この発明は１手摺の速度とステップの速度とを同期化さ
せるように制御するエスカレータの制御装置に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an escalator control device that controls the speed of one handrail and the speed of each step to be synchronized.
従来のエスカレータは第３図に示すとおりステップを駆
動する電動機から動力をとって手摺を摩擦駆動するよう
になっていた。As shown in FIG. 3, conventional escalators use electric motors that drive the steps to drive the handrails by friction.
すなわち、第３図において、（ｌ）は電動機、（２）は
この電動機（１）に駆動される減速機、（３）はこの減
速機（２）に駆動される上部鎖歯車で、下部鎖歯車（４
）との間に巻き掛けられた無端の鎖（図示しない。）を
駆動するものである。（５）は上記鋼に多段に係止され
たステップで、鎖を介して減速機（３）によって駆動さ
れる。（６）は鎖（６ａ）を介して減速機（３）に駆動
される手摺駆動装置で、ローラで手摺（７）を挾んで摩
擦駆動するものである。That is, in Fig. 3, (l) is an electric motor, (2) is a reduction gear driven by this electric motor (1), (3) is an upper chain gear driven by this reduction gear (2), and a lower chain gear is driven by this reduction gear (2). Gear (4
) that drives an endless chain (not shown) that is wound between the (5) is a step that is latched to the steel in multiple stages and is driven by a speed reducer (3) via a chain. (6) is a handrail drive device driven by a speed reducer (3) via a chain (6a), which grips the handrail (7) with rollers and drives it by friction.
通常の使用状態では１乗客は手摺（７）を把持する程度
であるから１乗客が多くなってもたいした負荷は手摺（
））にはかからないので、ステップ（５）と同期して移
動する。In normal use, each passenger only has to grip the handrail (7), so even if there are more passengers, the load is still on the handrail (7).
)), it moves in synchronization with step (5).
しかし、上昇運転でステップ（６）上の人が体重を手摺
（７）にかけ、この手摺（７）の動力で上昇するように
すると１手摺（７）に大きな力がかかる。このような乗
り方は異常であって、極めて稀にしか起きないとしても
子供等では十分考えられることである。However, when the person on the step (6) puts his/her weight on the handrail (7) during ascending operation and uses the power of this handrail (7) to ascend, a large force is applied to one handrail (7). This kind of riding style is abnormal, and even if it occurs only very rarely, it is entirely possible for children to ride the vehicle.
また１手摺（７）に手荷物を載せることはよくあること
であって、この場合でも手摺（７）に大きな力がかかる
＠更にまた。ある乗客がステップ（５）上で身体のバラ
ンスを失ない、この影響で別の乗客もバランスを失い、
将棋倒し的に伝って相当数の人がステップ上でバランス
を失ったとする。このような場合、これらの相浩数の乗
客がほり同時に手摺を把持して体勢を整えたうとする。Furthermore, it is common for baggage to be placed on the handrail (7), and even in this case, a large force is applied to the handrail (7). One passenger loses his or her balance on the step (5), and another passenger also loses his or her balance due to this effect.
Suppose that a considerable number of people lose their balance on the steps due to a shogi-like situation. In such a case, a large number of passengers simultaneously grab the handrail and try to prepare themselves.
このために手摺（７）に大きな力がかかる。For this reason, a large force is applied to the handrail (7).
このような場合、特に高揚程のエスカレータでは１乗客
数が多くなるので１手摺（７）にかかる力も大きくなる
。ところで１手摺（７）は上記のとおり摩擦駆動であっ
て１日本昇降機安全センター・日本エレベータ協会発行
「、ｒｘｓム４３０２昇降機の検査標準解説（昭和５１
年版）」第１０１頁第１３〜１６頁によると１手摺（７
）を約１５に９の力で引張っても停止しないことが記載
されている。In such a case, especially in a high-height escalator, the number of passengers increases, so the force applied to each handrail (7) also increases. By the way, 1 handrail (7) is friction driven as mentioned above, and 1 is published by the Japan Elevator Safety Center and the Japan Elevator Association.
According to pages 13 to 16 of page 101 of ``2017 edition,'' one handrail (7
) is stated to not stop even if it is pulled with a force of about 15 to 9.
このような手摺（７）の摩擦力に対し上記のような手摺
（７）に加わる力を考えると摩擦力を上まわり。Considering the frictional force of the handrail (7) as described above, the force applied to the handrail (7) exceeds the frictional force.
ステップ（５）は移動し続けるのに手摺（７）は停止若
しくはステップ（５）の速度よりも相当遅くなる。この
ため１手摺（７ンを把持している乗客が転倒して怪我を
するという問題があった。このため、ＦＦ開昭５８−１
７３６６８号公報に開示されたように停止させることも
考えられるが、やはり乗客に与える影響は大きい。Although step (5) continues to move, the handrail (7) either stops or becomes considerably slower than step (5). For this reason, there was a problem that passengers holding the 1 handrail (7) could fall and get injured.
Although it is possible to stop the vehicle as disclosed in Japanese Patent No. 73668, it still has a large impact on passengers.
この発明は上記問題に鑑みなされたもので、ステップと
手摺の動きを同期化し１手摺が停止した場合又は手摺の
速度が低下した場合、この手摺に合った速度でステップ
を制御することを目的とするものである。This invention was made in view of the above problem, and its purpose is to synchronize the movement of the steps and the handrail, so that when one handrail stops or the speed of the handrail decreases, the steps are controlled at a speed that matches that handrail. It is something to do.

It consists of a speed detector, and a speed control means that uses the speed of the handrail as a command signal from the movement speed detector that detects the speed of the moving means and controls the moving means by following this command signal.

~(21d) is closed. By this closing, the handrail motor rotates and the first handrail (7) moves in the upward direction. As a result of this movement, the handrail speed detector a generates an output, signals are output from the voltage reference setting circuit ae and the frequency reference setting circuit αη, and the inverter control circuit (18) increases the voltage and frequency according to this signal. A control signal is outputted from the inverter circuit (c) so that the phase order is as follows.The drive motor (1) is controlled by the inverter circuit a1 and moves in synchronization with the handrail (7).
