However, if the rotating drum is rotated at a low speed, the stirrability of the treatment liquid or the object to be treated in the treatment liquid is likely to be reduced, and there is a concern that the stagnation operability imparted to the object to be treated may be deteriorated. The decrease of
Therefore, instead of rotating the rotating drum at a low speed, increasing the amount of processing liquid (with a high bath ratio) eliminates deterioration in processability such as dyeing due to the reduction in stagnation operability applied to the object to be processed. It is possible to do. However, when the amount of the processing liquid is increased, the running cost, such as requiring more energy for increasing the temperature of the processing liquid, is increased.

Therefore, in view of the above-described conventional problems, an object of the present invention is to provide a staining apparatus and a staining method capable of improving the dyeability of an object to be processed while suppressing an increase in running cost.

The present invention is a rotary drum which is horizontally put the dough-like object to be processed is rotated or swung in the horizontal axis, by immersing the object to be processed stained該被treated in the dyeing liquid in the rotary drum A dyeing device for jetting fluid from the lower side toward the dyeing liquid in the rotating drum when the rotating drum rotates or swings, and is ejected from the jetting port It is characterized in that the object to be treated is soaked in the dyeing liquid by the pressure of the fluid.

According to the above configuration, the processing liquid is put in the rotating drum, and the dyeing liquid in the rotating drum is efficiently stirred by ejecting the fluid from the ejection port when the rotating drum rotates or swings. Even in a state where the bath ratio, which is the ratio between the amount of the object to be processed and the amount of the dyeing liquid, is lowered (low bath ratio), the dyeing liquid easily contacts the object to be processed uniformly.
Object to be treated, synthetic fibers, synthetic leather, cotton, rayon, if a dough-like material blend be rinsed containing cellulosic fibers and cellulosic fibers (thin-shaped body), dyeing processes it, by the fluid By stirring the dyeing liquid, it becomes easy to create a state in which the dyeing liquid uniformly contacts the entire surface including the wrinkle portion of the dough-like material, and the fluid is ejected from the spout and is immersed in the dyeing liquid. The processed material itself is agitated in the dyeing liquid, and the position of wrinkles generated in the processed material is highly varied, so that the entire processed material can be processed. It becomes uniform.
The fluid may be a dyeing liquid itself, a gas such as air, or a vapor depending on the dyeing process of the object to be processed.
In addition, as a rotating drum, a type in which the interior is partitioned into a plurality of chambers by a partition wall, a locking for locking an object to be processed when the rotating drum rotates or swings on the inner peripheral surface of the rotating drum. Includes types with ribs. Further, the rotating drum is not limited to a cylindrical shape, but includes a rectangular tube shape.

In the dyeing apparatus of the present invention, the rotating drum is housed in the tank body, a hole through which the dyeing liquid can pass is formed on the peripheral wall surface of the rotating drum, and the ejection port has its fluid ejection end on the horizontal axis of the rotating drum. It arrange | positions so that a fluid may be ejected toward the center of a rotating drum from the outer side of the surrounding wall surface of a rotating drum in the position corresponding to the hole in the axial direction.

  According to the above configuration, the fluid is ejected from the ejection end of the ejection port portion from the hole portion of the peripheral wall surface of the rotating drum rotating or swinging around the horizontal axis in the tank body into the rotating drum.

The dyeing apparatus of the present invention is characterized in that a plurality of hole portions are formed in the same circumferential direction of the peripheral wall surface of the rotating drum so as to be provided with a hole group on the peripheral wall surface of the rotating drum.

According to the above configuration, when the hole group is positioned so as to correspond to the ejection end of the ejection port portion as the rotation drum rotates or swings around the horizontal axis, the fluid is ejected into the rotation drum, Since the fluid is intermittently ejected into the rotating drum so that the fluid is not directly ejected into the rotating drum when the part group moves away from the position corresponding to the ejection end of the ejection port portion. Even if the bath ratio, which is the ratio between the amount of the object to be processed and the amount of the dyeing liquid, is lowered, the liquid for dyeing in the rotating drum generates periodic flow (pulsation), and the stagnation of the object to be processed That is, the degree of uniformly holding the entire object to be processed is good.

In the dyeing device of the present invention, a plurality of hole groups are provided apart from each other in the axial direction of the horizontal axis of the rotary drum, and the jet outlets are respectively provided at positions corresponding to the hole groups in the axial direction of the horizontal axis. It is characterized by that.

According to the above configuration, pulsation of the dyeing liquid is generated at a plurality of locations in the rotating drum as the rotating drum rotates or swings around the horizontal axis, so that the stagnation of the workpiece is further improved.

