Description

Technical Field

[0001] The present invention relates to the technical field of fabric processing, and specifically to a flat fabric transmission structure in automated garment manufacturing based on visual analysis. Background Art

[0002] With the continuous progress of technology, the garment industry is gradually developing towards automation and intelligence. Automated garment production lines can improve production efficiency, reduce labor costs, and ensure the consistency of product quality. Therefore, they are increasingly widely used in garment enterprises. In the process of automated garment manufacturing, the transmission of fabric is a key link, directly affecting the smoothness of the entire production process and the quality of the product.

[0003] On traditional garment production lines, fabrics are usually transmitted through simple rollers or conveyor belts. However, this transmission method is prone to causing wrinkles in the fabric, especially for some thin, light, and soft fabrics, the wrinkle problem is more serious. Wrinkles not only affect the subsequent processing of the fabric, such as the accuracy of processes like cutting and sewing, but may also lead to quality defects in the final product. Summary of the Invention

[0004] The purpose of the present invention is to provide a flat fabric transmission structure in automated garment manufacturing based on visual analysis to solve the problems raised.

[0005] To achieve the above objective, the present invention provides the following technical solution: A flat fabric transmission structure in automated garment manufacturing based on visual analysis, including a conveying frame. On both sides of the conveying frame, side brackets are symmetrically arranged. At the bottom of the side brackets, there is a bottom bracket connected to the bottom of the conveying frame. At the center of the top of the bottom bracket, there is a lower smoothing plate embedded in the middle frame body of the conveying frame. A water storage chamber is arranged at the bottom of the lower smoothing plate;

[0006] On the top of the conveying frame, there is a flattening frame sleeved on the top of the side brackets. At the center of the top of the flattening frame, a circulating fan is fixedly arranged. At both ends of the bottom of the flattening frame, there are limiting frames slidably sleeved. At the bottom of the flattening frame, there is an upper smoothing plate facing the lower smoothing plate;

[0007] On the outer wall of the side bracket, a control panel is embedded. Inside the control panel, there is a fabric parameter acquisition module for acquiring the fabric parameters of the fabric moving along the top of the conveying frame. The fabric parameter acquisition module is communicatively connected to a fabric parameter analysis module for real-time analysis of the acquired fabric parameters. The fabric parameter analysis module sends the generated results to a fabric transportation control terminal, and the fabric transportation control terminal makes targeted adjustment and processing of the flat fabric transmission structure for automated garment manufacturing according to the received results.

[0008] Further, a number of groups of lifting cylinders are symmetrically arranged on the inner walls of both sides of the conveying frame. A conveying traction roller is arranged between several groups of the same-side lifting cylinders. A suction frame near both ends of the lower screed plate is arranged on the top of the conveying frame. A hole adapted to the lower screed plate is penetratingly arranged in the middle of the conveying frame.

[0009] Further, jacking cylinders sleeved on the bottom of the lower screed plate are symmetrically arranged at the four corners of the top of the bottom bracket. A number of groups of connecting hoses connecting the lower screed plate with the water storage bin are arranged at the bottom of the lower screed plate.

[0010] Further, a heater is nested inside the lower screed plate. A number of groups of air dispersion holes one connecting the heater are penetratingly arranged on the top of the lower screed plate.

[0011] Further, a number of groups of splicing valves arranged around the outer periphery of the circulating fan are arranged on the top of the leveling frame. Pipe fittings are connected between several groups of the splicing valves. A branch pipe is connected between the pipe fittings and the circulating fan. Fixed flanges connected to the bottoms of the splicing valves are arranged at the four corners of the top of the upper screed plate. A number of groups of return air holes are symmetrically arranged on the inner walls of both sides of the leveling frame on both sides of the upper screed plate. Air dispersion holes two are arranged on the bottom surface of the upper screed plate. A heater is embedded inside the upper screed plate.

[0012] Further, lifting cylinders are symmetrically sleeved and embedded at both ends of the leveling frame. The limiting frame is clamped on the top of the lifting cylinders. A movable plate facing the conveying frame is arranged at the bottom of the end face of the limiting frame.

[0013] Further, the fabric parameter acquisition module includes a visual acquisition unit and a tension sensing unit; the visual acquisition unit is used to acquire the ratio S / A of the wrinkled area on the fabric surface and the lateral offset distance d, and the tension sensing unit is used to acquire the real-time fabric tension value T, where S represents the wrinkled pixel area within the detection area, A represents the total area of the detection area, d represents the lateral distance between the fabric edge and the reference line of the conveying frame, and T represents the measured value of the tension sensor.

