しかしながら、特許文献１に記載されたエレベーター装置では、引き込み検知時に引き込まれた状態でドアが停止するため、挟まれた状態から抜く事が困難となる。また、ドアマシンの電源を切る例も記載されているが、通常ドアには戸閉方向に力がかかるよう、ばねや錘で構成される自閉装置が備え付けられており、ドアクローザ―の戸閉力により、ドアは反転動作し戸閉することとなり、ドアが反転しても即時には引き込まれた手を離すことが出来ず、危険回避が難しいケースがあった。   However, in the elevator apparatus described in Patent Document 1, since the door stops in the state of being pulled in at the time of pull-in detection, it is difficult to pull out the pinched state. Although an example of turning off the power to the door machine is also described, a normal door is equipped with a self-closing device consisting of a spring and weight so that force is applied in the door closing direction, and the door closer of the door closer is closed. Due to the force, the door flips and closes, and even if the door is flipped, it is difficult to avoid danger because it is impossible to release the hand that was pulled in immediately.

上記課題を解決するために、本発明は、乗客の乗るかごと、かごに備えられるごドアと、かごドアに備えられる係合装置と、乗り場に設けられかごドアと係合装置を介して係合することで移動される乗り場ドアと、乗り場ドアを閉方向に自閉力を付勢する自閉装置と、かごドアを駆動するドア開閉駆動装置と、かごドア開動作時の異常を検出するドア開安全装置とを備え、ドア開安全装置が異常検出した場合、ドア開閉駆動装置はドア開方向の駆動力を発生させることを特徴とするエレベーターの提供。   In order to solve the above-described problems, the present invention relates to a passenger car, a car door provided in the car, an engagement device provided in the car door, and a car door provided in the landing via the car door and the engagement device. The landing door that is moved by combining, a self-closing device that urges the self-closing force in the closing direction of the landing door, a door opening and closing drive device that drives the car door, and an abnormality at the time of the car door opening operation are detected An elevator comprising: a door opening safety device, wherein the door opening / closing driving device generates a driving force in a door opening direction when the door opening safety device detects an abnormality.

本発明のエレベーターによれば、容易に引き込みを解消することができる。   According to the elevator of the present invention, the pull-in can be easily eliminated.

以下、本発明の実施例を図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１は、本発明の一実施例によるかごドアの正面図である。かごドアの開閉を制御するドア制御装置１と、かごドアを開方向または閉方向に駆動するドア開閉駆動装置２と、かごドア１１を乗り場ドア１４を係合する係合装置１２と、かごドア開動作時に挟み込み異常などを検出したときかごドア開動作を中止するドア開安全装置６Ａと、ドア閉動作時に挟み込みなどの異常を検出したときかごドア閉動作を中止するドア閉安全装置６Ｂとを備える。ドア開閉駆動装置２は、かごドアの開閉に伴う位置を検出するかごドア位置検出装置、及びかごドアにかかる力を検出するかご負荷検出装置を兼ねるが別部材によりこれを実現しても良い。   FIG. 1 is a front view of a car door according to an embodiment of the present invention. A door control device 1 that controls the opening and closing of the car door, a door opening and closing drive device 2 that drives the car door in an opening direction or a closing direction, an engagement device 12 that engages the car door 11 with the landing door 14, and a car door A door opening safety device 6A that stops the car door opening operation when a pinching abnormality is detected during the opening operation, and a door closing safety device 6B that stops the car door closing operation when an abnormality such as pinching is detected during the door closing operation. Prepare. The door opening / closing drive device 2 serves as a car door position detection device that detects a position associated with the opening and closing of the car door, and a car load detection device that detects a force applied to the car door, but this may be realized by a separate member.

