Abstract
The correlation between the size of commercial capsules and that of drop holes of the capsule supply apparatus was studied by a geometric analysis on automatic tablet packaging machine (type OMP-CAT-150). The following results were obtained from the calculation of the sizes of capsules and drop holes: 1) Suitable ranges of length and diameter of capsules were formularized under the setting of constant height and diameter of drop holes, as follows:{8-2√6/5}·b<B<b-√2b·B-b2+B/2-a<A<awhere A, B, a and b are capsule length, capsule diameter, drop hole height and hole diameter, respectively. 2) Commercial capsules are classified into six groups by their size. It can, therefore, be expected that the automatic tablet packaging machine is miniaturized by reducing the varieties of capsule supply apparatus.
