Description

This disclosure relates to a drum for cables and a method for packaging cables.

Cables such as optical fibers are wrapped around the body of a drum and packed for transport or storage. Wooden drums are mainly used. Wooden drums use many nails to connect multiple boards. Patent documents 1 to 3 describe examples of cable drums.

JP 2006-176171 A JP 2007-99406 A JP 2017-1721 A

The drum vibrates when the cable is transported and unwound, and the vibrations can cause nails to come loose. A fallen nail may damage the cable. Therefore, when a fallen nail is discovered, it is desirable to identify where the nail came from in order to determine the cause of the nail's fall. However, the nails used in drums are generally general-purpose nails, and it is difficult to identify which drum the nail came from and when it came out. As a means of identification, for example, using decorated nails makes it easier to identify the source, but this increases the cost compared to general-purpose nails. It may also take time to obtain decorated nails.

The present disclosure aims to provide a cable drum and a cable packaging method that makes it easy to identify which drum a nail has fallen out of.

The cable drum of the present disclosure has a body portion and a pair of flange portions provided at both ends of the body portion, the body portion has a plurality of first plate members forming the body portion and first nails for fixing the first plate members, and the first plate members and the first nails are colored with a first coloring agent.

This disclosure makes it easier to identify which drum the nail came out of.

The first nail in the body is colored with a first coloring agent. Therefore, if the first nail falls out, it is possible to tell that it has fallen out from this cable drum simply by checking the appearance of the fallen first nail. In other words, it is easy to identify which drum the first nail has fallen out from. In addition, coloring is easy because it is sufficient to color the first nail with the first coloring agent after it is hammered into the first plate material.

[2] In [1], the first coloring agent may contain a mold inhibitor or an insect repellent, or both. In this case, the mold resistance and insect resistance of the body can be improved.

[3] In [1] or [2], the flange portion may have a plurality of overlapping second plate materials and a second nail that fixes the plurality of second plate materials to each other, and the second plate materials and the second nails may be colored with a second coloring agent on the opposing surfaces of the pair of flange portions. In this case, it is easy to identify from which drum the second nail has come out.

[4] In [3], the second colorant may contain a mold inhibitor or an insect repellent, or both. In this case, the mold resistance and insect resistance of the flange can be improved.

[5] In [3] or [4], the color of the second colorant may be the same as the color of the first colorant. In this case, there is no need to change the color, making it easy to color.

[6] A cable drum according to another aspect of the present disclosure has a body and a pair of flanges provided at both ends of the body, the body has a plurality of first plates forming the body and a first nail for fixing the first plates, the flange has a plurality of second plates overlapping each other and a second nail for fixing the second plates to each other, the first plates and the first nails are colored with a first coloring agent, the second plates and the second nails are colored with a second coloring agent on the opposing surfaces of the pair of flanges, and the first coloring agent and the second coloring agent include a mold inhibitor or an insect repellent, or both.

The first nail in the body is colored with a first coloring agent, and the second nail in the flange is colored with a second coloring agent. Therefore, if the first nail or the second nail falls out, it is possible to know that it has fallen out from this cable drum simply by checking the appearance of the fallen first nail or the second nail. In other words, it is easy to identify which drum the first nail or the second nail has fallen out from. In addition, since the first plate material is also colored with the first coloring agent and the second plate material is also colored with the second coloring agent, the first nail can be colored with the first coloring agent after being driven into the first plate material, and the second nail can be colored with the second coloring agent after being driven into the second plate material. Therefore, coloring is easy. In addition, the mold resistance and insect resistance of the body and flange can be improved.

[7] A method for packaging cables according to another aspect of the present disclosure includes the steps of winding a cable around the body of the cable drum of any one of [1] to [6], and arranging a plurality of third plate members to cover the cable and fastening the plurality of third plate members to the pair of flanges with third nails.

If the first nail falls out after packaging, it is possible to tell that it fell out from this cable drum simply by checking the appearance of the fallen first nail. In other words, it is easy to identify which drum the first nail fell out from.

