In the upper portion of the guide portion 47, the injection nozzle 49 for spraying the salt solution, bleach, scouring agent and washing water to the fabric (T) according to the process toward the progress direction of the fabric (T) moving along the guide portion 47 ) Is provided.

The lower part of the dye tank 1 is connected to the discharge pipe 55 for discharging the salt solution and washing water contained in the dye tank 1 to the outside.

The discharge pipe 55 has a drain valve 57 for opening and closing the discharge pipe 55 by an overflow signal among the signals of the level sensing unit 61 for detecting the water level of the dyeing tank 1 and the process of washing. It is installed.

As shown in FIG. 2, the level detecting unit 61 has a sleeve 63, a magnet 71, and a signal generating unit 77.

The sleeve 63 communicates with the sleeve body 65 in which the magnet 71 is liftably received, and the dye tank 1 and the sleeve body 65, and the salt solution of the dye tank 1 is transferred to the sleeve body 65. It has a salt outflow inlet 67 that flows in and out, and an air outlet inlet 69 which communicates the dye tank 1 and the sleeve body 65 while the air in the sleeve body 65 flows in and out of the dye tank 1.

The sleeve body 65 has a hollow cylindrical pipe shape with both ends closed.

The salt solution outlet 67 and the air outlet 69 are formed at predetermined intervals along the longitudinal direction of the sleeve body 65.

The magnet 71 generates a magnetic field and is provided in the buoyancy cylinder 73 accommodated in the sleeve body 65.

As shown in FIG. 3, the buoyancy cylinder 73 has a hollow cylindrical pipe shape in which both ends thereof are closed, and a magnet 71 is accommodated in an inner end of the buoyancy cylinder 73. The buoyancy cylinder 73 is accommodated in the sleeve body 65, the buoyancy acts by the salt solution flows into the sleeve body 65, the buoyancy cylinder 73 is the sleeve body by the salt solution flowing into the sleeve body (65) Go up along 65). Here, the buoyancy cylinder 73 is preferably made of a stainless material excellent in durability and corrosion resistance.

On the other hand, on the outer circumferential surface of the buoyancy cylinder 73, a gap holding portion 75 for maintaining a gap between the buoyancy cylinder 73 and the sleeve body 65 is formed to protrude. In the present embodiment, the space keeping unit 75 protrudes along each circumference of the upper end region and the lower end region of the buoyancy cylinder 73. Thus, when the buoyancy cylinder 73 is moved up and down along the sleeve body 65 by the gap holding portion 75 of the buoyancy cylinder 73, the gap between the buoyancy cylinder 73 and the sleeve body 65 is maintained The shaking of the buoyancy tube 73 is reduced, it is possible to accurately detect the water level of the dye bath (1). Here, it is preferable to install the buoyancy cylinder 73 on the sleeve body 65 so that the magnet 71 faces the air outlet port 69.

The signal generator 77 is provided in plural numbers adjacent to the sleeve 63 along the length direction of the sleeve 63. The signal generator 77 is preferably provided as a proximity sensor that magnetically acts with the magnet 71 to generate an approach signal. The approach signal generated from the signal generator 77 is transmitted to a controller (not shown), which controls the operation of the pump 7 and the opening and closing of the supply valves 11, 13, 15 and the drain valve 57. As such, by arranging the signal generator 77 along the lengthwise direction of the sleeve 63, the height of the salt solution of the dyeing tank 1, that is, the level of the dyeing tank 1 can be detected. It is possible to control the operation of the pump 7 and the valves 11, 13, 15, 57 according to the sensed water level of the.

By this configuration, the supply valves (11, 13, 15) is selectively opened while the winch reel 21 is rotated and the fabric (T) to be dyed in the dyeing tank (1) is circulated, thereby maintaining the main tank (5). And salt water and washing water from the washing water accommodating part 3 are supplied to the dyeing tank 1 through the heat exchanger 9 through the pump 7.

The fabric T circulated by the winch reel 21 is introduced through the fabric inlet 43 of the inner chamber 41, and the washing water or the saline solution contained in the dyeing tank 1 and the weight of the fabric T itself. It is discharged through the fabric outlet 45 of the inner chamber 41 by the buoyancy by circulated in the inner chamber 41.

In general, in order to wash the fabric (T) is performed a number of processes, such as refining process, washing process, bleaching process, dyeing process and post-treatment process. These processes are carried out in a series of orders by the method of dyeing, and some may be omitted. For example, the bleaching process is omitted when the fabric T is to be dyed dark.

Here, the washing process is a process of washing the fabric (T) with the washing water through the washing water is generally performed after the refining process and the bleaching process.

According to each of these processes, the salt solution, the scouring agent, the bleach, and the washing water are withdrawn from the main tank 5 and the washing water receiving portion 3 through the pump 7, and then supplied into the dye bath 1 by the pump 7. , To the fabric (T) guided by the guide portion 47 through the injection nozzle 49.

Then, the washing water sprayed to the fabric (T) through the spray nozzle 49 in the washing process is received in the dyeing tank (1) after washing the fabric (T), the drain valve 57 is the discharge pipe 55 As it is opened, it is discharged out of the dye bath (1).

On the other hand, the dyeing machine according to the present invention, the operation of the pump 7 and the valves 11, 13, 15, 57 is controlled as the level sensing unit detects the water level of the dyeing tank 1 during the above process.

Hereinafter, the dye tank level detection process of the level detecting unit 61 of the dyeing machine according to the present invention will be described.

When the salt solution flows into the sleeve body 65 through the salt solution outlet opening 67 of the sleeve 63, the buoyancy cylinder 73 is raised by the salt solution.

That is, as the height of the salt solution of the dye bath 1 is increased and the salt solution of the dye bath 1 flows into the sleeve body 65, as shown in FIG. 4, the buoyancy cylinder 73 is located above the sleeve 63. Air rising in the buoyancy cylinder 73 and the upper region in the sleeve body 65 is discharged to the dye tank 1 through the air outlet port 69, and at the same time, the magnet 71 accommodated in the buoyancy cylinder 73 Ascending above the sleeve 63 and in line with the signal generator 77 located at the maximum height position, the magnet 71 magnetically acts with the signal generator 77 to cause the dye solution of the dye bath 1 to An access signal is generated to indicate that the level of water is maximum.

On the contrary, as the water level of the salt solution of the dyeing tank 1 is lowered and the salt solution of the sleeve body 65 is discharged to the dyeing tank 1, the buoyancy cylinder 73 descends below the sleeve 63, and the buoyancy cylinder 73 ) And a negative pressure acts on the upper region of the sleeve main body 65 so that the air of the dye bath 1 flows into the sleeve main body 65 through the air inlet 69, and at the same time, a magnet housed in the buoyancy tube 73. When 71 is lowered below the sleeve 63 and aligned in line with the signal generator 77 located at the minimum height position, the magnet 71 magnetically acts with the signal generator 77 so that the dye bath 1 This will generate an approach signal indicating that the salt level in salt is minimal.

Thus, it is possible to detect the level of the salt solution of the dye bath 1, and control the operation of the pump 7 and each valve (11, 13, 15, 57) according to the detected water level of the dye bath (1). Will be.

As such, by providing a level sensing unit having a magnet provided in the dye-staining sleeve flowing out and flowing in and out of the dye-flowing fluid flowing into the sleeve and generating a magnetic field, and a signal generating unit magnetically acting with the magnet to generate an access signal, The level of the dye bath can be detected accurately.

As described above, according to the present invention, by improving the structure of the level detection unit for detecting the level of the dye bath, there is provided a dyeing machine capable of accurately detecting the level of the dye bath.
