Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a carrier in a continuous wire winding device for continuously winding two or more wires around a tubular body that moves in the axial direction.

[Technical background of the invention]

In general, a continuous strand winding device is attached to a raceway surface plate 2 that fits around a tubular body IVC that moves in the direction of the axis a, and is attached to this surface plate, and is moved regularly toward and away from the axis a. It consists of a carrier 4 which is a tubular body and supplies the strands. As shown in FIG. 2, the strands 3 made of metal wires, fibers, etc. with a relatively small wire diameter are composed of one strand 3a, 3b...
It is necessary to supply the desired number of 3b... from one carrier.

The carrier 41c is still composed of a bobbin 4a around which the strands 3 are wound, a strand supply frame 4b that sends the whole a3 drawn out from the bobbin 74a to the source A, and a base 4'j that supports these. Regarding the moving state of this carrier 4 on the orbital surface plate, the above-mentioned wire supply frame 4b' shown in FIG.
, 4 b” movement.

That is, while the adjacent strand supply frames 4b' and 4b'' move in opposite left and right directions (in the drawing, 4b' rotates clockwise, 4b// counterclockwise), the frame 4b/ is rotated counterclockwise. The wire 3' is wound around the tubular body 1 in a right-handed manner, and the frame body 4b'' is made of plain #J3/
/ is wound around the tubular body in a left-handed manner.

In the olden days, the frames 4b' and 4b'' alternately and synchronously rotated to completely pass through the intersection 22, and moved inward and outward to pass through each other, thereby forming the tubular body 1. By the way, in the conventional gear rear, all three strands can be braided.[Conventional technical advantage]
3a13b13C... are wound around one bobbin 4. (See Fig. 9) Each strand drawn out from the bobbin 4 passes through a strand bundle 7 fixed to the shaft, changes its direction by 90 degrees, and then passes through a movable wire bundle 7 fixed to the shaft. Boo IJ-9K led. The three wires that passed through the movable pulley 9 are turned around 180 degrees and supplied to the compiler A. Then, when the carrier is about to go out, the movable pulley 9 pushes up the stopper 10 while compressing the compression springs 8 and 8', and at the same time is connected to the stopper 10 so that the wire will be pulled out from the carrier. The lock between the pawl 11 and the gear 12 fixed to the lower end of the bobbin 4 is released, and the bobbin 4 rotates on the spindle 13 to feed out the wire 3. On the other hand, when the carrier tries to enter the carrier, it is necessary to pull the strands back into the carrier, the compressed springs 8 and 8' stretch, and the movable pulley tries to return to its normal state. , At the same time, gear 11 and gear 1
2 engage again, the rotation of the bobbin 4 is prevented, and the supply of the strands is stopped. The above operations are repeated to braid the strands around the outer periphery of the tubular body, but since the strands and wires are wound around one bobbin, the strands with the highest tension It is dominated by the wire, that is, the shortest strand, and even loose strands are forced to be pulled out. Furthermore, at the beginning of operation, all the strands are in tension, but as time passes, some strands are seen to become loose. In other words, out of the number of strands, some are taut, while the remaining strands are loose. By the way, when braiding was carried out around the outer periphery of the tubular body under these conditions, problems such as overlap between the number of strands and loose strands protruding outward in an Ω-shape occurred. As a result, the resistance of, for example, a braided tubular body (or the resistance of a hose: 1°, 1 degree, 1 needle) is significantly reduced. Furthermore, it is necessary to wind two or more strands of wire to the same length on one bobbin, which is a very time-consuming task. Furthermore, the wire feeding method rotates the bobbin through the meshing action of the pawl and a gear fixed to the bottom end of the bobbin.
Alternatively, since the wire is fed by stopping, the bobbin and the pawl collide with each other, producing a harsh sound, which is extremely noisy and pollutes the working environment. Or, if you want to change the number of bobbins held, you will have to prepare as many bobbins with different numbers of bobbins and reinstall them, which is a very time-consuming task. Also, spring 8
, 8' uses a compression spring, so when the spring expands and contracts, a frictional force is generated between the spring itself and the shaft, and as a result,
This results in a large gap between the tension of the wire when it is pulled out from the carrier and when it is pulled back. That is, in other words, the impact force of the strands wound around the tubular body becomes uneven, which ultimately causes a decrease in the pressure resistance of the tubular body.

