Zusammenfassung: | PROBLEM TO BE SOLVED: To realize a positional deviation correction system of a carrier in an automatic carrying device to permit automatic correction of positional deviation during running when the positional deviation due to individual difference, wear of wheels, slide, etc., of the carrier is generated in the automatic carrying device. SOLUTION: When objects to be carried are carried from optional transfer points A, B, C, D, E, F specified by the carrier 2 moving along a path 1 to other specified transfer points, corrected value of the number of rotations of a running system is calculated based on the transfer point which is passed by the carrier at least, a set value of the number of rotations of the preset running system between the transfer points and measured value of the number of rotations of an actual running system for several times in the past. And the carrier is stopped based on the corrected value of the number of rotations of the running system. |
