Abstract

A container treatment plant having an oven, a blow molder located downstream of the oven and used for processing a plurality of container blanks, such as preforms, and a conveying unit configured for conveying a plurality of carriers, each carrier being provided for accommodating at least one container blank, and the conveying unit and the carrier being adapted to one another such that each carrier is individually movable through the oven.

First claim

The invention claimed is:

1. A container treatment plant, comprising an oven, a blow molder located downstream of the oven and used for processing a plurality of container blanks, a conveying unit configured for conveying a plurality of carriers, each carrier being provided for accommodating at least one container blank, the conveying unit and the carrier adapted to cooperate with one another such that each carrier is individually movable through the container treatment plant by means of said conveying unit and at least one of the carriers is configured for movement in a magnetic force dependent manner, wherein each carrier comprises at least one rotary holder configured for rotatingly accommodating a container blank, wherein the oven comprises at least one infrared radiator.

2. The container treatment plant according to claim 1 , the conveying unit and the carrier being further adapted to cooperate with one another such that each carrier can be used for individually moving a container blank through the oven by means of said conveying unit.

3. The container treatment plant according to claim 1 , the same conveying unit fully extending through the oven and further extending through the blow molder, so that the same carrier can be moved through the oven as well as through the blow molder, with the container blank remaining inserted therein.

4. The container treatment plant according to claim 1 , and at least one of the carriers includes a servomotor used for the purpose of driving.

5. The container treatment plant according to claim 1 , and the oven has a flexible pitch.

6. The container treatment plant according to claim 1 , and the at least one carrier includes a carriage section, which rests on the conveying path, and at least one rotary holder projects from the carriage section.

7. The container treatment plant according to claim 6 , and the rotary holder includes one or a plurality of spindles, each comprising at least one mandrel to which the container blank can be applied.

8. The container treatment plant according to claim 7 , and at least one spindle is coupled to the carriage section via a quick fastener.

9. The container treatment plant according to claim 7 , and at least one spindle comprises a gripping section for gripping round the container blank.

10. The container treatment plant according to claim 7 , and at least one spindle is provided with external teeth or with a force transmitting area.

11. The container treatment plant according to claim 7 , each container blank of the plurality of container blanks accomplishes a predetermined heating profile.

12. The container treatment plant according to claim 1 , and the container blanks comprise preforms.

13. The container treatment plant according to claim 1 , and the movement is in interaction with a conveying path of the conveying unit, on which the at least one of the carriers slidingly rests.

14. The container treatment plant according to claim 10 , and the at least one spindle provided with external teeth comprises a gear.

15. The container treatment plant according to claim 10 , and the at least one spindle provided with a force transmitting area comprises a friction wheel.

16. The container treatment plant according to claim 11 , and the predetermined heating profile comprises an individual heating profile.
