CPS-45
System : Monitoring for racks / barrels plating machines. Movements
diagrams
To manage
the hoists movements in order to obtain the maximal
production output while respecting the imposed immersion
times, represents by far the most difficult problem for the
automation of this type of machines.For productions with few variations
a system based on predefined cyclical diagrams
is certainly the most appropriate solution. But if a greater or
even a total flexibility of production is required, the
problem changes fundamentally: the system must calculate in real
time the sequencing of movements. The priority based
control systems give satisfactory results as far as the carriers
disponibilities are available in abundance, otherwise the immersion
overtimes become excessive.

In order to avoid these out-of-control situations,
the CPS-45 calculates, at
the introduction of each new load but also at regular time intervals,
the whole structure of future movements of the racks actually
in production or to be treated. The CPS-45 is also provided with
a powerful tool for calculation and graphic edition of cyclic
diagrams for any defined sequence. It is thus easily possible
to work either in random mode, or in pure cyclic mode.
