[Industrial Application Field] The present invention relates to a yarn splicing device that splices spun yarn by the action of compressed fluid. [Prior Art] A yarn splicing device that splices two yarn ends by applying compressed fluid to the overlapping yarn ends is already known from Japanese Patent Publication No. 55611/1983. There is. This yarn splicing device inserts two yarn ends into a yarn splicing nozzle so that the yarn ends face in opposite directions.
By spouting compressed air into the splicing nozzle, the overlapping portion of the two yarn ends is subjected to effects such as vibration, entanglement, and twisting, thereby splicing the yarn ends. be. [Problems to be Solved by the Invention] The above-mentioned yarn splicing device is suitable for ordinary cotton yarns and long fiber yarns; However, it is possible to create a seam that is insufficient in terms of appearance and yarn strength, especially at both ends of the seam, where the tip of the yarn end is not wrapped around and a long corner-shaped portion separates from the parent yarn is created. It had been. Such woolen yarns are often used for knitwear, and the corner portions get caught in the thread holes of knitting needles, causing yarn breakage. It is an object of the present invention to provide a yarn splicing device particularly suitable for the above-mentioned woolen yarns or other thick yarns. [Means for Solving the Problems] According to the present invention, auxiliary nozzles are arranged on both sides of the yarn splicing nozzle to apply compressed fluid to both end portions of the seam. [Examples] Examples of the present invention will be described below with reference to the drawings. 1 and 2, the yarn splicing device 1 basically includes a yarn splicing nozzle 2, auxiliary nozzles 3 and 4 arranged on both sides of the yarn splicing nozzle 2, and furthermore, untwisting nozzles 5, 6 arranged on both sides;
It is composed of a thread pressing device 7, thread cutting devices 8 and 9, thread shifting lever 10, and thread clamping devices 11 and 12. The yarn splicing device 1 is installed in an automatic winder,
The thread YB on the bobbin side and the thread YP on the package side are sucked and held by the relay pipe 13 and suction mouth 14, respectively, and guided. The yarn splicing nozzle 2 has a yarn splicing hole 15 and a slit 16 into which the yarn end on the bobbin side and the yarn end on the package side are inserted so as to face in opposite directions.
is formed as shown in FIG. 3, and the splicing hole 15 is provided with jetting holes 17 and 18 for jetting out compressed air. In this embodiment, as shown in Fig. 3, the slit 1
Both thread ends positioned at the innermost position relative to 6
Injection holes 17 and 18 are shown drilled at two different positions in the central axis direction of the nozzle hole 15 so that a direct flow acts on YB and YP. Of course, various types of nozzles such as a type that produces a swirling flow, a type that has one injection hole, etc. are applicable. Furthermore, auxiliary nozzles 3 and 4 are installed on both sides of the yarn splicing nozzle 2 with some distance between them. That is, the auxiliary nozzles 3 and 4 are provided at a certain distance S from the yarn splicing hole end faces 2a and 2b of the yarn splicing nozzle 2, and the air flow inside the yarn splicing nozzle 2 and the air inside the auxiliary nozzles 3 and 4 are separated. It is designed so that there is no direct interference with the flow. The above auxiliary nozzles 3 and 4 are yarn splicing nozzles 2
It has almost the same shape and size as the thread joining hole 19,
20, slits 21 and 22 extending throughout the hole for inserting the yarn into the splicing hole, and compressed air injection holes 23 and 24 opening tangentially to the inner peripheral surface of the nozzle are formed. The swirling directions of the airflows ejected from the injection holes 23 and 24 are opposite to each other,
Promotes winding of the tip of the yarn end around the parent yarn. As shown in the first figure, outside the auxiliary nozzles 3 and 4, tubular untwisting nozzles 5 and 6 are arranged which suction and untwist the yarn ends by the action of compressed air. Further outside the untwisting nozzles 5, 6 are guide grooves 25, 26, 27, 28 into which the yarns guided by the relay pipe 13 and suction mouth 14 are individually inserted.
Guide plates 29 and 30 are arranged. Cutters 8 and 9 for cutting each thread YP and YB are arranged inside the guide grooves 25 and 28 into which the end of thread YP on the suction mouth side and the end of thread YB on the relay pipe side are respectively inserted. and each cutter 8,9
The cut yarn ends are sucked into untwisting nozzles 5 and 6. Further, clamp devices 12 and 11 for gripping each thread YB and YP are arranged outside the guide grooves 26 and 27 into which the main thread part of the thread YB on the bobbin side and the main thread part of the thread YP on the package side are respectively inserted. Ru. On the side of the yarn splicing nozzle 2, the yarns YB and YP guided by the relay pipe 13 and the suction mouth 14 are pulled onto the yarn splicing device 1, and each yarn is guided through the guide grooves 25 to 28.
