Description

Technical Field

[0001] This invention relates to a liner for winding an unvulcanized rubber material.

Background Art

[0002] A liner winds a long unvulcanized rubber material formed by an extruder or calender roll. After the wound unvulcanized rubber material is paid out and separated in the next process, it is used again for winding the unvulcanized rubber material. Then, it is repeatedly used many times and discarded when it becomes dirty and unusable.

[0003] Whether a liner can be used or not is determined by visual inspection by a person. For this reason, the judgment criteria are not uniform, and a dirty one that is not suitable for use may be used. Moreover, it is difficult to use all the liners held in an orderly and equal manner, and it is also difficult to properly manage all the liners held. For this reason, it may not be noticed that the number of usable liners is decreasing, or conversely, the liners may be left unused. On the other hand, for liners, especially fiber liner cloths as disclosed in Japanese Patent No. 3924277, it takes time from production to delivery. For this reason, there are cases where the required number of liners cannot be prepared when needed.

[0004] When trying to efficiently manage articles, generally RFID (Radio Frequency Identification) is used, but RFID management of liners has not been performed so far.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The main problem of this invention is to appropriately manage liners by paying attention to the number of uses.

Means for Solving the Problems

[0006] Therefore, the present invention provides the following system.

[0007] That is, the usage management system for the unvulcanized rubber material winding liner includes an information storage medium held by a liner that winds up the unvulcanized rubber material, a reader that non - contact reads the information written in the information storage medium, and a server that receives the information read by the reader via a user terminal on the user side that uses the liner. The storage unit of the server includes a usage information storage unit for each liner. And the control unit of the server counts the number of times of use of the liner having the information storage medium based on the information input by reading the information storage medium of the liner in the use of the liner, and updates the usage times information when it is less than the planned number of times of use. On the other hand, when the planned number of times of use is exceeded, an error signal is transmitted to the user terminal, which is a configuration for performing such control.

[0008] In this configuration, the number of times of use is counted by the server based on the reading of the information storage medium by the reader in the use of the liner, that is, based on the information of the information storage medium of the liner read by the user side from before the start of use to after the end of use. The number of times of use is compared with the planned number of times of use, which is the planned number of times of use, and is used for the server's control unit to determine whether it can be used, and is updated in the usage information storage unit of the storage unit. The information in the storage unit of the server can be confirmed from the user terminal and is used as necessary for inventory management and the like.

Effect of the Invention

[0009] According to the present invention, since the number of times of use of the liner can be counted and the determination of whether the liner can be used is made based on a preset number of times of use, a uniform determination without variation is possible. By appropriately setting the planned number of times of use, it is possible to prevent a soiled liner from being used unexpectedly. Moreover, since the necessary liner can be searched by the reader, the owned liners can be used appropriately without waste. In addition, since it is managed based on the number of times of use, it is possible to grasp the remaining number of times of use. For this reason, it is also possible to place an order for a liner to replace a liner that will become unusable in the near future, or to develop a good liner by collecting information related to the usage mode.

Embodiments for Carrying Out the Invention

[0011] One embodiment for carrying out the present invention will be described below with reference to the drawings.

[0012] A preferred example of a usage management system for an unvulcanized rubber material winding liner 11 (hereinafter referred to as "liner") (hereinafter referred to as "system") is configured using a manufacturer terminal 13, a server 14, and a user terminal 15 that are connected to each other via a network 12, as shown in FIG. 1. The network 12 is composed of the Internet, an intranet, etc., and the manufacturer terminal 13 and the user terminal 15 are composed of information processing devices such as personal computers and tablet terminals. The server 14 may be a general-purpose computer such as a workstation or a personal computer, or may be realized by cloud computing. In addition to these, a liner 11, an information storage medium held by the liner, a reader or a reader / writer 16 that reads information from the information storage medium in a non-contact manner, and a printer for the storage medium (not shown) that prints or writes to the information storage medium are provided. As the information storage medium, an RF tag 17 of RFID that can read and write data in a non-contact manner using radio waves is used (see FIG. 3).

