Definitions

  • ABSTRACT A system for handling and distributing fluid is disclosed, which system is particularly useful for handling and distributing coating materials utilized in applying a thin metallic oxide coating to the outer surface of glass containers.
  • the system includes readily accessible and replaceable bulk storage, preferably including a plurality of receptacles such as storage barrels, which receptacles are caused to selectively and sue, cessively supply fluid (which fluid may be chemicals such as titanium tetrachloride, tetraisopropyl titanate, or tin tetrachloride, for example, where a metallic oxide coating is to be applied to a newly formed glass container) to a reservoir which in turn has the fluid pumped therefrom and supplied to a remotely located master tank.
  • the master tank is connected to the reservoir in a manner to maintain a substantially constant fluid level therein, and level monitoring apparatus is provided in the master tank.
  • One or more slave tanks are connected with the master tank and each is maintained at a predetermined fluid level with respect to the master tank.
  • Each slave tank is preferably adjacent to and is connected with a utilization station, which station is an article coating station where newly formed glassware is to be coated with athin metallic oxide coating.
  • the system is automatic in normal operation and indications of deviations in fluid level of the master tank beyond both predetermined minimum and maximum levels are provided by the monitoring apparatus and normal operation is then terminated.
  • the present invention relates generally to a fluid handling and distributing system and more particularly to a system for handling and distributing coating materials used in applying a thin metallic oxide coating to the outer surface of glass articles.
  • such a fluid normally comprises a gas inert to the coating material, such as dry air, and a heat decomposable metallic compound, which may be formed by injecting dry air into the bottom portion of a tank containing the coating material and allowing the air to pass upwardly through the coating material.
  • a vapor including the coating material is expelled from the tank under pressure and introduced into the article coating station, commonly a hood or other enclosure, and articles to be coated are then passed through the hood.
  • Treatment of glass articles to coat the same by introducing a vapor into a hood is shown, for example, in U. S. Pat. No. 3,615,327, while the formation of a vapor that includes a metallic coating compound as coating material is shown, for example, in U. S. Pat. Nos. 3,561,940 and 3,516,811.
  • a closed system is important since, as brought out in U. S. Pat. No. 3,615,327, at least some ofthe me tallic vapors utilized (and hence presumably the coating materials) are stated to be corrosive in nature, and, moreover, each opening of the system (as necessary for replenishing of coating material) can allow entrance of unwanted moisture.
  • Level maintenance of coating material in the tank is also important since the level of coating material will, at least in part, determine the amount of coating material included in the resulting vapor produced where such a vapor is produced by passing the inert gas upwardly through the liquid coating material.
  • This invention provides a closed system for handling and distributing fluids that is simple and inexpensive, yet is dependable, and provides both level maintenance and automatic fluid supply, as well as automatic level monitoring.
  • Another object of this invention is to provide a system that is suitable for automatically providing coating material in liquid form to one or more article coating stations from a supply source that may be remotely situated for convenience.
  • FIG. 1 is a flow diagram, in blockform, of the system of this invention showing utilization at a plurality of ar-.
  • FIG. 5 is a side view of a level control that may be utilized in the master tank of the system of this invention.
  • FIG. 6 is an electrical schematic diagram of the control circuit of the system of this invention.
  • the numerals 11 and 12 in FIGS. 1 through 4 refer to the fluid bulk, or coating material supply source, which is shown in FIGS. 2 and 3 to consist of a plurality (two as shown) of barrels, or drums, of coating material.
  • the coating material when utilized for applying a coating to the surface of glass articles is normally a heat decomposable metallic compound in liquid form, such as, for example, titanium tetrachloride, tetraisopropyl titanate, or tin tetrachloride, all of which are commercially available.
  • the coating material receptacles 11 and 12 are connected by lines, or conduits, 14 and 15, respectively, to
  • Reservoir 17 is, in turn; connected through line 18 to an electric pump 20, which pump pumps coating material through line 21 to master, or main, tank 23.
  • Master tank 23 has a level indicator 24 therein, the electrical leads from which are conducted through conduit 25 to alarm circuitry 27 which has connected therewith alarm indicator 28.
  • This apparatus monitors the level in the tank and indicates any level deviation beyond a predetermined maximum or minimum level.
