JPH0486904A - Periodic check time notice method for cnc device and cnc device - Google Patents

Abstract

PURPOSE:To promote timely check by outputting timely warning with the comparison between a set value set in advance and an integrated value according to the state of movement. CONSTITUTION:The reading processing of the set time set in advance for each periodic check item and the integrated value (time) integrated according to the movement state for each item is performed to comparatively process the both time. When the integrated time excesses the set time, the warning for the periodic check is outputted. Next, when the reset operation for the integrated time is discriminated and the reset operation is recognized, the periodic check is regarded as completed, the warning is reset, and the integrated time is cleared to zero to be returned to the original processing of the CNC. Therefore, since the user is notified that the time for periodic check arrives by the warning when the item excessing the set check time is generated, failure and accidents caused by the shortage of the check can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention (Field of Industrial Application) The present invention relates to a method for notifying periodic inspection timing in a CNC machine.

(Prior Art) Machine tools equipped with CNC devices have periodic maintenance inspections determined by the manufacturer. The user inspects each inspection item according to the periodic inspection period and replaces parts as appropriate.

However, whether or not to perform periodic inspections on CNC equipment is up to the user, and for this reason, inspections may not be performed even after the periodic inspections have passed, resulting in the problem that machine failures occur due to insufficient inspections. was there.

(Problems to be Solved by the Invention) As mentioned above, although some parts of conventional regular inspections of CNC machines can be managed by the manufacturer, many parts are left to the user, and the In order to survive machining, there were problems such as having to inspect the parts after the inspection period had passed, or not inspecting them and using the parts until they were damaged, which deteriorated the accuracy of the work.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a CNC apparatus and a method for notifying a periodic inspection time in a CNC apparatus, which can prompt the user to timely inspect the periodic inspection items that should be performed on the user's side.

[Structure of the Invention (Means for Solving the Problems) To solve the above problems, the periodic inspection timing notification method for a CNC machine according to the present invention is to notify each periodic inspection time in advance for various periodic inspection items in a CNC machine. 1. Operate the CNC device while comparing the cumulative value of operating time for each inspection item with each set time, and when the cumulative value exceeds the set time, a warning will be issued to notify you of periodic inspection. The warning is output based on an operation for resetting the cumulative time, and the warning is reset, and the cumulative time is cleared.

Further, the CNC device of the present invention includes a storage section in which each periodic inspection time is stored and set in advance for various periodic inspection items on the user side, and a cumulative value of operating time for each inspection item is compared with each set time. a warning output unit that outputs a warning to notify of periodic inspection when the integrated value exceeds the set time; and a warning output unit that resets the warning based on the integrated time reset operation and clears the integrated time. A warning reset section is provided.

(Function) According to the periodic inspection timing notification method for a CNC device and the CNC device of the present invention,
By comparing with the ζ integrated value, a warning can be outputted from the CNC device itself in a timely manner.

(Embodiment) A CNC device according to an embodiment of the present invention includes a storage unit in which each periodic inspection time is stored and set in advance for various periodic inspection items on the user side, and an integrated operation time for each inspection item. a comparison unit that compares the value with each set time; a warning output unit that outputs a warning to notify of periodic inspection when the integrated value exceeds the set time; and a warning output unit that resets the warning based on the integrated time reset operation. , and a warning reset section for clearing the accumulated time. These parts are general CN
Since this is a member that can be easily added to the C device by adding software, illustration is omitted. It is assumed that the warning output section is configured to notify the contents of the notification on the screen on the CRT.

FIG. 1 is a flowchart showing the processing method of the CNC device.

In step 101, the preset time set for each periodic inspection item and the integrated value (time) accumulated according to the operating status of each item are read, and in step 102, the two times are compared. do.

If the cumulative time does not exceed the set time in the comparison at step 102, the process is ended and the process returns to the original CNC process.

Further, if the accumulated time exceeds the set time in step 102, the process moves to step 103, and a warning for periodic inspection is output.

This output is set to a value several days smaller than the actual periodic inspection time, so that it is output at the end of the CNC operation for one day, and the periodic inspection is performed before the next day's CNC operation. You can also do it.

Next, in step 104, a reset operation for the cumulative time is determined, and if there is no reset operation, the process returns to the original CNC processing, moves to steps 101, 102, and 103 again, and continues to output warnings. Further, if the reset operation is approved in step 104, it is assumed that the periodic inspection has been completed, and the warning is reset in step 105. Then, in step 106, the cumulative time is cleared to zero, and the process returns to the original CNC processing.

Figure 2 shows an example of the screen when a warning is issued.

As shown in the figure, on the screen 200, periodic inspection items such as one-month inspection, three-month inspection, mirror inspection, and battery replacement are listed, and the set time and cumulative time for each item are displayed, and the cumulative time is the set time. If the limit is exceeded, the color is reversed and a warning is issued.

As described above, in the CNC device of this example, while the power is turned on, the cumulative operating time for each inspection item is constantly compared with the set inspection time, and if there is an item whose cumulative operating time exceeds the set inspection time, it is time for regular inspection. Performs a warning process for the arrival of the message.

Therefore, if an item exceeds the set inspection time, a warning is sent to the user to notify the user that the periodic inspection period has come, thereby preventing breakdowns and accidents due to insufficient inspection. Of course, these processes do not affect the original CNC processes.

Further, the accumulated time can be determined by the operating time since the last inspection, and can be accumulated by incrementing the timer using a timer interrupt while the power is turned on.

The operating time can be cleared to zero by selecting the item to be reset on the screen 200 and entering zero in the operating time using the numeric keypad.

In this embodiment, the content of the comparison between the set time and the cumulative time is displayed on the screen 200, but the content of these screens can of course be printed out. Also,
It can be transmitted to the management department via a storage medium as appropriate, and the output results of a large number of machines can be accumulated and requested to a specialist maintenance company. By passing the contents of the screen 200 to the maintenance contractor, the lighting repair process can be carried out before the warning is issued on the screen 200, thereby extending the life of the machine and maintaining machining accuracy to the maximum. Is possible.

[Effects of the Invention] As described above, the present invention has the following effects as described in the claims.
Since it is a CNC device, it is possible to output warnings in a timely manner by comparing the preset values and the integrated values according to the operating status, and the inspection items that should be performed by the user. It is possible to encourage timely inspections, extend the life of the machine, and maintain maximum machining accuracy.
