Description

Technical Field

[0001] This application relates to the field of fabric conveying, and in particular to a fabric conveying device for bag production. Background Technology

[0002] With the booming development of the luggage manufacturing industry, the market has increasingly stringent requirements for the quality and quantity of luggage products. To improve the waterproof performance of luggage, a waterproof layer needs to be adhered to the inside of the fabric used in luggage production. After multiple layers of fabric are stacked and cut, fabric with cutting defects needs to be separated from the stack of fabric.

[0003] In existing technologies, this type of sorting work is dominated by manual operation, requiring a large amount of manpower from fabric handling and conveying to quality inspection. This not only leads to low production efficiency, making it difficult to meet the needs of large-scale production, but also makes manual inspection highly susceptible to subjective factors, such as the fatigue level of inspectors and differences in individual experience, resulting in large fluctuations in the defect detection rate and a high average rate of missed defective products, which seriously affects the quality stability of subsequent finished bags and luggage.

[0004] On the other hand, in the fabric transfer process, after the sorting is completed, due to the light and soft nature of the fabric, it is difficult for manual labor to neatly arrange the sorted fabric. Due to the lack of effective automated connection and protection measures, the fabric is very prone to wrinkles, scratches and other damage, which reduces the economic benefits of enterprises.

[0005] Therefore, a fabric conveying device for bag production is proposed. Summary of the Invention

[0006] The purpose of this application is to automate fabric conveying and improve the precision of quality inspection, thereby increasing production efficiency, reducing labor intensity, decreasing defect rates, and enhancing fabric utilization.

[0048] The embodiments will be described clearly and completely with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application. Example

[0049] This invention provides a fabric conveying device for bag production. Please refer to [link / reference]. Figure 1 - Figure 13 This equipment mainly consists of a frame 1, a carrier 2, a conveyor plate 3, and an adjustment mechanism 4. It is used to inspect the front and back of thin fabrics that have been cut for bag production in order to remove defective products.

[0050] Please see Figure 1 The frame 1 serves as the basic support structure for the entire equipment, providing a stable installation platform for the carrier 2, conveyor plate 3, and adjustment mechanism 4.

[0051] Please see Figure 1 and Figure 9 - Figure 13The carrier 2 is provided in two symmetrically distributed sets, including a feeding carrier 201 for loading fabric to be inspected, a good product carrier 202 for loading inspected good product fabric, and a waste hopper 203 located between the two for loading inspected defective fabric. The carrier 2 includes a base 21, with four pairs of opposing columns 25 on the top of the base 21, and a lifting cylinder 23 fixed in the middle. The output end of the lifting cylinder 23 is connected to a support plate 22. One side of the base 21 is rotatably connected to the frame 1, and the tilt angle of the other side is adjusted by a tilting cylinder 24. A second linear module 251 is installed at the bottom of the columns 25, which can slide in the spacing adjustment groove 211 on the top of the base 21 to adjust the spacing of the four sets of columns 25, so that the support plate 22 can adapt to the carrying requirements of different sized cut fabrics.

[0052] Please refer to this first. Figure 10 To facilitate the spacing adjustment of the uprights 25 on the sides of the support plate 22 and the conveyor plate 3, the support plate 22 is provided with first card inlets 221 at its four corners that match the uprights 25, and the conveyor plate 3 is provided with second card inlets 34 at its four corners that match the uprights 25. Two sets of mounting seats 26 are symmetrically fixed to the top of the first card inlets 221 on the support plate 22. Horizontal grooves 261 are provided on opposite sides of the mounting seats 26. The two sets of mounting seats 26 are connected by a sliding rod 27. The two ends of the sliding rod 27 slide within the horizontal grooves 261, and the middle part slides within the vertical grooves 252 of the uprights 25. Through the design of the horizontal grooves 261, the vertical grooves 252, and the sliding rod 27, the support plate 22 can still achieve stable height adjustment by utilizing the extension and retraction of the lifting cylinder 23 after the spacing of the uprights 25 is adjusted, thus meeting the bearing requirements of fabrics 5 of different thicknesses.

