Abstract
The invention aims to provide a control system which can accurately control tension in a main tension region of a rubber calender. A tension control system for the main tension region of the rubber calender provided for solving the technical problem of the invention consists of a tension sensor, a tension amplifier, a PLC operational controller and a motor driver, and is technically characterized in that: the tension sensor detects the change of the tension on a force measurement roller; the tension sensor detects the tension and converts the tension into an electric signal; the tension amplifier receives and amplifies the electric signal into a standard signal; and the PLC operational controller outputs a regulating signal to the motor driver for regulating the speed of the motor after performing PID regulation so as to fulfill the aim of constant tension control.
Description
Technical field
The present invention relates to a kind of rubber rolling equipment control system, particularly tension control system for main tension region of rubber calender.
Technical background
In the past, the automatic adjusting (potentiometer) by pneumatic floating roller made the cord constant tension, and the size of tension force by the atmospheric pressure value decision, is adjusted potentiometer resistance and can be changed floating roller operating position.Control tension force not only complicated operation as position sensor by adjusting atmospheric pressure value by potentiometer, and control accuracy is also lower.
Modern calender gradually trends towards the high-tension design, and the high-tension calendering improves tire quality except making film better attached on the cord, for the user saves cost, creates bigger benefit.The automatic control of the cord tension force in the cord calender line between each section and realize that the calendering of permanent tension force has crucial meaning for the calendering quality.
Summary of the invention
The object of the present invention is to provide a kind of control system that can accurately control main tension region of rubber calender tension force.
The tension control system for main tension region of rubber calender that technical problem provided that patent of the present invention will solve is made up of tension pick-up, tension force amplifier, PLC arithmetic and control unit and motor driver, its technical characterictic is: detect dynamometry roller tension variation by tension pick-up, by described tension pick-up detection tension force is transformed into the signal of telecommunication, the tension force amplifier receives and is enlarged into standard signal, again after the PLC arithmetic and control unit carries out the PID adjusting, output is adjusted signal and is formed the speed of adjusting motor to motor driver, reaches the purpose of permanent tension force control.
The PLC arithmetic and control unit carries out the PID control method: set currency PV, preset value SV, ratio PK, derivative time TI, time of integration TD, output upper limit MV_HIGHT, bottoming MV_LOW, operation and enable ENABLE, output MV in PLC arithmetic and control unit program block.
As required currency PV with set tension value SV and mate, set the bound of MV according to the needs of adjustment amount, set PK, TI, TD according to the situation at scene and satisfy the requirement that different goods are set at friction speed and differential tension.MV is through the speed of processing controls motor.
It is owing to the speed difference between two motors is set up that present tension force produces, and the speed difference that control is adjusted between two motors according to tension force just can be realized stable tension control.At present, many site of deployment of motor driver bussing technique so just makes the response speed and anti-interference can the reinforcement greatly of speed, and control precision of tension is greatly improved.

The specific embodiment
As shown in Figure 1, the speed difference of drying device motor 1 and calender motor 2 makes cord 3 produce tension force, and act on the test roller on 4,4 effect lower compression tension pick-ups 5 on the described test roller at tension force, tension pick-up 5 changes into the signal of telecommunication with the variation of tension force; Tension force amplifier 6 in calender motor 2 receives the described signal of telecommunication, as shown in Figure 2, tension force amplifier 6 amplification signal simultaneously is a standard signal, carrying out PID through PLC arithmetic and control unit 7 again regulates, output is adjusted signal to the speed that the PC8 in the motor driver group becomes to adjust calender motor 2, reach the purpose that permanent tension force is controlled.
The PLC arithmetic and control unit carries out the PID control method, as shown in Figure 3, sets in PLC arithmetic and control unit program block:
Currency D400-I:PV,
Preset value D402-I:SV,
Ratio D500-I:PK,
Derivative time D501-I:TI,
The time of integration D502-I:TD,
Output upper limit D503-I:MV_HIGHT,
Bottoming D504-I:MV_LOW,
The operation enable M100B:ENABLE,
Output D600-I:MV.
Be set among the D402 setting tension force as required, currency is delivered among the D400, set between the bound D503 and D504 of MV according to the needs of adjustment amount, situation setting PK, TI, TD according to the scene satisfy the requirement of different goods in friction speed and differential tension setting, and MV is through the speed of processing controls motor.
High accuracy press production line master tensile region maximum tension can reach 20000N, and main tensile region is selected for use the import force cell to detect, show and participated in control.
