【発明の属する技術分野】
本発明は、液体包装用の紙パックなど角筒状又は円筒状の紙容器製函用シートの筒状シート貼着個所におけるシート端部のエッジ部分を切削して面取りするための紙容器製函用シート端部切削処理装置に関する。
【0002】
【従来の技術】
一般に角筒状の紙容器は、容器製函用の平板状のブランクシートを平行な所定の折目を介して四角形筒状に折り曲げ、そのシート両端部をヒートシールにて貼着して四角筒体を形成した後、該四角筒体内にボトム成形保持用のマンドレルを装填し、その角筒体の四つの側面板からなる胴部の下端部に連設されたボトム成形用のボトム板をマンドレルにて内面を保持しながら、所定の折目を介して折り曲げてヒートシールにて貼着することによりボトム部を形成した後、角筒体内からマンドレルを抜き取り外す。
【0003】
次に、角筒体の四つの側面板からなる胴部の上端部に連設されたトップ成形用のトップ板側から液状の内容物を充填した後、トップ板を所定の折目を介して折り曲げてヒートシールにて貼着することによりトップ部を形成して、図4(a)に示すような角筒状の紙容器Aが製函される。
【0004】
製函された角筒状の紙容器Aには、図4(a)に示すM部分拡大図である図4(b)に示すように、平板状のブランクシートSを平行な所定の折目を介して四角形筒状に折り曲げ、そのシートSの両端部を貼着した貼着シール部4のある角部2の外側に貼着されたシートSの一端部の外面側縁部に、略直角なエッジ部3が露呈する。
【0005】
そこで、紙容器Aを手で持つ際にエッジ部3によって手指を怪我したり危険が生じないように、従来は、道具を用いて手作業により、露呈したエッジ部3を叩いて平坦に面取りしたり、角丸形状にして、危険を回避するための加工が実施されており、そのために、手加工による労力と時間を費やし、また、手加工によるために加工形状が一定せず、形状ムラが発生し易かった。
【0006】
【発明が解決しようとする課題】
本発明は、容器製函用ブランクシートの両端部を貼着シール部にて貼着して上記のような角筒体とする際に、貼着シール部のある角部発生する略直角なエッジ部の面取り加工を、手作業に依らずに能率的に実施でき、正確で安定した加工形状を得ることができるようにすることにある。
【0007】
【課題を解決するための手段】
本発明の請求項1に係る発明は、紙容器製函用シートSを水平に搬送する搬送手段10と、搬送されるシートSの搬送幅方向の一側端部S1 を切削する円錐形状の切削用回転体27と該回転体27の円周面に対向するシート端部押さえロール28を備えた切削手段20とを備え、前記シートSの一側端部S1 を切削用回転体27とシート端部押さえロール28との対向間に挿入しながら、前記シートSの一端部S1 の片面側のエッジ部3を前記切削用回転体27の円錐形状の傾斜円周面27aに前記押さえロール28にて押し付けながら切削し面取りして面取り部4を形成することを特徴とする紙容器製函用シート端部切削処理装置である。
【0008】
本発明の請求項2に係る発明は、上記請求項1に係る装置において、前記切削用回転体27とシート端部押さえロール28とは一体的に水平移動可能でり、前記シートSの一側端部S1 に対して離接調整可能であることを特徴とする紙容器製函用シート端部切削処理装置である。
【0009】
【発明の実施の形態】
本発明の紙容器製函用シート端部切削処理装置の実施の形態を、図1(a)に示す本発明装置の正面図、(b)に示す部分側面図図面に基づいて、以下に詳細に説明する。
【0010】
本発明装置は、図1(a)に示すように、平坦な紙容器製函用シートS(製函用ブランクシート)を水平に搬送する搬送手段10を備える。
【0011】
搬送手段10は、例えば図1(a)及び(b)に示すように、装置本体フレームFに軸支されモーターにて駆動回転するプーリー12と、自由回転するプーリー13とに巻回した無端状の下部ベルト11と、装置本体フレームFに軸支され前記プーリー12と伝動ギア等を介して連動回転するプーリー16と、自由回転するプーリー17とに巻回した無端状の上部ベルト15とにより構成され、平坦な紙容器製函用シートSは、矢印方向に回転送行する上下部ベルト11、12によって挟み込まれて搬送される。
【0012】
また、該上下部ベルト11、12の中間部位には、必要に応じて適宜数対の対向押圧ロール14、18が装置本体フレームFに軸支されて配置され、前記シートSはベルト11、12を介して挟み込まれて、矢印方向に搬送される。
【0013】
