Definitions
- Single sorting device for sorting tablets system with such a single sorting device and with a tableting device and method for
- the invention relates to a single sorting device for tablets. Furthermore, the invention relates to a system with such a Einzelortortiervortechnik and with a tabletting device with a plurality of press dies. Finally, the invention relates to a method for checking the proper functioning of a Einzelortortiervortechnik for a tabletting device with press dies.
- tablets can be sorted out, which do not meet certain quality requirements due to errors in the production process. Tablets can also be removed from the production process by individual sorting for later examinations.
- Tablets can be produced with so-called tabletting machines.
- tabletting machines are pharmaceutical rotary presses.
- a rotary press is known for example from DE 10 2009 020 196.
- the rotary press has a rotary driven rotor.
- the rotor revolves in a substantially horizontal plane.
- the rotor carries a variety of stamp pairs.
- the stamp pairs each consist of an upper punch and a lower punch.
- tablet raw material is filled in the space between the upper punch and the lower punch.
- the stamps then arrive at least one pressure roller unit.
- the pressure roller unit is connected downstream in the circumferential direction of the rotor.
- the punches are pressed against each other with pressure. This compacts the material to form the tablet.
- the punches enter a removal station downstream in the circumferential direction of the rotor. In the removal station, the stamps move apart and the tablet is removed and removed.
- a tabletting machine may include one or more pressing stations.
- the tablets may be pre-pressed in a first pressing station and the pre-pressed tablets then finished pressed in a second pressing station.
- Several individual pressing stations or several groups of pressing stations for pre-pressing and final pressing can be arranged so that each individually presses tablets independently of the other stations or groups, so that several tablets can be produced simultaneously.
- the actual pressing force with which a tablet was pressed indicates the tablet weight and the reliability of the compression. It is also desirable to produce reliably pressed tablets of as identical weight as possible. An individual sorting therefore compares the actual pressing force with a permissible pressing force interval. Tablets pressed with a pressing force out of the interval are discarded from the single-sorter. Each independent pressing station or group of pressing stations is assigned a single sorting device.
- the sorting is done for example via a puff of air or a slider. Discarded tablets are directed into a first discharge channel. The remaining tablets are directed into a second discharge channel.
- the individual sorting device is supplied with a press force signal for this purpose.
- the press force signal comes from a tabletting machine and can be assigned to the tablet to be sorted.
- a test of the individual sorting device may be of interest, for example, when the single sorting device is put into operation, either at initial startup or when starting up for a new batch or at the beginning of a new production batch or batch. According to the prior art, this is done, for example:
- One stamp is removed and replaced by another.
- tablets pressed with the exchanged stamp are pressed with a pressing force outside the permissible press force interval.
- the tablets are pressed with a stamp characteristic of the stamp exchanged.
- the result of the individual sorting can then easily be checked for the correct function of the individual sorting.
- this method requires reinstatement of the normal post-test stamp and thus opening of the tabletting machine, this form of test operation can not be considered as a start-up test of subsequent normal operation.
- one of the existing stamp can be changed, for example by sticking an embossing element only in its embossed image.
- the embossing element can then be removed again without major intervention in the tableting machine after the test operation.
- the modified die does not normally result in press force signals outside the allowable press force interval.
- the press force interval can then be reduced so that the press force signals are outside the reduced press force interval. Or the device will be explicitly notified of the changed ram.
- the known methods for testing the correct function of individual sorting devices are either not integral, since they do not check the correct functioning of the sorting on the basis of the pressing force signal and the actual allowable pressing force interval, or are not suitable for start-up test since they undergo major interventions after test operation and before normal operation require the system.
- a single sorting device for sorting tablets according to claim 1 is presented.
- the tablets have been pressed by a tabletting machine with press dies.
- the individual sorting device is suitable for separating tablets, to which an unacceptable press force signal can be assigned, from tablets, to which a permissible lying press force signal can be assigned.
