Description

Technical Field

[0001] This invention relates to a textile machine for manufacturing cross-wound bobbins, having a plurality of identical, adjacent workstations and at least one operating device movable along these workstations to operate and / or maintain each workstation. The at least one operating device has at least one camera. The textile machine for manufacturing cross-wound bobbins also has at least one control unit for controlling the operating device. The invention also relates to a method for operating such a textile machine for manufacturing cross-wound bobbins. Background Technology

[0002] At textile machines that manufacture cross-wound bobbins, various operational activities are required at different workstations at regular intervals. These activities include, for example, replacing bobbins or reconnecting thread ends after production interruptions (such as thread breakage or cleaning steps). Similarly, some cleaning work may also be required at the workstations, or replacement of used template material. On manual machines, these activities must be performed by the operator, while on fully automatic machines, and in some cases, on semi-automatic machines, movable operating devices are provided.

[0003] To perform operational activities, operating equipment typically has multiple maintenance mechanisms. These mechanisms are usually controlled collaboratively by the operating equipment's control unit and the textile machine's control unit and / or the control units of each workstation, so that the operational activities can be precisely synchronized with the processes at each workstation. Furthermore, it is necessary to position the operating equipment used to perform the operational activities at each workstation as precisely as possible.

[0004] In the prior art, various methods are known for positioning movable operating equipment at textile machines and individual workstations. For example, DE 10 2004 035 261 A1 describes workstations emitting individual workstation identification signals. These workstation identification signals can be recorded by the operating equipment as it passes by. For this purpose, the operating equipment has a data transmission device. By recording the workstation identification signals and correspondingly adding or subtracting the number of received workstation identification signals, the operating equipment can determine its position based on its initial position, and thus determine the position of the workstation to be operated.

[0005] DE 101 36 598A1 also describes a method for precisely positioning an operating device at a workstation to be operated. For this purpose, a transmitter and a sensor are positioned at the operating device, and a reflector cooperating with them is also positioned at the workstation. For example, the transmitter is designed as a laser that can send a focused laser beam to the workstation. This laser beam is reflected back by the reflector and detected by the sensor. Based on the focused laser beam, the operating device can be positioned very precisely at the corresponding workstation.

[0006] As known from EP 2 304 086 B1, the operating equipment is equipped with a camera. Using the camera, images of the operating equipment and / or components of the workstation can be generated. These images can be processed by the control unit of the textile machine to determine the position of the operating equipment. The information obtained in this way can be used to locate and control the operating equipment. Similarly, the state of the workstation can be inferred from the images, for example, by analyzing the position of certain components of the workstation.

[0007] As also known from EP 3 754 064 A1, production parameters are checked at each workstation. The results of the check can be displayed by signal units, particularly LEDs, installed at each workstation via light signals. The light signals can include different colors, brightness, or flashing. According to one embodiment, a maintenance device with an optical detection mechanism can also be installed, which is located at the workstation via light signals. Summary of the Invention

[0008] The objective of this invention is to provide a method for operating a textile machine with operating equipment for manufacturing cross-wound drums, and a corresponding textile machine for manufacturing cross-wound drums, which enables simple and flexible control of the operating equipment.

[0009] This task is achieved through the features of the independent claims.

[0010] A textile machine for manufacturing cross-wound bobbins has multiple identical, adjacent workstations and at least one operating device that can move along these workstations to operate and / or maintain each workstation. The at least one operating device has at least one camera. The textile machine for manufacturing cross-wound bobbins also has at least one control unit for controlling the operating device.

[0011] This paper proposes assigning a graphic display to at least one workstation, through which information about these workstations can be displayed. Images of the display can be generated by a camera, and these images can be recorded and / or processed by at least one control unit of the textile machine that manufactures cross-wound bobbins, so that the information of the graphic display can be used to control the operating equipment.

