Definitions

  • the invention relates to an air transfer system, and more particularly to an air transfer system for a shell press having a blanking and forming die station and a curling die station commonly operated therein.
  • Beverage cans, food cans and the like have a can body and separately manufactured ends, which are called shells that are sealed to the can body.
  • the shells are manufactured from sheet steel, aluminium, or other acceptable material in a series of pressures, wherein the shell is blanked and formed in one press and then transported to a second press which curls the edges of the blanked and formed shell.
  • the uncurled shell has a peripheral edge that is generally perpendicularly disposed to the main body of the shell, and, before the shell is stacked and then sealed to the beverage can it must first be curled at its peripheral edge and then coated with a sealant which forms a resilient gasket against the can body.
  • US-A-3537291 describes apparatus for forming such end closures for cans.
  • a major problem currently existing in the industry is directly related to the use of separate presses to blank and form the shell and to curl the shell.
  • the blanked and formed shells may first have to be stacked one upon the other and then transported to the curling die station to be curled, or the situation may arise wherein it is necessary to store stacked blanked and formed shells due to unforeseen circumstances, for example, an inoperable curler.
  • the shapes of the blanked and formed shells permit them to be conveniently stacked since one shell tightly nests within another.
  • the blanked and formed shells tightly nest one upon the other, it is virtually impossible to mechanically cut an individual shell from a tightly nested stack of shells. This requires the shells to be stored in an unstacked state, which requires considerable space and is time consuming, costly and inefficient.
  • the blanking and forming die station and curling die station are in close proximity with one another so that the blanked and formed shells may be transported to the curling die station, for example, by use of a conveyor assembly.
  • the shells are generally blanked and formed from the strip stock in groups of twelve, fourteen, or sixteen.
  • a group of sixteen may be blanked and formed from the strip stock in two rows of eight, which rows are staggered relative to each other to minimize the strip stock skeleton remaining after the blanking and forming operation. Since it is not practical to stack the blanked and formed shells, it is necessary to keep them separated from each other between the blanking and forming die station and curling die station.
  • a typical prior art embodiment of the above shell press installation comprises a double acting press than blanks and forms the shells, a ring curler fur curling the blanked and formed shells, and a conveyor assembly extending therebetween.
  • the blanked and formed shells may be delivered to the conveyor assembly in one of two common ways.
  • the blanking and forming shell press may be designed to tilt towards the conveyor assembly so that the blanked and formed shells slide from the press onto the conveyor for conveyance to the ring curler, or a mechanical kicker-type device may be used with a stationary blanking and forming shell press to eject the blanked and formed shells onto the conveyor.
  • the ring curler generally comprises two rotating rollers between which the shells pass to be curled.
  • Another typical prior art embodiment which may be a modification of the above described embodiment, uses a die curler in place of the ring curler.
  • the blanked and formed shell is curled at a die station, which is commonly housed in a press separate from the blanking and forming shell press and operated independently thereof.
  • the distance between the blanking and forming shell press and the die curler may be such that a conveyor assembly may be used to transport blanked and formed shells to the die curler.
  • Stacking for transporting to the die curler is not practical due to the tight nesting of a stack of blanked and formed shells.
  • pneumatic systems which generally comprise a large plenum and duct assembly.
  • parts such as bottles, cans, records, silicon wafers and the like are transported along a guide track overlying the ducts.
  • the ducts have a plurality of openings disposed therein and the plenum provides a source of low pressure air which flows through the ducts and out the openings to convey the part from one area to another.
  • This type of system poses numerous disadvantages when adapted to a shell press wherein a plurality of shells are formed simultaneously.
  • shells are blanked and formed in groups of twelve, fourteen, or sixteen and in rows which are staggered relative to each other such that shells formed in one row overlap shells of adjacent rows. Therefore, it is desirable to transport alternate rows along different paths or tracks, which may be disposed relative to each other in a vertically adjacent manner. In such an arrangement, it is not practical or efficient to utilize the pneumatic systems of the prior art because of the large size of the ducts that provide air flow to the tracks. Such prior art systems would be difficult to adapt to a blanking and forming die station and a curling die station operated in the same shell press, and would also require an undue amount of material and space.
  • the present invention provides a shell press for making shells for beverage cans and the like, comprising:
  • the curled shells may be easily stacked and, more importantly, easily cut mechanically from a stack.
  • a further advantage of utilizing a die curler in the same shell press with a blanking and forming die station is the uniform shape of curled edges produced by the die in contrast to the curled edges produced by a ring curler.
  • the pneumatic transfer system provided is compact and easily interfaced between the blanking and forming die station and curling die station in the same shell press.
  • the pneumatic transfer system may comprise two guide tracks extending between the die stations in a double-deck arrangement. Disposed in the upwardly facing. surface of each of the guide tracks is a hollow tube having a diameter much smaller than the width of the guide track or the diameter of the shell being conveyed.
  • Each hollow tube has a plurality of uniquely shaped openings which provide air flow velocity components in the direction of the curling station, and each is connected to an air source which provides a flow of high pressure air. Because the pneumatic system of the present invention utilizes a very small diameter hollow tube in place of the large plenum and duct assembly of the prior art pneumatic systems, the pneumatic system of the present invention is easily installed between a doubledeck guide track arrangement, thereby reducing space requirements and costs.
