<p>A weight scale machine for automatically filling bags/containers including an infeed chute, a weight bucket, a scale mechanism, and a discharge hopper. Initially, the flow gate located between the infeed chute and the weight bucket is open and product is permitted to flow through the infeed chute into the weight bucket. When the prescribed weight is attained, as determined by the setting of the scale mechanism, a weight complete sensor is triggered and the flow gate is closed. The dump doors located at the bottom of the weight 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. The controller is adapted to sequence the machine through the various functions in the weighting and filling cycle in response to feedback signals received form the sensors indicating that commanded functions have in fact been performed.</p> |
