Description

この発明は、例えば銅管などの長尺状の管を整列巻き且つトラバース巻きによって構成したレベルワウンドコイルの梱包材における緩衝体に関し、特に、ＥＴＴＳ方式で前記管を引き出す際にスムーズに引き出すことのできる緩衝体及び梱包したレベルワウンドコイルの載置方法に関する。   The present invention relates to a shock absorber in a packaging material for a level-wound coil formed by aligning and traversing a long tube such as a copper tube, and in particular, smoothly pulling out the tube in the ETTS method. The present invention relates to a shock absorber and a method for placing a packed level wound coil.

例えば、空調装置等に用いられる銅管等の長尺状の管はコイル状にして搬送する必要があり、従来はボビンに巻き付けていた。この場合、利用者は、ボビンに巻き取られた管を、例えば、アンコイラーのような引き出し装置にボビンごとセットして、所望の長さ分を引き出して使用していた。   For example, a long tube such as a copper tube used in an air conditioner or the like needs to be transported in a coil shape, and has conventionally been wound around a bobbin. In this case, the user has used the tube wound around the bobbin by setting the bobbin together with a pulling device such as an uncoiler and pulling out a desired length.

なお、管をコイル状にする巻取り方法は様々存在する。一般的に、上述のような銅管の場合、ボビンを用いて一方のフランジ側から他方のフランジに向かってボビン軸の外周に管を巻き付けていく。そして、他方のフランジ側に達すると、既に巻き付けた管の外側に乗り上げて、一方側のフランジに向かって２層目を巻き付ける。ここで、層間を跨いで前層から次層を遷移する部分を層遷移部という。これを複数層分繰り返してコイル状を構成する。   There are various winding methods for coiling the tube. In general, in the case of the copper pipe as described above, a pipe is wound around the outer periphery of the bobbin shaft from one flange side to the other flange using a bobbin. And when it reaches the other flange side, it rides on the outer side of the already wound pipe and winds the second layer toward the flange on the one side. Here, a portion where the next layer is transitioned from the previous layer across the layers is referred to as a layer transition portion. This is repeated for a plurality of layers to form a coil shape.

なお、上記巻き付け方法には、ボビン軸の外周をフランジに平行に管を巻き付ける整列巻き、ボビン軸の軸方向に交差する方向で巻き付ける螺旋巻き、次層の管を前層における隣り合う管の間に巻き付けるトラバース巻き等がある。   Note that the winding method includes aligned winding in which the outer periphery of the bobbin shaft is wound in parallel with the flange, spiral winding in which the tube is wound in a direction crossing the axial direction of the bobbin shaft, and the tube in the next layer is placed between adjacent tubes in the previous layer. There are traverse windings that are wound around.

しかし、上述したように、管をボビンに巻き付けた場合、ボビンごとセットする引き出し装置が大きくなるといった問題があった。また、すべての管を使用した後にボビンが残るため、ボビンを処分する必要があった。   However, as described above, when the tube is wound around the bobbin, there is a problem that the pulling device for setting the bobbin becomes large. Moreover, since the bobbin remains after using all the tubes, it was necessary to dispose of the bobbin.

そこで、コイル状にしてからボビンを取り外して梱包し、利用者はボビンが取り外されたコイル体を、コイル状の軸方向が上下方向となるように配置し、コイル状の内周側の管始端から引き出して使用するＥＴＴＳ（Eye to the sky）方式が多く用いられている。   Therefore, after the coil is formed, the bobbin is removed and packed, and the user arranges the coil body from which the bobbin is removed so that the coiled axial direction is the vertical direction, and the coiled inner peripheral pipe start end The ETTS (Eye to the sky) method, which is used by pulling it out from the sky, is often used.

上記ＥＴＴＳ方式は、コイル体の内周側の管始端から平面視中心側に引き出して中央上部に引き出す方法である。このようなＥＴＴＳ方式では管を引き出す際に、コイル体の下面部分が損傷しないよう梱包材の緩衝体を介在させたまま、管を上方に引き出して使用する。
このＥＴＴＳ方式によって管の引き出しを行うと、大規模な引き出し装置を必要とせず、また、ボビンを処分する必要がなく利便性が高い。 The ETTS method is a method of pulling out from the pipe starting end on the inner peripheral side of the coil body to the center side in a plan view and pulling out to the upper center. In such an ETTS system, when pulling out the tube, the tube is pulled out and used with the packing material cushion interposed so that the lower surface portion of the coil body is not damaged.
When the tube is pulled out by this ETTS method, a large-scale drawing device is not required, and it is not necessary to dispose the bobbin, which is highly convenient.

しかし、上述したような層遷移部が引き出し時に引っ掛かってキンクし破損する等の問題があった。
上記問題について詳しく説明すると、上述したような管の巻き付け方法により、層遷移部は層ごとにコイル体の上面及び下面に交互に生じる。 However, there has been a problem that the layer transition portion as described above is caught when pulled out and is kinked and damaged.
The above problem will be described in detail. The layer transition portions are alternately generated on the upper surface and the lower surface of the coil body for each layer by the above-described tube winding method.

例えば、コイル体の内周側の管始端が内周側1層目の上端部にあった場合、管は内周側1層目の下端部で内周側２層目に遷移する。反対に、内周側２層目の上端部で内周側３層目へ遷移する。このように、層遷移部は、奇数層から偶数層への層遷移部と、偶数層から奇数層への層遷移部とは、コイル体の上下面に交互に生じる。   For example, when the tube start end on the inner peripheral side of the coil body is at the upper end of the first inner layer, the tube transitions to the second inner layer at the lower end of the first inner layer. On the other hand, the transition is made to the inner peripheral side third layer at the upper end of the inner peripheral side second layer. As described above, the layer transition portion is alternately formed on the upper and lower surfaces of the coil body from the odd-numbered layer to the even-numbered layer transition portion and the even-numbered layer to the odd-numbered layer transition portion.

そして、上記ＥＴＴＳ方式において、上述したようなコイル体の下面側の層遷移部を引き出す際、まだ引き出されていない次層の管が層遷移部の上方に残っているため、上方の管と上記緩衝体との間に層遷移部が挟まれた状態で引っ張られ、その負荷によって層遷移部がキンクして破損するといった問題があった。   And in the ETTS system, when the layer transition part on the lower surface side of the coil body as described above is pulled out, the tube of the next layer that has not yet been pulled out remains above the layer transition part. There is a problem that the layer transition part is pulled between the buffer body and the layer transition part is kinked and damaged by the load.

そこで、特許文献１では、レベルワウンドコイルを構成する管の巻き方によって、下面側の層遷移部が上記緩衝体に当接しないレベルワウンドコイルを構成することを提案している。   Therefore, Patent Document 1 proposes that a level-wound coil in which a lower layer-side layer transition portion does not come into contact with the buffer body is formed by winding a pipe constituting the level-wound coil.

詳しくは、管を整列巻きするとともに、例えば奇数層の最下段とその隣の管との間に偶数層の最下段の管を巻き付けるトラバース巻きによってレベルワウンドコイルを構成する。これにより、奇数層から偶数層への下面側に生じる層遷移部と上記緩衝体との間に隙間が生じ、下面側の層遷移部が引き出される際にキンクなどによる破損を防止することができるとされている。   Specifically, the level wound coil is formed by traverse winding in which the tubes are aligned and wound, for example, the lowermost tube of the even number layer is wound between the lowermost step of the odd layer and the adjacent tube. As a result, a gap is generated between the buffer layer and the layer transition portion generated on the lower surface side from the odd layer to the even layer, and damage due to kinks or the like can be prevented when the layer transition portion on the lower surface side is pulled out. It is said that.

特開２００２−３７０８６９号公報JP 2002-370869 A

しかし、現実的には、連続する管が層間を跨いで遷移する層遷移部は、例えば、奇数層の最下段から偶数層である次層に遷移するため、最下段で次層に遷移する層遷移部の一部は、上方の管と上記緩衝体とによって挟まれた状態となり、層遷移部の破損を確実に防止できる方法ではなかった。   However, in reality, the layer transition part where a continuous tube transitions between layers transitions from the lowest layer of the odd layer to the next layer that is the even layer, for example, so that the layer transitions to the next layer at the bottom layer. A part of the transition part is sandwiched between the upper tube and the buffer body, and it is not a method that can reliably prevent the layer transition part from being damaged.

そこで、本発明は、コイル状の管をＥＴＴＳ方式で引き出す際に、最下段の層遷移部が緩衝体との間に挟まれて破損することを防止できる緩衝体及び梱包されたレベルワウンドコイルの載置方法を提供することを目的とする。   Therefore, the present invention provides a shock absorber that can prevent the bottom layer transition portion from being sandwiched between the shock absorber and being damaged when the coiled tube is drawn out by the ETTS method. It aims at providing the mounting method.

It means that it is a packaging material to be configured.

It can be constituted by a buffer made of plastic corrugated board, a buffer formed of a resin plate, a buffer formed of a foamed resin plate, or a buffer formed of a wooden plate.

上記摩擦低減手段とは、摩擦低減手段を備えない場合に緩衝体と層遷移部との間で生じる摩擦より低下させる手段であり、当接させないことで摩擦の発生を防止して摩擦低減手段を備えない場合に生じる摩擦より低減させる低減手段である。 The friction reducing means is a means for lowering the friction generated between the buffer and the layer transition portion when the friction reducing means is not provided. It is a reduction means for reducing the friction generated when not provided .

上記位置明示手段は、色によって凹部の位置を明示する位置明示手段、マーク等の記号によって凹部の位置を明示する位置明示手段とすることができるとともに、位置明示手段を、緩衝体のレベルワウンドコイルに当接する側の面及び反対側の面の少なくとも一方に備えることができる。   The position specifying means can be a position specifying means for specifying the position of the recess by color, or a position specifying means for specifying the position of the recess by a symbol such as a mark. Can be provided on at least one of the surface on the abutting side and the surface on the opposite side.

上記当接方向明示手段は、例えば、レベルワウンドコイルを構成する管の始端位置や終端位置に対する緩衝体を当接させる回転位置を明示する手段とすることができる。   The abutting direction specifying means can be, for example, a means for clearly indicating the rotational position where the buffer body is brought into contact with the start end position and the end position of the pipe constituting the level wound coil.

