続いて、添付した図面を参照しつつ、本発明を具体化した実施の形態につき説明し、本発明の理解に供する。
図１に示すように、本発明の第１の実施の形態に係る水門開閉装置１０は、駆動源１１及び駆動源１１の回転力が与えられて出力部の一例である太陽歯車１２が回転駆動する動力伝達機構１３を有し、太陽歯車１２の回転駆動に応じた速度で水門の扉体Ｇを昇降する装置である。 Subsequently, an embodiment embodying the present invention will be described with reference to the attached drawings, and the present invention will be understood.
As shown in FIG. 1, in the floodgate opening / closing device 10 according to the first embodiment of the present invention, the drive source 11 and the solar gear 12 which is an example of the output unit are rotationally driven by the rotational force of the drive source 11. It is a device having a power transmission mechanism 13 for raising and lowering the door body G of the floodgate at a speed corresponding to the rotational drive of the sun gear 12.

水門開閉装置１０は、図１に示すように、駆動源１１が主としてモータ１４（第１のモータ）及びモータ１５（第２のモータ）から構成されている。即ち、駆動源１１は第１、第２のモータを具備している。モータ１４はＴ１方向及びＴ２方向（Ｔ１方向の逆方向）に回転可能であり、モータ１５はＲ１方向及びＲ２方向（Ｒ１方向の逆方向）に回転可能である。モータ１４、１５は共に、モータ１４、１５に接続された制御部１６から指令信号が送信されて回転方向が切り替えられる。 As shown in FIG. 1, in the water gate opening / closing device 10, the drive source 11 is mainly composed of a motor 14 (first motor) and a motor 15 (second motor). That is, the drive source 11 includes first and second motors. The motor 14 can rotate in the T1 direction and the T2 direction (reverse direction of the T1 direction), and the motor 15 can rotate in the R1 direction and the R2 direction (reverse direction of the R1 direction). Both the motors 14 and 15 are switched in the rotation direction by transmitting a command signal from the control unit 16 connected to the motors 14 and 15.

モータ１４のＴ１方向の回転及びＴ２方向の回転は、回転速度が等しく、回転速度が固定されている。モータ１５のＲ１方向の回転及びＲ２方向の回転も、回転速度が等しく、回転速度が固定されている。
なお、本実施の形態では、Ｔ１方向及びＲ１方向が時計回りの方向を意味し、Ｔ２方向及びＲ２方向が反時計回りの方向を意味するが、これに限定されず、例えば、Ｔ１方向及びＲ２方向が時計回りの方向で、Ｔ２方向及びＲ１方向が反時計回りの方向であってもよい。
また、本実施の形態では、モータ１４の回転速度とモータ１５の回転速度は異なるが、同じであってもよい。 The rotation speed of the motor 14 in the T1 direction and the rotation in the T2 direction are the same, and the rotation speed is fixed. The rotation speed of the motor 15 in the R1 direction and the rotation in the R2 direction are also the same, and the rotation speed is fixed.
In the present embodiment, the T1 direction and the R1 direction mean the clockwise direction, and the T2 direction and the R2 direction mean the counterclockwise direction, but the present invention is not limited to this, and for example, the T1 direction and the R2 direction. The direction may be a clockwise direction, and the T2 direction and the R1 direction may be a counterclockwise direction.
Further, in the present embodiment, the rotation speed of the motor 14 and the rotation speed of the motor 15 are different, but may be the same.

