본 고안은 2열 프린트휠의 상하 구동장치에 관한 것으로, 휠 구동모우터에 축설된 프린트휠의 지지대에 설치시킨 베어링에 캠이 구동모우터에 연동되어 좌우 슬라이드 되게 설치하여 휠 구동모우터를 상하 이동시켜 인자하고자 하는 프린트 휠의 내외측열을 선택하여 한글, 영문, 숫자, 부호 등을 정확하게 인자토록 한 것이다. 종래의 프린트휠의 상하 구동장치는 스프링력에 의해 연동되게 하므로 휠 구동모우터의 상하 위치 정지 시간이 길어 타이핑 시간이 길어지었던 것이고, 휠구동 모우터가 축설된 작동구를 힌지축을 중심으로 구동시키므로 작동 전달의 구동 오차로 인하여 프린트 휠의 내측열로 인자시 프린터휠의 선택오차가 발생하며 기계적 모멘트가 작용하여 신속하고 정확한 구동이 결여 되었던 것이다.The present invention relates to a vertical drive device of a two-row print wheel, and the cam is interlocked with the drive motor to the bearing installed on the support of the print wheel installed in the wheel drive motor so that the wheel drive motor can slide left and right. By selecting the inner and outer columns of the print wheel to be printed by moving, it prints Korean, English, numbers, and symbols accurately. Since the vertical driving device of the conventional print wheel is linked by the spring force, the up and down position stop time of the wheel driving motor is long, so that the typing time is long, and the wheel driving motor drives the operating tool built around the hinge axis. Due to the driving error of the operation transmission, selection error of the printer wheel occurs when printing to the inner row of the print wheel, and the mechanical moment is applied to it, thereby causing a lack of fast and accurate driving.
본 고안은 상기 결점을 해결하기 위하여 캠을 좌우 슬라이드 되게 구동 모우터와 연동되는 연동기어와 캠 이면에 설치시킨 잭과 맞물리게 하여 프린트휠의 휠 구동 모우터저면에 설치시킨 로울러가 캠홈내에 슬립되게 하여서 프린트휠을 상하 구동시키므로 캠의 좌우 직선운동을 바로 상하직선운동으로 바꾸어캠의 높이차에 의해 직접적으로 인자상태에 영향을 주므로 인자된 글자체의 품질 향상과 타이핑 속도를 증가시키게 하였다.In order to solve the above drawbacks, the cam is engaged with the interlocking gear interlocked with the driving motor to slide the cam left and right, and the roller installed at the bottom of the wheel driving motor of the print wheel slips in the cam groove. Since the print wheel is driven up and down, the cam's right and left linear movements are changed directly to up and down linear movements, which directly affects the printing state by the height difference of the cam, thereby increasing the quality of the printed font and increasing the typing speed.
이를 첨부도면에 의하여 설명하면 다음과 같다. 브라켓트(1)에 고정시킨 캠측(2)(2')에 캠홈(3)이 형성된 캠(4)을 슬라이드 되게 설치 하였으며, 캠(4) 이면에 형성시킨 잭(5)이 구동모우터(6)의 주동기어(7)와 연동되는 연동기어(8)를 맞물게 설치하였다. 그리고 프린트휠(9)이 축설된 휠구동 모우터(10)전면에 부착된 지지대(11)의 하단에 베어링(12)을 유설하여 베어링(12)이 캠홈(3)에 삽입시켜 프린트 휠(9)이 캠(4)에 따라 승강되게 설치하였으며, 휠 구동 모우터(10)후면에 부착된 볼가이드(13)와 좌우측 가이드(14)(14')사이에 볼(15)을 개입시켜 휠구동 모우터(10)가 상하슬립이 용이하게 설치 하였고, 또한 휠구동 모우터(10)는 상방향으로 인장되는 스프링(16)(16')으로 볼가이드(13)연결편(17)에 탄설되게 설치한 것으로 미설명 부호 18는 플래턴이고, 19는 햄머이다.This will be described with reference to the accompanying drawings. The cam 4 having the cam groove 3 formed thereon is slidably mounted on the cam side 2 and 2 'fixed to the bracket 1, and the jack 5 formed on the rear surface of the cam 4 has a driving motor 6 ) Interlocking gear (8) interlocked with the main gear (7) of Then, the bearing 12 is placed at the lower end of the support 11 attached to the front surface of the wheel driving motor 10 in which the print wheel 9 is built up, and the bearing 12 is inserted into the cam groove 3 to print the wheel 9. ) Is installed to move up and down along the cam (4), the wheel drive through the ball 15 between the ball guide 13 and the left and right guides (14, 14 ') attached to the rear of the wheel drive motor (10) The motor 10 is easily installed on the upper and lower slips, and the wheel drive motor 10 is installed in the ball guide 13 and the connecting piece 17 by springs 16 and 16 'which are tensioned in the upward direction. The reference numeral 18 is a platen, and 19 is a hammer.
