DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ply-twisting device for forming a highly functional yarn such as a weft for weaving, a warp or a sewing yarn by plying raw yarns having different physical properties from each other and having various excellent functions. The present invention relates to a ply-twisting system in which the structure has been revolutionarily additionally modified so that

[0002]

2. Description of the Related Art Generally, in order to produce a functional yarn, for example, a yarn having a good feel and strength, a silk yarn having a good feel is twisted with a poly yarn having a good strength to form one yarn. To be used for weaving or other purposes. Hereinafter, a conventional ply-twisting machine for ply-twisting yarns having different physical properties will be described.

FIG. 1 is a side view showing the structure of a conventional plying machine. As shown in the figure, a predetermined number of raw yarn loading bases 2 are fixedly mounted on a rotary table 1 rotatably installed by a motor 400 so that they cannot rotate, and the raw yarns are directly above the center of the rotary table 1. Tension controller 3, transfer roller
4, the traverse guide 5, the winding cylinder 6, etc. are installed, and each yarn 300 with different physical properties mounted on the yarn loading base 2 is twisted by the tension adjuster 3 by the rotation of the rotary table 1. The winding yarn is wound around the winding cylinder 6 via the transfer roller 4 and the traverse guide 5, and the wound twisted yarn is set with another sizing agent supply device (not shown) and a heating device ( Finally, it is wound on a winding cylinder through a jumbo winder (not shown) through a winding cylinder (not shown).

[0004]

Various problems of such a conventional ply-twisting machine will be described below. FIG.
[Fig. 4] is a plied state diagram of a plied yarn.

Since only the rotary table 1 is rotated and the raw yarn loading base 2 is not rotated, when the original yarns 300 are twisted together, the original yarns 300 are not twisted by themselves. 6
As shown in (A), since only the original yarns are twisted together in a spiral entangled form, the degree of binding between the original yarns is very low, which causes a snarling phenomenon immediately after the twisting and the strength of the yarns. In addition, the tactile sensation is lowered, and the ply-twisted state is relaxed, which may cause interference in the loom during weaving, which lowers the weaving efficiency.

In many cases, the twisted state is not perfect and a separate twisting process is required, resulting in a decrease in productivity due to the addition of steps.

◎ Since each yarn is twisted without twisting itself, when the difference in the physical properties is large, the diameter of the weak yarn is changed due to the difference in the draw ratio, and the durability of the yarn is improved. Due to the problem of deterioration, it is the actual situation that yarn types with similar physical properties are mainly twisted together, so the range of yarn types is narrow and the function as a twisting machine cannot be exhibited, which makes it wider. This makes it impossible to produce a function of plied yarn and exposes the unevenness of function.

Since the structure has only a ply-twisting function, the ply-twisted yarn which has been ply-twisted goes through a separately installed sizing agent supply device, heating device and winding structure. In other words, since it is necessary to equip a large number of separate devices for the post-process of the plied yarn, not only is it expensive to purchase equipment,
There is a large financial burden on purchasing a factory site due to excessive space for installing this, and a lot of manpower is required to manage and operate it, which increases personnel costs and often causes work accidents. As a result, the cost of fiber production is increased, the competitiveness is reduced, and it is necessary to go through each of the above steps in different stages that are not continuous. The work of pulling out the finished work one by one and connecting it to the next process is very troublesome, and it takes a great amount of time and manpower, resulting in an extremely low productivity.

In addition, since each device consumes electric power separately, a large amount of power is wasted, which causes an increase in production cost.

In view of the above problems of the existing ply-twisting machine structure, the present invention enables double-twisting and eliminates the need for a separate post-process. A twisting table is installed in the center of the twisting table to install a spindle for mounting the bobbin that is located radially and allows the twisting of each thread to occur due to the rotation of the spindle. By rotating the table, each of the original yarns that have been twisted is secondarily plied, and the plied yarn that has completed plying is not immediately wound because it undergoes the post-process, so that one machine device is used. In order to complete all the post-processes in a series, the composite twisting system with a comprehensive function is a single device by connecting a glue supply device, heating device, and winding structure on top of the twisting device. The purpose is to provide.

Further, according to the present invention, it is impossible to perform twisting with a conventional twisting machine, and by providing a double twisting function to the original yarns having different physical properties, a stronger binding force is given, the snare ring phenomenon is prevented, the stretching ratio and the cross section are increased. The purpose of the present invention is to make it possible to produce a variety of epoch-making highly functional new synthetic yarns by imparting excellent weaving property by reducing the width of deformation of shape.

