Definitions

  • the invention relates to an agitator paddle for material supply in die bores of a rotary press, which is modular, to a function change between a 2-chamber filling shoe, comprising a Basierwugelrad, and a 3-chamber filling shoe, comprising a RanSugelrad, a Dosierwugelrad and to allow a Zuzhouerielrad, wherein the Rhakeriel spallschuh comprises no gear for driving the impellers.
  • the invention relates to a rotary press, comprising the modular stirring paddle shoe, wherein the transmission is located to drive the impellers outside the Rrockerielglallschuhs.
  • the invention also includes methods for converting the modular paddle shoe from a 2-chamber fill shoe into a 3-chamber fill shoe and in the reverse direction. The functional conversion of the impeller filling shoe can take place both outside the tablet press and in the mounted state within the tablet press.
  • the invention relates to the field of rotary presses, which are used in the pharmaceutical, technical or chemical industry or in the food industry to produce from powdered materials tablets or compacts in large quantities.
  • Concentric presses are well known in the art. These are characterized by a rotor, comprising an upper and Unterstempel arrangement for receiving punches and a die plate with dies with holes for receiving the powdery material. After filling the die bores, the combination of upper and lower punches can be used to press the material into a compact or a tablet.
  • a so-called gravimetric chamber filling shoe is characterized by an open frame in which baffles and barrages are located.
  • the introduced pressing material is driven by the friction to the die plate, guided by the baffles over the die bores and falls solely by gravity into the die bores passing below the frame. Due to the gravimetric filling, no simple and rapid adaptation to different flow velocities of the powder can take place. For this reason, among other things, hardly any gravimetric chamber filling shoes are used in the pharmaceutical sector today, but instead stirring blade filling shoes are used.
  • Stirrer paddles are motor-driven filling devices in which the material is loaded from above.
  • a material container can be located above the filling shoe, on the head piece of the rotary press, which continuously fill the stirring-blade filling shoe with powder via a material inlet.
  • the impeller filling shoe are usually one, two or three impellers, which convey the powder material from the material inlet by a rotational movement to a filling opening in the Greschuhstoryplatte above the pitch circle of Matrizenbohritch through which the powder enters the holes. This allows a more uniform and precise filling of the die holes can be realized.
  • impeller filling shoes are also referred to as 2-chamber filling shoes.
  • 2-chamber filling shoes are generally constructed as follows: In a filling shoe lower part are in the top circular recesses for the impeller, which is placed on the left, and a metering impeller, which is placed on the right. The directions are based on the mounted filling shoe, whereby a direction of rotation directed towards the center of the rotor is assumed.
  • the Greekteil In the Greekeck is at the level of the pitch circle of holes in the die plate continues to break through in the bottom area, which is referred to as a material outlet or filling opening.
  • an intermediate plate covers the top of the Greschuhunterteils. In it are the two breakthroughs for the drive shafts of the two impellers and the breakthrough for the supply of material.
  • a filling shoe cover rests on the intermediate plate and includes the material inlet, the gear for driving the two impellers and the drive pin for the gear drive.
  • the impellers are driven in the prior art both from the top and from the bottom of the Greschuhgephaseuses. However, in 95% of all rotary presses, the paddle fillers are driven from the top, i.
  • the drive motor is located in the head section of the rotary press. Via a corresponding drive shaft from above, the drive motor is connected to the gear of the Rownerielglallschuhs.
  • the impeller rotates clockwise (looking at the rotary press from above), the metering impeller counterclockwise.
  • the Gear wheel rotates in the same direction at the point of intersection with the pitch circle of the matrices.
  • the pressing material is thus transferred by the Golferielrad from the left side into the filling opening of the Medschuhgroundplatte and passes from there to the middle of the filling opening in the individual die holes.
  • the exchangeable filling curve which subtracts the lower punches below the die surface, for example in a range of 6-22 mm.
  • the press material is thus sucked into the die bore via the withdrawal region of the filling curve.
  • the dosing unit is located in the lower curve. This usually consists of a height-adjustable metering unit with the capture and withdrawal curves and a movable or rigid transfer rail, which is arranged between the filling curve and the metering unit. If, for example, a 10 mm filling curve is used in the rotary press and a net filling of 6 mm is required for the tablet weight, the lower punches are raised by 4 mm after filling by the dosing unit so that a filling volume of 6 mm remains in the die bores.
  • This filling is accordingly as Net filling.
  • the 4 mm pressing material dispensed through the dosing unit are pushed back by the lower punches over the second half of the filling device into the filling opening and thus into the right chamber of the stirring blade filling shoe.
  • this right chamber is the so-called Dosierhoffrad, which rotates counterclockwise and thus transported excess material in the direction of the left impeller.
  • the excess press material returns to the left filling chamber and is there used by the Greflugelrad proportionally for a new filling.
  • a 3-chamber filling shoe is located above the filling and Dosierhofflyer in addition a third chamber in which a third impeller is placed.
  • the third impeller is also referred to as Zubayerielrad.
  • the direction of rotation of the Zuriosflugelrades is of no crucial importance and is therefore used in different ways in the prior art.
  • the material inlet to the feed impeller is offset to a different position than the material outlet into the lower chamber of the filling shoe.
  • the material inlet on an inner pitch circle and the outlet opening for the powdery material are located on an outer pitch circle.
  • the molding material is first fed into the feeding chamber, including the feeding impeller. From there, by the rotation of the Zuzhouerielrades a transport to the chamber of the Greerielrades in an underlying level, which is preferably located on an outer pitch circle. As a result, the material thus falls from the supply chamber into the filling chamber and is taken over by the impeller and brought to the matrix subcircuit, from where it falls through a filling opening in the bottom part of the filling shoe in the die holes.
  • the Zu2010flugelrad thus assumes the function of a rotary valve, which transports regardless of the pressure of the material column permanently the same amount of material in the filling chamber. By adding the third chamber, an excellent tableting result can be achieved regardless of the flow behavior of the press material.
  • the basic structure of the 3-chamber filling device corresponds to that of the 2-chamber filling device, except that above the filling and Dosierhofflrades another chamber for the Zuliteflugelrad is present.
  • a 2-chamber filling shoe in powder materials with a lower flow behavior. In contrast to a 3-chamber filling shoe, this would reduce the energy expenditure. Due to the different material filling in tablet presses, it would thus be desirable to provide a filling shoe, which on the one hand has a particularly high adaptability to the different flow behavior of the powder material and on the other hand is characterized by a low weight and easy removal, for example for cleaning.
  • the invention is therefore based on the object to overcome the disadvantages of the prior art and to provide a filling shoe, which is characterized by a high adaptability to the flow behavior of the powder material and a simple interchangeability.
