However, this is only an example, and the RFID is used in any of a series of processes in which the information display member 10 is used. A reader / writer or a two-dimensional code reader may not be provided.

Next, the flow of processes performed using the process management system 1 according to the reference example will be described.
First, the information display member 10 is issued by the issuing system 30 (issued as a management plate for managing a series of processes). In the issuing system 30, various management data are written to the RFID tag 11 by the RFID reader / writer 35. The management data written to the RFID tag 11 may be information used in a series of processes. For example, information such as process name, process number, and process content for each process can be stored. In addition, the name and part number of the part in which the information display member 10 is used, the name and product number of the product to be used for the part, or the name of the factory in which the information display member 10 is used and the target part are shipped. The factory name can be stored. In addition, visible information (character information and graphic information) related to process management is printed on the printing unit of the information display member 10 by the printing device 31. As the character information related to the process management, for example, the name and part number of a part in which the information display member 10 is used, the name and product number of a product to be used for the part, or the information display member 10 is used. The factory name, the name of the factory to which the target part is shipped, and the like can be mentioned. As the graphic information, for example, such information or a bar code or a two-dimensional code in which a part of the management data stored in the RFID tag 11 is coded. Can be mentioned.

The information display member 10 thus issued is attached to, for example, a box (passage box 15) that accommodates parts. Note that the step of attaching the information display member 10 to the through box 15 may be performed automatically by a robot or may be performed manually. The information display member 10 attached to the pass box 15 is read or written in each process (process A, B, final process, etc. shown in FIG. 1) and used in various ways.
The RFID reader / writers 41, 42, and 43 correspond to an example of “reading unit” and function to read management data written in the RFID tag 11 (storage unit). Further, when some management data is written by the RFID reader / writers 41, 42, 43, the RFID reader / writers 41, 42, 43 also function as “management data writing means”.

  Then, after the final process (for example, a part shipping process) in which the information display member 10 is used is completed, the information display member 10 is removed from the box 15. This removal process may be performed automatically by a robot or the like, or may be performed by human work. The information display member 10 thus removed is transported to the reuse process each time or collectively.

  The reuse process is performed, for example, according to the flow shown in FIG. First, a process of checking an error of the collected information display member 10 is performed (S1). This process is performed by the information processing apparatus 21 and the RFID reader / writer 23, and a process for confirming whether or not the collected information display member 10 has a problem that causes a problem of reuse is performed. Various methods for checking the error that occurred in the information display member 10 can be considered as an error check method. Here, the RFID reader / writer 23 tries to read the RFID tag 11 and the data in the RFID tag 11 is normally restored. It is confirmed whether or not the information display member 10 is normal by checking whether or not it can be read. The data configuration of the RFID tag 11 is, for example, as shown in FIG. 4. In S1, is it possible to read ID information and usage history information (usage count data, cleaning count data, etc., which will be described later) unique to the RFID tag 11? If any information cannot be read, it is determined as an error.

  When an error is confirmed in the information display member 10 in the process of S1, the process proceeds to Yes in the determination of S2, and the cleaning process of S5 is performed. On the other hand, if no error is confirmed in the information display member 10 in the step S1, the process proceeds to No in the determination in S2, and a step of confirming whether or not the information display member 10 is a cleaning target is performed (S3). ). This process is performed by the information processing apparatus 21 and the RFID reader / writer 23, and it is determined whether or not the information display member 10 is a cleaning target. Specifically, a target that has been used more than a predetermined number of times since the cleaning process has been performed (that is, one that has been issued more than a predetermined number of times) is a target to be cleaned. It is confirmed whether it corresponds to the target to be cleaned.

In the step S3, specifically, the cleaning target selection process as shown in FIG. 6 is performed. In this cleaning object selection process, first, a process of reading the number of times the information display member 10 to be reused after cleaning is used (S101). As shown in FIG. 4, the RFID tag 11 of the information display member 10 used in this reference example stores data on the number of times used after cleaning (data on the number of times used after cleaning). In S101, the data on the number of times used after cleaning is stored. Is read, the number of times the information display member 10 is used after cleaning is grasped. Further, a previously stored threshold value (threshold value for comparison of the number of times of use after cleaning) is read (S102), and it is determined whether or not the number of times of use after cleaning confirmed in S101 has reached the threshold value (S103). Note that the threshold value to be compared with the number of times of use after cleaning may be stored in the information processing apparatus 21 in advance, or may be stored in the RFID tag 11 as unique information. If the number of uses after cleaning has reached the threshold, the information display member 10 is set as a cleaning target (S104). On the other hand, when the number of uses after cleaning has not reached the threshold, the information display member 10 is set as a non-cleaning target (S105). Setting data as to whether or not to be cleaned may be temporarily stored in the RFID tag 11 of the information display member 10 or may be stored in the information processing apparatus 21.

