Description

本発明は、エスカレータや移動歩道等の乗客コンベアに備えられる移動手摺の内部劣化を診断する際に用いられる乗客コンベアの移動手摺探傷装置に関する。   The present invention relates to a moving handrail flaw detector for a passenger conveyor used for diagnosing internal deterioration of a moving handrail provided in a passenger conveyor such as an escalator or a moving walkway.

一般に乗客コンベアには、乗客を乗せて移動するステップと、このステップと同期して移動する移動手摺とが設けられ、移動手摺の内部には抗張体となるスチールコードが埋設されている。この移動手摺内のスチールコードは経年的に損傷し、移動手摺の表面に飛び出す不具合を生じることもある。このため、スチールコードの状態を定期的に診断することが行なわれている。   In general, a passenger conveyor is provided with a step of moving with passengers and a moving handrail moving in synchronization with this step, and a steel cord serving as a tensile body is embedded in the moving handrail. The steel cord in the moving handrail may be damaged over time and may cause a problem of popping out on the surface of the moving handrail. For this reason, the status of the steel cord is regularly diagnosed.

この診断方法として、従来、移動手摺へＸ線を照射して、移動手摺の内部の透写画像を取得し、この取得した画像によってスチールコードの損傷状態を診断する方法が知られている（特許文献１参照）。   As this diagnostic method, there is conventionally known a method of irradiating a moving handrail with X-rays to acquire a translucent image inside the moving handrail and diagnosing a damaged state of the steel cord based on the acquired image (patent) Reference 1).

ところで、前述の診断方法において、移動手摺の各部の位置または速度情報と、前述した画像とを照らし合せないと移動手摺のどの部位のスチールコードが損傷しているかを判定することができない。   By the way, in the above-described diagnosis method, it is impossible to determine which part of the moving handrail is damaged unless the position or speed information of each part of the moving handrail is compared with the above-described image.

従来、移動手摺の速度情報を得る方法としては、光学的手段を用いて移動手摺の直交座標、または極座標を検知し、その移動量に基づき移動速度と速度変動を同時に検出する装置が提案されている（特許文献２参照）。   Conventionally, as a method for obtaining speed information of a moving handrail, an apparatus has been proposed that detects the orthogonal coordinates or polar coordinates of the moving handrail using optical means, and simultaneously detects the moving speed and the speed fluctuation based on the amount of movement. (See Patent Document 2).

前述した特許文献２に示される従来技術では、光学マウスポジションセンサを移動手摺に接触させて、移動手摺の移動量を座標として検知しているが、この方法では移動手摺の表面の状態により計測誤差が出てしまう不具合がある。特に移動手摺の表面に経年劣化により亀裂や欠損等が生じている場合は、光学マウスポジションセンサの計測誤差が大きくなってしまう。したがって、移動手摺の各部の位置あるいは速度を正確に検出することが難しくなる。   In the prior art disclosed in Patent Document 2 described above, an optical mouse position sensor is brought into contact with a moving handrail and the amount of movement of the moving handrail is detected as a coordinate. However, in this method, a measurement error is caused by the state of the surface of the moving handrail. There is a problem that appears. In particular, when the surface of the moving handrail is cracked or missing due to aging, the measurement error of the optical mouse position sensor becomes large. Therefore, it is difficult to accurately detect the position or speed of each part of the moving handrail.

このように構成した本発明は、ローラと光学式検出手段とが共に状態検出手段に取り付けられ、ローラと光学式検出手段とが移動手摺に対する状態検出手段の移動または相対的移動に伴って一体的に変位することと、ローラが移動手摺の上を回転することに伴う光学式検出手段によるローラの回転変位量の検出とにより、前述した移動手摺の表面の経年劣化の影響が抑えられ、移動手摺の各部の位置あるいは速度の計測誤差を少なくすることができる。   In the present invention configured as described above, the roller and the optical detection unit are both attached to the state detection unit, and the roller and the optical detection unit are integrated with the movement or relative movement of the state detection unit with respect to the moving handrail. , And the detection of the rotational displacement amount of the roller by the optical detection means accompanying the rotation of the roller on the moving handrail, the influence of the above-mentioned aging deterioration of the surface of the moving handrail is suppressed, and the moving handrail is suppressed. The measurement error of the position or speed of each part can be reduced.

また、本発明は、前記発明において、前記光学式検出手段は、マウスベース上に搭載される光学マウスから成り、前記マウスベースに、このマウスベースが前記移動手摺に接触することを防止する補助ローラを設けたことを特徴としている。このように構成した本発明は、マウスベースの接触による移動手摺の損傷を防ぐことができる。   In the present invention, the optical detection means comprises an optical mouse mounted on a mouse base. The auxiliary roller for preventing the mouse base from contacting the moving handrail. It is characterized by providing. The present invention configured as described above can prevent the handrail from being damaged by the contact of the mouse base.

