Abstract

PURPOSE:To economize the capacity of a storage device by calling any required sub program from previously registered sub programs, automatically inserting it into an NC program, constituting the NC program again and down loading it as one NC program. CONSTITUTION:When a sub program prog 1 exists while a main program Owwww is executed, the contents of a sub program Oxxxx to be used for the prog 1 are ready out of registered sub programs Oxxxx, Oyyyy and Ozzzz or the like and down loaded through a communicating means to an NC 10. When the sub program Oxxxx is completely read out and down loaded, processing is returned to the main program Owwww again, and the main program is continuously transferred. The contents of the sub program to be used for the program are not directly stored in the NC program but only the required program is selected and read out, and down loading is performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to machining control by an NC program, and more particularly to an NC program download system for downloading an NC program from a cell controller to an NC machine.

[0002]

2. Description of the Related Art Conventionally, when machining by an NC device is performed by an NC program, there are cases where the NC program including a subprogram is downloaded to the NC device for machining. In this case, for example, the conventional NC shown in FIG.
As shown in the diagram for explaining the program download method, a plurality of subprograms are registered in advance in a storage device provided on the NC device side, and a main program in a state where the subprogram is not included in the NC device from the cell controller. to download. And when executing this downloaded main program to process,
The CPU of the NC device calls the subprogram required by the downloaded main program from the subprograms registered in the storage device of the NC device each time to execute the NC program.

[0003]

In the above-mentioned conventional NC program download method, the sub program required by the downloaded main program is changed to NC.
Since it is configured to be registered in advance in a storage device provided in the device, there is a problem that the size of a subprogram that can be registered is limited by the storage capacity of the storage device of the NC device.

Due to the above-mentioned problems, the subprogram to be registered requires a large amount of storage capacity, and the required capacity exceeds the storage capacity of the storage device of the NC device, so that the subprogram cannot be stored in the storage device. In some cases, there is no case, but as a solution to this, another NC program download method shown in FIG. 7 can be considered. In the other NC program download method, a storage device for registering a subprogram is provided on the cell controller side, and the cell controller side uses the subprogram to create an NC program including the subprogram. However, in the other NC program download method, the cell controller needs to store a long NC program including a subprogram, and thus the capacity of the storage device of the cell controller needs to be large.

Therefore, the present invention solves the above-mentioned problems of the conventional NC program download system and provides an NC program download system capable of saving the capacity of a storage device for storing the program. With the goal.

[0006]

According to the present invention, when a NC program including a subprogram is processed while being downloaded from a cell controller, the subprogram file of the subprogram used in the NC program is described in the NC program. In the cell controller, a subprogram file obtained by analyzing the NC program is used to call a required subprogram from preregistered subprograms, and the called subprogram is automatically converted into the NC program. The NC program is reconstructed by manually inserting the program and downloaded as one NC program, thereby achieving the object of the present invention.

Further, in the present invention, the NC program includes a main program and a sub program, and the description of the sub program file can be made as a comment statement described in the program. It can also be done during the program.

In the present invention, the subprogram can be called from either the main program or the subprogram.

It is controlled by the basic software.

Next, the download method of the present invention will be described with reference to the block diagram of the download method of the NC program of the present invention in FIG.

In the storage means 30 shown in FIG.
The NC program for executing is divided into a main program and a sub program and stored. The main program is stored excluding the subprogram portion of the NC program, while the subprogram used in the main program is registered in advance in a state independent of the main program. As for this sub-program, only the sub-program used in the main program of the NC program used for the NC machining may be registered, or various sub-programs including sub-programs not used in the main program may be registered. However, it is also possible to read only the required subprogram.

