Description

【0001】
【発明の属する技術分野】
この発明は、主枠に設けられた多数の踏板が無端状に連結されて循環運転される乗客コンベヤーの制動試験方法に関する。
【0002】
【従来の技術】
図9及び図10は、エスカレーターからなる乗客コンベヤーを示す図で、図9は乗客コンベヤーの長手端部を概念的に示す縦断面図、図10は図9のA−A線断面拡大図である。図において、1は乗客コンベヤーの主枠、2は主枠1の長手端部に設けられた機械室、3は多数の踏板4が無端状に連結されてなり主枠1に配置されて循環運転される搬送帯、5は機械室2に設けられて搬送帯3が巻掛けられた鎖歯車である。
【0003】
6は機械室2に設けられて巻掛伝動機構7及び鎖歯車5によって搬送帯3を駆動する駆動機で、電動機8、電動機8の出力軸を制動する制動機9、電動機8の出力軸に連結された減速機10、減速機10の出力軸に固定された巻掛伝動機構7の駆動車11、電動機8の出力軸の反制動機9側の端部に締結された弾み車12が設けられている。
【0004】
上記のように構成された乗客コンベヤーにおいて従来、次に述べるようにして乗客コンベヤーの制動試験が行われていた。すなわち、駆動機6の制動機9の動作試験として、搬送帯3の荷重が無負荷であって上昇運転中及び下降運転中のそれぞれにおける停止距離測定、搬送帯3に所定荷重が作用した状態であって上昇運転中及び下降運転中のそれぞれにおける停止距離測定が実施される。
なお、乗客コンベヤーの非常停止時に、踏板4上の乗客が転倒しないように緩やかな減速度で制動動作するように弾み車12が設けられている。
【0005】
【発明が解決しようとする課題】
上記のような従来の乗客コンベヤーの制動試験方法では、搬送帯3に所定荷重が作用した状態、すなわち乗客コンベヤーの定格積載荷重に対応した制動機9の動作時の停止距離測定において、踏板4のそれぞれに120キログラム程度の負荷を載置することになる。したがって、例えば階高4メートル、踏板の幅1.2メートルのエスカレーターに所定荷重が作用した状態とするためには、合計2トンもの錘等を載置することになって、多大な労力と時間を要するという問題点があった。
【0006】
この発明は、かかる問題点を解消するためになされたものであり、煩雑な手数を要せずに制動機作動時における搬送帯の運転方向及び負荷状態に対応した停止距離が測定できる乗客コンベヤーの制動試験方法を得ることを目的とする。
【0007】
【課題を解決するための手段】
この発明に係る乗客コンベヤーの制動試験方法においては、多数の踏板が無端状に連結されてなり主枠に配置されて循環運転される搬送帯と、電動機及び制動機が設けられて上記主枠に装備され上記搬送帯を駆動する駆動機と、電動機の出力軸に固定されたフランジ付スリーブと、円盤状をなし中心部がフランジ付スリーブの外径に嵌合されて電動機の出力軸に設けられる複数個の弾み車とを備えた乗客コンベヤーにおいて、上記乗客コンベヤーの制動試験時に、上記弾み車の数を増減させることにより、試験諸元に対応した等価量の弾み車を上記電動機の出力軸に仮設される。
【0008】
また、この発明に係る乗客コンベヤーの制動試験方法においては、スリーブのフランジ面に一端が固定されて長手がスリーブの外面に沿って配置された取付ボルトと、取付ボルトの先端にねじ込まれるナットにより、複数個の弾み車を互いに重合状態に締結される
【0009】
また、この発明に係る乗客コンベヤーの制動試験方法においては、弾み車が、中心部がフランジ付スリーブの外径に少ない隙間で嵌合された芯合わせ部を介して電動機の出力軸に仮設される。
【0010】
また、この発明に係る乗客コンベヤーの制動試験方法においては、弾み車が、相互の重合面に設けられて互いに嵌合する凸部及び凹部からなる対向面芯合わせ部を介して重合状態に配置して仮設される。
【0011】
また、この発明に係る乗客コンベヤーの制動試験方法においては、駆動機を、電動機の出力軸が鉛直方向に配置された縦型とし、弾み車を、相互の対向面に設けられた対向面芯合わせ部を介して重合状態に配置して上記鉛直方向の出力軸に水平姿勢に仮設し、上側の弾み車の下面から下方へ突設されて下側の弾み車及び上記出力軸部材の貫通孔に空隙を形成して挿通して配置されて弾み車相互の水平方向変位を阻止する係合ピンが設けられる。
【0012】
【発明の実施の形態】
実施の形態1.
図1〜図5は、この発明の実施の形態の一例を示す図で、図1は前述の図10相当図、図2は弾み車の通常運転時の状態を示す図1のB部拡大断面図、図3は弾み車の仮設状態を示す図1のB部拡大断面図、図4は弾み車の他の仮設状態を示す図1のB部拡大断面図、図5は乗客コンベヤーの制動試験における制動速度と時間の関係を示すグラフである。なお、図1〜図5の他は前述の図9及び図10と同様に乗客コンベヤーが構成されている。図において、1は乗客コンベヤーの主枠、2は主枠1の長手端部に設けられた機械室である。
【0013】
6は機械室2に設けられて搬送帯3を駆動する駆動機で、電動機8、電動機8の出力軸を制動する制動機9、電動機8の出力軸13に連結された減速機10、減速機10の出力軸に固定された巻掛伝動機構7の駆動車11が設けられている。また、14は電動機8の出力軸13の反制動機9側の端部に焼きばめされて固定されたフランジ付のスリーブである。
【0014】
15は取付ボルトで、フランジ側面の互いに対向位置に設けられ、スリーブ14のフランジ面に一端が固定されて長手がスリーブ14の外面に沿って配置されている。16は円盤状をなし中心部がスリーブ14の外径に少ない隙間で嵌合された芯合わせ部17が形成された弾み車で、後述する適宜な数が互いに重合状態に出力軸13と同芯に配置されると共に、取付ボルト15に空隙を形成して嵌合されて制動試験時に仮設される。18は取付ボルト15の先端にねじ込まれて弾み車16をスリーブ14に締結するナットである。
【0015】
上記のように構成された乗客コンベヤーにおいて、通常運転時には図2に示すようにスリーブ14を介して三個の弾み車16が電動機8の出力軸13に配置されて、取付ボルト15及びナット18によって締結される。これにより、乗客コンベヤーの非常停止時に、踏板4上の乗客が転倒しないような緩やかな減速度による制動動作が得られる。
【0016】
そして、乗客コンベヤーの制動試験時には、試験諸元に対応した等価量の弾み車16が電動機8の出力軸13に仮設される。これにより、図3に示すように弾み車16数を減少して乗客コンベヤーの制動時に停止距離を短くし、図4に示すように弾み車16数を追加して乗客コンベヤーの制動時に停止距離を長くすることができる。
【0017】
以下、搬送帯3に所定荷重が作用した状態、すなわち乗客コンベヤーの定格積載荷重による制動負荷に対する制動機9動作時の停止距離とするための弾み車16量を求める。すなわち、乗客コンベヤーの無負荷時の制動機9動作による停止距離SN 、乗客コンベヤーの制動負荷時の制動機9動作による停止距離SB は図5に示すようになり次の算式によって表される。

