Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, vibration isolation parts may require maintenance or the like depending on the degree of deterioration of their vibration isolation rubber. Therefore, conventional vibration isolation parts sometimes have information on the manufacturing date described thereon, and the elapsed time from that manufacturing date is used as a guideline for maintenance. However, for example, depending on the installation location of the vibration isolation parts in railway vehicles or construction machinery, it may be difficult to visually confirm the information described on the vibration isolation parts. That is, it has sometimes been difficult to appropriately manage the vibration isolation parts used in railway vehicles or construction machinery.

[0005] The disclosed technology provides a vibration isolation part for a railway vehicle or construction machinery, a management system for vibration isolation parts, and a manufacturing method for vibration isolation parts that enable more appropriate management of vibration isolation parts having vibration isolation rubber used in railway vehicles or construction machinery.

Means for Solving the Problems

[0006] One aspect of the disclosed technology is a vibration damping component for railway vehicles or construction machinery, comprising a base material, a main rubber portion provided on the base material and functioning as a cushioning material in railway vehicles or construction machinery, a wireless tag having a storage portion for storing information relating to the main rubber portion, and a tag housing portion provided on the base material separately from the main rubber portion and made of rubber or resin for housing the wireless tag.

[0007] In this vibration-damping component, even when used in railway vehicles or construction machinery, the main rubber part, which acts as a vibration-damping rubber, can be managed based on information obtained from wireless tags. Furthermore, the tag housing is located separately from the main rubber part. Therefore, deformation of the main rubber part when it functions as a cushioning material is prevented from affecting the tag housing. In other words, even if a crack occurs in the main rubber part, it is prevented from spreading to the tag housing. Also, if the tag housing is deformed, the wireless tag, which can act as a foreign object and hinder the movement of the tag housing, may cause cracks to form inside the tag housing at the edges of the wireless tag. However, in this vibration-damping component, even if the main rubber part deforms, that deformation is not transmitted to the tag housing. In other words, deformation of the tag housing is suppressed. Therefore, cracks in the tag housing will not occur due to the main rubber part functioning as a cushioning material. That is, it is prevented that a damaged tag housing will not be able to properly hold the wireless tag, and furthermore, that the wireless tag will not fall out of the damaged tag housing. This allows for the accurate acquisition of information from wireless tags over the long term. Consequently, it enables more appropriate management of vibration-damping components that have a rubber body.

[0008] Another aspect of the disclosed technology is a vibration isolation component management system for railway vehicles or construction machinery, comprising the above-mentioned vibration isolation component, a reader device capable of communicating with a wireless tag, and a server capable of managing information related to the vibration isolation component, wherein the reader device has an information acquisition reader device capable of acquiring information stored in the storage unit of the wireless tag by communicating with the wireless tag, and the server stores the information acquired from the information acquisition reader device in association with the vibration isolation component on which the wireless tag from which the information was acquired is installed.

[0009] Another aspect of the disclosed technology is a method for manufacturing a vibration-damping component for railway vehicles or construction machinery, comprising a base material and a main rubber portion provided on the base material and functioning as a cushioning material in railway vehicles or construction machinery, wherein the vibration-damping component comprises a wireless tag having a storage portion for storing information relating to the main rubber portion, and a tag housing portion provided on the base material away from the main rubber portion and composed of rubber or resin for housing the wireless tag, wherein the tag housing portion is formed by placing an uncrosslinked rubber material or liquid resin material covering the wireless tag in a housing portion region on the base material away from the main portion region where the main rubber portion is provided, and crosslinking the uncrosslinked rubber material or curing the liquid resin material placed in the housing portion region.

Embodiments for Carrying Out the Invention

[0012] Hereinafter, embodiments embodying the present disclosed technology will be described in detail with reference to the accompanying drawings.

[0013] Figure 1 shows the vibration isolation component A according to this embodiment. The vibration isolation component A according to this embodiment is for railway vehicles. The vibration isolation component A includes a base material 110, a main body rubber part 120, and a tag housing part 130. In this embodiment, metal is adopted as the material of the base material 110. The main body rubber part 120 is provided on the base material 110. More specifically, the main body rubber part 120 is provided in the main body part region 111 of the base material 110. The main body rubber part 120 is a vibration isolation rubber that functions as a shock absorber in the railway vehicle where the vibration isolation component A is provided. In the vibration isolation component A shown in Figure 1, the main body rubber part 120 is provided on the upper surface of the base material 110. On the lower surface side of the base material 110, a fixing part 140 for fixing the vibration isolation component A to the railway vehicle is provided.

[0014] The tag housing part 130 is provided on the base material 110, similar to the main body rubber part 120. However, the tag housing part 130 is provided separately from the main body rubber part 120. More specifically, the tag housing part 130 is provided in the housing part region 112 that is separated from the main body part region 111 of the base material 110. In this embodiment, rubber is adopted as the material of the tag housing part 130. The type of rubber of the tag housing part 130 may be the same as or different from that of the main body rubber part 120.

[0015] An RF tag T, which is an IC tag related to RFID (Radio Frequency Identification), is housed in the tag housing part 130. As shown in Figure 2, the RF tag T includes a control circuit 50, an antenna 51, and a memory 55. The control circuit 50 operates, for example, when communication from the reader device D to the antenna 51 is started, reads the information stored in the memory 55, and can perform control to transmit the read information to the reader device D via the antenna 51. Communication between the antenna 51 of the RF tag T and the reader device D is possible using radio waves or electromagnetic waves. That is, the RF tag T is a wireless tag that performs wireless communication.

