  • Patent number: 5009304
    Abstract: A multi-directional drive for roller conveyors or similar which is capable of reversible conveying of any goods deposited on it in the X and Y directions comprises essentially a plurality of rolling elements (4, 6) consecutively configured on a shaft configuration (8) which consists of a hollow quill (10) and a rotating shaft (12) mounted coaxially within it. The quill and rotating shaft can rotate independently of each other or synchronously where gearwheels (14, 16, 18) located in the rolling elements (4,6) convert the directions of rotation induced in the quill (10) or rotating shaft (12) such that the rolling elements (4,6) rotate either perpendicular to the longitudinal axis of the shaft configuration (8) or about it.
