Description

エレベータの位置検出装置Elevator position detection device
　この発明は、かごの位置を検出するためのエレベータの位置検出装置に関するものである。 This invention relates to an elevator position detecting device for detecting the position of a car.
　従来、かごの着床位置を検出するために、水平方向へ互いに間隔を置いて配置された２つの検出板を昇降路の内壁側に取り付け、一方の検出板を検出するための２つの第１着床検出器と、他方の検出板を検出するための１つの第２着床検出器とを乗かご側に取り付けたエレベータの着床位置検出装置が提案されている。各第１着床検出器は、上下方向へ互いに間隔を置いて配置されている。この従来のエレベータの着床位置検出装置では、エレベータの乗かご側の床面と乗場側の床面とが合致したときに、各第１着床検出器が一方の検出板に対向し、第２着床検出器が他方の検出板に対向する。これにより、各着床検出器が作動し、かごの着床位置が検出される（特許文献１参照）。 Conventionally, in order to detect the landing position of a car, two detection plates that are spaced apart from each other in the horizontal direction are attached to the inner wall side of the hoistway, and two first detection plates for detecting one detection plate are used. There has been proposed an elevator landing position detection device in which an landing detector and one second landing detector for detecting the other detection plate are mounted on the passenger car side. The first landing detectors are spaced apart from each other in the vertical direction. In this conventional elevator landing position detection device, when the elevator car floor and the landing floor coincide with each other, each first landing detector faces one detection plate, Two landing detectors face the other detection plate. Thereby, each landing detector operates and the landing position of the car is detected (see Patent Document 1).

　しかし、各検出板が水平方向へ互いに間隔を置いて配置されているので、昇降路の水平断面積に対する各検出板の設置スペースが大きくなってしまう。これにより、昇降路内に設置される機器のレイアウトの自由度が制限されてしまう。 However, since the detection plates are spaced apart from each other in the horizontal direction, the installation space for each detection plate with respect to the horizontal sectional area of the hoistway becomes large. Thereby, the freedom degree of the layout of the apparatus installed in a hoistway will be restrict | limited.
　また、従来のエレベータの着床位置検出装置では、各第１着床検出器による検出板の検出の有無によってかごが所定の着床位置にあるか否かを検出することができ、各第２着床検出器による検出板の検出の有無によって、所定の着床位置を含むドア開閉可能区間内にかごがあるか否かを検出することができる。 In addition, in the conventional elevator landing position detection device, whether or not the car is at a predetermined landing position can be detected based on whether or not the detection plate is detected by each first landing detector. Whether or not there is a car in the door openable / closable section including a predetermined landing position can be detected based on whether or not the detection plate is detected by the landing detector.
　しかし、かごが所定の着床位置から外れている場合には、ドア開閉可能区間内からかごが外れない限り、かごの位置が所定の着床位置からどの程度外れているのかを確認することができない。従って、かごの位置がドア開閉可能区間内にあっても、ドア開閉可能区間の長さによっては、かごが所定の着床位置から大きく外れていることがある。この場合には、エレベータの異常が発生しているおそれもあるので、かごを移動させてかごの位置を調整することは適切ではない。また、各国の法規によっては、かごの位置をかごの移動により調整可能な区間をドア開閉可能区間とは別に設定しなければならない場合もある。 However, if the car is out of the predetermined landing position, it is possible to check how far the car is out of the predetermined landing position unless the car is removed from the door opening / closing section. Can not. Therefore, even if the position of the car is within the door opening / closing section, depending on the length of the door opening / closing section, the car may be greatly deviated from the predetermined landing position. In this case, since there is a possibility that the abnormality of the elevator has occurred, it is not appropriate to adjust the position of the car by moving the car. Further, depending on the laws and regulations of each country, it may be necessary to set a section in which the position of the car can be adjusted by moving the car separately from the door opening / closing section.
　この発明は、上記のような課題を解決するためになされたものであり、昇降路の水平断面に対する占有面積の縮小化を図ることができ、また、かごの停止位置を調整可能な区間をドア開閉可能区間とは別に設定することができるエレベータの位置検出装置を得ることを目的とする。 The present invention has been made in order to solve the above-described problems, and can reduce the occupation area of the hoistway with respect to the horizontal cross section, and can also adjust the stop position of the car to the door. An object is to obtain an elevator position detection device that can be set separately from the openable and closable section.
　この発明によるエレベータの位置検出装置は、昇降路内及び昇降路内を移動されるかごのいずれか一方に設けられ、かごの移動方向について所定の長さを持つ被検出体、かごの移動方向に沿ってそれぞれ間隔を置いて配置され、かつ被検出体に対向することにより検出動作をそれぞれ行う一対の着床位置センサ、一対の床合わせ位置センサ及びドア開閉位置センサを有し、昇降路内及びかごのいずれか他方に設けられ、各着床位置センサ間に各床合わせ位置センサが配置され、各床合わせ位置センサ間にドア開閉位置センサが配置された検出器、及び検出器からの情報を処理する処理部を備え、所定のかご着床区間からかごの位置が外れることにより、各着床位置センサのいずれかの検出動作が停止され、かご着床区間に隣接する床合わせ運転可能区間からかごの位置が外れることにより、各床合わせ位置センサのいずれかの検出動作が停止され、かご着床区間と床合わせ運転可能区間とを含むドア開閉可能区間からかごの位置が外れることにより、ドア開閉位置センサの検出動作が停止されるものである。 An elevator position detection apparatus according to the present invention is provided in either a hoistway or a car that is moved in a hoistway, and has a predetermined length in the moving direction of the car, in the moving direction of the car. And a pair of landing position sensors, a pair of floor alignment position sensors, and a door opening / closing position sensor, each of which is arranged to be spaced apart from each other and perform a detection operation by facing the object to be detected. A detector provided on the other side of the car, each floor alignment position sensor is disposed between each landing position sensor, and a door opening / closing position sensor is disposed between each floor alignment position sensor, and information from the detector A processing unit for processing is provided, and when the position of the car deviates from a predetermined car landing section, the detection operation of any of the landing position sensors is stopped, and the floor adjacent to the car landing section is aligned. When the position of the car deviates from the rollable section, the detection operation of one of the floor alignment position sensors is stopped, and the position of the car deviates from the door opening / closing section including the car landing section and the floor alignment operable section. As a result, the detection operation of the door opening / closing position sensor is stopped.
　この発明によるエレベータの位置検出装置では、各着床位置センサ、各床合わせ位置センサ及びドア開閉位置センサがかごの移動方向に沿ってそれぞれ間隔を置いて配置されているので、昇降路の水平断面に対する占有面積の縮小化を図ることができる。また、床合わせ運転可能区間からかごの位置が外れることにより、各床合わせ位置センサのいずれかの検出動作が停止され、ドア開閉可能区間からかごの位置が外れることにより、ドア開閉位置センサの検出動作が停止されるので、床合わせ運転可能区間をドア開閉可能区間とは別に設定することができる。従って、床合わせ運転可能区間をドア開閉可能区間よりも狭く設定することにより、かごの位置の調整が可能な区間を制限することができる。従って、かごの停止位置が大きくずれてエレベータの異常が発生している可能性が高い場合に、かごの移動による故障の拡大を防止することができる。 In the elevator position detection apparatus according to the present invention, each landing position sensor, each floor alignment position sensor, and door opening / closing position sensor are arranged at intervals along the moving direction of the car. It is possible to reduce the area occupied by In addition, when the car is moved from the section where the floor can be operated, the detection operation of any of the floor position sensors is stopped, and when the car is moved from the door openable section, the door opening / closing position sensor is detected. Since the operation is stopped, the floor matching operation possible section can be set separately from the door opening and closing section. Therefore, the section in which the position of the car can be adjusted can be limited by setting the floor-matching operable section narrower than the door opening and closing section. Therefore, when there is a high possibility that the car stop position is greatly deviated and an elevator abnormality has occurred, it is possible to prevent the failure from expanding due to the movement of the car.