- Illegal press force signals are outside an approved press force interval.
- Permitted press force signals are within the permitted press force interval.
- the individual sorting device comprises a tablet feed, a press force signal input for receiving press force signals assignable to the supplied tablets, a programmable control unit and a memory.
- the individual sorting device is characterized in that a test control program is stored in the memory.
- the test control program is provided for programming / parameterizing the control unit for a test operation.
- the test operation comprises the application of press force signals from at least one of the press dies with offset.
- the application of individual press force signals with offset enables the individual sorting device to identify the tablets based on the press force signals, since the application leads to a press force signal outside the permissible interval.
- a system is also proposed with a tableting device having a plurality of press dies and at least one individual sorting device presented according to the invention.
- the test mode includes a storage of signals received and generated during the test operation. A report is generated using the stored signals at the end of the test operation.
- the test control program can be part of a normal operating program.
- the test mode may precede normal operation. This means that a normal operating program for normal operation can also be stored in the memory of the individual sorting device.
- the single-sorting device may dispense the discrete tablets to two tablet dispensers and comprise at least one detecting device.
- the detection device can be arranged on one of the tablet dispensers.
- the detection device may be suitable for detecting tablets dispensed there.
- the detection device is connected to the control unit and the control unit is designed to count a number of detected tablets.
- the target number can be determined by a number of press punches of the tabletting machine, a number of the press die loaded with the offset press force signal and a total number of tablets sorted during the test operation.
- the method in this case comprises producing tablets with the tabletting device and feeding the tablets and the tablets which can be assigned to the tablets. force signals to the single sorting device.
- the press force signals are subjected to offset at least one selected pressing station before comparison. Not all stamps are selected. An absolute value of the offset or offsets is selected so that the applied press force signals are outside the permitted press force interval.
- a number of tablets produced by the selected ram and a number of tablets sorted out are additionally determined. Then the determined numbers are compared. Then, for example, performing a normal operation subsequent to the check may be made dependent on the determined numbers being the same.
- the selected press dies can be manipulated in such a way that the tablets produced by means of the changed press dies have a stampable image which can be distinguished from an embossing pattern of the other produced tablets. Then, the method may further comprise controlling the embossed image of screened tablets.
- An absolute value of the offset may be greater than or equal to half of a press force difference between a press force upper limit of the approved press force interval and a lower press force limit of the permitted press force interval.
- the absolute value of the offset can be greater than or equal to the press force difference.
- FIG. 1 shows a first exemplary embodiment of the invention
- Figure 2 shows a second exemplary embodiment of the invention.
- FIG. 1 shows a first embodiment of an individual sorting device according to the invention.
- the individual sorting device is used for sorting tablets which have been pressed by a tableting machine with press dies.
- the tableting machine may comprise one or more independent pressing stations or groups of pressing stations, the like are arranged that each on its own tablets pressed independently of the other stations or groups, so that several tablets can be produced simultaneously.
- independent pressing station or pressing station group is advantageously a Einzelortortiervorraum available.
- the individual sorting device 10 comprises a tablet feed 20, a press force signal input 30 for receiving press force signals which can be assigned to the supplied tablets, a control unit 40 and a memory 50.
- the control unit 40 is for example a computer, a controller or a programmable control unit.
- the individual sorting device 10 is supplied with tablets via the tablet feed 20 and the tablets associated pressing force signals via the signal input 30.
- control unit 40 different stored in the memory 50 programs can be loaded. Then, sorting is performed based on the loaded program by the control unit 40 driving a sorting unit 60.
- the sorting unit 60 sorts the tablets in accordance with the control and outputs them to one of at least two existing tablet dispensers 70, 80, for example, in collection containers, not shown, or on conveyors.
- At least two programs are stored in the memory 50.
- One of the programs is for normal operation and one for test operation.
- the press force signals and a predetermined same press force interval are used by the control unit 40 to determine the respective activation of the sorting unit 60.
