Abstract

See full text

A movable rack system able to carry out a widthwise shift control of a movable rack without using a sheet rail member to be detected. The system is so configured, that magnets are placed at stop positions of the movable rack on the floor surface as members to be detected, while the movable rack is equipped with magnetic sensors to detect the magnets. When the movable rack stops traveling, the magnetic sensors detect the magnets and compares the detected magnetic intensity to the magnetic intensity detected at the previous stop. If the change exceeds a pre-determined value, namely the widthwise shift exceeding a pre-determined value is detected, a travel route of the movable rack to eliminate the widthwise shift is determined. In the next travel of the movable rack the rotation speeds of the respective driving motors are controlled so that the movable rack follows the travel route.
