Description

この発明は、エスカレータや動く歩道などの乗客コンベアに備えられている手すりベルトを自動的に清掃する手すりベルト清掃装置に関する。   The present invention relates to a handrail belt cleaning device for automatically cleaning a handrail belt provided on a passenger conveyor such as an escalator or a moving sidewalk.

エスカレータや動く歩道などの乗客コンベアにおいては、乗客が乗るステップと同期して無限循環移動する手すりベルトが設けられ、ステップに乗った乗客がその手すりベルトに手を添えて身体を支えるようになっている。
手すりベルトは、ゴムなどの弾性材で無端状に形成され、ステップの両側の欄干の縁部に走行可能に装着され、それぞれ駆動装置により欄干に沿って無限循環移動するように駆動される。手すりベルトの駆動装置は、駆動ローラを備え、この駆動ローラが手すりベルトの裏面に圧接され、その摩擦力で手すりベルトに駆動ローラの回転動力が伝えられ、手すりベルトがその長手方向に走行する。
ところで、手すりベルトは時間の経過とともに徐々に汚れてくる。このため、特開２００７−３１４２９８公報に見られるように、手すりベルトの表面に清掃具を接触させ、その清掃具で自動的に手すりベルトの表面を清掃するような手段が採られる。
特開２００７−３１４２９８公報 Passenger conveyors such as escalators and moving walkways are provided with handrail belts that move infinitely in synchronization with the steps on which passengers ride, and passengers riding on steps attach their hands to the handrail belts to support their bodies. Yes.
The handrail belt is formed endlessly with an elastic material such as rubber, and is attached to the edge of the balustrade on both sides of the step so as to be able to run, and is driven so as to move infinitely along the balustrade by a driving device. The driving device for the handrail belt includes a driving roller. The driving roller is pressed against the back surface of the handrail belt, the rotational force of the driving roller is transmitted to the handrail belt by the friction force, and the handrail belt travels in the longitudinal direction.
By the way, the handrail belt gradually gets dirty with time. For this reason, as seen in Japanese Patent Application Laid-Open No. 2007-314298, a means is adopted in which a cleaning tool is brought into contact with the surface of the handrail belt and the surface of the handrail belt is automatically cleaned with the cleaning tool.
JP2007-314298A

手すりベルトの表面を清掃する目的は、手すりベルトの表面はステップに乗る乗客が直接手で触れる部分であるから、乗客が不快感をもたないようにその表面を汚れのない綺麗な状態に保つためである。   The purpose of cleaning the surface of the handrail belt is to keep the surface of the handrail belt clean and clean so that passengers do not feel uncomfortable because the surface of the handrail belt is the part that the passengers on the step touch directly with their hands Because.

しかしながら、手すりベルトはその裏面も徐々に汚れてくる。手すりベルトの多くは、裏面に補強用のキャンバス材（ズック材）が裏打ちされており、このため滑らかな表面よりも汚れやすい。   However, the handrail belt gradually gets dirty on the back. Many handrail belts are lined with a reinforcing canvas material (zock material) on the back, which makes them more prone to dirt than a smooth surface.

