Description

Technical Field

[0001] This invention relates to the field of sheet metal processing technology, and in particular to a method and apparatus for continuous recycling of edge wires from stainless steel sheets. Background Technology

[0002] Stainless steel sheets are widely used in many fields such as home appliances, construction, food processing, and precision instrument manufacturing due to their excellent corrosion resistance, high strength, and good surface gloss.

[0003] Currently, in the production process of stainless steel sheets, fixed-width slitting equipment is typically used to cut the sheets to obtain the finished width required by the production order. A typical fixed-width slitting machine is equipped with a feeding assembly, a conveying assembly, a cutting assembly, and an edge wire rewinding assembly. The general process is as follows: the feeding assembly stably unwinds and discharges the stainless steel sheet coil; the conveying assembly smoothly transports the unwound sheet to the cutting assembly; the cutting assembly precisely slits the sheet according to preset finished width parameters; and the edge wire generated during the slitting process is collected by the edge wire rewinding assembly, thus completing the fixed-width slitting and edge wire processing, enabling continuous sheet production.

[0004] Regarding the aforementioned technologies, the edge wire winding mechanism of existing stainless steel sheet width-cutting equipment is mostly fixed or can only achieve rotational winding. It cannot adjust its horizontal position according to the winding progress to achieve zoned winding, which causes the edge wire to easily become concentrated and wrapped in a single section of the winding shaft, resulting in uneven edge wire winding and reduced edge wire winding efficiency. Summary of the Invention

[0005] To address the technical problem that the edge wire winding mechanism in existing stainless steel sheet width-cutting equipment cannot adjust its horizontal position according to the winding progress, which easily leads to concentrated entanglement of edge wires and uneven winding, this invention provides a method and apparatus for continuous recovery of edge wires from stainless steel sheets.

[0006] In a first aspect, the present invention provides a method for continuous recycling of edge wires from stainless steel sheets, employing the following technical solution: A method for continuous recycling of edge wires from stainless steel sheets includes: In response to the feeding signal, the current position of the board and the preset feeding speed are obtained; Determine the lifting time corresponding to the lifting component based on the current position of the board and the material conveying speed; Obtain the current board cutting parameters, and control the cutting and slitting components to perform movement operations according to the current board cutting parameters; When the material falls into the preset cutting completion area, a manual guidance signal is output; Real-time acquisition of winding image information; The current winding edge wire features are determined based on the winding image information, thereby determining the current winding edge wire width; The limiting parameters of the limiting support column are determined based on the current winding edge wire width, and the limiting support column is controlled to perform the limiting support column movement operation according to the limiting support column limiting parameters; The take-up area number is determined based on the take-up image information, and the current take-up area is determined based on the take-up area number; Determine the movement parameters of the rotating winding mechanism based on the current winding area, execute the winding mechanism movement operation according to the rotation parameters, and obtain the current number of winding rotations; If the current number of winding rotations reaches the preset effective rotation threshold, the current winding area is re-determined based on the winding area number to determine the movement parameters of the winding mechanism, and the winding mechanism movement operation is executed according to the movement parameters of the winding mechanism, while the current number of winding rotations is reset.

[0007] By adopting the above technical solution, upon receiving the feeding signal, the system acquires the real-time position of the current board and the pre-set feeding speed. Based on this, the lifting time of the lifting component is calculated to ensure that the board can smoothly and accurately enter the next processing stage. Subsequently, the cutting component is controlled to move according to the acquired current board cutting parameters, thereby achieving fixed-width cutting of the board. When the board enters the cutting completion area, the system will promptly output a manual guidance signal so that the operator can wrap the cut and separated board waste edges with the rotating winding mechanism. During the winding process, the width of the current winding edge is determined by analyzing the image information. Based on this width, the system determines the limit parameters of the limit support column and controls the limit support column to move according to these parameters to ensure the neatness of the edge edges during the winding process. At the same time, the winding area number is determined based on the winding image information, thus identifying the current winding area. The movement parameters of the rotating winding mechanism are determined based on the current winding area, controlling its movement operation and acquiring the current number of winding rotations in real time. If the current number of winding rotations reaches the effective rotation threshold, the system will redetermine the current winding area based on the winding area number, execute the winding mechanism movement operation again, and reset the current number of winding rotations, thereby improving the uniformity of edge wire recovery of the board and increasing the recovery efficiency.

[0008] Optionally, it also includes a method for performing the movement operation of the limit support column, the method comprising: When the current winding area is updated, the winding edge tilt angle is determined based on the current winding edge characteristics and the current winding area. If the tilt angle of the winding edge does not fall within the preset baseline winding angle range, determine the sliding parameters of the limit support column to perform the movement operation of the limit support column.

