In each figure, the same or corresponding parts are designated by the same reference numerals. The duplicate description of the relevant part will be simplified or omitted as appropriate.
実施の形態１．
　図１は実施の形態１における乗客コンベアのステップチェーンの伸び検知システムが適用される乗客コンベアの正面図である。 Embodiment 1.
FIG. 1 is a front view of a passenger conveyor to which the extension detection system of the step chain of the passenger conveyor according to the first embodiment is applied.
　図１に示されるように、下部乗降口１は、乗客コンベアの下部に設けられる。上部乗降口２は、乗客コンベアの上部に設けられる。複数のステップ３は、下部乗降口１と上部乗降口２との間に設けられる。左側のステップチェーン４は、複数のステップ３の左側を連結する。右側のステップチェーン４は、複数のステップ３の右側を連結する。 As shown in FIG. 1, the lower entrance / exit 1 is provided at the lower part of the passenger conveyor. The upper entrance / exit 2 is provided at the upper part of the passenger conveyor. The plurality of steps 3 are provided between the lower entrance / exit 1 and the upper entrance / exit 2. The step chain 4 on the left side connects the left sides of the plurality of steps 3. The step chain 4 on the right side connects the right sides of the plurality of steps 3.
　一対のステップチェーン４は、図示されないスプロケットの回転に追従して循環移動する。複数のステップ３は、一対のステップチェーン４の循環移動に追従して循環移動する。 The pair of step chains 4 circulate and move following the rotation of a sprocket (not shown). The plurality of steps 3 circulate and move following the circular movement of the pair of step chains 4.
　次に、図２を用いて、ステップチェーン４の部分伸びを説明する。
　図２は実施の形態１における乗客コンベアのステップチェーンの伸び検知システムが適用されるステップチェーンの拡大斜視図である。 Next, the partial elongation of the step chain 4 will be described with reference to FIG.
FIG. 2 is an enlarged perspective view of a step chain to which the extension detection system of the step chain of the passenger conveyor according to the first embodiment is applied.
　図２に示されるように、ステップチェーン４は、ピン４ａがブシュ４ｂに挿入されることで連結される。例えば、隣接したステップ３に対応した位置においては、大きな張力がかかる。この際、ピン４ａおよびブシュ４ｂが摩耗により削れる。その結果、隣接したリンクの間の距離が伸びる。リンクの間の距離が伸びは、ステップチェーン４の伸びとして現われる。 As shown in FIG. 2, the step chain 4 is connected by inserting the pin 4a into the bush 4b. For example, a large tension is applied at the position corresponding to the adjacent step 3. At this time, the pin 4a and the bush 4b are scraped due to wear. As a result, the distance between adjacent links increases. The extension of the distance between the links appears as the extension of the step chain 4.
　次に、図３を用いて、ステップチェーン４の部分伸びが発生した際のステップ３の状態を説明する。
　図３は実施の形態１における乗客コンベアのステップチェーンの伸び検知システムが適用されるステップチェーンの拡大斜視図である。 Next, the state of step 3 when the partial elongation of the step chain 4 occurs will be described with reference to FIG.
FIG. 3 is an enlarged perspective view of a step chain to which the extension detection system of the step chain of the passenger conveyor according to the first embodiment is applied.
　図３に示されるように、左側および右側のステップチェーン４が伸びていない正常の状態においては、隣接したステップ３の間隔は、一対のスカートガード５の間で幅方向において均一となる。左側のステップチェーン４の部分伸びが発生した状態においては、隣接したステップ３の左側の間隔が広がる。右側のステップチェーン４の部分伸びが発生した状態においては、隣接したステップ３の右側の間隔が広がる。 As shown in FIG. 3, in the normal state where the left and right step chains 4 are not extended, the distance between the adjacent step 3s is uniform in the width direction between the pair of skirt guards 5. In the state where the step chain 4 on the left side is partially stretched, the distance on the left side of the adjacent step 3 is widened. In the state where the step chain 4 on the right side is partially stretched, the distance on the right side of the adjacent step 3 is widened.
　次に、図４を用いて、ステップチェーン４の伸びを検知する方法を説明する。
　図４は実施の形態１における乗客コンベアのステップチェーンの伸び検知システムの構成図である。 Next, a method of detecting the elongation of the step chain 4 will be described with reference to FIG.
