PATENTEUFEB 9 ISH INVENTOR. Bernhard Ragga LIQUID FILLING HEAD ,DEDICATORY CLAUSE The invention described herein may be manufactured, used, and licensed by or for the Government for governmental purposes without the payment to me of any royalty thereon.
My invention relates to an apparatus, system, and method for rapidly filling containers with liquid material which is highly toxic.
While filling devices have been disclosed in the prior art, these all presented certain disadvantages and problems. For example, the prior art devices required the container to have a strippable plastic coating to utilize the device; or the container required a decontamination washdown following filling due to overflow; or dripping or work surfaces became contaminated due to container overflow; or complicated weighing, volumetric measurement, and timing techniques were required to be employed in conjunction with the prior art filling device; or the container to be filled left the filling station in a partially or unfilled condition or containing a quantity of foam. My invention was conceived and reduced to practice to overcome and solve these disadvantages and problems.
A principal object of my invention is to provide a reliable apparatus system, and method for rapidly andcompletely filling containers with toxic liquid material and eliminating partially or unfilled containers from leaving the filling station.
Another object of my invention is to provide a reliable apparatus, system, and method for rapidly and completely filling containers with toxic liquid material without fonning foam within the container or filling apparatus. This object is impor tant, because it is desired to fill the container with liquid and not foam.
A further object of my invention is to provide a reliable apparatus, system, and method for rapidly and completely filling containers with toxic liquid material to a constant filling height irrespective of the container size without utilizing complicated weighing, volumetric measurement, and/or timing techniques.
Still another object of my invention is to provide a reliable apparatus, system, and method for rapidly and completely filling containers with toxic liquid material which prevents overflow of the container; avoids container, work surface, and
filling apparatus contamination, and eliminates decontamina- I tion washdown procedure.
A still further object of my invention is to provide a reliable apparatus, system, and method for rapidly and completely filling containers with toxic liquid material which eliminates any type of pretreatment of the container to be filled.
Other objects of my invention will be obvious or will appear from the specification hereinafter set forth.
FIG. 1 is a sectional view of my filling head apparatus within the container to be filled.
FIG. 2 is a schematic diagram of my filling system.
FIG. 3 is a .view showing a rotatable table for placing containers in a position to be filled by my apparatus.
'My invention as shown in FIGS. 1 and 2 will now be described in detail as follows.
Container 2 is moved into the filling position by any conventional means 56 shown in FIG. 3, such as the conventional conveyor belt or rotating tabletop feed such as table 2 in FIG. 1 of US. Pat. No. 2,377,796. The movement of containers into filling position as well as all sequencing steps in the filling procedure is controlled by a conventional electronic sequencing unit 22 as shown in FIG.,2. The sequencing unit circuitry comprises a power supply, timing circuits, and control relays such as disclosed in FIGS. 7-9 of US. Pat. No. 2,377,796. When container 2 is brought into the filling position as described above, the container closes microswitch 23, which is conventionally electrically connected in series with conventional solenoid 24. Upon closing switch 23, solenoid 24 is activated which in turn activates the conventional four-way valve 25, which may be either an electropneumatic valve or a hydraulic valve. Activation of valve 25 permits air (TH SOURCE NOT SHOWN IN THE DRAWlNG) to flow in ill 30 and causes my filling apparatus to be lowered by means cylinder 54 connected to filling head rod 1 into the filling por tion until needle 12 is located within container 2 and in scalin engagement with the container by means of O-ring 3, as show in FIG. 1. When the proper filling position is lCflChCt microswitch 26 electrically connected in series with valve 2. opens the electrical circuit and stops the filling apparatus ii the proper position. Simultaneously with the activation v switch 26, microswitch 27, electrically connected in seric with conventional solenoid 28, closes the circuit to solcnoi 28 and causes the