Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an injection molding machine provided with a micro computer for integrally controlling the entire injection molding machine and a display device such as a CRT display. The present invention relates to an injection molding machine capable of automatically prompting execution on an initial inspection day.

[Prior art] Conventionally, an inspection of an injection molding machine is performed by an operator, a person in charge of handling, etc., by himself / herself detecting that the inspection date has been reached according to an inspection schedule or the like, and referring to an instruction manual, manual, or the like. In general, a method is used, and in some cases, a user performs an inspection only when a failure or abnormality occurs in a machine.

[Problems to be Solved by the Invention] As described above, conventionally, an operator or a work manager himself recognizes an inspection date on a schedule table, a calendar, or the like, and performs a periodic inspection. In many cases, regular inspection dates were ignored or forgotten. For this reason, problems have been pointed out, such as causing a machine trouble or shortening the life of the machine. In addition, it is relatively troublesome to perform an inspection while turning over the instruction manual and manuals while referring to the inspection items and the specific instructions related thereto, and if the instruction manuals and manuals are lost, the inspection items become unknown. There is also a problem that correct inspection cannot be performed. Furthermore, regular inspection dates (different types) with different inspection intervals, such as every month, every six months, and every year, are usually set for this type of injection molding machine. Of course, the inspection items will change if the type of the inspection is different. However, for operators who are not used to the equipment, what items should be inspected on a monthly inspection date, a six-month inspection date, and a yearly inspection date. There was also a problem that it was difficult to tell if it was enough.

The present invention has been made in view of the above points, and it is an object of the present invention to provide an injection molding machine in which an injection molding machine itself can prompt an operator to perform an inspection on an intended periodic inspection date. It is in. Further, another object of the present invention is to provide an injection molding machine capable of displaying an inspection item corresponding to the periodic inspection day type for each periodic inspection day of a different type, and instructing an operator to execute an accurate inspection. Is to provide.

Means for Solving the Problems In order to achieve the above object, the present invention provides an arithmetic processing means for controlling the entire injection molding machine, and a display device for displaying various modes by an output of the arithmetic processing means. And an input device, wherein the arithmetic processing means, when recognizing the arrival of the periodic inspection date by the built-in clock, automatically displays a periodic inspection display mode screen corresponding to the identification of the arrived periodic inspection date. In an injection molding machine that prompts an operator to perform an inspection, for each inspection item displayed on the periodic inspection display mode screen, the operator can assign an inspected mark indicating that an inspection operation has been performed, When all or some of the displayed inspection items are not to be inspected when the periodic inspection display mode screen is displayed, On and after the next day, the periodic inspection display mode screen is displayed again, and the inspection item that has already been given the inspection mark at the time when the inspection hold is instructed is given the inspection mark even at the time of redisplay. It is configured to display.

[Operation] As described above, when the arithmetic processing means including, for example, a micro computer of the injection molding machine itself recognizes the arrival of the periodic inspection date by a built-in clock (clocking means), the type of the arrived periodic inspection day is determined. For example, if the inspection date is every month, this is met. 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, and to avoid a situation in which the inspection time is missed due to forgetting the inspection date or the like as much as possible. In addition, since necessary inspection items are displayed in accordance with the type of the periodic inspection date, the operator can reliably recognize which item should be inspected.

Also, by designating the inspection items displayed on the periodic inspection display mode screen by a cursor moving operation on the display screen, a graphic display of a portion corresponding to the designated inspection item and a character display of notes are made, According to this specific guidance, even a novice operator can easily and reliably perform the inspection work.

Also, when the periodic inspection display mode screen is displayed (on the date of the periodic inspection), for example, inspection cannot be performed due to unavoidable circumstances in the production plan, or only a part of the displayed inspection items is inspected due to time constraints. If it is not possible to implement
By instructing the suspension of the inspection, the periodic inspection display mode screen is displayed again from the next day.
Therefore, it is possible to prompt the operator to perform a periodic inspection that does not hinder the production schedule without forgetting the inspection date. In addition, when a part of the displayed inspection items is inspected, the inspected items are marked with an inspected mark. The user is prompted to check the check items that are not marked. As a result, even if the operator is different from the previous day, there is no possibility that the inspection is repeatedly performed.

