Here, when one drive shaft 55 is connected to the other drive shaft 61, the coupling 59 and the couplings 39 and 43 support the main body 9, so that the main body 9 is supported. It plays a role of stopping rotation so as not to rotate.

As shown in FIG. 2 and FIG. 3, the worm wheel 51 which is an example as a driven transmission member is attached to the housing 11. The worm 53 is engaged with the worm wheel 51 as a drive transmission member provided in the main body 9. On this worm 53, one rotatable drive shaft 55 extending in the horizontal direction in FIG. 2 is rotatably supported in the main body 9 via a bearing 57. In FIG. 3, the cover 75 is coupled to the rear of the main body 9 with a plurality of bolts 77 (see FIG. 1) via a collar 73 on the right side of the worm wheel 51. In addition, the worm wheel 51 and the worm 53 are made of a material that does not rust, such as stainless steel, brass, brass, or the like.

Next, a fluid processing method of the seal using the fluid processing apparatus 1 will be described.

In Fig. 1, a core yarn C1 and an entanglement yarn E1 are drawn out from a supply package (not shown) and sent out to feed rollers 45 and 47, respectively. Examination C1 sent out to this supply roller 45 receives the water heated by the water provision part 17 of the water provision nozzle 15 via the thread guide 19. As shown in FIG. The examination C1 which received water is sent to the core 13 of the nozzle 7 via the guide 25.

On the other hand, liquid, for example water, is discharged from the fluid supply source (not shown) by the pump and sent to the nozzle 15 through the pipe 29. In addition, the compressed air is discharged from the compressed air supply source (not shown), and is provided in the core 13 of the nozzle 7 through the supply holes 35 through the pipes 41 and 37 and again through the fluid chamber 33. It is supplied to the injection hole 31.

Then, when compressed air is sent from the pipe 41 to the fluid chamber 33 via the supply hole 35, the compressed air is injected into the thread introduction hole 13H of the core 13 from the plurality of injection holes 31. do. The screening C1 and the outer layer yarn E1 supplied into the thread introduction hole 13H of the core 13 are processed by compressed air, and the bulky yarn having a uniform loop, entanglement or loose portion in the longitudinal direction ( Y1) is obtained. The bulky yarn Y1 is wound around a winding roller (not shown) via a delivery roller (relax roller) 49.

Here, when the motor 71 is driven, the pulley 65 is rotated through the shaft 69. As the pulley 65 is rotated, the drive shafts 61 and 55 are rotated through the belt 67 and the pulley 63 and the housing 11 is rotated through the worm 53 and the worm wheel 51. do. Since the core 13 is provided in the housing 11, it rotates with the housing 11 in the arrow direction of FIG.

At this time, the screening C1 and the outer layer yarn E1 introduced from the thread introduction hole 13H are fixed at a predetermined place on the inner wall of the core 13 and do not travel, but always move the inner circumference on the inner wall of the jet core 13. Along the road.

That is, when dirt, such as yarn oligomer of screening C1 and outer layer yarn E1, is going to adhere to the inner wall of the thread introduction hole 13H in the core 13, rotation of the housing 11 and the core 13 is carried out. By this, the screening C1 and the outer layer yarn E1 are not always fixed to a certain place of the core 13, but move along the inner circumference at the inner wall of the thread introduction hole 13H in the jet core 13, have. Therefore, even if the dirt adheres to the inner wall of the thread introduction hole 13H in the core 13, the dirt is removed when the screening C1 and the outer layer yarn E1 pass through the attachment place again. And since the washing | cleaning period of the nozzle 7 can be made longer than before, no dirt adheres to the inner wall of the seal introduction hole 13H in the core 13, and productivity can be improved. In addition, since the dirt hardly adheres to the inner wall of the thread introduction hole 13H in the core 13, the variation in the running tension between the screening C1 and the outer layer yarn E1 becomes smaller than before. Therefore, since a stable process is performed, the favorable bulky yarn in which the quality of a yarn was stabilized can be obtained.

