A manual data input device 29 with a display, which constitutes a part of the calendar display means for process control, is connected to the bus 22 via a CRT display circuit 26 to select a monitor display screen or a function menu and input various data. Etc., and a numeric keypad for inputting numerical data and various function keys are provided.

2 to 8 show a calendar for a predetermined period, registration of process control data corresponding to each month and day of the calendar, and
It is a flow chart showing an outline of the processing required to display the correspondence between the calendar and the process control data on a monthly basis. Hereinafter, referring to these flow charts, the process control calendar registration in the present embodiment will be described. Describe the function.

The PMC CPU 18, which has detected that the function menu for process control has been selected by operating the function keys of the manual data input device 29 with a display,
After changing the function key assignment of the manual data input device with display 29 to the state shown in FIG. 11, first, the calendar creation completion flag data is stored in the non-volatile memory 24.
Is set (step S)
1). The calendar creation completion flag data is a flag that is set when the calendar date data is set in the calendar storage means composed of the records of the first and second columns in the file means of FIG. Calendar creation completion flag data at the stage
If is not set, it means that the calendar is not set.

Therefore, when the calendar creation completion flag data is not set, the PMC CPU 18 first displays on the display screen of the manual data input device 29 with a display "from what year and from what year do you want to create a calendar?" Is displayed (step S4), and a standby state is awaited for the operator to input the ten-key pad for the start date of creation (step S5). Then, when the operator operates the ten-key pad of the manual data input device 29 with a display, which is a command means of the creation start month, and inputs the creation start date, the PMC CPU 18 detects this in the determination processing of step S5,
After the value of the creation start date is stored in the creation start date storage register yd of the nonvolatile memory 24 (step S6), RA
M14 month deviation storage register y, address counter q,
Initially set 0, 1, 1 to each of the date storage registers d (step S7), obtain the value dmax. Of the final date of the creation start year yd month based on the value of the creation start year yyd, and temporarily store it. (Step S8). It should be noted that the value of the final date of each month of each year is preliminarily written in the ROM 13 for the required number of months of the year in consideration of the expected shipping date of the injection molding machine, the useful life, and the like.

Next, the PMC CPU 18 determines whether or not the current value of the address counter q exceeds the value of the final address r in the file means of FIG. 14, that is, whether or not it exceeds the number of records that can be stored. (Step S9), but if it does not exceed (1 column, q
(Line) The current value of the month deviation storage register y, that is, the value y of the number of elapsed months counted with the creation start year as month 0 is stored in the spot record (step S10), and (2 columns,
(Line q) The current value of the date storage register d is stored in the spot record to create a calendar for one day (step S1).
1). Then, the PMC CPU 18 increments the values of the date storage register d and the address counter q (step S12), and determines whether the current value of the date storage register d exceeds the final date value dmax. If the current value of the date storage register d exceeds the value dmax. Of the final date of the current month, or if the current value of the address counter q is the value of the final address r in the file means (step S13). Until it exceeds, the same processing as described above is repeatedly executed.

While the above processing is repeatedly executed, the current value of the date storage register d is the value dmax.
When it exceeds, the PMC CPU 18 detects this in the determination processing of step S13 and resets the value of the date storage register d to the initial value 1 at the beginning of the month (step S14).
The value of the month deviation storage register y is incremented (step S15), and the creation start year / month yd and the month deviation storage register y are incremented.
The value of the final date of the new month is obtained in the same manner as above based on the added value of and the value of dmax. Is updated (step S1).
6). Then, the same processing as described above is repeatedly executed again, and the calendars on the day y month d with the creation start year yy as the month 0 are recorded in the records in the first and second columns of the file shown in FIG. Create minutes.

While the above processing is repeated, the current value of the address counter q exceeds the value of the final address r in the file means, and the creation start date yd is set to 0 for all the first to rth addresses of the file. When the calendar of y month d as a month is stored, the PMC CPU 18 initializes 0 in the display month storage register ya of the non-volatile memory 24 (step S17) and sets the calendar creation completion flag data (step S17). S18). That is, the calendar creating means in this embodiment is the processing from step S5 to step S16, and the first column and the second row in the file means in FIG.
The calendar storage means constituted by the records in the column stores calendars for a predetermined number r of days including the first day of the year yd.

