  However, individual management of such a textile product that has been repeatedly cleaned has not been realized. For example, it is common to determine whether to discard or continue to use rental items, etc. based on the experience and intuition of workers and appearance, with little consideration of information such as the number of years of use and the number of washings related to textile products.

It is preferable that the degree of consumption is calculated by multiplying the results and adding up the multiplied values for each consumption process content.

  In the system 100, the tag data acquisition unit 110 executes the reading process on the tag information obtained by the reading process on the RFID tag 10 attached to the textile product 20 when the textile product 20 is discarded. When it is assumed that the information is acquired from the tag reader 150, the processing result storage unit 112 identifies the corresponding fiber product 20 in the product information database 126 based on the tag information obtained in the disposal process, and the fiber product 20 It is preferable to store the disposal results.

  The user information database 125 is a database that stores information on a user who uses the textile product 20. Such a user information database 125 uses, for example, the business name 5061 (user name) as a key, the business address 5062, the contact 5063, the name of the person in charge 5064, the user coefficient 5065, and the textile product 20 in use. It is an aggregate of records in which information such as tag ID 5066 is associated. In addition, it can be assumed that the user coefficient 5065 is a coefficient set in accordance with, for example, the usage pattern or usage frequency of the textile product 20 by the user. In this case, the user coefficient 5065 is also increased in accordance with the magnitude of the influence of the usage pattern, usage frequency, etc. on the consumption of the textile product 20.

  In addition, the product information database 126 is a database that stores, for each RFID tag 10 attached to the textile product 20, processing result data of the consumption process in association with the tag information. Such a product information database 126 has, for example, the tag ID 5071 of the RFID tag 10 as a key, the product name 5072 of the textile product 20, the delivery date 5073 (the date on which the lending started), the number of washings 5074, the number of stains 5075, the number of presses. 5076, wear level limit value 5077, wear level limit actual value 5078, wear level 5079, disposal result 5080, and product coefficient 5085 are associated with a set of records.

  The cleaning information database 127 is a database that stores information on a cleaning process that is a consumption process of the textile product 20.

It is a collection of records.

--- Main flow example ---
Hereinafter, the actual procedure of the textile product life cycle management method in the present embodiment will be described with reference to the drawings. Various operations corresponding to the textile product life cycle management method described below are realized by a program 102 that the system 100 reads into the memory 103 and executes. And this program 102 is comprised from the code | cord | chord for performing the various operation | movement demonstrated below.

  First, the concept of the textile product life cycle management method will be outlined. FIG. 3 is a diagram showing an overall outline of the present embodiment. In the present embodiment, as shown in FIG. 3, a tag reader 150 is applied to a textile product 20 such as a linen product or a clothing item to which the RFID tag 10 is attached in advance when the textile product 20 enters the cleaning factory 500. The reading process by is executed. The tag reader 150 transmits storage information of the RFID tag 10 to the system 100 via a network 140 such as a LAN.

  While the system 100 receives and acquires this, the user information database 125, the product information database 126, and the cleaning information database 127 are searched in the storage device included in the system 100 to extract the corresponding information. Further, the system 100 calculates the degree of wear of the individual (textile product 20) using the extracted information, and transmits the result of calculation of the degree of wear to the client terminal 200. If the degree of wear is equal to or greater than a certain level, information on the individual (textile product 20) whose wear level has exceeded a certain value (wear level limit) is output to the client terminal 200 as a product to be discarded.

  The user can confirm the information on the textile product 20 displayed on the client terminal 200 to recognize the presence of the product to be discarded and reliably dispose of it. In this case, the user inputs information (such as a wear limit limit actual value) of the fiber product 20 actually discarded at the client terminal 200 and transmits it to the system 100. The system 100 receives this and registers the disposal of the textile product 20 in the product information database 126. On the other hand, when the wear level of the textile product 20 does not exceed a certain value (a wear level limit value), the system 100 does not output special information to the client terminal 200 (of course, notifying that there is no problem with the wear level). Also good). The user who recognizes this situation sends the textile product 20 to the cleaning process.

  Next, an actual processing flow in the system 100 will be described. FIG. 4 is a flowchart of the warehousing process of the present embodiment. When the textile product 20 enters the cleaning factory 500, the system 100 acquires tag information obtained by the reading process for the RFID tag 10 attached to the textile product 20 from the tag reader 150 that has executed the reading process (S1000). . Then, the product information database 126 is searched for the corresponding fiber product 20 based on the acquired tag information (S1001).

