Abstract
Description
缶胴部の加飾としては、印刷が施されたり、特許文献1のようにエンボスが施されるものがある。一方、缶肩部の加飾として、特許文献2のように印刷が施されるものや、特許文献3~5のように肩部に凹凸模様が施されるものがある。
まず、図1,2を用いて、第一実施形態の缶1を説明する。
缶1の胴部2下端側(底部側)には、下方に向かうにつれ漸次縮径されるチャイム部6を備える。
口部4の内径φAは、例えば、25~60mmにすることができる。
また、肩部3の最大外径φB(つまり、肩部3と胴部2の接続部分の外径であって、胴部2の側面がストレート状になっている場合には、胴部2の外径と同じになる)は、例えば、50~70mmにすることができる。
陥没した凹部とは、缶外面から見て凹状、かつ、缶内面から見て凸状の立体形状のことである。隆起した凸部とは、缶外面から見て凸状、かつ、缶内面から見て凹状の立体形状のことである。
なお、図2(b)の例では、立体形成部は、肩部高さ方向に沿った列が、周方向に複数配列されている。複数の列には、同形の複数の陥没した凹部が異なる個数(例えば1~4個)並べられている。これにより、肩部3の周方向で立体形成部の形が異なっている。
なお、肩部3は、縮径加工されるので、肩部3の肉厚は、胴部2等の肉厚よりも、厚くてもよい。この場合には、肩部3は、十分な強度を有するので、加工時におけるピンホール等の形成をさらに抑制でき、また、外力に起因する座屈等を抑制できる。
なお、傾斜角度θは、肩部3を胴部2側に延長した面と、胴部2とのなす角である。
これにより、図3等に示すような、缶1の中間成形体である缶1Pが製造される。
なお、インナーロール11の受け部11aは、缶1の肩部3の形状に応じて、凹及び凸の少なくとも1つを備えていればよい。すなわち、肩部3が隆起した凸部を有する場合には、受け部11aは、凸を備えていればよい。肩部3が陥没した凹部及び隆起した凸部を有している場合には、受け部11aは、凸及び凹を備えていればよい。アウターロール12の凸、凹についても、同様である。
また、缶1P及びインナーロール11の受け部11aの両方が一定の傾斜角の円錐台状側面部分を備えている。このような円錐台状側面部分は、球面状(縦断面外方に向けて凸の曲率半径を持つ形状)の側面部分に比べ、インナーロール11、アウターロール12からの加工力が肩部3Pに伝わりやすいので、より好適である。
なお、シャフト11bを受け部11a側に延長した面と、受け部11aの側面とがなす角θは、前述した肩部3を胴部2側に延長した面と、胴部2とがなす角と同じ角度である。
なお、図示は省略するが、インナーロール11、アウターロール12は、立体形成部加工装置10の回転駆動装置(回転部)によって、回転される。
缶1Pを、図示しない搬送装置により載置台13に載置する。
次に、載置台13を移動させることにより、缶1Pを加工位置まで移動する。
これにより、インナーロール11を、口部4から缶1Pの内部に挿入にする。
インナーロール11及びアウターロール12を、缶1Pの肩部3Pに相対的に接近することにより、受け部11a及びアウターロール12で肩部3Pを挟み込む。すなわち、受け部11aは、肩部3Pを内側から受け、一方、アウターロール12は、肩部3Pを外側から押圧する。
また、後述のロール退避工程において、インナーロール11とアウターロール12とを肩部3から離す際も、立体形成部の凹部の陥没方向、又は凸部の隆起方向によっては、その方向に沿って移動させてもよい。
挟み込み工程によって受け部11a及びアウターロール12で肩部3Pを挟み込んだ状態で、インナーロール11及びアウターロール12を回転させ、また、載置台13及び缶1Pを一体で回転する。そして、缶1Pが所定量(例えば1回転以上)回転することにより、立体形成部を立体形成部領域3aに形成する。
このとき、肩部3Pは、インナーロール11の受け部11aによって内側から確実に支えられながら、インナーロール11及びアウターロール12に挟み込まれた状態で回転加工される。このため、缶1Pの肩部3Pは、薄肉であっても、異常変形、損傷等がしにくい。
その後、インナーロール11、アウターロール12、載置台13は、回転を停止する。また、インナーロール11、アウターロール12は、径方向において肩部3から離れる。これにより、缶1の高さ方向において、インナーロール11、アウターロール12は、缶1に対して干渉しない位置まで退避する。
そして、載置台13を移動させることにより、缶1を加工位置から相対的に離間させる。これにより、缶1を加工位置から退避させる。
また、インナーロール11、アウターロール12は、高さ方向において口部4側に向けて移動することにより、缶1に対して相対的に移動する。これにより、インナーロール11は、口部4から缶1Pの外側に移動する。
次に、本発明の第二実施形態について説明する。