[0016] The memory 55 is a storage part that stores predetermined information. The memory 55 of this embodiment has a management information storage area 56, a status information storage area 57, and a communication position passing information storage area 58.

[0017] The management information storage area 56 is an area for storing management information. The management information includes at least one of the following: manufacturer information, manufacturing date information, replacement date information, and identification information. Manufacturer information is information indicating the business operator that manufactured the main rubber part 120. Manufacturing date information is information indicating the manufacturing date of the main rubber part 120. Replacement date information is, for example, information indicating the time when replacement of vibration-damping component A is recommended, in accordance with the deterioration of the main rubber part 120's function as a cushioning material when vibration-damping component A has been used under general conditions. Identification information is information that can be used to manage vibration-damping component A, which has the main rubber part 120, separately from other vibration-damping components. Therefore, the management information is information relating to the main rubber part 120. The management information can be stored in memory 55, for example, at the time of manufacturing of vibration-damping component A.

[0018] The state information storage area 57 is an area for storing state information. The state information includes one of the following: displacement information related to the displacement of the main rubber part 120, temperature information indicating the temperature of the main rubber part 120, load information indicating the load applied to the main rubber part 120, and acceleration information related to the acceleration of the railway vehicle to which it is attached. The temperature information indicating the temperature of the main rubber part 120 is not limited to the temperature of the main rubber part 120 itself, but for example, the ambient temperature around the main rubber part 120 can be used. The load information indicating the load applied to the main rubber part 120 is not limited to the load applied to the main rubber part 120 itself, but for example, load values ​​measured around the main rubber part 120 can be used. Specifically, for example, the measured value of the load applied to the base material 110 on the side opposite to the main rubber part 120 can be used as load information. The degree of deterioration of the main rubber part 120 may differ depending on, for example, the input displacement, temperature, load, and the acceleration when the railway vehicle to which it is installed accelerates or decelerates. Furthermore, for example, the degree of deterioration of the main rubber part 120 may differ depending on the acceleration related to lateral swaying when the railway vehicle on which it is installed travels along a curve. Therefore, the condition information pertains to the main rubber part 120.

[0019] State information, such as displacement information, temperature information, load information, and acceleration information, can be acquired by a state information sensor C, which is a detection device capable of detecting these. Specifically, the state information sensor C is one of the following: a displacement meter that detects displacement information related to the displacement of the main body rubber part 120; a thermometer that detects temperature information indicating the temperature of the main body rubber part 120; a load cell that detects load information indicating the load applied to the main body rubber part 120; or an accelerometer that detects acceleration information related to the vertical, longitudinal, left-right, etc., of the railway vehicle.

[0020] The state information sensor C is connected to the control circuit 50. When the state information sensor C detects any of the following: displacement information, temperature information, load information, or acceleration information, the control circuit 50 acquires the detected information and stores it as state information in the state information storage area 57 of the memory 55.

[0021] The communication location passage information storage area 58 is an area for storing communication location passage information. The communication location passage information includes at least one of the following: information about the communication location and information indicating the number of times the communication location has been passed. The communication location is, simply put, location information indicating the location of a pre-installed reader device D. In other words, when a railway vehicle equipped with vibration damping components A passes the communication location of the reader device D, communication with the reader device D is performed by the antenna 51. When the antenna 51 communicates with the reader device D, the control circuit 50 can acquire the location information of the reader device D as information about the communication location. The information about the communication location can be stored in the reader device D and transmitted to the antenna 51. Furthermore, when the control circuit 50 passes the communication location of a specific reader device D, it can count the number of times communication has been performed with that specific reader device D and acquire that count value as information indicating the number of times the communication location has been passed.

[0022] Communication location passage information is information relating to the past movements of a railway vehicle. Therefore, communication location passage information is information relating to the main rubber part 120 installed on the railway vehicle. When the control circuit 50 acquires information relating to the communication location or information indicating the number of times the communication location has been passed, it stores that information as communication location passage information in the communication location passage information storage area 58 of the memory 55.

[0023] In this type of vibration-damping component A, it is possible to estimate when maintenance of the main rubber part 120 will be required based on the information stored in the memory 55 of the RF tag T. Therefore, it is unnecessary to visually check the information written on the component. In other words, even if the vibration-damping component A is installed in a location that is difficult to check visually, management information related to the main rubber part 120 can be obtained, for example. Thus, vibration-damping component A makes it possible to manage information related to the main rubber part 120, which is vibration-damping rubber, more appropriately.

[0024] Figure 3 is a schematic diagram of the management system 1 for the vibration isolation component A according to this embodiment. The vibration isolation component A in this embodiment is installed on a railway vehicle B. The railway vehicle B can travel on a track R. The management system 1 includes a first railway vehicle B1 and a second railway vehicle B2 as railway vehicles B. The management system 1 also includes a first vibration isolation component A1 installed on the first railway vehicle B1 and a second vibration isolation component A2 installed on the second railway vehicle B2 as vibration isolation component A.

[0025] Each vibration isolation component A has an RF tag T. The first vibration isolation component A1 has a first RF tag T1 as its RF tag T. The second vibration isolation component A2 has a second RF tag T2 as its RF tag T. In this embodiment, a semi-passive type (semi-active type) RF tag T is used. The first vibration isolation component A1 also has a first state information sensor C1 as its state information sensor C. The second vibration isolation component A2 has a second state information sensor C2 as its state information sensor C.

