Abstract
A counter unit counts discrete articles that are within a predetermined size range into lots having a predetermined number of articles. The counter unit includes (1) a first conveyor that delivers a flow of articles separated at discrete intervals; and (2) at least one bin positioned to receive articles from the conveyor. The at least one bin has at least first and second outlet gates for emptying articles into separate respective first and second locations. A detector unit detects and maintains a count of articles that are received in the at least one bin and fall within said predetermined size range. The detector unit generates an out-of-size signal when an article received in the at least one bin falls outside said predetermined size range. A control unit causes the first outlet gate to open when the count of articles is equal to said predetermined number and causes the second outlet gate to open in response to receipt of an out-of-size signal.
