Abstract: A workpiece stocker houses a workpiece setting member such that the workpiece setting member is able to be pulled out from a housed position to a vehicle working position side and an opposite vehicle working position side. An automated transport system identifies a target workpiece stocker and a target workpiece setting member for an operation to be performed by a robot mounted on an automated guided vehicle and drives a pullout restriction mechanism unit to prevent the workpiece setting member from being pulled out to the opposite vehicle working position side or being pulled out to the vehicle working position side before the automated guided vehicle arrives at a working position and the robot pulls out the workpiece setting member to the vehicle working position side after the identification.
