A differential impulse conveyor system including detectable markers disposed in a series on a moving component of the conveyor system. A stationary sensor disposed in close proximity to the markers generates a signal when the moving component is in a first range of motion to dispose the markers proximal to the sensor, and the sensor either fails to generate a signal when the moving component is not within the first range of motion. The sensor signal causes a current conditioning device to condition current from a current source to operate a motor to power the conveyor tray at a first rate of acceleration in a first mode, and the lack of the signal causes the current conditioning device to operate the motor to power the conveyor tray at a second rate of acceleration in a second mode. Markers may be positionable to optimize the timing of the current modes.

A conveyor for separating, singulating or conveying bulk material comprises a conveying plate, a substructure and a pulse generator for generating an oscillation. The substructure stands on a base surface. The conveying plate is arranged on the substructure at a distance from the base surface. The pulse generator is fixed on the substructure and is/can be brought into an operative connection with the conveying plate. The oscillation generated by the pulse generator can be transmitted to the conveying plate and a force is exerted on the substructure by the oscillation. The conveyor comprises an equalising pulse generator which is fixed on the substructure and creates a counter-oscillation. A counter-force which is in an opposite direction to the force is exerted on the substructure by the counter-oscillation. A resultant force which results from the force and the counter-force and which acts on the substructure is reduced by the counter-force.

A differential impulse conveyor system including detectable markers disposed in a series on a moving component of the conveyor system. A stationary sensor disposed in close proximity to the markers generates a signal when the moving component is in a first range of motion to dispose the markers proximal to the sensor, and the sensor either fails to generate a signal when the moving component is not within the first range of motion. The sensor signal causes a current conditioning device to condition current from a current source to operate a motor to power the conveyor tray at a first rate of acceleration in a first mode, and the lack of the signal causes the current conditioning device to operate the motor to power the conveyor tray at a second rate of acceleration in a second mode. Markers may be positionable to optimize the timing of the current modes.

A vibratory apparatus includes a deck and an exciter assembly coupled to the deck. The apparatus also includes a motion sensor, a weight sensor, and a control system coupled to the exciter assembly, the motion sensor, and the weight sensor. The control system is configured to pause the rate of travel of the material across the deck for a weighing interval, to receive the signal from the weight sensor representative of a material weight on the deck during the weighing interval, to resume the rate of travel for a transporting interval, to receive a signal from the motion sensor representative of a material flow rate during the transporting interval, to determine a material mass flow rate based on the signals from the weight sensor and the motion sensor and the weighing and transporting intervals, and to vary the operation of the exciter assembly according to the material mass flow rate.

The vibration feeder has a drive unit comprising a vibration drive, a carrier arrangement comprising a feeding element for the material to be conveyed and a control for the vibration drive, wherein an acceleration sensor is arranged on the drive unit, which when the vibration feeder is operating, detects the actual acceleration of the drive unit, and wherein the control is configured to use the actual acceleration signal of the acceleration sensor for generating a regulating variable for the vibration drive such that the carrier arrangement vibrates essentially within its resonance frequency (f.sub.res). This makes it possible, during operation, to detect the acceleration of a drive unit of the vibration feeder and to generate therefrom a regulating variable for a vibration drive such that a carrier arrangement of the vibration feeder vibrates closer to its resonance frequency (f.sub.res) or is brought back again to the same. In addition the inventive control may be used to also regulate the amplitude of the carrier arrangement and the associated mass flow m to a required value.
