[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a dyeing machine.

[0002]

[Prior art]

 A conventional dyeing machine has a sealed chamber, in which a dyeing liquid is stored, and a long cloth to be dyed is circulated while being immersed in the dyeing liquid. In such a dyeing machine, the cloth moves by its own weight and the buoyancy and thrust of the flowing dyeing liquid, in addition to the feeding by the cloth guide roll.

[0003] The above conventional dyeing machine has the following disadvantages. 1. Since a large amount of dye liquor is required to move the cloth, the consumption of dyes and auxiliaries is high, and the amount of waste liquor that must be treated also increases. 2. The fabric tends to sink to the bottom of the chamber, resulting in the fabric rubbing against the bottom and sides of the chamber, fuzzing and damaging the walls of the dyeing machine. 3. Since the cloth is stirred in a large amount of dye liquor, it is easily entangled with each other. 4. Thick and heavy cloths are difficult to move, and may cause poor circulation. 5. It is difficult to adjust the amount of the liquor and control the circulation with respect to the weight and thickness of the cloth, the reproducibility is poor, and dye spots are likely to occur.

[0004]

 An object of the present invention is to provide a dyeing machine which does not require a large amount of dyeing liquid, can smoothly transport a cloth to be dyed without being damaged, and does not damage the apparatus and has a beautiful dyeing finish.

[0005]

[Means for Solving the Problems]

 The dyeing machine according to the present invention includes a chamber for storing a dye solution, and a transport path connecting the front end and the rear end of the chamber. A circulation path is formed by the chamber and the transport path. A cloth guide roll and dyeing nozzle are installed facing the front end, and a conveyor is installed at the bottom of the chamber to transport the cloth from the rear end to the front end of the chamber. By transporting the cloth in the chamber on a conveyor without relying on the liquor, the amount of the liquor can be reduced, and the cloth circulates smoothly regardless of the thickness, weight or amount of the liquor. Also, the conveyor blocks the contact between the cloth and the bottom of the chamber.

Before and after the conveyor, a cloth guide plate or a small conveyor that rotates in the same direction as the conveyor can be erected toward the cloth guide roll and the discharge port of the transport path, respectively. By doing so, the cloth can be transported more smoothly. When the conveyor speed is high, at least the front guide plate among the cloth guide plates is pushed by the accumulated cloth to be able to swing, and the cloth guide plate is operated by contact with the cloth guide plate at the swing point. It is also possible to provide a sensor and to connect the sensor and the conveyor with a control device for decelerating or stopping the conveyor when the sensor is activated. As a result, it is possible to prevent defective transport of the cloth. The small conveyor and the conveyor may be a belt conveyor. It is preferable to rotate the conveyor and the cloth guide roll synchronously.

[Embodiment of the invention]

 FIG. 1 shows a first embodiment of a dyeing machine. The dyeing machine has a chamber 2 for storing a dye solution. A rising portion is formed above the front end of the chamber 2, and a transport path composed of the conduit 3 is provided between the rising portion and the rear end of the chamber 2 so that the rear end thereof is inclined downward. . As a result, the front end and the rear end of the chamber 2 are connected, and a circulation path passing through the chamber 2 and the conduit 3 is formed.

Further, a cloth guide roll 5 is provided inside the rising portion, and a dye solution nozzle 1 is provided slightly below the roll, facing the front end of the conduit 3. The cloth guide roll 5 is driven by a motor to feed the cloth 7 into the conduit 3, and the dye liquid nozzle 1 supplies the dye liquid to the conduit 3. At the bottom of the chamber 2, a conveyor 6 is installed over substantially the entire length thereof. The conveyor 6 is a belt conveyor formed by winding a conveyor belt 62 around a plurality of guide pulleys 61 disposed near the bottom of the chamber 2, and is rotated and driven in synchronization with the cloth guide roll 5. The cloth 7 dropped on the upper surface of the belt 62 is transported from the rear end of the chamber 2 toward the front end.

Before and after the conveyor 6, a fin-shaped front cloth guide plate 63 and a rear cloth guide plate 64, each having a thin bottom, are inclined toward the cloth guide roll 5 and the discharge port of the conduit 3, respectively. It is erected. The front cloth guide plate 63 and the rear cloth guide plate 64 may be flat or may be curved such that the inside is concave. The cloth 7 fed into the conduit 3 by the cloth guide roll 5 enters the rear end of the chamber 2 through the conduit 3 together with the dye supplied from the dye nozzle 1 and is guided by the rear cloth guide plate 64. To fall on the conveyor 2.

