Description

[Detailed Description of the Invention] The present invention relates to a design twisting machine in which the untwisting structure is particularly improved to save labor and energy, and to obtain a stable untwisting effect.

As is well known, in a design twisting machine, two or more kinds of floating yarns such as commercially available spun yarns and core yarns with various shapes and patterns are twisted together, and a presser yarn is then wrapped around the outer surface of this combined twisted yarn. Therefore, various kinds of loop yarns, curl yarns, and other designed yarns are manufactured. However, in these design yarns, S twist and Z
It is customary to finally untwist a designed yarn that has been twisted to a certain extent, and it is well known that a known untwisting V-wire is used for this untwisting. It is a place. This untwisting is a method used to increase the bulk of the yarn, stabilize the twist, and facilitate the raising of decorative yarns.
Conventionally, the untwisting position was placed at the lower end of the hollow spindle for winding the presser yarn.
The untwisting is performed by attaching a wire and passing the combined and twisted design yarn wrapped around the presser yarn through the wire. It is necessary to apply a large number of rotations to the Since the number of spindles per such yarn twisting machine is usually 100 or more, the drive motor thereof also needs to have a large horsepower, and the energy consumption becomes extremely large. Furthermore, the fact that the untwisting V wires are exposed inside the yarn twisting machine means that floating foreign matter may adhere to the yarn.
In addition to causing curling, there are also problems such as lack of stability in the outer shape of the designed yarn after untwisting.

The present invention solves these problems by selecting the untwisting position near the plying part and inside the hollow spindle when untwisting the designed yarn.
It is possible to save labor and energy without requiring a high rotation speed, and it also ensures the stability of the untwisted shape. In a design yarn twisting machine that obtains various decorative yarns by combining and twisting presser yarns, a hollow spindle equipped with a center hole through which the combined and twisted yarns pass is rotatably disposed below the combination and twist of floating yarns and core yarns, The presser yarn bobbin is held on the spindle, and an untwisting V-wire that can be operated from a window hole provided in the spindle is swingably mounted in the spindle directly below the upper entrance for winding introduction of the presser yarn in the center hole of the spindle. , the twisted design yarn around which the presser yarn is wound is led out to the take-up spindle side below the hollow spindle via the V wire and through the center hole.

The present invention will be described in detail below with reference to the illustrated embodiment. In FIG. 1, 1 is a floating yarn, 2 is a core yarn,
As is well known, a spindle 5 is provided on a twisting machine frame 3 so as to be rotatable at variable speeds via a drive belt 4 which can freely rotate in forward and reverse directions via an appropriate drive source and speed change mechanism. A cheese 6 of a floating yarn 1 made of commercially available spun yarn or the like is mounted on a shaft, and the floating yarn 1 is passed through guide knit rollers 7, 7 to a known twisting device 8.
The core yarn 2 is also supplied to the twisting device 8 via a guide bar 10, a snail wire 11, and guide knit rollers 12, 12 from a bobbin 9 mounted on the upper part of the frame 3, for example. A combined twisted yarn 13 is formed by S twist or Z twist. A hollow spindle 15 is rotatably installed directly below the twisting section and rotates via a drive belt 14 that can freely circulate in forward and reverse directions. is held rotatably together with the hollow spindle 15, and furthermore, a take-up spindle 19 is provided directly below the hollow spindle 15 via a drive belt 18 that can freely rotate in forward and reverse circulation, and a take-up bobbin 20 is held on this. be. The hollow spindle 15 is provided with a center hole 15a, and the twisted yarn 13 passes through the spindle 15 through the center hole 15a, and the presser yarn 16 is wound and supplied around the twisted yarn 13 at the upper end of the center hole 15a. , Presser thread 1 is placed on the outer surface of the twisted thread 13.
6 is wound in the same twist direction to obtain the design thread 21, and the design thread 21 is finally sequentially wound onto the winding bobbin 20.

In the present invention, when untwisting the designed yarn 21 as described above, as illustrated in FIGS. 2 and 3, the upper end of the center hole 15a of the hollow spindle 15, that is, the The presser thread 16 is pulled out from the held bobbin 17.
Directly below the upper entrance 22 for winding and introducing the twisted yarn 13, an untwisting V is provided in the center hole 15a.
The wire 23 is mounted in a pivotable interior so as to be swingable.
When installing the V wire 23, attach the cap 2 to the upper end of the opening of the hollow spindle 15 as shown in the figure.
4 is attached by, for example, screw fitting, the above-mentioned upper entrance 22 is opened at the center of the upper end of the cap 24, and insertion holes 25, 25 are provided on the inner peripheral surface surrounding the center hole 15a of the spindle 15. Insertion holes 25, 25
Both leg ends 23a, 23a of the V-wire 23 are pivotally supported by the V-wire 23, and the insertion holes 25, 25 may have a groove shape. Further, the spindle 15 has window holes 15b and 15 at the front and rear positions corresponding to the V wire 23.
b is opened, and by inserting a finger through this window hole 15b and swinging the V wire 23 toward the front side, it is convenient to pass through the first winding. (See Figure 2). Further, in this example, the upper part of the spindle 15 including the cap 24V wire 23 is formed integrally with the spindle 15, but as shown by the dashed line in the figure, the spindle 15 is fixed at 15' and the upper part of the spindle 15 including the cap 24V wire 23 is formed integrally with the spindle 15. The same effect can be obtained even if the upper part is manufactured separately and attached to the spindle 15'.

According to the present invention, the twisted yarn 13 that has been twisted by the twisting device 8 enters the center hole 15a of the hollow spindle 15 from the upper entrance 22, and the presser is wrapped around the twisted yarn 13 at the upper entrance 22. The yarn 16 is introduced into the outer surface of the twisted yarn 13 while being wound in the same twisting direction, and becomes a decorative yarn 21 with a floating yarn 1 core yarn 2 and presser yarn 16. V wire for twisting 2
3, as shown in the third figure, the S-twist is untwisted in the Z-twist direction, and the Z-twist is untwisted in the S-twist direction, and passes through the center hole 15a to the winding bobbin. It is wound up on the 20 side. Conventionally, this untwisting position is the X position in FIG. 1, and as shown in an enlarged view in FIG.
A synthetic resin cylinder 30 with both legs of a V wire 31 embedded integrally is installed at the lower end of the body, and the distance from the twisted part to the X position is L as shown in the figure. Therefore, in untwisting, it is necessary to set the rotation speed of the spindle 15 to an extremely high rotation speed of 7000 rpm. When a high rotational speed per spindle is required, typically more than 100 types of yarn twisting machines are used, so a large horsepower and power consumption of the drive motor is required, and it is also costly. It is disadvantageous. In addition, in the case of the X position as shown in the figure, the untwisting V-wire 31 is completely exposed, and if there is no cover, there is a risk of foreign matter adhering to the design thread 21, and the untwisting There is no limit to the looseness caused by this, and there is a risk that the outer shape of the thread may become uneven.

On the other hand, as in the present invention, the hollow spindle 15
By placing the untwisting position above the center hole 15a of the , the distance of L becomes significantly shortened to l, so if l is reduced to 1/7 of the conventional number, the number of revolutions becomes 1000. Since it only requires rotation, it is extremely advantageous in terms of labor and energy savings, and production costs can also be reduced. Also, connect the V wire 23 to the spindle 1.
By placing the wire 23 inside the V-wire 5, there is no fear of foreign matter adhering to or getting caught, and the swinging of the wire 23 within the center hole 15a can be conveniently done via the initial winding around the V-wire 23.
