  • Patent number: 7568572
    Abstract: A control architecture for material handling includes multiple tiers of controllers, such as three. The lowest-level controllers interact directly with sensors and actuators used in the material handling system, such as photo-eyes and motors used with conveyors. The lowest-level controllers receive higher level commands from one or more mid-level controllers. The mid-level controllers, in turn, receive still higher level commands and information from at least one upper level controller. Each mid and low level controller is designed to include sufficient intelligence to deal with many of the signals and messages it receives without having to forward those signals or messages to the next higher level controller and await instructions from that higher level controller. The system thus distributes intelligence amongst the controllers. The system is well-adapted for application to conveyor control systems.

  • Patent number: 6601694
    Abstract: A chip plow conveyor for conveying abrasive scrap includes an elongated trough having a flat bottom and sides, and a chip-motivating pusher bar. The pusher bar moves longitudinally and floats laterally as the pusher bar reciprocates to move scrap along the trough. Lateral floating of the pusher bar helps overcome binding caused by scrap material wedging between the pusher bar and one of the sides, but wedging still causes the pusher bar to engage the sides with substantial force. The pusher bar includes a bearing component with beveled front corners on a leading end of the pusher bar, with the inclined ramps providing angled engagement with the sides and characteristically providing a longitudinally-angled corner surface arrangement that cannot be sharpened into a knife-simulating edge even after substantial wear against the flat bottom and the sides of the trough.

  • Patent number: 5140716
    Abstract: Fixed parallel cargo rails are positioned on the cargo bed floor of an aircraft, spaced sufficiently to fit a pallet snugly therebetween. A plurality of collinear slots arranged along the length of the cargo bed floor are positioned just inboard of each rail. The slots are evenly spaced and oriented lengthwise with respect to the cargo bed floor. A dog extends above the cargo bed floor from each slot and is adapted to engage a notch in the cargo. While engaged, the dog is adapted to move along its slot, thereby moving the pallet lengthwise along the cargo bed floor. The pallet is passed bucket brigade style from one dog to the next.Another aspect of the invention is the employment of movable cargo rails on the cargo ramp. The rails are slidable widthwise across the ramp within mounting slots, thus permitting the spacing between the rails to vary. The result is that loading cargo onto the ramp and aligning it with the fixed cargo rails on the cargo bed floor is made much easier.

    Abstract: Apparatus for gathering particulate material in mines and similar plants has a mobile platform which collects particulate material and surrounds the trailing end of a material removing conveyor. The sides of the trailing end of the conveyor are flanked by plate-like carriers on each of which are fixed several beams serving to push gathered material toward and onto the conveyor in response to movement of the carriers toward the conveyor. The carriers are movable toward and away from the conveyor by motors which are installed beneath the platform, and the apparatus further employs stationary or reciprocable barriers, one behind each beam, which prevent the beams from pushing material away from the conveyor during return strokes of the carriers. Those ends of the beams and barriers which face in the direction of forward movement of the platform slope forwardly and downwardly to facilitate penetration beneath the accumulations of particulate material on the platform.

    Abstract: A transfer apparatus which is designed to transfer workpieces at different pitches by a plurality of transfer bars. The apparatus has a horizontal guide provided on a frame which supports first and second transfer bars in such a manner that these transfer bars are movable axially in the horizontal direction, and at least one slider block is slidably guided in parallel to the transfer bars through the guide. This slider block is provided with a driving motor and further provided with a mechanism which is arranged to allow the slider block to slide along the guide by the rotational force derived from the motor. An arm which is pivoted by the rotational force from the motor is pivotally supported on the slider block. Further, a first and second transmission are provided for transmitting the movements of the slider block and the arm to the first and second transfer bars, respectively.

  • Patent number: 4768646
    Abstract: An accumulator conveyor having a load support frame defined by side rails each having a series of idler wheels, the load support frame defining a load support plane adapted to support a series of loads along its length. A shuttle frame is reciprocable relative to, and preferably supported by, the load support frame. The shuttle frame carries a series of pusher bars spaced one from the other to define a series of load stations along the conveyor's length. A novel drive mechanism reciprocates the shuttle frame, and therefor the pusher bar assemblies, relative to the stationary load support frame, for indexing any load on the load support frame from an upstream station to an adjacent downstream station. The conveyor also includes a novel station lock out system which causes the pusher bar of a station to be latched down beneath the support plane of the load in that station when loads are parked in all stations downstream therefrom.

  • Patent number: 4687409
    Abstract: There is disclosed article handling apparatus (10) which is primarily intended for transferring ammunition shells to and from a storage magazine in a mobile weapons system such as a tank or warship. The apparatus comprises a storage magazine having a storage rack on which the articles can be stored, and an indexing-type conveyor for traversing the articles along the storage rack. The conveyor moves through an indexing cycle in which it has a starting position in which it is engageable with a first batch of articles, causes one increment of traversing movement of the batch, releases itself from the engaged first batch, returns to the starting position and engages with a second batch of articles. A restrainer is provided, including a cam bar, which operates to locate any articles which may be present on the storage rack against up and down movement and also against traversing movement while the apparatus is in its storage mode.

  • Patent number: 4082178
    Abstract: A reciprocating harpoon-type conveyor for transporting swarf-like material along a conveyor trough is provided with non-jamming barbs each of which comprises a multi-faced member secured to the inside surface of the upwardly extending walls of the conveyor trough. Each barb has an inwardly-slanted feed surface which increasingly projects into the conveyor trough in the downstream direction and a rearwardly slanted retaining surface which extends upwardly in the upstream direction and away from the bottom of the trough. An upstream edge portion and a downstream edge portion of each barb substantially merge with an upstanding wall of the conveyor trough. The feed surface is adapted for slidable passing of swarf-like material thereover as the material is moved forwardly in the conveyor. The slanted retaining surface is adapted for engaging and retaining a portion of the swarf-like material in place as the harpoon is retracted from a forward position to a rearward position during return stroke.