When an automatic maintenance date setting command, which is a type of production control data forming the process control data, is input by a key operation of the manual data input device 29 with a display, the PMC CPU 18 detects it. (Step S19), manual data input device 29 with display
A guidance message such as "Please enter the date and interval of the first day to perform maintenance work in days" is displayed on the display screen of (step S20), and the operator can confirm the date and the interval of the first day. A standby state waiting for numeric key input is entered (step S21). Then, when the operator operates the ten keys of the manual data input device 29 with a display to input the date of the first day and the number of days interval, P
The MC CPU 18 detects this in the determination processing of step S21, temporarily stores the number of days interval in the register k, and initializes the date of the first day in the address counter q (steps S22 and S23). Below, CPU18 for PMC
Until the current value of the address counter q exceeds the value of the final address r in the file means (step S2
4), the numerical value 1 corresponding to the display data of the maintenance date in the maintenance management item storage record of the spot (4th column, qth row) of the file shown in FIG. 14 in increments of the number of days interval k (see table F2 in FIG. 13). Are set (steps S25 and S26). When the current value of the address counter q exceeds the value of the final address r in the file means and the automatic maintenance date automatic setting process for the entire calendar period is completed, the process proceeds to the next process (step S24). If the maintenance date automatic setting command is not input, step S20 is performed.
The process of step S26 is canceled, and the maintenance date is set by performing a manual setting operation described later as necessary.

Next, the PMC CPU 18 determines the first based on the creation start year / month yd and the added value of the display month storage register ya and the value dmax. Of the final date corresponding to the year / month of the added value.
After reading the calendar for a month from the file and displaying it on the display screen of the manual data input device 29 with a display as shown in FIG. 11, the cursor designation index x is initialized to 1 and the position of x days on the display screen. The cursor is displayed at (step S27). "1" in FIG.
“993” and “12” are values obtained by dividing the added value of the creation start year / month yd and the display month storage register ya into years and months. Of course, each year when the month value exceeds 12, the year value is incremented. The month value is reset to 1. At this stage, the production control item storage record in the third column in the file,
If a numerical value other than 0 is stored in the maintenance management item storage record in the fourth column and the work management item storage record in the fifth column,
The display data corresponding to the numerical values of the production management items, maintenance management items, and work management items stored at the addresses of the files corresponding to the dates of the sections displayed on the display screen are the table F1 of the ROM 13 as shown in FIG. ~ F3
Although it is displayed with reference to, the data of the third column, the fourth column, and the fifth column of the file are all initialized to 0 immediately after the new calendar is created, so the data of various management items Do not show. However, when the above-described automatic maintenance date setting process is executed, since the data 1 has already been set in the maintenance management item storage record in the fourth column at the predetermined number of days interval k, the data number 1 in the table F2 is set. The display data “maintenance date” corresponding to is displayed corresponding to the date. Although not displayed here, it goes without saying that the display data of the table F1 is displayed according to the numerical value of the production management item storage record in the third column, and the display data of the table F3 is displayed according to the numerical value of the work management item storage record in the fifth column. It is.

Next, the PMC CPU 18 initializes the values of the monthly deviation integration counter i and the total days integration counter ds of the non-volatile memory 24 to 0 (step S28), and the value of the counter i is calculated from the value of the display month storage register ya. Is also small (step S29). The total number of days integration counter ds is a counter indicating the address of the file corresponding to the date immediately before the first date of the month currently displayed on the display screen of the manual data input device with display 29, and the cursor is set on the value of the counter ds. Designated index x
Is added, that is, the record of the address corresponding to the date designated by the cursor in the display of the year / month portion currently displayed on the display screen of the manual data input device with display 29 is production controlled. Items, maintenance management items, and work management items are set. Immediately after the new calendar is created, ya = 0 (see step S17),
Since i = 0, the determination result of step S29 becomes false, the processing of steps S30 and S31 is canceled, and the value of the total number of days integration counter ds is held at the initial value 0. Therefore, before operating the cursor movement key. At the present time, ds + x = 1, and whether or not the first day of the yy-year indicated by the cursor position, that is, the record of the first address in the file of FIG. 11 starts the data setting operation for the process control as it is. Separately, it means that the items are set as production management items, maintenance management items, and work management items. In the state where the calendar of yd year, which is the creation start month, is displayed, d is displayed in the value of the cursor designation index x.
A value obtained by adding s = 0, that is, the date itself indicated by the value of the cursor designation index x coincides with the address of the file means.

