본 고안은 구조를 간단히 하면서도 동작이 확실하고 압착상태가 양호하게 될 수 있도록 한 핀치롤러 구동장치에 관한 것이다.The present invention relates to a pinch roller drive device which can simplify the structure and ensure the operation and the compression state is good.
종래의 핀치롤러 구동장치를 보면, 로딩캠에 연결된 슬라이드 판체가 캠의 회전운동을 직선운동으로 바꿔주면서 슬라이드 판체에 형성시킨 기어로 핀치롤러암을 회동시켜 주고 이에따라 핀치롤러가 회동하여 캡스턴축에 압착되도록 구성되어 있었다.In the conventional pinch roller drive device, the slide plate connected to the loading cam rotates the cam rotation into linear motion, and the pinch roller arm is rotated by the gear formed on the slide plate. It was configured to be.
그러나, 이와같은 종래의 것은 핀치롤러를 구동시키기 위하여 캠의 회전운동을 직선운동으로 이를 다시 회전운동으로 바꿔주어야 하므로서 여러 동작을 일치시켜야 하는 문제가 있었고, 또 이를 위한 여러부품을 일관성있게 연결설치해야 하므로서 구조가 복잡하게 되고 고장발생률이 증대되었으며 작동이 원활하게 되지 못하는 점등의 문제점이 있었다.However, in the related art, in order to drive the pinch roller, there is a problem in that the motions of the cams need to be matched by changing the rotational movements of the cams into linear motions and back to rotational motions. As a result, the structure is complicated, the failure rate is increased, and there is a problem of lighting that does not operate smoothly.
본 고안은 상기와 같은 종래의 제반문제점을 감안하여 안출한 것으로 이를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been devised in view of the above-mentioned conventional problems, and will be described in detail with reference to the accompanying drawings.
즉, 1은 데크로서 일단에 원호상 가이드장공(2)을 형성하고 이의 일측에 캠기어(3)를 설치하여 캠기어(3)의 일측에는 기어축(5)에 설치되는 연결기어(4)를 맞물리도록 설치한다.That is, 1 is a deck formed with an arc-shaped guide long hole (2) at one end and the cam gear (3) is installed on one side thereof, the coupling gear (4) is installed on the gear shaft (5) on one side of the cam gear (3) Install to interlock.
6은 구동기어로서 기어축(7)에 설치되고 연결기어(4)에 맞물리며 이의 상면에 캠(8)을 설치한다.6 is installed in the gear shaft (7) as a drive gear, meshes with the connecting gear (4) and installs a cam (8) on its upper surface.
9는 암축으로서 이에 핀치롤러암(11)이 톨션스프링(10)으로 탄력설치되고 핀치롤러암(11) 저면부에는 상기 가이드 장공(2)에 삽입되는 돌출부(12)가 형성되며 일단에 핀치롤러(14)가 설치되는 핀치롤러측(13)이 형성되어 있다.9 is an arm shaft, and the pinch roller arm 11 is elastically installed with the torsion spring 10, and the bottom portion of the pinch roller arm 11 is provided with a protrusion 12 inserted into the guide hole 2, and the pinch roller at one end thereof. The pinch roller side 13 on which the 14 is provided is formed.
톨션스프링(10)의 일단은 데크(1)에 고정되고 탄력은 핀치롤러암(11)에 설치된다.One end of the torsion spring 10 is fixed to the deck 1, the elasticity is installed on the pinch roller arm (11).
15는 스프링 설치판으로서 이의 일단에 스프링핀(16)과 스프링가이드(17)가 형성되고 스프링지지판(18)이 결합되며 스프링핀(16)에 압축스프링(19)이 탄력설치되고 암축(9)에 유설된다.15 is a spring mounting plate, the spring pin 16 and the spring guide 17 is formed at one end thereof, the spring support plate 18 is coupled, the compression spring 19 is elastically installed on the spring pin 16 and the female shaft 9 Is vulnerable to.
