PROBLEM TO BE SOLVED: To provide a sill groove foreign object diagnosis device for elevator door having a function of removing a foreign object as much as possible which is caught in a sill groove and which hinders a door opening/closing operation.SOLUTION: In this device, a control panel 13 functions in cooperation with a door opening/closing position detection device 11 and a door control device 12. When the control panel 13 detects abnormality in which a foreign object is caught in a landing door side sill groove 8 and a car door side sill groove 9 of the sill 7 and a door opening/closing operation of an elevator door (a car door 4, a landing door 3) is hindered, in order that it can determine whether or not the foreign object can be removed based on a torque current value of a door motor 10 and a door opening/closing position from the door opening/closing position detection device 11, it gives an instruction to the door control device 12 to repeat door opening/closing operations continuously for the regulated number of times, and then it performs processing for determining the propriety of the door opening/closing operation. Also, after execution under a condition where the door cannot be closed, if a door inversion position changes and the door closing becomes possible, at the time point when it confirms a state in which the door opening/closing becomes normal, it regards the foreign object to have been moved and starts a normal service.SELECTED DRAWING: Figure 1
【課題】ドア開閉動作に支障を来す敷居溝に挟まった異物を可能な限り除去する機能を持つエレベータードア用敷居溝異物診断装置を提供する。【解決手段】この装置は、制御盤13がドア開閉位置検出装置11及びドア制御装置12と協働して機能するもので、制御盤13が敷居7の乗場ドア側敷居溝8やかごドア側敷居溝9に異物が挟まってエレベータードア(かごドア4、乗場ドア3)のドア開閉動作に支障を起こした異常を検知すると、ドアモータ10のトルク電流値とドア開閉位置検出装置11からのドア開閉位置とに基づいて異物の除去の可否を判定すべく、ドア制御装置12に指示してドア開閉動作を継続させて規定回数繰り返した後にドア開閉動作の可否を判定する処理を行う。また、ドア閉不可能な条件下で実施した後にドア反転位置が変化し、ドア閉可能となれば正常に開閉可能になった状態を確認した時点で異物が除去されたとみなして通常サービスを開始する。【選択図】図1
