Description

Method for operating a textile machine and textile machine

Technical Field

The invention relates to a method for operating a textile machine, in particular a spinning machine, wherein product-related operating parameters of the textile machine are provided by a product management system. The invention also relates to a textile machine, in particular a spinning machine, comprising a control device and a product management system.

Background

It is known that yarns of different raw materials and/or different properties can be produced on textile machines, in particular spinning machines, which produce yarns. Here, the specific yarn is also called an article, and the production period of the specific yarn or the specific article is also called a lot. A particular product is associated with a particular set of operating parameters (also called process recipe) of the textile machine. The set of operating parameters refers to a set of setting variables for a selected working element of the textile machine. These setting variables may for example comprise the roller rotational speed or the nominal point of the working distance of the two opposing adjustable elements.

Nowadays, the operating parameters of textile machines can be changed in an automated manner or with software support. The set of operating parameters may be optimized, for example, in the test equipment and then stored in a database. It may therefore be desirable to apply the already created process recipe to a large number of textile machines, for example at different locations and/or used by different operators.

For this purpose, DE 102004014257 a1 describes a product or recipe management system for textile machine installations. These recipes can be centrally invoked and saved in the system. These recipes can also be edited in the control unit of the individual machines in the textile machine installation in order to adapt them to the specific individual machine. This takes into account the following issues: the set of operating parameters of the machine for different series of components and different working years cannot be easily summarised. Due to differences or signs of aging and manufacturing tolerances determined by the component series, the quality of the yarn produced may vary from machine to machine when the same recipe is used. Such differences can be partially compensated by increased material usage, but this is not economically desirable. In DE 102004014257 a1, the edited recipe is stored centrally in the textile machine installation, whereby a unique "machine recipe" is created for a specific machine. This may be a suitable solution for a closed system of a single facility, but in this form it is not possible or difficult to apply to recipes for machines in different locations and/or with different operators.

Disclosure of Invention

In view of the above, it is an object of the present invention to improve the prior art with respect to the above-mentioned drawbacks.

The solution of the invention to achieve the above object consists in a method and a textile machine having the features described in the independent claims.

In the method according to the invention for operating a textile machine, in particular a spinning machine, product-related operating parameters are provided to the textile machine by a product management system. According to the invention, it is proposed that the product-related operating parameter is provided as a constant value; continuing to provide machine dependent correction factors; and calculating operating parameters adapted to the individual conditions of the textile machine on the basis of the product-related operating parameters and the correction factors.

The product management system is particularly a database and a user interface for controlling the connection mechanism of the textile machine and providing the textile machine with product-related operating parameters. As mentioned above, the product-related operating parameter is a set of settings for different components of the textile machine, which enables the textile machine to produce a certain product from a certain raw material having a certain characteristic. A typical raw material is cotton, for example, and the most important characteristics of the yarn include its thickness, hairiness and twist. Typical setting values may be, for example, certain rotational speeds or rotational speed ratios of certain components that are particularly suitable for producing the article.

With the method according to the invention, the operating parameters or recipes associated with the article are strictly separated from the operating parameters individually adapted to the respective machine. The provision of formulations which can yield products of the same quality when applied to machines of different component families and different operating years is achieved by machine dependent correction factors. Manufacturing tolerances of different software versions and/or components of a single machine can also be compensated in this way. The machine-dependent correction factors can be determined by the manufacturer during the assembly of the machine, can be provided together with the machine, and can also be integrated into the product management system if necessary. Also, as described below, the machine-related correction factors can be determined by the operator at machine start-up or after a batch change.

As mentioned above, the product-related operating parameters can be generated in the testing device, for example by the textile machine manufacturer. They can be provided to the respective operators in the form of a database. The database may be stored locally at the operator's location or on a networked manufacturer server. In addition to the operating parameters, such a database preferably also contains information about the products it is to produce and the time at which the operating parameters were generated.

It is also conceivable that the respective operator of the textile machine generates and stores the product-related operating parameters in person. This can of course also be combined with the possibilities described above, so that the set of product-related operating parameters provided by the manufacturer can be supplemented by the respective operator. But preferably, once the article-related operating parameters are determined for a certain product, these parameters are not altered anymore.

In the particular case of spinning machines, in particular rotor spinning machines, the product-related operating parameters may include, for example, the tension delay and in particular the rotational speed of the rotor and the opening rollers. These parameters are in turn determined, for example, by the control values of the electric motors controlling the respective components. On the one hand, it is conceivable to store higher-level parameters (for example, the rotational speed) in the product management system, which parameters are converted into corresponding control values by the control device of the textile machine when applied. On the other hand, it is also contemplated that basic parameters such as motor control values may be stored in the work-in-process management system and made available for direct application. The same applies to the correction coefficients and the adapted operating parameters.

