　次に、図１２は、実施の形態１のガイドレール加工方法を示すフローチャートである。加工装置本体７によりかごガイドレール２に加工を施す場合、まずステップＳ１において、加工制御装置５２と図示しない電源とをかご３に搬入する。また、ステップＳ２において、加工装置本体７を昇降路１のピットに搬入する。このとき、加工装置本体７には、移動検出装置５１が取り付けられているとともに、吊り下げ部材８が接続されている。 Next, FIG. 12 is a flowchart showing the guide rail processing method according to the first embodiment. When the car guide rail 2 is processed by the processing device body 7, first, in step S1, the processing control device 52 and a power source (not shown) are loaded into the car 3. Further, in step S2, the processing apparatus main body 7 is carried into the pit of the hoistway 1. At this time, the movement detection device 51 is attached to the processing device main body 7, and the suspension member 8 is connected thereto.
　続いて、かご３を昇降路１の下部に移動させておき、ステップＳ３において、吊り下げ部材８をかご３に接続して、加工装置本体７を昇降路１内に吊り下げる。また、ステップＳ４において、加工装置本体７を加工制御装置５２及び電源に接続する。また、移動検出装置５１を加工制御装置５２に接続する。そして、ステップＳ５、６において、加工装置本体７をかごガイドレール２にセットする。 Next, the car 3 is moved to the lower part of the hoistway 1, and in step S3, the suspending member 8 is connected to the car 3 to suspend the processing device body 7 in the hoistway 1. Further, in step S4, the processing apparatus main body 7 is connected to the processing control apparatus 52 and the power source. Further, the movement detection device 51 is connected to the processing control device 52. Then, in steps S5 and S6, the processing apparatus main body 7 is set on the car guide rail 2.
　具体的には、ステップＳ５において、図１３に示すように、加工具１３が離隔位置に保持され、フレーム分割体２２が解放位置に保持された状態で、ガイドローラ１５，１６を一方の制動面２ｃに接触させる。また、先端面ローラ１９，２０を先端面２ｄに接触させる。 Specifically, in step S5, as shown in FIG. 13, with the processing tool 13 held at the separated position and the frame divided body 22 held at the released position, the guide rollers 15 and 16 are moved to one of the braking surfaces. Contact 2c. Further, the tip end surface rollers 19 and 20 are brought into contact with the tip end surface 2d.
　この後、ステップＳ６において、フレーム分割体２２を挟み込み位置に移動させ、図１４に示すように、ガイドローラ１５，１６と押付ローラ１７，１８との間に案内部２ｂを挟み込ませる。また、検出ローラ３３を制動面２ｃに接触させる。 After that, in step S6, the frame divided body 22 is moved to the sandwiching position, and the guide portion 2b is sandwiched between the guide rollers 15 and 16 and the pressing rollers 17 and 18, as shown in FIG. Further, the detection roller 33 is brought into contact with the braking surface 2c.
　このようにして加工装置本体７をかごガイドレール２にセットした後、ステップＳ７において、加工具１３を回転させる。そして、ステップＳ８において、かご３の最上階への移動を開始するとともに、加工装置本体７の移動方向及び移動速度の監視を開始する。このとき、かご３は、定格速度よりも低速で移動させる。 After setting the processing apparatus main body 7 on the car guide rail 2 in this manner, the processing tool 13 is rotated in step S7. Then, in step S8, the movement of the car 3 to the uppermost floor is started, and the movement direction and the movement speed of the processing apparatus body 7 are started to be monitored. At this time, the car 3 is moved at a speed lower than the rated speed.
　この後、ステップＳ９において、正常な移動、即ち、設定速度以上の上方向への移動が検出されると、加工制御装置５２は、ステップＳ１０において、図１５に示すように、加工具１３及び加工具駆動装置１４を加工位置に移動させる。即ち、加工具１３によって制動面２ｃに加工を施しながら、加工装置本体７をかごガイドレール２に沿って移動させる。 Thereafter, when normal movement, that is, upward movement equal to or greater than the set speed is detected in step S9, the processing control device 52, in step S10, moves the processing tool 13 and the processing tool 13 as shown in FIG. The tool driving device 14 is moved to the processing position. That is, the processing device body 7 is moved along the car guide rail 2 while the braking surface 2c is processed by the processing tool 13.
