Apparatus and method for treating containers with ionised air
Apparatus for treating plastic preforms, having a transport device which transports the plastic preforms along a predetermined transport path, having a first application device which loads the plastic preforms with a first flowable medium through their mouth during their transport along a first transport path section, wherein the apparatus has a second application device which acts upon the plastic preforms with a second flowable medium during their transport along a second transport path section through their mouth.
1. An apparatus for treating plastic preforms, said apparatus having a transport device which has a circulating carrier configured to transport the plastic preforms along a predetermined transport path, a first application device configured to act upon the plastic preforms with a first flowable medium through a mouth of the plastic preforms during transport of the plastic preforms along a first section of the transport path, and a second application device configured to act upon the plastic preforms with a second flowable medium during transport of the plastic preforms along a second section of the transport path through the mouth of the plastic preforms, wherein at least one of said first or said second application devices has an ionising device for ionising air, so that the first or second flowable medium is ionised air, wherein said first and said second application devices comprise an application element configured to introduce the first flowable medium and the second flowable medium into the plastic preforms, and wherein said first application device and said second application device are configured to use the application element to act upon the plastic preforms with the first flowable medium and the second flowable medium,
further comprising a suction device configured for sucking off air or a substance containing contaminants out of the plastic preforms, wherein the application of the first flowable medium and the suction with regard to a specific one of the plastic preforms take place at the same time, and
further comprising a switching device configured to switch over from acting upon the plastic preforms with the first flowable medium to acting upon the plastic preforms with the second flowable medium.
2. The apparatus according to claim 1 , wherein said first application device has a compressed air unit configured to provide as the first flowable medium a compressed air to the first application device and/or said second application device has a compressed air unit configured to provide as the second flowable medium a compressed air to the second application device.
3. The apparatus according to claim 2 , wherein said first application device comprises a providing unit configured to provide the first flowable medium as a sterilization medium to the first application device and/or said second application device comprises a providing unit configured to provide the second flowable medium as a sterilization medium to the second application device.
4. The apparatus according to claim 2 , wherein the circulating carrier is rotatable with respect to an axis of rotation and on which a plurality of holding devices for holding the plastic preforms is arranged, wherein each of the holding devices has one application element for acting upon the plastic preforms with the first and second flowable medium.
5. The apparatus according to claim 1 , wherein said first application device comprises a providing unit configured to provide the first flowable medium as a sterilization medium to the first application device and/or said second application device comprises a providing unit configured to provide the second flowable medium as a sterilization medium to the second application device.
6. The apparatus according to claim 1 , wherein the circulating carrier is rotatable with respect to an axis of rotation and on which a plurality of holding devices for holding the plastic preforms is arranged, wherein each of the holding devices has one application element for acting upon the plastic preforms with the first and second flowable medium.
7. An arrangement for treating plastic preforms with an apparatus according to claim 1 , the arrangement comprising a device configured for sterilising the plastic preforms or plastic containers formed therefrom arranged downstream of the apparatus in the transport direction of the plastic preforms.
8. A method for treating plastic preforms with an apparatus according to claim 1 , wherein the transport device transports the plastic preforms along the predetermined transport path with the first application device acting upon the plastic preforms during their transport along the first transport path section through a mouth of the plastic preforms with the first flowable medium, and with the second application device acting upon the plastic preforms with the second flowable medium during their transport along the second transport path section through the mouth of the plastic preforms.
