Description

The present invention relates to a cross-wound bobbin-producing textile machine with a large number of similar work stations arranged next to one another and with at least one operating device that can be moved along the work stations for operating and/or maintaining the individual work stations. The at least one operating device has at least one camera. The textile machine that produces cross-wound bobbins also has at least one control unit for controlling the operating device. Furthermore, the invention relates to a method for operating such a cheese-making textile machine.

On textile machines that produce cross-wound bobbins, it is regularly necessary to carry out various operating activities at the individual work stations. These include, for example, changing a bobbin or reconnecting a thread end after an interruption in production, for example a thread break or a clearing cut. It may also be necessary to carry out certain cleaning work at the workplace or to exchange template material that has run out. While these activities have to be carried out by an operator on manual machines, a movable operating device is provided on fully automatic and sometimes also on semi-automatic machines.

In order to carry out the operating activities, this usually has several maintenance units, which are usually controlled by a control unit of the operating device in cooperation with a control unit of the textile machine and/or a control unit of the individual work station, in order to adjust the operating activities exactly to the processes at the work station to be able to carry out. Furthermore, it is necessary to position the operating device for the execution of the operating activities as precisely as possible at the individual work stations.

Various methods have become known in the prior art for positioning a movable operating device on the textile machine and at the individual work stations. For example, in the DE 10 2004 035 261 A1 described that the jobs each broadcast individual job identifiers. These can be detected by the operating device when driving past. For this purpose, the operating device has a data transmission device. By detecting the job identifiers and correspondingly adding or subtracting the number of received job identifiers, starting from a basic position, the operating device can determine its position and thus also the position of the job that needs to be operated.

From the DE 101 36 598 A1 a method for fine positioning of an operating device at the work station to be operated is also described. For this purpose, an emitter and a sensor are provided on the operating device and also a reflector on the work site that interacts with them. The emitter is designed as a laser, for example, which sends a bundled laser beam to the work site. The laser beam is reflected by the reflector and detected by the sensor. Due to the bundled laser beam, the operating device can be positioned very precisely at the respective work site.

From the EP 2 304 086 B1 it is known to equip an operating device with a camera. Using the camera, it is possible to generate images of components of the operating device and/or the work stations. These can be evaluated by a control unit of the textile machine, as a result of which the position of the operating device can also be determined. The information obtained in this way can be used to position and control the operating device. It is also possible to deduce the status of the work site from images of the work site, for example by evaluating the position of certain components of the work site.

From the EP 3 754 064 A1 it is also known to check production key figures at the individual workplaces. The result or results of the check can be displayed by means of light signals by means of signal units, in particular LEDs, arranged at the individual work stations. The light signals can include different colors, brightness or flashing. According to one embodiment, a maintenance device with an optical detection device can also be provided, which positions itself at the work locations by means of the light signals.

The object of the present invention is to propose a method for operating a cheese-making textile machine with an operating device and a corresponding cheese-making textile machine that allow simple and flexible control of the operating device.

The object is solved with the features of the independent claims.

A textile machine that produces cross-wound bobbins has a large number of similar work stations arranged next to one another and at least one operator that can be moved along the work stations equipment for the operation and/or maintenance of the individual work stations. The at least one operating device has at least one camera. Furthermore, the textile machine producing cross-wound bobbins has at least one control unit for controlling the operating device.

It is proposed that at least one of the work stations be assigned a graphic display, by means of which information about the work station can be displayed, that images of the display can be generated by means of the camera and that the images can be recorded and/or evaluated by the at least one control unit of the textile machine producing cross-wound bobbins are, so that the information of the graphic display can be used to control the operating device.

Likewise, in a corresponding method for operating such a textile machine that produces cheeses, it is proposed that at least one of the work stations is assigned a graphic display, by means of which information about the work station is displayed, that images of the display are generated by means of the camera of the operating device, that the images are a control unit of the textile machine producing cross-wound bobbins is recorded and/or evaluated and that the information from the graphic display is used to control the operating device.

