Definitions
- the invention relates to a method for operating a bottling plant, which comprises at least one phase of the start-up of the bottling plant and a phase of the normal operation of the bottled bottling plant.
- the stated object is achieved by a method according to claim 1, wherein: the actual value of at least one characteristic of a proper operating condition parameter is measured; and in the startup phase, allowing a different deviation of the actual value from a desired value of the parameter than in the phase of normal operation.
- an allowable deviation of the actual value from the target value to the unstable operating conditions during startup of the system can be adjusted without changing the allowable deviation of the actual value from the desired value during normal operation or restricting the control in normal operation ,
- a magnitude greater deviation is allowed for the start-up phase than for the phase of normal operation.
- the deviation could be defined, for example, as a relative value based on the desired value or as an absolute value or as a value range with a permissible maximum value and a permissible minimum value.
- a time-longer deviation is allowed for the phase of the startup than for the phase of normal operation.
- the parameter could, for example, be averaged over a certain period of time and the averaged result of the measurement evaluated.
- a different setpoint value is specified for the startup phase than for the phase of normal operation.
- This can take into account the fact that acceleration phases or filling phases or the like occur during startup of the system, which result in increased power consumption or increased flow rates or the like. It can thus be considered a known dynamic behavior of the filling system during startup, without increasing the allowable deviation from the target value to an undesirable level, thereby affecting the accuracy of error detection.
- a deviation is allowed in the start-up phase, which is updated during startup on the basis of the measurement of the characteristic parameter and / or the measurement of at least one further characteristic of the proper operating condition parameter. As a result, the monitoring of the bottling plant can be continuously adapted to changing conditions.
- a deviation is allowed in the phase of the startup, which is updated during startup as a function of time, ie time-dependent. This is particularly advantageous if essentially known dynamic influences on the operating state are to be taken into account. For example, different standard programs associated with particular phases of startup may be applied. In these cases, the number of parameters to be measured and evaluated is minimal.
- a change from the startup phase to the normal operation phase is initiated manually. This allows additional monitoring by an operator. As a result, it can be avoided that an allowable deviation optimized for the start-up of the installation is also used for normal production operation, and thus that a parameter fluctuation that is too high for normal operation is not recognized.
- a change from the start-up phase to the normal operation phase is automatically initiated based on a change in the state of switching in the bottling plant, a function of time, or based on the measurement of at least one parameter characteristic of the proper operating state.
- an improper operating state is detected, in which case special: the production is stopped; or products that are affected by the improper operating state, are routed specifically out of a regular product stream.
- a defined operating state can be assigned to the measured parameter at any time.
- the filling system can be controlled and regulated according to the detected operating state. For example, a stop production command may be issued.
- the production of defective products can be avoided or damage to the filling plant by operating at an inappropriate parameter value.
- the affected products can be controlled and returned to the regular product flow if specified quality criteria are met.
- an extraordinary operating condition is determined, in which case in particular: Products which are affected by the extraordinary operating state are deliberately discharged from a regular product stream become; and / or the affected products.
- an operating state can be defined by an increased probability compared to the normal state for the occurrence of a faulty product quality. It is therefore possible, for example, to divert the affected products and check for defects without having to stop the filling plant. For example, a distinction can be made between a case in which only a reduced product quality is to be feared, but the likelihood of damage to the bottling plant is low.
- the number of necessary stops can be reduced if an allowable deviation is exceeded, in order to avoid that each stop causes additional parameter fluctuations for itself and thus undesirably prolongs the startup phase.
- the parameter is pressure, electrical power, electrical resistance, electrical conductivity, velocity, angular velocity, speed, acceleration, weight, concentration, temperature, or force.
- These parameters are particularly suitable for checking machine conditions. For example, it would be possible to capture several of the mentioned parameters at the same time and comparing their actual values with the respective permissible deviations in order to be able to ascertain a proper or incorrect operating state with greater certainty.
- the method further comprises a phase of shutdown of the bottling plant, wherein in the phase of shutdown, a different deviation of the actual value is permitted by a desired value of the parameter than in the phase of normal operation. Since more parameter variations also occur during shutdown of the bottling plant than during normal operation of the bottling plant, the use of a non-standard deviation of the actual value during shutdown can in principle produce the same beneficial effects as described with respect to the startup phase are.
