Air cargo transport system
First Claim
1. An air cargo transport system having guide lines which connect an air cargo holding area in an airport terminal building with an aircraft parking area on a tarmac, and a plurality of auto-running tow vehicles for conveying air cargo which can automatically run along the guide lines, comprising:
- a plurality of branch marks at each branch guiding said auto-running tow vehicles to the aircraft parking area; and
a plurality of stop marks which cause said auto-running tow vehicle to stop at a desired aircraft parking area by reading said stop mark provided along said guide line in order to automatically tow the air cargo from the air cargo holding area in the airport terminal building to the aircraft parking area,wherein;
the plurality of branch marks includes bar code marks, light emitting elements and embedded oscillators, each of said branch marks imparting a specific meaning to guide the plurality of auto-running tow vehicles to turn right or left based upon memorized route instructions,each of said plurality of auto-running tow vehicles is configured to have and is controlled by a rule which determines which of said plurality of auto-running tow vehicles should have priority to proceed along said guide lines in order to avoid accidents and collisions between the auto-running tow vehicles when said plurality of auto-running tow vehicles merge in the same direction at a branching point, andsaid establishing priority is based on which side of sensors provided on both sides of said each of plurality of auto-running tow vehicles detects said branch mark.

Abstract
The cargo transport system according to this invention employs a tow vehicle that can automatically follow and run upon guide lines. The tow vehicle can tow cargo laden equipment such as container dollies to thereby automatically transport the air cargo. The air cargo is conveyed by an underground air cargo conveyor mechanism which has the conveyor line including the guide line installed underground to link the air cargo holding area in the airport terminal building and the aircraft parking area. Further, the system connects the loading/unloading cargo door of the aircraft and the underground loading/unloading position for the underground air cargo conveyor mechanism by an air cargo elevator.
