Apparatus for sorting pills

摘要

An apparatus for sorting small cylindrical objects has a trough having a longitudinally extending groove along which the objects can slide. The groove is of generally rectangular upwardly open shape and has a pair of upright and horizontally spaced side walls and an upwardly directed floor bridging lower edges of the side walls. The floor is formed offset from the side walls with a vertically throughgoing slot of a width substantially smaller than a predetermined minimum object width so that if any of the objects is of a diameter smaller than the minimum object width it will fall through the slot as it slides along the floor. One of the side walls is formed at the slot with an inwardly directed braking formation engageable with the objects as they slide past the slot to rotate same about vertical axes.
