本発明は、エレベータードアの開閉に際して敷居溝に異物が挟まって開閉動作に支障を起こした状態を診断するエレベータードア用敷居溝異物診断装置に関する。 The present invention relates to an elevator door sill groove foreign object diagnostic apparatus for diagnosing a state in which a foreign object is caught in a sill groove when the elevator door is opened and closed, which hinders the opening and closing operation.
従来、エレベーターでは、乗りかごが着床階でドア開閉を行う際、エレベータードア（具体的には乗りかごに設けられたかごドアや乗場階の出入口に設けられた乗場ドアを示す）の敷居溝に異物が挟まると、開閉動作を行うことができなくなり、こうした状況になれば同一階で開閉動作を繰り返すか、或いは一定時限後に開状態を維持したまま待機してサービスを停止してしまうため、利用者の利便性を損う事態となってしまう。 Conventionally, in elevators, when the car opens and closes on the landing floor, the elevator door (specifically, the car door provided on the car or the landing door provided at the entrance of the landing floor) If a foreign object gets caught in the door, the opening / closing operation cannot be performed, and if this happens, the opening / closing operation is repeated on the same floor, or the service is stopped after waiting for a certain period of time to remain open. It will be a situation that impairs user convenience.
そこで、こうした事態を回避するための技術が提案されており、例えば遠隔地からエレベーターの各階ドアの開閉点検を実施し、事前にエレベータードアの開閉異常を検知し、ひいては安全を確保することができる「エレベータドアの遠隔点検オペレーションシステム」（特許文献１参照）等が挙げられる。 Therefore, a technique for avoiding such a situation has been proposed. For example, it is possible to check opening / closing of each floor door of the elevator from a remote location, detect an opening / closing abnormality of the elevator door in advance, and thus ensure safety. “Elevator door remote inspection operation system” (see Patent Document 1).
上述した特許文献１に係る技術では、エレベータードアを開閉する際のドアモータのトルク値を各階ドアについて計測し、予め定められたトルク判定閾値を超えた場合に異常と判定し、その判定結果を遠隔監視装置に通知するものであるが、このような機能によればエレベータードアの異常有無を判定するだけであり、例えばエレベータードアの開閉を繰り返すことで敷居溝に挟まった異物除去を試みるといった試行や機能がなく、異常を回避するまで状況が変わらないため、結果として、エレベーターの不稼動時間の増加やエレベーターを使用できないことによる利用者（顧客）への利便性の低下を招く事態を解消することができないという問題がある。 In the technology according to Patent Document 1 described above, the torque value of the door motor when opening and closing the elevator door is measured for each floor door, and when a predetermined torque determination threshold is exceeded, it is determined as abnormal, and the determination result is remotely Although it is to notify the monitoring device, according to such a function, it is only determined whether there is an abnormality in the elevator door, for example, an attempt to remove a foreign object caught in a sill groove by repeatedly opening and closing the elevator door, Since there is no function and the situation does not change until an abnormality is avoided, as a result, it is possible to eliminate the situation that increases the downtime of the elevator and reduces the convenience to the user (customer) due to the inability to use the elevator There is a problem that can not be.
本発明は、このような問題点を解決すべくなされたもので、その技術的課題は、ドア開閉動作に支障を来す敷居溝に挟まった異物を可能な限り除去する機能を持つエレベータードア用敷居溝異物診断装置を提供することにある。 The present invention has been made to solve such problems, and its technical problem is for elevator doors having a function to remove as much foreign matter as possible between the sill grooves that hinder door opening and closing operations.

And an elevator control device for instructing a control value of the drive amount by the door control device according to the Device, when detecting the foreign substance sill groove, calculates a door reversal position based on a door opening and closing positions of the torque current value and the door closing position detecting device door motor, when the door opening and closing operation is repeated a plurality of times When the door reversal position changes by a predetermined amount or more, the door opening / closing operation is continued, and when the door reversing position changes within the predetermined amount, the door opening / closing operation is stopped to determine whether or not the foreign matter can be removed. It is characterized by.
本発明によれば、上記構成により、ドア開閉動作に支障を来す敷居溝に挟まった異物を可能な限り除去する機能を持たせられるようになる。上記した以外の課題、構成及び効果は、以下の実施の形態の説明により明らかにされる。 According to the present invention, according to the above configuration, it is possible to provide a function of removing as much foreign matter as possible between the sill grooves that hinder the door opening and closing operation. Problems, configurations, and effects other than those described above will be clarified by the following description of embodiments.