The main program and the sub-program are registered with names such as "O ***". In FIG. 1, the main program is named “Owwwww”, and the subprograms are “Oxxxx”, “Oyyy”, and “Ozzzz”.
It is registered under the name. Further, in the main program, for example, an annotation sentence represented by "./*****" is described, and in the annotation sentence, for example, "(./pro"
gN / O ***) ”, the comment text is“ O ***
It is defined as a comment statement that represents a subprogram named "*". The annotation statement representing the subprogram represented by “(./progN/O***)” indicates that it is the Nth subprogram in the main program, and the content of the subprogram is “O. It indicates that it is a subprogram with the name "***".

When the subprogram O *** is used in the main program or the subprogram, the subprogram file O ** described by the comment sentence "(./progN/O***)" is used. *** indicates the start of quoting to the subprogram O ***, and “M98P ***” indicates the end of quoting of the subprogram. In addition, the referenced subprogram is "O ***" at the beginning and "M99" at the end.
As for the execution of the program, "(./progN/O*
After proceeding to the first line of "O ***" after the comment sentence of "***)" to process the subprogram, the process returns from the last line of "M99" to the line of "M98P *****".

(Operation of Embodiment of the Present Invention) The cell controller 20 first downloads a main program (a program represented by "Owwww" in the drawing) of the NC program in order. In this download, the unit of data to be communicated differs depending on the communication protocol used, and is not necessarily performed in units of program lines. The program transferred by this download is temporarily stored in the storage memory in the NC device 10, and sequentially executes the NC device.

During execution of the main program Owwwww, if the subprogram prog1 exists, the subprogram (O
xxxxxx, Oyyy, Ozzzz, ...), reads out the contents of the subprogram Oxxxx used in the subprogram prog1 (in FIG. 1), and communicates the contents of the subprogram in the same manner as the main program Owwwww. Download to the NC device 10 via the means 40. When the reading of the sub-program Oxxxx and the subsequent download are completed, the program returns to the main program Owwwww (in FIG. 1) again, and the transfer of the main program Owwwww is continued.

Subprogram Ox read out above
If another sub-program Ozzzz is present in xxx, the reading of the sub-program Oxxxx is suspended, the other sub-program Ozzzz is read from the sub-program Oxxxx (in FIG. 1), the main program Owwwww, and the sub-program The program is downloaded to the NC device 10 via the communication means 40 in the same manner as the program Oxxxx. When the reading and transfer of the subprogram Ozzzz are completed, the process returns to the subprogram Oxxxx again (in FIG. 1), and the download of the subprogram Oxxxx continues.

Furthermore, the following main program Oww
While executing ww, another subprogram prog2
Is present, the subprograms (Oxxxxx, Oyyy, Ozzzz, which are registered in the storage means 30 are stored.
From z, ...), the contents of the subprogram Oyyy used for the subprogram prog2 are read (FIG. 1).
The contents of the sub-program in the same manner as the main program Owwww, and N
Download to C device 10. The subprogram O
When the reading of yyyy and the subsequent download are completed, the main program Owwwww is returned again (in FIG. 1), and the transfer of the main program Owwww is continued.

Therefore, in the NC program downloading method of the present invention, the main program and the sub-program do not directly store the contents of the sub-program used in the program in the NC program, but the sub-program in the main program. Only an index such as a subprogram for specifying a program is described, and a required subprogram is selected from the previously registered subprograms, read out, and downloaded.

Next, the operation procedure of the NC program download method of the present invention described above will be described with reference to the flowchart of FIG. 4 for downloading the NC program of the present invention and the flowchart of FIG. 5 for reading the subprogram of the NC program of the present invention. Will be explained.

First, the operation procedure for downloading the NC program will be described with reference to FIG.

Step S1: The cell controller detects the presence / absence of an annotation sentence in the main program before starting the download of the main program. If there is an annotation sentence in the main program, the process proceeds to step S5, and if there is no annotation sentence in the main program, the process proceeds to step S2.

Step S2: In the above process, when there is no comment text in the main program at the time of starting the download of the main program, the transfer of the program is started and the download is performed. The NC device 10 executes NC processing according to the downloaded program. In order to adjust the processing speed of the NC device 10 and the download timing of the program, the downloaded program is once stored in the storage device, and the contents of the stored program are sequentially executed. As a result, the program can be downloaded regardless of the processing speed of the NC device 10.

