Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for manufacturing a flexible conductor, more specifically, an apparatus for manufacturing a flexible conductor that requires high flexibility, such as a machine string used in a telephone set 1 or a telephone exchange. It is related to.

Conventionally, as a manufacturing device for a flexible conductor such as a telephone string, there is a device for horizontally winding a conductive alloy wire such as a copper or tin alloy wire around the length of a core thread such as a Tetoron thread; Alternatively, a device for horizontally winding an alloy foil wire is known.

However, in the former of these conventional devices, when the conductive wire is closely wound around the core thread, the amount of conductive wire required reaches a considerable amount. It is difficult to adjust the feed speed and winding speed (rotation speed of the core yarn), and if the tension of the alloy wire being wound is not adjusted reliably, the finish of the product conductor will be poor. When using alloy foil, alloy foil bobbins are attached to the winding conductor delivery device, and these bobbins are rotated for one part of the core yarn, which is extremely inefficient, and the machine must be stopped each time the bobbin is replaced. However, there were many disadvantages such as the complexity of factory management.

The present invention provides a new and high-performance flexible conductor manufacturing device that eliminates the drawbacks of these conventional devices,
(1) Since the material to be wrapped is wrapped in foil, the amount of material can be reduced significantly. (11) The winding pitch of the conductor wire is widened, so the take-up speed of the core wire can be increased. (iii)
) The rotational speed of the core thread and its feed rate can be changed in relation to each other. (IV) If only a round conductor wire is prepared as the wire to be wound, it can be rolled into foil and used. (V) Winding. It is characterized by the ability to completely adjust the tension of the attached wire.

An embodiment of this invention will be described with reference to the drawings.

1 as a whole is a feeding device for a thread C such as a Tetoron thread, and a frame 11 carries a thread bobbin 12, is rotatably supported by a hollow shaft 14, and a frame 11 carries a thread bobbin 12.
It is rotationally driven from the common drive shaft 5 by the rotor 13.

What is indicated by 2 as a whole is a take-up device, and the base 21
A hollow shaft 22 is rotatably supported, a gear 22a is fixed near its upper end, and a drive gear 22b is fixed below the shaft.

A hollow shaft 24 is again rotatably supported at the central axis position of the hollow shaft 22, and a frame plate 2 is attached to the upper end of this hollow shaft 24.
A sun gear 24a1 and a pulley 24b are fixed to a portion below the sun gear 24a1 protruding from the hollow shaft 22 below the octopus.

There are two capstan drums 26 on the top of the 7-ray 423.
, 27 are rotatably supported as shown in FIG.
Each rotating shaft extends downward through the frame plate 23, and has gears 26a and 27a fixed thereto, and both gears 26a and 27a mesh with the gear 22a.

Planetary gears 25a and 25b are respectively fixed to the upper and lower ends of the rotating shaft, which is attached to the base 21 parallel to the hollow shaft 22 and rotatable relative to the base. The gear 24a meshes with the gear 24a, and the gear 25a engages with the drive gear 22b of the hollow shaft 22.

The upper part of the frame board 23 is provided with a guide guide for guiding the filament.
= 28a and 28b are attached with appropriate brackets (not shown), and the conductor ω is wound by pressing the button on the conductor winding guide device indicated by 3 above the take-up device 2, and the core thread becomes a product conductor. C enters the capstan drum 27 via the guide pulley 28a and enters the capstan drum 2.
After being wrapped an appropriate number of times between 6 and 6, the guide poo '17
-28b, and proceeds downward through the interior of the hollow shaft 24.

What is generally indicated by 4 is a winding device for a product conductor, in which 41 is a base, 42 is a rotating frame rotatably supported on the base 41 via a hollow shaft 42a, and 42b is a rotary frame supported on the hollow shaft 42a. A pulley 43, which is fixedly fixed and transmits the rotation of the common drive shaft 5 to the rotating frame 42, is a traverse shaft passing through the inside of the hollow shaft 42a, and a winding bobbin 44 is attached to the upper end of this traverse shaft 43. A drive pulley J43a is fixed in the middle, and its lower end is rotatably supported by a traverse arm 45.

Note that 46 is a cylindrical cam for traverse, and its rotation causes the traverse arm 45 to reciprocate in the upward and downward directions, thereby reciprocating the winding bobbin 44 in the upward and downward directions.

What is generally indicated by 8 is a delivery part for the conductor W to be wound around the core yarn C, and in the illustrated embodiment, there are a total of five delivery bobbins for the conductor W having a circular cross section, 81, 82, . . .
...85 is drawn.

What is indicated by 7 as a whole is a rolling device that rolls the conducting wire W into a conducting foil, and is composed of a pair of rolling rolls 71 and 72.
One of the rolling rolls 72 is driven one rotation from the common drive shaft 5 via a worm 73 and a worm wheel 74.

The conductive wire W made into a foil in this rolling device 7 is guided as a whole to the conductor winding guide device 3 described above through a tension adjusting device 75.

The tension adjustment device 75 is a dancer roller type including rollers 75a, 75b, and 75c, and the roller 75b is pulled by a tension adjustment tension spring 75d, and this tension spring 75d has its tension adjusted by an adjustment screw 75c. adjusted.

As is well known, in the illustrated configuration the tension spring roller 7
If the pulling force of 5b is T, then the tension of the conductor W at that time is T/2.

The entire apparatus described above is operated by driving the common drive shaft 5 one rotation by the prime mover 6.

That is, to explain it again, the common drive shaft 5 is the pulley 13 of the yarn feeding device 10, and the pulley 24b1 of the take-up device 2.
Pulley 42bX button and pulley of winding device 4) 43
Rotate drive a.

The common drive shaft 5 rotates a traverse cylindrical cam 46 via a reduction gear device 9.

In this case, pulley 13, pulley 24b1, pulley 4
2b is set to have the same rotation speed.

As is clear from the configuration of the device of this invention described above, the core thread C
The core yarn is fed out while being rotated around its own axis from the core yarn feeding device 1, and after being closely wound crosswise around the conductor W in the conductor winding guide device 3, it is taken up by the take-up device 2, and then taken up by the take-up device 4. The winding bobbin 2 is closely wound.

For the device of this invention, (1) Since the conductor W to be wound is rolled into a foil by the rolling device 7, the amount used is 40 to 50% less than that of a round conductor 11, and It is sufficient to install a bobbin made of an ordinary round conductor with a circular cross section. (i1) The bowing speed of the core yarn C can be increased, that is, the speed can be increased. (iii) If a rolling device such as -i is not used, It is also possible to wind the conductor 11 times; for example, by using a conductive wire instead of the core thread C and wrapping six round conductors around it from the periphery, it can be used to produce a so-called seven-stranded wire. You can also do it.

(IV) complete tension adjustment is possible with a dancer roll type tension adjustment device 75; (V) a hollow shaft 22 for driving the take-up capstan drum in the take-up device 2;
Since the hollow shaft 24 that rotates the frame plate 23 for rotating the thread C is interlocked with the hollow shaft 24, the rotation speed of the thread C for winding the conductor and the take-up speed thereof change in relation to each other. However, it has many advantages and effects, such as once set, it is possible to always close and close the winding.

Although not shown in the drawings, a twice-twisting mechanism may be employed as the yarn feeding device 1 button and the winding device 4.

At this time, between the sending device 1 and the take-up device 2, the core yarn C remains with one degree of twist and progresses while being rotated at the rotational speed of the flyer of the two-degree twisting machine.
The conductor W is wound around this.

Thus, the remaining one-degree twist is also eliminated at the stage of winding onto the winding bobbin of the winding device.
