A multi-head steel strip winding control system

Abstract

This invention provides a multi-head steel strip winding control system, including a main channel with multiple winding stations equipped with winding wheels along its length. The steel strip moves along the main channel, arranged from the outside to the inside and sequentially wound onto the winding wheels at each winding station. A redundant steel strip detection unit detects the amount of steel strip redundancy. When the redundancy exceeds a maximum redundancy threshold, the winding wheel speed is increased until the redundancy falls below a minimum redundancy threshold, at which point the speed is reduced back to the initial speed. As the steel strip passes through the main channel, it is wound directly onto multiple winding wheels in an outward-to-inward sequence, eliminating the need for rewinding via a rewinding machine and then rewinding via a layer winding machine, thus shortening production steps. Simultaneously, it keeps the steel strip in a relaxed state during winding, preventing excessively long redundant steel strips from drooping and contacting the ground, which could cause multiple narrow steel strips to knot or rub against the ground, affecting continuous production and product quality.

Description

Technical Field

[0001] This invention belongs to the field of flux-cored welding wire production technology, and in particular relates to a multi-head steel strip winding control system. Background Technology

[0002] In the production process of flux-cored welding wire, the steel strip raw material needs to be thinned into a wide steel strip through rolling. Then, it is cut along the length of the wide steel strip to process into multiple narrow steel strips. The narrow steel strips are then wound onto narrow I-beams by a rewinding machine, and then wound onto wide I-beams by a layer winding machine for later use. However, this process results in a long production process, a large production line area, low production efficiency, and requires more manpower to monitor the operation of the layer winding machine and the rewinding machine. Summary of the Invention

[0003] In view of this, the present invention aims to provide a multi-head steel strip winding control system to improve production efficiency.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0005] A multi-head steel strip winding control system, including

[0006] The main channel has multiple winding stations along its length. Each winding station is equipped with a winding wheel. Multiple steel strips move from one end of the main channel to the other end. Along the direction of the steel strip movement, the steel strips in the main channel, arranged from the outside to the inside, are wound sequentially onto the winding wheels of the winding stations.

[0007] The redundant steel strip detection unit is used to detect the redundancy of the steel strip caused by the speed difference between the release speed at the front end and the winding speed at the rear end during the winding process.

[0008] The speed control module increases the winding wheel speed when the steel strip redundancy exceeds the maximum redundancy threshold, and then reduces the winding wheel speed back to the initial speed when the redundancy is less than the minimum redundancy threshold.

[0009] Furthermore, when the amount of redundant steel strip exceeds the maximum threshold, the speed control module increases the speed of the winding wheel by 1 unit in the first second, and then increases the speed by 20% of the speed increase in the previous second every second thereafter.

[0010] Furthermore, when the amount of redundant steel strip is less than the minimum threshold, the speed control module reduces the speed of the winding wheel by 5 units per second until the speed of the winding wheel is reduced to the initial speed.

[0011] Furthermore, the redundant steel strip detection unit is provided with a drop groove on the side away from the main channel. Due to the difference between the front release speed and the rear winding speed, the redundant steel strip drops downward into the drop groove.

[0012] Furthermore, the redundant steel strip detection unit includes multiple proximity sensors, and each proximity sensor can control the speed of a winding wheel to increase or decrease through a speed control module. The redundant steel strip droops, and the proximity sensor can detect the distance between the drooping part of the steel strip and the proximity sensor. When the distance is less than the distance threshold, it is determined that the amount of redundant steel strip is greater than the maximum threshold. When the distance is greater than the threshold, it is determined that the amount of redundant steel strip is less than the minimum threshold.

[0013] Furthermore, the winding stations are respectively located on both sides of the main channel, and each winding station includes a deflection guide unit. Each deflection guide unit includes at least one deflection guide wheel, and the deflection guide wheel is placed between the steel strip corresponding to the winding station and the winding wheel of the winding station. The steel strip passes around the outer periphery of the deflection guide wheel and then winds onto the winding wheel.

[0014] Furthermore, a first twisting space for the steel strip is left between the end of the main channel near the redundant steel strip detection unit and the winding station closest to that end.

[0015] Furthermore, the deflection guide unit also includes a wiring assembly that can reciprocate along the axial direction of the take-up reel.

