Description

Rapier loom control system capable of improving working efficiency

Technical Field

The utility model relates to a control system of textile machinery, in particular to a control system of a rapier loom, which can improve the working efficiency.

Background

The shuttleless looms in China have been developed for nearly 20 years, and various looms are introduced through technologies, so that the learning and absorption reach the current autonomous technology research and development stage. Among them, the rapier loom is developed rapidly and applied most widely due to its advantages of high efficiency, strong variety adaptability and high automation. Towel rapier looms have also replaced the old weaving equipment as the main equipment for towel weaving. The novel rapier towel loom replaces a mechanical transmission function through an advanced electronic technology, and the controllability of a plurality of actuating mechanisms is realized. The development focuses on further improvement of stability, reliability and anti-interference capability. The prior towel rapier loom has the following problems: the low-end PLC has low running speed, low yield and low benefit and cannot meet the high-speed running requirement of the rapier loom; high-end PLC systems are high in speed but expensive in price, expensive to maintain and relatively poor in control accuracy. In addition, the control system continuously works for 24 hours in a high-noise and high-humidity environment of a loom workshop, and the existing control system cannot well meet the requirements of interference resistance, high reliability, stability, high benefit and high quality. The problems of high failure rate of a control system, difficult fault finding and long maintenance time exist. The utility model discloses a chinese patent grant publication No. CN205620780U, grant publication date 2016, 10, 5, entitled "a master control PLC-based rapier towel loom control system", is an improved system. The master control rapier towel loom control system based on the PLC comprises a master control board, wherein the master control board receives information of the switching value output unit and controls an electronic multi-arm, an electronic weft selector, an electronic selvage device, a motor contactor, a clutch high-low voltage and four-color alarm lamp; the switching value output unit also controls a curling servo, a ground warp servo, a pile warp servo and a fluffing servo; the switching value input unit receives signals of a button switch, a broken warp detection device, weft signals, an oil pressure detection switch, a shaft encoder, weft accumulator broken yarn signals, a beating-proof switch and a jacquard interface; the frequency converter is controlled by the analog output unit and the switching value output unit at the same time, and changes the rotating speed of the main motor; the analog quantity output unit transmits a sensitivity given signal to the weft yarn detector, and the weft yarn detector transmits detection data to the analog quantity input unit; the hair warp tension sensor and the ground warp tension sensor transmit data to an analog input unit built in the PLC through an analog input unit built in the PLC or a signal conditioning module. Such control systems have data storage low; the PLC has high cost and slow response speed compared with electronic control; the main control board integrates the functions of all actuating mechanisms of the loom, and once the problems in the fault board are cleared, the troubleshooting time is relatively long; the monitoring data is less, and the state of the weaving machine cannot be completely monitored; data operation cannot be performed through the USB flash disk; the flexibility of the system is not enough, the density of the wool in each weft can not be adjusted, and the weaving capacity of the double-sided wool is not enough.

The commutation sequence of the circuit comprises the following steps:

first, in phase 1: when the L1 needs to be powered on, the turn-on signal from the IGBT driving circuit enables the Q1 and the Q2 to be in a conducting state, the Q3 and the Q4 are in a closing state, the current from the power supply + passes through the Q1, the windings L1 and the Q2 to return to the power supply-, the conducting action of the L1 is completed, and the electric energy is output to the coil L1 from the power supply; when L1 needs to be powered down: the turn-off signal from the IGBT drive circuit turns Q1, Q2 off, and Q3, Q4 off, the current from L1 cannot jump, the current is connected from the power supply cathode to D1, through L1, through D2, back to the power supply anode, and the power is returned to the power supply.

Second, in phase 2: when the L2 needs to be powered on, the turn-on signal from the IGBT driving circuit enables the Q3 and the Q2 to be in a conducting state, the Q1 and the Q4 are in a closing state, the current from the power supply + passes through the Q3, the windings L2 and the Q2 to return to the power supply-, the conducting action of the L2 is completed, and the electric energy is output to the coil L2 from the power supply; when L2 needs to be powered down: the turn-off signal from the IGBT drive circuit turns Q3, Q2 off, and Q1, Q4 off, the current from L2 cannot jump, the current is connected from the power supply cathode to D3, through L2, through D2, back to the power supply anode, and the power is returned to the power supply.

Finally, in phase 3, when 3 needs to be powered on, the turn-on signal from the IGBT driving circuit makes Q3, Q4 in the on state, and Q1, Q2 in the off state, the current from the power supply + passes through Q3, windings L2, Q4, returns to the power supply-, completes the action of L3 conduction, and the electric energy is output to coil L3 from the power supply; when the power of the L3 needs to be cut off, the close signal from the IGBT driving circuit enables the Q3 and the Q4 to be in the close state, the Q1 and the Q2 are in the close state, the current from the L3 cannot suddenly change, the current is connected to the D3 from the negative pole of the power supply, passes through the L2 and the D4 and returns to the positive pole of the power supply, and the electric energy returns to the power supply.

Three voltages are generated by this coil, 1. positive voltage: q1, Q3 is an upper tube, Q2 and Q4 are lower tubes, and the upper tube and the lower tube are simultaneously conducted; 2, 0 voltage: the upper pipe is closed, and the lower pipe is communicated; 3, negative voltage: the upper pipe and the lower pipe are closed simultaneously; the positive voltage and the 0 voltage are controlled alternately, so that the current of the coil can rise rapidly. The negative voltage and the 0 voltage are controlled alternately, so that the current of the coil can be rapidly reduced.