手すりベルトを駆動する駆動ローラは手すりベルトの裏面に圧接され、その圧接による摩擦力で手すりベルトを駆動しており、したがって手すりベルトの裏面が汚れてくるとその摩擦力が低減し、所定の速度で手すりベルトを走行させる駆動能力が低下してしまう。
このため、従来では、エスカレータの定期点検時などに、エスカレータの運転を止め、手すりベルトを欄干から外し、裏面側を表に向けて手作業で手すりベルトの裏面の汚れを落とすようにしている。
しかしながら、このような手段では、作業に多大な労力と時間を要し、能率性が悪く、コストもかかってしまう。
この発明はこのような点に着目してなされたもので、その目的とするところは、手すりベルトの裏面を自動的に能率よく清掃して、人手に依ることなく手すりベルトの駆動能力を常に適正に保つことができる乗客コンベアの手すりベルト清掃装置を提供することにある。 The driving roller that drives the handrail belt is pressed against the back surface of the handrail belt, and the handrail belt is driven by the frictional force generated by the pressure contact. Therefore, when the back surface of the handrail belt becomes dirty, the friction force is reduced and the predetermined speed is reached. As a result, the driving ability for running the handrail belt is reduced.
For this reason, conventionally, at the time of periodic inspection of the escalator, the operation of the escalator is stopped, the handrail belt is removed from the balustrade, and the back surface of the handrail belt is manually cleaned with the back side facing up.
However, such a method requires a lot of labor and time for work, is inefficient and costly.
The present invention has been made paying attention to such points, and the object of the present invention is to automatically and efficiently clean the back surface of the handrail belt so that the driving ability of the handrail belt is always appropriate without depending on human hands. It is in providing the handrail belt cleaning apparatus of the passenger conveyor which can be maintained in this.

デッキ１２の例えば下階側端部の内側には、手すりベルト１４を清掃するための清掃装置２０が設けられている。図２には清掃装置２０の全体の斜視図を、図３には清掃装置２０の主要部の断面図を、図４には清掃装置２０の正面図をそれぞれ示してある。 The driving roller 15 is pressed against the C-shaped inner surface of the handrail belt 14, and a chain 16 is wound between the driving roller 15 and the driving wheel 3, and the driving roller 15 is linked with the driving wheel 3. The handrail belt 14 rotates indefinitely in synchronization with each step 9 by the rotation of the driving roller 15.
A cleaning device 20 for cleaning the handrail belt 14 is provided on the inside of the lower floor side end portion of the deck 12, for example. 2 is a perspective view of the entire cleaning device 20, FIG. 3 is a sectional view of the main part of the cleaning device 20, and FIG. 4 is a front view of the cleaning device 20.

清掃装置２０は、図３に示すように枢軸２２を備え、この枢軸２２がトラス１の一部のフレーム材１ａに取り付け固定されている。枢軸２２は、手すりベルト１４の下側を通り、かつ手すりベルト１４の長手方向と直交する方向に延びている。
枢軸２２の基部には、図２及び図４に示すように短冊状のベース２６がフレーム材１ａと対向して取り付けられ、このベース２６の枢軸２２の反対側の端部に、その枢軸２２と並列して支持軸２７が取り付けられている。枢軸２２は手すりベルト１４の表面側に配置され、支持軸２７は手すりベルト１４の裏面側に配置され、枢軸２２と支持軸２７とが手すりベルト１４を隔てて互いに反対側に位置するように配置されている。
枢軸２２には、基部に駆動プーリ２９が、先端部に摩擦ローラ３０がそれぞれ回転自在に装着され、これら駆動プーリ２９と摩擦ローラ３０は、枢軸２２に回転自在に嵌合されたスリーブ３１を介して一体的に連結され、枢軸２２を中心にして一体的に回転する。
支持軸２７には、基部に従動プーリ３３が、先端部に清掃ローラ３４がそれぞれ回転自在に装着され、これら従動プーリ３３と清掃ローラ３４は、支持軸２７に回転自在に嵌合されたスリーブ３５を介して一体的に連結され、支持軸２７を中心にして一体的に回転する。
駆動プーリ２９と従動プーリ３３との間には、無端状の駆動ベルト３７が掛け渡され、この駆動ベルト３７を介して駆動プーリ２９の回転動力が従動プーリ３３に伝達され、従動プーリ３３と一体的に清掃ローラ３４が回転する。駆動ベルト３７としては、例えば駆動プーリ２９及び従動プーリ３３と接触する内周面に凹凸状の歯を有する歯付きベルトとなっている。 As shown in FIG. 3, the cleaning device 20 includes a pivot 22, and the pivot 22 is attached and fixed to a part of the frame material 1 a of the truss 1. The pivot 22 passes under the handrail belt 14 and extends in a direction perpendicular to the longitudinal direction of the handrail belt 14.
As shown in FIGS. 2 and 4, a strip-shaped base 26 is attached to the base of the pivot 22 so as to face the frame material 1 a, and the pivot 22 is connected to the end of the base 26 opposite to the pivot 22. A support shaft 27 is attached in parallel. The pivot shaft 22 is disposed on the front surface side of the handrail belt 14, the support shaft 27 is disposed on the back surface side of the handrail belt 14, and the pivot shaft 22 and the support shaft 27 are disposed opposite to each other across the handrail belt 14. Has been.
A drive pulley 29 is rotatably mounted on the base portion of the pivot shaft 22 and a friction roller 30 is rotatably mounted on the tip portion thereof. The drive pulley 29 and the friction roller 30 are connected to each other via a sleeve 31 that is rotatably fitted to the pivot shaft 22. Are integrally connected, and rotate integrally around the pivot 22.
The support shaft 27 has a driven pulley 33 at the base and a cleaning roller 34 rotatably mounted at the tip thereof. The driven pulley 33 and the cleaning roller 34 are rotatably fitted to the support shaft 27. And are integrally connected to each other about the support shaft 27.
An endless drive belt 37 is stretched between the drive pulley 29 and the driven pulley 33, and the rotational power of the drive pulley 29 is transmitted to the driven pulley 33 via the drive belt 37, and is integrated with the driven pulley 33. Accordingly, the cleaning roller 34 rotates. The drive belt 37 is, for example, a toothed belt having concave and convex teeth on the inner peripheral surface that contacts the drive pulley 29 and the driven pulley 33.

