Aspects of a press assembly
An assembly includes a plurality of core retention elements for transferring cores to a tablet press turn table. The core retention elements may each include a core receptacle that selectively receives a core. The core retention elements may transfer the core into one of a plurality of die bores in the press turn table.
1. A core transfer and receipt assembly, comprising:
a plurality of core retention elements each having a core receptacle geometrically dimensioned to receive a core therein and an axially movable core push pin at least selectively extending into said core receptacle, said core retention elements linked together to form a loop and rotatably arranged in a press assembly;
at least one core feed aperture sized to communicate a core therethrough, said at least one core feed aperture selectively aligned with and in communication with at least one said core receptacle; and
a press turntable having a plurality of die bores and a plurality of rotating upper punches, each of said upper punches at least selectively aligned with one of said die bores, and each of said die bores selectively aligned with at least one said core receptacle;
wherein said core receptacles do not extend into said die bores;
wherein a group of said plurality of rotating upper punches is activating simultaneously a plurality of said core push pins aligned with said die bores; and
wherein at least some of said activated core push pins each have a unique axial displacement relative to other of said activated core push pins.
2. The assembly of claim 1 , further comprising a push pin at least selectively aligned with said at least one core feed aperture and sized to at least partially extend through said core feed aperture.
3. The assembly of claim 2 , wherein a plurality of said core feed apertures are provided.
4. The assembly of claim 3 , wherein said plurality of core feed apertures are rotatably arranged in said press assembly.
5. The assembly of claim 1 , wherein at least some of said core retention elements have a transfer cog extending upwardly from said core receptacle.
6. The assembly of claim 5 , wherein said upper punches selectively rotationally contact said transfer cog of said core retention elements to thereby rotate said core retention elements.
7. The assembly of claim 6 , wherein said upper punches selectively axially contact said core push pin, thereby axially moving said core push pin farther into said core receptacle.
8. The assembly of claim 1 , wherein said core retention elements are rotated in a common plane.
9. An assembly, comprising:
a plurality of core retention elements each having a core receptacle geometrically dimensioned to receive a core therein and an axially movable core push pin at least selectively extending into said core receptacle, said core retention elements rotatably arranged in a press assembly;
at least one core feed structure selectively in communication with at least one said core receptacle; and
a press turntable having a plurality of die bores and a plurality of rotating upper punches, each of said upper punches at least selectively aligned with one of said die bores, and each of said die bores selectively aligned with at least one said core receptacle;
wherein during at least some of the time in which a single of said die bores is aligned with said core receptacle of a single core retention element of said core retention elements, a single of said upper punches selectively activates said core push pin of said single core retention element, thereby axially moving said core push pin;
wherein at least some of said core retention elements have a transfer cog extending upwardly from said core receptacle; and
wherein said upper punches selectively rotationally contact said transfer cog of said core retention elements to thereby rotate said core retention elements.
10. The assembly of claim 9 , wherein said core feed structure includes a push pin selectively aligned with said core receptacle of said core retention element.
11. The assembly of claim 10 , wherein said at least one push pin is rotatably arranged in said press assembly.
12. The assembly of claim 9 , wherein said core retention elements are rotated in a common plane.
13. The assembly of claim 9 , wherein a group of said plurality of rotating upper punches is activating simultaneously a plurality of said core push pins aligned with said die bores.
14. The assembly of claim 13 , wherein at least some of said activated core push pins each have a unique axial displacement relative to other of said activated core push pins.
15. The assembly of claim 9 , wherein a plurality of said upper punches are contacting a plurality of said core push pins aligned with said die bores, and wherein at least some of said contacted core push pins have a unique axial displacement.
16. An assembly, comprising:
a chain having a plurality of core retention elements, said core retention elements each having a core receptacle geometrically dimensioned to receive a core therein, said core retention elements rotatably arranged in a press assembly;
at least one core feed aperture sized to communicate a core therethrough, said at least one core feed aperture selectively aligned with at least one said core receptacle; and
a press turntable having a plurality of die bores and a plurality of rotating upper punches, each of said upper punches at least selectively aligned with one of said die bores, and each of said die bores selectively aligned with at least one said core receptacle;
wherein at least three of said die bores may simultaneously each be aligned with a respective single said core receptacle of three of said core retention elements.
17. The assembly of claim 16 , wherein said core feed structure includes a push pin at least selectively aligned with said at least one core feed aperture.
18. The assembly of claim 17 , wherein at least some of said core retention elements have a transfer cog extending upwardly from said core receptacle and wherein said transfer cog selectively contacts at least one of said upper punches.
19. The assembly of claim 16 , wherein said core retention elements are rotated in a common plane.
20. The assembly of claim 16 , wherein three of said upper punches may simultaneously each contact a single said core push pin of said three of said core retention elements and wherein each of said contacted core push pins is uniquely axially displaced.
