Description

[Technical field]

[0001] The present disclosure relates to an electronic device for locating a malfunction in the spinning and winding section of a spinning mill and a method for locating a malfunction in the spinning and winding section of a spinning mill.

[0002] Background technology A spinning mill includes various sections equipped with different types of textile machines for converting natural and synthetic fibers and their mixtures into yarns. A spinning mill is designed to produce yarns in a form that allows proper yarn performance in the subsequent production steps. For this purpose, it is required that the yarns meet certain quality parameters and that they are produced in a configuration that is adapted for the subsequent production steps. The quality parameters of the yarns may relate to mass, thickness, number of filaments, etc. The configuration of the yarns produced by the spinning mill may relate to the yarn bobbins on which large quantities of yarn are wound for efficient transport and use.

[0003] The spinning and winding section of a spinning mill may include one or more spinning machines and one or more winding machines.

[0004] The spinning machine includes a number of spinning stations, where roving bobbins are received from an upstream textile machine, where the roving is unwound from the roving bobbins, stretched, twisted (spun) and wound as yarn onto a tube forming a yarn supply bobbin, and yarn parameters can be monitored during the production of the yarn supply bobbins.

[0005] The winding machine is disposed downstream of the spinning machine and receives the yarn supply bobbins produced by the spinning machine.

[0006] The winding machine comprises a number of winding positions, where the yarn supply bobbins produced by the upstream spinning machine are sequentially rewound onto a cross-wound bobbin. The aim of the rewinding is to produce large yarn bobbins that can be efficiently transported and used. During the rewinding, the yarn properties can be monitored and compared with predefined quality criteria. If the quality criteria are not met, defective parts of the yarn can be removed. For this purpose, so-called yarn clearing systems are known (see for example WO 2012 / 051730, which enable respective clearing operations).

[0007] The yarn bobbins are produced by a winding machine in a configuration adapted for the subsequent manufacturing steps.

[0008] EP 3305700 A1 discloses a yarn winding system, which includes an automatic winder configured to wind a yarn from a yarn supply bobbin to form a package, and a roving frame and a spinning frame, each configured to perform a spinning process in a preceding step to the automatic winder. The automatic winder includes a yarn monitoring unit configured to detect a running state of the yarn, and a transmission unit configured to transmit information on the monitoring result of the yarn monitoring unit to the roving frame and the spinning frame. The roving frame and the spinning frame include a receiving unit configured to receive information on the monitoring result of the yarn monitoring unit from the automatic winder. The spinning frame winds the yarn to form a yarn supply bobbin. The automatic winder winds the yarn from the yarn supply bobbin to form a package. A bobbin transport device transports the yarn supply bobbins from the spinning frame to the automatic winder, and transports empty bobbins from the automatic winder to the spinning frame, with each tray including an RF (radio frequency) tag for storing information on the yarn supply bobbin. The bobbin transport device includes an RF writer for writing information to an RF tag including unit identification information for identifying the spinning unit that formed the yarn supplying bobbin and doffing information for identifying the timing of doffing. The automatic winder includes an RF reader for reading the information written in the RF tag in order to identify the spinning unit that formed the yarn supplying bobbin and the timing of doffing.

[0009] US 2021 / 148012 discloses a ring spinning system including a ring spinning machine with a plurality of spinning positions and a winding machine with a plurality of winding positions. The yarn is spun at one of the spinning positions and wound onto a cop. Values ​​of spinning parameters are determined at different times during winding of the cop and stored as spinning data. The cop is transported from the spinning position to one of the winding positions. At the winding position, the yarn is rewound from the cop onto a yarn bobbin. Values ​​of yarn parameters are determined at different times during rewinding of the cop and stored as yarn data. The spinning data and the yarn data are automatically assigned to each other such that they relate to the same yarn section. Based on the assigned spinning data and the yarn data, an intervention is performed in the ring spinning machine.

[0010] US 5,100,073 discloses an automatic textile winder. Each spinning tube fed to the winder has associated thereto an indication of origin, for example in the form of a label, marking or the like. A quality control device is provided at each winding station to monitor quality-related parameters of the yarn winding operation. Another device is provided at each winding station, which is associated with each quality control device to delete the indications of spinning tubes whose yarn meets a predefined value of a quality-related parameter determined by the quality control device, but leaves intact the indications of spinning tubes whose yarn does not meet such quality value. Each spinning tube discharged from the winding station is conveyed to a detection station for reading or otherwise detecting the indications remaining on the spinning tube. In this way the origin of inferior or poor quality yarns can be easily identified.

