[0020] like Figures 1 to 12 As shown, a device for detecting flying yarns on the surface of a ribbon comprises: a detection box 1 and a ribbon 2; further comprising: a first placement portion 3, which is arranged on the detection box 1; a movable support portion, which is opened on the detection box 1 to limit the movement of other components; a second placement portion 4, which is arranged on the detection box 1, moves on the movable support portion, and cooperates with the first placement portion 3; the second placement portion 4 comprises: a first driving member, which is arranged on the movable support portion; a second placement member, which is arranged on the detection box 1 and connected to the first driving member, so that under the action of the first driving member, it is close to or away from the first placement portion 3 to facilitate the installation and placement of the ribbon 2; a detection portion 5, which is arranged on the detection box 1 , and moves on the movable support part to perform visual inspection on the webbing 2; the inspection part 5 includes: a detection plate 501, which moves on the inspection box 1 through a driving part 7; a detection member, which is arranged on the detection plate 501; a quick return driving member, which is arranged on the detection plate 501 to drive the detection member to reciprocate; a placement stabilization part 6, which is arranged on the detection plate 501 and is at the bottom end of the detection part 5, so as to stably transmit the webbing 2; the driving part 7 is arranged in the inspection box 1, and is connected with the detection plate 501, the placement stabilization part 6 and the second placement part 4, so as to drive the detection plate 501 and the placement stabilization part 6 to move up and down through the movement of the second placement part 4.

[0021] In the embodiment of the present invention, the second placement portion 4 can move along the movable support portion, so that the second placement portion 4 can be close to or away from the first placement portion 3, so that when placing the webbing 2, the second placement portion 4 can be moved to the position closest to the first placement portion 3, and the other end of the webbing 2 can be fixed on the second placement portion 4, and the second placement portion 4 can be moved to the position away from the first placement portion 3 during detection. In this process, the placement stabilization portion 6 will support the position of the webbing 2 to be detected to facilitate visual detection of the position, thereby simplifying the process of placing the webbing 2 and making it more convenient; when moving the webbing 2, the webbing 2 is detected by arranging a detection portion 5 directly above the position of the webbing 2 to be detected, and a quick return drive is provided to make the detection member move synchronously with the moving webbing 2, so that the detection member and the portion 5 to be detected of the webbing 2 remain stationary, thereby improving the visual detection accuracy of the detection member.

[0022] like Figures 1 to 3As shown, the first placement portion 3 includes: a first rotating shaft 301, which is arranged on the inner wall of the detection box 1; a first limiting disc 302, which is sleeved on the first rotating shaft 301 to limit the webbing 2; a first placement roller 303, which is connected to one end of the first rotating shaft 301 to place the webbing 2 by winding; a first limiting plate 304, one end of which is connected to the first limiting disc 302, and the other end is connected to the first placement roller 303 via a first bolt 305 to fix one end of the webbing 2.

[0023] In the embodiment of the present invention, the webbing 2 is rolled up on the first placement roller 303, and one end of the webbing 2 is between the first placement roller 303 and the first limiting plate 304. The first limiting plate 304 is then squeezed and deformed by rotating the first bolt 305, so that one end of the webbing 2 is fixed. A first limiting disc 302 is provided to limit the webbing 2 to ensure that the webbing 2 is rolled flat to facilitate subsequent rotation along the first placement roller 303. When the second placement roller 405 pulls the webbing 2, the first placement roller 303 is driven to rotate through the webbing 2, and the first placement roller 303 drives the first rotating shaft 301 to rotate, thereby achieving rotation stability.

[0024] like Figures 4 to 5 As shown, the movable support portion includes: a transverse groove 101, which is opened on the outer surface of the detection box 1; a placement plate 102, which is arranged on the inner wall of the detection box 1 and is flush with the bottom end of the transverse groove 101 to place the first driving member; a first vertical groove 103, which is opened on the detection box 1 and is located at the top end of the transverse groove 101 to limit the movement of the detection portion 5; a second vertical groove 104, which is opened on the detection box 1 and is located at the bottom end of the transverse groove 101 to limit the movement of the placement stabilization portion 6.

[0025] like Figures 4 to 7 As shown, the second placement member includes: a first sliding block 402, which slides in the transverse groove 101, and a second motor is placed in the first sliding block 402; a first rack 403, which is arranged on the first sliding block 402 and connected to the driving unit 7; a second placement roller 405, which is connected to the output end of the second motor; a second limiting disc 404, which is arranged on the second placement roller 405 close to one end of the first sliding block 402; a second limiting plate 406, one end of which is connected to the second limiting disc 404, and the other end is connected to the second placement roller 405 via a second bolt 407 to fix one end of the webbing 2.

