Multi-Conveyor recently built a stainless steel constructed 2:1 vertical merge conveyor designed to transport individual bags of frozen food. The bags are said to be discharged randomly from both a primary and secondary bagger onto two 90-degree curve incline conveyors, built at different elevations, that ultimately merge onto a single conveyor line.
Three servo-driven metering belt conveyors were placed before the merge. The bags detected on the top conveyor are “injected” into the gaps on the bottom conveyor with the assistance of vacuum metered belting prior to the merge. Individual baggers deposit on both lines at predetermined speeds providing minimum gaps between the product to complete the vertical merge.
The bag merge gap incorporates among other things standalone electrical controls, VFD’s, Rockwell automation Panelview Plus, and two remote e-stops. Bags may occasionally contact each other but will exit the combined conveyor with no gap. The system transports over 100 bags per minute at 220 feet per minute and 100% accumulation.
