In particular, the connecting pin of the pressing lever is integrated with the cam lever while connecting a simplified pressing lever using a tension coil spring between the cam lever connected to the cam gear and the pinch roller arm. It relates to a pinch roller crimping device that can be easily assembled using a mold hook formed with a.
종래의 핀치롤러 압착 장치는 제1도에 도시한 바와 같이, 캠기어(1)의 캠홈(1a)에는 고정힌지점(2)을 갖는 캠레버(3)의 접동핀(3a)이 삽입되고 있고, 핀치롤러(4)가 일측단부 유착된 핀치롤러암(5)이 고정 힌지점(6)으로 축착되어 있으며, 캠레버(3)와 핀치롤러암(5)의 사이에는 압축 코일 스프링(7)을 이용한 압착레버(8)가 연결되어 있다. 이 압착레버(8)는 제2도를 참조하면, 압착레버(8)의 상하로 겹쳐지는 2개의 판(8')(8")에는 중간부에 삽입공(8'a)(8"a)이 천공되고 그 삽입공(8'a)(8"a)에는 압축 코일 스프링(7)이 삽입됨과 아울러 판(8')(8") 외측부에는 압축코일 스프링(7)의 이탈을 방지하기 위하여 양단이 절곡되는 이탈 방지편(9)(9')을 스프링(7)의 내경부를 통하여 끼워 위치시켰으며, 판(8')(8")의 양측 단부에는 연결공(8'b)(8"b), (8'c)(8"c)을 형성하되 연결공(8"b)(8'c)은 캠레버(3)와 핀치롤러암(5)에 고정된 연결핀(3b)(5a)이 긴밀하게 끼워지도록 형성되고 연결공(8'b)(8"c)은 연결핀(3b)(5a)이 헐겁게 끼워지도록 형성되어 있다.In the conventional pinch roller compaction apparatus, as shown in FIG. 1, the sliding pin 3a of the cam lever 3 having the fixed hinge point 2 is inserted into the cam groove 1a of the cam gear 1. , The pinch roller arm 5 having the pinch roller 4 adhered to one side end is fixed to the fixed hinge point 6, and the compression coil spring 7 is interposed between the cam lever 3 and the pinch roller arm 5. The pressing lever 8 is connected. Referring to FIG. 2, the pressing lever 8 is inserted into the middle of the two plates 8 'and 8 "overlapping the pressing lever 8 with an insertion hole 8'a (8" a). ) And a compression coil spring (7) is inserted into the insertion hole (8'a) (8 "a), and the compression coil spring (7) outside the plate (8 ') (8") to prevent separation For this purpose, the separation preventing pieces 9 and 9 ', which are bent at both ends, were inserted through the inner diameters of the springs 7, and the connecting holes 8'b are formed at both ends of the plates 8' and 8 ". 8 " b ", 8 " c, and 8 " c, wherein the connecting holes 8 " b " 3b) 5a is formed to be closely fitted, and the connection holes 8'b and 8 "c are formed so that the connection pins 3b and 5a are loosely fitted.
이와 같이 된 종래의 장치는 캠기어(1)가 제1도에서 J방향으로 회전하면 캠홈(1a)에 연결된 캠레버(3)가 힌지점(2)을 L 방향으로 움직이고 핀치롤러(4)는 힌지점(6)을 중심으로 M 방향으로 움직인다. 핀치롤러(4)가 캡스턴축(10)에 접하게 되면 캡홈(1a)은 계속 변위가 있어도 핀치롤러(4)는 더 이상 움직일 수 없게 되므로 캡스턴축(10)에 접하게 되면 캠홈(1a)은 계속 변위가 있어도 핀치롤러(4)는 더 이상 움직일 수 없게 되므로, 압착레버(8)의 압축 코일 스프링(7) 변위에 의하여 핀치롤러(4)에 압착력이 가하여 진다.In the conventional apparatus, the cam lever 3 connected to the cam groove 1a moves the hinge point 2 in the L direction when the cam gear 1 rotates in the J direction in FIG. 1, and the pinch roller 4 It moves in the M direction about the hinge point (6). When the pinch roller 4 is in contact with the capstan shaft 10, the cap groove 1a is displaced even if the cap groove 1a is continuously displaced. Therefore, when the pinch roller 4 is in contact with the capstan shaft 10, the cam groove 1a is continuously displaced. Since the pinch roller 4 can no longer be moved even if there is, a pressing force is applied to the pinch roller 4 by displacement of the compression coil spring 7 of the pressing lever 8.
그러나, 이와 같은 종래의 핀치롤러 압착장치는 2개의 판(8')(8") 사이에 압착 코일 스프링(7)을 삽입하고 이탈 방지편(9)(9')으로 압축 코일스프링(7)이 이탈을 방지하도록 한 복잡한 구성으로 되어 있으므로, 조립성이 저하될 뿐 아니라 고정 힌지점(2)(6)과 연결핀(3b)(5a)에 부품 탈락 방지를 위한 스토퍼링이 사용되는 등 사용된 부품수가 증가하는 문제점이 있었다.However, such a conventional pinch roller presser inserts the presser coil spring 7 between the two plates 8 'and 8 "and the compression coil spring 7 with the release preventing pieces 9 and 9'. Since it has a complicated configuration to prevent this separation, the assembly is not only deteriorated, but the stopper ring is used for the fixing hinge points 2, 6 and the connection pins 3b, 5a to prevent the component from falling out. There was a problem that the number of parts to be increased.
