Description

本発明は、タイヤの加硫方法に関し、さらに詳しくは、グリーンタイヤ膨径時の加圧条件を容易に決定することができるタイヤ加硫方法に関する。   The present invention relates to a tire vulcanizing method, and more particularly, to a tire vulcanizing method capable of easily determining a pressing condition when a green tire is inflated.

一般に、空気入りタイヤは、加硫工程において、タイヤ加硫機に取り付けた加硫用金型内にグリーンタイヤをセットした後、ブラダーを膨張させてセットしたグリーンタイヤを膨径し、加硫用金型内側の成型面に接触させた状態で加硫するようにしている（例えば、特許文献１参照）。   In general, pneumatic tires are used for vulcanization in the vulcanization process, after setting a green tire in a vulcanization mold attached to a tire vulcanizer, inflating the bladder and expanding the set green tire. Vulcanization is performed in contact with the molding surface inside the mold (see, for example, Patent Document 1).

ところで、ブラダーなどを用いた加硫では、タイヤ構造の違いにより、グリーンタイヤ膨径時にグリーンタイヤのトレッド部の両ショルダー部がセンター部より先に加硫用金型内側の成型面に接触する場合がある。このようにして成型されたタイヤは、トレッド部に配置した補強層（ベルト層など）の両端部が先に押さえ込まれた状態となるため、加硫後のタイヤにおいて補強層のコードの角度がショルダー部とセンター部で相違し、タイヤ性能に悪影響を与える。   By the way, in vulcanization using a bladder or the like, due to the difference in tire structure, when the shoulders of the tread part of the green tire come into contact with the molding surface inside the vulcanization mold before the center part when the green tire expands There is. In the tire molded in this way, both ends of the reinforcing layer (belt layer, etc.) arranged in the tread portion are pressed first, so that the angle of the cord of the reinforcing layer is shouldered in the vulcanized tire. The tire part is different from the center part and adversely affects the tire performance.

従来、この問題は、ブラダー内に付与する圧力を徐々に高めることにより、解決することができる。しかし、加圧速度が遅いと、その分加硫時間が増加し、生産性の低下を招く。そこで、新たに開発した構造のタイヤでは、グリーンタイヤ膨径時の加圧条件を決定するに当たり、ブラダーの内圧を様々に変更して多数の試験タイヤを加硫し、それを切断して補強層の状態を調べることにより、ショルダー部とセンター部が接触する状況を判断し、それに基づいて、加硫時間の増加を極力抑えながら上記問題が発生しない適正な加圧条件を決定するようにしている。   Conventionally, this problem can be solved by gradually increasing the pressure applied in the bladder. However, when the pressurization speed is slow, the vulcanization time is increased correspondingly and the productivity is lowered. Therefore, in the newly developed tire, when determining the pressurizing conditions when the green tire is inflated, various test tires were vulcanized by varying the internal pressure of the bladder, and the test tire was cut and reinforced. By examining the state of this, the situation where the shoulder portion and the center portion are in contact with each other is determined, and based on this, an appropriate pressurizing condition that does not cause the above problem is determined while suppressing an increase in vulcanization time as much as possible. .

しかしながら、その作業が煩雑で、かつ多数のタイヤを無駄にする問題があり、その対策が強く求められていた。
特開２００５−６６８４８号公報 However, there is a problem that the work is complicated and a large number of tires are wasted, and countermeasures have been strongly demanded.
JP 2005-66848 A

本発明の目的は、煩雑な作業や多数のタイヤを無駄にすることなく、グリーンタイヤ膨径時の加圧条件を容易に決定することが可能なタイヤ加硫方法を提供するものである。   An object of the present invention is to provide a tire vulcanizing method capable of easily determining the pressurizing condition at the time of expanding a green tire without wasting a complicated operation and a large number of tires.