[0016] Furthermore, a traction platform that moves along the length of the main channel is provided on one side of the main channel, and the end of the steel belt can be placed inside the traction platform.

[0017] Furthermore, a truss is provided below the main channel, and steel strips are placed on the truss.

[0018] Compared with existing technologies, the multi-head steel strip winding control system described in this invention has the following advantages:

[0019] This invention employs multiple winding stations set along the main channel, allowing the steel strip to sequentially correspond to the multiple winding stations arranged along the length of the main channel as it passes through the main channel, from the outside to the inside. During the movement, it is directly wound onto multiple winding wheels, saving the process of winding the steel strip through a rewinding machine and then rewinding it through a layer winding machine, thus shortening the production steps. By using redundant steel strip length detection in conjunction with a speed control module, the steel strip can be wound up while remaining in a relaxed state, while also preventing the redundant steel strip in front from being too long and drooping down to contact the ground, which would cause multiple narrow steel strips to tangle or rub against the ground, affecting continuous production and product quality.

[0020] When the steel strip redundancy is large, the winding wheel is controlled to rotate at a uniform acceleration to wind up more steel strip. This avoids sudden acceleration that would cause the steel strip on the winding wheel to be suddenly tightened under inertia, thus making the tension of the steel strip on the winding wheel more consistent.

[0021] When the redundant steel strip falls below the minimum threshold, the winding wheel is slowed down to its initial speed to maintain redundancy in the steel strip before winding. This prevents the steel strip from becoming taut, which would result in excessive tension from the winding wheel, causing the steel strip to break or deform, thus improving product quality.

[0037] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] The multi-head steel strip winding control system described in this application includes

[0039] The main channel 1 has multiple winding stations 2 along its length. Each winding station 2 is equipped with a winding wheel 21. Multiple steel strips 4 move from one end of the main channel 1 to the other end. Along the direction of movement of the steel strips 4, the steel strips 4 arranged from the outside to the inside in the main channel 1 are wound onto the winding wheel 21 of the winding station 2 in sequence.

[0040] The redundant steel strip detection unit 3 is used to detect the redundancy of the steel strip 4 caused by the speed difference between the release speed at the front end and the winding speed at the rear end during the winding process.

[0041] The speed control module increases the speed of the take-up reel 21 when the redundancy of the steel strip 4 exceeds the maximum redundancy threshold, and then reduces the speed of the take-up reel 21 back to the initial speed when the redundancy is less than the minimum redundancy threshold.

[0042] After the wide steel strip 4 is slid-cut into narrow steel strip 4 by the slitting machine, it enters the main channel 1 through the redundant steel strip detection unit 3 and moves along the length of the main channel 1. The winding station 2 can be arranged along the length of the channel, and the winding station 2 corresponds one-to-one with the narrow steel strip 4. After each narrow steel strip 4 is guided from the main channel to the corresponding winding station 2, it is wound on the winding wheel 21. During normal operation, the I-beam of the wide steel strip 4 releases the wide steel strip 4 at a preset speed. After being processed by the slitting machine, it is wound and stored by the winding wheel 21 which rotates at the initial speed. The redundant steel strip detection unit 3 includes a proximity sensor 33, which can be a proximity switch or a laser rangefinder, etc. The proximity sensor 33 is set at a preset position. The redundant steel strip 4 hangs down under its own weight. The position of the proximity sensor 33 can measure the distance of the hanging angle of the steel strip 4 or the lowest point of the parabola formed by the hanging. When the measured distance is less than the preset minimum threshold, it is determined that the redundancy of the steel strip 4 is greater than the maximum redundancy threshold. When the measured distance is greater than the preset maximum value, the redundancy of the steel strip 4 is less than the minimum redundancy threshold.

[0043] Each proximity sensor 33 corresponds to a winding station 2, enabling the proximity sensor 33 to control the speed of a winding wheel 21 by adjusting the speed through the speed control module. The redundant steel strip 4 droops, and the proximity sensor 33 can detect the distance between the drooping part of the steel strip 4 and the proximity sensor 33. When the distance is less than the distance threshold, it is determined that the amount of redundant steel strip 4 is greater than the maximum threshold. When the distance is greater than the threshold, it is determined that the amount of redundant steel strip 4 is less than the minimum threshold.

