Description

Technical Field

[0001] The present invention relates to dyeing equipment, and particularly to dyeing equipment for an anhydrous dyeing system.

Background Art

[0002] In the anhydrous dyeing technology of polyester fibers described in Patent Document 1, after putting the pulverized dye into the dye tank, the dyeing agent in the dye tank is injected into a digital printing machine in the dyeing apparatus by a pressure pump, and it is disclosed that printing is performed by injecting it onto a fabric placed horizontally with the nozzles in the digital printing machine. However, in this case, since it is necessary to adjust the color of the dye in advance and then inject it into the dye tank, the color cannot be adjusted in real time.

[0003] Regarding dyeing equipment for dyeing yarns, for example, it is configured to have a plurality of dye tanks each containing dyes of specific colors (for example, the three primary colors), a dye mixing tank, a dye output device, pipes arranged between each dye tank and the dye mixing tank, and between the dye mixing tank and the dye output device, and pumps arranged on each pipe.

[0004] With this configuration, by controlling the ratio of the dyes of specific colors stored in the dye tanks output to the dye mixing tank by each pump, after mixing into the mixed dye of the color to be dyed in the dye mixing tank, it can be output to the dye output device and the yarn can be dyed in the color to be dyed.

[0005] However, for example, when the lengths of the respective pipes are different, the ratio of the dyes of each color output to the dye mixing tank cannot be accurately controlled by the pressure control by the pump, and there is a possibility that the mixed dye of the color to be dyed cannot be obtained, so there is still room for improvement.

[0007] Therefore, the present invention aims to provide a dyeing equipment for an anhydrous dyeing system that improves upon at least one drawback of the prior art. [Means for solving the problem]

[0008] To achieve the above objective, the present invention is a dyeing apparatus for an anhydrous dyeing system used to output dye to a material to be dyed, A dye supply means comprising at least two dye supply means, each having a dye storage can for containing dye and a dye supply guide pipe connected to the dye storage can, Each of the dye supply means has a dye mixing box connected downstream of the dye supply guide pipe, A dye injection means having at least one dye output guide tube connected downstream of the dye mixing box and at least one flow path connected to the dye output guide tube and used to output dye to the object to be dyed, The present invention provides a dyeing apparatus for an anhydrous dyeing system, comprising at least two pumping means arranged in each of the dye supply guide tubes, each of which is configured to have an input pump configured to have an adjustable flow rate along the direction in which the dye is supplied, a temporary storage case connected to the input pump, and an output pump connected to the temporary storage case and configured to have an adjustable flow rate. [Effects of the Invention]

[0009] The dyeing equipment of the anhydrous dyeing system of the present invention temporarily stores some of the dye in a temporary storage case and manages the water level of the dye in the temporary storage case. This makes it possible to accurately control the pressure and flow rate of the dye output from the temporary storage case to the dye mixing box or each passage, even when the pressure of the dye in the dye supply means or dye mixing box changes and the lengths of the pipes of each dye supply guide tube and each dye output guide tube are different. This improves the degree of dye mixing, the accuracy and quality of yarn dyeing, and maintains the amount of dye absorbed by the yarn to be dyed at saturation absorption, while preventing excessive or insufficient absorption of dye by the yarn, thereby improving the dyeing quality of the yarn.

[Figure 7] This is a schematic diagram of the lower base, upper base, and each dye injection module in the second embodiment, shown from a different angle. [Modes for carrying out the invention]

[0011] The present invention will be described in detail below with reference to the attached drawings and examples.

[0012] As shown in Figures 1 to 3, the first embodiment of the dyeing equipment for the anhydrous dyeing system of the present invention is for outputting dye to a dyeing target 8 consisting of multiple yarns 81 made of, for example, polyester, nylon, TPU, TPEE, cotton, polypropylene, or acrylic. This anhydrous dyeing system is configured to include multiple dye supply means 1, a dye mixing box 2, a stirring means 3, a temperature control means 4, a dye injection means 5, multiple pump means 6, and a control means 7.

[0013] Each dye supply means 1 is used to output dyes of different colors to the dye mixing box 2. Each dye supply means 1 includes a dye storage can 11 used for storing dyes and a dye supply guide pipe 12 connected between the dye storage can 11 and the dye mixing box 2. In this embodiment, there are five dye storage cans 11, four of which are used to store four dyes (CMYK): cyan, magenta, yellow, and black, and the other one is used to store a transparent (or colorless) dye. In this invention, the number of dye storage cans 11 is not limited; for example, three cans can be installed and used to store three dyes (RGB): red, green, and blue.