図２は、本発明の一実施例による乗り場ドアの正面図である。乗り場ドア１４と、乗り場ドアを自閉方向に付勢させる自閉装置１３を備えている。自閉装置１３には、ばねや重力により閉じ方向へ付勢されるウェイトを利用するものが挙げられる。本実施例では、ウェイトの場合を中心に記述し、ばねの場合の制御については後述する。乗り場ドア１４は契合装置１２によりかごドア１１と契合されることで駆動するため、かごドア１１には自閉装置１３の自閉力がかかる。   FIG. 2 is a front view of a landing door according to an embodiment of the present invention. A landing door 14 and a self-closing device 13 for biasing the landing door in the self-closing direction are provided. Examples of the self-closing device 13 include a device that uses a weight biased in a closing direction by a spring or gravity. In this embodiment, the case of weight will be mainly described, and control in the case of spring will be described later. Since the landing door 14 is driven by being engaged with the car door 11 by the engagement device 12, the self-closing force of the self-closing device 13 is applied to the car door 11.

図３は、本発明の一実施例によるドア制御部のブロック構成図である。ドア制御装置は、自閉装置１３の自閉力と釣り合う力のみを掛けてかごドアを無負荷で保持状態とする自閉力バランス保持部３と、かごドアの開速度または閉速度を「超低速」と「通常速度」とに切り替えて制御し、ドア開閉駆動装置を動作させるドア開閉速度制御部４と、ドア開安全装置６Ａ及びドア閉安全装置６Ｂが動作したことを検出するドア安全装置動作検出部７と、ドア開安全装置６Ａ及びドア閉安全装置６Ｂが予め設定した設定値を超えて連続で動作を繰り返したかどうか判定する動作回数判定部８を有している。ドア制御装置１は制御盤に格納されるエレベーター制御装置１０との通信に従って動作する。なお、本実施例ではエレベーター制御装置１０は、制御盤に格納されるとしたが、ドア制御装置１にその機能を持たせても良い。   FIG. 3 is a block diagram of a door control unit according to an embodiment of the present invention. The door control device applies a force that balances with the self-closing force of the self-closing device 13 to hold the car door in a no-load state, and sets the opening speed or closing speed of the car door to "super" The door opening / closing speed control unit 4 that controls the operation by switching between “low speed” and “normal speed” and operates the door opening / closing drive device, and the door safety device that detects that the door opening safety device 6A and the door closing safety device 6B are operated. The operation detection unit 7 and the operation number determination unit 8 that determines whether the door opening safety device 6A and the door closing safety device 6B have continuously repeated operations exceeding preset values are provided. The door control device 1 operates according to communication with the elevator control device 10 stored in the control panel. In the present embodiment, the elevator control device 10 is stored in the control panel, but the door control device 1 may have the function.

図４は、ドア制御装置におけるドア開き処理動作を示すフローチャートである。スタートでエレベーター制御部１０はドア制御装置１に対しドア開き指令を出力し、ドア制御装置１はドア開閉速度制御部４を介して、通常速度でドアを開く力を出力するようドア開閉駆動装置２に信号を出力する。   FIG. 4 is a flowchart showing a door opening process operation in the door control device. At the start, the elevator control unit 10 outputs a door opening command to the door control device 1, and the door control device 1 outputs a force for opening the door at a normal speed via the door opening / closing speed control unit 4. 2 outputs a signal.

