Description

Technical Field

[0001] The invention relates to the technical field of coil detection and marking, and in particular to an automatic coil reel detection and bad position marking device. Background Art

[0002] Coils are usually shipped in the form of rolled materials. In the past, the appearance quality inspection of coils relied on manual visual inspection. In order to improve the inspection accuracy, the existing technology uses quality inspection cameras to inspect the appearance quality of the coils, and then marks them with marking pens. However, the coils need to be reeled and unreeled when being inspected. When reeling, the material wrapped on the coil to be released will be pulled. If it is necessary to stop for marking, the coil to be released will continue to rotate due to inertia, releasing more coils. The inspected position of the coil cannot remain flat, affecting the quality inspection of the coil. Moreover, the marking pen can only be used to mark the upper and lower sides of the coil. After the coil is rolled up, the marked position is hidden, and the rolled coil cannot locate the defective position. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an automatic winding and unwinding roll detection and bad position marking device. When the coil to be released rotates, there is friction, which prevents the coil from being released too much due to inertia after the pulling of the coil stops, and the friction is smaller when the coil to be released is heavier, so that the coil can be pulled and released without a large power. After the coil releases more material, its own gravity becomes smaller, and the friction is increased at this time. The pulling force on the coil remains unchanged, so the coil can be stably pulled and released. The coil flattening mechanism is used to keep the coil flat when it is detected, which is conducive to accurate detection of the coil, and the bad position is marked by sticking labels on the upper and lower sides of the edge of the coil. The bad position of the coil can be known without unfolding the rolled coil, which is convenient for the subsequent rapid processing of the bad position, and can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic reeling and unwinding detection and bad position marking device, comprising a reeling and unwinding mechanism, the reeling and unwinding mechanism comprising a base and a reeling motor, the rear left end of the reeling and unwinding mechanism is fixedly connected to a left support, the rear right end of the reeling and unwinding mechanism is fixedly connected to a right support, the middle part of the left support is provided with a vertical groove, a vertical support block is vertically slidably connected in the vertical groove, the bottom of the vertical groove is connected to the bottom of the vertical support block through a gravity follower component, the vertical support block and the right support are respectively rotatably connected with end shafts, the front ends of the two end shafts are respectively fixedly connected to the rear middle parts of two coil sleeves, each coil sleeve is respectively installed with a sleeve concentric tightening mechanism, and the rear end of the end shaft on the right support is fixedly connected to the reeling motor;

[0005] It also includes an adjustable coil friction release mechanism and a coil flattening mechanism, wherein the adjustable coil friction release mechanism is installed on the top of the left support, the coil flattening mechanism is installed between the right support and the left support, and a coil reel rear end alignment mechanism is installed on the coil flattening mechanism, and a coil detection mechanism is installed on the front side of the coil reel rear end alignment mechanism.

[0006] The left coil sleeve is sleeved with a core sleeve for the coil to be inspected, and the right coil sleeve is sleeved with a core sleeve for winding and rewinding the coil. Then the two core sleeves are tightened by the sleeve concentric tightening mechanism to keep the core sleeve and the coil sleeve in a concentric fixed state. The winding motor drives the right coil sleeve to rotate, and the core sleeve on the coil sleeve rotates clockwise to start winding the coil, so as to pull the coil to the right. The coil to be inspected and the coil sleeve on the left rotate clockwise to release the coil. The adjustable coil friction release The mechanism can adjust the friction force of the coil sleeve on the left side when it rotates. Since the coil sleeve on the left side is subject to friction when it rotates, when the winding motor stops working, the coil sleeve on the left side will not continue to rotate due to inertia, avoiding the coil sleeve on the left side from releasing too much coil. The coil to be tested is heavier in the initial testing stage, so it presses the gravity follower component, shortening the gravity follower component, and the vertical support block moves down a short distance along the vertical groove. At this time, the adjustable coil friction release mechanism is effective for the coil sleeve on the left side when it rotates. The resistance is small, and the winding motor does not need a large power to pull the coil sleeve on the left side, so that the coil to be detected on the left coil sleeve is released. As the coil to be detected is released, its gravity becomes smaller, the gravity follow-up component rebounds and extends, and the vertical support block moves up a short distance along the vertical groove. During this process, the adjustable coil friction release mechanism increases the resistance to the rotation of the left coil sleeve, so as to avoid the excessive release of the coil by the winding motor after the gravity of the coil to be detected is reduced. With the help of the gravity follow-up component, the resistance to the rotation of the coil sleeve can be adjusted according to the gravity of the coil to be detected on the left coil sleeve, so as to achieve stable release of the coil by the left coil sleeve. The coil flattening mechanism is located between the tops of the two coil sleeves, and is used to flatten the coil, ensuring that the coil detection mechanism can detect the flat coil and improve the accuracy of the detection. The rear end alignment mechanism of the retractable and unreeling coil can align the rear ends of the core sleeves on the two coil sleeves, ensuring that the rear edge of the coil is kept neat when the core sleeve is wound around the coil.

