Patent ID: 7000368

Claim:
An apparatus for sealing cylindrical capsules formed of a body and of a cap inserted axially inside one another, comprising means to feed capsules positioned to be sealed, means to distribute a liquid sealing solution along the rim of the cap of each capsule and a computerized microprocessor control unit designed to coordinate the movement of the members of the apparatus, further including: a first and a second horizontally circular platform-shaped supports angularly movable in steps, each provided with seats designed to contain the capsules to be sealed, the seats of said second circular platform-shaped support being in a much larger number than the seats of said first circular platform-shaped support and said second circular platform-shaped support partially underlying said first circular platform-shaped support; for each circular platform-shaped support, respective means for stepped angular feed; means to transfer the capsules from said first circular platform-shaped support to said second rigid circular platform-shaped support; and means to unload the sealed capsules from said second circular platform-shaped movable support; a plurality of through apertures provided in each circular platform-shaped support, distributed regularly according to coaxial circumferences to form said seats for said capsules, each revolving circular platform-shaped support being superimposed and moved close to a respective fixed table designed to prevent the capsules from being dropped from said apertures, wherein said means to distribute the sealing solution include, for each row of apertures of said first circular platform-shaped support, a distributor disk partially immersed in a container containing the liquid sealing solution, said disk, through an aperture produced in said table underlying said first circular platform-shaped support at the level of each circular row of apertures coming, with stepped rotation of said first circular platform-shaped support, into contact successively with the capsules disposed inside the apertures of said first circular platform-shaped support, raising them slightly and said means to distribute the sealing solution include a pressure roller rotating together with said disk, in the same direction and at the same peripheral speed as said disk, said roller being carried by an oscillating element designed to place it on the capsule to be sealed on the opposite side of the respective distributor disk, to provide the capsules together with said disk with a rotating movement to allow said disk to uniformly transfer the liquid solution to the entire periphery of the rim of the cap of the capsule.
