Abstract: A work transport system including pallet handling device for moving works from a loading dock area to a production line of a plant. The pallet handling device includes a pallet delivery route and a pallet collection route. The system includes the pallet handling device, a work loading device, a conveyor, and a work unloading device.

Abstract: A conveying system has access to a first supply means (11) for supplying a plurality of types of first automobile body components (10a) having different shapes, a second supply means (13) for supplying a single type of second automobile body component (12), and conveys the automobile body components in a combined manner to a next processing station. With the conveying system, a fourth lift (16) receives first body components (10a) of a first type and second body components (12) of a single type from a first carrier (18) and delivers them via a second fork lift (23) to a transfer area near the next processing station, or receives the second components (12) via the second fork lift (23) and the first components (10c) of a second type via a third lift (40), and delivers them to the transfer area when only the second component arrives via the second fork lift (23).

Abstract: This invention relates to an overhead work suspension conveyor for conveying a piece of work, for example, a tailgate to a main body in an assembly line of a vehicle main body. An object of this invention is to efficiently and surely hold plural kinds of work pieces of different configurations in a suspended position and to permit their easy loading on a work conveyance mechanism. This invention therefore provides an overhead work suspension conveyor comprising a traverser main body, plural spindles turnably supported relative to the traverser main body, plural work support members fixed at upper ends thereof on the spindles and having work supports at lower ends thereof, said work supports being turnable responsive to turning of the corresponding spindles to support a piece of work at an outer periphery thereof, and a spindle drive mechanism arranged on the traverser main body and adapted to selectively turn the spindle depending on the kind of the work piece.

Abstract: A pair of vertical guide rails of a workpiece transporting system are comprised of upper and lower rail portions, the upper rail portions being movable into axial alignment with the lower rail portions, the upper and lower rail portions being supported from a ceiling member of a building, and thus movable in unison with each other in the event of movement of the ceiling member of the building. A joint between the upper and lower rail portions of one guide rail is arranged at a vertical height different from that of the joint between the upper and lower rail portions of the other guide rail.

Abstract: Left side panels and right side panel are produced in a left side panel production line and a right side panel production line, respectively By vertical lifters, each left side panel and each right side panel are lifted at the delivery stations and then transferred to runners at work transfer positions. The runner with the left side panel held thereon travels along a rail while the runner with the right side panel held thereon travels along a rail. Both runners are stopped at a standby position and then conveyed to a runner transfer position simultaneously. The runners with the left and right side panels held thereon, respectively, are loaded on the traverser and then conveyed to a drop lifter arranged above a main body assembly line. The left and right side panels are transferred to the drop lifter. The drop lifter then descends and feeds the left and right side panels simultaneously on opposite sides of a floor panel in the main body assembly line.

Abstract: This invention is directed to a method and a device for positioning a body transported on a conveyer as a transporting path at a longitudinal predetermined positioned or a lateral predetermined position on the path. The method positively positions the body at a plurality of positions by way of selectively shifting and holding a longitudinal positioning member or a lateral position restricting plate, which slideably contacts with a vertical projecting wall of the body, at the longitudinal predetermined position depending on the configuration of each body, prior to the arrival of the body at either predetermined position on the path.

Abstract: The conveying system is incorporated in automobile assembly line, and comprises an overhead conveyer, a shuttle conveyer, a lift for carrying a work from the overhead conveyer to the shuttle conveyer, a lift controller and a shuttle controller. The shuttle conveyer carries the work from the lift to its destination. The lift controller controls the operation of the lift, which is reciprocated vertically according to the position of a shuttle member of the shutter conveyer. The shuttle controller controls the operation of the shuttle conveyer depending upon the position of a movable work holding base of the lift. A plurality of detectors are provided so as to detect the positions of the movable work holding base of the lift and the shuttle member of the shuttle conveyer, so that the conveying system can reliably operate without the interference between the lift and the shuttle conveyer.

Abstract: A work conveying system used for conveying works such as side body panels in a car body assembling line. The system comprises hanger units, routes for conveying the hanger units which hold works to be carried, and opening-and-closing mechanisms. The hanger units are opened at a work loading or delivery area by the opening-and-closing mechanism.
