Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel coil processing equipment, specifically a coiling device for rolling stainless steel coils. Background Technology

[0002] Stainless steel coils are a key basic material in fields such as new energy, medical devices, high-end kitchenware, and building decoration. In the production process, rolling is the core process for achieving precise control of coil thickness. As the key equipment at the end of the rolling process, the coiling equipment needs to neatly coil the continuously rolled stainless steel strip into coils. The quality of the coiling directly determines the edge flatness, appearance integrity, and material utilization rate of the finished coil, as well as the subsequent deep processing stages such as leveling and cutting. It has a significant impact on the economic benefits and product competitiveness of the entire production line.

[0003] Currently, most common stainless steel coil rolling equipment on the market suffers from a core design flaw: the lack of an automatic alignment structure. This deficiency directly leads to multiple technical challenges during the coiling process, making it difficult to adapt to the needs of modern industrial production. On the one hand, due to the lack of automatic alignment capabilities, existing coiling equipment relies on manual adjustment of the strip position to achieve centering. Manual adjustment is not only inefficient, but also cannot accurately cope with instantaneous deviations during strip transmission (such as slight tension fluctuations in the rolling process or positional deviations caused by uneven strip thickness). The centering accuracy is extremely poor, and manual operation can only roughly control the approximate position of the strip, failing to achieve precise edge alignment. This often results in appearance defects such as "tower-shaped coils" (uneven edges) and "misaligned coils" after coiling, causing significant waste of stainless steel materials, extending the overall production cycle, and greatly increasing processing costs.

The first threaded rod passes through the slider and is threadedly connected to the slider. A control module is provided on the first motor. The control module is connected to the laser rangefinder sensor via an electrical signal. The cross-section of the sliding groove is inverted T-shaped.

[0008] To facilitate assembly of the winding shaft, the present invention includes the following improvements: a rectangular cavity is provided inside the positioning cylinder, and multiple slots are symmetrically arranged on the periphery of the positioning cylinder. A limiting block is slidably arranged in the slot, with an arc-shaped groove at the top and a second inclined surface at the bottom.

[0009] (III) Beneficial Effects Compared with the prior art, this utility model provides a winding device for rolling stainless steel coils, which has the following advantages: The strip offset is detected in real time by a laser rangefinder.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figures 1-4This utility model provides a winding device for rolling stainless steel coils, including a base plate 1. A base 5 is slidably mounted on the upper end of the base plate 1. A first driving component for driving the base 5 to move is provided on the base plate 1. A support plate 6 is vertically mounted on one end of the base 5. A positioning cylinder 12 is provided on the top of the support plate 6. The front end of the positioning cylinder 12 passes through the support plate 6 and is rotatably connected to the support plate 6. A second driving component for driving the positioning cylinder 12 to rotate is provided on the outer side of the support plate 6. Two support frames 2 are symmetrically arranged on the upper end of the base plate 1. Two guide rollers 3 are symmetrically arranged vertically between the two support frames 2. The two ends of the guide rollers 3 are rotatably connected to the support frames 2. A laser range sensor 4 is fixedly mounted on one side of one of the support frames 2. A detection probe located between the two guide rollers 3 is provided at the output end of the laser range sensor 4. The laser range sensor 4 is connected to the first driving component via an electrical signal.

[0014] Step 1: Assembly and fixing of the winding drum: The positioning cylinder 12 has a rectangular cavity 18 inside. Multiple slots 19 are symmetrically arranged around the periphery of the positioning cylinder 12. A limiting block 20 is slidably arranged in the slot 19. The top of the limiting block 20 has an arc-shaped groove, and the bottom of the limiting block 20 has a second inclined surface 21. Two driving blocks 22 are symmetrically arranged in the rectangular cavity 18. One side of the driving block 22 has a first inclined surface 23 that fits against the second inclined surface 21. A second motor 14 is fixedly arranged at the front end of the positioning cylinder 12. The output end of the second motor 14 has a second rotating shaft 24 that is inserted into the rectangular cavity 18. Two second threaded rods 13 with reverse thread structure are symmetrically arranged on the second rotating shaft 24. The two second threaded rods 13 pass through the front and rear driving blocks 22 respectively and are threadedly connected to the driving blocks 22. The outer wall of the driving block 22 is tightly fitted with the inner wall of the rectangular cavity 18, and the outer wall of the limiting block 20 is tightly fitted with the inner wall of the slot 19.

[0015] First, the take-up drum to be used is placed on the outside of the positioning drum 12, and then the second motor 14 fixed to the front end of the positioning drum 12 is started.

