Description

Technical Field

[0001] The present invention relates to a tire provided with a temporary identification label (i.e., an identification label that is only used during tire handling and is removed when the tire is mounted on the corresponding rim).

[0002] The present invention finds advantageous applications in the handling of so-called TBR ("Truck and Bus Radial") tires, that is, large-sized tires, and is explicitly referred to in the following description without loss of generality.

Background Art

[0003] Generally speaking, when it is necessary to handle tires at the end of a production line (typically for loading tires into cargo containers) or in a warehouse, when a bundle of tires is placed on a pallet, an operator uses a forklift provided with a pair of forks that lift (at least) the bundle of tires from below, or a forklift provided with clamps that clamp the bundle of tires laterally.

[0004] In recent years, so-called "smart" tires have been developed that are provided with RFID devices, where RFID stands for "Radio Frequency Identification", typically a transponder. RFID devices enable remote communication of items of information such as the identification, characteristics and history of a tire.

[0005] As a result, operators are required to not only move tires using a forklift, but also access this information and read the RFID device associated with the tire through a suitable reader. This is, for example, to confirm that the RFID device operates correctly on the correct tire, and / or to store possible changes in the position of the tire in an electronic register.

[0006] Forklift operators typically carry manual readers (i.e., lightweight readers that are easy to carry). After loading tires onto the forklift, the operator dismounts, approaches the tires with the reader, and reads the corresponding RFID device to identify the tires in a specific way. However, this mode of operation is inefficient and wastes a great deal of time because the operator must dismount (and therefore stop the forklift and place it in a safe parking position). Furthermore, the operator must place the manual reader near each individual tire to read the corresponding RFID device (i.e., known manual readers cannot read the RFID devices of all tires in a bundle simultaneously, requiring the reader to be placed near each tire in the bundle).

[0007] In this regard, it should be noted that the maximum reading distance of an RFID device embedded in a single tire is often approximately 1-2 meters, and a stack of tires typically exceeds 3 meters in height (and therefore exceeds the maximum reading distance). Furthermore, when several tires are close together (stacked together), shielding and / or reflection phenomena can occur due to the metal parts of the tires, potentially further reducing the maximum reading distance of the RFID devices embedded in the tires.

[0008] To ensure reliable reading of tire RFID devices, manufacturers have proposed applying removable identification labels to the outer surface of the tire (i.e., the tire tread). These labels support additional, temporary RFID devices (which are obviously removed once the tire is initially mounted to the corresponding rim), and because these RFID devices are not obscured by the tire (located on the outside), they are reliably readable from a greater distance compared to RFID devices integrated into the tire's structure. However, this solution does not completely eliminate the problem. This is because, when using a forklift equipped with clamps that secure the bundle of tires laterally, the (obviously metal) clamps could completely obscure the RFID devices applied to the tread by covering them, or, in the worst case, even destroy the additional RFID devices applied to the tread. Therefore, at least two identification labels (each supporting an additional, temporary RFID device) should be applied to the tread and positioned approximately 90° apart from each other (in this way, at least one identification label is always free when the bundle of tires is secured laterally by the clamps). However, this solution doubles the cost because two different identification labels must be applied to each tire. Furthermore, according to this solution, each identification label must face the reader's antenna (i.e., the identification label must be on the line of sight (LOS) of the reader's antenna). Therefore, the reader's antenna must be moved around the entire bundle of tires to read the temporary RFID devices on all the tires in the bundle. In fact, when the identification label is on the opposite side of the tire from the reader's antenna, all the metal and "loss material" of the tire will obstruct the identification label (or, in any case, jeopardize the performance of the identification label), making it difficult, if not impossible, to read the corresponding temporary RFID device. [Overview of the project]

[0009] The object of the present invention is to provide a tire equipped with a temporary identification label, which is not affected by the aforementioned drawbacks and is also easy and economical to manufacture.

[0010] According to the present invention, a tire is provided having a temporary identification label as described in the appended claims.

[0011] The present invention also provides a logistics system for managing a tire warehouse and a method for managing a tire warehouse, as described in the appended claims.

[0012] The attached claims describe preferred embodiments of the present invention and constitute an integral part of this specification.

