본 고안은 래피어식 직기의 래피어 구동장치에 관한 것으로, 더욱 상세하게는 펴심캠의 회전운동을 구동기어의 좌,우 반복 회전운동으로 직접 전달하게 함으로서, 연결부위간의 누적공차를 해소함과 동시에 기기 마모율을 감소시켜 래피어의 정확한 구동이 이루어 질수 있도록한 래피어 직기의 래피어 구동 장치에 관한 것이다.The present invention relates to a rapier driving device of a rapier loom, and more particularly, by directly transmitting the rotational motion of the straight seam cam to the left and right repetitive rotational motion of the drive gear, thereby eliminating the accumulated tolerance between the connecting parts and the equipment. The present invention relates to a rapier locomotive driving apparatus of a rapier loom, which reduces the wear rate so that an accurate rapier driving can be achieved.
일반적으로 래피어 구동장치는 구동장치의 동력방향을 전환하는 구동기어에 의해 래피어 플랙시블 밴드를 일정한 행정거리로 흔들어 여러개의 레버를 통해 구동기어로 전달하여 래피어를 동작 하였던 것인바, 이같은 장치에 있어 레버를 설치하는데에 매우 정밀한 치수의 고정이 요구되고 있었던 것이며, 연결부위에서 발생되는 공차가 점차누적되어 래피어의 정확한 구동에 장애요인으로 대두되고 있음은 물론 접촉부위 역시 마모율이 증대되어 기기의 수명을 단축하게 되는등 고장의 주요원인으로 지적되고 있는 것이었다.In general, the rapier driving device operates the rapier by transferring the rapier flexible band to a predetermined stroke by a drive gear for changing the power direction of the driving device and transmitting the drive gear through a plurality of levers. In order to install the lever, it was required to fix the dimension very precisely, and the tolerances generated at the connection part gradually accumulate, which raises the obstacles to the accurate driving of the rapier and the contact part also increases the wear rate. It was pointed out as a major cause of failure, such as shortening the lifespan.
한편, 이러한 문제점을 일부 해소하고자 개량된 구동장치가 제안된 바도 있으나, 이 역시 브라켓트에 일단이 고정된 레버타측 단부에 스프링 장력을 갖는 로우프를 연결한 후 이를 구동기어와 일체로 구성된 풀리에 연결하여 캠의 회전운동을 래피어의 직선 왕복운동으로 전환케 하는 것으로, 이 경우 연결지점의 수가 다소 줄어들어 동작에 따르는 공차를 일부 감소시킬수는 있다 하더라도 근본적인 문제 해결에는 적합하지 못한 것이며 이로 인해 로우프의 장력 유지등 또 다른 문제점이 지적 되는 것이었다.On the other hand, an improved drive device has been proposed to solve some of these problems, but this also connects a rope having a spring tension to a lever-side end fixed to a bracket and then connected to a pulley integrally formed with a drive gear. It converts cam rotation into linear reciprocation of the rapier. In this case, the number of connection points is slightly reduced, which may reduce some of the tolerances due to the movement, but it is not suitable for solving the fundamental problem. Another problem was pointed out.
본 고안은 상기한 문제점을 감안하여서된 것으로서, 누적되는 공차의 해소와 마모율 감소 및 정확한 구동에 의해 래피어가 항상 일정한 행정의 왕복 직선운동을 보다 정확하게 진행할수 있도록 하는데 그 목적이 있는 것이다.The present invention has been made in view of the above problems, and the purpose is to allow the rapier to carry out the reciprocating linear motion of a certain stroke more accurately by eliminating the accumulated tolerance, reducing the wear rate, and driving accurately.