[0044] For example, the proximity sensor 33 can be placed on the ground in the middle of the redundant steel strip 4 section to detect the distance between the lowest point of the redundant drooping of the steel strip 4 and the ground. The minimum distance is set to 15cm above the ground from the lowest point of the drooping of the steel strip 4, and the maximum distance is set to 18cm from the ground. In this embodiment, the proximity sensor 33 is placed on the side of the drooping part of the steel strip 4. It is used to measure the drooping angle of the steel strip 4. When the redundancy of the steel strip 4 is large, the redundant part of the steel strip 4 is heavier, which increases the angle between the parabola formed by the drooping of the steel strip 4 and the horizontal plane. The proximity sensor 33 is placed on the outside of the redundant part of the steel strip 4. As the drooping angle of the steel strip 4 increases, one side of the drooping steel strip 4 gradually approaches the proximity sensor 33. This is to avoid the steel strip 4 from contacting the proximity sensor 33 during excessive drooping, which could damage the proximity sensor 33.

[0045] The speed control module communicates with the redundant steel strip detection unit 3 via wired or wireless means, enabling the speed control module to receive signals from the steel strip 4 detection unit. When the redundancy of the steel strip 4 exceeds the maximum redundancy threshold, the proximity sensor 33 sends a signal to the speed control module, causing the speed control module to control the winding wheel 21 to accelerate, thereby increasing the winding speed of the steel strip 4 and reducing its redundancy. When the redundancy of the steel strip 4 is less than the minimum redundancy threshold, the proximity sensor 33 stops sending signals to the speed control module, and the speed control module controls the winding wheel 21 to gradually decelerate to its initial speed. The specific communication connection method can be wired transmission, Bluetooth transmission, or other existing technologies known to those skilled in the art; the control of the winding wheel 21 by the speed control module can also be performed using existing technologies known to those skilled in the art, and will not be elaborated further here.

[0046] Multiple winding stations 2 are set along the main channel 1, so that the steel strip 4 can be wound directly onto multiple winding wheels 21 in sequence from the outside to the inside when passing through the main channel 1. This saves the process of winding the steel strip 4 through a rewinding machine and then rewinding it through a layer winding machine, shortening the production steps. By detecting the length of the redundant steel strip 4 and coordinating with the speed control module, the steel strip 4 can be wound up in a relaxed state, while avoiding the redundant steel strip 4 from hanging down and contacting the ground, which would cause multiple narrow steel strips 4 to get tangled or rub against the ground, affecting continuous production and product quality.

[0047] In this embodiment, when the amount of redundant steel strip 4 is greater than the maximum threshold, the speed control module increases the speed of the take-up reel by 1 unit in the first second, and then increases the speed by 20% of the increase in the previous second every second. For example, when it is necessary to increase the take-up speed of steel strip 4, with the initial speed of take-up reel 21 as 100%, the speed is increased to 101% in the first second, 101.2% in the second second, 101.44% in the third second, and so on. If the initial take-up speed is 20 M / s, then the speed is increased to 20.2 M / s in the first second, 20.24 M / s in the second second, and 20.288 M / s in the third second (generally, two decimal places are sufficient). In this embodiment, the maximum increase to the speed is 150%. When the amount of redundant steel strip 4 is less than the minimum threshold, the speed control module decreases the speed of the take-up reel by 5 units per second until the speed of take-up reel 21 is reduced to the initial speed. If the speed of the winding wheel 21 after acceleration is 120%, then the speed will decrease to 115% in the first second, 110% in the second second, and so on until the speed decreases to 100%, thus completing the deceleration process.

[0048] The redundant steel strip detection unit 3 has a drop groove 6 on the side away from the main channel 1. Due to the difference between the front release speed and the rear winding speed, the redundant steel strip 4 drops downward into the drop groove 6. This is to prevent the redundant steel strip 4 from drooping to the ground and causing it to become entangled and knotted under the action of curling stress.

[0049] In this embodiment, the redundant steel strip detection unit 3 further includes a roller 31, a drooping position support rod 32, and a proximity sensor 33. The drooping position support rod 32 is placed below the roller 31 and along the movement direction of the steel strip 4. The roller 31 is located in front of the drooping position support rod 32. The probe of the proximity sensor 33 is placed between the roller 31 and the drooping position support rod 32. The steel strip 4 rests on the roller 31, and the probe faces the direction of the steel strip 4.