[0013] In FIG. 1, the manufacturer terminal 13 is used by the manufacturer, that is, the person who manufactures the liner, and the user terminal 15 is used by the user, that is, the person who uses the liner 11 delivered from the manufacturer. The server 14 is a device that processes and stores the data received from the user terminal 15 and transmits the data to each terminal, and is configured to be able to access the necessary information from each terminal.

[0014] In this system, the number of times the liner 11 is used is counted, and the usage times information is used for management.

[0015] Here, the liner 11 will be briefly described.

[0016] The liner 11 is formed in a flexible sheet shape and is generally in a long strip shape. Usually, it is wound in a roll as shown in FIG. 2. In use, as shown in the upper part of FIG. 2, while feeding out the liner 11 in a wound state, the unvulcanized rubber material 18 is extruded and stacked thereon, and as shown in the lower part of FIG. 2, it is wound in a state sandwiching the unvulcanized rubber material 18. Then, the unvulcanized rubber material 18 together with the liner 11 is moved to the next process and the unvulcanized rubber material 18 is separated. That is, the unvulcanized rubber material 18 is separated while feeding out the liner 11. The liner 11 from which the unvulcanized rubber material 18 has separated is wound in a roll. Such use is repeated.

[0017] That is, the use of the liner 11 starts from the stage of being set in a winding machine for winding the unvulcanized rubber material 18 by stacking the unvulcanized rubber material 18 (start of use). Then, after passing through the state of winding the unvulcanized rubber material 18, the unvulcanized rubber material 18 is separated and the liner 11 is set in a winding machine for winding, and after the winding is completed, it ends (end of use).

[0018] Therefore, in order to count the number of times the liner 11 is used, not only while the unvulcanized rubber material 18 is being held, but also during the time from before the start of the winding operation of the unvulcanized rubber material 18 to after the separation of the unvulcanized rubber material 18 is completed and the winding is finished, if at least one count is performed at any timing, the use can be surely counted.

[0019] In FIG. 1, the wound liners 11 drawn on the right side are divided into two types, that is, those with the winding shaft laid horizontally and those with the winding shaft set vertically. In the figure, the former liner 11 drawn in the upper part shows the one in use, and the latter liner 11 drawn in the lower part shows the one in non - use such as during storage.

[0020] Fig. 3 shows a perspective view of the liner 11. The liner 11 is provided with RF tags 17 at the four corners, that is, at both ends in the width direction at both ends in the longitudinal direction. This is because these positions do not interfere with the unvulcanized rubber material 18 when the unvulcanized rubber material 18 is wound. Also, this is to ensure the reading accuracy regardless of which end in the longitudinal direction becomes the winding end side.

[0021] As the RF tag 17, a passive type that does not require battery replacement may be used, but other types can also be used. The RF tag 17 can be fixed to the liner 11 by appropriate means such as pasting or sewing.

[0022] The memory of the RF tag 17 stores code information for identifying the RF tag 17. The code information of the four RF tags 17 attached to one liner 11 may be different or the same. Even if they are different, the liner 11 to which the RF tag 17 is attached can be accurately identified by linking with the liner ID which is the identification information of the liner 11.

[0023] The user terminal 15 is composed of a personal computer or the like in which software and a database are installed and which cooperates with the aforementioned reader / writer 16. As shown in Fig. 4, it has a communication unit 51, a storage unit 52, a display unit 53, an input unit 54, and a control unit 55. The communication unit 51 is a communication interface for receiving signals from the reader / writer 16 and communicating with the server 14 or the like via the network 12. The storage unit 52 stores programs necessary for control operations such as programs for instructing the reader / writer 16, as well as necessary information. The display unit 53 displays text, images, etc. according to the control operations by the control unit 55. The input unit 54 is a part where the user inputs instructions to the control unit 55. The control unit 55 is configured to perform drive control of each unit according to the programs stored in the storage unit 52.

[0024] Such a user terminal 15 may be configured as a handy terminal integrated with the reader / writer 16.