　この後、かご３が最上階に到着すると、かご３が停止する。ステップＳ１１において、かご３が停止したことが検出されると、加工制御装置５２は、ステップＳ１２において、加工具１３及び加工具駆動装置１４を離隔位置に移動させる。また、加工制御装置５２は、ステップＳ１３において、加工具１３の回転を停止させる。 After this, when car 3 arrives at the top floor, car 3 will stop. When it is detected that the car 3 has stopped in step S11, the processing control device 52 moves the processing tool 13 and the processing tool drive device 14 to the separated position in step S12. Further, the processing control device 52 stops the rotation of the processing tool 13 in step S13.
　この後、ステップＳ１４において、かご３を最下階へ移動させながら、加工量の測定を行う。加工量の測定は、例えば、案内部２ｂの厚さ寸法を測定、又は制動面２ｃの表面粗さを測定することにより行う。 After that, in step S14, the processing amount is measured while moving the car 3 to the lowest floor. The processing amount is measured, for example, by measuring the thickness dimension of the guide portion 2b or measuring the surface roughness of the braking surface 2c.
　この例では、かご３の上昇時のみ制動面２ｃに加工を施すので、かご３の下降時には、加工具１３を制動面２ｃから離しておくのが好ましい。このため、加工制御装置５２は、回転検出器３４により下方向への移動が検出された場合にも、加工具１３及び加工具駆動装置１４を離隔位置に移動させる。 In this example, since the braking surface 2c is processed only when the car 3 is raised, it is preferable to keep the processing tool 13 away from the braking surface 2c when the car 3 is lowered. Therefore, the processing control device 52 moves the processing tool 13 and the processing tool drive device 14 to the separated position even when the rotation detector 34 detects the downward movement.
　かご３が最下階に到着すると、ステップＳ１５において、加工量が予め設定した値に達していたかどうかを確認する。加工量が不十分であった場合、ガイドローラ１５，１６と押付ローラ１７，１８との間に案内部２ｂを挟み込み、ステップＳ７～１４を再度実施する。加工量が十分であった場合、加工完了となる。 When the car 3 arrives at the bottom floor, in step S15, it is confirmed whether or not the processing amount has reached a preset value. When the processing amount is insufficient, the guide portion 2b is sandwiched between the guide rollers 15 and 16 and the pressing rollers 17 and 18, and steps S7 to S14 are performed again. When the processing amount is sufficient, the processing is completed.
　反対側の制動面２ｃに対して加工を施す場合、図４とは左右対称の加工装置本体７を用いるか、又は図４の加工装置本体７を上下反対向きに吊り下げればよい。後者の場合、フレーム本体２１の下端部にも接続具１２を追加すればよい。 When processing is applied to the braking surface 2c on the opposite side, the processing apparatus main body 7 which is symmetrical to that in FIG. 4 may be used, or the processing apparatus main body 7 in FIG. 4 may be hung upside down. In the latter case, the connector 12 may be added to the lower end of the frame body 21.
　上記の加工方法を残りのかごガイドレール２に対しても施すことにより、全ての制動面２ｃに加工を施すことができる。また、２台以上の加工装置本体７により２面以上の制動面２ｃに同時に加工を施すこともできる。 By applying the above processing method to the remaining car guide rails 2, it is possible to process all braking surfaces 2c. Further, two or more processing device bodies 7 can simultaneously process two or more braking surfaces 2c.
　実施の形態１のガイドレール加工方法は、セッティング工程、移動監視工程、及び加工工程を含んでいる。セッティング工程は、加工装置本体７をかごガイドレール２にセットする工程である。 The guide rail machining method of the first embodiment includes a setting process, a movement monitoring process, and a machining process. The setting step is a step of setting the processing apparatus main body 7 on the car guide rail 2.
　移動監視工程は、加工装置本体７をかごガイドレール２に沿って移動させるとともに、かごガイドレール２に対する加工装置本体７の移動方向及び移動速度を検出する工程である。 The movement monitoring step is a step of moving the processing device body 7 along the car guide rail 2 and detecting the moving direction and moving speed of the processing device body 7 with respect to the car guide rail 2.
　加工工程は、加工装置本体７の移動方向が予め指定された方向であり、かつ、加工装置本体７の移動速度が設定速度以上であるときに、加工具１３をかごガイドレール２に接触させて、加工具１３によりかごガイドレール２に加工を施す工程である。 In the processing step, the processing tool 13 is brought into contact with the car guide rail 2 when the moving direction of the processing apparatus main body 7 is a predetermined direction and the moving speed of the processing apparatus main body 7 is equal to or higher than the set speed. This is a step of processing the car guide rail 2 with the processing tool 13.
