BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knitted fabric processing apparatus for processing a long knitted fabric made of a knit, which is particularly susceptible to tension in the field of processing fiber fabrics.

[0002]

2. Description of the Related Art In general, knitted fabrics called knitted fabrics (huge and small) are easily stretched due to a pulling force in both longitudinal and lateral directions due to their chain-like knitting structure. It has the property. Therefore, when processing such as bleaching, dyeing and finishing washing of this knitted fabric, a processing device of a type that does not apply much tension to the fabric to be processed, for example, a wins processing machine that processes the fabric with an oval mouse wheel, a tubular machine liquid flow processing machine subjected to processing with a liquid which is flowing by the pump to fabric placed in a body, or fluid traveling machine is mainly used.

[0003]

However, any of the above-mentioned devices is a so-called rope type processing method in which a long band-shaped knitted fabric is folded in the width direction and processed into a string shape. Therefore, it is necessary to widen the fabric after the treatment. In addition, since the knitted fabric is processed into a string shape, there is a drawback that entangled when the processing speed is increased,
Also, the work efficiency is extremely low because the fabric cannot be continuously processed due to the structure of the device.

Further, as a device for processing a knitted fabric in a spread state, there is a conveyor wins processing machine, but there is a limit to the amount of fabrics that can be accommodated per unit, which is also inefficient.

Further, the structure is such that the cloth is transferred by the treatment water, and a large amount of water is required, and the treatment water is heated by means of mixing steam into the treatment water to accelerate the treatment capacity. Therefore, a large amount of steam is required,
The device itself becomes large in size, and a large amount of cost is required.

The present invention has been made in view of such conventional problems, and can knit a knitted fabric continuously in a spread state, and is highly efficient and inexpensive with a small device. It is a technical object to provide a knitted fabric processing apparatus that can be processed at various costs.

[0007]

As a means for achieving the above-mentioned object, the present invention has a knitting fabric processing apparatus configured as follows. That is, in a device for performing processing such as bleaching, dyeing, and finishing cleaning on a long knitted fabric made of knitted fabric, the knitted fabric wound around the knitted fabric is rotatably driven in a steam chamber that continuously passes the knitted fabric. A plurality of cylinders to be transferred are provided, and an adjusting mechanism is provided to adjust the rotational speed of each of the cylinders so as to be gradually slower or faster in the transfer direction of the knitted fabric. A vibrating drive source for transmission is provided, and a water tank for moving the knitted fabric while immersing the knitted fabric in water is provided at the inlet and the outlet of the knitted fabric in the steam chamber. .

Further, it is possible to provide a watering device for pouring water to the knitted fabric in a transition state in the steam chamber,
In this case, it is preferable to dispose an inclined receiver, which is composed of an inclined surface for transferring the knitted fabric together with running water, and a water receiving portion provided below the inclined surface, at a position below the watering device.

In the knitted fabric processing apparatus having the above structure, the knitted fabric is carried into the steam chamber while being immersed in the water tank on the inlet side, is transferred by the rotational drive of the cylindrical body, and is immersed in the water tank on the outlet side of the steam chamber. While being discharged, it is discharged to the outside of the steam room. In the process of passing through this steam chamber, the knitted fabric is
Although the steam filled in the steam chamber is heated, the heating by this steam requires significantly less heat energy to raise the temperature to the same temperature as compared with the case of immersing the knitted fabric in the conventional hot water. Since the knitted fabric is wound around the cylindrical body and transferred by the rotation of the cylindrical body, the knitted fabric is processed in the spread state and is shaken around the cylindrical body by the vibration of the transferred cylindrical body and is being knitted during transfer. The fabric is also vibrated to promote reaction with the wash water or treatment chemicals.
In addition, since water tanks are provided at the inlet and outlet of the steam chamber and the knitted fabric passes through the water tank to enter and leave the steam chamber, the steam chamber has a water seal form that is shielded from outside air. Is filled with saturated steam, so that the knitted fabric is quickly heated. Then, the rotational speed of each of the plurality of cylinders is gradually increased from the one on the inlet side to the one on the outlet side in the case of the material from which the knitted fabric extends, and in the case of the material from which the knitted fabric shrinks, The pulling force in the transport direction of the knitted fabric is relieved by gradually slowing from the side of the knitted fabric toward the side of the outlet side, and it is possible to prevent wrinkles and fold-like folds on both sides. Further, since the knitted fabric is processed by being continuously fed and passed through in the steam chamber, an extremely long one can be continuously processed, and the processing can be performed with high efficiency.

