연결부재(10)의 결합부(13)가 축(15)에 축설된 부채꼴기어(16)에 연결핀(18)으로 결합되고, 상기 부채꼴기어(16)의 이빨과 치합되어 정, 역회전하는 구동기어(19)가 타측편(2')에 축설되도록 하는 축(20)에 휠(21)이 결합된 것에 있어서, 구동축(4)의 선단에 축설된 베벨기어(23)의 결합된 베벨기어(24)가 축설된 연동축(25)에 결합되어진 편심캠(26)과, 상기 편심캠(26)이 장착되고 볼베어링(27)이 장착되도록 요홈(28)이 형성된 안내홈(29)을 상기 연결부재(10)에 구성되는 레피어직기의 그레퍼헤드를 왕복 이동시키는 동력장치이다.The coupling part 13 of the connecting member 10 is coupled to the fan gear 16 arranged on the shaft 15 by a connecting pin 18, and is engaged with the teeth of the fan gear 16 to forward and reverse rotation. Combined bevel gears of bevel gears 23 arranged at the tip of drive shaft 4 in which wheel 21 is coupled to shaft 20 to allow drive gear 19 to be built up on the other side 2 '. An eccentric cam 26 coupled to an interlocking shaft 25 on which the 24 is constructed, and a guide groove 29 in which the recess 28 is formed so that the eccentric cam 26 is mounted and the ball bearing 27 is mounted. It is a power unit for reciprocating the graper head of the repier loom constituting the connecting member 10.

다른 실시예는 제4도에 도시된 것과 같이 편심캠(26)의 외주에는 볼베어링홈(30)이 형성된 돌부(31)를 형성하고, 상기 안내링(29)의 내주에는 다수개의 볼베어링홈(32)이 형성된 요홈(28)을 만들어 사용할 수도 있다.Another embodiment is formed in the outer circumference of the eccentric cam 26 as shown in Figure 4 formed a protrusion 31 formed with a ball bearing groove 30, a plurality of ball bearing grooves 32 on the inner circumference of the guide ring 29 ) Can be used to make grooves 28 formed.

이와 같이 편심캠(26)의 외주에는 볼베어링홈(30)이 형성된 돌부(31)를 연결부재(10)에 형성된 안내링(29)의 내주에는 다수개의 볼베어링홈(32)이 형성된 요홈(28)에 조립하되, 상기 볼베어링홈(30), (32)에는 볼베어링(27)을 안치시켜 편심캠(26)의 외주가 안내링(29)의 내주를 따라 회전할 시에 편심캠(26)의 외주와 마찰이 점 접점으로 되어 마찰을 줄일 수 있다.As described above, the groove 28 having the plurality of ball bearing grooves 32 formed on the inner circumference of the guide ring 29 formed on the connection member 10 includes the protrusion 31 having the ball bearing grooves 30 formed on the outer circumference of the eccentric cam 26. Although assembled in the ball bearing grooves 30 and 32, the ball bearing 27 is placed in the ball circumference of the eccentric cam 26 when the outer circumference of the eccentric cam 26 rotates along the inner circumference of the guide ring 29. And friction become point contact, which reduces friction.

이하 작용에 대하여 설명하면 다음과 같다.Hereinafter, the operation will be described.

직기의 본체에서 동력을 구동축(1)의 일단에 축설된 베벨기어(23)와 치합되어 회전하는 베벨기어(24)에 의하여 회전하는 연동축(25)에 축설된 편심캠(26)을 연결부재(10)의 일단에 형성된 안내링(29)의 내주에 결합시킨다.The connecting member connects the eccentric cam 26 arranged on the interlocking shaft 25 which is rotated by the bevel gear 24 which is rotated by being engaged with the bevel gear 23 arranged on one end of the driving shaft 1 in the main body of the loom. It is coupled to the inner circumference of the guide ring 29 formed at one end of (10).

이와 같이 상기 연동축(25)의 회전으로 편심캠(26)이 회전되는데 이때, 상기 편심캠(26)은 안내링(29)에 조립되어 있으므로 연결부재(10)의 일단에 형성된 안내링(29)의 내주를 따라 편심캠(26)이 회동하게 된다.In this way, the eccentric cam 26 is rotated by the rotation of the interlocking shaft 25. At this time, since the eccentric cam 26 is assembled to the guide ring 29, the guide ring 29 formed at one end of the connecting member 10. Along the inner circumference of the eccentric cam 26 is rotated.

따라서, 상기 연동축(25)의 회전에 의하여 안내링(29)과 일체로 된 연결부재(10)는 일정한 행정거리를 두고 왕복운동을 하고, 상기 연결부재(10)의 일단은 부채꼴기어(16)를 유동시켜 주기 때문에 상기 부채꼴기어(16)의 이빨과 치합된 구동기어(19)를 정, 역회전시켜준다.Therefore, the connecting member 10 integrally formed with the guide ring 29 by the rotation of the interlocking shaft 25 is reciprocated at a predetermined stroke distance, one end of the connecting member 10 is a fan gear 16 ), The drive gear 19 engaged with the teeth of the fan-shaped gear 16 is rotated forward and reverse.

그리고, 상기 구동기어(19)의 정, 역회전으로 휠(21)이 정, 역회전되도록 하여 그 구동기어(19)에 조립된 그리퍼헤드를 왕복 운동시켜 위사를 경사에 공급하는 것이다.Then, the wheel 21 is rotated forward and reverse by forward and reverse rotation of the drive gear 19, and the gripper head assembled to the drive gear 19 is reciprocated to supply the weft to the warp yarn.

이와 같이 구성된 본 발명은 부품의 개수를 줄여서 부품의 비용을 감소시켰을 뿐만 아니라 구조를 간단히 하여 고장의 원인을 줄여서 부품의 교환시간과 인건비의 소요를 줄일 수 있어 직기의 가동효과를 증가시킬 수 있다.The present invention configured as described above can reduce the cost of parts by reducing the number of parts as well as simplify the structure to reduce the cause of failure to reduce the replacement time and labor costs of parts can increase the operation effect of the loom.

이상과 같이 구동축의 회전력을 왕복운동으로 전환함에 있어 캠을 사용치 않으면서 소형화하고 회전력을 유연하게 왕복운동으로 전환시킬 수 있을 뿐만 아니라 구동축 동력을 직접 부채꼴기어에 전달함으로 적은 힘으로도 동력을 전달가능하고, 고속회전에도 회전운동을 무리하지 않게 왕복운동으로 변환시킬 수 있는 효과가 있다.As mentioned above, in converting the rotational force of the drive shaft into a reciprocating motion, it can be miniaturized without using a cam, and the rotational force can be flexibly converted into the reciprocating motion, and the drive shaft power is directly transmitted to the fan gear to transmit power with a small force. Possible, there is an effect that can be converted into a reciprocating motion without excessive force even in high-speed rotation.