[0013] The present invention will be described below with reference to the accompanying drawings illustrating non-limiting embodiments thereof. [Brief explanation of the drawing]

[0014] [Figure 1] This is a schematic diagram of a warehouse for tires, each with a temporary identification label, which need to be loaded into containers or trucks for delivery to customers. [Figure 2] Figure 1 is a schematic diagram of a bundle of tires in the warehouse. [Figure 3] Figure 1 is a schematic cross-sectional view of a tire obtained from a warehouse, with parts removed for clarity. [Figure 4] Figure 1 is a schematic front view of a temporary identification label attached to a tire obtained in a warehouse. [Figure 5] Figure 1 is a schematic side view of a temporary identification label attached to a tire obtained in a warehouse. [Figure 6] This is a schematic diagram of the warehouse in Figure 1, emphasizing the horizontally oriented bundles of tires, rather than the vertically oriented bundles shown in Figure 1. [Figure 7] Figure 1 is a schematic diagram of a warehouse that includes a modified forklift. [Figure 8] Figure 1 is a schematic diagram of a warehouse that includes a modified forklift. [Modes for carrying out the invention]

[0015] In Figure 1, number 1 represents a warehouse for so-called TBR ("truck and bus radial") tires 2, which need to be loaded into containers or trucks for delivery to customers.

[0016] Inside warehouse 1, there are several support elements 3, each designed to support a vertically oriented bundle of tires 2 at a given distance from the ground (i.e., from the floor of warehouse 1). In other words, the support elements 3 are shelves or racks that support the bundle of tires 2, keeping it elevated off the ground. It should be noted that the bundle of tires 2 can be oriented vertically (for example, as shown in Figure 1) or horizontally (for example, as shown in Figures 6, 7, or 8). In a vertically oriented bundle of tires 2, the tires 2 are placed on top of each other, increasing the height of the bundle. On the other hand, in a horizontally oriented bundle of tires 2, the tires 2 are placed next to each other, increasing the length of the bundle. It is clear that both vertically oriented and horizontally oriented bundles of tires 2 can be present in the same warehouse 1.

[0017] A series of forklifts 4 operate inside the warehouse 1. Specifically, the series of forklifts 4 move bundles of tires 2, in particular placing bundles of tires 2 that have come from the production line onto support elements 3, and removing bundles of tires 2 from support elements 3 to put the bundles of tires 2 into containers or trucks.

[0018] Each forklift 4 is a wheeled operating device and is powered by an electric motor, diesel engine, or gas engine. Each forklift 4 also includes a holding device 5 positioned at the front and designed to pick up bundles of tires 2. In the embodiment shown in the accompanying drawings, the holding device 5 consists of a pair of forks (only one of which is visible in the accompanying drawings) that lift the bundles of tires 2 from the bottom. According to a different embodiment not shown herein, the holding device 5 consists of clamps that secure the bundles of tires 2 laterally.

[0019] As shown in Figures 2 and 3, each tire 2 has an annular shape with a central cavity 6. Furthermore, each tire 2 is equipped with its own persistent RFID device 7 (in particular, a transponder, tag, smart label), i.e., an electronic device (usually passive, i.e., without its own power source) that can store information (in particular, an unambiguous identification code associated with the tire 2) and communicate at radio frequencies. According to a preferred embodiment, each persistent RFID device 7 may store a so-called "Unique Item Identifier (UII)" for use in the tire industry, coded by "SGTIN-96" coding ("96 bits - Serialized Global Trade Item Number") in accordance with the ISO 20910 standard and the "GS1 EPC Tag Data" standard.

[0020] In other words, each persistent RFID device 7 is a small smart label integrated inside the tire 2, known as a reader (or questioning device), and designed to respond to questions made remotely by a suitable mounting or carrying device. The reader enables reading and / or writing of information contained in the persistent RFID device 7 by communicating with it on a radio frequency. As a result, the persistent RFID device 7 is part of a radio read and / or write system that operates according to so-called RFID ("Radio Frequency Identification") technology.

