  • Patent number: 9038815
    Abstract: An article sorting and conveying device that conveys articles by the vibrations of a movable body provided through an elastic support unit, includes a first vibration unit that imparts a periodic vibration force to the movable body in a direction inclined from a vertical direction; a second vibration unit that imparts a periodic vibration force in a direction crossing the periodic vibration force by the first vibration unit; and a vibration control unit that causes a periodic vibration force imparted by each vibration unit to have a phase difference and occur simultaneously at the same frequency, and that creates an elliptical vibration trajectory in the movable body. The articles are sorted and conveyed on the movable body by setting the vibration trajectory of the movable body by the vibration control unit such that articles having a different coefficient of friction are conveyed in different directions.

  • Patent number: 4979608
    Abstract: A three mass, two trough feeder transfers articles on first and second troughs by vibrating the troughs. First and second leaf springs support the troughs on a base with the troughs in line with each other and with one trough overlapping the other. The ratio of the spring constant of the first leaf springs to the first trough mass equals the ratio of the spring constant of the second leaf spring to the second trough mass. An electromagnetic driver between one of the troughs and the base is excited with a signal having a frequency with an angular velocity equal to the square root of the ratio. A plurality of feeders may be positioned radially outwardly about the periphery of a conical head for distributing articles.

  • Patent number: 4565279
    Abstract: A vibratory apparatus and method is provided for cooling product as it is conveyed from one station to another. The vibratory apparatus has a conveyor with means for sensing a predetermined weight of product accumulated at a loading portion of the conveyor whereupon the conveyor is operated to convey the product along the conveyor. When the product has been conveyed a sufficient distance along the conveyor for the weight of the product on the loading portion to fall below a second predetermined weight, the sensing means stops the conveyor. The continuously fed product again accumulates on the loading portion of the conveyor until the sensing means senses the first predetermined weight for again operating the conveyor. The cycle is continuously repeated. The accumulated product dwells a sufficient period of time on the conveyor to cool the product which cooling is aided by the vibratory conveying action.

  • Patent number: 4226326
    Abstract: A shaker conveyor is disclosed which includes a conveyor trough supported for reciprocating movement and having drive means including a pull rod adapted to effect reciprocating movement of the conveyor in a manner to advance discrete particles therealong. The conveyor trough has a resiliently mounted discharge end adapted to withstand forces which might otherwise tend to damage the trough and pull rod, and the pull rod is adapted to undergo axial foreshortening when subjected to predetermined axial loading so as to prevent damage thereto.

  • Patent number: 4146123
    Abstract: A method of aligning sticks in which the sticks are oscillated in a receiving zone where they are aligned and conveyed to a collecting zone where they are stacked in parallel side-by-side relationship. The collecting zone is vibrated to dispense the sticks laterally, still in parallel alignment. An aligning tray has two sets of parallel, elongated channels and is reciprocated vertically and in a direction parallel with the channels. Randomly oriented sticks are fed to the first set, aligned in the channels, fed to the second set, which has half as many channels, and then fed through sloping chutes to a set of hoppers. The hopppers and chutes are vibrated vertically and receive the sticks in parallel stacks. The vibrating motion causes the sticks to leave the hoppers laterally and roll down ramps to a non-vibrating conveyor belt which translates the sticks in a direction perpendicular to the long dimension of the sticks to a receiving location.

  • Patent number: 4134489
    Abstract: The invention relates to a coupling device acting between to adjacent tubs of a scraping conveyor for mines in which each tub comprises two side members.The recesses for the abutment flanges, like the access openings, are laterally accessible. The retaining partition of the male connecting member is positioned behind the projecting portion of this member. The cross-section of the connecting spindle has dimensions which differ in at least two directions, which are preferably perpendicular to one another. As regards the partition, the width of the access opening of each connecting member is smaller than the maximum dimension, but greater than the minimum dimension of the spindle cross-section. The spindle locking means are arranged so as to prevent the spindle appearing in front of the opening in a position in which the small dimension of its cross-section coincides with the width of the said opening.

  • Patent number: 4133424
    Abstract: The invention relates to connecting members for the ends of adjacent tubs of a scraper conveyor for the use in mines in which each tub comprises two side members.The supporting partition of each connecting member has a rear face serving as a support for one of the retaining flanges and extends transversely up to the corresponding side member or up to its extension. The supporting partition is located at the rear end of the projecting portion of the male member. The width of the lateral access opening for each partition is less than the maximum dimension of the cross-section of the corresponding locating slot of the partition. The junction zones between the lateral access opening and the locating slot at the partition constitute a lateral locking means for the connecting rods relative to the partition.

  • Patent number: 4081075
    Abstract: Fast-assembly flume apparatus for transferring fish during fish loading and unloading operations. The apparatus includes a plurality of like, generally half-hexagonal flume members. These flume members are nestable to permit compact stowing and are positionable in a longitudinal array for transferring fish along a desired path. A power-driven endless belt may be built into auxiliary units of the flume members to facilitate fish transfer.
