[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work data registration system for an injection molding machine.

[0002]

2. Description of the Related Art A daily report type is generally adopted as a method for collecting inspection data on molded articles and molding operations.

[0003]

According to the method of collecting inspection data by daily report, a predetermined recording sheet in which a scheduled inspection time is entered and a memo field is provided is always provided near the injection molding machine, or this sheet is kept. It is handed over to the operator in advance, and the operator refers to his / her own clock to perform a sampling inspection of the molded product at the specified scheduled inspection time, and the inspection result is entered in the memo field of the paper. There is a tendency to lack objectivity because the procedure for filling in the results varies depending on the operator's interpretation, and it is all based on the operator's self-declaration whether or not the sampling inspection has been performed at the specified scheduled inspection time. However, it was not always possible to expect sufficient reliability, and it was difficult to check for missing inspections.

Therefore, an object of the present invention is to ensure uniform inspection data irrespective of the operator's individuality, and to properly store the time at which the inspection is carried out. To provide a registration method.

[0005]

According to a work data registration system of an injection molding machine according to the present invention, a series of inspection items relating to a molded product and a molding operation are stored in advance in a control device of the injection molding machine, and an inspection data input screen is displayed. When is selected, the previously stored inspection items are displayed on the screen of the display device,
The above-mentioned object was achieved by inputting the inspection result for each inspection item in an interactive manner and storing it in the storage means of the control device, as well as storing the current time.

Further, by storing the inspection scheduled time together with a series of inspection items relating to the molded product and the molding operation in the control unit of the injection molding machine, and displaying the scheduled inspection time together with the inspection item when the inspection data input screen is selected. Inform the operator of the time when the inspection should be performed.

When collecting work data corresponding to a plurality of injection molding machines, a host computer is connected to each injection molding machine via a data transmission line, and the molding products and molding work set for each molding product are related. An inspection item file that stores a series of inspection items is provided in the host computer, and by inputting a selection command on the inspection data input screen to the injection molding machine, the inspection item data corresponding to the molded product molded by the injection molding machine is displayed. It is downloaded from the inspection item file of the host computer to the injection molding machine and displayed on the display device of the injection molding machine, and the inspection result regarding each inspection item input interactively to this injection molding machine is stored in the storage means of the host computer. Transfer it to the inspection data storage file for each injection molding machine provided inside and store it together with the current time To.

Furthermore, when the inspection result is manually input, the current value of the state storage means of the injection molding machine is automatically read and stored together with the input inspection result in the storage means of the control device or the inspection data storage file of the host computer. The state of the injection molding machine at the time of the inspection is also saved together with the input inspection result.

[0009]

The control device of the injection molding machine, which has detected the selection operation of the inspection data input screen, reads a series of inspection items and the scheduled inspection time stored in advance in the control device or the host computer and displays them on the display screen of the injection molding machine. Display and wait for manual input of inspection results for each inspection item.

When the operator inputs the inspection result concerning each inspection item in an interactive form, the input inspection result is transferred to the inspection data storage file for each injection molding machine provided in the storage means of the control device or the host computer. It is stored together with the time.

Further, when the inspection result is manually input, the current value of the state storage means of the injection molding machine is transferred to and stored in the storage means of the control device or the inspection data storage file of the host computer together with the input inspection result.

Since the inspection result is input interactively, the evaluation of the inspection result is binary and the discretion by the operator's interpretation is limited, and a uniform inspection result can be obtained. Further, since the time at which the inspection is performed is stored mechanically regardless of the operator's intention, it is difficult to tamper with the inspection time, and the reliability of the data is improved.

And the molding machine number A together with the current value T of the clock device.
i is transferred to the control device 100 (step T2). The array of inspection results in the inspection data storage file FSN is stored as an array of 1s and 0s, as in the transfer data storage table shown in FIG.

