Winder is a special equipment for the textile industry. If a motor with an industrial frequency is used to drive the winding of the bobbin, the rotation speed of the motor will not be changed. As the diameter of the bobbin increases, the speed of the bobbin increases, and the bobbin is wound out. It will be loose and tight, and the ideal bobbin cannot be wound. If a general frequency converter is used, it is difficult to control the frequency converter to output the corresponding frequency according to the requirements of the linear speed of spinning, and it is not easy to reasonably protect the faults of yarn breakage and power transmission. The special winding machine frequency converter will overcome this shortcoming, can make the reasonable control according to the control mode that the user uses.

The entire winder production line system utilizes advanced control technology to integrate the Weilun MT6000 touch screen, inverter, and winder. At the same time, due to the outstanding features of the Weilun MT6000 touch screen, the user's operation is convenient and quick.

System Features:

(I) Dedicated winder inverter function

The professional winder inverter provides the following functions for the user: constant speed control, decelerated speed control, frequency swing speed control and frequency increase speed control. Three types of tension control can be selected for the user to use, and the yarn break is automatically stopped. When the PI adjusts, the pressure roller and the bobbin are in poor contact and stop.

Constant line speed control, that is, according to the diameter of the pressure roller, the frequency converter PI controls the spinning speed so that the pressure roller rotates at a constant speed to achieve a constant linear speed. The pulsed Hall sensor is mounted on the pressure roller.

Decreasing speed regulation is a control method in which the speed of the inverter gradually decreases as the cylinder diameter of the spinning drum increases, so that the linear velocity of the yarn is relatively constant. The pulsed Hall sensor is installed on the main winding motor shaft.

The swing frequency modulation is the periodical change of the main winding motor at a fixed frequency, which controls the elasticity of the yarn. The pulse Hall sensor is installed on the pressure roller.

Two frequency inverters are needed to increase the speed of frequency control. One frequency converter drives the spinning motor at a constant speed, and the other frequency converter controls the yarn feeding speed of the overfeed motor by means of the speed-increasing speed control, which can improve spinning efficiency.

Three types of tension adjustment control: tension adjustment by PI; voltage decrease tension adjustment; external control adjustment tension. Tension control is mainly used to control the tension of yarn transport. If the tension is well controlled, the elasticity of the yarn bobbin will be moderate.

During the running process, the current spinning length can be displayed cyclically, the spinning length can be set, and the current running frequency can be set. The yarn ingot produced by this product has a beautiful appearance and large winding capacity, which is suitable for loose tube type and tight tube type production.

(B) WEINVIEW touch screen function and interface

In the entire winder system, WEINVIEW MT6000 series touch screen plays an important role. WEINVIEW MT6000 series touch screen with its excellent 65536 color display and well-designed operating interface, allowing people to enjoy their beautiful vision, based on real-time display of the parameters of each inverter, but also can effectively control the inverter Action and accurately set various parameters, and then accurately control the operation of the winder.

On the main interface of WEINVIEW MT6000 touch screen, the main parameters of the current communication frequency converter are displayed in real time, and the current status of the frequency converter is displayed in real time with beautiful graphics, divided into: multi-speed indications such as shutdown, operation and failure. At the same time, the length parameters of the current frequency converter are visually and directly displayed in real time using a bar graph element.

In the other interface of WEINVIEW MT6000 touch screen, the main display set the parameters of the current inverter, and corresponding to the relevant function code, when you find a problem, you can quickly know what is the number of inverter parameters.

WEINVIEW MT6000 touch screen also has a very useful function, that is, you can use variables to set the station number of the drive. When a touch screen is connected to any number of frequency converters, it is easy to access each frequency converter simply by using a touch screen window program, and all you need to do is change the value of the variable to the number of the frequency converter you want to access. can.

The var0# in the address represents the variable of the station number. It is used in conjunction with the LW10000 of the touch screen. If LW10000=1, the above numerical input element is the setting for the frequency converter No.1; when LW10000=2 In this case, it is the setting for inverter No. 2.

Wei Lun’s MT6000 touch screen feature saves the engineer's energy and time, eliminating the need to make multiple windows because of the need to connect multiple inverters. At the same time, this type of setting will not affect the communication speed because the number of connected inverters is too high, because only one inverter actually communicates with the touch screen at the same time.

In this winder system, the user can also select the single station number display mode and the broadcast station number cycle display mode as required.

to sum up:

In the whole winder system, the operator displayed the entire operating system through the Wei Lun MT6000 touch screen control, which made the operation more convenient and simple, reduced many operational mistakes previously controlled by switches and buttons, and reduced the number of equipment maintenance. Improve the production efficiency; At the same time, it also eliminates the need for excessive display equipment, which greatly improves the cost-effectiveness of the system and establishes the competitive advantages of the same industry.
