Definitions

  • a bottle guide and ear wiping device is provided whereby a cap tearing ear is precisely positioned adjacent to the neck of the bottle as a plurality of crimping jaws form the cap skirt in tightly underneath the lip of the bottle.
  • This invention relates to apparatus for securing container closures and is particularly concerned with an improved apparatus for crimping lightweight metal closure caps onto container necks.
  • the improved crimping head of this invention provides for the high speed capping of bottles or other containers despite the inherent dimensional variations in such containers and the relatively inaccurate positioning of hottle feeding mechanisms.
  • closure caps of the type having an outwardly extending gripping ear to facilitate removal by tearing is the provision of means for wiping the ear down against the container neck as the cap is secured.
  • the closed the ear is wiped down onto the container neck the less chance there is of the seal being inadvertently broken through interference with the car during subsequent handling of the container.
  • the ear is wiped down too far and forcibly pressed against the container by the crimping head the likelihood of damaging or completely destroying the container is great.
  • the problem then is to wipe the ear down as close as possible to the container neck during the cap applying operation without actually striking the container.
  • inherent dimensional variations in the shape and height of the bottles or other containers being capped with prior art constructions has made it difficult, if not impossible, to perform this wiping operation with the desired precision.
  • Both of the above described container guiding and ear wiping functions are advantageously performed by the improved crimping head of this invention in a simple and unique manner. More specifically these two functions are advantageously performed by a single element and its mounting. Furthermore the required precision has been achieved while accommodating normal variations in containers and in the equipment feeding such containers.
  • Another object is to provide closure cap crimping apparatus having improved guide means for positioning container necks in proper axial alignment for the crimping operation.
  • a further object is to provide crimping apparatus for applying closure caps formed with outwardly extending tearing ears having improved means for wiping such ears against the container neck.
  • a still further object is to provide closure cap crimping apparatus wherein said improved guide and wiping means are one and the same.
  • a more detailed object is to provide closure cap crimping apparatus wherein said guide and wiping means is operative in predetermined vertically spaced relationship to the crimping jaws.
  • FIG. 1 is a vertical section of the cap securing head and associated workpiece showing the crimping jaws in open or expanded position and with the guiding and wiping ring is raised position;
  • FIG. 2 is a bottom plan of the cap securing head alone taken on line 22 of FIG. 1 and looking in the direction of the arrows;
  • FIG. 3 is a vertical elevational view of the crimping head having a portion cut away and showing the jaws in closed or crimping position and the guiding and wiping ring in final operative position;
  • FIG. 4 is a perspective view of the guiding and wiping ring and retainer plate therefore with a section cut away to show the contour of the ring working surface;
  • FIG. 5 is an enlarged fragmentary section of the parts indicated by the circle in FIG. 1.
  • the crimping head assembly herein shown and described is adapted for use either in conjunction with standard bottle filling lines to replace the normal crowners in the crowner head casing such as manufactured by the Crown Cork and Seal Company under the trade name Cemco or in a hand actuated device of the type also manufactured under the Cemco trade name.
  • the crimping head is carried by a hollow shaft 1 which is mounted in the standard crowner head casing.
  • the lower end of the shaft 1 is integrally and radially outwardly enlarged into an annular portion 2 having a diameter greater than the diameter of the remainder of the shaft 1.
  • a bore 3 formed in the shaft is threaded at 4 to receive the threaded portion of a sleeve 5.
  • a circumferential flange 5a around the lower end of sleeve 5 engages the lower end of the shaft 1 when the sleeve 5 is fully seated within the shaft.
  • a spindle 6 Slideably received within the sleeve 5 is a spindle 6 having at its upper end an internally threaded bore 7 which receives the lower threaded end of a connecting member 8.
  • a collar 9 is formed about the center portion of the connecting member 8 with the upper end thereof terminating in a shank 10.
  • a pin 11 locks the connecting member 8 and the spindle 6 together. This pin is accessible through the shaft 1 and sleeve by means of the passages 12 closed by the threaded plugs 13.
  • a helical compression spring 14 Surrounding the shank is a helical compression spring 14 extending between the collar 9 and the upper end wall 15 of the bore 3 and adapted to be compressed therebetween and to normally retain the collar 9 in contact with the inner end of sleeve 5.
  • the lower end of the spindle 6 is provided with an internal bore 16 extending downwardly and terminating at its lower free end in a cap receiving nest 17 having a downwardly extending side wall 17a.
  • An outwardly extending collar 18 is fitted about the wall of the spindle 6 opposite the upper part of the bore 16 being positioned vertically by seating on the annular shoulder 19 formed outwardly on the spindle 6.