　次に、実施の形態１のエレベータのリニューアル方法について説明する。実施の形態１では、既設のかごガイドレール２を残したまま、既設のかご３及び既設の非常止め装置５を新設のかご及び新設の非常止め装置に入れ換える。また、実施の形態１のリニューアル方法は、レール加工工程及び入れ換え工程を含む。 Next, the elevator renewal method according to the first embodiment will be described. In the first embodiment, the existing car 3 and the existing emergency stop device 5 are replaced with a new car and the new emergency stop device while leaving the existing car guide rail 2. Moreover, the renewal method of the first embodiment includes a rail processing step and a replacement step.
　レール加工工程では、既設のかごガイドレール２の制動面２ｃの少なくとも一部を、上記のような加工装置本体７を用いて削り取る。このとき、吊り下げ部材８を介して加工装置本体７を既設のかご３に接続し、既設のかご３の移動により加工装置本体７を既設のかごガイドレール２に沿って移動させる。 In the rail processing step, at least a part of the braking surface 2c of the existing car guide rail 2 is scraped off using the processing device body 7 as described above. At this time, the processing apparatus main body 7 is connected to the existing car 3 via the suspending member 8, and the processing apparatus main body 7 is moved along the existing car guide rail 2 by the movement of the existing car 3.
　この後、入れ換え工程を実施する。入れ換え工程では、既設のかごガイドレール２を残したまま、既設のかご３及び既設の非常止め装置５を、新設のかご及び新設の非常止め装置に入れ換える。 After this, carry out the replacement process. In the replacement step, the existing car 3 and the existing emergency stop device 5 are replaced with the new car and the new emergency stop device while leaving the existing car guide rail 2.
　上記のようなガイドレール加工装置１００では、加工装置本体７の移動速度だけでなく、加工装置本体７の移動方向も検出し、加工装置本体７の移動方向及び移動速度に基づいて、加工具１３を加工位置と離隔位置との間で移動させる。このため、適正な加工条件となる移動状態を検出して、加工具１３を自動的に移動させることができる。従って、立てて設置されているかごガイドレール２に対して、より安定した加工を施すことができる。 In the guide rail processing apparatus 100 as described above, not only the moving speed of the processing apparatus main body 7 but also the moving direction of the processing apparatus main body 7 is detected, and the processing tool 13 is detected based on the moving direction and the moving speed of the processing apparatus main body 7. Is moved between the processing position and the separation position. Therefore, it is possible to automatically move the processing tool 13 by detecting a movement state that is an appropriate processing condition. Therefore, it is possible to perform more stable processing on the car guide rail 2 installed upright.
　また、移動検出装置５１は、検出ローラ３３と回転検出器３４とを有している。このため、簡単な構成により、加工装置本体７の移動方向及び移動速度を検出することができる。 Further, the movement detection device 51 has a detection roller 33 and a rotation detector 34. Therefore, the moving direction and moving speed of the processing apparatus body 7 can be detected with a simple configuration.
　また、加工制御装置５２は、加工装置本体７の移動方向が予め指定された方向であり、かつ、加工装置本体７の移動速度が設定速度以上であるときに、加工具１３を加工位置に移動させる。このため、作業者による加工具１３の操作を自動化できるとともに、加工装置本体７の移動速度低下による制動面２ｃの削り過ぎを防止することができる。 Further, the processing control device 52 moves the processing tool 13 to the processing position when the moving direction of the processing device main body 7 is a predetermined direction and the moving speed of the processing device main body 7 is equal to or higher than the set speed. Let Therefore, it is possible to automate the operation of the processing tool 13 by the operator and prevent excessive cutting of the braking surface 2c due to a decrease in the moving speed of the processing apparatus body 7.
　また、加工制御装置５２は、加工装置本体７の移動方向が予め指定された方向と逆方向であるときに、加工具１３を離隔位置に移動させる。このため、作業者による加工具１３の操作を自動化できる。 Further, the processing control device 52 moves the processing tool 13 to the separated position when the moving direction of the processing device body 7 is opposite to the direction designated in advance. Therefore, the operation of the processing tool 13 by the operator can be automated.