具体的な態様として、マーク等の記号によって始端位置の位置を明示する位置明示手段とすることができ、さらに、当接方向明示手段を上記位置明示手段と兼ねることもできる。   As a specific mode, it is possible to use position specifying means for clearly indicating the position of the starting end position by a symbol such as a mark, and further, the contact direction specifying means can also serve as the position specifying means.

なお、連続する管を整列巻き且つトラバース巻きによって径方向に複数層巻き回してコイル状に構成したレベルワウンドコイルを梱包する梱包材のうちコイル端面に当接させる緩衝体であって、前記レベルワウンドコイルの層間を跨いで次層に遷移する前記管の層遷移部に対向する箇所に、該層遷移部との摩擦を低減する摩擦低減手段を備えたことにより、レベルワウンドコイルを梱包した状態で下面を保護しながら、管を破損させるとなく、ＥＴＴＳ方式によって管を確実に引き出すことができる。   In addition, the level wound is a shock absorber that contacts a coil end surface of a packing material for packing a level wound coil configured in a coil shape by winding a plurality of layers in a radial direction by aligned winding and traverse winding. In a state where the level-wound coil is packaged by providing a friction reducing means for reducing friction with the layer transition portion at a location facing the layer transition portion of the tube that transitions to the next layer across the layers of the coil. The tube can be reliably pulled out by the ETTS method without damaging the tube while protecting the lower surface.

詳しくは、緩衝体における層遷移部に対向する箇所に、該層遷移部との摩擦を低減する摩擦低減手段を備えたことにより、引き出されていない管が上方に残っている下面側の層遷移部を、緩衝体とレベルワウンドコイル下面とが当接する状態で引っ張っても、摩擦低減手段によって緩衝体と層遷移部との摩擦が低減され、引っ張り負荷によって層遷移部がキンクして破損することを防止できる。   Specifically, the layer transition on the lower surface side where the pipe that is not drawn out remains above is provided by providing a friction reducing means that reduces friction with the layer transition part at a location facing the layer transition part in the buffer body. Even if the part is pulled in a state where the shock absorber and the lower surface of the level wound coil are in contact with each other, the friction between the shock absorber and the layer transition part is reduced by the friction reducing means, and the layer transition part is kinked and damaged by the tensile load. Can be prevented.

例えば、緩衝体におけるコイルに当接する側の面に形成した凹部による摩擦低減手段で構成した場合、層遷移部が上方の管と、緩衝体の面との間に挟まれないため、破損することなく管を確実に引き出すことができる。   For example, when it is configured with friction reducing means by a recess formed on the surface of the buffer body that contacts the coil, the layer transition portion is not sandwiched between the upper tube and the surface of the buffer body, so that it is damaged. The tube can be pulled out reliably.

このように、レベルワウンドコイルを梱包する梱包材のうちコイル端面に当接させる緩衝体における層遷移部に対向する箇所に、該層遷移部との摩擦を低減する摩擦低減手段を備えたことによって、引き出されていない管が上方に残っている下面側の層遷移部を、緩衝体とレベルワウンドコイル下面とが当接する状態で引っ張っても、緩衝体と層遷移部との摩擦が低減され、破損することなく管を確実に引き出すことができる緩衝体を構成することができる。   Thus, by providing the friction reducing means for reducing the friction with the layer transition portion at the location facing the layer transition portion in the shock absorber to be brought into contact with the coil end surface of the packing material for packing the level wound coil. Even if the lower layer side transition portion where the pipe that has not been pulled out remains is pulled in a state where the buffer body and the lower surface of the level wound coil are in contact with each other, the friction between the buffer body and the layer transition portion is reduced, A buffer body that can reliably pull out the tube without being damaged can be configured.

また、前記摩擦低減手段を、前記コイル端面に当接する面に形成した凹部で構成することによって、容易に凹状の摩擦低減手段を構成して、ＥＴＴＳ方式において損傷することなく管を確実に引き出せる緩衝体を得ることができる。   Further, the friction reducing means is constituted by a concave portion formed on the surface abutting against the coil end face, so that a concave friction reducing means can be easily formed to buffer the pipe without damage in the ETTS system. You can get a body.

また、前記凹部の位置を明示する位置明示手段を備えたことにより、緩衝体における摩擦低減手段である凹部の位置を容易に確認することができる。
詳しくは、位置明示手段を、緩衝体のレベルワウンドコイルに当接する側の面に備えた場合、凹部の位置を容易に確認しながら緩衝体を用いてレベルワウンドコイルを梱包することができる。 Further, by providing the position specifying means for clearly indicating the position of the concave portion, the position of the concave portion which is a friction reducing means in the buffer body can be easily confirmed.
Specifically, when the position indication means is provided on the surface of the shock absorber that is in contact with the level wound coil, the level wound coil can be packed using the shock absorber while easily confirming the position of the recess.

また、緩衝体のレベルワウンドコイルに当接する側と反対側の面に位置明示手段を備えた場合、梱包後の外部から凹部の位置を容易に確認することができる。したがって、緩衝体に備えた凹部の位置を確認しながら梱包されたレベルワウンドコイルを搬送等において取り扱うことができ、利便性が向上する。   Moreover, when the position indication means is provided on the surface opposite to the side in contact with the level wound coil of the buffer body, the position of the recess can be easily confirmed from the outside after packing. Therefore, the level wound coil packed while confirming the position of the recessed part provided in the buffer can be handled in transportation and the convenience is improved.

また、前記コイル端面に当接させる向きを明示する当接方向明示手段を備えたことにより、摩擦低減手段を層遷移部に対向する位置に配置した状態で緩衝体をレベルワウンドコイルに当接させて梱包することができる。したがって、ＥＴＴＳ方式で破損することなく管を確実に引き出すことができる。   Further, by providing a contact direction indicating means for clearly indicating the direction of contact with the coil end face, the shock absorber is brought into contact with the level-wound coil in a state where the friction reducing means is disposed at a position facing the layer transition portion. Can be packed. Therefore, the pipe can be reliably pulled out without being damaged by the ETTS method.

また、前記管の整列方向が上下方向となるよう配置した前記レベルワウンドコイルにおける少なくとも下側の前記コイル端面に、上述の緩衝体を当接させて梱包するレベルワウンドコイルの梱包方法としたことで、レベルワウンドコイルの下面側に緩衝体を介在させたまま、ＥＴＴＳ方式によって、破損することなく管を確実に引き出すことができるため、利便性が向上する。   Further, the level wound coil is packed by bringing the above-mentioned buffer into contact with at least the lower coil end surface of the level wound coil arranged so that the tube is aligned in the vertical direction. Since the pipe can be reliably pulled out without being damaged by the ETTS method with the buffer provided on the lower surface side of the level wound coil, the convenience is improved.

さらにまた、連続する管を整列巻き且つトラバース巻きによって径方向に複数層巻き回してコイル状に構成したレベルワウンドコイルを梱包し、前記管の整列方向が上下方向となるよう配置して上下方向に積み重ねるレベルワウンドコイルの載置方法であって、前記レベルワウンドコイルを梱包する梱包材のうちコイル端面に当接させる緩衝体の当接面における、層間を跨いで次層に遷移する前記管の層遷移部に対向する箇所に凹部を形成し、該緩衝体に、前記凹部の位置を明示する位置明示手段を備え、前記レベルワウンドコイルにおける少なくとも下側の前記コイル端面に、上記緩衝体を当接させて前記レベルワウンドコイルを梱包し、上下方向に重ね合う梱包された前記レベルワウンドコイルの前記緩衝体の前記凹部の配置が、前記レベルワウンドコイルを積み重ねる上下方向の軸に対して軸対照となるよう積み重ねたことにより、レベルワウンドコイルを載置したまま、ＥＴＴＳ方式によって、破損することなく管を確実に引き出すことができる。   Further, the level wound coil is formed by winding a plurality of layers in the radial direction by arranging and winding a continuous tube in a radial direction, and packing the level wound coil. The tube is arranged so that the alignment direction of the tubes is in the vertical direction. A method of placing level wound coils to be stacked, wherein the tube layer transitions to the next layer across the layers on the abutting surface of the buffer body that abuts against the coil end surface of the packing material for packing the level wound coil. A concave portion is formed at a position facing the transition portion, the buffer body is provided with a position specifying means for clearly indicating the position of the concave portion, and the buffer body is brought into contact with at least the lower coil end surface of the level wound coil. The level-wound coil is packaged, and the concave portion of the buffer body of the packaged level-wound coil that overlaps in the vertical direction is By stacked so that the axis control with respect to the vertical axis stacking Ruwaundokoiru, while placing the level-wound coils, by ETTS method, the tube can be reliably elicit without breaking.

具体的には、上下に積み重ねたレベルワウンドコイルのうち最上段のレベルワウンドコイルを、下面側を緩衝体で保護したまま、ＥＴＴＳ方式において、破損することなく管を確実に引き出すことができる。   Specifically, in the ETTS method, the tube can be reliably pulled out without being damaged in the ETTS system while the uppermost level wound coil among the level wound coils stacked vertically is protected by the buffer.

また、緩衝体の凹部の配置が、上下方向の軸に対して軸対照となるよう前記レベルワウンドコイルを積み重ねているため、凹部が同方向に配置された状態で積み重ねた場合に生じる傾きを防止することができる。   In addition, since the level wound coils are stacked so that the positions of the recesses of the buffer body are aligned with respect to the axis in the vertical direction, the tilt that occurs when the recesses are stacked in the same direction is prevented. can do.

また、凹部の位置を明示する位置明示手段を緩衝体に備えたことにより、容易に凹部の位置を確認して、緩衝体の凹部の配置が軸対照となるようレベルワウンドコイルを積み重ねることができる。   In addition, since the buffer body is provided with a position specifying means for clearly indicating the position of the concave portion, the position of the concave portion can be easily confirmed, and the level wound coils can be stacked so that the arrangement of the concave portion of the buffer body becomes an axis contrast. .

帯状ビニールカバー２１は、図３に示すように、ＬＷＣ１０の高さより一回り幅広の帯状であり、ＬＷＣ１０の外周面に巻きつけてカバーする帯状ビニールカバーである。 The packing material 20 is composed of a belt-shaped vinyl cover 21 made of a strip-shaped transparent vinyl and a lower-surface buffer plate 30 to be brought into contact with the coil lower surface 11b.
As shown in FIG. 3, the strip-shaped vinyl cover 21 is a strip-shaped vinyl cover that is slightly wider than the height of the LWC 10 and is wrapped around the outer peripheral surface of the LWC 10 to cover it.

