Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to single wires, multiplex wires, cables, twisted ropes, etc. that are wound around a spool using a flyer.
A linear object such as a wire or glass fiber (hereinafter simply referred to as a line for the sake of simplicity) is
It relates to a method for first storing on a spool or the like and then withdrawing from the scroll, spool or the like for further processing.

When winding wire onto a spool using a flyer, the wire is first introduced into the winding device from the axial direction of the spool, and is then deflected by a roller so that the wire is tangentially rolled onto the spool core. placed. At this time, the line is approximately
Can undergo 360° twisting.

In the prior art, wire was introduced tangentially to the spool and wound directly onto the spool core. In the case of such a winding device according to the prior art, the spool rotates. To further process the wire once it has been spooled, the wire is pulled tangentially off the spool. At this time, the spool rotates again. In this case the wire does not undergo twisting.

However, such conventional methods are particularly disadvantageous when the wire processing operation is carried out in continuous operation and a large amount of wire is required for this operation.
That is, the entire line wound on a spool is withdrawn and the process must be interrupted each time the spool is empty. first,
The end of the line on the empty spool must be joined to the beginning of the line on the next spool. To avoid this splicing operation and the associated loss of time, a very large spool would be required, capable of winding very long lines. Naturally, a spool wound with such a long wire is very heavy and difficult to handle. Moreover, since the spool rotates when drawing out the line, special braking means must be provided for the spool in order to maintain a constant load on the line during drawing out.

The disadvantages of winding the wire around the spool and withdrawing the wire from the spool can be avoided by withdrawing the wire beyond the end of the spool for further processing. This is because in this case, the spool remains stationary both during winding and unwinding. In this method, the load on the wire is extremely small. Moreover, the line end of one spool can be joined to the line start of a new full spool without interrupting the next processing operation.

However, problems similar to those described above arise when a cable installation has to be carried out by pulling, for example, an underground cable from a spool that has been wound on a spool using a flyer, or from a cable wrap over the end of the spool. . That is, such cables tend to form tortuous serpentine lines during installation due to their twist. This is not desirable. In order to eliminate this problem, West German Patent Publication Specification No.
The proposal disclosed in No. 3102101 does not straighten the twist of the cable so that the cable can be laid in a straight line, but it uses a straightening device to straighten the meandering line bend caused by the twist. will be guided.

The problem of twisting as mentioned above can be caused by, for example, multiple
This is particularly the case if, for example, four wires are simultaneously drawn from each spool by one flyer and these wires are to be insulated by enameling after drawing, for example to join together an electrical cable. In this case, it is necessary to separate the wires from each other after they are drawn from each spool, and if the wires were already in a "twisted" state at the time of drawing, it would be impossible to separate them. Become.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a method by which a twisted wire or a wire bundle consisting of a plurality of wires can be drawn out without twisting.

This object is achieved by the features of claim 1. That is, if the wire is drawn axially from the spool of wire over the end of the spool in accordance with the claimed method, the wire will be drawn from the spool or the spool without twisting. was discovered.

For example, when the wire is pulled out from the outside of the scroll in the axial direction beyond the end of the spool, the wire is pulled out in the same direction as the original wire introduction direction, and there is no twist. If the line were drawn out in the direction of the extension of the original direction of introduction, the twist would be strengthened.

If the inside of a wire-wound coil is hollow, for example, in a conical shape, and the wire is pulled out from inside, the twist applied to the wire can be removed by pulling the wire out in the direction of the extension of the introduction direction. It will be canceled.

For practical technical reasons, it is expedient to mount a spool with a conical core vertically, with its larger core diameter facing up during winding, and to wind the wire onto this core with a flyer. There are many cases. Therefore, when drawing out the wire, it is advantageous to remove the winding core and then draw the wire out from the inside through the wider coil opening that opens at the top. This is because, in this case, the heavy spool does not rotate during wire drawing. However, in this case the twist of the wire remains. Therefore, according to the present invention, after the wire is drawn out through the interior of the coil, the wire is turned downward and guided, thereby untwisting the wire and releasing the twist. The wire therefore emerges from the scroll in an untwisted state.

