ABSTRACT:
A moving bin sorter has trays which are sequentially shifted upwardly and downwardly relative to a sheet inlet location by a rotary cam driven by an electric motor which drives the cams in opposite directions. The minimum force applied by the motor and lowest motor speed depends upon the load represented by the trays, the weight of the sheets of paper in the trays and the load balancing effect of a spring employed to assist in the lifting of the trays upwardly to engage the cam. The motor power is adjusted and controlled to reduce the applied motor force and speed dependent upon the load which must be overcome in either the upward or downward movement of the trays, for noise and wear reduction.