[0011] DE 10 2016 007 779 A1 relates to the monitoring of the correct operation of the spinning positions of a ring spinning frame. A device identifies the spinning cop and allows it to be assigned at any time to the spinning position which produced this spinning cop. A sensor device arranged at the winding position of a downstream automatic winder monitors the yarn of the spinning cop during the subsequent rewinding process. According to the invention, the running yarn of the spinning cop is scanned by a sensor device designed as a yarn tension sensor, the yarn tension data are sent to a winding unit computer, and yarn tension data exceeding a predeterminable limit value are determined, which indicates a tightly wound spinning cop, which is interpreted as problematic. The yarn tension data is then assigned to the spinning unit of the ring spinning frame which produced the spinning cop in question.

[0012] BRIEF SUMMARY OF THE INVETION An electronic device for locating a malfunction in the spinning and winding section of a spinning mill as well as a method for locating a malfunction in the spinning and winding section of a spinning mill may be required. An electronic device for locating a malfunction in the spinning machine or in the winding machine or in the transfer of yarn supply bobbins from the spinning machine to the winding machine in the spinning and winding section of a spinning mill may be required. An electronic device for locating a malfunction in the spinning machine or in the winding machine or in the transfer of yarn supply bobbins from the spinning machine to the winding machine in the spinning and winding section of a spinning mill may be required, which allows for a fast localization of the malfunction and provides for a higher flexibility for localizing the malfunction.

[0013] Such requirements may be met by the subject matter of the independent claims. Advantageous embodiments are set forth in the dependent claims.

[0014] One aspect of the invention relates to an electronic device for localizing a malfunction in a spinning and winding section of a spinning mill, the spinning and winding section including one or more spinning machines and one or more winding machines, the one or more spinning machines configured to produce a plurality of yarn supply bobbins with wound yarn, the one or more winding machines configured to receive yarn supply bobbins with wound yarn produced by the one or more spinning machines for production of the yarn bobbins, the electronic device configured to receive spinning parameters of the produced yarn supply bobbins from the one or more spinning machines and receive winding parameters related to the production of the yarn bobbins from the one or more winding machines, the electronic device configured to compare at least one winding parameter with a level defining a normal state of the at least one winding parameter in order to detect a winding abnormality, and in case of a winding abnormality, configured to determine at least one spinning parameter of the yarn supply bobbin received at the one or more winding machines and compare it with a level defining a normal state of the at least one spinning parameter in order to localize the malfunction in the spinning and winding section. Based on the winding anomalies detected in the winder, malfunctions in the spinning and winding section, including the spinning frame and the winding frame, can be localized. The spinning and winding parameters can be received via respective signal lines, via a wired or wireless computer network, etc. For example, a number of winding errors exceeding a predefined limit may indicate a malfunction in the spinning and winding section. The location of the malfunction is determined by comparing the spinning parameters with a level that defines a normal state. For example, in the case of an excessive number of winding errors, the spinning parameters can be used to determine whether the malfunction is located in the winder, or in the spinning frame, or in the transport of the yarn supply bobbins.For example, the winding parameters may indicate that there are no abnormalities other than an excessive number of winding errors, but the spinning parameters indicate that an abnormality of an excessive number of winding errors occurs when a yarn supply bobbin produced at a particular spinning position, where the spinning parameters such as the rotation speed may be at an abnormal level, is received at the winding machine, thereby locating that spinning position as a malfunction in the spinning and winding section. This simple example cannot be interpreted as limiting the scope of the claims, since a person skilled in the art can easily define various scenarios for locating a malfunction in the spinning and winding section based on the respective received spinning and winding parameters.

[0015] A yarn supply bobbin typically has the spun yarn wound on a suitable carrier, such as a spun yarn wound on a tube. The tube can be adapted to carry a relatively small amount of yarn. A yarn supply bobbin with a relatively limited amount of yarn wound on the carrier tube can be called a cop. However, according to one aspect of the invention, which can also be considered as an independent and inventive concept, the yarn supply bobbin can also relate to a relatively large traverse-wound bobbin, for example produced by a rotor spinning machine or an air jet spinning machine, where, upon receipt at the winding machine, the spun yarn of a single traverse-wound bobbin is rewound on each (traverse) yarn bobbin. This can be done, for example, to improve the quality of the yarn by utilizing a yarn cleaning device, a splicing device, etc. of the winding machine, which allows different applications, for example for subsequent dyeing of the yarn or for use in special weaving machines that require rapid removal of the yarn from the traverse package. Such rewinding can also be necessary to obtain bobbins with particularly high quality yarn.

[0016] In some embodiments, the malfunction is located at the spinning machine, or at the winding machine, or at the transport of the yarn supply bobbins from the spinning machine to the winding machine. The malfunction can be located at either the spinning machine, the winding machine, the transport, or the malfunction can be located at a combination of the spinning machine, the winding machine, and the transport.

[0017] In some embodiments, spinning parameters for a yarn supplying bobbin received at one or more winding machines are determined based on a yarn supplying bobbin identifier for the yarn supplying bobbin. During production of the yarn supplying bobbins, the spinning parameters are assigned to and stored with the yarn supplying bobbin identifier. When the yarn supplying bobbin is received at the winding machine, the spinning parameters are determined based on the yarn supplying bobbin identifier.

