Abstract
Description
まず、実施形態のテープフィーダ1に用いられるキャリアテープ(91、95)の構成について、図1および図2を参考にして説明する。キャリアテープ(91、95)は、複数のキャビティ部(921、961)にそれぞれ部品Pを収納し、これらの部品Pを順番に供給可能とする。キャリアテープ(91、95)は、リールに巻回された形態で提供され、リールから引き出されて用いられる。キャリアテープ(91、95)は、エンボスキャリアテープ91、および定厚キャリアテープ95に大別される。 1. 1. Configuration of Carrier Tape (91, 95) First, the configuration of the carrier tape (91, 95) used in the
次に、実施形態のテープフィーダ1の全体構成について、図3を参考にして説明する。図3の右側は、テープフィーダ1の前側に相当し、図3の左側は、テープフィーダ1の後側に相当する。テープフィーダ1は、幅方向(図3の紙面表裏方向)の厚みが小さな扁平形状に形成されている。テープフィーダ1は、オートローディングフィーダと呼ばれる方式のものである。テープフィーダ1は、複数台が部品装着機に配列されて使用される。テープフィーダ1は、フィーダ本体2、挿入案内部材3、テープ搬送路4、テープ搬送機構7、および制御部8などで構成される。 2. 2. Overall Configuration of
次に、テープ搬送路4の詳細な構成について、図4を参考にして説明を続ける。前述したように、テープ搬送路4は、供給側搬送路5および挿入側搬送路6を含んで構成される。図4において、供給側搬送路5および挿入側搬送路6を形成する手前側の側壁材の一部が省略されている。 3. 3. Detailed Configuration of
次に、オペレータがキャリアテープ(91、95)をテープフィーダ1に挿入したときの作用について、図5および図6を参考にして説明する。加えて、図7および図8の比較例の構成と対比して説明する。 4. Action of
なお、傾斜ガイド63は、実施形態では一つであるが、底部62の幅方向の両方の側縁にそれぞれ設けられて二つとされてもよい。また、実施形態のテープフィーダ1は、オートローディングフィーダであるが、スプライシング作業を行う一般的なテープフィーダであってもよい。ただし、実施形態のテープフィーダ1は、次テープ保持部77を備える構成上の制約から挿入位置61と第四スプロケット74の距離が一般的なテープフィーダよりも大きくなっている。したがって、実施形態のテープフィーダ1において、キャリアテープ(91、95)を挿入する挿入長さが大きくなり、スムーズな挿入を行う効果が顕著となる。本実施形態は、その他にも様々な応用や変形が可能である。 5. Application and Modification of the Embodiment Although the
