Description

本発明は、エスカレータ等のコンベアに備わる発電装置、及びエスカレータシステムに関する。   The present invention relates to a power generation device provided on a conveyor such as an escalator, and an escalator system.

エスカレータやオートラインなどの乗客コンベアでは、無端状に連結された踏段あるいは踏板が、乗客コンベアの筐体フレームに取り付けられた案内レール上を巡回走行して乗客を搬送する。エスカレータの場合には、図8に示すように、各踏段1ごとに走行方向に向かって前後および左右に合計4個の、上記案内レール上を走行するローラ2a,2b,3a,3bが取り付けられている。この4個のローラ2a,2b,3a,3bは、左右2対、合計4本の案内レール4a,4b,5a,5b上を走行する。   In passenger conveyors such as escalators and auto lines, steps or tread plates connected endlessly travel on a guide rail attached to a casing frame of the passenger conveyor to convey passengers. In the case of an escalator, as shown in FIG. 8, a total of four rollers 2a, 2b, 3a, 3b traveling on the guide rails are attached to each step 1 in the front and rear and left and right directions in the traveling direction. ing. These four rollers 2a, 2b, 3a, 3b travel on a total of four guide rails 4a, 4b, 5a, 5b, two pairs on the left and right.

このようなエスカレータの状態を判定するため、踏段に取り付けられてエスカレータの状態を点検する装置が既に提案されている(例えば、特許文献1)。一方、踏段は、エスカレータの筐体内を周回走行することから、ワイヤ等の固定物を介して上記点検装置へ電力供給するのは困難である。よって、上記点検装置は、自己発電した電力にて作動するように構成されており、上記点検装置に備わる発電部として、図8に示すように、踏段1を形成する側面部材には、上記ローラ3aと接する車輪7を軸端部に設けた発電機6が取り付けられている。よって、踏段1が走行することで、ローラ3aが回転し、該ローラ3aに接する車輪7が転動し、発電機6は発電を行う。   In order to determine the state of such an escalator, a device that is attached to a step and inspects the state of the escalator has already been proposed (for example, Patent Document 1). On the other hand, since the steps travel around the escalator casing, it is difficult to supply power to the inspection device via a fixed object such as a wire. Therefore, the inspection device is configured to operate with self-generated electric power, and as a power generation unit provided in the inspection device, as shown in FIG. A generator 6 provided with a wheel 7 in contact with 3a at the shaft end is attached. Therefore, when the step 1 travels, the roller 3a rotates, the wheel 7 in contact with the roller 3a rolls, and the generator 6 generates power.

特開2006−76729号公報JP 2006-76729 A

上述のように、発電機6の車輪7は、踏段1のローラ3aと接触しており、車輪7とローラ3aとの間で接触摩擦が生じる。よって、大きな振動、騒音が発生するという問題があり、エスカレータの場合には、乗客に不快感を与えてしまうという問題もある。又、上記点検装置に備わりエスカレータの状態検出を行うセンサ部として加速度センサを用いた場合や、音を用いて診断を行う場合には、振動、騒音を抑制する必要がある。   As described above, the wheel 7 of the generator 6 is in contact with the roller 3a of the step 1, and contact friction occurs between the wheel 7 and the roller 3a. Therefore, there is a problem that large vibrations and noises are generated, and in the case of an escalator, there is also a problem that an unpleasant feeling is given to passengers. Further, when an acceleration sensor is used as a sensor unit for detecting the state of the escalator provided in the inspection device, or when diagnosis is performed using sound, it is necessary to suppress vibration and noise.

本発明は、上述のような問題点を解決するためになされたもので、振動、騒音の発生を防止可能な、コンベア用発電装置、及び該コンベア用発電装置を備えたエスカレータシステムを提供することを目的とする。   The present invention has been made to solve the above-described problems, and provides a power generator for a conveyor that can prevent generation of vibration and noise, and an escalator system including the power generator for the conveyor. With the goal.

