Abstract

The invention provides a button supply device for a sewing machine. The button supply device can uniformly perform depth adjustment of a button storing part. A horizontal feeding mechanism (10) of the button supply device is provided with: a rotary body (20) provided with a plurality of button storing parts (23, 24, 25) opening at the radial external side, at an interval of a certain angle and along the circumferential direction; a drive unit making the rotary body rotate and conveying buttons in the plurality of storing parts; and an outer circumferential cam (50) installed on the rotary body and capable of adjusting the rotation angle with the rotation center of the rotary body as the reference, for the radial inner side, determining the depths of the plurality of button storing parts, and provided with a plurality of cam parts (55) with the same shape and at an interval of the angle the same with that of the plurality of button storing parts.

Description

technical field [0001] The present invention relates to a button supply device which supplies buttons to a sewing machine. Background technique [0002] Currently, as a button supply device that supplies buttons from a button supply source to a button sewing machine, for example, a button supply device disclosed in Patent Document 1 ( Figure 11 ). [0003] Button feeding device 1000 in Figure 11 The button supply source is arranged on the right side, and the button sewing machine is arranged on the left side. [0004] In the button supply device 1000, the button conveyance path is made between a pair of button guides 1001 and 1002, and on this conveyance path, Figure 11 A conveyor belt (not shown) for transferring buttons is arranged on the left side of the button, and an upper guide portion 1003 is provided to cover the conveying path from above and limit the height of the button conveying path. [0005] Also, at the end of the conveying path of the conveyor belt ( Fig...

AI Technical Summary

Problems solved by technology

[0015] At this time, when the adjustment of the position of the adjustment part 2231 is not appropriate, and the button B1 enters too much inside, the button B2 of the next supply order also partially enters the cutout 2241, and when the rotating plate 2240 rotates, the button B2 and the cutout 2241 will be separated. The edge on the side in the direction of rotation is in contact, and it may be bounced off.

[0016] In addition, if the adjustment of the position of the adjustment part 2231 is not appropriate, and the button B1 cannot completely enter the cutout part 2241, when the rotating plate 2240 rotates, it will contact the button delivery port 2101 of the button supply part 2100, and the button B1 will be caught, causing Bad condition that the button B1 is broken or the rotating plate 2240 is stopped