In addition, a sprinkling device is used to inject water into the knitted fabric in a transitional state, and an inclined receiver, which is composed of an inclined surface and a water receiving portion for transferring the knitted fabric together with running water, is provided below the sprinkling device. In this case, the water sprinkling from the water sprinkling device flushes dirt and unreacted substances floating on the surface of the knitted fabric in the steam chamber, and then flows down along with the water sprinkling from the water sprinkling device along the inclined receiver. As a result, the cleaning effect is further improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a vertical cross-sectional view showing a schematic structure of a knitting fabric processing apparatus according to an embodiment of the present invention, and this embodiment exemplifies a case where finish cleaning is performed. In FIG. 1, one side wall 1 at the upper part of the steam chamber 1 which is the main body of the apparatus
The steam supply pipe 2 is inserted in a, and the steam discharge pipe 3 is led out from the other side wall 1b. The steam from the steam supply pipe 2 is gradually supplied into the steam chamber 1 by the slit plate 4, and the steam discharge pipe 3 is provided with a damper 5 for adjusting the amount of discharged steam. The lower ends of the side walls 1a and 1b of the steam chamber 1 are immersed in water tanks 6 and 7, respectively, so that the water in the water tanks 6 and 7 is shielded from the outside air.

The both water tanks 6 and 7 are knitted fabrics 8 respectively.
The guide rolls 9 and 10 are provided in the water tanks 6 and 7, respectively.
Entrance side external guide roll 11, guide roll 9 in the water tank 6
Further, the knitted fabric 8 introduced into the steam chamber 1 through the inner guide rolls 12 on the inlet side has six meshed porous cylindrical bodies 13 to 18 and vibrations alternately arranged obliquely upward. The cylinders 19 and 20 are sequentially wound around and are moved upward by rotationally driving the cylinders 13 to 20. A vibration driving source (not shown) such as a vibration motor transmits a high-frequency or low-frequency vibration force to each of the cylindrical bodies 13 to 20,
It is supposed to vibrate slightly. Further, an adjusting mechanism (not shown) is provided for adjusting the rotational speed of each of the cylindrical bodies 13 to 20 in accordance with the property of the cloth 8 to be processed.

Knitted fabric 8 from the last stage porous cylinder 18
Is wound around a first feeding roll 23 for fabric transfer via two guide rolls 21 and 22, and is hung on a first inclined receiver 24 below. The first inclined receiver 24 has a curved inclined surface 24a, a dish-shaped water receiving portion 24b,
The knitting fabric 8 is poured together with water injected in the shower form from the first water spraying device 25, which is composed of the overflow carrying-out gutter portion 24c and is provided above the inclined surface 24a, and is formed of a water injection pipe.
It is made to flow along the
It stays in 24b, and the knitted fabric 8 is immersed in this staying water.
The first feeding roll 23, the first inclined receiver 24, and the first
Second and third payout rolls 26 similar to the sprinkler 25 of
29, the 2nd and 3rd inclination receivers 27 and 30, and the 2nd and 3rd sprinkling devices 28 and 31 are continuously arranged below. still,
Similar to the first inclined receiver 24, each inclined receiver 27, 30 includes inclined surfaces 27a, 30a, water receiving portions 27b, 30b and trough portions 27c, 30c, respectively.

The knitted fabric 8 immersed in the water receiving portion 30b of the third inclined receiver 30 is pulled up by the fourth feeding roll 32, and the inner guide roll 33 on the outlet side and the guide roll 10 in the water tank 7 are pulled up. After being led out to the outside of the steam chamber 1 via the expander roll 34, the diameter of which gradually decreases from the central portion toward both sides, the spreader roll 34 is spread more reliably, and the roll is squeezed by a pair of squeeze rolls 35 and 36. It is sent to a process, for example, a drying process. A watering device 37 is arranged above the expander roll 34, and the final water washing is performed. Also, at the upper position of the knitted fabric 8 between the above-mentioned respective vibrating cylinders 19, 20 and their next porous cylinders 15, 18.
Sprinklers 38 and 39 are provided respectively.

