A rotary tablet press having a rotatably driven rotor and a die plate with a plurality of die bores. A plurality of upper and lower punches are configured to produce tablets in the plurality of die bores. The tablets are monitored for one or more characteristics and are sorted by an ejection apparatus according to the one or more characteristics into a reject channel and a satisfactory channel.

Rotary tablet press

A die for a rotary compression press, comprising a die holder axially supported in a guide bore and a die insert which is seated in the end-side bore of the die holder via a trunnion-shaped projection and is adapted to be mounted via releasable fastening means, wherein the projection is helically guided in the bore between axially spaced stops and is biased by a spring towards the associated front-end face of the die holder.

Die for a rotary compression press

A rotary compression press for cylindrical compacts, especially tablets, comprising a rotatably driven rotor including a die-plate and an upper and a lower ram guide for upper and lower rams cooperating with the die bores, and a pressure station with an upper and a lower pressure roller for applying a pressing power to the rams wherein the rams circumferentially have an annular tooth system which cooperates with an opposed tooth system in the area of a pressure station for the rams for the purpose of rotating the rams in the die bores thereof, characterized in that the opposed tooth system is defined by a rotatably supported gear which is acted on by a preset braking torque with the braking torque being chosen so as to be smaller than the torque of the ram when under a maximum pressing power.

Rotary compression press

An operating stand for a tablet press device which comprises a process computer with a screen and an input keyboard and where appropriate a printer, wherein the operating lectern is mounted height-adjustable on a traversable base and between the base and the operating lectern there is arranged a linear adjusting drive with a linear guide.

Operating stand for a tablet press device

A rotary tablet press, with a die plate rotatably mounted in a housing, which comprises guides for the upper and lower punch, whose position is controlled by cam disks rigid with the housing, and with an upright drive shaft which is arranged below the die plate and which can be releasably coupled to the die plate, wherein the die plate is formed such that after releasing from the drive shaft and a slight raising it may be moved out laterally, wherein at the ends, facing one another, of the die plate and drive shaft there is provided a quick locking whose parts are arranged in cavities of the die plate and drive shaft and which may be actuated by an actuation rod which is movably mounted in an axial channel of the drive shaft and is actuatable by an actuation device for the selective tensioning or releasing of the die plate and drive shaft.

A rotary tabletting machine with a housing, with a matrix disk in the housing, which in an upper and a lower receiving section guides the upper and lower punch, with an upper and lower cam carrier ring rotationally rigid relative to the housing, for control of the upper and lower punch and with an upright drive shaft, below the matrix disk, driven by a rotational drive and releasably connectable to the matrix disk, wherein the matrix disk and the cam carrier rings with the upper and lower punch after release from the connections as an assembly may be commonly removed from the drive shaft, whereby the cam carrier rings laterally in each case are connected to at least one arm and the arms via an upright connection section are rigidly connected to one another and the connection section is releasably couplable to the housing such that it is secured against rotation.
