Description

本発明にかかるチェーン式搬送装置は、熱処理するワークを搬送するチェーン式搬送装置であって、搬送方向に沿うとともに互いに間隔を隔てて配置された一対のチェーンと、前記一対のチェーン間に架け渡されて前記一対のチェーンとともに循環する複数の架け渡しロッドと、前記架け渡しロッドに前記搬送方向に沿って設けられ前記ワークが載置される複数のアームと、を有し、前記アームは、互いに異なる２本の前記架け渡しロッドに渡って設けられ、前記搬送方向における先行側の回動支持端が一方の前記架け渡しロッドに回動自在に取り付けられ、載置支持端が他方の前記架け渡しロッド上に載置され、前記架け渡しロッドの長手方向に間隔を隔てて配置される２つの前記アームからなるアーム対が、前記搬送方向に複数設けられ、前記アーム対をなす２つの前記アームが、前記回動支持端及び前記載置支持端にて、連結材で連結されていることを特徴とする。 A chain type conveying apparatus according to the present invention is a chain type conveying apparatus that conveys a workpiece to be heat-treated, and a pair of chains that are arranged along the conveying direction and spaced apart from each other, and spans between the pair of chains. A plurality of spanning rods that circulate together with the pair of chains, and a plurality of arms that are provided on the bridging rods along the transport direction and on which the workpiece is placed , the arms being mutually connected Provided over two different spanning rods, a leading rotation support end in the transport direction is pivotally attached to one spanning rod, and a mounting support end is the other spanning bridge A plurality of arm pairs composed of the two arms placed on the rod and spaced apart in the longitudinal direction of the spanning rod are provided in the transport direction. Two of the arms constituting the arm pair at the pivot support end and the placing support edge, characterized in that it is connected by a connecting member.

また、前記アームの前記載置支持端は、前記他方の架け渡しロッドと、前記搬送方向において相対移動可能に載せられていることを特徴とする。 Further, the placement support end prior to said arm, and the other bridged passing the rod, characterized in that it placed movable relative in the transport direction.

また、前記搬送方向において隣り合う２つの前記アーム対は、一方の前記アーム対をなす２つの前記アーム間に、他方の前記アーム対をなす２つの前記アームが配置されることを特徴とする。 Further, the two of the arms adjacent pairs in the transport direction, between two of said arms forming one of said arm pairs, two of said arms being arranged to form the other of said arm pairs.

本発明によれば、ワークを全周から加熱できて、ワークの均一な熱処理が可能であって、機構の熱延び対策も改善することができる。アームは、搬送方向における先行側の回動支持端が架け渡しロッドに回動自在に取り付けられているので、架け渡しロッドに垂れ下がっている状態から、上側に引き上げられるだけで、アームの載置支持端を搬送方向における後方側に位置する架け渡しロッド上に配置することができる。架け渡しロッドの長手方向に間隔を隔てて配置される２つのアームからなるアーム対が、搬送方向に複数設けられ、アーム対をなす２つのアームが、回動支持端及び載置支持端にて、連結材で連結されているので、対をなす２つのアーム、連結材、及び架け渡しロッドが形成する矩形状の部位により、ワークの載置をより安定させることができると共に、例えば、ロボットなどを使用してワークをアーム上に載置する際に、ワークを載置する位置を、一対のアーム、連結材、及び架け渡しロッドが形成する矩形状の部位として認識させることができ、ワークを載置する工程の自動化が容易となる。
According to the present invention, the workpiece can be heated from the entire circumference, the workpiece can be uniformly heat-treated, and the countermeasures against the hot elongation of the mechanism can be improved. The arm has a pivot support end on the leading side in the transport direction that is pivotally attached to the spanning rod. An end can be arrange | positioned on the spanning rod located in the back side in a conveyance direction. A plurality of arm pairs composed of two arms arranged at intervals in the longitudinal direction of the spanning rod are provided in the transport direction, and the two arms forming the arm pair are at the rotation support end and the placement support end. Since it is connected by a connecting material, it is possible to further stabilize the placement of the workpiece by a rectangular portion formed by two arms, a connecting material, and a connecting rod that form a pair. When the workpiece is placed on the arm using the pair of arms, the position where the workpiece is placed can be recognized as a rectangular portion formed by the pair of arms, the connecting material, and the bridge rod. Automation of the mounting process becomes easy.
