Packaging machinery for alternately inverting, collecting and grouping tapered objects in suitable quantities for packaging is disclosed. Two or more lines of containers proceed in parallel, one line remaining upright while an adjacent line is inverted in a turnover unit. Where the tapered objects are containers of products, great care and delicate handling are needed to avoid spillage or leakage. The turnover units accomplish the careful inversion of containers by indexing each container to be inverted through a radial path. Along the path the containers are first supported by carrying plates contacting the bottoms of the containers, then by the member forming the radial path, and finally by succeeding support plates contacting the tops of the containers. The adjacent line or lines of upright containers proceed in parallel with those passing through the turnover unit and a shuttling carriage groups the output of the lines for suitable nesting and arrangement.
Packaging machinery for arranging tapered containers having lids in nested groups comprising means for moving said containers in upright positions along generally parallel lines to a delivery point, turnover unit disposed in at least one of said lines but not in others of said line for inverting containers moving in said one of said lines, said turnover unit including members depending downwardy from said one of said lines and defining a substantially enclosed radial path, a plurality of support plates disposed at right angles to said radial path, means for sequentially indexing said plates to predetermined positions along said path, means for moving individual ones of said tapered containers in upright positions from said one of said lines onto one of said support plates, whereby said individual tapered container is lowered along said radial path to rest upon said members adjacent the low point thereof, a following support plate contacting the lid of said container and raising it further along said radial path in inverted position to a point adjacent said delivery point.