[8] In [7], the color of the first coloring agent may be changed depending on the timing of the process of winding the cable or the process of fixing the third plate material, or both of the process of winding the cable or the process of fixing the third plate material.

In this case, transfer of the first coloring agent to the cable can be prevented.

[10] In [7] to [9], after the step of fixing the third plate material, a step of coloring the third plate material and the third nail with a third coloring agent may be included. In this case, it is also possible to easily identify from which drum the third nail has come out.

[11] In [10], the color of the third coloring agent may be changed depending on the timing of the process of winding the cable and the process of fixing the third plate material. In this case, the traceability of the third nail can be further improved.

[Details of the embodiment of the present disclosure]
Hereinafter, the embodiments of the present disclosure will be described in detail, but the present embodiments are not limited thereto. In addition, in this specification and drawings, components having substantially the same functional configurations may be denoted by the same reference numerals to avoid redundant description.

An embodiment of the present disclosure relates to a drum for cables. Figure 1 is a perspective view showing a drum for cables according to an embodiment.

As shown in FIG. 1, the cable drum 1 according to this embodiment has a body portion 10, a flange portion 20, and a flange portion 30. The body portion 10 has a cylindrical shape, the flange portion 20 is provided at one end of the body portion 10, and the flange portion 30 is provided at the other end of the body portion 10. The flange portions 20 and 30 are an example of a pair of flange portions.

The body 10 includes a plurality of plate materials 11. The plate materials 11 have, for example, a rectangular parallelepiped shape with the axial direction of the body 10 as the longitudinal direction, the circumferential direction as the lateral direction, and the radial direction as the thickness direction. Between adjacent plate materials 11 in the circumferential direction of the body 10, the faces perpendicular to the lateral direction of the plate materials 11 face each other. The plate materials 11 are an example of a first plate material.

The flange 20 includes, for example, disk-shaped plate materials 21 and 22. The radii of the plate materials 21 and 22 are approximately the same and are larger than the radius of the body 10. The plate materials 21 and 22 are overlapped with each other, and the flange 20 includes a number of nails 23 that secure the plate materials 21 and 22 to each other. The plate material 21 is disposed closer to the body 10 than the plate material 22, and for example, the nails 23 are hammered from the plate material 21 side, with the tip exposed from the plate material 22 and bent so as to bite into the plate material 22. The flat surface of the head of the nail 23 is exposed on the surface of the plate material 21 facing the body 10. The plate materials 21 and 22 are an example of a second plate material, and the nail 23 is an example of a second nail.

Figure 2 is a perspective view showing the configuration of the plate material 21. As shown in Figure 2, for example, a disk-shaped convex portion 24 with an outer peripheral surface along the inner peripheral surface of the body portion 10 is provided at the radial center of the plate material 21. The body portion 10 includes a plurality of nails 12 that fix the plate material 11 to the convex portion 24. The flange portion 20 is fixed to the body portion 10 by fixing the plate material 11 to the convex portion 24 with the nails 12. Although not shown, in order to further strengthen the connection between the flange portion 20 and the body portion 10, a nail that penetrates the plates 22 and 21 from the plate material 22 side and enters the inside of the plate material 11 from a surface perpendicular to the longitudinal direction of the plate material 11 may be further provided. The nail 12 is an example of a first nail.

The flange 30 includes, for example, disk-shaped plate materials 31 and 32. The radii of the plate materials 31 and 32 are approximately the same and are larger than the radius of the body 10. The plate materials 31 and 32 are overlapped with each other, and the flange 30 includes a number of nails 33 that secure the plate materials 31 and 32 to each other. The plate material 31 is disposed closer to the body 10 than the plate material 32, and for example, the nail 33 is hammered from the plate material 31 side, with the tip exposed from the plate material 32 and bent so as to bite into the plate material 32. The flat surface of the head of the nail 33 is exposed on the surface of the plate material 31 facing the body 10. The plate materials 31 and 32 are an example of a second plate material, and the nail 23 is an example of a second nail.

