Definitions

  • the invention relates to a method for the test squeezing of at least two layers of tablets according to claim 1 in the experimental squeeze of coated tablets according to claim 2 and an apparatus for performing the method according to claim 6.
  • Rotary tablet presses are known to have a rotary drive driven rotor having a die plate, top and bottom punches guided in respective guides and having a cam system. Furthermore, at least one pressing station is provided, which usually has an upper and lower pressure roller, with the aid of which upper and lower punches are pressed into the matrix in when you pass the pressing station. Usually, two pairs of pressure rollers are provided for pre and final pressing of the material. Finally, a filling device is provided, by means of which the material to be pressed is filled into the die holes. The rotor is continuously rotated, with the filling device constantly filling material into the associated die bores and the associated lower punch ejects the finished pressed tablet from the die bore, from where it is guided by means of a scraper in a channel.
  • multilayer tablets with such rotary tablet presses.
  • the multilayer tablets are produced in one revolution of the rotor, wherein one filling device per layer and a pressure roller assembly (pressing station) is provided. If z. B. produces a three-layer tablet, three filling devices are provided at 180 ° distance and three pressing stations with at least one pressure roller pair between the filling devices.
  • coated tablets It is also known to produce so-called coated tablets with the aid of a rotary press. Under coated tablets is usually understood a two-layer tablet in which a core is disposed between the layers. After filling and pressing the first layer, a core of another material is placed on the first layer and then a second layer is filled. In the production of such coated tablets can be proceeded in various ways. It is conceivable to refill the first layer and to carry out a compression only when the second layer is filled. Alternatively, the first layer can be pressed before the core is inserted. Subsequently, the compression of both layers with core. Finally, it is also possible to press the core after insertion a degree in the first layer. This can also be done with the upper punch in the pressing station. The processes described can take place during one revolution of the rotor.
  • the rotor is rotated and accelerated so that it has the desired production speed in the printing station. After one revolution, the rotor is stopped in the filling position. During the rotation of the rotor signals or waveforms of the measuring points are recorded and placed in a computer for display and evaluation.
  • the invention is therefore based on the object of specifying a method for the test extrusion of multilayer or coated tablets which on the one hand can be carried out under production conditions and on the other hand manages with a low press material expenditure.
  • the rotor is provided with only one pair of punches and with the aid of the operating computer and control computer, the rotor can be moved to a defined filling position in which the pair of punches is in this position.
  • the lower punch is in a first fill position while the ejector cam is in an inactive position.
  • the template is filled with the material for the first layer.
  • the pressure rollers have taken a first printing position in the pressing station.
  • the adjustment of the control cams and the pressure rollers is done with the aid of suitable adjusting drives, such as a hydraulic or pneumatic or electromechanical drive.
  • the rotor is rotated by one turn until the pair of dies has reached the filling position again. This is done a pressing of the first layer of the multilayer tablet. Since the ejection cam has been in an inactive position, the first layer is not expelled, but remains in the die bore. After reaching the filling position again, the filling curve is brought into a position in which a metered filling of the second layer of the multilayer tablet can take place.
  • the pressure rollers are brought into a second printing position. Further, the ejector curve is brought into an ejector position when only a two-layer tablet is to be produced. During the second revolution of the rotor, therefore, the second layer is pressed and ejected the two-layer tablet through the Auswerferkurve and the associated lower punch. For the production of a multilayer tablet with n layers therefore n rotations of the rotor d. H. One revolution per shift required with each individual adjustment of the cams and the pressure rollers.
  • the signals of the individual measuring points, z. B. for the pressing force recorded and fed to a control computer for display and evaluation.
  • the measured signals serve z. B. for determining the compression characteristic of the press material.
  • the process for producing a coated tablet is similar to the method according to claim 1.
  • the core is inserted. This can be pressed in a further revolution of the rotor with the help of the upper punch a little in the lower layer.
  • the filling of the press material and the core can be done by hand.
  • a filling device for example, a filling device rotatable about a vertical axis, which has a chamber for receiving a layer material per layer of the multilayer tablets.
