도면에 도시된 바와 같이 긴급잠금장치(2)의 플레이트(4)는 반송장치(1)의 프레임(3)에 고정되며, 긴급잠금장치(2)의 스풀베이스(5)는 일측이 풀리구동축부에 고정되어 있고 긴급잠금장치(2)에 내장된 관성판(6)이 규정속도 이상의 회전을 감지하며, 작동하기 전에는 구동축의 회전에 영향을 미치지 않는다.As shown in the drawing, the plate 4 of the emergency locking device 2 is fixed to the frame 3 of the conveying device 1, and the spool base 5 of the emergency locking device 2 has one side of the pulley driving shaft. The inertial plate 6 fixed in the emergency locking device 2 and built in the emergency lock 2 senses rotation over a specified speed, and does not affect the rotation of the drive shaft before operation.

풀리구동축부와 결합되는 스풀베이스(5)의 반대측부에 형성된 홈Ⅰ(7)에는 걸림바(8)가 내장되며 걸림바(8)의 일측에 형성된 기어형상의 이빨은 플레이트(4)에 형성된 치형Ⅱ(17)와 결합 또는 해제가 가능하게 구성된다.In the groove I (7) formed on the opposite side of the spool base (5) coupled to the pulley driving shaft portion is a locking bar (8) is built in, the gear-shaped teeth formed on one side of the locking bar (8) is formed on the plate (4) Combination or disengagement with tooth type II (17) is possible.

스풀베이스(5)의 홈Ⅱ(10)에는 복귀스프링(11)이 복귀스프링(11)과 결합되는 드라이브(12)의 전면에 형성된 스프링 결합부(20)에 삽입되어 있다.In the groove II (10) of the spool base (5), a return spring (11) is inserted into a spring engaging portion (20) formed on the front surface of the drive (12) which is engaged with the return spring (11).

걸림커버(13)는 스풀베이스(5)에 결합되며, 걸림바(8)와 복귀스프링(11)의 이탈을 방지하는 역할을 수행한다.The catching cover 13 is coupled to the spool base 5 and serves to prevent separation of the catching bar 8 and the return spring 11.

드라이브(12)의 이면에는 관성판(6)과, 관성판(6)을 탄력지지하는 감지스프링(14)이 장착된다.On the rear surface of the drive 12, an inertial plate 6 and a sensing spring 14 for elastically supporting the inertial plate 6 are mounted.

관성판(6)은 드라이브(12)의 회전중심에서 한쪽으로 편심된 위치에 좌·우로 요동이 가능하게 장착되며, 일단은 감지스프링(14)에 의하여 탄력지지 되고 타단에는 걸림부(15)가 형성되어 홀더(16)에 형성된 치형Ⅰ(9)과 결합 또는 해제될 수 있 게 구성된다.The inertial plate 6 is rotatably mounted left and right at a position eccentrically to one side from the center of rotation of the drive 12, one end of which is elastically supported by the sensing spring 14, and the other end of the inertia plate 15 is engaged. It is formed and configured to be engaged or disengaged with the tooth I (9) formed in the holder (16).

홀더커버(18)는 홀더(16)를 고정하고 수용하는 기능을 한다.The holder cover 18 functions to fix and receive the holder 16.

이하에서 상기와 같은 구성에 의한 긴급잠금장치의 작동을 설명한다.Hereinafter will be described the operation of the emergency locking device by the configuration as described above.

반송장치(1)의 풀리구동부가 규정속도 이상으로 회전하면 풀리구동축에 고정된 스풀베이스(5)가 회전하고, 스풀베이스(5)의 축부(19)에 마찰력에 의하여 결합된 드라이브(12)가 따라서 회전되며, 드라이브(12)의 이면에서 감지스프링(14)에 의하여 탄력지지된 관성판(6)은 회전가속도에 반응하여 드라이브(12)의 회전중심과 편심된 위치의 핀을 중심으로 회동을 하게 되고, 관성판(6)의 단부에 형성된 걸림부(15)를 드라이브(12)의 원주방향으로 돌출시켜 드라이브(12)와 결합되는 홀더(16)의 치형Ⅰ(9)과 결합하게 된다.When the pulley drive part of the conveying apparatus 1 rotates more than the prescribed speed, the spool base 5 fixed to the pulley drive shaft rotates, and the drive 12 coupled to the shaft part 19 of the spool base 5 by the frictional force is Accordingly, the inertial plate 6 elastically supported by the sensing spring 14 on the rear surface of the drive 12 rotates around the center of rotation of the drive 12 and the pin in an eccentric position in response to the rotational acceleration. The protruding portion 15 formed at the end of the inertial plate 6 protrudes in the circumferential direction of the drive 12 to engage with the tooth type I 9 of the holder 16 engaged with the drive 12.

