[0032] The invention is now explained in more detail by means of several exemplary embodiments shown in the drawings, wherein the invention is not limited to the illustrations shown, in particular not to the structure and design of the systems.

[0041]
[0042] It should be stated by way of introduction that, in the individual embodiments, the same parts are provided with the same reference numbers or same component designations, wherein the disclosures contained in the entire description can, by analogy, be transferred to identical parts with identical reference numbers or identical component designations, respectively. The position details selected in the description, such as, e.g., top, bottom, lateral, etc., likewise relate to the figure described, and in the event of a change of position, they are to be transferred to the new position by analogy. Individual features or feature combinations from the exemplary embodiments shown and described may also represent independent inventive solutions.
[0043]
[0044] For example, it is possible that for the production of an injection-molded part 3 plastic granules or powder are fed to the processing machine 4 via a granule conveyor 9 and possibly via a metering device 11 or from a granule dryer 10. By means of a temperature control unit 13 and/or cooling unit, the injection mold 7 can be kept at operating temperature by feeding a temperature control medium, or heated or cooled accordingly, respectively, so that optimum processing of the plastic granules or powder, which must be plasticized for injection into the injection mold 7, is made possible.
[0045] In addition, the system can be equipped with a monitoring device 15, in particular a camera system, in order to be able to carry out an automatic quality control of the manufactured product 3. Very often there are also upstream or downstream automation systems 16 present, e.g. sprue cutter 17, centering, separating, feeding, crate and pallet stacking stations, etc., which are directly integrated into the robot controller or industrial installation 1, respectively, and controlled by it via digital or analog signals or other communication interfaces. The creation of the flow and control logic for the robot 5 or handling robot 5, respectively, and any connected automation components 16 or systems, respectively, is typically carried out in a teach-in procedure, for which an appropriate teachbox 18 or robot controller, respectively, can be used.
[0046] In order for the individual devices to be adjustable or programmable, respectively, they are preferably equipped with corresponding control electronics or controller, respectively, 19, as shown schematically, wherein the setting or programming, respectively, is entered and displayed via displays arranged on the devices or the teachbox 18. A connection can be established with the individual components via the teachbox 18, so that a correspondingly stored surface for this production resource 2 is invoked. Of course, it is also possible to program or adjust, respectively, the devices via an external component connected to the production resources 2 via an interface.
[0047] For the sake of completeness, it is also mentioned that all devices are connected to corresponding lines, in particular power supply, network and connection lines, liquid supply lines, material lines, etc., which in the interest of clarity were not displayed in the representation shown. Also, such production resources 2 are preferably combined into one or several work cells 20 to 23, as shown schematically in
[0048] For such large industrial installations 1, a very high effort is necessary for the start-up and registration of the individual production resource 2. Since the same devices or production resources, respectively, 2 are often used in the individual work cells 20 to 23, it is necessary that the greatest care be taken by the assemblers and software supervisors upon registration of the production resources 2.
[0049] According to the present invention, it is now envisioned that an automatic virtual representation is generated on the central operating unit 30, which is connected to the network 29 or to the work cell controllers 24 to 27, respectively, by activating a visualization software 31 in the central operating unit 30, which performs data exchange with the production resource 2 directly or with the individual work cells 20 to 23, in particular with the work cell controllers 24 to 27, and displays a schematic design of the industrial installation 1 preferably in the form of symbols 33 of the production resource 2 used on a screen 32 or touchscreen, respectively, i.e. that symbols 33 for the production resource 2 connected via the network 29 or the management tools 34 associated with the production resource 2, such as configuration systems 35 or database systems 36, are present and selectable on the central operating unit 30. Preferably, for each type of a production resource 2, different, preferably industry-standard symbols 33 are shown, so that on the basis of the symbols 33 it is already possible to draw conclusions about the devices or production resource, respectively, 2 contained in a work cell 20 to 23. In
[0050] After selection of one or several symbols 33 on the screen 32 of a computer or the central operating unit 30, the visualization component 101 from the associated production resource 2 or the management tool 34 is queried and retrieved or loaded, respectively, and started or executed on the computer or the central operating unit 30, i.e. a virtual representation of the operator interface of the production resource 2 and/or a virtual representation of the production resource 2 is displayed on the screen 32, which is preferably loaded directly from the production resource 2, since this ensures that, for example, in the case of newer devices with the same function which have a different design to older devices, this is also recognizable on the screen 32, so that when a device is replaced, its actual representation is always used. Subsequently, complete representation and operation of the production resources or resource, respectively, 2 is possible through the cooperation of the visualization component 101 now available on the operating unit 30 and the control software 37 running decentrally in the production resources 2.