以下に、本発明のエレベータードア用敷居溝異物診断装置について、実施例を挙げ、図面を参照して詳細に説明する。 Hereinafter, an elevator door sill groove foreign matter diagnostic apparatus according to the present invention will be described in detail with reference to the accompanying drawings.
図１は、本発明の実施例に係るエレベータードア用敷居溝異物診断装置の基本構成を含むエレベーターの乗りかごの着床階近傍の周辺機構を示す外観斜視図である。 FIG. 1 is an external perspective view showing a peripheral mechanism in the vicinity of the landing floor of an elevator car including the basic configuration of an elevator door sill foreign material diagnostic apparatus according to an embodiment of the present invention.
図１を参照すれば、エレベーターの乗りかごの着床階近傍の周辺機構は、略図する建物の昇降路における各階床間を昇降走行する乗りかご１と、乗りかご１の着床階に設けられて乗りかご１に設けられたかごドア４と連動する乗場ドア３と、乗場ドア３に連結されたドアハンガー５と、ドアハンガー５に連結されてドアレール２の上面に対して回転しながら乗場ドア３を移動させるハンガーローラ６と、乗りかご１に設けられたかごドア４の開閉動作を駆動するドアモータ１０と、乗りかご１の着床階の手前側から奥側へと延在して位置される敷居７と、敷居７の奥側に設けられて乗場ドア３の開閉移動をガイドする乗場ドア側敷居溝８と、敷居７の更に奥側に設けられてかごドア４の開閉移動をガイドするかごドア側敷居溝９と、ドアモータ１０と同期して回転しながらパルス信号を発信し、パルス信号を積算してエレベータードア（通常はかごドア４を示すが、これに連動する乗場ドア３を含むものとする）の移動量を測定することでエレベータードアのドア開閉位置を算出するドア開閉位置検出装置１１と、を備える他、ドアモータ１０の駆動量を制御するドア制御装置１２と、エレベーターの乗りかご１の走行動作を制御すると共に、ドア開閉位置検出装置１１からのドア開閉位置に応じてドア制御装置１２による駆動量の制御値を指令するエレベーター制御装置としての制御盤１３と、を含んで構成される。 Referring to FIG. 1, the peripheral mechanism in the vicinity of the landing floor of the elevator car is provided in the car 1 that moves up and down between the floors in the hoistway of the building and the landing floor of the car 1. A landing door 3 interlocked with the car door 4 provided in the car 1, a door hanger 5 connected to the landing door 3, and a landing door connected to the door hanger 5 while rotating with respect to the upper surface of the door rail 2 3, a hanger roller 6 that moves 3, a door motor 10 that drives the opening / closing operation of the car door 4 provided in the car 1, and a position extending from the near side to the far side of the landing floor of the car 1. A sill 7, a landing door side sill 8 provided on the back side of the sill 7 to guide the opening and closing movement of the landing door 3, and a back side of the sill 7 to guide the opening and closing movement of the car door 4. Car door side sill ditch 9 and door motor Transmitting a pulse signal while rotating in synchronism with 10 and integrating the pulse signal to measure the amount of movement of the elevator door (usually the car door 4 but including the landing door 3 linked thereto) The door opening / closing position detecting device 11 for calculating the door opening / closing position of the elevator door, and the door control device 12 for controlling the drive amount of the door motor 10, the traveling operation of the elevator car 1, and the door And a control panel 13 as an elevator control device that commands a control value of the drive amount by the door control device 12 in accordance with the door open / close position from the open / close position detection device 11.