本実施の形態において、動力伝達機構１３は、遊星歯車機構であり、モータ１４に対応する入力部Ｐの一例である内歯車１７と、内歯車１７に噛み合った遊星歯車１８と、モータ１５に対応する入力部Ｑの一例である遊星キャリア２３と、内歯車１７と同心に配された太陽歯車１２とを備えている。
内歯車１７の外周には外周歯１９が取り付けられ、外周歯１９には、モータ１４の出力軸２０に連結された歯車２１が噛み合っている。そのため、モータ１４（モータ１４の出力軸２０）の回転力は歯車２１を介して内歯車１７に伝えられ、内歯車１７が一方向又は他方向に回転する。なお、本実施の形態において、一方向の回転及び他方向の回転とは時計回りの回転及び反時計回りの回転をそれぞれ意味する。 In the present embodiment, the power transmission mechanism 13 is a planetary gear mechanism, and corresponds to the internal gear 17 which is an example of the input unit P corresponding to the motor 14, the planetary gear 18 meshed with the internal gear 17, and the motor 15. It includes a planetary carrier 23, which is an example of the input unit Q, and a sun gear 12 arranged concentrically with the internal gear 17.
Outer peripheral teeth 19 are attached to the outer periphery of the internal gear 17, and gears 21 connected to the output shaft 20 of the motor 14 mesh with the outer peripheral teeth 19. Therefore, the rotational force of the motor 14 (the output shaft 20 of the motor 14) is transmitted to the internal gear 17 via the gear 21, and the internal gear 17 rotates in one direction or the other direction. In the present embodiment, rotation in one direction and rotation in the other direction mean clockwise rotation and counterclockwise rotation, respectively.

遊星歯車１８は複数（本実施の形態では４個）あって、各遊星歯車１８は、内歯車１７の内歯２２及び太陽歯車１２に噛み合った状態であり、自転と太陽歯車１２を中心とした公転とが可能である。複数の遊星歯車１８には、各遊星歯車１８を回転自在に支持する遊星キャリア２３が接続され、遊星キャリア２３には遊星キャリア軸２４が連結されている。モータ１５の出力軸２５と遊星キャリア軸２４の間にはクラッチ２６が設けられ、出力軸２５と遊星キャリア軸２４は、クラッチ２６によって、連結状態及び非連結状態が切り替えられる。出力軸２５が遊星キャリア軸２４に連結された状態でモータ１５を作動させることにより、各遊星歯車１８は一方向又は他方向に自転しながら太陽歯車１２を中心に公転する。 There are a plurality of planetary gears 18 (4 in this embodiment), and each planetary gear 18 is in a state of being meshed with the internal teeth 22 of the internal gear 17 and the sun gear 12, and is centered on the rotation and the sun gear 12. Revolution is possible. A planetary carrier 23 that rotatably supports each planetary gear 18 is connected to the plurality of planetary gears 18, and a planetary carrier shaft 24 is connected to the planetary carrier 23. A clutch 26 is provided between the output shaft 25 of the motor 15 and the planet carrier shaft 24, and the output shaft 25 and the planet carrier shaft 24 are switched between a connected state and a non-connected state by the clutch 26. By operating the motor 15 with the output shaft 25 connected to the planet carrier shaft 24, each planetary gear 18 revolves around the sun gear 12 while rotating in one direction or the other direction.

遊星キャリア２３の近傍には、遊星キャリア２３を固定して各遊星歯車１８が太陽歯車１２中心の公転をできないようにするブレーキ２７が設けられている。クラッチ２６及びブレーキ２７の各動作は、クラッチ２６及びブレーキ２７に接続された制御部１６によって制御される。
太陽歯車１２の中心には、太陽歯車１２の軸心に沿った軸材２８が連結され、軸材２８はギア２９に噛み合ったギア３０の中心に連結されている。 In the vicinity of the planetary carrier 23, a brake 27 is provided which fixes the planetary carrier 23 and prevents each planetary gear 18 from revolving around the center of the sun gear 12. Each operation of the clutch 26 and the brake 27 is controlled by a control unit 16 connected to the clutch 26 and the brake 27.
A shaft member 28 along the axis of the sun gear 12 is connected to the center of the sun gear 12, and the shaft member 28 is connected to the center of the gear 30 meshed with the gear 29.

