Description

本発明は、加硫型にタイヤ製造用熱制御セグメントモールドを備えたタイヤ加硫装置に関する。   The present invention relates to a tire vulcanizing apparatus provided with a thermal control segment mold for manufacturing tires in a vulcanization mold.

タイヤ加硫装置は、一般には、グリーンタイヤをガスによりトロイダル状に膨張させるためのブラダと、ブラダの外周に配置されて、グリーンタイヤを所定形状に成形する金型とを備え、加硫時には、成形金型内にグリーンタイヤを装着した後、上記ブラダ内部に高温高圧の加硫媒体を供給してブラダとグリーンタイヤを一体的にトロイダル状に膨張変形させグリーンタイヤを金型面に押圧して、所定の形状に成形する。   A tire vulcanizing apparatus generally includes a bladder for inflating a green tire in a toroidal shape with gas, and a mold that is disposed on the outer periphery of the bladder and molds the green tire into a predetermined shape. After mounting the green tire in the mold, supply a high-temperature and high-pressure vulcanizing medium inside the bladder to inflate and deform the bladder and the green tire into a toroidal shape and press the green tire against the mold surface. Then, it is formed into a predetermined shape.

この成形の際に、加硫時間を短縮して生産性を向上するため上記金型を所定の温度まで加熱して、金型により上記グリーンタイヤをその外周面側から均一に加熱し、同時に加熱媒体によりブラダを介して内周面側からも均一に加熱することが行われている。   During this molding, in order to shorten the vulcanization time and improve productivity, the mold is heated to a predetermined temperature, and the green tire is uniformly heated from the outer peripheral surface side by the mold, and simultaneously heated. Heating is performed uniformly from the inner peripheral surface side through a bladder with a medium.

具体的には、グリーンタイヤを嵌め込むモールド内に電気ヒータを内蔵し、高温度のガスまたはスチームにより膨張させたブラダーでグリーンタイヤの内側を押圧して、グリーンタイヤを内外から加熱するものが知られている。
例えば、上下の型の環状空間にグリーンタイヤを嵌め込み、その内側からブラダーを膨張させて内側から押圧する。その際、上下の型内にはヒータを埋設しておき、他方、上下型内間の空間内に供給されたスチームと窒素ガスを加熱しながら同空間内で循環させて、つまりブラダー内で強制対流をつくり熱伝達を均一化してブラダー内の温度差をなくしグリーンタイヤＴの加硫を均一に行うもの（特許文献１）、 Specifically, an electric heater is built in a mold into which a green tire is fitted, and the inside of the green tire is pressed with a bladder inflated with high-temperature gas or steam to heat the green tire from inside to outside. It has been.
For example, a green tire is fitted into the upper and lower mold annular spaces, and the bladder is inflated from the inside and pressed from the inside. At that time, heaters are buried in the upper and lower molds, and on the other hand, steam and nitrogen gas supplied in the space between the upper and lower molds are circulated in the same space while being heated, that is, forced in the bladder. Convection and uniform heat transfer to eliminate temperature difference in the bladder and vulcanize the green tire T uniformly (Patent Document 1)

また、金型やその周辺部に電磁誘導コイルを配置し、発生する渦電流によるジュール熱を利用してタイヤを加熱し迅速に加硫しようとするもの。即ち、タイヤ加硫装置において、 上側クランプ、下側クランプにグリーンタイヤのビード部分を保持するビードリングを外嵌し、その内部にそれぞれ円筒状のコイルを埋設し、かつ、上部金型及び下部金型の内部に、グリーンタイヤのトレッド部に対応する部分を包囲するように円筒状のコイルを埋設し、これらの各コイルを電流値調整装置等を介して交流電源に接続し、加硫時に、グリーンタイヤのビード及びベルト層の部分に各コイルによる磁界を発生させ誘導加熱するもの（特許文献２）、   In addition, electromagnetic induction coils are placed in the mold and its surroundings, and tires are heated by using Joule heat generated by eddy currents to vulcanize quickly. That is, in a tire vulcanizer, a bead ring that holds a bead portion of a green tire is externally fitted to an upper clamp and a lower clamp, a cylindrical coil is embedded therein, and an upper die and a lower die are embedded therein. A cylindrical coil is embedded inside the mold so as to surround a portion corresponding to the tread portion of the green tire, and each of these coils is connected to an AC power source via a current value adjusting device or the like, and during vulcanization, Inductive heating by generating a magnetic field by each coil in the bead and belt layer of the green tire (Patent Document 2),

