Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a yarn winding device,

The present invention relates to a yarn winding device capable of adjusting the winding angle.

Generally, in winding a yarn, an important factor for determining the shape of the yarn is the winding width by the traverse device. The winding shape varies depending on the wide and narrow winding width, and it is wound in various shapes such as a cheese shape and a conical shape in accordance with the necessity of a post-process.

The wide and narrow width of the winding width is basically determined by the traverse device, and the traverse device is variously presented by a method using a cam device, a method using a wing device, and the like. The winding width determined by the traverse device can be classified into a constant winding width, a winding width that fluctuates periodically, and a winding width that fluctuates in some cases.

As described above, the adjustment of the winding width not only makes the winding shape good, but also eliminates defects in the marine process in which the yarn is loosened in the subsequent process, and enables winding various kinds of yarns with good quality. In addition, these width adjustment methods can improve the bulge and the bulge which are important in the wound shape, and thereby, it is possible to produce a cake having a good shape and eliminating defects in the post-process.

The present invention relates to a yarn winding device capable of adjusting the yarn winding angle by adjusting the yarn winding angle of the yarn from the traverse guide to the bobbin so as to prevent development, bulge phenomenon, lateral irregularity and ribbon phenomenon, to provide.

A yarn winding device capable of adjusting the winding angle according to the present invention includes a traverse unit having a traverse guide for traversing a yarn fed to a bobbin in a lateral direction and a speed control unit for controlling a moving speed of the traverse guide; A pressure roller which is positioned below the traverse portion and guides the yarn to the bobbin and presses the bobbin; And a bobbin holder located at a lower portion of the pressure roller and coupled to the bobbin, wherein the speed control unit controls a moving speed of the traverse guide to adjust a winding angle of the yarn wound around the bobbin from the traverse guide .

When the speed control unit speeds up the traverse guide, the winding angle of the yarn wound on the bobbin decreases, and when the speed control unit slows down the moving speed of the traverse guide, the winding angle decreases The width of the yarn wound on the bobbin can be increased.

The winding angle may be adjusted by varying the length of time the yarn is wound on the bobbin, and may be determined by adding the first and second auxiliary patterns to the basic pattern.

In addition, the first auxiliary pattern may be repeated with the period in which the perspiration angle rises from 0 to the target perspiration angle during the first time and then falls to zero.

Also, the first auxiliary pattern may be maintained at the target winding angle for a predetermined time.

In addition, the period of the first auxiliary pattern may vary with time.

Further, the target winding angle of the first auxiliary pattern may vary with time.

Also, the shape of the second auxiliary pattern may be continuously repeated from the first decimation angle to the second decimation angle with the decimation angle of 0 as the center.

The yarn tensioning device capable of adjusting the winding angle according to an embodiment of the present invention can control the winding speed of the yarn from the traverse guide to the bobbin by controlling the moving speed of the traverse guide.

Here, parts having similar configurations and operations throughout the specification are denoted by the same reference numerals.

Fig. 3 is a view showing the magnitude of the traverse guide moving width and the winding angle depending on the winding width of the yarn wound on the bobbin. 4 is a graph showing the relationship between the winding angle and the winding width.

1 and 2, a yarn winding device 100 according to an embodiment of the present invention includes a traverse unit 110, a pressure roller 120, and a bobbin holder 130. The yarn winding device 100 capable of adjusting the winding angle according to an embodiment of the present invention is a device for winding yarn on a bobbin 131 coupled to a bobbin holder 130.

The traverse unit 110 has a traverse guide 111 for traversing the yarn supplied to the bobbin 131 in the traverse direction and a speed control unit 112 for controlling the traveling speed of the traverse guide 111. When the traverse guide 111 reciprocates in the transverse direction, the yarn is wound on the bobbin 131 with a predetermined width. 3, the traverse width in which the traverse guide 111 reciprocates is different from the actual winding width of the yarn wound around the bobbin 131. As shown in Fig. This is because the traverse width varies depending on the helix angle (A) and the decay rate while the actual yarn is transferred to the winding width of the bobbin 131 wound with the yarn. Here, the decay rate is determined by a function of the inertia and tension of the yarn, the size of the free field, the frictional force of the portion in contact with the yarn, and the contact pressure. In the present invention, it is assumed that the decay rate is constant. The warp angle A is an angle at which the yarn is wound on the bobbin 131 due to the reciprocating motion of the traverse guide 111. [ Concretely, the warp angle A is an angle formed by the linear velocity of the outer diameter of the cake and the lateral velocity of the traverse guide.

