  The present invention relates to a label printing apparatus and a label printing method for printing a label, and more particularly to a label printing apparatus and a label printing method for extracting information contained in a barcode and printing the extracted information on a label.

  In recent years, the “Special Measures for Information Management and Transmission for Cattle Individual Identification Numbers”, the so-called “Beef Traceability Act” has been issued, and “containers”, “packaging”, “store appearances” for each specific beef. It is obliged to clearly display the individual identification number in any of the “easy places”. Therefore, when the received carcass or block meat is divided and sold at the store, a label on which the individual identification number is printed is attached to each sales unit such as packed meat. In order to print the individual identification number on the label, the individual identification number may be manually input, but the barcode (EAN-128) of the physical distribution label affixed to the carcass or block meat at the time of arrival is scanned. The label printing apparatus is used that reads the individual identification number and extracts the individual identification number, and then prints the extracted individual identification number on a label such as a product label.

  EAN-128, a bar code established by the EAN Association, an international standardization organization, encodes a 2- to 4-digit application identifier (hereinafter referred to as AI) encoded before the data, and data following the AI. Attributes (meaning, data type, number of digits) are defined in advance. The individual identification number is assigned to AI (251) and is defined as a 10-digit number string.

  Therefore, the conventional label printing apparatus reads the barcode (EAN-128) of the physical distribution label with a scanner, extracts AI (251) from the read barcode data (see, for example, Patent Document 1), and AI (251). 10 digits following are extracted as individual identification numbers.

However, when the individual identification number (10 digits) is encoded in the barcode (EAN-128) of the physical distribution label, it is stipulated that AI (251) is used, but the position of AI (251), AI The position of the individual identification number (10 digits) following (251) is not defined, and different operations are performed for each industry unit or group unit. Accordingly, there is a problem that an erroneous individual identification number is extracted only by extracting a numeric string (251) from barcode data and extracting 10 digits following the numeric string (251) as in the prior art. It was.

It is a figure which shows the example of AI table memorize | stored in the AI table memory | storage part shown in FIG.

  The label printing apparatus according to the present embodiment extracts an individual identification number from a barcode (EAN-128) of a distribution label affixed to a received commodity, that is, a carcass or a block meat that has been received, and the extracted individual identification number is obtained. 1 is a device for printing on a label. Referring to FIG. 1, a scanner 2, an AI table storage unit 3, a table management unit 4, a data analysis unit 5, an input unit 6, a print data creation unit 7, and a print Part 8 and output part 9. The label on which the individual identification number is printed is called a succession (relay) label, and is attached to each sales unit such as packed meat.

  The scanner 2 is barcode data acquisition means for acquiring barcode data by reading a barcode (EAN-128) of a physical distribution label affixed to a received carcass or block meat. The acquired barcode data is data Output to the analysis unit 5.

  In the barcode (EAN-128) of the physical distribution label read by the scanner 2, the position of the AI (251) indicating the individual identification number is not defined, and the AI (251) is the head as shown in FIG. And those with AI (251) at the end, as shown in FIG. 2 (b). Also, the position of the individual identification number (10 digits) following AI (251) is not defined, and as shown in FIGS. 2 (a) and 2 (b), the individual identification number immediately follows AI (251). As shown in FIG. 2C, there are those having an individual identification number after “0” after AI (251).

  The AI table storage unit 3 is a storage unit that stores an AI table indicating AI information. Referring to FIG. 3, the AI table refers to “AI digit number” indicating the number of registered AI digits, “Registered AI” indicating the registered AI digit string, and whether the data has a variable length. It consists of a “variable length flag” that indicates whether the length is fixed, a “maximum number of digits” that indicates the maximum number of digits of data, and an “AI type” that indicates the type (data type) of the registered AI. Even if the “AI type” is the same, different “registration AIs” can be registered in the AI table. In this embodiment, a plurality of “registration AIs” representing individual identification numbers are registered. In the example of the AI table shown in FIG. 3, AI (2510) and AI (2511) including a numeric string (251) are registered as “Registered AI” in addition to AI (251) representing the individual identification number. .

  The table management unit 4 is a table management unit that manages the AI table stored in the AI table storage unit 3, and an output item selected and input from the input unit 6 is set.

  The data analysis unit 5 analyzes the barcode data input from the scanner 2 to extract the output item data set in the table management unit 4, and outputs the extracted output item data to the print data creation unit 7. At the same time, if the output item data set in the table management unit 4 cannot be extracted from the barcode data input from the scanner 2, an error signal is output to the output unit 9.

