Definitions

  • This invention relates to a filler valve assembly forfilling containers with liquid products, said filler valve assembly comprising an upper body, a main body, a pressure-responsive assembly mounted so as to separate said upper and main bodies, spring means cooperating with the pressure-responsive assembly and mounted between the pressure-responsive assembly and the upper end of said upper body, an inlet connection connected to an opening in the side of the main body; nozzle means connected to the lower end of said main body, a valve connected by rod means to said pressure-responsive assembly, a valve seat formed so as to cooperate with the valve and orifice means including a cylindrical surface formed in said main body for a predetermined height the adjacent valve member secured to said rod means accommodating the flow therepast of a selected volume of fluid products.
  • this invention relates to filler valves for liquids and, more particularly, to a diaphragm actuated filling valve including a sleeve nozzle which is adaptable to being inserted into a container to fill the container with a liquid as the container and sleeve nozzle are separated from one another at a predetermined rate.
  • container filler mechanisms have generally included nozzle means disposed above an open-top container which drop the liquid product the full depth of the container, resulting in the formation of foam when the container is full, which tends to interfere with the top sealing operation.
  • filler units are adapted to either being inserted into a container or to having a container fitted around the filler unit in order to progressively fill the container as the filler unit is removed relative thereto, thereby tending to minimize the formation of foam.
  • bottom up filler valves Such filler units will be referred to as "bottom up" filler valves.
  • a filler valve assembly of the type described at the outset is known from DE-A-23 58 157.
  • the pressure responsive assembly is quite complicated and comprises two separate diaphragms being arranged at the top of the main body and in the upper body, respectively. Further, in the known valve assembly a pressure fluid acting upon the upper one of the two diaphragms is needed for actuating the valve and orifice means, respectively.
  • a dish is lowered to open an annular part between two chambers for the passage of the fluid to be dispensed through a nozzle and a valve when the pressure of the incoming fluid overcomes the back pressure of a spring.
  • the dish merely serves as an opening and closing valve there being no variable orifice means operable depending on the pressure of the fluid to be dispensed.
  • a general object of the invention is to provide an improved bottom-up type filler valve.
  • Another object of the invention is to provide a diaphragm actuated, bottom-up filler valve.
  • a further object of the invention is to provide a diaphragm actuated, bottom-up filler valve including interchangeable sleeve nozzles suitable, respectively, for milk or clear juice products and buttermilk or pulpy products such as orange juice.
  • a filler valve assembly of the type indicated at the outset and being characterized according to the second-part of claim 1 in that said orifice means includes a frustoconical surface formed just above the cylindrical surface for a second predetermined height for cooperation with the adjacent valve member to accommodate the flow therepast of a larger selected volume of fluid products than that which occurs between the cylindrical surface and the adjacent valve member; in that said nozzle means is a sleeve nozzle and in that said pressure responsive assembly is designed so as to be urged upwardly by the pressure of said liquid products.
  • Figure 1 illustrates a filler valve assembly 10 including a main body section 12, an upper section 14 and a lower section 16.
  • the main body section 12 includes a cylindrical housing 18 having an inlet connection 20 formed in a side wall adjacent the upper end thereof.
  • a frusto-conically shaped seat 22 is formed on the inner lower portion of the body section 12 just below an orifice area consisting of a substantially cylindrical surface 23a adjacent the seat 22, and a steeper frusto-conical surface 23b above the surface 23a, for a purpose to be described.
  • a valve member 24 having a frusto-conically shaped peripheral edge is mounted on a valve rod 26 for axial movement within the body section 12.
  • a guide member 28 is formed on the valve rod 26 for cooperation with the housing 18 to retain the valve rod in axial alignment in the section 12 such that, when closed, the valve member 24 engages the seat 22 in a sealing relationship.
  • a lightweight diaphragm 30 preferably formed of a suitable fabric material covered with a rubber compound, such as silicon, is confined at its peripheral edge between the upper and main body sections 14 and 12, respectively.
  • the upper end of the valve rod 26 extends through an opening 32 formed in the center of the diaphragm 30.
  • the latter is confined between a retainer flange 34 formed on the valve rod 26 and a centrally perforated cup-shaped piston member 36 secured around the valve rod and against the diaphragm 30 by a locknut 38.
  • a vent hole 39 is formed in a wall of the upper body section 14.
  • a spring 40 is mounted between the member 36 and an end wall 41 of the upper body section 14. If desired for particular products, a pneumatic or other type pressure means may be used in lieu of, or in addition to, the spring 40 to assure faster response time.
  • lower body section 16 Three types are interchangeably connected to the housing 18 of the main body section 12 via a suitable snap-on pin and groove or bayonet-type connection 42.
  • An "O" ring seal 44 is mounted between the lower and main body sections in a groove 45 formed in the main body section.
  • a diffuser 50 is removeably mounted on the inner surface of the flange 48 and retained there against by a spring 52 mounted between the diffuser and the lower edge of the main body section 12. This sleeve nozzle 16a is preferred for use with regular milk and clear juices.
