Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of motor control, in particular to an optimized control method for YE5 motor. BACKGROUND

[0002] With the continuous development of automation production, the conveying system controlled by the motor plays an increasingly important role in modern production lines, especially in the field of bottled material transportation. The traditional conveying belt system generally adopts the method of driving the roller or belt to rotate by using the motor, thereby achieving the purpose of transporting materials. This conveying system can efficiently complete the material handling task. However, with the expansion of production scale and the improvement of production efficiency, the traditional conveying system gradually exposes some deficiencies, especially in the aspects of material conveying speed, material load and motor control.

[0003] The existing conveying system usually adopts a fixed conveying belt speed for material transportation, but this method fails to effectively consider the influence of material load changes on motor torque and conveying speed. For the case of heavy load, the motor often needs additional control to ensure the stable operation of the conveying belt, which requires the motor to adjust its torque and conveying speed in real time to adapt to different working conditions. At the same time, the existing motor control strategy is usually simple and lacks dynamic adjustment capability, which cannot be optimized and adjusted according to the real-time state of the materials on the conveying belt, resulting in energy waste and reduced production efficiency.

[0004] In addition, the traditional conveying belt system mostly adjusts the running state of the equipment through manual intervention, lacking the flexibility of automatic control. For example, when the subsequent production machine has a problem, the production speed of the production machine cannot keep up with the conveying speed of the materials, causing the conveyed materials to be excessive, resulting in material accumulation or stagnation. For this condition, the traditional system can only be dredged or adjusted by manual means, which not only increases the labor cost, but also may cause production delay due to slow response. More importantly, when material accumulation occurs in the production line, the existing conveying system fails to provide a flexible control strategy to respond to this situation in real time, resulting in damage to the overall efficiency of the production line.

[0005] Therefore, the present method proposes to flexibly adjust the motor according to the number of materials existing on the conveying system, so that the conveying system remains constant. In addition, when the subsequent production machine has a temporary problem and does not need to control the conveying system to stop, the method controls the material accumulation at a suitable position by using temporary accumulation, and automatically adjusts the accumulated material after the temporary problem is eliminated, so that the accumulated material is normally conveyed.

[0090] The torque of the YE5 motor is controlled to be equal to the current torque.

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

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

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

[0094] 2. The motor ratchet structure can control a certain roller on the main conveying belt to be separated from the driving belt when material accumulation is needed, so that the roller is no longer driven by the driving motor, the roller no longer transports materials, reduces the friction of the roller on the accumulated materials, and avoids continuous extrusion of the accumulated materials in the accumulation area, avoiding damage to the materials.

[0095] 3. By adjusting the torque of the YE5 motor and establishing a torque change model according to the quantity of bottled materials and the conveying speed, the precise control of the main conveying belt load is realized, which can effectively avoid motor overload or conveying belt blockage, improve equipment operation efficiency; the dynamic relationship between motor torque and material quantity and conveying speed can be accurately predicted to ensure smooth operation of the main conveying belt under different load conditions; through precise torque control, equipment wear and energy consumption are reduced, power utilization rate is improved, and the service life of the motor and the conveying belt system is prolonged; the optimized control method performs well in high and low load states, effectively avoiding system failures caused by sudden load increase; at the same time, the establishment of the torque change model can obtain the required motor torque when the conveying speed of the conveying belt needs to be adjusted according to the required conveying speed and the torque change model.

[0096] 4. When the quantity conveyed per unit is less than the quantity produced per unit, in order to ensure that the production machine operates at its highest efficiency, the conveyor belt speed is increased by controlling the motor speed, thereby accelerating the transport speed of materials. During this process, the torque required for the conveyor belt to reach the target conveying speed is obtained through a torque variation model. This method can precisely control the required conveying speed and ensure the stability of the conveying. At the same time, this method of increasing the conveyor belt speed can ensure that the entire production line operates at its maximum efficiency.

[0097] 5. By setting a shutdown threshold and determining whether maintenance is needed based on the difference between the unit conveying quantity and the unit production quantity, this method can identify whether a serious fault has occurred, causing the production machine's speed to be much lower than the conveyor belt's material conveying speed, resulting in a large accumulation of material on the conveyor belt. In the event of such a serious fault, the motor can be stopped in time, thereby stopping the conveyor belt from conveying material and preventing a large accumulation of material. At the same time, this method can also implement a temporary accumulation strategy for minor problems that can be quickly resolved. After the problem is resolved, normal production can continue, reducing the time spent on starting and stopping the motor.

[0098] 6. By comparing the first and second quantities, after the problem is resolved and normal material conveying begins, the side with the larger accumulated quantity is conveyed first. This method ensures that the material can continue to be conveyed more smoothly after the influencing factors are eliminated, avoiding excessive accumulation or stagnation of material on one side. By prioritizing the conveying of material on the side with the larger accumulated quantity, the production line can be balanced, avoiding jams 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, the conveying speed of the three sub-conveyors can be controlled, creating a speed difference between the three sub-conveyors. This method ensures that, after eliminating influencing factors, the accumulated material can be transported to the narrow conveyor belt at different speeds, thereby automatically separating the accumulated material and ensuring the smooth progress of subsequent production steps.

