Description

本発明は、エアコンなどの空調冷凍機の伝熱管（内面溝付管および平滑管など）、建築物の給湯・給水配管などに使用されるもので、銅又は銅合金管などをコイル状に多層に整列巻きし、その軸方向が垂直になるように配置され、巻き解かれるレベルワウンドコイルおよび、そのレベルワウンドコイルで構成されるレベルワウンドコイル梱包体に関する。   The present invention is used for heat transfer pipes (such as internally grooved pipes and smooth pipes) of air conditioning refrigerators such as air conditioners, hot water supply / water supply pipes for buildings, etc., and copper or copper alloy pipes are multilayered in a coil shape. And a level-wound coil package comprising the level-wound coil and the level-wound coil that is arranged and unwound so that its axial direction is vertical.

レベルワウンドコイル（Ｌｅｖｅｌ Ｗｏｕｎｄ Ｃｏｉｌ：以下、ＬＷＣと称す）は、通常、図１０に示すように、複数個のＬＷＣが、その軸方向が垂直になるように配置された多段積みＬＷＣ梱包体として提供される。図１０において、１０は多段積みＬＷＣ梱包体、１１はＬＷＣ、８は多段積みしたＬＷＣを仕切る板材（緩衝材となるドーナツ紙など）、１２はＬＷＣを巻き解く場合の管２を案内するガイド、１３はＬＷＣを積載するパレットである。   A level-wound coil (hereinafter referred to as LWC) is usually provided as a multi-stage LWC package in which a plurality of LWCs are arranged so that their axial directions are vertical as shown in FIG. Is done. In FIG. 10, 10 is a multi-stage stacked LWC package, 11 is an LWC, 8 is a plate material (such as donut paper as a buffer material) that partitions the multi-stage LWC, 12 is a guide for guiding the pipe 2 when unwinding the LWC, Reference numeral 13 denotes a pallet on which LWC is loaded.

このような多段積みＬＷＣ梱包体１０のＬＷＣ１１を巻き解く場合、特許文献１〜３で示されるように、最上段にあるＬＷＣ１１の巻き解き開始の管端は、通常、巻回の容易なこと、および管端の取り出しの容易なことからＬＷＣ１１の最内周の上面または下面に設けられている。   When unwinding the LWC 11 of such a multi-stage LWC package 10, as shown in Patent Documents 1 to 3, the tube end of the unwinding start of the LWC 11 at the uppermost stage is usually easy to wind, In addition, since the tube end can be easily taken out, it is provided on the upper or lower surface of the innermost circumference of the LWC 11.

特開２００４−２３１３４８号公報JP 2004-231348 A 特開２００４−１４２８５４号公報JP 2004-142854 A 特開２００５−１２６１９８号公報JP 2005-126198 A

しかしながら、特許文献１の図７、特許文献２の図６、特許文献３の図６のように、ＬＷＣの巻き解き終了の管端が、ＬＷＣの最外周に位置し、その最外周の管がＬＷＣの上から下へ巻回されている場合、ＬＷＣの下面レベルに到達していないと巻回された管は、下にずり落ちる可能性が高く、したがって、管表面を傷つけたり、管そのものが折れたりしてしまう恐れがある。このような品質の低下を防止するためには、最外周の管がＬＷＣの上から下へ巻回される場合において、ＬＷＣの下面レベルに管が到達しないことが明らかなときは、その前の奇数層の下面レベルに管が到達した時点で、管の巻回を終了し、残りの管は切断してしまう必要があり、それゆえ歩留まりの低下を招く結果となる。   However, as shown in FIG. 7 of Patent Document 1, FIG. 6 of Patent Document 2, and FIG. 6 of Patent Document 3, the end of the unwrapping of the LWC is located at the outermost periphery of the LWC, and the outermost peripheral tube is When the LWC is wound from the top to the bottom, the wound tube is likely to slide down if the lower surface level of the LWC is not reached. Therefore, the tube surface is damaged or the tube itself is broken. There is a risk that. In order to prevent such deterioration in quality, when the outermost tube is wound from the top to the bottom of the LWC, when it is clear that the tube does not reach the lower surface level of the LWC, When the pipe reaches the lower level of the odd layer, the winding of the pipe must be terminated and the remaining pipes must be cut, resulting in a decrease in yield.