In order to create such a hollow space, a flyer is used to wind the wire around a spool which is known per se and has a conical winding core, and the winding core is removed for drawing out the wire.

Drawing the wire axially over the end of a spool or roll in this manner is particularly advantageous in tube- or cage-type wire laying devices. A plurality of wire-wound coils or a plurality of spools wound with wire are arranged one behind the other when viewed from the twisting direction, and the plurality of wires drawn out from these coils or spools are guided to gather at the twisting point. be done. In such a device, the invention allows all spools to be arranged stationary and fixed. Therefore, unlike in the prior art, there is no need to move large masses during twisting. The drawing direction of the wire can be parallel to the rotation axis of the twisting device. Furthermore, the drawing direction may be perpendicular to the rotation axis of the twisting device or oblique at an angle to the twisting direction. Previously, the rotary spools associated with such devices required expensive braking devices, but with the present invention such expensive braking devices are no longer necessary. In order to guide the wires to the twisting point with the necessary tension, it is sufficient to brake the deflection rolls associated with each wire accordingly.

The invention is particularly advantageous in rope making machines called strand machines. In this machine, multiple wires are wound around a single core wire in multiple layers. This winding must be carried out in an orderly manner without any disturbance. Especially when twisting, each wire must not have any bends. Such line tortuosity is likely to occur when strand formation is carried out at high speeds. This is because there are often differences in the running speeds of the individually guided lines. If twisted strands of wire are produced that are not twisted together in an orderly manner, the electrical quality of the strand is adversely affected over its entire length. Moreover, such irregularly twisted wires increase the cost of the insulating material. Since the insulating material is derived from crude oil, twisted wires that are stranded result in a substantial increase in the cost of manufacturing the electrical cable.

Therefore, it is an object of the present invention to enable twisting of strands to be carried out quickly and orderly.

The present invention achieves this object as follows. That is, the plurality of wires required for one layer or at least a portion of the plurality of wires necessary for one layer are twisted and wound onto one spool, and the plurality of wires are twisted from the spool during twisting. The wire is pulled out in such a way that it is untwisted and fitted into the strands. According to this method, even if the twisting is carried out at very high speeds using a fryer, for example, there will be no difference in running speed between the wires. For example, the fryer can be rotated at a high speed of 2000 revolutions per minute for twisting. In order to obtain the desired length of twist during twisting, the spool for winding up the strand may be simultaneously rotated at a speed greater than the flyer, for example by about 100 to 150 revolutions.

Other features and details of the invention will be understood from the claims, the drawings, and the detailed description based on the drawings.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows how a flyer is used to wind wire onto a spool.

With the flyer 2 pivoting about the axis A--A, the wire 4 coming from the direction of the arrow A is wound onto the core 5 of the spool 6, which remains stationary.
For this purpose, the wire 4 is guided by deflection rollers 7, 8, 9 in such a way that it lies on the spool core 5 in the wire direction. Connect this line to the flange 11 of the spool.
The flyer 2 moves up and down in the direction of the arrow 10 so as to sequentially wrap the flyer between and 12.

Line 4 is subjected to twisting in the direction of arrow 13 by rollers 8 and 9 pivoting in the direction of arrow 1 about axis A--A. Due to this twisting, the wire is sequentially placed one layer at a time on the winding core 5 of the spool 6.

Once wound onto the spool, the wire 4 retains its twist when it is pulled out of the outer layer of the spool in the direction of arrow 20, as shown in FIG. This is not necessarily desirable for the next stage of processing.

When the wire 4 is pulled out from the outside of the spool in the direction indicated by the dashed line 21, the wire 4 undergoes further twisting as indicated by the double arrow 22. In this case, the lead-out direction 21 of the line is the extension direction of the lead-in direction 3.

