Description

워터제트직기의 위사 홀딩장치{yarn holding system of water jet loom}Yarn holding system of water jet looms {yarn holding system of water jet loom}

본 고안은 물의 분사를 이용하여 위사를 공급하고 공급된 위사를 절단시키기 위하여 위사를 홀딩시키는 워터제트직기의 위사 홀딩장치에 관한 것으로, 위사의 홀딩장치를 개선하여 캐치코오드사 및 그 구동장치가 필요 없도록 하므로 절단해 버리는 위사의 량을 줄이고, 위사의 굵기가 동일하도록 하는 것이다.The present invention relates to a weft holding device of a water jet loom for supplying the weft yarn by using water injection and holding the weft yarn in order to cut the supplied weft yarn. The catch cord yarn and its driving device are needed by improving the holding device of the weft yarn. It will be to reduce the amount of weft to cut, so that the thickness of the weft is to be the same.

종래 워터제트직기의 위사 공급 및 홀딩은 먼저 워터제트직기 일측에 설치된 노즐에서 물의 분사에 의해 위사가 노즐의 반대편으로 최대한 신장되었다가 일정길이만큼 다시 원복되어 캐치코오드사에 의해 고정되며, 고정된 위사는 위사 감지구에 감지된 후 커터기에 의해 위사가 절단되고 절단된 위사는 전방프레임에 장치된 스핀들 장치에 의해 절단된 위사와 캐치코오드사가 꼬임운동을 하여 배출되도록 이루어진다.The weft supply and holding of the conventional water jet loom is first stretched to the opposite side of the nozzle by spraying water from the nozzle installed on one side of the water jet loom, and then undulated again by a predetermined length and fixed by the catch cord yarn. After the yarn is detected by the weft detector, the weft yarn is cut by the cutter, and the weft yarn cut is made by twisting the weft yarn and the catch cord yarn cut by the spindle device installed in the front frame.

상기와 같이 공급되는 위사는 물의 분사 압력에 따라 위사가 캐치코오드사에 정확히 위치하지 못하여 기계 가동률을 저하시키는 문제가 있었다.The weft supplied as described above had a problem in that the weft yarn was not accurately positioned in the catch cord yarn according to the injection pressure of water, thereby lowering the machine operation rate.

또한 물과 같이 분사되는 위사는 최대한 신장이 되었다가 일정 길이만큼 원복되어 캐치코오드사에 고정되어 절단 하므로 절단되는 위사의 길이가 비교적 길어 위사 소모량이 많아질뿐 아니라 위사의 일정부분에 보풀이 생기며 또한 위사의 장력이 일정치 않아 위사의 처음과 끝의 굵기가 다른 문제점이 있었다.In addition, the weft that is sprayed with water is stretched as much as possible and then circumvented by a certain length and fixed to the catch cord yarn so that the length of the weft to be cut is relatively long. Since the tension of the weft is not constant, there was a problem that the thickness of the beginning and end of the weft is different.

또한 위사를 고정하기 위한 캐치코오드사에 꼬임운동을 부여하는 스핀들장치가 전방프레임에 장치되어 장치가 복잡할뿐 아니라 절단된 위사를 고정하고 배출시키기 위한 캐치코오드사를 버리는 등의 많은 경제적인 손실을 일으키는 문제점들이 있었다.In addition, the spindle device that gives twisting motion to the catch cord yarn for fixing the weft yarn is installed in the front frame, which is not only complicated, but also saves many economic losses such as discarding the catch cord yarn for fixing and discharging the cut weft yarn. There were problems that caused them.

본 고안은 종래 문제점들을 해결하기 위하여, 워터제트직기의 노즐에서 공급되는 위사가 바디프레임에 구비되는 홀더에 위사의 끝부분이 곧바로 삽입되어 홀딩되고 커터에 의해 잘리도록 하므로 위사의 잘려나가는 부분이 짧아져 위사의 소모량이 줄어들고, 실을 꼬는 스핀들뭉치와 캐치코오드사가 필요치 않도록 하므로 장치가 간결하고 기계 가동률이 향상되도록 하며, 위사가 처지지 않고 곧바로 팽팽하게 유지되는 상태에서 위사가 홀딩되므로 보풀이 생기지 않고 위사의 처음과 끝의 굵기가 일정하도록 하는 워터제트직기의 위사 홀딩장치를 제공하는데 그 목적이 있다.In order to solve the conventional problems, the weft supplied from the nozzle of the water jet loom, so that the end of the weft is inserted into the holder provided in the body frame is immediately inserted and held by the cutter so that the cut out portion of the weft is short It reduces the consumption of weft yarns, eliminates the need for thread bundles of spindles and catch cord yarns, which results in concise and improved machine utilization. It is an object of the present invention to provide a weft holding device of a water jet loom such that the thickness of the beginning and end of the weft is constant.

여기에서, 밀대(10)는 끝단부가 하향으로 절곡되고 분사되는 물을 분산시키기 위한 장방형의 홈(13)이 끝단부 내측면(12)과 외측면(11) 사이에 형성된다.Here, the push rod 10 has a rectangular groove 13 for dispersing the water sprayed downward and the end is downwardly formed between the end inner surface 12 and the outer surface 11.