[Purpose of the invention]

The present invention aims to solve the drawbacks associated with such prior art, and by independently supplying all the strands in the required length according to the requirements of the network operator, it is possible to overcome the conventional technology. It is an object of the present invention to provide a carrier for a continuous strand winding device that allows each strand to be wound around the outer periphery of a tubular body with uniform tension without causing any slack between the number of strands held. In particular, the present invention aims to wind the wire around the outer periphery of the tubular body with uniform tension by minimizing the variation in the tension of the wire within the carrier.

Another object of the present invention is to improve the working environment by minimizing noise during wire winding work. Still another object of the present invention is to provide a carrier that does not require much effort and allows the number of wires to be changed to be changed by simply increasing or decreasing the number of bobbins.

[Summary of the invention]

The carrier in the continuous winding device for strands of the present invention includes a base that moves regularly on a track surface plate, a bobbin group held by a spindle vertically disposed on the base, and strands pulled out from the bobbin group. It is composed of a strand supply frame body that supplies the wire to the tubular body. The bobbin group is superimposed on the spindle so that the number of bobbins wound with a single zero wire can be rotated independently under constant rotational resistance. The strand supply frame body also includes a direction changing boob IJ u that changes the direction of the strands pulled out from each bobbin, a floating pulley that changes the direction of the strands, and moves up and down according to tension fluctuations of the strands, and a spring. Movable members for tensioning the strands by means are sequentially arranged.

[Detailed description of the invention]

(al) Next, a detailed explanation of the invention will be explained based on the drawings.The carrier 4 in the present invention includes a base 4C that regularly moves the orbital surface plate 2 as described above, and a base 4C that is vertically installed on the base 4C. A bobbin group 40A held by a spindle 23, and a wire supply device that is vertically disposed on the base 40, tensions the strands 30 pulled out from the bobbin group, changes direction, and supplies the strands We to the narrow light A. It is composed of a frame body 40B.

The bobbin group 40A is made of a single strand 30'.

It is held by a spindle 23. That is, one strand of wire is wound on one bobbin, and the number of bobbins is the same as the number of bobbins. And these bobbins 4ON.

40M 40N//... By rotating each bobbin independently under constant rotational resistance, the single strands 30', 30'', 30'',... meet the requirements of the wire manufacturer. Each will be supplied accordingly. Therefore, as a preferable means for applying a certain degree of rotational resistance between these bobbins, a pressing spring such as a plate spring or a disc spring is pushed from the north end of the 24-karat gold spindle 23 to press the uppermost bobbin 4ON. There is. Since the pressing force in this case can be adjusted by the tightening force of the nut 25 screwed onto the spindle, the resistance force against rotation of each bobbin can be controlled. In order to ensure smooth rotation of each bobbin, it is preferable to interpose a friction material 26 between each bobbin, which is made of a fluororesin without stake slip, particularly tetrafluoroethylene resin, or the like.

Note that the winding direction of each single strand may be the same as that of the opposing bobbin, but if the winding direction is reversed, the rotation direction of the adjacent bobbins will be opposite, and one bobbin will rotate. When a single strand is drawn out, the bobbins on both sides try to rotate in a direction opposite to the direction in which the single strand is pulled out, so that the single strand becomes more stretched.

Also, if the winding directions of the adjacent bobbins and the wires are the same, one bobbin rotates and the adjacent bobbins rotate in the same direction.
In order to prevent the shaft from rotating due to the influence of the rotation, it is necessary to take measures such as digging a key groove in the shaft so that the friction material interposed between the pobbins does not rotate.

This is a group of pulleys that change direction by 90 degrees. The cylindrical pulleys are loosely fitted onto the shaft 28 and each cylindrical pulley 2
9', 29", 29"75E can be rotated independently in one step to draw out the strands from each bobbin. A group of 90-degree direction change pulleys is also installed on the shaft 32 in parallel with the cylindrical pulleys, and the direction change pulleys IJ 31', 31", 31"', . . . By shifting the wires little by little as shown in the figure (to the right with respect to the front in Figure 4), each single strand can be lined up five times to the next pulley without overlapping. Note that the cylindrical groove is not necessarily required depending on the position of the 90-degree turning pulley group.

