It is registered that "30" lots of products of "D" and size "M" will be input.

FIG. 9 is a flowchart showing a lot number issuing process performed by the lot number issuing means 12 when the lot number of the configuration example shown in FIG. 2 is issued. Table 1, the production line management table 4, the lot number system table 10, and the input lot management table 7 have the contents shown in FIGS. 3, 4, 5, and 8, respectively, as an example. The lot number issuing processing operation will be specifically described.

First, among the number-of-numbering records registered in the input-lot management table 7 by the numbering-main processing means 13, the first number of numbering-target records (production line, product name, size, Is stored in the parameter management table 14, and an unprocessed lot is set (step P1).

Next, the lot number setting area is initialized by the numbering main processing means 13 (step P2), and subsequently, the number of numbering lots (number of lots stored in the numbering lot number column of the parameter management table 14). The number of the current lot is set up (step P3). In the case of this example, the parameter management table 14 is as shown in FIG.

Next, the record of the element number 1 (crown symbol) of the lot number system table 10 is acquired by the numbering main processing unit 13, and the record is obtained by referring to the acquisition unit column of the acquisition information column of the lot number system table 10. The means is activated (step P4). In this example, since "fixed" is described in the acquisition means column, the fixed acquisition means 16 is activated, and the fixed acquisition means 16 causes the lot number system table 1
The fixed character in the fixed character information column of 0 is acquired as a character string (step P5). In this example, “LOT” is acquired. Then, the character string "LOT" output from the fixed acquisition means 16 and the character string previously output and combined are combined by the character string combining means 21 (step P6). In this case, since there is no character string previously output, the character string combination result is “LOT” and stored in the lot number setting area.

Next, the record of the element number 2 (separator character) of the lot number system table 10 is acquired by the issue number main processing unit 13 and acquired by referring to the acquisition means column of the acquisition information column of the lot number system table 10. The means is activated (step P4). In this example, since “fixed” is described in the acquisition unit column, the fixed acquisition unit 16 is activated, and the fixed acquisition unit 16 acquires the fixed character in the fixed character information column of the lot number system table 10 as a character string. (Step P5). In this example, "-" is acquired, and the character string "-" output from the fixed acquisition means 16 and the character string "LOT" in the lot number setting area previously output are output by the character string combining means 21. Be combined. The character string combination result is "LOT-" and is stored in the lot number setting area.

Next, the record of the element number 3 (manufacturing line) of the lot number system table 10 is acquired by the issuing number main processing unit 13, and the record is obtained by referring to the acquisition unit column of the acquisition information column of the lot number system table 10. The means is activated (step P4). In this example, since “acquisition means” is described as “table reference”, the table reference acquisition means 17 is activated and the lot number system table 10
The character string is acquired by referring to the reference character information column (step P7).

In this example, "parameter management" is described in the table name column of the reference item information column, and "manufacturing line" is described in the item name column. Is searched, and “I” is acquired as “Manufacturing line”. Then, the character string “A” output from the table reference acquisition unit 17 and the character string “LOT-” in the lot number setting area that has been output and combined in advance are combined in the character string combining unit 21. (Step P6). The string combination result is "LOT-
A) and stored in the lot number setting area.

Next, the record of the element number 4 (product type) of the lot number system table 10 is acquired by the numbering main processing unit 13 and acquired by referring to the acquisition unit column of the acquisition information column of the lot number system table 10. The means is activated (step P4). In this example, since "table reference" is described in the acquisition means column, the table reference acquisition means 17 is activated, and the table described in the reference item information section of the reference character information section of the lot number system table 10 is activated. A character string is obtained from the item name (step P7).

In this example, "product information management" is described in the table name column of the reference item information column, and "product type" is described in the item name column. The product type column is referred to. In this case, “α”, “β”, and “γ” are registered as product types,
"Product type" cannot be specified. Therefore, in this case, the “product type” is specified using the description in the reference item specifying information column of the lot number system table 10.

