- this information can thus be determined according to the invention directly on the single-spindle drive; This happens more precisely, more comprehensively and more promptly than in the exemplary embodiments mentioned in the prior art.
- the work of rewinding can thus be advantageously made more effective.
- the yarn length of the yarn wound on the cop can also be transmitted and the dishwasher can thus determine whether a cop has been completely unwound. All Not completely unwound cops can thus be fed back to the dishwasher.
- At least one section module can be present in the communication structure of the ring spinning machine, which is assigned to a multiplicity of decentralized control modules and which transmits the information about the shape or structure of the cops or about the created yarn from an assigned, decentralized control module from Section module queried and sent by this to the section module and evaluated there.

- Fig. 1 shows schematically a ring spinning machine with single spindle drive
- FIG. 3 schematically shows a ring spinning machine in conjunction with a winding machine
- Fig. 1 shows schematically a ring spinning machine 1 according to the invention, which has a plurality of juxtaposed spinning stations 2.
- the spinning stations 2 are arranged in a longitudinal direction x of the ring spinning machine 1 between a head 3i and a foot 3 2.
- Head 3i and foot 3 2 of the ring spinning machine 1 can contain bearings, drives, control, etc. which are suitable for the operation of the Machine are necessary.
- each spinning station 2 consists of a roving 4, which is arranged above a drafting 5, and on which a roving 6 is wound.
- the roving 6 runs from the roving bobbin 4 via the drafting device 5, where it is stretched to then be guided to a Garn Strukturelement.
- a circulating runner guides the finished yarn onto a cop 7 placed on a driven spindle 8.
- Fig. 2 shows schematically the communication system of the ring spinning machine 1.
- the ring spinning machine 1 has 8 single spindle drives 9 for driving the spindles, which drive the spindles 8.
- electrical drives are be, such as electric synchronous motors, asynchronous motors, brushless DC motors, etc. or equivalent motors used.
- Each individual spindle drive 9 is assigned a decentralized control module 10.
- the spindles 8, the individual spindle drives 9 and the control modules 10 are arranged on the spindle bank 22 of the ring spinning machine 1.
- the spindle rail 22 is shown only schematically and the components which are located on the spindle rail 22 are correspondingly in Fig. 2 within the element.
- the connections of the electrical drives 9 have connecting cables, which are combined on the spindle bank 22 and connected to a power supply at one end of the spindle bank.
- the connections to the electrical drives 9 are realized by plug connections.
- the control modules 10 have the task of monitoring the individual spindle drives 9 and implement commands from the higher-level control. Within the scope of the invention, it is conceivable that a plurality of decentralized control modules 10 of the individual spindle drives 9 are combined. A multiplicity of decentralized control modules 10, for example 64 control modules 10, communicate with a higher-level section control module 11, two of which are shown by way of example in FIG. However, the number of section control modules 1 1 will depend on the number of spindles 8, as indicated by the dashed control module 10. The section modules 1 1 process the information from the control modules 10 and forward the information. Several decentralized section control modules 1 1 communicate with a higher-level central control module 12 of the ring spinning machine 1.
- the central control module 12 is the central machine control, which has all machine data, these are processed and visualized statically.
- a display 20 is connected for this purpose.
- the machine data can be queried by the Be user via the display 20 at this point. It is also possible to forward this data to a mobile application.
- a machine data bus 13 is present between the central control module 12 and the section control modules 11, and a section data bus 14 is present between the section control modules 11 and the decentralized control modules 10.
- the section data bus 14 is responsible for the communication between control modules 10 and the section control modules 1 1; Over him are commands from the section module
- decentralized control modules 10 of the electric drives 9 can be addressed by the central control unit 12 via the communications network 15, for example a start / stop signal or a command for controlling the central control device 12 via the digital communications network 15 Acceleration or deceleration ramp to the decentralized control modules 10 are sent.
- FIG. 2 further shows command and signaling elements 17, with each individual spindle drive 9 being assigned exactly one command and signaling element 17.
- These command and message elements are arranged in the form of operating elements 17 on the ring rail 23 of the ring spinning machine 1.
- Several control modules 16 are connected via a section command bus 19 with the command and signaling elements 17 and superordinate them.
- a machine command bus 18 provides for the communication between the control modules 16 and the central module 12. If a control module 10 detects a deviation from the setpoint, this information is sent via the bus system 14, 13, 18, 19 to the associated signaling element 17 and there shown. The operator then has the option of executing a command (eg start or stop) on the ring rail 23 at the to input error element 17, which is then sent back to the control module 10 via the bus system 14, 13, 18, 19.
- a command eg start or stop
- the control module 10 itself performs an action, so for example, it can turn off the spindle in case of yarn breakage.
