However, in the manufacturing process of foods and the like, there are cases where unique identifiers and barcodes cannot be assigned to all foods and intermediate products. For example, after mixing ingredients with a mixer and then putting cut or molded intermediate products sequentially into the next process, give each of these intermediate products identification information such as a unique identifier. Is physically impossible.
For this reason, the prior art described in Patent Documents 1 and 2 and the like may not be applicable to some processes, and there is a problem that accurate history management over all processes is difficult.

  Therefore, the present invention can assign a lot identification ID to each process regardless of the nature of the process, the properties of the intermediate product, and the like. It is an object of the present invention to provide a manufacturing process history management system capable of accurately managing a history.

In order to solve the above-mentioned problem, the invention described in claim 1 is a production in a manufacturing process including the process in which identification information cannot be given to a product (a raw material, an intermediate product, or a finished product) input from a previous process. In a system for managing the history of the product, the system for managing the history of the product by linking the lot of the product by each step with the lot identification ID,

According to the present invention, even in a manufacturing environment having a process in which identification information cannot be given to the product of each process, a lot identification ID can be given based on the operation status of each process, and via this lot identification ID By linking lots between processes, product history information can be accurately managed. In addition, by calculating the operation status as the time lapse of processing in each process, it is possible to obtain history information that is in line with actual movement of foodstuffs and intermediate products.
Furthermore, even when there are a plurality of different previous processes, the operating status of these previous processes is acquired as process performance input, and the product for each previous process is allocated to all subsequent processes at the timing of completing the processes in the subsequent processes. Calculate the amount and issue a lot identification ID switching request, and automatically link the lots between the processes according to the allocated amount, so that the products that have undergone multiple different previous processes are put into the same lot. There is no fear.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 schematically shows a food production process according to this embodiment, and focuses mainly on various data input or assigned in each process, linkage data exchanged between the processes, and the like. It is a thing.

  This manufacturing process includes a receiving process 10 for receiving ingredients as raw materials, a metering process 20 for weighing each ingredient, a blending process 30 for blending each ingredient at a predetermined ratio, and molding the blended ingredients into a predetermined amount and shape. The process includes a molding process 40, an oven process 50 for performing heat treatment such as flying, and a packaging / shipping process 60 for packaging and shipping products in a predetermined unit.

The receiving process 10 includes a receiving input terminal 11, and the receiving date / time, quantity, supplier, quality information, and the like of ingredients as raw materials are input as receiving inspection (acceptance results) information. This acceptance inspection information is constructed as an acceptance inspection record database 12 in cooperation with the lot identification ID 13 assigned for each acceptance lot.
The lot identification ID 13 is also held as a lot output ID 15 that is input to the next weighing step 20.

  Furthermore, a loading record input unit 16 is provided which is an appropriate input terminal equipped with a scanner or reader for reading identifiers and barcodes. The loading record input unit 16 is provided from the receiving process 10 to the next weighing process 20. When each lot of ingredients is input, unique identifiers and barcodes given to the ingredients are read, and these are input as input result information. In the receiving process 10 and the weighing process 20, since the food remains in its original form, it is easy to assign an identifier or a barcode.

When the input result information is input, the input result input unit 16 activates the lot identification ID numbering unit 17 to issue and store the lot identification ID 23 of the next process, and also stores the previous process (in this case, the receiving process 10). The lot input link information 24 for associating the lot output ID 15 with the lot identification ID 23 is generated and stored.
Note that the lot output ID 15 of the previous process and the lot identification ID 23 of the next process are related to each other via the lot input link information 24 so that it is easy to specify the previous process when a plurality of previous processes exist in parallel. In order to clarify the input / output relationship (context relationship) of the process.

  As a numbering method of the lot identification ID 23 by the lot identification ID numbering unit 17, as shown in FIG. 2, when the input result input unit 16 issues a numbering request and issues a number when the food or intermediate product is charged (see FIG. 2). 2), when the input result input unit 16 issues a numbering request and issues a number after a predetermined time has elapsed from the previous time of input (b in FIG. 2), the input result input unit 16 issues a numbering request according to an operator's instruction. There is a case (c in FIG. 2) where a number is issued. Here, the description will be made assuming that the lot identification ID is issued by the numbering request at the time of insertion shown in FIG.

The three modes of the numbering request described above are also applied when the lot identification ID numbering unit 27, 57 issues a lot identification ID by a numbering request from the input result input units 26, 56 in the subsequent process. Is done.
The numbering request (d in FIG. 2) from the previous process and the operation status of the process, which is the fourth mode shown in FIG. 2, is a numbering request by the inter-process link definition calculation units 36 and 46 described later. There will be described later.

