Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an apparatus for manufacturing a cable by twisting a plurality of core wires.

This type of conventional device, which is called a winding rotary type, has a plurality of wire feeders 1, 1, 1..., a wire gatherer 2, as shown in FIG. 1 (plan view).
It is mainly composed of a rotary traction machine 3, a rotary winding machine 4, etc., and in some cases, a tape winding machine 5 is arranged between the core wire gathering machine 2 and the rotary traction machine 3. There are some things.

When manufacturing cables using the above-mentioned apparatus, the core wires 6, 6, 6, etc. unwound from the core wire feeders 1, 1, 1, etc. are passed through the core wire assembly machine 2, and collected. The collected assembly is picked up by a rotary traction machine 3 equipped with an endless track rotating body 8 and twisted into a cable 7, and then the cable 7 is passed through the entrance 12 of the winding machine 4 into the inside thereof. The cable 7 is introduced through the traverser 10.
is wound onto a winding drum 9, and at this time, the rotary traction machine 3 and the winding machine 4 are arranged to rotate synchronously around a horizontal axis.

In FIG. 1, 9' indicates the flange of the winding drum 9, and 11 indicates the wound cable after winding.

In the case of the conventional example in which the cable is manufactured in this way and is wound onto the winding drum 9, each time the winding machine 4 rotates once, the winding drum 9
is now vertical twice, and when it is vertical, the weight of the wrapped cable 11 is applied to the flange 9' of the drum 9.

For example, when a 6KV triplex type CV cable (3 cores, cross-sectional area 325mm ² , 150m length) is wound onto the winding drum 9, its weight will be 1.8t, compared to a normal wooden drum (flange diameter 2.3m). In this case, the flange portion 9' is particularly damaged.

Therefore, in the case of the above-mentioned conventional example, a special winding drum 9 with sufficient strength is made, and after the cable 7 is once wound around the winding drum 9, the wound cable 1 is
1 is wound back onto a winding drum for shipping (made of wood, etc.), but this requires extra work for rewinding.

Furthermore, in order to reduce the labor involved in rewinding, a large winding drum 9 is made, a large amount of cable 7 is wound around it, and a means for rewinding and distributing the cables 7 from the drum 9 to each winding drum for shipping is also provided. However, increasing the size of the winding drum 9 in this way increases the size of the entire winding machine 4, which in turn increases the overall length of the cable production line.
Since the rotational speed of the machine 4 is restricted, cable manufacturing efficiency is reduced.

Moreover, the rewinding process still remains, so
Even from the perspective of process reduction, problems remain.

In view of the above-mentioned problems, the present invention provides a core wire supply system,
In this type of cable manufacturing equipment, which consists of a core wire twisting system and a cable winding system, these systems are skillfully arranged, and each system is smoothly connected via a direction changing mechanism to create a winding system.

In the cable twisting system, each of the cables 6a, 6a, 6a, etc. sent as described above is transferred to a cable assembly machine 2a.
These core wires 6a, 6a, 6a... are collected by passing through the batten ₂₁ and dies ₂₂ , ₂₃ , and then twisted while being pulled by the endless track rotating body 8a of the cable pulling machine 3a.

Furthermore, in the above-mentioned winding machine 4a, the winding drum 9a having the horizontal rotation axis _V4 is operated by its drive unit 25 in order to compensate for the change in cable tension caused by the increase in the diameter of the wound cable 11a. The speed of the traverser 10a is controlled by a control system (not shown), which ensures constant cable tension.
In order to wind the cable 7a around the winding drum 9a in an aligned manner, the speed of the driving machine 26 is controlled by a control system (not shown) so that the operating state is in harmony with the winding drum 9a.

Next, another embodiment of the present invention will be explained with reference to FIG.

In this embodiment, when a long cable such as a submarine cable is twisted and manufactured, the winding system is adapted to accommodate this.

In the winding system here, a plurality of wheels 27, 27... are attached to the lower surface of the horizontal rotating bed 22, and each wheel 27, 27... is attached to the annular rail 28 below the floor surface GL.
It is designed to run on top.

The rotary base plate 22 in the above example has the same vertical rotation axis V ₃ and is rotated by the drive machine 29, but the load applied to the base plate 22 is caused by the wheels 27, 2.
7... and the annular rail 28, the structure can withstand a large load.

