Abstract
An upstream side wheel includes grippers B which do not perform opening and closing operations for themselves, and a downstream side wheel includes grippers A each having an opening and closing mechanism, and in a delivery position in which both the wheels are adjacent to each other, a plastic bottle 1 is delivered from the gripper B to the gripper A. Here, if the upstream side wheel or the downstream side wheel abnormally stops, the grippers A are switched from a use state to a retreat state. Thereby, interference between plastic bottles gripped by the upstream side grippers and the grippers of the downstream side wheel is avoided. Even if one of the wheels abnormally stops, the other wheel can be continuously operated without increasing the equipment in size.
