The robot storage system utilized a servo driven gantry robot for fully automatic roll handling. Each roll is stored on a shaft, which is placed in a rack. Multiple racks are positioned in a row, and the robot can transport the rolls from any rack location to either the process location near the cutting table, to the loading or unloading area of the storage, or to a different storage location. This storage facility provides a fast, flexible, and space efficient storage solution when many roll changes are required and changing times between rolls need to be short.
These robot storage systems are always built to customer requirements. Several options are available, such as an additional roll-lifting system to supply rolls to a different floor than where the storage is located, or even a shuttle system to bring rolls from an adjacent storage.
