Stopper elevator conveyor

Claim 1

The device for transferring small discrete objects such as pharmaceutical stoppers and caps comprising: a frame having locking castors and movably positionable at a predetermined location for delivery of said objects; an angularly displaced conveyor on said frame and having a discharge chute at a predetermined location for discharging objects thereof, said conveyor including a conveyor chain means defining a path from a transfer point to said discharge chute, said chain having bucket flight means including holes in said flights to convey said objects along said path while subjecting said objects to an ambient drying condition; 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, which end is positioned to feed said objects to said conveyor chain, said end including terminal plate means hinged to be deflected upon contact with objects carried by said conveyor, said delivery chute further including a second tray located within said first tray at the same or greater angle with respect to the incline of the first tray and positioned to receive said objects, said second tray having an open lower terminal end for feeding said objects to said first tray, said first tray being mounted to said frame on a plurality of leaf spring means, and said delivery chute further including vibrating means for oscillating said trays to impart linear 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, said hopper being mounted on a detachable mobile frame and including a hopper chute for gravity feed of said objects to said delivery chute.

Claim 2

The device for transferring small discrete objects such as pharmaceutical stoppers and caps comprising: a frame having locking castors and movably positionable at a predetermined location for delivery of said objects; an angularly displaced conveyor on said frame and having a discharge chute at a predetermined location for discharging objects thereof, said conveyor including a conveyor chain means defining a path from a transfer point to said discharge chute, said chain having bucket flight means including holes in said flights to convey said objects along said path while subjecting said objects to an ambient drying condition; 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, which end is positioned to feed said objects to said conveyor chain, said end including terminal plate means hinged to be deflected upon contact with objects carried by said conveyor, said delivery chute further including a second tray located within said first tray at the same or greater angle with respect to the incline of the first tray and positioned to receive said objects, said second tray having an open lower terminal end for feeding said objects to said first tray, said first tray being mounted to said frame on a plurality of leaf spring means, and said delivery chute further including vibrating means for oscillating said trays to impart linear 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, said hopper being mounted on a detachable mobile frame and including a hopper chute for gravity feed of said objects to said delivery chute.

Claim 4
