본 고안은 자동횡편기의 캐리지구동장치에 관한 것으로 보다 구체적으로는 캐리지를 왕복운동시켜주는 전동식 구동장치를 개량한 것이다.The present invention relates to a carriage driving device of an automatic flat knitting machine, and more specifically, to an electric drive device for reciprocating a carriage.

종래의 전동식 구동장치는 구동수단이 서보모터로 이루어져 있고, 전동수단이 모터의 회전운동을 직선운동으로 변환시켜주는 여러 형태의 편심운동기구 및 스프로켓휘일과 드라이브체인 또는 벨트풀리와 드라이벨트로 이루어진 것으로서 서보모터의 경우 회전방향의 반전 특성이 우수한 반면에 국산품이 없어 수입품에 의존했었고, 또 비교적 고가이기 때문에 편기 전체의 제작비용 상승을 초래했었을 뿐 아니라 전동수단에 있어서도 운전속도가 낮고 동력손실이 큰 편심운동기구를 사용하고 스프로켓휘일, 드라이브체인의 경우 전동 효율이 높은 반면에 소음이 크게 발생되는 반면에 전동효율이 낮고 장시간 사용시 슬립이 일어나 캐리지를 정확하게 왕복운동시켜 줄 수 없게 되는 등의 문제점이 있었다.In the conventional electric drive device, the driving means is composed of a servo motor, and the electric means is composed of various types of eccentric motion mechanisms, sprocket wheels, drive chains, belt pulleys and dry belts that convert the rotational motion of the motor into linear motion. In the case of servo motor, the reversal direction of rotation was excellent, but there was no domestic product, so it was dependent on imported goods, and because it was relatively expensive, it resulted in an increase in the manufacturing cost of the whole knitting machine. In case of using eccentric exercise mechanism and sprocket wheel and drive chain, the motor efficiency is high while noise is generated. On the other hand, the motor efficiency is low and slip occurs during long time, which makes it impossible to precisely reciprocate the carriage. .

본 고안자는 상술한 바와 같은 종래의 제반문제점을 예의 검토한 결과 구동수단을 국내에서 저렴한 비용으로 구득이 용이한 3상유도전동모터로 대체할 경우 서보모터에 비해 회전방향의 반전특성이 다소 낮지만 캐리지를 비교적 정확하게 왕복운동시켜줄 수 있으며, 구동수단과 캐리지를 연결하는 전동수단을 타이밍벨트풀리와 타이밍벨트로 대체할 경우 회전력을 정확하게 전달할 수 있고, 특히 캐리지의 운동거리를 수시로 편직무늬에 따라 가변하면서 왕복 운동시켜 주는데 매우 적합한 것임을 알게 되어 저렴한 비용으로 만들 수 있으며 높은 전동효율로 캐리지를 정확하게 왕복운동시켜줄 수 있음을 특징으로 하는 본 고안 캐리지구동장치를 완성하기에 이르렀다.The present inventors have studied the conventional problems as described above. As a result, when the driving means is replaced with a three-phase induction motor that can be easily obtained at low cost in Korea, the reversal characteristic of the rotational direction is slightly lower than that of the servo motor. The carriage can be reciprocated relatively accurately, and when the transmission means connecting the drive means and the carriage is replaced by the timing belt pulley and the timing belt, the rotational force can be transmitted accurately. In particular, the movement distance of the carriage is often changed according to the knitting pattern. It was found that it is very suitable for the reciprocating motion can be made at a low cost and to complete the carriage drive device of the present invention, characterized in that the carriage can be accurately reciprocated with high transmission efficiency.

(18) And it consists of a vertical connection portion 19 that forms these horizontal portions 17, 18 in a single frame.

상기 메인프레임(10)의 한쪽 수직프레임(11)에는 캐리지구동용 3상유도전동모터(20)가 세워진 상태로 고정되어 있고, 모터축(21)에는 구동타이밍벨트풀리(22)가 끼워져 있다.One vertical frame 11 of the main frame 10 is fixed with a carriage driving three-phase induction motor 20 upright, and a drive timing belt pulley 22 is fitted to the motor shaft 21.

전동수단 지지프레임(14)(14')의 상, 하측 수평부(18), (19)사이에 회전자재토록 끼워진 회전축(23)(23')에는 타이밍벨트풀리(24), (24')가 끼워져 있고, 이 풀리(24), (24')에는 타이밍벨트(25)가 걸려져 있으며, 이 타이밍벨트(25)와 캐리지(C)는 제2도 및 제3도에 상세히 표현된 바와같이 연결구(26)로 함께 운동할 수 있도록 연결되어 있다.Timing belt pulleys 24, 24 'on rotating shafts 23, 23' sandwiched between the upper and lower horizontal portions 18, 19 of the drive means supporting frames 14, 14 '. And the timing belt 25 is fastened to the pulleys 24 and 24 ', and the timing belt 25 and the carriage C are as shown in detail in FIGS. The connector 26 is connected to be able to exercise together.

