実施の形態１．
　図１は、本実施の形態におけるエレベータードアの制御装置を説明するための構成図である。図１は、エレベーターのカゴ２０と乗場３０との間に形成された出入口周辺の垂直断面を示している。 Embodiment 1 FIG.
FIG. 1 is a configuration diagram for explaining an elevator door control device according to the present embodiment. FIG. 1 shows a vertical cross section around the doorway formed between the elevator car 20 and the landing 30.
　カゴ２０は、カゴドアパネル２１を備えている。カゴドアパネル２１の下端には、ガイドシュー２４が設けられている。ガイドシュー２４は、敷居に沿って水平方向にスライド可能である。カゴドアパネル２１の上方には、カゴドア開閉装置５０が設けられている。カゴドア開閉装置５０は、カゴドアハンガー２２、カゴローラ２３、カゴレール２５、モータプーリ２６、ドライブベルト２８及びドアモータ２７を備えている。カゴドアパネル２１の上端には、カゴドアハンガー２２が固定されている。カゴドアハンガー２２の上部には、カゴローラ２３が回転可能に設けられている。カゴドアパネル２１は、カゴドアハンガー２２及びカゴローラ２３を介してカゴレール２５に支持されている。カゴローラ２３は、カゴレール２５上を水平方向に移動可能である。カゴレール２５の上方には、モータプーリ２６が設けられている。モータプーリ２６は、ドアモータ２７の軸に取り付けられている。モータプーリ２６には、ドライブベルト２８が巻き掛けられている。ドライブベルト２８は、カゴドアハンガー２２と連結されている。 The cage 20 includes a cage door panel 21.

The cage door opening / closing device 50 includes a cage door hanger 22, a cage roller 23, a cage rail 25, a motor pulley 26, a drive belt 28, and a door motor 27. A basket door hanger 22 is fixed to the upper end of the basket door panel 21. A cage roller 23 is rotatably provided on the upper portion of the cage door hanger 22. The cage door panel 21 is supported by the cage rail 25 via a cage door hanger 22 and a cage roller 23. The cage roller 23 is movable in the horizontal direction on the cage rail 25. A motor pulley 26 is provided above the cage rail 25. The motor pulley 26 is attached to the shaft of the door motor 27. A drive belt 28 is wound around the motor pulley 26. The drive belt 28 is connected to the cage door hanger 22.
　乗場３０には、乗場ドアパネル３１が設けられている。乗場ドアパネル３１の下端には、ガイドシュー３４が設けられている。ガイドシュー３４は、敷居に沿って水平方向にスライド可能である。乗場ドアパネル３１の上端には、乗場ドアハンガー３２が固定されている。乗場ドアハンガー３２の上部には、乗場ドアローラ３３が回転可能に設けられている。乗場ドアパネル３１は、乗場ドアハンガー３２及び乗場ドアローラ３３を介して乗場レール３５に支持されている。乗場ドアローラ３３は、乗場レール３５上を水平方向に移動可能である。 The hall 30 is provided with a hall door panel 31. A guide shoe 34 is provided at the lower end of the landing door panel 31. The guide shoe 34 can slide in the horizontal direction along the threshold. A landing door hanger 32 is fixed to the upper end of the landing door panel 31. A landing door roller 33 is rotatably provided on the upper portion of the landing door hanger 32. The landing door panel 31 is supported by the landing rail 35 via a landing door hanger 32 and a landing door roller 33. The landing door roller 33 is movable on the landing rail 35 in the horizontal direction.
　カゴドアパネル２１と乗場ドアパネル３１との間には、連結装置３７が設けられている。連結装置３７は、カゴ２０が乗場３０の高さで停止すると、カゴドアパネル２１と乗場ドアパネル３１とを機械的に連結する。 A connecting device 37 is provided between the cage door panel 21 and the landing door panel 31. When the car 20 stops at the height of the landing 30, the connecting device 37 mechanically connects the car door panel 21 and the landing door panel 31.
　カゴ２０の上方には、ドアモータ２７を制御するドア制御装置３８が設けられている。ドア制御装置３８は、エレベーター全体を制御する制御盤３９と接続されている。制御盤３９は、カゴドアパネル２１及び乗場ドアパネル３１の状態に応じてエレベーターを制御する。また、カゴ２０の乗場３０側には、光電装置２９が設けられている。光電装置２９は、出入口における物体の有無を検出するためのセンサとして働く。 A door control device 38 for controlling the door motor 27 is provided above the cage 20. The door control device 38 is connected to a control panel 39 that controls the entire elevator. The control panel 39 controls the elevator according to the state of the cage door panel 21 and the landing door panel 31. A photoelectric device 29 is provided on the platform 30 side of the cage 20. The photoelectric device 29 functions as a sensor for detecting the presence or absence of an object at the entrance.
　図２は、図１に示すカゴドアパネル２１及びカゴドア開閉装置５０を乗場３０側から見た構成図である。以下、図１及び図２を参照して、エレベーターの出入口の開閉動作について説明する。 FIG. 2 is a configuration diagram of the cage door panel 21 and the cage door opening / closing device 50 shown in FIG. 1 as viewed from the landing 30 side. Hereinafter, the opening / closing operation of the entrance / exit of the elevator will be described with reference to FIGS. 1 and 2.