The PMC CPU 18, which has completed the creation of the calendar for r days from the creation start year yd by the above processing, moves to the processing of step S3 and operates the newly created key for resetting the calendar. (Step S3), operation of the next month key for displaying the calendar one month ahead of the displayed year and month (step S32), to display the calendar one month before the displayed year and month Operation of the previous month key (step S36), operation of the cursor movement key for specifying the date for setting the process control data (step S40), and the table F1 of FIG. 13 for the date specified by the cursor. Operation of the production control key for selecting and setting display data of the production control item from step (step S42), display of the maintenance control item from the table F2 of FIG. 13 for the date designated by the cursor Operation of the maintenance management key for selecting and setting the data (step S48), for selecting and setting the display data of the work management item from the table F3 in FIG. 13 for the date designated by the cursor. A standby state is waited for either the operation of the work schedule key (step S54) or the operation of the end key for ending or interrupting the setting action (step S60).

It should be noted that once the above-described process relating to calendar creation is completed, the end key can be operated and the power can be turned off at any time. For example, when the above-mentioned process related to calendar creation is completed, the end key is operated without performing any setting operation to end the process management function menu,
Even if this function menu is selected again, the calendar creation completion flag data, the creation start year / month storage register yd, and the display month storage register ya are all non-volatile registers.
After selecting the function menu and executing the determination processing in step S1, the above-described step S is performed based on the values in these registers.
The process of step S2 is first executed in exactly the same way as the process of 27, and the calendar for one month displayed immediately before the operation of the end key or the power-off is displayed as shown in FIG. It is displayed on the display screen of the device 29 in exactly the same manner as before, and the cursor is displayed at the position of the first day. In this case, the processing of steps S28 to S31 required for associating the value of the total day number integration counter ds with the address of the date immediately before the first date of the displayed month is not executed, but the display data itself is changed. Moreover, since the value of the total day integration counter ds is already stored in the nonvolatile memory, there is no problem. Immediately after the display process of step S2, the cursor movement operation for setting the process control data for the displayed month is performed. You can get started. If the input operation of the creation start month yd is incorrect, the newly created key is operated again to execute the same process as described above to create a desired calendar.

Therefore, after the creation of the calendar, the operator
First, a month for which process control data is set is selected by operating the next month key or the previous month key, which is a display month designating means, and the calendar for the one month is displayed on the display screen of the manual data input device 29 with a display. Will be made. If the calendar first displayed on the display screen of the manual data input device with display 29 is the target month for setting the process control data, the next month key and the previous month key need not be operated.

If the next month key is operated, step S
3, step S32, step S36, step S4
0, step S42, step S48, step S5
4, PM that repeatedly executes the determination process of step S60
The C CPU 18 detects this operation in the determination processing of step S32 and increments the value of the display month storage register ya (step S33), and the current value of the display month storage register ya is the file (1st column, r row). It is determined whether or not the maximum monthly deviation A (1, r) stored in the spot record is exceeded (step S34). If the current value of the display month storage register ya exceeds the maximum value A (1, r) of the month deviation, yd + ya> yd + A (1, r), and yd
Since it means that the calendar corresponding to the year and month of + ya is not set in the file, naturally the calendar of this month cannot be displayed. Therefore, in this case, C for PMC
The PU 18 resets the value of the display month storage register ya to 0 in order to cyclically display the created calendar of the first month (step S35), and shifts to the next process. On the other hand, if the current value of the display month storage register ya does not exceed the maximum value A (1, r) of the month deviation, the calendar of yd + ya year / month can be displayed.
The process of 35 is not executed, and the process proceeds to the next process.

When the previous month key is operated, the PMC
The CPU 18 for detection detects this operation in the determination processing of step S36 and decrements the value of the display month storage register ya (step S37) to check whether the current value of the display month storage register ya is smaller than 0 or not. It is determined (step S38). If the current value of the display month storage register ya is smaller than 0, then yd + ya <yd, which means that the calendar before the creation start year yy is displayed.
Naturally, such a thing is impossible, so CP for PMC
U18 sets the value of the display month storage register ya to A (1,
r) is reset (step S39), and the process proceeds to the next process. On the other hand, if the current value of the display month storage register ya is 0 or more, the calendar of yd + ya year / month can be displayed, so that the process of step S39 is not executed and the process shifts to the next process. Note that, as described above, the initial value of the value of the display month storage register ya is 0,
Since the value is increased / decreased only by operating the previous month key and the next month key, naturally, the possible values are 0 ≦ ya ≦ A (1, r).
Is regulated in the range of.