ステップＳ１でドア安全装置動作検出部７は、かごドアを開操作したときにドア開安全装置６Ａが動作したかを監視している。その結果、ドア安全装置動作検出部７が、ドア開安全装置６Ａの動作を検出した場合、ステップＳ２で動作回数判定部８は、ドア開閉動作時のドア安全装置動作回数が予め設定した所定回数を超えたかどうかを判定する。その結果、設定回数を超えていない場合、ステップＳ３で、エレベーター制御部１０における引き込み解消のための第一段階処理として、ドア速度開閉速度制御部４により、ドア閉速度を「通常速度」から「超低速」に切り替える。その後、ステップＳ４でドア速度開閉速度制御部４ドア閉信号をドア開閉駆動装置２に送信し、ドア開閉駆動装置２はかごドアを超低速で閉方向に駆動させる。ステップＳ５で、ドア安全装置動作検出部７はかごドアを閉方向に動作させた後にドア閉安全装置６Ｂが動作したかどうかを監視する。その結果、ドア安全装置動作検出部７による検出があった場合、ステップＳ７１に進んで詳細を後述するエレベーター制御部１０で引き込み解消のための第二段階処理を実施する。ドア安全装置動作検出部７によるドア閉安全装置６Ｂの検出がなかった場合、ステップＳ６で、かごドアを閉方向に動作させた後にドア安全装置動作検出部７によるドア開安全装置６Ａの動作の有無を確認する。これはドアの反転動作後も引き込まれ状態が継続しているかを確認するものであり、かごドア反転後に一定時間経過、または一定距離駆動後もドア開安全装置６Ａが動作しているかどうかをドア安全装置動作検出部７により検出する。ここで動作していない場合にはドア開安全装置６Ａが動作している場合は、反転動作により問題が解決した事が見込めるため、復帰動作であるステップＳ９に移行する。   In step S1, the door safety device operation detection unit 7 monitors whether the door opening safety device 6A has been operated when the car door is opened. As a result, when the door safety device operation detection unit 7 detects the operation of the door opening safety device 6A, in step S2, the operation frequency determination unit 8 determines that the door safety device operation frequency during the door opening / closing operation is a predetermined number of times set in advance. Judge whether or not. As a result, when the set number of times is not exceeded, in step S3, the door speed opening / closing speed control unit 4 changes the door closing speed from “normal speed” to “ Switch to "Super slow". Thereafter, in step S4, the door speed opening / closing speed control unit 4 sends a door closing signal to the door opening / closing driving device 2, and the door opening / closing driving device 2 drives the car door in the closing direction at an extremely low speed. In step S5, the door safety device operation detection unit 7 monitors whether the door closing safety device 6B has been operated after the car door is operated in the closing direction. As a result, when there is a detection by the door safety device operation detection unit 7, the process proceeds to step S71, and the elevator control unit 10, which will be described in detail later, carries out a second stage process for retraction cancellation. If the door safety device operation detection unit 7 does not detect the door closing safety device 6B, in step S6, the door safety device operation detection unit 7 operates the door opening safety device 6A after the car door is moved in the closing direction. Check for presence. This is to confirm whether or not the state where the car is pulled in even after the reversing operation of the door is continued, and whether the door opening safety device 6A is operating after a certain time has elapsed after the car door reversing or after a certain distance driving. It is detected by the safety device operation detection unit 7. If the door opening safety device 6A is operating when it is not operating here, it can be expected that the problem has been solved by the reversing operation, and the process proceeds to step S9, which is a return operation.

ステップＳ７１は、反転動作後に、ドア開安全装置６Ａ又はドア閉安全装置６Ｂの動作をドア安全装置動作検出部７が検出している場合に行われる処理である。この様な場合、幼い子供やお年寄りなどの引き込みが発生していた場合、大人の場合とは異なり反応速度が遅かったり戸惑ったりした結果、引き込みや、それに伴うドアの退入室にともなうトラブルが解消していない可能性がある。そこで、引き込み解消のための第二段階処理として、ステップＳ７１では、ドア速度開閉速度制御部４はかごドアを停止させる力を出力するようドア開閉駆動装置２にドア停止信号を出力する。このとき戸閉方向にかごドア及び乗り場ドアは稼動しているため、運動エネルギーを持ちこのエネルギーは自閉方向の力となる。また、自閉装置１３により、自閉方向の力が生じている。つまり、戸閉方向に稼動中のドアを停止させるために、自閉装置１３に伴う自閉力よりも大きな戸開方向の力をドア開閉駆動装置２に出力させることになる。その他、乗客等によりドアに力が加えられかごドアに速度が生じようとした場合、逆方向に力をかける事で、かごドア速度が０に近づくように制御をする。   Step S71 is a process performed when the door safety device operation detector 7 detects the operation of the door opening safety device 6A or the door closing safety device 6B after the reversing operation. In such a case, if a young child or an elderly person is drawn in, the reaction speed is slow or confused, unlike an adult, so the trouble associated with the drawing-in and the door entry / exit room is eliminated. It may not have been done. Therefore, as a second stage process for retraction cancellation, in step S71, the door speed opening / closing speed control unit 4 outputs a door stop signal to the door opening / closing drive device 2 so as to output a force for stopping the car door. At this time, since the car door and the landing door are operating in the door closing direction, they have kinetic energy and this energy becomes a force in the self-closing direction. The self-closing device 13 generates a force in the self-closing direction. That is, in order to stop the door that is operating in the door closing direction, a force in the door opening direction larger than the self-closing force associated with the self-closing device 13 is output to the door opening / closing drive device 2. In addition, when a force is applied to the door by a passenger or the like and a speed is about to be generated in the car door, the car door speed is controlled to approach 0 by applying a force in the reverse direction.

