Description

本発明は、シート状、スラット状又はパネル状のカーテンなどの開閉体を用いて建物内部の通路やホール空間などを自動的に閉鎖することのできる開閉体装置に関する。   The present invention relates to an opening / closing body device capable of automatically closing a passage or a hall space inside a building using an opening / closing body such as a sheet-like, slat-like or panel-like curtain.

従来、住宅、ビル、工場、倉庫、車庫などの建物を含む構築・構造物の開口部に設置されるシャッターカーテンなどの開閉体装置は、開口部の上側に設置され、降下方向へ移動することによってその開口部を閉鎖するものである。このような開閉体装置としては、シャッターの上昇動作および下降動作を電動機で行なうように構成された電動シャッター装置がある。この種のシャッター装置は、設置された建物や近隣で発生した火災や停電等の非常時に、他の建物などへの延焼や損傷等を最小限に抑えるため、開放状態にある開閉体を自動的に閉鎖させている。このとき、開閉体を電動で閉鎖させるものや開閉体自体の自重で閉鎖させるものが存在する。   Conventionally, opening / closing body devices such as shutter curtains installed at the opening of construction and structures including buildings such as houses, buildings, factories, warehouses, garages, etc. are installed above the opening and move in the descending direction. To close the opening. As such an opening / closing body device, there is an electric shutter device configured to perform an ascending operation and a descending operation of a shutter with an electric motor. This type of shutter device automatically opens and closes open / closed bodies in order to minimize the spread of fire and damage to other buildings in the event of an emergency such as a fire or power outage that has occurred in a building or neighborhood. Closed. At this time, there are those that electrically close the opening / closing body and those that close the opening / closing body by its own weight.

電動で開閉体を上昇下降制御できる電動シャッター装置では、開閉体の開閉動作をボタンスイッチなどを用いて手動で操作することのできる開閉機に制動装置が備えられおり、通常はこの制動装置により開閉機の自由な回転を規制して開閉体を開放状態に保持しており、非常時にはこの制動装置によるブレーキ状態を解除して、開閉体を自重降下させることができるように構成されている。このような開閉体装置については、特許文献1に示すものが知られている。   In an electric shutter device that can control the lifting and lowering of the opening / closing body electrically, a braking device is provided in an opening / closing device that can manually operate the opening / closing operation of the opening / closing member using a button switch or the like. The opening and closing body is held in an open state by restricting the free rotation of the machine. In an emergency, the brake state by the braking device is released and the opening and closing body can be lowered by its own weight. As such an opening / closing body device, the one disclosed in Patent Document 1 is known.

特開平11−324539号公報Japanese Patent Laid-Open No. 11-324539

図1は、電動機を備えた開閉体装置であって自重降下によってこのような防火区画を形成することのできる従来の開閉体装置の概略構成を示す図である。この開閉体装置は、通常は開閉機1がシャッターカーテン4を図示しない巻取軸に巻き取るなどして開口部の周縁部の上部に設けられた収納部に収納するものである。なお、シャッターカーテン4を巻き取らずに収納部に収納して開放状態とするものもある。このような開閉体装置においては、シャッターカーテン4の閉鎖は、その自重で降下して行なう場合もあれば、電動で降下させる場合もある。また、この開閉体装置は、シャッターカーテン4の巻取軸に動力源となる開閉機1と、この開閉機1による回転を制動するブレーキ機構2とを備えている。開閉機1の駆動軸の一端側には動力伝達手段(図示せず)が設けられ、この駆動軸の回転力が巻取軸に伝達されるように構成されている。一方、駆動軸の他端側にはブレーキ機構2からの制動力を受けるように略円盤状のブレーキシューが設けられている。   FIG. 1 is a diagram showing a schematic configuration of a conventional open / close body device that is an open / close body device equipped with an electric motor and that can form such a fire-protection section by its own weight drop. In this opening / closing body device, the opening / closing device 1 is usually stored in a storage portion provided at the upper part of the peripheral edge of the opening by winding the shutter curtain 4 around a winding shaft (not shown). In some cases, the shutter curtain 4 is stored in the storage unit without being wound up and is opened. In such an opening / closing body device, the shutter curtain 4 may be closed by its own weight or may be lowered electrically. In addition, the opening / closing body device includes an opening / closing machine 1 serving as a power source on a winding shaft of the shutter curtain 4 and a brake mechanism 2 that brakes rotation by the opening / closing machine 1. A power transmission means (not shown) is provided on one end side of the drive shaft of the opening / closing machine 1, and the rotational force of the drive shaft is transmitted to the take-up shaft. On the other hand, a substantially disc-shaped brake shoe is provided on the other end side of the drive shaft so as to receive a braking force from the brake mechanism 2.

ブレーキ機構2は、開閉機1の駆動軸に対し略直線状に並ぶように配置されたブレーキ軸と、このブレーキ軸に固定され、ブレーキシューに対し離脱可能に当接したブレーキドラムと、このブレーキドラムをブレーキシューへ付勢するコイルスプリングと、このコイルスプリングの付勢力に抗してブレーキドラムを吸引する電磁ソレノイドと、このコイルスプリングの付勢力に抗して手動でブレーキドラムをブレーキシューから離間させるためのレバー部材とを備えている。すなわち、ブレーキ機構2の制動状態を解除する方法として、電磁ソレノイドを用いた電気的解除方法とレバー部材を用いた機械的解除方法を備えている。   The brake mechanism 2 includes a brake shaft arranged so as to be aligned substantially linearly with respect to the drive shaft of the switch 1, a brake drum fixed to the brake shaft and detachably contacting the brake shoe, and the brake A coil spring that urges the drum to the brake shoe, an electromagnetic solenoid that attracts the brake drum against the urging force of the coil spring, and a brake drum that is manually separated from the brake shoe against the urging force of the coil spring And a lever member. That is, as a method for releasing the braking state of the brake mechanism 2, an electrical release method using an electromagnetic solenoid and a mechanical release method using a lever member are provided.

