Description

Technical Field

[0001] The present invention relates to the technical field of sock quality inspection, and particularly to a visual inspection device for defects of functional socks. Background Art

[0002] Functional socks are a kind of health product that combines technology and medical principles. According to their use performance and purposes, functional socks can be roughly divided into sports socks, health care socks, antibacterial and odor-proof socks, warm socks, slimming socks, etc. According to different types of functional socks, their production raw materials are also different. For example, cotton is the most common and widespread raw material for sock production, which is sweat-absorbent, breathable, soft and warm, and durable and comfortable; mercerized cotton has better gloss, smoother hand feel, and is less prone to wrinkling, and is suitable for summer. After the production of functional socks is completed, it is necessary to detect them to avoid defective products from flowing out.

[0003] In the prior art, there is an auxiliary device for visual testing in sock production with the publication number of CN118010742B. This auxiliary device is a sock sleeve support with an airbag structure. Based on the inflation and deflation of the sock sleeve support, it is convenient to realize the sleeving of socks. At the same time, the sock sleeve support is arranged in the material channel and can be moved to the follower plate, and based on the follower plate, the appearance test can be carried out on the lower visual inspection line body of the socks.

[0004] Although the above device is convenient for taking and placing socks during the detection process, there are still some defects in the actual detection process. Since there is no automatic blanking function on this visual test auxiliary device, after the visual inspection is completed, workers still need to take the socks out of the auxiliary device, and then place the defective and qualified socks separately. In this process, workers need to watch a machine to distinguish between qualified and unqualified socks. However, by manually taking socks for distinction, it is inevitable that there will be phenomena of misplacement or misrecording, and it is easy to have the phenomenon of defective products flowing out, which affects the production quality of functional socks and greatly reduces the convenience performance of the device.

[0005] Therefore, a visual inspection device for defects of functional socks is proposed to solve the above problems. Summary of the Invention

[0029] Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0030] Such as Figures 1-9The visual inspection device for functional socks defects shown in the figure comprises an inspection box 1, and a production line 2 arranged in the inspection box 1 for conveying functional socks. The production line 2 is mainly a chain plate conveyor line. After the functional socks are produced, they can be conveyed to the inspection box 1 through the production line 2, and the socks board 6 with the socks taken off will be conveyed back. The conveying mode of the production line 2 is intermittent conveying. The dwelling time is not only convenient for the visual inspection mechanism 3 to take pictures of the functional socks, but also convenient for taking the functional socks off the socks board 6. The inspection box 1 is provided with a visual inspection mechanism 3 for detecting functional socks defects. The visual inspection mechanism 3 mainly detects the defects of the functional socks by setting relative The machine and the exposure lamp perform automatic detection. The functional socks pass through each exposure lamp and camera in turn through the sock plate 6. First, they are exposed by the exposure lamp, then the camera takes pictures, and finally the pictures are transmitted to the inside of the information box for analysis. The data analyzed by the information box will be displayed on the display, and then transmitted to the inside of the visual detection device through the data transmission module. Then, the result is obtained through calculation, and an alarm is issued through the sound and light alarm. At the same time, the signal instruction is transmitted to the upper electric telescopic cylinder 8 that needs to be started through the controller, so that when the unqualified or qualified functional socks reach the U-shaped plate 11 in the future, the functional socks can be automatically taken off;

