An apparatus for filling tablets into blister packages, including a lower assembly which provides a vibrating guide for directing elongate thermoplastic strips longitudinally through the apparatus. A movable carriage reciprocates above the lower assembly and carries a plurality of brushes in rotary contact with the top surface of the thermoplastic strips of material. A portion of said brushes are transversely disposed with respect to the elongate thermoplastic strips and are rotatively journalled within the carriage assembly. Other of said brushes circularly rotate with respect to the elongate strips and combine with the transverse brushes to thoroughly sweep the entire top surface of the strips to urge medicinal tablets and the like into depending blisters which are formed in the thermoplastic strips.
An installation for packaging tablets in a blister strip moving beneath a bulk feed device for tablets, the installation includes a distribution system comprising a mounting stand (1) for motorized control elements which has an attachment surface (100) provided with at least two sets of fixing members (41, 42) for detachably mounting thereon at least two interchangeable distribution units, each in working relationship with at least some of said motorized control elements in order to drive corresponding parts to execute the distribution of the tablets between the bulk feed device and the blister strip. Such interchangeable units may preferably include at least one dispersion-based distribution unit with rotating brushes in succession above the travel path of the blister strip, and at least one channel-based distribution unit with descending guide ramps for the tablets.
A blister packaging machine comprises a forming station in which a plurality of cup-shaped depressions can be formed into a bottom sheet, a filing station, in which a product can be filled into the cup-shaped depressions, and a downstream sealing station, in which a cover sheet can be sealed onto the bottom sheet. The filling station comprises a brush box disposed above the bottom sheet, in which several rotatably driven roller brushes are disposed parallel to each other. The roller brushes are connected to a rotary drive which is received in a drive gearbox disposed next to the brush box. A magnetic coupling is thereby provided for transmitting a drive motion of the rotary drive to the roller brushes through a wall of the drive gearbox.
