Definitions

  • the invention relates to a rotary press according to the preamble of patent claim 1.
  • Rotary presses for the production of tablets and other compacts have long been known. They generally have a rotatably driven about a vertical axis of rotation rotor having a die plate with arranged on a pitch circle die holes and lower and upper punches and guides for it.
  • the rotary press also includes cams for upper and lower punches and at least one pressing station with upper and lower pressure roller.
  • a rotary press is equipped with a filling device which automatically fills material to be pressed in the die holes and a scraper, which strips the ejected from the lower punches pressed bricks from the top of the die plate into a drainage channel. At the end of the drainage channel is a filling device.
  • the compacts can also be directed to a testing station.
  • the invention has for its object to provide a rotary press in which the compacts can be removed at a desired location on the circumference of the rotor.
  • the rotor is provided radially outside the pitch circle for the die holes with an annular surface which preferably extends horizontally and which is concentric with the axis of rotation of the rotor.
  • the annular surface is lowered relative to the top of the die plate by a predetermined amount.
  • First deflection means deflect the compacts ejected from the die bores towards the annular surface
  • second deflection means deflect the compacts outwardly from the annular surface to a discharge channel.
  • the compact is directed to the lower annular surface, it can move unmolested by a pressing station or filling device and then out with the help of the second stripping means at a desired location to the outside.
  • the rotary press according to the invention has the advantage that the compacts can be converted at any point regardless of their process facilities in processes. A special drive is not required for this.
  • the invention is particularly advantageous for multiple rotary presses, because thereby the removal of the compacts can be made at only one location on the circumference of the rotor. Peripheral devices are therefore only necessary on one side of the press.
  • the space required for the installation of the rotary press according to the invention, for the peripherals and possibly a container in the application of a compact container is minimal.
  • a rotor 10 of a double rotary press is shown in FIGS. 1 and 2, which is reproduced only in intimations.
  • the rotor can be driven in rotation about a vertical axis (in FIG. 1 perpendicular to the plane of the drawing) by means of a rotary drive.
  • the rotor 10 includes upper and lower punches, which are guided in punch guides. Both are also not drawn.
  • the rotor has a die plate 12, which has a number of die holes on a pitch circle 14.
  • the Matrizenbohrept are not shown, but only the compacts, which are rectangular in the present embodiment.
  • the rotor 10 is associated with a first filling device 16, by means of which powder to be pressed is introduced into the die bores.
  • the rotor rotates in the embodiment opposite to the clockwise direction.
  • a Vorpreßstation 18 and a Hauptpreßstation 20 are assigned, of which in each case an upper pressure roller 22 and 24 can be seen.
  • the pressure rollers are known to interact with the dies to press the material into the die bores.
  • a second filling device 26 is the first diametrically opposite and follow it in the direction of rotation, a second Vorpreßstation 28 and a Hauptpreßstation 30, of which only the upper pressure roller 32 and 34 can be seen.
  • annular surface 36 is provided on the rotor 10 which is concentric with the axis of rotation and is lower than the top of the die plate 12th
  • a baffle 38 is disposed a little above the die plate. It serves to direct the first compacts 40 ejected from the lower punches from the upper side of the die plate 12 to the annular surface 36. As a result, the first compacts 40 move freely through the first filling device 16 and the first Vorpreßstation 18 and the first Hauptpreßstation 20.
  • a second, located just above the horizontal annular surface 36 deflection section 42 directs the first compacts 40 from the annular surface 36 in a first outlet channel 44th
  • a third deflecting section 46 in the form of a scraper is provided which deflects second compacts 48 from the upper side of the die plate 12 into a second outlet channel 50, which is arranged parallel to the first channel 44.
  • the first compacts 40 are produced in the first pressing station 28, 30 and ejected behind the Hauptpreßstation 30 and then directed to the annular surface 36.
  • the second compacts 48 are produced in the second pressing station 18, 20 and the ejected compacts are usually directed by the scraper 46 in the outlet channel 50.
  • the compacts 40 on the annular surface 36 are, as described, directed into the outlet channel 44.
