Abstract

PROBLEM TO BE SOLVED: To provide a glass yarn winding machine which can wind around a conductor glass yarn which is not loosened, by lowering the friction resistance, when the glass yarn reeled out of yarn cheese passes by pillars. SOLUTION: A flyer 10, rotates about a conductor which is running at a given speed supports pillars 20, 21, 22 between a pair of rings 11, 12 and supports yarn cheese 60 on a bobbin 61. Rotation rollers 80, 81, 82 are fitted at the outside of one pillar. Since the rotation rollers 80, 81, 82 rotate by friction resistance with glass yarn 70, no changes occur in tensile strength of the glass yarn 70.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass yarn winding machine for winding glass yarn around a conductor.

[0002]

2. Description of the Related Art Glass yarn has excellent heat resistance, electrical characteristics,
Since it has chemical properties, the glass yarn winding in which the glass yarn is wound around the conductor wire is used as a heat resistant winding.

FIG. 4 is an explanatory view of a conventional glass yarn winding machine. FIG. 5: is explanatory drawing of the state which pays out a glass thread. The flyer 10 supports a plurality of columns 20, 21, 22 between a pair of rings 11 and 12, and a guide 30 having an annular portion that allows glass thread to pass through is attached to the ring 11. The guide mounting portion 25 is fixed to the column 21,
Guides 31 and 32 each having an annular portion through which the glass thread passes are attached to the guide attachment portion 25. 60
Is a thread cheese obtained by bundling thousands of glass fiber filaments into a glass thread, which is cross-wound on a bobbin 61. 40 is a pin and is a conductor 50.
Plays a role of a guide when the glass thread 70 is wound around the surface of the. The conductor 50 has an arrow S as the flyer 10 rotates.
Sent in the direction.

Glass thread 70 fed from thread cheese 60
Is divided into two after passing through the column 20, one glass thread passes through the annular portion of the guide 31 attached to the guide attachment portion 25, the other glass thread passes through the annular portion of the guide 32, and both glass threads are ringed. Guide 30 attached to 11
One glass thread is formed through the annular portion of and is wound around the surface of the conductor 50 via the pin 40 to form a glass thread winding 51.

The flyer 10 has a glass thread 70 on the conductor 50.
In order to wind, the conductor 50 rotates in the direction of arrow R about the conductor 50. At this time, since the bobbin 61 to which the thread cheese 60 is attached gives a constant tension to the glass thread 70 fed out each time the glass thread 70 is wound around the conductor 50,
The flyer 10 is urged in a direction opposite to the rotating direction.

[0006]

However, according to the conventional glass yarn winding machine, since the glass yarn fed from the yarn cheese passes through the fixed support, it is affected by frictional resistance and the glass yarn is not tensioned. There is a problem in that fluctuations occur, the glass yarns are scattered, and the appearance of the glass yarns after being wound around a conductor is irregularly disturbed, resulting in a defective product.

Therefore, an object of the present invention is to reduce the frictional resistance when the glass yarn fed from the yarn cheese passes through the support, and to wind the glass yarn without the looseness around the conductor. To provide.

[0008]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention feeds out a cheese cheese supported on a conductor running at a predetermined speed by a fryer rotating about the axis of the conductor. In a glass yarn winding machine that winds glass yarn, the flyer includes a support member that supports the yarn cheese, a pair of rings provided at both ends, a plurality of columns supported by the pair of rings, and the yarn. There is provided a glass yarn winding machine comprising: a rotating roller that supports and feeds the glass yarn fed from cheese; and a guide means that guides the glass yarn fed by the rotating roller onto the conductor.

Further, the glass yarn winding machine is characterized in that the rotating roller has a roller length longer than the width of the yarn cheese.

Further, there is provided a glass yarn winding machine characterized in that the rotating roller is constituted by one of the plurality of columns.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a glass yarn winding machine according to the present invention will be described.

FIG. 1 is a view showing a glass yarn winding machine of the present invention, and FIG. 2 is a schematic view of the flyer of FIG. 1 seen from the X direction,
FIG. 3 is an explanatory diagram of a state where the glass yarn is fed out. In the figure, the same reference numerals as those of the conventional example in FIG. 4 indicate the same parts as those of the conventional example. The structure is almost the same as that of the conventional example, but rotating rollers 80, 81, 82 are mounted between the rings 11, 12 on the outside of the support column 20 with which the glass thread 70 unwound from the thread cheese 60 first comes into contact. ing.

Glass thread 70 fed from thread cheese 60
Is bisected after passing through the rotating rollers 80, 81, 82 at the column 20, one side of which is a glass thread of the guide 31 attached to the guide attachment portion 25, and the other glass thread is of which the other side is a ring portion of the guide 32. After that, both glass yarns pass through the annular portion of the guide 30 attached to the ring 11 to form one glass yarn, and the conductor 50 is formed through the pin 20.
Wrap around the surface of.

Since the rotating rollers 80, 81, 82 rotate due to the contact resistance with the glass yarn 70, the tension of the glass yarn does not fluctuate.

Further, the rotating rollers 80, 81, 82 are designed so that the rotating roller length is longer than the thread cheese width. This prevents the glass yarn from hitting the end portion of the rotating roller and fluctuating in tension when the glass yarn is fed out from the vicinity of both ends in the width direction of the yarn cheese.

In the above invention, the rotating roller is arranged so that the glass yarn does not come into contact with the periphery of the supporting column with which the glass yarn delivered from the thread cheese comes into contact. However, instead of the rotating roller, the supporting column is rotatably attached. Thus, the same effect as above can be obtained.

[0017]

As described above, according to the glass yarn winding machine of the present invention, the glass yarn fed from the yarn cheese is supported by the rotating roller, so that the tension of the glass yarn does not fluctuate. It is possible to wind the glass thread which is not loosened around the conductor.
