Description

本発明は、エスカレータや動く歩道など（以下、エスカレータ等と称す）の保全装置に関するものである。   The present invention relates to a maintenance device for escalators, moving walkways, and the like (hereinafter referred to as escalators).

従来のエスカレータ等の手摺駆動装置は、図３に示すように、手摺１の裏面と表面を駆動ローラ２と押圧ローラ３とで挟圧することによって手摺１を駆動するように構成されている。
特開２００１−２２００８２号公報 As shown in FIG. 3, a conventional handrail driving device such as an escalator is configured to drive the handrail 1 by sandwiching the back surface and the front surface of the handrail 1 with a driving roller 2 and a pressing roller 3.
Japanese Patent Laid-Open No. 2001-220082

このような駆動装置では、エスカレータ等が長時間停止状態にあれば、駆動ローラ２及び押圧ローラ３による挟圧のため塑性変形、つまり圧痕が手摺１に生じることになる。このため、エスカレータ等の停止時には押圧ローラ３による挟圧を解除させるものが提案されているが、機構上の工夫が欠かせない問題があった。   In such a driving device, if the escalator or the like is in a stopped state for a long time, plastic deformation, that is, indentation is generated in the handrail 1 due to pinching by the driving roller 2 and the pressing roller 3. For this reason, there has been proposed one that releases the pinching pressure by the pressing roller 3 when the escalator or the like is stopped, but there has been a problem that a device on the mechanism is indispensable.

本発明は、乗客の乗るステップの両側に、電動機により駆動される手摺を備えたエスカレータ等において、該手摺の停止時間を検出する検出手段と、通常の電力を供給する電源スイッチと、該電源スイッチがＯＦＦでも前記電動機に電力を供給する保全スイッチとを設け、前記電源スイッチがＯＮ、かつ、前記検出手段が前記手摺の停止を所定時間以上検出した時、前記手摺を僅かでも移動するように前記電動機に駆動指令し、前記電源スイッチがＯＦＦ、かつ、前記保全スイッチがＯＮの時、所定間隔で前記電動機に駆動指令する手段を備えるものである。 The present invention relates to a detection means for detecting a stop time of the handrail , a power switch for supplying normal power, and the power switch in an escalator having a handrail driven by an electric motor on both sides of a passenger boarding step. A maintenance switch for supplying electric power to the electric motor even when the power is off, and when the power switch is on and the detection means detects the stop of the handrail for a predetermined time or more, the handrail is moved so as to move even slightly. A drive command is given to the motor, and when the power switch is OFF and the maintenance switch is ON, there is provided means for commanding the motor to drive at a predetermined interval.

基本的に電気的な処理のみで済むため、物理的・機構的なスペースは必要がなく、極めて簡単にエスカレータ等の保全が可能である。   Since only electrical processing is basically required, there is no need for physical and mechanical space, and escalators and the like can be maintained very easily.

電源スイッチの入・切に関わらず、所定時間以上手摺の停止状態が続かないようにするものである。たとえ僅かでも手摺を移動させるようにするものである。   Regardless of whether the power switch is on or off, the handrail is kept from being stopped for a predetermined time. Even if it is a little, the handrail is moved.

以下、本発明の実施例について、図面を用いて説明する。図１は本発明の保全装置の全体図、図２は本発明装置の動作を示すフローチャート図である。 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall view of the maintenance apparatus of the present invention, and FIG. 2 is a flowchart showing the operation of the apparatus of the present invention.

図中、図３と同一符号のものは同一のものを示すが、１０は電動機、１１はスプロケットで、チェーン１０ａを介して電動機１０により回転する。１２はたとえば減速機や変速機、１３は本発明に係る手摺駆動装置、１４は本発明にかかる検出装置で、手摺１が所定時間停止状態にあるか否かを検出するものである。１５は本発明に係る保全スイッチで、夜間や休日などに通常の電源スイッチが切られていると時に、この保全スイッチを操作すれば電動機１０には電力が供給されるが、表示案内装置などには供給されないものである。尚、２０は乗客が乗るステップである。  In the figure, the same reference numerals as those in FIG. 3 denote the same components, but 10 is an electric motor, 11 is a sprocket, and is rotated by the electric motor 10 through a chain 10a. For example, 12 is a reduction gear or transmission, 13 is a handrail drive device according to the present invention, 14 is a detection device according to the present invention, and detects whether or not the handrail 1 is stopped for a predetermined time. 15 is a maintenance switch according to the present invention. When a normal power switch is turned off at night or on holidays, when this maintenance switch is operated, electric power is supplied to the motor 10, but the display guide device or the like is used. Is not supplied. In addition, 20 is a step in which a passenger gets.

本発明では、図２に示すように、先ず電源が入っている状態か否かをチェックし、電源が入っている通常の場合には、検出装置１４により所定時間以上（たとえば長時間）手摺１が停止状態かどうかをチェックして、停止状態であれば、このまま放置すると手摺１に圧痕を生じるため、電動機１０に駆動指令を送り、短時間駆動を行うようにする。この際には微速で動かすのが安全上望ましい。次に、夜間などのように電源を完全に落としてしまう場合には、本発明に係る保全スイッチ１５を入れるようにすると、最低限電動機１０には電力が供給されて長時間停止状態にならない程度に、手摺１を所定の間隔を置いて間欠的に短時間駆動させるものである。この場合も、微速で動かす方が望ましいと考えられる。   In the present invention, as shown in FIG. 2, first, it is checked whether or not the power is turned on. In the normal case where the power is turned on, the handrail 1 is used for a predetermined time or longer (for example, a long time) by the detection device 14. If it is in the stopped state, if it is left as it is, an indentation will be generated in the handrail 1, so that a drive command is sent to the electric motor 10 to drive for a short time. In this case, it is desirable for safety to move at a slow speed. Next, when the power is completely turned off at night or the like, if the maintenance switch 15 according to the present invention is turned on, the electric power is supplied to the electric motor 10 at a minimum so that it does not stop for a long time. In addition, the handrail 1 is intermittently driven for a short time at a predetermined interval. Also in this case, it is considered preferable to move at a slow speed.

夜間や休日などのように、予めエスカレータ等が長時間停止状態になると予測される場合には、休日スイッチ投入やタイマースイッチなどにより、電動機１０に対して超微速駆動指令を与えるようにしても良い。   When it is predicted that the escalator or the like will be stopped for a long time in advance such as at night or on holidays, an ultra-low speed drive command may be given to the motor 10 by turning on a holiday switch or a timer switch. good.

最近は、インバータを利用したエスカレータ等の駆動装置が増えてきているので、インバータを使用すればこの微速を簡単に実現できる。本発明によれば、機構上特別な装置や対応が不要となる。   Recently, the number of driving devices such as escalators using inverters has increased, and this low speed can be easily realized by using inverters. According to the present invention, there is no need for a special device or response in terms of mechanism.

以上の説明では、通常の運転の場合と、夜間・休日などの長時間停止の場合とに、検出分けを行って対応する例を挙げているが、スイッチ投入やタイマーなどによって自動的・間欠的に手摺を動かす、或いは超微速で連続駆動させるようにすることも可能である。   In the above description, an example is given to detect and respond to normal operation and long-term stoppages such as nighttime and holidays. It is also possible to move the handrail or to drive continuously at an extremely low speed.
