Definitions
- a blister packaging machine of conventional construction comprises a forming station in which a plurality of cup-shaped depressions are formed in a bottom foil consisting of plastic or aluminum, in each of which a product, for example, in a downstream filling station a pharmaceutical tablet is inserted.
- the bottom film is fed to a sealing station.
- a cover sheet is fed and placed on the bottom sheet. By heat within the sealing station, the cover sheet is sealed tightly to the bottom sheet, thereby enclosing the product in the cup-shaped recess.
- the forming station is operated intermittently and thus discontinuously.
- the sealing station can either also be operated intermittently, alternatively, it is also known to operate the sealing station continuously, wherein the transition from the cyclic operation of the molding station for continuous operation of the sealing station via known balancing devices.
- Document US 4875329 discloses a method for controlling a blister packaging machine having a plurality of synchronized work stations.
- the performance of a blister packaging machine depends essentially on the clock rate R, ie the number of cycles to be performed per minute.
- a timing curve of a corresponding power stroke is shown as a simplified, polygonal path-time diagram in Fig. 2, which will be briefly explained below.
- the cyclically operated molding station which is to be assumed as an example below, must perform various movements and processes or treatments.
- a 1st adjustment namely the closing movement of the mold plates.
- the closing path S V is predetermined in terms of production technology and the closing movement is carried out over a predetermined period T V1 until point 1 (see FIG. 2) is reached, in which the mold plates are closed and have reached their end position.
- the mold plates have then reached their treatment state in which, for example, a preheated plastic bottom film is cooled over a period of time T B , wherein in addition a formation of the cup-shaped depressions in the bottom film takes place in particular by means of compressed air or forming dies.
- T B a period of time
- the cooling or treatment of the bottom film is completed and it is followed by a 2.
- Verstellterrorism namely the opening movement of the mold plates, which in turn via the path S V (but in the opposite direction) over a period T V2 .
- the starting position is reached again.
- the opened mold plates can then be kept in a resting state for a period T R.
- the duration of the period T R of the idle state depends predominantly on influences outside the forming station and can be very short or even 0 in the favorable case.
- the further transport of the bottom sheet can be initiated and executed.
- the further transport of the bottom film begins when the mold plates have moved apart around the path S V / 2, ie for the further transport of the bottom film until the end of the cycle there is still a time span t Z1 and from the beginning of the next Clock until the time when the mold plates are half closed again, a period of time t Z2 available, wherein a total transport time Tz from the sum of t Z1 and t Z2 results.
- the curves were determined mechanically by rotating cams, the rotational movement of which were derived from a central, driven main shaft, the so-called royal wave.
- the curves are stored in software and the motor drive the adjustment movements via servo motors, which are addressed by an electronic control system or the corresponding software.
- the movement sections of the cycle curve are designed so that they meet the process requirements as well as possible while still running at the highest possible clock rate.
- the individual steps of the clock to be performed with high reliability and safety and it is a high efficiency, i. a high performance of the packaging machine can be achieved.
- the determined format-specific process data are stored. If the blister packaging machine is to process blisters of the same format again at a later time, the stored data are retrieved and the packaging machine is operated accordingly. This approach is based on the theoretical idea that the same blister format can always be optimally processed with the same, stored process parameters.
- the blister packaging machine does not match the original preset maximum clock rate R of, for example, 75 cycles per minute can be operated because the tablets have changed slightly in size and thus run slightly slower through the feed channels of the filling station. With undiminished clock speed, the proportion of blisters that are incompletely filled, would rise sharply. Also problems in other machines of the packaging line may require a reduction of the cycle rate.
- the invention has for its object to provide a method for controlling a blister packaging machine, in which the clock rate can be changed arbitrarily within predetermined limits in the production phase, without causing problems in the packaging process and in particular when forming the bottom foil or when sealing the cover sheet.
- the essential process parameters namely the duration T V1 of the 1st adjustment movement, the duration T B of the treatment state and the duration T V2 of the second adjustment movement can be kept within narrow limits, which are favorable for the process flow.
- it is provided to keep the said periods T V1 , T B and T V2 unchanged when entering a modified clock rate R V and thus to completely use the clock time difference ⁇ T to change the duration T R of the idle state.
- the clock curve is changed in a change in the clock rate, it may be the forming station of a blister packaging machine.
