Description

Device and method for winding melt-spun threads

Technical Field

The invention relates to a device for winding a melt-spun thread consisting of a plurality of filaments. The invention also relates to a method for winding a melt-spun yarn.

Background

In the production of synthetic threads, molten polymer is fed to a spinning nozzle under high pressure by means of a spinning pump and extruded to form filaments. After extrusion and cooling, the filament strands are collected to form filaments. Many of the yarns thus produced are wound in parallel into bobbins in so-called winders.

Such winding machines have so-called winding spindles which have a chuck with clamping jaws with a clamp for receiving and fixing a winding tube, which are arranged on their circumferential surface. One winding tube per yarn to be wound can be placed on the winding spindle. The winding spindle can be mounted on one side and arranged to protrude on the spindle seat such that a bobbin wound on the circumference of the winding spindle can be removed from the free end of the winding spindle when completed. The removal of the bobbins is also referred to as doffing.

In winding bobbins, the respective thread is usually deposited by contact pressure rollers on the circumferential surface of the winding bobbin or the bobbin which has been partially wound, respectively. With a uniform distribution of the yarn mass in the bobbins, there is therefore also a uniform supporting effect of the contact pressure roller. However, due to the reversal of the thread at the end of the bobbin, thread aggregation may occur at the end of the bobbin. In addition, the slipping thread layer may cause an inconsistent mass distribution in the wound bobbin. Downstream processing of the respective wound bobbins can thus be compromised.

Disclosure of Invention

In view of the above background, the object of the present invention is to specify a device for winding a melt-spun thread, which ensures that the winding of the melt-spun thread forms a bobbin or winding bobbin, respectively, with improved quality. The object is likewise to specify a method for more reliably winding melt-spun threads in terms of quality.

This object has been achieved by the subject matter of the first aspect of the invention in terms of a device. In a twelfth aspect of the invention, the method according to the invention is specified explicitly. Advantageous embodiments are the subject matter of other aspects of the invention and will be explained below.

The device according to the invention for winding a melt-spun yarn consisting of a plurality of filaments has a winding spindle by means of which at least one spun yarn can be wound into a bobbin, at least one measuring device for measuring the peripheral temperature of the bobbin placed on the winding spindle, and an evaluation device for the temperature measurement result of the measuring device. The invention provides that the evaluation device is specifically designed to detect an uneven distribution of the mass of the wound thread portion on the bobbin on the basis of at least one evaluated temperature measurement.

The device according to the invention for winding a melt-spun yarn advantageously allows improved winding accuracy and thus overall higher winding bobbin quality. In the case of a uniform distribution of the thread mass in the respective bobbins, a uniform temperature distribution (profile) or nominal temperature is also established on the circumference of the bobbins. The reason for this is that a uniform support of the contact pressure roller used during winding is established, in particular also in the case of a uniform mass distribution.

The well-wound bobbin has temperature peaks and temperature valleys of approximately the same size along the outer circumference of the wound bobbin at winding reversal points, the temperature peaks and temperature valleys being symmetrical to one another as shown in the graph in which the temperature axis is shown over the bobbin width.

However, this may lead to a non-uniform temperature distribution or deviations from the nominal temperature of the circumference of the bobbin, as far as so-called yarn aggregation and thus a mass distribution inconsistency occurs when winding the yarn. In this way, the region of the bobbin with the yarn accumulation can be heated more strongly than the region in the vicinity due to the stronger contact pressure of the contact pressure roller. The yarn aggregation can thus be detected appropriately by measuring the temperature of the outer circumference of the bobbins placed on the winding spindles and by evaluating the respective measurement results. In the temperature distribution, this can be established by having temperature peaks and temperature valleys of different sizes in the graph.

Based on this detection, suitable measurements can be initiated, respectively, for example, classification of the respective bobbin in terms of quality change (variation), adjustment of the respective current winding process and also adjustment of the subsequent winding process.

According to an advantageous embodiment, the measuring device can be specifically designed to measure the temperature of the outer circumference of the rotating bobbin and/or of the bobbin during the positive winding of the spun yarn. The temperature measurement during winding ensures a higher accuracy in detecting yarn aggregation and thus non-uniformity of mass distribution. In particular, this prevents the uneven course of the wound bobbin from being obscured by the uniform course of the bobbin and prevents or completely prevents the detection of the uneven course of the bobbin.

It is also preferred that the at least one measuring device can be designed to measure the temperature in a contactless manner and/or be designed as an infrared camera and/or a pyrometer. As a result, the obstruction to the winding process can be completely avoided or limited to a minimum. The non-contact measurement of the temperature can take place in particular without the risk of the wire to be wound being caught in the measuring device.