Such a graphic display can be used to provide a wide variety of information about the jobs. This information can be permanently stored in a control device of the display and/or a control device of the textile machine producing cross-wound bobbins. In this case, the information includes unchangeable machine data, for example fixed points for positioning the operating device on the textile machine producing cross-wound bobbins. However, the information can also include variable data, in particular operating data and/or status data of the individual work stations. These can be provided, for example, by a control device or by sensors at the work site and are usually available at the work sites anyway. In this case, the data can also be used to prompt the operating device to carry out specific actions at the work stations.

In the context of the present application, a graphic display is understood in the simplest case as a display element that can display at least 2×2 pixels. In particular, the term "graphic display" includes screens with common technologies such as LCD screens, OLED screens or e-paper.

In any case, it is particularly advantageous that different types of information can be provided by means of the display, depending on requirements or current circumstances, since the display of the display can be changed. It is therefore not absolutely necessary to provide a display at every work station. If, for example, the display is only used for the rough positioning of the operating device on the textile machine producing cross-wound bobbins, it would be sufficient to provide a display only at certain reference positions or synchronization points. Likewise, it is not always necessary to evaluate the images, for example by image recognition. In some cases it is sufficient to simply record the presence and number of displays.

However, each of the jobs is preferably assigned a graphic display, by means of which information about the respective job can be displayed. In the process, a graphic display is assigned to each of the work stations accordingly. It is also possible for two or more workstations to share one display each. Such displays are also often used on fully automatic cross-wound bobbin-producing textile machines in order to make information about the work stations, such as production data or faults, easily accessible to an operator. If these displays are used as described to control the operating device, whether only at a few points or at every work station, then other arrangements for positioning the operating device, such as synchronization rails and the like, can be omitted.

According to a first embodiment, at least information about a number of the respective job can be displayed by means of the graphic display, or information about a number of the respective job is displayed on the graphic display. For example, the number of the individual job can be shown directly on the display, so that the operating device can identify the job clearly and directly. This can already be done in that the operating device or its control unit counts the number of displays detected while driving past, starting from a reference position, and can determine its position on the textile machine from this. In this case, not only the number but also any other display could be used to identify the jobs. In this case, it is sufficient to use the control unit to detect the presence of a display.

Alternatively, the image of the display could also be evaluated to determine the number of the respective job to be determined directly. Such an evaluation of the display could also be carried out for control purposes as soon as the operating device is positioned in front of a specific work station in order to compensate for “counting errors” in the operating device.

According to an advantageous development of the invention, information about a status of the respective work station can be displayed by means of the graphic display. In the method, information about a status of the respective work station, which is recorded by the operating device, is shown on the graphic display. For example, the displays include at least the states “normal operation” and “malfunction”.

The camera of the operating device can check the display as it drives past and, after evaluation by the control unit, deduce whether an action is required at the relevant work station. However, the display could also only be evaluated when the operating device is already positioned in front of a specific work station. In this case, the operating device would be ordered to the work station requiring maintenance in a manner known per se via a machine-specific bus system. The display evaluation would then only take place in order to ensure that the operating device is actually positioned in front of the work area requiring maintenance.

It is also advantageous if the graphic display can be used to display information about a maintenance requirement, in particular about an operating activity currently to be carried out by the operating device, at the respective work location or is displayed on the graphic display during the process. The display can only include the status "maintenance required". In this case, the operator control device can be informed of the actual operating activity to be carried out via the bus system of the textile machine producing cross-wound bobbins. However, the activity currently to be carried out by the operating device is preferably displayed directly. After evaluation by the control unit, the operating device can thus directly derive which actions are required at the relevant work station. Since the maintenance requirement is displayed in the form of a clear instruction, it is not necessary to record the position of components at the spinning position in order to determine the type of maintenance requirement from a specific constellation at the spinning position. It is also particularly advantageous that the bus system of the textile machine producing cheeses can be relieved in this way, since the information about the type of operating activity and possibly also about the success of the operating activity can be "read" directly on the display by the camera of the operating device .