ギア２９の中心に一端部が連結された軸材３１の他端部にはスプロケット３２の中心が連結され、スプロケット３２には、扉体Ｇに接続されたチェーン３３が掛け渡されている。ギア２９の径はギア３０の径より大きく、ギア２９、３０によって減速機が構成されている。ギア２９、３０及びスプロケット３２は、太陽歯車１２の回転駆動に伴って回転駆動し、扉体Ｇはスプロケット３２の回転によって昇降する。
なお、本発明には直接的な関係がないことから、記載を省略しているが、この種の水門開閉装置の実際の設計に当たっては、ギア２９、３０により構成された減速機以外の減速機や、ウォームギアにより構成されるセルフロック機構等が設けられる。 The center of the sprocket 32 is connected to the other end of the shaft member 31 whose one end is connected to the center of the gear 29, and the chain 33 connected to the door body G is hung on the sprocket 32. The diameter of the gear 29 is larger than the diameter of the gear 30, and the gears 29 and 30 constitute a reduction gear. The gears 29 and 30 and the sprocket 32 are rotationally driven by the rotational drive of the sun gear 12, and the door body G is moved up and down by the rotation of the sprocket 32.
Since there is no direct relationship with the present invention, the description is omitted, but in the actual design of this type of water gate opening / closing device, a speed reducer other than the speed reducer composed of gears 29 and 30 is used. Also, a self-locking mechanism composed of worm gears and the like are provided.

次に、扉体Ｇを下降させる際及び上昇させる際の動作について説明する。
扉体Ｇを下降させる際、ブレーキ２７を非作動にして各遊星歯車１８を公転可能な状態にし、クラッチ２６でモータ１５の出力軸２５を遊星キャリア軸２４に連結した状態にして、モータ１４、１５（モータ１４の出力軸２０及びモータ１５の出力軸２５）をそれぞれＴ１方向及びＲ１方向に回転させる。 Next, the operation when lowering and raising the door body G will be described.
When lowering the door body G, the brake 27 is deactivated so that each planetary gear 18 can revolve, and the output shaft 25 of the motor 15 is connected to the planet carrier shaft 24 by the clutch 26. 15 (the output shaft 20 of the motor 14 and the output shaft 25 of the motor 15) is rotated in the T1 direction and the R1 direction, respectively.

これによって、Ｔ１方向に回転しているモータ１４の回転力が歯車２１経由で内歯車１７に入力され、Ｒ１方向に回転しているモータ１５の回転力が遊星キャリア軸２４及び遊星キャリア２３経由で各遊星歯車１８に入力されることから、内歯車１７は、図２（Ａ）に示すように、他方向に回転駆動し、各遊星歯車１８は他方向に自転しながら太陽歯車１２を中心に一方向に公転し、太陽歯車１２が回転数Ｓ１で一方向に回転駆動する。その結果、スプロケット３２が他方向に回転駆動して、扉体Ｇが下降する。 As a result, the rotational force of the motor 14 rotating in the T1 direction is input to the internal gear 17 via the gear 21, and the rotational force of the motor 15 rotating in the R1 direction is transmitted via the planetary carrier shaft 24 and the planetary carrier 23. Since it is input to each planetary gear 18, the internal gear 17 is rotationally driven in the other direction as shown in FIG. 2 (A), and each planetary gear 18 rotates around the sun gear 12 while rotating in the other direction. It revolves in one direction, and the sun gear 12 is rotationally driven in one direction at the rotation speed S1. As a result, the sprocket 32 is rotationally driven in the other direction, and the door body G is lowered.

一方、扉体Ｇを上昇させる際には、ブレーキ２７を作動して各遊星歯車１８を公転不可能な状態にし、クラッチ２６でモータ１５の出力軸２５を遊星キャリア軸２４に対し非連結な状態にし、モータ１５を停止した状態（モータ１５の回転力が遊星歯車１８に非入力の状態）で、モータ１４をＴ２方向に回転させる。これにより、Ｔ２方向に回転しているモータ１４の回転力が内歯車１７に入力されて、図２（Ｂ）に示すように、内歯車１７は一方向に回転駆動し、各遊星歯車１８は公転せず一方向に自転し、太陽歯車１２は回転数Ｓ１より小さい回転数Ｓ２で他方向に回転駆動する。その結果、スプロケット３２が一方向に回転駆動して、扉体Ｇは上昇する。なお、回転数Ｓ１、Ｓ２の「回転数」とは、単位時間当たりの回転数を意味する。 On the other hand, when raising the door body G, the brake 27 is operated to make each planetary gear 18 unable to revolve, and the output shaft 25 of the motor 15 is not connected to the planetary carrier shaft 24 by the clutch 26. Then, the motor 14 is rotated in the T2 direction in a state where the motor 15 is stopped (a state in which the rotational force of the motor 15 is not input to the planetary gear 18). As a result, the rotational force of the motor 14 rotating in the T2 direction is input to the internal gear 17, and as shown in FIG. 2B, the internal gear 17 is rotationally driven in one direction, and each planetary gear 18 is driven. It rotates in one direction without revolving, and the sun gear 12 is rotationally driven in the other direction at a rotation speed S2 smaller than the rotation speed S1. As a result, the sprocket 32 is rotationally driven in one direction, and the door body G rises. The "rotation speed" of the rotation speeds S1 and S2 means the rotation speed per unit time.