  If it is determined in S2 that there is an error, or if it is determined in S4 that the object is to be cleaned, a cleaning process is performed (S5). This cleaning process is a process performed by the cleaning device 27 and the information processing device 21. First, the information display member 10 is cleaned by the cleaning device 27. And after washing | cleaning, the process which resets the frequency | count of use after washing | cleaning and the process which updates the frequency | count of washing | cleaning are also performed collectively. Specifically, new post-cleaning use count data in which the post-cleaning use count is 0, and new cleaning count data obtained by adding 1 to the cleaning count are generated, and the contents stored in the RFID tag 11 are updated. .

On the other hand, when it is not determined as a cleaning target in S4 (that is, when the number of uses after cleaning does not reach the threshold value), the information display member 10 is not cleaned and the process proceeds to S8.
In this reference example , the information processing device 21 and the cleaning device 27 correspond to an example of “cleaning means”, and the information display member 10 is cleaned under predetermined conditions when the information display member 10 is reused. Function.
The information processing apparatus 21 corresponds to an example of a “selection unit”, and functions to perform predetermined selection when the information display member 10 is reused based on use history information. More specifically, it corresponds to an example of “cleaning target selecting means”, and functions to select whether or not the information display member 10 is a cleaning target based on the use count data after cleaning.

  After the cleaning process of S5 is completed, it is confirmed whether or not the information display member 10 is to be discarded (S6). In this confirmation step, it is confirmed whether or not the information display member 10 is an error medium, and whether or not the total number of times the information display member 10 has been used has reached a predetermined threshold value. It is targeted.

In the process of S6, specifically, the discard target selection process as shown in FIG. 7 is performed.
In the discard target selection process, first, a process for confirming unique information and usage history information about the information display member 10 to be reused is performed (S110). As shown in FIG. 4, the RFID tag 11 stores ID data, manufacturer data, model number data, and the like as unique information. In S110, any (for example, ID data) or all of these unique information is properly stored. Check if it can be read. In addition, usage history information includes post-cleaning usage count data, total usage count data, and cleaning count data, and whether any of these (for example, total usage count data) or all of them can be read normally. Confirm. If the unique information and the usage history information are normally confirmed in S110, the process proceeds to Yes in S111, and the total usage count of the information display member 10 is determined based on the total usage count data stored in the RFID tag 11. It is determined whether or not a threshold value (threshold value for comparison of the total number of times of use) has been reached (S112). Note that the threshold for comparison of the total number of times of use may be stored in the information processing apparatus 21 in advance, or may be stored in the RFID tag 11 as unique information. If the total number of uses has not reached the threshold, the process proceeds to No in S112, and the information display member 10 is set as a non-discard target (S113).

  When the process proceeds to No in S111 (when the unique information and the use history information are not confirmed) or when the process proceeds to Yes in S112 (when the total number of use reaches the threshold value), the information display member 10 is set as a disposal target. Set (S114). Setting data as to whether or not to be discarded may be temporarily stored in the RFID tag 11 of the information display member 10 or may be stored in the information processing apparatus 21.

When the information display member 10 is set to be discarded in S6, the process proceeds to Yes in S7, and a discarding process is performed (S11). The discarding process of S11 may be any process as long as some kind of treatment for discarding the information display member 10 is performed, and may be a process of collecting the information display member 10 in a predetermined disposal space. Or a step of attaching a predetermined disposal mark.
In the present reference example , the information processing device 21 corresponds to an example of “discarding target selection means”, and whether or not to discard the information display member 10 based on usage history information (specifically, total usage count data). Functions to perform sorting.

