Description

Technical Field

[0002] Functional socks are a kind of health product that combines science and technology with medical principles. According to their performance and purpose, functional socks can be roughly divided into sports socks, health socks, antibacterial and deodorizing socks, thermal socks and slimming socks. The production materials of different types of functional socks are also different. For example, cotton is the most common and most popular sock production material, which is sweat-absorbent and breathable, soft and warm, durable and comfortable; mercerized cotton has better gloss, smoother feel, and is not easy to wrinkle, which is suitable for summer. After the functional socks are produced, they need to be tested to avoid defective products from flowing out.

[0003] In the prior art, there is an auxiliary device for visual testing of socks production with publication number CN118010742B. The auxiliary device is a sock bracket with an airbag structure.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figure 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; 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 provided on the rectangular frame 9. The turning mechanism includes a cylinder 5, and a plurality of cylinders 5 are provided. The plurality of cylinders 5 are rotatably connected to the inner side of the fixed seat 4, and the sock plates 6 are fixedly connected to the top of the outer wall of the cylinder 5. A quarter-spiral spiral groove 23 is provided on the inner side of the cylinder 5. The side walls of the fixed seat 4 are penetrated by a movable plate 24 which is slidably connected. An upper rod 25 is fixedly connected to the bottom end of the movable plate 24. The bottom of the upper rod 25 is inserted into the inner side of the spiral groove 23. A lower rod 26 is fixedly connected to the bottom of the movable plate 24 and away from the side of the upper 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 on the inner side of the frame of the production line 2. The front side of the straight plate 27 is arranged obliquely, and the top of the straight plate 27 is flush with the top of the lower rod 26, and the inclined surface of the straight plate 27 is arranged on the front side of the U-shaped plate 11. A volute spring 28 is provided inside the cylinder 5. The volute spring 28 is provided to facilitate driving the cylinder 5 to flip and reset. One end of the volute spring 28 is fixedly connected to the inside of the cylinder 5, and the other end of the volute spring 28 is fixedly connected to the side wall of the fixed seat 4. A top plate 29 is fixedly connected to the top of the movable plate 24. 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. The lower spring 30 is provided to facilitate pushing the movable plate 24 to reset. During the defect detection process of functional socks, workers put the produced functional socks on the sock plate 6 in turn, and the functional socks are transported by the production line 2 to the visual inspection mechanism 3 in the inspection box 1 for defect detection. Then, the functional socks after the inspection are transported to the side of the unloading table 7. When the visual inspection mechanism 3 detects that the functional socks have defects, it will transmit a signal to the upper electric telescopic cylinder 8 corresponding to the material box 39. Then, when the functional socks with defects 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 unloading table 7, thereby driving the straight plate 27 to slide. Then, when the front end of the straight plate 27 moves to the side of the lower rod 26, the straight plate 27 is inclined. The surface will gradually squeeze the lower rod 26 to slide, thereby driving the movable plate 24 to slide toward the inside of the cylinder 5, and gradually compressing the lower spring 30, and driving the upper rod 25 to move in the spiral groove 23. Since the movable plate 24 is restricted and can only slide left and right, the cylinder 5 will be driven to rotate under the action of the squeezing spiral groove 23 of the upper rod 25, thereby driving the sock plate 6 to flip forward, and then the lower rod 26 moves out of the inclined surface of the straight plate 27 to the side wall of the straight plate 27, and keeps squeezing the lower rod 26 through the side wall of the straight plate 27. In this process, since one end of the volute 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, the volute spring 28 will be gradually compressed when the cylinder 5 rotates.

