Description

레피어 직기용 구동장치{A DRIVING GEAR DEVICE FOR REP-WEAVING MACHINE}Drive device for the piercing loom {A DRIVING GEAR DEVICE FOR REP-WEAVING MACHINE}

본 발명은 레피어 직기용 구동장치에 관한 것으로서,The present invention relates to a drive device for a repier loom,

더욱 상세하게는 레피어 직기의 경사에 위사를 인입시키기 위하여 일단에 헤드를 부착한 레피어 밴드를 왕복운동시키기 위한 그리퍼의 회전운동을 왕복운동으로 변환시키는 구동장치에 관한 것이다.More particularly, the present invention relates to a driving device for converting a rotational motion of a gripper to reciprocate a reciprocating motion of a piercing band attached to a head in order to introduce a weft yarn to an inclination of a piercing loom.

일반적으로 레피어직기의 구동장치는 직기의 동력을 전달받은 그리퍼의 정.역회전으로 레피어밴드를 왕복운동시켜 레피어직기의 경사에 위사를 인입시킴으로서 직물을 제직하는 것이다. 상기한 바의 구동장치에서 레피어 밴드가 바뒤침하기위해서는 그리퍼는 정.역회전을 하면서 회전운동이 왕복운동으로 변환되어야 하는 바,In general, the driving device of the repier weaving machine is to weave the fabric by drawing the weft on the inclination of the repier loom by reciprocating the repetitive band by the forward and reverse rotation of the gripper which receives the power of the loom. In order to revert the rapier band in the driving device of the bar as described above, the gripper should be converted into a reciprocating motion while the gripper performs forward and reverse rotation.

상기, 정.역회전의 회전운동을 왕복운동으로 변환시키는 과정에서도 직기의 동력은 그리퍼에 계속 전달되어지게 되고 이때 그리퍼의 회전을 순간차단하기 위한 여러종류의 구동장치가 개발된 바 있으며, 이러한 종래의 구동장치 중에서도 널리 알려져 있는 벨기에의 피카놀사에서 제작한 4점 링크방식의 구동장치(일명 피카놀형이라고 함)는 내부에 헬리컬기어를 설치하여 헬리컬기어와 치합되는 구동캠과 별도의 복귀 구동캠을 이용하여 부채꼴 형태의 기어를 왕복운동시켜 기어의 왕복운동으로 그리퍼를 정.역 회전시켜 레피어 밴드를 왕복운동시키는 구조로 이루어져 있다.In the process of converting the rotational motion of the forward and reverse rotation into the reciprocating motion, the power of the loom continues to be transmitted to the gripper, and at this time, several types of driving devices have been developed to momentarily block the rotation of the gripper. The four-point link type drive device (also known as the Picanol type) manufactured by Pikano Co. of Belgium, which is widely known among the drive devices of Belgium, installs a helical gear inside and separates the drive cam from the helical gear and a separate return drive cam. The reciprocating motion of the fan-shaped gear is used to rotate the gripper forward and backward by the reciprocating motion of the gear.

그러나 상기한 구조는 구동축의 구동력이 기어에 전달되면서 회전운동으로 정확히 변환될 수는 있으나 헬리컬기어를 통해 부채꼴 형태의 기어를 작동케 하므로 헬리컬기어의 마모에 의한누적 공차가 증가하게 되며, 헬리컬기어와 치합되는 구동캠과 복귀 구동캠간의 약간의 오차 발생에도 순차적으로 작동하므로 헬리컬기어가 무리한 힘을 받게 되어 파손율이 높은 폐단이 있었고 또한 상기한 구조는 부피가 크고 그 구조가 매우 복잡하여 기존 레피어직기에 설치시 많은 제약이 따랐으며, 레피어 밴드의 전기장이 길어지게 되어 이로 인해 마찰이 심해질 뿐 아니라 밴드의 파손율이 높게 되고, 특히 경제성이 저하되는 등의 여러가지 문제가 따르는것이었다.However, the above structure can be accurately converted to rotational movement as the driving force of the drive shaft is transmitted to the gear, but because the helical gear operates the gear of the fan-shaped gear, the accumulated tolerance due to the wear of the helical gear is increased. The helical gear is subjected to unreasonable force because it operates sequentially even when a slight error occurs between the driving cam and the return driving cam to be engaged, and there is a high breakage ratio. Many restrictions were placed on the installation of the loom, and the electric field of the rapier band became long, which caused a lot of problems such as not only severe friction but also high breakage rate of the band, and particularly economical efficiency.

본 발명은 상기한 바의 문제점을 해결하기 위하여 노력 연구한 결과, 상기 종래기술의 캠 대신에 회전부재와 연결부재를 이용하여 부채꼴기어를 일정 스트로크 회동시킴으로써 구동기어를 구동시키면서 바뒤침하는 동안에 부채꼴기어의 회동을 막아 그리퍼의 회전을 순간 차단함과 동시에 소형화 된 간단한 구조로 레피어직기의 단가를 절감시킬 수 있을 뿐 아니라 기존 레피어직기에도 적용 가능하여 경제성을 향상 시킴을 그 목적으로 한다.The present invention has been conducted to solve the above problems, and as a result, instead of the cam of the prior art by using a rotating member and the connecting member by rotating the fan gear by a constant stroke, while driving the drive gear while flat gears while spinning Its purpose is to improve the economical efficiency by not only reducing the rotation of the gripper but also reducing the unit cost of the repier weaving machine by reducing the unit cost.

