DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pneumatic yarn splicing device, in which the yarn ends are untwisted and spliced in a series of yarn guide grooves, and at the same time the fibers at the yarn ends are untwisted and separated. The purpose is to cut the yarn end to a desired length within the groove without using a cutter, and the yarn end untwisting groove is characterized in that a protrusion is provided in the yarn end untwisting groove to narrow the cross section of the untwisting groove.

In a pneumatic yarn splicing device, the yarn ends to be spliced are untwisted, the fibers at the yarn ends are separated, the yarn ends to be spliced are aligned, and pressurized air is blown onto the part to create a swirling flow. The fibers at each end of the thread are twisted to form an envelope, and the ends of the thread are made into a single piece for splicing. These processes such as untwisting and wrapping are performed in the groove that accommodates the yarn ends, but in order to equalize the length of the untwisted yarn ends, a cutter installed outside the groove is operated. I had to cut the end of the thread.
Therefore, the yarn splicing operation time becomes longer by the time it takes to operate the cutter, which is undesirable in terms of work. Further, by providing the cutter, a cam mechanism and other members are required.

Therefore, in the present invention, in the yarn end untwisting groove, at the same time as untwisting, the yarn fibers are caused to collide with a protrusion provided on the inner wall of the groove by an air flow for untwisting, and the yarn ends are cut at this part. This saves cutting time and cutting equipment.

At this time, the bobbin side yarn end YB is clamped by the swing lever 32 and stopper 33 of the bobbin side clamp device 31 via the hook portion 42 of the swing guide plate 38. In addition, the package cage side thread end YP is
Swivel lever 35 of package side clamping device 34

At this time, the yarn ends YB, YP receive the jet of gas from the gas jet nozzles 13, 14, and in the yarn end untwisting grooves 3, 5, in this embodiment, the jet of air flows in the direction of untwisting the Z twist. The yarn ends are untwisted by the vortex generated by the yarn. The degree of untwisting is determined by the gas jet nozzles 13, 14.
It can be adjusted as appropriate by changing the pressure and ejection time of the gas ejected.

The fibers constituting the yarn end that are being untwisted due to the above-mentioned turning of the yarn end come into contact with the protrusion 18 in the groove, and fiber breakage occurs at this portion. The cut fibers are blown out to the outside by a jet stream from a gas jet nozzle directed toward the opening of the groove. The position at which the yarn end is cut is related to the length of the seam to be spliced, and also to the appearance, texture and binding strength of the spliced seam.

Next, the thread shifting levers 27 and 28 are operated again to pull the thread ends together, and the package side thread end and the bobbin side thread end are positioned so as to overlap, and pressurized gas is sprayed from the gas jet nozzle 12 to the overlapping thread ends. The swirling flow generated there causes the untwisted yarn ends to be entangled and integrated, and then the parts further swirl to generate twist in the integrated part, and The fiber ends are entangled on both sides, and the splicing is completed without creating any corners. During the above-mentioned yarn splicing operation, gas is ejected from the gas ejection nozzles 13 and 14, so an air current toward the opening direction is generated in the yarn end untwisting grooves 3 and 5, and in the yarn twisting section 7. The fibers at the ends of the untwisted yarns that are being twisted together are always pulled along with the airflow going outward from the yarn twisting section 7, so when the fiber ends are connected as a yarn, the fiber ends naturally This prevents the threads from getting entangled with each other and causing protrusions such as corners.

The device of the present invention untwists and wraps the yarn ends of the yarn splicing device in which compressed fluid is applied to the yarn end portions 12 overlapped with each other as described above so that the fibers of the yarn end portions are wrapped around each other. The part is formed into a series of continuous grooves, the yarn ends to be spliced are introduced into the groove, a jet stream directed toward the opening of the groove is applied to the yarn ends, and when the yarn ends are untwisted, Since the fibers constituting the yarn end hit the protrusions in the groove and are cut at that point, the yarn end is cut at the same time as the yarn end is untwisted.
This is effective in shortening the yarn splicing time, and also eliminates the need for a device for yarn cutting.

When trying to wrap the overlapping untwisted yarn ends,
Since the airflow is generated in the direction of the opening of the untwisting groove, a force is constantly applied to the yarn end in the pulling direction, so that the splicing can be performed with the untwisted fibers aligned in the same direction. Therefore, the ends of the fibers do not protrude asymmetrically and produce small knob-like protrusions.

Further, since the splicing process is carried out inside the groove-like body, even if the yarn is rotated by the jet stream, it rotates within a series of grooves, so that the cross section of the yarn will not be made asymmetric.
