Elscint Automation is introducing a Sorting and Grading Unit for small shims and similar components. The Elscint Sorting and Grading Unit is designed to feed, sort and grade parts by thickness, operating at a speed in excess of 150 parts per minute, depending on the size of the components.
The system utilises an Elscint vibratory bowl feeder that presents the parts to a set of gauge rolls, which are powered by an Elscint geared motor. The inclination of the rolls, plus adjustable roll spacing from one end to the other, enables parts to move easily and rapidly into the desired orientation, while also being conveyed 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, do not bind or grip the parts and are extremely sensitive to fine tolerances. The basic unit works on a fixed speed; however, Elscint can also offer a sensor and a variable speed AC or DC motor fitted with an Elscint reduction unit.
This unit offers a high degree of flexibility and can also be used for sorting and grading of balls, taper rollers, pins and similar components.
