Abstract

PURPOSE:To dispense with meters and display devices attached to a console panel, an operation box, etc., to reduce the space by arbitrarily displaying external data from an external device, which is not directly related to an NC device, as an analog meter on the display picture of the NC device. CONSTITUTION:When a control signal to control contents to be displayed or display contents is inputted from a key input device 1, an input data processing part 2 transmits control information to a program machine control part 3 and a picture control processing part 4. External data to be displayed from the external device is inputted to and stored in an external data input part 6, and the picture control processing part 4 reconstitutes external data stored in the external data input part 6 in response to the external operation signal from the key input device 1 for the purpose of displaying the analog meter and displays a window as the analog meter on the screen of a display device 5 of the NC device. Thus, the display device requiring the attaching space is eliminated from the console panel, the operation box, or the like to reduce the space.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to a method for displaying external data in a numerical control device (hereinafter referred to as an NC device), and particularly relates to a method for displaying external data on a display screen of an NCR device. The present invention relates to an external control display method in an NC device that can display external data from an NC device.

(Prior Art) Generally, an NC device is equipped with a display device having a display screen such as a CRT screen or a liquid crystal screen. For example, FIG. 4 is a front view showing the control panel of the NC device, which includes a CRT display 5 in addition to a key-operated device 1 having various key switches. This display device 5 has N
If an external device is connected to these NC devices and only part or all of the processing content by the C device is displayed, another display device is required to display external data specific to this external device. It was necessary. The part designated by reference numeral 20 in FIG. 4 indicates a controller for external devices. In this case, when displaying external data specific to the external device, such as the current of the main shaft of the machine, load factor, rotation speed, etc., or the temperature of each part of the machine, a display device such as a meter corresponding to each data is used. It was necessary to install it on the NC device (=I). In FIG. 4, it has a meter 22 for displaying the main shaft current load.

FIG. 5 is a block diagram showing a configuration for displaying data in a conventional numerical control device. According to the figure, it is roughly divided into a display control section 10 of the NC device and a display control section 20 of the external device.

When a control number 1 for controlling the contents to be displayed and the display contents is input from the key human power device 1, the input data processing section 2 transmits control information to the program/machine control section 3 and the screen control processing section 4. .

In response to this, predetermined display contents are selected and displayed on the display device 5 between the program machine control section 3 and the screen control processing section 4.

The display control section 20 of the external device displays the display data received by the external data input 21 on an external data display 22 such as a meter. This external data display is shown in FIG. As mentioned above, it is a separate entity from the NC control device.

(Problem to be solved by the invention) In this way, when there is an external device such as a control device such as a main axis of a machine or a measuring device in addition to the NC device, it has conventionally been necessary to display external data specific to these devices. When there is
In addition to the display device of the NC device, the display was performed by attaching a meter or the like to the operation panel or operation box. Therefore, installation of display devices such as meters requires space.
There is a problem in that main operability deteriorates due to the large size of the operation panel and operation box.

In addition, it is necessary to select a display device such as a meter each time the input specifications or display specifications of an external device are changed, making the selection, arrangement, purchase, etc. of parts complicated. Moreover, since the display device must be permanently attached even for external data that does not necessarily need to be displayed all the time, the attachment not only increases space but is also economically wasteful.

Therefore, the present invention solves the above-mentioned problems and removes the display device that requires space to install from the operation panel or operation box, thereby saving space and when the need for displaying external data arises. The purpose of the present invention is to provide an external data display method with excellent operability by arbitrarily displaying data on the external data.

[Structure of the invention]

(Means for Solving the Problems) The present invention provides an external data display in the numerical control device that connects an external device to a numerical control device having a display screen, and causes the external device to display hard external data on the display screen. The method includes a first step of manually inputting external data to be displayed into an external data input section of the numerical control device in advance and storing it, and a part or all of the processing contents of the numerical control device as main screen data. a second process of configuring;
a third step of configuring the external data stored in the external data manual unit as window screen data to be displayed as an analog meter in response to an external operation signal;
When the external operation signal is off, the main screen data is displayed as an analog meter on the display screen, and when the external signal is on, the main screen data and the window screen data are combined and displayed on the display screen. It is characterized by comprising a fourth step of displaying a window on top of the screen.

