Apparatus for sorting hard gelatine capsules.

摘要

The apparatus makes use of a pair of rotating combs (11-14), the discs of the second comb being interposed between the discs of the first comb and positioned at the top between fixed guide plates (17). The discs of the first comb intercept the streams of closed capsules, from which any covers not provided with shells have already been removed. The capsules are inserted by their shells between the discs of the first comb and remain suspended on said discs by their covers (C1). Only capsule shells and any crushed capsules fall through the discs of the first comb. The capsules conveyed by the first rotating comb arrive on the discs of the second comb, generally with their covers at the front. The second comb transfers the capsules to the longitudinal guide channels (107') of a short vibrating table (7'), which in the initial part of each channel is provided with a longitudinal aperture (19) which allows the capsule shell to pass through but holds the capsule covers, which in this way arrive in a vertical position at a discharge hole (20). Any capsules carrying two covers pass over said hole (20) and are discharged into the hopper for rejects.