このうち、制御盤１３は、ドア開閉位置検出装置１１及びドア制御装置１２と協働してエレベータードア用敷居溝異物診断装置として機能するもので、乗りかご１が着床階レベルにあって敷居溝（乗場ドア側敷居溝８やかごドア側敷居溝９を示す）に異物を検知した場合、ドアモータ１０のトルク電流値とドア開閉位置検出装置１１からのドア開閉位置とに基づいて異物の除去の可否を判定する。この制御盤１３では、ドアモータ１０のトルク電流値とドア開閉位置検出装置１１からのドア開閉位置とに基づいてドア反転位置を算出し、ドア開閉動作を複数回繰り返した際のドア反転位置が所定量以上で変化した場合にはドア開閉動作を継続し、所定量以内で変化した場合にはドア開閉動作を停止する。具体的に云えば、制御盤１３は、異物の検知に際して、後文で詳述するように、ドア開閉動作を継続させたときのドア開閉動作の可否の判定結果に応じて、ドア閉不可能で且つドア開不可能であれば異物を除去できないとみなしてドア制御装置１２による駆動を行わせずに一定時間経過後に図示されない通信接続可能な監視用装置（監視端末や管制センタを示す）へ発報を行い、ドア閉不可能で且つドア開可能であれば異物を除去できる可能性有りとみなしてドア開閉動作を規定回数繰り返した後にドア反転位置が変化していなければ異物を除去できないとみなしてドア制御装置１２による駆動を行わせずに一定時間経過後に監視用装置へ発報を行い、ドア反転位置が変化していれば再度ドア開閉動作を規定回数繰り返してからドア閉可能とならなければ異物を除去できないとみなしてドア制御装置１２による駆動を行わせずに一定時間経過後に監視用装置へ発報を行い、ドア閉可能となればエレベータードアが正常に開閉可能になった状態を確認した時点で異物が除去されたとみなして通常サービスを開始する。こうした制御を行うことにより、エレベータードアに過剰な負担をかけずに異物の除去機能を持たせられると共に、発報の伝達を受けた担当者が迅速に対応することができるようになる。 Among these, the control panel 13 functions as an elevator door sill groove foreign body diagnostic device in cooperation with the door opening / closing position detection device 11 and the door control device 12, and the car 1 is at the floor level. When a foreign object is detected in the groove (showing the landing door side sill groove 8 or the car door side sill groove 9), the removal of the foreign object based on the torque current value of the door motor 10 and the door opening / closing position from the door opening / closing position detection device 11 Determine whether or not. The control panel 13 calculates the door reversal position based on the torque current value of the door motor 10 and the door open / close position from the door open / close position detection device 11, and determines the door reverse position when the door open / close operation is repeated a plurality of times. The door opening / closing operation is continued when the amount changes more than the predetermined amount, and the door opening / closing operation is stopped when the amount changes within a predetermined amount. More specifically, when detecting a foreign object, the control panel 13 cannot close the door according to the determination result of whether the door opening / closing operation is permitted or not when the door opening / closing operation is continued, as will be described in detail later. If the door cannot be opened, it is assumed that the foreign matter cannot be removed, and the door is not driven by the door control device 12, and after a certain time has elapsed, a communication-connectable monitoring device (showing a monitoring terminal and a control center) is shown. If the door is not closed and the door can be opened, it is considered that there is a possibility that the foreign object can be removed. Assuming that the door control device 12 is not driven, a warning is issued to the monitoring device after a predetermined time has elapsed, and if the door reversal position has changed, the door opening / closing operation is repeated a specified number of times and then the door can be closed. Otherwise, it is considered that the foreign matter cannot be removed, and the door control device 12 is not driven, but a warning is issued to the monitoring device after a certain period of time. If the door can be closed, the elevator door can be normally opened and closed. When the status is confirmed, it is assumed that the foreign matter has been removed, and the normal service is started. By performing such control, the elevator door can be provided with a foreign matter removing function without imposing an excessive burden, and the person in charge who has received the notification can respond quickly.
図２は、上述したエレベータードア用敷居溝異物診断装置に備えられるドア制御装置１２による制御対象となるドアモータ１０のトルク電流とドア開閉時間との相関を表わす特性図であり、同図（ａ）はドア閉動作が正常な場合のドアが閉じ始めてから閉まるまでの時間的変化を示す特性図、同図（ｂ）はドア閉動作が異常な場合の一例に係るトルク電流値がドア閉じの途中で急激に上昇した後に一定時間、且つ一定の大きさのトルク電流値をドアモータに供給した状態でドアが反転して開いた場合の特性図、同図（ｃ）はドア閉動作が異常な場合の他例に係るトルク電流値が緩やかに変化した後に一定時間、且つ一定の大きさのトルク電流値をドアモータに供給した状態でドアが反転して開いた場合の特性図である。 FIG. 2 is a characteristic diagram showing the correlation between the torque current of the door motor 10 to be controlled by the door control device 12 provided in the above-described elevator door sill groove foreign matter diagnostic apparatus and the door opening / closing time. Is a characteristic diagram showing a time change from when the door starts to close when the door closing operation is normal, and FIG. 5B is a diagram illustrating a case where the torque current value according to an example when the door closing operation is abnormal is during the door closing. Figure (c) is a characteristic diagram when the door is reversed and opened for a certain period of time after a sudden rise in the state of supplying a torque current value of a certain magnitude to the door motor. FIG. 10 is a characteristic diagram when the door is reversed and opened in a state where a torque current value having a constant magnitude is supplied to the door motor after the torque current value according to another example is gently changed.
