Definitions
- the invention relates to a method for monitoring a manufacturing process of a synthetic thread according to the preamble of claim 1.
- Another object of the invention is to minimize the amount of instruction required of an operator to control multiple processing locations.
- an error graph is preferably to be understood as a measurement signal profile C, "snapshot") of the thread tension in which the measurement signal for the thread tension falls below or exceeds a predetermined limit value threshold and/or in which the measurement signal for the thread tension has a limits defined range (limit value violation). It has proven to be advantageous if an error graph is limited in time, for example at most 20 seconds, preferably at most 10 seconds. It has also proven to be advantageous if the time of the limit violation is temporal Seen roughly in the middle of an error graph.
- the invention was also not obvious from DE 4329 136 A1 due to the known method for controlling a thread tension on a false-twisting device.
- the frequency of abnormal thread tension thread states he summarizes. Although the frequency of a thread tension error can thus be registered, this does not contain any indication of a possible cause of the error. However, no error cause can be derived from an error frequency.
- the invention has the particular advantage that a distinction can be made between the causes of errors in order to determine the influence of the respective source of interference on the manufacturing development process and to assess the quality of the thread.
- the occurrence within a time window can be registered as an error frequency of the error cause.
- the error frequency of the respective error cause can thus be used as a parameter to initiate a differentiated intervention to eliminate the error.
- the variant of the method is particularly advantageous in which a permissible frequency limit value is assigned to the interference frequencies of each of the causes of errors. It is thus possible to take into account the occurrence of critical fault causes and the occurrence of less critical fault causes with different weightings when intervening in the manufacturing process. If the thread breaks, immediate intervention in the manufacturing process is certainly necessary. But not if a component is dirty or worn.
- the frequency limit of the fault frequency of one of the error causes includes a number of error causes that are considered permissible in the manufacturing process.
- the frequency limit can be determined from the number of occurrences alone, in order to enable targeted interventions in the manufacturing process.
- the variant of the method in which the frequency limit value of the fault frequency of one of the error causes relates to a period of time and/or a processing point.
- the frequency limit value of the fault frequency of one of the error causes relates to a period of time and/or a processing point.
- the running time of the template coil could be selected as a time segment in order to evaluate the causes of errors occurring therein in terms of their frequency of interference.
- the threads it is customary for the threads to be guided individually in parallel next to one another in a large number of processing points, see above that the separation of the cause of the error in the processing points is also an advantage.
- a variant of the method in which a message is sent to a person when one of the frequency limit values for the frequency of malfunctions is exceeded. This ensures that the responsible person can intervene in the manufacturing process in a targeted manner.
- the development of the invention is particularly advantageous in which the error frequencies of the error causes are analyzed using algorithms based on statistical methods and machine learning methods to identify common sequences of interference counts and/or an anomaly of interference counts.
- This variant of the method has the particular advantage that conspicuous frequencies of error causes are automatically recognized by the system without having to define specified frequency limit values.
- Such machine learning systems are based on the fact that continuous learning takes place.
- the variant of the method is particularly advantageous in which the sequences of interference frequencies are reported to a person of a group of people and in which the sequences of interference frequencies are evaluated and evaluated by the person. This ensures both quick access to eliminate the cause of the error in the manufacturing process and feedback to the machine learning system.
- the development of the invention is provided in which in the manufacturing process several threads are guided and monitored in parallel in several processing points and in which the frequency of malfunctions of the causes of errors in correlated to the processing points to be analyzed.
- the quality of the individual processing points can also be derived from it.
- a maintenance person is responsible for the maintenance of the machine.
- a process staff oversees the adjustment of the machine.
- the raw material for the manufacturing process is provided by the operating personnel.
- a variant of the method is provided in which the causes of errors are assigned to one of several groups of people and in which, in the event of a limit value of the frequency of malfunctions being exceeded, the error cause in question or in the be notified in the event of the reporting of the sequences / anomaly in the frequency of disturbances. Since with can advantageously avoid time delays in eliminating causes of error.
- the error causes are assigned one of several control commands, which are activated if the error frequency limit of the respective error cause is exceeded or if the sequence / anomaly of the error frequency is reported.
- automated interventions in troubleshooting can be advantageously integrated into the manufacturing process.
- the invention has the particular advantage that, from the large number of causes of error in a manufacturing process, it is possible to weight which of the causes of error affects the quality of the manufacturing process and the quality of the thread. In particular with the large number of data on error graphs, a targeted and rapid intervention to eliminate the causes of errors is thus advantageously possible.
- the method according to the invention for monitoring the manufacturing process of a synthetic thread is explained in more detail below using an exemplary embodiment of a manufacturing process with reference to the accompanying figures.