[0014] The dye mixing box 2 is located downstream of the dye supply means 1 (in the dye supply path). By connecting the dye mixing box 2 to each dye supply guide tube 12, the dyes from each dye storage can 11 are mixed in the dye mixing box 2 to form a mixed dye of the color to be used to dye the object to be dyed 8.

[0015] The stirring means 3 is located in the dye mixing box 2 and is used to stir and mix the dyes that are output from each dye storage can 11 to the dye mixing box 2. Specifically, the stirring means 3 in this embodiment includes an impeller 31 that is rotatably located inside the dye mixing box 2 and used for stirring the dyes, and a motor 32 that is located in the dye mixing box 2 and used to drive the impeller 31.

[0016] The temperature control means 4 is disposed in the dye mixing tank 2 and includes a heater 41 used for heating the dye in the dye mixing tank 2 and a temperature sensor 42 disposed in the dye mixing tank 2 and used for detecting the temperature of the dye in the dye mixing tank 2. Incidentally, an electric heating tube or an electric heating plate can be used as the heater 41.

[0017] As shown in FIGS. 1, 2, and 4, the dye injection means 5 is located downstream of the dye mixing tank 2 (in the dye supply path). The dye injection means 5 includes a lower pedestal 51, an upper pedestal 52 disposed above the lower pedestal 51 in the vertical direction Z, a plurality of dye output guide tubes 54 disposed in the dye mixing tank 2, a plurality of nozzle devices 55 disposed between the lower pedestal 51 and the upper pedestal 52 so as to be connected to each dye output guide tube 54, a plurality of dye discharge guide tubes 56 (only one is shown in FIG. 1 due to the drawing angle) disposed in the lower pedestal 51, and a suction device 57 communicating with each dye discharge guide tube 56. In this embodiment, different types of pumps can be used as the suction device 57.

[0018] As shown in FIGS. 2, 4, and 5, the lower pedestal 51 includes a first inner surface 511 facing the upper pedestal 52 side along the vertical direction Z, a first outer surface 512 on the opposite side of the first inner surface 511 along the vertical direction Z, a plurality of lower grooves 513 formed in the first inner surface 511, a plurality of first downstream paths 514 each extending from the first outer surface 512 to each lower groove 5

[0019] The upper pedestal 52 has a second inner surface 521 that abuts against the first inner surface 511, a second outer surface 522 on the opposite side of the second inner surface 521 in the vertical direction Z, a plurality of upper grooves 523 formed in the second inner surface 521, a plurality of first upstream channels 524 each extending from the second outer surface 522 to each upper groove 523, and a plurality of second upstream channels 525 each extending from the second outer surface 522 to each upper groove 523. Each upper groove 523 extends along the first horizontal direction X and is arranged with a space therebetween in the second horizontal direction Y. Each upper groove 523 is connected to a corresponding lower groove 513 to constitute one passage 53. Each of the first upstream channels 524 and the second upstream channels 525 extends along the vertical direction Z. Each first upstream channel 524 faces a corresponding first downstream channel 514, and each second upstream channel 525 faces a corresponding second downstream channel 515.

[0020] Each nozzle device 55 is provided so as to correspond to each of the first upstream channels 524, the second upstream channels 525, the first downstream channels 514, and the second downstream channels 515. Each nozzle device 55 has a connection portion 551 that communicates with a corresponding dye output guide tube 54 on the side away from the corresponding passage 53, and a nozzle head 552 that extends from the connection portion 551 to the corresponding passage 53. Each connection portion 551 is mounted on a corresponding flow path (the first upstream channel 524 or the second upstream channel 525 or the first downstream channel 514 or the second downstream channel 515) by a thread (not shown) formed on its outer side. Each nozzle head 552 outputs the dye from the dye output guide tube 54 connected to the corresponding connection portion 551 to the corresponding passage 53 by communicating with the corresponding connection portion 551.

[0021] It should be noted that the specific configuration of each nozzle device 55 is not limited to this example, and it is also possible to use different types of dye injection structures. For example, the nozzle device 55 may be a spray nozzle, a thermal transfer type, or a direct dye jet type nozzle head.

