PURPOSE:To obtain an injection molding machine capable of prompting an operator to execute an inspection on a predetermined periodic inspection day by recognizing the coming of a periodic inspection day by use of a built-in clock and at the same time displaying automatically a periodic inspection display mode screen matching the kinds of the coming periodic inspection day. CONSTITUTION:Calculation control means 21 is set and stored preliminarily with each periodic inspection day and when the calculation control means 21 realizes the coming of a periodic inspection day by means of its clock 29, a main control unit 28 of the calculation means 21 makes a CRT control unit 30 display in priority a periodic inspection display mode scope corresponding to the kinds of the inspection day whatever display modes are selected therein. As the operator sets cursor to the position of inspection commencement display in a mode selection display place, the calculation control means 21 recognizies this and serves to stop the operation should the machine be in an operation state.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an injection molding machine equipped with a microcomputer that centrally controls the entire injection molding machine and a display device such as a CRT display. The present invention relates to an injection molding machine that can automatically prompt for inspection to be performed on a scheduled inspection date.

[Conventional technology] Conventionally, injection molding machines were inspected according to an inspection schedule, etc., and the operator, person in charge, etc. recognized the inspection date by themselves and performed the inspection by referring to the instruction manual, manual, etc. This method is commonly used, and the reality is that some users only perform inspections when a machine malfunction or abnormality occurs.

[Problem to be solved by the invention] As mentioned above, conventionally, operators and work supervisors themselves recognized inspection dates using schedules, calendars, etc.
Regular inspections were supposed to be performed, but some users often ignored or forgot the regular inspection dates. This may cause machine troubles.

Problems such as shortening of machine life were pointed out. In addition, it is relatively troublesome to carry out inspections by flipping through instruction manuals, etc. while referring to inspection items and specific instructions, and if the instruction manuals, manuals, etc. are lost, inspection items may become unclear. There is also the problem that proper inspection cannot be carried out. And then again, one month, six months.

Different inspection interval dates and times, such as every year (different types)
Periodic inspection dates are usually set for this type of injection molding machine, and inspection items will naturally change depending on the type of periodic inspection date, but for operators who are not used to it, monthly inspection days, 6 There was also the problem that it was difficult to know which items to inspect and how to inspect them on monthly and annual inspection days.

The present invention has been made in view of the above points, and its purpose is to provide an injection molding machine in which the injection molding machine itself can prompt an operator to carry out an inspection on a scheduled periodic inspection date. There is a particular thing.

Another object of the present invention is to display an injection molding machine that can display inspection items corresponding to the type of regular inspection date for each different type of regular inspection date and instruct the operator to perform accurate inspections. Our goal is to provide the following.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention includes a calculation processing means for controlling the entire injection molding machine, and a display device for displaying various modes based on the output of the calculation processing means. In the injection molding machine equipped with an input device, the arithmetic processing means includes:
When the arrival of a periodic inspection date is recognized by the built-in clock, a periodic inspection display mode screen corresponding to the type of the periodic inspection date that has arrived is automatically displayed to prompt the operator to perform an inspection.

[Function] As mentioned above, the arithmetic processing means of the injection molding machine itself, such as a microcomputer, uses the built-in clock (
When the arrival of the periodic inspection date is recognized by the timer (timekeeping means), the number of days corresponding to the type of the periodic inspection date that has arrived, for example, if it is a monthly inspection date, is equivalent. Further, if the inspection date is every six months, a periodic inspection display mode screen corresponding to the inspection date is automatically displayed on the display device. This allows the operator to recognize that the regular inspection date has arrived.

The situation of missing the inspection period due to forgetting the inspection date can be avoided as much as possible. In addition, since necessary inspection items are displayed according to the type of periodic inspection date, the operator can reliably recognize which items should be inspected.

In addition, by specifying the inspection items displayed on the periodic inspection display mode screen by moving the cursor on the display screen, the parts corresponding to the specified inspection items are displayed graphically and the notes are displayed in text. Following this specific guidance, even novice operators can easily and reliably perform inspection work.

In addition, when the periodic inspection display mode screen is displayed (on the periodic inspection date), for example, the inspection cannot be performed due to unavoidable circumstances related to production planning, or only a portion of the displayed inspection items are inspected due to time constraints. If the inspection cannot be carried out, the periodic inspection display mode screen will be displayed again on the next day or later by instructing to suspend one inspection. Therefore, it is possible to prompt the operator to carry out periodic inspections that do not interfere with the production schedule without forgetting the inspection date. In addition, when inspection work is performed on part of the displayed inspection items, an inspected mark will be added to the inspected items, and on the periodic inspection display mode screen that is displayed again from the next day onward, the inspected items will be marked as inspected. Inspection of unmarked inspection items is prompted. by this,
For example, even if the operator changes from the previous day, there is no risk of conducting duplicate inspections.