下面緩衝プレート３０は、軽量で緩衝性を備えながら剛性もあり、耐熱性・耐水性・耐薬品性・その他各種の機械的特性に優れた無架橋低発泡ポリプロピレンシート製の板状体を、ＬＷＣ１０の径より一回り大きな円形状に形成している。   The lower buffer plate 30 is a lightweight and cushioning yet rigid plate-like body made of a non-crosslinked low-foamed polypropylene sheet having excellent heat resistance, water resistance, chemical resistance, and other various mechanical properties. It is formed in a circular shape that is slightly larger than the diameter.

下面緩衝プレート３０は、図５に示すように、最下層を構成する円形台座板３１と、該円形台座板３１と同外径の扇型に形成された扇状台座板３２と、扇状台座板３２に上面に貼り付ける凹部形成板３３とを貼り付けた３層構造で構成している。   As shown in FIG. 5, the lower buffer plate 30 includes a circular pedestal plate 31 constituting the lowermost layer, a fan-shaped pedestal plate 32 formed in a fan shape having the same outer diameter as the circular pedestal plate 31, and a fan-shaped pedestal plate 32. It has a three-layer structure in which a recess forming plate 33 attached to the upper surface is attached.

扇型の扇状台座板３２は、外周部をそろえて、４方向に等間隔で円形台座板３１に貼り付けることによって、平面視＋状のバンド溝３４を形成している。
上記扇状台座板３２の上面に貼り付ける凹部形成板３３によって摩擦低減凹部４０を形成している。 The fan-shaped fan-shaped pedestal plate 32 is formed with a band groove 34 having a + shape in plan view by aligning the outer peripheral portion and affixing it to the circular pedestal plate 31 at equal intervals in four directions.
A friction-reducing recess 40 is formed by a recess-forming plate 33 attached to the upper surface of the fan-shaped base plate 32.

詳しくは、図４に示すように、下面緩衝プレート３０を平面視＋状のバンド溝３４で４方向に領域を分断し、右上から順に時計回りに、第１凹部領域、第２凹部領域、第３凹部領域、第４凹部領域に等間隔で設定している。
そして、右上の第１凹部領域において、円形台座板３１と外周が一致する帯円弧状凹部形成板３３ａによって扇状凹部４０ａを構成している。 Specifically, as shown in FIG. 4, the lower buffer plate 30 is divided into four directions by a band groove 34 having a planar view + shape, and the first concave region, the second concave region, The three recessed areas and the fourth recessed areas are set at equal intervals.
And in the 1st recessed part area | region of an upper right, the fan-shaped recessed part 40a is comprised by the band circular arc-shaped recessed part formation board 33a in which outer periphery corresponds with the circular base plate 31. FIG.

右下の第２凹部領域では、扇状凹部４０ａより小さな径の扇状凹部形成板３３ｂａと、第１凹部領域における扇状凹部４０ａの半分程度の幅で形成され、円形台座板３１と外周が一致する帯円弧状凹部形成板３３ｂｂによって小径帯円弧状凹部４０ｂを構成している。   In the lower right second recessed area, the fan-shaped recessed section forming plate 33ba having a smaller diameter than the fan-shaped recessed section 40a and a band that is approximately half the width of the fan-shaped recessed section 40a in the first recessed area and the outer circumference of the circular pedestal plate 31 coincides. The arc-shaped recess forming plate 33bb constitutes the small-diameter band arc-shaped recess 40b.

左下の第３凹部領域では、扇状凹部４０ａと同径の扇状凹部形成板３３ｃａと、円形台座板３１の外周に沿って形成された細い帯円弧状凹部形成板３３ｃｂによって中径帯円弧状凹部４０ｃを構成している。
左上の第４凹部領域では、第２凹部領域における小径帯円弧状凹部４０ｂと同外径の扇状で形成された扇状凹部形成板３３ｄによって大径帯円弧状凹部４０ｄを構成している。 In the lower left third recessed area, the medium-band arc-shaped recess 40c is formed by a fan-shaped recess forming plate 33ca having the same diameter as the fan-shaped recess 40a and a thin band arc-shaped recess forming plate 33cb formed along the outer periphery of the circular base plate 31. Is configured.
In the upper left fourth recess region, the large-diameter arc-shaped recess 40d is formed by a fan-shaped recess forming plate 33d formed in a fan shape having the same outer diameter as the small-diameter arc-shaped recess 40b in the second recess region.

このように、右上から順に時計回りに設定された第１乃至第４凹部領域には、それぞれ径方向の位置が順に外側に移動するように配置される摩擦低減凹部４０が凹部形成板３３によって形成され、各凹部領域の間に平面視＋状のバンド溝３４を形成している。   Thus, in the first to fourth recessed areas set in the clockwise direction from the upper right, the friction reducing recesses 40 are formed by the recessed portion forming plate 33 so that the radial positions are sequentially moved outward. In addition, a band groove 34 having a + shape in plan view is formed between the respective recessed regions.

なお、摩擦低減凹部４０は扇状台座板３２の上面に貼り付けた凹部形成板３３の一枚分の厚みの凹部で形成され、バンド溝３４は凹部形成板３３と円形台座板３１の上面に貼り付けられた扇状台座板３２の２枚分の厚みの凹部で形成している。   The friction reducing recess 40 is formed by a recess having a thickness corresponding to one recess forming plate 33 attached to the upper surface of the fan-shaped pedestal plate 32, and the band groove 34 is attached to the upper surfaces of the recess forming plate 33 and the circular pedestal plate 31. The fan-shaped pedestal plate 32 is provided with two concave portions having a thickness.

さらに、帯円弧状凹部形成板３３ｂｂの外周付近に、下面緩衝プレート３０をコイル下面１１ｂに当接させる向きを明示する管端位置マーク５０を備えている。また、摩擦低減凹部４０の位置を明示する位置明示手段として機能する、「○」及び「×」で示した凹部位置マーク４１をバンド溝３４に備えるとともに、円形台座板３１、扇状台座板３２及び凹部形成板３３の色を変更している。   Further, a tube end position mark 50 is provided in the vicinity of the outer periphery of the belt-arc-shaped recess forming plate 33bb to clearly indicate the direction in which the lower buffer plate 30 is brought into contact with the coil lower surface 11b. Further, the band groove 34 is provided with a concave position mark 41 indicated by “◯” and “X”, which functions as a position indication means for clearly indicating the position of the friction reducing concave portion 40, and the circular pedestal plate 31, the fan-shaped pedestal plate 32, and The color of the recess forming plate 33 is changed.

詳しくは、管端位置マーク５０に近い方の図４の右側のバンド溝３４に○マーク４１ａを、管端位置マーク５０と遠い方の左側のバンド溝３４に×マーク４１ｂを備えている。
また、円形台座板３１を茶色、扇状台座板３２を白色、凹部形成板３３を緑色に着色している。 More specifically, a circle mark 41a is provided in the right band groove 34 in FIG. 4 closer to the tube end position mark 50, and a cross mark 41b is provided in the left band groove 34 farther from the tube end position mark 50.
Further, the circular pedestal plate 31 is colored brown, the fan-shaped pedestal plate 32 is colored white, and the recess forming plate 33 is colored green.

ＬＷＣ１０は、連続する銅管１２を軸方向Ｌに整列巻き且つトラバース巻きによって、径方向Ｒに複数層巻き回してコイル状に構成している。（図２参照）
なお、銅管１２は、空調装置の熱交換器等に用いられる内面溝付管や平滑管等の伝熱管に用いられる銅又は銅合金の管である。 The LWC 10 is formed in a coil shape by winding a plurality of layers in the radial direction R by arranging and winding a continuous copper tube 12 in the axial direction L and traverse winding. (See Figure 2)
The copper pipe 12 is a copper or copper alloy pipe used for a heat transfer pipe such as an internally grooved pipe or a smooth pipe used for a heat exchanger or the like of an air conditioner.

ＬＷＣ１０は、図６，７に示すように、ボビン１００に対して平面視反時計回りに径内側から径外側に向かって巻き付けて形成している。さらに詳しくは、まず、ボビン軸１０１に沿って一方のフランジ１０２（１０２ａ，１０２ｂ）から他方側のフランジ向かって巻き付けていく。   As shown in FIGS. 6 and 7, the LWC 10 is formed by winding the bobbin 100 counterclockwise in a plan view from the radially inner side toward the radially outer side. More specifically, first, winding is performed from one flange 102 (102a, 102b) toward the other flange along the bobbin shaft 101.

なお、本実施例においては、管始端１２ａを上フランジ１０２ａ付近に配置し、１層目は下フランジ１０２ｂに向かって巻き付ける構成とする。したがって、内周側からの奇数層は上フランジ１０２ａから下フランジ１０２ｂに向かって下方向に巻き付けていき、逆に内周側からの偶数層は下フランジ１０２ｂから上フランジ１０２ａに向かって上方向に巻き付けていく構成となる。   In the present embodiment, the pipe start end 12a is disposed in the vicinity of the upper flange 102a, and the first layer is wound around the lower flange 102b. Therefore, the odd layer from the inner peripheral side is wound downwardly from the upper flange 102a toward the lower flange 102b, while the even layer from the inner peripheral side is upwardly directed from the lower flange 102b toward the upper flange 102a. It becomes composition to wind.

また、ボビン軸１０１に沿って巻き付ける銅管１２は、ボビン１００に巻き付けた１層目と２層目の銅管１２についての展開図を示す図７（ａ）に示すように、管始端１２ａからフランジ１０２に沿って、軸方向Ｌに直角な方向でボビン軸１０１に巻き付ける整列部１３ａと、次の列に遷移する列遷移部１３ｂとで構成し、これにより、銅管１２を軸方向Ｌに沿って複数列巻き付けて整列巻き層を構成している。   Further, the copper tube 12 wound along the bobbin shaft 101 is shown in FIG. 7A showing a development view of the first layer and the second layer copper tube 12 wound around the bobbin 100 from the tube start end 12a. An alignment portion 13a wound around the bobbin shaft 101 in a direction perpendicular to the axial direction L along the flange 102, and a row transition portion 13b that transitions to the next row, thereby making the copper tube 12 in the axial direction L. The aligned winding layer is formed by winding a plurality of rows along.