Next, while the cloth 7 is conveyed toward the front end of the chamber 2 by the conveyor 2, the cloth 7 is immersed in the dyeing liquid in the chamber 2, guided by the front cloth guide plate 63, and transferred to the cloth guide roll 5. Reach. Further, the cloth 7 circulates in a circulation path constituted by the conduit 3 and the chamber 2 until the cloth 7 is dyed to an appropriate darkness.

Further, when the conveying speed of the conveyor 6 is too high, the front cloth guide plate 63 can be swung forward by being pushed by the accumulated cloth 7 as shown by the broken line in FIG. A sensor 65 is provided at the swinging point of the component cloth guide plate 63 and is activated by contact with the front cloth guide plate 63. Further, a control device (not shown) for decelerating or stopping the conveyor 6 when the sensor 65 operates is connected to the sensor 65 and the conveyor 6. The front cloth guide plate 63 may be biased to automatically return to the original position when the weight of the accumulated cloth 7 is removed.

Therefore, if the speed of the conveyor 6 is too high and the cloth 7 is clogged, the front cloth guide plate 63 swings and the sensor 65 operates, and as a result, the speed of the conveyor 6 decreases and the cloth 7 is deposited. Or, after the conveyor 6 has stopped, the cloth guide roll 5 continues to rotate, the accumulation of the cloth 7 is released, and the front cloth guide plate 63 returns to the original position again. 6 is driven again. The rear cloth guide plate 64 may be fixed, or may swing in conjunction with the front cloth guide plate 63. When the rear cloth guide plate 64 swings together with the front cloth guide plate 63, a sensor 65 may be provided at a swing point of the rear cloth guide plate 64.

FIG. 2 shows a second embodiment of the dyeing machine of the present invention. Before and after the conveyor 6, instead of the front cloth guide plate 63 and the rear cloth guide plate 64, small conveyors 68 are erected so as to be inclined toward the cloth guide roll 5 and the discharge port of the conduit 3, respectively. The small conveyor 68 is a belt conveyor in which a conveyor belt 67 is wound around the outer circumference of a pair of guide rolls 66. The small conveyor 68 is driven to rotate in the same direction as the conveyor 6 at the same speed to drop the cloth 7 dropped from the conduit 3. While being guided to the conveyor 6, the cloth 7 conveyed by the conveyor 6 is guided to the cloth guide roll 5. A sensor for detecting the transport speed of the conveyor 6 may not be provided, or a sensor having a built-in cannula or the like may be provided. Other configurations are almost the same as those of the embodiment shown in FIG. 1, and therefore, the same portions are denoted by the same reference numerals and description thereof will be omitted.

FIG. 3 shows a third embodiment of the dyeing machine of the present invention. This dyeing machine has an arch-shaped chamber 4 that curves downward and protrudes downward along the front-rear direction. At the bottom of the arch-shaped chamber 4, a conveyor 6 which is curved with the same curvature as the curvature thereof is installed over substantially the entire length. The conveyor 6 is a belt conveyor formed by winding a conveyor belt 62 around the outer periphery of a plurality of guide pulleys 61, and transports the cloth along the bottom of the arched chamber 4 from the rear end to the front end. I do. In this embodiment, since the conveyor 6 transports the cloth to a position close to the outlet of the conduit and the cloth guide roll, a cloth guide member such as a cloth guide plate and a small conveyor is unnecessary. Other configurations are almost the same as those shown in FIGS. 1 and 2.

[Effect of the invention]

 According to the structure of the first aspect, it is not necessary to convey the cloth to be dyed by the dyeing liquid, so that the amount of the dyeing liquid can be reduced, and thus the consumption of the dye and the auxiliary agent and the consumption amount of the dye and the auxiliary agent can be reduced. This not only saves energy consumption, but also reduces the amount of waste liquid that needs to be treated, thereby keeping costs low. In addition, since the chamber is not contacted with the cloth by being interrupted by the conveyor, not only does the wall of the chamber not be scratched and scratched, there is no fear that the cloth is fuzzed or torn, and the cloth is agitated in the dye solution and entangled with each other. Absent.

Further, since the amount of the dyeing liquid does not change so much depending on the thickness and weight of the cloth, there is no need to change the capacity of the chamber, and the reproducibility of the dyeing process is high, and dyeing spots are less likely to occur. In addition, since the amount of the dyeing liquid is small, the generation of bubbles can be suppressed, and the cloth can be smoothly circulated in combination with the conveyance on the conveyor.

According to the configuration of the second and fourth aspects, the cloth can be circulated more smoothly. According to the configuration of the third aspect, it is possible to eliminate the poor circulation of the cloth due to the conveyor speed being too high, so that the cloth can be transported more stably and smoothly.