Detailed Implementation

[0107] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0108] An example of an optimized control method for a YE5 motor includes:

[0109] Reference Figure 1 Bottled materials are transported using the main conveyor belt;

[0110] The main conveyor belt is a roller conveyor belt, which consists of parallel rollers;

[0111] Reference Figure 3 The main conveyor belt uses belts to connect adjacent rollers in sequence. By connecting the rollers on the main conveyor belt in sequence using belts, only one YE5 motor is needed to drive the entire main conveyor belt. At the same time, this single-motor drive method can facilitate the control of the main conveyor belt and ensure that each roller on the main conveyor belt rotates at the same speed, thus ensuring stable material conveying.

[0112] The transport direction of the main conveyor belt is recorded as the positive direction;

[0113] Traverse each roller on the main conveyor belt in the positive direction, and mark the first roller as the first roller of the main conveyor belt.

[0114] Reference Figure 6 The first roller is connected to a YE5 motor by a belt. The YE5 motor drives the first roller to rotate, and the first roller drives each roller to rotate in turn via the belt.

[0115] Traverse each roller on the main conveyor belt in the positive direction, and record the last roller as the end roller of the main conveyor belt;

[0116] Obtain the number of rollers present on the main conveyor belt, and record it as A;

[0117] Obtain the product of 30% and A, and record the result as B;

[0118] Starting from the end roller, select each roller in the reverse direction of the positive direction in turn, and stop when the number of selected rollers equals B, and record the selected roller as the marker roller;

[0119] Use a motor ratchet structure in each marker roller to control whether the roller rotates with the belt when the YE5 motor rotates;

[0120] Referring to Figure 4 and Figure 5 , the motor ratchet structure includes a ratchet motor, a ratchet motor gear, a bearing, and a rack, and the motor in the motor ratchet structure is recorded as the ratchet motor;

[0121] When the roller needs to rotate with the belt, the ratchet motor drives the rack to engage with the rack buckle on the inner wall of the pulley;

[0122] When the roller needs to stop, the ratchet motor drives the rack to disengage from the rack buckle on the inner wall of the pulley. Through the motor ratchet structure, a certain roller on the main conveyor belt can be controlled to be separated from the driving belt when material accumulation is needed, so that the roller is no longer driven by the driving motor, the roller no longer transports materials, reduces the friction of the roller on the accumulated materials, and avoids continuous extrusion of the accumulated materials in the accumulation area, avoiding damage to the materials.

[0123] Referring to Figure 1 , three sub-conveyor belts are used at the end of the main conveyor belt, and three sub-motors are used to drive each sub-conveyor belt to rotate to transport bottled materials transported by the main conveyor belt;

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

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

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

[0127] When the production machine in the production line is working normally:

[0128] Obtain the conveying speed of the main conveying belt, denoted as normal speed;

[0129] Obtain the number of bottled materials existing on the main conveying belt at the same time, denoted as normal number;

[0130] Obtain the torque size of the current YE5 motor, denoted as normal torque;

[0131] Increase one bottled material on the conveying belt each time, and after each time of increasing bottled material, adjust the torque of the YE5 motor, change the conveying speed of the main conveying belt, and record the changed speed of the main conveying belt, the adjusted torque of the YE5 motor, and the number of increased bottled materials;

[0132] Take the number of bottled materials on the main conveying belt after each time of increasing bottled material and the changed speed of the main conveying belt each time as input, and take the adjusted torque of the YE5 motor as output, to establish a model of the change of the conveying speed of the main conveying belt with the torque of the YE5 motor under the condition that the main conveying belt carries different numbers of bottled materials, denoted as torque change model. Through the adjustment of the torque of the YE5 motor and the establishment of the torque change model according to the number of bottled materials and the conveying speed, the accurate control of the load of the main conveying belt is realized, which can effectively avoid the overload of the motor or the blocking phenomenon of the conveying belt, and improve the operation efficiency of the equipment; the dynamic relationship between the motor torque and the number of materials and the conveying speed can be accurately predicted, ensuring the smooth operation of the main conveying belt under different load conditions; through accurate torque control, equipment wear and energy consumption are reduced, power utilization is improved, and the service life of the motor and the conveying belt system is prolonged; the optimized control mode can perform well under high load and low load conditions, effectively avoiding system failures caused by sudden load increase; at the same time, the establishment of the torque change model can provide a basis for subsequent adjustment of the conveying speed of the conveying belt. When the conveying speed of the conveying belt needs to be adjusted, the torque of the motor that needs to be adjusted can be obtained by combining the required conveying speed with the torque change model.

