TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a winding device for winding a wire body such as an electric wire around a bobbin.
[0002]
[Prior art]
As an apparatus for winding a striated body on a bobbin, for example, a winding apparatus S for a striated body as shown in FIG. 7 is disclosed in JP-A-53-67060.
The wire winding device S has the following configuration.
A winding bobbin c is fixedly mounted on a column b rotatably supported on a base a, and a winding ring d surrounding the winding bobbin c and having a diameter larger than its flange diameter is arranged. The winding ring d is rotatably held on its outer periphery by a plurality of drive rollers e engaged in frictional contact.
[0003]
The drive roller e is reciprocated in the axial direction of the winding bobbin c by traverse members f and f 'arranged outside the winding ring d. The winding ring d and the traverse members f and f 'are driven by the rotation of the motor M.
A guide roller g is provided on the inner side of the winding ring d, and the supplied filament W is wound around the winding bobbin c by the rotation of the winding ring d via the guide means h and the guide roller g. I have.
[0004]
Since the winding device S for the striated body drives the winding means and the traverse means synchronously by the drive source of one motor M, there is an advantage that a speed control circuit is not required. It is only possible to wind up the striated body of a size, and to change this requires a complicated operation for replacement and adjustment of components such as gears. Since the mounting of the winding bobbin c is performed manually, there is a disadvantage that the operation of the apparatus must be stopped when the bobbin is replaced.
[0005]
Further, since the driving roller e and the winding ring d are in surface contact, slippage occurs during acceleration and deceleration, and uneven winding occurs. Since the guide means h of the striated body W is separated from the guide roller g, "twisting rotation" occurs due to inertia, and an abnormal tension acts on the striated body W during acceleration and deceleration, and a failure occurs. Problems.

I do.
[0025]
When the traverse servomotor 7 and the winding servomotor 8 are driven in a state where the end of the filament W is fixed to the winding shaft 2a, the rotating ring body 6 rotates and at a preset speed. The traverse table 5 moves, and the filament W is wound around the winding shaft 2c of the winding bobbin 2 at a predetermined pitch.
The number of rotations of the traverse servomotor 7 and the winding servomotor 8 can be easily set each time according to the type of the filament W, such as the thickness. On the other hand, the optimum winding speed and winding pitch can be easily set.
[0026]
When the winding of the filament W on the winding bobbin 2 is completed (in a fully-wound state or the like), as shown in FIG. 5, the winding bobbin 2A whose winding has been completed and the empty winding bobbin 2B are separated by a bobbin. By moving the transfer body 12 in the direction of the arrow, the transfer body 12 is transferred to the right side of the bobbin mounting table 3.
[0027]
At this time, since the bobbin supports 13 and 13 'of the bobbin transfer body 12 are fitted in the holes 16 of the flanges of the winding bobbins 2A and 2B, the bobbin 2A and 2B are moved in the direction of the arrow by the movement of the bobbin transfer body 12. Moving. After the movement is completed, the bobbin supports 13 and 13 'are detached from the holes 2b of the flanges of the winding bobbins 2A and 2B, the bobbin transfer body 12 is returned to the original position, and the next empty winding bobbin is arranged. Preparations are being made.
[0028]
While the bobbin transfer body 12 is being moved in the direction of the arrow, the driving of the rotating ring body 6 and the traverse table 5 is continued, and as shown in FIG. 6, the empty winding bobbin 2B is at the winding position. Winding is started immediately upon reaching. When winding is started and the filament W is wound around the winding bobbin 2B several times, the filament W 'in a state where the winding bobbins 2A and 2B are connected to each other is attached to the bobbin mounting table 3. It is guided to the position of the striated cutter 17 by the striated guide 17 (see FIGS. 2 and 3), cut by the operation of the cutting blade 17a of the striated cutter 17, and the winding bobbins 2A and 2B are separated. Is done.
[0029]
If the empty winding bobbin 2B is always arranged on the left side of the bobbin mounting table 3, the bobbin transfer body 12 can be operated without stopping the supply of the filament W and the rotation of the rotating ring body 6. By doing so, it is possible to wind the filament W on a number of winding bobbins 2 continuously.
[0030]
【The invention's effect】
According to the present invention, by employing two servomotors, the winding speed of the filament and the traverse speed can be set arbitrarily, so that the winding pitch can be set freely. It can be wound with a single winding device from a thin one to a thick one. Since the rotation of the rotating ring body can be controlled, abnormal tension is not applied to the striated body, and high-quality winding without uneven winding can be performed. In addition, since the twist is applied once (360 degrees) for each rotation of the rotating ring body, twisting can be eliminated by pulling out the wire body in a direction in which the twist is returned once for each rotation. It can be supplied to the processing step in a non-twisted state. Furthermore, since the empty winding bobbin can be replaced without stopping the supply of the striated body, there is a great advantage that productivity is improved.