　また、加工制御装置５２は、加工装置本体７の移動速度が設定速度未満であるときに、加工具１３を離隔位置に移動させる。このため、加工装置本体７の移動速度低下による制動面２ｃの削り過ぎを防止することができる。 Further, the processing control device 52 moves the processing tool 13 to the separated position when the moving speed of the processing device body 7 is less than the set speed. Therefore, it is possible to prevent excessive cutting of the braking surface 2c due to a decrease in the moving speed of the processing device body 7.
　また、実施の形態１のガイドレール加工方法では、加工装置本体７の移動方向が予め指定された方向であり、かつ、加工装置本体７の移動速度が設定速度以上であるときに、加工具１３を加工位置に移動させる。このため、立てて設置されているかごガイドレール２に対して、より安定した加工を施すことができる。また、加工装置本体７の移動速度低下による制動面２ｃの削り過ぎを防止することができる。 In the guide rail machining method according to the first embodiment, when the moving direction of the machining device body 7 is a predetermined direction and the traveling speed of the machining device body 7 is equal to or higher than the set speed, the machining tool 13 is used. To the processing position. Therefore, it is possible to perform more stable processing on the car guide rail 2 installed upright. Further, it is possible to prevent excessive cutting of the braking surface 2c due to a decrease in the moving speed of the processing device body 7.
　また、かごガイドレール２のほぼ全長に渡って、制動面２ｃを均等に加工することができる。 Also, the braking surface 2c can be uniformly processed over almost the entire length of the car guide rail 2.
　また、加工装置本体７は、吊り下げ部材８により吊り下げられている。このため、制動面２ｃの加工中に、かご３の振動が加工装置本体７に伝わるのを防止することができる。これにより、加工不具合の発生を防止し、制動面２ｃを安定して加工することができる。 Also, the processing device body 7 is suspended by a suspension member 8. Therefore, it is possible to prevent the vibration of the car 3 from being transmitted to the processing apparatus main body 7 during the processing of the braking surface 2c. As a result, it is possible to prevent processing defects from occurring and to stably process the braking surface 2c.
　また、加工装置本体７は、かご３から吊り下げられる。このため、加工装置本体７を揚重する装置を別途用意する必要がない。また、かごガイドレール２の非常止め装置５が把持する領域に、効率的に加工を施すことができる。また、昇降行程が長いエレベータにおいても、長い吊り下げ部材を用いることなく、かごガイドレール２のほぼ全長に渡って容易に加工を施すことができる。 Also, the processing device body 7 is suspended from the car 3. Therefore, it is not necessary to separately prepare a device for lifting the processing device body 7. Further, the region of the car guide rail 2 gripped by the safety device 5 can be efficiently processed. Further, even in an elevator having a long up-and-down stroke, the car guide rail 2 can be easily processed over almost the entire length without using a long suspending member.
　また、加工装置本体７には、ガイドローラ１５，１６が設けられている。このため、加工具１３の外周面をより確実に制動面２ｃに平行に接触させることができ、削り残しを発生させずに、制動面２ｃに均等に加工を施すことができる。 Further, the processing device main body 7 is provided with guide rollers 15 and 16. For this reason, the outer peripheral surface of the processing tool 13 can be more reliably brought into contact with the braking surface 2c in parallel, and the braking surface 2c can be uniformly processed without causing uncut portions.
　また、案内部２ｂは、ガイドローラ１５，１６と押付ローラ１７，１８との間に挟み込まれる。このため、加工具１３の外周面をより安定して制動面２ｃに平行に接触させることができる。また、制動面２ｃに上下方向の傾きがあった場合にも、加工具１３の外周面と制動面２ｃとの平行を維持することができる。 Further, the guide portion 2b is sandwiched between the guide rollers 15 and 16 and the pressing rollers 17 and 18. Therefore, the outer peripheral surface of the processing tool 13 can be more stably brought into contact with the braking surface 2c in parallel. Further, even when the braking surface 2c is tilted in the vertical direction, the outer peripheral surface of the processing tool 13 and the braking surface 2c can be kept parallel to each other.
　また、フレーム本体２１には、接続具１２が設けられている。このため、接続具１２に吊り下げ部材８を接続して昇降路１内に吊り下げた状態で、加工装置本体７をかごガイドレール２に沿って移動させることができる。これにより、非常止め装置５に対するかごガイドレール２の状態を、昇降路１にかごガイドレール２を設置したまま、より適正な状態にすることができる。 Further, the frame body 21 is provided with the connecting tool 12. Therefore, the processing apparatus main body 7 can be moved along the car guide rail 2 in a state in which the suspending member 8 is connected to the connecting tool 12 and is suspended in the hoistway 1. Accordingly, the state of the car guide rail 2 with respect to the safety device 5 can be made more appropriate while the car guide rail 2 is installed in the hoistway 1.