Furthermore, the winding machine 4a installed on the rotary platform 22 is equipped with a winding basket 9b instead of the winding drum 9a.
On the lower surface of is a lifting mechanism 29, 29, etc., such as a hydraulic type.
Inner wheels 31, 31 with motor 30 are connected via...
A plurality of wheels are attached in an annular arrangement, and outer wheels 32, 32 for straight-line running are attached to the outside of these inner wheels 31, 31....

An annular inner rail 33 and outer straight rails 34, 34 are provided on the rotating platform 22 in FIG.
31 is mounted on the annular inner rail 33, so that it is rotatably supported on the rotary base 22, and in this state, the outer wheels 32, 32 can be mounted on the outer straight rails 34, 34.

Therefore, the winding basket 9b described above has inner wheels 31, which are self-propelled by motors 30, 30...
31... and the annular inner rail 33, and the axis of rotation _V5 at this time is in the vertical direction.

In addition, the elevating mechanism 29 of the inner wheels 31, 31...
29... is contracted in the vertical direction, the winding basket 9b is lowered and the outer wheels 32, 32 are placed on the outer straight rails 34, 34, and the above-mentioned elevating mechanisms 29, 29... are further contracted. Then, the inner wheels 31, 31 move upward toward the lower surface of the take-up basket 9b and come to be separated from the inner annular rail 33.

In this state, the winding basket 9b is rotated by the wheels 3.
2, 32 and the above-mentioned rails 34, 34, so that the winding basket 9b can be taken out in the linear direction along the rails 34, 34.

The traverser 10a shown in FIG. 3 is generally the same as that shown in FIG. .

In the cable winding system in this embodiment, a winding machine 4a is rotated by a rotary table 22 with _V3 as the rotation axis, and a winding basket 9b of the winding machine 4a is
Rotates around _V5 as the rotation axis.

When the cable 7a from the core wire twisting system is sent to such a winding system, the cable 7a is held by the traverser 10a via the guide mechanism 20 located at the entrance section 12a of the winding machine 4a. Due to the cable shift by the traverser 10a and the winding rotation of the winding basket 9b, the cable is wound into the basket 9b in a spiral shape and in a layered manner.

At this time, the rotating platform 22 is operated by the cable traction machine 3 in order to prevent twisting of the cable 7a as described above.
The take-up basket 9b, which rotates synchronously with the cable 7a at the same speed as the cable 7a, is attached to this rotating base 2.
It will rotate faster than 2.

As explained above, the present invention provides a cable manufacturing apparatus in which a core supply system, a cable winding system, and a cable twisting system between the two systems are arranged on a series of production lines. A cable feeding machine and a winding machine for the cable winding system are rotatably arranged on the floor at the same height, each having a vertical axis of rotation, and a cable winding machine for the cable winding system. A cable traction machine having a horizontal axis of rotation is rotatably arranged at a higher position than the above-mentioned cable supplying machine and winding machine, and is located between the cable supply system and the cable twisting system. In this case, a direction changing mechanism is interposed to guide the cable to the cable twisting system, and a direction change mechanism is provided between the cable twisting system and the cable winding system to guide the cable from the cable twisting system to the cable winding system. It is characterized in that a direction change mechanism is interposed for guiding the winding system to the winding system.

Therefore, in the case of the device of the present invention, the wire twisting system can be of the horizontal type, which is convenient for the twisting work, and the wire supply system and the cable winding system, especially the cable winding system, can be of the vertical type. This eliminates the lack of strength of the cable winding system without taking any special measures, and allows the lightweight drum for shipping to be used as is when producing a wrapped cable having a unit weight.

As a result, the rewinding step of winding the cable once onto a large winding drum and then distributing it onto a lightweight drum for shipping can be omitted.

Of course, the direction changing mechanism interposed between each system ensures smooth running of the core wire during supply and the cable during winding, making the overall work from core wire supply to cable winding stable and stable. It can be done rationally.

Moreover, since the core wire supply machine for the core wire supply system and the winder for the cable winding system are arranged on the floor at the same height, it is not only easy to handle various drums, but also The wire feeder and cable winder rotate around the vertical axis of rotation (revolutionary motion)
Therefore, untwisting can be performed in both the cable twisting system and the cable winding system, and this point is also highly useful.

Furthermore, instead of arranging the core supply system, cable twisting system, and cable winding system in a straight line, the core supply system and cable winding system are arranged on the floor, and the cable twisting system is arranged on the floor. Because it is placed above the system, less floor space is consumed and the production line can be shortened.
