Description

Textile machine for producing cross-wound bobbins and method for operating such a textile machine

Technical Field

The invention relates to a textile machine for producing cross-wound bobbins, comprising a plurality of identical stations arranged next to one another and at least one operating device which can be moved along the stations for operating and/or maintaining the individual stations. The at least one operating device has at least one camera. The textile machine for producing the cross-wound bobbins also has at least one control unit for controlling the operating devices. The invention also relates to a method for operating such a textile machine for producing cross-wound bobbins.

Background

At textile machines that produce cross-wound bobbins, various operating activities need to be performed at various stations on a timed basis. These operational activities include, for example, replacement of bobbins or reconnection of lugs after production breaks (e.g., wire breaks or cleaning steps). Also, it may be desirable to perform some cleaning work at the station or to replace spent template material. On manual machines, these activities have to be performed by an operator, while on fully automatic machines, in some cases also semi-automatic machines, movable operating devices are provided.

In order to perform the operating activities, the operating device generally has a plurality of maintenance mechanisms, which are generally controlled by the control unit of the operating device in cooperation with the control unit of the textile machine and/or the control units of the individual stations, in order to enable the operating activities to be matched with the processes at the stations with a time-accurate degree. Furthermore, it is necessary to position the operating device for performing the operating activities at the individual stations as precisely as possible.

In the prior art, various methods are known for positioning movable handling devices at textile machines and at various stations. For example, DE 10 2004 035 261 A1 describes that the stations each issue a separate station identification signal. These station identification signals can be recorded by the operating device when driving through. For this purpose, the operating device has a data transmission device. The operation equipment can determine the position of the station based on the initial position by recording the station identification signals and correspondingly adding and subtracting the number of the received station identification signals, so as to determine the position of the station to be operated.

DE 101 36,598 a1 also describes a method for precisely positioning an operating device at a station to be operated. For this purpose, transmitters and sensors are provided at the operating device and reflectors cooperating therewith are also provided at the workstation. For example, the emitter is designed as a laser that can send a focused laser beam to the workstation. The laser beam is reflected back by the reflector and detected by the sensor. Depending on the focused laser beam, the handling device can be positioned very precisely at the corresponding station.

The operating device is known from EP 2 304,108 B1 to be equipped with a camera. Using a camera, an image of the components of the operating device and/or the workstation may be generated. These images can be processed by the control unit of the textile machine, so that the position of the operating device can be determined. The information obtained in this way can be used for locating and controlling the operating device. Likewise, the status of a workstation may also be inferred from an image of the workstation, such as by analyzing the location of certain components of the workstation.

It is also known from EP 3 754 064 A1 to check production parameters at various stations. The result of the inspection can be displayed by means of optical signals by means of signal units, in particular LEDs, which are arranged at the individual stations. The light signals may comprise different colors, brightnesses or flashes. According to one embodiment, a maintenance device with an optical detection device can also be provided, which is positioned at the workstation by means of an optical signal.

Disclosure of Invention

The object of the invention is to provide a method for operating a textile machine for producing cross-wound bobbins with an operating device and a corresponding textile machine for producing cross-wound bobbins, which enables simple and flexible control of the operating device.

This object is achieved by the features of the independent claims.

The textile machine for producing the cross-wound bobbins has a plurality of identical stations arranged next to one another and at least one operating device movable along these stations for operating and/or maintaining the individual stations. The at least one operating device has at least one camera. The textile machine for producing the cross-wound bobbins also has at least one control unit for controlling the operating devices.

It is proposed that at least one station is assigned a graphic display by means of which information about the stations can be displayed, that images of the display can be generated by means of the camera and can be recorded and/or processed by at least one control unit of the textile machine that produces the cross-wound bobbin, so that the information of the graphic display can be used for controlling the operating device.

In a corresponding method for operating a textile machine for producing crosswound bobbins, it is likewise proposed to assign a graphic display to at least one of the stations, to display information about the stations via the graphic display, to generate images of the display via a camera of the operating device, to record and/or process the images by a control unit of the textile machine for producing crosswound bobbins, and to use the information of the graphic display for controlling the operating device.

Different types of information about the stations can be provided by such a graphic display. Such information may be permanently stored in the control means of the display and/or in the control means of the textile machine that makes the cross-wound bobbin. In this case, the information includes immutable machine data, for example, fixed points for positioning the operating device at the textile machine that manufactured the cross-wound bobbin. However, this information may also include variable data, in particular operational data and/or status data of the individual stations. Such data may be provided, for example, by sensors controlling the device or the station and are usually present at the station anyway. In this case, the operating device can also be caused to perform certain specific actions at the workstation by means of these data.