Next, the PMC CPU 18 executes step S
Then, the process proceeds to 27, and the same as the above-mentioned one month based on the creation start year / month yd and the added value of the display month storage register ya and the value dmax. Of the final date corresponding to the year / month of the added value. After reading the minute calendar from the file and displaying it on the display screen of the manual data input device 29 with a display as shown in FIG. 11, the cursor designation index x is initialized to 1 and the cursor is moved to the position of x days on the display screen. Is displayed. Next, the values of the month deviation integration counter i and the total number of days integration counter ds of the nonvolatile memory 24 are initialized to 0 (step S28), and it is determined whether the value of the counter i is smaller than the value of the display month storage register ya. However, if the value of the display month storage register ya is larger than the initial value 0 of i, yd + ya> yd, which means that a calendar in the future from the creation start date yd is displayed. Therefore, the date value designated by the value of the cursor designation index x does not match the date data of the calendar stored in the address of the file corresponding to this value,
Since it is necessary to set the process control data by the date designation operation using the cursor in the subsequent processing, it corresponds to the date immediately before the first date of the month currently displayed on the display screen of the manual data input device with a display 29. It becomes necessary to obtain the address ds of the file. That is, the address of the file obtained by adding the value of the cursor designation index x and ds is the address of the file having the record corresponding to the date designated by the cursor.

In the processing of steps S30 to S31, the address on the file corresponding to the date immediately before the first date of the display month selected as the display target by operating the next month key and the previous month key is set as the value of the counter ds. This is a process for obtaining. That is, f (yd, i) is the value dmax. Of the final date of the month i months after the creation start date yd is R based on the added value of the creation start date yd and the month deviation i.
This is a function for reading from the OM13, and step S2
In the process from 8 to step S31, the initial value of the monthly deviation i is set to 0, and the value ds of all the final date values of each month from i = 0 to ya-1 is calculated to obtain the total day cumulative counter ds. Match the value with the address on the file that corresponds to the day immediately preceding the first day of the displayed month. As an example, the creation start date yd is August 1993, and the displayed month storage register y is displayed.
If the value of a is 2, then the calendar currently displayed on the display screen of the manual data input device with display 29 is that of October 1993, and f
(Yd, 0) is the last date of August 1993, 31 days, and f (yd, 1) is the last date of September 1993, 30.
Since these are days, the value of ds becomes 61 days when these are added, and the data of September 30, 1993, which is the date immediately before the first date of the displayed month, is the 61st day in the file of FIG.
Means that the cursor is at the address, for example, if the cursor on the display screen is x = 1, that is, on October 1, 1993, ds + x = 62, that is, the 62nd address in the file of FIG. October 1st
It means that the process control data for the day is set.

The PMC CPU 18 which has obtained a value ds obtained by integrating all the values of the last date of each month from i = 0 to ya-1.
Returns to the processing of step S3, and enters a standby state waiting for a key operation by the operator.

On the other hand, the operator who selects the year and month for which the process control data is to be set by operating the next month key and the previous month key and causes the display screen to display the calendar for one month is Data input device 2
9 Use the cursor movement keys to select the date for which data is to be set, and use the production control key, maintenance control key, and work schedule key to select the data item to be set, and then use the numeric keypad to operate. By selecting the display data for each item, the process control data is sequentially set in the data storage means composed of the records in the third, fourth and fifth columns of the file of FIG.

First, when the operator operates a cursor movement key which constitutes a part of the display data setting input means,
The PMC CPU 18, which repeatedly executes the determination process of step S3, step S32, step S36, step S40, step S42, step S48, step S54, and step S60, detects this operation in the determination process of step S40 and is operated. The value of the cursor designation index x is incremented or decremented according to the type of cursor movement key, for example, the type of up or down movement, and the cursor is moved to the display position of the date on the display screen corresponding to the current value of the index x. It is moved (above, step S41). Needless to say, the possible value of the index x is 1
To the dmax. Of the displayed month.

