Description

  The present invention relates to an agricultural product traceability system, and more particularly to an agricultural product traceability system capable of recording a history of agricultural products that are subdivided in a distribution process.

  As a basic invention related to a traceability system for agricultural products, there is an invention described in Patent Document 1. In the invention described in Patent Document 1, a different ID number and an access destination for obtaining individual information are pasted for each individual agricultural product, and a distribution history is recorded on a computer of a neutral institution. However, the distribution history can be browsed by accessing the computer of the neutral organization using the access destination.

  In the invention described in Patent Document 1, an ID number must be pasted to each agricultural product. However, an agricultural product that cannot be assigned an ID number to each agricultural product is described in Patent Document 1. The invention cannot be applied. For example, root vegetables such as potatoes, carrots, onions, radishes and burdock, rice grains such as rice, wheat and millet, beans such as soybeans and red beans, fruits such as strawberries and blueberries, leafy vegetables such as spinach, komatsuna and mizuna In addition, there are many agricultural products such as leeks and mushrooms that are practically impossible to attach an ID number to each agricultural product, and the invention described in Patent Document 1 cannot be applied as it is.

  For agricultural products for which the ID number cannot be pasted one by one, the ID number is pasted in a boxed state, in a bag, or in a bundled state. Patent documents 2 to 4 describe conventional techniques in the case of pasting an ID number on such bagged agricultural products, taking rice grains as an example.

  Patent Document 2 discloses a technique for assigning a code “unit rice lot number” of a small bag after rice polishing to a code “unit shipping lot number” of a large bag of brown rice.

  Patent Document 3 discloses a system related to traceability in the case of converting brown rice into brown rice, issuing a barcode or lot number of the shipping brown rice, printing it, and attaching it to a bag. As described in FIG. 6 of Patent Document 3, in the milled rice factory, the brown lot information and the milled rice information are associated with each other and a production lot number is assigned.

  In Patent Document 4, a lot number is assigned each time processing is performed, and each lot number is linked and recorded in a server. This system can also be traced when blending rice.

Japanese Patent No. 3355366 JP 2004-118309 A JP 2005-309902 A Japanese Patent No. 4158710

  However, in the invention described in Patent Document 2, it is provided from the system administrator in a state where the unit rice lot number is associated with the producer in advance. That is, the “unit shipping lot number” of the large bag and the “unit rice lot number” of the small bag are linked and managed in advance. Therefore, when subdividing, it is necessary to affix the “unit rice lot number” of the small bag corresponding to the “unit shipment lot number” of the large bag, which is very troublesome. In addition, in the case of the invention of Patent Document 2, brown rice from a plurality of producers cannot be blended. Also, surplus rice and returned rice cannot be blended. In actual sites, products from various producers are subdivided and commercialized and shipped. Like the technology described in Patent Document 2, the “unit shipment lot number” for large bags and the “ If the “unit rice lot number” is linked and managed in advance, flexible history management cannot be handled. Therefore, the invention described in Patent Document 2 cannot be used practically.

  In the invention described in Patent Document 3, the bar code or lot number of the shipped brown rice is printed and issued each time, and is attached to the bag. In Patent Document 3, it is unclear how the bar code or lot number is pasted for the subdivided polished rice, but if it is considered in the same way as shipped brown rice, it is printed using a printing machine. Conceivable. However, when the producer or processor prints and attaches the barcode, it is necessary to install an appropriate printing machine for the producer or processor. Furthermore, it must be managed by the server so that the same barcode is not issued twice. As described above, it is necessary to request the capital investment of the printing press from producers and the like, and it is very difficult to actually introduce it.

  In the invention described in Patent Document 4, a lot number is issued for each process, recorded on a server, and linked to each piece of information, so that the history is traced back from the final product to the consumer. A traceability system is provided so that it can be viewed, etc., but as in Patent Document 3, it is necessary for the processing company to issue a lot number each time, and the issued lot number is attached to the product. It is necessary to install a printing press. As described above, it is difficult for a producer or the like to introduce a printing machine. Therefore, it is difficult to introduce the invention described in Patent Document 4 as a practical system.

  Thus, conventionally, there has been no system for easily recording distribution and processing history of agricultural products sold in small portions without introducing a printing press or the like. In particular, since the producers of agricultural products are often small and small businesses, there is a need for a system that realizes traceability easily and accurately with as little equipment as possible. In recent years, the need for traceability of agricultural products has been said, but at present, no simple and practical traceability system has been developed. Only history management to the extent that history information is recorded is performed. The development of a traceability system that can realize history management by a simple method while making full use of IT technology is desired.

  Therefore, an object of the present invention is to provide a traceability system for agricultural products that can be easily introduced.

  In order to solve the above problems, the present invention has the following features. The present invention is a crop traceability system for managing a history of crops, and includes a management server for recording history, a producer side terminal capable of communicating with the management server via a network, and a network for the management server. And a processor side terminal that can communicate via the processor side, and a parent code identification object including information on the parent code is provided in advance to the producer who uses the producer side terminal. It is assumed that a processor that uses a terminal is provided with a child code identification object including information on the child code in advance.

  The management server includes recording means, and the recording means records the parent code and the child code without linking them when the parent code identification object and the child code identification object are provided in advance.

  The producer-side terminal includes a first parent code reading unit for reading the parent code identification object, a raw material information association unit for associating raw material information with the parent code read by the first parent code reading unit, A parent code transmission unit that transmits the parent code and the raw material information associated by the raw material information association unit to the management server is included.

  The management server includes receiving means capable of receiving information from the producer side terminal and / or the processor side terminal via the network, and the recording means is transmitted from the producer side terminal. When the parent code and the raw material information are received, the raw material information is linked to the recorded parent code and recorded.

  On the processor side, the processor side terminal includes a second parent code reading means for reading the parent code identification object, a child code reading means for reading the child code identification object, and a child read by the child code reading means. A parent-child association unit for associating the code with the parent code read by the second parent code reading unit; a child code transmission unit for transmitting the child code and the parent code associated by the parent-child association unit to the management server; Including.

  In the management server, when the receiving unit receives the child code and the parent code transmitted from the processor side terminal, the recording unit records the child code in association with the recorded parent code.

  In one embodiment, the processor-side terminal further includes subdivision information association means for associating subdivision information related to the subdivision of agricultural products with the child code read by the subcode reading means.

  Then, the child code transmitting means transmits the division information in association with the child code to the management server, and the recording means in the management server records the division information transmitted from the processor side terminal to the recorded child code. And record.

  In one embodiment, the processor side terminal associates the processing information related to the processing of the agricultural product with the parent code read by the second parent code reading means or the child code read by the child code reading means, Further includes processing information transmitting means for transmitting to.

  In the management server, the recording means records the processing information transmitted from the processor side terminal in association with the recorded parent code or child code.

  Specifically, for example, the processing information includes information related to the yield during processing.

  Preferably, the parent-child association unit may determine whether there is an error in association between the parent code and the child code.

  At this time, the parent-child association unit may determine whether there is an error based on the number of child codes that can be associated with the parent code.

  Further, the parent-child association unit may determine whether there is an error depending on whether the parent code has been shipped or whether the raw material information is linked to the parent code.

  Preferably, the second parent code reading means may determine whether there is an error in the read parent code.

  At that time, the second parent code reading means determines whether or not the parent code has been processed, whether or not material information is linked to the parent code, or whether or not the parent code has been read more than once. Whether or not there is an error may be determined based on whether or not there is an error.

  In one embodiment, in the management server, it is assumed that the recording means can associate the child code and the parent code with respect to the processed residue.

  In one embodiment, in the management server, it is assumed that the recording unit can link the child code and the parent code even to the fraction before being processed.

  In one embodiment, the processor-side terminal reads the child code or the parent code attached to the returned item, the remaining item, or the fraction item, and transmits it to the management server.

  At this time, if the management server receives the child code related to the returned item, the remaining item, or the fractional item, or the data related to the parent code, the child code can be linked to the recording means for the returned item, the remaining item or the fractional item. It shall be managed as follows.

  Further, in one embodiment, the processor-side terminal associates a new child code using the agricultural product with the child code permitted to be linked in the management server as a raw material, and transmits the association to the management server. To do.

  At this time, the management server associates the child codes with each other.

  In one embodiment, the management server may make a determination according to a predetermined standard based on the weight tied to the parent cord and the weight tied to the child cord.

  When the crop is rice cereal, the degree of polished rice recognized by the ratio between the weight tied to the parent cord and the weight tied to the child cord may be used as the predetermined reference.

