본 고안은 프레스로 작업할때 작업자가 작업대에 손을 넣는 순간 작업대 전면양측에 장치된 적외선을 이용한 위험검출 광학장치인 I.C회로를 차단함으로서 족답간을 밟아주어도 승하강대가 다단으로(3단)정지토록 개량하여 안정성을 최대한으로 해결한 프레스의 자동제어 안전장치에 관한 것이다.The present invention blocks the IC circuit, which is a danger detection optical device using infrared rays installed on both sides of the workbench when the worker puts his hand on the workbench when working with the press. The present invention relates to an automatic control safety device for a press that has been improved for the most and solved the stability to the maximum.

종래에는 본원 출원인이 선등록한 80-250호와 82-1943호의 부분적인 미비점을 완전하게 개량한 것으로서 작용은 동일하나 구조적인 장치를 개량함으로서 제동효과가 월등히 높고 다단(3단)으로 승하강대가 정지 제동토록 함으로서 안전효과를 상승케한 것으로서 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Conventionally, the partial deficiency of 80-250 and 82-1943, which was previously registered by the applicant of the present application, is completely improved. The function is the same, but the structural device is improved, and the braking effect is extremely high. When it is described in detail by the accompanying drawings as to increase the safety effect by braking as follows.

휘일대기어(12)의 축공(13)주면에 홈턱(14)을 구성하고 클러치(15)에는 걸림턱(16)과 요홈조(17)을 형성한 후단에 고정금구(18)를 고착하여 걸쇠턱(19)과 일체로된 걸쇠간(19')을 스프링(20)으로 탄지한 것에 있어서, 내면에 요구(22)를 형성하고 열쇠사면부(23)를 형성한 다음 외주면에 다수개의 제동돌기(24)를 튀여나오게 설치한 제동관(21)을 클러치(15)에 관삽하고 제동핀(27)으로 역회전을 방지케한 다음 고정링(25)을 고정하고 일측은 제동관(21)과 타측은 고정링(25)에 고정시킨 탄발스프링(28)을 권선하여서 된 것이다.A groove jaw 14 is formed on the main surface of the shaft hole 13 of the wheel standby gear 12, and the fastening bracket 18 is fixed to the rear end of the clutch 15 to form a catching jaw 16 and a concave groove 17. In holding the clasp 19 'integrated with the jaw 19 with the spring 20, a request 22 is formed on the inner surface, a key slope portion 23 is formed, and then a plurality of brake protrusions are formed on the outer peripheral surface ( Insert the braking tube 21 protruding from the 24 into the clutch 15 and prevent the reverse rotation with the braking pin 27. Then, the fixing ring 25 is fixed and one side is braking tube 21 and the other side. The side is made by winding the ball spring 28 fixed to the fixed ring (25).

이와같이된 본고안의 작용효과를 설명하면 다음과 같다. 본 고안의 설치는 선원인 80-250호, 82-1943호 등과같이 작업대위에 적외선 램프를 설치하여 작업자가 작업대에 손을 넣고 족답간을 실수로 밟았을지라도 작업대에 설치된 적외선 회로에서 정지하게 되어 제동됨으로 다치지 않게 되는 것인데, 족답을 밟으면(미도시됨) 제동간(10)이 안내구(11)내에서 제동관(21)과 제동돌기(24)에 걸려있다가 아래로 빠지게 되면, 휘일대기어(12)와 클러치(15) 및 제동관(21)과 제동돌기(24) 고정링(25)등이 회전하게되며 동시에 상부금형이 부착된 렘(미도 시됨)이 하강하여 하부금형과 일치되어 제품을 성형하는 작업을 하게된다. (렘은 통상의 것과 같이 크랭크축에 장치되어 있다) 이때에 제동간(10)이 제동돌기(24)에서 탈리되면서 동력이 전달되는 것은 동력의 힘으로 회전되고 있는 휘일대기어(12)의 홈턱(14)에 걸쇠간(19')가 끼워지게 되어 클러치(15), 제동관(21), 고정링(25)이 일체로되어 크랭크축(26)과 함께 회전된다. 즉 제동간(10)이 제동돌기(24)에 걸려있을 때는 제동관(21)의 열쇠사면부(23)가 걸쇠턱(19)에 걸려서 후진되어 걸쇠간(19')가 홈턱(14)에서 탈리되기 때문이다.The effect of this paper is explained as follows. The installation of the present invention installs an infrared lamp on the workbench such as crews 80-250, 82-1943, etc. so that even if the worker puts his hand on the workbench and stepped step by step, it stops at the infrared circuit installed on the workbench. When stepping (not shown), the braking rod 10 is caught in the braking tube 21 and the braking protrusion 24 in the guide 11, and then falls down. The gear 12, the clutch 15, the brake tube 21, the brake protrusion 24, the fixing ring 25, etc. rotate, and at the same time the upper mold is attached to the lower RAM (not shown) to coincide with the lower mold. It will work to mold the product. (The rem is mounted on the crankshaft as usual.) At this time, the power is transmitted as the brake 10 is detached from the brake protrusion 24. The groove jaw of the wheel stand gear 12 that is rotated by the power of the power is rotated. The clasp 19 'is fitted to the 14 so that the clutch 15, the braking tube 21, and the fixing ring 25 are integrally rotated together with the crankshaft 26. That is, when the brake section 10 is caught on the brake protrusion 24, the key slope 23 of the brake tube 21 is caught by the latch jaw 19, so that the latch 19 'is detached from the groove jaw 14. Because it becomes.

