DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device and a winding method, and more particularly to a device and a method for winding a wire on a non-circular core having a rectangular or elliptical cross section.

[0002]

2. Description of the Related Art A conventional winding method for a cylindrical core is a so-called axial winding method in which a core is rotated to wind a wire.
Alternatively, a so-called flyer winding method is known in which a wire is rotated and wound while the core is not rotated. When the wire is wound around the core having a non-circular cross section, the above method is used, and the wire W is rotated by rotating the center position of the core C having a rectangular cross section as the rotation center o as shown in FIG.
Is wrapped around.

[0003]

In the above-mentioned conventional winding method, when the core has a circular cross section, the winding speed and the tension of the wire do not change, but the core has a rectangular or elliptical cross section. In the case of, the tension changes between the position shown by the solid line and the position shown by the virtual line as shown in FIG.
The winding speed also changes, the wire pulling direction also changes,
Unable to obtain certain dimensions and performance.

[0004]

In order to solve the above problems, a winding device according to the present invention is a rail holding member having a chuck member for holding a non-circular core and a rail with which the chuck member engages. Then, the winding device is configured by a rotation driving unit that rotates the rail holding member and a slide driving unit that linearly moves the chuck member holding the core along the rail.

In the winding method according to the present invention, a core having a non-circular cross section is linearly moved in the longitudinal direction, and the core is rotated by 180 ° around one end in the longitudinal direction as a center of rotation to wind the wire. Then, the core is linearly moved again in the lengthwise direction, and the core is rotated 180 degrees with the other end of the core in the lengthwise direction as the center of rotation.
Rotation was repeated.

[0006]

[Function] Since the wire is wound while the core is linearly moved and eccentrically rotated, the change in tension, the winding speed,
Changes in the tensile direction of the wire are reduced, and dimensional accuracy and performance can be stabilized.

FIG. 4 is a sectional view taken along line BB in FIG. 2, and FIG. 4 is an explanatory view of a winding process.

The winding device holds the core C rotatably and linearly movably by the core holding unit 1, and rotates the entire core holding unit 1 to rotate the core C. A core slide drive unit 3 for linearly moving the core C of the core holding unit 1;

The core holding portion 1 rotatably supports the rotating shaft portions 9 and 10 of the rail holding members 7 and 8 on the upper ends of the columns 5 and 6 which are erected on the base 4, and these rail holding members 7 and The guide rails 11 and 12 are fitted to the guide rails 8, and the engaging portions 16 and 17 provided on the back surfaces of the chuck members 14 and 15 that hold the core C from both sides thereof are slidably fitted to the guide rails 11 and 12. ing.

[0010] By rotating the rail holding member 8, the core C held and held by the chuck members 14 and 15 rotates, and the chuck members 14 and 15 slide along the guide rails 11 and 12. As a result, the core C linearly moves and is eccentric with respect to the rotation center of the rail holding member 8.

Further, the core rotation drive unit 2 has a drive motor 20 attached to the upper end of a column 19 standing on the base 4.
The coupling member 2 is attached to the rotary shaft 21 of the drive motor 20.
The rotary shaft member 23 is connected via 2 and the rotary shaft member 2
The rotating shaft portion 10 of the rail holding member 8 is connected to 3.

The rotary shaft portion 10 of the rail holding member 8
The stopper rods 25 and 26 are inserted so that they can advance and retreat,
The springs 27 and 28 bias the chuck member 15 side,
The tip side of the stopper rods 25 and 26 is attached to the chuck member 1
5, a rod driving means 3 for advancing and retracting the stopper rods 25 and 26 to and from support members 29 and 30 attached to the support 6 on the rear end side of the stopper rods 25 and 26.
The chuck members 15, that is, the core C, can be reliably stopped in a predetermined state by disposing the stopper rods 1 and 32 and moving the stopper rods 25 and 26 forward and backward.

In the core slide drive unit 3, an air cylinder 36 is attached to the upper end of a column 35 standing on the base 4, and a rod 37 of the air cylinder 36 is attached to the column 35.
One end of the slider plate 38 slidably mounted on the slider plate 38 is connected to the other end of the slider plate 38 via a connecting member 39. Engagement holes 40, 40 are formed in the other end of the slider plate 38.
When the engaging pin members 41 and 42 which are planted at 0 and the symmetrical positions of the chuck members 14 and 15 are engaged with each other, the slide plate 38 slides and the chuck members 14 and 1
5 moves linearly along the guide rails 11 and 12. Then, stopper members 43 and 44 for restricting the moving ends of the chuck members 14 and 15 are provided at both ends of the rail holding members 7 and 8.

In order to wind the core C with the winding device constructed as described above, as shown in FIG. 4A, the core C sandwiched between the chuck members 14 and 15 is horizontal in the longitudinal direction. And one end portion of the core C in the longitudinal direction is the chuck member 1.
4, the wire W is wound around the short winding surface Ca of the core C to the long winding surface Cb.

Thereafter, the air cylinder 36 is operated to slide the slide plate 38 in the direction of the arrow, so that the engagement pin member 4 is inserted into the engagement hole 40 of the slide plate 38.
The chuck members 14 and 15 which are engaged with each other via 1 are driven by the movement of the slide plate 38 to move along the guide rails 11 and 12.
The winding surface Ca linearly moves along the direction until it abuts the stopper member 44, and the other ends of the chuck members 14 and 15 in the longitudinal direction are aligned with the rotary shaft portion 10 of the chuck member 14 as shown in FIG. Eccentric to the position.

Then, the rail holding member 8 is rotated by the rotational driving force of the drive motor 20, and the chuck members 14 and 15 are rotated to rotate the core C in the arrow direction as shown in FIG. By setting the state shown in FIG. 3C, the wire W is wound around the winding surface Cc of the core C, and the slide plate 38 is returned by the air cylinder 36 in the direction of the arrow, and the core C is rotated. By setting the winding surface Cd of the core C on the upper side as shown in (d), the wire W is wound around the winding surface Cd of the core C.

Then, the wire C is wound around the core C by linearly moving the core C again so that the center of rotation is at one end side in the longitudinal direction of the core C and performing the same operation.
By repeating this operation a predetermined number of times, a predetermined number of windings can be applied.

In this way, the center of rotation of the core C repeats eccentricity from one end to the other end, and from the other end to the one end.
The tension applied to the wire W and the winding speed do not change much, and the dimensional accuracy and performance are stable.

In the above embodiment, the wire is wound around the core having a rectangular cross section, but the present invention can be similarly applied to a non-circular core such as a core having an elliptical cross section. Further, the wire is not limited to an electric wire and the like, but also includes a tape and the like. Furthermore, the present invention can be applied to a sealing device in which an adhesive is applied to the peripheral surface of a work.

[0020]

According to the present invention as described above,
Since the wire is wound while the core is moved linearly and eccentrically rotated, a change in tension, a winding speed, and a change in the pulling direction of the wire are reduced, and dimensional accuracy and performance can be stabilized.