図２（ａ）を参照すれば、ドア閉動作が正常な場合では、ドアモータ１０によるエレベータードアの開閉駆動時に発生するドアモータ１０のトルク電流が特性上で反転せず、エレベータードアが閉じ始めてから閉まるまでのドア開閉時間の経過に応じて次第に増加してピークを過ぎると急峻に減少し、その後はほぼ一定値を保持してから緩やかに減少する傾向を示す。 Referring to FIG. 2A, when the door closing operation is normal, the torque current of the door motor 10 generated when the door motor 10 is driven to open and close the elevator door does not reverse in terms of characteristics, and the elevator door closes after it starts to close. Gradually increases with the passage of the door opening / closing time until the peak is reached, then decreases sharply, and thereafter maintains a substantially constant value and then gradually decreases.
これに対し、図２（ｂ）を参照すれば、ドア閉動作が異常な場合の一例では、ドアモータ１０によるエレベータードアの開閉駆動時に発生するドアモータ１０のトルク電流が特性上で反転する一形態を示しており、具体的にはエレベータードアが閉じの途中でトルク電流値が急激に上昇した後に制御盤１３により一定時間、且つ一定の大きさのトルク電流値をドア制御装置１２に指令してドアモータ１０に供給した状態でエレベータードアが反転して開いた様子を示している。こうした異物の検知状況において、制御盤１３は、ドア制御装置１２に指令してドア開閉動作を規定回数ｎ繰り返した後にドア開閉位置検出装置１１からのドア開閉位置に基づいてドア反転位置を算出した結果、ドア反転位置が変化していないか否かをドア制御装置１２を介して判定する。また、制御盤１３は、ドア制御装置１２に指令してドア開閉動作を規定回数ｎ繰り返してもこの状態が継続して実線で示すようにドア反転位置が変化しなければ、敷居溝（敷居７における乗場ドア側敷居溝８やかごドア側敷居溝９を示す）に挟まっている異物が硬い物体であると想定する。これに対し、点線で示されるトルク電流の特性は、ドア制御装置１２に指令してドア開閉動作を規定回数ｎ繰り返したときにドア反転位置が変化した様子を示しており、この場合には異物の位置が移動して異物が除去され得る可能性を示すことになるため、制御盤１３はドア制御装置１２に指令して継続してドア開閉動作を再度規定回数ｎ繰り返す処理へ移行する。 On the other hand, referring to FIG. 2B, in an example in which the door closing operation is abnormal, a form in which the torque current of the door motor 10 generated when the door motor 10 is driven to open and close the elevator door is reversed in terms of characteristics. Specifically, after the torque current value suddenly rises while the elevator door is closed, the control panel 13 instructs the door control device 12 to output a torque current value having a constant time and a constant magnitude to the door motor. 10 shows a state in which the elevator door is reversed and opened in a state where it is supplied to No. 10. In such a foreign object detection situation, the control panel 13 instructs the door control device 12 to repeat the door opening / closing operation a predetermined number of times n and then calculates the door inversion position based on the door opening / closing position from the door opening / closing position detection device 11. As a result, it is determined via the door control device 12 whether or not the door reversal position has changed. Further, the control panel 13 instructs the door control device 12 to repeat the door opening / closing operation n times, and if this state continues and the door reversal position does not change as indicated by the solid line, the sill groove (the sill 7 It is assumed that the foreign matter sandwiched between the landing door side sill groove 8 and the car door side sill groove 9 in FIG. On the other hand, the torque current characteristic indicated by the dotted line indicates that the door reversal position has changed when the door control device 12 is commanded and the door opening / closing operation is repeated a predetermined number of times n. Therefore, the control panel 13 instructs the door control device 12 to continue and repeats the door opening / closing operation n times the specified number of times.
