Description

자동문의 록킹장치{Locking device of an automatic door}Locking device of an automatic door

본 발명은 미닫이 방식의 자동문에 있어서, 센서에 의하지 않는 외부의 강압적인 힘에 의한 열림을 방지하기 위한 자동문의 록킹장치에 관한 것이다.The present invention relates to an automatic door locking device for preventing the door from being opened by a forcible external force not by the sensor in the sliding door.

일반적으로 미닫이 방식의 자동문은 강화유리문 상측의 일측에 감속기를 구비한 구동모터를 설치하여, 이 구동모터의 구동풀리와 타측의 종동풀리를 체인 또는 벨트 등의 구동벨트로 연결하고, 별도의 센서의 감지에 의해서나 또는 번호키, 카드키 등에 의하여 자동으로 도어를 여닫는 방식이다.In general, the automatic door of the sliding type is provided with a drive motor having a reduction gear on one side of the upper side of the tempered glass door, connecting the drive pulley of the drive motor and the driven pulley of the other side with a drive belt such as a chain or a belt, The door is automatically opened or closed by detection or by number keys or card keys.

이러한 자동문은 야간에는 작동을 하지 않도록 전원을 차단하여 구동모터의 작동을 정지시키게 되나, 만약에 발생할 수도 있는 수동에 의한 강제적인 열림을 방지하기 위해, 도 1에 도시된 바와 같이 강화유리문인 도어(1)의 상측 프레임(5)에 요홈(2)을 형성하고, 별도의 솔레노이드 밸브(4)를 구비한다. 그리고, 도어(1)가 닫힐때마다 솔레노이드 밸브(4)의 레버(4a)가 작동을 하여 상기 프레임(5)의 요홈(2)에 삽입되어 도어(1)의 열림이 제어되도록 한다.This automatic door is to stop the operation of the drive motor to cut off the power so as not to operate at night, in order to prevent the forcible opening by manual, which may occur, as shown in Figure 1 door (tempered glass door) A groove 2 is formed in the upper frame 5 of 1), and a separate solenoid valve 4 is provided. Each time the door 1 is closed, the lever 4a of the solenoid valve 4 is operated to be inserted into the recess 2 of the frame 5 so that the opening of the door 1 is controlled.

그리고, 센서(3)가 출입자를 감지하면, 상기 솔레노이드 밸브(4)가 다시 작동하여 레버(3a)가 상기 요홈(2)에서 제거되어 록킹상태가 해제되고, 구동모터가 동시에 작동하여 문을 좌우로 열게 되며, 출입자가 출입시마다 이와 같은 작동을 되풀이함으로 평상시에는 록킹장치의 기능이 무의미하나, 솔레노이드 밸브(4)의 레버(4a)가 프레임(5)의 요홈(2)에 삽입된 채로 전원을 차단하면, 그때는 수동에 의한 도어(1)의 열림이 차단되는 것이다.Then, when the sensor (3) detects the entrance, the solenoid valve (4) is operated again, the lever (3a) is removed from the groove (2) to release the locking state, the drive motor is operated at the same time left and right door The function of the locking device is insignificant as the person repeats this operation every time the person enters and exits, but the power is applied while the lever 4a of the solenoid valve 4 is inserted into the groove 2 of the frame 5. If blocked, the opening of the door 1 by manual operation will be blocked at that time.

그러나, 상기와 같은 종래의 록킹장치는 록킹이 된 상태에서 전원을 차단하고, 비상시에는 별도의 밧데리 등에 의해 작동을 하나, 만약 정전이나 화재 등으로 인하여 상기 센서에 전원이 공급이 되지 않아 작동을 하지 않으면, 도어의 록킹상태가 해제되지 않아 도어는 열리지 않게 되고, 오히려 상기 록킹장치로 인해 큰 위험이 따를 수도 있다.However, the conventional locking device as described above cuts off the power in the locked state, and operates by a separate battery in an emergency, but if the power is not supplied to the sensor due to a power failure or a fire, it does not operate. Otherwise, the locked state of the door is not released and the door does not open, rather, the locking device may present a great risk.

또한, 종래의 록킹장치는 록킹장치와 구동모터가 별도로 동작하기 때문에 그 동작이 일치하지 않을시는 록킹이 된 상태에서 구동모터가 회전을 하여 도어를 개방하려고 함에 따라 상기 구동모터에 무리가 가게 된다.In addition, in the conventional locking device, since the locking device and the driving motor operate separately, when the operation does not coincide, the driving motor is forced to rotate and open the door as the driving motor rotates in a locked state.

그리고, 출입자가 출입시마다 솔레노이드 밸브가 작동하고 해제됨에 따라 소음이 심하며, 밸브의 수명이 짧아지는 문제가 있다. 또한, 센서가 출입자를 감지하여도 솔레노이드 밸브의 록킹상태를 해제되어야 도어가 열리므로 반응시간이 많이 소요되는 등의 문제점이 있다.In addition, there is a problem that the noise is severe as the solenoid valve is operated and released every time the person enters and exits, and the life of the valve is shortened. In addition, even if the sensor detects an accessor, the door is opened only when the locking state of the solenoid valve is released.

