  • Metal cans are made by either one of two processes.
  • One process, the two-piece can process involves forming a drawn cup from a cylindrical slug of metal and then deepdrawing the cup to a can configuration.
  • the other process, the three-piece process involves forming a cylindrical can body from a sheet of metal and then attaching two lids or ends to the opposite ends of the body.
  • the invention of this application is concerned only with the application of protective coatings to three-piece cans.
  • the cylindrical bodies are formed by wrapping a sheet of metal around a so-called stubhorn.
  • the sheets 13 Prior to formation into the cylindrical configuration, the sheets 13 are generally roller coated .on all but the lateral edges with a protective coating of lacquer or other similar material.
  • the lateral edges of the sheet After formation into the cylindrical, configuration, the lateral edges of the sheet are either butted or overlapped and secured together by either a welded seam, a soldered seam, or a cemented seam.
  • the seam area and the previously uncoated lateral edges of the sheet are then spray coated with an epoxy or phenolic lacquer or some modification of these materials.
  • the complete interior of the cylindrical body is coated with another complete protective coating which is generally of vinyl lacquer although numerous other materials, as, for example, resins, lacquers, waxes and paints, are applied for this same purpose, i.e., to afford protection of the contents of the can against contamination by the metal.
  • another complete protective coating which is generally of vinyl lacquer although numerous other materials, as, for example, resins, lacquers, waxes and paints, are applied for this same purpose, i.e., to afford protection of the contents of the can against contamination by the metal.
  • a tasteless and odorless protective coating material to the interior of the can.
  • the protective material which is applied to the interior of the can must be continuous throughout the entire interior surface. Any pin holes, cracks, or imperfections in the integrity of the coating render the can unsuitable for most applications.
  • the purpose of this stripe is to provide an impervious layer of protective material over that portion of the body which is most vulnerable to imperfections and where failures most often occur.
  • an airless spray technique for intermittently applying a stripe of lacquer to the inside seams of can bodies as the cans pass an airless spray nozzle attached to the end of the stubhorn.
  • the spray nozzle is so positioned on the stubborn that it is located on the interior of the can bodies as the bodies pass the stripping station.
  • One of the problems encountered in spraying a stripe of protective material onto the seam of a can body is that of confining the spray to a stripe approximately one-half to 1 inch in width, depending upon the can application, without having the spray bounce up or fog onto the area or side of the can wall adjacent the stripe.
  • This confining of the stripe to avoid its overlapping or splashing onto the side walls of can bodies is particularly critical in the case of soldered seam cans.
  • Common practice is to spray the seam of the can with the protective stripe prior to soldering of the seam but after the seam has been formed and overlapped. After spraying, the seam is soldered and the area adjacent the seam is exposed during soldering to a temperature of 700900 F during which the stripe of protective material is cured.
  • the complete interior of the can body is sprayed with a coating of lacquer or protective material but one which cures at a lower temperature, as, for example, 300 F. If any high curing temperature seam striping material inadvertently is sprayed onto the area adjacent the stripe,.that lacquer is not subjected to the 700900 F. seam temperature and is therefore never cured, either during the soldering operation or during the subsequent curing of the low curing temperature material sprayed onto the complete interior of the can.
  • Still another objective of this invention has been to provide an apparatus for spraying a stripe of protective material over the seam of a can with a minimum quantity of material while stillobtaining a continuous uniform coating of material over the seam.
  • This nozzle has an axial bore terminating in a fan-shaped nozzle orifice. Lacquer is supplied to the axial bore through a radial passage. The nozzle is mounted in a bore which includes a turbulence chamber behind the end of the nozzle. The combination of this radial injection of liquid into the nozzle, together with the provision of a turbulence chamber behind the nozzle, results in the emerging liquid spray being atomized much more quickly and closer to the nozzle orifice than has heretofore been possible.
  • Still another aspect of this invention is predicated upon the concept of utilizing two air nozzles located alongside the liquid spray nozzle to contain the edges of the atomized spray to the can seam area.
  • these air nozzles are so connected to the gun that the air spray is turned onand off simultaneously with the intermittent emission of liquid spray from the protective material nozzle.
  • the air curtains which emerge from these airnozzles are generally fan-shaped and contain the liquid spray fog along the edges so as to prevent that fog from rolling out onto the area adjacent the stripe.