[0025] Although not shown, the manufacturer terminal 13 is configured by a personal computer or the like with software and a database installed, similar to the user terminal 15. A program necessary for issuing an RF tag by the RFID printer as the printer for the storage medium described above is stored in its storage unit. Since it can be configured using a general-purpose computer similar to the user terminal, detailed description thereof is omitted.

[0026] As shown in FIG. 5, the server 14 includes a communication unit 41, a storage unit 42, and a control unit 43. The communication unit 41 is a communication interface for communicating with a user terminal or the like via a network. The storage unit 42 stores programs and necessary data required for control operations. As a part for storing necessary data, it has a user information storage unit 44 and an order receiving information storage unit 45.

[0027] As shown in FIG. 6, the user information storage unit 44 in the storage unit 42 includes a user ID which is identification information of the user, user basic information 46 such as the name and address of the user, and in addition, a use information storage unit 47 for each liner 11, an inventory information storage unit 48, and a disposal information storage unit 49. The user ID and the user basic information 46 are input via the manufacturer terminal 13 in association with the code information of the RF tag 17 before the delivery of the liner 11.

[0028] The use information storage unit 47 is a part that stores information related to the use status of the liner 11 that the user owns or has owned in a readable and writable manner, and is provided corresponding to the identification information (liner ID) of the liner 11 with the RF tag 17 attached. The liner ID is written in advance by the manufacturer side before the delivery of the liner 11, but can also be rewritten by the user side. The liner ID is stored in association with the code information of the RF tag 17 fixed to the liner 11.

[0029] The information stored in the usage information storage unit 47 includes usage times information 47a, planned usage times information 47b, usage end information 47c, remaining usage times information 47d, liner state information 47e, usage target information 47f, and liner type information 47g.

[0030] The usage times information 47a indicates the usage times of the liner 11. It is input by reading the RF tag 17 of the liner 11, and the usage times are counted each time it is used. In this example, the counting in the use of the liner 11 is set as the counting before the winding operation of the unvulcanized rubber material 18. That is, the reading of the RF tag 17 of the liner 11 in the use of the liner 11 is performed before the winding operation of the unvulcanized rubber material 18 and counted as the usage times. The usage times information 47a is stored together with the date and time information indicating the date and time of the reading.

[0031] The planned usage times information 47b is appropriately set in advance to indicate the usage limit of the liner 11, and the usage times before the liner 11 gets severely dirty are stored according to the type of the liner 11. The planned usage times information 47b is input and stored from the manufacturer terminal 13 before the delivery of the liner 11. It may also be stored by input from the user terminal 15.

[0032] It is also possible to omit the storage of such planned usage times information 47b and count the planned usage times by counting down the usage times corresponding to the planned usage times in the counting of the usage times.

[0033] The usage end information 47c is information indicating that the unvulcanized rubber material 18 being wound has been separated. After the separation operation of the wound unvulcanized rubber material 18, it is input and stored together with the date and time information indicating the date and time of reading by reading the RF tag 17. Since the usage count information 47a is updated by counting before the winding operation of the unvulcanized rubber material 18 as described above, the usage end information 47c is beneficial in that the current state of the liner 11 can be grasped by comparing it. That is, if the usage end count indicated by the usage end information 47c is the same as the usage count, it can be known that the liner 11 is in a non-use state and does not hold the unvulcanized rubber material 18 at present. When the usage end count is one less than the usage count, it can be known that the liner 11 is in a use state and holds the unvulcanized rubber material 18 at present. Also, by comparing the reading date and time of the usage count information 47a and the reading date and time of the usage end information 47c, the time during which the liner 11 held the vulcanized rubber material, in other words, the length of time during which the liner 11 and the unvulcanized rubber material 18 were in contact with each other can be known.

[0034] The remaining usage count information 47d is information obtained by subtracting the usage count from the planned usage count, and indicates how many more times the liner 11 can be used. It is counted down each time the usage count is counted.

