Support 12 supports detector 13 , marking device 14 , marking device 15 and control device 16 .
　検出器１３に、特定の検出領域が設けられる。本実施の形態に示す例では、検出器１３に、断面がＵ字形状の溝１３ａが形成される。溝１３ａの内側の空間は上記検出領域である。検出器１３は、ロープ４のうちこの検出領域に配置された部分に破断部４ｃが存在することを検出する。検出器１３は、どのような方法で破断部４ｃの存在を検出しても良い。一例として、検出器１３は、漏洩磁束法を利用して破断部４ｃの存在を検出する。 The detector 13 is provided with a specific detection area. In the example shown in this embodiment, the detector 13 is formed with a groove 13a having a U-shaped cross section. The space inside the groove 13a is the detection area. The detector 13 detects that the broken portion 4c exists in the portion of the rope 4 located in this detection area. Detector 13 may detect the presence of break 4c by any method. As an example, detector 13 detects the presence of break 4c using the leakage flux method.
　図１は、ロープ４のうち巻上機５から下方に延びる部分が検出器１３の検出領域に配置される好適な例を示す。図１に示す例であれば、ロープ４の中でも曲げられる頻度が特に高い部分の検査を行うことができる。 FIG. 1 shows a preferred example in which the part of the rope 4 extending downward from the hoisting machine 5 is arranged in the detection area of the detector 13 . In the example shown in FIG. 1, it is possible to inspect a portion of the rope 4 that is particularly frequently bent.
　マーキング装置１４及びマーキング装置１５は、ロープ４にマーキング処理を行うための装置である。ロープ４に対するマーキング処理は、どのような方法で行われても良い。一例として、マーキング処理は、ロープ４に対して塗料を吹き付けることによって行われる。他の例として、マーキング処理は、ペン或いは筆等によってインクをロープ４に塗ることによって行われても良い。 The marking device 14 and the marking device 15 are devices for marking the rope 4. Any method may be used to mark the rope 4 . As an example, the marking process is performed by spraying the rope 4 with paint. Alternatively, the marking process may be performed by applying ink to the rope 4 with a pen or brush or the like.
　検出器１３は、マーキング装置１４とマーキング装置１５との間に配置される。即ち、マーキング装置１４及びマーキング装置１５により、ロープ４のうち検出領域に入る直前の部分と検出領域から出た直後の部分とに対してマーキング処理を行うことができる。マーキング装置１４は、ロープ４のうち検出領域から延びる一方の部分にマーキング処理を行うための装置である。マーキング装置１５は、ロープ４のうち検出領域から延びるもう一方の部分にマーキング処理を行うための装置である。 The detector 13 is arranged between the marking device 14 and the marking device 15 . That is, the marking device 14 and the marking device 15 can mark a portion of the rope 4 immediately before entering the detection area and a portion immediately after exiting the detection area. The marking device 14 is a device for marking one portion of the rope 4 extending from the detection area. The marking device 15 is a device for marking the other portion of the rope 4 extending from the detection area.
　上述したように、本実施の形態に示す例では、ロープ４のうち巻上機５から下方に延びる部分が検出器１３の検出領域に配置される。例えば、マーキング装置１４は検出器１３の上に配置される。即ち、マーキング装置１４は、ロープ４のうち検出領域から上方に延びる部分にマーキング処理を行うことができるように配置される。マーキング装置１５は検出器１３の下に配置される。即ち、マーキング装置１５は、ロープ４のうち検出領域から下方に延びる部分にマーキング処理を行うことができるように配置される。 As described above, in the example shown in this embodiment, the portion of the rope 4 extending downward from the hoisting machine 5 is arranged in the detection area of the detector 13 . For example, marking device 14 is positioned above detector 13 . That is, the marking device 14 is arranged so as to be able to perform the marking process on the part of the rope 4 that extends upward from the detection area. A marking device 15 is arranged below the detector 13 . That is, the marking device 15 is arranged so as to be able to perform the marking process on the part of the rope 4 that extends downward from the detection area.
