<p>A rotational position determination device capable of accurately determining a rotational position using a compact configuration. A rotational position determination device (10) is configured so that a container (14), which is a workpiece conveyed by a conveyor (12, 25, 26), is oriented to a specific direction by being rotated about the rotation center axis (C1) of the container, the rotation center axis (C1) being parallel to the conveyance direction (X-axis direction). The rotational position determination device (10) comprises a rotation means (18) for rotating the container (14) about the rotation center axis (C1) thereof by rotating a drive roller (16), which is made to be in contact with the container (14) being conveyed, about the rotation center axis (C2) of the drive roller; a stop means (20) which, when the container (14) is oriented to the specific direction, stops the container (14) which is being rotated; and a following drive means which, by means of the electrical control of a servomotor, causes the drive roller (16), which is made to be in contact with the container (14), to follow the conveyor (12, 25, 26).</p> |
