【発明の属する技術分野】
この発明は、ビードフィラーの圧着方法及びその装置に係わり、更に詳しくは円環状のビードワイヤーの外周面上にビードフィラーを圧着させて貼付け後にビードフィラーの剥離の確認作業や修正作業を不要とし、ビードフィラーの接合部（スプライス部）の故障を減少させることが出来るビードフィラーの圧着方法及びその装置に関するものである。
【０００２】
【従来の技術】
従来、ラジアルタイヤの成形において、円環状に成形されたビードワイヤーの外周面上にビードフィラーと一般に呼称される断面略三角形状の比較的硬度の高いゴム部材を配置することが行われている。
【０００３】
そして、その成形方法としては、回転自在に保持された円環状のビードワイヤーの外周面上に、ゴム押出機から断面略三角形状のビードフィラーを押出し、ビードワイヤーの周長に対応させた長さに切断した後、圧着させていた。
【０００４】
【発明が解決しようとする課題】
そのため、幅のあるビードフィラーの底面をビードワイヤー上に載置させ、その端末部をスプライスさせることになり、その結果、ビードフィラーの外周側のスプライス部分が剥がれ易いと言う問題があった。従って、スプライス作業終了後、所定時間経過時に作業員によるスプライス部の剥がれ確認作業や、剥がれた部分の修正作業は不可欠であった。
【０００５】
そこで、発明者等がスプライス作業の状況を詳細に、かつ鋭意検討した結果、従来は先ずビードワイヤー上にビードフィラーの底面部を圧着してからスプライス部を、ビードワイヤー側から順にビードフィラーの外周側に向かって圧着していくため結果的にビードフィラーの外周側が伸ばされてから圧着されていることが明らかとなった。
【０００６】
即ち、従来のビードフィラー成形方法では、ビードフィラーの内周側と外周側の周長差による不必要な張力がビードフィラーの最も薄い外周側に集中するため、その部分のスプライスが剥がれ易かったのである。
【０００７】
この発明の目的は、ビードワイヤーの外周面にビードフィラーの貼付け，圧着作業終了後における剥がれ等の不具合を減少させ、作業終了後の剥がれ確認作業や修正作業を不要にし、タイヤ加硫工程で発生していたビードフィラー接合部分の故障を著しく減少させることが出来るビードフィラーの圧着方法及びその装置を提供することにある。
【０００８】
【課題を解決するための手段】
この発明は上記目的を達成するため、この発明のビードフィラーの圧着方法は、押出し成形されたビードフィラーの両端末部近傍を左右一対の把持爪により保持し、該ビードフィラーの両端末部を引き寄せて接合させた後、該ビードフィラーを左右一対の把持爪により保持した状態でビードフィラーの底面部をビードワイヤーの外周面上に圧着することを要旨とするものである。
【０００９】
また、この発明のビードフィラーの圧着装置は、円環状に形成されたビードワイヤーを回転可能に支持するビードワイヤー保持装置と、ビードフィラーの端末部を貼合わせた状態でビードワイヤー上に圧着させる圧着貼付け装置とからなり、前記圧着貼付け装置は、ビードワイヤー保持装置の外周部近傍に、ビードフィラーの両端末部近傍を把持する左右一対の把持爪と、該把持爪を接近・離反させる接合手段と、両端末部が貼合わされたビードフィラーを左右一対の把持爪により保持した状態で、把持爪を介してビードフィラーの底面部をビードワイヤーの外周面上に圧着する圧着手段とで構成したことを要旨とするものである。
【００１０】
この発明は、上記のように構成され、押出し成形されたビードフィラーの両端末部近傍を左右一対の把持爪により保持し、該ビードフィラーの両端末部を引き寄せて接合させた後、該ビードフィラーを左右一対の把持爪により保持した状態でビードフィラーの底面部をビードワイヤーの外周面上に圧着するので、スプライス作業終了後におけるビードフィラーの剥がれ状況を作業員が確認したり、修正作業を行う必要が少なく、またタイヤ加硫工程で発生していたビードフィラー接合部分の故障を著しく減少させることが出来るものである。
【００１１】
【発明の実施の形態】
以下、添付図面に基づき、この発明の実施形態を説明する。
【００１２】
図１は、この発明のビードフィラーの圧着方法を実施するための圧着装置の概略正面図、図２は図１のＡ−Ａ矢視側面図、図３は図１のＢ−Ｂ矢視側面図を示し、この圧着装置は、円環状に形成されたラジアルタイヤのビードワイヤーＷを回転可能に支持するビードワイヤー保持装置１と、図示しない押出機から押出された断面略三角形状のビードフィラーＦの両端末部を貼合わせた状態でビードワイヤーＷ上に圧着させる圧着貼付け装置２とから構成されている。
【００１３】
前記ビードワイヤー保持装置１は、ビードワイヤーＷを回転自在に支持する複数本のガイドローラ３ａ，３ｂと、駆動ローラ４等から構成され、また前記圧着貼付け装置２は、図２及び図３に示すように、ビードワイヤー保持装置１の外周部近傍に、ビードフィラーＦの両端末部近傍を把持シリンダー等の把持手段５，６を介して把持する左右一対の把持爪５ａ，５ｂ、６ａ，６ｂと、該把持爪５ａ，５ｂ、６ａ，６ｂをそれぞれ接近・離反させる把持シリンダー等の接合手段７ａ，７ｂと、両端末部が接合わされたビードフィラーＦを左右一対の把持爪５ａ，５ｂ、６ａ，６ｂで保持した状態で、該ビードフィラーＦの底面部を、前記ビードワイヤーＷの外周面上に圧着する圧着シリンダー等の圧着手段８とで構成されている。