In this example, the "specified item name" column of the specific information 1 column indicates "product name" (this indicates "product name" in the product information management table item), and the specific information column of the specific information 1 column indicates "product name". "Parameter management" in the table name column, specific information 1
In the item name column of the specific material column of the column, `` Product name '' is described,
“Size” (this indicates “size” in the product information management table item) in the specified item name column of the specific information 2 column, and “Parameter management” in the table name column of the specific material column of the specific information 2 column. "Size" is described in the item name column of the specific information 2 column.

Therefore, in this case, the parameter management table 14 and the product information management table 1 are combined based on these pieces of information, and the items “product name” and “size” of both tables become the combination key. “Product type” in the information management table 1 is specified. Here, “AAAA” in the product name column of the parameter management table 14
“S” in the size column of the parameter management table 14 is information on the combination source of the product information management table 1.

When a combination search is performed on the product information management table 1 based on these pieces of information, in this example, “α” is obtained as the product type. Then, the character string “α” output from the table reference acquisition unit 17 and the character string “LOT-A” in the lot number setting area that has been output and combined in advance are combined in the character string combining unit 21. (Step P6). The result of the character string combination is “LOT-α”, which is stored in the lot number setting area.

Next, the record of the element number 5 (material type) of the lot number system table 10 is acquired by the numbering main processing unit 13 and acquired by referring to the acquisition unit column of the acquisition information column of the lot number system table 10. The means is activated (step P4). In this example, since “external module” is described in the acquisition section, the external module reference acquisition section 20 is activated, and the external module name indicated in the external module name section of the reference character information section of the lot number system table 10 is activated. A character string is obtained from the module (step P8).

In this example, the lot number system table 10
"M01" in the external module name column of the reference character information column
(Meaning Module01)
String is obtained from 1. In this example, assuming that "B" is obtained, the character string "LOT-A" in the lot number setting area which is output and combined with the character string "B" output from the external module reference acquisition means 20 in advance. α ”are combined by the character string combining means 21 (step P
6). The character string combination result is “LOT-aαB”, which is stored in the lot number setting area.

Next, the record of the element number 6 (separator character) of the lot number system table 10 is acquired by the issuing number main processing unit 13, and the record is obtained by referring to the acquisition unit column of the acquisition information column of the lot number system table 10. The means is activated (step P4). In this example, since “fixed” is described in the acquisition unit column, the fixed acquisition unit 16 is activated, and fixed characters are acquired from the fixed character information column of the lot number system table 10 (step P5). In this example, "-" is acquired, and a character string "-" in the lot number setting area, which is output and combined in advance, with a character string "-" output from the fixed acquisition means 16, is used. Are combined in the character string combining means 21 (step P
6). The result of the character string combination is “LOT-i αB-”,
Stored in the lot number setting area.

Next, the record of the element number 7 (year) in the lot number system table 10 is acquired by the numbering main processing unit 13, and the record is obtained by referring to the acquisition means column of the acquisition information column of the lot number system table 10. The means is activated (step P4). In this example, since “system date and time” is described in the acquisition unit column, the system date and time acquisition unit 18 is activated to acquire the system date and time (current date and time). Since the digit position and the number of digits at the start of the acquisition are described, the year is acquired in accordance therewith (step P9).

Here, the system date and time is "19999093".
0130000 ”(13:00:00 on September 30, 1999), three years from the left as“ year ”
The "99" in the fourth and fourth digits is obtained. The character string combining means 21 combines "99" output from the system date and time acquiring means 18 and the character string "LOT-iαB-" in the lot number setting area which has been output and combined in advance. (Step P6). The result of the character string combination is “LOT-aαB-99”, which is stored in the lot number setting area.

Next, the record of the element number 8 (serial number) of the lot number system table 10 is acquired by the issuing number main processing unit 13, and the acquisition unit column of the acquisition information column of the lot number system table 10 is referred to to obtain the acquisition unit. Is started (step P4). In this example, since "serial number" is described in the acquisition means column, the serial number acquisition means 19
Is started, and a character string is obtained from the item name of the table described in the reference item information column of the reference character information column of the lot number system table 10 (step P10).

