Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a single wire for electric wires, a twisted wire,
The present invention relates to a wire rod feeding device that feeds out various wire rods such as an optical fiber, a twisted yarn for spinning, a tape, a strip, and a tube toward a wire rod processing equipment such as insulation, protective coating, and surface treatment.

[0002]

2. Description of the Related Art Conventionally, an apparatus having a structure shown in FIG. 5 is generally used as a wire rod feeding device for feeding the wire rod toward a wire rod processing equipment. This device uses wire W
And a circular wire guide member 2 arranged coaxially with the winding frame 1 adjacent to one side of the winding frame 1 in the axial direction.

The reel 1 is a vertical stand 3 of a reel supporting carriage 3.
It is fixedly supported by a support shaft 4 projecting laterally from A. The wire rod guide member 2 is formed by forming a wire rod contact edge portion 2B obtained by inclining the outer peripheral edge of a plate-shaped or frame-shaped circular flange member 2A toward the winding frame 1 by a predetermined angle. The wire rod guide member 2 has a circular flange 2A whose center portion is fixed to a drive shaft 5 of a drive mechanism (not shown) including a motor, a speed reducer, etc. built in the support shaft 4. The wire rod guide member 2 is rotationally driven at a substantially constant speed around the central axis of the winding frame 1 in a direction in which the wire rod W is pulled out from the winding frame 1 via a drive shaft 5 to which power is transmitted by the drive source. The wire W drawn out from the winding frame 1 is guided in such a manner that the wire W is smoothly fed in the axial direction while turning in the circumferential direction of the winding frame 1. Reference numeral 6 denotes a fixture for the wire rod guide member 2 screwed to the tip of the drive shaft 5 so that the wire rod guide member 2 does not come off the drive shaft 5. Further, a cone-shaped hood 7 having a hood outlet hole 7A in the front part is arranged in front of the wire rod W of the wire rod guide member 2 being fed out, and is held by a support base 3B of the reel support car 3.

The wire W is wound in the circumferential direction of the bobbin 1 by a pulling force from a wire rod processing equipment (not shown), and the bobbin 1 is rotated.
And is drawn out in the axial direction of the reel 1 while coming into contact with the wire rod contact edge portion 2B of the wire rod guide member 2 which is driven to rotate around the central axis of the reel 1. And hood 7
It passes through the inside and is fed out from the hood outlet hole 7A toward the wire rod processing equipment (not shown).

[0005]

It is desirable that the wire rod W fed from the wire rod feeding device toward the wire rod processing equipment be fed out with a preset feeding tension, but the operating state of the wire rod processing equipment is midway. Alternatively, the take-up tension of the wire W, that is, the payout tension of the wire W may fluctuate. When the feeding tension of the wire rod W gently changes, for example, when the tension gently increases, the wire rod guide member 2 swivels in the direction in which the wire rod W is pulled out from the winding frame 1.
Since the turning speed of the wire rod increases and the feeding speed of the wire rod W increases, the feeding tension of the wire rod decreases and returns to the original set tension. On the contrary, when the feeding tension of the wire W is gradually reduced, the turning speed of the wire guide member 2 that turns in the direction in which the wire W is drawn from the winding frame 1 is decreased, and the feeding speed of the wire W is decreased. , The feeding tension of the wire increases and returns to the original set tension.

Even when the wire rod guide member 2 is constructed so as to be able to rotate freely around the central axis of the reel 1 in the direction in which the wire rod W is drawn out from the reel 1, the increased or decreased wire rod W is likewise obtained. It is possible to return the feeding tension of No. 1 to the original set tension. Further, even when the wire rod guide member 2 does not rotate around the central axis of the winding frame 1 and is of a fixed type, the wire rod W has the wire rod contact edge portion 2B of the wire rod guide member 2.
It is possible to increase or decrease the amount of slip (slip amount) in which the wire W comes in contact with and to return the feeding tension of the wire W to the original set tension.

However, when the payout tension of the wire rod W changes abruptly, that is, when it suddenly increases or decreases, regardless of whether the wire rod guide member 2 is forcedly rotated, free-rotated or fixed, It is difficult to control the feeding tension of W to return it to the original set tension. For this reason,
When the payout tension of the wire W increases particularly rapidly, the wire W is stretched, causing constriction and disconnection, and the wire W
There was a problem that it was difficult to get out. On the other hand, when the payout tension of the wire W is particularly sharply reduced, the wire W causes a kink, and when the wire is a twisted wire or twisted yarn, twisting disorder or the like is caused, and thus the wire is processed and treated. There was a problem that caused product defects and quality deterioration.

