The protrusion 213 is fastened to the fastener 214 for fixing the housing 212 to the cable tray (not shown), the protrusion 217 rotatable support roller 217 for stably supporting the wire 150 To be fixed.
하우징(212)의 내부 공간에는 작동실린더(455)를 장착한다. 이러한 작동실린더(455)는 공압에 의해 동작되는 것으로, 피스톤 로드(456)는 길이 방향으로 왕복 운동한다. 이러한 작동실린더(455)의 상면 일측에는 파지수단(300)을 고정한다. 작동실린더(455)의 상면에는 양측에 수직으로 지지바(341)를 고정하고, 지지바(341) 사이의 하부에는 전선(150)이 안정되게 안착되도록 원호면(342)을 형성한다.An operation cylinder 455 is mounted in the inner space of the housing 212.

도 13 및 도 14를 참조하여 본 발명의 바람직한 실시 예에 따른 전선 포설용 그리퍼의 작동방법을 상세하게 설명한다.13 and 14 will be described in detail the operation method of the gripper for wire laying according to a preferred embodiment of the present invention.
도 13 및 도 14에 도시된 바와 같이, 하우징(212)에는 작동실린더(455)가 장착된 상태로 케이블 트레이(미도시) 상에 고정된다. 이러한 하우징(212)의 고정은 돌출부(213)가 케이블 트레이의 가로대(미도시)에 올려지고, 가로대 및 돌출부(213)에 고정구(214)를 체결함으로써 고정된다. 즉, 하우징(212)은 케이블 트레이 상에 이동되지 않도록 고정된다.As shown in FIGS. 13 and 14, the housing 212 is fixed on a cable tray (not shown) with an operation cylinder 455 mounted thereto. Fixing of the housing 212 is a protrusion 213 is mounted on the crossbar (not shown) of the cable tray, and is fixed by fastening the fastener 214 to the crossbar and the protrusion 213. That is, the housing 212 is fixed so as not to move on the cable tray.
아울러 케이블 트레이 상에는 전선 포설용 그리퍼가 일정한 간격으로 다수개 고정되며, 전선(150)을 수평으로 이동시키는데 적용되는 것이 바람직하다.In addition, a plurality of grippers for wire laying are fixed at regular intervals on the cable tray, and is preferably applied to move the wire 150 horizontally.
아울러 파지수단(300)에는 이동시키고자 하는 전선(150)을 끼워 넣게 된다. 이러한 전선(150)은 원호면(342)과 마찰슈(343) 사이에 끼워진다.In addition, the gripping means 300 is inserted into the wire 150 to be moved. The wire 150 is sandwiched between the arc surface 342 and the friction shoe 343.
이와 같이 전선(150)은 파지수단(300)에 끼워진 상태에서 그리퍼에 설치된 작동실린더(455)가 제어신호에 따라 작동하게 된다.As such, the wire 150 is operated by the operation cylinder 455 installed in the gripper in a state of being fitted to the gripping means 300 according to the control signal.
도 13에 도시된 바와 같이, 작동실린더(455)가 도면상 좌측 방향으로 전진하게 되면, 작동실린더(455)에 고정되어 있는 파지수단(300) 또한 피스톤 로드(456)와 동일한 방향으로 이동하게 된다. 작동실린더(455)의 전진으로 지지바(341)는 작동실린더(455)와 동일한 방향으로 이동되고, 전선(150)이 압박된 마찰슈(343)의 마찰면(344)은 전선(150)을 일정한 압력으로 압박되도록 작동실린더(455)의 이동 방향과 반대 방향으로 회전된다. As shown in FIG. 13, when the operation cylinder 455 moves forward in the left direction in the drawing, the holding means 300 fixed to the operation cylinder 455 also moves in the same direction as the piston rod 456. . The support bar 341 moves in the same direction as the operation cylinder 455 as the working cylinder 455 moves forward, and the friction surface 344 of the friction shoe 343 to which the electric wire 150 is pressed moves the electric wire 150. It is rotated in a direction opposite to the moving direction of the operation cylinder 455 to be pressed at a constant pressure.
이때 마찰슈(343)는 전선(150)을 강하게 압박할 수 있도록 소정의 각도로만 회전된다. 이렇게 원호면(342)과 마찰슈(343)에 의해 전선(150)은 압박된 상태를 유지하게 된다. 이와 같이 전선(150)은 마찰슈(343)의 회전으로 원호면(342)과 마찰면(344) 사이에 압박된 상태에서 작동실린더(455)의 이동 방향과 동일한 방향으로 이동된다.At this time, the friction shoe 343 is rotated only at a predetermined angle so as to strongly press the wire 150. Thus, the wire 150 is maintained in a pressed state by the arc surface 342 and the friction shoe 343. In this way, the electric wire 150 is moved in the same direction as the movement direction of the operation cylinder 455 in a state in which the electric wire 150 is pressed between the arc surface 342 and the friction surface 344 by the rotation of the friction shoe 343.
