Description

Technical Field

[0001] The present invention relates to the technical field of clothing processing, and particularly to a detection device for clothing processing fabrics. Background Art

[0002] In the field of clothing processing, the quality inspection of fabrics has always been a key link to ensure the quality of the final products. However, there are many deficiencies in traditional fabric detection technologies.

[0003] The existing detection devices have relatively single functions for stretching detection of fabrics. Especially, it is difficult to achieve stretching detection when the fabric is in a twisted state. Due to the lack of special structures and mechanisms, traditional devices cannot place the fabric in a twisted state for stretching, and thus cannot simulate the complex stress conditions that the fabric may withstand during actual use. They cannot provide accurate performance evaluations for clothing fabrics (such as sportswear fabrics) that need to withstand stretching and twisting forces, and thus cannot accurately judge the quality of the fabrics. This may lead to misjudging some fabrics with quality problems in actual use as qualified.

[0004] For the detection of the appearance quality of fabrics, traditional detection methods mainly rely on manual observation or simple devices, and there are great limitations in the comprehensiveness and accuracy of detection. On the one hand, the detection devices can often only detect appearance indicators such as the color of the fabric from a single angle or a few angles, and it is difficult to comprehensively check the color changes of the fabric at different angles and in different states. It is impossible to accurately capture the subtle color differences of the fabric in the non-stretched and non-twisted and stretched states, which may cause some fabrics with quality problems due to color issues to enter the production process and affect the appearance quality of the final clothing products. Summary of the Invention

[0005] The present invention relates to a detection device for clothing processing fabrics. Its industrial cameras are evenly arranged and the distance between the cameras and the fabric is the same. With the assistance of the lights of an adjustable light board, it can not only detect the color difference of the fabric at different angles when the fabric is not stretched, but also detect the color changes when the fabric is in a twisted and stretched state, and can comprehensively and meticulously check the appearance of the fabric, greatly improving the comprehensiveness and accuracy of the appearance quality detection.

[0006] The invention provides a detection device for fabrics for garment processing, which specifically comprises: a detection frame; two conveying rollers are respectively installed on the two end frames of the detection frame to rotate up and down parallel to each other, and the conveying rollers are used to convey the fabric from the detection frame into and out of the other end; two twisting rollers are provided on the middle part of the detection frame in a vertical manner parallel to each other, and the fabric passing through the conveying rollers at one end is twisted and sent to the other end after passing through the twisting rollers, and the conveying path is twisted 180 degrees; a side hanging frame is provided at the long side of one side of the detection frame, the inner side of the side hanging frame is connected to an appearance quality detection frame, the end of the appearance quality detection frame is fixedly connected to a track rod consistent with the twisting direction of the conveyed fabric, and industrial cameras are evenly spaced on the track rod; a back plate is blocked on the long side of the detection frame opposite to the side hanging frame, and a light board for assisting the industrial camera to detect the fabric is provided on the inner side wall of the back plate; a stretching frame for stretching the two ends of the fabric outward is also provided at the upper ends of the conveying rollers at both ends of the detection frame, and an auxiliary follow-up stretching seat is provided on the inner side of the detection frame below the stretching frame.

[0007] Optionally, a display screen is also provided on the side hanging bracket, and a reduction motor is fixedly installed in the middle of the lower end of the side hanging bracket, and the reduction motor is connected to a horizontal driving rod. Worms are respectively provided at both ends of the driving rod to engage with worm gears at both ends of the conveying rollers below at both ends of the detection frame. The rotation of the driving rod drives the conveying rollers at both ends to rotate and transport the fabric from one end to the other.

[0008] Optionally, the upper ends of the side hanging frames and the back plate are provided with pull-type folding curtains, and both ends of the slideways on the side hanging frames and the back plate adapted to the ends of the folding curtains are open structures for facilitating the disassembly of the folding curtains.

[0009] Optionally, the camera head of each of the industrial cameras is facing the fabric and is at the same distance from the fabric.

[0010] Optionally, two opposite clamping plates are symmetrically fixed on the side walls at both ends of the detection frame below the stretching frame, and a panel is vertically slidably provided between the two clamping plates.

