Description

[Technical Field]

[0001] The present disclosure relates to a tire manufacturing management device, a tire manufacturing management system, a tire manufacturing management method, and a program. [Background technology]

[0002] Retread tires are known, which are manufactured by scraping the tread surface of a tire that has reached the end of its primary life to a predetermined size to produce a base tire, and then re-adhering and forming a new tread onto the base tire. Additionally, techniques related to predicting the state of tire deterioration are also known. For example, Patent Document 1 discloses a method for predicting the state of tire deterioration that can improve the accuracy of predicting the state of deterioration of tires that are in use or have been used. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-219477 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional technology described in Patent Document 1, sufficient consideration has not been given to optimizing the production of retread tires in accordance with the predicted state of tire deterioration.

[0005] The present disclosure provides techniques that can optimize the production of retread tires. [Means for solving the problem]

[0006] A tire manufacturing management device according to an embodiment of the present disclosure includes: (1) A tire manufacturing management device for managing the manufacturing of retread tires, A control unit is provided, the control unit acquiring identification information of a base tire used in manufacturing the retread tire; acquiring a remaining durability index of the base tire based on the acquired identification information; determining a vulcanization temperature condition in a vulcanization step based on the acquired remaining durability index; The determined vulcanization temperature conditions are output. This allows the tire manufacturing management device to optimize the manufacturing of retread tires.

[0007] (2) The tire manufacturing management device according to (1) above, The control unit may determine at least a temperature condition inside the base tire in a mold as the vulcanization temperature condition. This allows the tire manufacturing management device to contribute to controlling the heating of the base tire from the inside by the vulcanizer, thereby shortening the time required for the vulcanization process by the vulcanizer.

[0008] (3) The tire manufacturing management device according to (1) or (2) above, When the control unit determines that the remaining durability index when the vulcanization process is performed under normal conditions is within a first reference range or within a second reference range larger than the first reference range, the control unit may determine the normal conditions as the vulcanization temperature conditions. This allows the tire manufacturing management device to contribute to the manufacturing of retread tires that can be used up just once or that can be retreaded only once during the period from the start of use to the end of their lifespan.

[0009] (4) The tire manufacturing management device according to (3) above, When the control unit determines that the remaining durability index is within a first range that is greater than the first reference range and smaller than the second reference range, it may determine a first temperature condition that is higher than the normal condition as the vulcanization temperature condition. As a result, when the value of the remaining durability index is within the standard range, the tire manufacturing management device can use the difference from the standard range to consume more durability by heating at a higher temperature in the vulcanization process, thereby contributing to shortening the vulcanization time.

[0010] (5) The tire manufacturing management device according to (4) above, When the control unit determines that the remaining durability index is within a second range that is greater than the first range and smaller than the second reference range, it may determine a second temperature condition that is lower than the normal condition as the vulcanization temperature condition. This allows the tire manufacturing management device to compensate for the difference from the standard range when the value of the remaining durability index is not within the standard range by using less durability through heating at a lower temperature in the vulcanization process, thereby contributing to improving the durability of the retreaded tire.

[0011] (6) The tire manufacturing management device according to any one of (3) to (5) above, When the control unit determines that the remaining durability index is within a third range that is smaller than the first reference range, the control unit may determine a third temperature condition that is lower than the normal condition as the vulcanization temperature condition. This allows the tire manufacturing management device to compensate for the difference from the standard range when the value of the remaining durability index is not within the standard range by using less durability through heating at a lower temperature in the vulcanization process, thereby contributing to improving the durability of the retreaded tire.

[0012] (7) The tire manufacturing management device according to any one of (1) to (6) above, The control unit may acquire usage conditions when a user uses the manufactured retread tire, and determine the vulcanization temperature conditions based on the usage conditions in addition to the remaining durability index. This allows the tire manufacturing management device to contribute to the manufacturing of retread tires with an appropriate remaining durability index tailored to the user.

[Figure 3] 2 is a flowchart illustrating an example of a tire manufacturing management method executed by the tire manufacturing management device of FIG. [Figure 4] 2 is a table for explaining an example of the operation of the tire manufacturing management device of FIG. 1. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0018] An embodiment of the present disclosure will be mainly described below with reference to the accompanying drawings. The following description also applies to a tire manufacturing management system including a tire manufacturing management device 10, and a tire manufacturing management method and program executed by the tire manufacturing management device 10, to which the present disclosure is applied.

