Abstract
A volumetric filling device which utilizes a pair of connected chambers is selectively filled through a threeway valve with a product. The volume of the lower chamber is adjusted by vertically manipulating a displacement plug in a standpipe extending into the upper chamber. The standpipe extends into the second or upper chamber so that an overflow from the standpipe falls into the bottom portion of the upper chamber. The chamber is pressurized upon the introduction of a product with pressure in the chamber being regulated. If excessive product is introduced, it flows from the bottom chamber through the standpipe into the upper chamber and is returned through a pressure release valve to be recycled. Once a particular pressure in the upper chamber is obtained, air is forced into the upper chamber to evacuate the standpipe and lower chamber through the three-way valve and an outlet to thereby meter a precise quantity of liquid.

9 Claims, 1 Drawing Figure PATENTEU REL BACKGROUND OF THE INVENTION DESCRIPTION OF THE PREFERRED EMBODIMENT In the single view, the filling device of the present in- In the bottling and packaging of liquid products, it is 5 vention is generally indicated by the numeral 10. It is necessary to meter fairly precise quantities of product to comply with most state laws on labeling and packaging a product. Moreover, many problems exist with volumetric devices because of the nature of the product itself. For instance, some liquid products tend to expand when being handled either by dissolving air, by foaming or sudsing. Moreover, liquid products are quite often difficult to dispense from a volumetric device because of dripping or clinging to the side walls of the device. Further, many problems have been encountered in volumetric filling devices through the buildup of sediment or coatings on the surface so that the measured volume will vary through a work day. This typically will happen with paraffin containing liquids.
On occasion, it is necessary to adjust a volumetric filling device from a first desired metered quantity to a second quantity and if this occurs, such adjustment may have to take into account the effects mentioned above which are quite often nonlinear.
In the filling of containers from a volumetric metering device, production is quite often dependent on the speed with which the container is filled. The present in vention provides assistance to filling speed by virtue of the use of pressurized evacuation of the device. This prevents holdover bubbles and side wall deposits which cling and run rather slowly to the bottom. They are forced out at a greater rate of speed through the introduction of a blast of air through the filling chamber. Moreover, the device can be filled rapidly with no problems from overflow. For instance, should the apparatus of the present invention be filled rapidly and cause foam on the top of the liquid, the foam is drained off quickly to permit the subsequent filling of the container through the metering apparatus of the present invention. More will be noted below in summarizing the present invention.
SUMMARY OF THE PRESENT INVENTION The present invention is summarized as comprising a pressure vessel which is divided into a pair of chambers, upper and lower chambers. The lower chamber extends by means of a stand pipe into the upper chamber. A displacement plug is placed in the standpipe to adjust the volume of the lower chamber plus the standpipe diminished by the volume of a displacement plug. This permits fine adjustments on the volume of the lower chamber. A liquid product is introduced into the lower chamber by means of a three-way valve and fills to the top edge of the stand pipe. Foam on the top spills over the side into the second or upper chamber. Liquid product captured in the upper chamber is returned through a pressure release valve and line back to the product source for recycling. Air is introduced in the upper chamber to force the liquid product in the stand pipe and lower chamber through a threeway valve into the container to be filled. Many other details of construction and operation will be described below.
BRIEF DESCRIPTION OF THE DRAWING The single drawing is a sectional view through the apparatus of the present invention showing the liquid metering apparatus of the present invention.
adapted to fill a container of some suitable form and shape indicated by the numeral 11. The liquid product to be placed in the container 11 is of no particular concern except to note that various and sundry liquid products have many different problems. For instance, the products may include food products such as milk or other drinks, cosmetic products such as facial soaps, household products such as kitchen waxes and many others. In any case, the present invention includes a three-way valve 12 which is connected by means of an inlet line 13. The line 13 is adapted to be communicated with a large supply of the product to be placed in the container 11. This may be a tank or vat which supplies the product under pressure. More will be noted concerning this hereinafter. The three-way valve 12 is connected to a downwardly directed spigot 14 which extends into the neck of the container 11 or at least is positioned immediately adjacent to the mouth of the container. Depending on the arrangement of the container 11 with respect to the spigot 14, various and sundry conveyor belts and other transfer systems are utilized to position the container 11 in position below the spigot 14 so that several are filled in succession.
The numeral 15 identifies an upward extending conduit in line with the spigot 14. The conduit 15 is connected to a large closed vessel 16. The vessel 16 is divided into two chambers, the first chamber being that indicated at 17 which will be denoted hereinafter as the lower chamber or the product chamber. The upper chamber is denoted by the numeral 18. A central diaphram l9 divides the vessel 16 into the two chambers. The lower chamber 17 is the chamber for receiving the product which is to be metered. The product is introduced through the conduit 13, the valve 12 and then through the line 15. The product is introduced into the lower chamber 17 and fills the lower chamber to a suitable level. The product is introduced until it fills the lower chamber 17 and also fills a stand pipe which is indicated by the numeral 20. The stand pipe extends toward the top portions of the vessel 16, well above the level of the liquid product overflowing into the upper chamber 18. The stand pipe adds to the volume of the lower chamber in a manner to define a maximum volume which includes the lower chamber 17 and the volume of the stand pipe 20. The stand pipe serves several purposes as will be noted hereinafter.
A displacement plug 22 is inserted into the stand pipe 20 to precisely control the total volume of liquid to be dispensed. Since the maximum is equal to the lower chamber 17 and the stand pipe 20 without the plug, the maximum is diminished to a desired level by lowering the displacement plug 22. When it is lowered to the level of the upper lip of the stand pipe, it begins to reduce the total effective volume of the lower chamber. The displacement plug 22 is preferably mounted on a threaded shaft 23. The threaded shaft connects with a transversely extending support bar 24. Further, a bolt head 25 is carried on the upper end of the threaded shaft 23 to permit ease of manipulation by means of a tool such as a screwdriver or wrench to rotate the shaft 23 and thereby move the displacement plug upwardly or downwardly to finely tune the volume of the lower chamber 17. While other mechanical techniques can be implemented for moving the displacement plug, the apparatus described above is relatively simple and inexpensive in cost.