[0007] Furthermore, the gravity follower assembly includes a gravity follower vertical telescopic rod and a gravity follower spring.

The quality inspection camera is used to inspect the appearance quality of the coil and the damage on the coil at the inspection site. The online coil thickness gauge is used to inspect the thickness of the coil to ensure that the thickness of the coil at the production site is uniform.

[0012] Furthermore, it also includes a label pasting and marking mechanism, which includes an L-shaped plate and a pulling motor, the rear side of the left end of the synchronous cross plate is fixedly connected to the support plate by screws, the top of the support plate is fixedly connected to the L-shaped plate, the top of the vertical part of the L-shaped plate is rotatably connected to the release shaft, the middle part of the vertical part of the L-shaped plate is rotatably connected to the pulling shaft, the rear end of the pulling shaft is fixedly connected to the pulling motor, and the bottom of the horizontal part of the L-shaped plate is provided with a separation inclined plate that is higher on the left and lower on the right, a label roll is fixedly sleeved on the release shaft, a release paper tape is wrapped around the label roll, labels are equidistantly adhered to the release paper tape, and the release paper tape bypasses the right end of the separation inclined plate and is wrapped around the pulling shaft.

Since the front bottom of the label may not be firmly pasted to the upper side of the rear edge of the coil, a label pressing roller is provided, and the label pressing roller is located on the upper side of the coil between the two longitudinal support shafts. When the coil moves from left to right, the friction between the coil and the label pressing roller causes the label pressing roller to rotate counterclockwise, and the label on the coil is pressed by the label pressing roller when passing the bottom of the label pressing roller, so that the front side of the label is pressed and pasted to the upper side of the rear edge of the coil more stably.

[0014] Furthermore, it also includes a label folding and pasting mechanism, which includes an electric telescopic rod and a label pressing plate, the synchronous cross plate is fixedly connected to a bracket at a position on the right side of the support plate, an arc trajectory control component is installed on the top of the bracket, a follower seat plate is installed on the front side of the arc trajectory control component, an electric telescopic rod is installed on the middle rear side of the follower seat plate, and the telescopic end of the front side of the electric telescopic rod passes through the middle through hole of the follower seat plate and is connected to the label pressing plate.

[0016] Compared with the prior art, the beneficial effects of the automatic reel detection and bad position marking device are:

[0017] 1. The lifting adjustment assembly is used to drive the lifting adjustment plate to move up and down. When the lifting adjustment plate descends, the friction arc plate and the friction disc are more tightly attached, and the coil sleeve on the left side will encounter greater resistance when rotating. When the lifting adjustment plate rises, the friction between the friction arc plate and the friction disc decreases, and the coil sleeve on the left side will encounter smaller resistance when rotating. The friction telescopic rod and the friction spring buffer the distance between the lifting adjustment plate and the friction arc plate. There is friction when the coil to be released rotates, which prevents the coil from being released too much due to inertia after the pulling of the coil stops.

