Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device for winding a wire such as a conductive wire or glass fiber around an L-shaped core.

[0002]

2. Description of the Related Art A method for manufacturing a welded joint is disclosed in JP-A-63-
As described in Japanese Patent No. 71323, there is a method in which a core around which a conductive wire is wound is fitted into a mold and injection molding is performed.

Therefore, conventionally, when an L-shaped welded joint generally called an elbow is manufactured by this manufacturing method, the L-shaped welded joint can be divided into two parts, a first part and a second part. A core was used and a conductive wire was wrapped around the core.

That is, as shown in FIG. 3, first, the core 30 in which the first component 10 and the second component 20 are joined is fixed to the rotating shaft 40 in a cantilever state, and the core 30 is rotated in this state. The conductive wire 40 is wound around the first component 10 while being performed. After that, once remove the core 30 from the rotary shaft 40,
Next, the second component 20 is fixed again to the rotating shaft 40, and the conductive wire 5 is attached to the second component 20 while rotating the core 30 in the same manner.
Wrap 0.

[0005]

However, in such a conventional winding device, a work of re-fixing the core 30 to the rotating shaft 40 is performed during the winding work of the conductive wire 50, which causes a discontinuous operation. Since it requires work, work efficiency is poor.

Further, one component (first component 10 in the figure) constituting the core 30 is fixed to the rotary shaft 40 to fix the core 3 thereto.
0 is attached, the other component (second component 2 in the figure)
0) is in a state of protruding in the radial direction. Therefore, when the core 30 is rotated, the mass of the other component 20 causes the core 30 to rotate.
Is shaken in the radial direction. Therefore, it is difficult to wind the conductive wires 50 at a constant pitch.

In addition, after the conductive wire 50 is wound around the first component 10, the conductive wire 50 is connected during the re-fixing work of the core 30 for winding the conductive wire 50 around the second component 20. If the work is carried out while it is kept twisted, the conductive wire 50 is likely to be twisted, and a skilled technique is required to prevent such twist.

In the present invention, attention is paid to the above problems, and L
An object of the present invention is to provide a winding device in which a conductive wire can be efficiently wound around a V-shaped core, and moreover, a pitch shift or a twist of the conductive wire hardly occurs.

[0009]

The present invention provides a winding device,
The above-mentioned object is achieved by the structure in which the guide member is rotatable around the support member.

That is, the winding device of the present invention comprises a guide member capable of guiding the wire while applying a constant tension, and a support member capable of supporting the L-shaped core, and the guide member supports the support. The support member is rotatably fixed around a member, and the support member is arranged such that one end of the core is parallel to the rotation center axis of the guide member and the other end of the core is parallel to the rotation center axis of the guide member. The support member and the guide member are rotatably fixed to a certain position, and the support member and the guide member are provided so as to be movable in parallel with respect to the rotation center axis of the guide member.

[0011]

When a wire such as a conductive wire or glass fiber is wound around an L-shaped core using the winding device of the present invention,
First, the core is supported by the support member, and one end of the wire rod guided by the guide member is fixed to one end of the core aligned in parallel with the rotation center axis of the guide member.

Next, the rotating member is actuated to rotate the guide member around the support member, and the support member and the guide member are relatively moved in parallel with respect to the rotation center axis of the guide member. Wrap the wire toward the bend.

When the winding work of the wire is completed before the bending portion of the core as described above, the rotating member is operated to move the supporting member to the position where the other end of the core becomes parallel to the rotation center axis of the guide member. Rotate. At this time, the wire rod can be wound around the bent portion of the core by continuing the rotation of the guide member and the relative parallel movement of the support member and the guide member.

Further, while the other end of the core is parallel to the rotation center axis of the guide member, the rotation of the guide member and the relative parallel movement of the support member and the guide member are continued to bend the core. Wrap the wire from one part to the other end.

In this way, one continuous wire can be wound from one end to the other on the outside of the L-shaped core.

