Turn, achievees the purpose that adjust fiber tension.
In order to solve the above problem, the specific technical solution of the utility model is as follows：A kind of fiber winding unwinding tension control
System, cylinder side are connected with swing rod, there is angle between swing rod and cylinder, and cylinder upper end is drawn to be connected with servo motor, swing rod end
It is set on face there are two crossing yarn idler wheel, crosses between yarn idler wheels for two and be equipped with encoder, encoder connect with swing rod, the output of encoder
End is connect with the high-speed counter port of PLC, the high-speed pulse output port of PLC and the input port of motor servo driver
Connection, the output port of motor servo driver and the input port of servo motor connect, and encoder port is driven with servo motor
The input port connection of dynamic device.Each material volume need to be equipped with a motor servo driver and a servo motor, be driven by swing rod
Encoder rotates, and signal is fed back to PLC by encoder, and by the pid control algorithm inside PLC calculate output given speed and
Direction of rotation, and then realize constant tensile control.It only needs to can determine whether that current tensile is more than or small by swing rod position in this system
Servo motor is adjusted in desired value, control principle is simple, and debugging is convenient.Simultaneously because every set control system control mode is identical,
Therefore only need to carry out address offset in a program when increasing unreeling shaft or increase PLC, greatly reduce programming time and programming
Difficulty, while increasing the autgmentability of this control system.

Motor driver.
Specific implementation mode
As shown in Figure 1 to Figure 3, a kind of fiber winds unwinding tension control system, and 3 side of cylinder is connected with swing rod 4, swing rod
There are angle, angle of the yarn axis 5 between swing rod 4 and cylinder 3,3 upper end of cylinder to be connected with servo motor between 4 and cylinder 3
1, it sets on 4 end face of swing rod there are two crossing yarn idler wheel 2, crosses between yarn idler wheel 2 for two and be equipped with encoder 6, encoder 6 connects with swing rod 4
It connects, the output end of encoder 6 and the high-speed counter port of PLC7 connect, high-speed pulse output port and the servo electricity of PLC7
The input port of machine driver 8 connects, and the output port of motor servo driver 8 is connect with the input port of servo motor 1, compiles
6 port of code device is connect with the input port of motor servo driver 8.
Between the PLC7 and encoder 6, between PLC7 and motor servo driver 8, encoder 6 and servo motor drive
Between dynamic device 8 connected by control line.
The motor servo driver 8 is connect with 1 power port of servo motor by power cable.
The swing rod 4 is flexibly connected with cylinder 3.
Fiber roll rotation is driven by servo motor 1, fiber crosses yarn idler wheel 2 by two of swing rod 4 makes fiber outlet side
Cylinder 3 is drawn to being parallel to, makes fiber by the power for being similar to 3 pulling force of cylinder, and swing rod 4 can be because of the pulling force and cylinder of wrapping machine
The effect of 3 pulling force and swing, can judge whether the tension that fiber receives is required tension by the angle of swing rod 4, work as pendulum
Pulling force when bar 4 is perpendicular to drawing cylinder 3 suffered by fiber is constant pulling force, only need to adjust pressure when swing rod 4 is vertical at this time
Pressure of the controller to needs.Swing rod 4 drives encoder 6 to rotate, and can judge real-time fibre by 4 swing angle of swing rod
It ties up the tension being subject to be more than, less than or equal to the tension of needs, servo motor 1 is adjusted with this and accelerates, slow down or inverts, reaches tune
Save the purpose of fiber tension.Meanwhile swing rod 4 can be caused not stress when breaking in winding process, it is accommodated in limit, this
When control system can determine whether that fiber breaks according to various conditions, and signal is sent out to wrapping machine, so that wrapping machine is stopped winding concurrent
Go out alarm, operative employee is reminded to break.
For PLC7 to the startup of 1 driver of servo motor, stopping, rotary speed, direction of rotation signal, encoder 6 is anti-to PLC7
Swing rod position signal is presented, PLC7 judges swing rod position by the signal that encoder 6 is fed back to, is calculated by PLC7 internal processes,
1 driver direction of rotation of output signal control servomotor and rotary speed drive material volume to be unreeled by servo motor 1.
Power can lead to swing rod forward when excessive, and swing rod drives encoder 6 to rotate, and PLC7 detects that 6 numerical value of encoder increases, and control is watched
It takes motor 1 to carry out accelerating to unreel, tension is made to become smaller, until judge tension at this time for the tension of needs when swing rod is vertical；When
Tension can lead to tension backward when too small, and swing rod drives encoder 6 to rotate, and PLC7 detects that 6 numerical value of encoder reduces, and control is watched
It takes motor 1 and slow down and unreel or reversely wind, so that tension is increased, wait for that swing rod 4 is rectilinear and judge that tension at this time is needs
Tension.The tension approximation that fiber is subject to can be made to be constantly equal to required tension in this manner.
Above-described is only the preferred embodiment of the utility model.It should be pointed out that for the ordinary skill people of this field
For member, without departing from the principle of this utility model, several variations and modifications can also be made, also should be regarded as belonging to this
The protection domain of utility model.
