ABSTRACT:
Elongate workpieces with enlarged heads to be distributed in groups to different destinations, such as plastic parisons to be delivered to respective mold cavities of a four-cavity blow-molding unit, are fed--partly by gravity--over a pair of sloping, counterrotating spindles to a tilted turntable, the spindles being separated by a gap letting the bodies of the workpieces hang down between them. The workpieces are successively inserted into peripheral recesses of the turntable along a raised edge thereof for rotary entrainment to respective guide channels confronting its opposite, depressed peripheral edge. Four workpieces at a time are dislodged from their recesses, after retraction of a barrier, by air jets driving them into the guide channels assigned to them. Fresh workpieces are deposited upon the upstream end of the spindle track by an elevating conveyor controlled by a monitoring device such as a photosensor which stops the conveyor upon detecting a backup of workpieces along the track.
