Description

【0001】
【発明の属する技術分野】
本発明はフィルム状の物を巻いたロール状物を搬送或は保管のために使用されるコアホルダー及びこのコアホルダーを用いた梱包方法に係り、特に耐衝撃性構造を有するコアホルダーとそのコアホルダーを用いた梱包方法に関するものである。
【0002】
【従来の技術】
従来は一般的に、例えば図6に示す如く、フィルム51をコア(心材)52に巻いたロール状物53を搬送或は保管等をする際には、一対のコアホルダー54をロール状物53の両端に配置し、かつ該コアホルダー54の中心部に設けられたコア支持部55をロール状物53のコア52内に挿入し、これによってロール状物53を宙吊り状態にして、フィルム51が自重によるストレスで変形することを防止しながら、ロール状物53を搬送或は保管していた。
【0003】
前記コア52としては、熱可塑性樹脂、例えばABS樹脂等を用いて成形されたプラスチック丸筒が使用されていた。また、このコア52に巻かれるフィルム51としては、例えばドライフィルムレジスト(DFR)等がある。前記コアホルダー54は一般的に熱可塑性樹脂を射出成形することによって枠状に形成されていた。
【0004】
前述のDFRのフィルム51は、電子機器のプリント基板を作るために大量に使用されている。最近、コンピューター、家電、携帯電話などの電子機器は高度に発達し、ミクロン単位の精密な配線がプリント基板技術を用いて、工業的に大量に生産されている。このような精密なプリント基板を作る際に用いられるDFRにはわずかな傷や厚みムラも許されないのが現状である。
【0005】
従って、ロール状物53が搬送或は保管時にこのロール状物53を梱包した容器の一部に接触したり、或はロール状物53の自重により、または外側からの力によってフィルム51が変形、被傷または厚みムラを起こさないようにすることが重要であった。そのためにも、前述の図6に例示する如く、従来もロール状物53をコアホルダー54によって宙吊りするように梱包し、この状態で搬送或は保管していた。
【0006】
前述のロール状物53を保持するコアホルダー54としては、例えば図7に示すような構造のコアホルダー54が使用されていた。該コアホルダー54に示す如く、従来一般的に使用されていたコアホルダーは、前記コア52を支持するコア支持部55の外側に外枠56が設けられ、かつこれ等のコア支持部55と外枠56とは複数のリブ57によって相互に直接連結されて構成されていた。
【0007】
【発明が解決しようとする課題】
然るに、前述のコアホルダー54は、コア支持部55と外枠56とが複数のリブ57で直接連結されている構造であるので、このコアホルダー54を使用してロール状物53を梱包した場合には、輸送中の荷扱いや落下などによって衝撃が発生すると、コアホルダー54自体にその衝撃を充分に吸収する能力がないために、特にコアホルダー54の外枠56に掛かる大きな衝撃等の外力がリブ57を介してコア支持部55に伝達されるので、コア支持部55で支持されているロール状物53のフィルム51やコア52が損傷或は破損したり、或はコアホルダー54自体も破損してロール状物53の保持機能を無くし、結果的にロール状物53を傷つけてしまい、ロール状物53のフィルム51の機能を阻害してしまうトラブルが発生する問題があった。
【0008】
本発明に係るコアホルダー及びそのコアホルダーを用いた梱包方法は、前述の従来の大きな問題点に鑑み開発された全く新しい技術であって、特にコアホルダーを特定の構造にすることによって、ロール状物の輸送中等の荷扱いや落下等による衝撃が発生した場合にも、この衝撃をコアホルダー自体で吸収し、該衝撃がロール状物のコアやフィルムに直接伝達されて、これ等のコアやフィルムが破損或は損傷することを防止するようにした全く新しいコアホルダー及び梱包方法を提供するものである。
【0009】
【課題を解決するための手段】
