Abstract

PURPOSE:To decrease generation of faulty yarn and waste by nipping roving between back rollers in drafting part and sliver bobbin, evacuating to outside of affecting region and simultaneously cutting filament for generation of yarn breakage in spinning of conjugate yarn. CONSTITUTION:Roving 2 is fed to roller drafting part of spinning machine and multifilament 13 of raw silk or synthetic fiber is fed in another route, then the both are joined at front rollers 10 and 11 of drafting part to form conjugate yarn. In said process, roving 2 is nipped at intermediate of back rollers 4 and 5 in drafting part and sliver bobbin A by nipping means 19 and said roving 2 is evacuated to outside of draft-affecting region, then draft action is stopped, for generation of yarn breakage. Multifilament 13 is simultaneously cut by cutting means 15 and feeding of said multifilament is stopped.

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for spinning composite yarns made from spinning fibers and raw silk or synthetic fiber filaments. The present invention relates to a spinning method that can minimize the generation of defective yarn and waste when manufacturing composite yarn using a spinning machine.

(Prior art) In spinning composite yarns made from spinning fibers and raw silk or synthetic fiber filaments, when the composite yarn wound on the spindle breaks, the rovings supplied in large quantities later rotate. Various obstacles were tangled up in various places.

In order to prevent these problems, Newmar was devised, and a measure was taken to suck it in through its nozzle. It is not easy for operators of Kotoroga machines to immediately splice yarn breaks that occur indiscriminately on each of the spindles lined up in a row, as it is difficult to secure manpower in recent years, and this is becoming more and more common in order to reduce costs. Due to the increased speed, a delay in yarn splicing leads to the generation of a large amount of waste, and there is a need for measures to minimize the amount of roving waste sucked into the new man nozzle.

Although the purpose of 0% can be achieved, new problems arise when the spun yarn is a composite yarn as described above. That is? In M-ply yarn spinning, in addition to the cutting of the resulting composite yarn itself, so-called one-sided breakage occurs in which only either the spinning fiber bundle or the synthetic fiber filament is cut, and if this is left untreated. The generation of defective yarns is observed over a long period of time.

The present invention not only detects the cutting of the composite yarn itself by a specially provided sensor, but also stops the supply of all constituent materials even in the so-called one-sided state where either one of the spinning fiber bundle, raw silk, or synthetic fiber filament is cut. The purpose of this invention is to promote a spinning method that reduces the amount of raw material that becomes waste, prevents the production of defective yarn, and reduces costs.

(Means for Solving the Problems) The present invention has the following configuration to achieve the above-mentioned problems. That is, the roving of the spinning fiber is supplied to the roller draft area of the spinning machine, and the raw silk or synthetic fiber multifilament is supplied from a separate route different from this, and both are fed by the fan a-lar in the F' raft area. In a composite spinning method that merges yarns, a yarn breakage signal detected by a sensor causes
The roving between the back roller and the shinomaki of the relevant weight is held by a member provided on the machine base, and the roving engaged with the back roller is moved out of the action area of the tombubano crawler from the position during normal operation. At the same time, the running of the roving is stopped.
The gist of this is to cut and grip filaments on different paths.

When the composite yarn (17) breaks and the sensor (18) issues a thread breakage signal, the solenoid (28) responds to this.
is activated to raise the lifting rod (28') and remove the fixed pawl (27) supported by it from the nip lever (20), which in turn causes the roving guide (25) and nip lever (
20) moves to the right due to the elastic force of spring A (26), and the movable surface (34) and fixed surface (35) are in close contact with each other, causing the roving (2
), simultaneously move the roving (2) (2') to the position where it hangs over the tip guide groove of the roving guide (25), and introduce it into the concave circumferential groove (4') of the back top roller (4). At least let this fit in. The roving (2) is gripped by the moving surface (34) and the fixed surface (35) and stops running at the same time.
It is released from the grip of the pair of back rollers and the delivery to the roller draft area is stopped.

Also, to explain how to prevent the occurrence of defective yarns caused by one side breakage, since one side breakage caused by roving yarn breakage naturally causes the interruption of spinning of the composite yarn, it is necessary to install a thread cut sensor that detects only roving breakage. is not practical, so the thread trimming sensor with one-sided breakage is not suitable for the top yarn guide (1
The object of the present invention can be achieved by providing the braiding thread supply stop mechanism (19) only in the top guide (15) in response to the no thread signal from the top guide (15).

(Effects of the Invention) As in the above-mentioned embodiments, the present invention enables the entire supply of materials to be processed even when the supply of roving yarn, raw silk or synthetic fiber multifilament is out of supply, and spinning of the composite yarn itself is interrupted. This is to completely prevent waste or defective yarns from the composite yarn spun material mentioned at the beginning, and is very effective when the spinning fiber is an expensive material such as silk spun material.

1) Composite yarn in which roving of spinning fiber is supplied to the roller draft area of a spinning machine, and raw silk or synthetic fiber multifilament is supplied from a separate route different from this, and both are merged at the front roller of the draft area. In this spinning method, a yarn breakage signal detected by a sensor causes the roving between the back roller and the shinomaki of the relevant plow to be gripped by a member installed on the machine base, and the roving engaged with the back roller to be gripped during normal operation. A method for spinning a composite yarn, characterized in that the running of the roving is stopped by retracting the roving from a position outside the action area of the top back roller, and at the same time, the filament on a different path is cut and gripped.