Moreover, the worm wheel 51 is attached to the housing 11, and the worm 53 which transmits rotation to the said worm wheel 51 in the main body 9 is provided. Therefore, maintenance of the nozzle 7 itself can be performed easily, and operability and handleability are improved, and thread hanging operation is improved. In addition, the overall structure is simplified.

Moreover, rotation of the other drive shaft 61 provided in the support member 5 is transmitted to the worm 53 via one drive shaft 55 provided in the main body 9, and also the worm wheel 51 Since the nozzle housing 11 is rotated through, the nozzle core 13 is rotated. When the compressed air is supplied to the other pipe 41 provided on the support member 5, the compressed air is supplied to the fluid supply hole 35 as a compressed fluid passage through one pipe 37 provided on the main body 9. And is injected into the core 13 through the injection hole 31.

In addition, since the other drive shaft 61 and the pipe 41 are connected to one drive shaft 55 and the pipe 37 so as to be detachable at about the same time, the main body 9 is connected to the support member 5. It is easily separated by one operation.

Since the core 13 is easily separated from the housing 11, the jet core can be easily changed every time various kinds of yarns are processed.

In addition, since the driven transmission member and the drive transmission member are the worm wheel 51 and the worm 53, respectively, the rotational movement can be easily transmitted to the housing 11 even with a simple mechanism.

In addition, as the rotation means for rotating the housing 11, the worm wheel 51 is mounted to the housing 11, and the worm 53 is attached to the pulleys 63 and 65, the belt 67 and the driving motor 71. It rotates by using, but it is also possible to rotate the worm 53 by the sprocket, the chain and the drive motor. Alternatively, gears may be used in place of the worm wheel 51 and the worm 53, respectively. Rotation of the housing 11 may be rotation other than one direction, and may be made to perform reverse rotation. In addition, the fluid processing apparatus 1 can process a thread even if it does not have a liquid imparting means. The fluid processing apparatus and the fluid processing method of this embodiment may be used in addition to other types of yarn processing machines.

Moreover, synthetic fibers, such as polyester fiber other than the stretched yarn of nylon, are also applicable to the thread of this embodiment, A semi-stretched yarn and an unstretched yarn may be sufficient. It is also applicable to single processing of single yarn that does not use both screening and outer yarn.

<Example>

Nylon 6 FDY70D-24F was used for the screening (C1) and the outer layer yarn (E1), respectively, to speed the thread 400 m / min, the overfeed of the screening (C1) + 35%, and the nozzle housing 11 Under the conditions of one rotation of 30 seconds, the compressed fluid treatment was performed with the air processor (fluid processing apparatus) 1 shown in FIG.

As a result, the conventional nozzle cleaning timing was performed once every 1 day to 1.5 days, so that in this embodiment, replacement was performed once every 4 to 5 days. That is, the cleaning time of the compressed fluid treatment nozzle 7 can be delayed 3-4 times compared with the prior art. Therefore, productivity was significantly improved compared with the past. In addition, the safety of processing and the safety of real quality were able to obtain a uniform bulky yarn almost unchanged from the conventional.

In addition, this invention is not limited to embodiment of above-mentioned invention, It can implement in other forms by making an appropriate change. In the present embodiment, an example in which water is applied to the screening C1 by the water imparting nozzle 15 as the liquid imparting means has been described, but the present invention can be implemented even without the water imparting nozzle 15. In addition, although core processing using the screening C1 and the outer layer yarn E1 has been described, it is also possible to perform single processing using only the screening C1.

According to this invention, since the washing | cleaning period of a nozzle can be made longer than before, and a dirt does not adhere to the inner wall of the thread introduction hole in a core, productivity can be improved. In addition, since dirt does not adhere to the inner wall of the thread introduction hole in the core, fluctuation in the running tension of the screening and the outer layer yarns becomes smaller than before. Therefore, stable processing can be performed and the favorable bulky yarn with which the quality of a yarn was stabilized can be obtained.

In addition, a worm wheel is attached to the housing, and a worm is installed in the main body to transmit rotation to the worm wheel, thereby simplifying maintenance of the nozzle itself, and improving operability and handling. The thread hanging operation is improved. In addition, the overall structure is simplified.
