Description
本発明は、乗客コンベア用の移動手摺装置に関する。
The present invention relates to a mobile handrail device for a passenger conveyor.
日本特開２００７－１７６６７１号公報には、移動手摺を備える乗客コンベアが記載されている。この乗客コンベアの移動手摺の手摺ベルトは、乗客コンベアの走行モータの出力軸に連結された駆動シーブによって、乗客コンベアのステップと同じ速さで循環走行するように構成されている。この駆動シーブの近傍には、手摺ベルトを下側から支持する案内ローラが設置されている。更に、この案内ローラには回転数を検出する回転数検出装置が設置され、検出された案内ローラの回転数に基づいて手摺ベルトの移動速度が検出される。
Japanese Patent Application Laid-Open No. 2007-176671 describes a passenger conveyor provided with a moving handrail. The handrail belt of the moving handrail of the passenger conveyor is configured to circulate at the same speed as the steps of the passenger conveyor by a drive sheave connected to the output shaft of the traveling motor of the passenger conveyor. A guide roller that supports the handrail belt from below is installed in the vicinity of the drive sheave. Further, a rotation speed detecting device for detecting the rotation speed is installed in the guide roller, and the moving speed of the handrail belt is detected based on the detected rotation speed of the guide roller.
ローラの回転数を回転数検出装置により検出することで手摺ベルトの移動速度を算出する場合、回転数検出装置に関する専用部品の設置が不可欠であり、その設置はある程度複雑なものとなる。このため乗客コンベアの保全性により高い配慮が必要となる。更に、部品点数が増加するため乗客コンベアのレイアウトへの配慮が必要となる。
When calculating the moving speed of the handrail belt by detecting the rotation speed of the roller with the rotation speed detection device, it is indispensable to install the dedicated parts related to the rotation speed detection device, and the installation becomes complicated to some extent. Therefore, higher consideration is required for the maintainability of the passenger conveyor. Furthermore, since the number of parts increases, it is necessary to consider the layout of the passenger conveyor.
また案内ローラの磨耗、すべり、及び、浮き上がり等によってローラの回転数と手摺ベルトの移動速度との間にずれが生じる場合がある。この場合、ローラの回転数に基づいて算出される手摺ベルトの移動速度にも検出誤差が生じることとなる。手摺ベルトの移動速度の検出誤差は乗客コンベアの誤作動を生じさせる虞がある。
In addition, there may be a discrepancy between the rotation speed of the roller and the moving speed of the handrail belt due to wear, slippage, and lifting of the guide roller. In this case, a detection error also occurs in the moving speed of the handrail belt calculated based on the rotation speed of the roller. A detection error of the moving speed of the handrail belt may cause a malfunction of the passenger conveyor.
本発明は、上述の課題を解決するためになされたもので、手摺ベルトの移動速度をより高い精度で検出することができる簡素化された乗客コンベア用の移動手摺装置を提供することを目的とするものである。
The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a simplified moving handrail device for a passenger conveyor capable of detecting the moving speed of a handrail belt with higher accuracy. Is what you do.
本発明の乗客コンベア用の移動手摺装置は、無端状に形成された手摺ベルトと、誘導型近接センサと、制御部と、を備える。手摺ベルトは、内面側に、手摺ベルトの移動方向に沿って無端状に配置された帆布部を備える。帆布部には、移動方向に沿って一定の間隔で導電性繊維が織り込まれている。誘導型近接センサは、導電性繊維の変位を検出できるように配置されている、制御部は、誘導型近接センサの出力に基づいて手摺ベルトの移動速度を検出する。
The mobile handrail device for a passenger conveyor of the present invention includes a handrail belt formed in an endless shape, an inductive proximity sensor, and a control unit. The handrail belt is provided with a canvas portion arranged on the inner surface side in an endless manner along the moving direction of the handrail belt. Conductive fibers are woven into the canvas portion at regular intervals along the moving direction. The inductive proximity sensor is arranged so that the displacement of the conductive fiber can be detected, and the control unit detects the moving speed of the handrail belt based on the output of the inductive proximity sensor.
