[0014] The invention is based on the objective of providing an operating device for a textile machine and a method for operating a textile machine that overcome at least certain disadvantages of the prior art. In particular, the invention is based on the objective of providing an operating device for a textile machine and a method for operating a textile machine that improves the flexibility of operating a textile machine.

[0015] This problem is solved by an operating device for a textile machine and a method for operating a textile machine with the features of the independent claims. Advantageous embodiments are described in the dependent claims.

[0016] An operating device for textile machines has a switching function for toggling the device between a basic mode and an expert mode. The basic mode provides a basic operating interface for basic operation of a textile machine by a user, and the expert mode provides an expert operating interface for expert operation of the textile machine by the user. The operating device has an authorization function for authorizing the user, and the switching function is configured to require user authorization before switching to expert mode. The operating device has a remote transmission function for operating a remote textile machine by the user. This remote transmission function is configured to establish a communication link to the remote textile machine for the user to operate it remotely.The control device features a remote receiving function for operating the textile machine from a remote user. This function is designed to receive a communication link from the remote control device, enabling the remote user to operate the textile machine. The control device allows for flexible operation of textile machines, whether a machine assigned to the device or a remote machine. Operation from a spinning mill control center or a mobile operating device is also possible. The ability to switch between a basic mode and an expert mode allows the control device to be adapted to the tasks of a user, which may differ, for example, between a shift supervisor and a regular operator. The basic mode is available without authorization.It enables both the operation of a remote textile machine and the operation of a textile machine by a remote user. The basic mode can include, for example, emergency or warning functions of the textile machines, while the expert mode can include functions for adjusting machine parameters. A spinning mill with a large number of textile machines can be equipped with a variety of such control devices to allow basic or expert operation of the mill's textile machines from each of these devices.

[0027] In one embodiment, the control device is designed to indicate whether it is switched to basic or expert mode and / or to indicate whether a communication connection exists from a remote control device. The user of the control device is thus informed about its operating status.

[0028] In one embodiment, the operating device is designed such that the setting of parameters of the textile machine is made available for operating the textile machine and / or the remote textile machine.

[0029] In one embodiment, the operating device is designed such that information about the textile machine and / or about the remote textile machine is provided for the operation of the textile machine, wherein the information includes in particular alarms and / or warning messages, in particular depending on whether the information relates to the textile machine or to the remote textile machine, and in particular further depending on whether the operating device is switched to basic mode or expert mode.

[0030] In a method for operating textile machines, an operating device is assigned to a textile machine. The operating device includes a switching function to toggle between a basic mode and an expert mode. The basic mode provides a basic operating interface for basic operation of the textile machine by a user, while the expert mode provides an expert operating interface for expert operation. The operating device also includes an authorization function to authorize the user, and the switching function is configured so that user authorization is required to switch to expert mode.The control device activates a remote transmit function for the user to operate a remote textile machine. This remote transmit function establishes a communication link to the remote textile machine for the user to operate it. The control device also activates a remote receive function for the user to operate the textile machine remotely. This remote receive function receives a communication link from the remote control device for the user to operate the textile machine.

[0031] In one embodiment, the remote transmission function is designed to establish the communication link to the remote textile machine via an operating device or a control device of the remote textile machine. Brief description of the characters

[0044] The operating data area 30 contains a display of operating data for ring spinning machine 1. Machine operating data can include key production figures such as the current production status (Machine Efficiency 31), production per hour or productivity (possibly related to a shift 32), quality status (Quality CV 33), mean time between assists (MTBA 34), etc. The classification of the operating data can be visually supported, for example, by colors and various symbols such as smileys, indicating whether the value is good, average, or not good. Operating data 31, 32, 33, and 34 can be displayed as user-selectable elements to show further information, such as the trend of the respective operating data over the last minutes, hours, or days.

[0045] The machine visualization area 40 contains a simplified representation 41 of the ring spinning machine 1, with visual status information about materials and ongoing processes; a recipe display 42 with information and, in particular, the name of the current recipe; several quick-access buttons 43, 44, 45 for tasks that the operator frequently has to perform; for example, handling material; quick access to functions; simple troubleshooting; simple cleaning of the machine; frequently recurring machine operations (e.g., ejecting the can, adding material...); setting, starting, and stopping production orders; etc.; a shift change button 46, which allows the operator to indicate which shift is active; and – in the case of notifications – notification icons that are displayed directly on the simplified representation 41 of the machine.