　ドアモータ２７が回転すると、モータプーリ２６が回転する。モータプーリ２６の回転により、ドライブベルト２８が移動する。ドライブベルト２８の移動により、カゴドアハンガー２２を介してカゴドアパネル２１が水平方向に移動する。カゴドアパネル２１の移動に伴って、連結装置３７によりカゴドアパネル２１と連結されている乗場ドアパネル３１も移動する。このようにして、カゴドアパネル２１及び乗場ドアパネル３１が移動することにより、エレベーターの出入口が開閉される。 When the door motor 27 rotates, the motor pulley 26 rotates. As the motor pulley 26 rotates, the drive belt 28 moves. By the movement of the drive belt 28, the cage door panel 21 moves in the horizontal direction via the cage door hanger 22. As the car door panel 21 moves, the landing door panel 31 connected to the car door panel 21 by the connecting device 37 also moves. Thus, when the cage door panel 21 and the landing door panel 31 move, the doorway of the elevator is opened and closed.
　また、図２に示すように、光電装置２９は、発光装置２９－１及び受光装置２９－２を備えている。受光装置２９－２は、カゴドアパネル２１に設けられている。カゴドアパネル２１において、受光装置２９－２が設けられている位置は、開閉動作における戸閉方向側の側端部付近である。なお、受光装置２９－２は、信号線によりドア制御装置３８と接続されている。また、カゴ２０は、受光装置２９－２と対向する位置に発光装置２９－１を備えている。このため、カゴドアパネル２１が開くことにより、発光装置２９－１及び受光装置２９－２は互いに離れる。一方、カゴドアパネル２１が閉まることにより、発光装置２９－１及び受光装置２９－２は互いに接近する。 As shown in FIG. 2, the photoelectric device 29 includes a light emitting device 29-1 and a light receiving device 29-2. The light receiving device 29-2 is provided on the cage door panel 21. In the cage door panel 21, the position where the light receiving device 29-2 is provided is near the side end portion on the door closing direction side in the opening / closing operation. The light receiving device 29-2 is connected to the door control device 38 by a signal line. Further, the basket 20 includes a light emitting device 29-1 at a position facing the light receiving device 29-2. Therefore, when the car door panel 21 is opened, the light emitting device 29-1 and the light receiving device 29-2 are separated from each other. On the other hand, when the cage door panel 21 is closed, the light emitting device 29-1 and the light receiving device 29-2 approach each other.
　図３は、本実施の形態における光電装置２９の構成図である。以下、図３を参照して、光電装置２９の構成を説明する。 FIG. 3 is a configuration diagram of the photoelectric device 29 in the present embodiment. Hereinafter, the configuration of the photoelectric device 29 will be described with reference to FIG.
　発光装置２９－１は、第１の発光手段３を備えている。また、発光装置２９－１は、第２の発光手段４を備えている。第２の発光手段４は、発光装置２９－１の上下方向における中間部及び下端部に設けられている。発光装置２９－１の中間部に設けられた第２の発光手段４と下端部に設けられた第２の発光手段４との間には、複数の第１の発光手段３が設けられている。発光装置２９－１の中間部に設けられた第２の発光手段４より上側にも、複数の第１の発光手段３が設けられている。 The light emitting device 29-1 includes the first light emitting means 3. Further, the light emitting device 29-1 includes the second light emitting means 4. The second light emitting means 4 is provided at an intermediate portion and a lower end portion in the vertical direction of the light emitting device 29-1. A plurality of first light emitting means 3 are provided between the second light emitting means 4 provided in the intermediate portion of the light emitting device 29-1 and the second light emitting means 4 provided in the lower end portion. . A plurality of first light emitting means 3 are also provided above the second light emitting means 4 provided in the intermediate portion of the light emitting device 29-1.
　受光装置２９－２は、第１の受光手段５を備えている。また、受光装置２９－２は、第２の受光手段６を備えている。第２の受光手段６は、受光装置２９－２の上下方向における中間部及び下端部に設けられている。受光装置２９－２の中間部に設けられた第２の受光手段６と下端部に設けられた第２の受光手段６との間には、複数の第１の受光手段５が設けられている。受光装置２９－２の中間部に設けられた第２の受光手段６より上側にも、複数の第１の受光手段５が設けられている。 The light receiving device 29-2 includes first light receiving means 5. The light receiving device 29-2 includes a second light receiving means 6. The second light receiving means 6 is provided at an intermediate portion and a lower end portion in the vertical direction of the light receiving device 29-2. A plurality of first light receiving means 5 are provided between the second light receiving means 6 provided at the intermediate portion of the light receiving device 29-2 and the second light receiving means 6 provided at the lower end. . A plurality of first light receiving means 5 are also provided above the second light receiving means 6 provided in the intermediate portion of the light receiving device 29-2.
　このように、第１の発光手段３及び第１の受光手段５は、同じ高さに配置されている。このため、第１の受光手段５は、第１の発光手段３と対向している。また、第２の発光手段４及び第２の受光手段６は、エレベーターの出入口の上下方向において同じ高さに配置されている。このため、第２の受光手段６は、第２の発光手段４と対向している。 Thus, the first light emitting means 3 and the first light receiving means 5 are arranged at the same height. Therefore, the first light receiving means 5 is opposed to the first light emitting means 3. Moreover, the 2nd light emission means 4 and the 2nd light reception means 6 are arrange | positioned at the same height in the up-down direction of the entrance / exit of an elevator. For this reason, the second light receiving means 6 faces the second light emitting means 4.
　なお、第１の受光手段５及び第２の受光手段６は、例えば、ビーム強度を判別する受光素子で形成される。また、カメラ等を第１の受光手段５及び第２の受光手段６として設けてもよい。この場合、撮影された画像の画素を区切り明度判別を行うことによってビーム強度を判別する機能を実現できる。 Note that the first light receiving means 5 and the second light receiving means 6 are formed of light receiving elements for determining the beam intensity, for example. A camera or the like may be provided as the first light receiving means 5 and the second light receiving means 6. In this case, it is possible to realize a function of discriminating the beam intensity by separating the pixels of the captured image and discriminating the brightness.
