Abstract: |
An automated material handling system for combining over-head conveyer with a material control system is disclosed. First and second virtual stocker codes are respectively assigned to first and second virtual stocker of an over-head conveyer (OHC) using a material control system. A front opening unified pod (FOUP) is moved to and loaded in the first virtual stocker using a transport system controller. The FOUP is loaded in a track of the OHC and assigned a virtual vehicle code. The FOUP is moved, along the track, to the second virtual stocker and loaded in the second virtual stocker, while the virtual vehicle code is being removed, and is removed therefrom using the transport system controller. |
