- The present invention relates to a valve assembly for rapidly filling containers with metered quantities of materials. More specifically, the valve assembly of the present invention is provided for filling containers, such as flexible packages, with beverages.
- 2. Description of Related Art
- Various systems are known for filling containers, such as flexible packages, with beverages or particulate material. These systems use various types of valves, which have internal actuators for the valve elements. These actuators may be pneumatic or electrical, as desired.
- However, these known valve assemblies with internal actuators present various problems. First of all, the internal actuators make it difficult to clean the interior of the valve assemblies, especially when a syrupy beverage or a citrus juice is being dispensed. Furthermore, the internal valve actuators are generally not as durable as needed, and are difficult to repair, since the entire valve must be disassembled to make such repairs.
- Accordingly, there is a need in the art in filling machines for containers for durable valve assemblies which are easy to repair and easy to clean.
- Accordingly, it is a primary aspect of the present invention to provide a valve assembly for use in rapidly filling containers with liquids, such as beverages, particulate materials, or the like which is durable, easy to repair, and easy to clean.
- These aspects of the present invention are fulfilled by providing a valve assembly for filling containers with metered quantities of material comprising: a frame for supporting the valve assembly; a housing defining a valve body, and a chamber therein, said chamber having open top and bottom ends, substantially, and smooth interior sidewalls, said valve body having an openable bottom end in a lower portion thereof; a valve element for opening and closing the openable bottom end for accommodating or blocking, respectively, the flow of the materials through the openable bottom end; and an actuator device for imparting relative movement between the valve element and the openable bottom end to achieve open and closed positions thereof, said actuator device being disposed outside of said valve body and out of contact with materials therein.
- The valve assembly includes a bracket supporting the valve body, and an annular bracket around a movable portion of the valve body for supporting the actuator device and operating the valve.
- The chamber within the valve assembly is preferably an open-top chamber with a funnel-shape for containing the materials to be dispensed from the valve assembly. The open top is connectable to a filling conduit.
- A disc is disposed in space relation to the bottom openable end of the chamber, and has a central bore for fixedly supporting a central pin extending from the valve element. Flow ports are provided in the disc surrounding the central aperture for accommodating liquid or material flow therethrough.
- In a preferred embodiment of the present invention, the actuator device comprises an air cylinder assembly. The lower section of the valve body is provided with a concentric sleeve telescopically disposed on the main portion of the valve body, and pistons thereof are mechanically linked to the annular bracket secured to the lower portion of the valve body. Preferably, a pair of air cylinders is provided, which are symmetrically disposed on the support bracket about the valve body.
- The valve assembly of the present invention, and its preferred use, is included within supply conduits of a filler unit disposed in an assembly line for rapidly filling a succession of containers, such as flexible packages.

- FIG. 4 is a top plan view of the valve assembly of FIG. 3.
- Referring in detail to the drawings, an exemplary method and system for rapidly filling flexible pouches with hot beverages is generally illustrated in FIG. 1. A
juice pasteurization device 10 is provided for heating juice concentrate to a temperature high enough to pasteurize the concentrate and deliver it to arotary filling station 12. The juice concentrate may vary in composition. For example, it may be a flavor concentrate combined with sugar, or may be a natural juice concentrate such as orange juice, which is used to form the final consumable beverage by mixing with a liquid such as water. - In accordance with the present invention, the flexible packages to be filled are formed in a pouch-forming machine14, which may be any commercially available type of machine providing a pouch output of approximately 600 ppm. The pouches formed before sealing are filled with hot liquid, such as pasteurized juice. The hot juice dispensed from
juice pasteurization device 10 enters the filling machine and the pouches. - Preferably, the pouch forming machine14 receives a folded sheet of a plastic web from roll stock
pouch forming machine 16, and divides sections of the web into individual flexible pouches for filling from theliquid filling machine 13. Preferably, the pouch forming machine, in conjunction with thefilling machine 13, can make and form filled packages rapidly on a continuous basis at a rate of about 600 ppm for 200 ml pouches, or 300 ppm for 330 ml pouches of various desired shapes and characteristics. - The pouches, once filled, are sealed along the fill opening thereof by a continuous
sonic sealing device 20. Drinking straws may be inserted into the pouches, or attached thereto through the use of a known type ofstraw application device 22. Pouches from the roll stock are separated into individual containers through the use of a die-cutting device 34, which may also be provided with a printer for coding the packages with information such as the date of manufacture. Also provided at the output of the package forming and filling machinery is a rotary discproduct transfer device 24 which supplies individual packages to a conveyor 27 for passing through a pouchweight checking device 26, which determines if the pouch has been properly filled. The pouches then move through a helix surge device 29 to aconveyor system 30. A high-speed pick-and-place robot 32 transfers packages from theconveyor 30. - Referring in detail to FIGS.2 to 4, there is depicted a valve assembly in accordance with the present invention. The
valve body 2 includes a funnel-shaped main portion defining aninterior chamber 2A therein. Around the top periphery of thevalve body 2 is a connectingflange 1, which is adaptable for connection to a sanitary connector of a filling unit, such asunit 13 in FIG. 1.Mounting brackets 4 are welded or suitably secured to the outside ofmain valve body 2 for supporting a pair of symmetrically disposedair actuator cylinders 10. An annular mounting plate 3 is provided just abovebottom end 5 ofvalve body 2, and is connected to aconcentric sleeve 11, a lower valve body portion telescopically disposed on the bottom portion of themain valve body 2. A valve element, orplug 8, is disposed within thelower portion 11 of the valve assembly for reciprocating movement therein on apin 8A in acentral opening 12A indisc 12.Disc 12 hasflow ports 12B surroundingcentral aperture 12A. Thevalve element 8 opens or closes the discharge opening 11A in response to actuation ofair cylinders 10 andmovable piston rods 10A secured to mountingplate 6. Aviton seal 9 is provided betweenbody 2 andsleeve 11. - In operation, the
valve body 1 is normally full with the material to be dispensed. When it is required to dispense a metered quantity of the material into a container passing by from a conveyor, theair cylinders 10 are actuated to slideconcentric sleeve 11 vertically downward, as illustrated in FIG. 3, to thereby unplug opening 11A withvalve element 8. During dispensing of a metered quantity, theplug 8 is out of contact with opening 11A, andsleeve 11 is in its lower position. The metered quantity of material to be dispensed is controlled by the time that discharge opening 11A is open and the hydrostatic head pressure of the material invalve body 1. To quickly stop flow of material through opening 11A,air cylinders 10retract piston rods 10A, pullingplug 8 into sealing engagement with opening 11A. - Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein.