Furthermore, by selecting a calendar display mode that shows a list of regular inspection dates, it is possible to know in advance when the regular inspection date will arrive. In addition, in this calendar display mode, if an inspection cannot be performed on the scheduled periodic inspection date due to production planning requirements, vacation schedules, etc., the inspection date can be changed within the allowable period. be treated like this.

[Example] The present invention will be explained below with reference to an example shown in FIGS. 1 to 7.

FIG. 1 is an explanatory diagram showing an outline of an injection molding machine.

In FIG. 1, 1 is a base, and a plurality of tie bars 4 are arranged between a fixed die plate 2 and a support plate 3 installed on the base 1, and the tie bars 4 are slidably movable. A die plate 5 is inserted. A mold clamping cylinder 6 is fixed to the support plate 3, and its piston rod 6a is connected to the movable die plate 5 via a toggle link mechanism 7, and the movable die plate 5 is moved by the back and forth movement of the piston rod 6a. It moves forward or backward relative to the fixed die plate 2. Note that 8 is a fixed die attached to the fixed die plate 2, and 9 is a movable die attached to the movable die plate 5.

10 is a heating cylinder; 11 is a screw disposed within the heating cylinder 10 so as to be able to rotate and move back and forth; 12 is a hopper 13 for supplying resin material to the screw 11;
14 is a screw 11
This is an injection cylinder that controls the forward and backward movement of the machine.

As is well known, from the hopper 12 to the screw 1
The resin material supplied to the rear end of the screw 1 is mixed and plasticized by the rotation of the screw 11 and transferred forward, and as the molten resin fed is stored at the tip side of the screw 1 The screw 11 is moved backward while the pressure is controlled, and the rotation of the screw 11 is stopped when the molten resin stored on the tip side of the screw 11 reaches an amount equivalent to one shot. Thereafter, at the injection start timing after a predetermined time, the screw 11 is driven forward, and the molten resin is injected into the cavity formed by the two molds 8 and 9 which are closed (mold clamped). The pressure is maintained for a predetermined period of time. After that, the mold is opened after the resin injected into the mold has cooled and solidified, and the product (
The molded product) is taken out by a take-out machine 15 or the like provided as necessary.

16 is an injection stroke sensor, 17 is an injection pressure sensor,
18 is a mold opening/closing stroke sensor, 19 is an eject detection sensor attached to an eject mechanism for extruding the product adhered to the mold, and 20 is an ejecting gutter operation detection sensor attached to the ejecting machine 15, etc. Measurement information from each of the sensors 16 to 20 and other sensors (not shown) is sent to arithmetic control means, which will be described later, via an appropriate input conversion circuit as necessary.

21 is an arithmetic control means mainly composed of a microcomputer that controls the entire injection molding machine; 22 is an arithmetic control means 2;
1 is a key manual device for inputting various commands; 23 is a key manual device for inputting various commands;
A display device such as a color CRT display for displaying the processing results of the calculation control means 21 and display patterns created in advance; 24 a printer for printing out the processing results of the calculation control means 21; 25;
is an external storage device that exchanges data with the arithmetic control means 21 as necessary.

The calculation control means 21 includes an input/output interface 26
, an input/output conversion arithmetic unit 27, and a main control unit 128 that includes a clock 29. It is equipped with a CRT control device [130, etc., to control the automatic operation of the injection molding machine, and to display screens in various display modes on the display section W23. Here, the arithmetic control means 21 is mainly composed of a microcomputer as described above,
In reality, it is equipped with various I10 interfaces, ROM that stores main programs and fixed data, RAM that reads and writes measurement data and various flags, etc., a clock, and an MPU that controls the entire system. It is backed up by a battery. The arithmetic control means 21 controls automatic operation of the injection molding machine and displays screens in various display modes on the display device 23 based on various programs created in advance.

That is, the calculation control means 21 performs, for example, based on a molding sequence control program created in advance and setting condition values, while referring to the outputs from each of the sensors described above.
Mold opening/eject/product removal process, mold closing/retightening process, injection/holding process.

The charging process and the like are controlled and executed, and the drive source of each part of the injection molding machine is controlled by the control output signal from the input/output interface 26 through appropriate driver means.