A thread shifting lever 10 is arranged to be inserted at a predetermined position. The yarn splicing operation of the above device will be explained next. In Fig. 8, the yarn YP on both sides of the yarn splicing nozzle 2,
YB is clamped by the thread clamp devices 11 and 12, and the thread shifting lever 10 is operated, and the rod 3 in FIG.
1 is moved in the direction of arrow 32 by a control cam (not shown) and the levers 34, 35 are pivoted clockwise around the support shaft 33, and the thread is cut. In addition, the thread shifting lever 10 and the thread cutting device 8,
9, the thread presser device 7 is on standby at a position 7a shown in two-dot chain line in FIG. Next, as shown in FIG. 9, when the yarn ends YP1, YB1 are sucked by the yarn end untwisting nozzles 5, 6, the yarn shifting lever 10 is activated at the same time or in succession.
moves in the direction 36 away from the yarn, and the yarn end YP1,
YB1 is sucked deep into the untwisting nozzle and untwisted by the air jet as described above to a state suitable for splicing. Note that it is desirable that the suction timing of the untwisting nozzles 5 and 6 is started immediately before the yarn is cut by the cutting devices 8 and 9. That is, when the yarn is cut, tension is applied to the yarn by the suction action of the suction mouth and the relay pipe, so the yarn ends freed by the yarn cutting are scattered, and the ends of the yarn become free from the untwisting nozzle 5. , 6, and the yarn end suction by the untwisting nozzle may not be performed. The supply of compressed air to the untwisting nozzle is performed by switching a valve using a solenoid (not shown). The yarn end YP1,
When YB1 is untwisted to a state suitable for splicing, the yarn pulling lever 10 operates again as shown in Figure 10, guiding the yarn ends YP1 and YB1 to each other and pulling them out from the untwisting nozzles 5 and 6. The untwisted yarn ends are passed through the splicing nozzle 2 and the auxiliary nozzles 3 and 4.
overlap at a predetermined position within. At this time, one lever 35 of the thread shifting lever 10
At the same time, the thread presser plates 38 and 39 of the thread presser device 7 are activated and rotate to the state shown in FIG. A bend is given to the thread between the levers 34. The yarn ends YP1, YB1, which were inserted into the nozzle holes of the untwisting nozzles 5, 6 by the yarn shifting lever 10 and the yarn presser 7, are transferred to the yarn splicing hole 15 of the yarn splicing nozzle 2 and the auxiliary nozzles 3, 4. The threads are drawn into the holes 19 and 20, and are positioned and set in the state shown in FIG. 3 with their yarn ends YP1 and YB1 in contact with each other. Next, after the yarn ends have been set, the yarn splicing is performed by the action of compressed air injected from the compressed air injection holes 17 and 18 of the yarn splicing nozzle 2 shown in FIG. Simultaneously or with a slight delay when twisting is performed with the yarn splicing nozzle 2, compressed air is injected from the fourth and fifth illustrated compressed air injection holes 23 and 24 of the auxiliary nozzles 3 and 4,
Thread splicing is completed. That is, the auxiliary nozzle 3 and the auxiliary nozzle 4 spray compressed air at the same time, and the nozzles 3 and 4 spray the compressed air about 0 to 0.1 seconds later than the splicing nozzle 2. In addition,
This delay time setting can be made arbitrarily. Therefore, first, due to the fluid action of the yarn splicing nozzle 2,
A portion of the yarn ends are mixed, combined, and twisted to form a seam, and the yarn ends can also be sufficiently wrapped around the parent yarn to form a clean seam without any corners. Note that it is preferable that the auxiliary nozzles 3 and 4 spray the compressed air in opposite directions. The jetting direction can be determined in relation to the twisting direction of the yarn, but it is not limited to what is shown in the drawings and can be set arbitrarily. The seam thus obtained is shown in FIG. In addition, Fig. 6 shows a joint J1 of woolen yarn produced by a conventional device, and the long protruding corner portions X1 and X2 on both sides of the joint are different from each other. The appearance has also been greatly improved. Furthermore, the actual measured values for seam strength are shown below.
