Description

乗客コンベアPassenger conveyor
　本発明はエスカレータや電動道路等の乗客コンベアに係り、特に電動機と駆動スプロケットが同軸上に設置される駆動装置を備えた乗客コンベアに関する。 The present invention relates to a passenger conveyor such as an escalator or an electric road, and more particularly to a passenger conveyor provided with a driving device in which an electric motor and a driving sprocket are installed on the same axis.
　乗客コンベアであるエスカレータや電動道路等は、乗降口間を移動する無端状に連結されたステップ、或いはパレット(以下、代表して踏板という)と、この踏板の両側に設けられた欄干と、この欄干上を踏板と同期して移動する移動手摺とによって構成され、一方の乗降口から他方の乗降口までの間を移動する踏板で乗客を搬送するものである。 Passenger conveyors such as escalators and electric roads are connected to endlessly moving steps or pallets (hereinafter referred to as treads) and railings provided on both sides of the treads. It is composed of a moving handrail that moves on the railing in synchronization with the tread, and transports passengers with a tread that moves from one entrance to the other entrance.
　一般的に踏板は金属製のチェーンで連結され、チェーンは乗客コンベア上部の踏板反転装置に備えられた駆動スプロケットに巻き掛けられている。 Generally, the treads are connected by a metal chain, and the chain is wound around a drive sprocket provided in a tread board reversing device at the top of the passenger conveyor.
　駆動スプロケットに電動機からの動力を伝達する機構として、特表２０００－５０５４０６号公報（特許文献１）に記載されたものが知られている。特許文献１には、ステップスプロケット軸の一方の端部に固定された第一ステップスプロケットと、ステップスプロケット軸の他方の端部に固定された第二ステップスプロケットと、第二ステップスプロケットに取り付けられた回転子部品とを備え、ステップスプロケット軸の一方の端部が乗客コンベアの一方の側の支持構造物上に軸受によって据え付けられ、ステップスプロケット軸の他方の端部が軸受によって駆動モータの固定子に据え付けられた乗客コンベアの駆動装置が記載されている（第４図）。この駆動装置では、固定子は乗客コンベアの他方の側の支持構造物上に固定されており、ステップスプロケット軸の両端部は支持構造物に据え付けられた軸受、或いは支持構造物に固定された固定子に据え付けられた軸受によって軸支されている。 As a mechanism for transmitting power from an electric motor to a drive sprocket, a mechanism described in JP 2000-505406 A (Patent Document 1) is known. In Patent Document 1, a first step sprocket fixed to one end of a step sprocket shaft, a second step sprocket fixed to the other end of the step sprocket shaft, and a second step sprocket are attached. And one end of the step sprocket shaft is mounted on a support structure on one side of the passenger conveyor by a bearing, and the other end of the step sprocket shaft is connected to the stator of the drive motor by the bearing. The installed passenger conveyor drive is described (FIG. 4). In this drive device, the stator is fixed on the support structure on the other side of the passenger conveyor, and both end portions of the step sprocket shaft are fixed to the bearings installed on the support structure or fixed to the support structure. It is supported by a bearing installed on the child.
　また特許文献１には、回転子が取り付けられた回転子円盤と、固定子が取り付けられた固定子円盤と、回転子円盤の外周を半径方向に延長した環状ブレーキディスクとを備えた駆動モータが記載されている（第９図）。 Patent Document 1 discloses a drive motor that includes a rotor disk to which a rotor is attached, a stator disk to which a stator is attached, and an annular brake disk that extends the outer periphery of the rotor disk in the radial direction. It is described (FIG. 9).
　特許文献１の駆動装置では、ブレーキディスクを取り付けた電動機とスプロケットを単一の軸で直結している。 In the driving device of Patent Document 1, an electric motor equipped with a brake disk and a sprocket are directly connected by a single shaft.
