Based on the magnetic seed-metering principle, a new magnetic plate-type precision seeder and seeding production line were developed to meet the requirements of precision seeding. The control system was designed based on Programmable Logic Controller (PLC) and Mico Controller Unit (MCU). Automatic programming techniques, sensor technology, acceleration and deceleration control of step motor were integrated into the system. The PLC control system controls the workflow of the production line to realize accurate positioning of the tray and its coordination. The MCU control system controls the flip of the sowing board, as well as the up-and-down movement of the seed case for whole tray seed-filling and sowing. Seeding tests for the magnetic powder coated rape seeds showed that the rates of single-seeding, over-seeding and miss-seeding were 90.2778%, 4.6875% and 5.0347% respectively. The seeding speed was up to 14s per tray. This result meets the requirements of precision seeding.

A new magnetic plate-type precision seeding production line and its control system were designed based on the magnetic seed-metering principle. The control system is consisted of DVP-40ES Programmable Logic Controller and LJD-51-XB+ Mico Controller Unit. The PLC control system controls the working flow of the production line. The MCU control system controls turnover movement of the sowing board and up-and-down movement of the seed case for whole tray seed-filling and sowing. Seeding tests for the magnetic powder coated rape seeds showed that the rate of single-seeding, over-seeding and miss-seeding were 90.2778%, 4.6875% and 5.0347% respectively. The seeding speed was 257 trays per hour, an average of each tray with 14s. It meets the requirements of precision seeding. The system design is reasonable and reliable.

Plc Control System

The system uses the PLC controlling step motor to propel the welding oscillator. It adopts the PLC to output pulses, which frequency is precise, so it is convenient to control the direction, and the mechanic part of the oscillator is simplified. At the same time, because of the step motor’s precise step and it is dependable driving, the welding oscillator controlled by this system is convenient to control, not only the oscillation velocity but also the standstill time at each point. The system’s stability can meet the practical need of the welding perfectly.

Packing Efficiency

In order to solve the problem of packing and packing on the soft package in the pipeline, we use PLC system to control the robot. The step motor and the push rod motor cooperate with each other to realize the space movement. The vacuum sucker can firmly absorb the target and realize the transportation and packing of the target. To solve the problem of heavy workload of the soft packing line, wasting the manpower and material resources, we change the past hard grab transport mode and use the vacuum sucker to absorb the soft package to improve the packing efficiency. As for transporting soft package goods, the vacuum sucker has characteristics of small wear, fast speed, light and convenience. PLC control system greatly improves the accuracy of its moving objects, the robot is more efficient and practical.
