Abstract

PURPOSE:To increase the amount of wind-up, by winding up the wind-up section of a long length material alternately onto a plurality of cable reels while the reels are normally and reversely rotated in synchronism with the fastening and loosening of wind- up section of the long length materials which are caused by normally and reversely rotating a casing on a core shaft. CONSTITUTION:When the core shaft 6 of a rotary member is rotated in the direction A so that the wind-up section 14 of a long length material 1 is fastened, and simultaneously, when cable reels R1 through Rn are rotated in the same direction, the wind-up section 15 of the long length material 1 is at first wound up. When the fastening of the wind-up section 14 comes to its limit condition, the reels R1 becomes full. When the core shaft 6 is rotated in the reverse direction so that the fastened wind-up section 14 is loosened, and simulteneously, when the reels R1 through Rn are rotated in the same direction, the section of the wind-up section 15 which is not yet wound up is wound up on the reel R2 while it is fitted into locking grooves in the side plates 11a of the reel, and when the loosening of the wind-up section 14 comes to its limit condition, the reel R2 becomes full. Subsequently, if the rotation is repeated in the order of reverse, normal, reverse..., the wind-up section 15 of the long length material 1 is wound up onto the reels R1 through Rn, thereby the amount of wind-up may be increased.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a winding method for winding optical cables (including optical cords), optical composite cables, and various other long objects.

(Prior art) Moving equipment such as stacker cranes and reclaimers,
Recently, noiseless and lightweight optical fiber-based optical cables and optical composite cables have begun to be used for communication and power supply with fixed devices that control and monitor the operating status of these devices.

As is known, in this type of elongated body equipped with optical fibers,
Optical fibers cannot be connected between rotating bodies and non-rotating bodies through sling rings unlike metal conductors, and therefore, Japanese Patent Application Laid-open Nos. 58-181264 and 57-148704
The inventions disclosed in various publications such as No.

In one of the inventions, six shafts and a casing around the outer periphery are provided so as to be relatively rotatable, and an optical cable is loaded in a spiral state between these six shafts and the casing. The cable reel can rotate within the range from the tightened state to the unwound state, and is therefore a rotating body.

Slip ring-less communication across non-rotating objects can be performed while unwinding or winding the cable.

The other invention is based on the same principle as the above-mentioned invention, and in addition, it is based on the cross-sectional shape of the optical cable.
We are trying to further increase the amount of rotation.

(Problems to be solved by the invention) In the case of these prior arts, reasonable results have been achieved within the scope of the invention, but for example, the amount of winding (= unwinding amount) of optical cable used in geothermal development etc. is 1000. ~6000m
However, there is a need for a long body winding technique that satisfies this requirement.

(Means for Solving the Problems) The method of the present invention was developed to solve the problem of the insufficient winding amount of long bodies in the conventional example, and its feature is that the six shafts and the casing on the outer periphery of the six shafts and a plurality of rotatable cable reels are arranged adjacent to the casing, and a part of the elongated body is loaded in a spiral state between the outer periphery of the six axes and the inner periphery of the casing. Then, one end and the other end of the spiral part are fixed to these six shafts and the casing, and the winding part side of the elongated body is wound up by each cable reel, and arranged on the cable reel side so that it can be unwound freely. ''When one of the two central shafts and the casing is a rotating body and the other is a non-rotating body, the rotating body is reversely rotated at IF, thereby winding and unwinding the spiral part of the elongated body. Each cable reel is rotated forward and backward in synchronization with the rotating body, and the winding portion of the elongated body is alternately wound and unwound by the respective cable reels.

(Function) In the method of the present invention, the rotating body and the non-rotating body can be rotated relative to each other within the range from the rolled up state to the unwound state of the distributing part, and in this case, the rotating body rotates in synchronization with the rotating body. By distributing the take-up side of the elongated body to each cable reel and winding it in an alternate reverse winding manner, it is theoretically possible to wind up an infinitely long elongated body, and it is possible to wind the elongated body to each cable reel of 1000 to 8000 m as specifically requested.
A certain amount of winding can be easily achieved.

