Description

Technical Field

[0001] This invention relates to the technical field of automatic steel coil feeding, and more particularly to an integrated control method for automatic steel coil feeding and centering in an uncoiler. Background Technology

[0002] Uncoiling machines are one of the core pieces of equipment in metal sheet processing production lines. As the first step in uncoiling, the efficiency and precision of steel coil feeding directly affect the overall quality of the production line.

[0003] Patent publication number CN209383102U discloses an automatic steel coil feeding device, with main classification number B65H. It includes a steel coil tray, an unwinding shaft, a control device, a steel coil center detection device, and a steel coil conveying track. The steel coil tray slides horizontally on the steel coil conveying track via a transmission motor. The unwinding shaft moves vertically on the main body of the automatic steel coil feeding device. The control device is electrically connected to the transmission device of the unwinding shaft, the steel coil center detection device, and the transmission motor. By receiving data from the steel coil center detection device, the control device controls the lifting and lowering of the unwinding shaft and the operation of the transmission motor, allowing the steel coil to be quickly placed onto the unwinding shaft from the steel coil tray without requiring worker adjustment, reducing labor intensity and eliminating safety hazards.

[0004] Currently, most steel coil loading methods use tools such as loading trolleys, cranes, or forklifts for handling and placement. Although this can achieve automatic loading of steel coils to a certain extent, the steel coil pallets only support the steel coils from the outside through the supporting concave surface. The steel coils lack active fixation and limiting on the pallets, and there is still a risk of swaying during the loading process. In addition, the supporting concave surface is a fixed structure and cannot be adaptively adjusted according to the inner diameter and thickness of different steel coils. Furthermore, this solution relies on a single central detection device for centering control and lacks real-time centering and correction capabilities during the loading process.

[0014] As a preferred embodiment of the automatic steel coil feeding device for the uncoiler described in this invention, a vision sensor is provided on the left side of the variable diameter adjustment center fixing plate, and the vision sensor is used in conjunction with the longitudinal adjustment plate and the horizontal adjustment plate.

[0015] In a preferred embodiment of the automatic steel coil feeding device for the uncoiler described in this invention, an external spring rod is fixedly connected to the back end of the bonding support plate, an external guard plate is fixedly connected to the back end of the external spring rod, a connecting plate is fixedly connected to the left side of the front end of the external guard plate, shaft plates are fixedly connected to the left and right sides of the connecting plate, a guard rod is movably connected to the top and bottom of the inner side of the shaft plate via a rotating shaft, the guard rod is connected via a transmission belt, and a left anti-fall plate is fixedly connected to the left side of the external guard plate.

[0017] In a preferred embodiment of the automatic steel coil feeding device for the uncoiler described in this invention, the upper shaft and the upper bonding control rod are connected by a transmission belt, and the lower shaft and the lower bonding control rod are connected by a transmission belt.

[0018] In view of the problems existing in the current uncoiler centering integrated control method, the present invention is proposed.

[0019] Therefore, the purpose of this invention is to provide an integrated control method for centering an uncoiler, the purpose of which is to provide adaptive variable diameter adaptation and automatic centering.

[0020] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including acquiring image data of the inner circle of the steel coil through a vision sensor, obtaining the inner circle diameter, thickness and center position information of the current steel coil, and transmitting the acquired data to the control system;

[0021] Based on the steel coil parameters fed back by the vision sensor, the control system controls the longitudinal adjustment plate to slide along the longitudinal slide plate to a height position that matches the thickness of the steel coil, and at the same time controls the horizontal adjustment plate to slide along the horizontal slide plate, driving the bonding support plate and bonding plate fixing parts to move towards the inner circle of the steel coil, so that the main bonding plate is bonded to the inner wall of the inner circle of the steel coil, the outer guard plate clamps inward, and the left anti-fall plate is placed on the left side of the steel coil.

[0022] The pusher cylinder drives the pusher plate to move to the left, which in turn drives the inner coil bonding mechanism to bond with the supported steel coil. During the pushing process, the centering sensor detects the centering deviation signal between the end face of the steel coil and the uncoiler mandrel and feeds it back to the control system. The control system controls the moving feeding base to make adjustments based on the deviation signal until the centering sensor feedback signal meets the centering accuracy requirements. The steel coil then reaches the center position of the uncoiler mandrel, completing the feeding and centering.

