Feeder tube for filling containers with pills
First Claim
1. A pill delivery apparatus comprising:
- a tray having an upper surface adapted to contain a plurality of pills thereon, the tray defining an inner tray aperture; and
a feeder tube extending from the inner tray aperture of the tray and adapted to deliver the pills from the tray to a container, the feeder tube comprising an inlet side proximate to the tray and an exit side opposite to the inlet side, the feeder tube defining a delivery chute extending between the inlet side and the exit side, the delivery chute defining one of the group consisting of a twisted linear shape and a helically exaggerated shape such that each of the pills rotates while proceeding through the delivery chute, the delivery chute being configured to rotate each pill at least one revolution while the pill proceeds between the inlet and exit sides, and the feeder tube being configured such that the rotation of the pills prevents jamming of the pills in the delivery chute.

Abstract
A pill delivery and packing apparatus having a feeder tube for delivering pills is provided. The feeder tube has a helical delivery chute that extends between an inlet side and an exit side of the tube. The delivery chute has a helical inner contour and a rectangular cross section that corresponds to the shape of the pills. The helical delivery chute is configured such that each of the pills rotates while proceeding through the delivery chute, whereby such rotation of the pills prevents jamming of the pills in the delivery chute. Independently extendable pins are used to alternately block and open the delivery chute, thus providing an escapement mechanism for dispensing pills. The tube also has an outer surface defining a helical outer contour that guides a rotatable tray on which pills are disposed. Associated apparatuses and methods are also provided.

16. A feeder tube adapted to deliver pills to a container, the tube comprising:
-
an inlet side; an exit side opposed to the inlet side; and a delivery chute defined by the feeder tube and extending between the inlet side and the exit side, the delivery chute defining one of the group consisting of a twisted linear shape and a helically exaggerated shape, and the delivery chute being configured to rotate each pill at least one revolution while the pill proceeds between the inlet and exit sides such that each of a plurality of pills successively disposed in the delivery chute is oriented at a successive rotational position along the delivery chute so as to prevent jamming of the pills in the delivery chute. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A pill delivery apparatus comprising:
-
a tray having an upper surface adapted to contain a plurality of pills thereon, the tray defining an inner tray aperture; a feeder tube extending from the inner tray aperture of the tray and adapted to deliver the pills from the tray to a container, the feeder tube comprising an inlet side proximate to the tray and an exit side opposite to the inlet side, the feeder tube defining a delivery chute extending between the inlet side and the exit side, the delivery chute defining one of the group consisting of a twisted linear shape and a helically exaggerated shape such that each of the pills rotates while proceeding through the delivery chute, the feeder tube being configured such that the rotation of the pills prevents jamming of the pills in the delivery chute; an upper pin and a lower pin operably engaged with the feeder tube, wherein the upper pin and the lower pin are independently extendable and retractable with respect to the delivery chute such that extension of each of the pins into the delivery chute prevents movement of the pills therethrough; and a controller configured to selectively control the extension and retraction of the upper and the lower pins and thereby release the pills from the delivery chute in a predetermined number. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