(Example) Hereinafter, specific examples of the method of the present invention will be described with reference to the drawings.

FIG. 1 shows a tape-type optical cable as a long body 1 that is wound up and unwound according to the method of the present invention.

This elongated body 1, ie, the optical cable, includes a plurality of optical fibers 2 and a plurality of elastic members 3 which also serve as tensile strength members.
4 and a coating layer 5 that covers the optical fiber 2 and the elastic member 3.4.

Optical fiber 2 has a core diameter of 50 ILIm and a cladding diameter +
25, the core wire diameter (covering diameter) is 0.9+u+, and the elastic member 3.4 is made of FRP,
The diameter of one side 3 is 0.9 mm, and the diameter of the other side 4 is 2+am.

The coating layer 5 is made of, for example, polyethylene with a thickness of 50 μl and 25 μm,
m-thick polyester.

Therefore, the thickness of the optical cable is X
The width is approximately 1.5+sm x 45mm.

Note that as the elastic members 3 and 4, a metal having conductivity and elasticity, such as phosphor bronze, may be used.

As the elongated body 1, the one shown in Japanese Patent Laid-Open No. 57-148704 is also preferable.

In FIGS. 2 and 3 showing each means for winding up the elongated body l, 6 is a 6 that is pivotally supported by bearing stands 7a and 7b.
The shaft 8 is a casing attached to the outer periphery of the shaft 6 via a bearing 9.

R1-Rn are a plurality of cable reels fitted in parallel to each other on the outer periphery of the six shafts 6, and side plates 11 attached to the winding drums 10 of these cable reels R1-Rn
Locking grooves 12a and 12b are formed in a and Ilb as shown in FIGS. 4(a) and 4(b).

One of the six shafts 6 and the casing 8 is a rotating body and the other is a non-rotating body, but in the case of FIG. 2 where the six shaft 6 is a rotating body, the six shafts are A driving source for rotation is connected to 6, and each cable reel R
1 to Rn are fixed to six shafts 6, and a casing 8 as a non-rotating body is fixed to, for example, a bearing stand 7a via a fixture 13.

In the case of FIG. 3 in which the casing 8 is a rotating body, the casing 8 is of course held so as to be rotatable around the six shafts 6, but in this case, the six shafts 6 and each cable reel R1 to A bearing (same as the bearing 9) is interposed between the casing 8 and each cable reel R1 to Rn, and the casing 8 and each cable reel R1 to Rn are connected to each other so as to rotate simultaneously, and a driving source for rotation is connected to the casing 8 or the cable reel Rn. be done.

As described below, a part of the long body l made of the optical cable becomes a spiral part 14, and the other part becomes a winding part 15.
becomes.

In other words, part of the elongated body l is made into a spiral state and has 6 axes 6
It is loaded between the outer circumference and the inner circumference of the casing 8, and one end and the other end of the spiral portion 14 are connected to the six shafts 6 and the casing 8.
On the other hand, the winding portion 15 side of the elongated body l is wound up by each cable reel R1 to Rn, and arranged on the side of these cable reels R1 to Rn so that it can be unwound freely.

In the case of FIG. 2 in which the six shafts 6 are rotating bodies, the winding start end lB side of the spiral portion 14 passes through the six shafts 6 and reaches the winding start end lB of the winding section 15.
The winding end 17 of the spiral portion 14 is interconnected with the B side.
The side is pulled out of the casing 8.

In the case of FIG. 3 in which the casing 8 is a rotating body, the winding start end 16 side of the spiral portion 14 is pulled out to a predetermined location through the core axis θ, and the winding end 17 side of the spiral portion 14 and the winding end 17 side of the winding portion 15 are pulled out through the core axis θ. The winding start end IB side is wire-connected to each other.

Next, the case of winding up and unwinding the winding portion 15 of the elongated body l will be explained.

