ABSTRACT:
A pick-and-place glue applicator is disclosed having a drive shaft mounted on a frame member for rotation about a primary axis of rotation. A support shaft is mounted on the frame member for rotation about a secondary axis of rotation which is parallel to and spaced from the primary axis. Planetary gearing causes the support shaft to orbit the primary axis and rotate about the secondary axis in a direction opposite the direction of the orbit. A suction cup is secured to the support shaft and extends radially therefrom to a suction end. The suction cup moves in a generally hypotrochoidal path. The hypotrochoidal path includes three positions where the suction cup is facing outwardly away from the primary axis. The three outwardly projecting positions are connected by connecting paths where the suction cups face inwardly toward the axis. A glue applicator is disposed within the area bounded by the hypotrochoidal path and presents a glue applying surface opposing a linear portion of the continuing path between an article pick up location and an article discharge location. As an article carried by the suction cup moves across the connecting path, it receives an elongated bead of glue from the glue applicator.