[0053] Please refer to this first. Figure 11 To prevent the uprights 25 from squeezing and deforming the corners of the fabric 5 after the spacing is adjusted, rubber strips 253 are provided on the opposite sides of the uprights 25; to prevent the top of the fabric 5 carried by the bearing plate 22 from detaching, an elastic limiting block 254 is provided on one side of the top of the uprights 25, and the elastic limiting block 254 is used to lock into the top of the fabric pile to achieve the limiting.

[0054] Please see Figure 1 - Figure 8The conveyor plate 3 is also provided in two sets and symmetrically distributed, used to absorb the fabric from the feeding carrier 201 and inspect and classify it, or to place the inspected and qualified fabric into the good product carrier 202. The bottom of the conveyor plate 3 is provided with several negative pressure ports 31 for adsorbing fabric using negative pressure. Since one side of the bag fabric is coated with a waterproof coating, the negative pressure effect of the negative pressure ports 31 can be effectively used for fabric adsorption in this application. The bottom of the conveyor plate 3 is also fixed with a camera 32 and a supplementary light 33. During the adsorption of fabric, the quality of the fabric is inspected by the camera 32 and the supplementary light 33. The specific visual inspection scheme is as follows: When the fabric is placed on the support plate 22 of the feeding carrier 201, the tilting cylinder 24 adjusts the tilt angle of the machine base 21 so that the fabric is in a position that is easy for the conveyor plate 3 to adsorb and is conducive to visual inspection. Specifically, the fabric is in a state of being opposite and parallel to the conveyor plate 3. The lifting cylinder 23 lifts the support plate 22 to a suitable height so that the top layer of fabric always maintains a fixed height. After the upper layer of fabric is adsorbed and transferred, the lifting cylinder 23 lifts the support plate 22 up by the thickness of the fabric to maintain the height of the top layer of fabric and completes the preparation work.

[0055] The conveyor plate 3 on one side of the feeding carrier 201 moves downward under the drive of the first linear module 411 and moves along the through groove 11 to the first visual inspection area for visual inspection. After completing the visual inspection of the top of the fabric, the conveyor plate 3 continues to move downward to contact the top of the fabric and adsorbs the fabric through the bottom negative pressure port 31. When the conveyor plate 3 with the fabric adsorbed moves upward, under the adjustment of the adjustment mechanism 4, it gradually flips and is set relative to the conveyor plate 3 on the other side and enters the second visual inspection area. During the process of the two sets of conveyor plates 3 facing each other, the camera 32 and the supplementary light 33 on the conveyor plate 3 on one side of the good product carrier 202 are used to visually inspect the bottom of the fabric.

[0056] During the inspection process, if both sides of the fabric are good products, after the two sets of conveyor plates 3 are aligned, the negative pressure port 31 on the conveyor plate 3 on the good product carrier 202 side opens, while the negative pressure port 31 on the conveyor plate 3 on the feeding carrier 201 side closes, thereby completing the conveying of the fabric between the two sets of conveyor plates 3, and transferring it to the good product carrier 202 via the conveyor plate 3 on the good product carrier 202 side, where it is placed by the column 25.

[0057] If a defect occurs on either side of the fabric, the negative pressure ports 31 on both conveyor plates 3 will close simultaneously as they move towards each other. After the two conveyor plates 3 move away from each other, the fabric between them will automatically fall into the waste hopper 203.

[0058] In both the first and second visual inspection areas, a high-resolution camera 32 fixed to the bottom of the conveyor plate 3, in conjunction with a high-brightness supplementary light 33, captures multi-angle, high-definition images of the fabric. The camera 32 is installed at the center of the bottom of the conveyor plate 3 and has been precisely adjusted to ensure complete coverage of the fabric surface without blind spots. The captured images are transmitted to the image processing unit built into the equipment control system. Image recognition algorithms are used to compare and analyze the fabric's color and texture. By matching with a preset standard color library and texture template, the accuracy of the fabric color and the clarity and compliance of the texture are determined. For defect detection, the algorithm identifies abnormal pixel distributions in the image, such as black areas at holes or irregular shapes of stains, thereby accurately locating the defect's position and size.

