DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jetting device provided at the end of a transfer pipe for feeding a cloth in a liquid dyeing machine.

[0002]

2. Description of the Related Art A liquid dyeing machine comprises a dyeing tank, a transfer pipe, and a heat exchanger. Fabrics move at high speed in a transfer pipe by a jet liquid flow while contacting a processing liquid, and flow into the dyeing tank. In the dyeing tank, the inflowing fabric is regularly arranged and moved, pulled up by a drive reel, and moved again in the transfer pipe at a high speed by a jet liquid flow. In this way, the fabric is dyed while repeatedly circulating through the transfer tube and the dyeing tank, and the fabric is also subjected to a relaxing untwisting process as necessary.

As described above, the cloth circulates through the transfer tube and the dyeing tank. For this purpose, the nozzle provided in the injection device must jet the processing liquid in the axial direction of the transfer tube.
In addition, although the force for flushing the fabric increases as the amount of the treatment liquid sprayed increases, it is necessary for the ejecting device to relax the fabric, instead of performing the function of simply flushing the fabric at high speed. That is, in order to rub and relax the fabric, it is necessary to apply a force from the outside to the center.

[0004] The nozzles provided in the conventional injection device are roughly classified into a span nozzle and a filament nozzle. The span nozzle is a nozzle that changes the injection cross-sectional area by combining a frusto-conical skimmer cone and a mecha cone, and has a skimmer cone of about 2 mm in one to three stages. The spray angle with respect to the cloth is generally 10 °.
This spun nozzle is a nozzle intended for a fabric made using spun yarn, and can be conveyed at a relatively large flow rate at a low nozzle pressure, and does not damage the fabric.

[0005] One filament nozzle is constructed by combining a nozzle pipe and an outer ring (nozzle boss), and a processing liquid can be jetted from a gap between the nozzle pipe and the outer ring. This gap can be adjusted by a ring or the like. I have. This nozzle is a nozzle for a fabric made using a filament system, and conveys the fabric at a small flow rate and a high nozzle pressure. The spray angle is 30 ° to 40 °, and the contact angle with the fabric is large.

As described above, the spun nozzle is superior in the ability to send the fabric in the axial direction of the transfer pipe due to the large ejection amount of the processing liquid and the small ejection angle. However, the span nozzle presses the fabric from the outside. The power to loosen is small. On the other hand, the filament nozzle has a large spray angle, so that a pressing force from the outside to the center is generated and can be loosened.However, the amount of the processing liquid jetted is small, and there is no movement of wrinkles in the transfer pipe, and the fabric is twisted. Many wrinkles, twists, etc. occur in the product due to the above factors.

[0007]

As described above, the jetting device provided at the end of the transfer pipe of the liquid jet dyeing machine uses either the above-mentioned span nozzle or filament nozzle. There is a problem as described above. The problem to be solved by the present invention is this problem, in which the fabric can be washed away at a high speed, and the fabric is rubbed by applying a pressing force from the outside toward the center,
In addition, the present invention provides a jet apparatus of a liquid jet dyeing machine that can suppress generation of wrinkles and twists, and can dye and relax for various uses and various kinds.

[0008]

The jetting device in the jet dyeing machine according to the present invention arranges a filament type nozzle and a span type nozzle in a pair, and the characteristics of each nozzle are obtained by using both nozzles in combination. Pull it out to make an injection device suitable for fabric. In other words, the processing liquid is jetted from both nozzles to flush the fabric at a high speed, and the pressing force from the outside toward the center is applied to function as a kneading agent. By controlling, the carrying capacity and the kneading and loosening ability suitable for the fabric are adjusted. The ejection amount of the processing liquid can be adjusted by attaching a ring having an appropriate thickness and appropriately determining the size of the gap between the nozzles.

