Description

The present invention relates to a winding drum partition installation tool and a winding drum with a partition.

For example, a winding drum that winds up a linear body such as an optical fiber is known. It is also known that in such a winding drum, a partition is provided on the winding body, which is the part that winds up the linear body. In such a winding drum with a partition, the winding body is divided into a provisional winding section and a main winding section. For example, Patent Document 1 discloses such a winding drum with a partition.

Japanese Patent Application Publication No. 6-336366

When winding a linear body onto a partitioned winding drum as described above, first one end of the linear body is wound slightly onto the temporary winding section, and then most of the remaining linear body is wound onto the main winding section. In this way, one end of the linear body is exposed on the surface of the temporary winding section, and the other end is exposed on the surface of the main winding section, making it easy to access both ends of the linear body even after winding. If the linear body is, for example, an optical fiber, both ends of the optical fiber are exposed on the surface, making it easy to perform operations such as attaching optical connectors to both ends.

Since partitioned winding drums like the ones above are made to order, delivery times can be long, and it can be difficult to handle sudden increases in orders.

The object of the present invention is to provide a winding drum partition installation tool that can install a partition on a winding drum, and a winding drum with a partition that has the winding drum partition installation tool.

The following describes a partitioned winding drum according to a preferred embodiment of the present invention.

Figure 1A shows a perspective view of a partitioned winding drum 100. As shown in Figure 1A, the partitioned winding drum 100 has a winding drum 200 and a winding drum partition installation device 300.

The partitioned winding drum 100 can be obtained by attaching a winding drum partition installation tool 300 to the winding drum 200. Specifically, the partitioned winding drum 100 can be obtained by attaching the winding drum partition installation tool 300 to the winding body 210 of the winding drum 200 in a winding manner.
In the obtained partitioned winding drum 100, the winding body 210 of the winding drum 200 is partitioned into a provisional winding portion 110a and a final winding portion 110b.

Figure 1B shows the state in which a linear body 10 (in this embodiment, an optical fiber) is wound around the partitioned winding drum 100 as described above.

As shown in FIG. 1B, the linear body 10 is wound slightly around the temporary winding section 110a of the partitioned winding drum 100 so that one end of the linear body 10 is exposed on the surface. This exposes one end of the linear body 10 at the temporary winding section 110a, making it easier to access. In this embodiment, an optical connector 20 is attached to one end of the exposed linear body 10 (optical fiber). In FIG. 1B, one end of the linear body 10 and the optical connector 20 are protected by a thick protective hose 30.

On the other hand, in the main winding section 110b of the partitioned winding drum 100, most of the remaining linear body 10 is wound, and the other end of the linear body 10 is exposed on the surface of the main winding section 110b, making it easier to access. In this embodiment, an optical connector 20 is also attached to the exposed other end. Note that in the main winding section 110b, the other end of the linear body 10 and the optical connector 20 are also protected by a thick protective hose 30. Furthermore, the linear body 10 is not particularly limited as long as it is linear. Examples of the linear body 10 include optical fiber, electric wire, etc.

The components of the partitioned winding drum 100, the winding drum 200 and the winding drum partition installation device 300, are described below.

(Winding drum)
Fig. 2A shows a perspective view of the winding drum 200. As shown in Fig. 2A, the winding drum 200 has a winding body 210 and flange portions 220a and 220b.

The winding drum 210 is the part around which the linear body 10 and the winding drum partition installation device 300 are wound. The winding drum 210 is approximately columnar or cylindrical, and flanges 220a, 220b are attached to both ends. There are no particular limitations on the circumferential length of the winding drum 210 and the length in the width direction perpendicular to the circumferential direction, and these may be set appropriately depending on the thickness and length of the linear body 10 to be wound. There are no particular limitations on the material of the winding drum 210. In this embodiment, the material of the winding drum 210 is wood. The material of the winding drum 210 may also be resin or metal.

The flanges 220a and 220b are attached to both ends of the winding drum 210 and support the linear body 10 wound around the winding drum 210. The flanges 220a and 220b are disk-shaped, and the diameters of the flanges 220a and 220b may be set appropriately according to the thickness and length of the linear body 10 so that they can support the wound linear body 10. The material of the flanges 220a and 220b is not particularly limited. In this embodiment, the material of the flanges 220a and 220b is wood. The material of the flanges 220a and 220b may also be resin or metal.

(Winding drum partition installation tool)
2B is a perspective view seen from the front side of the winding drum partition installation tool 300. As shown in FIG. 2B, the winding drum partition installation tool 300 has a band-shaped body 310 and a plurality of partition sections 320.