また、特許文献１から特許文献３で提案されるＬＷＣの構造では、図８に示すようにターンテーブルを用いないで管を巻き解く、ターンテーブル不使用方式による巻き解き方法を採用し、管を内側の管端から巻き解く場合には、ＬＷＣの管の巻層の数は奇数層にすることが好ましいという制約ができてしまい、これも余分な管の発生原因となってしまう。
更に、管を内側の管端から巻き解く場合、ＬＷＣの内径が変化する。そのため、巻き解きの途中で管の不良が発見された際、残りのＬＷＣは把持具で持ち上げ、廃棄することになるが、ＬＷＣを内側から押し付けて持ち上げるタイプの把持具で押圧把持することが困難になるために、ＬＷＣの廃棄が困難になってしまうという問題が生じる。 In addition, in the LWC structure proposed in Patent Document 1 to Patent Document 3, a tube unwinding method using a turntable-free method is employed in which the tube is unwound without using a turntable as shown in FIG. In the case of unwinding from the inner tube end, it is possible to restrict the number of winding layers of the LWC tube to be an odd number of layers, which also causes generation of extra tubes.
Furthermore, when unwinding the tube from the inner tube end, the inner diameter of the LWC changes. Therefore, when a tube defect is discovered during unwinding, the remaining LWC is lifted and discarded by the gripping tool, but it is difficult to press and hold with a gripping tool that pushes the LWC from the inside and lifts it. Therefore, there arises a problem that it becomes difficult to discard the LWC.

本発明は、このような状況に鑑みなされたもので、いかなる長さの管であっても、その管が健全である限り、高い歩留まりで管を巻回することができ、且つ管の不良が発見された際に残りのＬＷＣの廃棄が容易なＬＷＣ、ＬＷＣ梱包体およびＬＷＣ巻き解き方法を提供するものである。   The present invention has been made in view of such a situation. As long as the pipe is healthy, the pipe can be wound at a high yield as long as the pipe is healthy. It is intended to provide an LWC, an LWC package, and an LWC unwinding method that can easily discard the remaining LWC when discovered.

図を参照して本発明の実施形態を具体的に説明する。
図１は、本発明の第一の実施形態を示す縦断面図である。図１において、１はＬＷＣ（レベルワウントコイル）、２は管、３は最外周（第１周）に位置する管、３ａは巻き解き開始の管端、４は第２周に位置する管、５は第３周に位置する管、６は第４周に位置する管、６ａは巻き解き終了管端、６６は第４周に位置する管、７は第５周に位置する管、７ａは巻き解き終了管端、１００はＬＷＣの下面レベル、１０１はＬＷＣの上面レベルである。
図１（ａ）は、５周からなるＬＷＣ１で、管７が最内周管で、下面レベル１００から巻回されている。図１（ｂ）は、４周からなるＬＷＣ１で、管６６が最内周管で、上面レベル１０１から巻回されている。 An embodiment of the present invention will be specifically described with reference to the drawings.
FIG. 1 is a longitudinal sectional view showing a first embodiment of the present invention. In FIG. 1, 1 is an LWC (level-wound coil), 2 is a pipe, 3 is a pipe located on the outermost circumference (first circumference), 3a is a pipe end of unwinding start, and 4 is a pipe located on the second circumference. 5 is a pipe located on the third circumference, 6 is a pipe located on the fourth circumference, 6a is an unrolled pipe end, 66 is a pipe located on the fourth circumference, 7 is a pipe located on the fifth circumference, 7a Is the unwound end pipe end, 100 is the lower surface level of the LWC, and 101 is the upper surface level of the LWC.
FIG. 1A shows an LWC 1 consisting of five turns, and the tube 7 is the innermost tube and is wound from the lower surface level 100. FIG. 1B shows an LWC 1 having four turns, and the pipe 66 is the innermost pipe and is wound from the upper surface level 101.

通常、管を巻回してＬＷＣを作製する場合、ＬＷＣの内周の管から巻回が始められ、供給された長さを巻回して終了するが、最外周の管が外周の上面レベルから下面レベル方向に巻回され、且つ下面レベルに到達していない場合には、ＬＷＣの保管時や管の巻き解き時に、管のずり落ちなどが生じて管を損傷させる恐れが多くなることから、先の上面レベルの位置で管の巻回をやめて管を切断する。したがって、残りの管は余剰となってしまう。   Normally, when an LWC is manufactured by winding a tube, the winding starts from the inner tube of the LWC and ends by winding the supplied length, but the outermost tube is turned from the upper surface level of the outer surface to the lower surface. If it is wound in the direction of the level and has not reached the lower surface level, the pipe may fall off when the LWC is stored or the pipe is unwound, and the pipe may be damaged. At the position of the upper surface level, stop winding the tube and cut the tube. Therefore, the remaining pipes become redundant.

