The first product information regarding the product includes, for example, a product ID, a product name (product item), a raw material name, a price, a weight, and the like, as will be described later. In addition, the storage unit 91 stores and stores the inspection results of the product label inspection unit 96B, which will be described later.

The control unit 95 is an electronic control unit including a CPU, ROM, RAM, and the like. The control unit 95 controls various operations on the management server 9. The control unit 95 can be configured as software in which a program stored in the ROM is loaded into the RAM and executed by the CPU, for example. The control unit 95 may be configured as hardware such as an electronic circuit. In the control unit 95, the hardware such as the CPU, RAM and ROM, and the software such as the program cooperate with each other to acquire the text information extraction unit 96A, the product label inspection unit 96B, and the first product information as shown below. A unit 96C, a second product information acquisition unit 96D, and a ledger inspection unit 96E are formed.

The text information extraction unit 96A extracts the first text information from the captured image of the imaging unit 11. Specifically, the text information extraction unit 96A performs OCR (Optical Character Recognition / Reader) analysis on the image of the sample label 61, and obtains the first text information included in the image of the sample label 61. Extract. At the same time, the text information extraction unit 96A extracts the second text information from the captured image of the imaging unit 11. Specifically, the text information extraction unit 96A performs OCR analysis on the image of the product label 63 and extracts the second text information included in the image of the product label 63. At the time of the secondary check, the text information extraction unit 96A identifies the image of the sample label 61 and the image of the product label 63 from the entire image of the label ledger 50. The text information is text-only information and does not include information on font type, size, label design, design, pattern, pattern, and the like. The text information extraction method and identification method are not particularly limited, and various known methods can be used.

For example, the text information extraction unit 96A extracts the product name and its position on the sample label 61 and the product name and its position on the product label 63. For example, the text information extraction unit 96A extracts the product code and its position on the sample label 61 and the product code and its position on the product label 63. For example, the text information extraction unit 96A extracts the raw material name (allergic material name) and its position on the sample label 61, and the raw material name and its position on the product label 63. The position information of the sample label 61 and the product label 63 can be extracted as coordinate information based on, for example, a reference position such as the center of the label.

The product label inspection unit 96B inspects the correctness of the product label 63 based on the comparison between the first text information and the second text information extracted by the text information extraction unit 96A. The product label inspection unit 96B determines that the product label 63 is correct when the first text information and the second text information match. The product label inspection unit 96B determines that the product label 63 is incorrect when the first text information and the second text information do not match. The product label inspection unit 96B stores and stores the inspection result in the storage unit 91.

For example, the product label inspection unit 96B inspects whether or not the product name and its position on the sample label 61 and the product name and its position on the product label 63 match. In other words, the product label inspection unit 96B determines whether or not the text relating to the product name existing at the specific position (for example, the center) of the sample label 61 matches the text relating to the product name at the specific position of the product label 63. Inspect whether or not.

For example, the product label inspection unit 96B inspects whether or not the product code and its position on the sample label 61 and the product code and its position on the product label 63 match. In other words, the product label inspection unit 96B inspects whether or not the text related to the product code at the specific position of the sample label 61 matches the text related to the product code at the specific position on the product label 63.

For example, the product label inspection unit 96B extracts whether or not the raw material name (allergic material name) and its position on the sample label 61 and the raw material name and its position on the product label 63 match. In other words, the product label inspection unit 96B inspects whether or not the text related to the raw material name at the specific position of the sample label 61 matches the text related to the raw material name at the specific position on the product label 63.

The text match in this embodiment includes an exact match. The text match in this embodiment may include partial match, prefix match and suffix match. Since there is a possibility that character recognition error may occur when extracting text information, a mismatch of about several characters (for example, a predetermined number of 1 or 2 characters) may be allowed.