[0011] Optionally, tensioning adjustment bolts are provided at both ends of the conveyor roller at the top, and the tensioning adjustment bolts are used to adjust the distance between the upper and lower conveyor rollers. A spline shaft is provided near the two ends of the conveyor roller, and a correction head is slidably sleeved on the spline shaft. The outer diameter of the correction head is consistent with the outer diameter of the conveyor roller, and a spiral protrusion is provided on the roller surface of the correction head for smoothing the edge of the passing fabric outward. The spline shaft on the inner side of the correction head is provided with a first spring that pushes the correction head outward.

[0012] Optionally, a cylinder is vertically provided in the middle of the stretching frame, and the lower end of the piston rod of the cylinder is fixedly connected to an inverted "L"-shaped connecting plate, which is vertically slidably connected to the outer end of the panel, and the lower end of the connecting plate is fixedly connected to an upward strong magnetic plate, which is tangent to the panel, and a rectangular embedding groove is provided on the inner wall of the panel, in which a magnet is provided, and the strong magnetic plate and the magnet in the embedding groove have different magnetic properties. When the piston rod of the cylinder moves downward, due to the friction between the two ends of the panel and the card plate, the connecting plate first moves downward with the strong magnetic plate and then drives the panel to move downward, and the inner wall of the panel is tangent to the passing fabric.

[0013] Optionally, a buffer rod is vertically slidably installed on the follow-up stretching seat, and a magnetic sleeve is fixedly connected between the upper ends of the two buffer rods. The outer side wall of the magnetic sleeve is tangent to the inner side of the conveyed fabric, and cooperates with the panel to clamp the fabric in the middle. A second spring is mounted on the buffer rod to push the magnetic sleeve upward, and a magnetic plate is horizontally inserted in the magnetic sleeve. The magnetic properties of the magnetic plate and the magnet in the embedding groove are different, and a buckle is provided on the outer side wall of the magnetic sleeve to prevent the magnetic plate from falling out.

[0014] A detection method for a detection device for garment processing fabrics. When a tensile test is required for a fabric in a twisted state, the cylinder operates, the reduction motor stops, the worm of the drive rod and the worm wheel of the conveyor roller are self-locked, and the panel moves downward under the push of the piston rod of the cylinder and passes the position of the magnetic sleeve. The magnetic plate is attracted by the magnet in the embedded groove and squeezes the fabric into the embedded groove. The magnetic sleeve part continues to move downward with the panel, cooperating with the conveyor roller to stretch the fabric in a twisted state. The industrial camera on the trace rod detects color changes in the twisted and stretched state in cooperation with the light board.

[0015] After the stretch test is completed in the twisted state of the fabric, the piston rod of the cylinder is reset and pulled up. The connecting plate first drives the strong magnetic plate to move up. When the strong magnetic plate passes the insert plate, the strong magnet forces the magnetic plate to dislodge from the groove. The insert plate and the magnetic sleeve separate and reset, and the fabric is in a free state.

[0016] When only color change detection of the fabric in an unstretched state is required, the geared motor drives the drive rod to rotate, and the rotating conveyor roller causes the fabric to be twisted 180 degrees and continuously conveyed under the action of the twisting roller. With the assistance of the light panel, the industrial camera on the track rod can detect the color difference of the fabric at various angles.

[0017] This invention provides a testing device for garment processing fabrics, which has the following beneficial effects:

[0018] A straightening head slides onto the splined shaft near each end of the conveyor roller. Driven by a first spring, its outer diameter matches the roller's, and a spiral protrusion on the roller surface smoothes the fabric edges outward. This structure ensures the smoothness of the fabric edges during conveyance, overcoming the existing problem of wrinkling or uneven edges during conveyance. This provides a sound foundation for subsequent inspection operations and improves the accuracy of test results.

[0019] Two twisting rollers, arranged vertically and parallel to each other in the center of the testing frame, cause fabrics passing through one roller to twist 180 degrees as they pass through the other rollers. This unique design, relatively uncommon in existing technology, allows fabrics to twist at specific angles during transport, enabling testing of fabric performance under varying degrees of distortion. This design better simulates the distortion conditions fabrics may encounter in actual use and is particularly suitable for garment fabrics that must withstand torsional stress, such as tights and sportswear, enabling a more comprehensive assessment of fabric performance.

