A sub-form screen for specifying and displaying the classification management data from the management data group on the data command button screen. The sub-screen consists of a monitor screen, and the division management data for each of multiple machines specified on the screen of the display unit of the personal computer is specified on the subform screen and specified without frequently switching the screen of the display unit. It is possible to display the management data of multiple machines simultaneously on the same screen.

According to the invention of claim 1, data input to each NC device of a plurality of NC machine tools installed at a distance and output values of management data during machining are sequentially output for each machine. Frequent screen operations when confirming by switching are operations that are unnecessary for the original data management. In order to eliminate these switching operations, a plurality of NC units and one personal computer are connected by a high-speed communication line, and the display unit designates a plurality of processing machines and manages the classification of a plurality of machines. It is possible to display the specified data at the same time by operating on the same screen, and then change and display the displayed division management data to another division management data of another machine. Therefore, not only the data of the number of processing machines that can be displayed simultaneously on the subform screen but also the management data of the dozens of processing machines set in the original personal computer can be grasped.

[0010] Further, in the invention described in claim 2, the main form screen after machine designation is replaced with the machine designation command button screen, and the same number of machine number change command button screens as the designated machine is displayed in the lower part. The same number of subform screens as the designated machine are displayed and configured.The subform screen is composed of a title bar screen including the machine number and model number of the designated machine at the upper part of the subform screen and the classification management data at the center part. It consists of a screen to be displayed and a data comment screen to specify the category in the lower part.

The classification management data for the specified multiple machines can be specified on the data command button screen on the subform screen displayed on the same screen. In this way, the required sorting management data to be displayed on the subform screen can be switched by a simple operation using the keyboard or mouse, and the management data of each machine can be switched for all the managed machines. Can be displayed on the monitor and managed.

[0012] In the invention according to claim 3, the display of the division management data on the subform screen is performed by displaying the division management data on the subform screen at intervals of a display update time set in advance in a timer of a personal computer. The display is switched sequentially.

According to the invention of claim 3, the display of the division management data for each division is automatically switched on the subform screen by the timer of the parsol computer at every display update time set in advance as necessary, and sequentially displayed. It is like that. It is possible to switch to the specified category management data and display it at any time by a forced interrupt display command from the operator.

In the invention according to claim 4, the classification management data includes an NC monitor screen for displaying tool position data, a machining state, a tool state, an NC mode, and the like, and an operation time, the number of machining, an alarm history, and the like. An operation status screen to be displayed, an upload screen for uploading the CNC program of the numerical controller to a program file of a personal computer, a download screen for downloading the data of the program file to the numerical controller, And a screen for transferring program file data for operation to the CNC operation buffer of the machine.

According to the invention of claim 4, by dividing the management data of the machine according to the management purpose, the display significance of the data displayed on the subform screen is clarified and the operation is simplified. I have. The setting for the management purpose is optional, and the content to be included in each item can be set as appropriate. It should be categorized according to where the focus of management is. By dividing the data into division management data, the amount of display data included in one division is reduced, and the same kind of division management data with different machine numbers can be displayed on the same screen in comparison.

The invention according to claim 5 is characterized in that when an alarm occurs in a machine registered in the personal computer as an object of group management during display of the subform screen, an alarm history is displayed. The division management data screen of the machine, in which the alarm data is displayed on the operation status screen, is preferentially displayed in a predetermined subform screen.

According to the invention of claim 5, in addition to the normal screen switching in which the operator switches and manages the sub-form screen division management data that is switched and displayed at regular time intervals as necessary, the sub-form screen is switched during operation. When an alarm occurs on a machine that is not specified on the main form screen among multiple units, it is displayed on the operation status screen that displays the alarm history, and this screen is prioritized as sort management data. And display it immediately. This is to facilitate the operator's response to the complaint processing by displaying the machine number and the alarm data in an interrupted manner. The alarm history is normally displayed in the operation status screen of the subform screen, but the operation status screen compensates for this because the display update time interval is long.

[Embodiment] In the present invention, a plurality of NC machine tools and a personal computer are connected by a high-speed communication line, and management data for each machine is displayed on a display unit of the personal computer to perform group management of the machine tools to be managed. Things. In particular, by switching the display of the management data of multiple machines sequentially at a predetermined cycle time, or by specifying the machine number and specifying the management data to be displayed on the screen, the management data of the specified machines can be arranged in parallel. And display it. Therefore, the personal computer and the NC device to be managed are connected by a high-speed communication line, and the personal computer main body 3 is provided with some processing means for group management.