The first product information acquisition unit 96C acquires the barcode 51 of the label ledger 50 from the captured image of the imaging unit 11, and acquires the first product information associated with the barcode 51 from the storage unit 91. The first product information is, for example, a product ID, a product name (product item), a raw material name, a price, a weight, and the like. The first product information is text information. The second product information acquisition unit 96D acquires the second product information, which is information about the product printed on the label ledger 50, from the captured image of the image pickup unit 11. The second product information is, for example, a product name, a raw material name, or the like, like the first product information. The second product information is information included in the sample label 61 of the label ledger 50. The second product information acquisition unit 96D performs OCR analysis on the image of the sample label 61, and extracts and acquires the second product information as text information included in the image of the sample label 61.

The ledger inspection unit 96E inspects the correctness of the label ledger 50 itself, not the product label 63. Specifically, the ledger inspection unit 96E compares the first product information acquired from the storage unit 91 with the second product information acquired from the image captured by the imaging unit 11, and the label ledger 50 is correct. Inspect if there is. The ledger inspection unit 96E determines that the label ledger 50 is correct when the first product information and the second product information match, but when the first product information and the second product information do not match, the label ledger 50 determines that the label ledger 50 is correct. It is determined that the product label 63 is incorrect. That is, when the ledger inspection unit 96E matches the first product information stored in association with the barcode 51 with the second product information acquired from the sample label 61 printed on the label ledger 50. In addition, it is determined that the label ledger 50 is correct.

The communication unit 97 transmits / receives information to / from the terminal device 3. The communication unit 97 transmits the correctness of the product label 63 inspected by the product label inspection unit 96B to the terminal device 3. The communication unit 97 transmits the correctness of the label ledger 50 inspected by the ledger inspection unit 96E to the terminal device 3. The communication unit 97 receives the captured image of the image pickup unit 11 from the terminal device 3. In the inspection device 1 as described above, when the inspection result of the product label inspection unit 96B is that the product label 63 is incorrect, the control unit 95 transmits error information to the label issuing unit 30 via the communication unit 97. To do.

Next, an example of the operation of the inspection device 1 will be described with reference to FIG.

When inspecting the correctness of the product label 63 of the label ledger 50 as a primary check, the operator first installs the terminal device 3 on the gantry 5 (see FIG. 5) so that the label ledger 50 can be imaged. The operator operates the display operation unit 13 of the terminal device 3 and images the label ledger 50 by the image pickup unit 11 (step S1). In step S1, for example, the sample label 61 is imaged according to the guide, and an image showing the sample label 61 is acquired. In step S1, for example, the product label 63 is imaged according to the guide, and an image showing the product label 63 is acquired. The product label 63 is at least one of the labels (1) to (5) above.

The captured image acquired by the imaging unit 11 is transmitted to the management server 9 by the communication unit 17 (step S2). The text information extraction unit 96A of the management server 9 extracts text information from the captured image transmitted from the terminal device 3 (step S3). In step S3, the image of the sample label 61 is subjected to OCR analysis, and the first text information of the sample label 61 is extracted. In step S3, the image of the product label 63 is subjected to OCR analysis to extract the second text information.

The product label inspection unit 96B of the management server 9 determines whether or not the extracted first text information and the second text information match (step S7). If YES in step S7, the product label inspection unit 96B determines that the product label 63 is correct in the inspection result (step S8). The communication unit 97 of the management server 9 transmits the inspection result of the above step S8 to the terminal device 3 (step S10). If NO in step S7, the product label inspection unit 96B determines that the product label 63 is incorrect in the inspection result (step S11). The communication unit 97 of the management server 9 transmits the inspection result of the above step S8 to the terminal device 3 and also transmits the error information to the label issuing unit 30 (step S11). Then, the display operation unit 13 of the terminal device 3 notifies the inspection result (step S12). The label issuing unit 30 that has received the error information stops printing items corresponding to, for example, the expiration date of the table label 63A. The label issuing unit 30 that has received the error information may stop printing the back label 63B.

Incidentally, when inspecting the correctness of the product label 63 of the label ledger 50 as a secondary check, in step S1, the administrator takes an image of the entire label ledger 50 by the imaging unit 11. In step S3, the sample label 61 and the product label 63 are recognized from the entire image of the label ledger 50, and the first text information and the second text information are extracted.