The present invention has been made in view of the above, and no matter how the feeding tension of the wire fluctuates suddenly, the fluctuation of the tension is quickly absorbed and returned to the original set tension, and the constriction of the wire is An object of the present invention is to provide a wire rod feeding device capable of preventing wire breakage, kinks, twisted twists, etc. to improve the operating rate of equipment and the yield of products and to manufacture good quality products.

[0009]

In order to achieve the above object, the invention described in claim 1 of the present invention is a winding frame in which a wire is wound and housed, and one side in the axial direction of the winding frame. A wire rod feeding device provided with adjacent wire rods, which guides the wire rods so that the wire rods drawn from the winding frame are fed in the axial direction while turning in the circumferential direction of the winding frame. It further comprises a damper member for displacing the member in the axial direction of the winding frame according to the tension fluctuation of the wire rod to absorb the tension fluctuation of the wire rod.

With such a structure, even if the feeding tension of the wire drawn out from the winding frame and turned around in the circumferential direction of the winding frame is gradually changed, the wire guide member changes the tension. Accordingly, the winding frame is quickly displaced in the axial direction, and the feeding tension of the wire can be quickly absorbed. Therefore, the tension fluctuation of the wire is quickly returned to the original set tension, and the wire is narrowed, broken, kink,
It is possible to prevent twisting disorder and improve the operating rate of equipment and the yield of products, and to manufacture good quality products.

According to a second aspect of the present invention, in the invention according to the first aspect, the damper member is a spring member for urging the wire guide member toward the winding frame, It is arranged on the side opposite to the winding frame with respect to the guide member and is arranged coaxially with the winding frame and the wire rod guide member. If the damper member is composed of a spring member in this way, the response to the tension fluctuation of the wire rod
Therefore, even if the feeding speed of the wire increases, it is possible to quickly absorb the change in tension, and the productivity of the product can be improved. Further, since the damper member is lightweight and compact, it does not take up a space for its installation, and its installation is easy, which simplifies the structure of the feeding device.
The price of the device can be reduced. Furthermore, the spring length associated with the displacement of the wire rod guide member can be adjusted by changing the initially set length of the spring member so as to be adapted to the wire rod size, the feeding tension, the speed, etc., and the wire rod feeding workability is improved. The effect that can be obtained is obtained.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION One embodiment of the present invention is shown in FIG.
2 will be described in more detail. 1 is a front view thereof, and FIG. 2 is an enlarged cross-sectional view showing an arrangement state of a damper member which is a main part of the feeding device of FIG. It should be noted that parts having the same configurations as those of the conventional wire feeding device are designated by the same reference numerals. The wire rod feeding device of this embodiment has a winding frame 1 in which the wire rod W is wound and housed, and a circular shape which is arranged adjacent to one side in the axial direction of the winding frame 1 and coaxially with the winding frame 1. The wire rod guide member 2 and the damper member 8 for displacing the wire rod guide member 2 in the axial direction of the winding frame 1 along with the tension change of the wire rod W to absorb the tension change of the wire rod W are provided.

The reel 1 comprises a bobbin, a drum, a reel, a spool, a stem, a core shaft and the like having a collar body with or without a collar plate. A winding frame 1 shown in FIG. 1 is a cylindrical winding cylinder (not shown) and disc-shaped collar plates 1 provided on both sides thereof.
It is composed of a drum composed of A and 1B. This reel 1
Is fixedly supported on a support shaft 4 projecting laterally from a vertical stand 3A of the reel support cart 3. Although not shown, the support shaft 4 is provided so as to be able to move up and down along the vertical stand 3A so that the winding frame 1 can be easily attached to and detached from the wire rod feeding device.

The wire rod guide member 2 is formed, for example, by forming a wire rod contact edge portion 2B in which an outer peripheral edge of a plate-like or frame-like circular flange member 2A is inclined toward the winding frame 1 side by a predetermined angle. Although not shown, a tube rod ring may be attached to the outer periphery of the wire rod contact edge portion 2B. It is preferable to provide the tube rod ring as described above because it is possible to surely prevent the outer surface of the wire W from being rubbed by friction and being scratched when the wire W is fed while slidingly contacting the ring. . Circular flange body 2A of this wire rod guide member 2
A plain bearing 9 is mounted in the center hole 2C of the above. This wire rod guide member 2 is fitted along the mounting shaft 10 by fitting its slide bearing 9 onto the outer periphery of a mounting shaft 10 mounted coaxially with the winding frame 1 on the front flange plate 1A side of the winding frame 1. The winding frame 1 can be displaced in the axial direction. Further, it becomes possible to freely rotate around the central axis of the winding frame 1 in the direction in which the wire W is drawn out from the winding frame 1. As a result, the wire W drawn out from the winding frame 1 is guided so that the wire W is smoothly fed in the axial direction while turning in the circumferential direction of the winding frame 1.

