  • the invention relates to a method for controlling the rotor speed of a rotor of a rotary tablet press, wherein the rotor has a rotary drive for rotating the rotor, a rotatable with the rotor die plate having a plurality of cavities and a plurality of also rotating with the rotor upper and lower punches, which are assigned in pairs to a cavity of the die plate for pressing filler material in the cavity into a compact, wherein a rotational speed controller controls the rotational drive of the rotor based on a comparison of a measured rotor rotational speed with a nominal rotational speed value.
  • the invention also relates to a rotary tablet press comprising a rotor with a rotary drive for rotating the rotor, a rotatable with the rotor die plate with a plurality of cavities and a plurality of also rotating with the rotor upper and lower punches, the pair of a cavity of the die plate for Compressing filler in the cavity are assigned to a compact, further comprising a speed controller which is adapted to control the rotational drive of the rotor based on a comparison of a measured rotor speed with a target speed value.
  • the speed controller reliably provides a constant rotor speed in standard operation of a rotary tablet press at rotor speeds of, for example, more than 60 rpm.
  • rotor speeds for example, more than 60 rpm.
  • the invention is therefore an object of the invention to provide a method and a rotary table press of the type mentioned, with which even at low rotor speeds a reliable operation at any time with constant process result without unwanted noise is possible.
  • the invention solves the problem in that an additional target torque for controlling the rotary drive is provided as feedforward control on the basis of directly or indirectly determined pressing force values of upper and / or lower punches.
  • the invention correspondingly achieves the object by further providing a pilot control device which is designed as a pilot control on the basis of directly or indirectly determined pressing force values of upper and / or lower punches an additional setpoint torque for controlling the rotary drive provide.
  • the invention is used in a rotary tablet press for use with a rotor which is rotationally driven by a rotary drive.
  • the rotor has a co-rotating during the rotation of the die plate with a plurality of cavities, in which is filled in the operation to be tabletted usually powdery filling material.
  • the cavities can directly through Holes are formed in the die plate. But they can also be formed by inserted into the die plate die sleeves.
  • the die plate may be a one-piece annular disk or consist of a plurality of ring segments.
  • the rotor further has a plurality of likewise rotating with the rotor upper and lower punches. Each pair of upper and lower punches is associated with a cavity of the die plate and runs with this.
  • the rotary tablet press may include a pre-press station and a main press station.
  • the pre-press station the filling material is pre-pressed and in the main press station the filling material is pressed into the finished tablet.
  • the main press station it is also possible to provide a plurality of pressing stations, in particular a plurality of pre-pressing stations and a plurality of main pressing stations.
  • Each press station can have upper and lower pressure rollers which press the upper and lower punches into the cavities. This structure of a rotary tablet press is known per se.
  • a speed controller of the rotary tablet press compares a measured speed, which can be made available to the speed controller as an input variable, for example, with a target speed value for the rotor speed given to the speed controller. If the speed controller detects a deviation here, the speed controller activates the rotary drive to readjust the measured speed to the setpoint speed value. In the case of the method according to the invention or the rotary tablet press according to the invention, this speed control can take place permanently during operation of the rotary tablet press.
  • the rotational speed can be detected, for example, by a rotational speed sensor provided on the rotary drive or the rotor.
  • the predetermined target speed value may be different process conditions, such as the depending on the pressing material, the tablet size or the placement of the rotary tablet press.
  • the present invention is based on the finding that at higher speeds of the rotary tablet press, for example 60 U / min of the speed controller due to the high moment of inertia of, for example, more than 100 kg heavy rotor only the constant friction torque of the pressing stations, especially the upper and lower punches in the Cavities pressing pressure rollers, must balance.
  • the momentum of the rotor is sufficient to pass the upper and lower punches past the pressure rollers.
  • the speed controller must therefore only slightly readjust at high rotor speeds, so that the rotor speed can be easily maintained constant.
  • the invention is further based on the idea that at low speeds, for example 20 rpm or less, the rotational energy of the rotor is no longer sufficient to guide the upper and lower punches past the pressure rollers. This results in a significant fall in speed when a pair of upper and lower punches come in contact with a pressure roller pair.
  • the speed controller first has to determine a speed error for intervention.
  • the speed governor greatly modulates to readjust the rotor speed to the desired speed value. Due to the associated time delay of the speed controller provides a much higher drive torque for the rotary drive available when the previously came into contact with the pressure rollers pair of upper and lower punches already comes out of the contact area with the pressure rollers out.
  • the invention provides a precontrol on the basis of pressing force values of upper and / or lower punches.
  • pressing force values of at least one upper punch and / or at least one lower punch preferably a plurality of upper and / or lower punch, more preferably determined by all upper and / or lower punches.
  • the press force values are measured during the pressing process for pressing the filling material in the cavity.
  • the press force values are thus determined in particular when the upper and / or lower punches are in contact with pressure rollers of the pressing station (s) of the rotary tablet press.
  • the press force measurement can be carried out at all pressing stations of the rotary tablet press.
  • prepress and main press stations can be provided, with prepress rollers and main pressure rollers. Accordingly, the press force measurement then take place at the pre-press station (upper and / or lower pre-pressure rollers) and / or at the main press station (upper and / or lower main pressure rollers). In principle, it is sufficient to perform a press force measurement on each pressing station on a pressure roller, that is to say on the upper or lower pressure roller. Based on the pressing force measurement, a determination of the expected load torque for the rotary drive when passing through the pressing stations, in particular the pressure rollers. This expected load torque is given to the rotary drive control in the form of additional target torque as a pilot control variable. The rotary drive is thus controlled so that it also applies the toastsolldreoment torque in addition to the torque required to achieve the desired speed.
