SUMMARY OF INVENTION
Technical Problem

In a case in which the software button is in the non-selectable state, it is necessary for the worker to satisfy all of the predetermined operation conditions which are necessary for setting the software button to the selectable state. However, the worker may not be able to ascertain which operation conditions are lacking merely by viewing the touch panel. Therefore, it is necessary for the worker to investigate the operation conditions which are lacking using a manual or the like. Such work is arduous.

On this point, PTL 1 discloses an NC (Numerical Control) machine tool management system in which usability during remote operation is favorable. According to the management system described in the document, it is possible to display icons which correspond to an operational state (stopped ordinarily, operating ordinarily, stopped by a minor error, stopped by a serious error, power off) of the NC machine tool on a screen of a personal computer. However, even in the case of the management system of this document, the content which may be displayed on the screen is limited to the operational state of the NC machine tool. Therefore, an object of the present invention is to provide a work machine display device capable of improving the usability of a work machine.

Solution to Problem

(1) In order to solve the problems described above, a work machine display device of the present invention is provided with a touch panel which displays a software button and an operation condition which is necessary for selecting the software button at the same time in a state in which the software button and the operation condition are related. Here, a “software button” refers to a button which is displayed (rendered) on a touch panel and with which a worker is capable of inputting predetermined commands.

According to the work machine display device of the present invention, it is possible to display the software buttons and the operation conditions on the touch panel at the same time. In addition, it is possible to display the software buttons and the operation conditions in an interrelated state. The worker is capable of confirming the state (the selectable state or the non-selectable state) of a desired software button by merely viewing the touch panel. At the same time, in a case in which the desired software button is in the non-selectable state, the worker is capable of confirming the operation conditions which are necessary to switch to the selectable state. Therefore, it is not necessary for the worker to purposely refer to a manual or the like in order to confirm the necessary operation conditions. It is not necessary for the worker to purposely push the software button on the touch panel in order to confirm the necessary operation conditions. Therefore, according to the work machine display device of the present invention, it is possible to improve the usability of the work machine.

(2) In the configuration of (1) described above, it is preferable to adopt a configuration in which the operation condition is displayed on the touch panel in icon format. According to this configuration, the worker is capable of easily confirming the operation conditions which are necessary for selecting the desired software button regardless of country or language. It is possible to reduce the display space that the operation conditions occupy on the touch panel in comparison to a case in which the operation conditions are displayed on the touch panel in a text format (naturally, this case is also included in the configuration described above in (1)).

(3) In the configuration of (1) or (2) described above, it is preferable to adopt a configuration in which at least a portion of the operation condition is displayed to be overlaid on the software button. According to this configuration, it is possible to reduce the display space that the operation conditions occupy on the touch panel in comparison to a case in which the software buttons and the operation conditions are arranged adjacently on the touch panel (naturally, this case is also included in the configuration described above in (1)). According to this configuration, in a case in which a plurality of software buttons are displayed on the touch panel, the worker may easily associate the desired software button with the operation conditions which are necessary for the software button.

Advantageous Effects of Invention

According to the present invention, it is possible to provide a work machine display device capable of improving the usability of a work machine.

DESCRIPTION OF EMBODIMENTS

Hereinafter, description will be given of the embodiments of the work machine display device of the present invention.

First, description will be given of the configuration of the NC machine tool which is provided with the work machine display device of the present embodiment. FIG. 1 illustrates a block diagram of the NC machine tool. As illustrated in FIG. 1, an NC machine tool 1 is provided with a work machine 2, a control device 3, and a work machine display device 4.

The work machine 2 subjects a work (not illustrated) to predetermined processing. The control device 3 controls the work machine 2. The work machine display device 4 is electrically connected to the control device 3. The work machine display device 4 is disposed on the outer surface of a housing of the work machine 2. The work machine display device 4 is a so-called operation panel. The work machine display device 4 is provided with a touch panel 5 and a selection switch 6. A worker is capable of confirming information of the work machine 2 via the touch panel 5 and the control device 3. The worker is capable of operating the work machine 2 via the touch panel 5 and the control device 3. By turning the selection switch 6 to the left and the right, the worker is capable of switching a program for the work machine 2 between an editable state and a non-editable state. In order to turn the selection switch 6, it is necessary to insert a predetermined key (not illustrated) into a keyhole (not illustrated) of the selection switch in advance.

Next, description will be given of the touch panel. FIG. 2 illustrates a (first) schematic diagram of the touch panel of the work machine display device of the present embodiment. FIG. 2 illustrates a case in which software buttons (a program selection button 500, a program addition button 501, a program copy button 502, and a program deletion button 503) are in a selectable state.

