Description

  The present invention relates to a fabric pulling device in a liquid flow treatment apparatus for fabric.

  2. Description of the Related Art Conventionally, in a batch type processing apparatus of a liquid dyeing machine that processes endless processing fabric (hereinafter referred to as “fabric”), a traction device for pulling up the fabric is provided between the outlet of the staying section and the processing liquid injection section. It has been. As the traction device, a reel 100 as shown in FIG. 4 and a drum 200 as shown in FIG. 5 are conventionally used.

  The shape of the reel 100 includes a circular side plate 101 provided on both sides and a circle between the side plates 101 having a radius D1 from the center A of the side plate 101 (a circle indicated by an imaginary line C). ) And pipes 102 of outer diameters 20A to 25A installed at equal intervals, and the reel outer diameter 2 × D1 is 200 mm to 300 mm.

  The drum 200 has a shape in which a circular side plate 201 provided on both sides and a non-opening drum portion (cylindrical portion) 202 are concentrically joined to each other. The outer diameter D3 is 200 mm to 300 mm.

  In the conventional reel 100, since the distance D2 between the pipes 102 is large and the opening space 103 is wide, the moisture of the fabric 104 is excessively removed by the opening space 103, so that the reel 100 and the fabric 104 slip. The feeding force of the fabric 104 is small.

  However, since the open space 103 between the pipes 102 is wide and the fabrics 104 are in contact with the pipes 102 in a line, the fabrics 104 are bent at the pipes 102 as shown in FIG. As 104 is pulled, the surface of fabric 104 is rubbed. Further, since the contact area between the fabric 104 and the reel 100 is small, the tension applied from the reel 100 to the fabric 104 is high. This high tension and ironing cause wrinkles and threads in delicate fabrics with very fine fibers, and this impairs the quality of the fabric.

  On the other hand, in the drum part 202 having no opening, since the entire surface of the drum part 202 is in contact with the fabric, the contact area is large, the tension applied to the fabric of the drum part 202 is suppressed, and a delicate fabric with thin fibers is treated. can do.

  However, in the drum portion 202 of the drum 200, since the liquid possessed by the fabric, the brought-in liquid for lifting, and the air between the fabric and the drum portion are not removed, a water film is formed between the drum portion 202 and the fabric. As a result, the water film does not transmit the rotational force of the drum 200 to the fabric, causing a slip, and the fabric pulling force is weak. Further, in a normal fabric with thick fibers, the occurrence of slip is irregular, and the relationship between the fabric feed speed and the drum rotation speed is not stable, and the fabric is rubbed at the contact surface between the fabric and the drum portion 202, causing the It causes wrinkles and has a problem in terms of versatility because the thickness of the fiber that can be treated is limited.

  Therefore, an object of the present invention is to provide a fabric pulling device that ensures the pulling force of the fabric without being affected by the thickness of the fiber and that causes little damage to the fabric.

In order to solve the above-mentioned problems, the invention according to claim 1 is characterized in that an endless processing fabric (hereinafter referred to as a fabric) is installed in an annular passage composed of a retention portion and a transfer pipe, and the fabric pulling device and the processing liquid are disposed. In the liquid flow type processing apparatus of the cloth which is made to circulate and process by injection,
The fabric pulling device includes a drum portion provided between the upper portion of the staying portion outlet and the treatment liquid ejecting portion and provided perpendicular to the fabric transition direction, and a driving unit that rotates the drum portion. And
The drum portion is provided with openings along the axial direction of the drum portion, and a plurality of openings are formed at predetermined intervals in the circumferential direction of the drum portion.

  According to a second aspect of the present invention, in the first aspect of the present invention, the opening has a slit shape along the axial direction of the drum portion.

  According to the present invention, by providing the opening in the drum portion of the fabric pulling device, it is possible to remove moisture from the fabric while ensuring a large contact area between the fabric and the drum portion of the fabric pulling device.

  Therefore, by increasing the contact area between the fabric and the drum portion of the fabric pulling device as compared with the conventional reel, the tension applied to the fabric from the drum portion can be reduced, and the occurrence and degree of thread and wrinkle in the fabric can be reduced. And a decrease in the commercial value of the fabric can be suppressed.

