Description
本発明は、上記の課題に鑑みてなされたものであり、簡易な構成により生タイヤの内側から放射熱を用いて生タイヤを加熱可能なタイヤ加硫装置を提供することを目的とする。
上記態様のタイヤ加硫装置は、センターポストに加熱部が固定される構成であるので、簡易な構成により生タイヤの内側から放射熱を用いて生タイヤを加熱可能である。
この場合、遮蔽部における開閉状態に応じて、生タイヤの内面にヒータからの熱が伝達される状態と、生タイヤの内面にヒータからの熱が伝達されない状態とに切替可能である。
この場合、遮蔽部材がヒータを囲む遮蔽位置にあるときには、ヒータの熱は遮蔽部材に遮られて生タイヤに到達しない。また、遮蔽部材を移動機構が移動させることによって、遮蔽部における開閉状態が変化する。
この場合、格納状態ではヒータが小型であり、発熱時状態において遮蔽部材外にヒータが位置している時にはヒータ部材同士の重なりが少なく放射熱を発することが可能な面積を広く確保することができる。
この場合、加熱部はブラダを介して生タイヤを加熱する。
この場合、ドライガスはブラダ内で液化せずに気体状態であるので、ブラダ内の温度が均一になりやすい。
この場合、加熱部によるブラダの加熱により水蒸気が液化しにくくなるので、ブラダ内の温度が均一になりやすい。
