Abstract

A detector provided on the upper shaft of a sewing machine for detecting the rotational speed of the upper shaft, the upper and lower positions of the needle, and the timing with which the thread is cut, which has a small size, is light in weight, has a high accuracy and has a readily adjustable detection position. This detector is constructed of a plurality of laminated photoelectric detection plates (24, 26, 28) on a coupling (10) secured to the upper shaft of the machine, each plate having a light shield disposed so as to superpose each other; light emitting means (40a, 42a, 44a, 46a) provided at one side of the plates for emitting light toward the plates (24, 26, 28); and photodetection means (40b, 42b, 44b, 46b) provided at the other side of the plates for receiving the light from the means (40a, 42a, 44a, 46a), and the state of the sewing machine can be detected by the reception of light by the means (40b, 42b, 44b, 46b). The plates (24, 26, 28) are pressed fixedly by compression means (30) in the axial direction of the coupling (10), thereby adjusting the plates (24, 26, 28) to predetermined angular positions.

In particular, in recent high-speed machines, there is a drawback that the rotating part or the magnet is damaged due to the large inertial moment. Furthermore, conventional detectors have the drawback that it is difficult to adjust and change the detection position of the detector, etc., according to the model or usage. ..

It is possible to prevent the lead wire 52 from coming off from the base 12.
¾ お ， 突起部 54は ， 第 5 図に示され る よ う に溝部 56の 下面 に設けて も ， 第 6 図に示 される よ う に溝部 56の側面 に設け て も よ い o - さ ら に本実施例では ， 力 ッ プ リ ン グ 10 と ベ ー ス と の対 向近接部において ， カ ッ プ リ ン グ 10には突出 リ ン グ 10c が設け られ ， ベ ー ス に は リ ン グ状の溝部 12b が設け られ てい る ので ， 対向近接部への糸の巻 き 込みを 防止で き る 。 すな わ ち ， 前記対向近接部が露出 して い る場合に は ， 縫製糸が 力 ッ プ リ ン グ 10近傍に たれ下が った と き ， その たれ下が り 端カ き わめ て容易に 力 ッ プ リ ン グ 10 と べ 了 リ ン グ 16 と の間 に巻 き 込ま れ ， 上軸の停止等の事故が発生 し ， ま た こ の よ う る巻 き 込み時に は ， ミ シ ン用検出器を 分解 して巻 き 込ま れた糸を取 り 出 さ る ければな らず ， き わめて面倒る作業が必要 と さ れる と い う 問題力 ¾> つ た。 これ に対 して ， 本実施例の よ う に ， リ ン グ状の溝部 12a と 突出 リ ン グ部 10c と に よ っ て二重の迷路を形成する こ と に よ り , 糸は こ の迷路を通 り 抜ける こ と がで き ず ， 前 記巻 き 込み事故をほぽ完全に 防止する こ と が可能 と る o な お 》 本実施例に よ れば ， 前記迷路を形成する ためにThe projection 54 may be provided on the lower surface of the groove 56 as shown in FIG. 5 or on the side surface of the groove 56 as shown in FIG. Furthermore, in this embodiment, the capping 10 is provided with the protruding ring 10c at the facing proximity portion of the force plug 10 and the base, and the base 10 is provided with the protruding ring 10c. Since the groove-shaped groove 12b is provided, it is possible to prevent the yarn from being wound into the facing proximity portion. In other words, if the above-mentioned facing proximity portion is exposed, if the sewing thread hangs down near the pulling 10, the hang-down of the sewn end will occur. It is easily caught between the pulling ring 10 and the observing ring 16, causing an accident such as the stop of the upper shaft. However, at the time of winding with a cocoon, it is necessary to disassemble the detector for the machine and take out the wound thread, which is a troublesome work. The problematic power was needed. On the other hand, as in the present embodiment, the double groove is formed by the ring-shaped groove 12a and the projecting ring 10c, so that the thread is It is not possible to pass through the maze, and it is possible to completely prevent the above-mentioned entrainment accident from happening. O According to this embodiment, in order to form the maze.
， 突出 リ ン グ部 10c が リ ン グ状の溝部 12 b 内 に入 り込ん でい る ため ， こ の よ う ¾迷路を形成 した場合において も , 軸方向 に対す る全体の厚さ を増加させる こ と が い と い う 利点を有する 。 ま た ， カ ッ プ リ ン グ 10に リ ン グ状の 溝部を設け ， ベー ス 12に突出 リ ン グ部を設けて も 同様の 効果を得る こ と カ で き る o Since the protruding ring part 10c is inserted into the ring-shaped groove part 12b, the total thickness in the axial direction is increased even when such a maze is formed. It has the advantage of being effective. It is also possible to provide the same effect by providing a ring-shaped groove on the coupling 10 and a protruding ring on the base 12.
以上説明 した よ う に , 本発明 に係る ミ シ ン用検出器に よ れば ， 小型 ， 軽量で あ り 高精度の検知作用 カ 行われカ つ検知位置の調整が容易 ミ シ ン用検出器を得る こ と が で き る 。  As described above, according to the detector for a machine according to the present invention, the detector for a machine is small in size, light in weight, has a highly accurate detection function, and can easily adjust the detection position.