  • Still another aspect of this invention is predicated upon the empirical determination of nozzle design and conditions under which an airless spray stripe may be applied to the interior seam of a can body in a uniform continuous, film which meets all can industry standards in terms of continuity, uniformity, weight of material, and application of the stripe to a confined area.
  • Still another aspect of this invention is predicated upon the development of a new and improved nozzle which has better spray atomization characteristics close to the nozzle orifice than has heretofore been possible.
  • FIG. 1 is a diagrammatic illustration of a portion of a can formingline including the invention of this application.
  • FIG. 2 is an enlarged view, partially in cross section, of the end of the can forming line stubhorn of FIG. 1.
  • FIG. 3 is an end elevational view of the end of the stubhorn including the spray gun taken on line 3-3 of FIG. 2.
  • FIG. 4 is a cross sectional view through the spray gun of FIG. 1.
  • FIG. 5 is another cross sectional view through the spray gun taken in a plane normal to the plane 'of FIG.
  • FIG. 6 is an enlarged cross sectional view through the spray nozzle taken on line 6-6 of FIG. 2.
  • FIG. 7 is a top plan view of the spray pattern which emerges from the liquid spray nozzle and the two air nozzles of FIG. 6.
  • FIG. 1 there is illustrated diagrammatically a standard can production line used in the production of cylindrical can bodies.
  • This line includes a stubhom 10 which serves as a mandrel around which can bodies 1 l are formed as they pass downstream.
  • the can bodies 11 are moved longitudinally over the stubborn from a magazine 12 by lugs on a chain conveyor which engage the rear edge 13 of the bodies and push them along the stubhom.
  • bodies pass off the stubhom after having been formed into cylindrical configuration, they move into a network of rails 15 through which they then pass'during continued formation of the cans.
  • the ends of the sheet metal from which the body is made are overlapped or joined. If the bodies are to be'seamed by adhesive, the adhesive is placed in the overlapping seams at the seaming station indicated by the numeral 14. Alternatively, if the bodies are to be welded, they are butt welded at this station 14. And if the bodies are to be soldered, they are crimped together at the seaming station 14. As the bodies pass off the stubhom l0 and into the rails l5,
  • soldered can bodies then require passage through a soldering station downstream of the striping station 16 to complete formation of the seam but the adhered and welded seams are completely formed when the bodies enter the rails 15.
  • a spray gun20 is secured to the end of the stubhorn 10. This gun is so positioned that the can bodies pass over itbefore passing into the rails 15
  • the gun 20 is'secured to the end surface 21 of the stubhom by a generally U-shaped bracket 22 secured onto the end of the stubborn by a plurality of bolts 23.
  • Bolts 19 similarly secure the gun 20 to. the opposite or downstream end 24 of the bracket 22.
  • the bracket 22 maybe omitted and, in fact, in one preferred embodiment is omitted in which case the gun 20 is secured directly onto the end of the stubhom.
  • the spray gun 20 is of the so-called circulations flow type; that is, there is a continuous flow of liquid or coating material to the gun through a liquid inlet line 25. There is also continuous flow of liquid or coating material from the gun via a line 26 (FIG. 4 and 5). As a result of this continuous flow, the temperature of the liquid material may be'maintained constant in the gun even when the gun is not in use and when the liquid would otherwise be stationary in the gun.
  • the gun contains a check valve, indicated generally by the numeral 30, operable to open and close a passage 31 leading to an orifice 32 of a nozzle .33 in synchronization with movement of cans past the orifice 32.
  • the check valve is pneumatically opened by air pressure supplied to the gun via an air line 35 and is spring biased to a closed position. Air pressure at approximately 60 psi is supplied to the gun in the line 35 from an air pressure source 36 through a solenoid con trolled valve 37.
  • An electric photocell circuit including a photocell 38 and receiver 39 control the flow of electric current to the solenoid of the valve 37.
  • the sender is operable to direct a light beam through a hole 41 in the. stubhom 10 so that cans entering the striping station 16 break the'circuit and trip a solenoid 42, thereby causing the valve 37 to be opened and air pressure supplied via line 35 to the gun.
  • the solenoid valve portion of the valve 37 is an onoff solenoid valve. It is used in combination with a conventional four-way spool valve 42, to one end of which air is alternately supplied from a source 36 at a pressure within valve 37 at all times, so that when the solenoid electrical circuit is broken, the solenoid valve connects the high .pressure end of the spool valve 37 to atmospheric pressure and a low pressure psi) at the opposite end then moves the spool toward the high pressure end. When the electrical circuit again energizes the solenoid, the valve 37 connects the high pres sure end of the spool to 60 psi, and the spool immediately moves toward the low pressure end against the resistance offered by the low air pressure in line 43.
