Such jet water contains various fine foreign substances, which may be supplied into the jet nozzle together with the foreign substances.

분사노즐 내로 유입된 분사수의 이물질은 분사노즐 내의 스태빌라이저 사이에 끼여 고압으로 유입되는 분사수의 집속성을 떨어뜨리고 분사속도 또한 느려지게 되어 직기가 고속화되지 못한다. 이럴 경우 분사노즐을 분리하여 이물질을 제거하여야함으로써 작동하는 직기를 멈추고 분사노즐을 분리한 후 이물질을 제거하여 다시 작동시켜야하는 불편함이 있었다.
Foreign substances in the injection water introduced into the injection nozzles are caught between the stabilizers in the injection nozzles to reduce the concentration of the injection water flowing at high pressure and the injection speed is also slowed down, so that the loom is not accelerated. In this case, it is inconvenient to stop the weaving machine by removing the foreign matter by removing the spray nozzle, remove the foreign matter, and then operate it again by removing the foreign matter.

몸체(4) 내부에 형성되는 실장부(8)에는 위사 공급을 위한 위사투입구(24)가 내부에 형성된 니들(6)이 나사결합에 의해 몸체(4) 후방에서 끼워진다. 실장부(8)에 끼워지는 니들(6)의 후방에는 몸체(4)의 실장부(8)에 니들(6)을 끼움 결합하기 위한 체결부(22b)가 구비되며, 니들(6)의 최후방에는 니들(6)을 나사 결합하기 위한 손잡이(26)부가 형성된다.In the mounting portion 8 formed inside the body 4, the needle 6 having a weft inlet 24 for supplying the weft thread is fitted in the rear of the body 4 by screwing. At the rear of the needle 6 fitted to the mounting portion 8, a fastening portion 22b for fitting the needle 6 to the mounting portion 8 of the body 4 is provided, and the end of the needle 6 is provided. In the room, a handle 26 for screwing the needle 6 is formed.

니들(6)의 선단부(28)에는 몸체(4)의 일측에 형성된 분사수유입로(10)를 통해 유입되는 분사수를 정류 및 집속하기 위한 스태빌라이저(16)가 끼워진다. 스태빌라이저(16)의 후단에는 분사수를 최종적으로 집속하여 위사투입구(24)를 통해 공급되는 위사와 함께 분사수를 분사하기 위한 수렴부재(18)가 니들(6)의 선단부(28) 끝단에 위치한다. The front end portion 28 of the needle 6 is fitted with a stabilizer 16 for rectifying and focusing the injection water flowing through the injection water inlet 10 formed on one side of the body (4). At the rear end of the stabilizer 16, a converging member 18 for discharging the sprayed water together with the weft supplied through the weft inlet 24 is finally located at the distal end 28 of the needle 6. do.

니들(6)은 후방에서 선단부(28)로 갈수록 내부 위사투입구(24)가 좁게 형성되어 있어 위사가 일직선상으로 용이하게 공급될 수 있다. 니들(6)의 선단부(28)의 일단에는 경사부가 있어 스태빌라이저(16)를 통과한 분사수가 경사부를 따라 용이하게 유도되어 분사될 수 있도록 한다.

일반적으로 워터젝트직기용 분사노즐(2)은 고압으로 분사되는 분사수에 포함된 이물질이 스태빌라이저(16)의 돌출편(34)에 누적되거나 걸려 분사수의 고속분사를 방해함에 따라 정류 및 집속력이 떨어지게 된다. 이렇듯 분사수의 정류 및 집속력이 떨어진 분사노즐(2)은 주기적으로 분리하여 이물질을 제거하여야 함에 따라 직기를 멈추어야 한다.In general, the water jet loom jet nozzle 2 has a commutation and focusing force as foreign matter contained in the jet water injected at high pressure accumulates or catches on the protruding pieces 34 of the stabilizer 16 to prevent high-speed injection of the jet water. Will fall. As such, the injection nozzle 2 having the rectification and focusing power of the sprayed water must be separated periodically to remove foreign substances, so that the loom must be stopped.