  • Master tank 23 has connected therewith through a line 30, one or more slave tanks, indicated in FIG. I as a plurality of four slave tanks 32, 33, 34, and 35. As shown in FIG. 2, only slave tank 32 has been detailed, but it is to be appreciated that a plurality of slave tanks, as indicated in FIG. 1, may be utilized if found necessary or convenient.
  • Master tank 23 and the slave tanks associated therewith may be of the same size and may be connected by three-fourths inch lines (as may reservoir 17 also be connected to master tank 23). In a working embodiment, it was found that tanks with a diameter of about one foot and a height of about 28 inches (about 12% gallon capacity) were operationally satisfactory.
  • Slave tank 32 is connected through line 37 to associated article coating station 42, while, as shown in FIG. 1, slave tanks 33, 34, and 35 may be connected in like manner through leads 38, 39, and 40, respectively, to associated article coating stations 43, 44, and 45, re-
  • Article coating stations 42 through 45 have not been shown in detail herein, it being understood that each of these stations may include a hood (not shown) into which vapor that includes heat decomposable metallic coating compound'is introduced to coat glass articles with a thin coating of metal oxide as they pass through the hood while the articles retain heat of formation above the decomposition temperature of the heat decomposable metallic compound utilized.
  • the coating material supply is shown to include barrels, or drums, l1 and 12. These drums may be conventional and the material to be utilized is stored therein, preferably in liquid form. Such material may, for example, be titanium tetrachloride, tetraisopropyl titanate or tin tetrachloride, as brought out hereinabove, where the coating material is to be utilized for the coating of glass containers.
  • the barrels, or drums, l 1 and 12 are preferably easily removable for supply replenishment and other purposes, and accordingly, are mounted on U-shaped support frame 47 the legs 48 of which have wheels 49 conventionally mounted near the free ends and the central portion of which has a wheel 50 conventionally pivotably mounted thereon.
  • Upstanding supports 52 extend from frame 47 rearwardly of wheels 49 and the free ends of supports 52 are conventionally secured to the sides of the associated barrel (11 or 12) at 53 so that the barrels may pivot in a vertical plane to facilitate connection to reservoir 17 and/or emptying or cleaning of the barrel.
  • the lower rear portion of the barrel can rest on the top of frame 48 above wheel 50 (and could, of course, be blocked conventionally at any desired angle).
  • Barrels 11 and 12 are operationally positioned adjacent to reservoir 17, as shown best in FIG. 2, so that each barrel can be connected with both an outlet line (14 or 15) and with an air return.
  • air return 56 for barrel 11 has conduit 57 connected to barrel 11 and parallel connected conduits 58 and 59 connected between reservoir 17 and conduit 57, the latter connection being achieved through a valve 60 which connects conduit 57 to either conduit 58 or 59 depending on valve positioning (this valve could also be utilized to disconnect conduit 57 from both conduits 58 and 59 and eliminate the unnumbered separate shut-off valve indicated in conduit 57 near the top of barrel l1).
  • Conduit 58 is connected with reservoir 17 by means of coupling, or fitting, 62 which extends into the reservoir 17 a short distance, preferably about one inch.
  • Fitting 61 which connects conduit 59 with reservoir 17 opens only into the top of the reservoir and does not extend downwardly therein, as best shown in FIG. 3.
  • air return conduit 64 includes conduit 65 connected to the top portion of barrel 12 through an unnumbered shut-off valve, whileconduits 66 and 67 connected in parallel, are connected to reservoir 17 and to conduit 65 through valve 68.
  • Valve 68 like valve may be utilized to open conduit to either of conduits 66 and 67 or to neither of them.
  • Fitting 69 does not extend. into reservoir 17 and opens conduit 67 to the top of the reservoir while fitting 70, like fitting 62, extends into reservoir 17 a short distance, preferably about 1 inch. If desired, fittings 61 and 69 may also extend into the reservoir a short distance, and if this occurs, fittings 62 and 70 must extend further into the reservoir by about 1 inch than do fittings 61 and 69.
  • an air supply line 72 is also connected to reservoir 17 by means of a fitting 73 which opens the air supply line into the top of the reservoir.