When the operator operates the production control key forming a part of the display data setting input means, the PMC
The CPU 18 for use detects this operation in the determination process of step S42, and associates the display data and the data number stored in the table F1 of FIG. 13 with each other as shown in FIG. While displaying on the screen (step S43), a guidance message such as "please enter the item number" is displayed (step S43), and a standby state waiting for the input of the item number is entered (step S45). Therefore, when the operator inputs an item number through the ten-key pad as the display data setting input means, the PMC CPU 18 detects this in the discrimination processing of step S45, and detects the input item number in the file (3 column, ds + x row). ) It is stored in the production control item storage record of the spot (step S46), and the display data of the table F1 corresponding to the item number is displayed at the production control item display position on the display screen corresponding to the date of the cursor present position and displayed to the operator. Confirm it (step S47).
If this operation is performed on a spot in which data is stored in advance, the data up to that point will be erased, the newly input item number will be stored, and new display data will be displayed at the current cursor position. When the item number 0 is input, the data of the spot is initialized to 0 and the data display at the current cursor position is erased.

When the maintenance management key and the work schedule key as the display data setting input means are operated, the table used is not F1 but F2 or F3, and the spot for storing the item number is (3). Row, ds + x
Row, not (4 columns, ds + x rows) or (5 columns, ds
+ X lines) and that the item display position corresponding to the date on the display screen is shifted to the right while avoiding duplication, which is different from when the production control key is operated, but the process flow itself Is completely the same as that described above, and therefore the description of the processing of steps S49 to S53 and steps S55 to S59 will be omitted. In addition,
The manual setting of the maintenance date is performed by the processing of steps S49 to S53, and the partial cancellation operation of the maintenance date and the new addition setting operation which are automatically set can be performed in the same manner.

Below, the operator appropriately moves the cursor to the display position of the date for which the process control data is to be set, and operates the production control key, the maintenance control key, and the work schedule key to select the type of data to be set. Selected,
By entering the item number with the numeric keypad, data regarding production, maintenance, and work can be set appropriately in the record at the address corresponding to each date. Further, if it is necessary to set the process control data for another month, the calendar of a desired year and month is newly displayed on the display screen of the manual data input device with display 29 by operating the next month key and the previous month key. Then, the data for process control is set by repeatedly executing the same operation as described above. Then, when the required setting action is completed, the end key is operated to end this function menu and complete the process related to the data setting.

When confirming the calendar set in the file of FIG. 14 in this manner, the operator operates the function keys of the manual data input device 29 with a display in the same manner as in the case of creating a calendar and setting data.
The function menu for process control is selected. As described above, since the calendar creation completion flag data, the creation start year / month storage register yd, and the display month storage register ya are all non-volatile registers, after the function menu selection and the determination processing of step S1 are executed, the PMC CPU 18 Will display the calendar for one month displayed at the end of the previous setting work on the display screen of the manual data input device 29 with a display based on the values of these registers. Therefore, if you want to know the process control plan for the same month, you only have to select the function menu, and if you want to know the process control plan for the future or past months, do the same as the previous month or the previous month in the same way as above. The displayed month can be changed by operating the keys as appropriate, and if there is a change in the plan in the middle, perform the same setting, resetting, or deleting operation as described above to save the part in the file. You can make a corrective correction. Of course, it is not necessary to set all the process control data for the first created calendar year at the time of completion of calendar creation, and set the process control data for later days according to the progress of the process control plan. Alternatively, if the storage period of the file has reached its limit due to the period up to the last date stored in the file, clear the file once and then operate the new creation key. Therefore, the process relating to the calendar creation may be performed again.

The value of the last date of each month of each year is stored in the ROM 13 in advance.
In order to create a file by updating the calendar for a predetermined number of r days as necessary, the storage capacity of the file is restricted to a predetermined number of r days and the memory capacity of the non-volatile memory 24 is reduced. Since it is for saving, the calendar automatic creation function (step S5 to step S1
6) is not always necessary, and the nonvolatile memory 24
It is also possible to provide a file having a calendar of a necessary period and a storage record corresponding thereto.

As the display data stored in the table F1 as the item of production control, "scheduled production completion date",
There are "delivery date", "machine stop", "production start date", etc., and display data stored in the table F2 as maintenance management items include "maintenance", "lubrication", etc. The display data stored in the table F3 as work management items include "holiday", "night work", and the like, and the content and number of these display data may be arbitrarily determined. Further, the data storage areas assigned to the tables F1 to F3 may be set in advance in the non-volatile memory 24, and the display data created by the user according to the convenience of the user may be stored in the non-volatile memory 24. Good. The display format of the calendar is not limited to that shown in FIG. 11, and may be displayed in a seven-day table as shown in FIG. 12, or if there is enough display space, calendars for multiple months may be displayed. You may make it display simultaneously.

