【発明の属する技術分野】
本発明は隣接踏板間に段差が生じるエスカレーターや隣接踏板間に段差が生じない電動道路等の乗客コンベアに係り、特に枠体の高さ寸法を小さくするのに好適な乗客コンベアに関する。
【０００２】
【従来の技術】
一般に乗客コンベアの高さの寸法、特に、枠体の高さ寸法を縮小する構成として、例えば特許文献１に開示の乗客コンベアが提案されている。
【０００３】
即ち、上記特許文献１に開示の乗客コンベアは、駆動装置を構成する減速装置と駆動用電動機を横方向に並べ、駆動装置全体としての高さ寸法の縮小を図っているものである。
【０００４】
【特許文献１】
特開昭５８−１０９３７５号公報（第５図，第６図）
【０００５】
【発明が解決しようとする課題】
上記従来の技術によれば、駆動装置としての高さ寸法の縮小化はできる。しかし、駆動装置の高さ寸法を縮小しても、例えば踏板方向転換部における駆動スプロケット及び従動スプロケットが従来と同じ大きさでは乗客コンベアの高さ寸法特に、枠体の高さ寸法の縮小化は望めない。
【０００６】
本発明の目的は、枠体の高さ寸法を縮小し得る乗客コンベアを提供することにある。
【０００７】
【課題を解決するための手段】
本発明は上記目的を達成するために、踏板の奥行き寸法を、踏板に軸支した走行輪の直径の３倍以下に形成すると共に、駆動装置を構成する歯車減速装置と駆動用電動機との動力の授受を可撓体を介して行ない、かつ前記駆動装置によって駆動される動力スプロケットと歯車減速装置と駆動用電動機とを平面的に見て乗客コンベアの枠体の長手方向に沿って配列したのである。
【０００８】
上記構成のうち歯車減速装置と駆動用電動機とを平面的に見て枠体の長手方向に沿って配列することで、歯車減速装置と駆動用電動機とを上下方向に重ねて配置することがなくなり、これによって駆動装置としての高さ寸法を低くすることができる。
【０００９】
さらに、上記構成のうち歯車減速装置と駆動用電動機とを可撓体を介して動力の授受を行なうことで、歯車減速装置の入力軸中心と駆動用電動機の出力軸中心とがずれても、歯車減速装置と駆動用電動機の一方側の高さ範囲内に他方側を配置することができる。これにより、駆動装置としての高さ寸法は、歯車減速装置と駆動用電動機のうち高さ寸法が高い方によって決めることができ、両者の高さ寸法が加算されることによる枠体の高さ寸法の増加をなくすことができるのである。
【００１０】
加えて、上記構成のうち踏板の奥行き寸法を、踏板に軸支した走行輪の直径の３倍以下に形成することで、駆動スプロケットや従動スプロケットを小径にしても方向転換時に隣接踏板が干渉することはなくなり、結果的に踏板方向転換部の高さ寸法を縮小することができる。
【００１１】
したがって、枠体の高さ寸法を決定する駆動装置と踏板方向転換部の高さ寸法を夫々縮小できるので、枠体の高さ寸法を縮小することができるのである。
【００１２】
【発明の実施の形態】
以下本発明による第１の実施の形態を、図１〜図３に示す電動道路に基づいて説明する。
【００１３】
床面１に設置される電動道路２は、床面１に形成されたピット１Ｐ内に収納される枠体３をベースに構成されている。この枠体３は長手方向の両端部に前記床面１と面一になる乗降床４Ａ，４Ｂを夫々備えており、これら乗降床４Ａ，４Ｂの下方に駆動スプロケット５と従動スプロケット６とを軸支している。
【００１４】
前記駆動スプロケット５は、駆動軸７上に間隔を空けて固定された一対の駆動スプロケット５Ａ，５Ｂを有しており、同様に前記従動スプロケット６も回転軸６Ｓ上一対固定されている。
【００１５】
前記駆動軸７及び回転軸６Ｓは、夫々両端を前記枠体３に軸受８Ａ，８Ｂを介して回転自在に支持されている。
【００１６】
前記一対の駆動スプロケット５Ａ，５Ｂと前記一対の従動スプロケット６間には無端状の踏板チェーン９が一対巻掛けられており、複数の踏板１０が一対の踏板チェーン９に連結されている。
【００１７】
これら踏板１０は、図２に示すように、奥行き方向の一側部の定位置に走行輪１１を軸支しており、奥行き方向の他側端に隣接する踏板の走行輪の輪軸を保持する軸受１２を隣接踏板側に向かって凸設している。この軸受１２は、踏板奥行き方向と平行で隣接踏板側に開口する凹溝を有しており、この凹溝に隣接踏板の走行輪の輪軸を係合させ、かつ摺動させている。前記走行輪１１は、前記枠体３内に敷設されたガイドレール（図示せず）に案内されて前記２つの乗降床４Ａ，４Ｂ間を循環移動するように構成されている。また、前記踏板１０の奥行き寸法Ｌは、走行輪１１の直径Ｄｒの３倍以下となる長さに形成されている。さらに、前記踏板１０の奥行き寸法Ｌは、走行輪１１の直径Ｄｒの３倍以下としたことにより、前記駆動スプロケット７及び従動スプロケット６の直径Ｄｓを、前記踏板１０の奥行き寸法Ｌの２倍以下で、高さ寸法Ｈの２倍以上に形成することができる。
【００１８】
前記踏板１０の両側に対向する前記枠体３には、踏板１０の移動方向に沿って欄干１３が立設されており、この欄干１３の周縁には移動手摺１４が移動できるように案内されている。
【００１９】