[0022] As shown in Figures 1, 2, and 5, each passage 53 is used for the yarn 81 to be dyed to pass through. The dye injection means 5 uses each first upper passage 524, each second upper passage 525, each first lower passage 514, and each second lower passage 515 to output the mixed dye mixed in the dye mixing box 2 to the yarn 81 passing through the passage 53.

[0023] Each dye discharge guide tube 56 is connected to each dye discharge channel 516, and the suction device 57 sucks up and discharges excess dye from within each passage 53 via each dye discharge channel 516 and each dye discharge guide tube 56.

[0024] Each pumping device 6 is positioned in each dye supply guide tube 12 and each dye output guide tube 54, respectively. In each dye supply guide tube 12, a pumping device 6 corresponding to a position close to the dye mixing box 2 is positioned, and in each dye output guide tube 54, a pumping device 6 corresponding to a position close to the corresponding first upper passage 524 or second upper passage 525 or first lower passage 514 or second lower passage 515 is positioned.

[0025] Each pumping device 6 includes an input pump 61 configured to have an adjustable flow rate, a temporary storage case 62 made of a light-permeable material that contains the dye, a scale 63 placed in the temporary storage case 62, a water level meter 64 placed in the temporary storage case 62 and used to detect the dye level of the dye within the temporary storage case 62, and an output pump 65 configured to have an adjustable flow rate. The input pump 61, the temporary storage case 62, and the output pump 65 are arranged sequentially in a holding frame (not shown) along the dye supply path. In this embodiment, precision micro-liquid pumps are used as each input pump 61 and each output pump 65, but in the present invention, tube pumps, gear pumps, screw pumps, servo pumps, or piezo pumps may also be used.

[0026] Each temporary storage case 62 located upstream of the dye mixing box 2 is at the same height, and each temporary storage case 62 located upstream of each first upper channel 524 and second upper channel 525 is at the same height, and furthermore, each temporary storage case 62 located upstream of each first lower channel 514 and second lower channel 515 is at the same height.

[0027] As shown in Figures 2 and 3, the control means 7 is electrically connected to each input pump 61, each output pump 65, each water level meter 64, and the temperature sensor 42. In this embodiment, a programmable logic controller (PLC) is used as the control means 7. As a result, the control means 7 maintains the dye level of the dye in the corresponding temporary storage case 62 at a target level by controlling the flow rate of the corresponding input pump 61 and / or output pump 65 based on the dye level of the dye detected by each water level meter 64. Alternatively, the user can manually adjust the flow rate of the corresponding input pump 61 and the corresponding output pump 65 by visually checking the corresponding scale 63, thereby maintaining the dye level of the dye in the corresponding temporary storage case 62 within a predetermined range.

[0028] Furthermore, the control means 7 can improve the efficiency and uniformity of dyeing by controlling the heater 41 to heat the dye in the dye mixing box 2 to a target temperature value based on the temperature of the dye detected by the temperature sensor 42. For example, with nylon fibers, dye adsorption begins when the dye temperature reaches 40°C, and the dyeing rate increases as the temperature rises thereafter. When the dye temperature reaches 100°C, the dye transfer is almost complete, so controlling it in this way improves the uniformity of dyeing.

[0029] The following will explain in detail the process by which the dyeing equipment of the anhydrous dyeing system of the present invention mixes dyes and outputs them to each yarn 81, with reference to Figures 2, 3, and 5.

[0030] First, in step S1, a CMYK color model value is obtained that represents the proportion of the four CMYK dyes corresponding to the color to be dyed. This can be done using commercially available software such as Photoshop®.

[0031] Next, in step S2, for test staining, dye from one of the dye storage cans 11 is poured into the dye mixing box 2.

[0032] In step S3, one of the passages 53 is defined as test passage 53' (see Figure 5), the first upper passage 524 corresponding to test passage 53' is defined as the first test passage 524', the pump means 6 corresponding to the first test passage 524' is defined as the first test pump means 6', the temporary storage cases 62 containing CMYK color dyes are defined as opaque dye temporary storage cases 62', and the temporary storage case 62 containing transparent dyes is defined as transparent dye temporary storage case 62''.

[0033] In step S4, the yarn 81 to be tested for dyeing is passed through the test passage 53' defined in step S3 at a predetermined yarn supply speed.