摩擦ローラ３０は摩擦係数の大きな材料、例えばゴムからなり、手すりベルト１４の表面に所定の圧力で接触するように圧接されている。清掃ローラ３４は周面に例えばナイロン製の多数のブラシ毛３４ａを有するブラシ型ローラで、手すりベルト１４の裏面に所定の圧力で接触するように圧接されている。そして、摩擦ローラ３０と清掃ローラ３４は手すりベルト１４を挟んで斜めに対向するように配置されている。   The friction roller 30 is made of a material having a large friction coefficient, for example, rubber, and is pressed against the surface of the handrail belt 14 at a predetermined pressure. The cleaning roller 34 is a brush type roller having a large number of brush bristles 34a made of nylon, for example, on its peripheral surface, and is pressed against the back surface of the handrail belt 14 with a predetermined pressure. The friction roller 30 and the cleaning roller 34 are disposed so as to face each other with the handrail belt 14 interposed therebetween.

支持軸２７が取り付けられたベース２６は、枢軸２２を中心にして回動することが可能で、このベース２６の回動で清掃ローラ３４の位置を変えてその周面と手すりベルト１４の裏面との接触圧を調整することが可能となっている。すなわち、ベース２６には、枢軸２２を中心とする円弧状の長孔３９が形成され、この長孔３９を通してフレーム材１ａにボルト４０が螺挿され、このボルト４０の締付けによりベース２６がフレーム材１ａに固定されている。そしてボルト４０を緩め、ベース２６を枢軸２２を中心に回動することで、清掃ローラ３４の周面と手すりベルト１４の裏面との接触圧を調整することができるようになっている。
ベース２６には、図２に示すように、清掃ローラ３４の両側に位置して一対のごみ受皿４３，４４が設けられている。これらごみ受皿４３，４４は手すりベルト１４の内側に挿入され、清掃ローラ３４と手すりベルト１４との接触部に近接するようにフレーム材１ａに支持されている。
次に、作用について説明する。 The base 26 to which the support shaft 27 is attached can be rotated around the pivot shaft 22, and the position of the cleaning roller 34 is changed by the rotation of the base 26 and its peripheral surface and the back surface of the handrail belt 14. It is possible to adjust the contact pressure. That is, the base 26 is formed with an arc-shaped long hole 39 centered on the pivot 22, and a bolt 40 is screwed into the frame material 1 a through the long hole 39, and the base 26 is fixed to the frame material by tightening the bolt 40. It is fixed to 1a. Then, by loosening the bolt 40 and rotating the base 26 around the pivot shaft 22, the contact pressure between the peripheral surface of the cleaning roller 34 and the back surface of the handrail belt 14 can be adjusted.
As shown in FIG. 2, the base 26 is provided with a pair of dust trays 43 and 44 located on both sides of the cleaning roller 34. These dust trays 43 and 44 are inserted inside the handrail belt 14 and supported by the frame material 1 a so as to be close to the contact portion between the cleaning roller 34 and the handrail belt 14.
Next, the operation will be described.

