This application claims the priority of European Patent Application, Serial No. 07025143, filed Dec. 27, 2007, pursuant to 35 U.S.C. 119(a)-(d), the content of which is incorporated herein by reference in its entirety as if fully set forth herein.
The invention relates to an operator control unit for operating a machine tool, a production machine, a crane and/or a robot. More particularly, the invention relates to a method for assigning an on-screen display to a softkey button in an operator control unit for operating a machine tool, a production machine, a crane and/or a robot.
Nothing in the following discussion of the state of the art is to be construed as an admission of prior art.
Machine tools, production machines, cranes and/or robots are customarily operated using operator control units that have suitable operating buttons. What are known as softkey buttons are increasingly being used in this case. A softkey button denotes a button that performs different functions depending on an on-screen display shown on a screen of the operator control unit.
Softkey buttons in an operator control unit for operating a machine tool, a production machine, a crane and/or a robot are customarily assigned by means of complex changes to configuration files or via complex, a long-winded sequence of additional operating dialog screens.
In commercially available operator control units, if an operator wishes to execute a particular control action, at present he must often perform a protracted procedure of frequently pressing the softkey buttons repeatedly to select menus and associated submenus before he can execute an operating function associated with a particular on-screen display.
It would be desirable and advantageous to provide an improved to obviate prior art shortcomings and to provide straightforward assignment of an on-screen display to a softkey button in an operator control unit for operating a machine tool, a production machine, a crane and/or a robot.
According to one aspect of the present invention, an operator control unit for operating a machine tool, a production machine, a crane and/or a robot includes a screen to display an on-screen display when the on-screen display is invoked, an operating button to display a user menu as an on-screen display when the operating button is pressed, and softkey buttons which assign an invoked on-screen display to a softkey button when the softkey button is pressed for a given length of time
According to another aspect of the present invention, a machine tool, production machine, crane and/or robot includes a screen displaying an on-screen display when the on-screen display is invoked, an operating button displaying a user menu as an on-screen display when the operating button is pressed, and softkey buttons assigning an invoked on-screen display to a softkey button when the softkey button is pressed for a given length of time.
According to still another aspect of the present invention, a method for assigning an on-screen display to a softkey button in an operator control unit for operating a machine tool, a production machine, a crane and/or a robot, includes the steps of invoking an on-screen display, pressing an operating button so as to display a user menu, pressing a softkey button for a predetermined length of time so that the softkey button is assigned to the invoked on-screen display.
Other features and advantages of the present invention will be more readily apparent upon reading the following description of currently preferred exemplified embodiments of the invention with reference to the accompanying drawing, in which:
Throughout all the figures, same or corresponding elements may generally be indicated by same reference numerals. These depicted embodiments are to be understood as illustrative of the invention and not as limiting in any way. It should also be understood that the figures are not necessarily to scale and that the embodiments are sometimes illustrated by graphic symbols, phantom lines, diagrammatic representations and fragmentary views. In certain instances, details which are not necessary for an understanding of the present invention or which render other details difficult to perceive may have been omitted.
A function (“New”, “Open”, “Save”, “Copy”) associated with the on-screen display currently being displayed in each case is displayed in the button labeling fields 5a, 5b, 5c and 5d. In this case the softkey button 3a is assigned to the button labeling field 5a, the softkey button 3b to the button labeling field 5b, the softkey button 3c to the button labeling field 5c and the softkey button 3d to the button labeling field 5d. In the exemplary embodiment, a part program 8, e.g. in the form of a file (file symbol), is currently displayed in the on-screen function panel 7. The respective function is shown in the button labeling fields and is executed on pressing the respectively assigned softkey button. Hence different functions can be assigned to the softkey buttons depending on the on-screen display currently being displayed and will be shown in the button labeling field assigned to the respective softkey button.
By pressing the softkey button 3b, for example, which corresponds to the “Open” function shown in the button labeling field 5b, the file is opened and an on-screen display 6′ is simultaneously invoked. As shown in
The softkey buttons are hence not assigned fixed functions, but these functions can change depending on the on-screen display currently invoked and displayed.
To perform a certain function in the case of commercially available operator control units, the user must often press the softkey buttons to key through various menus, especially their submenus, that exist in the form of different on-screen displays, before he reaches an on-screen display in which he can execute the desired function.
This is where the invention comes into effect. By affording the operator an opportunity for straightforward assignment of a particular on-screen display to a softkey button, the invention provides the operator a quick facility for performing the relevant operating function without needing to use the softkey buttons to key through each of the menus displayed by the on-screen displays before he can execute the desired function.
According to the invention, the operator control unit 1 comprises for this purpose an operating button 4, which is permanently assigned a user menu. In the user menu the on-screen display 6′ shown in
After pressing the operating button 4, the previously invoked on-screen function panel 7′ of the on-screen display 6′ is preferably displayed in the user menu 10 as the on-screen function panel 7″.
The previously invoked on-screen display 6′, as already mentioned, is now assigned the softkey button 3a in the user menu 10. From now on, the on-screen display 6′ can be invoked by the operator easily and directly from any displayed on-screen display, and hence from any menu, by the operator pressing the operating button 4 and the user menu 10 being displayed to him after pressing the operating button 4, and, in the user menu, by his then pressing briefly the softkey button 3a already assigned earlier in the user menu to the on-screen display 6′. After pressing the softkey button 3a in the user menu, the on-screen display 6′ as shown in
Of course where a touch-sensitive screen (touch screen) is used, the softkey buttons can also be displayed in the form of virtual buttons on the screen, and preferably in the position of the button labeling fields so that button labeling fields and softkey buttons form a visual unit.
While the invention has been illustrated and described in connection with currently preferred embodiments shown and described in detail, it is not intended to be limited to the details shown since various modifications and structural changes may be made without departing in any way from the spirit of the present invention. The embodiments were chosen and described in order to best explain the principles of the invention and practical application to thereby enable a person skilled in the art to best utilize the invention and various embodiments with various modifications as are suited to the particular use contemplated.