[0018] 2. The coil to be inspected is heavier in the initial inspection stage, so it presses on the gravity follow-up component, shortening the gravity follow-up component, and the vertical support block moves down a short distance along the vertical groove. At this time, the adjustable coil friction release mechanism has less resistance to the rotation of the coil sleeve on the left, and the winding motor does not need a large power to pull the coil sleeve on the left, so that the coil to be inspected on the left coil sleeve is released. As the coil to be inspected is released, its gravity becomes smaller, the gravity follow-up component rebounds and stretches, and the vertical support block moves up a short distance along the vertical groove. During this process, the adjustable coil friction release mechanism increases its resistance to the rotation of the coil sleeve on the left, thereby preventing the coil from being easily pulled by the winding motor after the gravity of the coil to be inspected is reduced, causing excessive release of the coil.

[0019] 3. The label pasting and marking mechanism pastes the front side of the label to the upper side of the rear edge of the coil, and the label folding and pasting mechanism pastes the rear side of the label to the lower side of the rear edge of the coil. The labels are pasted on the upper and lower sides of the edge of the coil to mark the defective position. The defective position of the coil can be known without unfolding the coil, which is convenient for the subsequent rapid processing of the defective position. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] When the coiled material sleeved on the left coiled material sleeve 19 is heavier, the gravity follower spring 18 is compressed, the gravity follower vertical telescopic rod 17 is shortened, and the vertical support block 15 descends along the vertical groove 14. After the coiled material sleeved on the left coiled material sleeve 19 is released, its own weight is reduced, the gravity follower spring 18 is reset and extended, the gravity follower vertical telescopic rod 17 is extended, and the vertical support block 15 moves up along the vertical groove 14.

The front end of the tightening screw 31 is fixedly connected with a hand wheel 2 39, and the hand wheel 2 39 is located at the front end of the coil sleeve 19.

[0044] The core sleeve for winding the coil is installed on the outer peripheral side of the coil sleeve 19. At this time, the core sleeve will rotate relative to the uncontrolled coil sleeve 19. The tightening screw 31 is rotated clockwise by the hand wheel 2 39, and the threaded action of the tightening screw 31 and the tightening screw nut 38 drives the tightening screw nut 38 to move backward, and the tightening screw nut 38 drives the front end of the fork rod 2 34 to move backward. During this process, the cross column 37 moves backward along the longitudinal groove 36, and the scissor-fork connecting rod composed of the fork rod 1 33, the fork rod 2 34 and the central axis is used to push the tightening rod 310 out of the tightening limit groove. The three tightening rods 310 are synchronously extended from the three tightening limit grooves, which can tighten the inner side of the core sleeve and ensure that the core sleeve and the coil sleeve 19 are in a concentric state.

[0045] It also includes an adjustable coil friction release mechanism 2 and a coil flattening mechanism 5. The adjustable coil friction release mechanism 2 is installed on the top of the left support 13, the coil flattening mechanism 5 is installed between the right support 12 and the left support 13, and the coil flattening mechanism 5 is installed with a reel-reel rear end alignment mechanism 4, and a coil detection mechanism 6 is installed on the front side of the reel-reel rear end alignment mechanism 4.

[0047] The lifting adjustment assembly includes a horizontal support plate 21, a column 22, a vertical screw 23, a hand wheel 24, a lifting screw nut 210, and a top seat 211. The top of the left support 13 is fixedly connected to the top seat 211 by screws, and the rear side of the top seat 211 is fixedly connected to the horizontal support plate 21. Two columns 22 are vertically slidably connected in two sliding holes on the horizontal support plate 21. Both columns 22 are fixedly connected to the top of the lifting adjustment plate 25.

