Description

  The present invention relates to a golf ball incorporating an IC chip such as an RFID (radio-frequency identification) chip.

  Attempts have been made to incorporate an IC chip into a golf ball in order to record information about the ball, such as the material, manufacturing location, and manufacturing date of the golf ball.

  For example, Patent Document 1 discloses that an RFID circuit and an antenna connected to the surface of a golf ball cover are made of conductive ink on the surface of the golf ball cover in order to prevent damage to the IC chip incorporated even when the golf ball is hit. It is disclosed to form.

JP 2013-154176 A

  Usually, in order to transmit and receive information by wireless communication, a metal antenna is connected to a silicon IC chip. Although small IC tags with an antenna built into an IC chip are currently available, such IC tags have short antennas, so if they are built into a golf ball, the communication distance is short and cannot be easily read by a reader. . Therefore, when incorporated in a golf ball, it is necessary to connect a long antenna to the IC chip. However, since the golf ball is greatly deformed instantaneously when hit, there is a problem that the joint between the IC chip and the antenna is particularly easy to break, and communication becomes impossible immediately.

  In view of the above problems, an object of the present invention is to provide a golf ball including an IC chip that can prevent the IC chip embedded in the golf ball from becoming incapable of communication due to impact. .

  In order to achieve the above object, a golf ball incorporating an IC chip according to the present invention includes a core positioned at the center thereof, a cover surrounding the outer periphery of the core, and a position between the core and the cover. An IC tag including an IC chip and a first antenna directly connected to the IC chip, and a second antenna partially surrounded by the IC tag are provided.

  The IC tag and the second antenna need not be in physical contact. The part of the second antenna that is placed around the IC tag is preferably located within 1 mm from the IC tag. The second antenna is preferably placed over at least half of the outer periphery of the IC tag. The second antenna is preferably disposed over at least half of the circumference of the golf ball. The size of the IC chip is preferably 5 mm or less.

  As described above, according to the present invention, the IC tag incorporating the first antenna and the second antenna are provided at a position between the core and the cover of the golf ball, and the second antenna is a part of the IC tag. Is arranged around the IC tag so that the second antenna is physically connected to the IC chip in the IC tag even though it is not physically connected to the IC chip in the IC tag. It functions as an antenna of an IC chip via one antenna, and therefore the communication distance can be greatly increased as compared with the IC tag alone. In addition, since the second antenna is not physically joined to the IC chip or the first antenna, the joined portion is not damaged by the hitting of the golf ball, thereby preventing the communication from being disabled. be able to.

1 is a plan view schematically showing an embodiment of a golf ball according to the present invention. FIG. 2 is a perspective view schematically showing an RFID tag built in the golf ball shown in FIG. 1. FIG. 3 is a schematic cross-sectional view taken along line III-III of the golf ball shown in FIG. 1. It is sectional drawing which shows typically another embodiment of the golf ball which concerns on this invention. It is a perspective view which shows the IC chip which joined the external antenna used for the comparative example.

  Hereinafter, an embodiment of a golf ball incorporating an IC chip according to the present invention will be described with reference to the accompanying drawings. This embodiment is for facilitating understanding of the present invention, and the present invention is not limited to this. Note that the drawings are not drawn to scale in order to prioritize understanding of the present invention.

  As shown in FIG. 1, a golf ball 1 according to the present embodiment includes a core 10 located at the center of the golf ball, a cover 20 that surrounds the outside of the core, and an RFID tag 30 that transmits and receives information by wireless communication. And a boost antenna 40 for the RFID tag. A plurality of dimples (not shown) are formed on the surface of the cover 20.

  As shown in FIG. 2, the RFID tag 30 mainly includes an IC chip 32 for storing and calculating information and a built-in antenna 36 for communicating radio frequency signals. The IC chip 32 and the built-in antenna 36 are physically and directly connected to each other. That is, in this specification, an “RFID tag” or an “IC tag” is an object in which an IC chip and an antenna directly connected to the IC chip are integrally formed, and this antenna is used as a built-in antenna or a first antenna. That's it.