[0031] A plurality of fixed seats 4 are equidistantly fixedly connected to the top of the conveyor belt of the production line 2, and a plurality of fixed seats 4 are provided with sock plates 6. A pair of unloading platforms 7 are fixedly connected to the rear side of the production line 2. An upper electric telescopic cylinder 8 is fixedly connected to the bottom end of the frame of the production line 2 and the corresponding position to the unloading platform 7. A rectangular frame 9 is slidably connected to the outer wall of the unloading platform 7. The output end of the upper electric telescopic cylinder 8 is fixedly connected to the side wall of the rectangular frame 9. A connecting rod 10 is fixedly connected to the front side of the rectangular frame 9. The top of the connecting rod 10 is rotatably connected to a U-shaped plate 11 for pushing out functional socks through a torsion spring. A round rod 12 is slidably connected to the top of the connecting rod 10. A transverse groove 14 is provided at the top of the unloading platform 7. An upper straight groove 13 and a lower straight groove 15 are respectively provided at both ends of the transverse groove 14. An inclined groove 16 is provided between the lower straight groove 15 and the upper straight groove 13. An inward groove 17 is provided at the end of the upper straight groove 13 away from the lower straight groove 15. A flipping mechanism for flipping the sock plate 6 is also provided.

[0032] The flipping mechanism includes a cylinder 5. There are several cylinders 5, and several cylinders 5 are all rotatably connected to the inside of the fixed seat 4. The sock boards 6 are all fixedly connected to the top ends of the outer walls of the cylinders 5. A quarter spiral-shaped spiral groove 23 is provided inside the cylinder 5. The side walls of the fixed seat 4 are all penetrated and slidably connected with a moving plate 24. A top rod 25 is fixedly connected to the bottom end of the moving plate 24, and the bottom of the top rod 25 is inserted into the inside of the spiral groove 23. A bottom rod 26 is fixedly connected to the bottom of the moving plate 24 and on the side away from the top rod 25. A straight plate 27 is fixedly connected to the side wall of the rectangular frame 9 and the straight plate 27 is arranged inside the frame of the production line 2 in a penetrating manner. The front side of the straight plate 27 is inclined. The top end of the straight plate 27 is flush with the top end of the bottom rod 26, and the inclined surface of the straight plate 27 is arranged on the front side of the U-shaped plate 11;

[0033] A scroll spring 28 is provided inside the cylinder 5. Through the setting of the scroll spring 28, it is convenient to drive the cylinder 5 to flip and reset. One end of the scroll spring 28 is fixedly connected to the inside of the cylinder 5, and the other end of the scroll spring 28 is fixedly connected to the side wall of the fixed seat 4. A top plate 29 is fixedly connected to the top end of the moving plate 24, and a lower spring 30 is fixedly connected between the side wall of the top plate 29 and the side wall of the fixed seat 4. Through the setting of the lower spring 30, it is convenient to push the moving plate 24 to reset;

[0034] During the process of defect detection of functional socks, workers sequentially put the produced functional socks on the sock boards 6. Under the transportation of the production line 2, the functional socks pass through the visual detection mechanism 3 in the detection box 1 for defect detection. Subsequently, the detected functional socks are transported to the side of the blanking table 7. When the visual detection mechanism 3 detects that the functional socks have defects, it will send a signal to the upper electric telescopic cylinder 8 corresponding to the material box 39. Then, when the defective functional socks move to the side of the material box 39, the production line 2 stops running, and the corresponding upper electric telescopic cylinder 8 will start to pull the rectangular frame 9 to move on the blanking table 7, thereby driving the straight plate 27 to slide. Subsequently, when the front end of the straight plate 27 moves to the side of the bottom rod 26, the inclined surface of the straight plate 27 will gradually squeeze the bottom rod 26 to slide, thereby driving the moving plate 24 to slide towards the inside of the cylinder 5, gradually compressing the lower spring 30, and driving the top rod 25 to move in the spiral groove 23. Furthermore, since the moving plate 24 is restricted to only slide left and right, under the action of the spiral groove 23 squeezed by the top rod 25, the cylinder 5 will be driven to rotate, thereby driving the sock board 6 to flip forward. Subsequently, the bottom rod 26 moves out of the inclined surface of the straight plate 27 and moves to the side wall of the straight plate 27, and the side wall of the straight plate 27 keeps squeezing the bottom rod 26. During this process, since one end of the scroll spring 28 is fixed to the inside of the cylinder 5 and the other end is fixed to the side wall of the fixed seat 4, when the cylinder 5 rotates, the scroll spring 28 will be gradually compressed.

