Solvent filling machine takes advantage of the high measurement accuracy of the electronic scale, connects the electronic scale signal sensor with the data line of the weighing control instrument, and realizes manual/automatic selection, start, stop, emergency stop and manual opening of the pump solenoid valve by adding a standard button. By setting the display output attribute of the label, the setting of the filling quality can be displayed in real time. The configuration monitoring screen such as the setting of the number of filling bottles and the display of the current number of filling barrels can complete the monitoring of the operating status of the filling system.
020-34563445Weighing Filling machine adopts the most widely used in industrial control to adjust the weight for actual control, according to the weight deviation, through the frequency converter to adjust the speed of the Electronic scale, adjust the quantity, so that it is equal to the set value, complete the automatic filling process. The controller used is the Siemens S7-200 programmable controller, which uses double CPU to form a redundant system. The programming software provided by Siemens is used as the man-machine interface to write programs, debug programs, download programs, etc. The machine communicates with the PLC experimental machine by connecting with a /PPI cable, and the corresponding parameters are set. RS-485 bus is used to connect the machine with PLC.
The weighing control system has large storage capacity, fast computing and processing speed, and good compatibility. In order to ensure the accurate and reliable action of each part of the filling process, it is necessary to control each sensor, relay, switch and solenoid valve through PLC program. Fill the material input weighing, and record, to achieve the management of material feeding. In order to achieve accurate production and avoid production losses and even accidents caused by human operation errors in the production process, we ensure the correctness of execution by checking and confirming the instruction information of the feeding process and filling process, electronic signature of important steps, material and container code identification constraints.
