Description

エレベータ装置Elevator equipment
　本発明は、電動操作器によって作動する非常止め装置を備えるエレベータ装置に関する。 The present invention relates to an elevator device including an emergency stop device operated by an electric actuator.
　エレベータ装置には、乗りかごの昇降速度を常時監視して、所定の過速状態に陥った乗りかごを非常停止させるために、ガバナおよび非常止め装置が備えられている。一般に、乗りかごとガバナはガバナロープによって結合されており、過速状態を検出すると、ガバナがガバナロープを拘束することで乗りかご側の非常止め装置を動作させ、乗りかごを非常停止するようになっている。 The elevator device is equipped with a governor and an emergency stop device in order to constantly monitor the ascending / descending speed of the car and to make an emergency stop of the car that has fallen into a predetermined overspeed state. Generally, the car and the governor are connected by a governor rope, and when an overspeed condition is detected, the governor restrains the governor rope to operate the emergency stop device on the car side, and the car is stopped in an emergency. There is.
　このようなエレベータ装置では、昇降路内に長尺物であるガバナロープを敷設するため、省スペース化および低コスト化が難しい。また、ガバナロープが振れる場合、昇降路内における構造物とガバナロープとが干渉しやすくなる。 In such an elevator device, it is difficult to save space and cost because a long governor rope is laid in the hoistway. Further, when the governor rope swings, the structure in the hoistway and the governor rope tend to interfere with each other.
　これに対し、ガバナロープを用いない非常止め装置が提案されている。 On the other hand, an emergency stop device that does not use a governor rope has been proposed.
　ガバナロープを用いない非常止め装置に関する従来技術として、特許文献１に記載された技術が知られている。本従来技術では、乗りかごの下部の二か所に、楔状のブレーキシューを有するブレーキユニットが設けられ、ブレーキシューにはブレーキリンクが接続される。二つのブレーキリンクは、接続部によって互いに接続されており、連動して各ブレーキシューを上下動させて、ブレーキをかけたり、ブレーキを解除したりする。 The technique described in Patent Document 1 is known as a conventional technique relating to an emergency stop device that does not use a governor rope. In the present prior art, brake units having wedge-shaped brake shoes are provided at two places in the lower part of the car, and brake links are connected to the brake shoes. The two brake links are connected to each other by a connecting portion, and in conjunction with each other, the brake shoes are moved up and down to apply the brake and release the brake.
　一方のブレーキユニット側には、ブレーキがかからないようにブレーキリンクの動作をロックしたり、ブレーキをかけるときにロックを解除したりする、ロック部が設けられる。制御部からの指令によりロック部が備えるソレノイドが作動すると、ソレノイドに連動する機構が、解放されたばねの弾性エネルギーによりブレーキリンクを瞬時に上方へ動かす。これにより、ブレーキシューが上方へ引き上げられ、乗りかごが制動される。 On one side of the brake unit, a lock part is provided to lock the operation of the brake link so that the brake is not applied, and to release the lock when applying the brake. When the solenoid provided in the lock unit is activated by a command from the control unit, the mechanism interlocking with the solenoid instantly moves the brake link upward by the elastic energy of the released spring. As a result, the brake shoe is pulled upward and the car is braked.
　他方のブレーキユニット側には、非常止め装置を通常状態へ復帰させる復帰部が設けられる。復帰部が備えるリニアアクチュエータを駆動し、リニアアクチュエータに連動する機構により捻りばねを付勢する。この状態で、制御部からの指令により、乗りかごが少し引き上げられると、捻りばねの付勢力を受けたリンク機構によって、ブレーキシューが、ガイドレールから外れて、引き下げられる。 The other brake unit side is provided with a return unit that returns the emergency stop device to the normal state. The linear actuator provided in the return unit is driven, and the torsion spring is urged by a mechanism interlocked with the linear actuator. In this state, when the car is pulled up a little by a command from the control unit, the brake shoe is disengaged from the guide rail and pulled down by the link mechanism that receives the urging force of the torsion spring.

　上述のように、電動操作器によって作動する従来の非常止め装置は、動作機構の構成が複雑になる。 As described above, in the conventional emergency stop device operated by the electric actuator, the configuration of the operation mechanism becomes complicated.
　そこで、本発明は、電動操作器によって作動しながらも動作機構の複雑化を抑制できるとともに、動作の信頼性を向上することができる非常止め装置を備えるエレベータ装置を提供する。 Therefore, the present invention provides an elevator device provided with an emergency stop device that can suppress the complexity of the operation mechanism while being operated by the electric actuator and can improve the reliability of the operation.
　上記課題を解決するために、本発明によるエレベータ装置は、乗りかごと、乗りかごに設けられる非常止め装置と、乗りかごに設けられ、非常止め装置を動作させる電動操作器と、を備えるものであって、電動操作器は、電磁石と、電磁石の動作に連動して非常止め装置を操作する操作レバーと、操作レバーに接続されるアマチュアと、電磁石が備えるネジ孔部と螺合する送りネジと、送りネジを駆動するモータと、を備え、待機状態において、アマチュアは、電磁石によって吸引され、非常止め装置が作動後、アマチュアが、励磁された電磁石に吸着され、アマチュアを吸着した電磁石が、モータによって駆動された送りネジによって、待機状態における位置に移動され、アマチュアが電磁石とともに移動するとき、第１のローラと送りネジとの距離が一定に保たれる。 In order to solve the above problems, the elevator device according to the present invention includes a car, an emergency stop device provided in the car, and an electric controller provided in the car to operate the emergency stop device. The electric motor includes an electromagnet, an operation lever that operates the emergency stop device in conjunction with the operation of the electromagnet, an amateur connected to the operation lever, and a feed screw that is screwed into the screw hole portion of the electromagnet. In the standby state, the amateur is attracted by the electromagnet, and after the emergency stop device is activated, the amateur is attracted to the excited electromagnet, and the electromagnet that attracts the amateur is the motor. Driven by the lead screw, it is moved to its standby position and the distance between the first roller and the lead screw is kept constant as the amateur moves with the electromagnet.
　本発明によれば、非常止め装置を作動させる動作機構を複雑化することなく、電動操作器の動作の信頼性を向上できる。 According to the present invention, the reliability of the operation of the electric actuator can be improved without complicating the operation mechanism for operating the emergency stop device.

　以下、本発明の一実施形態であるエレベータ装置について、実施例１～２により、図面を用いながら説明する。なお、各図において、参照番号が同一のものは同一の構成要件あるいは類似の機能を備えた構成要件を示している。 Hereinafter, the elevator device according to the embodiment of the present invention will be described with reference to Examples 1 and 2 with reference to the drawings. In each figure, those having the same reference number indicate the same constituent requirements or the constituent requirements having similar functions.
　図１は、本発明の実施例１であるエレベータ装置の概略構成図である。 FIG. 1 is a schematic configuration diagram of an elevator device according to a first embodiment of the present invention.
　図１に示すように、エレベータ装置は、乗りかご１と、位置センサ３と、電動操作器１０と、駆動機構（１２～２０）と、引上げロッド２１と、非常止め装置２とを備えている。 As shown in FIG. 1, the elevator device includes a car 1, a position sensor 3, an electric controller 10, a drive mechanism (12 to 20), a pull-up rod 21, and an emergency stop device 2. ..
　乗りかご１は、建築物に設けられる昇降路内に主ロープ（図示せず）により吊られており、ガイド装置を介してガイドレール４に摺動可能に係合している。駆動装置（巻上機：図示せず）により主ロープが摩擦駆動されると、乗りかご１は昇降路内を昇降する。 The car 1 is suspended by a main rope (not shown) in a hoistway provided in a building, and is slidably engaged with a guide rail 4 via a guide device. When the main rope is frictionally driven by a drive device (winding machine: not shown), the car 1 moves up and down in the hoistway.
