DESCRIPTION OF EXEMPLIFICATION OR EXEMPLIFICATIONS

[0074] FIG. 1A shows schematically the main components of an example of a rotary container manufacturing arrangement for manufacturing containers 130, such as bottles or cans or other such containers. FIG. 1A shows a rinsing arrangement or rinsing station 101, to which the containers are fed in the direction of travel as indicated by the arrow 131, by a first conveyor arrangement 103, which can be a linear conveyor or a combination of a linear conveyor and a star wheel. Downstream of the rinsing arrangement or rinsing station 101, in the direction of travel as indicated by the arrow 131, the rinsed containers 130 are transported to a filling machine 105 by a second conveyor arrangement 104 that is formed, for example, by one or more star wheels that introduce containers 130 into the filling machine 105.

[0075] The filling machine 105 shown is of a revolving or rotary design, with a rotor 105, which revolves around a central, vertical machine axis. The rotor 105 is designed to receive and hold the containers 130 for filling at a plurality of filling positions 113 located about the periphery of the rotor 105. At each of the filling positions 103 is located a filling arrangement 114 having at least one filling device, element, apparatus, or valve. The filling arrangements 114 are designed to introduce a predetermined volume of product into the interior of the containers 130 to a predetermined or desired level.

[0076] The filling arrangements 114 receive the product from a vessel 117. The vessel 117 is a component, for example, of the revolving rotor 105. The vessel 117 can be connected by use of a rotary coupling or a coupling that permits rotation. The vessel 117 is also connected to at least one external supply by a conduit or supply line. In the embodiment shown in FIG. 1A, there are two external supplies 123 and 124 connected to the vessel 117 by corresponding supply lines, conduits, or arrangements 121 and 122.

[0077] Downstream of the filling machine 105, in the direction of travel of the containers 130, there can be a container closing arrangement or closing station 106 which closes or caps the containers 130. The container closing arrangement or closing station 106 can be connected by a third conveyor arrangement 107 to a container labeling arrangement or labeling station 108. The third conveyor arrangement may be formed, for example, by a plurality of star wheels, or may also include a linear conveyor device.

[0078] In the illustrated embodiment, the container information adding arrangement or station 108 has at least one unit, device, or module, such as for applying labels to containers 130. In the embodiment shown, the information adding arrangement 108 is connected by a star wheel conveyor structure to three output conveyor arrangements: a first output conveyor arrangement 109, a second output conveyor arrangement 110, and a third output conveyor arrangement 111, all of which convey filled, closed, and labeled containers 130 to different locations.

[0079] The first output conveyor arrangement 109, in the embodiment shown, is designed to convey containers 130 that are filled with a first product. The second output conveyor arrangement 110, in the embodiment shown, is designed to convey containers 130 that are filled with a second product. The third output conveyor arrangement 111, in the embodiment shown, is designed to convey incorrect containers 130. To further explain, the container filling plant includes at least one container inspection or monitoring device that is designed to inspect or monitor the containers 130. If a container is detected that has an undesired characteristic, such as defects, insufficient fill level, and incorrect information, the incorrect containers are directed to the third output conveyor arrangement 111 for removal.

[0080] The container filling plant can be controlled by a central control arrangement 112, which could be, for example, computerized control system that monitors and controls the operation of the various stations and mechanisms of the container filling plant.

[0081] The present application is described hereinafter in connection with a container treatment machine. It is understood that this exemplification is an example of the use of the method according to the present application, and an example for a type of machine. The present application can, however, be transferred in general to any desired machines for the treatment or production of workpieces or to methods for the monitoring of a process for treating or producing workpieces.

[0082] Represented in FIG. 1, with the general reference number 1, in grossly schematic form, is a machine for container treatment. The container treatment machine can be, for example, a machine for filling the containers with a fluid filling product, a closing device for applying closures onto a container opening, a labeling machine for applying a label, a container printing machine for applying a printed image onto the container wall, etc.

[0083] The machine 1 comprises a rotor 2, which is driven such as to rotate about a vertical machine axis. The drive can be continuous or intermittent (i.e. pulsed). Provided on the outer circumferential side of the rotor 2 are treatment stations 3, at which the treatment of the containers takes place. The treatment stations 3 are in one possible exemplification distributed at uniform angular distances on the circumferential side about the rotor 2.

