본 발명은 자력흡착기(리프터 마그네트)의 흡착자력 자동 개폐장치에 관한 것이다.The present invention relates to an automatic magnetic suction device of the magnetic suction device (lifter magnet).

종래의 자력 흡착기는 이의 자력을 개폐할시는 핸들을 수동으로 조작하도록 하고 있는 관계로 철판이나 금형과 같은 증량체를 호이스트와 같은 자동이송장치를 이용하여 원격조정으로 이동시키는 작업을 할 때는 사용 불가능한 결점이 있었던 것이다.Conventional magnetic adsorbers require manual operation of the handles to open and close their magnetic forces. Therefore, they cannot be used to move extenders such as steel plates or molds by remote control using automatic transfer devices such as hoists. There was a flaw.

본 발명은 이상의 문제점을 해결하고자 발명한 것으로 이의 고안 요지는 자력 흡착기 몸체의 상부에 입설된 좌우 안내간에는 상면에 걸고리가 있는 증량체가 끼움 안내되게하고 이 증량체의 일측에 형성된 장공내에는 자력 개폐 핸들을 조작시키는 링크가 핀에 의해 끼움되어 승강되게하고 증량체의 앞측좌우에는 자력 흡착기 몸체의 좌우측에 설치된 걸림핀에 걸림되는 걸림턱을 가진 자동스토파가 축핀에 의해 설치되어 연결간으로 연결하되 일측 가동스토파와 전기한 안내장공과의 사이에는 3각 형상의 캠을 가진 래칫휘일을 설치하고 이 래칫휘일은 스프링에 의해 탄설된 포올이동핀의 회전포올에 의해 회동되게하므로서 걸고리에 호이스트를 연결하여 리모콘의 원격조정으로 증량체를 위로 들어올리면 링크와 연결된 핸들이 회동함에 따라 흡착 자력은 ON상태가 되어 물체를 흡착하여 운반할 수 있게되고 흡착된 물체를 일정지점에 옮긴 후 자력 흡착기를 대판위에 놓으면 이때에는 증량체는 자중에 의해 하강함에 따라 링크도 함께 하강되면서 핸들을 역회전시켜 자력을 OFF시킴과 동시 래칫휘일이 1/6바퀴 회전되면서 캠이 수직면을 이룸에 따라 가동스토파는 내향이 동하여 이의 하단 걸림턱이 자력 흡착기의 턱에 걸림될 수 있게 된다.The present invention has been invented to solve the above problems, and the subject matter of the present invention is that the extender having a hook on the upper surface is inserted between the left and right guides placed on the upper side of the magnetic adsorber body, and the magnetic opening and closing handle is formed in the long hole formed at one side of the extender. The link for manipulating the fitting is lifted by the pins and the front and rear of the extender is provided with an automatic stopper having a locking jaw that is caught by the locking pins installed on the left and right sides of the magnetic adsorber body and connected by the shaft pins. A ratchet wheel with a triangular cam is installed between the movable stopper and the guide guide, and the ratchet wheel is pivoted by the rotating pole of the pole moving pin installed by the spring, and the hoist is connected to the hook. Lifting the extender up remotely allows adsorption as the handle connected to the link rotates. The magnetic force is turned on so that the object can be adsorbed and transported, and after moving the adsorbed object to a certain point, the magnetic adsorber is placed on a large plate. By turning off the magnetic force and simultaneously the ratchet wheel is rotated 1/6 turn, the cam moves in the vertical plane, so the movable stopper moves inward and the lower end of the jaw can be caught by the jaw of the magnetic adsorber.

다음으로 증량체를 다시한번 들어올리면 이때에는 증량체가 안내간을 따라 상승함에 따라 가동스토파의 걸림턱은 흡착기 몸체의 측면에 돌설된 걸림핀(1')에 걸림되어짐과 동시 링크(2)는 장공의 크기 범위내에서 약간 이동되나 이때 링크에 연결된 핸들은 제자리에 그대로 멈추고 있기 때문에 흡착기는 OFF된 상태가 된다.Next, when the extender is lifted once again, at this time, as the extender rises along the guide interval, the stopping jaw of the movable stop is caught by the catching pin 1 'protruding from the side of the adsorber body and the simultaneous link 2 is It moves slightly within the size of the long hole, but the adsorber is turned off because the handle connected to the link is still in place.

