Summary of the Invention

Problems to be Solved by the Invention

[0004] The inventor of the present invention wants to effectively utilize the unused puncture repair kit for tires.

Means for Solving the Problems

[0005] The tire repair kit recycling method disclosed herein includes an acquisition step and a classification step. In the acquisition step, information is obtained that can identify at least the manufacturing lot of the tire repair kit containing the tire repair fluid. In the classification step, the tire repair fluid recycling method is classified based on the information that can identify the manufacturing lot. [Effects of the Invention]

[0006] According to the recycling method, tire repair fluid can be put to good use. [Brief explanation of the drawing]

[0007] [Figure 1] Figure 1 is a schematic diagram of tire repair kit 1. [Figure 2] Figure 2 is a block diagram of the tire repair kit management device 30. [Figure 3] Figure 3 is a flowchart illustrating the recycling method for tire repair kits. [Figure 4] Figure 4 is a graph showing an example of the relationship between the elapsed time and the weight-average molecular weight of natural rubber. [Modes for carrying out the invention]

[0008] One embodiment of the present invention will be described below with reference to the drawings. However, the present invention is not limited to the following embodiments. Each drawing is schematic and does not necessarily reflect the actual object. Furthermore, each drawing is merely an example and does not limit the present invention unless specifically mentioned. Also, components and parts that perform the same function are appropriately denoted by the same reference numerals, and redundant explanations are omitted.

[0009] <Puncture Repair Kit 1> Figure 1 is a schematic diagram of tire repair kit 1. Tire repair kit 1 is a kit for emergency tire repair in the event of a puncture. Tire repair kit 1 may be kept inside a vehicle. Tire repair kit 1 is assigned an identifier 2, which is linked to the information of tire repair kit 1. Although not particularly limited, identifier 2 may be a two-dimensional code such as a matrix code or a stack code. Although not particularly limited, identifier 2 is attached to the bottle 12, which will be described later. Note that identifier 2 is not particularly limited as long as it is linked to the information of tire repair kit 1. Identifier 2 may be, for example, something that can be recognized by sight, etc. Identifier 2 may be, for example, a list of numbers, letters, symbols, etc.

[0010] As shown in Figure 1, the tire repair kit 1 includes a tire repair fluid 10 contained in a bottle 12 and a compressor 20. The tire repair fluid 10 may contain natural rubber and an aqueous propylene glycol solution. The components of the tire repair fluid 10 are not limited to natural rubber and an aqueous propylene glycol solution.

[0011] Bottle 12 is provided with a supply port 14 and a discharge port 16. The discharge port 16 is connected to the air valve of the punctured tire via a tube (not shown). A compressor 20 is connected to the supply port 14. Compressed air from the compressor 20 is supplied into bottle 12 from the supply port 14. Compressed air and tire repair fluid 10 are mixed and discharged from the discharge port 16. As a result, the punctured tire is filled with compressed air and injected with tire repair fluid 10. By driving the vehicle for a predetermined time in this state, the tire repair fluid 10 spreads inside the tire, and the tire repair fluid 10 dissolves the rubber component on the inner wall surface of the tire. The tire repair fluid 10 containing the dissolved rubber component seals the puncture from the inside. This provides emergency repair of the tire puncture.

[0012] By the way, the natural rubber contained in tire repair kit 1 deteriorates over time. Therefore, tire repair kit 1 needs to be replaced with a new one periodically, even if it is not used.

[0013] The recycling method for tire repair kits can be implemented by the tire repair kit management device 30. The recycling method for tire repair kits will be described below, along with the configuration of the tire repair kit management device 30.

[0014] Figure 2 is a block diagram of the tire repair kit management device 30. As shown in Figure 2, the tire repair kit management device 30 includes a control device 30a. The configuration of the control device 30a is not particularly limited. The control device 30a may be, for example, a microcomputer. The control device 30a includes, for example, an I / F, a CPU, ROM, and RAM. The tire repair kit management device 30 may be implemented by a single computer or by the cooperation of multiple computers. The tire repair kit management device 30 may be implemented by, for example, a server in a client-server system or by cloud computing. The entity managing and operating the tire repair kit management device 30 is not particularly limited, but it may be managed by, for example, a tire sales company.