　また、加工具１３の上方に第１のガイドローラ１５が配置され、加工具１３の下方に第２のガイドローラ１６が配置されている。このため、加工具１３の外周面と制動面２ｃとの平行をより安定して維持することができる。これにより、かごガイドレール２の上下方向の傾き、曲がり、又はうねりがあった場合にも、加工具１３の外周面と制動面２ｃとの平行を維持することができる。 The first guide roller 15 is arranged above the processing tool 13, and the second guide roller 16 is arranged below the processing tool 13. Therefore, the parallelism between the outer peripheral surface of the processing tool 13 and the braking surface 2c can be maintained more stably. As a result, even when the car guide rail 2 is tilted, bent, or undulated in the vertical direction, the outer peripheral surface of the processing tool 13 and the braking surface 2c can be kept parallel to each other.
　また、加工具１３は、第１及び第２のガイドローラ１５，１６の中間位置に配置されている。このため、フレーム本体２１に対する加工具１３の移動方向を、制動面２ｃに直角な方向とすることができる。これにより、加工具１３を制動面２ｃに押し付ける力を安定させることができる。また、加工のムラ、即ち削り取る量の不均一が発生することがなく、安定した加工を施すことができる。 The processing tool 13 is arranged at an intermediate position between the first and second guide rollers 15 and 16. Therefore, the moving direction of the processing tool 13 with respect to the frame body 21 can be set to the direction perpendicular to the braking surface 2c. This makes it possible to stabilize the force with which the processing tool 13 is pressed against the braking surface 2c. Further, it is possible to perform stable processing without causing unevenness in processing, that is, non-uniformity in the amount of scraping.
　また、フレーム１１は、フレーム本体２１とフレーム分割体２２とに分割されている。そして、フレームばね２８は、フレーム分割体２２を挟み込み位置側へ移動させる力を発生している。このため、簡単な構成により、ガイドローラ１５，１６と押付ローラ１７，１８との間に案内部２ｂを安定して挟み込むことができる。 Also, the frame 11 is divided into a frame body 21 and a frame division body 22. Then, the frame spring 28 generates a force for moving the frame divided body 22 to the sandwiching position side. Therefore, the guide portion 2b can be stably sandwiched between the guide rollers 15 and 16 and the pressing rollers 17 and 18 with a simple configuration.
　また、加工具１３及び加工具駆動装置１４は、加工位置と離隔位置との間で移動可能となっている。そして、加工具ばね３１は、加工具１３及び加工具駆動装置１４を加工位置側へ移動させる力を発生している。このため、簡単な構成により、加工具１３を安定して制動面２ｃに押し当て、安定した加工を施すことができる。また、加工具１３を離隔位置に移動させることで、制動面２ｃを加工せずに加工装置本体７をかごガイドレール２に沿って移動させることもできる。 Further, the processing tool 13 and the processing tool drive device 14 are movable between the processing position and the separated position. Then, the processing tool spring 31 generates a force that moves the processing tool 13 and the processing tool drive device 14 to the processing position side. Therefore, it is possible to stably press the processing tool 13 against the braking surface 2c and perform stable processing with a simple configuration. Further, by moving the processing tool 13 to the separated position, the processing device main body 7 can be moved along the car guide rail 2 without processing the braking surface 2c.
　また、フレーム本体２１には、先端面ローラ１９，２０が設けられている。このため、加工装置本体７をかごガイドレール２に沿って安定した姿勢でスムーズに移動させることができる。 Further, the frame body 21 is provided with front end surface rollers 19 and 20. Therefore, the processing device body 7 can be smoothly moved along the car guide rail 2 in a stable posture.