[0012] Similarly, in a corresponding method for operating such a textile machine for manufacturing cross-wound bobbins, it is proposed to assign a graphic display to at least one of these stations, through which information about these stations is displayed, images of the display are generated by a camera of the operating equipment, these images are recorded and / or processed by the control unit of the textile machine for manufacturing cross-wound bobbins, and the information from the graphic display is used to control the operating equipment.

[0013] Such a graphic display can provide different types of information about these workstations. This information can be permanently stored in the control unit of the display and / or the control unit of the textile machine that manufactures cross-wound bobbins. In this case, this information includes immutable machine data, such as fixed points used to position the operating equipment at the textile machine that manufactures cross-wound bobbins. However, this information can also include variable data, especially operating data and / or status data for each workstation. This data can be provided, for example, by the control unit or sensors at the workstation, and is generally presented at the workstation in any case. In this case, the operating equipment can also be made to perform certain specific actions at the workstation using this data.

[0014] Within the scope of this application, in its simplest case, a graphic display is understood as a display element capable of displaying at least 2x2 pixels. In particular, the term "graphic display" includes screens using common technologies such as LCD screens, OLED screens, or electronic paper.

[0015] What is particularly advantageous in any situation is that different types of information can be provided via displays, depending on requirements or the current situation, because the display is variable. Therefore, it is not necessary to have a display at every workstation. For example, if the display is only used for roughly locating the operating equipment at a textile machine manufacturing cross-winding bobbins, it is sufficient to have displays only at certain reference locations or synchronization points. Similarly, image processing is not always necessary (e.g., for image recognition). In some cases, simply recording the presence and number of displays is sufficient.

[0016] However, preferably, each of these workstations is equipped with a graphic display through which information about the respective workstation can be displayed. In this method, a graphic display is correspondingly assigned to each of these workstations. Two or more workstations may also share a single display. Such displays are also frequently used in fully automated textile machines that manufacture cross-wound bobbins, so that operators can easily obtain information about the workstations, such as production data or malfunctions. If these displays are used as described to control the operating equipment, whether at several points or at each workstation, other arrangements for positioning the operating equipment, such as synchronization tracks, can be eliminated.

[0017] According to the first embodiment, the graphic display can show at least information about the number of the corresponding workstation, or display information about the corresponding workstation on the graphic display. For example, the number of each workstation can be directly displayed on the display, so that the operating equipment can clearly and directly identify the workstation. This can be achieved by the operating equipment or its control unit calculating the number of displays recorded as it passes by based on a reference position and thereby determining its position on the textile machine. In this case, not only the number but any other display can be used to identify the workstation. In this case, it is sufficient to use the control unit to record the presence of the displays.

[0018] Alternatively, the image on the display can be processed to directly determine the corresponding workstation number. This processing may also be performed on the display for control purposes once the operating equipment is positioned in front of a specific workstation, to compensate for "counting errors" in the operating equipment.

[0019] According to an advantageous improvement of the invention, information about the status of a corresponding workstation can be displayed on the graphic display. In this method, information about the status of the corresponding workstation, which is recorded by the operating device, is displayed on the graphic display. For example, these displays include at least "normal operation" and "fault" statuses.

[0020] The camera on the operating equipment can check the display as it passes by, and the control unit processes this information to determine whether action is needed at the relevant workstation. However, the display processing can only occur when the operating equipment is already positioned in front of a specific workstation. In this case, the operating equipment will be dispatched to the workstation requiring maintenance via the machine's own bus system in a known manner. Then, only the display processing will be performed to ensure that the operating equipment is actually positioned in front of the workstation requiring maintenance.

[0021] Also advantageously, information regarding maintenance requirements, particularly the operational activities currently to be performed by the operating equipment, can be displayed on a graphic display at the corresponding workstation or during the process. These displays can only include the status "Maintenance Requirement." In this case, the operating equipment can learn the specific operational activities to be performed through the bus system of the textile machine that manufactures the cross-wound bobbins. However, it is preferable to directly display the activity currently to be performed by the operating equipment. Thus, after processing by the control unit, the operating equipment can directly determine which actions are required at the relevant workstation. Since the maintenance requirements are displayed in the form of clear instructions, it is not necessary to photograph and record the posture of the components at the spinning position to determine the type of maintenance requirement from the specific layout of the spinning position. Furthermore, it is particularly advantageous to reduce the load on the bus system of the textile machine that manufactures the cross-wound bobbins, because the type of operational activity and (if any) information about the implementation of the operational activity can be "read" directly on the display by the operating equipment's camera.