As described above, since the inspection device 1 collates the first text information with the second text information, it is possible to inspect the correctness of the product label 63 regardless of the type of the character font of the product label 63. Therefore, it is possible to accurately inspect the correctness of the product label 63. This effect is particularly effective because there are many cases where only the design (including font change) of the product label 63 on which the product name or the like is pre-printed is changed without changing the product name. In the inspection device 1, when inspecting the product label 63, even if the product label 63 is a new product, the work does not increase (does not change).

The inspection device 1 includes a display operation unit 13 as a notification unit for notifying the inspection result of the product label inspection unit 96B. As a result, for example, the inspection result of the product label inspection unit 96B can be notified to the worker or the like.

In the inspection device 1, the imaging unit 11 images the label ledger 50 as a medium. The label ledger 50 includes a portion 53 on which the first text information is printed and a portion 55 to which the product label 63 to be attached to the product according to the work stage is attached. The product label 63 is at least one of the labels (1) to (5) above. Thereby, for example, a mistake in labeling by the label sticking device 100 can be effectively detected. Further, for example, when the label is replaced in the label affixing device 100, it can be estimated that there is no mistake in the replacement.

In the inspection device 1, the portion 53 on which the first text information is printed in the label ledger 50 is the portion 53 on which the sample label 61 is printed. The sample label 61 is a printed image of the product label 63 as it is. In this case, it is possible to extract the first text information in the same manner as the extraction of the second text information. If the sample label 61 is the same as the image of the product label 63, it is possible to suppress the inclusion of unnecessary information when extracting the first text information from the sample label 61. The color, size, resolution, and the like of the product label 63 and the sample label 61 may be slightly different (for example, an error due to a printer or the like to be printed).

In the inspection device 1, the text information extraction unit 96A extracts the product name and its position on the sample label 61 and the product name and its position on the product label 63. The product label inspection unit 96B inspects whether or not the product name and its position on the sample label 61 and the product name and its position on the product label 63 match. In this case, it is possible to prevent the sample label 61 and the product label 63 from collating the product names to be collated (for example, collating another product name existing at a different position on the sample label 61 and the product label 63). Then, the correctness of the product label 63 can be inspected.

In the inspection device 1, the text information extraction unit 96A extracts the product code and its position on the sample label 61 and the product code and its position on the product label 63. The product label inspection unit 96B inspects whether or not the product code and its position on the sample label 61 and the product code and its position on the product label 63 match. In this case, it is possible to prevent the sample label 61 and the product label 63 from collating the product codes to be collated (for example, collating another product code existing at a different position on the sample label 61 and the product label 63). Then, the correctness of the product label 63 can be inspected.

In the inspection device 1, for example, in the primary check, the imaging unit 11 pinpoints the sample label 61 of the label ledger 50 and pinpoints each product label 63 of the label ledger 50. In this case, it is possible to eliminate the need for image processing for extracting the parts corresponding to the sample label 61 and each product label 63 from the image of the imaging unit 11. The primary check may be performed each time the product label 63 is attached to the label ledger, or may be performed after the product production is completed.

In the inspection device 1, for example, in the secondary check, the image pickup unit 11 takes an image of the entire label ledger 50 at a time and acquires the entire image of the label ledger 50. In this case, it is possible to reduce the labor involved in the work related to imaging. The work can be simplified. In the secondary check, since the label ledger 50 in which all the product labels 63 are already attached is determined, it may be imaged (scanned) at once by a separate scanner or the like.

The inspection device 1 acquires the barcode 51 printed on the label ledger 50 from the storage unit 91 that associates and stores the product barcode 51 and the first product information in advance and the image captured by the imaging unit 11. , The first product information acquisition unit 96C that acquires the first product information associated with the barcode 51 from the storage unit 91, and the second product information printed on the label ledger 50 from the image captured by the imaging unit 11. The correctness of the label ledger 50 is compared with the second product information acquisition unit 96D to be acquired, the first product information acquired from the storage unit 91, and the second product information acquired from the image captured by the imaging unit 11. It is equipped with a ledger inspection unit 96E for inspecting. In this case, it is possible to determine whether the label ledger 50 is correct or not.