　以下、この発明の好適な実施の形態について図面を参照して説明する。
　実施の形態１．
　図１は、この発明の実施の形態１によるエレベータを示す水平断面図である。図において、昇降路１内には、かご２及び釣合おもり３が昇降可能に設けられている。また、昇降路１内には、かご２を案内する一対のかごガイドレール４と、釣合おもり３を案内する一対の釣合おもりガイドレール５とが設けられている。かご２及び釣合おもり３は、図示しない巻上機（駆動装置）の駆動力により昇降路１内を昇降される。かご２及び釣合おもり３が昇降路１内を昇降されるときには、かご２は各かごガイドレール４に案内され、釣合おもり３は各釣合おもりガイドレール５に案内される。なお、各かごガイドレール４は、昇降路１の内壁面に固定されたブラケット６に固定されている。 Preferred embodiments of the present invention will be described below with reference to the drawings.
Embodiment 1 FIG.
1 is a horizontal sectional view showing an elevator according to Embodiment 1 of the present invention. In the figure, a car 2 and a counterweight 3 are provided in the hoistway 1 so as to be able to move up and down. Further, a pair of car guide rails 4 for guiding the car 2 and a pair of counterweight guide rails 5 for guiding the counterweight 3 are provided in the hoistway 1. The car 2 and the counterweight 3 are moved up and down in the hoistway 1 by a driving force of a hoisting machine (drive device) (not shown). When the car 2 and the counterweight 3 are moved up and down in the hoistway 1, the car 2 is guided to each car guide rail 4, and the counterweight 3 is guided to each counterweight guide rail 5. Each car guide rail 4 is fixed to a bracket 6 fixed to the inner wall surface of the hoistway 1.
　かご２には、一対のかごドア７により開閉可能なかご出入口８が設けられている。また、かご２には、各かごドア７を水平方向へ移動させるためのドア駆動装置（図示せず）が搭載されている。かご出入口８は、各かごドア７の水平方向への移動により開閉される。 The car 2 is provided with a car doorway 8 that can be opened and closed by a pair of car doors 7. Further, the car 2 is equipped with a door drive device (not shown) for moving each car door 7 in the horizontal direction. The car doorway 8 is opened and closed by the movement of each car door 7 in the horizontal direction.
　各階には、昇降路１内と乗場９とを連通する乗場出入口１０が設けられている。乗場出入口１０には、乗場出入口１０を開閉可能な一対の乗場ドア１１が設けられている。乗場出入口１０は、各乗場ドア１１の水平方向への移動により開閉される。 On each floor, there is a hall entrance 10 that connects the hoistway 1 and the hall 9. The landing entrance 10 is provided with a pair of landing doors 11 that can open and close the landing entrance 10. The landing entrance 10 is opened and closed by the horizontal movement of each landing door 11.
　かごドア７及び乗場ドア１１のそれぞれには、かごドア７及び乗場ドア１１を水平方向について互いに係合させるための係合装置（図示せず）が設けられている。かごドア７及び乗場ドア１１は、かご２が所定のドア開閉可能区間にあるときにのみ、係合装置により互いに係合される。従って、かご２がドア開閉可能区間のいずれの位置にあるときでも、かごドア７及び乗場ドア１１が水平方向について互いに係合される。 Each of the car door 7 and the landing door 11 is provided with an engagement device (not shown) for engaging the car door 7 and the landing door 11 with each other in the horizontal direction. The car door 7 and the landing door 11 are engaged with each other by the engaging device only when the car 2 is in a predetermined door opening / closing section. Accordingly, the car door 7 and the landing door 11 are engaged with each other in the horizontal direction regardless of the position of the car 2 in the door opening / closing section.
　各乗場ドア１１は、かご２がドア開閉可能区間にあるとき、各かごドア７の水平方向への移動により、かごドア７に係合されながら各かごドア７とともに移動される。かご出入口８及び乗場出入口１０は、各かごドア７及び各乗場ドア１１の移動により同時に開閉される。 Each landing door 11 is moved together with each car door 7 while being engaged with the car door 7 by the movement of each car door 7 in the horizontal direction when the car 2 is in the door openable / closable section. The car doorway 8 and the landing doorway 10 are simultaneously opened and closed by the movement of the car doors 7 and the landing doors 11.
　エレベータの運転は、図示しない制御装置により制御される。かご２の停止位置は、制御装置による巻上機の制御により、所定のかご着床区間内に調整される。かご着床区間は、ドア開閉可能区間内に設定されている。また、かご着床区間の長さは、ドア開閉可能区間の長さよりも短くされている。これにより、かご２が各階に着床しているときに、かご２の床面が乗場９の床面に対して大きくずれることが防止される。 The operation of the elevator is controlled by a control device (not shown). The stop position of the car 2 is adjusted within a predetermined car landing section under the control of the hoisting machine by the control device. The car landing section is set within the door opening and closing section. Further, the length of the car landing section is shorter than the length of the door opening / closing section. Thereby, when the car 2 is landing on each floor, the floor surface of the car 2 is prevented from being largely shifted from the floor surface of the landing 9.
　ドア開閉可能区間内には、かご２の移動方向についてかご着床区間に隣接する所定の床合わせ運転可能区間が設定されている。この例では、床合わせ運転可能区間は、かご着床区間の上下にそれぞれ隣接している。即ち、かご着床区間及び各床合わせ運転可能区間は、ドア開閉可能区間に含まれている。 In the door openable / closable section, a predetermined floor-to-floor operable section adjacent to the car landing section is set in the moving direction of the car 2. In this example, the floor-to-floor operable sections are adjacent to each other above and below the car landing section. In other words, the car landing section and the sections where each floor can be operated are included in the door opening / closing section.
　かご２の停止位置がかご着床区間から外れて床合わせ運転可能区間にあるときには、制御装置による巻上機の制御により、かご２をかご着床区間へ移動させるための床合わせ運転が行われる。これにより、かご２の停止位置がかご着床区間に調整される。 When the stop position of the car 2 is out of the car landing section and is in a section where the floor can be operated, the floor alignment operation for moving the car 2 to the car floor section is performed by the control of the hoisting machine by the control device. . Thereby, the stop position of the car 2 is adjusted to the car landing section.
　かご２の停止位置がかご着床区間及び床合わせ運転可能区間のいずれからも外れているときには、制御装置の制御により、かご２の停止状態が維持される。 When the stop position of the car 2 is out of either the car landing section or the floor-to-floor operation enabled section, the stop state of the car 2 is maintained by the control of the control device.
　かご２及び一方のかごガイドレール４には、かご着床区間、床合わせ運転可能区間及びドア開閉可能区間のそれぞれにおけるかご２の有無を検出するための位置検出装置１２が設けられている。制御装置には、位置検出装置１２からの情報が送られる。制御装置は、位置検出装置１２からの情報に基づいて、巻上機を制御し、かご２の位置を調整する。 The car 2 and one car guide rail 4 are provided with a position detection device 12 for detecting the presence or absence of the car 2 in each of the car landing section, the floor-to-floor operation enabling section, and the door opening / closing enabling section. Information from the position detection device 12 is sent to the control device. The control device controls the hoisting machine based on the information from the position detection device 12 and adjusts the position of the car 2.
