組立リールに関する。[Detailed Description of the Invention] The present invention relates to an assembled reel for long coil-wound copper pipes, and more specifically, the inner diameter of the coil-wound copper pipe may be deformed or misaligned due to heat treatment of the long coil-wound copper pipe. The present invention relates to an assembly reel for a long coil-wound copper tube, in which the outer circumferential surface of a cylindrical body can uniformly and strongly press the inner circumferential surface of the coil-wound copper tube to reliably hold the copper tube in a rotationally immovable manner.

管、取扱等がなされている。 Copper pipes, which have been widely used in heating and cooling equipment, have a relatively small diameter and a large wall thickness.
Because it is extremely thin at 0.35 mm or 0.28 mm, it is wound into a coil and stored in a reel for transportation, storage, and handling.

り、切断する等の不都合を生じる。 However, with this type of reel, if the inner diameter of the coiled copper tube is deformed into an oval shape or the like due to the winding process or subsequent heat treatment, a gap will form between the inner circumferential surface of the coiled copper tube and the outer circumferential surface of the barrel. When the uncoiler feeds a fixed length intermittently, this gap causes rotation due to misalignment and creates a slack between the uncoiler and the feeder, and the copper tube that is being uncoiled with excessive tension on the uncoiler side may become unreeled. This may cause inconveniences such as it coming off or being cut.

Therefore, when an external force is applied to the outside in the radial direction, the diameter expands, and it is configured to have a large rigidity against external force applied in the axial direction. The diameter of the circle formed by connecting the tops of the chevron portions 11 is slightly smaller than the minimum inner diameter of the coiled copper tube 8.

く押圧し、銅管８を回転不動に固定させている。 Coiled copper pipes wound to a predetermined diameter at a pipe manufacturing factory are usually deformed into an oval shape or misaligned due to the winding process or heat treatment such as annealing. In order to fit such a coil-wound copper tube 8 to a reel,
First, the side plate 2' is placed horizontally with its protruding disk 4' facing upward. Next, the cylindrical body 3 according to the present invention
is placed on the side plate 2' using the tapered surface 5' formed on the outer peripheral edge of the protruding disk 4' as a guide.
Next, the coiled copper tube 8, which has been deformed into an oval shape or the like as described above and is not necessarily a perfect circle, is fitted onto the outer peripheral surface of the body 3 and placed on the side plate 2'. In this state, a gap is created between the coiled copper tube 8 and the body 3 due to deformation, positional displacement, or the like. Next, place the other side plate 2 with the surface on which the protruding disk 4 is formed facing downward, and align the upper end surface of the body 3 so that the outer edge of the tapered surface 5 of the protruding disk 4 is placed on the inner edge of the body 3. Place it on. Then, when the side plate 2 is lightly pressed from above and the fastening band iron 9 is tightened between the side plates 2 and 2' through the through hole 7, the tapered surfaces 5 and 5' are moved from the outer edge to the inner edge. While in contact with the inner edge of the body 3, it gradually slides (wedge effect), expands the corrugated body 3 radially outward, and creates a space between the inner circumferential surface of the coiled copper tube 8 and the outer circumferential surface of the body 3. At the same time, the angular portion 11 of the body 3 comes into contact with the inner circumferential surface of the coiled copper tube 8 and presses it with an appropriate pressure. In this state, the fastening band iron 9 is fastened to fix the coiled copper tube 8 between the side plates 2 and 2'. In this state, all of the chevrons 11 of the corrugated body 3 strongly press against the inner circumferential surface of the coiled copper tube 8, fixing the copper tube 8 so as not to rotate.

い態様である。 In the above embodiment of the present invention, the side plates and the protruding disk were made of the same material, but the present invention is not limited to this. For example, the side plates 2 and 2' are made of thin metal plates and made of synthetic resin. Alternatively, a protruding disk may be attached to form an integral structure. In addition, both side plates 2,
2' is fastened with a band iron 9, but it is not limited to this, and for example, bolts and nuts for fixing the side plate may be used. Furthermore, the wavy shape formed on the side wall 10 of the cylindrical body 3 may be such that the width of the trough portion 12 is smaller than that of the chevron portion 11, and the outer peripheral surface may be formed in an arc shape. As shown in the partially enlarged view of FIG. 3a, the valley-shaped portion 12 of the cylindrical body 3 can be tapered to match the tapered surface having an inclination angle formed on the protruding disks 4, 4'. This is a preferred embodiment.

てもすぐれた利点を有する。 As described in detail above, the assembly reel 1 for long coil-wound copper pipes of the present invention has disc-shaped protruding discs 4, 4' integrally formed at the center of one side of the side plates 2, 2', and Tapered surfaces 5, 5' are formed on the outer peripheral edges of the protruding disks 4, 4', and the side plates 2,
By forming a large number of corrugated shapes 13 in the axial direction of the side wall of the body 3 held between the 2' and 2', the diameter of the body 3 is expanded against external forces in the radial direction, and the body 3 has a large rigidity against external forces in the axial direction. Since it was configured to have
Even if the coiled copper tube 8 is deformed, the coiled copper tube 8
There is no gap between the inner circumferential surface and the outer circumferential surface of the body 3, and the coiled copper tube 8 can be reliably held by the strong pressing force of the chevron portion 11 of the body 3. Even if the pipe 8 repeatedly falls down to the body 3 due to its own weight each time it rotates during the unwinding process, no corrugations will be formed in the copper pipe, and furthermore, the unwinding process will be prevented due to misalignment of the coiled copper pipe 8. It is extremely convenient to handle, as there is no rotation occurring inside the pipe and the sending copper pipe is not pulled strongly, and no slack is formed between the uncoiler and the feeder, and the body 3 is strong in the axial direction. Because of its rigidity, it has excellent advantages in terms of transportation, storage, and handling, such as not causing deformation even if the reels are stacked for a long period of time or are handled roughly during transportation.