[0022] In this method, it is also advantageous that the operating device is located at the textile machine manufacturing cross-wound bobbins and / or at one of these workstations based on recorded information regarding the station numbers and / or status and / or maintenance requirements. At the textile machine manufacturing cross-wound bobbins, the at least one operating device can be located accordingly based on information from one or more graphic displays at the textile machine manufacturing cross-wound bobbins and / or at one of the workstations of the textile machine manufacturing cross-wound bobbins. As mentioned above, the display display does not require processing; recording and counting may suffice. However, it is also possible, of course, to process the display display as the machine passes by. In both cases, the operating device can be located at the textile machine manufacturing cross-wound bobbins.

[0023] Furthermore, based on information displayed on the monitor and recorded by the operating device, the operating device is prompted by the control unit to continue moving or positioning itself before and / or to perform operational activities at one of these workstations. Therefore, the movement of the operating device can also be controlled via the monitor. The maintenance device can patrol along the workstations and intervene immediately upon determining a maintenance need at one of the workstations by processing the monitor display. Alternatively, the operating device can be dispatched to the workstation requiring operation via a bus system. En route to the workstation, the operating device can check its position at the textile machine manufacturing cross-winding bobbins according to the monitor display and ensure it is positioned at the correct workstation. The operating device can then read out what activities are being performed there. In this case, the execution of the operational activities is triggered after the control unit of the textile machine manufacturing cross-winding bobbins processes the monitor display.

[0024] According to another embodiment, this embodiment can supplement or replace the display of numbers, status, and maintenance requirements. Reference marks for positioning the operating equipment at the textile machine manufacturing cross-winding drum can be displayed graphically (or, if multiple displays are used), or during the process. In some cases, such reference marks are needed for reference travel at the start of the operating equipment's movement. Once the reference travel of the operating equipment is complete, the display can be used to show other information.

[0025] Another advantage is that a graphic display can show positioning marks used to precisely locate the operating equipment at the relevant workstation. Precise positioning ensures that the operating equipment is not only positioned in front of the correct workstation, but also that its maintenance mechanism is correctly positioned opposite the workstation. For example, after identifying the status of the workstation, the display can show positioning marks to simplify the final positioning.

[0026] However, workstation positioning does not necessarily have to be based on positioning markers. Positioning can also be done directly based on information displayed on the monitor. For example, certain rows in a graphical display can also be used as positioning markers.

[0027] Another advantage is that the installation tolerances from the display to the workstation and / or from the camera to the operating device are compensated when the operating device is positioned at the workstation. This can be achieved, for example, by determining the tolerances for each workstation and / or operating device after the final installation of the textile machine manufacturing the cross-winding drum. The tolerances can then be taken into account when controlling the travel movement of the operating device used to position it at the workstation. Additionally or alternatively, information about the corresponding workstation, especially the positioning mark, can also be displayed on the display in a manner offset from the determined display tolerance value.

[0041] In the following description of the accompanying drawings, identical or comparable features are referred to by the same reference numerals. Therefore, certain features are explained only upon their first mention or only once in accordance with the appropriate drawings. If these features are not further explained in conjunction with other drawings, their design and / or mode of operation correspond to the design and mode of operation of the same or similar features described. Furthermore, for clarity, when multiple identical features or components are present in a single drawing, only one or more of these identical features are designated. Detailed Implementation

