Abstract

In an elevator device, an elevator car is caused to ascend and descend by a drive device.  A brake device brakes ascending and descending motion of the elevator car.  The drive device and the brake device are controlled by an operation control means.  The elevator car and a landing have elevator doors.  A first door-closure detecting means detects closure of the elevator doors.  A second door-closure detecting means detects the closure of the elevator doors independent of the first door-closure detecting means.  Based on signals from the first and second door-closure detecting means, a braking force release permitting means selects whether or not braking force of the brake device is to be released.

A brake coil control switch 17 that controls energization to the brake coil 7a is provided between the brake coil contact portion 16b and the grounding portion 15b. For example, a semiconductor switch is used as the brake coil control switch 17.
　ブレーキコイル制御スイッチ１７のオン・オフは、運転制御手段１４により制御される。即ち、ブレーキ装置７による制動力の印加・解除は、運転制御手段１４により制御される。 The on / off of the brake coil control switch 17 is controlled by the operation control means 14.

The braking force release permission means 20 switches on / off of the relay control switch 19, that is, whether the braking force of the brake device 7 can be released, based on signals from the first and second door closing detection means 21, 22. .
　第１のドア閉鎖検出手段２１は、かごドア閉鎖検出器１１及び乗場ドア閉鎖検出器１３ａ～１３ｃを含み、かごドア１０及び乗場ドア１２ａ～１２ｃの閉鎖を検出する。第２のドア閉鎖検出手段２２は、かごドア１０及び乗場ドア１２ａ～１２ｃの閉鎖を第１のドア閉鎖検出手段２１とは別に（独立して）検出する。 The first door closing detection means 21 includes a car door closing detector 11 and landing door closing detectors 13a to 13c, and detects closing of the car door 10 and the landing doors 12a to 12c. The second door closing detection means 22 detects the closing of the car door 10 and the landing doors 12a to 12c separately (independently) from the first door closing detection means 21.
　制動力解除許可手段２０は、かごドア１０及び乗場ドア１２ａ～１２ｃの少なくとも１つが開放されていることが第１及び第２のドア閉鎖検出手段２１，２２の両方により検出されているときに、リレー制御スイッチ１９をオフにし、ブレーキコイル接点部１６ｂを開き、ブレーキ装置７の制動力の解除を不可とする。 The braking force release permission means 20 is detected when both the first and second door closing detection means 21 and 22 detect that at least one of the car door 10 and the landing doors 12a to 12c is opened. The relay control switch 19 is turned off, the brake coil contact portion 16b is opened, and the braking force of the brake device 7 cannot be released.

　図３は図１のかごドア１０の開閉機構部のかごドア全閉時の状態を示す正面図、図４は図３の開閉機構部のかごドア全開時の状態を示す正面図である。かごドア１０は、第１及び第２のかごドアパネル１０ａ，１０ｂを有している。かご１の前面の上部には、ドア桁２３が固定されている。ドア桁２３には、第１及び第２のかごドアパネル１０ａ，１０ｂの開閉動作を案内するハンガレール（図示せず）が固定されている。 3 is a front view showing a state in which the car door is fully closed in the opening / closing mechanism of the car door 10 in FIG. 1, and FIG. 4 is a front view showing a state in which the car door is fully opened in the opening / closing mechanism in FIG. The car door 10 includes first and second car door panels 10a and 10b. A door girder 23 is fixed to the upper part of the front surface of the car 1. Hanger rails (not shown) for guiding the opening and closing operations of the first and second car door panels 10a and 10b are fixed to the door beam 23.
　ドア桁２３の長手方向両端部には、第１及び第２のプーリ２４，２５が設けられている。第１及び第２のプーリ２４，２５には、無端状のベルト２６が巻かれている。第１のプーリ２４は、ドアモータ（図示せず）により回転される。第２のプーリ２５は、第１のプーリ２４の回転がベルト２６を介して伝達されることにより回転される。 1st and 2nd pulleys 24 and 25 are provided in the longitudinal direction both ends of the door beam 23. An endless belt 26 is wound around the first and second pulleys 24 and 25. The first pulley 24 is rotated by a door motor (not shown). The second pulley 25 is rotated when the rotation of the first pulley 24 is transmitted via the belt 26.