한편 작동실린더(455)가 후진하는 경우, 마찰슈(343)는 지지바(341)에 편심되게 고정되어 있으므로, 마찰슈(343)는 역회전이 이루어진다. 이때 마찰슈(343)는 마찰면(344)이 전선(150)을 압박하고 있던 상태에서 역회전 되어 전선(150)과 느슨한 상태를 유지하게 된다.On the other hand, when the operation cylinder 455 is reversed, since the friction shoe 343 is fixed to the support bar 341 eccentrically, the friction shoe 343 is a reverse rotation. At this time, the friction shoe 343 is reversely rotated in a state where the friction surface 344 is pressing the wire 150 to maintain a loose state with the wire 150.
즉, 마찰슈(343)는 역회전할 때 단순히 전선(150)과 맞닿은 상태에서 소정의 각도만큼 회전이 이루어질 뿐 마찰에 의해 전선(150)을 가압하지 않게 되고, 이에 작동실린더(455)는 전선(150)을 이동시키지 않으면서 작동실린더(455)만 후진된다.That is, the friction shoe 343 is simply rotated by a predetermined angle in a state of being in contact with the wire 150 at the time of reverse rotation, so that the friction shoe 343 does not press the wire 150 by friction, and thus the operation cylinder 455 is a wire Only the working cylinder 455 is retracted without moving the 150.
이와 같이 작동실린더(455)가 전진할 때 전선(150)은 일 방향(이동시키고자 하는 방향)으로 이동되고, 작동실린더(455)가 후진할 때 전선(150)은 제자리에 있게 된다. 따라서 전선(150)은 작동실린더(455)의 전진 시에 마찰슈(343)에 의해 압박된 이후 작동실린더(455)에 의해 일정한 거리만큼 이동된다.As such, when the operation cylinder 455 moves forward, the wire 150 moves in one direction (the direction to be moved), and when the operation cylinder 455 moves backward, the wire 150 is in place. Therefore, the electric wire 150 is moved by the operation cylinder 455 by a predetermined distance after being pressed by the friction shoe 343 when the operation cylinder 455 advances.
이렇게 작동실린더(455)의 전진에 의해 전선(150)은 이동시키고자 하는 방향으로 일정 거리(실린더의 전진 거리)만큼 반복적으로 이동되어 전선(150)을 포설할 수 있게 된다.In this way, the electric wire 150 is repeatedly moved by a predetermined distance (advancing distance of the cylinder) in the direction to move by the advance of the operation cylinder 455 to be able to install the wire 150.
도 15 및 도 16에 도시된 바와 같이, 본 발명에 따른 케이블 그리퍼는 왕복운동을 하는 동력부에 설치되어 왕복운동시 자동으로 전선(150)이 진행될 수 있도록 한다. 특히, 원웨이 베어링(335)과 롤러를 사용하여 그리퍼가 초기 구동위치로 복귀시에 전선(150)과 그리퍼와의 마찰력을 줄이도록 구성된다.As shown in Figure 15 and 16, the cable gripper according to the present invention is installed in the power unit for reciprocating motion so that the wire 150 can automatically proceed during the reciprocating motion. In particular, the one-way bearing 335 and the roller are used to reduce the friction between the wire 150 and the gripper when the gripper returns to the initial drive position.
또한, 병렬로 혹은 직렬로 그리퍼를 설치할 수 있도록 하여 이송시 개별 그리퍼의 원웨이 베어링(335)에 걸리는 토크를 줄여 소형화를 이룰 수 있게 된다.In addition, by allowing the grippers to be installed in parallel or in series, it is possible to reduce the torque applied to the one-way bearing 335 of the individual grippers during transportation to achieve miniaturization.
뿐만 아니라, 한쪽 방향으로만 전선(150)이 진행되기 때문에 수직 전선포설시 전선(150)이 뒤로 밀려나는 현상이 없으며, 진행방향으로는 저항이 없어 전선의 선단에 윈치를 사용하게 될 경우라도 전선 가이드 형태로 사용할 수도 있다.In addition, there is no phenomenon that the wire 150 is pushed backward when the vertical wire is laid because the wire 150 proceeds only in one direction, and there is no resistance in the moving direction, even when the winch is used at the tip of the wire. It can also be used as a guide.