[0023] As a preferred embodiment of the uncoiler centering integrated control method of the present invention, the method includes: when the horizontal adjusting plate slides, it drives the adjusting toothed plate to move horizontally; the adjusting toothed plate drives the transmission gear to rotate; through the sequential meshing of the first sector gear, the second sector gear, the universal joint, the third sector gear, and the fourth sector gear, it drives the synchronizing rod and the synchronizing gear to rotate; the synchronizing gear drives the bonding control gear to rotate; and then through the lower bonding control rod, it pulls the steel wire rope, pulling the side bonding plate to change its angle, so that the side bonding plate is bonded to the inner wall of the steel coil, thus completing the full bonding support of the inner coil.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This invention, by setting up a steel coil inner ring bonding mechanism and a diameter adjustment component, allows the diameter adjustment component to adapt to different steel coil thicknesses by sliding along a longitudinal slide plate via a longitudinal adjustment plate, and simultaneously adapt to different steel coil inner ring diameters by sliding along a horizontal slide plate via a horizontal adjustment plate. This enables the main bonding plate to adjust its diameter according to the inner ring diameter and thickness of different steel coils and to bond with the inner wall of the steel coil inner ring, thereby achieving active bonding support for the inner rings of steel coils of different specifications. This not only solves the problem that existing feeding devices cannot adapt to steel coils of different specifications, but also effectively prevents the steel coils from shaking or falling during transportation and feeding due to the lack of inner ring constraint, greatly improving the safety and versatility of the feeding process.

[0026] 2. This invention, by setting up a variable diameter bonding component, enables the bonding control gear to rotate when the horizontal adjustment plate slides. This is achieved through the sequential meshing of the adjusting tooth plate, transmission gear, first sector gear, second sector gear, universal joint, third sector gear, fourth sector gear, synchronizing rod, and synchronizing gear. Consequently, the lower bonding control rod pulls the steel wire rope, causing the side bonding plate to flip outward and unfold, thus bonding the side bonding plate with the inner wall of the steel coil. This achieves full bonding support of the inner coil by the main bonding plate and the side bonding plate, effectively increasing the bonding area and support stability, and further ensuring the stability of the steel coil's posture during transportation and pushing.

[0027] 3. This invention, by setting up guard rods and a left-side anti-fall plate, allows the outer guard plate to clamp inwards via an external spring rod when the supporting plate moves towards the steel coil. The guard rod rotates under the drive of the transmission belt and abuts against both sides of the outer wall of the steel coil, forming an auxiliary clamping constraint on the outer circumference of the steel coil. The left-side anti-fall plate works in conjunction with it to prevent the steel coil from falling off from the left side. While the inner circle of the steel coil is fully supported by the main bonding plate and the side bonding plate, external protection is formed from the outside and end face of the steel coil, realizing dual protection and anti-fall protection for the steel coil. This effectively prevents the steel coil from slipping off the side due to accidental deviation during transportation and pushing, eliminating the safety hazard of the steel coil falling off, and further enhancing the stability of the steel coil during transportation.

[0028] 4. This invention incorporates a visual sensor and an alignment sensor. The visual sensor acquires image data of the inner coil of the steel coil to obtain information on the inner coil diameter, thickness, and center position, and feeds this information back to the control system, enabling feedforward parameter input for diameter adjustment. The alignment sensor detects the alignment deviation signal between the end face of the steel coil and the uncoiler mandrel in real time during the pushing process and feeds it back to the control system. The control system then adjusts the moving feeding base based on the deviation signal, forming a closed-loop alignment correction during the pushing process. This achieves fully automated control of the entire process from steel coil parameter sensing and adaptive diameter adjustment to pushing and alignment, improving alignment accuracy and eliminating safety hazards for operators in dangerous areas.

[0045] Example 1

[0046] The feeding mechanism 100 includes a movable feeding base 101, a steel coil placement platform fixed seat 102 fixedly connected to the top left side of the movable feeding base 101, a push control console 103 fixedly connected to the top right side of the steel coil placement platform fixed seat 102, a push cylinder 104 fixedly connected to the top of the push control console 103, a push plate 105 fixedly connected to the left side of the push cylinder 104, and the bottom of the push plate 105 and the top of the push control console 103 are slidably connected.