  The management server may record the determination result.

  According to the present invention, when the parent code identification object and the child code identification object are supplied in advance, they are not linked to each other. Therefore, the producer and the processor can attach the parent code and the child code to the package of the product without worrying about the order of the parent code and the child code and the corresponding relationship. Then, in the processor, after processing, the parent code is associated with the child code for the first time by associating the parent code with the child code, and the parent code is supported by reading the child code and tracking the history. It becomes possible to reach even raw material information. In the present invention, it is troublesome to cause a producer or processor to introduce a printing machine for printing a parent code or a child code, or to issue a lot number or an identification number for each production or processing. Can be omitted at all. According to the present invention, the history of products can be recorded as accurately as possible. Therefore, according to the present invention, in addition to providing a traceability system that is easy to introduce, it is possible to realize product history management as accurately as possible.

  By associating the subdivision information with the child code, it is possible to record the subdivision history.

  By associating the processing information with the parent code or the child code, the processing history can also be recorded.

  By including the yield in the processing information, it is possible to accurately manage the residue and to accurately manage the number of child codes that can be associated with the parent code.

  By performing error determination in the parent-child association unit, it is possible to prevent padding and impersonation due to illegal association.

  By performing error determination in the second parent code reading means, it is possible to prevent padding and forgery due to reading of an illegal parent code.

  By making it possible to link the remaining items, fractional items, and returned items with the child code, it is also possible to record the history of reuse of the remaining items, fractional items, and returned items.

  By allowing the child codes to be linked, it is possible to link the remaining items, fractional items, and returned items to the child code, and record the history of reuse of the remaining items, fractional items, and returned items It is possible to leave.

  Based on the weight attached to the parent cord and the weight attached to the child cord, by making a decision according to a predetermined standard, fraud such as padding or mixing is performed on the product with the child cord attached. It is possible to determine whether it is not.

  For example, when the present invention is used for rice cereals, if the degree of polished rice recognized by the ratio of the weight tied to the parent cord and the weight tied to the child cord is used as a criterion, padding or illegal mixing is performed. In such a case, wrinkles will be generated between the weight ratio and the degree of polished rice. This makes it possible to confirm whether fraud has been performed.

  By recording the determination result, if the determination result remains in the history, it is possible to objectively know where fraud is being performed, so that each contractor is aware that fraud is not performed. .

  Prior to the description of the embodiment of the present invention, four typical patterns when agricultural products are divided and packaged from large bags into small bags will be described. In the following, the term “bag” is used as a large bag or a small bag, but this is only an example of a packaging form, depending on the type of agricultural products such as boxes, bundles, containers, cases, etc. Appropriate packaging can be used properly.

  FIG. 1 is a conceptual diagram showing a processing pattern 1. The processing pattern shown in FIG. 1 is the simplest pattern, and is a case where the processing company “a” divides into one small bag from the producer A and commercializes it. In the present invention, the processor means a supplier that cleans, sorts, or mills the agricultural products from the producer, and the processing method is not particularly limited, and the agricultural products Processing is also performed when only subdivision is performed without any processing. Further, the producer and the processor may be different persons or the same person.

  As shown in FIG. 1, the large bag A shipped from the producer A arrives at the processor a through the intermediate contractor. After arrival, the processor a processes and divides it into small bags a1 to an. At this time, what is less than the capacity of one sachet becomes the remaining sachet an + 1. The sachets a1 to an are shipped and reach the consumer through the middleman and the dealer. The remaining sachet an + 1 will remain at the processor.

  FIG. 2 is a conceptual diagram showing the processing pattern 2. The pattern shown in FIG. 2 is a pattern for mixing agricultural products. For example, in the case of potatoes, when potatoes received from producer A in m large bags are mixed and washed by a processor to make n small bags, or m large bags from producer A In this case, it is assumed that the brown rice that has been received in is mixed and polished by a processor into n sachets. It is also possible to mix large bags from different producers. Even in such a case, a residual sachet an + 1 may occur.

  FIG. 3 is a conceptual diagram showing the processing pattern 3. The pattern shown in FIG. 3 is a pattern in which m sachets are mixed. For example, it may be the case that m small sachets are processed again to make n small sachets. The sachet used is, for example, a fraction sachet that contains a fraction that was left before processing, a sachet of residual material after processing, or a sachet after return. Taking rice as an example, brown rice delivered in large bags of 30 kg from the producer may contain a little more, for example, 33 kg brown rice. When such brown rice is milled to make three 10 kg sachets, depending on the yield, the fraction of brown rice that does not need to be processed becomes a fraction. Also, if all 33 kg is polished, depending on the yield, some 3 grams will remain as a residue when 3 bags of 10 kg are made. In the case of rice, if the returned rice is polished again, it can be sold as a product. Therefore, if a 10 kg bag is returned, the bag can be processed. In this way, the processing pattern 3 is a pattern in which a small bag of fractions, residuals, and returned goods is processed and commercialized. In addition to rice, the state of processing pattern 3 may be similarly applied to each agricultural product.

  FIG. 4 is a conceptual diagram showing the processing pattern 4. The pattern shown in FIG. 4 is a pattern in which large bags and small bags are mixed and processed. In the example shown in FIG. 4, m large bags and k small bags are processed to make n small bags. In this case as well, the small bag an + 1 becomes a residue.

  There are other processing patterns, but the examples of FIGS. 1 to 4 can generally understand the processing patterns of agricultural products. Based on the above, embodiments of the present invention will be described.

  FIG. 5A is a diagram showing devices used in the produce traceability system 1 (hereinafter simply referred to as the system 1) in the embodiment of the present invention. The system 1 includes a management server 2, a barcode printing and issuing device 3, one or more producer-side terminals 4, one or more intermediate supplier-side terminals 5, one or more processor-side terminals 6, and one or more A store side terminal 7 and one or more consumer side terminals 8 are provided. Each device is communicably connected to the management server 2 via a network 9 including a mobile phone network, a wireless or wired LAN network, an optical fiber network, a telephone line network, and the Internet network.

  The management server 2, the barcode print issuing device 3, the producer side terminal 4, the middle trader side terminal 5, the processor side terminal 6, the dealer side terminal 7, and the consumer side terminal 8 are respectively computer devices, An input device, an output device, a control device, a computing device, a recording device (recording means), and a communication device (transmitting means and receiving means) are provided, and the system 1 is realized by executing an installed program. It has become. Hereinafter, characteristic functions of each device will be described.

  The management server 2 has recording means for recording information sent from each device via the network 9, and has a function of associating information recorded in the recording means. In the present invention, associating information is called associating.

  The barcode print issuing device 3 is a device that can issue and print a barcode, and can register information relating to the issued barcode in the management server 2 via the network 9. Here, in order to describe the parent code and child code described later as a barcode, the barcode print issuing device 3 is taken as an example. However, the parent code and child code issued in the system 1 are Any information can be used as long as the parent code and the child code can be managed without duplication, such as a lot number, an identification number, an identification label, and an IC tag. Needless to say, the bar code is not limited to a one-dimensional code but also includes a two-dimensional code. Further, the barcode or the like may be printed or pasted in advance on a large bag or a small bag. When printing on a bag in advance, it is recommended to use a printing device that can print different barcodes one by one. It is preferable to use a device for pasting. Similarly, when using forms other than bags such as boxes, bundles, containers, and cases as packaging, barcodes or the like may be printed or pasted on the packaging in advance. It is preferable that an apparatus capable of performing the above is used. An object including information related to a parent code such as a bar code, lot number, identification number, identification label, and IC tag is referred to as a parent code identification object. Similarly, an object including information related to a child code, such as a bar code, lot number, identification number, identification label, or IC tag, is called a child code identification object. It goes without saying that even when an identification object that is difficult to print is used, such as an IC tag, an identification tag that is previously attached to the package may be used.

  The producer side terminal 4 needs to have a reading means capable of reading the parent code and the child code. The producer side terminal 4 can be realized, for example, by installing a program necessary for a personal computer or information device connected to a barcode reader, but it is assumed as an embodiment that it has a camera function. Future phones, smartphones, and tablet devices. At the time of this application, the producer side terminal 4 assumes a smartphone or a tablet terminal as an optimal example, and installs an application necessary for realizing the system 1 on the producer's smartphone or tablet terminal. Thus, the system 1 can be easily used by a producer. However, it is not limited to these.

  Similarly to the producer-side terminal 4, the intermediate trader-side terminal 5 needs to have a reading unit that can read the parent code and the child code, and the embodiment is the same as the producer terminal 4.