  • the diffuser 50 may consist of a screen pack including a plurality of openings (not shown) small enough to hold liquid thereabove by virtue of capillary action until such time as a pressure is directed to the liquid. It should be noted that a sleeve nozzle of the type described is adaptable to the above referenced bottom-up type filling arrangements for containers, such as that represented at 53 and shown surrounding the sleeve nozzle 16b in Fig. 2.
  • the second type of lower body section 16 which shall hereinafter be referred to as sleeve nozzle 16b, shown in Figure 2, includes an outlet opening 54 defined by an internally tapered flange 56 formed at the lower end thereof.
  • a conically shaped enlargement 57 formed on the lower end of a rod 58 terminates in a cylindrical lip seal surface 60.
  • the rod 58 includes a flat extension 62 at its upper end adapted to being mounted in a slot 64 formed in the end of the upper valve rod 26 by a pin 66 extended through aligned openings 68 and 70 formed in the respective rods 26 and 58.
  • a guide member 72 is formed on the rod 58 for cooperation with the wall of the lower section 16 such that the lip seal surface 60 is aligned so as to fit just inside the outlet opening 54 in a capillary seal relationship therewith.
  • a spherical extension 74 is formed on the outer face of the lip seal surface 60 to aid in shaping the liquid flow pattern when the lip seal surface 60 is open with respect to the opening 54.
  • the sleeve nozzle 16b is preferred for use with heavy and pulpy products, such as buttermilk and orange juice.
  • the third type of lower body section 16, which shall hereinafter be referred to as sleeve nozzle 16c, shown in Figure 3, includes a valve 76 formed on the end of the rod 58 and which cooperates with a seat 78 formed at the lower end of the sleeve nozzle.
  • the valve 76/78 when the valve 76/78 is-closed, the upper valve 22/24 is open, serving as an orifice.
  • the spherical extension 74 now serves as the sealing surface in addition to shaping the liquid flow pattern.
  • valve assembly 10 is first primed such that the main body 12 and the lower nozzle section 16 are filled with a selected liquid product.
  • the assembly is then ready for a production run, whereupon a measured volume of fluid product is communicated from a tank (not shown) via a timed piston or other suitable arrangement (not shown) to the inlet connection 20 and, thence, into the main body section 12.
  • a measured volume of fluid product is communicated from a tank (not shown) via a timed piston or other suitable arrangement (not shown) to the inlet connection 20 and, thence, into the main body section 12.
  • the assembly consisting of the diaphragm 30, the retainer flange 34 and the piston member 36 are urged upwardly against the force of the spring 40, the air therein being purged through the vent hole 39.
  • valve member 24 This causes the valve member 24 to be lifted from the - seat 22, within the orifice surface 23a for small volumes, such as about 0.25 I (half pints), or upwardly within the orifice surface 23b for larger volumes, such as about 0.5 or 1 I (pints or quarts).
  • This causes the incoming product to be directed through the valve area 22/24, thereby urging an equivalent measured volume of fluid which was confined in the lower and main body to be urged through the diffuser 50 sections 16 and 12 into a selected size container positioned therebelow by the usual indexing conveyor (not shown).
  • Conventional external means may be employed to raise and lower the container 53 relative to the sleeve nozzle 16.
  • the spring 40 urges the diaphragm 30 and, hence, the valve 24 downwardly until the latter once again is seated on the seat 22.
  • the incoming liquid replaces the volume of liquid in the main and lower body section 12 and 16, ready for the next cycle.
  • a fluid product is contained in the main body 12 and between the valve member 24 and the lower lip seal surface 60 of the sleeve nozzle 16b as a result of the capillary seal effect between the lip seal surface 60 and the adjacent opening 54.
  • the operation is the same as described above relative to the sleeve nozzle 16a once a timed pulse of liquid is communicated through the inlet connection 20.
  • the main body section 12 includes the frusto-conically shaped valve 24 and the valve rod 26 as in the Figure 1 arrangement, and a valve seat 22 which differs from the valve seat 22 of Fig. 1 in that the frusto-conical surface thereof extends into the wall of the main body housing 18 to blend into an annular groove 82 forming an annular cavity in the wall of the housing intermediate the seat 22 and the cylindrical surface 23a.
  • a valve seat 22 which differs from the valve seat 22 of Fig. 1 in that the frusto-conical surface thereof extends into the wall of the main body housing 18 to blend into an annular groove 82 forming an annular cavity in the wall of the housing intermediate the seat 22 and the cylindrical surface 23a.
  • An advantage resulting from having the annular cavity 82 is that the vertical travel distance of the valve 24 and valve rod 26 is substantially reduced, thereby resulting in the valve 24 being more responsive for both its closing and opening functions, the closing action functioning on the order of a "sink stopper" effect, i.e., the suction and/or inertial effects of the moving liquid serving to speed up the closing.
  • An additional advantage is minimizing wear of the diaphragm due to the reduced flexing thereof.
  • the invention provides a versatile filler valve arrangement for various liquid products, as well as for various size containers, and one which is highly efficient in operation so as to be capable of meeting the fast production requirements of today's conventional forming, filling and sealing machines.