  • a rotary drive Upon rotation of the filling device by means of z. B. a rotary drive, in each case a filling outlet of a chamber is aligned with the die bore in the filling position.
  • the inventive method has a number of advantages. Press tests could be carried out with a rotor fitted with only one pair of punches, with or without dummy dies. The changeover times to other press materials or other stamp types is very short. In the press trials, a low dust formation, since only small amounts of material are used.
  • All process-relevant settings can be adjusted and tested in the press trials: speed of the rotor, pressing force in the press station, thickness, hardness and weight of the tablets, etc.
  • the data determined in the press trial and various settings can be transferred directly to a production rotary press, such as z. As the speed, the pressing force, thickness, hardness, weight of the tablets, etc.
  • the measurement data for each pressing process are available directly and can be displayed in the operating computer, evaluated and stored with all process-related data.
  • a rotor 10 of a rotary tablet press is indicated with a die plate 12 having a plurality of die holes 14 on a pitch circle.
  • the rotor 10 is driven by a suitable rotary drive, which in turn is controlled by an operating computer and control computer (not shown).
  • the rotor 10 are two pressing stations 16, 18 associated with upper and lower pressure roller, in each case only an upper pressure roller 20 and 22 can be seen. With the help of the pairs of pressure rollers, upper and lower punches are pressed into the die bores 14 when they pass over or under the pressure rollers in order to press the material located in the die bore.
  • the rotor is associated with only one pair of punches, namely upper and lower punches, which in turn are associated with only one die bore 14.
  • the pair of dies is not shown in Fig. 1.
  • the rotor 10 is associated with a filling device 24. It is rotatable about a vertical axis, as indicated by the arrow 26. The rotation can be done by means of a suitable, not shown here rotary drive.
  • the filling device 24 has three filling chambers 28 arranged at 180 ° intervals on, the filling output can be aligned depending on the rotational position to a die bore 14. In the manufacture of a three-layer tablet, each filling chamber 28 is filled with a material for a layer of the three-layer tablet.
  • Fig. 2 the above-mentioned press-stamp pair is shown seven times.
  • the upper punch is denoted by 30 and the lower punch by 32. It also recognizes the die 34 with the die bore 14, which are associated with the punches 30, 32.
  • the seven positions shown in Fig. 2 correspond to three revolutions of the rotor 10.
  • position 1 the pair of punches 30, 32 are in the filling position, and the rotor 10 is at a standstill.
  • a first quantity of material 36 is filled into the die bore 14. The amount is therefore determined by the position of the lower punch 32, which is brought with a filling curve 38 in the desired position.
  • the pressing process takes place in which the press-punches 30, 32 pass between the upper pressure roller 18 and the lower pressure roller 19 (in FIG. 2, for the sake of simplicity, the pressure roller pair of the pressing station 16 in FIG. 1 omitted.)
  • position 2 the first layer of a three-layer tablet is thus pressed.
  • the rotor 10 is stopped again in the filling position of the press-punches 30, 32 and it is filled with the material 38 for the second layer.
  • the second layer is pressed, and in position 5, the filling is carried out with a third layer of material 40, which is also pressed in position 6 to form a multilayer tablet, which is designated in position 7 at 42 and the lower punch 32 is ejected from the die bore.
  • an ejector 44 is provided.
  • filling curve 38 and pressure rollers 18, 19 are set in the desired manner in order to specify the required pressing parameters.
  • the adjustment is made by means of suitable adjustment drives, which are not shown here. However, it is understood that, depending on the number of desired over-rotation very well an adjustment before the next revolution of the rotor and the next pressing process takes place.
  • the Auswerferkurve 44 also has an adjustment (not shown), which adjusts the Auswerferkurve 44 during the first two revolutions of FIG. 2 in an inactive position to avoid ejection of the previously pressed layers.
  • the control of the individual adjusting drives and the rotary drive for the rotor 10 and the filling device 24 is carried out by an operating computer and control computer such that, after appropriate programming or before setting, these processes take place automatically.
