본 고안은 주(主) 노즐의 가압공기분사에 의하여 비주(飛主)되는 위사를 보조노즐로부터의 분사에 의하여 비주를 조성(助成)하는 장치에 관한 것으로 특히 보조노즐에는 비주조성용분사공과 비주안정용 분사공을 설치하고 양공부의 분사작용에 의하여 위사의 정확한 비주를 도모하도록 한 것이다.The present invention relates to a device for forming the columnar by spraying from the auxiliary nozzle the weft threaded by the pressurized air injection of the main nozzle, and in particular, the auxiliary nozzle for injection molding and non-casting stabilization By installing the injection hole and by the injection action of the hole in the hole to achieve the correct sideline of the weft.
유체분사식 직기의 보조노즐에는 (A) 위사의 비주조성기능과(B) 위사의 비주위치 안정기능이 요구된다. (A)의 기능을 만족시키기 위하여서는 위사에 대하여 가급적 작은 각도로 취부(吹付) 시키는것이 바람직하고 또(B)의 기능을 만족시키기 위하여서는 위사에 대하여 가급적 직각방향으로 취부시키는것이 바람직하다. 그러나 사실상으로는 (B)의 기능에 있어서는 직각방향에 가까워짐에 따라서 위사가이드 사이로부터 공기가 달아나기 쉽고, 위사도 이것에 실려서 비출(飛出)되기 쉽게 된다.Auxiliary nozzles for fluid jet looms require the (A) non-casting function of weft and (B) the non-casting position stabilization function of weft. In order to satisfy the function of (A), it is preferable to mount it at the smallest angle with respect to the weft yarn, and to satisfy the function of (B), it is desirable to mount it in the direction perpendicular to the weft yarn as much as possible. However, in fact, in the function of (B), as it approaches a right angle direction, air easily escapes between the weft guides, and the weft yarns are also easily carried on it.
종래의 보조노즐은 하나의 분사공에 의하여 상기의 두가지 기능을 만족시키고저 하였으므로 분사각의 설정이 어렵고 또한 분사속도의 선정도 어렵다는 결점이 있었다. 즉 (B)의 기능을 위하여서는 위사를 위사가이드의 속 깊숙히 압입시키는 편이 좋으나 그렇게하면 (A)의 기능을 나타내기가 어렵고, 이 경우 분사속도도 고려하지 않으면 안된다.Since the conventional auxiliary nozzle satisfies the above two functions by one injection hole, it is difficult to set the injection angle and to select the injection speed. In other words, for the function of (B), it is better to press the weft deep into the inside of the weft guide, but it is difficult to express the function of (A), and in this case, the injection speed must also be taken into consideration.
본 고안은 위사의 비주조성기능과 비주위치안정 기능을 각각 더한층 높힐수 있게 하기 위하여 각각 전용의 분사공을 보조노즐에 설치하도록 한것이다.In order to further increase the non-casting function and non-casting position stabilization function of the weft, each of the dedicated injection holes are installed in the auxiliary nozzle.
특히 종래에는 상가 양기능(A), (B)를 만족시키고저 하나의 분사공을 각도적으로 선정시키고 있었으나 본 고안은 양기능에 적합한 분사속도를 얻는다는 관점에서 각각 전용의 분사공을 설치하도록 한것이다.Particularly, in the related art, both of the two functions A and B are satisfied, and the single injection hole is selected at an angle, but the present invention provides a dedicated injection hole in view of obtaining an injection speed suitable for both functions. It is.
그리하여 상기한 전용의 분사공으로 부터의 분사기류의 부닥침에 의한 난류를 방지하도록 분사공의 위치를 각도방향 및 상하방향에서 엇갈리게 설치한 것이다. 따라서 전용의 분사공은 각각의 기능에 적합한 각도, 속도로 결정할 수가 있다.Thus, the positions of the injection holes are staggered in the angular direction and the vertical direction so as to prevent turbulence caused by the impingement of the injection air stream from the above-mentioned dedicated injection holes. Therefore, a dedicated injection hole can be determined by the angle and speed suitable for each function.