Here, the selectable state refers to a state in which, by pushing (touching) each software button, the worker is capable of inputting a command corresponding to the software button to the NC machine tool 1. Conversely, the non-selectable state refers to a state in which, even if each software button is pushed (even if each software button is touched), the worker is not capable of inputting a command corresponding to the software button to the NC machine tool 1.

As illustrated in FIG. 2, the control device 3 is capable of displaying an icon section 50 and a list section 51 on the touch panel 5. A plurality of icons are arranged into two levels, an upper level and a lower level, in the icon section 50. Of these, the program selection button 500, the program addition button 501, the program copy button 502, and the program deletion button 503 are arranged in the lower level.

The worker is capable of selecting a desired program from among a list display field 510 which is described later by pushing (touching) the program selection button 500. For example, the worker is capable of selecting a “program 00003”.

The worker is capable of newly adding a program number by pushing (touching) the program addition button 501. Specifically, when the worker pushes the program addition button 501, the control device 3 displays a number pad (not illustrated) on the touch panel 5. Using the number pad, the worker is capable of newly adding a program number. For example, when the worker uses the number pad to newly add a program number “00009”, the control device 3 creates and saves an empty (yet to be input) “program 00009”.

The worker is capable of copying a selected program by pushing (touching) the program copy button 502. Specifically, when the worker pushes the program copy button 502, the control device 3 displays a number pad on the touch panel 5. Using the number pad, the worker is capable of inputting program numbers of a copy source and a copy destination. For example, when the worker uses the number pad to input the program number “00003” of a copy source and to input the program number “00009” of a copy destination, the control device 3 creates and saves the “program 00009” with the same content as the “program 00003”.

The worker is capable of deleting a selected program by pushing (touching) the program deletion button 503. Specifically, when the worker pushes the program deletion button 503, the control device 3 displays a number pad on the touch panel 5. Using the number pad, the worker is capable of inputting a program number which the worker wishes to delete. For example, when the worker uses the number pad to input the program number “00003” which the worker wishes to delete, the control device 3 displays a confirmation message (for example, “really delete?”, “the deleted program may not be restored”, or the like), and intention declaration buttons in relation to the confirmation message (for example, an approval button (“yes”, “execute”, or the like), a deny button (“no”, “cancel”, or the like)) on the touch panel 5. Among the intention declaration buttons, when the worker pushes (touches) the confirmation button, the control device 3 deletes the “program 00003”.

The list section 51 is arranged below the icon section 50. The list section 51 is provided with the list display field 510 and a program display field 511. A list of programs for work processing is displayed in the list display field 510. The content of the “program 00003” which is selected in the list display field 510 is displayed in the program display field 511.

To facilitate the description, in FIG. 2, the selected “program 00003” is surrounded with a dotted line box. In actuality, in the selected “program 00003”, in comparison to a “program 00002” which is not selected, or the like, white is converted to black. Additionally, black is converted to gray. Therefore, the worker may easily confirm the selected program.

FIG. 3 illustrates a (second) schematic diagram of the touch panel of the work machine display device of the present embodiment. FIG. 4 illustrates an enlarged view of the inside of box IV of FIG. 3. FIG. 5 illustrates an enlarged view of the inside of box V of FIG. 3. FIGS. 3 to 5 illustrate a case in which the software buttons (the program selection button 500, the program addition button 501, the program copy button 502, and the program deletion button 503) are in a non-selectable state.

To facilitate the description, in FIGS. 3 to 5, the software buttons (the program selection button 500, the program addition button 501, the program copy button 502, and the program deletion button 503) which are in a non-selectable state are illustrated using dotted lines. In actuality, in regard to the software buttons, when comparing the selectable state illustrated in FIG. 2 to the non-selectable state illustrated in FIGS. 3 to 5, the selectable state (FIG. 2) has a greater shade contrast in gray-scale display than the non-selectable state (FIGS. 3 to 5).

Operation condition icons are overlaid on the upper right corner portions of the software buttons. The overlaid operation condition icons indicate operation conditions of the software buttons. For example, as illustrated in FIG. 4, a stop operation icon 505 is overlaid on the upper right corner portion of the program selection button 500. The stop operation icon 505 indicates an operation condition “stop operation of the work machine 2”. By confirming the stop operation icon 505, the worker may recognize that the program selection button 500 will enter the selectable state (FIG. 2) if the operation of the work machine 2 is stopped.

