The automatic Filling machine completes a series of operations such as counting into plastic square drums, weight filling, automatic capping machine, servo tracking capping machine, automatic labeling machine, automatic inkjet machine, automatic stacking machine, robot palletifier, automatic horizontal strapping machine, automatic sword strapping machine, automatic wrapping film conveying and so on. Realizing the networked centralized visualization of the liquid low-temperature filling operating system, the expected filling effect is achieved, effectively avoiding damage to the equipment, eliminating the overloading phenomenon of the tank truck, effectively reducing the damage to the filling pipeline, and reducing the influence of human operation in the filling operation process. Filling system to each link global scheduling and control, according to the current state of the system, call the GPIO module, control valve switch. Responsible for reading analog information connected to the system, such as temperature transmitters, pressure transmitters, etc. Through the Mod-bus protocol, read the system's connected weighing data information, provide embedded database access, and be responsible for caching peripheral values for the central control module to call.

Filling system adopts microcomputer technology, through RS485 interface, Modbus RTU protocol communication ARM control system, through the choice of working mode, can realize the preset amount, preset volume and arbitrary liquid filling three working modes. The selection and setting of the gas filling process can realize the automatic switching between the artesian-flow mode and the pump filling mode. For the setting of weight parameters, the intelligent judgment of weight can realize the automatic change of pre-cooling and cryogenic pump operating state under the set weight under the operation state of the pump filling, and effectively avoid the damage caused by human judgment or operation error to the filling system. According to the preset filling amount or amount, automatically realize the start and stop control of the filling system, and complete the accurate measurement, display, settlement, printing and other functions of the filling amount, effectively control problems such as overload. The upper and lower limits of pressure, weight, temperature and other parameters are set to realize the emergency cutting function in the abnormal state of the filling pipeline, and effectively avoid the occurrence of accidents. It can realize the function of checking the number of filling, the amount of filling, the amount of filling and automatic accumulation. Through the automatic filling system to realize the automatic control of cryogenic liquid filling, to overcome the safety risks caused by equipment defects and personnel errors, to ensure the safety of cryogenic liquid filling.