If it is determined in S7 that it is not a target for disposal or if it is determined in S4 that it is not a target for cleaning, the visible information (character information and graphic information) written on the information display member 10 is deleted (S8). This process is performed by the information processing device 21 and the erasing device 25, and characters written on the surface portion (printing portion) of the sheet material 12 by the erasing device 25 that has received a command from the information processing device 21. Information and graphic information are deleted.
In this reference example , the erasing device 25 and the information processing device 21 correspond to an example of “visible information erasing means”.

Management data is also erased (S9). This process is performed by the information processing apparatus 21 and the RFID reader / writer 23, and the management data stored in the RFID tag 11 is deleted by the RFID reader / writer 23 that has received a command from the information processing apparatus 21. In the process of S9, the management data is selectively deleted. Specific information such as ID information, manufacturer data, model number data, usage history information such as post-cleaning usage count data, total usage count data, cleaning count data, etc. It remains without being erased.
In this reference example , the RFID reader / writer 23 and the information processing apparatus 21 correspond to an example of “data erasing means”, and a part of data stored in the RFID tag 11 (storage means) (specifically, total This function functions to delete management data excluding use history information such as use count data, use count data after cleaning, and cleaning count data.

As described above, in the process management system 1 according to the present reference example , the visible information (character information and graphic information) written on the surface portion (printing portion) of the sheet material 12 is erased after the series of steps is completed, and the RFID Since the management data stored in the tag 11 is erased, the information display member 10 can be reused without the previous process management information remaining.

Thereafter, the number of uses is updated (S10). This process is performed by the information processing apparatus 21 and the RFID reader / writer 23. The RFID reader / writer 23 that has received a command from the information processing apparatus 21 rewrites the total use count data stored in the RFID tag 11. Is called. Specifically, new total use count data is generated by adding 1 to the total use count before update, and this data is written to the RFID tag 11 by the RFID reader / writer 23.
In this reference example , the RFID reader / writer 23 and the information processing apparatus 21 correspond to an example of “usage history information writing unit”, and the usage history information of the information display member 10 is written to the RFID tag 11 (storage unit). To work. Specifically, the total number of uses (that is, the number of issues) of the information display member 10 and the number of uses after cleaning are written in the RFID tag 11 as “use history information”.

According to the configuration of this reference example , for example, the following effects can be obtained.
In the process management system 1 according to this reference example , when the information display member 10 is reused, the information display member 10 is washed under a predetermined condition, and therefore, contamination due to reuse can be suppressed as much as possible. Furthermore, the usage history information of the information display member 10 is configured to be written in the RFID tag 11, and when reusing, a predetermined sorting process is performed based on the written usage history information. Therefore, when the information display member 10 is reused, appropriate selection according to the use history can be performed, and the information display member 10 can be effectively used while considering the use history.

  In addition, as the “usage history information”, the number of times the information display member 10 is used (that is, the number of times it is issued) is written. Since the number of uses (issue number) of the information display member 10 is extremely related to the contamination or deterioration that occurs in the information display member 10, if the number of uses of the information display member 10 is used as a selection index when reusing, the contamination And sorting with appropriate consideration of the deterioration status.

  Further, when the information display member 10 is reused, the selection as to whether or not the information display member 10 is to be cleaned is performed based on the use history information (specifically, the number of uses after cleaning). Yes. In this way, it is possible to specifically determine whether or not to clean each information display member that is to be reused, and it is possible to appropriately clean each information display member 10 in consideration of the use history.

  Further, the selection of whether or not to discard the information display member 10 is performed based on the use history information (specifically, the total number of uses). If it does in this way, it can judge satisfactorily based on the use history whether the information display member 10 was used to such an extent that it should be discarded, and it becomes possible to sort a candidate for disposal appropriately.

First Embodiment
Next, a first embodiment will be described. The first embodiment, only in that as in FIG. 8 is different from the reference example in place of 6 specific contents of the confirmation process to be cleaned (S3) shown in FIG. 5, otherwise similar to the Reference Example It is. Accordingly, different contents will be described with emphasis, and FIGS. 1 to 5, 7, etc., which are the same as those in the reference example , will be referred to as appropriate, and detailed description thereof will be omitted.

