いる。In general, in the stranded wires that make up communication cables, the unit of stranded wires made by twisting each of the four strands in the same direction while giving a twist back is called a quad stranded wire or simply a katsudo. It is well known that the purpose of imparting twists to twisted wires for communication cables is primarily to improve the electrical characteristics of the cable.

して広く使用されているものである。A set of five quad stranded wires twisted in the same direction is called a 5-quad set strand, or simply 5-quad, and is widely used as a representative stranded wire unit that makes up a communication cable. It is something.

して新たな効果が期待され得るものである。The pre-process of producing the 5-cut stranded wire, which involves twisting in the same direction, is replaced with an alternating twisting process that provides alternating reversal twists with relatively short cycles, and then the post-process The process of collective twisting, which imparts twists in the same direction, is replaced by alternate twisting, which similarly imparts alternating reverse twists with a relatively short cycle, i.e., in the latter case, the so-called slackening process can be said to be Alternating 5
It should also be referred to as a quad-sag group stranded wire, in which each strand is not untwisted, and the stranded wire as a whole has the same electrical characteristics as if it were untwisted. Moreover, at any point along the entire length of the stranded wire, without cutting the cable, by releasing the restraint winding, all the strands can be easily and orderly taken out with approximately equal length. New effects can be expected as a completely newly developed twisted wire unit for communication cables, which retains slack (sag) and makes cable connection work extremely convenient.

俟たない。The present invention is capable of producing the seed stranded wires including the alternating 5-cut slacked collective stranded wires, that is, the alternately twisted collective stranded wires with slack, from the state of strands in a continuous process, almost simultaneously. The purpose of the present invention is to provide a new method for manufacturing a slackened stranded wire and its apparatus, and for convenience of explanation, the method for manufacturing the above-mentioned alternating five-cut, simultaneously slackened collective stranded wire is generally representative of this type of stranded wire. Although the device is shown and explained in the drawings as an example, the spirit of the present invention is not limited to this, but extends to all kinds of stranded wires, and also to a collection of stranded wires. It goes without saying that it is applied regardless of the format, whether it is a layer set or a unit set.

あり、さらに多数ボビンの運搬、管理及びそれらの設備
等の面においても種々の問題点があった。Conventionally, in order to manufacture stranded wire for communication cables such as the above-mentioned 5-quad wire, each element is drawn out from four strand bopins attached to the untwisting feeding section of a quad twisting machine (also referred to as a 4-quad twisting machine). The wire is introduced into a twisted wire winding device while being twisted back, and the wire is collected and twisted and wound onto a winding bobbin installed inside the machine. As soon as the bobbin becomes spiral, the operation of the machine is stopped and the wire is separated. After that, repeat the same operation to form a large number of bobbins in which the quad stranded wire is spirally wound. Next, insert the bobbin into the feeding section of a separate 5-cut stranded wire device. The required number of wires (of course, in this case, 5 wires) are installed, the stranded wires are pulled out from these bobbins, and the twisted wires are condensed and twisted by a wire twisting device, and then wound onto a large-diameter winding bobbin to produce the 5-cut stranded wire. However, since the winding bobbin of the above-mentioned curled wire stranding machine is installed in the stranding machine in which the flyer rotates, the curled stranded wire cannot be taken from this winding bobbin. It is impossible to take out the bobbin and work on the next 5-cut twisted wire machine, so there is no other way than to perform the work in a separate process as described above. It requires a lot of complicated work to replace the strands, and the operation of the machine must be stopped each time, which significantly impedes the work efficiency of the entire stranded wire manufacturing process and only increases the cost of the product. However, the guide twisting machine requires several guide twisting machines for one 5-cut assembly twisting device, and requires an extremely large amount of electric power because it rotates a fairly large twisting mechanism such as a fryer at high speed. Therefore, there are many drawbacks and obstacles, such as severe noise and severe wear and tear on the rotating parts, and there are also various problems in terms of transporting and managing a large number of bobbins, and their equipment.