[0035] The bottom end of the round rod 12 is inserted into the inner side of the groove 17. The connection between the groove 17 and the upper straight groove 13 is inclined, which is convenient for the round rod 12 to slide out of the groove 17 and makes there be a step between the groove 17 and the inclined groove 16 to limit the sliding position of the round rod 12. The bottom end of the round rod 12 is set as a smooth arc surface, which is further convenient for the round rod 12 to slide out of the groove 17. A upper spring 18 is fixedly connected between the outer wall of the round rod 12 and the top of the connecting rod 10. At the top of the connecting rod 10 and behind the U-shaped plate 11, a positioning block 42 for limiting is fixedly connected. The upper spring 18 is convenient for pushing the bottom end of the round rod 12 into the groove 17. A chute 19 is opened on the side wall of the rectangular frame 9. A slider 20 is fixedly connected to the side wall of the connecting rod 10 and inside the chute 19. A return spring 21 is fixedly connected between the inside of the chute 19 and the slider 20. The return spring 21 is convenient for pulling the slider 20 and the connecting rod 10 to reset, and then driving the U-shaped plate 11 to quickly insert into the sock board 6;

[0036] When the upper electric telescopic cylinder 8 pulls the rectangular frame 9 to slide, it will drive the connecting rod 10 and the U-shaped plate 11 to move simultaneously, and drive the round rod 12 to slide out of the inclined surface in the groove 17 (since there is a step between the groove 17 and the inclined groove 16 to be restricted, the round rod 12 cannot slide into the inclined groove 16). At the same time, the upper spring 18 is stretched upward. Then the round rod 12 slides into the upper straight groove 13. When the straight plate 27 presses the sock board 6 to turn 90 degrees, the round rod 12 slides to the connection between the upper straight groove 13 and the transverse groove 14, and then releases the restriction on the sliding positions of the connecting rod 10 and the slider 20. Then, under the elastic force of the return spring 21, the slider 20 is pulled to reset, and at the same time, the connecting rod 10, the U-shaped plate 11 and the round rod 12 are driven to slide. At the same time, the round rod 12 slides through the transverse groove 14 into the lower straight groove 15, and the U-shaped plate 11 is driven to insert into the outside of the sock board 6. Since the rear side of the U-shaped plate 11 is restricted by the positioning block 42 and cannot rotate backward, then under the continuous drive of the upper electric telescopic cylinder 8, the U-shaped plate 11 will be driven to move forward to take off the functional sock on the sock board 6, and at the same time, the round rod 12 is driven to slide in the lower straight groove 15. Then the taken-off functional sock falls into the material box 39;

[0037] Then, the upper electric telescopic cylinder 8 can be controlled to reset, which will drive the rectangular frame 9, the straight plate 27, the connecting rod 10 and the U-shaped plate 11 to reset. When the U-shaped plate 11 moves to the end of the sock plate 6, the round rod 12 will also slide to the rear end of the lower straight groove 15, and then the round rod 12 slides into the inclined groove 16 (at this time, the reset spring 21 pulls the slider 20 under its elastic force to ensure that the round rod 12 does not slide into the horizontal groove 14). Furthermore, it squeezes the round rod 12 and the connecting rod 10 to move, drives the slider 20 to slide inside the chute 19, and gradually stretches the reset spring 21. During this process, since the U-shaped plate 11 slides to the end of the sock plate 6 and is blocked, and there is no restriction on the front side of the U-shaped plate 11, the U-shaped plate 11 will be driven to rotate around the hinge under the pulling force and compress the torsion spring. Subsequently, the U-shaped plate 11 moves out of the sock plate 6 and releases the extrusion on the U-shaped plate 11. Then, it is pulled back under the elastic force of the torsion spring. At the same time, the inclined surface on the straight plate 27 moves beside the lower rod 26, and then gradually releases the extrusion on the moving plate 24. Subsequently, the cylinder 5 is pushed to flip and reset under the elastic force of the volute spring 28. Then, the round rod 12 slides out of the inclined groove 16 and into the upper straight groove 13 and is located above the groove 17. Subsequently, the bottom end of the round rod 12 is pushed into the groove 17 under the elastic force of the upper spring 18. In this way, the automatic taking-off and putting-on of the functional sock is realized repeatedly. When the qualified functional sock moves beside the conveying mechanism 36, the controller will control the corresponding upper electric telescopic cylinder 8 to start and repeat the above operations to take off the sock.