　ここで、従来のエレベータのリニューアル工事において、既設のかごを新設のかごと入れ換える場合がある。この場合、既設のかごに搭載されている既設の非常止め装置も、新設の非常止め装置に入れ換えられる。また、非常止め装置に対するかごガイドレールの摩擦係数は、非常止め装置とかごガイドレールとの組み合わせで決まる。このため、既設のかごを新設のかごと入れ換える場合、既設のかごガイドレールも新設のかごガイドレールと入れ換えられる。 Here, in the existing elevator renewal work, the existing car may be replaced with the new car. In this case, the existing emergency stop device mounted on the existing car is also replaced with the new emergency stop device. The friction coefficient of the car guide rail with respect to the safety gear is determined by the combination of the safety gear and the car guide rail. Therefore, when replacing the existing car with the new car, the existing car guide rail can also be replaced with the new car guide rail.
　しかし、この場合、既設のかごガイドレール及び新設のかごガイドレールの搬送等に手間がかかり、工期が長くなる。また、コストも高くなる。 However, in this case, it takes time and effort to carry the existing car guide rails and the new car guide rails, and the construction period becomes long. Also, the cost is high.
　これに対して、上記のようなガイドレール加工装置１００及びガイドレール加工方法では、吊り下げ部材８を介して加工装置本体７が昇降路１内に吊り下げられる。そして、加工具１３により制動面２ｃに加工を施しながら加工装置本体７がかごガイドレール２に沿って移動される。このため、非常止め装置５に対するかごガイドレール２の摩擦係数を、かごガイドレール２を昇降路１に設置したまま、より適正化することができる。 On the other hand, in the guide rail processing apparatus 100 and the guide rail processing method as described above, the processing apparatus main body 7 is suspended in the hoistway 1 via the suspension member 8. Then, the processing device body 7 is moved along the car guide rail 2 while the braking surface 2c is processed by the processing tool 13. Therefore, the friction coefficient of the car guide rail 2 with respect to the emergency stop device 5 can be further optimized while the car guide rail 2 is installed in the hoistway 1.
　これにより、既設のかごガイドレール２を取り換えることなく、エレベータのリニューアルを実現することができる。従って、工期を大幅に短縮することができるとともに、工事にかかる費用も大幅に削減することができる。 With this, the elevator can be renewed without replacing the existing car guide rail 2. Therefore, the construction period can be significantly shortened and the construction cost can be significantly reduced.
　また、加工装置本体７を既設のかご３を利用して移動させるので、加工時に発生する加工屑等が新設のかご及び新設の非常止め装置５に付着するのを防止することができる。 Further, since the processing apparatus main body 7 is moved by using the existing cage 3, it is possible to prevent processing scraps generated during processing from adhering to the new cage and the new emergency stop device 5.
　なお、上記の例では、加工装置本体７を上昇させながら制動面２ｃに加工を施したが、加工装置本体７を下降させながら制動面２ｃに加工を施してもよい。その場合、回転検出器３４が加工装置本体７の移動方向を監視しているので、移動方向に合わせて、加工制御装置５２により、適切な加工具１３の回転方向を設定することができる。これにより、加工装置本体７を上昇させながら加工した場合と同等に、かごガイドレール２に対して安定して加工を施すことができる。 In the above example, the braking surface 2c is processed while the processing device body 7 is raised, but the braking surface 2c may be processed while the processing device body 7 is lowered. In this case, since the rotation detector 34 monitors the moving direction of the processing device body 7, the processing control device 52 can set an appropriate rotating direction of the processing tool 13 in accordance with the moving direction. As a result, the car guide rail 2 can be stably processed in the same manner as when the processing device body 7 is raised.
　また、加工装置本体７を上昇させながら加工量を測定してもよい。また、加工と加工量の測定とを同時に実施してもよい。 Alternatively, the processing amount may be measured while raising the processing device body 7. Further, the processing and the measurement of the processing amount may be performed at the same time.
　実施の形態２．
　次に、図１６は、この発明の実施の形態２によるガイドレール加工装置１００を示すブロック図である。実施の形態２のガイドレール加工装置１００は、加工装置本体７、吊り下げ部材８、移動検出装置５１、及び加工制御装置５２に加えて、第１の外れ検出器３８及び第２の外れ検出器３９を有している。なお、図１６では、吊り下げ部材８を省略している。 Embodiment 2.
Next, FIG. 16 is a block diagram showing a guide rail processing apparatus 100 according to Embodiment 2 of the present invention. The guide rail processing apparatus 100 according to the second embodiment includes the processing apparatus main body 7, the suspension member 8, the movement detection apparatus 51, and the processing control apparatus 52, as well as a first detachment detector 38 and a second detachment detector. Have 39. Note that the hanging member 8 is omitted in FIG.