In FIG. 1 again, the weighing process 20 includes a weighing input terminal 21, and the weighing result of the food material input from the receiving process 10 is input as weighing information. This weighing information is constructed as a weighing record database 22 in cooperation with the lot identification ID 23 issued by the lot identification ID issuing unit 17.
The lot identification ID 23 is also held as a lot output ID 25 that is input to the next blending step 30.

  Similarly to the above, the input record input unit 26 reads the unique identifiers and bar codes of the ingredients input from the weighing process 20 to the blending process 30 and inputs these as input record information. Then, the numbering request at the time of inputting the ingredients is sent to the lot identification ID numbering unit 27 to cause the lot identification ID 33 to be numbered, and to associate the lot output ID 25 of the previous step (weighing step 20) with the lot identification ID 33. Lot input link information 34 is generated.

The next blending process 30 is provided with a blending data input terminal 31, and various data such as raw material inspection information, sterilization records, and equipment maintenance inspection records and cleaning records input from the weighing process 20 are input as quality control information. Is done. At the same time, record information indicating the operation status of the process is input, and these input data are linked with the lot identification ID 33 to construct the formulation record database 32.
The lot identification ID 33 is also held as a lot output ID 35 that is input to the next molding step 40.

Here, between the blending step 30 and the next molding step 40, and between the molding step 40 and the next oven step 50, due to the nature of each step, identifiers and bars are added to products such as foodstuffs and intermediate products. Identification information such as a code cannot be given. In addition, each process is in a situation where the lead time between the processes varies depending on the required time and operating conditions.
For this reason, the identification information provided in the product is read as in the input record input units 16 and 26 described above, and a lot identification ID numbering request (numbering request a in FIG. 2) is made at the time of entering the next process. The lot identification ID numbering request (numbering request in FIG. 2b) cannot be made after a certain period of time. Accordingly, it is impossible to issue the lot identification ID itself, and it is difficult to associate the lot identification ID with the lot output ID of the previous process.

  Therefore, in the present embodiment, inter-process link definition calculation units 36 and 46 are provided between the blending process 30 and the molding process 40 and between the molding process 40 and the oven process 50, respectively. ) Request lot number ID numbering based on the performance information indicating the operation status of the process, and simultaneously generate lot input link information for associating the lot output ID of the previous process with the lot identification ID of the process. I tried to do it.

That is, as shown in FIG. 2, the inter-process link definition calculation units 36 and 46 in FIG. 1 make a lot identification ID numbering request based on the previous process and the operation status of the process (d in FIG. 2).
As specific configurations of the inter-process link definition calculation units 36 and 46, the elapsed time (lead time) calculation means d1 of the previous process, the process connected to the previous process, and other processes (both are the subsequent processes). Operating result calculation means d2, lot identification ID number request / switch request means d3, and lot input link information generation means d4.
In the inter-process link definition calculating units 36 and 46, based on the previous process, the operation status of the process, and the elapsed time corresponding to the lead time of the previous process, a lot identification ID numbering request or switching request, a lot input link Generate information. Further, when the processing amount of the process and the other process calculated from the operation status (operation performance) of the process and the other process connected to the previous process matches the processing amount of the previous process, a request for switching the lot identification ID is issued.

Next, the operation of the inter-process link definition calculation unit (for example, the inter-process link definition calculation unit 36 between the blending process 30 and the molding process 40) will be described in detail below.
First, FIG. 3 shows a manufacturing process in which one blending process 30, three molding processes 40A, 40B, and 40C and oven processes 50A, 50B, and 50C are manufactured and A product, B product, and C product are manufactured in parallel. It is explanatory drawing. As shown in FIG. 1, the process results input also exists in the oven processes 50A, 50B, and 50C, but here, emphasis is placed on the processing between the blending process 30 and the molding processes 40A, 40B, and 40C. For the purpose of explanation, the process result input in the oven processes 50A, 50B, and 50C is ignored.

FIG. 4 is an explanatory diagram when the blending step 30 is executed by the mixer 30M, and is substantially the same as FIG.
The operation of the inter-process link definition calculation unit 36 will be described with reference to the flowchart of FIG. Note that FIG. 1 and FIG. 2 are also referred to as necessary.

First, when a process result input event in the blending process 30 occurs, process I in FIG. 5 is started. In the process I, first, the operation status of the blending process 30 at the time of the process result input is acquired, the elapsed time from the start of the operation is calculated and compared with the preset lead time, and the elapsed time becomes equal to the lead time Wait (S1 to S3 in FIG. 5). This process is executed by the elapsed time (lead time) calculating means d1 in FIG.
Here, if the plurality of ingredients are charged into the mixer 30M at the time t1 in FIG. 4 and the operation of the blending step 30 is started, the following molding steps 40A, 40B, and 40C are started from the time t1. Time to start. Time t2 indicates the input time in the next lot of the blending process 30.

