Definitions

the invention relates to a rotor for a tablet press according to the preamble of claim 1.
the rotor of a rotary tableting machine typically contains an upper punch holder, a lower punch guide and a die plate.
the lower punch guide takes individual lower punches in bores parallel to the axis on, which are aligned with the die holes of the die plate.
the upper stamp recording receives upper punches in axially parallel bores, which correspond to the Matrix holes are also aligned. Act on the rotation of the rotor Upper and lower punches together with suitable guides or with pressure rollers, so that a compact is produced and ejected.
the upper stamp recording is usually a separate component, while usually lower punch stirring and die plate are formed from a one-piece body.
the conventional design has so far been used in all tableting machines applied. It is also advantageous insofar as matrices and the mounting holes are "standardized" in the die plate for the dies.
dies which are mostly sleeve-shaped are received in mounting holes of the die plate.
the inner contour of the matrices determines the contour of the compact. For the reason above can produce matrices regardless of the number of stations, from the machine manufacturer, from Pitch circle diameters etc. can be used in every tablet press, the conventional ones Standards.
matrices are relatively inexpensive in production.
the invention has for its object a rotor for a tablet press to be improved in such a way that the effort for operating the press is significantly reduced becomes.
the die plate consists of at least two ring segments, which is non-positively and / or positively on the body by means of a fastening device the lower punch guide can be attached.
the die ring segments also axially on the upper punch receptacle, radially on the Lower punch guide or axially and radially attached to the upper punch holder become. It is also possible for the lower stamp guide and upper stamp holder to be in one piece to manufacture.
the design of the rotor according to the invention has several advantages.
the Ring segments can be easily removed from the rotor without a Removal of the rotor as a whole is required. Therefore, the cleaning is designed extremely simple.
a further simplification is obtained in that special dies are no longer required, rather that molding tools are formed directly from the holes in the ring segments. A pollution the holes for the locking screws of the dies can therefore not occur.
Another advantage of quick disassembly and assembly is that easy change from one contour of a compact to the next.
the installation and removal of matrices is also eliminated here, since matrices are used in the invention Rotor no longer need to be used.
This is another one
the advantage connected that more holes are accommodated on a pitch circle can than when using matrices.
the number of dies is limited by the wall thickness of the dies and the radial blind tapped holes for fixing the dies with screws.
the material for the die plate has been determined (e.g. GGG-40, VA cast iron, Steel etc.), which in most cases are hard chrome-plated for reasons of wear becomes.
the matrices can and are made of different materials (hardened Steel, hard metal, ceramics etc.), so that the product contact Surface (top of the die plate) made of different wear-resistant materials composed. This is avoided with the matrix ring segments. in this connection is always the entire product contact surface made of one material.
the top of the matrix ring segments are preferably axially opposed stretched an annular surface that corresponds to the level of the current die plate. At this level, the matrices are filled, the finished tablets are ejected and led out of the machine via a scraper. This ensures that when changing the die ring segments, the setting of the filling device and the tablet scraper need not be changed. This also offers the Possibility the top of the die ring segments z. B. rework when worn, without the level of the top of the die ring segment based on that Filling device, tablet scraper etc. to change.
the top and bottom of the ring segments plane-parallel.
the production of such ring segments is proportionate simple.
the radial surface preferably points downward, so that by pressing the Ring segments against the radial surface the level of the top of the ring segments or the die plate is fixed.
the fastening device can have clamping screws that are axially parallel are arranged and act against the underside of the ring segments to counter this to press the radial surface.
clamping wedges be provided with the help of radially arranged clamping bolts against one Inclined surface of the ring segments and an inclined surface of the body for the lower punch guide fit and thereby tighten the ring segments firmly on the body can.
Fig. 1 is part of a rotor 10 of a tablet press or tableting machine to recognize. It has an upper punch receptacle 12 with receiving bores 14 for upper stamps not shown. It also has a lower punch guide 16 with mounting holes 18 for lower stamps, not shown.
the lower stamp guide 16 is part of a body 20.
the body 20 and the upper punch receptacle 12 are separate parts and are braced against one another via radial surfaces, which, however, is not shown in detail and is known per se.
ring segments 22, 24 are also shown, which with others Ring segments form a die plate 26.
the ring segments 22, 24 have a pitch circle lying holes 28 with which the upper and not shown Collaborate lower stamps for the production of tablets or compacts.
the contour of the bores 28 therefore determines the contour of the compacts.
FIGS. 2 and 3 show a clamping wedge 30 for fastening the ring segment 24 on the body 20 with the help of a clamping screw 32.
the attachment of the Ring segments can be seen more clearly from FIGS. 2 and 3.
the body 20 is facing downward Has radial surface 40 and arranged at right angles to it a cylindrical Circumferential surface 42.
the surfaces 40, 42 serve to precisely define the ring segments 22, 24.
the wedge 30 is shown in FIG. 2, the one with a downward sloping surface 44 of the ring segments and cooperates with an upward sloping surface 46 of the body 20, by pressing radially inwards with the help of the radial clamping screw 32 becomes. In this way, the ring segments become firm against the surfaces 40, 42 excited and thereby get their precise location.
Circumferential spacing bolts 48 are provided against the underside of the ring segments abut and with threaded portions 50 in threaded holes 52 one Sit around rings 54, which is firmly connected to the body 20.
the ring segments can also be bolted tightly against the surfaces 40, 42.
