  • Patent number: 8342508
    Abstract: A system for transporting an object between stations, for example, from a magazine to a conveyor is provided having a rotary apparatus having two arms, wherein a first arm rocks back and forth between two positions and a second arm rotates about an axis on the first arm. The second arm can be fixedly connected to a holder having one or more suction heads for grasping the object. Preferably, the holder is arranged parallel to the object and moved in a direction perpendicular to the plane of the object as the object is removed from the magazine. Additionally, the holder is preferably displaced above the conveyor and positioned to be parallel to the conveyor, after which the holder is moved toward the conveyor in a path that is perpendicular to the plane of the conveyor. Therefore, the lateral force, shearing force, and friction exerted on the object during removal from the magazine and deposition onto the conveyor can be minimized.

  • Patent number: 7810541
    Abstract: An ultrasonic welding apparatus is provided having an anvil preferably connected to a lever assembly. The lever assembly is preferably connected to a carrier via a holder, wherein the holder is pivotable with respect to the carrier, and the lever assembly is pivotable with respect to the holder. An urging device may also be provided to urge the anvil toward an ultrasonic hammer, more preferably away from the carrier.

  • Patent number: 7690706
    Abstract: An apparatus for transporting objects may include a plurality of grippers having a first spacing at a first position and second spacing at a second position. A drive mechanism may be provided is for selectively displacing the grippers from the first position to the second position to adjust the spacing between the grippers.

  • Patent number: 7591363
    Abstract: A system for dividing an object flow can provide slides which are constructed and arranged to displace one or more objects at a time from the object flow toward a different location, preferably another object flow. The slides can be pivotal away from the objects being displaced, thus releasing the objects at the desired location, the slides being reusable as the slides revolve about one or more rollers to and from displacing the objects. Preferably some of the objects are displaced from the object flow at an acute angle with respect to the direction of conveyance, which can provide displacement at a lesser force.

  • Publication number: 20080173694
    Abstract: An ultrasonic welding system is provided for creating an ultrasonically welded seam in a plurality of layers of a material, for example a foil bag having a plurality of foil layers. The system preferably includes a sonotrode and an anvil constructed and arranged to apply a welding force at an angle of less than 90° with respect to the downward force of gravity. Accordingly, a vertical welding force can be provided on the foil layers to weld the foil layers together from the bottom upward.
