  • Patent number: 8465005
    Abstract: A pneumatic load balancing device having an inflatable reservoir establishing via an amplifier a pressure within a lift chamber that is sufficient to balance the weight of an object being lifted. The reservoir is inflated and deflated by inflation and deflation valves that may be operated from an operator control center proximal an end effector of the device. The valves may be actuated via pushbuttons or in a mutually exclusively fashion via a neutrally biased reciprocating actuator. The device allows loads of different weights to be lifted in a semi-automatic fashion with operator involvement to select the load balancing pressure. The device may have an air release system that closes a blocking valve in the event of release of the object and optionally in the event of a loss of air supply. The pressure within the lift chamber is thereby preserved and can be vented at different rates.

  • Patent number: 8365682
    Abstract: Substrate support methods and apparatus include vertically aligned lift pins that have bearing surfaces that engage friction plates and/or magnetic fields to maintain the vertical orientation of the lift pins during substrate lifting. In some embodiments, a magnetic field and/or weighting may alternatively or additionally be used to control the vertical orientation of the lift pins, limit the angle of the lift pins, and/or prevent the lift pins from unintentionally binding in a susceptor as the susceptor is raised and prevent the resulting uneven support of the substrate.

  • Patent number: 5069269
    Abstract: A lifting and turning unit for a melting or casting plant. The lifting and turning unit for a deposit stand, preferably a table, for ingot molds of a vacuum melting and casting plant is provided. The unit consists of a tubular, vertically arranged lifter column that is axially movable with a hydraulic piston-cylinder unit and that has its upper end carrying the ingot mold table. A guide system composed of guide columns and of a yoke is provided. The guide columns serve for guiding the lifter column and for protecting the lifter column against twisting. The drive for the rotation of the rotatable ingot mold table is connected to the lifter column away from the harsh chamber environment. The unit provides an extremely low maintenance lifting and turing device wherein the longitudinal movements and the rotary movements can be executed separately from one another and thus allow for an exact positioning of the table.

  • Patent number: 4927318
    Abstract: The output of a high speed press or bindery is formed into stacks which are then combined into four stack "cubes". The cubes are handled as units and formed into tiers which can be loaded onto pallets. A pickup head for manipulating the cubes is carried by a transport device such as a gantry or robot arm. It has a top plate which is connected to the transport device. The top plate carries horizontal guide members from which depend four side panels. The side panels may be retracted to grasp the sides of the cube or extended to release the cube. Fingers mounted along the bottom edges of the side panels are designed to extend between the bottom sheets of the cube and the surface on which it sits. They can be locked into this position, permitting the cube to be lifted and transported by the pickup head. Also disclosed is a gantry-type transport device with a telescoping extender to which the pickup head is connected.

  • Patent number: 4640657
    Abstract: A method for loading a stack of filled cartons onto a transport vehicle includes lifting the cartons at the first station on a rotator lift truck and then rotating the cartons through an acute angle to cradle the cartons for carrying purposes. The cartons are then carried in their rotative position towards a second station, and again rotated to an upright position. The cartons are compressed at the second station and thereafter loaded onto the transport vehicle by a second lift truck. The rotator lift truck utilized for effecting the lifting, rotating, carrying and compressing steps includes a mast assembly mounted forwardly thereon and a rotator attachment mounted on the mast assembly for vertical movements and for rotation about a longitudinal axis thereof.

  • Patent number: 4595331
    Abstract: Disclosed is a system for automatically loading a transport vehicle with unit loads by automatically moving the unit loads from a predetermined loading position to prescribed positions in the transport vehicle. The present invention uses a loading vehicle which receives loads from a staging device which positions the unit loads in the predetermined loading position. A unit load transfer device transfers the unit loads from the staging device to the loading vehicle. The loading vehicle uses on-board sensors in combination with placement information provided by a staging processor to perform translational and operational movements which are processed by an on-board loading vehicle processor. Unit loads can be deposited throughout the transport vehicle by maintaining a guidance path which is internally generated within the transport vehicle and can be either internally or externally generated outside the transport vehicle.
