COLLISION PREVENTING DEVICE FOR UNMANNED GUIDANCE CAR

摘要

PROBLEM TO BE SOLVED: To obtain the collision preventing device for the unmanned guidance car which has a simple structure, never misreceives signals from other travel courses, and can stop the car at a proper braking distance even on a curved track. SOLUTION: The collision preventing device detects the electromagnetic wave sent by a transmitting antenna 32 provided on a precedent unmanned guidance car traveling in a travel course by a receiving antenna 33 provided on another unmanned guidance car traveling behind the former unmanned guidance car and limits the travel of the latter unmanned guidance car according to the detection signal. The reception direction of the receiving antenna 33 is controlled almost to the steering direction of the latter unmanned guidance car.