なお、以下の説明及び図面において、前述した第一実施形態と同様の機能を果たす部分には、同一の符号を適宜付して、重複する説明を適宜省略する。
図6(a),(b)に示すように、アウターロール12の回転軸12cは、インナーロール11や載置台13の回転軸に平行ではなく、交差、又はねじれの位置となるように配置している。つまり、アウターロール12の回転軸12cと、インナーロール11の回転軸11cとは、平行ではなく、異なる方向である。
また、このように、フランジ5を形成前の缶1Pの肩部3Pに立体形成部を形成した場合には、その後、さらに口部4を縮径することにより肩部Pを内側に広げ、又は増設することにより、口径を小さくした缶としてもよい。
インナーロール11は、受け部11aから下側に向けて、胴部インナー押圧部11dが設けられている。
胴部インナー押圧部11dは、円筒状の部材である。胴部インナー押圧部11dの周面のハッチングで図示する範囲には、受け部11aと同様に、立体形成部領域2aの立体形成部に対応した形状の凹部及び凸部の少なくとも1つを有する。
胴部アウター押圧部12dは、円筒状の部材である。胴部アウター押圧部12dの周面のハッチングで図示する範囲には、胴部インナー押圧部11dに対応した形状の凹部及び凸部の少なくとも1つを有する。
このように、図7に示すインナーロール11、アウターロール12は、缶1Pの胴部2及び肩部3Pに対して、同じ工程内で加飾することができる。
上記実施形態における缶1及びインナーロール11の寸法設定の一例について説明する。
図8(a)は、缶1の上部分の断面図、インナーロール11を模式的に示す図である。
図8(b)は、図8のB部拡大図である。
図8に示す各符号は、以下を示す。
A(mm):缶1の口部4の口径
B(mm):肩部3の最大外径(つまり、缶1の胴部2の直径)
C(mm):缶1の口部4及び受け部11a間のクリアランス
D(mm):インナーロール11のシャフト11bの軸径
E(mm):受け部外径(受け部11aの最大外径)
W1:缶1の肩部3の傾斜方向に沿った方向の全長
W2:立体形成部設置可能長さ、つまり、缶1の肩部3の傾斜方向に沿った方向において、肩部3のうち口部4側の根元から胴部2側に向かう範囲において、立体形成部領域3aを配置可能な長さ
L1=(B-A)/2
このため、長さL2は、以下の式で表すことができる。
L2=L3
L2=(A-2×C-D)/2
W2/W1=L2/L1=[(A-2×C-D)/2]/[(B-A)/2]
W2/W1=(A-(2×C+D))/(B-A)
上記式は、以下の式に整理できる。
2×C+D=A-(B-A)×W2/W1・・・式1
12≦A-(B-A)×W2/W1・・・式2
さらに、例えば、式2及び「W2/W1≦0.5」が成立する缶1は、上記効果に加えて、肩部3のうち口部4側の根元から胴部2側に向かう範囲において肩部3の半分までの部分に立体形成部領域3aを配置できるという効果を奏する。
また、式2及び「W2/W1≦1」が成立する缶1は、上記効果に加えて、肩部3の全範囲に立体形成部領域3aを配置できるという効果を奏する。
受け部11aの円錐台状側面の斜面の長さW3と、立体形成部設置可能長さW2とは、等しい。
このため、径方向において、受け部11aの突出長さL3は、以下の式で表すことができる。
L3=W3×sinθ=W2×sinθ
このため、受け部外径Eは、
E=D+2×L3
E=D+2×W2×sinθ
E+2×C≦A
D+2×W2×sinθ+2×C≦A
上記式は、以下の式に整理できる。
D≦A-2×(C+W2×sinθ)・・・式3
さらに、クリアランスC(mm)は、前述したように「1≦C」であることが好ましい。このため、インナーロール11は、式3に加えて、「1≦C」を満たすことにより、加工性を向上できる。
(1)アウターロールは、特許文献1の図4のアウターローラ102や、特開2011-005512号公報の図2,3等に記載のアウターロール4のように、回転加工を行う箇所を大径部とし、缶の挿入排出を行う箇所を小径部としてよい。そして、缶の保持手段(載置台)をインナーロールに対し進退移動可能な構造にすることにより、缶の挿入、肩部回転加工、缶排出を行う装置構成としてもよい。
(4)缶は、底部、胴部、蓋部がそれぞれ異なる部材である3ピース缶でもよい。この場合には、底部及び蓋部を設ける前の胴部に対して、立体形成部を形成してもよい。また、この場合には、インナーロールは、口部側ではなく、底部側から缶内部に挿入してもよい。
(6)実施形態において、缶の肩部は、直線状に傾斜した傾斜部分である例を示したが、これに限定されない。缶の肩部は、例えば、湾曲した湾曲部分等でもよい。この場合には、インナーロール、アウターロールの加工面は、この湾曲部分等に対応した湾曲面等を備えていればよい。また、この場合には、実施形態の各構成を、湾曲部分等に対応するように適宜変形することにより、湾曲部分等を有する肩部を、実施形態の概念を適用して加工することができる。