  • a cap hold down member con sisting of a sleeve 20 having an upper end 21 of enlarged outside diameter is slideably received within the bore 16.
  • the lower portion of the sleeve 20 has an end wall 22 which supports on its inner surface the lower end of compression spring 23. The outer surface of the end wall 22 contacts the top of the cap 24 upon downward movement of the head.
  • the upper end of spring 23 engages the upper end wall 25 of the bore 16.
  • the sleeve 20 is slideably retained within the bore 16 by means of a pair of pins 26 which are seated in bores 27 extending horizontally through the lower cylindrical wall of the spindle 6.
  • Each of said bores 27 is so positioned that only half of its diameter extends into surface of bore 16, the other half underlies the enlarged collar 21 of the sleeve 20.
  • the pins 26 thus retain the sleeve 20 in place in the bore 16 while allowing rertical reciprocation of the sleeve.
  • the periphery of the collar 18 has an arcuate convex contour upon which is pivotally mounted mating concave surfaces 28 formed in the upper ends of a plurality of annularly arranged sealing members or jaws 29.
  • the jaws 29 are of identical construction and in this embodiment are twelve in number spaced about the cap receiving nest 17. The number of jaws may of course be varied without departing from the scope of the invention.
  • Each jaw has formed at its upper end a radially outwardly extending protuberance 30 which slidably contacts the inner surface of the adjacent segment 34, described hereinafter, and serves to retain the upper end of the jaw in pivotal engagement with the collar 18.
  • Each jaw at its lower end is formed with a radially inwardly facing crimping or sealing surface 31 having a convexly curved configuration.
  • the outer end portion of each jaw is formed with an inclined cam surface 32.
  • a segmental closing ring or sleeve generally indicated at 33 is provided for closing the jaws 29 and their crimping surfaces 31 about the bottle finish.
  • the ring 33 is formed of a plurality of individual arcuately shaped segments 34 of equal dimension. Six of these segments are shown, that is, each segment 34 actuates two of the jaws 29 by engaging the jaw cam surfaces 32. Here again the number of segments may be varied without departing from the scope of the invention.
  • the upper end of each segment 34 inclines inwardly into a segmental collar portion 35 having an outwardly facing convex arcuate periphery which mates with a concave channel 37 formed into the interior surface of the enlarged annular portion 2.
  • each segment 34 is retained in mated and pivotal relationship with the concave channel 37 by the abutment of the outwardly extending flange 5a at the lower end of the sleeve 5 with the inner end surfaces of the collar portions 35.
  • the lower end of each segment 34 is enlarged radially outwardly and provided with inwardly facing cam surfaces 38 for coaction with the cam surfaces 32 of the jaws 29.
  • Extending radially inwardly from the interior of each segment 34 is a center wedge shaped partition 39 and two wedge shaped side partitions 40 each eing of half the width of he center par i n 39 4 as best seen in FIG. 2. These partitions 39 and 40 provide slideways to guide the jaws 29 in their movement between open and closed position.
  • An annulus 41 of resilient material is mounted about the lower portion of the spindle 6 and has a radially outwardly extending flexible collar 42 of reduced thickness which engages the interiors of the jaws 29 and continuously resiliently urges those jaws outwardly so that the jaw cam surfaces 32 are held in contact with their mated cam surfaces 38 on the segments 34.
  • the segments 34 forming ring 33 are resiliently restrained from pivotal outward movement away from the jaws 29 by means of an annular spring collar 43 which overlies and encircles the greater portion of the segments 34.
  • the spring collar 43 has a solid upper portion 43a from which a plurality of downwarlly extending resilient fingers 44 extend as clearly seen in FIG. 3. These fingers 44 having radially inwardly extending ledges at their lower ends terminating in surfaces 46 which contact the outer surface of the segments 34 so that the fingers 44 resiliently restrain the segments 34 against excessive radial outward movement.
  • a locking screw 45 inserted between two of the fingers 44 into a tapped hole in one of the segments 34 prevents circumferential movement of the spring collar 43.
  • An annular retainer plate 47 is floatingly mounted on the lower end of the segments 34.
  • the floating mounting is effected by a pair of elongated openings 48 provided in the plate 47 for the reception of screws 49 which are threadedly engaged with the segments 34.
  • the elongated openings 48 open downwardly into elongated counterbores 49a to accommodate a screw adaptor 50 seated over the screws 49 and having head portions 51 loosely seated in the counterbore 49 and shanks 50 loosely seated in the opening 48 as seen in FIG. 5.
  • a resilient washer 52 is interposed between the adaptor head 51 and the bottom 53 of the counterbore 49.
  • a combination bottle guide and gripping ear wiper generally in the form of an annulus is in turn floatingly retained Within the opening in plate 47.
