of cutting the steel belt according to the specifications of the steel belt is made in the cutting process.
이 재단공정에서 사용되는 절단기의 형태를 살펴보면 크게 수직커터(Guillotine Cutter)와 원형커터(Rotary Cutter)로 나누어 볼 수 있는데, 여기서 상기 원형커터에 대해 좀 더 자세히 살펴보면 도 4에서 보는 바와 같이, 상부에 구비된 원형나이프홀더(101)에 원형나이프(102)가 장착되고, 이 원형나이프(102)의 하부에 구비된 상부홀더(103)와 하부홀더(104) 사이에 직선나이프(105)가 다수개의 볼트(106)에 의해 고정되는 구조로 이루어진다.Looking at the shape of the cutting machine used in this cutting process can be divided into a vertical cutter (Guillotine Cutter) and a circular cutter (Rotary Cutter), if you look at the circular cutter in more detail as shown in Figure 4, A circular knife 102 is mounted on the provided circular knife holder 101, and a plurality of linear knives 105 are provided between the upper holder 103 and the lower holder 104 provided at the lower part of the circular knife 102. It is made of a structure that is fixed by the bolt 106.
한편, 타이어 제조 설비공정에서 타이어의 품질에 큰 영향을 미치는 스틸벨트의 폭 정도를 좌우하는 것은 원형나이프(102)와 직선나이프(105)의 갭(Gap)조정인데, 이에 따라 주기적인 원형나이프(102) 및 직선나이프(105)의 교환은 필수적이라 할 수 있겠다.On the other hand, in the tire manufacturing equipment process, the degree of width of the steel belt, which greatly affects the quality of the tire, is determined by adjusting the gap between the circular knife 102 and the straight knife 105. 102 and the exchange of the straight knife 105 may be necessary.
그런데 절단장치의 설비구조상 원형나이프(102)는 4개의 볼트로 체결되어져 있기 때문에 교체 및 고정작업이 수월한 반면, 직선나이프(105)의 경우에는 상당수(44개)의 볼트를 해체 및 조립해야 교환작업이 이루어지도록 구성되어 작업이 불편하고 시간이 오래 걸리기 때문에 작업 능률이 저하되는 문제점이 있었다.However, because of the structure of the cutting device, the circular knife 102 is easy to replace and fix because it is fastened with four bolts, while in the case of the straight knife 105, a large number (44) of bolts must be dismantled and assembled for replacement work. There is a problem that the work efficiency is reduced because the work is inconvenient and takes a long time is configured to be made.
이에 본 발명은 상기와 같은 문제점을 해결하기 위해 발명된 것으로, 직선나이프의 교체 및 고정작업이 손쉽고 빠른 시간 내에 이루어질 수 있도록 구성되어 작업능률을 향상시킬 수 있도록 된 스틸벨트 절단용 나이프의 고정구조를 제공하는데 그 목적이 있다.Accordingly, the present invention has been invented to solve the above problems, it is configured so that the replacement and fixing work of the straight knives can be made easily and quickly within a fixed structure of the knife for cutting the steel belt to improve the work efficiency The purpose is to provide.

이하 본 발명을 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 직선나이프 고정부재가 설치된 모습을 도시한 스틸벨트 절단장치의 개략적 측면도이고, 도 2는 도 1의 직선나이프 고정부재가 상부로 이동한 상태를 도시한 스틸벨트 절단장치의 개략적 측면도이며, 도 3은 도 2에서 직선나이프 교체 후 고정부재가 하부로 이동된 상태를 도시한 스틸벨트 절단장치의 개략적 측면도이다.1 is a schematic side view of a steel belt cutting device showing a straight knife fixing member installed in accordance with the present invention, Figure 2 is a steel belt cutting device showing a state in which the straight knife fixing member of FIG. Figure 3 is a schematic side view, Figure 3 is a schematic side view of a steel belt cutting device showing a state in which the fixing member is moved to the bottom after replacing the straight knife in FIG.