[0026] The state information sensor C only needs to be installed in a position where it can detect its target. Specifically, for example, a state information sensor C that is a displacement meter, thermometer, load cell, or accelerometer that acquires information about the main rubber part 120 can be installed on the main rubber part 120. Alternatively, for example, the state information sensor C may be fixed to the base material 110, or to the railway vehicle B on which the vibration-damping component A is mounted. The location where the state information sensor C is fixed should be determined appropriately according to the information to be detected. It should be noted that there may be multiple state information sensors C, each detecting different information.

[0027] A communication position R1 for the leader device D is provided on track R. Communication position R1 is a predetermined position on track R on which railway vehicle B travels. When railway vehicle B, which is equipped with vibration damping component A, passes communication position R1, the leader device D starts communicating with RF tag T. Through communication with RF tag T, the leader device D can receive information from RF tag T and transmit information to RF tag T.

[0028] Specifically, the reader device D can acquire management information, status information, and communication location information stored in the RF tag T's memory 55 through communication with the RF tag T. The reader device D can also transmit information regarding its own communication location R1 during communication with the RF tag T. Furthermore, in this semi-passive configuration, the RF tag T detects status information via the status information sensor C when communication from the reader device D occurs as the railway vehicle B passes the communication location R1. If an active type RF tag T is used, the detection of status information by the status information sensor C can be performed at any time, not just when the railway vehicle B passes the communication location R1.

[0029] Communication position R1 can be, for example, a position on track R for entering a depot for storing and maintaining railway vehicle B. Multiple reader devices D may be installed along track R. That is, there may be multiple communication positions R1 on track R. For example, based on information that railway vehicle B has passed through multiple communication positions R1, the usage distance of vibration-damping component A (the distance traveled by the railway vehicle B on which it is installed) can be calculated. Furthermore, if the communication position passage information is referenced together with the information of when it was acquired (for example, the date it was acquired), the actual usage period of vibration-damping component A can be calculated based on this information. Information on the acquisition timing of communication position passage information may be included in the communication position passage information, or it may be separate information. If the information on the acquisition timing of communication position passage information is treated as separate information from the communication position passage information, it is sufficient that it is managed in association with the communication position passage information.

[0030] Furthermore, the management system 1 includes a computer 10 belonging to user X, a computer 20 belonging to the administrator, and a server 30. User X is, for example, a business operator that owns and operates railway vehicle B equipped with vibration-damping component A. The administrator is a business operator that manages the maintenance, inspection, etc., of vibration-damping component A. User X may be the same business operator as the administrator, or a different business operator from the administrator. The user's computer 10, the administrator's computer 20, and the server 30 are interconnected via a network 2 such as the Internet.

[0031] The user's computer 10 includes a control unit 11 containing a CPU 12 and memory 13, a first communication IF 14, a second communication IF 15, and a user IF 16. Note that the control unit 11 is a general term encompassing the hardware and software used to control the user's computer 10, and does not necessarily represent a single piece of hardware actually present in the user's computer 10.

[0032] The CPU 12 executes various processes according to the program read from memory 13 and based on the operator's input. Memory 13 stores various programs, including the OS, and various data. The buffer provided by the CPU 12 is also an example of memory. An example of memory 13 is not limited to ROM, RAM, HDD, etc., built into the user's computer 10, but may also be a storage medium that the CPU 12 can read and write to.

[0033] The user interface 16 is an interface that has functions such as receiving input for the user to use the computer 10. The user interface 16 is, for example, a touch panel and includes hardware that displays a screen to inform the user of information and hardware that accepts user operations. The user interface 16 may also be a combination of a display and an operating unit such as a keyboard or mouse.

[0034] The first communication IF14 and the second communication IF15 are interfaces for communication with external devices. The first communication IF14 is connected to the reader device D and includes hardware for communicating with the reader device D. The second communication IF15 is connected to network 2 and includes hardware for communicating with server 30. The communication standards for the first communication IF14 and the second communication IF15 include Ethernet®, Wi-Fi®, and USB.

[0035] The memory 13 of the user's computer 10 stores the user application EX, folder A1 FA1, and folder A2 FA2. The user application EX is an application program that has functions for receiving and transmitting information related to vibration-damping component A via the first communication IF 14, the second communication IF 15, etc., and for viewing information related to vibration-damping component A. As a result, the user's computer 10 can use the user application EX to obtain the information acquired by the reader device D from the RF tag T through communication with the antenna 51.

[0036] The user application EX can store information acquired from the RF tag T in folders A1 FA1 and A2 FA2. Folder A1 FA1 is a folder that stores information acquired from the first RF tag T1 of the first vibration isolation component A1. Folder A2 FA2 is a folder that stores information acquired from the second RF tag T2 of the second vibration isolation component A2. Furthermore, the user application EX can transmit the information stored in folders A1 FA1 and A2 FA2 to the server 30 via the second communication IF15 and network 2.

[0037] The administrator's computer 20 includes a control unit 21 containing a CPU 22 and memory 23, a communication interface 24, and a user interface 26. The basic configuration and functions of the CPU 22, memory 23, communication interface 24, and user interface 26 are the same as those of the user's computer 10. The communication interface 24 is connected to network 2 and includes hardware for communicating with server 30.

[0038] The administrator's computer 20 stores the administrator application EY in its memory 23. The administrator application EY is an application program that has functions such as viewing information related to vibration-damping component A stored on the server 30 via the network 2. As a result, the administrator's computer 20 can view various information about vibration-damping component A by using the administrator application EY.

