Coiling button-sewing machine

Abstract

This invention provides a winding button attaching machine, including a thread sender that orderly sends suture by ending a thread sending component hooking the suture to reciprocate surrounding fulcrum shaft. The winding button attaching machine uses a nail catching process and a winding process as a cycle, cuts thread after each process, automatically processes the switch of increasing and reducing the reciprocating range of the thread sending component so as to enable the thread sending amount in the nail catching process to be larger than that in the winding process. Therefore, the predetermined setting operation is simplified so as to easily use the winding button attaching machine, at the same time, thread sending amount in each process is changed to be suitable so that the winding button attaching with beautiful exterior appearance in the finishing state can be reliably realized.

Description

technical field [0001] The present invention relates to a wire-wound button sewing machine that combines a button sewing process of sewing various buttons on cloth such as men's and women's clothing, and buttons sewn to the cloth through the button sewing process with buttons. The thread winding process for reinforcing the button thread by winding the button thread between the materials is performed as a cycle, and the thread trimming is performed after the button sewing process and the thread winding process to cut the needle thread between the needle and the material. Background technique [0002] In this winding button machine, whether it is Image 6 (a), Image 6 (b) shows the fastening process is still in Figure 7 (a), Figure 7 During the thread winding process shown in (b), the suture thread drawn from the thread supply source (not shown), that is, the needle thread T, passes through the thread regulator, thread delivery device and multiple thread guides provided on...

Problems solved by technology

[0006] However, as described in the above-mentioned Japanese Unexamined Patent Application Publication No. 2002-177679, when the microcomputer controls the energization amount to adjust the rotation angle of the motor to change the setting and change of the feeding amount of the thread, before the button sewing operation starts, In addition to setting the number of stitches in each process, it is necessary to perform complicated and cumbersome pre-operations such as inputting numerical values ​​for setting the feeding amount suitable for the buttoning process and the winding process, and there is a high possibility of The input setting of this value is forgotten or a setting error occurs, and there is a problem that it is difficult for operators who lack mechanical knowledge to use
