  • Product support table having multiple product transport belts
    Patent number: 4970846
    Abstract: A product support table, having an elongated longitudinal opening is positioned over a pair of fin seal wheels which provide a seal between two edges of a sheet of film that has been wrapped around an article. The product support table supports a pair of product transport belts that are located between the product being wrapped and the product support table.

  • Double telescoping arm for robotic palletizers and the like
    Patent number: 4954042
    Abstract: A double telescoping horizontal arm, adapted for use in a robotic palletizer, including an outer member, an intermediate member and an inner member in telescoping relationship to one another. An idler wheel, mounted to the intermediate member, simultaneously engages both the outer member and the inner member so as to rotate in response to movement of the inner member relative to the intermediate member. Rotation of the idler wheel, in turn, drives the intermediate member in the same direction as the inner member thereby resulting in a double telescoping action.

  • Rotary film sealing and severing head for thermoplastics
    Patent number: 4909016
    Abstract: A rotary film sealing and severing device for use with thermoplastic film for forming packages. The device includes a rotating anvil assembly and a counter-rotating film cutting assembly having a heated sealing and cutting knife. First and second liquid cooled clamping bars on either side of the knife hold the layers of film together while the film is being sealed and cut. Cooling the clamping bars prevents the film from adhering to the clamps and causes the layers of film to quickly fuse together and allows high speed operation by preventing separation of layers of film due to slow cooling.

  • Pallet unloader
    Patent number: 4907933
    Abstract: Vehicles supporting a load are propelled between a load receiving station and a pallet unloading station. When the loaded vehicle is in a predetermined location, the pallet unloader is actuated causing the unloader ram element of the pallet unloader to contact the load and urge the load off the support vehicle and onto the load receiving station. This unloading is accomplished while the vehicle continues to move through the unloading station. The rate of unloading is coordinated with the speed of the vehicle through the unloading station.

  • Master position encoder follower system for film feeding means
    Patent number: 4868759
    Abstract: Package wrapping machine infeed conveyor and film web control utilize an infeed conveyor position signal compared to film web signal to adjust the film web letoff to the article in feed conveyor to deliver the article and the film web to a film forming location in register. A processor outputs a digital signal to a motor speed controller which will increase or decrease the feed web letoff rate. Input from the infeed conveyor may be processed by the processor to perform forward or reverse correction as necessary to synchronize the infeed conveyor with the film web letoff.

  • Computer controlled light contact feeder
    Patent number: 4852717
    Abstract: A light contact feeder uses a pair of individually controlled conveyor belts to receive randomly spaced articles and to deliver the articles in a lightly abutted arrangement. The feeder uses a trio of accumulator scanners above an accumulator belt to control belt speed and deliver lightly abutted articles to a metering belt. The metering belt delivers the articles at proper speed and phase to an article processing machine.
