Automatic trolley clamp lock

摘要

The present invention provides systems and methods that reduce the number of mis-routed trolleys in an AGV system. The invention provides a solenoid driven automatic coupling for coupling a trolley to an AGV. When an AGV arrives at a particular preprogrammed destination, as determined for example by track patches read by the AGV, the AGV system switches the solenoid power causing the automatic coupling to free the trolley to disengage from the AGV. The AGV may then pull away from the trolley, leaving the trolley at its programmed destination. The system substantially eliminates the risk of a trolley not being uncoupled prior to the AGV's departing from the trolley's intended destination.