乱れそれらの選別などにも多くの煩雑な手間を必要とし
た。In addition, in this type of stranded wire, the twists for each quad and the twists in the collective twist are all in the same direction, so when connecting cables made of these, each unidirectional twist must be removed after cutting the cable. This process had to be carried out manually, and as a result, the arrangement of the strands became disordered, requiring a lot of troublesome effort to sort them.

いて交互反転撚りを施した通信ケーブル用の集合撚線が
開発されてはいるが、いまだ満足すべきものの出現をみ
ていない。Therefore, in order to eliminate the above-mentioned complexity in cable connection, a stranded wire for communication cables has been developed in which the stranded wire with alternating twists is applied in the twisting process as a stranded wire with slack. I haven't seen anything satisfying come about.

得なかった。In other words, all of them perform alternating reverse twisting only in the assembly process of multiple rows of twisted wire units, and although the extra length (sag) of each twisted wire unit is maintained, the twisted wire units themselves are the same as before. Since the twisting is done in one direction and the collective twisting is performed in a separate process, it has not been possible to achieve a significant improvement in efficiency in either the stranded wire production work or the cable connection work.

らずその能率は殆ど向上し得なかった。Furthermore, the production of S, Z-stranded stranded wires, which is manufactured from the strands in one continuous process, has been developed, but this requires a very long and heavy filament accumulating device to be rotated forward and reverse. Since it involves twisting, it is impossible to operate at high speed, and although it is a continuous process, its efficiency has hardly been improved.

た。In addition, since this product performs alternating reverse twisting for each maximum amount of filament accumulation, the length of the reverse twist, that is, the unidirectionally twisted part, is extremely long, so it is practically not much different from the unidirectionally twisted one, and For the same reason, the reversing action during alternating reversal is extremely slow, so the untwisted reversing section is long and requires "gluing" to prevent the untwisting of the reversing section, making it difficult to use as a communication cable. There were many problems, such as the tendency to cause deterioration of electrical characteristics, which can be considered life-threatening.

びに接続作業の能率化等に寄与しようとするにある。The present invention has been made in order to solve all at once the many drawbacks, obstacles, problems, etc. in the conventional method of manufacturing stranded wires for communication cables and the device thereof as described above. The process of alternating twist equivalent to the combined cut twist and the process of collective twist with slack such as 5-cut twist can be performed in one continuous process at extremely high speed and smoothly using an extremely rational method and a simple device. The present invention provides a novel method for manufacturing a collective stranded wire with simultaneous sagging and alternating twisting, which is extremely streamlined and highly efficient as a whole, and which incorporates a novel alternating twisting method that does not require any gluing, and an apparatus therefor. The purpose of this is to dramatically improve the manufacturing efficiency of the stranded wires for communication cables, reduce the cost of these products by significantly reducing power and equipment costs, and improve quality by improving the electrical characteristics of the products themselves. The aim is to contribute to improvements, elimination of noise pollution, and streamlining of connection work.

場合によってはローラ１個であってもよい。The twist prevention roller groups 11f to 15f are designed to allow the strands to pass between normal rollers, and allow the strands to pass through but prevent rotation in the direction perpendicular to the axis, i.e., prevent twisting. Other materials may be used as long as they are available, and in some cases, one roller may be used.

They are arranged radially at appropriate positions on the upstream extension connecting the axes of 1B, 19, 20, and 21.

9l, 20l, 21l.
This means keeping the distance L from b to 2lb sufficiently large, but this does not necessarily mean that a long distance is necessary, but it can be adjusted as appropriate depending on the length of alternate twisting and the length of l. This is a delicate matter in conjunction with the action of the simultaneous alternating wire twisting device 2, which will be described later in the present invention, and maintaining the distance between the alternating twisting cap groups 17d to 21l and the collective cap 5A at a close distance. It also has an important awareness that can produce new effects.