エスカレータの上昇運転時には、各ステップ９及び手すりベルト１４が図２及び図４に示す矢印Ａ方向に移動する。そして、手すりベルト１４のＡ方向に移動で、摩擦ローラ３０が手すりベルト１４との摩擦力でＡ方向に回転し、この摩擦ローラ３０と一体的に駆動プーリ２９がＡ方向に回転し、さらにこの駆動プーリ２９の回転で従動プーリ３３及び清掃ローラ３４が一体的にＡ方向に回転する。   During the ascending operation of the escalator, each step 9 and the handrail belt 14 move in the direction of arrow A shown in FIGS. When the handrail belt 14 moves in the A direction, the friction roller 30 rotates in the A direction by the frictional force with the handrail belt 14, and the drive pulley 29 rotates in the A direction integrally with the friction roller 30. The driven pulley 33 and the cleaning roller 34 are integrally rotated in the A direction by the rotation of the driving pulley 29.

清掃ローラ３４の回転により、そのブラシ毛３４ａで手すりベルト１４の裏面が擦られ、その裏面の汚れが落とされる。このとき、手すりベルト１４はＡ方向に移動し、清掃ローラ３４はＡ方向に回転するが、そのＡ方向の移動とＡ方向の回転は互いに向き合う逆方向の関係にあり、このため清掃ローラ３４のブラシ毛３４ａにより手すりベルト１４の裏面が有効に擦られ、効率よくその裏面の汚れが落とされ、綺麗に清掃される。この際の汚れ屑はごみ受皿４４内に収容される。   Due to the rotation of the cleaning roller 34, the back surface of the handrail belt 14 is rubbed by the brush bristles 34a, and the dirt on the back surface is removed. At this time, the handrail belt 14 moves in the A direction, and the cleaning roller 34 rotates in the A direction. However, the movement in the A direction and the rotation in the A direction are in a reverse relationship facing each other. The back surface of the handrail belt 14 is effectively rubbed by the brush bristles 34a, and the back surface is efficiently cleaned and cleaned cleanly. At this time, the dirt is accommodated in the garbage tray 44.

他方、エスカレータの下降運転時には、各ステップ９及び手すりベルト１４が矢印Ｂ方向に移動する。そして、手すりベルト１４のＢ方向の移動で、摩擦ローラ３０が手すりベルト１４との摩擦力でＢ方向に回転し、この摩擦ローラ３０と一体的に駆動プーリ２９がＢ方向に回転し、さらにこの駆動プーリ２９の回転で従動プーリ３３及び清掃ローラ３４が一体的にＢ方向に回転し、清掃ローラ３４の回転で手すりベルト１４の裏面が清掃される。   On the other hand, during the descending operation of the escalator, each step 9 and the handrail belt 14 move in the arrow B direction. Then, as the handrail belt 14 moves in the B direction, the friction roller 30 rotates in the B direction by the frictional force with the handrail belt 14, and the drive pulley 29 rotates in the B direction integrally with the friction roller 30. The driven pulley 33 and the cleaning roller 34 are integrally rotated in the direction B by the rotation of the driving pulley 29, and the back surface of the handrail belt 14 is cleaned by the rotation of the cleaning roller 34.

