Abstract
Description
近年、製函機においても高速化が進んでおり、カウンタエゼクタにおいても処理速度の向上が求められており、このような観点からカウンタエゼクタに関する種々の技術が提案されている。
スパンカ111の下部には、一方の補助レッジ122aがホッパ部Hに出入り可能に取り付けられている。この補助レッジ122aの下方には、スタック150を押し出すプッシャ124が出入り可能に設けられている。フロントストップ126の下部には、もう一つの補助レッジ122bがホッパ部Hに出入り可能に設けられ、両補助レッジ122a,122bは互いに対向して配置され、後述のレッジ136上のスタック150を受ける。
つまり、機械の高速化を進めていくためには、図11(a)に示すように、送り出しロール102の出口付近の上方に配置されたブロアから下向きに加えるエア圧APを高めて段ボール箱103をより速く下降させることが必要になる。
こうした不具合は、搬送方向のサイズの小さい段ボール箱の場合は発生しないが、搬送方向のサイズの大きい段ボール箱の場合に発生することも判明した。
前記制御装置は、前記段ボール箱の前記搬送方向のサイズに応じて前記搬送方向への前記送風領域又は前記風量を変更操作することが好ましい。
前記送風装置は、さらに前記段ボール箱の幅方向への送風領域を可変とするものであって、前記制御装置は、前記段ボール箱の前記搬送方向のサイズ及び前記幅方向のサイズの少なくともいずれかに応じて前記搬送方向への前記送風領域又は前記風量を変更操作することが好ましい。
前記制御装置は、前記段ボール箱の材質、坪量、フルートに応じて前記送風領域又は前記風量を変更操作することが好ましい。
前記送風装置は、前記ホッパ部における前記搬送方向の後端部に対応した位置に固定された固定送風装置と、前記ホッパ部における前記搬送方向の前端部において前記段ボール箱の前記搬送方向のサイズに応じて可動な可動送風装置とを有していることが好ましい。
前記送風装置は、前記搬送方向又は前記段ボール箱の幅方向に並べられそれぞれ個別に運転操作可能な複数の送風ファンを備え、前記複数の送風ファンを選択的に作動させることによって送風領域を可変とすることが好ましい。
特に、段ボール箱の搬送方向のサイズに応じて搬送方向への送風領域又は風量を変更操作すれば、ホッパ部へ向けて下降する際の段ボール箱の姿勢や挙動を搬送方向のサイズに応じて適正化することができ、段ボール箱の幅方向のサイズ等に応じて搬送方向への送風領域又は風量を変更操作すれば、ホッパ部へ向けて下降する際の段ボール箱の姿勢や挙動を幅方向のサイズに応じて適正化することができる。
製函機の運転速度に応じて送風領域や風量を変更操作すれば、ホッパ部へ向けて下降する際の段ボール箱の姿勢や挙動を適正化しながら、運転速度を高速化することができる。
送風装置として、搬送方向の後端部に固定した固定送風装置と、搬送方向の前端部に段ボール箱の搬送方向のサイズに応じて可動な可動送風装置とを備えれば、常に段ボール箱の搬送方向の前端部と後端部との両方に送風することができ、段ボール箱の搬送方向に関する姿勢や挙動の変化を矯正することが可能になる。
送風装置が、段ボール箱の搬送方向や幅方向に並べられそれぞれ個別に運転操作可能な複数の送風ファンを備え、これらの複数の送風ファンを選択的に作動させることによって送風領域を可変としても、送風領域の変更を容易に行なうことができる。

図1(a),図1(b)~図7(a)~図7(c)は本発明の第1実施形態にかかるカウンタエゼクタを説明するものであり、図8(a),図8(b)は本発明の第2実施形態にかかるカウンタエゼクタを説明するものであり、図9(a),図9(b)は本発明の第3実施形態にかかるカウンタエゼクタを説明するものである。また、図2,図3は第1実施形態だけでなく、第2,3実施形態にも流用する。
まず、本発明の第1実施形態にかかるカウンタエゼクタを備える製函機の構成を説明する。
図2では、段ボールシートがシート状の段ボール箱(製函用シート材)に加工される過程を、製函機の各工程の装置構成の上方に、装置構成とは分けて装置構成に対応させて付記している。図2に示すように、この製函機は、上流側から、給紙部1,印刷部2,排紙部3,ダイカット部4,フォルダグルア部5,カウンタエゼクタ部6が設けられている。