　第１のかごドアパネル１０ａは、第１の接続部材（第１のアングル）２７を介してベルト２６の上側部分に接続されている。第２のかごドアパネル１０ｂは、第２の接続部材（第２のアングル）２８を介してベルト２６の下側部分に接続されている。ドアモータにより第１のプーリ２４が回転されると、第１及び第２のかごドアパネル１０ａ，１０ｂは、互いに逆方向へ移動され開閉される。 The first car door panel 10 a is connected to the upper portion of the belt 26 via a first connecting member (first angle) 27. The second car door panel 10 b is connected to the lower portion of the belt 26 via a second connection member (second angle) 28. When the first pulley 24 is rotated by the door motor, the first and second car door panels 10a and 10b are moved in opposite directions and opened and closed.
　かごドア閉鎖検出器１１は、ドア端同士の接触を検出することによりかごドア１０の閉鎖を検出する。また、かごドア閉鎖検出器１１には、安全側の故障（かごドア１０が閉鎖しているのに開放していると誤検出する故障）しか発生しない。即ち、かごドア１０が開放しているのに閉鎖していると誤検出することはない。さらに、乗場ドア閉鎖検出器１３ａ～１３ｃも、かごドア閉鎖検出器１１と同様の構成である。 The car door closing detector 11 detects the closing of the car door 10 by detecting the contact between the door ends. In addition, the car door closing detector 11 has only a failure on the safe side (a fault that erroneously detects that the car door 10 is closed but opened). That is, it is not erroneously detected that the car door 10 is open but closed. Further, the landing door closing detectors 13a to 13c have the same configuration as the car door closing detector 11.
　第２のかごドアパネル１０ｂの上部の戸袋側端部には、検出片２９が取り付けられている。ドア桁２３には、検出片２９を検出する閉鎖センサ３０及び開放センサ３１が設けられている。第２のかごドアパネル１０ｂが全閉位置に移動すると、閉鎖センサ３０により検出片２９が検出される。また、第２のかごドアパネル１０ｂが全開位置に移動すると、開放センサ３１により検出片２９が検出される。このような検出片２９、閉鎖センサ３０及び開放センサ３１は、乗場ドア１２ａ～１２ｃにも設けられている。 A detection piece 29 is attached to the upper end portion of the second car door panel 10b. The door beam 23 is provided with a closing sensor 30 and an opening sensor 31 for detecting the detection piece 29. When the second car door panel 10 b moves to the fully closed position, the detection piece 29 is detected by the closing sensor 30. Further, when the second car door panel 10 b moves to the fully open position, the detection piece 29 is detected by the opening sensor 31. The detection piece 29, the closing sensor 30, and the opening sensor 31 are also provided on the landing doors 12a to 12c.
　かごドアパネル１０ａ，１０ｂの開閉は、ドア制御装置３２により制御される。ドア制御装置３２は、閉鎖センサ３０及び開放センサ３１からの信号に応じてドアモータの駆動を制御する。また、ドア制御装置３２は、閉鎖センサ３０及び開放センサ３１からの信号に基づいてかごドア１０及び乗場ドア１２ａ～１２ｃの開閉状態を判断する。この例では、図２の第２のドア閉鎖検出手段２２として、ドア制御装置３２を用いる。即ち、ドア制御装置３２は、かごドア１０及び乗場ドア１２ａ～１２ｃの開閉状態に関する情報を制動力解除許可手段２０に入力する。 Opening and closing of the car door panels 10a and 10b is controlled by the door control device 32. The door control device 32 controls the drive of the door motor in accordance with signals from the closing sensor 30 and the opening sensor 31. The door control device 32 determines the open / closed state of the car door 10 and the landing doors 12a to 12c based on signals from the closing sensor 30 and the opening sensor 31. In this example, a door control device 32 is used as the second door closing detection means 22 in FIG. That is, the door control device 32 inputs information regarding the open / closed state of the car door 10 and the landing doors 12a to 12c to the braking force release permission means 20.
