Press start key, the signal of start key S2301 enters interface J2284, and shown in voltage waveform Fig. 5 (a), the present embodiment and battery-conserving switch duty have nothing to do, and is described under only considering the condition that the motor of weaving rapier loom operates always, signal is through D2235, U2207 input, setting U2207 input and U2208 output are electronegative potentials, during another input step-down current potential of U2207, U2207 output is that high potential is connected to U2204 input, U2204 output is electronegative potential, U2204 output is discharged to C2250 by ll2252, after 0.1 second, the U2201 output that input connects with C2250 becomes high potential, U2203 input connects with U2204 output, another input of U2203 connects with U2201 output, electronegative potential moment is become at U2204, U2203 output is high potential, after U2201 output becomes high potential, U2203 output becomes electronegative potential, U2203 output keeps the time of high potential to be 0.1 second, complete fixing limit for width, shown in voltage waveform Fig. 5 (b), U2203 output passes through LED2229, R2275 provides electric current to BG2219 base stage, BG2219 conducting.
U2203 output connects with U2209 input, U2209 output is electronegative potential, the U2202 output connected with U2209 output is high potential, electric current is provided to BG2222 base stage by R2258, BG2222 conducting, there is provided electric current by input interface J2285 to the startup optocoupler S2302 in weaving rapier loom circuit arrangement, meanwhile, in weaving rapier loom circuit arrangement, the output interface 5 of brake is electronegative potential.
Battery-conserving switch input interface J2288 connects with brake input interface, BG2225 base stage can not obtain electric current remain off from R2273, LED2231 again, the U2211 output connected with BG2225 colelctor electrode is electronegative potential, U2210 input connects with U2211 output, U2210 output high potential, voltage on D2232 and C2247 is equipotential, and U2209 output is electronegative potential, and BG2220 still keeps conducting.
And then in weaving rapier loom circuit arrangement, brake output interface 5 becomes high potential from electronegative potential, BG2225 base stage obtains base current and conducting by LED2231, R2273, U221 1 output end voltage takes a turn for the worse and becomes high potential, U2210 output becomes electronegative potential, electric charge on C2247 by D2232, U221 0 output electric discharge, U2209 output becomes high potential immediately, U2202 output becomes electronegative potential, BG2220 ends, and starts pulsewidth again by limit for width. shown in voltage waveform Fig. 5 (c) after limit for width; The voltage oscillogram 5(d of the brake of weaving rapier loom circuit arrangement output interface 5) shown in; Due to the voltage waveform of Fig. 5 (c) change at random, this pulsewidth changes between 0.02 ~ 0.08, then change because the various factors such as vehicle condition is different, temperature is different, the degree of tightness of wiring are different; One is had to be fixing, such as can Circuit tuning parameter. interface 5 voltage can be set and cut off startup pulsewidth again when 8V.
Starting pulsewidth main feature is:
1, start when weaving rapier loom normally works shown in pulsewidth Fig. 5 a, b, c, shown in brake interface 5 pulsewidth Fig. 5 (f).
2, weaving rapier loom warp connects loosely, starts and break instantaneously, does not connect at all, or press shown in start key work pulsewidth Fig. 5 a, b, c, shown in brake interface 5 pulsewidth Fig. 5 (d) by mistake after warp broken string.
As can be seen from Fig. 5 a, b, c, d, f: under weaving rapier loom is in any duty, start pulsewidth automatically to change between 0.02 ~ 0.08 second according to the difference of weaving rapier loom vehicle condition, the time leaving the instruction of weaving rapier loom execution start-up operation for is few, and the time performing start-up operation instruction is changeless, the possibility knitted a net almost can drop to 0.
embodiment 2
Shown in circuit block diagram 1, circuit theory Fig. 8.
As long as go inquiry weaving rapier loom to knit a net reason to weaving mill, machine maintenance will be said, menopause tablet can fall knitting a net of causing and can't resolve, and this is beat a retreat in the face of difficulties for people out of the picture, once someone adopted photoelectric method to control and knitted a net, in machine maintenance workman, leave deep impression.
In order to find the reason knitted a net, carry out careful sight to weaving rapier loom to look into, during normal work, weaving rapier loom circuit arrangement output interface and brake phase contact (numbering 5) waveform are as shown in Fig. 4 (a), figure (b) is voltage waveform under the state of knitting a net, and the weaving rapier loom reason that knits a net is:
1, weaving rapier loom is mounted in ground, gravity along with the prolongation loom of time makes ground generation creep, and when loom work, has certain vibration, it is multiple directions that this vibration produces stress distribution, and ground producing weaving rapier loom amplitude after multiple directions are crept can increase;
2, menopause tablet majority is done by metallic iron, and metal oxide layer increases progressively in time, and resistivity strengthens:
3, in use, machine maintenance will adjust crawl parameter, reduces brake reaction speed;
4, under brake mechanical structure Long-Time Service, because metal fatigue damage makes retro-speed slow down:
5, the density of the warp of cloth is also affect the probability that knits a net, although this by menopause tablet instability occur knit a net only account for loom sum less than 5%, but there is very large fright effect to factory owner, textile worker, be exactly a sheet of once knit a net, process once knits a net often more than l hour, is not very large for the phenomenon possibility of falling not fall down to knit a net of menopause tablet in legend.