The label affixing device 100 includes a display input panel 80 that accepts an operation for designating a product, a label issuing unit 30 that prints print information of the designated product on a label and issues a product label 63, and a issued product label 63. A label affixing portion 40 for affixing the above to a product and an inspection device 1 are provided. The inspection device 1 transmits error information to the label issuing unit 30 when the inspection result of the product label inspection unit 96B is that the product label 63 is incorrect. Since the label affixing device 100 is also provided with the inspection device 1, it is possible to accurately inspect the correctness of the product label 63. Further, the label issuing unit 30 can suspend the printing or issuing based on the error information, and as a result, it is possible to reduce the number of products to which the mismatched product label 63 is attached.

In the inspection device 1, the imaging unit 11 images the label ledger 50. As a result, the correctness of the product label 63 can be inspected at the site where the correctness of the product label 63 is inspected using such a label ledger 50.

As shown in FIG. 7, the text information extraction unit 96A may preferentially extract the text around the specific text by using the specific text (black square in the figure) T0. In the example in the figure, by attaching the specific text T0 to the front of the text indicating the work stage of the product label 63, the work stage can be preferentially extracted. As a result, the text information can be identified with high accuracy. The specific text T0 is not limited to the characters, and may be configured to include one or a plurality of symbols in place of or in addition to the characters.

FIG. 8 is a diagram showing an example of a list of ledger information to be displayed. FIG. 9 is a diagram showing an example of a label inspection result list to be displayed. FIG. 10 is a diagram showing an example of details of the label inspection result to be displayed. The terminal device 3 reads the inspection result of the label ledger 50 stored in the storage unit 91 of the management server 9, for example, in response to the operation of the operator or the administrator on the display operation unit 13 or other display input units. The inspection result can be appropriately displayed on the display operation unit 13 or other display input units. Examples of the display input unit other than the display operation unit 13 include a touch panel (not shown) of a computer arranged in the management room as the terminal device 3.

As illustrated in FIG. 8, a list of information related to a plurality of label ledgers 50 can be displayed as a ledger information list on the display operation unit 13 or other display input units. In the illustrated example, the information of each label ledger 50 in the ledger information list includes the operation start date and time, the line information of the line that manufactures the product, the product code, the product name, and the operating state. In the display operation unit 13 or other display input units, by designating the display period and touching the display button, only the information of the label ledger 50 whose operation start date and time exists in the display period can be displayed. .. In the display operation unit 13 or other display input units, the result list of the touched label ledger 50 can be displayed by touching the button of the result list in the information of each label ledger 50.

As illustrated in FIG. 9, a list of inspection results of a plurality of product labels 63 in the label ledger 50 can be displayed as a label inspection result list on the display operation unit 13 or other display input units. In the illustrated example, the inspection results of each product label 63 in the label inspection result list are the analysis date and time (inspection date and time), the product code, the product name, the analysis label (work stage), the inspection result, and the person in charge ID (person in charge). Identification number) is included. In the display operation unit 13 or other display input units, by touching the detail button in each inspection result, the details of the touched inspection result can be displayed.

As illustrated in FIG. 10, the details of the inspection result of the product label 63 can be displayed as the label inspection result details on the display operation unit 13 or other display input units. The label inspection result details include the analysis date and time (inspection date and time), the product code, the product name, the analysis label (work stage), the inspection result, the person in charge ID (person in charge identification number), and the person in charge name. In addition, the label inspection result details include the target name, the correct answer value, and the inspection result. The target name indicates whether the inspection target is the front label 63A or the back label 63B, and what text is the text to be inspected. For example, as the target name, when the product name of the table label 63A is the target of inspection, it is indicated as table product name analysis. The correct answer value indicates what the specific characters of the text are when the test result is correct. The test result indicates whether or not the test result is OK.

[Second Embodiment]
Next, the second embodiment will be described. In the description of the present embodiment, the points different from those of the first embodiment will be described, and the overlapping configuration will be omitted.

FIG. 11 is a block diagram showing the configuration of the inspection device 201 of the second embodiment. The inspection device 201 is different from the inspection device 1 (FIG. 4) in that the control unit 95 further includes an identification information identification unit 95A, an image information acquisition unit 95B, a first extraction unit 95C, and a second extraction unit 95D.