本発明に係るコアホルダーは、前述の従来の問題点を根本的に改善した発明であって、その発明の要旨は、ドライフィルムレジストのフィルムを巻いたロール状物の搬送、保管等時に用いられるコアホルダーに於いて、該ロール状物のコアを支えるコア支持部と外枠との間に中間枠を介在させ、かつ前記コア支持部と中間枠とを相互に連結する全ての内側リブと、該中間枠と外枠とを相互に連結する全ての外側リブとが互いに同一線上にこないように配列して構成し、該コア支持部と同芯で、該コア支持部の外周面と遊合する内周面を有する凹部を設けないことを特徴としたコアホルダーである。
【0010】
本発明に係るコアホルダーは、前述のようにドライフィルムレジストのフィルムを巻いたロール状物のコアを支えるコア支持部と外枠との間に中間枠を介在させ、かつコア支持部と中間枠とを相互に連結する全ての内側リブと、該中間枠と外枠とを相互に連結する全ての外側リブとが互いに同一線上にこないように配列して構成したので、コアホルダーに加わった落下衝撃等の大きな外力を前記中間枠と、及び同一線上にこないように相互に配列された外側リブと内側リブとの組合わせによる総合作用で効率吸収することが出来る。
【0011】
従って、例えばコアホルダーを用いて梱包されたロール状物が所定の高さから落下した場合にも、コアホルダーの外枠に掛かる大きな衝撃をそのままコア支持部に伝達することがなく、外枠に掛かる大きな衝撃を前述のように中間枠と同一線上にこないように配列された外側リブと内側リブとで吸収することが出来る。
【0012】
そのために、仮にコアホルダーの外枠が前述のような衝撃等の大きな外力によって破損するような場合にも、コア支持部で支えているロール状物に大きな外力がそのまま伝達されることを防止出来、これによってロール状物のコア或はコアに巻き取られたフィルムが破損或は損傷する恐れを極めて少なくすることが出来る。
【0013】
【発明の実施の形態】
図により本発明に係るコアホルダーの一実施例を具体的に説明すると、図1は本発明に係るコアホルダーの正面図及び平面図、図2は図1のコアホルダーの背面図、図3は他例のコアホルダーの正面図及び平面図である。
【0014】
本発明者等は長年に亘って種々の実験と研究を繰返すことによって、前述の従来のコアホルダー54よりも衝撃等の大きな外力を効率良く吸収することが出来るコアホルダーについて鋭意研究した結果、例えば、図1及び図2に示す実施例1のコアホルダー1或は図3に示す実施例2のコアホルダー8を開発するに至った。
【0015】
〔実施例1〕
図1及び図2に於いて、1はコアホルダーであって、外枠2の中心部にはロール状物のコアを支えることが出来るコア支持部3が設けられている。該コア支持部3と外枠2との間にはそのほぼ中間に中間枠4が介在されている。
【0016】
前記コア支持部3と中間枠4とは、コア支持部3より外側に向かって放射状に伸びた複数の内側リブ5を介して相互に連結されている。また、該中間枠4と外枠2とは複数の外側リブ6を介して相互に連結されている。そして中間枠4から内側に伸びる内側リブ5と、中間枠4から外側に伸びる外側リブ6は、夫々が互いにその延長線上にならないように、即ち、両者は夫々同一線上にこないように配置されている。
【0017】
前述の従来のコアホルダー54のように、コア支持部55と外枠56とを複数のリブ57で相互に直接連結した場合には、例えば外枠とコア支持部を連結するリブを太くする等して、ロール状物53のコア52を支える強さを強くすればするほど、落下衝撃などによってロール状物53のフィルム51やコア52の破損或は損傷が起こり易くなるが、本発明のように、外枠2とコア支持部3との間に中間枠4を介在させ、さらにコア支持部3と中間枠4とを相互に連結する複数の内側リブ5と、中間枠4と外枠2とを相互に連結する複数の外側リブ6とを夫々同一線上にこないように配置した構造にした場合には、このような構造を持ったコアホルダー1は衝撃力等の外力を極めて効率よく吸収することが出来ることを見出した。
【0018】
従って、このコアホルダー1を使用して前記ロール状物53を梱包した場合には、仮に輸送時等にロール状物53が落下して大きな衝撃が加わった場合にも、ロール状物53の両側に配置したコアホルダー1が、その衝撃を効果的に吸収するので、ロール状物53のフィルム51やコア52の破損或は損傷を起こす心配がない。
【0019】
