International Classification:

B65G 67/12
B60W 40/114
B60W 40/112
B60W 40/11

Abstract:

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.

Abstract:

An independent cart system includes an inductive link for contactless power transfer between a track and each mover as the mover travels along the track. A system for contactless data transmission between movers and a controller in the independent cart system includes a transmitter and/or receiver mounted on each mover and a complementary receiver and/or transmitter mounted on a track. The transmitter receives data to be transmitted across the inductive link and modulates a voltage present on either the primary or secondary winding to which it is coupled. The modulated voltage present on one winding induces a corresponding modulation on the voltage present on the other winding. A receiver operatively connected to the other side of the inductive link detects the modulated voltage and decodes the data from the modulated voltage received across the inductive link.

Abstract:

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.
