METHOD AND APPARATUS FOR DETECTING FLAWS IN CIRCULAR TABLET

摘要

The tendency of a rounded tablet to rotate when travelling in an upright or erect position along an inclined transferring path and its tendency not to do so when the tablet is broken or specked, are advantageously utilized by the present invention for detecting flaws in tablet and for selecting the defective tablets from normal ones. According to the present invention, transferring path bridging equipment in tablet processing lines comprises sloped parallel spaced rails having shoulders on sight opposed faces thereof and upper side plates above said shoulders. The shoulders are capable of carrying the tablets thereon or therebetween and are sufficiently inclined such that an undamaged tablet rotates freely along the equipment while a defective or damaged tablet tends to stop along the path and block the tablets behind it. The upper side plates permit unobstructed passage of the tablet in its erect position but inhibit or preclude travel along the path when it is in a reclined or fallen position.