同様に、金型やその周辺部に電磁誘導コイルを配置し、電磁誘導加熱により金型内にセットされたグリーンタイヤを加硫成形するようにしたタイヤ加硫装置において、金型にタイヤ周方向に沿って延びる環状の加熱用通路を形成し、その通路内に電磁誘導加熱により加熱可能な液体状の熱媒体、例えばシリコンオイル等を充填して、均一にタイヤを加熱するようにしたもの（特許文献３）、
が知られている。 Similarly, in a tire vulcanizing apparatus in which an electromagnetic induction coil is disposed in the mold and its peripheral portion and a green tire set in the mold is vulcanized by electromagnetic induction heating, the tire circumferential direction is disposed on the mold. An annular heating passage extending along the path is formed, and a liquid heating medium that can be heated by electromagnetic induction heating, for example, silicon oil, is filled in the passage to uniformly heat the tire ( Patent Document 3),
It has been known.

上記タイヤ加硫装置では、金型内部或いはその周辺部に配置された電磁誘導コイルや電気ヒータの温度制御は何れも金型を一体的に加熱することを前提としており、そのため、温度制御を行うにしても金型全体の温度を制御するようになっている。また、メカニカル加硫機やオートクレープについては、ドーム式でセグメントモールド個別のコントロールはできない。   In the tire vulcanizing apparatus, the temperature control of the electromagnetic induction coil and the electric heater disposed inside or around the mold is based on the premise that the mold is integrally heated. Therefore, the temperature control is performed. Even so, the temperature of the entire mold is controlled. In addition, with regard to mechanical vulcanizers and autoclaves, individual segment molds cannot be controlled with a dome type.

ところで、現在のシングル加硫製法では、加硫側にセグメントモールドを保有しており、その構造ではモールド分割数が固定されているため、現在用いられているセグメントモールドを備えた加硫機では、セグメントは同一円周上で等分割して配置されている。   By the way, in the current single vulcanization manufacturing method, the segment mold is held on the vulcanization side, and the number of mold divisions is fixed in the structure, so in the vulcanizer equipped with the currently used segment mold, The segments are equally divided on the same circumference.

このように等分割したセグメントモールドを加熱するものとして、グリーンタイヤの下サイドウォールに当接する下サイドモールド、上サイドウォールに当接する上サイドモールド、及びトレッド部の外周方向に位置する同一円周上に３２に等分割して配置した割りモールド（セグメントモールド）内にそれぞれ電気ヒータを配置し、電気ヒータの熱伝導により各モールドに熱量を供給してグリーンタイヤを加熱し、かつこの３２本のヒータを８本づつ４つのブロックに分け、各ブロック毎に配置された温度センサの検出結果に基づいて各ブロックを別々に温度制御するものも知られている（特許文献４）。   In order to heat the equally divided segment mold, the lower side mold that contacts the lower sidewall of the green tire, the upper side mold that contacts the upper sidewall, and the same circumference located in the outer circumferential direction of the tread portion. Electric heaters are arranged in split molds (segment molds) that are equally divided into 32, and heat is supplied to each mold by heat conduction of the electric heaters to heat the green tires, and the 32 heaters Is also known in which eight blocks are divided into four blocks and the temperature of each block is controlled separately based on the detection result of a temperature sensor arranged for each block (Patent Document 4).

しかしながら、タイヤパターンピッチ数がタイヤ周方向で異なるタイヤを成形するためには、そのピッチ数に応じて異なる分割角度を持ったセグメントモールドが数種類必要である。つまり、そのようなタイヤを成形するには、分割角度の異なるセグメントモールドを用いてグリーンタイヤの成形加工を行う必要がある。   However, in order to form tires having different tire pattern pitch numbers in the tire circumferential direction, several types of segment molds having different division angles depending on the number of pitches are required. That is, in order to form such a tire, it is necessary to form a green tire using segment molds having different division angles.

このようなセグメントモールドを用いる場合、従来の加熱手段で加熱しようとすると、セグメントモールドの分割角度の相違に基く大きさの違いつまり熱容量の違いから、セグメントモールド間で温度差が生じる。そのため、グリーンタイヤに伝導される温度にも差異が生じ、均一な温度による加硫が行われず不良品が発生する虞がある。
この問題は、前記特許文献１から３に記載されたモールド加熱制御では勿論のこと、特許文献４に記載されているように、各セグメントモールド毎にヒータを配置しかつ複数のヒータをブロック毎に制御できるようにしても解決することはできない。 When such a segment mold is used, when it is attempted to heat by a conventional heating means, a temperature difference occurs between the segment molds due to a difference in size based on a difference in segment mold splitting angle, that is, a difference in heat capacity. Therefore, the temperature conducted to the green tire is also different, and there is a risk that vulcanization at a uniform temperature is not performed and a defective product is generated.
This problem is not limited to the mold heating control described in Patent Documents 1 to 3, but, as described in Patent Document 4, a heater is arranged for each segment mold and a plurality of heaters are arranged for each block. Even if it can be controlled, it cannot be solved.