The identification information identification unit 95A identifies the identification information of the product related to production. In the present embodiment, the identification information identification unit 95A identifies the product identification information from the captured image of the label ledger 50 transmitted from the terminal device 3. More specifically, the identification information identification unit 95A identifies the product identification information as text information (code) from the image of the barcode 51 included in the captured image.

The image information acquisition unit 95B acquires the image information of the product label 63 from the captured image of the label ledger 50 transmitted from the terminal device 3. The first extraction unit 95C extracts the product information stored in association with the product identification information specified by the identification information identification unit 95A from the storage unit 91. In the present embodiment, the first extraction unit 95C extracts the product name (product item) stored in association with the product identification information specified by the identification information identification unit 95A from the storage unit 91.

The second extraction unit 95D extracts the character string included in the image information acquired by the image information acquisition unit 95B as text information by OCR analysis. Here, various information is printed on the front label 61A and the back label 61B. When extracting such information, the second extraction unit 95D cannot always obtain the information separately for each item. Therefore, the second extraction unit 95D may also extract information other than the desired items. For example, when the second extraction unit 95D extracts the product name from the table label 61A, the second extraction unit 95D together with the product name is a character string, a price, or an expiration date for calling attention such as "Please consume by the expiration date". In some cases, the character strings such as are also extracted.

In some cases, the second extraction unit 95D can be adjusted to extract only desired items by adjusting and limiting the extraction position by software or hardware. For example, the extraction position may be extracted based on the coordinate information, or may be extracted based on the relative relationship with the positions of other parts. Further, the extraction may be performed by providing a mark or the like for fixing the arrangement position of the label ledger 50 with respect to the installation position of the image pickup unit 11 (tablet terminal). This also applies to the extraction by the text information extraction unit 96A described above.

In addition to the inspection of the correctness of the product label 63 in the first embodiment described above, the product label inspection unit 96B inspects the correctness of the product label 63, for example, as follows. That is, the product label inspection unit 96B is based on the degree of matching between the character string as the text information extracted by the first extraction unit 95C and the character string as the text information extracted by the second extraction unit 95D. The correctness of the label 63 can be determined. Specifically, the product label inspection unit 96B labels when the character string extracted by the first extraction unit 95C is included in the character string extracted by the second extraction unit 95D (partially matches). When it is determined that the product label 63 attached to the ledger 50 is correct, and the character string extracted by the first extraction unit 95C is not included (does not match) in the character string extracted by the second extraction unit 95D. , It is determined that the product label 63 attached to the label ledger 50 is incorrect (wrong). Here, the partial match of both character strings is used as the criterion for determining the correctness of the product label 63, but the exact match of both character strings may be used as the criterion for determining the correctness.

Hereinafter, an example of the operation of the inspection device 201 will be described with reference to FIG.

The operator operates the display operation unit 13 of the terminal device 3 to cause the image pickup unit 11 to take an image of the label ledger 50. As a result, the image pickup unit 11 acquires the captured image of the label ledger 50 (step S101). The captured image of the label ledger 50 acquired by the imaging unit 11 is transmitted to the management server 9 by the communication unit 17 (step S102).

The identification information identification unit 95A of the management server 9 identifies the product identification information from the captured image of the barcode 51 included in the captured image of the label ledger 50 transmitted from the terminal device 3 (step S103). Here, it will be described below assuming that the product identification information specified by the identification information identification unit 95A is associated with the product name “curry bread” in the storage unit 91.

Further, the image information acquisition unit 95B of the management server 9 acquires the image information of the product label 63 from the captured image of the label ledger 50 transmitted from the terminal device 3 (step S104). Here, assuming that the image information acquisition unit 95B has acquired the images of the front label 63A and the back label 63B printed with the product name "curry bread", the following description will be given.

