Description

The present invention relates to an injection nozzle used in a liquid flow type fabric processing apparatus for performing various treatments on a fabric, and a liquid flow type fabric processing apparatus provided with the injection nozzle.

Conventionally, a liquid flow type cloth processing device for performing various treatments such as dyeing and washing on a cloth has been known (see Patent Document 1). As shown in FIG. 13, this liquid flow type fabric processing apparatus has a processing tank 501 having an inlet portion 502 and an outlet portion 503 and capable of accommodating the processing fluid W, and an inlet portion 502 and an outlet portion of the processing tank 501. It includes a transfer pipe 504 that connects the 503 to form a circulation path through which the cloth C can circulate, and a liquid supply system 505 that supplies the processing fluid W housed in the processing tank 501 to the outlet portion 503. Here, the treatment fluid W is a liquid for treating the cloth C such as a dyeing liquid and a cleaning liquid, and is a fluid obtained by diluting components according to the treatment content of the cloth C with water or the like.

The treatment tank 501 is a long tank in the horizontal direction, and has an inlet portion 502 at one end in the longitudinal direction and an outlet portion 503 at the other end. The outlet portion 503 has a nozzle 510 for injecting a processing fluid (staining liquid or cleaning liquid) W, and a reel 511 for transferring and guiding the cloth C.

The liquid supply system 505 has a plurality of discharge units 506 connected to the lower part of the treatment tank 501 to discharge the treatment fluid W from the treatment tank 501, and the treatment is discharged from the treatment tank 501 through the plurality of discharge units 506. The fluid W is supplied to the nozzle 510 of the outlet portion 503. Each discharge unit 506 has a flow rate adjusting valve capable of adjusting the discharge amount of the processing fluid W.

Further, the liquid supply system 505 has a pump 507 that sends out the processing fluid W in the processing tank 501 toward the nozzle 510, and a flow rate adjusting valve 508 that is arranged upstream of the pump 507, and sends the processing fluid W to the nozzle 510. Can be supplied to.

In this liquid flow type cloth processing device 500, when processing the cloth C, a long cloth C is inserted into the processing tank 501 and the transfer pipe 504, and both ends thereof are connected. As a result, the cloth C becomes a loop that can circulate in the circulation path formed by the treatment tank 501 and the transfer pipe 504. At this time, the cloth C is hung on the reel 511 at the outlet portion 503 of the processing tank 501.

In this state, at the outlet portion 503 of the processing tank 501 of the liquid flow type fabric processing apparatus 500, the processing fluid W is directed toward the fabric C in which the nozzle 510 hangs down from the reel 511 while the reel 511 pulls up the fabric C in the processing fluid W. By injecting, the cloth C in the processing tank 501 is sequentially sent to the transfer pipe 504. Further, in the transfer pipe 504 of the liquid flow type cloth processing device 500, the fabric C in the transfer pipe 504 is sequentially processed by the flow of the processing fluid W (processing fluid W from the nozzle 510) flowing through the transfer pipe 504. It is sent to the inlet 502 of the tank 501. At this time, in the processing tank 501, the predetermined liquid level (liquid level position) is maintained, so that the cloth C floats in the processing fluid W in the processing tank 501 and is downstream of the processing tank 501 (reel 511). Transferred to the side). As a result, in the liquid flow type cloth processing device 500, the loop-shaped cloth C circulates in the processing tank 501 and the transfer pipe 504 (circulation path). Then, in this circulation, the cloth C passes through the processing fluid W in the treatment tank 501 while staying, so that the cloth treatment such as dyeing and washing is performed.

In the above-mentioned liquid flow type cloth processing apparatus 500, the injection pressure and the injection flow rate of the processing fluid W in the nozzle 510 are important parameters that influence the processing result of the cloth C, but the size of the injection port of the nozzle 510 during operation is large. Since the nozzle (gap) is fixed, that is, the injection pressure and the injection flow rate cannot be adjusted by the nozzle 510 itself, the adjustment is made by controlling the flow rate (output) of the pump 507 and the opening degree of the flow rate adjusting valve 508. rice field.