この移動手摺１４は、前記欄干１１の下方において手摺駆動装置１５によって前記踏板１０と同期速度で同方向に移動するように駆動される。手摺駆動装置１５は、駆動ローラ１６と従動ローラ１７によって前記移動手摺１４の表裏を挟圧している。そして駆動ローラ１６と同軸にスプロケット１８が固定されており、このスプロケット１８を回転させることにより、駆動ローラ１６を縦動ローラ１７側に押付けるようにして回転させ、前記移動手摺１４を駆動している。
【００２０】
前記駆動ローラ１６のスプロケット１８を駆動するために、前記駆動軸７から動力を得るように構成している。即ち、前記駆動軸７の駆動スプロケット５Ａ，５Ｂ間に設けた手摺駆動用の動力スプロケット１７と、前記駆動軸７よりも手摺駆動装置１５側寄りに軸支した中間軸２０に設けた中間スプロケット２１と、これら動力スプロケット１９と中間スプロケット２１とに巻掛けた連結チェーン２２と、前記中間軸２０の両端部に設けた一対の手摺駆動スプロケット２３Ａ，２３Ｂと、複数のガイドスプロケット２４を経由して手摺駆動スプロケット２３Ａ，２３Ｂと前記駆動ローラ１６のスプロケット１８間に巻掛けた駆動チェーン２５とによって前記駆動軸７の動力を手摺駆動装置１５に伝達している。
【００２１】
一方、駆動軸７に動力を付与する手段は、前記駆動スプロケット５Ｂよりも軸端側に固定された動力スプロケット２６と、駆動装置２７と、これら動力スプロケット２６と駆動装置２７間の動力を伝達する動力伝達チェーン２８とを備えている。
【００２２】
前記駆動装置２７は、例えば誘導電動機等の駆動電動機２９と歯車減速装置３０とを備えており、これらは共通のベース３１を介して前記枠体３に固定されている。これら駆動電動機２９と歯車減速装置３０は、平面的に見て枠体３の長手方向に沿って配置されており、また前記駆動電動機２９は、回転軸にフライホィール３２と小プーリ３３とを備え、前記歯車減速装置３０は入力プーリ３４と出力スプロケット３５とを備えている。
【００２３】
そして、駆動電動機２９の小プーリ３３と歯車減速装置３０の入力プーリ３４間に例えば３〜４連のＶベルトＶベルト３６を巻掛け、前記動力スプロケット２６に巻掛けた動力伝達チェーン２８を歯車減速装置３０の出力スプロケット３５に巻掛けることにより、駆動電動機２９の動力を駆動軸７に伝え、踏板１０と移動手摺１４を駆動している。
【００２４】
尚、駆動電動機２９の動力を歯車減速装置３０に伝えるのに、小プーリ３３と入力プーリ３４とＶベルト３６を用いたが、これらに限定されるものではなく、例えば動力伝達可撓体であるチェーンや歯付ベルトを用いると共に、これらに巻掛けるスプロケットやプーリを用いるようにしても良い。
【００２５】
また、駆動装置２７が設置された枠体３内の空所には、電動道路２の運転を制御する制御装置３７が内蔵されている。
【００２６】
このように本実施の形態によれば、駆動装置２７の駆動電動機２９と歯車減速装置３０とを平面的に見て重ならないように枠体３の長手方向に沿って配列したので、駆動装置２７の高さ寸法を低くでき、枠体３の高さ寸法を低くすることができる。
【００２７】
また、従来において、駆動電動機２９と歯車減速装置３０とを平面的に見て重ならないようにした上で、駆動電動機２９の回転軸と歯車減速装置３０の入力軸とを連結あるいは一体化するものが存在する。しかし、前記駆動電動機２９や前記歯車減速装置３０は容量や形状によって、その回転軸や入力軸の高さ方向の位置が大きく異なるので、これの軸を連結あるいは一体化した場合、駆動装置２７の高さ寸法を増大させることになる。即ち、図１において、駆動電動機２９の回転軸（小プーリ３３部）よりも高さが低い歯車減速装置３０の入力軸（入力プーリ３４部）を連結あるいは一体化した場合、駆動電動機２９の付属物であるフライホィール３２は２点鎖線に示すフライホィール３２Ｓのように位置することになり、枠体３の下方に突出することになる。この突出をなくすには、駆動電動機２９と歯車減速装置３０とを別個のベースに支持させた上で枠体３内に固定しなければならず、駆動装置２７の枠体３内への設置を複雑化し、多大な労力を必要とする。
【００２８】
したがって、本実施の形態のように、駆動電動機２９と歯車減速装置３０とを平面的に見て重ならないようにした上で、可撓体により動力の授受を行なうことが重要である。
【００２９】
さらに、駆動電動機２９の小プーリ３３と歯車減速装置３０の入力プーリ３４及び出力スプロケット３５とを、動力スプロケット２６側に向け、これらに可撓体である動力伝達チェーン２８及びＶベルト３６を巻掛けるようにしたので、駆動電動機２９と歯車減速装置３０の回動部分は全て枠体３の幅方向端部側に位置し、その結果、保守運転時に作業者が回動部分に接することはなく、保守時の安全性を高めることができる。
【００３０】
このほか、本実施の形態のように構成することにより、駆動電動機２９と歯車減速装置３０間で減速機構を構成することもでき、その結果、歯車減速装置３０と合わせてきめ細かな減速比を得ることができると共に、歯車減速装置３０を小型化することも可能である。
【００３１】
ところで上記実施の形態において、乗客コンベアとして電動道路を説明したが、エスカレーターにも適用できることは云うまでもない。
【００３２】
即ち、エスカレーターにおいても、踏段方向転換部における駆動スプロケット及び従動スプロケットが従来と同じでは駆動装置の高さ寸法を縮小しても、枠体の高さ寸法の縮小化は望めない。