各々のセグメントモールドに加熱手段を設け個別に加熱温度の制御を行うことにより、個々のセグメントモールドの大きさが異なるパターンで温度均一化を行う。 (Function)
Each segment mold is provided with heating means, and the heating temperature is individually controlled, so that the temperature of the individual segment molds is made uniform with different patterns.

本発明を図面に示す実施形態について説明する。
図１は、本発明の実施形態に係るタイヤ製造用熱制御セグメントモールドの側断面図、図２Ａはセクターモールド２０（セグメントモールド２２）と誘導加熱手段２６を拡大して示す図１と同様の図、及び図２Ｂはセクターモールドの一部を省略して示した平面図である。 The present invention will be described with reference to embodiments shown in the drawings.
FIG. 1 is a side sectional view of a thermal control segment mold for manufacturing a tire according to an embodiment of the present invention, and FIG. 2A is an enlarged view of a sector mold 20 (segment mold 22) and induction heating means 26 similar to FIG. FIG. 2B is a plan view in which a part of the sector mold is omitted.

図示のように、このタイヤ加硫用型１０は、タイヤのサイド部を形成する上型１０と下型１４（総称してサイドモールドという）、上型１２を支持する上型プラテン１６、及び上下型１２，１４と共に、内部にグリーンタイヤ（図示せず）を嵌め込む円環状の空間Ｓを形成するセクターモールド２０からなっている。   As shown in the figure, the tire vulcanizing mold 10 includes an upper mold 10 and a lower mold 14 (collectively referred to as side molds) that form tire side portions, an upper mold platen 16 that supports the upper mold 12, and upper and lower molds. Together with the molds 12 and 14, it comprises a sector mold 20 that forms an annular space S into which a green tire (not shown) is fitted.

セクターモールド２０は、円周に沿って複数個、例えば、６〜４０個に分割したセグメントモールド２２の組み合わせから成り、タイヤのトレッド部を形成する。また、その外周面は、図１に示すように上に向かって先細り形状のテーパーが付されていると共に、各セグメントモールド２２は、加熱手段、例えば電磁誘導コイルを備えた誘導加熱手段２６を備えている。各セグメントモールド２２の外周には、そのテーパーに対応したテーパー面を内面に有するアウターリング２４が配置されている。   The sector mold 20 is formed of a combination of a plurality of segment molds 22 divided into, for example, 6 to 40 pieces along the circumference, and forms a tread portion of the tire. Further, as shown in FIG. 1, the outer peripheral surface is tapered in a tapering shape upward, and each segment mold 22 is provided with a heating means, for example, an induction heating means 26 provided with an electromagnetic induction coil. ing. On the outer periphery of each segment mold 22, an outer ring 24 having a tapered surface corresponding to the taper on the inner surface is disposed.

以上の構成において、アウターリング２４を上昇させることで前記各セグメントモールド２２は図１において左側に移動し、続いて、上型プラテン１６及び上型１２を上昇させることで加硫型を開き、逆に、上型プラテン１６を下降させることで上型１２が下降し、アウターリング２４を下降することで、前記各セグメントモールド２２は同図で右方に移動して加硫用型１０を閉じる。   In the above configuration, the segment molds 22 move to the left in FIG. 1 by raising the outer ring 24, and then the vulcanization mold is opened by raising the upper mold platen 16 and the upper mold 12, and vice versa. When the upper mold platen 16 is lowered, the upper mold 12 is lowered, and when the outer ring 24 is lowered, each of the segment molds 22 moves to the right in the figure to close the vulcanizing mold 10.