따라서 감지스프링(14)의 탄력은 관성판(6)을 작동하게 하는 회전가속도를 결정하며, 자유낙하방지를 위한 감지스프링(14)의 탄력은 통상 0.8G 이하에서 결정된다.Therefore, the elasticity of the sensing spring 14 determines the rotational acceleration to operate the inertial plate 6, the elasticity of the sensing spring 14 for preventing free fall is determined at 0.8G or less.

관성판(6)의 작동에 따라 드라이브(12)의 회전이 멈추어도 스풀베이스(5)는 계속 회전하면서 스풀베이스(5)에 내장되고 스프링 결합부(20)와 결합된 복귀스프링(11)을 압축하면서 드라이브(12)와 걸림커버(13) 및 드라이브(12)에 형성된 안내홈(21)에 돌출핀(22)이 삽입된 걸림바(8)를 원주방향으로 돌출되게 작동한다.Even if the rotation of the drive 12 stops due to the operation of the inertial plate 6, the spool base 5 continues to rotate while the return spring 11 embedded in the spool base 5 and coupled with the spring coupling part 20 is engaged. While compressing, the locking bar 8 in which the protruding pin 22 is inserted into the drive 12, the locking cover 13, and the guide groove 21 formed in the drive 12 is protruded in the circumferential direction.

걸림바(8)의 돌출핀(22)을 가이드하는 안내홈(21)은 드라이브(12)의 회전중심에서 원주방향으로 길게 형성되어 있어 스풀베이스(5)의 회전에 의하여 돌출핀(22)을 원주방향으로 밀어내어 걸림바(8)의 일단에 형성된 기어형상의 이빨이 플 레이트(4)의 치형Ⅱ(17)에 결합되게 하면서 스풀베이스(5)의 회전을 정지시킨다.The guide groove 21 for guiding the protruding pins 22 of the catching bar 8 is formed long in the circumferential direction at the center of rotation of the drive 12, thereby protruding the protruding pins 22 by the rotation of the spool base 5. The rotation of the spool base 5 is stopped while pushing in the circumferential direction so that the gear-shaped teeth formed at one end of the engaging bar 8 are engaged with the teeth II 17 of the plate 4.

긴급잠금장치(2)를 해제고자 할 시에는 스풀베이스(5)를 역회전시키면 복귀스프링(11)의 탄력에 의하여 걸림바(8)와 드라이브(12)가 원위치하면서 감지스프링(14)의 탄력에 의하여 관성판(6)의 결합이 해제됨으로서 풀리구동축부의 잠금은 해제된다.When the emergency locking device 2 is to be released, when the spool base 5 is rotated in reverse, the catching bar 8 and the drive 12 are repositioned by the elasticity of the return spring 11 and the elasticity of the sensing spring 14 is returned. By releasing the engagement of the inertial plate 6 by the lock of the pulley drive shaft portion is released.

이상에서 설명한 바와 같이 본 발명은 상·하 이송용의 반송장치에서 정전 등의 사유로 리프터가 자유낙하 하는 추락시에도 구동부의 회전가속도를 감지하여 긴급정지할 수 있게 하는 안전장치를 전원의 공급여부에 관계없이 신뢰성 있고 간편한 구성으로 제공할 수 있게 하는 효과가 있다.As described above, the present invention provides a safety device for detecting the acceleration of the rotation of the drive unit and emergency stop even when the lifter falls freely due to power failure, etc. Regardless, there is an effect that can be provided in a reliable and simple configuration.