However, only by controlling the flow rate of the pump 507 and controlling the opening degree of the flow rate adjusting valve 508, the change range of the injection pressure and the injection flow rate of the processing fluid W in the nozzle 510 is narrow, and the liquid flow type cloth processing device 500 is in operation (during processing). ), And the processing fluid W has a problem of poor adaptability to a large change in sexuality.

In particular, in the treatment of the fabric C whose composition changes significantly during the treatment (for example, the weight loss processing treatment and the splitting treatment of the split fiber yarn), in the above-mentioned liquid flow type cloth processing apparatus 500, the injection is performed by the nozzle 510 during operation. Since it is difficult to drastically change the pressure and the amount of injection liquid, the amount of processing fluid W is increased in order to obtain stable operating conditions, the cloth circulation speed of cloth C is extremely reduced, and processing is performed for a long time. There was a problem that it took a lot of time and cost to establish the processing conditions.

Therefore, an object of the present invention is to provide an injection nozzle in which the injection pressure and the injection flow rate can be adjusted, and a liquid flow type fabric processing device provided with the nozzle.

The first region 31Si has the same inner diameter at each position in the virtual axis Va direction except for the end portion on the second region 32Si side. Further, the inner diameter of the first region 31Si is the same as the inner diameter of the inner peripheral surface 212Si of the tip portion 212 of the primary side member 2.

The second region 32Si has a shape along the outer peripheral surface 32So of the large diameter portion 32 so that the wall thickness of the large diameter portion 32 is constant except for the end portion on the side of the first region 31Si.

Further, the inner peripheral surface 3Si includes the above-mentioned secondary side facing surface 3S2 at a position (region) straddling the first region 31Si and the second region 32Si. The secondary facing surface 3S2 is a passage region of the cloth C in a space surrounded by the inner peripheral surface 3Si by passing the processing fluid W between the processing fluid W and the primary facing surface 212S1 of the tip portion 212. It is injected into Ar (specifically, a region surrounded by the first region 31Si). The secondary side facing surface 3S2 of the present embodiment is a surface parallel to the primary side facing surface 212S1 of the tip end portion 212 of the primary side member 2 in the entire circumferential direction.

The gap between the secondary facing surface 3S2 and the primary facing surface 212S1 is the injection port of the processing fluid W in the injection nozzle 1 of the present embodiment, and is the entire circumference of the virtual axis Va toward the passage region Ar of the fabric C. The processing fluid W is injected (discharged) in an oblique direction on the downstream side with respect to the virtual axis Va from the circumference. Further, the primary side member 2 and the secondary side member 3 move relative to each other in the virtual axis Va direction, and the distance between the primary side facing surface 212S1 and the secondary side facing surface 3S2 changes, so that the injection nozzle 1 is injected. The size of the mouth changes. In the injection nozzle 1 of the present embodiment, the primary side facing surface 212S1 and the secondary side facing surface 3S2 are maintained parallel to each other at each position in the circumferential direction. The interval with and changes.

The holding member 4 is fixed to the processing tank 11 (specifically, the hanging portion 117) while holding the secondary side member 3. The holding member 4 holds the secondary side member 3 so as to be relatively movable in the virtual axis Va direction with respect to the primary side member 2. The holding member 4 of the present embodiment has the secondary side member 3 so as to move relative to the virtual axis Va by rotating relative to the holding member 4 around the virtual axis Va. keeping.

Specifically, the holding member 4 is connected to a holding member main body 40 that holds the secondary side member 3, a first connecting portion 41 for connecting the holding member main body 40 to the processing tank 11, and a transfer pipe 12. It has a second connection portion 42 and.

The holding member main body 40 is a cylindrical portion that surrounds the secondary side member 3 from the outside with the virtual axis Va as the center.

