Description

  The present invention relates to a bobbin for winding a wire such as an optical fiber cable.

  Bobbins are used for storing and transporting wires such as optical fiber cables and coaxial cables. The bobbin is usually made up of a cylindrical body part for winding the wire, and flanges provided at both ends of the body part.

  For example, in Patent Document 1, convex pieces are provided at both end edges of a cylindrical body, an engagement hole is provided at a position corresponding to the convex piece of the flange, and the convex piece is engaged with the engagement hole. There has been proposed a paper bobbin formed by joining a joined body to the tip of a protruding piece projecting outside the portion.

A disadvantage of such conventional bobbins is that they cannot be quickly assembled and disassembled. In other words, when wire is attached to the bobbin, it can help to reduce the cost of storing and transporting the bobbin to the site by quickly assembling it at the wire factory, etc.When the wire is unwound from the bobbin at the construction site, etc. However, space saving can be achieved by quickly disassembling and downsizing. However, the conventional bobbin as shown in Patent Document 1 cannot be quickly assembled and disassembled in this way because of its complicated structure. there were. In addition, when the bobbin shown in Patent Document 1 is disassembled, both flange portions are separated, so that it is difficult to handle when reassembling, and one of them may be lost. In particular, since a relatively expensive material is usually used for the buttocks to provide sufficient strength, it is strongly desired to reuse the material, so it is desirable to prevent such a situation as much as possible.

It is also possible to connect the flange portions 10 by forming a flat hole by being sandwiched between the outer flange 11 and the inner flange 13 and inserting the bent portion 31 into the flat hole. The plate-like member 30 is preferably formed by bending both ends of a strip-shaped corrugated cardboard substantially at a right angle for simple and low cost.

  Further, as shown in FIG. 7, both end portions 41 of the support column 40 are attached to the both flange portions 10. By doing in this way, the intensity | strength of the bobbin 1 can be increased easily. The column 40 is attached by detachably fitting both ends of the column 40 in a through groove formed by overlapping engagement grooves 13b and 12b provided in the inner flange 13 and the intermediate flange 12. It is preferable that the support column 40 is formed simply by bending a strip-shaped cardboard at the center in the longitudinal direction at a low cost.

  Finally, as shown in FIG. 8, both end edges 52 of the band-like member 51 with a large number of broken lines 58 are connected to the peripheral edges of the small-diameter portion composed of the middle collar 12 and the inner collar 13 of both collar sections 10 connected by the wire 20. 9 is bent along a fold line 58 and rolled into a substantially cylindrical shape, and both side edges 53 are detachably joined to form a body portion 50 as shown in FIG. Complete. The joining between the side edges 53 is performed by a hook-and-loop fastener 54 attached to the side edges 53. The surface fastener 54 can be replaced by other removable attaching means such as an adhesive tape and an adhesive. By forming the bobbin 1 in this way, the wire 20 sandwiches the body portion 50 with a force that pulls the both flange portions 10, so there is no need to tighten or bond the flange portion 10 and the body portion 50 with bolts. Therefore, decomposition can be performed with almost one behavior. In addition, it is preferable that the material of the strip | belt-shaped member 51 uses a cardboard. In addition, the belt-like member 51 may be a single-use type that is incinerated for disposal every time it is disassembled.

  The bobbin 1 formed in this way can be disassembled in almost one behavior after use by unbonding the side edge 53 of the body portion 50 and removing the support column 40 from the flange portion 10. At this time, the column 40 is fitted into the flange portion 10, the body portion 50 is wound and the side edges 53 are joined, so that the assembly can be performed with almost one behavior, so that the bobbin can be easily assembled and disassembled. Here, since the collar part 10 is integrally connected by the wire 20, it is easy to handle when reassembling and there is no fear of losing it, which is convenient.

  In addition to this embodiment, the body portion 50 is formed by connecting the two side edges 56 of the semi-cylindrical connecting member 55, which connect one side edges of the two semi-cylindrical parts, as shown in FIG. You may form by bonding together by 54 grade | etc.,. In this case, since the trunk | drum 50 is robust, the support | pillar 40 does not need to be provided. In this case as well, the bobbin 1 can be assembled and disassembled with one behavior by joining and dissociating the side edges 56 of the semi-cylindrical connecting member 55.

  Further, by making the diameter of the intermediate collar 12 smaller than that of the inner collar 13, in the case of FIG. 6, it is in the same state as the notch 12d formed on the entire circumference, as shown in FIG. By connecting a plurality of small pieces 57 corresponding to the broken line 58 at both end edges 52 of the belt-like member 51, the belt-like member 51 can also have a role as a connecting member in addition to the role as the trunk portion 50. it can. In other words, the small piece 57 of the belt-like member 51 is bent at a substantially right angle and is sandwiched between the outer collar 11 and the inner collar 13 so that it is inserted into the recess formed over the entire circumference of the inner collar 12 and is ended on the periphery of the inner collar 13. Bending along a fold line 58 while abutting the edge 52, it is rolled into a substantially cylindrical shape, and both side edges 53 are detachably joined to each other, thereby completing a bobbin that can be easily assembled and disassembled without requiring a separate connecting member.