[0016] When the second motor 14 is running, the second shaft 24 at its output end will rotate synchronously. Since the second shaft 24 is provided with two second threaded rods 13 with reverse thread structure, and these two second threaded rods 13 respectively pass through and are threadedly connected to two driving blocks 22 in the rectangular cavity 18 inside the positioning cylinder 12 (the outer wall of the driving block 22 is tightly fitted with the inner wall of the rectangular cavity 18 to prevent the driving block 22 from shifting), the rotation of the second threaded rods 13 will drive the two driving blocks 22 to slide closer together in opposite directions in the rectangular cavity 18.

[0017] The drive block 22 has a first inclined surface 23 on one side, and the bottom of the limiting block 20 has a second inclined surface 21 that is completely in contact with the first inclined surface 23. The limiting block 20 is slidably embedded in the empty groove 19 on the periphery of the positioning cylinder 12 (the outer wall of the limiting block 20 is tightly in contact with the inner wall of the empty groove 19 to ensure smooth sliding).

[0018] When the drive block 22 approaches, the first inclined surface 23 will exert a uniform squeezing force on the second inclined surface 21, thereby pushing the limiting block 20 to move outward along the empty groove 19 until the arc-shaped groove at the top of the limiting block 20 completely fits the inner wall of the winding drum, thus achieving a firm assembly of the winding drum on the positioning cylinder 12 without the need for additional clamping tools.

[0019] Step 2: Insertion and fixing of stainless steel coils: The stainless steel coil to be wound is passed through the two support frames 2 symmetrically arranged at the upper end of the base plate 1. Two guide rollers 3 are symmetrically installed between the two support frames 2. The two ends of the guide rollers 3 are rotatably connected to the support frames 2. The strip can pass smoothly along the roller surface of the guide rollers 3. The guide rollers 3 can play a role in bidirectional guidance and stable transmission of the strip, reducing the shaking of the strip during transmission.

[0020] After the strip has completely passed through the gap between the two guide rollers 3, one end of the strip is tightly fixed to the outside of the assembled winding drum to prepare for the subsequent winding operation.

[0021] Step 3: Stainless steel coil winding operation: The second drive assembly includes a third motor 16, which is fixed to the outside of the support plate 6. A gear ring 15 is fixedly provided at the front end of the positioning cylinder 12, and a gear 17 that meshes with the gear ring 15 is provided at the output end of the third motor 16.

[0022] The third motor 16 (i.e. the core power source of the second drive assembly) fixed on the outside of the support plate 6 is started. The output end of the third motor 16 is equipped with a gear 17, and the front end of the positioning cylinder 12 is fixed with a gear ring 15 that meshes with the gear 17.

[0023] Therefore, when the third motor 16 is running, it will drive the positioning cylinder 12 to rotate stably around its own axis through the meshing transmission of the gear 17 and the gear ring 15 (the front end of the positioning cylinder 12 passes through the support plate 6 and is rotatably connected to the support plate 6, and the support plate 6 is vertically fixed at one end of the base 5 to provide support for the positioning cylinder 12).

[0024] As the positioning cylinder 12 rotates, it drives the outer winding cylinder to rotate synchronously, thereby gradually and evenly winding the stainless steel coil onto the winding cylinder, officially starting the winding operation.

[0025] Step 4: Automatic centering adjustment during the winding process: The upper end of the base plate 1 is provided with a sliding groove 7, and the lower end of the base 5 is provided with a slider that slides in cooperation with the sliding groove 7. The first drive assembly includes a first motor 9 and a side plate 8. The side plate 8 is fixed to both sides of the base plate 1 by screws. The first motor 9 is fixed to the outside of one of the side plates 8. The output end of the first motor 9 is provided with a first rotating shaft 10 that is inserted into the sliding groove 7. A first threaded rod 11 is fixedly provided on the first rotating shaft 10. The first threaded rod 11 passes through the slider and is threadedly connected to the slider. A control module is provided on the first motor 9. The control module is connected to the laser rangefinder 4 by an electrical signal. The cross-section of the sliding groove 7 is inverted T-shaped.

[0026] Throughout the winding operation, the laser rangefinder 4, which is fixed to one side of one of the support frames 2, is activated. Its output probe is located between the two guide rollers 3, which can capture the offset of the stainless steel coil in real time during the transmission process and convert the offset signal into an electrical signal and transmit it to the control module on the first motor 9.

[0027] After receiving the offset signal, the control module will precisely adjust the operating state of the first motor 9 according to the degree of offset. The first motor 9 is fixed on the outside of the side plates 8 on both sides of the base plate 1. The first rotating shaft 10 at its output end is inserted into the slide groove 7 at the upper end of the base plate 1. The first rotating shaft 10 is fixed with a first threaded rod 11, and the first threaded rod 11 passes through the slider at the lower end of the base 5 and is threadedly connected to the slider (the slider and the slide groove 7 are in sliding fit, and the cross section of the slide groove 7 is inverted T-shaped, which can prevent the slider from disengaging from the slide groove 7 and ensure smooth sliding).

