[0019] The hybrid coating curing system (100) of the present invention will now be described in detail with reference to the accompanying Figures 1 to 7.

[0020] FIG. 1 is a diagram illustrating a hybrid coating curing system (100) according to one embodiment of the present invention.

[0021] Referring to FIG. 1, a hybrid coating curing system (100) according to one embodiment of the present invention may include a cleaner (110), a UV irradiator (120), a coating unit (130), a roll curing unit (140), a tenter (150), a punch (160), a dust collector (170), a folding machine (180), and a roller unit (190).

[0022] The cleaning machine (110) can remove foreign matter from the woven fabric web (w). Before being fed into the cleaning machine (110), the fabric web (w) can be fed through a J Box. The cleaning machine (110) will be described in more detail with reference to FIG. 2.

[0023] FIG. 2 illustrates a cleaner 110 according to one embodiment of the present invention.

[0024] Referring to Fig. 2, a cleaning machine (110) according to an embodiment of the present invention may include two brushes (111) spaced apart from each other by a preset distance. First, the two brushes (111) sweep up foreign matter, dust, etc. remaining on the fabric web (w), and then air is sucked in through an intake port (112) disposed between the two brushes (111) to remove the foreign matter, dust, etc. Also, the two brushes (111) may be of different types, as shown in Fig. 8. For example, the two brushes (111) are a combination of a primary brush (A) made of strong bristles to separate large particles such as pieces and debris of raw yarn pile, and a fiber-type secondary brush (B) to separate PM2.5. Depending on the state of adhesion of foreign matter to the fabric web (w), the primary brush, both the secondary brushes, or only the secondary brush can be selected for use. The shape of the primary brush with strong bristles can be selected from Channel spiral type, Punched roller type, Punched roller spiral type, Strip channel type, Twist brush single type, or Twist brush double type, and the secondary fiber-type roller brush can be selected from hook type brush, sponge type, embo type, Channel spiral type, Punched roller type, Punched roller spiral type, and Strip channel type.The material of the primary brush is selected from nylon, polypropylene, polyethylene, hog hair made of animal hog hair, horse hair made of horse hair, sheep wool made of sheep hair, antistatic bristles made of a mixture of nylon and carbon fiber, antistatic bristles made of a mixture of nylon and stainless steel, or antistatic bristles made of nylon pile bristles coated with an antistatic agent, and the material of the secondary brush is selected from polyester, PVA (Poly Vinyl Alcohol), nylon, polypropylene, polyethylene, antistatic bristles made of a mixture of nylon and carbon fiber, antistatic bristles made of a mixture of nylon and stainless steel, or antistatic bristles made of nylon pile bristles coated with an antistatic agent. The pile bristles of the primary brush have a diameter of about φ0.05 to 0.5 mm, and the pile bristles have a height of about 10 to 60 mm. The pile bristles of the secondary brush have a fineness of about 20 to 250 Denier based on the single yarn fineness, and the height of the fiber pile can be set to about 5 to 45 mm.

[0025] Referring again to Figure 1, the UV irradiator (120) can irradiate the fabric web (w) from which foreign objects have been removed with UV light. The UV irradiator (120) will be considered in more detail with reference to Figure 3.

[0026] FIG. 3 is a diagram illustrating a UV irradiator (120) according to one embodiment of the present invention.

[0027] Referring to FIG. 3, the UV irradiator (120) according to an embodiment of the present invention is installed in the form of a lamp above the advancing fabric web (w) to irradiate UV. The wavelength of the lamp is about 150 to 260 nm, preferably about 175 to 200 nm, and the height from the fabric web (w) to the lamp is about 70 to 370 mm. The height is adjusted according to the material, thickness, or process speed of the fabric web (w), and the fabric web (w) can be irradiated over the entire width of 1.0 to 5.0 m. By installing the UV irradiator (120), the bonding strength between the coating surface of the fabric web (w) and the coating agent can be strengthened. Also, the type of the lamp can be a mercury, ozone (O3), or LED lamp.