The strip 310 is wound around the winding drum 210 of the winding drum 200, and a plurality of partitions 320 are installed on the winding drum 210. The length of the strip 310 may be appropriately set according to the thickness of the winding drum 210. The width of the strip 310 is not particularly limited as long as it is equal to or less than the width of the winding drum 210. In this embodiment, the width of the strip 310 is set so that it is approximately the same as the width of the provisionally wound portion 110a when the strip 310 is wound around the winding drum 210 so that the end of the strip 310 in the width direction contacts the flange portion 220a. That is, in this embodiment, the width of the strip 310 functions as a spacer for determining the width of the provisionally wound portion 110a. The width of the strip 310 may be set to be the width of the main winding portion 110b. In addition, the strip 310 may not function as a spacer and may be wound around any position of the winding drum 210. By winding the wire at any desired position on the winding drum 210, the width of the provisionally wound portion 110a and the width of the final winding portion 110b can be set as desired.
The material of the strip 310 is not particularly limited, but it is preferable that the material has a strength sufficient to allow the partitions 320 fixed to the strip 310 to stand on their own. In this embodiment, the strip 310 is a thin metal plate, more specifically, a hot-dip 55% aluminum-zinc alloy plated steel plate. The strip 310 may also be a resin plate. As a result, in this embodiment, the multiple partitions 320 fixed to the strip 310 stand on their own.

The partitions 320 are arranged along the longitudinal direction of the strip 310. The partitions 320 divide the winding body 210 of the winding drum 200 into a provisional winding section 110a and a main winding section 110b (see Figs. 1A and 1B). In this embodiment, there are four partitions 320, which are arranged parallel to one end (long side) of the short side of the strip 310. The shape of the partitions 320 is not particularly limited as long as it can function as a partition. In this embodiment, the shape of the partitions 320 is approximately rectangular (the winding body 210 side is arc-shaped) and plate-like. The size of the partitions 320 may be set appropriately according to the thickness, length, etc. of the linear body 10 to be wound around the main winding section 110b.

Figure 3A is a perspective view of the winding drum partition installation tool 300 from the back, showing how the partitions 320 are fixed to the band 310. In this embodiment, the partitions 320 are fixed to the band 310 using three screw members 31. In this way, when the partitions 320 are fixed to the band 310 in advance, it is possible to easily attach the partitions 320 to the winding drum 200. When the partitions 320 include wood, it is preferable that these screw members 31 have a length that allows them to be screwed deep into the partitions 320 (wood) in order to suppress warping of the wood.

As shown in FIG. 3B, it is preferable that the L-shaped metal fittings 32 are fixed to the multiple partitions 320 using screw members 31. The L-shaped metal fittings 32 are used to fix the winding drum partition installation tool 300 to the winding drum 210 of the winding drum 200. In this embodiment, the L-shaped metal fittings 32 are fixed to the winding drum 210 of the winding drum 200 using screw members 31 (see FIG. 1A). In this embodiment, the multiple through holes (see FIG. 3A) provided at both ends of the longitudinal direction of the strip 310 are also used to fix the winding drum partition installation tool 300 to the winding drum 210 using screw members 31.

By using the screw member 31 in this manner, the winding drum partition installation device 300 can be made detachable from the winding drum 210. The partition portion 320 can also be made detachable from the strip 310.
If the screw member 31 is made detachable, after use of the partitioned winding drum 100, the winding drum partition installation tool 300 can be removed, and the partition section 320 can be removed, allowing reuse and recycling. In addition, the normal winding drum 200 from which the winding drum partition installation tool 300 has been removed can be easily collected by a specialized collection company. In this embodiment, the screw member 31 is specifically a tapping screw.

In the above, an example of using the L-shaped bracket 32 and the screw member 31 has been described as an example of a detachable configuration, but the detachable configuration is not limited to this, and any known detachable configuration (such as a known fastener) can be used as appropriate.

As shown in FIG. 3B, it is preferable that the partitions 320 are arranged so as to protrude from one end of the strip 310 in the short direction of the strip 310. By arranging the partitions 320 in this manner, the linear body 10 being wound around the strip 310 is prevented from being damaged by the edge of the strip 310, which may be a metal plate or the like and may be sharp (see FIGS. 1A and B).

Also, as shown in FIG. 3C, in the winding drum partition installation device 300 (winding drum 100 with partition), a protective sheet 330 may be placed on the strip 310. The protective sheet 330 can prevent contact between the linear body 10 being wound around the winding drum 210 and the strip 310, and prevents the wound linear body 10 from being damaged by the strip 310, L-shaped metal fittings 32, etc.

The spacing between the multiple partitions 320 may be equal, but it is preferable that at least one of the spacings is wider than the others. As shown in FIG. 4, the gaps between the multiple partitions 320 serve as a passageway for the linear body 10 to enter from the provisionally wound section 110a to the fully wound section 110b. Therefore, if the spacing is wider, the linear body 10 can enter at a small angle of entry. This makes it possible to prevent an increase in damage caused by bending of the linear body 10 as it transitions from the provisionally wound section 110a to the fully wound section 110b.

(effect)
According to the winding drum partition installation tool 300 of this embodiment, a partition can be easily installed on the winding drum 200.

The winding drum partition installation tool of the present invention is useful for installing a partition on a winding drum.
