  • Patent number: 5255610
    Abstract: A conveyor for a suspension conveyor system comprising a carrier bar suspended from two yokes for receiving objects to be transported. Each of the yokes is suspended from a rail by a pair of rollers and is connected to the carrier bar via at least one joint having an axis of rotation which extends horizontally to the rail and an axis of rotation which extends transverse to the rail. To make the conveyor more universally usable without any negative impact on its conveying properties, the end of the carrier bar is connected to its yoke via a pivot pin extending at right angles to the horizontal axis of rotation, the pivot pin being received in a bearing shell on the end of the bar that permits the carrier bar to be pivoted relative to the pivot pin over a predetermined angular range in a vertical plane about a horizontal axis extending perpendicular to the pivot pin.

  • Patent number: 5001987
    Abstract: A lightweight car-on-track system having a pair of spaced-apart rails and an associated rotatable drive tube with a captive carrier movable along the rails and having a drive wheel in driving engagement with the rotatable drive tube. The drive wheel is spring-loaded against the rotatable drive tube and the capture of the carrier to the rails results in a controlled drive force achieved regardless of the weight of the carrier or of a load supported thereon. The system is made up of a selected number of modular units, each having adjustably mounted frame members supporting opposite ends of a rail section and a drive tube section. Adjustable mounting of frame members to an alignment plate assures alignment between rail and drive tube sections when assembling the system. A transfer device is utilized for transferring a carrier from the end of one track section to the spaced-apart end of another track section with the transfer device being oscillatable about a pivot axis.

  • Patent number: 4746257
    Abstract: A driveway for tractor-trailers is elevated along one side having a side coupling runner mounted to roll on wheels in a track along the side of the driveway facing a single-arm rotary loader. The runner is longer than the tractor-trailer and has a lift push gate at one or both ends for lowering in front of the tractor to push the runner along its track and has recesses for vertical coupling rods or tubes on the loader's trailer-lifting turntable to engage in to move the loader with the tractor to rotate the loader into alignment under the trailer and lift for transfer. Then the tractor driver can release the fifth-wheel and lift the gate and drive away. The loader is further rotated or driven and disengaged from the runner before the runner is returned by motor drive. The loader can load the trailer removed from the tractor onto a railway car as in my earlier U.S. Pat. No.

  • Patent number: 4736687
    Abstract: A computer-controlled system for transporting workpieces, in which each workpiece is placed on a load carrier, each workpiece and load carrier being marked with an identifier. A central computer is loaded with data relative to each given workpiece, its respective load carrier, and work to be performed on such workpiece, and predetermines a path to be followed by such load carrier. The load carrier is placed on a main path, its identifier is read, and if work is to be performed on a workpiece carried thereon, a switch is thrown to divert the load carrier to an auxiliary path and then to a work station. The load carrier may be diverted to the work station by a swing-out device or by a spur path, for example. After such work, the load carrier is returned to the main path and its identifier is read again to determine whether it again is to be diverted to an auxiliary path for performing further work on a workpiece carried thereon.

  • Patent number: 4722657
    Abstract: In apparatus for transporting and storing bobbins, especially for removing them from automatic spinning machines, the bobbins are received and collected in an inclined collecting chute from a conveyor belt, are then brought into a horizontal arrangement as a result of the pivoting of the collecting chute, and are pushed in groups from the collecting chute into a transfer chute. A conveyor carrier belonging to a suspension conveyor and provided with at least one chute portion for receiving a group of bobbins is brought into a position adjacent to the transfer chute. The transfer chute is moved into a position located next to the chute portion of the conveyor carrier, and the bobbins are transferred into the chute portion of the conveyor carrier. The bobbins are subsequently moved into a desired target position by means of the conveyor carrier.

  • Patent number: 4718810
    Abstract: A high-speed, bidirectional transporter for a multiple station production line provides for the programmable pickup, transport and delivery of materials at non-sequential work stations along the production line. The transporter is self-propelled by a rack and pinion drive and moves along a track that defines a course through the multiple work stations. A turntable on the transporter carries an extensible and retractable arm whose motion, when coupled with a materialladen pallet, provides for either the pickup or delivery of a pallet to or from an individual work station. Coupling and uncoupling of the arm with a pallet is effected by the controlled rotation of the turntable, which is capable of 180 degrees of rotation to also impart to the transporter the ability to transfer pallets off of both sides to address a work station on either side of the track.
