Description

この発明はエスカレータや動く歩道などとして好ましく用いられる乗客コンベア装置に関するものである。   The present invention relates to a passenger conveyor device preferably used as an escalator or a moving sidewalk.

従来の乗客コンベア装置として、無端状に連結され往路と復路とを循環移動する複数の踏段と、前記踏段の前位側に設けられた前位側ローラ支持部と、前記前位側ローラ支持部に軸支された前位側ローラと、前記踏段の後位側に設けられた後位側ローラ支持部と、前記後位側ローラ支持部に軸支された後位側ローラと、前記踏段の前記往路と前記復路との間の折返し区間に設けられ、前記踏段の姿勢を反転させて前記踏段の移動方向を変化させる踏段折返し機構と、前記踏段の折返し区間において、前記後位側ローラ支持部及び前記後位側ローラを拘束しないで前記踏段の姿勢を制御する踏段姿勢制御機構とを備えたものがある（例えば特許文献１参照。）。   As a conventional passenger conveyor device, a plurality of steps connected endlessly and circulated and moved between an outward path and a return path, a front roller support section provided on the front side of the step, and the front roller support section A rear roller supported on the rear side of the step, a rear roller support provided on the rear side of the step, a rear roller supported on the rear roller support, and A step-turning mechanism that is provided in a turn-back section between the forward path and the return path, and reverses the posture of the step to change the moving direction of the step; and, in the turn-back section of the step, the rear roller support portion And a step posture control mechanism that controls the posture of the step without restraining the rear roller (see, for example, Patent Document 1).

特開２００１−３１３５５号公報（第１頁、図１）JP 2001-31355 A (first page, FIG. 1)

上記のような従来の乗客コンベア装置では、踏段反転部における踏段折返し機構に踏段スプロケットが用いられているため、通常では作用しない地震荷重やその他の外力が踏段の幅方向に作用しても、踏段が幅方向に自ずから拘束されているのでローラが他の部材と干渉することはない。しかし、踏段反転部に踏段スプロケットを用いないものでは、上記地震荷重等大きな力が作用したときにエスカレータの上部では乗客コンベアがＤＮ（下）方向、下部では乗客コンベアがＵＰ（上）方向となる場合に、乗客コンベアの往路側においてローラが踏段反転部の円弧状の反転レールから直線部に進入する際、即ち反転終了部近傍で、ローラが横方向に移動して干渉が発生し、踏段等に損傷を与える可能性があるという課題があった。   In the conventional passenger conveyor apparatus as described above, a step sprocket is used for the step turn-back mechanism in the step reversing part. Therefore, even if an earthquake load or other external force that does not normally operate acts in the width direction of the step, Are naturally restrained in the width direction, so that the roller does not interfere with other members. However, in the case where a step sprocket is not used in the step reversing part, when a large force such as the above-mentioned seismic load is applied, the passenger conveyor is in the DN (down) direction at the top of the escalator and the passenger conveyor is in the UP (up) direction at the bottom. In this case, when the roller enters the straight portion from the arc-shaped reversing rail of the step reversing portion on the forward path side of the passenger conveyor, that is, near the reversing end portion, the roller moves in the lateral direction, causing interference, and so on. There was a problem that there is a possibility of damaging.

この発明は、上記のような従来技術の課題を解消するためになされたもので、地震動等によって万一踏段の駆動ローラが乗客コンベアの幅方向に変位した場合であっても、安全に乗客コンベアをガイドでき、安全性の向上された乗客コンベア装置を得ることを目的としている。   The present invention has been made to solve the above-described problems of the prior art, and even if the driving roller of the step is displaced in the width direction of the passenger conveyor due to earthquake motion or the like, the passenger conveyor can be safely It is an object to obtain a passenger conveyor device with improved safety.

この発明に係る乗客コンベア装置は、駆動ローラを有する踏段が無端状に連結された踏段鎖と、この踏段鎖の移動方向を反転させる踏段反転部と、この踏段反転部における上記駆動ローラの移動経路に配設されて転動する駆動ローラを案内支持する円弧状の駆動ローラ反転レールと、この駆動ローラ反転レールの反転終了部近傍に上記駆動ローラの進入部を有して該駆動ローラの両側部を覆うように配設され、該進入部の開口幅が地震時における該駆動ローラの横方向変位量を超える寸法に広げられたローラガイドとを備えるようにしたものである。   A passenger conveyor device according to the present invention includes a step chain in which steps having a driving roller are connected endlessly, a step reversing unit that reverses the moving direction of the step chain, and a movement path of the driving roller in the step reversing unit An arc-shaped driving roller reversing rail that guides and supports the driving roller that is arranged and rolls, and has an entrance portion for the driving roller in the vicinity of the reversing end portion of the driving roller reversing rail, and both sides of the driving roller. And a roller guide that is widened so that the opening width of the entry portion exceeds the lateral displacement of the drive roller during an earthquake.