  In this embodiment, the cleaning target selection process is performed as shown in FIG. In this process, first, a process of reading the number of uses after cleaning of the information display member 10 to be reused is performed (S201). The process of S201 is the same as S101 of FIG. Furthermore, the process which reads the total use frequency of the information display member 10 is performed (S202). As shown in FIG. 4, the total use count data is stored in the RFID tag 11 of the information display member 10 used in the present embodiment. In S202, the total use count data is read to read the total use count data. Know the number of times. Further, a threshold value corresponding to the total number of uses (threshold value to be compared with the number of uses after cleaning) is read (S203). In the present embodiment, as shown in FIG. 9, the threshold value X to be compared with the number of uses after cleaning is associated with the total use number R and stored in the memory (ROM, HDD, etc .: not shown) of the information processing apparatus 21. In S203, the threshold corresponding to the total number of times used acquired in S202 is read. The threshold value X is set to be smaller as the total number of uses increases (that is, X1> X2> X3> X4> X5).

  Then, it is determined whether or not the use count after cleaning confirmed in S201 has reached the threshold value acquired in S203 (S204). If the number of uses after cleaning has reached the threshold, the information display member 10 is set as a cleaning target (S205). On the other hand, when the number of uses after cleaning has not reached the threshold, the information display member 10 is set as a non-cleaning target (S206).

  In the present embodiment, the information processing apparatus 21 corresponds to an example of “sorting unit” and “cleaning target sorting unit”. The information processing device 21 corresponds to an example of “cleaning interval setting means”, sets the cleaning interval of the information display member 10, and performs cleaning according to the number of times the information display member 10 is issued (specifically, the total number of uses). It functions to change the interval.

  In this embodiment, cleaning interval setting means for setting the cleaning interval of the information display member 10 is provided, and the cleaning interval is changed according to the number of times of issuing the information display member 10 (specifically, the total number of times of use). A cleaning interval corresponding to the number of times can be set, and cleaning can be performed at a more appropriate time based on the cleaning interval and usage history information.

  In particular, in the present embodiment, the threshold value is set to a smaller value as the total number of uses increases, so that cleaning is performed more frequently as the use proceeds. In this way, it is possible to suppress the deterioration by increasing the cleaning interval at the initial stage where the remaining dirt is not noticeable (the stage where the total number of times of use is low). For many stages), it is possible to effectively suppress dirt by frequently washing.

[ Second Embodiment]
Next, a second embodiment will be described. The second embodiment is different from the reference example only in that the specific content of the confirmation step (S3 or S6) shown in FIG. 5 is changed, and is otherwise the same as the reference example . Therefore, points different from the reference example will be described mainly, and detailed description of points that are the same as the reference example will be omitted.

First, an example of this embodiment will be described with reference to FIG. This example differs from the reference example in that the discard target confirmation step (S6) shown in FIG. 5 is changed to that shown in FIG. 10 instead of FIG. 7, and the other FIGS. 1 to 6 are the same as the reference example . It is.

  In the discard target selection process according to the present embodiment, first, a process of reading the total number of uses for the information display member 10 to be reused is performed (S301). In S301, the total usage count data (FIG. 4) stored in the RFID tag 11 is confirmed, and the current total usage count of the information display member 10 is acquired. Furthermore, the process which reads the manufacturer of the information display member 10 is performed (S302). As shown in FIG. 4, the RFID tag 11 of the information display member 10 used in the present embodiment stores manufacturer data that can specify the manufacturer name of the information display member 10, and this manufacturer data is stored in S302. By reading, the manufacturer of the information display member 10 to be reused is grasped. Further, a threshold value corresponding to the manufacturer (threshold value serving as a reference for determining whether or not to discard) is read (S303). In this embodiment, for example, as shown in FIG. 12A, a threshold value Y to be compared with the total number of times of use is associated with a manufacturer and stored in a memory (ROM, HDD, etc .: not shown) of the information processing apparatus 21. In step S303, the threshold value corresponding to the manufacturer acquired in step S302 is read. For example, if the manufacturer of the information display member 10 to be reused is manufacturer A, the corresponding threshold value Y1 is read out.

Then, it is determined whether or not the total use count acquired in S301 has reached the threshold acquired in S303 (S304). If the total use count has reached the threshold, the information display member 10 is set as a discard target (S305). On the other hand, when the total number of uses has not reached the threshold, the information display member 10 is set as a non-discard target (S306).
In this embodiment as well, the information processing apparatus 21 corresponds to an example of “sorting means” and “discarding target sorting means”, and functions to perform sorting processing based on manufacturer main information and usage history information. Yes.

