  • Patent number: 6481602
    Abstract: The present invention provides a method and apparatus for dispensing articles into a container or basket and for controlling the dispensing mechanism to more accurately, efficiently, and intelligently dispense the desired articles with less damages to the articles. The dispenser includes a primary storage location which can take the form of a bulk storage hopper, an accumulator storage location into which the dispensed articles are transferred during the dispensing of the articles. A reversing drum and a flexible, resilient diverter are configured and arranged to reduce article breakage and/or to transfer different types of articles. The diverter apparatus is detachably mounted on an inside wall of the hopper body. The drum is also designed to provide a self-alignment between the drum and a motor shaft when the drum is mounted onto the drum motor shaft. A load/weight sensing/measuring assembly accurately and intelligently weighs the articles in the accumulator by an adaptive weighing method.

  • Patent number: 6367777
    Abstract: The present invention provides an electric version of a dispenser unit and method of monitoring a request signal for filling empty baskets, movement of the empty baskets on a loading ramp via a stop gate, and movement of the filled basket between a loading station and a staging station via a basket lift. The stop gate is driven by an electric motor, and the basket lift is driven by another electric motor. Sensors are mounted in the stop gate and the basket lift to indicate positions of the stop gate and the basket lift, respectively.