  The input unit 6 is an input unit such as a keyboard, and receives a selection input of an output item to be printed on a label and inputs a new “registration AI” to the AI table stored in the AI table storage unit 3. The correction input and deletion input of “Registered AI” registered in the AI table are accepted.

  When all the data of the output items set by the selection input from the input unit 6 are all input from the data analysis unit 5, the print data creation unit 7 includes the data of the output items input from the data analysis unit 5. Print data is created, and the created print data is output to the printing unit 8.

  The printing unit 8 is a printing unit that prints an output item selected and input by the input unit 6 on a label based on the printing data input from the printing data creation unit 7, and includes, for example, a thermal head and a platen roller. A thermal printing mechanism that performs printing by sandwiching and transporting a label between the thermal head and the platen roller can be used.

  The output unit 9 is an output unit that outputs an error based on an error signal input from the data analysis unit 5. For example, a display unit such as a liquid crystal display that displays an error output as a character string, or an error output as a voice Audio output means for outputting can be used.

Next, the operation of the present embodiment will be described in detail with reference to FIG.
FIG. 4 is a flowchart for explaining the operation of the embodiment of the label printing apparatus according to the present invention.

  First, output items (individual identification number, lot number, date of manufacture, etc.) to be printed on the inherited label are selected and input from the input unit 6 (step A1). The table management unit 4 and the print data creation unit 7 The output item selected and input from 6 is set.

  Next, the barcode (EAN-128) of the physical distribution label affixed to the carcass or block meat received by the scanner 2 is read to obtain barcode data (step A2). The acquired barcode data is input to the data analysis unit 5, and output items are extracted from the barcode data by the data analysis unit 5.

  In the extraction of output items from the barcode data by the data analysis unit 5, first, the pointer is set to the first FNC 1 (step A3), and the AI table stored in the AI table storage unit 3 via the table management unit 4 is stored. By referring, it is determined whether or not there is an AI in the 4-digit part from the pointer (step A4). Note that FNC1 is a delimiter used for a bar code (EAN-128), and is always encoded immediately after the start code. When AI is variable-length data, it is encoded after that.

  If there is no AI in the 4-digit part from the pointer in step A4, the process goes to step A20, which will be described later. If there is an AI in the 4-digit part from the pointer in step A4, the data analysis unit 5 It is determined whether or not AI (hereinafter referred to as “extracted AI”) is an output item set in the table management unit 4 (step A5).

  If the extracted AI is an output item in step A5, it is determined whether the extracted AI is variable data by referring to the AI table stored in the AI table storage unit 3 via the table management unit 4. Judgment is made (step A6), and if the extracted AI is variable data, data for the number of variable digits is extracted, that is, data is extracted to the end of the next FNC1 or barcode data (step A7).

  Next, the data analysis unit 5 determines whether or not the extraction AI is an individual identification number (step A8), and if the extraction AI is an individual identification number, extracts 10-digit data following the extraction AI. Then, a check digit of 1 to 9 digits is calculated, and it is determined whether or not the check digit is approved by collating with 10 digits (step A9).

  If the check digit is not approved in step A9, the process proceeds to step A20, which will be described later. If the check digit is approved in step A9, the data analysis unit 5 uses the 10-digit data in which the check digit is approved as an individual. The identification number is output to the print data creation unit 7 (step A10), and the pointer is updated to the next FNC 1 (step A11). When the extracted AI is an individual identification number, that is, AI (251), a plurality of registered AIs including a numeric string 251 are registered in the AI table as shown in FIG. May correspond to the extracted AI. In this case, the check digit is confirmed for each of the plurality of registered AIs, and 10-digit data for which the check digit is approved is output to the print data creation unit 7 as an individual identification number.

  For example, in the barcode shown in FIG. 2A, when the individual identification number is set as an output item, the registration AI (251) corresponds to the registration AI (2510), and the registration AI (251). In this case, the check digit of “03418040667” which is the correct individual identification number is confirmed and approved in step A9. However, in the case of registration AI (2510), “3418040671” erroneous in step A9 is confirmed. Since the check digit is confirmed and not approved, only the correct individual identification number for which the check digit is approved in step A9 is output to the print data creation unit 7.

