Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to linear objects such as single wires, multiplex wires, cables, ropes, cables, glass fibers, etc. (hereinafter simply referred to as wires for simplicity of explanation). ) from its scroll, spool, etc. 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 then deflected by rollers so that the wire is placed tangentially onto the spool core. . At this time, 1 of the fryer
The line receives approximately 3600 screws 9 per revolution.

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 is again in motion.

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 process must be interrupted each time all of the wire wound on a spool is pulled out and the spool is empty. First, the end of the line on the empty spool must be joined to the start of the line on the next spool. To avoid this joining operation and the associated losses, a very large spool would be required, capable of winding very long lines. Naturally, a spool wound with such a long wire is extremely heavy and difficult to handle.

Moreover, since the spool rotates when drawing out the line, special braking means must be provided for the spunil in order to maintain a constant load on the line during drawing out.

The inconvenience of winding the line onto the spool and pulling the line out from the spool is such that the line can be wound onto the spool using a flyer and/or unwound from the spool, or for further processing. This can be avoided by drawing lines in an overhead manner. because,
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, when laying cables, for example, underground cables that have been wound on spools must be pulled out from the spools using flyers or overhead from cable coils, problems similar to those described above arise. Indeed, due to their twisting, such cables tend to form tortuous serpentine lines during installation, which is undesirable. Detailed view 3rd and 10th
The proposal disclosed in No. 2,101 does not straighten the twist of the cable so that the cable can be laid in a straight line, but it is drawn out to a straightening device that straightens the meandering line-shaped bend caused by the twist. The next line will be guided.

The above-mentioned twisting problem can occur when multiple wires, e.g. four wires, are simultaneously pulled from each spool by one flyer, and after the wires are pulled out to fit together, e.g., an electrical cable button. This is particularly noticeable when attempting to insulate with enamel coating.

In this case, it is necessary to separate the wires from each other after they are drawn from each spool, and it is impossible to separate the wires if they are already in a "hanging" state at the time of drawing. becomes.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a method by which a 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, it has been found that if M is pulled overhead from the roll of wire according to the claimed policy, the wire will be pulled from the spool or coil without twisting.

For example, when a line is pulled out from the outer loop overhead, the line is pulled out in the same direction as the original line introduction direction. If the line is drawn out in the direction of the extension of the original direction of introduction, the twist will 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 on the wire can be released by pulling the wire out in the direction of the extension of the introduction direction. be done.

For technical reasons, a spool with a conical winding core is
When winding, it is often convenient to mount the wire vertically with the larger core diameter facing upwards, and then wind the wire around the core using a flyer. 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, the wire is pulled out through the inside of the coil and then turned downward and guided, thereby unscrewing the wire and untwisting the wire. The wire therefore exits the coil without twisting.

In order to expose 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 in order to draw out the wire.

Extracting the wire in this manner with an overherd is particularly advantageous in tube-type or cage-type wire alignment devices. Multiple wire-wound coils, or multiple spools with wire wound around them, are arranged one behind the other when viewed from the alignment direction, and the multiple wires drawn out from these coils or spools gather at the alignment point. You will be guided as follows. In such a device, the invention allows all spools to be arranged stationary and fixed. However, unlike the prior art, there is no need to move a large mass during twisting. The drawing direction of the wire may be parallel to the rotation axis of the alignment device.

Furthermore, the drawing direction may be a direction perpendicular to the rotation axis of the folding device or an oblique direction forming a certain angle with respect to the folding direction. Conventionally, such devices required expensive braking devices for side-bent rotating spools; however, 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 wood-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 bending of the wire 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 do not intertwine neatly with each other,
The electrical quality of the strand is adversely affected throughout its length.

Furthermore, such irregularly twisted wires increase the cost of the insulating material. Absolutely? ! Because the material is obtained from crude oil, twisted wires, if twisted, 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 invention is intended to achieve this objective as follows. That is, a plurality of wires required for one layer or at least a portion of the plurality of wires necessary for one layer are wound onto a single spool with a screw thread, and when the wires are assembled, the plurality of wires are wound from the spool. The wire is pulled out in such a way that the wire is untwisted and fitted into the rope. According to this method, there will be no difference in running speed between the lines even if the alignment is performed at a very high speed using a fryer, for example. For example, the stranded spool (fryer) can be rotated at a high speed of 2,000 revolutions per minute. For example, about 100 to 1
It is sufficient to rotate at a speed 50 rotations higher.

The features and detailed structure of the present invention will be understood from the claims, the drawings, and the detailed description based on the drawings.

Hereinafter, the present invention will be described in detail with reference to the drawings.

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

The wire 4 coming from the direction of the arrow is wound around the winding core 5 of the spool 6 by the flyer 2 rotating around the axes A and -h. For this purpose line 4 is the deflection roller 7.8.9
The wire is guided in such a way that it lies tangentially on the spool core 5. The flyer 2 moves up and down in the direction of the arrow 10 so as to wind this line one station between the flanges 11 and 12 of the spool.

