Abstract

본 발명은 재봉기의 속도제어장치에 관한 것으로, 작업대상에 장착된 재봉기와, 이 재봉기를 구동시키는 구동모터와, 상기 구동모터의 회전속도를 제어하는 속도제어수단과, 상기 속도제어수단과 연동설치된 페달을 갖춘 공업용 재봉기에 있어서, 상기 페달(4)의 조작에 따라 회동되는 아암과(13)과, 상기 아암(13)의 작동에 따라 회전되며 선단에 캠(11a)을 갖는 캠축(11)과, 상기 캠(11a)의 회동궤적에 따라 슬라이드작동 가능케 되며 일측에는 홀소자(22)에 대향하도록 자석(20)이 설치된 슬라이드판(17)으로 이루어져 구조가 간단하고 소형화간 가능하며, 직선적으로 작동되는 슬라이드판에 의해 기능 및 속도제어가 용이하게 되어진다.The present invention relates to a speed control apparatus for a sewing machine, comprising a sewing machine mounted on a work object, a driving motor for driving the sewing machine, speed control means for controlling a rotational speed of the driving motor, and interlocking with the speed control means. In the industrial sewing machine equipped with a pedal, an arm (13) rotated by the operation of the pedal (4), a cam shaft (11) rotated by the operation of the arm (13) and having a cam (11a) at the front end; In addition, the slide can be operated according to the rotational trajectory of the cam 11a, and on one side, the slide plate 17 is provided with a magnet 20 to face the hall element 22. The slide plate is made to facilitate the function and speed control.
