<p><P>PROBLEM TO BE SOLVED: To correctly stop a conveying vehicle with respect to a station. <P>SOLUTION: When a cargo bed 8 is not present in a center part of a station 4, one pusher is firstly abutted on the station 4, and the cargo bed slides in the right-to-left direction by its reaction force. When a pair of pushers 20, 20 are abutted on the station 4, sprockets 14, 15 are not rotated, which is detected by a rotary encoder or the like. Next, a motor is slightly driven in the reverse direction to release the abutting of the pusher 20 on the station 4, and the motor is stopped and locked. In this condition, the cargo bed 8 is positioned at the center part of the station 4, and when the cargo bed is elevated by using a pantograph, a roll can be positioned in a centered state with respect to the cargo bed 8. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