【００３３】
そこで、エスカレーターにおいては、上記実施の形態と同じように、歯車減速装置と駆動用電動機とを配置すると共に、踏段の上段側に軸支された走行輪の踏段方向転換時における移動軌跡を駆動スプロケットと従動スプロケットの外周側に位置させることにより、これら駆動スプロケットと従動スプロケットの直径を踏段の奥行き寸法の２倍以下で踏段の高さ寸法の２倍以上とすることで、踏段の方向転換部の枠体の高さ寸法を縮小することができる。
【００３４】
【発明の効果】
以上説明したように本発明によれば、枠体の高さ寸法を縮小し得る乗客コンベアを得ることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a passenger conveyor such as an escalator in which a step is formed between adjacent treads or an electric road in which a step is not formed between adjacent treads, and more particularly to a passenger conveyor suitable for reducing a height of a frame body.
[0002]
[Prior art]
In general, as a configuration for reducing the height dimension of a passenger conveyor, particularly, the height dimension of a frame, a passenger conveyor disclosed in Patent Document 1, for example, has been proposed.
[0003]
That is, in the passenger conveyor disclosed in Patent Document 1, a reduction gear and a drive motor constituting a drive device are arranged side by side to reduce the height of the entire drive device.
[0004]
[Patent Document 1]
JP-A-58-109375 (FIGS. 5 and 6)
[0005]
[Problems to be solved by the invention]
According to the above conventional technique, the height of the driving device can be reduced. However, even if the height of the driving device is reduced, for example, if the driving sprocket and the driven sprocket in the tread direction changing part are the same size as the conventional one, the reduction of the height of the passenger conveyor, particularly, the reduction of the height of the frame body is not possible. I can't hope.
[0006]
An object of the present invention is to provide a passenger conveyor capable of reducing the height of a frame.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention has a stepping plate having a depth dimension not more than three times the diameter of a traveling wheel pivotally supported by the stepping plate, and a power drive of a gear reduction device and a driving motor constituting a driving device. The power sprocket, the gear reduction device, and the drive motor driven by the drive device are arranged along the longitudinal direction of the frame of the passenger conveyor when viewed in plan. is there.
