본 고안은 브이씨알의 텐션조절장치에 관한 것으로, 특히 텐션조절이 더욱 정확하고 소형화를 이룰 수 있도록 한 브이씨알의 텐션조절장치에 관한 것이다.The present invention relates to a tension control device of V-Cal, and more particularly, to a tension control device of V-Cal which enables tension adjustment to be more accurate and compact.
종래 브이씨알의 테이프 주행계는 제1도에 도시한 바와같이 공급릴(1)에서 풀리는 테이프(2)가 회전헤드드럼(3)을 거쳐 권취릴(4)에 감기도록 구성하거나 그 반대방향으로 주행하도록 되어 있으며, 주행하는 테이프(2)에 항상 일정한 텐션이 유지되도록 텐션조절장치가 구비되어 있다.Conventional V-Ray tape traveling system is configured such that the tape 2 released from the supply reel 1 is wound on the take-up reel 4 via the rotating head drum 3 as shown in FIG. It is made to travel, and the tension control apparatus is provided so that constant tension may be always maintained in the tape 2 which travels.
종래의 텐션조절장치는 제2도에 도시한 바와 같이 텐션암(5)이 베이스 플레이트에 회전점(6)을 중심으로 회전하게 되어 있고, 텐션밴드(7)의 일단이 텐션암(5)에 연결됨과 아울러 타단은 베이스플레이트에 고정되어 공급릴(1)을 소정 각도만큼 감고 있다.In the conventional tension control device, as shown in FIG. 2, the tension arm 5 rotates around the rotation point 6 on the base plate, and one end of the tension band 7 is connected to the tension arm 5. In addition, the other end is fixed to the base plate is wound around the supply reel (1) by a predetermined angle.
제1도 및 제1도에서 미설명 부호 8은 텐션암(5)을 반시계방향으로 탄지하는 스프링, 9는 텐션포스트, 10은 소거헤드, 11은 임피던스롤, 12는 로딩포스트, 13은 A/C헤드, 14는 핀치롤, 15는 캡스턴을 각각 보인 것이다.In FIG. 1 and FIG. 1, reference numeral 8 denotes a spring which holds the tension arm 5 counterclockwise, 9 is a tension post, 10 is an erase head, 11 is an impedance roll, 12 is a loading post, 13 is A / C head, 14 is pinch roll, 15 is capstan.
상기한 바와 같은 종래의 텐션조절장치는 테이프 주행시(Play) 테이프(2)의 텐션변화에 따라서 테이프(2)의 텐션을 조절하게 되는 바, 테이프(2)의 텐션이 커지면 텐션포스트(9)는 회전점(6)을 중심으로 시계방향으로 움직여서 텐션밴드(7)를 풀어주어 테이프(2)의 텐션을 감소시키고, 테이프(2)의 텐션이 작아지면 스프링(8)의 힘에 의하여 회전점(6)을 중심으로 반시계방향으로 회전하여 테이프(2)의 텐션을 증가시키며, 이러한 동작을 계속하여 테이프(2)의 텐션을 일정하게 유지시켜 준다.In the conventional tension control device as described above, the tension of the tape 2 is adjusted according to the change in the tension of the tape 2 when the tape runs. When the tension of the tape 2 increases, the tension post 9 The tension band 7 is released by moving clockwise around the rotation point 6 to reduce the tension of the tape 2, and when the tension of the tape 2 decreases, the rotation point ( It rotates counterclockwise around 6) to increase the tension of the tape 2, and this operation is continued to keep the tension of the tape 2 constant.
그러나 종래의 장치에 있어서는 텐션밴드가 공급릴을 감는 각이 작아서 텐션의 변화에 민감하지 못하고 텐션밴드의 일단을 베이스플레이트상에 부착함으로써 그 만큼 설치면적을 차지하게 되고 텐션밴드가 구부러지는 등의 우려가 있으며, 조립성이 저하되는 문제점이 있었다.However, in the conventional apparatus, the tension band is wound around the supply reel so that it is not sensitive to the change of tension, and one end of the tension band is attached to the base plate to occupy the installation area and the tension band may be bent. There was a problem that the assembly performance is lowered.