Then, the PMC CPU 114, which has detected the reception of the transfer data from the host computer 300 in the determination processing of step S9 in the inspection data input processing,
Shared RAM for each value of the partial file Fc ', the partial file Fs', the partial file FSN', and the current value T of the clock device
The data request flag is temporarily stored in the transfer data storage area 105 and the data request flag is reset (steps S10 and S11), and the CRT / MDI 119 is displayed based on the values of the transferred inspection item number Ki and scheduled inspection number Mi. A table column as shown in FIG. 14 is created on the screen (step S1
2) Display each value of the scheduled inspection times Li, 1 to Li, Mi read from the partial file Fc 'in each column of the scheduled inspection time to inform the operator of the time at which the inspection should be performed, and the clock device. The value of the inspection execution time of the partial file FSN ′ having the date that matches the date T1 of 1 and the inspection result, that is, the execution time of the inspection performed on the day and all the inspection results corresponding thereto are all recorded in the execution time column. And each item of the inspection item columns 1 to Ki, and further, each value of the product data Ci to Hi read from the partial file Fc 'is displayed as the product data under production, and the time at the current value T of the timepiece device is displayed. The value of the minute portion T2 is displayed on the next line of the implementation time column to inform the present time (step S13). Regarding the inspection results of the inspection item columns 1 to Ki, when the result stored in the array of the partial file FSN 'is 0, "OK" is displayed,
When the value of the result is 1, "NG" is displayed, and when the non-execution code is stored in the inspection execution time storage area of the partial file FSN ', "non-execution" is displayed in the execution time column. Then, the columns of the inspection item columns 1 to Ki are hidden.

For example, the non-volatile RA set for the injection molding machine 200 whose molding machine number Ai is 001S.
If the inspection item file Fc of M304 (file Fc 'in the shared RAM 105) is in the state as shown in FIG. 4, the column of the scheduled inspection time in the CRT / MDI 119 has a total of Mi rows, that is, 12 rows. , In each column, 9:00, 10:00, 11:00, ..., 20: 0
A value of 0 is displayed. Further, the inspection data storage file FSN (file FSN 'in the shared RAM 105) corresponding to this injection molding machine has been written up to the second line in the state as shown in FIG. / 1
The data array from 1 to Ki of the inspection result of 9:05 in 5 is all 0, 0, 0, ... And 10:
If the non-execution code is written in the inspection execution time column corresponding to the scheduled inspection time of 00, CRT / MDI

“Non-execution” is displayed in the execution time column corresponding to 0:00, and all the inspection item columns are in the non-display state. Further, as the respective values of the product data Ci to Hi, gear, AX203,
..., Level 2 is displayed, and further, the next line of the execution time column in the CRT / MDI 119, that is, the scheduled inspection time 11:00
In the execution time column corresponding to 0, the value of the hour / minute part T2 in the current value T of the timepiece device, for example, 11:01 is displayed.

Next, the PMC CPU 114, which has initialized the transfer data storage table (FIG. 15) of the shared RAM 105 and set the item index j to 1 (steps S14 and S15), displays the update of the inspection item in the state storage flag F. Is set to a value of 2 and the processing of the cycle ends (step S16).

Since the state storage flag F is set to 2 in the inspection data input process of the next cycle, the PMC CPU 1
After executing the discrimination processing in step S1 and step S2, reference numeral 14 indicates, based on the value of the item index j, display items at the time of inspection corresponding to the code stored in the inspection item Ji, j of the partial file Fc 'from the partial file Fs'. Call and CRT / MD
It is displayed in the inspection request display field of I119 (step S1).
7). For example, if the value of the molding machine number Ai of this injection molding machine is 001S and the value of the index j at this stage is 1, the value of the inspection item Ji, j becomes J1,1 and the corresponding code Since the value of is C1, "Is the product on schedule?" Is displayed.

The PMC CPU 114, which has displayed the items to be inquired in the inspection request display field, detects the operation of the soft key or screen selection key by the operator. If no key operation is detected, step S18 is performed. ，
After executing the determination processing in steps S19 and S25, the state storage flag F is set to the value 3 indicating that the manual input is on standby, and the processing of the cycle ends (step S26), and the display state of the inspection request is maintained. The same discrimination process is repeatedly executed in the inspection data input process in the next period and thereafter to wait for the operation of the "OK" key or the operation of the "NG" key or the selection of another screen.

