도면의 미설명부호 50은 바듸프레임, 51은 바듸살, 52는 고정볼트, 53은 사도홈, 54는 위사, 55는 공기호스연결구를 표시한 것이다.In the drawings, reference numeral 50 is a bar frame, 51 is a bark, 52 is a fixing bolt, 53 is an apostle groove, 54 is a weft yarn, 55 is an air hose connector.

이상과 같이 구성된 본 발명에 의한 에어제트 직기의 얀 스트레치 시스템에 관한 작용을 상세하게 설명하면 다음과 같다.Referring to the operation of the yarn stretch system of the air jet loom according to the present invention configured as described above in detail as follows.

우선, 본 발명에 의한 에어제트 직기의 얀 스트레치 시스템을 설치함에 있어서, 본체(30)의 하부에는 고정부(31)를 바듸프레임(50)에 고정볼트(52)로 설치하고 공기호스연결구(55)에 에어호스를 연결한다.First, in installing the yarn stretch system of the air jet loom according to the present invention, the fixing part 31 is installed at the lower part of the main body 30 as a fixing bolt 52 on the change frame 50, and the air hose connector 55 Connect air hose to).

상기와 같이 설치함에 있어 본체(30)의 상부에 형성된 위사흡입구(2)가 길게 형성된 돌출부(1)를 사도홈(53)에 밀착되게 설치되기 때문에 설치하는 위치를 쉽고 간편하게 바꿔줄 수 있다.In the installation as described above, because the weft suction port 2 formed in the upper portion of the main body 30 is installed in close contact with the projection groove (53) formed long can be easily and easily change the installation position.

또한, 이러한 과정에서 바듸살과 무관하게 되므로 바듸살이 손상되는 것을 방지할 수 있는 것이다.In addition, in this process, it is irrelevant to the bark, so it is possible to prevent the bark from being damaged.

상기와 같이 설치하여 직물원단을 제직할 때 얀 스트레치 시스템의 작용을 살펴본다.Examine the action of the yarn stretch system when weaving the fabric by installing as described above.

에어제트 직기를 구성하는 급사장치로부터 송출되는 위사(54)는 돌출부(1)의 내부에 형성된 위사흡입구(2)에서 위사를 흡입하여 배출하게 된다.The weft yarn 54 sent from the yarn feeding device constituting the air jet loom sucks the weft yarn from the weft suction opening 2 formed in the protrusion 1 and discharges it.

더 구체적으로는 에어제트 직기를 구동하게 되면, 공지의 작용에 의해서 공기공급관(32)을 통해 유입된 공기가 벤츄리관체(20)를 구성하는 공간부(22)전체로 진입하여 지지편(24)사이에 형성된 공기통로(23)들을 통해서 위사흡입구(2)의 후미로 배출된다.More specifically, when driving the air jet loom, the air introduced through the air supply pipe 32 by a known action enters the entire space portion 22 constituting the venturi pipe body 20, the support piece 24 It is discharged to the rear of the weft suction port (2) through the air passages (23) formed between.

상기와 같은 작용을 하게 되면, 공기공급관(32)을 통해 유입된 공기가 벤츄리관체(20)에 구성하는 지지편(24)에 의해서 좁게 형성된 공기통로(23)를 지나면서 공기가 빠른 속도로 이동하면서 위사흡입구(2)의 후미로 배출된다.If the above action, the air flowing through the air supply pipe 32 is passed through the air passage 23 narrowly formed by the support piece 24 constituting the venturi tube 20, the air moves at a high speed While being discharged to the rear of the weft suction port (2).

상기와 같이 공기가 빠른 속도로 이동하는 작용에 의해서 위사흡입구(2)와 벤츄리관체(20)의 위사흡입구통로(25)에 공기를 빠른 속도로 흡입하고 배출하는 작용을 하게 된다.By the action of moving the air at a high speed as described above is to act to inhale and discharge the air at a high speed in the weft suction inlet passage (25) of the weft inlet (2) and the venturi tube 20.

한편, 에어제트 직기를 구성하는 급사장치로부터 송출되는 위사(54)는 바듸살에 형성된 사도홈(53)을 지나서 최종에는 얀 스트레치 시스템을 구성하는 돌출 부(1)의 내부에 형성된 위사흡입구(2)에 도달하고 상기 벤츄리관체(20)의 흡입력에 의해서 위사가 흡입되어 위사흡입구(2)의 후미로 배출된다.On the other hand, the weft yarn 54 sent from the yarn feeding device constituting the air jet loom passes through the apostle groove 53 formed in the bark, and finally weft suction inlet (2) formed inside the protrusion (1) constituting the yarn stretch system ) And the weft yarn is sucked by the suction force of the venturi tube body 20 and discharged to the rear of the weft suction port 2.

이러한 작용을 반복함으로써 급사장치로부터 송출되는 위사를 스트레치하여 직물원단을 제직한다.By repeating such an operation, the weft yarn sent from the yarn feeding device is stretched to weave the fabric fabric.

상기와 같이 위사를 위사흡입구에서 흡입하는 과정에서 위사흡입구(2)의 선단부(3)가 본체의 측면(33)보다 돌출되어 있기 때문에 급사장치로부터 위사를 가지고 오는 공기가 본체(30)의 측면(33)에 부딪치면서 와류현상을 발생시키는 것을 방지하여 위사가 위사흡입구로 원활하게 진입하고 배출될 수 있도록 하는 작용을 하게 된다. As the tip 3 of the weft suction port 2 protrudes from the side surface 33 of the main body in the process of sucking the weft yarn at the weft suction port as described above, the air that brings the weft yarn from the yarn feeding device to the side surface of the main body 30 ( 33) prevents the occurrence of vortex phenomena, so that the weft thread enters and exits the weft inlet smoothly.