[0018] In some embodiments, the malfunction is located in the winding machine if the spinning parameters have a normal state, or in the transfer section of the yarn supply bobbin from the spinning machine to the winding machine, and in the spinning machine if the spinning parameters do not have a normal state. After an anomaly in the winding machine is detected, the malfunction can be located by evaluating the spinning parameters. For example, the spinning parameters may be related to a spinning position having a certain rotation speed. If this certain rotation speed has a normal level, the malfunction in the spinning and winding section may be located in the winding machine. If this certain rotation speed does not have a normal level, the malfunction may be located in the spinning machine having a spinning position having this certain rotation speed.

[0019] In some embodiments, the spinning parameters relate to imperfection index, hairiness, coefficient of variation of yarn mass, variation index of yarn diameter, number of thick places per unit length, number of thin places per unit length, number of periodic yarn defects per unit length, number of yarn count variations per unit length and / or number of foreign objects per unit length. Spinning parameters widely available in the spinning and winding section can be used for localization of malfunctions.

[0020] In some embodiments, the spinning parameters relate to one or more of the following: doffing time, spindle speed, ring traveler speed, number of yarn breaks per unit time, air temperature and air humidity. Spinning parameters that are widely available in the spinning and winding section can be used for localization of malfunctions.

[0021] In some embodiments, the winding parameters relate to one or more of the following: yarn tension, number of clearing operations, energy consumption, number of produced yarn bobbins per unit time, imperfection index and hairiness. Winding parameters that are widely available in the spinning and winding section can be used for localization of malfunctions.

[0022] In some embodiments, the electronic device is further configured to receive spinning and / or winding parameters by accessing a spinning machine controller and / or a winding machine controller, allowing the electronic device to be easily adapted to existing spinning and winding sections.

[0023] In some embodiments, locating the malfunction is based on one or more of a neural network algorithm and a fuzzy logic algorithm.A power tool can be used to locate the malfunction in the spinning and winding section.

[0024] In some embodiments, the electronic device is further configured to notify one or more of the spinning machine, the winding machine, the automated repair system, and a computer display of the malfunction location. The electronic device can support automatic, semi-automatic, or manual correction of the malfunction in the spinning and winding section. Notification of the location to the spinning machine and / or the winding machine, e.g., the respective controllers, can support automatic correction, e.g., by activation of the respective robots. Notification of the location of the malfunction to a computer display can support semi-automatic or manual correction.

[0025] In some embodiments, the electronic device further includes a signal line interface configured to receive the spinning parameters from the one or more spinning machines and the winding parameters from the one or more winding machines via the signal line. The electronic device can be located separately from and away from the spinning machine and the winding machine, respectively.

[0026] The invention also relates to a computer system configured to carry out the method defined hereinafter, the computer system comprising one or more computers, the one or more computers preferably comprising a graphical user interface. The computer may relate to a machine controller, a desktop computer, a notebook computer, a tablet computer, a smartphone etc. The graphical user interface may relate to a display, a touch screen, a display with a keyboard and a mouse etc. The computer system may include existing controllers of spinning and winding machines, existing controllers and / or computers of a spinning mill etc.

[0027] The invention also relates to a method for localizing a malfunction in a spinning and winding section of a spinning mill, the spinning and winding section comprising one or more spinning machines and one or more winding machines, the one or more spinning machines being configured to produce a plurality of yarn supply bobbins with wound yarn, the one or more winding machines being configured to receive the yarn supply bobbins with wound yarn produced by the one or more spinning machines for the production of the yarn bobbins, the method comprising the steps executed by an electronic device or a computer system, namely: receiving the produced yarn supply bobbins with wound yarn from the one or more spinning machines; The method includes the steps of receiving spinning parameters of a yarn bobbin, receiving winding parameters related to the production of the yarn bobbin from one or more winding machines, comparing the at least one winding parameter with a level defining a normal state of the at least one winding parameter in order to detect a winding abnormality, and in case of a winding abnormality, determining the at least one spinning parameter of a supplying yarn bobbin received at the one or more winding machines and comparing it with a level defining a normal state of the at least one spinning parameter in order to localize a malfunction in the spinning and winding section.

[0028] In some embodiments, the malfunction is located at the spinning machine, or at the winding machine, or at the transfer of the yarn supply bobbins from the spinning machine to the winding machine.

[0029] In some embodiments, the malfunction is located in the winding machine if the spinning parameters have a normal state, or in the transfer section of the yarn supply bobbin from the spinning machine to the winding machine, and is located in the spinning machine if the spinning parameters do not have a normal state.

[0030] In some embodiments, the localization of the dysfunction is based on one or more of a neural network algorithm and a fuzzy logic algorithm.

[0031] In some embodiments, the method further includes notifying one or more of the spinning machine, the winding machine, an automated repair system, and a computer display of the location of the malfunction.