また、上記搬送手段10は、ベルト11、15を省略した駆動回転する複数対の対向押圧ロール14、18によって、前記シートSを挟み込んで矢印方向に搬送するようにしてもよい。
【0014】
搬送手段10の搬送方向の下流側には、搬送される前記シートSの搬送幅方向の一側端部S1 を切削する円錐形状の切削用回転体27と、該回転体27の円周面27aに対向するシート端部押さえロール28とを備えた切削手段20を備える。
【0015】
切削手段20は、装置本体フレームFに水平に取付け配置した水平テーブル21の上面に設けた水平リニアガイド(図示せず)に沿って水平直線状に摺動移動可能な可動テーブル22と、該可動テーブル22を固定するストッパー部22aを備え、該可動テーブル22上には、電動モーター24と、軸受フレーム23が取付けられ、該軸受フレーム23には、支軸27bにて切削用回転体27と支軸28aにてシート端部押さえロール28とが軸支されている。
【0016】
電動モーター24は、その駆動回転主軸24aに取付けた駆動ギア25と、伝動チェーン25a(又はギア)と、支軸27bに取付けた伝動ギア26と、支軸27bとを連動させて切削用回転体27を正転方向(シートSの搬送方向と同じ方向)又は逆転方向(シートSの搬送方向に対して反対方向)に回転させることができる。なお、シート端部押さえロール28は自由回転でもよいし、その支軸28aを支軸27bに取付けた伝動ギア26に伝動チェーン(又はギア)を介して連動させて正転方向(シートSの搬送方向と同じ方向)に駆動回転させる構造でもよい。
【0017】
製函用シートSの搬送幅方向の一側端部S1 に対する切削用回転体27の位置決めは、予め可動テーブル22と共に切削用回転体27を適宜に水平移動させることにより調整して位置決めし、位置決め後は、ストッパー部22aのハンドル22bを締圧方向に回転させて水平テーブル21に対して可動テーブル22を固定する。
【0018】
図1(b)に示すように、搬送手段10により平坦な紙容器製函用シートSを切削手段20方向に搬送速度V1 にて搬送しながら、図2の部分拡大正面図に示すように、そのシートSの搬送幅方向の一側端部S1 を切削用回転体27とシート端部押さえロール28との対向間に挿入する。
【0019】
続いて、前記シートSを搬送速度V1 にて搬送を継続しながら、そのシートSの一側端部S1 を、回転速度V2 にて回転する切削用回転体27の円錐形状の傾斜円周面27a側に押さえロール28にて押し付けながら(この際に押さえロール28はシートSの一側端部S1 面に押圧接触しており、シートSの一側端部S1 面を押圧しながら、シートSの搬送移動に追従して回転する)、その一側端部S1 の片面側(図面ではシートS下面側)の直角なエッジ部3を回転する切削用回転体27の円錐形状の傾斜円周面27aに押し付けるようにして、傾斜円周面27aの表面に設けられた微細な尖鋭凸状(又は尖鋭砂目状)の切削面(又はヤスリ面)によって切削することにより面取する。
【0020】
これによって一側端部S1 にあった直角なエッジ部3部分に平坦面による面取り部4が、そのシートSの搬送幅方向の一側端部S1 に沿って形成される。なお本発明においては、面取り部4は、シートSの搬送幅方向の一側端部S1 の片面側の直角なエッジ部3部分だけでなく、一側端部S1 の両面側の直角なエッジ部3部分、あるいは、シートSの搬送幅方向の他の側端部の片面若しくは両面側の直角なエッジ部3部分に対して施してもよい。
【0021】
図3(a)は、平板状のブランクシートSの搬送幅方向の一側端部S1 の下面側の角部3を、上記装置により切削し面取りして、面取り部4を加工形成した状態を示す側断面図である。
【0022】

【0023】
前記切削手段20の切削用回転体27の回転方向と搬送手段10によるシートSの搬送方向とは、互いに同一方向であってもよいし、互いに反対方向であってもよい。
【0024】
切削用回転体27の回転方向と、シートSの搬送方向が同一方向である場合には、前記切削用回転体27の回転速度V2 と、シートSの搬送速度V1 との関係は、
V1 <V2

Then, the flat paper container box-forming sheet S is conveyed while being sandwiched between the upper and lower belts 11 and 12 which are transferred in the direction of the arrow.
