| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a passenger conveyor device capable of recovering friction force between a drive roller and a moving handrail of a moving handrail drive part in an early stage when slip occurs.SOLUTION: A passenger conveyor device comprises: a moving handrail speed detector 12 for detecting moving speed of a moving handrail 8. When difference between operation control speed being target moving speed when the moving handrail 8 is driven and controlled, and actual speed being actual moving speed detected by the moving handrail speed detector 12 is equal to or more than a threshold, a control device 11 performs slip prevention control for repeating idling of a motor 10 and drive or braking of the moving handrail 8 by a drive roller 9.
【課題】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の提供。【解決手段】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を有し、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、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。【選択図】 図１ |
