Inspection system for a smoking article having an object inserted therein, and associated method

Abstract

A system and associated method is provided for inspecting filter rods used to form cigarette filter elements, wherein each filter rod defines a longitudinal axis extending between opposed ends, with each end extending substantially perpendicularly to the longitudinal axis, and includes a filter material having an axially-extending strand disposed therein. A filter rod support device is adapted to receive at least one filter rod such that one end thereof is exposed. An analysis unit is disposed with respect to the filter rod support device so as to interact with the one end of the at least one filter rod to determine a status of the at least one filter rod and to provide a corresponding signal in response thereto.

         17 . A method for inspecting filter rods used to form cigarette filter elements, each filter rod defining a longitudinal axis extending between opposed ends, each end extending substantially perpendicularly to the longitudinal axis, and including a filter material having an axially-extending strand disposed therein, the method comprising:
 receiving at least one filter rod in a filter rod support device such that one end of the at least one filter rod is exposed;   analyzing the one end of the at least one filter rod using an analysis unit; determining a status of the at least one filter rod from the analysis of the one end; and   providing a signal in response to and corresponding to the determined status.   
     
     
         18 . A method according to  claim 17  wherein receiving the at least one filter rod further comprises receiving the at least one filter rod such that both ends are exposed, and the analyzing step further comprises analyzing at least one of the ends of the at least one filter rod to determine the status of the at least one filter rod. 
     
     
         19 . A method according to  claim 17  wherein the analyzing step further comprises analyzing an image of the one end of the at least one filter rod using an image analysis unit. 
     
     
         20 . A method according to  claim 19  further comprising capturing the image of the at least one filter rod using an image acquisition device. 
     
     
         21 . A method according to  claim 19  further comprising displaying, in response to the signal, an indicia corresponding to the determined status on a display unit in communication with the analysis unit. 
     
     
         22 . A method according to  claim 17  wherein determining a status of the at least one filter rod further comprises determining at least one of a strand presence within the filter rod, a strand absence from the filter rod, an acceptable strand presence in the filter rod, and an unacceptable strand presence in the filter rod. 
     
     
         23 . A method according to  claim 22  wherein determining a status of the at least one filter rod further comprises determining one of an acceptable strand presence in the filter rod and an unacceptable strand presence in the filter rod with respect to a characteristic selected from the group consisting of strand disposition within the filter material, strand alignment within the filter material, strand configuration, strand type, strand color, strand size, strand condition, and combinations thereof. 
     
     
         24 . A system according to  claim 22  further comprising removing, in response to the signal, the at least one filter rod from the filter rod support device using a filter rod removal device operably engaged with the analysis unit and the filter rod support device, and discarding the at least one filter rod, when the status corresponds to one of the strand absence from the filter rod and the unacceptable strand presence in the filter rod.