[0009] By adopting the above technical solution, when the current winding area is updated, the system integrates the characteristics of the current winding edge wire and the newly determined position information of the current winding area to calculate the tilt angle of the winding edge wire when it enters the winding mechanism. If the calculated tilt angle of the winding edge wire exceeds the reference winding angle range, it indicates that the edge wire may have shifted or tilted during the winding process, which will affect the uniformity of the winding. At this time, the system will calculate and determine the sliding parameters of the limit support column based on the degree of deviation between the tilt angle and the reference angle range, and then control the limit support column to perform the movement operation according to these parameters, thereby correcting the direction of the edge wire in real time, ensuring that the edge wire can enter the winding mechanism at the correct angle, and further improving the uniformity of edge wire winding.

[0010] Optionally, methods for determining the sliding parameters of the limit support column include: The winding angle deviation value is determined based on the winding edge inclination angle and the reference winding angle range; The sliding parameters of the limit support column are determined by looking up the preset angle correction table based on the winding angle deviation value.

[0011] By adopting the above technical solution, the winding angle deviation is first calculated by comparing the tilt angle of the winding edge wire with the preset benchmark winding angle range. Based on this deviation, an angle correction table is consulted. This table pre-stores the sliding parameters of the limiting support column corresponding to different angle deviation values. This method allows for the rapid determination of specific parameters such as the required sliding distance and direction of the limiting support column, effectively ensuring the accuracy of the edge wire winding angle.

[0012] Optionally, it also includes a method for performing the rotation operation of the limit support column, the method comprising: Real-time acquisition of image information of the limit support column; Determine the current wear surface of the limit support column based on the image information of the limit support column; Determine the amount of wear and indentation of the limit support column based on the current wear surface of the limit support column; When the wear and indentation of the limiting support column falls within the preset abnormal wear and indentation range, the effective wear surface of the limiting support column is determined based on the image information of the limiting support column. When there is a wear surface of the effective limit support column, the rotation parameters of the limit support column are determined based on the current wear surface of the limit support column and the wear surface of the effective limit support column; The rotation operation of the limit support column is executed based on the rotation parameters of the limit support column.

[0013] By employing the above technical solution, image analysis technology is used to identify and determine the wear surface of the current limiting support column in contact with the edge wire. The wear indentation amount of the limiting support column is calculated based on the image characteristics of this wear surface. When the calculated wear indentation amount falls within the abnormal wear indentation range, it means that the currently contacting wear surface is excessively worn, potentially affecting the limiting effect on the edge wire. In this case, based on the image information of the limiting support column, the system searches for an effective limiting support column wear surface with a smaller wear indentation amount that still meets the limiting accuracy requirements in other circumferential areas not in contact with the edge wire. If an effective wear surface is successfully identified, the rotation parameters, such as the required rotation angle and direction of the limiting support column, are calculated by comparing the positional difference between the current wear surface and the effective wear surface in the circumferential direction of the limiting support column. Finally, based on these rotation parameters, the limiting support column is controlled to perform a rotation operation, switching the effective wear surface to the working position in contact with the edge wire, thereby restoring the normal limiting function of the limiting support column and extending its service life.

[0014] Optionally, it also includes a method for performing the lifting operation when there is no effective limit support column wear surface, the method comprising: When there is no effective limit support column wear surface, the vertical effective limit support column wear surface is determined based on the limit support column image information. When there is a wear surface on the vertical effective limit support column, the lifting parameters of the limit support column are determined based on the wear surface of the vertical effective limit support column and the current wear surface of the limit support column. Perform the lifting and lowering operation according to the lifting and lowering parameters of the limit support column.

[0015] By adopting the above technical solution, when the system determines that there is no effective wear surface for the limiting support column, that is, when all horizontal circumferential areas of the limiting support column have experienced wear exceeding the allowable range and cannot be switched to a usable wear surface by horizontal rotation, the system will further search, based on the image information of the limiting support column, in its vertical direction (i.e., the height direction of the limiting support column) for a vertically effective wear surface with a small amount of wear indentation that still meets the limiting accuracy requirements. If such a vertically effective wear surface is successfully identified, the system will compare the position of the current wear surface of the limiting support column in contact with the edge wire in the vertical direction with the position of this vertically effective wear surface to calculate the required lifting distance and direction of the limiting support column. Subsequently, the system controls the limiting support column to perform a lifting operation, adjusting the vertically effective wear surface to the working height in contact with the edge wire. Thus, even when the horizontal wear is severe, the effective limiting function of the limiting support column can be maintained by adjusting its position in the vertical direction, further extending its overall service life and reducing the replacement frequency.

[0016] Optionally, it also includes a method for performing a cleaning operation on the limit support column, the method comprising: Based on the current characteristics of the wound edge yarn, the suspected impurity area of ​​the edge yarn is identified; When there is a suspected impurity area for edge wires, the current impurity position is determined based on the suspected impurity area for edge wires. Obtain the position of the limit support column, and determine the current distance based on the current impurity position and the limit support column position; Obtain the current winding edge wire moving speed and impurity coverage area, and determine the inward winding time and return time of the limit support column based on the current winding edge wire moving speed and current distance; Determine the current edge wire winding angle based on the image information of the limit support column; Based on the current edge wire winding angle and the preset vertical edge wire winding angle, the inward parameters of the limit support column are determined. The inward winding time and return time of the limit support column are combined to generate a limit support column cleaning plan. The limit support column cleaning operation is then performed according to the limit support column cleaning plan.

