Abstract

재봉틀의 아암내에서 지지되고 한단에 복수개의 재봉틀 바늘을 설치해서 재봉틀의 상축에 연동해서 상하 운동을 하는 바늘대와 재봉틀의 노루발의 아래편에서 타원형 궤적을 그려 작동하는 하향 전송 톱니와 하향 전송 톱니에 마주하는 상향 전송 톱니를 구비한 평바늘질 재봉틀에 있어서 상향 전송 톱니의 구동 기구를 재봉틀의 머리부분안에 수용해서 윤활유의 비산이나 소음 발생을 적게 함과 동시에 위 무늬실용의 스프레더의 운동의 방해가 되지 아니하고 더욱이 상향 전송 톱니에 전송 효율이 좋은 운동궤적을 부여하는 상향 전송 기구를 얻는다.It is supported within the arm of the sewing machine and installs a plurality of sewing machine needles at one end and faces the downward transmission tooth and the downward transmission tooth which draw an elliptical trajectory under the needle bar of the sewing machine and the needle bar that moves up and down in conjunction with the upper axis of the sewing machine. In the flat needle sewing machine provided with the upward transmission tooth, the drive mechanism of the upward transmission tooth is accommodated in the head of the sewing machine to reduce the lubrication of the oil and the generation of noise, and to prevent the movement of the spreader for the upper thread. Furthermore, an uplink transmission mechanism is provided which gives an uplink transmission tooth a motion trajectory with good transmission efficiency.

상기 평바늘질 재봉틀에 있어서 상기 아임(1) 안에 상기 상축에 연동하는 전후 요동 링크 기구 및 상하 요동 링크 기구를 설치함과 함께 상기 아암내의 턱부분에 수평 방향의 원형구멍에 회전이 가능하게 끼워 맞춘 원주형상 팁으로 형성되는 베어링(13)을 설치하고 그것의 베어링에 상향 전송축(9)을 설치하고 그것의 베어링에 상향 전송축(9)을 상하로 미끄럼 운동이 가능하게 관통시켜서 그것의 상향 전송축의 하부를 아암에서 아래편으로 돌출시키고 그것의 하단에 상향 전송 톱니(10)를 설치하는 한편 그것의 상향 전송축의 상부를 전후 요동 링크 기구 및 상하 요동 링크 기구에 연결하고 상기 베어링의 원주 형상 팁(13)의 회전 중심을 바늘대(3)의 쪽으로 되도록 설치하여 그것의 아래편에서 상향 전송 톱니에 타원운동을 시키도록 하였다. 또 상하 요동 링크 기구의 상향 전송 축과의 연결부분에 압축 스프링(39)을 구비한 신축 로드(36)를 사용하였다.In the flat needle sewing machine, a front and rear swing link mechanism and a vertical swing link mechanism interlocked with the upper shaft are installed in the sub-membrane and rotatably fitted in a horizontal circular hole in the jaw portion of the arm. By installing a bearing 13 formed with a cylindrical tip and installing an upward transmission shaft 9 in its bearing and sliding the upward transmission shaft 9 up and down in its bearing so as to allow the upward movement thereof. Projecting the lower part of the shaft downward from the arm and installing an upward transmission tooth 10 at the bottom thereof, while connecting the upper part of its upward transmission shaft to the forward and backward swing linkage and the up and down swing linkage and the cylindrical tip of the bearing ( 13) was installed so that the rotation center of the needle bar (3) toward the elliptical movement of the upward transmission tooth from below it. In addition, an expansion rod 36 having a compression spring 39 was used as a connection portion with the uplink transmission shaft of the vertical swing link mechanism.

Claims

Downward transmission operating by drawing an elliptical trajectory under the needle bar installed at the bottom of the presser foot and the needle bar which is supported in the arm of the sewing machine's closed structure and installed at the bottom with a plurality of sewing machine needles in conjunction with the upper axis of the sewing machine. In a flat needle sewing machine having an upward transmission tooth facing a tooth and a downward transmission tooth, a front and rear swing link mechanism and an upper and lower swing link mechanism which interlock with an upper shaft are provided in the arm, and at the jaw portion of the arm, Install a bearing consisting of a circumferential tip rotatably fitted in a horizontal circular hole, through which the upward transmission shaft slides upward and downward to protrude the lower portion of its upward transmission shaft downward from the arm; While installing the upward transmission cogs at the bottom of it, its upward transmission shaft The upper part is connected to the forward and backward swing link mechanism and the up and down swing link mechanism so that the rotational center of the cylindrical tip of the bearing is set in the axial direction of the needle bar so that the elliptical motion of the upward transmission tooth is beneath it. Flat needle sewing machine having an upward transmission mechanism.

The upper and lower swing link mechanisms of claim 1, wherein the upper and lower swing link mechanisms are pinned to a link connected to the swing lever, and are supported by the upper and upper portions of the expansion rod and the upward transmission shaft with the compression spring inserted therein, and the lower portion of the expansion rod slides. The upper and lower pins are pushed to the lower end of the elastic rod by the compression spring, and when the pin is lowered by the swing lever, the upward transmission shaft descends through the compression spring of the elastic rod and the upper and lower pins. When the upward transmission shaft is prevented from descending, the compression spring is pushed down the upper and lower pins and the elastic rod is lowered by sliding the upper and lower pins, so that the gap between the pins and the upper and lower pins is reduced. One flat needle sewing machine.