즉 이때에는 흡착기 자체만을 이동시킬 수 있게 한 것이다.In this case, only the adsorber itself can be moved.

이를 도면에 의거 상세히 설명하면 다음과 같다.This will be described in detail based on the drawings.

흡착기(1)의 상면에 좌우 안내간(11)을 입설하여 증량체(3)가 끼움안내되게하고 흡착기(1)의 축(1")일측에 끼움 설치된 핸들(2")에는 링크(2)의 일단이 핀에 의해 회동가능하게 연결되고 링크(2)의 타단에 기움된 핀(2')은 증량체(3)의 일측에 형성된 장공(3')에 끼움걸림되며 증량체(3)의 앞측에 형성된 절결부(3")에는 하단에 걸림턱(6")이 있는 가동스토파(6)의 상단이 핀(1")에 의해 회동가능하게 설치되고 가동스토파(6)의 내측 상부에 형성된 턱(6"')은 축핀(5")에 의해 회동 가능하게 설치된 래칫휘일(5)의 캠(4)과 접하게 하며 래칫휘일(5)의 턱(5')에 걸림되는 회전포올(8)은 포올이동핀(8')과 연결되어 있고 포올이동핀(8')은 스프링(10)을 개재한 상태에서 케이스(9)에 설치되어 있으며 전기한 래칫휘일(5)의 턱(5')에는 역회전 방지포올(7)이 걸림되어진 구조이다.The left and right guide bars 11 are installed on the upper surface of the adsorber 1 so that the extender 3 can be guided and the handle 2 " installed on one side of the shaft 1 " One end of the extender 3 is rotatably connected by a pin and the pin 2 'tilted at the other end of the link 2 is fitted into the long hole 3' formed at one side of the extender 3, In the cutout part 3 "formed at the front side, the upper end of the movable stop 6 which has the latching jaw 6" at the lower end is rotatably installed by the pin 1 ", and the inner upper part of the movable stop 6 is formed. The jaw 6 "'formed in the contacting cam 4 of the ratchet wheel 5 rotatably installed by the shaft pin 5" and the rotating pole (1) which is caught by the jaw 5' of the ratchet wheel 5 ( 8) is connected to the pole shift pin (8 ') and the pole shift pin (8') is installed in the case (9) with the spring (10) through the jaw (5) of the ratchet wheel (5) ') Is a structure in which the anti-rotation prevention forum 7 is locked.

이상과 같이 구성된 본 발명은 자력 흡착기의 자력 자동개폐장치인바 이의 실시상태를 설명하면 걸고리(13)에 호이스트의 걸림구를 걸어서 흡착기(1)를 이동시키고자하는 금형이나 철판위에 안치시킨 상태에서 리모콘을 가지고 호이스트를 작동시켜 증량체(3)를 들어올리면 증량체(3)는 좌우 안내간(11)을 따라 상승한다. 이와같이 상승하면 장공(3')내에 끼움 걸림된 링크(2)는 전개되면서 핸들(2"')이 회동함에 따라 흡착자력은 제3도와 같이 ON상태가 된다.According to the present invention configured as described above, when the magnetic force automatic switching device of the magnetic adsorber is described, the remote control unit is placed on the mold or the steel plate to move the adsorber 1 by hooking the hook of the hoist to the hook 13. When the hoist is operated to lift the extender 3, the extender 3 rises along the left and right guideways 11. In this way, as the handle 2 "'is rotated while the link 2 engaged in the long hole 3' is unfolded, the attracting magnetic force is turned on as shown in FIG.

다음 증량체(3)를 하강시켜 대판에 안치하면 이때 스프링(10)의 복원력에 의해 포올이동핀(8')은 상향됨에 따라 이의 하단에 형성된 턱(8"')은 래칫휘일(5)의 걸림턱(5')을 작동시켜 가동스토파(6)의 턱(6"')에서 벗어나게 한다.Next, when the extender 3 is lowered and placed on the base plate, the jaw 8 "'formed at the lower end of the ratchet wheel 5 is formed as the pole moving pin 8' is raised by the restoring force of the spring 10. The locking jaw 5 'is operated to be out of the jaw 6 "' of the movable stop 6.