The top of the vertical screw 23 is fixedly connected with a hand wheel 24. The vertical screw 23 is rotated clockwise by the hand wheel 24. The threaded action of the vertical screw 23 and the lifting screw nut 210 allows the vertical screw 23 to move upward relative to the horizontal support plate 21 and the lifting screw nut 210. The vertical screw 23 drives the lifting adjustment plate 25 to move upward stably through the guiding action of the column 22. The vertical screw 23 is rotated counterclockwise by the hand wheel 24, which drives the lifting adjustment plate 25 to move downward.

[0048] The lifting adjustment assembly is used to drive the lifting adjustment plate 25 to move up and down. When the lifting adjustment plate 25 descends, the friction arc plate 28 and the friction disc 29 are more tightly attached, and the coil sleeve 19 on the left side will encounter greater resistance when rotating. When the lifting adjustment plate 25 rises, the friction force between the friction arc plate 28 and the friction disc 29 is reduced, and the coil sleeve 19 on the left side will encounter smaller resistance when rotating. The friction telescopic rod 26 and the friction spring 27 have a buffering effect on the distance between the lifting adjustment plate 25 and the friction arc plate 28, ensuring that the friction arc plate 28 and the friction disc 29 can generate relative friction, avoiding the friction arc plate 28 completely leaving the friction disc 29 when the lifting adjustment plate 25 is raised, and also avoiding the friction arc plate 28 and the friction disc 29 being completely squeezed and locked when the lifting adjustment plate 25 descends. Therefore, the friction telescopic rod 26 and the friction spring 27 are used to cooperate with the lifting adjustment assembly to adjust the friction force between the friction arc plate 28 and the friction disc 29.

The two longitudinal support shafts 53 have the same horizontal height. Therefore, the part of the coil located between the two longitudinal support shafts 53 remains in a horizontal state, which is convenient for detection by the coil detection mechanism 6.

The rear side of the synchronous cross plate 42 is fixedly connected to two longitudinal guide rods 41, and the two longitudinal guide rods 41 are respectively connected to the two guide holes on the cross beam 51 for longitudinal sliding. The rear side of the synchronous cross plate 42 is rotatably connected to the front end of the longitudinal screw 43 through a bearing. The cross beam 51 is inlaid with a longitudinal screw nut 44, which is fixedly connected to the longitudinal screw 43. The longitudinal screw nut 44 and the longitudinal screw 43 are threaded. The rear end of the longitudinal screw 43 is fixed. A hand wheel three 45 is fixedly connected, and the longitudinal guide rod 41 guides the synchronous cross plate 42, so that the synchronous cross plate 42 can only move forward and backward relative to the cross beam 51. The longitudinal screw 43 is rotated clockwise by the hand wheel three 45, and the threaded action of the longitudinal screw 43 and the longitudinal screw nut 44 allows the longitudinal screw 43 to move forward relative to the cross beam 51 and the longitudinal screw nut 44, thereby driving the synchronous cross plate 42 to move forward. The longitudinal screw 43 is rotated counterclockwise by the hand wheel three 45 to drive the synchronous cross plate 42 to move backward.

[0053] The coil edge limiting assembly includes a front limiting ring 54, a positioning sleeve 55, a positioning screw 56, a vertical rod 57, a rear support ring 58, and a rear limiting ring 59. The positions of the two longitudinal support shafts 53 corresponding to the top of the synchronous cross plate 42 are respectively fixedly connected to two vertical rods 57, and the tops of the two vertical rods 57 are respectively fixedly connected to two rear support rings 58. The rear ends of the two longitudinal support shafts 53 pass through the two rear support rings 58 respectively, and the front sides of the two rear support rings 58 are respectively rotatably connected to two rear limiting rings 59. The rear support rings 58 and the rear limiting rings 59 move with the synchronous cross plate 42 to pass through the upper sides of the two longitudinal support shafts 53. The rear edge of the coil is limited, and the rear limit ring 59 can rotate relative to the rear support ring 58, which can reduce the wear on the rear edge of the coil. The front end sliding sleeve of each longitudinal support shaft 53 is connected with a positioning sleeve 55, and the screw hole in the positioning sleeve 55 is threadedly connected with a positioning screw 56. The positioning screw 56 is pressed against the longitudinal support shaft 53. The positioning sleeve 55 can be fixed on the longitudinal support shaft 53 by means of the positioning screw 56. The positioning sleeve 55 can be moved forward and backward by loosening the positioning screw 56 to adapt to coils of different widths. A front limit ring 54 is arranged on the rear side of the positioning sleeve 55, and the front limit ring 54 limits the front edge of the coil.