[0014] Further, the process of the fabric parameter analysis module analyzing the multiple parameters collected by the fabric parameter acquisition module one by one is as follows:

[0015] The flatness coefficient y = 1 - S / A. The preset flatness threshold y0 is retrieved from the inside of the control panel. When y < y0, it is determined that there is a risk of fabric wrinkles, and a wrinkle processing signal is generated;

[0016] The tension deviation ΔT = |T - T0|. The preset tension deviation threshold ΔT0 is retrieved from the inside of the control panel. When ΔT > ΔT0, it is determined that the fabric tension is abnormal, and a tension adjustment signal is generated;

[0017] Retrieve the preset allowable offset threshold d0 from inside the control panel and compare it with the lateral offset distance d for analysis. When d > d0, it is determined that the fabric position offset exceeds the limit, and a position correction signal is generated.

[0018] The fabric parameter analysis module generates three types of signals based on the above results: a wrinkle treatment signal, a tension adjustment signal, and a position correction signal, and sends them to the fabric transportation control terminal.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. In the fabric conveying stage of the present invention, the conveying and traction rollers on the conveying frame can be adjusted to be arranged in a vertically staggered manner through a lifting cylinder, and cooperate with the equipment in the processing area to achieve smooth pulling of the fabric, ensuring the flatness of the fabric. When the fabric is leveled, the circulating fan extracts external air, filters it through a filter element, and then transports it to the upper and lower leveling plates, while recycling the hot air, which not only ensures air cleanliness but also saves energy.

[0021] 2. In the present invention, the heaters in the upper and lower leveling plates cooperate with the air transported by the circulating fan to heat and iron the fabric, and the lower leveling plate can mix atomized clear water with air, heat it, and then spray it onto the fabric to enhance the ironing effect. In addition, the return air holes extract the overflowing hot mixed liquid mist for reuse, reducing the energy consumption of subsequent leveling. Description of the Drawings

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1: Please refer to Figure 1 - Figure 7 As shown, this embodiment is a flat cloth transmission structure in automated garment manufacturing based on visual analysis, including a conveying frame ①. Side brackets ② are symmetrically arranged on both sides of the conveying frame ①. A bottom bracket ③ connected to the bottom of the conveying frame ① is arranged at the bottom of the side bracket ②. A lower leveling plate 304 embedded in the middle frame body of the conveying frame ① is arranged at the center of the top of the bottom bracket ③. A water storage bin 301 is arranged at the bottom of the lower leveling plate 304;

[0033] A leveling frame ④ sleeved on the top of the side bracket ② is arranged at the top of the conveying frame ①. A circulation fan ⑤ is fixedly arranged at the center of the top of the leveling frame ④. Limiting frames ⑥ are slidably sleeved at the bottom ends of both ends of the leveling frame ④. An upper leveling plate 403 facing the lower leveling plate 304 is arranged at the bottom of the leveling frame ④.

[0034] The cloth for garment processing is transported by the conveying frame ① to the processing area. Several groups of conveying traction rollers 102 on the conveying frame ① are adjusted by the lifting cylinders 101, so that several groups of conveying traction rollers 102 are arranged in a vertically staggered manner, and the cloth passing through the surface thereof is subjected to staggered traction and pulling treatment, and is combined with the cloth traction equipment in the processing area to operate in coordination, so that the cloth is subjected to flat pulling treatment.

[0035] Several groups of lifting cylinders 101 are symmetrically arranged on the inner walls on both sides of the conveying frame ①. Conveying traction rollers 102 are arranged between several groups of same-side lifting cylinders 101. A suction frame 103 close to both ends of the lower leveling plate 304 is arranged at the top of the conveying frame ①. A hole adapted to the lower leveling plate 304 is arranged through the middle of the conveying frame ①.

[0036] The excess hot mixed liquid mist overflows outward along the gap between the lower smoothing plate 304 and the upper smoothing plate 403. Under the continuous extraction of the return air hole 405 by the circulating fan 5, the air between the outer peripheries of the upper smoothing plate 403 and the lower smoothing plate 304 is continuously extracted under negative pressure. Accordingly, the hot mixed liquid mist is effectively extracted and reused, reducing the subsequent continuous leveling energy consumption.

