ABSTRACT:
Self-rotating and travelling tendency of a circular tablet in its erect posture along an inclined transferring path and an impeding effect upon the tendency which occurs when the tablet is defective one having a breakage or a speckle, are advantageously utilized by the present invention for detecting flaws in tablets and for discriminating the defective tablets from normal ones.
Transferring path bridging equipment in a tablet processing line, is usually composed of a parallel but spaced pair of rails having shoulders on right opposed faces thereof and upper side plates above said shoulders. The shoulders are capable of carrying the tablets thereon or therein between and having an inclination sufficient for giving the normal tablet a self-rotating and travelling tendency along the path in a given direction. The upper side plates are capable of permitting unobstructed passage of the tablet in its erect posture but make it stagnate on the path in a reclined posture.