[0046] As mentioned, the basic operating mask 10 is according to Fig. 2This is displayed when the control device 9 has switched to basic mode. The control device 9 can be configured to switch to basic mode after a restart of the control device 9 or the ring spinning machine 1, or after a certain period of time without user interaction with the user interface.

[0047] Fig. 3Figure 10 schematically shows the basic operating screen with a warning message "Empty can is missing" in notification area 20. For clarity, a symbol is displayed, featuring an exclamation mark within a triangle. The message, which may be colored, includes the number "No. 1857" and indicates when it was displayed, "2 minutes ago". Simultaneously, a simplified representation 41 of the machine displays a warning indicator 50 (e.g., a colored triangle) indicating the machine location to which the warning message refers.

[0048] Fig. 4The diagram schematically shows the basic operating screen 10 with an alarm message 56, "Table Funnel Error," in notification area 20. For clearer visualization, a symbol is displayed, featuring a cross inside a circle. Alarm message 56 includes the number "No. 1745" and indicates when the message was displayed, "3 minutes ago." A service button 58 is activated in the header 11 for notifying and dispatching a service technician. A button 59 is activated in notification area 20 for simplified display of all notifications (if there are multiple notifications). Simultaneously, the machine display 41 includes an indicator 57 (e.g., a colored circle with a cross) to specify the machine location to which the alarm message refers.

[0049] Fig. 5The diagram schematically shows the operation of the toggle switch 17 to access the switching function for changing the operating device 9 from basic mode to expert mode. After pressing the toggle switch 17, the expert operating screen 70 is displayed in expert mode.

[0050] Switching from basic mode with the displayed basic operating screen 10 ("simple mode") to expert mode with the displayed expert operating screen 70 ("advanced mode") can be done without automatic login or authorization. All users can switch between modes at any time. However, only users with the necessary permissions can make changes to the machine settings. The operating device 9 may automatically prompt the user to authorize themselves if they wish to make a change (see...). Fig. 7When the user leaves the expert control screen 70 and returns to the basic control screen 10 or basic mode, the user's authorization is automatically reset or the user is automatically logged out. In one embodiment, the control device 9 also automatically returns to the basic control screen 10 or basic mode after a certain time (adjustable). The basic control screen 10, the expert control screen 70, and the entire visualization can advantageously be based on web technology (e.g., HTML5).

[0051] Fig. 6Figure 70 schematically depicts the expert control screen, which allows users to operate the T1 textile machine in expert mode. This screen provides access to more advanced settings and information than the basic control screen 10 offers in basic mode. The expert control screen 70 is designed for "experts," such as production experts, quality managers, service technicians, etc., and offers access to the machine's full functionality. It can also be referred to as "advanced mode." The expert control screen 70 is tailored to the tasks of an "expert," which include, for example: changing production settings, fine-tuning, machine optimization, quality management, complex problem solving, troubleshooting, shift organization, support, and software updates.

[0052] The expert control screen 70 comprises a header 80, a navigation bar 90, and a menu overview 100. The header 80 is always visible on the expert control screen 70. It contains only the information and functions necessary on every screen. A machine selection 81 includes information about the machine type, machine number, and the current time. A mode 82 displays the operating status and mode of the machine. The mode 82, such as "Manual," "Automatic," "Service," etc., can be changed here. Pressing the button displays a drop-down menu through which settings can be changed. A notification button 83 displays the most important notifications and provides direct access to a notification list (see below). Fig. 8The notifications can be different colors. A recipe button (84) displays the current recipe. Pressing the button opens a dropdown menu that allows you to change the following settings: save changes to a recipe; restore a recipe; save current machine settings as a new recipe; create new recipes; access the recipe list; etc. A help button (85), which may be identical to the help button (14) of the basic operating screen (10), can access: a help page that overlays the main screen; an operating manual; a function to take a screenshot of the page; etc. A language selection button (85) allows you to set the language of the user interface. An authorization button (87) allows you to authorize a user, such as logging in and out, switching users, and retrieving information about the current user.A toggle switch 88 enables the operation of the switching function of the control device 9 to switch from expert mode to basic mode.

