[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention is for a flexible linear body such as a flexible pipe, a cable or a wire used for wiring or plumbing, which is used to wind and pull out a so-called flexible linear body. The present invention relates to an improved reel structure.

[0002]

[Prior Art]

 In the past, in the piping work of flexible conduits (PF pipes) made of synthetic resin and CD pipes used in, for example, electrical work, it has been a time-consuming and troublesome work to stretch these pipes. In addition, due to the nature of PF pipes and CD pipes, it is difficult to stretch them smoothly, let alone between pipes that are laid when laying at the construction work site. It required at least two workers, one for piping and one for extending the pipe from the reel and supplying it.

Conventionally, as a reel for a cable which is commercially available and used, for example, a foldable “chochin reel” is known. Due to its structure, this reel is a so-called pipe insertion method in which a linear body is drawn inside from between the outer frame holding bodies and wound around the outer circumference of the reel, and a flexible pipe or cable wound around the reel is used. You can only pull out one by one. Therefore, if you want to pull out multiple PF tubes or CD tubes at the same time, you must prepare the same number of reels as those tubes, which makes it difficult to move them at work sites with poor footing. It was a loss.

[0004]

[Problems to be solved by the device]

 That is, in the above-mentioned conventional technique, when performing piping work at a construction site, it is difficult to pull out and extend several pipes from one reel at a time. The use of the chochin reel did not significantly reduce the time and labor required for piping work and the number of workers. In addition, some reels have variable winding diameters, but when piping multiple types of pipes and cables at the same time, multiple reels had to be prepared, which was extremely inconvenient for work.

In view of the above problems in the prior art, the present invention makes it easy to pull out the flexible linear body from the reel, the winding diameter of the flexible linear body is variable, and a plurality of reels are arranged on the same reel. It is an object of the present invention to provide a reel for a flexible linear body, which can be individually wound around the flexible linear body, and is convenient for piping work.

It is composed of a protruding separator plate 302. That is, as shown in FIG. 10, the fixing portion 301 has, for example, a plate curved at a radius substantially equal to that of the circular frame 21 and has substantially triangular shapes at both ends thereof, and the cutouts 303, 303 from the apex thereof. Are formed, and these triangular portions are bent inward. Then, the drum bar 24 is fitted and fixed in the cutout grooves 303, 303. Then, when the flexible linear body 100 is wound from above, as shown in FIG. 10, the flexible linear body 100 wound from above hits the outer circumference of the flexible linear body 100, and the fixing portion 301 is pressed from the outer circumferential portion. Since it is pushed inward, it is securely fixed. Therefore, the protrusion angle of the tongue-shaped separator plate 302 is prevented from swinging to the left or right after the flexible linear body 100 is once wound around the outer periphery thereof.

Further, in the embodiment shown in FIG. 9, a retaining metal fitting 304 formed by folding a flat plate at 90 degrees is further used. That is, as also shown in the figure, the stopper metal fitting 304 is provided with a groove 305 (in this embodiment, the upper and lower fixing portions 301 in this embodiment) formed in a part of the cutout groove 303 formed in the fixing portion 301 of the separator 30. , 301) and thus the separator 30 is fixed on the drum bar 24. Further, in the separator 30 shown in FIG. 9, a hole 306 (for example, about 10φ) is formed at the tip of the separator plate 302, and it is possible to temporarily fix the tip of the wire by using these holes. Becomes Furthermore, a plurality of holes (for example, a total of four holes on the upper and lower surfaces) 307 and 307 can be formed in the fixing portion 301 of the separator 30, and similarly, the wire can be used for drawing.

By disposing such a separator 30 on the drum bar 24, it is possible to divide the winding layer above and below the drum bar 24. That is, even in the case of a plurality of types of flexible linear bodies 100, the flexible linear bodies 100 are wound around the circumference of the drum bars 24, 24 ... (Four in this embodiment), and are separated by the separators 30, 30. It becomes possible to wind it. This makes it possible to wind multiple types of flexible linear bodies individually and in parallel on the drum bar, which is extremely convenient for the work of piping various pipes and cables.

Further, in the separator 30 described above, as shown in FIG. 11 attached, the bent portion is gradually curved to form the linear body 100 such as a pipe wound around the outer circumference thereof. It is possible to install without. Also, in this embodiment, the tongue-shaped separator plate 302 is mounted on the outer periphery of the fixed portion 301 such that the distances L ₁ and L ₂ from the ends are not equal, for example, L ₁ > L _2. ing. The separator 30 can be attached in any desired direction.