上記目的を達成する本発明のタイヤ加硫方法は、グリーンタイヤのトレッド部のセンター部外表面と両ショルダー部外表面にそれぞれセンサーを配置し、該グリーンタイヤをタイヤ加硫用金型内にセットした後、膨径してタイヤ加硫用金型内側の成型面に接触させて加硫するタイヤ加硫方法であって、グリーンタイヤ膨径時に前記センサーにより該センサーを配置した外表面が前記成型面と接触する順序を検出することを特徴とする。   In the tire vulcanizing method of the present invention that achieves the above object, sensors are arranged on the outer surface of the center portion and the outer surfaces of both shoulder portions of the tread portion of the green tire, and the green tire is set in a tire vulcanizing mold. Then, the tire vulcanizing method in which the swell is brought into contact with the molding surface inside the tire vulcanizing mold and vulcanized, and the outer surface where the sensor is arranged by the sensor when the green tire swells is formed by the molding. The order of contact with the surface is detected.

上述した本発明によれば、トレッド部のセンター部外表面と両ショルダー部外表面にそれぞれ配置したセンサーにより、グリーンタイヤ膨径時にセンサーを配置した外表面が成型面に接触する順序を検出することで、膨径時にトレッド部のセンター部とショルダー部が成型面に接触する状況（順番及び時間差）を知ることができ、グリーンタイヤ膨径時の加圧条件を決定する上で重要な情報を容易に得ることができる。そのため、新たに開発した構造のタイヤにおいて、従来の煩雑な作業やタイヤの無駄を生じることなく、グリーンタイヤ膨径時の加圧条件を容易に決定することができる。   According to the present invention described above, the sensor disposed on the outer surface of the center portion and the outer surfaces of both shoulder portions of the tread portion detects the order in which the outer surface on which the sensor is disposed contacts the molding surface when the green tire is inflated. Therefore, it is possible to know the situation (order and time difference) where the center part and shoulder part of the tread part come into contact with the molding surface at the time of expansion, and it is easy to obtain important information for determining the pressure conditions at the time of green tire expansion Can get to. Therefore, in a tire having a newly developed structure, it is possible to easily determine the pressurizing condition at the time of expanding the green tire without causing the conventional troublesome work and waste of the tire.

以下、本発明の実施の形態について添付の図面を参照しながら詳細に説明する。
図１は本発明のタイヤ加硫方法の一実施形態を示し、Ｍはタイヤ加硫用金型、１，２は環状の上下の金型、３はその間に環状に配置したセクター、４，５は上下のビードリングである。また、６はブラダー、７はグリーンタイヤである。 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 shows one embodiment of a tire vulcanizing method of the present invention, where M is a tire vulcanizing mold, 1 and 2 are annular upper and lower molds, 3 is an annularly arranged sector, 4, 5 Is the upper and lower bead rings. Reference numeral 6 is a bladder, and 7 is a green tire.

図１に示す本発明のタイヤ加硫方法は、先ず、図２に示すように、グリーンタイヤ７の外表面７ｘにグリーンタイヤ７が金型Ｍの成型面Ｍａと接触したのを検出するためのセンサー８を貼り付ける。センサー８を配置する部位は、図示する例では、トレッド部７Ａのセンター部７Ａ１と両ショルダー部７Ａ２の外表面７ｘｍ，７ｘｎ、及び両サイドウォール部７Ｂの外表面７ｘｂと両ビード部７Ｃの外表面７ｘｃに配置するようにしているが、少なくともトレッド部７Ａのセンター部７Ａ１と両ショルダー部７Ａ２の外表面７ｘｍ，７ｘｎに配置するようにする。なお、図２に示すグリーンタイヤ７は、図１に示すカーカス層７１やベルト層７１などのタイヤ構成部材を省略している。   In the tire vulcanizing method of the present invention shown in FIG. 1, first, as shown in FIG. 2, the green tire 7 is detected on the outer surface 7x of the green tire 7 in contact with the molding surface Ma of the mold M. A sensor 8 is pasted. In the illustrated example, the sensor 8 is disposed at the center portion 7A1 of the tread portion 7A and outer surfaces 7xm and 7xn of both shoulder portions 7A2, and the outer surfaces 7xb of both sidewall portions 7B and the outer surfaces of both bead portions 7C. Although it is arranged at 7xc, it is arranged at least on the outer surface 7xm, 7xn of the center portion 7A1 of the tread portion 7A and both shoulder portions 7A2. In the green tire 7 shown in FIG. 2, tire constituent members such as the carcass layer 71 and the belt layer 71 shown in FIG. 1 are omitted.