[0017] By adopting the above technical solution, once a suspected impurity area on the edge wire is detected, the system uses image recognition technology to determine the specific location of the impurity on the edge wire. Simultaneously, the real-time position of the limiting support column is acquired, and the distance between the current impurity location and the limiting support column is calculated. Combining the current moving speed of the wound edge wire and the coverage area of ​​the impurity, the system can calculate the time the limiting support column needs to retract in advance and the time it needs to return to its original position after the impurity passes. Furthermore, the specific parameters for the retraction of the limiting support column are determined based on a preset vertical edge wire winding angle. Finally, by integrating the retraction parameters, retraction time, and return time of the limiting support column, a complete decontamination scheme for the limiting support column is generated. This scheme controls the limiting support column to retract in time before the impurity arrives and to quickly return to its original position after the impurity passes, effectively removing the impurity through contact with the limiting support column and improving the subsequent utilization rate of the waste material.

[0018] Optionally, it also includes a method for performing a limit support column avoidance operation when the wear and indentation of the limit support column does not fall within the range of no wear and indentation, the method including: The avoidance time and return time of the limit support column are determined based on the current winding edge wire moving speed and current distance. Determine the avoidance parameters of the limit support column based on the current edge wire winding angle; Based on the limit support column avoidance parameters, the limit support column avoidance time and the limit support column return time are combined to generate a limit support column avoidance plan, and the limit support column avoidance operation is executed according to the limit support column avoidance plan.

[0019] By adopting the above technical solution, when the wear and indentation of the limiting support column is not within the range of no wear and indentation, it means that its surface has already experienced a certain degree of wear. If it continues to contact the edge wire, the unevenness of the worn area may cause deviation in the winding of the edge wire or scratch the edge wire. At this time, the system will calculate the avoidance time when the limiting support column needs to start the avoidance operation, as well as the return time to the working position after the avoidance is completed. At the same time, combined with the current edge wire winding angle, the system determines the avoidance parameters such as the direction and distance that the limiting support column needs to move during the avoidance process. Subsequently, the system controls the limiting support column to temporarily avoid contact with the edge wire.

[0020] Secondly, the present invention provides a continuous stainless steel sheet edge wire recycling device, which adopts the following technical solution: A continuous stainless steel sheet edge wire recycling device, applied to the continuous stainless steel sheet edge wire recycling method described above, includes a feeding component, a conveying component, a cutting and sliding component fixedly connected to the conveying component, an edge wire winding and limiting component slidably connected to the conveying component, and a winding component fixedly connected to the conveying component. The feeding assembly includes a feeding base, a roll support fixedly connected to one end of the feeding base, and a plate drive assembly fixedly connected to one side of the feeding base. The plate drive assembly drives the stainless steel plate roll located on the roll support to rotate so as to realize the discharge of the plate. The conveying assembly includes a conveying base, a lifting assembly fixedly connected to the conveying base, a conveying roller group rotatably connected to the inner wall of the conveying base, a guide roller rotatably connected to the inner wall of the conveying base, a first guide plate fixedly connected to the conveying base, and a second guide plate fixedly connected to the outer wall of the conveying base.

[0021] By adopting the above technical solution, the feeding assembly provides stable support for the stainless steel sheet coil through the coil support base, while the sheet drive assembly provides power to drive the sheet coil to rotate and achieve continuous output. The lifting assembly in the conveying assembly can lift the sheet in a timely manner according to the position and conveying speed, ensuring a smooth transition of the sheet to the conveying roller group. The conveying roller group supports and conveys the sheet, while the guide rollers provide initial guidance for the conveying direction of the sheet.

[0022] Optionally, the cutting and slitting assembly includes a cutting base fixedly connected to the outer wall of the feeding base, a cutting drive mechanism fixedly connected to one end of the cutting base, a cutting connecting shaft fixedly connected to the output shaft of the cutting drive mechanism, and a cutting mechanism rotatably connected to the end of the cutting connecting shaft away from the cutting drive mechanism. The cutting drive mechanism drives the cutting mechanism to move to the corresponding position to cut the board according to the current board slitting parameters.

[0023] By adopting the above technical solution, the cutting and slitting assembly achieves a stable connection with the material feeding base through the cutting base, ensuring structural stability during the cutting process. The cutting drive mechanism, as the power source, drives the cutting mechanism to move via the cutting connecting shaft. While transmitting power, the cutting connecting shaft ensures the trajectory accuracy of the cutting mechanism during movement, enabling it to move to the position set by the current sheet metal slitting parameters.

[0024] Optionally, the edge yarn winding limiting assembly includes a limiting base, a limiting worktable slidably connected to one side of the limiting base, a movable plate fixedly connected to one end of the limiting worktable, a rotating mechanism slidably engaged with and rotatably connected to the movable plate, a limiting support column fixedly connected to the rotating mechanism, and a limiting movable seat fixedly connected to the side of the limiting worktable away from the limiting base. The side of the limiting movable seat away from the limiting worktable is slidably connected to the second guide plate; The winding assembly includes a winding base, a drive shaft slidably connected to the winding base, and a rotating winding mechanism rotatably connected to one end of the drive shaft away from the winding base. The rotating winding mechanism rotates to wind up the edge wires of the sheet material after it has been cut by the cutting and slitting assembly.