[0047] One embodiment of this example is as follows: The inner coil bonding mechanism 200 of the steel coil includes a diameter adjustment plate 201, which is fixed to the left side of the push plate 105. A diameter adjustment component 202 is provided on the left side of the diameter adjustment plate 201. A bonding support plate 203 is fixedly connected to the left side of the diameter adjustment component 202. An upper support rod 204 and a lower support rod 205 are fixedly connected to the top and bottom of the left side of the bonding support plate 203. A bonding plate fixing member 206 is fixedly connected to the left side of the upper support rod 204. The bottom right side of the bonding plate fixing member 206 is fixedly connected to the left side of the lower support rod 205. A bonding groove 207 is opened at the back end of the bonding plate fixing member 206. A main bonding plate 208 is fixedly connected to the inner wall of the bonding groove 207. A diameter bonding component 209 is provided at the front end of the bonding plate fixing member 206.

[0048] The variable diameter adjustment assembly 202 includes a longitudinal slide plate 202a. The right side of the longitudinal slide plate 202a and the left side of the variable diameter adjustment plate 201 are fixedly connected. Two longitudinal slide plates 202a are provided and distributed at the front and back ends of the left side of the variable diameter adjustment plate 201. A longitudinal adjustment plate 202b is slidably connected to the left side of the longitudinal slide plate 202a via an electric push rod. A horizontal slide plate 202c is fixedly connected to the front end of the longitudinal adjustment plate 202b. A variable diameter adjustment center fixing plate 202d is fixedly connected to the inner side of the horizontal slide plate 202c. A variable diameter adjustment center fixing plate 202d is slidably connected to the left side of the horizontal slide plate 202c via an electric push rod. A horizontal adjusting plate 202e is fixedly connected to the left side of the horizontal adjusting plate 202e and the right side of the fitting support plate 203. A toothed slide plate 202f is fixedly connected to the front end and back end of the left side of the variable diameter adjusting plate 201 and the bottom of the horizontal slide plate 202c. An adjusting toothed plate 202g is slidably connected to the top of the toothed slide plate 202f. A gear fixing part 202h is fixedly connected to the top of the toothed slide plate 202f. A transmission gear 202i is movably connected to the left side of the gear fixing part 202h through a rotating shaft. The bottom of the transmission gear 202i and the top of the adjusting toothed plate 202g are meshed.

[0049] A first sector gear 202j is fixedly connected to the left side of the transmission gear 202i. A movable sleeve 202k is fixedly connected to the top of the toothed slide groove 202f. A second sector gear 202l is movably connected to the inner cavity of the movable sleeve 202k via a rotating shaft. The right side of the second sector gear 202l meshes with the back end of the first sector gear 202j. A universal joint 202m is fixedly connected to the back end of the second sector gear 202l. A third sector gear 202n is fixedly connected to the back end of the universal joint 202m. A first sector gear fixing plate 202o is movably sleeved on the surface of the third sector gear 202n. The right side of the first sector gear fixing plate 202o is fixedly connected to... There is a second sector gear fixing plate 202p, the back end of the second sector gear fixing plate 202p is fixedly connected to the front end of the fitting support plate 203, a telescopic plate 202q is fixedly connected to the right side of the second sector gear fixing plate 202p, the bottom of the telescopic plate 202q is fixedly connected to the top of the adjusting tooth plate 202g, a fourth sector gear 202r is fixedly connected to the left side of the second sector gear fixing plate 202p, the front end of the fourth sector gear 202r is meshed with the right side of the third sector gear 202n, a synchronizing rod 202s is fixedly connected to the left side of the fourth sector gear 202r, and a synchronizing gear 202t is fixedly connected to the left side of the surface of the synchronizing rod 202s.

[0050] The universal joint 202m is equipped with a telescopic rod 202m-1, which is coordinated with the universal joint 202m to extend and rotate.

[0051] By setting up a telescopic rod 202m-1, which, in conjunction with the universal joint 202m, extends and rotates, when the horizontal adjusting plate 202e slides and drives the contact support plate 203 and the contact plate fixing part 206 to move, the telescopic rod 202m-1 inside the universal joint 202m can automatically extend and retract to compensate for the change in the distance between the second sector gear 202l and the third sector gear 202n. This ensures that the second sector gear 202l and the third sector gear 202n maintain stable transmission meshing during the diameter adjustment process, avoiding jamming or transmission failure caused by changes in the transmission path length due to horizontal adjustment displacement. This ensures that the gear transmission can reliably transmit power at any diameter change position, further improving the stability and reliability of the device operation.

