As a device for detecting the amount of bobbin thread remaining in conventional sewing machines,
There is a publication No. 56-42959. This device allows a movable flange to slide on the axial cylinder part of a fixed flange, and determines whether light emitted from a light emitting diode is received by a phototransistor on the surface of the movable flange.The configuration of the bobbin is as follows: , a cylindrical pipe protrudes from inside the movable flange.

In this conventional bobbin thread remaining amount detection device, if the bobbin thread is initially wound around the cylindrical pipe projected inside the movable flange, the movable flange will move toward the fixed flange, and the operator will be warned. The amount of bobbin thread becomes too small, and the goal is to make sure to notify the user before the thread in the bobbin runs out.
Helps the sewing work proceed smoothly. ” may not be fully achieved. Therefore, when winding the bobbin thread around the bobbin, it has to be wound from the smallest diameter part, and the operator has to be careful in winding each bobbin one by one.

The technical means works as follows. That is, no matter where you start winding the bobbin thread onto the bobbin of the device of the present invention, the bobbin thread will slip from either the truncated conical portion 11 of the fixed flange 1 or the truncated conical portion 22 of the movable flange 2.
It falls into the concave groove 12 of the fixed flange and comes into close contact with it, and winding can be started from there. The bobbin thread is gradually wound, and the movable flange 2 is pushed by the wound bobbin thread and moves to a position where it is stopped by the retaining ring 3, and the thread is wound thereon (Fig. 5). From this state, the bobbin thread As the thread is consumed, as shown in FIG. 3, the bobbin thread remaining in the groove 12 of the fixed flange 1
If the movable flange 2 protrudes even slightly from the outer peripheral surface of the shaft cylindrical portion 13, the movable flange 2
The light emitted from the light emitting diode 17 inserted in the detection part 15 is reflected on the side surface of the movable flange 2 because it cannot slide on the shaft cylinder part 13 and is in a fixed position. The angle of reflection of the light emitted from the light emitting diode 17 is such that the position of the movable flange 2 can be confirmed at all times by being received by the phototransistor 18 inserted in the phototransistor 18. θ, FIG. 4 shows a case where a small amount of bobbin thread remains in the groove 12 provided in the fixed flange 1, and the movable flange 2 presses the axial cylinder portion 13 of the fixed flange 1 against the pressing spring (see FIG. (not shown), the reflection angle of the light emitted from the light emitting diode 17 inserted into the detection section 15 increases to θ', and the phototransistor 18 cannot receive the light and the remaining amount of the bobbin thread decreases. The system notifies the operator of the replacement.

The present invention produces the following unique effects. In other words, there is no need to pay much attention to the position at which to start winding the bobbin thread, and winding can be started automatically from any predetermined position, just like a conventional bobbin, and the remaining bobbin thread length is small. Since a certain amount of time is secured, when the notification is received in the middle of sewing, it is possible to know how much time is left to be sewn, and the sewing work can proceed smoothly. Furthermore, when used with a horizontal rotary hook equipped with an automatic bobbin winding device, the bobbin of the present invention can be even more effective because the bobbin winding start is always inserted into the groove.

The fixed flange 1 has a flange portion 1 from one end,
A truncated conical portion 11, a concave groove 12, a shaft cylinder portion 13, and a retaining ring groove 14 into which the retaining ring 3 is fitted are arranged in a row, and the movable flange 2 has a flange portion 21 and an inclined portion 22. Furthermore, the movable flange 2 is slidably inserted onto the axial cylindrical portion 13 of the fixed flange 1, and then the retaining ring 3 is inserted into the retaining ring groove 14 provided at the tip of the axial cylindrical portion 13 of the fixed flange 1. The movable flange 2 is assembled so that it does not fall off. The tips of a light emitting diode 17 and a phototransistor 18 are integrally fitted in the detection unit 15 with an angle maintained at θ°, and the incident angle of the light emitted from the light emitting diode 17 and the side surface of the flange portion 21 of the movable flange 2 are set. The phototransistor 18 is mounted so that the reflection angle at which the phototransistor 18 receives light is the same. When the bobbin thread is sufficiently wound around the bobbin, the clearance between the side surface of the flange portion 21 of the movable flange 2 and the end surface of the shaft cylinder portion 13 of the fixed flange 1 is X.
When there is a shortage of bobbin thread and a notification is required, the dimension X increases to X'.
