Abstract

An alignment assembly for a press assembly is provided. The alignment assembly includes a number of alignment elements. The alignment elements include a number of moving alignment elements. The moving alignment elements are coupled to an upper tooling assembly that moves between a first and second position. As the upper tooling assembly moves, the moving alignment elements move between a first position and a second position corresponding to the upper tooling assembly first position and a second position. The moving alignment elements are structured to move the shell from the initial alignment position to an intermediate alignment position. Thus, as the upper tooling assembly moves from the first position to the second position, the moving alignment elements contact a shell and move the shell from an initial alignment position to an intermediate alignment position.

First claim

What is claimed is:

1. An alignment assembly for a press assembly, said press assembly including a transfer belt and a tooling assembly, said tooling assembly including an upper tooling assembly and a lower tooling assembly, said upper tooling assembly moving between a first position, wherein said upper tooling assembly is spaced from said lower tooling assembly, and a second position, wherein said upper tooling assembly is immediately adjacent said lower tooling assembly, said transfer belt including a number of apertures, each said aperture generally corresponding to a shell, said transfer belt positioning said shells in an initial alignment position, said alignment assembly comprising:
a number of moving alignment elements;
said moving alignment elements configured to be coupled to said upper tooling;
wherein said moving alignment elements are structured to move said shell from said initial alignment position to an intermediate alignment position;
each said moving alignment element includes an elongated body with a first end and a second end;
wherein the second end of said elongated body of each said moving alignment element includes an angled surface;
said number of alignment elements include a number of alignment recesses configured to be disposed in said transfer belt about the perimeter of each said belt aperture; and
each said alignment recess is structured to align with an associated moving alignment element to allow said moving alignment element to pass through said transfer belt.

2. The alignment assembly of claim 1 wherein each said shell includes a first axis and a second axis, wherein each said shell first axis and each said shell second axis are generally perpendicular to each other, and wherein:
said number of alignment elements includes a first alignment element and a second alignment element; and
wherein said first alignment element and said second alignment element are disposed generally opposite each other and on opposite sides of one of said shell first axis or said shell second axis.

3. The alignment assembly of claim 2 wherein:
said number of alignment elements includes a third alignment element and a fourth alignment element; and
wherein said third alignment element and said fourth alignment element are disposed generally opposite each other and on opposite sides of one of said shell first axis or said shell second axis.

4. The alignment assembly of claim 1 wherein each said shell includes a first axis and a second axis, and wherein:
each said shell is generally planar and has a generally rectangular shape;
said number of alignment elements includes a first alignment element, a second alignment element, a third alignment element and a fourth alignment element;
said first alignment element and said second alignment element are disposed generally opposite each other and on opposite sides of said shell first axis; and
said third alignment element and said fourth alignment element are disposed generally opposite each other and on opposite sides of said shell second axis.

5. The alignment assembly of claim 4 wherein:
said number of alignment elements includes a fifth alignment element and a sixth alignment element;
said third alignment element and said fifth alignment element disposed in an anti-twist configuration; and
said fourth alignment element and said sixth alignment element disposed in an anti-twist configuration.

6. The alignment assembly of claim 1 wherein when a shell is in said initial alignment position, said at least one moving alignment element body second end angled surface is disposed directly above the perimeter of the shell.

7. The alignment assembly of claim 1 wherein said upper tooling assembly includes an alignment surface structured to engage a shell and to move said shell from said intermediate alignment position to a final alignment position, said upper tooling assembly alignment surface disposed at a first elevation, and wherein:
each said moving alignment element body second end angled surface includes a lower end disposed at a second elevation, and, an upper end disposed at a third elevation; and
wherein said third elevation generally corresponds to said first elevation.

8. An alignment assembly for a press assembly, said press assembly including a transfer belt and a tooling assembly, said tooling assembly including an upper tooling assembly and a lower tooling assembly, said upper tooling assembly moving between a first position, wherein said upper tooling assembly is spaced from said lower tooling assembly, and a second position, wherein said upper tooling assembly is immediately adjacent said lower tooling assembly, said transfer belt including a number of apertures, each said aperture generally corresponding to a shell, said transfer belt positioning said shells in an initial alignment position, said alignment assembly comprising:
a number of moving alignment elements;
said moving alignment elements configured to be coupled to said upper tooling;
wherein said moving alignment elements are structured to move said shell from said initial alignment position to an intermediate alignment position;
each said moving alignment element includes an elongated body with a first end and a second end;
wherein the second end of said elongated body of each said moving alignment element includes an angled surface;
said number of alignment elements include a number of alignment cavities in said lower tooling assembly;
each said alignment cavity disposed in the path of a moving alignment element; and
each said moving alignment element configured to be disposed in an associated alignment cavity when said upper tooling assembly is in said second position.

9. A press assembly comprising:
a transfer belt;
a tooling assembly;
an alignment assembly;
said tooling assembly including an upper tooling assembly and a lower tooling assembly;
said upper tooling assembly moving between a first position, wherein said upper tooling assembly is spaced from said lower tooling assembly, and a second position, wherein said upper tooling assembly is immediately adjacent said lower tooling assembly;
said transfer belt including a number of apertures, said transfer belt apertures generally corresponding to a shell;
said transfer belt movably disposed between said upper tooling assembly and said lower tooling assembly;
said transfer belt positioning said shells in an initial alignment position when said transfer belt is not moving;
said alignment assembly including a number of moving alignment elements;
said moving alignment elements coupled to said upper tooling assembly;
wherein said moving alignment elements are structured to move said shell from said initial alignment position to an intermediate alignment position;
wherein, as said upper tooling assembly moves from said first position to said second position, said moving alignment elements contract a shell and move said shell from said initial alignment position to said intermediate alignment position;
said upper tooling assembly positioning said shells in a final alignment position as said upper tooling assembly moves from said first position to said second position;
each said moving alignment element includes an elongated body with a first end and a second end;
wherein each said moving alignment element body second end includes an angled surface;
said number of alignment elements include a number of alignment recesses disposed about the perimeter of each said belt aperture; and
each said alignment recess disposed in the path of a moving alignment element when said shell is in said initial alignment position.

10. The press assembly of claim 9 wherein each said shell includes a first a