センサー８を配置した後、通常通りに加硫する。即ち、不図示のローダでグリーンタイヤ７をタイヤ加硫機まで搬送し、そこで所定の高さに保持する。ブラダー６内に加圧媒体を供給してブラダー６をグリーンタイヤ７の空洞部内で膨張させる。膨張したブラダー６によりグリーンタイヤ７を内側から保持すると、ローダが離間し、続いて上型１とセクター３が移動して閉型し、グリーンタイヤ７を金型Ｍ内にセットする。   After placing the sensor 8, vulcanize as usual. That is, the green tire 7 is conveyed to a tire vulcanizer by a loader (not shown), and is held at a predetermined height there. A pressurized medium is supplied into the bladder 6 to expand the bladder 6 in the cavity of the green tire 7. When the green tire 7 is held from the inside by the expanded bladder 6, the loader is separated, and then the upper mold 1 and the sector 3 are moved and closed, and the green tire 7 is set in the mold M.

グリーンタイヤ７がセットされると、ブラダー６内に更に高圧の加圧媒体と加熱媒体が供給され、膨張したブラダー６によりセットしたグリーンタイヤ７を膨径して、金型Ｍ内側の成型面Ｍａに順次押し当て接触させる。図１は、両ビード部１Ｃがビードリング４，５の成型面４ａ，５ａに接触した後、トレッド部７Ａの両ショルダー部７Ａ２がセクター３の成型面３ａに接触した状態を示している。   When the green tire 7 is set, a higher pressure medium and a heating medium are supplied into the bladder 6, the diameter of the set green tire 7 is expanded by the expanded bladder 6, and the molding surface Ma inside the mold M is expanded. Press and contact with each other. FIG. 1 shows a state in which both shoulder portions 7A2 of the tread portion 7A are in contact with the molding surface 3a of the sector 3 after both bead portions 1C are in contact with the molding surfaces 4a and 5a of the bead rings 4 and 5.

グリーンタイヤ７が膨径して外表面の部位が成型面Ｍａに順次接触すると、それに伴って、グリーンタイヤ７の外表面７ｘに配置したセンサー８が順次成型面Ｍａに接触する。センサー８が接触すると、センサー８がオンになり、センサー８を配置したグリーンタイヤ７の外表面７ｘの部分が成型面Ｍａに接触したことを知らせる。これによりグリーンタイヤ７がセンサー８を配置したどの部位から順番に成型面Ｍａに接触するかが容易にわかり、またその接触する時間差も知ることができる。   When the green tire 7 expands and the outer surface portion sequentially contacts the molding surface Ma, the sensor 8 disposed on the outer surface 7x of the green tire 7 sequentially contacts the molding surface Ma. When the sensor 8 comes into contact, the sensor 8 is turned on to notify that the portion of the outer surface 7x of the green tire 7 on which the sensor 8 is disposed has come into contact with the molding surface Ma. As a result, it can be easily understood from which part the green tire 7 is placed with the sensor 8 in order to contact the molding surface Ma, and the time difference between the contact can also be known.