이렇게 되어서 걸쇠간(19')가 홈턱(12)에 끼워지게 되어 휘일대기어(12)의 회전되는 동력이 클러치(15), 제동관(21), 고정링(25)과 함께 클랭크축(26)을 회전시켜서 크랭크축(26)에 통상의 것과 같이 연결 장치된 렘이 하강과 상승작용을 반복하고 렘하부에는 상부금형이 부착되어 있어서 기대의 하부금형과 일치되어 제품이 성형된다. 그리고 걸쇠간(19')이 홈턱(14)에서 탈리되어 휘일대기어(12)의 회전동력을 차단하는 것은 제동간(10)이 상승하여 제동관(21)의 제동돌기(24)에 걸려지는 순간 제동관(21)이 약간 좌회전하면서 열쇠사면부(23)가 걸쇠간(19)을 후진시켜 줌으로 걸쇠간(19')은 후진방향(도면 도시에서는 좌측방향) 밀려서 홈턱(14)에서 탈리되며, 탈리되는 순간 휘일대기어(12)만 공회전하고 클러치(15), 제동관(21), 고정링(25), 및 크랭크축(26)은 정지된다.In this way, the clasp 19 'is fitted to the groove jaw 12 so that the rotating power of the wheel gear 12 becomes the crankshaft 26 together with the clutch 15, the braking tube 21, and the fixing ring 25. Rom) connected to the crankshaft 26 as usual by the rotation of the) repeats the descending and synergistic action, and the upper part is attached to the lower part of the ram, so that the product is molded in accordance with the lower mold of the base. And the clasp 19 'is detached from the groove jaw 14 to block the rotational power of the wheel gear 12 is the braking rod 10 is raised to be caught by the brake protrusion 24 of the braking tube 21 As the brake tube 21 rotates slightly to the left, the key slope 23 reverses the latch 19 so that the latch 19 'is pushed in the reverse direction (left in the drawing) and detached from the groove 14. At the moment of detachment, only the wheel standby gear 12 idles and the clutch 15, the braking tube 21, the fixing ring 25, and the crankshaft 26 are stopped.

다시 말해서 족답을 밟은 상태에서 상부금형이 부착된 렘이 하강도중 작업자가 하부금형 위치에 손이들어 가는 순간 광학I.C회로를 차단하면, 제동간(10) 중단에 형성된 공지의 마그네트에 자력이 상실되어 족답만 밟아지고 제동간(10)은 상승하여 제동돌기(24)에 걸림과 동시에 걸쇠간(19')이 홈턱(14)에서 탈리되어 휘일대기어(12)만 공회전하고 크랭크축(26)의 동작이 순간 정지되어 렘 또한 정지함으로 작업자의 손이 하부 금형위치에 있어도 안전하게 된다.In other words, if the RAM is attached to the upper mold while stepping on, and the operator cuts the optical IC circuit at the moment of entering the lower mold position during the descent, the magnetic force is lost to the known magnet formed at the middle of braking 10. Only stepping on the step, the braking rod 10 is raised and caught on the brake protrusion 24, and at the same time the clasp 19 'is detached from the groove jaw 14, and only the wheel gear 12 is idle, and the crankshaft 26 The movement stops momentarily and the RAM also stops, making it safe even if the operator's hand is in the lower mold position.

