Title:
DEVICE FOR CORRECTING TRAVELLING DISTANCE OF UNMANNED CARRIER CAR AT THE TIME OF ABRASION OF TIRE
Document Type and Number:
Japanese Patent JPS60239811
Kind Code:
A
Abstract:
PURPOSE:To omit the changing work of a set value of a travelling distance and to prevent the generation of an accident due to the unexecution of the work by calculating a correcting distance signal and comparing said signal with a distance signal up to a destination to execute processing required up to the destination. CONSTITUTION:When an unmanned carrier car is started, the number n3 of pulses obtained during travelling before correction is detected by a pulse detecting sensor 9. If marks M1, M2 are detected by a mark detecting sensor 15, a CPU11 calculates the number n4 of sectional pulses obtained when the carrier car travels a correcting section D formed by both the marks M1, M2 and stores the calculated value in a RAM12. Then, the CPU 11 reads out the mumbers n2, n1 of sectional pulses obtained in a section D and between stations S1 and S2 by an unabrased tire 3 from the RAM12, calculates the number n5=n3Xn2X n4 of pulses obtained during the travelling after correction and compares n5 with n1. When both the values concide with each other, the CPU11 stops a driving motor 6 and executes the processing at the destination, and in case of inconsistency, travels the carrier car until coincidence.