Next, the first extraction unit 95C of the management server 9 extracts the product name stored in association with the product identification information specified by the identification information identification unit 95A from the storage unit 91 as text information (step S105). Here, it is assumed that the first extraction unit 95C extracts the product name “curry bread” stored in association with the product identification information in the storage unit 91. The second extraction unit 95D of the management server 9 extracts the character strings included in the image information of the front label 63A and the back label 63B acquired by the image information acquisition unit 95B (step S106). Here, it is assumed that the second extraction unit 95D extracts the character string "curry bread ¥ 110 (tax included ¥ 118)" including "curry bread" as text information.

The product label inspection unit 96B of the management server 9 determines whether or not the character string acquired in step S105 is included in the character string acquired in step S106 (step S107). Here, the product label inspection unit 96B determines that the product label 63 is correct when the character string acquired in step S105 is included in the character string acquired in step S106 (step S108). If the character string acquired in step S105 is not included in the character string acquired in step S106, it is determined that the product label 63 is incorrect (step S109). In addition, "included in the character string" means that one character string is segmented into words by morphological analysis or the like, and then each word is included in the other character string.

Here, since the character string "curry bread" acquired in step S105 is included in the character string "curry bread ¥ 110 (tax included ¥ 118)" acquired in step S106, it is determined that the product label 63 is correct. To do. The product label inspection unit 96B determines whether or not each of the front label 63A and the back label 63B is a correct label. On the other hand, for example, when the character string acquired in step S106 is "melon bread ¥ 110 (tax included ¥ 118)", the character string "curry bread" acquired in step S105 is not included in it. Therefore, the product label inspection unit 96B determines that the product label 63 is incorrect.

The communication unit 97 of the management server 9 transmits the inspection results in steps S108 and S109 to the terminal device 3 (step S110). The inspection result transmitted by the management server 9 is received by the communication unit 17 of the terminal device 3. The control unit 15 of the terminal device 3 notifies the received inspection result by the display operation unit 13 (step S111).

Returning to FIG. 11, in the inspection device 201, the control unit 95 further includes a third extraction unit 95E and a notification unit 95G. The third extraction unit 95E extracts the product name including all the character strings included in the product name extracted by the first extraction unit 95C from the storage unit 91. In the storage unit 91, other product identification information is associated with the product name extracted in this way. For example, when the character string included in the product name extracted by the first extraction unit 95C is "curry bread" and the storage unit 91 stores "dry curry bread" and "super spicy curry bread" as product names. , Third extraction unit 95E extracts "dry curry bread" and "super spicy curry bread" from the storage unit 91.

The third extraction unit 95E extracts the product name extracted by the first extraction unit 95C instead of extracting the product name including all the character strings included in the product name extracted by the first extraction unit 95C from the storage unit 91. A product name having a character string whose editing distance from the name character string is within a predetermined distance (for example, twice) may be extracted from the storage unit 91. Even in this case, the third extraction unit 95E can extract with another product name similar to the product name extracted by the first extraction unit 95C.

In the product label inspection unit 96B, when the character string of the product name extracted by the third extraction unit 95E is included in the character string of the product name extracted by the second extraction unit 95D, the product label 63 is correct. Judge that it is not a thing. For example, the first extraction unit 95C extracts the product name character string "curry bread" from the storage unit 91 based on the barcode 51, and the second extraction unit 95D extracts the product name character string "dry curry bread ¥ 110 (dry curry bread ¥ 110). Tax-included ¥ 118) ”is extracted. Since the product label inspection unit 96B includes the character string "curry bread" acquired in step S105 in the character string "dry curry bread ¥ 110 (tax included ¥ 118)" acquired in step S106, the product label 63 is temporarily determined to be correct. However, in the product label inspection unit 96B, the character string of the product name "dry curry bread ¥ 110 (¥ 118 including tax)" extracted by the second extraction unit 95D is the character of the product name extracted by the third extraction unit 95E. Since it is also included in the column "dry curry bread", the product label 63 is finally determined to be incorrect.

The notification unit 95G notifies that the product name has been extracted by the third extraction unit 95E. Specifically, when the product name is extracted by the third extraction unit 95E, the notification unit 95G has a product name similar to the product name extracted by the first extraction unit 95C in the display operation unit 13 of the terminal device 3. Indicates that is present in the storage unit 91. The notification unit 95G may display a specific product name extracted by the third extraction unit 95E.