通常、シャッターカーテン4の開放状態はブレーキ機構2で開閉機1の駆動軸を機械的にロックすることによって維持されている。このような開放状態にある開閉体装置が火災発生時に感知器15からのワンショット(一般的には数秒〜数十秒の長さで単発発報)又は長時間継続的発報の防災信号BSを受けると、連動制御器5からの電力供給により、自動閉鎖装置3が初期状態(復旧状態)から作動状態に移行して内蔵の図示しない動作手段(例えばモーター,スプリング等)を作動させてブレーキ機構2のレバー部材を揺動させて、ブレーキ機構2を制動状態から解除状態(作動状態)にする。これによって、ブレーキシューからブレーキドラムが強制的に外され、開閉機1の駆動軸が自由回転可能な状態となり、巻取軸も自由回転可能な状態となり、巻取軸に巻かれて全開状態にあったシャッターカーテン4は、ガイドレール11に沿って自重により自然降下により収納部から繰り出されて閉鎖動作を開始し、開口部を閉鎖し(仕切り)、所定の防火区画を形成するようになっている。一方、開閉機1を用いてシャッターカーテン4を開閉制御する場合には、シャッター制御盤6によって電磁ソレノイドに通電してブレーキ機構2の制動状態を解除し、駆動軸を回転自在な状態にしている。   Normally, the open state of the shutter curtain 4 is maintained by mechanically locking the drive shaft of the switch 1 with the brake mechanism 2. When the open / close body device in such an open state is in a fire, the disaster prevention signal BS of one-shot from the sensor 15 (generally, a single alert with a length of several seconds to several tens of seconds) or a long-time continuous alert. In response to the power supply from the interlock controller 5, the automatic closing device 3 shifts from the initial state (restored state) to the operating state, and operates a built-in operating means (not shown) (for example, a motor, a spring, etc.) to brake. The lever member of the mechanism 2 is swung to bring the brake mechanism 2 from the braking state to the released state (operating state). As a result, the brake drum is forcibly removed from the brake shoe, the drive shaft of the opening / closing machine 1 is in a freely rotatable state, the winding shaft is also in a freely rotatable state, is wound around the winding shaft, and is fully opened. The existing shutter curtain 4 is drawn out from the storage portion by natural descent along the guide rail 11 due to its own weight, starts a closing operation, closes (partitions) the opening, and forms a predetermined fire prevention section. Yes. On the other hand, when the opening / closing control of the shutter curtain 4 using the opening / closing device 1 is performed, the electromagnetic solenoid is energized by the shutter control panel 6 to release the braking state of the brake mechanism 2 so that the drive shaft is rotatable. .

電動開閉用操作部7は、シャッター制御盤6を介して、主にシャッター電動開閉駆動用の開閉機1を操作するためのシャッターカーテン開閉停の指示に対応した平常時操作用の入力スイッチ(開ボタン7A、閉ボタン7C、停止ボタン7Bを含む押しボタンスイッチを備えたものである。なお、防災信号BSの受信を再現する非常用シャッター閉鎖ボタンである作動ボタンや制御器5、自動閉鎖装置3のリセット用の復旧ボタンなどを必要に応じて備えることもある。また、シャッター制御盤6は、停止ボタン7Bが入力されている間は、開ボタン7Aや閉7Bの操作は無効として制御されるようになっている。   The electric opening / closing operation unit 7 is operated through a shutter control panel 6 to operate a normal operation input switch (open) corresponding to a shutter curtain opening / closing instruction mainly for operating the shutter electric opening / closing driving switch 1. A push button switch including a button 7A, a close button 7C, and a stop button 7B is provided, and an operation button or controller 5 that is an emergency shutter closing button that reproduces reception of the disaster prevention signal BS, and an automatic closing device 3 The shutter control panel 6 is controlled to invalidate the operation of the open button 7A and the close 7B while the stop button 7B is being input. It is like that.

図1の開閉体装置においては、障害物感知装置は図示していないが、例えば本願出願人が先に出願した特開2008−223459号公報に記載のものやこれに類似した構成のものが適用されている。この障害物感知装置は、開閉体本体の閉鎖動作中に、開閉体本体の閉鎖方向端部に接続された可動座板が障害物に接触した場合、可動座板が開閉体本体に相対して開放方向へ移動し、その可動座板の移動に機械的に連動して、ブレーキ機構2を解除状態から制動状態にするものである。従って、この障害物感知装置を用いることによって、電源不良等の影響を受け難い簡素構造でもって、開閉体の閉鎖動作を障害物との接触により停止することができる。   Although the obstacle sensing device is not shown in the opening / closing body device of FIG. 1, for example, the one described in Japanese Patent Application Laid-Open No. 2008-223459 filed earlier by the applicant of the present application or a similar configuration is applied. Has been. When the movable seat plate connected to the end in the closing direction of the opening / closing body is in contact with the obstacle during the closing operation of the opening / closing body, the obstacle sensing device is opposed to the opening / closing body. The brake mechanism 2 is moved from the released state to the braked state mechanically in conjunction with the movement of the movable seat plate. Therefore, by using this obstacle sensing device, the closing operation of the opening / closing body can be stopped by contact with the obstacle with a simple structure that is not easily affected by a power failure or the like.

