Abstract

See full text

A control system performs pre-urging to control a guide wheel driver to urge a guide wheel from a first position toward a second position when the guide wheel in a first width direction in a first guide section is in contact with a first side surface of a guide rail before entering an unguided section. The control system continuously performing the pre-urging allows the guide wheel to pass through the unguided section to move the guide wheel from the first position to the second position in the unguided section, and places the guide wheel in a second width direction in a second guide section into contact with a second side surface of the guide rail.