The correction factors are values which allow the product-related operating parameters to be adapted to the conditions which individually exist for a particular textile machine. The correction coefficients are typically valid only for a particular machine, as compared to the data provided by the artifact management system. Accordingly, a correction factor must also be created for that particular machine and preferably stored on that machine.

The correction factor can be determined by the operator of the textile machine, for example by directly fine-tuning the correction factor, until the desired quality or the desired properties of the manufactured product are set. For this purpose, the textile machine or the control device of the textile machine preferably has a corresponding user interface. In particular, it is conceivable that the manufacturer already determines the first set of correction factors when manufacturing the textile machine or when starting up the textile machine for the first time.

For example, it is contemplated that an operator manually adjusts the settings of a particular component based on product-related operating parameters provided by a product management system until a desired quality or desired characteristics of the manufactured product are set. The textile machine or the control device of the textile machine can then calculate the correction factor independently, for example from the difference between the data of the product management system and the manually adjusted setting values of the textile machine components, and then preferably store this at the textile machine.

In addition or exclusively to the above, it is also conceivable to use sensors of the textile machine, in particular sensors for yarn monitoring, to adapt certain component settings or to adapt correction factors directly until the desired quality and/or the desired properties of the produced product are adjusted. In this way, for example, the textile machine or a control device of the textile machine can determine the correction factor independently.

As already mentioned, the correction factors are preferably stored locally at the textile machine, for example in a memory connected to the control device. However, it is of course also conceivable to store correction factors for different textile machines centrally in the installation. In addition to the correction factors, information is kept concerning, among other things, the correlation of the correction factors with the operating parameters associated with the respective product. Furthermore, information about the textile machine, such as the type and/or the service life of the installed components and the possible working life of the entire textile machine, for example, can also be saved. The correction factors can be modified preferably via a corresponding user interface.

In the control device of the textile machine, the product-related operating parameters and the correction factors are preferably converted into adapted operating parameters. It is also contemplated that the computing operations may be performed, for example, by an external computer system. Once the operator has set up the machine for a new batch in the conventional manner, the calculation can be carried out automatically by the control device. In principle, however, it is also conceivable to adapt the operating parameters only at the request of the operator. Although referred to as correction coefficients, other mathematical operations besides multiplication are also contemplated. These operations include, for example, addition, subtraction, and/or exponentiation.

The result of this calculation is adapted operating parameters which are preferably transmitted from the control device of the textile machine to the individual components to be set and applied to those components. The adapted operating parameters are preferably not permanently saved but recalculated for each batch. This may facilitate separation between article-related operating parameters of the article management system and adapted operating parameters that are valid only for the particular machine.

It is advantageous for the method to optionally, i.e. if necessary, readjust the correction factor. This indicates that if the product does not achieve the desired result despite the correct selection of operating parameters and correction coefficients, the correction coefficients will be re-determined. The individual conditions of the textile machine may change over time. These changes include mainly the signs of ageing of the components. It is therefore advantageous to adapt the correction coefficients to ensure that the product quality is always stable. For example, the adaptation may be performed manually by an operator entering new correction coefficients. However, it is also conceivable for the operator to readjust individual settings of the textile machine and to derive new correction factors from the differences between the settings and the operating parameters associated with the product provided by the product management system, which are then stored.

It is also advantageous that the realignment of the correction factors is performed automatically. This may depend, for example, on the particular component or the working age of the entire textile machine. Some sensor data may also be used to adapt the correction coefficients.

It is particularly advantageous to readjust the correction factor on the basis of the power consumption, the rate of filament breakage and/or the yarn hairiness of the individual components. The power consumption may for example indicate some signs of wear, which must be compensated for to ensure that the product quality is always stable. From an economic point of view, it is necessary to avoid excessively high yarn breakage rates, since the textile machines for yarn production or yarn processing are shut down at least for a short time each time a yarn breakage occurs. The rate of filament breakage can be reduced by adapting certain operating parameters. In this connection, an improvement can be achieved in particular by reducing the production speed by means of a correction factor. Hairiness is a typical quality characteristic of a spun yarn and has to react correspondingly to changes by adapting the operating parameters. In this connection, corrective measures can also be taken by modifying the production speed by means of the correction factor.