かごドア停止後、ステップＳ７として、自閉力バランス保持部３は、ドア開閉駆動装置２に対し、自閉力と釣り合う力を出力させるバランス信号を送信する。この状態では、乗客等により力が加えられかごドア速度が０でなくなっても、かごドア速度を０に近づける様な制御はしない。これにより、かごドアは無負荷状態となり、停止状態から新たな力を加えない限りは停止しているものの、軽い力でかごドア及び乗り場ドアを動かす事が出来るようになり、誰でも容易に引き込みを解消することができるようになる。ステップＳ７で出力する力は自閉装置による自閉力と反対方向の同じ大きさの力である必要はなく、自閉力と反対方向の力であってかごドア及び乗り場のドアの移動させる際の負荷を低減させる力であればよい。   After the car door stops, the self-closing force balance holding unit 3 transmits a balance signal for outputting a force balanced with the self-closing force to the door opening / closing drive device 2 as step S7. In this state, even if a force is applied by a passenger or the like and the car door speed is not zero, the car door speed is not controlled to approach zero. As a result, the car door is in a no-load state and is stopped unless a new force is applied from the stopped state, but the car door and the landing door can be moved with a light force, and anyone can easily pull it in. Can be eliminated. The force output in step S7 does not have to be the same magnitude in the direction opposite to the direction of the self-closing force by the self-closing device, and is a force in the direction opposite to the self-closing force and is used to move the car door and the landing door. Any force may be used as long as the load is reduced.

なお本実施例では、自閉装置としてウェイトを用いているが、ばねを用いた場合、かごドアの位置に応じてばね力により生じる自閉力が変化する。このばね力は、かごドアの位置によってどの程度の閉じ力として作用するか算出することができるので、かごドアの位置に応じてばね力と同等の力を掛けて、開状態を保持することができる。このＳ７１及びＳ７の引き込み解消の第二段階処理によって、かごドアは停止状態となり、しかも、必要に応じてかごドアの重みを感じることなく手動で移動することができる状態となる。こうして、非力であるお年寄りや幼い子供のように素早い対処ができなかったり、引き込まれた状況を判断することに時間を要したりする場合であっても、この処理中に簡単にかごドアを手動で移動して、引き込み状態を解消させることができる。また、ステップＳ７で出力する力は自閉力と反対方向の全く同じ力である必要はなく、自閉力と反対方向の力であってかごドア及び乗り場のドアの移動させる際の負荷を低減させる力であればよい。また、かごドアや乗り場ドアの摩擦力を考慮してもよい。   In this embodiment, a weight is used as the self-closing device. However, when a spring is used, the self-closing force generated by the spring force changes according to the position of the car door. Since this spring force can be calculated as how much closing force acts depending on the position of the car door, a force equivalent to the spring force can be applied depending on the position of the car door to maintain the open state. it can. The car door is stopped by the second-stage process of canceling the pull-in in S71 and S7, and can be moved manually without feeling the weight of the car door as necessary. This way, even if you are unable to deal with it quickly, such as a powerless elderly person or a young child, or if it takes time to determine the situation you are pulled in, you can easily open the car door during this process. It can be moved manually to cancel the retracted state. Further, the force output in step S7 does not have to be exactly the same force in the direction opposite to the self-closing force, and is a force in the opposite direction to the self-closing force and reduces the load when moving the car door and the landing door. It only has to be a force to make. Moreover, you may consider the frictional force of a car door or a landing door.

