To provide an abnormality detection system of a passenger conveyor which checks the presence or absence of abnormality of a wheel while driving so as to be able to cope with the abnormality before emergency stop is necessary.SOLUTION: An abnormality detection system of a passenger conveyor according to one embodiment has a plurality of steps, and wheels supporting these steps travel along a guide rail arranged within a truss, the system comprising a sensor, an inspection mechanism, and a control apparatus. The sensor detects the passage of each step at an inspection location set on the guide rail. The inspection mechanism presses the side face of wheels of each step with a predetermined force to inspect an inclination state of the wheels at the inspection location. The control apparatus determines the presence/absence of wheels of each step based on a detection timing of the sensor and an inspection result by the inspection mechanism.SELECTED DRAWING: Figure 4

    【課題】運転中に車輪の異常の有無を調べ、緊急停止が必要な状態になる前に対処可能とする。【解決手段】一実施形態に係る乗客コンベアの異常検出システムは、複数の踏段を有し、これらの踏段を支持する車輪がトラス内部に配設された案内レールに沿って走行する異常検出システムにおいて、センサと、検査機構と、制御装置とを備える。上記センサは、上記案内レール上に定められた検査箇所で上記各踏段の通過を検知する。上記検査機構は、上記検査箇所で上記各踏段の車輪の側面を軸方向に一定の力で押して、上記車輪の傾き状態を検査する。上記制御装置は、上記センサの検知タイミングと上記検査機構による検査結果とに基づいて、上記各踏段の車輪の異常の有無を判断する。【選択図】 図4