본 발명은 상부에 구비된 원형나이프홀더에 원형나이프가 장착되고, 이 원형나이프의 하부에 구비된 상부홀더와 하부홀더 사이에 직선나이프가 다수개의 볼트에 의해 고정되는 구조로 이루어진 스틸벨트 절단장치에 있어서, 상기 직선나이프(5)가 안착/고정되는 상부홀더(3)의 일측에 경사면(3a)이 형성되고, 이 상부홀더(3)의 경사면(3a)과 대향되는 경사면(6b)이 형성된 고정부재(6)가 구비되며, 이 고정부재(6)의 하부에 형성된 연장부(6a)와 실린더(7)의 로드(7a)가 연결되어 이루어진다.The present invention is a circular knife holder is provided in the circular knife is provided on the top, and between the upper holder and the lower holder provided in the lower portion of the circular belt is a steel belt cutting device made of a structure fixed by a plurality of bolts In this case, the inclined surface 3a is formed on one side of the upper holder 3 on which the straight knife 5 is seated / fixed, and the inclined surface 6b is formed to face the inclined surface 3a of the upper holder 3. The member 6 is provided, and the extension part 6a formed in the lower part of this fixing member 6 and the rod 7a of the cylinder 7 are connected.
이하 본 발명에 따른 스틸벨트 절단장치의 직선나이프(5) 교체작업을 상세히 설명한다.Hereinafter, the operation of replacing the straight knife 5 of the steel belt cutting device according to the present invention will be described in detail.
먼저 상기 직선나이프(5)의 교체가 필요한 경우 상기 실린더(7)를 작동시키게 되면, 이 실린더(7) 로드(7a)의 확장에 의해 고정부재(6)가 상방으로 상승하게 되고, 이 고정부재(6)의 상승으로 인해 상부홀더(3) 일측의 구속력이 해제됨에 따라 이 상부홀더(3)가 하부홀더(4)로부터 분리 가능하게 되며, 이 분리된 상부홀더(3)로부터 교체하고자 하는 직선나이프(5)를 제거한 후 새로운 직선나이프(5')를 갈아 끼운 후, 상기 실린더(7)를 수축시키면 전술한 방향의 역방향으로 실린더(7)의 로드(7a)가 수축하게 되고, 이 실린더(7)의 수축에 따라 고정부재(6)가 하강되면서 이 고정부재(6)의 경사면(6b)이 상부홀더(3)의 경사면(3a)과 맞닿으면서 상부홀더(3)를 하부홀더(4) 쪽으로 밀어붙이는 힘을 가하게 되어 상기 직선나이프(5')가 상부홀더(3)와 하부홀더(4) 사이에서 단단히 고정된다.First, when the cylinder 7 is operated when the linear knife 5 needs to be replaced, the fixing member 6 is raised upward by the expansion of the rod 7a of the cylinder 7, and the fixing member As the restraining force of one side of the upper holder 3 is released due to the rise of 6, the upper holder 3 is detachable from the lower holder 4, and the straight line to be replaced from the separated upper holder 3 is After removing the knife 5 and replacing the new straight knife 5 ', the cylinder 7 is contracted so that the rod 7a of the cylinder 7 shrinks in the opposite direction as described above. 7, the inclined surface 6b of the fixing member 6 is in contact with the inclined surface 3a of the upper holder 3 while the fixing member 6 is lowered according to the contraction of the upper holder 3. The straight knife 5 'is firmly connected between the upper holder 3 and the lower holder 4 It is fixed.
이상 설명한 바와 같이 본 발명에 따르면, 실린더에 의해 작동되는 고정부재에 의해 직선나이프의 교체작업을 간편하게 수행할 수 있으며, 교체에 필요한 작업시간도 단축되어 전체적으로 작업 능률을 향상시키는 효과가 있다.As described above, according to the present invention, the replacement operation of the straight knives can be easily performed by the fixing member operated by the cylinder, and the work time required for the replacement is also shortened, thereby improving the overall work efficiency.
