Definitions

  • This invention relates to an improved method and apparatus for applying closures to containers and is particularly concerned with high speed bottle capping equipment which can be quickly converted for applying dilferent types of closures.
  • conainers are filled and capped or crowned in a continuous operation performed by a single piece of equipment called the filler which includes a crowner as an integral part thereof.
  • the filler which includes a crowner as an integral part thereof.
  • Illustrative of conventional equipment of this general type is that manufactured and sold by the Crown Cork and Seal Company under the Cemco trade name.
  • the bottles or other containers after having been filled are conveyed by a star wheel underneath a crowner turret within which a plurality of crowner plunger assemblies, each incorporating a crown applying mechanism at the lower end thereof, is slideably mounted to effect the capping operation.
  • This invention greatly simplifies the initial change over from a standard crowning operation to the application of convenience closures and the subsequent conversion back and forth from one to the other in that no modification of the existing parts is necessary. A very minor disassembly step is all that is required.
  • Another object is to provide an improved apparatus for carrying out such method.
  • Another object is to provide an improved method and apparatus for the conversion of bottle capping operations from the application of one type of closure cap to another.
  • a further object is to provide an improved method and apparatus for applying either fluted skirt crown caps or smooth skirt tear off closures to bottles by means of the same basic equipment.
  • a further object is to provide an improved apparatus for crimping tear off type closure caps onto container necks.
  • a more detailed object is to effect the operation of a segmented crimping annulus through the actuation of a partially disassembled crowning mechanism.
  • FIG. 1 is a vertical elevation of a crowner turret partially broken away for clarity and incorporating tear off type closure applying heads in accordance with the invention
  • FIG. 2 is a perspective view of a tear off type closure applying head
  • FIG. 3 is a perspective view of a crowner platform and throat assembly
  • FIG. 4 is a vertical section of the complete crown applying mechanism and showing a bottle in crowning position

  • FIG. 8 is a bottom plan of the tear off type closure applying head of FIG. 7;
  • FIG. 9 is a elevational view of the tear off type closure applying head of FIG. 7 but in detached condition.
  • FIG. 10 is a fragmentary sectional View showing the relationship of certain parts in crimping position.
  • FIG. 1 there is shown a crowner turret 1 incorporating a set of tear off type closure applying heads 50, in accordance with the invention.
  • the basic crowner turret 1 is part of a standard filling equipment employed in high speed bottling operations such as manufactured by the Crown Cork and Seal Company under the Cemco trade name and is seen to comprise a generally cylindrical housing 2 mounted on a central hollow drive shaft 3.
  • the turret 1 is closed at its upper end by a cap 4 and has circumferentially arranged therewithin a plurality of plunger assemblies 5 mounted for vertical reciprocating movement within the turret 1.
  • a fixed center shaft 6 extends through the hollow drive shaft 3 and has a circular disc 7 provided with a cam race 8 secured about the upper portion thereof.
  • a radially inwardly extending cam follower 9 is mounted at the upper end of each of the plunger assemblies '5 so as to ride within the cam race 8.
  • Each of the plunger assemblies 5 includes an outer cylinder sleeve 10 which surrounds a work imparting shaft 11.
  • a crimping head 50 for applying hand tear off convenience closures is secured to each of the shafts 11 except shaft 11a which has its head 50 detached for purposes of illustration in the manner disclosed by this invention.
  • a bottle feed star wheel 12 Positioned below the turret 1 and rotatable therewith.
  • the bottles are fed in a circular path underneath each plunger assembly of the capping turret 1 by the star wheel 12 and as the cam followers 9 ride down the cam race 8 the plunger assemblies 5 are progressively lowered so that the crimping heads 50 secured to the lower ends thereof seal a closure onto each bottle as rotational movement of the turret and star wheel continues.
  • the cam follower Upon reaching the lowest point in the cam race 8 the cam follower then moves upwardly again to its initial position thus releasing the crimping head 50 from the bottle whereupon the capped bottle is conveyed by other suitable means (not shown) away from the star wheel 12.
  • FIGS. 2 and 3 illustrate the two different cap applying mechanisms for interchangeable attachment to the work imparting shafts 11 at the lower end of the plunger assemblies 5.
  • the application of conventional crown caps is effected by engagement of the crowner throat and platform assembly generally indicated at 90, as illustrated in FIG. 3, to the shafts 11.
  • Subsequent conversion to the application of tear off closures is effected by simply detaching the crowner assembly 90 and substituting the crimping heads generally indicated at 50 in FIG. 2.
  • FIGS. 4, 5 and 6 wherein it is seen that the work imparting shaft 11 extends downwardly beyond the cylinder of the plunger assembly 5 and is retained therein by an externally threaded outer bushing 12 provided with a circumferential flange 13 at its lowermost end which bears against the lower end of the sleeve 10.
  • the shaft 11 has a circumferentially enlarged central section 14 which rests against the upper end of the bushing 12.

  • the plunger assembly 5 is then lowered with respect to a bottle 41.
  • the undersurface of the crown cap 50 contacts the bottle 41 and is compressed thereagainst the spindle 24 becomes stationary while the shaft 11 continues to move the crowner throat 31 downwardly against the resistance of compression spring 26.
  • the relative movement between the plunger 24 and the crowner throat 31 causes the throat inner surface 32 to engage the fluted crown cap skirt and push it in under the lip of the bottle 41.
  • the axial extent of this movement is controlled by adjustment of the stud 18. Upward movement of the plunger assembly 5 by movement of the cam follower 9 along the cam race 8 restores the parts to their initial position as shown in FIG. 4.
  • FIG. 6 illustrates the partial disassembly of the crowning mechanism whereby the crowner platform and throat assembly 30 is easily detached from the work shaft 11 through removal of the three screws 35. This step is all that is required to prepare the crowner plunger assembly 5 for conversion of the application of tear off closures.
