  • the invention relates to a rotary press, especially for the production of tablets, with a Frame, a rotor with drive, at least one Pressure roller unit and a housing.
  • Rotary presses consist of a frame, a rotor with drive, upper and lower rockers, which guide the upper and lower pressure rollers, a frame housing, corner connectors and a head plate consist.
  • the forces occurring in the pressing process are about the stamp and the wings in the headstock and initiated the frame immediately and excite these membrane-like components by the pressing forces to vibrations, which in turn leads to considerable noise emissions to lead.
  • a rotary press of the generic type is out the US-PS 3,891,375 previously known.
  • the Base frame made of a rectangular frame, on the The rotor is mounted on the upper frame plate consists of brackets screwed onto the frame, which carry a control unit above the rotor.
  • the pressure roller units are frame-like and on the side, screwed to the frame Carriers stored.
  • the disadvantage here is the absorption of the compressive forces of the two pressure roller units from which the housing forming supports, which makes it suitable for high loads to deformation of the housing and related Vibrations and noise of the housing comes.
  • the invention is therefore based on the object a rotary press of the generic type in this regard to improve the inclusion of the in the Forces introduced by pressure rollers is improved and which works with less vibrations and less noise.
  • the invention provides that one the rotor with drive and the pressure roller unit absorbing solid, bending and torsion resistant base plate picked up from the base frame by means of elastic bearings is, the rigidity of this elastic Bearings and the mass of this complete press cell on each other are tuned that the natural frequency of this Vibration system in all six possible degrees of freedom much smaller than the lowest The lowest stamp engagement frequency occurring at the speed as the excitation frequency.
  • the complete press cell will thereby excited supercritically during the pressing process.
  • An impact from dynamic forces from the pressing process not on components of the rotary press arranged on the base plate almost does not take place. That’s how she works Tablet press low vibration and low noise and can nevertheless transmit large pressing forces.
  • the housing is only connected to the base frame and compared to the base plate by means of smaller ones supported elastic bearing, the stiffness of the elastic bearing is chosen so that from the connected Mass and stiffness of the elastic The resulting natural frequency is much lower than the lowest punch engagement frequency. So there are almost no vibrations and therefore almost no noise from the press forces Vibrations excited parts, such as rotor with drive and pressure roller unit, transferred to the housing.
  • the housing is designed so that the upper Head part of the machine receiving part of this housing extends over the entire height of the machine and the machine is limited on one vertical side.
  • This housing segment is preferably used for recording the main electric drive, the incoming and outgoing connection lines, the supply units and the supply lines of the machine.
  • a wall separates this supply side of the rotary press from the clean room side of the press cell.
  • the elastic bearings are as two metallic bearing elements and one connecting them elastic buffer trained.
  • Such elastic bearings are under the SCHWINGMETALL brand from the company Continental.
  • the rotary press comprises a massive, bending and torsionally rigid base plate 1, a rotor 2, a Pressure roller unit 3 and a drive motor 4, the are stored on the solid base plate 1, and a base frame 6 standing on elastic feet 5, on which the massive base plate 1 by means of elastic Bearing 7 is mounted, and a surrounding these components Housing 8 that by means of smaller elastic bearings 9 is connected to the base frame 6.
  • a bearing bush 11 for the axis 12 of here Not shown rotor 2 arranged on the solid base plate 1 a bearing bush 11 for the axis 12 of here Not shown rotor 2 arranged.
  • the axis 12 of the rotor 2 carries on the underside of the base plate 1 a toothed belt pulley 13.
  • the pressure roller unit 3 is included upper and lower pressure roller 14, 15 adjustable stored.
  • the massive one Base plate 1 attached drive motor 4 with on the Bottom toothed belt pinion 16, with a Toothed belt 17 around the toothed belt pulley 13 for the Rotor 2 and the toothed belt pinion 16 put around and is tensioned by a spring washer 18.
  • elastic bearings 7 support the massive base plate 1 on the base frame 6 shown in FIG. 1 elastic bearings 7 are made of two metallic bearing elements 19, 20 and an elastic connecting them Buffer 21 formed.
  • the elastic bearings 7 are under the brand SCHWINGMETALL from Continental customary.
  • Fig. 3 shows the bottom view of the massive, bending and torsionally rigid base plate 1 with the four elastic bearings 7, the rotor 2 driving large toothed belt pulley 13, which from the drive motor 4th driven toothed belt pinion 16 and the toothed belt 17 exciting clamping washer 18.
  • Under one Angle of approximately 35 ° to the longitudinal axis 22 of the base plate 1 extend elongated holes 23, the receiving and Storage each serve a pressure roller unit 3, the is described in more detail below with reference to FIG. 4.
