US 6,378,575 B1 · Method for controlling the filling of containers with a flowable product and filling installation implementing said method

Abstract

A method and an installation for controlling the filling of containers (5) with a flowable product in a filling installation has a product reservoir (1) and a filling unit (3) for simultaneously filling several containers (5). The method consists in: measuring the total real flow rate of product delivered by the filing unit (3) to the whole set of containers (5); detecting the number n of containers (5) being filled in the filling unit (3); displaying a theoretical flow rate q of the individual filling of the containers (5); comparing the total real flow rate measured and the theoretical flow rate n.q; and, correcting, if necessary, the total real flow rate to make it coincide with the theoretical flow rate. The operation of the installation is thereby adapted to the exact number of containers being actually filled simultaneously, with no significant variations of real individual filling flow rates.

Method of controlling the filling of containers (5) with a flow product in a filling installation comprising a product reservoir (1) and a filling unit (3) enabling several containers (5) to be filled simultaneously, characterised in that:

the total real flow rate of product delivered by the filling unit (3) to all the containers (5) is measured,
the number n of containers (5) being filled within the filling unit (3) is detected,
a theoretical individual filling rate q for the containers (5) is displayed,
the measured total real flow rate and the theoretical flow rate n.q are compared and
if necessary, the total real flow rate is corrected to bring it into line with the theoretical rate,
as a result of which, operation of the filling installation can be adapted to the exact number of containers effectively being filled simultaneously, without any significant variations in the real individual filling rates.