前述の図1及び図2に示す如く、内側リブ5或は外側リブ6の裏側(ロール状物53のフィルム51に接する面)には、所定の肉厚を持った面板7を一体的に形成することが出来る。前述の内側リブ5、外側リブ6及び面板7の幅及び厚みは、コアホルダー1で支持するロール状物53の重量等に応じて、予め所定の数値に規定することが出来る。また、前記面板7には、内側リブ5或は外側リブ6の周辺に切り込み開口部を設けることで、コアホルダー1が落下衝撃を受けた際に、これを変形させて衝撃応力を吸収し易くすることが出来る。
【0020】
〔実施例2〕
図3に示す如く、実施例2のコアホルダー8に於いては、コア支持部3と外枠2との中間に円形の中間枠9を介在させ、コア支持部3と中間枠9とを複数の内側リブ5で相互に連結し、中間枠9と外枠2とを複数の外側リブ6で相互に連結することによって構成した。この実施例2のコアホルダー8の場合にも、前記実施例1のコアホルダー1と同様に、複数の内側リブ5と外側リブ6とが同一線上にこないように配列して構成した。
【0021】
本発明に係るロール状物の梱包方法を実施するに当っては、前述の図6に示すようなロール状物の両側に本発明に係るコアホルダー1或はコアホルダー8を配置し、これ等のコアホルダー1、8のコア支持部3をロール状物のコアの側端開口部に挿入して取付け、所定寸法の段ボール箱の中に2本のロール状物を並列して収納し、これ等のロール状物を夫々コアホルダー1、8によって宙吊りにするように構成して、その後で15℃の部屋に一昼夜放置した後、市販の荷造り用ポリプロピレンバンドで段ボール箱をしばり梱包した。
【0022】
前述の本発明に係るコアホルダー1、8の性能を試験して比較検討するために、本発明者等は2つの比較例1、2のコアホルダー10、11を作成し、これらのコアホルダー10、11と、本発明に係る前記コアホルダー1、8とを後述のように試験によって比較した。従って、先ず比較例1、2のコアホルダー10、11の構成について説明する。また、前記本発明のコアホルダー1、8と比較例1、2のコアホルダー10、11は、いずれも同一グレードのポリプロピレン樹脂を使用し、射出成形用の成形金型を使用して一体成形した。
【0023】
〔比較例1〕
比較例1のコアホルダー10は、図4に示す如く、外枠1、2の中心部にコア支持部13を配置し、外枠12とコア支持部13とを、ほぼ同一の太さを持った複数のリブ14で相互に直接連結して構成したものである。
【0024】
〔比較例2〕
比較例2のコアホルダー11は、図5に示す如く、基本的構成は前記比較例1のコアホルダー10と全く同じである。両者の原理的大きな差異は、コアホルダー10の場合は、複数のリブ14の太さをほぼ同一にしたのに対し、コアホルダー11の場合には、複数のリブ14の内の所定場所のリブを太径にして補強リブ14a形成した点で異なっている。
【0025】
〔試験例〕
前述の本発明に係るコアホルダー1、8の効果を試験するために、前記比較例で製作したコアホルダー10、11を用いて夫々の落下試験を実施した。
【0026】
旭化成株式会社製のサンフォートAQ−4038 幅513mm×180m(重量8.8kg)、ABSコア550mm(厚さ3.5mm、外径83mm使用)に巻いたロール状物をダンボール箱に、実施例1、2のコアホルダー1、8と及び比較例1、2のコアホルダー10、11を用いて、1箱にロール状物をそれぞれ2本づつ梱包した。そして、15℃の部屋に一昼夜放置した後、市販の荷造り用ポリプロピレンバンド(通称PPバンド)でしばり、フォークリフトで箱が底面と平行になるように、所定の高さまで吊り上げ、PPバンドを鋏で切断して、平滑なコンクリート床面に落下させコア及びコアホルダーの破損状況を調べた。
【0027】
この試験方法は一度に4個のコアホルダーを使用し、2本のコアの両側の4箇所が披検査対象となる。1本目のロールをAとB、2本面のロールをCとDとしてテスト結果を表示した。本発明の実施例1、2のコアホルダー1、8の場合の結果を表1に示す。コアホルダーの外枠まで破損すると保持機能が少し低下するが、リブの一部が破損した程度では保持機能は十分に残っておりロールに損傷を与えていない。従って、落下高さ140cmまでは製品のロール状物に実害は及んでいないことが確認された。
【0028】