At the radial center of the plate 31, a disk-shaped protrusion (not shown) is provided, for example, with an outer peripheral surface along the inner peripheral surface of the body 10, similar to the protrusion 24. The body 10 includes a plurality of nails 12 that fix the plate 11 to this protrusion. The flange 30 is fixed to the body 10 by fixing the plate 11 to the protrusion with the nails 12. Although not shown, in order to further strengthen the connection between the flange 30 and the body 10, a nail may be further provided that penetrates the plates 32 and 31 from the plate 32 side and enters the inside of the plate 11 from a surface perpendicular to the longitudinal direction of the plate 11. The nail 12 is an example of a first nail.

In this embodiment, the plate material 11 and the nails 12 of the body 10 are colored with the coloring agent 2. The plate material 21 and the nails 23 may be colored with the coloring agent 2 on the surface of the flange 20 facing the flange 30, and the plate material 31 and the nails 33 may be colored with the coloring agent 2 on the surface of the flange 30 facing the flange 20. As the coloring agent 2, an oil-based paint or the like is used. The coloring agent 2 that colors the plate material 11 and the nails 12 is an example of a first coloring agent. The coloring agent 2 that colors the plate material 21 and the nails 23 and the coloring agent 2 that colors the plate material 31 and the nails 33 are an example of a second coloring agent.

In the cable drum 1 according to this embodiment, the nail 12 on the body 10 is colored with a coloring agent 2. Therefore, even if the nail 12 itself is a general-purpose nail, if the nail 12 falls out of the cable drum 1, it is possible to tell that the nail 12 has fallen out of the cable drum 1 simply by checking the appearance of the nail 12. In other words, it is possible to easily identify that the nail 12 has fallen out of the cable drum 1.

Similarly, even if the nails 23 of the flanges 20 and 30 are colored with the coloring agent 2, or even if the nails 23 themselves are general-purpose nails, if the nails 23 fall out of the cable drum 1, it is possible to tell that they have fallen out of the cable drum 1 simply by checking the appearance of the nails 23. In other words, it is easy to identify that the nails 23 have fallen out of the cable drum 1.

Next, a method for manufacturing the cable drum 1 will be described. Figures 3 and 4 are perspective views showing a method for manufacturing the cable drum 1 according to an embodiment.

First, as shown in FIG. 3, the body 10 and the flange 20 are connected, and the body 10 and the flange 30 are connected. At this time, multiple nails 12 are hammered into the convex portion 24 of the plate material 21 from above the plate material 11, and multiple nails 12 are hammered into the convex portion (not shown) of the plate material 31 from above the plate material 11.

Next, as shown in FIG. 4, the plate material 11 and nails 12 of the body 10 are colored with coloring agent 2. In addition, the plate material 21 and nails 23 on the surface of the flange 20 facing the flange 30 may be colored with coloring agent 2, and the plate material 31 and nails 33 on the surface of the flange 30 facing the flange 20 may be colored with coloring agent 2.

In this way, the cable drum 1 can be manufactured.

In this manufacturing method, the plate material 11 and nails 12 of the body 10 are colored with coloring agent 2, so a wide area can be colored in a single color. This makes the coloring process easy. Similarly, if the plate material 21 and nails 23 are colored with coloring agent 2 and the plate material 31 and nails 33 are colored with coloring agent 2, an even wider area can be colored in a single color. This makes the coloring process easy.

In order to simplify the manufacturing process, it is preferable that the plate material 11 and the nails 12, the plate material 21 and the nails 23, and the plate material 31 and the nails 33 are colored with the same coloring agent 2. On the other hand, in order to easily distinguish the nails 12 that have fallen out of the body portion 10 from the nails 23 that have fallen out of the flange portion 20 or 30, the coloring agent (first coloring agent) used to color the plate material 21 and the nails 23 and the plate material 31 and the nails 33 may be different in color from the coloring agent (second coloring agent) used to color the plate material 21 and the nails 23 and the plate material 31 and the nails 33.