  For the fiber product 20 specified by the search, information related to the fiber product 20 is extracted from the user information database 125, the product information database 126, and the cleaning information database 127, and the wear level of the fiber product 20 is calculated according to a predetermined calculation. This is executed based on Expression 700 (see FIG. 7B) (S1002). The concept of the wear level and a detailed example of the calculation will be described later. As an outline, for example, the number of days elapsed from the start of use of the fiber product 20 is multiplied by a coefficient (the reciprocal of the wear level limit value for each fiber product 20). The coefficient determined for each process (each process content) in the integrated value (process results) of the previous processing times of the stain removal process, washing process, and press drying process, which is the consumption process, Is multiplied to obtain a multiplication value. Then, the wear level is calculated by multiplying the sum of the two multiplied values by the user coefficient. This consumption level may be output from the system 100 to the client terminal 200. In this output, the wear level obtained by searching the product information database 126 based on the tag information (in this case, the one at the time of the previous warehousing) may be output.

When the degree of wear calculated in step S1002 exceeds 100% (S1003: YES), the system 100 uses the information on the corresponding textile product 20 and the corresponding tag information as the notification contents to be discarded as a client terminal. 200 (S1004). When the user who recognizes this notification executes the disposal of the corresponding textile product 20, the processing result of the disposal (for example, the number of days that the disposal process has been completed) is sent from the user to the client terminal 200 via the input interface. Is input. The client terminal 200 acquires this and sends it to the system 100. The system 100 stores the disposal processing results in the product information database 126.
On the other hand, if the degree of wear does not exceed 100% (S1003: NO), the system 100 notifies the client terminal 200 that the process proceeds to the cleaning process (S1005).

  In step S1004, the client terminal 200 that has received the notification of proceeding to the cleaning process displays that fact on the output interface and notifies the user. The user recognizes this, and carries the textile product 20 into the cleaning process. Here, wear processing such as stain removal, washing, and press drying, which is mainly performed in the cleaning factory 500, is performed on the fiber product 20. Next, the flow of processing in the cleaning process will be described. FIG. 5 is a flowchart of the cleaning process of the present embodiment.

  Here, the system 100 acquires the reading result, that is, tag information, of the RFID tag 10 attached to the textile product 20 from the tag reader 150 of the client terminal 200, for example, in each of the stain removal, washing, and press drying steps (S1100). At this time, it is assumed that the tag reader 150 transmits tag information to the system 100 via a network 140 such as a LAN.

  The system 100 searches for the corresponding fiber product 20 based on the tag information in the product information database 126 or the like (S1101), and acquires the processing contents of the process and the data of the processing results from the client terminal 200 (S1102). Note that, depending on the textile product 20, there may be only a washing process, or only a washing process and a press drying process, so that the processing contents and the processing results associated therewith are not limited to a fixed case.

  Examples of the processing contents and processing results include, for example, the dirt level and size of the textile 20, the distinction between dry cleaning and water cleaning in the cleaning process, the washing capacity of the machine used in the cleaning process, and dry cleaning. Chemical solution used, set temperature for each process (eg: hot water used during washing, chemical heating temperature when removing stains, press temperature, etc.), strength (eg: pressure and blow on textile products 20 during stain removal, washing, press drying, etc.) Strength, pulling strength in the press drying process, etc.), time (e.g., chemical solution leaching time at the time of stain removal, washing time, time required for pressing and drying) and the like.

  In this way, the system 100 that has acquired the processing content and the processing result data from the client terminal 200 accumulates the processing content data in the cleaning information database 127 and the processing result data in the product information database 126 for each textile product 20 ( S1103). Note that the processing result data includes a device that performs a consumption process such as a cleaning device 300 (a device that performs the above-described processes, including the press device 400), a monitoring device 310 of the device, and a user in the cleaning factory 500. The client terminal 200 acquires the data input from any of the input interfaces that can directly accept the data input and transmits it to the system 100.

  The processing results obtained in this way are accumulated in the product information database 126, and used in the processing flow described above with reference to FIG. Therefore, every time the textile product 20 is received, in the steps S1000 to S1003 executed by the system 100, the processing results up to the previous receipt of the textile product 20 are used for the processing.

  Next, the process flow accompanying a delivery process is demonstrated. FIG. 6 is a flowchart of the delivery process of the present embodiment. In this case, the system 100 acquires the RFID tag 10 reading processing result, that is, tag information, from the tag reader 150 associated with the delivery process for the textile product 20 that is delivered, that is, delivered again to the user. (S1200). Further, the system 100 executes an information search related to the textile product 20 based on the tag information in the product information database 126 (S1201).