[0042] Figure 1 A schematic front view of a textile machine 1 for manufacturing cross-wound bobbins is shown. The textile machine 1 for manufacturing cross-wound bobbins is designed as an automatic or semi-automatic textile machine 1 and has multiple identical, adjacently arranged workstations 2 between two machine bases 8. Each of these workstations 2 has a conveying device 3, a traction device 9 for drawing 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 production. If the textile machine 1 for manufacturing cross-wound bobbins is designed as a spinning machine, the conveying device 3 is a spinning device, such as a rotor spinning device or an air-jet spinning device. If the textile machine 1 for manufacturing cross-wound bobbins is designed as a winding machine, the conveying device is an unwinding bobbin or a spinning tube. In the case of a winding machine, unlike the figure shown, the traction device 9 is not absolutely necessary. According to embodiments of the textile machine 1 for manufacturing cross-wound bobbins, other components, such as working mechanisms and handling mechanisms, may also be arranged at the workstations 2. For example, a waxing device 15 at each workstation 2 can also be seen in this figure. Figure 2 , Figure 11 and Figure 12 The different stations 2 of the textile machine 1 that manufacture cross-wound drums are shown in detail from the side view.

[0043] Furthermore, a display 12 is provided at each workstation 2, which can display various information about these workstations 2. As an alternative to the illustrated scheme, it is also conceivable to allocate one display 12 to every two or several workstations 2. According to another embodiment (not shown here), the displays 12 may also be arranged only at certain locations on the textile machine 1 that manufactures cross-wound bobbins. Information about the respective workstations 2 can be displayed via the displays 12.

[0044] Sometimes, two different operational activities must be performed at the workstation. These activities include, for example, replacing a full bobbin 10 with an empty one, connecting yarn 6 after a production (joining or splicing) interruption, and various cleaning tasks. For example, in a rotor spinning machine, the spinning rotor 17 must be cleaned regularly (see...). Figure 2 For this purpose, the textile machine that manufactures the cross-wound drum has an operating device 5 that can move along the station 2. The operating device 5 has one or more maintenance mechanisms 16 that perform operating activities at the station 2 and therefore must be positioned very precisely relative to the corresponding station 2.

[0045] To control the functions of the textile machine 1 that manufactures cross-wound bobbins, the textile machine 1 has a central control unit 11, which is currently located in one of the machine bases 8. The control unit 11 can cooperate with the station control devices (not shown) of each workstation 2. The textile machine 1 that manufactures cross-wound bobbins may also have another control unit 11, which is located in the operating device 5 and connected to the central control unit 11. The control unit 11 of the operating device (if in this case, cooperating with the central control unit 11) controls the movement and operation of the operating device 5. Alternatively, this can also be done directly by the central control unit 11 of the textile machine 1 that manufactures cross-wound bobbins.

[0046] 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 the images from the camera. Alternatively, this can also be done directly by the central control unit 11 of the textile machine 1 that manufactures the cross-winding drum.

[0047] Figure 2A schematic side view shows a station 2 of a textile machine 1 that manufactures cross-wound bobbins. In this case, the textile machine 1 that manufactures cross-wound bobbins is designed as a free-end rotor spinning machine and therefore has a spinning device with a spinning rotor 17 as a conveying device 3. In a manner known per se, the fibrous material is fed into the spinning device via a feed roller 19 and a carding roller 18. The spun yarn 6 is then drawn by a traction device 9, and in this case, guided through a waxing device 15 and finally fed into a winding device 4, where the yarn is wound onto a bobbin 10. Here, a display 12 can also be seen at station 2. Similarly, a control unit 11 can also be seen, which may be the central control unit 11 of the textile machine 1 or a control unit 11 belonging to a station. Of course, each station 2 may also have a control unit 11 belonging to that station, which is connected to the central control unit 11 of the textile machine 1.

[0048] on the other hand, Figure 11 A station 2 of a textile machine 1 that manufactures cross-wound bobbins is shown in a schematic side view. This machine is designed as an air-jet spinning machine. In this case, the textile machine 1 has an air-jet spinning device 3 with spinning nozzles 22 as a conveying device. The fibrous material is fed into the spinning device via a drawing frame 23 in the same known manner. The spun yarn 6 is drawn by a drawing device 9. A waxing device 15 is also shown here, but it is not absolutely necessary. The yarn 6 continues to be fed into a winding device 4 and wound onto a bobbin 10. Regarding the control unit 11 also shown, as applicable in the rotor spinning machine described above, it can be either the central control unit 11 of the textile machine 1 or a station-specific control unit 11 connected to the central control unit 11 of the textile machine 1. Furthermore, station 2 also has a display 12.