The operator refers to the display screen of the CRT / MDI 119 and refers to the value of the current time T2 displayed in the execution time display field and the value of the inspection scheduled time display field corresponding to the execution time display field, If the value of the current time T2 is substantially coincident with the scheduled inspection time, the molded product for one shot discharged from the injection molding machine at this stage is inspected, and the CRT /
The "OK" key or the "NG" key of the CRT / MDI 119 is operated in response to the questions displayed in the examination request display column of the MDI 119 in sequence. In the example shown in FIG. 14, the value of the current time T2 displayed in the execution time display field is 11:01, and the value of the corresponding scheduled inspection time display field is 11:00. Then enter the inspection results. Further, in this embodiment, the current time is ± ΔT with respect to the predetermined scheduled inspection time.
Input of inspection data is allowed within the range (for example, ± 10 minutes), and if the data input screen is mistakenly selected in other time zones, and to confirm the scheduled inspection time, etc. If you make the above display process,
The inspection of the molded product and the input of the inspection data are not performed, and another screen is selected, and the inspection data input process is terminated as it is.

The value of the current time T2 substantially coincides with the scheduled inspection time, and the operator who inspects the molded product is CRT / MDI1.
"OK" key or "NG" for 19 inspection requests
When the PMC CPU 114 responds by operating the keys, the PMC CPU 114 detects these key operations in the determination processing of step S18 or step S19 that is repeatedly executed.

When it is judged that there is no abnormality in the inspection request being displayed by the operation of the "OK" key, the PMC CPU
After displaying the character "OK" in the j-th column of the inspection item display column corresponding to the display line of the current time T2 in the CRT / MDI 119 (step S27), the current value of the item index j is the number Ki of items. Is reached, that is, whether the answers to all the inspection items have been completed (step S22). If the answers have not been completed, the value of the item index j is incremented and the status is increased. The memory flag F is reset to 2 (step S23, step S2
4) The processing of this cycle is completed. When it is determined by the operation of the "NG" key that the inspection request being displayed is abnormal, the PMC CPU 114 sets 1 in the jth column of the inspection result column of the transfer data storage table as shown in FIG. Is set, and the letter "NG" is displayed in the jth column of the inspection item display column corresponding to the display line of the current time T2 on the CRT / MDI 119 (step S20).
It is determined whether or not the command corresponding to the inspection item Ji, j of the partial file Fs' stores a command for injection molding machine discontinuation (step S21). Then, if the command to stop the production is not stored, the processing of steps S22 to S24 is executed in the same manner as described above, and the item index j
Value is incremented and the state memory flag F is set to 2
Is reset and the processing of this cycle is completed.

When the state storage flag F is reset to 2 in this way, the PMC CPU 114 executes the determination result processing of steps S1 and S2 of the next cycle, and then sets the updated value of the item index j. Based on step S again
17 is executed, and thereafter, in the same manner as described above, until the value of the item index j reaches the item number Ki, CRT / MD
A new inspection request is sequentially displayed on I119, and waiting for the input of the inspection result by the "OK" key or the "NG" key,
The inspection result is sequentially stored in the transfer data storage table. The value of the item index j is the number of items Ki.
When it is confirmed that the input operation for all the inspection requests is completed (step S22), the PMC CPU
Reference numeral 114 sets the value of the alarm number integration counter Cx and the value of the production number integration counter Cy in the transfer data storage table, resets the value of each counter (steps S29 and S30), sets the data transfer flag, and stores the state. The flag F is set to the value 4 indicating that the transfer output is on standby, and the processing of the cycle is finished (steps S31 and S3).
2).

