Definitions

  • the invention relates to a method for monitoring a process on a machine and to a machine having such process monitoring.
  • rotary machines which have a rotating transport element (hereinafter also referred to as a rotor) on which a plurality of treatment stations are provided, each with at least one associated functional element, in order to act directly or indirectly on the workpiece or container.
  • a rotating transport element hereinafter also referred to as a rotor
  • treatment stations each with at least one associated functional element, in order to act directly or indirectly on the workpiece or container.
  • the treatment of a workpiece or even the production of the workpiece can be done per se, during the rotation of the transport element, so that the workpiece is transported simultaneously along a transport path.
  • the treatment stations and functional elements provided there preferably each have an identical or substantially identical structure and the processes carried out at the treatment stations are identical or substantially identical. Due to the staggered feeding or removal of the workpieces, the processes or process steps at the respective treatment stations are delayed in time or are in different stages of the same process or process step, so that, for example, a second treatment station following a first treatment station performs the same process as the first one Treatment station executes, but delayed in time to this. As a rule, the same process or process step of each treatment station takes place at the same location of the device, such as in a defined angular range of a rotating device.
  • the invention relates to a method for monitoring a process or process step on a machine having a transport element with a plurality of treatment stations.
  • the transport element can be, for example, a revolving driven rotor on which the processing stations are provided on the circumference.
  • the transport element can be formed by a self-contained, rail-like transport path, on which independently movable transport elements are provided.
  • the treatment stations each comprise at least one functional element, by means of which the workpiece is acted upon directly or indirectly, wherein by means of the treatment stations and / or their at least one functional element in each case a workpiece to be treated is conveyed during treatment on a transport path between an inlet and an outlet or the workpiece is changed at a treatment station at least on a portion of this transport path and / or manufactured or acted on this workpiece.
  • the treatment stations each have at least one sensor for receiving a vibration frequency and / or an acoustic signal, by means of which a pattern generated by the treatment or production process at the respective treatment station and during the transport of the workpiece at this treatment station is detected.
  • a pattern is to be understood below a pattern of a vibration and / or an acoustic signal or its physically measurable amplitude or strength and / or frequency / course over a preferably limited period of time.
  • the measurement signal provided by the sensor, measurement signal profile or a signal derived therefrom is subsequently evaluated and compared with a reference signal or reference signal range.
  • a reference signal range should always be understood as the reference signal.
  • the monitoring of the process preferably does not relate to the transfer process of a holding and centering unit that can be releasably fixed to the treatment station, by means of which a container is held and that of a container Rotor is passed to a subsequent further rotor.
  • the process monitoring relates, for example, to mechanical switching and setting processes as well as process steps that are started after the workpiece has been introduced into the treatment station, ie after the inlet, and finished before the workpiece is removed from the treatment station of the transport element.
  • the generated patterns are thereby at least partially caused by one or more functional elements that are not removed from the treatment station or introduced into it during the process to be monitored.
  • the process monitoring can extend over a plurality of transport elements (eg rotors) of the machine, but the process monitoring takes place in each case for process steps that take place between the inlet and the outlet of the respective transport element.
  • the main advantage of the method is that errors or abnormalities are recognized early in the process and thus high repair costs and machine downtime can be counteracted. Rather, proactive, predictive machine maintenance or repair can be initiated even if the process is still within tolerable process boundaries. It is also possible that an adjustment of process parameters takes place based on the measurement signals detected by the sensors, i. the process is controlled or modified depending on the measurement signals, so that, for example, the waste of treated containers can be reduced.
  • the pattern is detected in a time range in which the workpiece is moved at least a quarter, preferably at least half of the transport distance between the inlet and the outlet.
  • the pattern is produced at one or more functional elements provided at the treatment station and not removed from the treatment station during the entire process.
  • the functional elements that are the cause of the development of the acoustic or mechanical Vibrations are an integral part of the treatment station, ie they are not removed from it during the entire process.
  • acoustic or mechanical vibrations of functional elements of the respective treatment stations can be picked up by the sensors and used for process monitoring.