[0020] Industrial cameras are evenly spaced on the track rods connected to the end of the appearance quality inspection frame. The cameras are all facing the fabric and at the same distance from the fabric. At the same time, they are assisted by the light panel on the inner wall of the back panel. This structure realizes multi-angle and all-round inspection of the appearance quality of the fabric based on existing technologies. Whether the fabric is in an unstretched state or in a twisted and stretched state, the color difference and color change of the fabric can be carefully inspected at different angles through the industrial cameras. Compared with traditional single-angle or limited-angle appearance inspection, it can capture more subtle color differences, greatly improving the comprehensiveness and accuracy of appearance quality inspection, avoiding defects in the final clothing product due to appearance quality problems, and helping to improve the overall quality and aesthetics of the clothing.

[0021] The design of the stretching frame and its accessories (including cylinders, connecting plates, strong magnetic plates, panels, magnetic sleeves, etc.) has brought innovation to the stretching test of fabrics. When conducting stretching tests on fabrics in a twisted state, the cylinder works to move the piston rod downward, and utilizes the friction, magnetic attraction, and spring force (such as the second spring) between the components, and the coordinated work between the strong magnetic plates, panels, and magnetic sleeves to effectively stretch and clamp the fabric in a twisted state. This kind of stretching test in a twisted state is lacking in the existing technology. It can accurately simulate the stretching of fabrics under complex stress conditions in actual use, provide more comprehensive data for fabric performance evaluation, and make the test results closer to the performance of fabrics in actual applications. It improves the accuracy and reliability of the evaluation of the tensile performance of garment processing fabrics and ensures the quality stability of the fabric during use.

[0022] The various components of the testing device work together in a carefully designed manner to ensure the smooth operation of the entire testing process. For example, the tension frame, follow-up tension seat, straightening head, and magnetic sleeve, through the cooperation of springs and magnets, as well as the unique design of the tension frame's cylinders and panels, enable precise handling of the fabric under different testing conditions. Compared with traditional devices, this device exhibits higher stability and reliability in fabric stretching, clamping, and twisting operations, reducing testing errors and malfunction risks caused by poor coordination between components, and ensuring the continuity and accuracy of the testing process.

[0023] The side hangers and back panel feature floor-to-ceiling folding curtains with open structures at both ends of the slide rails, allowing for easy installation and removal. These curtains not only provide protection and light blocking but also allow for flexible adjustment of the testing environment to meet specific needs. Traditional testing devices often lack this ability to flexibly adjust the testing environment. This invention, through its design, effectively reduces interference from the external environment, further ensuring the stability and reliability of the test results and providing excellent environmental conditions for high-quality fabric testing.

[0024] In summary, the garment processing fabric inspection device of the present invention, through the innovation and optimization of the above-mentioned mechanical structure, overcomes the shortcomings of the prior art in many aspects, from fabric conveying, twisting treatment, appearance quality inspection, tensile testing to the overall structural coordination and environmental adjustment. It provides the garment processing industry with a more efficient, accurate, stable and multifunctional fabric inspection solution, which helps to improve the quality and market competitiveness of garment products and meets the needs of modern garment processing for high-quality fabric inspection.

[0050] Example 1: Please refer to Figures 1 to 9 :

[0051] This invention proposes a testing device for garment processing fabrics, comprising: a testing frame 1; two conveying rollers 2 are respectively mounted vertically and rotatably on both ends of the frame 1, the conveying rollers 2 being used to convey fabric from the testing frame 1 into the other end and out the other end; two twisting rollers 3 are vertically and horizontally parallel to each other in the middle of the testing frame 1, the fabric passing through one end of the conveying roller 2 is twisted and conveyed to the other end of the conveying path at a 180-degree angle after passing through the twisting rollers 3; a side hanger 4 is provided on one long side of the testing frame 1, the inner side of the side hanger 4 being connected to an appearance quality... The inspection frame 8 has a fixed connection at its end to a track rod 801 that is consistent with the twisting direction of the conveyed fabric. Industrial cameras 802 are evenly spaced on the track rod 801. A back plate 6 is sealed on the long side of the inspection frame 1 opposite to the side hanger 4. A light plate 601 for assisting the industrial cameras 802 in inspecting the fabric is provided on the inner wall of the back plate 6. A stretching frame 9 for stretching the two ends of the fabric outward is also provided at the upper end of the conveying rollers 2 at both ends of the inspection frame 1. A follow-up stretching seat 10 is provided on the inner side of the inspection frame 1 below the stretching frame 9.