[0054] The longitudinal movement control assembly is used to drive the synchronous cross plate 42 to move forward and backward. The two follower longitudinal telescopic rods 411 cooperate with the two follower brackets 410 to limit the follower plate 49 and the rear baffle ring 46 on the follower plate 49, so that the follower plate 49 and the rear baffle ring 46 can only move forward and backward relative to the vertical support block 15. When the vertical support block 15 moves up and down, the follower plate 49 and the rear baffle ring 46 will move up and down relative to the synchronous cross plate 42 through the cooperation of the vertical guide bar 48 and the guide groove, ensuring that the synchronous cross plate 42 can drive the two rear baffle rings 46 to move forward and backward when it moves forward and backward, and at the same time does not interfere with the vertical support block 15 as the coil sleeve 19 on the left side moves up and down. Because the two core sleeves are easily misaligned when they are respectively sleeved on the two coil sleeves 19, two rear retaining rings 46 are provided to limit the rear ends of the two core sleeves, so that the coil to be detected on the left core sleeve and the rear side of the coil wound and reeled on the right core sleeve can also be aligned. Since the rear retaining ring 46 cannot rotate with the core sleeve and the coil sleeve 19, the rear edge of the coil on the core sleeve will rub against the rear retaining ring 46, which will damage the coil. Therefore, two swivel rings 47 are provided, which are used to limit the core sleeve and the rear side of the coil on the core sleeve, and the swivel ring 47 will rotate with the core sleeve and will not wear the coil on the core sleeve.

[0055] The coil inspection mechanism 6 includes an inspection mounting seat 69, an online coil thickness gauge 610, a quality inspection camera 611 and a shift adjustment component. The inspection mounting seat 69 is installed on the front left end of the synchronous cross plate 42 through the shift adjustment component, and the quality inspection camera 611 and the online coil thickness gauge 610 are installed on the left and right sides of the inspection mounting seat 69 respectively.

[0056] The shift adjustment assembly includes a longitudinal support plate 61, a longitudinal guide rail 62, a longitudinal slide seat 63, a longitudinal fastening bolt 64, a vertical plate 65, a vertical guide rail 66, a vertical slide seat 67, and a vertical fastening bolt 68. The left front end of the synchronous cross plate 42 is fixedly connected with the longitudinal support plate 61, the longitudinal guide rail 62 is fixedly connected to the longitudinal support plate 61, the longitudinal guide rail 62 is longitudinally slidably connected with the longitudinal slide seat 63, and the side of the longitudinal slide seat 63 is threadedly connected with the longitudinal fastening bolt 64, the longitudinal fastening bolt 64 is pressed against the side of the longitudinal guide rail 62, and the longitudinal fastening bolt 64 is loosened to allow the longitudinal slide seat 63 to move forward along the longitudinal guide rail 62. The vertical slide seat 67 is connected to the vertical guide rail 66 in a vertical sliding manner, and the side of the vertical slide seat 67 is threadedly connected with a vertical fastening bolt 68. The vertical fastening bolt 68 presses against the vertical guide rail 66, and the front side of the vertical slide seat 67 is fixedly connected with the detection mount 69. After loosening the vertical fastening bolt 68, the vertical slide seat 67 can move up and down along the vertical guide rail 66, thereby changing the height of the detection mount 69.

[0057] The coil online thickness gauge 610 adopts existing technology, such as an ultrasonic thickness gauge.

