Description
本新型係有關一種縫紉機之隱藏式切線裝置,尤指一種作動機構不外露,且非連續作動的切線裝置 。The present invention relates to a hidden tangential device for a sewing machine, and more particularly to a tangential device in which the actuating mechanism is not exposed and is not continuously actuated.
目前應用於縫紉機之切線裝置,有如新型專利第M481242號「包縫針車之縫線裁剪裝置」,係設有一組立板,固定於包縫縫紉機之機台上,該組立板上設有頂推動力源,並使該頂推動力源之傳動軸與活動刀桿連接,且於該組立板上裝置一固定刀板,令該活動刀桿及固定刀板之刀刃部相對應,另於該組立板設有一夾掣平台,並設有一遮蓋,覆蓋於該活動刀桿之刀刃部上方,另於該遮蓋側邊成型一縫線定位口,令該縫線定位口位於與該活動刀桿及固定刀板之刀刃部相接處。At present, the tangential device applied to the sewing machine is similar to the new patent No. M481242, "Sewing-cutting device for overlock sewing machine", which is provided with a set of vertical plates fixed on the machine of the overlock sewing machine, and the set of vertical plates is provided with a top driving force. a source, and connecting the drive shaft of the top driving force source to the movable cutter bar, and fixing a fixed blade on the set of vertical plates, corresponding to the blade edge of the movable cutter bar and the fixed blade, and the set of vertical plates a clamping platform is provided, and a cover is arranged to cover the blade edge of the movable cutter bar, and a suture positioning port is formed on the cover side, so that the suture positioning port is located with the movable cutter bar and the fixed knife The blade edge of the board meets.
上述習知之裁剪裝置,操作者於車縫完一工作物後,必須將縫線拉引至遮蓋縫線定位口,此時,頂推動力源接受到訊號驅動該連桿,以推動活動刀桿,而使該活動刀桿之刀刃部朝固定刀板之刀刃部方向位移,以將縫線裁斷,而使該縫線與車縫工作物分離。In the above conventional cutting device, after the operator finishes sewing a work object, the operator must pull the suture to cover the suture positioning position. At this time, the top driving force source receives the signal to drive the connecting rod to push the movable arbor. And the blade portion of the movable blade is displaced in the direction of the blade portion of the fixed blade to cut the stitch to separate the stitch from the sewing work.
惟上述之操作,操作者必須以徒手方式,將縫線拉引至遮蓋縫線定位口,操作者因此必須停止車縫工作,而使車縫作業中斷;另外,該用以聯動活動刀桿之頂推動力源及其連桿等機構,是曝露於外,操作者在徒手將縫線拉引至遮蓋縫線定位口的過程中極易與這些機構碰撞,造成受傷,也顯有改進的必要。However, in the above operation, the operator must pull the suture to cover the suture positioning position in a freehand manner, so the operator must stop the sewing work and interrupt the sewing operation; in addition, the linkage is used to interlock the movable arbor. The mechanism of the top driving force source and its connecting rod is exposed, and the operator easily collides with these mechanisms during the process of pulling the suture to cover the suture positioning hole by hand, causing injury and obvious improvement. .
