A vibratory conveyor includes a feed tray, an electromagnetic linear actuator and a movable drive train interconnecting the feed tray and the electromagnetic linear actuator such that the electromagnetic linear actuator will move the feed tray during energization of the electromagnetic linear actuator. A sensor assembly is positioned to detect movement of the electromagnetic linear actuator. A controller connected to receive an output of the sensor assembly and connected to control energization of electromagnetic linear actuator, wherein the controller is configured to adjust energization of the electromagnetic linear actuator based upon the output of the sensor assembly. A vibratory conveyor in which the movable drive train includes at least one parallel spring element therealong is also disclosed.

An electromagnetic drive mechanism for use in powering vibratory equipment is provided. As one example, a drive mechanism may include a plurality of deflectable elastomeric springs in a configuration that allows the auxiliary springs to achieve a vertical, non-linear spring rate increase.

As one example, a drive mechanism may include a plurality of deflectable elastomeric springs in a configuration that allows the auxiliary springs to achieve a vertical, non-linear spring rate increase that may be beneficial in dual mass electromagnetic feeder and conveyor systems.

A excited frame conveyor includes a reciprocally moveable elongated conveyor bed, having a product conveying surface, and a stationary base which supports the elongated conveyor bed spacedly adjacent the stationary base on a plurality of elongated resilient spring legs, and the stationary base has a magnetic drive which is oriented in spaced relation relative to the conveyor bed and which, when selectively energized and selectively deenergized, imparts reciprocal motion to the elongated conveyor bed to move the product along the product conveying surface of the elongated conveyor bed.