  In this embodiment, as shown in FIG. 2, the RFID tag 30 is formed by integrally forming an IC chip 32 and a built-in antenna 36 on a substrate 34. However, the present invention is not limited to this, for example, The IC chip and the built-in antenna directly connected to the IC chip may be integrally formed with, for example, a sealing material. The shape of the RFID tag is not limited to a flat rectangular parallelepiped as shown in the figure, and may be a disk or the like.

  The size of the RFID tag 30 is preferably as small as possible in order to prevent the center of gravity of the golf ball from deviating from the center of the ball. Specifically, it is preferably 5 mm or less, and more preferably 3 mm or less. For example, in the case of a flat rectangular parallelepiped, the length and width are each preferably 5 mm or less, and more preferably 3 mm or less. In the case of a disc body, the diameter is preferably 5 mm or less, and more preferably 3 mm or less. The thickness is preferably 1 mm or less, more preferably 0.5 mm or less, whether it is a flat rectangular parallelepiped or a disk.

  The IC chip 32 may be a passive type that operates using radio waves received from an external reader (not shown) as an energy source, but may also be an active type that incorporates a battery. In this case, the built-in battery can be charged with a non-contact charger.

  The IC chip 32 is not particularly limited with respect to the frequency band to be used. For example, the IC chip 32 may use a 13.56 MHz band (HF band) or a 952 to 954 MHz band (UHF band).

  Part of the boost antenna 40, particularly the central part 40 a thereof, is placed around the RFID tag 30. In this specification, “peripheral” means that the boost antenna 40 is arranged around the RFID tag 30 as indicated by the letter, and the boost antenna 40 and the RFID tag 30 are physically and electrically connected. However, the boost antenna 40 and the RFID tag 30 may be in non-electrical physical contact. It is preferable to arrange the RFID tag and the boost antenna 40 so that the distance is within 1 mm.

  By arranging the boost antenna 40 with respect to the RFID tag 30 as described above, the IC chip 32 and the boost antenna 40 in the RFID tag 30 are physically connected even when the golf ball 1 is subjected to a strong impact by the hit with the golf club. Since the electrical connection is not made, it is possible to prevent the conventional connection portion between the IC chip and the antenna from being damaged and becoming incapable of communication.

  A portion of the boost antenna 40 is preferably disposed over at least half of the outer periphery of the RFID tag 30 as shown in FIG. Of course, a part of the boost antenna 40 may be disposed so as to surround the entire outer periphery of the RFID tag 30.


The boost antenna 40 is not particularly limited as long as it is a conductive material, but a metal thread or a conductive thread can be used. As the metal yarn, for example, a filament such as gold, silver, copper, or aluminum, or a twisted or knitted filament of these filaments can be used. As the conductive yarn, a yarn in which a fiber such as nylon or polyester is used as a core and a metal such as silver or copper is plated can be used. The content ratio of the metal in the conductive yarn is not particularly limited as long as it is an amount sufficient to ensure conductivity, but for example, a range of 10 to 70% by weight is preferable. Further, in order to maintain the center of gravity position of the golf ball 1 at the center of the ball, the composition of the metal thread or the conductive thread is such that the specific gravity of the boost antenna 40 is the same as the specific gravity of the layer on which the cover 30 or the like is arranged. It is preferable.


The diameter of the boost antenna 40 (metal thread or conductive thread) is not particularly limited, but the upper limit is preferably 1.5 mm or less, and more preferably 1.0 mm or less. Moreover, the lower limit is preferably 0.1 mm or more, and more preferably 0.3 mm or more.

