Abstract
A load port device conveys a container including a gas port to an outer conveyor unit by using a ceiling transportation vehicle. The load port device includes a conveyor, a purging device, and a stocker controller. The conveyor extends to the outer conveyor unit. The purging device is arranged near the outer conveyor unit, and includes a gas supply nozzle to supply purge gas into the container while connected to the gas port, and a first lifting mechanism that moves the gas supply nozzle toward or away from a gas supply port. The stocker controller controls the purging device to supply the purge gas into the container, and to stop supplying the purge gas into the container based on an arrival of the ceiling transportation vehicle to the outer conveyor unit.