このときにおいても、手すりベルト１４のＢ方向に移動と、清掃ローラ３４のＢ方向の回転は、互いに向う逆方向の関係にあり、このため清掃ローラ３４のブラシ毛３４ａにより手すりベルト１４の裏面が有効に擦られ、効率よくその裏面の汚れが落とされ、綺麗に清掃される。この際の汚れ屑はごみ受皿４３内に収容される。
手すりベルト１４の清掃でごみ受皿４３，４４に汚れ屑が溜まったときには、エスカレータの運転を停止し、ごみ受皿４３，４４内から汚れ屑を除去して廃棄する。 Even at this time, the movement of the handrail belt 14 in the B direction and the rotation of the cleaning roller 34 in the B direction are in opposite directions to each other, and therefore the back surface of the handrail belt 14 is moved by the brush bristles 34a of the cleaning roller 34. It is effectively rubbed and the backside is efficiently cleaned and cleaned cleanly. At this time, dirt waste is accommodated in the garbage tray 43.
When dirt scraps are collected in the dust trays 43, 44 by cleaning the handrail belt 14, the operation of the escalator is stopped, and the dirt scraps are removed from the dust trays 43, 44 and discarded.

このように、手すりベルト１４の裏面は、その手すりベルト１４の移動に応じて回転する清掃ローラ３４により自動的に効率よく清掃され、したがって手すりベルト１４を駆動するための駆動ローラ１５と手すりベルト１４との間の摩擦力を常に適正に保ち、駆動ローラ１５で手すりベルト１４を常に所定の速度で的確に走行させることができる。
清掃ローラ３４の周面のブラシ毛３４ａが摩耗するなどして清掃ローラ３４と手すりベルト１４の裏面との接触圧が低下したような場合には、ボルト４０を緩め、ベース２６を枢軸２２を中心に下方に回動し、清掃ローラ３４の周面を手すりベルト１４の裏面に押し付けてその接触圧を調整する。そして適正な接触圧に調整した後に、前記ボルト４０を締付け、ベース２６をフレーム材１ａに固定する。これにより清掃ローラ３４の周面と手すりベルト１４の裏面との接触圧を適正な圧力に保つことができる。
なお、この発明は、建屋の上下階に渡って斜めに設置されるエスカレータに適用する場合に限らず、各ステップが同一の平面上で移動してそのステップに乗った乗客を一方向に搬送する動く歩道などの乗客コンベアにおいても同様に適用することが可能であることは言うまでもない。 As described above, the back surface of the handrail belt 14 is automatically and efficiently cleaned by the cleaning roller 34 that rotates in accordance with the movement of the handrail belt 14, and thus the driving roller 15 and the handrail belt 14 for driving the handrail belt 14. Therefore, the handrail belt 14 can always travel accurately at a predetermined speed with the driving roller 15.
When the contact pressure between the cleaning roller 34 and the back surface of the handrail belt 14 decreases due to wear of the brush bristles 34a on the peripheral surface of the cleaning roller 34, the bolt 40 is loosened, and the base 26 is centered on the pivot shaft 22. Then, the peripheral surface of the cleaning roller 34 is pressed against the back surface of the handrail belt 14 to adjust the contact pressure. And after adjusting to an appropriate contact pressure, the said volt | bolt 40 is tightened and the base 26 is fixed to the frame material 1a. Thereby, the contact pressure between the peripheral surface of the cleaning roller 34 and the back surface of the handrail belt 14 can be maintained at an appropriate pressure.
In addition, this invention is not only applied to the escalator installed diagonally across the upper and lower floors of the building, but each step moves on the same plane and conveys passengers who ride on that step in one direction Needless to say, the present invention can also be applied to passenger conveyors such as moving walkways.