  • Line 72 is connected with a pressurized source (not shown) so that a small pres sure is maintained within the reservoir. This may be readily accomplished by connnecting line 72 to a source of dry air (i.e., air dried to a very high degree, such as to a dew point of -50 F. or more) having a pressure of not more than about 1 pound per square inch (1 p.s.i.).
  • reservoir 17 includes an elongated cylindrical body portion 75 both ends of which are closed by end plates 76 (front) and 77 (rear).
  • Reservoir 17 is sized and positioned with respect to the bulk source utilized (barrels l1 and 12 as shown) so that the reservoir can remain filled with liquid by gravity feed from the storage source to the reservoir.
  • this positioning arrangement is preferably with the top of the reservoir about level or just below the bottom of barrels 11 and 12.
  • two conventional 55 gallon drums were utilized as storage barrels 11 and 12 and a reservoir of about 15 inches diameter and a length of about 6 feet was satisfactory to give the desired performance.
  • the reservoir (and conduits) must of course, be sized to handle the expected maximum flow of coating material and positioned in view of known factors such as atmosphereic pressure differentials to be encountered.
  • the air returns 56 and 64 from reservoir 17 to the drums l1 and 12 provide an automatic feed selection arrangement. Since the barrels are connected to a double conduit return, anoperator, after initially connecting two barrels filled with coating material to the reservoir, turns valve 60 (for example) to connect reservoir 17 with conduit 59 and turns valve 68 to connect reservoir 17 with conduit 66. Since conduit 59 is connected with the top of the reservoir while conduit 66 is connected with fitting 70 which extends into the barrel, the reservoir is filled from drumll since an uncovered air return is provided through conduits 57 and 59, while the air return conduit 66 is effectively closed since fitting 70 extends into the liquid in the filled barrel to preclude a return of air to drum 12.
  • This arrangement causes the coating material from drum 11 to be gravity fed into the reservoir to keep the reservoir full until drum 11 is empty. After drum 11 empties and the level of coating material in the reservoir drops to a point sufficiently low to expose the lower end of fitting 70, air is then permitted to return to drum 12 and this drum would then be emptied into the reservoir to maintain Y the reservoir at a level roughly equal to the bottom of fitting 70 extending into the drum (preferably about 1 inch). An operator would then avoid depletion of the coating material supply by connecting a new barrel in place of barrel 11 (or by filling barrel 11). At this time,
  • the operator would preferably change valve 68 to connect barrel 12 through conduit 67 (which would then allow the reservoir to completely fill since conduit 67 opens into the top of reservoir 17) and changes valve so that conduit 58 is connected with the barrel which conduit is connected to fitting 62 which extends down into the barrel) so that the contents of barrel 11 would not then feed into the reservoir until barrel 12 was empty.
  • a level indicator could be conventionally mounted in barrels 11 and 12 to facilitate manual monitoring of the barrels in conventional manner. If fittings 61 and 69 extend into the reservoir so that fittings 62 and 70 extend into the reservoir about 1 inch further than do fittings 61 and 69, the level in the reservoir will, of course, at no time be higher than the shortest of these fittings. Operation will be unaffected, however, and such an arrangement may often be preferred.
  • Reservoir 17 is connected to conduit 18 through fitting 79 which opens from the bottom of the reservoir through front end plate 76.
  • the outlet conduit is connected to pump 20, as shown in FIG. 2, and if desired , a shut-off valve can be inserted into the line, as indicated in FIG. 2.
  • Pump 20 is preferably utilized in a constantly energized state during normal operation to thus maintain a constant flow of material between the main tank 23 and the reservoir 17.
  • the inflow to main tank 23 is maintained through conduit 21 from the pump 20 into the bottom portion of the main tank 23 through fitting 83.
  • a return conduit 80 is connected to reservoir 17 from main tank 23 with the return being connected to reservoir 17 at the top center thereof through fitting 81, and the return conduit is connected to the upper portion of the main tank 23 by means of fitting 84, as shown in FIG. 2.
  • Fitting 84 for return conduit'80 preferably opens into main tank 23 a short distance downwardly from the top of the tank so that a level control can be inserted into the tank as is brought outmore fully hereinafter. It is found that with a level control as shown in FIG. 5, the return conduit preferably opens into main tank 23 about nine inches below the top of the tank.