なお、図７（ａ）において点線で示す１層目（奇数層）では、ボビン軸１０１に沿って下方向に巻き付けていくため、列遷移部１３ｂは図７（ａ）において右下がりとなり、図７（ａ）において実線で示す２層目（偶数層）では、ボビン軸１０１に沿って上方向に巻き付けていくため、列遷移部１３ｂは図７（ａ）において右上がりとなる。   Note that in the first layer (odd layer) indicated by the dotted line in FIG. 7A, winding is performed downward along the bobbin axis 101, so that the column transition portion 13b is lowered to the right in FIG. In the second layer (even layer) indicated by a solid line in FIG. 7 (a), the column transition portion 13b rises to the right in FIG. 7 (a) because it is wound upward along the bobbin axis 101.

また、列遷移部１３ｂは、銅管１２の管径や表面の滑り具合で長さ、すなわち整列部１３ａに対する角度が異なるが、図７に示す本実施例ではおよそ整列部１３ａの半分程度の長さで構成している。   Further, the length of the row transition portion 13b differs depending on the diameter of the copper tube 12 and the slippage of the surface, that is, the angle with respect to the alignment portion 13a. In this embodiment shown in FIG. 7, the length is about half that of the alignment portion 13a. It is composed.

このような構成の整列巻き層を径外側方向に複数層分形成して構成したＬＷＣ１０において、前層から次層へは、層遷移部１４によって層間を跨いで遷移する。
詳しくは、図７（ａ）における各断面（ａ乃至ｄ）の断面図を示す図７（ｂ）において、整列部１３ａの始端位置であるｄ−ｄ断面から整列部１３ａの終端位置であるａ−ａ断面まで巻き付けた１層目の銅管１２の最下段１２ｂは、１層目の最下列遷移部１３ｂａと下フランジ１０２ｂとの隙間に入りきれず、最下列遷移部１３ｂａの径外側を巻き付け、１層目と２層目を跨いで遷移する下面側層遷移部１４ｂを構成することとなる。 In the LWC 10 configured by forming a plurality of aligned winding layers in the radially outward direction in such a configuration, the layer transition unit 14 makes a transition across the layers from the previous layer to the next layer.
Specifically, in FIG. 7B, which shows a cross-sectional view of each cross section (a to d) in FIG. 7A, the end position of the alignment portion 13a from the dd cross section that is the start end position of the alignment portion 13a. The lowermost step 12b of the first-layer copper tube 12 wound up to the -a cross section cannot fit into the gap between the lowermost row transition portion 13ba of the first layer and the lower flange 102b, and wraps around the outer diameter of the lowermost row transition portion 13ba. The lower surface side layer transition portion 14b that transitions across the first layer and the second layer is configured.

そして、１層目から２層目へ整列巻き層を跨いで遷移した下面側層遷移部１４ｂは、整列部１３ａの始端位置であるｄ−ｄ断面に示すように、１層目の管と管との間に位置して２層目の整列部１３ａを構成する。このような前層の管と管との間に次層の管を配置する巻き方をトラバース巻きという。   Then, the lower surface side layer transition portion 14b that has transitioned from the first layer to the second layer across the aligned winding layer has a tube and a tube of the first layer as shown in the dd cross section which is the starting end position of the alignment portion 13a. And the second layer of the alignment portion 13a. Such a winding method in which the tube of the next layer is arranged between the tubes of the previous layer is called traverse winding.

このように、最上下段の列遷移部１３ｂにかぶさるようにして形成される層遷移部１４による層遷移を繰り返して、径方向に整列巻きした銅管１２による複数層構成のＬＷＣ１０を構成している。そして、上記１層目（奇数層）から２層目（偶数層）へ遷移する下面側層遷移部１４ｂは、図６に示すＬＷＣ１０の底面図に示すように、ＬＷＣ１０の下側で遷移してコイル下面１１ｂに出現する。   As described above, the layer transition by the layer transition portion 14 formed so as to cover the uppermost row transition portion 13b is repeated, and the multi-layered LWC 10 is configured by the copper tubes 12 aligned in the radial direction. . And the lower surface side layer transition part 14b which changes from the first layer (odd layer) to the second layer (even layer) transitions below the LWC 10 as shown in the bottom view of the LWC 10 shown in FIG. Appears on the coil lower surface 11b.

これに対し、偶数層から奇数層へ遷移する上面側層遷移部１４ａは、ＬＷＣ１０の上側で遷移してコイル上面１１ａに出現する。なお、最上下段の列遷移部１３ｂにかぶさるようにして形成される層遷移部１４は、図６に示すように、銅管１２の巻き付け方向にズレて出現する。   On the other hand, the upper surface side layer transition portion 14a that transitions from the even layer to the odd layer transitions on the upper side of the LWC 10 and appears on the coil upper surface 11a. It should be noted that the layer transition portion 14 formed so as to cover the lowermost row transition portion 13b appears shifted in the winding direction of the copper tube 12, as shown in FIG.

このようにして、内周側の管始端１２ａから外周側の管終端１２ｃまでをボビン１００のボビン軸１０１に巻き付けて構成したＬＷＣ１０は、この状態で銅管１２の製造工程のうち焼鈍工程を経て、ボビン１００を解体し、図６において点線で示す結束バンド６０でＬＷＣ１０の４方向を結束して、コイル形態を保持している。   In this manner, the LWC 10 configured by winding the inner pipe end 12a to the outer pipe end 12c around the bobbin shaft 101 of the bobbin 100 in this state undergoes an annealing process among the copper pipe 12 manufacturing processes. The bobbin 100 is disassembled, and the four directions of the LWC 10 are bound by a binding band 60 indicated by a dotted line in FIG.

そして、結束バンド６０で４方向を結束したＬＷＣ１０を、図３に示すように、管終端１２ｃと管端位置マーク５０とを合わせて下面緩衝プレート３０の上面にＬＷＣ１０を載置する。そして、バンド溝３４を通過させて結束バンド６０を外し、帯状ビニールカバー２１でＬＷＣ１０の外周面を巻き回してカバーする。これを上下方向に繰り返して載置して梱包済ＬＷＣ１を構成する。   Then, as shown in FIG. 3, the LWC 10, which is bound in four directions by the binding band 60, is placed on the upper surface of the lower buffer plate 30 with the tube terminal end 12 c and the tube end position mark 50 aligned. Then, the band band 34 is passed and the binding band 60 is removed, and the outer circumferential surface of the LWC 10 is wound and covered with the belt-like vinyl cover 21. This is repeated in the up and down direction to form the packed LWC1.

これにより、図４に示すように、１層目から２層目の第１下面側層遷移部１４ｂａが第１凹部領域の扇状凹部４０ａに対向する態様でコイル下面１１ｂと下面緩衝プレート３０とを当接させた状態で梱包することができる。   As a result, as shown in FIG. 4, the coil lower surface 11 b and the lower surface buffer plate 30 are arranged so that the first lower surface side layer transition portion 14 ba of the first layer to the second layer faces the fan-shaped concave portion 40 a of the first concave region. It can be packed in a contacted state.

同様に、３層目から４層目の第２下面側層遷移部１４ｂｂが、第１凹部領域の扇状凹部４０ａとバンド溝３４と第２凹部領域における小径帯円弧状凹部４０ｂとを跨いで対向する態様となり、５層目から６層目の第３下面側層遷移部１４ｂｃが、第２凹部領域における小径帯円弧状凹部４０ｂに対向する態様となる。   Similarly, the second lower surface side layer transition portion 14bb of the third to fourth layers is opposed across the fan-shaped recess 40a, the band groove 34 in the first recess region, and the small-diameter arc-shaped recess 40b in the second recess region. The third lower surface side layer transition portion 14bc of the fifth to sixth layers faces the small-diameter arc-shaped concave portion 40b in the second concave region.

７層目から８層目の第４下面側層遷移部１４ｂｄは、第２凹部領域における小径帯円弧状凹部４０ｂとバンド溝３４と第３凹部領域における中径帯円弧状凹部４０ｃとを跨いで対向する態様となり、９層目から１０層目の第５下面側層遷移部１４ｂｅが、第３凹部領域における中径帯円弧状凹部４０ｃに対向する態様となる。   The fourth lower surface side layer transition portion 14bd of the seventh to eighth layers straddles the small-diameter band arc-shaped recess 40b in the second recess area, the band groove 34, and the medium-diameter arc-shaped recess 40c in the third recess area. The fifth lower surface side layer transition portion 14be in the ninth to tenth layers is opposed to the medium-diameter arc-shaped concave portion 40c in the third concave region.

１１層目から１２層目の第６下面側層遷移部１４ｂｆは、第３凹部領域における中径帯円弧状凹部４０ｃとバンド溝３４と第４凹部領域における大径帯円弧状凹部４０ｄとを跨いで対向する態様となり、１３層目から１４層目の第７下面側層遷移部１４ｂｇが、第４凹部領域における大径帯円弧状凹部４０ｄに対向する態様となる。   The sixth lower surface side layer transition portion 14bf of the 11th layer to the 12th layer straddles the medium-diameter arcuate recess 40c and the band groove 34 in the third recess region and the large-diameter arcuate recess 40d in the fourth recess region. The seventh lower surface side layer transition portion 14bg of the 13th layer to the 14th layer faces the large-diameter arcuate recess 40d in the fourth recess region.

このような構成の梱包済ＬＷＣ１から所望の長さの銅管１２を引き出すＥＴＴＳ方式について詳述する。まず、図１に示すように、上下方向にＬＷＣ１０を積み重ねて構成した梱包済ＬＷＣ１のうち、最上段のＬＷＣ１０の内周側から管始端１２ａを上方に引き出す。   A detailed description will be given of the ETTS method for drawing a copper tube 12 having a desired length from the packed LWC 1 having such a configuration. First, as shown in FIG. 1, the pipe start end 12 a is drawn upward from the inner peripheral side of the uppermost LWC 10 in the packed LWC 1 configured by stacking the LWCs 10 in the vertical direction.