이러한 밀대(10)는 밀대(10)가 홀더(20)의 절개부(a)로 삽입되면 위사(7)가 밀대(10)의 외측면(11)에 의해 양 밀판(21) 사이로 밀려 들어가도록 하고, 양 밀판(21)에 밀착된 절단된 위사(7)가 밀대(10)의 내측면(12)에 의해 홀더(20)에서 배출되도록 하며, 노즐에서 분사되는 물이 장방형의 홈(13)에 의해 분산되게 된다.The push rod 10 is the push rod 10 is inserted into the incision (a) of the holder 20 so that the weft thread 7 is pushed between the two push plates 21 by the outer surface 11 of the push rod 10. And, the cut weft (7) in close contact with both the sealing plate 21 is discharged from the holder 20 by the inner surface 12 of the rod 10, the water sprayed from the nozzle is a rectangular groove 13 To be dispersed.

홀더(20)는 슬리트형 절개홈(25)이 상면 에 형성된 기판(24)이 바디프레임(2)에 고정되도록 되며, 전면에 길게 슬리트형 절개부(a)가 형성되는 본체 외곽부가 기판(24) 외곽부에 나사에 의해 고정되도록 되고, 본체 내부에 위치되는 한 쌍의 지지구(23)가 소정 간격을 두고 기판(24)에 고정되고, 한 쌍의 밀판(21)이 지지구(23)에 의해 대칭되게 지지되고, 상기 밀판(21)의 배면이 각기 코일스프링(22)에 탄지되어 양 밀판(21)의 전면이 서로 밀착되는 상태를 유지하게 된다.The holder 20 has a substrate 24 having a slit-shaped cutout 25 formed thereon and fixed to the body frame 2, and an outer portion of the main body having a slit-shaped cutout a formed on the front surface of the substrate 24. The outer periphery is fixed by screws, and a pair of supports 23 positioned inside the main body are fixed to the substrate 24 at predetermined intervals, and the pair of contact plates 21 are supported by the supports 23. It is symmetrically supported by, the back surface of the contact plate 21 is held by the coil spring 22, respectively, to maintain a state in which the front surfaces of both contact plates 21 are in close contact with each other.

이러한 홀더(20)는 밀대(10)가 절개부(a)로 삽입되면 위사(7)가 밀대(10)의 외측면(11)에 의해 양 밀판(21) 사이로 밀려 들어가도록 하고, 코일스프링(22)의 탄력에 의해 위사(7)가 양 밀판(21) 사이에 홀딩되게 되며, 이동하는 동안 밀대(10)의 하단부가 기판(24)의 절개홈(25)에 수납되어 간섭을 받지 않게 된다.When the holder 10 is inserted into the incision (a), the holder 20 allows the weft yarn 7 to be pushed between the two plates 21 by the outer surface 11 of the holder 10, and the coil spring ( Due to the elasticity of 22, the weft yarns 7 are held between the two plates 21, and the lower end of the holder 10 is stored in the cutout groove 25 of the substrate 24 so as not to be interfered with during the movement. .

한편, 커터(4)는 가위형태의 칼날들이 구비되고, 링크와 링크구동장치(5)에 의해 칼날들이 회전이동되도록 되어, 위사감지구(3)에서 감지신호를 받은 제어장치가 링크구동장치를 구동시켜 양 칼날 사이에 위치되는 위사를 자르도록 된다.On the other hand, the cutter (4) is provided with scissors in the form of scissors, the blades are rotated by the link and the link driving device (5), so that the control device receiving the detection signal from the weft sensing region (3) is a link driving device Drive to cut the weft between the two blades.

그리고 위사가 절단된 후 바디프레임(2)이 하단의 회전중심을 중심으로 회전이동하게 되면 바디프레임(2)과 함께 홀더(20)가 전방프레임(1)의 맞은 편으로 회전이동하게 되어 홀더(20)의 절개부(a)에서 밀대(10)가 이탈되게 된다.When the weft thread is cut and the body frame 2 is rotated about the center of rotation of the lower end, the holder 20 together with the body frame 2 is rotated to the opposite side of the front frame 1 so that the holder ( The push rod 10 is separated from the cutout a of 20).

이러한 본 고안은 위사의 끝부분이 바디프레임에 고정되는 홀더와 전방프레임에 장치되는 밀대에 의해 곧바로 삽입되어 홀딩되고 커터에 의해 잘리도록 하므로 위사의 잘려나가는 부분이 짧아져 위사의 로스가 줄어들게 되며, 실을 꼬는 스핀들뭉치와 캐치코오드사가 필요치 않도록 하므로 장치가 간결하고 기계가동률이 향상되도록 하여 막대한 경제적 이득을 득할 수 있다.The present invention is that the end of the weft is inserted by the holder that is fixed to the body frame and the front frame is immediately inserted and held by the cutter to be cut by the cutter, so that the cut portion of the weft is shortened to reduce the loss of the weft, This eliminates the need for thread bundles of spindles and catch cord yarns, resulting in concise and improved machine uptime, resulting in huge economic benefits.

또한, 위사가 처지지 않고 곧바로 팽팽하게 유지되는 상태에서 위사가 홀딩 되므로 위사의 처음과 끝의 굵기가 일정하게 되고 보풀이 없어져 제품의 품질을 향상시킬 수 있는 잇점이 있다.In addition, since the weft yarn is held in a state in which the weft yarn is kept taut immediately without being sag, the thickness of the beginning and the end of the weft yarn is constant and the lint is eliminated, thereby improving the quality of the product.