例えば、センター部７Ａ１に配置したセンサー８ａが１０秒後にオンになり、ショルダー部７Ａ２に配置したセンサー８ｂが１２秒後にオンになる場合には、トレッド部７Ａのセンター部７Ａ１が先に成型面Ｍａに接触し、接触する時間差が２秒であることがわかる。また、ショルダー部７Ａ２に配置したセンサー８ｂが１１秒後にオンになり、センター部７Ａ１に配置したセンサー８ａが１２秒後にオンになる場合には、トレッド部７Ａのショルダー部７Ａ２が先に成型面Ｍａに接触し、接触する時間差が１秒であることがわかる。   For example, when the sensor 8a disposed on the center portion 7A1 is turned on after 10 seconds and the sensor 8b disposed on the shoulder portion 7A2 is turned on after 12 seconds, the center portion 7A1 of the tread portion 7A is first molded surface Ma. It can be seen that the difference in contact time is 2 seconds. When the sensor 8b arranged on the shoulder portion 7A2 is turned on after 11 seconds and the sensor 8a arranged on the center portion 7A1 is turned on after 12 seconds, the shoulder portion 7A2 of the tread portion 7A is first molded surface Ma. It can be seen that the difference in contact time is 1 second.

膨張させたブラダー６によりグリーンタイヤ７の外表面７ｘ全体が成型面Ｍａに接触し、グリーンタイヤ７が金型Ｍ内で成型面Ｍａに内側から押圧された状態で加硫される。加硫終了後、金型Ｍ内から加硫済のタイヤを取り出して、タイヤの加硫工程が終了する。   The entire outer surface 7x of the green tire 7 is brought into contact with the molding surface Ma by the expanded bladder 6, and the green tire 7 is vulcanized in the mold M while being pressed against the molding surface Ma from the inside. After the vulcanization is completed, the vulcanized tire is taken out from the mold M, and the tire vulcanization process is completed.

このように本発明では、トレッド部７Ａのセンター部７Ａ１の外表面７ｘｍと両ショルダー部７Ａ２の外表面７ｘｎにそれぞれ配置したセンサー８により、グリーンタイヤ膨径時にセンサー８を配置した各部分の外表面が成型面Ｍａと接触する順序を検出するようにしたので、膨径時にグリーンタイヤ７のショルダー部７Ａ２とセンター部７Ａ１が成型面Ｍａに接触する状況（順番及び時間差）、即ちグリーンタイヤ膨径時の加圧条件を決定する上で重要な情報を容易に得ることができる。そのため、新たに開発した構造のタイヤにおける従来の煩雑な作業やタイヤの無駄を生じることなく、グリーンタイヤ７の膨径時の加圧条件を容易に決定することが可能になる。   As described above, according to the present invention, the outer surfaces 7xm of the center portion 7A1 of the tread portion 7A and the outer surfaces 7xn of the shoulder portions 7A2 are respectively provided with the sensors 8, and the outer surfaces of the portions where the sensors 8 are disposed when the green tire is inflated. Since the order of contact with the molding surface Ma is detected, the situation (order and time difference) where the shoulder portion 7A2 and the center portion 7A1 of the green tire 7 are in contact with the molding surface Ma at the time of expansion, that is, when the green tire is expanded. It is possible to easily obtain important information for determining the pressurizing conditions. Therefore, it is possible to easily determine the pressurizing condition when the green tire 7 is inflated without causing the conventional troublesome work and tire waste in the newly developed tire.

本発明において、上記センサー８としては、オン・オフスイッチなどを使用することができるが、好ましくは、成型面Ｍａとの接触圧を検出可能な圧力センサーを用いるのがよい。圧力センサーにより接触圧を時系列的に検出することにより、加硫中におけるグリーンタイヤ７の接触状態（接触圧力）も知ることができるので、上述した膨径時の加圧条件に加えて、この接触状態に基づいて加硫条件（加硫時間、加硫圧力、加硫温度）を設定することができ、それにより適正な加硫が可能となるため、加硫されたタイヤのゴム物性を向上し、かつ耐久性の改善が可能となる。   In the present invention, an on / off switch or the like can be used as the sensor 8. Preferably, a pressure sensor that can detect a contact pressure with the molding surface Ma is used. By detecting the contact pressure in time series with the pressure sensor, the contact state (contact pressure) of the green tire 7 during vulcanization can also be known. The vulcanization conditions (vulcanization time, vulcanization pressure, vulcanization temperature) can be set based on the contact state, which enables proper vulcanization and improves the rubber properties of the vulcanized tire In addition, durability can be improved.

