Description

Technical Field

[0001] The invention relates to the field of steel plate stacking, and in particular to a method for adjusting steel plate stacking. Background Art

[0002] When the steel plates produced by the strip processing line are stacked, they are lifted by multiple horseshoe rollers, and then the horseshoe rollers rotate to drop the steel plates. However, due to equipment wear and other reasons, the synchronization of the horseshoe rollers is poor, resulting in different falling speeds of the steel plates. It is easy for one side of the steel plate to fall first and the other side to fall later, resulting in scratches between the steel plates and the horseshoe rollers, affecting the quality of the steel plates. Summary of the invention

[0003] The main purpose of the present invention is to provide a steel plate stacking adjustment method to solve the technical problem that the steel plates and horseshoe rollers are prone to scratching in the existing steel plate stacking method.

[0004] To achieve the above object, the present invention provides a method for adjusting a steel plate stack, comprising the following steps:

[0005] The distance between the first side horseshoe roller and the second side horseshoe roller is adjusted to the corresponding width of the steel plate, and the first side horseshoe roller and the second side horseshoe roller are symmetrically arranged with respect to the stacking length direction.

[0006] In the trajectory of the first side horseshoe roller and the second side horseshoe roller conveying the steel plate along the length, the first width position information of the steel plate and the first side horseshoe roller in the width direction and the second width position information of the steel plate and the second side horseshoe roller in the width direction are collected in real time.

[0007] The first width position information and the second width position information are compared, and the conveying speed of the horseshoe roller on the first side and the conveying speed of the horseshoe roller on the second side are adjusted so that the steel plate is centered during the conveying process.

[0008] After the steel plate reaches the target position, the first side horseshoe roller and the second side horseshoe roller rotate in the circumferential direction to put down the steel plate for stacking.

[0009] According to an embodiment of the present application, the step of real-time collecting first width position information of the steel plate and the first side horseshoe roller in the width direction, and second width position information of the steel plate and the second side horseshoe roller in the width direction comprises:

[0010] The position images of the first-side horseshoe roller, the second-side horseshoe roller and the steel plate are collected along the height direction.

[0011] The first distance between each area of ​​the tail of the horseshoe roller on each first side in the length direction in the position image and the steel plate is identified to obtain first width position information.

[0012] The second distance between each area of ​​the tail of the horseshoe roller on each second side in the length direction in the position image and the steel plate is identified to obtain second width position information.

[0013] According to an embodiment of the present application, the step of comparing the first width position information and the second width position information, adjusting the conveying speed of the horseshoe roller on the first side and the conveying speed of the horseshoe roller on the second side, so that the steel plate is centered during the conveying process includes:

[0014] Compare the first distance and the second distance at the same position of the horseshoe roller on the first side and the horseshoe roller on the second side.

[0015] The conveying speed of the horseshoe roller corresponding to the side where the larger value of the first distance and the second distance is located is adjusted to be smaller than the conveying speed of the horseshoe roller on the other side.

[0016] When the steel plate reaches a centered state, the conveying speed of the horseshoe roller on the first side is adjusted to be consistent with the conveying speed of the horseshoe roller on the second side.

[0017] According to an embodiment of the present application, in the step of adjusting the conveying speed of the horseshoe roller corresponding to the side where the larger value of the first distance and the second distance is located is smaller than the conveying speed of the horseshoe roller on the other side:

[0018] The conveying speed of the horseshoe roller on the first side and the conveying speed of the horseshoe roller on the second side are reduced, and the conveying speed reduction amplitude of the horseshoe roller corresponding to the side where the larger value of the first distance and the second distance is located is greater than the conveying speed reduction amplitude of the horseshoe roller on the other side.

[0019] According to an embodiment of the present application, at the moment when the first distance and the second distance are inconsistent in size, the position of the steel plate on the first side horseshoe roller and the second side horseshoe roller in the length direction is recorded.

[0020] According to the implementation mode of the present application, it also includes:

[0021] According to the position of the steel plate in the length direction, the conveying speed of the first side horseshoe roller and the conveying speed of the second side horseshoe roller, the corresponding position of the horseshoe roller that needs to be adjusted between the first side horseshoe roller and the second side horseshoe roller is determined.

[0022] According to the implementation mode of the present application, it also includes:

[0023] After the steel plate reaches the target position, height data of the steel plate at various locations in the length direction are collected.

[0024] The heights of part or all of the horseshoe rollers on the first side and the second side are adjusted according to the height data so that the steel plate is in a horizontal state in the height direction.

[0025] According to an embodiment of the present application, the step of adjusting the height of part or all of the horseshoe rollers in the first side and the second side so that the steel plate is in a horizontal state in the height direction includes:

[0026] The height data of the steel plate at all the corresponding positions of the horseshoe rollers on the first side and the horseshoe rollers on the second side are counted.