[0039] Server 30 includes a control unit 31 containing a CPU 32 and memory 33, a communication interface 34, and a user interface 36. The basic configuration and functions of the CPU 32, memory 33, communication interface 34, and user interface 36 are the same as those of the user's computer 10. The communication interface 34 is connected to network 2 and includes hardware for communicating with the user's computer 10 and the administrator's computer 20. Server 30 is a device capable of managing information related to vibration isolation component A.

[0040] The memory 33 of server 30 stores folders A1 FA1 and A2 FA2. Folders A1 FA1 and A2 FA2 are folders that store information obtained about the first vibration-damping component A1 and information obtained about the second vibration-damping component A2, respectively. In other words, information sent from the user's computer 10 via network 2 is copied and stored in folders A1 FA1 and A2 FA2, respectively. Furthermore, the administrator's computer 20 can access the information stored in folders A1 FA1 and A2 FA2 of server 30 via network 2.

[0041] In the vibration-damping component A of the management system 1 described above, the tag housing section 130 is provided separately from the main rubber section 120. Therefore, in railway vehicle B, deformation of the main rubber section 120 when it functions as a cushioning material is suppressed from affecting the tag housing section 130. In other words, even if a crack occurs in the main rubber section 120, it is suppressed from spreading to the tag housing section 130. Furthermore, if the tag housing section 130 deforms, since it houses RF tags T, which can act as foreign objects and hinder the movement of the tag housing section 130, there is a possibility that cracks may occur inside the tag housing section 130 from the edges of the RF tags T. However, in vibration-damping component A, even if the main rubber section 120 deforms, that deformation is not transmitted to the tag housing section 130. In other words, deformation of the tag housing section 130 is suppressed. Therefore, cracks will not occur in the tag housing section 130 due to the main rubber section 120 which functions as a cushioning material. In other words, the damaged tag housing 130 is prevented from properly holding the RF tag T, and furthermore, the RF tag T is prevented from falling out of the damaged tag housing 130. As a result, information can be properly acquired from the RF tag T over a long period of time. Consequently, the main rubber part 120, which is vibration-damping rubber, can be properly managed. In other words, it is possible to properly manage the vibration-damping component A having the main rubber part 120. In addition, since the tag housing 130 of the vibration-damping component A is not connected to the main rubber part 120, it is possible to prevent the main rubber part 120 from being affected when replacing the RF tag T inside the tag housing 130. As a result, for example, it is possible to reuse the vibration-damping component A in which only the RF tag T is damaged at low cost.

[0042] Furthermore, the volume of the tag housing section 130 is smaller than that of the main rubber section 120. The tag housing section 130 only needs to be large enough to accommodate the RF tag T, whereas the main rubber section 120, which functions as a cushioning material in the railway vehicle B, needs to be of a certain size. The small size of the tag housing section 130 helps to suppress its impact on other components of the vibration-damping part A, such as the main rubber section 120.

[0043] Furthermore, in the management system 1, the reader device D can obtain information stored in the memory 55 of the RF tag T of the vibration isolation component A by communicating with the RF tag T. Therefore, the reader device D functions as an information acquisition reader device that acquires information from the RF tag T. In addition, the server 30 stores information related to the main body rubber part 120 of the first vibration isolation component A1, obtained from the first RF tag T1 of the first vibration isolation component A1, in the A1 folder FA1 of the memory 33. The server 30 also stores information related to the main body rubber part 120 of the second vibration isolation component A2, obtained from the second RF tag T2 of the second vibration isolation component A2, in the A2 folder FA2 of the memory 33. In other words, the server 30 stores the information acquired by the reader device D in association with the vibration isolation component A on which the source RF tag T is installed. Therefore, the manager of the vibration isolation component A can grasp this information for each of the multiple vibration isolation component A. Thus, the main body rubber part 120 of each vibration isolation component A can be properly managed. In other words, it enables more appropriate management of the vibration-damping component A having a main rubber part 120. Furthermore, by properly managing information on vibration-damping component A, it becomes possible to plan the ordering and manufacturing of replacement vibration-damping component A. In addition, user X can plan and prepare for the cost of replacing vibration-damping component A. Note that the manner in which each piece of information is associated with vibration-damping component A is not limited to storage folders, but may be in other ways.

[0044] Furthermore, in the management system 1, a state information sensor C is provided on the vibration-damping component A. The RF tag T acquires the state information detected by the state information sensor C and stores it in the memory 55. The state information is information that changes depending on how the vibration-damping component A is used, and is also information that can affect the degree of deterioration of the main rubber part 120 of the vibration-damping component A. In this management system 1, the manager of the vibration-damping component A can estimate, for example, the degree of deterioration of the main rubber part 120 based on the state information, according to how it is used. This allows for more appropriate management of the main rubber part 120 of the vibration-damping component A. In other words, it makes it possible to manage the vibration-damping component A, which has a main rubber part 120, more appropriately. Also, depending on the information detected by the state information sensor C, it is possible to detect damage to the main rubber part 120 at an early stage. In addition, by acquiring data on the degree of deterioration according to the usage conditions based on the information detected by the state information sensor C, improvements to the vibration-damping component A can be carried out efficiently.

