Description

【0001】
【発明の属する技術分野】
本発明は薄鋼板を巻回したコイルのような円筒製品の輸送に好適な技術に関する。
【0002】
【従来の技術】
図9は従来のコイルの梱包説明図であり、例えば冷間圧延機若しくは熱間圧延機で圧延した後の薄鋼板は、運搬の便利を考えて巻回する。この巻回したものをコイルと呼称する。図においてコイル101は、運搬に伴なう傷付きや錆の発生を避けるために、防水紙又は防錆紙102で包み、必要に応じてクッション性のある段ボール紙103を被せ、スチールベルトからなる結束ベルト104,104で結束し、コイル101の中心穴にリングアタッチメント105,105を嵌合し、コイル101の外周コーナにアウタリング111,111を被せて、クレーン吊り具を掛けることができるようにする。
【0003】
図10は従来の梱包済コイルの吊り姿勢を示す図であり、クレーン吊り具106の爪107,107をリングアタッチメント105,105に掛けることで、コイル101を吊り、ストックヤードから車両荷台へ、車両荷台から輸送船の船倉へ、又はそれらの逆に移動させることができる。ただし、クレーン吊り具106はある程度変形するため、この変形によってはコイル101の側面にクレーン吊り具106が接触してコイル101の側面の疵をつける虞れはある。
【0004】
以上の説明から明らかなように、防水紙又は防錆紙102で包むことにより、外からコイル101に向う水分を遮断して防錆を図り、段ボール紙103を被せることでコイル101の傷付きを防止することができる図9の梱包法は広く採用されている。
【0005】
【発明が解決しようとする課題】
図11は従来の梱包法の課題を示す図であり、車両や船で需要者の元へ梱包済コイルを運搬したのち、需要者は開梱してコイル101を取出し、裸のコイル101を切断し、曲げ、絞るなどの二次加工を施して、製品化するが、前記開梱の際に、発生する防水紙又は防錆紙102、段ボール紙103、結束ベルト104,104、リングアタッチメント105,105及びアウタリング111,111は需要者にとっては不要物となる。これらの不要物、特に防水紙又は防錆紙102や段ボール紙103はダイオキシンの発生を考えると、簡単には焼却処分をすることはできない。この処分を難しくしているのは丁寧な梱包法を採用したこと基づく。対策としては梱包資材を減らすことが有効となる。
【0006】
そこで、本発明の目的は、コイル等の円筒製品を無梱包に近い状態で輸送することのできる新しい技術を提供することにある。
【0007】
【課題を解決するための手段】
上記目的を達成するために請求項1の輸送方法は、ゴム若しくは樹脂からなる可撓性芯材の両端に面ファスナーを備え、可撓性芯材の上面にフェルトを張り、このフェルトの上にビニールシートまたは耐摩耗性を有する樹脂シートを張り、可撓性芯材の下面に別のフェルトを張ってなるクッション性のあるベルトを複数本準備し、薄鋼板を巻回した金属コイルのような円筒製品に少なくとも2本のベルトを所定ピッチ離した状態で、ビニールシートまたは耐摩耗性を有する樹脂シートが外側となるように少なくとも一回転巻付け、このままで若しくはベルトの巻付けの前又は後に防水または防錆性能を備えたフィルム状の包装資材を被せた状態で、輸送することを特徴とする。
【0008】
面ファスナー同士を貼り合させるためにベルトは、一回転以上、すなわち少なくとも一回転巻付ける。この様なベルトを円筒製品に2本巻付け、このままで若しくは防水または防錆性能を備えたフィルム状の包装資材を被せた状態で、輸送する。ベルトがクッション材となって傷付きの発生を抑える。面ファスナーを備えたベルトは取付け、取外しが自在であり、何度も使用することができるため、実質的に無梱包輸送が達成できるといえる。
なお、クッション性のあるベルトは摩耗により剥離しやすい。そこで、本発明ではベルトの表面に耐摩耗性材、具体的にはビニルシートなどの樹脂シートを被せることで剥離対策を施した。剥離対策を施したので、ベルトは何度も使用することができる。
【0009】
請求項の輸送方法は、円筒製品に中心穴がある場合に、断面が略L字を呈し、その一辺が中心穴に対応する曲率を有し、材料が樹脂で、円弧の中心角が360゜未満であるアタッチメントを、中心穴の両エッジに嵌合し、これらのアタッチメントを介して吊り具で円筒製品を吊ることを特徴とする。
【0010】
コイルの場合は中心穴にアタッチメントを取付け、このアタッチメントに吊り具の爪を掛けることでコイルを吊り上げる。このときに使用するアタッチメントを360゜未満のリングにして、軽量化及びコンパクト化を図る。アタッチメントは繰り返し使用可能であるが、万一割れ等の破損が生じても、材料をリサイクル可能若しくは焼却可能な樹脂にすれば、リサイクル若しくは焼却処理が可能となる。