なお、このとき、銅管１２は、ＬＷＣ１０の平面視中心から上方に引き出されるよう、載置した梱包済ＬＷＣ１の平面視中央上方に配置したベント管（図示省略）を通して引き出される。そして、内周側の１層目の管始端１２ａから順に引き出される。   At this time, the copper pipe 12 is drawn out through a vent pipe (not shown) disposed at the upper center of the packaged LWC 1 placed so as to be drawn upward from the center of the LWC 10 in plan view. And it pulls out in order from the pipe | tube start end 12a of the 1st layer of an inner peripheral side.

このように、内周側１層目の管始端１２ａから順に引き出されるＥＴＴＳ方式では、偶数層から奇数層への上面側層遷移部１４ａでは問題とならない。しかし、図８に示すように、ＬＷＣ１０のコイル下面１１ｂに出現する奇数層から偶数層への下面側層遷移部１４ｂにおいては、まだ引き出されていない偶数層の銅管１２（これを直上銅管１２ｄという）が下面側層遷移部１４ｂの上方に残っているため、直上銅管１２ｄと下面緩衝プレート３０の当接面３５との間で挟まれることとなる。   As described above, in the ETTS system that is drawn in order from the tube start end 12a of the first inner layer, there is no problem in the upper surface side layer transition portion 14a from the even layer to the odd layer. However, as shown in FIG. 8, in the lower layer side layer transition portion 14b from the odd layer to the even layer that appears on the coil lower surface 11b of the LWC 10, the copper tube 12 of the even layer that has not yet been drawn out (this is directly above the copper tube 12). 12d) remains above the lower surface side layer transition portion 14b, and therefore, is sandwiched between the upper copper pipe 12d and the contact surface 35 of the lower surface buffer plate 30.

摩擦低減凹部４０を備えない場合の図８ａ部拡大図に示すように、この直上銅管１２ｄと下面緩衝プレート３０の当接面３５との間で挟まれた状態で、銅管１２を引き出すために矢印ｃ方向の引き出し力が銅管１２にかかると中空銅管である銅管１２はキンクし、破損する。   As shown in the enlarged view of FIG. 8a when the friction reducing recess 40 is not provided, in order to pull out the copper tube 12 in a state of being sandwiched between the directly upper copper tube 12d and the contact surface 35 of the lower buffer plate 30. When the pulling force in the direction of the arrow c is applied to the copper tube 12, the copper tube 12 which is a hollow copper tube is kinked and broken.

しかし、図８ａ部拡大図において点線で示す摩擦低減凹部４０を下面緩衝プレート３０の当接面３５における下面側層遷移部１４ｂに対向する箇所に形成したことによって、上方に直上銅管１２ｄがある下面側層遷移部１４ｂであっても、直上銅管１２ｄと当接面３５との間に挟まることを防止できる。したがって、スムーズに下面側層遷移部１４ｂを矢印ｃ方向に引き出すことができる。   However, since the friction reducing recess 40 indicated by the dotted line in the enlarged view of FIG. 8a is formed at a position facing the lower surface side layer transition portion 14b on the abutting surface 35 of the lower buffer plate 30, there is a copper pipe 12d directly above. Even the lower surface side layer transition portion 14b can be prevented from being sandwiched between the upper copper pipe 12d and the contact surface 35. Therefore, the lower surface side layer transition part 14b can be pulled out smoothly in the direction of the arrow c.

このように、下面緩衝プレート３０の当接面３５における下面側層遷移部１４ｂの対向する箇所に摩擦低減凹部４０を形成したことによって、梱包済ＬＷＣ１からＥＴＴＳ方式によって、銅管１２を破損させることなく、スムーズに引き出して使用することができる。   Thus, the copper tube 12 is damaged from the packed LWC 1 by the ETTS method by forming the friction reducing recess 40 at the location where the lower surface side layer transition portion 14 b faces the contact surface 35 of the lower surface buffer plate 30. It can be pulled out and used smoothly.

なお、このようにＥＴＴＳ方式によって、銅管１２を破損させることなく、スムーズに引き出して使用することができる梱包済ＬＷＣ１は、上述したように、上下方向、すなわち梱包済ＬＷＣ１の軸方向Ｌに積み重ねて載置し、最上段のＬＷＣ１０の内周側から銅管１２を引き出すこととなる（図１参照）。   The packed LWC 1 that can be smoothly pulled out and used without damaging the copper tube 12 by the ETTS method is stacked in the vertical direction, that is, the axial direction L of the packed LWC 1 as described above. The copper tube 12 is pulled out from the inner peripheral side of the uppermost LWC 10 (see FIG. 1).

このとき、梱包済ＬＷＣ１は、下面緩衝プレート３０の摩擦低減凹部４０の回転位置が積重ね軸Ｈに対して軸対照となるように各ＬＷＣ１０（１０ａ〜１０ｄ）を積み重ねて構成している。
詳しくは、最下段の１段目ＬＷＣ１０ｄは、手前側に管端位置マーク５０と遠い方の×マーク４１ｂが見えるように配置した下面緩衝プレート３０ｄの上に載置する。そして、その１段目ＬＷＣ１０ｄのコイル上面１１ａに下面緩衝プレート３０ｃを配置し、その上面に２段目ＬＷＣ１０ｃを配置する。 At this time, the packed LWC 1 is configured by stacking the LWCs 10 (10a to 10d) so that the rotational position of the friction reducing recess 40 of the lower-surface buffer plate 30 is an axis reference with respect to the stacking axis H.
Specifically, the lowermost first stage LWC 10d is placed on the lower buffer plate 30d arranged so that the tube end position mark 50 and the far side x mark 41b can be seen on the front side. Then, the lower buffer plate 30c is disposed on the coil upper surface 11a of the first-stage LWC 10d, and the second-stage LWC 10c is disposed on the upper surface thereof.

これを繰り返し、２段目ＬＷＣ１０ｃと３段目ＬＷＣ１０ｂとの間に下面緩衝プレート３０ｂを配置し、３段目ＬＷＣ１０ｂと最上段ＬＷＣ１０ａとの間に下面緩衝プレート３０ａを配置している。   By repeating this, the lower surface buffer plate 30b is disposed between the second stage LWC 10c and the third stage LWC 10b, and the lower surface buffer plate 30a is disposed between the third stage LWC 10b and the uppermost LWC 10a.

そして、下面緩衝プレート３０ｂは、上述の下面緩衝プレート３０ｄと同様に、手前側に管端位置マーク５０と遠い方の×マーク４１ｂが見える向きで配置している。
これに対し、下面緩衝プレート３０ｃと下面緩衝プレート３０aとは、手前側に管端位置マーク５０と近い方の○マーク４１ａが見える向きで配置している。 The lower buffer plate 30b is arranged in a direction in which the tube end position mark 50 and the far side x mark 41b can be seen on the front side, similarly to the lower buffer plate 30d described above.
On the other hand, the lower surface buffer plate 30c and the lower surface buffer plate 30a are arranged in such a direction that the circle mark 41a closer to the tube end position mark 50 can be seen on the near side.

これにより、上下に積み重ねた下面緩衝プレート３０（３０ａ〜３０ｄ）は、扇状凹部４０ａと中径帯円弧状凹部４０ｃとが交互に同方向となり、同様に、小径帯円弧状凹部４０ｂと大径帯円弧状凹部４０ｄとが交互に同方向となる。   As a result, the lower buffer plates 30 (30a to 30d) stacked one above the other have the fan-shaped recesses 40a and the medium-diameter arcuate recesses 40c alternately in the same direction, and similarly, the small-diameter arcuate recesses 40b and the large-diameter bands The arcuate recesses 40d are alternately in the same direction.

よって、周方向の厚みが摩擦低減凹部４０によって部分的に異なる下面緩衝プレート３０を、摩擦低減凹部４０の配置が軸対象となる方向でＬＷＣ１０を積み重ねて梱包済ＬＷＣ１を構成したことによって、摩擦低減凹部４０が同方向に重なるように下面緩衝プレート３０（３０ａ〜３０ｄ）を同方向に配置し、ＬＷＣ１０を積み重ねた場合に生じる傾きを防止することができる。   Therefore, the lower-surface buffer plate 30 whose circumferential thickness is partially different depending on the friction-reducing recesses 40 is configured by stacking the LWCs 10 in the direction in which the arrangement of the friction-reducing recesses 40 is the axis target, thereby reducing the friction. The lower surface buffer plates 30 (30a to 30d) are arranged in the same direction so that the recesses 40 are overlapped in the same direction, and an inclination generated when the LWCs 10 are stacked can be prevented.

なお、上述の説明においては、銅管１２の巻き付け方向にズレて出現する下面側層遷移部１４ｂに対向する下面緩衝プレート３０の当接面３５に形成する摩擦低減凹部４０を、形状の異なる凹部形成板３３を組み合わせて構成したが、その他の方法で摩擦低減凹部４０を構成してもよい。   In the above description, the friction reducing recess 40 formed on the contact surface 35 of the lower surface buffer plate 30 facing the lower surface side layer transition portion 14b that appears shifted in the winding direction of the copper tube 12 is a recess having a different shape. Although the formation plate 33 is combined, the friction reducing recess 40 may be formed by other methods.

例えば、３層構成の下面緩衝プレート３０を１層で構成し、図９に示すように、下面側層遷移部１４ｂに対向する箇所を連続させて、平面視略渦巻き状の渦巻凹部４２を形成してもよい。渦巻凹部４２を備えた下面緩衝プレート３０であっても摩擦低減凹部４０を備えた下面緩衝プレート３０と同様に効果を得ることができる。   For example, the lower-surface buffer plate 30 having a three-layer structure is formed of a single layer, and as shown in FIG. 9, the portions facing the lower-surface side layer transition portion 14b are continuous to form a spiral recess 42 having a substantially spiral shape in plan view. May be. Even in the case of the lower buffer plate 30 having the spiral recess 42, the same effect as that of the lower buffer plate 30 having the friction reducing recess 40 can be obtained.