上記目的を達成するため、本発明は以下のように構成する。
即ち、本発明の第1態様におけるコンベア用発電装置は、複数の踏段を連結してループを形成し、該ループの両端部では上記踏段を上下に反転して上記ループの周回駆動を行うコンベアに備わる発電装置であって、
上記踏段に設けられる保持部材と、
上記保持部材内に設けられ、上記ループの両端部における上記踏段の反転に伴い上記保持部材の軸方向へ上記保持部材内を移動する移動体と、
上記保持部材に設けられ、上記移動体の上記移動に応じて発電を行う発電機構と、
を備え、乗客が搭乗していない上記踏段の反転区間を利用して発電動作を行うことを特徴とする。
In order to achieve the above object, the present invention is configured as follows.
That is, the conveyor power generator according to the first aspect of the present invention is a conveyor that connects a plurality of steps to form a loop, and at both ends of the loop, the steps are turned upside down to rotate the loop. A power generation device,
A holding member provided on the step;
A movable body that is provided in the holding member and moves in the holding member in the axial direction of the holding member as the steps are reversed at both ends of the loop;
A power generation mechanism provided on the holding member and generating power in accordance with the movement of the movable body;
It is characterized by performing electric power generation operation | movement using the inversion area of the said step in which the passenger is not boarding .

本発明の第1態様におけるコンベア用発電装置によれば、踏段が上下に反転することを利用して、踏段に設けた保持部材内を移動体が移動することで発電機構にて発電するように構成したことから、踏段に備わるローラに非接触で、又、ローラの回転とは無関係にて発電を行うことができる。よって振動及び騒音の発生を防止することができる。又、発電は、踏段が上下反転するときのみに行われ、コンベアがエスカレータの形態を採るときであっても、乗客が搭乗可能な区間では上記移動体は移動しない。よって、上記振動及び騒音の発生防止効果と相乗して乗客に不快感を与えることもない。又、保持部材に移動体を設けて発電機構にて発電するという構成ゆえ、簡易な構造とすることができる。   According to the power generation device for a conveyor in the first aspect of the present invention, the power generation mechanism generates power by moving the moving body in the holding member provided on the step by utilizing the fact that the step is turned upside down. Since it is configured, it is possible to generate electric power without contact with the rollers provided in the steps and independently of the rotation of the rollers. Therefore, generation of vibration and noise can be prevented. Further, power generation is performed only when the step is turned upside down, and the moving body does not move in a section in which a passenger can board even when the conveyor takes the form of an escalator. Therefore, there is no unpleasant feeling to the passenger in synergy with the vibration and noise prevention effect. Further, since the moving member is provided on the holding member and the power generation mechanism generates power, the structure can be simplified.

As shown in FIG. 1, the step 101 has a passenger mounting surface 101 a and has a fan-shaped side like the step 201 described above, and the front rollers 2 a and 2 b ( The rear rollers 3a and 3b (collectively "3") are attached to the corners of the arc of the fan on the side opposite to the mounting surface 101a side of the step 101. Is attached). The front rollers 2a and 2b and the rear rollers 3a and 3b are provided in pairs on the left and right and front and rear in the traveling direction of the step 201.

又、搭載面101aの反対側に位置する、踏段101の底部101bには、コンベア用発電装置110が設けられている。本実施形態では、一台の踏段101に、一つのコンベア用発電装置110を設けるが、複数のコンベア用発電装置110を設けても良い。尚、エスカレータシステム200は、少なくとも一つのコンベア用発電装置110を設けた踏段101を複数台配置してもよい。   A conveyor power generator 110 is provided on the bottom 101b of the step 101, which is located on the opposite side of the mounting surface 101a. In this embodiment, one conveyor power generator 110 is provided on one step 101, but a plurality of conveyor power generators 110 may be provided. In the escalator system 200, a plurality of steps 101 provided with at least one conveyor power generation device 110 may be arranged.