solenoid to be activated. Solenoid 28, i turn, activates the conventional three-way valve 29 in tr manner described above regarding valve 25. Valve 29 can t an electropneumatic or hydraulic valve. Simultaneously wii the activation of switch 27, air is evacuated from container by means of a vacuum line (not shown in the drawing) co nected to port 4 in the conventional manner. Activation valve 29 causes air to flow in line 31 (the source of air n shown in the drawing) and to energize spring-loaded cylind 6 through line 7. Energizing the cylinder causes valve 5 move upward and permit ball closure 8 housed in chamb means 55, to be moved into sealing engagement with O-ring by means of spring activator 18. The timing sequence in pan 22 then activates pump 32 which raises liquid to be filled container 2 from reservoir 33 through line 34 to inlet 35. Tl liquid then flows through chambers 36, 37, and 38 into co tainer 2. Foaming within container 2 is avoided by means the centrifugal force induced to the liquid in chamber 38 l means of helix 11 located wiihin the chamber, which enablthe liquid to drain down chamber 38 walls rather than dl't straight into the chamber. A further aid in eliminating foamii is the parabolic curvature of the upper surface of point 39 needle 12, which imparts an umbrclla-shaped curtain of liqu with a clear center. The liquid level continues to rise in c0 tainer 2 until the bottom of point 39 is reached. After reachi point 39, a stream of liquid is pulled up tube 15 of needle by means of vacuum applied to ports 13 and 14 in the conve tional manner. Liquid flows from tube 15 into chamber which is provided with baffle 19, the baffle being incorporat' to avoid giving false signals to electrodes 17 due to splashin When the liquid level rises to electrodes 17 in chamber 16, tl liquid acting as an electrolyte, an electrical circuit completed to microswitch 41 which activates solenoid 28 close valve 29 by means of conventional spring retu mechanism 42; the circuit to microswitch 41 being completi through conductors 57 which are connected to electrodes in the conventional manner. Closing of valve 29 interrupts a flow to cylinder 6 which causes valve 5 to close in sealing c gagement with chamber 36 by means of O-ring 43 and to i terrupt liquid flow to the container. Excess liquid in chambt 36 and 37 is drained back to reservoir 33 by means of out 10. Positive drain back from chamber 37 is insured chamber 37 being installed at an angle of approximately from the horizontal measured in a counterclockwise directio Valve 5 is designed in a T configuration and fits snugly chamber 36 as a safety feature to avoid liquid leakage shou O-ring seals 43 fail. The filling apparatus is then partia' raised, by means of control panel 22, so that point 39 is abo the liquid level within the container but still within the cc tainer. In such a raised position, excess liquid is drained frt tube 15 and chamber 16 by means of vacuum to reservoir through lines 45 and 46. The vacuum system is then st down, the filling apparatus returned to its starting position, t filled container moved from thefilling position to a ClOSl position, and the procedure as described above cyclically 1 peated. Since filling is accomplished by subjecting the cr tainer to vacuum, toxic Iiquids having a low vapor pressu would partially vaporize and condense at fill opening 44. order to avoid such condensation, an annular groove 20 is pr vided in needle housing 47 with sleeve 21 extending from t groove to vacuum port 4. Such means prevents any liquid vapor extending above groove 20 during the vacuum cycle. Pump 48 is provided to add make-up liquid to the system from a source not shown in the drawing. Pressure within the system is monitored by gauges 49, and liquid amount within the system is monitored by gauge 50. Valves 51 are provided for periodic maintenance, adding make-up liquid, draining liquid from the system, and relieving pressure buildup within the system as required in the conventional manner. All liquid feed lines as required in the conventional manner. All liquid feed lines are conventional flexible tubing such as Tygon. The return of the filling apparatus to its starting position is accomplished by activating spring return mechanism 52 through solenoid 24 which interrupts the airflow through line 30 and exhausts the air through line 53, The conventional timing circuits utilized with my apparatus are correlated to insure proper sequencing of events so that each step is carried out as described above.
lt is obvious that other modifications can be made of my invention, and l desire my invention to be limited only by the scope of the appended claims.
