Title:
SERVICE CAR
Document Type and Number:
Japanese Patent JPS5699511
Kind Code:
A
Abstract:
PURPOSE:To make the service car run along the prescribed target line easily and also exactly, by installing a flexible pantagraph-shaped sensor to the service car. CONSTITUTION:As for the flexible pantagraph-shaped sensor 3 with is constituted of plural parallelograms A by connecting plural links 6, its one end is installed to the car body 2 so that it can be rocked freely. Also, the other end is installed to the guide 5 through the working part 4 so that follow-up slide can be made. And, the detection mechanism 9 detects overall length of the sensor from the angle of the parallelogram A, and the detection mechanism 14 detects the tilted angle to the horizontal surface of the sensor 3. The calculation mechanism 16 calculates the horizontal distance of the car body 2 to the guide, by said detection result. This calculated value is compared with the set point from the setting device 17 by the comparator 18, and by controlling the run of the car body 2, it can be executed easily and also exactly to run along the guide 5.
