  • Patent number: 8302536
    Abstract: A rail system for a powered pallet conveyor, which comprises alternative pathways having an electric cable provided on at least one of n parallel rails defining a travel pathway, wherein n?2, whereby the rail system includes a switch for switching between m alternative travel pathways, wherein m?2, and allowing the vehicle to continuously move across the switch after switching. The switch comprises a first actuator for selectively positioning (m*n) rigid rail portions bridging the distance between rail ends at (i) n joining points where the n parallel rails of each of the m alternative travel pathways subject to switching converge, and (ii) (m*n) continuation points where each alternative pathway subject to switching diverges downstream from the joining points A second actuator selectively positions [m(n?1)] rigid rail portions bridging the distance between rail ends, where each alternative pathway is discontinued downstream from the corresponding continuation points.

  • Publication number: 20120272856
    Abstract: According to one embodiment, a guideway switching mechanism includes an elongated section of flexible guideway coupled to a switch plate. The flexible guideway has a first end that may be coupled to a first elongated guideway and a second end that may be selectively coupled to one of a multiple quantity of alternative guideways. The switch plate provides selective coupling of the flexible guideway to multiple alternative guideways by movement through an arcuate path such that the automated transport vehicle may selectively move from the first elongated guideway to either of the alternative guideways.

  • Patent number: 8166884
    Abstract: A switch assembly for magnetic levitation railways includes a girder extending in a travel direction (x) and flexible transversely to it is provided with travel way or equipment parts. A rail and a rack are located transversely to the travel direction. A load-bearing frame, receiving the girder, has a rotatably supported carrying wheel braced on the rail and a drive mechanism with a gear wheel meshing with the rack and with a motor intended for driving it. Switch adjustment is effected by displacement of the load-bearing frame along the rail by means of the drive mechanism and a thus-effected flexing of the girder. The girder, the load-bearing frame and the drive mechanism form a solidly joined-together structural unit which as a whole is located displaceably in the travel direction (x) relative to the rail and the rack.

  • Publication number: 20120090497
    Abstract: A system for moving vehicles along two tracks that are in each case formed by two guides, in particular rails. The vehicles are moved by endless conveying cables to which the vehicles may be coupled. The two tracks have a switch in the regions of the end stations and where appropriate along the course, by way of which they are brought together. The switch has four guides which are located next to one another. The middle two guides, which are rigidly connected to one another, are pivotal about a first axis and the outer two guides, which are connected to one another in an articulated manner, are pivotal about two further axes that are spaced from one another. The switch that is formed by the four guides can thus be pivoted out of a first position into a second position.

  • Patent number: 7997208
    Abstract: A lateral transfer apparatus for an overhead conveyor comprises generally horizontally extending, side-by-side load tracks for receiving load-bearing trolleys for movement along a first track, and for movement along a second track. A transfer shuttle unit has a normal position aligned with the first track and provides a continuation thereof, and a transfer position aligned with the second track to provide a continuation of the second track. An actuator connected with the shuttle unit shifts it between the normal and transfer positions thereof at an acute angle to the tracks, thereby transferring trolleys to a position aligned with the receiving track for movement therealong.

  • Patent number: 7966942
    Abstract: The invention relates to a bending mount (24) for a switch arrangement for magnetically levitated railways. The bending mount comprises at least a box-shaped support element (25) that extends in the longitudinal direction (x) and on which are fixed successively arranged supporting metal sheets (27) that extend on both sides of the support element and serve to assemble the pieces of equipment (10, 12). According to the invention, the supporting metal sheets (27) are configured as single-piece components which extend over the width of the bending mount and are interlinked in the longitudinal direction to form a chain. Said chain essentially does not influence the flexural rigidity of the support element (25) in the desired direction (y) of a switching arrangement but exhibits a high rigidity against torsion about the longitudinal axis (x) and against vibrations in the vertical direction (z).
