Description

Technical Field

[0001] The present invention relates to the technical field of motor control, and in particular to an optimization control method for a YE5 motor. Background Art

[0002] With the continuous development of automated production, conveying systems controlled by motors play an increasingly important role in modern production lines, especially in the field of bottled material transportation. Traditional conveyor belt systems generally use motors to drive rollers or belts to rotate to achieve the purpose of transporting materials. This conveying system can efficiently complete the task of material handling. However, with the expansion of production scale and the improvement of production efficiency, traditional conveying systems have gradually exposed some shortcomings, especially in terms of material transmission speed, material load and motor control.

[0003] Existing conveying systems usually use a fixed conveyor belt speed to transport materials, but this method fails to effectively consider the impact of changes in material load on motor torque and transmission speed. For heavier loads, the motor often requires additional control to ensure stable operation of the conveyor belt, which requires the motor to be able to adjust its torque and transmission speed in real time to adapt to different working conditions. At the same time, existing motor control strategies are usually simple and lack dynamic adjustment capabilities. They cannot be optimized and adjusted according to the real-time status of the material on the conveyor belt, resulting in energy waste and reduced production efficiency.

[0004] In addition, traditional conveyor belt systems mostly adjust the operating status of the equipment through manual intervention, and lack the flexibility of automated control. For example, if problems occur in subsequent production machines, the production speed of the production machines cannot keep up with the material transmission speed, resulting in excessive materials being transported, resulting in material backlog or stagnation. For this situation, traditional systems can only be cleared or adjusted by manual means, which not only increases labor costs, but may also cause production delays due to slow response. More importantly, when material backlogs occur in the production line, the existing conveying system fails to provide a sufficiently flexible control strategy to respond to this situation in real time, resulting in the overall efficiency of the production line being impaired.

[0005] To this end, this method proposes a method of flexibly adjusting the motor according to the amount of material on the conveying system to keep the conveying system constant. In addition, when temporary problems occur in subsequent production machines and there is no need to control the conveying system to stop, a temporary accumulation method is used to control the accumulation of materials in appropriate locations, and after the temporary problems are eliminated, the accumulated materials are automatically adjusted so that the accumulated materials can be transported normally. Summary of the invention

[0091] The telescopic partition is controlled to descend so that the bottled materials can be transported to the production machine.

[0092] The present invention has the following beneficial effects:

[0093] 1. The rollers on the main conveyor belt are connected in sequence through belts. This method can use only one YE5 motor to drive the entire main conveyor belt. At the same time, this single-motor driving method can facilitate the control of the main conveyor belt and make each roller on the main conveyor belt rotate at the same speed to ensure stable material transportation.

[0094] 2. Through the motor tooth structure, a roller on the main conveyor belt can be controlled to separate from the drive belt when materials need to be accumulated, so that the roller is no longer driven by the drive motor and no longer transports materials, reducing the friction of the roller on the accumulated materials and avoiding continuous squeezing of the accumulated materials in the accumulation area to avoid damage to the materials.

[0095] 3. By adjusting the torque of the YE5 motor and establishing a torque change model based on the number of bottled materials and the conveying speed, the load of the main conveyor belt can be accurately controlled, which can effectively avoid motor overload or conveyor belt blockage and improve equipment operation efficiency; the dynamic relationship between the motor torque, the number of materials and the conveying speed can be accurately predicted to ensure the smooth operation of the main conveyor belt under different load conditions; through precise torque control, equipment wear and energy consumption are reduced, power utilization is improved, and the service life of the motor and conveyor belt system is extended; the optimized control method can perform well under high load and low load conditions, effectively avoiding system failures caused by sudden load increases; at the same time, the establishment of the torque change model allows the torque of the motor to be adjusted according to the required transmission speed combined with the torque change model when the conveying speed of the conveyor belt needs to be adjusted later.

[0096] 4. When the unit transmission quantity is less than the unit production quantity, in order to make the production machine run at the highest efficiency, the speed of the motor is controlled to increase the conveying speed of the conveyor belt and speed up the transportation of materials. In this process, the torque required for the conveyor belt to reach the target transmission speed is obtained through the torque change model. This method can accurately control the required transmission speed and ensure the stability of the transmission. At the same time, this method of increasing the conveyor belt transmission speed can ensure that the entire production line runs at the highest efficiency.