[0035] The liner state information 47e is an item input from the user terminal 15 by the user who uses the liner 11 regarding the state of the liner 11. Such items include those indicating the degree of dirt step by step, those indicating the type of dirt, those indicating the presence or absence and degree of fraying, scratches, wrinkles, etc. step by step.

[0036] The usage target information 47f is an item input from the user terminal 15 by the user who uses the liner 11 regarding the unvulcanized rubber material 18 wound on the liner 11.

[0037] The liner type information 47g is what the user who uses the liner 11 inputs from the user terminal 15 regarding basic information such as the material and size of the liner 11. It may also be input and stored from the manufacturer terminal 13 together with the product number and manufacturing number of the liner 11, etc.

[0038] In this way, the usage information storage unit 47 stores, for each liner 11, the liner 11 owned by each user and various information related to its use.

[0039] In the inventory information storage unit 48, those liner IDs stored in the usage information storage unit 47 that do not match the liner IDs stored in the disposal information storage unit are stored as inventory information.

[0040] The disposal information storage unit 49 stores the liner IDs of the liners 11 discarded by each user as disposal information. The disposal information is stored together with the input date, disposal date, etc.

[0041] The order receiving information storage unit 45 in the storage unit 42 stores the order information of the liner 11 input from the user terminal 15. The order information is composed of the input date and time, order date, product number of the liner, quantity, desired delivery date, etc.

[0042] The control unit 43 performs drive control of each unit according to the program stored in the storage unit 42. As shown in FIG. 5, there are a usage information management unit 43a, an inventory information management unit 43b, a disposal information management unit 43c, and an order receiving information management unit 43d.

[0043] The usage information management unit 43a reads and writes usage information related to the use of each liner 11 of each user based on the read information of the RF tag 17 input from the user terminal 15, updates the data, and performs calculation processes such as comparison operations and logical operations. For example, when the usage count is incremented, the remaining usage count information is decremented. At this time, when the usage count of the liner is less than or equal to the planned usage count, the usage count information is updated, while when it exceeds the planned usage count, an error signal is sent to the user terminal 15. Also, necessary judgments are made by comparing the updated usage count and the remaining usage count. If usage end information, liner usage status information, usage target information, and liner type information are input from the user terminal, the information is stored corresponding to the liner ID.

[0044] The inventory information management unit 43b reads the liner IDs of the usage information storage unit 47 and the disposal information storage unit 49, performs a comparison operation, and stores the result in the inventory information storage unit 48. That is, the liner IDs stored in the usage information storage unit 47 that are not the liner IDs stored in the disposal information storage unit 49 are used as inventory information.

[0045] When the liner ID of the liner 11 discarded by each user is input from the user terminal 15, the disposal information management unit 43c stores the liner ID in the disposal information storage unit 49.

[0046] The order information management unit 43d stores the order details related to the liner 11 input by each user from the user terminal 15.

[0047] The system composed of the above units mainly performs the processes as shown in the sequence diagram of FIG. 7 to realize the proper use of the liner 11 without waste and obtain other conveniences.

[0048] That is, when a user who purchases and uses the liner 11 with the RF tag 17 from the manufacturer reads the RF tag 17 and transmits necessary information to the server 14 (step S11), the server 14 having a database updates the data, performs necessary calculation processing, and transmits the necessary information to at least one of the user terminal 15 and the manufacturer terminal 13 (step S12). Then, the information is displayed on each terminal (steps S13, S14), prompting judgment and operations.

[0049] The processing such as data update performed by the server (step S12) is roughly divided into three types. One is "usage count management" to prevent the use of a dirty liner 11, the second is "liner quantity management" to secure available liners 11, and the third is "information collection" to enable the provision and operation of better liners 11 based on the usage status of the liner 11.

[0050] These processing operations are performed as follows. All of them are processed in the flow shown in the sequence diagram of FIG. 7.