図１は本発明に係る乗客コンベアの移動手摺探傷装置の一実施形態を示す側面図である。   FIG. 1 is a side view showing an embodiment of a moving handrail flaw detector for a passenger conveyor according to the present invention.

本実施形態に係る移動手摺探傷装置は、例えばＸ線探傷装置であり、Ｘ線発生源である放射線発生器１と、この放射線発生器１から出射されるＸ線の透過光を入射する受光部３
とを備えている。放射線発生器１と受光部３とは、乗客コンベアの移動手摺２を挟むように互いに一体的に配置されて、移動手摺２の内部に埋設されたスチールコードの状態を検出する状態検出手段を構成している。 The moving handrail flaw detector according to this embodiment is, for example, an X-ray flaw detector, and a radiation generator 1 that is an X-ray generation source and a light receiving unit that receives X-ray transmitted light emitted from the radiation generator 1 3
And. The radiation generator 1 and the light receiving unit 3 are arranged integrally with each other so as to sandwich the moving handrail 2 of the passenger conveyor, and constitute state detecting means for detecting the state of the steel cord embedded in the moving handrail 2 is doing.

受光部３の内部には、蛍光紙すなわちシンチレータ３ａと、このシンチレータ３ａの透過画像を反射させる反射板３ｂと、この反射板３ｂからの映像を撮影するカメラ３ｃとが配置されている。   Inside the light receiving unit 3, fluorescent paper, that is, a scintillator 3a, a reflection plate 3b that reflects a transmission image of the scintillator 3a, and a camera 3c that captures an image from the reflection plate 3b are arranged.

また、本実施形態は、カメラ３ｃで撮影した画像をデジタルに変換するビデオキャプチャ４と、このビデオキャプチャ４で変換された画像を格納するパソコン５とを備えている。   In addition, the present embodiment includes a video capture 4 that converts an image captured by the camera 3c into digital, and a personal computer 5 that stores the image converted by the video capture 4.

さらに本実施形態は、状態検出手段を構成する例えば受光部３に取り付けられ、移動手摺２に当接し、移動手摺２の移動または相対的移動に伴って回転する後述のローラ６ｄと、受光部３に取り付けられ、ローラ６ｄの回転変位量を検出する光学式検出手段、例えば後述のワイヤレス光学マウス６ａと、前述したパソコン５に含まれ、受光部３の状態検出結果とワイヤレス光学マウス６ａの状態検出結果とを照合し、この照合によって選択された受光部３の状態検出結果を連続的に接合する処理を行う照合手段とを備えている。ローラ６ｄとワイヤレス光学マウス６ａは、受光部３に取り付けられる距離計測用光学マウス６に含まれている。   Furthermore, in the present embodiment, a later-described roller 6d that is attached to, for example, the light receiving unit 3 constituting the state detection unit, contacts the moving handrail 2 and rotates with the movement or relative movement of the moving handrail 2, and the light receiving unit 3 The optical detection means for detecting the rotational displacement amount of the roller 6d, for example, the wireless optical mouse 6a described later, and the state detection result of the light receiving unit 3 and the state detection of the wireless optical mouse 6a are included in the personal computer 5 described later. A collating unit that collates the results and performs a process of continuously joining the state detection results of the light receiving units 3 selected by the collation. The roller 6 d and the wireless optical mouse 6 a are included in the distance measuring optical mouse 6 attached to the light receiving unit 3.

図２は本実施形態に備えられる距離計測用光学マウスを示す側面図である。   FIG. 2 is a side view showing the optical mouse for distance measurement provided in this embodiment.