  When the sorting process is performed based on the main information of the manufacturer that manufactured the information display member 10 to be reused and the usage history information as in the present embodiment, not only the usage history but also the information display member. The sorting process can be performed in consideration of the maker that manufactured 10. For example, for the information display member of a manufacturer that is not easily contaminated, the total number of times of use is set (that is, the threshold value is set large), and for the manufacturer that is easily contaminated, the total number of times of use is set (ie, the threshold value is set to be small) It becomes possible to do. Alternatively, set the total number of uses for the information display member of the manufacturer that provides the product with low durability (set the threshold value small), and set the total number of use for the information display member of the manufacturer that provides the product with high durability. It is also possible to set many (set the threshold value large).

Moreover, you may make it like FIG. In this example, the cleaning target confirmation step (S3) shown in FIG. 5, unlike the reference example that was shown in FIG. 11 in place of 6, FIGS. 1 to 5 the other, the reference about 7 Same as example .

  In the process of FIG. 11, first, a process of reading the number of uses after cleaning of the information display member 10 to be reused is performed (S311). The process of S311 is the same as S101 of FIG. Furthermore, the process which reads the model number data of the information display member 10 is performed (S312). As shown in FIG. 4, the RFID tag 11 of the information display member 10 used in the present embodiment stores model number data that can identify the model number of the information display member 10, and in S312, by reading this model number data, The model number of the information display member 10 is grasped. Further, a threshold corresponding to the acquired model number (threshold serving as a reference for determining whether or not to be cleaned) is read (S313). In this case, as shown in FIG. 12B, the model number and the threshold value Z (threshold value for determining whether or not to be cleaned for each model number) are associated with each other and the memory (ROM, HDD, etc.) of the information processing apparatus 21 is associated. : Not shown), and the threshold corresponding to the model number acquired in S312 is read in S313. For example, if the model number of the information display member 10 to be reused is model number A, the corresponding threshold value Z1 is read out.

Then, it is determined whether or not the number of post-cleaning uses confirmed in S311 has reached the threshold acquired in S313 (S314). If the use count after cleaning has reached the threshold value, the information display member 10 is set as a cleaning target (S315). On the other hand, if the number of uses after cleaning does not reach the threshold value, the information display member 10 is set as a non-cleaning target (S316).
In this example, the information processing apparatus 21 corresponds to an example of “sorting means” and “cleaning target sorting means”, and functions to perform sorting processing based on the model number information and the usage history information of the information display member 10. .

  As shown in FIG. 11, when the sorting process is performed based on the model number information and the usage history information of the information display member 10 to be reused, the model number of the information display member 10 is considered in addition to the usage history. The sorting process can be performed. For example, the cleaning interval is set long (that is, the threshold value is set large) for a model number that is difficult to accumulate dirt, and the cleaning interval is set short (that is, the threshold value is set small) for a model number that easily accumulates dirt. It becomes possible. Alternatively, it is possible to set a longer cleaning interval (set a larger threshold) for a model with low durability and set a shorter cleaning interval (set a lower threshold) for a model with high durability.

[ Third Embodiment]
Next, a third embodiment will be described. The third embodiment is different from the reference example only in that the specific contents of the discard target confirmation step (S6) shown in FIG. 5 are as shown in FIG. 13 instead of FIG. 7, and otherwise the same as the reference example. It is. Accordingly, different contents will be described with emphasis, and FIGS. 1 to 6 and the like that are the same as the reference example will be referred to as appropriate, and detailed description thereof will be omitted.

  In the present embodiment, the discard target sorting process is performed as shown in FIG. Even in the discard target selection process, first, a process for confirming the unique information and the use history information about the information display member 10 to be reused is performed (S401). Note that the processing of S401 is the same as that of S110. If the unique information and the usage history information are normally confirmed in S401, the process proceeds to Yes in S402, and the threshold value corresponding to the model number of the information display member 10 (the threshold value that serves as a reference for discarding) is set. read. In this case, the threshold value may be set with the same data configuration as in FIG. 12B. For example, the model number A can be set to the threshold value M1, and the model number B can be set to the threshold value M1.