이하 본 고안을 첨부한 도면에 따라 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
즉, 제 1 도는 본 고안의 래피어 구동장치에 대한 전체구성을 보인 평면 예시도 이고, 제 2 도는 이들의 작동 상태를 도시한 작동예시도로서, 래피어 직시(도시 없음)의 구동축(1)상에 편심을 갖는 편심캠(2)이 연결되고, 래피어(7)를 좌,우 왕복직선운동 하게 하는 구동기어(3)와 편심캠(2)사이에는 캠가이드(4)와 부채꼴형의 전달기어(5)를 일체로 형성하여 고정축(6)에 결합하면 고정축(6)을 중심으로 좌,우 황복 회전이 자유롭게 된다.That is, FIG. 1 is an exemplary plan view showing the overall configuration of the rape driving device of the present invention, and FIG. 2 is an operational example showing their operating state, and the drive shaft 1 of the rapier direct view (not shown) is shown. An eccentric cam 2 having an eccentric is connected to the upper side, and a cam guide 4 and a fan-shaped fan are formed between the eccentric cam 2 and the drive gear 3 which makes the rapier 7 reciprocate linearly. When the transmission gear 5 is integrally formed and coupled to the fixed shaft 6, left and right bock rotation is freely about the fixed shaft 6.
따라서 편심캠(2)의 회전운동은, 고정축(6)을 중심으로 회전하는 캠가이드(4)를 통해 부채꼴형의 전달기어(5)로 전달되고, 부채꼴형의 전달기어(5)의 왕복 회전에 따라 구동되어(3)가 일정한 회전을 하게 되어 이와 연결된 래피어(7)를 구동케 하는 것이다.Therefore, the rotational movement of the eccentric cam 2 is transmitted to the fan-shaped transmission gear 5 through the cam guide 4 which rotates about the fixed shaft 6, and the reciprocation of the fan-shaped transmission gear 5 is carried out. Driven according to the rotation (3) is to make a constant rotation to drive the rape (7) connected thereto.
이때, 편심캠(2)과 구동기어(3)는 캠가이드(4) 및 부채꼴형의 전달기어(5)로 구성되는 단일 전달수단에 의해 구동되는 것이어서 통상의 장치에서와 같이 여러개의 전달부재가 서로 다른 지점으로 연결됨으로 인하여 초래되는 공차를 최소화 할수 있는 것이며, 상기와 같은 연결부분의 마모율을 감소시켜 이로 인한 구동상의 문제점을 해소시킬수 있음도 물론이다.At this time, the eccentric cam (2) and the drive gear (3) is driven by a single transmission means consisting of a cam guide (4) and a fan-shaped transmission gear (5) so that a plurality of transmission members as in a conventional device Tolerance caused by being connected to different points can be minimized, and the wear rate of the connection part can be reduced, thereby eliminating driving problems.
이와같이 구성된 본 고안은 제 2a 도에 도시되고 있는 바와같이 편심캠(2)의 돌출선단부가 캠가이드(4)를 외축으로 이동시킨 위치에서 부터 (b)도에 도시된 내측위치의 범위내에서 반복되는 행정으로 구동하게 되고, 부채꼴형의 전달기어(5) 또한, 고정축(6)을 중심으로 동일한 범위내의 왕복운동을 하게되어 구동축(1)의 회전운동을 구동기어(3)에 정확하고 효과적으로 변환시켜 전달할수 있는 것이다.The present invention constructed as described above repeats within the range of the inner position shown in (b) from the position where the protruding tip of the eccentric cam 2 moves the cam guide 4 to the outer axis as shown in FIG. And the fan-shaped transmission gear 5 also reciprocates within the same range around the fixed shaft 6 to accurately and effectively rotate the rotational movement of the drive shaft 1 to the drive gear 3. It can be converted and delivered.
상술한 본 고안은 래피어 직기로부터 연결되는 구동축의 동력을 구동기어에 전달하여 래피어를 구동함에 있어서, 편심캠과 구동기어간에 캠가이드 및 부채꼴형의 전달기어로 구성되는 단일의 전달수단을 이용함으로서 동작에 따르는 제반 문제점을 해소시켜 정확한 구동 및 효율적인 동력 이용은 물론 기기의 내부 수명을 한층 향상시켜 주게되는 매우 유용하고도 실용적인 효과를 갖는다.The present invention described above uses a single transmission means composed of a cam guide and a fan-shaped transmission gear between the eccentric cam and the drive gear in driving the rapier by transmitting the power of the drive shaft connected from the rapier loom to the drive gear. This eliminates all the problems associated with the operation, has a very useful and practical effect that can improve the internal life of the device as well as accurate driving and efficient use of power.