この発明においては、駆動ローラ反転レールの反転終了部近傍に、進入部の開口幅が地震時における該駆動ローラの横方向変位量を超える寸法に広げられたローラガイドを設けたことにより、駆動ローラが地震等により変位しても該ローラガイドにより駆動ローラが正規の位置にガイドされ、踏段等に損傷を与えることなく運転を継続できる。このため、乗客コンベアの安全性が向上する。   In this invention, the driving roller is provided in the vicinity of the reversal end portion of the driving roller reversing rail by having a roller guide whose opening width is larger than the lateral displacement of the driving roller at the time of an earthquake. Even if the roller is displaced due to an earthquake or the like, the roller guide guides the driving roller to a normal position, and the operation can be continued without damaging the steps. For this reason, the safety of the passenger conveyor is improved.

実施の形態１．
図１〜図５はこの発明の実施の形態１による乗客コンベア装置を説明するもので、図１は全体構成を示す側面図、図２は図１のＩＩ−ＩＩ線における矢視断面相当図、図３は図２のＩＩＩ−ＩＩＩ線における矢視断面相当図、図４は図３の踏段を除いたレール構成及びローラガイドを概念的に示す側面図である。図５は図４に示されたローラガイドの動作を説明する図で、（ａ）は駆動ローラがローラガイドに進入したときの側面図、（ｂ）は正常に進入したときの矢視Ｄ相当図、（ｃ）は異常時の矢視Ｄ相当図である。なお、各図を通じて同一符号は同一部分を示している。図において、乗客コンベア装置は、上階と下階の建築梁間に固定された乗客コンベア主枠１に設けられた、所定数の踏段２が無端状に連結された踏段鎖２０が下階の円Ａで囲む踏段反転部Ｒ及び上階の円Ｂで囲む踏段反転部の間に掛け渡され、傾斜部（中間部）に配された駆動装置３により循環移動するように構成されている。 Embodiment 1 FIG.
1 to 5 illustrate a passenger conveyor device according to Embodiment 1 of the present invention, FIG. 1 is a side view showing the overall configuration, and FIG. 2 is a cross-sectional view corresponding to an arrow line II-II in FIG. 3 is a cross-sectional view taken along the line III-III in FIG. 2, and FIG. 4 is a side view conceptually showing the rail configuration and the roller guide excluding the step in FIG. 5A and 5B are diagrams for explaining the operation of the roller guide shown in FIG. 4, wherein FIG. 5A is a side view when the driving roller enters the roller guide, and FIG. 5B corresponds to the arrow D when the drive roller enters normally. FIG. 4C is a view corresponding to an arrow D at the time of abnormality. Note that the same reference numerals denote the same parts throughout the drawings. In the figure, the passenger conveyor device is a circle on the lower floor, which is provided on a passenger conveyor main frame 1 fixed between building beams on the upper floor and the lower floor and in which a predetermined number of steps 2 are connected endlessly. It is spanned between the step reversing part R surrounded by A and the step reversing part surrounded by a circle B on the upper floor, and is configured to circulate and move by the driving device 3 arranged in the inclined part (intermediate part).

踏段２は踏段本体２１と踏段本体２１に固定された踏段軸２２と踏段軸２２の左右両端部に設けられた一対の駆動ローラ２３と踏段本体２１に設けられた一対の追従ローラ２４とを有し、隣接する踏段２は駆動ローラ２３を有する踏段軸２２の両端部に枢支された左右各１本のリンク２５によって相互に連結されている。踏段２は傾斜部を含む直線部Ｌにおいては、駆動ローラ２３が駆動ローラ２３用の第１レール４、及び追従ローラ２４が追従ローラ２４用の第２レール５によってそれぞれ案内されることにより循環経路に沿って移動される。踏段反転部Ｒにおいては、駆動ローラ２３用の円弧状の駆動ローラ反転レール４１（４１ａ、４１ｂ）、及び追従ローラ２４用の半円形状の追従ローラ反転レール５１が、図４に示すように設けられており、駆動ローラ２３及び追従ローラ２４が駆動ローラ反転レール４１及び追従ローラ反転レール５１をそれぞれ転動して案内され、踏段鎖２０が反転される。   The step 2 includes a step body 21, a step shaft 22 fixed to the step body 21, a pair of driving rollers 23 provided at both left and right ends of the step shaft 22, and a pair of follower rollers 24 provided on the step body 21. The adjacent steps 2 are connected to each other by one link 25 on each of the left and right sides pivoted at both ends of the step shaft 22 having the driving roller 23. In the step 2, in the straight line portion L including the inclined portion, the drive roller 23 is guided by the first rail 4 for the drive roller 23, and the follower roller 24 is guided by the second rail 5 for the follower roller 24. Is moved along. In the step reversing section R, an arcuate driving roller reversing rail 41 (41a, 41b) for the driving roller 23 and a semicircular following roller reversing rail 51 for the following roller 24 are provided as shown in FIG. The drive roller 23 and the follower roller 24 are guided by rolling on the drive roller reverse rail 41 and the follower roller reverse rail 51, respectively, and the step chain 20 is reversed.