【００１４】
前記左右一対の把持爪５ａ，５ｂ、６ａ，６ｂは、接合手段７ａ，７ｂのフレームの先端にボルト等の取付け金具を介して着脱可能に取付けられ、左右一対の把持爪５ａ，５ｂ、６ａ，６ｂの把持側内面には、ビードフィラーＦのプロファイル（略三角形状）に対応した保持溝９ａ，９ｂが形成されている。
【００１５】
なお、図１において１０は圧着ローラ、１１はビードフィラーＦをビードワイヤーＷの周長に対応させて切断する切断カッター、１２は把持爪５ａ，５ｂ、６ａ，６ｂのストッパーピンを示している。
【００１６】
次に、上記のような構成から成る圧着装置を用いてビードフィラーの圧着方法を説明する。
【００１７】
先ず、円環状に形成されたビードワイヤーＷをビードワイヤー保持装置１のガイドローラ３ａ，３ｂと駆動ローラ４とに掛回し、ビードワイヤーＷを一定の速度で回転させながらビードワイヤーＷの外周面上に、押出機から押し出された断面略三角形状のビードフィラーＦを順次貼付けていき、ビードワイヤーＷの周長に対応する長さで切断カッター１１により切断する。
【００１８】
そして、ビードフィラーＦの両端末部を、図４及び図５（ａ）に示すように左右一対の把持爪５ａ，５ｂ、６ａ，６ｂにより把持し、把持シリンダー等の接合手段７ａ，７ｂでビードフィラーＦの両端末部を図５（ｂ）に示すように引き寄せて接合させた後、図５（ｃ）に示すように左右一対の把持爪５ａ，５ｂ、６ａ，６ｂにより把持したビードフィラーＦの底面部を圧着シリンダー等の圧着手段８でビードワイヤーＷの外周面上に圧着する。
【００１９】
圧着した後は、左右一対の把持爪５ａ，５ｂ、６ａ，６ｂがビードフィラーＦの両端末部を開放し、圧着手段８で把持爪５ａ，５ｂ、６ａ，６ｂを上昇させて圧着方法は完了する。
【００２０】
このように、この発明ではビードフィラーＦの端末部同士を接合させた後、ビードワイヤーＷの外周面上に圧着させるので、不必要な張力がビードフィラーＦの最も肉厚の厚い内周側に分散して作用するため、接合作業終了後の剥がれ等の不具合が極めてすくなくなり、接合部における故障も著しく減少させることが出来た。
【００２１】
即ち、従来のビードフィラーの成形方法では、ビードフィラーの内周側と外周側の周長差による不必要な張力がビードフィラーの最も薄い外周側に集中するため、その部分のスプライスが剥がれ易いと言う問題があったが、この点をこの発明では有効に解決することが出来たのである。
【００２２】
【発明の効果】
この発明は、上記のように円環状に形成されたビードワイヤーを回転可能に支持するビードワイヤー保持装置と、ビードフィラーの端末部を貼合わせた状態でビードワイヤー上に圧着させる圧着貼付け装置とからなり、前記圧着貼付け装置は、ビードワイヤー保持装置の外周部近傍に、ビードフィラーの両端末部近傍を把持する左右一対の把持爪と、該把持爪を接近・離反させる接合手段と、両端末部が貼合わされたビードフィラーを左右一対の把持爪により保持した状態で、把持爪を介してビードフィラーの底面部をビードワイヤーの外周面上に圧着する圧着手段とで構成し、押出し成形されたビードフィラーの両端末部近傍を左右一対の把持爪により保持し、該ビードフィラーの両端末部を引き寄せて接合させた後、該ビードフィラーを左右一対の把持爪により保持した状態でビードフィラーの底面部をビードワイヤーの外周面上に圧着するので、ビードワイヤーの外周面にビードフィラーの貼付け，圧着作業終了後における剥がれ等の不具合を減少させることが出来、作業終了後の剥がれ確認作業や修正作業を不要にでき、またタイヤ加硫工程で発生していたビードフィラー接合部分の故障を著しく減少させることが出来る効果がある。

The present invention relates to a method and an apparatus for crimping a bead filler that can reduce the failure of a joint portion (splice portion) of the bead filler.
[0002]
[Prior art]
Conventionally, in the formation of a radial tire, a relatively hard rubber member having a generally triangular cross-section generally called a bead filler has been disposed on the outer peripheral surface of a bead wire formed in an annular shape.