ここで、扉体Ｇの下降時には、モータ１４の回転力が与えられている内歯車１７の回転と、モータ１５の回転力が与えられている遊星キャリア２３（各遊星歯車１８の自転及び公転）とが合わさって、太陽歯車１２が一方向に回転駆動する。即ち、動力伝達機構１３は、モータ１４、１５の各回転力が入力されて、太陽歯車１２が回転駆動する。 Here, when the door body G is lowered, the rotation of the internal gear 17 to which the rotational force of the motor 14 is applied and the planetary carrier 23 to which the rotational force of the motor 15 is applied (rotation and revolution of each planetary gear 18). Together with, the sun gear 12 is rotationally driven in one direction. That is, the power transmission mechanism 13 is input with the rotational forces of the motors 14 and 15, and the sun gear 12 is rotationally driven.

これに対し、扉体Ｇの上昇時、モータ１５の回転力が遊星キャリア２３（各遊星歯車１８）に与えられていない状態で、モータ１４の回転力が内歯車１７に与えられることによって、内歯車１７の回転駆動が各遊星歯車１８の自転により太陽歯車１２に伝わり、太陽歯車１２が他方向に回転駆動する。即ち、動力伝達機構１３は、モータ１４の回転力のみが入力されて、太陽歯車１２が回転駆動する。
従って、太陽歯車１２が他方向に回転駆動する回転数Ｓ２は、太陽歯車１２が一方向に回転駆動する回転数Ｓ１より小さくなる。従って、扉体Ｇの下降は扉体Ｇの上昇に比べて高速となる。 On the other hand, when the door body G rises, the rotational force of the motor 14 is applied to the internal gear 17 while the rotational force of the motor 15 is not applied to the planetary carrier 23 (each planetary gear 18). The rotational drive of the gear 17 is transmitted to the sun gear 12 by the rotation of each planetary gear 18, and the sun gear 12 is rotationally driven in the other direction. That is, in the power transmission mechanism 13, only the rotational force of the motor 14 is input, and the sun gear 12 is rotationally driven.
Therefore, the rotation number S2 in which the sun gear 12 is rotationally driven in the other direction is smaller than the rotation number S1 in which the solar gear 12 is rotationally driven in one direction. Therefore, the lowering of the door body G is faster than the rising of the door body G.

また、水門開閉装置１０は、駆動源が２つのモータ１４、１５を具備し、モータ１４、１５が共に時計回りの回転及び反時計周りの回転を行えることから、モータ１４、１５のいずれか一方が不具合により作動不可となっても、他方の作動によって扉体Ｇを昇降させることが可能である。 Further, since the water gate opening / closing device 10 includes two motors 14 and 15 as drive sources and both of the motors 14 and 15 can rotate clockwise and counterclockwise, any one of the motors 14 and 15 can be rotated. Even if the door body G cannot be operated due to a malfunction, the door body G can be raised and lowered by the other operation.

ここまで説明した水門開閉装置１０は、太陽歯車１２、内歯車１７及び遊星キャリア２３がそれぞれ出力部、入力部Ｐ及び入力部Ｑであるが、これに限定されない。
以下、図３、図４を参照して、遊星キャリア４１、内歯車１７及び太陽歯車４２がそれぞれ出力部、入力部Ｐ及び入力部Ｑである水門開閉装置４０について説明する。なお、水門開閉装置４０において、水門開閉装置１０と同様の構成については、同じ符号を付して詳しい説明を省略する。 In the water gate opening / closing device 10 described so far, the sun gear 12, the internal gear 17, and the planet carrier 23 are output units, input units P, and input units Q, respectively, but are not limited thereto.
Hereinafter, the floodgate opening / closing device 40 in which the planetary carrier 41, the internal gear 17, and the sun gear 42 are the output unit, the input unit P, and the input unit Q, respectively, will be described with reference to FIGS. 3 and 4. In the water gate opening / closing device 40, the same components as those of the water gate opening / closing device 10 are designated by the same reference numerals, and detailed description thereof will be omitted.