아울러, 그리퍼를 가이드하고 있는 결속구(352)의 경우 수갑의 구조처럼 후킹(Hooking)할 수 있는 구조로 제작하게 되면 전선(150)에 가해지는 압력을 조정할 수 있고, 전선의 굵기에 상관없이 사용할 수 있다.In addition, in the case of the binding hole 352 that guides the gripper, if the structure is made of a hooking structure, the pressure applied to the wire 150 can be adjusted and used regardless of the thickness of the wire. Can be.
또한, 전선(150)의 사이즈에 따라 그리퍼의 크기와 개수는 조정될 수 있으며, 약간의 변형을 통하여 수동 전선포설 작업시에도 효과적으로 사용할 수 있음은 물론이다. 바람직하게, 상기 그리퍼(310)는 상기 전선(150)의 둘레를 따라 120ㅀ간격을 두고 3개 설치될 수 있다. 상기 그리퍼(310)는 여러가지 형상이 있을 수 있지만, 안정감 측면에서 도시와 같은 'H' 형상으로 형성됨이 바람직하다.In addition, the size and number of grippers can be adjusted according to the size of the wire 150, it can be used effectively during manual wire laying work through a slight deformation. Preferably, three grippers 310 may be installed at 120 ㅀ intervals along the circumference of the wire 150. The gripper 310 may have various shapes, but is preferably formed in the 'H' shape as shown in the sense of stability.
다만, 실시예를 통해 'H' 형상으로 상기 그리퍼(310)를 도시했다고 해서 권리범위가 그 형상으로 한정되는 것은 아니며, H 형상으로 형성된 상기 그리퍼(310)에 상기 롤축(356)과 롤러(354)는 상기 그리퍼(310) 당 2개씩 대칭되게 구비될 수 있다.However, just by showing the gripper 310 in the 'H' shape through the embodiment is not limited to the shape of the right, the roll shaft 356 and the roller 354 to the gripper 310 formed in the H shape ) May be provided symmetrically two per gripper 310.
그리고, 상기 그리퍼(310)의 일부에는 롤축(356)이 끼워지고, 상기 롤축(356)에는 롤러(354)가 회전가능하게 설치된다. 이 경우, 상기 롤러(354)는 상기 그리퍼(310) 보다 더 큰 직경을 갖도록 하여 상기 그리퍼(310)가 전선(150)에 설치되었을 때 상기 전선(150)과 접촉되는 부분은 그리퍼(310)가 아닌 롤러(354)가 될 수 있도록 하여야 한다.In addition, a roll shaft 356 is fitted to a part of the gripper 310, and a roller 354 is rotatably installed on the roll shaft 356. In this case, the roller 354 has a larger diameter than the gripper 310 so that the gripper 310 is in contact with the wire 150 when the gripper 310 is installed on the wire 150. It should be able to be a roller 354 rather than.
또한, 도시된 예에서는 2개 한 조의 롤러(354)가 6개 설치되어 있고, 그리퍼(310)가 3개 설치되어 있는 것으로 설명하고 있으나, 이는 바람직한 실시예에 불과할 뿐이며 전선(150)의 직경에 따라 다른 갯수로 설치될 수 있음은 물론이며, 본 발명 기술적 사상의 범위 내에서 얼마든지 변형할 수 있다.In addition, in the illustrated example, six sets of two rollers 354 are provided, and three grippers 310 are described. However, this is only a preferred embodiment, and the diameter of the wire 150 is not limited thereto. Of course, it can be installed in a different number, of course, it can be modified as much within the scope of the invention.
뿐만 아니라, 상기 그리퍼(310)에는 원웨이 베어링(335)이 설치되는데, 상기 원웨이 베어링(335)은 상기 롤축(356)의 회전방향을 제어하여 일방향으로만 회전되게 하고, 그 반대방향으로는 회전을 정지시키도록 구성된 공지의 유닛이다.In addition, the gripper 310 is provided with a one-way bearing 335, the one-way bearing 335 is rotated in one direction by controlling the rotation direction of the roll shaft 356, the opposite direction It is a known unit configured to stop the rotation.
즉, 원웨이 베어링(335)이란 분리된 두 개의 축을 매개하여 하나의 축을 만들 때 양 회전방향중 하나의 회전방향에는 축에 물려 축과 함께 회전하지만, 그 반대 회전방향으로 축이 회전할 때에는 축만 회전하도록 동력을 전달하는 공지된 일방향으로만 회전되는 베어링을 말한다. 원웨이 베어링(335)은 구조가 널리 알려진 공지된 유닛이므로 본 발명에서는 굳이 설명하지 않으며, 도시된 예에서도 그리퍼(310)의 일부를 구성하고 있는 외관을 지칭하여 원웨이 베어링(335)이라고 설명하기로 한다.That is, the one-way bearing 335 is rotated together with the shaft in the rotation direction of one of the two rotation directions when one axis is made through two separate shafts, but only when the shaft rotates in the opposite rotation direction It refers to a bearing that rotates only in one known direction that transmits power to rotate. Since the one-way bearing 335 is a well-known unit having a well-known structure, the one-way bearing 335 is not necessarily described in the present invention. Shall be.