[0028] When the first motor 9 is running, the first rotating shaft 10 drives the first threaded rod 11 to rotate synchronously, which in turn drives the slider to slide laterally along the slide groove 7. The slider drives the upper base 5 to move synchronously, and the base 5 drives the positioning cylinder 12 and the winding cylinder to adjust their lateral positions in real time through the support plate 6, so as to achieve automatic centering in the winding process of stainless steel coil and avoid winding defects caused by strip misalignment.

[0029] Through the rectangular cavity 18 and slot 19 inside the positioning cylinder 12, in conjunction with the second motor 14, second rotating shaft 24, second threaded rod 13, drive block 22, limit block 20 and other structures, the reverse thread characteristics of the second threaded rod 13 drive the two drive blocks 22 to move closer together. Then, through the contact transmission of the first inclined surface 23 and the second inclined surface 21, the limit block 20 extends out of the slot 19 and clamps the inner wall of the winding drum through the arc groove. The entire assembly process does not require additional clamping tools, has a high degree of automation, and the tight fit design between the drive block 22 and the rectangular cavity 18, and between the limit block 20 and the slot 19, can prevent the limit block 20 from moving or shifting, ensuring that the winding drum does not loosen during winding. This completely solves the problems of cumbersome assembly and unstable fixing of traditional winding shafts, and significantly shortens the assembly time.

[0030] The two support frames 2 symmetrically arranged on the upper end of the base plate 1, and the two guide rollers 3 symmetrically arranged between the support frames 2, can form a two-way guiding constraint on the stainless steel coil, effectively reducing the swaying and deviation of the strip during high-speed transmission. Meanwhile, the rotating connection design between the guide roller 3 and the support frame 2 can convert the sliding friction between the strip and the roller surface into rolling friction, reducing frictional damage to the strip surface. This not only protects the surface finish of the stainless steel coil but also ensures the stability of the strip's transmission path, providing a prerequisite for subsequent precise coiling.

[0031] Laser rangefinder sensor 4 (core detection element): Functional requirements: The offset of the stainless steel coil between the two guide rollers 3 is captured in real time, and a stable electrical signal is output to the control module. It needs to meet the requirements of high ranging accuracy (adapting to ±0.5mm centering accuracy), fast response speed (≤10ms), and high protection level (resistant to dust / small amount of coolant in the rolling workshop). At the same time, it needs to be compatible with the subsequent control module to avoid additional signal conversion links.

[0032] Recommended model: Keyence IL-1000 Series Laser Rangefinder Sensor 4 (Specific Model: IL-1050); Reasons for selection: Accuracy and responsiveness meet the standards: the measurement range is 0-50mm, the repeatability is ±0.01mm, and the linearity is ±0.03mm, which is far higher than the centering accuracy requirements of the equipment. It can accurately identify the slight deviation of the strip. The fastest response speed is 10μs, which can capture the instantaneous deviation of the strip caused by the fluctuation of the rolling tension in real time, avoid the centering lag caused by signal delay, and ensure timely centering adjustment.

[0033] First motor 9 (drives base 5 to move laterally, achieving automatic centering): Recommended model: Panasonic A6 series servo motor (specific model: MSMF042L1U2M) + matching driver (MADKT1505E); Reasons for selection: Precise positioning and torque adaptation: The motor has a rated power of 0.4kW and a rated torque of 1.27N・m. It is equipped with a 20-bit absolute encoder, and the position control accuracy can reach ±1 pulse (corresponding to a movement accuracy of ±0.01mm within the slide groove 7). It can achieve micro-adjustment of the lateral position of the positioning cylinder 12. The total weight of the components such as the base 5, support plate 6, and positioning cylinder 12 is about 50-80kg. When paired with a lead screw drive, the thrust can reach more than 5000N, which is sufficient to drive it to slide smoothly along the slide groove 7 without the risk of overload.

[0034] Excellent control coordination: The driver supports pulse control and analog control (can directly receive offset adjustment signals from the control module), and can realize closed-loop control of "sensor detection - motor response" through PLC. It can switch between forward and reverse directions flexibly and without commutation delay, and adapt to the bidirectional adjustment requirements of strip steel left and right offset.

[0035] Strong vibration resistance: The motor rotor is made of high-strength permanent magnet material, and the vibration acceleration during operation is ≤10m / s². It can adapt to the slight vibration when the winding equipment is working, avoid the base 5 from sliding and shifting due to vibration, and ensure stable centering accuracy.

