The illuminator 62, the light receiver 63, and the mirror surface 64 are disposed outside the circumference of the yarn 10.

When the roller attachment member 20 is in the second attachment posture as shown by the one-dot chain line in FIG. 3, the plate 25 (second light shielding portion 20c-2) shields the light 61.

When the roller attachment member 20 is in the third attachment posture as shown by the two-dot chain line in FIG. 3, the horizontal plate 24 (the first light blocking portion 20c-1) shields the light 61.

That is, the first attachment posture of the roller attachment member 20 is a posture in which the light 61 of the photoelectric sensor 60 is not shielded.

The second mounting posture and the third mounting posture of the roller attachment member 20 are postures that shield the light 61 of the photoelectric sensor 60 and the photoelectric sensor 60 outputs a signal.

By applying the downward first force F1 to the guide roller 15 by the tension of the core wire 4, the roller attachment member 20 applies a force that swings to one side in the left-right direction around the swing center 20a-1 by the first force F1.

The force that swings the mounting member 20 to one side in the left-right direction by the first force F1 when the tension of the core wire 4 is a predetermined size is larger than the swinging force applying unit 40 (weight) 41) A force that swings the attachment member 20 to the other side in the left-right direction.

Thereby, when the tension of the core wire 4 is a predetermined size, the roller attachment member 20 abuts against the stopper unit 50, and the roller attachment member 20 is maintained in the first attachment posture.

When the tension of the core wire 4 is smaller than a predetermined size, for example, when the tension is zero, the roller attachment member 20 is swung in the second mounting posture by the swing urging unit 40.

The predetermined tension of the core wire 4 is the magnitude of the tension applied to the core wire 4 in a state where the core wire 4 is normally taken out from the core bobbin 2 and the core wire 4 is normally supplied.

The second force F2 toward the rear side in the front-rear direction is applied to the inlet guide roller 15 by the tension of the core wire 4.

The second force F2 when the tension of the core wire 4 is a predetermined size is smaller than the force at which the holding unit 30 holds the roller attachment member 20 at the first position. When the tension of the core wire 4 is a predetermined size, the roller attachment member 20 is held by the holding unit 30. In the first position.

The second force F2 when the tension of the core wire 4 is larger than the predetermined size is larger than the force at which the holding unit 30 holds the roller attachment member 20 at the first position, and the roller attachment member 20 moves to the second position against the holding unit 30.

Accordingly, when the core wire 4 is normally supplied to the mandrel 3, the roller attachment member 20 is in the first mounting posture, and the light shielding portion 20c of the roller attachment member 20 does not shield the light 61 of the photoelectric sensor 60. Thereby, the photoelectric sensor 60 does not output a signal.

If the core bobbin 2 has no core wire 4, the tension of the core wire 4 is not applied to the inlet guide roller 15.

Thereby, the roller attachment member 20 is moved to the second mounting posture by the swing urging unit 40. The potential swings, and the plate 25 (the second light blocking portion 20c-2) shields the light 61 of the photoelectric sensor 60, and thus the photoelectric sensor 60 outputs a signal.

In the case where the winding of the core wire 4 is generated on the core wire supply path 5 between the core bobbin 2 and the mandrel 3, the tension of the core wire 4 is larger than a prescribed size.

Thereby, the roller mounting member 20 resists the holding unit 30 and moves to the second position by the second force F2 applied to the inlet guide roller 15, the roller mounting member 20 is spaced apart from the stopper unit 50, and the roller mounting member 20 is applied by application. The first force F1 to the inlet guide roller 15 swings in the third mounting posture, and the horizontal plate 24 (the first light blocking portion 20c-1) shields the light 61 of the photoelectric sensor 60, so that the photoelectric sensor 60 outputs a signal. .

Accordingly, the coreless wire 4 on the core bobbin 2 can be detected by the signal output from the photoelectric sensor 60. Further, by the signal output from the photoelectric sensor 60, the core wire 4 on the core supply path 5 between the core bobbin 2 and the mandrel 3 can be detected to be wound.

In the embodiment, the display unit 70 such as a lamp, a buzzer, and a sound generator is attached to the outside of the cover 8, and the display unit 70 is actuated by the signal output from the photoelectric sensor 60 to activate the display unit 70. The operator can sense that the coreless wire 4 on the core bobbin 2, or the core wire 4 on the core wire supply path 5 is wound.

The signal from the photoelectric sensor 60 is input to a controller that stops the continuous zipper fastener manufacturing machine.

In the embodiment, the inlet guide roller 15 is attached to the roller attachment member 20, but the auxiliary guide roller or the outlet guide roller 17 may be attached to the roller attachment member 20.

That is, it is only necessary to attach the guide roller of the core supply path 5 to the roller attachment member 20.

The attachment portion 20a of the roller attachment member 20, the roller attachment portion 20b, and the light shielding portion 20c may be integrated, and the roller attachment portion 20b and the light shielding portion 20c may be integrated.

In the embodiment, the light 61 of the photoelectric sensor 60 is reflected by the mirror 64 and received by the light receiver 63. However, the light 61 of the illuminator 62 can be directly received by the light receiver 63.

That is, the photoelectric sensor 60 outputs a signal by shielding the light 61. In the case of the light 61, a light beam of a phototube, laser light, or the like is used.

The light sensor 61 can also receive the light 61 by the photodetector 63 of the photoelectric sensor 60, and the photoelectric sensor 60 performs a detection operation to output a signal.

For example, as shown in FIG. 7, the first mirror surface 65 is attached to the plate 25 of the roller mounting member 20, and the second mirror surface 66 is attached to the horizontal plate 24.

When the roller attachment member 20 is in the first mounting posture, the first mirror surface 65 and the second mirror surface 66 are located below the light 61 illuminated by the illuminator 62, and the light 61 is not reflected, so that the light receiver 63 does not receive the light 61.

Thereby, the photoelectric sensor 60 does not perform the detection operation.

When the roller attachment member 20 is in the second attachment posture, the first mirror surface 65 moves upward, and the light 61 emitted from the illuminator 62 is reflected by the first mirror surface 65, and the light receiver 63 receives the light 61.

Thereby, the photoelectric sensor 60 performs the detection operation and outputs a signal.

When the roller attachment member 20 is in the third attachment posture, the second mirror surface 66 moves upward, and the light 61 emitted from the illuminator 62 is reflected by the second mirror surface 66, and the light receiver 63 receives the light 61.

Thereby, the photoelectric sensor 60 performs the detection operation and outputs a signal.

The detecting unit is not limited to the photoelectric sensor 60. For example, it can be set as a proximity switch or the like.

In each of the embodiments, when the tension of the core wire 4 wound around the inlet guide roller 15 is smaller than a predetermined size, the roller attachment member 20 swings in the second attachment posture, and when it is larger than a predetermined size, the roller attachment member 20 swings in the third attachment posture. However, when the tension of the core wire 4 is smaller than a predetermined size and larger than a predetermined size, it may be swung in the second mounting posture or the third mounting posture.
