Description

[0001] The present invention relates to a method for operating a cross-wound spinning textile machine, in particular an open-end rotor spinning machine, with a plurality of identical workstations arranged side by side. Each workstation has a feed device for supplying a yarn, in particular a spinning device, and a winding device for winding the yarn onto a cross-wound bobbin. Each workstation is assigned a graphic display for showing information about the respective workstation in text or symbol form. The textile machine has at least one control device for controlling the current display output. The invention further relates to a corresponding cross-wound spinning textile machine.

[0002] Cross-coil-producing textile machines are known in the prior art, for example, in the form of rotor spinning machines, air-jet spinning machines, or winding machines. In modern textile machines, it has become increasingly common to operate the individual workstations independently of one another. For this purpose, the workstations have at least some individually driveable working elements and a workstation-specific control device. To provide the operating personnel with information about each workstation, it is already known to assign workstation-specific display devices to the workstations.

[0003] For example, German patent DE 199 30 714 B4 discloses the use of an individual display device at each workstation. The individual control devices at each workstation are connected to a higher-level control device of the textile machine. The individual display device can also be combined with the individual control device at each workstation. The display can be changed by pressing a button, depending on the number and / or type of press, to display different information sequentially.

[0004] German patent application DE 10 2019 116 646 A1 also discloses a textile machine in which each workstation is assigned a display. It is also conceivable that two or more workstations share a single display. As soon as a workstation reaches the end of its batch, the workstation is shut down and a requirement for manual maintenance is displayed on its screen. The operator thus does not need to press a button to be notified that work needs to be performed at a workstation during a batch change.

[0005] Nevertheless, the problem with the aforementioned textile machines is that the operating personnel can only recognize with difficulty at which work points operator intervention is required.

[0006] The object of the present invention is to eliminate the disadvantages known from the prior art, in particular to propose a method for operating a cross-coil-producing textile machine and a cross-coil-producing textile machine which enable improved operator guidance.

[0007] The problem is solved by a method for operating a cross-coil-producing machine and a cross-coil-producing textile machine with the features of the independent patent claims.

[0008] In a method for operating a cross-wound spool-producing textile machine with a plurality of identical, adjacent workstations, each workstation has a delivery device for supplying a thread and a winding device for winding the thread onto a cross-wound spool. Each workstation is assigned a graphic display for showing information about the respective workstation in text and / or symbol form. The textile machine has at least one control device for controlling the current display output.

[0009] It is proposed that the control device or another control device be used to adjust the brightness and / or light signal of the display depending on the operating state of the workstation, whereby an increased brightness and / or a modulating display of the associated display is set for a workstation requiring operation, and a reduced brightness and / or a continuous display of the associated display is set for a workstation not requiring operation.

[0010] A modulating display is understood to be a time-changing display, which may include, for example, blinking, a fade-in or fade-out, a pulsing of brightness, or any other time-changing display.

[0011] This design offers the advantage that operators can easily identify, from a distance, which workstations require attention and which do not, thanks to the brightly illuminated or modulating display indicators. This allows operators to directly access the workstations requiring attention without having to go to each individual workstation to check the display. As a result, operators can resolve malfunctions more quickly, thereby increasing machine efficiency. Furthermore, this significantly extends the lifespan of the displays and prevents premature failure.

[0012] Advantageously, the brightness of the workstations requiring operation is adjusted to a level, or a modulating display is set, at which the operator can easily read the information displayed while standing in front of the workstation. The displays of the workstations not requiring operation, on the other hand, can be dimmed, if the brightness is adjusted and, if applicable, if the display is set to continuous operation, to the point where the information is just barely visible. This allows the operator to read information about the operating status of the workstations even at the workstations not requiring operation. Alternatively, the displays of the workstations not requiring operation can be completely dimmed and only activated, for example, when requested by the operator.

[0013] The operational requirements of workstations can include, for example, a request for an operator to perform specific maintenance tasks, clean or replace certain components, or provide materials at the workstation, such as during a batch change. Similarly, operational requirements can include a technical alarm, a yarn alarm, or a quality alarm. A workstation that does not require operation, on the other hand, is either in regular operation, in standby mode, switched off, or defective.

[0014] The same advantages can also be achieved with a corresponding textile machine, for which protection is also claimed. In the textile machine, the brightness and / or light signal of the display can be adjusted by means of the control device or another control device, depending on the operating status of the workstation. The control device is designed to set increased brightness and / or a modulating display for an operator-occupied workstation, and reduced brightness and / or a continuous display for an operator-unoccupied workstation.

