PURPOSE:To carry a self-travelling carrier track efficiently by arranging branching/combining devices on two positions with a proper interval in each subline and setting up a waiting station part between the two positions to form the waiting part for an empty self-travelling carrier track on the leading end side. CONSTITUTION:The branching/combining device 8b on the side near working station out of the branching/combining devices 8a, 8b arranged on both the sides of the waiting station part 10 consists of two pairs of rails 13, 14 and are constituted so as to be reciprocated in the direction rectangular to a main line 6 and a subline 7. To move the selftravelling carrier track completing its working in the station part 9 to the rail 13, the track is positioned on the rail 13, the branching/combining device 8b in the arrow A direction, and when the rail 13 is aligned to the line 6, the track is shifted to the line 6. |