However, when the wire is pulled from the spool from the outside in the direction of arrow 23, the winding twist shown by arrow 13 is superimposed by the unwinding twist shown by arrow 24. Both twists cancel each other out. The wire 4 therefore leaves the spool 6 in the direction of the arrow 23 without twisting. Line derivation direction 23 in this case
must be in the opposite direction to the introduction direction 3.

The wire is withdrawn from the spool by means of a specially constructed withdrawal device, for example a flyer-like roller which pivots in the opposite direction to the flyer 2 of FIG. 1 and is constructed to guide the wire in any suitable direction. It can also be carried out using a system.

It has proven advantageous to use the spool shown in FIG. In the case of this spool, its winding core 30 is constructed with a slightly conical shape, so that the winding layer 31 is correspondingly placed on the winding core 30 in a conical shape. The upper spool flange 32 is formed into a conical shape. Therefore, when drawing out the wire 33, the wire 33 is easily drawn out beyond the spool flange from the corner of the spool flange and the winding core. In this configuration, the wire is pulled out over the edge of the spool flange 32, so that
4 is formed in the shape of a drawing ring.

The lower spool flange 35 forms an obtuse angle with the winding core 30, so that the wire can also be easily pulled out from this corner 36.

The spool of FIG. 3 can be very large, so the weight of the spool when wound with wire can be very large. Therefore, the spool may be transported on rollers 37, 38, 39 for transportation.

FIG. 4 shows a spool 40 having a core 42 formed into a conical shape with a large slope. In the case of this spool too, the winding layers 45, 46 are arranged in a corresponding conical shape. In the space 47 between the spool flanges 41 and 43, a winding wire wound conically in multiple layers is placed, but in this case, the outer shape of the wire coil is cylindrical. The number of winding layers gradually decreases toward the bottom as shown. The wire wound around this spool is wound by introducing the wire from the introduction direction 3 using the flyer 2 shown in FIG.

When this line is pulled out in the direction of arrow 48 for the next machining operation, it will retain its twist. When a line is drawn using rollers 49, 50, 51 rotating in the direction of arrow 14,
The wire leaves the spool in the direction of arrow 52 without twisting.

In the case shown in FIG. 5, the wire is wound by a flyer (not shown) in such a way as to form a conical winding layer on the spool 52 from the direction of introduction 3, but as shown in FIG. The spool is wound with the spool oriented so that the larger diameter side of the core is on the lower side. To draw out the line, turn this spool upside down and attach it to the fifth
The state is shown in the figure. That is, in the state for drawing out the line in FIG. 5, the larger diameter side of the winding core is on the upper side. Furthermore, the spool flange (not shown) located on the upper side at this time is removed for drawing out the wire. Moreover, in the case of this configuration, in order that the winding core 53 is also pulled out from the spool 52 in the direction of the arrow 54, the winding core 53 is moved in the direction of the arrow 54 at least as far as the winding core 53 by using the spool 55. Inner wire wound layer 56
can be moved a distance sufficient to create a space 57 between them. Starting from the inner end 58, the wire is drawn out from inside the coil through the space 57 in the direction of the arrow 59. This lead-out direction 59 is opposite to the lead-in direction 3, so that the wire leaves in an untwisted state.

The task of turning a heavy spool of line over and over is a tedious task, and one would often want to avoid it. In this case, the wire may be directly wound on the spool arranged as shown in FIG. 5, that is, on the spool with the larger diameter side of the winding core facing upward. In order to draw the wire out from inside the coil without twisting, it is therefore necessary to draw the wire downward through the narrow opening of the coil. However, this is not desirable. This is because there is a risk that at least the winding loops of the innermost layer may be displaced from each other or may be caused to slip downwards together. A method for dealing with this is shown in FIG. That is, the wire on the spool, in a position similar to that in FIG.
70, it is deflected downward and exits the coil in the direction of arrow 171. In this way, the wire can be drawn out from the spool in an untwisted state without any problems.