手摺ベルトの移動方向に沿って一定の間隔で織り込まれた導電性繊維を検出することで手摺ベルトの移動速度を直接的に計測することができる。従って、ローラの回転数に基づいて移動速度を算出する場合のようにローラの磨耗やすべり等による影響を受けることなく、高い精度で移動速度を検出することができる。また、ローラ等に回転数を検出するための専用部品を設置する必要がなく、導電性繊維の移動を検知できるセンサを設置すれば足りるため、部品点数を少なく抑える事ができると共に、省スペース化を図ることができる。
The moving speed of the handrail belt can be directly measured by detecting conductive fibers woven at regular intervals along the moving direction of the handrail belt. Therefore, the moving speed can be detected with high accuracy without being affected by the wear and slip of the rollers as in the case of calculating the moving speed based on the rotation speed of the rollers. In addition, it is not necessary to install special parts for detecting the number of rotations on the rollers, etc., and it is sufficient to install a sensor that can detect the movement of conductive fibers, so the number of parts can be kept small and space can be saved. Can be planned.

図１に示されるように、エスカレータ１００は、建物の異なる階を跨いで設けられている。エスカレータ１００の上部乗降口と下部乗降口との間は、複数のステップ２が移動する移動通路で結ばれている。複数のステップ２は無端状のステップチェーンに連結されている。ステップチェーンは、駆動装置４によって駆動され、これにより上部乗降口と下部乗降口との間でステップ２を循環移動させる。
As shown in FIG. 1, the escalator 100 is provided across different floors of the building. The upper entrance / exit of the escalator 100 and the lower entrance / exit are connected by a moving passage in which a plurality of steps 2 move. The plurality of steps 2 are connected to an endless step chain. The step chain is driven by the drive device 4, which causes step 2 to circulate between the upper entrance and exit.
移動通路の両側には一対の欄干６が配置されている。欄干６の周縁部には、無端状の手摺ベルト１０が張設されている。手摺ベルト１０は、駆動装置４と同期して回転する手摺用滑車によって、ステップの移動と同期して循環移動するように構成されている。
A pair of balustrades 6 are arranged on both sides of the moving passage. An endless handrail belt 10 is stretched around the peripheral edge of the balustrade 6. The handrail belt 10 is configured to circulate in synchronization with the movement of the step by a pulley for the handrail that rotates in synchronization with the drive device 4.

FIG. 2 is a view showing a cross section perpendicular to the moving direction of the handrail belt 10, FIG. 3 is a perspective view schematically showing the inner surface side of the handrail belt 10, and FIG. 4 is a perspective view of the handrail belt of FIG. It is a plan view seen from below. As shown in FIG. 2, the cross section of the handrail belt 10 perpendicular to the moving direction is formed in a substantially C shape. The surface side of the handrail belt 10 is formed of, for example, a resin such as a thermoplastic elastomer.
手摺ベルト１０の内面側には手摺案内レールが設置される。手摺ベルト１０の内面側は帆布で形成された帆布部１２で覆われている。帆布部１２には、図３及び図４に示されるように、導電性繊維が織り込まれ形成された複数の導電部１４が形成されている。導電性繊維は、例えば、カーボンファイバーである。
A handrail guide rail is installed on the inner surface side of the handrail belt 10. The inner surface side of the handrail belt 10 is covered with a canvas portion 12 formed of canvas. As shown in FIGS. 3 and 4, a plurality of conductive portions 14 formed by weaving conductive fibers are formed on the canvas portion 12. The conductive fiber is, for example, carbon fiber.
各導電部１４の導電性繊維は、手摺ベルト１０の移動方向に垂直な方向に、帆布部１２の端部１２Ａから１２Ｂに至るまで一続きに織り込まれている。つまり、各導電部１４は、手摺ベルト１０の移動方向に垂直な面に、これにより、手摺ベルト１０の移動方向に対し直行する方向に、端部１２ＡからＣ字形状に形成されている。
The conductive fibers of each conductive portion 14 are continuously woven from the end portions 12A to 12B of the canvas portion 12 in the direction perpendicular to the moving direction of the handrail belt 10. That is, each conductive portion 14 is formed in a C shape from the end portion 12A on a surface perpendicular to the moving direction of the handrail belt 10 in a direction perpendicular to the moving direction of the handrail belt 10.
また、複数の導電部１４は、手摺ベルト１０の移動方向に対し垂直な方向に、互いに同一の幅で形成され、かつ、等間隔で配置されている。導電部１４と導電部１４との間隔は、例えば、２０～５０ｍｍである。
Further, the plurality of conductive portions 14 are formed in the direction perpendicular to the moving direction of the handrail belt 10 with the same width as each other, and are arranged at equal intervals. The distance between the conductive portion 14 and the conductive portion 14 is, for example, 20 to 50 mm.