　図２は、図１のエレベータの位置検出装置１２を示す斜視図である。また、図３は、図２の位置検出装置１２の処理部を示す回路構成図である。図において、位置検出装置１２は、一方のかごガイドレール４に設けられたかご位置検出用プレート（被検出体）１３と、かご２に設けられ、かご２の移動方向についてかご位置検出用プレート１３に対する位置に応じた信号を発生する検出器１４と、検出器１４からの情報を処理する処理部１５とを有している。 FIG. 2 is a perspective view showing the elevator position detector 12 of FIG. FIG. 3 is a circuit configuration diagram showing a processing unit of the position detection device 12 of FIG. In the figure, a position detection device 12 includes a car position detection plate (detected body) 13 provided on one of the car guide rails 4 and a car position detection plate 13 provided on the car 2 in the moving direction of the car 2. The detector 14 generates a signal corresponding to the position of the detector 14 and the processing unit 15 that processes information from the detector 14.
　かご位置検出用プレート１３は、水平方向に沿って配置された複数の取付部材１６を介してかごガイドレール４に取り付けられている。これにより、かご位置検出用プレート１３は、かごガイドレール４から水平方向へ離れて配置されている。かご位置検出用プレート１３の長さは、所定の長さとされている。また、かご位置検出用プレート１３は、かご２の移動方向に沿って配置されている。さらに、かご位置検出用プレート１３は、例えば金属等の磁性材料により構成されている。 The car position detection plate 13 is attached to the car guide rail 4 via a plurality of attachment members 16 arranged along the horizontal direction. Thus, the car position detection plate 13 is disposed away from the car guide rail 4 in the horizontal direction. The car position detection plate 13 has a predetermined length. The car position detection plate 13 is arranged along the moving direction of the car 2. Furthermore, the car position detection plate 13 is made of a magnetic material such as metal.
　検出器１４は、一対の着床位置センサ（上部着床位置センサ１７及び下部着床位置センサ１８）、一対の床合わせ位置センサ（上部床合わせ位置センサ１９及び下部床合わせ位置センサ２０）及びドア開閉位置センサ２１を有している。各着床位置センサ１７，１８、各床合わせ位置センサ１９，２０及びドア開閉位置センサ２１は、かご２の移動方向に沿ってそれぞれ間隔を置いて一列に配置され、かつかご位置検出用プレート１３に対向することにより検出動作をそれぞれ行う。 The detector 14 includes a pair of landing position sensors (upper landing position sensor 17 and lower landing position sensor 18), a pair of floor alignment positions sensors (upper floor alignment position sensor 19 and lower floor alignment position sensor 20), and a door. An open / close position sensor 21 is provided. The landing position sensors 17, 18, the floor alignment position sensors 19, 20, and the door opening / closing position sensor 21 are arranged in a row at intervals along the moving direction of the car 2, and the car position detection plate 13. The detection operation is performed by facing each other.
　上部着床位置センサ１７及び下部着床位置センサ１８間には、上部床合わせ位置センサ１９及び下部床合わせ位置センサ２０が配置されている。また、上部床合わせ位置センサ１９及び下部床合わせ位置センサ２０間には、ドア開閉位置センサ２１が配置されている。各着床位置センサ１７，１８及び各床合わせ位置センサ１９，２０は、光学式のセンサとされている。ドア開閉位置センサ２１は、磁気式のセンサとされている。 Between the upper landing position sensor 17 and the lower landing position sensor 18, an upper floor alignment position sensor 19 and a lower floor alignment position sensor 20 are arranged. A door opening / closing position sensor 21 is disposed between the upper floor alignment position sensor 19 and the lower floor alignment position sensor 20. The landing position sensors 17 and 18 and the floor alignment position sensors 19 and 20 are optical sensors. The door opening / closing position sensor 21 is a magnetic sensor.
　各着床位置センサ１７，１８、各床合わせ位置センサ１９，２０及びドア開閉位置センサ２１は、水平方向について互いに対向する一対の対向部をそれぞれ有している。各対向部間の領域は、かご位置検出用プレート１３を検出する検出領域となっている。即ち、各着床位置センサ１７，１８、各床合わせ位置センサ１９，２０及びドア開閉位置センサ２１には、かご位置検出用プレート１３を検出する検出領域がそれぞれ設けられている。 The landing position sensors 17 and 18, the floor alignment position sensors 19 and 20, and the door opening / closing position sensor 21 have a pair of facing portions that face each other in the horizontal direction. The area between the facing portions is a detection area for detecting the car position detection plate 13. That is, each of the landing position sensors 17 and 18, each of the floor alignment position sensors 19 and 20, and the door opening / closing position sensor 21 is provided with a detection region for detecting the car position detection plate 13.
　かご位置検出用プレート１３は、かご２の移動により、各位置センサ１７～２１の検出領域にそれぞれ通過可能になっている。各位置センサ１７～２１は、かご位置検出用プレート１３の検出領域への挿入により、かご位置検出用プレート１３に対向する。 The car position detection plate 13 can pass through the detection areas of the position sensors 17 to 21 as the car 2 moves. Each position sensor 17 to 21 is opposed to the car position detection plate 13 by inserting the car position detection plate 13 into the detection region.
　磁気式のセンサ（即ち、ドア開閉位置センサ２１）の検出領域内には、磁界が形成されている。磁気式のセンサの検出領域にかご位置検出用プレート１３が挿入されると、かご位置検出用プレート１３によって磁束が遮断され、磁気式のセンサ内の接点が閉極動作（Ｏｎ動作）される。これにより、磁気式のセンサの検出動作が行われる。 A magnetic field is formed in the detection region of the magnetic sensor (that is, the door opening / closing position sensor 21). When the car position detection plate 13 is inserted into the detection area of the magnetic sensor, the magnetic flux is interrupted by the car position detection plate 13, and the contact in the magnetic sensor is closed (On operation). Thereby, the detection operation of the magnetic sensor is performed.
　光学式のセンサ（即ち、各着床位置センサ１７，１８及び各床合わせ位置センサ１９，２０）では、一方の対向部に投光部が設けられ、他方の対向部に受光部が設けられている。光学式のセンサは、投光部からの光を受光部によって受けているか否かを検出することにより、検出領域へのかご位置検出用プレート１３の挿入の有無を検出する。従って、光学式のセンサの検出領域にかご位置検出用プレート１３が挿入されると、かご位置検出用プレート１３によって投光部からの光が遮蔽され、光学式のセンサ内の接点が閉極動作（Ｏｎ動作）される。これにより、光学式のセンサの検出動作が行われる。 In the optical sensors (that is, the landing position sensors 17 and 18 and the floor alignment position sensors 19 and 20), a light projecting portion is provided in one facing portion, and a light receiving portion is provided in the other facing portion. Yes. The optical sensor detects whether or not the car position detection plate 13 is inserted into the detection region by detecting whether or not the light from the light projecting unit is received by the light receiving unit. Therefore, when the car position detection plate 13 is inserted into the detection area of the optical sensor, the light from the light projecting portion is shielded by the car position detection plate 13 and the contact in the optical sensor is closed. (On operation). Thereby, the detection operation of the optical sensor is performed.