In the method, it is also advantageous if the operating device is positioned on the textile machine producing cheeses and/or at one of the work stations using the recorded information about the number and/or the condition and/or the need for maintenance of the work stations. In the case of the textile machine producing cheeses, the at least one operating device can be positioned on the textile machine producing cheeses and/or at one of the work stations of the textile machine producing cheeses using the information from the or more graphic displays. As mentioned, it can be sufficient to record and count the displays without evaluation. Of course, the displays can also be evaluated while driving past. In both cases, the operating device can be positioned on the textile machine producing cross-wound bobbins.

Furthermore, it is advantageous if, depending on the information shown on the display and recorded by the operating device, the operating device is prompted by the control unit to either continue driving or to position itself in front of one of the work stations and/or to carry out an operating activity at the respective work station. The movement of the operating device can thus also be controlled by means of the displays. The maintenance facility can patrol along the work sites and intervene as soon as it determines by evaluating the display that there is a need for maintenance at one of the work sites. Alternatively, the operating device can be ordered via the bus system to a work station that requires operation. On its way to the work station, the operating device can check its position on the textile machine producing cross-wound bobbins using the display and ensure that it is positioned at the correct work station. Then she can read which activities are to be carried out there. In this case, the execution of the operating activity is triggered after evaluation of the display by the control unit of the textile machine producing cross-wound bobbins.

According to another embodiment, which is possible in addition or as an alternative to the display of numbers, states and maintenance requirements, the graphic display (or, if there are several displays, using at least one of the displays) is a reference mark for positioning the operating device on the cross-wound bobbin manufacturing Textile machine can be displayed or a reference mark is displayed in the process. Such a reference mark is required in some cases for a referencing run at the beginning of the movement of the operating device. As soon as the homing run of the operating device is completed, the display can then be used to display other information.

In addition, it is advantageous if a positioning mark for fine positioning of the operating device at the work location in question can be displayed or is displayed by means of the graphic display. Fine positioning can be used to ensure that the operating device is not only positioned in front of the correct work site, but is also positioned at the work site in such a way that the maintenance elements of the operating device are correctly positioned opposite the work site. For example, after recognizing the status of the job, the display could show the positioning mark to simplify the final positioning.

However, positioning at a work site does not necessarily have to be based on a positioning mark. The positioning can also be done directly based on the information shown on the display. For example, certain lines of a graphic display can also serve as positioning marks.

When positioning the operating device at a work site, it is also advantageous if mounting tolerances of the display to the work site and/or the camera to the operating device are compensated for. This can be done, for example, by determining the tolerances for each work station and/or operating device after the final assembly of the textile machine producing cross-wound bobbins. The tolerances can then be taken into account when controlling the travel movement of the operating device for positioning at the work site. Additionally or alternatively, the information about the respective job, in particular the positioning mark, can be shown on the display offset by the tolerance value determined on the display.

In the following description of the figures, the same reference symbols are used for identical or comparable features. Some of the features are therefore only explained when they are first mentioned or only once using a suitable figure. If these features are not explained separately again in connection with the other figures, their design and/or mode of action corresponds to the design and mode of action of the identical or comparable features described. For reasons of clarity, if there are several identical features or components in one figure, only one or only a few of these identical features are labeled.