또 제동핀(27)의 역활은 클러치(15)의 요홈조(17)주면에 고정시켜서 제동관(21)의 우회전(초과회전)을 정지시키는 고정역활을 하는 것인데, 제동간(10)이 제동관(21)의 제동돌기(24)에 걸렸을때 좌회전을 하면서 열쇠사면부(23)가 걸쇠턱(19)을 걸어서 좌측으로 밀어내면 걸쇠간(19')가 후진되어 홈턱(14)에서 탈리시키는 작용을 시킨후 즉답간을 밟아서 제동간(10)을 하향시켜 제동돌기(24)에서 탈리되는 순간 제동관(21)은 우회전(원위치)하여 열쇠사면부(23)가 걸쇠턱(19)을 후진시켰던 상태에서 탈리되어 걸쇠간(19')가 홈턱(14)에 끼워지도록 하는데, 제동관(21)이 우회전을 시키는 것은 탄발스프링(28)의 힘으로 이루어지며 이 탄발스프링(21)의 탄력에 제동관(27)을 초과회전을 저지시켜야하는데 초과회전의 저지는 제동핀(28)이 저지한다.In addition, the role of the braking pin 27 is fixed to the main surface of the groove groove 17 of the clutch 15 to play a fixed role of stopping the right turn (overturn) of the braking tube 21, the braking interval 10 is When the locking projection 24 of the copper tube 21 is turned to the left while the key slope 23 pushes the latch jaw 19 to the left, the latch 19 'is retracted to detach from the groove 14. After stepping on the immediate response, the brake section 10 is lowered and the brake tube 21 is rotated right (the home position) when the brake tube 21 is detached from the brake protrusion 24 so that the key slope 23 reverses the latch jaw 19. It is detached from the clasp 19 'to be fitted to the groove jaw (14), the braking tube 21 to the right turn is made of the force of the bullet spring 28 and the braking tube to the elasticity of the bullet spring (21) (27) should be prevented from overturning, which is prevented by the braking pins 28.

즉, 탄발스프링(21)은 일단이 제동관(21)에 고정하여 고정링(25)의 외주면으로 권취하여 타단은 고정링(21)의 일단에 고정하였기 때문에 제동관(24)의 제동돌기(10)에 제동간(10)이 걸려서 좌회전 후 제동간(10)이 탈리되는 순간 탄발스프링(28)의 힘으로 제동관(21)이 원위치(우회전)할 때 정위치에서 정지하도록 제동핀(27)이 저지시키게 된다. 다시 말해서 탄발스프링(28)은 제동관(21)을 원위치시켜 다음작동의 대비상태에 있게 해 준다.That is, since the one end is fixed to the braking tube 21 and wound around the outer circumferential surface of the fixing ring 25, and the other end is fixed to one end of the fixing ring 21, the braking protrusion of the braking tube 24 ( The brake pin 10 stops at the correct position when the brake tube 21 is homed (right) by the force of the bullet spring 28 at the moment when the brake rod 10 is caught and the brake rod 10 is detached after the left turn is caught. Hindered). In other words, the bullet spring 28 returns the brake tube 21 to the ready state for the next operation.

열쇠사면부(23)은 제동관(21)이 회전될 때 걸쇠턱(19)의 사면과 접속되어 걸쇠간(19')을 후진시켜 홈턱(14)에서 빠지는 작용을 하며 이 작동은 제동간(10)이 제동돌기(24)에 걸려있을때 이루어지고, 탄지스프링(20)은 밀려나서 후진된 걸쇠턱(19)과 걸쇠간(19')을 원위치시키는 작용을 하게 된다.The key slope 23 is connected to the slope of the latch jaw 19 when the braking tube 21 is rotated so as to retract the clasp 19 'so as to fall out of the groove jaw 14. ) Is made when the brake projection 24 is hung, the stop spring 20 is pushed back to act to retract the latch chin 19 and the clasp 19 '.

이와같이 된 본 고안은 그 구성이 종래의 것의 광선을 차단한 상태에서만 작동을저지하던 것과는 달리 일단 광선을 차단하는 순간 하강하던 상부금형의 렘이 하강도 중에서 급정지가 정확, 신속하게 이루어지는 효과적인 것이다.The present invention thus achieved is effective that the stop of the upper mold, which is lowered at the moment of blocking the light, is rapidly and accurately stopped, unlike the construction of the conventional light-blocking operation only in the state of blocking the light.