　かご着床区間にかご２があるときには、各位置センサ１７～２１のそれぞれの検出領域にかご位置検出用プレート１３が挿入される。従って、このときには、各位置センサ１７～２１のそれぞれの検出動作が行われる。 When the car 2 is in the car landing section, the car position detection plate 13 is inserted into the detection area of each of the position sensors 17-21. Accordingly, at this time, the detection operations of the position sensors 17 to 21 are performed.
　かご２の位置が上側の床合わせ運転可能区間に存在するときには、上部着床位置センサ１７の検出領域へのかご位置検出用プレート１３の挿入のみが外れる。従って、このときには、上部着床位置センサ１７の検出動作のみが停止される。また、かご２の位置が下側の床合わせ運転可能区間に存在するときには、下部着床位置センサ１８の検出領域へのかご位置検出用プレート１３の挿入のみが外れる。従って、このときには、下部着床位置センサ１８の検出動作のみが停止される。即ち、かご着床区間からかご２の位置が外れることにより、各着床位置センサ１７，１８のいずれかの検出動作が停止される。 When the position of the car 2 exists in the upper floor alignment operation possible section, only the insertion of the car position detection plate 13 into the detection area of the upper landing position sensor 17 is released. Accordingly, at this time, only the detection operation of the upper landing position sensor 17 is stopped. Further, when the position of the car 2 exists in the lower floor alignment operation possible section, only the insertion of the car position detection plate 13 into the detection area of the lower landing position sensor 18 is released. Accordingly, at this time, only the detection operation of the lower landing position sensor 18 is stopped. That is, when the position of the car 2 deviates from the car landing section, the detection operation of one of the landing position sensors 17 and 18 is stopped.
　ドア開閉可能区間において、かご２の位置が上側の床合わせ運転可能区間から上方へ外れているときには、上部着床位置センサ１７及び上部床合わせ位置センサ１９のそれぞれの検出領域へのかご位置検出用プレート１３の挿入が外れる。従って、このときには、上部着床位置センサ１７に加えて上部床合わせ位置センサ１９の検出動作も停止される。また、ドア開閉可能区間において、かご２の位置が下側の床合わせ運転可能区間から下方へ外れているときには、下部着床位置センサ１８及び下部床合わせ位置センサ２０のそれぞれの検出領域へのかご位置検出用プレート１３の挿入が外れる。従って、このときには、下部着床位置センサ１８に加えて下部床合わせ位置センサ２０の検出動作も停止される。即ち、かご２の位置が床合わせ運転可能区間から外れることにより、各床合わせ位置センサ１９，２０のいずれかの検出動作が停止される。 In the door opening / closing section, when the position of the car 2 is deviated upward from the upper floor alignment operation enabled section, the car position detection to the respective detection areas of the upper floor alignment position sensor 17 and the upper floor alignment position sensor 19 The insertion of the plate 13 is released. Therefore, at this time, the detection operation of the upper floor alignment position sensor 19 in addition to the upper landing position sensor 17 is also stopped. Further, in the door opening / closing section, when the position of the car 2 deviates downward from the lower floor alignment operation enabled section, the car to the respective detection areas of the lower landing position sensor 18 and the lower floor alignment position sensor 20. The insertion of the position detection plate 13 is released. Accordingly, at this time, the detection operation of the lower floor alignment position sensor 20 in addition to the lower landing position sensor 18 is also stopped. That is, when the position of the car 2 deviates from the floor alignment operable section, the detection operation of any of the floor alignment position sensors 19 and 20 is stopped.
　また、かご２の位置がドア開閉可能区間から外れると、ドア開閉位置センサ２１の検出領域へのかご位置検出用プレート１３の挿入が外れる。従って、かご２の位置がドア開閉可能区間から外れることにより、ドア開閉位置センサ２１の検出動作が停止される。 Further, when the position of the car 2 is out of the door openable / closable section, the insertion of the car position detection plate 13 into the detection area of the door open / close position sensor 21 is released. Accordingly, the detection operation of the door opening / closing position sensor 21 is stopped when the position of the car 2 deviates from the door opening / closing section.
　処理部１５は、図３に示すように、各着床位置センサ１７，１８、各床合わせ位置センサ１９，２０及びドア開閉位置センサ２１のそれぞれの検出動作の有無に応じた信号を制御装置へ出力する。即ち、処理部１５は、ドア開閉位置センサ２１が検出動作（Ｏｎ動作）を行っているときにのみ、ドア開閉可能信号２２を出力する。また、処理部１５は、上部着床位置センサ（一方の着床位置センサ）１７と、上部及び下部床合わせ位置センサ１９，２０のうちの上部着床位置センサ１７から遠い側のセンサ（一方の床合わせ位置センサ）２０とがいずれも検出動作（Ｏｎ動作）を行っているときにのみ、下側床合わせ位置信号（第１床合わせ位置信号）２３を出力し、下部着床位置センサ１８と、上部及び下部床合わせ位置センサ１９，２０のうちの下部着床位置センサ１８から遠い側のセンサ（他方の床合わせ位置センサ）１９とがいずれも検出動作（Ｏｎ動作）を行っているときにのみ、上側床合わせ位置信号（第２床合わせ位置信号）２４を出力する。ドア開閉可能信号２２、下側床合わせ位置信号２３及び上側床合わせ位置信号２４は、処理部１５から制御装置へ送られる。 As shown in FIG. 3, the processing unit 15 sends signals to the control device according to the presence / absence of detection operations of the landing position sensors 17 and 18, the floor alignment position sensors 19 and 20, and the door opening / closing position sensor 21. Output. That is, the processing unit 15 outputs the door opening / closing enable signal 22 only when the door opening / closing position sensor 21 is performing a detection operation (On operation). Further, the processing unit 15 includes an upper landing position sensor (one landing position sensor) 17 and a sensor farther from the upper landing position sensor 17 among the upper and lower floor alignment position sensors 19 and 20 (one of the landing positions sensor). Only when both the floor alignment position sensor) 20 are performing the detection operation (On operation), the lower floor alignment position signal (first floor alignment position signal) 23 is output, When the sensor (the other floor alignment position sensor) 19 far from the lower landing position sensor 18 among the upper and lower floor alignment position sensors 19 and 20 is performing a detection operation (On operation). Only, the upper floor alignment position signal (second floor alignment position signal) 24 is output. The door opening / closing enable signal 22, the lower floor alignment position signal 23, and the upper floor alignment position signal 24 are sent from the processing unit 15 to the control device.
　制御装置は、ドア開閉可能信号２２、下側床合わせ位置信号２３及び上側床合わせ位置信号２４のそれぞれ（位置検出装置１２からの情報）を受信可能になっている。制御装置は、ドア開閉可能信号２２、下側床合わせ位置信号２３及び上側床合わせ位置信号２４のそれぞれの受信の有無を検出することにより、かご着床区間、床合わせ運転可能区間及びドア開閉可能区間のそれぞれにおけるかご２の有無を判定する。 The control device can receive each of the door opening / closing enable signal 22, the lower floor alignment position signal 23, and the upper floor alignment position signal 24 (information from the position detection device 12). The control device detects the presence / absence of reception of the door opening / closing enable signal 22, the lower floor alignment position signal 23, and the upper floor alignment position signal 24, so that the car landing section, the floor alignment operable section, and the door can be opened / closed. The presence / absence of the car 2 in each section is determined.
