Component feed mechanism

Claim 2

In a machine for sequencing and inserting components provided with bodies and generally parallel, oppositely spaced leads projecting therefrom, said machine having an inserting head, a plurality of raceways arranged in a series for slidably supplying said components in selected succession from the respective raceways, each of the raceways including a land having lead engageable sides parallel to internal adjacent walls of the raceways and a component body engageable side, and a picker assembly movable between successively selected raceways and the head to deliver components one at a time from a delivery end of a selected raceway to the head, an escapement mechanism associated with at least the selected raceway and comprising flat leaf spring means having portions closeable yieldably toward the lead engageable side of said land to cooperatively orient and hold a component in temporary fixed position by forces applied to the component from opposite directions and transversely of the raceway, and means mounted on the picker assembly for actuating the closeable leaf spring means.

Claim 3

The combination with a vertically disposed raceway for feeding dual in-line electronic components arranged in tandem, each of the components including a body having an inner side and a plurality of leads projecting from opposite sides of the body, the raceway having a land formed with vertical parallel sides for slidably engaging the leads and inner sides of the component bodies and an adjustable wall slidably engageable with outer sides of the bodies to constrain them in their path toward a delivery end, of escapement mechanism comprising stop means movable into and out of said path to retain and release the endmost component in the raceway, movable means closeable widthwise of the raceway and said wall and arranged above the stop means for yieldably engaging opposite leads of the next-to-endmost component in the raceway path to urge them simultaneously into clamping and parallel relation with opposite sides, respectively, of the land thus to true the next-to-endmost component into a subsequently releasable condition upon opening of said means without causing tilting of the next-to-endmost component into interference relation with said adjustable wall or adjacent components in the raceway, and means for alternately actuating the stop means and said movable means.

Claim 4

The combination with a vertically disposed raceway for feeding dual in-line electronic components arranged in tandem, each of the components including a body having an inner side and a plurality of leads projecting from opposite sides of the body, the raceway having a land formed with vertical parallel sides for slidably engaging the leads and inner sides of the component bodies and an adjustable wall slidably engageable with outer sides of the bodies to constrain them in their path toward a delivery end, of escapement mechanism comprising stop means movable into and out of said path to retain and release the endmost component in the raceway, movable means closeable widthwise of the raceway and said wall and arranged above the stop means for yieldably engaging opposite leads of the next-to-endmost component in the raceway path to urge them simultaneously into clamping and parallel relation with opposite sides, respectively, of the land thus to true the next-to-endmost component into a subsequently releasable condition upon opening of said means without causing tilting of the next-to-endmost component into interference relation with said adjustable wall or adjacent components in the raceway, and means for alternately actuating the stop means and said movable means.