[0052] When the horizontal adjusting plate 202e slides along the horizontal slide rail 202c, the horizontal adjusting plate 202e drives the telescopic plate 202q to move synchronously through the contact support plate 203 and the second sector gear fixing plate 202p. The telescopic plate 202q drives the adjusting toothed plate 202g to slide along the toothed plate slide rail 202f. When the adjusting toothed plate 202g slides, it drives the transmission gear 202i to rotate around its axis. The first sector gear 202j rotates synchronously with the transmission gear 202i. The second sector gear 202l is movably connected to the movable sleeve 202k through the rotating shaft. The tooth surface of the second sector gear 202l meshes with the tooth surface of the first sector gear 202j. The diameter of the first sector gear 202j is smaller than the diameter of the second sector gear 202l, forming the first stage of reduction transmission. The second sector gear 202... The gear 2021 is connected to the third sector gear 202n via a universal joint 202m. The telescopic rod 202m-1 inside the universal joint 202m is a spline telescopic rod. The two ends of the telescopic rod 202m-1 are fixedly connected to the back end shaft of the second sector gear 202l and the front end shaft of the third sector gear 202n, respectively. The axial length of the telescopic rod 202m-1 can adaptively expand and contract with the change of the distance between the second sector gear 202l and the third sector gear 202n. At the same time, the universal joint 202m allows for angular deviation between the second sector gear 202l and the third sector gear 202n during transmission, so as to ensure that the power transmission between the second sector gear 202l and the third sector gear 202n will not be interrupted due to the change of the spatial position of each component during the diameter adjustment process.

[0053] The tooth surface of the third sector gear 202n meshes with the tooth surface of the fourth sector gear 202r. The fourth sector gear 202r is fixedly connected to the right end of the synchronizing rod 202s. The synchronizing rod 202s rotates synchronously with the rotation of the fourth sector gear 202r. The synchronizing gear 202t is fixedly connected to the left side of the surface of the synchronizing rod 202s.

[0054] By setting up a steel coil inner ring bonding mechanism 200, a diameter adjustment component 202, a vision sensor 202d-1, and a centering sensor 102a, adaptive diameter adjustment and full bonding support for the inner ring diameter and thickness of steel coils of different specifications can be achieved. The steel coil is stably pushed to the center position of the uncoil mandrel to complete the centering and feeding. This solves the technical problems in the existing technology that the steel coil feeding process relies on manual operation, resulting in low centering accuracy, poor feeding efficiency, easy shaking and falling of the steel coil during transportation, and easy damage to the inner ring of the steel coil.

[0055] Example 2

[0056] Based on Embodiment 1, this embodiment takes into account the differences in the inner curvature of steel coils with different inner diameters. Relying solely on the single-point or single-sided support of the main bonding plate 208 is insufficient to effectively fix the inner ring of the steel coil, leading to a risk of swaying during pushing and transporting. Furthermore, insufficient bonding area can easily cause localized stress concentration and damage to the inner ring of the steel coil. Therefore, this embodiment provides a variable diameter bonding component 209, which includes an upper shaft 209a and a lower shaft 209b. Both the upper shaft 209a and the lower shaft 209b are equipped with… The upper shaft 209a and lower shaft 209b are both movably connected to the bonding plate fixing member 206 via a rotating shaft, located at the front end of the bonding plate fixing member 206. An upper shaft gear 209c is fixedly connected to the surface of the upper shaft 209a, and a lower shaft gear 209d is fixedly connected to the surface of the lower shaft 209b at a position corresponding to the upper shaft gear 209c. The bottom of the upper shaft gear 209c and the top of the lower shaft gear 209d are meshed together. An upper bonding control rod sleeve 209e is fixedly connected to both the top and bottom of the front end of the bonding plate fixing member 206. The lower fitting control rod sleeve 209f and the upper fitting control rod sleeve 209e are located at the top of the upper shaft 209a, and the lower fitting control rod sleeve 209f is located at the bottom of the lower shaft 209b. The inner cavity of the upper fitting control rod sleeve 209e is movably connected to the upper fitting control rod 209g via a rotating shaft, and the inner cavity of the lower fitting control rod sleeve 209f is movably connected to the lower fitting control rod 209h via a rotating shaft. The top and bottom of the front end of the fitting plate fixing component 206 are fixedly connected to the wire rope sleeve 209i, and the inner cavity of the wire rope sleeve 209i is provided with a wire rope. 209j, the top of the wire rope 209j passes through the wire rope sleeve 209i and the top of the lower bonding control rod 209h and is fixedly connected. The end of the wire rope 209j away from the lower bonding control rod 209h is fixedly connected to the side bonding plate 209k. The top of the side bonding plate 209k is movably connected to the bottom of the main bonding plate 208 through a rotating shaft and a spring. The right side of the surface of the lower bonding control rod 209h is fixedly connected to the bonding control gear 209l. The front end of the bonding control gear 209l is meshed with the back end of the synchronous gear 202t.