(Function) According to the present invention, the external data of the external device to be displayed is inputted and stored in the external data input section of the NC device in advance, and when the external operation signal is turned on, the stored external data is It is combined with the processing content of the NC device and displayed as an analog meter in a window on the display screen that was displaying the processing content.

When you no longer need to display it, leave it outside! "By turning off the z operation signal, the window display disappears and the original display screen returns.

(Example of Length) FIG. 2 is a block diagram showing an example of an NC device for implementing the external data display method of the present invention. Referring to FIG. 5, parts that are the same as the configuration of the NC device for realizing the conventional display method described above are labeled with the same No. 7:'1.

When a control signal for controlling the contents to be displayed or the display contents is input from the key human power device 1, the human data processing section 2 transmits the control information to the program machine control section 3 and the screen control processing section 4.

In response to this, predetermined display contents are selected and displayed between the block machine control section 3 and the screen control processing section 4, and are displayed on the display device 5. At this time, external data to be displayed from an external device is manually entered and stored in the external data input section 6, and is read out to the screen control processing section 4 in response to an external operation signal from the key human-powered device.
A window is displayed on the display device 5.

In the conventional device shown in FIG. 4, the external data stored in the external data input section 6 is independently displayed on an independently provided external data display 7 without being transmitted to the screen control processing section 4. However, in the present invention, the external data stored in the external data manual unit 6 is reconfigured for analog meter display in the screen control processing unit 4 in response to an external operation (r4'j7) from the key human powered device 1. Therefore, as described above, it is possible to display a window as an analog meter on the screen of the display device 5 on the NC device.

Such an analog meter is convenient because it allows you to intuitively grasp the numerical values and status of the monitored object.

FIG. 1 shows a flowchart of screen control processing according to the present invention.

Main screen data is created for displaying part or all of the processing content by the NC device, regardless of whether external data is to be displayed (step S] 01). Then, it is determined whether an external operation signal for displaying data regarding an external device from the key-powered device 1 has been input (step 5102). If no external operation signal is input, the main screen data created in step 5101 is directly transferred to the screen of the display device and displayed (step 5106).

On the other hand, in the evening, when a 1/2* input signal is input, the data is received by the external data processing section 6, the stored data is read into the screen control processing section 4, and the data is reconfigured. The window double-sided data was also created (step 810B).
), the main screen and the window screen are combined (step 5104), and the combined data is transferred onto the screen (step 5105).

If it is necessary to continue displaying the data or other data (step 107), the process returns to step 5ID1 and the above-described procedure is repeated. If there is no need to continue displaying, the process ends.

FIG. 3 shows an example of a screen when external data is displayed using the display method according to the present invention.
A) shows the display screen 5 when the external operation signal is off, and Fig. 3 (
B) shows the display screen 5 when the external operation signal is on, and in the case of FIG. 3B, external data is displayed in an analog meter on the upper right window screen 5a.

In the example shown in FIG. 3, spindle load data (current or voltage) in a spindle control device provided outside the NC device is displayed as a spindle load factor. These external data are stored in the external data manual section 6 of the NC device prior to display. When the operation signal from the key human power device 1 is off, this external data does not appear on the display screen as shown in FIG. 3(A), but when the external operation signal is turned on, the window double-sided data is created and combined with the main screen and displayed in a window as shown in FIG. 3(B). When the external rubbing/working signal is turned off, the window showing the spindle load factor disappears and the screen returns to the one shown in FIG. 3(A).

In this embodiment, the analog meter displayed in a window appears in the upper right corner, but the window can be displayed anywhere on the screen.

Further, although the analog meter displayed in the window is a normal angular displacement type, it may also be one that changes linearly or concentrically. Display contents such as shapes, numbers, messages, etc. and display colors for these analog meters are NC.
It can be arbitrarily selected using the display program built into the device.

〔Effect of the invention〕

As described above in detail based on the embodiments, in the present invention, external data from an external device that is not directly related to the NC device is arbitrarily displayed as an analog meter on the display screen on the NC device. There is no longer a need for a meter or display device that was attached to an operation box, etc., which saves space and eliminates the need to spend man-hours on selecting, arranging, purchasing, etc. parts for display devices. Therefore, the delivery date of the product is no longer affected by the delivery date of the display equipment, and it has become possible to realize an NC device with excellent design.