The speed control unit 112 controls the moving speed of the traverse guide 111. Here, the moving speed of the traverse guide 111 affects the decoupling angle A. When the speed control unit 112 increases the moving speed of the traverse guide 111 and the decelerating angle A becomes larger and when the speed controlling unit 112 slows the moving speed of the traverse guide 111, Lt; / RTI > At this time, it is assumed that the traverse width at which the traverse guide 111 reciprocates is fixed. In addition, the winding angle A affects the winding width of the yarn wound on the bobbin 131. In Fig. 3, when the damping rate is constant, the winding angle of the yarn wound on the bobbin 131 and the winding angle A are inversely proportional to each other, as shown in Fig. That is, when the winding angle A becomes larger, the width of the yarn wound on the bobbin 131 decreases, and when the winding angle A becomes smaller, the width of the yarn wound on the bobbin 131 increases. As a result, the speed control unit 112 controls the moving speed of the traverse guide 111, thereby adjusting the width of the yarn wound on the bobbin 131.

The pressure roller 120 is positioned below the traverse unit 110 and guides the yarn fed through the traverse unit 110 to the bobbin 131. [ The pressing roller 120 is positioned above the bobbin holder 130 and presses the bobbin 131 when the yarn is wound on the bobbin 131 to stably wind the yarn on the bobbin 131 It plays a role. The pressing roller 120 contacts the bobbin 131 and presses the bobbin 131 while rotating the bobbin 131 while the yarn is wound.

The bobbin holder 130 is positioned below the pressing roller 120 and supports the bobbin 131 on which the yarn is wound. That is, the bobbin holder 130 is coupled to the bobbin 131. As the bobbin holder 130 rotates at a predetermined speed by a motor or the like, a yarn is wound on the bobbin 131.

The operation of the yarn winding device 100 having the above-described structure will be briefly described as follows.

The yarn is wound on the bobbin 131 by being coupled to the bobbin 131 provided on the bobbin holder 130. At this time, the yarn is reciprocated in the transverse direction by the traverse guide 111 of the traverse unit 110, so that the yarn is wound on the bobbin 131 with a predetermined width. The speed control unit 112 controls the moving speed of the traverse guide 111 to adjust the width of the yarn wound on the bobbin 131. Of course, the pressing roller 120 presses the bobbin 131 with a certain force so that the yarn is closely wound on the bobbin 131. The rotational speed of the bobbin holder 130 and the pressing roller 120 is controlled by a speed sensor (not shown).

On the other hand, since the yarn has a relatively long time to stay at both ends of the bobbin 131 when the operation direction of the traverse guide 111 is changed, the winding thickness of both ends of the bobbin 131 becomes relatively thick saddle phenomenon may occur. In addition, the yarn may cause a bulge phenomenon that flares to the side due to a change in the winding width or the shrinkage force of the wound yarn in the process of being wound on the bobbin 131, a lateral convexity phenomenon And a ribbon phenomenon in which the yarn is repeatedly wound at the same position.

Therefore, the yarn winding device 100 according to the present invention adjusts the winding width of the yarn wound around the bobbin 131 by adjusting the winding angle A by controlling the speed of the traverse guide 111, , Side irregularity phenomenon and ribbon phenomenon can be prevented. Therefore, the shape of the cake formed on the bobbin 131 is formed to be excellent. Here, the cake refers to a state in which the yarn is wound on the bobbin 131. [ As a result, the tension of the yarn becomes constant at the time of yarn production for producing various fabrics, so that a post-process such as dyeing can be performed smoothly.

Next, a specific method for adjusting the winding angle of the yarn winding device to improve the quality of the cake will be described.