  Similarly to the producer-side terminal 4, the processor-side terminal 6 needs to have a reading unit that can read the parent code and the child code. Similarly to the producer terminal 4, a smartphone or a tablet terminal can be used. In many cases, a processor uses a personal computer connected to a bar code reader.

  Similarly to the producer-side terminal 4, the dealer-side terminal 7 needs to have a reading unit that can read the parent code and the child code, and the embodiment is the same as the producer terminal 4.

  Similarly to the producer side terminal 4, the consumer side terminal 5 needs to have a reading means capable of reading the parent code and the child code, and the embodiment is also the same as the producer terminal 4.

  However, the programs and applications to be installed on the producer side terminal 4, the middle trader side terminal 5, the processor side terminal 6, the store side terminal 7, and the consumer side terminal 8 may be programs necessary for each. Therefore, it is not necessary to be the same program. In particular, since the program to be installed in the producer side terminal 4, the middle trader side terminal 5, the processor side terminal 6, and the dealer side terminal 7 needs to have access restrictions, the specially issued ID is assigned. You must be able to log in without using it. Since the program installed in the consumer terminal 8 only needs to have a browsing function for history information, it is not particularly necessary to provide login restrictions.

  Based on the system configuration as described above, an outline of the operation in the system 1 will be described with reference to FIGS. 5B to 5K. 5B to 5K are illustrated so that the transition of information recorded in the management server 2 can be seen in accordance with the operation of the system 1.

  FIG. 5B is a diagram illustrating a concept of operation of the system 1 at the time of issuing a barcode. First, the barcode print issuing device 3 (hereinafter referred to as the issuing device 3) issues a parent code group sheet on which barcode stickers (parent code identification objects) corresponding to a plurality of parent codes are printed. Next, the issuing device 3 issues a child code group sheet on which barcode stickers (child code identification objects) corresponding to a plurality of child codes are printed. Here, barcodes are taken as an example. However, when a lot number, identification number, or identification label is used as a parent code and a child code, a sheet of a parent code group or a child code group on which a corresponding seal is printed. Is issued by the issuing device 3. When an IC tag is used as the parent code and the child code, the issuing device 3 issues the parent code group and the child code group to which the IC tag is attached. In addition, when printing or pasting unique barcodes, lot numbers, identification numbers, identification labels, etc. on the bag in advance, there are printing devices that can print different barcodes, etc. on each sheet, and devices that can be pasted. It should be used.

  The issuing device 3 registers information related to the parent code and the child code in the management server 2 in accordance with the issue. In response to this, the management server 2 records the parent code and the child code. At this time, the parent code and the child code are only recorded in the management server 2 independently, and each code is not linked.

  In addition, the parent code group is supplied to the producer in advance, and the child code group is supplied to the processor in advance. One of the points of the present invention is this point. When the parent code group is supplied to the producer and the child code group is supplied to the processor, each code is not linked, so the producer and the processor It is not necessary to be aware of which parent code and child code should be used, their order, code contents, correspondence, etc., and be aware of the order and correspondence of the code at hand during production or processing. All you have to do is paste. In addition, when a unique barcode or the like is printed or pasted on the bag in advance, it is not necessary to be aware of the order in which the bags are used or the correspondence relationship during production or lowering. Hereinafter, when a barcode or the like is pasted on the bag and when a barcode or the like is printed on the bag in advance, it is necessary to distinguish between the case where the barcode or the like is attached to the bag. Therefore, in the following explanation, a case where a barcode or the like is pasted on the bag will be described as a representative. In the affixing step, the present invention is understood by replacing the pre-prepared bag with such a bag.

  FIG. 5C is a diagram illustrating a concept of operation of the system 1 when a producer packs a product in a large bag for shipment. The producer appropriately removes the seal from the parent cord group and attaches it to the large bag to be used. There is no need to worry about the order of pasting or correspondence. Then, the producer reads the pasted barcode using the producer side terminal 4. Similarly, when using a seal or IC tag other than the barcode, there is no need to worry about the order, and the producer side terminal 4 has a means for reading a parent code such as a lot number and an IC tag. Shall.

  Next, the producer sends information related to the raw material such as the type of agricultural product, the name of the producer, the production location, the production date, the use history of agricultural chemicals, and the weight (hereinafter referred to as raw material information) to the producer side terminal 4. input. Note that the producer-side terminal 4 may have the producer input and store raw material information in advance. In addition, the producer inputs information relating to shipping (hereinafter referred to as shipping information) such as a shipping location, a shipping destination, and a shipping date and time into the producer-side terminal 4. Note that the producer-side terminal 4 may allow the producer to input and store frequently used shipping information such as a shipping location and a shipping destination in advance. Note that the weight of the raw material may be input to the shipping information.

  When the input of the raw material information and the shipping information is completed, the producer side terminal 4 associates the read parent code with the raw material information and the shipping information and transmits them to the management server 2. As a result, as shown in FIG. 5C, the raw material information and the shipping information are linked to the parent code (A1 to Am in the figure) and recorded in the recording means of the management server 2.

  Next, it is assumed that the large bag with the parent code A1 is delivered directly from the producer to the processor. FIG. 5D is a diagram illustrating a concept of operation of the system 1 when a processor receives a large bag. The processor uses the processor-side terminal 6 to read the parent code attached to the large bag. When using a seal or IC tag other than the bar code, the processor terminal 6 is assumed to include a parent code reading unit such as a lot number or an IC tag.

  After reading the parent code, the processor inputs information related to arrival (hereinafter referred to as arrival information) such as the arrival location, the shipping origin, and the arrival date and time into the processor-side terminal 6. In addition, the processor side terminal 6 may be configured to allow the processor to input frequently used arrival information such as an arrival place and a shipping source and store the information in advance.

  When the input of the arrival information is completed, the processor-side terminal 6 associates the read parent code with the arrival information and transmits it to the management server 2. As a result, as shown in FIG. 5D, the arrival information is associated with the parent code (A1 in the figure) and is recorded in the recording means of the management server 2.

In addition, the processor side terminal 6 may be configured to allow a processor to input and store frequently used processing information such as the name of the processor, a processing place, and a processing method in advance. .

  When the input of the processing information is completed, the processor-side terminal 6 associates the read parent code with the processing information and transmits it to the management server 2. As a result, as shown in FIG. 5E, the processing information is associated with the parent code (A1 in the figure) and recorded in the recording means of the management server 2. Here, the processing information is associated with the parent code, but the processing information may be associated with the child code attached to the processed product.

  FIG. 5F is a diagram showing the concept of the operation of the system 1 when the processor packs the sachet. The processor properly removes the seal from the cord group and attaches it to the sachet to be used. There is no need to worry about the order of pasting or correspondence. Then, the processor reads the barcode of the attached child code (the child codes a1 to an in FIG. 5F) using the processor-side terminal 6. Similarly, when using a seal or IC tag other than the bar code, there is no need to worry about the order, and the processor side terminal 6 has a means for reading a child code such as a lot number or an IC tag. Shall.

  Next, the processor inputs information about the subdivision (hereinafter referred to as subdivision information) such as a subdivision unit (quantity, mass, capacity) and a subdivision method to the processor side terminal 6. In addition, the processor side terminal 6 may be configured to cause the processor to input and store frequently used subdivision information such as a subdivision unit and a subdivision method in advance.

  When the input of the subdivision information is completed, the processor side terminal 6 associates the subdivision information with the child code, and associates the parent code with the child code, and transmits it to the management server 2. As a result, as shown in FIG. 5F, the subcode information is associated with the child code (a1 to an in FIG. 5F), and the parent code (a1 to an in FIG. 5F) is connected to the parent code (in FIG. 5F, A1) will be tied. When there are a plurality of child codes, for example, the child code a1 may be subdivided into 3 kilometers, and the child code an may be associated with different subdivision information for each child code, such as 5 kilometers.

  At the time of FIG. 5F, the parent code and the child code are associated with each other for the first time. Up to this point, the producer and processor choose the appropriate seal from the provided parent or child code group without worrying about the order or correspondence of the parent or child code to be pasted, and put it in the bag. The information is simply sent to the management server 2 using each terminal. As described above, the system 1 of the present invention can appropriately record the history on the management server 2 even though the method of use is very simple.

  FIG. 5G is a diagram showing the concept of the operation of the system 1 when the processor ships the sachets. The processor reads the barcode from the pouch. The processor inputs the shipping information to the processor side terminal 6. The processor side terminal 6 may allow the processor to input and store frequently used shipping information such as a shipping location and a shipping destination in advance.

