ABSTRACT:
An automatic fastener selection apparatus for segregating a single fastener from a particular contained pile of fasteners and for depositing the segregated fastener into the intake device of a fastening machine is disclosed. The apparatus is capable of segregating headed or nonheaded fasteners within a wide range of sizes. The apparatus includes a scoop (20) that is connected to the forward end of a shaft (22). The scoop is mounted for movement into and out of a bin (24). The bin contains a pile of randomly oriented fasteners (26). When moved into the bin (24) the blade (28) of the scoop is thrust beneath at least some of the fasteners. The scoop is then tipped upwardly so that a number of fasteners remain on the upper surface of the scoop and slide inwardly to the corner (30) of the scoop. The scoop includes a vacuum port (34) and associated mechanisms for capturing a single fastener as the scoop is rotated into an inverted position within the bin, after the shaft is tilted to remove the scoop from the pile. The scoop is then retracted from the bin to a point over the intake device of an automatic fastening machine and the single captured fastener is released into the intake device.
