Abstract

An emergency locking device through an acceleration sensor is provided to immediately stop a lifter by sensing rotary acceleration of a driving unit when the lifter falls free by a stoppage of power supply. An emergency locking device through an acceleration sensor includes a plate(4), a spool base(5), and an inertia plate(6). The plate is fixed at a frame of a returning device. One side of the spool base is fixed at a pulley driving shaft unit. The inertia plate senses revolutions per minute over predetermined speed. A suspending bar(8) with a groove I(7) is formed opposite to the spool base. A returning spring(11) is inserted in a spring coupling unit(20) formed at a front surface of a drive(12). A suspending cover(13) is coupled with the spool base and prevents separation of the suspending bar and the returning spring. The inertia plate and a sensing spring(14) to elastically support the inertia plate are mounted on a rear surface of the drive. A holder cover(18) fixes and contains a holder(16).

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. Plate 4 of the emergency locking mechanism (2) as shown in the figure is fixed to the frame 3 in the carrying device 1, the spool base 5 of the emergency lock (2) has one side pulley shaft portion It is fixed, and the inertia plate (6) incorporated in an emergency lock (2) to detect a rotation speed greater than that specified and, prior to operation does not affect the rotation of the drive shaft.

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. The teeth of gear shape formed on one side of the groove Ⅰ (7) formed on opposite side portions of the spool base 5 coupled with the pulley drive shaft portion, and a locking bar (8) built-in locking bar (8) is formed in the plate 4 is a bond or release the tooth ⅱ (17) is possibly configured.

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

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

드라이브(12)의 이면에는 관성판(6)과, 관성판(6)을 탄력지지하는 감지스프링(14)이 장착된다. If the drive 12 is equipped with a sensing spring (14) for elastically supporting the inertia plate 6 and the inertia plate (6).

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. Inertia plate (6) is the center of rotation the left and right pivot in an eccentric position to one side and can be mounted at one end are locking portions (15) being supported resilient by the detection spring 14 the other end of the drive (12) formed is constructed it can be coupled with the teeth on or off ⅰ (9) formed in the holder 16.

홀더커버(18)는 홀더(16)를 고정하고 수용하는 기능을 한다. The holder cover 18 has a function for fixing and accommodating the holder 16.

이하에서 상기와 같은 구성에 의한 긴급잠금장치의 작동을 설명한다. Hereinafter will be described the operation of the emergency locking device according to the configuration 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. Transport apparatus (1) the pulley driving the rotation, and a drive (12) coupled by friction to the shaft portion 19 of the spool base 5, the spool base 5 fixed to the lower pulley drive shaft rotates in the above specified rate of the Therefore, rotation is, the inertia plate (6) elastically supporting, by sensing spring 14 on the back surface of the drive 12 is responsive to rotational acceleration of the rotation about the center of rotation with the pin of the eccentric position of the drive (12) that is, is combined with a toothed ⅰ (9) of the inertial plate 6, the holder 16 by protruding the engaging part 15 formed at the ends in the circumferential direction of the drive 12 which is coupled with the drive 12 of the.

따라서 감지스프링(14)의 탄력은 관성판(6)을 작동하게 하는 회전가속도를 결정하며, 자유낙하방지를 위한 감지스프링(14)의 탄력은 통상 0.8G 이하에서 결정된다. Therefore, determining the rotational acceleration of the elasticity of the detection spring 14 acts the inertia plate 6, and the elasticity of the detection spring 14 for free-fall protection is determined by the normal 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. The rotation is stopped and also the spool base (5) of the drive 12 in accordance with operation of the inertia plate (6) continues to rotate while being embedded in the spool base 5, the return spring 11 is engaged with the spring engaging portion 20 It operates to protrude, while the compressed drive 12 and the retaining cover 13 and the projecting drive pin 22 is inserted into the locking bar (8) in the guide groove 21 formed in (12) 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. Locking bar (8), protrudes through by the rotation projecting pin 22 of the pin guide groove 21 there is formed long in the center of rotation of the drive (12) in the circumferential direction of the spool base 5 to 22 guide the and pushed out in the circumferential direction of the gear-like teeth formed in one end of the locking bar (8) to be coupled to the toothed ⅱ (17) of the sample rate (4) to stop the rotation of the spool base (5).

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. If there reverse rotation of the spool base 5, when you wish to turn off the emergency lock (2) by the elastic force of the return spring 11 engaging bar 8 and the drive 12, the elasticity of the original position while detecting spring 14 by locking pulley drive shaft portion by being a combination of the inertia plate 6 is released 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. The present invention whether or not the upper and the lower reason to sense the rotational acceleration of the drive even when going down to the lifter the free fall supply of a safety device which allows an emergency stop the power to the power failure in the transfer device for transfer as described above regardless of the reliability and the effect that can be provided by a simple configuration.