  When the input of the shipping information is completed, the processor-side terminal 6 associates the read child code with the shipping information and transmits it to the management server 2. As a result, as shown in FIG. 5G, the shipping information is associated with the child code (a1 to an in the figure) and recorded in the recording means of the management server 2.

  FIG. 5H is a diagram illustrating a concept of operation of the system 1 when the intermediate contractor receives a large bag. The intermediate trader uses the intermediate trader side terminal 5 to read the parent code (parent code A1 in the figure) attached to the large bag. In the case of using a seal or IC tag other than the barcode, it is assumed that the intermediate trader side terminal 5 includes a parent code reading unit such as a lot number and an IC tag.

  After reading the parent code, the intermediate company inputs the arrival information to the intermediate company side terminal 5. In addition, the intermediate trader side terminal 5 may be configured to allow the intermediate trader to input frequently used arrival information such as the arrival place and the shipping source and store the information in advance.

  When the input of the arrival information is completed, the intermediate trader side terminal 5 associates the read parent code with the arrival information and transmits it to the management server 2. As a result, as shown in FIG. 5H, the arrival information is linked to the parent code (A1 in the figure) and recorded in the recording means of the management server 2. In this way, the history of the distribution process in the middle is also recorded in the management server 2.

  FIG. 5I is a diagram illustrating a concept of operation of the system 1 when an intermediate contractor ships a large bag. The intermediate trader uses the intermediate trader side terminal 5 to read the parent code (parent code A1 in the figure) attached to the large bag.

  After reading the parent code, the intermediate contractor inputs the shipping information to the intermediate contractor side terminal 5. In addition, the intermediate trader side terminal 5 may be configured to cause the intermediate trader to input frequently used shipping information such as a shipping location and a shipping destination and store the information in advance.

  When the input of the shipping information is completed, the intermediate trader side terminal 5 associates the read parent code with the shipping information and transmits it to the management server 2. As a result, as shown in FIG. 5I, the shipping information is associated with the parent code (A1 in the figure) and recorded in the recording means of the management server 2. In this way, the history of the distribution process in the middle is also recorded in the management server 2.

  FIG. 5J is a diagram illustrating a concept of operation of the system 1 when an intermediate trader (or a dealer) receives a small bag. The middle trader uses the middle trader side terminal 5 to read the small code (child code a1 in the figure) attached to the pouch. In the case of using a seal or IC tag other than the bar code, the intermediate trader side terminal 5 is provided with a reading means for reading a child code such as a lot number and an IC tag.

  After reading the child code, the intermediate contractor inputs the arrival information to the intermediate contractor side terminal 5. In addition, the intermediate trader side terminal 5 may be configured to allow the intermediate trader to input frequently used arrival information such as the arrival place and the shipping source and store the information in advance.

  FIG. 5K is a diagram showing a concept of the operation of the system 1 when an intermediate contractor ships a small bag. The intermediate contractor uses the intermediate contractor side terminal 5 to read the child code attached to the pouch.

  After reading the child code, the intermediate company inputs the shipping information to the intermediate company side terminal 5. In addition, the intermediate trader side terminal 5 may be configured to cause the intermediate trader to input frequently used shipping information such as a shipping location and a shipping destination and store the information in advance.

  When the input of the shipping information is completed, the intermediate trader-side terminal 5 associates the read child code with the shipping information and transmits it to the management server 2. As a result, as shown in FIG. 5K, the shipping information is associated with the child code (a1 in the figure) and recorded in the recording means of the management server 2. In this way, the history of the distribution process in the middle is also recorded in the management server 2.

  Up to now, using FIG. 5B to FIG. 5K, while showing the transition of information in the management server 2 for an example of the operation of the system 1 when n small bags are linked to one large bag, ,explained. Note that the data structures shown in FIGS. 5B to 5K are merely described so as to make it easy to imagine the association situation, and the actual data structures are not particularly limited.

  Next, the data structure in the management server 2 when complicated association is performed will be described with reference to FIGS. 6A to 6D. In addition, although the description about the linking of the arrival information and the shipping information at the intermediate trader or the store is omitted, as shown in FIGS. 5H to 5K, the arrival information and the shipping information are associated with each code. To go.

  FIG. 6A is an example of a data structure when a small bag is made from a plurality of large bags. Here, a case where large bags A1 to Am are used for the small bags a1 to an is shown. As shown in FIG. 6A, the parent codes A1 to Am are linked to the child code a1. Further, the parent codes A1 to Am are linked to the child code an. As described above, since it is possible to link a plurality of parent codes to a child code, even when there are a plurality of large bags as raw materials contained in a commercialized pouch, a history is recorded and viewed. become able to.

  FIG. 6B is an example of a data structure when a sachet is made from a plurality of sachets. An example of making a sachet from a sachet is when the sachet as a raw material is a residue, a returned product, or a fraction. Here, it is shown that the large bags B1 to Bp that are the original raw materials are used for the small bags b1 to bm that are the raw materials. The association between the child codes b1 to bm and the parent codes B1 to Bp is the same as in the example of FIG. 6A. The child cords b1 to bm are associated with the child cords a1 to an of the small bags a1 to an. Thus, since it is possible to link the child code to the child code, even when the raw material of the commercialized sachet is a sachet, a history is recorded and can be viewed. In the management server 2, the child code can be associated with the child code when the remaining flag, the return flag, or the fraction flag is attached. However, the present invention is not limited to this. The example of FIG. 6B is an embodiment of the invention according to claim 13. In addition, although there is a description referring to the claims in the specification, this is merely given as an example to help the understanding of the claims, and is not intended to limit the present invention. Needless to say, it should be added (the same is true for other descriptions).

  FIG. 6C is an example of a data structure in a case where a large bag as a raw material is made from a plurality of large bags. An example in which a large bag is made from a large bag is a modification of the example shown in FIG. 5F, and specifically, a case where a processor receives a large bag and mixes the received large bag to make a large bag. In this case, the parent codes C1 to Cq are associated with the parent codes A1 to Am. Normally, the parent code cannot be associated with the parent code, but as a special case, the processor terminal 6 can obtain permission from the management server 2 so that the parent code can be associated with the parent code. Make sure that you can do this. Thereby, it becomes possible to go back to the history of the raw material of the large bag that is the raw material of the small bag. If the producer himself is making a large bag by mixing multiple ingredients, the producer may enter the raw material information in the raw material information to leave a history of the raw material in the large bag. Good.

  FIG. 6D is an example of a data structure in the case where a small bag is made from a large bag and a small bag as raw materials. The child cord b1 is made from the large bags B1 to Bp, as in the case shown in FIG. 6B. The raw materials of the small cords of the child cords a1 to an are assumed to be the small bag of the child cord b1 and the large bag of the parent cord Am. In this way, history traces are possible even when small bags and large bags are used as raw materials.

  The example of the data structure is merely an example in the embodiment of the present invention, and does not limit the present invention. Any data structure can be used as long as the object of the present invention can be achieved. It may be a simple data structure.

  The reason why the linked data structure as shown in FIGS. 6A to 6D is possible will be further clarified by the flowchart described in FIG.

  Here, an example of display when the consumer side terminal 8 reads the child code will be described. FIG. 7 is a diagram illustrating an example of display. In the example shown in FIG. 7, it is assumed that the sachet delivered to the consumer is commercialized by the raw materials A, B, C contained in the three large bags and the other raw materials contained in the sachet. . In terms of the data structure, the data structure is similar to the data structure of FIG. 6D, and the raw materials of the sachets that have arrived at the consumer are three large bags of raw materials A, B, and C and one sachet of other raw materials. It is.

  As shown in FIG. 7, the display example is roughly divided into a “product information” column and a “distribution history” column. In the “product information” column, a product name, a capacity, a production area, and the like are displayed, but information obtained from subdivision information is mainly displayed. Specifically, when the consumer side terminal 8 reads the child code and accesses the management server 2, the management server 2 enters the “product information” column from the information associated with the received child code. The information to be displayed is extracted and transmitted to the consumer side terminal 8, and the information sent from the consumer side terminal 8 is displayed. It is not necessary to transmit all the information recorded in the management server 2 to the consumer side terminal 8, and public information and non-public information are clearly distinguished on the management server 2, and only the public information is available to the consumer. It is transmitted to the side terminal 8. In addition, information such as a producer name obtained from the raw material information may be used as the information displayed in the “product information” column.

  Next, the “distribution history” column will be described. The “distribution history” column is broadly divided into an A column for “raw material display / distribution history”, a B column for “commercialization history”, and a C column for “product distribution history”. In column A, the raw materials used are displayed. As the information displayed in the A column, the raw material information of the parent code linked to the child code is used. However, since the other examples in the display are child codes linked to the child codes, here, as other items, the raw material can be understood by checking further deeply.