1 shows a schematic front view of a textile machine 1 that produces cheeses. Each of the work stations 2 has a delivery device 3 , a take-off device 9 for removing a thread 6 and a winding device 4 for winding the thread 6 onto a bobbin 10 . The delivery device 3 delivers the thread 6 during the production process. If the textile machine 1 producing cheeses is designed as a spinning machine, the delivery device 3 is a spinning device, for example a rotor spinning device or an air spinning device. If the textile machine 1 producing cross-wound bobbins is designed as a winding machine, the delivery device is a pay-off bobbin or a spinning cop. In the case of a winding machine, in contrast to the illustration shown, a take-off device 9 is not absolutely necessary. Depending on the design of the textile machine 1 producing cross-wound bobbins, other components such as working elements and handling elements can also be arranged at the work stations 2 . For example, a paraffining device 15 can be seen at each of the work stations 2 in the present illustration. The 2 , 11 and 12 each show work stations 2 of different cross-wound bobbin-manufacturing textile machines 1 in detail in a side view.

Furthermore, a display 12 is provided at each of the jobs 2, which can display various information about the jobs 2. As an alternative to the representation shown, it is also conceivable for two or more work stations 2 to be jointly assigned a display 12 . According to a further embodiment, not shown here, it is also possible for a display 12 to be arranged only at certain points of the textile machine 1 producing cross-wound bobbins. Information about the respective job 2 can be displayed by means of the display 12 .

From time to time, 2 different operating activities have to be carried out at the work stations. These include, for example, replacing a full bobbin 10 with an empty tube, connecting the thread 6 after an interruption in production (piecing or splicing) and various cleaning work. For example, with a rotor spinning machine it is necessary to regularly rotate the spinning rotor 17 (see 2 ) to clean. For this purpose, the textile machine producing cross-wound bobbins has an operating device 5 that can be moved along the work stations 2 . The operating device 5 has one or more maintenance units 16 which carry out the operating activities at the work stations 2 and must therefore be positioned very precisely in relation to the respective work station 2 .

To control the functions of the textile machine 1 producing cheeses, the textile machine 1 producing cheeses has a central control unit 11 which is arranged in one of the frames 8 in the present case. The control unit 11 can interact with work station controls (not shown) of the individual work stations 2 . The textile machine 1 producing cross-wound bobbins can also have a further control unit 11 which is arranged in the operating device 5 and is connected to the central control unit 11 . The control unit 11 of the operating device controls, possibly in cooperation with the central control unit 11, the travel movement and the operating activities of the operating device 5. Alternatively, it is also possible for this to be carried out directly by the central control unit 11 of the textile machine 1 producing cross-wound bobbins.

The operating device 5 also has at least one camera 7 . In the example shown here, the camera 7 is connected to the control unit 11 of the operating device 5 so that it can capture and evaluate the images from the camera. Alternatively, this could also be done directly by the central control unit 11 of the textile machine 1 producing cross-wound bobbins.

2 shows a work station 2 of such a cross-wound-producing textile machine 1 in a schematic side view. The textile machine 1 producing cross-wound bobbins is in the present case designed as an open-end rotor spinning machine and therefore has a spinning device with a spinning rotor 17 as the delivery device 3 . A fiber material is fed to the spinning device in a manner known per se via a feed roller 19 and an opening roller 18 . The finished spun thread 6 is then drawn off by means of a take-off device 9, in the present case guided over a waxing device 15 and finally fed to the winding device 4, where it is wound onto a spool 10. Again, a display 12 at the work station 2 can be seen. A control unit 11 can also be seen, which can be both the central control unit 11 of the textile machine 1 and a workstation-specific control unit 11. Of course, each of the workstations 2 can also have a workstation-specific control unit 11, which is connected to the central control unit 11 of the textile machine 1 connected.

11 shows, however, a work station 2 of a cheese-making textile machine 1, which is designed as an air-jet spinning machine, in a schematic side view. In this case, the textile machine 1 has an air spinning device with a spinneret 22 as the delivery device 3 . A fiber material is fed to the spinning device via a drafting system 23 in a manner that is also known. The finished spun thread 6 is drawn off by means of a draw-off device 9 . A paraffining device 15 is also shown here, but this is not absolutely necessary. The thread 6 continues to be fed to the winding device 4 and wound onto a spool 10 . With regard to the control unit 11 that is also shown, as in the rotor spinning machine described above, it applies that this can be both the central control unit 11 of the textile machine 1 and a workstation-specific control unit 11, which is connected to the central control unit 11 of the textile machine 1. The work station 2 also has a display 12 .