[0051] The usage count management, which is the first processing operation, is triggered by the user's reading of the RF tag 17. That is, before the use of the liner 11, here the winding operation of the unvulcanized rubber material 18, the RF tag 17 of the liner 11 used for winding is read using the reader / writer 16 or the handy terminal. Then, the control unit 55 of the user terminal 15 inputs the code information of the RF tag 17 as information necessary for counting the usage times and transmits it to the server 14. The usage information management unit 43a in the control unit 43 of the server 14 compares the usage times of the usage times information 47a with the planned usage times of the planned usage times information 47b when the code information is input, and determines whether the planned usage times are exceeded by counting up. If not exceeded, the usage times information 47a is updated. At the same time, the remaining usage times information 47d is also updated. On the other hand, if exceeded, a notification indicating that the planned usage times have been reached is sent to the user terminal 15. The notification is displayed so as to be visible or audible. The manufacturer terminal 3 may also be notified.

[0052] The user who has received the indication uses another liner 11 that has not reached the planned number of uses. Further, the user evaluates the state of the liner 11 that has reached the planned number of uses, and inputs information regarding the state of the liner from the user terminal 15. The liner state information 47e input from the user terminal 15 is stored in the use information storage unit 47 for each liner ID as the liner state information 47e by the use information management unit 43a in the control unit 43 of the server 14.

[0053] Note that the liner state information 47e obtained by such evaluation of the liner 11 may be stored at an appropriate stage such as before use of the liner 11 or during inventory taking.

[0054] The user reads the RF tag 17 even after the separation operation of the wound unvulcanized rubber material 18. When the RF tag 17 of the liner 11 used for winding is read, the control unit 55 of the user terminal 15 inputs the code information of the RF tag 17 and transmits it to the server 14. The use information management unit 43a in the control unit 43 of the server 14 stores the input code information in the use information storage unit 47 as the use completion information 47c. Also in this case, the user may evaluate the state of the used liner 11 and input the liner state information 47e from the user terminal 15.

[0055] The liner number management, which is the second processing operation, is performed when the use information management unit 43a in the control unit 43 of the server 14 determines that the remaining number of uses of the liner 11 has decreased, and when the disposal information of the liner 11 is input from the user terminal 15.

[0056] The determination of whether the remaining number of uses of the liner 11 is small or not is made when the data is updated in the above-described usage count management, and is determined based on whether the number of uses stored in the usage information storage unit 47 related to the liner 11 that is the target of data update has approached the planned number of uses by a predetermined amount or more. That is, when the usage count information 47a and the remaining usage count information 47d are updated by counting the number of uses, the usage information management unit 43a in the control unit 43 of the server 14 compares the remaining number of uses with the planned number of uses, and determines, for example, whether the number of uses has reached 80% of the planned number of uses. The criterion for determining whether the remaining number of uses is small is set in advance in consideration of factors such as the time required for manufacturing the liner 11 and the inventory quantity.

[0057] Only when the control unit 43 of the server 14 determines that the remaining number of uses of the liner 11 is small, the control unit 43 transmits the information of that liner 11 to the manufacturer terminal 13 and the user terminal 15 for notification, and causes it to be displayed on each terminal together with the remaining number of uses. The notification may be made only to the manufacturer terminal 13. Conversely, when it is not necessary for the manufacturer to forecast orders and formulate production plans, the notification may be made only to the user terminal 15.

[0058] Upon receiving the display, the manufacturer determines whether there is likely to be an order for the liner 11, and if necessary, issues a manufacturing instruction for the liner 11 in consideration of the delivery date. On the other hand, upon receiving the notification, the user accesses the storage unit 42 of the server 14, checks the number of liners 11 owned (inventory) and the remaining number of uses of those liners 11, and determines whether to place an order for a new liner 11.

[0059] The waste information of the liner 11 is input from the user terminal 15 when the user discards the liner 11. Even if the liner 11 has reached the planned number of uses or the liner 11 still has remaining uses but is severely soiled, it will be discarded.