[0021] The bottom end of the round rod 12 is inserted into the inner side of the groove 17, and 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 a step is provided 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. An upper spring 18 is fixedly connected between the outer wall of the round rod 12 and the top of the connecting rod 10. A positioning block 42 for limiting the position is fixedly connected to the top of the connecting rod 10 and located at the rear side of the U-shaped plate 11. The upper spring 18 is convenient for pushing the bottom end of the round rod 12 into the groove 17. A sliding groove 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 located inside the sliding groove 19. A reset spring 21 is fixedly connected between the inner side of the sliding groove 19 and the slider 20. The reset spring 21 is convenient for pulling the slider 20 and the connecting rod 10 to reset, thereby driving the U-shaped plate 11 to quickly insert into the sock plate 6; 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 at the same time, and drive the round rod 12 to slide out from the inclined surface in the groove 17 (due to the step between the groove 17 and the inclined groove 16, the round rod 12 cannot slide into the inclined groove 16), and at the same time stretch the upper spring 18 upward, and then the round rod 12 slides into the upper straight groove 13, and then when the straight plate 27 squeezes the sock plate 6 and flips 90 degrees, the round rod 12 slides to the connection between the upper straight groove 13 and the horizontal groove 14, thereby releasing the restriction on the sliding position of the connecting rod 10 and the slider 20, and then Under the elastic force of the reset 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, and at the same time, the round rod 12 is driven to slide 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 plate 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 continued driving of the upper electric telescopic cylinder 8, the U-shaped plate 11 will be driven to move forward, and the functional socks on the sock plate 6 will be taken off, and at the same time, the round rod 12 will be driven to slide in the lower straight groove 15, and the functional socks taken off will fall into the material box 39; 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 will slide into the inclined groove 16 (at this time, the slider 20 is pulled under the elastic force of the reset spring 21 to ensure that the round rod 12 does not slide into the horizontal groove 14), thereby squeezing the round rod 12 and the connecting rod 10 to move, and driving the slider 20 to slide on the inside of the slide groove 19, and gradually stretching the reset spring 21. In this process, since the U-shaped plate 11 slides to the end of the sock plate 6 and is hindered, and there is no restriction on the front side of the U-shaped plate 11, it will drive the U-shaped plate 1 under the action of tension. 1 rotates around the hinge and compresses the torsion spring, then the U-shaped plate 11 moves out from the sock plate 6 and releases the squeezing of the U-shaped plate 11, and then it is pulled back to its original position under the elastic force of the torsion spring, and at the same time the inclined surface on the straight plate 27 moves to the side of the lower rod 26, and then the squeezing of the movable plate 24 is gradually released, and then the cylinder 5 is pushed to flip and reset under the elastic force of the spiral spring 28, and then the round rod 12 slides out of the inclined groove 16 and slides into the upper straight groove 13, and is located above the groove 17, and then the bottom end of the round rod 12 is pushed into the groove 17 under the elastic force of the upper spring 18, and the functional socks are automatically removed repeatedly in this way. When the qualified functional socks move to the side of the conveying mechanism 36, the controller will control the corresponding upper electric telescopic cylinder 8 to start and repeat the above operation to remove the socks.

[0022] In order to ensure the normal operation of the device, upper touch sensors 22 are fixedly connected to the bottom of both ends of the transverse groove 14. The upper touch sensor 22 is electrically connected to the upper electric telescopic cylinder 8 through the controller, and 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 transverse groove 14, when the round rod 12 slides in the transverse groove 14, if the upper electric telescopic cylinder 8 continues to drive, it will be hindered, which may easily cause damage to the upper electric telescopic cylinder 8 for a long time. Therefore, upper touch sensors 22 are respectively arranged at both ends of the transverse groove 14 to control the start and stop of the upper electric telescopic cylinder 8, and during the reset process, a single triggering of an upper touch sensor 22 can set the program not to work.

[0023] In order to improve the stability of the device, a quarter-circular limiting groove 32 is opened on the inner side of the fixed seat 4, and the side wall of the cylinder 5 is fixedly connected to the limiting rod 31, and the limiting rod 31 is slidably connected to the inner side of the limiting groove 32. Through the setting of the limiting rod 31 and the limiting groove 32, the rotation position of the cylinder 5 can be limited to prevent the cylinder 5 from rotating freely under the elastic force of the spiral spring 28, thereby improving the stability of the device during operation.

[0024] In order to collect more functional socks with defects, a notch 33 is provided on the front side of the frame of the production line 2 and at a position corresponding to the unloading platform 7. A conveying frame 34 and a placing platform 35 are provided on the front side of the 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 platform 35. A sliding seat 38 is slidably connected to the top of the placing platform 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 to the top of the placing platform 35 and away from the side plate 37. The lower touch sensor 41 is electrically connected to the lower electric telescopic cylinder 40 through a controller. When 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 placement table 35, and driving the material box 39 to move a certain distance, thereby changing the unloading position in the material box 39, ensuring that the taken-off functional socks can fall evenly into the material box 39, avoiding the situation where defective functional socks are piled up in one place, and workers are required to sort out the functional socks in the material box 39 regularly, further improving the convenience of the device. It should be noted here that the moving distance of the lower electric telescopic cylinder 40 can be controlled by program settings each time, and when the material box 39 moves to the other end of the placement table 35, the material box 39 will touch the lower touch sensor 41, and then the lower touch sensor 41 will transmit the signal to the controller, and the controller controls the lower electric telescopic cylinder 40 to reset, and so on and so forth, ensuring that the defective functional socks are evenly collected in the material box 39.