이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

본 고안은 제1도 및 제2도에 작용효과를 설명하면 다음과 같다.The present invention describes the effects of the first and second in FIG.

본 고안은 제1도 및 제2도에 예시된 바와 같이 캐리지(C)를 전동식으로 구동시켜줌에 있어서, 메인프레임(10)의 한쪽 수직프레임(11)에 세워진 상태로 고정된 3상유도전동모터(20)에 전원을 공급하면서 정, 역방향으로 회전시키면 모터축(21)의 구동타이밍벨트풀리(22)와 구동타이밍벨트(28)에 의해 전동수단 지지프레임(14)의 감속타이밍벨트풀리(27)가 회전되고, 이 풀리(27)와 동일한 회전축(23)상에 고정된 타이밍벨트풀리(24)와 다른 전동수단 지지프레임(14')의 타이밍벨트풀리(24')사이를 연결하는 타이밍벨트(25)가 좌, 우로 반전운동을 하게 된다.According to the present invention, the three-phase induction motor is fixed in a standing state on one vertical frame 11 of the main frame 10 to electrically drive the carriage C as illustrated in FIGS. 1 and 2. When the motor is rotated in the forward and reverse directions while supplying power to the motor 20, the speed reduction timing belt pulley 27 of the transmission means support frame 14 is driven by the drive timing belt pulley 22 and the drive timing belt 28 of the motor shaft 21. Is rotated, and the timing belt is connected between the timing belt pulley 24 fixed on the same rotating shaft 23 as the pulley 27 and the timing belt pulley 24 'of the other transmission means support frame 14'. (25) will reverse the left and right.

따라서 이 타이밍벨트(25)와 연결구(26)로 연결되어 있으며, 메인프레임(10)의 양쪽 수직프레임(11), (11')위에 고정된 가이드바아 지지프레임(13), (13')에 양쪽 끝이 지지되는 가이드바아(12)에 활주가능하게 끼워진 캐리지(C)가 좌, 우로 왕복운동을 하는 것이다.Therefore, the timing belt 25 and the connector 26 are connected to the guide bar support frames 13 and 13 'fixed on both vertical frames 11 and 11' of the main frame 10. Carriage (C) slidably fitted to the guide bar (12) on which both ends are supported is to reciprocate left and right.

상술한 바와같은 본 고안은 캐리지(C)가 활주가능하게 끼워진 가이드바아(12)가 메인프레임(10)의 양쪽 수직프레임(11), (11')위에 고정된 가이드바아 지지프레임(13), (13')의 상향연장부(15)에 지지되어 있고, 캐리지(C)를 상기 양쪽 수직프레임(11), (11')위쪽 후방에 고정된 전동수단 지지프레임(14), (14')에 설치된 타이밍벨트(25)로 직접 운동시켜주는 것이기 때문에 구조적인 면에서 매우 안정감이 있을뿐 아니라 캐리지와 전동수단사이에 크로스가이드바아를 별도로 설치하고, 이크로스가이드바아상에 활주가능하게 끼워진 크로스가이드와 슬라이드피스 등으로 연결하였던 종래것에 비하여 구조가 간단하여 전동효율이 높고, 구동수단을 종래의 고가인 수입품 서보모터 대신에 회전방향의 반전특성이 다소 낮지만 저가이며 국내에서도 구득이용이한 3상유도전동모터(20)를 사용하고, 전동수단을 저소음으로 정확하게 회전력을 전달 할 수 있는 타이밍벨트(22), (28)로 단일화한 것이기 때문에 저렴한 비용으로 제작할 수 있고 높은 전동효율로 캐리지를 정확하게 운동시켜 줄 수 있는 장점이 있다.The present invention as described above, the guide bar support frame 13 is fixed to the guide bar 12, the carriage C is slidably fitted on both vertical frames 11, 11 'of the main frame 10, A transmission means supporting frame 14, 14 'supported by an upward extension 15 of 13' and fixed to the rear of the carriage C above the two vertical frames 11, 11 '. Because it is directly moved by the timing belt 25 installed in the structure, it is not only very stable in structure but also has a cross guide bar separately installed between the carriage and the transmission means, and the cross guide slidably fitted on the cross guide bar. Compared with the conventional one connected with a slide piece and a slide piece, the structure is simpler, and the transmission efficiency is higher. Instead of the conventionally expensive imported servo motor, the reversal characteristic of the rotation direction is rather low, but it is inexpensive and easily available in Korea. Judo Using the motor 20 and unifying the transmission means with timing belts 22 and 28 which can accurately transmit the rotational force with low noise, it can be manufactured at low cost and the carriage can be accurately moved with high transmission efficiency. There are advantages to give.
