Abstract
A stacker for a 3D printer apparatus contains a positioning conveyor and a support plate hinged to drop on a signal, whereupon a push plate will push a printed and powdered sheet downward and onto registration pins, to form a stacked register of such sheets.
Claims9
A stacker system for placing into registered alignment printed sheets of substrate material in a powder-based 3D-printing apparatus, comprising:
- an outfeed conveyor for delivering a processed sheet containing liquid-adhered powder away from a powdering stage;
- a stacker cage;
- a positioning conveyor inside the stacker cage controlling sheet travel after the processed sheet leaves the outfeed conveyor;
- a support plate inside the stacker cage and downstream of the positioning conveyor, for supporting the processed sheet that has passed to it from the positioning conveyor;
- the positioning conveyor and support plate each comprising a hinged connection, such that each may hinge downward to drop the processed sheet upon an electronic actuation signal.