　このようなエレベータ装置では、制動力解除許可手段２０が、第１及び第２のドア閉鎖検出手段２１，２２からの信号に基づいて、ブレーキ装置７の制動力の解除の可否を切り換えるので、かごドア閉鎖検出器１１及び乗場ドア閉鎖検出器１３ａ～１３ｃのいずれかが故障して、かごドア１０及び乗場ドア１２ａ～１２ｃのいずれかが開放していると誤検出されたとしても、第２のドア閉鎖検出手段２２によりかごドア１０及び乗場ドア１２ａ～１２ｃの全ての閉鎖が確認されれば、ブレーキ装置７の制動力の解除を可能にすることができる。そして、運転制御手段１４により、ブレーキ装置７を解放しつつ、かご１を目的階又は最寄り階に移動させることができる。従って、第１のドア閉鎖検出手段２１の故障によるかご１内への乗客の閉じ込めが発生した場合に、より短時間で乗客を救出することができる。 In such an elevator apparatus, the braking force release permission means 20 switches whether the braking force of the brake device 7 can be released based on the signals from the first and second door closing detection means 21 and 22. Even if one of the door closing detector 11 and the landing door closing detectors 13a to 13c breaks down and it is erroneously detected that one of the car door 10 and the landing doors 12a to 12c is open, the second If it is confirmed by the door closing detection means 22 that the car door 10 and the landing doors 12a to 12c are all closed, the braking force of the brake device 7 can be released. Then, the car 1 can be moved to the destination floor or the nearest floor while the brake device 7 is released by the operation control means 14. Therefore, when the passenger is trapped in the car 1 due to the failure of the first door closing detection means 21, the passenger can be rescued in a shorter time.
　なお、第１のドア閉鎖検出手段２１の故障が検出された場合には、制動力解除許可手段２０から、直接又は運転制御手段１４を介して、故障検出信号を外部に送信するのが好適である。
　また、第１のドア閉鎖検出手段２１の故障が検出された場合には、かご１を目的階又は最寄り階に安全に停止させた後、第１のドア閉鎖検出手段２１が復旧が確認されるまでエレベータ装置の運転を休止させるのが好適である。 In addition, when a failure of the first door closing detection unit 21 is detected, it is preferable to transmit a failure detection signal from the braking force release permission unit 20 directly or via the operation control unit 14. is there.
When a failure of the first door closing detection means 21 is detected, the car 1 is safely stopped at the destination floor or the nearest floor, and then the first door closing detection means 21 is confirmed to be restored. It is preferable to stop the operation of the elevator apparatus.
　実施の形態２．
　次に、図５はこの発明の実施の形態２によるエレベータ装置の要部を示す回路図である。図において、第１のドア閉鎖検出手段２１は、電磁継電器のコイル部１６ａと電源１８ａとの間に接続されている。具体的には、かごドア閉鎖検出器１１及び乗場ドア閉鎖検出器１３ａ～１３ｃのスイッチ群が、電磁継電器のコイル部１６ａと電源１８ａとの間に直列に接続されている。 Embodiment 2. FIG.
5 is a circuit diagram showing a main part of an elevator apparatus according to Embodiment 2 of the present invention. In the figure, the first door closing detection means 21 is connected between the coil portion 16a of the electromagnetic relay and the power source 18a. Specifically, the switch group of the car door closing detector 11 and the landing door closing detectors 13a to 13c are connected in series between the coil portion 16a of the electromagnetic relay and the power source 18a.
　従って、かごドア閉鎖検出器１１及び乗場ドア閉鎖検出器１３ａ～１３ｃの少なくとも１つのスイッチが開放されると、ブレーキコイル接点部１６ｂが直ちに開放される。また、制動力解除許可手段２０は、かごドア閉鎖検出器１１及び乗場ドア閉鎖検出器１３ａ～１３ｃの少なくとも１つのスイッチが開放されているかどうかを検出可能である。 Therefore, when at least one switch of the car door closing detector 11 and the landing door closing detectors 13a to 13c is opened, the brake coil contact portion 16b is immediately opened. Further, the braking force release permission means 20 can detect whether or not at least one of the car door closing detector 11 and the landing door closing detectors 13a to 13c is opened.