본 발명의 워터젝트직기용 분사노즐(2)은 분사수에 포함된 이물질이 스태빌라이저(16)로 유입되는 것을 차단하여 스태빌라이저(16)의 돌출편(34)에 이물질이 쌓이는 것을 방지함에 따라 직기의 연속적인 작동이 가능하다.The injection nozzle 2 for the water jet loom according to the present invention prevents foreign matters contained in the injection water from entering the stabilizer 16 to prevent foreign matters from accumulating on the protruding pieces 34 of the stabilizer 16. Continuous operation is possible.

본 발명의 실시 예에 따른 분사노즐(2)은 분사수가 공급되는 분사수유입로(10)의 일단에 분사수에 포함된 이물질을 여과하기 위한 제1 필터링부재(12)가 구비된다.The injection nozzle 2 according to the embodiment of the present invention is provided with a first filtering member 12 for filtering foreign substances contained in the injection water at one end of the injection water inflow path 10 through which the injection water is supplied.

제1 필터링부재(12)는 도 3에 도시된 바와 같이 분사수 통과 및 이물질 여과를 위한 다수의 공극이 형성된 망체이며, 공극의 크기는 스태빌라이저(16)에 형성된 돌출편(34)의 간격보다 작게 형성하여야 한다. As shown in FIG. 3, the first filtering member 12 is a mesh having a plurality of pores formed for passage of jetting water and filtration of foreign matter, and the size of the pores is smaller than an interval between the protrusions 34 formed in the stabilizer 16. It must be formed.

본 발명의 스태빌라이저(16)는 길이가 4~5mm이고 돌출편(34)의 간격은 0.5mm 이내로 형성한다. 제1 필터링부재(12) 공극의 크기를 스태빌라이저(16)의 돌출편(34) 간격보다 작거나 같게 형성함에 따라 제1 필터링부재(12)를 통과한 이물질이 스태빌라이저(16)도 통과할 수 있어 돌출편(34)에 쌓이거나 끼이지 않게 된다.The stabilizer 16 of the present invention has a length of 4 ~ 5mm and the spacing of the protruding piece 34 is formed within 0.5mm. As the size of the gap of the first filtering member 12 is smaller than or equal to the gap between the protrusions 34 of the stabilizer 16, foreign matter passing through the first filtering member 12 may also pass through the stabilizer 16. It does not accumulate or get stuck in the protruding piece 34.

본 발명의 바람직한 실시 예에서는 제1 필터링부재(12)의 공극 크기를 0.2~0.5mm로 형성하는 것이 바람직하다. In a preferred embodiment of the present invention, it is preferable to form the pore size of the first filtering member 12 to 0.2 ~ 0.5mm.

제1 필터링부재(12)의 공극 크기는 스태빌라이저(16)의 돌출편(34) 간격보다 같거나 작도록 상기의 범위 내에서 조절하여 형성하되, 공극의 크기가 하한치에 미치지 못하면 분사노즐(2) 내로 투입되는 분사수가 제1 필터링부재(12)에 부딪히는 면적이 늘어나 분사수가 저항을 많이 받으면 수압이 떨어져 분사노즐 내로의 유입이 원활하지 못하다. 또한, 공극의 크기가 상한치를 넘어서면 스태빌라이저(16)의 돌출편(34) 간격보다 크기가 큰 이물질이 제1 필터링부재(12)를 통과함에 따라 스태빌라이저(16)의 돌출편(34) 사이에 이물질이 누적되거나 끼여 분사수의 분사를 방해하게 된다.The pore size of the first filtering member 12 is formed within the above range so as to be equal to or smaller than the spacing of the protruding pieces 34 of the stabilizer 16, but if the pore size does not reach the lower limit, the injection nozzle 2 If the injection water injected into the first filtering member 12 increases the area, and the injection water receives a lot of resistance, the water pressure drops and the inflow into the injection nozzle is not smooth. In addition, when the size of the void exceeds the upper limit, foreign matter larger in size than the gap between the protrusions 34 of the stabilizer 16 passes through the first filtering member 12, and thus, between the protrusions 34 of the stabilizer 16. Foreign matter accumulates or gets stuck in the injection water jet.