[0008]
By arranging the gear reduction device and the driving motor in the longitudinal direction of the frame when viewed in plan view, the gear reduction device and the driving motor do not overlap with each other in the vertical direction. Thus, the height of the driving device can be reduced.
[0009]
Furthermore, by transmitting and receiving power between the gear reduction device and the driving motor through the flexible body in the above configuration, even if the center of the input shaft of the gear reduction device and the center of the output shaft of the driving motor are shifted, The other side can be arranged within the height range of one side of the gear reduction device and the drive motor. Thereby, the height dimension as the driving device can be determined by the higher one of the gear reduction device and the driving motor, and the height dimension of the frame body is obtained by adding the height dimensions of both. Can be eliminated.
[0010]
In addition, in the above configuration, the depth of the tread is formed to be three times or less the diameter of the traveling wheel pivotally supported by the tread, so that even if the driving sprocket and the driven sprocket have a small diameter, the adjacent tread interferes when turning. As a result, the height of the tread direction changing portion can be reduced.
[0011]
Therefore, since the height of the driving device for determining the height of the frame and the height of the tread direction changing portion can be reduced, the height of the frame can be reduced.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a first embodiment of the present invention will be described based on an electric road shown in FIGS.
[0013]
The electric road 2 installed on the floor 1 is configured based on a frame 3 housed in a pit 1P formed on the floor 1. The frame 3 is provided at both ends in the longitudinal direction with floors 4A and 4B, respectively, which are flush with the floor surface 1. A drive sprocket 5 and a driven sprocket 6 are provided below the floors 4A and 4B. It supports.
[0014]
The drive sprocket 5 has a pair of drive sprockets 5A and 5B fixed on the drive shaft 7 at intervals, and similarly, the driven sprocket 6 is also fixed on the rotary shaft 6S.
[0015]
Both ends of the drive shaft 7 and the rotary shaft 6S are rotatably supported by the frame 3 via bearings 8A and 8B.
[0016]
A pair of endless tread chains 9 is wound between the pair of drive sprockets 5A and 5B and the pair of driven sprockets 6, and a plurality of tread plates 10 are connected to the pair of tread chain 9.
[0017]
As shown in FIG. 2, these treads 10 support the running wheels 11 at fixed positions on one side in the depth direction, and hold the wheelset of the running wheels of the treads adjacent to the other end in the depth direction. The bearing 12 protrudes toward the adjacent tread side. The bearing 12 has a concave groove parallel to the depth direction of the tread plate and opened to the side of the adjacent tread plate, and the wheel shaft of the running wheel of the adjacent tread plate is engaged with the concave groove and slid. The running wheels 11 are configured to be guided by guide rails (not shown) laid in the frame 3 and circulate between the two floors 4A and 4B. Further, the depth dimension L of the tread plate 10 is formed to a length that is three times or less the diameter Dr of the traveling wheel 11. Further, the depth L of the tread plate 10 is set to be three times or less the diameter Dr of the traveling wheel 11, so that the diameter Ds of the driving sprocket 7 and the driven sprocket 6 is set to two times or less of the depth L of the tread plate 10. Thus, it can be formed to be at least twice the height dimension H.
[0018]
A balustrade 13 is erected along the moving direction of the tread plate 10 on the frame 3 facing both sides of the tread plate 10, and a moving handrail 14 is guided on the periphery of the balustrade 13 so as to be movable. I have.
[0019]
The moving handrail 14 is driven by the handrail driving device 15 below the balustrade 11 so as to move in the same direction at the same speed as the tread plate 10. The handrail driving device 15 presses the front and back of the moving handrail 14 with a driving roller 16 and a driven roller 17. A sprocket 18 is fixed coaxially with the driving roller 16. By rotating the sprocket 18, the driving roller 16 is rotated so as to be pressed against the longitudinal roller 17, and the moving handrail 14 is driven. I have.
[0020]
In order to drive the sprocket 18 of the drive roller 16, power is obtained from the drive shaft 7. That is, a power sprocket 17 for driving handrails provided between the drive sprockets 5A and 5B of the drive shaft 7, and an intermediate sprocket 21 provided on an intermediate shaft 20 that is supported closer to the handrail drive device 15 than the drive shaft 7 is. A connecting chain 22 wound around the power sprocket 19 and the intermediate sprocket 21, a pair of handrail driving sprockets 23A and 23B provided at both ends of the intermediate shaft 20, and a handrail via a plurality of guide sprockets 24. The power of the drive shaft 7 is transmitted to the handrail drive device 15 by the drive sprockets 23A, 23B and the drive chain 25 wound around the sprocket 18 of the drive roller 16.