  As shown in FIG. 3, the RFID tag 30 and the boost antenna 40 are disposed between the core 10 and the cover 20. In the two-piece golf ball 1 including the core 10 and the cover 20, the RFID tag 30 is preferably embedded in the groove 12 provided on the surface of the core 10. In this case, the surface of the RFID tag 30 and the surface of the core 10 are used. Are preferably in the same plane.

  The boost antenna 40 is preferably arranged so that the portions 40 b and 40 c on both sides of the boost antenna 40 extend in the opposite direction along the surface of the core 10 from the central portion 40 a that surrounds the RFID tag 30. The lengths of the portions 40b and 40c on both sides are preferably equal. In FIG. 3, the overall length of the boost antenna 40 extends over about ¾ of the circumference of the golf ball 1 to the core 10, but the present invention is not limited to this, and the golf ball 1 to the core 10 has the entire length. It is preferable to arrange the boost antenna 40 over at least half of the circumference. With such a configuration, the communication distance is extended, and the reader can communicate with the RFID tag 30 at any position of the golf ball 1, that is, at the opposite surface of the RFID tag 30.

  The shape or arrangement of the portions 40b and 40c on both sides of the boost antenna is not limited to the above. For example, it may extend to the entire circumference of the golf ball, or may extend in a curved shape instead of a straight shape. Also, considering the symmetry of the golf ball, the boost antenna may be divided into four parts from the central part and extend in an X shape.


The present invention can also be applied to a golf ball having a multi-piece structure. For example, as shown in FIG. 4, when the golf ball includes an intermediate layer 50 between the core 10 and the cover 20, the RFID tag 30 is embedded in a groove 52 provided on the surface of the intermediate layer 50. Is preferred. Further, the boost antenna 40 is preferably arranged such that the portions 40b and 40c on both sides of the boost antenna 40 extend in the opposite direction along the surface of the intermediate layer 50 from the central portion 40a around the RFID tag 30. The intermediate layer 50 is not limited to one layer as shown in FIG. 4, and may be a plurality of layers. In such a multi-piece golf ball, even if a plurality of intermediate layers are provided, the RFID tag and the boost antenna are preferably disposed on the surface of the layer located inside the outermost shell layer (ie, the cover). As a result, a communication distance can be secured. In terms of the diameter of the golf ball, the boost antenna 40 is preferably disposed at a position where the diameter of the golf ball is 42 mm or less, and more preferably at a position where the diameter is 40 mm or less. Moreover, it is preferable to arrange | position the boost antenna 40 in the position of 20 mm or more in diameter of a golf ball, and the position of 30 mm or more is more preferable.

  The core 10 can be mainly formed of rubber. As the main component rubber (base rubber), rubber can be widely used. For example, in addition to polybutadiene rubber (BR), styrene butadiene rubber (SBR), natural rubber (NR), polyisoprene rubber (IR) ), Polyurethane rubber (PU), silicone rubber or the like can be used, but is not limited thereto.

  In addition to such a base rubber, the core 10 optionally contains, for example, a co-crosslinking agent, a crosslinking initiator, a filler, an anti-aging agent, an isomerizing agent, a peptizer, sulfur, and an organic sulfur compound. Can be added. Further, instead of rubber, a resin may be used as a main component, and for example, a thermoplastic elastomer, an ionomer resin, or a mixture thereof can be used.

  The hardness of the core 10 is not particularly limited, but the upper limit is preferably 60 or less, more preferably 50 or less, and even more preferably 40 or less at Shore D. The lower limit of the hardness of the core 10 is preferably 20 or more, more preferably 30 or more in Shore D.

  The core 10 has a substantially spherical shape. The outer diameter of the core 10 is preferably 42 mm or less, more preferably 41 mm or less, and even more preferably 40 mm or less. The lower limit of the outer diameter of the core 10 is preferably 5 mm or more, more preferably 15 mm or more, and most preferably 25 mm or more because the rebound of the golf ball is reduced if it is too small. The core 10 is a solid core in FIG. 3, but is not limited thereto, and may be a hollow core. Moreover, although the core 10 was shown as one layer in FIG. 3, it is not limited to this, For example, it is good also as a core which consists of several layers, such as a center core and its surrounding layer.

