Description

Textile dyeing device and textile dyeing method using the same

The present invention relates to a textile dyeing apparatus and a textile dyeing method using the same, and more particularly, to a textile dyeing apparatus capable of measuring the number of rotations of a textile fabric and a textile dyeing method using the same.

The 4th industrial revolution is starting with smart manufacturing. Among the manufacturing fields, the field with the weakest introduction of ICT technology is the textile (fabric manufacturing, dyeing, processing, footwear, clothing, etc.) field. Many domestic and foreign manufacturing companies are still using manual control facilities, and some automated facilities have been introduced to produce and operate, but the full-scale ICT technology has not been introduced. In particular, in the dyeing processing process, a significant part is produced depending on the know-how of the production operator in many cases.

In relation to the dyeing processing process, a rapid dyeing machine, a normal pressure dyeing machine, a high pressure dyeing machine, or a high pressure dyeing machine is mainly used for dyeing. At this time, setting the rotation RPM and dyeing time of the dyeing machine and adjusting the dyeing method and bath ratio often depended on the know-how of the workers in the production site. Recently, it is possible to dye in which the controller controlling the dyeing machine automatically adjusts rotation RPM, time, dyeing method, and bath ratio. However, even if the dyeing process is performed with the value set by the dyeing machine controller, the fabric in the dyeing machine is immersed in the dye, rotates, and repeats the immersion in the dye (dye, alkali, forget-me-not, soda ash, water, etc.) No technology has been introduced to monitor the rotation process.

The present invention intends to propose a textile dyeing apparatus capable of uniformly dyeing a fabric and a textile dyeing method using the same.

The problem to be solved by the present invention is not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those of ordinary skill in the art from the following description.

The textile dyeing apparatus according to an embodiment of the present invention can accurately measure the number of rotations of the textile fabric through the marking fabric, and can control the dyeing unit through this, so that the entire fabric can be dyed more uniformly.

Hereinafter, a fiber dyeing apparatus and a fiber dyeing method using the same according to embodiments of the present invention will be described in detail with reference to the drawings.

1 is a schematic block diagram for explaining a textile dyeing apparatus according to embodiments of the present invention.

Referring to Figure 1, the textile dyeing apparatus according to the present invention is a dyeing unit 10 for dyeing a textile fabric to which a mark fabric is added, and a rotation measuring the number of times the textile fabric rotates in the dyeing unit 10 through the mark fabric. The number measurement unit 20, the first control unit 30 for calculating the additional rotation speed by comparing the rotation speed measured by the rotation speed measurement unit 20 with the rotation speed input to the dyeing unit 10, and the first control unit It may include a second control unit 40 for inputting the additional rotation number calculated in (30) to the dyeing unit (10). A process in which the first control unit 30 calculates the additional rotation speed and transmits a command to the second control unit 40, and the second control unit 40 drives the dyeing unit 10 will be described in detail with reference to FIG. 2 below. do. In addition, the textile fabric to which the mark fabric is attached will be described in detail later with reference to FIGS. 3 and 4 .

The dyeing unit 10 may perform at least a part of a fiber dyeing process including refining, bleaching, dyeing, processing, and tentering. The dyeing unit 10 may use a normal pressure dyeing machine or a high pressure dyeing machine according to the type of textile fabric. As an example, the atmospheric pressure dyeing machine is used for dyeing cotton fabrics, and dyeing is performed at about 60 degrees. As another example, the high-pressure dyeing machine is used for dyeing spandex fabrics, and dyeing is performed at about 130 degrees. When the dyeing is carried out in the dyeing unit 10, the temperature at which the dyeing is made may be one of the important factors of the dyeing process. The dyeing unit 10 may include a reel around which the textile fabric is wound. As the textile fabric is wound on a reel and rotated, a part thereof may be immersed in a dye provided under the reel, and may be dyed by the dye. Since the textile fabric does not rotate like a reel and a cogwheel, it may not rotate as much as the reel rotates, and accordingly, the rotation speed of the reel and the rotation speed of the textile fabric may not match. For example, the longer the period of use of the dyeing unit 10, the greater the difference between the number of rotations of the reel and the number of rotations of the textile fabric.

The rotation speed measuring unit 20 may include a device for detecting the mark fabric attached to the fabric fabric. For example, the rotation speed measuring unit 20 may include a vision camera, a thermal imaging camera, an IR camera, or a circuit for measuring an electrical signal. The rotation speed measurement unit 20 may measure the rotation speed of the textile fabric, which may be different from the rotation speed of the reel, through the mark fabric.

The first control unit 30 may include a device for calculating the additional rotation speed by comparing the rotation speed measured by the rotation speed measuring unit 20 with the rotation speed initially input to the dyeing unit 10 . The additional rotational speed may be the difference between the rotational speed initially input to the dyeing unit 10 and the rotational speed measured by the rotational speed measuring unit 20 . In this case, the input rotation speed may be the rotation speed of the reel, and the rotation speed measured by the rotation speed measuring unit 20 may be the rotation speed of the textile fabric. The first control unit 30 may transmit the calculated additional rotation speed to the second control unit 40 . As an example, the first control unit 30 may further include a device for calculating the rotation time of the textile fabric.

The second control unit 40 may transmit information including the additional rotation speed calculated by the first control unit 30 to the dyeing unit 10 . As an example, the second control unit 40 may include a manufacturing execution system (MES). The information transmitted by the second control unit 40 to the dyeing unit 10 may include parameters such as, for example, the temperature of the dyeing machine, the dyeing time, the reel RPM, the dyeing method and the bath ratio, as well as the additional rotation speed. The second control unit 40 may control overall driving conditions of the dyeing unit 10 , and for example, may re-enter the additional rotation speed transmitted from the first control unit 30 into the dyeing unit 10 .