Within the scope of the present application, a graphic display is understood in the simplest case as a display element which can display at least 2x2 pixels. In particular, the term "graphic display" includes screens with general technology, such as LCD screens, OLED screens or electronic paper.

In any case, it is particularly advantageous that different types of information can be provided by the display, as the display is variable, depending on the requirements or the current situation. Thus, it is not necessary to provide a display at each station. For example, if the display is only used for coarsely positioning the operating device at the textile machine that makes the cross-wound bobbin, it is sufficient to provide the display only at certain reference positions or synchronization points. Also, it is not always necessary to process the image (e.g., by image recognition). In some cases it is sufficient to record only the presence and number of displays.

Preferably, however, each of these stations is assigned a graphic display by means of which information about the respective station can be displayed. In this method, a graphic display is allocated to each of these stations accordingly. One display may also be shared every two or more stations. Such displays are also often used in fully automated textile machines for manufacturing cross-wound bobbins so that the operator can easily obtain information about the work stations, such as production data or malfunctions. If these displays are used as described for controlling the operating device, whether at only a few points or at each station, other arrangements for positioning the operating device, such as synchronization tracks or the like, can be dispensed with.

According to a first embodiment, at least information about the number of the respective station can be displayed by means of the graphic display or information about the respective station can be displayed on the graphic display. For example, the numbers of the individual stations may be displayed directly on the display, so that the operating device can clearly and directly identify the stations. This has been achieved by the operating device or its control unit calculating the number of displays recorded during the passage based on the reference position and determining the position thereof at the textile machine therefrom. In this case, not only the number but any other display may be used to identify the station. In this case it is sufficient to use the control unit to record the presence of the display.

Alternatively, the image of the display may also be processed in order to directly determine the number of the corresponding station. This processing of the display presentation for control purposes may also be performed once the operating device is positioned in front of a particular station to compensate for "counting errors" in the operating device.

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

The camera of the operating device can check the display when driving through and be processed by the control unit to derive whether the relevant station needs to take action. Likewise, the processing of the display presentation is only possible when the operating device is already positioned in front of a specific station. In this case, the operating device will be dispatched via the machine's own bus system to the station requiring maintenance in a manner known per se. Only the display process will then be performed to ensure that the operating equipment is actually positioned in front of the station requiring maintenance.

It is also advantageous if information about the maintenance requirements, in particular about the operating activities currently to be performed by the operating device, can be displayed on the graphic display at the respective station or in the process by means of the graphic display. These displays can only include the status "maintenance need". In this case, the operating device is informed of the specific operating activity to be performed by the bus system of the textile machine that makes the cross-wound bobbin. However, it is preferable to directly display the activity currently to be performed by the operation device. Thus, the operating device, after processing by the control unit, can directly derive which actions are required at the relevant stations. Since the maintenance requirements are displayed in the form of clear instructions, it is not necessary to take a picture of the attitude of the recording assembly at the spinning position in order to determine the type of maintenance requirements from the specific layout of the spinning position. Furthermore, it is particularly advantageous if the load on the bus system of the textile machine that produces the cross-wound bobbins is reduced, since the information about the type of operating activity and, if this is the case, about the implementation of the operating activity can be "read" directly on the display by the camera of the operating device.

In this method, it is also advantageous if the operating device is positioned at the textile machine that makes the cross-wound packages and/or at one of the stations, according to the recorded information about the number and/or the status and/or the maintenance requirements of these stations. In the cross-wound bobbin-producing textile machine, the at least one operating device may be positioned accordingly in accordance with information of one or more graphic displays at the cross-wound bobbin-producing textile machine and/or at one of the stations of the cross-wound bobbin-producing textile machine. As described above, the display shows that no processing is required, and recording and counting may be sufficient. However, it is of course also possible to process the display during the drive-through. In both cases, the handling device may be positioned at the textile machine that makes the cross-wound bobbin.

It is also advantageous if the operating device is caused by the control unit to continue moving or to be positioned in front of one of the stations and/or to perform an operating action at the respective station, in dependence on the information displayed on the display and recorded by the operating device. Thus, the travelling movement of the operating device can also be controlled by the display. The maintenance device can be walked along the stations and it can intervene immediately by the processing display as soon as it is determined that a maintenance need exists at one of the stations. Alternatively, the operating device may be dispatched via a bus system to the workstation requiring operation. On its way to the station, the operating device can check its position at the textile machine where the cross-wound bobbin is manufactured, according to the display, and ensure that it is positioned at the correct station. The operating device can then read out which activities are performed there. In this case, the execution of the operating activity is triggered after the display is processed by the control unit of the textile machine that produces the cross-wound bobbin.