[0036] Second motor 14 (drives drive block 22 to move closer and clamp the winding drum): Functional requirements: The second rotating shaft 24 is driven to rotate, and the two drive blocks 22 are driven to move closer together in the rectangular cavity 18 through the second threaded rod 13. It is necessary to meet the following requirements: sufficient torque (to push the limit block 20 to clamp the winding drum), controllable speed (to avoid clamping too fast and damaging the winding drum), and accurate positioning (to ensure that the drive blocks 22 move the same distance). At the same time, it is necessary to adapt to the compact installation space at the front end of the positioning cylinder 12.

[0037] Recommended model: Leadshine DM series two-phase stepper motor (specific model: 42HS40-1704) + matching driver (DM542); Reasons for selection: Positioning accuracy and speed controllable: The motor has a rated torque of 0.5 N·m and a step angle of 1.8° (which can be reduced to 0.01° after subdivision). When paired with the second threaded rod 13 with a pitch of 4 mm, the movement accuracy of the drive block 22 can reach ±0.005 mm, which can accurately control the extension length of the limit block 20 and avoid over-clamping or under-clamping. The driver supports speed adjustment from 0 to 1000 rpm and can be set to low-speed clamping (such as 100 rpm) to prevent the limit block 20 from rapidly impacting the inner wall of the winding drum and protect the winding drum and the limit block 20.

[0038] Cost and installation compatibility: The cost of the stepper motor + driver combination is lower than that of the servo motor. For non-continuous operation conditions such as "clamping and positioning", its start-stop stability fully meets the requirements and no additional encoder is needed. The motor body size is only 42mm, which can be directly fixed to the front end of the positioning cylinder 12 through the flange, which is compatible with the compact structure of the equipment and does not take up extra space.

[0039] The third motor 16 (drives the positioning cylinder 12 to rotate, realizing the winding of the coil): Recommended model: Siemens 1LE0 series three-phase asynchronous motor (specific model: 1LE0001-1DA23-3AA4) + worm gear reducer (model: RV063, reduction ratio 10:1); Reasons for selection: Torque and speed matching: The motor has a rated power of 1.5kW and a rated speed of 1430rpm. When paired with a reducer with a reduction ratio of 10:1, the output torque can reach 95.5N・m, which can easily drive the winding drum (including the largest diameter roll) to rotate stably and avoid "stalling" due to insufficient torque during winding. The speed can be adjusted from 0-143rpm (after reduction) through a frequency converter (such as Siemens MM440 series), which can adapt to different calendering line speeds of 200-500m / min and ensure consistent strip winding tension.

[0040] High durability and safety: The motor has an IP55 protection rating and an F-class insulation rating, allowing for long-term continuous operation in the calendering workshop (life ≥ 10,000 hours); the worm gear reducer has a self-locking function, which can prevent the winding drum from reversing due to gravity, avoid strip loosening, and improve the safety of winding operations.

[0041] Good transmission stability: The speed fluctuation of the asynchronous motor during operation is ≤0.5%. With the meshing transmission of gear 17 - gear ring 15 (transmission efficiency ≥90%), it can avoid the strip steel from being unevenly stretched or wrinkled due to the fluctuation of the winding speed, thus ensuring the quality of the finished coil.

[0042] Control module (core control element, coordinating the operation of various electrical components): Functional requirements: It receives the offset signal from the laser rangefinder sensor 4, analyzes it, and outputs control commands to the drivers of the three motors to realize automated closed-loop control of "detection-judgment-execution". It needs to meet the requirements of sufficient I / O interfaces (to connect various components), fast processing speed (to avoid command delay), support for multi-motor collaborative control, and facilitate later programming, debugging and fault diagnosis.

[0043] Recommended model: Siemens S7-1200 series PLC (specific model: 1214C DC / DC / DC) + analog input module (SM1231 AI 4x13bit). Reasons for selection: Interface and computing power adaptation: The PLC host comes with 14 digital inputs and 10 digital outputs (for controlling motor start and stop). When paired with the SM1231 analog module (4 inputs), it can directly connect to the analog signals of the laser rangefinder sensor 4 without the need for additional expansion modules. The CPU has a main frequency of 100MHz and an instruction execution speed of 0.1μs / basic instruction. It can quickly parse offset signals and output motor control instructions (response delay ≤10ms), avoiding lag in centering or clamping actions.

[0044] Flexible programming and control: Supports TIA Portal programming software, which allows for intuitive programming of closed-loop control logic (such as PID regulation) based on sensor detection and motor response, facilitating parameter optimization according to actual production needs; supports communication protocols such as PROFINET and RS485, enabling data interaction with servo drives and frequency converters, and real-time monitoring of motor speed, torque, and other operating statuses, facilitating equipment fault diagnosis and maintenance.