[0057] The diameter of the first sector gear 202j is smaller than the diameter of the second sector gear 202l, and the diameter of the synchronizing gear 202t is smaller than the diameter of the engagement control gear 209l.

[0058] The upper shaft 209a and the upper bonding control rod 209g are connected by a transmission belt, and the lower shaft 209b and the lower bonding control rod 209h are connected by a transmission belt.

[0059] The bonding plate fastener 206 has a frame structure. A mounting cavity is provided at the front end of the bonding plate fastener 206. The upper shaft 209a and lower shaft 209b are both located inside the mounting cavity at the front end of the bonding plate fastener 206 and are connected to the bonding plate fastener 206 via a rotating shaft. An upper shaft gear 209c is fixedly sleeved on the surface of the upper shaft 209a, and a lower shaft gear 209d is fixedly sleeved on the surface of the lower shaft 209b. The upper shaft gear 209c and lower shaft gear 209d mesh. The upper bonding control rod sleeve 209e is fixedly connected to the top of the front end of the bonding plate fastener 206 and is movably connected within it via a rotating shaft. An upper bonding control rod 209g is attached, which is connected to the upper shaft 209a via a transmission belt. A lower bonding control rod sleeve 209f is fixedly connected to the bottom front end of the bonding plate fixing component 206. A lower bonding control rod 209h is movably connected inside the sleeve via a rotating shaft. The lower bonding control rod 209h is connected to the lower shaft 209b via a transmission belt. When the upper shaft 209a and the lower shaft 209b rotate synchronously in opposite directions, the upper bonding control rod 209g and the lower bonding control rod 209h rotate synchronously, pulling the steel wire rope 209j to pull the side bonding plate 209k to rotate around it and the main bonding plate 208.

[0060] The front end of the contact control gear 209l meshes with the back end of the synchronous gear 202t. The diameter of the synchronous gear 202t is smaller than the diameter of the contact control gear 209l, forming a second-stage reduction transmission. The rotational power of the synchronous gear 202t is transmitted to the contact control gear 209l through meshing to drive the lower contact control rod 209h and the upper contact control rod 209g to rotate.

[0061] By setting up the variable diameter bonding component 209, the linkage control function of synchronously driving the side bonding plate 209k to flip and unfold outward during the horizontal sliding of the horizontal adjustment plate 202e is realized. At the same time as the variable diameter adjustment, the bonding of the main bonding plate 208 with the inner wall of the inner ring of the steel coil and the bonding of the side bonding plate 209k with the side wall of the inner ring of the steel coil are completed simultaneously. The main bonding plate 208 and the side bonding plate 209k together form an annular support surface that matches the curvature of the inner ring of the steel coil, realizing the all-round wrapping bonding support function of the inner ring of the steel coil. This effectively increases the bonding area and avoids damage caused by local stress concentration in the inner ring of the steel coil due to insufficient bonding area. At the same time, by actively constraining the inner ring of the steel coil, the degree of freedom of the steel coil in the radial and axial directions is restricted, so that the steel coil maintains a stable posture and is not easy to shake during the entire pushing and transportation process.

[0062] Example 3

[0063] Based on Embodiment 1, this embodiment considers that Embodiment 2 can achieve full bonding support for the inner ring of the steel coil by the main bonding plate 208 and the side bonding plate 209k. However, there is still a lack of auxiliary restraint on the outer wall of the steel coil. During transportation, if there is an accidental shaking or equipment failure, the steel coil may shift from the left side or even fall. Therefore, this embodiment sets up a guard rod 203e and a left anti-fall plate 203f. An external spring rod 203a is fixedly connected to the back end of the bonding support plate 203. An external guard plate 203b is fixedly connected to the back end of the external spring rod 203a. A connecting plate 203c is fixedly connected to the left side of the front end of the external guard plate 203b. A shaft plate 203d is fixedly connected to both the left and right sides of the connecting plate 203c. The top and bottom of the inner side of the shaft plate 203d are movably connected to the guard rod 203e through a rotating shaft. The guard rod 203e is connected through a transmission belt. The left anti-fall plate 203f is fixedly connected to the left side of the external guard plate 203b.

