Definitions
- This invention relates to an improved method and apparatus for applying closures to containers and is particularly concerned with the ready conversion of automated bottling operations from the use of one type of closure cap to another.
- containers 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 in 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. Normal maintenance requires occasional repair or placement of these crown applying mechanisms.
- Another object is to provide an improved apparatus for carrying out such novel 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 apparatus for securing crown type closure caps to containers.
- a further object is to provide an improved apparatus for securing tear off type closure caps to containers.
- a more detailed object is to provide improved cap securing mechanisms which are interchangeably mounted at the lower end of a turret housed crowner plunger.

- FIG. 1 there is shown a crowner turret 1 incorporating a set of improved cap applying mechanisms, hereinafter referred to as heads, in accordance with the invention.
- the basic crowner turret is part of 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 ice end by a cap 4 and has circumferentially arranged therewithin a plurality of slideably mounted plunger assemblies 5.
- a fixed center shaft 6 extends through the hollow drive shaft 3 and has secured about the upper portion thereof a circular plate 7 provided with a cam race 8.
- a radially inwardly extending cam follower 9 is mounted at the upper end of each of the plunger assemblies so as to ride within the cam race 8.
- Each of the plunger assemblies 5 includes an outer cylinder sleeve 10 which depends below the turret 1 and surrounds a further downwardly extending work imparting shaft 11.
- a crimping head 20 for applying hand tear off closure caps is threadedly engaged to each of the shafts 11 except shaft 11a which has its head 20 detached in the manner disclosed by this invention for purposes of illustration.
- 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 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 20 secured to the lower end thereof seal a cap 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 20 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 heads for interchangeable attachment to the work imparting shafts 11 at the lower end of the plunger assemblies 5.
- the application of hand tear off caps is effected by threaded engagement of the crimping heads 20 as illustrated in FIG. 2, to the shafts 11.
- Subsequent conversion to the application of standard crowns is effected by simply detaching the crimping heads 20 and substituting crowner heads generally indicated at 290 in FIG. 3.
