Abstract:
1. In a roller gin, containing a ginning roller and a rotary knife rotationally driven by at least one motor, into which seed cotton is fed by a driven seed cotton feeder at variable feed rates, control logic for said driven seed cotton feeder and at least one motor in which said control logic varies the rotational speed of the ginning roller or the ginning roller and the rotary knife in proportion to the rate of feed of said feeder, responsive to one or more sensors operatively positioned in said roller gin to detect one or more conditions in said system critical to the proper functioning of said system, said one or more conditions selected from the conditions including gin roll temperature, gin roll speed, feed rate, seed cotton accumulation at the ginning roller, power required for ginning, and remaining lint on processed cotton seeds, the signals from said sensors employed by said control logic to modulate the rotational speeds of the ginning roller or rotary knife and/or said feed rate of seed cotton to the system, whereby the efficiency of the roller gin is maintained over a defined gin roller speed and feed rate.