図２Ｂはセクターモールド２０の一部を示す平面図である。セクターモールドの分割角度は、成形するタイヤパターンのピッチ数に応じてセグメントモールドの分割数で決定されるが、ここでは大、中、小の３種のセグメントモールド２２ａ〜２２ｃが用いられている。加硫時には、この複数のセグメントモールド２２ａ〜２２ｃは、円周状のセクターモールド２０を形成するため密に配置される。各セグメントモールド２２には、加熱手段として例えば誘導コイル２６及び各セグメントモールドの温度を検知するための温度センサー３１（図３参照）が配置されている。この電磁誘導コイルに高周波電流を流すことでセグメントモールド２２を誘導加熱し、その熱でグリーンタイヤ（図示せず）を加熱する。   FIG. 2B is a plan view showing a part of the sector mold 20. The division angle of the sector mold is determined by the number of divisions of the segment mold according to the number of pitches of the tire pattern to be molded. Here, three types of large, medium and small segment molds 22a to 22c are used. At the time of vulcanization, the plurality of segment molds 22 a to 22 c are closely arranged to form a circumferential sector mold 20. Each segment mold 22 is provided with, for example, an induction coil 26 and a temperature sensor 31 (see FIG. 3) for detecting the temperature of each segment mold as heating means. The segment mold 22 is induction-heated by flowing a high-frequency current through the electromagnetic induction coil, and the green tire (not shown) is heated by the heat.

図３は、本実施形態の誘導加熱手段を制御する温度制御装置を概略的に示すブロック図である。
本実施形態の温度制御装置は、図示のように温度センサーを備えた温度測定手段３１と、この温度測定手段３１で測定した温度と予め設定された所定範囲の温度を比較して、測定温度が前記所定範囲内か否かを判断する判定手段３４と、この判定手段３４の判定結果に基づき、つまり、測定温度が所定温度範囲以外であってしかもそれよりも高いときは加熱手段の温度を下げるように、逆に低いときは加熱手段の温度を上昇させるように、加熱手段である誘導コイルの電流を制御する温度補償手段３５と、温度補償手段３５で制御された高周波電流を発生する誘導加熱手段３６とからなっている。ここで、誘導加熱手段３６と温度測定手段３１は、各セグメントモールド２２に配置されており、判定手段３４は、各セグメントモールドの温度に基づき温度の判定を行い、かつ温度補償手段３５は各セグメントモールド２２毎にその温度を調整して温度を前記所定の範囲内に維持するようにする。 FIG. 3 is a block diagram schematically showing a temperature control device for controlling the induction heating means of the present embodiment.
The temperature control device of this embodiment compares the temperature measured by the temperature measuring means 31 with a temperature sensor 31 as shown in the figure and the temperature in a predetermined range set in advance, and the measured temperature is Based on the determination means 34 for determining whether or not it is within the predetermined range and the determination result of the determination means 34, that is, when the measured temperature is outside the predetermined temperature range and higher than that, the temperature of the heating means is lowered. On the contrary, when the temperature is low, the temperature compensation means 35 that controls the current of the induction coil that is the heating means so as to increase the temperature of the heating means, and the induction heating that generates the high-frequency current controlled by the temperature compensation means 35 Means 36. Here, the induction heating means 36 and the temperature measuring means 31 are arranged in each segment mold 22, the determination means 34 determines the temperature based on the temperature of each segment mold, and the temperature compensation means 35 includes each segment mold. The temperature of each mold 22 is adjusted to maintain the temperature within the predetermined range.

本実施形態では、各セグメントモールド２２の温度をその大きさの違いに拘わらず一定範囲に維持できるため、セグメントモールド２２からグリーンタイヤに伝導される熱量にムラが生じることはない。従って、グリーンタイヤを均一な温度で加熱することができる。
また、前記制御装置は、セグメントモールド２２の温度を個別に制御するだけではなく、例えば、グリーンタイヤの温度を検知する温度センサーを設けるなどして、その温度センサーの検知温度に基きセグメントモールド２２を全体として温度制御するようにすることもできる。 In the present embodiment, since the temperature of each segment mold 22 can be maintained within a certain range regardless of the size difference, the amount of heat conducted from the segment mold 22 to the green tire does not vary. Therefore, the green tire can be heated at a uniform temperature.
Further, the control device not only individually controls the temperature of the segment mold 22 but also provides a temperature sensor for detecting the temperature of the green tire, for example, so that the segment mold 22 is controlled based on the detected temperature of the temperature sensor. It is also possible to control the temperature as a whole.

なお、以上の実施形態では、加熱手段として電磁誘導加熱手段を例に採って説明したが、加熱手段はこれに限ることはなく、例えば電気ヒータ、別途加熱手段で加熱された例えばシリコンオイルなどの加熱媒体をセグメントモールドに設けた管路中に流して加熱するものであってもよい。   In the above embodiment, the electromagnetic induction heating means has been described as an example of the heating means. However, the heating means is not limited to this, for example, an electric heater, for example, silicon oil heated by a separate heating means, or the like. The heating medium may be heated by flowing in a pipe line provided in the segment mold.
