PROBLEM TO BE SOLVED: To provide an alignment device and an alignment method for metal plates capable of aligning two metal plates on a workbench with an error of 5 mm or less using an indoor crane, efficiently and safely.SOLUTION: A metal plate aligning method using a metal plate aligning device according to an embodiment of the invention comprises: radiating a rotary fan beam by a plurality of navigation transmitters 31 disposed in a work area for aligning two metal plates; receiving the rotary fan beam as IGPS signal by a navigation receiver 32 attached to a hoisting tool 21 of an indoor crane 2 for moving the metal plate locked by the hoisting tool 21; determining a current position of the hoisting tool 21 by a host computer 33 on the basis of the IGPS signal received by the navigation receiver 32; and autonomously moving the indoor crane 2 so that the current position of the hoisting tool 21 becomes a target position on the basis of a deviation between the determined current position and the target position to align the two metal plates.SELECTED DRAWING: Figure 2

    【課題】屋内クレーンによって2枚の金属板を5mm以内の誤差で作業台上に重ね合わせる作業において、効率的、且つ、安全に金属板を重ね合わせること。【解決手段】本発明の一実施形態である金属板の重ね合わせ装置では、2枚の金属板を重ね合わせる作業を行う作業エリア内に設けられた複数の航法用送信機31が、回転ファンビームを射出し、吊り治具21に金属板を係止することによって金属板を移動する屋内クレーン2の吊り治具21に装着された航法用受信機32が、回転ファンビームをIGPS信号として受信し、ホストコンピュータ33が、航法用受信機32が受信したIGPS信号に基づいて吊り治具21の現在位置を算出し、算出された現在位置と目標位置との偏差に基づいて吊り治具21の現在位置が目標位置になるように屋内クレーン2を自律走行させることによって、2枚の金属板を重ね合わせる。【選択図】図2