A roller 8 pivoting in the direction of arrow 1 about axis A-A
and 9, the wire 4 is subjected to twisting in the direction of the arrow 13. By this twisting, the wire is sequentially placed one layer at a time on the spool 60-wound core 5.

Once wound onto a spool, the wire 4 is pulled out of the outer layer in the direction of arrow 20, as shown in FIG. This is not necessarily desirable for subsequent machining operations.

When the wire 4 is pulled out from the outside in the direction indicated by the dashed line 21, the wire 4 undergoes a further twist, 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 6.

However, when the wire is pulled from the spool from the outside in the direction of arrow 2B, the winding twist shown by arrow 13 is superimposed on the unwinding twist shown by arrow 24. Both twists cancel each other out.

Therefore, the country 4 leaves the spool 6 in the direction of the arrow 23 without twisting.

In this case, the direction 21 of the gland's exit must be opposite to the direction 6 of its introduction.

The withdrawal of the line from the spool is similar to a specially constructed withdrawal device, such as a flyer constructed such that it can pivot in the opposite direction to the flyer 2 of FIG. 1 and guide the line in any suitable direction. It can also be carried out using a roller system.

It has proven advantageous to use the spool shown in FIG. In the case of this spool, some winding core 30
is made in 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 62 is formed into a sharp shape. Therefore, when drawing out the wire 63, the wire 63 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 drawn over the lip of the spool flange 32 so that the lip 64 of the spool flange 32 is shaped into a draw ring.

The lower spool flange 65 forms an obtuse angle with the winding core 6D, so the wire can be easily pulled out from this corner 66 as well.

The spool in Figure 26 can be very large, so
The weight of the spool when wound with wire becomes extremely large. Therefore, for transportation, the spool is moved to the roller 37,
38.39 may be transported.

Figure 4 shows a winding core 4 shaped into a conical shape with a large slope.
The spool 40 with 2 is shown. In the case of this spool too, the winding layers 45, 46 are laid out 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 6 using the flyer 2 shown in FIG.

When this line is pulled out in the direction of arrow 48 for the next machining operation, the line will retain its twist. Rollers 49, 50, 51 pivoting in the direction of arrow 14
When the wire is withdrawn using the wire, 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, so as to form a conical winding layer on the spool 52 from the direction of introduction direction 6, but with the twisted spool orientation shown in FIG. In other words, the spool is installed and wound so that the larger diameter side of the core is on the lower side. In order to draw out the line, this spool is turned upside down and is in the state shown in FIG. That is, in the state of the line drawing pot shown 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 has been removed in order to draw out the + gland. Furthermore, in the case of this configuration, the winding core 56 is also pulled out from the spool 52 in the direction of the arrow 54, or the winding core 56 is pulled out from the spool 52 in the direction of the arrow 54 by using the fold 55. Wire winding layer 5
6 by a distance sufficient to create a space 57 between them. Starting from the inner end 58, the wire is led 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 5, so that the wire leaves in an untwisted state.

Reversing the top and bottom of a heavy spool wrapped with line is a bloody and grueling process, and you will often want to avoid this. In this case, the lines are shown in Figure 5.
In other words, the spool can be directly attached to the spool with the large diameter side of the core facing upward. In order to draw the wire out from inside the coil without twisting, it is therefore necessary to pull the wire downward through the narrow opening of the coil. but.

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 pushed downwards together. One way to deal with this is shown in FIG.

That is, the wire on the spool, in a position similar to that in FIG. It exits the coil in the direction of 171. In this way, the wire can be drawn out from the spool in an untwisted state without any problems.

When the wire is pulled out using the method shown in FIGS. 5 and 14, the upper wire winding layer 60 is Board 61
weighted by.

In this configuration, the end 62 of the line remains stationary during the drawing process. Therefore, the starting end 66 of the line on the next spool can be joined to its terminal end 62 at position 64 while the cutting operation is in progress. Therefore, it is no longer necessary to idle the machining operation each time the spool is empty.

Figure 26 shows coils 65 and 66 of wire wound around two juxtaposed conical cores.

The wire starting end 67 of the innermost coil 65 after winding is completed
The wire is drawn out from the coil 65 for the next processing operation. The wire end 68 of this coil 65 is connected to the wire start end 69 of another coil 66, as described above with respect to FIG. coil 6
A line is drawn from 6. Of course, it is possible to arrange further coils one after another after the coil 66, and the end and start ends of these wires are sequentially and pre-done.
Yoshiai can be kept.

The off-line view is a sectional view showing the tube type aligning device. Axis B
-A coil 71.
72 and many more coils not shown are arranged in sequence. 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 grooved when the wire is wound around the winding core, that is, in a direction that eliminates twisting when the wire is drawn out. Lines 73, 74 guide giant 7' 5, 76,
You will be guided through 77. These lines therefore rotate with the rotation of tube 70. The wires then pass through a rotatable perforator 78 to the twisting point 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 is transferred to the deflection roll so, s1. It can be guided to the spool 86 via s2. This spool 86
is rotatable about axis D--D, and the twisted wire or pile is wound onto the core 84 of the spool. The deflection roll 82 can be reciprocated in the direction of arrow 85, and can also be reciprocated 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 86, a flyer winding device as shown in FIG. 1 can also be used in this case. In such a case, when the wire is fed out for further processing, the wire is pulled out from the spool in an untwisted state, and the coiled wire is subjected to an additional twist. You need to make withdrawals to avoid this.

