Patent number: 5839873Abstract: A storage and retrieval machine has a telescopically extendible shuttle assembly which includes a plurality of linearly movable plates and a plurality of shuttle guide roller assemblies which accommodate non-linearities in the guide surface and other variations in clearance between the shuttle guide rollers and the corresponding guide surfaces of the shuttle assembly. Each shuttle guide roller assembly includes a spring, preferably a die spring, which biases the guide roller towards the guide surface but which permits limited deflection of the roller when it encounters bows, bumps, or other variations in linearity in the guide surface. The pre-tensioned guide rollers provide wear compensation, center the shuttle plates on their tracks, and assure adequate guidance of the shuttle plates during shuttle telescoping while preventing premature wear of the shuttle guide roller bearings and/or the guide surfaces.Type: GrantFiled: March 28, 1996Date of Patent: November 24, 1998Assignee: HK Systems, Inc.Inventors: Kurt M.

Patent number: 5813816Abstract: A storage and retrieval machine has a telescopically extendible shuttle assembly and having spring tensioned shuttle idler pulleys for the slave drive members, preferably chains, of the shuttle assembly. A spring, preferably a die spring, exerts a biasing force on each idler pulley which opposes forces imposed on the idler pulley by the corresponding slave chain. Pre-tensioning the idler pulley in this manner assures adequate tension on the slave chain to prevent or at least inhibit undulations in plate movement which otherwise could occur during telescopic extension and retraction of the shuttle assembly if the slave chain were inadequately tensioned. Use of the spring loaded idler pulley also obviates the need to over-tension the slave chain and prevents or inhibits premature wear and failure of the idler pulley, pulley bearing, and/or chain.Type: GrantFiled: March 28, 1996Date of Patent: September 29, 1998Assignee: HK Systems, Inc.Inventors: Kurt M.

Patent number: 5015140Abstract: A shuttle guide for a shuttle of a storage and retrieval machine having a mast and a carriage on which the shuttle is mounted. The shuttle includes first and second plates movable relative to each other in directions transverse to the mast for carrying and depositing in or retrieving a load from a storage space. The shuttle guide comprises a first guide member having a downward facing straight guide surface extending in the transverse directions of movement of the plates and a second guide member having an upward facing inclined guide surface. The inclined guide surface is inclined upwardly relative to one of the transverse directions. A first guide roller is positioned in engagement with the straight guide surface and a second guide roller is positioned such that it is engageable with the inclined guide surface and guides one of the moveable plates in an upwardly inclined direction toward a storage space.Type: GrantFiled: September 22, 1989Date of Patent: May 14, 1991Assignee: Harnischfeger Engineers, Inc.Inventor: David A. Kling

Patent number: 5011363Abstract: A fork extension and retraction system for use with stockpickers automatically extends and retracts hydraulically extendable forks of a stockpicker when the load handler carrying the forks has moved to its extended position on the load side of the vehicle, and it also automatically retracts the forks if they have drifted from a home position before performing other fork related activities. Switches in the fork carriage assembly sense when the extendable forks are in the home position and near the home position. Other switches sense when the load handler assembly has reached its extreme positions on either side of the operator's platform. Still other switches are used to slow the traverse movement of the load handler assembly as it approaches its extreme positions, thus to cushion the shock of the load handler stopping. A control circuit senses the condition of these switches and controls the operation of both the load handle and the fork extension hydraulic system.Type: GrantFiled: December 5, 1989Date of Patent: April 30, 1991Assignee: Crown Equipment CorporationInventors: Walter Conley, III, Ned E. Dammeyer, Kim A. Klopfleisch

Patent number: 5003417Abstract: A magnetic tape cassette transport/accessor assembly is actuated by a sprocket driven, belt drive system. First and second belt drives drive the transport/accessor assembly in horizontal and vertical directions and are tensioned by spring dampener assemblies. Each spring dampener assembly dampens rough and jerky movements and effects smooth and gentle acceleration and deceleration of the transport/accessor assembly. Each spring dampener assembly also provides compensation for belt drive wear, belt stretching and differential thermal expansion and contraction of the belt.Type: GrantFiled: December 16, 1988Date of Patent: March 26, 1991Assignee: Datatape IncorporatedInventor: Frederic F.

Patent number: 4995774Abstract: A side-loading all-terrain fork lift vehicle for handling heavy loads which are long relative to their width, e.g., junked cars, and are stored in multi-level racks separated by narrow aisles and having restricted vertical clearance between levels. The vehicle body, which is about 28 feet long, has a longitudinal, low-slung, load-carrying frame section in front of an operator's cab and at its front and rear ends is mounted by hydraulic piston and cylinder units on front and rear ground wheels which can be independently driven and steered in forward or reverse through a full 180.degree. arc for straight ahead and sideways movements, for radius turning movement, and for crabwise movement. The mast is mounted on a trolley guided for reciprocal movement along a pair of transverse beams in the mid-region of the frame section which can be lowered by the hydraulic units so as to rest on the ground during on-loading and off-loading for maximum stability of the vehicle.Type: GrantFiled: April 25, 1989Date of Patent: February 26, 1991Assignee: Robert R.

Patent number: 4988262Abstract: A double reach shuttle assembly for a storage and retrieval machine. Latch mechanisms are provided on the movable elements of the shuttle to control the sequence of extension of the movable elements thereby reducing the amount of space required beneath a load in a storage rack to accommodate the shuttle elements when the double reach shuttle is used in a single reach mode. As the shuttle extends, each movable element remains stationary until the element above it reaches a predetermined point relative thereto. The invention further provides additional latch mechanisms which insure that the load carrying element of the shuttle is the last to retract.Type: GrantFiled: July 24, 1989Date of Patent: January 29, 1991Assignee: Eaton CorporationInventor: Paul K.
