Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention relates to a numerically controlled machine tool capable of recording the operating status of the machine tool and further outputting the record to the outside in the form of a hard copy.

(bl, Background of the Technology) Recent machine tools are becoming more and more capable of operating unmanned for long periods of time.
Needless to say, in addition to the structural durability of the machine, advanced operation management functions are also required.

1c)-, Conventional technology and problems In conventional numerically controlled machine tools, all operation record information such as alarm information, machining time information, and number of machining pieces are only displayed temporarily on the display, so they cannot be used for long periods of time. Hourly operation record information can only be obtained by an operator visiting each machine tool at regular intervals and writing down the operation record information currently displayed on the display of each 4Mt machine in a notebook, etc. This method is extremely inconvenient, and also lacks sufficient reliability due to the possibility of transcription errors.

(d)0Object of the Invention The present invention, in order to eliminate the above-mentioned drawbacks, provides a highly reliable numerically controlled machine tool that allows an operator to obtain long-term operation record information at any time. The purpose is to

(e) Configuration of the Invention That is, the present invention provides a memory for storing driving record information generated during driving, and outputs a hard copy that can output the driving record information stored in the memory. It is constituted by providing means.

(f) 6 Embodiments of the Invention Hereinafter, embodiments of the present invention will be specifically described based on the drawings.

FIG. 1 is a control block diagram showing one embodiment of a numerically controlled machine tool according to the present invention, and FIG. 2 is a diagram showing a display mode of operation record information on a hard copy.

The numerically controlled machine tool 1, as shown in FIG.
,! A transcription buffer memory 9, a printer 10, an axis control section 11, a tape puncher 12, etc. are connected, and a mechanism section 13 is connected to the axis control section 11.

Since the numerically controlled machine tool 1 has an imaginary configuration,
During machining, based on the operator's machining start command MS from the keyboard 6 or the like, the main control unit 2 reads out the cannibal program PRO stored in the cannibal program memory 7 and sends the corresponding nib program PRO to the shaft side mgii. commands based processing. The axis control unit 11 is a Kani program PRO.
Based on the contents of the commands, the mechanism section 13, that is, the main spindle, tool magazine, table, etc., is moved and driven to perform predetermined machining.

At this time, if any failure occurs during machining, the main control unit 2 will control the part where the failure occurred (axis control unit 1
1 and others) is displayed on the display 5, and the content corresponding to the alarm signal ARM is stored in the driving record buffer memory 9 along with the time when the alarm signal ARM was generated.
Stored as alarm information AI in driving record information DIR.

Furthermore, the main control section 2 is the axis control section 1 of the Kani program PRO.
Monitor the execution status according to 1, and convert the processing information MI such as when, what kind of workpieces were processed and how many pieces to the operation record information DI.
It is stored in the driving record buffer memory 9 as R.

In this way, all the errors that have occurred since the numerically controlled machine tool 1 started machining are stored in the operation record buffer memory 9! , information AI, processing information Ml, etc. are stored and saved as driving record information DIR. Therefore, driving record information D1. At the appropriate time when R is needed, press keyboard 6.
When the main controller 2 is instructed to output a hard copy of the driving record information 1) IR via the driving record buffer memory 9, the main controller 2 reads the driving record information I) IR stored therein from the driving record buffer memory 9. , drives the printer 10 or tape puncher 12, and outputs the read driving record information DIR as a hard copy. Can the operator obtain the driving record information output as the hard copy? li! L
) By looking at the IR, it is possible to accurately grasp the operating status of the numerically controlled machine tool 1 from the start of machining until now. FIG. 2 shows an example of the output from the notebook copy 15 of the driving record information DIR from the printers 1 and 0. Driving record information in the case of B 1) Only IRζ and alarm information AI, but according to the needs of the operator, the driving record information DIR can be collected and divided into alarm information AI and processing information Ml. Of course, output is also possible.

In the above embodiment, the driving record information DIR in the driving record buffer memory 9 is output from a hard copy output means such as the printer 1o or the tape puncher 12 according to an instruction from the operator. Of course, it is possible to advance the output of the driving record information Dlr from the output means as soon as the driving record information IR in the driving record buffer memory 9 becomes full. Furthermore, the memory for recording driving record information DII't is R.
In addition to AM (random access memory), it is also possible to use appropriate memories such as floppy disks and cassette magnetic tapes.

(g) 3 Effects of the Invention As explained above, according to the present invention, driving record information DI such as alarm information generated during driving and processing information M1, etc.
A printer 1o is provided with a memory such as a driving record buffer memory 9 for storing and storing R, and is capable of outputting driving record information DIR stored in the memory as a hard copy.
, a hard copy output means such as a tape puncher 12 is provided.The operator can output the operation record information DIR from the output means as a hard copy 15 at any time, thereby controlling the operating state of the numerically controlled machine tool 1 at any time. It becomes possible to keep track of the time of day, and by going around every predetermined time and transcribing the driving record information from the display, there is no need for complicated and unreliable work, and it is possible to unmanned processing. This makes it possible to provide advanced management functions to the numerically controlled machine tool 1.
