Title:
TABLET SPLITTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2013/024903
Kind Code:
A1
Abstract:
The present invention makes it possible to automatically adjust the groove depth of a drop route for a tablet, even though the thickness of the tablet may not be known. The present invention is provided with: a dropping tablet guidance member (31) where a groove-shaped tablet drop route (32) is formed from an upper end to a lower end; a receiving member (34) for temporarily holding a tablet (10) that has fallen through the tablet drop route (32) at a slicing position (33) midway on the tablet drop route, by opening and closing the route; a slicing mechanism (40) for slicing the tablet at the slicing position (33); a groove depth regulation member (37) for covering an upstream portion route (32a) of the tablet drop route (32); a thickness adjustment mechanism (38) for expanding or contracting the relative distance (G) between the groove bottom of the tablet drop route (32) and a groove bottom-facing surface of the groove depth regulation member (37); a tablet passage detecting means (39) for detecting the passage of the tablet through the upstream portion route (32a); and a control device (23) for operating the thickness adjustment mechanism (38) while monitoring the detection result to adapt the relative distance (G) to the thickness of the tablet. During slicing, an adjustment in which the predetermined time for speed change or hold release is adapted to the thickness of the tablet is also automatically carried out, through the detection of the drive current of the opposed blade (41).