これに対し、本実施形態に係るＬＷＣ１は、図１（ａ）、（ｂ）で示すように、最外周管３は、必ずＬＷＣ１の下面レベル１００から巻回されているので、ＬＷＣの保管時や管の巻き解きにおいて、最外周の管のずり落ちによる管の損傷は生じない。また、本実施形態のＬＷＣ１は、最外周の管が天板方向に巻回されているため、図８に示すように最外周の管端からスムーズに巻き解くことができる。
なお最内周の管について、最外周の管端から巻き解きたいときには、最後に巻き解かれることになるので、管のずり落ち防止のために、管端が底板９ｂ側にあることが望ましい。更に、このような場合のＬＷＣ１の内径は、巻き解きの間では変わらない。したがって、管の巻き解きの途中で管に不良が発見された場合には、最内周の管側にＬＷＣ１の内側から押し付けるタイプの把持具を押し付けて持ち上げ、ＬＷＣ１を廃棄することが容易である。 On the other hand, in the LWC 1 according to the present embodiment, as shown in FIGS. 1A and 1B, the outermost peripheral tube 3 is always wound from the lower surface level 100 of the LWC 1, so that the LWC is stored. In unwinding the tube, the tube is not damaged by the slipping of the outermost tube. Further, since the outermost tube is wound in the top plate direction, the LWC 1 of the present embodiment can be smoothly unwound from the outermost tube end as shown in FIG.
When the innermost tube is to be unwound from the outermost tube end, it is unwound at the end. Therefore, it is desirable that the tube end is on the bottom plate 9b side in order to prevent the tube from slipping off. Further, the inner diameter of the LWC 1 in such a case does not change during unwinding. Therefore, when a defect is found in the tube during the unwinding of the tube, it is easy to press and lift a gripping tool of the type that is pressed from the inside of the LWC 1 to the innermost tube side, and discard the LWC 1 .

図２は、本発明の第二の実施形態に使用される支持部材の説明図である。図２において、９ｂは底板、１３はパレット、２２は支持部材、２２ａ〜２２ｄは支持部材の実施例の一例を示すもので、各支持部材は、ＬＷＣ１の内面１ａに沿うように置かれ、２２ａは円筒形、２２ｂ、２２ｃは多角中空体、２２ｄは方形シートを丸めた切欠き円筒形の支持部材である。   FIG. 2 is an explanatory view of a support member used in the second embodiment of the present invention. In FIG. 2, 9b is a bottom plate, 13 is a pallet, 22 is a support member, 22a to 22d are examples of support members, and each support member is placed along the inner surface 1a of the LWC 1, and 22a Are cylindrical hollow bodies, 22b and 22c are polygonal hollow bodies, and 22d is a notched cylindrical support member obtained by rounding a rectangular sheet.

本実施形態では、図２に示すように、ＬＷＣ１の内側にボビンを有しない、いわゆるボビンレスのＬＷＣ１を用いている。ボビンが不必要であることから、樹脂成形品であるボビン掛かるコストを削減することが可能となるが、ボビンによるＬＷＣ１の構造を支持できる効果がその分損なわれることになる。そこで、図２に示すような簡単な支持部材２２ａから２２ｃを代わりに用い、これをＬＷＣ１の内側に矢印に示すように挿入し、ＬＷＣ１を内側から支持することで、ＬＷＣ１の構造が崩れることを防止することができる。
また、本実施形態では、最外周から管を巻解くので、最後に最内周の管を巻解くことになる。支持部材２２ａから２２ｃは、このように最後に残った最内周の管を支持するので、管のずり落ちと、それによる管の表面に傷が入ることを防止することができる。 In this embodiment, as shown in FIG. 2, a so-called bobbin-less LWC 1 that does not have a bobbin inside the LWC 1 is used. Since the bobbin is unnecessary, it is possible to reduce the cost of the bobbin that is a resin molded product, but the effect of supporting the structure of the LWC 1 by the bobbin is impaired accordingly. Therefore, instead of using the simple support members 22a to 22c as shown in FIG. 2 and inserting them into the LWC1 as shown by the arrows, and supporting the LWC1 from the inside, the structure of the LWC1 is destroyed. Can be prevented.
In this embodiment, since the tube is unwound from the outermost periphery, the innermost tube is finally unwound. Since the support members 22a to 22c support the innermost peripheral pipe remaining at the end in this way, it is possible to prevent the pipe from slipping and thereby causing damage to the surface of the pipe.

図３は、他の支持部材を示す説明図である。図３において、緩衝材８（例えば紙ダンボール製）に十字スリット８ａを設け、そこに２枚の矩形ダンボール片２２０ｅを十字に組み合わせてなる十字形支持部材２２ｅを取り付けたものである。
このような構成によれば、非常に簡易に組み立て可能な支持部材２２により、最内周の管を支持することができ、好ましい。 FIG. 3 is an explanatory view showing another support member. In FIG. 3, a cross-shaped slit 8a is provided in a cushioning material 8 (for example, made of paper cardboard), and a cross-shaped support member 22e formed by combining two rectangular cardboard pieces 220e in a cross shape is attached thereto.
According to such a configuration, the innermost tube can be supported by the support member 22 that can be assembled very easily, which is preferable.