그리고, 상기 그리퍼(310)는 고정링(350)에 끼워져 고정링(350)을 따라 고정링(350)의 반경방향으로 움직일 수 있도록 구성되며, 상기 고정링(350)의 일부는 절개되어 있고, 그 절개된 부분에는 앞서 설명한 수갑형 결속구조를 갖는 결속구(352)가 설치된다.In addition, the gripper 310 is inserted into the fixing ring 350 to be configured to move in the radial direction of the fixing ring 350 along the fixing ring 350, a part of the fixing ring 350 is cut, The cut-out part is provided with a binding hole 352 having the shackle-type binding structure described above.
다시 말해, 상기 결속구(352)는 일종의 고정구로서, 그리퍼(310)의 절개된 양단에는 일정길이 고정후크(미도시)가 형성되고, 상기 결속구(352)의 양단 내경에는 라체트 기능, 즉 스프링에 의해 탄발되는 걸림후크(미도시)가 구비되어 상기 그리퍼(310)의 양단이 상기 결속구(352) 내부로 인입될 때는 후킹이 안되고, 빠져나가려고 할 때는 후킹되게 하여 결속을 이룰 수 있도록 하며, 해제시에는 별도의 노브를 두어 이 노브를 눌러 줌으로써 후킹 상태를 해제하여 빼낼 수 있다.In other words, the fastener 352 is a kind of fastener, and a fixed length hook (not shown) is formed at both ends of the gripper 310, and the inner diameter of both ends of the fastener 352 is defined. A hooking hook (not shown) provided by a spring is provided to prevent hooking when both ends of the gripper 310 are introduced into the binding hole 352, so that the hooking hook can be achieved by hooking when it exits. In case of release, it is possible to release the hooking state by pressing the knob by putting a separate knob.
이러한 구성으로 이루어진 본 발명에 따른 전선 그리퍼는 전선(150)이 진행되는 방향으로는 원웨이 베어링(335)이 작동하여 롤축(356)을 고정하기 때문에 롤러(354)가 회전하지 않게 된다. 이 경우에 롤러(354)와 전선(150) 간의 마찰이 극심하여 롤러(354)가 전선(150)을 잡고 이동할 수 있게 된다. 반면에, 상기 전선(150)의 진행 방향의 반대로 본 발명 그리퍼가 움직일 때에는 원웨이 베어링(335)이 작동하지 않아 롤축(356)을 고정하지 않기 때문에 롤러(354)가 원활하게 회전하면서 전선(150) 표면과 구름 접촉하게 된다. 이 경우에는 그리퍼만 이동시킬 수 있게 된다.In the wire gripper according to the present invention having such a configuration, the roller 354 does not rotate because the one-way bearing 335 operates to fix the roll shaft 356 in the direction in which the wire 150 proceeds. In this case, the friction between the roller 354 and the wire 150 is so severe that the roller 354 can move and hold the wire 150. On the other hand, since the one-way bearing 335 does not operate and does not fix the roll shaft 356 when the gripper of the present invention moves in the opposite direction of the traveling direction of the wire 150, the roller 354 smoothly rotates the wire 150. ) The surface is in contact with the cloud. In this case, only the gripper can be moved.
도 17에서, 본 발명은 운동체(210) 및 제1,2그리퍼카(311,312)에 원웨이 베어링(335)이 설치되어 일방향으로는 회전되고, 반대방향으로는 회전되지 않도록 구성된다. 상기 운동체(210)는 상기 전선(150)의 둘레 중 하부에 위치되도록 구성될 수 있다. 상기 운동체(210)의 양단에는 그리퍼카 가이드링(380)을 구성하는 제1가이드링(382)과 제2가이드링(384)이 각각 회전가능하게 힌지고정된다.In FIG. 17, the present invention is configured such that the one-way bearing 335 is installed on the moving body 210 and the first and second gripper cars 311 and 312 to rotate in one direction and not rotate in the opposite direction. The moving body 210 may be configured to be located at a lower portion of the circumference of the wire 150. The first guide ring 382 and the second guide ring 384 constituting the gripper car guide ring 380 are rotatably hinged to both ends of the moving body 210, respectively.
