본 고안은 압축공기 분사류를 이용하여 위사를 공급하는 젯트직기에 있어서, 특히 위사가 자연적으로 풀어지거나 꼬이지 않도록 하여 경사사이의 개구로 원활하게 공급되도록 한 에어젯트직기 의 위사공급장치에 관한 것이다.The present invention relates to a weft feeding device for an air jet weaving machine, in which a jet loom is supplied to the weft yarn by using a compressed air jet stream, and in particular, the weft yarn is smoothly supplied to the opening between the inclinations so that the weft yarn is not naturally loosened or twisted.
일반적으로 개구된 경사사이에 공기 분사류에 의하여 위사를 삽입하는 에어젯트직기에 있어서는 주노즐의 공기분사류만으로는 위사를 충분한 속도로 멀리까지 날릴 수가 없기 때문에 바디틀에 적당한 보조노즐을 설치하여 주분사류와 협동시키는 장치가 사용되고 있으나, 이러한 장치는 직기의 직성(織成)타이밍에 동조하여 보조노즐을 단계적으로 분사시키도록 되어 있기 때문에, 직조를 시작하여 어느 정도의 천이 형성될 때까지 저속운전하는 경우라든가 위사가 끊어져 보수할 경우 재운전시 실이 통과하는 것을 볼 경우 기대(機臺)를 천천히 운전시켜주게 되면 위사가 주노즐에 의하여 정상운전상태와 동일한 고속으로 북입구내의 분출되나 직기가 계속하여 운전되지 않게되므로 보조노즐의 분사타이밍이 위사의 비주(飛走)타이밍보다 늦어져서 보조노즐의 분사효과가 격감되고, 그에 따라 위사의 속도가 급속하게 떨어져 도중에서 정지한다든가 보조노즐에 걸려서 위사를 넣을 때 미사가 생긴다는 문제점이 있었고, 특히 이러한 문제점은 보빈으로부터 풀려나오는 위사가 반력이 생겨 주노즐을 이용하여 위사를 공급하기가 더 곤란해지게 되는 현상을 야기시키게 되는 것이다.In general, in the air jet loom which inserts the weft thread by the air jet flow between the opening slopes, the air nozzle flow of the main nozzle cannot fly the weft thread far enough at a sufficient speed. A device for cooperating is used, but such a device is designed to inject a sub-nozzle step by step in synchronism with the weaving timing of the loom. Therefore, when we start the weaving and operate at low speed until a certain amount of cloth is formed. If the weft is broken and repaired, if you see the thread passing during re-operation, if you operate the expectation slowly, the weft is ejected in the north entrance by the main nozzle at the same high speed as the normal operation state, but the loom continues to operate. Since the injection timing of the auxiliary nozzle is later than the non-timing timing of the weft, There was a problem that the spraying effect of the auxiliary nozzle was reduced and accordingly, the weft speed dropped so that it stopped in the middle, or the silt occurred when the weft was caught by the auxiliary nozzle. This will cause the phenomenon that it becomes more difficult to supply the weft yarn using the main nozzle.
이러한 문제점 즉 보빈으로 풀려나오는 위사의 반력을 해결하기 위하여서 보빈으로부터 풀려나오는 위사를 측정드럼에 너슨하게 감겨지게 하고 축장드럼에서 풀려나온 위사는 압축공기에 의해 U자형 저장파이프에 무부하상태로 1회 사용분만 저장되게 하여서, 주노즐의 흡인력에 의해 그리퍼가 개방됨과 동시에 U자형 파이프에 무부하상태로 있던 위사가 직물의 개구속으로 분사되도록 한 장치가 있었으나, 이러한 장치는 직물의 폭에 따라 미리 측장드럼을 조정하여 1회 사용분의 위사길이를 맞추어햐 하고, 항상 위사를 공급하기 위한 모우터가 가동상태에 있어야지만 하며, 저장파이프에서 위사가 형태로 꼬이지 않게 하기 위해 항상 저장파이프 내에 압축공기를 불어넣어야 하는 한편, 또한 압축공기가 위사를 U자형 파이프 속으로 정확하게 불어주지 못하면 주노즐이 경사의 개구사이로 원활하게 공급할수 없고 위사를 잡는 그리퍼에는 항상 위사가 지나가므로 먼지나 모우 등의 축적으로 인해 위사를 정확히 잡지 못하는 경우가 있었다.In order to solve the problem of the weft released from the bobbin, the weft released from the bobbin is loosely wound on the measuring drum, and the weft released from the bowel drum is used once without load on the U-shaped storage pipe by compressed air. There was a device that allowed the part to be stored so that the gripper was opened by the suction force of the main nozzle and the weft yarn which was not loaded on the U-shaped pipe was sprayed into the opening of the fabric. To adjust the weft length for one use, the motor must always be in operation to supply the weft, and the compressed air must always be blown into the storage pipe to prevent the weft from twisting. In addition, compressed air blows the weft into the U-shaped pipe precisely If you do not share the gripper nozzles can smoothly supplied through the opening of the slope without catching the weft yarn, the weft is therefore always gone some cases due to the accumulation of dust or fluffs can not exactly hold the weft.
