A high-speed filling machine for filling a fluid product into small containers, in which a continuously moving conveyor belt brings empty containers to their filling position underneath filling nozzles, where the empty containers are held stationary by an indexing mechanism while the filling nozzles are lowered into the empty containers, the fluid product is discharged into the containers and upon completion of discharge stroke of the filling units, the nozzles are again raised whereafter the indexing mechanism will release the filled containers for further movement by the conveyor belt; the single channel from the inlet end thereby branches out into two parallel channels upstream of the filling station, each provided with its own indexing mechanism, while a nozzle support structure which raises and lowers the filling nozzles into the containers, is also adapted to reciprocate so that alternately the empty containers in one channel and then in the other channel are filled.

141284

A safety mechanism for high-speed filling machines preventing accidental spilling in case of misalignment between a nozzle and the container into which it is to be lowered during filling; a safety arm which normally closes a switch is displaced by a nozzle in case the latter encounters an obstruction and moves relative to its nozzle holder after overcoming the restraining force of a releasable detent mechanism to thereby open the switch and therewith stop the filling operation.

A volume control for a multi-nozzle rotary pump filling system in which a plurality of rotary pumps are driven from a common drive. Each pump is connected with its own nozzle by way of a connection that includes a volume control operable to adjust the back pressure on the rotary pump to thereby vary the amount of product dispensed by the nozzle. In case of more viscous products, a by-pass line which includes a relief valve is also provided between the inlet side of the control unit and the in-feed side of the pump.

A spool-type valve system for use with a high-speed filling machine, in which a solenoid valve controlled by the main shaft of the filling machine, selectively supplies air under pressure to a respective end of a pneumatically operated piston-cylinder unit of a spool valve assembly which selectively opens and closes the pump space with respect to the reservoir for the product to be filled while simultaneously closing and opening the pump space with respect to the discharge nozzle.

141129

A filling machine for filling several containers with predetermined amounts of a product in which the several filling units are actuated by a common driving member; the common driving member itself is actuated by two eccentric drive mechanisms each including a volume-changing adjusting mechanism of the lead screw type; the eccentric drive mechanisms are adapted to be stopped in a predetermined position by a volume-changing stoppage device to enable the installation of an interconnecting member between the two volume-changing adjusting mechanisms to assure identical adjustments.

An indexing system for filling machines used to fill small containers transported on an endless conveyor belt, which includes a container-driven star-wheel, a member preventing the free rotation of the star-wheel and a cam-operated control for enabling and disabling the free, container-driven rotation of the star-wheel.

222267

A fine adjusting mechanism for a number of individual filling units of a high-speed filling machine, operated in tandem from a common drive, which provides an adjustable lost motion between a common drive bar and the pivotal connection with the piston rod of a respective filling unit; the lost motion is adjustable by screwing an adjusting member more or less into the path of the sliding movements of a bearing member sliding in an elongated slot of a swivel member.