[0034] In step S5, the input pump 61 and output pump 65 of the first test pump means 6' defined in step S3 are opened and adjusted to maintain the dye level in the temporary storage case 62 of the first test pump means 6' at the target level, and to uniformly dye the yarn 81 to be dyed by allowing the amount of dye adsorbed to reach the saturation adsorption amount. At this time, the flow rate of the output pump 65 of the first test pump means 6' is defined as the test output flow rate. The saturation adsorption amount represents the maximum amount of dye that a predetermined unit length of the yarn 81 to be dyed can absorb. If the amount of dye adsorbed onto the yarn 81 to be dyed for testing falls below the saturation absorption limit, discontinuous dyeing will occur on the yarn 81. If the amount of dye adsorbed onto the yarn 81 exceeds the saturation absorption limit, the dye will seep out and spill onto the yarn 81. Therefore, if the amount of dye adsorbed onto the yarn 81 is neither too little nor too much, it can be determined that the dye adsorbed onto the yarn 81 has reached its saturation absorption limit. Since the saturation absorption limit of the yarn 81 varies depending on various factors such as thickness, material, and humidity, the saturation absorption limit of the yarn 81 can be reliably obtained through the above process. The dye flow rate that needs to be supplied to the target yarn 81 can be obtained under a specific feed rate.

[0035] In step S6, the input pump 61 and output pump 65 corresponding to the transparent dye temporary storage case 62" are opened to wash out the dyes that were in each dye supply guide tube 12, the dye mixing box 2, and each dye output guide tube 54. Then, the output pump 65 of the first test pump means 6' is opened to output transparent dye to the yarn 81 to be dyed until it is confirmed that all the dye adsorbed on the yarn 81 in step S5 has been washed off.

[0036] In step S7, each input pump 61 and each output pump 65 in each dye output guide tube 54 are closed. Then, based on the acquired CMYK color model values, each output pump 65 and each input pump 61 corresponding to each opaque dye temporary storage case 62' are opened and adjusted to maintain the dye in each opaque dye temporary storage case 62' at the target water level, while the dyes of each color are injected into the dye mixing box 2 in proportions corresponding to the CMYK color model values ​​and mixed.

[0037] In step S8, the output pump 65 and input pump 61 corresponding to the transparent dye temporary storage case 62" are opened and adjusted to maintain the dye in the transparent dye temporary storage case 62" at the target water level, while confirming that the color intensity of the dye in the dye mixing box 2 matches the color to be dyed. At the same time, the flow rates of each output pump 65 corresponding to each non-transparent dye temporary storage case 62' and transparent dye temporary storage case 62" are defined as the dye mixing flow rates, and the test dyeing is completed.

[0038] In this way, the parameters for each target water level, test output flow rate, and each dye mixing flow rate are obtained through the test staining from step S2 to step S8 and stored in the control means 7.

[0039] In step S9, each input pump 61 and each output pump 65 in each dye supply guide tube 12 are closed. Multiple yarns 81 are passed through each passage 53 at the yarn supply speed. The dye injection means 5 sets the flow path (first upper flow path 524, second upper flow path 525, first lower flow path 514 or second lower flow path 515) through which the dye is output. Based on the saturation absorption amount, the control means 7 supplies dye from the dye mixing box 2 to the corresponding flow path and dyes each yarn 81 through each passage 53. Just before the dye in the dye mixing box 2 runs out, each input pump 61 and each output pump 65 in each dye output guide tube 54 are closed and the process returns to step S8, where each input pump 61 and each output pump 65 in each dye supply guide tube 12 are opened and the dye mixing is performed again.

[0040] For each passage 53, the user can either select the corresponding first upper passage 524 and first lower passage 514 to output the dye and perform dyeing, or further select the corresponding second upper passage 525 and second lower passage 515 to output the dye through a total of four passages, thereby obtaining a more complete and uniform dyeing effect. Note that even if the number of selected passages differs, the saturation absorption amount that the yarn 81 can absorb remains the same, so the total flow rate of dye output from each passage must match the test output flow rate.

[0041] Another variation of this embodiment is that, in defining lower and upper limits for the dye water level of the dye in each temporary storage case 62, the control means 7 can be instructed to control the dye water level of the dye in each temporary storage case 62 so that it is maintained between the corresponding lower and upper limits.

[0042] Maintaining the dye in the temporary storage case 62 within the water level range determined by the lower and upper limits means that the pressure of the dye output from the temporary storage case 62 to the corresponding output pump 65 is maintained within a certain range. This allows the dye output from the temporary storage case 62 to maintain a constant pressure, ensuring that the flow rate of dye output from each output pump 65 is accurate and stable, and reducing pressure-related errors during dye supply.