　即ち、制御装置は、ドア開閉可能信号２２を受けているときに、かご２がドア開閉可能区間にあると判定し、ドア開閉可能信号２２の受信が停止されているときに、かご２がドア開閉可能区間外にあると判定する。また、制御装置は、下側床合わせ位置信号２３及び上側床合わせ位置信号２４のいずれかを受けているときに、かご２が床合わせ運転可能区間にあると判定する。さらに、制御装置は、下側床合わせ位置信号２３及び上側床合わせ位置信号２４をいずれも受けているときに、かご２がかご着床区間にあると判定する。 That is, the control device determines that the car 2 is in the door openable / closable section when receiving the door openable / closable signal 22, and the car 2 is the door when reception of the door openable / closable signal 22 is stopped. It is determined that it is outside the openable / closable section. In addition, the control device determines that the car 2 is in the floor alignment operable section when receiving either the lower floor alignment position signal 23 or the upper floor alignment position signal 24. Furthermore, the control device determines that the car 2 is in the car landing section when both the lower floor alignment position signal 23 and the upper floor alignment position signal 24 are received.
　また、制御装置は、下側床合わせ位置信号２３の受信があり、かつ上側床合わせ位置信号２４の受信が停止されているときに、かご２がかご着床区間から下方へ外れて下側の床合わせ運転可能区間内にあると判定する。さらに、制御装置は、上側床合わせ位置信号２４の受信があり、かつ下側床合わせ位置信号２３の受信が停止されているときに、かご２がかご着床区間から上方へ外れて上側の床合わせ運転可能区間にあると判定する。 In addition, when the control apparatus receives the lower floor alignment position signal 23 and stops receiving the upper floor alignment position signal 24, the car 2 moves downward from the car landing section and moves downward. It is determined that the vehicle is within the floor-to-floor operable section. Furthermore, when the control apparatus receives the upper floor alignment position signal 24 and stops receiving the lower floor alignment position signal 23, the car 2 moves upward from the car landing section and moves to the upper floor. It is determined that the vehicle is in the combined operation possible section.
　次に、動作について説明する。図４は、図１のかご２が上昇しているときの各位置センサ１７～２１のそれぞれの動作、ドア開閉可能信号２２、下側床合わせ位置信号２３及び上側床合わせ位置信号２４の時間的変化を示すタイミングチャートである。図に示すように、かご２が階床に下方から近づくと、まず、上部着床位置センサ１７及び上部床合わせ位置センサ１９の順にかご位置検出用プレート１３が検出領域に挿入され、上部着床位置センサ１７及び上部床合わせ位置センサ１９の順にＯｎ動作（検出動作）が行われる。 Next, the operation will be described. FIG. 4 shows the operation of each of the position sensors 17 to 21 when the car 2 in FIG. 1 is rising, the door opening / closing enable signal 22, the lower floor alignment position signal 23, and the upper floor alignment position signal 24 over time. It is a timing chart which shows change. As shown in the figure, when the car 2 approaches the floor from below, first, the car position detection plate 13 is inserted into the detection area in the order of the upper landing position sensor 17 and the upper floor alignment position sensor 19, and the upper landing is performed. On operation (detection operation) is performed in the order of the position sensor 17 and the upper floor alignment position sensor 19.
　この後、かご２がさらに上昇し、ドア開閉位置センサ２１の検出領域にかご位置検出用プレート１３が挿入されると、ドア開閉可能信号２２が処理部１５から制御装置へ出力される。これにより、ドア開閉可能区間にかご２があるとの判定が制御装置により行われる。 Thereafter, when the car 2 further rises and the car position detection plate 13 is inserted into the detection area of the door open / close position sensor 21, a door open / close enable signal 22 is output from the processing unit 15 to the control device. Thus, the control device determines that the car 2 is in the door openable / closable section.
　この後、かご２がさらに上昇し、下部床合わせ位置センサ２０の検出領域にかご位置検出用プレート１３が挿入されると、ドア開閉可能信号２２の出力が維持されたまま、下側床合わせ位置信号２３が処理部１５から制御装置へ出力される。これにより、下側の床合わせ運転可能区間にかご２があるとの判定が制御装置により行われる。 Thereafter, when the car 2 further rises and the car position detection plate 13 is inserted into the detection area of the lower floor alignment position sensor 20, the output of the door open / close enable signal 22 is maintained and the lower floor alignment position is maintained. A signal 23 is output from the processing unit 15 to the control device. Accordingly, the control device determines that the car 2 is in the lower floor-to-floor operation enabled section.
　この後、かご２がさらに上昇し、下部着床位置センサ１８の検出領域にかご位置検出用プレート１３が挿入されると、ドア開閉可能信号２２及び下側床合わせ位置信号２３のそれぞれの出力が維持されたまま、上側床合わせ位置信号２４が処理部１５から制御装置へ出力される。これにより、かご２がかご着床区間にあるとの判定が制御装置により行われる。かご２は、制御装置による巻上機の制御により、かご着床区間内に位置を合わせて階床に停止される。 Thereafter, when the car 2 further rises and the car position detection plate 13 is inserted into the detection area of the lower landing position sensor 18, the respective outputs of the door open / close enable signal 22 and the lower floor alignment position signal 23 are output. The upper floor alignment position signal 24 is output from the processing unit 15 to the control device while being maintained. Thus, the control device determines that the car 2 is in the car landing section. The car 2 is stopped at the floor by matching the position in the car landing section under the control of the hoisting machine by the control device.
　この後、かご２が階床から上昇すると、上部着床位置センサ１７、上部床合わせ位置センサ１９、ドア開閉位置センサ２１、下部床合わせ位置センサ２０及び下部着床位置センサ１８の順にかご位置検出用プレート１３の挿入が外れる。これにより、下側床合わせ位置信号２３、上側床合わせ位置信号２４及びドア開閉可能信号２２の順に処理部１５からの出力が停止される。 Thereafter, when the car 2 rises from the floor, the car position is detected in the order of the upper landing position sensor 17, the upper floor alignment position sensor 19, the door opening / closing position sensor 21, the lower floor alignment position sensor 20, and the lower landing position sensor 18. Insertion of the working plate 13 is released. Accordingly, the output from the processing unit 15 is stopped in the order of the lower floor alignment position signal 23, the upper floor alignment position signal 24, and the door opening / closing enable signal 22.
　かご２が階床に停止されているときには、乗客のかご２に対する乗降や、かご２を吊り下げる主索の伸縮等により、かご２の停止位置がかご着床区間から外れることがある。また、昇降路内のセンサ等の不具合により、かご２の停止位置がかご着床区間及び床合わせ運転可能区間のいずれからも外れることがある。 When the car 2 is stopped on the floor, the stop position of the car 2 may deviate from the car landing section due to passengers getting on and off the car 2 and expansion / contraction of the main rope that suspends the car 2. Moreover, the stop position of the car 2 may deviate from both the car landing section and the floor-to-floor operation section due to problems such as sensors in the hoistway.
　かご２の停止位置が上側及び下側の床合わせ運転可能区間のいずれかにあるときには、制御装置による巻上機の制御により、かご２が移動され、かご２の停止位置がかご着床区間に調整される。即ち、ドア開閉可能信号２２及び下側床合わせ位置信号２３のそれぞれが制御装置によって受信されているときには、かご２がかご着床区間から下方へ外れているとの判定が制御装置により行われ、かご２が上方へ移動される。また、ドア開閉可能信号２２及び上側床合わせ位置信号２４のそれぞれが制御装置によって受信されているときには、かご２がかご着床区間から上方へ外れているとの判定が制御装置により行われ、かご２が下方へ移動される。 When the stop position of the car 2 is in one of the upper and lower floor-to-floor operable sections, the car 2 is moved by the control of the hoisting machine by the control device, and the stop position of the car 2 is moved to the car landing section. Adjusted. That is, when each of the door opening / closing enable signal 22 and the lower floor alignment position signal 23 is received by the control device, it is determined by the control device that the car 2 has fallen downward from the car landing section. The car 2 is moved upward. Further, when each of the door open / close enable signal 22 and the upper floor alignment position signal 24 is received by the control device, the control device determines that the car 2 has moved upward from the car landing section. 2 is moved downward.