According to one advantageous embodiment, the at least one measuring device can be arranged movably and/or displaceably, in particular in the longitudinal direction of the winding spindle and/or along a plurality of bobbin winding spindles arranged on the winding spindle and/or along the width of at least one bobbin arranged on the winding spindle. As a result of the arrangement of the measuring device in this way, temperature measurements can be carried out at a plurality of measuring points by means of the measuring device, so that a higher information density can be produced with respect to a bobbin or bobbins with respect to a potential inconsistency in the mass distribution. At the same time, the number of measuring devices can be kept low by the movable or movable measuring devices, as a result of which the production costs of the device for winding the spun thread can be reduced.

According to an even further advantageous embodiment, the at least one measuring device can be specifically designed to measure the peripheral temperature of the bobbin mounted on the winding spindle by means of a reflecting device, in particular a mirror. The reflection device can be arranged so as to be movable and/or movable, in particular in the longitudinal direction of the winding spindle and/or along a plurality of bobbin winding spindles arranged on the winding spindle and/or along the width of at least one bobbin arranged on the winding spindle. Because the measuring device is provided, there is a higher flexibility with respect to the setting of the measuring device. In particular, the latter do not necessarily point directly to the respective measuring point, but such an orientation can be achieved by a more compact and/or lighter reflecting device.

Furthermore, the movable arrangement of the reflection means also ensures that temperature measurements can be carried out at a plurality of measurement points with only one measuring means, so that a higher information density can be produced with respect to a bobbin or bobbins, which involves a potential inconsistency in the mass distribution. The mobility or mobility of the reflecting means, in particular of the mirror, can also be achieved with only a slight complexity in terms of construction and thus low production costs.

According to a further advantageous embodiment, a plurality of measuring devices can be provided, in particular a plurality of measuring devices arranged in the longitudinal direction of the winding spindle and/or along the plurality of bobbin winding spindles arranged on the winding spindle and/or along the width of at least one bobbin arranged on the winding spindle. The plurality of measuring devices allows simultaneous temperature measurements at a plurality of measuring points. In this way, a further improved information density can be produced which relates to a potential inconsistency of the mass distribution associated with the bobbin or bobbins.

According to a further advantageous embodiment, at least one measuring device for detecting the temperature of the outer circumferential end of the bobbin mounted on the winding spindle can be permanently and/or fixedly positioned. Due to the reversal of the threads, thread aggregation may occur to a particular extent at the respective ends of the bobbins. The permanent and/or fixed positioning of the at least one measuring device for measuring the temperature at the outer circumferential end of the bobbin and thus in the bobbin region can thus improve the detection accuracy or the detection reliability of the inconsistent mass distribution, respectively.

Even more preferably, the evaluation device can be specified as a non-uniform distribution of the detection mass on the basis of the evaluated temperature measurement results, because of the yarn aggregation of the wound yarn sections, in particular of the yarn aggregation at the end of the bobbin and/or of the yarn aggregation caused by the offset yarn layer. The detection accuracy and thus also the quality of the wound packages can thus be further improved.

Even more preferably, the at least one measuring device and/or the plurality of measuring devices can be specified to detect a temperature distribution along the bobbin width of the bobbins mounted on the winding spindles. The temperature change in the bobbin, in particular in the bobbin during the winding of the thread, can thus be detected very advantageously and evaluated by the evaluation unit. With only minimal evaluation complexity, significant temperature changes within the bobbins can allow conclusions to be drawn about yarn aggregation and inconsistent mass distribution. In particular, such an evaluation can be carried out without a nominal/actual comparison of the temperature data or without resorting to empirically determined temperature data, respectively.

It may also be advantageous if at least one measuring device is specifically designed to continuously detect the temperature and/or to detect the temperature of the outer circumference of the cartridge in a periodically reproduced manner, in particular at intervals of less than 20 seconds, preferably less than 10 seconds or less than 5 seconds. The temperature detection can likewise be carried out at intervals of less than 100 seconds, preferably less than 50 seconds or less than 30 seconds. Continuous temperature detection ensures high monitoring accuracy. In contrast, low complexity in terms of calculations for evaluating temperature measurements can be maintained because of the regularly reproduced temperature detection. In addition, the periodically reproduced temperature detection can be performed with fewer measuring devices performing temperature measurements at different measuring points at different times. The short intervals here ensure that the risk of not finding a wire aggregation is shortened.