본 고안은 상기한 바와 같은 종래의 문제점을 해결하기 위하여 안출한 것으로, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is devised to solve the conventional problems as described above, it will be described in detail by the accompanying drawings as follows.
제3도 내지 제5도에 도시한 바와 같이 고정편(21, 22)이 양쪽에 형성되고, 연장부(23)에 안내장공(24)이 형성된 밴드홀더(25)의 양쪽 고정편(21, 22)에 텐션밴드(7)의 양단부를 고정하고, 그 밴드홀더(25)의 안내장공(24)에는 텐션암(5)의 중간부에 고정한 연결핀(26)을 삽입하며, 공급릴(1)의 주위에는 텐션밴드(7)가 느슨해졌을 때 벗어나지 않도록 가이드(27)를 설치하여서 된 것이다.As shown in FIGS. 3 to 5, both fixing pieces 21 of the band holder 25 having the fixing pieces 21 and 22 formed on both sides and the guide hole 24 formed on the extension 23 are provided. 22, both ends of the tension band 7 are fixed, and the connecting pin 26 fixed to the middle part of the tension arm 5 is inserted into the guide hole 24 of the band holder 25, and the supply reel 1 The guide band 27 is provided so that the tension band 7 does not escape when the tension band 7 is loosened.
도면에서 미설명 부호 1a는 공급릴(1)의 주면에 형성된 텐션밴드 삽입홈을 보인 것이고 그외의 구성은 종래의 구성과 같다.In the drawings, reference numeral 1a shows a tension band insertion groove formed on the main surface of the supply reel 1, and the rest of the configuration is the same as the conventional configuration.
이와 같이 구성된 본 고안의 장치는 브이씨알 작동시 테이프(2)의 텐션이 커지면 텐션포스트(9)가 회전점(6)을 중심으로 시계방향으로 회전하면서 텐션밴드(7)를 공급릴(1)에서 풀어주어 텐션을 약하게 하고 텐션암(5)은 스프링(8)의 힘에 의하여 힌지점(6)을 중심으로 반시계방향으로 움직이는 순간적인 동작을 하게 되어 테이프의 텐션을 일정하게 유지시켜 준다.The device of the present invention configured as described above supplies the tension band 7 while the tension post 9 is rotated clockwise around the rotation point 6 when the tension of the tape 2 increases during the VRC operation. Release the tension to weaken the tension arm (5) by the force of the spring (8) to move the moment around the hinge point (6) counterclockwise to maintain a constant tension of the tape.
또한 테이프(2)의 언로딩시 텐션암(5)이 통상의 로딩기구에 연동하여 시계방향으로 회동할 때 텐션암(5)에 부착되너핀(26)이 밴드홀더(25)의 안내장공(24)을 따라서 움직이므로 텐션밴드(7)가 구부러짐이 없이 자연스런 상태를 유지하게 된다.In addition, when the tension arm 5 is rotated clockwise in conjunction with a normal loading mechanism when the tape 2 is unloaded, the inner pin 26 is attached to the tension arm 5 to guide holes of the band holder 25. Moving along 24), the tension band 7 maintains its natural state without bending.
상기한 바와 같은 본 고안의 장치를 적용하면 텐션밴드(7)가 공급릴(1)을 감는 각이 종래의 경우보다 커지므로(θ>θ) 텐션변화에 보다 민감하게 작용할 수 있으며, 텐션밴드(7)의 한쪽을 베이스플레이트에 고정하지 않으므로 설치면적이 적어지고 텐션밴드의 구부러짐이 해소되며, 조립성이 향상되는 등의 잇점이 있다.By applying the device of the present invention as described above, since the tension band (7) winding the supply reel (1) is larger than the conventional case (θ> θ) can act more sensitive to the tension change, the tension band ( Since one side of 7) is not fixed to the base plate, there is an advantage that the installation area is reduced, the bending of the tension band is eliminated, and the assemblability is improved.
