Abstract

PURPOSE:To simplify program input operation by reading out a program from a program recording medium and storing a label number read out from the program by an analyzing means in a program input storing means to input the program. CONSTITUTION:The analyzing means 11 receiving a program input request command commands an input device control means 4 to start a program input device 3. The device 3 reads out programs successively from a paper tape 2. The analyzing means 11 decides whether a label number set up by a keyboard 1 exists or not at the time of reading out a label number in the program read by the device 3. When the label number exists, the means 11 stores the program read by the device 3 in the program input storing means 8 through an input device control means 4 to complete program input. Thus, the program input operation can be simplified.

It is.

Next, the operation of the conventional numerical control device will be explained based on the flowchart shown in FIG.

First, in step SL, the label number of the program to be input is set using the keyboard (1).

At this time, the keyboard (1) is connected to the label number setting means (1).
Functions as a). In step S2, the keyboard (1
) is used to issue a label number search command to the analysis means (5) to search for a label number from the paper tape (2). At this time, the keyboard (1) functions as a label number search command means (tb). Upon receiving the search command, the analysis means (5) instructs the input device control means (6) to start the program input device (3) in order to search for the label number.

In step S3, the program input device (3) reads the label number from the paper tape (2). In step s4, the analysis device (5) determines whether the label number read by the program input device (3) matches the program label number set by the keyboard (1). If the label numbers do not match, step S5
Step S is performed while the end of the tape is not being read.
Repeat steps 3 and 84. On the other hand, if the label numbers match, the search for the label number ends and the process goes to step S6, and the display data creation means (7
) and display the data on the display device (6).

In step S7, after confirming the completion of the search on the display device (6), the program input of the desired program having the set label number is requested using the keyboard (1). At this time, the keyboard (1) functions as program input command means (1c). In step s8,
Analysis means (5) that receives the program input request command

The program input device (3), which has been instructed to start the input, inputs the program to be inputted by the input device control means (4) and inputs the program to the program input storage means (
8) and complete the program manually.

Note that while the tape end is not read in step S5, steps S3 and 84 are repeated, and if the label numbers do not match and the tape end is read, the program ends without inputting the program.

In addition, if it is desired to input a plurality of programs, after the program input in step S8 is completed, the label number of the program to be manually input must be set and corrected again using the keyboard (1).

[Problems to be Solved by the Invention] In the conventional numerical control device as described above, before performing a program input request operation, a search request operation is performed to search the program recording medium for the label number of the program to be input. Moreover, when a user wants to select and input a plurality of programs, the search request operation and the program input request operation must be repeated, making the operation cumbersome.

This invention was made to solve this problem, and it is possible to search for and input a set label number simply by requesting program input, and it is also possible to select multiple programs with a single operation. The purpose is to obtain a numerical control device that can input data.

[Means for Solving the Problems] A numerical control device according to the present invention includes a program recording medium in which a plurality of programs are registered, a label number setting means for setting a label number, and a program input device for requesting program input. A command means, a label number storage means for storing the label number set by the label number setting means, a program input device for reading and manually inputting the program registered in the program recording medium, and activating the program input device. In response to a program input request command from the program input command means, a command is issued to the input device control means to start the program input device, and the program manual input device inputs the program from the program recording medium. Analyzing means for sequentially reading label numbers from the program, determining whether or not there is a label number stored in the label number storage means, and storing the program in the program input storage means if there is a label number. It is configured to include the following.

[Function] In the present invention, the label number setting means sets the label number of the program to be manually executed, the label number is stored in the label number storage means, and the program manual command means performs the operation requested by the program manually. The program is sequentially read from the program recording medium by the program input device, and when the label number is read from the program, the analysis means determines whether or not there is a label number stored by the label number storage means, and if there is a label number. In this case, the program is stored in the program input storage means and the program is input.

[Example code] FIG. 1 is a block diagram showing one embodiment of the present invention.

) is a program input storage means for storing a program to which the label number set is to be inputted; (10) is a label number storage means for storing the label number set by the label number setting means (la); and (11) is an analysis means. The means issues a command to the input device control means (4) to start the program input device (3) in response to the program input request command from the program input command means (lb), and the program input device (3) executes the program input. A program is sequentially read from a recording medium (2), and when a number is read from the program, it is determined whether or not there is a label number stored by a label number storage means (10). (12) is a CPU having input device control means (4) and analysis means (11)
It is. .

Next, the operation of the above embodiment will be explained based on the flowchart of FIG.

At this time, the keyboard (1) functions as program input command means (lb). The analysis means (11) that received the program input request command is the input device control means (4).
to start the program input device (3). In step S3, the program input device (3) sequentially reads programs from the paper tape (2). Step S4
Then, the analysis device (11) determines whether or not the label number set by the keyboard (1) exists when the program input device (3) reads the label number in the program read. If there is no label number, the process will continue until the end of the tape is read in step S6.
Repeat steps S3 and 84. On the other hand, if there is a label number, in step S5, the analysis means (11) causes the human-powered device control means (4) to store the program read by the program input device (3) in the program input storage means (8). , program input is completed.

In addition, if you want to input multiple programs, set the label numbers of the multiple programs using the keyboard (1), and store the multiple label numbers in the label number storage means (10).
When the operations from step S3 to step s5 are completed for one program, the operations from step S3 to step S5 are sequentially performed for the next program and stored in the label number storage means (10). The operations from step S3 to step s5 described above are repeated for the number of label numbers, and the input of a plurality of programs is automatically completed. Therefore, there is no need to perform a request operation to search for a label number as in the past, and it is now possible to input any number of programs with fewer operations than in the past.

In the above embodiment, the input medium was a paper tape (2), but other input media or program data output from another numerical control device may be used.

Furthermore, in the above embodiment, the case of the program input function was explained, but if the medium for selecting the program is the memory in which the program is registered in the numerical control device, and the set label number is registered in the memory, then , if the program is outputted, the same effect as in the above embodiment can be achieved with the program output function.

[Effects of the Invention] As explained above, in this invention, the label number setting means sets the label number of the program to be input, the label number is stored in the label storage means, and the program input command means requests the program manually. The program is read sequentially from the program recording medium by the program manual device, and when the label number is read from the program, the analysis means determines whether or not there is a label number stored by the label number storage means, and the label number is If there is a program input, the program input is stored in the program input storage means and the program is executed, so there is no need to perform a request operation to search for a label number, and it is possible to input multiple arbitrary programs with fewer operations than before. This has the effect of making the operation extremely simple.