FIG. 5 is a diagram schematically showing the configuration of the moving handrail device. As shown in FIG. 5, the mobile handrail device of the present embodiment includes the handrail belt 10 and an inductive proximity sensor 20 and a control unit 30 installed in the vicinity of the handrail belt 10. As the inductive proximity sensor 20, for example, a magnetic inductive proximity sensor such as an overcurrent displacement sensor can be used. However, the inductive proximity sensor 20 may be of any type as long as it can detect the displacement of the conductive portion 14 of the handrail belt 10.
誘導型近接センサ２０は制御部３０に接続されている。制御部３０には、誘導型近接センサ２０の検出値が入力され、これに基づいて、手摺ベルト１０の移動速度を算出する。具体的に、例えば、一定の時間内における導電部１４の検出回数と導電部１４の設置間隔とに基づいて、手摺ベルト１０の移動速度を算出する。あるいは、ある導電部１４が検出されてから次の導電部１４が検出されるまでの時間と、導電部１４の設置間隔とに基づいて、手摺ベルト１０の移動速度を計測する構成であってもよい。
The inductive proximity sensor 20 is connected to the control unit 30. The detection value of the inductive proximity sensor 20 is input to the control unit 30, and the moving speed of the handrail belt 10 is calculated based on this. Specifically, for example, the moving speed of the handrail belt 10 is calculated based on the number of times the conductive portion 14 is detected within a certain time and the installation interval of the conductive portion 14. Alternatively, even in a configuration in which the moving speed of the handrail belt 10 is measured based on the time from the detection of a certain conductive portion 14 to the detection of the next conductive portion 14 and the installation interval of the conductive portion 14. Good.
以上説明したように、本実施の形態によれば、専用のローラ等を設置することなく、誘導型近接センサ２０の出力に基づいて手摺ベルト１０の移動速度を直接的に検出することができる。従って、ローラの磨耗や回転不良等による影響を受けることなく、高い精度で手摺ベルト１０の移動速度を検出することができる。
As described above, according to the present embodiment, the moving speed of the handrail belt 10 can be directly detected based on the output of the inductive proximity sensor 20 without installing a dedicated roller or the like. Therefore, the moving speed of the handrail belt 10 can be detected with high accuracy without being affected by roller wear, rotation failure, or the like.
なお、本実施の形態では、導電部１４が、移動方向に対して垂直な面において、帆布部１２の端部１２Ａから端部１２Ｂまで一続きに導電性繊維が織り込まれることで構成されている場合について説明した。しかし、導電部１４の配置は、これに限られない。例えば、手摺ベルト１０の移動方向に垂直な断面において、帆布部１２の一部分のみに導電性繊維が織り込まれることで導電部１４が形成されているものであってもよい。この場合であっても、導電部１４は、移動方向に沿って一定の間隔で複数配置される。また、移動方向に垂直な断面において、帆布部１２の一部分にのみ導電性繊維を織り込む場合、導電性繊維が織り込まれる部分は、移動方向に複数配置される導電部１４の断面それぞれで同一の位置とすることが好ましい。
In the present embodiment, the conductive portion 14 is configured such that conductive fibers are continuously woven from the end portion 12A to the end portion 12B of the canvas portion 12 on a surface perpendicular to the moving direction. The case was explained. However, the arrangement of the conductive portion 14 is not limited to this. For example, in a cross section perpendicular to the moving direction of the handrail belt 10, the conductive portion 14 may be formed by weaving conductive fibers only in a part of the canvas portion 12. Even in this case, a plurality of conductive portions 14 are arranged at regular intervals along the moving direction. Further, in the cross section perpendicular to the moving direction, when the conductive fibers are woven only in a part of the canvas portion 12, the portions where the conductive fibers are woven are at the same position in each of the cross sections of the conductive portions 14 arranged in the moving direction. Is preferable.
また、図５では、制御部３０が、誘導型近接センサ２０の外部に設置された構成について説明した。しかしながら、手摺ベルト１０の移動速度を算出する制御部３０としての機能は、誘導型近接センサ２０に内蔵された構成であってもよい。
Further, in FIG. 5, the configuration in which the control unit 30 is installed outside the inductive proximity sensor 20 has been described. However, the function as the control unit 30 for calculating the moving speed of the handrail belt 10 may be a configuration built in the inductive proximity sensor 20.
