Abstract
Description
本発明は、乗客コンベア装置に関する。 The present invention relates to a passenger conveyor device.
特許文献１には、無端状に連結され、乗降口間を循環移動する複数の踏段を駆動する踏段駆動部と、踏段と同期するように移動手摺を駆動する移動手摺駆動部とが別々に設けられた乗客コンベア装置において、踏段速度と移動手摺速度が同期していない状態を検出し、速度偏差に応じて速度補正処理を行うものが記載されている。この特許文献１には、踏板駆動機と手摺駆動機が別々に設けられた乗客コンベアにおいて、踏板速度および手摺速度に基づいて、踏板駆動機および手摺駆動機の駆動制御を行う際に、踏板速度検出器は、踏板速度に応じたパルス信号として位相の異なる２つの踏板速度用パルス信号を出力し、手摺速度検出器は、手摺速度に応じたパルス信号として位相の異なる２つの手摺速度用パルス信号を出力し、それぞれのパルス信号に基づいて、速度検出結果が正常であると判断した場合には、手摺速度と踏板速度とを一致させるように補正後の速度指令値を求め、手摺駆動機を駆動制御する比較制御装置を備えることが記載されている。 In Patent Document 1, a step drive unit that is connected endlessly and drives a plurality of steps that circulate between the entrances and exits, and a moving handrail drive unit that drives a moving handrail to synchronize with the steps are provided separately. In the passenger conveyor device described above, there is described a device that detects a state where the step speed and the moving handrail speed are not synchronized, and performs a speed correction process according to the speed deviation. In Patent Document 1, in a passenger conveyor in which a tread board driving machine and a handrail driving machine are separately provided, the tread board speed and the handrail driving machine are controlled based on the tread board speed and the handrail speed. The detector outputs two step board speed pulse signals having different phases as pulse signals corresponding to the step board speed, and the handrail speed detector includes two handrail speed pulse signals having different phases as pulse signals corresponding to the handrail speed. When the speed detection result is determined to be normal based on each pulse signal, a corrected speed command value is obtained so that the handrail speed matches the tread board speed, and the handrail driving machine is It is described that a comparison control device for driving control is provided.
ここで、前述した特許文献１に記載のものは、踏段速度と移動手摺速度が同期していない状態を検出し、速度偏差に応じて速度補正処理を行うものであるが、乗客コンベア装置にあっては、雨水によって移動手摺が濡れたり、移動手摺を把持する乗客の負荷により、移動手摺を駆動制御する際の目標の移動速度である運転制御速度と実際の移動速度である実状速度との間に閾値以上の差が生じるいわゆるスリップを起こすことがある。このようなスリップが生じ、駆動力が移動手摺に確実に伝わらない状態となると、踏段速度と移動手摺速度が同期しない事象が起こる。このような状態で前述した特許文献１に示すように、速度偏差に応じて速度補正処理を行っても、駆動力が移動手摺に伝わらないことから、速度補正を確実に行うことができなかった。したがって、スリップが生じた場合、まず移動手摺駆動部の駆動ローラと移動手摺との摩擦力を回復する必要があるという課題があった。 Here, the one described in Patent Document 1 described above detects a state in which the step speed and the moving handrail speed are not synchronized, and performs a speed correction process according to the speed deviation. In other words, when the moving handrail gets wet by rainwater or the load of the passenger gripping the moving handrail, the driving control speed that is the target moving speed when driving the moving handrail is controlled between the actual speed that is the actual moving speed. May cause a so-called slip in which a difference of more than a threshold value occurs. When such a slip occurs and the driving force is not reliably transmitted to the moving handrail, an event occurs in which the step speed and the moving handrail speed are not synchronized. In this state, as shown in Patent Document 1 described above, even if the speed correction process is performed according to the speed deviation, the driving force is not transmitted to the moving handrail, so that the speed correction cannot be reliably performed. . Therefore, when slip occurs, there is a problem that it is necessary to first recover the frictional force between the driving roller of the moving handrail driving unit and the moving handrail.