[0043] Therefore, by accurately and stably maintaining the flow rate of dye output by each pump means 6, the flow rate and ratio of dye output to the dye mixing box 2 can be precisely controlled. This ensures that the dyes of each color are mixed in proportions corresponding to the CMYK color model values, and the amount of dye output to each yarn 81 is controlled to maintain each yarn 81 in a state of just saturation absorption, thereby improving the quality of dyeing.

[0044] It should be noted that by changing the configuration of the dye injection means 5, the dyeing equipment of the anhydrous dyeing system of the present invention can be applied to different types of objects to be dyed, that is, accurate color mixing and flow rate control can be achieved in the same way as with the dyeing equipment of the anhydrous dyeing system of the present invention.

[0045] Figures 6 and 7 show a second embodiment of the dyeing equipment for the anhydrous dyeing system of the present invention. Referring also to Figure 5, the difference between this second embodiment and the first embodiment is that in this second embodiment, two first mounting grooves 517 are formed on the first outer surface 512 of the lower base 51, and two second mounting grooves 526 are formed on the second outer surface 522 of the upper base 52. Furthermore, the dye injection means 5 in this second embodiment does not have a dye output guide tube 54 and a pump means 6 arranged in the dye output guide tube. Instead, the dye injection means 5 in this second embodiment has four dye injection modules 58 arranged in each of the first mounting grooves 517 and each of the second mounting grooves 526, a supply module 59 arranged between each dye injection module 58 and the dye mixing box 2, and a piezoelectric switch module (not shown) arranged in each dye injection module 58. Each dye injection module 58 has multiple dye injection channels 581 that communicate with the passage 53. In this second embodiment, by controlling the piezoelectric switch module, the dye in the dye mixing box 2 can be output to the yarn 81 in each passage 53 via the supply module 59 and each dye injection channel 581.

[0046] The dyeing equipment for the anhydrous dyeing system of the present invention has the following advantages.

[0047] First, by temporarily storing some of the dye in the temporary storage case 62 and managing the water level of the dye in the temporary storage case 62, even when the pressure of the dye in the dye supply means 1 or the dye mixing box 2 changes and the lengths of the pipes of each dye supply guide tube 12 and each dye output guide tube 54 are different, it becomes possible to accurately control the pressure and flow rate of the dye output from the temporary storage case 62 to the dye mixing box 2 or each passage 53. This improves the degree of dye mixing and the dyeing accuracy and quality of each yarn 81, as well as maintaining the amount of dye absorbed by the yarn 81 to be dyed at saturation absorption, and preventing excessive or insufficient absorption of dye by the yarn 81, thereby improving the dyeing quality of the yarn 81.

[0048] Furthermore, by arranging each temporary storage case 62 upstream of the dye mixing box 2 at the same height, and arranging each temporary storage case 62 upstream of each first upper channel 524 and second upper channel 525 at the same height, and further arranging each temporary storage case 62 upstream of each first lower channel 514 and second lower channel 515 at the same height, the water level adjustment by each pump means 6 becomes more effective, and in particular, the influence of water pressure due to the height at which each temporary storage case 62 is arranged can be eliminated, so that the flow rate of dye to the first lower channel 514 and the second lower channel 515 can be controlled stably and accurately, and deviations become less likely.

[0049] Furthermore, by injecting dye from nozzle devices 55 located above and below the yarn 81 while it is passing through the passages 53 defined between the lower base 51 and the upper base 52, the effects of the yarn 81's movement are suppressed, and since the dyeing is carried out by immersing the yarn in the dye within the sealed space of the passages 53, the efficiency of dye absorption by the yarn 81 is increased, and dye can also be saved.

[0050] Furthermore, since the first upper channel 524, the second upper channel 525, the first lower channel 514, and the second lower channel 515 are all configured to extend along the vertical direction Z, the dye can be supplied to each passage 53 via the shortest route through each nozzle device 55, thereby increasing the efficiency of dye supply.

[0051] Furthermore, by configuring each dye discharge channel 516, excess dye in each passage 53 can be discharged, thus avoiding a situation where an excessive amount of dye is supplied to the yarn 81.

[0052] Although embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications are possible without departing from its essence. [Explanation of Symbols]
