　次に、図３から図７を用いて、移動手摺１の抗張体２の検査方法を説明する。
　図３から図７は実施の形態１における乗客コンベアの手摺抗張体検査装置の縦断面図である。 Next, a method of inspecting the tensile body 2 of the moving handrail 1 will be described with reference to FIGS. 3 to 7.
3 to 7 are vertical sectional views of the handrail tensile body inspection device for the passenger conveyor according to the first embodiment.
　図３において、矢印Ａは、抗張体２の磁化の向きを示す。矢印Ｂは、一対の着磁器側磁石６ａが発生させる磁界の向きを示す。矢印Ｃは、磁気センサ側磁石７ｂが発生させる磁界の向きを示す。磁気センサ側磁石７ｂの磁界は、正常な抗張体２に影響しないように調整される。 In FIG. 3, the arrow A indicates the direction of magnetization of the tensile body 2. The arrow B indicates the direction of the magnetic field generated by the pair of magnetizer-side magnets 6a. The arrow C indicates the direction of the magnetic field generated by the magnetic sensor side magnet 7b. The magnetic field of the magnetic sensor side magnet 7b is adjusted so as not to affect the normal tensile body 2.
　手摺抗張体検査装置３よりも左側において、抗張体２は、着磁されない。このため、抗張体２の内部において、切れた素線２ａを含め、磁化の向きは不均一である。 On the left side of the handrail tensile body inspection device 3, the tensile body 2 is not magnetized. Therefore, inside the tensile body 2, the magnetization direction is non-uniform, including the broken wires 2a.
　図４に示されるように、手摺抗張体検査装置３が左側に移動した際、切れた素線２ａは、一対の着磁器側磁石６ａの一方の磁界により右方向に着磁される。その結果、切れた素線２ａの磁化の向きが揃う。 As shown in FIG. 4, when the handrail tensile body inspection device 3 moves to the left, the broken wire 2a is magnetized rightward by the magnetic field of one of the pair of magnetizer side magnets 6a. As a result, the magnetization directions of the broken wires 2a are aligned.
　図５に示されるように、手摺抗張体検査装置３がさらに左側に移動した際、切れた素線２ａの磁化の向きは、揃った状態を維持する。 As shown in FIG. 5, when the handrail tensile body inspection device 3 is further moved to the left side, the magnetization directions of the broken wires 2a are maintained in a uniform state.
　図６に示されるように、手摺抗張体検査装置３がさらに左側に移動した際、切れた素線２ａは、磁気センサ側磁石７ｂの磁界により反転する。この際、検出素子７ａは、磁界の変動を検出する。 As shown in FIG. 6, when the handrail tensile body inspection device 3 further moves to the left, the broken wire 2a is reversed by the magnetic field of the magnetic sensor side magnet 7b. At this time, the detection element 7a detects the fluctuation of the magnetic field.
　図７に示されるように、手摺抗張体検査装置３がさらに左側に移動した際、切れた素線２ａは、磁気センサ側磁石７ｂの磁界により再び反転する。この際、検出素子７ａは、磁界の変動を検出する。 As shown in FIG. 7, when the handrail tensile body inspection device 3 further moves to the left, the broken wire 2a is inverted again by the magnetic field of the magnetic sensor side magnet 7b. At this time, the detection element 7a detects the fluctuation of the magnetic field.
　図示されないが、検出素子７ａの検出結果の情報は、外部装置１１に記憶される。当該情報は、必要に応じて外部装置１１に表示される。 Although not shown, the information of the detection result of the detection element 7a is stored in the external device 11. The information is displayed on the external device 11 as needed.
　なお、手摺抗張体検査装置３が右側に移動した際、切れた素線２ａは、一対の着磁器側磁石６ａの他方の磁界により左方向に着磁される。その結果、切れた素線２ａの磁化の向きが揃う。その後、検出素子７ａは、手摺抗張体検査装置３が右側に移動した際と同様に磁界の変動を検出する。 When the handrail tensile body inspection device 3 moves to the right, the broken wire 2a is magnetized leftward by the magnetic field of the other of the pair of magnetizer side magnets 6a. As a result, the magnetization directions of the broken wires 2a are aligned. After that, the detection element 7a detects the fluctuation of the magnetic field in the same manner as when the handrail tensile body inspection device 3 moves to the right.
