摘要： A cigarette inspection device includes four sensors, two for sensing the ends and one for sensing the middle portion of a cigarette to detect loose tobacco and filter presence at the ends, and the presence of a foil band at the middle portion. The fourth sensor provides machine timing information to determine the three conditions of detection. Binary information is then input to a PLC for data reduction and rejection, if the conditions are not present. The program in the PLC allows the end of the cigarette to be scanned multiple times for loose tobacco. Also, foil sensing and filter sensing are done along with the loose tobacco sensing. A shift register is loaded with the resultant detection data, and a reject valve or similar device is operated to remove faulty cigarettes from the product stream.