Further, the calculation control means 21 includes the key human power means 22.
Various periodic inspection display mode screens, various condition setting mode screens, operating condition monitoring mode screens, etc. are displayed according to instructions from the computer or the judgment of the arithmetic control means 21 itself.

By the way, in an injection molding machine having such a configuration, it is necessary to inspect and maintain each part of the injection molding machine at predetermined dates.
It is desirable that all the inspection items determined for each inspection date type be carried out each time the monthly inspection date or the annual inspection date arrives.

Therefore, in this embodiment, each periodic inspection date is set and stored in advance in the calculation control means 21.

When the calculation control means 21 recognizes that the regular inspection date has arrived by its own clock (timekeeping means) 29, the main control device of the calculation control means 21! 28 is.

No matter what display mode is selected, the CR
The T control device f130 is configured to prioritize and display the periodic inspection display mode screen corresponding to the type of inspection date. That is, the CRT control device 30 displays the periodic inspection display mode screen corresponding to the monthly inspection date, every 6 months inspection date, or the annual inspection date, according to the display program, display data code, etc. created in advance. On the display screen of the display device 23, characters and graphic patterns are displayed at predetermined positions and in predetermined colors.

In this embodiment, the injection molding machine is allowed to operate even if the periodic inspection display mode screen is displayed, but when the periodic inspection display mode screen is displayed, the machine operation is forcibly stopped and an inspection end signal is sent. Alternatively, the machine can be made inoperable until an inspection hold signal is input, which has the effect of prompting the operator to carry out inspection.

In addition, in this embodiment, the inspection dates are set so that the monthly inspection date, the 6-monthly inspection date, and the annual inspection date do not overlap on the same day, but these different types of regular inspections It is also possible to set the dates on the same day. In this case, you can set the priority order and display the periodic inspection display mode screen corresponding to the monthly inspection date, every 6 months inspection date, or the annual inspection date. It is sufficient to display them sequentially. At this time, a message such as ``Today corresponds to the monthly inspection date and every 6 monthly inspection date, so first, the periodic inspection items for the monthly inspection date will be displayed.'' By displaying a message such as, the operator can easily recognize that different inspection dates have arrived at the same time.

FIG. 2 is an explanatory diagram showing an example of a periodic inspection display mode screen displayed on the display screen 23a of the display device 23.
The figure shows a periodic inspection display mode screen corresponding to monthly inspection dates.

In FIG. 2, shown in the upper left is a mode selection display section 31, which is provided with a 1 inspection start display 31a, a pending display 31b, and 2 inspection end displays 31c. 32 is inspection item-
In the display section, the check item 8-' is displayed below the mode selection display area 31, and in the illustrated example, the check item 8-' is displayed in letters with a number added to the beginning of the sentence. 33 is the inspection item detailed explanation section displayed on the right side of the display screen, and the detailed explanation corresponding to one of the inspection items shown in the 1 inspection item-cut section 32 shows the part of the machine corresponding to the inspection item. This is indicated by a graphic pattern display 33a and a cautionary text display 33b. In addition, inspection item-list section 32
The "0" mark on the left side of each inspection item shown in the figure indicates an inspected mark 34, and the rXJ mark indicates an unfinished inspection mark 35.Now, the periodic inspection table corresponding to the monthly inspection date is shown. In the initial state when the Temode screen was displayed.

An inspection unfinished mark 35 is attached to each inspection item in the navigation inspection item list section 32. In this state, when the operator places the cursor on the position of the inspection start display 31a on the mode selection display m position 31 (or, with the cursor placed on the position), the operator checks the key manual device 22.
Press the run key or press key 2
2), the arithmetic and control means 21 recognizes this and stops the operation if the machine is in operation.

Next, when the operator operates the cursor movement key of the key-powered device 22 and places the cursor 36 on a desired inspection item in the inspection item list section 32 (or the cursor 36 is automatically moved to the first inspection item). ), the details corresponding to this inspection item are displayed in a graphic pattern display 33a and a cautionary text display 33b in the inspection item detailed explanation section 33.
displayed by. For example, if the cursor 36 is
．． When the item "Cleaning the suction strainer" is located, a graphic pattern display 33a and a cautionary text display 33b as shown in FIG. 2 are displayed, and the cursor 36 is
When the item "2. Inspection of band heater bolts and nuts" is selected, a graphic pattern display 33a indicating the position of the band heater, etc. and a related cautionary text display 33b are displayed. Therefore, even a novice operator can easily and reliably perform inspections by referring to the display in the 1-inspection-item detailed explanation section 33. Note that the display of the detailed inspection item explanation section 33 can be rewritten in any order by moving the cursor 36.