  The material for forming the cover 20 is not limited to these, but can be formed by using an ionomer resin, a polyurethane-based thermoplastic elastomer, a thermosetting polyurethane, or a mixture thereof as a main component. Further, as the main component, a two-component curable polyurethane resin may be used. Furthermore, in addition to the main components, other thermoplastic elastomers, polyisocyanate compounds, fatty acids or derivatives thereof, basic inorganic metal compounds, fillers, and the like can be added to the cover 20.

  Although not limited to this as ionomer resin, what uses the following (a) component and / or (b) component as a base resin can be used. Moreover, the following (c) component can be arbitrarily added to this base resin. The component (a) is an olefin-unsaturated carboxylic acid-unsaturated carboxylic acid ester ternary random copolymer and / or a metal salt thereof, and the component (b) is an olefin-unsaturated carboxylic acid binary random copolymer and The metal salt (c) component is a thermoplastic block copolymer having a polyolefin crystal block and a polyethylene / butylene random copolymer.

  As a material of the intermediate layer 50, an intermediate layer having a core function may be provided using the core material described above, or an intermediate layer having a cover function may be provided by using the cover material described above. It may be provided. When providing a plurality of intermediate layers, for example, a first intermediate layer having a core function and a second intermediate layer having a cover function may be provided.

  The golf ball composed of the core 10, the cover 20, and the optional intermediate layer 50 preferably has a predetermined ball hardness. The ball hardness refers to a deflection amount (compression deformation amount) of the golf ball from when the initial load 98N is applied to the golf ball to when the final load 1275N is applied. The unit is expressed in mm. The compression speed is 10 mm / s. The lower the numerical value, the harder the golf ball, and the higher the ball hardness (deflection amount). The ball hardness also affects the feel and durability that a golfer feels when a golf ball is shot. Therefore, the lower limit of the deflection amount is preferably 1.5 mm or more, and the upper limit is preferably 5.0 mm or less.

  Next, an embodiment of a method for manufacturing the golf ball 1 incorporating such an RFID tag 30 and the boost antenna 40 will be described.

  First, the core 10 is formed by a known method for forming a golf ball core. Specifically, although not limited to this, after the material containing the base rubber is kneaded with a kneader, this kneaded product can be obtained by pressure vulcanization molding with a round die. The RFID tag groove 12 on the surface of the core 10 can be formed by the above-described round mold, or can be formed by digging the surface with an excavating tool after the mold is formed. In the groove 12, for example, a commercially available RFID tag 30 having a built-in antenna is disposed.

  Then, a metal thread or conductive thread is disposed on the surface of the core 10 as the boost antenna 40. At this time, the boost antenna 40 is arranged so as to surround at least half of the outer periphery of the RFID tag 30. The distance between the boost antenna 40 and the RFID tag 30 is preferably within 1 mm, and of course, a part of the distance may be in contact.

  Next, the cover 20 is formed by, for example, an injection molding method. Specifically, the core 10 in which the RFID tag 30 and the boost antenna 40 are arranged is placed in the center of the cover mold, and the cover material is injected and introduced into the mold so as to cover the core 10. The cover 20 can be formed. In this way, a golf ball with a built-in RFID tag and boost antenna can be manufactured.

  When an active RFID tag with a built-in battery is used, it is preferable to form a cover by introducing a two-component curable polyurethane resin into a cover mold instead of the injection molding method. By using such a two-component curable resin, it is possible to avoid failure of the battery built in the RFID tag due to heat.