In the embodiment described above, the scheduled production completion date in the production control item is set manually by operating the cursor movement key and the ten-key pad. However, the above-mentioned steps S46 and S47.
If the processes shown in FIGS. 9 and 10 are applied instead of the process of FIG.
It is also possible to automatically set the scheduled production completion date by the processing on the side.

The automatic setting process of the planned production completion date will be described below with reference to the flowcharts of FIGS. 9 and 10.

Similar to the case of the above embodiment, step S
The PMC CPU 18, which has detected the input of the item number of the production control item in the determination processing of 45, then sets the value of the item number to 4
Or not, that is, whether or not the production start date is set (step a1). And the value of the item number is 4
If it is a value other than, the PMC CPU 18 uses the entered item number of the file (3
(Column, ds + x row) is stored in the spot production control item storage record (step a2), and the display data of the table F1 corresponding to the item number is displayed at the production control item display position on the display screen corresponding to the date of the cursor current position. Then, the operator is asked to confirm (step a3), and the process shifts to step S3 as in the above-described embodiment, and again enters the standby state waiting for the operator's key operation.

When the item number value is 4 and the production start date is about to be set, the PMC CPU 18
Displays a guidance message on the display screen asking whether to automatically set the planned production completion date, and enters the standby state waiting for the operator to operate the function key for automatic setting or the function key for manual setting ( Step a4). At this time, if the function key for manual setting is operated, CP for PMC
U18 executes the processing of step a2 and step a3 in the same manner as described above, stores the input item number 4 in the production control item storage record of the spot (3 columns, ds + x lines) of the file, and corresponds to the item number 4. The display data of the table F1 to be displayed, that is, "production start date" is displayed at the production control item display position on the display screen corresponding to the date of the cursor current position to be confirmed by the operator.

On the other hand, when the function key for automatic setting is operated, the PMC CPU 18
Also displays a guidance message on the display screen asking whether or not the machine stop data setting in the production control items has been completed, and the Y key (meaning that the machine stop data has been set) or the N key (machine A standby state waiting for an operation of "stop data not set" is entered (step a5). Therefore, the operator operates either the Y key or the N key based on his / her own judgment, depending on whether or not the data setting of the machine stop is completed. As a matter of course, when the injection molding machine is not scheduled to be stopped, the operator operates the Y key even when the machine stop data is not set.

If the N key is operated at this time, it means that the setting operation has not been executed although the machine stop data setting is necessary.
U18 displays a guidance message on the display screen to execute the data setting of the machine stoppage before the automatic setting of the planned production completion date, and shifts to the standby process of step S3 (step a15) to inform the operator of the data of the machine stoppage. Set the settings first. In this case, the operator sets the machine stop data in the same manner as in the above-described embodiment, again sets the cursor to the date corresponding to the production start date, operates the production control key, and uses the ten-key pad to enter the item number 4 Is designated, and the function key and Y key for automatically setting the planned production completion date are operated.

Then, when the Y key is operated, the PMC CPU 18 sets the input item number 4 to (3
(Column, ds + x row) is stored in the production management item storage record of the spot (step a6), and the display data of the table F1 corresponding to item number 4, that is, "production start date" is displayed on the display screen corresponding to the date at the current position of the cursor. It is displayed at the above production control item display position for operator confirmation (step a7), and a guidance message such as "Enter molding cycle time" is displayed on the display screen (step a8). A standby state waiting for the input of the molding cycle time by operation is entered (step a9). PM that detected input of molding cycle time
The CPU 18 for C temporarily stores the molding cycle time in the register C (step a10), and then displays a guidance message such as "Please input the number of shots to be produced" on the display screen (step a11). When the operator enters the number of shots via the ten-key pad while waiting for the input of the number of shots by the ten-key operation (step a12), this value is temporarily stored in the register S (step a13). Then PMC
The CPU 18 calculates the total required time Cs required from the start of production to the end of production by multiplying the values of the registers C and S (step a14), and determines the address ds + x of the record in which the production start date is set as the address search index i. Is set as an initial value (step a16).

