  • Patent number: 5285828
    Abstract: An apparatus for introducing filler material in a fluid carrier into a measuring chamber in rapid succession is described. The apparatus includes a delivery subsystem for introducing the filler material into the fluid carrier. The delivery subsystem provides the fluid carrier and filler material to a diverter subsystem which separates the stream into two separate streams. The two separate streams are directed into a rotating concentrator subsystem that separates the fluid carrier from the filler material and compresses the filler material. The filler material is further compressed and dewatered in a taper subsystem and drain subsystem. The filler material is then dispensed from the drain subsystem into a measuring chamber where it is cut by a knife plate that includes two blades with overlapping cuts. The apparatus is capable of introducing controlled weights or volumes of filler material into a measuring chamber at high speeds.

  • Patent number: 5282500
    Abstract: A container filling apparatus makes it possible to discharge liquid stagnating within a filling valve. The filling valve is lowered towards a container being conveyed. Then a liquid passageway gating section is opened by pressing a bell-shaped member of the filling valve against the container, and liquid thus fills the container. The net amount of the contents to fill the container can be adjusted by vertically moving at least one of a filler liquid tank and a stopper member which limits the lower position of an intermediate spring bracket supporting a second elastic body for biasing a valve body upwardly with respect to a loading table on which the containers are supported. In addition, it is possible to open the liquid passageway gating section by lowering the filling valve with an external force. Therefore, liquid stagnating in the passageway of the filling valve can be discharged.

  • Patent number: 4838326
    Abstract: Apparatus for filling containers from individual volumetric dispensers as both move rapidly along a straight-line path. The dispensers are moved in a closed loop and filled while travelling along another straight-line path opposite the dispensing straight-line path, by forcing flowable product upwardly into the open lower ends of the dispensers as they slide over a filler slot. To prevent flow of the product upward between the dispensers, a mechanism is provided which automatically locks the ends of the adjacent dispensers against each other to provide a seal against inter-dispenser product flow, and which automatically decouples the containers after their filling so they can turn with respect to each other, as is necessary as they negotiate curves in the closed-loop path along which they travel.

  • Patent number: 4817683
    Abstract: Containers are filled with flowable substances while passing through a filling station. The plurality of nozzles and cylinders move through the filling station in unison with the containers. The cylinders have a free flowing piston movable under fluid action alternately to charge and discharge from alternate ends. A spool valve operates with respective cylinders under mechanical activation to charge and discharge cylinders and permit fluid from the supply to feed the respective nozzle. One cylinder end receives a stop rod which can be variably located into the cylinder and thereby to adjust the cylinder volume. The rod can be adjusted precisely as the vertical location of a mounting plate varies, which can be effected during operation of the filling machine. The cylinder length to diameter is substantially elongated to make for precision adjustments of cylinder volume as the rod is located variably into and from the cylinder. A highly precise adjustable filling system is achieved.

  • Patent number: 4789013
    Abstract: A container filling machine has a rotor which is adjustable in height and supports components for filling containers. A carrier support is mounted to support devices which are adjustable vertically on stationary columns. Interlock elements which are arranged radially on the rotor are operable to unlatch the support devices at a specific rotational position of the rotor and to support the support devices and carrier. The lever-shaped latch element of each support device projects into a recess for the interlock element in such a way that with a partial penetration of the interlock element into the support device the support device is still latched to the column but supported and further penetration of said interlock element results in the support device being unlatched so that when the height of the rotor is altered, the support devices and carrier are altered in height correspondingly.

  • Patent number: 4635688
    Abstract: Each filling station comprises a balance (36) and a piston and cylinder volumetric dispenser (37). The piston rod (33) is actuated by a cam (34) which optionally includes a portion (341) which is adjustable. Resilient means (40) are interposed between the cam and the piston. While a receptacle (39) is engaged in a filling station the following operations take place in succession: the empty receptacle is weighed and at the same time the volumetric dispenser is filled with slightly more material than is to be dispensed; the material in the volumetric dispenser (37) is then transferred to the receptacle (39) and the receptacle is continuously weighed until it has received the set weight of material. The outlet from the dispenser is then closed, thus jamming its piston before it reaches the end of its stroke. The resulting forces are absorbed by the resilient means.