　以上で説明した実施の形態１によれば、磁気センサ７は、着磁器６により着磁された素線２ａを着磁器６による着磁の方向とは反対方向に着磁し、磁界の変動を検出する。この際の磁界の変動は大きい。このため、抗張体２において素線２ａが切れていることをより確実に検出することができる。 According to the first embodiment described above, the magnetic sensor 7 magnetizes the element wire 2a magnetized by the magnetizer 6 in the direction opposite to the direction of magnetization by the magnetizer 6 to prevent fluctuations in the magnetic field. To detect. The fluctuation of the magnetic field at this time is large. Therefore, it is possible to more reliably detect that the strand 2a is broken in the tensile body 2.
　なお、一対の着磁器６のうちの１つだけを設けてもよい。この場合も、手摺抗張体検査装置３の向きと移動方向とを正しく設定すれば、抗張体２において素線２ａが切れていることをより確実に検出することができる。 Note that only one of the pair of magnetizers 6 may be provided. Also in this case, if the direction and the moving direction of the handrail tensile body inspection device 3 are set correctly, it is possible to more reliably detect that the strand 2a of the tensile body 2 is broken.
　これに対し、実施の形態１のように、一対の着磁器６を設ければ、手摺抗張体検査装置３の向きと移動方向とを気にせずに、抗張体２において素線２ａが切れていることをより確実に検出することができる。 On the other hand, if the pair of magnetizers 6 are provided as in the first embodiment, the strands 2a of the tensile body 2 are removed without worrying about the direction and the moving direction of the handrail tensile body inspection device 3. The disconnection can be detected more reliably.
　なお、装置内の全磁石のＮ極とＳ極を入れ替えてもよい。 Note that the N and S poles of all magnets in the device may be replaced.
　次に、図８を用いて、磁気センサ７の第１変形例を説明する。
　図８は実施の形態１における乗客コンベアの手摺抗張体検査装置に用いられる磁気センサの第１変形例の縦断面図である。 Next, a first modification of the magnetic sensor 7 will be described with reference to FIG.
FIG. 8 is a vertical cross-sectional view of a first modified example of the magnetic sensor used in the handrail tensile body inspection device for the passenger conveyor according to the first embodiment.
　図８に示されるように、磁気センサ７は、検出素子７ａと一対の磁気センサ側磁石７ｂとを備える。 As shown in FIG. 8, the magnetic sensor 7 includes a detection element 7a and a pair of magnetic sensor side magnets 7b.
　検出素子７ａは、磁界を検出し得るように設けられる。 The detection element 7a is provided so as to detect a magnetic field.
　一対の磁気センサ側磁石７ｂの一方は、検出素子７ａの一側の上方に設けられる。一対の磁気センサ側磁石７ｂの一方において、Ｓ極の端部は、上方を向くように配置される。Ｎ極の端部は、下方を向くように配置される。 One of the pair of magnetic sensor side magnets 7b is provided above one side of the detection element 7a. In one of the pair of magnetic sensor side magnets 7b, the end portion of the S pole is arranged so as to face upward. The end of the N pole is arranged so as to face downward.
　一対の磁気センサ側磁石７ｂの他方は、検出素子７ａの他側の上方に設けられる。一対の磁気センサ側磁石７ｂの他方は、移動手摺１の長手方向に一対の磁気センサ側磁石７ｂの一方と並んで設けられる。一対の磁気センサ側磁石７ｂの他方において、Ｓ極の端部は、上方を向くように配置される。Ｎ極の端部は、下方を向くように配置される。 The other of the pair of magnetic sensor side magnets 7b is provided above the other side of the detection element 7a. The other of the pair of magnetic sensor side magnets 7b is provided side by side with one of the pair of magnetic sensor side magnets 7b in the longitudinal direction of the moving handrail 1. The other end of the pair of magnetic sensor side magnets 7b is arranged so that the end of the S pole faces upward. The end of the N pole is arranged so as to face downward.