　位置センサ３は、乗りかご１に備えられ、昇降路内における乗りかご１の位置を検出するとともに、検出された乗りかご１の位置から乗りかご１の昇降速度を常時検出する。したがって、位置センサ３により、乗りかごの昇降速度が所定の過速度を超えたことを検出することができる。 The position sensor 3 is provided in the car 1, detects the position of the car 1 in the hoistway, and constantly detects the ascending / descending speed of the car 1 from the detected position of the car 1. Therefore, the position sensor 3 can detect that the ascending / descending speed of the car exceeds a predetermined overspeed.
　本実施例１では、位置センサ３は、画像センサを備え、画像センサによって取得されるガイドレール４の表面状態の画像情報に基づいて、乗りかご１の位置および速度を検出する。例えば、予め計測され記憶装置に記憶されるガイドレール４の表面状態の画像情報と、画像センサによって所得される画像情報を照合することにより、乗りかご１の位置が検出される。 In the first embodiment, the position sensor 3 includes an image sensor, and detects the position and speed of the car 1 based on the image information of the surface state of the guide rail 4 acquired by the image sensor. For example, the position of the car 1 is detected by collating the image information of the surface state of the guide rail 4 measured in advance and stored in the storage device with the image information earned by the image sensor.
　なお、位置センサとしては、乗りかごに設けられ、乗りかごの移動とともに回転するロータリーエンコーダを用いてもよい。 As the position sensor, a rotary encoder provided in the car and rotating with the movement of the car may be used.
　電動操作器１０は、本実施例１では電磁操作器であり、乗りかご１の上部に配置される。電磁操作器は、例えば、ソレノイドもしくは電磁石によって作動する可動片もしくは可動杆を備えるものである。電動操作器１０は、位置センサ３が乗りかご１の所定の過速状態を検出したときに作動する。このとき、操作レバー１１に接続されている駆動機構（１２～２０）により、引上げロッド２１が引き上げられる。これにより、非常止め装置２が制動状態となる。 The electric actuator 10 is an electromagnetic actuator in the first embodiment, and is arranged on the upper part of the car 1. The electromagnetic actuator includes, for example, a movable piece or a movable rod operated by a solenoid or an electromagnet. The electric actuator 10 operates when the position sensor 3 detects a predetermined overspeed state of the car 1. At this time, the pulling rod 21 is pulled up by the drive mechanism (12 to 20) connected to the operating lever 11. As a result, the emergency stop device 2 is put into a braking state.
　なお、駆動機構（１２～２０）については後述する。 The drive mechanism (12 to 20) will be described later.
　非常止め装置２は、乗りかご１の左右に一台ずつ配置される。各非常止め装置２が備える図示しない一対の制動子は、制動位置および非制動位置の間で可動であり、制動位置においてガイドレール４を挟持し、さらに、乗りかご１の下降により相対的に上昇すると、制動子とガイドレール４との間に作用する摩擦力により制動力を生じる。これにより、非常止め装置２は、乗りかご１が過速状態に陥ったときに作動し、乗りかご１を非常停止させる。 The emergency stop device 2 is arranged one on each side of the car 1. A pair of brakes (not shown) provided in each emergency stop device 2 is movable between the braking position and the non-braking position, sandwiches the guide rail 4 at the braking position, and further rises relatively by lowering the car 1. Then, a braking force is generated by the frictional force acting between the brake element and the guide rail 4. As a result, the emergency stop device 2 operates when the car 1 falls into an overspeed state, and causes the car 1 to make an emergency stop.
　本実施例１のエレベータ装置は、ガバナロープを用いない、いわゆるロープレスガバナシステムを備えるものであり、乗りかご１の昇降速度が定格速度を超えて第１過速度（例えば、定格速度の１．３倍を超えない速度）に達すると、駆動装置（巻上機）の電源およびこの駆動装置を制御する制御装置の電源が遮断される。また、乗りかご１の下降速度が第２過速度（例えば、定格速度の１．４倍を超えない速度）に達すると、乗りかご１に設けられる電動操作器１０が電気的に駆動され、非常止め装置２を作動させて、乗りかご１が非常停止される。 The elevator device of the first embodiment includes a so-called low press governor system that does not use a governor rope, and the ascending / descending speed of the car 1 exceeds the rated speed and is the first overspeed (for example, 1.3 of the rated speed). When the speed reaches not more than double), the power supply of the drive device (winding machine) and the power supply of the control device that controls this drive device are cut off. Further, when the descending speed of the car 1 reaches the second overspeed (for example, a speed not exceeding 1.4 times the rated speed), the electric controller 10 provided in the car 1 is electrically driven, and it is extremely difficult. The stop device 2 is activated, and the car 1 is stopped in an emergency.
　本実施例１において、ロープレスガバナシステムは、前述の位置センサ３と、位置センサ３の出力信号に基づいて、乗りかご１の過速状態を判定する安全制御装置とから構成される。この安全制御装置は、位置センサ３の出力信号に基づいて乗りかご１の速度を計測し、計測される速度が第１過速度に達したと判定すると、駆動装置（巻上機）の電源およびこの駆動装置を制御する制御装置の電源を遮断するための指令信号を出力する。また、安全制御装置は、計測される速度が第２過速度に達したと判定すると、電動操作器１０を作動するための指令信号を出力する。 In the first embodiment, the low press governor system includes the above-mentioned position sensor 3 and a safety control device that determines an overspeed state of the car 1 based on the output signal of the position sensor 3. This safety control device measures the speed of the car 1 based on the output signal of the position sensor 3, and when it is determined that the measured speed has reached the first overspeed, the power supply of the drive device (winding machine) and A command signal for shutting off the power supply of the control device that controls this drive device is output. Further, when the safety control device determines that the measured speed has reached the second overspeed, the safety control device outputs a command signal for operating the electric controller 10.
　前述のように、非常止め装置２が備える一対の制動子が引上げロッド２１によって引き上げられると、一対の制動子がガイドレール４を挟持する。引上げロッド２１は、電動操作器１０に接続される駆動機構（１２～２０）によって駆動される。 As described above, when the pair of brakes provided in the emergency stop device 2 is pulled up by the pulling rod 21, the pair of brakes sandwich the guide rail 4. The pulling rod 21 is driven by a drive mechanism (12 to 20) connected to the electric actuator 10.
　以下、この駆動機構の構成について説明する。 The configuration of this drive mechanism will be described below.
　電動操作器１０の操作レバー１１と第１の作動片１６が連結され、略Ｔ字状の第１リンク部材が構成される。操作レバー１１および第１の作動片１６はそれぞれＴ字の頭部および足部を構成する。略Ｔ字状の第１リンク部材は、操作レバー１１と第１の作動片１６の連結部において、第１の作動軸１９を介してクロスヘッド（図１中の「５０」）に回動可能に支持される。Ｔ字の足部となる作動片１６における操作レバー１１と作動片１６の連結部とは反対側の端部に、一対の引上げロッド２１の内の一方（図中左側）の引上げロッドの端部が接続される。 The operating lever 11 of the electric actuator 10 and the first operating piece 16 are connected to form a substantially T-shaped first link member. The operating lever 11 and the first actuating piece 16 form a T-shaped head and foot, respectively. The substantially T-shaped first link member is rotatable to a crosshead (“50” in FIG. 1) via the first operating shaft 19 at the connecting portion between the operating lever 11 and the first operating piece 16. Is supported by. The end of the pulling rod of one of the pair of pulling rods 21 (left side in the figure) at the end of the working piece 16 which is the T-shaped foot on the opposite side of the connecting portion between the operating lever 11 and the working piece 16. Is connected.
　接続片１７と第２の作動片１８が連結され、略Ｔ字状の第２リンク部材が構成される。接続片１７および第２の作動片１８はそれぞれＴ字の頭部および足部を構成する。略Ｔ字状の第２リンク部材は、接続片１７と第２の作動片１８の連結部において、第２の作動軸２０を介してクロスヘッドに回動可能に支持される。Ｔ字の足部となる第２の作動片１８における接続片１７と第２の作動片１８の連結部とは反対側の端部に、一対の引上げロッド２１の内の他方（図中右側）の引上げロッドの端部が接続される。 The connecting piece 17 and the second operating piece 18 are connected to form a substantially T-shaped second link member. The connecting piece 17 and the second working piece 18 form a T-shaped head and foot, respectively. The substantially T-shaped second link member is rotatably supported by the crosshead via the second operating shaft 20 at the connecting portion between the connecting piece 17 and the second operating piece 18. The other of the pair of pulling rods 21 (on the right side in the figure) at the end of the second operating piece 18 which is the T-shaped foot, opposite to the connecting portion of the connecting piece 17 and the second operating piece 18. The end of the pulling rod is connected.
