Owing to have employed technique scheme, the beneficial effect acquired by the present invention is:
The present invention is arranged by the various parameters of man-machine interface liquid crystal display touch screen to loom, is accurately controlled each electric elements by programmable controller PLC, considerably increases stability and the reliability of control system operation; Invention increases reversal valve, control reversal valve by main control unit and carry out commutating and select the control of latitude, thus solve existing loom can only monochromatic woven problem; Present invention also adds air bleeding valve, after caused by loom stop, main control unit controls exhaust valve operation, is discharged by endotracheal gas, prevents weft yarn to be blown disconnected, solves the problem that the broken yarn of existing loom existence is more.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the present invention is described in further detail, but the present invention is not limited to these embodiments.
As described in Figure 1, a kind of energy-saving air-jet loom electric-control system, comprise main control unit, driver element and wefting insertion control unit, described main control unit comprises programmable controller PLC and man-machine interface liquid crystal display touch screen, programmable controller PLC is Omron Programmable Logic Controller CPIE, described man-machine interface liquid crystal display touch screen is connected with programmable controller PLC by RS-232, can arrange the various parameters of loom easily, described programmable controller PLC is electrically connected with feeler plate by cable, the umber of pulse that feeler plate produces for detecting loom weft, wefting insertion whether successfully foundation is judged as loom, described man-machine interface liquid crystal display touch screen is connected with weft accumulator by RS-485, conveniently setting parameter is carried out to weft accumulator, be provided with the weft accumulator power panel for powering to weft accumulator between man-machine interface liquid crystal display touch screen and weft accumulator, weft accumulator power panel is connected with programmable controller PLC by cable, driver element comprises for loom running provides required voltage, and the power panel that uses for other parts is processed to the output signal of programmable controller PLC and for receiving external hand or fault stop signal and carrying out disturbing the terminal plate of process, described power panel is connected with threephase asynchronous by cable, A.C. contactor is provided with between power panel and threephase asynchronous, A.C. contactor controls threephase asynchronous and requires to go to work/frequency conversion according to loom, star/triangle, positive/negative turn is waited action, described power panel is also connected with brake disc, described terminal plate by cable respectively with incremental encoder, fault sensor and push-button station electrical connection, incremental encoder provides angle orientation for loom, fault sensor is for detecting loom operation troubles, as twisted limit, slitter edge, stop over, weft accumulator broken yarn etc., push-button station is provided with slow motion and rotates forward action button, slow motion reverse turn operation button, express action button and shut-down operation button, described wefting insertion control unit comprises reversal valve and air bleeding valve, power panel, terminal plate, reversal valve, air bleeding valve are all electrically connected with programmable controller PLC by cable, main control unit control reversal valve carries out commutation and selects latitude to control, after caused by loom stop, main control unit controls exhaust valve operation, endotracheal gas is discharged, prevents weft yarn from being blown disconnected.
Operation principle of the present invention is: during driving, and loom confirms to meet releasing of brake dish after all driving conditions, and control threephase asynchronous running, the angle given by incremental encoder, carries out the switching of work/frequency conversion, star/triangle, air-jet loom runs up in process, according to the angle that incremental encoder provides, main control unit carries out selecting look, then control reversal valve to open or close, select corresponding path, pass through certain angle again, yarn signal is put to weft accumulator, weft accumulator is put yarn loom and is carried out wefting insertion, after loom forwards respective angles to, by the signal that feeler plate provides, main control unit judges that whether wefting insertion is successful, unsuccessful, stop, successful then continue run, when main control unit receives stop sign, the running of loom control threephase asynchronous, control brake disc adhesive, brake, open air bleeding valve to be exhausted simultaneously, when loom stops completely, air bleeding valve stops exhaust completely, thus avoid the problem of broken yarn.