  • Such functional elements may, for example, be components of the treatment stations which act directly or indirectly on the workpieces or cause them to act, such as, for example, a milling head, a drill, a valve flap, a valve body, a drive unit, a holding tulip or closure tulip for a container, a closing tool, for example for a bottle cap or screw cap, sealed jaws and much more.
  • the pattern is formed at least by a change in position of a functional element or a part thereof.
  • this can be a raising or lowering of a functional element, for example a valve body or a closing tool.
  • the change in position of a functional element can be detected via the process monitoring.
  • the pattern comprises an oscillation frequency and / or an acoustic signal that arises due to the achievement of an at least temporary end position of the functional element or of a part thereof.
  • the pattern comprises a vibration frequency and / or an acoustic signal which arises during the spatial positional change of the functional element or of a part thereof. The change in position can be caused in particular by a translatory or a rotational movement of a functional element or a part thereof.
  • the process carried out on the transport element comprises a plurality of sub-processes, wherein the patterns generated in these sub-processes are determined by a single sensor or by a group provided at the respective treatment station several sensors are detected.
  • the sensors can be positioned at the treatment station or be distributed to different positions in the treatment station, that at different functional elements of the treatment station resulting vibrations can be detected in an improved manner.
  • identical process steps or identical sub-processes in certain areas of the transport path between the inlet and the outlet are performed at different treatment stations or be performed at different treatment stations between the inlet and the outlet with time offset to each other identical process steps or the same sub-processes.
  • the different sub-processes are at least partially performed at different rotational positions of a rotationally driven about a rotational axis transport element.
  • the rotational positions of the transport element are in particular at rotational positions in the region between the inlet and the outlet on this transport element.
  • the measurement signals are recorded simultaneously at two or more treatment stations.
  • a temporally overlapping process monitoring takes place at the treatment stations, with treatment stations or their functional elements being substantially identical in construction.
  • the reference signal is determined in advance based on a plurality of measuring signals recorded at different treatment stations, with a priority of time offset, which are also ideally of identical construction.
  • a reference signal is calculated from measurement signals of different treatment stations, for example by temporal and / or value-based averaging. This averaging can be done using weighting factors so that the measurement signals can be weighted relative to each other.
  • the similar processes carried out at the plurality of treatment stations generally lead to identical or very similar measurement signals at the sensors. This fact may be for the determination of the Reference signal or the evaluation of abnormalities having measurement signals can be used.
  • the treatment stations are no longer observed, whose measured values already have a drift, approximations or exceedances from the at least one reference value or value range.
  • This type of evaluation has the advantage that under variable production conditions, such as, for example, temperature changes, etc., the changes in the characteristic features are continuously taken into account and thus a process monitoring which is more independent of production conditions is made possible.
  • the reference signal is adjusted intermittently or continuously.
  • the adaptation of the reference signal takes place in that measuring signals of several treatment stations are respectively determined at different times and used to calculate the reference signal.
  • a "normal" temporal change of the measurement signals under different boundary conditions for example caused by load or temperature changes, different workpieces or workpiece fillings, can be included in the calculation of the reference signal and thus lead to an adaptation of the reference signal to this change in the boundary conditions.
  • a set of reference signals is stored, wherein the set of reference signals comprises a plurality of reference signals dependent on a process parameter.
  • the reference signal can be adapted by detecting a process parameter, for example by a sensor (temperature sensor, pressure sensor, etc.) receiving this process parameter, and selecting from the set of reference signals one or more reference signals which correlate with the determined process parameter.
  • the reference signal is generated in-situ, in particular by averaging the measurement signals or signals derived therefrom, wherein the measurement signals or the signals derived therefrom are detected at at least two different treatment stations by the sensors assigned to these treatment stations, in particular the measurement signals or the derived signals delayed by at least two different treatment stations detects the sensors associated with these treatment stations.
  • the measurement signal or the signal that is evaluated for errors is assigned to an angular segment, preferably a treatment station of the transport element and / or a workpiece.