　筐体３０の内部から外部に伸びる操作レバー１１の端部と、接続片１７の両端部の内、第２の作動軸２０よりも乗りかご１の上部に近い端部とが、それぞれ、乗りかご１上に横たわる駆動軸１２の一端（図中左側）と他端（図中右側）とに接続される。駆動軸１２は、クロスヘッドに固定される固定部１４を摺動可能に貫通している。また、駆動軸１２は、押圧部材１５を貫通し、押圧部材は駆動軸１２に固定されている。なお、押圧部材１５は、固定部１４の第２リンク部材（接続片１７、第２の作動片１８）側に位置する。固定部１４と押圧部材１５の間に、弾性体である駆動ばね１３（圧縮ばね）が位置し、駆動ばね１３には駆動軸１２が挿通される。 The end of the operating lever 11 extending from the inside of the housing 30 to the outside and the end of both ends of the connecting piece 17 closer to the upper part of the car 1 than the second operating shaft 20 are the car, respectively. 1 It is connected to one end (left side in the figure) and the other end (right side in the figure) of the drive shaft 12 lying on it. The drive shaft 12 slidably penetrates the fixing portion 14 fixed to the crosshead. Further, the drive shaft 12 penetrates the pressing member 15, and the pressing member is fixed to the drive shaft 12. The pressing member 15 is located on the side of the second link member (connecting piece 17, second operating piece 18) of the fixing portion 14. A drive spring 13 (compression spring), which is an elastic body, is located between the fixed portion 14 and the pressing member 15, and the drive shaft 12 is inserted through the drive spring 13.
　電動操作器１０が作動すると、すなわち本実施例１では電磁石への通電が遮断されると、駆動ばね１３の付勢力に抗して操作レバー１１の動きを拘束する電磁力が消失するので、押圧部材１５に加わる駆動ばね１３の付勢力によって、駆動軸１２が長手方向に沿って駆動される。このため、第１リンク部材（操作レバー１１、第１の作動片１６）が第１の作動軸１９の回りに回動するとともに、第２リンク部材（接続片１７、第２の作動片１８）が第２の作動軸２０の回りに回動する。これにより、第１リンク部材の第１の作動片１６に接続される一方の引上げロッド２１が駆動されて引き上げられるとともに、第２リンク部材の第２の作動片１８に接続される他方の引上げロッド２１が駆動されて引き上げられる。 When the electric actuator 10 is activated, that is, when the energization of the electromagnet is cut off in the first embodiment, the electromagnetic force that restrains the movement of the operating lever 11 against the urging force of the drive spring 13 disappears, so that the pressing force is applied. The drive shaft 12 is driven along the longitudinal direction by the urging force of the drive spring 13 applied to the member 15. Therefore, the first link member (operation lever 11, the first operating piece 16) rotates around the first operating shaft 19, and the second link member (connecting piece 17, the second operating piece 18). Rotates around the second actuating shaft 20. As a result, one pulling rod 21 connected to the first working piece 16 of the first link member is driven and pulled up, and the other pulling rod connected to the second working piece 18 of the second link member is driven. 21 is driven and pulled up.
　図２は、本実施例１における電動操作器１０の機構部を示し、図１の設置状態における正面図である。なお、図２において、非常止め装置は非作動状態であり、電動操作器１０は待機状態にある。すなわち、エレベータ装置は、通常の稼動状態である。 FIG. 2 shows the mechanical portion of the electric actuator 10 in the first embodiment, and is a front view in the installed state of FIG. In FIG. 2, the emergency stop device is in the non-operating state, and the electric actuator 10 is in the standby state. That is, the elevator device is in a normal operating state.
　図２に示すように、待機状態においては、操作レバー１１に接続されるアマチュア３４が、励磁されている電磁石３５に吸引されている。これにより、駆動ばね１３（図１）の付勢力に抗して、操作レバー１１の動きが拘束されている。なお、アマチュア３４における少なくとも電磁石３５と吸着する部分は磁性体、好ましくは軟磁性体からなる。 As shown in FIG. 2, in the standby state, the amateur 34 connected to the operation lever 11 is attracted to the electromagnet 35 being excited. As a result, the movement of the operating lever 11 is restrained against the urging force of the drive spring 13 (FIG. 1). At least the portion of the amateur 34 that adsorbs to the electromagnet 35 is made of a magnetic material, preferably a soft magnetic material.
　操作レバー１１は、アマチュア３４に設けられるアマチュアブラケット３８が有する操作レバー接続部３３に、回動可能に接続される。操作レバー１１は、操作レバー接続部３３と接続される端部に、操作レバーの長手方向に沿って延びる長孔６０を有する。操作レバー１１は、長孔６０を貫通するローラ３９を介して、操作レバー接続部３３と摺動可能に接続される。 The operation lever 11 is rotatably connected to the operation lever connection portion 33 of the amateur bracket 38 provided on the amateur 34. The operating lever 11 has an elongated hole 60 extending along the longitudinal direction of the operating lever at an end connected to the operating lever connecting portion 33. The operating lever 11 is slidably connected to the operating lever connecting portion 33 via a roller 39 penetrating the elongated hole 60.
　図示しない安全制御装置からの指令により、電磁石３５の励磁が停止されると、アマチュア３４に作用する吸引力が消失する。これにより、アマチュア３４の電磁的拘束が解けるので、駆動ばね１３（図１）の付勢力によって駆動軸１２が駆動される。ここで、アマチュア３４は、後述する復帰機構部（３６，３７，４１，４２）とは機械的には接続されておらず、復帰機構部（３６，３７，４１，４２）からは機械的に自由な状態にある。 When the excitation of the electromagnet 35 is stopped by a command from a safety control device (not shown), the attractive force acting on the amateur 34 disappears. As a result, the electromagnetic restraint of the amateur 34 is released, so that the drive shaft 12 is driven by the urging force of the drive spring 13 (FIG. 1). Here, the amateur 34 is not mechanically connected to the return mechanism unit (36,37,41,42) described later, and is mechanically connected to the return mechanism unit (36,37,41,42). It is in a free state.
　駆動軸１２が駆動されると、駆動軸１２に接続される操作レバー１１が第１の作動軸１９の回りに回動し、連動して、操作レバー１１に連結される第１の作動片１６が第１の作動軸１９の回りに回動する。これにより、第１の作動片１６に接続される引上げロッド２１が引き上げられる。引上げロッド２１が引き上げられると、非常止め装置２が備える楔状の一対の制動子２２が引き上げられる。なお、本実施例１における非常止め装置２は、公知技術によるものである。 When the drive shaft 12 is driven, the operation lever 11 connected to the drive shaft 12 rotates around the first operating shaft 19 and interlocks with the first operating piece 16 connected to the operating lever 11. Rotates around the first actuating shaft 19. As a result, the pulling rod 21 connected to the first actuating piece 16 is pulled up. When the pulling rod 21 is pulled up, a pair of wedge-shaped brakes 22 included in the emergency stop device 2 are pulled up. The emergency stop device 2 in the first embodiment is based on a known technique.
　上述のように操作レバー１１が回動すると、操作レバー１１に接続されるアマチュア３４は、操作レバー１１の回動方向に沿って移動する。このため、電動操作器を待機状態に復帰させるためには、次に述べるように、電動操作器が備える復帰機構部（３６，３７，４１，４２）によって、アマチュア３４を移動位置から待機時の位置（図３参照）に戻す。 When the operation lever 11 rotates as described above, the amateur 34 connected to the operation lever 11 moves along the rotation direction of the operation lever 11. Therefore, in order to return the electric actuator to the standby state, as described below, the return mechanism unit (36, 37, 41, 42) provided in the electric actuator allows the amateur 34 to move from the moving position to the standby state. Return to position (see Figure 3).