In this example, since “manufacturing line management” is described in the table name column of the reference item information column and “latest serial number” is described in the item name column, the latest serial number of the manufacturing line management table 4 is stored. Column is referred, but since the latest serial number is described in plurals, "Latest serial number"
Can not be identified. In this case, the description of the reference item specifying information column of the lot number system table 10 is used to specify the product type.

In this example, the "specified item 1" column in the specified item name column indicates "manufacturing line" (this indicates "manufacturing line" in the manufacturing line management table item), and the "specified information 1" specified material column in the specified material column. "Parameter management" in the table name column,
The "Production line" is described in the item name column of the specific material column of the specific information 1 column, and "Product name" is entered in the specified item name column of the specific information column 2 (this is "Product line" in the production line management table item). Name), "parameter management" in the table name column of the specific material column of the specific information 2 column, and "product name" in the item name column of the specific material column of the specific information 2 column. Based on this information, the parameter management table 14 and the production line management table 4 are combined, and the items “production line” and “product name” of both tables become a combination key. Is specified.

Therefore, in this case, “A” in the production line name column of the parameter management table 14 and “AAAA” in the product name column of the parameter management table 14 are information on the connection source of the production line management table. .

Based on the above information, when the production line management table 4 is combined and searched, the production line in the production line management table 4 is "A" and the product name is "AAA".
The latest serial number "20" in the column labeled "A" is obtained. Add “1” to this “20” to get the “latest serial number”
Is updated, and the shortage of the number of digits
0 ”to obtain“ 0021 ”. The character string combining means 21 combines the character string "LOT-iαB-99" in the lot number setting area, which is output and combined beforehand, with "0021" output from the system date and time acquiring means 18. (Step P6). The character string combination result is “LOT-aαB-990021”, which is stored in the lot number setting area.

The numbering main processing means 13 inputs the character string combination result “LOT-αB-990021” in the lot number setting area output from the character string combination means 21,
The lot number is described in the lot number system table 10 according to the character attribute and is supplied to a system such as MES (step P11). FIG. 11 shows a character string combining process of lot numbers in this example.

Here, when the numbering of the lot numbers for one lot is completed, the steps P2 to P2 are performed for the next one lot.
P11 is executed, and thereafter, the parameter management table 14
Steps P2 to P11 are repeatedly executed until the issue is completed for the number of input lots registered in.

When the numbering is completed for the numbering target record registered in the parameter management table 14,
When the numbering target record of the input lot management table 7 which has been completed is deleted by the numbering main processing means 13, and there is an unnumbered numbering target record in the input lot management table 7, The numbered record to be issued is registered in the parameter management table 14, and there is no unassigned record to be issued in the input lot management table 7, so that steps P1 to P11 are repeatedly executed.

As described above, according to the embodiment of the present invention, the lot number system required by the system introduction destination such as the MES is controlled by the operation of the display terminal 3 or the external system 8.
, The lot number system definition means 11 defines the lot number system table 10 so that the lot number can be automatically issued under the lot number system required by the system introduction destination. That is, according to the embodiment of the present invention, the lot number can be automatically numbered in a general-purpose manner. In consideration of the lot number system, there is no need to develop a mechanism for numbering according to the system, and the development cost of the lot number automatic numbering function can be reduced.

For example, when the lot number for the record in FIG. 10 is issued, it is understood that the lot number having a different serial number should be issued 50 times for the product name "AAAAA". In the element numbers of the lot number system table 10, information acquisition on the element numbers 1 to 7 may be performed only when the first lot number for the product name “AAAAA” is generated, and need not be performed every 50 lots. . That is, when the first lot number is generated, a process of acquiring information on the element numbers 1 to 8 is executed, and the acquired information of the element numbers 1 to 7 is expanded into a memory.
At the time of generating the first lot number, the process of acquiring information is executed only for the element number 8, and for the information regarding the element numbers 1 to 7, the information acquired at the time of generating the first lot number is used (developed in the memory). Then, the third to 50th lot numbers may be generated in the same manner, and in such a case, the lot number generation is speeded up. be able to.