In order to prevent the upper wire winding layer 60 from being entrained and coming out from inside the coil when the wire is drawn out using the method shown in FIGS. 5 and 14, the upper wire winding layer is provided with a plate 61. A weight is placed on it.

In this configuration, the end 62 of the line remains stationary during the drawing process. Therefore, the drawing start end 63 of the line on the next spool is connected to its terminal end 62 and position 6.
4, they can be spliced while the machining operation is in progress. Therefore, it is no longer necessary to interrupt the machining operation each time the spool is empty.

FIG. 6 shows coils 65 and 66 of wire wound around two juxtaposed conical cores. After winding is completed, the wire is pulled out from the coil 65 for the next processing operation from the wire starting end 67 of the innermost coil 65. The wire end 68 of this coil 65 is the fifth
As mentioned above with respect to the figure, another coil 6
Therefore, when all the wires of the coil 65 are drawn out, the wires are drawn out from the next coil 66 continuously without any interruption. Of course, further coils can be arranged one after the other after the coil 66, and their wire ends and wire beginnings can be connected in advance.

FIG. 7 is a sectional view showing a tube type twisting device. Coils 71, 72 and a larger number of coils (not shown) are arranged in sequence within a tube 70 that is rotatable about axis BB. All coils within the tube are stationary. That is, these coils do not rotate together with tube 70.

Again, each coil consists of a wire wound around a conical core. The wire is then drawn out from the winding core. The coil is arranged so that the direction in which the wire is drawn out is opposite to the direction in which the wire is introduced when the wire is wound around the core, that is, in a direction that eliminates twisting when the wire is drawn out. line 7
3 and 74 are guided through guide eye holes 75, 76, and 77. These lines therefore rotate with the rotation of tube 70. The wires then pass through a rotatable perforator 78 to the twisting point A, where they are twisted. The wire is drawn out from the coil by the pulling force of a draw-out roll 79 around which the twisted wire is guided. After this, the twisted wire can be guided to a spool 83 via deflection rolls 80, 81, 82. This spool 83 has an axis D-
Rotatable about D, the twisted wire or pile is wound onto the core 84 of the spool. The deflection roll 82 is movable back and forth in the direction of the arrow 85, thereby allowing it to move back and forth during winding, thereby providing the necessary line placement during winding. Since the pile is introduced tangentially onto the winding core 84 and tangentially wound, the pile is not twisted at all during this winding. Instead of the rotary spool 83, a flyer winding device as shown in FIG. 1 can also be used in this case as well. In this case, when the cable is fed out for further processing, the cable should be pulled out from the spool in an untwisted state and the cable should not be coiled or subjected to additional twist. It is necessary to do this.

FIG. 8 is a sectional view showing a cage type twisting device. The operation of this device is basically based on the seventh
This is the same as the tube type twisting device shown in the figure. The mutually connected cages 86, 87, 88 have an axis G--G.
Rotate around the center. The wire wound coils 90, 91, 92 in each cage are stationary. In other words, it is installed so that it does not rotate together with the cage.

In the embodiment of FIG. 8, the wire is wound around a spool constructed as shown in FIG. pulled out towards. A guide roller 93, 94 is subordinate to each coil. One roller of each set of rollers is braked with the required tension to bring the lines together at the twisting point.

As understood from FIG. 8, the coils 90, 91, 92 in this twisting device can be arranged in any direction. To illustrate the various possible coil arrangements, coil 90 is shown in FIG.
is arranged such that its axis J-J is inclined at a certain angle with respect to the coil axis GG, and the coil 92 is arranged so that its axis K-K is coaxial with the coil axis GG. There is. All of these arrangements are examples of coil arrangement directions. The twisting process is the same as for the tube type twister of FIG.

