Filling valve control system shared by electronic liquid level meter type glass bottle, pop can and PET bottle

Abstract

The invention discloses a filling valve control system shared by an electronic liquid level meter type glass bottle, a pop can and a PET bottle, and relates to the technical field of automatic filling. The system comprises a PLC control unit, a filling valve assembly unit, an electromagnetic valve assembly unit and a man-machine interface unit; and the filling valve assembly unit comprises a base,a float bowl, multiple control air cylinders, an air return needle and a liquid level meter, wherein the float bowl and the multiple control air cylinders are installed above the base, the air returnneedle is installed below the base, and the liquid level meter is installed at the top end of the float bowl. According to the filling valve control system, control is stable through programming of acontrol mode of a state machine, and high control precision and good repeatability are achieved through adopting a high-speed response electromagnetic valve assembly, a high-precision digital quantity signal of a magnetostriction liquid level sensor through a high-speed bus as well as a strict bus-based scanning mechanism.

Description

technical field [0001] The invention belongs to the technical field of automatic filling, in particular to a control system for filling valves shared by electronic liquid level gauge glass bottles, pop cans and PET bottles. Background technique [0002] With the improvement of people's living standards, everyone's pursuit of beverages, beer, mineral water, etc. has gradually become more diversified and differentiated, not a single product. Craft beer and various customized beverage products, which are now popular in the world, are a good example. Manufacturers are eager to need a filling equipment that can adapt to different bottle types and different packaging materials to meet production needs. [0003] The idea of ​​this application document "Electronic liquid level gauge glass bottle, can, PET bottle shared filling valve control system" comes from the vigorous development of craft beer in recent years. Craft beer filling equipment generally requires less land occupation...