【0029】
これに対して、比較例1、2のコアホルダー10、11の場合には、次の表2に示す如く、落下高さが40cm或は50cmの場合でも、コアにひび割れや破損欠落が始まっており、製品のロール状物に実害が及んでいることが確認された。
【0030】

【0031】
前述の表1及び表2によって明らかな如く、本発明に係るコアホルダー1、8は、比較例1、2、(或は従来の)コアホルダー10、11に比較して、高い処から落下した場合の大きな衝撃力を効率良く吸収することが出来、本発明に係るコアホルダー1、8を使用した場合には、フィルム等のロール状に巻かれたロール状物を極めて有効に保護することが出来ることが明らかとなった。本発明に係るコアホルダー1、8は、特にDFR用に用いると好ましい効果を得ることが出来る。
【0032】
本発明の梱包方法を実施した場合には、DFR等のフィルムメーカーからDFR等のフィルムユーザーまでの搬送手段が宅配便等の一般の輸送ネットワークを利用することが出来るようになった。特に小口輸送の場合、コストの高い特別仕立ての専用便を敢えて使用する必要がなくなった。そのことにより、DFR等のフィルムの流通コストの削減に著しく貢献することが可能となり、工業的にも極めて価値のある発明である。なお、本発明はフィルムの巻物であれば全てに応用することが可能で、DFRのみに限定されるものではない。
【0033】
【発明の効果】
本発明に係るコアホルダーは、前述のようにロール状物のコアを支えるコア支持部と外枠との間に中間枠を介在させ、かつコア支持部と中間枠とを相互に連結する内側リブと、該中間枠と外枠とを相互に連結する外側リブとが互いに同一線上にこないように配列して構成したので、コアホルダーに加わった落下衝撃等の大きな外力を前記中間枠と、及び同一線上にこないように相互に配列された外側リブと内側リブとの組合わせによる総合作用で効率吸収することが出来る等の大きな効果を有している。
【0034】
従って、例えばコアホルダーを用いて梱包されたロール状物が所定の高さから落下した場合にも、コアホルダーの外枠に掛かる大きな衝撃をそのままコア支持部に伝達することがなく、外枠に掛かる大きな衝撃を前述のように中間枠と同一線上にこないように配列された外側リブと内側リブとで総合的に吸収することが出来る効果を有している。
【0035】
そのために、仮にコアホルダーの外枠が前述のような衝撃等の大きな外力によって破損するような場合にも、コア支持部で支えているロール状物に大きな外力がそのまま伝達されることを防止出来、これによってロール状物のコア或はコアに巻き取られたフィルムが破損或は損傷する恐れを極めて少なくすることが出来る等の効果を有している。
【0036】
本発明に係る梱包方法は、前述のように、コア支持部と外枠との間に中間枠を設けると共に前記コア支持部と中間枠との間に設けた内側リブと該中間枠と外枠との間に設けた外側リブとが相互に同一線上にこないように配列して構成した一対のコアホルダーをロール状物の両端部に配置し、かつこれ等のコアホルダーのコア支持部でロール状物のコアを支持することによって梱包したので、輸送中等に梱包されたロール状物が落下して大きな衝撃が発生した場合にも、この衝撃をコアホルダーで吸収することが出来るので、梱包されたロール状物のコア或はフィルムが破損したり或は損傷することを防止出来る等の多大な効果を有している。

BACKGROUND OF THE INVENTION
The present invention relates to a core holder used for transporting or storing a roll-shaped article wound with a film-like article, and a packing method using the core holder, and more particularly, a core holder having an impact-resistant structure and its core The present invention relates to a packing method using a holder.