본 발명은 상기와 같은 종래 자동문의 여러 문제점을 해결하고, 센서에 의하지 않고 비정상적인 외부의 힘에 의해 도어가 열릴 경우에만 작동하도록 하여, 솔레노이드 밸브의 수명을 연장하고, 소음을 줄이며, 출입자의 출입시 센서에 의한 도어의 작동시간을 최소화함에 본 발명의 목적이 있다.The present invention solves the problems of the conventional automatic door as described above, and operates only when the door is opened by an abnormal external force, not by the sensor, to extend the life of the solenoid valve, reduce noise, An object of the present invention is to minimize the operating time of the door by the sensor.

본 발명은 일반적인 자동문의 구성과 같이 감속기가 구비된 구동모터(10)가 설치되며, 이 구동모터(10)의 일측에는 구동풀리(11)를 구비하고, 일정 간격을 두고 타측에는 종동풀리(11a)를 구비하여 체인 또는 벨트 등의 구동벨트(12)로 연결하며, 도어(1)의 실내외에는 별도의 출입감지센서(3)를 각각 구비한다.The present invention is provided with a drive motor 10 is provided with a reduction gear as in the configuration of a general automatic door, one side of the drive motor 10 is provided with a drive pulley 11, the other side driven pulley 11a at a predetermined interval It is connected to the drive belt 12, such as a chain or a belt, and is provided with a separate entrance detection sensor (3) inside and outside the door (1).

그리고, 본 발명에서는 상기 구동모터(10)의 배면측에 구동축((10a)을 연장하여 회전체(13)를 일체로 고착하며, 이 회전체(13)에는 적어도 하나 이상의 삽입구(13a)가 천공된다. 또한, 상기 회전체(13)의 외주면 소정 위치에는 회전체(13)의 회전을 감지하는 회전감지센서(17)를 구비하여 도어(1)에 구비된 출입감지센서(3)와 연결한다.In the present invention, the drive shaft (10a) is extended to secure the rotor 13 integrally to the rear side of the drive motor 10, and at least one insertion hole 13a is drilled in the rotor 13. In addition, at a predetermined position on the outer circumferential surface of the rotating body 13, a rotation detecting sensor 17 for detecting rotation of the rotating body 13 is provided to connect with the access detecting sensor 3 provided in the door 1. .

상기 회전체(13)와 소정 간격으로 이격되는 위치에는 상기 회전감지센서(17)와 연설되는 솔레노이드 밸브(15)를 설치하고, 이 솔레노이드 밸브(15)의 레버(15a)와 일체로 연설된 고정판(14)을 구비하되, 상기 고정판(14)에는 삽입돌기(14a)를 상기 회전체(13)의 삽입구(13a)와 대접되도록 돌출한다.At the position spaced apart from the rotating body 13 at a predetermined interval, a solenoid valve 15 that is extended with the rotation detection sensor 17 is installed, and a fixed plate that is integrally extended with the lever 15a of the solenoid valve 15. (14), the fixing plate 14 protrudes so that the insertion projection (14a) to be in contact with the insertion hole (13a) of the rotating body (13).

그리고, 상기 솔레노이드 밸브(15)에는 타이머(16)를 부착하여 솔레노이드 밸브(15)의 작동시간을 제어하며, 정전을 대비하여 별도의 비상전원을 구비하는 것도 바람직하다.In addition, the solenoid valve 15 is attached to the timer 16 to control the operation time of the solenoid valve 15, it is also preferable to provide a separate emergency power in preparation for power failure.

이하, 본 발명의 작용을 설명하면 다음과 같다.Hereinafter, the operation of the present invention will be described.

본 발명에 따른 자동문의 상측에 별도로 구비되어 있는 출입감지센서(3)에 전원이 투입되면, 출입자를 감지하게 되고, 이렇게 출입자가 감지되면, 상기 출입감지센서(3)에서 보내오는 신호에 의해 구동모터(10)의 전원이 공급되어 작동을 한다. 그리고, 상기 구동모터(10)의 구동에 의해 구동벨트(11)가 움직이며 도어(1)가 개방되고, 일정시간이 지나면 다시 구동모터(10)가 역회전을 하면서 도어(1)가 닫힌다. 그리고, 야간 등 출입자의 출입을 통제하고자 할 때에는 상기 출입감지센서(3)또는 카드키 등의 전원을 차단함으로써, 도어(1)가 작동을 하지 않아 출입이 통제 된다.When power is supplied to the entrance detecting sensor 3 separately provided on the upper side of the automatic door according to the present invention, the entrance is detected, and when the entrance is detected, driving is performed by a signal sent from the entrance detecting sensor 3. Power of the motor 10 is supplied to operate. Then, the drive belt 11 is moved by the driving of the drive motor 10 and the door 1 is opened. After a predetermined time, the door 1 is closed while the drive motor 10 reverses rotation. And, if you want to control the entrance and exit of the night, such as the entrance detection sensor 3 or the card key, such as by cutting off the power, the door (1) does not operate the entrance is controlled.