Here, the system 100 performs a matching check of the fiber product 20 that has become a delivery item (S1202). This matching check, for example, collates the number of textile products 20 scheduled to be delivered in the product information database 126 with the number of textile products 20 present in the delivery process acquired from the tag reader 150. Alternatively, it is possible to check each tag product in each fiber product 20 for consistency or inconsistency. When a mismatch occurs in the matching check (S1202: NO), the system 100 displays a shipping error on the client terminal 200 and ends the process. In this error display, for example, the individual information of the fiber product 20 that is insufficient from the shipping schedule is extracted from the product information database 126 and included.
On the other hand, if there is no mismatch in the matching check (S1202: YES), the system 100 outputs delivery instruction information to the client terminal 200 (S1204), and ends the process.

--- About the concept of wear level calculation ---
Next, a method for calculating the wear level will be described. In realizing the fiber product life cycle management method of the present invention, the system 100 calculates a predetermined calculation formula for the processing results based on the processing results data stored in the product information database 126, and accumulates the processing results. The degree of wear that correlates with the degree is calculated for each textile product. In addition, the system 100 calculates the reciprocal of the wear limit value determined for each content of the wear processing, and acquires a coefficient for each content of the wear processing. This coefficient is as described above along the product information database 126 in FIG. The system 100 multiplies this coefficient by the processing result, and adds up the multiplied value for each consumption process content to calculate the degree of consumption.

  Further, when there is a textile product 20 that has been discarded as described above, the system 100 extracts the processing results of this individual textile product from the product information database 126, and the processing results up to this disposal processing (e.g., disposal) The total number of days until the process) is multiplied by the coefficient as the exhaustion limit actual value. In addition, the system 100 determines whether or not the result of adding the multiplication values for each consumption process content exceeds 1. When the sum exceeds 1 in this determination, the system 100 calculates a division value obtained by dividing the coefficient of the predetermined consumption process content by the coefficient of the predetermined consumption process content and the sum of the coefficients of the other consumption process contents. Multiply. Then, the multiplication value is updated and registered in the product information database 126 as a coefficient of the predetermined consumption processing content. That is, the coefficient stored in the product information database 126 is continuously updated to a more appropriate value according to the actual life of the textile product 20. Thus, by continuing the feedback process of the coefficient, the accuracy of the textile product life cycle management is continuously increased, and the efficiency of the life cycle management is also improved.

  For example, as shown in FIG. 7, such a degree of wear can be regarded as a cause of decreasing the asset value as the textile product 20 is used. This degree of wear is greatly affected by factors such as washing deterioration caused by washing the fiber product 20 and deterioration due to aging of the fiber product material itself. Therefore, as in the calculation formula 700 of the degree of wear shown in FIG. 7B, the factors of the deterioration of washing such as “stain removal number”, “dry washing number”, “water washing number”, “press drying number”, and “ The element of “elapsed product days” is added to the basis for calculating the degree of wear. In addition, this calculation formula 700 is obtained by multiplying the number of days elapsed from the start of use of the textile product 20 by the product coefficient (see FIG. 2B) and the previous time of each of the stain removal process, the washing process, and the press drying process. The process of adding the value obtained by multiplying the integrated value of the number of times (the number of blottings, the number of times of water washing, the number of times of press drying) by a coefficient determined for each process, and further multiplying by the user coefficient is shown.

  As an example of the process for calculating the degree of wear captured as described above, a calculation method for obtaining the degree of wear for a uniform such as a suit will be considered. At this time, the product coefficient is “0.12”, and the number of days elapsed since product purchase is 90 days. Also, the stain removal is performed once, the strength is normal, and the stain removal coefficient is “0.1”. In addition, the washing is a 100 kg type washing machine, and dry cleaning using a petroleum solvent is performed seven times, and the cleaning coefficient is set to “0.12.” In press drying, the overall press and the neck press are set at a temperature of 50 ° C. for 3 minutes, the strength is usually 7 times, and the press coefficient is “0.09”.

  According to the calculation formula 700, the wear level in this case is (90 × 0.12) + (1 × 0.1) + (7 × 0.12) + (7 × 0.09) = 12.37. It becomes. In this case, the consumption level increase per month is 12.37 / 3 = 4.123. Therefore, when the same process is repeated under the same conditions, (100-12.37) /4.123=21 (months), and the suit is calculated to be discarded after about 1 year and 9 months.

  These various coefficients may be set by the administrator of the textile product life cycle management system 100 in consideration of empirical rules.

--- About the concept of the coefficient ---
Next, the coefficient will be described. FIG. 8 is a graph showing the relationship between the number of washes and the degree of wear and (b) the relationship between the number of washes and the degree of wear with respect to temperature in this embodiment.