[0019] Fig. 1 is a block diagram showing an example of the configuration of a tire manufacturing management system 1 including a tire manufacturing management device 10 according to an embodiment of the present disclosure. An example of the configuration and functions of the tire manufacturing management system 1 including the tire manufacturing management device 10 according to an embodiment of the present disclosure will be mainly described with reference to Fig. 1. The tire manufacturing management system 1 includes a vulcanizing device 20 in addition to the tire manufacturing management device 10.

[0020] 1 illustrates only one tire manufacturing management device 10 and one vulcanizing device 20 for ease of explanation, but the tire manufacturing management system 1 may include two or more of each device. For example, each of the tire manufacturing management device 10 and the vulcanizing device 20 is communicatively connected to a network 30 including a mobile communication network and the Internet. As an example, the tire manufacturing management device 10 is communicatively connected to the vulcanizing device 20 via the network 30.

[0021] The tire manufacturing management apparatus 10 may include one or more server devices capable of communicating with each other, or may include any general-purpose electronic device, including a personal computer (PC), a tablet PC, a smartphone, or a wearable device such as a smart watch. Without being limited to these, the tire manufacturing management apparatus 10 may also include other electronic devices dedicated to the tire manufacturing management system 1. The tire manufacturing management apparatus 10 manages the manufacturing of retread tires. For example, the tire manufacturing management apparatus 10 cooperates with a vulcanizing apparatus 20 to manage the vulcanizing process, which is part of the manufacturing process of retread tires.

[0022] As an overview of one embodiment, a tire manufacturing management device 10 acquires identification information of a casing tire used in manufacturing a retread tire. In the present disclosure, "identification information" includes information for identifying the tire as an individual, which can be read from, for example, an RFID (Radio Frequency Identification) tag and a QR (Quick Response) code (registered trademark) provided on the tire.

[0023] The tire manufacturing management device 10 acquires a remaining durability index of the casing tire based on the acquired identification information. In the present disclosure, the "remaining durability index" includes, for example, an index based on the durability index value consumed from the start of use of a new or retreaded tire until the tire's tread wears out and the tire reaches the end of its life. For example, the durability index value may be 1.0.

[0024] For example, a remaining durability index of 1.0 means that a new or retreaded tire can be used only once from the time it is first used until the end of its life. For example, a remaining durability index of 2.0 means that a new or retreaded tire can be retreaded only once more from the time it is first used until the end of its life. In other words, it can be used twice.

[0025] The remaining durability index is an index corresponding to the deterioration state of a tire. A possible method for estimating the remaining durability index of a casing tire is a method based on the rubber physical properties, usage period, mileage, degree of wear, customer profile, etc. of the recovered casing tire. Any conventional method for estimating the remaining durability index may be adopted as such a method.

[0026] The tire manufacturing management apparatus 10 determines the vulcanization temperature conditions in the vulcanization process based on the acquired remaining durability index. In the present disclosure, the "vulcanization temperature conditions" include, for example, at least the temperature conditions inside the base tire in the mold. The vulcanization temperature conditions may include only the temperature conditions inside the base tire, or may include temperature conditions both inside and outside the base tire.

[0027] The tire manufacturing management apparatus 10 outputs the determined vulcanization temperature conditions to the vulcanizer 20. In the present disclosure, "outputting the vulcanization temperature conditions to the vulcanizer 20" may include, for example, outputting the vulcanization temperature conditions determined by the tire manufacturing management apparatus 10 as information from the vulcanizer 20 to notify a user, or may include directly mechanically controlling the vulcanizer 20 to perform the vulcanization process under the vulcanization temperature conditions.

[0028] The vulcanizing device 20 includes any device that performs a vulcanization process when manufacturing retread tires. The vulcanizing device 20 includes, for example, a remolding type device that can set conditions for each tire during vulcanization. The vulcanizing device 20 uses the remolding type to separately control the temperatures inside and outside the tire within the mold. The vulcanizing device 20 is not limited to the remolding type and may include a precure type device.

[0029] 1, an example of the configuration of each of a tire manufacturing management device 10 and a vulcanizing device 20 included in the tire manufacturing management system 1 will be mainly described.

In one embodiment, the tire manufacturing management apparatus 10 is communicatively connected to the network 30 via the communication unit 11. The communication unit 11 transmits and receives various information via the network 30.

[0032] The storage unit 12 includes storage modules such as an HDD (Hard Disk Drive), an SSD (Solid State Drive), an EEPROM (Electrically Erasable Programmable Read-Only Memory), a ROM (Read-Only Memory), and a RAM (Random Access Memory). The storage unit 12 stores information necessary to realize the operation of the tire manufacturing management apparatus 10. The storage unit 12 stores information obtained by the operation of the tire manufacturing management apparatus 10. For example, the storage unit 12 stores system programs, application programs, and various data acquired by any means such as communication.

