PLANT FOR FILLING A PACKAGING VOLUME WITH GAS

摘要

The invention relates to a plant for packaging cylinders with gas whose nature complies with a given specification. It comprises a set of feed gas sources (18, 20), a network of controlled valves (12), selectively linking the outlet of each feed gas source to the cylinders, and a unit (16) for driving the network of valves and adapted so as to control the state of the valves. The drive unit (16) comprises means (60) of entering a recipe consisting of a sequence of procedures, each procedure describing an elementary task which can be implemented by the valves under the control of the drive unit (16). It furthermore comprises means (62) for processing the successive procedures constituting the recipe. They are adapted to control the network of valves (12) by the sequential implementation of the elementary tasks described successively in the sequence of procedures.