5A to 5D are graphs showing patterns for determining the size of the winding angle according to the winding time of the yarn. FIG. 6 is a graph showing another embodiment of the first auxiliary pattern shown in FIG. 5B. The user determines the size of the winding angle A according to the winding time of the yarn and inputs the size of the winding angle A to the speed control unit 112. The speed control unit 112 adjusts the traverse guide 111). In the present invention, the size of the winding angle (A) with respect to the winding time is determined by adding the first auxiliary pattern and the second auxiliary pattern to the basic pattern.

As shown in FIG. 5A, the user decides a basic pattern by determining the size of the declining angle A with time. For example, the basic pattern is divided into a first section S1, a second section S2 and a third section S3 according to the winding time of the yarn. The slope angle A has a first slope a1 in the first section S1 and a second slope a2 in the second section S2 and a third slope a2 in the third section S3, a3). In the first section S1, the decoupling angle A is set so as to have a first inclination a1 so as to reach the reference decoupling angle AS and gradually increase. Also, in the second section S2, the decoupling angle A is set to maintain the reference decoupling angle A0. That is, the second slope a2 is set to zero. Next, in the third interval S3, the declination angle A is set to be smaller than the third declination angle a3 in the reference declination angle AS. Here, the absolute value of the first slope a1 is set to be larger than the absolute value of the third slope a3 (| a1 |> | a3 |). As described above, according to the present invention, it is possible to prevent the basic bulge phenomenon of the cake by setting different slopes of the wrapping angle (A) according to the section in which the yarn is wound. Of course, the winding angle A can be set to be constant regardless of the section in which the yarn is wound. However, in order to prevent the bulge phenomenon, it is preferable to set the slope of the winding angle A differently depending on the section in which the yarn is wound. In addition, the basic pattern is not limited to the above, but may be formed in other forms.

Next, as shown in FIG. 5B, the user determines a first auxiliary pattern. The first auxiliary pattern is a pattern in which the decoupling angle A is increased from 0 to the target decoupling angle AG and then decreased to 0 again for the first time t1. Here, the first auxiliary pattern may be maintained at a target declining angle AG for a predetermined time, and may be reduced to zero. The period of the first auxiliary pattern may be set periodically or non-periodically. That is, the period of the first auxiliary pattern may vary with time. Here, the first time (t1) when the declining angle A rises to the target declining angle (AG) and then descends determines the winding density at which the yarn is wound in a section where the winding width is narrowed. Therefore, the present invention can alleviate the side surface irregularity phenomenon in which the side surface protrudes or finely collapses during winding by adjusting the winding density. In addition, the present invention can prevent the phenomenon by repeating the first auxiliary pattern.

On the other hand, the target declination angle AG of the first auxiliary pattern is set to a target value fixed type having a fixed value (refer to FIG. 6A), or a target value ratio type which is increased by a constant value X in the basic pattern (See Fig. 6 (b)), or may be set to a target value arbitrary set type having an arbitrary value (see Fig. 6 (c)). That is, the target value ratio type or the target value arbitrary set type is set such that the target decoupling angle AG varies with time.

Next, as shown in FIG. 5C, the user determines a second assist pattern. The second auxiliary pattern is a pattern in which the decoupling angle A rises from the first decoupling angle A1 to the second decoupling angle A2 with 0 being the center, and then the decline angle is continuously repeated. At this time, the second time t2, which varies from the first declination angle A1 to the second declination angle A2, may be a relatively short time compared to the first time t1. Of course, if the first time t1 is less than or equal to the second time t2, the second auxiliary pattern may be omitted at the time when the first auxiliary pattern is formed. Such a second auxiliary pattern serves to prevent ribbon phenomenon which is repeatedly wound at the same position by imparting a lot of variation to the winding angle. In addition, when the second auxiliary pattern is used together with the first auxiliary pattern, the effect of preventing the ribbon is further improved.

Finally, in the yarn winding device 100 capable of adjusting the winding angle according to an embodiment of the present invention, the size of the winding angle according to the winding time of the yarn is determined by the sum of the first auxiliary pattern and the second auxiliary pattern, As shown in FIG.

As described above, the present invention is not limited to the above-described embodiment, but may be applied to a yarn winding device capable of adjusting the yarn winding angle according to the present invention. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
