Description

Description: FIELD OF THE INVENTION The present invention relates to a wire winding device, and more particularly to a wire winding device provided with a means for processing an inner terminal at the beginning of winding.

[Conventional technology]

2. Description of the Related Art Conventionally, the following two methods have been used as a method for automatically starting the winding of a wire, that is, fixing an inner end in a winding process in a wire winding device.

(1) Method of fixing the inner terminal to the winding bobbin body with the adhesive tape At the beginning of winding the wire, press the adhesive surface of the adhesive tape supplied simultaneously from above the wire passed over the body of the winding bobbin. And fix it by gluing it to the body of the take-up bobbin,
The excess wire material at the terminal portion is cut by an automatic nipper or the like, the winding bobbin is further rotated by a predetermined angle, the tape is adhered to the body of the winding bobbin by a predetermined length, and then the excess tape is cut.

(2) Using a traverser pulley to guide the wire, the wire is passed from the outside of the bobbin to the body, and the wire is wrapped around the bobbin and fixed. The inner end of the wire outside the collar of the take-up bobbin is temporarily fixed. Then, the traverser pulley is moved from the outside of the collar to the body to start winding while passing the wire from the outside of the collar to the body. After the wire is wound up to two or more layers or until it is fully wound and the inner end of the wire is completely fixed, the terminal temporarily fixed to the outside of the brim is opened. If necessary, disconnect the inner terminal that has come out of the collar.

[Problems to be solved by the invention]

However, in the method of fixing the inner terminal to the bobbin body with the adhesive tape, when the wound wire is used, the wire of the inner terminal adhered to the bobbin cannot be used. Also, the adhesive of the adhesive tape may adhere to the surface of the wire. Depending on the type of the adhesive tape and the wire, there is a possibility that the quality of the wire is changed due to chemical change on the surface.

However, in the method in which the wire is passed from the outside of the bobbin to the body, the inner terminal comes out of the end of the wound bobbin, so that the inner terminal becomes an obstacle when using the wound wire. . In some cases, it cannot be used as a wire for the inner terminal.

Therefore, an object of the present invention is to use the wire material of the inner end portion when using the wound wire material, and to automatically use the inner wire during the winding process so that the inner terminal does not interfere. It is an object of the present invention to provide a wire winding device having a simple configuration capable of fixing a terminal.

Another object of the present invention is to provide a wire winding device having a simple structure in which an inner terminal can be automatically fixed in a winding process without using an adhesive tape which causes contamination or quality deterioration of a wire surface. It is to provide a device.

[Means for solving the problem]

A winding bobbin for winding a wire rod; a rotating arm rotatably supported on the same axis as a winding axis of the winding bobbin, and having a length greater than a radius of a flange of the winding bobbin; A wire clamp attached to the position of the large length of the rotary arm so as not to contact the body of the bobbin and capturing an inner end of the wire; and a winding bobbin and the rotary arm on the winding shaft. Rotating means for rotating the wire arm in parallel with the winding shaft, thereby moving the wire clamp between the inside and outside of the collar of the winding bobbin in parallel with the winding shaft. Means for cutting the wire rod between the body of the winding bobbin and the wire rod with the inner end of the wire rod captured by the wire rod clamp; To capture said terminal wire in the wire clamp,
By positioning the wire clamp outside the collar of the winding bobbin by the moving means, and rotating the winding bobbin, the rotating arm, and the wire clamp on the winding shaft by the rotating means, After connecting the wire following the inner terminal to the body of the winding bobbin, the wire is wound around the body for a predetermined number of turns, and the first turn of the wire following the inner terminal is formed thereafter. When the wire clamp is fixed by the turn, the wire clamp is moved by the moving means to the inside of the collar of the winding bobbin, and the wire is moved by the cutter between the wire clamp and the body of the winding bobbin. A wire winding device, characterized in that the wire rod is cut by a wire.

[Action]

The wire winding device of the present invention may be configured to rotate only the winding bobbin, or the winding bobbin may be fixed, and wire guide means that rotates around the winding bobbin, such as a movable guide pulley, may be used. May be sowed and wound around a bobbin.

After the wire end is captured by the wire capturing means, the wire capturing means is wound in the axial direction, and the traverser pulley is positioned inside the collar outside the collar of the bobbin (the end of the winding range if there is no collar). Is wound along the body of the take-up bobbin, the wire passing between them is wound obliquely with respect to the circumference of the take-up bobbin. In this state, when the winding is performed while simultaneously rotating the wire capturing means and the winding bobbin, and moving the traverser pulley closer to the collar,
The wire near the inner end wound obliquely around the bobbin forms a twill with the wire wound thereon and is almost fixed. Thereafter, the wire catching means is moved axially inside the collar of the bobbin, and the surplus wire near the terminal is cut and removed by the cutting means of the later operation. The subsequent winding of the wire is performed while the traverser pulley is axially moved at a predetermined direction and speed while rotating the winding bobbin as usual.

The wire capturing means captures the vicinity of the end of the wire by, for example, pinching it. It is preferable to operate by a cylinder driven by air, hydraulic pressure, water pressure, or the like, or a solenoid driven by electromagnetic force or the like so that the air can be automatically captured.

In the wire winding device of the present invention, after the inner end is fixed by the formation of the stitches, the excess wire extending from the stitch formation portion to the outside of the winding is removed. This is because excess wire protruding outside the winding often hinders use of the wound wire. For example, a wire passing between the wire catching means and the winding bobbin is cut at a position close to the winding bobbin by a suitable cutting means, for example, an automatic cutter. It is preferable that the cutting means can be moved to a position that does not hinder winding, except when used for cutting.
