　かごドア装置９は、複数の投光器２６と複数の受光器２７とを備える。 The car door device 9 includes a plurality of light emitters 26 and a plurality of light receivers 27.
　複数の投光器２６は、一対のかごドア１３の一方の戸当たり側において鉛直方向に並んで設けられる。複数の投光器２６の各々は、一対のかごドア１３の他方に向けて水平方向に光を発し得るように設けられる。 The plurality of projectors 26 are provided in a vertical direction on one door stop side of the pair of car doors 13.

The control device 10 causes the door control device 23 to open the pair of car doors 13.
　次に、図３と図４とを用いて、一対のかごドア１３の吊り状態の判定方法を説明する。
　図３は実施の形態１におけるエレベーターの制御装置による一対のかごドアの吊り状態の判定方法を説明する。図４は実施の形態１におけるエレベーターの制御装置が適用されるエレベーターの複数の受光器の受光量を示す図である。 Next, a method of determining the suspended state of the pair of car doors 13 will be described with reference to FIGS.
FIG. 3 illustrates a method of determining a suspended state of a pair of car doors by the elevator control device according to the first embodiment. FIG. 4 is a diagram illustrating the amounts of light received by a plurality of light receivers of the elevator to which the elevator control device according to the first embodiment is applied.
　図３に示されるように、制御装置１０は、記憶部１０ａと判定部１０ｂとを備える。 制 御 As shown in FIG. 3, the control device 10 includes a storage unit 10a and a determination unit 10b.
　記憶部１０ａは、複数の投光器２６の各々が光を発しているときの複数の受光器２７の各々の受光量を示す情報を記憶する。判定部１０ｂは、記憶部１０ａにより記憶された情報に対応した受光量に基づいてドアの吊り状態を判定する。記憶部１０ａには、予め吊り状態が正常な状態において複数の投光器２６の各々が光を発しているときのかごドア１３の移動距離に対応した複数の受光器２７の受光量を示す情報が記憶されている。判定部１１ｂは、診断時に複数の受光器２７の少なくとも一つの受光量が所定値以上低下した場合、ドア吊り状態に異常が有ると判定する。 The storage unit 10a stores information indicating the amount of light received by each of the plurality of light receivers 27 when each of the plurality of light emitters 26 emits light. The determination unit 10b determines the suspended state of the door based on the amount of received light corresponding to the information stored by the storage unit 10a. The storage unit 10a previously stores information indicating the amount of light received by the plurality of light receivers 27 corresponding to the moving distance of the car door 13 when each of the plurality of light emitters 26 emits light in a normal suspended state. Have been. The determination unit 11b determines that there is an abnormality in the suspended state of the door when at least one of the light receiving amounts of the plurality of light receivers 27 decreases by a predetermined value or more at the time of diagnosis.
　例えば、図３においては、かごドア１３の一方の上部は、図３においては図示されない乗場３の側に倒れている。これに対し、かごドア１３の一方の下部は、図３においては図示されないかご６の内部の側に倒れている。 For example, in FIG. 3, one upper part of the car door 13 has fallen toward the landing 3 not shown in FIG. On the other hand, one lower part of the car door 13 has fallen toward the inside of the car 6 not shown in FIG.
　例えば、下から３番目の投光器２６と下から３番目の受光器２７とのずれ量は、ほとんどない。 For example, there is almost no deviation between the third light projector 26 from the bottom and the third light receiver 27 from the bottom.
　例えば、下から２番目の投光器２６と下から２番目の受光器２７とのずれ量は、下から３番目の投光器２６と下から３番目の受光器２７とのずれ量よりも大きい。例えば、最も下の投光器２６と最も下の受光器２７とのずれ量は、下から２番目の投光器２６と下から２番目の受光器２７とのずれ量よりも大きい。 For example, the amount of deviation between the second lowermost light projector 26 and the second lowermost light receiver 27 is larger than the amount of deviation between the third lowermost light emitter 26 and the third lowermost light receiver 27. For example, the amount of deviation between the lowermost light projector 26 and the lowermost light receiver 27 is larger than the amount of deviation between the second lower light projector 26 and the second lower light receiver 27.
