Description
図1は、本実施形態に係る仮撚加工機1の構成を示す模式図である。仮撚加工機1は、糸Yに仮撚加工を施す加工ユニット10(錘とも呼ばれる)が、図1の紙面垂直方向(以下、機台長手方向と言う)に複数並べられた構成となっている。各加工ユニット10は、糸Yを供給する給糸部2と、給糸部2から供給された糸Yに対して仮撚加工を行う加工部3と、加工部3で仮撚加工された糸Yを巻き取ってパッケージPを形成する巻取部4と、を有して構成される。
第1フィードローラ11は、給糸部2から供給された糸Yを第1加熱装置13に向けて送るローラである。第1フィードローラ11は、巻取台6の上部に配置されている。第1フィードローラ11は、駆動ローラ及び従動ローラを有しており、駆動ローラと従動ローラとの間に糸Yを挟んだ状態で糸Yを糸走行方向下流側に送る。各加工ユニット10の駆動ローラは共通の駆動軸に連結されており、一斉に駆動される。第2フィードローラ16、第3フィードローラ18及び第4フィードローラ20も、同様の構成を有する。
図2は、ピン式加撚装置15の構成を示す模式図であり、図3は、ピン式加撚装置15を図2のIII方向から見た図である。ピン式加撚装置15は、円筒状のピン41が軸回りに回転することによって、ピン41の内部を走行する糸Yに撚りを付与するものである。なお、図2において、糸Yは上から下に向かって走行しているものとする。また、図3では、ガイド部材52の図示は省略している。
図4は、仮撚加工機1の電気的構成を示すブロック図である。図4では、紙面の都合上、1つの加工ユニット10についてのみ詳細を図示しているが、他の加工ユニット10も同様の構成である。仮撚加工機1は、複数の加工ユニット10の動作を制御する制御部30を有する。制御部30には、オペレータが制御プログラム及び各種設定値を入力するための設定部31が接続されている。設定部31は、例えばタッチパネルで構成してもよいし、キーボードとモニターの組み合わせ等によって構成してもよい。
以上のように構成された仮撚加工機1において、オペレータが糸生産中にある加工ユニット10の糸Yを切断する場合の一連の流れについて説明する。図5は、糸切断時のフローチャートである。図6は、糸切断時のタイミングチャートである。
本実施形態では、オペレータがスイッチ25(操作部)で減速操作を行うと、ピン41が切断回転数まで減速してから、カッター23によって糸Yが切断される。このため、切断時の糸の撚り数は少なくなり、切断後の糸Yの端に塊が生じるのを抑えることができる。したがって、糸Yの端がピン41を円滑に通過でき、仮撚加工中に糸Yを切断したときにピン41が外れることを抑制することができる。
上記実施形態に種々の変更を加えた変形例について説明する。