[0051] Here, it is possible that the downloading of all visualization components 101 can be performed from the actual production resources 2 or management tool 34, respectively, by activating a software button. However, it is also possible that symbols 33 of the production resource 2 can be selected via a mouse pointer 38 or direct selection on a touch screen. For example, by positioning the mouse pointer 38 on the symbol 33 or, in the case of a touch screen, by direct selection, as schematically shown in
[0052] For the sake of completeness, it is mentioned that it is possible for an operator to switch between the symbol display, according to
[0053] A substantial simplification for the operator is achieved in the method according to the present invention by the fact that it is thereby possible that the most different instances or software versions, respectively, of a production resource 2 can be seen by the symbols 33 and, above all, can also be processed. For example, this is represented by the symbol 33 for the temperature control unit 13 in
[0054] In an advantageous embodiment, after the start-up of one or several production resources 2, the virtual production resource, in particular the visualization component 101, is transferred and stored upon initial detection, so that such large amounts of data need to be transferred only very rarely to once and subsequently in order to reduce the amount of data transferred only the corresponding process data, in particular the actual values, are transferred to the operator unit 30, i.e. that the central operating unit 30 can also read out data, for example digital or analog states, quality data, process parameters, variable values, preferably via OPC UA, from the connected production resource 2 and process or evaluate or correlate and display these across production resource or across work cells, respectively. Due to the reduction in the amount of data, this allows representation of the data in near real-time. For example, processing by means of “machine learning” or an “AI system” or a display of the signals or data, respectively, in oscilloscope representation is also possible. In this context, it is also possible for the status, error messages, etc. from the production resources 2 to be transferred directly to the central operating unit 30 and displayed, wherein preferably different colors are displayed and shown for this purpose, such as red for error messages, green for “everything in order”, blue for maintenance work, etc. In this case, a corresponding display can be shown for the symbol 33 or the virtual representation of the production resource 2, preferably in the form of a luminous dot, or alternatively the entire symbol 33 or the virtual representation of the production resource 2 can be displayed in the corresponding color.
[0055] It is also possible for the operator to have a listing of all production resources 2 generated by activating a corresponding submenu. Here, all production resources 2 can be listed one below the other and preferably in alphabetical order, whereby the associated work cell 20 to 23 is displayed next to the individual production resource 2. However, it is also possible that only a list can be evaluated in which all production resources 2 are indicated only once and next to or before this it is indicated how often this type of production resource of a production resource 2 is present in the industrial installation 1.
[0056] As a matter of principle, it should be mentioned that in the embodiment shown, the production resources 2 are combined in work cells 20 to 23, but this is not necessary; instead, the production resource 2 can be appropriately interconnected and connected to the network 29. It is also possible for the operation of the production resource 2 to take place without the work cell controls 24 to 27, but their use has the advantage that the production resource 2 can be automatically assigned to the corresponding work cells 20 to 23.
[0057] For the sake of completeness, it is mentioned that links to virtual production resources 2 or virtual work cells 20 to 23 provided locally or in the cloud are also reflected on the central operating unit or units 30, i.e., should a virtual link to a virtual production resource 2 be stored or activated, respectively, on a production resource 2, this link is also detected and displayed. This can preferably be done in different colors so that such a link is easily recognizable.
[0058] Furthermore, the central operating unit 30 can also be used for the storage of data sets, for example consisting of quality and process parameters or various settings, as well as program sequences, recipes or other configurations of individual production resources or complete work cells.