[0033] The memory unit 12 may function as a main memory module, an auxiliary memory module, or a cache memory. The memory unit 12 is not limited to being built into the tire manufacturing management device 10, and may include an external memory module connected via a digital input / output port such as a USB.

[0034] The control unit 13 includes one or more processors. In the present disclosure, a "processor" refers to, but is not limited to, a general-purpose processor or a dedicated processor specialized for a specific process. The control unit 13 includes, for example, a CPU (Central Processing Unit). The control unit 13 is communicably connected to each component of the tire manufacturing management apparatus 10 and controls the operation of the entire tire manufacturing management apparatus 10.

[0035] The vulcanizing device 20 included in the tire manufacturing management system 1 has a communication unit 21, a storage unit 22, a vulcanizing unit 23, an input unit 24, an output unit 25, and a control unit 26.

[0036] The communication unit 21 includes one or more communication interfaces. The communication interfaces are communicatively connected to, for example, a network 30. The communication interfaces are compatible with mobile communication standards such as 4G and 5G, wired LAN standards, or wireless LAN standards, but are not limited to these and may be compatible with any communication standard. In one embodiment, the vulcanizing apparatus 20 is communicatively connected to the network 30 via the communication unit 21. The communication unit 21 transmits and receives various information via the network 30.

[0037] Additionally, the communication interface of the communication unit 21 may be compatible with any wireless communication standard or wired communication standard for wireless or wired communication.

[0042] The output unit 25 includes one or more output interfaces that output information to provide it to the user, such as a display that outputs information visually as an image, a speaker that outputs information audibly as sound, and a vibrator that outputs information tactilely as vibration.

[0043] The control unit 26 includes one or more processors. The control unit 26 includes, for example, a CPU. The control unit 26 is communicably connected to each component that makes up the vulcanizing device 20, and controls the operation of the vulcanizing device 20 as a whole.

[0044] Fig. 2 is a sequence diagram for explaining an example of a tire manufacturing management method executed by the tire manufacturing management system 1 of Fig. 1. The sequence diagram shown in Fig. 2 shows a basic processing flow of the tire manufacturing management method executed by the tire manufacturing management system 1. With reference to Fig. 2, an example of a tire manufacturing management method executed by the tire manufacturing management system 1 including the tire manufacturing management device 10 of Fig. 1 will be mainly explained.

[0045] In step S101, the control unit 13 of the tire manufacturing management apparatus 10 acquires identification information of a base tire used in manufacturing a retread tire. For example, the control unit 13 acquires the identification information read by a reader from an RFID tag, a QR code, or the like provided on the tire, from the reader by any method. The reader may be located in the vulcanizer 20 or in a location different from the vulcanizer 20.

[0046] In step S102, the control unit 13 of the tire manufacturing management apparatus 10 acquires the remaining durability index of the casing tire based on the identification information acquired in step S101.

[0047] In step S103, the control unit 13 of the tire manufacturing management apparatus 10 determines the vulcanization temperature conditions for the vulcanization process based on the remaining durability index acquired in step S102. For example, the control unit 13 determines the temperature conditions of at least the inside of the base tire in the mold as the vulcanization temperature conditions.

[0048] In step S104, the control unit 13 of the tire manufacturing management apparatus 10 outputs the vulcanizing temperature conditions determined in step S103 to the vulcanizing apparatus 20. For example, the control unit 13 transmits the vulcanizing temperature conditions determined in step S103 to the vulcanizing apparatus 20 via the communication unit 11 and the network 30. The control unit 26 of the vulcanizing apparatus 20 receives the vulcanizing temperature conditions determined in step S103 from the tire manufacturing management apparatus 10 via the network 30 and the communication unit 21. As a result, the control unit 26 acquires the vulcanizing temperature conditions determined in step S103 from the tire manufacturing management apparatus 10.

[0049] In step S105, the control unit 26 of the vulcanizing device 20 carries out the vulcanization process based on the vulcanization temperature conditions acquired from the tire manufacturing management apparatus 10 in step S104. For example, the control unit 26 may output the vulcanization temperature conditions determined by the tire manufacturing management apparatus 10 as information from the output unit 25 to notify a user. The control unit 26 may acquire the vulcanization temperature conditions that the user, who received the notification from the output unit 25, finally input as input information using the input unit 24, and control the vulcanizing unit 23 under the vulcanization temperature conditions to carry out the vulcanization process. For example, the control unit 26 may mechanically control the vulcanizing unit 23 to directly carry out the vulcanization process under the vulcanization temperature conditions determined by the tire manufacturing management apparatus 10.

