Description

Technical Field

[0001] This invention relates to the field of textile equipment technology, specifically to an intelligent fabric inspection machine with double-sided marking function and its control method. Background Technology

[0002] Fabric inspection machines are essential specialized equipment used in the garment industry to inspect single and double width fabrics such as cotton, linen, and silk before production. They play a vital role in textile production. Current fabric inspection machines typically provide the necessary hardware environment for inspection. The inspection work is usually carried out on an inspection table, where the fabric is continuously unfolded in sections. Sufficient light is provided by a light source at the top of the inspection table, and the operator relies on visual observation to identify fabric defects, color differences, and damage in order to complete the length recording and roll-up processing.

[0003] When inspecting fabrics, most fabric inspection machines require workers to find defects, which not only greatly increases the workload of workers but also reduces work efficiency, thereby increasing production costs. To address this, there is an existing automated fabric inspection machine that uses conveyor rollers to transport the fabric, multiple cameras to monitor the fabric in real time, and a marking structure to mark the defects on the fabric.

[0004] However, existing technologies typically use a fabric inspection table to support the fabric, and a marking structure is pressed onto the fabric to make marks. This is suitable for marking when defects appear on the upper surface of the fabric. However, since the fabric has two ends, the existing technology cannot simultaneously detect and mark defects on both ends of the fabric. Summary of the Invention

[0005] Therefore, the present invention provides an intelligent fabric inspection machine with double-sided marking function and its control method, which effectively solves the problem that the existing fabric inspection structure cannot simultaneously detect and mark defects on both the upper and lower ends of the fabric.

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] like Figure 1and Figure 2 As shown, the present invention provides an intelligent fabric inspection machine with double-sided marking function, comprising a frame 1, a movable roller group 2, and a detachable support base 3.

[0055] The frame 1 has a drive roller 4 rotatably mounted on its top. The drive roller 4 is used to convey the fabric 5. The frame 1 is equipped with a guide roller 6, which is located at the downstream end of the drive roller 4. A first drive motor is fixedly installed on the frame 1 near the drive roller 4 and the guide roller 6. The output end of the first drive motor is connected to the drive roller 4 and the guide roller 6.

[0056] The movable roller group 2 is located between the drive roller 4 and the guide roller 6. The movable roller group 2 consists of movable rollers 21 arranged in parallel. The fabric 5 passes through the movable rollers 21. An arc-shaped slide rail 7 is provided on the side of the movable roller group 2. A sliding shaft 10 is coaxially arranged on the movable roller 21. The sliding shaft 10 moves along the slide rail 7.

[0057] The detachable support base 3 is disposed between the movable roller 21 and the guide roller 6. The detachable support base 3 is composed of a detachable first support base 31 and a second support base 32. One end face of the upper end face and the lower end face of the first support base 31 and the second support base 32 supports the fabric 5. Marking devices 8 are provided on both the upper and lower end faces of the detachable support base 3. The marking devices 8 are used to affix labels to the defective positions on the fabric 5 where there are defects.

[0058] Twelve cameras 11 and an automatic light source 12 are installed between the drive roller 4 and the movable roller group 2. The cameras 11 face the upper and lower ends of the fabric 5 to detect defects on the upper and lower ends of the fabric 5. A sliding drive 9 is provided in the slide rail 7. The sliding drive 9 is used to drive the fabric 5 through the movable roller group 2 to move the fabric 5 to the end of the fabric 5 with defects when defects are detected on different ends of the fabric 5.

[0059] In this embodiment of the invention, the camera 11 is mainly used to detect defects, such as color difference, holes, broken yarn, stains, creases, knots, and rough yarn. The fully automatic inspection of fabric defects ensures the continuity and accuracy of the inspection. The automatic light source 12 is set to at least two sets, eliminating the need for manual input of fabric color, thickness, and brightness. It can be automatically adjusted according to the actual imaging effect of the fabric 5, avoiding problems such as decreased detection rate due to light source aging.

[0060] Both drive roller 4 and guide roller 6 are used to move the fabric 5 forward.

