Problems solved by technology

[0006] However, in the case of the above-mentioned Patent Document 1, although the height of the bottom dead center of the vertical motion of the intermediate presser foot can be adjusted, the amplitude of the vertical motion cannot be changed.
Therefore, there are inconveniences in that the thickness of the material such as cloth to be sewn cannot be adequately handled, and in addition, the shrinkable material cannot be adequately handled.

Embodiment Construction

[0049] (The overall structure of the electronic cycle sewing machine)

[0050] based on Figure 1 to Figure 22Embodiments of the present invention will be described.

[0051] In this embodiment, an electronic cycle sewing machine will be described as an example of the sewing machine. An electronic cycle sewing machine is a sewing machine that has a holding frame that is used as a cloth holding portion for holding the cloth of the sewn object to be sewn. The stitches of the specified sewing data (stitch pattern).

[0052] Here, the direction in which the machine needle 108 described later moves up and down is defined as the Z-axis direction (up-and-down direction), and one direction perpendicular thereto is defined as the X-axis direction (left-right direction). The direction perpendicular to the two directions of defines the Y-axis direction (front-rear direction).

[0053] Electronic cycle sewing machine 100 (hereinafter referred to as sewing machine 100), such as figure...

Abstract

The sewing machine capable of optimizing the vertical action frequency of the middle pressing foot includes one vertical actuating mechanism for the needle to move up and down, one locating mechanism for locating the sewn fabric and the needle, one middle cloth holding mechanism to make the middle pressing foot move up and down while maintaining the sewn fabric without being lifted together with the needle, and one middle pressing foot height regulating mechanism provided with driving source for regulating the height of the middle pressing foot and fitted with one action controlling mechanism for regulating the vertical amplitude of the middle pressing foot.

Description

technical field [0001] The invention relates to a sewing machine capable of controlling the up and down movement of a middle cloth pressing mechanism. Background technique [0002] In the conventional sewing machine, the needle is transported and sewn at any position while the cloth is held by the frame-shaped pressure plate and conveyed along the XY direction. Middle cloth pressing mechanism that presses down the periphery of the needle penetration part of the cloth when it is raised. [0003] In this middle cloth pressing mechanism, when the machine needle rises from the cloth, the middle presser foot is pressed downward by the elastic force to press the cloth downward. rise together. [0004] As such an intermediate presser mechanism, known is a mechanism that displaces the swing fulcrum of a swinging body that moves the intermediate presser up and down and adjusts the height of the intermediate presser from the needle plate (for example, refer to Patent Document 1 ). ...