Specifically, the female screw portion 401 is provided at a position corresponding to the male screw portion 312 of the secondary side member main body 31 on the inner peripheral surface of the holding member main body 40 in the direction of the virtual axis Va. The female screw portion 401 is formed by a groove extending in a spiral direction with the virtual axis Va as a spiral axis on the inner peripheral surface of the holding member main body 40. The female screw portion 401 is screwed with the male screw portion 312 of the secondary side member 3. By screwing the female screw portion 401 of the holding member main body 40 and the male screw portion 312 of the secondary side member main body 31, the secondary side member main body 31 (secondary side member 3) becomes the holding member main body 40 (holding member 4). ), The secondary member main body 31 moves back and forth (relatively moves) in the virtual axis Va direction with respect to the holding member main body 40 by rotating relative to the virtual axis Va. Along with this advancement and retreat, the secondary side member main body 31 (secondary side member 3) comes into contact with and separates from the primary side member 2 in the virtual axis Va direction (relative movement). In the injection nozzle 1 of the present embodiment, the secondary side member 3 moves by 8 mm in the virtual axis Va direction by rotating once around the virtual axis Va. The movement of the secondary side member 3 in the virtual axis Va direction with respect to the rotation angle around the virtual axis Va is the spiral ridge of the male threaded portion of the secondary side member and the spiral groove of the female threaded portion of the holding member. It is defined by the pitch in the virtual axis Va direction of.

The first connecting portion 41 is a flange-shaped portion of the holding member main body 40 that extends radially outward from the upstream end portion in the traveling direction of the fabric C. Further, the second connecting portion 42 is a flange-shaped portion of the holding member main body 40 that extends radially outward from the downstream end portion in the traveling direction of the fabric C.

The drive unit 5 of the present embodiment is attached to the holding member 4. Specifically, the drive unit 5 includes a motor 51 and a worm shaft 52 to which the rotational driving force of the motor 51 is transmitted.

The motor 51 of this embodiment is a stepping motor. Further, the worm shaft 52 meshes with the worm wheel portion 311 of the secondary side member 3 held by the holding member 4, and forms a worm gear together with the worm wheel portion 311 of the secondary side member 3. The worm shaft 52 transmits the rotational driving force from the motor 51 to the secondary side member 3 through the worm wheel portion 311. By transmitting this rotational driving force, the secondary side member 3 rotates relative to the holding member 4 with the virtual axis Va as the center of rotation. Due to this relative rotation, the male screw portion 312 of the secondary side member 3 and the female screw portion 401 of the holding member 4 are screwed together, so that the secondary side member 3 is in the virtual axis Va direction with respect to the holding member 4. Advance and retreat. The worm shaft 52 of the present embodiment extends in the horizontal direction and meshes with the worm wheel portion 311 of the secondary side member 3.

The control unit 6 can control the size of the injection port in the injection nozzle 1 (the distance between the primary side facing surface 212S1 and the secondary side facing surface 3S2) and the liquid supply system 13. The control unit 6 of the present embodiment controls the size of the injection port of the injection nozzle 1 through the drive unit 5.

Specifically, the control unit 6 controls the motor 51 of the drive unit 5 to connect the primary side facing surface 212S1 of the tip portion 212 of the primary side member 2 and the secondary side facing surface 3S2 of the secondary side member 3. Adjust (control) the interval. Further, the control unit 6 adjusts (controls) the flow rate of the processing fluid W injected from the injection nozzle 1 by controlling the pump P of the liquid supply system 13 and the opening degree of the flow rate adjusting valve 1351a. Further, the control unit 6 adjusts (controls) the flow rate of the processing fluid W flowing through the discharge pipes 1311, 1321, 1331 by controlling the opening degrees of the electric valves 1312, 1322, and 1332 of the liquid supply system 13, respectively. ), Adjusting the flow rate of the processing fluid W discharged from the connection positions of the discharge pipes 1311, 1321, 1331 in the processing tank 11. The control unit 6 of the present embodiment can independently control each of the motor 51, the pump P, the flow rate adjusting valve 1351a, and the electric valves 1312, 1322, and 1332. The control unit 6 of the present embodiment also controls the temperature control unit 1352. That is, the control unit 6 also controls the temperature of the processing fluid W circulating in the circulation path by controlling the temperature control unit 1352.

In the above-mentioned woven fabric processing apparatus 10, the woven fabric C is processed (in the example of the present embodiment, the weight of the polyester woven fabric C is reduced) as follows.

In the processing tank 11, the long cloth C is carried into the processing tank 11 from the first end portion 111 in the open state in which the opening / closing door 116A is opened. The carried-in cloth C is inserted into the transfer pipe 12, and both ends thereof are connected to form a loop that can circulate through the circulation path formed by the processing tank 11 and the transfer pipe 12. At this time, the cloth C is wound around the reel 116B of the first end portion 111.