As described above, when the operator selects an inspection item in the inspection item list section 32 and finishes the inspection work for this inspection item by referring to the display in the inspection item detailed explanation section 33, the inspection item With the cursor 36 aligned, the operator presses a specific key (inspection completed mark input key) on the rhinoceros human-powered device 23, thereby changing the inspection unfinished mark 35 attached to the inspected item. The inspection completed mark 34 is rewritten and displayed. by this.

The operator displays screen 2 to check the inspection items that have been completed.
This can be done on 3a. In this way, the inspection items in the inspection item list section 32 are selected sequentially or in random order, and each time the inspection work for the selected inspection item is completed, the inspected mark 3 is displayed.
4 and all the inspection items in the inspection item list section 32 are marked with an inspected mark 34, the operator moves the cursor 3 to the inspection completion display 31c of the mode selection display section 31.
6 (or press the confirmation/execution key on the key manual device 22 with the cursor placed at this position, or press the inspection end key specially provided on the key manual device 22). As a result, the arithmetic control means 21 considers that the periodic inspection has been completed, erases the periodic inspection display mode screen, causes the display device 1123 to display the initial screen mode, and returns the machine to an operable state. However, when all inspection items are marked with the inspected mark 34, it is also possible for the arithmetic and control means 21 to automatically recognize that the periodic inspection has been completed.

In addition, if you want to postpone the inspection work to the next day or later due to the initial state when the periodic inspection display mode screen is displayed, or the one-hour restriction when one inspection task is completed for some inspection items, , the operator moves the cursor 36 to the position of the pending display 31b of the mode selection display section 31 (or the operator moves the cursor 36 to the position of the hold display 31b)
2, or by pressing an inspection hold key specially provided on the key-powered device 22), whereby the arithmetic control means 21 can be activated by 1, for example, the display device 23. The system displays the initial screen mode, recognizes that the inspection has not been completed on the originally set periodic inspection date, and stores this. Then, the arithmetic and control unit 21 displays the periodic inspection display mode screen with priority again from the next day onwards. Note that if some inspection items have been inspected the previous day (or the day the machine was last stopped), the inspected items will be marked with the inspection mark 34 as described above. Therefore, the operator only has to inspect the inspection items marked with the inspection incomplete mark 35 from the next day onwards.

As described above, by providing a selection mode for suspending inspection when the periodic inspection display mode screen is displayed, it is possible to flexibly delay the periodic inspection date without interfering with the production schedule. In addition, in the periodic inspection display mode screen that will be displayed again the next day, if some items are marked with the inspected mark 34, only the inspection items marked with the 2-inspection incomplete mark 35 will be inspected. Therefore, even if the operator changes, there is no risk of redundant inspection of items that have already been inspected.

In this embodiment, when the periodic inspection display mode screen is displayed, when the cursor 36 is placed on the inspection completion display 31c of the mode selection display section 31 (or the cursor 36 is placed on the inspection completion display 31c), the key manual device 22 is checked.・When you press the execution key or press the inspection completion instruction key specially installed on the key manual device 22)
, the calculation control means 21 determines that even if all of the inspection items are marked with the inspection unfinished mark 35, the periodic inspection has been completed (or the current periodic inspection is not required). I'm starting to look at it.

The reason why such a forced periodic inspection display mode screen clearing mode is provided is that some users, such as operators or site managers, perform periodic inspections at their own discretion, or due to completely unavoidable reasons. However, selection of such forced periodic inspection display mode screen clearing mode is performed by a key operation known only to a person in a responsible position. You can also do this.

FIG. 3 is an explanatory diagram showing another example of the periodic inspection display mode screen displayed on the display screen 23a of the display device 23. Mode screen is shown.

Here, the reference numerals in FIG. 3 indicate those corresponding to those in FIG. 3, and the details corresponding to this inspection item are displayed in the detailed inspection item explanation section 33 by a graphic pattern display 33a and a cautionary text display 33b. Furthermore, although not shown, the periodic inspection display mode screen corresponding to the annual inspection date is also displayed in a similar format.

As described above, in this embodiment, inspection items that match the periodic inspection date type are automatically displayed on the periodic inspection display mode screen, corresponding to periodic inspection days with different inspection interval dates and times. Therefore, the operator can easily and reliably inspect the inspection items that match the periodic inspection date type without referring to the instruction manual or manual.