[0052] The side hanger 4 is also equipped with a display screen 5. A reduction motor 7 is fixedly installed in the middle of the lower end of the side hanger 4. The reduction motor 7 is connected to a horizontal drive rod 701. The two ends of the drive rod 701 are respectively equipped with worm gears that mesh with the worm wheels 201 at both ends of the conveyor rollers 2 located below the two ends of the detection frame 1. The rotation of the drive rod 701 drives the conveyor rollers 2 at both ends to rotate and transport the fabric from one end to the other end.

[0053] Among them, the upper ends of the side brackets 4 and the back panel 6 are provided with a pull-type folding curtain 11, and both ends of the slides on the side brackets 4 and the back panel 6 that are adapted to the ends of the folding curtain 11 are open structures that facilitate the disassembly of the folding curtain 11.

[0054] The camera head of each industrial camera 802 is facing the fabric and is at the same distance from the fabric.

[0055] Two opposite clamping plates 101 are symmetrically fixed on the side walls at both ends of the detection frame 1 below the stretching frame 9 , and an insert plate 904 is vertically slidably provided between the two clamping plates 101 .

[0056] Among them, tensioning adjustment bolts 202 are provided at both ends of the upper conveyor roller 2. The tensioning adjustment bolts 202 are used to adjust the distance between the upper and lower conveyor rollers 2. A spline shaft 205 is provided near the two ends of the conveyor roller 2. A correction head 204 is slidably sleeved on the spline shaft 205. The outer diameter of the correction head 204 is consistent with the outer diameter of the conveyor roller 2. A spiral protrusion is provided on the roller surface of the correction head 204 for smoothing the edge of the passing fabric outward. The spline shaft 205 on the inner side of the correction head 204 is equipped with a first spring 206 that pushes the correction head 204 outward.

[0057] The second embodiment is based on the first embodiment. A cylinder 901 is vertically provided in the middle of the stretching frame 9. The lower end of the piston rod of the cylinder 901 is fixedly connected to an inverted "L"-shaped connecting plate 902. The connecting plate 902 is vertically slidably connected to the outer end of the panel 904, and the lower end of the connecting plate 902 is fixedly connected to an upward strong magnetic plate 903. The strong magnetic plate 903 is tangent to the panel 904. A rectangular embedding groove 9041 is provided on the inner wall of the panel 904. A magnet is provided in the embedding groove 9041. The strong magnetic plate 903 and the magnet in the embedding groove 9041 have different magnetic properties. When the piston rod of the cylinder 901 moves downward, due to the friction between the two ends of the panel 904 and the clamping plate 101, the connecting plate 902 first moves downward with the strong magnetic plate 903 and then drives the panel 904 to move downward. The inner wall of the panel 904 is tangent to the passing fabric.

[0058] Among them, a buffer rod 1001 is vertically slidably installed on the follow-up stretching seat 10, and a magnetic sleeve 1002 is fixedly connected between the upper ends of the two buffer rods 1001. The outer side wall of the magnetic sleeve 1002 is tangent to the inner side of the conveyed fabric, and cooperates with the inlay plate 904 to clamp the fabric in the middle. A second spring 1003 is installed on the buffer rod 1001 to push the magnetic sleeve 1002 upward. A magnetic plate 1004 is horizontally inserted in the magnetic sleeve 1002. The magnetic plate 1004 has different magnetic properties from the magnet in the inlay groove 9041. A buckle 1005 is provided on the outer wall of the magnetic sleeve 1002 to prevent the magnetic plate 1004 from falling out.

[0059] A detection method for a detection device for garment processing fabrics: When a tensile test is required for the fabric in a twisted state, the cylinder 901 operates, the reduction motor 7 stops, the worm of the drive rod 701 and the worm wheel 201 of the conveyor roller 2 are self-locked, and the panel 904 moves downward under the push of the piston rod of the cylinder 901 and passes the position of the magnetic sleeve 1002. The magnetic plate 1004 is attracted by the magnet in the embedded groove 9041 to squeeze the fabric and insert it into the embedded groove 9041. The magnetic sleeve 1002 partially follows the panel 904 and continues to move downward, cooperating with the conveyor roller 2 to stretch the fabric in a twisted state. The industrial camera 802 on the trace rod 801 detects color changes in the twisted and stretched state in cooperation with the light board 601.

[0060] When the tensile test of the fabric is completed in a twisted state, the piston rod of the cylinder 901 is reset and pulled up, and the connecting plate 902 first drives the strong magnetic plate 903 to move upward. When the strong magnetic plate 903 passes the inlay plate 904, the strong magnetism forces the magnetic plate 1004 to disengage from the inlay groove 9041. The inlay plate 904 and the magnetic sleeve 1002 are separated and reset, and the fabric is in a free state.

