Description

[Detailed Description of the Invention] Industrial Application Field This invention involves preparing a wide variety of knitting yarns with different colors, materials, and compositions, and manually selecting a plurality of these yarns to be used in combination. The present invention relates to a knitting needle instruction device for knitting a pattern in a manual or semi-automatic flat knitting machine in which a pattern is knitted while being supplied to knitting needles and a green area of IC stockinette is knitted.

BACKGROUND ART Conventionally, in order to knit a knitted fabric expressing a complicated pattern by using a variety of knitting yarns of different colors and other appearances, a great deal of effort and long hours of concentration are required of the knitting worker.

That is, in order to knit such a patterned fabric, 1
For each course, the work of counting the knitting needles in the knitting needle row corresponding to the section of the pattern, and the work of selecting and accurately introducing a desired knitting yarn into the plurality of knitting needles thus counted according to the pattern are repeatedly performed. Moreover, these operations are carried out by the knitting operator using a secondary drawing drawn on graph paper or the like, while reading the number of knitting needles and the type of knitting yarn.

Since the above-mentioned work is detailed work, the worker's eyes are highly fatigued, and the worker is under a high degree of stress from the beginning to the end of the organizing work, which causes a high degree of mental fatigue. This places a heavy burden on the operator and may even lead to mistakes in organization.

The method of reading only the part necessary for knitting from the 1c pattern shown in the second drafting as that part is easy to misunderstand, counting the number of knitting needles and the type of knitting thread, and remembering it by comparing it to a song. There was also a method in which the organization was performed while singing the counting song. However, in order to knit a single patterned fabric, the counting song is quite long, and the memorability of each knitting worker differs, making it difficult.

On the other hand, conventionally, automatic flat knitting machines have been known that knit patterned fabrics by automatically supplying several types of binding yarns by alternating the thread paths. However, such automatic flat knitting machines are very expensive, and the number of knitting yarns that can be used for knitting at one time is limited to eight types.

Since knitted fabrics with high-quality patterns often use more than eight types of knitting yarn, such knitted fabrics must be knitted manually.

Purpose of the Invention The present invention can lighten the burden on the compiling worker, and thereby prevent compiling mistakes.
It is possible to improve the yield of products, improve work efficiency, significantly reduce production costs, and in itself can be manufactured at low cost. An object of the present invention is to provide a knitting needle indicating device for knitting.