  Then, it is determined whether or not the total use count of the information display member 10 has reached the threshold value acquired in S403 (S404). The total usage count is grasped by the total usage count data in FIG. 4. If the total usage count does not reach the threshold acquired in S403, the process proceeds to No in S404, and the information display member 10 Are set as non-discard targets (S405). On the other hand, when the process proceeds to No in S402 (when the unique information and the use history information are not normally confirmed), or when the process proceeds to Yes in S404 (when the total number of use reaches the threshold value), the information display member 10 Is set to be discarded (S406). Setting data as to whether or not to be discarded may be temporarily stored in the RFID tag 11 of the information display member 10 or may be stored in the information processing apparatus 21.

  As shown in FIG. 13, when the disposal target is selected based on the model number information and usage history information of the information display member 10 to be reused, the disposal target is considered in consideration of the model number of the information display member 10. Can be selected. For example, it is possible to set a low threshold value for a model number that is likely to deteriorate and discard it at an early stage, and set a high threshold value for a model number that is difficult to deteriorate, and then discard it after using a relatively large amount.

  In the example of FIG. 13, a threshold value that serves as a disposal reference is set in association with the model number. However, a threshold value that serves as a disposal reference may be set in association with the manufacturer that manufactured the information display member 10. In this case, the threshold value may be set with the same data configuration as in FIG. 12A. For example, the threshold value N1 for the manufacturer A and the threshold value N2 for the manufacturer B can be set. In this way, for example, a manufacturer that provides products that are prone to deterioration is set to a low threshold and discarded at an early stage, and a manufacturer that provides products that are difficult to deteriorate is set to a high threshold and compared. It is possible to dispose of the product after using it as much as possible.

[ Fourth Embodiment]
Next, a fourth embodiment will be described. This embodiment is different from the reference example only in the reuse process, and is otherwise the same as the reference example . The reuse process is different from FIG. 5 in that the order of each process performed in FIG. 5 is changed and a use prohibition process is provided.

  In the reuse process of the present embodiment, first, a visible information (character information and graphic information) erasing process (S501) and a management data erasing process (S502) are performed. The process of S501 is the same as S8 of FIG. 5, and character information and graphic information written on the surface part (printing part) of the information display member 10 are erased by this process. Further, the process of S502 is the same as S9, and the management data stored in the RFID tag 11 is deleted by this process.

  Further, an error check similar to S1 (FIG. 5) is performed (S503). If no error is confirmed in S503, the process proceeds to No in S504, and a cleaning target confirmation process is performed (S505). The process of S505 is the same as S3 of FIG. 5, and may be performed as illustrated in FIG. 6, or may be performed as illustrated in FIG. 8, FIG. 10, or FIG. If it is not set as a cleaning target in this cleaning target confirmation step (S505), the process proceeds to No in S506 and the information display member 10 is reused.

  On the other hand, when the process proceeds to Yes at S504 (when an error is confirmed at S503) or when the process proceeds to Yes at S506 (when the object to be cleaned is set at S505), a cleaning process is performed (S507). The cleaning process in S507 is the same as S5 in FIG. Thereafter, the number of uses is updated (S508). The process of S508 is the same as S10 of FIG. 5, and the total use count data is updated. Further, a discard target confirmation step similar to S6 (FIG. 5) is performed (S509). The discard target selection process may be a method as shown in FIG. 7 or a method as shown in FIG. If the information display member 10 is not a target for disposal, the process proceeds to No in S510, the reuse process is terminated, and the information display member 10 is reused.

  On the other hand, if it is determined in S510 that the object is to be discarded, the process proceeds to S511 to perform a use prohibition process. This use prohibition step is a step of performing some measure for prohibiting the use of the information display member 10. For example, a mark or character indicating use prohibition is written on the surface portion (printing portion) of the information display member 10. Examples are given. If it does in this way, it will become possible to confirm easily visually whether the information display member 10 should be prohibited, and it can prevent effectively that such a medium is reused accidentally now.

  Alternatively, the RFID tag 11 may store data indicating that use is prohibited (use prohibited data). In this case, the information display member 10 in which the use prohibition data is stored in the error confirmation process in S503 is also determined as an error medium, or the use prohibition data is stored in the issuing system 30 (FIGS. 1 and 2). Is not issued, it will not be mixed once determined to be discarded.