Even if the input operation for all the inspection requests is not completed, the code corresponding to the inspection request is added at the stage when it is determined that the inspection request is abnormal by the operation of the "NG" key. When it is determined that the command to stop the production is stored, for example, when the “NG” key is operated in response to the inspection request of the codes C1 and C2, the PMC CPU 114 performs the determination process of step S21. After execution, the contents of the abnormality are displayed on the display screen of the CRT / MDI 119, and an alarm is output to the injection molding machine to stop the operation in the mold open state (step S28), and the value of the alarm number integration counter Cx and the production number integration are integrated. After setting the value of the counter Cy in the transfer data storage table and resetting the value of each counter (steps S29 and S3)
0), the data transfer flag is set and the state storage flag F
A value of 4 indicating that the transfer output is on standby is set in, and the process of this cycle is ended (steps S31 and S32). Therefore, when the inspection result that requires the operation of the injection molding machine is input, all the display of the inspection request regarding the subsequent inspection items is ignored, and the injection molding machine is immediately stopped at this stage, In addition, only the results of tests performed before this are valid.

When the input of the inspection result is completed and the data transfer flag is set (step S31), the state storage flag F is set.
When the value 4 indicating that the transfer output is on standby is set (step S32), the PMC CPU 114 repeatedly executes the determination processing from step S1 to step S4 and step S33 in the inspection data input processing after the next cycle, A standby state waiting for polling from the computer 300 is entered. In the input example of the inspection result at 11:01 as shown in FIG. 14, the third inspection item, that is, the code C11.
Since the inspection result is "NG" only for the inspection item "is there a burr?" Corresponding to, the value of the inspection result in the transfer data storage table is 0,
0, 1, 0, 0, ...

When the reading of the transfer data storage table by the host computer 300 is completed (step S33), the PMC CPU 114 resets the data transfer flag (step S34), and then sets the state storage flag F to the standby state for the end processing. The indicated value 5 is set and the processing of the cycle is ended (step S35), and the CRT / MDI1 is set.
While maintaining the current display state in step 19, step S1
Only the determination process of step S5 and the determination process of step S36 are repeatedly executed. However, when the selection of another screen by the screen selection key is detected in the determination process of step S36, the value of the state storage flag F is initialized to 0. (Step S3
7) Then, the processing shifts to the processing of the corresponding selection screen.

On the other hand, the CPU of the host computer 300
301 sequentially calls the control device 100 of the injection molding machine 200 of each molding machine number Ai by polling processing,
Whether the data request flag is ON (step T
1), the scheduled inspection time L at which the next inspection is to be performed, which is indicated by the next value Ni + 1 of the inspection number integration counter Ni (initial value 0)
Whether or not the current time T2 is delayed with respect to i, Ni + 1 by a delay of the allowable set value ΔT or more (step T3), whether or not the data request flag is ON (step T4), and the output request signal is input. It is determined whether or not (step T8) every predetermined period, and if the data request flag is ON, the process of step T2 is performed as described above to transfer the data to the control device of the injection molding machine, and If it is determined in step T3 that a delay of the allowable set value ΔT or more has occurred, that is, if the inspection data is not input within ΔT after the scheduled inspection time, the inspection number integration counter
After incrementing the value of Ni (step T9), the next record of the inspection data storage file FSN of the injection molding machine Ai shows the value of the current date T1 and the non-execution code, and the scheduled inspection time Li, Ni in the inspection item file Fc. And the name Ci, the product number Di, and the planned production quantity Ii are registered (step T10).

Further, when the CPU 301 detects that the data transfer flag of the control device is set (step T4), the Ni + 1-th scheduled inspection time Li corresponding to the molding machine number Ai from the inspection item file Fc, The value of Ni + 1 is read, and the input time T2 of the transfer data from the injection molding machine Ai is the allowable set value ΔT (for example, 1 for the scheduled inspection time Li, Ni + 1).
It is determined whether or not it is ahead by more than 0 minutes (step T5), but if it is not ahead by more than the allowable set value ΔT, the value of the inspection number integration counter Ni is incremented and a new inspection result is registered. After storing the execution (step T
6), the inspection result by the transfer data of this time, that is, the value of the transfer data storage table is registered in the next record of the inspection data storage file FSN of the injection molding machine Ai, and the value of the current date T1 generated by the timepiece device. And inspection time T2
Value, the values of the scheduled inspection times Li and Ni in the inspection item file Fc, the name Ci, the product number Di and the planned production quantity Ii, and the integrated value and the alarm of the production quantity Cx read from the transfer data storage table. The incremental amount of the number of occurrences Cy is registered (step T7).