[0037] At the four corners of the top of the bottom bracket 3, lifting cylinders 302 sleeved on the bottom of the lower smoothing plate 304 are symmetrically arranged, and a plurality of groups of connecting hoses 305 connected to the water storage tank 301 are arranged at the bottom of the lower smoothing plate 304.

[0038] The bottom bracket 3 drives the lower smoothing plate 304 to slide upward through the lifting cylinder 302. The lower smoothing plate 304 contacts the bottom of the fabric, and cooperates with the upper smoothing plate 403 to contact the fabric up and down, prompting the fabric to move and transport within the limiting space. And the circulating fan 5 transports and guides part of the air into the lower smoothing plate 304, and the air is heated by the heater 303 inside the lower smoothing plate 304;

[0039] At the same time, an atomizer and a water pump are arranged inside the water storage tank 301, which are used to extract part of the clear water, atomize it and then mix the air to move and transport it into the first air dispersion hole 306, obtaining a mixed liquid mist. The heater 303 heats the passing mixed liquid mist to obtain a hot mixed liquid mist. The hot mixed liquid mist is sprayed along the first air dispersion hole 306 to contact the fabric, and within the narrow gap between the lower smoothing plate 304 and the upper smoothing plate 403, the fabric is quickly ironed.

[0040] The heater 303 is nested inside the lower smoothing plate 304, and a plurality of groups of first air dispersion holes 306 connecting the heater 303 are arranged through the top of the lower smoothing plate 304; a plurality of groups of splicing valves 401 arranged around the outer periphery of the circulating fan 5 are arranged at the top of the leveling frame 4. Pipe fittings are connected between the plurality of groups of splicing valves 401, and a branch pipe is connected between the pipe fittings and the circulating fan 5. Fixed flanges connected to the bottom of the splicing valve 401 are arranged at the four corners of the top of the upper smoothing plate 403. A plurality of groups of return air holes 405 are symmetrically arranged on the inner walls of both sides of the leveling frame 4 on both sides of the upper smoothing plate 403. A second air dispersion hole 404 is arranged on the bottom surface of the upper smoothing plate 403, and the heater 303 is embedded inside the upper smoothing plate 403.

[0041] When the fabric passes through the leveling frame 4 along the conveying rack 1, the circulating fan 5 extracts external air. An air filter element is arranged on the outer periphery of the bottom of the circulating fan 5, which is used to filter the extracted external air. The extracted and purified air is transported to the upper smoothing plate 403 and the lower smoothing plate 304 through pipe fittings and branch pipes. At the same time, the circulating fan 5 is connected to the suction rack 103 and the return air hole 405 through pipe fittings, which is used to recycle the used hot air, and the recycled air is also subjected to secondary treatment by the air filter element.

[0042] When waiting for the fabric to pass through the area between the leveling frame 4 and the bottom bracket 3, at the bottom of several groups of splicing valves 401 on the leveling frame 4, there are downward pressing cylinders connected to the upper wiping plate 403. The downward pressing cylinders drive the upper wiping plate 403 to slide down close to the fabric. The internal heater 303 of the upper wiping plate 403 operates to heat the bottom plate of the lower wiping plate 304. At the same time, the splicing valve 401 guides the air pipe inside the circulating fan 5 to the inside of several groups of air dispersion holes two 404 of the upper wiping plate 403. During the air flowing inside the upper wiping plate 403 and dispersing to the inside of several groups of air dispersion holes two 404, the air is heated by the heater 303, prompting the air dispersion holes two 404 to guide the hot air to spray on the fabric surface.

[0043] At both ends of the leveling frame 4, lifting cylinders 402 are symmetrically sleeved and embedded. The limiting frame 6 is clamped on the top of the lifting cylinders 402, and at the bottom of the end face of the limiting frame 6, there is a movable plate 601 facing the conveying rack 1.

[0044] Embodiment 2: This embodiment is a leveling fabric transmission structure in automated garment making based on visual analysis, including a control panel embedded on the outer wall of the side bracket 2. Inside the control panel, there is a fabric parameter acquisition module for acquiring the fabric parameters during the movement of the fabric along the top of the conveying rack 1. The fabric parameter acquisition module is communicatively connected to a fabric parameter analysis module for real-time analysis of the acquired fabric parameters. The fabric parameter analysis module sends the generated results to the fabric transportation control terminal, and the fabric transportation control terminal makes targeted adjustment and processing of the automated garment making leveling fabric transmission structure according to the received results.