즉, 상기 그리퍼카 가이드링(380)는 분할된 두 개의 제1,2가이드링(382,384)이 서로 조합되어 전선(150)을 감싸는 형태로 결속할 수 있으며, 이들이 조합되어 하나의 그리퍼카 가이드링(380)을 구성하게 된다.That is, the gripper car guide ring 380 may be combined in a form in which two divided first and second guide rings 382 and 384 are combined with each other to surround the electric wire 150. 380 is configured.
아울러, 상기 제1,2가이드링(382,384)의 서로 마주보는 단부에는 체결용 볼트(386)와 체결용 너트(387)가 구비되어 상호 체결됨으로써 상기 제1,2가이드링(382,384)이 상기 전선(150)의 외주면을 완전히 감싸면서 결속되도록 구성된다.In addition, the first and second guide rings 382 and 384 are provided with fastening bolts 386 and fastening nuts 387 at opposite ends of the first and second guide rings 382 and 384 so that the first and second guide rings 382 and 384 are connected to each other. It is configured to bind while completely surrounding the outer peripheral surface of (150).
이때, 상기 제1,2가이드링(382,384)의 마주보는 단부는 각각 길이방향에 대하여 수직하게 절곡된 후 서로 접촉되게 맞대어지며, 제1가이드링(382)의 수직단부에 는 대략 'U' 형상의 홈(389)이 형성되고, 상기 제2가이드링(384)의 수직단부에는 폭방향으로 끼워진 힌지축(388)이 구비되며, 상기 힌지축(388)에는 상기 체결용 볼트(386)가 수직하게 고정되어 일체를 이룬다.At this time, the opposite ends of the first and second guide rings 382 and 384 are bent vertically with respect to the longitudinal direction and then contacted with each other, and the vertical ends of the first guide rings 382 are approximately 'U' shaped. The groove 389 is formed, the vertical end of the second guide ring 384 is provided with a hinge shaft 388 fitted in the width direction, the fastening bolt 386 is perpendicular to the hinge shaft 388 It is fixed to form a unity.
따라서, 상기 체결용 볼트(386)는 상기 힌지축(388)을 매개로 회전가능하게 구성되며, 상기 홈(389)에 끼워진 후 체결용 너트(387)가 제1가이드링(382)의 수직단부 전방으로 돌출된 상기 체결용 볼트(386)에 체결되고, 조여져 제1가이드링(382)의 수직단부 전면에 밀착되면 상기 그리퍼카 가이드링(380)은 전선(150)의 외주면에 견실 안정적으로 결착되게 된다.Therefore, the fastening bolt 386 is configured to be rotatable through the hinge shaft 388, and the fastening nut 387 is inserted into the groove 389 and the vertical end of the first guide ring 382. When the gripper car guide ring 380 is fastened to the fastening bolt 386 protruding forward and tightly adhered to the front surface of the vertical end of the first guide ring 382, the gripper car guide ring 380 is firmly and securely attached to the outer circumferential surface of the wire 150. Will be.
한편, 상기 제1,2가이드링(382,384)의 내주면 일부에는 그 폭방향으로 경사면이 형성되는데, 상기 경사면은 도 20에 모식적으로 표현된 바와 같이, 전선(150)이 진행되는 방향으로 하향돌출되게 형성되어 후술되는 연결부(385)도 그와 대응되게 경사 형성되게 함으로써 진행방향으로는 쐐기형태로 맞물려 더 이상 움직이지 못하도록 하고, 진행방향 반대쪽으로는 움직일 수 있도록 구성된다.On the other hand, a part of the inner circumferential surface of the first and second guide rings (382, 384) is formed with an inclined surface in the width direction, the inclined surface is projected downward in the direction in which the wire 150 proceeds, as shown schematically in FIG. The connection portion 385 to be described later is also formed to be inclined to correspond to it so as to be engaged in a wedge shape in the direction of travel so that it can no longer move and move in the direction opposite to the direction of travel.
즉, 상기 제1,2가이드링(382,384)의 안쪽에는 상기 전선(150)의 외주면과 접촉되는 롤러(354)를 구비한 원웨이 베어링(335)이 설치된 제1,2그리퍼카(311,312)가 위치되는데, 상기 제1,2그리퍼카(311,312)는 전선(150)의 반경방향으로 간격을 두고 배치되며, 대략 'H' 형상을 갖고, 평행한 양측에 상기 원웨이 베어링(335)이 설치되며, 평행한 양측을 서로 수직하게 연결하는 연결부(385)는 상기 경사면에 끼워진다.That is, the first and second gripper cars 311 and 312 having one-way bearings 335 having rollers 354 contacting the outer circumferential surface of the electric wire 150 are installed inside the first and second guide rings 382 and 384. The first and second gripper cars 311 and 312 are disposed at intervals in a radial direction of the wire 150, have a substantially 'H' shape, and the one-way bearings 335 are installed on both sides in parallel. The connecting portion 385 connecting the two parallel sides perpendicularly to each other is fitted to the inclined surface.
