Description
【０００１】[0001]
この考案は、針と釜との間隙を調整する機能を備えたジグザグミシンに関する ものである。 The present invention relates to a zigzag sewing machine having a function of adjusting a clearance between a needle and a shuttle.
【０００２】[0002]
ジグザグミシンでは、特に水平釜の場合は、釜の回転軸芯に針棒揺動台軸芯を 正確に合わせないと、針刺し位置における針と釜の剣先との隙間が適正なものに ならない。その隙間が大き過ぎると目飛びが発生し、隙間が小さ過ぎると、針擦 れを起こすことになる。そこでジグザグミシンにおいては、一般に、針棒揺動台 支えに支持され、先端がミシンフレームに当接されている調整用ネジを、ミシン の正面側より操作してその突出長を調整し、ミシン上方に設けられた支軸に対し て、針棒揺動台支えを前後方向に移動させることによって、針釜間の間隙調整を 行っている。 In the zigzag sewing machine, especially in the case of a horizontal hook, the gap between the needle at the needle stick position and the tip of the hook of the hook will not be correct unless the axis of the needle bar swing base is correctly aligned with the axis of rotation of the hook. If the gap is too large, skipping will occur, and if the gap is too small, needle rubbing will occur. Therefore, in a zigzag sewing machine, the adjusting screw, which is generally supported by the needle bar rocking support and whose tip is in contact with the sewing machine frame, is operated from the front side of the sewing machine to adjust the protruding length of the sewing machine. The needle bar oscillating base support is moved in the front-back direction with respect to the support shaft provided at the position to adjust the clearance between the needle hooks.
【０００３】[0003]
上記のジグザグミシンにおける針釜間の間隙調整は、正面カバー（フロントパ ネル）を取外してミシン正面から行わなければならず、その作業が大変である。 また、針棒揺動台支え全体をフレームに対して安定して固定することが困難であ る。 The above-mentioned zigzag sewing machine requires the front cover (front panel) to be removed from the front of the sewing machine to adjust the clearance between the needle hooks, which is a difficult task. Moreover, it is difficult to stably fix the entire needle bar rocker support to the frame.
【０００４】 この考案は、側面カバーを外すことによって簡単に針釜間の間隙を調整するこ とができ、その状態を固定することのできるジグザグミシンを提供することを目 的としている。The present invention aims to provide a zigzag sewing machine capable of easily adjusting the gap between the needle hooks by removing the side cover and fixing the state.
【０００５】[0005]
上記目的を達成するために、この考案のジグザグミシンは、フレームの上方及 び下方にそれぞれ固定し得る針棒揺動台支え支軸、偏心軸部を有する針棒揺動台 支え調整軸と、針棒揺動台を支持し、上部に貫通孔が穿設され、下部に溝を有す る針棒揺動台支えとよりなり、上記貫通孔に針棒揺動台支え支軸が挿通され、上 記溝に針棒揺動台支え調整軸の偏心軸部が係合し、調整状態を固定し得るもので ある。 In order to achieve the above object, the zigzag sewing machine of the present invention comprises a needle bar rocking base support shaft which can be fixed above and below the frame, and a needle bar rocking frame support adjusting shaft having an eccentric shaft portion. It consists of a needle bar rocking base support that supports the needle bar rocking base, has a through hole in the upper part, and has a groove in the lower part.The needle bar rocking base support spindle is inserted into the through hole. The eccentric shaft portion of the needle bar swing base support adjusting shaft engages with the above groove to fix the adjusted state.
【０００６】[0006]
上記のように構成されたジグザグミシンにおいては、一応のセットがなされた 後の針先と釜の剣先との前後方向の隙間調整が、針棒揺動台支え支軸に対して針 棒揺動台支えをゆるめ、針棒揺動台支え調整軸を回転させて、その偏心軸部の偏 心量を変化させ、最終的にその状態を固定することによってなされる。 In the zigzag sewing machine configured as described above, adjustment of the front-back clearance between the needle tip and the hook tip of the hook after the temporary setting is performed by adjusting the needle bar swing with respect to the needle bar swing base support spindle. This is done by loosening the platform support, rotating the needle bar swing platform support adjustment shaft, changing the amount of eccentricity of the eccentric shaft portion, and finally fixing the state.