　ブレーキコイル７ａは、電源１５ａ及び接地部１５ｂとは別に、電源３３ａ及び接地部３３ｂに接続されている。これにより、ブレーキコイル接点部１６ｂが開放されているときでも、電源３３ａによりブレーキコイル７ａへの通電が可能となっている。 The brake coil 7a is connected to the power supply 33a and the grounding part 33b separately from the power supply 15a and the grounding part 15b. Thereby, even when the brake coil contact portion 16b is opened, the power supply 33a can energize the brake coil 7a.
　ブレーキコイル７ａと接地部３３ｂとの間には、ブレーキコイル７ａへの通電を制御するブレーキコイル制御スイッチ３４が設けられている。ブレーキコイル制御スイッチ３４としては、例えば半導体スイッチが用いられている。 A brake coil control switch 34 for controlling energization to the brake coil 7a is provided between the brake coil 7a and the grounding portion 33b. As the brake coil control switch 34, for example, a semiconductor switch is used.
　ブレーキコイル制御スイッチ３４のオン・オフは、制動力解除許可手段２０により制御される。ブレーキコイル制御スイッチ３４は、通常時はオフにされている。制動力解除許可手段２０は、少なくとも１つのエレベータドアが開放されていることが第１のドア閉鎖検出手段２１により検出されているときに、第２のドア閉鎖検出手段２２により全てのエレベータドアが閉鎖状態であることが検出されている場合、ブレーキコイル制御スイッチ３４をオンにしてブレーキ装置７の制動力の解除を可能とする。他の構成は、実施の形態１と同様である。 The on / off state of the brake coil control switch 34 is controlled by the braking force release permission means 20. The brake coil control switch 34 is normally turned off. The braking force release permission means 20 is configured such that when the first door closing detection means 21 detects that at least one elevator door is open, all the elevator doors are detected by the second door closing detection means 22. When it is detected that the vehicle is in the closed state, the brake coil control switch 34 is turned on to enable the braking force of the brake device 7 to be released. Other configurations are the same as those in the first embodiment.
　このようなエレベータ装置では、かごドア閉鎖検出器１１及び乗場ドア閉鎖検出器１３ａ～１３ｃのいずれかの故障により、ブレーキコイル接点部１６ｂが開放された場合でも、第２のドア閉鎖検出手段２２によりかごドア１０及び乗場ドア１２ａ～１２ｃの全ての閉鎖が確認されれば、ブレーキコイル制御スイッチ３４により別の電路を接続し、ブレーキ装置７の制動力の解除を可能にすることができる。そして、制動力解除許可手段２０によりブレーキ装置７を解放しつつ、運転制御手段１４によりかご１を目的階又は最寄り階に移動させることができる。従って、第１のドア閉鎖検出手段２１の故障によるかご１内への乗客の閉じ込めが発生した場合に、より短時間で乗客を救出することができる。 In such an elevator apparatus, even if the brake coil contact portion 16b is opened due to a failure of one of the car door closing detector 11 and the landing door closing detectors 13a to 13c, the second door closing detecting means 22 If it is confirmed that all of the car door 10 and the landing doors 12a to 12c are closed, another electric circuit can be connected by the brake coil control switch 34, and the braking force of the brake device 7 can be released. Then, the car 1 can be moved to the destination floor or the nearest floor by the operation control means 14 while releasing the brake device 7 by the braking force release permission means 20. Therefore, when the passenger is trapped in the car 1 due to the failure of the first door closing detection means 21, the passenger can be rescued in a shorter time.
　また、実施の形態２では、ブレーキコイル接点部１６ｂが開閉する電路とは別の電路を制動力解除許可手段２０により接続してブレーキ装置７の制動力の解除を可能とするので、運転制御手段１４やブレーキコイル制御スイッチ１７が故障した場合にもブレーキ装置７の制動力を解除することができる。 Further, in the second embodiment, an electric circuit different from the electric circuit that opens and closes the brake coil contact portion 16b is connected by the braking force release permission means 20 so that the braking force of the brake device 7 can be released. Even when 14 or the brake coil control switch 17 breaks down, the braking force of the brake device 7 can be released.
