Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a program display device, and more particularly, to a numerical control device for controlling a controlled object in parallel, for example, two or more blades composed of two or more spindles. The present invention relates to a display device for displaying a machining program for a multi-axis lathe having a table.

[Prior Art] FIG. 4 is a block diagram of a conventional numerical control device for operating controlled objects in parallel according to a plurality of machining programs.
In FIG. 4, (1) and (6) denote a first-system machining program file and a second-system machining program file storing a first-system machining program and a second-system machining program, respectively, and (2) ) And (7) are the first system machining program files (1) and
A first-system read control unit and a second-system read control unit that read the first system machining program and the second system machining program from the system machining program file (6);
(3) and (8) are a first system control command converter and a second system control command converter for converting the read first system machining program and second system machining program into control commands, respectively. ) And (9) are a first system control command output unit and a second system control command output unit that output control commands according to the operation state, and (5) and (10) drive respective controlled objects. (11) is a display control unit for displaying the first system machining program and the second system machining program, and (12) is a display device. In addition,
The control command output unit (4) of the first system and the control command output unit (9) of the second system are configured to output the control command output unit (9) of the second system and the control command output unit (9) when there is a synchronization command in the control commands. The output is waited until a synchronization command appears on one system control command output unit (4).

Next, the operation of the conventional numerical controller will be described.
First, when the first-system read control unit (2) reads one line of the first-system machining program from the first-system machining program file (1), the first-system control command conversion unit (3)
Interprets the read machining program and converts it into a format that can be easily controlled. Next, the first system control command output unit (4)
Outputs the control command to the first system drive unit (5) according to the operating state of the first system controlled object such as start and stop. Similarly, when the second-system read control unit (7) reads one line of the second-system machining program from the second-system machining program file (6), the second-system control command conversion unit (8) Interprets the read machining program and converts it into a format that can be easily controlled. Next, the control command output unit (9) of the second system sends this control command to the drive unit (1) of the second system in accordance with the operating state of the controlled object of the second system, such as starting and stopping.
0) is output.

On the other hand, the display control unit (11) displays the machining program of the first system machining program file (1) and the machining program of the second system machining program file (6) in the display device (6) in the same order as stored in the file. Display on the display screen of 12). FIG. 5 is a diagram showing a display screen of the display device (12). FIG. 5 shows that B1 is the title of the first system machining program, B2, B3, B4, B5 and B6 are the first system commands, and B7 is the second system command.
Title of system machining program, B8, B9, B10, B11 and B1
2 is a command of the second system.

In this case, the control command output unit (4) of the first system and the second
The control command output unit (9) of the second system and the control command output unit (9) of the second system receive the synchronization command in the machining program of the first system and the machining program of the second system, respectively. The output unit (4) waits until a synchronization command appears in the control command. That is, the first system synchronization command and the second system synchronization command always execute the respective machining programs at the same time, no matter how the mutual temporal relationship is shifted before the synchronization command appears.

[Problems to be Solved by the Invention] When the conventional numerical control device having the above configuration has a synchronization command during operation and waits for each other as described above, it is the next step after the synchronization commands B3 and B10. The start of the execution of the machining programs of B4 and B11 is synchronized with the actual operation.

However, in the display screen, since the display is performed in the order stored in the machining program files (1) and (6) in order from the front, the display after the synchronization command is shifted,
There is a problem that it is difficult to grasp the interrelation between the machining program of the first system and the machining program of the second system.

Further, in order to grasp the interrelation between the machining program of the first system and the machining program of the second system, even if an attempt is made to search for the synchronization command by looking at the machining program, what is required in the machining program having many synchronization commands. There is a problem that the synchronization command may be overlooked when counting whether it is the second synchronization command.

The present invention has been made in order to solve the above-described problems, and that the meeting is performed in actual driving,
An object of the present invention is to provide a display device capable of confirming a state of parallel operation on a display screen by displaying the display operation in an easily understandable manner.

[Means for Solving the Problems] The display device according to the present invention displays the same number of control programs for controlling at least two or more controlled objects in parallel on the screen of a single display device in parallel. In the control program display device, a program reading means for sequentially reading the plurality of control programs stored in advance for each step, and the steps of the control program read by the program reading means correspond to steps in another control program. A synchronization command detecting means for detecting whether each of the plurality of read control programs is a synchronization command for instructing the start of execution in synchronization with, and when the synchronization command is not detected from any of the plurality of read control programs, The control programs are displayed in parallel in a row for each step, and one of the read control programs is displayed. When the synchronization command is detected from the control program, the display of the corresponding control program is displayed as a blank line until all the synchronization commands in the other control programs corresponding to the synchronization command are detected, and all the corresponding synchronization commands are displayed. And a display control means for displaying all the detected synchronization commands in parallel on the same line at the time of detection.

