Definitions
- the invention relates to a method and a device to control a rotary tablet machine, being a rotor by a prime mover is rotatable, the rotor at least one Die with assigned upper stamps and lower stamps includes and one in the at least one Pressing force filled into the die is determined.
- Rotary tableting machines of the generic type Kind are known. It is typical that the rotor by starting the drive machine from standstill is brought up to its nominal speed. About at least the dies with the molding compound become a filling shoe filled and depending on the angular position of the rotor are sub-stamps and Upper punch axially displaced to the matrices.
- the lower and upper stamps are on at least one Press station, usually at a pre-press station and a main press station. There will be the upper and lower stamps on stationary Pressure rollers passed essentially tangentially, so that on the inserted in the matrices Press mass a pressing force can be applied.
- Matrices up to the press station i.e. up to the Pressure roller
- the invention is therefore based on the object Method and device of the generic type Way of creating, by means of which such damage is avoided can be.
- this object is achieved by a method solved with the features mentioned in claim 1. Because the determined pressing force with a predeterminable limit value is compared and if it falls below the setpoint speed of the rotor reduced to a speed below the nominal speed accelerating is advantageously possible of the rotor and accelerating the pressure rollers towards their nominal speeds in every operating situation synchronize. In particular, this avoids that the rotor in front of the pressure rollers on its Rated speed is accelerated. Thus a abrupt impact of the stamp on the pressure rollers and thus those existing in the prior art Possible damage to pressure rollers and / or stamp avoided.
- the object is further achieved by a Device for controlling a rotary tablet machine with the features mentioned in claim 8 solved.
- a control device or the like for control a drive machine of a rotor of the rotary tablet machine a facility for Determination of a pressing force and means for comparison the determined pressing force with a specifiable Pressing force and at least one means for specifying a target speed of the rotor depending on the Comparison of the determined pressing force with the specifiable one Pressing force is advantageously possible in a simple way a control function in the rotary tablet machine to implement that in Dependency of a degree of filling on matrices of the rotor controls a target speed of the rotor. This will in particular one adapted to the degree of filling of the matrices Starting up of the rotor possible, so that in particular mechanical loads / damage from Pressure rollers and / or press punches can be avoided can.
- Figure 1 shows a schematic partial view the handling of a rotor 12 with a total of 10 designated rotary tablet machine.
- the rotor 12 has a plurality of spaced apart around its circumference Matrices 14.
- Each die 14 is a lower stamp 16 and an upper stamp 18 assigned to the via the indicated guide curves 20 or 22 are performed.
- Rotor 12 and lower punch 16 and upper punch 18 rotate synchronously around the Rotation axis of the rotor 12.
- the rotor 12 is by a only indicated electric drive machine 24 here rotatable.
- the dies 14 is a filling device, a so-called filler shoe, only indicated here Pressed mass 26 filled.
- the rotary tablet machine 10 becomes the molding compound 26 filled over the entire height of the die 14.
- the fill level can, for example, by the Height of the lower stamp 16 on a not shown Stripping station can be defined.
- An example is an abnormal filling.
- the molding compound 26 is only part of the height filled into the matrices 14. It is also conceivable that into the matrices 14 - not for the one assumed here normal case - no molding compound 26 filled is. These conditions can occur, for example, when restarting the rotary tablet machine 10 after cleaning, maintenance or the like or after Interruption of the replenishment of the molding compound 26 via enter the filling device.
- the lower punches 16 and the upper punches 18 dip into the die 14 and compress the molding compound 26 to the desired tablet or the like.
- the lower punches 16 and the upper punches 18 are guided past at least one pressing station 28, which comprises stationary pressure rollers 30.
- the pressure rollers 30 are each rotatably supported about an axis of rotation 32. The distance between the pressure rollers 30 is defined and ultimately determines the height of the tablet to be pressed.
- the pressure rollers 30 are driven in the direction of the arrow 34 - the upper pressure roller 30 counterclockwise, the lower pressure roller 30 clockwise - by passing the lower punches 16 or upper punches 18 in accordance with the direction of movement 36 of the rotor 12.