　制御装置１６は、検出器１３の検出結果に応じて、マーキング装置１４とマーキング装置１５とを制御する。例えば、制御装置１６は、判定部２１、及び制御部２２を備える。 The control device 16 controls the marking device 14 and the marking device 15 according to the detection result of the detector 13. For example, the control device 16 includes a determination section 21 and a control section 22 .
　図５は、検査装置１１の動作例を示すフローチャートである。図６は、検査装置１１の機能を説明するための図である。図６は、図２に相当する図である。 FIG. 5 is a flowchart showing an operation example of the inspection device 11. FIG. FIG. 6 is a diagram for explaining the functions of the inspection device 11. As shown in FIG. FIG. 6 is a diagram corresponding to FIG.
　例えば、保守員は、図１に示すように検査装置１１を昇降路３の頂部に設置すると、かご１を最上階の乗場から最下階の乗場に向けて移動させる。これにより、検査装置１１に対してロープ４が下方に移動する。かご１が最上階の乗場から最下階の乗場に移動する間に破断部４ｃが検出領域を通過すると、破断部４ｃの存在が検出器１３によって検出される。 For example, maintenance personnel install the inspection device 11 at the top of the hoistway 3 as shown in FIG. 1, and then move the car 1 from the top floor landing to the bottom floor landing. Thereby, the rope 4 moves downward with respect to the inspection device 11 . When the broken portion 4c passes through the detection area while the car 1 is moving from the landing on the top floor to the landing on the lowest floor, the presence of the broken portion 4c is detected by the detector 13 .
　制御装置１６では、判定部２１が、破断部４ｃが存在するか否かを判定する（Ｓ１０１）。検出器１３によって破断部４ｃの存在が検出されなければ、Ｓ１０１でＮｏと判定される。検出器１３によって破断部４ｃの存在が検出されると、Ｓ１０１でＹｅｓと判定される。 In the control device 16, the determination unit 21 determines whether or not the fractured portion 4c exists (S101). If the presence of the broken portion 4c is not detected by the detector 13, it is determined as No in S101. When the detector 13 detects the presence of the broken portion 4c, the determination in S101 is Yes.
　図６（ａ）は、破断部４ｃが検出領域に配置された状態を示す。即ち、図６（ａ）に示す状態では、Ｓ１０１でＹｅｓと判定される。Ｓ１０１でＹｅｓと判定されると、制御部２２は、マーキング装置１４とマーキング装置１５との双方にマーキング処理を行わせる（Ｓ１０２）。例えば、Ｓ１０２では、ロープ４のうち検出領域の直上に配置された部分に対してマーキング装置１４から塗料が吹き付けられる。同時に、ロープ４のうち検出領域の直下に配置された部分に対してマーキング装置１５から塗料が吹き付けられる。 FIG. 6(a) shows a state in which the breaking portion 4c is arranged in the detection area. That is, in the state shown in FIG. 6A, it is determined as Yes in S101. If determined as Yes in S101, the control unit 22 causes both the marking device 14 and the marking device 15 to perform the marking process (S102). For example, in S<b>102 , paint is sprayed from the marking device 14 onto the part of the rope 4 that is positioned directly above the detection area. At the same time, paint is sprayed from the marking device 15 onto the portion of the rope 4 that is located directly below the detection area.
　その後のかご１の移動に伴い、破断部４ｃは検出領域を通過し、更に下方に移動する。図６（ｂ）は、破断部４ｃが検出領域の下方に移動した状態を示す。図６（ｂ）に示すように、破断部４ｃは、マーキング装置１４によって付された印１４ａとマーキング装置１５によって付された印１５ａとの間に存在する。 With the subsequent movement of the car 1, the broken portion 4c passes through the detection area and moves further downward. FIG. 6(b) shows a state in which the breaking portion 4c has moved below the detection area. As shown in FIG. 6(b), the fracture portion 4c exists between the mark 14a made by the marking device 14 and the mark 15a made by the marking device 15. As shown in FIG.