  For example, when the raw material A is clicked or tapped, the raw material distribution history is displayed in detail. In the example shown in FIG. 7, for the raw material A, the collector and the processing factory can be confirmed from the producer. The raw materials B and C are the same as the raw material A. When other materials are clicked, tapped, etc., columns A to C are further displayed as other material information. Although not shown, for example, when other raw materials are made from a plurality of raw materials, tap the column A of the other raw material information display, and the raw materials contained in the other raw materials will be displayed. Will be displayed. Further information on the B column and the C column of other raw materials is displayed by tapping the column.

  In column B, the merchandising history is displayed, but on the data structure, information displayed in column B is extracted from the processing information associated with the parent code. If processing information is associated with the child code, information displayed in the B column may be extracted from the processing information associated with the child code.

  In the column B, when a processor entrusts processing to another processor (consignment processing), a merchandising history at the second processing factory is displayed.

  In column C, the distribution history of the product is displayed. In terms of the data structure, it is assumed that information displayed in the C column is extracted and displayed from the arrival information and the shipment information associated with the parent code and the child code.

  In addition, since the trace of the arrival information in a store is arbitrary on the system 1, when there is no arrival information in a store, the column of a store name shall be a blank.

  An outline of how the history information traced by the system 1 is displayed on the consumer terminal 8 by the example of the data structure shown in FIGS. 6A to 6D and the example of the display shown in FIG. Understandable. Note that the display examples shown here are merely examples, and do not limit the present invention.

  Based on the above general understanding, the operation of the system 1 will be described in detail with reference to a flowchart.

  FIG. 8 is a flowchart showing the overall flow of the system 1. Hereinafter, the overall flow of the system 1 will be described with reference to FIG. In FIG. 8, record information recorded in the management server 2 is described in parentheses.

  First, the producer performs a shipping process using the producer side terminal 4 (S101). At this time, the raw material information and shipping information associated with the parent code are recorded in the management server 2.

  Next, the intermediate contractor who has obtained the raw material from the producer performs an arrival process using the intermediate contractor side terminal 5 (S102), and performs a shipping process (S103). At this time, arrival information and shipping information associated with the parent code are recorded in the management server 2.

  Next, in the processing factory G that has obtained the raw material from the intermediate contractor, the processing is performed using the processor terminal 6 (S104). At this time, arrival information associated with the parent code is recorded in the management server 2. When the received raw material is a returned product, the processor uses the processor terminal 6 to set a returned product flag for the child code (or parent code) given to the returned product. If the received raw material is a residue, the processor uses the processor terminal 6 to set a residue flag for the child code assigned to the residue. If the received raw material is a fraction, the processor uses the processor terminal 6 to set a fraction flag for the child code assigned to the fraction. Returned items, residuals, and fractional items will be described later.

  The processor stores the raw material after the raw material arrival processing (S104). When the raw material is processed after storage (S105), the processor terminal 6 associates the processing information with the parent code of the raw material. Here, at the time of processing, the weight before processing is measured (S106), the weight after processing is measured (S107), the weight before processing and the weight after processing are calculated, and the yield at the time of processing is calculated ( S108), the yield is included in the processing information. At this time, processing information including the yield associated with the parent code is recorded in the management server 2. When processing information is associated with a child code, the processing information is associated with the child code in the operation of S110. Note that the weight before processing and the weight after processing are not recorded in the management server 2 including the respective numerical values and their differences.

  In the processing of S105, a single raw material is used, but a plurality of raw materials may be used. Therefore, when processing a plurality of raw materials in parallel with the processing of S105, processing of S106, S107, and S108 is performed on other raw materials as in S109, and processing information is obtained to obtain other raw materials. The processing information is associated with the parent code. The raw material may be three or more, and even when three or more raw materials are used, the processing of S106, S107, and S108 is performed for each raw material, processing information is obtained, and the processing information is associated with the parent code. To do.

  If the raw material is a returned product, a remaining product, or a fraction, the processing information is associated with the child code of the returned product, the remaining product, or the fraction in S108.

  During processing, fractions may appear. In that case, a child code is assigned to the fractional thing, and fractional part information (described later) is associated with it and recorded in the management server 2 (S111).

  Moreover, a residue may appear after processing. In this case, as shown in S112, a child code is assigned to the residue, and the residue information (described later) is associated and recorded in the management server 2 (S112).

  In S110, the processed product is subdivided and commercialized. At this time, the parent code as a raw material and the commercialized child code are recorded in the management server 2 in association with each other, and the child code is recorded in the management server 2 in association with the input subdivision information.

  In the case where processing is outsourced to a factory other than the processing company G, it is recorded in the management server 2 so that it can be understood that the processing is outsourced.

  After the subdivision, the processor G ships the subdivided products (S113). At this time, the management server 2 associates the shipping information with the child code. When the processing is performed by the processor H after the shipment, the processing information, the subdivision information, and the shipping information are associated with the parent code or the child code in the same manner as S105 to S110. In addition, it is also conceivable that the processor G sends the product just attached with the parent code to the processor H without processing. In this case, it is assumed that the processor H associates the parent code of the large bag with the child code after commercialization in the same manner as the operation of the previous processor G.

  Thereafter, assuming that the merchandise arrives at the middle trader, the middle trader associates the receipt information with the child code using the middle trader side terminal 5 (S115). Accordingly, the management server 2 records the arrival information in association with the child code. Next, if the intermediate company has shipped the product, the intermediate company uses the intermediate company side terminal 5 to associate the shipping information with the child code (S116). Thereby, the management server 2 records the shipment information in association with the child code.

  Finally, if a product arrives at the store, the store associates the arrival information with the child code using the store side terminal 7 (S117). Accordingly, the management server 2 records the arrival information in association with the child code. Note that it is arbitrary whether the store records the arrival information.

  When the store returns the unsold item, the returned item arrives at the processor G (S118). At this time, the processor G uses the processor-side terminal 6 to associate information related to returns (hereinafter referred to as returned product information) such as the return date and time from the child code of the returned product. At the same time, the processing server side 6 is used to cause the management server 2 to attach a return flag corresponding to the child code. As an irregular case, products sold with the parent code attached will be handled as returned goods with the parent code attached. In addition, it is assumed that the returned goods information and the returned goods flag can be used for processing.

  Based on the overall operation described above, the detailed operation of each terminal will be described with reference to the flowchart in FIG.

  FIG. 9 is a flowchart showing the operation of the producer side terminal 4. The producer side terminal 4 reads the parent code of the large bag (S201: first parent code reading means). Next, the producer side terminal 4 makes the producer input the raw material information of the product contained in the large bag (S202). Next, the producer-side terminal 4 causes the producer to input shipping information (S203). Then, the producer-side terminal 4 associates the parent code with the raw material information and the shipping information (raw material information associating means), and transmits data to the management server 2 (S204: parent code transmitting means). The management server 2 receives the data from the producer side terminal 4, and stores the parent code, the raw material information, and the shipping information in association with each other (S205).

  FIG. 10 is a flowchart showing the operation of the intermediary-side terminal 5 that has received a large bag. The intermediate trader side terminal 5 reads the parent code of the large bag (S301). Next, the intermediate trader side terminal 5 causes the intermediate trader to input the arrival information (S302). Then, the intermediate trader-side terminal 5 associates the parent code with the arrival information and transmits data to the management server 2 (S303). The management server 2 receives the data from the intermediate trader side terminal 5 and stores the parent code and the arrival information in association with each other (S304).

  Next, when shipping, the intermediate trader side terminal 5 reads the parent code of the large bag (S305). Next, the intermediate trader side terminal 5 causes the intermediate trader to input shipping information (S306). Then, the intermediate trader-side terminal 5 associates the parent code with the shipping information and transmits data to the management server 2 (S307). The management server 2 receives the data from the intermediate trader side terminal 5, and stores the parent code and the shipping information in association with each other (S308).

  FIG. 11 is a flowchart showing the operation of the processor side terminal 6 that has received a large bag. The processor side terminal 5 reads the parent code of the large bag (S401). Next, the processor side terminal 6 causes the intermediate trader to input the arrival information (S402). Then, the processor-side terminal 6 associates the parent code with the arrival information and transmits data to the management server 2 (S403). The management server 2 receives the data from the processor side terminal 6 and stores the parent code and the arrival information in association with each other (S404).