　また、かご２の停止位置が大きくずれて、かご着床区間及び床合わせ運転可能区間のいずれからも外れているときには、制御装置による巻上機の制御により、かご２の移動は阻止され、かご２の停止が維持される。即ち、下側床合わせ位置信号２３及び上側床合わせ位置信号２４のいずれについても制御装置による受信が停止されているときには、制御装置の制御により、かご２が停止されたままとされる。 Further, when the stop position of the car 2 is greatly deviated and deviates from both the car landing section and the floor-to-floor operation enabled section, the movement of the car 2 is prevented by the control of the hoisting machine by the control device. 2 stops are maintained. That is, when the reception by the control device is stopped for both the lower floor alignment position signal 23 and the upper floor alignment position signal 24, the car 2 is kept stopped by the control of the control device.
　このようなエレベータの位置検出装置では、各着床位置センサ１７，１８、各床合わせ位置センサ１９，２０及びドア開閉位置センサ２１がかご２の移動方向に沿ってそれぞれ間隔を置いて配置されているので、昇降路１の水平断面に対する占有面積の縮小化を図ることができる。また、床合わせ運転可能区間からかご２の位置が外れることにより、各床合わせ位置センサ１９，２０のいずれかの検出動作が停止され、ドア開閉可能区間からかご２の位置が外れることにより、ドア開閉位置センサ２１の検出動作が停止されるので、床合わせ運転可能区間をドア開閉可能区間とは別に設定することができる。従って、床合わせ運転可能区間をドア開閉可能区間よりも狭く設定することにより、かご２の位置の調整が可能な区間を制限することができる。従って、かご２の停止位置が大きくずれてエレベータの異常が発生している可能性が高い場合に、かご２の移動による故障の拡大を防止することができる。 In such an elevator position detection apparatus, the landing position sensors 17 and 18, the floor alignment position sensors 19 and 20, and the door opening / closing position sensor 21 are arranged at intervals along the moving direction of the car 2. Therefore, the occupation area with respect to the horizontal cross section of the hoistway 1 can be reduced. Further, when the position of the car 2 is deviated from the section where the floor can be operated, the detection operation of one of the floor position sensors 19, 20 is stopped, and the position of the car 2 is deviated from the section where the door can be opened and closed. Since the detection operation of the opening / closing position sensor 21 is stopped, the floor matching operation possible section can be set separately from the door openable / closable section. Therefore, the section in which the position of the car 2 can be adjusted can be limited by setting the floor-matching operable section narrower than the door opening / closing section. Therefore, when there is a high possibility that the stop position of the car 2 is greatly deviated and an abnormality of the elevator has occurred, it is possible to prevent an increase in failure due to the movement of the car 2.
　また、ドア開閉位置センサ２１は、磁気式のセンサであるので、例えば火災時の煙や外光等の外乱による誤動作の防止を図ることができる。これにより、かご２がドア開閉可能区間から外れた位置にあるときにドア駆動装置を誤って駆動させることを防止することができる。 Further, since the door opening / closing position sensor 21 is a magnetic sensor, it is possible to prevent malfunction due to disturbance such as smoke or external light during a fire. Thereby, when the cage | basket | car 2 exists in the position which remove | deviated from the door opening / closing area | region, it can prevent driving a door drive device accidentally.
　また、各着床位置センサ１７，１８及び各床合わせ位置センサ１９，２０は、光学式のセンサであるので、かご位置検出用プレート１３の検出精度を向上させることができる。これにより、かご２の床面を乗場の床面に合わせる床合わせ運転を精度良く行うことができる。 Further, since the landing position sensors 17 and 18 and the floor alignment position sensors 19 and 20 are optical sensors, the detection accuracy of the car position detection plate 13 can be improved. Thereby, the floor matching operation | movement which matches the floor surface of the cage | basket | car 2 with the floor surface of a hall can be performed with sufficient precision.
　また、処理部１５は、上部着床位置センサ１７及び下部床合わせ位置センサ２０がいずれも検出動作を行っているときにのみ下側床合わせ位置信号２３を出力し、下部着床位置センサ１８及び上部床合わせ位置センサ１９がいずれも検出動作を行っているときにのみ上側床合わせ位置信号２４を出力するようになっており、下側床合わせ位置信号２３及び上側床合わせ位置信号２４のいずれかが処理部１５から出力されているときに、かご２が床合わせ運転可能区間にあることが検出されるので、かご２の位置がかご着床区間の上下いずれの側へ外れているのかを特定することができる。従って、かご２がかご着床区間から外れている方向を検出するセンサを新たに設けることなく、かご２をかご着床区間へ容易に移動させることができる。 Further, the processing unit 15 outputs the lower floor alignment position signal 23 only when both the upper landing position sensor 17 and the lower floor alignment position sensor 20 are performing the detection operation. The upper floor alignment position signal 24 is output only when both the upper floor alignment position sensors 19 are performing the detection operation, and either the lower floor alignment position signal 23 or the upper floor alignment position signal 24 is output. Is output from the processing unit 15, it is detected that the car 2 is in the section where the floor-to-floor operation is possible. Therefore, it is specified whether the position of the car 2 is deviated to the upper or lower side of the car landing section. can do. Therefore, the car 2 can be easily moved to the car landing section without newly providing a sensor for detecting the direction in which the car 2 is deviated from the car landing section.
　なお、上記の例では、ドア開閉位置センサ２１が磁気式のセンサとされているが、例えばかご位置検出用プレート１３に設けた磁石と、検出器に設けたコイルとを有し、電磁誘導を利用して検出動作を行う電磁式のセンサをドア開閉位置センサ２１としてもよい。このようにしても、煙や外光等の外乱による誤動作の防止を図ることができる。 In the above example, the door opening / closing position sensor 21 is a magnetic sensor. However, for example, the door opening / closing position sensor 21 includes a magnet provided on the car position detection plate 13 and a coil provided on the detector, and performs electromagnetic induction. An electromagnetic sensor that performs detection operation using the door may be used as the door opening / closing position sensor 21. Even in this case, it is possible to prevent malfunction due to disturbance such as smoke or external light.
　実施の形態２．
　図５は、この発明の実施の形態２によるエレベータの位置検出装置の処理部を示す回路構成図である。位置検出装置の処理部１５は、ドア開閉位置センサ２１が検出動作を行っているときにのみドア開閉可能信号２２を出力し、ドア開閉位置センサ２１、上部着床位置センサ１７及び下部床合わせ位置センサ２０がいずれも検出動作を行っているときにのみ下側床合わせ位置信号（第１床合わせ位置信号）２３を出力し、ドア開閉位置センサ２１、下部着床位置センサ１８及び上部床合わせ位置センサ１９がいずれも検出動作を行っているときにのみ上側床合わせ位置信号（第２床合わせ位置信号）２４を出力する。他の構成は実施の形態１と同様である。 Embodiment 2. FIG.