위와 같이 구성된 본 발명은 감속클러치(2)의 풀리(4)와 벨트(7)로 연결된 구동축(5)의 풀리(6)가 구동모터(1)의 동력을 전달받게 되면 구동축(5)이 구동되면서 구동축(5)의 타단부에 축설된 회전부재(8)를 회전시키게 되고 이에 따라 회전부재(8)와 지지축핀(10)으로 연결된 연결부재(9)가 왕복운동하게 되는 바,According to the present invention configured as described above, when the pulley 6 of the drive shaft 5 connected to the pulley 4 and the belt 7 of the reduction clutch 2 receives the power of the drive motor 1, the drive shaft 5 is driven. While rotating the rotating member 8 arranged on the other end of the drive shaft (5) and thus the connecting member 9 connected to the rotating member 8 and the support shaft pin 10 is reciprocating bar,

상기, 연결부재(9)의 왕복운동에 따라 연결부재(9)와 편심지게 연결된 부채꼴기어(11)가 중심축(16)을 기점으로 왕복회동하면서 부채꼴기어(11)에 치합된 구동기어(14)를 정.역 회전시키게 되고, 구동기어(14)의 정.역회전 동작이 스파이럴 베벨기어(20)를 통해 그리퍼(18)에 전달되면서 그리퍼(18)의 회전으로 레피어밴드(19)를 왕복운동으로 변환시키면서 직기의 경사에 위사를 일입시키게 되는 바,According to the reciprocating motion of the connecting member 9, the fan gear 11 eccentrically connected with the connecting member 9 is engaged with the fan gear 11 while being reciprocated from the central axis 16 as a starting point. ) And forward / reverse rotation of the drive gear 14 is transmitted to the gripper 18 through the spiral bevel gear 20 to rotate the gripper 18 by rotating the gripper 18. While converting the reciprocating motion to the weft inclined loom bar,

이때, 구동축(5)의 구동으로 그리퍼(18)를 정.역회전시켜 직기에 위사를 공급하는 레피어 직기는 위사를 공급하고 나서 바뒤침으로 직물을 제직하기 위하여서는 바뒤침하는 시간동안에는 그리퍼(18)의 회전을 순간 차단시켜야 할 필요가 있다.At this time, the rapier loom that supplies the weft yarn to the loom by rotating the gripper 18 forward and reverse by driving the drive shaft 5 is supplied with the weft yarn and then gripper (during the weaving time to weave the fabric with the back stitch). It is necessary to cut off the rotation of 18) momentarily.

따라서 그리퍼(18)의 회전을 순간 차단하기 위하여서는 구동축(5)의 계속되는 구동으로도 부채꼴기어(11)가 중심축(16)을 기점으로 회동되지 않게 하거나 회동되어도 아주 미세하게 회동되어 그리퍼(18)의 회전을 순간 차단시켜 바뒤침하는 동안에는 레피어밴드(19)의 이동을 막아 일정시간동안 정지되는 것과 같은 작용을 하게 되는 것이다.Therefore, in order to interrupt the rotation of the gripper 18 at a moment, even when the driving shaft 5 continues to drive, the fan gear 11 is not rotated about the central axis 16 or rotated very finely even when the gripper 18 is rotated. During the moment of blocking the rotation of the instantaneous rotation) to prevent the movement of the rapier band 19 is to act like a stop for a certain time.

이상과 같은 본 발명은 구동축의 구동에 의한 그리퍼의 회전운동을 왕복운동으로 변환시킴에 있어 종래와 같이 캠을 사용치 않으면서 소형화하고 회전운동을 유연하게 왕복운동으로 변화시키게 되므로 부채꼴기어의 중심축과 일정 거리를 두고 설치되는 연결부재의 왕복동 힘을 부채꼴기어 전체에 고르게 분산시키게 되어 부채꼴기어를 안전하고 오랫동안 사용할 수 있으며 회전운동을 왕복운동으로 정확히 변환시킬 뿐 아니라, 베어링의 마모시 베어링만 교체시키면 되므로 누적 공차가 발생하지 않으면서 제작단가를 줄일수 있고, 고속 회전이나 큰 동력에도 회전운동을 무리하지 않게 왕복운동으로 변환시키므로 직기의 내구성을 증대시킬수 있으며 구동축의 구동시에도 그리퍼가 회전되지 않아 바뒤침하는 동안의 일정시간 밴드의 헤드가 이동되지 않고 정지되는 등의 효과가 있는 등 본 발명에 의하여 달성되는 효과가 매우 큰 것이다.As described above, the present invention converts the gripper's rotational motion by driving the drive shaft into a reciprocating motion. Therefore, it is miniaturized without using a cam as in the prior art and the rotational motion is flexibly changed to the reciprocating motion. It distributes the reciprocating force of the connecting member installed at a certain distance evenly throughout the fan gear, so that the fan gear can be used safely and for a long time. Therefore, the manufacturing cost can be reduced without accumulating tolerance, and the rotational movement can be converted into a reciprocating movement without excessive force even at high speed or large power, which can increase the durability of the loom and the gripper does not rotate even when the driving shaft is driven. The head of the band moves for a while during the sinking The effect attained by the present invention such that is effective, such as to be stopped without would be very large.
