【課題を解決するための手段】
上記目的を達成するため、本発明に係る加熱炉は、炉体と、上記炉体の内部温度を高める加熱手段と、複数の被加熱体を連続的に炉体の内部に通過させるコンベアラインとを備えてなる加熱炉において、上記コンベアラインに搬送されて炉体の内部を通過する上記被加熱体を途中で一旦炉体外部に搬出し、再度炉体内部に搬入する中間取出部を少なくとも一箇所構成したことを特徴とする。
また、本発明に係る加熱炉は、一基の炉体にコンベアラインの出入口を設け、この出入口から炉体の外部に出て再び炉体の内部に入るコンベアラインのＵターン部を前記中間取出部としたことを特徴とする。
さらに、本発明に係る加熱炉は、複数の炉体を直列的に配置し、各炉体の間に中間取出部を構成したことを特徴とする。[0011]
[Means for solving problems]
In order to achieve the above object, the heating furnace according to the present invention includes a furnace body, a heating means for raising the internal temperature of the furnace body, and a conveyor line for continuously passing a plurality of heated bodies into the inside of the furnace body. In the heating furnace provided with the above, at least one intermediate take-out part is provided, in which the heated body, which is conveyed to the conveyor line and passes through the inside of the furnace body, is once carried out of the furnace body on the way and then carried into the inside of the furnace body again. It is characterized by having a location.
Further, in the heating furnace according to the present invention, a conveyor line entrance / exit is provided in one furnace body, and the U-turn portion of the conveyor line that goes out of the furnace body from this entrance / exit and enters the inside of the furnace body again is taken out in the middle. It is characterized by being a part.
Further, the heating furnace according to the present invention is characterized in that a plurality of furnace bodies are arranged in series and an intermediate take-out portion is formed between the furnace bodies .

ところで、本実施形態において第一出入口２と第二出入口３は個別の開口部として形成されているが、一つの開口部としてまとめてもよい。また、コンベアライン１１は炉体１内において第一Ｕターン部１１ａおよび第三Ｕターン部１１ｃ以外では直線状に配設されているが、非直線状に配設してもよい。さらに、中間取出部１７をより多く設置し、より複雑な塗装工程等に対処させてもよい。
なお、二基以上の加熱炉を直列的に配置しても、各加熱炉の中間部において塗装部品をコンベアラインから取り外すことなくマスキングテープを剥がすといった作業を行うことができる。 [0027]
By the way, although the first doorway 2 and the second doorway 3 are formed as separate openings in the present embodiment, they may be combined as one opening. Further, although the conveyor line 11 is arranged linearly in the furnace body 1 except for the first U-turn portion 11a and the third U-turn portion 11c, it may be arranged non-linearly. Further, more intermediate take-out portions 17 may be installed to cope with a more complicated painting process or the like.
Even if two or more heating furnaces are arranged in series, it is possible to remove the masking tape at the intermediate portion of each heating furnace without removing the painted parts from the conveyor line.