[0003]
And as the molding method, on the outer peripheral surface of the annular bead wire that is rotatably held, a bead filler having a substantially triangular cross section is extruded from a rubber extruder, and the length corresponds to the peripheral length of the bead wire. After being cut into pieces, they were crimped.
[0004]
[Problems to be solved by the invention]
For this reason, the bottom surface of the wide bead filler is placed on the bead wire, and the end portion thereof is spliced. As a result, there is a problem that the splice portion on the outer peripheral side of the bead filler is easily peeled off. Therefore, after completion of the splicing work, it is indispensable for the worker to check the peeling of the splice part and to correct the peeled part when a predetermined time has elapsed.
[0005]
Therefore, as a result of detailed studies by the inventors in detail and the splicing work, conventionally, the bottom of the bead filler is first crimped on the bead wire, and then the splice portion is arranged in order from the bead wire side to the outer periphery of the bead filler. As a result, it was clarified that the outer peripheral side of the bead filler was stretched and then crimped.
[0006]
That is, in the conventional bead filler molding method, unnecessary tension due to the difference in circumference between the inner and outer peripheral sides of the bead filler is concentrated on the thinnest outer peripheral side of the bead filler, so the splice at that portion was easily peeled off. is there.
[0007]
The purpose of this invention is to reduce problems such as sticking of bead filler to the outer peripheral surface of the bead wire and peeling after completion of the crimping work, eliminating the need for peeling confirmation work and correction work after the work is finished, and occurring in the tire vulcanization process It is an object of the present invention to provide a method and an apparatus for crimping a bead filler that can significantly reduce the failure of the bead filler joint portion.

And then bonding the bottom surface of the bead filler onto the outer peripheral surface of the bead wire in a state where the bead filler is held by a pair of left and right gripping claws .
[0009]
In addition, the bead filler crimping device of the present invention is a crimping method in which a bead wire holding device for rotatably supporting a bead wire formed in an annular shape and a bead wire are crimped on a bead wire in a state where the end portions of the bead filler are bonded together. The pressure bonding apparatus includes a pair of left and right gripping claws for gripping the vicinity of both end portions of the bead filler, and a joining means for approaching and separating the gripping claws in the vicinity of the outer periphery of the bead wire holding device. In the state where the bead filler bonded to both end portions is held by a pair of left and right gripping claws, the bottom portion of the bead filler is configured to be crimped onto the outer peripheral surface of the bead wire via the gripping claws. It is a summary.
[0010]
The present invention is configured as described above, and the vicinity of both end portions of the extruded bead filler is held by a pair of left and right gripping claws, and the both end portions of the bead filler are pulled and joined together, and then the bead filler Since the bottom of the bead filler is crimped onto the outer peripheral surface of the bead wire while being held by a pair of left and right gripping claws , the worker confirms the peeling condition of the bead filler after the completion of the splicing work or performs correction work. It is less necessary and can significantly reduce the failure of the bead filler joint portion that has occurred in the tire vulcanization process.
[0011]
DETAILED DESCRIPTION OF THE INVENTION

[0013]
The bead wire holding device 1 includes a plurality of guide rollers 3a and 3b that rotatably support the bead wire W, a driving roller 4, and the like, and the pressure bonding device 2 is shown in FIGS. As described above, a pair of left and right gripping claws 5a, 5b, 6a, 6b for gripping the vicinity of both end portions of the bead filler F via gripping means 5 and 6 such as gripping cylinders, in the vicinity of the outer periphery of the bead wire holding device 1 The gripping claws 5a, 5b, 6a, and 6b are joined and separated from each other by a joining means 7a and 7b such as a gripping cylinder, and a bead filler F joined at both ends to a pair of left and right gripping claws 5a, 5b, 6a, It is comprised with the crimping | compression-bonding means 8, such as a crimping cylinder which crimps | bonds the bottom face part of this bead filler F on the outer peripheral surface of the said bead wire W in the state hold | maintained by 6b.
[0014]
The pair of left and right gripping claws 5a, 5b, 6a, 6b are detachably attached to the ends of the frames of the joining means 7a, 7b via mounting brackets such as bolts, and the pair of left and right gripping claws 5a, 5b, 6a, Holding grooves 9a and 9b corresponding to the profile (substantially triangular shape) of the bead filler F are formed on the inner surface of the grip 6b.
[0015]
In FIG. 1, reference numeral 10 denotes a pressure roller, 11 denotes a cutting cutter that cuts the bead filler F in accordance with the circumference of the bead wire W, and 12 denotes stopper pins of the gripping claws 5a, 5b, 6a, and 6b.
[0016]
Next, a method for crimping the bead filler using the crimping apparatus having the above configuration will be described.
[0017]
First, the bead wire W formed in an annular shape is hung on the guide rollers 3a and 3b and the drive roller 4 of the bead wire holding device 1, and the bead wire W is rotated at a constant speed on the outer peripheral surface of the bead wire W. Next, the bead filler F having a substantially triangular cross-section extruded from the extruder is sequentially pasted and cut by the cutting cutter 11 at a length corresponding to the circumference of the bead wire W.
