Elscint manufactures a Sorting & Grading Unit for small Shims. The Elscint Sorting and Grading Unit is designed to feed, sort and grade components like shims which require to be graded according to their thickness. This Unit operates at a speed in excess of 150 pieces per minute, depending on the size of the components. The system utilizes an Elscint Vibratory Bowl Feeder of suitable mode amongst the 6 Models of Elscint Vibratory Bowl Feeders. The Bowl Feeder feeds the parts to a set of powered gauge rolls. These are powered by an Elscint Geared Motor of suitable rating. The inclination of the rolls, plus adjustable roll spacing from one end to the other enables parts to move / travel easily and rapidly into the desired position, while moving them to the discharge point. Undersized parts are first separated, followed by those within tolerance. Oversize and damaged or oversize parts continue to the end of the rolls and are discharged into a separate container. An important feature is that the rolls being counter-rotating does not bind or grip the parts and are extremely sensitive to fine tolerances. The basic unit works on a fixed speed, however, optionally Elscint can also offer Sensor and a variable speed AC or DC motor fitted with an Elscint Reduction Unit. This unit offers high flexibility for the user and can also be used for sorting and grading of Balls, Taper Rollers, Pins and similar components.
