ABSTRACT:
A verification system for capsules, tablets and the like includes a test block having a slot through which the capsules are directed by a conveyor. The test block includes first and second spaced sensing planes each having bifurcated fiber optic input and output arrays on the top and both sides of the slot. An optical system provides a planar light beam for sensing the position of the capsules being tested at the output from the test block. The length of the capsule is determined from the speed of the conveyor and the time of interruption of planar light beam. If the capsule is not of the proper colors and length, it is pneumatically ejected into a rejection chute.
