Description

DETAILED DESCRIPTION OF THE INVENTION (Objective of the Invention) The present invention provides a high-quality, uniformly spaced loop or beard that is formed without slipping and without being adversely affected by the air flow caused by ventilation in a factory. This invention relates to a yarn twisting mechanism in a yarn twisting machine or winder, which aims to improve the work environment by allowing decorative twisted yarn with high commercial value to be obtained and at the same time, by allowing sufficient ventilation in a factory during yarn twisting work.

(Prior Art) Conventionally, a twisting mechanism in a twisting machine or winder that produces decorative twisted yarn with loops or whiskers formed on the surface of the yarn twists a first yarn a wound around a thread hook A as shown in FIG. By inserting the thread into the thread path C and letting out the first thread a more than the second thread b that is delivered from the thread hook B, the second thread is made to have a loop or whisker shape. The third thread f wound around the bobbin F attached to the spindle E is passed through the twisting tube D and then into the hollow spindle E.
Wrap it around thread a and second thread b to form a loop or whisker P.
It was intended to be fixed so that it would not shift.
In this twisting mechanism, immediately after the first yarn a is intertwined with the second yarn b so as to form a loop or whisker, it is rubbed by the head of the twisting tube D, so that the position of the loop or whisker P is shifted. This often results in decorative twisted yarns in which the intervals between the loops or whiskers P are irregular.

In addition, in this yarn twisting mechanism, the yarn twisting tube D and the spindle E
During this time, the exposed threads would be affected by the airflow caused by the ventilation in the factory and would become partially slack, resulting in uneven tension in the threads. Thread path D
The intervals between the loops or whiskers P formed at the exit of the thread tend to shift and become irregular, and even if a third thread is wound around the twisted thread in this state, only a decorative twisted thread with poor appearance and low commercial value is obtained. Ta. As a result, the factory cannot be sufficiently ventilated, and factory windows are not allowed to be opened even during hot summer work, forcing workers to work in an environment that is extremely poor in terms of factory hygiene, resulting in poor work efficiency. This caused various inconveniences.

(Structure of the Invention) In order to solve the above-mentioned disadvantages, the present invention involves twisting a first thread around a second thread so as to form a loop or whiskers, and then immediately wrapping a third thread around the thread to form a decorative twisted thread. An example will be described below.

In FIG. 1, payout rolls 3 and 4 are rotatably provided below the two thread hooks 1 and 2 and are linked to a drive source, and are in circumscribed contact with the payout roll 3, a presser roll 5, and a payout roll 4. Hold down roll 6
is provided rotatably. The payout roll 3 that pays out the first yarn a has a rotational speed larger than that of the payout roll 4 that pays out the second yarn b, so that the amount of the payout of the first yarn a can be changed to the amount of payout of the second yarn b. More than quantity. The second thread b let out from the thread hook 2 is made to hang down, and is inserted into the insertion hole 9 of a hollow spindle 8 supported by a stay 7 so as to be rotatable in one direction. A hollow yarn path 10 is provided between the pay-out roll 4 and the spindle 8 substantially at right angles to the second yarn b,
The first yarn a fed out by the feeding roll 3 is passed through the yarn path 10 and attached to the second yarn b. The spindle 8 has a bobbin 11 wound with the third thread f.
is attached, and the third thread f is fed out from the bobbin 11.
into the insertion hole 9 from the upper end of the spindle 8, and
Add it to the second thread a and the second thread b. An endless belt 12 is attached to the lower part of the spindle 8, and is adapted to rotate the spindle 8 in the direction of arrow R.
Further, an inner cavity 13 having a larger diameter than the insertion hole 9 is provided at the lower end of the spindle 8 . spindle 8
A twisting tube 14 whose axis is aligned with that of the spindle 8 is supported on the stay 7' so as to be rotatable in the same direction as the rotational direction of the spindle 8 or in the opposite direction (direction of arrow S). The upper end of this twisting tube 14 is placed close to the lower end of the spindle 8 or inserted into the bore 13 as shown in the figure. An insertion hole 1 is provided at the lower end of the twist tube 14.
A pin 16 perpendicular to 5 is passed through the twisting tube 14, and the inside of the twisting tube 14 is divided into two chambers by this pin 16. A driving roll 17 is provided below the twisting tube 14.
A winding roll 18 circumscribing the winding roll 18 is provided to wind up the twisted decorative twisted yarn Y.

In the figure, reference numeral 19 is an endless belt that rotates the twisting tube 14 in the direction of arrow S. The direction of rotation of the twisted yarn tube 14 is not limited to the direction of arrow S, but may be rotated in the direction of arrow S' depending on the type of decorative twisted yarn.

(Function of the Invention) To explain the function of the present invention, the second thread b let out from the thread hook 2 is linearly drawn into the insertion hole 9 of the spindle 8, but the second thread b let out from the thread hook 1 Since the rotation speed of the pay-out roll 3 is higher than the rotation speed of the pay-out roll 4, the amount of the first yarn a is paid out. The second
It becomes entwined with yarn b and becomes a false twisted yarn. In this state, the third thread f of the bobbin 11 is immediately wound to fix the loop or whisker P formed by the first thread a, and the rotation of the twisting tube 14 causes the three threads to be Twisting is given to a, b, and f in the same direction, and the decorative twisted yarn Y is wound up on the winding roll 18. When the three yarns a, b, and f pass through the twisting tube 14, the three yarns a, b, and f are pressed against the inner surface of the twisting tube 14 by the pin 16 of the twisting tube 14.
The rotation and vibration of the twisting tube 14 tends to cause loops or whiskers to form, and by rotating the twisting tube 14 at high speed, the three yarns a, b, and f tend to become entangled.

The spindle 8 and the yarn path 10 and the spindle 8 and the twisting tube 14 are close to each other and are unlikely to receive air resistance.

(Effects of the Invention) The present invention arranges a hollow spindle equipped with a bobbin above, and arranges the twisting tube close to the bottom of the spindle or inserts it into the inner cavity of the lower end of the spindle to connect the first thread with the thread tube. Immediately wind the third yarn around the false twisted yarn formed to exhibit a loop or whisker shape due to the entanglement of the second yarn, and intertwine the three yarns in the same direction with a twisting tube to form a decorative twisted yarn. As a result, the distance between the yarn path and the spindle and the distance between the spindle and the twisting tube can be reduced, the slack in the yarn due to air flow caused by ventilation in the factory can be reduced, and the first yarn, which is a false twisted yarn, can be reduced. And, before the second yarn is rubbed by the twisting tube, a third yarn is wrapped around it to fix the loop or whisker so that the position of the loop or whisker does not shift, so that the loop or whisker will not slip even if it is rubbed by the twisting tube. A decorative twisted yarn of high quality and high commercial value can be obtained, which is formed at equal intervals without any twisting.

In addition, since the factory is not adversely affected by air flow, the factory can be sufficiently ventilated, and the factory windows can be opened to perform yarn twisting work, improving the working environment and reducing the effects on factory hygiene for workers. This greatly improves work efficiency.