FIG. 28 is a sectional view showing a cage type twisting device.

The operation of this device is basically the same as the tube type alignment device shown in FIG. 7 above. The interconnected cages 86, 87, 88 rotate about the axis ()-G.

The wire-wound coils 90, 91, 92 in each cage are stationary. That is, it is installed so that it does not rotate together with the cage.

In the embodiment of FIG. 28, the wire is wound onto a spool of construction as shown in FIG. , the wire is drawn out in the direction of untwisting.A guide roller 593.94 is subordinate to each coil.One roller of each set of these rollers is pulled out with the required tension at the twisting point. The brakes are applied so that the lines come together.

As understood from FIG. 28, each coil 90, 91, 92 in this twisting device can be arranged facing in any direction. To illustrate the various possible coil arrangements, in Figure 28 coil 90 is arranged with its coil axis H-H oriented perpendicular to coil axis G-G, and coil 91 . is arranged so that its axis J-J is fixed at a certain angle with respect to the coil axis G-G, and the coil 92 is arranged such that its axis -K is coaxial with the coil axis G-(),
It is arranged so that All of these arrangements are examples of coil arrangement directions. The shuffling process is the same as for the tubular shuffling device shown in the off-figure.

In the embodiments shown in FIGS. 9 and 10, a wire bundle 102 consisting of four wires 111, 112, 113 degrees 114 is wound around one spool 100 in advance using a flyer. This wire bundle 102 is twisted so that four strands form one sile-like rope. Spool 1
The wire bundle 102 is untwisted by the flyer rollers 103, 103' which rotate in the direction of the arrow 115 in the direction of the arrow 115, and each wire of the wire bundle is pulled out from the spool so that each wire exits the deflection roller 104 as strands 111 to 114. . A deflecting roller 106 is assigned to each strand, which in each case guides the strand towards an enameling device 105, for example. The strands exiting the enamel coating device are passed through deflection rollers 107 into one row 5108.
You will be guided to. This common roller 108 further guides the four wires as a parallel wire bundle.

These lines are again "wound" and wound onto one spool 120 by flyer 109 pivoting about axis K--K in the direction of arrow 116.

According to the prior art, this method was carried out by winding a plurality of strands of the wire bundle onto a spool 100 in parallel and adjacent rows. The spool 100 is rotatably mounted around the axis A-A, and the spool 100 is rotatably mounted on the spool 100.
° was fixed. These fixed rollers 103. -10
The wire bundle is unwound from the rotating spool via the roller 61 and guided to a roller 104, and after the wire bundle has passed through the roller 104, the individual wires are separated.

In the embodiment shown in FIG. 11, the core wire is drawn from a spool 160 and guided via rollers 134 and 137 to a perforated platen 138 where it is further confined through a hole in the middle of the perforated platen to a fryer 140. Ru.

A wire bundle consisting of, for example, six strands is pulled out from the spool 131. This wire bundle is wound onto a spool 161 using a flyer, for example, in the manner shown in FIG. 1, so that the wire bundle rests on itself. The wire bundle on the spool 161 is pulled out so that the wires are untwisted.

Therefore, after passing through the rollers 165 and 167, each strand can enter the hole 151 of the hole rh hole 168 in a separated state. These holes 15 as shown in FIG.
1. It is arranged concentrically with the hole 150 for the d core wire.

A wire bundle consisting of, for example, 12 strands can be pulled out from the sprue 162. Similarly to the above, the wire bundle is also twisted when winding the spool. In this case as well, the wire bundle is untwisted after passing through the fan rollers 166 and 137, and these strands pass through the corresponding hole 152 which is arranged concentrically with the hole 151 of the perforated plate. Selected to be guided through. The strands of wire that have been guided to the flyer 140 in this way are twisted when the flyer turns and are passed from the spool 161 to the hole 151.
The six strands guided through form a first layer around the core wire, and the twelve strands guided through hole 152 from spool 162 form a second layer. do.

The fryer moves in the direction of arrow 141, for example 2 times per minute.
It rotates at a speed of 000 revolutions.

The spool 142 moves in the direction of arrow 146, i.e. in the same direction as the direction of rotation of the fryer, but for example
Rotates at a speed of 18 revolutions. Therefore, this spool additionally pulls the running line in its running direction via a guide means attached to the shoulder roll or fryer, thereby determining the winding pitch length of the frame line on the spool. The rotational speed of the 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, six spools 1 (SQ, 1
61, 162, 163, 164, and 165 are provided, and the wire bundles are pulled out from these spools, untwisted, and guided to the perforated disc 16B. One of these six spools is the one around which the core wire is wound.