コンベア用発電装置110は、複数の踏段を連結して形成したループの両端部にて上記踏段を上下に反転して上記ループの周回駆動を行うコンベアに備わる発電装置であり、保持部材120と、移動体130と、発電機構140とを備える。
保持部材120は、非磁性体にて形成される筒状の部材であり、前ローラ2及び後ローラ3の回転中心を結ぶ傾斜方向102に、当該保持部材120の軸方向を一致又は略一致させて、上記底部101bに設置される。又、保持部材120は、以下に説明する移動体130を内部に収納し、保持部材120の軸方向に沿って移動体130が保持部材120内を滑らかに移動可能なように、移動体130を保持する。又、本実施形態では、移動体130は流動体131であることから、保持部材120は、流動体131の漏れを生じさせない密封構造を有する。さらに、本実施形態では、移動体130は流動体131であることから、保持部材120は、不用意に流動体131が流動するのを防止するように流動体131を堰き止めるとともに、発電機構140に流動体131を効率的に作用させるための堰111を設けている。堰111は、図示するように、保持部材120の両端部における保持部材120の内面にそれぞれ立設され、保持部材120内を保持部材120の略対角線に沿って移動体130が流動して発電機構140に移動体130が効率的に作用するように、堰111と保持部材120の内面との間に形成される開口111aの位置を、2つの堰111で互いに異ならせている。
A power generator 110 for a conveyor is a power generator provided in a conveyor that inverts the steps up and down at both ends of a loop formed by connecting a plurality of steps and drives the loop to rotate, a holding member 120, A moving body 130 and a power generation mechanism 140 are provided.
The holding member 120 is a cylindrical member formed of a non-magnetic material, and the axial direction of the holding member 120 is made to coincide or substantially coincide with the inclined direction 102 connecting the rotation centers of the front roller 2 and the rear roller 3. Installed on the bottom 101b. The holding member 120 accommodates a moving body 130 described below, and the moving body 130 is moved so that the moving body 130 can smoothly move in the holding member 120 along the axial direction of the holding member 120. Hold. In this embodiment, since the moving body 130 is the fluid 131, the holding member 120 has a sealing structure that does not cause the fluid 131 to leak. Furthermore, in the present embodiment, since the moving body 130 is the fluid 131, the holding member 120 dams the fluid 131 so as to prevent the fluid 131 from inadvertently flowing, and the power generation mechanism 140. Is provided with a weir 111 for efficiently operating the fluid 131. As shown in the figure, the weirs 111 are erected on the inner surfaces of the holding member 120 at both ends of the holding member 120, respectively, and the moving body 130 flows along the diagonal line of the holding member 120 in the holding member 120 to generate the power generation mechanism. The positions of the openings 111 a formed between the weir 111 and the inner surface of the holding member 120 are made different from each other by the two weirs 111 so that the moving body 130 acts efficiently on 140.

移動体130は、保持部材120内に設けられ、上記ループ202の両端部に設置されている上部ターミナルギア203及び下部ターミナルギア204における踏段101の姿勢の上下反転に伴い保持部材110内を移動する。上述のように本実施形態では、移動体130は、流動体131にてなり、例えば液体や、粉体、粒状体等を使用する。上述したように、又、図7に示すように、エスカレータシステム200において、踏段101が上部ターミナルギア203及び下部ターミナルギア204に到達したときには、踏段101は、例えば図1に示す状態から図2に示すようにその姿勢が上下反転する。これに伴い、図1に示すように、保持部材120内で後ローラ3側に位置した流動体131は、重力に従い図2に矢印にて示すように、堰111を乗り越え、後述の発電機構140を通過して、前ローラ2側へ流れる。以下に説明するが、当該コンベア用発電装置110は、保持部材120内を移動体130が移動することで発電機構140にて電力を発生させる構成であることから、移動体130に流動体131を用いることで、流動体131の自由落下を利用することができ、流動体量の調整を容易に行うことができ、それにより発電量の調節を容易に行うことができる。又、流動体131として水を用いれば、入手が容易である。又、流動体131として粉体や粒状体を用いた場合には、保持部材120が万一破損したときでも、液体の飛散はなく、エスカレータシステム200を構成する他の機器へ害が及ぶのを防ぐことができる。又、乾燥による重量低下や雑菌発生を回避することもできる。   The moving body 130 is provided in the holding member 120 and moves in the holding member 110 as the posture of the step 101 in the upper terminal gear 203 and the lower terminal gear 204 installed at both ends of the loop 202 is reversed upside down. . As described above, in the present embodiment, the moving body 130 is composed of the fluid 131 and uses, for example, a liquid, a powder, a granular body, or the like. As described above, as shown in FIG. 7, in the escalator system 200, when the step 101 reaches the upper terminal gear 203 and the lower terminal gear 204, the step 101 is changed from the state shown in FIG. As shown, the posture is inverted upside down. Accordingly, as shown in FIG. 1, the fluid 131 located on the rear roller 3 side in the holding member 120 moves over the weir 111 according to gravity as indicated by an arrow in FIG. 2, and generates a power generation mechanism 140 described later. And flows to the front roller 2 side. As will be described below, the power generation apparatus 110 for conveyors is configured to generate electric power by the power generation mechanism 140 when the moving body 130 moves in the holding member 120. By using, the free fall of the fluid 131 can be utilized, the amount of fluid can be adjusted easily, and the amount of power generation can be adjusted easily. Further, if water is used as the fluid 131, it is easy to obtain. In addition, when powder or granular material is used as the fluid 131, even if the holding member 120 is broken, there is no scattering of liquid, and other devices constituting the escalator system 200 are harmed. Can be prevented. In addition, weight loss and generation of germs due to drying can be avoided.