次に、上述した本実施形態の下面緩衝プレート３０、下面緩衝プレート３０を用いた梱包済ＬＷＣ１、並びに梱包済ＬＷＣ１の載置方法による作用効果について説明する。連続する銅管１２を整列巻き且つトラバース巻きによって、径方向Ｒに複数層巻き回してコイル状に構成したＬＷＣ１０を梱包する梱包材２０のうちコイル下面１１ｂに当接させる下面緩衝プレート３０の当接面３５における、ＬＷＣ１０の層間を跨いで奇数層から外側の偶数層に遷移する銅管１２の下面側層遷移部１４ｂに対向する箇所に、該下面側層遷移部１４ｂとの摩擦を低減する摩擦低減凹部４０を備えた。   Next, the effects of the above-described lower surface buffer plate 30, the packed LWC1 using the lower surface buffer plate 30, and the packaging method of the packed LWC1 will be described. Contact of the lower surface buffer plate 30 that contacts the coil lower surface 11b of the packing material 20 for packing the LWC 10 configured in a coil shape by winding a plurality of layers in the radial direction R by aligned winding and traverse winding. Friction that reduces friction with the lower surface side layer transition portion 14b at the position facing the lower surface side layer transition portion 14b of the copper tube 12 that transitions from the odd layer to the outer even layer across the LWC 10 layer on the surface 35 A reduction recess 40 was provided.

これにより、連続する銅管１２を整列巻き且つトラバース巻きによって、径方向Ｒに複数層巻き回してコイル状に構成したＬＥＣ１０から、銅管１２を破損させることなく、ＥＴＴＳ方式によって銅管１２を確実に引き出すことができる。   Thereby, the copper tube 12 can be reliably secured by the ETTS method without damaging the copper tube 12 from the LEC 10 configured in a coil shape by winding a plurality of layers in the radial direction R by aligned winding and traverse winding. Can be pulled out.

詳しくは、銅管１２を上方に引き出すＥＴＴＳ方式において、下面緩衝プレート３０における、下面側層遷移部１４ｂに対向する箇所に、該下面側層遷移部１４ｂとの摩擦を低減する摩擦低減凹部４０を形成したことにより、引き出されていない直上銅管１２ｄが上方に残っている下面側層遷移部１４ｂが当接面３５と直上銅管１２ｄとの間で挟まれることを防止できる。したがって、引っ張り負荷によって下面側層遷移部１４ｂがキンクして破損することなく、銅管１２を確実に引き出すことができる。   Specifically, in the ETTS system that pulls the copper tube 12 upward, a friction reducing recess 40 that reduces friction with the lower surface side layer transition portion 14b is provided at a position facing the lower surface side layer transition portion 14b in the lower surface buffer plate 30. By forming, it can prevent that the lower surface side layer transition part 14b in which the upper copper pipe 12d not drawn out remains is sandwiched between the contact surface 35 and the upper copper pipe 12d. Therefore, the copper pipe 12 can be reliably pulled out without the lower surface side layer transition portion 14b being kinked and damaged by the tensile load.

また、下面緩衝プレート３０のバンド溝３４に、摩擦低減凹部４０の位置を明示する凹部位置マーク４１を備えるとともに、摩擦低減凹部４０の位置を明示するために、扇状台座板３２及び凹部形成板３３の色を変更している。これにより、下面緩衝プレート３０における摩擦低減凹部４０の位置を容易に確認してＬＷＣ１０を梱包することができる。   In addition, the band groove 34 of the lower buffer plate 30 is provided with a recess position mark 41 that clearly indicates the position of the friction reducing recess 40, and in order to clearly indicate the position of the friction reducing recess 40, the fan-shaped base plate 32 and the recess forming plate 33. The color has changed. Thereby, the position of the friction reduction recessed part 40 in the lower surface buffer plate 30 can be confirmed easily, and the LWC 10 can be packed.

また、下面緩衝プレート３０の当接面３５に管端位置マーク５０を備えたため、摩擦低減凹部４０を下面側層遷移部１４ｂに対向する位置で下面緩衝プレート３０をＬＷＣ１０に当接させて梱包することができる。したがって、ＥＴＴＳ方式によって破損することなく銅管１２を確実に引き出すことができる。   Further, since the pipe end position mark 50 is provided on the abutting surface 35 of the lower surface buffer plate 30, the lower surface buffer plate 30 is brought into contact with the LWC 10 at a position facing the lower surface side layer transition portion 14b. be able to. Therefore, the copper tube 12 can be reliably pulled out without being damaged by the ETTS method.

また、梱包済ＬＷＣ１は、摩擦低減凹部４０を備えた下面緩衝プレート３０をコイル下面１１ｂに当接させて構成しているため、ＬＷＣ１０のコイル下面１１ｂに下面緩衝プレート３０を介在させたまま、銅管１２を上方に引き出すＥＴＴＳ方式において、破損することなく銅管１２を確実に引き出すことができる。   Further, since the packaged LWC 1 is configured such that the lower surface buffer plate 30 having the friction reducing recess 40 is brought into contact with the coil lower surface 11b, the lower surface buffer plate 30 remains interposed on the coil lower surface 11b of the LWC 10. In the ETTS method in which the pipe 12 is pulled upward, the copper pipe 12 can be reliably pulled out without being damaged.

さらにまた、梱包済ＬＷＣ１を下面緩衝プレート３０の摩擦低減凹部４０の配置が積重ね軸Ｈに対して軸対照となるよう積み重ねて構成したため、摩擦低減凹部４０が同方向に配置された状態で積み重ねた場合に生じる梱包済ＬＷＣ１の傾きを防止することができる。   Furthermore, since the packaged LWC 1 is configured such that the arrangement of the friction reducing recesses 40 of the lower buffer plate 30 is aligned with the stacking axis H, the packed LWCs 1 are stacked with the friction reducing recesses 40 arranged in the same direction. Inclination of the packed LWC 1 that occurs in some cases can be prevented.

なお、上述の説明においては下面緩衝プレート３０を、無架橋低発泡ポリプロピレンシート製で構成したが、紙段ボール製、プラスチック段ボール製、樹脂板製、発泡樹脂板製、あるいは木板製の緩衝プレートであってもよい。   In the above description, the lower buffer plate 30 is made of a non-crosslinked low-foamed polypropylene sheet. However, the lower buffer plate 30 is a buffer plate made of paper cardboard, plastic cardboard, resin board, foamed resin board, or wood board. May be.

また、上記摩擦低減手段として下面緩衝プレート３０の当接面３５における下面側層遷移部１４ｂに対向する部分に形成した凹状の摩擦低減凹部４０で構成したが、下面側層遷移部１４ｂに対向する部分に埋め込んだスポンジ等の変形性の高い高変形性部材で構成してもよい。   Moreover, although it comprised with the concave friction reduction recessed part 40 formed in the part facing the lower surface side layer transition part 14b in the contact surface 35 of the lower surface buffer plate 30 as said friction reduction means, it opposes the lower surface side layer transition part 14b. You may comprise highly deformable members with high deformability, such as sponge embedded in the part.

これにより、上方の直上銅管１２ｄと、下面緩衝プレート３０の当接面３５とに挟まれた下面側層遷移部１４ｂを引き出す際に、変形性の高い摩擦低減手段が変形することで、当接面３５と下面側層遷移部１４ｂとの摩擦が低減され、破損することなく銅管１２を確実に引き出すことができる。   As a result, when the lower surface side layer transition portion 14b sandwiched between the upper copper pipe 12d above and the contact surface 35 of the lower buffer plate 30 is pulled out, the friction reducing means having high deformability is deformed. The friction between the contact surface 35 and the lower surface side layer transition portion 14b is reduced, and the copper tube 12 can be reliably pulled out without being damaged.

さらにまた、上記摩擦低減手段として機能する摩擦低減凹部４０の代替として、下面緩衝プレート３０の当接面３５における下面側層遷移部１４ｂに対向する箇所にテフロン（登録商標）等の低摩擦剤による表面処理を施してもよい。   Furthermore, as an alternative to the friction reducing recess 40 that functions as the friction reducing means, a low friction agent such as Teflon (registered trademark) is used at a location facing the lower surface side layer transition portion 14b on the contact surface 35 of the lower surface buffer plate 30. A surface treatment may be applied.

これにより、上方の直上銅管１２ｄと、下面緩衝プレート３０の当接面３５とに挟まれた下面側層遷移部１４ｂを引き出す際に、低摩擦剤による表面処理によって、当接面３５と下面側層遷移部１４ｂとの摩擦が低減され、破損することなく銅管１２を確実に引き出すことができる。   Thereby, when pulling out the lower surface side layer transition portion 14b sandwiched between the upper copper pipe 12d directly above and the contact surface 35 of the lower buffer plate 30, the contact surface 35 and the lower surface are obtained by surface treatment with a low friction agent. The friction with the side layer transition portion 14b is reduced, and the copper tube 12 can be reliably pulled out without being damaged.

なお、このように、摩擦低減手段として、下面側層遷移部１４ｂに対向する部分にのみ変形性の高い摩擦低減手段や、低摩擦剤による表面処理を行うことで、下面緩衝プレート３０に載置した状態で、ＥＴＴＳ方式によって銅管１２をスムーズに引き出すことができる。   As described above, the friction reducing means is mounted on the lower surface buffer plate 30 by performing surface treatment with a highly deformable friction reducing means or a low friction agent only on a portion facing the lower surface side layer transition portion 14b. In this state, the copper tube 12 can be pulled out smoothly by the ETTS method.

詳しくは、例えば、当接面３５の全面を変形性の高い摩擦低減手段で構成した場合、下面緩衝プレート３０全体が変形してしまい、下面側層遷移部１４ｂとの接触面積が増大することで摩擦が向上し、ＥＴＴＳ方式によって銅管１２をスムーズに引き出すことができない。   Specifically, for example, when the entire contact surface 35 is configured with highly deformable friction reducing means, the entire lower surface buffer plate 30 is deformed, and the contact area with the lower surface side layer transition portion 14b is increased. The friction is improved and the copper tube 12 cannot be pulled out smoothly by the ETTS method.

