  • Patent number: 4493413
    Abstract: A bucket conveyor assembly includes both a bucket endless conveyor and a cover endless conveyor, with the cover endless conveyor being located inside a horizontal section of the bucket endless conveyor. The cover endless conveyor is driven so that covers (40) mounted on its lower flight are superimposed with gaps (44) between buckets (24) mounted on the bucket conveyor at a loading zone (26). Material to be loaded into the buckets is gravity-fed between the top and bottom flights (36A and B) of both the bucket endless conveyor and the cover endless conveyor and dropped into bottom-flight buckets (24) through the bottom-flight covers (40). The covers have an unsymmetrical inverted V-shape, with the leading side (46) of the V being on a steeper angle than the trailing side (48) of the V.

  • Patent number: 4492298
    Abstract: A machine for connecting rows of coil springs together into a coil spring assembly. The machine initially picks up a row of coil springs by inserting a pick up finger into the barrel of each coil and moving the springs onto a support platen. While transporting the coils, the pick up fingers change the spacing of the coils. The springs are then compressed against the support platen to a desired height through use of a reciprocable compression bar. Thereafter, rotatable transfer fingers remove the springs from under the compression bar, and move them into clamping dies. Leading rotary transfer fingers on the transfer shaft first pull the row of springs out from under the compression bar, and trailing rotary fingers then push the springs into the downstream one of upper and lower clamping dies. The rows of clamping dies clamp together the upper and lower end loops of the leading and trailing rows of coil springs.

  • Patent number: 4492510
    Abstract: A mechanism for driving a robot hand mounted on a robot arm includes a pair of planetary gear assemblies coupled to motors for swinging the robot hand about a first shaft and for rotating the robot hand about a second shaft through transmission systems. During swinging motion of the robot hand about the first shaft, rotative power from the motor which causes such rotation is transmitted by the planetary gear assemblies to the second shaft also, so that rotation of the robot hand resulting from the swinging motion of the robot hand can be cancelled out.

  • Patent number: 4484676
    Abstract: A conveyor with a plurality of article supporting stations has a reciprocatable shuttle mechanism equipped with dogs which engage and advance articles one station on each advance stroke of the shuttle. All dogs are set in article engaging position at the end of each return stroke of the shuttle. A series of accumulating stations extends from the unloading toward the loading end of the conveyor, and accumulating mechanism actuatable independently of the shuttle is operable to reset the dogs of each of these stations to non-engaging position in response to the presence of articles. A control system normally operates the conveyor on a simple cycle of successive advance and return strokes of the shuttle until, with articles detected at the last two stations, the accumulating mechanism is cycled prior to a shuttle advance stroke.

  • Patent number: 4480739
    Abstract: A method and apparatus for separating, ordering, and feeding metallic workpieces, particularly hard-to-handle workpieces which become easily entangled with one another, from a disorganized pile of workpieces. A traveling electromagnetic field is produced by a three-phase motor stator. The stator may be of the linear type, or either internal or external rotor type, cylindrical three-phase motor stators. Metallic workpieces are disposed within the traveling field, and experience stochastic motions therein. When organized, the metallic workpieces are oriented substantially perpendicular to the direction of travel of the traveling magnetic field. Discharge channels may be provided to transport the oriented workpieces to a pick-up point.

  • Patent number: 4461378
    Abstract: A conveyor assembly follows a pathway defined by a supporting framework, wherein the pathway may include serpentine portions. The framework supports a transport mechanism for movement along the pathway, and a belt assembly is carried by the transport mechanism. The belt assembly includes a continuous belt having flexible convolutions permitting the belt to follow serpentine portions of the pathway and also permitting the belt to locally laterally tilt for side discharge without requiring the transport mechanism to similarly tilt. A pivotal member between the transport mechanism and belt assembly permits the belt to tilt laterally, such as on a hinge point laterally offset from the center of the conveyor pathway. An actuator causes a selected portion of the belt to tilt on the hinge point.

  • Patent number: 4458807
    Abstract: A conveyor chain has longitudinally elongated coupling links having transverse throughgoing bores and longitudinally elongated entrainment links each formed with a transversely throughgoing window having a relatively wide central section and a pair of opposite relatively narrow end sections centered on respective parallel and transverse axes. Respective coupling pins have central regions of a cross-sectional size that can fit axially through the central section but not through the end section of the respective entrainment link and ends formed with axially limited regions of reduced cross-sectional size interfittable with the ends of the windows. These limited regions have end faces axially flanking the respective entrainment link. Thus the pins pivotally connect the links together into an annular succession with the entrainment and coupling links normally alternating with each other.