[0061] In this invention, a detachable support base 3 is provided between the movable roller 21 and the guide roller 6. Marking devices 8 are provided on both the upper and lower surfaces of the detachable support base 3. The marking devices 8 are used to affix labels to the defective positions on the fabric 5. The camera 11 is positioned facing the upper and lower surfaces of the fabric 5 to detect defects on the upper and lower surfaces of the fabric 5. The sliding drive component 9 is used to drive the fabric 5 to move to the defective end surface of the fabric 5 close to the marking device 8 when defects are detected on different end surfaces of the fabric 5, thereby realizing double-sided detection and marking of the fabric 5.

[0062] In this invention, the sliding shaft 10 can move along the slide rail 7, and the movable roller 21 can also move along the slide rail 7. To this end, the invention is designed as follows: a slide seat 13 is slidably arranged inside the slide rail 7, the sliding shaft 10 is fixedly installed on the slide seat 13, a sliding groove 14 is provided inside the slide rail 7, and the slide seat 13 is slidably arranged inside the sliding groove 14.

[0063] In the above embodiment, the slide block 13 can slide in the sliding groove 14, thereby driving the movable roller 21 to move along the slide rail 7. Moving upward can bring it closer to the upper marking device 8, and moving downward can bring it closer to the lower marking device 8.

[0064] To drive the slide block 13 to slide within the sliding groove 14, the present invention provides a sliding drive component 9. The sliding drive component 9 of the present invention adopts the following preferred embodiments, such as... Figure 1 As shown, the sliding drive component 9 includes a drive compartment 91 disposed on the side of the slide rail 7, meshing teeth 92 are evenly spaced on the side of the slide block 13, a slot is opened on the side of the slide rail 7, a second drive motor is disposed in the drive compartment 91, and a transmission gear 93 is connected to the output end of the second drive motor. The tooth tip of the transmission gear 93 extends into the slot and meshes with the meshing teeth 92.

[0065] The second drive motor drives the transmission gear 93 to rotate, and the rotation of the transmission gear 93 drives the meshing teeth 92 to move, thereby causing the slide block 13 to slide in the sliding groove 14, and causing the movable roller 21 to move along the slide rail 7.

[0066] In this invention, the detachable support 33 is composed of a first support 31 and a second support 32. Under normal transportation conditions, there is a certain gap between the first support 31 and the second support 32. At this time, the fabric 5 can pass through the gap between the first support 31 and the second support 32. When the fabric 5 needs to be marked as it moves upward with the movable roller 21, the first support 31 and the second support 32 need to be connected into a whole, and the upper ends of the first support 31 and the second support 32 support the fabric 5.

[0067] In order to ensure that the upper surfaces of the first support 31 and the second support 32 smoothly enter the bottom of the fabric 5 and properly support the taut fabric 5, the present invention is designed as follows: Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, both the first support base 31 and the second support base 32 are provided with mounting cavities 33. The first support base 31 and the second support base 32 are provided with horizontal grooves 34 and vertical grooves 35, which are connected. The top of the first support base 31 and the side wall at least partially connected to the top are provided with openings 36, and a support plate 37 is rotatably installed in the openings 36.

[0068] like Figure 3 and Figure 5 As shown, the support plate 37 is initially lower than the upper surfaces of the first support base 31 and the second support base 32. That is, the support plate 37 forms a certain angle with the upper surfaces of the first support base 31 and the second support base 32. The main reason why the support plate 37, which is on the inside, is lower than the upper surfaces of the first support base 31 and the second support base 32 is that the support plate 37 can smoothly enter the bottom of the fabric 5 during the translation process. This will prevent the first support base 31 from pushing the edge of the fabric 5 and causing wrinkles when the fabric 5 is not fully taut, which would prevent the subsequent marking from being completed.