　以下、主に発光装置２９－１及び受光装置２９－２の動作について説明する。第１の発光手段３は、エレベーターの出入口を横切るようにビームを発射する。ビームを発射した第１の発光手段３と、それに対向する第１の受光手段５との間にビームを遮る物体が存在しない場合、第１の受光手段５は、ビームを受光する。第１の発光手段３により発射されたビームを遮る物体とは、例えば、エレベーターの乗客である。第１の受光手段５は、第１の発光手段３から発射されたビームを受光しなかった場合は、検出信号を出力する。一方、第１の発光手段３から発射されたビームを受光した場合、第１の受光手段５は、検出信号を出力しない。 Hereinafter, operations of the light emitting device 29-1 and the light receiving device 29-2 will be mainly described. The first light emitting means 3 emits a beam so as to cross the entrance / exit of the elevator. When there is no object that blocks the beam between the first light emitting unit 3 that has emitted the beam and the first light receiving unit 5 that faces the first light emitting unit 3, the first light receiving unit 5 receives the beam. The object that blocks the beam emitted by the first light emitting means 3 is, for example, an elevator passenger. The first light receiving means 5 outputs a detection signal when the beam emitted from the first light emitting means 3 is not received. On the other hand, when the beam emitted from the first light emitting means 3 is received, the first light receiving means 5 does not output a detection signal.
　第２の発光手段４は、エレベーターの出入口を横切るようにビームを発射する。第２の発光手段４から発射されるビームは、第１の発光手段３から発射されるビームよりも径が小さい。ビームを発射した第２の発光手段４と、それに対向する第２の受光手段６との間にビームを遮る物体が存在しない場合、第２の受光手段６は、ビームを受光する。第２の発光手段４により発射されたビームを遮る物体とは、例えば、細い紐状物体である。第２の受光手段６は、第２の発光手段４から発射されたビームを受光しなかった場合は、検出信号を出力する。一方、第２の発光手段４から発射されたビームを受光した場合、第２の受光手段６は、検出信号を出力しない。 The second light emitting means 4 emits a beam so as to cross the entrance / exit of the elevator. The beam emitted from the second light emitting means 4 has a smaller diameter than the beam emitted from the first light emitting means 3. When there is no object that blocks the beam between the second light emitting unit 4 that has emitted the beam and the second light receiving unit 6 facing the second light emitting unit 4, the second light receiving unit 6 receives the beam. The object that blocks the beam emitted by the second light emitting means 4 is, for example, a thin string-like object. The second light receiving means 6 outputs a detection signal when the beam emitted from the second light emitting means 4 is not received. On the other hand, when the beam emitted from the second light emitting means 4 is received, the second light receiving means 6 does not output a detection signal.
　なお、第１の受光手段５及び第２の受光手段６は、有効な状態と無効な状態とを切り替え可能である。第１の受光手段５及び第２の受光手段６は、有効な状態のときに上述した動作を行う。一方、第１の受光手段５及び第２の受光手段６は、無効な状態のときには、ビームを受光したか否かにかかわらず検出信号を出力しない。 Note that the first light receiving means 5 and the second light receiving means 6 can be switched between an effective state and an invalid state. The first light receiving means 5 and the second light receiving means 6 perform the above-described operation when in an effective state. On the other hand, when the first light receiving unit 5 and the second light receiving unit 6 are in an invalid state, they do not output a detection signal regardless of whether or not the beam is received.
　受光装置２９－２は、第１の受光手段５の出力及び第２の受光手段６の出力に基づいてＯＲ演算を行う。受光装置２９－２は、ＯＲ演算の結果に基づいて出力された信号をドア制御装置３８に送信する。ドア制御装置３８は、受光装置２９－２から受信した信号に基づいて、出入口において物体が検出されたか否かを判定する。 The light receiving device 29-2 performs an OR operation based on the output of the first light receiving means 5 and the output of the second light receiving means 6. The light receiving device 29-2 transmits a signal output based on the result of the OR operation to the door control device 38. The door control device 38 determines whether an object is detected at the entrance based on the signal received from the light receiving device 29-2.
　図４は、本実施の形態におけるエレベーターの出入口における物体の有無を検出する方法を示すフローチャートである。以下、図４を参照して、エレベーターの出入口における物体の有無を検出する方法を説明する。 FIG. 4 is a flowchart showing a method for detecting the presence or absence of an object at the entrance of the elevator in the present embodiment. Hereinafter, a method for detecting the presence / absence of an object at an entrance / exit of an elevator will be described with reference to FIG.
　受光装置２９－２は、第１の受光手段５が検出信号を出力したか否かの判定を行う（ステップＳ１０１）。ステップＳ１０１で、第１の受光手段５が検出信号を出力したと判定された場合、受光装置２９－２は、物体が検出されたことを示す信号をドア制御装置３８に送信する。この場合、ドア制御装置３８は、エレベーターの出入口において物体が検出されたと判定する（ステップＳ１０２）。ステップＳ１０２の後は、ステップＳ１０１に戻る。 The light receiving device 29-2 determines whether or not the first light receiving means 5 has output a detection signal (step S101). If it is determined in step S101 that the first light receiving means 5 has output a detection signal, the light receiving device 29-2 transmits a signal indicating that an object has been detected to the door control device 38. In this case, the door control device 38 determines that an object has been detected at the entrance / exit of the elevator (step S102). After step S102, the process returns to step S101.