[0032] The invention will be better understood with the aid of the description of an embodiment given as an example illustrated by the drawings. [Brief description of the drawings]

[0033] [Figure 1] FIG. 2 shows a schematic diagram of an electronic device for localizing malfunctions in an exemplary spinning and winding section of a spinning mill having spinning and winding machines. [Diagram 2] FIG. 1 shows a schematic diagram of an electronic device for locating malfunctions in an exemplary spinning and winding section of a spinning mill having multiple spinning machines and multiple winding machines. [Diagram 3] FIG. 2 shows a schematic diagram of possible method steps of a method for localizing a malfunction in the spinning and winding section of a spinning mill.

[0034] Detailed Description of the Invention The foregoing summary as well as the following detailed description of the preferred embodiments will be better understood when read in conjunction with the accompanying drawings, in which: For the purposes of illustrating the invention, embodiments in which like numerals represent like parts throughout the several views of the drawings are presently preferred, with it being understood that the invention is not limited to the specific methods and instrumentalities disclosed.

[0035] 1 shows a schematic diagram of an electronic device 10 for localizing malfunctions in an exemplary spinning and winding section 1 of a spinning mill, which is equipped with a spinning machine 5 and a winding machine 7. In a typical spinning mill, the spinning and winding section 1 includes a number of spinning machines and a number of winding machines (not shown in FIG. 1).

[0036] As shown in Fig. 1, a spinning machine 5 is arranged upstream of a winding machine 7. Correspondingly, the winding machine 7 is arranged downstream of the spinning machine 5. In a typical spinning and winding section of a spinning mill, there are several spinning machines and several winding machines.

[0037] The spinning machine 5 may relate to a ring spinning machine. However, in the context of the present application, the spinning machine 5 may also relate to another type of spinning machine that typically produces yarn sections of relatively limited length, which are then rewound by a winder to form a bobbin with a yarn of sufficient length. For example, the spinning machine 5 may be a pot spinning machine. However, as also described herein, according to variants of the invention, the spinning machine may also be a rotor spinning machine or an air jet spinning machine.

[0038] The spinning machine 5 receives the roving 4 produced by the upstream roving 3 (typically, several rovings are arranged) and produces a supply bobbin 6 (carrier) with the wound yarn. The spinning machine 5 includes several spinning positions 51, 52, 53. At each spinning position 51, 52, 53, a roving 41, 42, 43 is received. For example, the roving 41, 42, 43 may be arranged on a bobbin or another type of carrier, for example a container of a certain dimension. Each spinning position 51, 52, 53 includes a spinning unit 511, 521, 531. Each spinning unit 511, 521, 531 may include a drafting device and a twisting device, where the drafting device is configured to draft the roving and the twisting device is configured to spin the drafted roving into a spun yarn and to wind the spun yarn onto a supply bobbin. At each spinning position 51, 52, 53, a yarn supply bobbin 61, 62, 63 is produced, each with a specific amount of spun yarn wound thereon. Typically, at a specific time, the yarn supply bobbin 61, 62, 63 is doffed from the spinning position 51, 52, 53 for further processing.

[0039] The winding machine 7 receives the yarn supply bobbin 6 produced by the upstream spinning machine 5 (typically, multiple upstream spinning machines are arranged) and produces the yarn bobbin 8. The winding machine 7 includes multiple winding positions 71, 72. At each winding position 71, 72, a yarn supply bobbin 61, 65, 63, 68 is received. Each winding position includes a winding unit 711, 721. Each winding unit 711, 721 may include a winding device, a tensioning device, a yarn monitoring device, an upper yarn catcher, a lower yarn catcher, a splicing device, a clearing system for removing yarns that do not meet a predetermined quality standard, etc. At each winding position 71, 72, one or more yarn supply bobbins 61, 65, 63, 69 can be received. In the example shown in FIG. 1, two yarn supply bobbins 61, 65, 63, 68 are received at each winding position 71, 72. However, more or less yarn supply bobbins may be received at the winding positions of the winder. At each winding position 71, 72, yarn is unwound from a yarn supply bobbin 61, 65, 63, 68 and wound onto a yarn bobbin 81, 82. At a particular time, a yarn bobbin is unloaded from the winding position 71, 72 for a subsequent production step.

[0040] Typically, the number of spinning positions 51, 52, 53 of the spinning machine 5 and the number of winding positions 71, 72 of the winding machine 7 are large and significantly exceed the small number of spinning and winding positions shown diagrammatically in FIG.

