    摘要: A device for continuous, gravimetric metering and pneumatic conveying of pourable material provides that a material stream is conveyed over a measuring path while charging a load measuring device and the product of moment load and conveying speed is formed. The conveyor is in the form of a rotor having an essentially vertical axis and conveyor pockets in the form of chambers or cells which are moved with the rotor in a circular orbit over the measuring path. A housing surrounds the rotor in a pressure tight manner and includes a charging aperture and an emptying aperture which are rotationally displaced from one another. A load measuring device is connected to the housing and a tachometer is provided for measuring the angular velocity of the rotor. A pneumatic conveying system is provided which has feed lines respectively communicating with an air feed aperture in the housing and the emptying aperture.

    摘要: Feeder apparatus in which bulk material, in fibrous or stringy form, is delivered onto an endless belt by means of a rotating rake. The weight of the material on the belt is sensed by a transducer which effects the operation of a control system for automatically adjusting the belt speed to maintain a constant discharge of the material from an end of the belt. Excess material deposited on the belt is returned to the hopper by the rotating rake.

    摘要: A vibratory feeder system is disclosed which employs control circuitry for controlling one or a plurality of vibratory feeders such that product is discharged at a constant weight per unit time. This is preferably achieved by deriving a weight analog representative of product weight and then using this information for controlling product velocity as by modulating the tray velocity or varying the flow of product from a supply source to the tray.

    摘要: An arrangement for determining the weight of an object relative to a predetermined reference weight. A compliant system is vibrated along a predetermined axis substantially at the mechanical resonance frequency, said system having means for supporting the object. The system oscillation amplitude is proportional to the inertia of the system and is independent of gravity. The oscillation amplitude of the system is converted into an electrical signal which is compared with a reference signal representative of the reference weight and an error signal is utilized to provide a measurement and/or control function in correspondence with the difference between the weight of the object and the reference weight.

    摘要: The throughput of a conveyor belt is controlled by a motor whose speed is established by the instantaneous state of an up/down counter. The counter is incremented upwardly by setpoint pulses representative of the desired mass flow rate, and downwardly by feedback pulses from a rate multiplier representative of the actual mass flow rate. When the actual mass flow rate is equal to the setpoint flow rate, the average number of setpoint pulses will equal the average number of feedback pulses with the result that the state of the counter will be stable with time. Speed control means for the motor maintains the belt speed at a level dependent upon the state of the counter. A variation between the actual and desired mass flow rates is manifested by a change in the average number of feedback pulses which results in a change in the state of the counter. The resultant change in the motor speed and hence the belt speed restores the average number of feedback pulses to equality with the setpoint pulses thus restoring stability to the counter and restoring the actual mass flow rate to the setpoint rate.