This is a floating pulley that changes direction by 180 degrees and moves up and down as the tension of the wire θ changes.

This floating pulley 33 is resiliently supported by a spring 35 on a base plate 34 fixed to the head of the shaft 28,32. For example, a floating pulley can be supported by two shafts, and a compression spring can be inserted into the shaft between the bobber shaft and the plywood to make the pulley resilient. can be supported.

Next, 38 is a movable member that moves up and down (2 shirts hanging vertically in parallel on the base 4 roC1) 36.37 (5).

Therefore, this movable member 3B has a boot 93 attached to the side surface.
9, and a spring 50 stretched between the lower end of the 5T moving member and the lower end of the shaft 36. The pulley 39 changes the direction of the wire 30 guided by the floating pulley 33 again by 180 degrees and sends it out to the net source A.
The spring 50 has the function of expanding and contracting in accordance with the movement of the movable member that raises and lowers the shirt 36 and 37, and applies full tension to the wire 30. In particular, it is best to use a tension spring for the present invention. Reference numeral 51 denotes a base plate supported by shafts 36 and 37 at the upper end of the wire supply frame 40B. You can change direction. Incidentally, in order to simplify the preparation of the strands before operation of the apparatus, it is preferable to provide slits 54 and 56 large enough for the strands 30 to pass through.

It converges at this floating goo 933, turns 180 degrees, and heads toward the pulley 39 at the bottom. Then, the direction is changed again by 180 degrees, and the wire passes through the supply roller 53 disposed at the upper end of the wire supply frame 40B and is supplied to the net source A.

Thus, the carrier 11-1 in the present invention: As explained in FIG. , since the distance between the carrier and the axis becomes long, the wire 30
tries to be pulled out of the carrier. At this time, the movable member 38 stretches the spring 50 and rises, and at the same time, the bobbin group rotates and the strands are supplied. If even one single strand of wire is not long enough, the bobbin around which that single strand is wound will rotate independently of the other bobbins. , only the essential length of the strand is brought out. Conversely, as the carrier approaches the axis, the distance between the '@1 core and the carrier becomes shorter, so the carrier needs to pull the strands back into the carrier. Therefore, the stretched spring 50 attempts to return to its original state and contracts, allowing the movable member 38 to pull the F-dropped wire back into the carrier.

By overcoming this, the wire is supplied, and its rotational resistance, that is, the tensile force of the wire, is adjusted by the force that presses the bobbin group. However, frictional force is generated in the contact portion of the wire with each insertion pulley. Further, frictional force is also generated in one circle between the spring and the shaft. This means that if a tension spring 50 is used as in the embodiment of the present invention, no frictional force will be generated between the spring and the shaft, but if a compression spring is used, for example, the compression spring will be loosely inserted into the shaft 36. A frictional force is generated between the shaft and the spring due to the expansion and contraction of the spring.

In this way, when various frictional forces occur, a difference occurs between the tension of the wire at the base of the wire and the tension of the wire at the bobbin drawer.
The movement of the wire cannot be accurately transmitted to the bobbin drawer.

At this point, the floating pulley 33 moves up and down elastically when a tension difference occurs between the strands, and this up-and-down movement causes the pulley to slightly rotate left and right. The difference in tension between the wires is reduced and narrowed. Figure 7 shows changes in the tension of the wires when the carrier of the present invention approaches and moves away from the track surface plate. The horizontal axis represents the tension spring. The vertical axis of the deformation ridge 50 is the tensile force at the base of the wire.Now, when the carrier tries to move from the inside of the track to the outside, the tension spring 50 is stretched, so the tensile force is P. −)
When the bobbin rotates and the wire is supplied when the 9th point is reached, the value changes to Q −+ fl. Next, when the carrier moves from the outside of the track to the inside [7], the tension spring contracts in an attempt to return to its original state in order to pull it back into the strand carrier, so the tension changes from 1t to S.
Return to point 8. Therefore, by increasing the pressing force of the push spring 24 acting on the bobbin, the loop of tensile force P-+Q→1t→S due to the movement of the carrier is changed to 1'→q→l(, /→S
'-3 and can be pulled down to F.