For example, as shown in FIG. 4, 9:00, 10:00, 11:00 for the molding machine number 001S.
When the inspection result is set to 0, ... And the allowable set value ΔT is set to 10 minutes, 91/06/1
Input of the actual inspection result at 5 points is 8:55, 1
If it is executed at 0:15, 11:01, the CPU 30
The processing of 1 causes the following phenomenon.

In the initial stage, the inspection number integration counter Ni
Since the value of is 0, in the process of step T3, first,
A value 9:10 obtained by adding 10 minutes to the scheduled inspection time 9:00 at the scheduled inspection time Li, 1 and the current time T2 are compared at predetermined intervals. The result of this determination is that the value at the current time T2 is 9 : 1
Until it exceeds 0, it is always false. And 8:55
At the stage when the first inspection result is input, the transfer data input time is 8:55 and the first inspection scheduled time is 9: 0.
Since 0 is not preceded by 10 minutes or more (step T
5) At this stage, the value of the inspection number integration counter Ni is incremented to 1 (step T6), and this time's transfer is made to the first record (initial position) of the inspection data storage file FSN of the injection molding machine Ai. The inspection result based on the data and the value of the current date T1 generated by the timepiece device 91/06 /
15 and the value 8:55 of the inspection execution time T2, and
The scheduled inspection time Li, 1 in the inspection item file Fc is 9:00, the name Ci is the gear, and the part number Di is AX203.
Further, the planned production quantity Ii of 10000, and further, the integrated value of the production quantity Cx read from the transfer data storage table and the incremental amount of the alarm occurrence frequency Cy are registered (step T7, see FIG. 6).

As a result of the value of the inspection number integration counter Ni being incremented to 1, step T3 in the next period and thereafter.
In the process of, the scheduled inspection time of the scheduled inspection time Li, 2 is 10:
The value 10:10 obtained by adding 10 minutes to 00 and the current time T2 are compared at predetermined intervals, but in this case, the second
Since the determination result of step T3 becomes true before 10:15 when the second inspection result is input, the value of the inspection number integration counter Ni is incremented to 2 when the current time T2 exceeds 10:10. (Step T9), in the next record of the inspection data storage file FSN of the injection molding machine Ai, that is, the second record, the current date T1 generated by the timepiece device.
Value 91/06/15 and non-execution code, and the value 1 of the scheduled inspection time Li, 2 in the inspection item file Fc
0:00 and the name Ci and the part number Di AX203
In addition, 10000 of the planned production quantity Ii will be registered (step T10, see FIG. 6). In this case, the transfer input of the inspection data is regarded as an illegal operation, the inspection result is not registered, and the value of the inspection number integration counter Ni is incremented to 2, which results in 10:10 to 10: 5.
All input operations up to 0 are invalidated by the determination processing in step T5.

Then, step T3 in the next period and thereafter.
In the process of, the scheduled inspection time Li, 3 is the scheduled inspection time 11:
The value 11:10 obtained by adding 10 minutes to 00 and the current time T2 are compared at every predetermined cycle. However, at the stage when the third inspection result is input at 11:01, the transfer data is input. Time 11:01 is the scheduled third inspection time 11:00
0 is not preceded by more than 10 minutes (step T
5) Further, since the third scheduled inspection time 11:00 is not delayed by 10 minutes or more, the third record of the inspection data storage file FSN is in an unregistered state (step T3, step T9). , Step T10). Therefore,
At the stage when the third inspection result is input at 11:01, the value of the inspection number integration counter Ni is incremented to 3 (step T6), and the next record of the inspection data storage file FSN of the injection molding machine Ai, that is, , In the third record, the inspection result values 0, 0,
1.0, and the value 91 of the current date T1 generated by the timepiece device
/ 06/15 and the value of inspection execution time T2 11:01,
Also, the value of the scheduled inspection time Li, 3 in the inspection item file Fc is 11:00 and the name Ci and the part number Di
AX203, the planned production quantity Ii of 10000, and the cumulative value of the production quantity Cx read from the transfer data storage table and the incremental amount of the alarm occurrence frequency Cy are registered (step T7, see FIG. 6).