제1 필터링부재(12)를 통해 1차로 여과된 분사수는 분사노즐(2) 내로 공급되면서 실장부(8)에 구비된 제2 필터링부재(14)에 의해 2차로 다시 한번 더 여과된다.The injection water primarily filtered through the first filtering member 12 is once again filtered secondly by the second filtering member 14 provided in the mounting unit 8 while being supplied into the injection nozzle 2.

도 4는 제2 필터링부재(14)의 사시도로, 본 발명의 실장부(8) 내에는 니들(6)이 끼워짐에 따라 제2 필터링부재(14)는 니들(6)이 끼워질 수 있도록 심부에 니들 끼움공(32)이 형성된다. 니들 끼움공(32)은 도 4에서와 같이 원형으로 형성되며, 도 5에서와 같이 다수의 굴곡부를 형성하여 니들 끼움공(32)에 끼워진 니들(6)의 선단부(28) 흔들림을 고정하는 것도 가능하다.4 is a perspective view of the second filtering member 14, the needle 6 is fitted into the mounting portion 8 of the present invention so that the second filtering member 14 may be fitted with the needle 6. Needle fitting hole 32 is formed in the core. The needle fitting hole 32 is formed in a circular shape as shown in FIG. 4, and as shown in FIG. 5, a plurality of bent parts are formed to fix the shaking of the tip 28 of the needle 6 inserted into the needle fitting hole 32. It is possible.

본 발명의 제2 필터링부재(14)는 제1 필터링부재(12)와 같이 다수의 작은 공극이 구비된 망체이며, 공극의 크기는 0.05~0.3mm로 형성한다. 제2 필터링부재(14)는 제1 필터링부재(12)에 의해 1차 여과된 분사수에 포함된 이물질을 2차로 여과하는 것임에 따라 공극의 크기를 상기의 범위 내에서 제1 필터링부재(12)보다 좀 더 조밀하게 형성하는 것이 바람직하다.The second filtering member 14 of the present invention, like the first filtering member 12, is a mesh provided with a plurality of small voids, and the size of the voids is formed at 0.05 to 0.3 mm. As the second filtering member 14 filters the foreign matter contained in the injection water primarily filtered by the first filtering member 12 in a second manner, the size of the pore is within the above range. It is desirable to form more densely than).

본 발명의 제1,제2 필터링부재(12)(14)는 스테인리스 소재로 형성할 수 있다.The first and second filtering members 12 and 14 of the present invention may be formed of a stainless material.

제2 필터링부재(14)는 분사수에 포함된 이물질을 2차로 여과함과 함께 니들(6)의 선단부(28)에 끼워져 분사되는 분사수를 정류하는 역할을 한다.The second filtering member 14 filters the foreign matter contained in the sprayed water in a secondary manner, and serves to rectify the sprayed water injected into the distal end portion 28 of the needle 6.

즉, 분사수유입로(10)를 통해 공급되는 분사수가 제1 필터링부재(12)를 통과하여 여과된 후 제2 필터링부재(14)에 의해 2차로 여과되는데, 이때 분사수가 분사되는 방향과 수직으로 분사수가 공급됨에 따라 분사수의 와류가 발생한다. 이러한 와류는 분사수의 직속성을 떨어뜨릴 수 있어 이를 정류하는 것이 필요하다. That is, the injection water supplied through the injection water inlet passage 10 is filtered through the first filtering member 12 and then secondarily filtered by the second filtering member 14, wherein the injection water is perpendicular to the direction in which the injection water is injected. As the injection water is supplied, vortex of the injection water occurs. These vortices can degrade the directness of the jetted water and require rectification.

