  • Patent number: 4974755
    Abstract: A dispensing valve assembly and system for viscous materials includes a dispensing valve including a valve casing with an interior chamber, a dispensing port and a longitudinal valve passageway. An inlet port intersects the valve passageay and connects to a source of material to be dispensed. A valve element is slidably received in the passageway and includes a drive shaft portion, an elongated piston head portion and a waisted portion. Seals are provided to seal against the piston head, and the valve element reciprocates over a cycle so that the waisted portion periodically interrupts the first seal allowing material to flow into the chamber and out of the dispensing port. As the valve element closes, a seal is again established to shut off material flow. Continued advancement retracts the piston head further from the chamber to create a negative pressure that draws back material from the dispensing portion to cause a clean cut off of flow. A metering port and a metering cylinder may be employed.

    Abstract: A process and apparatus for drawing off deformable masses containing air, such as sausage masses. The mass is transferred in a stream from a supply space into a filling cylinder where a vacuum is generated relative to the space to remove air from the mass, and the transferred mass is then ejected from the filling cylinder by means of a piston. To transfer the mass quickly and remove air from it completely, the mass stream is guided, during its transfer into the filling cylinder in such a way that, as it enters the filling cylinder, it first moves towards the cylinder wall at an angle to the direction of the piston. Moreover, during filling the level of mass in the filling cylinder is maintained at an essentially constant filling height so that a constant volume of free space remains above the mass in the filling cylinder.

    Abstract: Apparatus for filling containers with two products from different sources, using a rotating volumetric filler which picks up first one product then the other, and discharges them both simultaneously into a container. The filler uses a pair of concentric pistons, the central one of which is retracted to pick up the first product as it rotates over an arcuate slot beneath which the first product is stored; the outer, cylindrical piston is then retracted to pick up the second product as it rotates over another arcuate slot beneath which the second slot is located. Both pistons are later extended simultaneously to discharge the combined product into the container. Since the two products picked up by the successive retractions of the two pistons are held beside each other, a more uniform mixture of the two products is obtained than if they are picked up one above the other by a single piston.

  • Patent number: 4489769
    Abstract: A continuous-cycle filling-machine for aseptic batching comprises a revolving basin whose floor exhibits a plurality of open-topped cylinders communicating therewith and accommodating respective sliding plungers designed to expel contents of the cylinder toward a filler-jig. A fixed obturator is in direct contact with the basin-floor under which the cylinders are brought to bear by rotation of the basin during the delivery-stroke. An annular chamber located externally and beneath the basin communicates with a source of sterilizer fluid by way of a feed-conduit within the shaft around which the basin rotates. An outer-casing has a bottom-face at least part-created by the basin-floor and an interior which receives slightly-pressurized fluid. Sterile conditions are thus maintained within the machine. Lifting gear is provided for raising the obturator from the basin-floor at will.

  • Patent number: 4335760
    Abstract: An apparatus for holding a syringe and filling ampules is described. The apparatus is comprised of a housing having a base and a vertical support member. A syringe holder is affixed to the vertical support member in a manner which permits the syringe holder to slide up and down between two limits on the vertical support member.The apparatus operates by first lowering the syringe holder downward to place the needle of the syringe (in the holder) into an ampule, in response to the downward movement on the device's handle. Further downward movement of the handle causes material from the syringe, such as a viscous liquid, to be dispensed into the ampule.

  • Patent number: 4308900
    Abstract: A container filling system and method is disclosed which includes a filling valve which receives a product through an inlet port in the side of a vertically movable cylinder having a vertically moving plunger therein that opens and closes the port. While the port is open and product is metered into the pouch, steam is directed through the filling valve to purge air from the product and from the pouch and to clean the product from the plunger. The system also includes pouch spreading fingers which leads the filling valve cylinder into the pouch to assure proper opening of the pouch. A dynamic parallelogram linkage is provided to move the filling valve and finger operating mechanisms vertically as a unit and includes resilient means which raises the filling valve above the top of the pouch in the event the power means which actuates the linkage fails.

  • Patent number: 4300603
    Abstract: This device for rapid and extremely accurate filling of containers includes a duct for bleeding off gas bubbles from a metering device, where prior bubble-eliminating provisions are inadequate due to extreme product viscosity. The device also has relative adjustment between a positive mechanical stop, used to define very precisely the substance volume metered by a biacting piston, and a control switch used to reverse the piston. This adjustability corrects an inaccuracy arising in prior devices due to the necessarily slower speed of the piston with extremely viscous product.

    Abstract: Product is delivered into a funnel which then is moved downwardly to deposit the product into a pouch. The funnel includes a movable plate which initially is disposed in a closed position to enable the funnel to receive and retain the product. As the funnel travels downwardly, the plate moves to an open position to enable the product to be delivered out of the funnel and into the pouch. When the plate moves to its open position, the interior of the funnel takes on the same shape as a plunger which moves downwardly through the funnel to force the product out of the funnel.