  When the elapsed time becomes equal to the lead time, the blending amount by the mixer 30M is calculated (S4). This calculation means corresponds to the pre-process throughput calculation means in the claims. Thereafter, a lead time calculation completion event is issued (S5). This lead time calculation completion event is stored in the lead time event buffer (S6).

  When the event is stored in the lead time event buffer, the process II is started and the event waiting state is released (S7). Next, it is determined whether or not the process (molding process) is in the initial stage of operation (initial start-up) (S8). A numbering request is made to the numbering part 37 (S9, S10), and the lot identification ID 43 is numbered. The numbering request is executed by the lot identification ID numbering request / switch requesting means d3 in FIG. At the same time, the lot input link information generating means d4 in FIG. 2 generates lot input link information 44 for associating the lot identification ID 43 with the lot output ID 25 in the blending step 30.

Then, the operation status of the other process leading to the blending process 30 is acquired (S11). Here, as shown in FIGS. 3 and 4, there are three molding processes (molding processes 40A, 40B, and 40C) that lead to the blending process 30, and if the molding process 40A is the above-described process, other processes are possible. The operation status of the molding steps 40B and 40C will be acquired.
In addition, on the right side of FIG. 5, all the molding processes 40A, 40B, and 40C are illustrated for convenience as other processes for acquiring the operation status in step S11. The operation status of other processes (40B, 40C) obtained by removing the process (for example, 40A) from 40B, 40C is acquired.
Here, in each molding process 40A, 40B, 40C, as shown in FIG. 5, process III is activated by the result input event of each process, and the respective operation statuses are the inter-process link definition calculation unit 36 and molding record in FIG. It is stored in the database 42.

When the operation status of the other process is acquired, the total processing amount of the process and the other process from the start of the lot is calculated (S12). This calculation means corresponds to the post-process total processing amount calculation means in the claims. Then, it is determined whether or not the total processing amount is equal to the blending amount in blending step 30 calculated in step S4 (S13). That is, the processes in steps S11 to S13 are repeated until the total processing amount becomes equal to the blending amount in the blending step 30, and when both become equal, the provision amount for all the molding steps 40A, 40B, and 40C is calculated (S14). ).
In calculating the total processing amount, the operation result calculation unit d2 in FIG. 2 calculates the operation result based on the operation status of the process and other processes.

When the allocation amount is calculated, it is determined that the lot has been completed, and a lot identification ID switching request is issued in order to issue a new lot identification ID (S15). This processing is executed by the lot identification ID number request / switch request means d3 in FIG. Thereafter, the lot identification ID numbering unit 37 in FIG. 1 is in a state where a new lot identification ID can be issued.
The lot identification ID 43 in the molding process 40 of FIG. 1 is issued and lot input link information 44 is generated by the operation of the inter-process link definition calculation unit 36 described above.

The molding process 40 includes a molding data input terminal 41, and various data such as sterilization records, equipment maintenance inspection records, and cleaning records are input as quality control information. Further, as described above, the record information indicating the operation status of the process is input to the inter-process link definition calculation unit 36 and also input to the inter-process link definition calculation unit 46 between the next oven process 50, Further, the molding record database 42 is constructed in cooperation with the lot identification ID 43.
The lot identification ID 43 is also held as a lot output ID 45 that is input to the next oven process 50.
The operation of the inter-process link definition calculation unit 46 is substantially the same as that of the above-described inter-process link definition calculation unit 36, and only the steps before and after each are different, and thus description thereof is omitted.

The oven process 50 is performed by an oven data input terminal 51 for inputting temperature, sterilization record, equipment maintenance inspection record, cleaning record, etc. as quality control information, an oven record database 52, and a lot identification ID numbering unit 47. A lot identification ID 53 to be assigned, lot input link information 54, and a lot output ID 55.
Further, the packaging / shipping process 60 includes a packaging / shipping data input terminal 61 for inputting sampling inspection information, weight inspection information, shipping records, etc. as quality control information, a packaging / shipping record database 62, and a lot identification ID numbering section. The lot identification ID 63 issued by 57, the lot input link information 64 generated by the input result input unit 56, and the lot output ID 65 are included.
The operation of each of these processes 50 and 60 can be easily analogized by the operations of the input record input units 16 and 26, the inter-process link periodic calculation unit 36, etc. from the receiving process 10 to the molding process 40 described above. Therefore, the description is omitted.

  Next, FIG. 6 is a schematic system configuration diagram of an embodiment of the present invention. In this example, the history management server 100 composed of a high-speed and large-capacity computer that manages the history of ingredients and intermediate products is described above. It is configured as a client-server system having terminals 11, 21, 31, 41, 51, 61 in each process.

