The present invention relates to a device for stopping the irradiator.

Conventionally, such a device is engaged with a tension sensing lever 3 which is rotated by the tension of thread 2 passing through the pulley 1 mounted at one end as shown in FIG. When the brake pin 5 is formed, and the stop shaft 6 is rotated with the support shaft of the intermediate part as a point, and abnormal tension is generated in the thread 2 under irradiation, the tension sensing lever 3 is rotated in the direction of the arrow 7 and the tension The engagement between the sense lever 3 and the stop lever 6 is released. As the stop lever 6 rotates in the direction of the arrow 8 by its own weight, the brake piece 5 is brought into contact with the uple 4 and subjected to flow by the rotation of the Y-axis of the wheel 4, so that the brake piece 5 at the tip is elastically deformed. The contact pressure with the spool 4 increases, and accordingly the frictional force with the spool 4 increases, so that the brake piece 5 and the spool 4 come into contact with each other at the position slightly smaller than the line X connecting the axis of the stop lever 6 and the center of the spool 4. A stopper 9 was installed to stop four. According to the configuration described above, the frictional force between the wheel and the brake piece is maximized, and the time until the wheel stops is the shortest, but the center angle of the wheel and the axis of the stop lever are intermittently disengaged. Since the contact position with the X-ray (in detail, the shortest distance between the center of the wheel 4 and the shaft of the stop lever 6), the stop lever cannot follow the deviation of the wheel, and the engagement between the wheel and the brake piece is peeled off for a moment. As a result, there is a drawback that the spool causes blackout or reversal, resulting in sagging threads, or thread entanglement.

The present invention, in view of the shortcomings of the conventional apparatus as described above, the shaft or shaft of rotating the wheel according to contact with the wheel in the rear position of the wheel than the line connecting the center of the wheel and the support shaft of the stop lever. The present invention provides an apparatus for stopping an irradiator that can stop the dust surely even if the shaft insertion hole is bent or deformed.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 2, the irradiator 10 extracts silk thread 13 from the plurality of cocoons 12 in the irrigation bath 11 and passes through a pipe 15 of the rotary dish machine 14 installed on the outer circumference. The thickness is measured by a denier (not shown) which measures the thickness of yarns after appropriately combining by kennel 18 formed using pulleys 19 and 20. After the reversal, the guide rail 23 is traversed by the guide 23 with the pulley 22 mounted on one end of the tension sensing lever 27 and wound around the shaft 25 friction-fitted to the rotation shaft 24.

At the other end of the tension sensing lever 27 on which the pulley 22 is mounted, an arcuate engagement portion 28 engaged with the roller 32 mounted on one end of the stop lever 29 described later is formed. The stop lever 29 is composed of a first lever 30 and a second lever 31. The roller 32 is provided at one end of the first lever 30, and the other end is pivotally mounted on the support shaft 33.

In addition, the second lever 31 is pivotally pulled on the support shaft 33, and a brake piece 34 made of an elastic material such as rubber that comes into contact with the lever 25 is fixed to one end of the lever 31.

Moreover, the spring 36 which always adds the said 2nd lever 31 and the 1st lever 30 to arrow 35a and 35b direction is formed, respectively, The said 2nd lever 31 is predetermined by the stop piece 37,38 formed in the 1st lever 30, It is possible to rotate as much as the range. 39 is a stopper for coming into contact with the first lever 30 to stop the rotation of the stop lever 29 at a predetermined position.

Since the present invention has the configuration as described above, when the thread tension under irradiation is appropriate, as shown in Fig. 3, the engaging portion 28 of the tension sensing lever 27 and the roller 32 of the first lever 30 engage with each other to brake the second lever 31. Judges 16 are in turn encircled by tales 25, since they are separating section 34 from tales. However, when abnormal tension is generated in thread 16 during irradiation, the tension sensing lever 27 is rotated in the direction of the arrow 40 by the tension of thread 16, so that the roller 32 of the first lever 30 and the engaging portion 28 of the tension sensing lever 27 Is released, and the stop lever 29 is rotated in the direction of arrow 41 by its own weight. When the brake piece 34 and the shaft 25 of the second lever 31 tip come into contact with each other, the stop lever 29 is rotated in the direction of arrow 41 by the induction action by the rotation of the wheel 25. However, the first lever 30 is prevented from rotating by the stopper 39, and the second lever 31 is rotated in the rearward position, which is rotated 25 times from the connecting line x of the spring 36 around the support shaft 33, and engages with the stop piece 38. Is stopped. Accordingly, the second lever 31 receives the rotational force in the direction opposite to the arrow 41 by the spring 36, and the brake piece 34 contacts the ring 25 by this rotational force to stop it. In addition, the contact point A of the brake piece 34 and the rim 25 is located at the rearward position of the rim 25 than the intersection point B between the center of the rim 25 and the center of the support shaft 33 of the stop lever 29 and the main axis of the rim 25. Since the point A approaches the center of the shaft 25 (in detail, the vertical line of the line X in the shaft center) by the length H than the point B, as shown in Fig. 4, the point A of the shaft 24 or the shaft insertion hole of the shaft If the deviation of the dust 25 generated by the deformation is up to H, the brake piece 34 can follow the deviation of the ice 25, and can prevent a power failure or reversal during the operation of the dust stop device.

Therefore, there is an advantage of preventing accidents such as thread trimming, sagging of yarn, or entanglement of yarn. In addition, in the above-described embodiment, an example in which the stop lever is divided into two parts has been described. However, the present invention is not limited thereto. In the rear position where the wheel is rotated, the brake piece and the wheel are brought into contact with each other, and the stop lever may be added to the wheel by a spring or the like.