[0045] Furthermore, the reader device D is positioned at a location on the track R, which is the path traveled by the railway vehicle B equipped with the vibration-damping component A, with communication position R1 as the communication position R1. When the railway vehicle B equipped with the vibration-damping component A passes through communication position R1, the reader device D communicates with the RF tag T of the vibration-damping component A and can acquire information from the RF tag T. This allows for the automatic acquisition of information related to the main rubber part 120 of the vibration-damping component A when the railway vehicle B passes through communication position R1. Therefore, for example, workers performing inspection work on the railway vehicle B do not necessarily need to read the information from the RF tag T using the reader device D. Also, the communication position R1 can be predetermined by the placement of the reader device D. In other words, the management system 1 can systematically acquire information related to the main rubber part 120 of the vibration-damping component A in accordance with the railway vehicle B passing through the predetermined communication position R1. In this embodiment, information related to the main rubber part 120 of the vibration-damping component A can be systematically acquired in accordance with the railway vehicle B returning to the depot.

[0046] Furthermore, the reader device D is a state information reader device that communicates with the RF tag T of the vibration-damping component A when the railway vehicle B, which is equipped with the vibration-damping component A, passes through communication position R1, thereby causing the RF tag T to acquire state information detected by the state information sensor C. A semi-passive type RF tag T can be used for the reader device D that corresponds to this state information reader device. By using a semi-passive type RF tag T, it is less expensive than using an active type. This makes it possible to reduce the cost of the vibration-damping component A while automatically acquiring and managing information from the main rubber part 120 of the vibration-damping component A.

[0047] Furthermore, the reader device D is a reader device for passage information that, when a railway vehicle B equipped with vibration damping component A passes through communication position R1, communicates with the RF tag T of the vibration damping component A, thereby storing communication position passage information in the memory 55 of the RF tag T. The communication position passage information is information that can be used, for example, to estimate the frequency of use of railway vehicle B. Therefore, it becomes possible to estimate the degree of deterioration of the main body rubber part 120 more accurately.

[0048] Next, several specific examples of the tag housing section 130 of the vibration-damping component A will be described.

[0049] <First aspect of the tag storage section> First, a first embodiment of the tag housing section 130 will be described. Figure 4 shows the tag housing section 130A of the first embodiment. The tag housing section 130A is such that an RF tag T is embedded inside. The lower surface of the tag housing section 130A in Figure 4 is the surface that is fixed to the base material 110. The tag housing section 130A shown in Figure 4 covers the RF tag T from the outside without any gaps. In short, the tag housing section 130A is manufactured by covering the RF tag T with an uncrosslinked rubber material and then performing a vulcanization process to crosslink the uncrosslinked rubber material.

[0050] Figure 5 shows one aspect of the manufacturing process for vibration-damping component A having a tag housing portion 130A. As shown in Figure 5, vibration-damping component A having a tag housing portion 130A can be manufactured by a process S11 in which a main body rubber portion 120 is formed on a base material 110, and a process S12 in which a tag housing portion 130A is formed on the base material 110.

[0051] In step S11, an uncrosslinked rubber material for forming the main body rubber portion 120 is placed in the main body region 111 of the base material 110, and the uncrosslinked rubber material placed in the main body region 111 is crosslinked by vulcanization. This forms the main body rubber portion 120 while adhering it to the main body region 111.

[0052] In step S12, an uncrosslinked rubber material for forming the tag housing 130A is placed in the housing region 112 of the base material 110, and the uncrosslinked rubber material placed in the housing region 112 is crosslinked by vulcanization. This forms the tag housing 130A while adhering it to the housing region 112. In step S12, an uncrosslinked rubber material with the RF tag T covered is placed in the housing region 112. Therefore, the crosslinked tag housing 130A is formed with the RF tag T housed inside.

[0053] As described above, steps S11 and S12 are steps for forming the main rubber part 120 and the tag housing part 130A on the base material 110, respectively. Therefore, by performing steps S11 and S12, a vibration-damping component A can be manufactured, which has the main rubber part 120 and the tag housing part 130A containing the RF tag T provided on the base material 110.

[0054] Furthermore, steps S11 and S12 can be performed simultaneously. That is, the main body rubber portion 120 can be formed in the main body region 111 while the tag housing portion 130A can be formed in the housing region 112. This reduces the number of vulcanization steps in the manufacturing process of the vibration-damping component A. In other words, the vibration-damping component A can be manufactured in a short time.

[0055] Alternatively, one of the processes S11 or S12 may be performed first, and the other after the other. Specifically, for example, process S11 may be performed first, and then process S12 may be performed on the base material 110 in which the main rubber part 120 has been formed. In this case, the vulcanization temperature for process S11 and the vulcanization temperature for process S12 can be different. Specifically, for example, the vulcanization temperature for process S12 can be lower than the vulcanization temperature for process S11. In process S12, the rubber material coated with the RF tag T is vulcanized, so the RF tag T may be affected by the vulcanization temperature. The vulcanization temperature for a typical rubber material like that used in process S11 is around 150°C. In contrast, the vulcanization temperature for process S12 can be specifically set to around 50°C to 70°C. Furthermore, if the vulcanization temperature in process S12 is lower than that in process S11, the influence of the vulcanization temperature on the RF tag T can be reduced. Therefore, damage to the RF tag T during the manufacturing process of the vibration-damping component A can be suppressed. In addition, inexpensive RF tags with a low temperature tolerance can be used as RF tags T. This makes it possible to manufacture good quality vibration-damping components A at a low cost.

