Improved Sample Flow for Cotton Classing Offices

Matt Matthews, Darryl W. Earnest, James A. Randle


The Cotton Division's Classing Offices are responsible for determining High Volume Instrument fiber properties and assigning manual color and trash grades to every bale of cotton grown in the United States. The volume of cotton samples required to pass through the classing offices during the short harvest season creates a material handling problem. Several systems were investigated for solutions to the problem. The "zero-pressure" powered roller conveyor was chosen for our application because of its ability to continuously accumulate samples and eliminate back-pressure between trays of cotton. The "zero-pressure" system was implemented in the Rayville, LA Classing Office for the 1993 season and produced a considerable cost savings as well as an increase in overall office efficiency.
