Abstract
A vacuum operated accumulating conveyor including a table with a slick top surface having an elongated gap. A perforated belt moves along said gap above the open ends of a plurality of vacuum chambers arranged end-to-end at spaced intervals beneath the upper run of the belt. A vacuum generator is coupled to each vacuum chamber. A proximity sensor is arranged adjacent to each vacuum chamber. A controller controls the operation of the vacuum accumulating conveyor to collect a group of bundles upon the conveying table by selective operation of the vacuum generators which create a vacuum condition in the associated vacuum chambers to draw a bundle toward the belt to move each bundle a predetermined distance for initially collecting a group of bundles of a desired number and thereafter delivering the group of bundles collected to suitable take-off apparatus. Bundles may also be advanced without being collected in groups. The selective operation of the vacuum generators conserves energy.