[0056] Furthermore, in step S12, it is preferable to use RF tags T that have been pre-coated with thermal insulation material. That is, when forming the tag housing 130A, it is preferable to cover the RF tags T with thermal insulation material, then cover the RF tags T, which are covered with thermal insulation material, with an uncrosslinked rubber material, and then crosslink the rubber material to form the tag housing 130A. In the vibration-damping component A manufactured in this way, thermal insulation material is provided between the RF tags T and the tag housing 130A. By pre-coating the RF tags T with thermal insulation material, the influence of the vulcanization temperature on the RF tags T can be reduced. Therefore, damage to the RF tags T can be suppressed even at high vulcanization temperatures. In addition, inexpensive RF tags with a low temperature tolerance can be used as RF tags T. As a result, good quality vibration-damping component A can be manufactured at low cost.

[0057] Furthermore, the vibration-damping component A having the tag housing portion 130A can also be manufactured by a different manufacturing process than that shown in Figure 5. Figure 6 shows another embodiment of the manufacturing process for the vibration-damping component A having the tag housing portion 130A, different from that shown in Figure 5. As shown in Figure 6, the vibration-damping component A having the tag housing portion 130A can be manufactured by a process S21 in which the main body rubber portion 120 is formed on the base material 110, a process S22 in which the tag housing portion 130A is formed, and a process S23 in which the tag housing portion 130A is bonded to the base material 110. Note that the process S21 shown in Figure 6 can be carried out in the same way as the process S11 described in Figure 5.

[0058] In step S22 of Figure 6, unlike step S12 described in Figure 5, where the tag housing 130A is formed directly on the base material 110, the tag housing 130A is formed separately from the base material 110. Specifically, in step S22, the RF tag T is covered with an uncrosslinked rubber material for forming the tag housing 130A, and the uncrosslinked rubber material covering the RF tag T is then crosslinked to form the tag housing 130A. In this way, the tag housing 130A containing the RF tag T is manufactured separately from the base material 110.

[0059] In step S23, following step S22, the tag housing portion 130A is bonded to the housing portion area 112 of the base material 110. That is, in step S23, the tag housing portion 130A is bonded to the base material 110, which already has the main rubber portion 120 attached to it, while separating it from the main rubber portion 120. For bonding the tag housing portion 130A to the base material 110, for example, an adhesive can be used. In the vibration-damping component A manufactured in this way, the tag housing portion 130A is bonded to the base material 110 by an adhesive.

[0060] By performing processes S21 and S22 separately, the vulcanization temperature in process S21 and the vulcanization temperature in process S22 can be set to different temperatures. Specifically, the vulcanization temperature in process S22 can be set to a lower temperature than that in process S21. Therefore, damage to the RF tag T during the manufacturing process of vibration-damping component A can be suppressed. In addition, inexpensive RF tags with a low temperature tolerance can be used as RF tags T. This allows for the inexpensive manufacture of good quality vibration-damping component A. Furthermore, in order to suppress the effect of heat on the RF tag T, RF tags T that have been pre-coated with insulating material may be used in process S22.

[0061] Note that the tag housing section 130A shown in Figure 4 is an example of a configuration in which the entire outer surface of the RF tag T is covered. However, the RF tag T only needs to be fixed to the tag housing section 130A, and a part of it may be exposed from the tag housing section 130A.

[0062] <Second aspect of the tag storage section> Next, a second embodiment of the tag housing section 130 will be described. Figure 7 shows the tag housing section 130B of the second embodiment. The tag housing section 130B has a housing space 131 for housing RF tags T and an opening 132 connected to the housing space 131. The lower surface of the tag housing section 130B in Figure 7 is the surface that is fixed to the base material 110. In other words, the opening 132 of the tag housing section 130B is provided on the opposite side from the surface that is fixed to the base material 110. In short, the tag housing section 130B is formed with the housing space 131 and the opening 132 provided, and then the RF tags T can be housed inside the housing space 131 from the opening 132.

[0063] Figure 8 shows the manufacturing process for vibration-damping component A having a tag housing section 130B. As shown in Figure 8, vibration-damping component A having a tag housing section 130B can be manufactured by the following steps: step S31, forming the main body rubber section 120 on the base material 110; step S32, forming the tag housing section 130B on the base material 110; and step S33, housing the RF tag T in the tag housing section 130B. Note that step S31 shown in Figure 8 can be carried out in the same way as step S11 described in Figure 5.

[0064] In step S32, an uncrosslinked rubber material for forming the tag housing 130B is placed in the housing region 112 of the base material 110, and the uncrosslinked rubber material placed in the housing region 112 is crosslinked by vulcanization. This forms the tag housing 130B while adhering it to the housing region 112. In step S32, a housing space 131 and an opening 132 are provided in the formed tag housing 130B. Although the housing space 131 has an undercut shape, in this embodiment, since rubber is used for the tag housing 130B, the tag housing 130B can be easily separated from the mold.

[0065] In step S33, following step S32, the RF tag T is housed in the housing space 131 of the tag housing section 130 by passing it through the opening 132. Here, in the example tag housing section 130B shown in Figure 7, the size of the opening 132 is narrower than the size of the RF tag T. In other words, in step S32, the opening 132 of the tag housing section 130B is formed to be narrower than the size of the RF tag T. However, in this embodiment, the material of the tag housing section 130B is rubber. Therefore, as shown in Figures 9(a) to 9(b), the RF tag T can be housed in the housing space 131 of the tag housing section 130B while widening the opening 132. Thus, a vibration-damping component A having a tag housing section 130B can be manufactured by the process shown in Figure 8.