Furthermore, by selecting a calendar display mode that shows a list of the periodic inspection dates, it is possible to recognize in advance when the periodic inspection dates have arrived. In the calendar display mode, if the inspection cannot be carried out on the scheduled periodic inspection date, for example, due to a request on a production plan or a vacation schedule, the inspection date is changed within an allowable period. Is made possible.

[Embodiment] Hereinafter, the present invention will be described with reference to one embodiment shown in FIGS.

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

In FIG. 1, reference numeral 1 denotes a base, and a plurality of tie bars 4 are disposed between a fixed die plate 2 and a support board 3 installed on the base 1, and the tie bar 4 is slidably movable.

The movable die plate 5 is moved by the forward and backward movement of the piston rod 6a. It moves forward or backward with respect to the fixed die plate 2. In addition, 8 is a fixed side mold attached to the fixed die plate 2, and 9 is a movable side mold attached to the movable die plate 5.

Reference numeral 10 denotes a heating cylinder, 11 denotes a screw screw that is rotatable in the heating cylinder 10 and can move forward and backward, 12 denotes a hopper for supplying a resin material, 13 denotes a motor for driving the screw 11 to rotate, and 14 denotes a motor. This is an injection cylinder that controls the forward and backward movement of the screw 11.

As is known, the hopper 12 and the screw 11
The resin material supplied to the rear end is kneaded and plasticized by the rotation of the screw 11 and is transferred forward while being kneaded and plasticized. Retreats while controlling the back pressure, and the rotation of the screw 11 is stopped when the molten resin stored at the tip end side of the screw 11 reaches the amount of one shot. Then, the screw 11 is driven forward at an injection start timing after a lapse of a predetermined time, and the molten resin is injected into the cavity formed by the molds 8 and 9 whose molds are closed (clamped). The pressure is maintained for a predetermined second. Thereafter, the mold is opened in a state where the resin injected into the mold is cooled and solidified, and the product (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 a product attached to the mold, 20 is an unloader operation detection sensor attached to the unloader 15, and Measurement information from the sensors 16 to 20 and other sensors (not shown) is transmitted to an arithmetic and control unit described later via an input conversion circuit as needed.

Reference numeral 21 denotes an arithmetic control unit mainly composed of a micro computer that controls the entire injection molding machine, 22 denotes a key input device for inputting various commands to the arithmetic control unit 21, and 23 denotes a processing result by the arithmetic control unit 21 and the like. A display device, such as a color CRT display, for displaying a display pattern or the like created in advance, 24 is a printer for printing out the processing results and the like by the arithmetic control means 21, and 25 is an arithmetic control means 21
And an external storage device for exchanging data as needed.

The arithmetic and control unit 21 includes an input / output interface 26,
It has an input / output conversion operation device 27, a main control device 28 with a built-in clock 29, a CRT control device 30, etc., for controlling the automatic operation of the injection molding machine and displaying various display mode screens on the display device 23. It is displayed. Here, the arithmetic control means 21 is mainly composed of a microcomputer as described above, and in fact, a ROM storing various I / O interfaces, a main program, fixed data, etc., measurement data, A RAM for reading and writing various flags and the like, a clock, an MPU for controlling the overall control, and the like are provided, and the clock and main memory are backed up by batteries. Then, the arithmetic control means 21 controls the automatic operation of the injection molding machine based on various programs created in advance, and causes the display device 23 to display a screen of various display modes.

That is, the arithmetic control unit 21 refers to the output from each sensor based on the molding sequence control program created in advance and the set condition value, for example,
The opening / ejection / product removal process, the mold closing / tightening process, the injection / pressure-holding process, the charging process, etc. are controlled and executed. Controls the drive source of each part of the injection molding machine.

The arithmetic control means 21 displays various periodic inspection display mode screens, various condition setting mode screens, operating condition monitoring mode screens, etc., based on a command from the key input means 22 or the judgment of the arithmetic control means 21 itself. It is like that.