[0021]
On the other hand, means for applying power to the drive shaft 7 transmits a power sprocket 26 fixed to the shaft end side of the drive sprocket 5B, a drive device 27, and power between the power sprocket 26 and the drive device 27. And a power transmission chain 28.
[0022]
The drive device 27 includes a drive motor 29 such as an induction motor and a gear reduction device 30, which are fixed to the frame 3 via a common base 31. The drive motor 29 and the gear reduction device 30 are arranged along the longitudinal direction of the frame 3 in plan view, and the drive motor 29 includes a flywheel 32 and a small pulley 33 on a rotating shaft. The gear reduction device 30 includes an input pulley 34 and an output sprocket 35.
[0023]
Then, for example, three to four V-belts V-belts 36 are wound between the small pulley 33 of the driving motor 29 and the input pulley 34 of the gear reduction device 30, and the power transmission chain 28 wound around the power sprocket 26 is gear-reduced. By being wound around the output sprocket 35 of the device 30, the power of the drive motor 29 is transmitted to the drive shaft 7 to drive the tread plate 10 and the moving handrail 14.
[0024]
Note that the small pulley 33, the input pulley 34, and the V-belt 36 are used to transmit the power of the drive motor 29 to the gear reduction device 30, but the present invention is not limited thereto. For example, a power transmission flexible body is used. A chain or a toothed belt may be used, and a sprocket or a pulley wound around these may be used.
[0025]
A control device 37 for controlling the operation of the electric road 2 is built in an empty space in the frame 3 in which the driving device 27 is installed.
[0026]
As described above, according to the present embodiment, the drive motor 29 of the drive device 27 and the gear reduction device 30 are arranged along the longitudinal direction of the frame body 3 so as not to overlap in plan view. Can be reduced, and the height of the frame 3 can be reduced.
[0027]
Conventionally, the drive motor 29 and the gear reduction device 30 are not overlapped in a plan view, and then the rotation shaft of the drive motor 29 and the input shaft of the gear reduction device 30 are connected or integrated. Exists. However, the position of the drive motor 29 and the gear reduction device 30 in the height direction of the rotation shaft and the input shaft thereof greatly differ depending on the capacity and shape. This would increase the height dimension. That is, in FIG. 1, when the input shaft (input pulley 34) of the gear reduction device 30 whose height is lower than the rotation shaft of the drive motor 29 (small pulley 33) is connected or integrated, the drive motor 29 is attached. The flywheel 32 as an object is located like a flywheel 32S shown by a two-dot chain line, and projects below the frame 3. In order to eliminate this protrusion, the drive motor 29 and the gear reduction device 30 must be supported on separate bases and fixed in the frame 3, and the drive device 27 must be installed in the frame 3. It is complicated and requires a lot of effort.
[0028]
Therefore, as in the present embodiment, it is important that the drive motor 29 and the gear reduction device 30 are not overlapped in a plan view, and that power is transferred by a flexible body.
[0029]
Further, the small pulley 33 of the drive motor 29 and the input pulley 34 and the output sprocket 35 of the gear reduction device 30 are directed toward the power sprocket 26, and the power transmission chain 28 and the V belt 36, which are flexible bodies, are wound around these. As a result, the rotating portions of the drive motor 29 and the gear reduction device 30 are all located on the widthwise end side of the frame 3, so that the worker does not touch the rotating portion during maintenance operation. Safety during maintenance can be improved.
[0030]
In addition, with the configuration as in the present embodiment, a reduction mechanism can be configured between the drive motor 29 and the gear reduction device 30, and as a result, a fine reduction ratio can be obtained in combination with the gear reduction device 30. In addition to this, the gear reduction device 30 can be downsized.
[0031]
By the way, in the above embodiment, the electric road has been described as the passenger conveyor, but it is needless to say that the present invention can be applied to an escalator.
[0032]
That is, even in the escalator, if the driving sprocket and the driven sprocket in the step direction changing portion are the same as those in the related art, it is not possible to reduce the height of the frame even if the height of the driving device is reduced.
[0033]
Therefore, in the escalator, similarly to the above embodiment, the gear reduction device and the driving motor are arranged, and the traveling trajectory of the traveling wheel pivotally supported on the upper side of the step when the step direction changes is used as the drive sprocket. And the outer peripheral side of the driven sprocket, the diameter of the driving sprocket and the driven sprocket is not more than twice the depth of the step and not less than twice the height of the step, so that the direction change portion of the step can be used. The height of the frame can be reduced.
[0034]
【The invention's effect】
As described above, according to the present invention, it is possible to obtain a passenger conveyor capable of reducing the height of the frame.