The history management server 100 includes a lot identification ID numbering unit 110, an input result input unit 120, and an inter-process link definition calculation unit 130, which include the lot identification ID numbering unit 17 of each process in FIG. 27, 37, 47, and 57, the input results input units 16, 26, and 56, and the inter-process link definition calculation units 36 and 46, respectively.
The database 200 is an integration of the various databases 12, 22, 3, 42, 52, and 62 shown in FIG. 1. Although not shown, the database 200 also stores lot input link information for each process. ing.
The history management server 100 further includes an input device 300 such as a keyboard and an output device 400 such as a display for displaying history search conditions and search results.

With reference to the configuration of FIG. 6, the operation when searching for the history of foodstuffs, intermediate products, and finished products in the manufacturing process shown in FIG. FIG. 7 is a display screen of a display as the output device 400.
In the present embodiment, as described above, in the series of manufacturing processes, the lot identification ID of the ingredients and intermediate products in each process is issued by the input record input unit 120 or the inter-process link definition calculation unit 130, Lot input link information is generated. In each process, various types of information including quality control information associated with these lot identification IDs are constructed as the database 200.

  For this reason, for example, a history analysis screen as shown in FIG. 7 is generated by the history management server 100, and the history management server 100 performs the lot identification ID or the like under predetermined search conditions (input process, output process, management items, etc.). By referring to the database 200 using the lot input link information as a key, it is possible to search the history of foodstuffs, intermediate products, and finished products while linking lots between processes.

  The history analysis screen of FIG. 7 includes an area 401 for selecting a desired input process as a search condition, an area 402 for displaying various management items in the selected input process and inputting desired information, and a search condition. An area 403 for selecting a desired output process, an area 404 for displaying various management items in the selected output process to check desired information, and a search start key 405 after inputting a search condition are executed. And an area 406 for displaying search results.

In the example of FIG. 7, an acceptance date and a supplier name are specified for the acceptance process that is the input process, and what kind of product name, production date lot, and transportation in the shipping process that is the output process is the food that meets these conditions. As a result of searching for whether the product has been shipped, so-called trace forward is executed, and as shown in area 406, the corresponding product name, production date lot, and transportation means are displayed in a list.
Needless to say, the management items displayed in the areas 402 and 404 differ depending on the process selected in the areas 401 and 403.

As described above, in this embodiment, it is possible to trace the history of ingredients, intermediate products, and finished products from the upstream process to the downstream process (trace forward) or from the downstream process to the upstream process (trace back). It is possible to efficiently perform tracking when a foreign substance is mixed in, and investigation of the cause when a defective product occurs.
In particular, it is not possible to give a unique identifier or barcode to the product, such as between the blending process 30 and the molding process 40, between the molding process 40 and the oven process 50, and the time required for each process. Even in a situation where the lead time between processes varies depending on the operating status and the like, accurate and continuous history management becomes possible by giving a lot identification ID or the like in consideration of the operating results.

Next, FIG. 8 is an explanatory view of the main part of the manufacturing process in another embodiment of the present invention.
In this embodiment, there are two blending steps 30A and 30B as a pre-step of the molding steps 40A, 40B and 40C.

  In the present embodiment, although not shown, an inter-process link definition calculation unit is provided between each blending process 30A, 30B and each molding process 40A, 40B, 40C, and the operation status of the blending processes 30A, 30B is determined as a process. The inter-process link definition calculation unit is acquired as a result input, and the processing amount for each of the blending processes 30A and 30B is completed at the timing when the process (molding) is completed by the molding process. The allocation amount is calculated, and the inter-process link definition calculation unit issues a lot identification ID switching request.

In the lower part of FIG. 8, (a) the timing at which the intermediate product blended in the blending step 30A is completed in each molding step 40A, 40B, 40C, (b) the intermediate product blended in the blending step 30B is each molding step 40A, The timing at which the processing is completed at 40B and 40C, and (c) the lot switching timing at the molding steps 40A, 40B and 40C (timing for requesting switching of the lot identification ID) are shown.
As is apparent from this figure, (c) the lot switching timing of the molding steps 40A, 40B, and 40C is the logical sum of the timings of (a) and (b), and was blended by either the blending step 30A or 30B. When the intermediate product has been processed by the molding process, the provision amount for all the molding processes 40A, 40B, and 40C is calculated, and the lots are switched.
This eliminates the possibility that products (intermediate products) that have undergone different previous processes, for example, the blending processes 30A and 30B, will be put into the same lot.

  In the above-described embodiment, the case where the present invention is applied to a food manufacturing process has been described. However, the application field of the present invention is not limited to a food manufacturing process, and a blending process or molding in which it is difficult to provide identification information. It can be applied to the manufacturing process of various products (chemical products, pharmaceuticals, etc.) that require processes.