6, in weaving rapier loom circuit arrangement, brake, clutch 24V power supply electrochemical capacitor capacity such as to diminish at the factor.
When weaving rapier loom performs start-up operation instruction, numbering 5 is high potentials, this current potential passes through J2288, LED2231, R2273, BG2225 base stage, BG2225 conducting, C2244 be the input that electronegative potential .U2206 and C2244 connects is electronegative potential by D2237 and the BG2225 colelctor electrode .C2244 that connects equally, another input of U2206 connects with J2280, J2280 connects with weaving rapier loom stop over checkout gear interface ll pin, moment is fallen down at menopause tablet, the output that U2206 input becomes electronegative potential .U2206 becomes high potential, BG2222 conducting is made by R2266, J2280 is fixed at low-potential state. output waveform is as Fig. 4 (d) pulse front edge (decline): be input to weaving rapier loom stop over checkout gear interface stop over signal and make weaving rapier loom stop start-up operation instruction, meanwhile, the voltage of brake interface 5 soil becomes electronegative potential from high potential, J2288 becomes electronegative potential .BG2225 equally to be ended owing to can not get base current, BG2225 colelctor electrode becomes high potential instantaneously, C2244 is connected by D2237 and BG2225 colelctor electrode, D2237 oppositely ends.
Power supply is charged to C2244 by R2262, R2261. when the voltage rise on C2244 becomes electronegative potential to the threshold values U2206 output of U2206 input that connects with it, BG2222 ends, waveform is as Fig. 4 (d) pulse back edge (rising), and two directions' inputing output device of holding concurrently completes whole control network process.
embodiment 3
When Fig. 8 circuit J2280 break or need not, two directions' inputing hold concurrently output device lost efficacy, it is unstable that Fig. 8 circuit solves menopause tablet, shown in control network technology method block diagram 3, this method and two methods above different, the first two embodiment control network control network method and battery-conserving switch duty have nothing to do, and this embodiment method is relevant with battery-conserving switch state.
Press start key S2301, start-up operation signal enters battery-conserving switch interface J2284, D2233 conducting, the U2212 input connected with R2267 is placed in electronegative potential, U2212 output is high potential, U2212 output is charged to C2245 by D2277, voltage rise on C2245 is to U2216 input upper limit triggering level, U2216 output becomes electronegative potential, U2217 input is made to be clamped on electronegative potential by D2241, U2217 becomes high potential, U2217 output provides base current by R2265 to BG2224, BG2224 conducting, relay Q2274 obtains electric, contact K2296, K2297, K2298 closes, with interface J2293, J2294, the motor DDJ2300 that J2295 connects starts to rotate, meanwhile, start key signal is by D2235 to U2205 input, U2205 output makes its U2208 input keep high potential before start key unclamps by D2238.
U2205 output is charged to C2248 by D2239 simultaneously, when the voltage rise on C2248 is to U2214 input upper limit triggering level, U2214 output becomes electronegative potential, electric charge on C2249 is discharged by R2271 to U2214 output, when voltage drop on C2249 is to U2215 input lower limit triggering level, time delay (R2271, C2249) after 0.1 ~ 0.2 second, its output becomes high potential, the U2204 output connected with U2215 output becomes electronegative potential, then limit for width is fixed, automatic limit for width provides enabling signal to sword reed machine circuit arrangement input interface 16 again, weaving rapier loom performs start-up operation instruction, weaving rapier loom output interface 5 becomes high potential, pass through LED2231, R2273, base current is provided to BG2225, BG2225 conducting, one end that R2259 and BG2225 colelctor electrode connects is electronegative potential, to keep U2217, U2218 duty is constant, motor long time running.
After the menopause tablet in weaving rapier loom warp-stop motion falls down, enter weaving rapier loom circuit arrangement input interface 11, weaving rapier loom circuit arrangement output interface 5 becomes electronegative potential moment from high potential, by battery-conserving switch interface J2288, low-potential signal is passed to battery-conserving switch, BG2225 ends, power vd D passes through R2262, R2259 to U2217 input, R2259 " R2260, U2217 duty takes a turn for the worse, U2217 output becomes electronegative potential, BG2224 ends, relay Q2274 dead electricity, contact K2296, K2297, K2298 discharges, motor gradually rotating speed slows down, when motor rated speed, weaving rapier loom Oscillation Amplitude is fixing, after motor speed declines, weaving rapier loom Oscillation Amplitude declines, also reducing by amplitude on signal plate, be applied to signal plate pulsewidth to increase, on-position is in after brake action, complete control net function.
Control net effect analysis: when knitting a net, menopause tablet is very unstable on signal plate, unstable root is that cloth machine has oscillation phenomenon, the amplitude of vibration and cloth machine elastic modelling quantity, quality, the many factors of motor speed are relevant, after motor is cut off the electricity supply, rotating speed lowers at once, an important change, cloth machine amplitude diminishes, the menopause tablet state of knitting a net must rely on cloth machine amplitude and exist, after cloth machine amplitude diminishes, the menopause tablet pulsewidth on signal plate that drops is widened, weaving rapier loom output interface 5 becomes the time of electronegative potential in increase, brake enters on-position immediately.
The method and technology effect of this control net is a little less than embodiment 2, and can also see the vestige found and knit a net, now just can check whether battery-conserving switch mouth J2280 and weaving rapier loom stop over checkout gear 11 break, whether two directions' inputing output device of holding concurrently has problem.
