The weighing and Filling machine is mainly used to input and weigh the incoming materials and record them to achieve the management of material feeding. Material input: Provide material information through manual or automatic information filling machine, weigh the input material, and record the input information of the material. The control part of the filling valve is the control system module. Siemens PLC is responsible for the safety function, speed control and level control of the high buffer tank. The PLC control system consists of Profibus bus and ASI bus and is responsible for the control of the filling valve gauge cylinder level, the tank filling level control, the pneumatic control of the filling valve, and the control of the filling Angle and time.

The Filling system adopts the combination of weight measurement and oil filling. The oil cylinder carries a small bracket through the gap between the conveyor rolls to lift each oil drum in the group respectively to realize weight measurement and compensation filling. The whole process is controlled by PLC. When the pallet carrying the initially loaded oil drum reaches the metering and compensation area, the PLC is triggered to control the cylinder carrying platform and the small support to rise, the small support respectively lifts each small pallet and the corresponding oil drum, and the large pallet still stays on the conveyor. When the travel switch installed on the platform runs to the corresponding position on the frame, the oil drum reaches the high point, then the PLC is triggered to read the reading of each gravity transmitter, and the input channel is closed after the reading action is completed; The PLC controller compares the original reading mass corresponding to each oil drum with the set value. When the filling quality of some oil drums does not match, the PLC controller calculates the corresponding compensation filling time and triggers the compensation filling. Wait for all the oil drums that need to be filled to complete the compensation canning, at this time the PLC control cylinder reset; Each oil drum drops synchronously with the small pallet onto the large pallet that stays in place.