　電動操作器は、アマチュア３４を駆動するために、図示しない基板もしくは台座の平面部上に位置する送りネジ３６を有する。送りネジ３６は、図示しない基板もしくは台座の平面上に固定される第１の支持部材４１および第２の支持部材４２によって回転可能に支持される。電磁石３５は、ネジ孔を有するネジ孔部材を備えており、このネジ孔部材が送りネジ３６と螺合する。送りネジ３６は、モータ３７によって回転される。 The electric actuator has a feed screw 36 located on a flat surface portion of a substrate or a pedestal (not shown) for driving the amateur 34. The lead screw 36 is rotatably supported by a first support member 41 and a second support member 42 fixed on a flat surface of a substrate or a pedestal (not shown). The electromagnet 35 includes a screw hole member having a screw hole, and this screw hole member is screwed with the feed screw 36. The lead screw 36 is rotated by a motor 37.
　回転する送りネジと電磁石３５が備えるネジ孔部材とによって、モータ３７の回転が、送りネジ３６の軸方向に沿った電磁石３５の直線的移動に変換される。これにより、後述するように（図３）、電磁石３５を移動してアマチュア３４を電磁石３５に吸着した後、電磁石３５を移動すれば、アマチュア３４を移動することができる。 The rotation of the motor 37 is converted into the linear movement of the electromagnet 35 along the axial direction of the feed screw 36 by the rotating feed screw and the screw hole member included in the electromagnet 35. As a result, as will be described later (FIG. 3), if the electromagnet 35 is moved to attract the amateur 34 to the electromagnet 35 and then the electromagnet 35 is moved, the amateur 34 can be moved.
　図３および図４は、本実施例１における電動操作器の動作を示す要部構成図である。図３は、待機時および動作後の電動操作器の状態を示す。また、図４は、待機状態に復帰中の電動操作器の状態を示す。 3 and 4 are configuration diagrams of main parts showing the operation of the electric actuator in the first embodiment. FIG. 3 shows the state of the electric actuator during standby and after operation. Further, FIG. 4 shows the state of the electric actuator during the return to the standby state.
　上述のように、図示しない安全制御装置からの指令により、電磁石３５の励磁が停止されると、図３に示すように、操作レバー１１が第１の作動軸１９の回りに、図中、時計回りに回転する。作動片１６も、第１の作動軸１９の回りに、図中、時計回りに、すなわち制動子（図２中の「２２」）を引き上げる方向に回転する。 As described above, when the excitation of the electromagnet 35 is stopped by a command from a safety control device (not shown), the operating lever 11 is rotated around the first operating shaft 19 as shown in FIG. Rotate around. The actuating piece 16 also rotates around the first actuating shaft 19 clockwise in the figure, that is, in the direction of pulling up the brake (“22” in FIG. 2).
　操作レバー１１の回転に伴い、アマチュア３４は、待機時の位置（実線）から動作後の位置（破線）へ移動する。このとき、アマチュア３４は、アマチュア３４の自重により、ローラ３９が長孔６０の下端部に接した状態で移動する。また、アマチュア３４は、電磁石３５には吸着されず、かつ復帰機構部（３６，３７，４１，４２）からは機械的に自由な状態であるため、復帰機構部、特に送りねじ３６には、負荷をかけない。これにより、アマチュア３４はスムースに移動する。また、アマチュア３４の移動に伴い復帰機構部に応力が発生することが防止される。したがって、電動操作器の動作の信頼性が向上する。 As the operation lever 11 rotates, the amateur 34 moves from the standby position (solid line) to the post-operation position (broken line). At this time, the amateur 34 moves in a state where the roller 39 is in contact with the lower end portion of the elongated hole 60 due to the weight of the amateur 34. Further, since the amateur 34 is not attracted to the electromagnet 35 and is mechanically free from the return mechanism portion (36, 37, 41, 42), the return mechanism portion, particularly the feed screw 36, is in a state of being mechanically free. No load is applied. As a result, the amateur 34 moves smoothly. Further, it is prevented that stress is generated in the return mechanism portion due to the movement of the amateur 34. Therefore, the reliability of the operation of the electric actuator is improved.
　なお、図３では、操作レバー１１および作動片１６についても、待機時の位置（実線）および動作後の位置（破線）を示している。電磁石３５は、復帰動作のためにモータ３７が回転を開始するまで、待機時の位置に留まる。 Note that FIG. 3 also shows the standby position (solid line) and the post-operation position (dashed line) of the operation lever 11 and the operating piece 16. The electromagnet 35 remains in the standby position until the motor 37 starts rotating for the return operation.
　待機時では、アマチュア３４は電磁石３５に吸着されているので、アマチュア３４の吸着面と電磁石３５の吸着面は互いに平行である。さらに、図３においては、動作後においても、動作後の位置におけるアマチュア３４（破線）の吸着面と、待機時の位置に留まる電磁石３５の吸着面は、互いに平行である。 Since the amateur 34 is attracted to the electromagnet 35 during standby, the suction surface of the amateur 34 and the suction surface of the electromagnet 35 are parallel to each other. Further, in FIG. 3, even after the operation, the suction surface of the amateur 34 (broken line) at the position after the operation and the suction surface of the electromagnet 35 staying at the standby position are parallel to each other.
　ここで、アマチュア３４は、待機時の位置から動作後の位置へ移動するときに、自重によりローラ３９の回りに回動してもよい。この場合、動作後において、アマチュア３４の吸着面と、待機時の位置に留まる電磁石３５の吸着面は、非平行となる。ただし、復帰機構により電磁石３５が移動してアマチュア３４を吸着すると、アマチュア３４は電磁力によってローラ３９の回りに回動するので、アマチュア３４の吸着面と、電磁石３５の吸着面は、待機時と同様に平行となる。すなわち、アマチュア３４の状態は、図３に示す状態（破線）となる。 Here, the amateur 34 may rotate around the roller 39 due to its own weight when moving from the standby position to the post-operation position. In this case, after the operation, the suction surface of the amateur 34 and the suction surface of the electromagnet 35 that stays in the standby position are not parallel to each other. However, when the electromagnet 35 moves by the return mechanism and attracts the amateur 34, the amateur 34 rotates around the roller 39 by the electromagnetic force, so that the suction surface of the amateur 34 and the suction surface of the electromagnet 35 are in standby mode. It will be parallel as well. That is, the state of the amateur 34 is the state (broken line) shown in FIG.
　モータ３７が回転すると、送りネジ３６によって、電磁石３５がアマチュア３４に向かって直線的に移動する。電磁石３５は、動作後のアマチュア３４の位置まで移動すると、アマチュア３４を電磁力で吸着する。電磁石３５がアマチュア３４を吸着した後、モータ３７が逆転すると、送りねじ３６によって、電磁石３５は、アマチュア３４を吸着したまま、待機時の位置に移動する。これにより、アマチュア３４は、待機時の位置に移動する。なお、本実施例１ではモータ３７の回転開始とともに、電磁石３５の励磁が再開されるが、これに限らず、電磁石３５がアマチュア３４の動作後の位置に到達する直前もしくは直後に励磁が再開されてもよい。 When the motor 37 rotates, the electromagnet 35 moves linearly toward the amateur 34 by the lead screw 36. When the electromagnet 35 moves to the position of the amateur 34 after the operation, the electromagnet 35 attracts the amateur 34 by an electromagnetic force. When the motor 37 reverses after the electromagnet 35 attracts the amateur 34, the lead screw 36 moves the electromagnet 35 to the standby position while attracting the amateur 34. As a result, the amateur 34 moves to the standby position. In the first embodiment, the excitation of the electromagnet 35 is restarted with the start of rotation of the motor 37, but the excitation is not limited to this, and the excitation is restarted immediately before or immediately after the electromagnet 35 reaches the position after the operation of the amateur 34. You may.
