DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a machine tool maintenance management device for managing the execution timing of maintenance work such as oiling and cleaning on a machine tool.

(b), Prior Art FIG. 5 is a diagram showing a name plate indicating the timing of execution of conventional maintenance work.

Conventionally, the timing of this type of maintenance work has been simply indicated by pasting a name plate 12 as shown in FIG. 5 at an appropriate location on the machine tool.

(C) 6 Problems to be Solved by the Invention However, in this case, maintenance work is left to the autonomous management efforts of the operator, and the operator is distracted from the actual machining work, This resulted in the inconvenience that the machine tended to forget about certain tasks, which in turn had a negative impact on the accuracy and life of the machine.

In order to eliminate the above-mentioned drawbacks, the present invention aims to provide a machine tool maintenance management device that can perform maintenance work on a machine tool at accurate time intervals without the operator's independent management efforts. This is the purpose.

(d) Means for Solving the 8 Problems That is, the present invention has a display unit and a memory that stores a machine management table indicating the content of maintenance work and the time interval at which the content of the work should be performed. , a time measuring means for measuring and accumulating the operating time of the machine tool is provided, and from the measurement result from the time measuring means and the time interval for each work content in the machine management table, it is determined that the operating time exceeds the time interval. a time determining means for determining whether or not maintenance work is being performed, and a notification instruction means for notifying on a display unit that it is time to perform maintenance work based on a determination result by the time determining means. .

(e) 0 effect With the above configuration, when it is determined that the operating time of the machine tool has reached the time interval specified for each work content shown in the machine management table, the present invention displays a message on the display section. It acts to indicate that it is time to perform maintenance work.

(f), Example Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a system block diagram showing an example of a machine tool maintenance management system according to the present invention, FIG. 2 is a flowchart showing an example of a machine management program, FIG. 3 is a diagram showing an example of a machine management table, and FIG. 4 FIG. 3 is a diagram showing an example of display on a display unit.

The machine tool maintenance management device 1, as shown in FIG. A control unit 7, a machine management file 9, an input device 10 such as a keyboard, a display unit 11 such as a display, etc. are connected.

Since the machine tool maintenance management device 1 has the above configuration, when the machine tool maintenance management device 1 performs maintenance management of a machine tool, the main control unit 2 loads the machine management program MMP from the system program memory 3. The machine tool is managed based on the machine management program MMP. That is, as shown in FIG. 2, the machine management program MMP instructs the operator in step S1 to
The user is prompted to input the time MT to be managed for various management items. The main control unit 2 controls the time MT input by the operator.
is stored and set as the setting time TIM of the corresponding item in the machine management table TBL stored in the machine management file 9. As shown in Fig. 3, the machine management table TBL shows the items to be managed in the machine tool, and includes a set time indicating the time interval at which maintenance work should be performed for each work location wp and work content CW. TIM is set and the time M input by the operator via the input device 10
T is stored as this set time TIM. Further, in the machine management table TBL, for each work content CW, the previous work date DATE and the operating time DT from the previous work to the present are recorded. Note that the operator can operate the input device 10 to call up the machine management table TBL in the machine management file 9 on the display unit 11 as appropriate, and check the management status of the machine at that point in time.

In this way, when the operator has set the set time TIM for each management item in the machine management table TBL, the machine management program MMP enters step S2 and sends the time measurement control section 7 each work content CM of the operating time of the machine tool.
Commands the measurement integration operation for each time. In addition, the machine management calculation unit 5
In step S3, the operating time for each work content CM measured by the time measurement control unit 7 is compared with the set time TIM for each work content CW set in the machine management table TBL, and the operating time is set. Determine whether time TIM has been reached. Note that the measurement results by the time measurement control unit 7 are also output to the machine management control unit 6, and the machine management control unit 6 calculates the operating time DT for each work content CW in the machine management table TBL by measuring the operation time DT in the time measurement control unit 7. It is updated based on the integration result so that the working time DT of the work content CW displays the actual working time.

Further, if the operating time has not reached each set time TIM in step S3, the process returns to step S2 to continue measurement by the time measurement control section 7, and the operating time reaches the set time TIM.
If M has not been reached, the process proceeds to step S4, where the machine management control section 6 displays a message on the display section 11 informing that it is time to carry out maintenance work, and also displays the machine information in the machine management file 9. A flag FLG is set at the address in the management table TBL where the corresponding operating time DT whose operating time has expired is stored, to indicate that fact (in Fig. 3, a frame is placed around the number indicating the corresponding operating time DT). ).

In response to this, the operator operates the input device 10 in step S5 to call up the machine management table TBL on the display unit 11, and learns which part of the machine tool should undergo maintenance work. On the display unit 11, the machine management table TBL displays the work content CW with the flag FLG in a reverse display or a flashing display, for example, so that the work content CW with the flag FLG can be identified. Content CW can be recognized. At this time, based on the operator's instructions via the input device 10, as shown in FIG. You can also do that.

In this way, the operator performs the predetermined maintenance work based on the machine management table TBL etc. displayed on the display unit 11, and when the work is completed, an instruction to complete the work is sent from the input device 10 to the main control unit in step S7. Do this for 2.

Then, in step S8, the main control unit 2 sets the operating time DT for the corresponding work content CW in the machine management table TBL of the machine management file 9 and the time integrated value corresponding to the work content in the time measurement control unit 7 to 0. At the same time, the date in the previous work date column is updated to the date on which the new work was performed, and the process returns to step S2, where the time measurement control unit 7 restarts the measurement of the operating time for the work content CW.

In addition, although the above-mentioned embodiment described the case where the machine tool maintenance management device 1 is used alone, the machine tool maintenance management device 1 can be used not only alone but also incorporated into a numerical control device that controls a machine tool. Of course, it may also be provided in the form of a shape.

(g). Effects of the Invention As described above, according to the present invention, the display unit 11 and the machine management table showing the work content CW to perform maintenance work and the time interval at which the work content CW is to be performed in the set time TIM, etc. A time measurement means such as a time measurement control section 7 having a memory such as a machine management file 9 storing the TBL and measuring and accumulating the operating time of the machine tool is provided, and the measurement results from the time measurement means and the machine management table are provided. A time determination means such as a machine management calculation section 5 or the like is provided for determining whether or not the operating time exceeds the time interval based on the time interval for each work content CW in the TBL, and the determination result by the time determination means is Based on this, we have provided a device on the display section 11 to notify that it is time for maintenance work + a notification instruction means such as the Jft management control section 6, so that maintenance and inspection work on machine tools can be carried out at accurate time intervals. This makes it possible to provide a highly reliable machine tool maintenance management device 1 that does not depend on the operator's independent management efforts.

Furthermore, it is possible to prevent a decrease in accuracy and life of the machine tool due to forgetting maintenance work.