[0027] Adjust the height of the horseshoe rollers in the first side horseshoe roller and the second side horseshoe roller whose height data is not within the target height range so that the steel plate is in a horizontal state in the height direction.

[0028] According to an embodiment of the present application, the method for determining the target height range is:

[0029] The height data distribution range with the highest frequency among all the height data is taken as the target height range.

[0030] Or, the designed height range of the first side horseshoe roller and the designed height range of the first side horseshoe roller are used as the target height range.

[0031] According to the implementation mode of the present application, it also includes:

[0032] The horseshoe rollers of the first side and the second side whose rotation speeds in the circumferential direction are inconsistent are adjusted.

[0033] In the above-mentioned adjustment method for steel plate stacking, during the conveying process of the steel plate, the position information of the steel plate and the first side horseshoe roller and the second side horseshoe roller is collected, and based on this, the conveying speed of the first side horseshoe roller and the conveying speed of the second side horseshoe roller are adjusted, so that the steel plate is adjusted to the middle position, thereby increasing the probability of both sides of the steel plate falling at the same time during the falling process, reducing the probability of scratching between the steel plate and the horseshoe roller, and improving the quality of the steel plate.

[0041] The present invention provides a method for adjusting a steel plate stack. Figure 1 , including the following steps:

[0042] S100: Adjust the distance between the first side horseshoe roller and the second side horseshoe roller to the corresponding width of the steel plate, and the first side horseshoe roller and the second side horseshoe roller are symmetrically arranged with respect to the stacking length direction.

[0043] The plurality of horseshoe rollers are arranged in two rows and are arranged opposite to each other. One row is the first side horseshoe roller, and the other row is the second side horseshoe roller. The first side horseshoe roller and the second side horseshoe roller respectively include a plurality of horseshoe rollers, and each horseshoe roller is connected to a corresponding oil cylinder. The stacking length direction is parallel to the length direction of the first side horseshoe roller and the length direction of the second side horseshoe roller.

[0044] The distance between the first side horseshoe roller and the second side horseshoe roller can be adjusted by the corresponding oil cylinder. When the distance between the two is adjusted to be suitable for the width of the conveyed steel plate, the actual width of the two is slightly larger than the width of the steel plate. Both sides of the steel plate are at a certain distance from the edges of the first side horseshoe roller and the second side horseshoe roller.

[0045] S200: In the trajectory of the first side horseshoe roller and the second side horseshoe roller conveying the steel plate along the length, first width position information of the steel plate and the first side horseshoe roller in the width direction and second width position information of the steel plate and the second side horseshoe roller in the width direction are collected in real time.

[0046] In this step, the first width position information and the second width position information during the steel plate transmission process are collected in real time, with the purpose of collecting the distances between the two sides of the steel plate and the edges of the first side horseshoe roller and the second side horseshoe roller. For example, the above position information can be collected by image analysis or by distance sensor.

[0047] S300: Compare the first width position information and the second width position information, and adjust the conveying speed of the horseshoe roller on the first side and the conveying speed of the horseshoe roller on the second side so that the steel plate is centered during the conveying process.

[0048] In this step, the first width position information and the second width position information are compared to determine whether the steel plate is located in the middle position. If it is not in the middle position, the conveying speed of the horseshoe roller on the first side and the conveying speed of the horseshoe roller on the second side can be adjusted so that the steel plate returns to the middle position after deviating from the middle position to complete the centering.

[0049] S400: After the steel plate reaches the target position, the first side horseshoe roller and the second side horseshoe roller rotate circumferentially to put down the steel plate for stacking.

[0050] After the steel plate reaches the target position, illustratively, a limit mechanism, such as a limit plate, is set at the target position. When the steel plate touches the limit plate, it cannot continue to move forward, that is, it reaches the target position.

[0051] The first side horseshoe roller and the second side horseshoe rotate towards each other, that is, rotate downward respectively. After rotating to a certain angle, the steel plate slides off the first side horseshoe roller and the second side horseshoe. If it slides to the lifting platform, the subsequent side push device first pushes the steel plate sideways, and then pushes the steel plate backwards after the side push, so that the steel plate is pushed front and back and left and right. In this way, the steps of S100 to S400 are repeated, and then the next steel plate is transmitted.

[0052] When multiple steel plates are stacked, and the number of stacker blocks reaches the target number of blocks, the lifting platform is lowered into place, and the transverse chain moves the stacked steel plate bundles to the offline position.

