  • Patent number: 8727098
    Abstract: A system for aligning items, such as bottles, includes a rotating plate and a diverter arm that extends outward over a top surface of the plate towards the plate edge. A rotating channel may surround the plate. In operation, bottles are dropped onto the plate and rotated by the plate against the arm. The distance between the top surface of the arm and the plate surface is such that the arm generally diverts the bottles outward and guides them into free gaps within the channel. The distance is also configured such that as bottles back-up, waiting for free channel gaps, the arm allows any buckling bottles to pass over and back onto the plate, rather than into the channel. The distance may also be configured such that the arm acts like a scoop. As bottles back-up behind the arm, the arm presses under the bottles along the arm and passes them over, relieving the pressure.

Pulses of compressed gas are intermittently employed to lift components upon detecting the absence of a component in a portion of such buffer zone. The grooved chute member has a shape resembling the symbol for a square root after replacing the angles with curves. The stream of flowing components can be quite fast because components are directed to fall into the downsloping gathering portion of the grooved chute at an upper, middle, and lower portions.

A flow leveler 40, 54, 80, 90 is positioned along the tray floor and normalizes the flow of product moving along the tray. In its preferred embodiment, the flow leveler includes a plurality of elongate ramp members 82, 92 laterally spaced between the tray sides, and optionally arranged in staggered rows. The flow leveler may include a planar leveler floor 48 for positioning within a cutout in the tray floor and a plurality of securing members 42 for movably securing the leveler floor to the tray. The inclined ramp surface of the leveler is preferably angled up to 25° to 45°. The flow leveler is particularly well suited for leveling the flow rate of irregularly shaped snack goods conveyed along the linear motion conveyor.

  • Patent number: 6116409
    Abstract: An apparatus for uniformly distributing parts on a conveyor surface which includes a storage bin for holding randomly oriented parts in bulk, a conveyor adjacent the storage bin for acquiring a fragment of the randomly oriented parts in the storage bin and delivering that fragment of randomly oriented parts to a chute, a vibratory conveyor receiving the fragment of randomly oriented parts from said chute, and a belt conveyor for receiving the randomly oriented parts from said vibratory conveyor. The vibratory conveyor includes at least one rib projecting upward therefrom and extending across at least a section of the vibratory conveyor perpendicular to the direction of conveyance, the at least one rib acting as a flow obstruction to cause the randomly oriented parts traveling on the vibratory conveyor to gather and spread across a width of said vibratory conveyor to thereby spread more uniformly on the vibratory conveyor after passing over the at least one rib.

  • Patent number: 6112883
    Abstract: In order to provide the capability of distributing a material that is conveyed, a vibratory distribution conveyor includes a deck having a distribution edge. The distribution edge extends between an inlet end and an end remote therefrom and the deck is subjected to vibratory motion to cause material to be conveyed from the inlet end toward the end remote therefrom. With this arrangement, the declination of the deck is controlled about a longitudinal axis to control the distribution characteristics of the conveyor.

  • Patent number: 6047811
    Abstract: A vibratory conveyor and method of making the conveyor having a frame to which a locator sheet having accurately punched and shaped locator holes for locating spring mounts fixed to the frame. Each mount preferably is a plug having corners which engage notches of one of the holes to accurately locate the plug. Each hole also has a portion which extends beyond the periphery of the plug to expose the frame so that the plug can be welded to the frame. After welding, a protective washer is slipped over each plug and welded to the plug and sheet. When located and fixed in this manner, each mount is located relative to one end of the conveyor, angularly located, and horizontally located. The sheet or another locator sheet can also have other holes to locate other conveyor components such as cross tubes, braces, and the conveyor drive. Each sheet preferably is constructed of corrosion resistant cladding for enabling a less corrosion resistant material to be used for the frame.

  • Patent number: 5704466
    Abstract: The vibratory feeder utilizes a releasable attachment mechanism for connecting a feed tray to a vibrator for ease of removal and installation. The attachment mechanism has a first coupling in the form of z-blocks which when pressed together align the feed tray with the vibrator and firmly affix the tray against motion toward and away from the vibrator at the coupling. A second coupling displaced from the first coupling utilizes two pin blocks which are locked together by two press-fit pins. The pin blocks, when locked together, firmly fix the feed tray to the vibrator at the second coupling and simultaneously press the Z-blocks together at the first coupling.

  • Patent number: 5660265
    Abstract: A vibratory conveyor for particles of tobacco or other bulk material has a trough with an elongated bottom wall the upper side of which merges smoothly into a downwardly sloping convex cylindrical or substantially cylindrical external surface of a tubular or like member forming part of the front portion of the trough. This ensures that fragments of dust (if any) which are being entrained by the particles of bulk material are less likely to be expelled or permitted to escape from successive increments of the flow of bulk material advancing beyond the bottom wall of the trough. Moreover, the particles of conveyed bulk material are more likely to remain in their prescribed path.

  • Patent number: 5646374
    Abstract: A vibratory conveyor for a combination weigher or the like includes an elongated trough having inlet and outlet ends and a pair of upwardly extending and outwardly flared side walls. The conveyor also includes a pair of ramps for lifting and slowing a flow of particulate material as it is conveyed along the length of the conveyor. A first of the ramps includes a relatively flat base portion and two sloping side portions that converge at the apex of a V-shaped end portion to bias the flowing material toward the center of the trough. A second ramp has a relatively flat portion and further slows the flow of material so that it drops off of the outlet end of the conveyor in a mere trickle.

  • Patent number: 5575378
    Abstract: A method and apparatus for transferring relatively light objects. The objects are supported on a cushion element having a multiplicity of extremely fine and relatively short flexible fibers packed at an ultra high density pile in a backing. The fibers are aligned at an angle or inclination with respect to the base so that when the cushion element or the object is vibrated the objects are transferred in the direction of lay of the fibers.The cushion element may be supported by a base with the object resting on the fibers, or the cushion element may be secured to the underside of the object so that the fibers rest on the base.

  • Patent number: 5558199
    Abstract: An apparatus for manipulating a multilayer stream of tobacco particles with randomly intermixed foreign particles has a vibratory conveyor which advances the stream toward and discharges successive increments of the stream onto the upper reach of an endless belt or chain serving to advance the increments at a speed exceeding the speed of advancement of the stream by the vibratory conveyor. The endless belt or chain discharges a single layer of tobaco particles and foreign particles, and such single layer is caused to move past a segregating unit which detects and expels foreign particles therefrom.
