Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention provides a faulty machine repair instructing device that instructs which working machine should be repaired when a failure occurs in a plurality of working machines having the same function. Regarding.

[Technical background of the invention and its problems]

Conventionally, in this Yuzu repair instructing device, when a failure occurs in a working machine, a rung, a feeder, etc. provided corresponding to the working machine is operated to notify the operator.

However, with this kind of machine, if all the working machines break down and stop at the same time, the operator has to rely on his/her intuition as to which working machine should be restarted at the same time. If a machine with a breakdown that takes 10 minutes to repair and a machine with a breakdown that takes only 1 minute to repair are stopped at the same time, the operator cannot judge the time after repair, so start with the machine that will take 10 minutes to repair. (There may be cases where li'ffl is started. With such a gift, one working machine will be stopped for 10 minutes, and the other working machine will be stopped for 11 minutes, so the total downtime of the two machines will be 21 minutes.) .

On the other hand, if the work machine that takes only one minute to repair is repaired, the total downtime of the two machines will be 11 minutes.

As described above, in the past, even if a working machine malfunctioned, it was not possible to determine the repair time, so there was a risk that the machine would be stopped for a long time, and there was a problem that the operating rate of the machine would decrease.

[Purpose of the invention]

This invention was made in order to solve such problems, and its purpose is to provide a repair instruction device for a broken machine that can efficiently repair a broken working machine and improve the operating rate of the machine. do.

[Summary of the invention]

This invention provides a plurality of types of failure detection means for each of the counting work machines having the same function, and stores repair time information set in advance in response to various failures of the work machines in a repair time memory.

Read H7 from ROM 26 and add it to C memory.

Next, find the absolute value of the difference between the sandal number 9 of the most recently repaired work machine stored in NOCMIN and the sample number of the B-th work machine just checked stored in B memory, and then write WEIG from ROM26. Multiply J is read out and multiplied. In other words, this is B, which was checked just now assuming that the operator was standing in front of the working machine that was repaired last time.
The time required for the operator to move to the second work machine is calculated. The result of this multiplication is stored in memory A, and then the contents of memory A and the contents of memory C are added and stored back in memory C. That is, this means that the time required to repair the B-th work machine is determined based on the total time of the repair time due only to the failure and the travel time of the operator.

Next is BFC MIN K. The highest/J stored so far
Compare the S repair time information and the B-th work machine's repair time + information stored in the C memory, and if the C memory is smaller, change the contents of BFCMIN to the contents of the 2c memory, In addition, the contents of the B memory are also stored in the D memory. Next B
The sample NO0 in the memory is subtracted by one, and if the result is not zero, a similar check is made for the failure of the work machine with one less sandal N020. Then, if the content of B memory is subtracted by 1 and becomes zero, it is the sample number of D memory.
is stored in NOCIMIN and the failure check is completed.

When the failure checking process is completed, the CPU Z 3 sets the repair time of BFCMIN in the gold counter as shown in FIG. Control. After that, during repair, 1 uJ t f: Check for failures of the working machines other than the working machine for which the lamp 1 was turned on while counting down. This failure check is the processing content shown in FIG. Then, when 5jJ t becomes zero at the time of repair, it is checked whether the repaired working machine is operating by checking Bit<o>, and if it is operating, this process is terminated, and if it is not operating, other If there is a working machine that is out of order, the buzzer 12 of the working machine that is currently being repaired is activated to notify the operator that the scheduled repair time has elapsed, and if there is a working machine that is out of order, Control is performed by lighting up the rung 1 of the other working machines to notify the operator. With this configuration, n working machines J-J to l-n
Even if multiple of these work machines fail at the same time, the machine that requires the least amount of time for the operator to go from the position of the work machine that was most recently repaired to the position of the malfunctioning work machine and repair it is designated by Runf°J1. be done. The operator can then go to the location on the work machine where the time required for repair is the shortest and carry out the repair work. When the repair work on this machine is completed, the lamp 11 of the working machine that will be moved from that position and has a short repair time per repair is illuminated and instructed. Therefore, for example, if all the working machines 1-1 to 1-n are set up at intervals of, for example, 30 seconds of movement time, and the operator is now at the position of the core 1-4, the machines 1-3. l-
If a failure occurred at 5°1-6, and the repair times for each failure were 1 minute, 10 minutes, and 1 minute, then IBj, taking into account travel time, would be 1 minute and 30 seconds.

10 minutes and 30 seconds, which becomes 2 minutes. Then, the lamp 1 of the working machine 1-3 lights up, and the operator goes to the machine 1-3 and performs repair work.

When the repair of work machine 1-3 is completed, the repair time for the remaining work machines 1-5 and 1-6 will be 11 minutes and 2 minutes and 30 seconds, so work machine No. 6 will be repaired next.

Finally, the work machine 1-5 is repaired, and the repair of all the broken work machines 1-3, 1-5 and 1-6 is completed.

The total repair work time required at this time is 1 minute 30 seconds + 2 minutes 3
The total time is 14 minutes and 30 seconds (0 seconds + 10 minutes and 30 seconds), and the total amount of time the machine is stopped can be minimized, and a decrease in the operating rate of the machine can be prevented as much as possible.

If the working machine 1-3 is not repaired even after the repair time of 1 minute and 30 seconds has elapsed, the buzzer 12 of the machine 1-3 will sound to notify the operator. Therefore, confirmation can be made even if the operator is immersed in repair work. Then, the lamp 1 of the working machine 1-6 lights up, so the operator can temporarily interrupt the repair work on the working machine 1-3 and shift to repairing the working machine 1-6.

In addition, the operation of each working machine 1-1 to l-n is controlled by the conbeater 4.
Since it is managed collectively, CRT is connected to Combita 4.
It is also easy to connect a display to inform the person in charge of the operating status of all machines.