  FIG. 12 is a flowchart showing the operation of the processor side terminal 6 when the processor processes the raw material. The processor side terminal 5 reads the parent code of the large bag (S501: second parent code reading means). Next, the processor-side terminal 6 performs error determination as to whether or not impersonation has been performed (S502: Error determination of second parent code reading means). Various error determinations can be considered here, but an example will be described below.

  For example, if a processed parent code is read, it is determined that an error has occurred. As a result, it becomes impossible to read the parent code of the parent bag attached to the already empty bag and use the product used for camouflage. This determination may be performed by the processor-side terminal 6 itself, or the management server 2 determines, sends the determination result back to the processor-side terminal 6, and the processor-side terminal 6 notifies the error. Also good. The same applies to other error determinations described later.

  Further, when a child code to which the return flag, the remaining flag, and the fraction flag are not read is determined as an error. This prevents the child code from being read and the product disguised.

  If a parent code to which no material information is assigned is read, it is determined that an error has occurred. If the raw material information is not given, it means that the product is not properly shipped by the producer, so this empty parent code can be read to prevent padding or fraudulent production. be able to.

  If the parent code is read twice, it is determined that an error has occurred. Thereby, it is possible to prevent the disguised product from being padded with the parent code being read twice or more.

  In addition, the error process for the camouflage determination shown above is only an example, and various other camouflage determinations can be used in the present invention. When reading the parent code, it is only necessary to execute error processing so that padding and production area disguise are not performed.

  If there is an error, in S508, the processor-side terminal 6 displays to notify the processor of the error, and stops so as not to proceed to the next processing (S509). This prevents the processor from performing an act that is suspected of being camouflaged that would cause an error. Note that after the stop, the processor-side terminal 6 may request rereading.

  If there is no error, the processor side terminal 6 causes the processor to input processing information (S503). At this time, the yield is not yet determined at this point, but the yield may be input as processing information from the past experience value without performing the measurement in S504 described later.

  After S503, the processor side terminal 6 allows the processor to input the weight before processing and the weight after processing (S504). Next, the processor side terminal 6 calculates the yield from the weight before processing and the weight after processing (S505). The yield obtained by this calculation is added to the machining information. Note that the operation of S503 may be performed after the operations of S504 and S505. Note that the weight before processing and the weight after processing are not recorded in the management server 2 including the respective numerical values and their differences.

  The processor-side terminal 6 associates the parent code with the processing information and transmits data to the management server 2 (S506: processing information transmission means). The management server 2 receives the data from the processor side terminal 6 and stores the parent code and the processing information in association with each other (S507). In the embodiment in which the child code is associated with the processing information, the child code and the processing information are associated with each other and transmitted to the management server 2 in S708 of FIG.

  FIG. 13 is a flowchart showing the operation of the processor side terminal 6 when the processor processes fractions. When the processor packs the fractions (S601), the processor-side terminal 6 reads the child code of the packed fractions (S602). Next, the processor side terminal 6 associates the read child code with the parent code as the raw material (S603). At this time, when a plurality of raw materials are used, a plurality of parent codes are associated with the read child code. In addition, when the residue or fraction is a raw material, the child code of the residue or fraction is associated with the read child code. When the returned item is a raw material, the child code (or parent code) of the returned item is associated with the read child code.

  Next, the processor side terminal 6 causes the processor to input information about the processor from which the fraction is obtained and information about the fraction such as the date and time (referred to as fraction information) (S604). After that, the processor-side terminal 6 transmits data related to the parent code corresponding to the child code and fractional information corresponding to the child code to the management server 2 (S605). The management server 2 receives the data from the processor side terminal 6 and stores the child code and the parent code in association with each other and stores the fractional object information in association with the child code (S606: Claim). 11).

  FIG. 14 is a flowchart showing the operation of the processor side terminal 6 at the time of subdivision after processing. After the processor performs the subdivision work (S701), the processor-side terminal 6 reads the child code attached to the pouch (S702: child code reading means). Then, the processor terminal 6 causes the processor to input the subdivision information, and associates the child code with the subdivision information (S703: subdivision information association unit).

  In S703, the subdivision information is input for each child code. For example, for the child code a1, the information of 10 kilos is input as the subdivision information, for the child code a2, the information of 10 kilos is input as the subdivision information, and as the subdivision information for the child code a3. Information of 5 km can be input, and information of 2 km can be input as subdivision information for the child code a4.

  Next, the processor side terminal 6 associates the read child code with the parent code as the raw material (S704: parent-child association means). At this time, when a plurality of raw materials are used, a plurality of parent codes are associated with the read child code. In addition, when the residue or fraction is a raw material, the child code of the residue or fraction is associated with the read child code. When the returned item is a raw material, the child code (or parent code) of the returned item is associated with the read child code.

  Next, the processor terminal 6 executes an error determination regarding the number of links (S705: error determination of parent-child association unit). Various types of error processing relating to the number of links can be considered. For example, the following examples can be considered. For example, the upper limit value of the child code that can be linked to the parent code is calculated in consideration of the yield and weight when subdividing, so that the child code exceeding the upper limit value cannot be associated with the parent code. For example, in the case of rice grains, if the parent code has 30 kg of raw material information and the yield is 90%, 10% is garbage such as rice bran and stones at the time of milling. Therefore, even 30 kg of brown rice is 27 kg after milling. Therefore, if a small code is used for a 5-kg small bag, the upper limit of the number of child codes associated with the parent code is 5 kg × 5 bags = 25 km. If child codes are used for 10 kg, 5 kg, and 2 kg sachets, four codes of 10 kg × 2 bags, 5 kg × 1 bag, and 2 kg × 1 bag are associated with the parent code. It turns out that. In addition, it is possible to associate 10 kg × 1 bag, 5 kg × 3 bag, and 2 kg × 1 bag. There are various other combinations, but in any case, the upper limit of the number of child codes associated with the parent code is determined in consideration of the weight to be subdivided. Depending on the way of subdivision, the remainder after processing comes out as a residue, but handling of the residue will be described with reference to the flowchart of FIG. 15 described later. Note that the error processing of the number of links is not limited to the above, and it is only necessary to determine a case where a combination in which the parent code and the child code are not theoretically established is an error. .

  For example, if information such as 10 kg × 2 bags, 5 kg × 1 bag, 2 kg × 2 bags is entered as subdivision information in S703, the parent code material is 30 kg, and the yield is 90%. Since one bag of 2 kilograms does not hold in theory, it is determined as an error.

  If there is an error in the error processing of S705, the processor side terminal 6 gives an error notification (S710). After the error notification, the processor-side terminal 6 may stop the process or request the process again.

  Next, if it is determined that there is no error in the error processing in S705, the processor-side terminal 6 executes error processing for the correspondence relationship in S706 (error determination of the parent-child association unit). The error processing for the correspondence relationship is an example as follows.

  For example, it is preferable that the child code is not associated with the parent code that has already been associated with the shipped child code. Further, a child code may not be associated with a parent code that is not associated with raw material information.

  If there is an error in the error processing in S706, the processor-side terminal 6 issues an error notification (S710) and requests to stop the process or restart the process.

  When it is determined that there is no error in the error processing of S706, the processor-side terminal 6 transmits data relating to the child code and the parent code associated therewith to the management server 2 and is associated with the child code. Data relating to the subdivision information is transmitted to the management server 2 (S708: child code transmitting means).

  The management server 2 that has received the data from the processor side terminal 6 associates the child code with the parent code, and associates the child code with the subdivision information and records it (S709).

  FIG. 15 is a flowchart showing the operation of the processor side terminal 6 with respect to the residue. It is assumed that after the processor performs subdivision work (S801), a residue is made. At this time, the processor terminal 6 reads the child code attached to the pouch (S802). Then, the processor terminal 6 causes the processor to input information about the residue such as the weight of the residue and the date and time of occurrence (referred to as residue information), and associates the residue information with the child code (S803).

  Next, the processor-side terminal 6 associates the child code of the residue with the parent code as the raw material (S804: Example of the invention according to claim 10). At this time, when a plurality of raw materials are used, a plurality of parent codes are associated with the read child code. In addition, when the residue or fraction is a raw material, the child code of the residue or fraction is associated with the read child code. When the returned item is a raw material, the child code (or parent code) of the returned item is associated with the read child code.

  As for the residue, the following cases are considered as an example. For example, in the case of rice cereals, if the parent code has 30 kg of raw material information and the yield is 95%, 5% is garbage such as straw and stones at the time of milling. Therefore, even with 30 kg of brown rice, it will be 28.5 kg after milling. At this time, if it is subdivided into 10 kg × 2 bags, 5 kg × 1 bag, 2 kg × 1 bag, 1.5 kg will be the remainder.