또한 속도의 결정은 공경(孔徑)에 의하여 행하는 것이 최적이다.In addition, it is optimal to determine the speed by the pore diameter.
실시예를 도면에 따라서 설명하면 다음과 같다.An embodiment is described with reference to the drawings as follows.
제1도는 종래장치의 측면도, 제2도는 제1도의 요부의 평면도로서 4는 주노즐, 3은 보조노즐, 5는 위사가이드, 6은 위사비주로, 7은 위사, 8은 래이스, 9는 바디이다.FIG. 1 is a side view of a conventional apparatus, and FIG. 2 is a plan view of the main portion of FIG. 1, where 4 is a main nozzle, 3 is an auxiliary nozzle, 5 is a weiss guide, 6 is a weft yarn, 7 is a weft yarn, 8 is a race, and 9 is a Body.
제3도, 제4도는 본 고안에 의한 보조노즐 3의 기본 형태로서 비주조성기능용의 분사공 1과 비주안정기능용의 분사공 2가 각각 1개 설치되어 각도와 속도 즉 공경이 선정되고 또한 분사기류에 의한 난류를 방지하기 위하여 각도방향 및 상하방향으로 엇갈리게 설치한다. 분사공 1, 2의 상하방향의 위치는 위사가이드 5의 위사 7의 비주로 6내에 있게 된다.3 and 4 are basic shapes of the auxiliary nozzle 3 according to the present invention, and one injection hole 1 for non-casting function and one injection hole 2 for non-casting function are installed to select angle, speed, and pore diameter. In order to prevent turbulence caused by injector streams, they are alternately installed in the angular and vertical directions. The up and down positions of the injection holes 1 and 2 are located within the main line 6 of the weft yarn 7 of the weft guide 5.
주노즐 4에 의한 위사 7의 비주속도, 위사 7의 긁이등에 따라 다르나 비주조성기능용의 분사공 1의 위사 7의 비주방향과 이루는 각(제5도 참조)는 15°-25°바람직하기는 20°이고, 비주안정기능용의 분사공 2의 위사 7의 비주방향과 이루는 각(제5도 참조)는 30°-40°바람직하기는 35°이다.Angle depending on the non-circumferential direction of the weft 7 of the injection hole 1 for the non-casting function, depending on the specific speed of the weft 7 by the main nozzle 4 and the scratching of the weft 7 (See Fig. 5) is 15 ° to 25 °, preferably 20 °, and the angle formed with the non-circumferential direction of the weft 7 of the injection hole 2 for the non-stable stability function. (See Fig. 5) is 30 ° -40 ° preferably 35 °.
또한 분사속도에 대하여서는 분사공 1의 지름을 분사공 2의 지름보다도 작도록하여 분사공 1로부터의 분사속도를 분사공 2로부터의 그것보다도 더 크게하고 또한 양분사기류의 교차난류를 방지하기 위하여 분사공 1과 2는 보조노즐 3에 상하방향으로도 각도방향 방향으로도 엇갈리게 설치된다.In addition, in terms of the injection speed, the diameter of the injection hole 1 is made smaller than the diameter of the injection hole 2 so that the injection speed from the injection hole 1 is larger than that from the injection hole 2, and to prevent cross turbulence of the nutrient injection streams. The injection holes 1 and 2 are alternately installed in the auxiliary nozzle 3 in the vertical direction and the angular direction.
제6도, 제7도, 제8도는 분사공 1, 2의 개수 및 배열 및 위사 가이드의 형을 달리한 다른 실시예이다.6, 7 and 8 are other embodiments in which the number and arrangement of the injection holes 1 and 2 and the shape of the weft guides are different.
제6도는 보조노즐 3에 비주조성용의 분사공 1과 비주안정용의 분사공 2를 각각 2개씩 설치하고 상하 소경의 분사공 1, 1의 중간에 대경의 분사공 2, 2를 설치하며 또 분사공 1과 2는 보조노즐 3의 중심측에 대한 각도가 엇갈리게 되어 있다.6 is provided with two injection holes 1 for non-casting and two injection holes for non-cast stability in auxiliary nozzle 3, and two and two injection holes for large diameter in the middle of the upper and lower small diameters. 1 and 2 are staggered with respect to the center side of the auxiliary nozzle 3.