그러나, 상기와 같이 출입감지센서(3) 또는 카드키 등의 작동에 의하지 않고, 수동 등의 외부 힘에 의해 도어가 열릴 시에는, 즉, 출입감지센서(3) 또는 카드키 등에서 보내오는 신호가 없이 도어(1)가 열림에 따라 구동모터(10)가 회전시에는 회전감지센서(17)가 감지를 하여 연설된 솔레노이드 밸브(15)를 작동시킨다.However, as described above, when the door is opened by an external force such as manual, without the operation of the entrance sensor 3 or the card key, that is, the signal from the entrance sensor 3 or the card key is transmitted. When the drive motor 10 is rotated as the door 1 is opened without rotation, the rotation sensor 17 detects and operates the solenoid valve 15 that is extended.

그러면, 상기 솔레노이드 밸브(15)의 레버(15a)가 일체로 구비된 고정판(14)을 밀게 되고, 상기 고정판(14)의 삽입돌기(14a)가 회전체(13)의 삽입구(13a)에 삽입되어 구동모터(10)의 회전을 록킹하게 된다.Then, the fixed plate 14, which is integrally provided with the lever 15a of the solenoid valve 15, is pushed, and the insertion protrusion 14a of the fixed plate 14 is inserted into the insertion hole 13a of the rotating body 13. As a result, the rotation of the driving motor 10 is locked.

따라서, 상기 구동모터(10)가 록킹됨에 따라, 도어(1)와 일체로 체결된 구동벨트(11)가 더 이상 움직이지 못하며, 결국에는 도어(1)의 개방이 제어되는 것이다. 그리고, 일정시간이 소요되면, 별도의 타이머(16)에 의해 솔레노이드 밸브(15)가 해제되어 고정판(14)이 상기 구동모터(10)의 회전체(13)에서 이격되어 록킹상태가 해제된다.Therefore, as the driving motor 10 is locked, the driving belt 11 integrally fastened with the door 1 no longer moves, and eventually the opening of the door 1 is controlled. When a predetermined time is required, the solenoid valve 15 is released by a separate timer 16 so that the fixed plate 14 is spaced apart from the rotating body 13 of the driving motor 10 to release the locked state.

한편, 출입감지센서(3) 또는 카드키 등의 신호에 의해 구동모터(10)가 회전시에는 상기 회전감지센서(17)가 작동을 하지 않으므로, 평상시에는 상기 솔레노이드 밸브(15)가 작동을 하지 않는다.On the other hand, since the rotation detection sensor 17 does not operate when the driving motor 10 is rotated by a signal such as an entrance detection sensor 3 or a card key, the solenoid valve 15 does not operate normally. Do not.

그리고, 인위적으로 전원을 차단하고, 즉, 회전감지센서(17)와 솔레노이드 밸브(15)에 공급되는 전원을 차단하고 도어(1)를 인위적으로 열고자 하면, 상기 구동모터(10)와 출입감지센서(3)는 작동을 하지 않아도 회전감지센서(17)와 솔레노이드 밸브(15)에는 별도의 비상전원이 투입되고 있으므로, 수동에 의하여구동모터(10)의 회전체(13)가 회전시에는 이를 회전감지센서(17)가 감지하여 솔레노이드 밸브(15)를 작동시켜 록킹함으로써, 도어(1)의 열림을 차단한다.And, artificially cut off the power, that is, to cut off the power supplied to the rotation sensor 17 and the solenoid valve 15 and artificially open the door 1, the drive motor 10 and the entrance detection Even if the sensor 3 does not operate, a separate emergency power is supplied to the rotation detection sensor 17 and the solenoid valve 15, and thus, when the rotating body 13 of the driving motor 10 is rotated manually. The rotation detecting sensor 17 senses the operation and locks the solenoid valve 15 to block the opening of the door 1.

이상과 같이 본 발명의 일실시예를 상세히 설명하였으나, 본 발명은 이에 한정되는 것은 아니며, 본 발명의 범위 내에서 변경, 변형하여 실시하는 것 또한 본 발명의 개념에 포함되는 것은 물론이다.Although one embodiment of the present invention has been described in detail as described above, the present invention is not limited thereto, and it is a matter of course that modifications and variations are also made within the scope of the present invention.

상기와 같이 본 발명은 센서의 감지에 의해 구동모터가 회전시에는 록킹장치가 작동을 하지 않으므로, 솔레노이드 밸브의 불필요한 작동이 줄고, 따라서, 소음이 줄어들며, 상기 솔레노이드 밸브의 수명을 연장할 수 있으며, 구동모터의 전원이 차단된 상태에서 록킹을 하므로, 구동모터에 무리가 가지 않는다.As described above, according to the present invention, since the locking device does not operate when the driving motor is rotated by the detection of the sensor, unnecessary operation of the solenoid valve is reduced, thus reducing noise and extending the life of the solenoid valve. Locking is performed when the power of the driving motor is cut off, so that the driving motor is not overwhelmed.