In FIG. 2, the six shafts 6, which are rotating bodies in this illustrated example, are rotated in the positive direction (in the direction of the arrow) so that the spiral portion 14 of the elongated body l is tightly wound, and together with this, each cable reel R1 ~Rn in the same direction, the winding part 15 of the elongated body l is first wound up by the cable reel R1, and when the winding state of the spiral part 14 reaches the limit, the cable reel R1 is in a full state.

Next, in order to unwind the tightly wound spiral portion 14,
When the six shafts 6 are rotated in the opposite direction (direction of arrow B) and the cable reels R1 to Rn are also rotated in the same direction, the unwound portion of the winding portion 15 on the elongated body 1 is rotated as shown in FIG. ) is wound up by the cable reel R2 while being fitted into the locking groove 12a of the side plate 11a, and when the unwinding state of the spiral portion 14 reaches its limit, the cable reel R2 becomes fully wound.

Once again, when the six shafts 6 are rotated in the positive direction and the cable reels R1 to Rn are rotated in the same direction so that the spiral portion 14 of the elongated body 1 is tightly wound, -I- The unrolled portion of part 15 is the side plate 11b shown in FIG. 4(b).
If the cable reel R fits into the locking groove 12b of
3, and when the unwinding state of the spiral portion 14 reaches its limit, the cable reel R3 becomes fully wound.

Thereafter, the above-mentioned rotation may be repeated in the order of reverse, forward, reverse, etc., and thereby the winding portion 15 of the elongated body 1 is wound up to the cable reel Rn.

When unwinding the winding part 15 of the elongated body 1 from each cable reel R1 to Rn, it is sufficient to rotate the six shafts 6 and each cable reel R1 to Rn alternately in forward and reverse directions in the reverse order to that described above. The winding section 15 can be undone.

In the case of FIG. 3 in which the casing 8 is a rotating body, the casing 8 and each cable reel R1 to Rn may be rotated in forward and reverse directions or alternately in opposite directions with respect to the six shafts 6 in a fixed state. The winding section 15 of the elongated body 1 can wind up and unwind.

In item 1-1, for example, if the winding capacity per cable reel is 20 h+m and the number of cable reels is 5, a long body l as long as 1100 Offi can be wound.

In addition, when the elongated body 1 is a composite optical cable having a core wire made of a metal conductor in addition to the optical fiber, the core wire made of the metal conductor is also wire-connected or pulled out to a predetermined location in the same manner as described above.

However, in the case of metal conductors, connections can also be made via slip rings.

For example, the winding portion 15 of the elongated body 1 may have a circular cross section.

In the case of FIG. 2, a predetermined number of one-way clutches are connected to the center Ikl+
They may be interposed between e and each of the cable reels R1 to Rn in a counter-rotating manner.

The crossing portion of the elongated body 1 between each cable reel R1-Rn is connected as shown in FIGS. 4(a) and 4(b).
■In addition to being fitted into the cable reels 12a and 12b to hold them, the side plates 11a of these cable reels R1 to Rn,
The side plate 11a,
A bushing-type locking mechanism, for example, a known part that can be locked on by the first bushing and locked off by the second bushing, is provided on the four parts provided on the outer periphery of 11b, thereby holding the above-mentioned crossing part. good.

When fitting the crossing portion of the elongated body l into the locking grooves 12a and 12b of the side plates 11a and llb, the crossing portion may be guided by, for example, a guide arm that shifts along the six axes 6. In such a case, the crossing portions will surely fit into the locking grooves 12a, 12b.

In addition, the method of the present invention can be applied to winding and unwinding long bodies other than the cables.

(Effects of the Invention) As explained above, when the method of the present invention is used, a predetermined rotating body is rotated in forward and reverse directions, and when the spiral portion of the elongated body is wound and unwound, each coil is synchronously rotated with the rotating body. Instead of rotating the cable reel in the forward and reverse directions, the winding portion of the elongated object is wound and unwound by alternating reverse winding on each cable reel, so the amount of winding of the elongated object is dramatically improved. .