[0058] The shift adjustment assembly is used to adjust the position of the detection mounting seat 69, thereby changing the position of the quality inspection camera 611 and the online coil thickness gauge 610. The quality inspection camera 611 is used to detect the appearance quality of the coil and detect damage on the coil. The online coil thickness gauge 610 is used to detect the thickness of the coil to ensure that the thickness of the coil at the production site is uniform.

[0059] When in use, the core sleeve of the coil 9 to be detected is sleeved on the left coil sleeve 19, and the core sleeve for winding and rewinding the coil 9 is sleeved on the right coil sleeve 19, and then the two core sleeves are tightened by the sleeve concentric tightening mechanism 3, so that the core sleeve and the coil sleeve 19 are kept in a concentric and fixed state, and the winding motor 110 drives the coil sleeve 19 on the right to rotate, and the core sleeve on the coil sleeve 19 rotates clockwise to start winding the coil 9, so as to pull the coil to the right, and the coil 9 to be detected and the coil sleeve 19 on the left rotate clockwise to release the coil 9, and the adjustable winding The material friction release mechanism 2 can adjust the friction force of the left coil sleeve 19 when it rotates. Since the left coil sleeve 19 is subjected to friction when it rotates, when the winding motor 110 stops working, the left coil sleeve 19 will not continue to rotate due to inertia, so as to avoid the left coil sleeve 19 releasing too much coil 9. The coil to be detected is heavier in the initial detection stage, so it presses the gravity follower component to shorten the gravity follower component, and the vertical support block 15 moves down a short distance along the vertical groove 14. At this time, the adjustable coil friction release mechanism 2 is for the left coil sleeve 1 9 has a small resistance when rotating, and the winding motor 110 does not need a large power to pull the coil sleeve 19 on the left side, so that the coil 9 to be detected on the left coil sleeve 19 is released. As the coil 9 to be detected is released, its gravity becomes smaller, and the gravity follower component rebounds and stretches, and the vertical support block 15 moves up a short distance along the vertical groove 14. In this process, the resistance of the adjustable coil friction release mechanism 2 to the rotation of the left coil sleeve 19 is increased, so as to avoid the coil 9 to be detected from being easily pulled by the winding motor 110 after the gravity of the coil is reduced, causing excessive release of the coil 9. The gravity follower component can adjust the resistance to the rotation of the coil sleeve 19 according to the gravity of the coil to be detected on the left coil sleeve 19, so as to realize the stable release of the coil 9 by the left coil sleeve 19. The coil flattening mechanism 5 is located between the tops of the two coil sleeves 19, and is used to flatten the coil, ensuring that the coil detection mechanism 6 can detect the flat coil 9 and improve the accuracy of the detection. The rear end alignment mechanism 4 of the retractable coil can align the rear ends of the core sleeves on the two coil sleeves 19, ensuring that the rear edge of the coil 9 is kept neat when the core sleeve is wrapped around the coil 9.

[0060] For example 2, please refer to Figures 1 to 10 ,This embodiment provides a technical solution: an automatic reel detection and bad position marking device, the structure of this embodiment is roughly the same as that of the first embodiment, the difference is that;

[0061] The label pasting and marking mechanism 7 also includes a support plate 71, an L-shaped plate 72, a release shaft 73, a pulling motor 74, an anti-sticking paper tape 75, a label 76, a pulling shaft 77 and a separation inclined plate 710. The left rear end of the synchronous cross plate 42 is fixedly connected to the support plate 71 by screws, the top of the support plate 71 is fixedly connected to the L-shaped plate 72, the top of the vertical part of the L-shaped plate 72 is rotatably connected to the release shaft 73, and the middle part of the vertical part of the L-shaped plate 72 is rotatably connected to the release shaft 73. It is dynamically connected to a pulling shaft 77, and the rear end of the pulling shaft 77 is fixedly connected to a pulling motor 74. The pulling motor 74 is installed on the rear side of the L-shaped plate 72. A separation inclined plate 710 with a left higher and right lower slant is provided at the bottom of the horizontal part of the L-shaped plate 72. A label roll is fixedly sleeved on the release shaft 73, and a release paper tape 75 is wound around the label roll. Labels 76 are adhered to the release paper tape 75 at equal distances. The release paper tape 75 passes around the right end of the separation inclined plate 710 and is wound around the pulling shaft 77.