[0064] When the bonding support plate 203 moves toward the inner circle of the steel coil, the bonding support plate 203 pushes the outer guard plate 203b to move synchronously toward the steel coil via the outer spring rod 203a. The outer guard plate 203b drives the connecting plate 203c and the shaft plate 203d to move synchronously toward the steel coil. The shaft plate 203d drives the guard rod 203e to move synchronously toward the steel coil, so that the outer circumferential surface of the guard rod 203e abuts against the surface of the outer wall of the steel coil. The contact between the guard rod 203e and the outer wall of the steel coil forms an auxiliary clamping constraint on the outer circumference of the steel coil. At the same time, the outer guard plate 203b drives the left anti-fall plate 203f to move synchronously toward the steel coil. When the main bonding plate 208 is bonded in place by the electric push rod, the left end face of the left anti-fall plate 203f moves synchronously and bonds to the left end face of the steel coil, forming a blocking limit.

[0065] In practical applications, the movement position of the adjusting toothed plate 202g is particularly important. The adjusting toothed plate 202g is fixed to the bonding support plate 203 and the horizontal adjusting plate 202e through the telescopic plate 202q, the second sector gear fixing plate 202p, and the electric actuator. When the electric actuator receives the control command and starts, the transmission component starts to run. The adjusting toothed plate 202g slides on the top of the toothed plate slide 202f. It can not only change the bonding angle of the side bonding plate 209k through the transmission component and increase the bonding area, but also adjust and change the bonding position of the main bonding plate 208 so that the horizontal height and longitudinal height of the main bonding plate 208 are completely consistent with the inner diameter of the steel coil. It is also connected to the outer guard plate 203b and can cooperate with the guard rod 203e and the left anti-fall plate 203f to adjust and protect the outer diameter of the steel coil.

[0066] By setting up guardrail 203e and left-side anti-fall plate 203f, the inner circle of the steel coil is fully supported by the main bonding plate 208 and the side bonding plate 209k. At the same time, the guardrail 203e forms an auxiliary clamping constraint on the outer circumference of the steel coil from both sides of the outer wall, and the left-side anti-fall plate 203f forms a blocking limit from the left end face of the steel coil. This achieves multi-directional three-dimensional protection for the inner circle, outer wall and end face of the steel coil, effectively preventing the steel coil from shifting or slipping and falling from the side due to accidental shaking or equipment failure during transportation and pushing, and further enhancing the stability and safety of the steel coil throughout the transportation process.

[0067] Example 4

[0068] Based on Embodiment 1, this embodiment considers that the inner coil bonding mechanism 200 and the variable diameter adjustment component 202 in Embodiment 1 can achieve variable diameter adjustment according to the inner diameter and thickness of different steel coils and bond and support the inner coil of the steel coil. However, there are still problems such as the need for manual measurement, low efficiency and large error. At the same time, it is difficult to ensure the precise alignment of the steel coil and the mandrel of the uncoiler during the process of pushing the steel coil to the uncoiler. Therefore, this embodiment sets a vision sensor 202d-1 and an alignment sensor 102a. The vision sensor 202d-1 is set on the left side of the variable diameter adjustment center fixing plate 202d. The vision sensor 202d-1 is used in conjunction with the longitudinal adjustment plate 202b and the horizontal adjustment plate 202e. The alignment sensor 102a is set on the top of the front end of the steel coil placement table fixing seat 102. The alignment sensor 102a is used in conjunction with the moving feeding base 101 and the pushing cylinder 104.

[0069] The lens of the vision sensor 202d-1 is set towards the steel coil placement table fixing base 102. When the steel coil is placed on top of the steel coil placement table fixing base 102, the vision sensor 202d-1 faces the steel coil, collects the image data of the steel coil, and transmits the collected image data to the control system to calculate the inner diameter and thickness of the steel coil. The detection ends of the centering sensor 102a are all facing the surface of the steel coil and are used to detect the distance between the left and right sides of the steel coil surface and the center point of the uncoiler mandrel. The control system controls the moving feeding base 101 to adjust according to the deviation signal until the feedback signal of the centering sensor 102a meets the centering accuracy requirements, the steel coil reaches the center position of the uncoiler mandrel, and the feeding centering is completed.

