Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a layer twisting apparatus 1't1, and more specifically to a layer twisting apparatus 1't1 for producing a layered wire consisting of two layers, an inner layer and an outer layer.

Conventionally, when producing this German layer stranded wire, the inner layer was
Two wire twisting devices, u li':j and a device for twisting the outer layer onto the inner layer wire, were required, and the machine cost and installation space for two devices were also required.

The present invention has been made to eliminate these conventional disadvantages, and its purpose is to provide a novel layer-twisting device that can produce layer-stranded wires in a single machine.

Before explaining one embodiment of the present invention, in the layer twisting apparatus of the present invention (the layer twisted wire produced thereby is shown in FIG. 1, the inner layers are aligned by a plurality of inner layer wires W1, A plurality of outer layer lines V on top of the .

The outer layer is twisted and layered to form two inner and outer layers of twisted wire. In this case, the twist directions of the inner and outer layers are opposite to each other, and if the inner layer is S-twisted as in Hanji,
The outer layer is Z-twisted.

An embodiment of the present invention will now be described with reference to FIGS. 2 and 3. A hollow flyer 2 is rotatably supported between bases 1.1 which are erected facing each other, and guide rollers 24, 25, 26.degree. 27 are provided along the frame. One end of the fryer 2 is supported by the base 1 via a hollow shaft 28, and a main pulley 21 is fixed to the other end, which is rotated by a motor M.

A floating frame 3 is suspended inside the flyer 2 so as to be rotatable with respect to the flyer. Near the end of the floating frame 3 opposite to the hollow shaft 28, a feeding device 22 for the outer layer line t2 and an outer layer line segment line plate 30 are arranged. Internal bases 4 and 5 are erected facing each other in a space on the floating frame 3 on the side opposite to the part where the outer layer wire sending devices 22 and the like are arranged.
A common drive shaft 12 passing through the cylinder internal bases 4 and 5 is driven through a gear 29A1 fixed to the inner end of the hollow shaft 28 and a gear train 29 that engages with the gear 29A1. An internal flyer 6 and a winding bobbin 7 are installed on the internal bases 4 and 5, and their configuration and 1. The U i relationship will be explained below with reference to FIG.

The internal flyer 6 is rotatably supported on the internal base 4 via a hollow internal flyer east 1161, and is rotationally driven from the common drive shaft 12 via a boot I+-11 fixed to the internal flyer 't++l+ 61. . Internal fryer 6
For the cab scan rollers 8A, 8B, f, C keys (

iB:! The sun gear 10 is fixed on the J platform 4.
By being held against the inner fryer 6, the inner fryer 6 is rotated and moved together with the rotation of the inner fryer 6. A winding arm 62 extends from the flyer 6, and a winding roller 62A is provided at one end of the winding arm 62.31. Ru.

The internal base 5 has a hollow cylindrical bobbin 1 drive (11111
16 is rotatably supported, and this bobbin driving water 1116
All four have pulleys 11 fixed to them and are driven one rotation by a drive shaft 12. A cam pulley 15 for driving the T-mouth and rubber is rotatably supported by a rotary support 71 fixed to the internal base 5 and a gnome 13, and is rotated (driven) by a common drive shaft 12.

Bobbin! ill 14 is a traverse shaft portion 14 in the longitudinal direction.
A.

It has a main portion 14J3 and extends over both the rotation support frame 13 and the internal base 5. The traverse l1lJ, 1st part 14A is the Cambu IJ-1 mentioned earlier.
The key part 14B is engaged with the inside of the bobbin drive 11.
They are engaged with the inner wall of the i1116 so as to be slidable in the axial direction, and to be prevented from rotating in the rotational direction by some of the keys.

A drive plate 19A of the Masatsu clutch 19 is fixed to the end of the bobbin 14 opposite to the traverse shaft +4A, and a shaft extending from the drive plate 19A receives the bobbin rotation +t1+IB via an appropriate bearing. The bobbin rotating shaft 1 is rotatably provided, and a winding bobbin 7 for the layered wire of the bobbin rotating shaft 1 B & C11J product is attached thereto.

At the end of the bobbin rotating shaft 18 there is a mounting plate 19. B is attached and engages with the drive plate 19A described above to form a clutch that can slip in the direction of rotation when an I-lux is applied above a certain limit. This winding bobbin 1
The position is opposite to the above-mentioned internal flyer 6 and corresponds to the inner side of the winding arm 62 thereof.

Also, the rotation of the winding hobbin 7, the direction of the disturbance, and the direction of the rotation of the pulley 17 are i, l, 3 flyer 6.
, and of course the speed is faster than the rotation of the internal flyer 6 by the amount required for winding.

Next, this invention device dt will explain the layer stranded wire JiξIJ, and the center 4''.A predetermined number of inner layer gauze W7, 2'-
Prepare and pass these through the inner layer/wire twisting die 23 to the C medium wire 128, Q-person, and guide (Cola 24, 25
．． 76 and 27 with diameter 11, 2jj=<.

In this state, when rotating the fryer 2 in a clockwise direction from the right end in FIG. 2 at a rotation speed N, the inner layer line 7υ.

receives two S twists and enters the center hole of the C outer layer wire segment plate 3o, and during this time a predetermined number of outer layer wires w2 are sent out from the sending device 22 and merged to the outside.゛Since the internal flyer 6 rotates in the same direction as the fryer 2 at the same number of rotations N, is it the inner layer line after all? , is 2N-N=N rotation S, outer layer W2
receives a Z twist of N rotations 0-ノ, these inner and outer 2 i+!
1 enters the internal flyer shaft 61 as a layered wire with twists in opposite directions, and is taken up by the capstan 8.
The internal flyer 6 is wound onto the winding bobbin 7 by rotation of the arm 62.

In this slot fit, the bobbin 7 of the winding 17 is also driven to rotate at a rotational speed n greater than the same direction as the inner iSb flyer 6.

Now, if the take-up length of the capstan 8 during one turn of the flyer 6 is 41 turns, and the diameter of the winding body of the take-up bobbin 7 is d, then (n −1”J )πd=t. The rotational speed n is set according to f.The value of d increases as the winding of the layered wire around the winding bobbin 7 progresses, so the MiJ notation is satisfied when the internal flyer 6 and the winding bobbin are used. The above (10) ji until the full volume is determined.
While i increases, it is preferable to make the clutch 19 slip by that amount so that fS is smaller than the 1 shift setting of n.

The winding bobbin 7 is axially reciprocated integrally with the bobbin shaft 14 which reciprocates by the rotation of the cam pulley 15, that is, is driven to wind and traverse. In this way, the layered wire of the product is wound up on the winding bobbin 7i.

According to this invention, as described in detail above, since layered stranded wire can be manufactured with a single machine, it is possible to reduce not only the cost of the machine itself but also the installation space, etc.
In addition, the advantages in terms of manufacturing control are extremely significant.
