Description
図1は、第1実施形態に係る搬送車システム1の構成図である。搬送車システム1は、軌道に沿って移動可能な天井走行車40を用いて、被搬送物Xを搬送するためのシステムである。ここでは、例えば、工場などにおいて、被搬送物である一般物品を移載可能に構成された無人の天井走行車が軌道に沿って走行する搬送車システムを例に挙げて説明する。なお、被搬送物の例には、半導体ウェハ、ガラス基板及び一般部品などが含まれる。図1に示すように、搬送車システム1は、主に管理コントローラ3、軌道11、給電部21及び天井走行車(搬送車)40を備えている。
次に、第2実施形態について主に図3を参照しながら説明する。図3は、第2実施形態に係る搬送車システム101の構成を示す構成図である。搬送車システム101が、図1に示す第1実施形態に係る搬送車システム1と異なる点は、図3に示すように、繁閑判断部37を含む管理コントローラ103を有する点と、走行速度制御部47を含む車体コントローラ(コントローラ)141を有する点とである。ここでは、この管理コントローラ103及び車体コントローラ141について詳細に説明し、第1実施形態の搬送車システム1と共通する点については説明を省略する。