  In addition, a predetermined alarm may be issued when it is set as a discard target in S509 (for example, when usage history information is unreadable). In this way, the operator can quickly grasp the malfunction of the information display member 10, and a smoother system can be constructed.

  In the present embodiment, the information processing apparatus 21 corresponds to “confirmation means” and functions to confirm whether or not the usage history information can be read. The information processing device 21 and a printing device (or RFID reader / writer) (not shown) correspond to an example of “use prohibition unit”, and function to prohibit use of the information display member 10 when use history information cannot be read. To do. The information processing device 21 and a display unit or buzzer (not shown) correspond to an example of “alarm means”, and function to issue an alarm when the usage history information is unreadable.

  In the present embodiment, since the use prohibition process is performed when the use history information is unreadable, it is difficult for information display members having malfunctions to easily occur to be mixed, and the system can be operated more smoothly. Become.

[ Fifth Embodiment]
Next, a fifth embodiment will be described. This embodiment, the data structure of the RFID tag 11, and the specific content of the cleaning target confirmation process is different from the reference example, but is otherwise similar to the reference example. Since the basic flow of the cleaning target confirmation process is the same as that in FIG. 6, the process will be described with reference to FIG. Further, the data structure of the RFID tag 11 is different from that in FIG. 4 in that cleaning threshold data uniquely set by the manufacturer is used, but the other data structure is the same as that in FIG. Other than these, the configuration is the same as that of FIGS. 1, 2, 3, 5, and 7.

  In the present embodiment, prior to the reuse of the information display member 10, the selection reference information used as the selection reference in the manufacturer in which the information display member 10 is reused is written into the RFID tag 11 of the information display member 10. I am doing so. In the present embodiment, the information processing apparatus 33 and the RFID reader / writer 35 correspond to an example of “selection reference information writing unit”.

  Specifically, when the information processing measure 33 issues the information display member 10, it performs a process of confirming whether or not it is the first issue. In addition, confirmation of whether or not it is the first issue may be performed by confirming the total use count data, or by confirming whether or not the cleaning threshold data is already stored. . In the case of the first issuance, a process of storing the cleaning threshold data uniquely set by the manufacturer that uses the process management system 1 (that is, the manufacturer in which the information processing apparatus 33 is installed) is performed. . The cleaning threshold data may be stored in advance in the information processing apparatus 33, or may be input by an operator or the like at the time of the first issue. Here, the cleaning threshold uniquely set by the manufacturer using the process management system 1 corresponds to an example of “selection reference information”.

The following cleaning target confirmation process is performed on the premise that the information display member 10 is configured as described above and the cleaning threshold value (selection reference information) is written.
First, as in S101 of FIG. 6, the number of uses after cleaning is read. The processing in S101 is as described in the reference example . Thereafter, a threshold value reading process is performed (S102). This threshold value reading process is slightly different from the reference example, and the above-described threshold value written prior to the currently used reuse process (that is, the manufacturer using the process management system 1 uniquely sets the RFID 11 The cleaning threshold value stored in (1) is read. Then, the cleaning threshold read in S102 (those unique to the manufacturer) is compared with the number of uses after cleaning read in S101 (S103). If the threshold value is not reached, it is set as a cleaning target (S104), and if not, it is set as a non-cleaning target (S105). S104 and S105 are the same as those in the reference example .

  Also in the present embodiment, the information processing apparatus 21 corresponds to an example of “sorting unit” and “cleaning target sorting unit”, and the cleaning threshold value (sorting reference information) for the manufacturer in which the information display member 10 is reused is set as the RFID. In addition to checking with the tag 11, it functions to perform a sorting process based on the checked cleaning threshold and the above-mentioned post-cleaning use count (use history information).

  According to the configuration of the present embodiment, prior to the reuse of the information display member 10, the cleaning threshold value (selection reference information) used by the manufacturer in which the information display member 10 is reused is written. In the case of reuse, the cleaning countermeasure sorting process is performed based on the cleaning threshold (selection standard information) of the manufacturer in which the reuse is performed and the number of uses after cleaning (use history information). ing. In this way, the manufacturer that intends to reuse the product can use its own cleaning criteria when selecting the objects to be cleaned. Sorting can be performed based on the above.

