Description

Description: TECHNICAL FIELD The present invention relates to a wire winding device that spirally winds a wire around a wire to be wound.

[Conventional technology]

For example, for a wire such as an optical fiber, the wire (hereinafter referred to as a wire to be wound) is used to protect the wire or to impart flexibility, corrosion resistance, etc. There is known a configuration in which a wire having a small diameter and predetermined characteristics is spirally wound.

In addition, various devices for automatically winding a predetermined wire on such a wire to be wound (hereinafter referred to as a wire winding device) have been proposed and developed.

[Problem to be solved]

By the way, in such a wire winding device, a wire to be wound on a wire to be wound is uniformly and uniformly wound on the wire to be wound, or a wire which is easily broken. Since there is a case where things are handled, it is an important issue how to establish the tensile force of the wire in the bobbin etc. that supplies the wire, and it is particularly difficult to control it to low tension. I have.

Accordingly, an object of the present invention is to provide a wire winding device suitable for setting and controlling the tension of a wire to be low, particularly in view of the above-mentioned conventional disadvantages.

[Means for solving the problem]

That is, the present invention, when winding the wire to be wound wound on the supply bobbin in a certain direction and winding it around the winding bobbin, the wire is wound around the outer periphery of the wire to be wound during the running. A winding device for winding a wire rod, which has a through-hole through which the wound wire passes and runs through the center, and a rotating shaft that is rotated and driven by a motor, and is integrally fixed to the rotating shaft. A rotating means which rotates, a braking means which is attached to one surface of the rotating body and has a hysteresis brake having a braking axis suspended from the surface; and A vertical bobbin that rotates with the running operation of the wound wire when being wound on the wound wire while unwinding; A first gear that rotates integrally with the bobbin; With the rotation of the rolling element, the revolving body rotates while rotating around the first gear while meshing with the first gear about the braking axis, and the braking force by the braking means acts on the vertical bobbin via the first gear. A second gear for applying tension to the vertical bobbin.

[Action]

In the wire winding device of the present invention, when the rotary plate is forcibly rotated by the motor, the second gear mounted on the rotary plate via the braking shaft moves as a planetary gear with respect to the first gear. In other words, while rotating and revolving while meshing with the first gear, at this time, the braking shaft that supports the second gear brakes the rotational force of the second gear by the braking means, and thereby the second gear is rotated. The rotational force of the first gear meshing with the gear is also braked, and a braking force in a direction opposite to the rotational direction is also applied to the driven bobbin that rotates integrally with the first gear.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a wire winding device according to the present invention. The wire winding device comprises a motor 1, a rotating shaft 2, a rotating body 3, a braking means 4, a driven bobbin 5, 1 gear 6
And a second gear 7.

The motor 1 is installed on the floor, and rotates and drives the rotating shaft 2 via the belt 8.
Incidentally, the motor 1 of this embodiment is, as shown in FIG.
The same wire winding device as that of this embodiment can be simultaneously driven at four positions. In each of the wire winding devices A to D, an optical fiber used as a wire to be wound is used.
On the other hand, glass fiber and silk fiber are wound alternately in two layers each as a wire for winding.

The rotating shaft 2 has an optical fiber which is a wire to be wound at the center.
A through hole through which 10 is inserted is formed, and a pair of supports 1
By means of 0 and 11, they are rotatably supported at a certain height from the floor. As shown in FIG. 2, a plurality of optical fibers 10 previously wound on the supply bobbin 12 are drawn out and forcibly wound on the winding bobbin 13.

The rotating body 3 is formed of a disk-shaped member fixed to the rotating shaft 2, and has a braking means 4 mounted on one surface thereof and a center of gravity located at a point symmetrical position with respect to the center with respect to the braking means 4. A balance weight 14 for position adjustment is attached.

The braking means 4 is a wire rod released from the driven bobbin 5
15 (silk fiber in this embodiment) is for applying a predetermined low tension that does not cause disconnection, and is mounted on the rotating plate 3 using a hysteresis brake using electromagnetic force. The braking force can be set and adjusted with high precision by appropriately controlling the current. It should be noted that the control means 4 is supplied with electric power via the slip ring 16 because of the constant rotational movement.

The driven bobbin 5 has an optical fiber 9 serving as a wire to be wound.
A number of wires 15 to be wound are wound around the rotary shaft 2 and are attached to the rotary shaft 2 in a free rotation state. That is, the driven bobbin 5 is spline-engaged with a sleeve body 17 rotatably mounted on the rotary shaft 2 so that the driven bobbin 5 is free in the axial direction of the sleeve body 17 and rotates integrally therewith. Has become. The driven bobbin 15 is elastically urged leftward in FIG. 1 by a compression spring 18 so that the driven bobbin 15 rotates while being driven by the running operation of the optical fiber 9 via the wire 15. ing. The wire rod 15 pulled out from the driven bobbin 5 is a guide member on the way.
It is wound around the optical fiber 9 while being guided by 19 rollers 19a. Although this guide body 19 is mounted on a second gear 7 described later, a plurality of guide bodies (not shown) are also mounted on a rotating ring body 20 fixed to the rotating shaft 2. .

The first gear 6 is free to rotate with respect to the rotating shaft 2 and is configured to rotate integrally with the driven bobbin 5, and is fixed to a sleeve body 17 in this embodiment. The first gear 6 is connected to the second gear 6 as shown in FIG.
A sun gear meshing with the gear 7 is formed, and while being rotated in a fixed direction together with the driven bobbin 5, a braking force (illustrated by a dotted line in FIG. 3) is applied from the second gear 7 side. It has become.

The second gear 7 is fixed to a braking shaft 4a to which a braking force is applied by the braking means 4, and constitutes a planetary gear that revolves around the first gear 6 while revolving around the first gear 6, as shown in FIG. I have. When the second gear 7 revolves while revolving due to the rotational force of the rotating plate 3, the braking means 4
Is applied in a direction opposite to the direction of rotation as indicated by the dotted line, whereby a constant rotational braking force is applied to the driven bobbin 5 via the first gear 6.

〔effect〕

As described above, according to the wire rod winding device according to the present invention, braking means using a hysteresis brake is provided on a rotating body forcibly rotated by a motor, and the braking means has a direction opposite to the rotating body. When the second gear provided on the rotating shaft to which the braking force is applied revolves around the first gear while revolving around, by applying the braking force to the first gear meshing with the second gear, The braking force from the braking means is transmitted to the vertical gear rotating together with the first gear, and as a result, tension is applied to the released wire, so that the braking force of the braking means is finely set by current control.・ By adjusting, setting / adjustment with low tension can be performed accurately.
