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. It is related with the level-wound-coil package body comprised by the level-wound coil arrange | positioned so that the axial direction may become perpendicular | vertical, and it may be unwound.

レベルワウンドコイル（Ｌｅｖｅｌ Ｗｏｕｎｄ Ｃｏｉｌ：以下、ＬＷＣと称す）は、通常、図１１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１１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. 11, 10 is a multi-tiered LWC package, 11 is an LWC, 8 is a plate material (such as donut paper serving as a buffer material) that partitions the multi-tiered LWC, and 12 is a guide for guiding the pipe 2 when unwinding the LWC, Reference numeral 13 denotes a pallet on which LWC is loaded.

多段積みＬＷＣ梱包体のＬＷＣを巻き解く場合、上段にあるＬＷＣの管端を取り出して、そのＬＷＣを巻き解かしていく。上段のＬＷＣの巻き解かしが終了したら、上段に隣接して、その下側に置かれている次段のＬＷＣの管端を取り出して巻き解かし作業を行っていくが、個々のＬＷＣの管端が連結されていないために、ＬＷＣを巻き解くごとに、その作業を停止して、ＬＷＣの管端をガイドや加工機にセットしなくてはならず、作業性の面から、その改善が要求されていた。   When unwinding the LWC of a multi-stage LWC package, the tube end of the LWC in the upper stage is taken out and the LWC is unwound. When the unwinding of the upper LWC is completed, the tube end of the next-stage LWC located below and adjacent to the upper row is taken out and the unwinding work is performed. Because it is not connected, every time the LWC is unwound, the work must be stopped and the tube end of the LWC must be set in a guide or a processing machine, and improvement is required from the viewpoint of workability. It was.

そこで、特許文献１では、上段のＬＷＣの巻き解かしが終わって、その管端部が上昇、又は上昇しようとした時に、管の供給を停止して、次段のＬＷＣとの間にある緩衝材を取り除き、前記次段のＬＷＣの巻き解き開始管端部にガイド冶具の錘を取り付け、この錘の作用で、上段の巻き解き終了管端部と次段のＬＷＣの巻き解き開始管端部を接続器具により連結した後、管の供給を再開する方法が提案されている。   Therefore, in Patent Document 1, when the upper LWC is unwound and the end of the pipe rises or is about to rise, the supply of the pipe is stopped, and the cushioning material between the LWC of the next stage The weight of the guide jig is attached to the end of the unwinding start tube of the next-stage LWC, and the action of this weight causes the end of the unwinding end pipe of the upper stage and the unwinding start pipe end of the next-stage LWC to A method has been proposed in which the supply of the pipe is resumed after being connected by the connecting device.

また、特許文献２に示されるように、多段積みＬＷＣ梱包体の上段ＬＷＣの巻き解き終了管端部と次段のＬＷＣの巻き解き開始管端部を、先に接続部材で連結しておき、前記上段のＬＷＣとその下側に位置する前記次段のＬＷＣとの間に、前記接続部材が、通過できる程度の隙間をもたらす厚みを有するスペーサーを設けることで連続的に巻き解き作業を行うＬＷＣ積層体が提案されている。   In addition, as shown in Patent Document 2, the unwinding end pipe end of the upper LWC and the unwinding start pipe end of the next LWC are connected with a connecting member in advance, An LWC that continuously unwinds by providing a spacer having a thickness that allows the connecting member to pass therethrough between the upper LWC and the lower LWC positioned below the upper LWC. Laminates have been proposed.

しかしながら、先に示した特許文献１に係るＬＷＣ梱包体からの管の供給方法では、ＬＷＣを切り替えるごとに、管の供給を一時停止し、接続器具を用いて上段ＬＷＣと次段ＬＷＣの管端の接続を行い、しかる後に管の供給を再開するが、その管端の接続部位が、加工機若しくは管の送り装置の導入部分に到達した時に、再度、管の供給を停止してその接続部位を除去する必要がある。
即ち、ＬＷＣを一コイル巻き解くごとに、２度にわたる管供給の停止が生じ、且つ、そのたびに管の接続および接続部位の除去という作業が要求されるために、生産性を向上させることが難しい。また、管の接続からその接続部位を除去する迄の間、その進行状況を監視しなくてはならず、作業性に大きな影響を与えている。 However, in the pipe supply method from the LWC package according to Patent Document 1 described above, the pipe supply is temporarily stopped each time the LWC is switched, and the pipe ends of the upper LWC and the next stage LWC are connected using the connecting device. After that, the supply of the pipe is resumed, but when the connection part of the pipe end reaches the introduction part of the processing machine or the pipe feeding device, the supply of the pipe is stopped again and the connection part Need to be removed.
That is, every time the LWC is unwound by one coil, the tube supply is stopped twice, and the operation of connecting the tube and removing the connected portion is required each time, so that productivity can be improved. difficult. In addition, the progress of the connection must be monitored until the connection site is removed from the connection of the pipe, which greatly affects workability.

