As shown in Figure 4 and Figure 5, two setting-up time relays of the present embodiment adopt the two repetitive cycling time relays of setting of JSS48A-S, it can preset T1, two time delay periods of T2, after switching on power, relay is first by preset T1 period trigger, with second of time point flicker, control relay be failure to actuate (release position) now; When reaching T1 preset value, control relay contact adhesive indication light, represent that control relay is in attracting state, T1 demonstration simultaneously disappears steady, and then relay is pressed the preset trigger of T2, when arriving T2 setting value, T2 and adhesive indicated number disappear surely simultaneously, trigger, control relay is again in release position, and relay will circulate according to preset delay value like this.When inputting reset signal (be about to pig-tail wire 1., 3. short circuit) in time delay process, relay will be got back to the initial condition of T1=0, and control relay is in release position; When inputting halt signal (be about to pig-tail wire 1., 4. short circuit) in time delay process, relay is by the mode of operation remaining on while suspending.In Fig. 4, P1 represents the adhesive indication of time relay contact, and P2 is that T2 shows, P3 is a second flicker indication, and P4 is that T1 shows, P5 is T1 set of time and choosing period of time, and P6 is T2 set of time and choosing period of time.In Fig. 5, No. 2 terminals are power supply negative terminal, are for No. 7 power positive end.
Before use, need first set T1 and the delay time of T2 period, the present embodiment is set T1=T2=3 second, and meter counter reset time is not more than the delay time of T1 and T2 period.The needs of controlling according to system, reasonably set time relay T1, the time value of T2 period, and the time-out of two setting-up time relays, reset are just can be achieved after meeting certain condition.
Principle of work of the present invention and process are as follows: the cable 13 on draw drum 1, under the driving of unwrapping wire motor 2, after guide wheel 15 and metering pinch roller 5, then passed through wire carrier 7 to first take-up reels 8 or the second take-up reel 9 carries out take-up.Metering approach switch 6 is as the instrument of metering length of cable, when take-up reel rotates, cable drives metering pinch roller 5 to rotate, after the metering signal that collects by metering approach switch 6 realize counting, when the setting value of meter counter equates with displayed value, the output relay action of meter counter, the two setting-up time relays of this signal control are realized and being suspended, and send a control signal, certainly, for this signal can be disappeared after arriving one section time at once, meter counter output need be set and automatically reset the time.
Double plate handover control system control principle of the present invention is as follows:
Initial condition: when power turn-on, the coil of two setting-up time relay 1KT obtains electric, 1KT first presses the preset time trigger of T1, and now meter counter does not also start counting, suspend not adhesive of control relay K2, a normally closed contact of K2 be connected to 1KT 1., 4. number terminals, realize 1KT and in the preset time, carried out time delay time-out at T1, the state of the T1 period time delay that makes 1KT in suspending, only when K2 adhesive, its normally closed contact disconnects, and could allow the time that T1 period of 1KT continues while suspending continue time delay.
1KT is halted state at initial condition, its normally closed contact is through the normally closed contact of the second take-up starting relay K6, make the coil of the first take-up starting relay K5 obtain electric, met and only had 1 take-up reel first to bring into operation, no matter that is to say which kind of situation, so long as power turn-on, must be the first magnetic clutch first electric work.
The first take-up reel switches to the second take-up reel: when initial condition, the first take-up starting relay K5 coil obtains electric, when stepping on foot-operated switch (or pressing start button S2), foot-operated startup control relay K4 adhesive, take-up start and stop relay K 1 coil obtains electric, the operation of take-up motor, 1H indicator lamp is bright simultaneously.
When the displayed value of meter counter equates with setting value, the output relay action of meter counter, suspend control relay K2 and obtain electric adhesive, take-up start and stop relay K 1 dead electricity, take-up motor is out of service, and 2H indicator lamp is bright, the normally closed contact of K2 disconnects simultaneously, make the time that T1 period of 1KT continues while suspending continue time delay, reaching T1 during preset time, the normally closed contact of 1KT disconnects, and then make the first take-up start K5 coil losing electricity, the first magnetic clutch dead electricity, the open contact of 1KT is closed, the second take-up starting relay K6 coil obtains electric, the second magnetic clutch obtains electric, realize the first take-up magnetic clutch to the switching of the second take-up magnetic clutch.
When the T1 of 1KT arrives the preset time, 1KT starts to be converted to T2 period state delay by T1 period state, and when there is no outward sign input, 1KT carries out time delay by the preset time of T2 period.
After meter counter output relay action a period of time (the present embodiment is 2~3 seconds), meter counter automatically resets, ready for starting to count again.
When 1KT is converted to T2 period time delay state by T1 period time delay state, meter counter resets and also carries out simultaneously, as long as set of time is best, 1KT is when T2 period state, K2 is dead electricity thereupon, the normally closed contact of K2 at once short circuit 1KT 1., 4. number terminals, realize the time-out of T2 period time delay state, make the second take-up starting relay K6 continue electricly, and then it is electric that the second magnetic clutch is obtained.
The second take-up reel switches to the first take-up reel: the second magnetic clutch obtains the electric operation that realizes the second take-up reel, while only having the displayed value that again occurs meter counter to equate with setting value, the T2 period time delay state of 1KT is switched to T1 period time delay state, realize the second magnetic clutch to the switching of the first magnetic clutch, so circulation, does not stop to realize circular flow as long as produce.
As long as each, start and step on foot-operated switch, can realize very easily operation; If occur, length on draw drum is not during required fixed length, press stop button S1, take-up motor is out of service, because the reset button S1 of stop button S1 and time relay 1KT is compound button, as long as press the button S1, time relay 1KT can reset, and running state gets back to initial condition, and take-up just brings into operation from the first take-up reel.