이와 같이된 본 고안의 작용효과를 상술하면, 구동 모우터(6)가 구동하게 되면 주동기어(7)에 연동된 연동 기어(8)가 회동됨에 따라 연동기어(8)에 맞물려 있는 캠(4)의 잭(5)을 이동시켜 캠(4)이 캠축(2)(2')에서 좌우 이동시켜서 프린트휠(9)의 내측열을 인자하고자 할경우에 캠(4)을 좌측으로 이동시키게 되면 휠구동모우터(10)저면 지지대(11)하단에 설치된 베어링(12)이 캠홈(3)에 삽입된채 부드럽게 구동되어 도면 제3도와 같은 상태가 되여서 프린트휠(9)이 축설된 휠구동 모우터(10)을 상방향으로 이동시키게 되어 프린트휠(9)의 내측열을 햄머(19)로 플래턴(18)에 인자시킬 수 있는 것이다.When the driving effect of the present invention is described in detail, the cam 4 engaged with the interlocking gear 8 as the interlocking gear 8 linked to the main gear 7 is rotated when the driving motor 6 is driven. When the cam 4 is moved left and right on the camshaft 2, 2 'by moving the jack 5 of the cam, the cam 4 is moved to the left to print the inner row of the print wheel 9. Wheel drive motor 10 The bearing 12 installed at the bottom of the bottom support 11 is driven smoothly while being inserted into the cam groove 3 to be in the state as shown in FIG. 3, so that the wheel drive mower with the print wheel 9 built up. The rotor 10 is moved upward so that the inner row of the print wheel 9 can be printed onto the platen 18 by the hammer 19.
이때 휠구동 모우터(10)의 이동에 있어서, 휠구동모우터(10)후면에 부착된 볼가이드(13)와 좌우측 가이드(14)(14')사이에 개입된 볼(15)에 의해 휠구동모우터(10)의 이동을 부드럽게하며, 볼가이드(13)의 연결편(17)에 인장스프링(16)(16')으로 연결되어 있어 승강을 정확하고 신속하게 하면서 기계적인 무리를 더욱 감소시킬수 있는 것이다. 그리고 프린트휠(9)의 외측열을 인자하고 가할때에는 역으로 구동모우터(6)에 연동되는 연동기어(8)의 역회전으로 잭(5)의 이동을 도면 제3도의 상태에서 우측으로 이동시 휠구동 모우터(10)을 하강시켜서 프린트휠(9)의 외측열을 햄머(19)로 인자시킬 수 있는 위치에 위치시킬 수 있는 것이다.At this time, in the movement of the wheel driving motor 10, the wheel by the ball 15 interposed between the ball guide 13 attached to the rear of the wheel driving motor 10 and the left and right guides 14, 14 '. It smoothly moves the driving motor 10 and is connected to the connecting piece 17 of the ball guide 13 by the tension springs 16 and 16 ', so that the mechanical force can be further reduced while the lifting and lowering is accurate and quick. It is. When the outer row of the print wheel 9 is printed and applied, the jack 5 is moved to the right in the state shown in FIG. 3 by reverse rotation of the interlocking gear 8 interlocked with the driving motor 6. The wheel drive motor 10 can be lowered so that the outer row of the print wheel 9 can be positioned at a position that can be printed by the hammer 19.
이와같이 본 고안은 캠(3)의 좌우 슬라이딩으로 휠구동 모우터(10)의 베어링(13)이 밀리면서 휠구동 모우터(10)의 볼가이드(13)와 좌우측 가이드(14)(14') 내에서 볼(15)이 슬립되어 휠구동 모우터(10)를 상하 승강구동시켜 충격 및 오차 발생이 거의 없이 작동구의 안정 시간이 필요치 않고 스프링(16)(16')으로 프린트 휠구동 모우터(10)의 자중을 감쇠시키어 적은 힘으로 빠른 시간내에 구동시킬 수 있는 것이다.As described above, the present invention pushes the bearing 13 of the wheel drive motor 10 by the left and right sliding of the cam 3 and the ball guide 13 and the left and right guides 14 and 14 'of the wheel drive motor 10. The ball 15 slips in and lifts the wheel drive motor 10 up and down, so that there is little shock and error, so that the stability time of the operation port is not necessary, and the spring wheel 16 (16 ') print wheel drive motor ( It can attenuate the self-weight of 10) and drive it in a short time with low force.