[0028] Referring again to FIG. 1, the coating unit (130) can apply a coating liquid (coating agent) to the UV-irradiated fabric web (w). The coating unit (130) can be installed in such a way that the coating agent transferred by a pump from a coating agent tank is sprayed through an upper coating nozzle (131) located above the fabric web (w) to apply it to the fabric web (w). In this case, when the fabric web (w) is a fabric having a relatively wide pile spacing of about 7 to 13 mm in the vertical direction, a line coating mold (132) can be used to coat only the woven pile rows. The upper coating nozzle (131) will be considered in more detail with reference to FIG. 9.

[0029] FIG. 9 illustrates an upper coating nozzle according to one embodiment of the present invention.

[0030] Referring to FIG. 9, the upper coating nozzle (131) according to one embodiment of the present invention moves a coating liquid hose (1312) having a coating liquid nozzle (1311) at one end thereof left and right using a linear drive unit (1313) and a plastic chain (1314) so ​​that the coating liquid is applied evenly and sufficiently over the entire width of the fabric web (w), and the precise amount of coating can be adjusted by adjusting the height difference between the doctor blade and the fabric web (w) so that only the set amount of coating can be applied.

[0031] The doctor blade may be made of stainless steel, tungsten, vanadium, molybdenum alloy steel, bronze, ceramic, or polyethylene, taking into consideration wear resistance, chemical resistance, oxidation resistance, solvent resistance, pH component influence, durability, damage to the fabric web (w), etc. In order to reduce damage to the fabric web (w) and achieve more uniform distribution of the coating agent application state, the doctor blade may be covered with a fiber material having a pile height of 5 mm or more, such as nylon, polyester, or polyethylene. The method of adjusting the application method and coating amount during top coating may be knife on roller type, knife on air type, or slot die type, as shown in FIG. 12. In addition, the line coating mold (132) may have rectangular holes (1321) arranged in series at a preset distance, as shown in FIG. 10. The material of the Line coating mold (132) may be selected from any one of stainless steel, tungsten, vanadium, molybdenum alloy steel, bronze, ceramic, polyethylene, and polypropylene, taking into consideration abrasion resistance, chemical resistance, oxidation resistance, solvent resistance, influence of PH components, damage to the raw web (w), etc. Also, FIG. 11 shows the raw web (w) coated with the Line coating mold (132).

[0032] Also, depending on the situation, a bottom coating method can be used. The roller coating machine used in the bottom coating method is composed of a coating liquid tank containing a coating liquid and a coating roller, and depending on the roller arrangement, a gravure type, kiss roller type, or reverse roller type can be used as shown in FIG. 13. Also, the polymer resin material of the coating liquid can include polyethylene (PE), polypropylene (PP), polyolefin (PO), polyester (PET), polyvinyl chloride (PVC), EVA (Ethylene Vinyl Acetate), or a blend resin made by mixing these, or a compound made by mixing these polymer resins with organic or inorganic compounds as functional additives. Also, the amount of coating agent applied to the fabric web (w) is selected according to the purpose of the finished product and the external environment in which the product will be used, and is 350 to 1,200 g / m by weight when the coating liquid is applied. 2 It can be set with.

[0033] The rolling hardening section 140 may roll and harden the fabric web w onto which the coating liquid has been sprayed. The rolling hardening section 140 may include a non-contact rolling machine 141, rolling rollers 142, and a hybrid hardening machine 143.

[0034] The non-contact rolling mill (141) is capable of injecting compressed air onto the coated dough web (w), said non-contact rolling mill (141) being considered in more detail with reference to FIG.

[0035] FIG. 4 is a diagram illustrating a non-contact rolling mill (141) according to one embodiment of the present invention.

[0036] Referring to FIG. 4, the non-contact rolling machine (141) according to an embodiment of the present invention is provided with a manifold (1411) above the advancing raw web (W) to inject compressed air (1412). The compressed air (1412) is provided dry and is uniformly injected over the entire width of the raw web (w) by a plurality of air injection nozzles attached to the manifold. The temperature of the compressed air may be set to about 3 to 40°C, and the wind speed may be set to about 10 to 50 m / sec. The height from the raw web (w) to the air injection nozzle is set to about 80 to 430 mm, and the height is adjusted according to the type of coating agent, temperature, coating amount, or process speed of the raw web (w) after coating. The material of the air injection nozzle may be stainless steel, copper, aluminum, ABS, nylon, PP, etc., and the nozzle may be circular or balanced in shape, but since uniform distribution is more effective than concentration of air pressure, it is preferable to select and use a flat type low noise nozzle. The non-contact rolling machine (141) is provided to allow the coating liquid to solidify and generate pressure at the same time.

