본 고안은 브이 씨 알이나 디 에이 티의 릴을 구동함과 아울러 릴의 급제동을 수행하는 릴 구도 및 급 제동장치에 관한 것이다.The present invention relates to a reel composition and a rapid braking device for driving a reel of a V seed or a DI and performing a rapid braking of the reel.

종래 브이 씨 알이나 디 에이 티의 릴구동 및 급 제동장치는 제 1 도에 도시한 바와같이 캡스탄 모터(1)에 중립기어(5)를 캡스턴 풀리(2)와 중립풀리(3) 및 벨트(4)로 연장연결하고, 상기 중립기어(2)와 이에 맞물리는 중립 아이들러(6)를 중립렐버(7)에 지지하며, 공급릴(8)의 공급기어(9)와 권취릴(10)의 권취기어(11)에는 각각 공급 아이들러(12)와 권취아이들러(13)를 맞물리게 설치하고, 공급릴(8)과 권취릴(10)전방측에는 모드기어(14)의 캠홈(15)에 안내되는 모드레버(16)에 연동연결된 평션판(17)을 스프링(18)으로 탄지하며, 그 일측에는 내측경사면(19)을, 타측에는 외측경사면(20)을 형성하여 상기 공급릴(8)과 권취릴(10)에 접탈되는 급브레이크(21)(22)의 제동돌기(23)(24)를 연동되게 하고 양측 급브레이크(21)(22)는 서로 스프링(25)으로 연결한 것이었다.Conventional V-seed or D reel drive and rapid braking device, as shown in Figure 1, the capstan motor (1) with a neutral gear (5) capstan pulley (2), neutral pulley (3) and belt (4), the neutral gear (2) and the neutral idler (6) engaged with it support the neutral lever (7), the feed gear (9) and the reel (10) of the supply reel (8) In the winding gear 11 of the feeding idler 12 and the winding idler 13 are respectively installed to be engaged, the front of the feed reel 8 and the winding reel 10 is guided to the cam groove 15 of the mode gear 14. The flat plate 17 interlocked with the mode lever 16 is supported by the spring 18, and the inner side inclined surface 19 is formed at one side and the outer side inclined surface 20 is formed at the other side thereof. The brake protrusions 23 and 24 of the sudden brakes 21 and 22 attached to the reel 10 were interlocked, and both of the sudden brakes 21 and 22 were connected to each other by a spring 25.

이러한 종례장치에서는 상기 캡스탄 모터(1)가 시계방향으로 회전하면 중립레버(7)가 좌측으로 회동하여 중립아이들러(6)가 공급아이들러(12)와 맞물리면서 공급릴(8)측에 동력을 전달하며, 캡스탄 모터(1)가 반시계방향으로 회전하면 위와 역작용으로 권취릴(10)측에 동력을 전달하게 되는 것인 바, 이때 급제동(FF/REW시 급제동)을 하는 경우 모드기어(14)의 급제신호에 따라 모드레버(16)가 회동되면서 평션판(17)을 우측으로 이동시키게 되고 이에따라 제동돌기(23)(24)가 내, 외측 경사면(19)(20)을 타고 하방으로 이동되어 양측 급브레이크(21)(22)는 공급릴(8)이 권취릴(10)을 제동하게 되는 것이다.In this example device, when the capstan motor 1 rotates in the clockwise direction, the neutral lever 7 rotates to the left side so that the neutral idler 6 engages with the feed idler 12 and transmits power to the supply reel 8 side. When the capstan motor 1 rotates counterclockwise, power is transmitted to the take-up reel 10 in the opposite direction as above. In this case, when the braking is performed (quick braking at FF / REW), the mode gear 14 As the mode lever 16 is rotated according to the feeding signal of), the motion plate 17 is moved to the right. Accordingly, the brake protrusions 23 and 24 move downwards on the inner and outer inclined surfaces 19 and 20. Thus, both side brakes 21 and 22 may cause the supply reel 8 to brake the take-up reel 10.