[0084] The containers are conveyed to the machine 1, for example standing upright, by an inlet star 1.1 at an inlet E, and positioned at a treatment station 3. Due to the rotation of the rotor 2, the container arranged at the treatment station 3 is transported further in the transport direction TR to a transport path TS. During this further transport, the treatment process is carried out. The treatment process can be, for example, a filling process, a labeling process, a closure process of the container, etc. This treatment process can comprise, for example, several part processes or treatment process steps; with the filling process, for example, filling steps with different volume flows of the filling product.

[0085] By use of the rotation of the rotor 2, the container is transported to the outlet A, and from there it is transported away by an outlet star 1.2.

[0086] Provided at the treatment stations 1 are the sensors 4, by which acoustic signals or oscillations propagating in a body, designated hereinafter in general as oscillations, are detected. The sensors can be, for example, microphones, in one possible exemplification directional microphones or also surface-borne sound sensors. The surface-borne sound sensors can be provided in one possible exemplification for the measuring of oscillations in the treatment station 3 or its components or functional units.

[0087] The sensors 4 can be provided in this situation such as to be moved with the rotor 2. In one possible exemplification, in each case a sensor 4 or a group of sensors 4 can be integrated into a treatment station 3, in order to be able to detect oscillations that occur during the process. In this situation, the sensor 4 can be provided, for example, in the proximity of a component or functional unit of the treatment station 3, at which the oscillations occur that are to be detected. The sensor 4 can in one possible exemplification be provided and configured in such a way that monitoring of a process can be carried out during the rotation of the rotor 2 and the ongoing transport of the container associated with this. In one possible exemplification, this process may be started after the handover of the container at the treatment station 3, such that the transfer of the container at the treatment station 3 is detected by the process monitoring. As an alternative it is possible that the process monitoring relates to the detection of the taking up of the container by a gripping or clamping device of the treatment station 3 and the period of time after the container handover (i.e. to the process for container treatment that follows on from the container handover).

[0088] Before discussing further the specific operation of the sensors, the use of the sensors, according to at least one possible exemplification, will be discussed. FIGS. 2, 3, 4, and 5 show, by way of example, a filling machine, or treatment stations of a filling machine, and the use of the method according to the present application with such a machine.

[0089] Sketched in FIG. 2, by way of example, is the filling process, with its individual part processes in the angle regions of the rotor run at which these part processes are carried out.

[0090] After the container has been delivered by way of the inlet star 1.1, in a first angle sector I the opening of the filling valve takes place, as the first part process. This opening can, for example, be an opening from the closed position of the valve body into an open position, in which the filling valve is completely opened. Next, in a further part process, in the angle sector II, the container is partially filled with filling product. This filling can be carried out, for example, with the maximum possible filling product volume flow through the filling valve (rapid filling).

[0091] An angle sector III connects to the angle sector II, in which the filling valve is brought into a partially closed position, i.e. the valve body is moved out of the open position into an intermediate position between the open position and the closed position. As a result, the volume flow can be choked by the filling valve and the container filled with a reduced volume flow input (slow filling), which is completed in the angle sector IV.

[0092] In the angle sector V, the valve body is then moved out of the partially closed position into the closed position, such that, in the angle sector VI, the filling valve is closed (i.e. no more filling product can flow into the container). Following this, the container is conveyed away by way of the outlet star 1.2.

[0093] This filling process can be monitored by the evaluation unit 6, as is explained in greater detail hereinafter by reference to FIGS. 3, 4, and 5. FIG. 3 shows the closed position of the filling valve 7, and therefore corresponds to the state of the filling valve 7 immediately or substantially immediately or generally after the container inlet, or the state of the filling valve 7 in the angle sector VI. FIG. 4 shows the completely open position of the filling valve 7, and therefore corresponds to the state of the filling valve 7 in the angle sector II. FIG. 5 shows the partially closed position of the filling valve 7, and therefore corresponds to the state of the filling valve 7 in the angle sector IV.