[0049] In a similar way, finally Figure 12 A station 2 of a textile machine 1 for manufacturing cross-wound bobbins is also shown in a schematic side view. This machine is designed as a winding machine. In this case, the conveying device 3 contains a spinning tube wound with the yarn 6 to be rewound. The yarn 6 is drawn by a winding device 4 and then wound onto the bobbin 10. In its yarn path, the yarn 6 from the spinning tube passes sequentially through an air-cushion 24, a yarn tensioner 25, and a waxing device 15 (if present, but not shown here). Furthermore, a splicer 26 is arranged at station 2 for joining the yarn 6 after a breakage or cleaning step. Similarly, a control unit 11 is also shown here, which could be designed as a station-specific control unit or as a central control unit 11 of the textile machine 1. Also, a display 12 is arranged at station 2.

[0050] The setup is now as follows: the operating device 5 is controlled based on information provided on the display 12. For this purpose, at least one piece of information can be displayed on the display 12, based on which the movement of the operating device 5 can be controlled and / or the operating device 5 can be positioned on the textile machine 1 that manufactures cross-wound bobbins or at a specific station 2, and / or the operational activities of the operating device 5 can be controlled at one of the stations 2 based on this information. For this purpose, the camera 7 captures images on the display, and these images are then recorded at least by the operating device 5 and / or the control unit 11 of the textile machine 1 that manufactures cross-wound bobbins. If necessary, these images can be processed in more detail, so that the operating device can also identify, based on the information on the graphic display 12, whether an operational activity needs to be performed at station 2 and (if so) which operational activities need to be performed. Advantageously, information can be transmitted directly from the display 12 to the operating device 5 via the camera 7, thereby reducing the load on the communication system or bus system (not shown) of the textile machine 1 that manufactures cross-wound bobbins.

[0051] This information may include information about the number of the corresponding workstation 2. Figure 3 A detailed view of three adjacent workstations 2 is shown, each with a display 12. The number of each workstation 2 is displayed as plain text on the display 12. This display can be recorded as an image by the camera 7 of the operating device 5 and processed by the control unit 11 and / or central control unit 11 of the operating device 5. This display can be used to determine the position of the operating device 5 at the textile machine 1 that manufactures cross-wound bobbins. For this purpose, the operating device 5 can continuously read and process the display on the display 12 as it travels past. This eliminates the need for reference travel. Alternatively, the operating device 5 can determine its position at the textile machine 1 that manufactures cross-wound bobbins simply by counting the number of recorded displays based on a reference position. Once the operating device 5 is positioned at a specific workstation 2, the display can be processed for control purposes, as errors can sometimes occur during reference travel and / or counting. The number of the workstation 2 can also only be displayed temporarily. For example, after the operating device 5 is positioned, the display can be changed and show the state of the workstation 2 (see...). Figures 4 to 6 Similarly, the display 12 can also display the specific operating instructions of the operating device 5, which can be directly read.

[0052] Figures 4 to 6 An exemplary display of the status of station 2 is shown. These displays are only temporarily displayed when the operating device 5 has been positioned in front of station 2. Alternatively, these displays can also be displayed from the beginning and recorded and processed as the operating device 5 passes by. As another alternative, only the number of displays can be recorded as it passes by in order to determine the position of the operating device 5 at the textile machine 1 that manufactures the cross-winding bobbins.

[0053] Figure 4The display 12 shows the "normal operation" status. This display can be shown if station 2 is in normal production and there are no operational activities waiting to be processed. If the operating equipment 5 records the display as it passes by and processes it directly, the display can cause the operating equipment 5 to continue moving, and (if this is the case) counts station 2 for positioning purposes.