[Operation] In the present invention, in a control program display device for displaying the same number of control programs for controlling at least two or more controlled objects in parallel on a single display device screen in parallel, Reads the plurality of control programs stored in advance sequentially for each step. The synchronization command detecting means detects whether or not the step of the control program read by the program reading means is a synchronization command for instructing start of execution in synchronization with a corresponding step in another control program. When the synchronization command is not detected from any of the plurality of read control programs, the display control unit sequentially displays the read plurality of control programs as lines in each step in parallel, and sequentially reads the read control programs. However, when a synchronization command is detected from any of the control programs, the display of the corresponding control program is displayed as a blank line until all the synchronization commands in the other control programs corresponding to the synchronization command are detected. When all the synchronization commands are detected, all the detected synchronization commands are displayed in parallel on the same line.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a numerical control device to which a display device according to the present invention is applied. In FIG. 1, parts that perform the same functions as those in FIG.
The description is omitted. In FIG. 1, (13) reads a first system machining program and a second system machining program, detects a synchronization command, and executes the first system machining program and the second system machining program synchronously. This is a synchronous display control unit that displays a message to the effect on the display device (12).

Next, the operation of the display device according to the present invention will be described with reference to the flowchart of FIG.

(1) Steps S1 to S2 The synchronous display control unit (13) reads one line (one step) of the machining program from the first machining program file (1) and the second machining program file (6).

(2) Steps S3 to S5 The synchronous display control unit (13) determines whether the first system machining program is a synchronous command and the second system machining program is a synchronous command (step S3), or the first system. If the machining program is not a synchronization command and the machining program of the second system is not a synchronization command (step S4), the read machining program is displayed on the display device (12) as it is (step S5). That is, as shown in FIG. 3, if the machining program of the first system is the synchronization command B3 and the machining program of the second system is the synchronization command B10, "N2 !;" and "N3 !;" Will be displayed. Further, the first system machining program is a command B1, B2, B4, B5 or B6 other than the synchronization command, and the second system machining program is a command B7, B8, B9, B11 or B12 other than the synchronization command.
If so, the command is displayed as it is.

(3) Steps S6 to S8 The synchronous display control unit (13) determines whether the first system machining program is a synchronous command and the second system machining program is not a synchronous command (step S6). A blank line is displayed at the position where the synchronization command should be displayed, and a command (a command other than the synchronization command) of the second machining program is displayed (step S7). Next, the next time the first processing program is read, the read pointer is returned so that the same processing program, that is, the synchronization command is read again (step S8).

(4) Steps S9 to S10 The synchronous display control unit (13) performs the first system machining when the first system machining program is not a synchronous command and the second system machining program is a synchronous command (step S7). A command of the program (a command other than the synchronization command) is displayed, and a blank line is displayed at a position where the synchronization command of the machining program of the second system is to be displayed (step S9). Next, when the second processing program is read next, the read pointer is returned so that the same processing program is read again (step S10).

(5) Step S11 The synchronous display control unit (13) repeatedly executes steps S1 to S11 until the number of displayable rows of the display device (12) is satisfied, and matches the controlled object whose queuing is controlled by the synchronous command. Display screen is obtained. In FIG. 3, B13 indicates that the synchronization signal of the first system is detected,
The synchronization signal of the system is a blank line for waiting when the synchronization command has not yet been detected, and B3 and B10 are two synchronization commands at the time when the synchronization command of the second system corresponding to the synchronization command of the first system is detected. Are displayed on the same line. Therefore, the B4 of the first system displayed in the next step of these two synchronization commands
It can be easily understood that the execution of the machining program of the second system and the execution of the machining program of the second system B11 are started in synchronization.

In this embodiment, the display of the machining program in the two systems of the first system and the second system has been described.
Even when many types of machining programs are displayed in parallel, the same processing as in the present embodiment can be performed only by increasing the types of machining programs to be processed.

Further, in this embodiment, the machining programs of the two systems are displayed in parallel on one surface of the display screen. However, the screens may be displayed separately or switched and displayed.

[Effect of the Invention] As described above, according to the present invention, a control program for displaying the same number of control programs for controlling at least two or more controlled objects in parallel on a single display device screen in parallel. In the display device, the plurality of control programs stored in advance are sequentially read step by step, and the steps of the read control program indicate that the steps of the read control program start synchronously with the corresponding steps in another control program. Respectively, and when the synchronization command is not detected from any of the plurality of read control programs, the plurality of read control programs are sequentially displayed as respective lines in parallel for each step. When a synchronization command is detected from any of the read control programs, Until the point at which all the synchronization commands in the control program are detected, the display of the corresponding control program is displayed as a blank line,
At the point in time when all the corresponding synchronization commands are detected, all the detected synchronization commands are displayed in parallel on the same line. In addition to being able to be visually checked, it is easy to confirm the related steps at which synchronous execution starts after the waiting operation, and the setup time is significantly reduced.
