Automatic material handling system and stocker therefor

摘要

An automatic material handing system (AMHS). The AMHS comprises a rail, an overhead shuttle (OHS) and a stocker. The OHS moves on the rail. An in/out port (I/O port) is disposed in the stocker. The rail passes through the stocker and enters the I/O port. When the OHS is in the I/O port, a transport device places goods directly into the OHS.
