<p>A vacuum single filer is provided for bringing multiple rows of containers into single file at high speeds and over a relatively short distance. This is accomplished by discharging the containers in diagonal rows of three from a slotted dead plate onto a perforated conveyor belt extending over vacuum plenum chambers having slots therein for drawing a vacuum. The slot or slots aligned with the outermost container in each diagonal row draws sufficient vacuum to hold the outer container in fixed position and a deflector is used to direct the other containers into alignment behind the outer container and to slide them laterally across the belt as the belt moves them downstream until they are finally brought into single file alignment. An infeed vacuum conveyor cooperates with the slotted dead plate to arrange the containers in diagonal rows having a precise alignment prior to being picked up by the conveyor belt.</p> |