【0013】
請求項では、防水または防錆性能を備えたフィルム状の包装資材は、円筒製品を包み、輸送中に外からの水分の侵入を防ぐ作用をなす樹脂シート、防水布又は防水紙であることを特徴とする。
樹脂シート、防水布又は防水紙で円筒製品を包むことで、円筒製品の発錆を防止しつつ、輸送することができる。包装資材が、樹脂シート、防水布又は防水紙であれば、容易に回収又は廃却することができる。
【0014】
【発明の実施の形態】
本発明の実施の形態を添付図に基づいて以下に説明する。なお、円筒製品はコイルを例に説明する。また、図面は符号の向きに見るものとする。
図1は本発明に係るベルトの斜視図である。
ベルト10は、ゴム若しくは樹脂からなる可撓性芯材11の上下にフェルト12,13を張り、一方のフェルト13にビニルシート14を貼りあわせたものである。フェルト12,13は文字通り厚手の毛布様のものであり、摩耗により表面が剥離しやすい。そこで、フェルト13にビニルシート14を被せて剥離対策とした。例えば、ビニルシート14は、耐摩耗性を有する他の樹脂シートに置き換えることは差支えない。
【0015】
そして、ベルト10の一端(図右端)ではフェルト12及び可撓性芯材11を切欠いて剥き出しになったフェルト13(図では上面)に第1面ファスナー16を貼り付ける。加えて、ベルト10の他端(図左端)ではフェルト13を切欠いて剥き出しになった可撓性芯材11(図では下面)に第2面ファスナー17を貼り付ける。
【0016】
ベルト10は、両端に面ファスナー16,17を備えたクッション性のある帯であるといえる。第1・第2面ファスナー16,17の長さL1,L2の決め方は後述する。
【0017】
図2は本発明に係るアタッチメントの斜視図であり、アタッチメント20は、材料が樹脂で、半割円筒部21と鍔部22とからなり、円弧の中心角がほぼ180゜のいわゆる半円アタッチメントである。また、半割円筒部21の外径曲率は後述するコイルの中心穴の曲率に合致させる。なお、アタッチメント20の中心角はほぼ180゜に限定すること無く、360゜未満であれば角度は任意である。
【0018】
図3は図2の断面図である。
(a)は図2の3a断面を示し、円筒部21の厚さをt21、鍔22の厚さをt22とすれば、鍔22の厚さt22がt21より十分に大きいことを示す。
(b)は図2の3b断面を示し、鍔22は縦リブ22a及び横リブ22bを縦横に渡す(図2も参照)ことにより、肉抜きを図り、鍔22の軽量化を図りつつ剛性を確保する構造にした。
【0019】
図4は本発明に係るアタッチメントの作用図であり、コイル24の中心穴25にアタッチメント20を嵌め、クレーン吊り具26の爪27を掛けた状態を示す。すなわち、クレーン吊り具26によるコイル24の側面及び内周面における傷付きをアタッチメント20で防止する。この図から、クレーン吊り具26の爪27を掛けるためだけなら、全周リングは不要であることが分かる。
加えて、コイル24の側面からクレーン吊り具26までの隙間が鍔の厚さt22で制限され、この厚さt22が十分に大きいので、クレーン吊り具26が仮に変形してもコイル24に接触する心配はない。
【0020】
以上に述べたベルト10及びアタッチメント20の作用を次に説明する。
図4において、一般にコイル24はコイラーと称する巻取り機(図示せず)で巻取るが、巻取り機の巻芯(図示せず)の外径でコイルの中心穴25の径が決まり、コイル24の外径は巻数を増減することで決まる。
【0021】
図5(a),(b)は最大径のコイルの為のベルトを巻付け要領図であり、(a)はコイル正面図、(b)は側面断面である。
先ず径Diが一定である中心穴25の両エッジに、円弧の中心角θが360゜未満で且つ断面がL字を呈するアタッチメント20,20を嵌める。
(a)に示す通りに、アタッチメント20はその両端23,23が中心穴25に引っ掛かるため、下がる心配はない。ただし、樹脂成形の場合は中心角θは自由に選択できるので、中心角θを360゜未満から選択することもできる。
【0022】
次に、外径が最大径Dmaxであるコイル24にベルト10を一回転強巻付け、小さなラップ代Lap1にて、第1面ファスナー16に第2面ファスナー17を接合する。このことから、ベルト10の全長は、(π×Dmax+2×Lap1)で定まる。ただし、ラップ代Lap1はベルト10の幅以上とする。
