Description
従来の接合装置100は、図示のように、一対の接合ローラ101(図7では、一方の側面を示す)を転動させる。接合ローラ101により、カーカスプライ110の端部同士を接合する。その際、カーカスプライ110の表面では、凸部111が転動する接合ローラ101に強く押し付けられる。これにより、カーカスプライ110が、一対の接合ローラ101に巻き込まれることがある。カーカスプライ110が、一対の接合ローラ101の間に噛み込まれる虞もある。
また、本発明は、ゴムで形成されたタイヤ構成部材の端部同士を接合して、接合されたタイヤ構成部材を製造するタイヤ構成部材の製造方法であって、一対の接合ローラの移動方向前方のタイヤ構成部材の両端部を、一対の接合ローラの外周に沿って押さえて、両端部の一対の接合ローラへの巻き込みを防止する工程と、一対の接合ローラを、タイヤ構成部材の対向する各端部上を転動させて、端部同士を突き合わせて接合する工程と、を有することを特徴とする。
タイヤ構成部材は、タイヤ各部を構成する部材である。本実施形態の接合装置は、ゴムで形成されたタイヤ構成部材の端部同士を突き合わせて接合する。これにより、端部が接合されたタイヤ構成部材(接合タイヤ構成部材)を製造する。
接合装置1は、図示のように、成形ドラム2と、タイヤ構成部材90を接合する一対の接合ユニット30とを備えている。一対の接合ユニット30は、成形ドラム2の軸線方向に並べて配置されている。接合装置1は、成形ドラム2の外周面に沿って配置された移動手段(移動機構)10を備えている。移動手段10は、一対の接合ユニット30を成形ドラム2の軸線方向及び半径方向(図1では左右方向及び上下方向)に移動させる。移動手段10は、成形ドラム2の上方に配置されている。
接合ユニット30は、図示のように、一対の接合ローラ40(40A、40B)と、巻込防止部材70と、押さえローラ32と、補強ローラ50とを有する。一対の接合ローラ40は、接合ユニット30に少なくとも1組み設けられる。巻込防止部材70は、タイヤ構成部材90が一対の接合ローラ40に巻き込まれるのを防止する。
接合ローラ40には、図示のように、突条Tが形成されている。突条Tは、接合ローラ40の周方向に延びる環状(又は螺旋状)に形成される。突条Tは、接合ローラ40の外周に複数並列して形成される。接合ローラ40の断面形状は、複数の突出部が並んだ鋸歯状に形成される。この突条Tでは、突起41側の側面が接合ローラ40の軸線方向と直交し、他方側の側面が所定角度で傾斜する。突条Tは、断面三角形状に形成され、突起41を含む接合ローラ40の外周の全体に配置される。突条Tは、タイヤ構成部材90の端部91、92に押し付けられる。接合ローラ40は、突条Tにより、端部91、92の所定範囲を押圧する。
図示のように、タイヤ構成部材90は、複数の有機繊維コードCを有する。端部91、92の接合により、表面側(図4では上側)のゴム93Wが、突起41A、41Bにより部分的に引き伸ばされる。ゴム93Wは、交互に端部91、92の表面まで引き伸ばされる。接合部93は、内側(図4では下側)では直線的に圧着される。これに対し、接合部93は、表面側では波状をなして接合される。表面側の端部91、92は、交互に相手側の表面に重なり合う。
図5は、接合ユニット30の要部を示す側面図である。図5では、接合ユニット30を図2の矢印Z方向から見て示している。図5に示す接合ユニット30は、ローラ32、40、50がタイヤ構成部材90から離間した状態にある。
巻込防止部材70は、上記したように、一対の接合ローラ40の移動方向Sの前方近傍で、タイヤ構成部材90の両端部91、92を押さえる押さえ部72を有する。巻込防止部材70は、押さえ部72により、接合ローラ40が接合するタイヤ構成部材90の両端部91、92を、接合ローラ40に接触する前に押さえる。巻込防止部材70は、端部91、92の浮き上がりや表面の凸部95を押さえて端部91、92を均す。巻込防止部材70は、両端部91、92を比較的平坦な状態で一対の接合ローラ40に接触させる。
