Description

Technical Field

[0001] This utility model belongs to the field of strip steel production technology, specifically relating to a waste edge collection machine and an adaptive control system. Background Technology

[0002] In cold-rolled strip steel production lines, the recycling of waste edges generated during strip edge shearing has always been a crucial production step. As raw materials for downstream manufacturers, the tearing effect of waste edge clumps on the shearing quality of cold-rolled strip during waste edge collection necessitates the stable and reliable operation of the waste edge collector to reduce the pulling force on the waste edges and prevent edge breakage. At the same time, it is also necessary to prevent the waste edge clumps from collapsing due to insufficient pulling force. The commonly used control method on site is to use a drive motor for tension limiting and speed control. However, due to the irregularity of waste edge collection and the increased accumulated weight of the clumps, the motor needs to provide greater torque to maintain stable pulling force on the waste edges, making it difficult for the waste edge collector to operate stably and reliably. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings of the prior art and provide a waste edge collector and an adaptive control system. By setting an industrial camera to capture the waste edge tufting process of the waste edge collector, the tensile force of the waste edge and the accumulation of the waste edge tufts are adjusted in real time to achieve stable operation of the waste edge collector.

[0004] The technical solution of this utility model is: a waste edge collection machine, including a frame, a swing device for driving the frame to move left and right, and a clamping mechanism for winding waste edge. The clamping mechanism is mounted on the frame and includes a driven clamping plate and a driving clamping plate. A transmission device is connected to the outside of the driving clamping plate. During operation, when the moving truncated cone shaft on the inner surface of the driving clamping plate is displaced to align with the fixed truncated cone shaft on the inner surface of the driven clamping plate, the fixed truncated cone shaft and the moving truncated cone shaft form a complete rotating shaft. The swing device includes a hydraulic servo cylinder. The machine also includes a collector, a controller, and a driver. The collector includes a side industrial camera corresponding to the waste edge wire to be wound and a front industrial camera corresponding to the rotating shaft. The input end of the controller is connected to the collector, and the output end of the controller is connected to the driver and the hydraulic servo cylinder. The driver includes a frequency converter. The transmission device includes a frequency converter motor. The frequency converter is connected to the frequency converter motor.

[0005] The front industrial camera performs regional projection analysis on the real-time image of the waste edge clump to determine the height difference of the waste edge clump, and outputs a corresponding waste edge collector offset control command to the controller based on the height position of the waste edge clump. The controller performs internal logic judgment based on the received waste edge collector offset control command and outputs a control signal to the hydraulic servo cylinder. The side industrial camera performs threshold analysis on the real-time image of the drooping amplitude of the waste edge to determine the tightness of the waste edge yarn to be wound and outputs a tightness signal. The controller performs internal algorithm calculation based on the received tightness signal and outputs speed adjustment and force increase signals to the frequency converter.

[0006] The rotating shaft of the clamping mechanism is a rotating structure that gradually widens from the middle to both ends.

[0007] A waste edge collection machine includes a frame, a swinging device for moving the frame left and right, and a clamping mechanism for winding waste edges. The clamping mechanism is mounted on the frame and includes a driven clamping plate and a driving clamping plate. A transmission device is connected to the outside of the driving clamping plate. During operation, when the moving truncated cone shaft on the inner surface of the driving clamping plate is displaced to align with the fixed truncated cone shaft on the inner surface of the driven clamping plate, the fixed truncated cone shaft and the moving truncated cone shaft form a complete rotating shaft. The swinging device includes a hydraulic servo cylinder.

[0008] It also includes a side industrial camera corresponding to the waste edge wire to be wound and a front industrial camera corresponding to the rotating shaft. The transmission device includes a variable frequency motor; the variable frequency drive is connected to the variable frequency motor; the front industrial camera performs regional projection analysis on the real-time image of the waste edge clump to determine the height difference of the waste edge clump, and outputs the corresponding waste edge collector offset control command according to the height position of the waste edge clump; the side industrial camera performs threshold analysis on the real-time image of the drooping amplitude of the waste edge to determine the tightness of the waste edge wire to be wound and outputs the tightness signal.

[0009] This invention provides an adaptive control system for a waste edge collector, including a data collector, a controller, and a driver. The data collector is used to collect real-time image information of the waste edge collector and perform image analysis and judgment. The controller performs corresponding logical operations based on the control information sent by the data collector, and controls the driver to adjust the running speed and torque. The driver controls the transmission device to work according to the given speed and torque. The swing device executes the control signals sent by the controller to move laterally and stop, thereby realizing the stable operation of the waste edge collector.

[0010] The collector is used to collect images in real time of the tightness of the waste edge, the frontal area of ​​the waste edge winding in the waste edge collector, and the various areas of the waste edge clump in the waste edge collector.

[0011] Similarly, the image acquisition device also pre-captures images of the waste edge state when the waste edge collector is in normal working condition.

[0012] The processor performs threshold judgment based on the waste edge tension image collected by the collector and the pre-collected waste edge normal state image. At the same time, based on the image of the waste edge winding front view area of ​​the waste edge collector, it outputs a signal to the controller to increase or decrease the tension.

[0013] Furthermore, the image processor performs shadow brightness threshold judgment based on the image of the waste edge tangled area of ​​the waste edge collector, and outputs the positions of the high and low areas of the tangled waste edge of the waste edge collector.

[0014] The controller includes signals for receiving the increase or decrease of tension from the collector, receiving position information of the high and low areas of the waste edge collection area sent by the collector, and also receiving real-time control status signals from the driver. Based on the received signals, it performs logical judgment and processing, and outputs the final control result to the driver and the swing device.

[0015] Furthermore, the driver controls the drive unit to adjust the tension and speed according to the control command, so as to make the waste edge collection process of the waste edge collector more stable and without fluctuations, and avoid the problems of broken or loose edges.

[0016] Furthermore, the swinging device controls the swinging and pausing of the waste edge collector according to control commands, controlling the winding and collection of waste edges. At the low point of waste edge collection, the swinging device pauses to collect more waste edges for filling. At the same time, after reaching the limit position, it swings in the opposite direction to ensure that the collected waste edges are more neat.

[0017] This invention can improve the working efficiency of waste edge collection machines and enhance the economic benefits of waste edge recycling and reuse. Attached Figure Description

The industrial camera sends the command to the controller based on the tightness of the waste edge. The controller performs internal logic judgment based on the received waste edge machine offset control command and outputs analog control signals to the hydraulic servo cylinder 7.