なお、(b)に示す通りに、ベルト10,10はコイル24の幅に応じて所定ピッチPで2本掛ける。コイル24の幅に応じて3本以上のベルト10を巻き付けることは差支えない。
【0023】
図6(a),(b)は最小径のコイルの為のベルトを巻付け要領図であり、(a)はコイル正面図、(b)は側面断面である。
外径が最小径Dminであるコイル24にベルト10を一回転強巻付け、大きなラップ代Lap2にて、第1面ファスナー16に第2面ファスナー17を接合する。
ベルト10の全長は上述した通りである。そして、図から明らかなように第1面ファスナー16の長さL1、第2面ファスナー17の長さL2共に、ラップ代Lap2より若干長めに設定すればよい。
この結果、ベルト10は最小径から最大径までのコイル24の全てに適用することができる。
【0024】
図7(a)〜(f)は本発明の輸送方法の説明図である。
(a)は裸のコイル24を示す。
(b)にて、コイル24にベルト10,10(奥のベルトは不図示)を巻き、且つアタッチメント20,20(奥のリングは不図示)を嵌める。
(c)にて、アタッチメント20,20に爪27,27(奥の爪は不図示)を掛けつつ、クレーン吊り具26でコイル24を吊り、(d)の車両28の荷物室29に投入する。荷物室29は密閉性のある幌又はパネルで構成するとよい。
【0025】
(d)では、ベルト10・・・(・・・は複数を示す。)のクッション作用で、コイル24・・・に傷が付く心配はない。
そして、(e)に示す船倉31にコイル24・・・を移載する。二段積みしてもベルト10・・・のクッション作用で、コイル24・・・に傷が付く心配はない。
(f)は、需要者に手渡す段階での開梱状態を示す、ベルト10,10及びアタッチメント20,20は矢印▲1▼のごとく、(b)へ戻して再使用する。
なお、船倉31を用いずに、車両28のみ(含む積み替え)で需要者まで運ぶことは差支えなく、このときには矢印▲2▼の如く(d)から(f)へ進める。
【0026】
以上の説明は、コイル24を裸のままで運搬、輸送したが、(a)又は(b)の段階で防水または防錆性能を備えたフィルム状の包装資材(例えば樹脂シート、防水布又は防水紙)(樹脂シートであれば例えば、ポリエチレンシート、特に炭酸カルシウム30%入りポリエチレンシートなら焼却に好適)で、包むことは差支えない。回収、処分ともに極めて容易であるからである。
【0027】
以上をまとめると、両端に面ファスナーを備え、かつ表面に耐摩耗性材を被せたクッション性のあるベルト10を複数本(実施例では2本)準備し、薄鋼板を巻回したコイル24に少なくとも2本のベルト10,10を所定ピッチ離した状態で少なくとも一回転巻付け、このまま(裸のまま)で若しくはベルト10,10の巻付けの前又は後に防水または防錆性能を備えたフィルム状の包装資材(例えば樹脂シート、防水布又は防水紙)を被せた状態で、輸送することを特徴とする。
この輸送方法により、梱包資材の処分をする必要が実質的になくなり、この結果、環境にやさしい輸送方法が達成できる。
【0028】
図8は本発明に係る発錆対策の説明図であり、船倉31又は車両の荷物室29に、空気供給管32を通じて、除湿空気を吹込むことで、コイル24・・・を囲う空気を除湿状態に保つことで、防錆を図る。
具体的には、吸湿剤を十分含浸させたハニカムロータ33をドラムケース34に回転自在に収納し、このドラムケース34からハニカムロータ33の極く近傍まで延ばしたセパレータ35でドラムケース34を図面左右に区分し、ドラムケース34の左半分に第1口36及び第2口37を対向して設け、ドラムケース34の右半分に第3口38及び第4口39を対向して設ける。40はモータである。以上の構成からなるものがハニカムロータ式除湿装置41である。
【0029】
上記ハニカムロータ式除湿装置41を、船倉31又は車両の荷物室29の所定場所に設置し、第1口36から空気供給管32を延ばし、空気供給管32の先を、コイル24・・・を囲う蚊張状の密閉テント(又は遮蔽テント若しくはシート)42内まで延ばす。又、密閉テント(又は遮蔽テント若しくはシート)42内から空気排出管43を延ばし、その先端を第2口37に接続する。そして、空気供給管32(又は空気排出管43)にブロア44を介設すれば、空気を矢印の通りに循環させることができる。
【0030】
また、外気を取入れる外気取入れ管45にヒータ46を取付けるとともに第3口38に接続し、第4口39から湿り空気排出管47を屋外へ延ばす。この湿り空気排出管47にもブロア48を介設する。
【0031】
ハニカムロータ式除湿装置41の作用は次の通りである。
