A method for quality surveillance of powdered press material for a rotary press, in which the press material is fed from a reservoir via a preferably vertical feed channel to a filling device, which continuously fills dies of a rotor with press material wherein to the feed channel and/or the filling device is assigned a microwave resonator with an analysis unit, which measures the moisture and/or the density and/or the size of the granules of the press material, and at least one press variable of the microwave resonator is used for changing a control variable of the rotary press.

Rotary press for quality surveillance of powdered pressed material

A filling apparatus for a rotary tablet press, which itself being arranged stationarily is associated to a circulating die plate of a rotor of the tablet press, with a filling chamber, which features an upper inlet opening for powder-shaped compression material and a filling opening aligned with die bores of the die plate, and with a conveying means in the filling chamber driven by a drive motor, wherein the filling chamber is circular, one single disc-shaped filling wheel is rotatably mounted around a vertical axis in the filling chamber, which has plural wings on the perimeter, spaced apart in the perimeter direction, which sweep over the filling opening upon rotation of the filling wheel, and the inlet opening is arranged in a distance above the filling wheel, preferably approximately centered with the axis of the filling wheel.

Filling apparatus for a rotary tablet press

A rotary press with a stand, a rotor rotatably mounted around a vertical axis in the stand and being driven, which has an upper and a lower compression punch accommodation for upper and lower punches which co-operate with bores of a die plate of the rotor, and upper and lower control cam elements which can be detachably fastened on a cam carrier of the stand and which guide heads of the compression punches by means of control cams during the rotation of the rotor, characterized in that at least one control cam element, guiding the compression punch heads radially outside or radially inside, can be detachably fastened on the carrier and can be moved radially away from the punch heads when the fastening means is detached, so far that by-passing the punch heads, it can be taken out parallel to the axis of the rotor, towards the upside or towards the bottom side, respectively.

Rotary press

Apparatus for the outflow of pressed items from a rotary press, with a first channel section connecting directly to the rotary press, to which at least two channel sections are connected, to which a deflector is attached, which is swivel mounted at an axis almost vertical to the longitudinal extension of the first and/or second channel section and optionally connects the first channel section with one of the other channel sections and a pivot drive for the deflector below or above the channel sections, characterized in that a bearing pin for the deflector is connected in a torque-proof manner with a channel section and the swivel drive is coupled with the deflector via a magnetic coupling eccentric to the bearing pin.

Apparatus for the outflow of pressed items from a rotary press

A rotor for a tablet press including an upper-ram receptacle for the upper rams and a lower-ram guide for the lower rams of the tablet press, as well as a retainer plate having a series of die-bores which are oriented towards the upper and lower rams wherein the retainer plate is composed of at least two ring segments which are adapted to be mounted non-positively and/or positively to the body of the lower-ram guide by means of a fixing device.

Rotor for a tablet press

Rotary press for making tablets with a rotor, which rotor exhibits a die plate and guides for the upper and lower punches, a rotor shaft and an electric drive motor, which electric drive motor rotates the rotor shaft and exhibits a runner and a stator, wherein the runner is disposed directly on the rotor shaft in a torque proof manner or is coupled coaxially with the rotor shaft in a torque proof manner

Rotary press for making tablets

A transfer lock for a tabletting plant, which has a casing with side walls where at least one wall has an aperture which is adapted to be closed by a first flap which is pivotable inwardly into the interior of the casing and is adapted to be locked by a locking device operable from the interior of the casing, wherein the aperture is externally surrounded by a connection profile which is adapted to be sealingly brought together with a counter-profile of a lock channel and the flap externally has a driver profile which interacts with a counter-driver profile of a second flap mounted at the end of the lock channel when the counter-profile of the lock channel is connected to the connection profile, thus allowing to pivot the two flaps into the interior of the casing when the locking device is unlocked, which integrates the connection profile into the material of the casing wall.

Transfer lock for a tabletting plant

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

A tablet rotary compression press for the manufacture of multi-layered tablets, comprising a rotationally driven rotor which has a die-plate with die-plate bores and top and bottom rams aligned towards the die-plate bores which are guided in ram guides of the rotor and are axially actuated by stationary control cams, an insertion device for a portion of the tablet-forming compacts which has two or more arms guided in a radially movable manner at the each end of which a compact is held and can be aligned towards a die-plate bore, wherein said rotor has circumferentially included thereon a support ring or support surfaces on which the compacts can be deposited in the positions approximately aligned towards the die-plate bores, the radial arms are disposed in the rotor, rotate therewith, and have radially movable gripping portions adapted to be radially moved to each other, and the rotor has provided therein a stationary guide with first and second guide cams the cam followers of which are interacted with by the gripping portions in order to grip a compact on the support ring or a support surface, to bring it into alignment with the die-plate bore, and to release it again.

Tablet rotary compressing press for the manufacture of multi-layered tablets

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.

Rotary tablet press