[0053] In the above-mentioned adjustment method for steel plate stacking, during the conveying process of the steel plate, the position information of the steel plate and the first side horseshoe roller and the second side horseshoe roller is collected, and based on this, the conveying speed of the first side horseshoe roller and the conveying speed of the second side horseshoe roller are adjusted, so that the steel plate is adjusted to the middle position, thereby increasing the probability of both sides of the steel plate falling at the same time during the falling process, reducing the probability of scratching between the steel plate and the horseshoe roller, and improving the quality of the steel plate.

[0054] In some embodiments, see Figure 1 The step of real-time collecting the first width position information of the steel plate and the first side horseshoe roller in the width direction and the second width position information of the steel plate and the second side horseshoe roller in the width direction comprises:

[0055] The position images of the first-side horseshoe roller, the second-side horseshoe roller and the steel plate are collected along the height direction.

[0056] The first distance between each area of ​​the tail of the horseshoe roller on each first side in the length direction in the position image and the steel plate is identified to obtain first width position information.

[0057] The second distance between each area of ​​the tail of the horseshoe roller on each second side in the length direction in the position image and the steel plate is identified to obtain second width position information.

[0058] In this step, a plurality of image analysis devices may be arranged above the first side horseshoe roller and the second side horseshoe roller. The image analysis device includes an image acquisition mechanism and an image analysis mechanism. The image acquisition mechanism includes a camera and a high-speed camera, etc. Preferably, the image acquisition mechanism is arranged in the middle above the first side horseshoe roller and the second side horseshoe roller. The image is taken from a bird's-eye view to capture the positional relationship between the steel plate, the first side horseshoe roller, and the second side horseshoe on the horizontal plane.

[0059] The image analysis mechanism includes image processing analysis software, etc., which analyzes the image transmitted by the image analysis mechanism. The positional relationship between the steel plate, the first side horseshoe roller, and the second side horseshoe in the horizontal plane in the position image is identified. For example, the head of the steel plate is inclined toward one of the first side horseshoe roller and the second side horseshoe, or the steel plate is parallel to the first side horseshoe roller and the second side horseshoe, but close to one of them.

[0060] In some embodiments, the step of comparing the first width position information and the second width position information, and adjusting the conveying speed of the horseshoe roller on the first side and the conveying speed of the horseshoe roller on the second side so that the steel plate is centered during the conveying process includes:

[0061] Compare the first distance and the second distance at the same position of the horseshoe roller on the first side and the horseshoe roller on the second side.

[0062] The conveying speed of the horseshoe roller corresponding to the side where the larger value of the first distance and the second distance is located is adjusted to be smaller than the conveying speed of the horseshoe roller on the other side.

[0063] When the steel plate reaches a centered state, the conveying speed of the horseshoe roller on the first side is adjusted to be consistent with the conveying speed of the horseshoe roller on the second side.

[0064] In this embodiment, the distances between the head of the steel plate and the first-side horseshoe roller and the second-side horseshoe roller are usually compared.

[0065] Take this as an example to illustrate that the first distance and the second distance at the head of the steel plate are not equal, such as the first distance is greater than the second distance. At this time, the head of the steel plate is inclined toward the horseshoe roller on the second side. The transmission speed of the horseshoe roller on the first side can be adjusted to be greater than the transmission speed of the horseshoe roller on the second side, so that the movement speed of the part of the horseshoe roller on the first side of the steel plate is greater than the movement speed of the part of the horseshoe roller on the second side, so that the steel plate gradually moves toward the horseshoe roller on the first side, so that the first distance and the second distance are equal, and the centering is completed.

[0066] After the centering is achieved, the conveying speed of the horseshoe roller on the first side and the conveying speed of the horseshoe roller on the second side are adjusted in time to make them consistent, so that the steel plate maintains the centering state.

[0067] In some embodiments, in the step of adjusting the conveying speed of the horseshoe roller corresponding to the side where the larger value of the first distance and the second distance is located is smaller than the conveying speed of the horseshoe roller on the other side:

[0068] The conveying speed of the horseshoe roller on the first side and the conveying speed of the horseshoe roller on the second side are reduced, and the conveying speed reduction amplitude of the horseshoe roller corresponding to the side where the larger value of the first distance and the second distance is located is greater than the conveying speed reduction amplitude of the horseshoe roller on the other side.

[0069] In this embodiment, the transmission speed of the horseshoe roller on the first side and the transmission speed of the horseshoe roller on the second side are both reduced, and the transmission speed of the side with a larger value between the first distance and the second distance is reduced to a greater extent. In this way, during the adjustment of the centering, the overall movement speed of the steel plate is reduced, which makes it easier to reach the centered state and reduces the probability of excessive adjustment on one side and causing the other side to tilt.

[0070] In some embodiments, during the process of adjusting the centering, the difference in the transmission speed of the horseshoe roller on the first side and the horseshoe roller on the second side gradually decreases. This method can avoid the situation where, after the adjustment is achieved, the horseshoe roller on the faster side continues to move at a faster speed due to inertia, reducing the probability of over-adjustment of one side tilt and causing the other side tilt.

