[Industrial applications]

 The present invention relates to a knitting 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]

[Prior art]

 In general, knitted fabrics called knitted fabrics (huge and small) have the property of being easily stretched by a tensile force in any of the longitudinal and lateral directions because of their chain-shaped knitting structure. 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 winching machine or a cylinder that processes the fabric with an oval mouse wheel. A liquid flow processing machine or a flow-running processing machine, which processes the cloth put in the shape with a liquid that is flown by a pump, is mainly used.

[0003]

[Problems to be solved by the device]

 However, any of the above-mentioned devices is a so-called rope method in which a long strip of knitted fabric is folded in the width direction to be processed into a string shape. Requires work to do. In addition, since the knitted fabric is processed in the form of a cord, there is a drawback that it is entangled when the processing speed is increased, and because the fabric cannot be processed continuously due to the structure of the device, work efficiency is extremely low. is there.

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

Furthermore, 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 apparatus itself becomes large, and a large amount of cost is required.

The present invention has been made in view of the above-mentioned conventional problems, and it is possible to continuously process a knitted fabric in an expanded state, and moreover, it is highly efficient and inexpensive due to a small device. It is a technical object to provide a knitted fabric processing apparatus that can be processed at low cost.

[0007]

[Means for Solving the Problems]

 In this invention, as a means for achieving the above-mentioned problems, a knitted fabric processing device is configured as follows. That is, in a device for processing a long knitted fabric made of knitted fabrics such as bleaching, dyeing and finish washing, the wound knitted fabric is driven to rotate in a steam chamber that allows the knitted fabric to pass continuously. A plurality of cylinders to be transferred by means of, and equipped with an adjusting mechanism for adjusting the rotational speed of each of the cylinders so as to become slower or faster sequentially in the transfer direction of the knitted fabric. A knitting fabric processing apparatus is configured by providing a vibration drive source for transmitting vibrations, and providing water tanks for moving the knitted fabric while immersing the knitted fabric in water at the inlet and outlet of the knitted fabric in the steam chamber. Use as a summary.

Further, a sprinkling device for pouring water into the knitted fabric in a transition state can be provided in the steam chamber. In this case, an inclination for transferring the knitted fabric together with running water to a position below the sprinkling device. It is preferable to dispose an inclined receiver composed of a surface and a water receiving portion provided below the inclined surface.

In the knitted fabric processing apparatus having the above configuration, the knitted fabric is carried into the steam chamber while being immersed in the water tank on the inlet side, transferred by the rotational drive of the cylindrical body, and transferred to the water tank on the outlet side of the steam chamber. It is discharged while being immersed. In the process of passing through the steam chamber, the knitted fabric is heated by the steam filling the steam chamber. The heating by the steam causes the knitted fabric to have the same temperature as compared with the conventional case of immersing the knitted fabric in hot water. The heat energy required for this is much less. 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 wound around the cylindrical body by the vibration of the transferred cylindrical body and is being transferred. The knitted fabric is also vibrated to accelerate the reaction with the wash water or the 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 is in a water seal form that is shielded from the outside air. Is saturated with saturated steam, and the knitted fabric is heated rapidly. Then, the rotational speed of each of the plurality of cylindrical bodies 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. By gradually delaying from the inlet side toward the outlet side, the pulling force of the knitted fabric in the transport direction is alleviated, and wrinkles and fold-like folds on both sides can be prevented. 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 processing can be performed with high efficiency.

Further, a structure is provided in which a knitting fabric in a transition state is filled with water by a watering device, and an inclined receiver composed of an inclined surface and a water receiving portion for transferring the knitted fabric together with running water is provided below the watering device. In this case, the water sprinkling from the water sprinkling device flushes the dirt and unreacted substances floating on the surface of the knitted fabric in the steam chamber, and then flows down along the inclined receiver along with the water pouring from the water sprinkling device. As a result, the cleaning effect is further improved.

【Example】

 Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a vertical cross-sectional view showing a schematic configuration of a knitted 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, a steam supply pipe 2 is inserted into one side wall 1a of an upper portion of a steam chamber 1 which is a main body of the apparatus, and a steam discharge pipe 3 is led out from another 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 sealed from the outside air.

Both the water tanks 6 and 7 serve as an inlet and an outlet of the knitted fabric 8 with respect to the steam chamber 1, and guide rolls 9 and 10 are arranged in the water tanks 6 and 7, respectively. The knitted fabrics 8 introduced into the steam chamber 1 through the inlet-side outer guide rolls 11, the guide rolls 9 in the water tank 6 and the inlet-side inner guide rolls 12 are alternately arranged diagonally upward 6 Each of the mesh-like porous cylinders 13 to 18 and the vibrating cylinders 19 and 20 is wound around one by one, and the cylinders 13 to 20 are rotationally driven to be transferred upward. A high-frequency or low-frequency vibration force is transmitted to each of the cylindrical bodies 13 to 20 by a vibration drive source (not shown) such as a vibration motor, so that they 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.

