Cup conveyor
First Claim
1. A device for conveying cup-shaped objects adapted for use in a space defined between the bed of a mechanical press and a lower die shoe mounted on the press which forms said cup shaped objects, said device comprising means for establishing a pressurized source of air and means for feeding the pressurized air to a plenum wherein said plenum is characterized as having an upper deck surface having a cup-shaped object receiving zone where said objects are successively deposited, one or more holes located within said upper deck surface at said receiving zone for the discharge of air from said plenum and an upstream exhaust duct positioned to direct a flow of air longitudinally above said upper deck surface for moving said cup-shaped objects longitudinally along said upper deck surface, said upstream exhaust duct having an air discharge port being concave and circular in shape wherein its circular curvature is radially equidistant from a center point defined by a geometric center established at the point at which said cup-shaped objects are received upon said receiving zone.

Abstract
A device for conveying cup-shaped objects, such as the bodies of two piece cans located between the bed of a mechanical press and a lower die shoe. A plenum is provided with a perforated upper deck surface for directionally expelling air which, together with an exhaust duct located upstream of the perforated upper deck surface, act to move the cup-shaped objects to a down-stream location for further processing.
