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, aluminum, or other acceptable material in a series-of presses, 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.
  • 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 that blanks and forms the shells, a ring curler for 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.
  • 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 eliminates the disadvantages and problems inherent in the prior art and provides certain feature unique to a shell press.
  • a shell press having a blanking and forming die.station and a curling die station operated by a common slide assembly disposed in the shell press, thereby eliminating the need of having to stack formed and blanked shells.
  • 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 comprises 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.
  • 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 present invention provides a shell press for making shells for beverage cans and the like comprising a blanking and forming die station and a curling die station, both of which are operated by a common slide assembly disposed in the shell press.
  • An ejector is provided for ejecting a blanked and formed shell from the blanking and forming die station onto a fluid conveyor device extending between the blanking and forming die station and curling die station.
  • This pneumatic transfer system comprises a fluid conveyor track leading to the die station and a guide track leading away from the die station. Connected to the reciprocating slide to reciprocate therewith are a first wall member having a hole therein disposed between the fluid conveyor track and die station and a second wall member having a hole therein disposed between the guide track and die station.
  • a reciprocating mechanism is provided to reciprocate the slide downwardly from its uppermost position to an intermediate position wherein the first wall opening is aligned with the fluid conveyor track to permit a part to be fluid conveyed into the station, and then to a lowermost position where the part is shaped by the tool elements. Thereafter, the reciprocating mechanism moves the slide member upwardly from its lowermost position to a second intermediate position wherein the second wall opening is aligned with the guide track and a source of air is caused to emit a pulse of air against the shaped part to eject it through the second wall opening onto the guide track. The reciprocating mechanism then moves the slide upwardly to its uppermost position for subsequent reciprocative movements.
  • a further aspect of the present invention is an air transfer apparatus for moving a part from a first die station to a second die station in a press installation.
  • the air transfer apparatus comprises a guide track extending between the die stations and having an upwardly facing surface, opposed sides extending substantially the length of the upwardly facing surface, and a downwardly facing surface above the upwardly facing surface and extending substantially the length thereof.
  • the facing surfaces and opposed sides generally define therebetween an elongated space extending between the die stations.
  • a hollow tube member is disposed in the guide track and has a diameter much smaller than the transverse distance between the opposed sides, and has a plurality of openings therein to provide fluid communication between the hollow tube and the elongated space.
  • the openings are shaped to provide air flow velocity components in the elongated space directed toward the second die station when a flow of air is supplied to the hollow tube by a source of air flow connected thereto.
  • Another object of the present invention is to provide an air transfer system which in part utilizes a hollow tube having a plurality of openings therein for air conveying a shell from a blanking and forming station to a curling station.
  • a further object of the present invention is to provide a pneumatic system for air conveying a part to a die station and for ejecting the part therefrom with a pulse of air.

  • 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 wherein 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, hollow tube 72 extending the length of guide track 7 0, 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 7 6.

  • guide track 70 has a lower surface 94 with a groove 96 centrally disposed -longitudinally therein.
  • hollow tube 72 Secured within the length of groove 96 is hollow tube 72 having one end 100-closed and the other end 102 (Fig. 1B) connected to connector 76 to supply high pressure air flow through the length of hollow tube 72.
  • Important to the invention is the very small diameter of hollow tube 72 in relation to the width of lower surface 94 and the diameter of a shell 66.