逆に、当接面３５の全面に低摩擦剤による表面処理を行うと、直上銅管１２ｄと当接面３５とで挟まれた下面側層遷移部１４ｂの引き出しはスムーズにできる。しかし、下面緩衝プレート３０に載置されたＬＷＣ１０が、当接面３５に施された表面処理によって安定せず、銅管１２の引き出しによってＬＷＣ１０が下面緩衝プレート３０上を滑り、ＥＴＴＳ方式による銅管１２の引き出しが逆に困難となるおそれがある。   On the other hand, when the entire surface of the contact surface 35 is subjected to a surface treatment with a low friction agent, the lower surface side layer transition portion 14b sandwiched between the upper copper pipe 12d and the contact surface 35 can be drawn smoothly. However, the LWC 10 placed on the lower surface buffer plate 30 is not stabilized by the surface treatment applied to the contact surface 35, and the LWC 10 slides on the lower surface buffer plate 30 by pulling out the copper tube 12, and the ETTS type copper tube On the other hand, it may be difficult to pull out twelve.

しかし、下面側層遷移部１４ｂに対向する部分にのみ変形性の高い摩擦低減手段や、低摩擦剤による表面処理を行うことで、下面緩衝プレート３０に載置した状態で、ＥＴＴＳ方式によって銅管１２をスムーズに引き出すことができる。   However, a copper tube is formed by the ETTS method in a state of being placed on the lower buffer plate 30 by performing a surface treatment with a highly deformable friction reducing means or a low friction agent only on a portion facing the lower surface side layer transition portion 14b. 12 can be pulled out smoothly.

なお、下面緩衝プレート３０の当接面３５には、凹部形成板３３と扇状台座板３２とによって二枚分の厚みの凹部状のバンド溝３４を備えているが、バンド溝３４を形成せずに、二枚分の厚みの凹部形成板３３で摩擦低減凹部を形成してもよい。   The abutting surface 35 of the lower buffer plate 30 is provided with a recess-shaped band groove 34 having a thickness of two by the recess forming plate 33 and the fan-shaped pedestal plate 32, but the band groove 34 is not formed. Alternatively, the friction reducing recesses may be formed by the recess forming plate 33 having a thickness of two sheets.

また、下面緩衝プレート３０の底面にもバンド溝３４を備えてもよい。この場合、下面緩衝プレート３０を間に挟んだ状態でＬＷＣ１０を上下方向に積み重ねた後から、バンド溝３４を通過させて結束バンド６０を外すことができる。   Further, a band groove 34 may be provided on the bottom surface of the lower buffer plate 30. In this case, after the LWCs 10 are stacked in the vertical direction with the lower surface buffer plate 30 sandwiched therebetween, the binding band 60 can be removed by passing the band groove 34.

以下、図面に基づいて第２の実施形態について詳述する。
なお、上述の実施例１の構成と同じ構成については詳細な説明を省略する。
図１０は本発明を採用した梱包済レベルワウンドコイル（以下において梱包済ＬＷＣという）１ａを積み上げてＥＴＴＳ方式で管を引き出す状態の斜視図を示し、図１１は梱包済ＬＷＣ１ａの斜視図を示し、図１２は梱包済ＬＷＣ１ａの分解斜視図を示している。 Hereinafter, the second embodiment will be described in detail based on the drawings.
Detailed description of the same configuration as that of the first embodiment is omitted.
FIG. 10 shows a perspective view of a state in which packed level wound coils (hereinafter referred to as packed LWC) 1a adopting the present invention are stacked and a pipe is pulled out by the ETTS method, and FIG. 11 shows a perspective view of packed LWC 1a, FIG. 12 shows an exploded perspective view of the packed LWC 1a.

本発明の梱包済ＬＷＣ１ａは、連続する銅管１２を軸方向Ｌに整列巻きするとともに、径方向Ｒに複数層巻き回してコイル状に構成したＬＷＣ１０を梱包材２０ａで梱包して構成している（図１１参照）。   The packaged LWC 1a of the present invention is configured by winding a continuous copper tube 12 in an axial direction L and winding a plurality of layers in the radial direction R into a coil shape and packing it with a packing material 20a. (See FIG. 11).

このように構成した梱包済ＬＷＣ１ａを上下方向に複数積み重ねて載置し、最上段の梱包済ＬＷＣ１ａのビニールカバー２１ａとコイル上面１１ａ側の上面緩衝プレート２２を取り外し、内周側から銅管１２を引き出して使用することができる。   A plurality of packed LWCs 1a configured in this way are stacked and placed in the vertical direction, the vinyl cover 21a of the uppermost packed LWC 1a and the upper surface buffer plate 22 on the coil upper surface 11a side are removed, and the copper tube 12 is attached from the inner peripheral side. Can be pulled out and used.

梱包材２０ａは、筒状の透明ビニール製であるビニールカバー２１ａと、ＬＷＣ１０のコイル上面１１ａに当接させる上面緩衝プレート２２と、コイル下面１１ｂに当接させる下面緩衝プレート３０とで構成している。   The packing material 20a includes a vinyl cover 21a made of cylindrical transparent vinyl, an upper buffer plate 22 that contacts the coil upper surface 11a of the LWC 10, and a lower buffer plate 30 that contacts the coil lower surface 11b. .

ビニールカバー２１ａは、図１２に示すように、ＬＷＣ１０の外径より一回り大きな開口を上下両端に備えた筒状であり、熱によって収縮するビニールカバーである。   As shown in FIG. 12, the vinyl cover 21a has a cylindrical shape with openings that are slightly larger than the outer diameter of the LWC 10 at both upper and lower ends, and is a vinyl cover that shrinks by heat.

下面緩衝プレート３０の素材や構成については、実施例１の下面緩衝プレート３０と同じであるため、詳細な説明は省略する。
上面緩衝プレート２２は、上述の下面緩衝プレート３０と同じ素材で構成している。 Since the material and configuration of the lower buffer plate 30 are the same as those of the lower buffer plate 30 of the first embodiment, detailed description thereof is omitted.
The upper buffer plate 22 is made of the same material as the lower buffer plate 30 described above.

コイル上面１１ａに当接する上面緩衝プレート２２は、最上層を構成する円形台座板と、円形台座板の下面側に２枚重ねて貼り付けた扇状台座板とで３層構造で構成するとともに、下面緩衝プレート３０のバンド溝３４と同様に下面視＋状のバンド溝を形成している。   The upper surface buffer plate 22 that contacts the coil upper surface 11a is configured by a three-layer structure including a circular pedestal plate that constitutes the uppermost layer and a fan-shaped pedestal plate that is affixed to the lower surface side of the circular pedestal plate. Similar to the band groove 34 of the buffer plate 30, a band groove having a + shape in a bottom view is formed.

また、上面緩衝プレート２２の上面側、すなわちコイル上面１１ａに当接しない側の反当接面２２ａにおける下面緩衝プレート３０の凹部位置マーク４１に対応する位置に凹部位置マーク４１（４１ａ，４１ｂ）を備えている。   Further, the concave position mark 41 (41a, 41b) is provided at a position corresponding to the concave position mark 41 of the lower surface buffer plate 30 on the upper surface side of the upper surface buffer plate 22, that is, the non-contact surface 22a on the side not contacting the coil upper surface 11a.

上述したような構成の梱包材２０ａを用いた梱包済ＬＷＣ１ａの梱包は、結束バンド６０で４方向を結束したＬＷＣ１０を、図１２に示すように、管終端１２ｃと管端位置マーク５０とを合わせて下面緩衝プレート３０の上面にＬＷＣ１０を載置し、そのＬＷＣ１０のコイル上面１１ａに上面緩衝プレート２２を載置する。   Packing of the finished LWC 1a using the packing material 20a having the above-described configuration is performed by aligning the LWC 10 bundled in the four directions with the binding band 60 with the pipe end 12c and the pipe end position mark 50 as shown in FIG. The LWC 10 is placed on the upper surface of the lower buffer plate 30, and the upper buffer plate 22 is placed on the coil upper surface 11 a of the LWC 10.

このようにして、上から上面緩衝プレート２２、ＬＷＣ１０及び下面緩衝プレート３０の順で重ね合わせた状態で、バンド溝３４を通過させて結束バンド６０を外し、ビニールカバー２１ａで覆い、熱風をかけて、固定して梱包済ＬＷＣ１ａを構成する。
これにより、下面側層遷移部１４ｂが摩擦低減凹部４０に対向する態様でコイル下面１１ｂと下面緩衝プレート３０とを当接させた状態で梱包することができる（図４参照）。 In this way, in the state where the upper surface buffer plate 22, LWC 10 and lower surface buffer plate 30 are overlapped in this order from the top, the band groove 34 is passed through, the binding band 60 is removed, covered with the vinyl cover 21a, and hot air is applied. The fixed LWC 1a is configured.
Thereby, it can pack in the state which contacted the coil lower surface 11b and the lower surface buffer plate 30 in the aspect in which the lower surface side layer transition part 14b opposes the friction reduction recessed part 40 (refer FIG. 4).

このような構成の梱包済ＬＷＣ１ａから所望の長さの銅管１２を引き出すＥＴＴＳ方式について詳述する。まず、図１０に示すように、上下方向に積み重ねた梱包済ＬＷＣ１ａのうち、最上段の梱包済ＬＷＣ１ａの上面緩衝プレート２２とを取り外し、内周側から管始端１２ａを上方に引き出す。   A detailed description will be given of the ETTS method for drawing out a copper tube 12 having a desired length from the packed LWC 1a having such a configuration. First, as shown in FIG. 10, among the packed LWCs 1a stacked in the vertical direction, the upper surface buffer plate 22 of the uppermost packed LWC 1a is removed, and the pipe start end 12a is pulled upward from the inner peripheral side.

このとき、下面緩衝プレート３０の当接面３５における下面側層遷移部１４ｂの対向する箇所に摩擦低減凹部４０を形成したことによって、上面緩衝プレート２２を取り外した梱包済ＬＷＣ１ａからＥＴＴＳ方式によって、銅管１２を破損させることなく、スムーズに引き出して使用することができる。   At this time, the friction reducing recess 40 is formed in the abutting surface 35 of the lower surface buffer plate 30 at the position facing the lower surface side layer transition portion 14b, so that the copper LWC 1a from which the upper surface buffer plate 22 has been removed is ETTS-processed by the ETTS method. The tube 12 can be pulled out and used without being damaged.