[0050] The vulcanizing unit 23 of the vulcanizing device 20 may heat at least the inside of the base tire in the mold in accordance with the vulcanization temperature conditions. For example, the vulcanizing unit 23 may heat only the inside of the base tire, or may heat both the inside and outside of the base tire.

[0051] Fig. 3 is a flowchart for explaining an example of a tire manufacturing management method executed by the tire manufacturing management apparatus 10 of Fig. 1. The flowchart shown in Fig. 3 shows a more detailed flow of the determination process of step S103 of Fig. 2 executed by the tire manufacturing management apparatus 10. With reference to Fig. 3, an example of a tire manufacturing management method executed by the tire manufacturing management apparatus 10 of Fig. 1 will be explained in more detail.

[0052] In step S201, the control unit 13 of the tire manufacturing management apparatus 10 determines whether the remaining durability index obtained when the vulcanization process is performed under normal conditions, i.e., the remaining durability index obtained in step S102 of FIG. 2, is within a reference range. In the present disclosure, the "reference range" includes, for example, a range of the remaining durability index when a retreaded tire can be used up in one use from the start of use to the end of its life, or when the tire can be retreaded at least once during its life. The reference range includes, for example, a first reference range and a second reference range that is larger than the first reference range. As an example, the first reference range of the remaining durability index is a range of 1.0 or more and less than 1.2. As an example, the second reference range of the remaining durability index is a range of 2.0 or more.

[0053] The control unit 13 of the tire manufacturing management apparatus 10 determines whether the remaining durability index is within a first reference range or a second reference range, for example, in step S201. If the control unit 13 determines that the remaining durability index is within the first reference range or within a second reference range that is larger than the first reference range, it executes the process of step S202. If the control unit 13 determines that the remaining durability index is not within the reference range, it executes the process of step S203.

[0054] In step S202, if the control unit 13 of the tire manufacturing management apparatus 10 determines in step S201 that the remaining durability index is within the first reference range or within a second reference range that is larger than the first reference range, the control unit 13 determines the normal condition as the vulcanization temperature condition. For example, the control unit 13 determines the vulcanization temperature of the vulcanization process performed by the vulcanizing unit 23 of the vulcanizer 20 to be the standard temperature.

[0055] In step S203, if the control unit 13 of the tire manufacturing management apparatus 10 determines that the remaining durability index is not within the reference range in step S201, the control unit 13 determines whether the remaining durability index is within the first range. In the present disclosure, the "first range" includes, for example, a range of the remaining durability index when there is a margin for the value relative to the reference range. The first range is, for example, larger than the first reference range and smaller than the second reference range. As an example, the first range of the remaining durability index is a range of 1.2 or more and less than 1.8, adjacent to the first reference range. If the control unit 13 determines that the remaining durability index is within the first range, the control unit 13 executes the processing of step S204. If the control unit 13 determines that the remaining durability index is not within the first range, the control unit 13 executes the processing of step S205.

[0056] In step S204, if the control unit 13 of the tire manufacturing management apparatus 10 determines in step S203 that the remaining durability index is within a first range that is greater than the first reference range and smaller than the second reference range, the control unit 13 determines a first temperature condition that is higher than the normal condition as the vulcanization temperature condition. For example, the control unit 13 determines the vulcanization temperature of the vulcanization process performed by the vulcanization unit 23 of the vulcanizer 20 to be the first temperature that is higher than the standard temperature. The first temperature condition is a condition that can improve the efficiency of production of retread tires, although it results in a lower remaining durability index than when the vulcanization process is performed under normal conditions.

[0057] The control unit 13 of the tire manufacturing management apparatus 10 may subdivide the first range according to the value of the remaining durability index within the first range and determine multiple stages of first temperatures. For example, the control unit 13 may determine multiple first temperatures that are higher than the standard temperature but different from each other when the remaining durability index is equal to or greater than 1.2 and less than 1.5 and when the remaining durability index is equal to or greater than 1.5 and less than 1.8.

