Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for simultaneously horizontally winding a plurality of conductors in parallel.

For example, cords that require high flexibility, such as telephone cords, are manufactured by winding a thin conductor or a thin conductor in the form of a foil around a central thread such as a Telon thread.

The basic method of obtaining such a horizontal conductor winding is to rotate the conductor delivery bobbin 4 that feeds out the conductor 2 around the center line 1 while running the center line 1 as shown in Fig. 1. This is a method of winding the wire around the center line 1 to obtain the horizontal winding wire 3.

The above method is sufficient when there is only one conductor 2, but when there are many conductors 2 and the number of conductor delivery bobbins 4 that send them out increases as shown in Fig. 2, the method described above is sufficient. The conductor delivery bobbin 4 must be rotated together with the bobbin support frame 41 that supports it, and as a result, the centrifugal force may become excessive, resulting in the inconvenience that the number of rotations for horizontal winding cannot be sufficiently increased.

Therefore, in order to improve this inconvenience, as shown in FIG. 3, in principle, the center line sending bobbin 1A that sends out the center line 1 and the winding bobbin 1B that winds the horizontal winding 3 are moved in the same direction at the same time. By rotating the center line 1 itself around the center axis line, the multiple conductors 2 can be wrapped around the center line 1 by simply attaching them to the center line 1 from the lateral direction. A method has been developed to obtain winding 3. However, the device that implements this method is mechanically complex, and the horizontal winding winding bobbin 1 is quite large.
The drawback is that the problem of centrifugal force still persists due to the fact that B and centerline delivery bobbin 1A are rotated together.

The present invention has been made in order to eliminate the drawbacks of the conventional inventions, and provides a novel device for horizontally winding a plurality of conductors around a center line simultaneously and in parallel.

Before describing embodiments of the present invention, the conductor delivery bobbin 6, which is a feature of the present invention, will be explained. This invention uses a delivery bobbin in which a plurality of conductors 2 necessary for horizontal winding are wound in a crosswise manner, and is characterized in that a plurality of conductors 2 are simultaneously sent out in parallel from one bobbin. Now, let's learn how to make this conductor sending bobbin 6.
To briefly explain using the diagram and FIG. 7, the number of conductor delivery bobbins 2A corresponding to the required number of conductors 2
A plurality of conductors 2 sent out from these are arranged in parallel on the outer periphery of the flat capstan 11 through a compound pulley 12 in which pulley grooves are coaxially connected, and here the length of the multi-conductor is determined. Arrange them uniformly. The plurality of conductors 2 having the same length pass through another multiple pulley 12 again, and are wound around the winding bobbin 6 in a crosswise manner by a traverser 13. This winding bobbin 6 directly serves as a conductor delivery bobbin 6 in an embodiment of the invention to be described later with reference to FIG. In addition, in this traverser 13, the seventh
As shown in the figure, in order to keep the conductors 2 parallel and at regular intervals, branch pins 63 are implanted at regular intervals on the cam follower 62 that reciprocates along the camshaft 61. be.

Next, an embodiment of the present invention will be described with reference to FIGS. 4 to 6. A flyer shaft 52 having a substantially hollow cylindrical shape is rotatably supported by the machine frame 50 and rotationally driven by a fixed drive pulley 57. A frame member 51 is attached to the fryer shaft 52 and extends parallel to the centerline at a position radially apart from the center axis, thereby forming the hollow fryer 5. This flyer 5
The above-described conductor delivery bobbin 6 is fixed coaxially and rotatably to the flyer shaft 52 in the hollow portion thereof by a bobbin fixing fitting 6A.

The end of the flyer shaft 52 opposite to the drive pulley 57 mounting side is a hollow cylindrical winding head 52A, and at the tip of the winding head 52A, there is a hollow winding guide shaft coaxially therewith. 54 is extended. The winding head 52A also has a winding guide shaft 54.
A branch metal fitting 53 is erected parallel to and radially shifted from this.

The winding guide shaft 54 and the dividing line fitting 53 are further enlarged and explained in FIG. That is, the winding guide shaft 54 has an introduction slit 54A extending in the axial direction, and the conductor 2 is inserted from the introduction slit 54A.
are introduced and wrapped around the centerline 1, usually in close side-by-side. The wire splitting fitting 53 has a cutting slit 53A for separating wires, and serves to separate the plurality of conductors 2 sent out from the introduction and delivery bobbin 6 via guide rollers 55 and 56 attached to the frame member 51. Let's do it. A delivery bobbin brake 7, such as an electromagnetic brake, is disposed between the conductor delivery bobbin 6 and the flyer shaft 52 in order to apply appropriate tension to the conductor 2 sent out from the conductor delivery bobbin 6.

Next, the operation of this invention, that is, the steps of the method of this invention will be explained. The centerline 1 is sent out from the centerline delivery bobbin 100 and travels vertically from below to above in FIG. 4 through a hollow space inside the flyer shaft 52. When the flyer 5 rotates, the flyer shaft 52 and therefore the winding head 52A also rotate at the same time, so that the plurality of conductors 2 are centered at the introduction slit 54A of the winding guide shaft 54 by the splitter fitting 53. Wound around wire 1 in parallel. As this winding progresses, the conductor delivery bobbin 6 rotates with respect to the flyer 5 by the amount by which the conductor is unwound. In other words, the conductor delivery bobbin 6 rotates faster or slower than the rotation of the flyer 5 by the amount of unwinding, depending on whether the direction of the unwinding rotation is the same as or opposite to the rotation of the flyer 5. Become.

A center line 1 around which a plurality of conductors 2 are wound, that is, a horizontal winding wire 3 which is a target product, is taken up by a capstan 8 and wound onto a horizontal winding winding bobbin 10 by a traverser 9.

In this invention, as detailed above, (i)
Since both the center line delivery bobbin 100 and the horizontal winding winding bobbin 10 are fixed, they can be made larger and can be easily replaced. (ii) Since there is only one conductor delivery bobbin 6 and it is arranged coaxially with the flyer shaft 52, there is no need to worry about centrifugal force and high-speed operation is possible. (iii) The mechanism is shown in Figure 1. (iv) Even though the conductor delivery bobbin with multiple conductors 2 wound around it is quite large, there are many conductors instead of one. The tensile strength is high, and even when this device is operated at high speed, there is no risk of wire stretching or breaking when the bobbin idles due to inertia during startup and stop. Since the slits are provided, the conductors can be guided through these slits one by one and wound around the center line in a close side-by-side manner without cross-contamination. Since it is guided by a hollow winding guide shaft with a slit formed in it, it can travel precisely along the center axis of the fryer, and even if a tensile force is applied in the lateral direction by the conductor being wound, the center line In this case, there is no large deviation in the lateral direction, and as a result, the conductor can be wound in an orderly manner. Once the direction of the opening of the introduction slit of the winding guide shaft is fixed so as to match the running direction of the conductor from the split wire fitting, the conductor can be guided and introduced without straining the conductor at all times during operation of the device. It has great effects such as:
