ABSTRACT:
A rotary filling machine having a rotating platform with stations on which bottles are supported for filling with liquid dispensed through filling head assemblies at each individual station. A master electronic circuit mounted on the rotating platform is connected to separate station electronic circuits for distribution of selected electronic signals received from a non-traveling, settable circuit. Each electronic circuit compares the signal corresponding to the sensed extent of fill determined by a sheer beam strain gauge load cell at each station and provides an electrical signal to the valve control in response to the comparison to cause the valve to close to stop filling the container at the station. The fill is, thereby, stopped immediately and accurately in response to the sensing to the sensing andin comparison with a set fill extent, with each station being controlled separately without dependence on or delay resulting from operation or sensing by the controls at other stations, with the electronic controls being isolated from any extraneous effects of crossing moving
on-moving interfaces, and being capable of individual intelligence determinations for control and compensating adjustment of filling operations as they are taking place as well as for subsequent filling operations at the same station during subsequent cycles.