FIG. 5 is a circuit configuration diagram showing a processing unit of an elevator position detection apparatus according to Embodiment 2 of the present invention. The processing unit 15 of the position detection device outputs the door open / close enable signal 22 only when the door open / close position sensor 21 is performing the detection operation, and outputs the door open / close position sensor 21, the upper landing position sensor 17, and the lower floor alignment position. The lower floor alignment position signal (first floor alignment position signal) 23 is output only when the sensors 20 are performing detection operations, and the door opening / closing position sensor 21, the lower landing position sensor 18, and the upper floor alignment position are output. The upper floor alignment position signal (second floor alignment position signal) 24 is output only when any of the sensors 19 is performing a detection operation. Other configurations are the same as those in the first embodiment.
　このようなエレベータの位置検出装置では、ドア開閉位置センサ２１、上部着床位置センサ１７及び下部床合わせ位置センサ２０がいずれも検出動作を行っているときにのみ、下側床合わせ位置信号（第１床合わせ位置信号）２３が処理部１５から出力され、ドア開閉位置センサ２１、下部着床位置センサ１８及び上部床合わせ位置センサ１９がいずれも検出動作を行っているときにのみ、上側床合わせ位置信号（第２床合わせ位置信号）２４が処理部１５から出力されるので、例えば煙や外光等によって各着床位置センサ１７，１８や各床合わせ位置センサ１９，２０が誤動作を行った場合であっても、かご２がドア開閉可能区間から外れた位置にあるときには、下側床合わせ位置信号２３及び上側床合わせ位置信号２４が処理部１５から誤って出力されることを防止することができる。これにより、エレベータの運転の信頼性の向上を図ることができる。 In such an elevator position detection apparatus, only when the door opening / closing position sensor 21, the upper landing position sensor 17, and the lower floor alignment position sensor 20 are performing detection operations, the lower floor alignment position signal (first Only when the door opening / closing position sensor 21, the lower landing position sensor 18, and the upper floor alignment position sensor 19 are performing detection operations. Since the position signal (second floor alignment position signal) 24 is output from the processing unit 15, each landing position sensor 17, 18 or each floor alignment position sensor 19, 20 has malfunctioned due to, for example, smoke or external light. Even when the car 2 is at a position outside the door openable / closable section, the lower floor alignment position signal 23 and the upper floor alignment position signal 24 are processed by the processor 15. It can be prevented from being erroneously output. Thereby, the improvement of the reliability of operation of an elevator can be aimed at.

The landing position sensors 17 and 18 and the floor alignment position sensors 19 and 20 are arranged in a line at intervals along the moving direction of the car 2 and are detected by facing the car position detecting plate 13. Perform each action.
　上部着床位置センサ１７及び下部着床位置センサ１８間には、上部床合わせ位置センサ１９及び下部床合わせ位置センサ２０が配置されている。各着床位置センサ１７，１８は光学式のセンサとされ、各床合わせ位置センサ１９，２０は磁気式のセンサとされている。光学式及び磁気式のセンサのそれぞれの構成は実施の形態１と同様である。 Between the upper landing position sensor 17 and the lower landing position sensor 18, an upper floor alignment position sensor 19 and a lower floor alignment position sensor 20 are arranged. The landing position sensors 17 and 18 are optical sensors, and the floor alignment position sensors 19 and 20 are magnetic sensors. The configurations of the optical and magnetic sensors are the same as those in the first embodiment.
　かご着床区間にかご２があるときには、各位置センサ１７～２０のそれぞれがかご位置検出用プレート１３に対向している。従って、このときには、各位置センサ１７～２０のそれぞれの検出動作が行われる。 When the car 2 is in the car landing section, each of the position sensors 17 to 20 faces the car position detection plate 13. Accordingly, at this time, the detection operations of the position sensors 17 to 20 are performed.
　かご２の位置が上側床合わせ運転可能区間に存在するときには、上部着床位置センサ１７の検出動作のみが停止され、かご２の位置が下側床合わせ運転可能区間に存在するときには、下部着床位置センサ１８の検出動作のみが停止される。即ち、かご着床区間からかご２の位置が外れることにより、各着床位置センサ１７，１８のいずれかの検出動作が停止される。 When the position of the car 2 exists in the upper floor alignment operation possible section, only the detection operation of the upper landing position sensor 17 is stopped, and when the position of the car 2 exists in the lower floor alignment operation possible section, the lower landing Only the detection operation of the position sensor 18 is stopped. That is, when the position of the car 2 deviates from the car landing section, the detection operation of one of the landing position sensors 17 and 18 is stopped.
　ドア開閉可能区間において、かご２の位置が上側床合わせ運転可能区間から上方へ外れているときには、上部着床位置センサ１７に加えて上部床合わせ位置センサ１９の検出動作も停止される。また、ドア開閉可能区間において、かご２の位置が下側床合わせ運転可能区間から下方へ外れているときには、下部着床位置センサ１８に加えて下部床合わせ位置センサ２０の検出動作も停止される。即ち、かご２の位置が床合わせ運転可能区間から外れることにより、各床合わせ位置センサ１９，２０のいずれかの検出動作が停止される。 In the door openable / closable section, when the position of the car 2 deviates upward from the upper floor alignment operation possible section, the detection operation of the upper floor alignment position sensor 19 in addition to the upper floor alignment position sensor 17 is also stopped. Further, when the position of the car 2 deviates downward from the lower floor alignment operation enabled section in the door opening / closing section, the detection operation of the lower floor alignment position sensor 20 in addition to the lower landing position sensor 18 is also stopped. . That is, when the position of the car 2 deviates from the floor alignment operable section, the detection operation of any of the floor alignment position sensors 19 and 20 is stopped.
　また、かご２の位置がドア開閉可能区間から外れることにより、各床合わせ位置センサ１９，２０のいずれの検出動作も停止される。 Further, when the position of the car 2 deviates from the door opening / closing section, the detection operation of each of the floor alignment position sensors 19 and 20 is stopped.
　処理部１５は、図７に示すように、各床合わせ位置センサ１９，２０のそれぞれからの情報を処理するＯＲゲート２５を有している。これにより、処理部１５は、各床合わせ位置センサ１９，２０の少なくともいずれかが検出動作を行っているときにのみ、ドア開閉可能信号２２を出力する。また、処理部１５は、上部着床位置センサ１７及び下部床合わせ位置センサ２０がいずれも検出動作を行っているときにのみ、下側床合わせ位置信号２３を出力し、下部着床位置センサ１８及び上部床合わせ位置センサ１９がいずれも検出動作を行っているときにのみ、上側床合わせ位置信号２４を出力する。ドア開閉可能信号２２、下側床合わせ位置信号２３及び上側床合わせ位置信号２４は、処理部１５から制御装置へ送られる。他の構成は実施の形態１と同様である。 As shown in FIG. 7, the processing unit 15 has an OR gate 25 that processes information from each of the floor alignment position sensors 19 and 20. Thereby, the processing unit 15 outputs the door open / close enable signal 22 only when at least one of the floor alignment position sensors 19 and 20 is performing the detection operation. The processing unit 15 outputs the lower floor alignment position signal 23 only when both the upper landing position sensor 17 and the lower floor alignment position sensor 20 are performing the detection operation, and the lower landing position sensor 18 is output. The upper floor alignment position signal 24 is output only when both the upper floor alignment position sensor 19 is performing the detection operation. The door opening / closing enable signal 22, the lower floor alignment position signal 23, and the upper floor alignment position signal 24 are sent from the processing unit 15 to the control device. Other configurations are the same as those in the first embodiment.