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

[0134] Respectively control the rotating speeds of the three sub-motors to make the conveying speeds of the three sub-conveying belts consistent with the conveying speed of the main conveying belt;

[0135] Control the rotating speed of the secondary motor to make the conveying speed of the narrow strip conveying belt consistent with the conveying speed of the main conveying belt.

[0136] Take the main conveying belt, the three sub-conveying belts, and the narrow strip conveying belt as the conveying module of the production line together;

[0137] Set a unit of time;

[0138] The quantity of the bottled material transferred by the transfer module to the production machine per unit time is obtained, and is denoted as a unit transfer quantity;

[0139] The quantity of the bottled material processed by the production machine per unit time is obtained, and is denoted as a unit production quantity;

[0140] When the unit transfer quantity is less than the unit production quantity, the unit production quantity of the current production machine is obtained, and is denoted as a first production quantity;

[0141] When the unit transfer quantity of the main transfer belt is equal to the first production quantity, the transfer speed required by the main transfer belt is obtained, and is denoted as a first transfer speed;

[0142] The quantity of the bottled material existing on the current main transfer belt is obtained, and is denoted as a first quantity;

[0143] When the quantity of the bottled material carried by the main transfer belt is the first quantity, and the transfer speed of the main transfer belt is equal to the first transfer speed, the torque required by the YE5 motor is obtained through the torque change model, and is denoted as a first torque;

[0144] The torque of the YE5 motor is controlled to be equal to the first torque, so that the transfer speed of the main transfer belt is equal to the first speed;

[0145] The rotation speeds of the three sub-motors are controlled, so that the transfer speeds of the three sub-transfer belts are equal to the first speed;

[0146] The rotation speed of the secondary motor is controlled, so that the transfer speed of the narrow strip transfer belt is equal to the first speed; when the unit transfer quantity is less than the unit production quantity, in order to make the production machine run at the highest efficiency, the rotation speed of the motor is controlled to increase the conveying speed of the transfer belt and speed up the transportation speed of the material. In this process, the torque required by the conveying belt to reach the target transfer speed is obtained through the torque change model. This method can accurately control the required transfer speed and ensure the stability of the conveying. At the same time, this way of increasing the transfer speed of the transfer belt can ensure that the entire production line runs at the maximum efficiency.

[0147] When the unit transfer quantity is equal to the unit production quantity, no adjustment is made;

[0148] When the unit transfer quantity is greater than the unit production quantity, the difference between the unit transfer quantity and the unit production quantity is obtained, and is denoted as a unit difference;

[0149] The ratio of the unit difference to the unit production quantity is obtained, and is denoted as a difference ratio;

[0150] A determination threshold for determining whether the transfer module needs to be completely stopped is set, and is denoted as a stop threshold;

[0151] When the phase difference ratio is greater than or equal to the shutdown threshold, control all the motors to stop, and perform a maintenance check on the production machine;

[0152] When the phase difference ratio is less than the shutdown threshold, then obtain the influencing factor that reduces the unit production quantity of the production machine;

[0153] If the elimination time of the existing influencing factor is greater than the unit time, then control all the motors to stop, and perform a maintenance check on the production machine;

[0154] If the elimination time of the existing influencing factor is less than or equal to the unit time, then execute a temporary accumulation strategy. By setting the shutdown threshold and determining whether shutdown for maintenance is needed according to the difference between the unit conveying quantity and the unit production quantity, this method can determine whether a serious failure has occurred based on the current unit production quantity and unit conveying quantity, so that the production speed of the production machine is much less than the conveying speed of the conveying belt, causing a large amount of material to accumulate on the conveying belt. When such a serious failure occurs, the motor is controlled to stop rotating, and the conveying belt is stopped from conveying material, thereby avoiding a large amount of material accumulation. At the same time, when a temporary and quickly removable small problem occurs, the temporary accumulation strategy can be executed, and normal production can continue after the problem is resolved, which reduces the start and stop of the motor and avoids the time consumed by the start and stop of the motor.

[0155] The temporary accumulation strategy includes:

[0156] Referring to Figure 1 At the end of the main conveying belt transport direction, control the telescopic partition to rise and block the bottled material transported by the main conveying belt;

[0157] After the telescopic partition rises, monitor the movement of each bottled material on the main conveying belt;

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

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

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

[0161] Control the action of the pawl motor in each selected marking cylinder, and separate the rack teeth from the rack teeth buckle in the inner wall of the pulley, so that the selected marking cylinder does not rotate with the belt;

[0162] When the influencing factors are excluded, the distribution of the bottled materials in the stop state is obtained;

[0163] Referring to Figure 1 and Figure 2 According to the distribution of the bottled materials in the stop state, the lever control strategy is executed.

[0186] The quantity of the bottled material currently on the main conveying belt is obtained, denoted as the current quantity;

[0187] According to the current quantity and the conveying speed of the current main conveying belt, the required torque of the YE5 motor is obtained.