本発明は、前述した従来技術における実状からなされたもので、その目的は、スリップが生じた際、移動手摺駆動部の駆動ローラと移動手摺との摩擦力を早期に回復することのできる乗客コンベア装置を提供することにある。 The present invention has been made from the state of the prior art described above, and its purpose is a passenger conveyor that can quickly recover the frictional force between the driving roller of the moving handrail drive unit and the moving handrail when slipping occurs. To provide an apparatus.
前記目的を達成するために、本発明は、例えば、無端状に連結され、乗降口間を循環移動する複数の踏段と、前記複数の踏段を駆動する踏段駆動部と、前記踏段の進行方向に沿って立設される欄干と、前記欄干により支持され、前記踏段と同期して移動する移動手摺と、前記移動手摺に当接する駆動ローラ及び前記駆動ローラを駆動するモータを有する移動手摺駆動部と、前記移動手摺駆動部を制御する制御装置とを備えた乗客コンベア装置において、前記移動手摺の移動速度を検出する移動手摺速度検出器を有し、前記制御装置は、前記移動手摺を駆動制御する際の目標の移動速度である運転制御速度と前記移動手摺速度検出器によって検出された実際の移動速度である実状速度との間に閾値以上の差を検出した場合、前記モータの空転と前記駆動ローラによる前記移動手摺の駆動又は制動とを繰り返すスリップ防止制御を行うことを特徴としている。 In order to achieve the above object, the present invention is, for example, connected endlessly, a plurality of steps that circulate and move between entrances, a step drive unit that drives the plurality of steps, and a direction in which the steps travel. A balustrade erected along, a moving handrail supported by the balustrade and moving in synchronization with the step, a moving handrail driving unit having a driving roller that contacts the moving handrail and a motor that drives the driving roller; A passenger conveyor device having a control device for controlling the moving handrail driving unit, and a moving handrail speed detector for detecting a moving speed of the moving handrail, wherein the control device drives and controls the moving handrail. If a difference of more than a threshold value is detected between the operation control speed, which is the target moving speed at the time, and the actual speed, which is the actual moving speed detected by the moving handrail speed detector, Is characterized by performing a slip prevention control by serial driving roller repeats the driving or braking of the moving handrail.
本発明によれば、移動手摺の運転制御速度と実状速度との間に閾値以上の差が生じるいわゆるスリップを検出すると、制御装置は、移動手摺駆動部のモータの空転と駆動ローラによる移動手摺の駆動又は制動とを繰り返すスリップ防止制御を行い、駆動ローラと移動手摺との摩擦力を早期に回復し、移動手摺を所望の速度で駆動することを可能とし、これによって、踏段速度と移動手摺速度とを確実に同期させることができる。 According to the present invention, when detecting a so-called slip in which a difference greater than or equal to a threshold value is detected between the operation control speed and the actual speed of the moving handrail, the control device causes the motor of the moving handrail driving unit to idle and the moving handrail by the driving roller. Anti-slip control that repeats driving or braking is performed, the frictional force between the driving roller and the moving handrail is recovered early, and the moving handrail can be driven at a desired speed. Can be reliably synchronized.
本発明の実施例を、図面を参照しながら説明する。尚、各図において、同一又は類似の構成要素には同じ符号を付し、説明を省略する。 Embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or similar components are denoted by the same reference numerals and description thereof is omitted.
本実施例の乗客コンベア装置は、図１に示すように、無端状に連結され、乗降口間を循環移動する複数の踏段１と、上部機械室２に設置される踏段駆動機３と、踏段駆動機３のシーブ３ａに巻回される駆動チェーン４と、駆動チェーン４が巻回される第１スプロケット５ａ、及び踏段チェーン６が巻回される第２スプロケット５ｂを有してなる駆動スプロケット５とを備えており、踏段駆動機３、駆動チェーン４、駆動スプロケット５及び踏段チェーン６で踏段１を駆動する踏段駆動部を構成しており、踏段駆動機３の動力が駆動チェーン４、駆動スプロケット５及び踏段チェーン６を介して踏段１に伝えられ、踏段１は乗降口間を循環移動するようになっている。 As shown in FIG. 1, the passenger conveyor device of the present embodiment is connected endlessly, and a plurality of steps 1 that circulate between the entrances and exits, a step driver 3 installed in the upper machine room 2, and steps A drive sprocket 5 having a drive chain 4 wound around a sheave 3a of the drive machine 3, a first sprocket 5a around which the drive chain 4 is wound, and a second sprocket 5b around which a step chain 6 is wound. The step drive unit 3 drives the step 1 with the step drive machine 3, the drive chain 4, the drive sprocket 5 and the step chain 6, and the power of the step drive machine 3 is driven by the drive chain 4 and the drive sprocket. 5 and the step chain 6 are transmitted to the step 1 so that the step 1 circulates between the entrances and exits.