The dyeing device of the present invention is characterized in that the fluid ejection end of the ejection port portion is disposed within a range of 80 ° from the lower side in the vertical direction of the center of the rotating drum to the circumferential direction of the rotating drum.

When ejecting fluid from below the staining solution, the energy of the fluid more liquid level of the dyeing liquid is low is ejected is not easily diffused into the spout portion. Therefore, by setting the fluid ejection end of the ejection port at the above position, the object to be treated can be sufficiently stirred in the staining liquid and the staining liquid in a state where a low bath ratio is ensured.
Therefore, the fluid needs to have discharge force capable of stirring thoroughly the dyeing liquid can grant moving force to the object to be processed in the staining solution (discharge energy). This discharge force is preferably such that at least the fluid reaches the level of the dyeing liquid according to the amount of the dyeing liquid in the rotating drum.
In the case where the workpiece is held so as to be pushed up from below, the fluid ejection end of the ejection port portion is arranged within a range of 80 ° from the vertical lower side of the center of the rotating drum to the circumferential direction of the rotating drum. to eject fluid in the rotary drum, stirring of the staining solution on which the low bath ratio was found to be excellent in stirring of the object to be treated in a dyeing solution.

In the method for dyeing a dough-like object to be processed according to the present invention, the object to be processed is placed in a rotating drum placed horizontally, and the rotating drum is rotated or oscillated around the horizontal axis while the object to be processed is immersed in the dyeing solution. It is characterized in that, during the operation, a fluid is ejected from the lower side toward the dyeing liquid in the rotating drum, and the object to be treated is swollen in the dyeing liquid by the pressure of the fluid.

According to the above method, dyeing liquid in the rotary drum by the ejection of the fluid is agitated, and because the fluid is given the operation object to be treated itself against the object to be processed, even dyeing liquid small amount to be The dyeing of the processed object becomes uniform, and the dyeability of the object to be processed can be improved.

According to the dyeing apparatus of the present invention, by ejecting the fluid from the spout portion during rotation or oscillation of the rotary drum, because it is possible to stir the dyeing liquid in the rotary drum efficiently, the amount of the object to be treated The bathing ratio, which is the ratio of the dyeing solution to the amount of the dyeing solution, is lowered (low bathing ratio), that is, the running solution is kept from rising, and the dyeing solution can be brought into uniform contact with the object to be treated. The object to be treated is a fabric-like material (thin body) such as synthetic fiber, synthetic leather, cotton, rayon, cellulose fiber and cellulose fiber, and when this is dyed and processed, homogeneously easily create a state in which the staining solution is in contact with the whole, including the wrinkle portion of the dough-like material by staining solution by the fluid is agitated, this dyeing liquid fluid is ejected from the ejection opening By being applied to the dough-like material soaked in In dyeing liquor by treatment object itself is agitated, rich in position change of wrinkles portion for generating the dough-like material, can be carried out uniformly dyeing of the entire object to be processed, the object to be treated it is possible to improve the dyeing properties.

According to the dyeing process of the present invention, the stirring dyeing liquid in the rotary drum by the ejection of the fluid, and because the fluid is given the operation object to be treated itself against the object to be treated, there in staining solution a small amount However, the processing of the object to be processed becomes uniform, and the dyeability of the object to be processed can be improved.

  As described above, the dyeing tank 5 includes the rotating drum 15 that is smaller than the diameter of the dyeing tank 5 by a predetermined diameter, and therefore the inner peripheral surface of the peripheral wall 21 of the dyeing tank 5 and the rotating drum 15 rotating drum 15.

  The processing apparatus 1 in this embodiment has a fluid ejection device 28 that agitates the treatment liquid 24 in the rotary drum 15 and ejects the fluid 27 so as to apply a moving force (stirring force) to the workpiece 26. In this case, the fluid 27 is a dyeing liquid as the processing liquid 24. In short, the treatment liquid 24 is circulated as the fluid 27.

The fluid ejection device 28 includes the ejection nozzles 30 </ b> A and 30 </ b> B serving as ejection ports and a circulation path 31 for the fluid 27.
The nozzle body 34 of the ejection nozzles 30 </ b> A and 30 </ b> B is inserted and fixed to the peripheral wall 21 of the dyeing tank 5. The tip portions of the ejection nozzles 30A and 30B are formed in a truncated cone shape and inserted into the gap B. The ejection nozzles 30 </ b> A and 30 </ b> B eject fluid 27 at a predetermined speed and flow rate from the fluid ejection end 32 at the tip thereof toward the center of rotation of the rotary drum 15 from below with respect to the processing liquid 24 in the rotary drum 15. Therefore, the ejection nozzles 30 </ b> A and 30 </ b> B have fluid ejection ends 32 in the same cross section with a predetermined hole group 25 in the rotary drum 15 (in a cross section perpendicular to the horizontal axis 16). It is provided as follows. The fluid ejection end 32 faces the outer peripheral surface of the peripheral wall 22 of the rotary drum 15 via a slight gap.