[0094] As can be seen from FIGS. 3, 4, and 5, provided in each case at the filling valves 7, which are provided at the respective treatment stations 3, is in each case at least one sensor 4 for detecting oscillations in the region of this filling valve 7. This sensor 4 is coupled to the evaluation unit 6 for the transfer of information. This evaluation unit 6 can be formed, for example, by the machine control unit, such as a control computer. By use of the sensor 4, it is possible to detect and evaluate, for example, acoustic signals or oscillations which are caused by the raising or pressing of the valve body at the valve seat, by the beginning or ending of the fluid flow through the filling valve, by the movement of the valve body, or by the flowing of the filling product through the filling valve. In one possible exemplification, in the completely open position (FIG. 4) of the filling valve, the intensity of the flow sound is detected, in order to be able to draw conclusions from this with regard to the filling product volume flow flowing through the filling valve. In addition, in the partially closed position (FIG. 5), it can be detected whether the intensity of the flow sound has changed as expected, and no mechanical oscillations or acoustic signals could be detected which indicate contact of the valve body at the valve seat.

[0095] FIG. 6 shows in several partial representations Xa to Xg the part processes during a filling process in a greater degree of detail. The part processes shown in the partial representations Xa to Xg are run through in this sequence during the transport of the container from the inlet to the rotor 2. The treatment station 3, at which the respective filling element is provided, comprises in the possible exemplification shown a plurality of sensors 4. In the possible exemplification shown, these is a first sensor 4a, which is provided in the region of the filling valve 7, and a second sensor 4b, which is provided in the region of a container fixing element 8. This container fixing element 8 can be formed, for example, by a neck ring gripper, which can comprise actively movable gripper elements, but also passive gripper elements. These first and second sensors 4a, 4b, can detect oscillations at different parts of the filling element, as a result of which the precision of the evaluation and the identification of errors and peculiarities can be decidedly increased.

[0096] Hereinafter it is explained on the basis of the single partial representation in Xa to Xg, which part processes of the filling process can be detected by the first and second sensors 4a, 4b. In the partial representation Xa, the handover of the container takes place to the container fixing element 8, such that oscillations caused by this can be detected. The filling valve 7 is closed in this situation, and the container contact element 9 is located at a distance from the container mouth. Due to the rotation of the rotor 2, it is possible, for example, for wind sounds in the region of the container mouth to be detected.

[0097] As can be seen in the partial representation Xb, next the container contact element 9 is brought in contact against the container mouth, wherein the sounds caused by this are detected by the sensors 4a, 4b. In addition, a pre-tensioning of the container can be carried out here, which likewise causes detectable oscillations.

[0098] According to the partial representation Xc, it is further possible for a pre-tensioning of the container or a flushing or multiple flushing of the container to take place, wherein the sounds and oscillation behavior incurred can be detected.

[0099] As can be seen from the partial representation Xd, there then follows the complete opening of the filling valve 7, wherein, for example, here it is the adjustment movement of the valve body, the flow sound of the filling product, and the flow back of the tensioning gas which can be detected.

[0100] Next, as shown in the partial representation Xe, the filling valve is closed (complete closure or partial closure), wherein, in turn, it is the adjustment movement of the valve body and the end or fading away of the flow sound or the fading away of the back-flowing tensioning gas which can be detected.

[0101] According to the partial representation Xf, this can then be followed by the release of the container, wherein the sound incurred by the release and possible subsequent dripping sounds can be detected by the sensors 4a, 4b.

[0102] According to the partial representation Xg, next the container contact element 9 is located at a distance from the container mouth. In this situation, the sounds are detected which are incurred by the movement of the container contact element 9 or the container fixing element 8, and when the container is removed from the container fixing element 8. It is likewise possible, after the movement of the container contact element 9 or the container fixing element 8, due to the rotation of the rotor 2, for a wind sound to be identified in the region of the container mouth.

[0103] FIG. 7 shows, by way of example, a closer or treatment stations 3 of a closer, and the application of the method according to the present application with such a machine.

