ABSTRACT:
A flexible automatic test facility for measuring physical parameters of smoking articles and components of smoking articles, e.g., filter portions. The test facility includes a microprocessor based controller device, apparatus for severing the filter portion from the article, a plurality of instruments for performing the desired measurements and a computer-controlled robot for gripping and maneuvering one cigarette at a time to one or more of the instruments or severing apparatus to measure one or more physical characteristics of each article or its components in accordance with software instructions. A hopper feeder device containing a plurality of sample sets in separate bins in an indexing mechanism may be provided for extended unattended operation. Each sample set is provided with a code and a database including the nominal physical characteristics of the samples in the set and the test sequence for the cigarettes in the sample set. The test sequence and parameters for each article in each set are obtained from the database, and the controller instructs the robot to grip a fed cigarette and to advance that cigarette to one or more of the instruments for performing measurements or processing station for severing filter in accordance with the predetermined sequence of measurements. At the conclusion of the samples in a given sample set, the next sample set is loaded, identified, and the process continues in accordance with the predetermined sequence for that sample set.