  The production of a golf ball having a multi-piece structure provided with an intermediate layer 50 will be described. When the intermediate layer is formed of a core material, a known method of forming a solid core having a multilayer structure can be employed for forming the intermediate layer. For example, the core 10 obtained by the above method is used as a center core, the core material is further kneaded with a kneader, the kneaded material is formed into a sheet, and the center core is covered with this sheet. By performing pressure vulcanization molding with a round die, a product in which an intermediate layer 50 of the core material is formed on the outer periphery of the center core 10 can be obtained. The RFID tag groove 52 on the surface of the intermediate layer 50 can be formed by the above-described round mold, or can be formed by digging the surface with a drilling tool after the mold is formed. The RFID tag 30 is disposed in the groove 52 and the boost antenna 40 is disposed on the surface of the intermediate layer 50. Then, by forming the cover 20 by an injection molding method or the like, a multi-piece golf ball with a built-in RFID tag and boost antenna can be manufactured.

  Three golf balls each having the configuration shown in Table 1 were manufactured, and a test for measuring the durability of the golf ball and the readability of the built-in RFID tag was performed. As the RFID tag used, Monza5 (frequency band: UHF) manufactured by Hitachi Chemical Co., Ltd. was used. Each of the RFID tags is a flat square, and the dimensions thereof are as shown in Table 1. The boost antenna was placed at a distance of 1 mm or less using conductive yarn (diameter: 0.7 mm) having a composition of 83% nylon and 17% silver so that the central portion surrounds three sides of the RFID tag. The boost antenna was arranged so as to make a half turn of the golf ball (core) at a position of 39.3 mm in diameter of the golf ball.

  For comparison, the same RFID tag as in the example was used, but the boost antenna was not arranged (Comparative Example 1), the RFID tag and the boost antenna were not arranged (Comparative Example 2), As shown in FIG. 5, an external antenna 66 (material: copper) formed in an annular shape having an outer diameter of 11 mm is joined to a commercially available IC chip 62 having no built-in antenna by a connecting material 64 of the same material instead of the RFID tag. The same test as that of the example was performed on the case where the externally attached antenna bonded IC chip 60 was arranged on the core surface (Comparative Example 3). In addition, the materials and blends of the core and cover of the golf ball were common to all of Examples 1 to 3 and Comparative Examples 1 to 3. The core material was rubber, and the cover material was ionomer resin. The cover hardness was D56.

  The ball outer diameter, ball weight, ball hardness, and ball initial speed in Table 1 are all average values of three golf balls. The initial velocity of the ball was measured by a measurement method stipulated in the initial velocity rule of the golf ball using an initial velocity measuring device of the same type as the USGA drum rotation type initial velocity meter.

  The communication distance in Table 1 was measured by using AT-880 manufactured by ATID as an RFID reader, and measuring the distance from the golf ball to which the RFID tag can be read, that is, the distance from the golf ball to the RFID reader.

  COR durability of Table 1 evaluated the durability of a golf ball using an ADC Ball COR Durability Tester machine manufactured by Automated Design Corporation. This test machine has a function of causing a golf ball to be blown with air pressure and then continuously colliding with two metal plates installed in parallel. The incident speed on the metal plate was 43 m / s. The average value of the number of shots required until the ball was broken was defined as COR durability. In this case, the average value is a value obtained by averaging the number of firings required to fire three balls in each example and break the three balls.

  And when the readability of RFID was examined, it was possible to read any of the golf balls of Examples 1 to 3 and Comparative Example 1 until the balls were broken in the COR durability test. On the other hand, in Comparative Example 3 in which an external antenna was physically joined to an IC chip having no built-in antenna, reading was impossible at 10 times far before the ball broke in the COR durability test. Therefore, it has been shown that by providing a boost antenna around an RFID tag having a built-in antenna, it is possible to prevent the RFID tag from being unable to communicate even when a golf ball is hit hard. Further, the durability of the golf ball (Examples 1 to 3) itself in which the RFID tag and the boost antenna are provided in the golf ball in this way is the same as that of a normal golf ball (Comparative Example 2) in which neither the RFID tag nor the boost antenna is provided. It was equivalent.