図2は、図1の開閉機、ブレーキ機構、自動閉鎖装置、連動制御器及びシャッター制御盤などの接続関係を模式的に示した図である。図2において、図1と同じ構成のものには同一の符号が付してあるので、その説明は省略する。図2に示すように、連動制御器5は、防災信号BSを受けることによって、端子DC−D間の自動閉鎖装置3内のソレノイド(DC SOL)に直流24V信号を供給し、ブレーキ機構2を制動状態から解除状態にして、シャッターカーテン4を自重降下させる。自動閉鎖装置3は、ソレノイド(DC SOL)に直流24V信号を供給されると、内蔵の図示しない蓄圧されたスプリングが解放され、そのスプリングによりブレーキ機構2を制動状態から解除状態にする機構を備えている。ブレーキ機構2が制動状態から解除状態になると、マイクロスイッチMS1によって端子DC−DA間が接続し、ブレーキ機構2が解除されたことが連動制御器5に伝達される。一方、マイクロスイッチMS2がオンして、復旧用電磁ソレノイド(AC SOL)が通電可能状態となる。この通電可能状態で電動開閉用操作部7の開ボタン7Aが押し操作されると、復旧用電磁ソレノイド(AC SOL)が動作し、ブレーキ機構2が制動状態から解除状態になり、開閉機1によってシャッターカーテン4が開動作するようになる。自動閉鎖装置3は、復旧用電磁ソレノイドに通電されると、その動力によりブレーキ機構2を解除状態にした状態から解除状態にしない状態に戻すと共に、前述の自動閉鎖装置内のスプリングを蓄圧してロックする機構を備えている。   FIG. 2 is a diagram schematically showing a connection relationship among the switch, the brake mechanism, the automatic closing device, the interlock controller, the shutter control panel, and the like of FIG. In FIG. 2, since the same code | symbol is attached | subjected to the same structure as FIG. 1, the description is abbreviate | omitted. As shown in FIG. 2, the interlock controller 5 supplies a DC 24V signal to the solenoid (DC SOL) in the automatic closing device 3 between the terminals DC-D by receiving the disaster prevention signal BS, and the brake mechanism 2 is turned on. The shutter curtain 4 is lowered by its own weight from the braking state to the release state. The automatic closing device 3 is provided with a mechanism for releasing a built-in pressure-accumulated spring (not shown) when the solenoid (DC SOL) is supplied with a DC 24V signal, and for releasing the brake mechanism 2 from the braking state by the spring. ing. When the brake mechanism 2 is released from the braking state, the terminals DC and DA are connected by the microswitch MS1, and the interlock controller 5 is notified that the brake mechanism 2 has been released. On the other hand, the microswitch MS2 is turned on, and the recovery electromagnetic solenoid (AC SOL) becomes energized. When the open button 7A of the electric opening / closing operation unit 7 is pushed in this energized state, the recovery electromagnetic solenoid (AC SOL) is operated, and the brake mechanism 2 is released from the braking state. The shutter curtain 4 is opened. When the recovery electromagnetic solenoid is energized, the automatic closing device 3 returns the brake mechanism 2 from the released state to the non-released state by its power, and accumulates the spring in the automatic closing device. A locking mechanism is provided.

図1及び図2に示すような従来の防火シャッター装置の自動閉鎖装置3においては、連動制御器5から作動信号(直流24V信号)が出力され、一旦通電動作中になると、この作動信号が無くなっても、自重降下動作を継続し続ける(または自重降下動作を解消しない)ように構成されている。ところが、図2に示すように、自動閉鎖装置3の動作中(シャッターカーテン4の自重降下中及び障害物感知による停止中)に電動開閉用操作部7の開ボタン7Aが誤って押し操作されると、自動閉鎖装置3の復旧用電磁ソレノイド(AC SOL)に電流が流れ、自動閉鎖装置3を復旧(リセット、つまりブレーキ機構を解除状態とし作動状態を中止)させてしまうことが考えられる。自動閉鎖装置3が復旧すると、開閉機1によってシャッターカーテン4が開動作(上昇動作)するようになり、防火区画を形成することができなくなるという不具合が発生するおそれがあった。しかも、開動作後の停止時に自動閉鎖装置3が復旧しているためブレーキ装置2が通常時と同じく制動状態となり、防災信号BSの入力が終わっていれば、シャッターカーテン4の再閉鎖の動作が自動的に行なわれず、この不具合の担保もなされない。また、自動閉鎖装置3の動作中であって障害物感知による停止中に電動開閉用操作部7の閉ボタン7Cが誤って押し操作されると、シャッターカーテン4は障害物感知による停止中に関わらず開閉機1によってシャッターカーテン4が閉動作(下降動作)するという不具合が発生するおそれがあった。   In the conventional automatic closing device 3 of the fire shutter device as shown in FIG. 1 and FIG. 2, an operation signal (DC 24V signal) is output from the interlock controller 5, and once the energization operation is performed, this operation signal disappears. However, it is configured to continue the self-weight drop operation (or not to cancel the self-weight drop operation). However, as shown in FIG. 2, the open button 7 </ b> A of the electric opening / closing operation unit 7 is erroneously pushed and operated while the automatic closing device 3 is in operation (while the shutter curtain 4 is lowered due to its own weight and when it is detected by obstacle detection). Then, it is conceivable that a current flows through the recovery electromagnetic solenoid (AC SOL) of the automatic closing device 3 to restore the automatic closing device 3 (reset, that is, release the brake mechanism and stop the operating state). When the automatic closing device 3 is restored, the shutter curtain 4 is opened (raised) by the opening / closing device 1, which may cause a problem that a fire prevention compartment cannot be formed. In addition, since the automatic closing device 3 is restored at the stop after the opening operation, the braking device 2 is in a braking state as in the normal state, and when the disaster prevention signal BS has been input, the reclosing operation of the shutter curtain 4 is performed. It is not done automatically and this defect is not guaranteed. In addition, if the close button 7C of the electric opening / closing operation unit 7 is erroneously pressed while the automatic closing device 3 is operating and is stopped due to obstacle detection, the shutter curtain 4 is not related to being stopped due to obstacle detection. There is a possibility that the shutter curtain 4 is closed (lowered) by the opening / closing device 1.