[0038] To ensure the normal operation of the device, upper touch sensors 22 are fixedly connected through the bottoms at both ends of the horizontal groove 14. The upper touch sensors 22 are electrically connected to the upper electric telescopic cylinder 8 through the controller. The upper electric telescopic cylinder 8 is electrically connected to the visual detection mechanism 3 through the controller. Since it takes a certain amount of time for the round rod 12 to slide in the horizontal groove 14, when the round rod 12 slides in the horizontal groove 14, if the upper electric telescopic cylinder 8 continues to drive, it will be blocked, and it is easy to damage the upper electric telescopic cylinder 8 after a long time. Therefore, the upper touch sensors 22 are respectively arranged at both ends of the horizontal groove 14 to control the start and stop of the upper electric telescopic cylinder 8, and during the reset process, a single trigger of one upper touch sensor 22 can be set not to work at a certain degree.

[0039] To improve the stability of the device, a quarter-circular limiting groove 32 is opened inside the fixed seat 4. A limiting rod 31 is fixedly connected to the side wall of the cylinder 5, and the limiting rod 31 is slidably connected inside the limiting groove 32. Through the arrangement of the limiting rod 31 and the limiting groove 32, the rotation position of the cylinder 5 can be limited, avoiding the cylinder 5 rotating randomly under the elastic force of the volute spring 28 and improving the stability during the operation of the device.

[0040] In order to collect more defective functional socks, a notch 33 is provided at the front side of the frame of production line 2 corresponding to the blanking table 7. A conveying frame 34 and a placing table 35 are respectively provided at the front side of production line 2 and below the notch 33. A conveying mechanism 36 for conveying qualified functional socks is provided on the conveying frame 34. A side plate 37 is fixedly connected to the top of the placing table 35. A sliding seat 38 is slidably connected to the top of the placing table 35. A material box 39 is placed inside the sliding seat 38. A lower electric telescopic cylinder 40 is fixedly connected to the side wall of the side plate 37. The output end of the lower electric telescopic cylinder 40 passes through the side plate 37 and is fixedly connected to the side wall of the sliding seat 38. A lower touch sensor 41 is fixedly connected through the top of the placing table 35 and away from one side of the side plate 37. The lower touch sensor 41 is electrically connected to the lower electric telescopic cylinder 40 through a controller;

[0041] While the controller controls the upper electric telescopic cylinder 8 to start, it will also control the lower electric telescopic cylinder 40 to start, thereby pushing the sliding seat 38 to move a fixed distance on the placing table 35 and driving the material box 39 to move a certain distance. Thus, the blanking position inside the material box 39 can be changed to ensure that the removed functional socks can evenly fall into the material box 39, avoiding the situation where defective products of functional socks accumulate in one place and requiring workers to regularly organize the functional socks in the material box 39, further improving the convenience performance of the device. Here, it should be noted that the moving distance of the lower electric telescopic cylinder 40 can be controlled by program setting each time. And when the material box 39 moves to the other end of the placing table 35, the material box 39 will touch the lower touch sensor 41. Then, the lower touch sensor 41 transmits a signal to the controller, and the controller controls the lower electric telescopic cylinder 40 to reset. Repeating this way can ensure that defective functional socks are evenly collected in the material box 39.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention.

[0043] Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
