It relates to an arm drive device.
종래 기술의 릴브레이크 및 텐션암구동장치는 그 전형 적인 형태를 제1도에서 보인 바와같이 공급릴(1)에 소프트 브레이크(2)와 메인브레이크(3)가 작용하고 권취릴(4)에는 한쌍의 소프트브레이크(5), (6)와 메인브레이크(7)가 작용토록 되어 있으며 소프트브레이크(2), (5), (6)은 캠홈(8a)을 보유하는 캠(8)으로부터 중간레버(9), (10)를 통하여 연결되어 구동되는 서브-펑션플레이트(sub-function plat)(11)에 의하여 구동되고, 메인브레이크(3), (7)는 캠(8)으로부터 중간레버(12), (13), (14)를 통하여 연결된 메인펑션플레이트(5)에 의하여 구동된다.The reel brake and tension arm drive of the prior art have a soft brake 2 and a main brake 3 acting on the supply reel 1 and a pair of winding reel 4 as shown in FIG. Soft brake (5), (6) and the main brake (7) is to act, the soft brake (2), (5), (6) is from the cam (8) having the cam groove (8a) intermediate lever ( 9), driven by a sub-function plat 11 connected and driven through (10), the main brakes (3), (7) from the cam (8) to the intermediate lever (12) It is driven by the main function plate (5) connected via, (13), (14).
또한 텐션포스트(16)를 재가한 텐션암(17)은 다른 두 개의 중간레버(18), (19)에 의하여 플레이모드와 리뷰모드시에 서브-펑션플레이트(11)에 의하여 구동된다.In addition, the tension arm 17 having the tension post 16 re-driven is driven by the sub-function plate 11 in the play mode and the review mode by the other two intermediate levers 18 and 19.
그러나 이와같은 종래 기술은 텐션암과 소프트브레이크를 구동시키기 위하여 많은 수의 중간레버와 서브-펑션플레이트를 사용하고 역시 메인브레이크를 구동시키기 위하여 많은 수의 중간레버를 사용함으로써 부품수가 증가되고 동작도 복잡한 결점이 있었다.However, this prior art uses a large number of intermediate levers and sub-function plates to drive tension arms and soft brakes, and also uses a large number of intermediate levers to drive main brakes. There was a flaw.
따라서 본 고안은 종래의 이와같은 결점을 해소하기 위하여 안출한 것으로 간단한 구조의 릴브레이크와 텐션암의 구동장치를 제동하는데 그 목적이 있는 것인바, 이를 첨부 도면에 의거하여 보다 상세히 설명하면 다음과 같다.Therefore, the present invention has been made in order to solve such a drawback of the related art, and has the purpose of braking a drive device of a reel brake and a tension arm having a simple structure, which will be described in more detail based on the accompanying drawings. .
본 고안의 릴브레이크 및 텐션암 구동장치는 제2도에 도시한 바와 같이 공급릴(21)과 권취릴(22)이 설착되고, 공급릴(21)에는 밴드브레이크(23)가 환착되어 그 일측단이 축(24)으로 축설되고 경사포스트 조립체(25)가 접촉하는 부위인 선단에 텬션포스트(26)가 입설된 텐션암(27)에 착설되며, 이 텐션암(27)은 스프링(28)에 의하여 반시계반대 방향으로 회전토록 탄지되고, 공급릴(21)과 권취릴(22)에 인접하여 메인펑션플레이트(29)가 이에 형성된 안내로(30), (30')에 안내봉(31), (31')이 삽입되어 좌우 이동하게 배치되고 이 메인 펑션플레이트(29)가 캠홈(32a)을 보유하는 캠(32)으로부터 제1 및 제2중간레버(33), (34)로 연결되며, 공급릴(21)과 권취릴(22)에는 샤시(도시하지 않았음)에 축설된 소프트브레이크(35), (36)와 메인브레이크(37), (38)가 작용토록된 것에 있어서, 공급릴(21)의 소프트블레이크(35)와 메인브레이크(37), 그리고 권취릴(22)의 메인브레이크(38)은 이들의 후단에 입설된 핀(35a), (37a), (38a)을 메인펑션플레이트(29)에 지지하고 하강력(39), (40), (41)을 각각 갖는 안내구(42), (43), (44)에 삽입하고, 권취릴(22)의 소프트브레이크(36)는 그후단에 입설된 핀(36a)이 메인펑션플레이트(29)의 후단에서 외향돌출되고 경사턱(45)을 갖는 돌편(46)에 접촉토록하며, 각 소프트브레이크(35), (36)와 메인브레이크(37), (38)는 토션스프링(47), (48)으로 탄지하고, 메인펑션플레이트(29)의 선단에는 안내핀(49)을 입설하여 텐션암(27)의 후단접촉부(50)와 접촉케 하여서된 구조이다.In the reel brake and tension arm driving device of the present invention, as shown in FIG. 2, a supply reel 21 and a winding reel 22 are installed, and a band brake 23 is returned to the supply reel 21, and one side thereof. The tension arm 27 is mounted on the tension arm 27 with the end post erected by the shaft 24 and the suction post 26 at the tip end of the inclined post assembly 25. By the counterclockwise rotation by the counterclockwise direction, the main function plate 29 is formed adjacent to the supply reel 