図4は、制御部19の制御フロー図である。シガレットフィルター製造装置1を稼働させる際、オペレータは、まず前記操作部を通じて、周速度V1、V2及びV3を仮設定するための情報をシガレットフィルター製造装置1に入力する。このときオペレータは、例えば、シガレットフィルター製造装置1におけるプレテンションロール対7の適切な周速度V0を考慮しながら、シガレットフィルターの仕様に大略的に合うように、周速度V1、V2及びV3を設定するための情報を入力する。
[数1]
RCR(V0)=RCR(plug)×VKDF/V0
制御部19は、数1の周速度V0の値として、制御部19がステップS6を実行する時点の周速度V0の値を用いる。制御部19は、速度計20eで計測した搬出速度VKDFの値を用いる。また、制御部19は、速度計20aより周速度V0を把握する。RCR(plug)は、プラグ残存捲縮である。プラグ残存捲縮RCR(plug)は、トウバンド60の捲縮前におけるプラグ長当たりの重量WT1と、プラグ61中のトウバンド60の重量WT3との比WT3/WT1である。プラグ残存捲縮RCR(plug)は、プラグ61に詰め込まれるトウバンド60に残存する捲縮の程度を示す。第1演算部29aは、トウバンド60のTDとプラグ長Lとにより表される以下の数2に基づいて、重量WT1を算出する。

図5は、第2実施形態に係るシガレットフィルター製造装置100及び制御装置119の側面図である。図5に示すように、シガレットフィルター製造装置100には、外部から制御装置119が接続される。制御装置119は、筐体120の内部に、演算部129と、演算部129と接続され、かつ制御プログラムが格納された記憶部130とを有する。演算部129は、演算部29と同様の構成を有する。演算部129は、第1演算部129a及び第2演算部129bを有する。制御装置119は、ケーブル121を介し、筐体20内の前記駆動部に接続される。シガレットフィルター製造装置100には、速度計20a~20c、20e及び幅検出装置20dが取り付けられる。速度計20a~20c、20e及び幅検出装置20dは、制御装置119に接続される。
図6は、第3実施形態に係る演算装置200の正面図である。図6に示す演算装置200は、シガレットフィルター製造装置用の演算装置である。演算装置200は、トウバンド残存捲縮RCR(V0)及び搬出速度VKDFを指標に用いることにより、シガレットフィルター製造装置の周速度V2とストレッチ比V2/V0とを演算する。
ストレッチ比V2/V0が過大であると、フィラメントが降伏限界点を超えて断裂する。これにより、フライが発生しうる。このフライが多く発生すると、可塑剤添着装置の周囲に蓄積する。このようにフライが蓄積すると、フライが可塑剤を吸収した状態でシガレットフィルターに混入する可能性が高まる。これにより、プラグの内部で可塑剤の濃度が局所的に高くなり、プラグのフィラメントが溶解してメルトホールが発生するおそれがある。
シガレットフィルター製造装置1において、ストレッチ比V2/V0及びリラックス比V3/V2をそれぞれ変化させた場合にシガレットフィルターの物理性能がどのように変化するかを調べた。
なお、本発明は、前述した各実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲で、その構成を変更、追加、又は削除することができる。前記各実施形態は、互いに任意に組み合わせてもよく、例えば1つの実施形態中の一部の構成を他の実施形態に適用してもよい。