発電機構140は、上述のように、保持部材120内における移動体130の移動に応じて発電を行う部分であり、本実施形態では、回転部材141と、発電部142とを有する。図3に示すように、回転部材141は、保持部材120の軸方向における中央部分にて、保持部材120における周方向121へ回転可能な状態にて保持部材120内に設けられ、移動体130としての上記流動体131の流れに伴い周方向121へ回転する。このような回転部材141は、プロペラのような上記流動体131の流れに伴い回転力を発生する形状を有し、又、複数の永久磁石1411が回転部材141の周方向に沿って一定間隔にて配置されている。各磁石1411は、同形状にてなるが、隣接する磁石1411同士では、極性を異ならせている。よって、回転部材141の回転により交流磁界を発生させる。尚、符号1412を付した各矢印は、磁化方向を示している。   As described above, the power generation mechanism 140 is a part that generates power in accordance with the movement of the moving body 130 in the holding member 120, and includes the rotating member 141 and the power generation unit 142 in this embodiment. As shown in FIG. 3, the rotating member 141 is provided in the holding member 120 at a central portion in the axial direction of the holding member 120 so as to be rotatable in the circumferential direction 121 of the holding member 120. Rotate in the circumferential direction 121 with the flow of the fluid 131. Such a rotating member 141 has a shape that generates a rotational force with the flow of the fluid 131 such as a propeller, and a plurality of permanent magnets 1411 are arranged at regular intervals along the circumferential direction of the rotating member 141. Are arranged. Each magnet 1411 has the same shape, but the magnets 1411 adjacent to each other have different polarities. Therefore, an alternating magnetic field is generated by the rotation of the rotating member 141. In addition, each arrow which attached | subjected the code | symbol 1412 has shown the magnetization direction.

発電部142は、保持部材120の外側にて回転部材141に対向して設けられ、回転部材141の回転に従い電力を発生する。このような発電部142は、保持部材120の外面側に設けられた磁性体からなるコア1421と、該コア1421に巻回された導体1422とで形成されたコイル部1423を有し、複数のコイル部1423が上記周方向121に沿って等間隔にて配置される。各コイル部1423には、永久磁石を固定した回転部材141の回転により極性が交互に変化する交流磁界が作用する。又、上記磁界に垂直になるように導体1422がコア1421に巻回されていることから、上記交流磁界の作用により各コイル部1423は、交流電圧を発生する。   The power generation unit 142 is provided outside the holding member 120 so as to face the rotating member 141, and generates electric power according to the rotation of the rotating member 141. Such a power generation unit 142 includes a coil part 1423 formed of a core 1421 made of a magnetic material provided on the outer surface side of the holding member 120 and a conductor 1422 wound around the core 1421, and includes a plurality of coil parts 1423. Coil portions 1423 are arranged at equal intervals along the circumferential direction 121. An alternating magnetic field whose polarity changes alternately by the rotation of the rotating member 141 to which the permanent magnet is fixed acts on each coil portion 1423. Further, since the conductor 1422 is wound around the core 1421 so as to be perpendicular to the magnetic field, each coil portion 1423 generates an alternating voltage by the action of the alternating magnetic field.