ただし、上記各GD2 、トルク及び回転速度は電動機8軸における数値に換算した値である。
【0022】
なお、前述の(式1−1)及び(式1−2)において、制動負荷を積載することにより乗客コンベヤーの停止距離が変化するのは、乗客コンベヤーの制動時間t1 がt'1U 及びt'1D に変化するためである。すなわち、無負荷状態において制動負荷時の乗客コンベヤーの停止距離を測定するためには、前述の(式1−3)(式1−4)及び(式1−5)により弾み車16数を加減し、乗客コンベヤーのGD2 をGD2 E から上昇運転時に

【0023】
例えば、GD2 、トルク及び回転速度が上記の各数値が適用される乗客コンベヤーについて考察すると、無負荷時及び制動負荷時の上昇、下降について制動時間t1 、t'1U 及びt'1D はそれぞれ次のようになる。
【0024】
【数7】

【0025】
そして、無負荷状態において制動負荷時相当の乗客コンベヤーの停止距離試験の制動時間をそれぞれt'1Ut 、t'1Dt とし、乗客コンベヤーのGD2 を上昇運転時に

上記より、制動負荷時及び制動負荷時相当の乗客コンベヤーの制動時間は、
【0027】
【数11】
Figure 0003752380
となり、また(式1−2)より制動負荷が作用した時と制動負荷時相当の乗客コンベヤーの停止距離とが等しくなる。これにより、無負荷状態において弾み車16量を加減して乗客コンベヤーのGD2 を変化させることによって、制動負荷が作用した時相当の乗客コンベヤーの停止距離の測定できることがわかる。
また、前述の制動時間を求めた乗客コンベヤーについて弾み車16量を加減させるGD2 、GD2 U 及びGD2 D を計算すると次のようになる。
【0028】
【数12】
Figure 0003752380
【0029】
例えば、乗客コンベヤーに外径400mm、内径70mmの鉄製の弾み車16を設けたとすると、加減する弾み車16の厚さ上昇運転時T U 、下降運転時T D は、
【0030】