The signal flow relating to the management data supplied to the “machine monitor screen” according to the present invention is as follows. In FIG. 1, an NC device 1 of a machine tool to be managed is connected to a personal computer main body 3 via a high-speed communication line 2. The personal computer main body 3 has machine switching means 4 so that data from each machine tool is sequentially inputted, and stores the machine switching means 4 in the input data storage means 5. All of the stored management data are input to the subform data storage means 7 in accordance with the management purpose. The display interval of the subform screen is set in the timer 8, and each of the division management data is displayed on the subform screen at each set time. The stored section management data can be called out to the display unit 12 each time by the keyboard 10 or the mouse 11 of the command means, and is output to the display unit 12 according to the program inputted to the display control means 9.

The designation of the machine number on the screen of the display unit 12 is performed by the main form screen 15A. The NC monitor screen 25, the movable state screen 26, the upload screen 27, the download screen 28, and the DNC operation screen 29 of the division management data are displayed. The machine monitor screen is configured so that one screen can be specified by a simple operation on the subform screen 20 and that the machine number and the division management data can be changed. The operator who manages the group inputs designation of the machine to be managed to the personal computer by label or icon processing on the main form screen 15A of the display unit screen.

In FIG. 2A, a property screen 16 for designating the number of machines and a machine command button screen 17 are provided at the lower right of the main form screen 15A before designating the management target machines. Have been. The machine designation command button screen 17 is numbered in correspondence with the machine number to be managed. The display is designated on the property screen 16 of the main form screen 15A. Enter the number of machines (four in this embodiment) and enter the machine number to be managed on the machine designation command button screen.

In FIG. 3, the main form screen 15B after machine designation shows a title bar screen 18 which is data for displaying the designated machine at a position where the subform screen 20 is to be displayed. The machine number and model symbol are displayed on the machine number change command button screen 19 provided in the lower part. By operating the command button screen 19 for changing the machine number, a subform screen 20 is displayed at the position of the title bar screen 18. The same number of subform screens 20 as the designated number are arranged and arranged. The subform screen 20 is provided with a title bar screen 18 at the upper left and a data command button screen 21 of a number corresponding to the number of divisions of the division management data at the lower part. In the center of the subform screen 20, the division management data specified on the data command button screen 21 is displayed.

The sorting management data displayed on the subform screen 20 is management data of high necessity to be displayed by sorting management data of each machine according to a management purpose, management data to be displayed with a shorter time interval, and work data to be displayed. The management data required for the management of multiple machines, such as management data required to check the progress of the operation, management data required to send work data directly to the machine via the personal computer, etc., is displayed separately according to its purpose. Things.

In the embodiment, an NC monitor screen 25 (FIG. 4A) for displaying and managing tool position data, machining state, tool state, NC mode and the like in a working state, operation time, number of machining, alarm history An operation status screen 26 (FIG. 4B) for managing the production status including data and the like, in order to transfer the NC data of a specific machine tool to the personal computer main body 3 so that the same machining can be performed on another machine tool. NC program upload screen 27 [FIG. 4 (c)], NC program download screen 28 for transferring the NC data uploaded to the personal computer 3 to another NC device [FIG. 4 (d)], NC program A large number of programs that cannot be stored in the device are stored in the main body of the personal computer, and the DNC operation screen 29 for directly numerically controlling the machine tool [FIG. )].

The change in the display of the division management data displayed on the subform screen 20 is changed only by operating the data command button screen 21 in the subform screen 20 within the same device number. When displaying the management data of the machine not specified on the main form screen 15A, the main form screen 15A is called on the property screen 16 of the main form screen 15A, and the specification is changed on the machine specification command button screen 17. By this operation, one subform screen 20 is rewritten to the subform screen 20 to which the title bar screen 18 of the changed machine number is added, and becomes a screen displaying any of the division management data. Then, if the user commands the division management data to be displayed by operating the data command button 21, predetermined division management data is displayed. The display of the division management data displayed on the subform screen 20 is automatically switched at regular intervals set by a timer.

In the personal computer body 3, the management data is sequentially input to the input data storage unit 5 through a time-division communication network connected to the NC device 1 to be managed by a high-speed communication line. These input data are processed by the data calculation means 6 into the division management data, and are stored for each machine number in the subform data storage means 7 which stores the data in subform units. In addition, the display of the divided management data of each subform screen is switched at regular time intervals. The time interval for switching the display is set by the display interval setting timer 8 of the personal computer 3. In the section management data, the display switching time can be set for each section. For example, the NC monitor screen 25 where the position data changes every 2 seconds, the operation status screen 26 does not need to be displayed urgently based on its contents, so every 50 seconds, the DNC operation screen 29 is directly displayed by the personal computer body 13. It is set so that the display is switched every 0.18 seconds for control.