[0061] When only the color change detection of the fabric is required when it is not stretched, the reduction motor 7 drives the driving rod 701 to rotate, and the conveying roller 2 rotates to drive the fabric to be twisted 180 degrees under the action of the twisting roller 3 for continuous conveying. With the assistance of the light board 601, the industrial camera 802 on the track rod 801 can detect the color difference of the fabric at various angles.

[0062] The working principle of this embodiment is as follows:

[0063] First, the fabric to be inspected is placed on the conveyor roller 2 at one end of the inspection frame 1. The reduction motor 7 is started, and the reduction motor 7, through the drive rod 701 and the worm gears at both ends, meshes with the worm wheels 201 at both ends of the conveyor roller 2 located at the lower ends of the inspection frame 1, driving the conveyor roller 2 to rotate, thereby conveying the fabric from one end of the inspection frame 1 to the other. During the conveying process, the tension adjustment bolt 202 of the upper conveyor roller 2 can adjust the distance between the upper and lower conveyor rollers 2 to accommodate fabrics of different thicknesses. At the same time, the straightening head 204 on the conveyor roller 2, under the action of the first spring 206, has the same outer diameter as the conveyor roller 2, and the spiral protrusions on the roller surface can smooth the edges of the fabric passing by outwards, ensuring the flatness of the fabric during the conveying process.

[0064] When a stretch test is required for the fabric under twisted conditions, cylinder 901 starts working while reduction motor 7 stops. At this time, the worm gear of drive rod 701 and the worm wheel 201 of conveyor roller 2 self-lock, stopping the fabric conveying. The piston rod of cylinder 901 moves downward, driving the inverted "L"-shaped connecting plate 902 downward. Connecting plate 902 and strong magnetic plate 903 move downward synchronously. Due to the friction between the two ends of insert plate 904 and clamping plate 101, initially connecting plate 902 moves downward with strong magnetic plate 903, and then drives insert plate 904 downward. When insert plate 904 passes the position of magnetic sleeve 1002, magnetic plate 1004 is attracted by the magnet in groove 9041 and squeezes the fabric into groove 9041. The magnetic sleeve 1002 part continues to move downward with insert plate 904. During this process, under the action of the second spring 1003, the outer end sidewall of the magnetic sleeve 1002 is tangent to the inner side of the conveyed fabric, and cooperates with the insert 904 to clamp the fabric in the middle, thereby stretching the fabric in a twisted state. At the same time, the industrial cameras 802, which are evenly spaced on the track rods 801 on the appearance quality inspection frame 8 inside the side hanger 4, cooperate with the light plate 601 on the inner sidewall of the back plate 6 to detect the color change of the fabric in the twisted and stretched state.

[0065] When the stretching test of the fabric is completed in a twisted state, the piston rod of the cylinder 901 is reset and pulled up, and the connecting plate 902 will first drive the strong magnetic plate 903 to move up. When the strong magnetic plate 903 passes the inlay plate 904, the strong magnetism forces the magnetic plate 1004 to disengage from the inlay groove 9041, and the inlay plate 904 and the magnetic sleeve 1002 are separated and reset respectively, and the fabric returns to a free state.

[0066] When only color change detection of the fabric in an unstretched state is required, the geared motor 7 is restarted. The geared motor 7 drives the drive rod 701 to rotate, and the conveyor roller 2 rotates accordingly. The fabric is continuously conveyed by twisting 180 degrees under the action of the twisting roller 3. During this process, with the assistance of the light from the light panel 601, the industrial camera 802 on the track rod 801 can detect color difference of the fabric at various angles.

[0067] Throughout the inspection process, the floor-to-ceiling folding curtains 11 on the side hangers 4 and back panel 6 can be easily installed and removed through the open structures at both ends of the slide rails, providing a certain degree of protection and light blocking. Meanwhile, the tension frame 9, follow-up tension seat 10, straightening head 204, magnetic sleeve 1002, and other components on the inspection frame 1 work together, along with the cooperation of springs, magnets, and other structures, to ensure smooth operation and inspection of the fabric under different inspection conditions. Through the cooperation of the industrial camera 802 and the light panel 601, the appearance quality of the garment processing fabric under different conditions can be inspected to meet various inspection needs.