[0037] The rolling roller (142) can roll the fabric web (w) more strongly when compressed air is injected into it. The rolling roller (142) will be described in more detail with reference to FIG.

[0038] FIG. 5 is a diagram illustrating a pressure roller (142) according to one embodiment of the present invention.

[0039] 5, the rolling roller (142) according to an embodiment of the present invention may be provided in a general plain type, a straight pattern type, an embossed pattern type, a wavy pattern type, etc. By providing the rolling roller (142), the coating agent can be more strongly bonded to the fabric web (w). The rolling roller (142) is made of polyvinylidene fluoride (PVDF) or polytetrafluoroethylene (PTFE) material for the purpose of achieving a bonding pressure between the coating agent and the fabric web (w) in a contact manner, and the pressure applied to the rolling roller may be in the range of 0.07 to 0.7 MPa.

[0040] The hybrid curing device (143) is capable of applying infrared and ultraviolet radiation to the rolled fabric web (w). The hybrid curing device (143) will be discussed in more detail with reference to FIG.

[0041] FIG. 6 illustrates a hybrid hardener (143) in accordance with one embodiment of the present invention.

[0042] Referring to FIG. 6, a hybrid curing device (143) according to an embodiment of the present invention may include a house (1431), an infrared lamp (1432), an ultraviolet lamp (1433), and a reflector (1434).

[0043] The house (1431) may be configured in the shape of a box with one side open.

[0044] The infrared lamp (1432) is connected to the inside of the house (1431) and can irradiate the fabric web (w) with infrared rays. The wavelength of the infrared lamp (1432) is in the far infrared (FIR) range of 50-900 μm, which is effective for a pattern with a bright color of the coating agent, and the wavelength of the mid infrared (MIR) range of 2-15 μm, which can be used universally regardless of color, and the height from the fabric web (w) to the lamp is about 70-370 mm, and the height is adjusted according to the type of coating agent, temperature, coating amount, or process speed of the fabric web (w) after coating, and the type of the lamp can be selected from LED, mercury, metal halide, and xenon lamps.

[0045] An ultraviolet lamp (1433) is coupled to the inside of the house (1431) and is capable of irradiating the fabric web (w) with ultraviolet light. The wavelength of the ultraviolet lamp (1433) will be discussed in more detail with reference to FIG.

[0046] FIG. 14 is a diagram showing the arrangement of ultraviolet lamps according to wavelengths according to an embodiment of the present invention.

[0047] 14, the wavelength of the ultraviolet lamp (1433) is 340-460nm, which is a short wavelength band (UVA), and the height from the fabric web (w) to the ultraviolet lamp (1433) is about 70-370mm, and the height is adjusted according to the type of coating agent, temperature, coating amount, or process speed of the fabric web (w) after coating, and the type of lamp can be selected from LED, mercury, metal halide, gallium, or xenon lamp. The arrangement of the ultraviolet lamp (1433) can be classified and combined according to the wavelength band, and the detailed format is wavelength A1 340-370nm, wavelength A2 371-400nm, wavelength A3 401-430nm, and wavelength A4 431-460nm, and only one wavelength A1 can be used, or two, three, or four can be used at the same time.

[0048] Referring again to FIG. 6, a reflector (1434) is attached to the inside of the house (1431) so that infrared and ultraviolet rays irradiated in other directions can be reflected by the fabric web (w).

[0049] The hybrid hardener (143) is provided to harden the coating agent and closely bond the internal structure of the polymer resin or compound coating agent.

[0050] Additionally, the hybrid curing device (143) may further include a temperature sensor (not shown).

[0051] A temperature sensor is provided at one fulcrum of the house (1431) and is capable of sensing the temperature of the fabric web (w).

[0052] Meanwhile, in order to maintain the reliability of the temperature sensor, the hybrid curing device 143 may further include a sensor monitoring unit (not shown) for determining whether the temperature sensor is broken.

