본 고안은 브이씨알의 펀치로울러 압착장치에 관한 것으로 특히 캡스턴에 대한 핀치로울러의 압착 및 이탈작동이 원활하게 이루어지면서도 소형화 및 부품수 절감을 기할 수 있도록 한 브이씨알의 핀치로울러 압착장치에 관한 것이다.The present invention relates to a punch roller pressing device of V-Cal, and more particularly to a pin-rolling roller pressing device of V-AL which enables the miniaturization and the reduction of the number of parts while the pinch roller is easily pressed and released from the capstan. .
종래 브이씨알의 핀치로울러 압착장치는, 제1도에 도시한 바와 같이 캡스턴(22)에 접탈되는 핀치로울러(21)를 중간부가 힌지로 지지된 대략 ㄱ자형 핀치암(23)의 선단에 굴대설치하되 핀치암(23)의 후단부를 하나의 배력기구(Toggle Mechanism)를 구성하는 3개의 레버(24)(25)(26)중 전방측 레버(24)에 힌지연결하고, 상기 중간측레버(25)에는 펑션플레이트(27)에 연동되는 연동암(28)의 선단을 힌지연결하며, 상기 후방측레버(26)에는 스프링(29)으로 탄력설치된 압착암(30)을 힌지연결한 구조이다.Conventional V-Cal pinch roller pressing device, as shown in FIG. 1, mandrel the pinch roller 21 detachably attached to the capstan 22 to the tip of the approximately L-shaped pinch arm 23 whose middle portion is supported by the hinge. However, the rear end of the pinch arm 23 is hinged to the front lever 24 of the three levers 24, 25 and 26 constituting one force mechanism (Toggle Mechanism), and the intermediate lever 25 ) Is hinged to the front end of the linkage arm 28 that is linked to the function plate 27, the rear lever 26 is hinged to the compression arm 30 is elastically installed by the spring (29).
이러한 종래의 핀치로울러 압착장치는, 제1도 (a)에 도시한 바와 같이 캡스턴(22)에서 핀치로울러(21)가 이탈된 상태에서 캠기어(미도시)에 연동하여 펑션플레이트(27)가 좌측으로 이동하면 연동암(28)이 시계방향으로 회동하면서 중간측레버(25)를 우측으로 당기게 되며 이에 따라 압착암(30)과 핀치암(23)이 반시계 방향으로 회동되어 제1도 (b)와 같이 캡스턴(22)에 압착되는 순간 부트는 핀치암(23)의 움직임이 정지되고 이상태에서 펑션플레이트(27)의 추가이동에 의해 각 부품이 추가로 회동되면서 압착암(30)의 일단에 탄력 설치된 스프링(29)의 탄력을 증가시키게 되며, 이때의 스프링(29)의 힘에 의한 각 부품들의 반력이 핀치암(23)에 회전모멘트로 전달되어 핀치로울러(21)의 캡스턴(22)에 대한 압착력을 발생시키게 되는 것이다.In the conventional pinch roller pressing device, as shown in FIG. 1 (a), the function plate 27 is interlocked with a cam gear (not shown) in a state where the pinch roller 21 is separated from the capstan 22. When moving to the left, the interlocking arm 28 rotates in the clockwise direction and the middle lever 25 is pulled to the right. As a result, the pressing arm 30 and the pinch arm 23 rotate in the counterclockwise direction. The moment the boot is compressed to the capstan 22 as shown in b), the movement of the pinch arm 23 is stopped, and in this state, each part is additionally rotated by the additional movement of the function plate 27 so that one end of the crimp arm 30 can be rotated. Resilience of the spring 29 is installed to increase the elasticity, the reaction force of each part by the force of the spring 29 at this time is transmitted to the pinch arm 23 as a rotation moment to the capstan 22 of the pinch roller 21 It will generate a pressing force for.
한편 제1도 (b)의 압착상태에서 펑션플레이트(27)가 우측으로 이동되면 상술한 압착작동과 역방향으로 작동하여 캡스턴(22)에서 핀치로울러(21)가 이탈되는 것이다.On the other hand, when the function plate 27 is moved to the right in the crimped state of FIG. 1 (b), the pinch roller 21 is separated from the capstan 22 by operating in the opposite direction to the crimping operation described above.