FIG. 4 is a flowchart showing an example of the main processing flow of periodic inspection mode display executed by the arithmetic and control means 21.

In FIG. 4, Sl is a step for inquiring whether an instruction to suspend inspection as described above has been given, and if YES, jumps to step S4, and then returns to N.

If so, proceed to step S2. In step S2, a built-in timer determines whether or not the preset periodic inspection date falls; if YES, proceed to step S3;
If NO, the process ends. In step S3, it is determined whether the above-described inspection has been completed. If YES, the process ends; if NO, the process advances to step S4. Step S

A command to display a periodic inspection mode screen appropriate for the corresponding inspection date type is issued, and the display device 23 displays a display as shown in FIGS. 2 and 3, and the process proceeds to step S5. In step S5, a question is asked as to whether or not the above-mentioned inspection suspension instruction has been input this time. If YES, the process is completed after registration to suspend the inspection is made in step S6, and if NO, the process proceeds to step S7. In step S7, a question is asked as to whether or not an instruction to end the inspection has been given. If YES, the process ends; if NO, the process returns to step S4.

FIG. 5 is a flowchart showing an example of the rewriting processing flow of the inspection item detailed explanation section 33 executed by the arithmetic and control means 21 in the periodic inspection mode screen display state.

In FIG. 5, S11 is a step of determining whether or not the cursor Na has changed in the inspection item list section 32 (whether or not the position of the cursor 36 indicating the inspection item Nα has changed); if YES, Proceed to step S12, and
If o, jump to step S18. Step S12
Then, storage processing for the new cursor is performed, and the process advances to step 13.

In step S13, the detailed explanation display corresponding to the previous inspection item is deleted, and the process advances to step S14. In step S14, a search is made for the detailed explanation corresponding to the new stored cursor Nα, and the process proceeds to step S15. In step S15, the searched new detailed explanation is displayed.

Proceed to step 816. In step S16, a question is asked as to whether an instruction to suspend inspection as described above has been input.
If S, the process ends after registration to suspend the inspection is made in step S17, and if NO, the process advances to step S818. In step 818, a question is asked as to whether or not an input has been made indicating that the inspection of all inspection items has been completed (for example, whether or not the instruction signal for the completion of the inspection has arrived, or whether the inspection completed mark has been added to all the inspection items). ),
If YES, the process ends; if No, the process returns to step Sll.
Return to

By the way, in this embodiment, a calendar display mode is provided in which a list of regular inspection dates is displayed on the display w23 at any time.

This calendar display mode can be specified by, for example, instructing an option screen while the initial screen mode is displayed on the display screen 23a of the display device 23, and selecting and instructing the calendar display mode on this option screen. done by.

FIG. 6 is an explanatory diagram showing an example of a calendar display mode screen displayed on the display screen 23a of the 1 display device 23. In this embodiment, six months' worth of calendars are displayed simultaneously; for example, the 1st year indicator 37
With the cursor positioned at
The calendar for the first six months of the year is displayed. In addition, if there is no instruction for 1st year.

The calendar is automatically displayed for the next six months, including the current month.

In FIG. 6, the display for January to June 1989 is shown. Also, in the state shown in the sixth figure, if you press the "↑" key on the keypad 22 once, the calendar will be scrolled back by January (December 1988 to May 1989 will be displayed). ), and press the "↓" key once in the state shown in Figure 6, the calendar will be advanced by January and scroll displayed (February to July 1989 will be displayed). There is.

In the calendar display mode screen of FIG.

The monthly inspection dates, every 6 months inspection dates, and the annual inspection dates before the preset inspections are displayed in different colors, and 1 inspection date that has been completed and 1 inspection that has been put on hold. Inspection dates are also displayed in different colors. The reference for this color classification is determined in the explanation section 38. Therefore, by selecting this calendar display mode screen,
The operator can check at a glance when the next inspection date will arrive, can formulate a production plan that takes the inspection date and inspection time on that day into consideration, and can also prepare inspection tools in advance.

In addition, on the calendar display mode screen of FIG. 6, by placing the cursor 36 on the inspection schedule change display section 39 (or by placing the cursor 36 on this position and pressing the confirm/execute key), the calculation control means 21 enters an inspection date change mode, and for example, although not shown, a function key for date change operation and an explanation indicating the type of use thereof are displayed at an appropriate portion of the display screen 23a. After entering this inspection date change mode, by operating the function keys, cursor movement keys, numerical keys, etc. of the key manual device 22 as necessary, the periodic inspection scheduled date that you wish to change is set to the desired date. Change to Thereby, the arithmetic control means 21 erases the old inspection date and appropriately rewrites and retains the changed new periodic inspection date in the memory. When such a change operation is completed, the inspection date change mode is exited by an appropriate key operation, and thereafter, the calendar display mode is terminated by an appropriate key operation.

