Linear Machines

Linear scale systems are designed with one or multiple lane vibratory feed pans to feed one or multiple weigh buckets. Vibratory pans continue to feed product in the weigh buckets until one of the weigh buckets senses the set point weigh. Buckets are then pneumatically or mechanically discharged.

Linear scale systems can be designed with one or multiple lanes, or heads. Each individual lane operates in the same manner, but because many weigh buckets are being used and multiple weigh buckets are being filled at once, the output of a multi-lane scale is greater than a single lane scale. Due to the operation of the linear scale, the different lanes will become staggered as to the weight of product in the individual buckets. When one weigh bucket reaches the proper weight and discharges, another bucket will be close to the proper weight, so that the interval between the discharge of the first bucket and the discharge of the second bucket is shorter than the time required to fill an entire weigh bucket.

Linear scale systems can be designed with bulk / dribble feed. Linear scale systems with bulk / dribble feed are designed to feed 80% to 85% of the weight of the product into the weigh bucket using large feed pan. Once 80% to 85% of the desired weight is sensed in the weigh bucket, a gate stops the feed from the large feed pan. A smaller feed pan continues to feed a small amount of product into the weigh bucket until the desired weight (100%) is reached. Linear scale systems with bulk / dribble operation reduce the amount of time necessary to feed the proper amount of product into the weigh bucket and increase the output of the linear scale system.