更に、制御盤１３は、敷居溝に挟まっている異物が硬い物体であると想定し、ドア反転位置が変化しない判定を行った場合には、敷居溝から異物を除去できないとみなしてドア制御装置１２による駆動を行わせずに一定時間経過後に監視用装置へ発報を行う。このように、制御盤１３ではドア制御装置１２に指令して或る規定回数ｎドア開閉動作を繰り返してもドア反転位置の状況が変わらない場合には、図示されない発報装置に指令して図示されない通信回線（電話回線やブロードバンド回線等）を介して監視用装置に発報して伝達する。発報の伝達を受けた担当者は、専門技術者を出動させてエレベータードアのドア開閉状態の確認又は対応策を検討するか、若しくは管理人室へ直接連絡して対応を促すことになる。こうした制御を行えば、硬い異物を除去できない場合には無理にエレベータードアのドア開閉動作を継続させずに発報の伝達を受けた担当者が迅速に対応することができる。 Further, the control panel 13 assumes that the foreign matter sandwiched in the sill groove is a hard object, and determines that the foreign matter cannot be removed from the sill groove when determining that the door inversion position does not change. No drive by 12 is performed and a warning is issued to the monitoring device after a certain time has elapsed. As described above, if the control panel 13 instructs the door control device 12 to repeat the door opening / closing operation a predetermined number of times and the door reversal position does not change, the control panel 13 instructs the alarm device (not shown) to show it. Notification is transmitted to the monitoring device via a communication line (such as a telephone line or a broadband line) that is not used. The person in charge who has received the notification dispatches a specialist engineer to confirm the door open / closed state of the elevator door or to consider countermeasures, or to contact the manager room directly to promote the response. If such control is performed, if a hard foreign object cannot be removed, the person in charge who has received the notification can respond quickly without forcibly continuing the door opening / closing operation of the elevator door.
また、図２（ｃ）を参照すれば、ドア閉動作が異常な場合の他例では、ドアモータ１０によるエレベータードアの開閉駆動時に発生するドアモータ１０のトルク電流が特性上で反転する他形態を示しており、具体的にはエレベータードアが閉じの途中でトルク電流値が緩やかに上昇した後に制御盤１３により一定時間、且つ一定の大きさのトルク電流値をドア制御装置１２に指令してドアモータ１０に供給した状態でエレベータードアが反転して開いた様子を示している。こうした異物の検知状況において、制御盤１３は、ドア制御装置１２に指令してドア開閉動作を規定回数ｎ繰り返した後にドア開閉位置検出装置１１からのドア開閉位置に基づいてドア反転位置を算出した結果、ドア反転位置が変化していないか否かをドア制御装置１２を介して判定する。また、制御盤１３は、ドア制御装置１２に指令してドア開閉動作を規定回数ｎ繰り返してもこの状態が継続して実線で示すようにドア反転位置が変化していなければ異物を除去することが困難であると判定するが、点線で示すようにドア反転位置が変化していれば敷居溝（ここでも敷居７における乗場ドア側敷居溝８やかごドア側敷居溝９を示す）に挟まっている異物が柔らかな物体であると想定する。 In addition, referring to FIG. 2 (c), another example in which the door closing operation is abnormal shows another embodiment in which the torque current of the door motor 10 generated when the door motor 10 is driven to open and close the elevator door is reversed in terms of characteristics. Specifically, after the torque current value rises gently while the elevator door is closed, the control panel 13 instructs the door control device 12 to output a torque current value having a constant magnitude for a predetermined time. In this state, the elevator door is reversed and opened. In such a foreign object detection situation, the control panel 13 instructs the door control device 12 to repeat the door opening / closing operation a predetermined number of times n and then calculates the door inversion position based on the door opening / closing position from the door opening / closing position detection device 11. As a result, it is determined via the door control device 12 whether or not the door reversal position has changed. Further, even if the control panel 13 commands the door control device 12 and repeats the door opening / closing operation n times the specified number of times, this state continues and the foreign matter is removed if the door inversion position has not changed as indicated by the solid line. However, if the door reversal position has changed as shown by the dotted line, it is sandwiched by the sill groove (here again, the landing door side sill groove 8 and the car door side sill groove 9 in the sill 7 are shown). Assume that the foreign object is a soft object.