그러나 종래장치에서는 상술한 급제동시에도 중립 아이들러(6)가 공급 아이들러(12) 또는 권취 아이들러(13)에 맞물린 상태에서 이탈(중립으로 복귀)되지 않게 때문에 캡스탄 모터(1)에 전원이 차단된 후에도 그 관성력에 의한 회전력이 계속 공급릴(8) 또는 권취릴(10)에 전달되는 것이어서 제동시간의 지연과 테이프의 장력 증가로 인한 극단적인 경우 테이프의 절단을 초래하고, 제품의 수명을 단축시키게 되는 폐단이 있었다.However, in the conventional apparatus, the power supply to the capstan motor 1 is cut off because the neutral idler 6 is not detached (returned to neutral) while being engaged with the supply idler 12 or the winding idler 13 even during the sudden braking described above. Afterwards, the rotational force due to the inertia force is continuously transmitted to the supply reel 8 or the take-up reel 10, resulting in cutting of the tape in extreme cases due to a delay in braking time and an increase in the tension of the tape, and shortening the life of the product. There was a discontinuance.

따라서 본 고안은 이러한 종래의 폐단을 해소하기 위하여 공급릴이나 권취릴의 급제동시 중립 아이들러가 중립위치로 복귀되어 캡스탄 모터의 관성력에 의한 회전력이 공급릴이나 권취릴측에 전달되지 않도록 함으로써 제동시간이 단축되어 급제동이 원할하게 되며, 테이프의 손상방지 및 수명연장과 제품의 신뢰성 향상을 기할 수 있도록 한 릴 구동 및 급제동장치를 제공하려는 것으로, 이를 첨부 도면에 따라서 상세히 설명한다.Therefore, the present invention provides a braking time by preventing the neutral idler from returning to the neutral position when the braking of the supply reel or the take-up reel in order to solve the conventional closed end, so that the rotational force by the inertial force of the capstan motor is not transmitted to the supply reel or the reel side. Short braking is reduced, and it is desirable to provide a reel driving and braking device capable of preventing damage to the tape, extending the life, and improving the reliability of the product, which will be described in detail with reference to the accompanying drawings.

Brake protrusions 23 and 24 of the rapid brakes 21 and 22 which are formed by the springs 25 by forming the inner inclined surface 19 and the outer inclined surface 20 on both sides of the flat plate 17 which are supported by each other. In linking, the neutral lever 7 extends the neutral return linkage projections 26 to the side of the flat plate 17, and linkage projections 29 and 30 linked to both sides of the linkage projections 26. A pair of neutral return type cams (27) and (28) which hold a) is supported on the main base and connected to each other by interlocking teeth (31) and (32), and to one side of the neutral return cam (27).

미설명 부호 2는 캡스탄 풀리, 3은 중립풀리, 4는 벨트, 12는 공급아이들러, 13은 권취아이들러, 15는 캠홈이고, 42는 제어회로부이다.Reference numeral 2 is a capstan pulley, 3 is a neutral pulley, 4 is a belt, 12 is a supply idler, 13 is a winding idler, 15 is a cam groove, and 42 is a control circuit part.

이와같이 구성된 본 고안의 릴 구동 및 급제동장치는, 상기 캡스탄 모터(1)가 시계방향으로 회전하면 중립레버(7)가 좌측으로 회동하여 중립 아이들러(6)가 공급 아이들러(12)와 맞물리면서 공급릴(8)측에 동력을 전달하며, 캡스탄 모터(1)가 반시계 방향으로 회전하면 위와 역작용으로 권취릴(10)측에 동력을 전달하게 되는 것인 바, 이때 급제동(F/REW시 급제동)을 하는 경우 모드기어(14)의 급제동신호에 따라 모드레버(16)가 회동 되면서 평션판(17)을 우측으로 이동시키게 되고 이에따라 제동돌기(23)(24)가 내, 외측 경사면(19)(20)을 타고 하방으로 이동되어 양측급브레이크(21)(22) 공급릴(8)과 권취릴(10)을 제동하게 되는 것이다.The reel driving and braking device according to the present invention configured as described above includes a supply lever while the neutral lever 7 rotates to the left side when the capstan motor 1 rotates clockwise, so that the neutral idler 6 engages with the supply idler 12. The power is transmitted to the (8) side, and when the capstan motor (1) rotates in the counterclockwise direction, the power is transmitted to the winding reel (10) side in the opposite direction to the above. In this case, sudden braking (quick braking during F / REW) In this case, the mode lever 16 is rotated according to the sudden braking signal of the mode gear 14 to move the flat plate 17 to the right. Accordingly, the brake protrusions 23 and 24 are inward and outward inclined surfaces 19. (20) is moved downwards to brake both side brakes (21) and (22) feed reel (8) and take-up reel (10).