[0070] During the actual operation, the hoisting equipment lifts the steel coil to be loaded onto the steel coil placement platform fixed seat 102 on the top of the mobile loading base 101. The steel coil is placed in a horizontal position on the surface of the steel coil placement platform fixed seat 102. After the control system is started, it first controls the vision sensor 202d-1 to perform an image acquisition on the inner end face of the steel coil. The vision sensor 202d-1 transmits the acquired image of the steel coil to the control system. Based on the inner diameter, thickness and center position of the steel coil, the electric push rod is controlled to extend or retract, so that the center height of the inner circle of the steel coil is consistent with the center height of the main bonding plate 208, and the main bonding plate 208 is brought close to the inner wall of the inner circle of the steel coil.

[0071] By setting up a vision sensor 202d-1 and an alignment sensor 102a, continuous monitoring and dynamic correction of the position of the steel coil during the pushing process are achieved, ensuring that the steel coil remains stable throughout the entire pushing stroke and is aligned with the mandrel of the uncoiler. This solves the problem in the prior art where the position of the steel coil shifts during the pushing process, requiring repeated manual intervention and adjustment. At the same time, it avoids the safety hazards that would arise from operators having to stand between the steel coil and the uncoiler for adjustment.

[0072] Working principle: At the start of the variable diameter adjustment, the horizontal adjusting plate 202e is controlled by the electric actuator to slide along the horizontal slide plate 202c. The horizontal adjusting plate 202e is fixedly connected to the support plate 203 and the second sector gear fixing plate 202p, which drives the telescopic plate 202q to move synchronously. The telescopic plate 202q then drives the adjusting tooth plate 202g, which is fixedly connected to it, to slide along the tooth plate slide groove 202f. During the sliding process of the adjusting tooth plate 202g, the adjusting tooth plate 202g drives the transmission gear 202i to rotate around its axis. The transmission gear 202i is coaxially fixedly connected to the first sector gear 202j. When the transmission gear 202i rotates, it drives the first sector gear 202j to rotate synchronously. The tooth arc of the first sector gear 202j meshes with the tooth arc of the second sector gear 202l. When the first sector gear 202j rotates, it drives the second sector gear 202l to rotate around the axis inside the movable sleeve 202k through meshing.

[0073] The second sector gear 202l is connected to the third sector gear 202n via a universal joint 202m. The rotational power of the second sector gear 202l is transmitted to the third sector gear 202n via the universal joint 202m. During the power transmission process, the telescopic rod 202m-1 inside the universal joint 202m adaptively extends and retracts with the change in the distance between the second sector gear 202l and the third sector gear 202n to compensate for the change in the length of the transmission path. At the same time, the universal joint 202m adapts to the angular deviation between the two to ensure that the power transmission is not interrupted.

[0074] The tooth arc of the third sector gear 202n meshes with the tooth arc of the fourth sector gear 202r. When the third sector gear 202n rotates, it drives the fourth sector gear 202r to rotate through meshing. The fourth sector gear 202r is fixedly connected to the right end of the synchronizing rod 202s. When the fourth sector gear 202r rotates, it drives the synchronizing rod 202s to rotate synchronously. The left side of the surface of the synchronizing rod 202s is fixedly connected to the synchronizing gear 202t. When the synchronizing rod 202s rotates, it drives the synchronizing gear 202t to rotate synchronously.

[0075] The back end of the synchronous gear 202t meshes with the front end of the bonding control gear 209l. When the synchronous gear 202t rotates, it drives the bonding control gear 209l to rotate through meshing. The diameter of the synchronous gear 202t is smaller than the diameter of the bonding control gear 209l, forming a speed reduction transmission. The bonding control gear 209l is fixedly connected to the surface of the lower bonding control rod 209h. When the bonding control gear 209l rotates, it drives the lower bonding control rod 209h to rotate around its axis.

[0076] The lower bonding control rod 209h is connected to the lower shaft 209b via a transmission belt. When the lower bonding control rod 209h rotates, it drives the lower shaft 209b to rotate synchronously via the transmission belt. The lower shaft 209b is fixedly connected to the lower shaft gear 209d. The lower shaft gear 209d meshes with the upper shaft gear 209c. When the lower shaft gear 209d rotates, it drives the upper shaft gear 209c to rotate in the opposite direction through meshing. The upper shaft gear 209c is fixedly connected to the upper shaft 209a, driving the upper shaft 209a and the lower shaft 209b to rotate synchronously in the opposite direction. The upper shaft 209a is connected to the upper bonding control rod 209g via a transmission belt. When the upper shaft 209a rotates, it drives the upper bonding control rod 209g to rotate synchronously via the transmission belt. At the same time, the lower bonding control rod 209h drives the upper bonding control rod 209g and the lower bonding control rod 209h to rotate synchronously in the opposite direction through the above transmission path.