Step S3, Step S4: In the sequential transfer of the main program, the presence or absence of the comment sentence in the main program is detected. If there is a comment sentence in the main program, the process proceeds to step S5 and the comment is made in the main program. If there is no sentence, the download of the main program is continued and the download is performed until the end of the main program.

The end of the main program can be detected, for example, by describing a code indicating the end of the main program such as "M99" in the end line of the main program and detecting the end code.

Step S5: In the step S1 or S3, if the main program has an annotation sentence, it is determined in this step whether or not the annotation sentence is an annotation sentence representing a subprogram.

The comment text in the main program includes a comment text that represents a simple comment and a comment text that represents a citation of a subprogram. In this step, only the comment text that represents a citation of a subprogram is selected. In this step, if there is no comment text indicating the citation of the subprogram, the main program in step S2 is downloaded.
On the other hand, if there is an annotation statement indicating the citation of the subprogram in this step, the process proceeds to step S6 to read the subprogram.

Step S6: In this step, the subprogram is read and the read subprogram is downloaded in the step S2. The reading of the subprogram is performed by selecting the subprogram indicated by the subprogram file in the annotation text from the subprograms registered in advance and reading the contents of the subprogram.

The operation of reading this subprogram will be described below with reference to the step T using the flowchart for reading the subprogram of the NC program of FIG.

Step T1: The cell controller detects the presence / absence of a comment sentence in the subprogram before starting the download of the subprogram. If there is a comment sentence in the subprogram, the process proceeds to step T5, and if there is no comment sentence in the subprogram, the process proceeds to step T2.

Step T2: In the above process, when there is no comment text in the subprogram at the start of downloading the subprogram, transfer of the subprogram is started and download is performed in the same manner as transfer of the main program. . The NC device 10 continues the NC processing according to the downloaded subprogram. Like the main program, the downloaded sub program is once stored in the storage device, and the contents of the stored program are sequentially executed to perform NC processing. As a result, the subprogram can be downloaded regardless of the processing speed of the NC device 10.

Step T3, Step T4: In the sequential transfer of subprograms, the presence or absence of comment text in the subprogram is detected. If there are more comment texts in the subprogram, the process proceeds to step T5, and the subprogram If there is no comment text, the download of the subprogram is continued, and the download is performed until the end of the subprogram.

As with the detection of the end of the main program, the detection of the end of the subprogram is performed by writing a code indicating the end of the subprogram such as M99 in the end line of the subprogram and detecting the end code. It can be carried out.

Step T5: In the step T1 or T3, if there is an annotation statement in the subprogram, it is judged in this step whether or not the annotation statement is an annotation statement that cites another subprogram. I do.

Similarly to the comment text in the main program, the comment text in the subprogram includes a comment text that represents a simple comment and a comment text that refers to a citation of another subprogram. Select only annotations that represent program citations. In this step, if there is no comment text indicating the citation of another subprogram, the subprogram in step T2 is downloaded.
On the other hand, if there is an annotation statement indicating the citation of another subprogram in this step, the process proceeds to step T6 to read the other subprogram.

Step T6: In this step, another subprogram is read, and the read subprogram is downloaded in step T2.

Further, when there is another subprogram in the subprogram, the other subprogram is downloaded according to the flowchart of the subprogram described above.

(Effect of Embodiment) According to the embodiment of the present invention, since it is not necessary to store the subprogram in the storage device of the NC device, the storage capacity of the storage device of the NC device can be saved. Moreover, since it is not necessary to create a long NC program including a subprogram in the cell controller, it is possible to save the storage capacity of the storage device on the cell controller side.

[0045]

As described above, according to the present invention,
In the NC program download method, the capacity of the storage device for storing the program can be saved.