  • the invention is based on the idea that the pressing forces occurring during the pressing of tablets in rotary tablet presses are proportional to the torque to be applied by the rotary drive to the rotor. In particular, at low speeds, when the rotational energy of the rotor is not sufficient to push the upper and lower punches under the pressure rollers, can be determined in this way the extent required additional torque.
  • the invention is further based on the idea that the friction torque occurring during a rotation of the rotor, in particular of the pressure rollers, is essentially constant.
  • a (highly) dynamically changing torque is variable, caused by the upper and lower punches coming alternately into contact with the pressure rollers and leaving the contact with the pressure rollers.
  • this dynamically changing torque is compensated by the high rotational energy of the rotor.
  • the speed controller therefore only has to compensate for the constant friction torque. While in the invention, the speed controller continues to compensate for this constant friction torque, so as to keep the speed constant, the feedforward control according to the invention ensures that the dynamic torque is compensated by the pressing operations safely and evenly, even if the rotational energy of the rotor is not sufficient for this purpose.
  • the rotational speed therefore does not break at the beginning of contact between the upper and lower punches and the pressure rollers and does not increase beyond the setpoint rotational speed value when the upper and lower punches exiting the pressure rollers.
  • the rotational drive is already given by the pilot control the expected in the course of the process load torque as Saksollwindmoment so that the rotor speed can be kept safe even at low speeds and high press forces safely.
  • the control of the rotary drive already adapts the required torque due to the pre-control before a significant deviation of the measured speed from the setpoint speed value occurs. It thus does not come to the explained speed fluctuations and the associated shaking the rotary tablet press.
  • the relevant quality criteria for the pressing process are met, for example, a defined pressure-holding time during pressing.
  • the press runs evenly and quietly, so that the filling of the cavities with filling material is ensured correspondingly constant constant. Press force curves can be set very precisely.
  • the invention can be advantageously retrofitted in existing rotary tablet presses.
  • the control can be done via a fieldbus.
  • the invention is particularly advantageous in galenics, that is, in laboratory operation, when, for example, low rotational speeds are desired, for example, at high pressing forces for experimental purposes and constant experimental parameters are of utmost importance.
  • the pilot control device and / or the speed controller can fall back on a map, a table or a calculation rule.
  • the driving of the rotary drive based on the additional target torque may be performed in accordance with a control ramp, so that the torque of the rotary drive is increased (slowly) according to the ramp. In this way, overshoots can be avoided.
  • the pilot control device or the precontrol can take into account one or more further parameters, such as position of the press force sensors and possible phase offset of the measurement signals, type of press force sensors, type and rated torque of the rotary drive, a speed threshold at which the feedforward control is activated, for example less than 30 U / min, preferably less than 20 U / min, number and size (for example stamp head geometry) of the upper and lower punches, rotor diameter, diameter of the pitch circle of the cavities, equipping the rotary tablet press with upper and lower punches, position of the pressing stations, in particular position of the pressure rollers to each other ,

  • a waivesolldreuderomentprofil expected load profile
  • the rotary drive can be controlled so that it can compensate for the expected during a rotation according to the entry and exit of the upper and lower punches in or out of the pressure rollers load torque in advance. This results in a particularly reliable feedforward control.
  • the inventive method with the inventive Pre-control during operation of the rotary tablet press are performed permanently, for example, as explained above, a speed threshold can be specified, below which the feedforward control is used.
  • the speed controller usually works anyway anyway during operation of the rotary tablet Prés se.
  • a frequency converter can control the rotary drive as a speed controller.
  • the frequency converter can receive the setpoint speed as the first input and the additional setpoint torque as the second input, with the drive controlling the rotary drive based on the setpoint speed and the additional setpoint torque.
  • the frequency converter can determine from the comparison of the target speed value with the actual speed value of the rotor, a target torque to adjust the rotor in its speed to the target speed again.
  • the frequency converter for controlling the rotary drive can also be used to calculate the additional setpoint torque.
  • the additional target torque can be provided by a pilot control device which receives pressing force measured values as an input variable.
  • the pressing force measurement can be carried out by at least one pressing force sensor which is arranged on at least one pressure roller of the rotary tablet press which presses the upper and / or lower punches for pressing the filling material into the cavities. It takes place in this embodiment, therefore, a direct pressing force measurement.
  • the at least one pressing force sensor may be, for example, at least one load cell arranged on the at least one pressure roller of the pressing station (s).
  • Such press force sensors are generally provided in rotary tablet presses anyway, since the pressing force curve as a significant parameter for the Quality assurance is evaluated. Thus, no new sensors need to be installed for the invention.
  • the retrofittability in existing presses is particularly easy, for example as part of a software update.
  • the press force measurement with such press force sensors is a rotation angle-related pressing force measurement, ie position-dependent. It is a precise local assignment possible and thus a particularly reliable feedforward control of the rotary drive.
  • the time value of a specific position does not have to be assigned, as is the case, for example, with a time-resolved press force measurement. This eliminates a source of error.
  • the feedforward control also takes into account any tolerances or deviations between the punches.
  • the feedforward also works reliably in this way, if, for example, in laboratory operation individual pairs of punches are removed, so not all punch positions of the rotor are equipped.
  • the pressing force of all upper and / or lower punches can be determined.
  • the pressing force can be evaluated at all pressing stations, as also already explained. It would also be conceivable to provide the additional target torque for feed forward based on an average of press forces measured for multiple punches of the rotary tablet press.