[0069] During the translation process of the support plate 37 following the first support seat 31 and the second support seat 32, the support plate 37 can smoothly enter the bottom of the fabric 5. However, at this time, the top of the support plate 37 cannot support the fabric 5. In order to ensure that the support plate 37 can remain flush with the upper surface of the first support seat 31 and the second support seat 32 when the first support seat 31 and the second support seat 32 are combined, the present invention also makes the following design: a movable horizontal block 38 is movably arranged in the horizontal groove 34, and an extrusion column 39 is provided at the end of the movable horizontal block 38. The extrusion column 39 penetrates the outer wall of the first support seat 31 and the second support seat 32. A through groove 310 is opened on the outer wall of the first support seat 31 and the second support seat 32. The extrusion column 39 passes through the through groove 310 and its end extends to the outside of the through groove 310. A connecting spring 311 is connected in the first support seat 31 and the second support seat 32. The connecting spring 311 is wrapped around the extrusion column 39 and its end is connected to the extrusion column 39. A first engaging inclined surface 312 is provided at the end of the movable horizontal block 38.

[0070] A movable vertical block 313 is movably disposed within the vertical groove 35. A second engaging inclined surface 314 is provided at the bottom of the movable vertical block 313. The first engaging inclined surface 312 and the second engaging inclined surface 314 engage. A support rod 315 is connected to the top of the movable vertical block 313. A movable groove 316 is provided at the bottom of the support plate 315. A slider 317 is movably disposed within the movable groove 316. The top of the support rod 315 is rotatably connected to the slider 317. Figure 7 As shown, the slider 317 is a block-shaped body with protrusions 318 on both sides, and the inner wall of the movable groove 316 is provided with a groove 319 that mates with the protrusions 318.

[0071] In the above embodiment, when the first support 31 and the second support 32 approach each other, the extrusion columns 39 abut against each other. Under the mutual pushing action of the two extrusion columns 39, the extrusion columns 39 gradually move into the through groove 310, the connecting spring 311 is gradually stretched, and the extrusion columns 39 drive the movable horizontal block 38 to gradually move away from the extrusion columns 39. Since the first engaging inclined surface 312 and the second engaging inclined surface 314 engage, the movable horizontal block 38 drives the movable vertical block 313 to move upward during its movement, causing the support rod 315 to move upward. Figure 4 and Figure 6 As shown, during the upward movement of the support rod 315, the support plate 37 is driven to gradually rotate upward until it is flush with the upper surface of the first support seat 31 and the second support seat 32.

[0072] Under the action of the connecting spring 311, when the first support seat 31 and the second support seat 32 move away from each other, the pressing column 39 returns to its initial position. Correspondingly, the movable vertical block 313 and the support rod 315 also return to their initial positions. In order to make the movable vertical block 313 return to its initial position smoothly, a connecting spring 311 can also be set between the support rod 315 and the vertical groove 35. When the connecting spring 311 moves left and right, the movable vertical block 313 returns to its initial position.

[0073] In order to drive the movement of the first support 31 and the second support 32, the present invention also makes the following design: the bottom of the first support 31 and the second support 32 are provided with threaded grooves 320, a translation drive motor 321 is installed on the frame 1, and a drive screw 322 is connected to the output end of the translation drive motor 321. The drive screw 322 cooperates with the threaded groove 320.

[0074] The translation drive motor 321 drives the drive screw 322 to rotate. Under the rotation of the drive screw 322, the first support 31 and the second support 32 move closer to each other or further away from each other.

[0075] In this invention, a marking device 8 is used to mark the location of defects on the fabric 5. The marking device 8 of this invention adopts the following preferred embodiments, such as... Figure 8 and Figure 9 As shown, the marking device 8 includes a movable mounting frame 81 disposed above and below the first support 31 and the second support 32, a movable seat 82 movably disposed on the movable mounting frame 81, and a marking side compartment 83 disposed on the movable seat 82. There are two marking side compartments 83, and a connecting silo 84 is disposed between the marking side compartments 83. A marking drive shaft 85 and a drive cylinder 86 are disposed inside the connecting silo 84. The marking drive shaft 85 is disposed at the output end of the drive cylinder 86. A through-hole 87 is opened at the bottom of the connecting silo 84 for the marking drive shaft 85 to pass through.