Next, the operation of the processing apparatus will be described. First, the knitted fabric 8 in the expanded state that has entered the steam chamber 1 through the inside of the inlet side water tank 6 while being immersed in water is transferred upward by the respective cylinders 13 to 20. In the process of transferring the knitted fabric 8 by 20, the inside of the steam chamber 1 is in the water seal form as described above, so that the steam chamber 1 is filled with saturated steam and maintained at about 100 ° C. And knitted fabric 8
When the knitted fabric 8 is transferred in the spread state,
Expansion and contraction occur depending on the material of it. Therefore, when the knitting fabric 8 is made of a material that can be stretched, the adjusting mechanism causes the rotational speeds of the respective cylinders 13 to 20 to be sequentially increased from those on the inlet side to those on the outlet side, and vice versa. When the cloth 8 is a material that shrinks, the rotation speed of each cylindrical body 13 to 20 is
It will be gradually delayed from the entrance side to the exit side. By doing so, it is possible to reduce the pulling force of the knitted fabric 8 in the transport direction as much as possible, and it is possible to prevent wrinkles of the knitted fabric 8 and folds on both sides thereof from occurring. Furthermore, the cylindrical bodies 13 to 20 and the guide rolls 12, 21 and 22 are arranged close to each other to reduce the distance between them, and the knitted fabric 8 floats in the space to a short distance. Prevents breakage on both sides.

As described above, the knitted fabric 8 is heated by the saturated steam in the steam chamber 1 maintained at 100 ° C. This is because the temperature rising rate is significantly shortened and the heat energy is remarkably small as compared with the case where the knitted fabric 8 is heated in warm water as in the conventional device. And
Each of the cylindrical bodies 19 and 20 has, for example, a high frequency of 7,200
r. p. m. Vibration is transmitted, and the knitted fabric 8 is
7,200 r.p.m. in saturated steam at 100.degree. p. m.
Vibration is given. Due to this vibration, a force that physically pulls out dirt, impurities and unreacted substances existing inside the fiber acts on the outside, which causes those impurities to float on the surface of the fiber, and these impurities, etc. Is washed away by the water sprinklers 38, 39. further,
The knitted fabric 8 flows on the respective inclined surfaces 24a, 27a, 30a of the respective inclined receivers 24, 27, 30 together with the water injection from the sprinkling devices 23, 28, 31 and at the same time, the respective water receiving portions 24b, 27b, 30b. By being immersed in the accumulated water, the remaining impurities and the like are eluted into the water, and the cleaning effect is remarkably improved.

The knitted fabric 8 thus washed is
After being discharged to the outside through the outlet side water tank 7 and further reliably spread by the expander roll 34, at the same time the final washing is performed by the water sprinkling device 37, and after being squeezed by the pair of squeezing rolls 35 and 36, the next step Sent to.

In addition, the water receiving portion 24 of each of the inclined receivers 24, 27, 30
Water overflowing from b, 27b, and 30b through the troughs 24c, 27c, and 30c flows in the arrow direction along the inclined bottom surface of the steam chamber 1, enters the water tank 6 on the inlet side, and is reused as wash water. It is designed to save water.

The knitting fabric processing apparatus of the present invention is constructed as described above, but the scope of the present invention is not limited by the above description and the contents of the drawings.
Various modifications may be included without departing from the gist. For example, the arrangement position and the number of the cylindrical bodies 13 to 20 and the inclined receivers 24, 27, 30 can be changed or increased or decreased as necessary. If the inclined receivers 24, 27, 30 are also vibrated, the cleaning effect is further improved.
It is also possible to separate the inclined surfaces 24a, 27a, 30a and the water receiving portions 24b, 27b, 30b to give vibration. In addition, in the above-mentioned embodiment, the case where the invention is applied to the washing process is illustrated, but it is needless to say that the same effect can be obtained even when applied to the bleaching or dyeing process, and for example, vibration is applied to the knitted fabric. This accelerates the reaction with the treatment chemicals.

[0021]

Since the present invention is constructed and operates as described above, it has the following effects. That is, according to the knitting fabric processing apparatus of the present invention, the knitting fabric can be continuously processed in a long state,
Moreover, since the processing can be performed in the spread state, the working efficiency is significantly improved, the apparatus itself can be downsized, and the operating cost for the processing is significantly reduced. Also,
A significant treatment effect can be obtained by applying steam and vibration. Further, since the rotational speeds of the plurality of cylinders are adjusted so as to be sequentially slower or faster in the transport direction of the knitted fabric, the pulling force in the transport direction of the knitted fabric can be made as small as possible. It is possible to prevent wrinkles and breaks on both sides. Furthermore, saturated steam can be filled in the steam chamber, and thermal energy can be significantly saved.

Further, according to the knitting fabric processing apparatus of each of the second and third aspects of the present invention, a remarkable cleaning effect capable of removing dirt and impurities can be obtained.