この発明は、上述の点に鑑みなされたものであり、開閉体の自重降下中に電動開閉用操作部の開スイッチ又は閉スイッチが入力された場合でも開スイッチ又は閉スイッチの入力に対応した動作を行なわないように構成された開閉体装置を提供することを目的とする。   The present invention has been made in view of the above points, and even when the open switch or the close switch of the electric opening / closing operation unit is input during the weight drop of the open / close body, the operation corresponds to the input of the open switch or the close switch. An object of the present invention is to provide an opening / closing body device configured not to perform the above.

本発明に係る開閉体装置の第1の特徴は、開口部を開閉するように前記開口部の周縁部に設けられた開閉体手段と、前記開閉体手段を自重で降下させて前記開口部を閉鎖する自動閉鎖手段と、開閉停スイッチの入力状態に応じて電動で前記開閉体手段の開閉停動作を制御する開閉体制御手段であって、前記自動閉鎖手段によって前記開閉体手段が自重降下中は前記開閉停スイッチの中の少なくとも開スイッチが入力されてもその入力を無効なものと処理する開閉体制御手段とを備えたことにある。   The first feature of the opening / closing body device according to the present invention is that the opening / closing body means provided at the peripheral edge of the opening so as to open / close the opening, and the opening / closing body means is lowered by its own weight to open the opening. An automatic closing means for closing and an opening / closing body control means for electrically controlling an opening / closing stop operation of the opening / closing body means according to an input state of the opening / closing switch, wherein the opening / closing body means is being lowered by its own weight. Is provided with an opening / closing body control means for processing an input that is invalid even if at least an open switch among the open / close switches is input.

開閉体手段は、ビル、住宅、工場、倉庫等の建物などの構造物における、出入口や窓部、あるいは内部の通路や空間などの開口部などを開閉移動するシャッターカーテンなどの開閉部材で構成され、災害発生時や閉店時などに防火・防煙・防水・防風・防犯などのために開口部を仕切るために収納部から繰り出される。開閉体手段が、例えばシャッターカーテンの場合には、建物などの開口部の周縁部の一つである上部に収納され、まぐさなどを通過してシャッターカーテンが下降し、開口部を閉鎖する。自動閉鎖手段は、防災信号や非常閉鎖信号を入力することによって、シャッターカーテンを自重降下させ、開口部を閉鎖する。自動閉鎖装置は、この防災信号又は非常閉鎖信号を入力し、一旦通電動作中になると、防災信号又は非常閉鎖信号が無くなっても、自重降下動作を保持できるように構成されている。この発明では、自動閉鎖手段によって開閉体手段が自重降下中は開閉停スイッチの中の少なくとも開スイッチが入力されてもその入力を無効としている。従って、自重降下中に誤って開スイッチが入力されたとしても、自重降下動作は維持され続けるようになり、開スイッチの入力の際の不具合の発生を無くすことが可能となる。   The opening / closing body means is composed of an opening / closing member such as a shutter curtain that opens and closes an entrance / exit, a window, or an opening of an internal passage or space in a structure such as a building, a house, a factory, or a warehouse. In the event of a disaster or when a store is closed, it is drawn out from the storage unit to partition the opening for fire prevention, smoke prevention, waterproofing, windproofing, crime prevention, etc. When the opening / closing body means is, for example, a shutter curtain, it is housed in an upper portion that is one of the peripheral portions of the opening of a building or the like, passes through a lintel or the like, and the shutter curtain descends to close the opening. The automatic closing means, by inputting a disaster prevention signal or an emergency closing signal, lowers the weight of the shutter curtain and closes the opening. The automatic closing device is configured such that once the disaster prevention signal or emergency closing signal is input and the energization operation is performed, the self-weight drop operation can be maintained even if the disaster prevention signal or emergency closing signal disappears. In the present invention, when the open / close body means is lowered by its own weight by the automatic closing means, the input is invalidated even if at least the open switch of the open / close switch is input. Therefore, even if an open switch is input by mistake during the weight drop, the weight drop operation continues to be maintained, and it is possible to eliminate the occurrence of problems when the open switch is input.

本発明に係る開閉体装置の第2の特徴は、前記第1の特徴に記載の開閉体装置において、前記開閉体手段が自重降下中は、b接点を開くことによって自重降下中であることを示す信号を出力する作動中信号出力手段と、前記開閉体手段によって前記開口部が全閉状態にある場合は、a接点を閉じることによって全閉状態であることを示す信号を出力する全閉信号出力手段とを備え、b接点で構成される停スイッチに電流を供給する配線に対して、前記作動中信号出力手段を直列に接続し、前記全閉信号出力手段を作動中信号出力手段に並列に接続したことにある。自動閉鎖手段が作動中の場合、作動中信号出力手段のb接点は開状態となり、全閉信号出力手段のa接点は開状態となるので、b接点で構成される停スイッチに電流を供給する配線は非接続状態となり、開スイッチ又は閉スイッチが入力されてもそれは無効なものとなり、開閉体手段の自重閉鎖動作は維持されることとなる。   A second feature of the switchgear device according to the present invention is that in the switchgear device according to the first feature, when the switchgear means is under its own weight drop, it is under its own weight drop by opening the b contact. An in-operation signal output means for outputting a signal indicating that, and when the opening portion is in a fully closed state by the opening / closing body means, a fully closed signal for outputting a signal indicating the fully closed state by closing the contact a Output signal means, and in-line signal output means connected in series to a wiring for supplying current to a stop switch composed of b contacts, and the fully closed signal output means in parallel with the signal output means in operation There is in being connected to. When the automatic closing means is in operation, the b contact of the operating signal output means is opened and the a contact of the fully closed signal output means is opened, so that a current is supplied to the stop switch constituted by the b contact. The wiring is disconnected, and even if an open switch or a closed switch is input, it becomes invalid, and the self-weight closing operation of the opening / closing member means is maintained.