　この場合、磁気センサ７の直下において、磁力がより遠方に届きやすくなる。このため、移動手摺１の奥まった箇所にある切れた素線２ａに対しても、磁力を加えることができる。その結果、抗張体２において素線２ａが切れていることをより確実に検出することができる。 In this case, the magnetic force is more likely to reach farther below the magnetic sensor 7. Therefore, the magnetic force can be applied to the broken wire 2a in the recessed part of the moving handrail 1. As a result, it is possible to more reliably detect that the strand 2a is broken in the tensile body 2.
　次に、図９を用いて、磁気センサ７の第２変形例を説明する。
　図９は実施の形態１における乗客コンベアの手摺抗張体検査装置に用いられる磁気センサの第２変形例の縦断面図である。 Next, a second modification of the magnetic sensor 7 will be described with reference to FIG.
FIG. 9 is a vertical cross-sectional view of a second modified example of the magnetic sensor used in the handrail tensile body inspection device for the passenger conveyor according to the first embodiment.
　図９に示されるように、磁気センサ７は、検出素子７ａと一対の磁気センサ側磁石７ｂとを備える。 As shown in FIG. 9, the magnetic sensor 7 includes a detection element 7a and a pair of magnetic sensor side magnets 7b.
　検出素子７ａは、磁界を検出し得るように設けられる。 The detection element 7a is provided so as to detect a magnetic field.
　一対の磁気センサ側磁石７ｂの一方は、検出素子７ａの一側から移動手摺１の長手方向に離れた位置において検出素子７ａよりも上方に設けられる。磁気センサ側磁石７ｂにおいて、Ｎ極の端部は、上方を向くように配置される。Ｓ極の端部は、下方を向くように配置される。 One of the pair of magnetic sensor side magnets 7b is provided above the detection element 7a at a position separated from one side of the detection element 7a in the longitudinal direction of the moving handrail 1. In the magnet 7b on the magnetic sensor side, the end of the N pole is arranged so as to face upward. The end of the south pole is arranged so as to face downward.
　一対の磁気センサ側磁石７ｂの他方は、検出素子７ａの他側から移動手摺１の長手方向に離れた位置において検出素子７ａよりも上方に設けられる。一対の磁気センサ側磁石７ｂの他方は、移動手摺１の長手方向に一対の磁気センサ側磁石７ｂの一方と並んで設けられる。磁気センサ側磁石７ｂにおいて、Ｓ極の端部は、上方を向くように配置される。Ｎ極の端部は、下方を向くように配置される。 The other of the pair of magnetic sensor side magnets 7b is provided above the detection element 7a at a position apart from the other side of the detection element 7a in the longitudinal direction of the moving handrail 1. The other of the pair of magnetic sensor side magnets 7b is provided side by side with one of the pair of magnetic sensor side magnets 7b in the longitudinal direction of the moving handrail 1. In the magnetic sensor side magnet 7b, the end portion of the S pole is arranged so as to face upward. The end of the N pole is arranged so as to face downward.
　この場合、磁気センサ７の直下において、磁力がより遠方に届きやすくなる。このため、移動手摺１の奥まった箇所にある切れた素線２ａに対しても、磁力を加えることができる。その結果、抗張体２において素線２ａが切れていることをより確実に検出することができる。 In this case, the magnetic force is more likely to reach farther below the magnetic sensor 7. Therefore, the magnetic force can be applied to the broken wire 2a in the recessed part of the moving handrail 1. As a result, it is possible to more reliably detect that the strand 2a is broken in the tensile body 2.
実施の形態２．

Therefore, each of the pair of magnetizer-side magnets 6a can be easily manufactured.
　ただし、一対の着磁器側磁石６ａの各々において、外側へ向かう外側磁界が増加する。このため、抗張体２と素線２ａとの保磁力が外側磁界よりも大きい場合に実施の形態２の手摺抗張体検査装置３を適用することができる。 However, in each of the pair of magnetizer side magnets 6a, the outer magnetic field toward the outside increases. Therefore, when the coercive force between the tensile body 2 and the strand 2a is larger than the outer magnetic field, the handrail tensile body inspection device 3 according to the second embodiment can be applied.

