Title:
STEERING APPARATUS FOR UNMANNED CARRIER
Document Type and Number:
Japanese Patent JPH04343108
Kind Code:
A
Abstract:
PURPOSE:To always permit an unmanned carrier to run on the approximately center of a guiding tape when it takes a curve and to attain the stabilization of curve running and the speed-up of curve running speed. CONSTITUTION:Means 2, 4, 13, 14, 15, 17, and 18 applying prescribed bias voltage having a polarity corresponding to a curve direction to a steering signal based on the output of a guide sensor 1 detecting the guiding tape at the time of curve running, are provided. These means consist of a mark detector 2, a curve direction setting switch 4, switch elements 13 and 14, retention circuit 15 and AND circuits 17 and 18. Thus, at the time of curve running, the unmanned carrier can be made to run on the approximate center of the guiding tape by superimposing the bias voltage to the steering signal.