In this way, by adjusting the pressing force acting on the bobbin, it is possible to simply change the tension of the cable wire within the limits of the tension spring (ff1) without replacing the tension spring. A compression spring can also be used instead of the tension spring.

[Effects of the present invention]

B The carrier in the VC of the present invention has a number of wires wound around independent bobbins, and each wire is independently pulled to the required length according to the requirements of the network operator. Because it can be pulled out, there is no slack in the strands.

If the bobbins are polymerized, the pressing force when pressing the bobbin group will be applied uniformly to each bobbin, so the rotational resistance force will be the same for all bobbins. Therefore, the tensile force required for pulling out a single strand is the same for a single strand, and the strands can be wound uniformly around the outer periphery of the tubular body.

C. The floating pulley, which moves up and down elastically, eliminates tension fluctuations in the strands caused by friction, and reduces the difference in tension in the strands between the bopi and the net base. therefore,
Since the strands can be evenly and uniformly wound around the tubular body, the compressive strength of the knitted tubular body increases. In particular, if the movable member is tensioned, there is no frictional force between the spring and the shaft, so there is no need to consider the difference in tension caused by the friction of the tension wire.

Since the wire is drawn out from the bobbin by slip rotation between each bobbin, there is no harsh noise caused by the collision between the bobbin and the claw as in the conventional case. Especially with tetrafluoroethylene resin between the bobbins! If fluororesin is used, the slip rotation will become even smoother.

Furthermore, when you want to change the number of wires you have, you just need to increase or decrease the number of bobbins, and there is no need to prepare bobbins for each number of wires you have, unlike in the past.

According to the above 5IC, when internal pressure is applied to the tubular body braided with the carrier of the present invention, each single strand is braided with uniform tensile force without slack, so the internal pressure is applied equally to each single strand. The contribution efficiency of the strands to the withstand voltage is greatly improved, and the withstand pressure strength and safety factor are significantly improved compared to the conventional method. Moreover, compared to the conventional method, the work efficiency is better and the manufacturing cost of the braided pipe can be significantly reduced.

(Example) A tetrafluoroethylene resin tube is used as a tubular body, and its -
A stainless steel wire was braided on the top. The conditions at this time were the same as for the bottom manure.

(Conditions) Tetrafluoroethylene resin tube: Inner diameter 1'8.0mm
Outer diameter i 10.0 Stainless steel wire: SUS 3
04-WPB Number of strands held between wire diameter 0128 = 5 Number of strokes: 24 Tensile force applied to the entire number of strands held: 3.5kgf Braiding angle
: 110 degrees (bag version) Pushing force of push spring: 4.6 kgf Therefore, in this example, the entire bursting pressure of the braided tetrafluoroethylene resin tube was measured at room temperature. As a result, the braided one using a conventional carrier weighed 820 kgf/(7
However, the one in this example was 1100 kgf/ffl
and improved. Overlap of strands between the number of wires and Ω
There were no protrusions, and the appearance was very good.

Next, we measured how low the noise was using a sound level meter, and found that when the revolution period was 8.3 sec/times, the conventional device had a maximum of 96 horns, but this example had a maximum of 83 horns. A decline was observed.

? The eleventh is the tension loop (,TA
) and the tension loop TB in the conventional carrier 9. Comparing the gap between the Q point where the wire is supplied and the R point where the wire is pulled back, the loop gap in this embodiment (QA- R people) is smaller than the loop gap (Q - RB) in conventional carriers. Therefore, there is no unevenness in the winding force of the wires braided into a tube or shaped body, and even when internal pressure is applied, all the wires are evenly distributed, and the pressure resistance is improved. On the other hand, with conventional carriers, the winding force of the strands is uneven due to the large loop gap, and as a result, the load is applied only to the strands where the winding force is large. Magnetic breakdown occurred in that area, reducing pressure resistance.
