ABSTRACT:
A can end counting system which receives a stick of converted can ends, separates and counts the can ends, restacks and conveys a pre-determined number of can ends comprising an output stick to an end line packaging station. At least two counter-rotating screws, each having a separator knife positioned at the entrance end thereof, are provided with a continuous spiral groove cut into the periphery and coact with each other to separate the can ends, one by one, from an input stick and increasingly separate the can ends as they are carried toward the exit end of the device. A sensing device senses each of the can ends as they are carried toward the exit end of the device and sends a signal to a processing device which stores the total number of can ends included in a current output stick and controls a cut-off knife which separates and conveys the output stick toward an end line packaging station when a pre-determined number of can ends is attained.
