Description

DC모타로 구동되는 방화셔터의 DC자동폐쇄기DC automatic closing machine of fire shutter with DC motor

본 발명은 화재시 셔터가 자중에 의하여 자동적으로 하강할 경우에 바닦면에서 셔터가 정확하게 순간적으로 정지토록하여 셔터판이 찌그러지지 않토록 함으로서 셔터의 고장 방지 및 비상문이 쉽게 열릴 수 있도록 되는 방화셔터의 DC자동폐쇄기에 관한 것이다.According to the present invention, when the shutter is automatically lowered by its own weight in case of fire, the shutter stops precisely and instantaneously at the bottom so that the shutter plate is not crushed, thereby preventing the failure of the shutter and easily opening the emergency door. DC automatic closing machine.

종래의 자동폐쇄기는 AC전원을 이용하여 솔레노이드가 제5도에 도시된 바와 같이 작동축(100)이 후진된 상태에서 작동스프링(101)이 가압되어 있고 작동축(100)의 후방으로는 걸림돌기(102)가 형성되어 솔레노이드(103)의 작동에 의하여 솔레노이드의 가동축(104)이 전후진 될 경우에 탄지스프링(108)에 의하여 탄지되어 있는 개폐축(106)이 후진되면 개폐축(106)과 가동로라(105)의 삼각점에 형성된 회 동축(107)에 의하여 유동되어지는 가동로라(105)가 상승하면서 가동로라(105)에 의하여 걸려 있던 작동축(100)의 걸림돌기(102)가 탈리되면서 작동축(100)을 가압하고 있던 작동스프링(101)의 복원력에 의하여 작동축(100)이 전진하면서 셔터(200)의 전동개폐기(201)의 작동핀(202)을 밀어서 셔터(200)의 자중에 의하여 강하토록 되고 강하가 완료되면 전동개폐기(202)의 내부에 장착되어 있는 리미트스위치(203)에 의하여 자동폐쇄기에 AC전원을 공급하여 상술한 바와 같이 작동축(100)을 당기게 됨으로서 강하되는 셔터가 정지토록 되어 있는 것이다.In the conventional automatic closing machine, the operating spring 101 is pressed in the state in which the solenoid is reversed as shown in FIG. 5 by using AC power, and the locking projection is located behind the operating shaft 100. The opening and closing shaft 106 is formed when the opening and closing shaft 106 supported by the tanger spring 108 is moved backward when the movable shaft 104 of the solenoid is moved back and forth by the operation of the solenoid 103. And the engaging protrusion 102 of the operating shaft 100 held by the movable roller 105 is lifted while the movable roller 105 which is flowed by the rotating shaft 107 formed at the triangular point of the movable roller 105 is detached. While the operating shaft 100 is advanced by the restoring force of the operating spring 101 which is pressing the operating shaft 100, the operating pin 202 of the electric switch 201 of the shutter 200 is pushed to When the descent is completed by its own weight and the descent is completed, the electric switch 202 By being pulled by the operation shaft 100, as described above, by supplying the AC power to the pyeswaegi automatically by the limit switch 203, which apparently is ever shutter is stopped dropping.

이때 리미트스위치는 셔터가 상승이나 하강할 경우에 나사산축으로 형성된 스위치에 의하여 상기 스위치가 좌우로 이동되면서 리미트스위치를 작동토록 하는 것이다.At this time, the limit switch is to operate the limit switch while the switch is moved left and right by a switch formed by a screw shaft when the shutter is raised or lowered.

그러나 이러한 방식은 셔터가 강하될 경우의 속도가 상당히 빠른 상태에서 하강되기 때문에 순간적으로 정지토록 하지 않을 경우에는 셔터가 바닦묜보다 더 많이 풀리게 되면서 셔터가 쭈글쭈글하에 되어 이러한 현상으로 인하여 셔터의 고장과 비상문이 열리지 않게 되는 문제가 발생되는 것이다.However, this method lowers the speed of the shutter when it is lowered, so if the shutter is not stopped momentarily, the shutter is released more than the shutter, and the shutter is shriveled. The problem is that the emergency door does not open.

또한 셔터가 강하될 경우는 대부분 화재가 발생될 경우이기 때문에 화재에 의하여 전원이 차단될 경우에는 AC전원이 차단됨으로서 셔터의 자동개폐기의 작동핀을 밀고 있는 자동폐쇄기의 작동축을 후진 시키지 못하기 때문에 셔터가 완전히 풀릴때까지 강하토록 되어 셔터를 연결하고 있는 셔터판이 찌그러지면서 셔터의 고장으로 인한 경제적인 손실과 이로 인하여 셔터의 일측에 형성된 비상문이 열리지 않게 되는 문제점이 있었던 것이다.In addition, when the shutter is lowered, most of the time, a fire occurs. When the power is cut off due to a fire, the AC power is cut off. Therefore, the operation shaft of the automatic closure that pushes the operation pin of the automatic closure of the shutter cannot be reversed. It is to be lowered until the fully released, the shutter plate connecting the shutter is distorted, there is a problem that the economic loss due to the failure of the shutter and thereby the emergency door formed on one side of the shutter does not open.