[0041] As shown in Fig. 1, the spinning machine 5 includes a spinning controller 50 for controlling the operation of the spinning machine 5. The spinning controller 50 is connected to the control units 510, 520, 530 of the spinning units 511, 521, 531 arranged at the spinning positions 51, 52, 53 via a signal line 5s. The control units 510, 520, 530 receive control signals from the spinning controller 50 via the signal line 5s and control the operation of the spinning units 511, 521, 531 to produce yarn supply bobbins 61, 62, 63 of desired specifications from the roving yarns 41, 42, 43. The desired specifications of the yarn supply bobbins 61, 62, 63 may relate to yarn quality, yarn quantity, number of yarn supply bobbins 61, 62, 63 produced per unit time, etc. The control signals make it possible to adjust the operating parameters of the spinning units 511, 512, 513, for example the spindle speed, the drafting rate, the mode of movement of the ring bench and / or the spindle bench, the rotation speed of the spinning pot, the rotation speed of the driven spinning ring, the rotation speed of the controlled rotating spinning ring, the ring traveler speed, etc. The control signals can also be used to control auxiliary modules of the spinning machine. For example, the auxiliary modules can be a spindle monitor of the spinning machine or a service robot of the spinning machine. For example, the control signals can instruct the service robot to go to a certain spinning position and perform a more detailed analysis of the spinning position and / or to perform a certain maintenance operation (for example, replacing the ring traveler or cleaning the rollers of the drafting device). The control units 510, 520, 530 transmit the monitor signals to the spinning controller 50 via the signal line 5s.The monitor signals may relate to the spinning units 511, 521, 531 (e.g. signals related to spindle speed, ring traveler speed, drafting rate, etc.), the rovings 41, 42, 43 (e.g. signals related to the presence and / or amount of roving at a particular spinning position (e.g. spindle position of a ring frame), roving carrier identifier, etc.), the spun yarns at the spinning units 511, 521, 531 (e.g. signals related to yarn imperfection index, hairiness, etc.), the yarn supplying bobbins 61, 62, 63 (e.g. yarn supplying bobbin identifier, etc.), etc. The monitor signals may be based on signals generated by the respective sensors or may be derived from these signals. The monitor signals may relate to yarn supply bobbin identifier (see detailed description below), imperfection index, hairiness, spinning position, doffing time (time remaining until next doffing), spindle speed, number of yarn breaks per unit time, ring traveler speed, spinning pot rotational speed, driven spinning ring rotational speed, controlled rotating spinning ring rotational speed, number of yarn breaks per unit time, number of yarn breaks per unit yarn length, air temperature, air humidity, etc.

[0042] As shown in Fig. 1, the winding machine 7 includes a winding controller 70 for controlling the operation of the winding machine 7. The winding controller 70 is connected to the control units 710, 720 of the winding units 711, 721 located at the winding positions 71, 72 via a signal line 7s. The control units 710, 720 receive control signals from the winding controller 70 via the signal line 7s and control the operation of the winding units 711, 721 to produce yarn bobbins 81, 82 of desired specifications from the yarn supply bobbins 61, 65, 63, 68. The desired specifications of the yarn bobbins 81, 82 may relate to the amount of yarn per yarn bobbin 81, 82, the number of yarn bobbins 81, 82 produced per unit time, the amount of energy required to produce the yarn bobbins 81, 82, etc. The control signals make it possible to adjust the operating parameters of the winding units 711, 721, 731, such as the winding speed, the number of active winding positions, the power of the vacuum system, the number of active yarn supply bobbin (bobbin) preparation stations, etc. The control units 710, 720 transmit monitor signals to the winding controller 70 via the signal lines 7s. The monitor signals may relate to the winding units 711, 721, the yarn supply bobbins 61, 65, 63, 68, the yarn unwound from the yarn supply bobbins 61, 65, 63, 68 and wound onto the yarn bobbins 81, 82, the yarn bobbins 81, 82, etc. The monitor signals may be based on or derived from signals generated by each sensor, in particular by one yarn clearer, or by each sensor of several yarn clearers (e.g. different types of yarn clearers). The monitor signals may relate to a yarn supply bobbin identifier (see detailed description below) of the yarn supply bobbin received at the winding unit, yarn tension, number of clearing operations performed by the clearing system, energy consumption, number of yarn bobbins produced per unit time, etc. The monitor signals provided by or derived from the yarn clearer(s) may relate to yarn count, thick locations, thin locations, twist level, yarn strength, yarn elongation properties, tensile strength, twist and count, yarn hairiness, yarn imperfection index, yarn color, etc.

[0043] When the yarn supply bobbins 6 are produced by the spinning machine 5, the respective spinning parameters sp are applied. The yarn supply bobbins 6 are then transported to the winding machine 7 and then received at the winding machine 7. To determine the spinning parameters sp of the yarn supply bobbins 6 received at the winding machine 7, the yarn supply bobbins 6 may include an identification unit, such as an RFID tag (RFID: Radio Frequency Identifier), which stores a yarn supply bobbin identifier, for example in the form of a unique identification number. The spinning positions 51, 52, 53 of the spinning machine 5 and the winding positions 71, 72 of the winding machine 7 may be provided with reader units, such as RFID readers, so that the yarn supply bobbin identifiers of the yarn supply bobbins 6 located at the spinning positions 51, 52, 53, respectively, can be determined at the winding positions 71, 72 by reading the unique identification numbers from the identification units attached to each yarn supply bobbin 6. Thus, the electronic device 10 can receive and store the spinning parameters sp of the yarn supplying bobbin 6 produced by the spinning machine 5 and its yarn supplying bobbin identifier. Furthermore, the electronic device 10 can determine the spinning parameters of the yarn supplying bobbin 6 received at the winding machine 7 based on its yarn supplying bobbin identifier.