여기서 상기 중립 아이들러(6)가 공급 아이들러(12) 또는 권취 아이들러(13)에 맞물린 상태에서는 제 4a 도와 같이 중립레버(7)의 중립복귀용 연동돌기(26)이 중립 복귀용 캠(27) 또는 (28)의 연동돌기(29) 또는 (30)을 밀게 되며 이에 따라 양측 캠(27)(28)은 연동치부(31)(32)에 의해 동시에 회동되며, 이때 일측 캠(27)의 캠돌기(33)가 평션판(17)의 캠연동돌기(34)에 접힌 상태로 되는 바, 이 상태에서 급제동신호가 전달되면 평션판(17)이 우측으로 이동되게 되는데 이때 정지돌기(5)와 정지핀(38)으로 정지되었던 평션판(17)이 제어회로부(42)의 지령에 따른 솔레노이드(41)의 동작으로 정지레버(37)를 회동시키는 것에 의해 해제되어 평션판(17)은 스프링(18)에 의해 신속히 우측으로 이동되면서 캠연동돌기(34)가 일측 캠(27)의 캠돌기(33)를 밀게 되어 캠(27)(28)이 중앙을 향해 회동되면서 중립레버(7)를 중립위치(제 4b 도 상태)로 복귀시키게 된다.Here, in the state where the neutral idler 6 is engaged with the supply idler 12 or the winding idler 13, the neutral return linkage 26 of the neutral lever 7 is the neutral return cam 27 or the fourth lever. The interlocking protrusions 29 or 30 of the 28 are pushed so that both cams 27 and 28 are rotated at the same time by the interlocking teeth 31 and 32. At this time, the cam protrusions of one cam 27 are rotated. The bar 33 is folded to the cam interlocking projection 34 of the flat plate 17. When a rapid braking signal is transmitted in this state, the flat plate 17 is moved to the right, and the stop projection 5 and the stop are stopped. The function plate 17, which has been stopped by the pin 38, is released by rotating the stop lever 37 by the operation of the solenoid 41 according to the command of the control circuit section 42, so that the function plate 17 is a spring 18. The cam interlocking protrusion 34 pushes the cam protrusion 33 of one cam 27 while the cam interlocking protrusion 34 is rapidly moved to the right by the cam. As thereby the neutral return lever 7 to the neutral position (Fig. 4b the state).

따라서 본 고안에서는 공급릴(8)과 권취릴(10)을 구동시키던중, 즉 FF/REW중 급제동하는 경우 아이들러(6)가 공급아이들러(12) 또는 권취아이들러(13)에서 이탈되어 중립상태로 되므로 캡스탄 모터(1)가 전원차단후 관성력에 의해 계속 회전되더라도 그 회전력이 공급릴(8)과 권취릴(10)에 전달되지 않더라도 테이프의 손상, 늘어짐이나 절단을 방지할 수 있으며, 제동시간이 단축되어 정확한 위치에서 제동할 수 있고, 제품의 신뢰성 향상을 기할 수 있는 것이다.Therefore, in the present invention, while driving the supply reel 8 and the take-up reel 10, that is, during rapid braking during the FF / REW, the idler 6 is separated from the supply idler 12 or the winding idler 13 to a neutral state. Therefore, even if the capstan motor 1 is continuously rotated by inertial force after the power is cut off, even if the rotational force is not transmitted to the supply reel 8 and the take-up reel 10, the tape may be damaged, sag or cut, and the braking time may be prevented. This shortens the braking at the correct position and improves the reliability of the product.