(Symbol omitted) is connected.
The circulation pipe 38 and the ejection nozzles 30A, 30B are connected via a joint 40 that ensures sealing performance.
In FIG. 3, reference numeral 45 indicates a drain port for the treatment liquid 24.

First, an outline of the method for dyeing the workpiece 26 in the processing apparatus 1 having the above-described configuration will be described.
The fluid 27 is ejected from below into the treatment liquid 24 in the rotary drum 15 to agitate the treatment liquid 24 (fluid 27), and the workpiece 26 itself is moved (stirring) by the ejection output (ejection energy) of the fluid 27. In addition, the workpiece 26 is dropped in the rotary drum 15 while the rotary drum 15 is being rotated, so that a rotational kneading operation is imparted to the workpiece 26 itself. As a result, the portion to be processed 26 can be evenly dyed.

More specifically, the door member 8 is opened around the hinge member, the workpiece 26 is introduced into the rotary drum 15 from the first inlet / outlet member 7 and the second inlet / outlet member 17, and the door member 8 is moved. close up. When information about the object to be processed 26 such as the type and amount of the object to be processed 26 is input by operating the operation panel 4 and the apparatus is driven, the object to be processed 26 is immersed according to the information on the object to be processed 26. A certain amount of the processing liquid 24 is supplied into the dyeing tank 5 from the supply port 29 a of the supply line structure 29.
The processing liquid 24 is directly supplied into the dyeing tank 5, but a number of punching holes 23 are formed in the peripheral wall 22 of the rotary drum 15, so that the processing liquid 24 supplied into the dyeing tank 5 is punched. Through the hole 23, it also enters the rotary drum 15, the treatment liquid 24 in the dyeing tank 5 and the treatment liquid 24 in the rotary drum 15 are at the same level, and the object 26 is immersed in the treatment liquid 24.

  Subsequently, the driving motor 20 is driven, and the rotating drum 15 together with the horizontal shaft body 13 starts rotating around the horizontal shaft 16 at a speed corresponding to the dyeing. As an example, when the diameter of the rotating drum 15 is 1400 mm, the rotating speed of the rotating drum 15 is preferably 6 to 7 rpm, and is 9 rpm at the maximum. Further, when the diameter of the rotating drum 15 is 700 mm, it is preferably 15 rpm. The rotating direction of the rotating drum 15 is counterclockwise in FIG.

  When the rotary drum 15 rotates, the workpiece 26 moves upward while being locked by the locking rib 19, and the workpiece 26 falls into the rotary drum 15 while the rotary drum 15 is rotating, to some extent. The impact is given. The workpiece 26 once dropped is moved upward again by the rotation of the rotary drum 15 and dropped, and is immersed in the treatment liquid 24 while being given a certain level of impact. While the rotary drum 15 is rotating, the workpiece 26 is dyed while repeating the above operation.

On the other hand, as a separate operation from the rotation of the rotating drum 15, the processing liquid 24 circulates in the circulation path 31 by driving the pump 33. That is, by driving the pump 33, the fluid 27 (equivalent to the processing liquid 24 in this case) is ejected from the fluid ejection ends (ejection ports) 32 of the ejection nozzles 30A and 30B at a predetermined speed and flow rate.
The ejection nozzles 30 </ b> A and 30 </ b> B are configured such that the fluid 27 is ejected from the fluid ejection end 32 at the tip portion toward the rotation center of the rotary drum 15 from below with respect to the processing liquid 24 in the rotary drum 15. Has been. The ejection nozzles 30 </ b> A and 30 </ b> B are provided so that the fluid ejection end 32 is in the same cross section as the predetermined hole group 25 in the rotary drum 15, and the hole group 25 in the peripheral wall 22 of the rotary drum 15. Is formed by the circumferentially spaced punching holes 23, so that the fluid 27 is directly ejected into the rotary drum 15 while the fluid ejection end 32 faces the punching hole 23 during the rotation of the rotary drum 15. While the processing liquid 24 in the rotary drum 15 is agitated, the fluid 27 is ejected toward the object to be processed 26, so that a moving force is applied to the object to be processed 26 by the ejected energy, and soot is generated on the object to be processed 26. The position of the portion is effectively changed, and the kneading operation is performed.