　ステップＳ１０１で、第１の受光手段５が検出信号を出力しなかったと判定された場合、受光装置２９－２は、第２の受光手段６が検出信号を出力したか否かの判定を行う（ステップＳ１０３）。ステップＳ１０３で、第２の受光手段６が検出信号を出力したと判定された場合、ステップＳ１０２に進む。 If it is determined in step S101 that the first light receiving means 5 has not output the detection signal, the light receiving device 29-2 determines whether or not the second light receiving means 6 has output the detection signal ( Step S103). If it is determined in step S103 that the second light receiving means 6 has output a detection signal, the process proceeds to step S102.
　ステップＳ１０３で、第２の受光手段６が検出信号を出力しなかったと判定された場合、受光装置２９－２は、物体が検出されなかったことを示す信号をドア制御装置３８に送信する。この場合、ドア制御装置３８は、エレベーターの出入口において物体が検出されていないと判定する（ステップＳ１０４）。ステップＳ１０４の後は、ステップＳ１０１に戻る。 If it is determined in step S103 that the second light receiving means 6 has not output a detection signal, the light receiving device 29-2 transmits a signal indicating that no object has been detected to the door control device 38. In this case, the door control device 38 determines that no object is detected at the entrance of the elevator (step S104). After step S104, the process returns to step S101.
　図５は、本実施の形態における第１の受光手段５及び第２の受光手段６の状態の変化を示す概念図である。以下、図５を参照して、第１の受光手段５が有効となる期間及び第２の受光手段６が有効となる期間について説明する。 FIG. 5 is a conceptual diagram showing changes in the states of the first light receiving means 5 and the second light receiving means 6 in the present embodiment. Hereinafter, a period in which the first light receiving unit 5 is effective and a period in which the second light receiving unit 6 is effective will be described with reference to FIG.
　図５の横軸は、カゴドアパネル２１の位置を示している。戸閉動作中は、横軸の右から左へカゴドアパネル２１の位置が変化する。なお、横軸の「全閉」より左側は、カゴドアパネル２１全閉後にカゴ２０が走行している状態を示している。第１の受光手段５は、カゴドアパネル２１が全開の位置から全閉近くの位置まで移動する間は有効となっている。一方、第１の受光手段５は、カゴドアパネル２１が全閉の状態及びカゴ２０が走行している状態では無効となっている。全開から全閉近くまでの範囲を、第１の受光手段５の有効範囲Ｒ１と呼ぶ。第２の受光手段６は、戸閉動作の途中からカゴ２０の走行の途中までの間は有効となっている。一方、第２の受光手段６は、カゴドアパネル２１が全開の位置から戸閉動作の途中の位置まで移動する間は無効となっている。戸閉動作の途中からカゴ２０の走行の途中までの範囲を、第２の受光手段６の有効範囲Ｒ２と呼ぶ。このため、Ｒ１とＲ２とが重複している範囲では、第１の受光手段５と第２の受光手段６とが同時に有効となっている。第１の受光手段５と第２の受光手段６とが同時に有効な期間をＴａと呼ぶ。また、Ｒ２のうちＲ１と重複していない範囲では、カゴドアパネル２１全閉後に第２の受光手段６が有効となっている。カゴドアパネル２１全閉後に第２の受光手段６が有効な期間をＴｂと呼ぶ。 The horizontal axis in FIG. 5 indicates the position of the cage door panel 21. During the door closing operation, the position of the cage door panel 21 changes from right to left on the horizontal axis. Note that the left side of the horizontal axis “fully closed” indicates a state in which the car 20 is traveling after the car door panel 21 is fully closed. The first light receiving means 5 is effective while the cage door panel 21 moves from the fully open position to a position near the fully closed position. On the other hand, the first light receiving means 5 is invalid when the cage door panel 21 is fully closed and the cage 20 is traveling. A range from fully open to close to full close is referred to as an effective range R1 of the first light receiving means 5. The second light receiving means 6 is effective from the middle of the door closing operation to the middle of the traveling of the basket 20. On the other hand, the second light receiving means 6 is disabled while the cage door panel 21 moves from the fully opened position to a position in the middle of the door closing operation. A range from the middle of the door closing operation to the middle of the traveling of the car 20 is referred to as an effective range R2 of the second light receiving means 6. For this reason, in the range where R1 and R2 overlap, the first light receiving means 5 and the second light receiving means 6 are simultaneously effective. A period in which the first light receiving means 5 and the second light receiving means 6 are simultaneously effective is referred to as Ta. Further, in the range of R2 that does not overlap with R1, the second light receiving means 6 is effective after the cage door panel 21 is fully closed. A period in which the second light receiving means 6 is effective after the cage door panel 21 is fully closed is referred to as Tb.
　図５に示す第１の受光手段５と第２の受光手段６とが同時に有効な期間Ｔａは、カゴドアパネル２１の戸閉動作により発光装置２９－１と受光装置２９－２とが互いに接近する期間である。このため、期間Ｔａは、例えば、カゴドアパネル２１が全開の位置から戸閉方向に予め設定された距離移動したときに開始するように設定される。また、期間Ｔａは、カゴドアパネル２１が全開の位置から戸閉方向に予め設定された時間移動したときに開始するように設定されてもよい。一方、カゴドアパネル２１全閉後に第２の受光手段６が有効な期間Ｔｂは、カゴ２０が予め設定された距離走行したときに終了するように設定される。 In the period Ta in which the first light receiving means 5 and the second light receiving means 6 are simultaneously effective as shown in FIG. 5, the light emitting device 29-1 and the light receiving device 29-2 approach each other by the door closing operation of the cage door panel 21. It is a period. For this reason, the period Ta is set so as to start, for example, when the cage door panel 21 moves from the fully opened position by a predetermined distance in the door closing direction. The period Ta may be set to start when the cage door panel 21 moves from the fully open position in the door closing direction for a preset time. On the other hand, the period Tb in which the second light receiving means 6 is effective after the car door panel 21 is fully closed is set to end when the car 20 travels a preset distance.