本実施形態における踏段101は、上述の発電装置110に加えて、図3に示すように、発生した電力の充放電を行う充放電部160と、当該エスカレータシステム200の点検を行う点検装置170とを備える。尚、充放電部160及び点検装置170の設置、特に点検装置170の設置は、任意である。
上記充放電部160は、踏段101内に取り付けられ、発電部142に接続され発生した電力を充電するとともに、点検装置170に接続され、充電した電力を点検装置170に送る。発電部142にて発生する電圧は交流であり、充電する場合には直流化する必要がある。よって、充放電部160は、図6に示すように、全波整流回路161と、直流昇圧及び安定化回路162と、過充電防止回路163とを通過させて、バッテリ164に充電し、一方、バッテリ164からの放電を行うときに逆流を防止する逆流防止回路165も備える。
充放電部160を備えることで、外部からの給電手段を有することなく、踏段101自身にて電力供給が可能となり、又、装置構成をコンパクト化することができる。
In addition to the power generator 110 described above, the step 101 in the present embodiment includes a charging / discharging unit 160 that charges and discharges the generated power, and an inspection device 170 that checks the escalator system 200, as shown in FIG. Is provided. In addition, installation of the charging / discharging part 160 and the inspection apparatus 170, especially installation of the inspection apparatus 170 are arbitrary.
The charging / discharging unit 160 is attached in the step 101 and connected to the power generation unit 142 to charge the generated power, and is connected to the inspection device 170 to send the charged power to the inspection device 170. The voltage generated in the power generation unit 142 is an alternating current, and it is necessary to make it a direct current when charging. Therefore, as shown in FIG. 6, the charging / discharging unit 160 passes the full-wave rectifying circuit 161, the DC boosting and stabilizing circuit 162, and the overcharge prevention circuit 163 to charge the battery 164, A backflow prevention circuit 165 that prevents backflow when discharging from the battery 164 is also provided.
By providing the charging / discharging unit 160, it is possible to supply power by the step 101 itself without having an external power supply means, and the apparatus configuration can be made compact.

点検装置170は、既に提案されている公知の構成にてなり、各種センサを有し、該センサにて検出された踏段101の走行状態に関する情報に基づいて当該エスカレータシステム200の点検を行う装置であり、エスカレータシステム200に備わる上記受信装置221と交信可能な発信部を有する。   The inspection device 170 has a known configuration that has already been proposed, has various sensors, and inspects the escalator system 200 based on information on the running state of the step 101 detected by the sensors. There is a transmitter that can communicate with the receiver 221 provided in the escalator system 200.

このように構成される発電装置110は、以下のように動作する。
上述したようにエスカレータシステム200では、上部ターミナルギア203及び下部ターミナルギア204を両端部に設けて踏段101、201を無端状に連結してループ202を形成している。踏段101、201における乗客搭載面に乗客が搭乗可能な区間では、発電装置110を備えた踏段101は、乗客搭載面101aが水平状態を維持し、発電装置110も一定の傾斜状態を維持する。よって、発電装置110の保持部材120内の流動体131も移動せず一定の状態が維持される。従って、発電装置110が発電することはない。よって、発電装置110から不要な振動や騒音が発生することはない。
The power generator 110 configured as described above operates as follows.
As described above, in the escalator system 200, the upper terminal gear 203 and the lower terminal gear 204 are provided at both ends, and the steps 101 and 201 are connected endlessly to form the loop 202. In a section in which passengers can board the passenger mounting surfaces of the steps 101 and 201, the step 101 including the power generation device 110 maintains the horizontal state of the passenger mounting surface 101a and the power generation device 110 also maintains a constant inclination state. Therefore, the fluid 131 in the holding member 120 of the power generation apparatus 110 does not move, and a constant state is maintained. Therefore, the power generator 110 does not generate power. Therefore, unnecessary vibration and noise are not generated from the power generation device 110.