이때, 상기 연결부(385)의 형상은 도 20과 같이 경사면에 대응되게 경사형성된다. 그리고, 상기 롤러(354)는 상기 원웨이 베어링(335)의 길이 중간에 설치되며, 전선(150)의 외주면과 유일하게 구름접촉한다. 특히, 상기 원웨이 베어링(335)은 상기 제1,2그리퍼카(311,312)의 양단에 각각 설치되어 2개 한 쌍이 한조를 이루도록 구성됨이 더욱 바람직하다.At this time, the shape of the connecting portion 385 is inclined to correspond to the inclined surface as shown in FIG. In addition, the roller 354 is installed in the middle of the length of the one-way bearing 335, and is only in contact with the outer circumferential surface of the wire 150. Particularly, the one-way bearing 335 is installed at both ends of the first and second gripper cars 311 and 312, respectively, so that the two pairs are configured to form a pair.
이와 같이, 본 발명은 그리퍼카 가이드링(380)과 제1,2그리퍼카(311,312)가 서로 쐐기 구조로 맞물리게 구성함으로써 전선(150)을 견인하는 방향으로는 쐐기되어 외경 오차가 있더라도 완전하게 꽉 맞물린 상태를 유지하면서 견인하기 때문에 견인력의 손실이 없고, 파지력이 비약적으로 향상되며, 반대로 움직일 때는 쐐기 구조가 풀리기 때문에 원활하게 후퇴할 수 있어 사용상 편의성은 물론 작업효율성, 외경에 맞게 자동조절되는 기능 등이 현저히 개선된 것임을 알 수 있다.As such, the present invention constitutes the gripper car guide ring 380 and the first and second gripper cars 311 and 312 engaged with each other in a wedge structure so that the gripper car guide ring 380 and the first and second gripper cars 311 and 312 are wedge in the direction of towing the electric wire 150 and are completely tight even if there is an outer diameter error. There is no loss of traction force because the towing is maintained while being engaged, and the grip force is remarkably improved, and when moving, the wedge structure is loosened so that it can be retracted smoothly. It can be seen that this is a marked improvement.
이러한 구성으로 이루어진 본 발명에 따른 전선 그리퍼는 전선(150)의 외경이 제작오차로 인해 길이에 따라 다소 차이가 있더라도 제1,2그리퍼카(311,312)의 연결부(385)는 전선(150)이 이동하는 방향으로 딸려 가면서 미끌려 내려가도록 구성된다. 결국 제1,2가이드링(382,384)의 경사면을 따라 이동하면서 쐐기 형태로 맞물리므로 파지력이 급상승하게 되고, 이것은 손실없이 전선(150)을 견인할 수 있도록 하여 준다.In the wire gripper according to the present invention having such a configuration, even if the outer diameter of the wire 150 is slightly different depending on the length due to manufacturing errors, the connection portion 385 of the first and second gripper cars 311 and 312 moves the wire 150. It is configured to slide down in the direction of the direction. As a result, the gripping force is rapidly increased since the first and second guide rings 382 and 384 move along the inclined surfaces and engage in a wedge shape, which allows the wire 150 to be pulled without loss.
그러므로, 기존처럼 파지력 감소나 혹은 외경이 커 꽉 맞물리면서 견인 불량이 야기되지 않는데, 그 이유는 외경이 커질 경우에는 경사면을 타고 이동하는 양이 작아지면서 전선(150)의 외경에 맞게 자동 조절되기 때문이다.Therefore, the grip force decreases or the outer diameter is too large, and the traction failure is not caused, as the conventional, because the outer diameter is large, because the amount of movement along the slope is smaller and automatically adjusted to the outer diameter of the wire 150. .
도 21 내지 도 24에서, 본 발명에 따른 그리퍼 장치는 일종의 고정판인 하우징(212)과, 상기 하우징(212)의 상면에 길이방향으로 돌출 형성된 가이드레일(230)과, 상기 가이드레일(230)을 따라 슬라이딩되는 작동플레이트(232)와, 상기 하우징(212)의 선단에 고정되고 일정 스트로크를 갖고 직선 왕복운동하는 운동체(210)와, 상기 운동체(210)의 운동력을 상기 작동플레이트(232)에 전달하여 상기 작동플레이트(232)가 운동체(210)의 스트로크 범위내에서 직선 왕복운동하도록 안내하는 연결브라켓(234)을 포함하여 구성된다.21 to 24, the gripper device according to the present invention includes a housing 212 which is a kind of fixed plate, a guide rail 230 protruding in the longitudinal direction on the upper surface of the housing 212, and the guide rail 230. The operating plate 232 which is slid along, the moving body 210 fixed to the front end of the housing 212 and linearly reciprocating with a predetermined stroke, and transfers the kinetic force of the moving body 210 to the operating plate 232 The operation plate 232 is configured to include a connecting bracket 234 for guiding the linear reciprocating motion within the stroke range of the moving body 210.
