BACKGROUND OF THE INVENTION
The present invention relates to a stranded wire machine used for manufacturing a stranded wire product such as a steel cord, a rope, and an electric wire.
[0002]
[Prior art]
A conventional stranded wire machine used in the production of a stranded wire product such as a steel cord, a rope, and an electric wire is a tubular type disclosed in Japanese Patent Laid-Open No. 59-9293. In-out or out-in buncher type shown in JP-A-69686, JP-A-58-41989 or JP-A-58-23526, etc., and a large-scale planetary type are generally used. It is.
[0003]
[Problems to be solved by the invention]
However, each of the above conventional twisting machines has a complicated mechanism using a cradle or the like, resulting in high equipment costs and a large floor area for installation.
[0004]
In addition, since all of the above conventional stranding machines are to draw and rotate the wire body around a reel or bobbin for a long distance, a guide or the like for preventing swelling due to centrifugal force is necessary. Not only does it become a complicated mechanism, but also there is a problem that the air resistance due to rotation of these guides etc. is large and the power loss becomes very large, and also because the striatum is rubbed with guides etc. with a large centrifugal force There was an adverse effect on the surface of the striatum and there was a problem that the product quality was lowered.
[0005]
Furthermore, in tubular type, planetary type and in / out type bunchers, the number of twists cannot be greater than the machine specification. Conversely, if the number of twists is less than the machine specification, there is an unused cradle part. Even if it exists, there exists a problem that the waste of energy will become large by rotating the tube and flyer of the same magnitude | size, and power loss will further increase.
[0006]
The present invention solves these problems, simplifies the mechanism of the stranding machine, reduces facility costs (cost reduction) and floor space (space saving), and reduces power loss (power saving) and It is intended to improve product quality (high quality).
[0007]
[Means for Solving the Problems]
Since the present invention is to solve the above problems, as described in claim 1, and a rotary shaft having two or more striatum passage hole parallel to the axis allowed to pass through the striatum, the rotation on the rotating axis One paying reel mounted freely, brake means for braking the rotation of the paying reel on the rotating shaft, and one or two rotating integrally with the rotating shaft radially outward near the outer periphery of the paying reel The above-described flyer and the guide means that is introduced from one end of the wire rod passage hole and led out from the other wire wire so that the wire rods are not entangled with each other constitute a stranded wire machine, Two or more wire rods equal to or less than the number of flyers are led through the flyer to the shaft passage hole of the rotating shaft, and the rotating shaft is driven to rotate, thereby guiding the wires through the fryer. Or between From the axial direction of the Luo striatum and the rotary shaft is obtained by such twisting and other striatal that led to the striatum passage hole.
[0008]
This stranding machine does not rotate the wire body to be twisted around the feeding reel for a long distance, but draws it from the feeding reel through a minimum distance through the flyer and passes almost the axis of the rotating shaft. Centrifugal force is hardly applied to the striatum, and therefore a guide or the like for preventing swelling due to centrifugal force is unnecessary. In addition, since a cradle or the like is not required, the structure is simple, compact and equipment cost is low, and the floor area for installation is small.
[0009]
And the air resistance by the guide etc. for preventing the swelling of the filamentous body by centrifugal force is lost, the power loss is reduced, and the bad influence on the surface of the filamentous body by rubbing the filamentous body with the guide etc. Loss and improve product quality.

It is preferable that a guide roller is provided, and a guide hole is provided in the vicinity of the other end of the linear body passage hole so as to lead out the linear bodies that have passed through the linear body passage hole without being entangled with each other. By doing so, the striate bodies from the flyer can be passed through the striate body passage holes of the rotating body so as not to get entangled with each other.
[0013]
According to a fifth aspect of the present invention, the twisting machine generates a braking force as a brake means by being interposed between the rotating shaft and the feeding reel on one end side of the portion that supports the feeding reel of the rotating shaft. It is preferable that a friction plate is provided and a brake adjustment mechanism that adjusts the braking force by the friction plate is provided on the other end side, so that the tension is applied to the rotating shaft in an appropriate tension state. The reel can be rotated as fast as the length necessary for twisting the filaments so that the filaments can be smoothly fed out and twisted together.
[0014]

In order to prevent free rotation with respect to the reel shaft 7, the reel shaft 7 is fixed to the flange portion 7 a with a knock pin 9 and fixed in the axial direction by an annular screw 10 screwed to the outer periphery of the front end portion of the reel shaft 7. ing.
[0020]
A friction plate 11 is inserted between the flange portion 1 c of the rotary shaft 1 and the flange portion 7 a of the reel shaft 7 as a brake means for braking the rotation of the supply reel 8 (reel shaft 7) on the rotary shaft 1. ing. An annular screw 12 that is screwed onto the outer periphery of the rotating shaft 1 is provided on the outer peripheral portion of the shaft main body 1 a of the rotating shaft 1, and the reel shaft 7 is axially disposed with respect to the annular screw 12. There is provided a brake adjusting mechanism including a spring 13 that acts to press the flange portion 7a of the reel shaft 7 against the flange portion 1c of the rotating shaft 1 through the friction plate 11 by urging in the separating direction.