特表２０００－５０５４０６号公報Special Table 2000-505406
　ところで、乗客コベンアは長期的な使用における保全作業の中で、劣化、故障、リニューアル等の理由によって部品交換を実施する場合がある。例えば、回転部に使用される軸受は、経年的な摩耗やはく離によって、異常音が発生する場合や、回転不良となる場合があるため、交換が必要となる。 By the way, the passenger covenor may perform parts replacement for reasons such as deterioration, failure, and renewal during maintenance work for long-term use. For example, a bearing used for a rotating part may need to be replaced because abnormal noise may occur due to wear or separation over time or rotation may be defective.
　交換作業を行う場合、乗客コンベア内の限られた空間内で部品交換を実施する、もしくは乗客コンベアの限られた開口部から交換対象の装置を取り出して乗客コンベア外で部品交換を実施する。しかし、大型の装置は着脱が容易ではなく、装置の着脱に相当の作業時間を要するといった課題があった。特に特許文献１で示されるような、電動機とステップスプロケット（以下、駆動スプロケットという）とを単一のスッテプスプロケット軸（以下、軸という）で直結する構造においては、軸受が電動機の内部に備えられており、軸受を交換する場合には軸に直結され一体となった電動機と駆動スプロケットとを取外す必要がある。しかし、軸は乗客コンベアのフレーム幅にほぼ等しい長さで、フレームの幅方向に配設されているため、軸や、この軸と一体に構成された電動機及び駆動スプロケットを取り外すことは容易ではない。このため、電動機と駆動スプロケットとを単一の軸で直結する構造では、軸受の交換作業は容易ではない。 When performing replacement work, parts are exchanged in a limited space inside the passenger conveyor, or parts to be exchanged are taken out from the limited opening of the passenger conveyor and parts are exchanged outside the passenger conveyor. However, there is a problem that a large apparatus is not easy to attach and detach, and requires considerable work time to attach and detach the apparatus. In particular, in a structure in which an electric motor and a step sprocket (hereinafter referred to as a drive sprocket) are directly connected by a single step sprocket shaft (hereinafter referred to as an axis) as shown in Patent Document 1, a bearing is provided inside the electric motor. In order to replace the bearing, it is necessary to remove the electric motor directly connected to the shaft and the driving sprocket. However, since the shaft has a length substantially equal to the frame width of the passenger conveyor and is disposed in the width direction of the frame, it is not easy to remove the shaft, the electric motor and the drive sprocket that are integrated with the shaft. . For this reason, in a structure in which the electric motor and the drive sprocket are directly connected by a single shaft, the replacement operation of the bearing is not easy.
　本発明の目的は、部品交換の作業性を向上させることができる乗客コンベアを提供することにある。 An object of the present invention is to provide a passenger conveyor that can improve the workability of parts replacement.
　上記目的を達成するために、本発明の乗客コンベアは、一方の乗降口と他方の乗降口との間を移動する無端状に連結された複数の踏板と、前記踏板の幅方向両側に設けられた欄干と、前記欄干上を前記踏板と同期して移動する移動手摺と、前記踏板を駆動及び制動する一対の駆動スプロケットとを備えた乗客コンベアにおいて、第一軸受で回転可能に軸支された電動機回転部を有する電動機ユニットと、第二軸受で回転可能に軸支されたブレーキディスクを有するブレーキディスクユニットと、駆動スプロケット軸と前記駆動スプロケット軸の両端部に配設した前記一対の駆動スプロケットとをユニット化した駆動スプロケットユニットとを備え、前記電動機ユニット、前記ブレーキディスクユニット及び前記駆動スプロケットユニットを同心状に配置し、前記電動機ユニットと前記ブレーキディスクユニットとを前記駆動スプロケットユニットにより着脱可能に連結する。 In order to achieve the above object, the passenger conveyor of the present invention is provided with a plurality of endlessly connected treads that move between one of the entrances and the other entrance, and both sides of the treadle in the width direction. In a passenger conveyor comprising a balustrade, a moving handrail that moves on the balustrade in synchronization with the tread, and a pair of drive sprockets that drive and brake the tread, the first bearing is rotatably supported An electric motor unit having an electric motor rotating part; a brake disk unit having a brake disk rotatably supported by a second bearing; a drive sprocket shaft; and the pair of drive sprockets disposed at both ends of the drive sprocket shaft; A drive sprocket unit, and the electric motor unit, the brake disk unit, and the drive sprocket unit. Arranged in heart shape, detachably connecting the brake disc unit and the electric motor unit by the drive sprocket unit.