　本実施の形態に示す例では、検出器１３は、マーキング装置１４とマーキング装置１５との間に配置されている。このため、マーキング装置１４とマーキング装置１５とにより、ロープ４のうち検出領域に入る直前の部分と検出領域から出た直後の部分との双方に対してマーキング処理を行うことができる。本実施の形態に示す例であれば、検査装置１１に可動部等を備える必要がなく、構造の簡素化が可能である。また、本実施の形態に示す例であれば、破断部４ｃに対して適切な位置にマーキングを行うことができる。 In the example shown in this embodiment, the detector 13 is arranged between the marking device 14 and the marking device 15 . Therefore, the marking device 14 and the marking device 15 can mark both the portion of the rope 4 immediately before entering the detection area and the portion immediately after exiting the detection area. In the example shown in this embodiment, there is no need to equip the inspection apparatus 11 with a movable part or the like, and the structure can be simplified. Further, in the example shown in the present embodiment, marking can be performed at an appropriate position with respect to the breaking portion 4c.
　上述した例では、破断部４ｃの存在が検出されると、マーキング装置１４とマーキング装置１５との双方が同時にマーキング処理を行う。保守員は、かご１を最下階の乗場に停止させた後に、ロープ４のうち、マーキング装置１４によって付された印１４ａとマーキング装置１５によって付された印１５ａとの間に配置された部分を調べれば良い。このため、ロープ４の検査に必要な時間と手間とを軽減できる。また、本実施の形態に示す例であれば、ロープ４の移動方向に関わらず、上述した効果を奏することが可能である。 In the example described above, when the presence of the broken portion 4c is detected, both the marking device 14 and the marking device 15 perform marking processing at the same time. After stopping the car 1 at the landing on the lowest floor, the maintenance personnel removes the portion of the rope 4 placed between the mark 14a marked by the marking device 14 and the mark 15a marked by the marking device 15. should be investigated. Therefore, the time and effort required for inspecting the rope 4 can be reduced. Further, in the example shown in the present embodiment, the effects described above can be obtained regardless of the moving direction of the rope 4 .
　以下に、検査装置１１が採用可能な他の機能について説明する。 Other functions that can be adopted by the inspection device 11 will be described below.
　制御装置１６は、図４に示すように、方向検出部２３を更に備えても良い。方向検出部２３は、ロープ４が移動する方向を検出する。方向検出部２３は、どのような方法によってロープ４の移動方向を検出しても良い。一例として、検査装置１１は、利用者が手動で情報を入力するための入力装置１７を備える。かかる場合、方向検出部２３は、入力装置１７から入力された情報に基づいて、ロープ４が移動する方向を検出する。 The control device 16 may further include a direction detection section 23, as shown in FIG. The direction detector 23 detects the direction in which the rope 4 moves. The direction detection unit 23 may detect the moving direction of the rope 4 by any method. As an example, the inspection device 11 includes an input device 17 for manually inputting information by the user. In this case, the direction detection unit 23 detects the direction in which the rope 4 moves based on the information input from the input device 17 .
　第１釦及び第２釦（図示せず）が入力装置１７として検査装置１１に備えられる場合、方向検出部２３は、第１釦が押されていればロープ４の移動方向が第１方向であると検出する。第１方向は、ロープ４のうちマーキング装置１５に対向する部分が検出領域に近づく方向である。本実施の形態に示す例であれば、かご１が上方に移動すると、ロープ４は第１方向に移動する。 When the inspection device 11 is provided with a first button and a second button (not shown) as the input device 17, the direction detection unit 23 detects that the moving direction of the rope 4 is the first direction if the first button is pressed. Detect if there is. The first direction is the direction in which the portion of the rope 4 facing the marking device 15 approaches the detection area. In the example shown in this embodiment, when the car 1 moves upward, the rope 4 moves in the first direction.
　方向検出部２３は、第２釦が押されていればロープ４の移動方向が第２方向であると検出する。第２方向は、ロープ４のうちマーキング装置１４に対向する部分が検出領域に近づく方向である。即ち、第２方向は、第１方向とは逆の方向である。本実施の形態に示す例であれば、かご１が下方に移動すると、ロープ４は第２方向に移動する。 The direction detection unit 23 detects that the moving direction of the rope 4 is the second direction if the second button is pressed. The second direction is the direction in which the portion of the rope 4 facing the marking device 14 approaches the detection area. That is, the second direction is a direction opposite to the first direction. In the example shown in this embodiment, when the car 1 moves downward, the rope 4 moves in the second direction.
