この考案は、縫製動作終了後、被縫製物に連結されてい
る上糸を切断する上糸切断装置に関し。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] This invention relates to a needle thread cutting device that cuts a needle thread connected to a workpiece after a sewing operation is completed.
特に1強度の高い極太の糸を用いた場合に好適なミシン
の上糸切断装置に関するものである。The present invention relates to an upper thread cutting device for a sewing machine that is particularly suitable when using a very thick thread with high strength.

断するようにしたものが一般に知られている。[Prior Art] Currently, sewing machines are equipped with a thread cutting device that automatically cuts the thread after the sewing operation is completed. This thread trimming device is equipped with a plate-shaped fixed blade installed on the side of the 1M-long sewing path, and a movable blade that overlaps the upper surface of the fixed blade. It is generally known that the movable blade is moved forward to cross the lifting path to capture the thread, and then the captured thread is pulled out to the side by the backward motion of the movable blade and sheared between it and the fixed blade. ing.

こともあった。This is especially noticeable when extremely thick or strong threads are used. For example, in recent years, when sewing air hacks that are attached to cars, threads that are extremely thick compared to those used for sewing clothes, etc. When a conventional thread cutting device is used to cut such threads, the fixed blade and movable blade deteriorate in a very short period of time and must be replaced with new ones frequently. In some cases, the thread was inserted between the fixed blade and the movable blade without being cut, resulting in poor cutting.

押えKとワークW間て切断される。Looking at the operation during this time in Fig. 2, as the cylinder S expands, the upper thread cutting means A is guided by the guide means B from its original position and moves to the lower left in the figure. , the fixing member 1 is located below the presser foot K, with the upper thread 9 in between.
b and the movable member 1al are in an open state. (5th
(See figure) Then, in the state shown in Figure 5, the piston P
When extended, the locking portion 7a at the tip of the stopper 7
The movable member 1a engages with one (upper in the figure) rising end of the shaft support 1al of the movable member 1a.
It rotates clockwise around P, so that the apex of the cutting member 2 comes into contact with the needle thread 9, and then the movable member 1a or the needle thread 9 is held between the fixed member 1b and the cutting member 2. At the same time as the point In contacts the upper thread 9, the cutting member 2 is energized, and the upper thread 9 is cut between the presser foot K and the workpiece W due to the Joule heat generated at the apex.
なお、この通電は、エアシリンダSの作動タイミングに
より上記タイミングて開始されるようあらかしめタイマ
が設定される。Note that a preliminary timer is set so that this energization is started at the above-mentioned timing according to the operation timing of the air cylinder S.
そして、糸の太さ等に応してタイミングを前後するよう
作業者か調節可能である。Then, the operator can adjust the timing back or forth depending on the thickness of the thread, etc.
この後、切断された上糸9の側N側端部を挟持した状態

の動作により抜脱される。During this time, with the exit of the upper thread clamping mechanism 1, the holding member 8 of the upper thread feeding means C also returns to its original position, and when the next sewing process is started, the upper thread end held by the upper thread clamping mechanism 1 is Needle N
It is removed by the action of
以降、上述の動作を繰り返す。Thereafter, the above-mentioned operation is repeated.
なお、この実施例て、切断部材2は、第3図に示すよう

発生することもなく耐久性か著しく向上する。In addition, in this embodiment, as shown in FIG. 3, the cutting member 2 has a very small vertex that comes into contact with the needle thread.
When energized, this part instantly becomes red hot and allows for quick cutting operations, but since it has a U-shape as a whole, it does not "sag" due to repeated contact with the upper thread. This does not occur and the durability is significantly improved.