　上述のように、アマチュア３４は、待機時の位置から動作後の位置まで、ローラ３９が長孔６０の下端部に接した状態で移動するので、図３に示すように、動作後において、ローラ３９は、長孔６０の下端部に接する。さらに、本実施例１では、図３に示すように、待機時においても、ローラ３９は、長孔６０の下端部に接している。さらに、復帰動作中、長孔６０の下端部はローラ３９の下方に移動する（図４参照）。 As described above, the amateur 34 moves from the standby position to the post-operation position with the roller 39 in contact with the lower end of the elongated hole 60. Therefore, as shown in FIG. 3, the roller 39 moves after the operation. 39 is in contact with the lower end of the elongated hole 60. Further, in the first embodiment, as shown in FIG. 3, the roller 39 is in contact with the lower end portion of the elongated hole 60 even during standby. Further, during the return operation, the lower end portion of the elongated hole 60 moves below the roller 39 (see FIG. 4).
　したがって、第１の支持部材４１および第２の支持部材４２の設置平面からの、ローラ３９の高さは、復帰動作中は同じ高さｈに保たれる。このとき、送りネジ３６の長手方向すなわち回転軸方向は第１および第２の支持部材４１，４２の設置平面に平行であるから、送りネジ３６とローラ３９との距離が一定に保たれる。このため、比較例（長孔６０を有さない操作レバー）のローラが押し下げられる（図４参照）のに対し、本実施例１のローラ３９は、操作レバー１１によって押し上げられたり押し下げられたりはしない。したがって、復帰動作中、操作レバー１１およびアマチュア３４によって、アマチュア３４を吸着する電磁石３５を介して、復帰機構部、特に送りねじ３６に、負荷がかかることが防止される。 Therefore, the height of the roller 39 from the installation plane of the first support member 41 and the second support member 42 is maintained at the same height h during the return operation. At this time, since the longitudinal direction of the lead screw 36, that is, the direction of the axis of rotation is parallel to the installation planes of the first and second support members 41 and 42, the distance between the lead screw 36 and the roller 39 is kept constant. Therefore, the roller of the comparative example (the operation lever having no elongated hole 60) is pushed down (see FIG. 4), whereas the roller 39 of the first embodiment is pushed up or down by the operation lever 11. do not do. Therefore, during the return operation, the return mechanism portion, particularly the feed screw 36, is prevented from being loaded by the operation lever 11 and the amateur 34 via the electromagnet 35 that attracts the amateur 34.
　待機時において、長孔６０の下端部はローラ３９の下方に位置していてもよい。この場合でも、同様に、復帰動作中、復帰機構部に負荷がかかることが防止される。 During standby, the lower end of the elongated hole 60 may be located below the roller 39. Similarly, in this case as well, it is possible to prevent the return mechanism from being loaded during the return operation.
　なお、本実施例１のように、待機時においても、長孔６０の下端部がローラ３９に接する場合、電磁石３５が待機時の位置で励磁を停止された直後、アマチュア３４が自重によって動くとき、長孔６０の下端部の縁にローラ３９が当接する際の衝撃が低減される。また、復帰時におけるアマチュア３４の移動ストロークを大きくできるので、駆動ばね１３（図１）に蓄積される弾性エネルギーを大きくすることができる。 When the lower end of the elongated hole 60 is in contact with the roller 39 even during standby as in the first embodiment, when the amateur 34 moves by its own weight immediately after the electromagnet 35 is stopped at the standby position. The impact when the roller 39 comes into contact with the edge of the lower end of the elongated hole 60 is reduced. Further, since the moving stroke of the amateur 34 at the time of return can be increased, the elastic energy stored in the drive spring 13 (FIG. 1) can be increased.
　操作レバー１１は、長孔６０によって、アマチュア３４のローラ３９と摺動可能に接続されているので、図４に示すように、電動操作器１０の復帰動作中、長孔６０の下端部は、ローラ３９の下方に位置する。したがって、図４に示すように、復帰中、アマチュア３４が動作時の位置と待機時の位置との間に位置する時、ローラ３９は、長孔６０の上端部と下端部の間に位置する。すなわち、ローラ３９は、長孔６０の上端部および下端部の縁に接することなく、これらの縁から離れている。このため、機械的に接続される操作レバー１１およびアマチュア３４が、アマチュア３４を吸着する電磁石３５を介して、復帰機構部、特に送りねじ３６に、負荷がかかることが防止される。 Since the operating lever 11 is slidably connected to the roller 39 of the amateur 34 by the elongated hole 60, as shown in FIG. 4, during the return operation of the electric controller 10, the lower end portion of the elongated hole 60 is formed. It is located below the roller 39. Therefore, as shown in FIG. 4, when the amateur 34 is located between the operating position and the standby position during the return, the roller 39 is located between the upper end and the lower end of the elongated hole 60. .. That is, the roller 39 is separated from the edges of the upper and lower ends of the elongated holes 60 without touching them. Therefore, it is prevented that the operating lever 11 and the amateur 34, which are mechanically connected, are loaded on the return mechanism portion, particularly the feed screw 36, via the electromagnet 35 that attracts the amateur 34.
　これにより、電動操作器の復帰動作中、アマチュア３４はスムースに移動する。また、アマチュア３４の移動に伴い復帰機構部に応力が発生することが防止される。したがって、電動操作器の動作の信頼性が向上する。 As a result, the amateur 34 moves smoothly during the return operation of the electric actuator. Further, it is prevented that stress is generated in the return mechanism portion due to the movement of the amateur 34. Therefore, the reliability of the operation of the electric actuator is improved.
　本実施例１では、長孔６０の縁は、両端部が半円状、両端部間が直線状である。この半円の半径は、ローラ３９の半径に実質等しい。なお、半円の半径は、操作レバー１１が、長孔６０によって、ローラ３９に対して摺動可能に接続されるような大きさに設定される。そこで、本実施例１では、長孔６０の下端部の高さは、長孔６０の下端部の半円状の縁の中心の高さとしている。 In the first embodiment, the edge of the elongated hole 60 has a semicircular shape at both ends and a straight line between both ends. The radius of this semicircle is substantially equal to the radius of the roller 39. The radius of the semicircle is set so that the operating lever 11 is slidably connected to the roller 39 by the elongated hole 60. Therefore, in the first embodiment, the height of the lower end portion of the elongated hole 60 is set to the height of the center of the semicircular edge of the lower end portion of the elongated hole 60.
　ここで、長孔６０の上端部における半円の中心と長孔６０の下端部における半円の中心との距離を、長孔６０の長さＬとする。また、図４のように、操作レバー１１の長手方向と送りネジ３６の長手方向とが垂直になる場合における、長孔６０の下端部の半円の中心とローラ３９の中心との距離をＬ２とする。なお、本実施例１では、復帰動作中に、長孔６０の下端部における半円の中心とローラ３９の中心との距離が変化するが、Ｌ２は極大値である。本実施例１では、ＬとＬ２の間には、Ｌ≧Ｌ２の関係がある。これにより、復帰中のすべての時点で、復帰機構部に負荷がかかることが、確実に防止される。 Here, the distance between the center of the semicircle at the upper end of the elongated hole 60 and the center of the semicircle at the lower end of the elongated hole 60 is defined as the length L of the elongated hole 60. Further, as shown in FIG. 4, when the longitudinal direction of the operating lever 11 and the longitudinal direction of the lead screw 36 are perpendicular to each other, the distance between the center of the semicircle at the lower end of the elongated hole 60 and the center of the roller 39 is set to L. Let it be 2 . In the first embodiment, the distance between the center of the semicircle and the center of the roller 39 at the lower end of the elongated hole 60 changes during the return operation, but L 2 is a maximum value. In the first embodiment, there is a relationship of L ≧ L 2 between L and L 2 . As a result, it is surely prevented from applying a load to the return mechanism portion at all points during the return.
