To provide an unmanned fork lift charging system capable of suppressing reduction of a truck operation rate.SOLUTION: A charging system 1 comprises: a truck 10 transmitting own vehicle positional information; an unmanned fork lift 20 for performing a plurality of pieces of cargo handling work, and loading and unloading work to the truck 10 which arrives at a prescribed place P; an arrival time estimating part for estimating arrival time of the truck 10 to the prescribed place P; a work schedule time calculating part for calculating loading and unloading work schedule time when, loading and unloading work is performed; a remaining battery estimating a remaining battery of the unmanned fork lift 20 at the loading and unloading work schedule time; a charging station 30 for charging; and a schedule generating part for generating a charging schedule when the estimated remaining battery becomes equal to or lower than a predetermined prescribed amount, in which the unmanned fork lift 20 recovers the remaining battery according to the charging schedule, and after recovering so that, the remaining battery does not become equal to or lower than the predetermined constant amount during the loading and unloading work, then, performs loading and unloading work.SELECTED DRAWING: Figure 1

    【課題】トラックの稼働率の低下を抑制できる無人フォークリフト用充電システムを提供する。【解決手段】充電システム1は、自車の位置情報を送信するトラック10、複数の荷役作業と所定地Pに到着したトラック10に対して積み卸し作業とを行う無人フォークリフト20、所定地Pへのトラック10の到着時刻を推定する到着時刻推定部、積み卸し作業が行われる積み卸し作業予定時間を算出する作業予定時間算出部、積み卸し作業予定時間における無人フォークリフト20のバッテリ残量を推定するバッテリ残量推定部、充電を行う充電ステーション30、および、推定バッテリ残量が予め定められた所定量以下になるとき充電スケジュールを生成するスケジュール生成部を備え、無人フォークリフト20は、充電スケジュールに従ってバッテリ残量を回復させ、バッテリ残量が積み卸し作業の間に予め定められた一定量以下にならないように回復した後、積み卸し作業を行う。【選択図】図1