[0015] The control device 30a of the tire repair kit management device 30 includes a communication unit 31, a storage unit 32, an ID acquisition unit 33, a lot acquisition unit 34, an elapsed time acquisition unit 35, an estimation unit 36, a classification unit 37, a presentation unit 38, and a benefit granting unit 39. In this embodiment, the ID acquisition unit 33 and the lot acquisition unit 34 can function as lot information acquisition units 33 and 34. Each of the units 31 to 39 of the control device 30a may be implemented by one or more processors or incorporated into a circuit.

[0016] The communication unit 31 is configured to communicate with the store terminal 40. The store terminal 40 is installed in each store that collects the tire repair kit 1, such as tire sales companies and vehicle manufacturers. The store terminal 40 is a terminal that reads the identifier 2 of the tire repair kit 1. The store terminal 40 may be a portable terminal, a mobile terminal, or a terminal fixed to each facility. The store terminal 40 comprises a communication unit 41, a reading unit 42, and an ID acquisition unit 43. The reading unit 42 may be a camera that reads the identifier 2 of the tire repair kit 1. The reading unit 42 captures an image of the identifier 2 of the tire repair kit 1. The ID acquisition unit 43 acquires the ID of the tire repair kit 1 from the identifier 2 captured by the reading unit 42. The ID acquired by the ID acquisition unit 43 is transmitted to the tire repair kit management device 30 via the communication unit 41. Here, the ID is a number used to identify the tire repair kit 1. An ID is assigned individually to each tire repair kit 1. The ID is assigned, for example, during the manufacturing of the tire repair kit 1. The ID acquisition unit 43 is not limited to the form described above. The ID acquisition unit 43 can be appropriately selected depending on the form of the identifier 2. For example, if the identifier 2 is recognizable by sight or other means, the ID acquisition unit 43 may be an input receiving unit that acquires the ID through input from a keyboard, touch panel, etc. Alternatively, the user of the store terminal 40 may input information about the identifier 2, and the ID acquisition unit 43 may acquire the ID as a result.

[0017] When an ID is transmitted from the store terminal 40 to the tire repair kit management device 30, the tire repair kit management device 30 executes a process (acquisition step S10) to acquire information that can identify the manufacturing lot.

[0018] Figure 3 is a flowchart of a method for recycling a tire repair kit. As shown in Figure 3, the method for recycling a tire repair kit disclosed herein includes an acquisition step S10 and a sorting step S20.

[0019] The acquisition step S10 is a step of acquiring information that can identify at least the manufacturing lot of the puncture repair kit 1. Here, the "information that can acquire the manufacturing lot" is not particularly limited as long as it is information associated with the manufacturing lot. The "information that can acquire the manufacturing lot" may be, for example, an ID associated with the manufacturing lot, an identifier 2 attached to the puncture repair kit 1, or the manufacturing lot itself. The acquisition step S10 includes an ID acquisition step S12 of acquiring an ID and a manufacturing lot acquisition step S14 of acquiring the manufacturing lot.

[0020] In this embodiment, the information that can identify the manufacturing lot of the puncture repair kit 1 is an ID. As described above, the ID is assigned at the time of manufacturing the puncture repair kit 1. The ID is associated with the manufacturing lot at the time of manufacturing the puncture repair kit 1. The ID and the manufacturing lot of each puncture repair kit 1 are stored, for example, in the storage unit 32 of the puncture repair kit management device 30. In the ID acquisition step S12, the ID acquisition unit 33 of the control device 30a receives the ID of the puncture repair kit 1 transmitted from the store terminal 40 via the communication unit 31. In the manufacturing lot acquisition step S14, the lot acquisition unit 34 of the control device 30a refers to the storage unit 32 and acquires the manufacturing lot from the ID of the puncture repair kit 1. In the puncture repair kit management device 30, when the manufacturing lot is acquired, subsequently, a process of classifying the recycling method of the puncture repair liquid 10 (classification step S20) is executed.

[0021] The classification step S20 is a step of classifying the recycling method of the puncture repair liquid 10 based on the information that can identify the manufacturing lot. In this embodiment, the information that can identify the manufacturing lot is the manufacturing lot itself.