Even more preferably, the at least one measuring device and/or the plurality of measuring devices can be specified to detect the temperature of the outer circumferential surface of a plurality or all of the bobbins arranged on the winding bobbin. It is also possible for at least one measuring device and/or a plurality of measuring devices to be specified in order to detect the temperature of the outer circumferential surface of certain bobbins arranged on the winding spindle. As a result, a comparison of temperatures between different bobbins can be made. In addition, the quality of a comparatively large number of bobbins wound simultaneously can be monitored in this way, and thus an overall improved result with respect to quality or an improved reliability with respect to quality can be obtained, respectively.

According to a further preferred embodiment, the evaluation device can be designed as part of the measuring device or can be separate from the measuring device, and/or the evaluation device and the measuring device can be designed as part of the detection system or together form the detection system. Such detection systems may be smart sensors and/or neural sensors. Such detection systems may be equipped with modules for artificial intelligence, in particular, to allow continuous improvements in terms of detection functionality.

According to a further preferred embodiment, the evaluation unit can be formed by a winding spindle control unit. As a result, complexity in terms of equipment can be reduced. The winding spindle control unit may be designed to control the operation of the winding spindle, for example to control the rotation and/or the acceleration and/or deceleration and/or braking of the winding spindle rotation.

The evaluation unit can preferably be designed as a module of the winding spindle control unit. In this way, an evaluation unit which is provided separately from the winding spindle control unit can be avoided. In this way, a very simple integration of the evaluation unit into the control unit of the entire device can be achieved.

According to one advantageous embodiment, the device for winding up the melt-spun thread can be configured with a traversing unit. Such a traversing unit can be specified explicitly as a thread to be wound on a bobbin by a defined winding stroke or as a respective thread section is dropped onto a defined position of the bobbin and guided appropriately for this purpose. Such a traversing unit can be designed, for example, as a double-rotor device.

According to an even more preferred embodiment, the evaluation unit can be formed by a traverse control unit. The traverse control unit may be a control unit for the traverse unit. The complexity in terms of equipment can also be reduced by designing the traverse control unit as an evaluation unit. The evaluation unit can be designed in particular as a module of a traverse control unit. As a result, an evaluation unit that is independently provided with respect to the traverse control unit can be avoided. Such a design also allows a simple integration of the evaluation unit into the control unit of the entire device.

The winding spindle control unit and the traverse control unit can also preferably be formed by an overall control unit, as a result of which the complexity in terms of equipment can also be reduced.

According to a further preferred embodiment, the evaluation unit can be specified explicitly to perform a nominal/actual comparison of the temperature data. The nominal temperature data can preferably be preset and/or can be preset and/or adjusted from the average value of the previous winding process. For example, the nominal temperature data may be an average of temperature data of a predetermined number of prior winding processes, such as an average of temperature data of at least 5, at least 10, at least 20, or at least 30 prior winding processes.

The nominal temperature data can likewise be an average value of temperature data of a predetermined number of other bobbins which are arranged on the winding spindle and which are subjected to the current winding process, for example an average value of temperature data of at least 3, at least 5, at least 10 or at least 15 other bobbins.

Such a nominal/actual comparison can be established only with little complexity and at the same time ensures a sufficiently reliable evaluation result. The presetting of the nominal temperature data can be carried out particularly simply. Any adjustment, in particular any continuous adjustment, of the nominal temperature data allows an improvement in the current evaluation accuracy or a continuous improvement in the quality assurance of the wound bobbins.

In a further preferred embodiment, the detected nominal/actual change of the evaluation unit based on the temperature values and/or the temperature distribution can be specified explicitly as an alarm signal for detecting the quality of the respective bobbin to be wound or of the respective wound bobbin. For example, a signal corresponding to a particular quality level may be emitted in relation to the detected nominal/actual change. The respective bobbins may then be marked and/or electronically identified and/or labeled based on the data in a manner corresponding to the respective quality class. The quality class can then be taken into account in the downstream processing of the bobbins.

In a further preferred embodiment, the evaluation unit, based on the detected nominal/actual change in the temperature value and/or the temperature profile, can be specified explicitly to emit control signals and/or information signals for adjusting at least one bobbin parameter and/or winding parameter. This can be a bobbin parameter and/or a winding parameter for the current and/or future winding process.

For example, the evaluation unit, based on the detected nominal/actual changes in the temperature values and/or the temperature distribution, can be specified explicitly to emit control signals and/or information signals for adjusting the mechanical and/or technical process setting conditions, respectively, for a future winding process or winding stroke by means of the winding spindle. Such control signals and/or information signals may be signals for automatic or self-adjusting of the setting conditions and/or signals for operator adjustment of the setting conditions for future winding processes or winding strokes of the winding spindle or automatically generated recommendations.