The displacement plug extends through an opening within the vessel 16. The opening is sealed by means of an O-ring seal 28 which surrounds the displacement plug 22. This prevents the escape of air or product along the displacement plug as it extends upwardly out of the vessel 16.
The vessel 16 is held in a framework which supports the vessel with respect to the container 11 and the feed line 13. While other arrangements can be utilized, the supportive framework includes a generally circular plate 32 at the bottom and a similar plate 33 at the top. A number of tie bars 34 extend betweenthe two plates at spaced locations around the vessel 16. The tie bars 34 are bolted and pulled snug to clamp the vessel firmly between the circular plates 32 and 33. In addition, the tie bars 34 extend upwardly to the transverse member 24 and support it in position over the displacement plug The vessel 16 is actually constructed of two members which are joined together at the central diaphram 19. The diaphram 19 has an outwardly extending flange and O-rings are positioned on the upper and lower faces of the flange. Thus, the external framework holds the two members together and achieves a sealing relationship at the flange such that no leakage occurs along the edge of the diaphram 19.
The upper chamber 18 is drained through a faucet 37. Additionally, a pressure gage 38, if desired, is attached to indicate pressure within the upper chamber.
The upper chamber is connected with a line 40 which communicates through a valve 41 for returning excess product to the supply source. This line is connected just above the divider 19 so that it drains substantially all of the fluid accumulated in the upper chamber 18. A second line 42 is connected to the upper chamber. It is preferably connected with a source of air under pressure, a representative pressure being given hereafter. A valve (not shown) opens the line 42 to deliver air under pressure for evacuation of the lower chamber 17 when the container 11 is actually filled. This will be described in detail hereinafter.
The valve 41 is set to relieve pressure within the upper chamber in a particular manner. This will be described when representative values of various pressures are given hereinafter.
While the foregoing describes the apparatus, an example of operation will be given to further enhance the understanding of the present invention. Assume for sake of discussion that the chamber 17 including the stand pipe to its upper lip holds a volume of 32 fluid ounces. This then defines a structure, depending on the size of the displacement plug, which can dispense from 32 ounces down to approximately 20 ounces depending on the position of the displacement plug. Suppose again for sake of example that the displacement plug is positioned to reduce the lower chamber 17 by 8 ounces so that it holds 24 ounces. Suppose further that the ratio of the lower chamber to the upper chamber is such that the air which is in the lower chamber, when empty, is forced into the upper chamber to achieve an approximate four-fold increase in pressure. This might provide a pressure in the upper chamber when the fluid is introuct is introduced, the valve 12 is turned to close off the chamber 17 prepatory to delivery of the product to the container 11. At this juncture, approximately 2 or 3 ounces has overflowed into the upper chamber 18 while the exact quantity desired, i.e., 24 ounces, is found in the lower chamber 17. Additionally, the pressure in the upper chamber 18 has risen perhaps to about 60 psi.
With the pressure in the upper tank 18 at an elevated level, the three-way valve 12 is simply opened to communicate the lower chamber 17 with the spigot 14. The air in the upper chamber forces the product from the stand pipe and the lower chamber 17 rapidly.
The rush of product is maximum when the valve 12 is first opened. The product quickly fills the container. After the initial surge the flow of product drops. This is quite useful in the filling of a container. The initial surge tends to fill the container quickly at a stage when foaming or sudsing does the least harm. By way of contrast, the last portion of product fills the container at a rate which declines, somewhat exponentially, with less splash and foaming. Since the filling rate drops, the foam in the container has time to disperse and spill over is avoided or eliminated.
The chamber in the device compresses the air by an amount equal to the amount of product introduced into the vessel, and the air is subsequently returned to atmospheric pressure on delivery of the product. The air serves a type of pneumatic spring which stores energy for dispensing the liquid product. The product is delivered with an initial surge and a later decay in flow rate.
Should it be helpful, a short air burst can be delivered and introduced through the line 42 to boost delivery. This is optionally of assistance for some circumstances but is not normally required for most products.
The release valve 41 is set at a desired level to periodically exhaust product overflow in the upper chamber 18. The excess product is returned to the storage tank so that it can be supplied again.
After the device is placed in operation, the dispenser functions time after time without variation in quantity. The repetitive use of the device fills consistently notwithstanding wall cling which adds to each filling, the wall cling of the prior filling. Since this factor is constant, it is of no consequence during continued uses.
The amount of overflow of the lower chamber 17 need not be so great as to fill the upper chamber 18. Preferably, the overflow is held as small as possible, consistent with the speed of operation in filling the lower chamber 17 to the desired level.
The foregoing describes the operation of the preferred embodiment of the present invention. It will be understood that through the sequencing of the product delivery valve and air valve (not shown) that the apparatus can be used to rapidly fill the container 11 and subsequent containers. Preferably, the valve 12 and the other valves are solenoid operated to enhance high speed automatic operation.
In the use of the device, it can be adjusted to dispense a different quantity by adjusting the displacement plug 22. However, it is believed that description of an example of operation is not needed because the foregoing disclosure is amply detailed to set forth the operation of the device after manipulation of the displacement plug to a different position. It is appreciated that the exterior of the displacement plug can be calibrated so that its linear position is related to the actual measure in liquid dispensed by the apparatus 10. Thus, trial and error adjustments to position the displacement plug are not required.