  For example, in the barcode shown in FIG. 2B, when the individual identification number is set as an output item, the registration AI (251) corresponds to the registration AI (2510), and the registration AI (251). In this case, the check digit of “03418040667”, which is the correct individual identification number, is approved in step A9. However, in the case of registered AI (2510), the check digit of “341804067” is approved in step A9. Therefore, only the correct individual identification number whose check digit is approved in step A9 is output to the print data creation unit 7.

  For example, in the barcode shown in FIG. 2C, when the individual identification number is set as an output item, the registration AI (251) corresponds to the registration AI (2510), and the registration AI (251). In this case, the check digit of “0034180406” is not approved in step A9. However, in the case of registration AI (2510), the check digit of “03418040667” which is the correct individual identification number is approved in step A9. Therefore, only the correct individual identification number whose check digit is approved in step A9 is output to the print data creation unit 7.

  If the extracted AI is not the individual identification number in step A8, the data analyzing unit 5 outputs the data for the variable number of digits following the extracted AI to the print data creating unit 7 (step A12), and sends it to the next FNC1. The pointer is updated (step A11).

  Further, if the extraction AI is not variable data in step A6, the data analysis unit 5 extracts data for a fixed number of digits (step A13) and outputs the extracted data to the print data creation unit 7 (step A14). ) The pointer is updated by a fixed number of digits (step A15).

  Furthermore, if the extracted AI is not an output item in step A5, whether the extracted AI is variable data by referring to the AI table stored in the AI table storage unit 3 via the table management unit 4 is determined. Is determined (step A16).

  If the extracted AI is variable data in step A16, the process proceeds to step A11 described above, and the pointer is updated to the next FNC1, and if the extracted AI is not variable data in step A16, the process proceeds to step A15 described above. Update the pointer by a fixed number of digits.

  Next, the data analysis unit 5 determines whether or not the data of all the output items set in the table management unit 4 and the print data creation unit 7 have been extracted (step A17), and the respective data of the output items. Is not extracted, it is determined whether or not there is subsequent data in the barcode data (step A18). If there is subsequent data, the process returns to step A4, and the data of each output item is hereinafter referred to. Steps A4 to A18 are repeated until all are extracted.

  When the data of all the output items set in the table management unit 4 and the print data creation unit 7 are extracted in step A17, the print data creation unit 7 stores the data of all the set output items, respectively. The print data creation unit 7 creates print data including the input output item data and outputs the print data to the print unit 8, and the print unit 8 prints the output item data on the label (step A19). ) If the output item includes an individual identification number, it is an inherited (relay) label.

  Also, when there is no AI in the 4-digit part from the pointer at step A4, when there is no extracted data whose check digit is OK at step A9, and when there is no subsequent data at step A18, it is acquired by the scanner 2 Since it is determined that there is an output item that cannot be extracted from the barcode data, the data analysis unit 5 causes the output unit 9 to output an error (step A20). If there is no AI in the 4-digit part from the pointer in step A4, it is determined that the barcode data acquired in step A2 does not correspond to EAN128, and the data analysis unit 5 is connected to the output unit 9 by the scanner 2. An error message indicating that the read barcode is not a correct EAN128 barcode is output. If there is no extracted data in which the check digit is OK in step A9, it is determined that the correct individual identification number could not be extracted from the bar code data acquired in step A2. The unit 9 outputs an error message indicating that the barcode read by the scanner 2 does not contain the correct individual identification number. Furthermore, if there is no subsequent data in step A18, it is determined that there are output items that cannot be extracted from the barcode data acquired by the scanner 2 among the output items selected and input in step A1, and therefore the data analysis unit 5 Outputs an error message indicating that there are output items that cannot be extracted from the barcode read by the scanner 2 in the output unit 9.

  As described above, according to the present embodiment, an AI table in which a plurality of numeric strings including an application identifier indicating that the subsequent data is an individual identification number is registered in the AI table storage unit 3. The data analysis unit 5 refers to the AI table stored in the AI table storage unit 3 to extract each of a plurality of number sequences registered in the AI table from the barcode data, and follows the extracted number sequence. Each check digit of the data is confirmed, and the data for which the check digit is approved is output to the print data creation unit 7 as an individual identification number. The print data creation unit 7 creates print data including the individual identification number, and the print unit 8 is configured to print the individual identification number on the label based on the print data created by the print data creation unit 7. In addition, in the distribution label bar code, even when there is variation in the position of the application identifier indicating that the subsequent data is an individual identification number or the position of the individual identification number following the application identifier indicating that it is an individual identification number Thus, the correct individual identification number can be extracted, and the extracted correct individual identification number can be printed on the label.