　第１及び第２の外れ検出器３８，３９は、加工装置本体７がかごガイドレール２から外れたことを検出する。 The first and second detachment detectors 38 and 39 detect that the processing apparatus body 7 is detached from the car guide rail 2.
　移動装置である巻上機５４は、かご３を移動させることにより、加工装置本体７をかごガイドレール２に沿って移動させる。巻上機５４は、エレベータ制御装置５３によって制御される。 The hoist 54, which is a moving device, moves the car body 3 along the car guide rail 2 by moving the car 3. The hoist 54 is controlled by the elevator controller 53.
　加工制御装置５２は、第１及び第２の外れ検出器３８，３９からの情報に基づいて、加工装置本体７を制御する。また、加工制御装置５２は、第１及び第２の外れ検出器３８，３９からの情報に基づいて、エレベータ制御装置５３を介して、巻上機５４を制御する。 The processing control device 52 controls the processing device body 7 based on the information from the first and second detachment detectors 38 and 39. Further, the processing control device 52 controls the hoisting machine 54 via the elevator control device 53 based on the information from the first and second detachment detectors 38 and 39.
　加工制御装置５２は、かごガイドレール２への加工中に加工装置本体７がかごガイドレール２から外れた場合、加工具１３を離隔位置に移動させる。また、加工制御装置５２は、かごガイドレール２への加工中に加工装置本体７がかごガイドレール２から外れた場合、加工具１３の回転を停止させる。 The processing control device 52 moves the processing tool 13 to the separated position when the processing device body 7 comes off the car guide rail 2 during processing on the car guide rail 2. Further, the processing control device 52 stops the rotation of the processing tool 13 when the processing device body 7 comes off from the car guide rail 2 during processing on the car guide rail 2.
　また、加工制御装置５２は、かごガイドレール２への加工中に加工装置本体７がかごガイドレール２から外れた場合、加工装置本体７の移動を停止させる。 Further, the machining control device 52 stops the movement of the machining device body 7 when the machining device body 7 comes off the car guide rail 2 during machining on the car guide rail 2.
　図１７は、図１６の加工装置本体７を示す斜視図である。第１の外れ検出器３８は、フレーム本体２１の上端部に設けられている。第２の外れ検出器３９は、フレーム本体２１の下端部に設けられている。 FIG. 17 is a perspective view showing the processing apparatus main body 7 of FIG. The first detachment detector 38 is provided at the upper end of the frame body 21. The second detachment detector 39 is provided at the lower end of the frame body 21.
　また、第１の外れ検出器３８は、加工装置本体７をかごガイドレール２に沿って移動させるときに、フレーム本体２１の上端部と先端面２ｄとの距離を検出する。第２の外れ検出器３９は、加工装置本体７をかごガイドレール２に沿って移動させるときに、フレーム本体２１の下端部と先端面２ｄとの距離を検出する。 Further, the first detachment detector 38 detects the distance between the upper end of the frame body 21 and the tip surface 2d when the processing device body 7 is moved along the car guide rail 2. The second detachment detector 39 detects the distance between the lower end portion of the frame body 21 and the tip surface 2d when the processing device body 7 is moved along the car guide rail 2.
　第１及び第２の外れ検出器３８，３９としては、例えば渦電流式変位センサが用いられる。加工制御装置５２は、フレーム本体２１と先端面２ｄとの距離が設定値以上になると、加工装置本体７がかごガイドレール２から外れたと判定する。他の構成は、実施の形態１と同様である。 As the first and second detachment detectors 38 and 39, for example, eddy current type displacement sensors are used. The processing control device 52 determines that the processing device main body 7 is disengaged from the car guide rail 2 when the distance between the frame main body 21 and the front end surface 2d is equal to or greater than the set value. Other configurations are similar to those of the first embodiment.
　次に、実施の形態２のガイドレール加工方法は、実施の形態１の加工方法に加えて、加工装置本体７をかごガイドレール２に沿って移動させる際に、加工装置本体７のかごガイドレール２からの外れを監視する。 Next, in addition to the machining method of the first embodiment, the guide rail machining method of the second embodiment includes a car guide rail of the machining apparatus body 7 when the machining apparatus body 7 is moved along the car guide rail 2. Watch for deviations from 2.
