部品の関連性を考慮したキッティング•トレーを用いたキッ卜作業を活用した組立作業の訓練方法の考案

摘要

This paper focuses on products such as office machines that involve many manual assembly procedures. A training method in which a trainee assembles and disassembles a product and prepares the parts onto a kitting-tray is proposed. The design of the kitting-tray is based on the relationship between parts. A design step for the kitting-tray, which applies the systematic layout planning method, is presented. A kitting-tray is then made by following the design step. Through experiments where a wooden motorcycle model is assembled, the proposed training method is conpared to a typical training method. From experimental results, it can be seen that the proposed training promotes faster learning than the typical training. Secondly, speed in recollecting work procedures and assembly motions are still retained seven days after training. Finally, the proposed training enhances memorizing of the product structure and retention of the memory.%本研究は，事務機器など手組み付けの多い製品を想定し，部品の組み付け顢序や部品同士の関連性を考慮したキッティング•トレーを用いて，訓練を受ける作業者が組み立てと分解•キット作業をする訓練を提案した.また，S.L.P. (Systematic Layout Planning)法を応用した，部品の関連性を考慮したキッティング•トレーの設計手順を示し，それに基づきキッティング•トレーを作製した.木製バイク模型の組立作業を対象にした実験により，提案する訓練を一般的な訓練と比較した.その結果，提案する訓練は一般的な訓練に比べて，訓練中の習得を早め，訓練から7日後においても動作と作業手頫の想起の早さが維持されるだけでなく，製品の構造に関する記憶が促進•維持されることが確認できた.