　図６は、カゴドアパネル２１の上下方向における中間部が乗場３０の床付近となるまでカゴ２０が下降した状態を示す構成図である。図７は、カゴドアパネル２１の下端部が出入口の上端付近となるまでカゴ２０が上昇した状態を示す構成図である。以下、図６及び図７を参照して、カゴドアパネル２１全閉後に第２の受光手段６が有効な期間Ｔｂの設定について説明する。 FIG. 6 is a configuration diagram showing a state in which the cage 20 is lowered until an intermediate portion in the vertical direction of the cage door panel 21 is near the floor of the hall 30. FIG. 7 is a configuration diagram showing a state where the cage 20 is raised until the lower end portion of the cage door panel 21 is near the upper end of the entrance / exit. Hereinafter, the setting of the period Tb in which the second light receiving means 6 is effective after the cage door panel 21 is fully closed will be described with reference to FIGS.
　図６及び図７は、カゴドアパネル２１により紐状物体９１が挟まれた状態でカゴ２０が走行開始した状況を示している。紐状物体９１とは、例えば、ペットのリード等である。このような紐状物体９１は、カゴドアパネル２１の中間部より下側で挟まれることが多い。このため、図６に示すように、カゴ２０が下降した場合、紐状物体９１は、光電装置２９の上下方向における中間部を通過する。また、図７に示すように、カゴ２０が上昇した場合、紐状物体９１は、光電装置２９の下端部を通過する。その結果、第２の受光手段６へのビームが遮られることにより、紐状物体９１が検出される。このため、期間Ｔｂは、カゴ２０が下降する場合は、カゴ２０が図６に示す位置に下降するまで継続するように設定される。つまり、第２の受光手段６は、カゴ２０の下降によりカゴドアパネル２１の上下方向における中間部が乗場３０の床付近となるまでは有効となっている。そして、第２の受光手段６は、カゴドアパネル２１の上下方向における中間部が乗場３０の床付近となるまでカゴ２０が下降した後は無効となる。また、期間Ｔｂは、カゴ２０が上昇する場合は、カゴ２０が図７に示す位置に上昇するまで継続するように設定される。つまり、第２の受光手段６は、カゴ２０の上昇によりカゴドアパネル２１の下端部が出入口の上端付近となるまでは有効となっている。そして、第２の受光手段６は、カゴドアパネル２１の下端部が出入口の上端付近となるまでカゴ２０が上昇した後は無効となる。 6 and 7 show a situation in which the cage 20 has started running with the string-like object 91 sandwiched between the cage door panels 21. FIG. The string-like object 91 is, for example, a pet lead. Such a string-like object 91 is often sandwiched below the intermediate portion of the cage door panel 21. For this reason, as shown in FIG. 6, when the cage 20 is lowered, the string-like object 91 passes through an intermediate portion in the vertical direction of the photoelectric device 29. Also, as shown in FIG. 7, when the cage 20 is raised, the string-like object 91 passes through the lower end portion of the photoelectric device 29. As a result, the string-like object 91 is detected by blocking the beam to the second light receiving means 6. Therefore, the period Tb is set to continue until the cage 20 descends to the position shown in FIG. 6 when the cage 20 descends. That is, the second light receiving means 6 is effective until the intermediate portion in the vertical direction of the cage door panel 21 is near the floor of the landing 30 due to the lowering of the cage 20. And the 2nd light-receiving means 6 becomes invalid after the cage | basket 20 descend | falls until the intermediate part in the up-down direction of the cage door panel 21 becomes the floor vicinity of the landing 30. Further, the period Tb is set to continue until the cage 20 rises to the position shown in FIG. 7 when the cage 20 rises. That is, the second light receiving means 6 is effective until the lower end portion of the cage door panel 21 comes close to the upper end of the doorway due to the raising of the cage 20. And the 2nd light-receiving means 6 becomes invalid after the cage | basket 20 raises until the lower end part of the cage door panel 21 becomes near the upper end of an entrance / exit.
　上述したとおり、本実施の形態では、光電装置２９は、第１の発光手段３及び第１の受光手段５を備えている。また、光電装置２９は、第２の発光手段４及び第２の受光手段６を備えている。第２の発光手段４は、第１の発光手段３から発射されるビームよりも径が小さいビームを発射する。このため、第２の受光手段６の出力に基づく物体の検出感度は、第１の受光手段５の出力に基づく物体の検出感度よりも高い。これにより、同一筐体の中に感度の異なる２種類のセンサを設けることができる。その結果、省スペース化及びコストダウンを図りつつ、エレベーターの出入口において乗客及び紐状物体等を検出可能なエレベータードアの制御装置を実現できる。 As described above, in this embodiment, the photoelectric device 29 includes the first light emitting means 3 and the first light receiving means 5. Further, the photoelectric device 29 includes a second light emitting unit 4 and a second light receiving unit 6. The second light emitting means 4 emits a beam having a smaller diameter than the beam emitted from the first light emitting means 3. For this reason, the detection sensitivity of the object based on the output of the second light receiving means 6 is higher than the detection sensitivity of the object based on the output of the first light receiving means 5. Thereby, two types of sensors having different sensitivities can be provided in the same housing. As a result, it is possible to realize an elevator door control device capable of detecting passengers, string-like objects, and the like at the entrance and exit of the elevator while saving space and reducing costs.