According to another embodiment, which may be in addition to or instead of the display of numbers, status and maintenance requirements, reference marks for positioning the operating device at the textile machine that makes the cross-wound bobbin may be displayed by a graphical display (or at least one display if there are multiple displays), or displayed in the process. In some cases, such a reference mark is required for reference travel at the start of the operation device travel movement. As soon as the reference travel of the operating device is completed, the display can be used to display other information.

It is also advantageous if positioning marks for fine positioning of the operating device at the relevant station can be displayed by means of a graphic display. By fine positioning it is ensured that the handling device is positioned not only in front of the correct station, but also at the station in such a way that the maintenance mechanism of the handling device is correctly located opposite the station. For example, after identifying the status of the station, the display may display positioning indicia to simplify the final positioning.

However, the positioning at the workstation does not necessarily have to be based on positioning marks. Positioning can also be performed directly from information displayed on the display. For example, certain lines of the graphical display may also be used as positioning marks.

It is also advantageous that the mounting tolerances of the display to the workstation and/or the camera to the operating device are compensated when positioning the operating device at the workstation. This can be achieved, for example, by determining the tolerances of each station and/or operating equipment after the final installation of the textile machine in which the cross-wound bobbin is manufactured. Tolerances may then be taken into account in controlling the travelling movement of the operating device for positioning at the station. In addition or alternatively, information about the respective station, in particular the positioning mark, can also be displayed on the display in a manner offset from the determined display tolerance value.

Detailed Description

Fig. 1 shows a schematic front view of a textile machine 1 for manufacturing cross-wound bobbins. The textile machine 1 for producing cross-wound bobbins is designed as an automatic or semiautomatic textile machine 1 and has a plurality of identical stations 2 arranged next to one another, which are arranged between two machine bases 8. Each of these stations 2 has a conveyor 3, a traction device 9 for drawing the yarn 6 and a winding device 4 for winding the yarn 6 onto a bobbin 10. The conveying device 3 conveys the yarn 6 during the production process. If the textile machine 1 for producing the cross-wound packages is designed as a spinning machine, the conveying device 3 is a spinning device, for example a rotor spinning device or an air jet spinning device. If the textile machine 1 for producing cross-wound bobbins is designed as a winder, the conveying device is an unwinding bobbin or a spinning tube. In the case of a winder, the pulling device 9 is not absolutely necessary, unlike the illustrated drawing. Other components, such as working and handling mechanisms, may also be arranged at station 2, depending on the embodiment of the textile machine 1 in which the cross-wound bobbin is manufactured. For example, in the present illustration, it is also possible to see the waxing device 15 at each station 2. Fig. 2, 11 and 12 each show in side view a detail of a different station 2 of the textile machine 1 for producing cross-wound bobbins.

Furthermore, at each station 2 a display 12 is provided which can display various information about these stations 2. As an alternative to the illustration shown, it is also conceivable to assign a display 12 jointly for every two or every few stations 2. According to another embodiment (not shown here), the display 12 may also be arranged only in certain positions of the textile machine 1 where the cross-wound packages are manufactured. Information about the respective station 2 can be displayed by means of the display 12.

Sometimes 2 different operational activities must be performed at the workstation. These operational activities include, for example, replacement of the full bobbin 10 with an empty tube, joining the yarn 6 after interruption of production (joining or splicing), and various cleaning operations. For example, in a rotor spinning machine, the spinning rotor 17 must be cleaned regularly (see fig. 2). For this purpose, the textile machine for producing the cross-wound bobbins has an operating device 5 which can be moved along the station 2. The handling device 5 has one or more maintenance mechanisms 16 which perform handling activities at the stations 2 and must therefore be positioned very precisely with respect to the respective stations 2.

In order to control the functioning of the textile machine 1 that produces the cross-wound packages, the textile machine 1 that produces the cross-wound packages has a central control unit 11, which is arranged in one of the housings 8 in the present case. The control unit 11 may cooperate with a station control (not shown) of the respective stations 2. The textile machine 1 for 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 (in cooperation with the central control unit 11, if this is the case) controls the travelling movement and the operating activity of the operating device 5. Alternatively, this can also be done directly by the central control unit 11 of the textile machine 1 that produces the 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 the control unit can record and process images of the camera. Alternatively, this can also be done directly by the central control unit 11 of the textile machine 1 that produces the cross-wound bobbins.

