Transporting system driven by linear motor having inductive power supply

An automated warehouse system comprising a transport unit having

• (i) a car for running on the upper surfaces of first and second rails disposed parallel to each other with each rail having a vertical webbing with inner and outer surfaces, and each rail further having horizontal upper and lower surfaces, a bottom, one side and an other side,
• (ii) a pair of wheels disposed respectively at said one and said other sides for running said car on said rails,
• (iii) a drive for moving said car on said first and second rails, and having
• (a) a linear motor body attached from said car, and facing
• (b) a horizontally disposed secondary conductor secured to said first rail,
• (iv) a power supplying system for supplying power to said drive, mounted from one side of said car, and having
• (a) two horizontally and parallel disposed induction wires secured to and along said second rail, and
• (b) at least one induction coil attached to said car and disposed between said induction wires,
• (v) two pairs of positioning rollers, one pair being attached at one side from and along the car substantially transversely from the pair of rollers attached from the other side, and
• (vi) a plurality of vertical shafts each for rotatably supporting one of said rollers for contact between each roller with an adjacent inner surface of an adjacent said rail, the rollers at said one side of the car being maintained in a fixed position relative to said car, and the rollers at the other side being urged horizontally movably within a predetermined range, against the inner surface of the adjacent rail.
