Abstract
A weight sensitive arrangement for controlling the material draw cycle of a vacuum sequencing system based on the weight of material delivered to a pellet receiver included in the system. The material is drawn by a vacuum into the receiver under the control of a dump valve. The receiver deflects downwardly when loaded and is equipped with a U-shaped deflection beam having an upper arm that deflects in proportion to the receiver deflection. A screw carried on the upper arm of the beam contacts a microswitch when the receiver is loaded to a preselected weight. The microswitch then activates the dump valve to interrupt the vacuum, thereby terminating the material draw cycle and effecting discharge of the batch of material in the pellet receiver.