[0026] In the embodiment of the present invention, by providing a transverse groove 101, when placing the webbing 2, after one end of the webbing 2 is fixed on the first placement portion 3, the other end of the webbing 2 is placed between the second placement roller 405 and the second limiting plate 406. At this time, the second limiting plate 406 is squeezed and deformed by the second bolt 407 to fix this end of the webbing 2; then the cylinder 401 is started to drive the first sliding block 402 to move along the transverse groove 101 in the direction away from the first placement roller 303, thereby driving the webbing 2 to move in the direction away from the first placement roller 303. In this process, the first placement roller 303 will be driven to rotate. At the same time, after the second placement roller 405 moves to the other end, the detection portion 5 and the placement stabilization portion 6 will also move to the specified position under the action of the driving portion 7.

[0027] The first rack 403 is connected to the driving part 7 , thereby driving the detection part 5 and the placement stabilization part 6 to slide up and down along the first vertical groove 103 and the second vertical groove 104 respectively.

[0028] like Figures 4 to 9 As shown, the driving part 7 includes: a second rotating shaft 701, which is arranged on the inner wall of the detection box 1; a first gear 702, which is sleeved on the second rotating shaft 701 and meshed with the first rack 403; a second gear 703, which is sleeved on the second rotating shaft 701 and is located on one side of the first gear 702; a first connecting member, one end of which is connected to the second gear 703, and the other end is connected to the detection part 5, so as to drive the detection plate 501 to move up and down; a second connecting member, one end of which is connected to the second gear 703, and the other end is connected to the placement stabilization part 6, so as to drive the placement stabilization part 6 to move up and down.

[0029] like Figures 7 to 9 As shown, the first connecting member includes: a second limiting guide rail 705, which is arranged inside the detection box 1, and its two ends are fixedly connected to the upper and lower ends of the detection box 1; a third rack 708, which slides on the second limiting guide rail 705, and the third rack 708 is meshingly connected with the second gear 703; a second L-shaped connecting shaft 709, one end of which is fixedly connected to an end of the third rack 708 away from the teeth, and the other end is passed through the first vertical groove 103 and connected to the detection plate 501, and the second L-shaped connecting shaft 709 slides in the first vertical groove 103.

[0030] like Figures 7 to 9As shown, the second connecting member includes: a first limiting guide rail 704, which is arranged inside the detection box 1, and its two ends are fixedly connected to the upper and lower ends of the detection box 1; a second rack 706, which slides on the second limiting guide rail 705, and the third rack 708 is meshed and connected with the second gear 703; a first L-shaped connecting shaft 707, one end of which is fixedly connected to one end of the second rack 706 close to the tooth, and the other end is passed through the second vertical groove 104 and connected to the placement stabilization part 6, and the first L-shaped connecting shaft 707 slides in the second vertical groove 104.

[0031] In the embodiment of the present invention, when the first sliding block 402 moves along the transverse groove 101 in the direction away from the first placement portion 3, the first rack 403 on the first sliding block 402 will be meshed and connected with the first gear 702, thereby driving the first gear 702 to rotate, and the rotation of the first gear 702 will drive the second gear 703 to rotate through the second rotating shaft 701; the rotation of the second gear 703 will drive the third rack 708 to move downward along the second limiting guide rail 705, and the third rack 708 will drive the second L-shaped connecting shaft 709 to move downward, thereby driving the detection plate 501 to move downward, so as to reach the designated position to detect the webbing 2 to be detected; and the detection plate 501 will block the left and right movement of the second placement portion 4 when it is at the designated position, so that it is designed to be able to move up and down, so as to facilitate the placement of the webbing 2 without affecting the position of the detection equipment.

[0032] When the second gear 703 rotates, it will also drive the second rack 706 to move upward along the first limiting guide rail 704. The second rack 706 will drive the first L-shaped connecting shaft 707 to move upward along the second vertical groove 104, thereby driving the placement stabilization part 6 to move upward, stabilizing the webbing 2 at the position to be detected. Because the second rack 706 and the third rack 708 both engage and move with the second gear 703, the placement stabilization part 6 and the detection part 5 move toward or oppositely at the same time.

[0033] The placement stabilizing member includes: a support plate 601 connected to the other end of the first L-shaped connecting shaft 707, and two connecting rollers 602 are arranged at both ends of the support plate 601, contacting the webbing 2 to support and change the position of the webbing 2.