[0053] The sensor monitoring unit (not shown) is configured to calculate an average error (A err ) is the preset limit error (S err ), it can be determined that the temperature sensor has failed.

[0054]

number

[0055] Here, A err is the average error, T aver is the overall average of the sensor values ​​of the temperature sensor, P aver is a partial average of n sensor values ​​of the temperature sensor, T σ means the overall standard deviation of the sensor values ​​of the temperature sensors. averis the overall average of the sensor value of the temperature sensor, and refers to a value obtained by calculating the overall average of the sensed temperature values ​​by collecting a large number of data during a preset period (e.g., one month) during which the temperature sensor operates normally, and Tσ refers to a value obtained by calculating the overall standard deviation of the sensed temperature values ​​by collecting a large number of data during the preset period (e.g., one month).

[0056] Also, P aver is a partial average of n sensor values ​​of the temperature sensor, and a preset number (n) of temperature values ​​are input in real time during the process of the temperature sensor being installed and used on-site, and the average of the preset number (n) of temperature values ​​is calculated. Since it corresponds to an average of some temperature values, it can be called a partial average.

[0057] In this case, if we use the partial average to calculate the estimated mean value with 95% confidence, the estimated mean value (μ) is JPEG2024545539000004.jpg would have a range of 1791.

[0058] Therefore, the upper or lower bound of the estimated mean (μ) and the overall mean (T aver ) and the average error (A err ) can be calculated as shown in [Equation 1] above.

[0059] Therefore, the average error (A err ) is the preset limit error (S err ) means that there is a very high possibility that the preset number (n) of temperature values ​​input in real time was input incorrectly due to a failure of the temperature sensor, so a sensor monitoring unit (not shown) can determine that the temperature sensor has failed when this condition is met.

[0060] Referring again to FIG. 1, the tenter (150) can move the set fabric web (w) at a preset speed.

[0061] Referring now to FIG. 7, the perforator (160) and dust collector (170) will be considered in more detail.

The punch (160) will be considered in more detail with reference to FIG. 15.

[0064] FIG. 15 is a diagram illustrating a perforator according to one embodiment of the present invention.

[0065] With reference to FIG. 15, the perforator (160) can include a mount that includes multiple perforation units.

[0066] Referring again to FIG. 1, the dust collector (170) can collect foreign matter from the fabric web (w) generated during the process of forming a number of drainage holes (h). The dust collector (170) can collect fine particles and odors generated through the perforator (160) through a dust collection hood, purify them through multi-stage filters having various materials and particle structure, and discharge them. More specifically, the foreign matter can be sucked into the collector in a vacuum manner using an air suction motor, purified through a filter, and discharged as clean air. The filter used here is made of a combination of polyester fiber, glass fiber, fine glass fiber, activated carbon fiber, etc., as shown in FIG. 16, and the filter mesh structure is divided into 3 to 100 μm and 2.5 μm or less in consideration of the size of particles to be passed through the filter, and the filter structure can be detachable for washing and cleaning.

[0067] The folding machine (180) can fold the fabric web (w) from which foreign objects have been removed. A width cutting machine (185) can be installed on one side of the folding machine (180). The width cutting machine (185) will be described in more detail with reference to FIG. 17.

[0068] FIG. 17 is a diagram illustrating a width cutting machine according to one embodiment of the present invention.

[0069] The width cutter (185) can be freely adjusted across the width of the fabric web (w) using a sliding assembly, and uses a rotating circular blade (cutting blade) rotated by a motor and can be covered with a safety cover to protect the operator from particle debris generated during cutting.

[0070] Referring again to FIG. 1, the roller unit (190) can keep the folded fabric web (w) in a constant folding direction while packaging it.

[0071] The roller unit (190) may include a tension roller (not shown) and a winding roller (not shown).

[0072] The tension roller can maintain the folding direction of the folded fabric web (w) in one (process progress) direction.

[0073] The winding roller can wind the fabric web (w) that has passed through the tension roller.

[0074] For reference, the transport speed of the fabric web (w) for completing the entire process of coating, curing and drying the fabric web (w) can reach about 1.5 to 4.5 meters / minutes, and the width of the fabric web (w) can be set to 1.0 to 5.0 meters.