[0002]
[Prior art]
Conventionally, generally, for example, as shown in FIG. 6, when transporting or storing a roll 53 in which a film 51 is wound around a core (core material) 52, a pair of core holders 54 are rolled 53 The core support portion 55 disposed at both ends of the core holder 54 and inserted in the center portion of the core holder 54 is inserted into the core 52 of the roll-like object 53, whereby the roll-like object 53 is suspended and the film 51 is The roll 53 was transported or stored while preventing deformation due to stress due to its own weight.
[0003]
As the core 52, a plastic round cylinder formed using a thermoplastic resin, for example, an ABS resin or the like has been used. The film 51 wound around the core 52 includes, for example, a dry film resist (DFR). The core holder 54 is generally formed in a frame shape by injection molding of a thermoplastic resin.
[0004]
The DFR film 51 described above is used in large quantities to produce printed circuit boards for electronic devices. Recently, electronic devices such as computers, home appliances, and mobile phones have been highly developed, and fine wirings in micron units have been industrially produced in large quantities using printed circuit board technology. At present, slight scratches and uneven thickness are not allowed in the DFR used when producing such a precision printed circuit board.
[0005]
Accordingly, the film 51 is deformed by contact with a part of the container in which the roll 53 is packed during transportation or storage, or by the weight of the roll 53 or by a force from the outside. It was important to avoid scratches or uneven thickness. For this purpose, as illustrated in FIG. 6 described above, the roll-like object 53 is conventionally packaged so as to be suspended by the core holder 54, and transported or stored in this state.
[0006]
For example, a core holder 54 having a structure as shown in FIG. 7 is used as the core holder 54 for holding the roll-shaped object 53 described above. As shown in the core holder 54, the core holder generally used conventionally has an outer frame 56 provided outside the core support portion 55 that supports the core 52, and the core support portion 55 and the outside of the core support portion 55. The frame 56 is configured to be directly connected to each other by a plurality of ribs 57.
[0007]
[Problems to be solved by the invention]
However, since the core holder 54 has a structure in which the core support portion 55 and the outer frame 56 are directly connected by the plurality of ribs 57, when the roll-shaped object 53 is packed using the core holder 54, If an impact occurs due to handling or dropping during transportation, the core holder 54 itself does not have the ability to absorb the impact sufficiently, so that an external force such as a large impact applied to the outer frame 56 of the core holder 54 is particularly large. Since it is transmitted to the core support portion 55 via the rib 57, the film 51 and the core 52 of the roll 53 supported by the core support portion 55 are damaged or broken, or the core holder 54 itself is also broken. Thus, there is a problem in that the function of holding the roll-like object 53 is lost, and as a result, the roll-like object 53 is damaged, and the function of the film 51 of the roll-like object 53 is hindered. There was.
[0008]
The core holder and the packing method using the core holder according to the present invention are a completely new technology developed in view of the above-mentioned large problems of the prior art, and in particular, by making the core holder a specific structure, Even when an impact due to handling or dropping occurs during transportation of an object, the impact is absorbed by the core holder itself, and the impact is directly transmitted to the core or film of the roll-shaped object. It is intended to provide a completely new core holder and packing method which prevent the breakage or damage of the core.
