Pulverulent substance dispensing device for capsule filling machines

Abstract

The dispensing device comprises a powder feeding container (1), an intermittently rotating body (7) provided with a circular channel (6) which receives the powder from the container (1) and is provided in its base with groups (X) of holes (9, 9A) alternately alignable with holes (12, 12A) present in an underlying intermittently rotating forming cylinder, a stationary closure member (10) lying below the rotating body (7) and comprising a series of holes (10B), a movable multiple pusher means (15, 16, 17, 18, 18A) which, when a group (X) of holes of the rotating body (7) become aligned with the holes (10B) of the closure member (10) and with a corresponding number of holes (12, 12A) of the forming cylinder (11), traverses the circular channel (6) and said aligned holes to feed into and compress within the holes (12, 12A) of the forming cylinder (11) given quantities of powder, which said forming cylinder conveys, compressed, into a position coinciding with a capsule base (2) which is aligned with a hole (12) of said forming cylinder (11) and where the multiple pusher means transfers a compacted measure of powder into the capsule base (2), the multiple pusher means comprising three presser members (15, 16, 17) for transferring and compressing the powder, and an expulsion member (18) for transferring the compressed powder mass into the capsule base (2).