Fig. 2 shows a schematic side view of a station 2 of such a textile machine 1 for producing cross-wound bobbins. In the present case, the textile machine 1 for producing the cross-wound packages is designed as an open-end rotor spinning machine and therefore has a spinning device with a spinning rotor 17 as the conveying device 3. In a manner known per se, the fibre material is fed to the spinning device via a feed roller 19 and a carding roller 18. The spun yarn 6 is then drawn by the drawing device 9, in the present case guided through the waxing device 15 and finally fed to the winding device 4, where it is wound onto the bobbin 10. Here, the display 12 can also be seen again at the station 2. Likewise, a control unit 11 can also be seen, which can be a central control unit 11 of the textile machine 1 or a control unit 11 belonging to a workstation. Of course, at each station 2 there may also be a control unit 11 belonging to the station, which is connected to the central control unit 11 of the textile machine 1.

Fig. 11, on the other hand, shows a schematic side view of one station 2 of a textile machine 1 for producing cross-wound bobbins, which is designed as an air jet spinning machine. In this case, the textile machine 1 has an air jet spinning device with a spinning nozzle 22 as the conveying device 3. The fibre material is fed to the spinning device by a drawing frame 23 in a manner known as such. The spun yarn 6 is drawn by a drawing device 9. Here, the waxing device 15 is also shown, but it is not absolutely necessary. The yarn 6 continues to be fed to the winding device 4 and wound onto the bobbin 10. As regards the control unit 11 shown as such, as is applicable in the above-mentioned rotor spinning machine, it can be either the central control unit 11 of the spinning machine 1 or the control unit 11 belonging to a workstation connected to the central control unit 11 of the spinning machine 1. In addition, station 2 has a display 12.

In a similar manner, fig. 12 finally shows, also in a schematic side view, one station 2 of a textile machine 1 for producing cross-wound bobbins, which is designed as a winder. In this case, the delivery device 3 comprises a textile tube around which the yarn 6 to be rewound is wound. The yarn 6 is drawn by the winding device 4 and then wound onto the bobbin 10. In its yarn path, the yarn 6 from the textile bobbin passes in turn through a balloon breaker 24, a yarn tensioner 25 and a waxing device 15 (as the case may be, but is not shown here). Furthermore, a splicer 26 is arranged at the station 2 for joining the yarns 6 after a thread break or cleaning step. Also shown here is a control unit 11, which can be designed as a control unit 11 belonging to a workstation or as a central control unit 11 of the textile machine 1. Also at station 2 is arranged a display 12.

The operating device 5 is now set up to be controlled in accordance with the information provided on the display 12. For this purpose, at least one message can be displayed on the display 12, on the basis of which the driving movement of the operating device 5 and/or the positioning of the operating device 5 at the textile machine 1 that produces the cross-wound bobbin or at a particular station 2 can be controlled, and/or on the basis of which the operating activity of the operating device 5 can be controlled at one of the stations 2. For this purpose, the camera 7 captures images of the display, which are then recorded at least by the operating device 5 and/or by the control unit 11 of the textile machine 1 that produces the cross-wound packages. These images can also be processed in more detail if necessary, so that the operating device can also identify, from the information on the graphic display 12, whether and, if this is the case, which operating activities are to be performed at the station 2. Advantageously, the information can be transmitted directly from the display 12 to the operating device 5 via the camera 7, whereby the load on the communication system or bus system (not shown) of the textile machine 1 that makes the cross-wound bobbin can be reduced.

Such information may contain information about the number of the corresponding station 2. Fig. 3 shows a detailed view of three stations 2 arranged next to each other, each station having a display 12. On the display 12, the number of each station 2 is displayed as plain text. The display may be recorded as an image by the camera 7 of the operating device 5 and processed by the control unit 11 and/or the central control unit 11 of the operating device 5. The display can be used to determine the position of the operating device 5 at the textile machine 1 where the cross-wound bobbin is manufactured. For this purpose, the operating device 5 can constantly read and process the display on the display 12 as it passes. Thus, no reference is needed to travel. Alternatively, the operating device 5 may count only the number of recorded displays based on the reference position and thereby determine its position at the textile machine 1 where the cross-wound bobbin is manufactured. Once the operating device 5 is positioned in front of a certain station 2, the display of the display can be processed for control purposes, since errors sometimes occur during the reference travel and/or counting. The number of the station 2 can also only be displayed temporarily. For example, after positioning of the operating device 5, the display can change and display the state of the station 2 (see fig. 4 to 6). Likewise, the display 12 may also display specific operating instructions of the operating device 5, which may be read directly.