[0058] In step S205, if the control unit 13 of the tire manufacturing management apparatus 10 determines that the remaining durability index is not within the first range in step S203, the control unit 13 determines whether the remaining durability index is within the second range. In the present disclosure, the "second range" includes, for example, a range of the remaining durability index when there is no margin for the value relative to the reference range. The second range is, for example, larger than the first range and smaller than the second reference range. As an example, the second range of the remaining durability index is a range of 1.8 or more and less than 2.0, adjacent to the first range and the second reference range. If the control unit 13 determines that the remaining durability index is within the second range, the control unit 13 executes the process of step S206. If the control unit 13 determines that the remaining durability index is not within the second range, the control unit 13 executes the process of step S207.

[0059] In step S206, if the control unit 13 of the tire manufacturing management apparatus 10 determines in step S205 that the remaining durability index is within a second range that is greater than the first range and smaller than the second reference range, the control unit 13 determines a second temperature condition that is lower than the normal condition as the vulcanization temperature condition. For example, the control unit 13 determines the vulcanization temperature of the vulcanization process performed by the vulcanization unit 23 of the vulcanizer 20 to be the second temperature that is lower than the standard temperature. The second temperature condition is a condition that reduces productivity of retread tires, but obtains a remaining durability index that is higher than the remaining durability index obtained when the vulcanization process is performed under normal conditions.

[0060] The control unit 13 of the tire manufacturing management apparatus 10 may subdivide the second range according to the value of the remaining durability index within the second range and determine multiple stages of the second temperature. For example, the control unit 13 may determine multiple second temperatures that are lower than the standard temperature but different from each other when the remaining durability index is equal to or greater than 1.8 and less than 1.9 and when the remaining durability index is equal to or greater than 1.9 and less than 2.0.

[0061] In step S207, if the control unit 13 of the tire manufacturing management apparatus 10 determines that the remaining durability index is not within the second range in step S205, it determines whether the remaining durability index is within the third range. In the present disclosure, the "third range" includes, for example, a range of the remaining durability index when there is no margin for the value relative to the reference range. The third range is, for example, smaller than the first reference range. As an example, the third range of the remaining durability index is a range of 0.8 or more and less than 1.0, adjacent to the first reference range. If the control unit 13 determines that the remaining durability index is within the third range, it executes the processing of step S208. If the control unit 13 determines that the remaining durability index is not within the third range, it terminates the processing.

[0062] In step S208, if the control unit 13 of the tire manufacturing management apparatus 10 determines in step S207 that the remaining durability index is within a third range that is smaller than the first reference range, the control unit 13 determines a third temperature condition, which is a temperature lower than the normal condition, as the vulcanization temperature condition. For example, the control unit 13 determines the vulcanization temperature of the vulcanization process performed by the vulcanization unit 23 of the vulcanizer 20 to be a third temperature lower than the standard temperature. The third temperature may be the same value as the second temperature, or may be a different value. The third temperature condition is a condition that reduces productivity of retread tires, but results in a remaining durability index that is higher than the remaining durability index when the vulcanization process is performed under normal conditions.

[0063] The control unit 13 of the tire manufacturing management apparatus 10 may subdivide the third range according to the value of the remaining durability index within the third range and determine multiple stages of the third temperature. For example, the control unit 13 may determine multiple third temperatures that are lower than the standard temperature but different from each other when the remaining durability index is equal to or greater than 0.8 and less than 0.9 and when the remaining durability index is equal to or greater than 0.9 and less than 1.0.

[0064] Fig. 4 is a table diagram for explaining an example of the operation of the tire manufacturing management apparatus 10 of Fig. 1. Details of the acquisition process of step S102 of Fig. 2 and other processes executed by the tire manufacturing management apparatus 10 will be described with reference to Fig. 4.

[0065] For example, the control unit 13 of the tire manufacturing management apparatus 10 acquires table information such as that shown in Fig. 4 in advance and stores it in the storage unit 12. In the table information, for example, the remaining durability index, the first user, the second user, and the usage conditions are associated as information with each piece of identification information.

[0066] In this disclosure, a "first user" includes a user who used a tire that is the basis for a base tire having predetermined identification information. A "second user" is a user to whom a retreaded tire manufactured from a base tire having predetermined identification information is delivered, and includes a user who plans to use the retreaded tire. Each of the first user and the second user may be a business entity, such as a shipping company, or an individual. The first user and the second user may be the same or different from each other. In other words, a tire having predetermined identification information before and after tire retreading may be used by the same user or by different users.