る。First, the main drive shaft 55 driven by the drive motor M1 drives the reversing clutch 7 in the simultaneous alternating wire twisting device 2, and the reversing clutch 7 reverses the reversing drive shaft 24 at a predetermined period set by a timer or the like. The central gear 22a fixed to the central drive shaft 22 driven by this is driven in forward and reverse directions, and the external gears 17a to 21a that engage with the central gear 22a are also rotated at a rotation speed determined by their tooth number ratio, that is, a predetermined twist. The pitch is reversed forward and backward, and eventually the alternate twist bases 17l to 217 pass through the alternate twist plates 17b to 2lb provided at the downstream ends of the hollow shafts 17 to 21.
Each group of four strands inserted through the wires is given an alternating reverse twist with the required pitch and reverse twist length, and then converged into the collecting cap 5A, as described above. Alternate twist base 17l~2 for wire W
The strand thread or tape T pulled out from the restraining winding device 3 is wound between the terminal 1/ and the collecting cap 5, and the tendency of the twist at the reversal portion of each alternately twisted wire formed by the above to return is eliminated. At the same time, the twisting device 4(1) and the pulling device 6 prevent the wires from being twisted together with the bundled wire W, and the wires are twisted into the collecting nozzle 5A while fixing the twist.

込まれ撚りが固定されるのである。In other words, this twist fixing action is carried out instantaneously at a close distance, so there is no time for untwisting to occur, and the groups of alternately twisted wires in multiple rows (5 rows) and multiple wires (4 wires) are arranged in a predetermined alternating manner. While the twist pitch and alternating twist length are completely maintained, the pieces are twisted together with the restraint winding T into the collection base 5, and the twist is fixed.

回転の向きは互いに逆向きで回転する。In this way, the multiple rows of bundled wires W, which are alternately twisted for each strand group by the simultaneous alternate twisting device 2, are put together in the collecting cap 5A while being subjected to a restraining winding T, and then the bundled wires W are twisted alternately in each strand group by the simultaneous alternating winding device 2. The first one-time applying device 4 (
1) After entering the hollow shaft 44 and winding the spiral roller 41 once, it passes through the hollow shaft 54 of the restraining winding device 5 and reaches the second winding device 4 (2), where it is wound around the winding roller 41' once. It is wound and goes to the downstream take-up device 6 through the hollow shaft 44'. 1 twist applying device 4(l), 4(
The twist pulleys 41, 41' in 2) are running line W
It periodically rotates forward and backward around its central axis, and the directions of rotation are opposite to each other.

において集束線ＷにＳ撚りが与えられて撚り合される。That is, if the first twist pulley 41 rotates clockwise when viewed from the upstream side, the second twist pulley 41' rotates counterclockwise, and the first and second twist pulleys 41' rotate in the counterclockwise direction. a focusing line W between devices 4(i), 4(2),
More specifically, the S twist is given to the convergent wire W in the portion from the point P where it exits the first one-turn pulley 41 to the point Q where it enters the second one-turn pulley 41' and the wires are twisted together.

与されるわけである。However, the twisting of the lever is done by the opposing one-turn pulley 41,
41' are rotated in opposite directions and twisted, so the convergence line W is given a round twist in the same way as when a towel is wrung out by hand, and the degree of twist is the same even if the rotation speed is the same. In this case, twice as much twist is applied compared to the normal case.

Forming various twist states by taking values in relation to the rotational speed, reversal period, distance between both pulleys, and running speed of the running wire W with respect to the effective circumference length of 1.41'. I can do it.

値を選定すればよい。However, those settings are, for example, both pulleys 41, 41'
As long as the diameter of the pulley, the distances P and Q between the two pulleys, and the running speed of the wire are kept constant, this can be done very easily by changing the rotational speed or reversal period of both pulleys as appropriate. , a value suitable for the configuration of the line may be selected.

集合撚線が形成されるのである。The bundled wire W twisted in this way is fixed in its twist by unwound yarn or tape 〒' pulled out from the restraining winding device 5 at the same time as the twisting, and is attached to the winding device 7 via the downstream pulling device 6. The wire is wound up on the winding pobbin 72, and a set of five alternately slackened wires as shown in FIG. 4 is formed.