따라서 가동스토파(6)은 자체의 무게에 의해 내향 이동하여 제4도표시와 같이 수직상태가 된다.Thus, the movable stop 6 moves inward by its weight and becomes vertical as shown in FIG.

이와같이 된 상태에서 호이스트를 다시 가동시켜 증량체(3)를 들어올리면 이때에는 좌우가동 스토파(6)의 걸림턱(6")은 흡착기(1)의 좌우측판에 돌설된 걸림핀(1')에 걸림되어짐과 동시 링크(2)는 장공(3')의 범위내에서 하강되나 핸들(2")은 제자리에 머물고 있기 때문에 자력 흡착기는 OFF상태이므로 흡착기만 단독으로 옮길 수 있게 된다.In this state, when the hoist is operated again to lift the extender 3, the locking jaws 6 ″ of the left and right movable stoppers 6 are engaged with the locking pins 1 ′ protruding from the left and right plates of the adsorber 1. And the simultaneous link 2 is lowered within the range of the long hole 3 ', but since the handle 2 "remains in place, the magnetic adsorber is OFF and only the adsorber can be moved alone.

즉, 호이스트를 이용하여 자력흡착기를 이동시킴에 있어 1차 올릴때는 흡착자력은 ON되고 2차 올린때 흡착자력은 OFF된 상태가 되는 것이며 이때 캠(4)은 증량체(3)가 1차 하강할시는 돌출부가 수직 방향되면서 가동스토파(6)를 내향되게하고 다음으로 2차 하강시는 돌출부가 돌출되어 가동스토파(6)를 외향이동시킴에 따라 이의 하단 걸림턱(6")은 걸림핀(1')에서 해지된다.In other words, when moving the magnetic adsorber using hoist, the adsorption magnetic force is turned on when the first time is raised and the adsorption magnetic force is turned off when the second time is raised, and the cam 4 has the first descending body of the extender 3. The halsey causes the movable stop 6 to move inward while the protrusion is vertical, and when the second descending, the lower stop jaw 6 ″ of the lower protrusion as the protrusion protrudes and moves the movable stop 6 outward. It is released from the locking pin 1 '.

이상과 같이 본 발명은 자력흡착기(1)의 상부에 돌설된 안내간(11)에 끼움된 증량체(3)가 1차로 상승될때시는 핸들(2"')이 상향 회동되면서 흡착자력을 ON되게하고 상승된 증량체가 1차로 하강되면 이때에는 핸들(2"')이 하향 회동되면서 흡착자력을 OFF되게함과 동시 포올이동핀(8')에 연결된 회전포올(8)은 래칫휘일(5)을 회동시켜 이에 부착된 3각형상의 캠(4)의 턱이 이동되면서 가동스토파(6)의 턱(6")에서 해지된다. 그리고 가동스토파(6)는 그 자체가 갖고 있는 무게에 의해 내향 이동되면서 이의 하단의 걸림턱(6")은 자력흡착기(1)는 OFF된 상태에서 상승하게 되므로서 이때에는 타물체를 흡착하지 않고 자력 흡착기(1)만 이동할 수 있게 하였기 때문에 생산 라인 자동화에 크게 기여할 수 있는 것이다.As described above, in the present invention, when the extender 3 inserted into the guide rod 11 protruding from the upper side of the magnetic adsorber 1 is first lifted, the handle 2 " When the raised extender is first lowered, the handle 2 " is rotated downward so that the adsorption magnetism is turned off and the rotary pole 8 connected to the simultaneous pool moving pin 8 'is ratchet wheel 5 The jaw of the triangular cam 4 attached thereto is moved and released from the jaw 6 "of the movable stop 6. And the movable stop 6 is driven by the weight itself. As it moves inwards, the locking jaw (6 ") at the bottom thereof is raised in the state where the magnetic adsorber (1) is turned off. At this time, only the magnetic adsorber (1) can be moved without adsorbing other objects. It can contribute greatly.
