Embodiment Construction

[0055] (Overall configuration of the embodiment)

[0056] Below, based on Figure 1 to Figure 13 , the button sewing machine 100 according to the embodiment of the present invention will be described.

[0057] figure 1 is a perspective view showing the main configuration of the button sewing machine 100, figure 2 It is a block diagram showing the main configuration of the button sewing machine 100 .

[0058] The button sewing machine 100 is a machine that sews a button B onto a cloth C using a sewing thread T through the cooperative action of the vertically moving needle 11 , the looper 41 , and the thread resting member 42 .

[0059] Button sewing machine 100, its whole is made up of: the sewing machine base plate 103 that is positioned at its lower part, the sewing machine vertical body portion 101 that is erected upwards from one end portion of the rear of the sewing machine base plate 103, and the sewing machine vertical body portion 101 along the top of the sewing ma...

Abstract

This button sewing machine is equipped with a vertically moving mechanism which drives the sewing needle (11) in the vertical direction while performing a needle swinging, a button holding mechanism (13), a fabric holding member (15) which is extended to the rear side, and folds back and holds the article (C) to be sewn, and a fabric moving mechanism (34) which moves and positions the article to be sewn. The button sewing machine is also equipped with button moving mechanisms (31, 32) which move and position a button (B), a looper (41) which forms a loop by catching a sewing thread, and a thread gathering member (42) which makes the sewing thread between the article to be sewn and the looper avoid the sewing needle which is lowered. A needle swinging limiting means (81) which performs a control for moving the button in the opposite direction from the needle swinging by the button moving mechanism so that the needle swinging may not be performed exceeding a limit amount for the needle swinging. The button sewing machine suppress a thread gathering defect.

Description

technical field [0001] The invention relates to a button sewing machine for positioning buttons and objects to be sewn respectively relative to machine needles. Background technique [0002] Past button sewing machine 200, such as Figure 16 As shown, there are: a needle action mechanism (not shown) that drives the needle 201 in the up and down direction while adjusting the amount of swing in the left and right direction, and a holding mechanism (not shown) that holds the button B below the needle 201 (not shown). As shown in the figure), and the cloth holding mechanism ( not shown), and the cloth moving mechanism (not shown) that moves and positions the cloth C along the front-back direction by the cloth holding member, and moves the cloth C along the swing direction and by the cloth moving mechanism by the button holding mechanism The button moving mechanism (not shown) that moves the button B in the moving direction, the looper 202 that catches the thread T from the lowe...