なお、駆動ローラ反転レール４１は踏段鎖２０の構造上（リンク構造）、剛性が確保されることから、自立して姿勢を維持可能であり、反転機構上横方向のガイドが不要となる利点があることから、図示の構造となっている。第１レール４及び駆動ローラ反転レール４１ｂの境界部近傍には、図４、図５に示すように駆動ローラ反転レール４１ｂの反転終了部近傍と直線部Ｌとに跨って駆動ローラ２３の両側部を上から覆うように設けられ、図５（ａ）の円Ｅで囲む進入部６ａの開口幅Ｗ（図５（ｂ）に図示）が、地震時における駆動ローラ２３の横方向変位量を超える寸法、具体的には、地震時に想定される駆動ローラ２３に働く矢印Ｆ（図５（ｃ））方向の力による横方向変位量に移動ガタ相当分を加えた寸法に広げられ、直線部Ｌ側の他端部６ｂ方向に狭めるように形成されたローラガイド６が設けられている。なお、図２〜図５は図１の円Ａで囲む下階側の踏段反転部Ｒを示しているが、円Ｂで囲む上階側の踏段反転部も対称的に同様に構成されている。   The driving roller reversing rail 41 has the advantage that the structure of the step chain 20 (link structure) and the rigidity are secured, so that the driving roller reversing rail 41 can maintain its posture independently and does not require a lateral guide on the reversing mechanism. Since there is, it has the structure shown in the figure. In the vicinity of the boundary between the first rail 4 and the driving roller reversing rail 41b, both sides of the driving roller 23 straddle the reversal end portion and the straight line portion L of the driving roller reversing rail 41b as shown in FIGS. The opening width W (shown in FIG. 5B) of the entry portion 6a surrounded by the circle E in FIG. 5A exceeds the lateral displacement amount of the drive roller 23 at the time of the earthquake. The dimension is expanded to the dimension obtained by adding the amount equivalent to the movement back to the amount of lateral displacement due to the force in the direction of arrow F (FIG. 5 (c)) acting on the drive roller 23 assumed at the time of the earthquake. A roller guide 6 formed so as to be narrowed in the direction of the other end 6b on the side is provided. 2 to 5 show the lower floor side reversing portion R surrounded by the circle A in FIG. 1, but the upper floor side reversing portion surrounded by the circle B is similarly configured in a symmetrical manner. .

次に、上記のように構成された実施の形態１の動作について説明する。駆動装置３は、図示省略している駆動キャタピラと噛み合うリンク２５を踏段２の進行方向前側に押し出し、同時に進行方向後方のリンク２５を引っ張り込んで踏段鎖２０を連続移動させる。踏段反転部Ｒにおいては、踏段２は上記駆動装置３の駆動キャタピラによる押し出しと引っ張り込み、並びに駆動ローラ反転レール４１及び追従ローラ反転レール５１により駆動ローラ２３及び追従ローラ２４がガイドされて図３の矢印Ｃで示す方向に動作して反転する。更に具体的には踏段２の駆動ローラ２３は駆動ローラ反転レール４１ａ及び４１ｂにより案内され、踏段２の追従ローラ２４は第２レール５及び半円形状の追従ローラ反転レール５１により案内されることにより、循環経路に沿って反転する。駆動ローラ２３が図５（ａ）に示す反転終了部に移動したとき、通常時においては図５（ｂ）に示すように駆動ローラ２３はローラガイド６の幅方向略中央部に進入してガイドされる。   Next, the operation of the first embodiment configured as described above will be described. The driving device 3 pushes the link 25 meshing with a driving caterpillar (not shown) to the front side in the traveling direction of the step 2 and simultaneously pulls the link 25 behind the traveling direction to continuously move the step chain 20. In the step reversing portion R, the step 2 is pushed and pulled by the driving caterpillar of the driving device 3, and the driving roller 23 and the following roller 24 are guided by the driving roller reversing rail 41 and the following roller reversing rail 51, as shown in FIG. Operate in the direction indicated by arrow C and reverse. More specifically, the driving roller 23 of the step 2 is guided by the driving roller reversing rails 41a and 41b, and the follower roller 24 of the step 2 is guided by the second rail 5 and the semicircular following roller reversing rail 51. Invert along the circulation path. When the driving roller 23 moves to the reversal end portion shown in FIG. 5A, the driving roller 23 enters the guide substantially in the center in the width direction of the roller guide 6 as shown in FIG. Is done.