It is also advantageous to store the correction factors at the textile machine and to reapply them to the operating parameters provided when changing batches. In this way, the product-related operating parameters of the product management system can be kept separate from the operating parameters adapted to the respective textile machine. When the batch is replaced, the quality of the prepared product can be ensured to be stable all the time by reapplication. As described above, when a lot is changed, it is switched from manufacturing one product to manufacturing another product or lot. With the existing correction factors, batch changes can be done without time consuming manual adjustment of the textile machine.

Each textile machine preferably has a memory for storing the correction factor, which memory is connected in particular to a control device of the textile machine. Alternatively, it is also conceivable to store the correction factors at least for a specific operator of the textile machine and/or to store the correction factors centrally in the installation. For this purpose, existing textile machine networks and central data processing systems can be used. It is also conceivable to store the correction factors in a memory associated with the textile machine, such as a mobile data carrier.

In an advantageous development of the method, the permissible value range of the one or more correction factors is stored in the product management system. Whereby the correction factor is applied only if the calculated or otherwise determined correction factor is within the allowed value range. By limiting the correction factor in this way, it is ensured that all setting values remain within the predetermined safety parameters despite the adaptation by the correction factor. This improves the safety of the textile machine and the service life of the components. It is also conceivable to store the limit values of the adapted operating parameters in the work product management system, which in turn limits the possible value ranges of the correction factors. The value ranges of the correction factors can be displayed in a corresponding user interface on a display element of the textile machine.

It is particularly advantageous if the individual condition of the textile machine which can be compensated by the correction factor is an individual condition which is determined by aging signs and/or manufacturing tolerances and/or design. These conditions have a particularly strong influence on the quality of the products produced. Therefore, care should be taken to compensate for this. By compensating the aging signs, in particular the wear, by means of the correction factor, the worn parts can be replaced later and operating costs can be saved. In spinning machines, in particular rotor spinning machines, the signs of ageing may include, for example, wear of the opening rollers or opening roller sets, the drawing nozzle and the spinning rotor, and age-dependent belt expansion. Wear of the take-up and take-off roller linings may also be involved. The influence of manufacturing tolerances and/or assembly tolerances may, for example, be manifested as slightly different gap sizes, component sizes, moments of inertia of the rotating components and/or different degrees of efficiency of the electrical components. The conditions for the determination of the structural type include, for example, different characteristic factors of different components, different software versions and/or different performances of the electronic device.

More advantageously, the operating parameters comprise the rotational speed and/or the rotational speed ratio and/or the switch-on time and/or the number of movements, in particular the number of revolutions, of one or more components.

In particular, by modifying the rotation speed of the rotating member, it is possible to compensate for many conditions prevalent in textile machines, which have a negative effect on the quality of the products produced. The rotational speed is in turn dependent here primarily on the operating parameters of the drive motor. In particular, it can be adapted by means of correction coefficients. Both an increase and a decrease in the rotational speed may be advantageous. In the case of rotor spinning machines, for example, when the opening roller set is worn out due to aging, the rotational speed of the opening rollers can be adapted by a correction factor to ensure uniform opening of the fiber band. Other rotating members include spinning rotors, take-up rollers and coning drive rollers, among others.

The rotational speed is proportional to the tension delay of the spinning machine, for example, which can change as a result of wear of the linings of the take-up and take-off rollers.

For example, when cleaning the rotor, the switch-on time of the pneumatic or mechanical cleaning element can be specified for a specific product and adapted to the current machine conditions by means of a correction factor. In this case, the wear of the cleaning elements can also be compensated by a correction factor. The filaments are looked up pneumatically and also a specific on-time of the mouthpiece can be specified as an operating parameter. The operating parameters may also include the on-time of the pneumatic or mechanical yarn end preparation.

On the other hand, the rotational speed or the switch-on time is less important than the number of revolutions or movements, for example to provide a certain length of yarn or fiber material or to obtain a certain position of the component, in the case of other components. Here, for example, the filaments are fed back from the bobbin by a bobbin drive.

It is further advantageous to provide correction factors for individual stations of the textile machine and/or for a group of stations and/or for the entire textile machine. Modern textile machines sometimes contain a large number of independent work units. The smallest production unit is generally referred to as a workstation. An autonomous workstation of the textile machine receives power and control commands from the textile machine, but is otherwise independent of other workstations. Accordingly, they are each provided with a complete set of components, and different individual conditions may occur at different stations. Different stations of the same textile machine can also produce different products. Thus, it may be desirable to determine different correction factors for different workstations.