  • the present invention minimizes the number of dented shells caused by mechanical kicker-type devices in ejecting the shells from a particular die station.
  • an ejecting or escapement mechanism which directs a pulse of air against a curled shell to eject the shell from the curling die station onto a guide track leading therefrom.
  • the invention also provides a shell press for making shells for beverage cans and the like, comprising:
  • shell press 12 comprising blanking and forming die station 14, air conveyor assembly 16, and curling die station 18. Not shown is a strip stock feeder which feeds strip stock 20 to shell press 12 and a scrap cutter for collecting the skeleton of strip stock 20.
  • blanking and forming die station 14 comprises stationary bolster 22 secured to a press bed (not shown) and cutting die retainer assembly 24 secured on the upper surface thereof.
  • Lower forming die 26 the cross section of which is circular in a plain parallel to tin line 28, is securely mounted within cutting die retainer assembly 24.
  • Bolster 22 and cutting die retainer assembly 24 are rigidly connected to the shell press frame (not shown).
  • Lower forming die 26 also includes an annular bead portion 30, which forms a correspondingly shaped bead portion 32 in shell 66.
  • Double action slide assembly 35 comprises blanking slide 36 slidably received on shell press posts (not shown) and forming slide 38 slidably guided by blanking slide 36.
  • Slides 36, 38 are driven by connecting rods and a crankshaft operated by an electric motor (not shown) similar to that shown in US patent 3,902,347.
  • Housing assembly 40 Securely mounted to blanking slide 36 is housing assembly 40, which is slidably disposed with respect to spindle 42 and which retains punch 44 for slidable movement relative thereto.
  • Air pressure from air passage 46 yieldably and continuously urges punch 44 downwardly towards annular cutting die 48 in cutting die retainer assembly 24.
  • Upper forming die 50 is rigidly connected to spindle 42 by retaining rod 52, which is threadedly secured at its lower end to forming die 50 and held against spindle 42 at its upper end by nut 54.
  • Spindle 42 is secured to top plate 56, which is connected to forming slide 38.
  • a dowel 58 prevents rotation between forming die 38 and spindle 42, and forming die 50 has an annular bead portion 60 about its periphery.
  • ejector mechanism 62 has ejector bar 64 in a ready position to eject blanked and formed shell 66 from blanking and forming die station 14.
  • ejector bar 64 is positively moved by ejector mechanism 62 to a position therein it contacts shell 66 and thereafter is positively, rapidly accelerated to eject shell 66 from die station 14 upwardly along incline 68 to air conveyor assembly 16.
  • air conveyor assembly 16 comprises elongated guide track 70, hollowtube 72 extending the length of guide track 70, shaped openings 74 disposed in hollow tube 72, and a source of high pressure air flow (not shown) connected to hollow tube 72 by a suitable connector 76.
  • a suitable connector 76 a source of high pressure air flow (not shown) connected to hollow tube 72 by a suitable connector 76.
  • a support plate 78 extends between blanking and forming die station 14 and curling die station 18 and has incline 68 secured to its left hand end portion by screws 80 received through incline holes 82 and threaded hole 84 in support plate 78.
  • Incline 68 has a narrow neck portion 86 (Fig. 3) for ease of installation only, and upwardly facing surface 88 (Fig. 4) of incline 68 is formed by a tapering end section of guide track 70, which is secured to support plate 78 by screws 90 received through guide track holes 92 and threaded holes (not shown) in support plate 78.
  • guide track 70 has a lower surface 94 with a groove 96 centrally disposed longitudinally therein. Secured within the length of groove 96 is hollow tube 72 having one end 100 closed and the other end 102 (Fig. 1 B) connected to connector 76 to supply high pressure air flow through the length of hollow tube 72.
  • the very small diameter of hollow tube 72 in relation to the width of lower surface 94 and the diameter of a shell 66 is important. This allows hollow tube 72 to be easily installed in narrow spaces, for example, between guide tracks positioned one upon the other to provide fluid conveyance of shells from one area to a second area within shell press 12.
  • Hollow tube 72 has a plurality of shaped openings 74 uniquely stamped therein. Each stamped portion 104 (Figs.
  • hollow tube 72 has a concave surface 106 and a convex surface 108, which faces generally inwardly of hollow tube 72. Consequently, when a supply of high pressure air is provided in hollow tube 72, a flow of high pressure air is discharged through each of the shaped openings 74 providing generally perpendicular and generally parallel velocity components relative to lower surface 94, whereby a shell 66 may be lifted upwardly and moved along lower surface 94 in the direction of the parallel velocity components.
  • opposite side walls 110 (Fig. 5) upstand from lower surface 94 and each side wall 110 has an overhanging extension 112 inwardly disposed over lower surface 94.
  • Side walls 110 are spaced apart a distance slightly greater than the diameter of a shell 66, and remote ends 114 of overhanging extensions 112 are spaced apart a distance slightly less than the diameter of shell 66.
  • Side walls 110 and overhanging extensions 112 permit a shell 66 to be fluid conveyed over lower surface 94 in a manner depicted in Fig. 5. Note that shell 66 is lifted above lower surface 94 by the perpendicular velocity components exiting shaped openings 74 and moved along lower surface 94 by the parallel velocity components exiting shaped openings 74.
  • curling die station 18 comprises curling die retainer assembly 116, lower curling die 118, liftout device 120, upper curling die 122, and sleeve 124.
