The method comprises the steps of sequentially taking containers filled in a multi-station filling machine, of weighing each of said taken containers, of comparing said weighing to a preset value for the filling devices of the filling machine and of establishing a correlation between each taken and weighed filled container and the corresponding filling station of the filling machine. In a filling machine comprising a rotation filling apparatus having n filling stations, the control device comprises at least a rotating transfer apparatus arranged in series with the rotating filling apparatus with interposition of at least an intermediary transfer wheel. The rotating transfer apparatus comprises n.sub.1 stations among which n.sub.1 -1 passive stations and a control weighing station provided with a balance, numbers n and n.sub.1 being incommensurable numbers. Controlled actuating means are provided on the circular path of the filling devices of the rotating filling apparatus for cooperation with controllably actuable members of said filling devices to vary the setting of said filling devices in accordance with the measured control weighings on the rotating transfer apparatus.
A method of automatically controlling an apparatus for filling containers including a plurality of filling stations, each having a controllable filling device, each actuated individually for delivering a metered amount of filling material into continuously successively forwarded containers during a filling cycle, comprising the following steps:
A device for automatically controlling a filling machine comprising at least a rotating filling apparatus having n filling stations, each comprising a controllable individually actuated filling device, a rotating transfer apparatus having n.sub.1 stations for receiving containers which have been filled in said filling apparatus and including n.sub.1 -1 passive container receiving stations and one container receiving control weighing station, a transfer means for taking successively the totality of said containers filled in said rotating filling apparatus and for transferring same to said rotating transfer apparatus, n.sub.1 and n being incommensurable numbers, comparison means associated to said control weighing station of said rotating transfer apparatus, correcting means operatively connected to said comparison means for selectively and individually correcting said filling devices of said filling stations of said rotating filling apparatus, and means for continuously taking said filled containers from said rotating transfer apparatus.