ハニカムロータ33は吸取り紙の様な役割を果たし、空気から水分を除去する。すなわち、空気排出管43で第2口37からドラムケース34に流入した湿った空気は、ハニカムロータ33の除湿作用により除湿空気に変わる。この除湿空気が、空気供給管32を通じて密閉テント42内に至ることになる。
【0032】
この間、ハニカムロータ33はモータ40の作用で所定の速度で回り、第3口38〜第4口39間に至る。この第3口38からハニカムロータ33へヒータ46で温めた加熱空気が流れ、この加熱空気がキャリアとなってハニカムロータ33の水分を除去する。この行為を再生という。乾いたハニカムロータ33が第1口36〜第2口37間へ移動することは言うまでもない。ハニカムロータ33から水分を奪って十分に湿った空気は湿り空気排出管47を介して外へ出る。
従って、密閉テント42の内部は乾いた空気で満たすことができ、発錆を抑えることができる。
【0033】
なお、船倉31若しくは車両の荷物室29を対象にハニカムロータ式除湿装置41で除湿空気を供給することは差支えない。しかし、船倉31若しくは車両の荷物室29の空間体積に比較してコイル24・・・の体積の占める割合が小さいときにはコイル24・・・を密閉テント42で囲い、この密閉テント42へ除湿空気を送れば、ブロア44,48やヒータ46の消費電力が節約できるので好ましい。
【0034】
尚、円筒製品はドラム缶状の容器、中径・大径鋼管であってもよく、要は円筒形状を呈する製品であれば種類は問わない。
また、除湿空気を供給する機器は、上述したものの他、電熱ヒータ、ガス焚ヒータ、油焚ヒータを熱源としたドライヤーであってもよい。
【0035】
【発明の効果】
本発明は上記構成により次の効果を発揮する。
請求項1の輸送方法では、特に、芯材の両端に面ファスナーを備え、芯材の上面にフェルトを張り、このフェルトの上に耐摩耗性材を張り、芯材の下面にフェルトを張ってなるクッション性のあるベルトを採用した。そして、耐摩耗性材が外側になるようにしてベルトを円筒製品に巻付ける。すなわち、芯材の下面に張ったフェルトを円筒製品に接触させ、芯材の上面側に設けた耐摩耗性材を外側に向ける。
円筒製品に下面側のフェルトを接触させることで、円筒製品の傷つきを防ぐことができる。また、フェルトは柔らかいため外力を受けると簡単に摩耗する。そこで、上面側のフェルトを耐摩耗性材で保護するようにした。
すなわち、耐摩耗性材で上面側のフェルトを保護するためベルトの寿命を延ばすことができると共に、下面側のフェルトで円筒製品を保護することができる。
以上の内容を含む請求項1の輸送方法によれば、実質的に裸の円筒製品に、表面に耐摩耗性材を被せたクッション性のある2本又は3本以上のベルトを巻付けるだけで、輸送するものである。従来、必須とされた防水紙やクッション性段ボール紙などからなる梱包資材は不要となる。加えて、ベルトに面ファスナーを備えることで、円筒製品から取外し自在であり、何度も使用することができるため、実質的に無梱包輸送が達成できるといえる。
上述したとおり、クッション性のあるベルトは摩耗により剥離しやすい。そこで、本発明ではベルトの表面に耐摩耗性材を被せることで剥離対策を施した。剥離対策を施したので、ベルトは何度も使用することができる。
請求項1の輸送方法により、梱包資材の処分をする必要が実質的になくなり、この結果、環境にやさしい輸送方法が達成できる。
【0036】
請求項の輸送方法は、円筒製品がコイルなどの場合は中心穴にアタッチメントを取付け、このアタッチメントに吊り具の爪を掛けることでコイルを吊り上げるが、このときに使用するアタッチメントを360゜未満のリングにして、軽量化及びコンパクト化を図る。アタッチメントは繰り返し使用可能であるが、万一割れ等の破損が生じても、材料をリサイクル可能若しくは焼却可能な樹脂にすれば、リサイクル若しくは焼却処理が可能となる。
【0039】
請求項では、防水または防錆性能を備えたフィルム状の包装資材で円筒製品を包み、輸送中に外からの水分の侵入を防ぐ作用をなす樹脂シート、防水布又は防水紙とした。樹脂シート、防水布又は防水紙で円筒製品を包むことで、円筒製品の発錆を防止しつつ、輸送することができる。そして、包装資材が、樹脂シート、防水布又は防水紙であれば、容易に回収又は廃却することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a technique suitable for transporting a cylindrical product such as a coil wound with a thin steel plate.
