DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embroidery thread aligning apparatus for binding and aligning elementary yarns having different materials, thicknesses, colors and tensile strengths.

[0002]

2. Description of the Related Art Conventionally, in embroidery crafts, there is a method of embroidering by taking, for example, two yarns in order to express subtle shades of a plurality of colors. In this method, two yarns are inserted into the same needle hole of an embroidery needle from separate bobbins around which yarns of different colors are wound, and the two yarns are sewn together.

[0003]

However, in the double picking method, since the slipping state of the yarns differs depending on the yarn feeding condition of each embroidery machine, a difference occurs in the amount of yarn sent or drawn. In some cases, sagging occurs in the yarn, resulting in irregularities in the finish, or because there is no twisting, one of the yarns may be stitch skipped, resulting in a large difference in the embroidery finish. However, there is a disadvantage that it is difficult to adjust to eliminate the difference.

[0004]

SUMMARY OF THE INVENTION An embroidery thread aligning apparatus according to the present invention comprises a rotating disk having a yarn feed hole formed at the center thereof, and one surface of the rotating disk having different colors, thicknesses or materials. Fine
A plurality of thread bobbin mounting axes for setting a bobbin on which a embroidery thread and a knitting cord are wound as filaments so as to be able to rotate around an axis parallel to the rotation axis of the rotating disk; A thread tension member that guides each of the yarns unwound from the set yarn bobbins from the yarn feeding hole to the opposite side of the rotating disk, and the plurality of derived yarns on the opposite side of the rotating disk. A take-up bobbin mounting shaft for setting a take-up bobbin capable of taking up the yarn as one yarn, wherein the rotation of the rotation shaft and the yarn bobbin mounting shaft and the tension of the yarn tension member are adjusted according to the characteristics of the yarn. It can be set arbitrarily.

For the purpose of aligning the embroidery thread using the core thread, the core thread bobbin for setting the core thread bobbin on the opposite side of the winding bobbin mounting axis with respect to the rotating disk of the embroidery thread alignment device. An embroidery thread centering on the core yarn by providing a mounting shaft and a yarn tension member for guiding the core yarn fed from the core yarn bobbin together with the element yarn from the insertion hole to the opposite side of the rotating disk together with the element yarn. Can be obtained.

[0006]

The embroidery thread pulling and aligning apparatus according to the above-described structure can easily adjust the rotation direction, the number of rotations or the rotation speed of the fine embroidery thread and the knitting cord, or the degree of the pulling of the elementary thread, so that various devices can be easily adjusted. Embroidery thread can be aligned.

[0007]

1 is an explanatory view of an embroidery thread pulling and aligning apparatus, and FIG. 2 is an enlarged view of a part of the apparatus. Reference numeral 1 denotes a rotating disk rotatably provided on a machine frame 2, and a bobbin 3 on which a thread is wound on one surface thereof is provided with a rotating shaft 1 of the rotating disk 1.
Since a plurality of yarn bobbin mounting shafts 3a are provided so as to be able to rotate by bearings in parallel with and around the shaft thereof, yarns of different colors, thicknesses or materials are wound on the rotating disk 1. A plurality of bobbins 3, 3
It is standing. A core yarn bobbin 5 around which a core yarn is wound via a mounting plate 4 is rotatably provided beside the rotary disk 1. The yarns fed from the yarn bobbins 3 and 3 set on the yarn bobbin mounting shaft and the core yarn of the core yarn bobbin 5 are bundled and guided from the yarn feeding hole 7 to the opposite side of the rotary disk 1. The rotating disk 1 is provided via the tone member 6.
Is pulled downward from a yarn feeding hole 7 penetrating through the center of the hole. Further, on the opposite side of the rotating disk 1, guide rollers 8
And a take-up bobbin mounting shaft 9a for setting a take-up bobbin that can be taken up on the take-up bobbin 9 as a single embroidery thread using a plurality of element yarns and core yarns led out of the yarn feeding hole 7 through ing. In FIG. 2 in which the rotating disk 1 is enlarged, reference numeral 10 denotes a main shaft fixed to the machine frame 2, and the rotating disk 1 is externally fitted with the rotating shaft 1a supported by a bearing 10a. At the center of the rotating disk 1 and the main shaft 1, there is provided a yarn feeding hole 7 through which the raw yarn and the core yarn are inserted downward. Reference numeral 11 denotes a gear fixed to the machine frame 2 by a mounting member 12 while the rotating disk 1 is supported by the rotating shaft 1a by a bearing 11a, and is a lower end of the yarn bobbins 3, 3. Gears 3g, 3g provided in the gears. The gear 11 is linked to a speed change shaft 14 via an intermediate shaft 13 by a belt.
Is linked to a driving shaft 16 driven by a belt. The drive shaft 16 fixed to the machine frame 2 by the bearing 16a is linked to the winding bobbin 9 via a speed change shaft 17 by a belt.

Next, the operation of the embroidery thread aligning device will be described. The driving force is transmitted from the driving shaft 16 driven by the motor 15 to the winding bobbin 8 via the speed change shaft 17, so that the element yarn and the core yarn are wound. At the same time, the driving force is also transmitted from the driving shaft 16 to the gear 11 via the speed change shaft 14, and the rotating disk 1 rotates. The raw yarn is twisted around the yarn. Also, the gears 3g, 3g provided on the opposite side of the rotating disk 1 are revolved by the rotating disk 1 with respect to the gear 11 fixed to the mounting member 12, so that the yarn bobbins 3, 3 rotate by themselves and slightly rotate. Are twisted together and sent out.

This embroidery thread aligning device can arbitrarily set the number of times, speed and direction of rotation of the rotating shaft 1a and the yarn bobbin mounting shaft 5a, and the tension of the thread tension member. The pulling speed can be easily adjusted together with the pulling tension or the pulling force, and the embroidery thread can be easily formed by combining different thicknesses and pulling tensions from a thin embroidery thread to a braid. The tension of the stringing can be freely set by adjusting the rotary tension or by using an adjusting member such as a plate instead of the rotary tension. Further, the yarn drawing speed can be set by adjusting the gear ratios of various gears and the transmission shaft according to the characteristics of the yarn.

[0010]

As described above, the embroidery thread aligning device according to the present invention draws various embroidery threads by simply adjusting the rotation direction, the number of rotations, and the degree of pulling of the thread. Unlike the two-strand method as in the prior art, the embroidery machine can always embroider threads that unify the subtle shades of multiple colors or the expression of the texture derived from the material and thickness of the yarn itself. Can be provided to the embroidery industry, and the benefits are enormous.