As illustrated in FIG. 4, an edit key icon 506 and an NC mode icon 507 are overlaid on the upper right corner portion of the program addition button 501. The edit key icon 506 indicates an operation condition “switch the selection switch 6 to the editable state using a key”. The NC mode icon 507 indicates an operation condition “switch the mode of the NC machine tool 1 from automatic mode (refer to a mode switch icon 509 of FIG. 3) to edit mode”. By confirming the edit key icon 506 and the NC mode icon 507, the worker may recognize that the program addition button 501 will enter the selectable state (FIG. 2) if the selection switch 6 is switched to the editable state using a key, and the mode of the NC machine tool 1 is switched to the edit mode.

As illustrated in FIG. 5, the edit key icon 506 and the NC mode icon 507 are also overlaid on the upper right corner portion of the program copy button 502 in the same manner as the program addition button 501.

As illustrated in FIG. 5, a password input icon 508 and the NC mode icon 507 are overlaid on the upper right corner portion of the program deletion button 503. The password input icon 508 indicates an operation condition “input password”. By confirming the password input icon 508 and the NC mode icon 507, the worker may recognize that the program deletion button 503 will enter the selectable state (FIG. 2) if the number pad is displayed on the touch panel 5, a password is input via the number pad, and the mode of the NC machine tool 1 is switched to the edit mode.

Next, description will be given of the operation method of the touch panel. FIG. 6 illustrates a flowchart of the operation method of the touch panel. First, the worker confirms whether the desired software button (the program selection button 500, the program addition button 501, the program copy button 502, or the program deletion button 503) is in the selectable state (FIG. 2) or, alternatively, in the non-selectable state (FIGS. 3 to 5) (S1 (step 1, same hereinafter) of FIG. 6).

In step 1, in a case in which the desired software button is in the selectable state (FIG. 2), the worker touches the software button (S2 of FIG. 6). The control device 3 illustrated in FIG. 1 executes the command corresponding to the software button which is touched by the worker (S3 of FIG. 6).

In step 1, in a case in which the desired software button is in the non-selectable state (FIGS. 3 to 5), the worker confirms the operation conditions (S4 of FIG. 6). Specifically, the worker confirms the operation condition icon (the stop operation icon 505, the edit key icon 506, the NC mode icon 507, or the password input icon 508) which overlaps the upper right corner portion of the software button. Next, the worker readies the operation conditions based on the operation condition icons corresponding to the desired software button (S5 of FIG. 6). When the operation conditions are ready, the control device 3 illustrated in FIG. 1 removes the operation condition icons from the upper right corner portion of the software button. The control device 3 switches the software button from the non-selectable state (FIGS. 3 to 5) to the selectable state (FIG. 2). The worker touches the software button (S2 of FIG. 6). The control device 3 executes the command corresponding to the software button which is touched by the worker (S3 of FIG. 6).

Next, description will be given of the operations and effects of the work machine display device of the present embodiment. According to the work machine display device 4 of the present embodiment, as illustrated in FIGS. 3 to 5, in the non-selectable state, it is possible to display the software buttons (the program selection button 500, the program addition button 501, the program copy button 502, and the program deletion button 503), and the operation condition icons (the stop operation icon 505, the edit key icon 506, the NC mode icon 507, and the password input icon 508) at the same time on the touch panel 5. In addition, it is possible to display the software buttons and the operation condition icons in an interrelated state.

The worker is capable of confirming the state (the selectable state (FIG. 2) or the non-selectable state (FIGS. 3 to 5)) of a desired software button by merely viewing the touch panel 5. At the same time, in a case in which the desired software button is in the non-selectable state (FIGS. 3 to 5), the worker is capable of confirming the operation conditions which are necessary to switch to the selectable state (FIG. 2) by viewing the operation condition icons. Therefore, it is not necessary for the worker to purposely refer to a manual or the like in order to confirm the necessary operation conditions. It is not necessary for the worker to purposely push the software button on the touch panel 5 in order to confirm the necessary operation conditions. Therefore, according to the work machine display device 4 of the present embodiment, it is possible to improve the usability of the work machine 2.

As illustrated in FIGS. 3 to 5, the operation conditions of the software buttons are displayed on the touch panel 5 as the operation condition icons. Therefore, the worker is capable of easily confirming the operation conditions which are necessary for selecting the desired software button regardless of country or language. It is possible to reduce the display space that the operation conditions occupy in the touch panel 5 in comparison to a case in which the operation conditions are displayed on the touch panel 5 in a text format.

As illustrated in FIGS. 3 to 5, the entirety of the operation condition icons overwrite the upper right corner portion of the software buttons. Therefore, in comparison to a case in which the software buttons and the operation condition icons are arranged adjacently on the touch panel 5, it is possible to reduce the display space that the operation condition icons occupy on the touch panel 5. The worker may easily associate the desired software button with the operation condition icons which are necessary for the software button even though a plurality of software buttons are displayed on the touch panel 5.