Therefore, each of the pair of magnetizer-side magnets 6a can be manufactured more easily.

　図１４は実施の形態４における乗客コンベアの手摺抗張体検査装置の縦断面図である。なお、実施の形態１の部分と同一又は相当部分には同一符号が付される。当該部分の説明は省略される。 Fourth Embodiment
FIG. 14 is a vertical sectional view of a handrail tensile body inspection device for a passenger conveyor according to the fourth embodiment. The same or corresponding parts as those of the first embodiment are denoted by the same reference numerals. The description of this part is omitted.

The magnetic sensor 7 is arranged between the S pole and the N pole of the magnetizer 6.
　以上で説明した実施の形態４によれば、着磁器６は、１つだけでよい。このため、簡単な構成で、抗張体２において素線２ａが切れていることをより確実に検出することができる。 According to the fourth embodiment described above, only one magnetizer 6 is required. Therefore, it is possible to more reliably detect that the strand 2a is broken in the tensile body 2 with a simple configuration.
　また、着磁器６の磁力が抗張体２に印加される時間が実施の形態１から実施の形態３よりも長い。このため、保磁力が小さい抗張体２に対しても磁化の向きを一定にすることができる。 Also, the time for which the magnetic force of the magnetizer 6 is applied to the tensile body 2 is longer than in the first to third embodiments. Therefore, the direction of magnetization can be made constant even for the tensile body 2 having a small coercive force.
　なお、実施の形態１から実施の形態４において、複数の抗張体２のそれぞれに対向するように複数の検出素子７ａを設けてもよい。この場合、複数の抗張体２のうちのいずれの抗張体２において素線２ａが切れているのかを判別することができる。 In addition, in the first to fourth embodiments, a plurality of detection elements 7a may be provided so as to face each of the plurality of tensile bodies 2. In this case, it is possible to determine in which of the plurality of tensile bodies 2 the strand 2a is broken.
　また、実施の形態１から実施の形態４において、手摺抗張体検査装置３を固定し、移動手摺１を移動させてもよい。この場合も、抗張体２において素線２ａが切れていることをより確実に検出することができる。 Further, in the first to fourth embodiments, the handrail tensile body inspection device 3 may be fixed and the moving handrail 1 may be moved. Also in this case, it is possible to more reliably detect that the strand 2a is broken in the tensile body 2.
　また、実施の形態１から実施の形態４において、乗客コンベアの上部または下部において、移動手摺１の湾曲部を検査してもよい。この場合、移動手摺１のがたつきが抑えられた状態で容易に検査を行うことができる。 In addition, in the first to fourth embodiments, the curved portion of the moving handrail 1 may be inspected at the upper part or the lower part of the passenger conveyor. In this case, the inspection can be easily performed with the rattling of the moving handrail 1 suppressed.
　また、実施の形態１から実施の形態４において、鉄、電磁鋼板、パーマロイ等の軟磁性体と磁石とで一対の着磁器６の各々とを構成してもよい。 Further, in the first to fourth embodiments, each of the pair of magnetizers 6 may be configured by a magnet and a soft magnetic material such as iron, electromagnetic steel sheet, permalloy or the like.
　また、実施の形態１から実施の形態４において、電磁石で一対の着磁器６の各々を構成してもよい。 In addition, in the first to fourth embodiments, each of the pair of magnetizers 6 may be composed of an electromagnet.
　また、実施の形態１から実施の形態４の一対の着磁器側磁石６ａと磁気センサ側磁石７ｂとにおいて、Ｓ極とＮ極とを反転させてもよい。 Further, in the pair of magnetizer side magnets 6a and magnetic sensor side magnets 7b of Embodiments 1 to 4, the S pole and the N pole may be reversed.
　また、実施の形態１から実施の形態４の手摺抗張体検査装置３を乗客コンベアの内部に設置してもよい。この場合、作業員による作業を不要とすることができる。 Further, the handrail tensile body inspection device 3 of the first to fourth embodiments may be installed inside the passenger conveyor. In this case, the work by the worker can be eliminated.