[0044] Alternatively or additionally, for example if a rail system for transporting the yarn supply bobbins 6 is arranged, a predefined transport plan can be applied for transporting the yarn supply bobbins 6 from the spinning machine 5 to the winding machine 7. The electronic device 10 can receive and store the spinning parameters sp of the produced yarn supply bobbins 6, which are assigned to this transport plan. The electronic device 10 can determine the spinning parameters sp of the yarn supply bobbins 6 received at the winding machine 7 based on the transport plan with the assigned spinning parameters sp.

[0045] 1, the spinning machine 5 produces yarn supply bobbins having reference numbers 61, 62, 63, and the winding machine 7 receives yarn supply bobbin yarns having different reference numbers 61, 65, 63, 68. The different reference numbers indicate that the yarn supply bobbins received at the winding machine may relate to yarn supply bobbins produced at various spinning positions on various upstream spinning machines.

[0046] As shown in Fig. 1, an electronic device 10 is arranged. The electronic device 10 includes a signal line interface (not shown) for connecting the electronic device 10 to respective signal line interfaces (not shown) of a spinning controller 50 of the spinning machine 5 and a winding controller 70 of the winding machine 7 via a signal line 1s. Typically, the electronic device is connected to several spinning machines and several winding machines. As shown in Fig. 1, the electronic device 10 may be connected to further upstream machines, such as a roving machine 3, via a signal line 1s.

[0047] The electronic device 10, the spinning controller 50, the winding controller 70, the signal line interface (not shown), the signal lines 1s, 5s, 7s, etc. may relate to a computerized device, a computerized network interface, and a computerized network. The computerized network may relate to a wired computer network, a wireless computer network, etc. The computerized network interface (not shown) may relate to a wired computer network interface, a wireless computer network interface, etc. The computerized network interface, the computerized network may enable protocols such as the Internet Protocol Suite, IEEE 802 standard, Ethernet technology, wireless LAN (commonly known as WLAN or WiFi), etc. The computerized network and the computerized network interface enable the transmission of control signals, monitor signals, etc. between each device, controller, unit, etc. The computerized device may relate to a microcontroller, a computer, etc. The computerized device may include one or more processors and program instructions stored in memory, which, when executed by the one or more processors, provide the functionality as described in this disclosure. The devices, controllers, units, etc. may include a user interface, such as a graphical user interface (GUI), to allow display of status information to an operator and / or to allow receipt of commands from an operator. For example, the electronic device 10 may be associated with a control and monitoring device for a spinning mill.

[0048] The roving yarn 4 or yarn supply bobbin 6 may be transported automatically, semi-automatically or manually from the roving frame 3 to the spinning frame 5 (or multiple such machines) or from the spinning frame 5 to the winding machine 7 (or multiple such machines). The yarn bobbin 8 may be transported automatically, semi-automatically or manually away from the winding machine 7.

[0049] The electronic device 10 is configured to receive from the spinning machine 5 spinning parameters sp related to the production of the yarn supplying bobbins 6. For this purpose, the spinning controller 50 transmits the spinning parameters sp to the electronic device 10 via the signal line 1s, for example by accessing the respective information of the control units 510, 520, 530 of the spinning units 511, 521, 531 upon request by the electronic device 10. For each produced yarn supplying bobbin 61, 62, 63, the respective spinning parameters sp (which may include the respective spinning positions 51, 52, 53) are received and can be assigned to the yarn supplying bobbin identifier of the yarn supplying bobbin 61, 62, 63 and stored.

[0050] The electronic device 10 is configured to receive from the winding machine 7 winding parameters wp related to the production of the yarn bobbins 8. For this purpose, the winding controller 70 transmits the winding parameters wp to the electronic device 10 via the signal line 1s, for example by accessing the respective information of the control units 710, 720 of the winding units 711, 721 upon request by the electronic device 10. For the produced yarn bobbins 81, 82 the respective winding parameters wp can be received and stored.

[0051] The electronic device 10 is configured to compare at least one winding parameter wp with a level defining a normal state of the at least one winding parameter wp in order to detect a winding anomaly. The comparison can be performed repeatedly, for example after a predefined time interval has elapsed. For example, the number of clearing operations per unit time, the number of winding errors per unit time, etc. can be compared with a level defining a normal number of clearing operations, winding errors, etc. per unit time. For example, if the deviation from the normal level exceeds a threshold value, a winding anomaly is detected.