In a state where the rotary drum 15 rotates and the fluid ejection end 32 faces the punching holes 23, the fluid 27 is not directly ejected into the rotary drum 15, and the fluid ejection end 32 is caused to rotate by the rotation of the rotary drum 15. When in a state of facing the punching hole 23, the fluid 27 is repeatedly ejected directly into the rotary drum 15.
In other words, the operation in which the fluid 27 is ejected into the rotating drum 15 or not ejected while the rotating drum 15 is rotating is repeated. As a result, a periodic flow (pulsation) is generated in the processing liquid 24 in the rotary drum 15, and the stagnation with respect to the processing object 26, that is, the degree of uniformly holding the entire processing object is improved.
Further, in this embodiment, in order to obtain a more uniform dyeing property, the rotating drum 15 is continuously rotated in the counterclockwise direction which is one direction, and then rotated in the clockwise direction which is the other direction.

  The ejection nozzles 30A and 30B are arranged in a pair of left and right within the range of 80 ° in the circumferential direction from the position P immediately below, and eject the fluid 27 from the ejection nozzles 30A and 30B on both sides. When rotating in the clockwise direction, the liquid level 24a of the processing liquid 24 is leveled, so that it rises to the right, that is, from the position P directly below, the rotational direction side of the rotary drum 15 rises. Therefore, it is conceivable that the agitation that the fluid 27 ejected from the left and right ejection nozzles 30 </ b> A and 30 </ b> B gives to the treatment liquid 24 and the workpiece 26 is different. However, if at least the fluid 27 from the ejection nozzle 30A in the right side row is ejected from the lower side with respect to the treatment liquid 24 and the stirring property of the treatment liquid 24 and the object 26 in the treatment liquid 24 can be secured, Realization of uniform dyeability can be ensured.

  Such an operational effect is that when the rotary drum 15 is rotated in the clockwise direction, the functions of the left and right ejection nozzles 30A and 30B are reversed, and the fluid 27 from the ejection nozzle 30B in the left column is treated with the treatment liquid 24. On the other hand, if the stirring property of the processing liquid 24 and the object to be processed 26 in the processing liquid 24 can be secured, the uniform dyeability can be ensured.

As described above, according to the embodiment of the present invention, the object to be processed 26 is dyed by both the operation accompanying the rotation of the rotary drum 15 and the operation accompanying the ejection of the fluid 27. Uniformity can be improved.
Further, since the object to be processed 26 is dyed by both the operation accompanying the rotation of the rotary drum 15 and the operation accompanying the ejection of the fluid 27, the bath ratio which is the ratio of the amount of the object to be processed 26 and the amount of the processing liquid 24. Can be reduced (low bath ratio), and the running cost can be reduced.

Depending on the material, there is an object to be processed 26 that requires processing at a high bath ratio. However, since the fluid 27 is ejected upward from the lower side of the processing liquid 24, the fluid 27 is injected from the upper side of the processing liquid 24. Compared to the conventional case, the stirring property of the treatment liquid 24 is good, and therefore, even when the workpiece 26 requiring treatment at a relatively high bath ratio is handled, the bath ratio is lower than that in the prior art. And can be dyed.
Furthermore, by setting the bath ratio to be lower than that in the prior art, it is possible to reduce the thermal energy for raising and maintaining the treatment liquid 24 to a necessary temperature, and in this respect also, the running cost can be reduced. .

In addition, since the object to be processed 26 is dyed by both the operation associated with the rotation of the rotating drum 15 and the operation associated with the ejection of the fluid 27, the object to be processed can be achieved even if the rotational speed of the rotating drum 15 is reduced as compared with the past. Therefore, the impact (damage) applied to the workpiece 26 can be reduced by reducing the rotational speed of the rotary drum 15.
Particularly, in the rotary drum 15 of the type provided with the locking rib 19, the impact applied to the workpiece 26 is increased by the amount provided with the locking rib 19, and the workpiece 26 is damaged by the impact during the dyeing operation. As for the point that it is necessary to suppress the above, it is possible to eliminate such a concern by reducing the rotation speed of the rotary drum 15.

  The position of the fluid ejection end 32 of the ejection nozzles 30A and 30B is not particularly limited as long as the predetermined angle θ is within the above range, but the predetermined angle θ is determined depending on the material of the object to be treated 26 and the processing liquid 24. In consideration of conditions such as the amount of rotation and the rotation speed of the rotary drum 15, it is preferable to set the position where the stirring efficiency is the best (uniform dyeing is possible), and the ejection speed and flow rate of the fluid 27 are the same. .