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 every predetermined date, and this periodic inspection is performed, for example, on a monthly inspection day,
It is desired that every six days of the inspection day and one year of the inspection day arrive at all the inspection items determined for each inspection day type. Therefore, in the present embodiment, each of the periodic inspection dates is set and stored in advance in the arithmetic control means 21, and the arithmetic control means 21 reaches the periodic inspection date by its own clock (time measuring means) 29. When the main control device 28 of the arithmetic and control unit 21 recognizes, the CRT control device 30 gives priority to the periodic inspection display mode screen corresponding to the type of the inspection date, regardless of the display mode selected. Display. That is, the CRT controller 3
0 indicates a periodic inspection display mode screen corresponding to a monthly inspection date, a six-month inspection date, or a yearly inspection date according to a display program, a display data code, or the like created in advance. On the display screen, characters and graphic patterns are displayed at predetermined positions in predetermined colors.

In the present embodiment, the operation of the injection molding machine is enabled even when the periodic inspection display mode screen is displayed. However, when the periodic inspection display mode screen is displayed, the machine operation is forcibly stopped, and the inspection end signal is displayed. Alternatively, it is possible to disable the operation of the machine until the inspection hold signal is input, so that the operator can be further urged to execute the inspection.

In this embodiment, the inspection dates are set so that the monthly inspection date, the six month inspection date, and the yearly inspection date do not overlap on the same day. It is also possible to set the date on the same day. In this case, the priority order is determined, and the periodic inspection display mode screen corresponding to the monthly inspection date, the six-month inspection date, or the annual inspection date is set. What is necessary is just to make it display sequentially. At this time, on the display screen, for example, “Today corresponds to the monthly inspection date and the sixth monthly inspection date, so the periodic inspection items for the monthly inspection date are displayed first.” If you display a message such as
The operator can easily recognize that different types of inspection dates have arrived at the same time.

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

In FIG. 2, the upper left portion is a mode selection display portion 31, which is provided with an inspection start display 31a, a hold display 31b, and an inspection end display 31c. Reference numeral 32 denotes an inspection item list section, which is displayed below the mode selection display portion 31. In the example shown in the figure, eight inspection items are displayed with letters at the beginning of each sentence. Reference numeral 33 denotes an inspection item detailed explanation portion displayed on the right side of the display screen. Details corresponding to one of the inspection items shown in the inspection item list portion 32 are figures showing the parts of the machine corresponding to the inspection item. This is shown by a pattern display 33a and a precautionary character display 33b. In addition, the mark “○” on the left side of each check item shown in the check item list section 32 indicates the checked mark 34, and the mark “x” indicates the not-yet-checked mark 35.

Now, in the initial state in which the periodic inspection display mode screen corresponding to the monthly inspection day is displayed, all the inspection items in the inspection item list section 32 are all marked with an uncompleted inspection mark 35. I have. In this state, when the operator positions the cursor at the position of the inspection start display 31a of the mode selection display portion 31 (or pushes the confirmation / execute key of the key input device 22 with the cursor positioned, or When the inspection start key specially provided on the key input device 22 is pushed), the arithmetic control means 21 recognizes this and stops the operation when the machine is in the operating state.

Next, when the operator operates the cursor movement key of the key input device 22 to move the cursor 36 to a desired inspection item in the inspection item list section 32 (or the cursor 36 is automatically moved to the first inspection item). Then, details corresponding to the inspection item are displayed in the inspection item detailed explanation section 33 by a graphic pattern display 33a and a precautionary character display 33b. For example, when the cursor 36 is located at the position of the item "1. Cleaning the Suction Strainer", a graphic pattern display 33a and a note character display 33b as shown in FIG. When the item is matched with the item of "2. Inspection of band heater bolt nut", a graphic pattern display 33a showing the position of the band heater and the like and a notice character display 33b related thereto are displayed. Therefore, even a novice operator can easily and reliably perform the inspection with reference to the display of the inspection item detailed explanation section 33. The display of the inspection item detailed explanation section 33 can be rewritten by moving the cursor 36 in any order.

