Keywords]: Siemens and the China Textile Machinery Company in a well-known large-scale joint Cooperation Successfully developed K3502 Carpet Continuous Twisted laying machine. K3502 Carpet Continuous Twisted laying machine spindle number 120; ingots from 500mm; total length of the whole machine 37m. Control system uses a machine to regulate both sides of completely independent way.

China is really a country with hand-woven wool and silk carpets in the united kingdom. Until Honeywell (former BASF) settled in Shanghai, before checking out make use of the BCF carpet weaving. With more and much more offices and hotels, new carpet yarn plant expected. Guarana initially produced low-quality tufted carpet yarn heat setting is actually producing, and holds 30% share of the market. Tufted rug from China consumed 2.7 million m2 in 2002 growing to.8 million in 2004 m2. Expected annual rate of growth of the next decade 10%. Now, the twisting heat setting products are the cause of 80% with the U.S. market, accounting for 55% Europe 60%, but Other Local business of only 35%. Has never yet been a lot of countries while using technology of this type will probably have high-speed development.nt.

Siemens and domestic enterprises together in a well-known large-scale textile machinery cooperate successfully developed K3502 Carpet Continuous Twisted laying machine. K3502 Carpet Continuous Twisted laying machine spindle number 120; ingots from 500mm; total entire whole machine 37m. Control system relies on a machine to regulate each party of completely independent way. Left and right points are similar two completely independent control system.

Control technique is split into head and the entire body electrical switch box spindle control two parts. These include an exhibit setting unit and also the all over the place system speed controller plus the nearly everywhere spindle controller.

1. Display setting unit: Siemens TP270-10 color touch screen, is responsible for setting parameters to overpower orders issued along with the display of machine status work. Screen display operating at around two parts, everywhere you look side from the machine setting and display of process parameters and operating status.

The principle menu includes this:

Process parameters: parameters setting and management. Should set your passwords.

Parameters formula: the formula of various process parameters, an easy task to manage, need password.

2. Speed controller system: Siemens S7-226 PLC Liable for the control; process parameters from the transmission and management; machine operation and run coordination; machine state data management; machine the fault information processing. Control block diagram is as follows.

S7-226 PLC With CANopen bus (self communications card) basis, with the spindle around the spindle control card microcontroller attached to the finishing the spindle control, data acquisition.

3. Spindle speed control: Siemens MM44075KW by 2 units Inverter 60 sets of right and left side were driven spindle Motor . System controller settings as well as the spindle in line with the actual average speed of communication by making use of control after operation Inverter Operation. Control accuracy 0.01HZ.

4. Winding speed control: Siemens MM4400.75KW by 2 units converter 2 teams of left and right side respectively, winding drive slow Motor . Winding inverter rotary encoder with integral supporting closed-loop system feedback system; control accuracy 0.01HZ.

5. Over-feed speed control: the two teams of Siemens MM4404KW converter 2 sets of nearly everywhere sides were driven overfeed gear motor. Over-feed inverter rotary encoder with integral supporting closed loop feedback system; control accuracy 0.01HZ.

6. Traverse speed control: by 2 units Panasonic 750W AC servo drives and drive motor plus reducer were moving left and right side on the yarn traverse, traverse winding, and speed to cross within the set angle, anti-folding length 1 and cross-angle cross angle between 2 cycle by 0.5  step increase, decrease run.

7. Spindle control: the spindle because of the respective MCU.

1 spindle start, stop: the traditional individual through the spindle stop. Mainly for electric spindle running, brake, break yarn signal to gauge, namely, long and light-weight within the interlock control signal. Be covered tube through the stop.

Off yarn and decrease in Zhang monitoring: generated at the same time off from the twisting yarn or yarn tension fluctuation, the spindle stops can order the suitable spindle required parking plus the issue of fault signal.

Each spindle with five sorts of state, normal operation, normal stop, break yarn, stall, full control.

Through the actual operation proves: Siemens MM440 Inverter and S7-200PLC, performance and quality is stable and reliable, and convenient, fast.