The present invention is not limited to the above-described embodiment, and many configuration changes can be made within the scope of the present invention.
For example, in the above-described embodiment, the jet nozzles 30A and 30B are arranged in a pair of left and right within the range of a predetermined angle θ from the position P directly below the outer peripheral surface of the peripheral wall 22 of the rotary drum 15 and a pair in the direction of the horizontal axis 16 in the direction of the horizontal axis. ing. However, in addition to this, it is also possible to arrange at a position P directly below the outer peripheral surface of the peripheral wall 22 so as to eject the fluid 27 into the rotary drum 15. In this case, when the rotating drum 15 is rotating counterclockwise, the treatment liquid 24 and the treatment liquid 24 are ejected by the ejection of the fluid 27 from the ejection nozzle (not shown) at the position P immediately below and the ejection nozzle 30A in the right side row. When the object to be treated 26 is sufficiently stirred in the treatment liquid 24 and the rotary drum 15 is rotating in the clockwise direction, the treatment is performed by the ejection of the fluid 27 from the ejection nozzles 30 located immediately below the position P and the ejection nozzles 30B on the left side. The workpiece 26 can be configured to be sufficiently stirred in the liquid 24 and the processing liquid 24.

In this way, three or more rows of ejection nozzles can be provided, and the installation positions of the ejection nozzles are the ejection nozzles spaced apart in the direction of the horizontal axis 16 and circumferentially with respect to the position P directly below. It is also possible to arrange them symmetrically (different angles) in the circumferential direction.
Further, for example, when the rotating drum 15 is rotated counterclockwise, the fluid 27 is ejected only from the right side ejection nozzle 30A, and when the rotating drum 15 is rotated clockwise, the left side ejection nozzle is configured. The configuration including the circulation path 31 can be changed and controlled so that the ejection nozzle used according to the rotation direction of the rotary drum 15 is appropriately selected, such as the configuration in which the fluid 27 is ejected from 30B.

In the above-described embodiment, a case where a large number of punching holes 23 having the same diameter are formed so as to be arranged in the circumferential direction and the horizontal axis direction on the peripheral wall 22 of the rotary drum 15 has been described, but the present invention is not limited to this.
That is, for example, the holes facing the ejection nozzles 30 </ b> A and 30 </ b> B may be formed as long holes, and the long holes may be formed on the peripheral wall 22 of the rotary drum 15 at intervals in the circumferential direction. In this case, the length of the hole in the circumferential direction is increased, and the direct ejection time of the fluid 27 into the rotary drum 15 is increased, and pulsation can be ensured, so that the agitation can be further improved. It becomes possible.

In the above embodiment, the rotating drum 15 selects the counterclockwise rotation or the clockwise rotation to perform the dyeing process, but is not limited thereto. That is, for example, the drive motor 20 can be controlled to perform the dyeing process by controlling the rotating drum 15 to swing around the horizontal axis 16 at a predetermined angle. In this case, the punching hole 23 or the long hole does not necessarily have to be formed on the entire surface of the peripheral wall 22, and may be formed only in a region corresponding to the swing angle.
The fluid ejection end 32 of the ejection nozzle is not limited to a configuration opened in a circular shape, and may have a certain length along the circumferential direction of the circumferential wall 22 of the rotary drum 15. When the punching hole 23 is formed, the fluid 27 can be ejected from the opposing punching hole 23 into the rotary drum 15 according to the length of the fluid ejection end 32, and the processing liquid 24 can be pulsated. It becomes.

Furthermore, in the said embodiment, although the ejection nozzles 30A and 30B were fixed to the surrounding wall 21 of the dyeing tank 5, it is not limited to this.
That is, for example, as shown in the enlarged front view of FIG. 4, the nozzle body 34 (the tip portion of the ejection nozzles 30 </ b> A and 30 </ b> B) is fixed to the peripheral wall 22 so that the fluid ejection end 32 opens into the rotary drum 15. Also good. In this case, the nozzle body 34 and the pump 33 side are provided by the flexible connecting pipe 50 having a predetermined length in the radial gap B so that the fluid 27 pumped from the pump 33 can be supplied to the nozzle body 34 side. And connect.
In this way, when the rotating drum 15 is swung, a connection pipe 50 expands and contracts the rotating drum 15 without hindering the swinging operation, and means for directly supplying the processing liquid 24 to the rotating drum 15 is provided.
