  • Patent number: 4738578
    Abstract: A cargo reclaiming apparatus that may be fitted to a ship for emptying bulk solid material from the holds or to a warehouse for emptying such material from storage bins. The apparatus has a gantry movable across the top of the storage containers, a rotatable structure mounted to the gantry, and a boom supported by and extending from the rotatable structure at a selectable angle. The boom has a digging wheel at its outer end for feeding material to the inner surface of a belt encircling the boom. The material passes through the rotatable structure and gantry and is fed to a collection location. The belt on the boom may carry material from the container even when the outer end of the boom is positioned above the end of the boom connected to the rotatable structure.

  • Patent number: 4736831
    Abstract: The invention pertains to an apparatus that orients unfilled cans having an open end and a closed end such that all of the open ends face the same direction. Unoriented or scrambled cans are first loaded onto a vacuum belt and then conveyed into a sorter mechanism. The ends of the cans are coupled to the vacuum belt by a partial vacuum. The closed ends are distinguished from the open ends by proximity switches which control a solenoid regulated air blast capable of knocking cans having their open ends facing one direction off of the vacuum belt and into a gravity track. The cans are turned to a desired orientation as they descend through the gravity track. Cans on the vacuum belt having their open ends facing in another direction are not subjected to an air blast and are removed from the vacuum belt by another gravity track which turns descending cans into the same desired orientation. The newly oriented cans blend together upon exiting from either gravity track.

  • Patent number: 4733769
    Abstract: A device is provided for counting moving objects, such as eggs lying on a moving conveyor belt. This device comprises a lever which can be moved by the moving objects, a signalling element for generating a detectable signal as a response to a movement of the lever, and a coupling and resetting mechanism for transmitting the movement of the lever to the signalling element and for automatically resetting both the lever and the signalling element during a decrease in the size of the portion of a moving object which is in contact with the lever, after a preceding increase thereof and the associated generation of a signal. The coupling and resetting mechanism comprises an essentially cylindrical drum which is rotatable about a shaft and which is provided with a projecting part extending essentially in a radial direction for operating the signalling element. A cord is looped round the drum.

  • Patent number: 4732268
    Abstract: An arrangement on a conveyor of the type which comprises a flexible chain whereupon objects, e.g. parallelepipedic packing containers, are conveyed. The conveyor comprises guide rails (4) located on either side of the chain (1) which steer the packing container. In curves the guide rails are substituted on the one side by a curve disc (5) having a sloping steering surface (8) which acts upon the packing container outwards against the guide rails located on the opposite side of the conveyor. As a result packing containers of different sizes can be conveyed on the conveyor without the conveyor needing adjustment.

  • Patent number: 4730719
    Abstract: Rollers for use with singulators for orienting articles, typically fruit, prior to optical sensing, for example, of the fruit's surfaces, wherein fruit having diverse diameters, irregular shapes and bumpy surfaces are properly oriented by contacting a pair of symmetrically disposed truncated conical surfaces sloping uniformly inwardly to a point short of center to form a sheave portion, as well as a deep pocket within each roller and between adjacent rollers, and wherein spacing between rollers remains constant notwithstanding the diverse diameters of the fruit. A drive belt is engageable within the sheave portion of the roller for controlling speed and direction of rotation of the rollers.

  • Patent number: 4730717
    Abstract: A curved escalator comprising a plurality of segment steps having step axles connected to an inner and an outer endless loop of step chains so that the steps circulate along the endless loops, and inner and outer sprocket wheels having different diameters for turning around the step axles along a conical surface in turn-around portions of the loop in engagement with the inner and outer endless chain loops, the bottom surfaces of the teeth being engageable with the step axles of the inner and outer sprocket wheels having sloped surfaces that are parallel to the axis of the step axles in the turn-around portion, and the teeth having the same pitch circle. Since the bottom surfaces of the teeth engaging the step axles have sloped surfaces that are parallel to the axis of the step axles in the turn-around portion, and since the pitch circles of the teeth are the same, the driving force is transmitted to the step axles and the step chain, and the steps are smoothly turned around to provide a better ride.

  • Patent number: 4730721
    Abstract: A harvester of the riding type for tobacco or other leaf crop plants grown in parallel rows. The harvester comprises a vehicle of suitable height and width to span several plant rows. Primers' stations are suspended from the vehicle at a height from the ground suitable for the harvesting of the crop plants. One station is provided for each row. The vehicle has a platform positioned above plant height for an operator who manually transfers harvested leaves to a container located on the platform from conveyors provided at each of the stations for raising the leaves to the platform. The conveyors are positioned to partially surround the container at evenly spaced locations in order to minimize the total distance moved by the operator between the conveyors and the container. The vehicle has a lifting device used to interchange the container, when full, with an empty container and to unload the containers at the end of a row of plants.

  • Patent number: 4729470
    Abstract: A conveyor system (28-30) includes a track (110) and a conveyor chain (70) for movement along the track. The conveyor chain comprises a plurality of identical links (72) each including a first connection member (74), spaced, parallel, longitudinally extending plates (76) and a second connection member (78). The plates are connected to the connection members for pivotal movement about vertical axes, and the connection member of adjacent links are connected to each other for pivotal movement about horizontal axes thereby accommodating horizontal and vertical flexure of the conveyor chain. The conveyor chain (70) is actuated by a drive mechanism (180) including a drive chain (198) and chain engaging members (206) carried thereby which engage the conveyor chain along an arc having a substantial radius, thereby propelling the conveyor chain through the track (110) without subjecting the conveyor chain to periods of high acceleration.

  • Patent number: 4724947
    Abstract: This invention relates to a workpiece loader which loads workpieces onto a continuously moving conveyor of a type frequently used in manufacturing factory environments. The workpiece loader is comprised of a short length endless belt which is intermittently moved to stack workpieces against a movable fence. Movement of the movable fence is coordinated with motion of the loader belt to enable groups of workpieces to be placed on the conveyor as desired. A first embodiment discloses the workpiece loader belt travelling in a direction perpendicular to the continuously moving conveyor, whereas the second embodiment discloses such belts moving in parallel directions.
