Abstract
A marker band locator system locates a marker band, from a plurality of marker bands in a hopper, into a band receiver for further processing. A hopper is configured to loosely hold a plurality of marker bands and a band receiver, configured in an indexer, is configured under the hopper such that marker bands gravity feed down to the band receiver. A vacuum source produces a vacuum on the band receiver and if a marker band is properly located therein, the marker band forms a seal with the band receiver and the vacuum pressure exceeds a threshold vacuum pressure level. The indexer then actuates to a secondary position for further processing and removal of the marker band. If the vacuum pressure does not exceed the threshold, a burst of air jostles the marker bands in the hopper until a marker band is seated properly.
