〔発明の目的〕
（発明の対象）
本発明は環縫ミシンの空環切断装置に関するものである
。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Object of the Invention) The present invention relates to an empty chain cutting device for a chainstitch sewing machine.
（従来の技術）
従来、多針二重環縫ミシン等で連続して縫われたｍ製物
の学理部分（ツナがり部）切り離しは、例えば鋏による
手操作切断、又は当該部を加熱手段により溶断したもの
である。(Prior art) Conventionally, the mechanical part (edge part) of a product that has been sewn continuously using a multi-needle double chainstitch sewing machine or the like can be separated by manual cutting with scissors, or by heating the part. It was fused.
（発明が解決しようとする問題点）
上記従来の切断手段で鋏による場合は、煩瑣な手間を要
し、溶断による場合は連続する製品を保護するため、縫
製布間の間隔を比較的長くとりその中間の空環縫部を加
熱溶断した。従って相互の縫製布間に長い空環の切れ端
が残り、後工程の縫製時にこの空環端が表面側に縫い出
され易く、完了後の仕上としてこの空環端を鋏等により
切断する無駄な作業が行なわれた。(Problems to be Solved by the Invention) When using scissors as the conventional cutting means described above, it requires a lot of effort, and when using fusing, the intervals between the sewn fabrics are relatively long in order to protect successive products. The empty chain stitched portion in the middle was heated and fused. Therefore, a long piece of the empty ring remains between the sewing fabrics, and during the subsequent sewing process, the end of the empty ring is likely to be sewn out to the front side, making it unnecessary to cut the end of the empty ring with scissors etc. work was done.
本発明では、空環部を溶断する際、連続する前後の布端
を焼損することなく、その間隔を熱線が当接する僅少な
範囲にとどめ得、しかも連続的に溶接を可能とするよう
な手段達成を計ったものである。In the present invention, when cutting the hollow ring part, the continuous front and back ends of the cloth are not burned out, and the distance between them can be kept within a small range where the hot wire contacts, and furthermore, it is possible to weld continuously. It is a measure of achievement.
（問題点を解決するための手段） 本発明では、連続する二つの製品の空環縫部。 (Means for solving problems) In the present invention, the empty chain seam portion of two consecutive products is used.
線間隔を機械的、光学的に調節、検出せしめ、この検出
信号で電気的に熱線を上下動させた。The distance between the wires was adjusted and detected mechanically and optically, and the detection signal was used to electrically move the hot wire up and down.
（作用）
而して、この熱線は保護部材（例えば環状巻形コイル）
内の中心に張設保持され、該保護部材で布端の焼損を防
止し、空環糸は上昇した前記コイル巻線のピ・ンチ間隙
を通して熱線に当接し、溶断されるようにした。(Function) Therefore, this hot wire can be used as a protective member (for example, a circularly wound coil).
The protective member prevents the ends of the cloth from being burnt out, and the hollow ring yarn comes into contact with the hot wire through the pinch gap of the raised coil winding and is fused and cut.
（実施例） 第１〜２図において、１は熱線にクロム線。(Example) In Figures 1 and 2, 1 is a chrome wire as a heating wire.

Reference numeral 5 denotes electrical and thermal insulators provided on the left and right sides, which are fixed to the support member 7 with bolts 6. A hot wire 1 is connected to this support member 7 via the insulator 5.
is installed under tension, and a protective member (an annular wound coil illustrated in the figure) 8 that covers the hot wire 1 is fixed with a screw 10 via a mounting base 9. A connecting plate 11 is fixed to the support member 7 with screws 12, and is opposed by an air cylinder 13 serving as a drive line provided on the sewing machine bed side.

ブである。The numerals 14 and 15 are air elbows, and the numerals 16 and 17 are above arms for lowering and raising the heating wire, respectively.
また第３図示する１８は縫い直後の製品、１８ａ −ｄ

環部、２０は後続縫い製品である。In addition, 18 shown in the third figure is a product immediately after sewing, 18a - d
19 is a needle thread pattern (JIS-4,01 type), 19 is an empty ring part, and 20 is a subsequent sewing product.
本発明装置は、これをミシンテーブルの縫い送り方向前
方（好ましくは前方端付近）に設けると縫製後の製品は
連続して空環部を溶断された後、適宜にＭ積される。When the device of the present invention is installed at the front of the sewing machine table in the sewing feed direction (preferably near the front end), the sewing products are continuously melted at the empty ring portions and then piled up in M as appropriate.
尚、第４図はエアシリンダが上昇した場合の局部断面を
示し、第５及び６図は保護部材の変形例を示す。Note that FIG. 4 shows a local cross section when the air cylinder is raised, and FIGS. 5 and 6 show modified examples of the protection member.
本発明空環切断装置は上記の如く構成し作動するので、
縫製後の製品に空環の残り量が僅少となり、後始末に要
する手間が省けると共に連続したｌ製品切り離しができ
て、縫製作業の合理化に役立つところが大である。Since the empty ring cutting device of the present invention is constructed and operates as described above,
There is only a small amount of empty rings left on the product after sewing, which saves the effort required for cleaning up afterward, and also allows continuous product separation, which is very useful for streamlining the sewing work.