[0059] Based on the image processing and analysis results, the system generates an inspection report. If the fabric quality is acceptable, the conveyor plate 3 transfers the fabric to the good product carrier 202; if defective products are detected, the conveyor plate 3 places the fabric in the waste hopper 203. For fabrics with minor defects that can be repaired, a dedicated placement area can be set up for easy subsequent processing. Simultaneously, the inspection results can be transmitted in real-time to the mobile phones or computer terminals of management personnel via a remote monitoring module, facilitating timely monitoring of production status and adjustment of equipment parameters or arrangement of subsequent processing measures.

[0060] Please refer to this first. Figure 4 It should be noted that a Y-shaped bracket 35 is fixed on the side of the conveyor plate 3 near the frame 1. One end of the Y-shaped bracket 35 is connected to the central shaft 36. The adjustment mechanism 4 is used to adjust the relative distance and relative angle between the two sets of conveyor plates 3. When the two sets of conveyor plates 3 move up to the highest point along the through groove 11, the distance between the two sets of conveyor plates 3 is equal to the thickness of the fabric 5. Specifically, the vertical distance between the conveyor plate 3 and the central shaft 36 can be adjusted according to the thickness of the fabric to be conveyed, so that the distance between the two sets of conveyor plates 3 after they are aligned is equal to the thickness of the fabric 5, in order to adapt to different fabric conveying requirements.

[0061] Please see Figure 2 - Figure 6 The adjustment mechanism 4 includes a limiting plate 41. Two sets of symmetrical first linear modules 411 are arranged on one side of the limiting plate 41, which cooperate with the guide rails 46 on the frame 1 to realize the movement of the limiting plate 41 on the frame 1. The frame 1 is provided with a through groove 11 between the two sets of guide rails 46. One end of the central shaft 36 passes through the through groove 11 and the limiting plate 41 and is connected to the angle rod 43. The first slider 431 and the second slider 432 are fixed at both ends of the angle rod 43, respectively.

[0062] Please refer to this first. Figure 4On the other side of the limiting plate 41, there are two sets of rotationally symmetrical arc-shaped grooves 412. One end of the first slider 431 and the second slider 432 slides within the arc-shaped grooves 412. Tension springs 44 are fixed between the two ends of the angle rod 43 and the corresponding arc-shaped grooves 412. An angle adjusting plate 45 is fixed on one side of the frame 1. The angle adjusting plate 45 is provided with adjusting grooves, including a first guide groove 451 and a second guide groove 452. The other end of the first slider 431 slides within the first guide groove 451, and the other end of the second slider 432 engages with the second guide groove 452.

[0063] Please refer to this first. Figure 6 Specifically, the first guide groove 451 includes a lower groove 4511 and an upper groove 4512. The vertical distance of the lower groove 4511 from the axis of the through groove 11 gradually increases from bottom to top. The difference between the vertical distance between the lowest and highest points of the lower groove 4511 and the axis of the through groove 11 is equal to the radius of the arc groove 412. The vertical distance of the upper groove 4512 from the axis of the through groove 11 gradually decreases from bottom to top. The difference between the vertical distance between the lowest and highest points of the upper groove 4512 and the axis of the through groove 11 is equal to one-third of the radius of the arc groove 412.

[0064] The second guide groove 452 is an open groove structure. The bottom of the second guide groove 452 is provided with an inlet notch 4521. The second guide groove 452 is arranged parallel to the lower groove 4511. The distance between the second guide groove 452 and the lower groove 4511 is equal to the distance between the first slider 431 and the second slider 432. The vertical distance of the second guide groove 452 from the axis of the through groove 11 gradually decreases from bottom to top. The difference between the vertical distance between the lowest point and the highest point of the second guide groove 452 and the axis of the through groove 11 is equal to one-third of the radius of the arc groove 412.

[0065] Please refer to this first. Figure 7 and Figure 8 The tension spring 44 has the elastic force to drive the first slider 431 and the second slider 432 to approach the corresponding arc groove 412. In the free state, the tension spring 44 is set at a 30-degree angle with the horizontal plane.

[0066] When the first slider 431 is moved to the connection node between the lower groove 4511 and the upper groove 4512, the second slider 432 is inserted into the second guide groove 452 through the inlet notch 4521, and the conveyor plate 3 is rotated ninety degrees and set at a sixty-degree angle with the horizontal plane.

