Device for external sterilisation of plastic parisons
First Claim
1. A system for sterilizing plastic containers, comprising a transport device for transporting the containers during the sterilization along a predefined circular transport path, a clean room within which the containers are transported during the sterilization of the containers, wherein the clean room is delimited by at least one wall with respect to the clean room environment, a first external application device for sterilizing at least a section of an outer wall of the containers, wherein in a region of the transport path in which the first external application device for sterilizing is disposed, the first external application device for sterilizing is surrounded at least in sections by a radiation shielding system having at least one outer radiation shielding device disposed radially outside the circular transport path and one inner radiation shielding device disposed radially inside the circular transport path, by which radiation emitted by the first external application device for sterilizing can be at least partially absorbed, so that with said at least one outer and said at least one inner radiation shielding devices a transport channel is realized which extends between the at least one outer and said at least one inner radiation shielding devices and in which the containers can be transported, wherein the external application device has a source of charge carriers for generation of charge carriers, and a first moving device and a carrier for moving the containers at least intermittently in a longitudinal direction during the sterilization of the containers, a drive device driving the carrier, said drive device having a drive axis which is parallel to a longitudinal direction of the containers, a longitudinal extension of the carrier being parallel to said drive axis of the drive device and parallel to the longitudinal direction of the container, wherein the system has a rotary device for rotating the containers about the longitudinal direction of the containers at least intermittently during the sterilization, wherein the rotary device and the moving device are configured such that a rotation of the containers is enabled during a movement of the containers in the longitudinal direction of the containers, said system further comprising a mechanical coupling device for coupling together the movement of the containers in the longitudinal direction of the containers and the rotary movement of the containers about the longitudinal direction of the containers.

Abstract
A device for sterilizing plastic containers includes a transport device for transporting the containers during the sterilization along a predefined transport path, a clean room within which the containers can be transported during sterilization, wherein the clean room is delimited by at least one wall with respect to the environment, and a first external application device for sterilizing at least a section of the outer wall of the containers. The first external application device has a source of charge carriers for generation of charge carriers, and includes a first moving device which moves the containers at least intermittently in the longitudinal direction during their sterilization. The device also includes a rotary device which rotates the containers about their longitudinal direction at least intermittently during the sterilization, wherein the rotary device and the moving device are preferably configured in such a way that a rotation of the containers is enabled during a movement of the containers in their longitudinal direction.