また、同様に弾み車16の質量は上昇運転時M U 、下降運転時M D とし、
【0031】
【数14】
Figure 0003752380
となる。したがって、僅か10kg、20kg程度の弾み車16を設けることによって、制動負荷が作用した状態と等価的な制動機9作動時の停止距離を測定することができる。
これにより、踏板4のそれぞれに120キログラム程度の負荷を載置して制動負荷とし、制動機9作動時の停止距離を測定する手数を省くことができる。
【0032】
このようにして、乗客コンベヤーの制動試験時に、試験諸元に対応した等価量の弾み車16が電動機8の出力軸13に仮設される。そして、この無負荷状態の乗客コンベヤーを運転して、制動機9が作動したときの制動負荷時相当の停止距離が測定される。したがって、煩雑な手数を要せず容易に乗客コンベヤーの制動試験を行うことができ、制動試験の作業能率を向上することができる。
【0033】
また、複数の弾み車16が互いに重合状態に配置されて出力軸13に設けられたスリーブ14に仮設される。このため、弾み車16数を加減して仕様の異なる乗客コンベヤー又は制動試験時の異なる試験諸元に容易に対応することができる。したがって、所定のGD2 の弾み車16の複数個を準備することによって異なる試験諸元等に使用でき、制動試験の作業能率を向上することができる。
【0034】
また、弾み車16に芯合わせ部17が形成されているので、複数の弾み車16を出力軸13に設けられたスリーブ14に容易に芯合わせすることができる。このため、弾み車16数を加減したときに駆動機6の回転バランスを保ことができ、特別な調整が不要であって制動試験の作業能率を向上することができる。
【0035】
実施の形態2.
図6は、この発明の他の実施の形態の一例を示す図で、前述の図2相当図である。なお、図6の他は前述の図1〜図5の実施の形態と同様に乗客コンベヤーが構成されている。図において、図1〜図5と同符号は相当部分を示し、19は弾み車16相互の重合面に設けられて互いに嵌合する凸部及び凹部からなる対向面芯合わせ部である。
【0036】
上記のように構成された乗客コンベヤーにおいても、前述の図1〜図5の実施の形態と同様に、乗客コンベヤーの制動試験時に試験諸元に対応した等価量の弾み車16が電動機8の出力軸13にスリーブ14を介し仮設され、また弾み車16に芯合わせ部17が形成されている。したがって、詳細な説明を省略するが図6の実施の形態においても図1〜図5の実施の形態と同様な作用が得られる。
【0037】
また、図6の実施の形態において、対向面芯合わせ部19が設けられているので、弾み車16の相互を出力軸13に設けられたスリーブ14に対して容易に芯合わせすることができる。このため、出力軸13端からのスリーブ14の突出量を少なくすることができ、機械室2の所要スペース節減することができる。
【0038】
実施の形態3.
図7及び図8も、この発明の他の実施の形態の一例を示す図で、図7は前述の図1相当図、図8は弾み車の仮設状態を示す図7のC部拡大断面図である。なお、図7及び図8の他は前述の図1〜図5と同様に乗客コンベヤーが構成されている。図において、図1〜図5及び図6と同符号は相当部分を示す。
【0039】
6は縦型の駆動機、16は水平に配置された弾み車で、下側の一つが芯合わせ部17により出力軸13に設けられたスリーブ14に嵌合されて、その上に複数個が重合されて対向面芯合わせ部19により相互に同芯に配置されている。20は上側の弾み車16の下面から下方へ突設された係合ピンで、下側の弾み車16及びスリーブ14の貫通孔に空隙を形成して挿通して配置されて弾み車16相互の水平方向変位を阻止する。
【0040】
上記のように構成された乗客コンベヤーにおいても、前述の図1〜図5の実施の形態、図6の実施の形態と同様に、乗客コンベヤーの制動試験時に試験諸元に対応した等価量の弾み車16が電動機8の出力軸13に仮設され、また弾み車16に芯合わせ部17及び対向面芯合わせ部19が形成されている。したがって、詳細な説明を省略するが図7及び図8の実施の形態においても図1〜図4の実施の形態、図6の実施の形態と同様な作用が得られる。
【0041】
また、図7及び図8の実施の形態において、縦型の駆動機6の鉛直に配置された出力軸13に対し、弾み車16が水平に配置されて係合ピン20により弾み車16相互の水平方向変位が阻止される。これにより、弾み車16の仮設時に弾み車16を取付ボルト15及びナット18によって締結する必要がなく、乗客コンベヤーの制動試験時に弾み車16を容易に着脱することができる。したがって、煩雑な手数を要せず容易に乗客コンベヤーの制動試験を行うことができ制動試験の作業能率を向上することができる。
【0042】
【発明の効果】
この発明は以上説明したように、多数の踏板が無端状に連結されてなり主枠に配置されて循環運転される搬送帯と、電動機及び制動機が設けられて上記主枠に装備され上記搬送帯を駆動する駆動機と、電動機の出力軸に固定されたフランジ付スリーブと、円盤状をなし中心部がフランジ付スリーブの外径に嵌合されて電動機の出力軸に設けられる複数個の弾み車とを備えた乗客コンベヤーにおいて、上記乗客コンベヤーの制動試験時に、上記弾み車の数を増減させることにより、試験諸元に対応した等価量の弾み車を上記電動機の出力軸に仮設して運転し制動機作動時の停止距離を測定するものである。
【0043】
これによって、乗客コンベヤーの踏板のそれぞれに120キログラム程度の制動負荷荷重を載置することなく、制動負荷と等価的な制動機作動時の停止距離を測定することができる。したがって、煩雑な手数を要せず容易に乗客コンベヤーの制動試験を行うことができ制動試験の作業能率を向上する効果がある。
【0044】
また、この発明は以上説明したように、スリーブのフランジ面に一端が固定されて長手がスリーブの外面に沿って配置された取付ボルトと、取付ボルトの先端にねじ込まれるナットにより、複数個の弾み車を互いに重合状態に締結するものである。
【0045】
これによって、弾み車数を加減して仕様の異なる乗客コンベヤー又は制動試験時の異なる試験諸元に容易に対応することができる。したがって、所定のGD2 の弾み車の複数個を準備することによって異なる試験諸元等に使用することができ、制動試験の作業能率を向上する効果がある。
【0046】
また、この発明は以上説明したように、弾み車を、中心部がフランジ付スリーブの外径に少ない隙間で嵌合された芯合わせ部を介して電動機の出力軸に仮設したものである。
【0047】
これによって、弾み車を芯合わせ部を介して電動機の出力軸に容易に芯合わせすることができる。このため、弾み車の仮設時の駆動機の回転バランスを保つことができ、特別な調整を要せず制動試験の作業能率を向上する効果がある。
【0048】
また、この発明は以上説明したように、弾み車を、相互の重合面に設けられて互いに嵌合する凸部及び凹部からなる対向面芯合わせ部を介して重合状態に配置して仮設したものである。
【0049】
これによって、対向面芯合わせ部により複数の弾み車の相互を、芯合わせ状態に配置できる。したがって、電動機の出力軸部材の突出量を少なくすることができ、機械室の所要スペース節減する効果がある。
【0050】
また、この発明は以上説明したように、駆動機を、電動機の出力軸が鉛直方向に配置された縦型とし、弾み車を、相互の対向面に設けられた対向面芯合わせ部を介して重合状態に配置して上記鉛直方向の出力軸に水平姿勢に仮設し、上側の弾み車の下面から下方へ突設されて下側の弾み車及び上記出力軸部材の貫通孔に空隙を形成して挿通して配置されて弾み車相互の水平方向変位を阻止する係合ピンを設けたものである。
【0051】
これによって、縦型の駆動機に対して弾み車が水平に配置され、係合ピンにより弾み車相互の水平方向変位が阻止されるので、弾み車の仮設時に弾み車を締結する必要がなく、乗客コンベヤーの制動試験時に弾み車を容易に着脱することができる。したがって、煩雑な手数を要せず容易に乗客コンベヤーの制動試験を行うことができ制動試験の作業能率を向上する効果がある。