Then, the PMC CPU 18 determines that the current value of the address search index i is the final address r in the file.
Is exceeded (step a17), or a numerical value 3 (table F in FIG. 13) for storing the machine stop from the production control item storage record of the spot (3 columns, i row) of the file.
1) is detected (step a18), the value of the address search index i is sequentially incremented (step a19), and each time, the operation of the injection molding machine for one day is started from the current value of the total required time Cs. The time set value Ts is subtracted and updated and stored in the register Cs (step a20).
It is determined whether or not the value of s is subtracted to less than 0 (step a21), and if it is not less than 0, the processing of steps a17 to a21 is repeated in the same manner. Further, by setting a peculiar operating time for each date in advance, it is possible to perform a calculation in consideration of conditions such as half-day operation. In this case, a record for setting and storing the operating time set value Ts for one day is added to the sixth column of the file means as shown in FIG. 14 to set the operating time Ts for each date. In the processing, the data of A (6, i) is read based on the current value of the address search index i, and this value is subtracted from Cs.

Therefore, every time after the address ds + x of the file corresponding to the production start date and after the address of the day on which the injection molding machine operates, injection is performed from the total required time Cs required from the start of production to the end of production. The operating time Ts for one day of the molding machine is subtracted, and if the value of the register Cs becomes less than 0, it means that the production for the number of production shots is completed in any time zone of the day. To do. The PMC CPU 18 completes production in the production management item storage record of the spot (3 columns, i rows) of the file corresponding to the address i of the file detected when the value of the register Cs becomes smaller than 0. The numerical value 1 (refer to the table F1 in FIG. 13) indicating the display data of the scheduled date is stored (step a22), and the automatic setting process of the scheduled production completion date ends. Since the planned production completion date is not necessarily within the same month as the production start date, the planned production completion date will not be displayed in correspondence with the calendar date currently displayed on the display screen, Step a22
A message such as "automatic setting completed" is displayed along with the execution of the process of A, and A (1, i), A in the file is displayed.
It is possible to display the data (2, i), that is, the date when the production is scheduled to be completed. Also, step a
It is determined whether or not the value of the index i at the time of executing the process of 22 is smaller than the sum of ds and dmax. Of the displayed month, and only when it is smaller, the production on the display screen corresponding to the date of i-ds You may make it display the scheduled production completion date of the item number 1 in the management item display position.

On the other hand, if the determination result of step a17 becomes false while the processes of steps a17 to a21 are repeatedly executed, the number of shots to be produced is planned even if production is continued until the date stored in the final address in the file. C for PMC because it means that the production of minutes is not completed
The PU 18 displays on the display screen a message such as "The production completion date cannot be specified" or "The production completion date will be A (1, r), A (2, r) or later" (step a23), The automatic setting is abandoned and the process ends.

As described above, it is necessary to create a calendar over a predetermined period, register process management data corresponding to each month and day of the calendar, and display the correspondence between the calendar and process management data for each month. Although an example in which all of the processing to be performed is performed by the control device 10 on the injection molding machine side, a host computer such as a cell controller arranged in a molding factory and a control device 10 for a plurality of injection molding machines are connected. In such a case, the host computer and the controller 10 of the injection molding machine may be used together to realize these functions.
For example, as shown in FIG. 14, it is constituted by creating calendars to be stored in the records in the first and second columns and the records in the third, fourth and fifth columns in the file means on the control device 10 side. All the process management data for each injection molding machine to be stored in the data storage means are created on the host computer side, and the calendar and the process management data for each injection molding machine are created for each control device 10 of each injection molding machine. Alternatively, the control device 10 may display only the calendar for each month by operating the next month key or the previous month key. In this case, step S4 of the above embodiment
~ The host computer is caused to perform the calendar creation process as shown in step S18, and the memory of the host computer stores data for each injection molding machine, for example, a production management item storage record and a maintenance management item storage for each injection molding machine. A record, a work management item storage record, and the like are provided, and the data storage means for each injection molding machine corresponds to each processing of step S32 to step S39, step S27 to step S31, and step S40 to step S59 of the above-described embodiment. The process management data is registered to register the process management data, and the process management data is downloaded corresponding to each injection molding machine.

Further, common data (work schedule, etc.) is transmitted to a plurality of injection molding machines, a plan for the entire factory is created by the host computer, and the data for each injection molding machine corresponding to the data is prepared. It can also be transmitted for each.