  Normally, the remaining amount corresponds to one bag. Therefore, if the residual information is associated with the child code, the child code can be associated with the parent code as being excluded from the error determination in S705 of FIG. It shall be possible.

  After that, in S805, as in FIG. 14, the correspondence error determination is performed. If there is no error, the processor terminal 6 transmits the child code and data related to the parent code associated therewith to the management server 2. At the same time, data related to the residual information associated with the child code is transmitted to the management server 2 (S806). The management server 2 receives the data from the processor side terminal 6 and associates the child code with the parent code associated therewith, and associates the child code with the associated residual information. (S807).

  FIG. 16 is a flowchart showing the operation at the time of shipment at the processor side terminal 6. The processor side terminal 6 reads the child code of the pouch (S901). Next, the processor side terminal 6 performs error determination (S902). This error determination is a process for determining whether or not the subdivision information and the parent code are associated with the child code. At the time of shipment, it is determined again that there is no omission in the association and no history is recorded. This is a process for preventing the product from being shipped accidentally or preventing the disguised product from being shipped.

  If there is an error in S902, the processor side terminal 6 gives an error notification (S906) and prompts the processor to perform reprocessing.

  If there is no error in S902, the processor-side terminal 6 causes the processor to input shipping information (S903), and transmits data in which the child code is associated with the shipping information to the management server 2 (S904). The management server 2 receives the data from the processor side terminal 6 and records the child code and the shipping information in association with each other (S905).

  FIG. 17 is a flowchart showing the operation of the intermediary side terminal 5 that has received a small bag. The intermediate trader side terminal 5 reads the child code of the pouch (S1001). Next, the intermediate trader side terminal 5 causes the intermediate trader to input the arrival information (S1002). Then, the intermediate trader-side terminal 5 associates the child code with the arrival information and transmits data to the management server 2 (S1003). The management server 2 receives the data from the intermediate trader side terminal 5 and stores the child code and the arrival information in association with each other (S1004).

  FIG. 18 is a flowchart showing the operation of the intermediate trader side terminal 5 when shipping a small bag. When shipping, the intermediate trader side terminal 5 reads the child code of the pouch (S1101). Next, the intermediate trader side terminal 5 causes the intermediate trader to input shipping information (S1102). Then, the intermediate trader side terminal 5 associates the child code with the shipping information and transmits data to the management server 2 (S1103). The management server 2 receives the data from the intermediate trader side terminal 5, and stores the child code and the shipping information in association with each other (S1104).

  FIG. 19 is a flowchart showing the operation of the store-side terminal 7 that has received a small bag. The store side terminal 7 reads the child code of the small bag (S1201). Next, the store side terminal 7 causes the store to input arrival information (S1202). Then, the store-side terminal 7 associates the child code with the arrival information and transmits data to the management server 2 (S1203). The management server 2 receives the data from the store side terminal 7 and stores the child code and the arrival information in association with each other (S1204).

  FIG. 20 is a flowchart showing an operation when the processor-side terminal 6 accepts a returned item (Example of the invention according to claim 12). When the processor accepts the returned item (S1301), the processor-side terminal 6 reads the child code (or parent code) attached to the returned item (S1302). Next, the processor-side terminal 6 causes the processor to input information (referred to as returned item information) such as the reception date and time of the returned item and the return source (S1303). Next, the processor-side terminal 6 transmits data in which the read child code (or parent code) and returned item information are associated with each other to the management server 2 (S1304). Based on the data transmitted from the processor-side terminal 6, the management server 2 records the returned item information in association with the child code (or parent code) (S1305), and returns it to the child code (or parent code). A flag is assigned (S1306). From now on, the management server 2 can manage the child code (or parent code) to which the return flag is attached so that the child code can be further linked, and the returned item can be reused and traced. To.

  FIG. 21 is a flowchart showing the operation when the processor terminal 6 accepts a remaining item (Embodiment of the invention according to claim 12). When the processor accepts the residue, the processor-side terminal 6 reads the child code attached to the residue (S1401). Next, the processor-side terminal 6 causes the processor to input information (residual information) related to the reception date and time of the residual, the generation source of the residual, etc. (S1402). Next, the processor-side terminal 6 transmits data in which the read child code is associated with the residual information to the management server 2 (S1403). Based on the data transmitted from the processor side terminal 6, the management server 2 records the residual information in association with the child code (S1404), and adds a residual flag to the child code (S1404). After that, the management server 2 manages the child code to which the residual flag is assigned so that the child code can be further linked so that the residual can be reused and traced.

  FIG. 22 is a flowchart showing an operation when the processor terminal 6 accepts a fraction (Example of the invention according to claim 12). When the processor accepts the fraction, the processor-side terminal 6 reads the child code attached to the fraction (S1501). Next, the processor-side terminal 6 causes the processor to input information (fractional information) about the reception date of the fraction, the generation source of the fraction, etc. (S1502). Next, the processor-side terminal 6 transmits data associating the read child code with the fraction information to the management server 2 (S1503). Based on the data transmitted from the processor-side terminal 6, the management server 2 records the fractional information linked to the child code (S1504), and adds the fractional part flag to the child code (S1504). After that, the management server 2 manages the child code to which the fractional part flag is assigned so that the child code can be further linked, so that the fractional part can be reused and traced.

  FIG. 23 is a flowchart showing an operation at the time of display on the consumer side terminal 8. The consumer side terminal 8 reads the child code affixed to the pouch (S1601). The child code includes connection information (URL and the like) related to the network 9, and the consumer side terminal 9 connects to the management server 2 via the network 9 based on the connection information, and the management server 2. The child code information is transmitted to the management server 2 and communication with the management server 2 is started (S1602). The management server 2 transmits the information permitted to be disclosed to the consumer side terminal 8 based on the data related to the child code received from the consumer side terminal 8. As a result, the consumer side terminal 8 receives the information permitted to be released (S1603) and displays it (S1604).

  As described above, in the embodiment of the present invention, the management server 2 associates the parent code identifier and the child code identifier, which are initially issued separately, in the processor, so that the management server 2 Can be linked. As a result, a consumer who has received a product with a child code identification object can read the child code and view the raw material of the parent code, distribution history, processing history in commercialization, etc. It becomes possible. In the system 1 of the present invention, it is not necessary to introduce a printing machine for issuing a parent code on the producer side or a printing machine for issuing a child code on the processor side. When a parent code or a child code is attached to a package, it can be used without worrying about the order or correspondence of each code. Therefore, a producer or a processor can easily introduce the system 1 and use it easily.

  Needless to say, the management server 2 may be realized not only by a single server but also by the cooperation of a plurality of servers.

  Here, a dedicated application for reading the code will be described. Dedicated apps run on various terminals. When the code is read by the dedicated application, the terminal communicates with the management server 2 or a server for decoding on the network or decodes the information in the code by the decoder in the application and transmits the information to the management server 2. The management server 2 transmits a data set of history information corresponding to the decoded information to the terminal side. Then, the dedicated application receives the transmitted decode set and performs display based on the decode set. As described above, by using the dedicated application and acquiring the history information from the management server 2, it is possible to display on the terminal side. Even if the code is read by other than the dedicated application, the communication with the management server 2 cannot be normally performed, so the history information cannot be displayed.

(Example of processing when linking parent code and child code)
Next, an example of determination processing in the management server 2 after linking the parent code and the child code will be described with reference to FIGS. For example, the process described below is a process useful for preventing fraud. After the parent code and the child code are linked, for example, the time of shipment is conceivable. However, the case processing described below may be performed separately from the shipment.

  FIG. 24 is a flowchart illustrating an example of determination processing in the management server 2 after linking a parent code and a child code. In FIG. 24, after the association between the parent code and the child code is completed, the management server 2 recognizes the weight corresponding to (attached to) the parent code (S1701). For example, the weight of the raw material is associated with the raw material information or the shipping information in FIG. 5C, and is associated with, for example, S205 in FIG.

  Next, the management server 2 recognizes the total weight of the sachet linked to the child code linked to the parent code (S1702). For example, in the example of FIG. 5F, the child codes linked to the parent code A1 are a1 to an. In such a case, the management server 2 is weighted to the child codes a1 to an. The total weight is calculated. Note that the case of the complicated tying state as shown in FIGS. 6A to 6D will be described later.