Hereinafter, an example of a determination method of the product label inspection unit 96B will be described with reference to FIG.

The first extraction unit 95C extracts the product name stored in association with the product identification information specified by the identification information identification unit 95A from the storage unit 91. Here, it is assumed that the first extraction unit 95C has acquired the product name “curry bread” from the storage unit 91 (step S121).

The third extraction unit 95E searches the storage unit 91 for whether or not there is another product name containing the "curry bread" extracted by the first extraction unit 95C (step S122). Here, it is assumed that the third extraction unit 95E extracts the product names "dry curry bread" and "super spicy curry bread" from the storage unit 91 (step S123). The product label inspection unit 96B determines whether or not "curry bread" is included in the character string of the product name extracted by the second extraction unit 95D (step S124).

When "curry bread" is not included in the character string of the product name (step S124: YES above), the product label inspection unit 96B determines that the product label 63 is incorrect (wrong) (step). S127). On the other hand, when "curry bread" is included in the character string of the product name (step S124: NO above), the product label inspection unit 96B is the character string of the product name extracted by the second extraction unit 95D. It is determined whether or not "dry curry bread" is contained in the product (step S125).

When "dry curry bread" is included in the character string of the product name (step S125: YES above), the product label inspection unit 96B determines that the product label 63 is incorrect (wrong) (it is incorrect). Step S127). On the other hand, when "dry curry bread" is not included in the character string of the product name (step S125: NO above), the product label inspection unit 96B is the character of the product name extracted by the second extraction unit 95D. It is determined whether or not "super spicy curry bread" is included in the column (step S126).

When "super spicy curry bread" is included in the character string of the product name (step S126: YES above), the product label inspection unit 96B determines that the product label 63 is incorrect (wrong) (it is incorrect). Step S127). On the other hand, when the character string of the product name does not include "super spicy curry bread" (step S126: NO above), the product label inspection unit 96B determines that the product label 63 is correct (there is no mistake). (Step S128).

In the determination process of the product label inspection unit 96B described above, the step S125 and the step S126 can be interchanged. Further, the process of executing the step S125 and the step S126 may be performed before the step S124.

More modified when there is another product name that has a modifying phrase and includes the entire character string, such as "dry curry bread" or "super spicy curry bread" for "curry bread". When the product name is included in the character string extracted by the second extraction unit 95D, the front label 61A (back label 61B) attached to the label ledger 50 corresponds to the product name with more modifications. It can be said that there is a high probability that it is. Therefore, if the character string extracted by the second extraction unit 95D contains a product name longer than the product name including itself extracted by the third extraction unit 95E, the product extracted by the third extraction unit 95E. It may be determined that the product of the name and the front label 61A (back label 61B) attached to the label ledger 50 match (even if the flow is terminated).

As described above, the inspection device 201 also has the same effect as the inspection device 1. Further, the inspection device 201 does not compare the image information of the sample label 61 with the image information of the product label 63, but instead compares the product name as a character string (text information) stored in the storage unit 91 with the product label. The correctness of the product label 63 is determined by comparing it with the product name as a character string (text information) extracted from the image information of 63. As a result, even if the design of the product label 63 is changed, the correctness of the product label 63 can be determined without performing the change work such as replacing the product label 63 to be attached.

In the inspection device 201, the third extraction unit 95E extracts a product name similar to the product name extracted by the first extraction unit 95C, and the product label inspection unit 96B extracts the product extracted by the third extraction unit 95E. When the character string of the name is included in the character string of the product name extracted by the second extraction unit 95D, it is determined that the product label 63 is not correct. That is, the product label inspection unit 96B changes the character string "dry curry bread" or "super spicy curry bread" extracted by the third extraction unit 95E into the character string "dry curry bread" extracted by the second extraction unit 95D. It is determined whether or not it is included. Here, the product label inspection unit 96B determines that the character string "dry curry bread" extracted by the third extraction unit 95E is included in the character string "dry curry bread" extracted by the second extraction unit 95D. , It is determined that the product label 63 acquired by the image information acquisition unit 95B is not correct. As a result, the accuracy of determining correctness in the product label inspection unit 96B can be improved.

