  • This invention relates in general to new and useful improvements in machines for manufacturing can bodies, and more particularly to a machine for changing the contour of can bodies so as to have an ornamental appearance.
  • Another feature of this invention is the utilization of water .as the expanding fluid within the membrane whereby during the changing of membranes and in the event of membrane rupture, the spillage will in no way be detrimental and may be easily taken care of.
  • each mold assembly is provided with its own water supply which is of a limited capacity whereby in the event of a line or membrane rupture, the spillage is held to a minimum and a minimum amount of time is required to replace the water supply.
  • the membrane assembly is part of a tool pack and the tool pack is constructed in a manner whereby it may be readily replaced so that when the time comes for a periodical change of membranes, the entire tool pack may be removed and replaced withone have a new membrane fitted thereon.
  • the tool pack of which the membrane is a part is so constructed whereby axial pressure as well as radial pressure is ap-' plied to the membrane, thereby tending to elongate the membrane upon each usage thereof, the elongation of the membrane being effective to reduce the radial stretching of the membrane and thereby permitting the membrane to be utilized a greater number of times before it must be replaced due to) overstretching.
  • the machine has aplurality of shaper units and each shaper unit includes a support for a can body, a tool pack aligned with the support, and a mold assembly with the mold assembly interlocking with the tool pack and the support member whereby the mold assembly resists both radial and axial stresses which occur during the pressurization of the membrane.
  • the mold assembly includes mold halves mounted within mold housing halves for limited axial movement and wherein the mold halves are normally spaced from the support member and are movable in advance of the shaping of a can body to clamp the can body against the support member whereby the can body is axially fixed during the shaping thereof.
  • the shaping units are mounted on a frame for rotation along a predetermined circular path. It is, therefore, necessary to transfer can bodies to and from the support members while the support members are moving in a circular path. If one utilizes a conventional turret for such transfer, the path of the turret coincides with the path of the support members only at a single point. This is insufficient for an accurate transfer. Accordingly, a feature of this invention is the provision of a novel transfer mechanism which, while it moves in a generally circular path, has means for varying the shape of the path so that the path of a can body carried'by the transfer device coincides with the path of the support members for a relatively great extent'so that proper transfer of can bodies from the transfer device to the support members is assured.
  • the support members for receiving can bodies are in the form of chucks which are telescoped within the can bodies in interlocking engagement therewith so that the can bodies may freely rotate with the support member and may be moved'axially with the support members into telescoped engagement over the tool packs.
  • Still another feature of the invention is the provision of drive means for rotating the support members as the support members move axially with can bodies thereon, and there being brake means associated with the drive means for stopping the rotation of the support members, the brake means having associated therewith control means for operating the same with the control means being of the indicia identifying type for stopping the rotation of, the support members with can bodies thereon oriented in a predetermined relationship.
  • a final feature of the invention is the provision of a drive and brake assembly for the machine wherein the machine is provided with a ring gear through which the machine is driven to rotate the same, and the brake means are in the form of clamping type brake elements which engage the ring gear in the manner of disc brakes so as to effect the stopping of the rotation of the machine frame without imparting undesirable stopping forces on the teeth of the ring gear and a drive gear associated therewith.

It is to be noted that the end wall 162 of the membrane 155 is initially spaced from the body support 113. By providing for this longitudinal or axial elongation of the membrane 155, and by utilizing the perforated sleeve 163 to equally distribute fluid within the membrane, it has been found that the life of the membrane can be greatly extended. That is, it may be expanded a very large number of times before it has stretched to the point thatit cannot be readily received within a can body in the automatic operation of the machine 30.
  • the membrane 155 will have to be periodically replaced at relatively short intervals, that is as a matter of days, as opposed to a matter of weeks or months in view of the large capacity of the machine 30.
  • the entire tool pack 43 is readily removable. All that is required to remove the tool pack 43 once the mold unit 42 is open is to disconnect thequick disconnect couplers 154 and 171 and to remove the clamping half 118 of the boss 117. With the entire tool pack 143 thus removed, the membrane 115 may be readily replaced. Under the normal operation of the machine 130, there will be an extra supply of the tool packs 43 so that too] packs 43 with new membranes 155 thereon will be readily available for replacement of the tool packs which have been operated on the machine.
  • Fluid is now supplied to the tool pack 43 through th fitting 152 with fluid flowing into the cylinder 142.
  • This results in a reaction as between the walls of the cylinder 142 and the piston 140 with the result that the reaction ring 128 moves upwardly drawing therewith the cylinder 134 so that the cylinder becomes interlocked and is restrained against axial movement by the mold housing halves 54,55, the mold housing halves 54,55 moving upwardly slightly so as to assure an engagement thereof with the underside of the platen 115.
  • the piston 140 moves downwardly, moving downwardly therewith the extension 150 which engages theextension 148 of each mold segment 105 and forces the mold segments 105 downwardly so as to clamp the flange F of the can body C against the platen 115.
  • the can body C is now ready to be shaped in accordance with the configuration of the mold segments 105.

  • the can body will be slightly foreshortened. However, since the can body is free to move vertically in guided relation with respect to the extension of the collar 157, no problem is involved in this movement.