  • the coating material from the main tank to the slave tanks is fed through conduit 30 connected to the main tank by means of fitting 85 which opens into the bottom portion of the main tank as shown in FIG. 2.
  • a shut-off valve can also be inserted into this line if desired.
  • the top of main tank 23 has an aperture to receive a fitting 86 therein which allows insertion of a level indicator such as level indicator 24 shown in FIG. 5.
  • the electrical connection of the level control indicator 24 is by means of a plurality of wires leading from switches in the level control unit. These wires (four as shown in FIG. 6) are conducted through conduit 25 to the alarm circuitry 27, as is brought out more fully hereinafter (conduit 25 can, of course, be eliminated and the wires conducted to the alarm circuitry without additional covering if desired).
  • slave tank 32 (this being the only slave tank detailed in FIG. 2 although it is to be ap pr'eciated that additional identical slave tanks, such as slave tanks 33, 34, and 35, may be utilized as brought out hereinabove) is connected to conduit 30 at the bot tom portion thereof by means of fitting 88 so that when the master tank 23 is connected with one or more slave tanks by conduit 30 as an open line, the connected slave tanks are gravity fed from the master tank and hence will fill to a predetermined level determined by the relative positioning of each slave tank with respect to the master tank. If, as preferred, the slave tanks utilized are positioned at the same level as the master tank, then the slave tanks will fill to the same level as the master tank by gravity feed. Each slave tank may, if desired, have a shut-off valve which can be closed, as can conduit 30, as indicated in FIG. 2.
  • slave tank 32 has an air inlet at the top of the tank with conduit 90 leading from a pressurized air supply source (not shown) to fitting 91 with the fitting extending into the bottom portion of the tank as indicated in FIG. 2.
  • Dry air is conventionally injected into the slave tank (preferably at about 10 p.s.i. or less) and bubbled therethrough so that vapor laden with coating material may thereafter be conducted from the slave tank through conduit 37 to the article coating station for applying a thin coating to glass articles as is described in greater detail hereinabove.
  • a level control is shown which can be utilized with the system of this invention to provide an indication of level deviations in the master tank beyond predetermined minimum and maximum levels.
  • a shaft, or tube, 96 extends downwardly into the main tank and may be secured to the top thereof by a shaft connector 97 to the bottom of the mounting plug, or fitting, 86.
  • a shaft end fitting 98 is conventionally secured to the bottom of shaft 96 to seal the same, while a plurality of shaft unions 100, 101, and 102 are spaced along the shaft, as shown in FIG. 5.

  • the state of fluid level switch 171 depends on the positioning of station 105 on shaft 96, and the state (either open or closed) of switch 171 determines which output from the switching arrangement will be connected with lead 168.
  • One output from switching arrangement 186 is connected by lead 173 to one side of field low fluid level light 174 (the other side of which is connected through lead 175 to line 117) and to one side of low fluid level light 176 (the other side of which is connected by lead 177 to line 117). These lights are preferably red in color and are found at the main (light 176) and auxliary (light 174) panels.
  • the other output from the switching arrangement 186 is taken through lead 178 to controller 180 the other side of which is connected to line 117.
  • Controller 180 is an AC contactor which controls the state of switches 139 and 153.
  • power switch 118 In operation, power is applied to the system by actuating power switch 118 from an off position to an on position. This will energize the power on lights to show that power is available at the system. If desired, test switch 126 can then be actuated to the on position to energize pump on lights 128 and 144 and energize pump motor controller 142 to close switch 147 and thereby energize pump motor 150. Actuation of the test switch 126 to the off position will then de-energize the pump on lights and controller to thus de-energize the motor. If the liquid level is below the predetermined minimum level as established by the position of station 105 of the level indicator 24 within master tank 23, switch 171 will be open and controller 180 will remain de-energized when power is applied. This will cause switch 153 to be in the normally closed position and will thus allow fluid level alarm 155 to be energized until the level is brought up sufficiently in the master tank to close the switch and energize controller 180 to open switch 153 and de-energize the alarm.