[0015] The textile machine is advantageously designed as a spinning machine, in particular as an open-end rotor spinning machine. The delivery device is in this case designed as a spinning device, in particular as an open-end spinning device.

[0016] In cross-coil-producing textile machines, it is advantageous for the control device for managing the current display output to be a workstation-specific control device. This control device can advantageously be combined with the workstation-specific display. Particularly in textile machines with many workstations, this allows each individual workstation to quickly adjust its display output. Alternatively, however, it would also be conceivable for the control device for managing the current display output of the workstations to be a central control device that manages multiple displays across multiple workstations.

[0017] In this process, it is further advantageous if, at the start of an operator intervention at a workstation, the brightness of the corresponding display is increased and / or the modulating display is activated. For example, if the display of a workstation that initially does not require operation is set to reduced brightness, continuous display, or is deactivated, and the operator nevertheless initiates an operation, the display can be automatically set to increased brightness and / or modulating display, for example, by touching the display. It is also conceivable that the level of increased brightness set at the start of an operator intervention at a workstation is brighter than that of the workstations requiring operation.Similarly, at a workstation requiring operation, which is already illuminated at a higher brightness, the operator can further increase the brightness once they begin working. In other words, a medium brightness level could be set at workstations requiring operation, which still allows for good visibility. Then, as soon as the operator begins work there, the brightness could be increased further to improve the readability of the display. However, it is also possible for the brightness level of workstations requiring operation to be the same as that of workstations where an operation has just begun.

[0018] It is also advantageous if, after an operator intervention is completed, the reduced brightness and / or the continuous display of the corresponding indicator is restored. This can be done automatically, for example, as soon as the workstation registers the completion of the operator intervention. However, it would also be conceivable to reduce the brightness at a workstation requiring or currently being operated only after confirmation by the operator, or to restore the dimmed continuous display.

[0019] In this method, it is further advantageous if the increased brightness and / or the modulating display is set for a predetermined period, and after this period has elapsed, the reduced brightness and / or continuous display is activated. The time period is preferably chosen so that the usual operator tasks can be completed within this time. This eliminates the need for the operator to also adjust the brightness level. Setting the increased brightness and / or the modulating display for a predetermined period can also be used if the operator activates the display themselves at the start of an operation.

[0020] It is also advantageous to set a time delay for the reduced brightness and / or continuous display of the corresponding screen. This allows operating personnel to see, even some time after the fact, at which workstations an operator intervention has just taken place.

[0021] Furthermore, it is advantageous if the increased brightness is set in the form of a light signal, preferably being set gradually, continuously, or in steps, or being set as a pulsating display. This allows not only the information that an operation is required at the workstation, but also other information to be conveyed to the operating personnel via various light signals.

[0022] It is also advantageous if the modulating display is set depending on the operating status of the workstation, the type of required operator intervention, and / or the operator's required qualifications. This allows, for example, communication of whether the operational requirement at the workstation is a simple operating request, a technical alarm, or a yarn alarm. Similarly, different modulating displays, such as pulsing, fade-in, or fade-out, can be used to address different user groups. For instance, a specific light signal can be used to indicate the presence of an operator with special qualifications. This can also be combined with increased brightness.

[0023] According to an advantageous embodiment of the invention, a level of reduced brightness and / or a level of increased brightness(s) and / or the type of modulating display of the indicators are set centrally, in particular centrally at a textile machine control unit. It is correspondingly advantageous for the textile machine if a level of reduced brightness and / or a level of increased brightness(s) and / or the type of modulating display of the indicators can be set centrally, in particular centrally at a textile machine control unit. This makes it possible, for example, to adjust the brightness of the displays to the respective lighting conditions at the location of the textile machines without having to go to each individual workstation. Likewise, the type of modulating display can be adapted to the environment so that the light signal is easily perceptible.Types of modulating displays include pulsating, rising and falling, fading in, fading out, flashing or other time-modulating light signals.

[0024] According to an initial implementation, it is conceivable to adjust all displays at the workstations of the textile machines together with a single setting.

[0025] According to another embodiment, however, it is advantageous if the level of reduced brightness(s) and / or the level of increased brightness(s) and / or the type of modulating display of the indicators can be set area by area or be adjustable on the textile machine. For example, such area-by-area adjustment can be made lengthwise or section by section. This allows, for instance, lengthwise sides or areas / sections facing windows or light sources to be set to a lower brightness, while areas of the textile machine facing away from windows or light sources can be set to a higher brightness. This adjustment can preferably be made centrally, particularly centrally at a textile machine control unit. However, an adjustment option can also be provided within each individual section or lengthwise side.