  First, regarding the washing coefficient, the initial value of the washing coefficient is calculated based on the wear level limit value based on, for example, demonstration experiment data. As shown in the figure, for example, a continuous washing experiment under standard washing conditions is performed, and the slope (reciprocal) of the number of times of washing that has reached the wear limit is taken as the washing coefficient. In the example of the figure, 1/200 = 0.005 is the washing coefficient.

  On the other hand, experimental data can also be used for correction of washing conditions. In this case, a continuous washing experiment is performed under different washing conditions (washing water temperature), and a correction value is calculated based on the number of washings that has reached the wear limit. In the example shown in the figure, when the temperature is 50 ° C., the wear level limit value is 160 times, and when the temperature is 90 ° C., the wear level limit value is 120 times. At this time, the respective correction values are 200/160 = 1.25 and 200/120 = 1.67. This correction value is multiplied by the washing coefficient in the calculation formula 700, for example.

  It can also be assumed that the coefficient is corrected according to the chemical used for washing. FIG. 9 is a graph showing a relationship between the number of times of washing and the degree of consumption with respect to the chemical concentration, and (b) a graph showing the relation between the number of times of washing and the degree of consumption with respect to the chemical type in this embodiment. In this case, for example, a continuous washing experiment is performed while changing the washing conditions (chemical solution concentration), and the correction value is calculated based on the number of washings that has reached the wear limit. In the example shown in the figure, the depletion limit value is 150 times for the chemical solution diluted 15 times, and the depletion degree limit value is 70 times for the chemical solution diluted 10 times. Therefore, the correction values in each case are 200/150 = 1.33 and 200/70 = 2.86. This correction value is multiplied by the washing coefficient in the calculation formula 700, for example.

  In addition, it is possible to calculate a correction value based on the number of times of washing that has reached the wear limit, by performing a continuous washing experiment while changing the washing condition (chemical solution type). In the case of FIG. 5B, the exhaustion limit value is 230 times for the chemical type B and the exhaustion limit value is 180 times for the chemical type C. Therefore, the respective correction values are 200/230 = 0.87 and 200/180 = 1.11. This correction value is multiplied by the washing coefficient in the calculation formula 700, for example.

  Further, the coefficient due to aging of the fiber product 20 is considered as follows. FIG. 10 is a graph showing the standard number of days of use in the relationship between the number of washings and the degree of wear in this embodiment. Here, the aged deterioration of the textile product 20 is calculated by the standard number of days used. In this case, the initial setting of the contribution rate of product deterioration is assumed to be the number of washings: aged deterioration = 6: 4, and the standard use days are multiplied by 1.5. At this time, the coefficient of aging deterioration is the reciprocal of the standard service life obtained by multiplying the standard service life of the product by 1.5. In the example in the figure, 1/1095 = 0.0009 is a coefficient of aging degradation. For example, when a standard uniform is washed once a week at 35 ° C. using the chemical solution A, the equation 0.005 × X × 1/7 + 0.0009 × X = 1 holds. At this time, X becomes X = 619.5. In other words, the wear level of the uniform is 100% when it exceeds about 620 days.

  Next, a concept of performing a coefficient feedback process according to the disposal result of the textile product 20 will be described. FIG. 11 is a graph showing the distribution of the actual number of days until disposal in the relationship between the number of days elapsed and the number of washings in this embodiment. In the case of this graph, the elapsed days from the start of use to the disposal of the textile product 20 are plotted in association with the number of washings. For this plot data, the contribution rate of product deterioration is obtained by the least square method, and the result is fed back to the existing coefficient of the product information database 126.

  In the example of the figure, for example, the degree of wear due to washing is 100 (number of washings) × 0.005 (washing coefficient) = 0.5, and the degree of wear due to aging is 700 (elapsed days) × 0.00009 ( (Aging coefficient) = 0.63. In other words, when both are added, it exceeds “1”. Therefore, since the number of washings is calculated based on experiments, it is fixed and the coefficient of aging deterioration is adjusted. In the above example, the sum of both wear levels exceeds 1.0, so that the coefficient of aging deterioration is divided by a value of 0.5 / 0.63. In that case, 0.00009 × 0.5 / 0.63 = 0.000714 can be calculated as a new coefficient of deterioration over time. The coefficient of aging deterioration becomes update information for the corresponding record in the product information database 126. In this way, by continuing the textile product life cycle management method of the present invention, it becomes possible to constantly optimize the coefficient.

According to the present invention, it is possible to grasp cost amortization based on the number of washings and elapsed days, to set a cleaning price by grasping the washing frequency of textile products, to manage risk of product loss by the customer, and to enhance wear level management by setting the usage status of the customer Is possible.
Therefore, efficient and accurate life cycle management of the textile product can be established.