  The order in which S1701 and S1702 are performed and the flow of the flow are not particularly limited. For example, when the child code corresponding to the sachet is read in the determination process before shipping or before shipping, the determination process starts, and the management server 2 recognizes the parent code corresponding to the child code, The total weight of all the child codes may be recognized by recognizing the weight of the parent code and further recognizing all the child codes associated with the parent code. In any case, if the management server 2 recognizes the weight of the parent code and the total weight of the child code, it does not matter in what flow the recognition is performed.

  Then, the management server 2 determines the type of rice cereal to which the child code is attached based on a predetermined determination criterion (S1703). There are various predetermined determination criteria, but here, the determination criteria shown in FIG. 25 are shown as an example. However, the determination criteria are not limited to those shown in FIG. 25, and can be appropriately changed according to the agricultural products to be used and the actual conditions of the industry.

  FIG. 25 is a table showing criteria for making a determination based on the degree of polished rice, white rice, brown rice, and brown rice. In FIG. 25, the management server 2 determines the type of rice based on the percentage value obtained by dividing the total weight of the sachets linked to the child code by the weight of the parent code. If the percentage value is less than 90%, it means that the rice bran has been scraped off by 10% or more with respect to the brown rice of the large bag with the parent code. It can be determined that it is white rice. Moreover, when the percentage value is 90% or more and less than 92%, it can be determined that the time is 7 minutes. Similarly, when the percentage value is 92% or more and less than 95%, it is determined that the rice is sown for 5 minutes, when it is 95% or more and less than 98%, it is sown for 3 minutes, and when it is 98% or more and 100% or less, it is determined that the rice is brown rice. it can.

  The management server 2 outputs the determination result to the processor side terminal, and confirmation is performed on the processor side terminal (S1704). If there is no error in the determination result, the processor operating the processor side terminal transmits the confirmation result to the management server 2 (S1704). Then, the management server 2 records the determination result in association with the child code (S1705). The management server 2 may record the determination result in association with the parent code. Thereby, a distributor, a consumer, etc. can confirm the classification of the rice which management server 2 judged as information about traceability.

  Here, a case where there is an error in the determination result will be described. For example, if the judgment result is brown rice even though the product enclosed in the sachet is white rice, what does it mean? For example, a large bag of 30 kg brown rice On the other hand, 6 bags of 5kg were produced. However, it is impossible to produce 30 kg of white rice sachet from 30 kg brown rice large bag. In such a case, the large bag originally contains 30 kg brown rice, or depending on the processor Either the padding has been performed at the time of processing, or the yield assumed by the management server 2 is inaccurate.

  With regard to the yield by the management server 2, it is possible to increase the accuracy by repeating the production, and the producer can input the information on the large bag by accurately inputting the raw material information and the shipping information of the large bag. It is also possible to increase the accuracy.

  However, illegally padding the raw material on the processor side results in a problem on the ethics of the processor side. If the system of the present invention is used, the determination result will be recorded as traceability information. If fraudulent padding is performed, a record with brown rice remains even though the shipped small bag is white rice. Therefore, it is virtually impossible for a processor to perform such illegal padding.

  Therefore, it is expected to prevent unauthorized padding by determining the type of product based on the weight of the parent cord and the total weight of the child cord attached to the parent cord, and recording the judgment result. it can.

  If the processor is not cheating, it is preferable to notify the management server 2 of a determination error in step S1704 and change the history information to correct information.

  In addition, although not all cases are fraudulent by the processor, when such a determination error frequently occurs, it is preferable to confirm the rice milling status at the processor by the administrator of the management server.

  In addition, although FIG. 25 described determination of the type of rice cereal, other determination criteria are shown in FIG. FIG. 26 is a diagram for explaining a method of authenticity determination by the management server 2. In FIG. 26, the percentage value is the same as that in FIG. 25, but the type of rice cereal self-declared by the processor is recorded in the management server 2 as “registered contents of child code by processor”. Then, the management server 2 determines that it is true when the registered content matches the type determined by the management server 2, and determines that it is false when it does not match. For example, in the case of FIG. 26, when the percentage value is less than 90%, the management server 2 determines that it is true if a indicates white rice, and determines that it is 白 if a is other than white rice. . Other percentage values can be similarly determined as shown in FIG. Such a determination result may be disclosed as traceability information, but it is not disclosed and is recorded on the management server 2 side. It is possible to take measures such as providing guidance.

  FIG. 27 is a flowchart showing an operation example of display on the consumer terminal side or a terminal capable of browsing history information. On the consumer terminal side, etc., the type of rice registered by the processor is displayed (S1801), and the rice type or authenticity determination result determined by the management server is displayed (S1802). It is also possible to confirm the authenticity of the product. Note that the classification of rice and the result of authenticity judgment are not displayed on the consumer terminal side, but may be recorded as non-public information in the management server 2 as history information, and only those who have viewing authority can view it. You may be able to do it.

  Next, the case of a complicated tying state will be described. As shown in FIG. 6A, when a small bag is made from a plurality of large bags, the total weight associated with the parent cords of all large bags is calculated. Then, the sum of the weights of all the small bags tied to the parent code of all the large bags is calculated. This makes it possible to calculate the total weight of all large bags divided by the total weight of all small bags. Then, based on the calculation result, it is possible to determine the type and authenticity of rice in the same manner as in FIG. 25 and FIG.

  As shown in FIG. 6B, when a sachet is made from a plurality of sachets, the total weight associated with the child cords of all the sachets (raw sachets) is calculated. Then, the sum of the weights of all the sachets (the sachets after commercialization) attached to the sachets of all the sachets as raw materials is calculated. Of course, the weight is recorded in association with the child code of each pouch. This makes it possible to calculate the total weight of all the raw sachets / the total weight of all commercialized sachets. Then, based on the calculation result, it is possible to determine the type and authenticity of rice in the same manner as in FIG. 25 and FIG.

  In the case of FIG. 6C, determination can be performed in the same manner as in FIG. 6A.

  As shown in FIG. 6D, when the raw material bag is a mixture of a large bag and a small bag, the sum of the weights attached to the parent or child code of the large bag or the small bag as all the raw materials is calculated. Then, the sum of the weights of all commercialized sachets associated with the parent or small cord of the large sachets or sachets that are all raw materials is calculated. This makes it possible to calculate the total weight of all large sachets or sachets as raw materials / total weight of all commercialized sachets. Then, based on the calculation result, it is possible to determine the type and authenticity of rice in the same manner as in FIG. 25 and FIG.

  In addition, when a plurality of small bags are made from one large bag, the weight of the single large bag can also be considered as only one large bag to be combined. It can be said that

  In the above description, rice milling has been described. However, it is possible to make a similar determination for refining grains other than rice. When the crop is rice cereals, as a predetermined criterion, the degree of polished rice (white rice, brown rice, sown rice) recognized by the ratio between the weight of the parent cord and the weight of the child cord (in the above example, the percentage value) It is possible to increase the possibility of fraud prevention by using rice.

  Moreover, it is possible to use the above determination not only for rice cereals but also for agricultural products whose weight increases or decreases due to processing. For example, if there are multiple potatoes in a large bag (including a large box, etc.), if the total weight of the sachets is larger than the weight of the large sachets, discard them. There may be fraud, such as potatoes that have been returned. For example, if there are multiple leeks in a large bag, and if there are multiple leeks in a small bag (including small bundles, etc.), the leeks in the small bag will be more than the weight of the large bag. If the total weight of the sachets is large, there may be frauds such as leek that is discarded or returned. In addition, the above-described determination method can be used for agricultural products that can be detected illegally by increasing or decreasing the weight.

  Thus, in the above determination process, the sum of the weights associated with the parent code (which can be conceptualized simply as weight) and the sum of the weights of the child cords associated with the parent code (similarly, It is possible to determine the type, authenticity, etc. of the agricultural product based on a predetermined determination criterion based on the concept of simply expressing it as weight. Taking rice cereal as an example, in other words, the management server determines the type and authenticity of the commercialized rice cereal based on the total weight recorded for the raw rice cereal and the total commercialized weight. It becomes possible to do. The management server can be expected to prevent unauthorized processing by recording the determination result as history information.

  In the above embodiment, crops are used as products. However, the traceability system of the present invention can be used for foods other than crops, and foods received from producers can be subdivided and commercialized. It can be used for all foods sold. The present invention is also useful as a food traceability system.

  The traceability system of the present invention is optimal for history recording of rice cereals, but the target of history recording is not limited to rice cereals.

  Although the present invention has been described in detail above, the above description is merely illustrative of the present invention in all respects and is not intended to limit the scope thereof. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention.

  The present invention relates to a traceability system and can be used industrially.