[0002]
[Prior art]
FIG. 9 is an explanatory view of packing of a conventional coil. For example, a thin steel sheet after being rolled by a cold rolling mill or a hot rolling mill is wound in consideration of convenience of transportation. This wound is called a coil. In the figure, a coil 101 is wrapped with waterproof paper or rust-proof paper 102 and covered with a corrugated cardboard paper 103 with cushioning as necessary in order to avoid the occurrence of scratches and rust caused by transportation. Bundling with binding belts 104, 104, ring attachments 105, 105 are fitted in the center hole of the coil 101, outer rings 111, 111 are put on the outer corners of the coil 101, and a crane suspension can be hung. To do.
[0003]
FIG. 10 is a diagram showing a conventional hanging posture of a packed coil. By hooking claws 107 and 107 of a crane lifting tool 106 on ring attachments 105 and 105, the coil 101 is suspended, and the vehicle is moved from the stock yard to the vehicle loading platform. It can be moved from the carrier to the hold of the transport ship or vice versa. However, since the crane suspension 106 is deformed to some extent, there is a possibility that the crane suspension 106 contacts the side surface of the coil 101 and the side surface of the coil 101 is wrinkled due to this deformation.
[0004]
As is clear from the above description, wrapping with waterproof paper or rust preventive paper 102 blocks moisture from the outside toward the coil 101 to prevent rust, and covers the corrugated cardboard paper 103 to damage the coil 101. The packing method of FIG. 9 that can be prevented is widely adopted.
[0005]
[Problems to be solved by the invention]
FIG. 11 is a diagram showing a problem of the conventional packing method. After the packaged coil is transported to the customer by a vehicle or a ship, the customer unpacks, takes out the coil 101, and cuts the bare coil 101. Then, it is subjected to secondary processing such as bending and squeezing to produce a product. When the unpacking is performed, waterproof paper or rust-proof paper 102, corrugated paper 103, binding belts 104 and 104, ring attachment 105, 105 and the outer rings 111 and 111 are unnecessary for the consumer. These unnecessary items, especially waterproof paper or rustproof paper 102 and corrugated paper 103, cannot easily be incinerated in view of the generation of dioxins. This disposal is made difficult by adopting a careful packing method. As a countermeasure, reducing packaging materials is effective.
[0006]
Therefore, an object of the present invention is to provide a new technology that can transport a cylindrical product such as a coil in a state close to no packaging.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the transportation method according to claim 1 is provided with a hook-and-loop fastener on both ends of a flexible core material made of rubber or resin , and a felt is stretched on the upper surface of the flexible core material. Like a metal coil in which a plurality of cushioning belts are prepared by placing a vinyl sheet or a wear-resistant resin sheet, and another felt on the lower surface of the flexible core , and winding a thin steel plate At least two belts are wound around a cylindrical product at a predetermined pitch, and the plastic sheet is wound at least once so that the vinyl sheet or the abrasion-resistant resin sheet is on the outside, and is waterproofed before or after winding the belt. or in a state covered with the film-like packaging material having a rust-preventive performance, characterized in that transport.
[0008]
In order to bond the surface fasteners, the belt is wound at least once, that is, at least once. Two such belts are wrapped around a cylindrical product, and transported as it is or covered with a film-like packaging material having waterproof or rust prevention performance. The belt acts as a cushioning material to prevent scratches. Since the belt provided with the hook-and-loop fastener can be freely attached and detached and can be used many times, it can be said that substantially unpacked transportation can be achieved.
Note that a belt having cushioning properties is easily peeled off due to wear. Therefore, in the present invention, the belt surface is covered with a wear-resistant material, specifically a resin sheet such as a vinyl sheet, to take measures against peeling. The belt can be used over and over again as a countermeasure against peeling.
[0009]
In the transportation method according to claim 2 , when the cylindrical product has a center hole, the cross section has a substantially L shape, one side thereof has a curvature corresponding to the center hole, the material is resin, and the center angle of the arc is 360. An attachment that is less than 0 ° is fitted to both edges of the center hole, and the cylindrical product is hung with a lifting tool through these attachments.
[0010]
In the case of a coil, an attachment is attached to the center hole, and the coil is lifted by hanging a hook of a lifting tool on this attachment. The attachment used at this time is a ring of less than 360 ° to reduce weight and size. The attachment can be used repeatedly, but even if breakage such as cracking occurs, if the material is made of a resin that can be recycled or incinerated, it can be recycled or incinerated.