  • valve 37 may be more reliable with a low pressure line connected to the one end of the valve than it is when it utilizes spring return. It has also been found that the solenoid valve may act fast enough when used as a pilot valve to control flow to the gun but that if used with higher flow capacities without a second stage spool valve it may be too slow to keep up with current can production lines.
  • the gun 20 generally comprise a two-piece cylindrical body 45 within which there is an axial or central bore 46.
  • This bore comprises a fluid chamber 47 adjacent the front end of the body, a smaller diameter connecting chamber 48, and a large diameter piston chamber 49.
  • the rear side of the piston chamber 49 is open to the atmosphere through a small diameter section 51 of the bore 46.
  • An end cap 52 is secured to the body 45 by bolts (not shown) and closes the fluid chamber 47.
  • the cap 52 comprises a central disc 53 from which hub sections 54, 55 extend rearwardly and forwardly, respectively.
  • the rearward hub 54 fits within, and with an O- ring, seals the fluid chamber 47.
  • the forwardly extending hub section 55 has an inwardly extending flange 56.
  • An axial bore 57 extends through the cap 52 and comprises a large diameter rear section 58 and a smaller diameter front section 59.
  • This insert 61 defines the seat of the check valve 30.
  • the insert has a stepped axial bore which comprises a large diameter rearward section 62 and the small diameter passage 31 interconnected by shoulder 63.
  • An arcuate seat is machined into the shoulder at the point where the shoulder joins the small bore 31. This seat is configurated to cooperate with a generally semispherical end 64 of the check valve head 65 to form a seal.
  • the nozzle assembly 33 is bolted onto the flanged end 56 of the end cap 52.
  • this assembly 33 comprises a nozzle mounting block 70 and a carbide nozzle top 71.
  • the block 70 is fixedly secured onto the end cap by a pair of bolts 72.
  • This block 70 has one bore 73 which communicates with and is coaxial with the outlet passage 31 of the gun and a second passage 74 which intersects at 90 the first passage 73.
  • This second passage 74 also intersects the apex of an inverted V-shaped groove 69 formed in the bottom of the block 70.
  • This second bore or passage 74 extends completely through the block 70 and has a small diameter threaded end section 75, an intermediate diameter section 76, and a counterbored end section 77.
  • the carbide tip 71 is brazed or otherwise fixedly secured in the intermediate section 75 with a shoulder 78 of the tip abutting the counterbored shoulder ofthe bore 74.
  • the tip 71 has an axial central bore 79 extending through it and intersected at a right angle by a transverse bore'8l.
  • the bore or aperture 81 communicates with and is coaxial with the bore 73 of the mounting block so that liquid may be transmitted through the bore 73 into the nozzle bore 79.
  • a nozzle clean-out screw 82 threaded into the threaded small diameter section of the bore 74.
  • the end 83 of this screw is spaced from the rear end surface 84 of the nozzle tip so that a turbulence chamber 85 is defined by the rear surface 84 of tip 71, intermediate section 75 of the bore 74, and the inner end 83 of the screw 82.
  • the outer end of the nozzle tip 71 is generally hemispherical in configuration.
  • the elliptical-shaped orifice 32 is machined into the top of the dome so as to intersect at a right angle the axial orifice 79 of the tip. Conventionally, this elliptical orifice is machined into the dome by a tapered grinding wheel. Liquid emerging at a high pressure or as a high pressure stream (as, for example, at 200 to 1,000 psi) from the elliptical-shaped orifice atomizes and assumes the elliptical pattern depicted by the dashed line 87 of FIG. 7
  • the film In order to apply a sufficiently thin film of lacquer or other coating material to the seam area A of a can and to limit the sprayed material to the stripe area or to the area immediately adjacent this stripe area, the film must be finely atomized before it strikes the can surface. If not sufiiciently atomized, the spray or fog strikes the substrate, or the can side wall, with sufficient velocity and impact that it bounces and splashes onto the can side wall to form an oversprayed area on the area adjacent the same area A.
  • One aspect of this invention is predicated upon the determination that the overspray problem or the splash problem is materially reduced or eliminated by the turbulence chamber 85.
