GUIDANCE SYSTEM FOR CARRYING CAR

PURPOSE:To simplify the work for determining a carrying path by operating position information of a guide sensor by a land mark obtained by a guide sensor and a detecting signal of a guide tape, and controlling a driving device. CONSTITUTION:A positioning device 7 for controlling driving devices 6L, 6R is provided with a counter 10 for receiving a pulse signal of rotary position detectors 5L, 5R for detecting a moving distance of a carrying car 1, and a comparator 11 for receiving a detecting signal sent from guide sensors 4L, 4R and bringing it waveform shaping. Also, this device is provided with a latch 12 for counting the number of pulses at the time of passing through a land mark from signals from the comparator 11 and from the counter 10. Moreover, this device is provided with a CPU 13 for operating passing positions SL,R (xs, ys) of a guide sensor of a shorter land mark passing distance from pulse signals from the counter 10 and the latch 12, and a motor controller 14 for controlling a motor of a driving device 6 by an arithmetic value of the CPU 13. In such a way, by operating a distance between a carrying car and a guide tape and giving a command to the motor controller, the carrying car can be moved simply to a positioning point by the driving device 6.