여기에서, 상기 가이드레일(230)은 상기 작동플레이트(232)가 쉽게 분리 이탈되지 않도록 하방으로 경사지면서 상방에 비해 폭이 좁아진 쐐기 형태를 갖도록 형성함이 바람직하다.Here, the guide rail 230 is preferably formed to have a wedge shape narrower than the upper side while inclined downward so that the operation plate 232 is not easily separated and separated.
그리고, 상기 운동체(210)에는 동력변화에 따라 일정 스트로크 내에서 왕복운동하는 구동로드(233)가 구비되고, 상기 구동로드(233)의 단부에는 연결브라켓(234)이 고정되며, 연결브라켓(234)의 다른 일부에는 상기 작동플레이트(232)의 일측이 고정된다.In addition, the moving body 210 is provided with a driving rod 233 to reciprocate within a predetermined stroke in accordance with the power change, the connection bracket 234 is fixed to the end of the driving rod 233, the connection bracket 234 One side of the operation plate 232 is fixed to the other part of).
한편, 상기 작동플레이트(232)의 선단 상면에 고정되어 상기 전선(150)을 그립핑하여 이동시키는 파지수단(300)이 구비된다. 상기 파지수단(300)은 상기 스트로크 범위내에서 상기 작동플레이트(232)가 전,후진할 때 전진시에만 그립핑하여 전선(150)을 이송시키고, 후진할 때는 그립핑을 해제하여 이송된 전선(150)이 후퇴되지 않도록 동작한다. 때문에, 아주 협소한 공간 상에서도 전선 포설작업을 용이하게 수행할 수 있게 된다.On the other hand, the holding means 300 is fixed to the upper end surface of the operation plate 232 to grip and move the wire 150 is provided. The gripping means 300 transfers the wire 150 by gripping only when the operation plate 232 moves forward and backward within the stroke range, and releases the gripping when moving backward. 150) does not retract. This makes it easy to install the wires even in a very narrow space.
이를 위해, 상기 파지수단(300)은 상기 작동플레이트(232)의 선단 상면에 고정된 베이스(211)와, 상기 베이스(211)의 상면 양측에 돌출되고 상면은 호형상으로 요입형성되며 일측에는 링브라켓(362)이 형성된 지지블럭(361)과, 상기 지지블럭(361)의 호형상 요입부에 돌출된 스토퍼(225)와, 상기 지지블럭(361)의 호형상 요입부에 안착되어 회동가능하게 구비되는 한쌍의 회동링(364)을 갖는 호형상의 그립링크(363)와, 상기 회동링(364)에 형성되고 상기 스토퍼(225)가 삽탈되는 장공형 스토퍼홈(365)과, 상기 링브라켓(362) 및 회동링(364)을 관통하여 회전축 역할을 하면서 일단에는 상기 그립링크(363)의 일부가 끼워지는 홀더(367)를 구비한 링크고정핀(366)을 포함하여 구성된다.To this end, the holding means 300 is a base 211 fixed to the top surface of the front end of the operation plate 232, protrudes on both sides of the upper surface of the base 211 and the upper surface is formed in a concave shape arc and one side ring A support block 361 having a bracket 362 formed therein, a stopper 225 protruding from the arc-shaped recess of the support block 361, and a rotatable recess of the support block 361 are rotatably mounted. An arc-shaped grip link 363 having a pair of rotating rings 364 provided therein, a long stopper groove 365 formed in the rotating ring 364 and in which the stopper 225 is removed, and the ring bracket It comprises a link fixing pin (366) having a holder (367) is inserted into a portion of the grip link (363) at one end through the 362 and the rotating ring (364) to serve as a rotation axis.
