Abstract
A package fill height detector comprises a probe for abutting a batch of product in a package, means for inserting the probe into an opening in the top of the package so that the probe rests on the product, and a sensor for sensing the height of the probe when it rests on the product in the package to determine the fill height of the package. The means for inserting the probe into the package comprises an arm which supports the probe, a motor for rotating the arm and a cam for guiding the arm downwardly into the package until the probe rests on the product within the package and then upwardly out of the package. An associated weighing and packaging system includes a control coupled to the sensor for decreasing the delivered weight of subsequent batches of product when the fill height is below a target level and vice versa.
