ABSTRACT:
An improved feeder unit and method for use in a weighing system is disclosed wherein a bulk and a dribble feeder are positioned in close proximity to each other with both feeders being vibratory feeders. Positioned over the vibratory dribble feeder is a movable wiper blade which is utilized for wiping a portion of the bulk objects from the dribble feeder into the bulk feeder with the movable wiper blade allowing a controlled portion of the bulk objects to remain on the dribble feeder. The controlled movement of the wiper is utilized to allow a predetermined amount of the bulk objects being fed by the dribble feeder to pass under the wiper without jamming between the wiper and the dribble feeder thereby providing a much improved feeder unit. Also disclosed is a method for controlling the flow of bulk objects on a dribble feeder and for reducing jamming of the bulk objects on the dribble feeder which comprises the steps of providing and positioning a wiper over the dribble feeder to wipe a pre-determined amount of bulk objects away from the dribble feeder and allowing the wiper to move a controlled predetermined amount in order to prevent jamming of the bulk objects remaining on the dribble feeder from beneath the wiper thereby resulting in a much improved control of the flow of bulk objects.