[0021]
Further, the flange portion 1c of the rotary shaft 1 includes two flyers 14a, so as to rotate integrally with the rotary shaft 1 at a symmetrical position around the rotary shaft 1 in the radial direction near the outer periphery of the feeding reel 8. 14b is attached. One or two or more flyers are provided in consideration of the number of filaments that are fed out simultaneously. In the example shown in the figure, two flyers 14a and 14b are mounted at the target position in consideration of the rotational balance in the case of two simultaneous feeding.
[0022]
The flyers 14a and 14b are parallel to the passage surface along the passage of the filaments so as to guide the filaments fed from the delivery reel 8 to the filament passage holes 5 and 6 of the rotary shaft 1. A pair of guide rollers 16a, 17a and 16b, 17b is attached to each.
[0023]
In the illustrated example, two linear bodies 15 a and 15 b are wound around the supply reel 8.
Then, the two linear members 15a and 15b wound around the supply reel 8 are distributed to two flyers 14a and 14b, respectively, through the guide rollers 16a and 17a or the guide rollers 16b and 17b, respectively. One is guided to each of the two striate passage holes 5 and 6.
[0024]
The linear bodies 15a and 15b pass through the linear body passage holes 5 and 6 of the rotary shaft 1, and in that case, the linear bodies 15a and 15b are smoothly guided to the linear body passage holes 5 and 6, As guide means for passing through the striate passage holes 5 and 6 so as not to be entangled with each other, in the vicinity of the rear of the flange portion 1c where one end of the striate passage holes 5 and 6 of the rotating shaft 1 is located, Guide rollers 18a and 18b are provided so as to guide the filaments 15a and 15b led from the fryer 14a and 14b to the filament passage holes, and in the vicinity of the other ends of the filament passage holes 5 and 6 Guide holes 19a and 19b are provided to guide the bodies 15a and 15b without being entangled with each other.
[0025]
A plate 21 having a through hole 20 in the shaft core is integrally connected to the tip of the rotary shaft 1, and the guide holes 19 a and 19 b are formed on the outer periphery of the rear end of the plate 21.
[0026]
As shown in FIG. 1, the twisting machine has a collecting die 22 installed in front of the axis of the rotary shaft 1, and a guide roller 23 and a winding roller 24 installed in front of the collecting die 22. Then, the two linear bodies 15a and 15b led out from the linear body passage holes 5 and 6 of the rotating shaft 1 are guided to the collecting die 22 through the eye plate 21 rotating integrally with the rotating shaft 1, As the plate 21 rotates, it is twisted together by a collecting die 22 and wound as a stranded wire 25 by a take-up reel.
[0027]
In this way, a single stranding machine (single stranding machine) is used, and the two filaments 15a and 15b wound around the feeding reel 8 are rotated through the guide rollers 16a and 17a and the guide rollers 16a and 17b and 16b and 17b of the fryer 14a and 14b. A so-called 1 × 2 stranded wire having no core wire is obtained by guiding the wire 1 to the striate-passing holes 5 and 6 of the shaft 1 and guiding and twisting the assembly die 22 through the eye plate 21.
[0028]
In the illustrated example, two flyers 14a and 14b are attached to the rotating shaft 1. However, as described above, the number of flyers may be one or two or more. The configuration of the wire rod passage holes and the like can be appropriately changed. For example, four flyers can be used to obtain a stranded wire having a so-called 1 × 4 structure without a core wire.
[0029]
Moreover, even when using one single strand wire machine, two wires are twisted around one by inserting one wire body from the rear outside into the shaft core hole 4 of the rotating shaft 1 as a core. In addition, a so-called 1 + 2 stranded wire can be obtained, and a so-called 1 + 4 stranded wire in which four wires are twisted around one can be obtained.
[0030]
Moreover, this twisting machine can also arrange | position a single unit twisting machine in series, and can make it perform a multiple strand.
[0031]
FIG. 2 shows an example of a mode in which two stranding machines shown in FIG. 1 are arranged in series. In this example, two stranding machines (single stranding machines) indicated by A and B in FIG. 2 are arranged before and after the rotating shafts 1 and 1 in a line, and each single stranding machine A and B are respectively supported on bearings 2 and 2 by rotating shafts 1 and 1 respectively, and are installed on tables 31 and 31 so as to be rotatable around rotation fulcrums 32 and 32, respectively, via pulleys 3 and 3, respectively. Belt driven by a separate motor (not shown). The detailed structure of each of the stranded wire machines A and B of A and B is as described above with reference to FIG. Here, the overlapping description of the structure is omitted. In FIG. 2, the same reference numerals as those in FIG.
[0032]
In FIG. 2, two single stranding machines A and B each have two flyers 14a and 14b attached to the rotary shafts 1 and 1 in a substantially symmetrical arrangement, and the front and rear twisting machines A and The individual motors are tuned and rotated by the inverter so that a phase difference of 90 ° is generated at the position of the flyers 14a and 14b between the two.
[0033]
The eye plate 21 is connected to the tip of the rotary shaft 1 in the single strand wire machine A arranged in the front.
A collecting die 22 is installed in front of the eye plate 21.