- the lower punches 16 or upper punches 18 come in here System contact with the peripheral surface 38 of the pressure rollers 30 and thus set them in rotation, so to speak, by driving.
- the rotor 12 rotates at a speed n R
- the pressure rollers 30 rotate at a speed n D.
- the molding compound 26 to be pressed opposes the punches 16 and 18 in the pressing station 28 or in the region immediately preceding the pressing station 28 only with an insufficient counterforce.
- the pressure rollers 30 are in a manner known per se provided with sensors 40, by means of which the current pressing force PK is measured. Based on schematic representation in Figure 2, the invention further clarified.
- FIG. 2 shows that by the electric drive machine 24 drivable rotor 12 and the rotor 12 assigned pressure rollers 30. On the illustration the stamp was made for reasons of clarity waived.
- the rotary tablet machine 10 is a control unit 42 is assigned that a variety of Control functions can take over. Then only the essential for the invention Structure and function of control unit 42 described.
- the control device 42 is connected to the pressing force transducers 40 via a signal line 44 and receives a signal proportional to the actual pressing force PK IST pk IS .
- the control unit 42 is also connected to the electric drive machine 24 via a signal line 46, via which the electric drive machine 24 receives a control signal n R receives that corresponds to the target speed of the rotor 12 to be set.
- the control unit 42 includes a computing unit 48 which receives the signal pk IS and a signal provided by a storage means 50 pk SHOULD be supplied such that the desired pressing force PK SOLL corresponds to the pressure rollers 30.
- a step 52 the actual signals delivered by the press force transducers 40 pk ACTUAL and the desired signal supplied by the storage means 50 pk SHOULD processed.
- the signal pk SHOULD and the signal pk IS determined.
- This difference signal pk diff is signaled in a further step 54 pk border linked.
- the signal pk limit is also provided by the storage means 50, for example.
- the extent to which the signal can be determined can be variably determined, for example pk limit corresponding pressing force PK GRENZ can deviate from the target pressing force PK SOLL .
- This difference between the pressing force limit value and the pressing force target value can be, for example, 10% of the pressing force target value.
- step 54 If it is now determined in step 54 that the difference between the actual pressing force value and the desired pressing force value is greater than the difference between the desired pressing force value and the pressing force limit value, that is to say that the actual pressing force value falls below the pressing force limit value a signal n rsoll generated, which corresponds to a target speed n R of the rotor 12. This target speed is less than the nominal speed of the rotor 12 in normal operation.
- step 56 the signal corresponding to the target speed n rsoll with a signal corresponding to the actual speed of the rotor 12 n installs linked. The speed signal becomes corresponding to a deviation between the actual speed and the target speed of the rotor 12 n R generated and made available to the drive machine 24. This then accelerates the rotor 12 to the predetermined speed n R.
- the speed of the rotor 12 is controlled as a function of the pressing force. It is hereby achieved that if the pressing force PK is assumed to be lower than the desired pressing force PK SHOULD, the rotor 12 does not rotate at its nominal speed. In particular in the case explained that the dies 14 are not or only partially filled with molding compound 26, this means that the rotor 12 rotates at a predeterminable minimum speed n R. This prevents the lower punch 16 and upper punch 18 of a properly filled die 14 from already hitting the pressure rollers 30 at the nominal speed of the rotor 12 when the lower punch 16 and the upper punch 18 hit for the first time. The mechanical load at this time is thus considerably reduced.
- the solution according to the invention is also suitable for recognizing, when the rotor 12 rotates at the nominal speed, whether the degree of filling of the dies 14 decreases with the molding compound 26.
- the pressing force PK on the pressure rollers 30 drops due to the direct relationships.
- this decrease in the actual pressing force also leads to a reduction in the desired speed n R of the rotor 12.
- either a gradual or continuous reduction of the target speed n R may be provided.
- the target speed n R for example equal to a predeterminable minimum rotational speed n Rmin or in intermediate steps of the nominal speed n RNom to the minimum speed n Rmin be reduced.