　例えば、下から４番目の投光器２６と下から４番目の受光器２７とのずれ量は、下から３番目の投光器２６と下から３番目の受光器２７とのずれ量よりも大きい。例えば、下から５番目の投光器２６と下から５番目の受光器２７とのずれ量は、下から４番目の投光器２６と下から４番目の受光器２７とのずれ量よりも大きい。例えば、最も上の投光器２６と最も上の受光器２７とのずれ量は、下から５番目の投光器２６と下から５番目の受光器２７とのずれ量よりも大きい。 For example, the amount of deviation between the fourth light projector 26 from the bottom and the fourth light receiver 27 from the bottom is larger than the amount of deviation between the third light projector 26 from the bottom and the third light receiver 27 from the bottom. For example, the amount of deviation between the fifth light emitter 26 from the bottom and the fifth light receiver 27 from the bottom is larger than the amount of deviation between the fourth light emitter 26 from the bottom and the fourth light receiver 27 from the bottom. For example, the shift amount between the uppermost light emitter 26 and the uppermost light receiver 27 is larger than the shift amount between the fifth light emitter 26 from the bottom and the fifth light receiver 27 from the bottom.
　この場合、図４に示されるように、複数の受光器２７の各々の受光量は、複数の投光器２６の各々とのずれ量に応じてかごドア１３の移動距離とともに変化する。 In this case, as shown in FIG. 4, the amount of light received by each of the plurality of light receivers 27 changes with the moving distance of the car door 13 in accordance with the amount of deviation from each of the plurality of light emitters 26.
　例えば、下から３番目の受光器２７の受光量は、かごドア１３が移動してもほとんど変化しない。 For example, the amount of light received by the third light receiver 27 from the bottom hardly changes even if the car door 13 moves.
　例えば、下から２番目の受光器２７の受光量は、かごドア１３の移動に追従して下から３番目の受光器２７の受光量の変化よりも大きく変化する。例えば、最も下の受光器２７の受光量は、かごドア１３の移動に追従して下から２番目の受光器２７の受光量の変化よりも大きく変化する。 For example, the amount of light received by the second light receiver 27 from the bottom changes more greatly than the change in the amount of light received by the third light receiver 27 from the bottom following the movement of the car door 13. For example, the light reception amount of the lowermost light receiver 27 changes more greatly than the change of the light reception amount of the second lower light receiver 27 following the movement of the car door 13.
　例えば、下から４番目の受光器２７の受光量は、かごドア１３の移動に追従して下から３番目の受光器２７の受光量の変化よりも大きく変化する。例えば、下から５番目の受光器２７の受光量は、かごドア１３の移動に追従して下から４番目の受光器２７の受光量の変化よりも大きく変化する。例えば、最も上の受光器２７の受光量は、かごドア１３の移動に追従して下から５番目の受光器２７の受光量の変化よりも大きく変化する。 For example, the amount of light received by the fourth light receiver 27 from the bottom changes more greatly than the change in the amount of light received by the third light receiver 27 from the bottom following the movement of the car door 13. For example, the light reception amount of the fifth light receiver 27 from the bottom changes more greatly than the change of the light reception amount of the fourth light receiver 27 from the bottom following the movement of the car door 13. For example, the light reception amount of the uppermost light receiver 27 changes more greatly than the change of the light reception amount of the fifth lower light receiver 27 following the movement of the car door 13.
　図４においては図示されない制御装置１０は、この際の受光量の変化のばらつきに基づいて一対のかごドア１３の吊り状態において調整が必要となる箇所を判定する。 (4) The control device 10 not shown in FIG. 4 determines a portion that needs to be adjusted in the suspended state of the pair of car doors 13 based on the variation in the change in the amount of received light at this time.