[0034]
The rear single strand wire machine B is provided with the eye plate 21 removed, and further, a lead feeding roller 33 for the core is installed at the rear.
[0035]
In this example, as shown in FIG. 2, two wire bodies 15a, 15b; 15c, 15d (not shown) are wound around the reels 8, 8 of the two single strand wire machines A, B, respectively. For example, one (or a plurality of) filaments 15e may be wound around the lead feeding roller 33. And the two linear bodies 15a and 15b wound around each supply reel 8 and 8 of the front single strand wire machine A are the rotating shaft 1 through the guide rollers 16a and 17a; 16b and 17b of the fryer 14a and 14b. The two filaments 15c and 15d, which are guided to the filament passage holes 5 and 6 (not shown) and wound around the respective reels 8 and 8 of the rear single strand wire machine B, are connected to the flyer 14a, 14b (not shown) is guided to a linear body passage (not shown) of the rotating shaft 1 through a guide roller (not shown), and the linear body 15e wound around the last feeding roller 33 is a core. Are inserted into the shaft core hole (not shown) of the rotary shaft 1 of the front single strand wire machine A through the shaft core hole (not shown) of the rotary shaft 1 of the rear single strand wire machine B. Then, when the rotary shafts 1 and 1 of the front and rear single stranding machines A and B are driven to rotate, the shaft core hole 4 of the rotary shaft 1 is rearward around the linear body 15e inserted from the rear as the core. By inserting one filament from the outside as a core, the four filaments 15a, 15b, 15c, and 15d are twisted together to form a so-called 1 + 4 strand.
[0036]
Note that the number of the filaments 15e to be inserted from the rear may be plural as described above. In this case, the number of the filaments 15e is n, and a stranded wire having an n + 4 configuration can be formed.
[0037]
In addition, the number of fryer attached to the rotary shafts 1 and 1 of each single strand wire machine A and B may be one or two or more. By using four, a stranded wire having a 1 + 8 structure can be obtained.
[0038]
Further, without using the lead feeding roller 33, only the four wire bodies 15a, 15b, 15c, 15d wound around the feeding reels 8, 8 of the front and rear single stranding machines A, B are twisted. In this case, a stranded wire having a 1 × 4 structure without a core wire can be obtained.
[0039]
Thus, it can twist to 1x2-1x4 structure and n + 1-n + 4 structure by the serial arrangement of two single strand wire machines.
[0040]
Further, by increasing the number of directly connected single stranding machines, it is possible to twist more.
[0041]
In the two-unit serial arrangement shown in FIG. 2, when the reels 8 and 8 of the single strand wire machines A and B are exchanged, for example, as shown in FIG. , 8 are rotated by approximately 90 °, the delivery reel 8 of the front single strand wire machine A is stopped at a position where it can be taken out without hitting the collective die 22, and the feed reel 8 of the rear single strand wire machine B is It stops at the position where it can be taken out without hitting the rear part of the stranded wire machine A. Then, after the delivery reels 8 and 8 are removed and new delivery reels 8 and 8 are mounted, the delivery reels 8 and 8 are rotated around the rotation fulcrums 32 and 32 to return to the original installation positions. In this way, the reel can be easily replaced.
[0042]
In the example of FIG. 2, the individual motors are rotated in a synchronized manner by an inverter as described above, thereby enabling multiple strands by the twisting machines arranged in series. In the case of arranging a plurality of single strand wire machines supported by individual bearings 2 and 2 in series, as a tuning method for each single strand wire machine, there is one electric motor, thereby one drive line. A single drive line shaft is used to drive each single twisted wire machine with a belt, or a single motor is used to drive a single belt. The wire machine can be rotated in a synchronized manner by connecting the rotating shafts with a coupling after setting the filaments on the respective reels.
[0043]
As another example of arranging a plurality of single stranding machines in series, as shown in FIG. 4, the main bodies of the two stranding machines A and B are symmetric with respect to each other with one bearing 2 interposed therebetween. It is also possible to arrange. In this case, the equipment becomes compact by using a common bearing.
[0044]
【The invention's effect】
As is clear from the above description, according to the present invention, the strands to be twisted have a short distance to be drawn around the reel, and most of them pass through the axis of the rotating shaft, so that the centrifugal Because there is almost no force, a guide to prevent swelling due to centrifugal force is unnecessary, and a cradle is also unnecessary, so the structure is simple, compact, and the equipment cost is low, The floor space for installation is also small.
[0045]
In addition, since a guide or the like for preventing the swell of the striated body due to centrifugal force is not required, the air resistance can be reduced, power loss can be reduced, and the striated wire is rubbed with the guide or the like. The adverse effect on the body surface is eliminated, and the product quality can be improved.
[0046]
Further, by arranging a plurality of single strand wire machines in series, multiple strands can be made and the number of twists can be freely changed. And the number of coupling | bonding can be adjusted according to the number of twists, and when there are few twists, by reducing the number of couple | bonding, the components to be rotated unnecessarily can be eliminated and the waste of energy can be reduced.
[0047]
In this way, cost reduction and space saving due to simplification of the mechanism of the stranding machine, power saving and high quality can be realized at the same time.