In this case, the filament nozzle of the injection device rectifies the flow of the processing liquid flowing from one side of the nozzle provided at the tip of the transfer pipe, and sprays the flow toward the central axis of the transfer pipe. If the jet direction of the processing liquid shifts from the center of the transfer pipe, a vortex will be generated there, causing twisting or twisting of the fabric. However, the filament nozzle of the present invention forms a slight gap diagonally. In addition, a stabilizing groove is provided in some places in the direction of the central axis of the transfer pipe. Therefore, the processing liquid is stably jetted toward the center of the transfer pipe, and twisting and twisting of the cloth are prevented. The treatment liquid jetted from the filament nozzle has a large jetting angle and acts to press the fabric from the outside toward the center. As a result, the fabric is rubbed and loosened.

[0010] One of the span type nozzles also has a nozzle base in which the tip of the nozzle pipe is inclined and an appropriate gap is interposed between the nozzle pipe and the inclined surface. The jetting direction of the processing liquid is determined according to the angle of the inclined surface provided in the nozzle table in abutment with the tip of the pipe, so that it is possible to perform the function of merely flushing the fabric or to sometimes apply the pressing force in the kneading direction. . In the injection device of the present invention, the arrangement order of the filament nozzle and the span nozzle is not limited. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0011]

FIG. 1 shows an embodiment of a jet dyeing machine according to the present invention. In the figure, 1 is a cloth, 2 is a transfer tube, 3 is a dyeing tank, 4 is a jetting device, and 5 is a pulling reel of the cloth. As shown in the drawing, the liquid jet dyeing machine dyes the cloth 1 by circulating the cloth 1 through the transfer pipe 2 and the dyeing tank 3. In addition to the dyeing of the fabric, the jet dyeing machine functions to remove the wax and the sizing agent adhering to the fabric, and to further rub and loosen to perform a relaxing and untwisting treatment.

The cloth 1 is pushed down the transfer pipe 2 together with the processing liquid, stays in the dyeing tank 3, is pulled up again from the dyeing tank 3, and is pulled up by the processing liquid 6 jetted from the reel 5 and the jetting device 4. Is propelled and swept away.
The processing solution 6 that has entered the dyeing tank 3 flows out of outlets 7 provided below, passes through a heat exchanger 8, and is jetted from an injection device 4. The heat exchanger 8 is a device for keeping the temperature of the processing liquid 6 at a predetermined temperature. 9 denotes a pump, which injects the processing liquid from the injection device 4 by the pump 9.

By the way, these are the basic structures of the jet dyeing machine, but the present invention is characterized by the jetting device 4 provided at the tip of the transfer pipe 2 and below the pulling reel 5. FIG. 2 shows a cross section of the injection device 4 and is an embodiment of the present invention. The processing liquid 6 enters the injection device 4 from an inflow pipe 10 led from the heat exchanger 8, flows in the direction of the arrow, and is injected from the nozzle. By the way, in the injection device of the present invention, the filament type nozzle 11 and the span type nozzle 12 are mounted in pairs.

The filament nozzle 11 includes a nozzle pipe 13, a collar 14, and a flow regulating member 15. The collar 14 is fixed to the outer periphery of the end of the nozzle pipe 13,
The protrusion formed on the fixture 16 is fitted and positioned in the recess formed on the end face 4. And the collar 1
An outer ring 17 is attached so as to cover the outer periphery of the rectifying member 15 and the rectifying member 15, and inlets 18, 18... Further, a gap setting ring 29 is inserted between the collar 14 and the outer ring 17 so that an appropriate amount of the processing liquid can be jetted by a gap formed between the nozzle pipe 13 and the inclined portion 21.

One of the span type nozzles 12 is composed of a nozzle pipe 19 having an inclined portion 21 and a rectifying member 20 fixed to the outer periphery of the tip, and the end of the inclined portion 21 is positioned by being locked to the end of the outer ring 17. Pipe 19 and rectifying member 20
Outer ring 22 is attached so as to cover. The outer ring 22 is fitted in the center hole of the fixed base 23 of the injection device 4 and its tip is positioned. The tip of the nozzle pipe 19 is also inclined, and a nozzle table 25 having a slope 24 facing the inclined face is fitted to the tip. As with the filament nozzle 11, a gap setting ring 30 is inserted between the end of the inclined portion 21 and the outer ring 22, and an appropriate amount of the processing liquid is jetted from a gap formed between the nozzle table 25 and the nozzle pipe 19.