Fig. 4 to 6 show exemplary displays of the state of the station 2. These displays can only be displayed temporarily when the operating device 5 has been positioned in front of the station 2. Alternatively, these displays can also be displayed from the beginning and recorded and processed as the operating device 5 passes. As a further alternative, it is possible to record only the number of displays displayed during the drive-through in order to determine the position of the operating device 5 at the textile machine 1 where the cross winding drum is manufactured.

Fig. 4 shows the display 12 in a "normal operation" state. This display may be displayed if station 2 is producing normally and there is no operational activity waiting for processing. If the operating device 5 registers to the display as it passes and processes it directly, the display can cause the operating device 5 to continue to move and (if this is the case) the stations 2 are counted as for positioning purposes.

Fig. 5 shows the display 12 in the "maintenance needed" state. This display may be displayed if station 2 is not currently being produced, in which case an operational activity is required. Alternatively, the display may already be displayed when station 2 is still in production, but maintenance interventions are required soon. If the display is processed directly as the operating device 5 passes, it may cause the operating device 5 to position itself in front of the relevant station 2 in order to perform an operating activity there.

Fig. 6 shows the display of the display 12 in a "fault" state. The display may be displayed if the station 2 is not currently being produced, in which case the problem cannot be eliminated by the intervention of the operating device 5 and the operator, or if this is the case, the intervention of another operating device 5 is required. The display may cause the operator 5 to drive through the relevant station 2 or call the operator or another operator 5.

Fig. 7 shows a display of the need to perform a first operational activity, here a replacement yarn package. This display can be displayed only when the operating device 5 is brought to the station or after the maintenance requirement (see fig. 5) has been recorded while driving through, positioned in front of the station 2. Alternatively, the display may be displayed directly without any prior display. After processing by one of the control units 11, the operating device 5 can use the camera 7 to "read" the specific operating activity to be performed at that station. The display may cause the operating device 5 to position itself in the relevant station 2 and/or to perform the displayed operating activity at the station 2.

In a similar manner, fig. 8 shows a display showing the need for rotor cleaning at the rotor spinning machine. It goes without saying that other cleaning activities may also be displayed, depending on the type and embodiment of the textile machine 1 from which the cross-wound packages are made. The embodiment of fig. 7 is also applicable here.

Fig. 9 shows a reference sign 13. The reference marks are necessary when the operating device 5 determines its position at the textile machine 1 where the cross-wound packages are manufactured by the counting station 2 based on the reference position. For this purpose, the operating device 5 performs a reference travel at the start-up of the machine, after a power failure or after losing its reference position. For example, at least two, preferably three reference positions can be provided on the longitudinal side of the textile machine 1. At least in these reference positions a display 12 is arranged on which reference marks 13 are displayed at least during the reference travel of the operating device 5. After the completion of the reference travel, the operating device 5 can determine its position by counting the stations 2. In addition, the display may display other information about station 2 after the completion of the reference travel.

Fig. 10 shows a diagram of a display of the positioning mark 14. Positioning indicia may be displayed on the display 12 to facilitate final positioning of the operating device 5 in front of the station 2. Preferably, the display is displayed only when the operating device 5 has identified a previous display requiring maintenance, which has been processed and the operating device 5 has information about the specific operating activity to be performed. In the present case, the positioning mark 14 is shown as a crosshair. By means of the camera 7 and the control unit 11, the operating device 5 can position itself accurately at the station 2 by comparing the captured image with the stored image, which is displayed when positioned correctly.

All of the displays are shown in figures 4 to 10 in the form of graphical symbols 20. In principle, however, it can also be displayed as text and read by means of the camera 7. Further display panels 21 can be seen in fig. 4 to 10. These display panels may display other more information that the operator can read. Likewise, some display panels 21 may also be designed as buttons so that the operator may also invoke various other information on the display 12 and, if so, also make inputs.

Thus, both the operator and the operating device 5 can "read" these display representations. Thus, a separate information device for operating the device 5 is not required. It is also advantageous that the operating device 5 can check the success or failure of a measure immediately after performing an operating activity. For example, if the display of the display 12 becomes "normal running" after the performance of the operational activity, the success of the operational activity may be inferred therefrom. Alternatively, the success of the operating activity may also be displayed (as the case may be) by a further display, which may be "read" directly by the camera 7.

In addition to or instead of displaying the status in the form of graphical symbols 21, the status of the respective stations 2 may also be displayed by the backlight color of the display 12. For example, green represents a "normal operation" state, and red represents a "failure" state. This can also be recognized by the camera 7 of the operating device 5.

The invention is not limited to the embodiments shown. Variations and combinations of the various features within the scope of the patent claims are equally possible, even if shown and described in the different embodiments.