　上述したとおり、本実施の形態では、第２の発光手段４及び第２の受光手段６は、光電装置２９の上下方向における中間部及び下端部に設けられている。これにより、カゴドアパネル２１により挟まれた状態で垂れ下がる可能性の高い紐状物体の検出確率を向上できる。また、カゴドアパネル２１により挟まれた状態で、カゴ２０の昇降とともに上下方向に動く紐状物体を検出することができる。さらに、第２の発光手段４及び第２の受光手段６を光電装置２９の一部の箇所に限定して設けているため、光電装置２９の価格を抑えることができる。 As described above, in the present embodiment, the second light emitting means 4 and the second light receiving means 6 are provided at the middle and lower end portions in the vertical direction of the photoelectric device 29. Thereby, the detection probability of the string-like object that is highly likely to hang down while being sandwiched between the cage door panels 21 can be improved. Further, it is possible to detect a string-like object that moves up and down as the cage 20 moves up and down while being sandwiched between the cage door panels 21. Furthermore, since the second light emitting means 4 and the second light receiving means 6 are provided only in a part of the photoelectric device 29, the price of the photoelectric device 29 can be reduced.
　上述したとおり、本実施の形態では、受光装置２９－２は、第１の受光手段５の出力及び第２の受光手段６の出力に基づいてＯＲ演算を行う。受光装置２９－２は、ＯＲ演算の結果に基づいて出力された信号をドア制御装置３８に送信する。ドア制御装置３８は、受光装置２９－２から受信した信号に基づいて、出入口において物体が検出されたか否かを判定する。このため、受光装置２９－２からドア制御装置３８に信号を送信するための信号線を２本設ける必要がない。その結果、配線を少なくすることができる。 As described above, in the present embodiment, the light receiving device 29-2 performs an OR operation based on the output of the first light receiving means 5 and the output of the second light receiving means 6. The light receiving device 29-2 transmits a signal output based on the result of the OR operation to the door control device 38. The door control device 38 determines whether an object is detected at the entrance based on the signal received from the light receiving device 29-2. For this reason, it is not necessary to provide two signal lines for transmitting signals from the light receiving device 29-2 to the door control device 38. As a result, wiring can be reduced.
　上述したとおり、本実施の形態では、第１の受光手段５と第２の受光手段６とが同時に有効な期間Ｔａが存在する。期間Ｔａの間は、２種類の受光手段を有効にすることで、エレベーターの出入口における乗客及び紐状物体等の検出確率を向上させることができる。 As described above, in the present embodiment, there is a period Ta in which the first light receiving means 5 and the second light receiving means 6 are effective at the same time. During the period Ta, by enabling two types of light receiving means, it is possible to improve the detection probability of passengers and string-like objects at the entrance of the elevator.
　上述したとおり、本実施の形態では、第１の受光手段５と第２の受光手段６とが同時に有効な期間Ｔａは、カゴドアパネル２１の戸閉動作により発光装置２９－１と受光装置２９－２とが互いに接近する期間である。この期間には、エレベーターの出入口の通行可能な部分が狭くなっているため、カゴドアパネル２１により物体が挟まれる事故が発生しやすい。このため、２種類の受光手段を有効にすることで乗客及び紐状物体等の検出確率を向上させ、事故の発生を防止することができる。また、第２の受光手段６の出力に基づいた検出感度が高いため、第２の受光手段６が有効なときは、埃等の誤検出によりカゴドアパネル２１が閉まらなくなる可能性がある。カゴドアパネル２１により紐状物体が挟まれた状態でカゴ２０が走行することを防止するためには、戸閉動作により発光装置２９－１と受光装置２９－２とが互いに接近してから第２の受光手段６を有効にすればよい。このため、カゴドアパネル２１が全開に近いときは第２の受光手段６を無効にすることで、エレベーターの運行効率を高めることができる。 As described above, in the present embodiment, during the period Ta in which the first light receiving means 5 and the second light receiving means 6 are simultaneously effective, the light emitting device 29-1 and the light receiving device 29- 2 is a period in which 2 approaches each other. During this period, an accessible portion of the elevator entrance is narrow, and an accident in which an object is pinched by the cage door panel 21 is likely to occur. For this reason, the detection probability of a passenger, a string-like object, etc. can be improved by enabling two types of light receiving means, and the occurrence of an accident can be prevented. In addition, since the detection sensitivity based on the output of the second light receiving means 6 is high, the cage door panel 21 may not be closed due to erroneous detection of dust or the like when the second light receiving means 6 is effective. In order to prevent the cage 20 from running while the string-like object is sandwiched between the cage door panels 21, the second light emitting device 29-1 and the light receiving device 29-2 approach each other by the door closing operation. The light receiving means 6 may be made effective. For this reason, when the cage door panel 21 is almost fully open, the operation efficiency of the elevator can be improved by disabling the second light receiving means 6.