이에 본고안에서는 상기의 제반문제점들을 해결하기 위하여 보빈으로부터 풀려나오는 위사가 모우터의 모우터축으로 통과되도록 하는 한편, 모우터축에는 위사를 안내해주는 안내부재를 설치하고 위사를 저장해 주는 위사저장드럼을 연장된 모우터축의 축심과 일치되도록 설치하고, 상기 위사저장드럼의 앞쪽에는 전자석으로 저장드럼에 접촉 또는 떨어지게 하는 그리퍼를 설치하므로써, 저장드럼에 감겨지는 위사가 공급또는 정지된다거나 꼬이는 현상없이 주노즐에 의해 경사개구 사이로 원활하게 공급될 수 있도록 한 에어젯트직기의 위사공급장치를 제공함에 그 목적이 있다.In this paper, in order to solve the above problems, the wefts released from the bobbin are passed through the motor shaft of the motor, while the weft thread is provided with a guide member for guiding the weft and the weft storage drum for storing the weft. It is installed so as to match the shaft center of the motor shaft, and a gripper for contacting or dropping the storage drum with an electromagnet in front of the weft storage drum is provided by the main nozzle without feeding or stopping or twisting the weft wound on the storage drum. It is an object of the present invention to provide a weft supply device for an air jet loom so as to be smoothly supplied between inclined openings.
이하 본 고안을 첨부된 도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본고안은 보빈(1)으로부터 풀려나오는 위사(2)를 모우터(3)의 모우터축(4)내부로 통과시켜서 상기 모우터(3) 옆쪽의 모우터축(4)에 설치되어 위사(2)를 안내해주는 안내부재(5)와 위사(2)를 저장하기 위한 저장드럼(6)및 위사(2)를 붙잡아주기 위한 그리퍼(7)를 통과하도록 하므로서 이 그리퍼(7)가 전자석(8)에 의해 저장드럼(6)에 접촉되거나 떨어지게 하므로서 위사의 공급을 제안하도록 한 구조로 되어 있다.The present invention passes the weft yarn (2) released from the bobbin (1) into the motor shaft (4) of the motor (3) and is installed on the motor shaft (4) next to the motor (3), the weft yarn (2) The gripper (7) passes through the storage drum (6) for storing the guide member (5) and the weft yarn (2) for guiding the gripper (7) and the gripper (7) for holding the weft yarn (2). By contacting or dropping the storage drum (6) by means of the structure to propose the supply of the weft.
상기의 구조로 이루어진 본 고안은 저장드럼(6)을 길이 방향으로 테이퍼지게 하여 저장드럼(6)에 감긴 위사(2)가 별 저항없이 잘 풀려지도록 하고, 또한 저장드럼(6)단부를 경사지게 하는 한편 상기 경사진 단부에 접촉하게 되는 그리퍼(7)의 내면을 경사지게 하여 그리퍼(7)가 저장드럼(6)에 긴밀하게 접촉되도록 하므로써 저장드럼(6)의 위사(2)가 주노즐(9)쪽으로 위입되지 않게하고 저장드럼(6)에는 위사(2)의 저장량을 감지하게 하는 감지기(10)를 설치하여 이 감지기로 저장드럼(6)의 위사(2)유무를 판단하여 저장드럼(6)에 위사량을 보충할 수 있게 한다.The present invention having the above structure allows the storage drum 6 to be tapered in the longitudinal direction so that the weft yarns 2 wound on the storage drum 6 are well unwound without resistance, and the storage drum 6 is inclined at an end thereof. On the other hand, the inclined inner surface of the gripper 7 which is in contact with the inclined end so that the gripper 7 is in intimate contact with the storage drum 6 so that the weft yarn 2 of the storage drum 6 is the main nozzle 9. The storage drum (6) is installed in the storage drum (6) so as to detect the storage amount of the weft yarn (2) by using the detector to determine the presence of the weft yarn (2) of the storage drum (6) storage drum (6) Allow to replenish the amount of weft
이하 본 고안의 작동상태를 설명하면 보빈(1)에 감긴 위사(2)가 모우터(3)의 작동에 따라 모우터축(4)으로 통과되게 하면서 모우터축(4)에 일체로 설치된 안내부재(5)를 따라 안내되어 저장드럼(6)에 장력이 주어지지 않고 너슨하게 감겨지게 된다.Referring to the operating state of the present invention will be described as a guide member integrally installed on the motor shaft (4) while allowing the weft yarn (2) wound on the bobbin (1) to pass through the motor shaft (4) in accordance with the operation of the motor (3) Guided along 5), the tension is not given to the storage drum (6) and is wound loosely.