- a yarn breakage or a creep spindle can be determined on account of the power consumption. Due to the current shape, the speed, the rotor speed, the condition of the rotor, the operating state of the spindle, the bearing condition or bearing damage, the oil level, etc. can be determined for mechanical bearings. If the spindle 8 is equipped with a magnetic bearing, the weight of a cop 7 can additionally be determined via the current consumption of the active magnetic bearing. In the event of a yarn breakage and the associated change in power consumption, a particular decentralized control module 10 may report this to the section control module 11. However, the section module 1 1 can also query all associated decentralized control modules 10 in succession. The information thus obtained is then evaluated in succession and the operating states determined.
- the section module 11 has for determining the said operating states (computation) means for evaluating the information obtained.
- the computing means include means for forming a root mean square current consumption and transforming the current form.
- the Fourier transformation, the wavelet transformation and the Hilbert-Huang transformation with the Empirical Mode Decomposition are used in particular as the main constituent.
- the Fourier transformation in particular the short-time Fourier transformation, the Gabor transformation, the fast Fourier transformation or the discrete Fourier transformation in training can be used as a discrete cosine transformation or as a discrete sine transformation come.
- the wavelet transformation in particular the discrete wavelet transformation, the fast wavelet transformation, the wavelet packet transformation or the stationary one Wavelet transformation used.
- discrete, static characteristic quantities of the signals can be used and a transformation of the signals in the frequency range can be dispensed with.
- random variables such as the expected value, the absolute deviation, the variance, the skewness, the excess or the covariance are used as parameters.
- the signals can be correlated, in particular cross-correlated or autocorrelated.
- a combination of the transformed signals and the static characteristics can be displayed.
- the common intention is, in particular, to compare the actual measurement signal with the reference signal state in the context of the pattern recognition, wherein the reference signal can be generated from information of one or more neighboring spindles or read out from a memory. This is done in particular on the basis of specific features which are generated from the signal and combined in a feature tool on the basis of a statement about the similarity of the signals in question.
- control modules 10 have the above-mentioned (arithmetic) means in order to evaluate the operating states. These then send the result to the assigned section module 11 for further processing. Furthermore, the control modules 10 can use the information from the current signal of the electric drives 9 for speed control of the spindle 8, the rotor and the control of the thread tension.
- Fig. 3 shows schematically a ring spinning machine 1 and a dishwasher 24, which forms a machine combination by a connection in the form of a peg tray conveyor system 26 and a bidirectional interface 27 (shown schematically). It is also conceivable another suitable, automated or manual transport system within the scope of the invention. Thus, for example, the transport of the cops 7 could be transported manually with a carriage from the ring spinning machine 1 to the dishwasher 24. The dishwasher 24 rewinds the cops 7, which have been conveyed by means of the conveyor system 26 to a winding station, to cheeses 25. The dishwasher 24 is controlled by a controller 28 accordingly.
- the information obtained from the described single spindle drives 9 of the ring spinning machine 1 during the construction of the cop 7 and transmitted via the bidirectional interface 27 may include one or more of the following:
- This information is determined by the decentralized control modules 10 of the Einzelspindelan gear 9, for example via a speed measurement, the number of stops, etc. and is sent to the central control module 12.
- This information can be determined if, in addition to the above information about length meter, number and position of the thread breaks, etc., the position of the spinning ring and the height is processed relative to the cop 7.
- the patterns of power consumption and resulting torque absorption are taken into account to get this information from the single spindle drive 9.
- the cops are then either marked directly with an identification means such as RFID tag or an identification takes place via the peg tray conveyor system 26 so that the Spulmaschi- ne 24 can assign the information obtained to the respective cops 8.
- everyone Single spindle drive 9 detects the information for each created cop 7 by means of the control module 10.
- the evaluation and calculation of the information takes place - analogously to the information mentioned with reference to FIG. 2 - depending on the available computing capacity either directly in the decentralized control modules or in the section modules 1 1.
- the information is sent via the section modules 1 1 to the central control module 12.
- the central control module 12 forwards this information centrally via the bidirectional interface 27 to the dishwasher 24 for processing.
- the dishwasher 24 can be operated more specifically and efficiently when rewinding the cop 7 by the controller 28:
- the speed profile of the rewinding of the cops 7 can be adapted according to the information of the individual spindle drives 9:
- the individual shape of the cops 7 is conveyed and the rewinding speed may take into account the shape of the cops 7 (e.g., slowly for a small cop diameter and fast for a large cop diameter). This prevents thread breakage in the winding process and thus leads to higher efficiency in the winding process.
- the individual thread tension course of the cops 7 is transmitted and the rewinding speed can take into account the thread tension on the cop 7 (for example, low thread tensions occur when stopping). This prevents several layers from being pulled off the cop 7 at the same time and this leads to a sorting out of the cop 7.
- the thread can be pulled off tangentially from the cop. This allows a 'balloon-free' threadline during rewinding and thus prevents quality losses in the yarn (especially in hairiness).