[0026] According to a further explanation, it is equally advantageous if the level of reduced brightness(s) and / or the level of increased brightness(s) and / or the type of modulating display are set centrally for each workstation. This allows for individual adjustment of each workstation, for example, to compensate for specific factors at the workstation location. For instance, the displays of certain workstations that are shaded by components of the textile machine or adjacent machines can be set to a higher brightness, or a modulating display can be additionally or alternatively configured for these workstations.

[0027] Following a further development of the method, the reduced brightness and / or increased brightness levels of the displays are preferably adjusted at each workstation to achieve a uniform brightness across the textile machine's displays. For example, newly installed displays with a higher luminance than those already in place can be set to a slightly lower brightness to compensate for the higher brightness or to match the brightness of the existing displays. This allows operators to clearly identify the workstations requiring attention. Alternatively, the brightness of the existing displays can be increased slightly to match the brightness of the newly installed displays.Furthermore, in order to achieve a uniform brightness of the displays on a textile machine, it is also possible to illuminate individual, especially newer, displays somewhat less brightly and to set other displays, which have been installed for a longer time, somewhat brighter.

[0028] To ensure uniform brightness across all displays on a textile machine, it is particularly advantageous to set a reduced brightness level and / or an increased brightness level at each individual workstation. This allows for comparison with neighboring workstations, facilitating a more precise adjustment of the brightness. A combination of central and individual settings is also possible. For example, the workstations could be centrally placed into a setting mode, displaying a corresponding menu on the respective workstation's display where the setting can be adjusted. However, it can also be beneficial to configure the type of modulating display at each individual workstation.

[0029] It is also advantageous if the color temperature of the display can be set, especially centrally, preferably at a textile machine control unit. This also allows the customer to centrally adjust the color temperature to the conditions of the production facility or to individual preferences.

[0030] It is also advantageous if the color temperature of the display indicators can be adjusted area by area, particularly by side and / or section, or by workstation. This allows the color temperature to be adapted to the specific conditions of certain areas of the textile machine. This adjustment can preferably be made centrally, particularly at a textile machine control unit. However, an adjustment option can also be provided within each individual section or side, or even at each individual workstation.

[0031] It is particularly advantageous if the color temperature is adjusted depending on the operating status of the workstation, the type of operator intervention required, and / or the operator's required qualifications. This allows the operating personnel to receive additional information about the workstation beyond the operational requirements, or to address specific personnel with particular qualifications.

[0032] It is also advantageous if the level of reduced brightness and / or increased brightness(s) and / or the color temperature of the display and / or the type of modulating display is automatically set or adjustable on the textile machine. For example, the level of reduced brightness and / or increased brightness is automatically increased as the display ages, or the color temperature is automatically adjusted as the display ages. This can be done automatically by the control device, such as the central textile machine control or a control device at the individual workstation.

[0033] In textile machines, it is advantageous if the color temperature of the display indicators is adjustable, particularly centrally, preferably at a textile machine control unit. The color temperature of the display indicators is preferably adjustable by area, especially by longitudinal side and / or section, or by workstation. However, an adjustment option can also be provided within each individual section or longitudinal side, or even at each individual workstation.

[0034] Furthermore, it is advantageous for the textile machine and the process if the displays have multiple display areas whose brightness and / or color temperature can be adjusted independently. For example, a display area that indicates the batch type using a color code could be illuminated at a constant brightness or excluded from the brightness reduction. This way, regardless of the state of the workstation, it is always clear which batch is being produced there.

[0035] Further advantages of the invention are described in the following exemplary embodiments. These show: Fig. 1 A cross-coil-producing textile machine in a schematic front view as an overview representation, Fig. 2 a display of a workstation of a textile machine with reduced brightness, Fig. 3 a display of a display of a workstation of a textile machine with increased brightness, Fig. 4 a display of a display of a workstation of a textile machine with a reduced brightness according to an alternative design, Fig. 5 a display of a display of a workstation of a textile machine with increased brightness according to an alternative design, Fig. 6. A display showing a workstation of a textile machine with increased brightness according to a further, alternative design. Fig. 7. A display showing a workstation display of a textile machine with increased brightness according to a further, alternative design, as well as Fig. 8 A textile machine with operator stations in a schematic front view.