[0025] By adopting the above technical solution, the edge wire winding and limiting assembly achieves stable support for the overall structure through the limiting base. The limiting worktable can slide on one side of the limiting base, thereby driving the entire limiting mechanism to adjust its position. The moving plate is fixedly connected to one end of the limiting worktable, and the rotating mechanism is both slidingly engaged and rotatably connected to the moving plate. This allows the limiting support column to not only slide horizontally with the rotating mechanism but also rotate itself through the rotating mechanism, so as to switch different wear surfaces according to the edge wire winding situation. The limiting support column directly contacts the winding edge wire, playing a limiting and guiding role. The drive shaft is slidably connected to the winding base, allowing the rotating winding mechanism to adjust its horizontal position on the winding base according to changes in the winding area, to adapt to the winding requirements of edge wire at different positions. The rotating winding mechanism is rotatably connected to the end of the drive shaft away from the winding base, and achieves rotational motion under the drive of the drive device, thereby winding and coiling the edge wire of the board material cut and separated by the cutting and slitting assembly, completing the edge wire recycling process.

[0026] In summary, the present invention has at least one of the following beneficial technical effects: This achieves even winding of edge wires in different sections, avoiding the edge wires from being concentrated and wrapped in a single section of the winding shaft, effectively improving the winding efficiency and winding regularity of edge wires. The intact working surface of the limit support column can be switched by rotating and raising / lowering, which can greatly extend the service life of the limit support column and reduce the cost of equipment replacement and maintenance. It can clean or protect the surface of the edge wires by friction, avoiding scratches on the high-quality stainless steel sheet by impurities and abrasive working surfaces, and ensuring the surface quality of the finished sheet.

[0037] Based on the same inventive concept, embodiments of the present invention provide a method for continuous recycling of edge wires from stainless steel sheets.

[0038] Reference Figure 5 A method for continuous recycling of edge wires from stainless steel sheets, comprising: Step S1: In response to the feeding signal, obtain the current position of the board and the preset feeding speed.

[0039] The feeding signal refers to the instruction signal received by the equipment that feeding can begin and the production line is ready to start. Specifically, it is the electrical signal issued by the pressure sensor installed on the coil support 12 after detecting that the steel coil has been placed in place and feeding is completed.

[0040] The current board position refers to the real-time movement of the board on the production line. This position data is obtained by capturing real-time image information of the production line area using cameras, combining this with edge recognition algorithms to extract the board's edge features, and then tracking and locating the front end of the board in real time. The production line area refers to the entire board conveying and processing section starting from the discharge end of the feeding component 1, sequentially passing through the conveying component 2 and the cutting and slitting component 3.

[0041] The conveying speed refers to the linear speed at which the conveying roller group 23 feeds the plate forward, that is, the conveying speed of the plate.

[0042] Step S2: Determine the lifting time corresponding to the lifting component 22 based on the current position of the board and the material conveying speed.

[0043] The lifting time refers to the point in time when the lifting shaft 222 controls the lifting plate 223 to lift, as shown in the reference. Figure 2The lifting assembly 22 is located between the feeding assembly 1 and the conveying assembly 2. Since the ends of stainless steel coils commonly exhibit warping, camber, or creases, and the sheets retain a curl memory curvature, if they directly enter the conveying assembly 2 after uncoiling, the ends will be scratched or even damaged on the leveling roller surface due to hard contact and excessive local stress. In this case, the lifting assembly 22 can raise the end of the sheet to a height level with the slitting knife inlet, acting like a "bridge" to stably support the warped end, preventing direct contact with the equipment below and avoiding scratches on the idler roller surface. Furthermore, a camera located below the lifting plate 223 can capture images of the bottom surface of the sheet to analyze its defects, prevent damage to the idler rollers, and allow for timely manual intervention.

[0044] Step S3: Obtain the current board cutting parameters, and control the cutting component 3 to perform the movement operation according to the current board cutting parameters.

[0045] The current sheet metal cutting parameters refer to the cutting parameters determined by manually pre-inputting the target finished product width based on the sheet metal on the conveying component 2. The target finished product width refers to the nominal width of the qualified finished sheet metal obtained after cutting, which is manually pre-inputted according to the production order or process requirements.

[0046] The movement parameters of the cutting and slitting component 3 refer to the distance parameters between the cutting execution ends of the two cutting mechanisms 34, which are determined manually based on the target finished product width pre-input on the sheet material on the conveying component 2.

[0047] The moving operation refers to the positioning adjustment action in which the cutting drive mechanism 32 drives the cutting connecting shaft 33 to move axially along the first guide hole to adjust the relative distance of the cutting mechanism 34 so that the cutting distance is consistent with the width of the target finished product.