また、乗客コンベア装置は、踏段１の進行方向に沿って立設される欄干７と、この欄干７により支持され、踏段１と同期して移動する移動手摺８と、この移動手摺８に当接する駆動ローラ９と、この駆動ローラ９を駆動するモータ１０を備えており、これらの駆動ローラ９及びモータ１０で移動手摺駆動部を構成しており、モータ１０の動力が駆動ローラ９を介して移動手摺８に伝えられ、移動手摺８は乗降口間を循環移動するようになっている。尚、移動手摺駆動部の動力であるモータ１０は、踏段駆動機３の動力であるモータとは別に設けられたものである。 Further, the passenger conveyor device abuts against the balustrade 7 that is erected along the direction of travel of the step 1, the moving handrail 8 that is supported by the balustrade 7 and moves in synchronization with the step 1, and the moving handrail 8. A driving roller 9 and a motor 10 for driving the driving roller 9 are provided. The driving roller 9 and the motor 10 constitute a moving handrail driving unit, and the power of the motor 10 moves through the driving roller 9. The handrail 8 is transmitted to the handrail 8 so as to circulate between the entrances and exits. Note that the motor 10 that is the power of the moving handrail drive unit is provided separately from the motor that is the power of the step driver 3.
なお、前述した踏段駆動部及び移動手摺駆動部を含め、乗客コンベア装置は制御装置１１により統括制御されている。 In addition, the passenger conveyor device including the step driving unit and the moving handrail driving unit described above is comprehensively controlled by the control device 11.
そして、本実施例の乗客コンベア装置は、スリップが生じた際、移動手摺駆動部の駆動ローラ９と移動手摺８との摩擦力を早期に回復するために工夫がなされている。具体的には、移動手摺８の移動速度を検出する移動手摺速度検出器１２を設け、制御装置１１は、移動手摺８を駆動制御する際の目標の移動速度である運転制御速度と移動手摺速度検出器１２によって検出された実際の移動速度である実状速度との間に閾値以上の差を検出した場合（すなわちスリップが生じた場合）、モータ１０の空転と駆動ローラ９による移動手摺８の駆動又は制動とを繰り返すスリップ防止制御を行うようになっている。 And the passenger conveyor apparatus of a present Example is devised in order to recover the frictional force of the drive roller 9 of the moving handrail drive part and the moving handrail 8 at an early stage when a slip occurs. Specifically, a moving handrail speed detector 12 that detects the moving speed of the moving handrail 8 is provided, and the control device 11 controls the operation control speed and the moving handrail speed, which are target moving speeds when driving the moving handrail 8. When a difference equal to or greater than a threshold value is detected between the actual moving speed detected by the detector 12 (ie, when slipping occurs), the motor 10 idles and the driving roller 9 drives the moving handrail 8. Or slip prevention control which repeats braking is performed.
