SPECIAL SYSTEMS
Automatic storage systems
The automatic storage systems are storage systems in which the deposit and retrieval operations are performed by a computer-guided robot: the stacker crane. The stacker crane is a three-axis machine (i.e. it performs three types of movement: translation in the corridor, upward movement and deposit/retrieval of the load unit) which moves inside the shelves ? in the corridor ? and is guided by rail. The distinguishing feature of the corridor with respect to the corridors of the traditional storage systems is its narrow width, practically equal to the depth of the load unit. The automatic storage systems can be produced with one or more corridors depending on storage requirements. In the case of several corridors, the most common configuration is one stacker crane per corridor but systems are also produced in which one single stacker crane serves several corridors. In this case, steering stacker cranes are used (which, via points systems on the rails, can switch from one corridor to another) or transfer bridges (shuttles that transport the stacker crane from one corridor to another). Systems of this type are used when a large storage capacity is required for low rotation goods. According to requirements, storage can be single, double or multiple depth (see connection below for details), and the stacker crane can transport one or more load units simultaneously. In addition to permitting very high density storage, the automated systems have the advantage of reaching considerable heights that are impossible to reach with traditional storage systems. Building regulations permitting, heights well over thirty metres can be reached without difficulty. Many of these systems areself-supporting, i.e. the shelving supports the side walls and the roof. This offers considerable savings as there is no longer the need for a building to contain the automatic storage system, as the storage system itself constitutes the building. To integrate the storage functions (shelf and stacker crane), the automatic storage system is completed by a set of conveyors which, according to requirements, move the goods from and to the stacker cranes, perform picking operations (both manual and robotised) or connect the automatic storage system with the production lines or with the loading bays of the shipping department.
