摘要： The invention provides in some aspects a transport system comprising a guideway having a plurality of regions in which one or more vehicles are propelled, where each such vehicle includes a magnet. Disposed along each region are a plurality of propulsion coils, each comprising one or more turns that are disposed about a common axis, such that the respective common axes of the plurality of coils in that region are (i) substantially aligned with one another, and (ii) orthogonal to a direction in which the vehicles are to be propelled in that region. The plurality of coils of at least one such region are disposed on opposing sides of the magnets of vehicles being propelled along that region so as to exert a propulsive force of substance on those magnets. In at least one other region, the plurality of coils disposed on only a single side of the magnets of vehicles being propelled in that region exert a propulsive force of substance thereon-regardless of whether the plurality of coils in that region are disposed on a single or multiple (e.g., opposing sides) of those magnets.

摘要： A system and method of determining orientation of a physical location on a cart or end effector located on the cart in an independent cart system receives a feedback signal from a sensor on the cart. A multi-axis device may generate three or more signals corresponding to X, Y, and Z axes orientations. Processing may be performed on the signals to generate a value of yaw, pitch, or roll of the cart. The feedback or processed signals are transmitted from the mover to a remote device external from the track. The real-time orientation information may be used to implement closed-loop control of an actuator mounted on or external to each cart as the cart travels along the track. Power for the devices on the mover may be provided by a battery mounted on the cart or by a wireless power transfer system.

摘要： A system and method for monitoring disturbance forces experienced by a mover in an independent cart system monitors current generated by a controller and a feedback signal corresponding to operation of the mover in response to the current generated by the controller. The controller stores a value of the current reference and of the feedback signal, sampled in tandem, and determines a disturbance force experienced by the mover as it travels along the track as a function of the stored values of the current reference and of the feedback signal. The controller may store the measured disturbance force experienced by the mover as a function of the location of the mover along the track. For each subsequent time the mover travels along the same length of track, the controller may add a compensation value to the current reference to reduce the disturbance force experienced by the mover.

摘要： A motion control system for an independent cart system provides for a minimum spacing between movers that is less than the width of a coil used to control motion of the movers. Blocks are statically or dynamically defined along the length of each track segment, where the width of a block is less than the width of a coil along the same track segment. Dividing the width of each coil into smaller block widths provides for an improved resolution of control for each mover. The blocks may also establish collision prevention between movers without requiring knowledge of the position of adjacent movers. Each block is assigned to a single mover at a time, but multiple blocks may be assigned to a single mover. A mover is permitted to only move within those blocks assigned to it and cannot have blocks assigned to it that are already assigned to another mover.

摘要： A system for wirelessly transmitting power between a track and independent movers in a motion control system includes a pick-up coil provided proximate to the magnets on the movers. The fundamental component of the voltage applied to the drive coils interacts primarily with the magnetic field generated by the permanent magnets on the movers and not with the pick-up coil. Consequently, the pick-up coil does not interfere with desired operation of the movers but rather, interacts primarily with the harmonic components and has current and voltages induced within the pick-up coil as a result of the harmonic components. The energy captured by the pick-up coil reduces the amplitude of eddy currents on the mover. After harvesting the harmonic content, the pick-up coil may be connected to another circuit on the mover and serve as a supply voltage for the other circuit.

摘要： An industrial transportation system includes one or more movers and a robot system. The robot system is configured to load one or more items on the surface of respective movers and unload the one or more items from the surface of respective movers. Each of the one or more movers includes a first surface configured to provide reversible adhesion between the mover and an item loaded on the mover. The reversible adhesion of the surface is activated at loading and deactivated at unloading.