[0045] The fabric parameter acquisition module includes a visual acquisition unit and a tension sensing unit. The visual acquisition unit is installed on the outer wall of the leveling frame 4 near the feeding end of the conveying rack 1, and the tension sensing unit is installed on the shafts of several groups of conveying and traction rollers 102;

[0046] The visual acquisition unit is used to obtain the ratio S / A of the wrinkled area on the fabric surface and the lateral offset distance d. S represents the area of the fabric wrinkled area extracted by the visual sensor pixel recognition algorithm, A represents the fixed total area of the visual detection area, and d represents the lateral distance between the fabric edge and the reference line of the conveying rack;

[0047] The tension sensing unit is used to obtain the real-time fabric tension value T, where T represents the fabric tension value collected by the tension sensor in real time.

[0048] The process of the fabric parameter analysis module analyzing each of the multiple parameters collected by the fabric parameter acquisition module is as follows:

[0049] The flatness coefficient y = 1 - S / A. Retrieve the preset flatness threshold y0 from inside the control panel. Here, y represents the quantitative index of the fabric flatness, with a value range of [0, 1]. The larger the value, the higher the flatness; y0 represents the threshold for determining qualified in the preset flatness, simply referred to as the preset flatness threshold. For example, y0 = 0.95, which can be dynamically adjusted according to the fabric type.

[0050] When y < y0, it is determined that there is a risk of fabric wrinkles, and a wrinkle treatment signal is generated.

[0051] The tension deviation ΔT = |T - T0|. Retrieve the preset tension deviation threshold ΔT0 from inside the control panel. T0 represents the standard tension value preset for the current fabric material, ΔT represents the absolute value deviation of the actual tension from the standard tension, and ΔT0 represents the maximum allowable tension deviation threshold, which is called the preset tension deviation threshold.

[0052] When ΔT > ΔT0, it is determined that the fabric tension is abnormal, and a tension adjustment signal is generated.

[0053] Retrieve the preset allowable offset threshold d0 from inside the control panel and compare it with the lateral offset distance d for analysis. d0 represents the maximum lateral offset threshold allowed for the conveyor frame 1, which is called the preset allowable offset threshold.

[0054] When d > d0, it is determined that the fabric position offset exceeds the limit, and a position correction signal is generated.

[0055] The fabric parameter analysis module generates three types of signals based on the above results: wrinkle treatment signal, tension adjustment signal, and position correction signal, and sends them to the fabric transportation control terminal.

[0056] When the fabric transportation control terminal receives the signals from the fabric transportation risk analysis module, it performs adjustments according to the following logic:

[0057] When the wrinkle treatment signal is triggered:

[0058] · Control the lifting cylinder 302 of the lower screed plate 304 to increase the height, so that the lower screed plate 304 and the upper screed plate 403 clamp the fabric.

[0059] · Start the heaters 303 inside the lower screed plate 304 and the upper screed plate 403, and release hot air through the first air dispersion holes 306 and the second air dispersion holes 404.

[0060] · Drive the circulation fan 5 to rotate at an accelerated speed, form an air flow cycle through the splicing valve 401 and the air return hole 405, and heat and flatten the fabric.

[0061] When the tension adjustment signal is triggered:

[0062] · Control the lifting cylinders 101 on both sides of the conveying frame 1 to adjust the height of the conveying and traction roller 102 according to the positive or negative value of ΔT;

[0063] · If T > T0 + ΔT0, it indicates that the tension is too large, and the conveying and traction roller 102 is raised to reduce the fabric tension;

[0064] · If T < T0 - ΔT0, it indicates that the tension is too small, and the conveying and traction roller 102 is lowered to increase the fabric tension.

[0065] When the position deviation correction signal is triggered:

[0066] Control the lifting cylinders 402 at both ends of the leveling frame 4 to drive the movable plate 601 of the limit frame 6 to move laterally, contact the edge of the fabric and apply a lateral force until d ≤ d0.

[0067] The above adjustment process realizes the dynamic calibration of the fabric flatness, tension and position through real-time feedback control, ensuring that the fabric always maintains a flat state during the transmission process.

[0068] Combining Embodiment 1 and Embodiment 2, it can be seen that through the deep integration of the temperature control system, mechanical structure and intelligent algorithm, on the premise of ensuring the flatness quality of the fabric, three breakthroughs are achieved, namely, the improvement of processing efficiency, the reduction of energy consumption and the reduction of maintenance costs. It not only protects the material characteristics of the fabric, but also conforms to the development trend of green manufacturing, providing an innovative solution with significant economic and environmental benefits for the automated garment industry.