By making it possible to change the inspection date in this way, it is possible to create a reasonable periodic inspection implementation schedule that matches the production schedule.

FIG. 7 is a flowchart showing an example of the above-described calendar display processing flow executed by the calculation control means 21.

In FIG. 7, step 21 is a step in which it is asked whether or not the year has been specified; if YES, step 522
Displays the calendar for the first six months of the year specified in step S24, and if NO, step S323.
Then, a calendar for the next six months including the current month is displayed, and the process advances to step S24. In step S24, it is determined whether an operation to scroll the calendar forward or backward is performed using the above-mentioned "↑" key or "↓" key, and if No, the process jumps to step 826 and YES is selected.
If so, after scrolling the calendar specified in step S25, proceed to step S26, step S
In step S26, a question is asked as to whether or not the above-described inspection date change mode has been instructed, and if No, the process jumps to step S32, and Y
If ES, the image for the change operation described above is displayed in step S27, and then the process advances to step 828.

In step 828, it is determined whether the date of the first inspection has been changed, and if NO, the process jumps to step S31, and Y
If it is ES, the original periodic inspection date specified for change is deleted in step S29, and then a new inspection date is updated and registered in step S30.

Thereafter, the process advances to step S31. In step 531, it is determined whether a key indicating the end of the change operation has been pressed. If YES, the process advances to step S32; if NO, the process returns to step S27. In step S32, a question is asked as to whether or not a keystroke indicating an instruction to end the calendar display has been made. If YES, the series of processing ends; if NO, the process returns to step S24.

Although the present invention has been described above with reference to the illustrated embodiments, it goes without saying that various modifications can be made by those skilled in the art without departing from the spirit of the present invention.

For example, the inspection date interval (inspection date type) and the corresponding inspection items can be set arbitrarily. Further, the form for various input instructions is arbitrary, and in some cases, it is possible to use an appropriate input means such as a so-called mouse in addition to a key input device. Further, various modifications can be made to the processing flow executed by the arithmetic control means.

[Effects of the Invention] As described above, according to the injection molding machine according to the present invention, the arithmetic control means recognizes the arrival of the regular inspection date.

Since the periodic inspection display mode screen corresponding to the type of periodic inspection date is displayed with priority, it is possible to make the operator reliably aware of the necessity of inspection and to urge him or her to do so. Therefore, the conventional situation where regular inspections are neglected due to forgetting the inspection date can be avoided as much as possible, so machine troubles can be prevented and the life of the machine can be extended. In addition, the necessary inspection items are displayed according to the type of periodic inspection date, so operators can easily check which items to inspect and how, without having to refer to instruction manuals or manuals. This type of injection molding machine has a remarkable effect of being able to reliably recognize the extracted form.

In addition, by specifying the inspection item displayed on the periodic inspection display mode screen by moving the cursor on the display screen, the part corresponding to the specified inspection item will be displayed graphically and the notes will be displayed in text. Following this specific guidance, even novice operators can easily
It becomes possible to perform inspection work reliably.

In addition, when the periodic inspection display mode screen is displayed (on the periodic inspection date), for example, the inspection cannot be performed due to unavoidable circumstances related to production planning, or only a portion of the displayed inspection items can be inspected due to time constraints. If it is not possible to carry out the inspection, you can instruct the inspection to be suspended so that the periodic inspection display mode screen will be displayed again the next day or later.
It is possible to prompt operators to carry out periodic inspections that do not interfere with production schedules without forgetting inspection dates. In addition, when you perform inspection work for some of the displayed inspection items, if you mark the inspected items as completed, one inspection will be displayed on the periodic inspection display mode screen that will be displayed again from the next day onward. Since inspection can be prompted only for inspection items that are not marked as complete, there is no risk of duplicate inspections even if the operator changes from the previous day, for example.

Furthermore, since a calendar display mode is provided that shows the regular inspection dates in a list, by selecting this mode, it is possible to know in advance when the regular inspection date will arrive. In addition, in this calendar display mode, if an inspection cannot be performed on the scheduled periodic inspection date due to production planning requirements, vacation schedules, etc., the inspection date can be changed within the allowable period. Therefore, it is possible to create a reasonable periodic inspection schedule that matches the production schedule.