[0021] According to Fig. 3, each tire 2 comprises a toroidal carcass 8 formed of a main body ply 9, which is partially folded over on itself and thus has two "turned-up portions" (i.e., two overlapping layers) on both sides. In each turned-up portion of the main body ply 9, the edge portion (i.e., the terminal end) of the main body ply 9 abuts an intermediate portion of the main body ply 9.

[0022] On both sides of the carcass 8, there are two annular beads 10, each surrounded by the main body ply 9 (i.e., surrounded by the turned-up portion of the main body ply 9), and each comprising a bead core 11 reinforced with a plurality of metal wire loops and a bead filler 12. In other words, the bead core 11 is formed of steel wires embedded in rubber, and ensures complete coupling between the tire 2 and a rim. As a result, each bead core 11 is essentially made of a metallic material. That is, each bead core 11 is a metal body covered by a relatively thin rubber layer.

[0023] The carcass 8 supports an annular tread 13. Interposed between the carcass 8 and the tread 13 is a tread belt 14 provided with two tread plies 15. Each tread ply 15 is provided with a plurality of cords (not shown), these cords are embedded in a rubber belt, arranged side by side with each other at a given pitch, and form an inclination angle determined relative to the equatorial plane of the tire 2.

[0024] Inside the main body ply 9, there is an inner liner 16 that is air-impermeable, forms an inner coating, and has the function of retaining air inside the tire 2 to maintain the tire pressure of the tire 2 for a long period of time.

[0025] The main body ply 9 supports a pair of sidewalls 17 arranged outside the main body ply 9 between the tread 13 and the beads 10.

[0026] Finally, the main ply 9 supports a pair of wear gum strips 18 located on the outside below the side wall 17 and around the bead 10.

[0027] A persistent RFID device 7 is integrated (embedded) inside each tire 2, particularly around the side wall 17 (for example, the outer side wall 17, i.e., the side wall that faces outward when the tire 2 is mounted on the rim).

[0028] As shown in Figures 2 and 3, each tire 2 also has an identification label 19, which supports a temporary RFID device 20 that is removable and can be read remotely, (at least) by adhesive (shown in Figure 4). In each tire 2, the permanent RFID device 7 is integrated inside the tire 2 and therefore remains attached to the tire 2 at all times (and is used when the tire 2 is mounted on the rim), while the temporary RFID device 20 is used only inside the warehouse 1 and, if necessary, also during the transport of the tire 2 to the end user, but is usually removed from the tire 2 before the tire 2 is mounted on the rim (and therefore discarded). The temporary RFID device 20 is a "substitute" for the permanent RFID device 7, i.e., a "duplicate" of the permanent RFID device 7, used to make it (much) easier to read when the tires 2 are bundled together (as described below). As a result, the temporary RFID device 20 includes at least some of the information contained in the permanent RFID device 7, and in particular always includes information that can identify the tire 2 (e.g., its serial number). Specifically, the temporary RFID device 20 includes the so-called "Unique Item Identifier (UII)" mentioned above.

[0029] In each tire 2, the identification label 19 (supporting the temporary RFID device 20) is positioned around the annular bead 10, and in particular, radially overlaps with the bead core 11 (preferably, though not required, the identification label 19 radially overlaps with only one bead core 11, i.e., does not extend beyond the bead core 11 and therefore does not reach the bead filler 12). Figure 3 shows two different (and perfectly equal) positions of the identification label 19 in the tire 2. The identification label 19 may be attached to the outer edge of the annular bead 10, or the identification label 19 may be attached to the inner edge of the annular bead 10. Although Figure 3 shows two identification labels 19 in two different positions, it is clear that in practice only a single identification label 19 is present. It should be noted that the identification label 19 is positioned around the bead core 11 (i.e., it overlaps with the bead core 11 radially), but does not come into direct contact with the bead core 11 because the outside of the bead core 11 is covered by the wear gum strip 18.

[0030] As shown in Figures 3, 4, and 5, each identification label 19 has an outer portion 21 (i.e., positioned further outward in the radial direction) that is fixed (glued) to the periphery of the bead core 11 (i.e., radially overlapping with the bead core 11), and an inner portion 22 (i.e., positioned further inward in the radial direction) that protrudes unrestricted, i.e., like a flag, from the annular edge portion of the central cavity 6 of the tire 2 to the center point of the central cavity 6. As a result, in each identification label 19, the outer portion 21 of the identification label 19 has a connecting surface that is fixed (in particular, glued using adhesive 23) to the periphery of the bead core 11. On the other hand, in each identification label 19, the inner portion 22 of the identification label 19 is completely free and hangs down the periphery. That is, the entire surface of the inner portion 22 is in the air and does not contact any part of the tire 2.