[0013]
In claim 3 , the film-like packaging material having waterproof or rust-proof performance is a resin sheet, waterproof cloth or waterproof paper that wraps a cylindrical product and prevents the entry of moisture from outside during transportation. It is characterized by.
By wrapping the cylindrical product with a resin sheet, waterproof cloth or waterproof paper, the cylindrical product can be transported while preventing rusting. If the packaging material is a resin sheet, waterproof cloth or waterproof paper, it can be easily recovered or discarded.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings. The cylindrical product will be described by taking a coil as an example. The drawings are to be viewed in the direction of the reference numerals.
FIG. 1 is a perspective view of a belt according to the present invention.
The belt 10 is formed by stretching felts 12 and 13 on and under a flexible core 11 made of rubber or resin, and bonding a vinyl sheet 14 to one of the felts 13. The felts 12 and 13 are literally thick blankets, and the surface is easily peeled off due to wear. Therefore, the vinyl sheet 14 was put on the felt 13 to prevent peeling. For example, the vinyl sheet 14 can be replaced with another resin sheet having wear resistance.
[0015]
And the 1st surface fastener 16 is affixed on the felt 13 (upper surface in the figure) which notched the felt 12 and the flexible core material 11 at one end (the right end of the figure) of the belt 10. In addition, the second surface fastener 17 is affixed to the flexible core material 11 (the lower surface in the figure) that is notched off the felt 13 at the other end (the left end in the figure) of the belt 10.
[0016]
It can be said that the belt 10 is a cushioning belt having hook and loop fasteners 16 and 17 at both ends. How to determine the lengths L1 and L2 of the first and second surface fasteners 16 and 17 will be described later.
[0017]
FIG. 2 is a perspective view of an attachment according to the present invention, and the attachment 20 is a so-called semicircular attachment made of a resin, a half cylindrical portion 21 and a flange portion 22 and having an arc center angle of approximately 180 °. is there. Further, the outer diameter curvature of the half cylinder portion 21 is matched with the curvature of the center hole of the coil described later. The central angle of the attachment 20 is not limited to about 180 °, and the angle is arbitrary as long as it is less than 360 °.
[0018]
FIG. 3 is a cross-sectional view of FIG.
(A) shows the 3a cross section of FIG. 2, and when the thickness of the cylindrical portion 21 is t21 and the thickness of the flange 22 is t22, the thickness t22 of the flange 22 is sufficiently larger than t21.
(B) shows the 3b cross section of FIG. 2, and the flange 22 passes the vertical ribs 22a and the horizontal ribs 22b vertically and horizontally (see also FIG. 2), thereby reducing the thickness of the flange 22 while reducing the weight. The structure is secured.
[0019]
FIG. 4 is an operation diagram of the attachment according to the present invention, and shows a state in which the attachment 20 is fitted in the center hole 25 of the coil 24 and the claw 27 of the crane suspension 26 is hung. That is, the attachment 20 prevents the side surface and the inner peripheral surface of the coil 24 from being damaged by the crane lifting tool 26. From this figure, it can be seen that the entire circumference ring is not necessary only to hang the claw 27 of the crane suspension 26.
In addition, the gap from the side surface of the coil 24 to the crane suspension 26 is limited by the thickness t22 of the kite, and since this thickness t22 is sufficiently large, even if the crane suspension 26 is deformed, it contacts the coil 24. Don't worry.
[0020]
Next, the operation of the belt 10 and the attachment 20 described above will be described.
In FIG. 4, the coil 24 is generally wound by a winder (not shown) called a coiler. The outer diameter of the winding core (not shown) of the winder determines the diameter of the central hole 25 of the coil. The outer diameter of 24 is determined by increasing or decreasing the number of turns.
[0021]
5 (a) and 5 (b) are diagrams for winding a belt for a coil having the maximum diameter, (a) is a front view of the coil, and (b) is a side cross-sectional view.
First, attachments 20 and 20 having an arc center angle θ of less than 360 ° and a L-shaped cross section are fitted to both edges of the center hole 25 having a constant diameter Di.
As shown to (a), since the both ends 23 and 23 of the attachment 20 are hooked in the center hole 25, there is no worry of falling. However, since the center angle θ can be freely selected in the case of resin molding, the center angle θ can be selected from less than 360 °.
[0022]
Next, the belt 10 is wound around the coil 24 whose outer diameter is the maximum diameter Dmax by one turn, and the second surface fastener 17 is joined to the first surface fastener 16 with a small lap allowance Lap1. From this, the total length of the belt 10 is determined by (π × Dmax + 2 × Lap1). However, the lap margin Lap1 is equal to or greater than the width of the belt 10.
As shown in (b), two belts 10 and 10 are hung at a predetermined pitch P according to the width of the coil 24. Depending on the width of the coil 24, three or more belts 10 may be wound.
