Description

The present invention relates to a yarn splicing device for splicing two yarn ends, and in particular, splicing with two yarn ends to be spliced aligned in the same direction. The splicer type splicing device configured as described above and the handy splicer configured to be portable.

As is well known, a conventional yarn splicing device has a yarn splicing device called a knotter that forms a knot (knot) and performs yarn splicing, and two yarn end portions are untwisted in advance, and the yarn end portion is a yarn. In the joint hole, they are overlapped in opposite directions, and the two thread ends are swirled and vibrated by causing the compressed fluid (compressed air, etc.) to act as a swirling airflow on the overlapped portion. A yarn splicing device called a splicer that performs yarn splicing is known.

In the yarn splicing device as described above, in the yarn splicing method using a splicing device called a knotter, the knot portion protrudes over the entire circumference in the radial direction of the yarn as compared with other portions. In the process, the yarn was caught by the knitting needle when passing through the knitting needle, causing thread breakage. On the other hand, in the yarn splicing method using a splicer called splicer, the amount of protrusion of the seam is smaller than that of the knot described above, but there is still a problem of yarn breakage due to being caught by the knitting needle.

In order to solve these problems, a spun yarn splicing method and a splicing device as described in Patent Document 1 have been proposed by the same applicant. However, even in the case of the yarn splicing method and the splicing device described in Patent Document 1, the splicing device for reliably forming a seam portion that should be regarded as the most important in this type of splicing in a uniform state. Was not reached.

Claims (3)

In a yarn splicing device for splicing two yarns to be spliced in a state where the yarn ends are aligned in the same direction, unwinding and twisting of the yarn ends of each yarn are continuously performed by a single air jet nozzle. The air ejection nozzle includes a yarn accommodation hole that accommodates a yarn end portion of two yarns to be spliced, and an air ejection means that ejects an airflow from a direction intersecting the yarn accommodation hole. A clamping means for gripping two yarns accommodated in the yarn accommodation hole on one side of the yarn accommodation hole in the air ejection nozzle, and closing one side of the yarn accommodation hole and piecing A yarn splicing length adjusting means for adjusting the length, and a cutter means for cutting the yarn end side of two yarns on the other side of the yarn accommodating hole in the air ejection nozzle, The airflow is blown to the yarn ends of the two yarns in the yarn receiving hole. And, to the yarn splicing by intertwining, in deriving the tangled portion from the air ejection nozzle, the yarn splicing device being characterized in that the drawn out while pressing in the yarn splicing length adjusting means. The air ejecting means, the clamping means, the yarn splicing length adjusting means, and the cutter means each include an operation cam attached to one cam rotation shaft, and the yarn splicing operation is completed by one rotation of the cam rotation shaft. The splicing device according to claim 1, wherein A base-type splicer that is a handy splicer that splics two spliced yarns with their ends aligned in the same direction, and is pivotally connected around a pivot connection point. A yarn splicing portion including an air ejection nozzle on the movable end side of the base member and the movable base member, and untwisting and twisting the yarn ends of each yarn by a single clamping operation. Yarn that stores the two yarns in a state in which the yarn ejection ends of the two yarns to be spliced are aligned in the same direction. An air ejection means for ejecting an airflow from a direction intersecting the yarn accommodation hole, and being accommodated in the yarn accommodation hole on one side of the yarn accommodation hole in the air ejection nozzle. While holding two yarns, the yarn receiving hole Cutter means that closes one side and adjusts the piecing length and adjusts the piecing length, and cuts the yarn end side of two yarns on the other side of the yarn accommodating hole in the air ejection nozzle A handy-type splicer characterized by comprising:
