After the entire operation flow is set to execute three cycles, the PLC controller Control the inverter to stop output and the operation ends.

During operation, if the hydraulic oil pump motor M1 is overloaded, the PLC controller controls the inverter to stop output, and causes the squeegee to compress the electromagnetic coil S2, the squeegee to open the electromagnetic coil S1, the upper electromagnetic coil S4 and the electromagnetic under the material The coil S3 is de-energized and the operation ends; after 1S, the overload is automatically reset, and the hydraulic oil pump motor M1 can be started normally; during the compression process of the scraper, the differential change is normal motion, that is, when the inverter output frequency is 50 Hz, if the hydraulic oil pump motor When the current of M1 rises to more than 2 times of rated current and keeps reaching 3 seconds, the compression in the compression box is full, the PLC controller controls the coil of the full box relay K4 to be energized, and the normally open contact of the full box relay K4 is closed. The full box indicator light D2 is on and the operation is finished. At this time, since the normally closed contact of the full box relay K4 is disconnected, even if the start button SB1 or SB2 is pressed, the squeegee circulation operation cannot be performed, and if the hydraulic oil pump motor is to be made M1 work, only use the electronic key to open the electronic lock BK1, in order to make the PLC controller control the inverter output 50Hz power supply, drive the hydraulic oil pump motor M1 to work.

After the garbage compression box is full, use the electronic key to open the electronic lock BK1, so that the PLC controller controls the inverter to output 50Hz power, drive the hydraulic oil pump motor M1 to work, press the squeegee open button SB7, so that the squeegee opens the electromagnetic coil S1 When the squeegee is opened, the squeegee is in proximity to the switch SW1 to send a signal to energize the coil of the in-position relay K5 on the squeegee, and the first normally open contact of the squeegee in place relay K5 K5-1 and the second normally open Contact K5-2 is closed. Pressing the button SB3 on the pick-up, the electromagnetic coil S4 on the material is energized, and the lifting cylinder 8 drives the lifting hopper to rise. When the lifting hopper is raised into position, the feeding device is in place to approach the switch SW2 to send a signal to raise the material to the relay K6. The coil is energized, and the first normally open contact K6-1 and the second normally open contact K6-2 of the feed-on relay K6 are closed. Pressing the lift up button SB5 causes the lift upper solenoid S6 to be energized, and the lift cylinder 6 drives the lift bracket 5 to move upward. When the lift bracket 5 is lifted into position, the lift up position proximity switch SW3 signals The coil of the lift-up relay K7 is energized, and the first normally open contact K7-1 of the lift-in relay K7 is closed.

When the first normally open contact of the on-position relay K5 of the squeegee and the first normally open contact of the in-position relay K6 at the same time are simultaneously closed, the lift upper electromagnetic coil S6 can be powered, and the squeegee can be prevented from being compressed or When the hopper is in the loading state, the lifting bracket 5 is lifted up to cause damage to the equipment. When the second normally open contact K5-2 of the on-position relay K5, the second normally open contact K6-2 of the in-position relay K6, and the first normally open contact K7-1 of the lift-in relay K7 When closed at the same time, the pull box allows the indicator light D1 to be illuminated, and the pull arm can pull the compression box away.

After the fan open button SB8 is pressed, the coil of the air-cooled contactor K1 is energized, and the contact of the air-cooled contactor K1 is closed, so that the motor of the hydraulic oil cooling fan works; during the operation, if an emergency situation occurs, an emergency When the stop button is pressed, or the high oil level switch LE1 and the low oil level switch LE2 are triggered, the PLC controller controls the frequency converter to stop output, and causes the squeegee to compress the electromagnetic coil, the squeegee to open the electromagnetic coil, and to raise the electromagnetic coil. Both S4 and the electromagnetic coil S3 under the material are de-energized.

The PLC controller can use the S7-200 PLC controller produced by Siemens Electric.