[0031] Each identification label 19 is fixed (glued) to the outer surface of the tire 2 using adhesive 23, so that the identification label 19 can then be removed in a relatively simple manner. For example, by using a non-drying, re-adhesive adhesive 23, the identification label 19 can be removed relatively easily from the corresponding outer surface of the tire 2.

[0032] According to a preferred (but unrestricted) embodiment shown in Figure 4, each temporary RFID device 20 comprises an antenna including an element 24 located on the outer portion 21 (and thus on one side adjacent to the bead core 11) and an element 25 located on the inner portion 22 (and thus entirely in the air). According to the drawing, elements 24 and 25 each consist of a flat, rectangular (conductive) metal plate.

[0033] Furthermore, element 24 is preferably larger than element 25. In particular, element 24 is extended by 5 to 10 times the size of element 25. Element 24 of the antenna of each temporary RFID device 20 is positioned around the bead core 11, and to improve the performance of the antenna of the temporary RFID device 20, the metal components of the bead core 11 are used as part of the radiating or radiator element (i.e., as antenna components). In the embodiment shown in Figure 4, the antenna of the temporary RFID device 20 has a monopole antenna structure, where element 24 is the ground plate, and element 25 or the radiating or radiator element is meandering to minimize its dimensions. In particular, the two elements 24 and 25 of the antenna of the temporary RFID device 20 are obtained using linear conductors through which current flows to remotely irradiate the electromagnetic field. Furthermore, each temporary RFID device 20 is connected to two antennas 24 and 25 and includes a microchip 26 (i.e., a miniature electronic circuit) with non-volatile memory (typically EEPROM or FRAM memory, the latter being more expensive but more technologically advanced). The microchip 26 is equipped with an automatic tuning mechanism that can automatically adjust its internal impedance to optimize and improve readability, thereby increasing tolerance in the production and positioning of the identification labels 19.

[0034] Each identification label 19 houses a temporary RFID device 20 and includes a support material 27, typically consisting of a thin sheet of plastic such as Mylar, PET, or PVC, or other similar material.

[0035] In the embodiment shown in the attached drawings, each tire 2 comprises both a permanent RFID device 7 integrated inside the tire 2 and a temporary RFID device 20 attached to the outside of the tire 2 (at least). According to a different variation, the tire 2 may comprise only the temporary RFID device 20 attached to the outside of the tire 2 (at least). That is, the tire 2 may not have the permanent RFID device 7 integrated inside the tire 2.

[0036] According to a preferred embodiment shown in Figure 2, a reader device 28, each comprising an electronic control unit 29 and an antenna 30, is positioned in a fixed location within the warehouse 1. Each antenna 30 operates to radiate / receive RF signals having frequencies in the Ultra High Frequency (UHF) band, preferably within the frequency range of 860 to 960 MHz, more preferably within a partial frequency range of 865 to 868 MHz and / or a partial frequency range of 902 to 928 MHz. Furthermore, optional requirements for each antenna 30 include gain greater than 0 dB and circular polarization.

[0037] According to Figure 1, some antennas 30 are positioned horizontally at a given height (higher than the maximum height of the bundle of tires 2) to read the temporary RFID devices 20 of the vertically bundled tires 2. According to Figure 6 or 8, some antennas 30 are positioned vertically in a location deemed appropriate for reading the temporary RFID devices 20 of the horizontally bundled tires 2. For example, one or two antennas 30 may be positioned on either side of a door / gate through which a support element 3 supporting at least one horizontally positioned bundle of tires 2 passes. Generally speaking, horizontal antennas 30 are capable of reading the temporary RFID devices 20 of the vertically bundled tires 2 (as shown in Figure 8), or vertical antennas 30 are capable of reading the temporary RFID devices 20 of the horizontally bundled tires 2. In fact, to effectively read the temporary RFID devices 20 of the bundled tires 2, the antennas 30 must face the central cavity 6 of the stacked tires 2 so that all corresponding temporary RFID devices 20 located within the central cavity 6 are "visible". As a result, the antenna 30 must be oriented horizontally and positioned above or below the bundle so that all temporary RFID devices 20 on the vertical bundle of tires 2 are "visible". On the other hand, the antenna 30 must be oriented vertically and positioned beside the bundle so that all temporary RFID devices 20 on the horizontal bundle of tires 2 are "visible".

