ABSTRACT:
In a conveyor line, a pasta stacking apparatus is provided wherein individual spaced strips of pasta such as lasagne are automatically counted and stacked in shingles for loading into a packaging machine. The apparatus comprises an upstream conveyor belt, a downstream conveyor belt disposed slightly below the upstream conveyor belt at a junction, clutch mechanism controlling the motion of the downstream conveyor belt, an air nozzle located below the upstream conveyor belt and disposed to direct the blast of air in a downstream direction across the junction, and a photo-sensor arranged to detect items crossing the junction for operating control apparatus and for tallying the number of items delivered to the junction. In operation, lasagne strips are transported along the upstream conveyor belt to the junction where the presence of each is detected by the photo-sensor as it drops to the downstream belt. A signal responsive to the photo-sensor directs a time delayed blast of air from the nozzle, which lifts the trailng edge of the strip as it passes over the junction, flipping it over the forward edge and onto a stack of lasagne strips in the manner of shingles. During the stacking, forward movement of the downstream conveyor belt is retarded so that the lasagne strips stack in overlapping shingles upon descent to the downsteam conveyor belt. In response to the number of strips tallied by the photo-sensor, the shingled lasagne strips are separated by accelerated advancement of the downstream conveyor belt, thereby yielding a preselected count of lasagne strips in easily retrieved bundles.