制御盤１３は、ドア反転位置が変化して敷居溝に挟まっている異物が柔らかな物体であると判定した場合には、更にドア制御装置１２に指令してドア開閉動作を再度規定回数ｎ繰り返し、ドア反転位置の状況変化の有無を確認し、変化がある場合にはエレベータードアが閉じ可能であるかの試行を繰り返し行うことになるが、ドア開閉動作を再度規定回数ｎ繰り返してもドア閉可能とならなければ異物を除去することが困難であると判定し、ドア制御装置１２による駆動を行わせずに一定時間経過後に監視用装置へ発報を行う。ここでも発報の伝達を受けた担当者は、専門技術者を出動させてドア開閉状態の確認又は対応策を検討するか、若しくは管理人室へ直接連絡して対応を促すことになる。こうした制御を行えば、柔らかい異物であっても除去できない場合には発報の伝達を受けた担当者が迅速に対応することができる。更に、制御盤１３は、上述した異物の種別の想定結果に拘らず、ドア制御装置１２に指令してドア開閉動作を継続する再度の規定回数ｎ繰り返しでドア閉可能となっても、エレベータードアが正常に開閉可能になった状態を確認できなければ（トルク電流が反転していれば）、エレベータードアが支障を来しているとみなして保守点検の保全上の理由により、同様にドア制御装置１２による駆動を行わせずに一定時間経過後に監視用装置へ発報を行う。こうした制御を行えば、仮に異物除去のためのドア開閉動作の継続によってエレベータードアの開閉動作に支障を来した場合においても発報の伝達を受けた担当者が迅速に対応することができる。尚、ドア反転位置が変化しているか否かについては、エレベータードアのドア開閉動作を連続して所定回数行った際に、所定量以上動いたかで判定しても良いし、連続して所定回数行った後に、所定の位置を超えたか否かで判定しても良い。また、異物が柔らかいか否かについては、トルク電流の立ち上がりの変化量によって判断しても良い。更に、異物が硬い場合と柔らかい場合とで規定回数ｎの値や所定の長さ（位置）を異ならせても良い。例えば異物が硬い場合には、規定回数ｎや所定の長さを小さくすると機械保護の効果が得られる。 When the control panel 13 determines that the foreign matter sandwiched in the sill groove is a soft object by changing the door reversal position, the control panel 13 further instructs the door control device 12 to repeat the door opening and closing operation n times again. If there is a change in the situation of the door reversal position, and if there is a change, the trial will be repeated to see if the elevator door can be closed. If it is not possible, it is determined that it is difficult to remove the foreign matter, and the door control device 12 is not driven, and a notification is issued to the monitoring device after a predetermined time has elapsed. Here again, the person in charge who has received the notification sends out a specialist engineer to check the door open / closed state or consider a countermeasure, or directly contacts the manager's room to promote the response. If such control is performed, even if a soft foreign object cannot be removed, the person in charge who received the notification can quickly respond. In addition, the control panel 13 can be closed even if the door can be closed by repeating the prescribed number n of times for instructing the door control device 12 to continue the door opening / closing operation, regardless of the above-described assumption of the type of foreign matter. If it cannot be confirmed that the door can be opened and closed normally (if the torque current is reversed), the elevator door is considered to be in trouble and the door control is performed in the same way for maintenance reasons. Without the drive by the device 12, a warning is issued to the monitoring device after a certain time has elapsed. If such control is performed, even if the opening / closing operation of the elevator door is hindered due to the continuation of the door opening / closing operation for removing foreign matter, the person in charge who has received the notification can respond promptly. Whether or not the door reversing position has changed may be determined based on whether or not the door has moved more than a predetermined amount when the door opening / closing operation of the elevator door is continuously performed a predetermined number of times. After performing, it may be determined by whether or not a predetermined position is exceeded. Further, whether or not the foreign matter is soft may be determined by the amount of change in rising of the torque current. Further, the value of the specified number n and the predetermined length (position) may be different depending on whether the foreign matter is hard or soft. For example, when the foreign matter is hard, the effect of machine protection can be obtained by reducing the prescribed number n or the predetermined length.

図３を参照すれば、制御盤１３による動作処理では、まず乗りかご１が昇降路における各階床の着床階レベルにあるか否かの判定（ステップＳ１）を行う。この判定の結果、着床階レベルになければ、この判定（ステップＳ１）の処理前に戻って着床階レベルになるまで判定（ステップＳ１）を繰り返すが、着床階レベルにあれば、エレベータードアを閉じることができるか否かをドア閉不可能か否かの判定（ステップＳ２）により行う。この判定の結果、ドア閉不可能でなければ（ドア閉可能であれば）、最初の判定（ステップＳ１）の前に戻ってそれ以降の処理を繰り返すが、ドア閉不可能であれば、引き続いてエレベータードアを開くことができるか否かをドア開可能か否かの判定（ステップＳ３）により行う。因みに、ここでのエレベータードアについてのドア閉不可能か否かの判定（ステップＳ２）やドア開可能か否かの判定（ステップＳ３）でのドア開閉状態の確認は、制御盤１３の指令を受けたドア制御装置１２からのドア開閉指令に対し、エレベータードアの開端及び閉端に設置された図示されないドア開閉状態確認スイッチの作動状態、及びドア開閉時に駆動する図示されないベルトを駆動させるドアモータ１０と同期して回転するドア開閉位置検出装置１１によるドア開閉位置状態の合理性によりドア開閉可否が判断されるものである。 Referring to FIG. 3, in the operation process by the control panel 13, it is first determined whether or not the car 1 is at the landing level of each floor in the hoistway (step S1). If the result of this determination is that it is not at the landing floor level, the determination (step S1) is repeated until it reaches the landing floor level after returning to the processing of this determination (step S1). Whether the door can be closed is determined by determining whether the door cannot be closed (step S2). If the result of this determination is that the door cannot be closed (if the door can be closed), the process returns to before the first determination (step S1) and the subsequent processing is repeated. Whether or not the elevator door can be opened is determined by determining whether or not the door can be opened (step S3). Incidentally, the confirmation of the door open / closed state in the determination of whether or not the door can not be closed (step S2) and the determination of whether or not the door can be opened (step S3) here is based on a command from the control panel 13. In response to a door open / close command received from the door control device 12, the door motor 10 drives an unillustrated door open / close state confirmation switch installed at the open and closed ends of the elevator door and a belt (not shown) that is driven when the door is opened / closed. Whether the door is openable or not is determined based on the rationality of the door open / close position by the door open / close position detector 11 that rotates in synchronization with the door.