The knitted fabric 8 from the porous cylinder 18 at the final stage is wound around the first feeding roll 23 for fabric transport via the two guide rolls 21 and 22, and the first lower roll 23 is provided. It is hung on the inclined receiver 24. The first inclined receiver 24 is composed of a curved inclined surface 24a, a dish-shaped water receiving portion 24b, and an overflow carrying-out trough portion 24c, and is provided above the inclined surface 24a. The knitted fabric 8 is caused to flow along the inclined surface 24a together with the water injected in the shower shape from the first water spraying device 25 including the water injection pipe provided, and the water that has flowed down is retained in the water receiving portion 24b. Then, the knitted fabric 8 is immersed in this accumulated water. Similar to the first feeding roll 23, the first inclined receiver 24 and the first watering device 25, the second and third feeding rolls 26 and 29, the second and third inclined receivers 27, 30, second and third sprinklers 28, 31 are continuously arranged downward. Note that each of the inclined receivers 27 and 30 has inclined surfaces 27a and 30a, water receiving portions 27b and 30b, and trough portions 27c and 30c, respectively, like the first inclined receiver 24.

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 outlet side inner guide roll 33 and the guide roll in the water tank 7 are pulled up. After being discharged to the outside of the steam chamber 1 via the roll 10, the diameter is gradually reduced from the center to both sides by the expander roll 34, and the spread is further ensured, and a pair of squeezing rolls 35, 36 are used. It is squeezed and sent to the next step, for example, the drying step. A watering device 37 is arranged above the expander roll 34, and the final water washing is performed. In addition, sprinklers 38 and 39 are also disposed above the knitted fabric 8 between the above-described vibrating cylinders 19 and 20 and their subsequent porous cylinders 15 and 18, respectively.

Next, the operation of the processing apparatus will be described. First, the knitted fabric 8 in the expanded state that has passed through the inlet side water tank 6 while being immersed in water and entered the steam chamber 1 is transferred upward by the respective cylindrical bodies 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. By the fact that the knitted fabric 8 is transferred in the expanded state, the knitted fabric 8 expands and contracts according to its material. Therefore, when the knitting fabric 8 is made of a material that can be stretched, the rotation speed of each of the cylinders 13 to 20 is sequentially increased from the inlet side to the outlet side by the adjusting mechanism, and conversely. When the cloth 8 is a material that contracts, the rotational speed of each of the cylindrical bodies 13 to 20 is gradually decreased from the inlet side to the outlet side. By doing so, the pulling force of the knitted fabric 8 in the transport direction can be reduced as much as possible, and wrinkles of the knitted fabric 8 and breakage of both sides can be prevented. Furthermore, the knitted fabric 8 is also formed by arranging the cylindrical bodies 13 to 20 and the guide rolls 12, 21 and 22 in close proximity to each other to reduce the distance between them so that the knitted fabric 8 floats in space. It prevents the breakage of both sides.

Further, 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 greatly reduced and the thermal energy is remarkably small, as compared with the case where the knitted fabric 8 is heated in warm water as in the conventional apparatus. Then, each of the cylindrical bodies 19, 20 has a high frequency of 7,200 r. p. m. The vibration of the knitted fabric 8 is transmitted in saturated steam at 100 ° C. for 7,200 r. p. m. Vibration is given. This vibration causes a force to physically pull out dirt, impurities, and unreacted substances existing inside the fiber to the outside, which causes the impurities to float on the fiber surface and Impurities etc. are washed away by water injection of the water sprinkling devices 38, 39. Further, the knitted fabric 8 flows on the respective inclined surfaces 24a, 27a, 30a of the inclined receivers 24, 27, 30 together with the water injection from the water spraying devices 23, 28, 31, and at the same time, the water receiving portions 24b, 27b. By soaking in the accumulated water of 30b, the remaining impurities are eluted into the water and the cleaning effect is remarkably improved.

The knitted fabric 8 washed in this way is led out to the outside through the outlet side water tank 7, and further expanded by the expander roll 34, and at the same time, the final washing is performed by the water sprinkling device 37. After being squeezed by the pair of squeezing rolls 35 and 36, it is sent to the next step.

Further, the water overflowing from the water receiving portions 24b, 27b, 30b of the inclined receivers 24, 27, 30 through the trough portions 24c, 27c, 30c, respectively, flows along the inclined bottom surface of the steam chamber 1. It flows in the direction of the arrow, enters the water tank 6 on the inlet side, and is reused as washing water to save water.

Although the knitting fabric processing apparatus of the present invention is configured as described above, the scope of the present invention is not limited by the above description and the contents of the drawings, and various modifications are possible without departing from the scope of the invention. Modifications of For example, the arrangement position and the number of the cylindrical bodies 13 to 20 and the tilt receivers 24, 27, 30 can be changed or increased or decreased as necessary. In addition, if the inclined receivers 24, 27, 30 are also vibrated, the cleaning effect is further improved. In this case, the inclined surfaces 24a, 27a, 30a and the water receiving portions 24b, 27b, 30b are not separated. It is also possible to separate and give vibration. Further, in the above-mentioned embodiment, the case where it is applied to the washing step is illustrated, but it is needless to say that the same effect can be obtained by applying it to the bleaching or dyeing step. By giving it, the reaction with the processing chemical is promoted.

That is, according to the knitted fabric processing apparatus of the present invention, the knitted fabric can be continuously processed in a long state and can be processed in a spread state, so that the work efficiency is significantly improved. At the same time, the device itself can be downsized, and the operating cost for processing is greatly reduced. In addition, a remarkable treatment effect can be obtained by applying steam and applying vibration. Further, since the rotational speeds of the plurality of cylinders are adjusted so as to become 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.