[0066] Thus, in the vibration-damping component A having a tag housing section 130B, the RF tag T can be housed in the tag housing section 130B after the tag housing section 130B has been formed. Therefore, it is possible to avoid the RF tag T being affected by the vulcanization temperature when the tag housing section 130B is vulcanized. In addition, inexpensive RF tags with a low temperature tolerance can be used as RF tags T. Furthermore, there is no need for insulating materials to prevent the RF tags T from being affected by heat. In addition, the RF tags T will not be damaged by the pressure of the rubber material injected into the mold cavity of the tag housing section 130B. As a result, good quality vibration-damping component A can be manufactured at low cost. It should be noted that even in the vibration-damping component A having a tag housing section 130B, RF tags T that have been pre-coated with insulating material may be used. This makes it possible to suppress damage to the RF tags T due to temperature effects, even when the vibration-damping component A is used in a high-temperature environment.

[0067] Furthermore, the opening 132 of the tag storage section 130B is narrower than the size of the RF tag T. Therefore, it is possible to prevent the RF tag T stored in the tag storage section 130B from falling out of the storage space 131 through the opening 132. It is also possible to make the storage space 131 narrower than the RF tag T. This prevents the RF tag T stored in the storage space 131 from moving around within the storage space 131.

[0068] Furthermore, the opening 132 of the tag storage section 130B may be closed with a cover member 135 after the RF tag T is stored in the storage space 131, as shown in Figure 9(c). This further prevents the RF tag T stored in the tag storage section 130B from falling out. It also prevents rainwater and other liquids from entering the tag storage section 130B. For the cover member 135, for example, an adhesive or sealant can be used. That is, by applying an adhesive or sealant so that the opening 132 is closed and allowing it to harden, it can function as a cover member 135. Alternatively, for example, adhesive tape can be used for the cover member 135.

[0069] Furthermore, it is preferable to perform steps S31 and S32 simultaneously. That is, the main body rubber portion 120 can be formed in the main body region 111 while the tag housing portion 130B can be formed in the housing region 112. This reduces the number of vulcanization steps in the manufacturing process of the vibration-damping component A. In other words, the vibration-damping component A can be manufactured in a short time.

[0070] Furthermore, it is also possible to manufacture the vibration-damping component A having the tag housing 130B by performing either process S31 or process S32 first and the other process after the other. Alternatively, for example, the tag housing 130B can be formed separately from the base material 110, and the formed tag housing 130B can be bonded to the housing area 112 of the base material 110 to manufacture the vibration-damping component A having the tag housing 130B. In this case, the RF tag T can be housed in the housing space 131 of the tag housing 130 after the tag housing 130B has been bonded to the base material 110. Alternatively, for example, the RF tag T can be housed in the housing space 131 of the tag housing 130, and then the tag housing 130B can be bonded to the base material 110.

[0071] <Third aspect of the tag storage section> Next, a third embodiment of the tag storage section 130 will be described. Figure 10 shows the tag storage section 130C of the third embodiment. Similar to the tag storage section 130B of the second embodiment, the tag storage section 130C also has a storage space 131 for accommodating RF tags T and an opening 132 connected to the storage space 131. The lower surface of the tag storage section 130C in Figure 10 is the surface that is fixed to the base material 110. In other words, the opening 132 of the tag storage section 130C is provided on the side. And, similar to the tag storage section 130B of the second embodiment, the tag storage section 130C is also formed with the storage space 131 and opening 132 provided, and then the RF tags T can be accommodated into the storage space 131 from the opening 132. The tag storage section 130C of the third embodiment differs from the tag storage section 130B of the second embodiment in that the size of the opening 132 is not narrower than the size of the RF tags T.

[0072] The tag housing section 130C can also be manufactured using basically the same procedure as the tag housing section 130B of the second embodiment. As shown in Figures 11(a) to 11(b), the RF tag T can be housed inside the tag housing section 130C by passing it through the opening 132 of the tag housing section 130C. As shown in Figure 11, in the tag housing section 130C of the third embodiment, the direction of movement of the RF tag T when inserted into the housing space 131 is different from that of the tag housing section 130B of the second embodiment shown in Figure 9. In the case of the tag housing section 130C, since the opening 132 is not narrower than the RF tag T, it is preferable to close the opening 132 with the lid member 135 after housing the RF tag T, as shown in Figure 11(C).

[0073] As described in detail above, the vibration-damping component A according to the above embodiment is for railway vehicles and comprises a base material 110, a main rubber part 120, an RF tag T, and a tag housing part 130. The main rubber part 120 is provided on the base material 110 and functions as a cushioning material in the railway vehicle B. The RF tag T has a memory 55 which contains a management information storage area 56, a status information storage area 57, and a communication location passage information storage area 58. The management information, status information, and communication location passage information stored in this memory 55 are all information related to the main rubber part 120. The tag housing part 130 is made of rubber and houses the RF tag T inside. The tag housing part 130 is provided on the base material 110, away from the main rubber part 120. Therefore, it is possible to appropriately obtain information from the RF tag T. Accordingly, the above embodiment enables more appropriate management of the vibration-damping component A having a main rubber part 120.

[0074] The embodiments described above are merely illustrative and do not limit the disclosed technology in any way. Therefore, the disclosed technology can naturally be improved and modified in various ways without departing from its essence.