　上述したとおり、本実施の形態では、カゴドアパネル２１全閉後に第２の受光手段６が有効な期間Ｔｂが存在する。カゴドアパネル２１により紐状物体が挟まれた状態でカゴ２０が走行すると、紐状物体は上下に移動する可能性が高い。紐状物体は、上下に移動することで、第２の発光手段４と第２の受光手段６との間を通過する。このため、カゴドアパネル２１全閉後に第２の受光手段６を有効にすることで、カゴドアパネル２１により紐状物体が挟まれた状態でカゴ２０が走行開始した場合であっても、紐状物体を検出することができる。カゴ２０の走行中に紐状物体が検出された場合は、例えば、カゴ２０の走行を停止させる等の動作が可能となる。 As described above, in the present embodiment, there is a period Tb in which the second light receiving means 6 is effective after the cage door panel 21 is fully closed. When the cage 20 travels with the string-like object sandwiched between the cage door panels 21, the string-like object is likely to move up and down. The string-like object passes between the second light emitting means 4 and the second light receiving means 6 by moving up and down. For this reason, even if it is a case where the cage | basket 20 starts a driving | running | working in the state where the string-like object was pinched | interposed by the cage door panel 21 by enabling the 2nd light receiving means 6 after the cage door panel 21 fully closed Can be detected. When a string-like object is detected while the car 20 is traveling, for example, an operation such as stopping the car 20 can be performed.
　上述したとおり、本実施の形態では、カゴドアパネル２１全閉後に第２の受光手段６が有効な期間Ｔｂは、カゴ２０が下降する場合は、カゴ２０が図６に示す位置に下降するまで継続するように設定される。また、期間Ｔｂは、カゴ２０が上昇する場合は、カゴ２０が図７に示す位置に上昇するまで継続するように設定される。カゴドアパネル２１により紐状物体が挟まれた状態でカゴ２０が走行開始した場合、カゴ２０が図６に示す位置まで下降すれば、紐状物体はカゴドアパネル２１の上下方向における中間部を通過する。また、カゴ２０が図７に示す位置まで上昇すれば、紐状物体は光電装置２９の下端部を通過する。このため、カゴ２０が下降する場合、第２の受光手段６がカゴドアパネル２１の上下方向における中間部が乗場３０の床付近となるまで有効であれば、紐状物体を検出することができる。また、カゴ２０が上昇する場合、第２の受光手段６は、カゴドアパネル２１の下端部が出入口の上端付近となるまで有効であれば、紐状物体を検出することができる。なお、上述した位置よりも先まで走行したカゴ２０は速度が高くなっているため、停止させない方がよい。このため、第２の受光手段６が有効な期間は、上述したように設定されるのが望ましい。 As described above, in the present embodiment, the period Tb in which the second light receiving means 6 is effective after the cage door panel 21 is fully closed continues until the cage 20 descends to the position shown in FIG. 6 when the cage 20 descends. Set to do. Further, the period Tb is set to continue until the cage 20 rises to the position shown in FIG. 7 when the cage 20 rises. When the cage 20 starts running with the string-like object sandwiched between the cage door panels 21, if the cage 20 descends to the position shown in FIG. 6, the string-like object passes through the intermediate portion in the vertical direction of the cage door panel 21. . If the cage 20 is raised to the position shown in FIG. 7, the string-like object passes through the lower end portion of the photoelectric device 29. For this reason, when the cage 20 is lowered, the string-like object can be detected if the second light receiving means 6 is effective until the intermediate portion in the vertical direction of the cage door panel 21 is near the floor of the landing 30. When the cage 20 is raised, the second light receiving means 6 can detect a string-like object if it is effective until the lower end of the cage door panel 21 is near the upper end of the entrance / exit. In addition, it is better not to stop the car 20 that has traveled beyond the position described above because the speed is high. For this reason, it is desirable to set the period during which the second light receiving means 6 is effective as described above.
　なお、本実施の形態では、図３に示すように、受光装置２９－２がカゴドアパネル２１に設けられている。しかし、図８に示すように、発光装置２９－１をカゴドアパネル２１に設けることとしてもよい。本構成によれば、第１の受光手段５及び第２の受光手段６がカゴドアパネル２１とともに移動することがない。このため、移動する際の揺れ等による第１の受光手段５及び第２の受光手段６の誤作動及び受光精度の低下を防止することができる。 In the present embodiment, as shown in FIG. 3, the light receiving device 29-2 is provided on the cage door panel 21. However, as shown in FIG. 8, the light emitting device 29-1 may be provided on the cage door panel 21. According to this configuration, the first light receiving means 5 and the second light receiving means 6 do not move together with the car door panel 21. For this reason, it is possible to prevent malfunctions of the first light receiving means 5 and the second light receiving means 6 and a decrease in light receiving accuracy due to shaking or the like when moving.
実施の形態２．
　図９は、本実施の形態における光電装置２９の構成図である。本実施の形態は、光電装置２９の構成を除いて実施の形態１と同様である。以下、実施の形態１との相違点について説明する。 Embodiment 2. FIG.
FIG. 9 is a configuration diagram of the photoelectric device 29 in the present embodiment. The present embodiment is the same as the first embodiment except for the configuration of the photoelectric device 29. Hereinafter, differences from the first embodiment will be described.
　本実施の形態において、第２の発光手段４は、第１の発光手段３と同じものである。つまり、第１の受光手段５及び第２の受光手段６は、同じ径のビームを受光する。ただし、本実施の形態における第２の受光手段６は、第１の受光手段５よりも高い分解能でビームを受光する。 In the present embodiment, the second light emitting means 4 is the same as the first light emitting means 3. That is, the first light receiving means 5 and the second light receiving means 6 receive beams having the same diameter. However, the second light receiving means 6 in the present embodiment receives the beam with higher resolution than the first light receiving means 5.