- the forming station has two relatively adjustable mold plates, between which a bottom foil is provided with cup-shaped receptacles. If the bottom sheet is plastic, it is processed in a preheated state and cooled in the forming station.
- the first adjustment is then formed by the closing movement of the mold plates, wherein the closing movement is completed only when reaching the end position of the mold plates and the mold plates can already be in abutment in the last movement phase of the closing movement.
- the mold plates remain for a period of time T B in a treatment state in which the bottom film is shaped and optionally cooled.
- the second adjustment movement is then the opening movement of the mold plates, which return to their opened starting position. Subsequently, the mold plates remain in their open position over a period T R. If the cycle time difference AT obtained by reducing the clock rate is fully used to change the duration T R of the resting state and the temperature of the preheated film remains unchanged, thus the actual treatment of the base film does not change in the forming station of the blister packaging machine and the mold plates are moved at the preset speed. A reduction in the clock rate merely results in the mold plates remaining in their open position for an extended period of time at the end of the cycle.
- the constant maintenance of the periods T V1 , T B and T V2 leads to keeping constant the process-relevant size of the forming time. In this way, a good deformation of the bottom foil is given at the same time high process reliability.
- the workstation ei ne sealing station with relatively adjustable sealing plates, between which a cover sheet is sealed onto the bottom foil.
- the 1st adjustment movement is the closing movement of the sealing plates, which remain at the end of the closing movement over the period T B in a treatment state in which the sealing of the cover film takes place on the bottom film.
- the 2nd adjustment is the opening movement of the sealing plates, the sealing plates remain after reaching their open position in this for the period T R.
- the keeping constant of the periods T V1 , T B and T V2 for keeping constant the process-relevant size of the sealing time.
- the changed clock rate R V to be entered does not assume any desired value and in particular can not become excessively small. It is therefore provided that a clock difference ⁇ R resulting from the preset clock rate R and the changed clock rate R V is limited to a limit value ⁇ R G.
- the threshold ⁇ R G may be in the range of 20% to 30% of the preset clock rate R and is preferably 25% of the preset clock rate R.
- Fig. 1 shows the essential components of a blister packaging machine 10 in a schematic representation.
- a plastic bottom sheet 11 coming from a supply is first fed to a heating station 12 which has a lower heating plate 12b and an upper heating plate 12a which is adjustable relative to the lower heating plate 12b.
- a heating station 12 which has a lower heating plate 12b and an upper heating plate 12a which is adjustable relative to the lower heating plate 12b.
- the two heating plates 12a and 12b are closed, the bottom sheet received therebetween is heated.
- a forming station 13 which comprises a lower mold plate 13a and an upper mold plate 13b which can be adjusted for this purpose.
- the two mold plates 13a and 13b which are shown in the open position, can be closed, wherein the recorded between the closed mold plates 13a and 13b Bottom film is cooled and at the same time provided by supplying compressed air or by means of dies with cup-shaped depressions.
- a transport device 14 connects, by means of which the bottom sheet 11 is cyclically pulled through the individual stations.
- the provided with the cup-like depressions bottom sheet 11 is then fed via pulleys 15 and 16 of a filling station 17, in which a product, such as a pharmaceutical tablet is inserted into each well.
- the bottom foil 11 then runs to a sealing station 20.
- a cover foil 18 is placed on the bottom foil 11 via a deflection roller 19.
- the sealing station 20 which includes a lower seal plate 20b and an upper seal plate 20a, the cover film 18 is sealed to the bottom film 11 by closing the warm seal plates 20a and 20b and applying the heat to the films.
- the sealing station 20 is followed by a further transport device 21, which is synchronized in its movement with the transport device 14 and provides for a cyclic transport of the given after the sealing station 20 film composite.
- Fig. 2 shows the already explained simplified path-time diagram of a clock curve, for example, the forming station 13.
- the thereby assumed maximum cycle time T max is 800 ms, which corresponds to a clock rate R of 75 cycles per minute.
- the treatment state is completed and it follows the opening of the mold plates 13a and 13b, which in turn takes place via the path S V in the reverse direction to the closing movement and over a period T V2 .
- the opened starting position of the mold plates 13a and 13b is again reached, in which they remain in a resting state for a period T R until the next cycle begins.
- the user may decrease the preset clock rate R.
- the input device 30 is associated with a processing unit 40, which determines the corresponding clock curve from the input value for the changed clock rate R V and in particular checks whether the input value of the clock rate is within predetermined limits.
