Abstract

PURPOSE:To provide a twisting apparatus for embroidery thread capable of developing various colors and unified massive feeling, etc., by properly adjusting the rotational direction, rotational speed, tension, etc., of each element yarn. CONSTITUTION:A plurality of shafts 3a for holding element yarn bobbins are attached to one face of a rotary disk 1 parallel to the rotary axis 1a of the disk and a yarn-feeding through-hole 7 is opened at the center of the disk. Element yarn bobbins 3 wound with yarns having mutually different colors, thicknesses or materials are attached to the shaft 3a in a state rotatable on its own axis and a core yarn bobbin 5 is rotatably set via an attaching plate 4. Yarns delivered from the element yarn bobbins 3 and the core yarn bobbin 5 are collected together by a thread tension adjusting part 6, passed through the yarn-feeding hole 7 and guided to a rotating winding bobbin 8 through a driving shaft 16 and a variable speed shaft 17 driven by a motor 15. Various twisting works can be performed by arbitrarily setting the rotation of the disk- rotating shaft 1a and the element yarn bobbin holding shaft 3a and the tension of the yarn tension adjusting part 6.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embroidery thread twisting device for twisting raw threads 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 two unthreaded yarns in order to express delicate shades of plural colors. In this method, two bobbins of different colors are wound on the embroidery machine and inserted into the same needle hole of an embroidery needle from different bobbins.

[0003]

However, in the two-plying method, a difference occurs in the sliding condition of the raw thread due to the feed state of the raw thread of each embroidery machine. , There may be slack in the raw threads and unevenness in the finish may occur, or one strand may not be sewn because there is no twist, resulting in a large difference in the finish of the embroidery. There was a drawback that adjustment to eliminate the difference was difficult.

[0004]

An embroidery thread twisting device according to the present invention comprises a rotating disk having a yarn feeding hole formed at its center.
A bobbin, in which uncoated threads of different colors, thicknesses or materials are wound on one side of the rotating disk, is set so as to be rotatable about an axis parallel to the axis of rotation of the rotating disk. , A thread tension member that guides each element thread fed from each element thread bobbin set on the element thread bobbin mounting shaft by bundling the element threads from the thread supply hole to the opposite side of the rotating disk, and on the opposite side of the rotating disk. A winding bobbin mounting shaft for setting a winding bobbin capable of winding the plurality of derived raw yarns as a single yarn; rotation of the rotary shaft and the raw yarn bobbin mounting shaft; and the yarn tension member. The tension of can be set arbitrarily.

For the purpose of twisting the embroidery thread using the core thread, the core thread bobbin is set on the opposite side of the winding bobbin mounting axis with respect to the rotating disk of the embroidery thread twisting device. An embroidery thread centered on the core thread is provided by providing a shaft and a thread tension member that guides the core thread fed from the core thread bobbin together with the element thread from the insertion hole to the opposite side of the rotating disk. Obtainable.

[0005]

The embroidery thread twisting device having the above-described structure twists various embroidery threads by easily adjusting the rotation direction, the number of rotations or the rotation speed of the thread or the degree of pulling of the thread. Can be combined.

[0006]

1 is an explanatory view of an embroidery thread twisting device, and FIG. 2 is an enlarged view of a part thereof. Reference numeral 1 denotes a rotary disk rotatably provided on a machine frame 2, and a bobbin 3 wound with a raw thread is provided on one surface thereof in parallel with a rotary shaft 1a of the rotary disk 1 and a plurality of them are provided around the rotary shaft 1a. Since the unthreaded bobbin mounting shaft 3a is rotatably provided by a bearing, a plurality of unthreaded bobbins 3 and 3 wound with uncoated threads of different colors, thicknesses or materials are rotatably mounted on the rotating disk 1. ,
It is standing. A core thread bobbin 5 around which a core thread is wound is rotatably provided beside the rotary disk 1 via a mounting plate 4. Threads fed from the respective thread bobbins 3, 3 set on the thread bobbin mounting shaft and the core thread of the core thread bobbin 5 are bundled and guided from the thread supply hole 7 to the opposite side of the rotary disc 1. Rotating disk 1 through tone member 6
It is pulled downward from the yarn feeding hole 7 penetrating in the center of the. Further, on the opposite side of the rotating disk 1, the guide roller 8
A winding bobbin mounting shaft 9a for setting a winding bobbin that can be wound on the winding bobbin 9 as a single embroidery thread by using a plurality of raw yarns and core yarns drawn out from the yarn feeding hole 7 via ing. In FIG. 2 in which the rotary disk 1 is enlarged, 10 is a main shaft fixed to the machine frame 2, and the rotary disk 1 is fitted onto the rotary shaft 1a by a bearing 10a. At the center of the rotary 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. Reference numeral 11 denotes a gear that is fitted inside the rotary disk 1 by supporting the rotary shaft 1a with a bearing 11a and is fixed to the machine frame 2 by a mounting member 12, and is a lower end of the unthreaded bobbins 3 and 3. Mesh with the gears 3g, 3g provided on the. The gear 11 is linked by a belt to a speed change shaft 14 via an intermediate shaft 13, and the speed change shaft 14 has a motor 15
A belt is interlocked with a driving shaft 16 driven by. Further, the drive shaft 16 fixed to the machine frame 2 by the bearing 16 a is linked to the take-up bobbin 9 via a speed change shaft 17 by a belt.

Next, the operation of the embroidery thread twisting 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 raw yarn and the core yarn are wound. At the same time, the driving force is transmitted from the drive shaft 16 to the gear 11 via the speed change shaft 14, and the rotating disk 1 rotates.
The raw yarn bobbins 3 and 3 revolve around the yarn feeding hole 7 and the raw yarn is twisted around the core yarn. Further, the gears 3g, 3g provided on the opposite side of the rotary disc 1 are revolved by the rotary disc 1 with respect to the gear 11 fixed to the mounting member 12, so that the unthreaded bobbins 3, 3 rotate to rotate the core yarn. Twist is added to the yarn itself that is twisted around the.

This embroidery thread twisting device has a rotary shaft 1a.
Since the number of rotations, the speed and the direction of rotation of the unthreaded bobbin mounting shaft 5a and the tension of the thread tension member can be arbitrarily set, the tension or tension of the thread tension member 6 as well as the pulling speed can be easily adjusted. The embroidery thread can be easily created by combining different thicknesses and pulling tensions from thin embroidery thread to knitting string. The tension of thread pulling can be freely set by adjusting the rotary tension or by using an adjusting member such as a plate instead of the rotary tension. The thread drawing speed can be set by adjusting the gear ratios of various gears and the speed change shaft according to the characteristics of the raw thread.

[0009]

As described above, according to the present invention, the embroidery thread twisting device twists various embroidery threads by simply adjusting the rotation direction of the thread, the number of rotations and the degree of pulling of the thread. Unlike conventional techniques, the embroidery thread is always embroidered with a unified expression of textures derived from the subtle shades of multiple colors or the raw material and thickness of the raw thread itself. It can be provided to the machine, and the real benefit to the embroidery industry is enormous.
