Abstract
In an inspection or processing machine machine for returned PET multitrip bottles the bottles are acted upon by a laser beam, in order to examine the bottles and/or read a code on the bottle and/or write a code on the bottles. The bottles run in the machine on a carousel. The laser beam is directed through a central hollow shaft of the carousel via mirrors onto the bottle. The moving bottles can thereby be acted upon in a simple manner.
Claims7
Process for acting upon containers which are moving along a conveying path through a conveying means with at least one laser beam for inspection and/or processing of the containers, characterized by conveying the containers along the conveying path by means of a carousel having a hollow central shaft about which the containers move, directing the laser beam through the hollow central shaft and guiding the laser beam via a mirror arrangement which is mounted in relation to the hollow central shaft to scan the beam over at least one section of the conveying path synchronously with each container to act thereupon.
A machine for processing bottles with at least one laser beam comprising:
- conveying means including a carousel having a hollow central shaft for moving the bottles along a conveying path;
- a laser light source producing a laser beam which is directed from the source into the hollow central shaft of the carousel and then onto the bottles moved by the conveying means;
- and
- mirror means mounted in relation to the hollow central shaft of the carousel to guide the laser beam from the shaft over at least one section of the conveying path synchronously with each container to cause the beam to act upon a bottle moving along the conveying path.