The operation status screen 26 displays data such as operation time, data on the number of unprocessed and already processed workpieces, and the summation of history data on the contents of machine alarm occurrences. Switching of the display does not cause a problem even if the display is made at relatively long intervals. However, if an alarm actually occurs, it is displayed immediately and the contents of the alarm are displayed so that it is clear whether the alarm is of operation, tool, work, or NC so that prompt response can be taken. For this reason, in principle, the alarm status is displayed for all the machine tools that are being managed, and the operation status screen that displays the machine number where the alarm occurred on the specific subform screen 20 when the alarm occurs as the title bar 26 is interrupted and displayed, and the display color is preferentially changed for a certain time and displayed as the latest information on the alarm history screen.

The contents of management data required for machine management are various. NC programs such as machining conditions, tool conditions, and workpiece shape conditions must be properly input before the machine is machined. In addition, after the start of processing, it is possible to track whether the processing is progressing properly and whether it is responding appropriately to the generated alarm by using the alarm history data. In addition, it can be displayed and confirmed that the planned production amount is secured. If the processing machine is equipped with an automatic measuring device, it can display the measurement data and control the quality of products and monitor the state of the tools mounted on the machine. In this way, a wide range of management data is appropriately divided according to the purpose of management, and even if the number of management divisions is increased to four or more, the division management data that can be displayed in the subform is multi-partitioned. By displaying the classification management data of different machines or the same machine on the same screen, efficient group management becomes possible.

The operation of the “structure of the machine monitor screen” that returns to the present invention will be described with reference to the flowchart of FIG.

In step S 1, a management data display system composed of the main form screens 15 A and 15 B and the subform screen 20 is specified on the display unit 12 of the personal computer. In step S2, it is determined whether the selection of the management data display system has been completed. This determination is made based on whether the input screen of the machine number to be managed is displayed on the screen in step S3. In step S4, the same number of machine command button screens 17 as the group management target machines are displayed, and a machine command button screen is operated from the screens to designate machines for which management data is to be displayed. Even if the machine was not initially specified, the classification management data can be displayed by changing the machine number later (see step S18).

In step S5, a title bar screen 18 and a machine number change command button screen 19 of the machine specified in step S4 are displayed in the main form screen instead of the machine command button screen 17. In step S6, a subform screen 20 having a title bar screen 18 for each machine designated in the screen is displayed in place of the machine button change command button screen 19.

In step S 7, it is determined whether the basic screen of the subform screen 20 has been displayed for the designated machine. At this time, any of the division management data 25 to 29 is displayed on the subform screen 20. If the designated display has not been executed, the process returns to step S3. In step S8, it is determined whether or not the machine number displayed on the subform screen 20 has been changed. If there is a change, in step S9, the property screen 16 on the main form screen 15B is operated to return to step S4 to change the designation of the machine number. If there is no change, in step S10, a command is issued on the data command button screen 21 to call the division management data to be displayed in the subform screen 20.

In step S 11, a display interval update timer 8 for the section management data to be displayed is set in advance for each section management data. In step S12, a command is issued to automatically switch and display the content of the data to be displayed on the subform screen 20 at every timer set time. In step S13, an alarm signal is generated during the display by the automatic switching of the division management data, and the operator determines the necessity of displaying the division management data necessary for the management when the operator knows the contents of the alarm and takes action. In step S14, if the display screen needs to be forcibly changed, an interrupt display is commanded.

If there is no need to forcibly change the screen, in step S 15, the data on the subform screen 20 is read in accordance with the program of the entered machine number and sorting management data or in accordance with the display time interval set by the timer 8. Is automatically switched and displayed. If it becomes necessary to forcibly change the display, an instruction is given in step S14 to interrupt and display the image. In step S16, the personal computer main body 3 performs an alarm signal process, and then in step S17, the display of the subform screen 20 is switched to the operation status screen to display the details of the alarm.

In the same interrupt display, the operator may spontaneously switch data on the subform screen 20. In steps S18 and S19, the stationary signal transmission is interrupted, and the operation of the machine number change command button screen 19 on the main form screen 20 and the data command button screen 21 on the subform screen 20 are operated to sort the management data screen 25. Change display of ~ 29.