- the magnitude of the deviation could be allowed for the phase of shutdown as well as for the phase of normal operation.
- the target value could be set differently for the phase of shutdown in the same advantageous manner from the desired value of normal operation.
- updating the allowable deviation for the phase of shutdown could be done in an analogous manner as described for the startup phase.
- the change from the phase of normal operation to the phase of shutdown could be initiated manually or automatically, as described with respect to the transition between the phase of startup and the phase of normal operation.
- an improper operating state and, optionally, an extraordinary operating state could also be defined for the shutdown phase.
- a different deviation of the actual value from a desired value of the characteristic parameter is then permitted than in the phase of the startup.
- a different deviation of the actual value from a desired value of the characteristic parameter is then permitted than in the phase of the startup.
- FIG. 1 A preferred embodiment of the invention is shown in the drawing.
- the single figure shows a schematic diagram with a characteristic system parameters and the assigned nominal values and permissible deviations during the phases of startup, normal operation and shutdown of the system.
- the figure shows the time profile of a setpoint value S and an actual value M of a parameter P which is characteristic of the monitoring of a proper operating state of a bottling plant and which could be, for example, an electrical power consumption, a pressure, a volumetric flow or the like.
- the representation here serves merely to clarify the method according to the invention and is not limited to a specific parameter P or a specific curve of the desired value S or of the actual value M.
- the actual value M can be both a single measured value of the parameter P and a measurement result calculated in a suitable manner.
- an example of an operation of the filling system begins with a first phase of the start-up 1 of the filling system at a time TO.
- the operation of the filling plant changes from the first phase of the startup 1 into a second phase of the normal operation 2 of the started-up bottling plant.
- This phase of comparatively stable production conditions lasts until a time 12 at which the operation of the bottling plant changes to a third phase of shutdown 3 of the bottling plant.
- the change between operating phases 1 to 3 can take place both manually and automatically, in particular also as a function of the measured parameter P.
- the first phase of startup 1 of the bottling plant is associated with a first desired value S1 of the parameter P, the second phase of normal operation 2 with a second desired value S2 of the parameter P and the third phase of shutdown 3 a third target value S3 of the parameter P.
- the target values S1 to S3 are given by way of example only as different constant values.
- the phases 1 to 3 shown in the figure could, for example, also be assigned a common, constant or temporally variable setpoint value S, which is indicated by dashed lines in the figure.
- the setpoint values S, S1 to S3 could follow any desired curve during the operation of the bottling plant.
- the setpoints S1 to S3 could also be updated at certain intervals. The differentiation between individual setpoint values S1 to S3 merely serves for a better understanding of the described embodiment.
- the illustrated operating phases 1 to 3 are each assigned a permissible deviation of the actual value M from the desired value S1 to S3, the permissible deviation in the example in each case is defined by a permissible fluctuation range ⁇ 1 to ⁇ 3 of the actual value M, ie by the permissible value range of the parameter P, as well as by a period At1, ⁇ 2, ⁇ .3, within which the absolute value deviation ⁇ 1 to ⁇ 3 is considered or calculated.
- the permissible fluctuation range ⁇ 1 to ⁇ 3 thus corresponds to a permissible exceeding and / or undershooting of the assigned setpoint value S, S1 to S3.
- an improper operating state is defined by the fact that the actual value or measured value M must differ more than the permissible value from the setpoint value S1 to S3 at least over the time period At1, At2, A ⁇ 3 Deviation ⁇ 1 to ⁇ 3.
- the course of the actual value M would indicate an improper operating state, which could for example cause a stop of the machine.
- the actual value M varies slightly less than the allowable deviation ⁇ 1 in the first phase of the start-up 1 according to the waveform shown in solid lines. Accordingly, the solid curve of the actual value M in the first phase of start-up 1 would be characteristic for a proper operating state.
- the permissible fluctuation range ⁇ 1 to ⁇ 3 can be specified, for example, as a relative deviation from the setpoint value S, S1 to S3, as well as an absolute deviation or as a sign-independent deviation.