- press force signals are compared with the pressing force interval and tablets to press force signals outside the pressing force interval of tablets to press force signals within the pressing force interval are separated, in the test mode press force signals selected punch selected by the control unit 40 with an offset applied and then only with compared to the press force interval.
- the selected ram can be acted upon with different offsets.
- the offset can be positive.
- the correct sorting can be verified if an upper limit of the press force of the permitted pressing force interval is exceeded.
- the offset can also be negative.
- the correct sorting can be verified when falling below a lower pressing force limit of the approved pressing force interval.
- the absolute value of the offset is greater than or equal to a press force difference between the press force upper limit and the press bottom force limit. Then the total signal (the offset force signal) is safely outside the interval.
- the value of the offset is greater than or equal to half the press force difference.
- press force signals essentially correspond to the mean value of upper press force limit and lower press force limit.
- the lower offset thus leads to a total signal above the upper press force limit.
- the overall signal is not so large that a maximum pressing force is exceeded.
- the maximum pressing force is a pressing force limit, which leads to an interruption in operation, for example, for the protection of tools, the machine or people.
- the value of the offset is determined individually for each pressing station.
- the value of the offset may depend on a previously determined average of press force signals of the respective press station and one of the two press force limits. The press force signals of the selected stations are thus changed so that they represent a pressing force outside the allowable pressing force interval.
- the punches in the selected press dies may be changed in their embossed pattern so that tablets pressed by the selected press dies are distinguishable from the tablets pressed by other presser punches. This is possible, for example, by adhering a structured film, a piece of creping adhesive tape or a piece of transparent adhesive tape. Then it is additionally possible to check whether only the tablets pressed by the selected press dies have been sorted out. Since the change of the punch leads to a change in the pressing force, an individual determination of the offset is advantageous here.
- the individual sorting device 10 of the second embodiment additionally comprises a detection device 90.
- the detection device 90 may be, for example, a vision system, such as a light barrier, a light scanner or a camera system. This is shown by way of example in FIG.
- the detection device 90 is arranged on one of the two tablet dispensers 70, 80.
- the detection device 90 detects whether a tablet has been dispensed.
- the output of a tablet is signaled to the control unit 40.
- the control unit 40 counts the signals of the detecting device 90 and determines the total number of tablets dispensed at the tablet dispensing. When the test program starts up, the counter is set to zero.
- the control unit 40 integrates or counts in this embodiment, the number of received press force signals.
- the control unit 40 thus determines the number of tablets supplied.
- a further, not shown detection device may be arranged on the tablet feeder 20, by means of which the control unit 40 may determine the number of tablets supplied.
- the count for the number of tablets supplied is also set to zero.
- control unit 40 determines that there is no discrepancy between the number of tablets to be discarded and the number of tablets actually sorted out, the test mode in which the predetermined number of tablets has been fed can be followed directly by normal operation.
- control unit 40 determines that there is a discrepancy between the number of tablets to be discarded and the number of tablets actually sorted out, normal operation can be prevented.
- control unit 40 controls for each application with an offset, whether corresponding to a detector signal from a detection device in the Or whether a detector signal from a Detektiervornchtung in the tablet output for admissible tablets fails to receive. Then, in the event of non-receipt of an expected detector signal or reception of an unexpected detector signal, the control unit 40 can also check whether the correct tablets have been sorted out.
- the selected pressing dies can be changed with respect to their embossing pattern so that tablets pressed by the selected pressing dies can be automatically distinguished from the tablets pressed by other pressing dies by means of an image recognition device. This is possible, for example, by adhering a structured film, a piece of creping adhesive tape or a piece of transparent adhesive tape.
- the image recognition device may be placed on one of the two tablet dispensers 70, 80.
- the image recognition device can detect the embossed image and automatically detect whether the detected embossed image corresponds to a embossing image which the tablets dispensed on this tablet dispenser should have.