[0048] Step S4: When the material falls into the preset cutting completion area, output a manual guidance signal.

[0049] The cutting completion area refers to the preset space range where the end of the board will leave the cutting area after the cutting and slitting component 3 has completed the slitting operation. Specifically, the area is defined by a photoelectric sensor set 50 to 100 mm behind the exit end of the cutting and slitting component 3. When the front end of the board passes the sensor, it is determined that the board position has fallen into the cutting completion area.

[0050] The manual guidance signal refers to the prompt signal issued by the sound and light alarm device, which is intended to remind on-site operators to promptly insert the slit waste board material into the limiting hole and wind it onto the winding shaft of the winding assembly 5.

[0051] Step S5: Acquire image information of the winding process in real time.

[0052] The take-up image information refers to real-time image data acquired by an industrial camera positioned between the edge wire take-up limit assembly 4 and the take-up assembly 5, including the current lateral position of the take-up shaft, the orientation of the take-up shaft axis, and the current take-up landing point of the edge wire. The take-up shaft refers to the shaft component in the rotating take-up mechanism 53 used to directly wind and collect the edge wire.

[0053] The current lateral position of the take-up spool refers to the real-time coordinate position of the take-up spool axis in the horizontal direction within the industrial camera image coordinate system (i.e., how much the take-up spool has moved to the left or right).

[0054] The orientation of the take-up reel axis refers to the direction and tilt of the take-up reel axis extracted from an industrial camera image. Because the direction of sheet material transport and the axis of the take-up reel may form an angle (lateral deviation angle) when the reel moves, an incorrect orientation can cause the waste material to wind skewed.

[0055] The current take-up point of the edge wire refers to the specific lateral position where the latest layer of edge wire contacts the take-up spool, as identified from the image. For example, if the edge wire is currently wound at the leftmost end of the take-up spool, the current take-up point can be used to determine whether to continue moving the take-up spool to the left, gradually shifting the edge wire's landing point towards the center and right side of the take-up spool.

[0056] Step S50: Determine the current winding edge features based on the winding image information to determine the current winding edge width.

[0057] The current edge winding features refer to a set of visual features that reflect the edge winding position, edge contour, lateral offset, and bonding posture of the edge winding.

[0058] The current winding edge width refers to the lateral distribution width of the waste edge wires currently wound on the winding shaft, calculated based on the characteristics of the winding edge wires. Specifically, it is calculated by extracting the pixel coordinates of the two edges of the edge wires in the winding image using an edge detection algorithm, calculating the pixel distance between the two edges, and then converting this distance using the calibration ratio to obtain the current winding edge width.

[0059] Step S51: Determine the limiting parameters of the limiting support column based on the current winding edge wire width, and control the limiting support column 45 to perform the limiting support column movement operation according to the limiting support column limiting parameters.

[0060] The limiting parameters of the limiting support columns refer to the target spacing between the two limiting support columns 45, determined based on the current width of the wound edge wire. The direction and distance of movement of the two limiting support columns 45 are determined by this target spacing. The movement of the limiting support columns 45 is achieved by the rotating mechanism 44 sliding within the moving sliding groove 431. The target spacing in the limiting parameters must be smaller than the current width of the wound edge wire, enabling the limiting support columns 45 to limit the edge wire, causing a slight tilt.

[0061] The movement operation of the limit support column refers to the action of the two rotating mechanisms 44 driving the limit support column 45 to perform lateral movement according to the limit parameters, which is used to adapt to the winding width of the edge wire.

[0062] Step S6: Determine the winding area number based on the winding image information, and determine the current winding area based on the winding area number.

[0063] The take-up area number refers to the number assigned to the effective length of the take-up spool when it is divided into several segments according to the interval, such as: left area, middle area, right area. Its function is to provide a basis for the zoning and laying of wire, so that the system can determine which segment the edge wire is currently wound on.

[0064] The current winding area refers to the winding section number of the edge wire that is currently actually wound, determined based on the current winding landing point of the edge wire in the winding image information. It is used to determine whether the winding area needs to be switched, so as to achieve uniform wire laying.

[0065] Step S60: Determine the rotation parameters of the rotating winding mechanism based on the current winding area, execute the winding mechanism movement operation according to the rotation parameters, and obtain the current number of winding rotations.

[0066] The rotation winding mechanism movement parameters refer to the horizontal movement direction and distance of the rotation winding mechanism 53 determined according to the horizontal coordinate corresponding to the current winding area number. These parameters are used to move the current winding area of ​​the winding shaft on the rotation winding mechanism 53 to a position that is aligned with the edge wire conveying position.

[0067] The current number of winding rotations refers to the cumulative number of rotations of the winding shaft from the start of the current winding cycle to the present.

[0068] Step S61: If the current number of winding rotations reaches the preset effective rotation threshold, the current winding area is re-determined based on the winding area number to determine the movement parameters of the winding mechanism, and the winding mechanism movement operation is executed according to the movement parameters of the winding mechanism, while resetting the current number of winding rotations.

[0069] The effective rotation number threshold refers to the number of rotations that the system presets to require switching the take-up area after completing a certain number of rotations.