　なお、実施の形態１、２では、第１及び第２のドア閉鎖検出手段２１，２２を用いたが、同一のエレベータドアの閉鎖をそれぞれ別々に（独立して）検出する３組以上のドア閉鎖検出手段を用いてもよい。
　例えば、エレベータドアの閉鎖を第１及び第２のドア閉鎖検出手段２１，２２とは別に検出する第３のドア閉鎖検出手段を用いてもよい。第３のドア閉鎖検出手段としては、例えば、エレベータドアを撮影するカメラ監視装置を用いることができる。
　また、第３のドア閉鎖検出手段を用いる場合、制動力解除許可手段２０は、少なくとも１つのエレベータドアが開放されていることが第１のドア閉鎖検出手段２１により検出されているときに、第２のドア閉鎖検出手段２２及び第３のドア閉鎖検出手段により全てのエレベータドアが閉鎖状態であることが検出されている場合、ブレーキ装置７の制動力の解除を可能とする。このように、第２のドア閉鎖検出手段２２だけでなく、第３のドア閉鎖検出手段からの情報も確認することにより、信頼性をより向上させることができる。 In the first and second embodiments, the first and second door closing detection means 21 and 22 are used. However, three or more sets of doors that detect the closing of the same elevator door separately (independently). Closure detection means may be used.
For example, third door closing detection means for detecting the closing of the elevator door separately from the first and second door closing detection means 21 and 22 may be used. As the third door closing detection means, for example, a camera monitoring device that photographs an elevator door can be used.
Further, when the third door closing detection means is used, the braking force release permission means 20 is configured such that when the first door closing detection means 21 detects that at least one elevator door is open, When it is detected by the second door closing detection means 22 and the third door closing detection means that all the elevator doors are closed, the braking force of the brake device 7 can be released. Thus, by checking not only the second door closing detection means 22 but also the information from the third door closing detection means, the reliability can be further improved.
　実施の形態３．
　次に、図６はこの発明の実施の形態３によるエレベータ装置の要部を示す回路図である。図において、運転制御手段１４及び制動力解除許可手段２０は、それぞれ通信手段を有しており、通信回線を介して管理装置３５と相互に通信可能となっている。管理装置３５は、例えば遠隔の集中管理センタに設置されている。 Embodiment 3 FIG.
Next, FIG. 6 is a circuit diagram showing a main part of an elevator apparatus according to Embodiment 3 of the present invention. In the figure, each of the operation control means 14 and the braking force release permission means 20 has a communication means, and can communicate with the management device 35 via a communication line. The management device 35 is installed in a remote central management center, for example.
　運転制御手段１４は、かご１の状態に関する情報を管理装置３５に送信する。また、第１のドア閉鎖検出手段２１の故障が検出された場合、運転制御手段１４は、管理装置３５からの指令信号に基づいてかご１を運転する。 The operation control means 14 transmits information on the state of the car 1 to the management device 35. Further, when a failure of the first door closing detection unit 21 is detected, the operation control unit 14 operates the car 1 based on a command signal from the management device 35.
　制動力解除許可手段２０は、エレベータドアの開閉状態に関する情報を管理装置３５に送信する。また、第１のドア閉鎖検出手段２１の故障が検出された場合、制動力解除許可手段２０は、管理装置３５からの指令信号に基づいて、ブレーキ装置７の制動力の解除の可否を切り換える。 The braking force release permission means 20 transmits information related to the opening / closing state of the elevator door to the management device 35. When a failure of the first door closing detection unit 21 is detected, the braking force release permission unit 20 switches whether the braking force of the brake device 7 can be released based on a command signal from the management device 35.
　管理装置３５における指令信号の入力は、管理人が手動で行うか、又は管理装置３５内のコンピュータによる判断処理により自動的に行われる。他の構成は、実施の形態１と同様である。 The input of the command signal in the management device 35 is performed manually by an administrator or automatically by a judgment process by a computer in the management device 35. Other configurations are the same as those in the first embodiment.