その後、ステップＳ８で自閉力バランス保持部３は、自閉力と釣り合う力による保持時限を満了したかを判定する。予め設定した保持時限を満了した場合、自閉力バランス保持部３はステップＳ９でドア開閉力を定常状態に復帰させる。これは保持期限を満了した場合、引き込み状態は解決していると考えられるためである。   Thereafter, in step S8, the self-closing force balance holding unit 3 determines whether or not the holding time period due to the force balanced with the self-closing force has expired. When the preset holding time has expired, the self-closing force balance holding unit 3 returns the door opening / closing force to the steady state in step S9. This is because it is considered that the pull-in state has been solved when the retention period has expired.

その後、第二段階処理を終えるとかごドアの開動作を優先させて、ドア開閉駆動装置２は、ステップＳ１０でドア開動作を再度開始し、ステップＳ１１で今回のドア開動作が完了したかどうかを判定する。かごドア開動作完了が検出された場合、ドア速度制御部４は、ステップＳ１２でかごドア速度を「超低速」から「通常速度」に戻し、今回の処理が完了となる。   After that, when the second stage process is finished, priority is given to the car door opening operation, and the door opening / closing drive device 2 starts the door opening operation again in step S10, and whether or not the current door opening operation is completed in step S11. Determine. When the completion of the car door opening operation is detected, the door speed control unit 4 returns the car door speed from “ultra low speed” to “normal speed” in step S12, and the current process is completed.

一方、上述した第一段階処理や第二段階処理を行ったものの引き込み状態が解消されず、動作回数判定部８によるステップＳ２の判定で、ドア安全装置動作回数が予め設定した所定の規定回数を超えることも考えられる。この様なケースはドア開安全装置６Ａやドア閉防止用安全装置６Ｂの誤検出や、ドア開閉駆動装置２の故障などが考えられる。ドア開閉駆動装置２の故障が疑われる状況でＳ３からＳ８のような引き込み解消処理が適切に行えず、引き込みが解消しない可能性がある。そこで、動作回数判定部８で所定回数以上のドア安全装置動作を確認した場合、ステップＳ１３で、ドア制御開閉速度制御部に信号を与えて、ドア開閉駆動装置２を停止させ、かごドアの制御を行わない様にする。この結果ドア開閉駆動装置２は駆動しないので、かごドアには係合される乗り場ドアの備える自閉装置１３による自閉力がかかる状態となる。その後、ドア開閉駆動部２は、ステップＳ１４でかごドア開動作が完了したか、またはステップＳ１５でかごドア閉動作が完了したかを判定し、ドア閉じまたはドア開きいずれかが完了するまで待つ。ここで、ドア閉じ又はドア開きが生じるのは、自閉装置１３による自閉力によりドアが閉じるか、乗客によりドアが開かれる事によって生じる。   On the other hand, the pulled-in state of the first-stage process and the second-stage process described above is not resolved, and the door safety device operation frequency is set to a predetermined specified number of times set in advance in the determination of step S2 by the operation frequency determination unit 8. It is also possible to exceed. In such a case, a false detection of the door opening safety device 6A or the door closing prevention safety device 6B, a failure of the door opening / closing drive device 2, or the like can be considered. In a situation where a failure of the door opening / closing drive device 2 is suspected, there is a possibility that the pull-in cancellation process as in S3 to S8 cannot be performed properly and the pull-in is not canceled. Therefore, when the operation number determination unit 8 confirms the operation of the door safety device more than a predetermined number of times, a signal is given to the door control opening / closing speed control unit in step S13 to stop the door opening / closing drive device 2 and control the car door. Do not perform. As a result, since the door opening / closing drive device 2 is not driven, a self-closing force is applied to the car door by the self-closing device 13 provided in the landing door to be engaged. Thereafter, the door opening / closing drive unit 2 determines whether the car door opening operation is completed in step S14 or the car door closing operation is completed in step S15, and waits until either the door closing or the door opening is completed. Here, the door closing or door opening occurs when the door is closed by the self-closing force of the self-closing device 13 or when the door is opened by the passenger.

