Target Vent Tube Detection System detects the presence of a loose or broken vent tube that has drop in to a bottle during the filling process.
Loose vent tubes are very difficult for visual inspectors to detect in filled bottles , particularly in the darker amber or green bottle or those having labels that obscure the vent tube image.
Although occurring in frequently, the presence of a vent tube in a beverage bottle is very delicate consumer problem that every bottler must address. Reliable detection of this type of defect is an absolute requirement.
Target vent tube detection system is mounted downstream of the filler. It is connected to the bottle production line so that detector presence of a vent tube will immediately stop the production line and set the interlock controls ( Potential Free Contact Provided - PFC ). The line operator must remove the defective bottle and reset the system before the production chain will run again.
Since the electro-magnetic detection field of the TVTDS -150 spans several bottle diameters, all those bottles should be removed from the production line to ensure the on containing the vent tube is no longer present. The line operator may then carefully inspect and remove the bottle containing the vent tube.
Utilization of an automatic rejection system is not recommended since a loose or broken vent tube occurs rarely that the additional cost is not justifiable. The filler or bottle line should be stopped when a vent tube is lost since all bottles from that valve will not be properly filled.
The mechanical installation of the TVTDS-150 is a very simple and in most cases can be carried out by the plant technicians.
