Stopper elevator conveyor
First Claim
1. A device for transferring small discrete objects such as pharmaceutical stoppers and caps, comprising:
- a frame movably positionable at a predetermined location for delivery of said objects;
an angularly displaced conveyor on said frame and having a discharge chute at said predetermined location for discharging objects thereto, said conveyor including a conveyor chain means defining a path from a transfer point to said discharge chute, said chain having bucket flight means for conveying said objects along said path;
a delivery chute on said frame for transferring said objects to said transfer point, said delivery chute including a first tray inclined with respect to the horizontal and having an open lower terminal end adjacent said transfer point positioned to feed said objects to said conveyor chain, said delivery chute further including a second tray located within said first tray at the same or greater angle with the horizontal and positioned to receive said objects, said second tray having an open lower terminal end for feeding said objects to said first tray, said delivery chute further including vibrating means for oscillating said trays to impart movement of said objects toward the lower terminal ends of said trays; and
hopper means removably mounted on said frame for holding a quantity of said objects including a hopper chute for gravity feed of said objects to said delivery chute.

Abstract
A device for transferring small discrete objects such as pharmaceutical stoppers andn caps including a frame movably positionable at a predetermined location for delivery of the objects and an angularly displaced conveyor on the frame having a discharge chute at the predetermined location for discharge in objects thereto. The conveyor includes a conveyor chain apparatus defining a path from a transfer point to the discharge chute. The chain has bucket flight apparatus for conveying the objects along the path. A delivery chute is also on the frame for transferring the objects to the transfer point. The delivery chute includes a first tray inclined with the horizontal and having an open lower terminal end adjacent the transfer point positioned to feed the objects to the conveyor chain. The delivery chute further includes a second tray located within the first tray at the same or greater angle with the horizontal and positioned to receive the objects. The second tray has an open lower terminal end for feeding the objects to the first tray. The delivery chute further includes vibrating apparatus for oscillating both of the trays to impart movement of the objects toward the lower terminal ends of the tray. Finally, a hopper apparatus is provided, which is removably mounted on said frame for holding a quantity of the objects. The hopper apparatus includes a hopper chute for gravity feed of the objects to the delivery chute.