[0012]

According to the present invention for achieving the above object, a twisting table (Twisting Table) installed so as to be rotatable by a driving force of a motor of a plying machine.
By installing a multi-stage spindle drive pulley that is rotated separately from the table in the center of the table, the spindle drive pulley and the driven pulley of the thread mounting spindle fixedly installed in the twisting are linked by a belt. ,
Before the original yarn is twisted, the twisted yarn is secondarily twisted at the same time as the yarn in a state where the twist is imparted by itself, and the twisted yarn is made into a double twisted state.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described below in detail with reference to the accompanying drawings of an embodiment. FIG. 2 is a side sectional view showing the overall configuration of an embodiment of the ply twisting system of the present invention. FIG.

FIG. 4 is a sectional view of a twisting table in the embodiment of the ply twisting system of the present invention.

The driven pulley 11 of the twisting table 10 installed on the support frame 600 and the first pulley 401 of the motor 400 are connected to each other by a table drive belt 500 so as to be rotatable. In the center, the driven pulley 32 at the lower end and the second pulley 4 of the motor 400
A spindle drive pulley 30 having a predetermined number of pulley grooves 31 is installed in a state where the 02 and the twisting table 10 are connected to each other so as to be rotated separately from the twisting table 10. A predetermined number of spindles 20 having a large number of pulley grooves 21 are installed rotatably in a radial position around a spindle drive pulley 30, and the pulley grooves 21 are connected to a spindle drive pulley 30 using a spindle belt 502. Then, the rotational force of the spindle drive pulley 30 is simultaneously transmitted to each spindle 20, so that the original yarn mounted on the spindle 20 is imparted with a twisted state.

Immediately above the spindle 20, the tension of the raw yarn 300 that is unwound from the bobbin is adjusted so that the feed rate of the raw yarn 300 and the number of twists of the raw yarn 300 can be appropriately changed. The adjusting device 40 is installed.

The raw yarn tension adjusting device 40 is rotatably provided above the upper and lower raw yarn guide tools 42 and 47 fixed to the upper and lower ends of a fixed plate 41 and directly above the lower raw yarn guide tool 47. Guide roller 43
And a tension adjusting roller 45 that is selectively moved and fixed by being inserted into the arc-shaped movement guide hole 44, and the tension adjusting roller 45 is provided with a position fixing means 46, and the corresponding physical property. It has a function of adjusting the tension so that the optimum twisting is performed in consideration of the physical properties of the other original yarns twisted together.

On the other hand, immediately above the spindle drive pulley 30, a twisting guide ring 50 for fixing a predetermined number of raw yarns to which a twisted state is attached at one point to guide twisting is fixed. Install in the state.

An arcuate movement guide hole 62 is formed in the fixed base plate 61 on the upper part of the twisting guide ring 50 and a tension adjusting roller which is inserted into the guide hole 62 and is selectively moved and fixed.
The twisting state of the plied yarn 301 is fixed, and the twisting state of the plied yarn 301 is fixed by the plied yarn tension adjusting device 60 composed of 63, the water tank 71, the coating roller 72 and the coating amount adjusting roller 73 whose position can be adjusted. A heating device 80 for setting and a jumbo winding structure 90 including a feed roller 91, a traverse guide 92 and a cylinder drive drum 93 are sequentially installed to form a ply twisting system 100 as a single machine device. In the other figures, 200 is a spindle belt adjusting means, and 201 is a winding cylinder.

The operation of the ply-twisting system of the embodiment of the present invention thus constructed will be described in detail as follows.
One bobbin thread 300 mounted on each spindle 20 of the twisting table 10 is connected through each process as shown by the chain line in FIG.
After connecting to 201, when power is applied to the device of the present invention to start the operation of the motor 400 and various driving devices, the twisting table 10 is moved by the table driving belt 500 connected to the first pulley 401 of the motor 400. The spindle drive pulley 501 is rotated by the spindle drive belt 501 that is connected to the second pulley of the motor 400.
Is to be rotated separately from the twisting table 10. Therefore, each spindle 20 connected to the spindle drive pulley 30 by the spindle belt 502 is rotated by the twisting table 20.
The rotation of the spindle 20 and the rotation of the spindle 20 are performed around 30 as a center.