[0050] It is understood that in this embodiment, the proximity sensor 33 can be a contact sensor, or a laser rangefinder or other sensor capable of determining the distance between the steel strip 4 and its own probe. The threshold can be the distance between the steel strip 4 in its natural state (hanging down) and the sensor probe, or the distance between the sensor probe and the steel strip 4 after the steel strip 4 is taut. Those skilled in the art can adjust and set this according to the needs of the equipment site.

[0051] In this embodiment, there are multiple proximity sensors 33. Specifically, the number of proximity sensors 33 is the same as the number of narrow steel strips 4 after slitting, so that the proximity sensors 33 correspond one-to-one with the narrow steel strips 4. A partition 363 is provided between each pair of adjacent sensors, and a steel strip channel 365 is left between the two partitions 363, so that the mechanism can be used to wind up multiple thin steel strips 4. In this embodiment, the wide steel strip 4 is cut into multiple thin steel strips 4 arranged side by side by the slitting mechanism. Then, each thin steel strip 4 is placed in the steel strip channel 365 so that each thin steel strip 4 can be wound into the winding mechanism, thereby improving the detection accuracy during the winding process of the steel strip 4.

[0052] The steel strip channel 365 has a separation sleeve 364. Each pair of adjacent partitions 363 abut against the two end faces of the separation sleeve 364, thereby separating the partitions 363 and preventing changes in the spacing between the partitions 363, which would cause wear on the steel strip 4.

[0053] Specifically, the redundant steel strip detection unit 3 further includes a fixed frame 35 and a quick-change frame 36. The fixed frame 35 is connected to a main crossbeam 351. Support blocks 352 are fixed at both ends of the main crossbeam 351, and the drooping position support rod 32 is fixed to the support block. The proximity sensor is fixed on the main crossbeam. In this embodiment, the sensor is arranged at an angle so that the sensor probe measures the distance of the drooping steel strip 4. The quick-change frame 36 includes a connecting block 361, a connecting rod 362 fixedly connected to the connecting block 361, and the connecting rod 362 passing through a partition 363. The partition 363 has a dividing part 3631 and a positioning part 3632. The end of the positioning part 3632 away from the dividing part 3631 has a positioning fork 3633. The main crossbeam 351 is placed inside the positioning fork 3633. The connecting block 361 and / or the fixing frame 35 each have oppositely arranged receiving grooves 3611. The end of the connecting shaft is placed inside the receiving groove 3611. The receiving grooves 3611 are formed on the top surface of the fixing frame 35 and / or the lower surface of the connecting block 361. The two sides of the connecting block 361 are fixedly connected to the fixing frame 35 by bolts, so that the receiving grooves 3611 of the fixing frame 35 and the connecting block 361 are oppositely arranged, and the two receiving grooves 3611 form a circle. The connecting rod 362 is placed inside the receiving groove 3611. The separating sleeve 364 is sleeved on the connecting shaft. After prolonged operation, the redundant steel strip detection unit 3 may experience friction due to prolonged friction of the steel strip 4 on the partition 363. By cooperating with the connecting block 361 and the fixing frame 35, multiple partitions 363 can be removed as a whole and replaced. The spacing between the partitions 363 is determined by the separating sleeve 364 to prevent the partitions 363 from shifting during installation or operation and affecting the steel strip 4 in the steel strip channel 365.

[0054] In this embodiment, each steel strip channel 365 is provided with a fixing block 38, and each partition 363 is placed between two fixing blocks 38, with the two side surfaces of the partition 363 respectively abutting against the opposite side surfaces of the two fixing blocks 38. This fixes the bottom of the partition 363, preventing vibration caused by friction of the steel strip 4. The fixing block 38 has a through hole in the middle, through which the main crossbeam 351 passes. Those skilled in the art can fix the fixing block 38 by screwing it with a set screw and tightly abutting it against the main crossbeam 351; or, a clamping groove is provided in the fixing block 38, with the through hole communicating with the clamping groove. A bolt passes through the clamping groove and is screwed to a nut. By rotating the bolt, the clamping groove is tightened, and the main crossbeam 351 is clamped by the clamping groove and the through hole.

