The control system of the quantitative filling machine mainly consists of PLC, touch screen, actuators, and detection elements. The computer downloads the program and monitors the operation of the equipment through the Ethernet PLC on-line. The touch screen communicates with PLC through Modbus485 communication protocol, displaying the running status of the equipment, and starting and stopping the equipment to set the operating parameters and other operations. The actuator is responsible for the execution of the PLC instructions, the specific implementation of the corresponding action. The detecting element sends the status and parameters of the equipment to the PLC.
020-34563445The controller used in the automatic Filling machine is Siemens S7-200 programmable controller, Filling system using dual CPU to form a redundant system, provided by Siemens STEP7MicroWinV4.0SP6 programming software as a human-computer interface to write the program debugging program, download the program and so on. Machine and PLC experimental machine with a / PPI cable connection for communication, and set the corresponding parameters. Connect the machine with PLC using RS-485 bus.
The filling machine has a large storage capacity, fast operation and processing speed, good compatibility. In order to ensure the accuracy and reliability of the action of each part of the device in the filling process, it is necessary to control the sensors, relays, switches and solenoid valves through the PLC program. The filling materials are entered and weighed, as well as recorded, to realize the management of material feeding. In order to realize accurate production and avoid production losses and even accidents caused by human errors in the production process, the correctness of the implementation is ensured by means of checking and confirming the instruction information of the feeding process and the filling process, electronic signatures of the important steps, and constraints on the identification of the material and container codes.