[0009]
[Means for Solving the Problems]
The core holder according to the present invention is an invention in which the above-mentioned conventional problems are fundamentally improved, and the gist of the invention is used for transporting, storing, and the like of a roll-like material wound with a dry film resist film. In the core holder, all inner ribs that interpose the intermediate frame between the core support part and the outer frame that support the core of the roll-shaped article, and interconnect the core support part and the intermediate frame; All the outer ribs that interconnect the intermediate frame and the outer frame are arranged so as not to be collinear with each other, and are concentric with the core support portion and loosely coupled with the outer peripheral surface of the core support portion It is a core holder characterized by not providing a recess having an inner peripheral surface .
[0010]
The core holder according to the present invention includes an intermediate frame interposed between the core support portion and the outer frame that support the core of the roll-shaped product wound with the dry film resist film as described above, and the core support portion and the intermediate frame. Since all the inner ribs that mutually connect the outer frame and all the outer ribs that mutually connect the intermediate frame and the outer frame are arranged so as not to be collinear with each other, the fall applied to the core holder A large external force such as an impact can be efficiently absorbed by the combined action of the intermediate frame and the combination of the outer rib and the inner rib that are arranged so as not to be on the same line.
[0011]
Therefore, for example, even when a roll-shaped product packed using a core holder falls from a predetermined height, a large impact applied to the outer frame of the core holder is not transmitted to the core support as it is, A large impact can be absorbed by the outer rib and the inner rib arranged so as not to be collinear with the intermediate frame as described above.
[0012]
For this reason, even if the outer frame of the core holder is damaged by a large external force such as an impact as described above, a large external force can be prevented from being transmitted as it is to the roll-like object supported by the core support portion. As a result, the risk of breakage or damage to the roll core or the film wound around the core can be greatly reduced.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a front view and a plan view of a core holder according to the present invention, FIG. 2 is a rear view of the core holder of FIG. 1, and FIG. It is the front view and top view of a core holder of other examples.
[0014]
As a result of earnestly researching the core holder that can absorb a large external force such as impact more efficiently than the conventional core holder 54 described above by repeating various experiments and researches over many years, for example, The core holder 1 of the first embodiment shown in FIGS. 1 and 2 or the core holder 8 of the second embodiment shown in FIG. 3 has been developed.
[0015]
[Example 1]
1 and 2, reference numeral 1 denotes a core holder, and a core support portion 3 capable of supporting a roll-shaped core is provided at the center of the outer frame 2. An intermediate frame 4 is interposed approximately between the core support portion 3 and the outer frame 2.
[0016]
The core support 3 and the intermediate frame 4 are connected to each other via a plurality of inner ribs 5 that extend radially outward from the core support 3. The intermediate frame 4 and the outer frame 2 are connected to each other via a plurality of outer ribs 6. The inner rib 5 extending inward from the intermediate frame 4 and the outer rib 6 extending outward from the intermediate frame 4 are arranged so that they are not on the extension line of each other, that is, they are not on the same line. Yes.
[0017]
When the core support portion 55 and the outer frame 56 are directly connected to each other by the plurality of ribs 57 as in the conventional core holder 54 described above, for example, the rib that connects the outer frame and the core support portion is thickened. As the strength of supporting the core 52 of the roll-shaped object 53 is increased, the film 51 and the core 52 of the roll-shaped object 53 are more likely to be damaged or damaged by a drop impact or the like. In addition, an intermediate frame 4 is interposed between the outer frame 2 and the core support portion 3, and a plurality of inner ribs 5 that interconnect the core support portion 3 and the intermediate frame 4, and the intermediate frame 4 and the outer frame 2. When the plurality of outer ribs 6 that are connected to each other are arranged so as not to be on the same line, the core holder 1 having such a structure absorbs external forces such as impact force very efficiently. I found out that I can do it.