　このようなエレベータ装置では、第１のドア閉鎖検出手段２１の故障が検出された場合に、管理装置３５からの指令信号を待って、制動力の解除を可能にするとともに、かご１を走行させるので、エレベータドアが閉鎖されているかどうか、かご１を走行させてもよいかどうかを、より確実に判断することができ、信頼性を向上させることができる。 In such an elevator apparatus, when a failure of the first door closing detection means 21 is detected, the elevator apparatus can wait for a command signal from the management apparatus 35 to release the braking force and run the car 1. Therefore, it is possible to more reliably determine whether the elevator door is closed and whether the car 1 may be driven, and the reliability can be improved.
　実施の形態４．
　次に、図７はこの発明の実施の形態４によるエレベータ装置の要部を示す回路図である。図において、運転制御手段１４及び制動力解除許可手段２０は、それぞれ通信手段を有しており、通信回線を介して管理装置３５と相互に通信可能となっている。管理装置３５は、例えば遠隔の集中管理センタに設置されている。 Embodiment 4 FIG.
Next, FIG. 7 is a circuit diagram showing a main part of an elevator apparatus according to Embodiment 4 of the present invention. In the figure, each of the operation control means 14 and the braking force release permission means 20 has a communication means, and can communicate with the management device 35 via a communication line. The management device 35 is installed in a remote central management center, for example.
　運転制御手段１４は、かご１の状態に関する情報を管理装置３５に送信する。また、第１のドア閉鎖検出手段２１の故障が検出された場合、運転制御手段１４は、管理装置３５からの指令信号に基づいてかご１を運転する。 The operation control means 14 transmits information on the state of the car 1 to the management device 35. Further, when a failure of the first door closing detection unit 21 is detected, the operation control unit 14 operates the car 1 based on a command signal from the management device 35.
　制動力解除許可手段２０は、エレベータドアの開閉状態に関する情報を管理装置３５に送信する。また、第１のドア閉鎖検出手段２１の故障が検出された場合、制動力解除許可手段２０は、管理装置３５からの指令信号に基づいて、ブレーキ装置７の制動力の解除の可否を切り換える。 The braking force release permission means 20 transmits information related to the opening / closing state of the elevator door to the management device 35. When a failure of the first door closing detection unit 21 is detected, the braking force release permission unit 20 switches whether the braking force of the brake device 7 can be released based on a command signal from the management device 35.
　具体的には、制動力解除許可手段２０は、ブレーキ装置７の制動力を解除するための電路が第１のドア閉鎖検出手段２１により遮断されているときに、管理装置３５からの指令信号に応じて、ブレーキ装置７の制動力を解除するための別の電路を接続してブレーキ装置７の制動力の解除を可能とする。 Specifically, the braking force release permission means 20 outputs a command signal from the management device 35 when the electric circuit for releasing the braking force of the brake device 7 is interrupted by the first door closing detection means 21. Accordingly, another electric circuit for releasing the braking force of the brake device 7 is connected to enable the braking force of the brake device 7 to be released.
　管理装置３５における指令信号の入力は、管理人が手動で行うか、又は管理装置３５内のコンピュータによる判断処理により自動的に行われる。他の構成は、実施の形態２と同様である。 The input of the command signal in the management device 35 is performed manually by an administrator or automatically by a judgment process by a computer in the management device 35. Other configurations are the same as those in the second embodiment.
　このようなエレベータ装置では、第１のドア閉鎖検出手段２１の故障が検出された場合に、管理装置３５からの指令信号を待って、制動力の解除を可能にするとともに、かご１を走行させるので、エレベータドアが閉鎖されているかどうか、かご１を走行させてもよいかどうかを、より確実に判断することができ、信頼性を向上させることができる。 In such an elevator apparatus, when a failure of the first door closing detection means 21 is detected, the elevator apparatus can wait for a command signal from the management apparatus 35 to release the braking force and run the car 1. Therefore, it is possible to more reliably determine whether the elevator door is closed and whether the car 1 may be driven, and the reliability can be improved.
　なお、実施の形態３、４では、第１及び第２のドア閉鎖検出手段２１，２２を用いたが、同一のエレベータドアの閉鎖をそれぞれ別々に（独立して）検出する３組以上のドア閉鎖検出手段を用いてもよい。 In the third and fourth embodiments, the first and second door closing detection means 21 and 22 are used.