[0104] The treatment stations 3 of a closer, which are likewise provided at a rotor which can be driven such as to circulate, comprise in an inherently known manner a container fixing device 20, by which the containers which are to be closed are held or fixed at the treatment station 3. The container fixing device 20 in the possible exemplification shown is formed by a container carrier 20.1, on which the containers stand upright on their container bases, and a container holder 20.2, which engages in the region of the container neck or the container mouth, such as a neck ring gripper. In addition, a closure mechanism is provided, by which a closure element is applied onto the container mouth. The closure mechanism can in one possible exemplification comprise a closure unit 21, which can be driven such as to rotate about a vertical axis, also designated as a tulip, by which a closure element (e.g. a screw closure cap) can be screwed onto the thread provided at the container mouth. As an alternative, the closure mechanism can be configured for the clamping securing of a closure element (e.g. crown corks).

[0105] FIG. 7 shows in several partial representations XIa to XIf several part processes of a closure process. The part processes shown in the partial representations XIa to XIf are, for example, run through in this sequence during the transport of the container from the inlet to the outlet of the rotor 2. The treatment station 3, at which the respective closure element is provided, comprises, in the possible exemplification shown, a plurality of sensors 4. In the possible exemplification shown, these are a first sensor 4a, which is provided in the region of the container carrier 20.1, a second sensor 4b, which is provided in the region of the container holder 20.2, and a third sensor 4c, which is provided in the region of the closure unit 21 or its drive. It is understood that more than the sensors referred to can be provided distributed at different positions at the processing station 3. By use of these first to third sensors 4a, 4b, 4c, oscillations can be detected at different locations of the treatment station 3, as a result of which the precision of the evaluation and identification of errors or peculiarities can be decisively increased.

[0106] It will be explained hereinafter, on the basis of the individual partial representation in XIa to XIf, which part processes of the closure process can be detected by the sensors 4a, 4b, and 4c. In the part process according to the partial representation XIa, first the container is conveyed to the handling station and the closure element is received in the closure unit 21. In this situation, for example, sounds and oscillations caused by the container being delivered, or by the placement of the closure element, are detected by the sensors 4a, 4b, and 4c. Likewise, wind sounds caused by the rotating treatment station 2, such as wind sounds at the open container mouth of the filled container, are also detected.

[0107] In the part process shown in the partial representation XIb, the closure unit 21 is lowered, as indicated by the arrow, such that the closure element received in the closure unit 21, comes in contact against the container mouth. In this situation, for example sounds or oscillations caused by the lowering of the closure unit 21 can be detected by the sensors 4a, 4b, and 4c.

[0108] In the part process according to the partial representation XIc, the closure unit 21 is set in rotation in order to screw the closure element onto the thread. This screwing process can take place in several steps. For example, in a first step the closure element is screwed on with a higher revolution speed, and in a subsequent second step at a lower revolution speed. In the process step shown in the partial representation XIc, this is, for example, a screwing process with a higher revolution speed (in comparison with the process step according to the partial representation XId), as is indicated by the curved double arrow. As a result, the closure element can be screwed on rapidly, until the upper, inner closure element surface comes in contact at the container mouth. In this situation, for example, the sounds and oscillations caused by rotation of the closure unit 21, the drive of this closure unit 21, or the rubbing of the closure element at the thread, can be detected by the sensors 4a, 4b, and 4c.

[0109] In the part process according to the partial representation XId, a rotation of the closure unit 21 then takes place at reduced revolution speed (in comparison with the process step according to the partial representation XIc), as a result of which the closure element is tightened on the container thread. In this situation, for example, sounds and oscillations caused by the rotation of the closure unit 21, the drive of this closure unit 21, the rubbing of the closure element on the thread, or by the rubbing of the closure unit 21 against the closure element, are detected by the sensors 4a, 4b, and 4c.

[0110] This is followed by the raising of the closure unit 21, as shown in the partial representation XIe. In this situation, the sounds and oscillations caused by the movement of the closure unit 21 are detected by the sensors 4a, 4b, and 4c.

[0111] After the raising of the closure unit 21, for example, wind sounds from the closed container due to the further rotation of the rotor 2, or sounds caused by the releasing of the container from the treatment station 2 can be detected (partial representation XIf).

[0112] Due to the distribution of several sensors at different positions in the treatment station 2, the sounds and oscillations which occur at different locations can be better detected and assigned more precisely or substantially more precisely to the respective functional elements of the treatment station 2.