ステップＳ１４でかごドア開動作完了が検出された場合、自閉力バランス保持部３は、ステップＳ１７で戸開閉力を元の定常状態に復帰させる。一方、かごドア閉動作完了が検出された場合、ドア速度制御部４は、ステップＳ１６でかごドア開閉速度を「通常速度」から「超低速」に切り替え、上述したステップＳ９からステップＳ１２を実施する。   When the completion of the car door opening operation is detected in step S14, the self-closing force balance holding unit 3 returns the door opening / closing force to the original steady state in step S17. On the other hand, when the completion of the car door closing operation is detected, the door speed control unit 4 switches the car door opening / closing speed from “normal speed” to “ultra-low speed” in step S16, and executes steps S9 to S12 described above. .

本発明の実施に際して手順を変更したり、他の手順を追加したりすることができる。例えば本実施例では、ステップＳ１でドア開安全装置が動作した後、Ｓ２からＳ７１までの処理を行っているが、必ずしも行わなくてよく、ドア開安全装置が動作し引き込まれが検出された時点で、ステップＳ７で自閉力と釣り合う力のみを出力するようにしてもよい。   In carrying out the present invention, the procedure can be changed and other procedures can be added. For example, in this embodiment, after the door opening safety device is operated in step S1, the processing from S2 to S71 is performed. However, it is not always necessary, and the door opening safety device is operated and the pull-in is detected. In step S7, only the force that balances the self-closing force may be output.

かごドアの開動作中にドア安全装置５が異常を検出したとき、かごドア閉動作を通常時よりも低速とするドア開閉速度切替部４を設け、自閉力バランス保持部３は、ドア開閉速度切替部４による切り替え後に、ドア安全装置５による異常の検出がないときにかごドアを反転して一定距離閉動作させてから、かごドアの自閉力と釣り合う力によってかごドアを保持させるようにしている。このような構成によれば、かごドアを反転して一定距離閉動作させるときドア開閉速度切替部４によって超低速で行うことができるので、引き込み状態が継続していてもその乗客に悪影響を与えることはない。引き込み状態が継続しているときは余りドアを移動させることなくかごドアの自閉力と釣り合う力によってドアを保持させるので、引き込まれている状態の乗客に悪影響を与えることはない。   When the door safety device 5 detects an abnormality during the opening operation of the car door, a door opening / closing speed switching unit 4 is provided to make the car door closing operation slower than normal, and the self-closing force balance holding unit 3 opens and closes the door. After the switching by the speed switching unit 4, when no abnormality is detected by the door safety device 5, the car door is reversed and closed for a certain distance, and then the car door is held by a force balanced with the self-closing force of the car door. I have to. According to such a configuration, when the car door is reversed and closed for a certain distance, the door opening / closing speed switching unit 4 can perform the operation at an extremely low speed, so that even if the retracted state continues, the passenger is adversely affected. There is nothing. When the retracted state continues, the door is held by a force that balances the self-closing force of the car door without moving the door so much, so that the passenger in the retracted state is not adversely affected.

かごドア近傍にいる乗客がドア開閉動作時に手や荷物などが引き込まれた場合、ドア閉安全装置またはドア開安全装置が動作し、引き込み状態を解除するためかごドアを反転して開閉動作を行うようにしている。また、ドア閉安全装置とドア開安全装置が共に動作した場合，ドア開動作が優先されるように構成されている。しかし、不用意にドアを通常速度で反転して完全に閉じてしまうと、引き込みを解消しようと努力している状況で、今度は反転動作したかごドアで予期しないトラブルが発生してしまう可能性があるもある。しかし、かごドアを自閉力とバランスするだけの戸開き力をかけた状態とすることにより、誰でも容易に引き込みを解消することができるようになる。   When a passenger in the vicinity of a car door pulls in a hand or baggage during the door opening / closing operation, the door closing safety device or the door opening safety device operates, and the car door is reversed to open / close the door to release the drawing state. I am doing so. Further, when both the door closing safety device and the door opening safety device are operated, the door opening operation is prioritized. However, if the door is inadvertently reversed at its normal speed and completely closed, there is a possibility that unexpected trouble will occur in the car door that has been reversed this time, in a situation where efforts are made to eliminate the pull-in. There are also. However, by setting the car door to a state in which the door opening force that balances the self-closing force is applied, anyone can easily remove the pull-in.