The guide member 1 is composed of a fixed plate 11 and a movable member 12 attached so as to be movable along the longitudinal direction of the fixed plate 11, and a wire W is attached to the movable member 12. A guide hole (not shown) that can be inserted is formed, and an adjusting means (not shown) that can adjust the tension of the wire W is provided.

The guide member 1 is rotatable in the horizontal direction around the support member 3, and the fixed plate 1 is also provided.
1 is fixed to the rotary table 2 so that the axis 1 is parallel to the rotation center axis S-S.

The rotary table 2 has a supporting surface provided horizontally, and can be rotated in the horizontal direction by a driving device (not shown) such as a motor and can be moved up and down. A bobbin case 5 is fixed to the upper surface of the edge of the rotary table 2.

The support member 3 is formed in such a shape that the L-shaped core C can be fitted thereinto and supported, and one end of the core C is parallel to the rotation center axis S-S of the guide member 1. From the other end of the core C to the rotation center axis S- of the guide member 1.
It is fixed to the rotating plate 4 so as to be rotatable up to a position parallel to S.

The rotating plate 4 has a lower end portion hinged to a vertically fixed fixing plate 6 and an upper end portion screwed into a screw 7. The lower end of the rotating plate 4 is driven by a motor 8 to drive the screw 7. It is designed to rotate 90 degrees from the vertical position to the horizontal position or from the horizontal position to the vertical position with the section as a fulcrum.

Next, the operation of this embodiment will be described with reference to FIGS. 1 and 2 (a) to (c). 2 (a)-
(C) is a side view showing a work procedure when the wire W is wound around the L-shaped core C using the winding device of the present embodiment. The type of the wire W to be used can be appropriately selected. For example, glass fiber is used when manufacturing an FRP joint, and coated conductive wire is used when manufacturing a welding joint. Further, if the core C that can be divided into two in the length direction is used, the joint can be easily demolded.

When the wire W is wound around the L-shaped core C using the winding device, first, the core C is supported by the supporting member 3 as shown in FIG. At this time, the core C is
The one end (the side not supported by the support member 3) C2 faces downward and is aligned so as to be parallel to the rotation center axis S-S of the guide member 3. Further, the bobbin B is installed in the bobbin case 5, and the wire W drawn from the bobbin B is passed through the hole of the guide member 1 so that a predetermined tension can be obtained.

Then, one end of the wire W guided by the guide member 1 is fixed to one end C2 of the core C aligned parallel to the rotation center axis S-S of the guide member 1. As a fixing method, when a locking means such as a claw is formed on the core C in advance, the wire W can be locked by locking the locking means, or locked on the core C side. When the means is not provided, they may be fixed by welding or adhesion.

That is, the support member 3 is rotated by an angle equal to the complementary angle of the bending angle of the core C (90 degrees when the bending angle is a right angle as shown in the figure). At this time, the rotation of the guide member 1 and the movable member 1
The wire rod W is wound around the bent portion of the core C by continuing the upward movement of 2 and further lowering the rotary table 2. It should be noted that the reason why the rotary table 2 is moved down is that the displacement of the core C is absorbed because the position of the core C shifts downward as the support member 3 rotates.

Then, as shown in FIG. 2C, with the other end C1 of the core C being parallel to the rotation center axis S--S of the guide member 1, the guide member 1 is rotated and the movable member is moved. 12

In this way, one continuous wire W can be wound from the one end C2 to the other end C1 on the outside of the L-shaped core C.

Therefore, in the winding device of this embodiment,
By keeping the rotation speed of the guide member 1 and the moving speed of the guide member 1 constant, the wire rod W is core C at a constant pitch.
Can be wrapped around. Moreover, the pitch of the wire W can be adjusted by adjusting the balance between the rotation speed of the guide member 1 and the moving speed of the guide member 1 upward. Of course, the wire W can be wound around the core C without any gap.

Further, since it is not necessary to re-fix the core C to the support member 3 between the winding start and the winding end of the wire W, the working efficiency is good and the wire W is not twisted.

Furthermore, by completely controlling the rotation speed of the guide member 1 and the moving speed in the vertical direction, and the ascending / descending speed of the rotary table 2 by the controller, it is possible to achieve complete automation.