저장드럼(6)에 감겨져 있는 위사(2)는 그리퍼(7)에 형성되어 있는 중심구멍을 통해 주노즐(9)에 안내되어 경사의 개구사이로 위입되게 된다. 이렇게 개구부사이로 위사의 위입이 완료되고 나면 위사감지 장치(도시안됨)에 의해 위사(2)의 주입 완료되었다는 신호가 전자석(8)에 전달되므로 전자석(8)은 즉시 그리퍼(7)를 저장드럼(6)의 단부에 긴밀하게 접촉되게 하여 위사(2)가 주노즐(9)로 공급되는 것을 정지시키게 된다.The weft yarn 2 wound around the storage drum 6 is guided to the main nozzle 9 through the center hole formed in the gripper 7 and entered into the inclined opening. When the weft of the weft is completed between the openings, a signal indicating that injection of the weft 2 is completed by the weft detecting device (not shown) is transmitted to the electromagnet 8, so that the electromagnet 8 immediately stores the gripper 7. In close contact with the end of 6), the weft yarn 2 is stopped from being supplied to the main nozzle 9.
위사저장드럼(6)의 측벽에 설치되어 있는 감지기(10)가 위사(2)없음의 신호를 보내면 저장드럼(6)은 모우터(3)가 회전되면서 위사(2)가 다시 저장드럼(6)에 보충되게하여 다시 다음동작인 주노즐(9)로서 경사의 개구사이로 위입되게 하는 순으로 계속 반복동작이 이루어지게 되므로 주노즐(9)로 위사의 공급이 이루어지기 전에 무장력상태를 유지시키기 용이하며, 종래와 같이 무장력상태를 유지시키고 꼬이지 않게하기 위하여 압축공기를 계속적으로 분사시킬 필요가 없고 또, 보빈으로부터 위사를 저장파이프에도 계속하여 공급하기 위하여 모우터를 계속하여 가동시켜야 하는 문제점이 해소되는 것이다.When the detector 10 mounted on the side wall of the weft storage drum 6 sends a signal without the weft yarn 2, the storage drum 6 rotates the motor 3 while the weft yarn 2 is again stored in the storage drum 6. ) To be replenished to the main nozzle (9), which is the next operation, to be inserted into the opening between the inclined openings, so that it is easy to maintain the tensioned state before the supply of the weft to the main nozzle (9). It is not necessary to continuously inject compressed air in order to maintain the tension-free state and to prevent twisting, and to solve the problem of continuously operating the motor in order to continuously supply the weft from the bobbin to the storage pipe. will be.
특히 본 고안은 위사(2)가 위사저장드럼(6)으로부터 풀려나오게 하면서 위사저장드럼(6)에 위사(2)가 다 소모되게 하였을 때에는 그리퍼(7)가 위사저장드럼(6)단부에 긴밀하게 접촉되면서 위사저장드럼(6)의 단부에 있는 위사(2)를 꼭잡아주게 되는데 이때 위사저장드럼(6)과 그리퍼(7)사이에는 먼지나 모우등의 이물질이 끼이지 않게되어 위사(2)를 항상 위사(2)를 정확하게 잡을 수 있고, 또한 위사(2)가 위사저장드럼(6)에 저장되어 있는 동안은 풀어지거나 꼬이지 않게되어 종래와 같이 저장파이프에 항상 압축공기를 불어넣을 필요가 없기 때문에 압축공기의 낭비가 없게 된다.In particular, the present invention, when the weft yarn (2) is released from the weft storage drum (6) while the weft yarn (2) is exhausted in the weft storage drum (6) when the gripper (7) close to the weft storage drum (6) end While holding the weft yarn (2) at the end of the weft storage drum (6) while being in contact with the weft storage drum (6) and the gripper (7) is not caught between the foreign matter such as dust or mousse weft yarn (2) ) Can always hold the weft (2) correctly, and also while the weft (2) is stored in the weft storage drum (6) does not loosen or twisted, it is necessary to always blow compressed air into the storage pipe as in the prior art There is no waste of compressed air.
이상의 설명에서와 같이 본 고안의 장치를 사용하므로서, 위사(2)가 저항없이 저장드럼(6)에 원활하게 감겨지게 되므로 경사개구사이로 위사공급이 용이하고 또 위사를 꼬임없이 무장력 상태로 공급하기 위한 부대설비를 필요로 하지 않게 되는 이점이 있다.By using the device of the present invention as described above, the weft yarn (2) is smoothly wound on the storage drum (6) without resistance, so that the weft supply is easy between the inclined opening and to supply the weft yarn in a tensionless state without twisting There is an advantage of not needing additional equipment.