In the above description, an example in which the cleaning target confirmation process is different from the reference example is shown, but the discard target confirmation process may be changed as follows.
In this example, the data structure of the RFID tag 11, and the specific content of the discarded confirmation process is different from the reference example, but is otherwise similar to the reference example. Since the basic flow of the discard target confirmation process is the same as that in FIG. 7, the process will be described with reference to FIG. Further, the data structure of the RFID tag 11 is different from that in FIG. 4 in that the threshold value data for disposal uniquely set by the manufacturer can be stored, but the other data structure is the same as that in FIG. Other than these, the configuration is the same as that of FIGS. 1, 2, 3, 5, and 7. In this example as well, the information processing apparatus 33 and the RFID reader / writer 35 correspond to an example of “selection reference information writing unit”.

  Also in this example, when the information processing measure 33 issues the information display member 10, it performs a process of confirming whether or not it is the first issue. In addition, confirmation of whether or not it is the first issue may be performed by confirming the total use count data, or by confirming whether or not the cleaning threshold data is already stored. . In the case of the first issuance, a process for storing the threshold value data for disposal that is uniquely set by the manufacturer that uses the process management system 1 (that is, the manufacturer in which the information processing apparatus 33 is installed) is performed. . The discard threshold data may be stored in advance in the information processing apparatus 33, or may be input by an operator or the like at the time of the first issue. In this example, the discard threshold uniquely set by the manufacturer using the process management system 1 corresponds to an example of “selection criterion information”.

In this example, the discard target sorting process is basically performed according to the flow shown in FIG. First, a process of confirming unique information and usage history information about the information display member 10 to be reused is performed (S110). This S110 is similar to the reference example . Thereafter, a determination process (S111) similar to that of the reference example is performed.

When the process proceeds to Yes in S111, a process for determining whether or not the total use count of the information display member 10 has reached the threshold value is performed (S112). The specific contents of this process are slightly different from the reference example, and the above-mentioned disposal threshold value (threshold value set by the manufacturer to be used for comparison of the total number of times of use) and the data of the total number of times of use are RFID tags. 11, and based on these data, it is determined whether or not the total number of uses of the information display member 10 has reached the discard threshold. If the total number of uses has not reached the discard threshold, the process proceeds to No in S112, and the information display member 10 is set as a non-discard target (S113). If the process proceeds to No in S111 (if the unique information or usage history information is not confirmed) or if the process proceeds to Yes in S112 (when the total number of uses reaches the discard threshold), the information display member 10 is discarded. The target is set (S114). Note that the processes in S113 and S114 are the same as those in the reference example .

  In this example, the manufacturer that wants to reuse can use its own standard when selecting the disposal target, and the manufacturer uses the company's own disposal standard while considering the usage history. Can be selected.

[Other Embodiments]
The present invention is not limited to the embodiments described with reference to the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention.

  In the above embodiment, the number of uses (issue number) of the information display member 10 is used as the use history information that serves as a selection index. However, the number of times the information display member 10 is washed may be used as the use history information. For example, in the process of FIG. 7, sorting is performed as a disposal target when the total number of uses reaches a threshold, but sorting may be performed as a disposal target when the number of cleanings reaches a certain threshold. Good. As described above, even when the number of cleanings is used as an index for selection at the time of reuse, it is possible to perform selection in consideration of contamination and deterioration.

In the reference example , when the usage history information is unreadable, the discarding process is performed as it is. However, the use prohibiting process may be performed at a stage before the discarding process as in the fourth embodiment. In such a case, an alarm may be issued.

  In the above embodiment, “total number of times used”, “number of times used after cleaning”, “number of times of cleaning”, and the like are used as the usage history information, but the present invention is not limited to these examples. For example, when some trouble occurs in the information display member 10, the number of occurrences and the contents of the trouble are stored in the RFID tag 11 as trouble data, and the trouble data is handled as usage history information. Also good. In this case, for example, it may be determined whether or not the number of failures has reached a threshold in S112 of the discard target selection process in FIG.

  In the above embodiment, as the “predetermined sorting process”, the sorting process for determining whether or not the information display member 10 is a cleaning target and the sorting process for determining whether or not to discard the information display member 10 are exemplified. I can't. For example, a selection process for determining whether or not some kind of inspection is performed on the information display member, a selection process for determining whether or not any information is recorded on the information display member, and the like may be performed.
