To prevent electrical charging inside a resin material as well as a surface of a resin vessel at a time of sterilizing the resin vessel by being irradiated with electron beam, a bottle support unit is mounted to a lower end portion of a cylindrical rotating shaft rotatably supported by a rotating wheel. The bottle support unit includes a pair of griper members by which a mouth portion of a bottle is gripped. A ground electrode is disposed to be capable of being inserted into the interior of the resin vessel through a mouth portion thereof, and the interior of the resin vessel is irradiated with the electron beam in a state of the ground electrode being inserted into the resin vessel.

Apparatus and method for sterilizing vessel with electron beam

It is aimed to prevent electrical charging inside a resin material as well as a surface of a resin vessel at a time of sterilizing the resin vessel by being irradiated with electron beam. A bottle support unit is mounted to a lower end portion of a cylindrical rotating shaft rotatably supported by a rotating wheel. The bottle support unit includes a pair of griper members by which a mouth portion of a bottle is gripped. The bottle rotated and conveyed in a state supported by the bottle support unit is irradiated with the electron beam from an electron beam irradiator to thereby sterilize the bottle. A ground electrode is disposed to be capable of being inserted into the interior of the resin vessel through a mouth portion thereof, and the interior of the resin vessel is irradiated with the electron beam in a state of the ground electrode being inserted into the resin vessel. Since extra electrons or ions generated by the irradiation to the resin vessel with the electron beam flow outside, the charge amount of the resin vessel is alleviated.

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 bottleis 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.