[0113] In at least one possible exemplification, with this method and the method variants referred to, reference signals and the measurement signals relating to them in each case are detected by the respective sensor of the treatment stations all or some at the same location or in the same angle region of the device. Accordingly, in at least one possible exemplification, the reference signals are detected from the patterns from different treatment stations or their function elements, which are also detected at different time spans (i.e. staggered times).

[0114] As has already been indicated heretofore, and is common to the at least one possible exemplification, due to the same or essentially the same process steps being carried out at the respective treatment stations 3, it can be assumed that processing stations 3 which do not exhibit any errors or peculiarities will deliver the same or essentially the same measurement signals to the respective sensors. As a result, an adjustment can be made of the measurement signals from the different treatment stations 3, and errors or peculiarities can be identified in that the measurement signals from one treatment station show significant deviations in relation to the measurement signals from the other treatment stations 3. In one possible exemplification, an averaging of the measurement signals from the treatment stations 3 can be carried out, and, for the evaluation of a current measurement signal, a comparison made between this current measurement signal and the mean value of measurements signals received previously. In this situation, with this mean value formation, in one possible exemplification, the measurement signals can be excluded which show features indicative of errors or peculiarities.

[0115] It is likewise conceivable that all or substantially all or some the sensors of a treatment station 3 can be adjusted relative to one another by a comparison of their measurement signals.

[0116] The design and function of the sensors 4 will now be discussed in greater detail in accordance with one possible exemplification. The sensor 4 can be configured in one possible exemplification for detecting measurement signals in the time range. In one possible exemplification, the sensor 4 can provide a time-changeable electrical output signal, which is dependent on the oscillations detected by the sensor 4. The output signals provided by the sensor 4 can be analyzed in an evaluation unit 6, either directly or after further signal processing, in order to determine whether the process that is to be monitored is running within predetermined tolerance values, or whether the detected signals exhibit peculiarities that are indicative of an error or signs of wear, and therefore proactive maintenance or repair are necessary and/or desired or process parameters must or should be changed, for example travel paths of a functional unit.

[0117] A shown in FIG. 1, the evaluation unit 6 can be provided as a central evaluation unit (i.e. the sensors 4 are coupled to the evaluation unit 6 by use of the data line) represented by a dotted line (represented by way of example), and this unit carries out the analysis and evaluation of the signals provided by the sensors 4. As an alternative, it is also conceivable that the evaluation is carried out by a plurality of evaluation modules, and in each case groups of sensors 4 are formed, wherein each group of sensors 4 is coupled to a specific evaluation module. With such an arrangement it is also possible for a superordinated evaluation unit to be provided, to which the evaluation information provided by the evaluation modules is conveyed, and evaluated for the entire machine. In one possible exemplification, the arrangement of evaluation modules and a superordinated evaluation unit can form a master-slave structure for the evaluation of the signals.

[0118] In operation, a plurality of signal spectra (signal amplitude over the frequency), can be obtained, for example, by a transformation of the time-dependent signals provided by a sensor 4 into the frequency range. The transformation can take place, for example, by use of a Fast-Fourier Transformation (FFT).

[0119] For example, at a first frequency, a dominating spectrum portion results, for example, from a periodic and time-discrete occurring process step (e.g. closure movement of valve, delivery of closure element, etc.). The first frequency can in this situation, for example, be dependent on the revolution speed of the rotor 2. Ancillary spectrum portions outside of the dominant spectrum portion represent, for example, interfering spectrum portions, which result from procedures at the container treatment machine 1 that produce other acoustic signals.

[0120] By way of example, a tolerance window can be established, in which a frequency range and an amplitude range are defined for the dominating spectral portion. In the situation in which the frequency and amplitude of the dominating spectral portion is located inside the tolerance window, the process step is recognized as error-free or an without peculiarities (i.e. no information indicative of a fault is being generated by the evaluation unit 6), or a proposal for a change of a process parameter (reduction of valve lift, change in closure speed of the valve, etc.). In the situation in which the amplitude of the spectrum portion resulting from the transfer of the holding and centering unit 2 falling short or exceeding the amplitude range specified by the tolerance window, and/or the frequency of this spectral portion lying outside the frequency range determined by the tolerance window, this is recognized as errored or with peculiarity, and therefore information indicative of a fault is generated, or the changing of a process parameter is proposed. It is also conceivable that several tolerance windows are used, for example a first tolerance window in the range of a frequency that corresponds to the revolution speed of the rotor, and a second tolerance window in the range of a frequency that corresponds to the frequency of the periodically recurring process step that to be detected.

