Abstract

(57) [Summary] [Objective] To obtain a positioning device for an air spinning nozzle that can quickly and easily fix the air spinning nozzle in a fixed position when the air spinning nozzle is attached or detached. [Structure] The air spinning nozzle is attached to the nozzle holding member so that it can be adjusted forward and backward with respect to the front roller, and the positioning plate is attached to the nozzle holding member so that it can be adjusted forward and backward with respect to the front roller. By providing an engaging part for positioning on each, once the nozzle position is adjusted and the positioning plate is fixed, the nozzle can be removed.
When reattaching the nozzle, the nozzle can be easily set to its original position by simply aligning the engaging part of the positioning plate with the engaging part of the nozzle.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a positioning device for an air spinning nozzle for producing bound spun yarn.

0002

[Conventional technology]

Using compressed air, the air spinning nozzle consists of a first nozzle and a second nozzle. When obtaining a bound spun yarn, the number of yarns to be spun, yarn type, usage, etc. Accurately adjust the distance between the front roller pair of the foot device and the yarn introduction hole of the air spinning nozzle. There is a need to. After completing the adjustment and starting operation, the air spinning nozzle If the air spinning nozzle is damaged or requires replacement or maintenance, please After removing the air spinning nozzle, refill with new or maintained air. The spinning nozzle must be installed and fine adjustments must be made again, resulting in extra adjustment work. It required a lot of effort and time, and was extremely inefficient.

0003

[Problem that the idea aims to solve]

This idea allows for quick and easy positioning of the air spinning nozzle when attaching and detaching the air spinning nozzle. The purpose of this study is to obtain a positioning device for an air spinning nozzle that can be fixed in place. Ru.

0004

[Means to solve the problem]

The air spinning nozzle is attached to the nozzle holding member so that it can be adjusted forward and backward relative to the front roller. The positioning plate can be adjusted forward and backward relative to the front roller. It is attached to the nozzle holding member, and attached to the air spinning nozzle and the positioning plate respectively. An engaging part for positioning is provided.

[0005]

[Effect]

Once the nozzle position is adjusted and the positioning plate is fixed, the nozzle When removing the nozzle and reinstalling the nozzle, make sure that the engaging part of the positioning plate and the nozzle The nozzle can be easily set to its original position by simply aligning the nozzle with the engaging part of the nozzle. I can do it.

[0006] The front and back position of the air spinning nozzle can be determined by loosening the pressure on the presser plate and tightening the positioning plate. It is adjusted by moving forward and backward along the slit.

[0007]

【Example】

Hereinafter, embodiments of this invention will be described with reference to the drawings.

[0008] 1 and 2 are a pair of air spinning nozzles fitted into recesses 4 and 5 on the nozzle holder 3 and arranged side by side. It is attached to the front roller 16 so that it can move forward and backward. Also, the sky Concave grooves 6 and 7 are formed in the center of the air spinning nozzles 1 and 2 in the circumferential direction.

[0009] 8 is a positioning plate arranged between the air spinning nozzles 1 and 2 on the nozzle holder 3; As shown in FIG. 3, there is a slit 9 extending vertically in the center of the plate. , protrusions 10 and 11 are provided at centrally symmetrical positions on both side edges, respectively.

0010 The positioning plate 8 allows the screw 12 inserted into the slit 9 to be inserted into the nozzle. By screwing into the screw hole of holder 3, it can move forward and backward relative to the front roller 16. It is fixed to the nozzle holder 3.

[0011] 13 is a presser plate placed on the upper surface of the air spinning nozzles 1 and 2; Pass the tip of the screw 14 through the slit 9 of the positioning plate 8 and attach it to the nozzle holder 3. By screwing into the screw holes, the air spinning nozzles 1 and 2 are crimped and fixed from above. do.

0012 Therefore, when adjusting the position of the air spinning nozzles 1 and 2 from the state shown in Figure 1, Loosen screw 14 and remove presser plate 13, then loosen screw 12 and remove air spinning nozzle. The positioning plate 8 is moved back and forth along the slit 9 together with 1 and 2, and the air spinning nozzle is Accurately adjust the distance between the thread introduction ports 15 of wheels 1 and 2 and the front roller pair 16 to the required distance. Then, tighten the screws 12 to fix the positioning plate 8 to the nozzle holder 3, and then Screw together the screws 14 of the presser plate 13 placed on the spinning nozzles 1 and 2, and attach the air spinning nozzle 1. , 2 may be fixed to the nozzle holder.

[0013] Furthermore, either or both of the air spinning nozzles 1 and 2 should be replaced or maintained. When removing the presser plate 13, replace or maintain it in that state. Remove the air spinning nozzle to be maintained and install the new or maintained air spinning nozzle. Insert the convex part of the positioning plate 8 into the concave groove of the nozzle, and Once the presser plate is fixed, the yarn inlet 15 of the air spinning nozzle and the front roller pair 16, without readjusting the spacing, always keep the same spacing as before replacement. can be positioned.

[0014]

[Effect of the idea]

As described in detail above, the air spinning nozzle positioning device of this invention The nozzle is attached to the nozzle holding member so that it can be adjusted forward and backward relative to the front roller. The nozzle allows the positioning plate to be adjusted forward and backward relative to the front roller. attached to the air spinning nozzle and positioning plate, respectively. Since the nozzle is equipped with an engaging part for After fixing the rate, you can then remove the nozzle and reinstall the nozzle. The nozzle can be easily installed by simply aligning the engaging part of the positioning plate with the engaging part of the nozzle. You can simply set it back into place and replace the air spinning nozzle as before. Whenever replacement or maintenance is required, the yarn inlet and flap of the air spinning nozzle are There is no need to adjust the distance between the front roller pair and the extra labor required for adjustment work is eliminated. Recommends work to be done efficiently even by less skilled operators without requiring much force or time. I was able to