[0036] In the following description of the figures, the same reference symbols are used for features that are identical and / or at least comparable in the various figures. The individual features, their design, and / or mode of operation are usually only explained in detail upon their first mention. If individual features are not explained again in detail, their design and / or mode of operation corresponds to the design and mode of operation of the already described features with the same or identical function. Furthermore, for the sake of clarity, often only one or a few of several identical components or features are labeled.

[0037] Fig. Figure 1 shows a cross-wound spool-producing textile machine 1 with a plurality of identical workstations 2 arranged side by side in a schematic front view. The workstations 2 are arranged between two frames 11 and are, in this case, divided into sections 10 in a manner known per se. Each section 10 comprises a specific number of workstations 2, which are structurally grouped together within the section 10. In this case, four workstations 2 are grouped together in each section. In reality, however, a section 10 contains many more workstations, and a section 10 typically includes workstations 2 on both longitudinal sides of the textile machine 1. Each workstation 2 has a delivery device 3 for supplying a thread 6 and a winding device 4 for winding the thread 6 onto a cross-wound spool 7.At each of the workstations 2, a graphic display 8 is arranged, which can display information about the respective workstation 2 in text and / or symbol form.

[0038] Furthermore, the textile machine 1 has at least one control device 9 by means of which a current display 12 (see Fig. 2-7) of the display 8 of a workstation 2 can be controlled. Only a central control device 9 of the textile machine 1 is shown here. The central control device 9 of the textile machine 1 can, in principle, also control the display indicators 12 of all workstations 2 of the textile machine 1. This is particularly possible if the central control device 9 of the textile machine 1 also controls the working elements of the workstations 2. This is also possible if the central control device 9 of the textile machine 1 receives the corresponding information to be displayed on the display 8 from a workstation-specific control device 9 (not shown here).

[0039] However, particularly in modern textile machines 1, at least some of the working elements of the workstations 2 can be individually controlled or driven for each workstation 2. In this case, each of the workstations 2 preferably has its own control device 9, which communicates with the central control device 9 of the textile machines 1. In this case, the workstation-specific control device 9 preferably also controls the current display 12 (see Fig. 2-7) of the workplace display.

[0040] The textile machine 1 shown here is designed as a spinning machine and accordingly has a spinning device 5 as a delivery device 3. Preferably, the textile machine 1 is designed as a rotor spinning machine and accordingly has an open-end rotor spinning device as a spinning device 5. However, the textile machine 1 could also be designed as an air-jet spinning machine, a friction spinning machine, or a winding machine.

[0041] Furthermore, according to the embodiment shown here, each workstation 2 is assigned a display 8. However, it would also be possible to assign a common display 8 to two or more workstations 2.

[0042] In such a textile machine 1, it is now proposed that the brightness of the display 12 be adjusted depending on the operating state of the workstation 2 by means of the control device, which can be either the central control device 9 of the textile machine 1 or a workstation-specific control device 9. This will be explained below using the Fig. 2 and Fig. 3 described.

[0043] Fig. 2 shows a display 12 of a display 8 of a workstation 2 (see. Fig. 1) a textile machine 1 (see Fig. 1) with reduced brightness. In the example shown, the brightness of display 12 is reduced, but the luminance is still high enough that the information on display 12 is still recognizable. Such a reduced brightness is set at workstations 2 that do not require operation, i.e., those that are in regular operating mode, in standby mode, or that are switched off or defective.

[0044] Contrary to the illustration shown, it is also possible to reduce the brightness of display 12 to such an extent that the information on display 12 is no longer visible, or even to reduce the brightness of display 12 to zero, so that display 8 is completely dark or appears inactive.

[0045] Display 12 includes a symbol that clearly communicates the operating status of workstation 2 to the operator. In this case, a smiling smiley face indicates the normal operating status. Display 12 also includes a button 13, which an operator can press to retrieve further information about workstation 2. A display area 14 is provided in the upper section of display 12, showing information about the application currently being produced at the workstation. It should be understood that this display configuration is for illustrative purposes only. Display 12 could also contain only text elements or exclusively graphic symbols. Likewise, more or fewer buttons 13 and separate display areas 14 could be provided.

[0046] Fig. Figure 3, in contrast, shows a display 12 of a display 8 at a workstation 2 of a textile machine 1 with increased brightness. Increased brightness is set at a workstation 2 when it requires operation. In this case, the brightness of display 12 is increased to such an extent that the information on display 12 is easily legible and the brightness of display 12 provides a clear contrast to other display 12s set at reduced brightness. This allows the operator to quickly identify, even from a distance, which of the workstations 2 currently require operation and to select them accordingly.