[0076] One marking side compartment 83 is equipped with a first roller 88, and the other marking side compartment 83 is equipped with a second roller 89. The first roller 88 is wound with marking release paper 810, and marking stickers 811 are evenly attached to the marking release paper 810. The marking release paper 810 passes through the bottom of the marking side compartment 83, passes through the bottom of the connecting silo 84, enters the other marking side compartment 83, and is wound on the second roller 89. The second roller 89 and the first roller 88 are both connected to a third drive motor.

[0077] The third drive motor drives the first roller 88 and the second roller 89 to rotate, so that the marking sticker 811 is transported to the underside of the alignment marking drive shaft 85. When the defect position of the fabric 5 is transported to the corresponding position, the drive cylinder 86 drives the marking drive shaft 85 to move towards the fabric 5. The marking release paper 810 gradually moves away from the through-hole 87 position, and the marking sticker 811 gradually moves closer and sticks to the fabric. During the above process, the third drive motor drives the marking release paper 810 outside the first roller 88 and the second roller 89 to become longer. Then, the third drive motor drives the marking release paper 810 outside the first roller 88 and the second roller 89 to become shorter and return to the initial state. The third drive motor continues to drive the first roller 88 and the second roller 89 to rotate, so that the next marking sticker 811 is transported to the underside of the alignment marking drive shaft 85.

[0078] In summary, the main implementation process of this invention is as follows:

[0079] The fabric 5 is transported by drive roller 4 and guide roller 6, and the defects are detected by camera 11. When a defect is detected, it is determined whether the defect is located on the upper or lower surface.

[0080] Assuming the defect is located on the upper surface, the second drive motor drives the transmission gear 93 to rotate, and the rotation of the transmission gear 93 drives the meshing gear 92 to move, thereby causing the slide block 13 to slide in the sliding groove 14, and causing the movable roller 21 to move along the slide rail 7, and the fabric 5 gradually approaches the marking device 8.

[0081] The translation drive motor 321 drives the drive screw 322 to rotate. Under the rotation of the drive screw 322, the first support seat 31 and the second support seat 32 move closer to each other. As the support plate 37 moves along with the first support seat 31 and the second support seat 32, the support plate 37 can smoothly enter the bottom of the fabric 5. The two extrusion columns 39 abut against each other. Under the mutual pushing action of the two extrusion columns 39, the extrusion columns 39 gradually move into the through groove 310. The connecting spring 311 is gradually stretched. The extrusion columns 39 drive the movable horizontal block 38 to gradually move away from the extrusion columns 39. During the movement of the movable horizontal block 38, the movable vertical block 313 moves upward, causing the support rod 315 to move upward. During the upward movement of the support rod 315, the support plate 37 gradually rotates upward until it is flush with the upper surface of the first support seat 31 and the second support seat 32, providing full support for the lower surface of the fabric 5.

[0082] The drive roller 4 and guide roller 6 continue to transport the fabric 5. When the defective position of the fabric 5 is transported to the corresponding position, the drive cylinder 86 drives the marking drive shaft 85 to move toward one side of the fabric 5. The marking sticker 811 gradually approaches and is attached to the fabric. After the marking is completed, the drive cylinder 86 drives the marking drive shaft 85 to reset.

[0083] In this invention, in order to ensure that the camera 11 can still stably acquire and detect images after the movable roller 21 moves, a limiting roller is set between the movable roller 21 and the driving roller 4, so that the position of the fabric 5 located between the limiting roller and the driving roller 4 remains unchanged, which facilitates detection.

[0084] This invention also provides a control method for an intelligent fabric inspection machine with double-sided marking function, comprising the following steps:

[0085] Step 100: The fabric 5 is transported by the drive roller 4 and the guide roller 6;

[0086] Step 200: The camera 11 acquires images of the fabric 5 in real time and analyzes whether there are any defects on the fabric surface;

[0087] Step 300: When there are defects on the fabric surface, analyze the location and end face of the defects;

[0088] Step 400: Based on the analysis results, the fabric 5 is driven by the set of movable rollers 21 so that the defective end face of the fabric 5 is close to the marking device 8.

[0089] Step 500: Label the defect locations on the fabric 5 using the marking device 8.

[0090] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