[0059] It is also possible that in addition to or instead of the central operating unit 30, the teachbox 18 of the robot 5 acts as the central operating unit 30 and thus preferably the visualization components of the production resource 2 within the work cell 20 to 23 of the robot 5 or also further work cells 20 to 23 can be selected by the user and displayed on the teach box 18. In this context, it is also possible for the terminal, in particular that of the controller 19 of the injection-molding machine 4, to act as the central operating unit 30, and thus preferably for the visualization components of the production resource 2 within the work cell 20-23 to be selected by the user and displayed on the terminal 19. Likewise, the controller of the central conveyor system 50, as shown for example in
[0060] The virtual representation of the existing production resources 2 also makes it possible for the central operating unit 30 to support the use of 3D glasses or virtual reality or mixed reality display, whereby the visualization components of the production resource are arranged and displayed to the user in three-dimensional space. It is advantageous here if the actual layout of the industrial installation 1 is recorded in the system beforehand and the production resources 2 are provided with GPS data or markers so that a virtual tour of the industrial installation 1 is possible. For a simplified acquisition of GPS data or location data, respectively, it is sufficient if the essential production resources 2, namely the injection-molding machine 4 or the work cell controller 20 to 23, are detected because their associated further production resource 2 are arranged in the vicinity. Often, their virtual representations are already supplemented to the position to the injection-molding machine 4, so that a simple assignment can be made.
[0061] It is also possible that a production resource 2, instead of being displayed and connected via a visualization component 101 running in a modular fashion on the central operating unit 30, is displayed and connected via a mirroring technology, for example VNC or TeamViewer, and/or via a web client technology, preferably a web browser element.
[0062] Furthermore, the user can change the physical units to be used in the display of the central operating unit 30 at the central operating unit 30, whereby the selected physical units are also automatically used for the visualization components 101 of the production resource 2 displayed in the central operating unit 30, or act as a default setting, respectively. It is also possible that messages are sent to the user from the central operating unit 30, triggered by events on one or several of the connected production resource 2, preferably via email, Twitter or SMS.
[0063] It is of course possible that a wide variety of settings, such as language, 2D view, 3D view, units, etc., can be set on the central operating unit 30, which can also be transferred to the production resource 2 connected via the network 29 by activating a transmission button accordingly. Here, it is possible that the touch screen or the mouse pointer 38 can be used to select one or several virtual production resource 2 to which the settings or changes are transferred. In this context, it is also possible that when changes are made to the production resource 2, for example during maintenance work, by changing the menu language, this change is displayed on the virtual production resource or the visualization component, respectively, 101.
[0064] Furthermore,
[0065] Here, preferably after the installation or assembly, respectively, of a new work cell 24 to 27, the acquisition of the production resources 2 is first carried out and the largest data volumes are downloaded, so that subsequently, after the start-up of the production resources 2, now merely a small amount of data transfer is required in order to have an almost real-time display of the parameters, setpoint/actual values, etc. available in the control room 41.
[0066] Furthermore, it is also possible that global or worldwide networking, respectively, in particular via the internet 42, of the company building 40 is possible, so that an external operating unit 43 can additionally be integrated or connected. In this case, it would be possible for the central operating unit 30 to be omitted in the company building 40 and for control, regulation and monitoring to also be carded out via the external operating unit 43. In this regard, it is also possible that the representation can be made on a tablet 44 or cell phone 45.
[0067] Optionally, the connection to an external operating unit 43 for maintenance activities or updates, respectively, of the production resources 2 is also used by the manufacturer of the production resources 2, who can provide corresponding updates via the internet 42. Here, it is also possible that the external operating unit 43 is designed as a server, and that the central operating unit 30 can use it to download updates, settings, operator manuals, etc.
[0068] Furthermore,
[0069] As briefly mentioned before, several screen displays in different display variants are shown in
[0070]
[0071] Finally,
[0072] The operator can log in to the central operating unit 30 via the “Login” button at the top right, and display and monitor the production resources 2 via its visualization components 101 hereby from the screen 32 of the central operating unit 30 according to his or her user level. For this purpose, the user level is passed on by the visualization software 31 to the visualization components 101, so that the operator has to remember only 1 password for all visualization components 101 or has to log in only 1 time, respectively, and can then operate all production resource 2 via their visualization components 101.
[0073] It is pointed out that the invention is not limited to the embodiments shown, but may comprise further embodiments and designs.