그러나 이러한 종래의 핀치로울러 압착장치는, 그 구성 부품수가 많고 복잡하며 소형 경량화에 불리하다고 하는 페단이 있었다.However, such a conventional pinch roller crimping device has a pedan, which is said to have a large number of components and is complicated and disadvantageous in miniaturization and light weight.
따라서 본 고안은 상술한 종래의 페단을 해소하여 핀치로울러의 압착 및 이탈작동이 원활하게 이루어지면서도 부품수를 절감시킬 수 있으며 소형경량화를 기할 수 있도록한 브이씨알의 핀치로울러 압착장치를 제공하려는 것이다.Accordingly, the present invention is to provide a pinch roller pressing device of V-CAL which can reduce the number of parts and reduce the number of parts while making the pinch roller press and release operation smooth by eliminating the above-described conventional pedan. .
이하 본 고안에 의한 브이씨알의 핀치로울러 압착장치를 첨부도면에 도시한 일실시예에 따라서 상세히 설명한다.Hereinafter, a pinch roller compaction apparatus of V-Cal according to the present invention will be described in detail according to an embodiment shown in the accompanying drawings.
본 고안의 핀치로울러 압착장치는, 제2도 및 제3도에 도시한 바와 같이 핀치로울러(1)를 펑션플레이트(2)에 연동하여 캡스턴(3)에 압착 및 이탈시키는 것에 있어서, 상기 핀치로울러(1)가 선단에 굴대설치되는 핀치암(4)의 후단부를 분지하여 지지부(5)와 연동부(6)를 형성하고, 그 지지부(5)를 베이스(7)에 힌지로 지지하며, 상기 펑션플레이트(2)에 연동되는 핀치레버(8)를 상기 핀치암(4)과 동축으로 지지하고, 핀치레버(8)의 측부에는 상기 핀치암(4)의 연동부(6)에 접하는 연동부(9)를 형성하며, 상기 핀치암(4)과 핀치레버(8)사이에는 압착용 토션스프링(10)을 설치하고, 상기 핀치암(4)의 측방에는 복귀용스프링(11)을 설치하여서 된 것이다.In the pinch roller pressing device of the present invention, as shown in FIGS. 2 and 3, the pinch roller 1 is connected to the function plate 2 to press and release the pinch roller to the capstan 3. (1) branches off the rear end of the pinch arm (4) that is mandreled at the tip to form the support part (5) and the linkage part (6), and supports the support part (5) to the base (7) by a hinge; An interlocking portion supporting the pinch lever 8 interlocked with the function plate 2 coaxially with the pinch arm 4, and in contact with the interlocking portion 6 of the pinch arm 4 on the side of the pinch lever 8. (9), a torsion spring (10) for compression is installed between the pinch arm (4) and the pinch lever (8), and a return spring (11) is provided on the side of the pinch arm (4). It is.
상기 핀치암(4)의 지지부(5)에는 보스(12)를 형성하여 베이스(7)에 고정된 지지축(13)에 지지하며, 상기 핀치레버(8)에는 상기 핀치암(4)의 보스(12)에 겉으로 끼워지는 보스(14)를 형성하여 핀치암(4)과 핀치레버(8)를 동축으로 지지하는 것이다.A boss 12 is formed on the support 5 of the pinch arm 4 to support the support shaft 13 fixed to the base 7, and the boss of the pinch arm 4 is supported on the pinch lever 8. A boss 14 fitted to the outer surface 12 is formed to support the pinch arm 4 and the pinch lever 8 coaxially.
상기 압착용 토션스프링(10)은 상기 핀치레버(8)의 보스(14)에 감아끼워 양측 스프링암을 각각 핀치암(4)가 핀치레버(8)에 돌출된 스프링걸이(15)(16)에 걸어서 핀치암(4)이 상시 압착상태로 탄력설치한다.The crimping torsion spring 10 is wound around the boss 14 of the pinch lever 8 so that the spring hooks 15 and 16 of which both pinch arms 4 protrude from the pinch lever 8 respectively. The pinch arm (4) is elastically installed in a crimped state at all times.