[0018]
Therefore, when the roll-like object 53 is packed by using the core holder 1, both sides of the roll-like object 53 are provided even when the roll-like object 53 falls and a large impact is applied during transportation. Since the core holder 1 disposed in the position effectively absorbs the impact, there is no fear that the film 51 or the core 52 of the roll-like object 53 is broken or damaged.
[0019]
As shown in FIGS. 1 and 2 described above, a face plate 7 having a predetermined thickness is integrally formed on the back side of the inner rib 5 or the outer rib 6 (the surface of the roll-shaped object 53 that contacts the film 51). I can do it. The widths and thicknesses of the inner rib 5, the outer rib 6 and the face plate 7 can be specified in advance in accordance with the weight of the roll-like object 53 supported by the core holder 1. Further, the face plate 7 is provided with a cut opening around the inner rib 5 or the outer rib 6 so that when the core holder 1 receives a drop impact, it is deformed to easily absorb the impact stress. I can do it.
[0020]
[Example 2]
As shown in FIG. 3, in the core holder 8 of the second embodiment, a circular intermediate frame 9 is interposed between the core support portion 3 and the outer frame 2, and a plurality of core support portions 3 and intermediate frames 9 are provided. The inner frame 5 is connected to each other, and the intermediate frame 9 and the outer frame 2 are connected to each other by a plurality of outer ribs 6. Also in the case of the core holder 8 of the second embodiment, like the core holder 1 of the first embodiment, the plurality of inner ribs 5 and outer ribs 6 are arranged so as not to be on the same line.
[0021]
In carrying out the method for packing a roll-shaped object according to the present invention, the core holder 1 or the core holder 8 according to the present invention is arranged on both sides of the roll-shaped object as shown in FIG. The core support portions 3 of the core holders 1 and 8 are inserted and attached to the side end openings of the roll-shaped core, and the two roll-shaped items are stored in parallel in a corrugated cardboard box of a predetermined size. Each of the rolls was suspended in the air by the core holders 1 and 8, respectively, and then left in a room at 15 ° C. for a whole day and night, and then the cardboard box was packed with a commercially available polypropylene band for packing.
[0022]
In order to test and compare the performance of the above-described core holders 1 and 8 according to the present invention, the present inventors created two core holders 10 and 11 of Comparative Examples 1 and 2, and these core holders 10 and 10. 11 and the core holders 1 and 8 according to the present invention were compared by a test as described later. Therefore, first, the configuration of the core holders 10 and 11 of Comparative Examples 1 and 2 will be described. Further, the core holders 1 and 8 of the present invention and the core holders 10 and 11 of Comparative Examples 1 and 2 are all integrally molded using the same grade of polypropylene resin and using a molding die for injection molding. .
[0023]
[Comparative Example 1]
As shown in FIG. 4, the core holder 10 of Comparative Example 1 has a core support portion 13 disposed at the center of the outer frames 1 and 2, and the outer frame 12 and the core support portion 13 have substantially the same thickness. A plurality of ribs 14 are directly connected to each other.
[0024]
[Comparative Example 2]
As shown in FIG. 5, the core holder 11 of Comparative Example 2 has the same basic configuration as the core holder 10 of Comparative Example 1. The major difference between the two is that, in the case of the core holder 10, the thickness of the plurality of ribs 14 is substantially the same, whereas in the case of the core holder 11, the ribs at predetermined positions among the plurality of ribs 14. Is different in that the reinforcing ribs 14a are formed.
[0025]
[Test example]
In order to test the effects of the core holders 1 and 8 according to the present invention described above, drop tests were performed using the core holders 10 and 11 manufactured in the comparative example.