본 고안은 이와 같은 종래의 결함을 해소하기 위하여 안출한 것으로, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is devised to solve such a conventional defect, described in detail by the accompanying drawings as follows.

As shown in FIG. The pinch roller arm 27 in which the copper piece 24 'is inserted and connected, and the pinch roller 26 to be crimped on the capstan shaft 25 is fixed to the fixed hinge 28, and the pinch roller arm 27 And the cam lever 24 is connected to the pressing lever 29, the connecting pin (30a) fixed to the rear end of the pinch roller arm 27 is inserted and fixed to the stopper ring (32a) A long hole 31b having an insertion part 31b 'and an operating part 31b "is formed at the inner side of the lower lever 31 of the crimp lever 29 drilled at this end, and the long hole 31c and the engaging piece at the rear end thereof. 31d is bent and inserted into the front end hole 31b of the lower lever 31, and the end pieces 33a and 31d of the upper and lower levers 33 and 31 are provided at both ends of the tension coil spring 28, respectively. To the rear end of the upper lever (33). While fixing the connecting pin 34 having the slope 34a and the recess 34b, a mold hook 24b is formed on one side of the insertion portion 24a formed on the cam lever 24, and the mold hook 24b is formed. A protrusion 24d having an inclined surface 24c is formed on the inner side thereof, and the connecting pin 34 at the rear end of the upper lever 33 is inserted and fixed to the insertion portion 24a.
이와 같이 된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention made as follows.
본 고안 압착레버(29)의 상,하측 레버(33)(31)는 연결핀(34)과 걸림편(33a)에 의하여 조립되어 있다. 조립시 즉, 상측레버(33)의 걸림편(33a)을 하측레버(31)의 장공(31b)에 끼울 때 걸림편(33a)의 폭 a2가 장공(31b)의 삽입부(31b') 폭 a1을 통해서 끼워지고 인장 코일 스프링(28)의 힘에 의하여 작동부(31b")에 오게 되면 걸림편(33)의 걸림턱(33b)의 폭 a2보다 작동부(31b")의 폭 a3가 작으므로 이탈되지 않고 작동부(31b")에 오게 되면 걸림편(33)의 걸림턱(33b)의 폭 a2보다 작동부(31b")의 폭 a3가 작으므로 이탈되지 않고 작동부(31b") 구간에서 작동된다.The upper and lower levers 33 and 31 of the present invention crimp lever 29 are assembled by a connecting pin 34 and a locking piece 33a. When assembling, that is, when the locking piece 33a of the upper lever 33 is inserted into the long hole 31b of the lower lever 31, the width a2 of the locking piece 33a is the width of the insertion portion 31b 'of the long hole 31b. When it is fitted through a1 and comes to the operating portion 31b "by the force of the tension coil spring 28, the width a3 of the operating portion 31b" is smaller than the width a2 of the locking projection 33b of the locking piece 33. Therefore, when it comes to the operating portion 31b "without being separated, the width a3 of the operating portion 31b" is smaller than the width a2 of the locking jaw 33b of the locking piece 33, so that it is not separated and the operating portion 31b "is not separated. Works on
제3도에서 캠기어(22)가 B방향으로 회전하면 캠레버(24)가 접동핀(24')에 의하여 고정보스(23)을 중심으로 C방향으로 움직인다. 그러면 연결핀(34)에 의하여 압착 레버(29)는 D 방향으로 움직이고 연결핀(30)에 의하여 핀치롤러암(27)은 힌지점(28)을 중심으로 F 방향으로 움직이며 핀치롤러(26)가 캡스턴축(25)에 접한 다음부터는 핀치롤러암은 움직이지 않고 캠기어(22)의 초과변위에 의하여 압착레버(29)의 스프링(28)이 인장되면서 압착력을 가하게 된다.In FIG. 3, when the cam gear 22 rotates in the B direction, the cam lever 24 moves in the C direction about the high information 23 by the sliding pin 24 ′. Then, the pressing lever 29 moves in the D direction by the connecting pin 34, and the pinch roller arm 27 moves in the F direction about the hinge point 28 by the connecting pin 30. After contacting the capstan shaft 25, the pinch roller arm does not move, and the spring 28 of the compression lever 29 is tensioned by the over displacement of the cam gear 22, thereby applying a pressing force.
이때 압착레버(29)의 상하측 레버(33)(31)의 상호 마찰을 극소화하기 위하여 하측 레버(31)의 상면에 돌기(31e)를 엠보싱 형성하여 상측레버(33)가 하측레버(31)와 접촉되는 부분 네곳에서 점접촉되게 하면 좋다.At this time, in order to minimize mutual friction between the upper and lower levers 33 and 31 of the crimping lever 29, the projections 31e are embossed on the upper surface of the lower lever 31, so that the upper lever 33 is the lower lever 31. It is good to make point contact at the four parts which contact with a.
이상에서 설명한 바와 같은 본 고안은 압착레버의 상하측 레버에 걸림편을 각각 일체로 형성시키어 인장 코일 스프링을 걸도록 한 구조로서 사용 부품수를 감소시키고 조립체화 함으로써 조립이 용이하게 하였으며 캠레버와 압착레버 연결에도 몰드 후크를 이용하여 간단 용이하게 할 수 있는 이점이 있다.As described above, the present invention has a structure in which the engaging pieces are integrally formed on the upper and lower levers of the crimping lever to hang the tension coil spring, thereby reducing the number of parts used and assembling to facilitate assembly. The lever connection also has the advantage that it can be easily made by using a mold hook.