[0038] In other words, each bundle of identified tires 2 is placed near the antenna 30 of the leader device 28, in particular below or next to the antenna 30, and the antenna 30 faces the central cavity 6 of the tires 2 constituting the bundle and is aligned with the central cavity 6.

[0039] According to a preferred embodiment, a single antenna 30 is sufficient to read all temporary RFID devices 20 on the tires 2 of the bundle. That is, the single antenna 30 is positioned at one end (top, bottom, or side) of the bundle. Alternatively, for greater reliability, two antennas 30 can be used to read all temporary RFID devices 20 on the tires 2 of the bundle. That is, the two antennas 30 are positioned opposite each other at two ends (top, bottom, or side) of the bundle.

[0040] However, it should be noted that, theoretically, the antenna 30 is capable of reading the temporary RFID devices 20 on the bundle of tires 2, which are positioned both vertically and horizontally, regardless of their orientation.

[0041] During use, the bundle of tires 2 to be identified is placed within the reading area of ​​the antenna 30 of the reader device 28 (i.e., below or beside the antenna 30) so that the reader device 28 can read the temporary RFID devices 20 of all the tires 2. In particular, the bundle of tires 2 (usually transported by the holding device 5 of the forklift 4) may be briefly stopped around the antenna 30 of the reader device 28, or may be moved slowly forward around the antenna 30 of the reader device 28. If, in addition to reading the temporary RFID devices 20 of all the tires 2, the reader device 28 also reads one or more permanent RFID devices 7, the reading of the permanent RFID devices 7 would simply be redundant compared to the reading of the temporary RFID devices 20 and could be ignored as a "substitute" without causing any problems. In particular, according to the "RFID EPC Gen2 GS1" protocol, when two RFID devices 7 and 20, which have the same name and therefore no unique EPC, are read, only one RFID device 7 or 20 present in the reading area will be indicated following the question from the reader device 28.

[0042] Therefore, it is clear that warehouse 1 is equipped with a logistics system, and the handling of tires 2 is highly automated and managed thanks to the autonomous reading of temporary RFID devices 20 coupled to tires 2 (i.e., without manual intervention by operators). In particular, the reader device 28 is connected to the control server 31 of warehouse 1 (schematically shown in Figure 1). The control server 31 is also connected to a tablet computer 32 (or similar portable device) used by the operators of forklift 4. Through the tablet computer 32, the operators of forklift 4 receive operational instructions from the control server 31, communicate the execution of assigned tasks to the control server 31, and update the status of warehouse 1, i.e., the status of tires 2 stored, retrieved, and currently present in warehouse 1, in real time. In other words, the control server 31 activates management software that manages communication between the reader device 28 and the human operators (some of the operators driving forklift 4).

[0043] In a possible (but non-binding) embodiment, in order for the operator of the forklift 4 to quickly and confidently confirm that the reader device 28 has read all of the temporary RFID devices 20 on the tires 2 that make up the bundle of TBR truck tires 2 being transported by the holding device 5 (a bundle of TBR tires 2, typically consisting of 5 to 8 TBR tires 2, placed on top of each other or next to each other depending on the size of the tires 2), the operator must each time use the tablet computer 32 to input (enter) the numbers of the tires 2 loaded into the holding device 5 (the software installed on the tablet computer 32 may proactively suggest to the operator a predefined and limited selection of the numbers of the tires 2 loaded into the holding device 5). The software installed on the tablet computer 32 checks whether the numbers of the temporary RFID devices 20 read by the reader device 28 correspond to (i.e., are identical to) the numbers of the tires 2 loaded into the holding device 5 of the forklift 4 (provided by the operator). If the numbers are identical, the software provides a positive signal (for example, using green light) and completes the reading operation performed by the temporary RFID device 20. On the other hand, if the numbers are not identical, the software provides a negative signal (for example, using red light and an audible warning) and must repeat the reading operation performed by the temporary RFID device 20.