[0070] If the current number of winding rotations reaches the effective number of rotations threshold, it means that the current section has been wound to the set number of times, and it is necessary to switch to the next winding area number to continue the winding. Therefore, the current winding area is redefined to execute step S60 to ensure that the winding is uniform and does not pile up in a concentrated manner.

[0071] This also includes a method for performing the movement operation of the limit support column, the method comprising: Step S62: When the current winding area is updated, determine the winding edge tilt angle based on the current winding edge characteristics and the current winding area.

[0072] The edge wire tilt angle refers to the angle (side deviation angle) formed between the edge wire winding edge and the center line of the winding shaft, reflecting whether the edge wire is wound at an angle. If the current winding area is updated, it means that the previous winding area has been wound to the set number of turns, and the rotating winding mechanism 53 has moved to the new winding area; at this time, the edge wire conveying direction and the position of the winding shaft in the current winding area may be offset, which can easily lead to the edge wire winding at an angle. Therefore, it is necessary to determine whether the edge wire is in a normal winding posture by determining the edge wire tilt angle.

[0073] Step S63: If the tilt angle of the winding edge does not fall within the preset reference winding angle range, determine the sliding parameters of the limit support column 45 to perform the movement operation of the limit support column, and obtain the current number of winding rotations.

[0074] The reference winding angle range refers to the system's preset range of allowable normal tilt angles; exceeding this range is considered an abnormal tilt.

[0075] The sliding parameters of the limiting support column 45 refer to the direction and distance of movement of the limiting support column 45 driven by the rotating mechanism 44 in order to correct the tilt angle of the winding edge wire.

[0076] The methods for determining the sliding parameters of the limiting support column 45 include: Step S630: Determine the winding angle deviation value based on the winding edge inclination angle and the reference winding angle range.

[0077] The winding angle deviation value refers to the difference between the winding edge wire tilt angle and the reference angle within the reference winding angle range. It is used to characterize the magnitude and direction of the edge wire tilt angle deviating from the normal winding angle.

[0078] Step S631: Determine the sliding parameters of the limit support column 45 by looking up the preset angle correction table based on the winding angle deviation value.

[0079] Angle correction table refers to a parameter comparison table determined through a large amount of experimental data on winding angle adjustment. It associates different winding angle deviation values ​​with the corresponding moving direction and moving distance of the limit support column 45. It is used to quickly look up the table to obtain the sliding parameters of the limit support column 45 based on the angle deviation.

[0080] This also includes a method for performing the rotation operation of the limit support column 45, the method comprising: Step S632: Acquire image information of the limit support column in real time.

[0081] The image information of the limiting support column refers to the image data collected in real time by the camera, which includes the surface contour of the limiting support column at 45°.

[0082] Step S633: Determine the current wear surface of the limit support column based on the image information of the limit support column.

[0083] The current wear surface of the limit support column refers to the current working surface area identified from the image of the limit support column 45, where the limit support column 45 is in actual contact with the edge wire and wear occurs.

[0084] Step S634: Determine the wear and indentation amount of the limit support column based on the current wear surface of the limit support column.

[0085] The wear and indentation of the limiting support column refers to the maximum indentation depth of the wear area relative to the normal surface, calculated by comparing the actual height of each measuring point in the wear area with the theoretical height of the unworn reference surface of the limiting support column 45, based on the three-dimensional contour data of the surface of the limiting support column 45 collected by the 3D laser contour sensor.

[0086] Step S635: When the wear and indentation of the limiting support column falls within the preset abnormal wear and indentation range, the effective wear surface of the limiting support column is determined based on the image information of the limiting support column.

[0087] The range of abnormal wear and indentation refers to the range of wear depth exceeding the standard determined by repeatedly conducting experiments to limit the edge wire with limit support columns of different wear degrees, and judging the impact of the limit support column 45 on the edge wire winding limit.

[0088] The effective wear surface of the limiting support column refers to the intact surface area of ​​the limiting support column 45 that has not suffered severe wear and can still guide the edge wire normally. Specifically, it is the outer circumferential surface of the limiting support column 45 that corresponds to the contact height between the edge wire and the limiting support column 45 and has not shown excessive wear or depression.

[0089] When the wear and indentation of the limit support column falls into the range of abnormal wear and indentation, it indicates that the current working surface of the limit support column 45 is excessively worn, which has affected the normal limit of the edge thread.

[0090] Step S636: When there is a wear surface of the effective limit support column, determine the rotation parameters of the limit support column based on the current wear surface of the limit support column and the wear surface of the effective limit support column.

[0091] The rotation parameters of the limiting support column refer to the rotation direction and rotation angle of the limiting support column 45 driven by the rotation mechanism 44 in order to switch to the effective working surface.

[0092] When there is wear on the effective limit support column, it means that the limit support column 45 still has a usable and intact working surface and can continue to work without replacement.

[0093] Step S637: Perform the rotation operation of the limit support column 45 based on the rotation parameters of the limit support column.

