本発明は工業用ミシンにおける上糸の給糸機
構、詳しくは給糸がくずれ、もつれることがなく
スムーズに給糸され糸切れの虞れが少ない上糸の
給糸機構に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an upper thread feeding mechanism for an industrial sewing machine, and more particularly, to an upper thread feeding mechanism in which the thread is fed smoothly without being twisted or tangled, and there is less risk of thread breakage. It is related to.

た。 A conventional general yarn feeding mechanism feeds yarn to a thread take-up from a bobbin placed on the sewing machine body (for example, an arm) or above the sewing machine body, and the bobbin a' is placed on a table 10 as shown in FIG. It was attached to a post 11 that was fixed upright and fed by pulling up the thread wound around the bobbin a'. For this reason, this conventional product had a problem in that the yarn that had broken off from the bobbin a' became tangled or entangled between the table 10 and the lower end of the bobbin a', causing the yarn to break. Also, if you make sure that the thread does not fall from bobbin a' onto table 10, table 10 and bobbin
There is no risk of the thread getting tangled between A′ and A, but
Thread breakage occurs due to the resistance of the thread. Furthermore, if bobbin a' was attached to table 10 so that there would be no gap between table 10 and bobbin a', there was a risk that the thread would break due to the rotational resistance of bobbin a'. .
そこで、本発明者は種々の実験を重ね鋭意研究
に努めた結果、本発明に至つた。 Therefore, the inventor of the present invention has conducted various experiments and conducted intensive research, and as a result, has arrived at the present invention.
即ち、本発明はボビンをハンガーから懸垂し

ムーズに天秤に供給できるように誘導管をボビン
と天秤との間に配設したものである。 That is, in the present invention, the bobbin is suspended from the hanger so that the thread can be drawn out from the bobbin without resistance, and the guide tube is attached to the bobbin so that the thread can be smoothly supplied to the thread take-up without being subjected to resistance such as wind. It is placed between the balance and the balance.
以下、図面にもとづいて本発明の実施例を説明

ａの外側に嵌装することが望ましい。 In the figure, a indicates a bobbin (woodwind) on which the thread 1 is wound by a method that is easy to unravel, such as by combination building, and the upper end of this bobbin a is attached to the guide groove b1 of the hanger b. The thread 1 is a thread made of nylon, polyester, etc., and is attached to the bobbin a.
Although not shown, if it naturally unravels and falls under its own weight when suspended, a cylindrical elastic body (for example, nylon circularly knitted) can be fitted to the outside of bobbin a. is desirable.
このボビンａは従来と同一のものであり、正逆
反対にハンガーｂに固定されている。ａ１はボビ
ンａの座盤を示す。 This bobbin a is the same as the conventional one, and is fixed to the hanger b in the opposite direction. a1 indicates the seat of bobbin a.

る。 In this way, the needle thread 1 of the bobbin a hangs down on the catch tray b 2 below the bobbin a by its own weight and is placed thereon for approximately one turn, and is introduced into the guide tube b through the through hole of the catch tray b 2 . Ru. Then, when the upper thread 1 is passed through the guide tube d and passed through the needle body 3 via the thread take-up lever 2 of the sewing machine main body A and operated, the thread 1 is moved to the receiving tray b 2 as shown in the figure.
The yarn is unwound upwards and then fed into the needle body 3. FIG. 4 shows an upper thread feeding mechanism in a multi-needle sewing machine.

ツトするのであるから、その構造が極めて簡単で
あり、セツトの作業性も損なわれない。 According to the present invention, since the bobbin of the needle thread is suspended from the hanger, the needle thread is let out downward from the bobbin without resistance and is supplied to the needle body of the sewing machine main body. Therefore, compared to the conventional product, the upper thread is fed smoothly without any snags, and cutting of the upper thread can be completely prevented. Moreover, since the conventional bobbin is set on the hanger in reverse, the structure is extremely simple and the workability of setting is not impaired.
更に、本発明によれば、ボビン下方に固定した

り、上糸切れを防止できる。 Further, according to the present invention, since the guide tube is disposed between the tray fixed below the bobbin and the thread take-up, the upper thread is fed through the guide tube. Therefore, wind pressure caused by the vibration of the sewing machine, the feeding of the product to be sewn by the automatic sewing machine, etc.
The needle thread fed to the thread take-up is not affected. Therefore, the upper thread is smoothly supplied from the bobbin to the take-up thread without being subjected to resistance such as wind pressure, and it is possible to prevent the upper thread from getting tangled or breaking.
依つて所期の目的を達成する。 In this way, the intended purpose is achieved.