一方、踏段101が上部ターミナルギア203及び下部ターミナルギア204に到達することで、踏段101は、図7に示すようにその姿勢が上下反転する。これに伴い、発電装置110の傾斜状態が変化し、保持部材120内の流動体131が保持部材120の一端から他端へ移動する。該移動により、回転部材141が回転駆動され、回転部材141の回転に応じて発電部142から電力が発生する。発生した電力は、充放電部160のバッテリ164に充電される。   On the other hand, when the step 101 reaches the upper terminal gear 203 and the lower terminal gear 204, the posture of the step 101 is reversed upside down as shown in FIG. Along with this, the inclined state of the power generation device 110 changes, and the fluid 131 in the holding member 120 moves from one end to the other end of the holding member 120. By this movement, the rotating member 141 is rotationally driven, and electric power is generated from the power generation unit 142 according to the rotation of the rotating member 141. The generated power is charged in the battery 164 of the charging / discharging unit 160.

このように発電装置110によれば、発電動作は、踏段101の姿勢が変化する上部ターミナルギア203及び下部ターミナルギア204部分を通過するときのみであり、乗客が搭乗可能な区間では、発電動作に伴う振動及び騒音の発生は防止でき、乗客に不快感を与えることはない。又、エスカレータシステム200の点検装置170が踏段101に備わる場合でも、発電動作に伴う振動及び騒音の発生を防止できることから、従来のように発電動作に伴う振動及び騒音が点検装置170によるレールの点検等のためのデータ収集に悪影響を与えるということはなく、高精度にて点検を行うことができる。   As described above, according to the power generation device 110, the power generation operation is performed only when passing through the upper terminal gear 203 and the lower terminal gear 204 where the posture of the step 101 changes. The accompanying vibration and noise can be prevented and passengers will not be uncomfortable. In addition, even when the inspection device 170 of the escalator system 200 is provided in the step 101, the generation of vibration and noise associated with the power generation operation can be prevented. Therefore, it is possible to perform inspection with high accuracy without adversely affecting data collection.

実施の形態2.
上述の実施形態では、発電装置110に備わる移動体130は流動体131であり、発電機構140として回転部材141と、コイル部1423を有する発電部142とを備える構成であったが、該形態に限定するものではなく、以下の示すような各種の変形例を採ることができる。
当該実施の形態2では、踏段101に備わる発電装置115は、図4に示すように、移動体130として、円柱状で棒状であり、保持部材120の軸方向に沿う磁化方向1412を有する永久磁石132を用いる。又、発電機構140は、保持部材120の軸方向の中央部分で、保持部材120の外周面にその周方向に沿って導体1422を巻回したコイル1431を有する発電部143を用いる。
Embodiment 2. FIG.
In the above-described embodiment, the moving body 130 included in the power generation apparatus 110 is the fluid 131, and the power generation mechanism 140 includes the rotating member 141 and the power generation unit 142 including the coil unit 1423. The present invention is not limited, and various modifications as shown below can be adopted.
In the second embodiment, as shown in FIG. 4, the power generation device 115 provided in the step 101 is a permanent magnet having a cylindrical shape and a rod shape as the moving body 130 and having a magnetization direction 1412 along the axial direction of the holding member 120. 132 is used. Further, the power generation mechanism 140 uses a power generation unit 143 having a coil 1431 in which a conductor 1422 is wound around the outer peripheral surface of the holding member 120 along the circumferential direction at the central portion of the holding member 120 in the axial direction.

このような構成を採ることで、踏段101が上部ターミナルギア203及び下部ターミナルギア204部分を通過するときには踏段101の姿勢が変化し、これに伴い、保持部材120内の永久磁石132が保持部材120の一端から他端へ移動する。永久磁石132の移動に伴い、保持部材120の周面に形成したコイル1431では磁束変化が発生し、発電部143は発電を行う。発生した電力は、充放電部160のバッテリ164に充電される。   By adopting such a configuration, when the step 101 passes through the upper terminal gear 203 and the lower terminal gear 204, the posture of the step 101 changes, and accordingly, the permanent magnet 132 in the holding member 120 is moved to the holding member 120. Move from one end to the other. As the permanent magnet 132 moves, a change in magnetic flux occurs in the coil 1431 formed on the peripheral surface of the holding member 120, and the power generation unit 143 generates power. The generated power is charged in the battery 164 of the charging / discharging unit 160.