As described above, when the operator selects one of the inspection items in the inspection item list unit 32 and refers to the display of the inspection item detailed explanation unit 33, and ends the inspection work related to this inspection item,
With the cursor 36 positioned on the inspected item, the operator pushes a specific key (key for inputting an inspected mark) of the key input device 23, whereby the work item attached to the inspected item is checked. The inspection non-completion mark 35 is rewritten and displayed as the inspection completed mark 34. As a result, the operator can check the checked inspection items on the display screen 23a. In this way, one of the inspection items in the inspection item list section 32 is selected one by one sequentially or in random order, and each time the inspection work of the selected inspection item is completed, the inspection completed mark 34 is attached, and the entire inspection of the inspection item list section 32 is performed. When the inspected mark 34 is attached to the item, the operator displays the inspection end display of the mode selection display portion 31.
Move the cursor 36 to the position 31c (or push the confirmation / execute key of the key input device 22 with the cursor positioned at this position, or press the inspection end key specially provided for the key input device 22). To do). As a result, the arithmetic and control unit 21 considers that the periodic inspection has been completed, erases the periodic inspection display mode screen, for example, displays the initial screen mode on the display device 23, and sets the machine in the operable state. Place. When the inspection mark 34 is attached to all inspection items, the arithmetic control means 21
Can automatically recognize that the periodic inspection has been completed.

In addition, when the periodic inspection display mode screen is displayed in the initial state, or when the inspection work has been completed for some inspection items, if you want to postpone the inspection work to the next day or later due to time restrictions, etc. The operator is caused to position the cursor 36 at the position of the hold display 31b of the mode selection display portion 31 (or to confirm the key input device 22 with the cursor 36 positioned at this position).
The execution key is pushed, or the inspection hold key specially provided to the key input device 22 is pushed). As a result, the arithmetic and control unit 21 causes the display device 23 to display the initial screen mode, and recognizes that the inspection has not been completed on the initially set periodic inspection date, and stores it. Then, the arithmetic and control unit 21 causes the periodic inspection display mode screen to be preferentially displayed again after the next day. If the inspection work of some inspection items has been performed on the previous day (or the last day when the machine was stopped), the inspection completed items are marked with the inspection mark 34 as described above. Therefore, the operator only needs to execute the inspection of the inspection items to which the inspection non-completion mark 35 is attached on the next day or later.

As described above, when the periodic inspection display mode screen is displayed, the selection mode for suspending the inspection is provided, so that the flexible periodic inspection date can be delayed so as not to hinder the production schedule. . Also, on the periodic inspection display mode screen that is displayed again after the next day, if some items are marked with the inspection completed mark 34, only the inspection items with the inspection not completed mark 35 are inspected. Therefore, even if the operator changes, there is no possibility that the items that have already been inspected are inspected redundantly.

In the present embodiment, if the cursor 36 is positioned on the inspection end display 31c of the mode selection display portion 31 in the state where the periodic inspection display mode screen is displayed (or the cursor 36 is positioned to check the key input device 22). When the execution key is pushed or the inspection end instruction key specially provided on the key input device 22 is pushed), the arithmetic control means 21 sets the inspection non-completion mark 35 on all the inspection items, for example.
Even in the state marked with, it is assumed that the periodic inspection has been completed (or that the current periodic inspection is unnecessary). The reason why the forced periodic inspection display mode is provided with such a mode for deleting the screen is that, depending on the user, the operator or the site manager performs the periodic inspection at his / her own discretion, or is unavoidable at all. Although it is provided in consideration of the case where the inspection cannot be performed in such a case, the selection of such a forced erasure mode of the periodic inspection display mode screen is performed by a key operation known only to a responsible person. It may be executed.

FIG. 3 is an explanatory view showing another example of the 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 an inspection day every six months. Here, the reference numerals in FIG. 3 correspond to those in FIG. 2. In FIG. 3, the cursor 36 is positioned at the inspection item of “2. Toggle part grease up” in the inspection item list section 32. Further, a state is shown in which the details corresponding to the inspection item are displayed in the inspection item detailed explanation section 33 by the graphic pattern display 33a and the note text display 33b. Although not shown, 1
The periodic inspection display mode screen corresponding to the annual inspection date is also displayed in a similar form.

As described above, in the present embodiment, the inspection items found in the periodic inspection date type are automatically displayed on the periodic inspection display mode screen corresponding to the periodic inspection dates with different inspection interval dates and times. Therefore, the operator can easily and surely inspect the inspection items found for the regular inspection date type without referring to the instruction manual or manual.