  • a threaded plug or screw 82 By inserting a threaded plug or screw 82 into the threaded bore 75 of the nozzle mounting block but having the end 83 of the screw terminate short of the rear surface 84 of the nozzle tip 71, there is provided a turbulence chamber 85 immediately behind the nozzle tip.
  • This turbulence chamber in combination with the injection of liquid into the nozzle tip via a radial port 81 has the effect of materially reducing the distance D required for the spray to atomize after emerging from the nozzle orifice 32.
  • this arrangement reduces the distance D to approximately one-fifth the distance otherwise required for atomization when the same liquid is directed axially through the same size nozzle tip at the 7 same pressure and temperature.
  • the distance D is reduced, the degree of atomization of the spray is improved and the velocity with which it strikes the substrate or can body is materially reduced.
  • This finer atomization and reduction of particle velocity in turn eliminates the problem of the spray bouncing and climbing up the side walls 93 of the can outside the can stripe area A.
  • a pair of air curtains 94, 95 are preferably provided adjacent the opposite ends of the elliptical-shaped pattern 87 of the liquid spray- These curtains are also elliptical in cross sectional configuration at the point where they strike the substrate or can bodyadjacent the stripe 17. As indicated by thecross hatched patterns 94A, 95A in FIG. 7, these air curtains 94, 95 have the effect of chopping off the ends 87A, 87B of the fan-shaped pattern 87 of atomized liquid spray so as to confine it to a width W.
  • air is supplied to a pair 'of elliptical-shaped nozzle orifices 97 and 98 in a pair of nozzles 99 and 100.
  • This air is supplied to the nozzles in synchronization with opening and closing of the check valve 30 of the gun 20.
  • the nozzles 99 and 100 are mounted in the ends of tubes 101 which extend upwardly and are mounted in a manifold block 102 secured to the gun.
  • the block 102 has a central passage 103 which communicates with the passages within the tubes 101.
  • the passage 103 is supplied with air under regulated pressure of from 20 to 70 psig from the pneumatic line 35. It is also connected to a pneumaticline 35A of the gun. Consequently, air is supplied to the nozzles 99 and 100 in synchronization with opening and closing of the check valve of the gun.
  • can bodies 11 are formed over the stubhorn 10 at the rate of approximately 550 plus or minus 50 cans per minute. This rate varies from one can manufacturer to another, but quite commonly today averages approximately 5 75 can bodies per minute per line in the production of standard beer or beverage cans.
  • a solder, adhesive or weld is commonly applied to the overlapping or abutting edges 18 of the sheet at the seaming station 14. This station is located immediately in front of the striping station 16 where the stripe 17 of protective material from the nozzle 33 and spray gun 20 is directed onto the seam.
  • the seam is subsequently completed and the striping material simultaneously cured by the application of soldering heat to the seam at a subsequent soldering station.
  • this heat raises the temperature of the seam to above 700-900 F. so as to cure the protective coating of the stripe during the soldering operation.
  • the striping material is either heat or air cured at a much lower temperature farther down the can production line.
  • the emission of liquid spray from the nozzle 33 and the emission of the air curtains from the nozzles 99 and 100 are turned on and off in synchronization withv movement of the can bodies 11 over the stubhom and through the striping station. This is accomplished by the can bodies interrupting a light beam of the photocell sender and receiver unit 38, 39.
  • the solenoid control circuit Upon interruption of the light beam and after a predetermined time delay built into a solenoid control circuit, the solenoid control circuit is operable to shift the solenoid and move a valve spoolof the valve 37 so as to connect the air line 35 to the source of air pressure 36, thereby connecting a forward end chamber 104 of the check valve control piston chamber to high pressure, i.e., 60 psi air.
  • a timer circuit interrupts the signal to the solenoid causing it to be de-energized and the control circuit to be reset preparatoryto interruption of the light beam by the next following can.
  • low air pressure i.e., 20 psi
  • spring pressure then moves the spool of the valve 37 to the position in which the air line 35 is connected to atmospheric pressure.
  • the preferred nozzle is one which has a flow rate of 0.015 gallons per 1 minute of water at 500 psi and at ambient temperature.
  • the nozzle orifice is preferably spaced 1 /4 inch from the can seam and lays down a protective stripe of material nine-sixteenths inch to eleven-sixteenths inch in width W.
  • the resulting stripe of material when subsequently cured weighs approximately 5 or 6 milligrams. Including the overspray, this stripe never exceeds l 1/ 16 inch in width W, which width is adequately heated to curing temperature of approximately 750 F. during the subsequent soldering operation.
