본 고안은 브이씨알의 공급릴과 권취릴을 선택적으로 구동시키는 릴구동용 클러치장치에 관한 것으로, 특히 브이씨알의 각 작동모드 즉, 재생모드, 빨리감기/빨리되감기모드, 큐/리뷰모드에 따라 각각 적절한 토르크로 공급릴 또는 권취릴을 구동토록 함과 아울러 부품관리 및 조립생산성을 향상시킬 수 있도록 한 브이씨알의 릴구동용 클러치장치에 관한 것이다.The present invention relates to a reel driving clutch device for selectively driving a V-Cell feed reel and a take-up reel, and in particular, according to each operating mode of the V-Cell, that is, a regeneration mode, a fast forward / fast rewind mode, and a cue / review mode. Each of the present invention relates to a V-RL reel driving clutch device for driving a supply reel or winding reel with an appropriate torque and improving part management and assembly productivity.

일반적으로 브이씨알에 있어서는 재생모드와 큐/리뷰모드 및 빨리감기/빨리되감기모드등의 작동모드가 있으며, 이들 각 모드별로 공급릴 또는 권치릴에 전달되는 토르크를 달리하여야 하며 특히 재생모드, 큐모드, 리뷰모드에서는 공급릴 또는 권취릴에 전달되는 토르크는 영상 및 음성에 매우 중요한 영향을 주게되는 것임은 주지하는 바이다.In general, there are operating modes such as play mode, cue / review mode, and fast-forward / fast-rewind mode, and the torque transmitted to the supply reel or winding reel is different for each mode. In the review mode, it is noted that the torque delivered to the supply or winding reel has a very important effect on the video and audio.

따라서 종래 브이씨알에서는 릴구동용 클러치장치를 적용하여 각 모드별로 적절한 토르크로 공급릴과 권취릴을 선택적으로 구동토록 하고 있다.Therefore, in the conventional VRC, a reel driving clutch device is applied to selectively drive the supply reel and the take-up reel with appropriate torque for each mode.

종래 길구동용 클러치장치로서는, 릴구동계통에 각각 재생 및 큐전용클러치장치와 리뷰전용클러치장치를 별도로 설치하여 공급릴과 권취릴을 각기 다른 전달계통에 의해 적절한 토르크로 전달하는 전용 클러치장치와, 단일 계통에 다수의 전달경로를 설치하여 각 모드별로 공급릴과 권취릴을 적절한 토르크로 전달케 한 겸용클러치장치가 사용되어 왔다.Conventionally, the clutch device for road driving includes a clutch device exclusively for regeneration and cue and a review clutch device separately installed in the reel drive system to deliver the supply reel and the take-up reel to the appropriate torque by different transmission systems; A combined clutch device has been used in which a plurality of transmission paths are installed in a single system so that the supply reel and the reel can be delivered to the appropriate torque in each mode.

전자의 전용클러치장치는, 공급릴과 권취릴측에 각각 동력전달용 구동기어와 피동측기어와 펠트 및 압축스프링으로 구성되는 클러치장치를 독립적으로 설치하여 각 모드에 따라 서로다르고 적절한 토르크가 전달되도록 한 것이다.The exclusive clutch device of the former is independently provided with a clutch device composed of a power transmission drive gear, a driven side gear, a felt and a compression spring on the supply reel and the reel side so that different and appropriate torques are transmitted according to each mode. will be.

그러나 이러한 전용클러치장치는, 공급릴과 권취릴측에 각기 설치되어 별도의 구분된 전동계통을 이루는 것이므로 브이씨알의 릴구동계통전체로 볼 때 부품수가 증가되고 이에따라 구조가 복잡하여 조립생산성이 저하되는 폐단이 있었다.However, such a dedicated clutch device is installed on the supply and winding reel side to form a separate electric system, so that the number of parts is increased in the whole of the reel driving system of V-Cal, and the structure is complicated, thus the assembly productivity is reduced. There was this.