[0062] In order to allow the release shaft 73 to release the anti-sticking paper tape 75 in an orderly manner, the rotation of the release shaft 73 needs to be subjected to a certain friction force. The existing technology can be used to allow the rotation of the release shaft 73 to be subjected to the friction force.

[0063] When the quality inspection camera 611 and the online thickness gauge 610 for the roll material detect that there is a bad position in the roll material, the pulling motor 74 starts to drive the pulling shaft 77 to rotate clockwise, and the pulling shaft 77 is wound around the anti-sticking paper tape 75. The anti-sticking paper tape 75 is released as the label roll on the release shaft 73 rotates clockwise, and the label 76 on the anti-sticking paper tape 75 approaches the right end of the separation inclined plate 710, and the right side of the label 76 is separated from the anti-sticking paper tape 75. As the anti-sticking paper tape 75 continues to bypass the right end of the separation inclined plate 710, the front bottom of the label 76 is attached to the upper side of the rear edge of the roll material. As the roll material moves from left to right, the front bottom of the label 76 is finally stably attached to the upper side of the rear edge of the roll material. Since the support plate 71 is installed on the synchronous cross plate 42, even if the synchronous cross plate 42 moves back and forth, the label 76 can always be aligned with the rear edge of the roll material.

[0064] The label pasting and marking mechanism 7 also includes a limiting roller 78 and a limiting guide ring 79. The front side of the L-shaped plate 72 is located at the left side of the separation inclined plate 710 and is rotatably connected to the rear end of the limiting roller 78. The upper and lower sides of the limiting roller 78 are in rolling contact with the anti-sticking paper tape 75, and the limiting roller 78 is located at the front and rear sides of the anti-sticking paper tape 75 and is fixedly sleeved with the limiting guide ring 79 respectively. The limiting guide ring 79 limits the front and rear sides of the anti-sticking paper tape 75.

[0065] The label pasting and marking mechanism 7 further includes a label pressing roller 711. The right end of the horizontal part of the L-shaped plate 72 is rotatably connected to the rear side of the label pressing roller 711. The label pressing roller 711 is located on the right side of the separation inclined plate 710. Since the front bottom of the label 76 may not be firmly pasted to the upper side of the rear edge of the coil, the label pressing roller 711 is provided. The label pressing roller 711 is located on the upper side of the coil between the two longitudinal support shafts 53. When the coil moves from left to right, the friction between the coil and the label pressing roller 711 causes the label pressing roller 711 to rotate counterclockwise. When the label 76 on the coil passes the bottom of the label pressing roller 711, it is pressed by the label pressing roller 711, so that the front side of the label 76 is pressed and pasted to the upper side of the rear edge of the coil more stably.

[0066] For example 3, please refer to Figures 1 to 10 ,This embodiment provides a technical solution: an automatic reel detection and bad position marking device, the structure of this embodiment is roughly the same as that of the second embodiment, the difference is that;

