Weighing Filling machine only needs to put the same specifications of drums neatly in the designated position, using PLC programmable controller production, filling machine two-stage size material automatic filling mode, with automatic identification of empty drums and empty scale does not fill function, the controller is equipped with manual buttons for all actions, dual window display special filling control instrument, It can display information such as target quantity, filling quantity, number of barrels, time and date.

The automatic filling machine mainly includes front weighing module, double Weighing system, LMC series motion controller, LXM series servo driver and servo motor, and host computer monitoring system. The servo motor is used to control the stroke of the rotor pump, and then the filling quantity is controlled. Before filling, the empty drum weight is obtained by the front weighing module, and after filling, the filling weight is obtained by the back weighing module, and transmitted to the weighing instrument. The weighing instrument will calculate the weight deviation from the filling data in real time, and the filling algorithm will control the large material amount. The weighing system will send the control amount to the servo driver to drive the secondary rotor pump to close the small material amount in advance and then control the small material filling valve.

The upper computer is connected with the weighing instrument through Ethernet to read the filling data in real time, and can set the process parameters to monitor the operation of the production line. After the filling is completed, the grasping manipulator device is driven to accurately locate the designated unit, grab the filling barrel on the material table, transport it to the designated place, and then put it down. The servo motor drives the manipulator, and the high speed pulse output function of PLC is used to realize the accurate stacking control of the manipulator through PTO programming.
