WASHING METHOD OF PLATE-LIKE BODY

PROBLEM TO BE SOLVED: To provide a new washing method of a plate-like body which can efficiently wash dirt on both surfaces of the plate-like body, and does not require an excessive installation space.SOLUTION: A plate-like body 12 is supported in a standing state, washing water is discharged from nozzles 30 for discharging washing water to surfaces of both sides of the plate-like body 12, and positions of the nozzles 30 for discharging washing water to the plate-like body 12 are relatively moved in a length direction of the plate-like body 12 to wash the surfaces of both sides of the plate-like body 12. A washed area 28 of the plate-like body 12 between opposite parts of the nozzles 30 for discharging washing water arranged on both sides of the plate-like body 12 is opened not only in the length direction of the plate-like body 12 but also upward. Thereby, the plate-like body 12 and the nozzles 30 for discharging washing water are relatively moved in the length direction of the plate-like body 12 in a state that a lifting device 84 is attached to the plate-like body 12 from above, and the lifting device 84 is passed through an upward open part of the washed area 28 to wash both side surfaces of the plate-like body 12. 【課題】板状体の両面における汚れを効率的に洗滌することができると共に、設置スペースを過剰に必要としない、新規な板状体の洗滌方法を提供する。【解決手段】板状体１２を立てた状態で支持せしめて、洗滌水吐出用ノズル３０から板状体１２の両側表面に向けて洗滌水を吐出させつつ、板状体１２に対する洗滌水吐出用ノズル３０の位置を板状体１２の長さ方向で相対的に移動させて、板状体１２の両側表面を同時に洗滌すると共に、板状体１２の両側に配置された洗滌水吐出用ノズル３０の対向部間における板状体１２の洗滌領域２８を板状体１２の長さ方向だけでなく上方へも開放した領域として、板状体１２に対して上方からの吊上具８４を装着せしめたままの状態で、板状体１２と洗滌水吐出用ノズル３０とを板状体１２の長さ方向で相対的に移動させて、吊上具８４を洗滌領域２８の上方への開放部分を通過させることにより、板状体１２の両側面の洗滌を行う。【選択図】図１