本発明に係る開閉体装置の第3の特徴は、前記第2の特徴に記載の開閉体装置において、前記開閉体手段が自重降下中は、b接点を開くことによって自重降下中であることを示す信号を出力する作動中信号出力手段と、前記開閉体手段によって前記開口部が全閉状態にある場合は、a接点を閉じることによって全閉状態であることを示す信号を出力する全閉信号出力手段とを備え、b接点で構成される停スイッチに電流を供給し、a接点で構成される開スイッチの電流出力配線に対して、前記作動中信号出力手段を直列に接続し、前記全閉信号出力手段を作動中信号出力手段に並列に接続したことにある。自動閉鎖手段が作動中の場合、作動中信号出力手段のb接点は開状態となり、全閉信号出力手段のa接点は開状態となるので、a接点で構成される開スイッチの電流出力配線は非接続状態となり、開スイッチが入力されてもそれは無効なものとなり、開閉体手段の自重閉鎖動作は維持されることとなる。   A third feature of the switchgear device according to the present invention is that in the switchgear device according to the second feature, when the switchgear means is under its own weight drop, it is under its own weight drop by opening the b contact. An in-operation signal output means for outputting a signal indicating that, and when the opening portion is in a fully closed state by the opening / closing body means, a fully closed signal for outputting a signal indicating the fully closed state by closing the contact a Output means, supplying current to a stop switch constituted by b contacts, and connecting the operating signal output means in series to a current output wiring of an open switch constituted by a contacts, The closing signal output means is connected in parallel to the operating signal output means. When the automatic closing means is in operation, the b-contact of the operating signal output means is open and the a-contact of the fully-closed signal output means is open, so that the current output wiring of the open switch composed of the a contact is Even if an open switch is inputted, it becomes invalid, and the open / close body means's own weight closing operation is maintained.

本発明に係る開閉体装置の第4の特徴は、前記第2又は第3の特徴に記載の開閉体装置において、前記開閉体手段が自重降下することによって通電可能状態となった復旧用電磁ソレノイドに電流を供給する端子と前記開閉停スイッチの開スイッチからの電流を入力する入力端子とを接続したことにある。復旧用電磁ソレノイドは開スイッチからの電流を入力する入力端子に接続されているので、開スイッチが押し入力されても、復旧用電磁ソレノイドは動作することなく、自動閉鎖手段の復旧操作も無効となる。   According to a fourth feature of the switchgear device according to the present invention, in the switchgear device according to the second or third feature, the electromagnetic solenoid for recovery which is in a state where electricity can be applied when the switchgear means lowers its own weight. And a terminal for supplying current to the input / output terminal and an input terminal for inputting current from the open switch of the open / close switch. The recovery electromagnetic solenoid is connected to the input terminal that inputs the current from the open switch. Therefore, even if the open switch is pressed, the recovery electromagnetic solenoid does not operate and the recovery operation of the automatic closing means is invalid. Become.

本発明に係る開閉体装置の第5の特徴は、前記開閉体手段が自重降下中は、a接点を閉じることによって自重降下中であることを示す信号を出力する作動中信号出力手段と、前記開閉体手段によって前記開口部が全閉状態にある場合は、b接点を開くことによって全閉状態であることを示す信号を出力する全閉信号出力手段とを備え、a接点で構成される前記開閉停スイッチのコモン端子に電流を供給する配線と、前記停スイッチの電流出力端との間に前記作動中信号出力手段と前記全閉信号出力手段とを直列に接続したことにある。これは、作動中信号出力手段と全閉信号出力手段との直列接続を停スイッチに電流を供給する配線に直列に接続したものであり、自動閉鎖手段が作動中の場合に停スイッチが押し入力されたのと同じ状態として、開スイッチ又は閉スイッチが入力されてもそれを無効なものとし、開閉体手段の自重閉鎖動作を維持するようにしたものである。   A fifth feature of the opening / closing body device according to the present invention is that the open / close body means outputs an in-operation signal output means for outputting a signal indicating that the opening / closing body means is falling under its own weight by closing the contact a. And a fully-closed signal output means for outputting a signal indicating that the opening is in the fully closed state by opening the b contact when the opening is in the fully closed state by the opening / closing body means. The operating signal output means and the fully closed signal output means are connected in series between a wiring for supplying current to the common terminal of the open / close stop switch and the current output terminal of the stop switch. This is a series connection of the in-operation signal output means and the fully-closed signal output means connected in series with the wiring for supplying current to the stop switch. When the automatic closing means is in operation, the stop switch is pressed and input. In the same state as described above, even if an open switch or a close switch is input, it is invalidated, and the self-closing operation of the opening / closing body means is maintained.

本発明によれば、開閉体の自重降下中に電動開閉用操作部の開スイッチ又は閉スイッチが入力された場合でも開スイッチ又は閉スイッチの入力に対応した動作を行なわないようにできるという効果がある。   According to the present invention, even when the open switch or the close switch of the electric opening / closing operation unit is input during the weight drop of the open / close body, it is possible to prevent the operation corresponding to the input of the open switch or the close switch from being performed. is there.

電動機を備えた開閉体装置であって自重降下によってこのような防火区画を形成することのできる従来の開閉体装置の概略構成を示す図である。It is a figure which shows schematic structure of the conventional opening-closing body apparatus which is an opening-closing body apparatus provided with the electric motor, and can form such a fire prevention compartment by dead weight fall. 図1の開閉機、ブレーキ機構、自動閉鎖装置、連動制御器及びシャッター制御盤などの接続関係を模式的に示した図である。It is the figure which showed typically the connection relations, such as the switch of FIG. 1, a brake mechanism, an automatic closing device, an interlocking controller, and a shutter control panel. 本発明に係る開閉体装置の結線図の実施例を示す図である。It is a figure which shows the Example of the connection diagram of the opening / closing body apparatus which concerns on this invention. 本発明に係る開閉体装置の結線図の別の実施例を示す図である。It is a figure which shows another Example of the connection diagram of the opening / closing body apparatus which concerns on this invention. 本発明に係る開閉体装置の結線図のさらに別の実施例を示す図である。It is a figure which shows another Example of the connection diagram of the opening / closing body apparatus which concerns on this invention.