本実施例にあっては、図２の手順Ｓ１に示すように、制御装置１１は、移動手摺駆動部に運転制御速度指令を出力、すなわちあるべき速度（目標の移動速度）による運転を指令すると共に、手順Ｓ２に示すように、移動手摺８のスリップを監視している。すなわち、手順Ｓ２に示すように、運転制御速度と移動手摺速度検出器１２により検出される実状速度との差が閾値を越えたかどうかを判断している。そして、例えば雨水により移動手摺が濡れることなどにより、駆動ローラ９と移動手摺８との間の摩擦係数が低下して、移動手摺８の運転制御速度と実状速度との間に閾値以上の差が生じたことを検出すると、手順Ｓ３として、制御装置１１は、運転制御速度指令を微小な一定時間、停止、もしくはフリーランにし、次いで、手順Ｓ４として、運転制御速度指令を微小な一定時間、出力する。これらの手順Ｓ３及び手順Ｓ４がスリップ防止制御となるが、移動手摺８の実状速度が運転制御速度より遅くなるスリップの場合、モータ１０（駆動ローラ９）の空転と駆動ローラ９による移動手摺８の駆動を繰り返すスリップ防止制御が行われ、一方、移動手摺８の実状速度が運転制御速度より早くなるスリップの場合、モータ１０（駆動ローラ９）の空転と駆動ローラ９による移動手摺８の制動を繰り返すスリップ防止制御が行われる。このスリップ防止制御は、運転制御速度と移動手摺速度検出器１２により検出される実状速度との差が閾値以内となるまで続けられるが、手順Ｓ３と手順Ｓ４との間にも手順Ｓ２と同様の処理、すなわち運転制御速度と移動手摺速度検出器１２により検出される実状速度との差が閾値を越えたかどうかを判断する手順Ｓ３ａを含め、より細かな制御を行うようにしても良い。なお、これら一連の制御は手順Ｓ５で示す運転停止指令が出力されるまで継続されるものである。 In the present embodiment, as shown in step S1 of FIG. 2, the control device 11 outputs an operation control speed command to the moving handrail drive unit, that is, instructs operation at a desired speed (target moving speed). At the same time, as shown in step S2, the slip of the moving handrail 8 is monitored. That is, as shown in step S2, it is determined whether or not the difference between the operation control speed and the actual speed detected by the moving handrail speed detector 12 exceeds a threshold value. Then, for example, when the moving handrail is wetted by rain water, the friction coefficient between the driving roller 9 and the moving handrail 8 is reduced, and there is a difference greater than the threshold between the operation control speed and the actual speed of the moving handrail 8. When it is detected that the occurrence has occurred, in step S3, the control device 11 stops or free-runs the operation control speed command for a minute fixed time, and then outputs the operation control speed command for a minute fixed time in step S4. To do. These steps S3 and S4 are anti-slip control, but in the case of a slip in which the actual speed of the moving handrail 8 is slower than the operation control speed, the motor 10 (driving roller 9) idles and the moving handrail 8 is driven by the driving roller 9. Anti-slip control that repeats driving is performed. On the other hand, if the slip is such that the actual speed of the moving handrail 8 is faster than the operation control speed, the motor 10 (driving roller 9) idles and braking of the moving handrail 8 by the driving roller 9 is repeated. Anti-slip control is performed. This anti-slip control is continued until the difference between the operation control speed and the actual speed detected by the moving handrail speed detector 12 falls within the threshold, but the same as in step S2 between step S3 and step S4. More detailed control may be performed including processing, that is, step S3a for determining whether or not the difference between the operation control speed and the actual speed detected by the moving handrail speed detector 12 exceeds the threshold value. The series of controls is continued until the operation stop command shown in step S5 is output.
本実施例によれば、移動手摺の運転制御速度と実状速度との間に閾値以上の差が生じるいわゆるスリップを検出すると、制御装置１１は、移動手摺駆動部のモータ１０（駆動ローラ９）の空転と駆動ローラ９による移動手摺８の駆動又は制動とを繰り返すスリップ防止制御を行い、駆動ローラ９と移動手摺８との摩擦力を早期に回復し、移動手摺８を所望の速度で駆動することを可能とし、これによって、踏段速度と移動手摺速度とを確実に同期させることができる。 According to the present embodiment, when detecting a so-called slip in which a difference equal to or greater than a threshold value is detected between the operation control speed and the actual speed of the moving handrail, the control device 11 causes the motor 10 (driving roller 9) of the moving handrail driving unit. Anti-slip control that repeats idling and driving or braking of the moving handrail 8 by the driving roller 9 is performed, the frictional force between the driving roller 9 and the moving handrail 8 is recovered early, and the moving handrail 8 is driven at a desired speed. Thus, the step speed and the moving handrail speed can be reliably synchronized.