[0067] In the present disclosure, the "usage conditions" include, for example, the value of the remaining durability index predicted to be consumed when the second user uses the retreaded tire. The usage conditions may be acquired based on history information indicating the frequency of past tire use by the second user. In the present disclosure, the control unit 13 of the tire manufacturing management device 10 may calculate the remaining durability index as a usage condition using an appropriate calculation formula from the history information, on the premise that such history information is acquired as data for each second user.

[0068] 2, the control unit 13 of the tire manufacturing management apparatus 10 acquires the predetermined identification information of the casing tire, and then refers to table information such as that shown in FIG. 4 stored in the storage unit 12. The control unit 13 reads out the remaining durability index associated with the acquired predetermined identification information. As a result, the control unit 13 acquires the remaining durability index of the casing tire corresponding to the predetermined identification information in step S102 of FIG. 2.

[0069] The process of acquiring the remaining durability index in step S102 of Fig. 2 is not limited to the above. For example, in the table information shown in Fig. 4, the remaining durability index does not have to be explicitly associated with the identification information. In this case, the control unit 13 of the tire manufacturing management apparatus 10 may acquire the usage history by the first user of a vehicle that was fitted with a tire that is the basis of a casing tire having predetermined identification information, i.e., past driving data of the vehicle, and estimate the remaining durability index from the acquired driving data. Alternatively, the control unit 13 may acquire the remaining durability index of the casing tire having predetermined identification information as a fixed value for each first user.

[0070] In addition to or instead of the above processing, the control unit 13 of the tire manufacturing management device 10 may obtain the usage conditions when the manufactured retreaded tire is used by a second user, and determine the vulcanization temperature conditions based on the usage conditions in addition to the remaining durability index.

[0071] For example, when the control unit 13 of the tire manufacturing management apparatus 10 acquires predetermined identification information of a casing tire in step S101 of FIG. 2, it refers to table information such as that shown in FIG. 4 stored in the memory unit 12. The control unit 13 reads out the remaining durability index and usage conditions associated with the acquired predetermined identification information. As a result, the control unit 13 acquires the remaining durability index and usage conditions of the casing tire corresponding to the predetermined identification information. The control unit 13 may determine the vulcanization temperature conditions based on the usage conditions in addition to the acquired remaining durability index.

[0072] For example, when the acquired remaining durability index value is 1.0, but the second user uses the tires frequently and the usage conditions are 1.2, the control unit 13 may determine a temperature condition lower than the normal conditions as the vulcanization temperature condition. In this way, the control unit 13 may adjust the vulcanization process in the vulcanization device 20 so that the remaining durability index, which is 1.0 when the vulcanization process is performed under the normal conditions, becomes 1.2 based on the vulcanization temperature condition.

[0073] For example, when the acquired remaining durability index value is 1.4 and the usage conditions are 1.2, the control unit 13 may determine a temperature condition higher than the normal conditions as the vulcanization temperature condition. In this way, the control unit 13 may adjust the vulcanization process in the vulcanization device 20 so that the remaining durability index, which is 1.4 when the vulcanization process is performed under the normal conditions, becomes 1.2 based on the vulcanization temperature condition.

[0074] According to the above-described embodiment, the production of retread tires can be optimized. The tire manufacturing management device 10 determines the vulcanization temperature conditions for the vulcanization process based on the acquired remaining durability index and outputs the determined conditions to the vulcanization device 20. This allows the tire manufacturing management device 10 to determine appropriate vulcanization temperature conditions according to the remaining durability index of the casing tire. For example, the tire manufacturing management device 10 can determine the normal vulcanization temperature conditions to contribute to the production of retread tires with the remaining durability index acquired in step S102 of FIG. 2 . For example, the tire manufacturing management device 10 can determine the first temperature conditions as the vulcanization temperature conditions to obtain a lower remaining durability index than that obtained when the vulcanization process is performed under normal conditions, but can instead contribute to improving the productivity of retread tires. For example, the tire manufacturing management device 10 can determine the second or third temperature conditions as the vulcanization temperature conditions to contribute to obtaining a higher remaining durability index than that obtained when the vulcanization process is performed under normal conditions, but at the cost of reducing the productivity of retread tires.

[0075] The tire manufacturing management device 10 determines at least the temperature conditions inside the base tire in the mold as the vulcanization temperature conditions. In this way, the tire manufacturing management device 10 contributes to the control of heating from the inside of the base tire by the vulcanizer 20, and can shorten the time for the vulcanization process by the vulcanizer 20. By performing the vulcanization process based on the temperature conditions inside the base tire determined by the tire manufacturing management device 10, the vulcanizer 20 can shorten the vulcanization time compared to when heating from the inside is not performed.