When the cloth C is arranged so as to be able to circulate in the circulation path, the opening / closing door 116A is closed and the operation (cloth processing) of the cloth processing device 10 is started. Specifically, it is as follows.

By driving the pump P, the processing fluid W in the processing tank 11 is discharged from each of the discharge units 131, 132, 133, and is supplied from the supply pipe 1351 into the hanging portion 117 of the processing tank 11 through the connection unit 1171. .. The processing fluid W at this time is water at room temperature.

The processing fluid W supplied into the hanging portion 117 is between the primary side member 2 and the secondary side member 3 of the injection nozzle 1, more specifically, the tip portion 212 of the cylindrical portion 21 and the secondary side member 3. It flows into the injection nozzle 1 from between the large diameter portion 32 and the large diameter portion 32 of the above. At this time, the processing fluid W passes between the support portions 2132 of the guide portion 213 and flows in between the tip portion 212 of the primary side member 2 and the large diameter portion 32 of the secondary side member 3, so that the virtual shaft Between the tip portion 212 of the primary side member 2 and the large diameter portion 32 of the secondary side member 3 without vortexing around Va, that is, in a state where the velocity component in the circumferential direction around the virtual axis Va is suppressed. Inflow to.

In this way, the processing fluid W that has flowed in between the tip portion 212 of the primary side member 2 and the large diameter portion 32 of the secondary side member 3 in a state where the velocity component in the circumferential direction around the virtual axis Va is suppressed is Diagonal direction (including the velocity component in the traveling direction of the fabric C) from between the primary side facing surface 212S1 and the secondary side facing surface 3S2 (injection port) toward the center (virtual axis Va) of the hollow portions 210 and 310. Direction). At this time, the processing fluid W is injected onto the cloth C from the entire circumference around the virtual axis Va. The cloth C begins to circulate in the circulation path due to the force in the traveling direction applied to the cloth C by this injection, the flow of the processing fluid W in the transfer pipe 12 generated by the injection, and the rotational drive of the reel 116B.

Further, along with the drive of the pump P, the control unit 6 determines the size of the injection port of the injection nozzle 1 (primary side facing surface 212S1 and secondary) so that the fabric C runs stably based on the detection results by various sensors and the like. The distance from the side facing surface 3S2) is adjusted. At this time, in addition to adjusting the size of the injection port of the injection nozzle 1, the control unit 6 adjusts the flow rate of the pump P, the opening degree of the flow rate adjusting valve 1351a, and each discharge unit 131 so that the cloth C runs stably. , 132, 133, and at least one of the opening degrees of the electric valves 1312, 1322, and 1332 may be adjusted together.

In adjusting the size of the injection port, since the worm shaft 52 of the drive unit 5 and the worm wheel unit 311 of the secondary member main body 31 form a worm gear, the drive unit 5 of the injection nozzle 1 is a worm shaft. By rotationally driving the 52, the secondary side member main body 31 is rotated around the virtual axis Va with respect to the holding member 4. Since the secondary side member 3 and the holding member 4 are screwed by the spiral male screw portion 312 and the female screw portion 401 having the virtual shaft Va as the spiral shaft, the rotation of the secondary side member main body 31 causes the secondary side member 3 and the holding member 4 to be screwed together. The secondary side member 3 moves back and forth (moves) in the virtual axis Va direction with respect to the holding member 4 and the primary side member 2. At this time, the large diameter portion 32 of the secondary side member main body 31 (inner peripheral surface 322Si of the short tubular portion 322: see FIG. 6) is the guide portion 213 of the tubular portion 21 of the primary side member 2 (outer peripheral surface of the annular portion 2131). 2131So: see FIG. 5) so that the center of the large diameter portion 32 of the secondary side member 3 moves relative to the primary side member 2 in a state where it coincides with the virtual axis Va. 3 is guided.

When the circulation of the cloth C in the circulation path is stabilized as described above, NaOH is added to the circulating processing fluid W.