一方、通常時には作用しない地震荷重やその他の外力Ｆ（または−Ｆ）が万一駆動ローラ２３に作用した際に、踏段鎖２０のガタ等により駆動ローラ２３が図５（ｃ）に示すように横方向に移動する場合が想定されるが、その場合には、駆動ローラ２３の両側部を上から覆うように設けられたローラガイド６の進入部６ａの開口幅Ｗが地震時に想定される横方向変位量に移動ガタ相当分を加えた移動量を確保した値に広げられていることにより、駆動ローラ２３はローラガイド６により的確に正規の軌道に誘導され、踏段２の姿勢を正常に保てることから、踏段２の損傷等の発生を防止できる。なお、下階側の踏板反転部ＲにおけるＵＰ運転の場合について説明したが、上階側の踏段反転部についても同様であり、上階側の場合はＤＮ運転の際に同様に動作する。   On the other hand, when an earthquake load or other external force F (or -F) that does not normally operate acts on the drive roller 23, the drive roller 23 is caused by backlash or the like of the step chain 20 as shown in FIG. Although the case where it moves to a horizontal direction is assumed, in that case, the opening width W of the entrance part 6a of the roller guide 6 provided so that the both sides of the drive roller 23 may be covered from the top is assumed in the time of an earthquake. The driving roller 23 is accurately guided to the normal orbit by the roller guide 6 and can maintain the normal posture of the step 2 by being widened to a value that secures the amount of movement obtained by adding the amount equivalent to the amount of movement to the direction displacement amount. Therefore, it is possible to prevent the step 2 from being damaged. In addition, although the case of UP operation in the stepboard reversing portion R on the lower floor side has been described, the same applies to the step reversal portion on the upper floor side, and in the case of the upper floor side, the same operation is performed during DN operation.

上記のように、この実施の形態１によれば、駆動ローラ反転レール４１の反転終了部近傍と直線部とに跨って駆動ローラ２３の両側部を覆うように配設されたローラガイド６の進入部６ａの開口幅Ｗを、地震時における駆動ローラ２３の横方向変位量に移動ガタ相当分を加えた寸法に広げ、直線部Ｌ側の他端部６ｂ方向に狭めるようにしたことにより、万一乗客コンベアの踏段反転部Ｒにおいて地震等による外力により踏段鎖２０や駆動ローラ２３が幅方向に変位した場合でも的確に駆動ローラ２３を正規の軌道に誘導することが可能となり、安全に踏段２を走行させることができる効果が得られる。また、ローラガイド６は踏段鎖２０の往路側における踏段２が下から上に反転してくる反転終了部近傍の上方に進入部６ａが位置するように設けられているので、踏段鎖２０の横方向の変位に対して的確に対応できる。   As described above, according to the first embodiment, the roller guide 6 is disposed so as to cover both sides of the drive roller 23 across the vicinity of the reverse end portion of the drive roller reverse rail 41 and the straight line portion. By expanding the opening width W of the portion 6a to a dimension obtained by adding the amount equivalent to the movement back to the lateral displacement amount of the driving roller 23 at the time of an earthquake, and narrowing in the direction of the other end portion 6b on the linear portion L side, Even when the step chain 20 and the driving roller 23 are displaced in the width direction due to an external force due to an earthquake or the like in the step reversing portion R of the one-passenger conveyor, the driving roller 23 can be accurately guided to the normal track, and the step 2 can be safely performed. The effect that can be made to travel is obtained. Further, since the roller guide 6 is provided so that the entry portion 6a is positioned above the inversion end portion where the step 2 on the forward path side of the step chain 20 is inverted from the bottom to the top, the side of the step chain 20 It is possible to accurately cope with the displacement in the direction.