なお、このようにＥＴＴＳ方式によって、銅管１２を破損させることなく、スムーズに引き出して使用することができる梱包済ＬＷＣ１ａは、上述したように、上下方向、すなわち梱包済ＬＷＣ１ａの軸方向Ｌに積み重ねて載置し、最上段の梱包済ＬＷＣ１ａの上面緩衝プレート２２を取り外して、銅管１２を引き出すこととなる（図１０参照）。   Note that the packed LWC 1a that can be smoothly pulled out and used without damaging the copper tube 12 by the ETTS method is stacked in the vertical direction, that is, the axial direction L of the packed LWC 1a as described above. The upper surface buffer plate 22 of the uppermost packaged LWC 1a is removed, and the copper tube 12 is pulled out (see FIG. 10).

このとき、各梱包済ＬＷＣ１ａ（１ａ〜１ｄ）における下面緩衝プレート３０の摩擦低減凹部４０の回転位置が積重ね軸Ｈに対して軸対照となるように各梱包済ＬＷＣ１ａを積み重ねている。
詳しくは、最下段の１段目梱包済ＬＷＣ１ａｄの手前側に、管端位置マーク５０と遠い方の×マーク４１ｂが見えるように配置し、その上に、管端位置マーク５０と近い方の○マーク４１ａが見えるように２段目梱包済ＬＷＣ１ａｃを配置する。 At this time, each packed LWC 1a is stacked so that the rotational position of the friction reducing recess 40 of the lower-surface buffer plate 30 in each packed LWC 1a (1a to 1d) is an axis reference with respect to the stacked shaft H.
Specifically, the tube end position mark 50 and the far side x mark 41b are arranged to be visible on the front side of the LWC1ad in the first stage of the lowermost stage, and on the top side, the circle near the pipe end position mark 50 is placed. The second-stage packed LWC1ac is arranged so that the mark 41a can be seen.

さらに、２段目梱包済ＬＷＣ１ａｃの上に、管端位置マーク５０と遠い方の×マーク４１ｂが手前側に見えるように配置した３段目梱包済ＬＷＣ１ａｂを載置するとともに、その上に、管端位置マーク５０と近い方の○マーク４１ａが手前側に見えるように配置した最上段梱包済ＬＷＣ１ａａを載置している。   Further, on the second-stage packed LWC1ac, the third-stage packed LWC1ab arranged so that the tube end position mark 50 and the far side x mark 41b can be seen on the near side is placed, and on the pipe, The uppermost packaged LWC 1aa is placed so that the circle mark 41a closer to the end position mark 50 can be seen on the near side.

これにより、上下に積み重ねた梱包済ＬＷＣ１ａの下面緩衝プレート３０は、扇状凹部４０ａと中径帯円弧状凹部４０ｃとが交互に同方向となり、同様に、小径帯円弧状凹部４０ｂと大径帯円弧状凹部４０ｄとが交互に同方向となる。   As a result, the bottom buffer plate 30 of the packaged LWC 1a stacked up and down has the fan-shaped recesses 40a and the medium-diameter arcuate recesses 40c alternately in the same direction, and similarly, the small-diameter arcuate recesses 40b and the large-diameter band circles. The arc-shaped concave portions 40d are alternately in the same direction.

よって、周方向の厚みが摩擦低減凹部４０によって部分的に異なる下面緩衝プレート３０を、摩擦低減凹部４０の配置が軸対象となる方向で梱包済ＬＷＣ１ａを積み重ねたことによって、同形状の摩擦低減凹部４０が同方向に配置されるように梱包済ＬＷＣ１ａを積み重ねた場合に生じる傾きを防止することができる。   Therefore, the lower-surface buffer plate 30 whose circumferential thickness is partially different depending on the friction reducing recess 40 is stacked on the packed LWC 1a in a direction in which the arrangement of the friction reducing recess 40 is an axis target. The inclination which arises when the packed LWC1a is stacked so that 40 is arrange | positioned in the same direction can be prevented.

また、下面緩衝プレート３０のバンド溝３４に、摩擦低減凹部４０の位置を明示する凹部位置マーク４１を備えるとともに、摩擦低減凹部４０の位置を明示するために、扇状台座板３２及び凹部形成板３３の色を変更している。これにより、下面緩衝プレート３０における摩擦低減凹部４０の位置を容易に確認してＬＷＣ１０を梱包することができる。   In addition, the band groove 34 of the lower buffer plate 30 is provided with a recess position mark 41 that clearly indicates the position of the friction reducing recess 40, and in order to clearly indicate the position of the friction reducing recess 40, the fan-shaped base plate 32 and the recess forming plate 33. The color has changed. Thereby, the position of the friction reduction recessed part 40 in the lower surface buffer plate 30 can be confirmed easily, and the LWC 10 can be packed.

また、上面緩衝プレート２２上面に凹部位置マーク４１を備えたため、梱包済ＬＷＣ１ａ外部から摩擦低減凹部４０の位置を容易に確認することができる。したがって、下面緩衝プレート３０に備えた摩擦低減凹部４０の位置を確認しながら梱包済ＬＷＣ１ａを搬送等において取り扱うことができ、利便性が向上する。   Moreover, since the recessed portion position mark 41 is provided on the upper surface of the upper buffer plate 22, the position of the friction reducing recessed portion 40 can be easily confirmed from the outside of the packed LWC 1a. Therefore, the packed LWC 1a can be handled in transportation or the like while confirming the position of the friction reducing recess 40 provided in the lower buffer plate 30, and convenience is improved.

また、下面緩衝プレート３０の当接面３５に管端位置マーク５０を備えたため、摩擦低減凹部４０を下面側層遷移部１４ｂに対向する位置で下面緩衝プレート３０をＬＷＣ１０に当接させて梱包することができる。したがって、ＥＴＴＳ方式によって破損することなく銅管１２を確実に引き出すことができる。   Further, since the pipe end position mark 50 is provided on the abutting surface 35 of the lower surface buffer plate 30, the lower surface buffer plate 30 is brought into contact with the LWC 10 at a position facing the lower surface side layer transition portion 14b. be able to. Therefore, the copper tube 12 can be reliably pulled out without being damaged by the ETTS method.

また、梱包済ＬＷＣ１ａは、摩擦低減凹部４０を備えた下面緩衝プレート３０をコイル下面１１ｂに当接させて梱包しているため、上面緩衝プレート２２を取り外すだけで、ＬＷＣ１０のコイル下面１１ｂに下面緩衝プレート３０を介在させたまま、銅管１２を上方に引き出すＥＴＴＳ方式において、破損することなく銅管１２を確実に引き出すことができる。   Further, since the packed LWC 1a is packed with the lower surface buffer plate 30 provided with the friction reducing recess 40 in contact with the coil lower surface 11b, the lower surface buffer plate 22 can be disposed on the coil lower surface 11b of the LWC 10 simply by removing the upper surface buffer plate 22. In the ETTS method in which the copper tube 12 is pulled upward with the plate 30 interposed, the copper tube 12 can be reliably pulled out without being damaged.

さらにまた、梱包済ＬＷＣ１ａを、下面緩衝プレート３０の摩擦低減凹部４０の配置が積重ね軸Ｈに対して軸対照となるよう積み重ねたため、摩擦低減凹部４０が同方向に配置された状態で積み重ねた場合に生じる梱包済ＬＷＣ１ａの傾きを防止することができる。   Furthermore, when the packed LWC 1a is stacked in such a manner that the friction reducing recesses 40 of the lower surface buffer plate 30 are aligned with the stacking axis H so that the friction reducing recesses 40 are arranged in the same direction. Inclination of the packed LWC 1a occurring in the case can be prevented.

なお、コイル上面１１ａに当接する上面緩衝プレート２２及び下面緩衝プレート３０の両方にバンド溝３４を形成しているため、梱包済ＬＷＣ１ａを上下方向に積み重ねて載置してからでもバンド溝３４を通過させて結束バンド６０を取り外すことができる。また、バンド溝３４を備えていない上面緩衝プレート２２あるいは下面緩衝プレート３０を用いてもよい。   Since the band groove 34 is formed in both the upper buffer plate 22 and the lower buffer plate 30 that are in contact with the coil upper surface 11a, it passes through the band groove 34 even after the packed LWC 1a is stacked in the vertical direction. Thus, the binding band 60 can be removed. Further, the upper buffer plate 22 or the lower buffer plate 30 that does not include the band groove 34 may be used.

また、上述の実施例においては、ＬＷＣ１０のコイル下面１１ｂにのみ摩擦低減凹部４０を形成した下面緩衝プレート３０を当接させて梱包したが、ＬＷＣ１０のコイル上面１１ａにも、上面側層遷移部１４ａに対応する箇所に摩擦低減凹部４０を形成した上面緩衝プレートを当接させて梱包してもよい。   Further, in the above-described embodiment, the lower surface buffer plate 30 in which the friction reducing recess 40 is formed is brought into contact only with the coil lower surface 11b of the LWC 10, and the upper surface side layer transition portion 14a is also formed on the coil upper surface 11a of the LWC 10. The upper surface buffer plate having the friction reducing recess 40 formed thereon may be brought into contact with the portion corresponding to the above and packed.

これにより、梱包済ＬＷＣ１ａを上下逆さまで載置し、ＥＴＴＳ方式で銅管１２を引き出す際であっても、上面側層遷移部１４ａに対向する部分に形成された摩擦低減凹部４０によって、上下逆さまに配置された上面側層遷移部１４ａが上面緩衝プレートの当接面と直上銅管１２ｄとの間で挟まれることを防止できる。したがって、引っ張り負荷によって上面側層遷移部１４ａがキンクして破損することなく、銅管１２を確実に引き出すことができる。
また、下面緩衝プレート３０の当接面３５と、上面緩衝プレート２２の反当接面２２ａに、○マーク４１ａ及び×マーク４１ｂの両方を備えたが一方のみ備えてももちろんよい。 Thus, even when the packed LWC 1a is placed upside down and the copper tube 12 is pulled out by the ETTS method, the friction reducing recess 40 formed in the portion facing the upper surface side layer transition portion 14a is turned upside down. It is possible to prevent the upper surface side layer transition portion 14a disposed on the upper surface buffer plate from being sandwiched between the contact surface of the upper surface buffer plate and the upper copper pipe 12d. Therefore, the copper tube 12 can be reliably pulled out without the upper surface side layer transition portion 14a being kinked and damaged by the tensile load.
Further, although both the circle mark 41a and the x mark 41b are provided on the contact surface 35 of the lower buffer plate 30 and the anti-contact surface 22a of the upper buffer plate 22, it is needless to say that only one of them may be provided.
