Abstract: Inspection systems and methods for their use comprise: a movable carrier with spaced receptacles, each sized to accept a sample; a first pin positioned proximate to the movable carrier and connected to a first movable member capable of reciprocally moving the first pin alternately into and out of contact with a first end of a sample disposed in one of the spaced receptacles; a second pin positioned proximate to the movable carrier and connected to a second movable member capable of reciprocally moving the second pin alternately into and out of contact with a second end of the sample disposed in the one of the spaced receptacles; a measurement sensor capable of determining a value associated with the sample disposed in the one of the spaced receptacles; and an evaluation device in communication with the measurement sensor for receiving the value, the evaluation device providing a comparison between the value and a predetermined value.

Abstract: Inspection systems and methods for their use are described, wherein the systems comprise: a movable carrier having a plurality of spaced receptacles, each spaced receptacle sized to accept a sample; a first pin positioned proximate to the movable carrier and connected to a first movable member capable of reciprocally moving the first pin alternately into and out of contact with a first end of a sample disposed in one of the spaced receptacles; a second pin positioned proximate to the movable carrier and connected to a second movable member capable of reciprocally moving the second pin alternately into and out of contact with a second end of the sample disposed in the one of the spaced receptacles; a measurement sensor capable of determining a value associated with the sample disposed in the one of the spaced receptacles; and an evaluation device in communication with the measurement sensor for receiving the value, the evaluation device providing a comparison between the value and a predetermined value.

Abstract: A method and apparatus for compacting particles or granules in discrete cavities spaced along an article or articles such as a cigarette filter rod moved underneath the compacting system. The compacting system can be provided with spaced lugs or other protrusions that selectively compact particles within cavities, or a smooth outer periphery that results in progressive compaction of the entire article being moved underneath the compaction system. The article having cavities with particles that need to be compacted can be supported on a support rail with side support rails that maintain the shape of the article during the compaction process.

Abstract: A cigarette filter rod system comprises a plug combiner machine having a knife located downstream from a sensor. The knife generates a trigger signal which prompts an Inspection Unit to locate a previously stored frame of sensor data corresponding the rod which was cut by the knife. The Inspection Unit applies thresholds to the frame of sensor data to determine the location of filter segment boundaries, and then determines whether air rings are present in the data. The Inspection Unit then compares measurements made on the frame of sensor data with a pre-stored recipe indicating expected values for the frame. Statistical data is sent to a Human-Machine Interface Unit for analysis and display. The system performs filter rod rejection and cut registration based on the analysis performed by the Inspection Unit and the Human-Machine Interface.