　本発明によれば、スプロケットユニットを単独で取外すことにより、電動機ユニット及びブレーキユニットへのアクセスが容易となり、軸受等の部品交換の作業性を向上させることが出来る。 According to the present invention, by removing the sprocket unit alone, it becomes easy to access the electric motor unit and the brake unit, and the workability of exchanging parts such as bearings can be improved.
　上記した以外の課題、構成及び効果は、以下の実施形態の説明により明らかにされる。 Issues, configurations, and effects other than those described above will be clarified by the following description of the embodiments.

FIG. 4 is a side view of the drive sprocket unit 10 according to the embodiment of the present invention. FIG. 3 corresponds to a top view of the upper horizontal frame 2a.
　上部水平枠２ａ内の機械室３４には、駆動スプロケット３を含むスプロケットユニット１０、電動機ユニット１１及びブレーキディスクユニット１２を備えた駆動装置３５が据え付けられている。 In a machine room 34 in the upper horizontal frame 2a, a drive device 35 including a sprocket unit 10 including a drive sprocket 3, an electric motor unit 11, and a brake disk unit 12 is installed.
　スプロケットユニット１０はスプロケット軸１３、駆動スプロケット３ａ及び駆動スプロケット３ｂを備え、これらの部品がユニット化されている。一対の駆動スプロケット３ａ，３ｂは、スプロケット軸１３の両端部に設けられている。左右の駆動スプロケット３ａ及び駆動スプロケット３ｂはそれぞれの中心が一つの軸線上に位置するようにスプロケット軸１３により同心状に連結されている。このときスプロケット軸１３は、軸中心が駆動スプロケット３ａの中心及び駆動スプロケット３ｂの中心と共に、一つの軸線上に配置されるように連結されている。 The sprocket unit 10 includes a sprocket shaft 13, a drive sprocket 3a, and a drive sprocket 3b, and these parts are unitized. The pair of drive sprockets 3 a and 3 b are provided at both ends of the sprocket shaft 13. The left and right drive sprockets 3a and 3b are concentrically connected by a sprocket shaft 13 so that their centers are located on one axis. At this time, the sprocket shaft 13 is connected so that the shaft center is arranged on one axis together with the center of the drive sprocket 3a and the center of the drive sprocket 3b.
　このような構成により、本実施例のスプロケットユニット１０は、電動機ユニット１１の電動機軸受１６とブレーキディスクユニット１２のブレーキ軸受１９とにより、回転可能に軸支される。すなわち、スプロケットユニット１０のスプロケット軸１３は、電動機ユニット１１及びブレーキディスクユニット１２を介して、電動機軸受１６及びブレーキ軸受１９により回転可能に軸支される。 With such a configuration, the sprocket unit 10 of this embodiment is rotatably supported by the motor bearing 16 of the motor unit 11 and the brake bearing 19 of the brake disk unit 12. That is, the sprocket shaft 13 of the sprocket unit 10 is rotatably supported by the electric motor bearing 16 and the brake bearing 19 via the electric motor unit 11 and the brake disk unit 12.
　電動機ユニット１１は上部水平枠２ａに対して固定された電動機固定部１４と、電動機軸受１６と、電動機軸受１６で回転可能に軸支された電動機回転部１５とを備えている。ブレーキディスクユニット１２は、ブレーキ軸１８と、ブレーキ軸受１９と、ブレーキ軸受１９で回転可能に軸支されたブレーキディスク１７とを備えている。駆動装置３５には、ブレーキディスク１７と接触することによって駆動スプロケット３を制動するブレーキ２０が備えられている。 The electric motor unit 11 includes an electric motor fixing portion 14 fixed to the upper horizontal frame 2 a, an electric motor bearing 16, and an electric motor rotating portion 15 that is rotatably supported by the electric motor bearing 16. The brake disk unit 12 includes a brake shaft 18, a brake bearing 19, and a brake disk 17 that is rotatably supported by the brake bearing 19. The drive device 35 is provided with a brake 20 that brakes the drive sprocket 3 by contacting the brake disc 17.