상기 캠(8)은 핀치롤러암(11)의 일측에 접설되고 볼트(20)와 와셔(21)는 핀치롤러암(11)과 스프링설치판(15)을 암축(9)에 체결시키며 스냅링(22)은 각각의 연결기어(4)와 구동기어(6)을 기어축(5)(7)에 설치시키는 것으로 미설명부호 23은 캡스턴축이다.The cam 8 is connected to one side of the pinch roller arm 11, and the bolt 20 and the washer 21 fasten the pinch roller arm 11 and the spring mounting plate 15 to the arm shaft 9, 22) is to install each of the connecting gear (4) and the drive gear (6) to the gear shaft (5) (7), reference numeral 23 is a capstan shaft.
이상과 같이 구성된 본 고안은 제3도에서와 같이 캠기어(3)가 구동함에 따라 연결기어(4)가 회동하면서 캠(8)의 회동에 의해 스프링지지판(18)을 밀게 되어 톨션스프링(10)보다 탄성이 강한 압축스프링(19)을 적은 힘으로 압착하며 핀치롤러암(11)을 캡스턴축(23)에 이동시키며, 계속 캠(8)이 회동하게 되면 캠곡선의 가장 바깥면에서 스프링지지판(18)을 더욱 압착하게 되면 압축스프링(19)이 압착되어 스프링의 탄성력에 비례하는 힘으로 핀치롤러(14)를 캡스턴축(23)에 압착하게 된다.The present invention configured as described above, as the cam gear 3 is driven as shown in FIG. 3, as the connecting gear 4 is rotated, the spring support plate 18 is pushed by the rotation of the cam 8, and the torsion spring 10 The compression spring 19, which is more elastic than the above, is pressed with a small force, and the pinch roller arm 11 is moved to the capstan shaft 23. When the cam 8 continues to rotate, the spring support plate is formed on the outermost surface of the cam curve. When the 18 is further compressed, the compression spring 19 is compressed to compress the pinch roller 14 to the capstan shaft 23 with a force proportional to the elastic force of the spring.
한편, 언로딩동작을 하기 위하여 캠기어(3)를 역회전시키면, 연결기어(4)와 구동기어(6)가 상기의 역으로 회동되고 캠(8)이 복귀되며 핀치롤러암(11)은 톨션스프링(10)의 탄력으로 복귀되면서 캡스턴축(23)에 압착되어 있던 핀치롤러(14)를 복귀시켜준다.On the other hand, when the cam gear 3 is rotated in reverse for the unloading operation, the connecting gear 4 and the drive gear 6 are rotated in the reverse direction, the cam 8 is returned, and the pinch roller arm 11 is The pinch roller 14, which has been compressed to the capstan shaft 23, is returned while returning to the elasticity of the torsion spring 10. FIG.
이때, 핀치롤러암(11)의 저면부에 형성된 돌출부(12)는 데크(1)의 가이드 장공(2)을 따라 이동하여 핀치롤러암(11)의 과동작을 방지시켜주며 압축스프링(19)과 스프링설치판(15)에 설치된 스프링지지판(18)도 원상으로 복귀된다.At this time, the protrusion 12 formed on the bottom portion of the pinch roller arm 11 moves along the guide hole 2 of the deck 1 to prevent over-operation of the pinch roller arm 11 and the compression spring 19 And the spring support plate 18 provided on the spring mounting plate 15 are also returned to their original shape.
이상과 같이 본 고안은 간단한 구조로서 핀치롤러의 구동을 확실하고 안정성있게 행할 수 있고 이의 압착상태를 양호하게 할 수 있으며 동작이 원활하고 고장이 발생될 염려가 거의 없는 점등의 특징을 지닌 것이다.As described above, the present invention has a simple structure, which enables the pinch roller to be driven reliably and stably, and its crimping state can be improved, and the operation is smooth and there is little fear of failure.
