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.
Claims13
An adjustable roll sizer, comprising:
- a first set of rollers mounted to a support structure and arranged in a first parallel array, each roller in the first set defining a longitudinal axis and rotatable thereabout;
- a second set of rollers mounted to the support structure in a second parallel array that is interleaveably alignable with the first parallel array, each roller in the second set defining a longitudinal axis and rotatable thereabout;
- a means for misaligning the second parallel array from the first parallel array;
- and
- at least one motor coupled to at least one roller from the first set of rollers or from the second set of rollers and configured to cause the at least one roller to rotate about the longitudinal axis of the at least one roller synchronously with rotation of the motor.
