When the piston rods of the other two electric telescopic rods M1 are positioned at the front dead center, the push plate and the upper end of the front side of the frame baffle of one set of electric conveyor body M2 are transversely positioned on the same plane. The trigger sub-circuit comprises a time relay module A3 and a relay K1 which are connected through circuit board wiring, K2 and K3, and is connected with a photoelectric switch A2 through a wire, a photoelectric switch A2 positive power input end 1 pin and a first relay K1 control power input end, a second relay K2 control power input end, a time relay module A3 positive power input end 1 pin is connected, a power output end 3 pin of the photoelectric switch A2 is connected with a first relay K1 positive power input end, a first relay K1 normally open contact end is connected with a time relay module A3 positive trigger signal input end 3 pin, a second relay K2 normally open contact end is connected with a third relay open positive power input end, a photoelectric switch A2 negative power input end 2 pin and three relays K1, K2 and K3 negative power input ends, a negative power input end 2 pin of the time relay module A3 and a negative control power input end 4 pin are connected.

As shown in fig. 1 and 2, after the 220V ac power supply enters the power input terminal of the regulated power supply A1, the regulated power supply A1 will output a stable dc24V power supply at pins 3 and 4 under the action of its internal circuit to enter the optoelectronic switch and the trigger sub-circuit. After the power switches of the two sets of electric conveyor bodies M2 are turned on, the two sets of electric conveyor bodies M2 are electrified to work, and the parts on the conveying belts are conveyed backwards. When the part is conveyed to a plurality of rotating tubes 9 through a first set of electric conveyor body M2 and then back (because the conveying belt of the electric conveyor body conveys the part forwards, the part can rotate on the rotating tubes 9 and move to the right end, the buffer plate 6 mainly limits and buffers the part movement through the elastic acting force of the spring 5), the part is close to a position (for example, 5 centimeters) before a photoelectric switch A2 detection head in front of the buffer plate 6, 3 pins of the photoelectric switch A2 output high level to enter the positive power input end of the relay K1, then the relay K1 is electrified to attract the control power input end and the normally open contact end to be closed, the positive electrode of the 24V power supply enters the positive trigger signal input end of the time relay module A3, then, 9 pins of the power output end of the time relay module A3 output a period of power (for example, 12 seconds) to enter the positive power input end of the relay K2, and then the relay K2 is electrified to attract the control power input end and the normally open contact end to be closed.

Then PLC is electrified back interval 4 seconds, control another two sets of electric telescopic handle M1 positive and negative poles and be electrified for 4 seconds, like this, two sets of electric telescopic handle M1's piston rod promotes the push pedal to move to the rear end, and then push pedal 4 promotes the part, transports on the conveyer belt of the electric conveyor body of second set of work, this part is carried to next process. After the PLC is electrified for 8 seconds, the four sets of electric telescopic rods M are controlled to be electrified and work for 4 seconds to stop (the four sets of electric telescopic rods M are electrified with negative and positive poles or positive and negative poles), so that piston rods of the four sets of electric telescopic rods M drive the frame 2 to return to the initial position downwards or upwards after the four sets of electric telescopic rods are electrified and work, and preparation is made for conveying the next part to the second set of electric conveyor body; and simultaneously controlling the negative pole and the positive pole of the other two sets of electric telescopic rods M1 to be electrified for 4 seconds, so that the piston rods of the other two sets of electric telescopic rods M1 drive the push plate to move towards the front end, and the push plate 4 returns to the position contacted with the inner side of the front end of the frame to prepare for conveying the next part to the second set of electric conveyor body. After 12 seconds, 3 feet of time relay module A2 stop output power, like this, time relay module and PLC etc. are whole to lose the electricity, and its control power input end and normally closed contact end are closed after relay K3 loses the electricity, and like this, first set of electric conveyor body M2 gets electric work once more and carries the part up the frame. The above process is continuously circulated, and the components on the first set of electric conveyor body can be continuously conveyed to the conveying belt of the second set of electric conveyor body.