　他の例として、検査装置１１は、ロープ４に接触するローラ１８を備えても良い。図７は、検査装置１１の他の例を示す図である。図７は、ローラ１８が検出器１３に内蔵されている例を示す。図７に示す例では、方向検出部２３は、ローラ１８が回転する方向に基づいて、ロープ４が移動する方向を検出する。 As another example, the inspection device 11 may include a roller 18 that contacts the rope 4. FIG. 7 is a diagram showing another example of the inspection device 11. As shown in FIG. FIG. 7 shows an example in which roller 18 is built into detector 13 . In the example shown in FIG. 7, the direction detection unit 23 detects the direction in which the rope 4 moves based on the direction in which the roller 18 rotates.
　図８は、検査装置１１の他の動作例を示すフローチャートである。制御装置１６が方向検出部２３を備える場合、制御装置１６では、ロープ４の移動方向が判定される。例えば、ロープ４が第１方向に移動していることが方向検出部２３によって検出されると、Ｓ２０１でＹｅｓと判定される。ロープ４が第２方向に移動していることが方向検出部２３によって検出されると、Ｓ２０２でＹｅｓと判定される。 FIG. 8 is a flowchart showing another operation example of the inspection device 11. FIG. When the control device 16 includes the direction detection unit 23 , the control device 16 determines the moving direction of the rope 4 . For example, when the direction detection unit 23 detects that the rope 4 is moving in the first direction, it is determined as Yes in S201. When the direction detection unit 23 detects that the rope 4 is moving in the second direction, the determination in S202 is Yes.
　本実施の形態に示す例では、かご１が上方に移動していれば、Ｓ２０１でＹｅｓと判定される。Ｓ２０１でＹｅｓと判定されると、判定部２１は、破断部４ｃが存在するか否かを判定する（Ｓ２０３）。Ｓ２０３に示す処理は、Ｓ１０１に示す処理と同様である。検出器１３によって破断部４ｃの存在が検出されると、Ｓ２０３でＹｅｓと判定される。 In the example shown in the present embodiment, if the car 1 is moving upward, S201 is determined to be Yes. If it is determined as Yes in S201, the determining section 21 determines whether or not the fracture portion 4c exists (S203). The processing shown in S203 is the same as the processing shown in S101. When the detector 13 detects the presence of the broken portion 4c, the determination in S203 is Yes.
　Ｓ２０３でＹｅｓと判定される、即ち、ロープ４が第１方向に移動している時に破断部４ｃが存在することが検出器１３によって検出されると、制御部２２は、マーキング装置１４にマーキング処理を行わせる（Ｓ２０４）。Ｓ２０４では、制御部２２は、マーキング装置１５にマーキング処理を行わせない。この時、制御部２２は、破断部４ｃにも印１４ａが付されるように、マーキング装置１４を制御しても良い。 When it is determined as Yes in S203, that is, when the detector 13 detects that the broken portion 4c exists while the rope 4 is moving in the first direction, the controller 22 instructs the marking device 14 to carry out the marking process. (S204). In S204, the control unit 22 does not allow the marking device 15 to perform the marking process. At this time, the control unit 22 may control the marking device 14 so that the mark 14a is also attached to the fractured portion 4c.
　制御装置１６は、速度検出部２４を更に備えても良い。速度検出部２４は、ロープ４が移動する速度を検出する。検査装置１１にローラ１８が備えられていれば、速度検出部２４は、ローラ１８が回転する速度からロープ４が移動する速度を検出できる。 The control device 16 may further include a speed detection section 24 . The speed detector 24 detects the speed at which the rope 4 moves. If the inspection device 11 is provided with the rollers 18, the speed detection unit 24 can detect the speed at which the rope 4 moves from the speed at which the rollers 18 rotate.
