Consolidated engagement-disengagement method and an automatic transport system for automatic guided vehicles in an automatic transport system using an automatic guided vehicle towing the transport carriage and the transport carriage
PROBLEM TO BE SOLVED: To provide a connection engagement/connection disengagement method for an automatic carrier and a transportation dolly, the method preventing damage to a power transmission part caused by excessive force applied to a connection device of the automatic carrier traveling with the transportation dolly in tow, the excessive force due to a drastic change in a traveling surface.SOLUTION: During transport-traveling of a transportation dolly towed by an automatic carrier, a given magnitude of rotary excitation force is applied by rotary excitation means to a towing arm 40 in a normal connection engagement direction toward an engagement member, and, if force exceeding a given magnitude is applied to the towing arm 40 of a connection device 30 due to a change in a traveling surface of the automatic carrier during the transport-traveling, an excessive magnitude of load transmitted to an arm drive motor 45 or its power transmission means is avoided.