[0077] When the lower bonding control rod 209h rotates, it winds the steel wire rope 209j fixedly connected to its end. The steel wire rope 209j slides along the inner cavity of the steel wire rope sleeve 209i and pulls the side bonding plate 209k to rotate around it and the main bonding plate 208. At the same time, the upper bonding control rod 209g pulls the upper side bonding plate 209k to rotate synchronously through the same steel wire rope 209j and steel wire rope sleeve 209i structure, so that the side bonding plates 209k on both the upper and lower sides are bonded to the upper and lower side walls of the inner ring of the steel coil, thus completing the full bonding support of the inner ring of the steel coil.

[0078] During diameter adjustment, the fitting support plate 203 moves to the left, and through the transmission of the external spring rod 203a, external guard plate 203b, connecting plate 203c and shaft plate 203d, the guard rod 203e and the left anti-fall plate 203f move synchronously to the position abutting against the outer wall and end face of the steel coil. At the same time, the inner ring of the main fitting plate 208 and the side fitting plate 209k fits and supports, completing the multi-directional protection of the steel coil. During transportation, the guard rod 203e moves with the outer wall of the steel coil in a rolling contact manner, and the left anti-fall plate 203f provides blocking and limiting from the end face. The external spring rod 203a can adapt to steel coils of different sizes and thicknesses for limiting. When an impact occurs, it compresses to absorb energy and elastically resets after the impact, forming a protective fit, thereby achieving multi-directional protection of the steel coil.

The telescopic rod (202m-1) cooperates with the universal joint (202m) to extend and rotate.

8. The automatic steel coil feeding device for an uncoiler according to claim 4, characterized in that: The upper shaft (209a) and the upper bonding control rod (209g) are connected by a transmission belt, and the lower shaft (209b) and the lower bonding control rod (209h) are connected by a transmission belt.

9. An integrated control method for centering an uncoiler, characterized in that: The automatic steel coil feeding device for an uncoiler, as described in any one of claims 1 to 8, further includes: The inner circle image data of the steel coil is collected by a vision sensor (202d-1) to obtain the current inner circle diameter, thickness and center position information of the steel coil, and the collected data is transmitted to the control system. The control system controls the longitudinal adjustment plate (202b) to slide along the longitudinal slide plate (202a) to a height position matching the thickness of the steel coil, based on the steel coil parameters fed back by the vision sensor (202d-1). At the same time, it controls the horizontal adjustment plate (202e) to slide along the horizontal slide plate (202c), driving the bonding support plate (203) and bonding plate fixing piece (206) to move towards the inner circle of the steel coil, so that the main bonding plate (208) is bonded to the inner wall of the inner circle of the steel coil, the outer guard plate (203b) clamps inward, and the left anti-fall plate (203f) is placed on the left side of the steel coil. The push cylinder (104) drives the push plate (105) to move to the left, which in turn drives the inner ring bonding mechanism (200) to bond with the supported steel coil. During the pushing process, the centering sensor (102a) detects the centering deviation signal between the end face of the steel coil and the uncoiler mandrel and feeds it back to the control system. The control system controls the moving feeding base (101) to make adjustments according to the deviation signal until the feedback signal from the centering sensor (102a) meets the centering accuracy requirements. The steel coil reaches the center position of the uncoiler mandrel, and the feeding centering is completed.

10. The uncoiler centering integrated control method according to claim 9, characterized in that: include, When the horizontal adjusting plate (202e) slides, it drives the adjusting toothed plate (202g) to translate. The adjusting toothed plate (202g) drives the transmission gear (202i) to rotate. Through the sequential meshing of the first sector gear (202j), the second sector gear (202l), the universal joint (202m), the third sector gear (202n), and the fourth sector gear (202r), the synchronous rod (202s) and the synchronous gear (202t) are driven to rotate. The synchronous gear (202t) drives the bonding control gear (209l) to rotate. Then, through the lower bonding control rod (209h), the steel wire rope (209j) is pulled, which pulls the side bonding plate (209k) to change the angle, so that the side bonding plate (209k) is bonded to the inner wall of the steel coil, thus completing the full bonding support of the inner coil of the steel coil.