<Other>

Hereunto, description is given of an embodiment of the work machine display device of the present invention. However, the embodiment is not particularly limited to the above. It is possible to embody in various modified modes and improved modes which a person skilled in the art is capable of carrying out.

FIG. 7 illustrates an enlarged view of a portion of the touch panel of the work machine display device of a (first) other embodiment. The same signs will be used for parts corresponding to those of FIG. 4. As illustrated in FIG. 7, the software buttons (the program selection button 500 and the program addition button 501), and the operation condition icons (the stop operation icon 505, the edit key icon 506, and the NC mode icon 507) for setting the software buttons to the selectable state may be arranged to be adjacent in the vertical direction. A portion of the software button and the operation condition icon may be allowed to overlap. The software button and the operation condition icon may be allowed to be in contact. In other words, in a case in which a plurality of software buttons and a plurality of operation condition icons are arranged on the touch panel, the worker may visually relate the desired software button to the operation condition icons for setting the software button to the selectable state.

FIG. 8 illustrates an enlarged view of a portion of the touch panel of the work machine display device of a (second) other embodiment. The same signs will be used for parts corresponding to those of FIG. 4. As illustrated in FIG. 8, the operation conditions may be displayed using text. In this case, in comparison to a case in which the operation conditions are displayed on the touch panel as the operation condition icons, it is not necessary for the worker to remember the meaning of the operation condition icons.

FIG. 9 illustrates an enlarged view of a portion of the touch panel of the work machine display device of a (third) other embodiment. The same signs will be used for parts corresponding to those of FIG. 4. As illustrated in FIG. 9, two operation condition icons (the edit key icon 506 and the NC mode icon 507) may be overlaid on a software button (the program addition button 501). In this case, the operation condition icons may be overlaid from top to bottom according to the operation order. For example, in a case in which it is necessary to perform an operation relating to the edit key icon 506 before performing an operation relating to the NC mode icon 507, the edit key icon 506 of the top side may be stacked and displayed on the NC mode icon 507 of the bottom side. Here, in a case in which a plurality of operation condition icons are displayed on a single software button, the worker may easily confirm the order of operations relating to the plurality of operation condition icons. Naturally, the vertical arrangement of the plurality of operation condition icons may be set without relation to the operation order.

Each of the control device 3 and the work machine display device 4 illustrated in FIG. 1 may be a PC (Personal Computer) which is externally attached to the NC machine tool 1, a tablet PC, a laptop, a smart phone, a mobile phone, a PDA (Personal Digital Assistant), or the like.

The display method of the selectable state illustrated in FIG. 2 and the non-selectable state illustrated in FIGS. 3 to 5 is not particularly limited. The selectable state and the non-selectable state may be depicted distinctly using a difference in the color (hue, brightness, saturation, or any combination thereof) of the software buttons, a difference in the size of line rendering of the software, a difference in the type of line rendering (solid lines, dotted lines, dot-and-dash lines, and the like) of the software buttons, a difference in the width of line rendering (thick lines, thin lines, and the like) of the software buttons, or the like. In other words, the worker may view the software button and distinguish the selectable state from the non-selectable state.

When the operation conditions relating to the desired software button are ready, the control device 3 may change the state of the operation condition icons corresponding to the operation conditions. For example, when the operation conditions relating to the desired software button are ready, the control device 3 may remove the operation condition icons. Specifically, the control device 3 may gradually remove the operation condition icons. The control device 3 may remove the operation condition icons after causing the operation condition icons to blink. The control device 3 may remove the operation condition icons while reducing the size of the display surface area of the operation condition icons.

When the operation conditions relating to the desired software button are ready, the control device 3 may reduce the size of the display surface area of the operation condition icons corresponding to the operation conditions. The control device 3 may move the operation condition icons from a predetermined position to another position. The control device 3 may change the color, line type, and contrast of the operation condition icons. In this case, the worker is capable of easily and visually confirming that the operation conditions are ready.

The type of the work machine 2 illustrated in FIG. 1 is not particularly limited. The work machine 2 may be a machine tool (a machining center, a lathe, a miller, a drill press, or a milling cell) which processes a work, a screen printer which prints solder onto a board, an electronic component mounting machine which mounts electronic components onto a printed circuit board, or the like. The electrical connection between the work machine 2 and the control device 3 illustrated in FIG. 1, and the electrical connection between the control device 3 and the work machine display device 4 may each be either wired or wireless.
