Abstract: A linear motor conveyor system with alternate drive. The system includes: at least one linear motor track section; at least one alternate drive track section having the same configuration as the linear motor track section but incorporating an alternate drive mechanism; a plurality of moving elements configured to move along the linear motor track section and alternate drive track section; and a control system for controlling the moving elements to move on the linear motor track section and the alternative drive track section. The alternate drive track section may include: a belt drive including a belt, a belt drive motor and a friction element on the moving element to engage with the belt such that movement of the belt causes the moving element to move along the track section due to friction. The alternate drive track section may alternatively include a simplified linear motor track section.

Abstract: A conveyor system configured to allow adjustment of part pitch by moving elements. The conveyor system including: a track; at least two moving elements configured to move on the track; and a pitch assembly mounted on the at least two moving elements, the pitch assembly including: at least one rail provided on at least one of the moving elements; a plurality of nests; and a mechanical linkage connected to the at least two moving elements; wherein the nests are slidably engaged with the rail to maintain linear motion and connected with the mechanical linkage such that, as the moving elements move closer together, the mechanical linkage contracts and slides the plurality of nests closer together for a reduced pitch, and, as the moving elements move apart from each other, the mechanical linkage extends and slides the plurality of nests apart for an increased pitch.