上述の実施の形態2の構成による発電装置115でも、実施の形態1の場合と同じ効果を得ることができる。さらに、実施の形態2では、保持部材120内に、回転部材141のような回転体を設ける必要がないことから、装置構成を単純化することができコスト削減に寄与でき、かつ回転体を回転させるための摺動部分が無く、高い装置信頼性を得ることができる。又、保持部材120が破損した場合であっても、移動体130が拡散することはない。   The same effect as that of the first embodiment can be obtained also by the power generation device 115 having the configuration of the second embodiment described above. Furthermore, in the second embodiment, since it is not necessary to provide a rotating body such as the rotating member 141 in the holding member 120, the apparatus configuration can be simplified and the cost can be reduced, and the rotating body can be rotated. There is no sliding part for making it possible to obtain high device reliability. Even when the holding member 120 is damaged, the moving body 130 does not diffuse.

さらに又、実施の形態2の構成の変形例として、図5に示す発電装置116の構成を採ることもできる。図5に示すように、移動体130として、角柱状で棒状であり、磁化方向1412にて示すように磁力線を保持部材120の軸方向に直交する方向に磁化した永久磁石133を用いる。又、発電機構140は、保持部材120の軸方向の中央部分で、保持部材120の外側面に、磁性体からなるコア1441と、磁化方向1412に垂直になるようにコア1441に巻回した導体1442とで形成したコイル部1443を有する発電部144を用いる。尚、図5では、保持部材120が角パイプ状の形態を示すが、図4に示すように円筒形状にて構成することもできる。このとき永久磁石133の形状は、円筒状の保持部材120に合わせて円柱状となる。   Furthermore, as a modification of the configuration of the second embodiment, the configuration of the power generation device 116 shown in FIG. 5 can be adopted. As shown in FIG. 5, a permanent magnet 133 is used as the moving body 130, which is prismatic and rod-shaped and magnetized in the direction perpendicular to the axial direction of the holding member 120 as indicated by the magnetization direction 1412. The power generation mechanism 140 includes a core 1441 made of a magnetic material on the outer surface of the holding member 120 and a conductor wound around the core 1441 so as to be perpendicular to the magnetization direction 1412 at the central portion of the holding member 120 in the axial direction. The power generation unit 144 having the coil unit 1443 formed by the configuration 1442 is used. In addition, in FIG. 5, although the holding member 120 shows the form of a square pipe shape, as shown in FIG. 4, it can also comprise in a cylindrical shape. At this time, the shape of the permanent magnet 133 becomes a columnar shape in accordance with the cylindrical holding member 120.

このように構成した上記変形例においても、踏段101の姿勢変化に伴い、保持部材120内の永久磁石133が保持部材120の一端から他端へ移動する。永久磁石133の移動に伴い、保持部材120の側面に配置したコイル部1443では磁束変化が発生し、発電部144は発電を行う。発生した電力は、充放電部160のバッテリ164に充電される。
このように構成される上記変形例においても、実施の形態2の場合と同じ効果を得ることができる。
又、図4及び図5に示す発電装置115、116を備えた踏段101には、充放電部160に加えて、図3に示すように、当該エスカレータシステム200の点検を行う点検装置170をさらに備えることもできる。
Also in the modified example configured as described above, the permanent magnet 133 in the holding member 120 moves from one end of the holding member 120 to the other end with a change in the posture of the step 101. Along with the movement of the permanent magnet 133, a magnetic flux change occurs in the coil portion 1443 arranged on the side surface of the holding member 120, and the power generation portion 144 generates power. The generated power is charged in the battery 164 of the charging / discharging unit 160.
Also in the modified example configured as described above, the same effect as that of the second embodiment can be obtained.
Further, in addition to the charging / discharging unit 160, the step 101 provided with the power generation devices 115 and 116 shown in FIGS. 4 and 5 is further provided with an inspection device 170 for inspecting the escalator system 200 as shown in FIG. It can also be provided.