　次に、図５を用いて、制御装置１０の動作の概要を説明する。
　図５は実施の形態１におけるエレベーターの制御装置の動作の概要を説明するためのフローチャートである。 Next, an outline of the operation of the control device 10 will be described with reference to FIG.
FIG. 5 is a flowchart for explaining the outline of the operation of the elevator control device according to the first embodiment.
　ステップＳ１では、制御装置１０は、一対のかごドア１３が閉じ始めたか否かを判定する。ステップＳ１で一対のかごドア１３が閉じ始めていない場合、制御装置１０は、ステップＳ１の動作を継続する。ステップＳ１で一対のかごドア１３が閉じ始めた場合、制御装置１０は、ステップＳ２の動作を行う。 In step S1, the control device 10 determines whether or not the pair of car doors 13 has begun to close. If the pair of car doors 13 has not started closing in step S1, the control device 10 continues the operation of step S1. When the pair of car doors 13 starts closing in step S1, the control device 10 performs the operation of step S2.
　ステップＳ２では、制御装置１０は、複数の受光器２７の各々の受光量の変化を示す情報を記憶する。その後、制御装置１０は、ステップＳ３の動作を行う。 In step S2, the control device 10 stores information indicating a change in the amount of received light of each of the plurality of light receivers 27. Thereafter, the control device 10 performs the operation of step S3.
　ステップＳ３では、制御装置１０は、複数の受光器２７の各々の受光量の変化のばらつきの状態に基づいて一対のかごドア１３の吊り状態が正常であるか否かを判定する。 In step S <b> 3, the control device 10 determines whether or not the hanging state of the pair of car doors 13 is normal based on the state of variation in the change in the amount of received light of each of the plurality of light receivers 27.
　ステップＳ３で一対のかごドア１３の吊り状態が正常である場合、制御装置１０は、ステップＳ１の動作を行う。ステップＳ３で一対のかごドア１３の吊り状態が正常でない場合、制御装置１０は、ステップＳ４の動作を行う。 If the hanging state of the pair of car doors 13 is normal in step S3, the control device 10 performs the operation of step S1. If the suspended state of the pair of car doors 13 is not normal in step S3, the control device 10 performs the operation of step S4.
　ステップＳ４では、制御装置１０は、複数の受光器２７の各々の受光量のばらつきの状態に基づいて一対のかごドア１３の吊り状態において調整が必要となる箇所を判定する。例えば、かごドア１３の上部付近にのみ受光量の変化のばらつきがあると判定される場合には、調整箇所として、ドアハンガー１４（取付状態の悪化、変形）、ハンガーローラ１５（変形、損傷）、ドアレール１６（変形、磨耗）等が候補にあげられる。例えば、かごドア１３の下部付近にのみ受光量の変化のばらつきがあると判定される場合には、調整箇所として、ドアシュー２４（取付状態の悪化、変形、磨耗）、敷居２５の溝部（磨耗、異物混入）が候補にあげられる。例えば、かごドア１３の中央部付近にのみ受光量の変化のばらつきがあると判定される場合には、調整箇所として、かごドア１３（変形、損傷）が候補にあげられる。その後、制御装置１０は、ステップＳ５の動作を行う。 In step S <b> 4, the control device 10 determines a position that needs to be adjusted in the suspended state of the pair of car doors 13 based on the variation in the amount of received light of each of the plurality of light receivers 27. For example, if it is determined that there is a variation in the change in the amount of received light only near the upper part of the car door 13, the door hanger 14 (deterioration or deformation of the mounting state) and the hanger roller 15 (deformation or damage) are to be adjusted. , Door rails 16 (deformation, wear), and the like. For example, if it is determined that there is a variation in the change in the amount of received light only near the lower part of the car door 13, the door shoe 24 (deterioration, deformation, and wear), the groove portion of the sill 25 (wear, Foreign matter) is a candidate. For example, when it is determined that there is a variation in the change in the amount of received light only near the center of the car door 13, the car door 13 (deformation, damage) is a candidate for the adjustment location. Thereafter, the control device 10 performs the operation of step S5.