The evaluation unit, based on the detected nominal/actual changes in the temperature values and/or temperature profiles, can also be specified explicitly as a control and/or information signal for adjusting the mechanical and/or technical process setting conditions for the current winding process or current winding stroke during the operation of the winding spindle. Such control and/or information signals may be signals for automatic or self-adjusting of the setting conditions and/or signals for operator adjustment of the setting conditions for the current winding process or current winding stroke during the operation of the winding spindle or automatically generating recommendations.

The setting conditions for the current or future winding process or the current or future winding stroke, respectively, may be for example a dual rotor setting condition. This may be particularly advantageous when the attractive temperature profile is repeatedly or permanently measured.

Additionally or alternatively, the setting conditions for the current or future winding process or the current or future winding stroke, respectively, may be setting conditions for the drop angle of the wire to be dropped and wound on the respective wire. This may be particularly advantageous when the sliding thread layer is repeatedly or permanently detected or when temperature measurements and corresponding evaluations allow conclusions to be drawn on the sliding thread layer.

Another aspect of the invention relates to a method for winding a melt-spun yarn consisting of a plurality of filaments, in which method at least one spun yarn is wound into a bobbin on a winding spindle, in which method a measurement of the peripheral temperature of the bobbin arranged on the winding spindle is performed, in which method the measurement temperature of the measuring device is evaluated, and in which method an uneven distribution of the mass of the wound yarn portion is detected on the basis of at least one evaluated temperature measurement.

Such a method can be carried out particularly advantageously with the device for winding up melt-spun threads described above. The method according to the invention for winding a melt-spun yarn advantageously allows improved winding accuracy and thus overall higher quality of the wound bobbin.

In the case of a uniform distribution of the thread mass in the respective bobbins, a uniform or nominal temperature on the respective bobbin circumference is also established, since a uniform support of the contact pressure rollers for the winding is also established. If so-called yarn aggregation and hence a mass distribution inconsistency should occur in the yarn winding process, this may lead to a non-uniform temperature distribution or deviations from the nominal temperature of the bobbin circumference. The bearing pressure of the contact pressure roller causes that the region of the bobbin with the yarn accumulation can heat up more strongly than the adjacent region. Measuring the temperature of the outer circumference of the bobbins placed on the winding spindles and evaluating the respective measurement results advantageously allows detection of thread aggregation.

The preferred embodiments described above in relation to the device for winding up the melt-spun yarn also apply in a similar manner to the method for winding up the melt-spun yarn.

Detailed Description

Fig. 1 shows a schematic side view of an apparatus 10 for winding melt-spun yarn according to a first embodiment of the present invention. The device 10 is particularly designed for winding a melt-spun thread consisting of a plurality of filaments. Such melt spun filaments may be synthetic spun filaments.

The device 10 according to fig. 1 has a winding spindle 12, by means of which at least one spun thread, which is not shown in greater detail here, can be wound to form a bobbin 14. In fig. 1, a plurality of bobbins 14 are arranged on the winding spindle 12. The device 10 also has a measuring device 16 for measuring the temperature of the outer circumference of the bobbin 14 mounted on the winding spindle 12. The measuring device 16 may advantageously be a pyrometer and/or an infrared camera.

The device 10 finally has an evaluation device 20 for evaluating the temperature measurement obtained by means of the measurement device 16. The evaluation device 20 is in this case specified, based on the at least one evaluated temperature measurement, to detect a non-uniform distribution of the mass of the wound yarn portion on the bobbin 14.

In the embodiment according to fig. 1, the measuring device 16 is arranged movably or displaceably, in particular in the longitudinal direction 17 of the winding spindle 12, or in the plurality of bobbins 14 arranged on the winding spindle 12, and/or in the width of at least one bobbin 14 arranged on the winding spindle 12.

The mobility or mobility of the measuring device 16 is achieved, for example, by means of a support rail 22, on which the measuring device 16 can be moved. A linear drive may be provided for moving the measuring device 16 on the support rail 22. The support rail 22 can extend in particular in the longitudinal direction 17 of the winding spindle 12.

The detection of the temperature distribution along the bobbin width of the bobbins 14 mounted on the winding spindle 12 can take place in a simple manner due to the mobility or portability of the measuring device 16. Likewise, temperature measurements can be carried out on different or adjacent bobbins 14 mounted on the winding spindle 12, which are taken into account in the evaluation by means of the evaluation unit 20. For example, the temperature data of different bobbins 14 can be compared with one another.