本発明の第２の実施の形態に係る水門開閉装置４０は、図３に示すように、駆動源１１の回転力が与えられて遊星キャリア４１（出力部）が回転駆動する動力伝達機構４３を有している。遊星歯車機構である動力伝達機構４３は、モータ１４に対応する内歯車１７（入力部Ｐ）、モータ１５に対応する太陽歯車４２（入力部Ｑ）、複数の遊星歯車１８、及び、各遊星歯車１８を回転自在に支持する遊星キャリア４１を備えている。 As shown in FIG. 3, the water gate opening / closing device 40 according to the second embodiment of the present invention provides a power transmission mechanism 43 in which the planetary carrier 41 (output unit) is rotationally driven by the rotational force of the drive source 11. Have. The power transmission mechanism 43, which is a planetary gear mechanism, includes an internal gear 17 (input unit P) corresponding to the motor 14, a sun gear 42 (input unit Q) corresponding to the motor 15, a plurality of planetary gears 18, and each planetary gear. It includes a planetary carrier 41 that rotatably supports 18.

モータ１５の出力軸２５と太陽歯車４２の中心に連結された軸材４４とは、出力軸２５及び軸材４４の間に設けられたクラッチ２６によって、連結状態及び非連結状態が切り替えられる。出力軸２５が軸材４４に連結された状態でモータ１５が作動することにより、太陽歯車４２は一方向又は他方向に回転する。太陽歯車４２には各遊星歯車１８が噛み合っている。太陽歯車４２の近傍には、制御部１６からの信号送信によって太陽歯車４２を固定するブレーキ４５が設けられている。
遊星キャリア４１、遊星キャリア４１に一端が連結され他端がギア３０に連結された遊星キャリア軸４６、ギア２９、３０、軸材３１及びスプロケット３２は、各遊星歯車１８が自転を伴い太陽歯車４２を中心に公転することによって回転する。 The output shaft 25 of the motor 15 and the shaft member 44 connected to the center of the sun gear 42 are switched between a connected state and a non-connected state by a clutch 26 provided between the output shaft 25 and the shaft member 44. When the motor 15 operates with the output shaft 25 connected to the shaft member 44, the sun gear 42 rotates in one direction or the other direction. Each planetary gear 18 meshes with the sun gear 42. A brake 45 for fixing the sun gear 42 by transmitting a signal from the control unit 16 is provided in the vicinity of the sun gear 42.
In the planetary carrier 41, the planetary carrier shaft 46, the gears 29, 30, the shaft member 31 and the sprocket 32 having one end connected to the planetary carrier 41 and the other end connected to the gear 30, each planetary gear 18 rotates and the sun gear 42 It rotates by revolving around.

扉体Ｇを下降させる際、ブレーキ４５を非作動にして太陽歯車４２を回転可能な状態にし、クラッチ２６でモータ１５の出力軸２５を軸材４４に連結した状態にして、モータ１４、１５をそれぞれＴ１方向及びＲ１方向に回転させる。これによって、内歯車１７及び太陽歯車４２は共に、図４（Ａ）に示すように、一方向に回転駆動し、各遊星歯車１８が自転しながら太陽歯車４２を中心に一方向に公転する。その結果、遊星キャリア４１及び遊星キャリア軸４６が回転数Ｓ１’で一方向に回転し、スプロケット３２が他方向に回転駆動して、扉体Ｇは下降する。本実施の形態では、Ｔ２方向及びＲ１方向が時計回りの方向を意味し、Ｔ１方向及びＲ２方向が反時計回りの方向を意味する。 When lowering the door body G, the brake 45 is deactivated to make the sun gear 42 rotatable, the output shaft 25 of the motor 15 is connected to the shaft member 44 by the clutch 26, and the motors 14 and 15 are moved. Rotate in the T1 direction and the R1 direction, respectively. As a result, both the internal gear 17 and the sun gear 42 are rotationally driven in one direction as shown in FIG. 4A, and each planetary gear 18 revolves in one direction around the sun gear 42 while rotating. As a result, the planetary carrier 41 and the planetary carrier shaft 46 rotate in one direction at the rotation speed S1', the sprocket 32 is rotationally driven in the other direction, and the door body G descends. In the present embodiment, the T2 direction and the R1 direction mean the clockwise direction, and the T1 direction and the R2 direction mean the counterclockwise direction.