次に、図3を参照して、カウンタエゼクタ部(即ち、本実施形態に係るカウンタエゼクタ)6について説明する。
スパンカ23の下部には、一方の補助レッジ25aがエアシリンダ26によりホッパ部Hに出入り可能に取り付けられている。この補助レッジ25aの下方には、スタック50を押し出すプッシャ27が図示しないエアシリンダ等のアクチュエータにより出入り可能に設けられている。
図1(a),図1(b)に示すように、両サイドフレーム36に支持された梁36aには、製函用シート材10の幅方向に並んだ複数(ここでは、3個)の固定ファン52が固定されており、フロントストップ28に支持された梁28aには、製函用シート材10の幅方向に並んだ複数(ここでは、2個)の可動ファン53が固定されている。したがって、固定ファン52は、ホッパ部Hにおける搬送方向の後端部に対応した位置に配置され、可動ファン53は、ホッパ部Hにおける搬送方向の前端部に対応した位置に配置される。
図5(c)に示すように、バッチ100が下部コンベア47及び排出コンベア48等により移動を開始すると、プレスバー44がわずかに上昇し当該バッチ100の上面から離れる。そして、レッジ42はプレスバー44と一緒に、次の上昇に備えてスタック50aと干渉しない位置まで後退する。この時、レッジ42上のスタック50aは、補助レッジ25a,25bが受けている。この過程の間にバッチ100はエレベータ32から完全に離れる。
例えば、図7(a)に示すように、搬送方向サイズの大きい製函用シート材10の場合、搬送方向の後端部の固定ファン52による空気流AF1に加えて、搬送方向の前端部の可動ファン53を作動させて可動ファン53による空気流AF2を作用させれば、搬送方向の後端部の固定ファン52による空気流AF1の強さを抑えながら、製函用シート材10全体には、十分な空気流(AF1+AF2)を作用させるので、過剰に強い空気流AF1による製函用シート材10の不適正な姿勢や挙動を発生させることなく、図7(b)に示すように、製函用シート材10を速やかに降下させることができる。
さらに、通常、製函用シート材10は、段の延びる方向(段方向)を搬送方向と一致させて搬送されるが、特殊な製函用シート材10の場合、段方向を搬送方向と直交する向きにして搬送される場合があるが、この場合、製函用シート材10の搬送方向への変形が大きくなり易く、より綿密な送風領域や風量の設定が望まれるが、ファン52,53の数を増やすなどして対応することで、かかる対応も可能となる。
次に、図8(a),図8(b)を参照して、本発明の第2実施形態にかかるカウンタエゼクタを説明する。なお、図8(a),図8(b)において記述の符号と同様のものは同様の部材を示し、説明は省略する。
本実施形態は、送風装置のみが第1実施形態と異なっている。
このような構成でも、第1実施形態と同様に、製函用シート材10の姿勢や挙動を適正に保持しながら、製函用シート材10を速やかにホッパ部Hへ下降させることができ、これにより、製函機の高速化を促進することができる。
また、本実施形態の場合、マトリクス状に配置された多数の固定ファン55により綿密な送風領域や風量の設定が可能になる。
次に、図9(a),図9(b)を参照して、本発明の第3実施形態にかかるカウンタエゼクタを説明する。なお、図9(a),図9(b)において記述の符号と同様のものは同様の部材を示し、説明は省略する。
本実施形態は、送風装置のみが第1,2実施形態と異なっている。
さらに、送風用ダクト59の出口部には、幅方向に延在する多数の開閉シャッタ62が並設され、これらも個々に開閉操作されるようになっている。
このような構成でも、第1,2実施形態と同様に、製函用シート材10の姿勢や挙動を適正に保持しながら、製函用シート材10を速やかにホッパ部Hへ下降させることができ、これにより、製函機の高速化を促進することができる。
以上、本発明の実施形態について説明したが、本発明は上述の各実施形態のものに限定されず、本発明の趣旨を逸脱しない範囲で、適宜変形或いは省略或いは組み合わせをして実施することができる。
もちろん、上述の各実施形態に例示するカウンタエゼクタや製函機の各部の具体的な構成も一例であり、これらの構成についても本発明の趣旨を逸脱しない範囲で変形することができる。