본 발명에서는 분사노즐(2)의 분사방향으로부터 수직방향으로 공급되는 분사수를 1차로 정류하여 후단의 스태빌라이저(16)에 의한 분사수의 정류 및 집속이 용이하게 한다.In the present invention, the injection water supplied in the vertical direction from the injection direction of the injection nozzle 2 is rectified primarily to facilitate rectification and focusing of the injection water by the stabilizer 16 at the rear end.

분사노즐(2) 내의 분사수는 분사수유입로(10)를 통해 공급된 후 실장부(8)의 내벽에 부딪히면서 방향이 수직으로 꺾여 와류가 발생하는데, 와류가 발생한 분사수는 망체로 형성된 제2 필터링부재(14)를 통과하면서 정류가 되는 구성이다.After the injection water in the injection nozzle 2 is supplied through the injection water inflow path 10 and swivels vertically while hitting the inner wall of the mounting portion 8, vortices are generated. 2 is a configuration that is rectified while passing through the filtering member (14).

본 발명의 다른 실시 예에서는 제1,제2 필터링부재(12)(14)를 격자무늬로 짜여진 다층형태의 필터들을 구비하고 각 층의 격자무늬들이 서로 교체되게 적층형성한다. 격자무늬로 이루어진 다층의 필터들을 적층형성함에 따라 이물질 여과를 위해 공극의 크기를 미세하게 형성한 일체형의 필터들보다 분사수의 저항력을 낮추어 분사수의 수압이 떨어지지 않고 분사노즐을 통해 고속분사함과 동시에 이물질 여과도 가능한 것이다.In another embodiment of the present invention, the first and second filtering members 12 and 14 are provided with a multi-layered filter woven in a lattice pattern, and the lattice patterns of each layer are laminated to be replaced with each other. As the multilayered filters formed of lattice pattern are laminated, the resistance of the sprayed water is lowered than that of the integrated filters in which the pore size is finely formed for filtration of foreign substances. At the same time, foreign material filtration is possible.

제2 필터링부재(14)를 통과한 분사수는 니들(6)의 선단부(28)에 끼워진 스태빌라이저(16)에 의해 한번 더 정류 및 집속된다. 스태빌라이저(16)는 정류 및 집속된 분사수의 직속성을 높이기 위해 토출구로 갈수록 좁아지게 돌출편(34)이 형성되어 있다.The jetted water passing through the second filtering member 14 is further rectified and focused by the stabilizer 16 fitted to the distal end 28 of the needle 6. The stabilizer 16 is formed with a protruding piece 34 to be narrowed toward the discharge port in order to increase the directivity of the rectified and focused sprayed water.

돌출편(34)이 후미로 갈수록 좁아져 경사각을 형성함에 따라 분사수가 토출구로 집속됨과 함께 직속성을 유지하며 분사될 수 있는 것이다.As the protruding piece 34 becomes narrower toward the rear to form an inclination angle, the jetting water can be injected while maintaining the directivity while the jetting water is focused on the discharge port.

본 발명에서는 스태빌라이저(16)의 경사각을 65~70°로 형성하여 분사수가 직속성을 유지하면서 분사될 수 있도록 한다.In the present invention, the inclination angle of the stabilizer 16 is formed at 65 to 70 ° so that the sprayed water can be sprayed while maintaining directness.

스태빌라이저(16)에 의해 집속되어 분사되는 분사수는 수렴부재(18)에 의해 최종적으로 집속되어 위사투입구(24)를 통해 공급되는 위사를 견인하여 분사노즐(2)의 토출구로 분사된다.The jetted water that is focused and sprayed by the stabilizer 16 is finally focused by the converging member 18 and pulls the weft that is supplied through the weft inlet 24 to be injected into the discharge port of the jetting nozzle 2.