Similarly shows 12 Finally, a work station 2 of a cross-wound bobbin-producing textile machine 1, which is designed as a winding machine, in a schematic side view. In this case, the delivery device 3 contains a spinning cop wound with a thread 6 to be rewound. The thread 6 is drawn off by means of the winding device 4 and then wound onto a spool 10 . In its yarn path, the yarn 6 coming from the spinning cop successively passes through a balloon limiter 24, a yarn tensioner 25 and, if necessary, a paraffining device 15, which, however, is not shown here. At the work station 2 there is also a splicer 26 for connecting the thread 6 after a thread break or a cleaner cut. A control unit 11 is also shown here, which can be configured both as a control unit 11 of the work station and as a central control unit 11 of the textile machine 1 . A display 12 is also arranged here at the work station 2 .

It is now provided to control the operating device 5 based on information provided on the display 12 . For this purpose, at least one piece of information can be shown on display 12, which can be used to control the travel movement of the operating device 5 and/or to position the operating device 5 on the textile machine 1 producing cheeses or at a specific work station 2 and/or based on which an operating activity of the operating device 5 can be controlled at one of the jobs 2. For this purpose, the camera 7 takes pictures of the display, which are then at least recorded by the control unit 11 of the operating device 5 and/or the textile machine 1 producing cheeses. The images can also be evaluated in more detail, if necessary, so that the operating device can also use the information on the graphic display 12 to identify whether and, if so, which operating activities are to be carried out at the work station 2 . It is advantageous that information can be transmitted directly from the display 12 to the operating device 5 via the camera 7, whereby a communication system or bus system (not shown) of the textile machine 1 producing cheeses can be relieved.

The information can contain information about a number of the respective job 2 . 3 shows a detailed view of three jobs 2 arranged next to one another, each with a display 12. The number of the respective job 2 is shown in plain text on the display 12. This display can be captured as an image by the camera 7 of the operating device 5 and evaluated by the control unit 11 of the operating device 5 and/or the central control unit 11 . The display can be used to determine the position of the operating device 5 on the textile machine 1 producing cross-wound bobbins. For this purpose, the operating device 5 can constantly read and evaluate the indications on the displays 12 as it drives past. A reference run is then not required. Alternatively, starting from a reference position, the operating device 5 can only count the number of recorded displays and from this determine its position on the textile machine 1 producing cross-wound bobbins. An evaluation of the display can then take place for control purposes as soon as the operating device 5 is positioned in front of a specific work station 2, since errors can occasionally occur during the referencing run and/or the count. The number of job 2 can also only be displayed temporarily. For example, after the operating device 5 has been positioned, the display could change and show a status of the work station 2 (see Fig. 4 - 6 ). Likewise, the display 12 could also show specific instructions for the operating device 5, which can be read by this directly.

The 4 - 6 show examples of displays of states of a job 2. These can only be displayed temporarily if an operating device 5 has positioned itself in front of a job 2. Alternatively, these displays can also be displayed from the outset and recorded and evaluated while the operating device 5 is driving past. As a further alternative, only the number of displays can be recorded when driving past, in order to determine the position of the operating device 5 on the textile machine 1 producing cross-wound bobbins.

4 shows an indication of the display 12 for the status "normal operation". This can be displayed if workstation 2 is producing regularly and no operator activities are pending. If the operating device 5 detects the display as it drives past and this is evaluated directly, this display can cause the operating device 5 to continue driving and possibly, if necessary for positioning purposes, to count the work location 2 .