[0047] According to the present display 12, the need for operation is symbolized not only by the increased brightness, but also by a sad smiley face.

[0048] Fig. Figure 4 shows a display 12 of a display 8 of a workstation 2 of a textile machine 1 with reduced brightness according to an alternative version. In contrast to the version of the Fig. In addition to the graphic symbol, display 12 also contains text information about the operating status of the respective workstation 2. According to the present example, the textile machine 1 is configured as a spinning machine, so display 12 contains spinning information, which is generally described here as "Spinning information 1" and "Spinning information 2". This spinning information can include, for example, the rotational speeds of spinning elements, the delivery speed, or other operating parameters.

[0049] Fig. Figure 5 shows a display 12 of a display 8 of a workstation 2 of a textile machine 1 with increased brightness according to a further, alternative version, whereby the increased brightness again indicates a need for operation. In contrast to the version of Fig. In addition to the graphic symbol, display 12 contains text information about the current operating requirement. This text information is described generally as "Operator information" and may include details about the type of operating requirement, such as "Yarn alarm", "Technical alarm", or "Regular operating request".

[0050] This allows the operating personnel, upon arrival at the relevant workstation 2, to immediately identify the type of operating requirement and assess which tasks need to be performed. If necessary, the type of task to be performed can also be indirectly displayed to the operating personnel as "operator information." This can further accelerate the processing of operating requirements.

[0051] Fig. Figure 6 shows a display 12 of a display 8 of a workstation 2 of a textile machine 1 with increased brightness according to a further, alternative version. In contrast to the version of the Fig. In step 5, the operating personnel are provided not only with textual information but also with graphical information. In this example, the operating personnel are informed that they must perform manual rotor cleaning. This allows the operating personnel to understand what they need to do, regardless of the language.

[0052] It goes without saying that the statements of the Fig. 2-7 are merely examples and numerous variations are possible with regard to the graphic and textual information.

[0053] After an initial setup, the increased brightness, indicating a need for operation, can remain set for a predetermined, preferably adjustable, period of time. After the predetermined period has elapsed, the control device 9 automatically reduces the brightness or dims the display 8 again.

[0054] Fig. Figure 7 shows a display 12 of a display 8 at workstation 2 of a textile machine 1 with increased brightness according to a further, alternative configuration. In this configuration, the operator can acknowledge the operation performed by pressing a button 13. This acknowledgment can simultaneously signal the end of the operation to the control device 9, which then restores the reduced brightness at workstation 2.

[0055] Similarly, the increased brightness can also be triggered by the operator's own intervention, for example, if an operator performs an intervention at workstation 2 that had not previously indicated a need for intervention. In this case, too, the increased brightness can remain set for a predetermined period and then automatically revert to the reduced brightness.

[0056] As mentioned previously, both increasing and decreasing the brightness can be delayed or signaled by a light, such as fade-in, fade-out, or flashing. This allows operators to receive additional information about the operational status of the workstation, the type of intervention required, or the qualifications of any additional personnel.

[0057] Fig. Figure 8 shows a schematic front view of a textile machine 1 with operator workstations 2. It is evident that two of the workstations 2 have brightly lit displays, while the remaining workstations 2 have a reduced display brightness 12. On a real textile machine 1, this allows the operator to identify the operator workstations 2 from a distance.

[0058] In the inventive method and textile machine 1, only the displays 8 of workstations 2 requiring operation are brightly illuminated, while the displays 8 of workstations 2 not requiring operation are dimmed. This allows the operating personnel to optimally and quickly identify necessary interventions. Operating processes can thus be accelerated and machine efficiency increased. Furthermore, the service life of the displays 8 can be extended.

[0059] In the textile machine 1, it is particularly preferred if the brightness of the display 12 can be adjusted centrally, for example at the central control device 9. To compensate for varying lighting conditions at the location, it is particularly advantageous if the brightness of the display 12 of the individual displays 8 can be adjusted centrally, or at least area by area. For uniform illuminance across the entire textile machine 1, a central adjustment option that also allows for individual spinning station adjustments is advantageous.

[0060] In the examples shown, the marking of workstations requiring operation (2) was indicated by increased brightness. However, it is also possible, analogous to the previously described examples, to set a modulating display for the corresponding screen at these workstations (2).

[0061] The present invention is not limited to the embodiments shown and described. Modifications within the scope of the claims are also possible.
