RUNNING CONTROL METHOD AND DEVICE OF UNMANNED VEHICLE IN BRANCH OF UNMANNED CONVEYER SYSTEM

摘要

PURPOSE: To eliminate the unnecessary stopping operation and starting operation of an unmanned vehicle which is going to pass a branch,at the near side of the branch. CONSTITUTION: An unmanned vehicle 4A runs on a running rail 3 by receiving the power from a trolley line for power feeding. Converting rails 6a and 6b are provided at the branch 5a of the running rail 3, and a branching device 7 to arrange the converting rails 6a and 6b at the positions corresponding to a specific running rail 3 is provided. A branching control device 1 0 drives and controls the branching device 7, it confirms that the branching device 7 is arranged to a specific position by the detecting signals of limit switches LS1 and LS2, and an advancing permitting signal is transmitted to the unmanned vehicle 4A from a trolley communication device 12. When the CPU of the unmanned vehicle 4A decides that the advancing permitting signal is received from the branching control device 10, the unmanned vehicle 4A continues the running without stopping once at the near side of the branch 5a, and passes the branch 5a.