21 and the take-up reel 22, the guide rods 31 and 30 ' ), (31 ') are inserted and disposed to move left and right, and the main function plate 29 is connected from the cam 32 holding the cam groove 32a to the first and second intermediate levers 33 and 34. In the supply reel 21 and the take-up reel 22, the soft brakes 35, 36 and the main brakes 37, 38 arranged in the chassis (not shown) are allowed to act. Feeding reel ( The soft brake 35 and the main brake 37 of the 21 and the main brake 38 of the winding reel 22 have pins 35a, 37a and 38a mounted on their rear ends of the main function plate. Soft brakes 36 of the take-up reel 22 are inserted into guides 42, 43, and 44 that support the support 29 and have lowering force 39, 40, and 41, respectively. The pin 36a placed at the rear end protrudes outwardly from the rear end of the main function plate 29 and contacts the protrusion piece 46 having the inclined jaw 45, and each of the soft brakes 35, 36 and Main brakes (37) and (38) are supported by torsion springs (47) and (48), and guide pins (49) are inserted into the front end of main function plate (29) to contact the rear end of the tension arm (27) (50). ) Is in contact with the structure.
이와같은 본 고안은 제2도에서 정지모우드를 보이고 있으며, 플레이모우드시에는 캠(32)이 회전하고 제1 및 제2중간레버(33), (34)를 통하여 메인펑션플레이트(29)가 우측으로 이동한다.The present invention shows a stationary mode in FIG. 2, and during play mode, the cam 32 rotates and the main function plate 29 is right through the first and second intermediate levers 33 and 34. Go to.
이에 따라서 안내구(42), (43), (44)의 하강턱(39), (41)의 하측에 위치하던 공급릴(21)의 소프트브레이크(35)와 메인브레이크(37)의 후단 핀(35a), (37a)와, 권취릴(22)의 메인브레이크(38)의 후단핀(38a)이 안내구(42)에서 하강턱(39), (40), (41)의 상측으로 위치가 옮겨져 각 브레이크(35), (37), (38)이 해제되고 또한 메인펑션플레이트(29)의 후단에 돌출된 돌편(46)의 경사턱이 권취릴(22)의 소프트브레이크(36)에 입설된 핀(36a)에 접하여 이를 상측으로 밀어올려 소프트레이크(36)를 해제 하여 플레이 기능을 수행한다.Accordingly, the soft brake 35 and the rear pin of the main brake 37 of the supply reel 21, which are located below the lowering jaws 39, 41 of the guides 42, 43, and 44, respectively. (35a), (37a) and the rear end pin (38a) of the main brake (38) of the take-up reel (22) are positioned above the lower jaw (39), (40), (41) in the guide port (42). Is moved to release the respective brakes 35, 37, and 38, and the inclined jaw of the projection piece 46 projecting to the rear end of the main function plate 29 is applied to the soft brake 36 of the take-up reel 22. Contact the standing pin (36a) and push it upwards to release the soft lake 36 to perform a play function.
이때 텐션측에서는 메인펑션플레이트(29)가 우측으로 이동하여 그 선단측의 안내핀(49)이 우측으로 이동하여 텐션암(27)의 후단접촉부(50)가 이로부터 해지되어 텐션암(27)은 스프링(28)의 힘에 의해 반시계방향으로 회전하여 텐션포스트(26)를 지나는 테이프의 텐션을 조절하는 것이다.At this time, at the tension side, the main function plate 29 moves to the right side, the guide pin 49 on the tip side moves to the right side, and the rear end contact portion 50 of the tension arm 27 is released from the tension arm 27. The force of the spring 28 rotates counterclockwise to adjust the tension of the tape passing through the tension post 26.
이와같은 본 고안의 종래 기술에 비하여 부품수가 현저히 적으면서도 모든 모우드의 수행이 간단히 이루어질 수 있는 이점이 있는 것이다.Compared with the prior art of the present invention as described above, there is an advantage that the performance of all the modes can be made simple while significantly reducing the number of parts.