上述したドア開可能か否かの判定（ステップＳ３）の結果、ドア開可能でなければ（ドア開不可能であれば）、エレベータードアをドア開閉動作できない異常状態にあると判断し、ドア制御装置１２による駆動を行わせずに一定時間の経過を待つようにエレベータードアを駆動せずに待機（ステップＳ４）する処理へ移行し、一定時間後、発報装置に指令して監視用装置としての管制センタへ発報する（ステップＳ５）処理を行う。これにより、発報の伝達を受けた担当者は、専門技術者を出動させてドア開閉状態の確認又は対応策を検討するか、若しくは管理人室へ直接連絡して対応を促すのは上述した通りである。 As a result of the determination of whether or not the door can be opened (step S3), if the door cannot be opened (if the door cannot be opened), it is determined that the elevator door is in an abnormal state where the door cannot be opened and closed, and the door control is performed. The process proceeds to a process of waiting (step S4) without driving the elevator door so as to wait for the elapse of a certain time without driving by the device 12, and after a certain time, commanding the alarm device as a monitoring device. A process of issuing a notification to the control center (step S5) is performed. As described above, the person in charge who received the notification sent out a specialist engineer to check the door open / closed state or to consider countermeasures, or to contact the administrator room directly to encourage the action as described above. Street.
また、ドア開可能か否かの判定（ステップＳ３）の結果、ドア開可能であれば、エレベータードアが異常で例えば敷居溝に異物が挟まっていてもエレベータードアを正常なドア開閉動作に復旧できる余地があるとみなし、上述したステップＳ１からステップＳ３までの処理（ドア開閉動作）を規定回数繰り返す（ステップＳ６）処理の試行を行った後、ドア開閉位置検出装置１１からのドア開閉位置に基づいてエレベータードアの閉じる位置、即ち、ドア反転位置は変化しているか否かの判定（ステップＳ７）を行う。この判定の結果、ドア反転位置が変化していなければ、敷居溝に挟まっている異物が硬くて除去することが困難であるとみなしてドア制御装置１２による駆動を行わせずに一定時間の経過を待つようにエレベータードアを駆動せずに待機（ステップＳ４）する処理へ移行し、一定時間後、発報装置に指令して管制センタへ発報する（ステップＳ５）処理を行うが、ドア反転位置が変化していれば、敷居溝に挟まった異物が硬くても位置移動されたか、或いは柔らかい異物であって、エレベータードアを正常なドア開閉動作に復旧できる余地があるとみなし、上述したステップＳ１からステップＳ３までの処理（ドア開閉動作）を再度規定回数繰り返す（ステップＳ８）処理の試行を行う。 As a result of determining whether or not the door can be opened (step S3), if the door can be opened, the elevator door can be restored to a normal door opening / closing operation even if the elevator door is abnormal and foreign matter is caught in the sill groove, for example. It is assumed that there is room, and after performing the above-described processing from step S1 to step S3 (door opening / closing operation) a predetermined number of times (step S6) and performing a processing trial, based on the door opening / closing position from the door opening / closing position detection device 11 Then, it is determined whether or not the position where the elevator door is closed, that is, the door reversing position is changed (step S7). As a result of this determination, if the door reversal position has not changed, it is considered that the foreign matter sandwiched between the sill grooves is hard and difficult to remove, and a certain time has elapsed without being driven by the door control device 12. The process proceeds to a process of waiting without driving the elevator door (step S4) so as to wait, and after a certain period of time, a process is issued to the control center to issue a notification to the control center (step S5). If the position has changed, it is considered that the foreign object sandwiched in the sill groove is moved even if it is hard, or it is a soft foreign object, and there is room to restore the elevator door to normal door opening / closing operation, and the above-described steps The process from S1 to step S3 (door opening / closing operation) is repeated a specified number of times again (step S8).