In the embodiments shown in FIGS. 9 and 10, one spool 100 has four wires 111, 112, 113, 1.
A wire bundle 102 consisting of 14 wires is wound in advance using a flyer. This wire bundle 102 is twisted so that four strands form one rope-like rope. Flyer roller 1 rotating around spool 100 in the direction of arrow 115
03 and 103', the wire bundle 102 is untwisted and pulled out from the spool so that each wire of the wire bundle exits the deflection roller 104 as strands 111-114. One deflection roller 1 for each wire

The wire leaving the enameling device is guided via deflection rollers 107 to one roller 108 . This common roller 108 further guides the four wires as a parallel wire bundle. Flyer 10 rotating in the direction of arrow 116 about axis KK
By 9, these lines are again "twisted" and wound onto one spool 120.

According to the prior art, this method is based on a spool 100 in which a plurality of strands of the wire bundle are arranged in parallel and in contact with each other.
It was carried out wrapped around. and spool 1
00 was mounted rotatably about axis A--A, while rollers 103 and 103' were fixed. The wire bundle is unwound from the rotating spool via these fixed rollers 103, 103' and

30 and guided via rollers 134 and 137 to a perforated disc 138 and further guided through a hole in the middle of this perforated disc to a fryer 140.

A wire bundle consisting of, for example, six strands is pulled out from the spool 131. This wire bundle is wound around the spool 131 using a flyer, for example, in the manner shown in FIG. 1, and therefore the wire bundle is leaning on itself. The wire bundle on the spool 131 is pulled out so that the wires are untwisted. Therefore rollers 135 and 13
7, each strand can enter the hole 151 of the perforated plate 138 in a separated state. 1st
As shown in Figure 3, these holes 151 are arranged concentrically with the holes 150 for the core wire. A wire bundle consisting of, for example, 12 strands is pulled out from the spool 132. Similarly to the above, this wire bundle is also twisted when wound onto the spool. In this case as well, the wire bundle is untwisted after passing through the deflection rollers 136 and 137, and these strands pass through the corresponding hole 152 which is arranged concentrically with the hole 151 of the perforated plate. selected so that it can be guided through. In this way, the flyer 140
The six strands guided from the spool 131 through the hole 151 are twisted when the fryer turns, and the six strands guided from the spool 131 through the hole 151 form a first layer around the core wire, and then the spool 132 The 12 strands of wire guided through the hole 152 from the
form a layer.

The fryer is moved in the direction of arrow 141, e.g.
It rotates at a speed of 2000 revolutions per minute. Spool 14
2 is in the direction of arrow 143, that is, in the same direction as the direction of rotation of the fryer, but for example, 2118 times per minute.
rotate at the speed of rotation. This spool therefore additionally pulls the line running through the deflection rolls or the guide means attached to the flyer in its direction of travel. This defines the winding pitch (twist length) of the winding on the spool. The rotational speed of spool 142 is additionally controlled to provide rope winding speeds that are compatible with increasingly full spools.

FIG. 12 is a top view of the device corresponding to FIG. 11. However, in the case of Fig. 12, there are six spools 160, 161, 162, 163, 164, 16.
5 are provided, and the wire bundles are pulled out from these spools, untwisted, and guided to a perforated disk 138. One of these six spools is the one around which the core wire is wound. The method of the present invention is effective and economical for drawing wire from a spool on which the wire is initially wound with a twist. That is,
In addition to removing the initial twist by pulling the line axially past the end of the spool, the present invention rotates the flyer around this reel while keeping the spool stationary, and the flyer is Since the mass is always the same, it is easy to control the rotational speed of the fryer even if many wires are wound around the spool and the weight increases. Therefore, the winding layer should always be wound in a uniform layer without creating peaks or valleys. Also, when drawing out the line, the line can be easily drawn out without providing any braking means for the spool.
