Abstract
Description
エレベータドアの制御装置は、通常、ドアモータ等のトルクを伝達機構を介してドアパネルへ伝えることによりかごドアを水平方向に自動開閉させるものである。
この位置スイッチに関しては、光の遮り(遮光)や反射を利用して全開位置及び全閉位置を検出する光スイッチ(投受光器)が、機械式等の他の方式のスイッチに比べて精度がよく、また、異物や水等にも比較的強いことから広く利用されている。
図1から図3は、この発明の実施の形態1に係るもので、図1はエレベータドア制御装置の全体構成を示す正面図、図2はエレベータドア制御装置のドアパル位置検出部における共通的な構成を模式的に説明する図、図3はエレベータドア制御装置のドアパル位置検出部の構成を模式的に説明する図である。
このかご出入口1には左右一対のかご戸を構成するかごドアパネル2が略水平方向開閉自在に設けられている。そして、これらのかごドアパネル2の上端部には、かごドアハンガー2aがそれぞれ取付られており、このかごドアハンガー2aの上部にはかごドアローラ2bが回転可能に軸着されている。
また、桁3の左右方向の他側には従動車8が回動自在に取付けられており、これら駆動車7及び従動車8には無端状の歯付きベルト9が巻き掛けられている。この歯付きベルト9の内側には等間隔で凹凸が付けられて歯が形成されており、駆動車7及び従動車8にはこの歯に係合する凹凸が付けられている。
こうして歯付きベルト9の歯が駆動車7及び従動車8の凹凸に歯合して、ドアモータ6の回転駆動が歯付きベルト9の循環移動へと伝達される巻掛伝動機構であるドア駆動装置5が構成されている。
また、桁3にはドアパネル2が全開状態及び全閉状態を超えて移動することを規制するストッパ11が設けられている。このストッパ11は、ドアパネル2が全開状態及び全閉状態にあるときにドアハンガー2aの端部が当接する位置に配設されている。
第1の遮蔽板12は、ドアパネル2が全開位置にあるときにこの第1の遮蔽板12が位置スイッチ14のコ字型の内側に位置するように配置されている。また、第2の遮蔽板13は、ドアパネル2が全閉位置にあるときにこの第2の遮蔽板13が位置スイッチ14のコ字型の内側に位置するように配置されている。
エレベータドアすなわち左右一対のドアパネル2の開閉動作はドア制御装置本体18により制御されている。
ドアモータ6の回転軸には、この回転軸の回転角度を検出し回転角情報信号として出力する図示しないパルスエンコーダが設けられており、ドア制御装置本体18は、パルスエンコーダからの回転角情報信号や位置スイッチ14から出力される全開位置及び全閉位置の検出信号に基づいてドアパネル2の位置を把握し、ドアモータ6の回転を制御してドアパネル2を水平方向に開閉させる。
すなわち、前述のごとく、位置スイッチ14は側面視略コ字型を呈し、桁3に取付けられている。そして、コ字型の一方の突出部には例えば発光ダイオード(LED)等からなる投光器15が設けられており、コ字型の他方の突出部には例えばフォトダイオード等からなる受光器16が設けられている。これらの投光器15及び受光器16は互いに対向するように配置されており、通常時においては、投光器15から投光された光17は受光器16により受光される。
この接合部19には、左右方向に長径を有する長孔19aが穿設されており、この長孔19aを通したボルト19bにより第1の遮蔽板12及び第2の遮蔽板13はドアハンガー2aへと螺着されている。
そして、この長孔19a内におけるボルト19bの螺着位置を変えることにより、第1の遮蔽板12及び第2の遮蔽板13の左右方向の取付位置が調整される。
従って、ドアパネル2が全開位置にあるときには第1の遮蔽板12により投光器15から投光される光17が遮光されて受光器16はこの光17を受光しなくなり、ドアパネル2が全閉位置にあることを検出することができる。
同様に、ドアパネル2が全閉位置にあるときには第2の遮蔽板13により投光器15から投光される光17が遮光されて受光器16はこの光17を受光しなくなり、ドアパネル2が全閉位置にあることを検出することができる。