Next, the control unit 6 heats the processing fluid (water to which NaOH is added) W by the temperature control unit 1352 to raise the temperature of the processing fluid W. At this time, the control unit 6 raises the temperature of the processing fluid W from 60 ° C. to 100 ° C. over 10 minutes by the temperature control unit 1352, and when the temperature of the processing fluid W rises to 100 ° C., then 20 The temperature of the processing fluid W is raised from 100 ° C. to 130 ° C. over a minute. When the temperature of the processing fluid W rises to 130 ° C., the control unit 6 maintains this temperature for 60 minutes and then lowers the temperature of the processing fluid W from 130 ° C. to 80 ° C. over 10 minutes.

After that, the cloth C is washed by circulating the cloth C in a circulation path in a state where the treatment fluid (water to which NaOH is added) is replaced with a new treatment fluid (water at room temperature) W. This cleaning step is performed a plurality of times, and the processing fluid (water after cleaning) W is replaced with a new processing fluid (water) W for each cleaning step.

After a plurality of cleaning steps are completed, the processing fluid (water after cleaning) W is replaced with a new processing fluid (water at room temperature) W, and then a neutralizing agent such as acetic acid is added to the processing fluid W for control. Unit 6 raises the temperature of the processing fluid W to 60 ° C. by the temperature control unit 1352. When the temperature of the processing fluid W rises to 60 ° C., the control unit 6 maintains this temperature for 5 minutes to perform the neutralization treatment.

When this neutralization treatment is completed, the washing step is performed again, and the fabric treatment (weight reduction processing) in the fabric processing device 10 is completed.

Changes in the properties of the cloth C and the properties of the processing fluid W during the processing of the fabric C by the fabric processing apparatus 10 as described above (in the example of the present embodiment, the weight loss processing) occur at various points depending on the processing content and the like. ..

For example, when the cloth C is a synthetic fiber, the property changes due to temperature changes (normal temperature and 100 ° C. or higher). Specifically, the dough becomes soft at high temperatures, and the dough becomes harder at room temperature than at high temperatures. Further, in the process of reducing the volume of the cloth C by thinning the fibers (reducing the weight of the cloth C) such as the above-mentioned weight reduction process of polyester, the properties change (the fibers become thin and the cloth becomes soft) as the process progresses. appear. The same applies to split fiber processing.

In the cloth processing apparatus 10 of the present embodiment, every time the above-mentioned property change of the cloth C or the property change of the processing fluid W occurs during the processing of the cloth C, the control unit 6 processes the cloth at a high temperature and high pressure. By controlling the size of the injection port of the injection nozzle 1 inside the device 10 and adjusting the injection flow rate and the injection pressure of the processing fluid W injected from the injection nozzle 1 toward the cloth C, the cloth C is stabilized. Keep running.

Further, the control unit 6 controls each of the discharge amount of the pump P and the opening degree of the flow rate adjusting valve 1351a in addition to the size of the injection port of the injection nozzle 1 in order to maintain the stable running of the fabric C. Therefore, the injection flow rate and the injection pressure of the processing fluid W injected from the injection port of the injection nozzle 1 may be adjusted. At this time, the control unit 6 can independently adjust (control) the size of the injection port of the injection nozzle 1, the flow rate of the pump P, and the opening degree of the flow rate adjusting valve 1351a. That is, the control unit 6 can adjust only the injection flow rate while keeping the injection pressure in the injection nozzle 1 at a predetermined pressure, and can also adjust only the injection pressure while keeping the injection flow rate at a predetermined flow rate. Is.

The control unit 6 adjusts the size of the injection port of the injection nozzle 1, the discharge amount of the pump P, and the opening degree of the flow rate adjusting valve 1351a, as well as the electric valves 1312 and 1322 of the discharge units 131, 132 and 133. The stable running of the cloth C may be maintained by adjusting (controlling) the opening degree of the 1332 and the like.

Further, regardless of whether the fabric C is a synthetic fiber or a natural fiber, a change in properties occurs in the following cases. When the dyeing step / function-imparting step of the cloth C is performed in the cloth processing apparatus 10, after these steps, the cloth C is washed (after replacing the treatment fluid W with fresh water or while replacing with fresh water). (Circulation) step is performed. In this step, the chemicals impregnated in the cloth C and the chemicals in the treatment fluid W are removed, so that the slip of the cloth C and the foamability of the treatment fluid W are improved. Property changes such as reduction occur. Even in these cases, in the cloth processing device 10, the control unit 6 controls the size of the injection port of the injection nozzle 1 to maintain the stable running of the cloth C.