実施の形態２．
図６はこの発明の実施の形態２による乗客コンベア装置のローラガイドを説明するもので、（ａ）は側面図、（ｂ）は上面図である。図において、ローラガイド６は第１レール４の側方部に設けられた固定ブラケット７１に対してカム体７２を介して第１レール４に略平行な矢印Ｇ方向に移動可能に固定され、カム体７２の移動方向両側部に設けられた圧縮バネなどの２つのバネ体７３により矢印Ｇで示す可動方向の中央部に保持され、鉛直方向の移動は拘束されている。なお、固定ブラケット７１は乗客コンベア主枠１（図１）等に固定されており、該固定ブラケット７１、カム体７２、及びバネ体７３によりローラガイド６の支持部材７を構成している。上記カム体７２の凹部からなる係合部７２ａには固定ブラケット７１に固定された検知スイッチ８が係合しており、ローラガイド６が矢印Ｇ方向に所定距離移動したときに検知スイッチ８が動作して図示省略している乗客コンベア装置の制御部に信号を送り、例えば乗客コンベア装置を停止させるように構成されている。その他の構成は実施の形態１と同様であるので説明を省略する。 Embodiment 2. FIG.
6A and 6B illustrate a roller guide of a passenger conveyor device according to Embodiment 2 of the present invention. FIG. 6A is a side view, and FIG. 6B is a top view. In the figure, a roller guide 6 is fixed to a fixed bracket 71 provided on a side portion of the first rail 4 via a cam body 72 so as to be movable in the direction of an arrow G substantially parallel to the first rail 4. The body 72 is held at the center of the movable direction indicated by the arrow G by two spring bodies 73 such as compression springs provided on both sides in the movement direction, and the movement in the vertical direction is restricted. The fixed bracket 71 is fixed to the passenger conveyor main frame 1 (FIG. 1) and the like, and the support bracket 7 of the roller guide 6 is configured by the fixed bracket 71, the cam body 72, and the spring body 73. The detection switch 8 fixed to the fixing bracket 71 is engaged with the engaging portion 72a formed of the concave portion of the cam body 72, and the detection switch 8 operates when the roller guide 6 moves a predetermined distance in the arrow G direction. And a signal is sent to the control part of the passenger conveyor apparatus which is abbreviate | omitting illustration, for example, it is comprised so that a passenger conveyor apparatus may be stopped. Since other configurations are the same as those of the first embodiment, description thereof is omitted.

上記のように構成された実施の形態２においては、通常では作用しない地震荷重やその他の外力が万一作用し、駆動ローラ２３が横方向に移動して、ローラガイド６に強く干渉した際には、駆動ローラ２３を正規の位置にガイドしつつ、ローラガイド６が駆動ローラ２３の進行方向に矢印Ｈのように移動する。これによりカム体７２も同時に移動し、検知スイッチ８を動作させる。図示省略している乗客コンベア装置の制御部は検知スイッチ８からの信号により乗客コンベアを安全に停止させる。なお、検知スイッチ８が動作しない程度の変位の場合は、駆動ローラ２３がローラガイド６によって実施の形態１と同様に正規の位置にガイドされることで運転が支障なく継続される。   In the second embodiment configured as described above, when an earthquake load or other external force that does not normally operate acts, the driving roller 23 moves in the lateral direction and strongly interferes with the roller guide 6. The roller guide 6 moves in the direction of travel of the drive roller 23 as indicated by an arrow H while guiding the drive roller 23 to a normal position. As a result, the cam body 72 also moves simultaneously, and the detection switch 8 is operated. The control unit of the passenger conveyor device (not shown) safely stops the passenger conveyor by a signal from the detection switch 8. When the displacement is such that the detection switch 8 does not operate, the driving roller 23 is guided to the normal position by the roller guide 6 as in the first embodiment, and the operation is continued without any trouble.

上記のように、実施の形態２によれば実施の形態１と同様の効果が得られる他、ローラガイド６に駆動ローラ２３が強く干渉した際に、検知スイッチ８が動作して図示省略している乗客コンベア装置の制御部に信号を送り、乗客コンベアを安全に停止させることができるという効果が得られる。
なお、上記実施の形態１、２では乗客コンベア装置がエスカレータの場合について説明したが、動く歩道などでも同様に用いることができることは言うまでもない。 As described above, according to the second embodiment, the same effect as in the first embodiment can be obtained, and when the driving roller 23 strongly interferes with the roller guide 6, the detection switch 8 operates and the illustration is omitted. A signal is sent to the control part of the passenger conveyor apparatus which exists, and the effect that a passenger conveyor can be stopped safely is acquired.
In the first and second embodiments, the case where the passenger conveyor device is an escalator has been described, but it goes without saying that it can also be used on a moving sidewalk.
