  • Patent number: 7024840
    Abstract: A vertical bagging apparatus [101] comprises a bag station [105] having multiple stations [403A, 403B, 403C, 403D] for holding a variety of wicket-supported bags. A tooling assembly [107] accepts product for a product line and dispenses the product into an opened bag from the bag station. A bag transfer assembly [109] lowers the filled bag to a bag seal assembly [111] located vertically below the tooling assembly. The apparatus allows high speeds and quick-change of bags and bagged product.

  • Patent number: 5758477
    Abstract: An interface device for packaging equipment comprises three bins arranged vertically and separated by gates located at the bottom of each bin. An infeed unit or conveyor feeds product into the receiver bin. A product counter in a logic unit counts the product fed into the receiver bin. The logic unit cycles the counted product into the buffer and discharge bins, respectively to provide an accumulator function. The logic unit cycles the discharge gate upon output of a flight sensor on the outfeed unit to deliver the counted product on the desired location of the outfeed unit. The device allows temporary differences between product flow rates between the infeed unit and the outfeed unit. No connections to the control system of the outfeed unit is required.

  • Patent number: 5092815
    Abstract: The present invention is directed to an automated poultry processing system having a novel chicken hind quarter cutting stage that does not require the individual chicken hind quarters to be removed from the moving treadmill before or after halving the chicken hind quarters. Each chicken hind quarter is placed into a moveable shackle including a rotatable shackle assembly. Each rotatable shackle assembly includes a cam plate that, when moved into contact with a stationary cam member, causes the shackle assembly to rotate 90.degree., thereby rotating the chicken hind quarter by 90.degree.. The chicken hind quarter then moves into contact with a guide member that positions the chicken hind quarter for subsequent cutting by a rotary saw. The chicken hind quarter remains in contact with the guide member until the saw has cut the chicken hind quarter into halves, thereby facilitating a precise cut of the chicken hind quarter.