따라서, 상기 회동링(364)은 지지블럭(361)의 호형상 요입부에 안착된 상태에서 상기 링크고정핀(366)을 회전축으로 하여 회동가능하게 유지되며, 또한 상기 장공형 스토퍼홈(365)은 그립링크(363)가 수직하게 세워졌을 때, 다시 말해 그립링크(363)가 시계방향으로 회전할 때에는 수직상태를 유지함과 동시에 상기 스토퍼(225)가 스토퍼홈(365)의 전단에 걸리도록 하여 스토핑 기능을 수행하고 그립링크(363)가 반시계방향으로 회동할 때에는 스토퍼홈(365) 자체가 약간 장공형이어서 스토퍼홈(365)의 후단과 유격이 있으므로 스토핑없이, 즉 걸림없이 원활히 회전될 수 있도록 안내하게 된다.Accordingly, the pivot ring 364 is rotatably held by the link fixing pin 366 as a rotation axis in a state in which the pivot ring 364 is seated on the arc-shaped recess of the support block 361. When the grip link 363 is erected vertically, that is, when the grip link 363 rotates in the clockwise direction, the stopper 225 is caught by the front end of the stopper groove 365. When the stopper function and the grip link 363 rotates in the counterclockwise direction, the stopper groove 365 itself is slightly long, so there is play with the rear end of the stopper groove 365, so that it stops smoothly, that is, without jamming. You will be guided to become.
때문에, 상기 그립링크(363)는 엑츄에이터가 전진하게 되면 작동플레이트(232)도 전진하게 되는데, 이때 전선(150)은 그립링크(363)에 끼워져 있고 전선(150)의 하단은 상기 링크고정핀(366)과 선접촉하고 있는 상태이므로 상호 마찰에 의해 링크고정핀(366)은 반시계방향으로 회전하게 된다.Therefore, the grip link 363 is to advance the operation plate 232 when the actuator is advanced, wherein the wire 150 is fitted to the grip link 363 and the lower end of the wire 150 is the link fixing pin ( 366), the link fixing pin 366 rotates counterclockwise due to mutual friction.
그러면, 상기 링크고정핀(366)의 홀더(367)가 그립링크(363)를 맞물고 있으므로 결국 그립링크(363)도 반시계방향으로 회전되면서 그립링크(363)가 비스듬하게 뒤로 젖혀지면서 전선(150)을 맞물게 되고, 그 상태에서 전진되므로 전선(150)을 당겨가게 된다. 이에 따라, 전선(150)은 스트로크 만큼 전진한다.Then, since the holder 367 of the link fixing pin 366 engages the grip link 363, the grip link 363 is also rotated counterclockwise, and the grip link 363 is tilted backwards. 150 is engaged, and the wire 150 is pulled because it is advanced in the state. Accordingly, the electric wire 150 is advanced by the stroke.
반면에, 엑츄에이터가 원래 위치로 돌아가기 위해 후진하게 되면 후진이 시작됨과 동시에 링크고정핀(366)은 시계방향으로 회전하게 되고, 이에 따라 홀딩된 그립링크(363)도 시계방향으로 회전하면서 똑바로 수직하게 세워진다. 그런데, 이때 세워짐과 동시에 지지블럭(361) 상의 스토퍼(225)는 회동링(364)의 장공형 스토퍼홈(365)에 끼워지면서 스토퍼홈(365)의 전단에 걸림되므로 더 이상 회전하지 못하게 된다.On the other hand, if the actuator is retracted to return to the original position, the reverse starts and at the same time, the link retaining pin 366 rotates clockwise, so that the grip grip 363 also rotates clockwise and vertically. It is built to be. However, at this time, the stopper 225 on the support block 361 is fitted to the long stopper groove 365 of the rotation ring 364 and is prevented from rotating any further because it is caught by the front end of the stopper groove 365.
따라서, 링크고정핀(366)은 전선(150)의 하단과 선접촉된 상태에서 슬립되면서 엑츄에이터의 홈포지션으로 복귀되고, 이때 그립링크(363)는 세워진 상태, 다시 말해 전선(150)과 간섭없는 상태를 유지하면서 그대로 복귀되기 때문에 전선(150)은 이미 이동된 상태에서 그대로 있고 그립링크(363)만 후퇴하여 이동하게 된다. 이어, 다시 엑츄에이터가 전진하면 상술한 과정을 그대로 반복하면서 전선(150)을 당겨 가고, 반대로 복귀 후 다시 당겨가게 된다.Accordingly, the link fixing pin 366 is returned to the home position of the actuator while slipping in the line contact with the lower end of the wire 150, wherein the grip link 363 is in an up state, that is, without interference with the wire 150 Since the wire 150 remains as it is while it is still in the state, only the grip link 363 retreats and moves. Subsequently, when the actuator moves forward again, the wire 150 is pulled while repeating the above-described process as it is, and after the return, the actuator is pulled again.
이와 같은 과정이 반복적으로 수차례 일어나면 전선(150)을 원활하게 이동시킬 수 있어 쉽고 편리하게 포설할 수 있게 된다.If this process occurs several times repeatedly, the wire 150 can be moved smoothly and can be installed easily and conveniently.