It is also advantageous if the operating parameters provided and/or the correction factors and/or the adapted operating parameters are displayed on a display element of the textile machine. It is particularly advantageous to display the provided operating parameters together with the correction factors and/or the adapted operating parameters on a display element of the textile machine. This is particularly advantageous for manual re-alignment of the correction factors and/or the adapted operating parameters. In particular, if the product management system predetermines a value range of the correction factor and/or the adapted operating parameter, this value range can likewise be displayed. Depending on the magnitude of the correction factor, the operator can also assess whether maintenance or replacement of components of the textile machine is imminent. However, it is also conceivable that, although the provided operating parameters have been corrected by means of the correction factor, the adapted operating parameters are not displayed, but only the provided operating parameters.

According to a development of the method, it is advantageous to generate new product-related operating parameters by means of correction factors calculated on the basis of current settings and/or adapted operating parameters of the textile machine.

For example, on a textile machine, the production of a new product lacking product-related operating parameters can be started, using product-related operating parameters of similar products. The correction coefficients, preferably stored at the machine as described above, are then applied to the article-related operating parameters of these similar articles to provide adapted operating parameters that match the similar articles. The operator then optionally continues to perform a number of tests to re-tune these parameters until the desired yarn quality for the new product can also be achieved using the current settings. The correction factor is then "subtracted" from the current setting value, thereby obtaining new product-related operating parameters for the new product. These parameters can also be stored in the work in process management system.

Of course, the article-related operating parameters of a particular article can also be altered in a similar manner. For example, if proper selection of the article-related operating parameters and correction factors does not achieve the desired result, while it may be excluded that this is due to current machine conditions, this may indicate that the article-related parameters must be changed. In this case, the correction coefficients are not re-aligned, but the adapted operating parameters are re-aligned until the desired result is obtained. Then, as described above, the correction factor is subtracted from these adapted and re-aligned operating parameters, and new article-related operating parameters for that particular article are calculated and fed back to the article management system.

In a further advantageous embodiment of the method, the correction factor is stored together with information about the textile machine in a database which is independent of the textile machine. This database can be used in particular for further development of the textile machine or for future provision of product-related operating parameters by the manufacturer. The relationship between the operating age of the component and the correction factor necessary to compensate for the signs of aging can also be derived.

It is particularly advantageous in this connection if the database is part of an expert system. The expert system is a computer program that can derive and extrapolate general relationships from the database from parameters for which causal relationships exist. Such a system is able to derive from general information about the textile machine, correction factors independently, such as the working age of the textile machine and its various working elements, and corresponding correction factors set manually in the past. Sensor data and/or data relating to the power consumption of the components of the textile machine can also be used to train an expert system and automatically determine the correction factors accordingly. It is also conceivable for the support operator to realign the correction factors by means of an expert system.

For a textile machine comprising a control device and a product management system according to the invention, the control device is configured to receive a product-related operating parameter provided by the product management system as a constant value and to calculate an operating parameter adapted to an individual condition of the textile machine on the basis of the product-related operating parameter and a machine-related correction factor.

The textile machine is in particular configured to carry out the above-described method. The advantages already described with respect to the method therefore also apply to the textile machine according to the invention.

The textile machine can be, for example, a spinning machine, in particular a rotor spinning machine. It may have several stations that are substantially independent of each other, preferably divided into a plurality of functional groups. For the exchange of data, the textile machine preferably has a corresponding interface, for example a network interface. Typical relevant operating parameters of the textile machine are in particular the current and the voltage of the installed motor. Furthermore, the textile machine preferably has a data memory which is suitable for storing the correction factor. Which is connected, for example, to a control device of the textile machine. The textile machine preferably has a display for displaying the product-related operating parameter and/or the correction factor and/or a possible correction factor or a predetermined value range of the adapted operating parameter. This can also be used in the user interface to manually re-align the correction factors.

Further advantages of the invention are described below in connection with the examples. In the figure:

figure 1 shows a schematic view of the execution of the method according to the invention on a textile machine;

figure 2 shows a schematic view of the execution of the method according to the invention on two textile machines; and

fig. 3 shows a schematic view of the execution of the method according to the invention on a textile machine with an expert system.

Detailed Description

In the following detailed description, the same reference numerals are used in the different figures for identical and/or at least equivalent features. Individual features, their design and/or mode of operation are usually described in detail only when first mentioned. If individual features are not specified again, their design and/or mode of action correspond to the design and mode of action of the equivalent or comparable features already described.