- Fig. 1 shows schematically an embodiment of a processing point of a textile machine for the production of a synthetic crimped thread
- Fig. 2 shows schematically a flow chart for monitoring the manufacturing process according to the embodiment according to Fig. 1
- Fig. 3 shows schematically several error graphs, each with a measurement signal curve of the thread tension of different causes of error
- Fig 4 shows a schematic flow chart for monitoring the manufacturing process according to the exemplary embodiment according to FIG
- FIG. 1 is shown schematically an embodiment of a processing point ei ner textile machine, in this case a texturing machine for producing a ge crimped synthetic thread.
- a processing point ei ner textile machine in this case a texturing machine for producing a ge crimped synthetic thread.
- Such texturing machines have a large number of such processing points which are constructed identically. In that regard, only one of the processing points of a textile machine will be described in more detail at this point.
- the processing point 1 shows the processing point 1 and a winding point 2 of the textile machine.
- the processing point 1 has a gate 4, in which a template bobbin 5 and a reserve bobbin 6 are held.
- the template spool 5 supplies a thread 3, which leads to stretching and texturing in the processing station 1.
- the feed coil 5 is also referred to as a so-called POY coil, since it was previously produced in a melt spinning process and was wound with a freshly spun POY thread.
- a thread end of the template bobbin 5 is denagging with a Fa of the reserve bobbin 6 connected by a thread knot. This ensures that the thread 3 is continuously withdrawn after the feed bobbin 5 realized.
- the end of the thread of the reserve spool 6 is then connected to the beginning of the thread of a new template spool 5 .
- the deduction of the thread 3 from the supply coil 5 is done by a first delivery plant 7.1.
- the delivery mechanism 7.1 is driven by a drive 8.1.
- the delivery mechanism 7.1 is formed by a driven godet and a freely rotatable roller around which the thread is wrapped several times.
- a heating device 9, a cooling device 10 and a texturing unit 11 are arranged downstream of the delivery mechanism 7.1.
- the texturing unit 11 is preferably designed as a friction twist generator in order to create a false twist on the multifilament thread, which causes the individual filaments of the thread to curl.
- a second delivery system 7.2 is arranged after the texturing unit 11, which is driven by the drive 8.2.
- the delivery mechanism 7.2 is identical in construction to the first delivery mechanism 7.1, with the second delivery mechanism 7.2 being operated at a higher peripheral speed for stretching the thread. Inner half of the processing point 1, the synthetic thread 3 is thus textured and stretched at the same time.
- the delivery mechanism 7.3 is driven by the drive 8.3.
- the delivery mechanism 7.3 is designed as a so-called clamping delivery mechanism that has a driven shaft and a pressure roller.
- the thread 3 is guided in a nip on the circumference of the shaft.
- the winding unit 2 has a bobbin holder 13 which carries a bobbin 14 .
- the bobbin holder 13 is pivotable and can be operated manually or automatically to replace the bobbins 14 .
- the Spu lenhalter 13 is associated with a drive roller 15, which is driven by a roller drive 15.1.
- the winding unit 2 is assigned a traversing device 12 which has a drivable traversing thread guide.
- the traversing thread guide is driven in an oscillating manner via the traversing drive 12.1.
- the oscillating drive 12.1 and the roller drive 15.1 of the winding station 2 are designed as individual drives and are connected to a machine control unit 16.
- the drives 8.1, 8.2 and 8.3 of the delivery mechanisms 7.1, 7.2 and 7.3 and the texturing drive 11.1 of the texturing unit 11 of the processing point 1 are designed as individual drives and coupled to the machine control unit 16.
- a thread tension on the thread 3 is continuously measured at a measuring point between the delivery mechanism 7.2 and 7.3.
- the measuring point is shown in the position shown by way of example between the delivery mechanisms 7.2 and 7.3.
- the yarn tension is preferably also measured in the yarn path in front of the delivery mechanism 7.2.
- a sensor device 17 is provided, which has a thread tension sensor 17.1 and a measurement signal pick-up 17.2.
- the sensor device 17 is connected to a data analysis unit 18 .
- the data analysis unit 18 is coupled to a transmitter 19 which is connected to suitable reception systems using wired or wireless transmission technologies in order to transmit information and signals.
- the data analysis unit 18 has a number of software modules in order to analyze the measurement signals from the sensor device 17 and the data obtained therefrom for monitoring the manufacturing process.
- FIG. 2 shows a first scheme of the data analysis unit 18 in the form of a flowchart.
- a thread tension analysis module 20 is assigned to the sensor device.
- the thread tension analysis module 20 continuously records the measurement signals from the sensor device and generates so-called error graphs.