[0076] When the tire manufacturing management device 10 determines that the remaining durability index when the vulcanization process is performed under normal conditions is within the first reference range or the second reference range, it determines the normal conditions as the vulcanization temperature conditions. This allows the tire manufacturing management device 10 to contribute to the production of retread tires in a state that can be used up just once or that can be retreaded only once during the lifespan from the start of use to the end of the lifespan.

[0077] When the tire manufacturing management device 10 determines that the remaining durability index is within the first range, it determines the first temperature condition, which is higher than the normal condition, as the vulcanization temperature condition. As a result, when the value of the remaining durability index is within the reference range, the tire manufacturing management device 10 can use the difference from the reference range to consume more durability by heating at a higher temperature in the vulcanization process, thereby contributing to shortening the vulcanization time. The tire manufacturing management device 10 can determine vulcanization temperature conditions that prioritize productivity when manufacturing retreaded tires, contributing to improving the efficiency of retreaded tire manufacturing. For example, the tire manufacturing management device 10 can adjust the vulcanization process so that the remaining durability index, which is 1.5 when the vulcanization process is performed under normal conditions, becomes 1.0 based on the vulcanization temperature condition. The tire manufacturing management device 10 can also contribute to shortening the vulcanization time based on a vulcanization process at a higher temperature that consumes durability equivalent to a difference of 0.5.

[0078] When the tire manufacturing management device 10 determines that the remaining durability index is within the second range, it determines the second temperature condition, which is lower than the normal condition, as the vulcanization temperature condition. In this way, when the remaining durability index value is close to the reference range, the tire manufacturing management device 10 can compensate for the difference from the reference range by reducing the consumption of durability through heating at a lower temperature in the vulcanization process, thereby contributing to improving the durability of the retreaded tire. The tire manufacturing management device 10 can determine vulcanization temperature conditions that prioritize durability when manufacturing retreaded tires, thereby increasing the number of times the retreaded tire can be used. For example, the tire manufacturing management device 10 can adjust the vulcanization process so that the remaining durability index, which is 1.8 when the vulcanization process is performed under normal conditions, becomes 2.0 based on the vulcanization temperature condition. The tire manufacturing management device 10 can also compensate for the difference of 0.2, increasing the number of times the tire can be used from one under normal conditions to two. As a result, the tire manufacturing management device 10 can also improve the customer value and social value of retreaded tires.

[0079] When the tire manufacturing management device 10 determines that the remaining durability index is within the third range, it determines the third temperature condition, which is lower than the normal condition, as the vulcanization temperature condition. In this way, when the remaining durability index value is close to the reference range, the tire manufacturing management device 10 can compensate for the difference from the reference range by reducing the consumption of durability through heating at a lower temperature in the vulcanization process, thereby contributing to improving the durability of the retreaded tire. The tire manufacturing management device 10 can determine vulcanization temperature conditions that prioritize durability when manufacturing retreaded tires, thereby increasing the number of times the retreaded tire can be used. For example, the tire manufacturing management device 10 can adjust the vulcanization process so that the remaining durability index, which is 0.8 when the vulcanization process is performed under normal conditions, becomes 1.0 based on the vulcanization temperature condition. The tire manufacturing management device 10 can also compensate for the difference of 0.2 and increase the number of times the tire can be used under normal conditions to one. As a result, the tire manufacturing management device 10 can also improve the customer value and social value of retreaded tires.

[0080] The tire manufacturing management device 10 acquires the usage conditions when the manufactured retreaded tire is used by the second user, and determines the vulcanization temperature conditions based on the usage conditions as well as the remaining durability index. This allows the tire manufacturing management device 10 to contribute to manufacturing retreaded tires with an appropriate remaining durability index tailored to the second user. The tire manufacturing management device 10 can improve the suitability of the remaining durability index of the retreaded tire for the second user.

[0081] Although the present disclosure has been described based on the drawings and examples, it should be noted that those skilled in the art can make various modifications and changes based on the present disclosure. Therefore, it should be noted that these modifications and changes are included in the scope of the present disclosure. For example, the functions included in each configuration or step can be rearranged so as not to be logically inconsistent, and multiple configurations or steps can be combined or divided into one.

[0082] For example, a general-purpose electronic device such as a smartphone or a computer can be configured to function as the tire manufacturing management device 10 according to the embodiment described above. Specifically, a program describing the processing content for realizing each function of the tire manufacturing management device 10 according to the embodiment is stored in the memory of the electronic device, and the program is read and executed by a processor of the electronic device. Therefore, the present disclosure can also be realized as a program executable by a processor.

