Abstract
A method of aligning sticks in which the sticks are oscillated in a receiving zone where they are aligned and conveyed to a collecting zone where they are stacked in parallel side-by-side relationship. The collecting zone is vibrated to dispense the sticks laterally, still in parallel alignment. An aligning tray has two sets of parallel, elongated channels and is reciprocated vertically and in a direction parallel with the channels. Randomly oriented sticks are fed to the first set, aligned in the channels, fed to the second set, which has half as many channels, and then fed through sloping chutes to a set of hoppers. The hopppers and chutes are vibrated vertically and receive the sticks in parallel stacks. The vibrating motion causes the sticks to leave the hoppers laterally and roll down ramps to a non-vibrating conveyor belt which translates the sticks in a direction perpendicular to the long dimension of the sticks to a receiving location.