상기 압착용 토션스프링(10)은 복귀용스프링(11)보다 탄성력이 강한 것을 사용한다.The compression torsion spring 10 uses a stronger elastic force than the return spring (11).
미설명 부호 17은 펑션플레이트(2)에 돌출된 펑션핀이다.Reference numeral 17 is a function pin protruding from the function plate (2).
이와 같이 구성된 본 고안의 핀치로울러 압착장치는, 제2도 (a)에 도시한 핀치로울러 압착전 상태 즉, 핀치로울러(1)가 캡스턴(3)에서 이탈된 상태에서 캠기어(미도시)에 의하여 펑션플레이트(2)가 우측으로 이동되면 펑션핀(17)에 의해 핀치레버(8)가 반시계 방향으로 회동되며, 이에따라 펑션암(4)이 토션스프링(10)을 통해 연동되어 시계방향으로 회동되면서 핀치로울러(1)가 캡스턴(3)에 밀착된다.In the pinch roller pressing device of the present invention configured as described above, the pinch roller pressing state as shown in FIG. 2 (a) is applied to the cam gear (not shown) in the state before the pinch roller pressing, that is, the pinch roller 1 is separated from the capstan 3. When the function plate 2 is moved to the right side, the pinch lever 8 is rotated counterclockwise by the function pin 17. Accordingly, the function arm 4 is interlocked through the torsion spring 10 in the clockwise direction. While rotating, the pinch roller 1 comes into close contact with the capstan 3.
이상태에서는 핀치로울러(1)가 캡스턴(3)에 의해 정지되어 핀치암(4)은 더이상 회동되지 않으며, 펑션플레이트(1)의 추가이동에 따라 핀치레버(8)가 추가로 회동되고 이에 따라 토션스프링(10)의 탄성력을 증가시키게 되어 핀치로울러(1)는 캡스턴(3)에 압착되는 것이다(제2도 (b)참조).In this state, the pinch roller 1 is stopped by the capstan 3 and the pinch arm 4 is no longer rotated. As the function plate 1 is further moved, the pinch lever 8 is additionally rotated and the torsion accordingly. The pinch roller 1 is pressed against the capstan 3 by increasing the elastic force of the spring 10 (see FIG. 2 (b)).
다음 제2도 (b)의 상태에서 펑션플레이트(2)가 좌측으로 이동되면 핀치암(4)과 핀치레버(8)의 연동부(6)(9)가 접촉되기전에는 핀치레버(8)가 펑션핀(17)에 밀착된 상태에서 핀치레버(8)만 반시계 방향으로 회동되며 연동부(6)(9)가 접촉되는 순간부터 핀치로울러(1)의 캐스턴(3)에 대한 압착력이 완전히 해제되고 이때의 압착용이 토션스프링(10)의 탄성력은 복귀용스프링(11)의 복원력보다 약화된 상태이므로 스프링(11)에 의하여 핀치암(4)와 핀치로울러(1)가 제2도 (a)상태로 복귀되는 것이다.Next, when the function plate 2 is moved to the left in the state of FIG. 2 (b), the pinch lever 8 is closed before the pinch arm 4 and the linkage part 6 and 9 of the pinch lever 8 come into contact with each other. Only the pinch lever 8 is rotated counterclockwise in a state in which it is in close contact with the function pin 17, and the pressing force of the pinch roller 1 to the caster 3 from the moment when the interlocking parts 6 and 9 are contacted Since the elastic force of the torsion spring 10 is completely weakened and the compression force of the torsion spring 10 is weaker than the restoring force of the return spring 11, the pinch arm 4 and the pinch roller 1 are driven by the spring 11. a) to return to the state.
이상과 같이 본 고안에 의하면 캣스턴에 대한 핀치로울러의 압착 및 이탈작동이 원활하게 이루어지면서도 부품수가 절감되고 소형경량화를 기할 수 있으며, 조립의 간편화를 도모할 수 있고 공간을 효율적으로 활용할 수 있는 것이다.As described above, according to the present invention, the pinch rollers can be smoothly pressed and released, and the number of parts can be reduced, the weight and weight can be reduced, the assembly can be simplified, and the space can be efficiently will be.
