きる弾性糸の紡糸巻取機に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elastic yarn take-up winder capable of alternately winding an elastic yarn such as polyurethane with two bobbin holders and switching the continuously running elastic yarn from a full bobbin to an empty bobbin. Regarding

た構造である。2. Description of the Related Art First, the basic structure of an elastic yarn take-up winder will be described with reference to FIG. The take-up winder has a structure in which a machine frame 7 is provided with a vertically movable lifting box 1 and a rotatable turret 2.

ースを行っている。The elevator box 1 has a touch roller 3,
The traverse devices 4 are respectively supported, and the touch roller 3 is constantly in pressure contact with the yarn layer of the bobbin B at the winding position, which will be described later, and rotationally drives the bobbin B counterclockwise. Further, the traverse device 4 is provided with a traverse guide 6, and the traverse guide 6 engages with the yarn Y and reciprocates in the traverse range to traverse the yarn Y.

ボビンホルダ１５は巻取位置ａに、他方のスピンドル１
６は待機位置ｂに位置している。The turret 2 is rotatable about a rotary shaft 14 by a spindle (not shown) and is driven by an induction motor 17. Then, the two bobbin holders 15 and 16
Are rotatably supported by the turret 2,
Several bobbins B (only two are shown in the figure for simplification) are inserted and attached to the respective bobbin holders 15 and 16, and one bobbin holder 15 is at the winding position a and the other spindle 1
6 is located at the standby position b.

への糸の切り換えは終了する。The turret 2 rotates 180 degrees when the yarn Y is fully wound on the bobbin B at the winding position a, switches the positions of the bobbin holders 15 and 16, and the full bobbin B moves to the standby position b and the empty bobbin B. Is newly positioned at the winding position b. However, at the time when each bobbin B is located at the new position, the supplied yarn Y is still in the standby position b and the full bobbin B
The empty bobbin B catches the yarn Y, cuts the yarn, and starts winding to start the full bobbin B to the empty bobbin B.
The switching of the yarn to is completed.

く。Normal yarn Y such as nylon and polyester
Is carried to a slit (not shown) provided on the bobbin B, the bite bites into the slit and is captured, and the yarn Y is cut by the tension due to the rotation of the empty bobbin B and wound around the empty bobbin.

滑るという現象が生じ、糸渡しが失敗する。[0007] However, if an elastic thread such as polyurethane is tried to be cut into the slits, switching failures frequently occur. The elastic thread extends like a rubber thread and has a smaller cross-sectional area. Therefore, after cutting into the slit,
A phenomenon occurs in which the empty bobbin B is stretched by being pulled to be stretched, the cross-sectional shape is reduced, the slit is released and slips, and thread passing fails.

する。Therefore, the thread passing method as shown in FIG. 8 is applied to the elastic thread. A resin coating is applied to the surface of the empty bobbin B so that the elastic thread can easily stick to the surface. Further, the rotation direction of the turret 2 is set to the counterclockwise direction opposite to the normal direction, and the relationship between the empty bobbin B and the yarn Y is changed from reverse to forward. Further, a sudden braking device is attached to the spindle (not shown) for the bobbin holder 16 of the full bobbin B at the standby position.

く。このようにして、弾性糸Ｙの摩擦係数が大きく、く
っつきやすいという性質を利用して糸渡しする。When switching from the full bobbin B to the empty bobbin B, the turret 2 is rotated in the direction shown. The elastic yarn Y runs in a state of being pressed against the surface of the empty bobbin B, and becomes a trajectory that leaves the empty bobbin B and reaches the full bobbin B. The surface of the empty bobbin B is resin coated,
The elastic yarn Y sticks to the surface of the empty bobbin B, is peeled off, and is wound around the full bobbin B. In this state, the bobbin holder 16 of the full bobbin B is rapidly decelerated (the bobbin holder 15 of the empty bobbin B is rotating normally). Then, the elastic yarn Y between the empty bobbin B and the full bobbin B is loosened. However, since the elastic yarn Y sticks to the surface of the empty bobbin B, the elastic yarn Y is attracted to the empty bobbin B as shown by the dotted line, and when the elastic yarn Y makes one rotation around the empty bobbin B, the elastic yarn Y becomes It cuts between the empty bobbin B and the full bobbin B and winds around the empty bobbin B. In this way, the elastic yarn Y has a large coefficient of friction and is easily attached to the elastic yarn Y so that the yarn is passed.

