Controller 3, the 4th intermediate relay, the 5th intermediate relay, the second intermediate relay, third intermediate relay, self-lock protection
Relay and two simultaneously it is electric after can control the duplex solenoid valve of punching machine work, and two duplex solenoid valves use the respectively
One duplex solenoid valve YV1, the second duplex solenoid valve YV2 expression, the first duplex solenoid valve YV1 and the second duplex solenoid valve
One group of second normally opened contact KA2-1 and a third intermediate relay by second intermediate relay is in series on YV2
The third normally opened contact KA3-1 first branch 1 in series, the first duplex solenoid valve YV1 goes here and there with a corresponding first branch 1
Connection constitutes branch 2, and the second duplex solenoid valve YV1 connects and then in parallel with branch 2 again with another first branch 1, and described first
Duplex solenoid valve YV1 is in parallel with the 4th coil KA4 of the 4th intermediate relay, in the second duplex solenoid valve YV2 and the 5th
Between relay the 5th coil KA5 it is in parallel, and the first self-locking normally opened contact KA1-1 of self-lock protection relay and self-lock protection after
The first coil KA1 of electric appliance is connected between power supply+24V and ground terminal, and the 6th of self-lock protection relay is self-locking normally closed
All control power supplys of switch KA1-2 and punching machine are connected between power supply+24V and ground terminal, and self-lock protection relay
The 6th self-locking normally closed switch KA1-2 be also connected between power supply+24V and ground terminal with branch 2, wherein PLC controller 3
Each control port respectively with the second coil KA2 of the second intermediate relay, third intermediate relay tertiary coil KA3, from
Lock the first coil KA1 of protective relay, the 4th normally opened contact KA4-1 of the 4th intermediate relay, the 5th intermediate relay
5th normally opened contact KA5-1, the second normally opened contact KA2-1 of the second intermediate relay, the third of third intermediate relay are normally opened
The connection of contact KA3-1 signal.
Further, the 4th normally opened contact KA4- of the first control terminal X1 and the 4th intermediate relay of the PLC controller 3
1 connection, the second control terminal X2 of the PLC controller 3 are connect with the 5th normally opened contact KA5-1 of the 5th intermediate relay, institute
The third control terminal X3 for stating PLC controller 3 is connect with the second normally opened contact KA2-1 of the second intermediate relay, the PLC control

Point KA2-1 and third normally opened contact KA3-1 people are or other reasons are attracted), the 4th coil KA4, the 5th coil KA5 will at this time
Synchronous to be attracted, the 4th coil KA4 or the 5th coil KA5 actuation are followed by so that the 4th normally opened contact KA4-1 and the 5th normally opened contact
KA5-1 obtains electric actuation, and input point X1, X2 of PLC controller 3 detects signal at this time, through internal processes operation, PLC controller 3
Output point Y3 movement so that the first self-locking normally opened contact KA1-1 of self-lock protection relay obtains electric and self-locking, while self-locking guarantor
The 6th self-locking normally closed point of normally closed switch KA1-2 for protecting relay, which disconnects, cuts off all control power supplys, and punching machine safety stops;If
KA2 (or KA3) burning of contact engages (or other reason machinery are stuck), and the input point X3 (or X4) of PLC controller 3 has signal defeated
Enter through internal processes operation, the output point Y3 of PLC controller 3 acts the first self-locking normally opened contact so that self-lock protection relay
KA1-1 obtains electric and self-locking, while the normally closed point of the 6th self-locking normally closed switch KA1-2 of self-lock protection relay disconnects and cuts off all controls
Power supply processed, punching machine safety stop, if therefore by above structure realize YV1 and YV2 surprisingly it is electric, therewith parallel connection detection after
Electric appliance can also obtain electric, and signal be passed to PLC inter-process, PLC output control KA1 is obtained electric self-locking after processing, will cutting control
Route, to reach the purpose of safety guarantee.