　また、図４のように、操作レバー１１の長手方向と送りネジ３６の長手方向とが垂直になる場合における、送りネジ３６の回転軸と長孔６０の下端部の半円の中心との距離をｌ１とし、送りネジ３６の回転軸とローラ３９の中心との距離をｌ２とすると、Ｌ２＝ｌ２－ｌ１であるから、Ｌ≧ｌ２－ｌ１の関係がある。 Further, as shown in FIG. 4, the distance between the rotation axis of the feed screw 36 and the center of the semicircle at the lower end of the elongated hole 60 when the longitudinal direction of the operation lever 11 and the longitudinal direction of the feed screw 36 are perpendicular to each other. If l 1 and the distance between the rotation axis of the lead screw 36 and the center of the roller 39 is l 2 , then L 2 = l 2 -l 1 , so there is a relationship of L ≧ l 2 -l 1 .
　なお、復帰動作中、アマチュア３４は電磁石３５に吸着されているので、送りネジ３６の回転軸とローラ３９の中心との距離は不変（ｌ２）である。また、操作レバー１１が第１の作動軸１９の回りに回動するので、送りネジ３６の回転軸と長孔６０の下端部の半円の中心との距離は変化し、図４のように、操作レバー１１の長手方向と送りネジ３６の長手方向とが垂直になる場合に、極小値ｌ１となる。 Since the amateur 34 is attracted to the electromagnet 35 during the return operation, the distance between the rotation axis of the feed screw 36 and the center of the roller 39 does not change (l 2 ). Further, since the operating lever 11 rotates around the first operating shaft 19, the distance between the rotating shaft of the feed screw 36 and the center of the semicircle at the lower end of the elongated hole 60 changes, as shown in FIG. When the longitudinal direction of the operating lever 11 and the longitudinal direction of the lead screw 36 are perpendicular to each other, the minimum value is l1.
　次に、本実施例１の構成の細部について、図５および図６を用いて説明しておく。 Next, the details of the configuration of the first embodiment will be described with reference to FIGS. 5 and 6.
　図５は、本実施例１における電動操作器の構成を示す側面図である。また、図６は、本実施例１における電動操作器の構成を示す平面図である。 FIG. 5 is a side view showing the configuration of the electric actuator in the first embodiment. Further, FIG. 6 is a plan view showing the configuration of the electric actuator in the first embodiment.
　なお、図５は、図４において、Ａ方向に向かって電動操作器を見た場合の構成を示す。また、図６は、図４において、上方から電動操作器を見た場合の構成を示す
　２個の円形のアマチュア３４と、２個の円形の電磁石３５とが、操作レバー１１の左右に、操作レバー１１を対称軸として、線対称に配置される。アマチュア３４の直径は電磁石３５の直径よりも大きく、アマチュア３４の円形の縁と電磁石３５の円形の縁とが同心円となるように、電磁石３５の円形平面およびアマチュア３４の円形平面とが配置される。このため、電磁石３５の円形平面の全体が、アマチュア３４の円形平面とオーバーラップしているので、アマチュア３４は、電磁石３５によって確実に吸着される。 Note that FIG. 5 shows the configuration when the electric actuator is viewed in the A direction in FIG. Further, FIG. 6 shows that the two circular amateurs 34 and the two circular electromagnets 35, which show the configuration when the electric controller is viewed from above in FIG. 4, are operated to the left and right of the operation lever 11. It is arranged line-symmetrically with the lever 11 as the axis of symmetry. The diameter of the amateur 34 is larger than the diameter of the electromagnet 35, and the circular plane of the electromagnet 35 and the circular plane of the amateur 34 are arranged so that the circular edge of the amateur 34 and the circular edge of the electromagnet 35 are concentric circles. .. Therefore, since the entire circular plane of the electromagnet 35 overlaps with the circular plane of the amateur 34, the amateur 34 is surely attracted by the electromagnet 35.
　２個の電磁石３５は、ネジ孔７１を有する矩形状のネジ孔部材７０の長手方向の両端部に固定され、ネジ孔部材７０によって互いに連結されている。ネジ孔７１は、ネジ孔部材７０の長手方向の中央部に位置し、送りネジ３６と螺合する。なお、２個のアマチュア３４は、ネジ孔部材７０の長手方向で、互いに接することなく離れて配置される。また、２個のアマチュア３４は、送りネジ３６に接することなく、送りネジ３６から離して配置される。また、２個の電磁石３５も、同様に、互いに離れて配置されるとともに、送りネジ３６から離して配置される。 The two electromagnets 35 are fixed to both ends in the longitudinal direction of the rectangular screw hole member 70 having the screw hole 71, and are connected to each other by the screw hole member 70. The screw hole 71 is located at the center of the screw hole member 70 in the longitudinal direction and is screwed with the feed screw 36. The two amateurs 34 are arranged apart from each other in the longitudinal direction of the screw hole member 70 without touching each other. Further, the two amateurs 34 are arranged apart from the lead screw 36 without being in contact with the lead screw 36. Similarly, the two electromagnets 35 are also arranged apart from each other and separated from the feed screw 36.
　アマチュア３４を支持するアマチュアブラケット３８における操作レバー接続部３３は、アマチュア３４の円形面から上方に突出し、さらに、操作レバー１１に向かって直角に折れ曲がり、さらに操作レバー１１に接する端部が上方に直角に折れ曲がる。２個の操作レバー接続部３３は、操作レバー１１を対称軸として、線対称に配置される。操作レバー１１は、２個の操作レバー接続部３３の間に位置する。ローラ３９は、２個の操作レバー接続部３３の端部と固定的に嵌合するとともに、２個の操作レバー接続部３３の間に位置する操作レバー１１の長孔６０を貫通する。 The operation lever connection portion 33 in the amateur bracket 38 that supports the amateur 34 projects upward from the circular surface of the amateur 34, further bends at a right angle toward the operation lever 11, and the end portion in contact with the operation lever 11 is at a right angle upward. It bends to. The two operating lever connecting portions 33 are arranged line-symmetrically with the operating lever 11 as the axis of symmetry. The operating lever 11 is located between the two operating lever connecting portions 33. The roller 39 is fixedly fitted to the ends of the two operating lever connecting portions 33, and penetrates the elongated hole 60 of the operating lever 11 located between the two operating lever connecting portions 33.
　図５および図６に示すように、アマチュア３４は、送りネジ３６、モータ３７、第１および第２の支持部４１，４２を含む復帰機構部とは、機械的には接続されていない。このため、アマチュア３４は、電磁石に吸着されていない場合、前述のように、復帰機構部からは機械的に自由な状態にある。 As shown in FIGS. 5 and 6, the amateur 34 is not mechanically connected to the return mechanism portion including the lead screw 36, the motor 37, and the first and second support portions 41 and 42. Therefore, when the amateur 34 is not attracted to the electromagnet, it is mechanically free from the return mechanism portion as described above.
　上述のように、本実施例１によれば、電動操作器の動作機構を複雑化することなく、電動操作器の動作の信頼性を向上できる。 As described above, according to the first embodiment, the reliability of the operation of the electric actuator can be improved without complicating the operation mechanism of the electric actuator.
　次に、本発明の実施例２であるエレベータ装置について、主に、実施例１と異なる点について説明する。 Next, the elevator device according to the second embodiment of the present invention will be mainly described as different from the first embodiment.
　本実施例２は、以下に説明するように、電動操作器の構成が実施例１とは異なる。 As described below, the second embodiment has a different configuration of the electric actuator from the first embodiment.
　図７および図８は、実施例２における電動操作器の動作を示す要部構成図である。図７は、待機時および動作後の電動操作器の状態を示す。また、図８は、待機状態に復帰中の電動操作器の状態を示す。 7 and 8 are configuration diagrams of main parts showing the operation of the electric actuator in the second embodiment. FIG. 7 shows the state of the electric actuator during standby and after operation. Further, FIG. 8 shows the state of the electric actuator during the return to the standby state.
　本実施例２においては、実施例１と異なり、操作レバー１１は、継手部６１を介して、アマチュア３４における操作レバー接続部３３に接続される。 In the second embodiment, unlike the first embodiment, the operating lever 11 is connected to the operating lever connecting portion 33 in the amateur 34 via the joint portion 61.
