the device shown in fig1 and 2 possesses a rotor 1 driven by a motor not shown in any detail here which rotor can be set into rotary motion in rotating direction a in accordance with fig2 . on this rotor , in horizontal alignment , are fitted two compacting tools 2 , 4 which in each case are movable in relation to one another . the compacting tools 2 , 4 are designed in the form of an inner punch 4 and an outer punch 2 which dip into a corresponding borehole of a template 3 . on the circumference of the rotor 1 in the present embodiment , are located four compacting tool pairs which interact with the corresponding templates . on a central axle a of the rotor 1 there is additionally positioned a material filling funnel 5 which rotates together with the rotor 1 . as the rotor i rotates , the outer compacting tool 2 , the outer punch , is moved over an outer guide curve 12 ( fig2 ) in a horizontal plane relative to the rotor 1 . equally , the second compacting tool 4 , the inner punch , is moved over a guide curve 11 in the horizontal plane of the rotor as the rotor 1 rotates . in this way , the compacting tools 2 and 4 take on a different position to one another in dependence on the angle position of the rotor 1 due to the corresponding guide curves . this is made clear by means of the representation in accordance with fig2 . in position i , the two compacting tools are at a large distance from one another . here , the tabletting material is filled in and dosed . in position ii , the compacting tools 2 and 4 are moved closer to one another . here the tabletting material is increasingly compressed . to apply the required compacting force , two pressure rollers 6 and 8 are positioned opposite each other here . in this position , the pre - compacting of the tablet or compact is performed within template 3 . in position iii , the compacting tools 2 and 4 are moved even closer together so that the tabletting material is compressed even further . here the final compacting pressure to form the tablet is achieved . the final compacting pressure is applied by the pressure roller 6 and the pressure roller 7 ( fig2 ). finally , the compacting tools are moved by the curve control in such a way that the finished tablet or compact is ejected from the template . this ejection position is marked by iv in fig2 . the pressure rollers 6 , 7 and 8 are designed to be movable . the pressure roller 6 positioned in the central area of the rotor 1 is located eccentrically to the axle a of the rotor 1 here and is adjustable in its eccentricity . the pressure rollers 7 and 8 are each adjustable in their distance to the rotor 1 . thanks to this adjustability , the compacting forces to form the tablet or compact can be varied . basically , the pressure rollers 6 , 7 and 8 serve , as described above , to generate the required compacting forces and to transfer these to the compacting tools . in this process , at each passage of the compacting tool pair 2 , 4 between the pressure rollers 6 and 8 and 6 and 7 associated therewith in each case , a packing of the template contents takes place . the filling means 5 in the embodiment shown here is designed as a filling funnel with a convex design , with the funnel shape being obtained by a cone located in the interior of the filling funnel . funnel - like tapering channels 9 are formed between the filling funnel 5 and corresponding filling apertures 10 in the templates 3 . due to the centrifugal forces which apply to the tabletting material particles located in the tapering ends as a result of the rotation of the filling funnel , a safe transport and so filling of the templates 3 is ensured at position i . in fig3 to 5 , different working positions of the compacting tools 2 and 4 in relation to each other are shown in each case . in fig3 the phase of template filling is shown . this representation corresponds to position i in fig2 . in fig4 the compression of the tabletting material is shown . this phase 2 corresponds to positions ii and iii of fig2 . finally , fig5 shows the ejecting of the finished tablet t . phase 3 corresponds to position iv in fig2 . it becomes clear here that the finished tablet t can fall down due to gravity through a corresponding slot 13 into a collecting box not shown in any detail here .
the invention relates to a device for the manufacture of tablets or compacts with at least two compacting tools which in each case can be moved in relation to one another and at least one template interacting with these and with a filling arrangement to feed the tabletting material into the template . in accordance with the invention , the compacting tools movable in relation to one another are aligned horizontally .