[0067] When the first slider 431 moves away from the end of the upper groove 4512 away from the lower groove 4511, the second slider 432 slides along the second guide groove 452 to the end of the second guide groove 452, and the conveyor plate 3 flips again by thirty degrees and is set at a ninety-degree angle with the horizontal plane.

[0068] Working principle:

[0069] The stack of fabric cut in the previous process is placed on the support plate 22 of the feeding carrier 201. The tilt angle of the machine base 21 is adjusted by the flip cylinder 24 so that the fabric and the conveying plate 3 are in a relatively parallel state, which makes it easy for the conveying plate 3 to absorb the fabric. The lifting cylinder 23 can adjust the height of the support plate 22 according to the thickness of the fabric and in conjunction with the displacement sensor, so that the fabric at the top is kept at a fixed absorption height of the conveying plate 3. The conveying plate 3 absorbs or places the fabric through the negative pressure port 31 at the bottom.

[0070] During the adsorption process, the two sets of first linear modules 411 synchronously drive the two sets of limiting disks 41 to reciprocate up and down along the direction of the corresponding through groove 11, thereby adjusting the relative distance and relative angle of the two sets of conveying plates 3, so that the two sets of conveying plates 3 respectively perform the actions of adsorbing, conveying and placing the fabric between the feeding carrier 201 and the good product carrier 202.

[0071] Specifically, before the fabric is picked up by the conveyor plate 3 on one side, the top of the fabric is inspected by the camera 32 and the supplementary light 33. Before the two sets of conveyor plates 3 are aligned, the bottom of the fabric is inspected. Based on the inspection results, the conveyor plate 3 places the good fabric on the good product carrier 202 and the defective fabric into the waste hopper 203.

[0072] As the conveyor plate 3 moves up and down along the through groove 11, its angle can be automatically adjusted by the adjustment mechanism 4. When the tension spring 44 is in a free state, the conveyor plate 3 forms a 30-degree angle with the horizontal plane and is at its lowest point. At this time, the feeding carrier 201 loaded with cloth is kept parallel to the conveyor plate 3 by the adjustment of the tilting cylinder 24.

[0073] As the conveyor plate 3 moves upward along the through groove 11, the angle of the conveyor plate 3 changes as the first slider 431 slides in the first guide groove 451 and the second slider 432 engages with the second guide groove 452.

[0074] Specifically, when the first slider 431 moves from the bottom to the top of the lower groove 4511, it is pressed by the lower groove 4511, overcoming the elastic force of the tension spring 44, and moves along its arc-shaped groove 412. Since the vertical distance between the lower groove 4511 and the axis of the through groove 11 gradually increases from bottom to top, the difference between the vertical distance between its lowest point and the highest point and the axis of the through groove 11 is equal to the radius of the angle rod 43, causing the first slider 431 to rotate ninety degrees around the axis of the central shaft rod 36, thereby realizing the ninety-degree flip of the conveyor plate 3.

[0075] When the first slider 431 runs to the connection node between the lower groove 4511 and the upper groove 4512, the conveyor plate 3 rotates 90 degrees and forms a 60-degree angle with the horizontal plane. The second slider 432 is pre-engaged in the second guide groove 452 through the inlet notch 4521. In the subsequent displacement action, the second guide groove 452 and the second slider 432 cooperate to lead the movement. The conveyor plate 3 rotates 30 degrees again and forms a 90-degree angle with the horizontal plane, so as to achieve the purpose of the two sets of conveyor plates 3 facing each other and conveying the fabric.

[0076] This invention utilizes the cooperation between two sets of conveyor plates 3 equipped with negative pressure ports 31, cameras 32, and supplementary lights 33, and an adjustment mechanism 4 equipped with a limit plate 41 and an angle adjustment plate 45 to reciprocate the conveying of thin fabric between two sets of carriers. Simultaneously, it achieves double-sided visual inspection of the fabric, significantly reducing manual intervention in fabric conveying and inspection, greatly reducing the labor intensity of workers, improving the working environment, and improving fabric conveying efficiency, reducing human error, increasing the accuracy of defective product detection, and ensuring the accuracy of fabric classification through automated adsorption, conveying, and visual inspection processes.

[0077] The above description is only the best implementation method adopted in this application in combination with current practical needs, but the scope of protection of this application is not limited thereto.