[0121] In other words, each process step or mechanical function generates an acoustic signal having characteristics, such as an amplitude (Hertz), frequency, and decibel level, which acoustic signal will be detectable as being the dominant or most noticeable acoustic signal outside of the other, ancillary, acoustic signals produced, such as other mechanical sounds not pertinent to the particular process step. For example, the dominant acoustic signal might be produced by the closing of a filling valve, while there may be acoustic signals in the background produced by other mechanical operations or functions that are not to be analyzed. When the process step or mechanical function is performed as intended, an acoustic signal will be produced having the desired characteristics, such as, for example, a certain amplitude, frequency, and decibel level. The monitoring system uses this acoustic signal as a model of sorts for comparison. A deviation from this acoustic signal may indicate a malfunction or improper operation of the corresponding device. In the case of a filling valve, it could indicate incorrect timing of the closure or too hard of a closure or similar. It should be understood that some deviation from the ideal acoustic signal is acceptable, so a tolerance window can be established to determine acceptable deviations from the individual characteristics, such as the amplitude, frequency, and decibel level. In other words, ranges for the different characteristics of the acoustic signal for a particular process or function can be set, such that not all deviations from the ideal acoustic signal are detected as being errors or malfunctions. The tolerance window or ranges can be set as desired to establish what level of deviation, such as high, medium, or low, for example, constitutes an undesired condition or error condition indicating a malfunction.

[0122] The evaluation unit 6 can be configured such as to specify or localize more precisely the reason for the error or the peculiarity. In one possible exemplification, the evaluation unit 6 can identify at which treatment station 3 the error or peculiarity has been shown. In addition, the evaluation unit 6 can be configured to detect which part process or process step of the process being carried out at the treatment station 3 has incurred the error or peculiarity. This can be done, for example, by analysis of the measurement signal from the sensor 4, for example in such a way that the frequency or frequency spectrum and/or the time characteristic of the measurement signal is evaluated, and therefore identifies a specific part process or process step. In addition or as an alternative, for example, part process or process step exhibiting the peculiarity or the fault can be identified by evaluating the time span between the handover of the container to the treatment station and the occurrence of the oscillation. As an alterative, the rotation angle can be detected, by which the treatment station 3 has been moved further by the rotor 2 since the handover of the container to this treatment station 3 (other reference points of time are possible). From this rotation angle it is likewise possible to identify the part process or process step exhibiting the peculiarity or error.

[0123] In addition or as an alternative it is possible for the measurement signals from several sensors 4 of the treatment station 3, which are arranged at different positions inside the treatment station 3, to be evaluated for the determination of the part process or the process step that has incurred the error or the peculiarity. By use of the different positions of the sensors 4 and the occurrence of oscillations at different positions in the respective treatment station 3, a localization can be carried out of the place of occurrence of the oscillations.

[0124] The evaluation unit 6 can be further configured so as to assign the peculiarity or error identified to a container that was being treated at the respective treatment station 3 at which the peculiarity is being shown. In this way, a peculiarity detected at a treatment station 3 can lead to a peculiarity at a container being treated at this treatment station 3, such as an inadequate filling level, erroneous labeling, or a defective closure. This peculiarity of the container can, as shown in FIG. 1, be identified in an inspection unit 5 that follows on from the outlet A in the transport direction TR. In one possible exemplification, the container information items detected in the inspection unit 5 are compared with the evaluation information items provided by the evaluation unit 6. In this situation it is possible, in one possible exemplification, for containers that have been identified by the evaluation unit 6 as defective or as exhibiting a peculiarity to be examined by the inspection unit 5, and specifically or generally so as to determine whether the inspection unit 5 also identifies an error or peculiarity involving the container. The inspection unit 5 can accordingly check, for example, the filling level in the container, the labeling, the closure, etc. Accordingly, the result from the evaluation unit 6 can be verified or corrected by the inspection unit 5. In the event that the inspection unit 5, unlike the evaluation unit 6, does not identify an error or peculiarity, it is then possible, if necessary and/or desired, for a reference signal for the decision taken in the evaluation unit 6 to be adjusted. In general, therefore, a dynamic adjustment can be carried out of the decision criteria adopted for the decision in respect of an error or a peculiarity in the evaluation unit 6, based on the information items detected by the inspection unit 5.

