  • Bi-directional registration of servo indexed webs
    Patent number: 5000725
    Abstract: A bag machine fabricates plastic bags by transversely cutting and sealing, at regularly spaced preselected locations, an elongate plastic web having graphic material repetitively printed thereon. In operation, the bag machine advances the web by a calculated draw length, and an optical sensor, sensitive to the passage of eyemarks printed in regularly spaced locations on the web, functions to ensure that the web is cut and sealed only at the desired locations. To avoid inaccuracies resulting from a gradual variance between the nominal draw length and the actual distance between eyemarks, a control system monitors the actual distance between eyemarks and sets the nominal draw length to the average actual spacing between eyemarks as measured over a preselectd number of successive eyemarks.

  • 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.

  • Apparatus and a method for connecting belt conveyor stringers to support stands
    Patent number: 4936443
    Abstract: An apparatus and method for connecting the opposite ends of a belt conveyor stringer to longitudinally spaced ground engaging support stands without the use of tools. The stringer is made from a length of round pipe, the ends of which have diametrically outwardly projecting locking lugs for locking the stringer ends in slotted brackets fixed to the top of the support stands. The outer wall of the bracket has a gravity actuated lug keeper plate, or a spring loaded lug keeper plate, which locks the lug in the bottom of the slots in the bracket when the stringer is rotated in one direction.

  • Vibratory conveyor
    Patent number: 4921090
    Abstract: A drive and drive controller for a vibratory conveyor, wherein the drive comprises a pair of pole pieces offset along a direction of action of the drive, and moveable in the direction of action of the drive when energized by a power signal. Preferably, one of the pole pieces is mounted to a tray portion, and the other to a kinetic balancer portion, of the conveyor. The power signal comprises a series of pulse trains of controllable frequency and duration, whereby the drive unit may be vibrated at a controllable frequency and amplitude so that the vibratory conveyor may be readily tuned to optimal performance. Optionally, the voltage level of the power signal may be reduced by an autotransformer in series with the power signal to independently control the power level.

  • 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.
