Abstract
An adjustable roll sizer for sorting objects of different sizes includes a first set of rollers mounted to a support structure and arranged in a first parallel array. A second set of rollers is mounted to the support structure in a second parallel array that is interleaveably alignable with the first parallel array. Means for automatic control are provided for misaligning the second parallel array from the first parallel array to vary gap width between adjacent rollers. Each roller in the second parallel array may also be tapered to vary gap width as a function of roller length. Rollers may include helical ridges for urging objects along the gaps.
Claims23
An adjustable roll sizer, comprising:
- a first set of rollers mounted to a support structure and arranged in a first parallel array;
- a second set of rollers mounted to the support structure in a second parallel array that is interleaveably alignable with the first parallel array;
- and
- a means for misaligning the second parallel array from the first parallel array.
An adjustable roll sizer, comprising:
- at least one fixed roller mounted to a support structure, the fixed roller rotatable about a fixed longitudinal axis;
- at least one pivoting roller having a pivot end pivotally mounted to the support structure and an actuator end opposite the pivot end;
- and
- an actuator coupled to the actuator end and configured to cause the at least one pivoting roller to pivot about the pivot end in a plane parallel to the fixed longitudinal axis.