Reference numeral 18 denotes a nut that is screwed into the tip of the mounting bolt 15 to fasten the spring wheel 16 to the sleeve 14.
[0015]
In the passenger conveyor configured as described above, in the normal operation, as shown in FIG. 2, three spring wheels 16 are arranged on the output shaft 13 of the electric motor 8 via the sleeve 14 and fastened by the mounting bolt 15 and the nut 18. Is done. Thereby, at the time of an emergency stop of a passenger conveyor, the braking operation | movement by the gentle deceleration that the passenger on the tread board 4 does not fall is obtained.
[0016]
In the braking test of the passenger conveyor, an equivalent amount of the flywheel 16 corresponding to the test specifications is temporarily installed on the output shaft 13 of the electric motor 8. As a result, the number of flywheels 16 is reduced as shown in FIG. 3 to shorten the stop distance when the passenger conveyor is braked, and the number of flywheels 16 is added as shown in FIG. 4 to increase the stop distance when the passenger conveyor is braked. be able to.
[0017]
Hereinafter, the amount of the flywheel 16 for obtaining the stop distance when the brake 9 is operated with respect to the braking load caused by the rated load on the passenger conveyor, that is, the state in which the predetermined load is applied to the transport belt 3 is obtained. That is, the stop distance S N due to the operation of the brake 9 when the passenger conveyor is not loaded and the stop distance S B due to the operation of the brake 9 when the passenger conveyor is loaded are as shown in FIG. .

