  • Patent number: 4401174
    Abstract: A weigh scale machine for automatically filling bags/containers including an infeed chute, a weigh bucket, a scale mechanism, and a discharge hopper. Initially, the flow gate located between the infeed chute and the weigh bucket is open and product is permitted to flow through the infeed chute into the weigh bucket. When the prescribed weight is attained, as determined by the setting of the scale mechanism, a weigh complete sensor is triggered and the flow gate is closed. The dump doors located at the bottom of the weigh bucket are then opened and the product is discharged through the hopper into the bag/container. Operation of the machine is controlled by a solid-state controller which includes a plurality of sensors for monitoring the actual positions of the flow gate, scale beam, and dump doors.