　操作レバー１１におけるアマチュア３４側の端部と、継手部６１の一端部とが、ローラ６２を介して接続される。したがって、継手部６１は、ローラ６２の回りに回動可能に、操作レバー１１と接続される。また、継手部６１の他端部と、アマチュア３４における操作レバー接続部３３とが、ローラ６３を介して接続される。したがって、継手部６１は、ローラ６３の回りに回動可能に、操作レバー接続部３３と接続される。 The end portion of the operation lever 11 on the amateur 34 side and one end portion of the joint portion 61 are connected via the roller 62. Therefore, the joint portion 61 is rotatably connected to the operating lever 11 around the roller 62. Further, the other end of the joint portion 61 and the operation lever connecting portion 33 in the amateur 34 are connected via the roller 63. Therefore, the joint portion 61 is rotatably connected to the operation lever connecting portion 33 around the roller 63.
　図示しない安全制御装置からの指令により、電磁石３５の励磁が停止されると、図７に示すように、操作レバー１１が第１の作動軸１９の回りに、図中、時計回りに回転する。作動片１６も、第１の作動軸１９の回りに、図中、時計回りに、すなわち制動子（図２中の「２２」）を引き上げる方向に回転する。 When the excitation of the electromagnet 35 is stopped by a command from a safety control device (not shown), the operating lever 11 rotates clockwise around the first operating shaft 19 as shown in FIG. 7. The actuating piece 16 also rotates around the first actuating shaft 19 clockwise in the figure, that is, in the direction of pulling up the brake (“22” in FIG. 2).
　操作レバー１１の回転に伴い、アマチュア３４は、待機時の位置（実線）から動作後の位置（破線）へ移動する。このとき、アマチュア３４の自重により、継手部６１の長手方向が鉛直方向に延びた状態で移動する。また、アマチュア３４は、電磁石３５には吸着されず、かつ復帰機構部（３６，３７，４１，４２）からは機械的に自由な状態であるため、復帰機構部、特に送りねじ３６には、負荷をかけない。これにより、アマチュア３４はスムースに移動する。また、アマチュア３４の移動に伴い復帰機構部に応力が発生することが防止される。したがって、電動操作器の動作の信頼性が向上する。 As the operation lever 11 rotates, the amateur 34 moves from the standby position (solid line) to the post-operation position (broken line). At this time, due to the weight of the amateur 34, the joint portion 61 moves in a state of being extended in the vertical direction. Further, since the amateur 34 is not attracted to the electromagnet 35 and is mechanically free from the return mechanism portion (36, 37, 41, 42), the return mechanism portion, particularly the feed screw 36, is in a state of being mechanically free. No load is applied. As a result, the amateur 34 moves smoothly. Further, it is prevented that stress is generated in the return mechanism portion due to the movement of the amateur 34. Therefore, the reliability of the operation of the electric actuator is improved.
　なお、図７では、操作レバー１１および作動片１６についても、待機時の位置（実線）および動作後の位置（破線）を示している。電磁石３５は、復帰動作のためにモータ３７が回転を開始するまで、待機時の位置に留まる。 Note that FIG. 7 also shows the standby position (solid line) and the post-operation position (dashed line) of the operation lever 11 and the operating piece 16. The electromagnet 35 remains in the standby position until the motor 37 starts rotating for the return operation.
　待機時では、アマチュア３４は電磁石３５に吸着されているので、アマチュア３４の吸着面と電磁石３５の吸着面は互いに平行である。さらに、図７においては、動作後においても、動作後の位置におけるアマチュア３４（破線）の吸着面と、待機時の位置に留まる電磁石３５の吸着面は、互いに平行である。 Since the amateur 34 is attracted to the electromagnet 35 during standby, the suction surface of the amateur 34 and the suction surface of the electromagnet 35 are parallel to each other. Further, in FIG. 7, even after the operation, the suction surface of the amateur 34 (broken line) at the position after the operation and the suction surface of the electromagnet 35 staying at the standby position are parallel to each other.
　ここで、アマチュア３４は、待機時の位置から動作後の位置へ移動するときに、自重によりローラ６３の回りに回動してもよい。この場合、動作後において、アマチュア３４の吸着面と、待機時の位置に留まる電磁石３５の吸着面は、非平行となる。ただし、復帰機構により電磁石３５が移動してアマチュア３４を吸着すると、アマチュア３４は電磁力によってローラ６３の回りに回動するので、アマチュア３４の吸着面と、電磁石３５の吸着面は、待機時と同様に平行となる。すなわち、アマチュア３４の状態は、図３に示す状態（破線）となる。 Here, the amateur 34 may rotate around the roller 63 due to its own weight when moving from the standby position to the post-operation position. In this case, after the operation, the suction surface of the amateur 34 and the suction surface of the electromagnet 35 that stays in the standby position are not parallel to each other. However, when the electromagnet 35 moves by the return mechanism and attracts the amateur 34, the amateur 34 rotates around the roller 63 by the electromagnetic force, so that the suction surface of the amateur 34 and the suction surface of the electromagnet 35 are in standby mode. It will be parallel as well. That is, the state of the amateur 34 is the state (broken line) shown in FIG.
　モータ３７が回転すると、送りネジ３６によって、電磁石３５がアマチュア３４に向かって直線的に移動する。電磁石３５は、動作後のアマチュア３４の位置まで移動すると、アマチュア３４を電磁力で吸着する。電磁石３５がアマチュア３４を吸着した後、モータ３７が逆転すると、送りねじ３６によって、電磁石３５は、アマチュア３４を吸着したまま、待機時の位置に移動する。これにより、アマチュア３４は、待機時の位置に移動する。 When the motor 37 rotates, the electromagnet 35 moves linearly toward the amateur 34 by the lead screw 36. When the electromagnet 35 moves to the position of the amateur 34 after the operation, the electromagnet 35 attracts the amateur 34 by an electromagnetic force. When the motor 37 reverses after the electromagnet 35 attracts the amateur 34, the lead screw 36 moves the electromagnet 35 to the standby position while attracting the amateur 34. As a result, the amateur 34 moves to the standby position.
　上述のように、アマチュア３４は、待機時の位置から動作後の位置まで、継手部６１の長手方向が鉛直方向に延びた状態で移動するので、図７に示すように、動作後において、継手部６１の長手方向が鉛直方向に延びた状態である。さらに、本実施例２では、図７に示すように、待機時においても、継手部６１の長手方向が鉛直方向に延びた状態である。さらに、復帰動作中、継手部６１は、ローラ６２，６３の回りに回動するので、アマチュア３４の移動に応じて、操作レバー１１の長手方向と継手部６１の長手方向とがなす角度が変化する（図８参照）。 As described above, the amateur 34 moves from the standby position to the post-operation position in a state where the longitudinal direction of the joint portion 61 extends in the vertical direction. Therefore, as shown in FIG. 7, the joint portion 61 moves after the operation. The longitudinal direction of the portion 61 extends in the vertical direction. Further, in the second embodiment, as shown in FIG. 7, the longitudinal direction of the joint portion 61 is extended in the vertical direction even during standby. Further, since the joint portion 61 rotates around the rollers 62 and 63 during the return operation, the angle formed by the longitudinal direction of the operating lever 11 and the longitudinal direction of the joint portion 61 changes according to the movement of the amateur 34. (See Fig. 8).
　したがって、第１の支持部材４１および第２の支持部材４２の設置平面からの、ローラ６３の高さは、復帰動作中は同じ高さｈに保たれる。このとき、送りネジ３６の長手方向すなわち回転軸方向は第１および第２の支持部材４１，４２の設置平面に平行であるから、送りネジ３６とローラ６３との距離が一定に保たれる。このため、図８に示すように、比較例（継手部６１を有さない操作レバー）のローラが押し下げられるのに対し、本実施例２のローラ６３は、操作レバー１１によって押し上げられたり押し下げられたりはしない。したがって、復帰動作中、操作レバー１１およびアマチュア３４によって、アマチュア３４を吸着する電磁石３５を介して、復帰機構部、特に送りねじ３６に、負荷がかかることが防止される。 Therefore, the height of the roller 63 from the installation plane of the first support member 41 and the second support member 42 is maintained at the same height h during the return operation. At this time, since the longitudinal direction of the lead screw 36, that is, the direction of the axis of rotation is parallel to the installation planes of the first and second support members 41 and 42, the distance between the lead screw 36 and the roller 63 is kept constant. Therefore, as shown in FIG. 8, the roller of the comparative example (the operation lever having no joint portion 61) is pushed down, whereas the roller 63 of the second embodiment is pushed up or down by the operation lever 11. I don't do it. Therefore, during the return operation, the return mechanism portion, particularly the feed screw 36, is prevented from being loaded by the operation lever 11 and the amateur 34 via the electromagnet 35 that attracts the amateur 34.
