Definitions

  • the invention relates to a method for quality assurance in tablet manufacture by pressing according to the preamble of the claim 1.
  • An important quality parameter for tablet production is compliance with the given Tablet weight, which with sufficient mixing quality compliance with the limits on the salary Active ingredients guaranteed.
  • the basis for any automatic The control of a tableting machine is the Relationship between measured maximum Pressing force of a tablet and the mass of the Matrix filled goods (tablet weight). It exists thereby a direct connection between the Tablet weight and the one used to manufacture the controlled Tablet necessary pressing force. This connection is used for automatic Monitoring and control devices on rotary presses exploited Depending on the material to be pressed Material is one by the weight of each tablet Pressing tools given tablet shape and one set tablet height a certain pressing force assigned. Now fluctuates with constant tablet height the filling quantity and thus the tablet weight, this results in a direct dependence on a change in the pressing force.
  • EP-0.261.358 B1 describes a method for Quality assurance in the manufacture of tablets described. After that, during manufacturing The tablets are sampled from a variety consist of tablets, their common actual weight value is compared with the target weight value, and where the tabletting machine corresponds to the The deviation between the actual value and the target value is readjusted the tablet weight to the TARGET value bring to. Before readjusting the tablet machine are the weights of each tablet measured and compared the sample. When determining one or more in the weight of the TARGET value the significantly different tablets of the sample Statistics corrected by correction calculation and the corrected value is used for readjustment.
  • the invention is therefore the object based on a quality assurance procedure at To develop tablet manufacture by pressing which all the necessary regulatory mechanisms for Keeping the tablet weight and the tablet height constant and hardness run so that a quick adjustment of deviations is guaranteed and after where the limit values are also automatically optimized can.
  • the weight, the height and the hardness of the tablets is made to fluctuate due to different filling ratios on the Matrices of the press not only after the determination of the Average values from a larger sample can be recorded and only then does a regulation take place, but that tendencies are one in the same direction changing value in time or earlier than can be recorded so far.
  • the invention is based on a the drawing shown exemplary embodiment of the Quality assurance process in tablet manufacturing thanks to a modern high-performance rotary press explained in more detail.
  • the only figure shows a controller model for simultaneous Regulation of tablet parameters weight, height and hardness.
  • the control system is divided into control circuits R1 to R5, which are connected to one another in such a way that they run parallel and nested one inside the other.
  • the first control circuit R1 maintains the actual pressing force PK IST constant at the value of the target pressing force PK target by a change in dosage ⁇ D.
  • the actual pressing force PK IST is the rigid or sliding average of several individual pressing forces at the stamp stations of the press.
  • the first input to the first control circuit R1 is the value of Preßkraftabweichung ⁇ PK between the target pressing force PK SOLL and the actual pressing force PK IST.
  • the control circuit R1 is acted upon by a second input variable, which is formed by the sensitivity of the pressing force dosing dPK / dD.
  • the sensitivity dPK / dD determines the accuracy of the pressing force control as a function of the change in dosage ⁇ D and is adjusted to the control during operation of the press, ie the sensitivity dPK / dD
  • the weight G, the height T and the hardness H of the tablets are measured continuously and a moving average is calculated.
  • a new value for the SET pressing force PK SOLL is calculated in the second control circuit R2, which in turn generates a dosage change ⁇ D in the first control circuit R1, whereby the weight deviation ⁇ G is compensated.
  • the variation of the target pressing force PK SOLL is determined by the value ⁇ PK SOLL.
  • a sensitivity weight dG / dPK is applied as the second input variable, which determines the accuracy of the weight control as a function of the change in pressing force ⁇ PK SHOULD .
  • This sensitivity dG / dPK is also adaptive and is adapted to the regulation during the tablet production process.
  • a deviation between the SET pressing force web height PK SOLLST and the ACTUAL pressing force PK IST is corrected by adjusting the web height by the value ⁇ ST.
  • the second input variable on the fifth control circuit R5 is the sensitivity-compression force web height dPK / ie with adaptive properties.
  • control loops R1 and R5 work alternatively.
  • All control loops R1 to R5 work each continuously. By a preferably sliding Averaging the individual control variables current values are always available.
  • the Control loops R1 to R5 can also each in several sub-circles are divided, e.g. depending on Control deviation different characteristics exhibit.
  • the limit values for the pressing force PK, at whose Reached the press stopped and / or tablets sorted out are determined adaptively by the data measured during operation of the Relationship between the pressing force PK and the Weight G, height T and hardness H is determined. This determination can also be made on a stamp basis. With given limits for the weight G, the Height T and hardness H can be deduced from this connection determine the associated press force limits.
  • variables of the controller model are fuzzified, by being translated into linguistic variables e.g. Weight deviation, sensitivity-weight, Height deviation, etc.
  • This linguistic Variables are assigned terms, e.g. "low, medium, high ", these terms being blurred Represent quantities.
  • the terms get membership functions, with the help of which it is possible for any value the linguistic variable the degree of affiliation to determine the individual terms. For example, one Weight deviation of 5mg the condition "medium Deviation "to grade 0.2, the condition” high Deviation "to grade 0.7.
  • the variables are linked using FUZZY operators, such as "Minimum operator, maximum Operator, gamma operator "or the like.
  • Processing the fuzzy information takes place by means of production rules, through methods of the FUZZY inference are processed, e.g. MAX-MIN / MAX-PROD inference or FAM / inference and other.
  • the output variables which are now called “FUZZY values” are defuzzified, i.e. into the "sharp” "Dosage change” and "Web height change” manipulated variables converted.
  • a defuzzification method is preferably the area center of gravity applied, but also other methods such as maximum average method, Maximum gravity method and others are possible.
