Abstract

A cantilever carousel system for efficiently storing multiple print cylinders while providing a common access point for loading and unloading the print cylinders. The cantilever carousel system generally includes an external frame structure defining an internal cavity and a shell connected to the external frame structure to surround the cavity, wherein the shell includes at least one access opening extending therethrough. An internal frame structure is positioned within the cavity and a vertically oriented carousel is supported by the internal frame structure. A drive assembly is mechanically connected to the carousel, wherein the drive assembly circulates the carousel and a plurality of cantilever mandrels are supported by the carousel and circulate with the carousel. A plurality of print cylinders are removably received by the plurality of cantilever mandrels through the access opening.

Dependent claims

A cantilever apparatus for removably supporting a tubular object, comprising:

a cantilever having an inner end and an outer end, wherein said cantilever is adapted to removably receive a tubular object;
an end member extending outwardly from said outer end of said cantilever, wherein said end member includes a distal end portion;
wherein said end member is comprised of a shaft member extending outwardly from said outer end of said cantilever and wherein said distal end portion is comprised of a head member;
and
a stop member having a connecting aperture, wherein said connecting aperture is comprised of a lower portion and an upper portion, wherein a width of said lower portion is greater than a width of said upper portion, and wherein said lower portion of said connecting aperture has a size greater than said distal end portion of said end member to allow said connecting aperture to pass over said distal end portion of said end member;
wherein said cantilever is supported upon a carousel, wherein said carousel circulates said cantilever along a first vertical run and a second vertical run, wherein said first vertical run moves downwardly when said second vertical run moves upwardly, wherein said first vertical run and said second vertical run are parallel with respect to one another, wherein said first vertical run extends along a first vertically orientated plane, and wherein said second vertical run extends along a second vertically orientated plane.

A cantilever apparatus for removably supporting a tubular object, comprising:

a cantilever having an inner end and an outer end, wherein said cantilever is comprised of an elongated structure having a longitudinal axis, wherein said cantilever is adapted to removably receive a tubular object and wherein said tubular object is comprised of a print cylinder;
an end member extending outwardly from said outer end of said cantilever;
and
a stop member having a connecting aperture, wherein said connecting aperture has at least a portion having a size greater than a distal end portion of said end member to allow said connecting aperture to pass over said distal end portion of said end member;
wherein said end member is comprised of a shaft member extending outwardly from said outer end of said cantilever and wherein said distal end portion is comprised of a head member;
wherein said stop member rotates upon said shaft member;
wherein said head member has a cross sectional size greater than said shaft member;
wherein said connecting aperture is comprised of a lower portion and an upper portion, wherein a width of said lower portion is greater than a width of said upper portion;
wherein said width of said lower portion of said connecting aperture is greater than a width of said head member;
wherein said width of said upper portion of said connecting aperture is smaller than said width of said head member and larger than a width of said shaft member;
wherein said cantilever is supported upon a carousel, wherein said carousel circulates said cantilever along a first vertical run and a second vertical run, wherein said first vertical run moves downwardly when said second vertical run moves upwardly, wherein said first vertical run and said second vertical run are parallel with respect to one another, wherein said first vertical run extends along a first vertically orientated plane, and wherein said second vertical run extends along a second vertically orientated plane.

A cantilever apparatus for removably supporting a tubular object, comprising:

a cantilever having an inner end and an outer end, wherein said cantilever is comprised of an elongated structure having a longitudinal axis, wherein said cantilever is adapted to removably receive a tubular object and wherein said tubular object is comprised of a print cylinder;
wherein said cantilever is supported upon a carousel, wherein said carousel circulates said cantilever along a first vertical run and a second vertical run, wherein said first vertical run moves downwardly when said second vertical run moves upwardly, wherein said first vertical run and said second vertical run are parallel with respect to one another, wherein said first vertical run extends along a first vertically orientated plane, and wherein said second vertical run extends along a second vertically orientated plane;
an end member extending outwardly from said outer end of said cantilever, wherein said end member is concentrically attached to said cantilever;
and
a stop member having a connecting aperture, wherein said connecting aperture has at least a portion having a size greater than a distal end portion of said end member to allow said connecting aperture to pass over said distal end portion of said end member;
wherein said end member is comprised of a shaft member extending outwardly from said outer end of said cantilever and wherein said distal end portion is comprised of a head member;
wherein said stop member rotates upon said shaft member and wherein said stop member is adapted to remain substantially vertically aligned regardless of the rotational position of said cantilever;
wherein said head member has a cross sectional size greater than said shaft member;
wherein said connecting aperture is comprised of a lower portion and an upper portion, wherein a width of said lower portion is greater than a width of said upper portion;
wherein said width of said lower portion of said connecting aperture is greater than a width of said head member;
wherein said width of said upper portion of said connecting aperture is smaller than said width of said head member and larger than a width of said shaft member;
wherein said shaft member and said head member each have a circular cross sectional shape;
wherein said shaft member has a diameter that is smaller than a diameter of said head member;
wherein said head member has a diameter that is at least twenty-five percent greater than a diameter of said shaft member;
wherein said stop member is comprised of an upper segment that extends above an upper surface of said cantilever;
wherein said stop member is comprised of a lower segment that extends downwardly from said upper segment;
wherein said connecting aperture is positioned between said lower segment and said upper segment, wherein a weight of said lower segment is greater than a weight of said upper segment to maintain said stop member in a substantially vertically aligned position with said upper segment extending upwardly.