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

In FIG. 4, S1 is a step for inquiring whether or not the above-mentioned instruction to suspend inspection has been issued. If YES, the process jumps to step S4, and if NO, the process proceeds to step S2. In step S2, it is determined by a built-in clock means whether or not the date corresponds to a preset periodic inspection date. If YES, the process proceeds to step S3, and if NO, the process ends. In step S3, it is determined whether the inspection described above has been completed, and
If YES, the process ends; if NO, the process proceeds to step S4. In step S4, a display command of the periodic inspection mode screen corresponding to the corresponding inspection date type is issued, the display as shown in FIGS. 2 and 3 is made by the display device 23, and the process proceeds to step S5. In step S5, it is determined whether or not the above-described instruction for suspending the inspection has been input this time. If YES, registration is made to suspend the inspection in step S6, then the process ends, and if NO, the process proceeds to step S7. In step S7, it is determined whether or not an instruction to end the inspection has been issued. If YES, the process ends, and if NO, the process returns to step S4.

FIG. 5 is a detailed explanation part of the inspection item executed by the arithmetic and control unit 21 in a display state of the periodic inspection mode screen.
FIG. 33 is a flowchart showing an example of a flow of a rewriting process of No. 33.

In FIG. 5, S11 is a step for judging whether or not the cursor No. has changed in the check item list section 32 (whether or not the position of the cursor 36 indicating the check item No. has changed). If yes, go to step S12, if no, step
Jump to S18. New cursor at step S12
No. is stored and the process proceeds to step 13. Step S
In 13, the detailed explanation display corresponding to the previous inspection item is deleted, and the process proceeds to step S14. In step S14, a search for a detailed description corresponding to the stored new cursor No. is performed, and the flow advances to step S15. In step 15, the new detailed description searched is displayed, and the flow advances to step S16. In step S16, it is determined whether or not the above-described instruction to suspend the inspection has been input. If YES, step S16 is executed.
After the registration indicating that the inspection is to be suspended at 17 is made, the process ends, and if NO, the process proceeds to step S18. In step S18, it is determined whether or not an input indicating that the inspection of all the inspection items has been completed has been made (for example, whether or not an instruction signal for ending the inspection has arrived, or the inspection completed mark is attached to all the inspection items). If YES, the process is terminated, and if NO, the process returns to step S11.

By the way, in the present embodiment, a calendar display mode is provided in which the periodic inspection dates are listed at any time and displayed on the display device 23. This calendar display mode is specified, for example, by giving an option screen instruction in a state where 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. Made by

FIG. 6 is an explanatory diagram showing an example of a calendar display mode screen displayed on the display screen 23a of the display device 23.
In this embodiment, a calendar for six months is displayed at the same time. For example, when the cursor is positioned on the date indicating section 37, a desired date is displayed by using the numerical keys of the key input device 22. , A calendar for the first six months of the age is displayed. If there is no indication of the age, calendars for the next six months including the current month are automatically displayed.

FIG. 6 shows a state in which the display for January to June 1989 is made. In the state shown in FIG. 6, when the "@" key of the key input device 22 is pushed once, the calendar is scrolled backward by one month (from December 1988 to May 1989 is displayed). When the "@" key is pushed once in the state shown in FIG. 6, the calendar is advanced by one month and scrolled (1989).
(February to July are displayed).

In the calendar display mode screen shown in FIG. 6, the predetermined inspection date, the inspection date every six months, the inspection date every six months, and the inspection date every year before performing the inspection are displayed in different colors, respectively. The completed inspection date and the inspection date on which the inspection is suspended are also displayed in different colors. The reference for this color classification is made in the color classification explanation section 38. Therefore, by selecting this calendar display mode screen, the operator can see at a glance when the next inspection date will come, and can make a production plan taking into account the inspection time of the inspection date. Also, inspection tools can be prepared in advance.

In the calendar display mode screen shown in FIG. 6, the cursor 36 is moved to the inspection schedule change display section 39 (or the cursor 36 is moved to this position and the confirmation / execute key is pushed), whereby the arithmetic control means is turned on. Reference numeral 21 denotes an inspection date change mode, in which, for example, although not shown, a function key for date change operation and a description indicating its use type are displayed on an appropriate portion of the display screen 23a. And after this inspection date change mode,
By operating the function key of the key input device 22, the cursor movement key, the numeric key, and the like as necessary, the scheduled scheduled inspection date to be changed is changed to a desired date. As a result, the arithmetic and control unit 21 erases the old inspection date and rewrites and holds the changed new periodic inspection date in the memory as appropriate. When such a change operation is completed, the operation is changed from the inspection date change mode by a key operation as appropriate, and thereafter, the calendar display mode is ended by an appropriate key operation.