Reference numeral 6 denotes a fixture for the wire rod guide member 2 screwed to the tip of the mounting shaft 10 so that the wire rod guide member 2 does not come off from the mounting shaft 10, and is composed of, for example, a fixing nut. Further, a cone-shaped hood 7 having a hood outlet hole 7A in the front part is disposed in front of the wire rod W of the wire rod guide member 2 that is fed out, and is held by a support base 3B of the reel support car 3.

As shown in detail in FIG. 2, the damper member 8 is constituted by a coil spring 11 which is an example of a spring member for urging the wire rod guide member 2 toward the winding frame 1. The coil spring 11 is formed, for example, by spirally winding a metal wire having a spring property at a predetermined winding diameter, winding pitch, and number of turns. This coil spring 11 is used for the wire rod guide member 2
With respect to the bobbin 1 which is located on the opposite side of the collar plate 1A, between the fixing tool 6 and the wire rod guide member 2, on the outer periphery of the mounting shaft 10 and coaxially with the bobbin 1. Has been done. When the fixing tool 6 is rotated to change the initially set length of the coil spring 11, the spring force for urging the wire rod guide member 2 toward the winding frame 1, that is, the spring force associated with the displacement of the wire rod guide member 2 is applied. It can be adjusted to accommodate the size of W, the feeding tension, the speed, and the like.

The wire rod feeding device of the present embodiment has the above-mentioned structure. The wire W is drawn out from the winding frame 1 while being swung in the circumferential direction of the winding frame 1 by a pulling force from a wire rod processing facility (not shown). Then, it is led out in the axial direction of the reel 1 while being in contact with the wire rod contact edge portion 2B of the wire rod guide member 2 rotatable around the central axis of the reel 1. At this time, the wire rod guide member 2 is compressed by the coil spring 11 constituting the damper member 8 by the feeding tension of the wire rod W, and the reel 1 is wound.
It is displaced by a predetermined amount in the direction away from (direction of arrow X in FIGS. 1 and 2), that is, the front of the bobbin 1, and is held at a position balanced with the spring force of the coil spring 11. Further, the wire W passes through the inside of the hood 7 and is drawn out from the hood outlet hole 7A toward a wire rod processing facility (not shown) with a predetermined drawing-out tension.

When the wire rod W is being fed from the wire rod feeding device at a predetermined feeding tension, the take-up tension of the wire rod W, that is, the feeding of the wire rod W, due to a change in the operating state of the wire rod processing equipment. When the tension fluctuates, for example, when the tension sharply increases, the pressing force from the wire rod W increases and the wire rod W is further moved in the axial direction of the winding frame 1 from the position where the pressure wire rod guide member 2 is balanced. It is displaced by a predetermined amount in the direction (the direction of the arrow X in FIGS. 1 and 2) that is fed out. As a result, the feeding speed of the wire W increases, so that the feeding tension of the wire W decreases and the original tension is quickly restored. Conversely,
When the payout tension of the wire rod W is suddenly reduced, the pressing force from the wire rod W is decreased, and the wire rod W is fed from the position where the wire rod guide member 2 is balanced in the opposite direction to the wire rod W in the axial direction. A predetermined amount is displaced in the direction (arrow Y direction in FIGS. 1 and 2). As a result, the feeding speed of the wire W is reduced, so that the feeding tension of the wire W is increased and the tension is quickly returned to the original set tension.

As described above, the wire rod guide member 2 is provided with no matter how quickly the feeding tension of the wire rod W, which is pulled out from the reel 1 and swung in the circumferential direction of the reel 1, and which is reeled out in the axial direction, fluctuates. The tension of the wire W is promptly absorbed by the displacement of the winding frame 1 in the axial direction along with the change in tension.
Therefore, the tension fluctuation of the wire rod W is quickly returned to the original set tension, and the wire rod W is prevented from being constricted, broken, kinked, twisted and disturbed, etc. to improve the operating rate of the equipment and the yield of the product, and to obtain good quality. Can be manufactured.