この図２に示すように、距離計測用光学マウス６は、前述したローラ６ｄが取り付けられるマウスベース６ｂと、このマウスベース６ｂ上に搭載される前述のワイヤレス光学マウス６ａと、受光部３に接着されるマグネット６ｆと、一端をこのマグネット６ｆに相対的に回動可能に連結され、他端をマウスベース６ｂに相対的に回転可能に連結されるリンク６ｆとを備えている。また、この距離計測用光学マウス６は、マウスベース６ｂの両端のそれぞれに設けられ、ローラ６ｄを移動手摺２上に載置した状態にあって、マウスベース２が移動手摺２に当接することを防止する補助ローラ６ｃと、ワイヤレス光学マウス６ａの上方への飛び出しを規制する固定カバー６ｅとを備えている。なお、ローラ６ｄは例えば金属から成り、表面に移動手摺２との摩擦力を確保するための荒仕上げ加工が施されている。また、ローラ６ｄとマウスベース６ｂとの間隔は、可能な限り小さい寸法に設定してある。   As shown in FIG. 2, the distance measuring optical mouse 6 is bonded to the light receiving unit 3 with the mouse base 6b to which the roller 6d described above is attached, the wireless optical mouse 6a mounted on the mouse base 6b, and the light receiving unit 3. And a link 6f having one end rotatably connected to the magnet 6f and the other end rotatably connected to the mouse base 6b. The distance measuring optical mouse 6 is provided at each of both ends of the mouse base 6b, and the mouse base 2 is in contact with the moving handrail 2 while the roller 6d is placed on the moving handrail 2. An auxiliary roller 6c for preventing and a fixed cover 6e for restricting the wireless optical mouse 6a from protruding upward are provided. The roller 6d is made of, for example, metal, and has a rough finishing process for securing a frictional force with the moving handrail 2 on the surface. The distance between the roller 6d and the mouse base 6b is set as small as possible.

移動手摺２の内部のスチールコードの状態の検出に際しては、例えば静止させた移動手摺２に対して、放射線発生器１と受光部３とから成る状態検出手段を移動させることによって行われる。放射線発生器１からＸ線を移動手摺２に照射することにより、受光部３のシンチレータ３ａ、反射板３ｂ、カメラ３ｃ、及びビデオキャプチャ４を介して移動手摺２の内部の画像が求められ、この画像がパソコン５の透写画像として格納される。   When detecting the state of the steel cord inside the moving handrail 2, for example, the state detecting means including the radiation generator 1 and the light receiving unit 3 is moved with respect to the stationary moving handrail 2. By irradiating the moving handrail 2 with X-rays from the radiation generator 1, an image inside the moving handrail 2 is obtained via the scintillator 3a, the reflector 3b, the camera 3c, and the video capture 4 of the light receiving unit 3. The image is stored as a transparent image of the personal computer 5.

また、前述した状態検出手段の移動に追従してローラ６ｄが移動手摺２上を回転し、同時にワイヤレス光学マウス６ａが移動する。これによって距離計測用光学マウス６の移動距離、すなわち放射線発生器１と受光部３を含む状態検出手段の移動距離が計測され、この移動距離がワイヤレス光学マウス６からパソコン５に送信され、このパソコン５に移動距離データとして格納される。   Further, the roller 6d rotates on the moving handrail 2 following the movement of the state detecting means described above, and at the same time, the wireless optical mouse 6a moves. Thereby, the moving distance of the optical mouse 6 for distance measurement, that is, the moving distance of the state detecting means including the radiation generator 1 and the light receiving unit 3 is measured, and this moving distance is transmitted from the wireless optical mouse 6 to the personal computer 5. 5 is stored as movement distance data.

図３は本実施形態に備えられるパソコンに含まれる照合手段の処理内容を示す図である。   FIG. 3 is a diagram showing the processing contents of the collating means included in the personal computer provided in this embodiment.

この図３において、７は移動手摺２内の透写動画、７ａ〜７ｆは透写動画を変換して形成した１枚ずつの静止画、８はワイヤレス光学マウス６ａの移動距離データ群、８ａ〜８ｆは移動距離データ群８を１レコードずつに分割した分割データ、９はパノラマ画で、このパノラマ画９は静止画７ａ〜７ｆと移動距離データ群８ａ〜８ｆとを照合して接合したものである。   In FIG. 3, 7 is a moving image in the moving handrail 2, 7a to 7f are still images formed by converting the moving image, 8 is a moving distance data group of the wireless optical mouse 6a, and 8a to 8f. 8f is divided data obtained by dividing the moving distance data group 8 for each record, 9 is a panoramic image, and the panoramic image 9 is obtained by collating the still images 7a to 7f and the moving distance data groups 8a to 8f. is there.