[0052] For localization lc of a malfunction in the spinning and winding section 1, the electronic device 10 is configured to determine at least one spinning parameter sp of the yarn supply bobbin received at the winding machine 7 in case of a winding malfunction and to compare it with a level defining a normal state of this at least one spinning parameter. For example, a number of clearing operations at the winding machine 7 below a predefined limit may indicate a normal operation. For example, a number of clearing operations above a predefined limit may indicate a winding malfunction. In case of a winding malfunction, the electronic device 10 determines a spinning parameter sp of the yarn supply bobbin 61, 62, 63 received at the winding machine 7 and compares the spinning parameter with a level defining a normal state of this spinning parameter. For example, an imperfection index is compared with a level indicating a normal state. If the imperfection index does not have a normal state, a malfunction is determined in the spinning machine 5. If the imperfection index has a normal state, a malfunction is determined in the winding machine 7. For example, the winding parameters wp may include the identification of the winding position 71 with an abnormal number of clearings. For example, based on the yarn supplying bobbin identifier, the yarn supplying bobbin 6 received at the winding position 71 may be determined. For example, based on the yarn supplying bobbin identifier, an imperfection index of the yarn supplying bobbin 6 received at the winding position 71 may be determined. For example, if the imperfection index of the yarn supplying bobbin 6 received at the winding position 71 has a normal state, the electronic device 10 may be configured to locate this winding position 71 as a position of a malfunction in the spinning and winding section 1. If the imperfection index of the yarn supplying bobbin 6 received at the winding position 71 does not have a normal state, for example, if the imperfection index of the yarn supplying bobbin 6 received at the winding position 71 has an abnormal state, the electronic device 10 may be configured to determine from the spinning parameters sp the spinning position 52 which produced this yarn supplying bobbin 6 and locate this spinning position 52 as a position of a malfunction in the spinning and winding section 1.

[0053] FIG. 2 shows a schematic representation of an electronic device 10 for localizing malfunctions in an exemplary spinning and winding section 1 of a spinning mill with a number of spinning machines 5,5',5'',5'''',... and a number of winding machines 7,7',7'',.... Upstream of the spinning machines 5,5',5'',5'''',... a number of roving machines 3,3',... can be arranged for producing roving yarns 4. The roving yarns 4 are received at the spinning machines 5,5',5'',5'''',... for producing yarn supply bobbins 6 with wound yarn. The yarn supply bobbins 6 with wound yarn are received at the winding machines 7,7',7'',... for producing yarn bobbins 8.

[0054] As mentioned above, the electronic device 10 is configured to receive spinning parameters sp related to the production of the yarn supplying bobbins 6 from one or more spinning machines 5, 5', 5'', 5''', .... Furthermore, yarn supplying bobbin identifiers of the produced yarn supplying bobbins 6 can for example be received and stored together with the respective spinning parameters sp.

[0055] For this purpose, for example, as shown in FIG. 2, each yarn supplying bobbin 6 may include an identification unit id, such as an RFID tag (Radio Frequency Identifier) ​​or a barcode, and the spinning machines 5, 5', 5'', 5''', ... may be configured to determine the yarn supplying bobbin identifier by reading the unique identification number from the identification unit id, as described above.

[0056] The electronic device 10 controls the spinning controller 50, respectively, and can receive the yarn supplying bobbin identifier of the yarn supplying bobbin 6 by accessing the spinning controller 50. The electronic device 10 can access the further spinning parameters sp of the yarn supplying bobbin 6 and store the yarn supplying bobbin identifier of the yarn supplying bobbin 6, which is assigned to the further spinning parameters sp of the yarn supplying bobbin. During the production of the yarn supplying bobbin 6, the electronic device 10 can store the spinning parameters sp after a predefined time interval, after the production of a predefined amount of yarn, etc. This time interval, amount of yarn, etc. can be changed. For example, during a first stage of the production of the yarn supplying bobbin 6, a different time interval, amount of yarn, etc. can be selected than during a second stage. For example, during an initial stage of the production of the yarn supplying bobbin 6, a shorter time interval can be selected than during a final stage of the production of the yarn supplying bobbin 6. For example, according to the yarn wound on the yarn supplying bobbin 6, the electronic device 10 can store different imperfection indices, hairiness values, etc. for different sections of the yarn wound on the yarn supplying bobbin 6. Thus, the electronic device 10 may store for each produced yarn supplying bobbin 6 spinning parameters sp assigned to the yarn and / or yarn sections wound on the yarn supplying bobbin 6 together with a yarn supplying bobbin identifier of the yarn supplying bobbin 6. The spinning parameters sp may include the identification of the spinning machines 5, 5', 5'', 5''', ..., the identification of the spinning positions 51, 52, 51', 52', ... etc.