　次に、動作について説明する。図８は、かご２が上昇しているときの図６の各位置センサ１７～２０のそれぞれの動作、ドア開閉可能信号２２、下側床合わせ位置信号２３及び上側床合わせ位置信号２４の時間的変化を示すタイミングチャートである。図に示すように、かご２が階床に下方から近づくと、まず、上部着床位置センサ１７及び上部床合わせ位置センサ１９の順にかご位置検出用プレート１３が検出領域に挿入され、上部着床位置センサ１７及び上部床合わせ位置センサ１９の順に検出動作が行われる。上部床合わせ位置センサ１９の検出動作が行われると、ドア開閉可能信号２２が処理部１５から制御装置へ出力される。これにより、ドア開閉可能区間にかご２があるとの判定が制御装置により行われる。 Next, the operation will be described. FIG. 8 shows the respective operations of the position sensors 17 to 20 in FIG. 6 when the car 2 is raised, the door opening / closing enable signal 22, the lower floor alignment position signal 23, and the upper floor alignment position signal 24 over time. It is a timing chart which shows change. As shown in the figure, when the car 2 approaches the floor from below, first, the car position detection plate 13 is inserted into the detection area in the order of the upper landing position sensor 17 and the upper floor alignment position sensor 19, and the upper landing is performed. The detection operation is performed in the order of the position sensor 17 and the upper floor alignment position sensor 19. When the detection operation of the upper floor alignment position sensor 19 is performed, a door open / close enable signal 22 is output from the processing unit 15 to the control device. Thus, the control device determines that the car 2 is in the door openable / closable section.
　この後、かご２がさらに上昇し、下部床合わせ位置センサ２０の検出領域にかご位置検出用プレート１３が挿入されると、下部床合わせ位置センサ２０の検出動作が行われる。これにより、ドア開閉可能信号２２の出力が維持されたまま、下側床合わせ位置信号２３が処理部１５から出力される。これにより、下側の床合わせ運転可能区間にかご２があるとの判定が制御装置により行われる。 Thereafter, when the car 2 further rises and the car position detection plate 13 is inserted into the detection area of the lower floor alignment position sensor 20, the detection operation of the lower floor alignment position sensor 20 is performed. Thereby, the lower floor alignment position signal 23 is output from the processing unit 15 while the output of the door open / close enable signal 22 is maintained. Accordingly, the control device determines that the car 2 is in the lower floor-to-floor operation enabled section.
　この後、かご２がさらに上昇し、下部着床位置センサ１８の検出領域にかご位置検出用プレート１３が挿入されると、下部着床位置センサ１８の検出動作が行われる。これにより、ドア開閉可能信号２２及び下側床合わせ位置信号２３のそれぞれの出力が維持されたまま、上側床合わせ位置信号２４が処理部１５から制御装置へ出力される。これにより、かご２がかご着床区間にあるとの判定が制御装置により行われる。かご２は、制御装置による巻上機の制御により、かご着床区間内に位置を合わせて階床に停止される。 Thereafter, when the car 2 further rises and the car position detection plate 13 is inserted into the detection area of the lower landing position sensor 18, the detection operation of the lower landing position sensor 18 is performed. Thus, the upper floor alignment position signal 24 is output from the processing unit 15 to the control device while the outputs of the door open / close enable signal 22 and the lower floor alignment position signal 23 are maintained. Thus, the control device determines that the car 2 is in the car landing section. The car 2 is stopped at the floor by matching the position in the car landing section under the control of the hoisting machine by the control device.
　この後、かご２が階床からさらに上昇すると、上部着床位置センサ１７、上部床合わせ位置センサ１９、下部床合わせ位置センサ２０及び下部着床位置センサ１８の順にかご位置検出用プレート１３の挿入が外れる。これにより、下側床合わせ位置信号２３、上側床合わせ位置信号２４及びドア開閉可能信号２２の順に処理部１５からの出力が停止される。 Thereafter, when the car 2 further rises from the floor, the car position detection plate 13 is inserted in the order of the upper landing position sensor 17, the upper floor alignment position sensor 19, the lower floor alignment position sensor 20, and the lower landing position sensor 18. Comes off. Accordingly, the output from the processing unit 15 is stopped in the order of the lower floor alignment position signal 23, the upper floor alignment position signal 24, and the door opening / closing enable signal 22.
　かご２が上側及び下側の床合わせ運転可能区間のいずれかにあるときの動作、及びかご２の位置がかご着床区間及び床合わせ運転可能区間のいずれからも外れているときの動作は、実施の形態１と同様である。 The operation when the car 2 is in one of the upper and lower floor-to-floor operable sections, and the operation when the position of the car 2 is out of either the car landing section or the floor-to-floor operable section, The same as in the first embodiment.
　このようなエレベータの位置検出装置では、各着床位置センサ１７，１８及び各床合わせ位置センサ１９，２０がかご２の移動方向に沿ってそれぞれ間隔を置いて配置されているので、昇降路１の水平断面に対する占有面積の縮小化を図ることができる。また、床合わせ運転可能区間からかご２の位置が外れることにより、各床合わせ位置センサ１９，２０のいずれかの検出動作が停止され、ドア開閉可能区間からかご２の位置が外れることにより、各床合わせ位置センサ１９，２０の検出動作がいずれも停止されるので、床合わせ運転可能区間をドア開閉可能区間とは別に設定することができる。従って、かご２の移動による故障の拡大を防止することができる。 In such an elevator position detection apparatus, the landing position sensors 17 and 18 and the floor alignment position sensors 19 and 20 are arranged at intervals along the moving direction of the car 2. The occupation area with respect to the horizontal cross section can be reduced. Further, when the position of the car 2 is deviated from the section where the floor-to-door operation is possible, the detection operation of any one of the floor- alignment position sensors 19 and 20 is stopped, and the position of the car 2 is deviated from the section where the door can be opened and closed. Since both the detection operations of the floor alignment position sensors 19 and 20 are stopped, the floor alignment operation possible section can be set separately from the door openable / closable section. Therefore, it is possible to prevent an increase in failure due to the movement of the car 2.
　また、各床合わせ位置センサ１９，２０は、磁気式のセンサであるので、例えば火災時の煙や外光等の外乱による誤動作の防止を図ることができる。これにより、かご２がドア開閉可能区間から外れた位置にあるときにドア駆動装置を誤って駆動させることを防止することができる。 Further, since each of the floor alignment position sensors 19 and 20 is a magnetic sensor, it is possible to prevent malfunction due to disturbance such as smoke or external light during a fire. Thereby, when the cage | basket | car 2 exists in the position which remove | deviated from the door opening / closing area | region, it can prevent driving a door drive device accidentally.
　なお、上記の例では、各床合わせ位置センサ１９，２０が磁気式のセンサとされているが、電磁式のセンサを各床合わせ位置センサ１９，２０としてもよい。 In the above example, the floor alignment position sensors 19 and 20 are magnetic sensors, but electromagnetic sensors may be used as the floor alignment position sensors 19 and 20.
　また、各上記実施の形態では、かご位置検出用プレート１３が昇降路１内に設けられ、検出器１４がかご２に設けられているが、かご位置検出用プレート１３をかご２に設け、検出器１４を昇降路１内に設けてもよい。 Further, in each of the above embodiments, the car position detection plate 13 is provided in the hoistway 1 and the detector 14 is provided in the car 2. However, the car position detection plate 13 is provided in the car 2 and is detected. A vessel 14 may be provided in the hoistway 1.