[0022] In the classification step S20, the state of the natural rubber contained in the puncture repair liquid may be estimated based on the information that can identify the manufacturing lot. In the classification step S20, the recycling method of the puncture repair liquid 10 may be classified according to the state of the natural rubber. By classifying based on the state of the natural rubber that easily deteriorates in the puncture repair liquid 10, the puncture repair liquid 10 is easily recycled for more appropriate uses.

[0023] In this embodiment, the classification step S20 includes an elapsed time acquisition step S22, a molecular weight estimation step S24, a recycling method classification step S26, and a presentation step S28.

[0024] The elapsed time acquisition step S22 is a step of acquiring the elapsed time from the production time of the puncture repair liquid 10 based on the production lot of the puncture repair kit 1. In the storage unit 32, the production date of each puncture repair kit 1 is stored together with the production lot. The elapsed time acquisition unit 35 acquires the elapsed time from the production date of the puncture repair liquid 10 from the production date stored together with the production lot and the current date.

[0025] The molecular weight estimation step S24 is a step of estimating the weight average molecular weight of the natural rubber contained in the puncture repair liquid 10 based on the production lot of the puncture repair kit 1. In the knowledge of the present inventor, the natural rubber contained in the puncture repair liquid 10 deteriorates over time. The natural rubber has its bonds within the polymer broken as time passes, and the molecular weight (weight average molecular weight) becomes smaller. In the knowledge of the present inventor, if the elapsed time from the production time is the same for the puncture repair liquid, the decrease in the weight average molecular weight of the natural rubber is substantially the same. The relationship between the elapsed time and the weight average molecular weight of the natural rubber can be obtained in advance as an estimated value by tests, simulations, etc.

[0026] In the molecular weight estimation step S24, the estimation unit 36 acquires the elapsed time based on the production lot of the puncture repair kit 1. Further, the estimation unit 36 estimates the weight average molecular weight based on the database DB stored in the storage unit 32 and the elapsed time. Thereby, the accuracy of the estimation of the weight average molecular weight of the natural rubber can be improved. When the weight average molecular weight of the natural rubber contained in the puncture repair liquid 10 is estimated, subsequently, the recycling method is classified.

[0027] In the recycling method classification step S26, the classification unit 37 classifies the recycling method of the tire repair fluid 10 according to its weight-average molecular weight. In other words, the natural rubber contained in the tire repair fluid 10 is recycled for different purposes according to its weight-average molecular weight. The recycling methods are, for example, divided into multiple uses according to the weight-average molecular weight.

[0028] Here, the classification unit 37 classifies the recycling methods for the tire repair fluid 10 such that the higher the weight-average molecular weight of the natural rubber contained in the tire repair fluid 10, the more likely it is to be recycled into materials requiring high strength. Natural rubber with a high weight-average molecular weight can be used, for example, as a backing material for artificial turf.

[0029] Furthermore, the classification unit 37 classifies the recycling method of the tire repair fluid 10 so that the lower the weight-average molecular weight of the natural rubber contained in the tire repair fluid 10, the more likely it is to be recycled into materials where adhesiveness is required. Natural rubber with a low weight-average molecular weight can be used, for example, as a material for rubber adhesives. In this way, even tire repair fluid 10 that has deteriorated to a certain extent can be effectively recycled.

[0030] In presentation step S28, the presentation unit 38 presents the recycling methods classified by the classification unit 37 as recycling methods for the tire repair fluid 10. The tire repair fluid 10 can be collected by a recycling company or the like. The natural rubber is recycled according to the recycling method classified by the classification unit 37. Natural rubber and propylene glycol aqueous solution are separated from the collected tire repair fluid 10. The propylene glycol aqueous solution may be recycled, for example, into newly manufactured tire repair fluid or tire repair kits. The bottle unit of the tire repair kit 1 can be crushed, washed, and recycled again as bottle material. The compressor 20 can be disassembled, dissolved into its parts, and recycled again as compressor material.

[0031] In the embodiment described above, the method for recycling a tire repair kit includes an acquisition step S10 and a classification step S20. The acquisition step S10 is a step of acquiring information that can identify at least one manufacturing lot of the tire repair kit 1. The classification step S20 is a step of classifying the recycling method of the tire repair fluid 10 based on the information that can identify the manufacturing lot. The condition of the tire repair fluid 10 may differ depending on the manufacturing lot. According to this manufacturing method, the recycling application is appropriately selected according to the manufacturing lot. As a result, the tire repair fluid 10 can be effectively utilized.