  • the pump will constantly pump coating material into the master tank and the level will remain constant withthe excess over that utilized at the slave tanks being returned to the reservoir via the return line (the return line opens into the master tank about mid-way between the high and low level sensing stations 104 and Termination of pump energization can occur by power disruption to the system, by actuatingthe power switch 118 to the off position, or by opening either stop switch 132 or 134. In addition, automatic termination of pump energization will occur if the liquid level in the main tank should either rise or fall to a level to change the state of either switch 161 (high level) or switch 171 (low level).
  • controller 180 will be de-energized and this will close switch 153 to actuate the alarm 155 and open switch 139 to de-energize pump motor controller 142 and hence open switch 147 to stop the pump motor 150. If the high level switch 161 is actuated, controller 180 is de-energized by terminating the power thereto and power is applied to the high fluid level lights 164 and 166. If the low level switch 171 is actuated, controller 180 is likewise deenergized by terminating the power thereto, but in this event power is applied to the low fluid level lights 174 and 176. After the problem with respect to fluid level in the master tank has been corrected, then normal operation can be resumed by actuating the start or field start switches. A high level could occur, for example, due to a blocked return line to the reservoir, while a low level could occur, for example, due to a lack of supply of coating material.
  • the system of this invention provides a heretofore unavailable means for handling and distributing fluids that is particularly useful in handling and distributing coating materials for use in coating glass articles.
  • a liquid handling system comprising: a slave tank for supplying liquid to utilization means; a master tank; conduit means for connecting said slave tank to said master tank, said slave and master tanks being positioned so that predetermined relative liquid levels exist therebetween when said conduit means is open between the slave and master tanks; a storage reservoir including a reservoir tank and a plurality of bulk storage tanks, air return means connecting said reservoir tank and the plurality of bulk storage tanks, said air return means having selectible first and second parallel conduits with a first conduit extending into said reservoir tank a greater distance than does the second conduit so that a first bulk storage tank with a first conduit selected is precluded from supplying liquid to said reservoir tank until the liquid level falls below said first conduit extending into said reservoir tank, while a second of said bulk storage tanks with said second conduit selected will continuously provide liquid to said reserve tank and preclude liquid supply from the first of said bulk storage tanks until the second of said bulk storage tanks is empty.
  • a fluid distributing system comprising: a reservoir; first and second storage tanks; first and second conduits connecting said first and second storage tanks to said reservoir; and first and second'air return means connecting said reservoir to said first and second storage tanks, said air return means including means for preselecting and causing automatic successive supply- 12 ing of fluid from said storage tanks to said reservoir.
  • each of said air return means includes first and second air return conduits connected in parallel with one another, said first air return conduit extending into said reservoir a greater distance than does the second, and wherein each of said air return means includes a valve for selecting which of said first and second air return conduits are connected with said associated storage tank.
  • a liquid handling system for coating material used in applying a coating to glass articles comprising: a slave tank for supplying coating material in liquid form to coating material utilization means; a master tank; conduit means for connecting said slave tank to said master tank, said tanks being positioned so that a predetermined relative liquid level of coating material exists therebetween when said conduit means is open between the tanks; a coating material storage reservoir; and means for connecting said storage reservoir to said master tank so that coating material in liquid form is supplied from said reservoirto said master tank to maintain the level of coating materials in said master tank substantially constant during normal operation of the system.
  • a liquid handling system for coating material used in applying a coating to glass articles comprising: a plurality of glass article coating stations for receiving glass articles to be coated with a predetermined coating material; a plurality of slave tanks equal in number to said article coating stations with each said slave tank being associated with a different one of the said article coating stations to supply coating material thereto; a plurality of first conduits for connecting each of said slave tanks to an associated coating station; a master tank; second conduit means for connecting said master tank with said slave tanks, said tanks being positioned so that when open to one another through said second conduit means said tanks attain a predetermined level of coating material relative to one another; a reservoir of coating material; third and fourth conduits connecting said master tank with said reservoir, said conduits opening into said master tank atpredetermined vertically spaced positions; a pump connected with said third conduit to cause coating material to be constantly pumped to said master tank and the excess then returned to said reservoir; a plurality of bulk storage tanks; a plurality of fifth conduits for individually connecting each of said bulk storage tanks to said reservoir