以上が以後において説明するこの発明の各実施形態において共通する構成である。
すなわち、位置スイッチ14は、上下方向(すなわちドア開閉方向に直交しかつドアパネルと同一平面内にある方向、以下同じ)に並べて配置された第1の投光器15a及び第2の投光器15bを有している。そして、第1の投光器15aに対向する位置には第1の受光器16aが、第2の投光器15bに対向する位置には第2の受光器16bが、同じく上下方向に並べて配置されて設けられている。
第1の投光器15aから投光された第1の光17aは第1の受光器16aで受光され、この受光の有無によりドアパネル2の位置の検出が行われる。また、ドアパネル2の位置の検出は、第2の投光器15bから投光された第2の光17bの、第2の受光器16bによる受光の有無によっても行われる。
そして、第1の遮蔽板12は、第1の投光器15aから投光される第1の光17a及び第2の投光器15bから投光される第2の光17bの双方を同時に遮光できる上下方向寸法となるように調整される。これに対し、第2の遮蔽板13は、下方に配置される第2の投光器15bから投光される第2の光17bのみを遮光し、上方に配置される第1の投光器15aから投光される第1の光17aは遮光しない上下方向寸法に調整される。
なおここで、ドアパネルが全開位置又は全閉位置にある場合に、第1の遮蔽板が遮光する1以上の所定の光とは、第1の光及び第2の光のうち1以上の組合せを意味している。そして、第2の遮蔽板が遮光する、第1の遮蔽板が遮光する前記所定の光とは異なる1以上の所定の光とは、その光の組合せが異なれば第1の遮蔽板が遮光する所定の光と共通するものがあってもよい。
このため、前述同様の効果を奏することができる。
図1及び図4はこの発明の実施の形態2に係るもので、図1はエレベータドア制御装置の全体構成を示す正面図、図4はエレベータドア制御装置のドアパル位置検出部の構成を模式的に説明する図である。
前述した実施の形態1は、2つの遮蔽板の上下方向の寸法を互いに異ならせることにより、遮蔽する投光器からの光の数を異ならせることで、ドア全開状態及び全閉状態における位置スイッチからの出力信号を変化させてこれらの状態を区別可能なものとしたが、ここで説明する実施の形態2は、2つの遮蔽板の上下方向の取付位置を互いに異ならせることにより、遮蔽する投光器の光を変え、ドア全開状態及び全閉状態における位置スイッチからの出力信号を変化させてこれらの状態を区別するようにしたものである。
ここで、第1の遮蔽板の腕部12a及び第2の遮蔽板の腕部13aは、その上下方向の寸法が互いに異なっており、ここでは、第1の遮蔽板の腕部12aの上下方向寸法の方が、第2の遮蔽板の腕部13aの上下方向寸法よりも長くなっている。そして、第1の遮蔽板の腕部12aの上端には第1の遮蔽板12が、第2の遮蔽板の腕部13aの上端には第2の遮蔽板13が、それぞれ取付けられている。
なお、他の構成は実施の形態1と同様であって、その詳細説明は省略する。
図1及び図5はこの発明の実施の形態3に係るもので、図1はエレベータドア制御装置の全体構成を示す正面図、図5はエレベータドア制御装置のドアパル位置検出部の構成を模式的に説明する図である。
ここで説明する実施の形態3は、2つの投受光器を左右方向に並べて配置し、2つの遮蔽板により遮蔽する投光器の光を異ならせることで、ドア全開状態及び全閉状態における位置スイッチからの出力信号を変化させてこれらの状態を区別するようにしたものである。
第1の遮蔽板12及び第2の遮蔽板13をそれぞれ支持する第1の遮蔽板の腕部12a及び第2の遮蔽板の腕部13aの上下方向寸法は略同一である。
なお、他の構成は実施の形態1と同様であって、その詳細説明は省略する。
また、2つの遮蔽板のうち、いずれか一方の左右方向の寸法を長くして、2組両方の投受光器の光を遮光するようにしてもよい。
図1並びに図6及び図7はこの発明の実施の形態4に係るもので、図1はエレベータドア制御装置の全体構成を示す正面図、図6はエレベータドア制御装置のドアパル位置検出部の構成を模式的に説明する図、図7はエレベータドア制御装置の動作を示すフロー図である。