[Modification example]
Although one embodiment has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the invention.

(Modification example 1)
The control unit 95 may further include a conversion unit. The conversion unit extracts the product name (predetermined product item) to be compared in the product information stored in association with the identification information specified by the identification information identification unit 95A as text information, and also extracts the extracted text. Convert the information to the first image information (conversion step). The conversion unit may be provided so that the font for converting the extracted text information into the first image information can be selectively set. For example, the conversion unit may select a font of characters included in the second image information, which is the image information of the product label 63 acquired by the image information acquisition unit 95B. The above selection in the conversion unit may be automatically converted from the image information of the product label 63 into the font to be analyzed, or may be selected by the operation of the operator.

The font to be converted (typeface, size, character spacing, character arrangement position, etc.) is stored in, for example, the storage unit 91 of the management server 9 together with the corresponding product identification information. The conversion unit acquires the font to be converted from the management server 9 and converts it according to the product identification information corresponding to the barcode 51 read by the label ledger 50. The conversion unit may acquire the font to be converted from the printer that printed the label.

The product label inspection unit 96B determines the correctness of the product label 63 based on the comparison between the first image information converted by the conversion unit and the second image information acquired by the image information acquisition unit 95B. Specifically, the product label inspection unit 96B determines the correctness of the product label 63 based on the degree of coincidence between the first image information and the second image information. The determination based on the degree of matching referred to here can be executed by using a known comparison method such as a determination based on the matching rate of the image information or a determination based on the matching rate of the feature portion of the image information. Specifically, for example, the product label inspection unit 96B determines whether or not the feature portion of the image included in the first image information including the converted characters is included in the feature portion of the image included in the second image information. Based on this, the correctness of the product label 63 may be determined. Since the second image information includes information other than the character information of the item to be compared, the feature portion of the image included in the first image information becomes the feature portion of the image included in the second image information. It is desirable to configure it so that it is judged by whether or not it is included. Further, the image information (first image information and second image information) referred to here refers to image data composed of models such as JPEG, GIF, PNG, TIFF, BMP, and PDF.

In the first modification, the image information of the sample label 61 and the image information of the product label 63 acquired by the image information acquisition unit 95B are not simply compared, but the product name stored in the storage unit 91 as text information is used. By comparing the first image information created based on the above with the second image information which is the image information of the product label 63, the correctness of the product label 63 is determined. That is, in the modification 1, the reference data for determining the correctness of the product label 63 is the first image information generated based on the text information stored in the storage unit 91. As a result, even if the design of the product label 63 is changed, the correctness of the product label 63 can be determined without performing the change work such as replacing the sample label 61.

Further, in the first modification, when converting the text information to the first image information, the font can be selected so as to match the font of the printed product item, so that the first image information and the second image information can be selected. The comparison with the image information becomes easy, and the determination accuracy can be improved. This is particularly effective when there are characters printed in a special font in the second image information.

(Modification 2)
In the above embodiments and modifications, the first extraction unit 95C and the second extraction unit 95D are used in place of or in addition to the product name, including price, tax-included price, raw material name, expiration date, manufacturer, manufacturer contact information, and manufacturing. One or more product items such as location, production line, shipping service, etc. may be extracted. Even in this case, the correctness of the product label 63 can be determined.

(Modification example 3)
In the above-described embodiment and modification, the label ledger 50 that manages the product labels 63 of the products manufactured by the plurality of manufacturing lines for each of the plurality of manufacturing lines is used, and the correctness of the product labels 63 attached to the label ledger 50 is correct. May be inspected. In the above-described embodiment and modification, the label ledger is not particularly limited, and may be, for example, a ledger that manages the entry / exit of label rolls from the storage.

(Modification example 4)
In the above-described embodiment and modification, the product label inspection unit 96B uses the character string of the product name (product item) as it is as the target of comparison, but is not limited to this. For example, the product label inspection unit 96B may delete a preset specific character from the character string of the product name, and may use the character string from which the specific character is deleted as a comparison target.