扉体Ｇを上昇させる際、ブレーキ４５を作動して太陽歯車４２を回転不可能な状態にし、クラッチ２６でモータ１５の出力軸２５を軸材４４に非連結な状態にし、モータ１５を停止した状態で、モータ１４をＴ２方向に回転させる。これにより、内歯車１７は、図４（Ｂ）に示すように、他方向に回転駆動し、各遊星歯車１８が自転しながら貸与歯車４２を中心に他方向に公転する。その結果、遊星キャリア４１及び遊星キャリア軸４６が回転数Ｓ１’より小さい回転数Ｓ２’で他方向に回転し、スプロケット３２が一方向に回転駆動して、扉体Ｇは上昇する。 When raising the door body G, the brake 45 was activated to make the sun gear 42 non-rotatable, the output shaft 25 of the motor 15 was not connected to the shaft member 44 by the clutch 26, and the motor 15 was stopped. In this state, the motor 14 is rotated in the T2 direction. As a result, as shown in FIG. 4B, the internal gear 17 is rotationally driven in the other direction, and each planetary gear 18 revolves in the other direction around the loan gear 42 while rotating. As a result, the planetary carrier 41 and the planetary carrier shaft 46 rotate in the other direction at a rotation speed S2'smaller than the rotation speed S1', the sprocket 32 is rotationally driven in one direction, and the door body G rises.

扉体Ｇの下降時には、モータ１４の回転力が与えられている内歯車１７の回転と、モータ１５の回転力が与えられている太陽歯車４２の回転とが合わさって、遊星キャリア４１及び遊星キャリア軸４６が回転する。これに対し、扉体Ｇの上昇時、モータ１５の回転力が太陽歯車４２に与えられていない状態で、モータ１４の回転力が与えられている内歯車１７の回転のみによって、遊星キャリア４１及び遊星キャリア軸４６が回転する。従って、扉体Ｇの下降は扉体Ｇの上昇に比べて高速となる。 When the door body G is lowered, the rotation of the internal gear 17 to which the rotational force of the motor 14 is applied and the rotation of the sun gear 42 to which the rotational force of the motor 15 is applied are combined to form the planetary carrier 41 and the planetary carrier. The shaft 46 rotates. On the other hand, when the door body G rises, the planetary carrier 41 and the planetary carrier 41 and the planetary carrier 41 and The planetary carrier shaft 46 rotates. Therefore, the lowering of the door body G is faster than the rising of the door body G.

そして、動力伝達機構が遊星歯車機構である場合、内歯車を出力部とすることもできる。構造の簡素化の観点では、太陽歯車及び内歯車のいずれか一方を出力部とするのが好ましい。また、遊星歯車機構を減速機としても機能させる場合には、太陽歯車又は遊星キャリアのいずれか一方を出力部とするのが好ましい。 Further, the power transmission mechanism is not limited to the planetary gear mechanism, and may be, for example, a mechanism having a differential gear.
When the power transmission mechanism is a planetary gear mechanism, the internal gear can be used as an output unit. From the viewpoint of simplifying the structure, it is preferable to use either the sun gear or the internal gear as the output unit. Further, when the planetary gear mechanism also functions as a speed reducer, it is preferable that either the sun gear or the planetary carrier is used as the output unit.

また、扉体はチェーンに吊るされている必要は無く、例えば、ワイヤーであってもよい。扉体がワイヤーに吊るされている場合、出力部としてドラムが採用される。 Further, the door body does not need to be hung on the chain, and may be, for example, a wire. When the door body is hung on a wire, a drum is adopted as an output unit.