　駆動スプロケット３ａ，３ｂには複数の貫通孔２１が設けられている。電動機回転部１５には、駆動スプロケット３の貫通孔２１と対応する位置に、めねじ２２が設けられている。またブレーキディスク１７には、駆動スプロケット３の貫通孔２１と対応する位置にめねじ２３が設けられている。 A plurality of through holes 21 are provided in the drive sprockets 3a and 3b. The electric motor rotating portion 15 is provided with a female screw 22 at a position corresponding to the through hole 21 of the drive sprocket 3. The brake disk 17 is provided with a female screw 23 at a position corresponding to the through hole 21 of the drive sprocket 3.
　駆動スプロケット３ａの貫通孔２１にボルト２４を挿通させ、ボルト２４をめねじ２２に螺合することで、駆動スプロケット３ａと電動機回転部１５とを連結する。また、駆動スプロケット３ｂの貫通孔２１にボルト２４を挿通させ、ボルト２４をめねじ２３に螺合することで、駆動スプロケット３ｂとブレーキディスク１７とを連結する。このとき、駆動スプロケット３ａと電動機回転部１５とは、それぞれの中心が一つの軸線上に位置するように同心状に締結される。駆動スプロケット３ｂとブレーキディスク１７とはそれぞれの中心が一つの軸線上に位置するように同心状に締結される。これにより、スプロケットユニット１０、電動機ユニット１１及びブレーキディスクユニット１２を同心状にかつ着脱可能に連結することができる。 The bolt 24 is inserted into the through hole 21 of the drive sprocket 3a, and the bolt 24 is screwed into the female screw 22, thereby connecting the drive sprocket 3a and the motor rotating unit 15. Further, the drive sprocket 3b and the brake disk 17 are connected by inserting a bolt 24 through the through hole 21 of the drive sprocket 3b and screwing the bolt 24 into the female screw 23. At this time, the drive sprocket 3a and the motor rotating unit 15 are fastened concentrically so that their centers are located on one axis. The drive sprocket 3b and the brake disc 17 are fastened concentrically so that their centers are located on one axis. Thereby, the sprocket unit 10, the electric motor unit 11, and the brake disc unit 12 can be connected concentrically and detachably.
　スプロケットユニット１０、電動機ユニット１１及びブレーキディスクユニット１２を分割する場合には、ボルト２４を取外すことで駆動スプロケット３ａと電動機回転部１５との締結、及び駆動スプロケット３ｂとブレーキディスク１７との締結を解けばよい。電動機ユニット１１及びブレーキディスクユニット１２から分離されたスプロケットユニット１０は、駆動スプロケット３ａと駆動スプロケット３ｂとが駆動装置３５に組み付けられた状態と同じ間隔（幅寸法）Ｌ２を有している。この幅寸法Ｌ２は各ユニット１０，１１，１２の中で最も大きな部品寸法になる。スプロケットユニット１０の幅寸法Ｌ２は踏板６の幅寸法以下の大きさであり、踏板６を取り外した後の開口部から容易に出し入れできる。 When the sprocket unit 10, the electric motor unit 11, and the brake disk unit 12 are divided, the bolt 24 is removed to release the connection between the drive sprocket 3 a and the electric motor rotating unit 15 and the connection between the drive sprocket 3 b and the brake disk 17. That's fine. The sprocket unit 10 separated from the electric motor unit 11 and the brake disk unit 12 has the same distance (width dimension) L2 as the state in which the drive sprocket 3a and the drive sprocket 3b are assembled to the drive device 35. The width dimension L2 is the largest part dimension among the units 10, 11, and 12. The width dimension L2 of the sprocket unit 10 is equal to or smaller than the width dimension of the tread board 6, and can be easily inserted and removed from the opening after the tread board 6 is removed.