[0083] Alternatively, the present disclosure may be realized as a non-transitory computer-readable medium storing a program that can be executed by one or more processors to cause the tire manufacturing management device 10 according to one embodiment to execute each function, etc. It should be understood that these are also encompassed within the scope of the present disclosure.

[0084] In the above embodiment, the tire manufacturing management apparatus 10 is described as outputting the determined vulcanization temperature conditions to the vulcanization apparatus 20, but this is not limiting. The tire manufacturing management apparatus 10 may output the determined vulcanization temperature conditions to any other apparatus other than the vulcanization apparatus 20. For example, the tire manufacturing management apparatus 10 may cause the other apparatus to output the determined vulcanization temperature conditions as information and notify the user. For example, the tire manufacturing management apparatus 10 may cause the other apparatus to display the determined vulcanization temperature conditions on a screen or the like of the other apparatus.

[0085] In the above embodiment, the tire manufacturing management device 10 determines at least the temperature condition inside the base tire in the mold as the vulcanization temperature condition, but this is not limited to this. The tire manufacturing management device 10 may determine only the temperature condition outside the base tire in the mold as the vulcanization temperature condition.

[0086] In the above embodiment, when the tire manufacturing management device 10 determines that the remaining durability index when the vulcanization process is performed under normal conditions is within the first reference range or the second reference range, the tire manufacturing management device 10 determines the normal conditions as the vulcanization temperature conditions. However, the present invention is not limited to this. The number of reference ranges used to determine the remaining durability index may be one, or may be three or more.

[0087] In the above embodiment, when the remaining durability index is determined to be within the first range, the tire manufacturing management device 10 determines that the first temperature condition, which is higher than the normal temperature condition, is the vulcanization temperature condition. However, the present invention is not limited to this. The tire manufacturing management device 10 may also determine that the temperature condition, which is lower than the normal temperature condition, is the vulcanization temperature condition.

[0088] In the above embodiment, when the remaining durability index is determined to be within the second range, the tire manufacturing management device 10 determines the second temperature condition, which is lower than the normal temperature condition, as the vulcanization temperature condition. However, the present invention is not limited to this. The tire manufacturing management device 10 may also determine the temperature condition, which is higher than the normal temperature condition, as the vulcanization temperature condition.

[0089] In the above embodiment, the tire manufacturing management apparatus 10 executes the determination process for the remaining durability index based on the first reference range, the second reference range, the first range, the second range, and the third range, but is not limited to this. The number of ranges used in the determination process for the remaining durability index and the boundary values ​​of each range may be arbitrarily configured so that the tire manufacturing management apparatus 10 can optimize the production of retread tires.

[0090] In the above embodiment, the remaining durability index is described as being expressed as a numerical value such as 1.0, for example, but is not limited to this. The remaining durability index may be expressed as a percentage of the remaining durability when the new condition is 100%, for example. In this case, the tire manufacturing management device 10 may determine the vulcanization temperature conditions based on the following arithmetic expression: (remaining durability index) - (remaining durability index consumed by the second user) = (remaining durability index available for consumption in the vulcanization process). That is, the tire manufacturing management device 10 may combine the remaining durability index consumed in the vulcanization process and the remaining durability index consumed by the second user due to vehicle travel, etc., into an arithmetic expression that takes these into account equally. As an example, if the remaining durability index of a casing tire is 60% and the remaining durability index consumed by the second user is 40%, the tire manufacturing management device 10 may determine the vulcanization temperature conditions such that the remaining 20% ​​is consumed completely.

[0091] In the above embodiment, the tire manufacturing management device 10 acquires the usage conditions when a user uses a manufactured retreaded tire and determines the vulcanization temperature conditions based on the usage conditions in addition to the remaining durability index. However, the present invention is not limited to this. The tire manufacturing management device 10 does not have to execute the acquisition process and determination process related to the usage conditions.

[0092] In the above embodiment, the tire manufacturing management system 1 is configured so that the tire manufacturing management device 10 and the vulcanizing device 20 are communicably connected to each other via the network 30, but this is not limited to this. The tire manufacturing management device 10 and the vulcanizing device 20 may be communicably connected to each other directly without using the network 30. Alternatively, the tire manufacturing management device 10 and the vulcanizing device 20 are not limited to being configured as separate devices located at different locations, but may be configured as an integrated unit. For example, the tire manufacturing management device 10 may constitute a part of the vulcanizing device 20. [Industrial Applicability]