By enabling the setting of the change of the inspection date in this way, it is possible to formulate a schedule for performing a reasonable periodic inspection according to the production schedule.

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

In FIG. 7, step 21 is a step for asking whether or not the age has been designated. If YES, a calendar display for the first six months of the age designated in step S22 is performed, and the process proceeds to step S24. Then, in step S23, a calendar display for the next six months including the current month is performed, and step S2 is performed.
Proceed to 4. In step S24, it is determined whether or not a scroll instruction operation for moving back and forth of the calendar has been performed by the above-mentioned "↑" key or "↓" key. If NO, the process jumps to step S26, and if YES, the process proceeds to step S25. After scrolling the calendar, step S26
Proceed to. In step S26, it is asked whether the above-described inspection date change mode has been instructed. If NO, the process jumps to step S32. If YES, the image for the change operation described above is displayed in step S27, and then to step S28. move on.

In step S28, it is determined whether or not the date of the inspection date has been changed.If NO, the process jumps to step S31, and if YES, the date of the original periodic inspection date designated to be changed in step S29 is deleted. The new inspection date is updated and registered in step S30, and thereafter, the process proceeds to step S31. In step S31, it is determined whether or not a key input indicating the end of the change operation has been made. If YES, the process proceeds to step S32, and if NO, the process returns to step S27. In step S32, it is determined whether or not a key input indicating an instruction to end the calendar display has been made.
If it is, the series of processing ends, and if NO, the process returns to step S24.

The present invention has been described with reference to the illustrated embodiment.
Needless to say, 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 (type of inspection date) and the setting of the inspection items corresponding thereto are arbitrary. Further, the form for various input instructions is also arbitrary. In some cases, other than the key input device, an appropriate input means such as a mouse may be used. Also,
The processing flow executed by the arithmetic and control unit can be variously modified.

[Effects of the Invention] As described above, according to the injection molding machine of the present invention, the arithmetic and control unit recognizes the arrival of the periodic inspection date and displays the periodic inspection display mode screen corresponding to the type of the periodic inspection date. Since the priority display is performed, it is possible to make the operator surely recognize the necessity of the inspection and to prompt the operator to do so. Therefore, it is possible to avoid a situation in which the regular inspection is neglected, for example, by forgetting the inspection date as in the related art, so that a machine trouble can be prevented and the life of the machine can be prolonged. In addition, necessary inspection items are displayed according to the type of periodic inspection date, so the operator can determine which items should be inspected and how to inspect them without having to refer to the instruction manual or manual. In this kind of injection molding machine, a remarkable effect can be obtained in that it can be surely recognized in the extracted form.

In addition, by specifying the inspection items displayed on the periodic inspection display mode screen because the cursor is moved on the display screen, a graphic display of a portion corresponding to the specified inspection item and a character display of precautions are made, According to this specific guidance, even a novice operator can easily and surely perform the inspection work.

Also, when the periodic inspection display mode screen is displayed (on the date of the periodic inspection), for example, inspection cannot be performed due to unavoidable circumstances in the production plan, or only a part of the displayed inspection items is inspected due to time constraints. If it is not possible to implement
By instructing the suspension of the inspection, the periodic inspection display mode screen can be displayed again after the next day, so that the periodic inspection that does not hinder the production schedule can be performed without forgetting the inspection date. It can prompt the operator. In addition, when a part of the displayed inspection items is checked, if the checked items are marked with an inspection mark, the inspection will be displayed on the periodic inspection display mode screen that is displayed again after the next day. Since it is possible to urge the user to inspect only the inspection items to which the done mark is not attached, even if the operator changes from the previous day, there is no possibility that the inspection will be repeatedly performed.

Furthermore, since a calendar display mode for listing the regular inspection dates is provided, by selecting this mode, it is possible to recognize in advance when the regular inspection dates will come. In the calendar display mode, if the inspection cannot be carried out on the scheduled periodic inspection date, for example, due to a request on a production plan or a vacation schedule, the inspection date is changed within an allowable period. Is possible, it is possible to plan a reasonable schedule for the regular inspection according to the production schedule.