以下、添付図面に従って本発明に係る開閉体装置の一例としてシャッター装置について説明する。シャッター装置は、短冊板状のスラットを多数連結してなるシャッターカーテンを、建物開口部の上方に巻回状態で収納し、巻き戻されながら繰り出されることで建物開口部を閉鎖する。本発明に係るシャッター装置の構成は、図1と同じなので、その説明は省略する。図3は、本発明に係る開閉体装置の結線図の実施例を示す図である。図3において、図2と同じ構成のものには同一の符号が付してあるので、その説明は省略する。   Hereinafter, a shutter device will be described as an example of an opening / closing body device according to the present invention with reference to the accompanying drawings. The shutter device stores a shutter curtain formed by connecting a large number of strip-like slats in a wound state above a building opening, and closes the building opening by being drawn out while being rewound. The configuration of the shutter device according to the present invention is the same as that shown in FIG. FIG. 3 is a diagram showing an example of a connection diagram of the opening / closing body device according to the present invention. In FIG. 3, since the same code | symbol is attached | subjected to the thing of the same structure as FIG. 2, the description is abbreviate | omitted.

この実施の形態に係る開閉体装置は、図3に示すように、シャッター制御盤6の端子P3と電動開閉用操作部7の停止ボタン7Bの端子との間に自動閉鎖装置31の作動中信号を出力するb接点32を直列に接続し、さらにこのb接点32に対してシャッターカーテン4の全閉信号を出力するa接点33を並列に接続している。   As shown in FIG. 3, the opening / closing body device according to this embodiment is a signal indicating that the automatic closing device 31 is operating between the terminal P <b> 3 of the shutter control panel 6 and the terminal of the stop button 7 </ b> B of the electric opening / closing operation unit 7. Are connected in series, and an a contact 33 for outputting a fully closed signal of the shutter curtain 4 is connected in parallel to the b contact 32.

連動制御器5は、ワンショット(一般的には数秒〜数十秒の長さで単発発報)又は長時間継続的発報の防災信号BSを受けることによって、端子DC−D間の自動閉鎖装置31内のソレノイド(DC SOL)に直流24V信号を供給し、ブレーキ機構2を制動状態から解除状態にして、シャッターカーテン4を自重降下させる。ブレーキ機構2が制動状態から解除状態になると、これに連動してマイクロスイッチMS1によって連動制御器5の端子DC−DA間が接続され、ブレーキ機構2が解除されたことが連動制御器5に伝達される。これとほぼ同時に、マイクロスイッチMS2がオンして、復旧用電磁ソレノイド(AC SOL)が通電可能状態となる。   The interlock controller 5 automatically closes between the terminals DC-D by receiving a disaster prevention signal BS of one shot (generally a single alert with a length of several seconds to several tens of seconds) or a continuous alert for a long time. A DC 24V signal is supplied to a solenoid (DC SOL) in the device 31 to bring the brake mechanism 2 from the braking state to the released state, and the shutter curtain 4 is lowered by its own weight. When the brake mechanism 2 is released from the braking state, the terminal DC-DA of the interlock controller 5 is connected by the micro switch MS1 in conjunction with this, and the release of the brake mechanism 2 is transmitted to the interlock controller 5. Is done. At substantially the same time, the micro switch MS2 is turned on, and the recovery electromagnetic solenoid (AC SOL) is ready to be energized.

復旧用電磁ソレノイド(AC SOL)が通電可能状態となった後に、電動開閉用操作部7の開ボタン7A又は閉ボタン7Cが押し操作された場合、自動閉鎖装置31は作動中にあるので、作動中信号を出力するb接点32は開状態にあり、シャッターカーテン4は未だ全閉していない閉動作中なので全閉信号を出力するa接点33も開状態にあり、b接点で構成される停ボタン7Bに電流を供給する配線は非接続状態となる。従って、a接点で構成される電動開閉用操作部7の開ボタン7A又は閉ボタン7Cが操作されても非通電のまま変わらずそれは無効なものとなり、自動閉鎖装置31はシャッターカーテン4の自重閉鎖を維持することとなる。また、電動開閉用操作部7の開ボタン7Aが押し操作されても、復旧用電磁ソレノイド(AC SOL)は動作することなく、自動閉鎖装置31の復旧操作も無効となる。一方、シャッターカーテン4が全閉すると、全閉信号を出力するa接点33が閉状態になるので、電動開閉用操作部7の停ボタン7Bに電流が供給され、開ボタン7A又は閉ボタン7Cが有効となり、開ボタン7Aが押し操作されるとシャッターカーテン4は開動作するようになり、また、復旧用電磁ソレノイド(AC SOL)も動作し、自動閉鎖装置31の復旧操作が可能となる。   If the open button 7A or the close button 7C of the electric opening / closing operation unit 7 is pushed after the recovery electromagnetic solenoid (AC SOL) is ready to be energized, the automatic closing device 31 is in operation. The b contact 32 for outputting the intermediate signal is in the open state, and since the shutter curtain 4 is not yet fully closed, the a contact 33 for outputting the fully closed signal is also in the open state, and the stop composed of the b contact is provided. The wiring for supplying current to the button 7B is disconnected. Accordingly, even if the open button 7A or the close button 7C of the electric opening / closing operation unit 7 constituted by the contact a is operated, it remains inactive and becomes invalid, and the automatic closing device 31 closes the shutter curtain 4 with its own weight. Will be maintained. Further, even when the open button 7A of the electric opening / closing operation unit 7 is pressed, the restoration electromagnetic solenoid (AC SOL) does not operate, and the restoration operation of the automatic closing device 31 becomes invalid. On the other hand, when the shutter curtain 4 is fully closed, the contact a 33 that outputs a fully closed signal is closed, so that a current is supplied to the stop button 7B of the electric opening / closing operation unit 7, and the open button 7A or the close button 7C is When the opening button 7A is pushed and operated, the shutter curtain 4 opens, and the recovery electromagnetic solenoid (AC SOL) also operates, so that the automatic closing device 31 can be recovered.