上述の糸渡し方法では糸渡しに失敗する。However, in the above-mentioned yarn passing method, it is necessary to rapidly decelerate the bobbin holder 16 on the full bobbin B side at the time of yarn passing.
When a brake having a large inertial weight such as the full bobbin B is suddenly braked, the electric brake of the motor is not sufficient, and a large-scale mechanical brake device needs to be provided on the spindle, which complicates the structure. There was a problem. In addition, there is a problem in that the thick elastic yarn is liable to loosen because the adhesive force does not increase in comparison with the force to move away from the empty bobbin by the inertial force, and the yarn passing failure may occur due to the slack. Further, even when the adhesive force of the elastic yarn is small and the holding force of the yarn by the surface of the bobbin is small, or when the elastic yarn is too thick to enter the slit formed in the bobbin, the yarn passing method fails.

An object of the present invention is to provide a spinning winding method and a spinning winding machine.

In this case, the bobbin holder is turned over and the elastic yarn spinning winder that switches the elastic yarn to the empty bobbin at the standby position is provided with a means for winding the elastic yarn traveling through the empty bobbin to the full bobbin around the empty bobbin at the time of the switching. The winding means is provided with means for imparting running resistance to the elastic yarn (hereinafter referred to as yarn running resistance imparting means).
【００１３】また、前記空ボビンを巻取位置を過ぎた中

き付けられて切断され、糸渡しが行われる。When the elastic yarn traveling through the empty bobbin to the full-winding bobbin is wound around the empty bobbin while the running resistance is applied to the empty bobbin at the time of switching, the yarn on the upstream side of the yarn running resistance applying means can be loosened. Even if the elastic thread stuck to the bobbin has a small adhesive force, it is wound around the empty bobbin without being peeled off and cut, and thread passing is performed.

にこれを行うことができる。Further, if the elastic yarn is switched at an intermediate position after the winding position, the initial winding angle of the elastic yarn on the empty bobbin becomes large, and the yarn is hard to loosen, so that the yarn passing is easier. In addition, the required rotation angle of the winding means is reduced, and the device is simplified. Further, when the frictional body is brought into contact with the yarn or the yarn is bent to impart running resistance, this can be easily performed.

Then, the elastic yarn Y2 from the empty bobbin B to the full bobbin B is guided by the guide bar 33 and is forcibly wound around the empty bobbin B. At the same time, the elevating box 1 rises, the touch roller 3 separates from the empty bobbin B, and an aerial yarn path of the elastic yarn Y entering the empty bobbin B is formed. Further, the peripheral speed of the empty bobbin B is increased by 0 to 50%, and the elastic yarn Y2 reaching the empty bobbin B through the touch roller 3 is reached.
Increase the tension of.

が完了する。At this time, the friction between the guide bar 33 and the elastic yarn Y imparts a running resistance to the elastic yarn Y, and the elastic yarn Y on the upstream side of the guide bar 33 can be loosened. Even if the thread has a small adhesive force, the thread is wound around the empty bobbin B without being peeled off. When the revolving arm 32 further rotates in the direction of the arrow 38, the elastic yarn Y2 and the reciprocating elastic yarn Y1 come into contact with each other. When the elastic yarn Y1 and the elastic yarn Y2 come into contact with each other, they are entangled with each other because they are sticky elastic yarns. At this time, the elastic yarn Y2
Is slackened, it is easily entangled, and the elastic yarn Y2 extending from the empty bobbin B to the full bobbin B is wound around the empty bobbin B together with the elastic yarn Y1 entering the empty bobbin B. Then, the elastic yarn Y2 continues to be stretched, and eventually breaks to complete the yarn passing.
