ABSTRACT:
A queue of randomly oriented chips is advanced down a track. Each chip in the queue is sequentially and individually elevated into a pneumatic circuit and pressed against a mirrored surface of an upper slide member to which it adheres if the chip was oriented with upwardly disposed solder lands. A jet of compressible fluid insufficient in magnitude to dislodge the chip is injected in a direction toward the queue. If the chip, alternatively, was oriented with the solder lands down, this fluid jet propels the chip about the oval-shaped pneumatic circuit so as to reorient the chip with the lands extending in the desired upward orientation, whereupon the chip is injected into a storage magazine. If the chip was adhered to the mirrored surface, after the first fluid jet, a second fluid jet is introduced to dislodge the correctly oriented chip from the mirrored surface, whereupon a third fluid jet oriented in a direction opposite to that of the first jet and in the direction of the advancing queue, propels the correctly oriented chip along a passageway to the storage magazine. This passageway joins with the oval-shaped inverting passageway which was employed to reorient or flip incorrectly disposed chips as they traversed the reorienting oval.