図4は、本発明に係る開閉体装置の結線図の別の実施例を示す図である。図4において、図3と同じ構成のものには同一の符号が付してあるので、その説明は省略する。図4の実施例が図3のものと異なる点は、電動開閉用操作部71の開ボタン7A、停ボタン7B及び閉ボタン7Cがそれぞれa接点で構成され、電動開閉用操作部71に対してシャッター制御盤61の端子P1から電動開閉用操作部71のコモン端子に電流が供給され、復旧用電磁ソレノイド(AC SOL)がシャッター制御盤61に端子P5に接続され、自動閉鎖装置34の作動中信号を出力するa接点35とシャッターカーテン4の全閉信号を出力するb接点36とが直列に接続され、作動中信号を出力するa接点35が電動開閉用操作部71の停ボタン7B側に、全閉信号を出力するb接点36がシャッター制御盤61の端子P1(電動開閉用操作部71のコモン端子)に接続されている点である。   FIG. 4 is a diagram showing another embodiment of the connection diagram of the opening / closing device according to the present invention. 4, the same components as those in FIG. 3 are denoted by the same reference numerals, and the description thereof is omitted. 4 differs from that of FIG. 3 in that the open button 7A, the stop button 7B, and the close button 7C of the electric opening / closing operation unit 71 are each configured as a contact, A current is supplied from the terminal P1 of the shutter control panel 61 to the common terminal of the electric opening / closing operation unit 71, and a recovery electromagnetic solenoid (AC SOL) is connected to the terminal P5 of the shutter control panel 61, and the automatic closing device 34 is in operation. The a contact 35 that outputs a signal and the b contact 36 that outputs a fully closed signal of the shutter curtain 4 are connected in series, and the a contact 35 that outputs an operating signal is connected to the stop button 7B side of the electric opening / closing operation unit 71. The b contact 36 for outputting a fully closed signal is connected to the terminal P1 of the shutter control panel 61 (the common terminal of the electric opening / closing operation unit 71).

連動制御器5は、ワンショット又は長時間継続的発報の防災信号BSを受けることによって、端子DC−D間の自動閉鎖装置31内のソレノイド(DC SOL)に直流24V信号を供給し、ブレーキ機構2を制動状態から解除状態にして、シャッターカーテン4を自重降下させる。ブレーキ機構2が制動状態から解除状態になると、これに連動してマイクロスイッチMS1によって連動制御器5の端子DC−DA間が接続され、ブレーキ機構2が解除されたことが連動制御器5に伝達される。これとほぼ同時に、マイクロスイッチMS2がオンして、復旧用電磁ソレノイド(AC SOL)が通電可能状態となる。   The interlock controller 5 supplies a 24V DC signal to the solenoid (DC SOL) in the automatic closing device 31 between the terminals DC-D by receiving a disaster signal BS of one-shot or long-time continuous alerting, and brakes The mechanism 2 is released from the braking state, and the shutter curtain 4 is lowered by its own weight. When the brake mechanism 2 is released from the braking state, the terminal DC-DA of the interlock controller 5 is connected by the micro switch MS1 in conjunction with this, and the release of the brake mechanism 2 is transmitted to the interlock controller 5. Is done. At substantially the same time, the micro switch MS2 is turned on, and the recovery electromagnetic solenoid (AC SOL) is ready to be energized.

復旧用電磁ソレノイド(AC SOL)が通電可能状態となった後に、電動開閉用操作部71の開ボタン7A又は閉ボタン7Cが押し操作された場合、自動閉鎖装置34は作動中にあるので、作動中信号を出力するa接点35は閉状態にあり、シャッターカーテン4は未だ全閉していない閉動作中なので全閉信号を出力するb接点36も閉状態にあるので、電動開閉用操作部71の停ボタン7Bが押し操作されたのと同じ状態となる。従って、電動開閉用操作部71の開ボタン7A又は閉ボタン7Cが操作されてもそれは無効なものとなり、自動閉鎖装置34はシャッターカーテン4の自重閉鎖を維持することとなる。また、電動開閉用操作部71の開ボタン7Aが押し操作されても、復旧用電磁ソレノイド(AC SOL)はシャッター制御盤61に端子P5に接続されているので、復旧用電磁ソレノイド(AC SOL)は動作することなく、自動閉鎖装置34の復旧操作も無効となる。一方、シャッターカーテン4が全閉すると、全閉信号を出力するa接点33が開状態になるので、電動開閉用操作部71の停ボタン7Bが非操作状態と同じになり、開ボタン7A又は閉ボタン7Cが有効となり、開ボタン7Aが押し操作されるとシャッターカーテン4は開動作するようになり、また、復旧用電磁ソレノイド(AC SOL)も動作し、自動閉鎖装置31の復旧操作が可能となる。   If the open button 7A or the close button 7C of the electric opening / closing operation unit 71 is pushed after the recovery electromagnetic solenoid (AC SOL) is ready to be energized, the automatic closing device 34 is in operation. Since the a contact 35 for outputting the intermediate signal is in the closed state and the shutter curtain 4 is in the closed operation which has not been fully closed yet, the b contact 36 for outputting the fully closed signal is also in the closed state. This is the same state as when the stop button 7B is pressed. Therefore, even if the open button 7A or the close button 7C of the electric opening / closing operation unit 71 is operated, it becomes invalid, and the automatic closing device 34 maintains the dead weight closing of the shutter curtain 4. Even if the open button 7A of the electric opening / closing operation unit 71 is pressed, the restoration electromagnetic solenoid (AC SOL) is connected to the terminal P5 of the shutter control panel 61, so that the restoration electromagnetic solenoid (AC SOL) Does not operate, and the recovery operation of the automatic closing device 34 becomes invalid. On the other hand, when the shutter curtain 4 is fully closed, the contact a 33 that outputs a fully closed signal is opened, so that the stop button 7B of the electric opening / closing operation unit 71 is the same as the non-operating state, and the open button 7A or closed When the button 7C is activated and the open button 7A is pressed, the shutter curtain 4 opens, and the recovery electromagnetic solenoid (AC SOL) also operates to allow the automatic closing device 31 to be restored. Become.