特許文献２で示されるＬＷＣ積層体では、第一に、ＬＷＣ間に接続部材が通過できる程度の厚みのスペーサーを設けなければならず、そのためＬＷＣ積層体の構成部品数が多くなり、作業の手間とコストを増加させる。第二に、軟質銅管のような軟らかい管を巻いたＬＷＣの場合などでは、上段のＬＷＣの重さで、次段のＬＷＣの上面に前記スペーサーの形状に沿った窪み若しくは変形を発生させてしまい、管を不良品にしてしまう問題が生じる。第三に、管端部の接続は、内周部にある巻き解き開始管端部と外周部にある巻き解き終了管端部とを接続部材で接続するために、その接続部材の長さが必然的に長くなってしまい、その取り扱いが不便となり作業性を低下させる。   In the LWC laminate shown in Patent Document 2, first, a spacer having a thickness that allows the connection member to pass between the LWCs must be provided, which increases the number of component parts of the LWC laminate, and the work is troublesome. And increase costs. Secondly, in the case of an LWC wound with a soft tube such as a soft copper tube, the upper LWC weighs, causing a depression or deformation along the shape of the spacer on the upper surface of the next LWC. As a result, there arises a problem of making the pipe defective. Thirdly, the connection of the pipe end portion is performed by connecting the unwinding start pipe end portion in the inner peripheral portion and the unwinding end pipe end portion in the outer peripheral portion with a connecting member. Inevitably, it becomes long and the handling becomes inconvenient and the workability is lowered.

このような状況に鑑み、本発明はなされたもので、スペーサーなどの余分な構成部品を追加せずに、製造コストを低減し、その生産性を向上させるレベルワウンドコイル梱包体を提供する。   In view of such a situation, the present invention has been made, and provides a level wound coil package that reduces manufacturing costs and improves productivity without adding extra components such as spacers.

請求項１記載の発明は、管を円筒状に巻回した少なくとも１段のレベルワウンドコイルを底板上に積層したレベルワウンドコイル梱包体であって、前記少なくとも１段のレベルワウンドコイルが、緩衝材を介して積層され、且つ、隣接するレベルワウンドコイルは、その最外層同士の管端、若しくは最内層同士の管端が、接続部材で連結されていることを特徴とするレベルワウンドコイル梱包体である。   The invention according to claim 1 is a level-wound coil package in which at least one level-wound coil obtained by winding a tube in a cylindrical shape is laminated on a bottom plate, and the at least one level-wound coil is a cushioning material. The level-wound coils that are stacked through and adjacent to each other are the level-wound coil packages in which the tube ends of the outermost layers or the tube ends of the innermost layers are connected by a connecting member. is there.

請求項２記載の発明は、前記接続部材が難透水性樹脂からなるチューブであることを特徴とする請求項１記載のレベルワウンドコイル梱包体である。   The invention according to claim 2 is the level-wound coil package according to claim 1, wherein the connecting member is a tube made of a hardly water-permeable resin.

本発明の係るレベルワウンドコイル梱包体は、積層されたレベルワウンドコイルの隣接コイル間をその内周同士の管端若しくは外周同士の管端で連結することにより、構成部品数を増加させることなく、又接続部材の長さも短くすることができ、その製造コストの低減に大きく寄与するものである。
更に、ＬＷＣの巻き解け作業時の管供給の停止も、接続部材を除去する時のみで良く、複数のＬＷＣを連続供給することができることから、その生産性を大きく向上させるものである。 The level-wound coil package according to the present invention connects the adjacent coils of the laminated level-wound coils at the tube ends between the inner peripheries or the tube ends between the outer peripheries without increasing the number of components. Further, the length of the connecting member can be shortened, which greatly contributes to the reduction of the manufacturing cost.
Furthermore, the pipe supply during the LWC unwinding operation can be stopped only when the connecting member is removed, and a plurality of LWCs can be continuously supplied, which greatly improves the productivity.