A set of stranded wires with alternating five-cut simultaneous slack windings T and T' is shown.

lb and the distance L between the twist suppression roller groups 11f to 15f, the alternating twist plates 17b to 2lb, and the alternating twist caps 17l to 21
7, the distance l from the alternately twisted plate groups 17b to 2lb to the alternately twisted cap groups 17/ to 21l is as long as it does not impede the passage of the strands. If the distance is close and the distance L is kept sufficiently large compared to the distance l, the alternating twisted plate group 17
By forward and reverse reversal of b-21b, alternate twisting cap groups 171-
When the above-mentioned specifications are set so that the alternating twists given to each wire group at No. 21 have the required twist pitch,
On the upstream side of the alternately twisted plate groups 17b to 2lb, the twist pitch is extremely rough, forming a gentle twist, and the entrance angle α' to the alternately twisted plate group 17b to 2lb is the exit angle on the downstream side. There is sufficient time for the twist to proceed until it reaches the same angle as α, and the progression of the strand group is prevented from passing through the strand passing holes in the alternately twisted plate groups 17b to 2lb. In addition, as already mentioned, in the present invention, since the twisting direction is reversed within a range where the twisting direction is reversed, the twisting direction is alternately reversed within a relatively short period. The wire passes through the wire passage holes of the twisted plate groups 17b to 2lb, and on the upstream side, the state of unidirectional twisting and twisting O with a rough and gentle twisting pitch is repeated, and on the downstream side, the twisting state is repeated. As mentioned above, when the alternating twist is applied, it is twisted all at once into the collecting nozzle 5 while being restrained almost at the same time, so that a stable alternating reversal twist having the required twist pitch can be smoothly and satisfactorily obtained.

用の撚線が得られるのである。Of course, when performing alternating reverse twisting, the shorter the reversal time, the shorter the untwisted portion of the reversed portion, which is preferable from the point of view of electrical connection as a communication cable. In the present invention, as already mentioned, the mass of the reversed parts such as the alternately twisted plates 17b to 2lb, the central gear 22a, and the external gears 17a to 21a is extremely light and small, and compared to the conventional one, the mass of the reversed parts such as the alternately twisted plates 17b to 2lb is extremely light and small. Since it can be constructed using less than one-tenth of the amount of stranded wire, the reversal time is extremely short, and since no gluing is applied at all, an extremely good stranded wire for communication cables can be obtained from this point of view. .

有するものである。As detailed above, in the present invention, the distance L on the upstream side of the alternately twisted plate groups 17b to 2lb is maintained sufficiently larger than the distance l on the downstream side, and the distance l and the alternately twisted base plate are 177 to 21l, the collecting cap 5A and the restraining winding device 3 are arranged at a close distance, and the simultaneous alternating wire twisting device 2 is used to twist multiple (4) strands in multiple rows (5
rows) at the same time lightly and smoothly with a relatively short cycle, and while converging and twisting them, alternately twisting them, and instantaneously applying restraint winding T between the twisting cap groups 17l to 21l and the collecting cap 5. The process of forcibly twisting into the collective cap 5 and the opposing first and second twist applying devices 4 (
1) and 4(2), as if squeezing a towel with both hands, alternating reverse twisting is applied to the converging line W at a twisting speed twice the normal twisting speed with an even shorter cycle, and at the same time, the restraint winding T is again applied. The process of fixing the twists by fixing the twists and winding them is carried out almost simultaneously in one continuous process, so that the twisting is extremely stable and the electrical characteristics can be improved without giving any untwisting to each strand. A communication cable that can smoothly form high-quality alternating stranded wires with slack without applying any glue at high speed, eliminate unnecessary labor such as replacing bobbins, and can be manufactured with extremely high overall efficiency. The production cost as a typical stranded wire unit for use is greatly reduced, and the method and equipment are more rational and simple than the conventional manufacturing method and equipment that involve separate processes, as well as other methods and equipment for twisting twisted wires. Since it can be manufactured, the equipment cost is extremely low, the power consumption is less than one tenth of that of conventional communication cables, noise pollution can be eliminated, and it is also convenient in terms of connecting cable cores. The present invention has numerous advantages as a method and apparatus for producing a collective stranded wire with alternating twist and simultaneous slack for use.

、多種多様の撚り状態を任意に得られる利点もある。Furthermore, since the settings of the alternate twisting device 4 can be freely and variously changed according to various wire types and wire diameters, there is an advantage that a wide variety of twist states can be arbitrarily obtained.
