Title:
REFUELING MACHINE
Document Type and Number:
Japanese Patent JP3137508
Kind Code:
B2
Abstract:
PURPOSE: To calculate the error of position signal obtained through calculational processing and automatically drive and control refueling machine accurately by comparing the position signal concerning the detected reference position and the operated bridge position signal.
CONSTITUTION: The rotation of a bridge pinion 18a and a trolley pinion 18b placed on a bridge 15 and a trolley 16 of a refueling machine 19 is converted to an electric signal with a bridge synchronous oscillator 1a and a trolley synchronous oscillator 1b and processed with a calculator to obtain each present position. To the bridge 15 and the trolley 16, limit switches 6a and 6b are provided and strikers 14a and 14b are provided beside a running rail 11 and a sliding rail 12 where the bridge 15 and the trolley 16 move. When the switches 6a, 6b reach a reference point, this is operated with the strikers 14a and 14b. Then, by comparing the reference position signal detected with the switches 6a and 65 and the position signal detected with the oscillators 1a and 1b and operated with a computer, error is calculated.