Fig. 2 shows a side view of an apparatus 10 for winding melt-spun yarn according to a second embodiment of the present invention. The device 10 according to the embodiment of fig. 2 differs from the embodiment according to fig. 1 in the type of positioning or orientation of the measuring device 16. In the embodiment according to fig. 2, the measuring device 16 is then specifically designed to measure the temperature of the outer circumference 18 of the at least one bobbin 14 mounted on the winding spindle 12 by means of the reflecting device 24.

The measuring device 16 according to fig. 2 is thus directed to the reflecting device 24, and the reflection onto the outer circumferential surface 18 of the at least one bobbin 14 mounted on the winding spindle 12 takes place by means of the reflecting device 24. This allows for an overall compact construction mode. The reflecting means 24 may be in particular a mirror. The reflecting means 24 are preferably arranged movably and/or displaceably, in particular in the longitudinal direction 17 of the winding spindle 12 and/or in the width of a plurality of bobbins 14 arranged on the winding spindle 12 and/or in the width of at least one bobbin 14 arranged on the winding spindle 12.

The mobility or mobility of the reflection means 24 is achieved by the support rail 22, on which the reflection means 24 can be moved, for example. A linear drive may be provided for movement of the reflecting device 24 on the support rail 22. The support rail 22 may extend in particular in the longitudinal direction 17 of the winding spindle 12.

The detection of the temperature distribution along the bobbin width of the bobbins 14 mounted on the winding spindle 12 can take place in a simple manner due to the mobility or portability of the reflection device 24. Likewise, temperature measurements can be carried out on different or adjacent bobbins 14 mounted on the winding spindle 12, which can be taken into account in the evaluation by means of the evaluation unit 20. For example, the temperature data of different bobbins 14 can be compared with one another.

Fig. 3 shows a side view of an apparatus 10 for winding melt-spun yarn according to a third embodiment of the present invention. The device 10 according to the embodiment in fig. 3 differs from the embodiment according to fig. 1 or 2 with respect to the number of measuring devices 16 or their arrangement or orientation, respectively. A plurality of measuring devices 16 are then provided in the embodiment according to fig. 3. The measuring device 16 is in this case in particular along the longitudinal direction 17 of the winding spindle 12 and/or along a plurality of bobbins 14 arranged on the winding spindle 12 and/or along the width of at least one bobbin 14 arranged on the winding spindle 12.

According to fig. 3, the measuring device 16 is fixedly mounted or fixed relative to the winding spindle. The measuring device 16 can be arranged immovably at least in the longitudinal direction 17 of the winding spindle 12. At least one of the measuring devices 16 can be permanently and/or fixedly positioned to detect the temperature of the peripheral end 26 of the bobbin 14 mounted on the winding spindle 12. Preferably, a plurality of or all of the measuring devices 16 are permanently and/or fixedly positioned to detect the temperature of the peripheral end 26 of the bobbins 14 placed on the winding spindle 12. Temperature monitoring of the peripheral end 26 is advantageous for quality assurance, since wire accumulation is more likely to occur on the peripheral end 26 due to wire reversal during winding.

In the embodiment according to fig. 1 to 3, the evaluation device 20 is designed separately from the measuring device or devices 16. The evaluation device 20 can then form a separate component. However, it is also possible to design the evaluation device 20 as part of the respective measuring device 16 and/or to have a dedicated evaluation device 20 for each measuring device 16. In addition, the respective evaluation device 20 and the measurement device 16 can be designed as part of or form a detection system. Finally, the evaluation device 20 can also be formed by a bobbin control unit and/or a traverse control unit, which are not shown in more detail.

The device 10 according to the embodiment shown in fig. 1 to 3 is adapted to perform a method for winding a melt-spun yarn consisting of a plurality of filaments. In this method, at least one spun yarn is wound into a bobbin 14 at a winding spindle 12, a temperature measurement is performed on the outer periphery 18 of the bobbin 14 mounted on the winding spindle, and the measured temperature of the measuring device is evaluated. Finally, in this method, an uneven distribution of the mass of the wound wire portion may be detected based on the at least one evaluated temperature measurement.

Based on the detected nominal/actual change of the temperature value and/or the temperature profile, the respective evaluation unit 20 can emit an alarm signal for detecting the quality of the respective bobbin 14 to be wound or of the respective wound bobbin 14 and/or a control signal and/or an information signal for adjusting at least one bobbin parameter and/or winding parameter and/or traversing parameter of the current and/or future winding operation.

In this way, the quality of the respective bobbins 14 in the current winding operation can be influenced appropriately, or bobbins 14 having an inconsistent quality distribution can be identified with respect to a reduced quality class. Depending on the non-uniform distribution of the quality, the setting conditions and/or specification of the future winding operation may likewise be implemented to ensure quality or continuous improvement of quality assurance, respectively.
