In order to connect the shaft 3 to the bobbin driving motor 5 via the coupling 4 and rotate the same, the winding guide 6 is connected to the bobbin so as to uniformly wind the filament 1 according to the winding width of the bobbin 2. The take-up guide 6 is operated to reciprocate linearly or arcuately in the vicinity of the outer diameter portion. In order to operate the take-up guide 6, the operation link 8 and the rotation Link 9
And the operating rotary shaft 11 connected to the rotary link 9
Is rotated by providing another operation motor 10.

[0003] The filament 1, for example, an electric wire, is wound around the bobbin 2 through a winding guide 6 rotatably attached to the tip end of a swing link 7, and connected to a bobbin driving motor 5 via a coupling 4. The bobbin 2 is rotated by the bobbin rotation shaft 3, and the rotation link 9 is rotated by the operation rotation shaft 11 connected to the operation motor 10.
, The swinging link 7 is swung, and the winding guide 6 is reciprocated as indicated by the arrow, thereby uniformly winding. For this reason, the winding guide 6 is moved in the winding direction by the diameter of the filament 1 while the bobbin 2 winds the filament 1 once.

[0004]

As described above, the bobbin driving motor for rotating the bobbin for winding the filament and the operating motor for moving the winding guide are different in installation location and direction, and the number of rotations is also different. Due to the great difference, the bobbin rotation shaft 3 and the operation rotation shaft 11 are provided separately. Therefore, it is necessary to provide a control device for controlling each motor and to perform synchronous operation between the motors in order to perform uniform winding, which not only complicates the control device but also increases the cost. There were problems such as becoming. The present invention has been made in view of the above points, and provides a winding device in which a single motor serving as a power source is used to simplify control.

[0005]

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS This will be described with reference to an embodiment shown in FIGS. 1 is a filament, 2 is a bobbin, 3 is a bobbin rotating shaft, and a drive motor 20
To rotate the bobbin 2. Reference numeral 6 denotes a take-up guide, which is attached to one end of the swing link 7 and is connected to an operation rotary shaft 11 via an operation link 8 and a rotation link 9 connected to the other end of the swing link 7. 21 is a worm attached to the bobbin rotating shaft 3, 22 is a bearing 2
A rotational force transmission shaft supported by 3 and 24 is a worm gear attached to one end of the rotational force transmission shaft and meshes with the worm 21 to transmit the rotational force of the bobbin rotation shaft 3 to the rotational force transmission shaft 22. The rotational speed of the rotational force transmission shaft 22 is reduced from the bobbin rotation shaft 3. 26 is a bevel gear attached to the other end of the rotational force transmission shaft 22, and 27 is the operating rotary shaft 11.
The bevel gear 26 meshes with the bevel gear 26 to transmit the torque of the torque transmitting shaft 22 to the operating rotary shaft 11, and the torque transmitting shaft 22 and the operating rotary shaft 11
Adjust the number of rotations.

The bobbin rotation shaft 3 is rotated by the drive motor 20, and the bobbin 2 attached to the bobbin rotation shaft 3
Is wound, the worm gear 25 meshed with the worm 21 causes the rotational force transmission shaft 22 to be reduced and rotated, and the operation rotary shaft 11 is rotated via bevel gears 26 and 27. Therefore, this operation rotary shaft 11
The revolving link 9 attached to the reciprocating unit reciprocates the winding guide 6 via the operation link 8 and the swinging link 7 to uniformly wind the electric wire 1 around the bobbin 2. In order to perform such uniform winding, the winding guide 6 is moved by the diameter of the filament 1 while the bobbin 2 makes one rotation. Therefore, if the number of windings in one row of the bobbin 2 is N,
It is sufficient that the operating rotary shaft 11 makes one rotation with respect to the 2N rotation of the bobbin rotary shaft 3, and the number of rotations is largely different. By performing fine adjustment, a reliable rotation ratio can be obtained.

The rotation transmission shaft 22 and the bobbin rotation shaft 3
May be connected by a bevel gear, and a worm may be attached to the rotational force transmission shaft 22 to connect to the operation rotary shaft 11 by a worm gear, or both may be connected by a bevel gear. Further, the drive motor 20 may be provided on the operating rotary shaft 11, and the rotary power transmission shaft 22 and the bobbin rotary shaft 3 may be connected by a bevel gear to increase the speed of the bobbin rotary shaft 3.

In the embodiment shown in the drawings, the winding guide 6 is reciprocated in an arc by a link mechanism including a swinging link 7. For example, a support plate provided with a rack in the axial direction of the bobbin 2 is provided. The take-up guide 6 is attached to the support plate, the rack provided on the support plate is engaged with the gear attached to the operation rotary shaft 11, and the support plate is moved by the rotation of the operation rotary shaft 11. 6 can be moved in a linear manner.

[0010]

As described above, according to the present invention, a bobbin rotating shaft for rotating a bobbin for winding a filament and a winding guide for reciprocating in accordance with the winding width of the bobbin for uniformly winding the filament on the bobbin. In a winding device provided with an operating rotary shaft for operating a drive motor, only one of the bobbin rotary shaft and the operating rotary shaft is connected to a drive motor, and the other rotary shaft is connected to the rotary shaft connected to the drive motor. Since the motor is connected via a rotating force transmission shaft having gears at both ends, only one drive motor is required, and there is no need for the motor control device to perform synchronous operation, which simplifies the device and reduces cost. The effect is also reduced. Further, a worm is attached by connecting a drive motor to the bobbin rotation shaft, a worm gear meshing with the worm is provided at one end, and a rotational force transmission shaft is provided at the other end of which is connected to the operation rotation shaft via a bevel gear, By greatly reducing the rotational power transmission shaft with respect to the bobbin rotation shaft and adjusting the rotation speed of the operation rotation shaft with a bevel gear, the rotation speeds of the bobbin rotation shaft and the operation rotation shaft are greatly different. The number of revolutions of the bobbin is small, so the bearing is less damaged, the bevel gear can easily adjust the number of revolutions, the take-up guide can be moved properly with respect to the bobbin, and uniform take-up can be performed. The effect is obtained.