　このような構成によれば、第２の受光手段６の出力に基づく物体の検出感度は、第１の受光手段５の出力に基づく物体の検出感度よりも高くなる。これにより、１種類の発光手段を用いて、同一筐体の中に感度の異なる２種類のセンサを設けることができる。その結果、省スペース化及びコストダウンを図りつつ、エレベーターの出入口において乗客及び紐状物体等を検出可能なエレベータードアの制御装置を実現できる。 According to such a configuration, the detection sensitivity of the object based on the output of the second light receiving means 6 is higher than the detection sensitivity of the object based on the output of the first light receiving means 5. Accordingly, two types of sensors having different sensitivities can be provided in the same housing by using one type of light emitting means. As a result, it is possible to realize an elevator door control device capable of detecting passengers, string-like objects, and the like at the entrance and exit of the elevator while saving space and reducing costs.
　なお、本実施の形態では、図９に示すように、受光装置２９－２がカゴドアパネル２１に設けられている。しかし、図１０に示すように、発光装置２９－１をカゴドアパネル２１に設けることとしてもよい。本構成によれば、第１の受光手段５及び第２の受光手段６がカゴドアパネル２１とともに移動することがない。このため、移動する際の揺れ等による第１の受光手段５及び第２の受光手段６の誤作動を防止することができる。 In the present embodiment, as shown in FIG. 9, the light receiving device 29-2 is provided on the cage door panel 21. However, as shown in FIG. 10, the light emitting device 29-1 may be provided on the cage door panel 21. According to this configuration, the first light receiving means 5 and the second light receiving means 6 do not move together with the car door panel 21. For this reason, it is possible to prevent the first light receiving means 5 and the second light receiving means 6 from malfunctioning due to shaking during movement.
　上述したとおり、実施の形態１及び２において、第１の受光手段５及び第２の受光手段６は、ビームを受光しなかった場合に検出信号を出力する。また、第１の受光手段５及び第２の受光手段６は、ビームを受光した場合に検出信号を出力しない。しかし、ビームを受光した場合に検出信号を出力し、ビームを受光しなかった場合に検出信号を出力しないこととしてもよい。 As described above, in the first and second embodiments, the first light receiving unit 5 and the second light receiving unit 6 output a detection signal when the beam is not received. The first light receiving means 5 and the second light receiving means 6 do not output a detection signal when receiving a beam. However, the detection signal may be output when the beam is received, and the detection signal may not be output when the beam is not received.
　上述したとおり、実施の形態１及び２において、第１の受光手段５及び第２の受光手段６は、ビームを受光しなかった場合に検出信号を出力する。また、第１の受光手段５及び第２の受光手段６は、ビームを受光した場合に検出信号を出力しない。しかし、第１の受光手段５及び第２の受光手段６が、ビームを受光した場合に検出信号とは異なる信号を出力することとしてもよい。 As described above, in the first and second embodiments, the first light receiving unit 5 and the second light receiving unit 6 output a detection signal when the beam is not received. The first light receiving means 5 and the second light receiving means 6 do not output a detection signal when receiving a beam. However, the first light receiving means 5 and the second light receiving means 6 may output a signal different from the detection signal when receiving the beam.
　上述したとおり、実施の形態１及び２において、第１の受光手段５及び第２の受光手段６は、無効な状態のときには検出信号を出力しない。しかし、第１の受光手段５及び第２の受光手段６は検出信号を出力するが、受光装置２９－２は検出信号に基づいた信号の出力を行わないこととしても同様の効果を得られる。また、受光装置２９－２は検出信号に基づいた信号の出力を行うが、ドア制御装置３８は受光装置２９－２から受信した信号に基づいた判定を行わないこととしてもよい。 As described above, in the first and second embodiments, the first light receiving means 5 and the second light receiving means 6 do not output detection signals when in an invalid state. However, although the first light receiving means 5 and the second light receiving means 6 output detection signals, the light receiving device 29-2 can obtain the same effect even if it does not output signals based on the detection signals. Further, although the light receiving device 29-2 outputs a signal based on the detection signal, the door control device 38 may not perform the determination based on the signal received from the light receiving device 29-2.
　上述したとおり、実施の形態１及び２では、カゴ２０に光電装置２９が設けられている。しかし、乗場３０側に光電装置２９を設けることとしても、エレベーターの出入口において物体の有無を検出することは可能である。ただし、その場合は、建物の各階に光電装置２９を設ける必要がある。このため、省スペース化及びコストダウンを図るには、カゴ２０に光電装置２９を設ける方がよい。 As described above, in the first and second embodiments, the photoelectric device 29 is provided in the basket 20. However, even if the photoelectric device 29 is provided on the landing 30 side, it is possible to detect the presence or absence of an object at the entrance of the elevator. However, in that case, it is necessary to provide the photoelectric device 29 on each floor of the building. For this reason, in order to save space and reduce costs, it is better to provide the photoelectric device 29 in the basket 20.
　上述したとおり、実施の形態１及び２では、片開き方式のドアを備えたエレベーターについて説明している。しかし、本発明は、両開き方式のドアを備えたエレベーターにも適用できる。その場合は、一方のカゴドアパネルに発光装置２９－１を設け、他方のカゴドアパネルに受光装置２９－２を設ければよい。 As described above, in the first and second embodiments, an elevator having a single-open door is described. However, the present invention can also be applied to an elevator having a double door. In that case, the light emitting device 29-1 may be provided on one of the car door panels, and the light receiving device 29-2 may be provided on the other car door panel.
　以上のように、本発明に係るエレベータードアの制御装置は、出入口における物体の有無を検出するエレベーターに利用できる。 As described above, the elevator door control device according to the present invention can be used for an elevator that detects the presence or absence of an object at an entrance.
