Motor drive belt, conveyor belt of the item in the stipulated time arrived at the specified location, can't come early, also not late, the error is within 2 seconds, the conveyor belt loop movement, how to reduce the motor as possible in the process of running the accumulative error

CodePudding user response:

Add two switch, volume detected items one, and then put a specified location, once detected according to the distance from a given speed in the past, the error of a seconds without problem, and there is no accumulated error

CodePudding user response:

Multi-purpose a few sensors or motor with high precision

CodePudding user response:

Use travel switch control motors

CodePudding user response:

Error 2 seconds, using basic stepper motor can solve, do not need to add sensors,
Or to servo motor position control,
Some general closed-loop system than the open loop system of high precision,
No detail, controller and motor can only think of these,

CodePudding user response:

Encoders can be used to determine the conveyor belt movement distance

CodePudding user response:

Using servo belt (tooth), steady speed control motor to control, can only use the time after

CodePudding user response:

Test the speed of belt, no matter how the motor speed change, make the belt control within a certain speed can control the time of arrival of the goods,

CodePudding user response:

You should be a open loop system, make the closed-loop system

CodePudding user response:

Must have feedback, non-stop adjustment

CodePudding user response:

Servo motor is very important

CodePudding user response:

2 seconds, tolerance is very big, this is very good, but need to buy a few more objects detection sensor, the simplest such as switch, switch between, of course, is as close as possible in theory, it can more accurately estimate the distance of the object, and then control the motor speed, complex solution is placed in the target position distance sensor, fast measuring objects close to the distance, and then control the speed, as it is relatively complex, but the precision is high,

CodePudding user response:

PID, ensure stability

CodePudding user response:

Given good distance, speed control, and then with the actual location and the location of the preset speed differential feedback compensation instructions

CodePudding user response:

Low cost of motor with encoder, cost permitting, you can use the ac frequency converter drive motor, using stepper motor or servo motor...

CodePudding user response:

Encoder to add electric eye, the initial position of the electric signal set encoder, adjust the speed according to the return value of the encoder,

CodePudding user response:

Weight, load transmission speed and distance, the scope of these factors can determine the choice of motor, or of what the actual use of motor

If the load is very light and high speed requirements (short distance) is the preferred stepper motor, the rotation time is fixed, and then according to the distance to calculate the pulse number and speed of motor...

Other motor only add position feedback to control...

Depends on the feedback control error, the closed-loop...
