Abstract
A control method of feeding weight of plastic particles based on speed regulating motor and weight feedback is characterized in that it includes a central processor (71), which is electrically connected to a motor controller (72), and the motor controller (72) drives a actuator (73) to drive a controlled object (74) to complete an operation, so that a mixing bin (4) outputs the corresponding amount of materials, and characterized in that a detection device (75) is set on the controlled object (74), and the detection device (75) is communicated with the central processor (71).

A control method of feeding weight of plastic particles based on speed regulating motor and weight feedback,
- characterized in that it includes a central processor (71), which is electrically connected to a motor controller (72), and the motor controller (72) drives an actuator (73) to drive a controlled object (74) to complete an operation, so that a mixing bin (4) outputs the corresponding amount of materials, and
- characterized in that a detection device (75) is set on the controlled object (74), and the detection device (75) is communicated with the central processor (71).
A method for operating a plant for mixing material, the plant including a material supply (1), a conveyor system (2, 74), a weighing system (3, 75), a central processor unit (5) with a data storage and a computer unit, the data storage especially for the recording of a target weight, a first advance value and a second advance value, the computer unit especially for performing differentiation and value comparison, the method comprising the following steps:
- a) weighing an output of the conveying device (2),
- b) forming a difference between the target weight and the actual weight received from step a),
- c) comparing the difference value with the first advance value,
- d) operating the conveyor system (2) at a first speed if the difference value of step c) exceeds the first advance value, or
- e) operating the conveyor system (2) at a second speed if the difference value of step c) falls below the first advance value and exceeds the second advance value, and
- f) stopping the conveyor system (2) if the difference value of step c) falls below the second advance value.
