The specific embodiment
Below, with reference to accompanying drawing, the example of embodiment involved in the present invention is described.
As shown in Figure 1, optical fiber 10 for example uses resin-coating to form in the periphery of the glass fibre being made up of fibre core and covering, and its external diameter is for example 250 μ m.These optical fiber 10 boundlings become optical cable and for such as light communication etc.
For the bobbin 11 of this optical fiber 10 of reeling, for example formed by synthetic resin such as plastics, there is main part 11a cylindraceous and the discoideus 11b of pair of flanges portion that is arranged on this main part 11a two ends.
In the time that optical fiber 10 is wound on bobbin 11, optical fiber 10 must be wound on the main part 11a of bobbin 11 equably.Therefore,, as bobbin 11, it moves back and forth with the speed that moves back and forth of regulation by not shown moving back and forth with electrical motor on one side in the axial direction of bobbin 11, on one side by wound thereon optical fiber 10.In addition, the method for winding of optical fiber 10 is not limited to this bobbin and moves back and forth mode.For example, also can adopt following roller to move back and forth mode, that is, make bobbin 11 become stationary state, the guide reel that optical fiber 10 before reeling is guided is moved back and forth in the axial direction of bobbin 11, thereby optical fiber 10 is wound on equably on the main part 11a of bobbin 11.
In the present embodiment, the winding tension of optical fiber 10 is made as to T(N), reciprocal spacing is made as to P(mm) time, to make T/P
2be more than or equal to 0.5N/mm
2and be less than or equal to 6.3N/mm
2mode, optical fiber 10 is wound on bobbin 11.
Here, reciprocal spacing P represent the optical fiber 10 to reel on bobbin 11 bobbin 11 1 week time or the amount of movement of guide reel.In the present embodiment, back and forth spacing P is for example 0.4 to 0.7mm.
Compared with reciprocal spacing P, think that winding tension T unclamps for coiling and to transmit the impact of loss larger.,, compared with the variable quantity of winding tension T, back and forth the impact of the variable quantity of spacing P is difficult for embodying numerically.Therefore, in the present embodiment, make the i.e. " T/P of square value obtaining of winding tension T divided by reciprocal spacing P by employing
2", thereby make winding tension T and back and forth balanced between spacing P.
As shown in Figure 2, the related packing chest 20 of present embodiment has the casing 21 as its essential structure.This casing 21 has the upper surface portion 24 that forms the bottom surface sections 22 of bottom surface, the side surface part 23 that forms side and formation upper surface.
As shown in Figure 3, be provided with separator of battery plates 25 in the inside of the casing 21 of packing chest 20, form multiple receiving space S in the inside of casing 21 by this separator of battery plates 25.In these receiving spaces S, contain the bobbin 11 shown in Fig. 1.
As casing 21, use for example long 800mm of being, the wide shape that be 640mm, height and be 320mm, for example can accommodate 8 bobbins 11 that are wound with optical fiber 10.
As shown in Figure 4, in the bottom surface sections 22 of casing 21, for example, dispose the padded coaming 27 that polylith (being 3 herein) is formed by strengthening carboard.Bobbin 11 is housed in to the top of above-mentioned polylith padded coaming 27.
And, to be housed in the state in the receiving space S of packing chest 20 after optical fiber 10 is wound on bobbin 11, transport and keeping.
Conventionally, optical fiber 10 is housed in packing chest 20 and dispatches from the factory to be wound on state on bobbin 11, uses the transportations such as truck, ship or aircraft.
When being wound in optical fiber 10 on bobbin 11 and transporting, if winding tension T when optical fiber 10 is wound on bobbin 11 is lower, there is optical fiber 10 and reel and unclamp in the vibration while transportation due to optical fiber 10 sometimes etc.Be the major cause optical fiber 10 is broken in the time that optical cable is manufactured in bobbin 11 pull-outs because the coiling of this optical fiber 10 unclamps, therefore, the operation of the optical fiber 10 of need to again reeling, causes workability variation.
On the other hand, if improve the winding tension T of optical fiber 10 in order to prevent optical fiber 10 coilings from unclamping, can make to transmit loss increase because powerful contact between optical fiber 10 makes the glass fibre of optical fiber 10 be subject to side pressure.
In addition, if unclamp and reciprocal spacing P is exceedingly narrowed in order to prevent that optical fiber 10 from reeling, adjacent optical fiber 10 contacts, and the impact of the side pressure causing due to the contact between optical fiber 10, increases the transmission loss of optical fiber 10.On the other hand, if back and forth spacing P increases, can between adjacent optical fiber 10, form excessive gap, therefore, optical fiber 10 possibility of unclamping of reeling occur in the time that bobbin 11 transports and become greatly.
On the other hand, the optical fiber 10 related according to present embodiment, the winding tension in the time that optical fiber 10 is wound on bobbin 11 is made as T(N), reciprocal spacing is made as to P(mm) time, set and make T/P
2be more than or equal to 0.5N/mm
2and be less than or equal to 6.3N/mm
2.,, by the winding tension T of optical fiber 10 with in back and forth spacing P is adjusted into suitable value, optical fiber 10 is wound on bobbin 11.Thus, can suppress as far as possible the increase of the transmission loss of optical fiber 10, and, time can be transported, prevent that optical fiber 10 coilings from unclamping in the bobbin 11 that is wound with optical fiber 10 is housed in to packing chest 20.
And, according to this optical fiber 10, can suppress with transportation after the coiling of optical fiber 10 unclamp the broken string of optical fiber 10 together, and, do not need to re-start the coiling of optical fiber 10, can improve workability.
In addition, in the present embodiment, because the bottom surface sections 22 at packing chest 20 disposes polylith padded coaming 27, bobbin 11 is housed in to the top of these padded coamings 27 and transports, therefore, can suppress to be in transit applied to the impact on optical fiber 10, prevent that reliably optical fiber 10 coilings from unclamping.