이 때문에 제3도의 것에 비하여 위사 7의 비주조성기류와 비추안정기류가 위사를 한층 더 안정화시킴과 동시에 양기류의 난류를 방지한다.For this reason, compared with FIG. 3, the non-casting and non-stabilizing airflow of the weft yarn 7 stabilizes the weft yarn further, and prevents the turbulence of the gas stream.
제7도, 제8도는 상부개구형 위사가이드 10중에 게재하는 반개구형 위사가이드 5에 대향하여 보조노즐 3을 설치한 실시예로서 상하의 소경분사공 1의 중간에 이들과 각도를 엇갈리게 대경의 분사공 2를 설치하고 있다. 이 실시예는 제8도에 표시한 바와같이 보조노즐 3이 서로 배열되어 있는 위사가이드 10의 완부에 대응하는 위치에 설치되고 그분사공 (1, 1, 2)가 위입통로에 임하고 있으므로 상기한 실시예의 효과 외에도 레이스 8 위의 구조가 치밀하게 됨과 동시에 분사기류를 유효하게 이용하는 이점도 가졌다.7 and 8 are the embodiments in which the auxiliary nozzle 3 is installed to face the semi-opening weft guide 5 placed in the upper opening weft guide 10. I install 2. As shown in Fig. 8, this embodiment is described above because the auxiliary nozzles 3 are installed at positions corresponding to the ends of the weiss guide 10 in which the auxiliary nozzles 3 are arranged, and the dead holes 1, 1 and 2 face the upper entrance passage. In addition to the effect of the example, the structure of the race 8 is more compact and has the advantage of effectively utilizing the jet stream.
본 고안은 이와같이 구성되었으므로 위사의 (A) 비주조성기능과 (B) 비주안정기능을 각기 따로 충분히 만족시킬수 있는 최량의 분사각도와 분사속도를 적정하고도 용이하게 선정할수 있음은 물론 각도적으로도 또한 상하방향으로도 분사공 1, 2를 엇갈리게 하였으므로 분사기류가 강하게 부닥치는 일이 없으므로 위사의 흐트러짐이 없다.Since the present invention is constructed in this way, it is possible to select the best injection angle and the injection speed appropriately and easily to satisfy the (A) non-casting function and (B) non-stable stability separately. In addition, since the injection holes 1 and 2 are staggered in the vertical direction, there is no disturbance of the weft because the injection airflow is not strongly encountered.
즉 위사는 주노즐에 의한 분사류(流)로 비주되고 보조노즐의 분사류가 효과적으로 조정기능과 안정기능을 발휘하여 정확하게 비주하며 정확한 위사통(通)을 행하고 직포의 품질을 향상시킬 수가 있다.In other words, the weft yarn is primed by the jet flow by the main nozzle, and the jet flow of the auxiliary nozzle effectively adjusts and stabilizes, so that the weft thread can be accurately pinched, perform the precise weft barrel, and improve the quality of the woven fabric.
또한 보조노즐 3에 설치되는 분사공 1과 분사공 2의 수 및 그조합에 대하여서는 상기한 실시예에 한정되는것이 아니며 본 고안의 취지의 범위내에서 임의로 선택할 수가 있다.In addition, the number of injection holes 1 and injection holes 2 and combinations thereof provided in the auxiliary nozzle 3 is not limited to the above-described embodiment, and may be arbitrarily selected within the scope of the present invention.
또 위사가이드의 형상에 대하여서도 상기의 실시예에 한정되는 것이 아닌바 예컨대 바디와 일체가 되도록 형성된 소위 변형바디도 가능하다.In addition, the shape of the weiss guide is not limited to the above-described embodiment, for example, a so-called deformed body formed to be integral with the body is also possible.