[0023]
6 (a) and 6 (b) are diagrams for winding a belt for a coil having a minimum diameter, (a) is a front view of the coil, and (b) is a side cross-sectional view.
The belt 10 is wound around the coil 24 whose outer diameter is the minimum diameter Dmin once, and the second surface fastener 17 is joined to the first surface fastener 16 at a large lap allowance Lap2.
The overall length of the belt 10 is as described above. As is apparent from the drawing, the length L1 of the first surface fastener 16 and the length L2 of the second surface fastener 17 may be set slightly longer than the lap allowance Lap2.
As a result, the belt 10 can be applied to all the coils 24 from the minimum diameter to the maximum diameter.
[0024]
7 (a) to 7 (f) are explanatory diagrams of the transportation method of the present invention.
(A) shows the bare coil 24.
At (b), the belts 10 and 10 (the back belt is not shown) are wound around the coil 24, and the attachments 20 and 20 (the back ring is not shown) are fitted.
At (c), the claws 27 and 27 (the back nails are not shown) are hung on the attachments 20 and 20 while the coil 24 is hung by the crane lifting device 26 and put into the luggage compartment 29 of the vehicle 28 of (d). . The luggage compartment 29 may be composed of a sealed hood or panel.
[0025]
In (d), there is no fear that the coils 24... Will be damaged by the cushioning action of the belts 10.
And coil 24 ... is transferred to the hold 31 shown to (e). Even if two stages are stacked, there is no concern that the coils 24...
(F) shows the unpacking state at the stage of handing to the consumer. The belts 10 and 10 and the attachments 20 and 20 are returned to (b) and reused as indicated by the arrow (1).
It should be noted that it is possible to carry the vehicle only to the vehicle 28 (including transshipment) without using the hold 31, and at this time, proceed from (d) to (f) as indicated by arrow (2).
[0026]
In the above description, the coil 24 is transported and transported in the bare state, but a film-like packaging material (for example, a resin sheet, a waterproof cloth or a waterproofing) having waterproof or rust prevention performance at the stage (a) or (b). Paper) (for example, a polyethylene sheet, especially a polyethylene sheet containing 30% calcium carbonate is suitable for incineration if it is a resin sheet). This is because both recovery and disposal are extremely easy.
[0027]
To summarize the above, a plurality of cushioning belts 10 (two in the embodiment) having hook-and-loop fasteners at both ends and covered with a wear-resistant material on the surface are prepared , and the coil 24 is wound with a thin steel plate. At least two belts 10 and 10 are wound at least once with a predetermined pitch apart, and in this state (as they are bare) or before or after winding of the belts 10 and 10, a film having waterproof or rust prevention performance It is characterized by being transported in a state covered with a packaging material (for example, resin sheet, waterproof cloth or waterproof paper).
This transportation method substantially eliminates the need to dispose of the packing material, and as a result, an environmentally friendly transportation method can be achieved.
[0028]
FIG. 8 is an explanatory diagram of rust prevention measures according to the present invention, and dehumidifying the air surrounding the coils 24... By dehumidifying air through the air supply pipe 32 into the cargo hold 31 or the luggage compartment 29 of the vehicle. Rust prevention is achieved by maintaining the state.
Specifically, a honeycomb rotor 33 sufficiently impregnated with a hygroscopic agent is rotatably accommodated in a drum case 34, and the drum case 34 is left and right in the drawing by a separator 35 extending from the drum case 34 to the very vicinity of the honeycomb rotor 33. The first opening 36 and the second opening 37 are provided facing the left half of the drum case 34, and the third opening 38 and the fourth opening 39 are provided facing the right half of the drum case 34. Reference numeral 40 denotes a motor. The honeycomb rotor type dehumidifier 41 is configured as described above.
[0029]
The honeycomb rotor type dehumidifier 41 is installed at a predetermined location in the cargo hold 31 or the luggage compartment 29 of the vehicle, the air supply pipe 32 is extended from the first port 36, and the tip of the air supply pipe 32 is connected to the coil 24. Extend into the enclosed mosquito-like sealed tent (or shielding tent or sheet) 42. Further, the air discharge pipe 43 is extended from the inside of the sealed tent (or shielding tent or sheet) 42, and the tip thereof is connected to the second port 37. And if the blower 44 is provided in the air supply pipe 32 (or the air discharge pipe 43), air can be circulated as shown by the arrow.
[0030]
In addition, the heater 46 is attached to the outside air intake pipe 45 that takes in outside air, and is connected to the third port 38, and the wet air discharge pipe 47 is extended from the fourth port 39 to the outdoors. This humid air discharge pipe 47 is also provided with a blower 48.
