Abstract
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.
Claims20
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.

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.

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.