- the respective permissible exceeding and undershooting of at least one of the desired values S, S1 to S3 could also differ from one another.
- the permissible fluctuation range ⁇ 1 to ⁇ 3 from the setpoint value S, S1 to S3 can of course also be specified by a range of values between corresponding maximum values and minimum values of the actual value M.
- a smaller fluctuation range ⁇ 2 is permissible than in the first phase of start-up 1.
- the associated evaluation period A12 during which the actual value M must lie within the permissible fluctuation range ⁇ 2, is smaller than the evaluation period At1 of the first Phase of startup 1.
- Different evaluation periods At1, At2 would be useful, for example, if in the first phase of startup 1 a short-term fluctuation of the actual value M occurs, which is greater in magnitude than the permissible fluctuation range ⁇ 1 in the phase 1 of the startup. In this case, one would like to avoid that this short-term fluctuation of the actual value M leads to a false positive error message and is assigned to an incorrect operating state.
- the permissible deviation of the actual value M from the desired value S, S1 in the phase of startup 1 differs so that a dynamic behavior of the filling system is taken into account during startup and still reliable error detection in stable normal operation is possible.
- the permissible deviation for the startup phase 1 from the permissible deviation of the phase of normal operation 2 only by different evaluation periods At1, At2, only by different fluctuation widths ⁇ 1, ⁇ 2 or by a combination of different evaluation periods ⁇ 1, ⁇ 2 and different allowable fluctuation ranges ⁇ 1 , ⁇ 2 differ.
- This can also be achieved indirectly in that the setpoint values S1, S2 of the first and second phases differ and absolute threshold values for the actual value M remain unchanged or vary only slightly.
- the actual value M of the parameter P may be greater in magnitude than the permissible fluctuation range ⁇ 3, but an incorrect operating state does not necessarily have to be present if the actual Value M is shorter than the respectively assigned evaluation period, here ⁇ .3, beyond the permissible fluctuation range ⁇ 3.
- the permissible fluctuation range ⁇ 2 of the second phase of normal operation 2 is additionally shown. It would be possible to compare the actual value M in addition to the evaluation already described in the start-up phase 1 with the allowable fluctuation range ⁇ 2 of the second phase of the normal operation 2. For example, an extraordinary operating state could be defined for the cases in which the actual value M in the startup phase 1 remains within the allowable deviation ⁇ 1, ⁇ 1 of the first phase 1, but not within the allowable deviation ⁇ 2, At2 of the second phase second
- a particular parameter P could be particularly meaningful for a subsection of the individual phases 1 to 3, but in a particularly subsection of the same phases 1 to 3, be particularly strongly affected by operational fluctuations which are not caused by a malfunction.
- the allowable fluctuation range .DELTA. ⁇ 3 of the target value S3 during one of the illustrated phases 1 to 3 need not be constant but can be adjusted following any pattern.
- the allowable fluctuation width ⁇ 3 decreases continuously and linearly during the third phase of shutdown 3.
- the allowable deviations could be adjusted based on the measurement of other parameters characteristic of the proper operating condition.
- This adaptation can affect both the evaluation period At1 to At3 and the allowable fluctuation range ⁇ 1 to ⁇ 3. It would thus be possible to dynamically adapt the allowable deviation of the actual value from the target value S, S1 to S3 to changing operating conditions in order to increase the accuracy of the monitoring of the bottling plant and to reduce the occurrence of false positive monitoring results.
- the inventive method can be used for bottling plants and related production facilities, especially for individual treatment stations of these systems, for example in the beverage manufacturing industry or in pharmaceutical production.
- Particularly advantageous is the use in block-combined systems, for example in machine blocks comprising a blow molding machine, a labeling and filling machine, and optional packaging and palletizing machines, since in such complex systems, a large number of individual drive units must be supplied simultaneously and operated synchronously. In this case, for example, due to the masses to be moved simultaneously moments of inertia, which complicate the synchronization and monitoring of the individual characteristic parameters.
- the process of the invention can tailor the phase of plant start-up and the plant shutdown phase, in particular allowing for increased accuracy of monitoring and improved avoidance of false positive production interruptions.