따라서 본 발명에서는 이러한 문제점의 해결을 위하여 작동축의 전진을 모타의 가동에 의하여 회전기어에 장착된 가동돌기가 작동축의 작동요홈 일측에 형성된 걸림턱에 의하여 전진토록 하고 동시에 가동돌기의 대칭축에 장착된 스위치가동돌기는 리미트스위치를 작동토록하여 작동축이 전진된 후에는 모타의 작동이 정지토록하여 작동축이 전진된 상태를 유지토록 하고 이후 솔레노이드의 작동에 의하여 탄지스프링(108)에 의하여 탄지되어 후진되어 있는 개폐축(106)이 전진되면 개폐축(106)과 가동로라(105)의 삼각점에 형성된 회동축(107)에 의하여 유동되어지는 가동로라(105)가 하강하면서 가동로라(105)에 의하여 걸려 있던 작동축(100)의 걸림돌기(102)가 탈리되면서 작동축(100)의 전진에 의하여 늘어나 있는 작동스프링(101)의 복원력에 의하여 작동축(100)이 순간적으로 후진하면서 셔터가 순간적으로 정지토록 되는 것이다.Therefore, in order to solve the above problems, in the present invention, the movable projection is mounted on the rotary gear by moving the motor to move forward by the locking step formed on one side of the working recess of the operating shaft, and at the same time, the switch is mounted on the symmetric axis of the movable projection. The movable projection causes the motor to stop after the operating shaft is advanced by operating the limit switch so that the operating shaft is kept in an advanced state, and then is driven and retracted by the tangy spring 108 by the operation of the solenoid. When the open / close shaft 106 is advanced, the movable roller 105 which is flowed by the open / close shaft 106 and the rotating shaft 107 formed at the triangular point of the movable roller 105 descends and is caught by the movable roller 105. Operating shaft (1) by the restoring force of the operating spring 101 is extended by the advance of the operating shaft 100 while the engaging projection 102 of the operating shaft 100 was detached 00) momentarily reverses, the shutter stops momentarily.

제1도 내지 제4도에 도시된 바와 같이 본 발명의 구성은 기판(20)에 작동축(1)의 선단과 후단이 전후진 될 수 있도록 일측으로 절곡된 격판(30)에 출입구멍이 절개되어 있고 작동축(1)의 중앙부분에는 작동축(1)이 탄성력에 의하여 작동될 수 있도록 스프링(9)의 일단이 고정되어 지는 지지판(40)이 기판(20)에 나착되고 작동축(1)의 지지판(40)과 기판(20)의 절곡된 격판(30)의 사이로는 상면으로 일정간격으로 절개된 절개요홈(7)이 형성되고 절개요홈(7)의 일측전방으로는 회전기어(2)의 가동돌기(3)가 걸려질 수 있도록 걸림턱(8)이 형성되고 스프링(9)의 타측단은 작동축(1)에 고정되어 스프링(9)이 탄지토록 되는 것이다.As shown in FIG. 1 to FIG. 4, the configuration of the present invention allows the substrate 20 to have an access hole cut into the plate 30 bent to one side so that the front and rear ends of the operating shaft 1 can be advanced back and forth. At the center of the operating shaft 1, a support plate 40 on which one end of the spring 9 is fixed is fixed to the substrate 20 so that the operating shaft 1 can be operated by an elastic force. Between the support plate 40 and the bent diaphragm 30 of the substrate 20 is formed an incision groove (7) cut at a predetermined interval to the upper surface and a rotary gear to one side of the incision groove (7) The locking jaw 8 is formed so that the movable projection 3 of (2) can be caught, and the other end of the spring 9 is fixed to the operating shaft 1 such that the spring 9 is held.

또한 절개요홈(7)의 걸림턱(8)에 걸려져서 작동축(1)을 전진시키는 회전기어(2)의 가동돌기(3)의 대칭축으로는 스위치가동돌기(12)가 형성되어 스위치(11)를 가동시키게 되는 것이고 회전기어(2)는 작동기어(4)와 기어맞물림 되어있고 작동기어(4)는 모타축(6)에 고정되어 있는 것이다.In addition, a switch movable protrusion 12 is formed as a symmetrical axis of the movable projection 3 of the rotary gear 2 which is caught by the locking jaw 8 of the cutout recess 7 and advances the operating shaft 1. 11) and the rotary gear 2 is in gear mesh with the actuating gear 4 and the actuating gear 4 is fixed to the motor shaft 6.