By the way, the processing liquid flowing from the inflow pipe 10 is supplied to the inlets 18 formed in the outer rings 17 and 22 at various places.
, And passes through the flow regulating members 15 and 20 and is ejected from the tip of the nozzle. Here, the filament nozzle 11
In this case, the tip of the nozzle pipe 13 is inclined, and as shown in FIG. 3, stable grooves 27 are formed on the inclined surface 26 so as to form an appropriate gap 2 between the nozzle pipe 19 and the inclined portion 21.
8 is left. Since the gap 28 is formed continuously over the entire circumference, the processing liquid passing through the gap 28 is jetted along the inclined portion 21 and the inclined surface 26.

A plurality of stabilizing grooves 27 are provided at appropriate locations on the inclined surface 26, and the processing liquid passing through the stabilizing grooves 27
Inject at an intermediate angle between 1 and the bottom of the stable groove. Further, since the processing liquid jet from the stabilizing grooves 27, 27,... Has a lower resistance than that when passing through the inclined surface 26, the flow velocity becomes faster and at the same time becomes an acute angle with respect to the cloth, so that the driving force for pushing the cloth is obtained. Can be

As described above, the stable grooves 2 are formed on the inclined surface 26 in some places.
Are formed, all the spraying treatment liquid is sprayed toward the central axis of the transfer pipe 2 while being restrained by the flow of the stabilizing grooves 27. Then, the processing liquid that has passed through the rectifying member 15 is subjected to the inclined portion 21 and the tip inclined surface 26
Is sprayed to massage and loosen the fabric 1 to relax. Here, if the thickness of the ring 29 is changed to adjust the ejection amount of the processing liquid, the nozzle pipe 13 moves, and as a result, the position of the nozzle pipe 19 from the inclined portion 21 changes, and the gap 28 increases or decreases. I do.

On the other hand, the amount of the processing liquid ejected from the span system nozzle 12 is determined by the gap between the inclined surface formed at the tip of the nozzle pipe 19 and the inclined surface of the nozzle table 25. The nozzle pipe 19 moves with a ring 30 of a required thickness interposed between the nozzle pipe 19 and the nozzle pipe 22. By doing so, it is possible to control the force by which an appropriate amount of the processing liquid is jetted and the cloth is washed away.

As described above, the adjustment of the clearance between the nozzles is performed by the ring 2.
This is performed in steps 9 and 30, and can be set in the range of 0 mm to several mm. Further, in the present invention, the inclination angle of the nozzle table can be arbitrarily changed. For example, FIG. 4 shows a case where the nozzle table 25 is replaced and the inclination angle of the slope is increased. Therefore, in this nozzle base, the speed of the processing liquid ejected from the outside toward the center increases, and a force for kneading the cloth 1 is also generated.

FIG. 5 shows a case in which another nozzle table 25 is attached. The inclination of the slope 24 becomes zero, and as a result, the processing liquid is ejected in the axial direction of the transfer pipe to force the cloth to flow away. Become. However, there is almost no pressing force for kneading and loosening the cloth. As described above, the injection device according to the present invention has the filament type nozzle and the span type nozzle mounted in pairs, and the following effects can be obtained.

[0022]

The injection device according to the present invention is provided with a filament nozzle and a span nozzle in pairs. Accordingly, a pressing force for kneading and loosening the fabric is exerted by the filament system nozzle, and the fabric is simultaneously pushed into the transfer pipe by the treatment liquid jetted from the span system nozzle, thereby improving the kneading effect and the moving speed of the fabric. Further, the stabilizing groove formed in the filament type nozzle provides two types of jets at different angles, thereby preventing twisting of the fabric and transporting the fabric to the dyeing tank at a stable speed. And by controlling the amount of the processing liquid jetted from the filament nozzle and the span nozzle, the conveying force and the kneading force can be realized in the optimum jetting state in accordance with the properties of the fabric. It is possible to carry out multi-product / multi-purpose fabric treatment while suppressing occurrence.