移動手摺２内の透写動画７は、前述のように１枚ずつの静止画７ａ〜７ｆに分割されるが、これらの静止画７ａ〜７ｆには記録開始からの時間が付与される。このように付与された時間は、同図３中の静止画７ａ〜７ｆそれぞれの下段に０ｓ（秒）〜０．５ｓ（秒）として示されている。また、ワイヤレス光学マウス６ａによって検出された移動距離データ群８にも同様に、１レコードずつに分割された分割データ８ａ〜８ｆごとに、記録開始からの時間が付与される。このように付与された時間は、同図３中の分割データ８ａ〜８ｆの下段に０ｓ（秒）〜０．５ｓ（秒）として示されている。なお、移動距離データ群８ａ〜８ｆにおいて、移動手摺２の各部とワイヤレス光学マウス６ａとの相対的移動距離１〜３ｍｍと示されている。   The transparent moving image 7 in the moving handrail 2 is divided into still images 7a to 7f one by one as described above, and time from the start of recording is given to these still images 7a to 7f. The time given in this way is shown as 0 s (seconds) to 0.5 s (seconds) in the lower stage of each of the still images 7a to 7f in FIG. Similarly, the moving distance data group 8 detected by the wireless optical mouse 6a is given time from the start of recording for each of the divided data 8a to 8f divided into one record. The time given in this way is shown as 0 s (seconds) to 0.5 s (seconds) in the lower part of the divided data 8a to 8f in FIG. In the movement distance data groups 8a to 8f, the relative movement distance of 1 to 3 mm between each part of the moving handrail 2 and the wireless optical mouse 6a is shown.

前述した分割データ８ａ〜８ｆに対応した静止画７ａ〜７ｆを取り出し並べることによって、パノラマ画９が作成される。すなわち、移動距離データ群８ａ〜８ｆのうちの８ｂ，８ｅ，８ｆは、移動手摺２がそれ以前の時期から移動していないことが示されているので、その時点で録画された静止画７ｂ，７ｅ，７ｆは削除される。残りの静止画７ａ，７ｃ，７ｄを接合することによって連続したパノラマ画９が作成される。   The panorama image 9 is created by taking out and arranging the still images 7a to 7f corresponding to the divided data 8a to 8f. That is, 8b, 8e, and 8f of the moving distance data groups 8a to 8f indicate that the moving handrail 2 has not moved from the previous time, so that the still image 7b recorded at that time is recorded. 7e and 7f are deleted. A continuous panoramic image 9 is created by joining the remaining still images 7a, 7c, and 7d.

作業者が放射線発生器１と受光部３とから成る状態検出手段を手で移動させて移動手摺２の内部に埋設されたスチールコードの状態を検出する作業を行おうとする場合、その移動速度を一定に保つことはできない。したがって、撮影した動画を１枚ずつ貼り合わせたときに重複し、移動手摺２内のスチールコードの状態を正しく表示することはできない。しかし、本実施形態にあっては、状態検出手段に取り付けた距離計測用光学マウス６の移動に伴ってＸ線透写画像を撮影し、図３に示すようにパノラマ画９を作成することにより、作業者が不規則な速度で状態検出手段を移動させて作業を行った場合でも、容易に移動手摺２内のスチールコードの全体の状態を把握することができる。   When an operator tries to detect the state of the steel cord embedded in the moving handrail 2 by manually moving the state detecting means including the radiation generator 1 and the light receiving unit 3, the moving speed is set as follows. It cannot be kept constant. Accordingly, when the captured moving images are pasted one by one, they are duplicated and the state of the steel cord in the moving handrail 2 cannot be displayed correctly. However, in the present embodiment, an X-ray transmission image is taken with the movement of the distance measuring optical mouse 6 attached to the state detecting means, and a panoramic image 9 is created as shown in FIG. Even when the operator moves the state detection means at an irregular speed and performs the work, the entire state of the steel cord in the moving handrail 2 can be easily grasped.

なお、パノラマ画９を作成するときの移動距離誤差については、作業者が予め決めた距離を移動させるように制限し、ワイヤレス光学マウス６ａが出力した移動距離を、この予め決めた距離で逆算し補正を行うことでその誤差を少なくし、計測精度を高めることができる。   Note that the movement distance error when creating the panorama image 9 is limited so that the operator moves a predetermined distance, and the movement distance output by the wireless optical mouse 6a is calculated backward by this predetermined distance. By performing the correction, the error can be reduced and the measurement accuracy can be increased.