FIG. 4 is a configuration diagram of an extension detection system for the step chain of the passenger conveyor according to the first embodiment.
　伸び検知システムは、カメラ６と伸び検知装置７とを備える。 The stretch detection system includes a camera 6 and a stretch detection device 7.
　カメラ６は、下部乗降口１の付近で乗客コンベアの上方からステップ３を見下ろすように一時的に配置される。 The camera 6 is temporarily arranged near the lower entrance 1 so as to look down on step 3 from above the passenger conveyor.
　伸び検知装置７は、傾き検知部７ａと伸び検知部７ｂとを備える。 The stretch detection device 7 includes a tilt detection unit 7a and a stretch detection unit 7b.
　例えば、傾き検知部７ａは、カメラ６からの画像に基づいて複数のステップ３が循環移動している際における往路側のステップ３の傾きを検知する。この際、傾き検知部７ａは、ステップ３のクリートの端部を直線部分として抽出したうえでステップ３のずれを定量化する。伸び検知部７ｂは、傾き検知部が検知したステップ３の傾きに基づいて、図４においては図示されないステップチェーン４の伸び有無または度合を検知する。 For example, the tilt detection unit 7a detects the tilt of step 3 on the outward route side when a plurality of steps 3 are cyclically moving based on the image from the camera 6. At this time, the inclination detection unit 7a extracts the end portion of the cleat in step 3 as a straight line portion and then quantifies the deviation in step 3. The elongation detection unit 7b detects the presence / absence or degree of extension of the step chain 4 (not shown in FIG. 4) based on the inclination of step 3 detected by the inclination detection unit.
　次に、図５を用いて、伸び検知装置７の動作の概要を説明する。
　図５は実施の形態１における乗客コンベアのステップチェーンの伸び検知システムの一部である伸び検知装置の動作の概要を説明するためのフローチャートである。 Next, the outline of the operation of the elongation detection device 7 will be described with reference to FIG.
FIG. 5 is a flowchart for explaining an outline of the operation of the stretch detection device which is a part of the stretch detection system of the step chain of the passenger conveyor in the first embodiment.
　ステップＳ１では、伸び検知装置７は、乗客コンベアの下降運転が実施されている状態でカメラ６から複数のステップ３の画像の入力を受け付ける。その後、伸び検知装置７は、ステップＳ２の動作を行う。ステップＳ２では、伸び検知装置７は、隣接したステップ３の隙間が図示されないステップガイドに入る手前の状態を撮影した画像フレームをカメラの画像から抽出する。 In step S1, the elongation detection device 7 receives input of a plurality of images of step 3 from the camera 6 while the passenger conveyor is being lowered. After that, the elongation detection device 7 performs the operation of step S2. In step S2, the stretch detection device 7 extracts from the camera image an image frame in which the gap in the adjacent step 3 is taken before entering the step guide (not shown).
　その後、伸び検知装置７は、ステップＳ３の動作を行う。ステップＳ３では、伸び検知装置７は、隣接したステップ３の隙間が写った部分を画像フレームから抽出する。その後、ステップＳ４の動作を行う。ステップＳ４では、伸び検知装置７は、隣接したステップ３の隙間の長さを隣接したステップ３の隙間が写った部分の画素数から検知する。その後、伸び検知装置７は、ステップＳ５の動作を行う。ステップＳ５では、伸び検知装置７は、隣接したステップ３の隙間の左側と右側との差を検知する。その結果、隣接したステップ３の平行度合が検知される。 After that, the elongation detection device 7 performs the operation of step S3. In step S3, the stretch detection device 7 extracts a portion of the adjacent step 3 in which the gap is captured from the image frame. After that, the operation of step S4 is performed. In step S4, the elongation detection device 7 detects the length of the gap in the adjacent step 3 from the number of pixels in the portion where the gap in the adjacent step 3 is reflected. After that, the elongation detection device 7 performs the operation of step S5. In step S5, the elongation detection device 7 detects the difference between the left side and the right side of the gap in the adjacent step 3. As a result, the degree of parallelism of the adjacent step 3 is detected.