[0057] Thus, when a yarn supplying bobbin 6 is received at the winding machine 7, 7', 7'', ... for each winding position, the electronic device 10 can receive a yarn supplying bobbin identifier in order to determine spinning parameters sp of the yarn supplying bobbin 6. Furthermore, the electronic device can receive winding parameters wp related to the production of the yarn bobbin 8 from the winding machine 7, 7', 7'', .... The winding parameters wp can be related to the winding position of the winding machine 7, 7', 7'', ....

[0058] For this purpose, for example, the electronic device 10 can access the winding controllers 70 of the winders 7, 7', 7'', ... in order to receive respective information from the control units 710, 720 of the winding positions 711, 721 of the winders 7, 7', 7'', 7''', ....

[0059] To detect a winding anomaly, the electronic device 10 is configured to compare the at least one winding parameter wp with a level defining a normal state of said at least one winding parameter wp, as described above.

[0060] In case of a winding abnormality, the electronic device 10 is configured to determine spinning parameters of the yarn supplying bobbin 6 received at the winding machine 7, 7', 7'', ... and to compare them with levels defining the normal state of said spinning parameters, for localization lc of a malfunction in the spinning and winding section 1, as described above.

[0061] For example, for a particular winding position, a winding abnormality may result and the spinning parameters may have an abnormal state. The electronic device 10 can locate the malfunction at each spinning position based on the spinning parameters sp, which include the yarn supply bobbin identifier and the spinning position.

[0062] For example, for a particular winding position, a winding anomaly may result and the spinning parameters may have a normal state, and the electronic device 10 may be able to localize the malfunction at that winding position.

[0063] For example, if the electronic device 10 locates a malfunction at a particular spinning position, the electronic device 10 can determine further spinning positions that produce yarn supplying bobbins 6 having similar spinning parameters sp, such as imperfection index, hairiness, etc., and can locate these spinning positions as possible malfunctions even if the winding parameters wp do not yet indicate any abnormalities for the yarn supplying bobbins 6 produced at these spinning positions.

[0064] For example, the winding parameters wp may include parameters such as imperfection index, hairiness, etc. determined at the winding machines 7, 7', 7'', .... The localization of the malfunction can be based on the match of the respective spinning parameters sp and the winding parameters wp, e.g. imperfection index, hairiness, etc. Thus, if a yarn supplying bobbin 6 with a particular level of parameters such as a particular imperfection index, hairiness, etc. results in an abnormal condition, the spinning parameters sp can be used to identify all spinning positions which produce yarn supplying bobbins 6 with that particular level of parameters, thereby localizing the malfunction. For example, machine parameters may be incorrectly adjusted for a set of spinning positions.

[0065] For example, the winding parameter wp may include parameters such as imperfection index, hairiness, etc. determined in the winder 7, 7', 7'', .... Based on the yarn supplying bobbin identifier, the electronic device 10 can determine for each yarn supplying bobbin 6 the difference between each spinning parameter sp and the winding parameter wp. If this difference is greater than a predefined threshold, the transport of the yarn supplying bobbins 6 from the spinning machine 5, 5', 5'', 5''', ... to the winder 7, 7', 7'', ... can be localized as malfunctioning. For example, during transport the yarn supplying bobbins 6 may have been exposed to air with a high air humidity level.

[0066] The electronic device 10 may include neural network algorithms, fuzzy logic algorithms or the like to localize malfunctions in the spinning and winding section 1 based on the received spinning and winding parameters sp and wp.

[0067] Fig. 3 shows diagrammatically possible method steps of a method for localizing a malfunction in a spinning and winding section 1 of a spinning mill. The spinning and winding section 1 comprises one or more spinning machines 5,5',5'',5''',... and one or more winding machines 7,7',7'',.... The one or more spinning machines 5,5',5'',5''',... are configured to produce a plurality of yarn supply bobbins 6 with wound yarn. The one or more winding machines 7,7',7'',... are configured to receive the yarn supply bobbins 6 with wound yarn produced by the one or more spinning machines 5,5',5'',5''',... to produce yarn bobbins 8. The method comprises, in an electronic device 10 or a computer system, executing in step S1 a step of receiving spinning parameters sp of the produced yarn supply bobbins 6 from one or more spinning machines 5, 5', 5'', 5''', executing in step S2 a step of receiving winding parameters related to the production of yarn bobbins 8 from one or more winding machines 7, 7', 7'', ..., executing in step S3 a step of comparing at least one winding parameter wp with a level defining a normal state of the at least one winding parameter wp in order to detect a winding abnormality, executing in step S4 a step of determining the at least one spinning parameter sp and comparing it with a level defining a normal state of the at least one spinning parameter sp in case of a winding abnormality for localization lc of a malfunction in the spinning and winding section 1.

[0068] The yarn supply bobbins 6, 61, ... may in particular relate to a spun yarn wound on any type of carrier. The yarn bobbins 8, 81, ... may in particular relate to a rewound yarn, in particular to a spun yarn wound on any type of carrier. [Explanation of symbols]