[0071] In some embodiments, when the first distance and the second distance are inconsistent in size, the position of the steel plate on the first side horseshoe roller and the second side horseshoe roller in the length direction is recorded.

[0072] This method can record the running position of the steel plate, facilitate the subsequent maintenance of the horseshoe roller, and reduce the probability of needing to adjust and align the steel plate during subsequent transmission.

[0073] In some embodiments, it also includes:

[0074] According to the position of the steel plate in the length direction, the conveying speed of the first side horseshoe roller and the conveying speed of the second side horseshoe roller, the corresponding position of the horseshoe roller that needs to be adjusted between the first side horseshoe roller and the second side horseshoe roller is determined.

[0075] In this embodiment, the conveying distance of the steel plate can be determined according to the position of the steel plate in the length direction. Combining the conveying speed of the horseshoe roller on the first side and the conveying speed of the horseshoe roller on the second side, it can be determined which horseshoe rollers of the first side and the second side have problems. Specifically, combining the moment when the steel plate does not tilt, the moment when it starts to tilt, the moment when it has tilted, etc., and combining the conveying speed of the horseshoe roller on the first side and the conveying speed of the horseshoe roller on the second side, it can be determined at which horseshoe roller the steel plate starts to tilt, and the tilt gradually increases, so that the horseshoe roller can be repaired and adjusted, reducing the probability of adjusting and centering the steel plate when the steel plate is subsequently conveyed.

[0076] In some embodiments, it also includes:

[0077] After the steel plate reaches the target position, height data of the steel plate at various locations in the length direction are collected.

[0078] The heights of part or all of the horseshoe rollers on the first side and the second side are adjusted according to the height data so that the steel plate is in a horizontal state in the height direction.

[0079] In this embodiment, the corresponding horseshoe rollers are adjusted according to the height data of the steel plate on each horseshoe roller so that the steel plate is in a horizontal state in the height direction. In this way, in the subsequent sliding process of the steel plate, it is not easy for one side of the steel plate to fall first and the other side to fall later, which will cause scratches between the steel plate and the horseshoe roller, affecting the quality of the steel plate.

[0080] In some embodiments, the step of adjusting the height of some or all of the horseshoe rollers on the first side and the second side so that the steel plate is in a horizontal state in the height direction includes:

[0081] The height data of the steel plate at all the corresponding positions of the horseshoe rollers on the first side and the horseshoe rollers on the second side are counted.

[0082] Adjust the height of the horseshoe rollers in the first side horseshoe roller and the second side horseshoe roller whose height data is not within the target height range so that the steel plate is in a horizontal state in the height direction.

[0083] In this embodiment, the height data in the target height range usually accounts for a relatively large proportion, which reduces the number of raising or lowering the horseshoe roller height, reduces the adjustment workload, and improves the stacking efficiency.

[0084] In some embodiments, the target height range is determined by:

[0085] The height data distribution range with the highest frequency among all the height data is taken as the target height range.

[0086] Or, the designed height range of the first side horseshoe roller and the designed height range of the first side horseshoe roller are used as the target height range.

[0087] In some embodiments, it also includes:

[0088] The horseshoe rollers of the first side and the second side whose rotation speeds in the circumferential direction are inconsistent are adjusted.

[0089] This method can ensure that the rotation speed of the horseshoe roller is consistent, and it is not easy for one side of the steel plate to fall first and the other side to fall later, which will cause scratches between the steel plate and the horseshoe roller, affecting the quality of the steel plate.

[0090] Exemplarily, the horseshoe roller is adjusted as follows:

[0091] Operation method: First, the on-site personnel measure the adjustment angle of the horseshoe roller that needs to be calibrated (i.e. the horseshoe roller that needs to be adjusted) according to the position of the steel plate, and inform the computer operator of the adjustment angle; then the system operator prohibits other horseshoe roller turning movements except the calibrated horseshoe roller turning in the system; finally, after entering the adjustment angle in the "Set Open Position" box, activate the positioning adjustment of the horseshoe roller angle until the material receiving position is reached. After the horseshoe roller is calibrated, the horseshoe roller is disabled, and then other horseshoe rollers are calibrated until all horseshoe rollers reach the calibration position. During the turning process, if the ideal turning angle is not reached, first return the horseshoe roller to the initial position, then adjust the turning angle and observe again, and debug multiple times until the ideal turning angle is reached. At this point, the horseshoe roller turning angle calibration work can be completed.

[0092] Note: The flip angle should not be too large during the initial debugging. Based on 30 degrees, gradually increase the flip angle until the ideal flip angle is reached.