　以上で説明した実施の形態１によれば、伸び検知装置７は、ステップ３の傾きに基づいてステップチェーン４の伸びを検知する。このため、乗客コンベアに新たな機器を追加することなく、ステップチェーン４の部分伸びを容易に検知することができる。 According to the first embodiment described above, the elongation detection device 7 detects the elongation of the step chain 4 based on the inclination of the step 3. Therefore, the partial elongation of the step chain 4 can be easily detected without adding new equipment to the passenger conveyor.
　具体的には、伸び検知装置７は、カメラ６の画像に基づいて、ステップ３の隣接したステップの隙間の左側と右側との差からステップ３の傾きを検知する。このため、ステップチェーン４の伸びを検知する際に必要な情報を容易に取得することができる。 Specifically, the elongation detection device 7 detects the inclination of step 3 from the difference between the left side and the right side of the gap between the adjacent steps in step 3 based on the image of the camera 6. Therefore, it is possible to easily acquire the information necessary for detecting the elongation of the step chain 4.
　この際、乗客コンベアは、通常運転を維持していてもよい。このため、乗客コンベアの運行効率を下げることなく、ステップチェーン４の伸びを容易に検知することができる。 At this time, the passenger conveyor may maintain normal operation. Therefore, the elongation of the step chain 4 can be easily detected without lowering the operation efficiency of the passenger conveyor.
　なお、隣接するステップ３の隙間を計測する測距センサの計測結果に基づいて、ステップ３の隣接したステップの隙間の左側と右側との差からステップ３の傾きを検知してもよい。この場合も、ステップチェーン４の伸びを検知する際に必要な情報を容易に取得することができる。 Note that, based on the measurement result of the distance measuring sensor that measures the gap of the adjacent step 3, the inclination of step 3 may be detected from the difference between the left side and the right side of the gap of the adjacent step of step 3. Also in this case, the information necessary for detecting the elongation of the step chain 4 can be easily acquired.
　また、カメラ６の画像に基づいて、当該ステップ３のクリートの方向のステップ３ごとの変化からステップ３の傾きを検知してもよい。この場合も、ステップチェーン４の伸びを検知する際に必要な情報を容易に取得することができる。 Further, the inclination of step 3 may be detected from the change of the cleat direction of step 3 for each step 3 based on the image of the camera 6. Also in this case, the information necessary for detecting the elongation of the step chain 4 can be easily acquired.
　また、ステップ３のクリートの方向に軸を合わせて当該ステップ３に固定された振動センサの計測結果に基づいて、当該ステップ３のクリートの方向のステップ３ごとの変化からステップ３の傾きを検知してもよい。この場合も、ステップチェーン４の伸びを検知する際に必要な情報を容易に取得することができる。 Further, the inclination of step 3 is detected from the change of the cleat direction of step 3 for each step 3 based on the measurement result of the vibration sensor fixed in the step 3 by aligning the axis with the direction of the cleat of step 3. You may. Also in this case, the information necessary for detecting the elongation of the step chain 4 can be easily acquired.
　また、カメラ６の画像に基づいて、ステップ３の移動方向と当該ステップ３のクリートとの方向の差から当該ステップ３の傾きを検知してもよい。この場合も、ステップチェーン４の伸びを検知する際に必要な情報として、トラスレールに対する当該ステップ３の傾きを容易に取得することができる。 Further, the inclination of the step 3 may be detected from the difference between the moving direction of the step 3 and the direction of the cleat of the step 3 based on the image of the camera 6. Also in this case, the inclination of the step 3 with respect to the truss rail can be easily acquired as the information necessary for detecting the elongation of the step chain 4.
　また、ステップ３のクリートの方向に軸を合わせて当該ステップ３に固定された振動センサの計測結果に基づいて、ステップ３の移動方向と当該ステップ３のクリートとの方向の差から当該ステップ３の傾きを検知してもよい。この場合も、ステップチェーン４の伸びを検知する際に必要な情報として、トラスレールに対する当該ステップ３の傾きを容易に取得することができる。 Further, based on the measurement result of the vibration sensor fixed in the step 3 by aligning the axis with the direction of the cleat in the step 3, the difference between the moving direction of the step 3 and the direction of the cleat in the step 3 indicates that the step 3 is performed.