이때 솔레노이드(10)의 작동은 탄지스프링(108)에 의하여 탄지되어 후진되어 있는 개폐축(106)이 전진되면 개폐축(106)과 가동로라(105)의 삼각점에 형성된 회동축(107)에 의하여 유동되어지는 가동로라(105)가 하강하면서 가동로라(105)에 의하여 걸려 있던 작동축(1)의 걸림돌기(102)가 탈리되면서 작동축(1)의 전진에 의하여 늘어나 있는 스프링(9)의 복원력에 의하여 작동축(1)이 순간적으로 후진하면서 셔터가 즉시 정지토록 되는 구성이다.At this time, the operation of the solenoid 10 is moved by the rotating shaft 107 formed at the triangular point of the opening and closing shaft 106 and the movable roller 105 when the opening and closing shaft 106, which is supported by the tangy spring 108 is advanced. As the movable roller 105 being lowered descends, the engaging protrusion 102 of the operating shaft 1 held by the movable roller 105 is detached and thus the spring 9 extending by the advancement of the operating shaft 1. It is a configuration in which the shutter is stopped immediately while the operating shaft 1 momentarily reverses due to the restoring force.

따라서 화재 등의 발생으로 연기를 감지하면 연동제어기(도시안됨)의 감지기에서 신호를 발생시키면 그 신호에 의하여 전원이 모타(5)에 공급되면서 작동기어(4)가 회전되면서 작동기어(4)에 맞물려 있는 회전기어(2)가 회전하면서 회전기어(2)의 가동돌기(3)가 작동축(1)의 절개요홈(7)의 걸림턱(8)에 밀착되면서 작동축(1)이 전진하게 되면 전진된 작동축(1)이 셔터의 전동개폐기의 작동핀을 가압하면 셔터를 권취하고 있는 셔터축이 풀리게 되면서 셔터의 자중에 의하여 하강을 하게 되는 것이다.Therefore, when the smoke is detected by the occurrence of a fire or the like, when a signal is generated by the detector of the interlocking controller (not shown), the power is supplied to the motor 5 by the signal, and the operating gear 4 is rotated, thereby operating on the operating gear 4. As the meshed rotary gear 2 rotates, the movable projection 3 of the rotary gear 2 comes into close contact with the engaging jaw 8 of the cutout recess 7 of the operating shaft 1, and the operating shaft 1 moves forward. When the advanced operation shaft (1) presses the operation pin of the electric switch of the shutter is released by the self-weight of the shutter while the shutter shaft winding the shutter is released.

이때 회전기어(2)의 가동돌기(3)의 대칭축에는 스위치가동돌기(12)가 형성되어 스위치(11)의 작동을 유도하는 것이고 이러한 스위치(11)의 작동에 의하여 솔레노이드(10)에 신호를 보내게 되면서 일정시간이 경과되면 솔레노이드(10)가 작동토록하여 전진되어 있는 작동축(1)을 순간적으로 후진토록하여 전동개폐기의 가압하고 있던 작동핀을 풀어주게 되면서 강하되던 셔터는 순간적으로 멈추게 되는 것이다.At this time, the switch movable projection 12 is formed on the symmetric axis of the movable projection 3 of the rotary gear 2 to induce the operation of the switch 11 and the signal to the solenoid 10 by the operation of the switch 11. When a certain time elapses while the solenoid 10 is operated, the solenoid 10 is momentarily retracted to release the actuating pin that is pressed by the electric switchgear, and then the shutter is stopped momentarily. will be.

이때 작동축(1)의 후단에 형성된 경사돌기(13)는 리미트스위치(14)를 ON,OFF시키도록 함으로서 연동제어기의 타이머에 의하여 단계적으로 셔터를 하강시킬 수 있게 되는 것이다At this time, the inclined protrusion 13 formed at the rear end of the operating shaft 1 allows the limit switch 14 to be turned on and off so that the shutter can be stepped down by the timer of the interlock controller.

따라서 작동축의 동작을 모타에 의하여 가동시키게 됨으로서 정확한 전진을 유도할 수 있게 되면서 동시에 작동축의 후진을 솔레노이드를 이용하여 작동시킴으로서 강하되던 셔터가 순간적으로 멈추 ㅕ지도록 함으로서 셔터가 쭈글쭈글하게 되지않고 펼쳐진 상태를 유지토록 함으로서 비상문이 열리지 않게 되는 문제점을 해결할 수 있게 된 것이고 셔터의 고장을 방지할 수 있는 것이다.Therefore, by operating the operation of the operating shaft by the motor, it is possible to induce the correct forward and at the same time operate the reverse of the operating shaft by using the solenoid, so that the descending shutter stops instantaneously and stops the shutter unfolded. By maintaining it, it is possible to solve the problem that the emergency door does not open and to prevent the failure of the shutter.