[0097] 5. By setting the shutdown threshold and judging whether it is necessary to shut down for maintenance and inspection based on the difference between the unit transmission quantity and the unit production quantity, this method can judge whether a serious fault occurs based on the current unit production quantity and unit transmission quantity, making the production speed of the production machine much lower than the speed of the conveyor belt conveying materials, resulting in a large amount of material accumulation on the conveyor belt. When such a serious fault occurs, the motor is promptly controlled to stop, and the conveyor belt stops conveying materials to avoid a large amount of material accumulation. At the same time, this method can execute a temporary accumulation strategy when a small problem that can be quickly eliminated occurs, and continue normal production after the problem is eliminated, which can reduce the start and stop of the motor and avoid the time spent on starting and stopping the motor.

[0098] 6. By comparing the first quantity and the second quantity, after the problem is eliminated, when normal material transportation begins, the side with a larger accumulated quantity will be transported out first. This method can ensure that after the influencing factors are eliminated, the material can continue to be transported more smoothly, avoiding excessive backlog or retention of materials on one side; by giving priority to transporting the side with a larger accumulated quantity, the balance of the production line can be achieved, avoiding stagnation or congestion caused by excessive material accumulation, and improving the efficiency and stability of the entire production process.

[0099] 7. By controlling the rotation speed of the three sub-motors, and then controlling the conveying speed of the three sub-conveyor belts, there is a speed difference among the three sub-conveyor belts. In this way, after eliminating the influencing factors, it can be ensured that the accumulated materials can be transported to the narrow conveyor belt at different speeds, and then the accumulated materials can be automatically separated, ensuring the smooth progress of subsequent production steps.

[0124] At the end of the conveying direction of the three sub-conveyor belts, a narrow conveyor belt is used, and the narrow conveyor belt is driven to rotate by a secondary motor to transport the bottled materials transported by the sub-conveyor belts to the production machine for production;

[0125] The three sub-conveyor belts are belt-type conveyor belts, connected to the ends of the main conveyor belt, and are in the same plane as the main conveyor belt;

[0126] The narrow conveyor belt is a belt conveyor belt, which is connected to the ends of the three sub-conveyor belts in the conveying direction and is located in the same plane as the three sub-conveyor belts.

[0132] The number of bottled materials on the main conveyor belt after each increase of bottled materials and the speed of the main conveyor belt changed each time are taken as input, and the adjusted torque of the YE5 motor is taken as output. A model of the change of the transmission speed of the main conveyor belt with the torque of the YE5 motor is established when the main conveyor belt carries different numbers of bottled materials, which is recorded as the torque change model.

[0133] When the production machines in the production line are operating normally:

[0154] If the elimination time of the existing influencing factors is less than or equal to the unit time, the temporary accumulation strategy is executed. By setting the shutdown threshold and judging whether it is necessary to shut down for maintenance and inspection based on the difference between the unit transmission quantity and the unit production quantity, this method can judge whether there is a serious fault based on the current unit production quantity and unit transmission quantity, making the production speed of the production machine much lower than the speed of the conveyor belt conveying materials, resulting in a large amount of material accumulation on the conveyor belt. When such a serious fault occurs, the motor is controlled to stop in time, and then the conveyor belt stops conveying materials to avoid a large amount of material accumulation; at the same time, this method can execute a temporary accumulation strategy when a small problem that can be quickly eliminated temporarily occurs, and continue normal production after the problem is eliminated, which can reduce the start and stop of the motor and avoid the time spent on the start and stop of the motor.

[0155] The temporary accumulation strategy includes:

[0156] Reference Figure 1 , at the end of the main conveyor belt in the transport direction, the telescopic partition is controlled to rise to block the bottled materials transported by the main conveyor belt;

[0157] When the telescopic partition is raised, the movement of each bottled material on the main conveyor is monitored;

[0158] When the position of a bottled material moves along the transport direction of the main conveyor belt, and the moving direction is consistent with the transport direction of the main conveyor belt, the state of the bottled material is recorded as the transport state;

[0159] When a bottled material position does not move in the transport direction of the main conveyor, the state of the bottled material is recorded as a stopped state;

[0160] Whenever a bottled material changes from a transport state to a stop state, the coverage area of ​​all bottled materials currently in the stop state on the main conveyor belt is obtained, and the marking roller covered by the coverage area is obtained, which is recorded as the selected marking roller;