　制動面２ｃの加工時に、加工装置本体７がかごガイドレール２から外れた場合、加工制御装置５２は、加工具１３及び加工具駆動装置１４を離隔位置に移動させるとともに、加工具１３の回転を停止させる。また、加工制御装置５２は、かご３を停止させる指令をエレベータ制御装置５３に出力する。 When the processing device body 7 is disengaged from the car guide rail 2 during processing of the braking surface 2c, the processing control device 52 moves the processing tool 13 and the processing tool drive device 14 to the separated position, and rotates the processing tool 13 at the same time. Stop. Further, the processing control device 52 outputs a command to stop the car 3 to the elevator control device 53.
　即ち、かごガイドレール２への加工中に加工装置本体７がかごガイドレール２から外れた場合に、加工制御装置５２は、加工具１３による加工と、加工装置本体７の移動とを停止させる。 That is, when the processing device body 7 comes off from the car guide rail 2 during processing on the car guide rail 2, the processing control device 52 stops the processing by the processing tool 13 and the movement of the processing device body 7.
　また、かご３を最下階へ移動させながら加工量の測定を行うときに、加工装置本体７がかごガイドレール２から外れた場合、加工制御装置５２は、かご３を停止させる指令をエレベータ制御装置５３に出力する。他のガイドレール加工方法は、実施の形態１と同様である。 Further, when the processing amount is measured while moving the car 3 to the lowest floor, if the processing device body 7 is disengaged from the car guide rail 2, the processing control device 52 issues an elevator control command to stop the car 3. Output to the device 53. Other guide rail processing methods are the same as those in the first embodiment.
　このようなガイドレール加工装置１００及びガイドレール加工方法では、加工装置本体７のかごガイドレール２からの外れが監視される。このため、立てて設置されているかごガイドレール２に対して、より安定した加工を施すことができる。 With such a guide rail processing apparatus 100 and a guide rail processing method, the processing apparatus main body 7 is monitored for disengagement from the car guide rail 2. Therefore, it is possible to perform more stable processing on the car guide rail 2 installed upright.
　また、加工制御装置５２は、かごガイドレール２への加工中に加工装置本体７がかごガイドレール２から外れた場合、加工具１３を離隔位置に移動させる。このため、加工装置本体７の外れによる制動面２ｃの加工不良を防止することができる。 Further, the processing control device 52 moves the processing tool 13 to the separated position when the processing device body 7 comes off the car guide rail 2 during processing on the car guide rail 2. Therefore, it is possible to prevent the processing failure of the braking surface 2c due to the removal of the processing apparatus body 7.
　また、加工制御装置５２は、かごガイドレール２への加工中に加工装置本体７がかごガイドレール２から外れた場合、加工具１３の回転を停止させる。このため、加工装置本体７の外れによる制動面２ｃの加工不良を防止することができる。 Further, the processing control device 52 stops the rotation of the processing tool 13 when the processing device body 7 comes off the car guide rail 2 during processing on the car guide rail 2. Therefore, it is possible to prevent the processing failure of the braking surface 2c due to the removal of the processing apparatus body 7.
　また、加工制御装置５２は、かごガイドレール２への加工中に加工装置本体７がかごガイドレール２から外れた場合、加工装置本体７の移動を停止させる。このため、加工装置本体７の外れによる制動面２ｃの加工不良を防止することができる。 Further, the machining control device 52 stops the movement of the machining device body 7 when the machining device body 7 comes off the car guide rail 2 during machining on the car guide rail 2. Therefore, it is possible to prevent the processing failure of the braking surface 2c due to the removal of the processing apparatus body 7.
　なお、実施の形態２では、実施の形態１と同様に、加工装置本体７を上昇させながら制動面２ｃに加工を施した。これに対して、加工装置本体７を下降させながら制動面２ｃに加工を施してもよい。この場合も、加工装置本体７の外れによる制動面２ｃの加工不良を防止することができる。 Note that, in the second embodiment, as in the first embodiment, the braking surface 2c is processed while the processing device body 7 is being raised. On the other hand, the braking surface 2c may be processed while the processing device body 7 is lowered. Also in this case, it is possible to prevent the processing failure of the braking surface 2c due to the detachment of the processing apparatus body 7.
　また、実施の形態２では、移動検出装置５１を省略してもよい。又は、エレベータ制御装置５３からのかご３の移動方向及び移動速度の情報に基づいて、加工制御装置５２により加工具１３を制御してもよい。 Further, in the second embodiment, the movement detection device 51 may be omitted.
