Abstract

PURPOSE:To check an automatic start by discriminating between the automatic start and the continuation of a stopping state when a trailing dolly arrives while a leading dolly is still, only by giving a difference in length between break parts. CONSTITUTION:The length of a break part 3 at a work place A is greater than that of a break part 3' at a normal stop point before a branch point. When the short break part 3' is detected by the 1st detector 4, the detector 4 closes and operates a stop commanding device to stop a dolly 2, but the detector 4 passes the break part 3' through the movement of the dolly 2 from the detection point in the time to the stop point, so that it opens again. Consequently, when the 2nd detector 6 detects a trailing dolly, a start commanding device operates for an automatic start. On the other hand, when the detector 4 detects the long break part 3, the dolly 2 stops as well, but the detector 4 stops on the break part 3, so the detector 4 holds itself closing. Therefore, even when the detector 6 detects the trailing dolly, the dolly is in a still state.