- the error graphs define an abnormal measurement signal course of the thread tension. Error graphs of this kind are always generated using data technology when the thread tension measured online in the manufacturing process leaves the range defined by specified limit values. If the thread tension moves significantly outside of the defined range, this affects the quality of the thread and thus the quality of the manufactured product. A large number of error graphs are thus generated by the thread tension analysis module 20 . However, the error graphs are based on a specific cause that influences the manufacturing process of the thread as a disturbance variable.
- a machine learning module 21 is provided in order to be able to assign the underlying error causes to the error graphs.
- the machine learning module 21 has algorithms to identify the causes of errors for the error patterns on the basis of statistical methods and machine learning methods. Such machine learning modules are suitable for determining the error causes behind the error graphs due to an intensive learning phase that has been carried out beforehand. This analysis is carried out continuously so that the corresponding error causes are generated from the supplied error graphs. In this way, a plurality of different error causes can be determined, which are registered in the error cause module 22 .
- the cause of the error is identified by the code letters FC in FIG. Through the continuous monitoring of the yarn tension and the continuously generated error graphs, the error causes are also continuously determined.
- a fault frequency module 23 is provided, in which the fault frequencies of the error causes are continuously determined.
- the error frequency here represents the sum of the error causes and is referred to as IFC.
- a frequency limit value is assigned to each cause of error in order to assess which error cause and which error frequency of the error cause requires intervention to eliminate the error.
- the frequency limit values determine the maximum permissible occurrence of the error cause within a period of time or within a processing point. These limit values, which are denoted by L, are stored in a comparison module 24 for each of the causes of the error. The frequency limit values of the fault frequencies are then compared with the fault frequencies recorded per time segment or per processing point.
- the frequency of faults has not yet reached and exceeded the limit value, the occurrence of the fault cause in question continues to be registered. If the frequency limit is exceeded, a message is sent via an output module 25 direction, an alarm or a control signal is generated and transmitted via the transmitter 19 to a person in a group of people or to the control unit.
- FIG. 3 shows some exemplary embodiments of typical error graphs and their error causes, the frequency of faults of which are characterized by predefined frequency limit values.
- the individual error graphs are denoted by the capital letters A, B, C, D, E and are shown with the specific measurement signal curve of the yarn tension.
- the error graph B shows a typical measurement signal curve in the event of a node overflow.
- the connection between the supply spool and the reserve spool is established via a thread knot, which becomes visible when the thread tension is measured.
- Such causes of error may occur once within a runtime of a template coil.
- the running time of the template coil could be 60 minutes.
- the error graph C signals as the cause of the error that the thread is guided outside the clamping gap between the pressure roller and the drive shaft in a clamping delivery system. This cause of error can have a very negative effect, especially when winding up the thread and when changing the bobbin.
- the error graph signals your error in the starting material of the template coil.
- titer fluctuations in the supply thread can have a negative impact on the measurement signal of the thread tension.
- Such causes of error are to be evaluated with lower weighting.
- the error graph E shows a measurement signal curve of the thread tension, which indicates a dirty guide surface of a cooling rail of the cooling device.
- Such causes of error usually occur very sporadically at first, so that intervention is only required if they accumulate within a short period of time.
- the frequency limit value relates to one of the processing points of the textile machine.
- the periods of time used as a basis for the frequency limit values are purely exemplary and not decisive for the process. It is essential here that, given the large number of error graphs and error causes, the error causes are identified, which significantly influence the quality of product manufacture.
- the method according to the invention can also be advantageously implemented in such a way that the occurrence of the fault frequencies of the error causes is analyzed directly, without observing frequency limit values.
- FIG. 4 a flowchart of an alternative embodiment of the data analysis unit 18 is shown schematically in FIG. 4 .
- the exemplary embodiment is essentially identical to the aforementioned exemplary embodiment according to FIG. 2, so that only the differences are explained at this point and otherwise reference is made to the aforementioned description.
- another machine learning module 26 is assigned to the error cause module 22 .
- the machine learning module 26 has algorithms which, on the basis of statistical methods and machine learning methods, carry out analyzes of the frequency of malfunctions in order to identify frequencies that are noticeably abnormal or sequences of frequency of malfunctions. Such sequences or anomalies in the frequency of malfunctions of a relevant cause of error are then used to display a person, preferably an operator, via the output module 25 so that he can evaluate and evaluate them.
- the cause of the error can be eliminated to ensure optimal quality in the manufacturing process.
- the experiences made by the operator are helpful in order to provide the machine learning module 26 with appropriate feedback.
- Such machine learning modules thus reach a stage in which it is highly probable that targeted control commands from intervention in the process are possible. Automated production monitoring is therefore possible.