According to the injection nozzle 1 of the fabric processing apparatus 10 described above, the primary side member 2 through which the processing fluid W injected into the passage region Ar of the fabric C in the space surrounded by the inner peripheral surface 3Si of the secondary side member 3 passes. The distance between the tip end portion 212 of the above and the secondary side facing surface 3S2 of the secondary side member 3 can be changed. As a result, the injection flow rate and the injection pressure of the processing fluid W can be adjusted by the injection nozzle 1 itself. As a result, the size of the injection port of the injection nozzle 1 (the distance between the primary side facing surface 212S1 and the secondary side facing surface 3S2) cannot be changed, and only the flow rate of the pump P and the opening degree of the flow rate adjusting valve 1351a can be adjusted. The adjustment range between the injection flow rate and the injection pressure of the processing fluid W in the injection nozzle 1 is larger than that of the configuration to be performed.

Therefore, the processing fluid W is sprayed onto the cloth C passing through the regions 210 and 310 surrounded by the inner peripheral surfaces 3Si of the secondary side member 3 so as to have a velocity component in the passing direction of the cloth C. That is, from the gap between the primary side facing surface 212S1 and the secondary side facing surface 3S2 constituting the injection port, the processing fluid W has a velocity component in the traveling direction of the fabric C in the circumferential direction of the hollow portions 210 and 310. It is sprayed diagonally from the entire area (diagonally downward in the example of the above embodiment). As a result, the force in the traveling direction of the cloth C is applied to the cloth C passing through the regions 210 and 310 from the processing fluid W.

Further, in the injection nozzle 1 of the present embodiment, the secondary side member 3 moves relative to the primary side member 2 in the traveling direction (passing direction) of the fabric C, so that the tip portions 212 and 2 of the primary side member 2 are moved. The distance between the secondary side member 3 and the secondary side facing surface 3S2 is changed. In this way, by making the secondary side member 3 relatively movable with respect to the primary side member 2 arranged on the upstream side, it becomes easy to secure a movable distance. It becomes easy to secure the change width of the distance from the next facing surface 3S2.

A female screw portion 401 provided at a portion surrounding the member 3 is screwed. Then, the secondary side member 3 and the holding member 4 rotate relative to each other around the virtual axis Va, so that the secondary side member 3 moves relative to the primary side member 2 in the virtual axis Va direction. In this way, the injection pressure of the processing fluid W is formed by screwing the secondary side member 3 and the holding member 4 so as to rotate relative to each other with the virtual axis Va extending in the relative moving direction as the center of rotation. It becomes easy to adjust (change) the distance between the tip portion 212 (primary side facing surface 212S1) and the secondary side facing surface 3S2 in a high state.

Further, the injection nozzle 1 of the present embodiment includes a drive unit 5 that drives the secondary side member 3 to rotate the secondary side member 3 and the holding member 4 relative to each other. Therefore, it becomes easier to adjust (change) the distance between the tip portion 212 and the secondary side facing surface 3S2 when the injection pressure of the processing fluid W is high or the like.

Can be automatically controlled. Moreover, in addition to the flow rate of the pump P, the distance between the tip portion 212 of the injection nozzle 1 and the secondary side facing surface 3S2 can be changed, so that the injection pressure and the injection flow rate having a large adjustment range can be automatically controlled.

The opening is adjusted respectively. In this way, the control unit 6 adjusts (controls) the distance between the tip portion 212 and the secondary side facing surface 3S2 and the opening degree of the flow rate adjusting valve 1351a, respectively, so that the injection pressure of the processing fluid W at the injection nozzle 1 and the injection pressure of the processing fluid W Automatic control of injection flow rate becomes possible. Moreover, in addition to the opening degree of the flow rate adjusting valve 1351a, the distance (the size of the injection port) between the tip portion 212 and the secondary side facing surface 3S2 in the injection nozzle 1 can be changed, so that the injection pressure and the injection flow rate having a large adjustment range can be changed. Can be automatically controlled.
