〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a diagram schematically showing the configuration of a display system of a numerical control device of the present invention. In the figure, the CRTl is composed of a timing signal generating section 2, an automatic switching circuit 3, and a display section 4. A plurality of (for example, four) numerical control devices (CNC) 51 to 54 are connected to this CRTl.

The timing signal generator 2 includes a graphic control circuit (C
(RTC) and automatically generates timing signals. This timing signal is transmitted to the timing signal sending section 6
It is sent to CNCs 51 to 54 via.

In response to this timing signal, the CNCs 51 to 54
Each screen information from the CPU (microprocessor, not shown) in the NCs 51 to 54 is converted into a video signal and sequentially sent to the CRTI. This screen information consists of position information of tools, workpieces, etc., alarm messages, etc., and has an amount of information equivalent to one screen of the CRTI.

The screen information (video signal) of CNC51-54 is CRT
The video signal is sent to the automatic switching circuit 3 via the video signal input section (interface) 7 in the I.

The automatic switching circuit 3 switches the CNCs 51 to 5 in synchronization with the timing signal directly sent from the timing signal generator 2.
4 screen information is automatically switched sequentially. That is, the automatic switching circuit 3 cuts out a part from the screen information for one screen of the CNCs 51 to 54 to generate partial screen information, and sends it to the display unit 4. The details will be described later.

Note that an operating section 8 is connected to the automatic switching circuit 3, and the automatic switching circuit 3 is operated in response to a signal from the operating section 8. The details will be described later.

FIG. 2 is a time chart showing the relationship between timing signals and CNC screen information in the automatic switching circuit. In the figure, timing signals T1, T2, T3 and T4 are signals sent directly from the timing signal generator 2 (FIG. 1) to the automatic switching circuit 3 (FIG. 1). These timing signals T1 to T4 are simultaneously applied to the CNC51.
, 52, 53 and 54 (FIG. 1).

Screen information A, B, C, and D are screen information of CNCs 51 to 54, and partial screen information A1 to A4, B1 to CNC, respectively.
It is composed of B4, C1 to C4, and D1 to D4.

First, screen information (video signal) A of the CNC 51 is sent from the CNC 51. The screen information A is sent with a delay of time ΔT with respect to the timing signal T1 directly sent from the timing signal generator 2.

This screen information A is switched to the next screen information in synchronization with the timing signal T2 directly sent from the timing signal generator 2. Therefore, only the partial screen information A1 at the beginning of the screen information A is extracted. This partial screen information A1 is sent to the display section 4 (FIG. 1).

Next, screen information B of the CNC 52 is sent from the CNC 52. This screen information B, like the screen information A, is sent with a delay of T relative to the timing signal T2 directly sent from the timing signal generator 2. In addition, in synchronization with the timing signal T3 directly sent from the timing signal generator 2, partial screen information B1 of the leading part is generated.
Only the image is cut out and sent to the display section 4.

Thereafter, in the same manner, partial screen information C1 of screen information C and partial screen information D1 of screen information D are cut out, and each of them is cut out from the display section 4.
sent to.

FIG. 3 shows the CR by the display method of the numerical control device of the present invention.
It is a figure showing an example of one screen of T. In the figure, display section 4
Partial screen information A1, B1, C1, and DI of the CNCs 51, 52, 53, and 54 are displayed in order from the top on the screen 4a. The partial screen information A1 to D1 is, for example, eight lines from the first line of each of the screen information A to D, and each of these eight lines of partial screen information constitutes 32 lines of one screen.

For this reason, when creating screen information A-D, important information (e.g. position information, alarm message) should be entered at the beginning, and detailed information (e.g. machining program tool correction amount) should be entered manually in the other parts. If this is done, only important information for all CNCs will be displayed simultaneously on this screen 4a. In other words, important information of all CNCs can be observed and referenced simultaneously on -3 CRTs.

FIG. 4 shows the CR by the display method of the numerical control device of the present invention.
It is a figure showing the operation part of T. In the figure, the operation section 8 of the CRTI consists of five soft keys.

The left soft key 8a is a shared switch and is connected to the automatic switching circuit 3. When this soft key 8a is pressed, the automatic switching circuit 3 is activated and the third screen is displayed on the screen 4a.
The screen shown in the figure will be displayed.

That is, important information for each CNC is displayed simultaneously.

The other soft keys 8b-8e are manual changeover switches and are connected to a conventional manual changeover circuit (not shown). When one of the soft keys 8b to 8e is pressed, the manual switching circuit is activated and all of the CNC screen information corresponding to that soft key is displayed on the screen 4a. For example, when the soft key 8b is pressed, all screen information of the CNC 51 (#1) is displayed. That is, it is possible to switch to a screen displaying information on individual CNCs.

Therefore, detailed information on each CNC can be known.

In the above description, a CRT was used as the display device, but a liquid crystal display device may also be used.

C Effects of the Invention] As explained above, in the present invention, each partial screen information from a plurality of numerical control devices is configured to be displayed simultaneously on −1 display devices, so that important information of all numerical control devices can be displayed simultaneously. can be observed and referenced simultaneously on one display device.

In addition, the configuration has been configured so that the screen can be switched to display information for each numerical control device, so normally each partial screen information is displayed, and when you want to know more details, you can switch to the screen information for each numerical control device. can be displayed. Therefore, detailed information on each numerical control device can be obtained as needed.
