<p>A rotational position determining method and a rotational position determining system which can improve the efficiency and reliability of the determination of a rotational position. A rotational position determining method and a rotational position determining system use two rotational position determining devices (10(a), 10(b)) which are arranged in the conveyance direction of a conveyor (12). The method and the system are configured so that one rotational position determining device (10(a)), which is disposed on the rear side in the conveyance direction, rotates a container (14(a)) about a rotation center axis (C1) and stops the rotation of the container (14(a)) when a sensor (21(a)) detects a mark on the surface of the container (14(a)), and so that the other rotational position determining device (10(b)), which is disposed on the front side of the conveyance direction, rotates a predetermined angle a container (14(b)), the rotation of which was stopped by said rotational position determining device (10 (a)) when a mark was detected, and after that, stops the rotation of the container (14(b)).</p> |