[0094] The rotation operation of the limit support column 45 refers to the action of the rotation mechanism 44 rotating circumferentially according to the rotation parameters, switching the effective limit support column wear surface of the limit support column 45 to the edge thread contact position.

[0095] This also includes a method for performing a lifting operation when there is no effective limit support column wear surface, the method comprising: Step S6360: When there is no effective limit support column wear surface, determine the vertical effective limit support column wear surface based on the limit support column image information.

[0096] When there is no effective wear surface on the limit support column, it means that all outer surfaces of the limit support column in the 45-degree circumference corresponding to the normal contact height of the edge wire are severely worn, and there is no intact circumferential working surface to continue to stably limit and guide the edge wire.

[0097] The wear surface of the vertical effective limiting support column refers to the intact surface area on the limiting support column 45 that is vertically distributed along the axial direction, has not suffered severe wear and indentation, and can still normally fit the guide wire. Specifically, it refers to the intact outer surface of the limiting support column 45 at other axial positions that are different from the current contact height of the wire.

[0098] Step S6361: When there is a wear surface of the vertical effective limit support column, determine the lifting parameters of the limit support column based on the height difference between the wear surface of the vertical effective limit support column and the current wear surface of the limit support column.

[0099] The lifting parameters of the limit support column refer to the lifting direction and lifting distance of the limit support column 45 determined in order to switch the wear surface of the vertical effective limit support column to the edge thread contact working position. The lifting of the limit support column 45 is achieved by the sliding of the limit worktable 42 along the limit lifting groove.

[0100] When there is a wear surface on the vertical effective limit support column, it means that the axial direction of the limit support column 45 still has an intact working surface that is not worn. By raising or lowering the limit worktable 42 to drive the limit support column 45 to rise or fall, the effective working surface can be switched without directly replacing the limit support column 45.

[0101] Step S6362: Perform the lifting operation according to the lifting parameters of the limit support column.

[0102] The lifting operation refers to the lifting or lowering displacement action of the limit worktable 42 along the length direction of the limit lifting groove according to the lifting parameters of the limit support column, so as to adjust the wear surface of the vertical effective limit support column to the working position of contacting the edge thread.

[0103] This also includes a method for performing a cleaning operation on the limit support column, the method comprising: Step S6363: Determine the suspected impurity area of ​​the edge wire based on the current winding edge wire characteristics.

[0104] Suspected impurity areas on the edge wire refer to areas identified based on the surface visual characteristics of the currently wound edge wire, where foreign matter such as debris, oil, and dust is attached to the surface of the edge wire.

[0105] Step S6364: When there is a suspected impurity area for edge wires, determine the current impurity position based on the suspected impurity area for edge wires.

[0106] The current impurity location refers to the real-time position of the suspected impurity area on the winding edge wire, along the spatial position of the edge wire conveying direction.

[0107] When there is an area where the edge wire is suspected to be impurity, it means that impurities are attached to the surface of the winding edge wire. The impurities need to be cleaned by friction with the limit support column 45 perpendicularly.

[0108] Step S6365: Obtain the position of the limiting support column, and determine the current distance based on the current impurity position and the position of the limiting support column.

[0109] The position of the limit support column refers to the position of the rotating mechanism 44 within the movable sliding groove 431.

[0110] The current distance refers to the straight-line distance from the current impurity position on the edge wire to the working surface of the limit support column 45, along the current edge wire conveying direction. The edge wire conveying direction refers to the direction in which the wound edge wire is conveyed from the slitting station to the waste winding shaft, which is captured by the camera and obtained through an edge recognition algorithm.

[0111] Step S6366: When the wear and indentation of the limiting support column falls within the preset range of no wear and indentation, obtain the current winding edge wire moving speed and the impurity coverage range, and determine the inward retraction time and return time of the limiting support column based on the current winding edge wire moving speed, the current distance and the impurity coverage range.

[0112] The range of no-wear indentation refers to the indentation depth range in which the surface of the limiting support column 45, as determined by multiple experimental data, shows no obvious wear or the degree of wear does not affect its normal limiting of the edge wire.

[0113] When the wear and indentation of the limiting support column falls within the preset range of no wear and indentation, it indicates that the current working surface of the limiting support column 45 is in good condition, with a flat surface and no significant indentation, and can form a stable and tight fit with the edge wire surface. At this time, the impurities on the edge wire surface can be cleaned by controlling the lateral movement of the limiting support column 45.

[0114] The current winding edge wire movement speed refers to the real-time travel speed of the winding edge wire along the edge wire conveying direction.

[0115] The impurity coverage area refers to the length of the suspected impurity area on the edge wire in the edge wire conveying direction, that is, the spatial range occupied by the impurity along the edge wire traveling direction. It is obtained by converting the pixel length of the suspected impurity area through an image recognition algorithm.

[0116] The retraction time of the limit support column refers to the time point at which the retraction action of the limit support column 45 needs to be initiated in advance before impurities reach the working face of the current winding edge wire moving speed and current distance.