センサー８に使用する圧力センサーとしては、変形を許容する必要があるため、図３に示すように、配線基板９上に検出素子として感圧導電ゴム１０を配置したものを好ましく使用することができる。感圧導電ゴム１０は円板状に形成するのがよく、その寸法としては、ゴムの変形速度を考慮すると、直径Ｄ５ｍｍ以上、厚さｔ０．５ｍｍ〜２．０ｍｍのものが、良好な測定精度を確保する上でよい。直径Ｄの上限値としては、設置可能であれば特に限定されるものではないが、測定部位の精度維持の点から１５ｍｍ以下にするのがよい。   As the pressure sensor used for the sensor 8, since it is necessary to allow deformation, a sensor in which a pressure-sensitive conductive rubber 10 is arranged as a detection element on the wiring board 9 can be preferably used as shown in FIG. 3. . The pressure-sensitive conductive rubber 10 is preferably formed in a disk shape, and the dimensions thereof are those with a diameter of D5 mm or more and a thickness of t0.5 mm to 2.0 mm with good measurement accuracy in consideration of the deformation speed of the rubber. It is good in securing. The upper limit of the diameter D is not particularly limited as long as it can be installed, but is preferably 15 mm or less from the viewpoint of maintaining the accuracy of the measurement site.

センサー８は、サイドウォール部７Ｂ及びビード部７Ｃの外表面７ｘｂ，７ｘｃには、上述した本発明の目的を達成するためには特に配置する必要はないが、センサー８に圧力センサーを使用し、その接触状態に基づいて加硫条件を設定する場合には配置するのがよい。その場合、必要に応じて、サイドウォール部７Ｂ及び／またはビード部７Ｃに配置するようにすればよい。   The sensor 8 does not need to be particularly arranged on the outer surfaces 7xb and 7xc of the sidewall portion 7B and the bead portion 7C in order to achieve the above-described object of the present invention, but a pressure sensor is used for the sensor 8, When setting vulcanization conditions based on the contact state, it is preferable to arrange them. In that case, what is necessary is just to arrange | position to the side wall part 7B and / or the bead part 7C as needed.

センサー８は、上記実施形態では、周方向において各部位でそれぞれ１つ配置した例を示すが、必要に応じて周方向に複数個配置するようにしてもよい。   In the embodiment described above, one sensor 8 is disposed at each site in the circumferential direction, but a plurality of sensors 8 may be disposed in the circumferential direction as necessary.

本発明のタイヤ加硫方法は、上記のように膨径時の加圧条件や加硫条件を設定する際に好適に使用することができるが、それに限定されず、定期的にタイヤの膨径時の加圧条件や加硫条件をチェックする場合にも好ましく用いることができる。   The tire vulcanization method of the present invention can be suitably used when setting the pressure conditions and vulcanization conditions at the time of expansion as described above. It can also be preferably used when checking the pressurizing conditions and vulcanizing conditions.

本発明で使用するタイヤ加硫用金型Ｍは、上述した上型１、下型２、セクター３を備えたセクショナルタイプに限定されず、グリーンタイヤ７の一方の半分を成型する上型と他方の半分を成型する下型を備えた２分割構造の金型であってもよい。   The tire vulcanization mold M used in the present invention is not limited to the above-described sectional type including the upper mold 1, the lower mold 2, and the sector 3, but the upper mold for molding one half of the green tire 7 and the other mold. It may be a two-part mold having a lower mold that molds half of the mold.