[0067] It also includes a label folding and pasting mechanism 8, which includes a bracket 81, an arc trajectory control component, a follower seat plate 89, an electric telescopic rod 810 and a label pressing plate 811. The synchronous cross plate 42 is located at the right side of the support plate 71 and is fixedly connected to the bracket 81. The top of the bracket 81 is installed with an arc trajectory control component, the front side of the arc trajectory control component is installed with a follower seat plate 89, the middle rear side of the follower seat plate 89 is installed with an electric telescopic rod 810, and the telescopic end of the front side of the electric telescopic rod 810 passes through the middle through hole of the follower seat plate 89 and is connected to the label pressing plate 811. The label pasting and marking mechanism 7 only sticks the front side of the label 76 on the coil, and the rear side of the label 76 is still in a suspended state. Therefore, a label folding and pasting mechanism 8 is provided. The arc trajectory control component is used to drive the center of the follower seat plate 89 to move along a trajectory of half an arc, and drive the label pressing plate 811 to gradually move from the upper side of the rear edge of the coil along the trajectory of half an arc to the lower side of the rear edge of the coil. The rear side of the label 76 can be folded downward and then pasted to the lower side of the rear edge of the coil, so as to achieve stable pasting of the label 76 on the upper and lower sides of the rear edge of the coil. The electric telescopic rod 810 can change the distance between the label pressing plate 811 and the label 76, and cooperate with the arc trajectory control component to better fold and paste the label 76.

[0068] The arc trajectory control component includes a longitudinal support seat 82, a rotating shaft 83, a follower triangle plate 84, a U-shaped rod 85, a convex seat 86, an active triangle plate 87, a power motor 88 and a power shaft 812. The top of the bracket 81 is fixedly connected to the longitudinal support seat 82, and the rear end of the longitudinal support seat 82 is rotatably connected to the power shaft 812. The left end of the power shaft 812 is fixedly connected to the power motor 88. The power motor 88 is installed on the left side of the rear end of the longitudinal support seat 82. The right end of the power shaft 812 is fixedly connected to the front end of the active triangle plate 87. The upper and lower ends of the movable triangle plate 87 are respectively movably connected to the rear ends of the two U-shaped rods 85 through two movable shafts 1, and the middle parts of the two U-shaped rods 85 on opposite sides are respectively fixedly connected to two convex seats 86. The front end of the longitudinal support seat 82 is rotatably connected to the transverse rotating shaft 83, and the rotating shaft 83 is fixedly connected to the front end of the follower triangle plate 84. The upper and lower ends of the follower triangle plate 84 are respectively movably connected to the two convex seats 86 through two movable shafts 2, and the front ends of the two U-shaped rods 85 are respectively movably connected to the upper and lower ends of the follower seat plate 89 through two movable shafts 3. Fig. 9 For example, the power motor 88 drives the power shaft 812 to rotate ninety degrees clockwise, and the power shaft 812 drives the active triangular plate 87 to rotate clockwise. The two movable shafts 1 and the two movable shafts 2 always form a parallelogram. Due to the cooperation of the rotating shaft 83, the follower triangular plate 84 and the convex seat 86, the height of the two U-shaped rods 85 is gradually reduced, and the upper U-shaped rod 85 moves right relative to the lower U-shaped rod 85, so that the follower seat plate 89 can be gradually rotated ninety degrees clockwise while the height is reduced, and the label pressing plate 811 can be rotated ninety degrees clockwise and wound to the bottom of the rear edge of the coil at the same time;

[0069] On the contrary, the power motor 88 drives the power shaft 812 to rotate counterclockwise by 90 degrees, so that the height of the two U-shaped rods 85 gradually increases, and the upper U-shaped rod 85 is sufficient relative to the lower U-shaped rod 85, so that the follower seat plate 89 can be gradually rotated counterclockwise by 90 degrees while the height increases, and the label pressing plate 811 can be rotated counterclockwise by 90 degrees and wound around the upper rear edge of the coil at the same time;

[0070] The power shaft 812 can be driven to rotate within an angle range of 180 degrees, so that the movable label pressing plate 811 can fold the rear side of the label downward and then stick it to the lower side of the rear edge of the coil.

[0071] It is worth noting that the winding motor 110, the online coil thickness gauge 610, the quality inspection camera 611, the pulling motor 74, the electric telescopic rod 810, and the power motor 88 disclosed in the above embodiments are all controlled by an external PLC controller, and the control method thereof adopts the method commonly used in the prior art. The winding motor 110, the pulling motor 74, and the power motor 88 all adopt servo motors.