　スプロケットユニット１０、電動機ユニット１１及びブレーキディスクユニット１２を分割することで、スプロケットユニット１０のみをエスカレータ１から取り外すことができ、電動機ユニット１１及びブレーキディスクユニット１２に容易にアクセスすることができる。これにより、軸受等の部品交換等の保全作業性を向上することができる。 By dividing the sprocket unit 10, the electric motor unit 11, and the brake disk unit 12, only the sprocket unit 10 can be removed from the escalator 1, and the electric motor unit 11 and the brake disk unit 12 can be easily accessed. Thereby, maintenance workability | operativity, such as replacement | exchange of components, such as a bearing, can be improved.
　なお、スプロケットユニット１０を取り外すときに、ブレーキディスク１７の重量によりブレーキ軸受１９の許容調心角を超えてブレーキ軸１８が傾く可能性がある。そこで、スプロケットユニット１０を取り外す場合には、ブレーキ２０を動作させてブレーキユニット１２を保持するか、ワイヤ等でブレーキユニット１２を固定することが望ましい。 When the sprocket unit 10 is removed, the brake shaft 18 may tilt beyond the allowable alignment angle of the brake bearing 19 due to the weight of the brake disc 17. Therefore, when removing the sprocket unit 10, it is desirable to operate the brake 20 to hold the brake unit 12 or to fix the brake unit 12 with a wire or the like.

Thereby, the adjustment operation | work adjusted to concentricity at the time of fastening of each unit 10,11,12 by the volt | bolt 24 can be made unnecessary.
　本実施例では、スプロケットユニット１０、電動機ユニット１１及びブレーキディスクユニット１２を容易に同心状に固定できる構造を有していることにより、スプロケットユニット１０、電動機ユニット１１及びブレーキディスクユニット１２の組み付け作業が容易になる。これにより、本実施例は軸受等の部品交換等の保全作業性を向上することができる。 In this embodiment, since the sprocket unit 10, the motor unit 11, and the brake disk unit 12 can be easily fixed concentrically, the assembly work of the sprocket unit 10, the motor unit 11, and the brake disk unit 12 can be performed.

　次に、図８を用いて、ブレーキディスク１７の構造を変更した例を説明する。図８は、本発明の実施例に係るブレーキディスクユニット１２の変更例を示す上面図である。なお、上述した実施例と同じ構成には同じ符号をつけ、説明を省略する。 Next, an example in which the structure of the brake disc 17 is changed will be described with reference to FIG. FIG. 8 is a top view showing a modified example of the brake disk unit 12 according to the embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the same structure as the Example mentioned above, and description is abbreviate | omitted.
　ブレーキディスクユニット１２は、ブレーキディスク１７と駆動スプロケット３ｂとの間にブレーキディスク連結ボス３２を備える。すなわち、上述した実施例では、図６に示すように、ブレーキディスク１７と一体化されていた連結ボス部１７ｂが、ブレーキディスク１７とは別部材として設けられている。 The brake disc unit 12 includes a brake disc connecting boss 32 between the brake disc 17 and the drive sprocket 3b. That is, in the above-described embodiment, as shown in FIG. 6, the connecting boss portion 17 b integrated with the brake disc 17 is provided as a separate member from the brake disc 17.
　また、ブレーキディスク１７は中心軸１７ａとは別部材として構成される。中心軸１７ａは連結ボス３２に固定されている。中心軸１７ａは連結ボス３２と一体に形成してもよいし、連結ボス３２とは別部材として形成した中心軸１７ａを連結ボス３２に固定してもよい。ブレーキディスクユニット１２が駆動装置３５に据え付けられた状態では、ブレーキディスク１７は中心軸１７ａと一体で回転する。 Further, the brake disc 17 is configured as a separate member from the central shaft 17a. The central shaft 17 a is fixed to the connecting boss 32. The central shaft 17 a may be formed integrally with the connecting boss 32, or the central shaft 17 a formed as a separate member from the connecting boss 32 may be fixed to the connecting boss 32. In a state where the brake disc unit 12 is installed on the drive device 35, the brake disc 17 rotates integrally with the central shaft 17a.