[0125] At the treatment stations 3 of the machine 1, in each case in one possible exemplification the same or essentially the same treatment process or production process is carried out. Accordingly, at the treatment stations 3, provided no errors or peculiarities occur in the process being carried out there, the sensors 4 of the respective treatment stations 3 will deliver identical or very similar measurement signals. For the identification of errors or peculiarities, the evaluation unit 6 can compare the measurement signals assigned to the respective treatment stations 3 with one another, and detect errors or peculiarities in that the measurement signals from one treatment station 3 show a significant deviation in relation to the measurement signals detected at the other treatment stations 3. In general, therefore, the detection of an error or a peculiarity can take place by comparison with one another of the measurement signals obtained at the respective treatment stations 3.

[0126] In at least one possible exemplification according to the present application, a reference signal that is drawn on for the purpose of evaluation is derived by averaging of the measurement signals provided by the sensors 4 of the treatment stations 3. This reference signal can, for example, be determined in advance, and deposited in a memory storage unit, such that, in the subsequent operation of the machine 1, the current measurement signals can be compared with the reference signal. In one possible exemplification, the reference signal is adjusted during the running of the machine continuously or intermittently, for example after specific time intervals, in order to be able to adjust the reference signal dynamically to the current circumstances. For example, the oscillations detected by the sensors 4 at the treatment stations 3 can exhibit a dependency on process parameters. For example, the oscillations may exhibit a temperature dependency, or may change with a variable process value (e.g. volume flow of the filling product). By the dynamic adjustment of the reference signal, this reference signal can be adjusted to these current process circumstances.

[0127] It is also possible for the reference signal to be dynamically adjusted on the basis of a measurement value of a sensor that is detecting a process parameter. For example, a temperature sensor can be provided in order to detect the ambient temperature, filling product temperature, etc., or a pressure sensor for detecting the pressure of the filling product, or, in general, a sensor for detecting a process parameter. Based on the information from the sensor that is detecting the process parameter, the reference signal can be adjusted. For example, it is also possible for a table of reference signals to be stored, which contains several reference signals or reference signal values that are dependent on the process parameter. The selection of the reference signal or reference signal value to be used can be made as a dependency of the process parameter detected.

[0128] According to one possible exemplification, an evaluation of a signal received from the sensor 5, or a signal derived therefrom, in the frequency range, can be performed. In this situation, a measurement signal obtained from the sensor 4 in the frequency range, and a reference signal, likewise in the frequency range, are delivered to a comparator. The reference signal can, for example, be a frequency spectrum of an acoustic signal, which occurs during the process run at the treatment station 3. This reference signal can, for example, be determined and stored when the container treatment machine 1 is taken into operation. The measurement signal and/or the reference signal can be unfiltered signals, or can be filtered by use of a suitable filter (e.g. bandpass filter). Next, the measurement signal is compared by the comparator with the reference signal. The comparator can in one possible exemplification be configured in such a way that any deviations between the measurement signal and the reference signal will be detected. In the event of an adequate concordance between the measurement signal and the reference signal, an error-free process run, or process run without peculiarities will be identified. Otherwise, an error message can be generated. The comparator can be a constituent part of a central evaluation unit, or can be provided decentralized in the region of the respective sensors. For example, in the respective treatment station 3, next to the sensor 4, an evaluation module (comprising, among other elements, the comparator) can also be provided, in which, for example, the reference signal is stored, or which has access to a memory storage unit, in which the reference signal is deposited. It is also possible, for example, for the comparison of the measurement signal with the reference signal to take place in this evaluation module. This evaluation module can then communicate with a superordinated evaluation unit 6.