r 0 : Brake shaft rotation speed at the initial speed (v 0 ) (eg r 0 = 1500 rpm)
However, each GD 2 , torque, and rotational speed are values converted into numerical values for the 8-axis motor.
[0022]
In addition, in the above-described (Formula 1-1) and (Formula 1-2), the stopping distance of the passenger conveyor is changed by loading the braking load because the braking time t 1 of the passenger conveyor is t ′ 1U and t 'Because it changes to 1D . In other words, in order to measure the stopping distance of the passenger conveyor at the time of braking load in the no-load state, the number of the flywheels 16 is adjusted by the above-described (Expression 1-3) (Expression 1-4) and (Expression 1-5). When driving up the passenger conveyor GD 2 from GD 2 E

And at the time of descent operation
Figure 0003752380
Thus, the required measurement can be performed.
[0023]
For example, considering a passenger conveyor to which the above values are applied for GD 2 , torque and rotational speed, the braking time t 1 , t ′ 1U and t ′ 1D for rising and falling at no load and braking load are respectively It becomes as follows.
[0024]

## EQU11 ##
Figure 0003752380
Also, from (Equation 1-2), when the braking load is applied, the stopping distance of the passenger conveyor corresponding to the braking load becomes equal. Accordingly, it can be seen that by changing the GD 2 of the passenger conveyor by adjusting the amount of the flywheel 16 in the no-load state, the stop distance of the passenger conveyor can be measured when the braking load is applied.
Further, when GD 2 , GD 2 U and GD 2 D for adjusting the amount of the flywheel 16 are calculated for the passenger conveyor for which the above-described braking time is obtained, it is as follows.
[0028]
[Expression 12]
Figure 0003752380
[0029]
For example, the outer diameter 400mm passengers conveyor, when provided with iron flywheel 16 of internal diameter 70 mm, thickness-increasing operation time T U of the flywheel 16 to moderate, decreasing operation time T D is
[0030]
[Formula 13]

Similarly, the mass of the flywheel 16 and the torque-increasing operation time of M U, decreasing operation when M D,

It becomes. Accordingly, by providing the flywheel 16 of only 10 kg or 20 kg, it is possible to measure the stop distance when the brake 9 is operated, which is equivalent to the state in which the braking load is applied.
As a result, a load of about 120 kilograms can be placed on each of the treads 4 as a braking load, and the trouble of measuring the stopping distance when the brake 9 is actuated can be saved.
[0032]
In this way, during the passenger conveyor braking test, an equivalent amount of the flywheel 16 corresponding to the test specifications is temporarily installed on the output shaft 13 of the electric motor 8. Then, the passenger conveyor in the unloaded state is operated, and the stopping distance corresponding to the braking load when the brake 9 is activated is measured. Therefore, it is possible to easily perform a braking test on the passenger conveyor without requiring a complicated operation, and to improve the work efficiency of the braking test.

For this reason, it is possible to easily cope with passenger conveyors having different specifications or different test specifications at the time of a braking test by adjusting the number of the flywheels 16. Therefore, by preparing a plurality of predetermined GD 2 flywheels 16, they can be used for different test specifications and the like, and the work efficiency of the braking test can be improved.
[0034]
In addition, since the centering portion 17 is formed in the spring wheel 16, the plurality of spring wheels 16 can be easily centered on the sleeve 14 provided on the output shaft 13. For this reason, the rotational balance of the drive unit 6 can be maintained when the number of the flywheels 16 is adjusted, no special adjustment is required, and the work efficiency of the braking test can be improved.
