    Abstract: A transportation system uses a carrier conduit in the form of a long tube or channel in order to drive a vehicle by air pressure. A carrier having end plates obstructs the travel of air through the carrier conduit. Pressure differentials formed within the carrier conduit serve to propel the carrier through the carrier conduit. By rollably supporting the carrier within the carrier conduit, friction is reduced between the carrier conduit and the carrier. The carrier may be magnetically coupled to a vehicle having vanes and a set of track- or rail-engaging wheel assemblies on vanes. The vanes may pivot upon the vehicle and serve to allow the vehicle to rollably or slidably couple to the carrier conduit track. The motion of the carrier serves to propel the vehicle along the carrier conduit track as the vehicle is magnetically coupled to the carrier.

  • Patent number: 5575216
    Abstract: The linear motion rolling guide unit has a top seal secured to the casing which comprises a pair of lip seals that are in sliding contact with side areas of the upper surface of the track rail. The lip seals each have a pair of lip portions that incline from a base portion outwardly toward the sides of the casing. Because the lip portions are spaced a predetermined distance from each other, their sealing actions are not affected by each other, effectively preventing further ingress into the raceway grooves of foreign matters that have entered into the slider. When the pressure in the raceway grooves is increased by the supplied grease, the lip portion on the outer side is pressed with an increased force against the upper surface of the track rail, effectively preventing leakage of the grease.

  • Patent number: 5555814
    Abstract: An improved monorail-type track section for use in a material handling and sortation system in which one or more train-type trolleys or cars runs along the track between various sortation and handling stations. The track section comprises a substantially hollow, vertical support member terminating at an upper end in an upper transverse leg defining upper wheel bearing surfaces on each side of the support, and terminating at a base end in a transversely extending base leg defining lower wheel bearing surfaces on each side of the vertical support. The upper and lower wheel bearing surfaces are angled to trap upper and lower wheel assemblies on a trolley in a torsionally stable mounting arrangement. The spacing of the upper wheel bearing surfaces is less than that of the lower wheel bearing surfaces, such that removal of the upper wheel assemblies allows the entire trolley to be lifted vertically off the track section with clearance for the lower wheel assemblies.

  • Patent number: 5492066
    Abstract: A linear motor driven transport system of an improved design is presented. The conventional roller configuration for holding the transport vehicle on the rail track has been replaced with a spring-loaded design so as to maintain the contact between the roller and the rail surface regardless of the curvatures in the routing track. Weighing device of an improved direct-loading design is adopted to improve the ruggedness of the device. Devices for controlling the positioning of the transport vehicle, including the carrier, have been simplified and the number of component pieces reduced to lower the cost of manufacturing the transport system. The container and track configurations have also been modified to enable efficient track set-up and loading/unloading of goods in complex track routing in a limited space.