[0075] In other words, the disclosed technology is applicable not only to vibration-damping component A shown in Figure 1, but also to vibration-damping components for other railway vehicles. Specifically, for example, the disclosed technology may be applied to vibration-damping component A5 shown in Figure 12. Vibration-damping component A5 is a cylindrical component having a first base material 510 and a second base material 511, with a main rubber portion 520 between them. Figure 12 shows an example in which a tag housing portion 530 containing an RF tag T is provided near the radial outer end of the second base material 511. Even with such a vibration-damping component A5, the same effect as vibration-damping component A shown in Figure 1 can be obtained.

[0076] Figure 13 shows a vibration-damping component A6 having a first base material 610, which is a shaft member, and three cylindrical base materials 611, 3, and 4. The third and 4 base materials 612 and 4 are positioned between the first base material 610 and the second base material 611, which is located on the outermost periphery. The vibration-damping component A6 has a main rubber portion 620 between adjacent base materials in the radial direction. Figure 14 shows a vibration-damping component A7 having a main rubber portion 720 between the first base material 710, which is a shaft member, and the second and third base materials 711 and 3, which are positioned opposite each other so as to sandwich the first base material 710. Figure 15 shows a vibration-damping component A8 having a main rubber portion 820 between the first base material 810, which is a shaft member, and the cylindrical second base material 811. The present disclosed technology can also be applied to vibration-damping components as shown in Figures 13 to 15. In the vibration-damping components shown in Figures 13 to 15, the choice of which of the multiple base materials to use for the tag housing can be determined as appropriate.

[0077] In the above embodiments, the tag storage section was described as being made of rubber. However, resin can be used as the material for the tag storage section. For example, the tag storage section 130A shown in Figure 4, described as the first embodiment, and the tag storage section 130C shown in Figure 10, described as the third embodiment, can be applied without any problems even if they are made of resin. Also, when the tag storage section is made of resin, the procedure for the uncrosslinked rubber material and the procedure for crosslinking the uncrosslinked rubber material described in the above embodiments can be replaced with the procedure for the liquid resin material and the procedure for curing the liquid resin material, respectively, as appropriate. Furthermore, for example, the base material is not limited to metal, but can also be made of resin. However, a metal base material is preferable to a resin base material in terms of strength, rigidity, dimensional accuracy, etc.

[0078] In the above embodiment, a method was described in which the tag storage portion is formed separately from the base material, and then the formed tag storage portion is fixed to the base material by adhesive. However, the method of fixing the tag storage portion to the base material is not limited to adhesive, and other methods such as fitting, press-fitting, or screws can also be used. The same applies to the method of fixing the lid member that closes the opening in a tag storage portion that has an opening.

[0079] Furthermore, in the above embodiment in which the RF tag antenna and reader device perform wireless communication using radio waves or electromagnetic waves, a situation may arise in which communication cannot be performed properly if the RF tag is in contact with a conductive material. Specifically, for example, if the surface of the base material of the vibration-damping component is conductive, communication with the reader device may be hindered if the RF tag comes into contact with the base material. Therefore, if the RF tag may come into contact with a conductive base material, for example, a metal-compatible tag that can communicate properly even when in contact with a conductive material may be used as the RF tag. Alternatively, for example, if an RF tag that is not a metal-compatible tag is used, insulation treatment may be applied to ensure that the RF tag and the base material are reliably insulated. For example, when using the tag housing section 130A in Figure 4, an insulating rubber material may be used. Alternatively, for example, it may be considered to apply insulation treatment to at least the surface of the RF tag located on the base material side in advance. As an insulation treatment, for example, an insulating layer may be provided using an insulating adhesive, paint, cation, plating, adhesive tape, etc. The insulating layer may, of course, be provided on the entire outer surface of the RF tag. The insulating layer may be provided on the surface of the substrate that can come into contact with the RF tag, i.e., in the housing area of ​​the substrate. Alternatively, for example, the insulating layer may be provided on both the RF tag and the substrate. By providing an insulating layer on at least one of the RF tag and the substrate, communication interference with the reader device can be prevented while reducing costs compared to using metal-compatible tags. Furthermore, by using an insulating resin substrate, communication interference with the reader device caused by the RF tag coming into contact with the substrate can also be prevented while reducing costs compared to using metal-compatible tags.

[0080] Furthermore, the above embodiments described an example in which the disclosed technology is applied to vibration-damping components for railway vehicles. However, the disclosed technology can also be similarly applied to vibration-damping components for construction machinery. Furthermore, the above embodiments described an example of a management system in which the reader device is fixed as a communication position along the route on which the railway vehicle travels. However, for example, a management system may be provided in which a worker performing inspection work on railway vehicles can move around with the reader device in their hand to communicate with RF tags on multiple railway vehicles equipped with vibration-damping components and obtain information from the RF tags. Also, for example, a management system may include a reader device that is fixed as a communication position along the route on which the railway vehicle travels, and a reader device that can be used while moving the communication position.

[0081] Furthermore, the above embodiment described a configuration in which management information, status information, and communication location information are all stored in the RF tag's memory. However, it is sufficient for the RF tag's memory to store at least one of the management information, status information, and communication location information. Also, for example, in a configuration where status information is not stored, a passive type of RF tag can be used. In other words, the hardware configuration and the database configuration for storing each piece of information described in the above embodiment are merely examples, and any configuration that can realize each function is acceptable.

[0082] Furthermore, the number of RF tags, the number of vibration-damping components, and the number of users in the vibration-damping component management system are merely examples; for example, a management system that manages even more vibration-damping components can be configured. Also, in the above embodiment, a management system with one reader device, one user computer, and one administrator computer was described. However, these numbers are also merely examples; for example, a management system with even more computers can be configured.