또한 후자의 겸용클러치장치는 제1도에 도시한 바와같이, 공급릴과 권취릴(미도시)에 선택적으로 맞물리는 아이들러기어(1)가 선단에 굴대설치된 아이들러암(2)을 고정축(3)에 헐겁게 끼워 지지하고, 고정축(3)에는, 상기 아이들러기어(1)에 상시 맞물리는 아이들러구동기어(4)와 캡스턴모터(미도시)에 연동연결된 구동풀리(5) 및 클러치원판(6)을 각각 끼워 지지하여 상기 구동풀리(5)와 클러치원판(6) 사이에는 펠트(7)를 끼워 압착 스프링(8)으로 압착시키며 상기 구동기어(4)의 보스부에는, 상기 구동풀리(5)의 상면에 돌출된 계합돌기(5a)와 구동기어(4)에 형성된 계합홈(4a)에 맞물리는 계합돌편(10a)(10b)이 상하단에 형성된 동력전달절환풀리(9)를 승강가능하게 설치하여 절환레버(미도시)에 의해 승강작동토록 구성한 것이다.In addition, in the latter combined clutch device, as shown in FIG. 1, the idler arm 2 with the idler gear 1 selectively engaged with the supply reel and the winding reel (not shown) is fixed to the fixed shaft (3). The drive pulley (5) and the clutch disc (6) interlocked with the idler drive gear (4) and capstan motor (not shown), which are loosely fitted on the support shaft (3), and are always engaged with the idler gear (1). ) Are fitted to each other, and a felt 7 is inserted between the driving pulley 5 and the clutch disc 6 to be crimped with a pressing spring 8, and the driving pulley 5 is attached to the boss of the driving gear 4. The engaging projection 5a protruding from the upper surface of the c) and the engaging projection piece 10a, 10b engaged with the engaging groove 4a formed in the driving gear 4 are capable of raising and lowering the power transfer switching pulley 9 formed at the upper and lower ends thereof. It is installed so that the lifting operation by the switching lever (not shown).

이러한 겸용클러치장치는, 재생모드에서는 상기 동력전달 절환풀리(9)가 절환레버(미도시)에 의해 상승되어 하단의 계합돌편(10a)이 구동풀리(5)상면의 계합돌기(5a)에서 이탈된 상태로 되며, 이때의 동력전달은 구동풀리(5)에서 펠트(7)와 클러치원판(6) 및 압착스프링(8)을 통해 아이들러구동기어(4)에 전달되고 여기서 아이들러기어(1)에 전달되며 아이들러기어(1)는 권취릴(미도시)에 맞물려서 권취릴을 구동시켜 테이프(미도시)를 주행시킴으로써 재생작용이 이루어지게 되는 것이며, 한편 빨리감기/빨리되감기모드시에는 상기 동력 전달절환풀리(9)가 절환레버(미도시)에 의해 하강되어 그 하단의 계합돌편(10a)이 구동풀리(5)상면의 계합돌기(5a)에 맞물리게 되고, 이때의 동력전달은 구동풀리(5)에서 동력전달절환풀리(9)를 통해 직접적으로 아이들러구동기어(4)에 전달되며 여기서 아이들러기어(1)에 전달되고 아이들러기어(1)는 권취릴(미도시) 또는 공급릴(미도시)에 선택적으로 맞물려서 구동시키게 되는 것이다.In the combined clutch device, in the regeneration mode, the power transmission switching pulley 9 is lifted by a switching lever (not shown) so that the lower engaging projection piece 10a is separated from the engaging projection 5a on the upper surface of the driving pulley 5. At this time, the power transmission is transmitted from the driving pulley (5) to the idler drive gear (4) through the felt (7), the clutch disc (6) and the compression spring (8), where the idler gear (1) When the idler gear 1 is engaged with the winding reel (not shown) to drive the winding reel to drive the tape (not shown), the regeneration operation is performed, while the power transmission switching is performed during the fast forward / fast rewind mode. The pulley 9 is lowered by the switching lever (not shown) so that the engaging protrusion 10a at the lower end thereof engages with the engaging protrusion 5a on the upper surface of the driving pulley 5, and the power transmission at this time is driven by the driving pulley 5 Driven idler directly via power transfer pulley (9) Control is passed to (4) will be thereby transmitted to the idler gear (1) and wherein the idler gear (1) is selectively engaged to drive the take-up reel (not shown) or a feed reel (not shown).

그러나 이러한 겸용클러치장치는 전달되는 토르크를 크기가 다른 2종류로 밖에 전달할 수 없으므로 특히 재생 및 큐모드시에는 필요이상의 큰 토르크가 전달되어 부품의 치수관리, 조립상태관리가 되지 않으며 브이씨알의 기본성능은 물론이고 테이프까지 손상을 입히게 되는 등 각 모드에 따라 적절한 톨르크로 전달할 수 없으며, 부품의 치수관리와 조립상태관리가 난해하여 조립생산성이 저하되는 폐단이 있었다.However, the combined clutch device can only deliver the torque delivered in two different sizes. Especially during regeneration and cue mode, the large torque is transmitted more than necessary, so it is impossible to manage the dimensions of the parts and manage the assembly status. Of course, it could not be delivered to the appropriate toll according to each mode, such as damage to the tape.

따라서 본 고안은 상술한 종래의 제반폐단을 해소하기 위하여 안출된 것으로 브이씨알의 각 모드에 따라 적절한 토르크를 전달할 수 있으며 부품관리와 조립상태관리가 간편하고 조립생산성을 향상시킬 수 있도록 한 브이씨알의 릴구동용 클러치장치를 제공하려는 것이다.Therefore, the present invention has been devised to solve the above-mentioned conventional closures, and can transmit appropriate torque according to each mode of V-Cal. It is to provide a reel driving clutch device.