  • This combination member comprises a ring 53 having a flat upper surface 54 and an under conical working surface 55 inclining upwardly in its inward extent.
  • Four radial supporting lugs '56 having upper surfaces forming continuations of the surface 54 seat loosely in slots 57 in the upper surface of the retainer plate 47 when the crimping head is raised and the jaws 29 are in open position thus holding the ring 53 closely adjacent the lowermost ends of the jaws 29 as shown in FIG. 1.
  • the rounded crimping surfaces 31 extend radially inwardly of the innermost edge 55a of the conical surface 55 so that the last increment of bottle guiding is performed by the jaws themselves.
  • the sidewall 17a of the cap receiving nest 17 is in substantially vertical alignment with the conical surface edge 55a.
  • the ring 53 and retainer plate 47 are carried downwardly by the crimping head causing the conical surface 55 to strike the cap -gripping ear 59. Continued downward movement pushes or deflects the car down against the container Wall until the cap receiving nest 17 becomes properly seated on the cap and the camming action of the segments 34 commences.
  • the car 59 Upon completion of the crimping action the car 59 is wiped down closely adjacent the neck of the bottle so that the capped bottle may be subsequently handled without interference with the ear.
  • the accuracy with which the ear 59 is wiped down to its desired position adjacent the bottle neck is always maintained at a constant since the axial movement of the ring 53 is dependent solely on the axial movement of the jaws 29. Regardless of the amount of downward travel of the segments 34, and end plate 47,
  • the ear 59 is always wiped down to precisely the same position relative to the bottle finish, closely adjacent the bottle neck.
  • To wipe the ear down in accordance with known constructions, short of that precise position adjacent the bottle neck presents the possibility of interference with the ear and even destruction of the seal during subsequent bottle handling operations, which on the other hand, to wipe the ear down much beyond the desired position usually results in a broken bottle.
  • Retraction of the crimping head after completion of the crimping operation restores the respective elements to the position illustrated in FIG. 1 with the jaws 34 being urged radially outwardly by the flexible collar 42 of the annulus 41.
  • the cap applying apparatus of this invention substantially improves upon prior art cap crimping arrangements and greatly enhances the etficiency of such high-speed bottling operations.
  • Apparatus for securing a closure cap to a neck bordering the opening of a container comprising an axially movable mounting member, a plurality of circum-ferentially arranged elongated sealing members pivotally connected to said mounting member and depending therebelow, actuating means movable relative to said sealing members surrounding said sealing members for swinging said sealing members radially inwardly along an arcuate path into a contracted position to form a complete sealing annulus, and a continuous annular working surface adapted for coaction with a container neck and unsecured closure cap loosely applied thereto, said working surface lying in concentric axial alignment with said sealing members and positioned axially in predetermined vertically spaced relationship below said sealing members during said axial and radial movement.
  • Apparatus as in claim 1 including a downwardly opening cap receiving nest positoned at the lower end of said mounting member said nest having a top wall and a side wall and said working surface having a minimum internal diameter in substantially vertical alignment with the internal diameter of said side wall.
  • said working surface comprises a radially inwardly and downwardly facing conical surface formed on a ring member mounted in concentric axial alignment below said sealing means.
  • Apparatus for securing a closure cap having a radially extending gripping ear to a neck bordering the opening of a container comprising an axially movable mounting member, a plurality of circumferentially arranged elongated sealing members operatively connected to said mounting member and depending therebelow, actuating means surrounding said sealing members for swinging said sealing members radially inwardly into a contracted position to form a complete sealing annulus, and a continuous annular working surface adapted for coaction with a container neck and unsecured closure cap loosely applied thereto, said working surface lying in concentric axial alignment with said sealing members and positioned axially in predetermined vertically spaced relationship below said sealing members during said axial and radial movement whereby said working surface deflects said gripping ear downwardly to a position closely adjacent said container during said axial movement.
  • Apparatus for securing a closure cap to a neck bordering the opening of a container comprising an axially movable mounting member, a plurality of circumferentially arranged elongated sealing members operatively connected to said mounting member and depending therebelow, actuating means including an axially movable camming sleeve for coaction with the lower outer end portion of said sealing members, said camming sleeve surrounding said sealing members for swinging said sealing members radially inwardly into a contracted position to form a complete sealing annulus, a retainer plate movably mounted at the lowermost end of said camming sleeve, a continuous annular working surface adapted for coaction with a container neck and unsecured closure cap loosely applied thereto, said working surface lying in concentric axial alignment with said sealing members and positioned axially in predetermined vertically spaced relationship below said sealing members during said axial and radial movement and said working surface being freely vertically supported on said retainer plate whereby vertical
