본 발명은 섬유기계 특히 양말편직기의 편직과정중에 발생되는 원사의 단절과 과장력상태를 용이하게 감지하는 섬유기계용 원사이상감지장치에 관한 것으로, 더욱 구체적으로 설명하면, 기계내에 공급되는 원사의 단절과 과도한 장력을 감지할 수 있도록 원사가 기계내로 공급되는 통로상에 과장력감지기와 단락감지기가 설치되어 원사의 공급상태를 최적의 장력을 갖으면서 공급되게 하므로서 우수한 직물의 제조가 가능한 섬유기계용 원사이상감지장치에 관한 것이다.The present invention relates to a yarn abnormality detection device for a textile machine that easily detects the disconnection and exaggerated state of the yarn generated during the knitting process of the textile machine, in particular, sock knitting machine, and more specifically, the yarn supplied into the machine For the textile machinery which can manufacture excellent fabrics by installing the exaggerated tension sensor and the short circuit detector on the passage where the yarn is fed into the machine so as to detect breakage and excessive tension. It relates to a yarn abnormality detection device.

일반적으로, 섬유기계의 직조시에 원사가 끊어지거나 엉킴을 일으키게 되어도 섬유기계가 계속 작동하여 직물의 직조상태가 조악하게 되어 제품의 질을 저하시키게 되며 심할 경우에는 원단 자체를 폐기처리 시켜야 하는 문제점을 안고 있다. 이러한 문제점을 해결하기 위하여, 기존의 섬유제품을 생산하는 섬유기계는 기계적 걸림장치를 이용하여 실의 단절상태를 감지하기 때문에 해당 섬유기계의 물리적 상태인 습기로 인한 녹과, 오일의 방청 유무 등과 같은 물리적 상태에 따라서 상당한 오류를 일으킴으로 인해 정확한 원사의 방사상태를 파악하기가 어려울 뿐만 아니라 관리자가 일일이 기계에 공급되는 실의 감지상태를 파악하여야 하므로 인력과 비용낭비가 있게 되는 문제점이 있었다. 이러한 문제점을 해결하기 위하여, 원사의 끊어짐을 감지할 수 있도록 원사가 지나는 통로에 발광부와 수광부로 이루어진 센서를 설치하여 원사의 단락을 감지하는 장치가 제안된 바 있다. 그러나, 이러 한 원사의 단락을 감지하는 센서는 원사의 단락만을 감지할 뿐이고 원사가 끊어지기 전에 발생되는 과도한 긴장상태를 감지할 수 없으므로 원사가 끊어져야만 원사의 이상상태를 발견할 수 있으므로 섬유제품의 불량을 개선하는 근본적인 문제를 해결할 수 없었다는 문제점이 있었다.In general, even if the yarn breaks or entangles during the weaving of the textile machine, the textile machine continues to operate, resulting in a poor weaving state of the fabric, which degrades the quality of the product. In severe cases, the fabric itself must be disposed of. Holding it. In order to solve this problem, the textile machinery producing the existing textile products detects the disconnection state of the yarn by using a mechanical locking device, such as rust due to moisture, the presence or absence of oil rust, etc. Due to the significant error caused by the physical condition, it is difficult to determine the exact radiation state of the yarn, and there is a problem in that the manager has to grasp the detection state of the thread supplied to the machine, and there is a problem of manpower and cost. In order to solve this problem, an apparatus for detecting a short circuit of a yarn has been proposed by installing a sensor consisting of a light emitting part and a light receiving part in a passage through which the yarn passes so as to detect a broken yarn. However, the sensor that detects such a short circuit of the yarn only detects a short of the yarn and cannot detect excessive tension generated before the yarn breaks, so the yarn must be broken to detect an abnormal state of the textile product. There was a problem that the fundamental problem of improving the defect could not be solved.

본 발명의 목적은, 이러한 문제점을 해결하기 위한 것으로, 원사의 끊어진 상태인 원사의 단락상태를 감지하는 것은 물론이고 원사의 장력이 상이함으로 발생되는 제품형태와 질의 불량을 사전에 예방하게 되고 원사의 단락이전에 발생되는 과도한 긴장상태를 감지하므로서 원사의 단락을 미리 방지하여 제품의 생산성을 높이고 과도한 긴장상태를 조기에 감지하여 해결하게 되므로써 품질이 우수한 섬유제품을 제조하는 것이 가능한 섬유기계용 원사이상감지장치를 제공하는 것이다.An object of the present invention is to solve such a problem, as well as to detect the short-circuit state of the yarn in the broken state, as well as to prevent in advance the defects in product form and quality caused by different yarn tension and Detects abnormal tension occurring before short circuit, prevents short circuit of yarn in advance, increases product productivity, and detects and resolves excessive tension early to solve the abnormality of yarn for textile machinery, which makes it possible to manufacture high quality textile products. To provide a device.

When excessive tension is generated in the yarn 2 while the fibers are woven and drawn into the weaving part of the machine in this way, the yarn winding drum 1 is disposed below the exaggerated tension sensor 3 so that the yarn 2 While receiving the force downward, as shown by the two-dot chain line in Figure 2, the yarn tension cradle 31 is pressed down the free end portion 31c downward while pressing the button switch 32, the exaggerated force sensing body 33 Recognizes the exaggerated tension state of the yarn and sends the exaggerated state to the main controller 5, the main controller 5 is to stop the operation of the textile machine. In addition, when the yarn 2 is cut off during the operation of the textile machine, as shown in Fig. 1, the yarn 2 on the right side of the photointerrupter 40 is drawn into the weaving part of the machine and the photointerrupter 40 is used. Since the yarn 2 on the left side of the) does not reach the photointerrupter 40, the light emitting unit 41 and the light receiving unit 42 detect the disconnection of the yarn, and transmit the disconnection signal of the yarn to the main controller 5 so that the fiber may not reach the photointerrupter 40. The machine will stop working.