　以上説明したように、本変更例のブレーキディスクユニット１２は、ブレーキ軸受１９で回転可能に軸支された中心軸１７ａと、中心軸１７ａに固定され駆動スプロケット３ｂに連結される連結ボス３２とを有する。ブレーキディスク１７は連結ボス３２に着脱可能にかつ同心状に固定される。 As described above, the brake disk unit 12 of the present modification includes the central shaft 17a that is rotatably supported by the brake bearing 19 and the connecting boss 32 that is fixed to the central shaft 17a and connected to the drive sprocket 3b. Have. The brake disc 17 is detachably and concentrically fixed to the connecting boss 32.
　本変更例では、ブレーキディスク１７とブレーキディスク連結ボス３２とを締結するボルト３３を取り外すことで、ブレーキディスク１７のみをブレーキユニット１２から取り外すことができる。ブレーキディスク１７の取り外しを可能にするために、ブレーキディスク１７の中心部にはブレーキ軸受１９の外径Ｄ１９よりも大きい直径Ｄ１７を有する貫通孔１７ｃが形成されている。これにより、中心軸１７ａにブレーキ軸受１９を取り付けたまま、ブレーキディスク１７を中心軸１７ａ及び連結ボス３２から分離することができる。本変更例では、ブレーキディスク１７が損傷した場合等において、ブレーキディスク１７のみを交換でき、交換作業性を向上させることができる。 In this modified example, only the brake disk 17 can be removed from the brake unit 12 by removing the bolt 33 that fastens the brake disk 17 and the brake disk connecting boss 32. In order to allow the brake disc 17 to be removed, a through hole 17c having a diameter D17 larger than the outer diameter D19 of the brake bearing 19 is formed in the central portion of the brake disc 17.

In this modified example, when the brake disk 17 is damaged, only the brake disk 17 can be replaced, and the replacement workability can be improved.
　本発明に係る実施例及び変更例では、図２におけるスカート間の幅Ｌ１より、スプロケットユニット１０の全幅Ｌ２（図３参照）を小さくすることで、踏板６を取り外すことにより、左右のスカートガード７の間を通してスプロケットユニット１０を取り外すことが可能となる。 In the embodiment and the modification according to the present invention, the left and right skirt guards 7 are removed by removing the tread 6 by making the total width L2 (see FIG. 3) of the sprocket unit 10 smaller than the width L1 between the skirts in FIG. The sprocket unit 10 can be removed through the gap.
　一般的に乗客コンベアの枠（フレーム）２は踏板６を中心に左右同等の幅を有する。電動機１４，１５とブレーキディスク１７とを一体とする構造の場合、電動機１４，１５側のフレーム幅が増加する。その結果として、電動機１４，１５が配置される側とは反対側のフレーム幅も増加してしまう。本実施例では、電動機１４，１５とブレーキディスク１７とは左右の駆動スプロケット３ａ及び駆動スプロケット３ｂに分散して配置しているので、片側のフレーム幅の増加分を小さくすることができる。これにより、全体でのフレーム幅の増加を小さくすることができる。そして、本実施例では機械室を小型化することができる。 Generally, the frame 2 of the passenger conveyor has the same width on the left and right with the tread 6 as the center. In the case of a structure in which the electric motors 14 and 15 and the brake disc 17 are integrated, the frame width on the electric motors 14 and 15 side increases. As a result, the frame width on the side opposite to the side where the motors 14 and 15 are arranged is also increased. In this embodiment, the electric motors 14 and 15 and the brake disc 17 are arranged in the left and right drive sprockets 3a and 3b, so that the increase in the frame width on one side can be reduced. Thereby, the increase in the overall frame width can be reduced. In this embodiment, the machine room can be downsized.
