Definitions

  • a feature of the construction is that the housing encloses a cylindrical member which is axially slotted so as to form a plurality of circumferentially arranged segments which carry roller elements or disks which are arranged to engage around the periphery of a cap cover which is to be applied to a container by the chucking head.
  • each of the segments is provided with a recess having slots to accommodate axles for roller elements which are disposed in the recesses and retained therein by a retaining ring which is secured to the bottom of the housing.
  • the roller elements are then disposed around a circle of a diameter comparable to the diameter of a cap which is to be applied to a container.
  • the rollers are biased by a rubber sleeve which is fitted around the cylindrical member and preferably with the addition of a resilient holding ring at the exterior of the rubber sleeve.
  • the chucking head includes a resiliently mounted disk at its interior which is displaced inwardly against a resilient biasing force when the cover is received in the head.
  • the rollers are arranged so that when operating they roll over the sidewalls of the cover and will not damage the cover with respect to any painting or printing thereon.
  • the rollers may, however, be arranged in accordance with the invention so that they may constrain radially the cover urging its sidewalls against the outside of the containers mouth Wall or its projections.
  • the inventive chuck is particularly applicable for use with a cover having a wall formation formed with a plurality of longitudinally extending ribs around its periphery and having a free end in the shape of a bead or fianging so that said bead may be deformed into a polygonal configuration by the rollers when the cover is applied to a container, and the ribs may come in locally deformed engagement with the bead of the mouth portion of the container.
  • a modification of the invention is shown wherein instead of the rollers, individual balls are rotatably mounted in hemispherical recesses defined in each segment so that a complete rolling action is effected in respect to the chuck and the associated cover which is to be applied to a container.
  • the invention is particularly applicable to the provision of a closure head or chucking device for applying a securing cap or cover to a container having a large opening particularly for containers which are made of a rigid material such as glass, ceramic, plastic or metal.
  • the invention is an improvement over the prior art particularly in the provision of roller elements or rotatable disks which are carried on separated segmental portions of a chuck cylinder or on a resilient retaining ring.
  • the rollers are arranged to roll over the container cap around the side wall periphery thereof without causing any scratching or abrasion of the cap or wearing off of any printed material or paint thereon.
  • roller elements may be of a size and arrangement such that they will constrain a cover of a particular type into a locally deformed shape so that it may engage the bead or beads on the mouth portion of a container.
  • a cover which is applicable for this purpose will be one which has a plurality of longitudinally extending ribs disposed around the periphery thereof so that by the rotatable elements of the new sealing head the ribs may be brought into locally deformed engagement with a peripheric or thread pitch bead on the mouth portion of the containers and without damaging any dope or finish of the exterior of the cover.
  • a chucking device or a chuck head which includes an interior cylindrical member having a plurality of segmental portions which are separated as by slitting of the end of the cylinder and wherein each of the segmental portions carries rotatable roller elements, disks, balls or the like and wherein a container cover is adapted to be received Within the cylinder so that the roller elements will roll over the sidewalls of a cover laid onto a container without causing any damage thereto.
  • a further object of the invention is to provide a chucking head construction which is simple in design, rugged in construction and economical to manufacture.
  • FIG. 1 is a partial sectional and elevational view of a chucking head constructed in accordance with the invention
  • FIG. 2 is a section taken on the line 2-2 of FIG. 1;
  • FIG. 3 is a top plan view of a cover which is applicable for use with a chucking head of the invention
  • FIG. 4 is a sectional view taken along the line 44 of FIG. 3;
  • FIG. 5 is a top plan View of a container indicating the cover which has been applied thereto and which has been locally de-formed by the chucking head of the invention.
  • FIG. 6 is a partial sectional view similar to FIG. 1 of another embodment of the invention.
  • the invention embodied therein comprises a chucking head assembly or head piece generally designated 1 which includes a holder or housing member 20 which closes one end of an outer casing or cylinder 7.
  • the holder 20 is provided with a bore 22 in which is slidable a bolt or retaining member 24.
  • the bolt 24 carries a disk 13 at its outer end which is adapted to engage the top of a cover which is received in the chuck headI
  • a spring (not shown) is engaged with the bolt 24 and urges the bolt together with the disk 13 downwardly toward the open end of the chuck housing member 7 and permits inward movement of the disk when the cap is received in the chuck head 1.
  • a hollow cylinder or chuck ring member 2 is secured to the holder 20 and it is provided with a plurality of segmental portions 2a which are formed at the lower end by axially extending slits 3 which are defined at spaced locations around the periphery thereof.
  • the ring sectors 241 are embraced by a rubber sleeve member 5 which acts as a cushioning element and the assembly is held together by means of a resilient metal ring 6.
  • the ring 6 may be constructed as a tensioning ring and may be adjusted in respect to its width to provide the desired holding force around the exterior of the cylinder 2.
  • the segmental portions 2a are provided with slots 9 which extend upwardly from the bottom thereof and are defined on each side of a recess 26 formed in each segment 2a.
  • the recess 26 is of a size to accommodate a roller element 10 having axles 11 which are rotatably supported in the slots 9. After the rollers 10 are inserted into the recesses 26, they are retained in position by means of a holding ring 12 which is secured to the cylinder 7 such as by bolts 28.
  • the holder 12 is provided with a rounded lip to permit mounting of the rollers so that they will be easily rotatable when the chuck is used.
  • the segments 2a are of a dimension and the rollers 10 are arranged so that they will be spaced substantially evenly around the periphery of a circle which is defined by the periphery of the disk 13 and which conforms to the exterior diameter of the side wall of a cover member to be used with the chuck.
  • a cover which is particularly applicable for use in association with the chucking head 1 is shown and designated by numeral 30.
  • the cover 30 is of substantially cylindrical shape and has a side wall with a plurality of embossed grooves 15 which form inwardly projecting ribs therebetween.
  • the lower portion of the cover is provided with a flanging 16 which in the embodiment illustrated extends outwardly.
  • the cover is laid upon a container mouth and secured by the chucking head which moves downwardly over the top of the cap.
  • the cap causes the displacement of the disk member 13 inwardly as the chucking head 1 descends over the cap.
  • the rollers 10 arranged around the interior of the cylinder 2 in the embodiment illustrated are such that they engage the side walls of the container cover in a rolling-like action without hurting the finish of the walls but they constrain the walls inwardly at the roller areas so that the ribs come in locally deformed engagement with the bead of the container mouth.
  • the flange 16 of the cap will not be afiected by this action except for being brought into a polygonal shape.