　待機時において、継手部６１の長手方向が鉛直方向に延びず、図８に示すように、継手部６１の長手方向と鉛直方向とが角度（＞０度）をなしていてもよい。この場合でも、同様に、復帰動作中、復帰機構部に負荷がかかることが防止される。 During standby, the longitudinal direction of the joint portion 61 does not extend in the vertical direction, and as shown in FIG. 8, the longitudinal direction and the vertical direction of the joint portion 61 may form an angle (> 0 degree). Similarly, in this case as well, it is possible to prevent the return mechanism from being loaded during the return operation.
　なお、本実施例２のように、待機時においても、継手部６１の長手方向が鉛直方向に延びた状態である場合、電磁石３５が待機時の位置で励磁を停止された直後、アマチュア３４が自重によって継手部６１がローラ６２の回りに回動するとき、アマチュア３４の振れが低減される。また、復帰時におけるアマチュア３４の移動ストロークを大きくできるので、駆動ばね１３（図１）に蓄積される弾性エネルギーを大きくすることができる。 In addition, as in the second embodiment, when the longitudinal direction of the joint portion 61 is extended in the vertical direction even in the standby state, the amateur 34 immediately after the electromagnet 35 is stopped to excite at the standby position. When the joint portion 61 rotates around the roller 62 due to its own weight, the runout of the amateur 34 is reduced. Further, since the moving stroke of the amateur 34 at the time of return can be increased, the elastic energy stored in the drive spring 13 (FIG. 1) can be increased.
　本実施例２においては、電動操作器１０の復帰動作中、操作レバー１１が第１の作動軸１９の回りに回動するので、ローラ６２の高さは変化するが、アマチュア３４の移動に応じて、操作レバー１１の長手方向と継手部６１の長手方向とがなす角度が変化するので、いわば、この角度変化によって、ローラ６２の高さの変化が吸収される。したがって、図８に示すように、復帰中、アマチュア３４が動作時の位置と待機時の位置との間に位置する時、ローラ６３の高さは、一定（図７の「ｈ」）に保たれる。このため、機械的に接続される操作レバー１１およびアマチュア３４が、アマチュア３４を吸着する電磁石３５を介して、復帰機構部、特に送りねじ３６に、負荷をかけることが防止される。 In the second embodiment, since the operating lever 11 rotates around the first operating shaft 19 during the returning operation of the electric controller 10, the height of the roller 62 changes, but it corresponds to the movement of the amateur 34. Therefore, the angle formed by the longitudinal direction of the operating lever 11 and the longitudinal direction of the joint portion 61 changes, so to speak, the change in the height of the roller 62 is absorbed by this angle change. Therefore, as shown in FIG. 8, the height of the roller 63 is kept constant (“h” in FIG. 7) when the amateur 34 is positioned between the operating position and the standby position during the return. Dripping. Therefore, the operating lever 11 and the amateur 34, which are mechanically connected, are prevented from applying a load to the return mechanism portion, particularly the feed screw 36, via the electromagnet 35 that attracts the amateur 34.
　これにより、電動操作器の復帰動作中、アマチュア３４はスムースに移動する。また、アマチュア３４の移動に伴い復帰機構部に応力が発生することが防止される。したがって、電動操作器の動作の信頼性が向上する。 As a result, the amateur 34 moves smoothly during the return operation of the electric actuator. Further, it is prevented that stress is generated in the return mechanism portion due to the movement of the amateur 34. Therefore, the reliability of the operation of the electric actuator is improved.
　ここで、ローラ６２の中心とローラ６３との距離を、継手部６１の長さＬとする。また、復帰動作中における、送りネジ３６の回転軸とローラ６２の中心との距離の極大値をｌ２とし、送りネジ３６の回転軸とローラ６３の中心との距離をｌ１とすると、Ｌ≧ｌ２－ｌ１の関係がある。これにより、復帰中のすべての時点で、復帰機構部に負荷がかかることが、確実に防止される。 Here, the distance between the center of the roller 62 and the roller 63 is defined as the length L of the joint portion 61. Further, assuming that the maximum value of the distance between the rotation axis of the lead screw 36 and the center of the roller 62 during the return operation is l 2 , and the distance between the rotation axis of the lead screw 36 and the center of the roller 63 is l 1 , L There is a relationship of ≧ l 2 − l 1 . As a result, it is surely prevented from applying a load to the return mechanism portion at all points during the return.
　なお、復帰動作中、アマチュア３４は電磁石３５に吸着されているので、送りネジ３６の回転軸とローラ６３の中心との距離は不変（ｌ１）である。また、操作レバー１１が第１の作動軸１９の回りに回動するので、ローラ６３の中心との距離は変化し、図７のように、操作レバー１１の長手方向と送りネジ３６の長手方向とが垂直になる場合に、極大値ｌ２となる。また、図７に示すように、送りねじ３６の回転軸の方向と継手部６１の長手方向とが垂直である場合、Ｌは最短となる。したがって、Ｌ≧ｌ２－ｌ１であれば、復帰動作中、操作レバー１１の長手方向と継手部６１の長手方向とがなす角度の変化によって、ローラ６２の高さの変化が吸収される。 Since the amateur 34 is attracted to the electromagnet 35 during the return operation, the distance between the rotation axis of the feed screw 36 and the center of the roller 63 does not change (l 1 ). Further, since the operating lever 11 rotates around the first operating shaft 19, the distance from the center of the roller 63 changes, and as shown in FIG. 7, the longitudinal direction of the operating lever 11 and the longitudinal direction of the feed screw 36 When and becomes vertical, the maximum value is l 2 . Further, as shown in FIG. 7, when the direction of the rotation axis of the lead screw 36 and the longitudinal direction of the joint portion 61 are perpendicular to each other, L is the shortest. Therefore, if L ≧ l 2 −l 1 , the change in the height of the roller 62 is absorbed by the change in the angle formed by the longitudinal direction of the operating lever 11 and the longitudinal direction of the joint portion 61 during the return operation.
　次に、本実施例２の構成の細部について、図９を用いて説明しておく。なお、実施例１（図５）と異なる点について説明する。 Next, the details of the configuration of the second embodiment will be described with reference to FIG. The points different from those of the first embodiment (FIG. 5) will be described.

　操作レバー１１の一端部の厚さが、操作レバー１１の厚さ方向の中央部において、一端部に続く部分よりも小さくなっている。また、継手部６１の一端部には、継手部６１の厚さ方向の中央部に、図中の奥行方向（操作レバー１１および継手部６１の幅方向）に貫通する溝が設けられる。このような操作レバー１１の一端部と継手部６１の一端部とが嵌め合わされた状態で、ローラ６２が操作レバー１１の一端部と継手部６１の一端部とを貫通している。 The thickness of one end of the operating lever 11 is smaller in the central portion in the thickness direction of the operating lever 11 than the portion following the one end. Further, one end of the joint portion 61 is provided with a groove penetrating in the depth direction (width direction of the operation lever 11 and the joint portion 61) in the drawing at the center portion in the thickness direction of the joint portion 61. The roller 62 penetrates one end of the operation lever 11 and one end of the joint 61 in a state where one end of the operation lever 11 and one end of the joint 61 are fitted to each other.
　ローラ６３は、２個の操作レバー接続部３３の端部と固定的に嵌合するとともに、２個の操作レバー接続部３３の間に位置する継手部６１の他端部を貫通する。 The roller 63 is fixedly fitted to the ends of the two operating lever connecting portions 33, and penetrates the other end of the joint portion 61 located between the two operating lever connecting portions 33.