　ステップＳ５では、制御装置１０は、調整が必要となる箇所を示す情報を情報センター装置１２等の外部に送信する。その後、制御装置１０は、ステップＳ１の動作を行う。 In step S5, the control device 10 transmits information indicating a location that needs to be adjusted to the outside of the information center device 12 or the like. Thereafter, the control device 10 performs the operation of step S1.
　以上で説明した実施の形態１によれば、制御装置１０は、複数の受光器２７の各々の受光量の変化に基づいて一対のかごドア１３の吊り状態を判定する。このため、一対のかごドア１３の吊り状態を容易に把握することができる。その結果、一対のかごドア１３の吊り状態を短時間で再調整することができる。 According to the first embodiment described above, the control device 10 determines the suspended state of the pair of car doors 13 based on the change in the amount of light received by each of the plurality of light receivers 27. Therefore, the suspended state of the pair of car doors 13 can be easily grasped. As a result, the suspended state of the pair of car doors 13 can be readjusted in a short time.
　なお、エレベーターの通常運転時の戸開閉、または、予め設定されたスケジュールで実施される診断運転時の戸開閉において一対のかごドア１３の吊り状態を判定すれば、一対のかごドア１３の開閉の不具合が発生する前に一対のかごドア１３の吊り状態を再調整することができる。 In addition, if the hanging state of the pair of car doors 13 is determined in the door opening and closing during normal operation of the elevator, or the door opening and closing during diagnostic operation performed according to a preset schedule, the opening and closing of the pair of car doors 13 is performed. The suspension state of the pair of car doors 13 can be readjusted before a trouble occurs.
　具体的には、制御装置１０は、複数の受光器２７の各々の受光量の変化のばらつきに基づいて一対のかごドア１３の吊り状態について調整が必要となる箇所を判定する。このため、一対のかごドア１３の吊り状態をより正確に把握することができる。 Specifically, the control device 10 determines a position where the suspension state of the pair of car doors 13 needs to be adjusted based on the variation in the change in the amount of received light of each of the plurality of light receivers 27. For this reason, the suspended state of the pair of car doors 13 can be grasped more accurately.
　また、制御装置１０は、調整が必要となる箇所を示す情報を外部に送信する。このため、一対のかごドア１３の吊り状態の調整を容易に行うことができる。 {Circle around (4)} The control device 10 transmits information indicating a portion requiring adjustment to the outside. Therefore, the suspension state of the pair of car doors 13 can be easily adjusted.
　なお、実施の形態１と同様の方法で片開き式のドアの吊り状態を判定してもよい。この場合も、当該ドアの吊り状態を容易に把握することができる。 The hanging state of the one-sided door may be determined in the same manner as in the first embodiment. Also in this case, the hanging state of the door can be easily grasped.
　また、実施の形態１と同様の方法で機械室２がないエレベーターのドアの吊り状態を判定してもよい。この場合も、当該ドアの吊り状態の吊り状態を容易に把握することができる。 In addition, the hanging state of the elevator door without the machine room 2 may be determined in the same manner as in the first embodiment. Also in this case, the suspended state of the door can be easily grasped.
　また、実施の形態１ではエレベーターの制御装置１０にてかごドア１３の吊り状態を診断する構成としたが、診断機能を監視装置１１に設けてもよい。この場合、エレベーターの制御装置１０は、通常運転時の戸開閉の際、又は、診断運転時の戸開閉の際に複数の受光器２７の各々の受光量を監視装置１１に送信すればよい。 In the first embodiment, the elevator control device 10 diagnoses the hanging state of the car door 13, but a diagnostic function may be provided in the monitoring device 11. In this case, the elevator control device 10 may transmit the received light amounts of the plurality of light receivers 27 to the monitoring device 11 when the door is opened and closed during normal operation or when the door is opened and closed during diagnostic operation.