The color of the coloring agent 2 may also be different depending on the time of manufacture of the cable drum 1. For example, the color may be different for each year of manufacture, each month of manufacture, or each date of manufacture. By varying the color of the coloring agent 2 depending on the time of manufacture, the traceability of the nails 12 and 23 can be further improved.

The coloring agent 2 preferably contains a mold inhibitor or an insect repellent, and more preferably contains both a mold inhibitor and an insect repellent. This is to prevent deterioration of the wooden cable drum 1 due to mold or insects. The mold inhibitor or insect repellent may be applied separately from the coloring agent 2, but by including it in the coloring agent 2, the number of application steps can be reduced.

The flanges 20 and 30 may each be made of a single plate material. In this case, the nails 23 and 33 are not required.

Next, a method for packaging cables using the cable drum 1 will be described. Figures 5 to 8 are perspective views showing a method for packaging cables using a cable drum.

When packaging the cable, first, as shown in FIG. 5, the cable drum 1 according to the above embodiment is prepared, and the body 10 is covered with a sheet 3. The sheet 3 may be made of an inexpensive material such as wax-coated paper, a vinyl sheet, a plastic sheet, or an air cushion.

Next, as shown in FIG. 6, the cable 4 is wrapped around the body 10 from above the sheet 3. The cable 4 is, for example, an optical fiber cable.

Next, as shown in FIG. 7, multiple plate materials 41 are fixed to the outer periphery of the cable drum 1. The plate materials 41 have a rectangular parallelepiped shape, and are arranged so as to cover the cable 4, with, for example, the axial direction of the body 10 being the longitudinal direction, the circumferential direction being the lateral direction, and the radial direction being the thickness direction. The plate materials 41 can be fixed to the flange portions 20, 30 by driving nails 42 through the plate materials 41 and penetrating the flange portions 20, 30 from the outer periphery of the flange portions 20, 30. The plate materials 41 are an example of a third plate material, and the nails 42 are an example of a third nail.

Next, as shown in FIG. 8, the board 41 and nails 42 are colored with coloring agent 5. As the coloring agent 5, an oil-based paint or the like is used. The coloring agent 5 preferably contains a mold inhibitor or an insect repellent, and more preferably contains both a mold inhibitor and an insect repellent. This is to prevent deterioration of the wooden board 41 due to mold or insects. The mold inhibitor or insect repellent may be applied separately from the coloring agent 5, but by including it in the coloring agent 5, the number of application steps can be reduced. The coloring agent 5 is an example of a third coloring agent.

Then, as shown in FIG. 8, the multiple plate materials 41 are wrapped around the wire 43, and the wire 43 is fixed to the plate materials 41 with the fasteners 44.

In this manner, the cable 4 can be packaged.

In this cable packaging method, because a cable drum 1 is used, it is possible to identify that a nail 12 colored with a coloring agent 2 has fallen out of the cable drum 1. In addition, the nail 42 is colored with a coloring agent 5. Therefore, even if the nail 42 itself is a general-purpose nail, if the nail 42 falls out of the plate material 41, it is possible to know that it has fallen out of the plate material 41 simply by checking the appearance of the nail 42. In other words, it is possible to easily identify which drum the nail 42 has fallen out of.

The color of the coloring agent 5 may be changed depending on the time when the cable 4 was packed. For example, the color may be changed for each year when the cable was packed, for each month when the cable was packed, or for each day when the cable was packed. By changing the color of the coloring agent 5 depending on the time when the cable was packed, the traceability of the nail 42 can be further improved. In addition, the color of the coloring agent 2 may be changed in advance depending on the time when the cable 4 was packed.

In this embodiment, the body 10 is covered with the sheet 3 before the cable 4 is wrapped around the body 10. This prevents the coloring agent 2 from being transferred to the cable 4. It also makes it difficult for the nail 12 to come out of the board 11.

The cable drum 1 can be reused. However, if the coloring of the nails 12 and 23 starts to peel off, it is recommended that they be recolored with the coloring agent 2.

Although the embodiments have been described in detail above, the present invention is not limited to the specific embodiments, and various modifications and variations are possible within the scope of the claims.
