The rod-shaped electrode 10 is lifted and separated from the PET bottle 1. When the position sensor provided in the driving means detects the separation of the rod-shaped electrode 10 from the PET bottle 1, the motor 6 is driven to convey the PET bottle 1 to the position C. Then, when it is detected that the plastic bottle 1 has stopped at the position C, the manipulator 13 is driven to grab the plastic bottle 1 from the basket-shaped holder 3 and transfer it to the next step.