このように構成した本実施形態によれば、ローラ６ｄとワイヤレス光学マウス６ａとが共に、放射線発生器１と受光部３とから成る状態検出手段にリンク６ｆ等を介して取り付けられ、ローラ６ａとワイヤレス光学マウス６ａとが移動手摺２に対する状態検出手段の移動に伴って一体的に変位することと、ローラ６ｄが移動手摺２の上を回転することに伴うワイヤレス光学マウス６ａによるローラ６ａの回転変位量の検出と、マウスベース６ｂとローラ６ｄとの間隔を極めて小さく設定してあることとにより、移動手摺２の表面の経年劣化の影響が抑えられ、移動手摺２の各部の位置の計測誤差を少なくすることができ、移動手摺２の各部の位置を正確に検出することができる。したがって、移動手摺２の表面に経年劣化を生じている場合でも、状態検出手段によって移動手摺２に埋設されたスチールコードの損傷部位を高精度で検出することができる。なお、上記では移動手摺２の各部の位置を計測するようにしたが、移動手摺２の各部の速度を計測するようにしてもよい。   According to this embodiment configured as described above, both the roller 6d and the wireless optical mouse 6a are attached to the state detecting means including the radiation generator 1 and the light receiving unit 3 via the link 6f or the like, and the roller 6a The wireless optical mouse 6a displaces integrally with the movement of the state detecting means relative to the moving handrail 2, and the rotational displacement of the roller 6a by the wireless optical mouse 6a as the roller 6d rotates on the moving handrail 2. By detecting the amount and setting the distance between the mouse base 6b and the roller 6d to be extremely small, the influence of the aging deterioration of the surface of the moving handrail 2 can be suppressed, and the measurement error of the position of each part of the moving handrail 2 can be reduced. The position of each part of the movable handrail 2 can be accurately detected. Therefore, even when the surface of the moving handrail 2 has deteriorated over time, the damaged portion of the steel cord embedded in the moving handrail 2 can be detected with high accuracy by the state detecting means. In the above description, the position of each part of the moving handrail 2 is measured. However, the speed of each part of the moving handrail 2 may be measured.

また、本実施形態は、固定カバー６ｅによってワイヤレス光学マウス６ａの上方への飛び出しを規制するとともに、金属から成るローラ６ｄの表面に荒仕上げ加工を施してあり、ローラ６ｄを移動手摺２及びワイヤレス光学マウス６ａに密着させての回転が可能にしてあるので、ワイヤレス光学マウス６ａで移動距離が検出されるときの認識パターンを細かく設定することができ、移動距離の出力精度を高めることができる。   Further, in the present embodiment, the fixed cover 6e restricts the wireless optical mouse 6a from projecting upward, and the surface of the roller 6d made of metal is rough-finished. Since it is possible to rotate the mouse 6a in close contact with the mouse 6a, it is possible to finely set a recognition pattern when the movement distance is detected by the wireless optical mouse 6a, and to improve the output accuracy of the movement distance.

また、マウスベース６ｂの両端のそれぞれに補助ローラ６ｃを設けてあるので、マウスベース６ｂの当接による移動手摺２の損傷を防ぎ、信頼性の高い移動手摺探傷装置を実現できる。   Further, since the auxiliary rollers 6c are provided at both ends of the mouse base 6b, it is possible to prevent the moving handrail 2 from being damaged by the contact of the mouse base 6b, and to realize a highly reliable moving handrail flaw detector.

また、小型で安価に入手可能なワイヤレス光学マウス６ａを備えるようにしたことから、当該移動手摺探傷装置の製作費の低減と小型化を実現できる。   In addition, since the wireless optical mouse 6a that is small and can be obtained at low cost is provided, it is possible to reduce the manufacturing cost and downsize the moving handrail flaw detector.

また、パソコン５に含まれる照合手段によって図３に示すようにパノラマ画９を作成できるので、よりスチールコード劣化状態が判別しやすくなり、適切な時期に劣化したスチールコードを交換することができる。   Further, since the panorama image 9 can be created by the verification means included in the personal computer 5 as shown in FIG. 3, the steel cord deterioration state can be more easily determined, and the deteriorated steel cord can be replaced at an appropriate time.

なお、上記実施形態は、リンク６ｆの端部に設けたマグネット６ｇを受光部３に接着させるようにしたが、これに代えて放射線発生器１に接着させるようにしてもよい。   In the above-described embodiment, the magnet 6g provided at the end of the link 6f is bonded to the light receiving unit 3, but it may be bonded to the radiation generator 1 instead.

また、上記では、移動手摺２の内部のスチールコードの状態の検出に際して、放射線発生器１と受光部３とから成る状態検出手段を移動させるようにしたが、このようにせず、状態検出手段を静止させた状態で移動手摺２を移動させて検出を行うようにしてもよい。   In the above description, when detecting the state of the steel cord inside the moving handrail 2, the state detecting means composed of the radiation generator 1 and the light receiving unit 3 is moved. Detection may be performed by moving the moving handrail 2 in a stationary state.

また、上記実施形態は、Ｘ探傷装置によって構成してあるが、磁気探傷装置等によって構成させることもできる。   Moreover, although the said embodiment was comprised by X flaw detector, it can also be comprised by a magnetic flaw detector etc.
