Technical field
The present invention relates to a kind of device that is used to show the weft yarn state of flight of air-jet loom, its state of flight refers to the situation of change of Weft yarn flight stretching force numerical value corresponding to the loom main shaft corner.
Background technology
The used in jet loom air-flow is realized wefting insertion, and the flight course of weft yarn is divided into start-up period, free flight stage and constraint mission phase.The state of flight of weft yarn can arrive the time and the weft tension of catching the latitude side with weft yarn and describe, on the present air-jet loom, have only and measure the sensor that weft yarn arrives the time of catching the latitude side, its principle is to utilize optical reflector to survey the time of advent of weft yarn, does not also measure the sensor and the tension force display unit of Weft yarn flight stretching force.Tension state and time course that the three phases of weft yarn flight is corresponding different are respectively only measured weft yarn time of advent, can not understand whole wefting insertion processes.Therefore, it is more important the time of advent than measuring weft yarn to measure Weft yarn flight stretching force, understands the fly weft tension in each stage of weft yarn, just can fully understand the weft yarn whole process of flying.Can know to know whether the wefting insertion process is normal from the weft tension state, when changing weft yarn kind and number, can adjust each technological parameter within a short period of time, reach the highest machine efficiency of loom.
Summary of the invention
The object of the invention is exactly that a kind of each when revolution that can show air-jet loom is provided in order to overcome the deficiencies in the prior art, and its Weft yarn flight stretching force numerical value is corresponding to the device of the situation of change of the corner of loom main shaft.
For achieving the above object, the technical solution used in the present invention is: a kind of Weft yarn flight stretching force display device, it comprises: the Yarn tension sensor that is used to measure weft tension, be used to handle the weft tension signal regulating panel of the output signal of described Yarn tension sensor, the weft tension arithmetic unit that is connected with the output signal of described weft tension signal regulating panel, the loom master control borad that is connected with the output of described weft tension arithmetic unit, also be connected with the shaft encoder of the corner of the main shaft that is used to detect air-jet loom on the described loom master control borad, also be connected with the display unit that is used to show Weft yarn flight stretching force on the described loom master control borad.
Described Yarn tension sensor comprises with the sensor body that is connected of weft yarn of flight, pastes four foil gauges at the thin-walled place of described sensor body, and four described foil gauges are four brachium pontis of a constant voltage electric bridge.
Described weft tension signal regulating panel comprises and is used for amplifier that the electric current with the signal of Yarn tension sensor amplifies and the A/D converter that is connected with the output of amplifier.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage: the present invention can provide a kind of good reliability, long and simple in structure online weft tension display unit of life-span, is used for measuring in real time and shows the weft yarn adaptability of dynamic weft tension, raising air-jet loom and the control device of optimization air-jet loom.

The specific embodiment
Below the specific embodiment of the present invention is described: referring to Weft yarn flight stretching force display device shown in Figure 1, it comprises: the Yarn tension sensor 1 that is used to measure weft tension that is connected with the weft yarn of flight, be used to handle the weft tension signal regulating panel 2 of the output signal of described Yarn tension sensor 1, the weft tension arithmetic unit 3 that is connected with the output signal of described weft tension signal regulating panel 2, the loom master control borad 4 that is connected with the output of described weft tension arithmetic unit 3, also be connected with the shaft encoder 6 of the corner of the main shaft that is used to detect air-jet loom on the described loom master control borad 4, also be connected with the display unit 5 that is used to show Weft yarn flight stretching force on the described loom mainboard 4, when described display unit 5 showed each revolution of loom, its Weft yarn flight stretching force numerical value was corresponding to the situation of change of the corner of loom main shaft.Wherein said weft tension signal regulating panel 2 comprises and is used for amplifier 21 that the electric current with the signal of Yarn tension sensor 1 amplifies and the A/D converter that is connected with the output of amplifier 21.
Referring to Fig. 2, specifically, described Yarn tension sensor 1 comprises with the sensor body 13 that is connected of weft yarn of flight, pastes four foil gauges 11 on described sensor body 13, four described foil gauges 11 are four brachium pontis (referring to Fig. 3) of a constant voltage electric bridge 12, in the scope of weft tension correspondence, the strain of pasting the thin-walled place of foil gauge on Yarn tension sensor 1 output voltage and the sensor body 13 keeps linear thus.
The flight course of weft yarn is divided into start-up period, free flight stage and constraint mission phase.The corresponding small tension receiving coil peak of start-up period, corresponding minimum tension state of free flight stage, then corresponding maximum tension force of constrained flight stage, and high tensions continues for some time.Only measuring weft yarn time of advent, is the wefting insertion process that can't understand weft yarn.Therefore, it is more important the time of advent than measuring weft yarn to measure Weft yarn flight stretching force, understands the Weft yarn flight stretching force in each stage, just can correctly understand the weft yarn whole process of flying.
The weft tension strain signal spreads out of through weft tension sensor 1, and strain signal is through weft tension signal regulating panel 2 output data signals, and data signal is input to weft tension arithmetic unit 3.Weft tension arithmetic unit 3 has following function: 1) catch and measure weft tension peak value and variation thereof corresponding in the cycle of loom single-revolution, 2) catch or calculate weft tension in the peak value and the mean value in each stage of flight course, 3) determine weft yarn the fly start angle and the termination angle in each stage.The operation result of weft tension arithmetic unit 3 is through loom master control borad 4, the tension force numerical value and the corresponding angle that on display unit 5, show weft yarn start-up period and constraint mission phase, the high-tension corresponding angle that shows start-up period shows beginning angle, angle at the end, the mean tension in constraint stage and the high-tension in weft yarn constrained flight stage.