Therefore, each yarn 300 unwound by the winding operation of the winding cylinder 201 is twisted by itself by rotation, and after reaching the ply twist guide ring 50 through the yarn tension adjusting device 40, The respective self-twisted original yarns 300 are secondarily twisted in a entangled state as in the prior art to form a plied yarn 301 having a structure as shown in FIG. 6 (B).

The plied yarn of the above structure produced according to the present invention
Since 301 is double-twisted and the twisted state becomes very stiff, it is possible to completely prevent the snarling phenomenon and improve weaving efficiency. It has the characteristics of not only the tactile feel at the time of weaving and the durability of the fabric, but also the light absorption, and the most important characteristic effect is the twisting function by rotation and the difference in physical properties due to the yarn tension adjusting device 40. That is, it is possible to completely twist the raw yarn.

FIG. 6 is a diagram of the ply-twisted state of the ply-twisted yarn.
(A) shows what was twisted by the conventional twisting machine, and FIG. 6 (B) shows what was twisted by the twisting machine of this invention. For example, two yarns having a difference in draw ratio or smoothness of the surface are shown in FIG.
When twisted as shown in (A), the yarn having a relatively large draw ratio is reduced in diameter and length by stretching and twisting, and the contact area between the yarns and the frictional force are extremely small. Steady-state twisting is impossible because the degree of cohesion decreases. In the present invention, as shown in FIG. 6 (B), since each yarn 300 is already stretched and twisted before being twisted, structural deformation hardly occurs at the time of twisting, and the twisting is caused by itself. Since the surface unevenness imparts an excellent degree of binding to each other, it is possible to ply yarns having different physical properties without difficulty.

At this time, by adjusting the tension adjusting roller 45 of the original yarn tension adjusting device 40 to adjust the transfer tension of the original yarn, the number of twists of each original yarn can be arbitrarily adjusted, and the twisting is performed. It is appropriately adjusted in consideration of the physical properties or unique characteristics of each yarn. In the embodiment of the present invention, the number of spindles 20 is six, but
It is needless to say that the number can be increased or decreased to an appropriate number depending on various necessary conditions such as weaving conditions and characteristics of the woven fabric, and in the present embodiment as well, the number of raw yarns to be twisted and twisted depending on the number of connections of the spindle belt 502 can be easily and arbitrarily set. It can be adjusted.

On the other hand, if the spindle belts 502 are connected by crossing in an X-shape, the rotation direction of the spindle drive pulley 30 and the rotation direction of the spindle 20 are made opposite to each other,
Since the twisting direction of each of the original yarns can be opposite to that of the other original yarns or the twisting direction at the time of plying, there is an effect that new ply-twisted yarns having various functions can be processed depending on the yarn type. On the other hand, a single twisted yarn that is twisted through the twisting guide ring 50
301 is transferred to a sizing agent supply device 70 via a sizing / twisting yarn tension adjusting device 60 that adjusts the tension of the doubling yarn 301 by the movement of the tension adjusting roller 63, and is coated with the sizing agent while contacting the coating roller 72. At this time, if the position of the coating amount adjusting roller 73 is adjusted to adjust the pressing degree of the plied twisted yarn 301, the amount of the sizing agent coated on the plied twisted yarn 301 can be appropriately adjusted.

[0026] A ply-twisted yarn 301 that has been coated with a sizing agent
Is fixed in a twisted or twisted state while passing through the heating device 80, and the twisted and twisted yarn 301 passing through the heating device 80 is wound around the winding cylinder 201 via the traverse guide 92 and the cylinder driving drum. It is a thing.

[0027]

As described above, the plied twisted yarn, which has undergone the ply twisting, is not immediately wound up because it undergoes the post-process by another other device, but all the post-processes are performed by one machine. In order to be completed in series, by combining the front and rear process devices into a single device and concentrating them into a single device, the innovative simplification and reduction of the structure and scale of the ply-twist system makes The production cost is greatly reduced,
Since it is possible to install a device that can perform the entire preparation process in the conventional quarter space, there is an effect that the burden of selecting an installation site and cost is reduced, and the management operation is performed efficiently due to the simplicity of the structure. As a result, human labor and time are greatly saved, productivity is improved, and all work processes are performed by one machine, so the frequency of industrial accidents that occur during work is greatly reduced. Will decrease. Further, since each process is continuously performed continuously, there is almost no loss rate of the raw yarn, the preparation process for the next process unlike the conventional one is not required, and the manual work process is reduced to the maximum, the work efficiency is improved. It is an invention that has great effects such as improvement of the above.
