환편기의 송사휠 구동장치{Apparatus for driving yarn supply wheel in circular knitting machine}Apparatus for driving yarn supply wheel in circular knitting machine}

본 발명은 환편기의 송사휠에 관한 것으로, 더 상세하게는 송사휠을 구동시키는 구조를 간단하게 개선하여 조립성을 향상시키고, 또한 송사휠과 편직부의 회전속도가 항상 일정하게 유지되도록 하여 편직물의 품질을 향상시킬 수 있도록 한환편기의 송사휠 구동장치에 관한 것이다.The present invention relates to a feeder wheel of a circular knitting machine, and more particularly, to improve the assembly by simply improving the structure for driving the feeder wheel, and also to ensure that the rotational speed of the feeder wheel and the knitting portion is always maintained at a constant quality It relates to a death wheel driving device of the circular knitting machine to improve the.

일반적으로 환편기에 있어서 편직물 편성시 사용하는 실의 급사속도는 가변하는 편직부의 회전속도에 따라서 일정비율로 공급되어야 하므로, 편직부의 회전에 따라서 정확한 비율로 회전하는 송사휠이 각 급사구 마다 강제적인 급사역할을 담당하는 실공급기와 타이밍벨트로 연결되어 이 실공급기를 구동시킨다.In general, in the circular knitting machine, the yarn feeding speed of the yarn used for knitting is to be supplied at a constant rate according to the rotational speed of the variable knitting portion, so that the yarn wheel rotating at the correct rate according to the rotation of the knitting portion is forced to feed each feeding hole. This thread feeder is connected to a thread feeder that plays a role and a timing belt.

즉, 도 1에서와 같이 송사휠(1)은 환편기의 원형지지링(2)에 설치되어 니들(바늘)로 실을 공급하여주는 다수개의 실공급기(3)들을 구동시켜주는 것으로, 송사휠(1)과 실공급기(3)는 타이밍벨트(4)로 연결된다. 이때, 송사휠(1)에는 타이밍벨트(4)의 적절한 장력을 조절하기 위한 장력조절수단이 설치되고, 송사휠(1)의 중앙에는 구동축(1a)이 축설된다.That is, as shown in Figure 1, the feed wheel (1) is installed in the circular support ring (2) of the circular knitting machine to drive a plurality of thread feeders (3) for supplying a thread to the needle (needle), 1) and the thread feeder 3 are connected to the timing belt 4. At this time, the transmission wheel (1) is provided with a tension adjusting means for adjusting the appropriate tension of the timing belt (4), the drive shaft (1a) is arranged in the center of the transmission wheel (1).

이러한 송사휠(1)은 도 2a와 도 2b에서와 같이 싱글타입과 더블타입이 있으며, 이때 송사휠(1)의 회전매개체는 편직부와 연결된 다수개의 기어(G)들을 기계적으로 연결하여 송사휠(1)을 구동시켰다.Such a death wheel 1 has a single type and a double type as shown in FIGS. 2A and 2B. In this case, the rotation medium of the death wheel 1 mechanically connects a plurality of gears G connected to the knitting part. (1) was driven.

따라서, 종래에는 기어(G)들의 연결을 위한 기계적인 연결구조가 복잡하여 가공과 조립이 불편한 문제점이 있었으며, 또한 이러한 기계적 연결구조는 편직물편성을 위한 가동 또는 정지시에 발생하는 기계적인 충격으로 편직부와 송사휠(1)사이에 연결된 기어(G)들간의 간격으로 인한 흔들임을 발생시켜 최종적인 송사휠(1)과의 회전비율에 차이가 생겨 정확한 비율의 급사속도를 만들지 못하므로 결과적으로 그 영향이 편직물상에 미쳐 편직물의 품질에 좋지 않은 결과를 만들어 내는 문제점이 있었다.Therefore, in the related art, the mechanical connection structure for the connection of the gears G is complicated, and thus there is a problem in that processing and assembly are inconvenient. In addition, such a mechanical connection structure is modified by a mechanical shock generated during start or stop for knitting. The shaking caused by the gap between the gears (G) connected between the direct part and the killing wheel (1) causes a difference in the rotational ratio with the final killing wheel (1). There was a problem that the influence on the knitted fabric, which results in poor quality of the knitted fabric.

본 발명의 목적은 상기에서와 같은 종래의 결점을 해소하기 위해 발명한 것으로, 송사휠을 구동시키는 구조를 간단하게 개선하여 조립성을 향상시키고, 또한 송사휠과 편직부의 회전속도가 항상 일정하게 유지되도록 하여 편직물의 품질을 향상시킬 수 있도록 한 환편기의 송사휠 구동장치를 제공하는 데 있다.An object of the present invention is to invent the conventional drawbacks as described above, to improve the assembly by simply improving the structure for driving the pine wheel, and also to maintain a constant rotation speed of the pine wheel and the knitting portion at all times The present invention provides a circular wheel driving device for a circular knitting machine to improve the quality of the knitted fabric.

상기 목적을 달성하기 위해 본 발명은 편직부와 송사휠의 기어들을 통한 기계적인 연결구조를 없애고 송사휠을 모터로 직접 구동시키되, 송사휠을 구동시키는 모터에 편직부의 회전속도값을 측정하여 이 값에 따라서 편직부와 송사휠의 회전속도 비율을 항상 일정하게 유지시키는 회전감지센서,컨트롤러를 전기적으로 연결한 것이다.In order to achieve the above object, the present invention eliminates the mechanical connection structure through the gears of the knitting part and the feeding wheel, and drives the feeding wheel directly with the motor, and measures the rotational speed value of the knitting part in the motor driving the feeding wheel. According to this, the rotation sensor and controller are electrically connected to keep the ratio of the rotational speed of the knitting part and the feeder wheel always constant.
