A new low-cost automatic inspection machine sorts small parts based on pre-programmed dimensional tolerances such as length, width, or diameter. The J181-T automatic parts sorter from Resec Systems, Inc., Bergenfield, N.J., costs $21,000, much less than competitive units. It comes in models for parts from 0.25 to 2 in. It inspects and sorts up to 3600 parts/hr with a measurement accuracy of ±0.0001 in. Parts are fed by a vibratory bowl feeder onto a gravity track, which separates and places them individually under a digital video camera for inspection. The camera captures the image of each part, and the system measures the pre-programmed features and places the part in the appropriate bin. The unit can be programmed for multiple part shapes.
