Description
【発明の詳細な説明】 本発明は、ミシンの送り歯高さ調整機構に関する。[Detailed description of the invention] The present invention relates to a feed dog height adjustment mechanism for a sewing machine.
従来から、主送り歯および副送り歯を備え、その差動比
を調節することができるミシンが提供さ′れているが、
主送り歯に対して、副送り歯の高さや前後の傾きを後調
整するのが困難であった。Conventionally, sewing machines have been provided which are equipped with a main feed dog and a sub feed dog and whose differential ratio can be adjusted.
It has been difficult to adjust the height and longitudinal inclination of the sub-feed dog relative to the main feed dog.
本発明は、か＼る事情に鑑みてなされたものであって、
主送り歯が固定された主送り台と副送り台とを偏心ビン
で連結せしめ、前記偏心ビンを回動することにより前記
副送り台を前記主送り台に対して変移できるようにし、
更に前記副送り台に副送り歯を上下動可能に取り付けて
、ミシンの送り歯調整機構を構成したものである。The present invention was made in view of the above circumstances, and
A main feed table to which a main feed dog is fixed and a sub-feed table are connected by an eccentric pin, and the sub-feed table is movable with respect to the main feed table by rotating the eccentric pin,
Further, a sub-feed dog is attached to the sub-feed table so as to be movable up and down, thereby configuring a feed dog adjustment mechanism of the sewing machine.
かくして、本構成によれば、
■ 偏心ビンを回動調整して、主送り歯を基準として副
送り歯の前後の傾きを微調整できる■ 偏心ビンの回動
調整と副送り歯の上下動とを併用することによって、副
送り歯の高さと主送り歯の高さとを同一にし・縫いピン
チを同一にし、縫じわ・縫ズレを防ぐことができる。Thus, according to this configuration, it is possible to: ■ Rotately adjust the eccentric bin and finely adjust the longitudinal inclination of the sub-feed dog with reference to the main feed dog; ■ Rotately adjust the eccentric bin and vertically move the sub-feed dog. By using these in combination, the height of the sub-feed dog and the height of the main feed dog can be made the same, the sewing pinch can be made the same, and seam wrinkles and misalignment can be prevented.

り台６と偏心ビン１６を介して一体化されているので、
副送り台７も同様に、略４辺形に近い周期運動をなす。To describe the operation of the above configuration, the first feed table 6 does not move horizontally reciprocating due to the swing of the horizontal feed shaft l, and the first feed table 6 does not move vertically through the feed arm 15 due to the swing of the vertical feed shaft 18. Since it makes reciprocating motion in the direction, the two motions are combined to form a periodic motion similar to a quadrilateral. Therefore, since the sub feed table 7 is integrated with the main feed table 6 via the eccentric bin 16,
Similarly, the sub-feed table 7 also makes a periodic motion close to a substantially quadrilateral shape.
したがって、主送り歯１８と副送り歯１９とが、周知の
布送り作用を行なう。Therefore, the main feed dog 18 and the sub feed dog 19 perform the well-known cloth feed action.

5 and eccentric positioning of the feed shaft 8. On the other hand, the sub-feed dog 19 has its elongated hole 19n inserted into the screw 21.
, and tighten the screw 21 at an appropriate position to set the approximate height.
You can make fine adjustments by rotating. Furthermore, the inclination of the sub-feed dog 19 in the front-rear direction can be easily performed by rotating the eccentric pin 16.
