[Detailed Description of the Invention] The present invention relates to an assembly reel for a long coil-wound copper pipe.

たとえば、冷暖房機器に使用される冷媒の流通
用の銅管はその直径が10mm前後と比較的小さい

便を考えると、分解、組立が自由な組立式としな
ければリールの占有空間のみが大となり、結果的
には極めて不経済となつてしまうからである。
For example, copper pipes for circulating refrigerant used in heating and cooling equipment have a relatively small diameter of around 10 mm, but are shipped wound into coils to be supplied to users. This coiled copper tube is fitted onto an assembly type reel and supplied. The reason for this is that when the copper pipe is used up, the empty reel cannot be disposed of from an economical point of view and is used many times, so it is difficult to disassemble and reassemble it for convenience in transportation and storage. This is because if the reel is not freely assembled, the space occupied by the reel will be large, resulting in extremely uneconomical results.

ところで、銅管を例えば数百m巻きつけたコイ
ル巻銅管は巻き上がつた後、焼鈍が行なわれる等
の理由によりコイル巻銅管の巻き内径の変化が生
じてしまい、内径が楕円状になつたり個々のコイ
ル巻銅管の巻き内径が異なる結果となる。
By the way, the inner diameter of a coiled copper tube that has been wound, for example several hundred meters, changes due to reasons such as annealing after being wound, resulting in an elliptical inner diameter. This results in different inner diameters of the individual coiled copper tubes.

一方、このように個々に内径の異なるコイル巻

On the other hand, if the diameter of the barrel of the reel into which coiled copper tubes with different inner diameters are fitted is constant and matched to the coiled copper tube with the smallest inner diameter, then this barrel When a coiled copper tube is fitted into a cylinder and attached to an uncoiler and fed intermittently in fixed length increments, the gap between the body tube and the coiled copper tube causes the coiled copper tube to move against the axis of the uncoiler. It slips and cannot be rotated, and since the copper tube is being pulled by the feeder, a large amount of tension is applied to the copper tube, which may cause the copper tube to be cut.
The diameter will change.

また、コイル巻銅管の中心孔が偏心している場
合には胴筒とコイル巻銅管との間に生じる隙間は
一方の側に片寄つて存在する。従つて、コイル巻
銅管の回転に伴なつて、この隙間が上方に位置す

あるため、隙間分だけコイル巻銅管が落下するこ
とになり、引き出される銅管に波打ち現象が生
じ、銅管自身が波打つたり、ゆるんだりする結果
となる。
Further, when the center hole of the coiled copper tube is eccentric, the gap created between the body tube and the coiled copper tube is biased to one side. Therefore, as the coil-wound copper tube rotates, if this gap moves upward, the coil-wound copper tube will fall by the amount of the gap because the coil-wound copper tube is extremely heavy. , a waving phenomenon occurs in the drawn-out copper tube, resulting in the copper tube itself waving or becoming loose.

In addition, when the copper tube becomes loose, this loosening is transmitted to the coiled copper tube in turn, causing the coiled copper tube to become loose, and part of the copper tube gets wedged between the side plate of the reel and the coiled copper tube. It becomes stuck and cannot be pulled out, resulting in breakage or deformation of the stretched copper pipe.

Furthermore, when copper tubes are wound in an aligned manner, there will always be areas where the upper-layer copper tube crosses and climbs over the lower-layer copper tube, and this portion bulges outward, resulting in an overall eccentricity of the coil-wound copper tube. occurs, the weight is uneven,
If there is a gap between the coil-wound copper pipe and the body when it rotates, intermittent slips will occur in the coil-wound copper pipe.
This can result in excessive tension being applied to the copper pipes, causing them to loosen or become deformed.

First, one side plate 2 is placed in a horizontal state, and the barrel tube 4 is placed on the side plate 2 using the outer peripheral edge of the protruding portion 5 as a guide for positioning. In this state, the coiled copper tube 6
is fitted to the outside of the barrel tube 4. Next, the other side plate 3
is placed on the barrel tube 4 in a horizontal state so that the tapered surface 5a of the protrusion 5 fits inside the barrel tube 4, and the wedge action of the tapered surface 5a moves the barrel tube 4 toward the side with the larger diameter. Attach by pushing it apart. After this, the pair of side plates 2 and 3 are firmly connected by a fastening band 7 made of a steel belt or the like through the through holes 2b and 3b formed at positions corresponding to the inside of the body tube 4 of each side plate 2 and 3. Link. Due to the fastening force of the both side plates, the barrel tube 4 is pushed out in the direction of increasing its diameter by sliding between its upper and lower edges and the tapered surface 5a, and the barrel tube 4 is securely attached to the inner circumferential surface of the coiled copper tube 6. Pressed. As a result, errors in the inner diameter of the coiled copper tube 6 and deformations such as elliptical shapes are absorbed, and there is no misalignment between the body tube 4 and the coiled copper tube 6.

The coil-wound copper tube is shipped in this state, and during bundling, the disk-shaped side plates 2 and 3 can be used to roll and move the coil-wound copper tube. Since there is no gap between the barrel tube 4 and the coiled copper tube 6 when feeding the coiled copper tube one by one, the above-mentioned inconvenience in handling the copper tube does not occur. After using all the wound copper tubes, the fastening band 7 is removed, the left and right side plates 2 and 3 and the body tube 4 are disassembled, and the side plates 2 and 3 are stacked on top of each other, and the body tube 4 is removed. If they are located separately, the space in which they are accommodated is significantly reduced in size, allowing a large number of reels to be accommodated in a small space, which is extremely advantageous for transportation and storage.