[0034] like Figures 9 to 12 As shown, the detection component includes: a first limiting groove 503, which is opened on the detection plate 501; a second sliding block 502, which slides in the first limiting groove 503; two cameras 511 are provided, and the two cameras 511 are provided at both sides of the bottom end of the second sliding block 502; a first limiting shaft 504, which is provided on the second sliding block 502 and is connected to the quick-return driving component.

[0035] like Figures 9 to 12 As shown, the quick-return drive member includes: a first motor 507, which is arranged on the detection plate 501; a rotating disk 508, which is arranged at the top of the detection plate 501 and is connected to the output end of the first motor 507; a first rotating slider 509, which is rotatably connected to the upper end of the rotating disk 508; a first fixed shaft 505, which is arranged at the top of the detection plate 501; a rotating plate 506, one end of which is rotatably connected to the first fixed shaft 505; a second limiting groove 510, which is opened on the rotating plate 506, and the first rotating slider 509 slides in the second limiting groove 510; a second rotating slider 512, which is arranged at the other end of the rotating plate 506, is rotatably connected to the rotating plate 506, and the second rotating slider 512 slides in the first limiting shaft 504.

[0036] In the embodiment of the present invention, after the position of the second placement portion 4 is restored to the detection position, when the webbing 2 is detected, the second motor is first started to drive the second placement roller 405 to rotate, so that the second placement roller 405 drives the webbing 2 to move around the second placement roller 405, and the other end drives the first placement roller 303 to rotate, and the webbing 2 will continuously move through the detection portion 5 and be detected by the detection portion 5; in this process, the first motor 507 is started to drive the rotating disk 508 to rotate, and the rotating disk 508 drives the first rotating slider 509 to rotate, so that the first rotating slider 509 moves along the rotating plate 506. The second limiting groove 510 moves, thereby driving the rotating plate 506 to rotate around the first fixed axis 505. At the same time, the movement of the other end of the rotating plate 506 will drive the second rotating slider 512 to move along the first limiting axis 504, and at the same time drive the second sliding block 502 to move along the first limiting groove 503, finally making the two cameras 511 on the second sliding block 502 move at the same time. At this time, the moving speed of the camera 511 and the moving speed of the ribbon 2 remain stationary, thereby ensuring the clarity of the picture taken by the camera 511, and can increase the moving speed of the ribbon 2, thereby improving the detection efficiency.

[0037] Among them, after the rotating plate 506 rotates to one end, it will move in the opposite direction under the action of the first rotating slider 509, thereby forming a reciprocating movement, so that the rotating plate 506 drives the first slider to move back and forth, that is, drives the camera 511 to move back and forth. When the direction of the reciprocating movement is the same as the moving direction of the ribbon 2, the camera 511 works normally. When the direction of the reciprocating movement is opposite to the moving direction of the ribbon 2, the picture taken by the camera 511 is not recorded in the detection system, thereby avoiding blurred images; at the same time, two cameras 511 are set to shoot a larger range, and the pictures taken in the two adjacent periods when the camera 511 and the ribbon 2 remain stationary have a certain degree of sufficiency, so that during the invalid time when the camera 511 moves in the opposite direction, the length moved by the ribbon 2 is also captured, thereby avoiding missed detection.

[0038] The present invention also provides a detection method applicable to the above-mentioned ribbon surface flying yarn detection device, comprising the following steps: S1, start the cylinder 401 to drive the first slider to move to the position of the transverse groove 101 closest to the first placement portion 3; S2, roll the ribbon 2 onto the first placement roller 303, and fix the inner end of the ribbon 2 onto the first limit plate 304, then move the other end of the ribbon 2 to the second placement roller 405 and fix it onto the second limit plate 406; S3, start the cylinder 401 again to move the first slider to the position of the transverse groove 101 farthest from the first placement portion 3. At this time, under the action of the driving portion 7, the placement stabilizing portion 6 is driven to be supported at the lower end of the ribbon 2, and the detection portion 5 is just at the top of the ribbon 2, so as to facilitate the detection of the ribbon 2; S4. During detection, the second motor is started to drive the second placement roller 405 to rotate, so that the ribbon 2 moves from the first placement roller 303 to the second placement roller 405. At the same time, the first motor 507 is started to drive the quick-return drive member to rotate, so that the quick-return drive member drives the detection member to move, thereby driving the camera 511 to move, so that the camera 511 and the moving ribbon 2 remain stationary, thereby ensuring the accuracy of visual detection and finally completing the detection.

[0039] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
