Abstract

The present disclosure is directed to a stocker utilizing one or more storage carriers to optimize the utilization of a storage compartment within the stocker. The stocker includes one or more storage towers each including one or more shelves that may be moved from a closed position to an opened position by being pulled outward by a hook of a forking structure. This forking structure is configured to lift up a corresponding storage carrier off the shelf to be transported to a storage carrier load port to position one or more workpieces or toolpieces within the storage carrier, which is then transported back to the corresponding shelf for storage. The utilization of the forking structure along with the pull out shelves allows for a large number of storage carriers to be stored within the storage compartment of the stocker.