In FIG. 3, as the damper member 8, an annular disc spring 12 which is another example of a spring member for urging the wire guide member 2 toward the winding frame 1 is used.
As shown in FIGS. 4A and 4B, the disc spring 12 is formed by molding a metal annular plate having a spring property into a truncated cone shape. Depending on the usage conditions, only one disc spring 12 may be used, but it is preferable to use a plurality of disc springs 12 arranged in series so that the concave portions and the convex portions face each other and face each other. Then, like the coil spring 11, these disc springs 12 are located on the side opposite to the collar plate 1A of the winding frame 1 with respect to the wire guide member 2, and between the fixture 6 and the wire guide member 2, On the outer periphery of the mounting shaft 10,
Moreover, it is arranged coaxially with the reel 1.

When the damper member 8 is composed of spring members such as the coil spring 11 and the disc spring 12, the response to the tension fluctuation of the wire W becomes faster, so that the feeding speed of the wire W becomes higher. Also, it becomes possible to quickly absorb the fluctuation in tension, and product productivity can be improved. Further, since the spring member is lightweight and compact and does not take up a space for its attachment and is easily attached, the structure of the feeding device is simplified and the cost of the device can be reduced, which is preferable.

In the apparatus of the above-described embodiment, the wire rod guide member 2 is axially displaceable on the mounting shaft 10 mounted on the front guard plate 1A side of the bobbin 1 and around the central axis of the bobbin 1. Although it is rotatably arranged, it may be arranged at the tip of the support shaft 4 that supports the winding frame 1. Further, the wire rod guide member 2 is rotatably arranged around the central axis of the winding frame 1, but is fixedly held by the mounting shaft 10 or the support shaft 4,
Although it is displaceable in the axial direction of the winding frame 1, even if it is arranged so as not to rotate around the central axis of the winding frame 1, by providing the damper member 8, the wire rod guide member 2 It is possible to absorb fluctuations in the feeding tension of the wire W and effectively reduce the fluctuations without actively rotating the wire.

Therefore, although the structure of the feeding device can be simplified and the manufacturing cost can be reduced, it goes without saying that the wire guide member 2 may be driven to rotate in the feeding device of the present invention. By doing so, even when the wire tension is suddenly and significantly changed,
This severe tension fluctuation can be quickly absorbed and controlled to a preset normal tension.
It is possible to easily deal with the case where the wire W is drawn out, or when the wire W needs to be drawn out with a small drawing tension because the tensile strength is weak.

Further, in the above-described embodiment of the present invention, the coil spring 11 or the disc spring 12 is exemplified as the damper member 8. However, in addition to this, for example, an air spring member or a shock operated by commercially available air or oil or the like. You may make it use an absorber.

[0025]

As described above, according to the wire rod feeding device of the present invention, the winding frame in which the wire rod is wound and housed, and the winding frame which is arranged adjacent to one side in the axial direction of the winding frame, are provided. In a feeding device provided with a wire rod guide member for guiding the wire rod so that the wire rod pulled out from the wire reels out in the axial direction while turning in the circumferential direction of the winding frame, the wire rod guide member is wound along with the tension fluctuation of the wire rod. Since a damper member is further provided for displacing the tension of the wire rod by displacing it in the axial direction of the frame, the feeding tension of the wire rod drawn out from the reel and fed in the axial direction while turning in the circumferential direction of the reel. However, the wire rod guide member can be promptly displaced in the axial direction of the winding frame due to the change in tension, and the wire rod feeding tension can be quickly absorbed. Therefore, the tension fluctuation of the wire rod is quickly returned to the original set tension to prevent the wire rod from becoming constricted, broken, kinked, and twisted, thereby improving the operating rate of the equipment and the yield of the product, and at the same time, the product of good quality. Can be manufactured.

Further, the damper member is a spring member for urging the wire rod guide member toward the winding frame, and is located on the opposite side of the wire rod guide member from the winding frame so as to be coaxial with the winding frame and the wire rod guide member. If it is arranged, the response to the tension fluctuation of the wire rod becomes faster, so it is possible to quickly absorb the tension fluctuation even if the feeding speed of the wire rod increases.
Product productivity can be improved. Further, since the damper member is lightweight and small, it does not take up a space for its installation, and its installation is easy, so that the structure of the feeding device is simplified and the cost of the device can be reduced. Furthermore, the spring length associated with the displacement of the wire rod guide member can be adjusted by changing the initially set length of the spring member so as to be adapted to the wire rod size, the feeding tension, the speed, etc., and the wire rod feeding workability is improved. It is possible to do so, which is preferable.