ここで説明する実施の形態4は、実施の形態3の構成において、一方の遮蔽板の左右方向寸法を2組の投受光器の左右方向の間隔寸法より長くするとともに、この長寸法の遮光板による2組の投受光器の遮光順序を加味することにより、ドアパネルが全開位置又は全閉位置のいずれかにあるかを判断するようにしたものである。
なお、他の構成は実施の形態3と同様であって、その詳細説明は省略する。
そして、ドアパネル2が全閉位置となったか否かの判別動作は、図7のフローに従って行われる。
すなわち、ドア制御装置本体18は、位置スイッチ14から出力される信号に基づいて、第1の受光器16a及び第2の受光器16bの両方が受光していない状態であるか否かについて確認を行う。この確認において、第1の受光器16a及び第2の受光器16bの両方が受光していない状態であることが確認された場合には、ステップS2へと移行する。
この確認において、遮光順番について第2の受光器16bが先であって第1の受光器16aが後であることが確認された場合はステップS3へと移行して、ドア制御装置本体18はドアパネル2が全閉状態にあると判断した後、ステップS1へと戻る。
このため、実施の形態3と同様の効果を奏することができるのに加えて、電源異常や位置スイッチ等のケーブル断線等といった、発生することにより第1の受光器及び第2の受光器の両方が受光していない状態となってしまう異常が発生したことを検知することが可能である。
ここで説明する実施の形態5は、実施の形態1から実施の形態4の構成において、受光器を、位置スイッチのコ字型の2つの突出部のうち、ドア駆動装置とは離間する側すなわち桁とは離間する側に設けるようにしたものである。

なお、他の構成や動作については、実施の形態1から実施の形態4のいずれかと同一であるため、その詳細説明は省略する。

ここで説明する実施の形態7は、実施の形態1から実施の形態6の構成において、位置スイッチの桁から離間する側の外側表面部に、この位置スイッチに設けられた受光器の受光状態を表示する受光表示器を設けるようにしたものである。
図9において説明しているのは、第1の受光器16a及び第2の受光器16bを上下方向に並べて配置した場合の例であり、従って、受光表示器20は、第1の受光器16aの受光状態を表示する第1の受光表示器20a及び第2の受光器16bの受光状態を表示する第2の受光表示器20bの2つが設けられている。
また、他の構成や動作については、実施の形態1から実施の形態6のいずれかと同一であるため、その詳細説明は省略する。

ここで説明する実施の形態8は、実施の形態1から実施の形態7の構成において、位置スイッチの左右方向両側に、外乱光が受光器に入射することを防止する外光遮蔽部を、遮蔽板の移動の妨げとならないようにして設けたものである。
また、この実施の形態の他の例として、図11に示すごとく、位置スイッチの左右方向寸法14aを他の実施の形態とものより長くすることにより、外光遮蔽部21を形成する。
なお、他の構成や動作については、実施の形態1から実施の形態7のいずれかと同一であるため、その詳細説明は省略する。
ここで説明する実施の形態9は、実施の形態1から実施の形態8の構成において、遮蔽板の表面を黒色の又は光の反射率が低い塗料や部材で覆うようにしたものである。
すなわち、第1の遮蔽板12及び第2の遮蔽板13の表面は、黒色の又は光の反射率が低い塗料や部材で覆われており、他の構成や動作については、実施の形態1から実施の形態8のいずれかと同一である。
図12は、この発明の実施の形態10に係るもので、エレベータドア制御装置のドアパル位置検出部の構成を模式的に説明する図である。
ここで説明する実施の形態10は、実施の形態1から実施の形態9の構成において、接合部の形状を側面視略L字型として、この接合部により下方から入射する外乱光を遮断するようにしたものである。
そして、この第1の遮蔽板12及び第2の遮蔽板13の取付位置に合わせて、位置スイッチ14の取付位置も調整されている。
