摘要： A product speed checking apparatus for attaching to a vibratory conveying system and a method thereof for dispensing product, including a sample pan mounted to capture flow of product between two vibratory conveyors; a first sensor and a second sensor, each placed separately at a predetermined distance from one another and each capable of independently reading product handled by the sample pan; and, a programmable logic controller operatively arranged to calculate an approximate time between the reading of product by the first sensor and the reading of product by the second sensor and computing product speed by dividing distance between two sensors with the travel time between the two sensors.

摘要： An elongate vibratory conveyor for moving products is reciprocated by driving a motor with a cyclical nonuniform motion by supplying power nonuniformly to the motor. The conveyor is reciprocated in opposite lengthwise directions, without any substantial movement of the conveyor normal to the lengthwise direction. Motor control circuitry variably drives the motor automatically in response to feedback from a sensor which senses a motion related to the conveyor motion. The feedback signal is compared to a selected one of a set of predetermined different motion patterns, and the motor is driven by supplying power nonuniformly thereto in accordance with the selected motion pattern. The conveyor system readily enables instantaneous reversibility of the product flow at the same average velocity, and instantaneous variable control for modifying the motion of the conveyor to obtain either different desired average product velocities or the same average product velocity at different conveyor inclinations or reciprocating frequencies, all irrespective of changes in conveyor loading or resistance to slip of the products conveyed. Separate motors driving either the same conveyor or separate conveyors are driven with cyclical nonuniform motions in synchronization by synchronizing their respective power supplies.