[0012]
In the intermediate portion between the upper and lower belts 11, 12, an appropriate number of pairs of opposing pressing rolls 14, 18 are disposed so as to be pivotally supported by the apparatus main body frame F as necessary. And is conveyed in the direction of the arrow.
[0013]
Further, the conveying means 10 may sandwich the sheet S and convey the sheet S in the direction of the arrow by a plurality of pairs of opposing pressing rolls 14 and 18 which are driven and rotated without the belts 11 and 15.
[0014]
On the downstream side in the conveying direction of the conveying means 10, a conical cutting rotary body 27 for cutting one side end S1 of the sheet S to be conveyed in the conveying width direction, and a circumferential surface 27a of the rotary body 27 And a cutting means 20 provided with a sheet end pressing roll 28 facing the sheet.
[0015]
The cutting means 20 includes a movable table 22 that can slide and move in a horizontal straight line along a horizontal linear guide (not shown) provided on an upper surface of a horizontal table 21 that is mounted and arranged horizontally on the apparatus main body frame F; An electric motor 24 and a bearing frame 23 are mounted on the movable table 22. The bearing frame 23 supports the cutting rotary body 27 with a support shaft 27b. A sheet end pressing roll 28 is supported by a shaft 28a.
[0016]
The electric motor 24 includes a driving gear 25 mounted on the driving rotary main shaft 24a, a transmission chain 25a (or gear), a transmission gear 26 mounted on a support shaft 27b, and a rotary shaft 27 can be rotated in the normal rotation direction (the same direction as the sheet S transport direction) or the reverse rotation direction (the opposite direction to the sheet S transport direction). The sheet end pressing roll 28 may rotate freely, or its support shaft 28a may be interlocked with a transmission gear 26 attached to a support shaft 27b via a transmission chain (or gear) in a forward rotation direction (conveyance of the sheet S). (The same direction as the direction).
[0017]
The positioning of the cutting rotary body 27 with respect to the one side end S1 of the box-making sheet S in the transport width direction is adjusted and positioned by moving the cutting rotary body 27 together with the movable table 22 in advance as appropriate. Thereafter, the movable table 22 is fixed to the horizontal table 21 by rotating the handle 22b of the stopper portion 22a in the tightening direction.
[0018]

Subsequently, while continuing to convey the sheet S at the conveying speed V1, one side end S1 of the sheet S is conical-shaped inclined circumferential surface 27a of the cutting rotary body 27 rotating at the rotating speed V2. (In this case, the pressing roll 28 is in pressure contact with one side end S1 surface of the sheet S, and presses the one side end S1 surface of the sheet S while pressing the sheet S). The conical inclined circumferential surface 27a of the rotary body 27 for cutting which rotates the right-angled edge portion 3 on one side (the lower surface side of the sheet S in the drawing) of one end S1 of the one side end S1. To be chamfered by cutting with a fine sharp convex (or sharp grain) cutting surface (or file surface) provided on the surface of the inclined circumferential surface 27a.
[0020]
As a result, a chamfered portion 4 with a flat surface is formed along the one edge S1 of the sheet S in the conveying width direction at the right edge 3 at the one edge S1. In the present invention, the chamfered portion 4 includes not only the right-side edge 3 on one side of the one-side end S1 of the sheet S in the conveying width direction but also the right-angled edge on both sides of the one-side end S1. It may be applied to three portions, or three right-angled edge portions on one side or both sides of the other side end in the conveying width direction of the sheet S.
[0021]
FIG. 3A shows a state in which the corner 3 on the lower surface side of the one side end S1 of the flat blank sheet S in the conveying width direction is cut and chamfered by the above-described apparatus to form the chamfered portion 4. FIG.
[0022]
