Abstract: A conveying system is disclosed for conveying unstable articles having a neck ring. Unstable articles, such as plastic bottles having a neck ring, or flange, are conveyed in single file along plural paths each of which is established by dual guides vertically spaced from one another a distance just sufficient to receive the neck rings of the articles therebetween, with the articles being urged in the downstream direction along each path by air acting solely on the top portion of the articles above the neck rings.

Abstract: Article diverting and storage system and method utilizing a thru-flow palletizer/depalletizer. Articles on an article conveyor are diverted from the article conveyor at a first location and moved along a first path toward a discharge end where a sweep unit of a palletizer/depalletizer urges and leads the diverted articles onto a pallet by groups for storage. When the stored articles are later needed, the articles are urged and led from the pallet by groups by the sweep unit and a retainer unit of the palletizer/depalletizer and moved along a second path separate from the first path to a second location of the article conveyor downstream from the first location where the articles are inserted onto the article conveyor. The system and method are particularly useful for storing cans diverted from a high speed can production and/or handling line, and for later supplying stored cans, when needed, to the line.

Abstract: A device is disclosed that utilizes a fluid (normally air) to effect nested alignment of articles having a circular cross-section (such as cans used to package beverages and the like). A conveying section that includes a dead plate and a fluid conveyor provides articles in a mass flow to an aligning section having guides therein spaced a sufficient distance to form guideways through which articles are fluid driven in single file toward a discharge end having an adjacently positioned staging section that also includes a fluid conveyor. The guides, other than a center guide, have first and second portions that are angled with respect to one another, and fluid injected into the sections through apertures in a base plate providing section bottoms urges the articles into a plurality of adjacent rows of aligned articles at the staging section with the articles of each adjacent row offset from one another to effect nesting of the articles.

Abstract: A device and method are disclosed for moving articles, such as cans, by groups, or tiers, from a pallet to an adjoining surface, such as a belt conveyor. A pair of sweep arms of a sweep unit move about a closed loop path to alternately engage the trailing portion of groups of articles when at a pallet sweep area to urge each group from the pallet. A pivotable retainer arm of a retainer unit, mounted on a reciprocating carriage moved by a driver following a closed loop path, engages the leading portion of the group of articles to be then moved from the pallet and thereafter leads the group from the pallet.

Abstract: Device and method are disclosed for repeatedly forming a predetermined arrangement of conveyed articles. Cylindrical articles, such as cans, are accumulated on a conveying unit at an accumulating area, the articles at the accumulating area being normally in a pattern, such as being in nested relationship. A stop unit is provided to repeatedly allow preselected numbers of articles to pass from the accumulating area on the conveying unit into a sweep area having a sweep unit including sweep arms each of which is utilized to alternately lead and push articles by group through the sweep area to a receiving area, such as a palletizer. The conveying, stop and sweep units are controlled to cause coordinated movement therebetween, the conveying and sweep units being operated at various speeds as each group of articles passes the stop unit.