[0055] Each fixing block 38 is provided with a support frame 39, which includes a fixing part 391 and a supporting part 392. The fixing part 391 is fixedly connected to the fixing block 38, and the supporting part 392 extends obliquely into the steel strip channel 365. The proximity sensor 33 is fixedly connected to the supporting part 392. A bolt passes through the fixing part 391 to fix the support frame 39 to the fixing block 38. The supporting part 392 is connected to one end of the fixing part 391 and extends obliquely upward into the steel strip channel 365. The supporting part 392 is plate-shaped. The proximity sensor 33 is screwed onto the supporting plate by its own threads and a nut. The supporting plate keeps the proximity sensor 33 fixed in a preset position.

[0056] The winding stations 2 are respectively located on both sides of the main channel 1, and each winding station 2 includes a deflection guide unit 5. Each deflection guide unit 5 includes at least one deflection guide wheel 51, and the deflection guide wheel 51 is placed between the steel strip 4 corresponding to the winding station 2 and the winding wheel 21 of the winding station 2. In this embodiment, the deflection guide wheel is horizontally arranged, and the outer periphery of the deflection guide wheel 51 is perpendicular to the horizontal plane. A first twisting space 11 is left between the end of the main channel 1 near the redundant steel strip detection unit 3 and the winding station 2 closest to that end. The horizontally arranged narrow steel strip 4 can twist around its own center within the first twisting space 11, so that the part of the steel strip 4 near the deflection guide wheel 51 is perpendicular to the horizontal plane, thereby rotating around the outer periphery of the deflection guide wheel 51. After passing the deflection guide wheel 51, the steel strip 4 moves away from the channel, so that after passing the outer periphery of the deflection guide wheel 51, the steel strip 4 is wound around the winding wheel 21. In this embodiment, the take-up reel is vertically arranged, and the deflection guide unit 5 further includes a wiring assembly 52, which can reciprocate along the axial direction of the take-up reel 21. Specifically, the wiring assembly 52 is positioned above the take-up reel 21, and a second twisting space 53 exists between the wiring assembly 52 and the deflection guide reel 51. The steel strip 4 can rotate around its own centerline within the second twisting space 53, causing the portion of the steel strip 4 near the wiring assembly 52 to twist to a horizontal state. The wiring assembly 52 includes multiple guide wheels. After the steel strip 4 passes over the multiple guide wheels, its internal stress is eliminated, and it is in a posture that allows it to move vertically, enabling the steel strip 4 to wind around the take-up reel. The multiple guide wheels of the wiring assembly 52 are mounted on a frame, which is slidably connected to a slide rail arranged along the axial direction of the take-up reel. The frame is also screwed to a lead screw, and the rotation of the lead screw is controlled by a motor, causing the wiring assembly 52 on the frame to move axially along the slide rail, so that the steel strip 4 is evenly wound around the take-up reel for use in subsequent steps.

[0057] A traction platform is provided on one side of the main channel 1, moving along the length of the main channel 1. The end of the steel strip 4 can be placed inside the traction platform. Specifically, the traction platform moves along the main channel 1 by rotating the lead screw driven by a motor through slide rails and lead screws arranged along the length of the main channel 1. A truss is provided below the main channel 1, and the steel strip 4 rests on the truss. The traction platform is positioned above the main channel 1. Before processing and production, the ends of the slit narrow steel strip 4 are bundled and then placed on the traction platform. The traction platform pulls the steel strip 4 across the main channel 1, so that the operator can pull the steel strip 4 from one end of the main channel 1 to the other, saving the time for the narrow steel strip 4 to pass through the main channel 1. This also makes it easier for the worker to wind the steel strip 4 onto the corresponding take-up reel 21. Alternatively, the ends of two narrow steel strips 4 arranged opposite each other on the main channel 1 can be placed on the traction platform, and then the steel strip 4 can be transported to the corresponding positions through multiple movements of the traction platform, so that the ends of the steel strip 4 move to the corresponding take-up station.

[0058] In this embodiment, each winding station 2 is equipped with a spare wheel. When the steel strip 4 is fully wound on the winding wheel 21, the spare wheel replaces the position of the winding wheel 21 to continue winding the steel strip 4, thus avoiding equipment downtime and affecting production efficiency. The specific method of replacing the winding wheel 21 with the spare wheel is existing technology and will not be described in detail here. Operators use a flatbed cart or similar device to remove the fully wound winding wheel 21 and transport it to the next processing station, and install the empty spare wheel in the preset position at the winding station 2.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