図４〜図７は、先に示した支持部材２２を用いた実施形態に係るＬＷＣ梱包体の縦断面図である。図４は、円筒形支持部材２２ａを用いた場合、図５は、多角中空体２２ｃを用いた場合、図６は、切欠き円筒形支持部材２２ｄを用いた場合、図７は十字形支持部材２２ｅを用いた場合を示している。なお、図４中の符号９ａは天板を示す。
支持部材２２ａ〜２２ｅは、二つのＬＷＣ１に跨って設けられる。そのため、輸送中に加わる振動によるＬＷＣ１の位置ずれを防止できる。更に、巻き解き作業時では、巻き解きを行うＬＷＣ１の下面レベルに支持部材２２の端を移動させることで、巻き解きによる管の崩れを防止する。 FIGS. 4-7 is a longitudinal cross-sectional view of the LWC package which concerns on embodiment using the supporting member 22 shown previously. 4 shows a case where a cylindrical support member 22a is used, FIG. 5 shows a case where a polygonal hollow body 22c is used, FIG. 6 shows a case where a notched cylindrical support member 22d is used, and FIG. The case where 22e is used is shown. In addition, the code | symbol 9a in FIG. 4 shows a top plate.
The support members 22a to 22e are provided across the two LWCs 1. Therefore, it is possible to prevent the LWC 1 from being displaced due to vibration applied during transportation. Further, at the time of unwinding work, the end of the support member 22 is moved to the lower surface level of the LWC 1 to be unwound to prevent collapse of the tube due to unwinding.

図８に示すように本実施形態のＬＷＣ４１は、ターンテーブル不使用方式で最外周から巻き解かれる。なお、この場合、巻き方によっては底板４４（若しくは緩衝材４４）に接した管が、それより１つ上の管と挟まれて巻き解くことが困難になる場合が生じる。
表１は、ターンテーブル不使用方式において、管を最外層の管端から巻き解く場合に好ましい層構成とＬＷＣの置き方の組み合わせ（表１中で好適と表記）、及びその逆の好ましくない組み合わせ（表１中で非好適と表記）を示すものである。 As shown in FIG. 8, the LWC 41 of this embodiment is unwound from the outermost periphery in a turntable non-use method. In this case, depending on the winding method, it may be difficult to unwind the tube in contact with the bottom plate 44 (or the buffer material 44) by being sandwiched by the tube one above it.
Table 1 shows the preferred combination of layer structure and LWC placement (noted as preferred in Table 1) when unwinding the pipe from the outermost pipe end in the turntable non-use method, and vice versa. (Denoted as unpreferable in Table 1).

Figure 2007153601

表１において、「Ｎ−１巻」と表示したものは、図９（ａ）に示すように、ＬＷＣの整列巻において、最内層をＮ回巻いた構成としたときに、その一つ外側をＮ−１回巻き、それを外側の層に向かうごとに繰り返す構成である。「Ｎ巻」、「Ｎ＋１巻」（図９（ｂ）参照）も同様に巻き数を変えたものである。なお、Ｎ巻の場合は、巻き取り時にフランジ側で折り返す場合（表１中、フランジ側折り返し、図９（ｄ）参照）と、フランジ側とは逆側に折り返す場合（表１中、管側折り返し、図９（ｃ）参照）がある。
このように、できるだけ表１において、好適とされる組み合わせの配置を採用することで、管の巻き解きを効率よく行うことができ、管に対する損傷も少なくてすむものである。
以上説明したように、本発明によれば、いかなる管の長さであっても、その管が健全である限り、高い歩留まりで管を巻回することができ、且つ管の不良が発見された場合に、残りのＬＷＣの廃棄が容易なＬＷＣ、ＬＷＣ梱包体およびＬＷＣの巻き解き方法を提供することができる。 In Table 1, "N-1 roll" is indicated as shown in Fig. 9 (a). In the LWC aligned winding, when the innermost layer is wound N times, one of the outer sides is indicated. This is a configuration in which N-1 turns are repeated each time it goes to the outer layer. “N roll” and “N + 1 roll” (see FIG. 9B) are also the same in which the number of turns is changed. In the case of N windings, when winding back on the flange side during winding (refer to FIG. 9 (d), flange side folding in Table 1), or when folding back to the opposite side of the flange side (Table 1, pipe side) Folded, see FIG. 9 (c)).
In this way, by adopting a suitable combination arrangement in Table 1, the unwinding of the tube can be efficiently performed, and damage to the tube can be reduced.
As described above, according to the present invention, as long as the tube is healthy, the tube can be wound with a high yield as long as the tube is healthy, and a defective tube has been found. In this case, it is possible to provide an LWC, an LWC package, and an LWC unwinding method that can easily discard the remaining LWC.
