Abstract: A system for selecting one of multiple paths in a linear drive system includes track segments having a first drive member and at least one mover having a second drive member for the linear drive system. A switch track segment includes a first path, a second path, and a third path along which the mover may travel. The switch track segment also includes a first sensor positioned along the first path to detect the mover present on the first path, a second sensor positioned along the second path to detect the mover present on the second path, and a third sensor positioned along the third path to detect the mover present on the third path. The switching device is configured to engage the mover to selectively direct the mover along either the first path, the second path or the third path.

Abstract: Synchronization of multiple vehicles in an independent cart system to reduce spacing and increase throughput designates one of the movers as a leader and at least one additional mover as a follower, defining a chain of vehicles. A motion command for the chain is provided to a controller for the leader, and the controller generates a motion profile. The controller passes this motion profile to a controller for each of the follower movers. If the follower is unable to maintain the motion profile for the leader, the controller for the follower generates a message to the controller for the leader indicating a modification to the motion profile is required. The controller for the leader modifies the motion profile and forwards the modified motion profile to controllers for each follower. If all movers are following the modified profile, the controller for the leader may return to the original motion profile.

Abstract: A system for selecting one of multiple paths in a linear drive system includes track segments having a first drive member and at least one mover having a second drive member for the linear drive system. Each mover includes a drive surface oriented toward the track segment when the at least one mover is driven along the track. Each mover also includes a first channel and a second channel extending along the drive surface. A switch track segment includes a first path and a second path along which the at least one mover may travel, at least one first pin positioned along the first path, and at least one second pin positioned along the second path. The first and second pins are extendable to engage the first and second channels of the at least one mover to direct the mover along either the first path or the second path, respectively.
