SIP Escapement for System

       This article describes a novel mechanical design feeds
SIPs (Single Inline Packages) from a slide pack a mechanical gripper
on a feeder mechanism.  The is passive in its design, which means
that no or air is required, nor is any computer control for its
operation.

      Referring to the figure, the slide pack mounts into the
escapement 1, and the SIPs are fed (stacked on their thin axis).

      The basic feeder consists of several parts.
     Tube Adapter 2
        The top part of the escapement 1 is machined to
        mate to a slide pack tube of SIPs.
     Pickup Guide 3
        The bottom-most SIP drops into a guide slot that
        keeps it aligned perpendicular to the feeder
        gripper.  The front of the slot is open to allow
        the SIP to be pushed out of the escapement 1 into
        the feeder gripper.
     Cam Action Lever 4
        A cam action lever 4 is spring loaded to its
        retracted position with its top behind the
        bottom-most SIP.  The bottom of the lever is
        located at a 45-degree angle underneath the
        escapement 1.  The lever is pivoted near the
        bottom of the escapement 1.  When the feeder
        gripper comes to pick a part, it fires a cylinder
        (with a cam follower) that pushes the lower
        segment of the lever away from...