[0032] In the embodiment described above, in the classification step S20, the weight-average molecular weight of the natural rubber contained in the tire repair fluid 10 is estimated based on information that can identify the manufacturing lot (molecular weight estimation step S24). Also in the classification step S20, the recycling method of the tire repair fluid 10 is classified according to the weight-average molecular weight (recycling method classification step S26). The physical properties of natural rubber are highly dependent on the weight-average molecular weight. By classifying the recycling method according to the weight-average molecular weight of the natural rubber, the tire repair fluid 10 is more easily recycled to a more appropriate use.

[0033] Note that the amount of natural rubber contained in the tire repair fluid 10 may vary depending on the product. Figure 4 is a graph showing an example of the relationship between the elapsed time and the weight-average molecular weight of the natural rubber. Figure 4 shows the change over time in the weight-average molecular weight of the natural rubber contained in two types of tire repair fluids 10A and 10B. The weight-average molecular weight of the natural rubber contained in tire repair fluids 10A and 10B decreases exponentially over time. Here, tire repair fluids 10A and 10B are different products. The decrease in weight-average molecular weight of the natural rubber contained in tire repair fluid 10A is slower than that of the natural rubber contained in tire repair fluid 10B. The storage unit 32 of the control device 30a is equipped with a database DB that records the relationship between the elapsed time from the time of manufacture of the tire repair fluid and the estimated value of the weight-average molecular weight of the natural rubber. Note that in the configuration shown in Figure 4, the relationship between the weight-average molecular weight of the natural rubber contained in two types of tire repair fluids 10A and 10B and the elapsed time is shown. The database (DB) may store the relationship between the weight-average molecular weight of natural rubber and the elapsed time for one type of tire repair fluid. The database (DB) may also store the relationship between the weight-average molecular weight of natural rubber and the elapsed time for many more types of tire repair fluids. By classifying recycling methods based on weight-average molecular weight, natural rubber contained in different products can be used for similar applications even if they are in similar degradation states.

[0034] In the classification step S20, the tire repair fluid 10 may be ranked according to its weight-average molecular weight. For example, the higher the weight-average molecular weight, the higher the recycling value of the natural rubber. The tire repair fluid 10 may be ranked such that the higher the weight-average molecular weight, the higher the rank. The presentation step S28 may include a reward granting step in which rewards are given to the owner of the tire repair kit 1 according to the rank. In the presentation step S28, the reward granting unit 39 grants rewards to the owner of the tire repair kit 1 according to the rank. The rewards given to the owner may be, for example, points, coupons, vouchers, or the acquisition of goods. The rewards given to the owner may be given electronically via the owner's terminal or the like. This motivates the owner of the tire repair kit 1 to bring the tire repair kit 1 to a store before the deterioration of the tire repair fluid 10 progresses to its limit. As a result, the tire repair fluid 10 is more likely to be recovered containing natural rubber with a relatively high weight-average molecular weight, which has a relatively high recycling value.

[0035] In the classification step S20, the recycling method does not necessarily have to be classified based on the weight-average molecular weight of natural rubber. In the classification step S20, the recycling method of the tire repair fluid 10 may be classified based on the time elapsed since the time of manufacture. As mentioned above, the tire repair fluid 10 deteriorates according to the time elapsed since the time of manufacture. The recycling applications of the tire repair fluid 10 may be predetermined according to the time elapsed since the time of manufacture. Using this method, the recycling method can be classified more simply, for example, when recycling only one type of tire repair fluid 10.

[0036] In this embodiment, the ID of the tire repair kit 1 is acquired by the store terminal 40 and transmitted to the tire repair kit management device 30, but the system is not limited to this configuration. For example, the identifier 2 read by the store terminal 40 may be transmitted to another terminal. The ID may be acquired by the other terminal and transmitted to the tire repair kit management device 30. The identifier 2 or its data read by the store terminal 40 may be transmitted to the tire repair kit management device 30. In this case, the ID may be acquired by the tire repair kit management device 30. Furthermore, the manufacturing lot may be acquired directly by the tire repair kit management device 30 without acquiring the ID.

Furthermore, the various configurations described can be combined as appropriate, provided that they do not interfere with one another.