  Further, since moisture is removed from the fabric, the formation of a water film between the fabric and the drum portion of the fabric pulling device is suppressed more than the conventional drum, and the occurrence of slip is suppressed and the thickness of the fiber is affected. Therefore, the fabric can be pulled stably and reliably. Further, since the occurrence of slip can be suppressed, rubbing between the fabric and the drum portion of the fabric pulling device can be suppressed, and the occurrence of the fabric thread and wrinkle can be suppressed.

  Therefore, it is possible to perform pulling that combines the advantages of the reel and the drum, the versatility of various fabrics is high, and the quality of the fabric can be improved.

The best mode for carrying out the present invention will be described based on the embodiment shown in FIGS.
FIG. 1 is a schematic side sectional view of a liquid flow treatment apparatus 1 for fabric.

  The cloth liquid flow processing apparatus 1 has a staying tank 2, and the staying tank 2 includes a staying part 2a and a slope part 2b provided at the outlet of the staying part 2a. A box 3 is provided above the exit of the slope portion 2 b, that is, above the staying portion outlet, and a processing liquid injection unit 4 is provided below the box 3. Inside the box 3, a fabric pulling member 5 is provided.

  The fabric pulling member 5 is rotated counterclockwise in FIG. 1 by a driving means M such as a transmission motor. The fabric pulling member 5 and the driving means M constitute a fabric pulling device 5A.

  The upstream side of the transfer pipe 6 is connected to the lower part of the processing liquid injection unit 4, and the downstream side is connected to the inlet 2 c of the retention tank 2. An annular processing path is formed by the staying tank 2, the box 3, the processing liquid injection unit 4, and the transfer pipe 6.

  The treatment fabric 7 (hereinafter referred to as “fabric”) joined endlessly temporarily stays while moving in a meandering manner in the treatment liquid 8 of the stagnation portion 2a, and the fabric is pulled by the drive means M such as a transmission motor. By the rotation of the member 5, it is pulled up along the slope 2 b from the stagnation part 2 a, moves in the transfer pipe 6 together with the processing liquid 8 injected from the processing liquid injection part 4, and from the staying tank inlet 2 c that is the downstream end. It is sent again to the stagnation part 2a of the retention tank 2 and circulates.

  The treatment liquid 8 is sucked into the heat exchanger 13 through the discharge pipe 12 from the bottom 2d of the retention part 2a through the suction pipe 10 for the treatment liquid, enters the heat exchanger 13 through the discharge pipe 12, and is heated to a required temperature. The treatment liquid is injected into the treatment liquid injection unit 4 through the pipe 14, and the injection pressure is adjusted by the flow rate adjustment valve 15 and injected to the fabric 7.

  The processing liquid 8 is sprayed downward in FIG. 1 from the processing liquid injection unit 4, passes through the transfer pipe 6, returns to the retention part 2 a of the retention tank 2 from the retention tank inlet 2 c, and the fabric along with the flow of the processing liquid 8 7 is transferred.

Next, the fabric pulling member 5 of the cloth pulling device 5A will be described with reference to FIGS.
The fabric pulling member 5 includes a pair of circular side plates 20 and a cylindrical drum portion (traction portion) 21 provided therebetween, and the drum portion 21 is formed in a circular shape concentric with the center of the side plate 20. In addition, the drum portion 21 is provided with an opening (gap) 22 penetrating in and out of the drum portion 21 in the axial direction of the drum portion 21, that is, in a direction perpendicular to the traveling direction of the fabric 7. In the present embodiment, the opening 22 is formed in a slit shape that is long in the axial direction of the drum portion 21, and the opening 22 is provided over the entire length between the circular side plates 20, 20, but contacts the fabric 7. You may provide the opening part 22 only in the part.

  A plurality of the openings 22 are provided in the circumferential direction of the drum portion 21 with appropriate intervals.

  The outer diameter D4 of the drum portion 21 is arbitrarily set. In the present embodiment, the outer diameter D4 is set to 200 mm to 300 mm.