  • the workpiece can subsequently be checked, for example by an inspection unit, in order to determine whether this workpiece has errors indicating abnormalities and thus the process error detection was correct or not.
  • a sub-process at a treatment station is inferred based on the measurement signal or based on the signal evaluated with regard to errors.
  • the measurement waveform, the frequency spectrum or the time profile of the measurement signal can be analyzed and it can be deduced based on which sub-process was erroneous or conspicuous.
  • the rotational position of the transport element or the local position of a treatment station can also be evaluated in order to detect at which angular position of the rotor or position of the treatment station the measurement signal indicative of errors or abnormalities has been obtained.
  • the evaluation is carried out based on measurement signals provided by a plurality of sensors of a treatment station or signals derived therefrom. Due to the distributed arrangement of a plurality of sensors at a treatment station (for example arranged on different functional elements), the recognition of which sub-process has exhibited the error or conspicuity can be decisively improved.
  • information obtained during the evaluation of the measurement signals or signals derived therefrom is compared with information from an inspection unit which subsequently checks the workpieces.
  • the inspection unit can thus be checked whether a workpiece that was detected by the evaluation as "faulty” or “conspicuous", even in the inspection performed by the inspection unit recognizable errors or abnormalities shows.

  • the reference signal is in the direction of a higher one Tolerance threshold can be adjusted.
  • the same also applies in the reverse manner, ie the evaluation of the measurement signals of the sensors provided at the processing stations has detected no error or conspicuousness, but the inspection unit was able to detect an error or a conspicuousness, so that the reference signal is adjusted in the direction of a lower tolerance threshold should be.
  • process parameters for the transport element and / or a treatment station are adapted and / or maintenance and service tasks are derived. For example, in the event that a sensor at a processing station of a capper receives a measurement signal which indicates a slip of the closure unit with respect to the closure element, the drive torque of the drive unit can be lowered. It is understood that a multiplicity of adaptation possibilities exist here depending on the detected measurement signal.
  • the measurement signal is compared with a reference signal.
  • the reference signal forms, for example, a good reference, i. represents a reference signal which is to be obtained in the case of a fault-free or without any abnormal process or process step.
  • the reference signal can be, for example, an amplitude and / or an amplitude characteristic or even a frequency and / or a frequency range of the measurement signal or a signal derived therefrom and recorded and stored after commissioning or regularly at the start of production of the machine.
  • a tolerance range is defined, which forms a desired range for the measurement signal. In the event that the measurement signal this target range leaves, an untypical process or process step can be deduced.
  • the tolerance range can in particular specify an amplitude range, frequency range, a temporal amplitude progression range of the measurement signal or a signal derived therefrom.
  • the reference signal and the tolerance range are ideally formed from a correlation with one or more parameters of the device or components of the device.
  • Such correlating parameters are, for example, the nominal incremental value, i. the angular position of the skin drive of the machine, time or time window in which a measuring signal, such as, for example, a frequency or sound of the type or strength, is expected, a dependence of the measuring signal on the angular velocity of the rotor, etc.
  • the correlation could take place in the time domain and the amplitude and phase difference between the transfer signals can be determined, whereby as a correlation method, for example, the cross-correlation can be used.
  • the measurement signal is compared in the time domain with a reference signal.
  • the time profile of the measurement signal can be compared with the desired state (shown by the reference signal).
  • longer lasting acoustic signals or a plurality of temporally consecutive acoustic signals e.g., multiple beats, chattering, etc.

  • the frequency domain in particular periodically recurring acoustic signals can be better detected.
  • the measurement signal is filtered before the comparison with the reference signal.
  • the filter may be a digital filter (eg FIR filter). This makes it possible that interfering frequency ranges or certain background noise or disturbing fundamental vibrations are filtered out and thus do not flow into the measurement signal analysis.
  • the signal profile and / or the signal amplitude of the measurement signal or of a signal derived therefrom are evaluated. Also, the spectral position of the measurement signal or a signal derived therefrom, ie its frequency can be evaluated. This can also draw conclusions about the causes of abnormality or irregularity.