[0054] Figure 5 The display 12 shows a "Maintenance Required" status. This display can be shown if workstation 2 is not currently in production and an operational activity is needed. Alternatively, the display can be shown when workstation 2 is still in production but soon requires maintenance intervention. If the display is processed directly as the operating equipment 5 passes by, it can position the operating equipment 5 in front of the relevant workstation 2 so that operational activities can be performed there.

[0055] Figure 6 The display on monitor 12 shows a "fault" status. This display can be shown if workstation 2 is not currently in production, and the problem cannot be resolved by operating equipment 5 and operator intervention, or (if so) requires intervention from another operating equipment 5. This display can prompt operating equipment 5 to proceed to the relevant workstation 2 or to summon the operator or another operating equipment 5.

[0056] Figure 7 The display shows the first operational activity that needs to be performed, in this case, changing the yarn bobbin. Maintenance requests are only made when operating device 5 is dispatched to the workstation or when it is recorded while passing by (see...). Figure 5 The display can only be shown after the device is positioned in front of workstation 2. Alternatively, the display can be shown 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 operation to be performed at the workstation. The display can enable the operating device 5 to position itself at the relevant workstation 2 and / or perform the displayed operation at workstation 2.

[0057] In a similar way, Figure 8 A display shows the need for rotor cleaning at the rotor spinning machine. It goes without saying that, depending on the type and implementation of the spinning machine 1 that manufactures the cross-wound bobbins, other cleaning activities may also be displayed. Furthermore, Figure 7 The implementation method also applies here.

[0058] Figure 9Reference mark 13 is shown. The reference mark is necessary when the operating device 5 determines its position at the textile machine 1 manufacturing cross-wound bobbins based on the reference position by counting stations 2. For this purpose, the operating device 5 performs a reference drive when the machine starts, 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. Displays 12 are arranged at at least at these reference positions, and reference mark 13 is displayed on the displays at least during the reference drive of the operating device 5. After the reference drive is completed, the operating device 5 can determine its position by counting stations 2. Furthermore, after the reference drive is completed, the displays can show additional information about stations 2.

[0059] Figure 10 A diagram showing the display of positioning mark 14 is illustrated. The positioning mark can be displayed on display 12 to make it easier for the operating device 5 to finally position itself at workstation 2. Preferably, the display is shown only if the operating device 5 has already recognized a previous display requiring maintenance, which has been processed, and the operating device 5 has information about the specific operational activity to be performed. In the current case, positioning mark 14 is displayed as a crosshair. With the aid of camera 7 and control unit 11, the operating device 5 can accurately position itself at workstation 2 by comparing the captured image with a stored image, displaying the stored image when correctly positioned.

[0060] All displays are shown in the form of graphic symbol 20. Figures 4 to 10 However, in principle, it can also be displayed as text and read using camera 7. Furthermore, in Figures 4 to 10 Additional display panels 21 can also be seen on the display 12. These display panels can display other information that the operator can read. Similarly, some display panels 21 can also be designed as buttons, so that the operator can also access various other information on the display 12 and (if in this case) make input.

[0061] Therefore, both the operator and the operating device 5 can "read" these display screens. Thus, a separate information device for the operating device 5 is unnecessary. Furthermore, the operating device 5 can immediately check the success or failure of the operation after it has been performed. For example, if the display on monitor 12 changes to "normal operation" after the operation has been performed, the success of the operation can be inferred from this. Alternatively, the success of the operation can also (if this is the case) be displayed through another display that can be directly "read" by the camera 7.

[0062] As a supplement or alternative to displaying the status in the form of graphic symbols 21, the status of the corresponding workstation 2 can also be displayed by the backlight color of the display 12. For example, green indicates "normal operation" and red indicates "fault". This can also be identified by the camera 7 of the operating device 5.

[0063] This invention is not limited to the embodiments shown. Even though different embodiments are shown and described, variations and combinations of various features within the scope of the patent claims are equally possible.