5 shows an indication of the display 12 for the status "maintenance required". This can be displayed if workplace 2 is not currently producing because operator activities are required. Alternatively, the display can already be displayed when work station 2 is still producing, but requires maintenance intervention shortly. If the display is evaluated directly when the operating device 5 is driven past, this display can cause the operating device 5 to position itself in front of the relevant work station 2 in order to carry out an operating activity there.

6 shows an indication of the display 12 for the "fault" status. This can be displayed if the work station 2 is not currently producing because problems could not be eliminated by the operating device 5 and operator intervention or, if necessary, the intervention of another operating device 5 is required. This display can cause the operator control device 5 to drive past the relevant work station 2 or to summon an operator or another operator control device 5 .

The 7 shows a display of a need to carry out a first operating activity, here a bobbin change. This display can only be displayed when the operating device 5 is positioned in front of the work station 2, after it has been ordered there or when driving past a maintenance requirement (see 5 ) has registered. Alternatively, the ad can also be displayed directly without any previous ad. After evaluation by one of the control units 11, the operating device 5 can use the camera 7 to “read” the actual operating activity to be carried out at this work location. This display can cause the operating device 5 to position itself at the relevant work station 2 and/or to carry out the displayed operating activity at the work station 2 .

Similarly, the 8th a display of a need to carry out rotor cleaning on a rotor spinning machine. It goes without saying that, depending on the type and design of the textile machine 1 producing cross-wound bobbins, other cleaning activities could also be displayed. Otherwise, the statements are correct 7 here too.

9 shows a display of a reference mark 13. This is required when the operating device 5 determines its position on the cross-bobbin-producing textile machine 1 by counting the work stations 2 starting from a reference position. For this purpose, the operating device 5 carries out a referencing run when the machine is started, after a power failure or after a loss of its reference position. For example, at least two, preferably three, reference positions can be provided on a longitudinal side of the textile machine 1 . A display 12 is arranged at least at these reference positions, on which the reference mark 13 is displayed at least during the reference travel of the operating device 5 . After completion of the homing run, the operating device 5 can then determine its position by counting the work stations 2 . Furthermore, after the referencing run is complete, the display can show other information about job 2.

10 shows a representation of a display of a positioning mark 14. This can be shown on the display 12 in order to make the final positioning in front of the work site 2 easier for the operating device 5. This display is preferably only shown when the operating device 5 has recognized a previous display of a maintenance requirement, this has been evaluated and the operating device 5 has the information about the specific operating activity to be carried out. In the present case, a crosshair is shown as the positioning mark 14 . By means of the camera 7 and the control unit(s) 11, the operating device 5 can position itself exactly at the work site 2 by comparing the recorded image with a stored image, which shows the display with correct positioning.

In the 4 - 10 all displays are shown in the form of graphic symbols 20. In principle, however, it would also be possible to display this as text and to read it using the camera 7 . Furthermore, in the 4 - 10 further display fields 21 can be seen. These can show further information which can be read by operating personnel. Likewise, some display fields 21 can also be designed as buttons, so that an operator can also call up various other information on the display 12 and, if necessary, can also make entries.

The display can thus be “read” both by operating personnel and by the operating device 5 . As a result, separate information devices for the operating device 5 are not required. It is also advantageous that the operating device 5 can immediately check the success or failure of the measure after performing an operating activity. If, for example, the display 12 changes to “normal operation” after the operating activity has been carried out, the success of the operating activity can be inferred from this. Alternatively, the success of the operating activity can also be indicated by a further display, which can be “read” directly by the camera 7 .

In addition or as an alternative to displaying the states in the form of graphic symbols 21, the state of the respective work station 2 could also be indicated by a color of the backlighting of the display 12. For example, the color green could indicate the "normal operation" status and the color red the "malfunction" status. This could also be recognized by the camera 7 of the operating device 5 .

The invention is not limited to the exemplary embodiments shown. modifications within the scope of the patent claims are just as possible as a combination of the features, even if they are shown and described in different exemplary embodiments.