Fig. 1 shows a schematic view of a textile machine 1, intended to illustrate the process of the method according to the invention. The textile machine 1 is designed, for example, as a rotor spinning machine. It has several stations 2 which are substantially independent of each other. The textile machine 1 also has a product management system 3 which provides product-related operating parameters 5 to a control device 4 of the textile machine 1. In the control device 4 of the textile machine 1, the product-related operating parameters 5 are converted, for example using a correction factor 6 stored at the textile machine 1, for example, in order to generate operating parameters 7 which are adapted to the individual conditions of the textile machine 1.

The product-related operating parameters 5 of the product management system 3 can be generated, for example, by the manufacturer of the textile machine 1 and made available to an operator. It is also conceivable that the product-related operating parameters 5 are generated by the operator himself and/or are provided, for example, only to the textile machine 1 of a specific installation.

Typical operating parameters that can be assigned to spinning a specific yarn in a rotor spinning machine include, in particular, the current and voltage of the electric motor or the control signals in general, which influence, in particular, the rotational speed of certain rotating members. For example, the rotational speeds of the opening roller, the spinning rotor and the take-off roller must be set in this way.

Individual conditions of the textile machine 1, including, for example, signs of ageing or wear, manufacturing tolerances of components of the textile machine 1 and the proprietary properties of certain component series, can be compensated by the correction factor 6. For example, in the opening roller or opening roller group, the wear can have a negative effect on the quality of the end product. Similar effects can occur as a result of wear of the bearings, belts and/or friction linings of the motors and rollers. Also, the wear of the rotor belt under the central rotor drive of the spinning machine may have a negative effect on the spinning. These effects can be at least partially compensated by a corresponding correction factor 6. Manufacturing tolerances include, for example, slight differences in the moment of inertia or power curve of the motor. The specific properties of the component series include, inter alia, the characteristic parameters of the installed components and the software of the control device 4 of the textile machine 1.

The correction factor 6 is stored, for example, in the form of a decimal value which is multiplied by the product-related operating parameter 5. The result of this mathematical operation is an operating parameter 7 adapted to the individual conditions of the textile machine 1.

The correction factor 6 is determined for the first time by an operator of the textile machine 1 and the correction factor 6 is preferably stored in a memory of the textile machine 1. On the one hand, the correction factor 6 can be set directly by the operator. However, it is also conceivable that the operator can adjust the operating parameters 7 to improve the quality of the product manufactured by the textile machine 1. The textile machine 1 can derive a correction factor 6 in particular independently of the deviation between the product-related operating parameter 5 and the adapted operating parameter 7 and store it in a memory of the textile machine 1 as appropriate. In order to react to future changes in the individual conditions of the textile machine 1, the correction factor 6 can also be readjusted by the operator, for example. For example, with such a correction factor 6, the rotational speed of the rotor drive can be automatically tracked as a function of wear, wherein a previously determined correction factor 6 can also be used.

The textile machine 1 shown schematically also has a display 8, which display 8 is intended above all for displaying the product-related operating parameters 5 and the correction factors 6 and/or the adapted operating parameters 7. The display 8 makes it easier for the operator to realign the correction factor 6 or the adapted operating parameter 7.

Fig. 2 shows the textile machine 1 of fig. 1, with the difference that the control device 4 of the textile machine 1 is connected to an expert system 9. The expert system 9 comprises a database of correction factors 6, which correction factors 6 are associated with information about the individual condition of the textile machine 1. The expert system 9 can generate the correction factor 6 for the textile machine 1 independently from this data and/or assist the operator in realigning the correction factor 6.

The database of the expert system 9 can consist of the correction factors 6 already set at the textile machine 1 shown and/or the correction factors 6 of the other textile machines 1. It is conceivable to integrate the expert system 9 into the product management system 3.

Fig. 3 is intended to illustrate the most widespread use of the article-related operating parameters 5 of the article management system 3. The figure shows two textile machines 1 which receive the same product-related operating parameters 5 from the product management system 3. Although the individual conditions of the two textile machines 1 may vary greatly, the same product-related operating parameters 5 result in substantially the same end product. This is achieved by applying different correction factors 6 to the two textile machines 1. The adapted operating parameters 7 calculated on the basis of the product-related operating parameters 5 and the correction factors 6 differ accordingly between the two textile machines 1 and compensate for individual conditions which may have an adverse effect on the product quality.

The invention is not limited to the embodiments shown in the drawings and described herein. Combinations of features shown and described in different embodiments are equally possible within the scope of the claims.