[0060] When the liner ID of the liner 11 to be discarded is input to the user terminal 15, it is transmitted to the server 14, and the discarded information management unit 43c in the control unit 43 causes the discarded information storage unit 49 to store the liner ID as discarded information. Also in this case, the user may evaluate the state of the liner 11 to be discarded and input the liner state information 47e from the user terminal 15. Further, when the user inputs the discarded information, the user accesses the storage unit 42 of the server 14, checks the number of liners 11 owned (inventory) and the remaining number of uses of those liners 11, and determines whether to order new liners 11.

[0061] The information collection, which is the third processing operation, is performed according to a program predetermined by the control unit 43 of the server 14 based on the read information and input information from the user terminal 15 as described above. That is, when the code information of the RF tag 17 is read, it is stored in the storage unit as the usage times information 47a, the usage end information 47c, etc., and when the liner state information 47e, the discarded information, etc. are input, they are also updated. And the necessary information stored can be freely accessed from either the manufacturer terminal 13 or the user terminal 15. For example, necessary information such as how many of the owned liners 11 are currently in use, how many liners 11 have a small remaining number of uses, and whether there are enough liners 11 required for the next scheduled production can be obtained. These information are effective for establishing a production system without waste for the user. In addition, information regarding the liner 11 as a product can also be obtained, such as the relationship between the number of uses and the lifespan, the difference in the deterioration of the liner 11 due to the length of time from when the unvulcanized rubber material 18 is wound up to when it is separated, and the tendency of damage to the liner 11. These information are beneficial for producing better liners 11.

[0062] According to the above system, the number of times the liner 11 is used is counted based on the reading of the RF tag 17 during the use of the liner 11, that is, based on the liner 11 read by the user from before the start of use to after the end of use, and the server 14 determines whether use is permitted based on the number of times of use. Therefore, a uniform judgment without variation is possible. If the planned number of times of use is set appropriately, it is possible to prevent the dirty liner 11 from being used unexpectedly. Moreover, since the RF tag 17 is read during the use of the liner 11, the number of times of use can be accurately counted.

[0063] Since a plurality of RF tags 17 to be read are provided on the liner 11, reading can be performed even if some of the RF tags 17 are missing. However, since the RF tags 17 are fixed at the four corners so as not to interfere with the unvulcanized rubber material 18, they are unlikely to fall off.

[0064] The RF tags 17 fixed at the four corners of the long strip-shaped liner enable highly accurate reading regardless of which side in the longitudinal direction is the winding end side. That is, accurate reading can be performed regardless of the difference in the winding state of the liner.

[0065] Since the reading of the RF tag 17 for counting the number of times of use is configured to be performed before the winding operation of the unvulcanized rubber material 18 and after the separation operation, it is possible to clearly grasp what state the liner 11 is in at present, that is, whether it is in the state of having wound the unvulcanized rubber material 18 or not. Moreover, since the RF tag 17 has a search function, the liner 11 can be reliably managed.

[0066] The control unit 43 of the server 14 is configured to notify the user terminal 15 and the manufacturer terminal 13 to that effect when the remaining number of times of use of one liner 11 approaches the planned number of times of use. Therefore, it can contribute to preventing the occurrence of a shortage of liners that the user of the liner 11 does not expect. Also, for the manufacturer of the liner 11, it is possible to enable planned production.

[0067] Furthermore, since the information accumulated through the use of the liner 11 can be accessed from both the user terminal 15 and the manufacturer terminal 13, by making use of the information respectively, it is possible to effectively carry out production by using the liner 11 efficiently without waste, and to contribute to the development of a better liner 11. Through the continuous operation of the system, it is also possible to find the planned number of uses suitable for the liner 11.

[0068] The above configuration is one form for implementing the present invention, and the present invention is not limited only to the foregoing configuration, and other configurations can be adopted.

[0069] For example, even for a liner that has reached the planned number of uses, if it can be used without excessive dirt, the control unit may be configured so that it can be used beyond the planned number of uses.

[0070] Also, the fixed position of the RF tag 17 may be a part other than the four corners of the liner 11, and the number of attachments may also be other than four.

[0071] The attachment of the RF tag 17 and the writing of necessary information to the RF tag 17 may be performed by the user side.