[0129] In another possible exemplification, an evaluation of a signal provided by a sensor 4, or a signal derived from that, in the time range, can also be performed. As input signals, a measurement signal and a reference signal are provided in the time range. The reference signal can be, for example, a measured time characteristic of an acoustic signal, which occurs during the process run at the treatment station 3. This reference signal can, for example, be determined and stored when the container treatment machine 1 is taken into operation. Next, the measurement signal provided by a sensor 4 and the reference signal are filtered by use of a filter, in one possible exemplification a band filter. By use of this it is possible, for example, for interfering fundamental components or background noises to be filtered out. The filtered measurement signal and the filtered reference signal are then passed to the comparator. The comparator can in one possible exemplification be configured in such a way that any deviations between the filtered measurement signal and the filtered reference signal will be detected. In the event of an adequate concordance between the measurement signal and the reference signal, an error-free process run, or process run without peculiarities will be identified. Otherwise, an error message can be generated. The comparator can be a constituent part of a central evaluation unit, or can be provided decentralized in the region of the respective sensors. For example, in the respective treatment station 3, next to the sensor 4, an evaluation module (comprising, among other elements, the comparator) can also be provided, in which, for example, the reference signal is stored, and in which the comparison of the filtered measurement signal with the filtered reference signal takes place. This evaluation module can then communicate with a superordinated evaluation unit 6.

[0130] It is also conceivable for the measurement signal to be analyzed in time range as well as in the frequency range, and in each case to be subjected to a comparison with a reference signal or a check against a tolerance window.

[0131] As sensors, use is made, for example, of microphones, in one possible exemplification directional microphones, or also surface-borne sound sensors. These can in one possible exemplification be configured as screened against other sources of sounds.

[0132] In another possible exemplification, there is a method in which the reference value in the tolerance field correlates with the angular position of the rotor 2 or, respectively, the container stations 3 arranged at it. The angular position is the position of a portion of the rotor 2, such as the portion at which a container is held, on the circular path of movement or rotation of the rotor, as measured according to a 360 degree circle. For example, the point at which a container is transferred or handed over to the rotor 2 could be set as the zero degree position. This portion of the rotor 2 then must travel a full 360 degrees to return to the zero degree position. The angular position is therefore the location of this portion of the rotor 2 at a particular time and place along the path of rotation. For example, the 180 degree position would be the time or place at which the portion of the rotor 2 is located halfway along the circular path of movement. If a process step is to occur at the 180 degree position, the angular position can be used in conjunction with the acoustic monitoring to determine errors and faulty operation. This is possible, for example, during the conveying of a container from the inlet star 1.1 to the respective treatment station. In this situation, the point in time of the transfer of the container is known by way of the angle position, such that it is possible to record the signals at that point in time, as a result of which data quantities and times can be economized. The measurement signals at this point in time or at this location should then correlate with one another.

[0133] In addition to the signal strength, a signal bundling in the time tolerance window is also expected before and after the first point in time, which correlates with an angular position a of the respective treatment station 3, for example of the rotor 2. In this situation a certain time scatter or spread in the tolerance window is expected. For example, measurement values relating to handover procedures of the containers can be recorded at the transfer from the inlet star 1.1 to the treatment stations 3. In the event the inlet star 1.1 is not synchronized in operation with the rotor 2, measurement signals from transfer procedures which are caused by an inlet star 1.1 will be detected that are outside of the tolerance window and therefore could be considered to be not synchronous signals that show an erroneous operation condition. In the event the inlet star 1.1 is synchronized in operation with the rotor 2, measurement signals from transfer procedures which are caused by an inlet star 1.1 will be detected that are within the tolerance window and therefore could be considered to be synchronous signals that show a proper or acceptable or desired operation condition.

[0134] For example, if there is a large and impermissible time spread of the detected signals, this is evidence that the rotor 2 and the inlet star 1.1 must or should be adjusted with regard to synchronous running. In this situation it may be presumed that the measurement signals scattered above and below the permissible tolerance window are a consequence of the deficient synchronous running, and that there is not, in fact, a defect at the treatment stations themselves.

[0135] The present application has been described heretofore by way of possible exemplifications. It is understood that a large number of modifications or derivations are possible without thereby departing from the underlying possible concept of the present application.