2 is a flowchart for explaining a method of controlling the number of rotations in a fiber dyeing method using a fiber dyeing apparatus according to embodiments of the present invention.

1 and 2, in the method of controlling the rotation speed in the fiber dyeing method according to the present invention, the first step (P10) of inputting the rotation speed to the dyeing unit 10, the input rotation speed and the measured rotation speed In the determining step of comparing (D10), if the input rotational speed is greater than the measured rotational speed, the second control unit 40 calculates the additional rotational speed in the second step (P20) and the second step (P20) of calculating the additional rotational speed It may include a third step (P30) of transferring to the, and a fourth step (P40) of terminating the operation of the dyeing unit 10 when the input rotational speed is less than or equal to the measured rotational speed. The determination step D10 and the second step P20 may be performed by the first controller 30 , and the first step P10 and the fourth step P40 may be performed by the second controller 40 . can

The number of rotations input to the dyeing unit 10 in the first step P10 may be transmitted to a reel inside the dyeing unit 10, and the number of times the reel rotates may be determined. The loop returning to the first step P10 through the first step P10, the determination step D10, the second step P20, and the third step P30 is performed when the input rotation speed becomes smaller than the measured rotation speed. can be repeated until While repeating the loop, the textile fabric can be rotated as much as a target number of rotations, and through this, the fabric can be dyed uniformly to the target dyeing degree.

3 is a schematic perspective view for explaining a method of measuring the number of rotations in a fiber dyeing method using a fiber dyeing apparatus according to embodiments of the present invention.

Referring to Figure 3, the method of measuring the number of rotations in the fiber dyeing method according to the present invention is to connect the first fabric 100 and the second fabric 200, the first fabric 100 and the second fabric ( It may include adding the marking fabric 300 to the connection part of the 200 , and sensing the marking fabric 300 through the measuring device 400 .

The first fabric 100 and the second fabric 200 may be, for example, substantially the same fiber fabric. The first fabric 100 and the second fabric 200 may be connected to each other for continuous operation inside the dyeing machine. The first end 100 and the second end 200 may be connected through a sewing machine process. However, what is shown is merely exemplary, and the present invention is not limited thereto, and unlike the drawings, at least three or more fabrics substantially the same as the first and second fabrics 100 and 200 may be connected to each other.

The marking fabric 300 may be, for example, a non-dyed fabric or a temperature-sensitive fabric. The thermosensitive fabric refers to a fabric including a temperature setting type material having a characteristic of maintaining a specific temperature. For example, when the marking fabric 300 is a fabric that is not dyed, the marking fabric 300 may include acetate, nylon, or silk. As another example, when the mark fabric 300 is a temperature-sensitive fabric, the mark fabric 300 can maintain a specific temperature, and can maintain a temperature different from that of the first and second fabrics 100 and 200 inside the dyeing machine. have. For example, the width of the mark fabric 300 may be less than or equal to about 30 cm, and thus may not significantly affect the dyeing process.

For example, when the marking fabric 300 is a fabric that is not dyed, the measuring device 400 may be a vision camera. Since the mark fabric 300 is not dyed by the dyeing material or is dyed in a color different from that of at least the first and second fabrics 100 and 200 , it can be detected by the measuring device 400 .

As another example, when the mark fabric 300 is a temperature-sensitive fabric, the measuring device 400 may be a thermal imaging camera, an IR camera, or a laser-type temperature measuring sensor. Since the mark fabric 300 maintains a temperature different from that of the first and second fabrics 100 and 200 inside the dyeing machine, it can be detected by the measuring device 400 .

The measuring device 400 may measure the number of rotations and the amount of rotation of the textile fabric through the number of times the mark fabric 300 is sensed.

4 is a schematic perspective view for explaining a method of measuring the number of rotations in a fiber dyeing method using a fiber dyeing apparatus according to embodiments of the present invention. For convenience of description, descriptions of items substantially the same as those described with reference to FIG. 3 will be omitted.

Referring to FIG. 4 , the marking fabric 300 may be a conductive fabric. For example, unlike shown in the drawings, the marking fabric 300 is not provided, and a sewing machine process for connecting the first fabric 100 and the second fabric 200 may be performed using a conductive thread. The conductive fabric or conductive yarn may have lower electrical resistance and higher electrical conductivity than the first fabric 100 or the second fabric 200 .

The measuring device 500 may be connected to the first conductive line 310 and the second conductive line 320 , respectively. The measuring device 500 may be an electrical circuit that applies a voltage or current or senses an electrical signal. One end of the first and second conductive lines 310 and 320 may be respectively connected to the positive electrode and the negative electrode of the measuring device 500 . The other ends of the first and second conductive lines 310 and 320 may be respectively connected to the upper surface of the reel. For example, unlike the drawings, the first and second conductive lines 310 and 320 may have a ring shape surrounding a portion of the upper surface of the reel. The measuring device 500 measures the electrical signal transmitted through the first and second conductive lines 310 and 320 at the moment the mark fabric 300 passes between the first and second conductive lines 310 and 320 . It can be detected, and the number of times the mark fabric 300 is sensed can measure the number of rotations and the amount of rotation of the textile fabric.

The textile dyeing apparatus and the textile dyeing method using the same according to the present invention can enable uniform dyeing of the entire textile fabric by measuring the number of revolutions of the textile fabric while using the existing dyeing processing facilities as it is.

In the above, embodiments of the present invention have been described with reference to the accompanying drawings, but those of ordinary skill in the art to which the present invention pertains can practice the present invention in other specific forms without changing its technical spirit or essential features. You can understand that there is Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
