  • Patent number: 5474167
    Abstract: Off-loading conveyors having endless roller chains to which are mounted bow tie rollers on rods extending laterally from the chain. The bow tie rollers define concavities for receipt of product units to be conveyed and off-loaded at an appropriate station. Off-loading elements are mounted to the chains which include paddles extending to between the bow tie rollers. The off-loading elements include levers which cooperate with an actuation system to pivot the paddles through the concavities to remove product at appropriate stations.
    Type: Grant

  • Patent number: 5195628
    Abstract: An off-loading conveyor having an endless roller chain to which is mounted bow tie rollers on mounting pins extending laterally from the chain. The bow tie rollers define concavities for receipt of product units to be conveyed and off-loaded at an appropriate station. Off-loading elements are mounted about axes perpendicular to and on the chains and include downwardly inclined portions extending to between the bow tie rollers and arms which cooperate with an actuation system to pivot the downwardly inclined portions through the concavities to remove product at appropriate stations.

  • Patent number: 4961489
    Abstract: A system for the processing and handling of products including the method and apparatus therefor. A conveyor includes rocker elements fixed thereto which may be selectively tipped by means of an actuator and camming surface to off-load products conveyed in a single file arrangement. The rocker elements are positioned on a chain to form an elongate support for the conveyed products. Two conveyors positioned side by side for receiving product in series may be used to provide a full view of the surface of the product for sensing by multiple sensors.

  • Patent number: 4329831
    Abstract: Apparatus for automatically, rapidly, and simultaneously packing multiple layers of fruit, such as cantaloupes, for example, into packing boxes wherein the layers of fruit are packed in a predetermined staggered or complementary pattern. A pair of packing heads, i.e., a first packing head and a second packing head, in near side-by-side relationship, are automatically simultaneously tilted, in response to like mechanisms or actuators, to deposit the fruit which are automatically prearranged thereon in a predetermined pattern into indexed packing boxes. The second packing head which packs the top layer of fruit is set back slightly from the first packing head which packs the first or bottom layer of fruit thus allowing the second packing head to place its fruit onto the bottom layer. The container is then automatically moved forward in order that the next cycle can take place. Structure providing this unique arrangement is described.

    Inventors: Aaron J. Warkentin, Jacob Hiebert
  • Patent number: 4245936
    Abstract: A flume for transporting fruit and the like such as between a sorter and a packaging apparatus and for measuring the batches of fruit into the packaging apparatus comprises a trough for accumulating the fruit and a slowly moving paddle for directing the water flow against the fruit to transport the fruit toward an exit gate. The manner of transporting the fruit permits the use of a single production line for processing fruits of varying degrees of buoyancy, such as apples and pears, without the need for using a flotation agent in connection with the latter.

  • Patent number: 4203274
    Abstract: Articles of fruit are fed to a receiving head, positioned in a predetermined pattern for packing, transferred in that pattern to a transfer rack which advances toward and pivots into a container to be loaded, and deposits the fruit in the same pattern. Apparatus for pivoting the transfer rack as it advances toward the container includes rotational members connected by a chain. Additional articles of fruit in a different pattern are deposited as a second layer by means of adjacent duplicate apparatus.

  • Patent number: 4106628
    Abstract: Apparatus for automatically sorting fruit and the like by weight or color, or both, using conveyance system to move objects to be sorted past an electromechanical weighing station and an optical color sensing station which, in conjunction with sequential and combinational logic, compare the color and weight of the item to a predetermined criteria and sort according thereto.