この後、再びエレベータードアを閉じることができたか否かの判定（ステップＳ９）を行う。この判定の結果、エレベータードアを閉じることができなければ、敷居溝に挟まった異物を除去できないとみなし、ドア制御装置１２による駆動を行わせずに一定時間の経過を待つようにエレベータードアを駆動せずに待機（ステップＳ４）する処理へ移行し、一定時間後、発報装置に指令して管制センタへ発報する（ステップＳ５）処理を行うが、エレベータードアを閉じることができれば、異物が除去されたか否かを確認するためにエレベータードアを正常に開閉可能か否かを確認する判定（ステップＳ１０）を行う。この判定の結果、トルク電流の反転が解消されずにエレベータードアを正常に開閉可能でなければ、エレベータードアのドア開閉動作に支障を来しているとみなしてドア制御装置１２による駆動を行わせずに一定時間の経過を待つようにエレベータードアを駆動せずに待機（ステップＳ４）する処理へ移行し、一定時間後、発報装置に指令して管制センタへ発報する（ステップＳ５）処理を行うが、エレベータードアを正常に開閉可能であれば、敷居溝の異物が除去されたとみなして通常サービスを開始する（ステップＳ１１）ようにしてから動作処理を終了する。 Thereafter, it is determined whether or not the elevator door can be closed again (step S9). If the result of this determination is that the elevator door cannot be closed, it is assumed that the foreign matter caught in the sill groove cannot be removed, and the elevator door is driven so as to wait for a certain period of time without being driven by the door control device 12. The process proceeds to a process of waiting (step S4) without performing a process, and after a certain period of time, a command is issued to the alarm device and a report is issued to the control center (step S5). In order to confirm whether or not it has been removed, a determination is made to confirm whether or not the elevator door can be normally opened and closed (step S10). As a result of the determination, if the reversal of the torque current is not resolved and the elevator door cannot be opened and closed normally, it is assumed that the door opening / closing operation of the elevator door is hindered and the door control device 12 is driven. The process proceeds to a process of waiting without driving the elevator door (step S4) so as to wait for a certain period of time to elapse, and after a certain period of time, a command is issued to the alarm device and a report is issued to the control center (step S5). However, if the elevator door can be normally opened and closed, it is considered that the foreign matter in the sill groove has been removed, and the normal service is started (step S11), and the operation process is terminated.
以上に説明した通り、実施例に係るエレベータードア用敷居溝異物診断装置によれば、制御盤１３がエレベータードア下部における敷居溝（敷居７の乗場ドア側敷居溝８やかごドア側敷居溝９）に異物を検知すると、ドアモータ１０のトルク電流値とドア開閉位置検出装置１１からのドア開閉位置とに基づいて異物の除去の可否を判定すべく、ドア制御装置１２に指示してドア開閉動作を継続させて規定回数繰り返した後にドア開閉動作の可否を判定する処理を行うため、ドア開閉動作に支障を来す敷居溝に挟まった異物を可能な限り除去する機能を持たせられるようになる。 As described above, according to the elevator door sill groove foreign object diagnostic apparatus according to the embodiment, the control panel 13 is provided with a sill groove at the lower part of the elevator door (the landing door side sill groove 8 of the sill 7 and the car door side sill groove 9). When a foreign object is detected, the door controller 12 is instructed to perform door opening / closing operation in order to determine whether or not the foreign object can be removed based on the torque current value of the door motor 10 and the door opening / closing position from the door opening / closing position detection device 11. Since the process for determining whether or not the door opening / closing operation is permitted is performed after being continued and repeated for a specified number of times, it is possible to provide a function of removing as much foreign matter as possible between the sill grooves that interfere with the door opening / closing operation.
尚、実施例では図１を参照して説明した乗りかご１が１系統のエレベーターへの適用について説明したが、乗りかご１が２系統以上で並設される構成のエレベーターにも同様に適用できるため、本発明のエレベータードア用敷居溝異物診断装置は実施例で開示した形態に限定されない。 In the embodiment, the application of the car 1 described with reference to FIG. 1 to an elevator of one system has been described, but the present invention can be similarly applied to an elevator having a structure in which the car 1 is arranged in two or more systems.