[0053] The navigation bar 90 of the expert interface 70 always displays the user's exact current location within the application. It always contains at least the overview page of a main section, such as "Settings." As soon as the user navigates within a section, the next navigation level is displayed, and the parent level becomes active, allowing the user to return to the parent level with a single click. The menu overview 100 is directly accessible on the left, while forward and backward navigation buttons are located on the right.

[0054] A menu overview 100 provides access to standardized applications, which may have the following features. A settings button 1, "Settings," allows access to all machine settings, structured by machine module or process / task (e.g., "Can," "Drawing Machine," "Spinning Machine," "Combing Machine," etc.). Advanced settings can be shown or hidden depending on the user login level. A quality button 2, "Quality," allows access to quality-related information and settings (e.g., targets, tolerance levels). A data analysis button 3 allows access to information and analysis of ongoing production and trends, structured by topic (e.g., "Efficiency," "Energy"), with reporting capabilities. A notification button 4, "Notifications," allows access to a list of active notifications and a link to the notification history and analysis.A recipe button (5), "Recipes," provides access to a list of all saved recipes with management options (e.g., duplicate, delete, etc.). A service button (6), "Maintenance," provides access to commissioning / troubleshooting functions, such as I / O tests, sensors, manual functions, etc. A maintenance button (7), "Service," provides access to maintenance settings, pending tasks, history, etc. A general settings button (8), "General Settings," provides access to production-related settings and settings not directly related to production.These settings can be transferred between machines and may include: network settings; user management; moving settings; viewing settings; units and measures; time and date; language and keyboard; software and licensing; basic mode settings; lamp configuration (if available for this device); horn configuration (if available for this system); etc. A "User Manual" button (12) provides access to a complete user manual with search capabilities. A "Info & Logs" button (9) provides access to general information about the machine (e.g., operating hours) and detailed, filterable lists of all events logged on the device. A "Backup" button (10) provides access to various backup options.A data transfer button 11, "Data Transfer," provides data transfer options to / from the device, with a list of possible data records to be transferred. Note: General machine information (e.g., machine number) must always be included in a transfer to uniquely identify the data.

[0055] Fig. 7 A dialog box (105) is displayed for authorizing or logging in a user, prompting for a username and password. The device automatically prompts the user to log in when they wish to make a change. It is also possible for a user to log in to the machine using an RFID tag. User authorization can include assigning a permission level, with a shift supervisor potentially having a higher permission level than a regular machine operator.

[0056] Once a user has authorized themselves, this authorization can be revoked by pressing the authorization button 87, or the user can log out. If the user leaves the expert control screen 70 and returns to the basic control screen 10, they can be automatically logged out. After a specified period (configurable), the device can also automatically return to the basic control screen 10 or to basic mode. The control device can be configured to switch to basic mode after a machine restart or a power interruption.

[0057] Fig. 8This displays a list of 140 possible notifications, which include system-triggered messages to the user and appear when user interaction or information is required. There are three main types of notifications. Alarms are triggered by serious problems that may require or cause a machine shutdown. Warnings are triggered by problems that could lead to an alarm if no action is taken. Information refers to non-critical notifications that can inform the user about future intervention requirements.

[0058] The handling of notifications works similarly on both the basic operating screen 10 and the expert operating screen 70; only the level of detail varies. Notifications can be handled via four elements. The first element refers to an in-context notification symbol (e.g., a warning symbol on the machine model, see below). Fig. 2A click on the icon opens the notification details as an overlay. A second element refers to a notification button (83) in the header (80) displaying the latest or most important notification. Clicking this button opens the notification list (140). A third element refers to a notification list (140) containing all pending notifications requiring user intervention (i.e., alarms, warnings, maintenance). Clicking on any of these notifications opens a notification detail as an overlay. A fourth element displays a notification detail as an overlay with detailed information about the notification (e.g., an HTML excerpt from the user manual for this notification type), as well as troubleshooting options and direct access to the complete user manual.

[0059] The elements of the basic operating screen 10 and / or the expert operating screen 70 may depend on a user's authorization or permission level.