  The gap D5 of the slit-like opening 22 is arbitrarily set, but is 3 mm to 20 mm, preferably 6 mm to 13 mm. In this embodiment, it is set to 10 mm. If the gap D5 of the slit-shaped opening 22 is wider than 20 mm, the fabric 7 bends at the opening end 22a, and if slip occurs between the fabric 7 and the drum portion 21 of the fabric pulling member 5 in this state, the opening The fabric 7 is rubbed at the end 22a, causing the fabric 7 to be threaded or wrinkled. If the gap D5 is narrower than 3 mm, water removal from the opening 22 is insufficient, and a water film may be formed between the fabric 7 and the drum portion 21 of the fabric pulling member 5, and a water film is generated. This is because the pulling force by the cloth pulling member 5 is not transmitted to the cloth 7 and slipping occurs, and the force pulling the cloth 7 is weakened.

  The number of openings 22 in the circumferential direction is preferably 6 to 10, and is set to 8 in this embodiment. When the number of the openings 22 is too large, the contact area between the drum portion 21 of the fabric pulling member 5 and the fabric 7 decreases. For this reason, the fabric 7 is bent at the opening end 22a of the opening 22 and the fabric 7 is not squeezed by the fabric pulling member 5 or the tension applied to the fabric 7 from the fabric pulling member 5 is not dispersed. No. 7 causes threading and wrinkling, and the product value is reduced. If the number of the openings 22 is too small, water removal from the fabric 7 is insufficient and a water film may be formed between the fabric 7 and the drum portion 21 of the fabric pulling device 5, resulting in the above-described problems. . Therefore, when the diameter D4 of the drum portion 21 is set as described above as in the embodiment, the number of the openings 22 is preferably the above value.

  In addition, if the opening end 22a of the opening 22 is formed in a square shape, the cloth 7 may be damaged by the corner, and therefore the opening end 22a is formed in a curved surface in the embodiment. Thus, damage to the fabric 7 is suppressed.

  In order to form the drum portion 21 having the opening 22 as described above, in this embodiment, as shown in FIG. 3, the arc portion 21a formed of an arc having a radius centered on the center A, and the arc A plurality of divided bodies 21c formed by integrally forming bent portions 21b formed by bending both ends in the circumferential direction of the portion 21a from a metal plate, in the embodiment, eight pieces, are arranged in the circumferential direction so that the drum portion (traction portion) 21 is provided. It is composed. Then, both ends of each divided body 21c are fixed to the side plate 20 by welding.

  With the above structure, when the fabric 7 is towed, moisture of the fabric 7 can be removed while ensuring a contact area between the fabric 7 and the drum portion 21 of the fabric pulling member 5 as large as possible.

  In the conventional drum 200, since a water film is generated between the drum portion 202 and the fabric, stable pulling cannot be performed, and therefore, the slip between the fabric and the drum portion 202 causes wrinkles and threads, and cannot be processed. The thickness of the fabric fiber was present. However, by using the fabric pulling member 5 of the present invention, water is removed from the fabric 7 and a water film that causes slippage does not occur between the fabric 7 and the drum portion 21 of the fabric pulling member 5. The traction force can be ensured in fabrics such as woven fabrics and blended fabrics such as nylon and polyester, knitted fabrics and blended knitted fabrics such as nylon and polyester, and fabrics and knitted fabrics of composite material fibers without being affected by the thickness of the fibers.

  Further, in the conventional reel 100, the fabric is in line contact with the reel and the generation of wrinkles and threads is large. However, in the present invention, the fabric 7 can be pulled with a wider contact area, so Can be relaxed.

  Furthermore, even in delicate fabrics with extremely fine fibers, the occurrence and degree of threads and wrinkles can be reduced.

  Therefore, in the present invention, taking advantage of the advantages of the conventional non-opening drum and reel, and having the function of removing the disadvantages of the non-opening drum and reel, the versatility for various fabrics is high. A fabric of good quality can be provided.

  The driving means M of the fabric pulling member 5 includes an inverter that controls the number of rotations of the fabric pulling member 5 and a rotational torque adjuster that adjusts the rotational torque set to the speed of the drum portion 21. In addition, you may have only any one of an inverter or a torque regulator. Moreover, it is not necessary to have an inverter and a torque regulator.

  By having an inverter and a torque adjuster, the slip between the fabric 7 and the drum portion 21 of the fabric pulling member 5 can be further suppressed, and the generation and extent of threads and wrinkles in delicate fabrics with extremely thin fibers can be reduced. It can be further relaxed.
