Embodiment Construction

[0023] Below, refer to Figure 1 to Figure 5 One embodiment of the sewing machine according to the present invention will be described. Here, in this embodiment, a sewing machine will be described in which the side operated by the operator of the sewing machine is defined as the front side, and the opposite side is defined as the rear side as a kettle mechanism for interlacing the lower thread and the upper thread. A semi-rotary tank that rotates the middle tank in a reciprocating direction at a predetermined angle (reciprocating half-rotation) is used.

[0024] Such as figure 1 and figure 2 As shown, the semi-rotary kettle 2 of the sewing machine related to this embodiment has: a middle kettle 3, which holds the same unillustrated bobbin housing as the prior art; The middle kettle 3 is held rotatably.

[0025] The driver 5 and the large kettle 6 that make the middle kettle 3 reciprocatingly rotate are fixedly installed under the needle plate not shown in the figure at t...

Abstract

The invention provides a caracol kettle apparatus of sewing machine capable of reliably prevent generating wire jumper or yarn break or fluff of an upper wire loop by preventing separation of sewing needle and point. The caracol kettle apparatus has: a sewing needle (12) forming the upper wire loop (13a) with sewing string (13); a middle kettle (3) for capturing point 3c of the upper wire loop (13a) through rotating action; and a driver (5) of activating the middle kettle to rotate to-and-fro, the driver (5) has a rear-side support section (5e) of the needle, which supports a back surface of the sewing needle (12) opposite to the point (3c); and a front-side support section (5f) of the needle, which supports a front surface of the sewing needle (12).

Description

technical field [0001] The invention relates to a semi-rotary kettle device of a sewing machine, which has a drive for reciprocating rotation of the middle kettle. Background technique [0002] At present, there is known a sewing machine with a semi-rotary kettle, which utilizes the tip of the rotating middle kettle to catch the upper thread loop of the suture thread formed by the sewing needle and make it interlaced with the lower thread to sew. [0003] For example, the existing semi-rotary kettle disclosed in Patent Document 1, such as Image 6 As shown, the middle kettle 17 is rotatably held with respect to the substantially bowl-shaped large kettle 19 fixed on the sewing machine frame. The driver 18 coupled to the rotating lower shaft 20 performs a half-rotational swing. And it becomes the following structure: the driver 18 performs a semi-rotational swing, and the two free ends 18A, 18B of the driver 18 push the middle kettle 17, and make the middle kettle 17 perform ...