[0117] The return time of the limit support column refers to the time point at which the limit support column 45 needs to be reset after the impurities have completely passed through the working surface of the limit support column 45, calculated by combining the current winding edge wire moving speed, the current distance, and the impurity coverage area.

[0118] Step S6367: Determine the current edge wire winding angle based on the image information of the limiting support column.

[0119] The current edge wire winding angle refers to the actual included angle between the winding edge wire and the working surface of the limit support column 45, which is identified from the image of the limit support column 45.

[0120] Step S6368: Determine the inward retraction parameters of the limit support column based on the current edge wire winding angle and the preset vertical edge wire winding angle, and generate a limit support column cleaning scheme by combining the limit support column inward retraction time and the limit support column return time, and perform the limit support column cleaning operation according to the limit support column cleaning scheme.

[0121] The vertical edge wire winding angle refers to the standard angle preset by the system to keep the winding edge wire and the 45 working surface of the limiting support column perpendicularly attached, so as to ensure sufficient friction to remove impurities from the edge wire surface.

[0122] The inward retraction parameter of the limiting support column refers to the inward retraction direction and inward displacement of the limiting support column determined based on the difference between the current edge wire winding angle and the vertical edge wire winding angle.

[0123] The limit support column decontamination scheme refers to a time-sequential control strategy that combines the limit support column retraction parameters, the limit support column retraction time, and the limit support column return time. It is used to adjust the limit support column's 45° posture when impurities pass by in order to achieve friction decontamination.

[0124] The cleaning operation of the limit support column refers to the action of adjusting the posture of the limit support column 45 according to the cleaning plan, so that the edge wires are perpendicular to the working surface of the limit support column 45, and removing surface impurities by using the relative friction generated by the edge wires. After cleaning, the column is reset to the normal working state.

[0125] This also includes a method for performing a limit support column avoidance operation when the wear and indentation of the limit support column does not fall within the range of no wear and indentation. This method includes: Step S63660: Determine the avoidance time and return time of the limit support column based on the current winding edge wire moving speed, current distance and impurity coverage area.

[0126] The avoidance time of the limit support column refers to the time point at which the avoidance action of the limit support column 45 needs to be initiated in advance before the impurity reaches the working face of the current winding edge wire, based on the current winding edge wire moving speed and current distance.

[0127] Step S63661: Determine the limit support column avoidance parameters based on the current edge wire winding angle.

[0128] The avoidance parameters of the limit support column refer to the avoidance direction and distance that the limit support column 45 moves away from the edge wire to avoid abnormal friction between the working surface of the wear limit support column 45 and the impurities on the edge wire surface, which would cause damage to the edge wire or embed impurities into the wear and depression.

[0129] Step S63662: Generate a limit support column avoidance scheme according to the limit support column avoidance parameters, the limit support column avoidance time, and the limit support column return time, and execute the limit support column avoidance operation according to the limit support column avoidance scheme.

[0130] The limit support column avoidance scheme refers to a time-sequential control strategy that combines the limit support column avoidance parameters, the limit support column avoidance time, and the limit support column return time. It is used to control the limit support column 45 to move away from the edge wire when impurities pass by, so as to avoid the worn working surface from contacting the impurities. After the impurities have completely passed by, the column is reset to the normal working position.

[0131] The limit support column avoidance operation refers to the specific actions performed by the limit support column 45 according to the avoidance plan. Specifically, at the avoidance time point, the limit support column 45 moves away from the edge wire according to the avoidance parameters to the avoidance position. After the impurity has completely passed, it returns to its normal working position along the original path at the return time point. This avoids abnormal friction between the worn working surface and the impurities on the edge wire surface, preventing damage to the edge wire or impurities embedding into the wear dent. It should be noted that when the limit support column 45 is away from the edge wire, the edge wire will not loosen and fall because the take-up shaft provides tension to the edge wire surface. Combined with the feeding speed and the take-up shaft speed, this ensures that the edge wire is always in a taut conveying state.

[0132] Here, the winding shaft speed is updated in real time based on tension. Specifically, the winding drive motor detects the reaction force transmitted by the edge wires. When the detected tension exceeds the preset tension reference range, the winding shaft speed is finely adjusted in real time. Since the lateral switching of the winding area does not change the winding diameter, there is no need to adjust the speed due to area changes. However, excessive edge wires wrapped in the winding area will cause the edge wires to stack layer by layer, and the winding diameter will become larger and larger. At this time, maintaining constant tension of the edge wires only through tension feedback, combined with the feeding speed, can ensure smooth winding. The tension reference range refers to the reasonable tension range preset for the edge wire winding of high surface quality stainless steel sheet. This range can ensure that the edge wires are always in a taut conveying state, avoiding loosening or falling or deviation, and can also prevent excessive tension from causing edge wire breakage, sheet surface damage, or winding deformation. Specifically, for high surface quality stainless steel sheets of different thicknesses, widths, and material grades, multiple sets of comparative experiments were conducted under actual production line conditions, with feeding speed and winding speed as variables. The real-time tension values ​​corresponding to the edge wires not loosening, not stacking, not breaking, and not damaging the sheet surface were recorded respectively.