[0026]
Asahi Kasei Co., Ltd. Sunfort AQ-4038 width 513 mm x 180 m (weight 8.8 kg), ABS core 550 mm (thickness 3.5 mm, outer diameter 83 mm used) rolled material in a cardboard box, Example 1 Two core holders 1 and 8 and the core holders 10 and 11 of Comparative Examples 1 and 2 were used to pack two rolls in one box. After leaving it in the room at 15 ℃ for a whole day and night, it is fastened with a commercially available polypropylene band for packing (commonly called PP band). Then, it was dropped on a smooth concrete floor and the damage state of the core and the core holder was examined.
[0027]
In this test method, four core holders are used at a time, and four places on both sides of the two cores are to be inspected. The test results are displayed with A and B as the first roll and C and D as the two rolls. Table 1 shows the results for the core holders 1 and 8 of Examples 1 and 2 of the present invention. If the outer frame of the core holder is broken, the holding function is slightly lowered. However, the holding function remains sufficiently as long as a part of the rib is broken, and the roll is not damaged. Therefore, it was confirmed that no actual damage was exerted on the roll of the product up to a drop height of 140 cm.
[0028]
[Table 1]
Figure 0004707285
[0029]
On the other hand, in the case of the core holders 10 and 11 of the comparative examples 1 and 2, as shown in the following Table 2, even when the drop height is 40 cm or 50 cm, the core starts to crack or break. As a result, it was confirmed that the product rolls were actually damaged.
[0030]
[Table 2]
Figure 0004707285
[0031]
As is apparent from Table 1 and Table 2 described above, the core holders 1 and 8 according to the present invention dropped from a higher position as compared with Comparative Examples 1 and 2 (or conventional) core holders 10 and 11. The large impact force can be efficiently absorbed, and when the core holders 1 and 8 according to the present invention are used, a roll-like material wound in a roll shape such as a film can be protected extremely effectively. It became clear that it could be done. The core holders 1 and 8 according to the present invention can obtain a preferable effect particularly when used for DFR.
[0032]
When carrying out the packing method of the present invention, a transportation means from a film manufacturer such as DFR to a film user such as DFR can use a general transportation network such as a home delivery service. In particular, in the case of small-lot transportation, it is no longer necessary to dare to use specially tailored flights with high costs. This makes it possible to make a significant contribution to the reduction of the distribution cost of films such as DFR, and is an industrially extremely valuable invention. Note that the present invention can be applied to all film rolls and is not limited to DFR.
[0033]
【The invention's effect】
The core holder according to the present invention includes an inner rib that interposes an intermediate frame between the core support portion and the outer frame that support the core of the roll-shaped article as described above, and connects the core support portion and the intermediate frame to each other. And the outer ribs that interconnect the intermediate frame and the outer frame are arranged so as not to be on the same line as each other, so that a large external force such as a drop impact applied to the core holder is applied to the intermediate frame, and It has such a great effect that it can absorb the efficiency by the combined action of the combination of the outer rib and the inner rib that are arranged so as not to be on the same line.
[0034]
Therefore, for example, even when a roll-shaped product packed using a core holder falls from a predetermined height, a large impact applied to the outer frame of the core holder is not transmitted to the core support as it is, As described above, a large impact can be absorbed by the outer rib and the inner rib arranged so as not to be collinear with the intermediate frame as described above.
[0035]
For this reason, even if the outer frame of the core holder is damaged by a large external force such as an impact as described above, a large external force can be prevented from being transmitted as it is to the roll-like object supported by the core support portion. As a result, the roll core or the film wound around the core can be greatly reduced in the risk of breakage or damage.
[0036]
As described above, the packing method according to the present invention includes an intermediate frame provided between the core support portion and the outer frame, and an inner rib provided between the core support portion and the intermediate frame, and the intermediate frame and the outer frame. A pair of core holders arranged so that the outer ribs provided between them are not aligned with each other are arranged at both ends of the roll-like material, and rolls at the core support portions of these core holders Since the packing was carried out by supporting the core of the object, even if a roll-like object packed during transportation falls and a large impact occurs, this shock can be absorbed by the core holder. It has a great effect such that the core or film of the rolled material can be prevented from being broken or damaged.