[0044] It should also be noted that the same leader device 28 may be equipped with several antennas 30 positioned in different locations (but in any case close to each other) and activated at different moments by an electronic control unit. In this way, the multiple antennas 30 allow the operator to cover a relatively large area around a predetermined set route, so that the driver of the forklift 4 transporting the bundle of tires 2 does not need to follow the predetermined set route precisely, and may even deviate from the predetermined set route (more or less by accident).

[0045] In the embodiments shown in Figures 1, 2, and 6, the antenna 30 of the leader device 28 is positioned in a fixed location inside the warehouse 1. That is, the antenna 30 of the leader device 28 is mounted on a fixed structure of the warehouse 1. In the variations shown in Figures 7 and 8, at least one leader device 28 is mounted on a forklift 4. In particular, the forklift 4 is equipped with a support device 33 (for example, mounted on the roof of the forklift 4). The support device 33 supports the antenna 30 and positions the antenna 30 near (typically, but not necessarily, on) the bundle (or multiple bundles of tires 2) being transported by the holding device 5 of the forklift 4. The support device 33 may also have a telescopic arm that moves the antenna 30 near (typically, but not necessarily, on) the bundle (or multiple bundles of tires 2) being transported by the holding device of the forklift 4 only when necessary. The antenna 30 (or multiple antennas 30) of the leader device 28 installed on the forklift 4 may also be mounted on the frame of the holding device 5.

[0046] The embodiments described herein can be combined with each other without exceeding the scope of protection of the present invention for the reasons described herein.

[0047] The aforementioned tire 2 has numerous advantages.

[0048] Firstly, the aforementioned tires 2 enable efficient (rapid) and effective (confident) identification of all tires 2 constituting the bundle using a reader device 28 equipped with a single antenna 30 positioned in a fixed location (thus using a simple, economical, and easy-to-use reader device 28). This result is obtained by the specific positioning of the identification label 19, which is always confidently readable, even when the tires 2 are stacked. In fact, the central cavity 6 of the tire 2 (where the identification label 19 is located) is always free from electromagnetic shielding (due to the Faraday cage created by the metal elements of the tire 2), even when the stacked tires 2 are handled.

[0049] Furthermore, certain configurations of the antennas 24 and 25 of the temporary RFID device 20 allow the effective reading distance of the temporary RFID device 20 to be extended by utilizing the metal mass portion of the tire 2 (i.e., the bead core 11), and the metal mass portion is not a concern (for reading the permanent RFID device 20) but a beneficial element (for reading the temporary RFID device 20). Several experiments have shown that a reader device 28 with a single antenna 30 oriented horizontally or vertically can read the temporary RFID devices 20 on all tires 2 in a bundle up to a distance of 6-8 meters from the tire 2 furthest from the antenna 30.

[0050] In addition, the positioning of the identification label 19 within the tire 2 (i.e., around the central cavity 6 of the tire 2, protruding inward from the bead 10) ensures that the identification label 19 is securely protected and therefore substantially unaffected by damage or unintentional detachment. In fact, the area of ​​the bead 10 is never in contact with the identification label 19 in any way during handling.

[0051] Finally, because the temporary RFID device 20 can have relatively small antennas 24 and 25 (since it utilizes parts of the metal mass of the tire 2), the identification label 19 is inexpensive (and therefore accounts for only a small portion of the total manufacturing cost of the tire).

[0052] Furthermore, it should be noted that, regardless of the orientation of the tires 2 and how the bundle is held, a single identification label 19 is always sufficient because it can always be read from above, even if there is only one. In any case, it should be noted that combining a single tire 2 with two or more identification labels 19 is not prohibited (even if it is substantially redundant).

[0053] While the present invention finds advantageous applications in handling so-called TBR ("truck and bus radial") tires 2, in any case, the present invention can be applied to any type of tire 2 (larger or smaller than so-called TBR tires 2). [Explanation of symbols]