図5は、本発明に係る開閉体装置の結線図のさらに別の実施例を示す図である。図5において、図3と同じ構成のものには同一の符号が付してあるので、その説明は省略する。図5の実施例が図3のものと異なる点は、シャッター制御盤6の端子P2と電動開閉用操作部7の開ボタン7Aの端子との間に自動閉鎖装置31の作動中信号を出力するb接点32を直列に接続し、さらにこのb接点32に対してシャッターカーテン4の全閉信号を出力するa接点33を並列に接続している点である。すなわち、この実施例では、直接、電動開閉用操作部7の開ボタン7Aのみを無効にしたものである。   FIG. 5 is a view showing still another embodiment of the connection diagram of the opening / closing device according to the present invention. In FIG. 5, since the same code | symbol is attached | subjected to the thing of the same structure as FIG. 3, the description is abbreviate | omitted. The embodiment of FIG. 5 differs from that of FIG. 3 in that an operating signal of the automatic closing device 31 is output between the terminal P2 of the shutter control panel 6 and the terminal of the open button 7A of the electric opening / closing operation unit 7. The b contact 32 is connected in series, and the a contact 33 that outputs a fully closed signal of the shutter curtain 4 is connected to the b contact 32 in parallel. That is, in this embodiment, only the open button 7A of the electric opening / closing operation unit 7 is directly invalidated.

連動制御器5は、ワンショット又は長時間継続的発報の防災信号BSを受けることによって、端子DC−D間の自動閉鎖装置31内のソレノイド(DC SOL)に直流24V信号を供給し、ブレーキ機構2を制動状態から解除状態にして、シャッターカーテン4を自重降下させる。ブレーキ機構2が制動状態から解除状態になると、これに連動してマイクロスイッチMS1によって連動制御器5の端子DC−DA間が接続され、ブレーキ機構2が解除されたことが連動制御器5に伝達される。これとほぼ同時に、マイクロスイッチMS2がオンして、復旧用電磁ソレノイド(AC SOL)が通電可能状態となる。   The interlock controller 5 supplies a 24V DC signal to the solenoid (DC SOL) in the automatic closing device 31 between the terminals DC-D by receiving a disaster signal BS of one-shot or long-time continuous alerting, and brakes The mechanism 2 is released from the braking state, and the shutter curtain 4 is lowered by its own weight. When the brake mechanism 2 is released from the braking state, the terminal DC-DA of the interlock controller 5 is connected by the micro switch MS1 in conjunction with this, and the release of the brake mechanism 2 is transmitted to the interlock controller 5. Is done. At substantially the same time, the micro switch MS2 is turned on, and the recovery electromagnetic solenoid (AC SOL) is ready to be energized.

復旧用電磁ソレノイド(AC SOL)が通電可能状態となった後に、電動開閉用操作部7の開ボタン7Aが押し操作された場合、自動閉鎖装置31は作動中にあるので、作動中信号を出力するb接点32は開状態にあり、シャッターカーテン4は未だ全閉していない閉動作中なので全閉信号を出力するa接点33も開状態にある。従って、電動開閉用操作部7の開ボタン7Aが操作されてもそれは無効なものとなり、自動閉鎖装置31はシャッターカーテン4の自重閉鎖を維持することとなる。また、電動開閉用操作部7の開ボタン7Aが押し操作されても、復旧用電磁ソレノイド(AC SOL)は動作することなく、自動閉鎖装置31の復旧操作も無効となる。一方、シャッターカーテン4が全閉すると、全閉信号を出力するa接点33が閉状態になるので、電動開閉用操作部7の停ボタン7Bに電流が供給され、開ボタン7A又は閉ボタン7Cが有効となり、開ボタン7Aが押し操作されるとシャッターカーテン4は開動作するようになり、また、復旧用電磁ソレノイド(AC SOL)も動作し、自動閉鎖装置31の復旧操作が可能となる。   If the open button 7A of the electric opening / closing operation unit 7 is pushed after the recovery electromagnetic solenoid (AC SOL) becomes energized, the automatic closing device 31 is in operation and outputs an in-operation signal. The b contact 32 to be opened is in the open state, and since the shutter curtain 4 is not yet fully closed, the a contact 33 for outputting the fully closed signal is also in the open state. Accordingly, even if the open button 7A of the electric opening / closing operation unit 7 is operated, it becomes invalid, and the automatic closing device 31 maintains the self-weight closing of the shutter curtain 4. Further, even when the open button 7A of the electric opening / closing operation unit 7 is pressed, the restoration electromagnetic solenoid (AC SOL) does not operate, and the restoration operation of the automatic closing device 31 becomes invalid. On the other hand, when the shutter curtain 4 is fully closed, the contact a 33 that outputs a fully closed signal is closed, so that a current is supplied to the stop button 7B of the electric opening / closing operation unit 7, and the open button 7A or the close button 7C is When the opening button 7A is pushed and operated, the shutter curtain 4 opens, and the recovery electromagnetic solenoid (AC SOL) also operates, so that the automatic closing device 31 can be recovered.

However, all or part of them may be configured with switches that are not push buttons. Good. For example, it is possible to use an output contact that outputs an instruction command for opening, stopping, and closing in a remote control receiver in response to an operation of the remote control transmitter. For example, it can be used as an output contact point of a sensing signal of sensors for automatic control, or an output contact point of a control signal from another device linked to the shutter device or another device for automatically controlling the shutter device. is there.