Hereinafter, the CPU of the host computer 300
301 is the scheduled inspection time Li, Ni + 1 at which the next inspection should be performed.
Whenever the inspection data is input at an appropriate time, the inspection result is registered in the next record of the inspection data storage file FSN of the injection molding machine Ai, and if the inspection data is not input at the appropriate time, it is not executed. You will be writing the code. Then, when the process of the next day is started, the value of the inspection number integration counter Ni is initialized, the same process as described above is repeatedly executed, and the next inspection record of the 91-th / 15th Mi-th inspection record is stored. From record next day 91/06
Although the inspection data of / 16 will be registered, the value of the date data T1 in the inspection data storage file FSN will be automatically updated in synchronization with the date update of the timepiece device.

Then, in the determination processing of step T8, the CRT
When a data output command from the keyboard of / MDI119 is detected, the CPU 301 displays the contents of the inspection data storage file FSN set corresponding to the injection molding machine whose molding machine number is specified by the keyboard on the display screen of CRT / MDI119 or It will be output via the printer 308. In the column of the inspection result of the inspection data storage file FSN,
The value of the transfer data storage file at the time of data transfer is stored as is, but when outputting the data,
By referring to the code array of the inspection item in the inspection item file Fc of the corresponding molding machine number and the corresponding code of the inspection item selection file FS, the display items at the time of outputting the result are output only for the items in which the abnormality is detected Therefore, it is easy to confirm the inspection result (step T1).
1).

For example, in the example of FIG. 6, when the inspection result corresponding to the inspection scheduled time 11:00 on 91/06/15 is output, the values of the inspection result are registered as 0, 0, 1, 0, .... Accordingly, the display item of “Cause investigation with burrs” corresponding to the third code C11 of the inspection item in the inspection item file Fc is output. CRT /
The display screen of the MDI 119 or the content of the data output from the printer 308 is substantially the same as that shown in FIG. 6 except that the specific test result is displayed in the test result column. When all the inspection result values stored in the records of the inspection item file Fc are 0, 0, 0, 0, ..., “OK” is output in the inspection result column while the inspection is performed. When the non-execution code is stored at the time, "non-execution" is output in the inspection execution time column, and nothing is displayed in the inspection result column.

Further, when outputting the inspection data storage file FSN, it is possible to specify the date when the output is started or the range of the output date. Since it can be easily applied, it will not be described in particular.

When the determination result of step T5 in the embodiment becomes false, the host computer 300 outputs a detection signal of illegal input to the injection molding machine of the molding machine number Ai, and the display screen of the CRT / MDI 119 is displayed. It is also possible to display an alarm message such as "illegal inspection after hours" to alert the operator. In the embodiment, the input of the result for the inspection item is performed by the "OK" key or the "N".
Since it is a two-way interactive mode by operating the G "key, homogeneous inspection data can be collected regardless of the operator's individuality, but the input of inspection results is" excellent ",
By providing keys such as “Good”, “OK”, ... “No”, and inputting the inspection result in an interactive manner by operating these keys, it is possible to obtain uniform inspection data in multistage evaluation. Further, a clock device and various file means are provided on the control device 100 side of the injection molding machine, and the PMC CPU 11
If only 4 is used to perform the same processing as described above, the same operation and effect as described above can be obtained by a single injection molding machine.

In the above-described embodiment, in order to perform the inspection at an appropriate time without delay or advance according to the preset scheduled inspection time, the inspection result is input in a time zone that is largely different from the scheduled inspection time. Although it is prohibited, if it is enough to store the inspection time and the inspection result in an appropriate manner, it is not necessary to limit the inspection time and the scheduled inspection time. If you don't get caught, you don't have to display the scheduled inspection time.

In the above embodiment, the alarm number integration counter and the production number integration counter were described as an example of the state storage means of the injection molding machine, but the values of the other state storage means in the injection molding machine are used as the execution time of the product inspection. It is also possible to store in correspondence with the above, and the type of inspection item is not limited to the above example.
