  • crown head assembly 10 includes an adapter 42 for connecting the head assembly to spindle sleeve 12 so that the sleeve can freely rotate in the head assembly without rotating the assembly.
  • an adapter 42 for connecting the head assembly to spindle sleeve 12 so that the sleeve can freely rotate in the head assembly without rotating the assembly.
  • Adapter 42 includes a mounting sleeve 44 which may be secured on spindle sleeve 12 by means of threads, keys or the like, a bearing assembly 46 for rotatably connecting the mounting sleeve and head body 16, and a spanner plate 48 which provides means for turning the mounting sleeve to screw it on or off the spindle sleeve.
  • Bearing assembly 46 includes the necessary ball bearings and raceways for providing a rotatable connection between mounting sleeve 44 and head body 16 and is secured between such mounting sleeve and head body by means of retaining rings 50 and 52.
  • Bearing assembly 46 is particularly adapted for accommodating relative rotational movement between mounting sleeve 44 and head body 16 while transmitting axial or vertical movement or travel. Consequently, when a crown cap applying head assembly is secured on a spindle 12,
  • FIG. 5 shows that head body 16 of a crown head assembly 10 may be adapted for sliding contact against the head body of adjacent crown head assemblies in a turret assembly to prevent the assemblies from rotating, but not to interfere with relative vertical travel of the adjacent assemblies.
  • Corresponding edge surfaces of crown platforms 28 preferably have a small clearance therebetween, and are not used to prevent rotation of head assemblies 10.
  • lateral edge surfaces on each head assembly preferably have an included angle therebetween which corresponds to the angle of the arc in the periphery of the turret assembly which is occupied by each such head (FIG. 2). Consequently, the contacting lateral edge surfaces on adjacent head bodies 16 are substantially parallel and slide against one another to prevent rotation of the head assemblies on their respective spindles.
  • FIG. 2 shows magnet assemblies 58 in capping head 10 including a magnet 59 in each assembly for holding a steel crown cap in position in the assembly for application to a container.
  • Platform 28 has a slot in the side thereof which faces outwardly in a turret assembly for receiving a cap 20 for application to a container.

  • Turret assembly 60 may comprise a center post 72, a turret hub 74, a turret frame 76 with a plurality of outwardly open vertical slots around its circumference in which spindles can be mounted, a lower cam 78, an upper cam 80, a turret support sleeve 82, a drive gear 84, an upper cam support 86 and a nut 88.
  • Each spindle 14 may comprise a support yoke 90 resiliently mounted on a shaft 36 by means of a coil spring 94 and a housing 96, with a cam follower 98 secured to the top of the yoke.
  • Cam follower 98 is disposed in a cam track 100 in upper cam 80 and follows the up and down path of the track to move yoke 90 up and down as spindle 14 is rotated around the turret and the stationary cam track.
  • coil spring 94 is supported on housing 96 which is rigidly attached to shaft 36.
  • a nut 102 is threaded on the end of housing 96 to secure yoke 90 thereon, and a nut 104 is threaded on the end of the shaft 36 so that vertical movement of the yoke resiliently acts on the shaft with compression of the spring moving the upper end of the shaft upward through the open center of the yoke.
  • Spindle 14 further includes a drive sleeve 12 with a gear 108 secured thereto mounted on head pressure shaft 36 below housing 96 so that the collar and gear can freely rotate on shaft 36, and a slide 110 over drive sleeve 12 with a cam follower 112 attached to the upper end of the slide and a cone cam 111 attached to the bottom of the slide for camming rollers on headset 62 inwardly against a closure skirt.
  • gear 108 is continually rotated by drive gear 84, which in turn rotates drive sleeve 12.
  • drive gear 84 which in turn rotates drive sleeve 12.
  • rotation of the drive sleeve rotates the headset to roll threads in the skirt of a closure to affix such a closure on'a container.
  • headset 62 selected for illustration is conventional and need not be described in detail.
  • headset 62 comprises a head body 114, at least one thread roller 116, at least one band roller 118, cam rollers for rotating the thread and band rollers, and a system of springs, roller arms, and pivot shafts for moving the thread and band rollers inwardly against a closure skirt and rotating such rollers around the axis of the spindle.
  • Such rotation of headset 62 reforms the skirt of roll-on closure 122 against the mouth of a bottle 124 to secure the closure on the bottle.
  • FIGS. 4 and 5 illustrate crown cap applying heads 10 mounted on spindles 14 in a turret assembly 60 in accordance with the invention.
  • Turret assembly 60 is substantially identical to the prior art turret-assembly illustrated in FIG. 3 except that it has crown cap applying heads mounted on the spindle 14, and may include means, not shown, for feeding crown closures into the heads for application to bottles or other containers 24.
  • the spinning headsets have been removed from each of the spindles 14 in turret assembly 60, along with cone cam 111 from slide 110 (FIG. 3), and a crown cap applying head has been mounted on each such spindle.
  • crown caps made of steel can be fed into crown platform 28 on each head assembly and into position in the slot in such platform. Magnets 59 in such platform hold the steel crown caps in position on such platform until they are applied to containers.
  • Upper cam track 100 in cam member 80 moves cam follower 98 which is attached to the upper end of spindle l4 downwardly with the spindle andhead assembly 10 mounted thereon to lower crown closure 20 onto bottle 24 and apply top pressure against the closure on the bottle.
  • bottle 24 with closure 20 thereon resists further downward travel of knock-out plunger 30 so that spring 32 is compressed.
  • Adapter 42 in head assemblies 10 permits drive sleeve 12 to freely rotate within such head assemblies, and the flat lateral edges of each head assembly 10 engages the flat edge surfaces of adjacent head assemblies to prevent rotation of such assemblies. The head assemblies will therefore be moved vertically by drive sleeve 12 to apply crown closures to bottles but will not rotate.
  • Lower cam track 101 in lower cam 78 also moves lower cam follower I 12 up and down as spindles 14 are rotated around the turret assembly 60, but such vertical travel has no effect on the crown cap applying heads capping machine 60 can be operated to apply roll-on closures to bottles in a manner which is known.
  • this invention provides a swage-on cap applying head which can be mounted on a spindle in a rotating turret assembly which is normally used for the application of roll-on closures to bottles.
  • a swage-on cap applying head of the invention may be mounted in a capping machine having only one stationary spindle mounted therein for applying closures to container.
  • the capping head may also be mounted on turrets which have vertical bores therein for receiving spindles rather than outwardly open guideways as in the turret assembly selected for illustration.