　速度検出部２４は、ロープ４が移動する速度を具体的な数値として検出できなくても良い。例えば、第３釦及び第４釦（図示せず）が入力装置１７として検査装置１１に更に備えられる。速度検出部２４は、第３釦が押されていれば、ロープ４が高速で移動していることを検出する。速度検出部２４は、第４釦が押されていれば、ロープ４が低速で移動していることを検出する。検査装置１１に、ロープ４が中速で移動していることを検出するための第５釦が入力装置１７として更に備えられても良い。 The speed detection unit 24 does not have to be able to detect the speed at which the rope 4 moves as a specific numerical value. For example, a third button and a fourth button (not shown) are further provided on the inspection device 11 as the input device 17 . The speed detection unit 24 detects that the rope 4 is moving at high speed if the third button is pressed. The speed detector 24 detects that the rope 4 is moving at a low speed if the fourth button is pressed. The inspection device 11 may further include a fifth button as the input device 17 for detecting that the rope 4 is moving at medium speed.
　制御装置１６が速度検出部２４を備える場合、制御部２２は、Ｓ２０４において、速度検出部２４によって検出された速度に基づいて、マーキング装置１４を制御しても良い。例えば、制御部２２は、当該速度に基づいて、マーキング処理の開始タイミングと終了タイミングとを決定する。他の例として、制御部２２は、当該速度に基づいて、破断部４ｃにも印１４ａが付されるようにマーキング処理の終了タイミングを決定しても良い。 When the control device 16 includes the speed detection unit 24, the control unit 22 may control the marking device 14 based on the speed detected by the speed detection unit 24 in S204. For example, the control unit 22 determines the start timing and end timing of the marking process based on the speed. As another example, the control unit 22 may determine the end timing of the marking process based on the speed so that the mark 14a is also attached to the fractured portion 4c.
　また、かご１が下方に移動していれば、Ｓ２０２でＹｅｓと判定される。Ｓ２０２でＹｅｓと判定されると、判定部２１は、破断部４ｃが存在するか否かを判定する（Ｓ２０５）。Ｓ２０５に示す処理は、Ｓ１０１に示す処理と同様である。検出器１３によって破断部４ｃの存在が検出されると、Ｓ２０５でＹｅｓと判定される。 Also, if the car 1 is moving downward, it is determined as Yes in S202. If it is determined as Yes in S202, the determination unit 21 determines whether or not the fractured portion 4c exists (S205). The processing shown in S205 is the same as the processing shown in S101. When the detector 13 detects the presence of the broken portion 4c, the determination in S205 is Yes.
　Ｓ２０５でＹｅｓと判定される、即ち、ロープ４が第２方向に移動している時に破断部４ｃが存在することが検出器１３によって検出されると、制御部２２は、マーキング装置１５にマーキング処理を行わせる（Ｓ２０６）。Ｓ２０６では、制御部２２は、マーキング装置１４にマーキング処理を行わせない。この時、制御部２２は、破断部４ｃにも印１５ａが付されるように、マーキング装置１５を制御しても良い。 When it is determined as Yes in S205, that is, when the detector 13 detects that the broken portion 4c exists while the rope 4 is moving in the second direction, the control unit 22 instructs the marking device 15 to carry out the marking process. (S206). In S206, the control unit 22 does not allow the marking device 14 to perform the marking process. At this time, the control unit 22 may control the marking device 15 so that the mark 15a is also attached to the fractured portion 4c.
　制御装置１６が速度検出部２４を備えていれば、制御部２２は、Ｓ２０６において、速度検出部２４によって検出された速度に基づいて、マーキング装置１５を制御しても良い。例えば、制御部２２は、当該速度に基づいて、マーキング処理の開始タイミングと終了タイミングとを決定する。他の例として、制御部２２は、当該速度に基づいて、破断部４ｃにも印１５ａが付されるように、マーキング処理の終了タイミングを決定しても良い。 If the control device 16 includes the speed detection unit 24, the control unit 22 may control the marking device 15 based on the speed detected by the speed detection unit 24 in S206. For example, the control unit 22 determines the start timing and end timing of the marking process based on the speed. As another example, the control unit 22 may determine the end timing of the marking process based on the speed so that the mark 15a is also attached to the fractured portion 4c.