[0031]
The operation of the honeycomb rotor type dehumidifier 41 is as follows.
The honeycomb rotor 33 functions like a blotting paper and removes moisture from the air. That is, the humid air that has flowed into the drum case 34 from the second port 37 in the air discharge pipe 43 is changed to dehumidified air by the dehumidifying action of the honeycomb rotor 33. The dehumidified air reaches the sealed tent 42 through the air supply pipe 32.
[0032]
During this time, the honeycomb rotor 33 rotates at a predetermined speed by the action of the motor 40 and reaches between the third port 38 and the fourth port 39. Heated air heated by the heater 46 flows from the third port 38 to the honeycomb rotor 33, and the heated air serves as a carrier to remove moisture from the honeycomb rotor 33. This act is called reproduction. Needless to say, the dried honeycomb rotor 33 moves between the first port 36 and the second port 37. Air sufficiently moistened after removing moisture from the honeycomb rotor 33 goes out through the humid air discharge pipe 47.
Therefore, the inside of the sealed tent 42 can be filled with dry air, and rusting can be suppressed.
[0033]
Note that dehumidified air may be supplied to the cargo hold 31 or the luggage compartment 29 of the vehicle by the honeycomb rotor type dehumidifier 41. However, when the proportion of the volume of the coils 24 is small compared with the space volume of the hold 31 or the luggage room 29 of the vehicle, the coils 24 are surrounded by the sealed tent 42 and dehumidified air is supplied to the sealed tent 42. If it sends, the power consumption of the blowers 44 and 48 and the heater 46 can be saved, which is preferable.
[0034]
The cylindrical product may be a drum-like container or a medium-diameter or large-diameter steel pipe, and any type may be used as long as the product has a cylindrical shape.
Moreover, the apparatus which supplies dehumidified air may be the dryer which used the electric heat heater, the gas fired heater, and the oil fired heater as a heat source other than what was mentioned above.
[0035]
【The invention's effect】
The present invention exhibits the following effects by the above configuration.
In the transportation method of claim 1, in particular, a hook-and-loop fastener is provided at both ends of the core material, a felt is stretched on the upper surface of the core material, an abrasion-resistant material is stretched on the felt, and a felt is stretched on the lower surface of the core material. Adopted a cushioning belt. Then, the belt is wound around the cylindrical product with the wear-resistant material facing outward. That is, the felt stretched on the lower surface of the core material is brought into contact with the cylindrical product, and the wear-resistant material provided on the upper surface side of the core material is directed outward.
By bringing the felt on the lower surface side into contact with the cylindrical product, it is possible to prevent the cylindrical product from being damaged. Also, because felt is soft, it easily wears when subjected to external forces. Therefore, the felt on the upper surface side was protected with an abrasion resistant material.
That is, since the upper surface side felt is protected by the wear-resistant material, the life of the belt can be extended, and the cylindrical product can be protected by the lower surface side felt.
According to the transportation method of claim 1 including the above contents, it is only necessary to wind two or three or more belts having cushioning properties with a wear-resistant material on the surface of a substantially bare cylindrical product. To be transported. Conventionally, packaging materials made of waterproof paper, cushioning corrugated paper, or the like, which are essential, are unnecessary. In addition, by providing the belt with a hook-and-loop fastener, it can be removed from the cylindrical product and can be used many times, so that it can be said that substantially unpacked transportation can be achieved.
As described above, a cushioned belt is easily peeled off due to wear. Therefore, in the present invention, a countermeasure against peeling is taken by covering the belt surface with a wear-resistant material. The belt can be used over and over again as a countermeasure against peeling.
The method of transport according to claim 1, necessary to dispose of the packaging material is substantially eliminated, as a result, Ru achieved friendly transportation methods environmentally.
[0036]
In the transportation method of claim 2 , when the cylindrical product is a coil or the like, an attachment is attached to the center hole, and the coil is lifted by hooking a hook of a lifting tool on the attachment. The attachment used at this time is less than 360 °. Use a ring to reduce weight and size. The attachment can be used repeatedly, but even if breakage such as cracking occurs, if the material is made of a resin that can be recycled or incinerated, it can be recycled or incinerated.
[0039]
According to the third aspect of the present invention , the cylindrical product is wrapped with a film-like packaging material having waterproof or rust-proof performance, and a resin sheet, waterproof cloth, or waterproof paper that acts to prevent moisture from entering during transportation is used. By wrapping the cylindrical product with a resin sheet, waterproof cloth or waterproof paper, the cylindrical product can be transported while preventing rusting. And if a packaging material is a resin sheet, a waterproof cloth, or waterproof paper, it can collect | recover or discard easily.
