<p>PROBLEM TO BE SOLVED: To provide an unmanned vehicle system for wagon truck conveyance for which severe positioning is not required when arranging a wagon truck at a prescribed position. SOLUTION: When an unmanned vehicle 10 detects a magnetic mark 4, traveling is started along a guide line 23 provided on the bottom face of wagon truck 20 by a guide sensor 16. When a mark sensor 18 detects a magnetic mark 24 later, traveling is stopped, a hook pin 19 is protruded and engaged with a hook hole 25 of wagon truck 20, and the wagon truck 20 is drawn to the destination of delivery. At such a time, since the width of guide line 3' inside a frame line 2 is made wider by laying guide lines 3a and 3b on both sides, even when the wagon truck 20 is obliquely arranged inside the frame line 2, the wagon truck 20 can be drawn to the destination of delivery without losing the guide line 3.</p> |
