Control and display method and device of working state of weft detector of spinner

Abstract

The invention relates to a control and display method and a device of a working state of a weft detector of a spinner. Two rows of regularly-arranged light-emitting diodes or a single row of double-color light-emitting diodes form a display, wherein one row (or color) of light-emitting diodes is used for displaying a square wave pulse weft signal IN, and the other row (or color) of light-emittingdiodes is used for displaying the phase position and the breadth of an adjusted FT' time sequence signal. The phase position and the breadth of the FT' can be adjusted through adjusting a phase position adjustment potentiometer PS-D and a breadth adjustment potentiometer PS-W, so that the tolerance of the FT' to the IN signal is adjusted. According to the state of each light-emitting diode lightened by the display after the shutdown of a spinner, the shutdown reason can also be directly observed. The control and display method and the device have the beneficial effects that the adjustment is convenient, the display is direct, and the control is reliable; and the work efficiency of the spinner can be effectively improved, and the product quality of fabrics can be improved.

Description

technical field [0001] The invention relates to a control and display method for weft detection, in particular to a control and display method and device for the weft detection working state of a textile machine. Background technique [0002] We know that the weft detecting technology is the core technology of the electronic control system of textile machinery, and its performance directly affects the working efficiency of the textile machine and the quality of the fabric. For similar spinning machines such as water-jet spinning machines and air-jet spinning machines, when the spinning machine is running, it drives the stop iron to rotate, and the stop iron blocks the proximity switch within a certain angle range (determined by the arc length of the stop iron), so that the proximity switch outputs The time series signal FT with a certain width is sent to the weft detection control unit, and the FT signal is adjusted by the phase shift adjustment circuit and the width adjustm...

AI Technical Summary

Problems solved by technology

The biggest disadvantage of this display method is that it is not intuitive. Not only the operator of the textile machine is not easy to grasp the adjustment method, but even the electrical appliance manufacturer cannot adjust it accurately, because it is impossible to visually see the width of FT' and the relative relationship with the IN signal. The position can only be adjusted by feeling. If the adjustment is not good, the spinning machine will stop empty (the phenomenon of stopping when the weft insertion state is normal), or the broken (short) weft does not stop (the weft yarn is broken or short and does not stop). , thus seriously affecting the working efficiency of the spinning machine and the quality of the fabric
