MOBILE CARRIAGE SYSTEM WITH NO RAILS FOR GUIDANCE SYSTEM

摘要

A mobile storage system that includes a guidance system controlling the movement of each of a plurality of movable carriages along a support surface. The mobile storage system includes a guidance system having a magnetic strip positioned on the support surface. One or more magnetic sensors are positioned on each of the mobile carriages and generally aligned with the magnetic strip positioned on the floor. The magnetic sensors detect the magnetic strip and a control unit controls the operation of a pair of drive motors to move the carriages along the mobile strip while maintaining proper alignment. The guidance system thus eliminates the need for any floor mounted rails to guide the movement of the individual mobile carriages along the support surface.
